Compare and Contrast: Cinema or Movies at Home Essay
The average American spends about $2,000 a year on entertainment. Many people can conclude that watching a movie in a cinema is very memorable and interesting. Although a cinema doesnââ¬â¢t compare to the privileges you have at home. Then again your home cannot provide you with a huge screen and a big volume. Being at a cinema has its benefits but watching a movie at home easier and inexpensive. In a cinema you get to watch the movie on a huge screen with a comfort volume surround sound system. The graphics are way better than your small box television. When you go to the movies you must be on time. You also have to be courteous to others around you and respectful otherwise you could get thrown out. At the movies you do not have a remote to pause in case you need to go to the restroom or ask what is happening in the movie itself. At the movies you do not get to recline in a comfy chair. You must sit properly and make sure you donââ¬â¢t bother others around you. At the movies you have to whisper if you need to talk. Then when there is a terrifying part you are strained from screaming or youââ¬â¢re at the hilarious part in the whole movie and you have to stifle your laughter. Being in a cinema there are many rules you must go by while at home you may have some rules but not as strict. Then if you donââ¬â¢t like the movie at all it was a waste of time and money plus no refund. There are many disadvantages when going to the movies even with the few pros the cons overpower. Now when you go to the movies you get to choose your time to start the movie. There is no limit as to when you must be in a chair watching the movie. Plus you can skip all the boring previews and get straight with the movie. Then you can add subtitles if you would like where at the movies you donââ¬â¢t have that choice. You get to recline in your personal sofa and you can wear your pajamas! You donââ¬â¢t need to dress like you would if you were in public you can be comfortable in your own home. This also gives you a sense of security and ease. Then this creates a bond with you and whoever you decide to watch the movie with. You could also watch previous movies prior to the new movie you want to watch. You have your own personal marathon with friends and family. The relationship between you and your friends or family builds and is good in the future. Plus at home you can invite anyone you want free of charge and you donââ¬â¢t have to worry if someone will have the money or not. You donââ¬â¢t have to waste so much money on buttered popcorn that is cheaper by the box and you get more than you would in a large bag at the cinema. Then if you feel that you need to go to the bathroom you have a remote to pause the movie. You get to watch the whole movie and you donââ¬â¢t even miss a single part. Also in case you get lost throughout the scenes you can pause and ask those you are watching the movie with what is happening. Then fast forwarding and rewinding are also an option you can do at your home. In addition you do not have to worry about others ruining the movie experience for you. You do not have to refrain from screaming, laughing, crying, sighing, est. during the movie.

Forgive my Guilt Essay
Who was the poet who wrote the poem ââ¬Å"Forgive my Guiltâ⬠? Well the poet who wrote the poem ââ¬Å"Forgive my Guiltâ⬠was the American poet Robert P. Tristram Coffin. Robert was born on March 18, 1892 at Brunswick, Maine. Robert won the Pulitzer Prize for his poem ââ¬Å"Strange Holinessâ⬠in 1936. His poems were based on New England farm and his voyage life. His poems were committed to cheerful acts for the world. Sadly Robert died on January 20, 1955 at Portland, Maine. In the poem ââ¬Å"Forgive my Guiltâ⬠the poet uses rhyme, imagery and simile to make us understand and visualize the poem better. The speaker in this poem is the author. The author is talking about his summer when he was younger. He uses simile in the quote ââ¬Å"They cried out like two sorrowful high flutesâ⬠meaning that the two birds cried sound like an out of tune flute that sounds horrible. He uses imagery because it helps me picture that two birds have been injured, by telling us that he had a pellet gun and shot the poor birds. The poem starts by saying ââ¬Å"Not always sure what things called sins may be, I am sure of one sin I have done It was years ago, and I was a boy. In this sentence the author is admitting that he have done a sin when he was younger. A sin is when you have done the wrong action, a regrettable action. It continues to say ââ¬Å"I lay in the frostflowers with a gunâ⬠he is started to say that he was lying on the ground filled with frostflowers. Then it says ââ¬Å"The air ran blue as the flowers, I held my breathâ⬠when he said the air ran blue he reflects the sky. Then it says ââ¬Å"Two birds on golden legs slim as dream thingsâ⬠he is making us visualize by telling us that the sun was reflecting the birds legs. Then it says ââ¬Å"Ran like quicksilver on the golden sandâ⬠when he said this he meant that he was running on the beach. Then it says ââ¬Å"My gun went off, they ran with broken wingsâ⬠he said that he fired his gun and shot a bird and that bird was trying to fly with a broken wing. Then it continues to says ââ¬Å"Into the sea, I ran to fetch them in, But they swam with their heads high out to sea,â⬠he said that he knew that he shot a bird so he ran towards to see if the birds were fine but the birds swam away toward the sea. Then it continues to say ââ¬Å"They cried like two sorrowful high flutes, with jagged ivory bones where wings should beâ⬠when he said that ââ¬Å"they cried like sorrowful high fluteâ⬠he meant that their cries sounded like an out of tune flute, which sounds horrible and then when it says ââ¬Å"with jagged ivory bones where wings should beâ⬠he is telling us since he shot the birds, he left the birds wounds. Then it continues to say ââ¬Å"For days I heard them when I walked that headland Crying out to their kind in the blueâ⬠he tells us that he went back to see the birds and saw that the birds were telling something to their herd. Headland is when your near a fence or border. Then it says ââ¬Å"The other plovers were going over south on silver wings leaving these broken twoâ⬠he said that the plovers sadly left the two birds and headed south without them. Then it says ââ¬Å"The cries went out one day but I still hear them Over all the sound of sorrow in war or peace I ever heard, time cannot drown them. â⬠He said that the cries of the birds followed him everywhere he goes not matter what he was doing he still heard their cries. Then it ends by saying ââ¬Å"Those slender flutes of sorrow never cease. Two airy things forever denied the air! I never knew how their lives at last were split, But I have hoped for years all that is wild, Airy, and beautiful will forgive my guilt. â⬠The author is telling us that the cries never stopped, he has heard their cries for many years, he is saying that he is sorry for the sin he has done and finally apologize for the guilt he has committed when he was younger. The poem is telling us to think before we commit something because you never know that the actions you decide might haunt you forever. It also says to always think twice because when you decide to do something and do it, you might regret it because you canââ¬â¢t go back in time and change your actions. This poem brings a good message to me. It helped me realize that I have to always think twice because I might regret doing something and if I donââ¬â¢t think twice the action I committed my haunt my life forever. Knowing this I will always think twice before I do something. When you read this analysis hopefully this poem brought you a lesson, a lesson in which tells you to always think twice before you commit something youââ¬â¢ll regret throughout your life!

Complete Persepolis/Season of Madness
The Complete Persepolis/ A Season of Madness These two selections are based on completely different scenarios. One takes place in Iran during its countryââ¬â¢s revolution with Marjane, a girl trying to figure out who she is and wants while having to face her countries conflicts that affect her. The other story takes places inside a home were a woman named Fatin feigns madness and is having to do desperate things instead of admitting to an adulterous affair she had.Although these two stories may seem like they have nothing in common, these two selections have certain particular points that can be compared among each other. The three points that can be compared are about the mother, husband, and protagonist positions. Marjiââ¬â¢s mother better known as Mrs. Satrapi or Taji s in The Complete Persepolis is a passionate woman, who is upset with the way things are going in Iran, including the elimination of personal freedoms, and violent attacks on innocent people.She actively takes part in her local government by attending many protests. Marjane's mother is very family oriented. She cares very dearly about her daughter Marjane, so much that she is willing to do anything for her happiness. She and Marjane's father were the ones who decided to send Marjane to Austria. The reason they did this was because they wanted Marjane to be safe and have a better life. The only way she could be safe is to get away from the war that was going on at the time. Majane's mother only wants her daughter to be happy.She goes far distances to do so, like going and visiting Marjane in Austria and helping Marjane with her and her husband Reza's wedding even though she did not agree with it and that shows again that she is willing to do anything for her daughter as long as sheââ¬â¢s happy. In A Season of Madness, the mother ââ¬âin ââ¬â law shows no compassion. The mother-in-law is a commonly disliked figure in Arab culture, especially when she is the matriarch of the larger family. It seems as if Fatin is being controlled be this older woman that shows to have no interest towards her.At the end of the story when Fatin confesses to her unfaithfulness the mother-in law reacts with a very unlikeable personality with an attitude of her just wanting Fatin out their lives. Then his mother was clasping my hand, twisting her mouth into a grimace of pity and murmuring, ââ¬Å"Sheââ¬â¢s crazy, poor thing. Nothing can be done for her. â⬠(745) Marjaneââ¬â¢s husband Reza served in the Iran army. Reza used to be a womanizer but when he met Marjane that all changed. He was into art just like Marjane, and took it very seriously.He shared love for life like Marjane and he also didnââ¬â¢t take the Iran government too seriously. Him and Marjane dated for a while and ended up getting married but they both changed which lead to fighting which ultimately lead to a divorce. Reza is important because he helped Marjane chase her dream of getting into the career path of art by applying to University of Tehran with her. So overall, Reza was a good husband to her that helped her along the way of finding herself. Fatinââ¬â¢s husband is very compassionate and loving and vows to stay with her no matter what. Poor thing, sheââ¬â¢s so young. I swear to god, Iââ¬â¢ll take her anywhere in the world to find a cure for herâ⬠(745) Fatinââ¬â¢s husband although at a point makes her seem as though she was invisible and almost as childlike only showing that his feelings are sufficient. It seems as if he was being selfish by ignoring all the things she did to get a divorce and still wanting her there with him no matter what. Influenced by her liberal parents, Marji is outspoken, aware of her environment and spends more time reading books than playing with toys. A believer in God and Marxism, and rebellious at times.Marji is a strong girl, who follows in her parents footsteps. Even though Marji ââ¬Ës view of the world changes as she gro ws, from a small little girl to a full grown woman, her feelings on life remain the same and has always been a fighter. She had many experiences throughout her life; she was the new kid at school, had to make new friends, got into the wrong crowd, smoked cigarettes, smoked weed, had boyfriends, and many other things. Marjane strongly believed in fighting for what you believe in. Sometimes her actions seemed rebellious, and they got her into trouble, but this didnââ¬â¢t change her feelings or ambitions.Fatinââ¬â¢s greatest desire is to discover her ââ¬Å"real selfâ⬠through creativity and independence, and to find her individual place in society. Fatin is suffering by being in a relationship with a man that she does not love. Fatinââ¬â¢s discovery of painting as an outlet is shown when she says ââ¬Å"I stumbled along in my madness, never meeting my real self except when my eyes fell on the watercolors, which the strange light in this African country had inspired me to paint: it was a light that broke the hold of the sunââ¬â¢s burning rays for a short time at daybreak and dusk.I often wondered if I should tear these paintings down from the walls, in case they were what made my husband keep hoping that the old Fatin would return. â⬠(Al-Shaykh 742) Fatin hides her pain and confusion through her paintings because she feels her marriage, children, house and sex is not fulfilling. She turns herself into a really disgusting human by doing things such as not brushing her mouth or not wearing protection during her period. She remains invisible, unrecognized, and a woman without a voice.The protagonists in these two stories seek freedom of expression and look for a voice in their own particular way. They refused to be helpless, unhappy, and an act of their own initiative to reject the role patriarchy has reserved for them.

Radical Shakespeare a new way of doing Shakespeare Essay
Radical Shakespeare a new way of doing Shakespeare - Essay Example eâ⬠and when used as a noun in terms of ââ¬Å"a person who supports great social and political change.â⬠2 Working from these definitions, it should not be surprising to learn that ââ¬Å"radical theatre aims to make extreme changes in existing views, habits, conditions or institutions.â⬠3 However, this simple definition is deceptive as the concept of radical theatre becomes much more complex in the various ways through which this alternative approach might be applied ââ¬â whether by protest, aesthetic differences or through other forms of expression. In his pamphlet discussing the various forms of radical theatre, Richard Walsh identifies three distinct approaches to radical theatre that can be generally classified as aesthetics defining politics, politics defining aesthetics, and aesthetics obscuring politics ââ¬â ââ¬Å"the social and political dimensions of theatre were truncated to allow an exploration of the encounter between the theatrical medium and the individual perceiving mind.â⬠4 This idea of the use of the term radical to describe the theatre can be best understood by examining the work of a radical director such as Peter Brook. Therefore, this essay will consider in which ways, and to what extent, the work of Peter Brook can be regarded as radical. In order to develop an understanding of the radical changes that Peter Brook and others brought to the stage, it is necessary to first have a concept of the world of theatre as it existed before Brook entered the scene. The commercial structure of early British post-war theatre was characterized by the classical teachings of the upper/middle classes who felt theatre should reflect a particular adherence to tradition. Coming out of the war, much of Britainââ¬â¢s mainstream theatre was dominated by the ideologies of a relative minority of commercial businesses who were merely seeking a profit rather than being overly concerned with any kind of artistic achievement. If a theatre company wished to garner the

Color Research Paper Example | Topics and Well Written Essays - 1250 words
Color - Research Paper Example Color may be quantified and described by the extent to which they stimulate different types of cone cells (Travis, 2003). This is because color perception stems from different spectrum sensitivity of various cone cells in the retina to various parts of the spectrum. The physiological or physical color quantifications do not fully describe the color appearance and its psychophysical perception. The science of color is referred to as chromatography, color science or chromatics (Farndon, 2003). It involves color perception by the brain and human eye. Human perception of color originates from composites of light, photonsââ¬â¢ energy spectrum entering the eye. The retina contains photosensitive cells on the back of the eyeââ¬â¢s the inner surface. These photosensitive cells are composed of pigments absorbing visible light (Savage, 1998). There are two classes of photosensitive cells: cones and rods. Cones are responsible for human ability to distinguish between various colors (Klein er, 2004). On the other hand, the rods sense light intensity variations and are effective in dim light. Rods sense the flux of no photon energy, the incident photons. Therefore, whenever there is a dim light, human eye do not perceive colored objects as shades of color, but as shades of grey (Travis, 2003). Diagram of color and light Perception of color in the retina is done by photoreceptor cones which are sensitive to photons whose energy widely extend beyond the green, blue, and red spectrum portions (Kleiner, 2004). Color vision is often possible because of the differing photon energy sensitivity of the sets of cones (Savage, 1998). For every flux of photons or color signal, a ration of response in the different sets of cones is triggered. This ration is what permits color perception. During the day, human vision is effectively mostly in the blue-green where the spectrum of the sun is in its maximum region (Travis, 2003). Color sensation primarily depends on light composition, a mixture of colored light and white light (in itself can be wavelength mixture, like purpleââ¬â¢s case) (Farndon, 2003). The colored light may have dominant hue or wavelength. The degree to which the wavelength dominates is referred to as chroma, saturation. This saturation, chroma decreases as the white light deletes the wavelength. There are 3 receptors that respond to various wavelengths in the eye. This results in attempts to chart colors via e primary lights mixture. A good number of colors are produces through mixing lights originating from the 3 primary lights. However, not all colors can be produced in this manner (Savage, 1998). Color vision development in human beings is an interesting process of evolution (Kleiner, 2004). The human eye is not in a linear straightforward development. Development of color vision begins as a light sensitive pigment and then differentiates on a smaller creature to create structures that are sensitive to light (Savage, 1998). These light se nsitive structures disperse in the forming eyeball and turns to be the retina. Initially, retina was like a moving sensor. However, it developed the ability to delineate fine details and to see color. The evolution of the eye and color perception is a standard development seen in all vertebrates and many non-vertebrates. So what is color? Why does retina develop ability to see color? (Farndon, 2003). Color is a visual perception that corresponds in human to the categories referred to as blue,

The importance of Coaching within Raising Employee Perfomance Research Paper
The importance of Coaching within Raising Employee Perfomance - Research Paper Example When there individuals within an organization that need to enhance their skills for better operations, coaching thus is done on them to improve their delivery potential as well as make those individuals more productive to the organization (Charness, 2014,pg.87). Coaching therefore will target areas such as skills that need to be developed or strengthened; the lapses that exist in work; behavior and performance output of individuals. When these weak areas are recognized within an organization, the employees are taken through coaching by the managers or supervisors depending on the organizations policy (Charness, 2014, pg.35). A case study that reveals the benefits of coaching can be drawn from the UK rail industry where up to 13 coaches were tasked with the responsibility of increasing the skills of customer service for about 350 people in their organization (customer hosts). As a tool to improve employees output, coaching has had other numerous benefits to UK rail industry including: nurturing and improving an individualââ¬â¢s talent; setting expectations about the employee and making the organization managers accountable; engaging leaders in organization activities; professional satisfaction; boost of employee morale; and overall improvement of the organizational goals. This report therefore aims to discuss coaching explaining its purposes; benefits; and challenges. Additionally, the report will give a brief conclusion on the topic of study. Coaching can be defined as process that enables an individual to learn and develop skills from a direction and advice provided by a seasoned expert or professional (Crane, & Patrick, 2014, pg.89). Additionally, coaching can be understood as a process that involves directing, training as well as instructing an individual or a group of persons to develop certain skills necessary to achieve some goal. Directions can be given through motivational talks while trainings offered through seminars and

Technology trends Essay Example | Topics and Well Written Essays - 2000 words
Technology trends - Essay Example on news channels is immense and in order to retain their customer base, the need for adoption of suitable methods with the help of latest technologies is becoming the need of the hour. There has been found a noticeable change in the preferences of the customers as far as their choice of a particular medium of news delivery is concerned. To strive in todayââ¬â¢s competitive world, it has become a challenge for the leading newspapers to make the news available to it customers as early as possible before its competitors grab the attention of the target audiences. To generate profits, some newspapers have adopted a scheme by which they make some news available for free and some content is marked as ââ¬Ëpremium contentââ¬â¢ which can be accessed on payment of a considerable amount of fees. This strategy helps in building demand for the news within the audiences. Internet journalism has become the order of the day with audiences more interested in gaining information about different happenings across the world through leading newspaper websites rather than the printed newspaper(Group M., et.al., 2005). Web technologies have enabled these companies to gain feedback on the different news articles published on its websites. This helps the newspapers to understand whether any improvement has to be brought in the content or not. E-books have become a popular medium of gaining thorough in-depth knowledge about any topic which needs clarity. Topics can vary from something very theoretical to something very practical like the use of technologies in shaping the businesses of todayââ¬â¢s organisations. E-books help audiences to surf easily through a wide range of books which might not be possible in reality. Audiences prefer e-books as they can have access to a wide range of subjects, story books, fiction books and technology related books without purchasing them physically. Many websites like e-snips and Amazon.com offers a wide range of free e-books to be accessed by its audiences

Differences Between Virtual and Concrete Manipulatives Essay
Differences Between Virtual and Concrete Manipulatives - Essay Example 117). Physical or real-world features do not define a concrete experience in a mathematical context; it is by how significant the connection is to the mathematical ideas and situations. For example, a student might create the meaning of the concept "four" by building a representation of the number and connecting it with either real or pictured blocks. Virtual manipulatives, also called computer manipulatives, appear to offer interactive environments where students can manipulate computer objects to create and solve problems. Furthermore, perhaps because they are receiving instant feedback about their actions, students then form connections between mathematical concepts and operations. However, whether using physical or virtual manipulatives, it is necessary to connect the use of a specific manipulative to the mathematical concepts or procedures that are being studied (p. 119). Some researchers have observed that some of the constraints inherent to physical manipulatives do not bind v irtual manipulatives. Use of models and/or manipulatives gives assessment of mathematical learning a cohesive connection to mathematical instruction (Kelly, 2006). Kellyââ¬â¢s study examines the relationship between mathematical assessment and the use of manipulatives. ... The use of such assessments in combination with the use of manipulatives should build strong student investment in the teaching-learning process while developing deeper mathematical learning. Physical Manipulatives Relative to the teaching and learning of mathematics, physical, or concrete, manipulatives are three-dimensional objects used to help students bridge their understanding of the concrete environment with the symbolic representations of mathematics (Clements, 1999; Hynes, 1986; Moyer, 2001; Terry, 1996). There has been historical documentation of the use of manipulatives such as the abacus, counting sticks, and of course fingers, prior to the Roman Empire (Fuys & Tischler, 1979). Examples of teacher-made manipulatives include those that use materials such as beans, buttons, popsicle-sticks, and straws (Fuys & Tischler). Todayââ¬â¢s teachers have access to a wide variety of commercially available manipulatives designed to aid in the teaching of most elementary mathematical concepts. Examples include Algebra tiles, attribute blocks, Base-10 materials, color tiles, Cuisenaire rods, fraction strips, geoboards, geometric solids, pattern blocks and Unifix cubes. The appearance of commercially made manipulatives in the United States increased during the 1960s after the work of Zolten Dienes and Jerome Bruner was published (Thompson & Lambdin, 1994). Many educators continue to view manipulatives as teaching tools that involve physical objects that teachers use to engage their students in practical and hands-on learning of mathematics. These manipulatives continue to be instrumental to introduce, practice, or remediate mathematical concepts and procedures. Concrete manipulatives come in a variety of physical forms, ranging from grains of rice to
Stem Cell Research Legislation Paper Example | Topics and Well Written Essays - 1250 words
Stem Cell Legislation - Research Paper Example Stem Cell Research Legislation Stem cells are specific non-specialized cells mostly found in multi-cellular organisms and have the capabilities of dividing and differentiating into specialized cells when subjected under particular physiological conditions. Stem cells are categorized into two major groups depending on how each is obtained. The first category is the adult stem cells, which involve stem cells obtained from the body of an adult human being and which are capable of dividing and differentiating to regenerate the exact tissues from which they are obtained. Adult stem cells are said to present in the skin, bone marrows, liver, and brain. Adult stem cells are claimed responsible for every repair that occurs on a damaged skin and confirmed to cure cancer (Jayachandran, 2005). The second category of stem cell is the embryonic stem cells, which are obtained from a developing embryo. The embryonic stem cells are perceived to have massive potential for the treatment of degenerativ e diseases like the diabetes, Alzheimerââ¬â¢s disease, Parkinson disease, spinal cord injuries among other terminal diseases. However, the belief attached to embryonic stem cell therapy on human beings was derived from a successful scientific test, which involved mice. Recently, pluripotent stem cell was innovated and is undergoing research before approval as an alternative source of stem cell. Owing to the fierce controversies that surround human embryonic stem cells research, many concerned countries have formulated laws, which either illegalize or support the research, to shelter the researchers from fear of rejections and assaults by the society. Developed countries like China, the UK, Korea, and Switzerland adopted progressive laws, which encourage the progress of research activities in this field (Schechter, 2010). Meanwhile, some other countries such as the USA tightened their legislations to oppose the research, a stand that has loosened with time. Under this topic, the p aper will mainly focus on USA, a country that has undergone a series of changes in legislations governing human embryonic stem cell research. In the year 1996, the Congress passed a bill called Dickey Amendment, which prohibited the DHHS and the NIH from funding any activity that involves creation or destruction of human embryo for the purpose of research. However, the Bill did not restrict the use of private money in accomplishing the research. In 1998 when a successful isolation of human embryonic stem cell was achieved, DHHS attempted to interpret the bill in favor to federal funding on the research, but the critics of embryonic stem cell research overturned the move. Schechter (2010) avers that upon assuming office in 2001, George Bush announced that federal funding would be provided for research involving already existing stem cell lines. Additionally, President Bush under the rejected the amendment that required the government to relax its orders on the federal funding restric tions. The main historical change in the discipline of stem cell research took place in 2009 when President Obama signed an order overturning the previous orders of George Bush, which limited federal sponsorship on stem cell research (Skene, 2010). In September 2010, another Bill titled the Stem Cell Research Advancement Act of 2010 was presented to the Senate for voting. The Bill required that the federal money allocated for embryonic stem research be extended to cover excess embryos donated from IVF clinics. Furthermore, the bill

Pathos, Ethos, and Logos Essay Example | Topics and Well Written Essays - 500 words
Pathos, Ethos, and Logos - Essay Example In his letter, Jefferson uses Pathos, Ethos, and Logos to argue his point of view. This is a strong, well-written letter. Pathos is used by pointing out the millions of trafficked humans. Ethos is used by Jeffersonââ¬â¢s reference to his belonging to the Human Rights Watch. Logos is used by appealing to specific problems like the lack of statistics and definitions. This letter is impressive mostly on the Ethos and Logos to persuade the reader to understand his point of views. Jefferson makes the reader feel angry and disappointed by the lack of research and measures done by the United States when some countries fail to address trafficking. ââ¬Å"Trafficking is a blatant violation of human rights and is almost universally condemned, yet many countries are failing to address this problem seriouslyâ⬠(Jefferson). He creates emotion to the readers, so they can get the message he wants to share. This is an appeal through Pathos. Jefferson does not show real anger in his letter because it was written for the Secretary of State, so due respect must be given. This is the lack of Pathos from Jeffersonââ¬â¢s letter. Although the reader can feel the anger and disappointment, it is not clear enough. One or two sentences appeal to the Pathos, but mostly logos and ethos were used. An example of one sentence is as follows, ââ¬Å"trafficking is a widespread human rights violation that threatens the lives, health, dignity, and security of millions of people thr oughout the world, with women and children suffering the brunt of the abusesâ⬠(Jefferson). Despite this plea, Jefferson does not use many others. It seems that Jefferson was relying on Powellââ¬â¢s knowledge on the subject, not his emotions. Although Jeffersonââ¬â¢s letter has lack of emotion, the credibility of his letter is really impressive. He used Ethos to strengthen his argument. Frequently Jefferson refers to Human Rights Watch when stating a request or opinion instead of asserting it on his

First-party collection agency usually lasts for a period of months before the debt is turned over to a third-party collection agency. A creditor assigns accounts to a third-party collection agency for a fee. The fee differs depending on a wide variety of factors ranging from the collection agency that the creditor chooses to work with, to the number and type of accounts that will be submitted on a routine basis. The fee can be as simple as a flat fee per account submitted or a performance percentage fee on each amount that is collected. In some cases, it may be a combination of both. It is dependent upon the relationship that is agreed upon. As a collections manager Tangie overseeââ¬â¢s all activities related to the companyââ¬â¢s credit and collections. She is responsible for formulating, implementing, and maintaining credit and collections policies, monitoring collections and past due accounts, reporting on the activities of the accounts receivable department, and ensuring timely collection of customer accounts receivables. She also provides training, direction, and evaluation of credit and collections employees. In addition to overseeing the collection department staff, she tracks customer feedback through the review of incoming letters, emails, and phone calls and the analytical data collected through outside reporting agencies. She also identifies errors or glitches in collection procedures and recommends solutions to increase collections on delinquent accounts while ensuring customer satisfaction and retention. The Plan I have established a plan to keep the employees in Tangieââ¬â¢s department motivated and satisfied. Keeping employees motivated and satisfied are important elements of not only getting the most out of your employees, but also in retaining your best employees. The best employees are always in high demand, and will change companies if they are not kept motivated and satisfied at work. It doesnââ¬â¢t matter what you build, invent or sell; your organization canââ¬â¢t move forward without people. CEOs, company founders and managers the world over know that keeping the teams beneath them moving forward together in harmony means the difference between winning and dying. The plan that can be applied to Tangieââ¬â¢s department that would increase the motivation, satisfaction and performance would be to first, have the team members build ownership among themselves. They must feel as if they own the place and not just work here. Once of the principles of self-managed teams is to organize around a whole service or product. One way to inspire this feeling is to have each of the members become familiar with what the other members are doing, allowing them to bring their ideas for improvement to the table and have input in the entire process. If the roles are too specialized, have each of the members of the team exchange responsibilities often. This all makes them feel like ââ¬Å"itââ¬â¢s mineâ⬠, and most people, when itââ¬â¢s theirs, really donââ¬â¢t want to fail. Next, you must trust the employees to leave their comfort zones. This means to allow them to do more than one specific task, it will allow them to grow and become more confident in their abilities while making them feel more valuable to the organization. Even though as a manager it may feel like allowing individuals to try new things presents a risk to productivity or places workers outside of their established place, it heads off other issues. The bigger risk is having people get burnt out or bored. Then, is to keep the team informed; business leaders have a clearer perspective on the bigger picture than their employees do. Itââ¬â¢s really important to tell subordinates whatââ¬â¢s going on. What a manager may take for common knowledge about how things are going or what challenges are down the road, employees should be informed of. Spreading the intel lets everyone in on the lay of the land and at the same time strengthens the feeling among workers that they are an important asset to the organization. Then, is the fact that your employees are adults so treat them as such. This is also important when it comes to motivation and satisfaction in the organization. Employees need to be dealt with in a respectable manner. In any organization there is going to be bad news. It could have to do with the individual or the company as a whole but just remember to treat employees accordingly. As a manager, if you choose to keep people in the dark about trying times or issues, the fallout could be more serious than the issue itself. When people are left out, they tend to make things up. An important part of the plan is to remember that money matters, but not as much as you think. Compensation packages are a big deal when employees are hired, but once hired the motivation tends to go downhill. The motivation then comes from things like the challenge of the work, the purpose of the work, the opportunity to learn, and the opportunity to contribute. Last, is to reward and recognize employees if theyââ¬â¢ve done something truly outstanding. Instead of telling others that your employees are doing such a great job, take the time to bring a specific person into your office or write an email or note along with that personââ¬â¢s paycheck to let him know that his work is truly outstanding. Rewarding them with small gifts like tickets to a movie, a gift certificate to a grocery store or even highly wish for tickets to a sports game is a good reward. Reward employees with time off, you will be astounded to see how quickly your employees get to work when you offer to let them leave a little early or if you give them the option of coming to work a little late the next day.

Primary Education In The UK And Spain
Primary Education In The UK And Spain Primary Education is an important topic to be discussed and analysed, since it is the basis of our societys formation, being thus decisive for our childrens future. This essay is entitled Primary Education in the U.K. and Spain: a comparison and it focuses on explaining some of the main matters concerning both systems. It is first of all focused on explaining some topics related to primary education in the United Kingdom including two paragraphs. The first one a historical background, proves to be the base of todays structure which may help us clarify todays structure, which the topic of the second paragraph. This is followed by two clone paragraphs applied to Spanish primary education. The last two paragraphs concentrate on the use and importance of ICT in primary education in both systems. The essay is concluded establishing an overall comparison between both systems. According to Denis Haye in his book Primary Education: the Key Concepts, British primary education and its structure find its roots deep in history, in the middle ages. It has been stated by some historians that English education began in AD 597 with the establishment of the cathedral of Canterbury by St Augustine. In the end of the seventeenth century education belonged to the church which promoted Christian knowledge, by creating its own schools. At the same time there were pioneers such as Robert Raikes, Charles Gordon and the welsh Charles of Bala, who believed in a connection between social action and education. The first publicly funded schools appeared in the mid-nineteenth century and aimed to offer Christian education to poor children. From this time on, the control of education starts switching little by little from the church to the state. Furthermore, between 1846 and 1848 in Wales, the Welsh Education Committee and the Cambrian Society both evolving into national schools , were formed. In the nineteenth century it is important to highlight the education act of 1872, since it lead to many advances in primary education, not only affecting the labouring classes as was happening in other parts of the country. The 1944s education act was decisive because from this time on, education was free of charge and relied on voluntary provision. It is known by the introduction of three kinds of schools: grammar schools, modern schools and Technical schools. The year 1988, saw the introduction of the nation curriculum including a selection of subjects such as maths, science English and religious education. From 2010, teaching foreign languages is also a compulsory part of the curriculum. In order to explain the base of todays primary education in the UK, it is necessary to go back to the twentieth century, when there were many important changes in primary education. Among these, stands out the introduction of the national curriculum in English mainstream schools. In this author words, during the twentieth century, it was also thought to be decisive an agreement about the need for a general education for children up to the age of 11, this being followed by a subject-specific teaching up to the age of 16 and a selection of specialist subjects thereafter. Due to the national curriculum, from the beginning of the 21st century most primary schools in the UK currently accept children from 5 to 11 years old. As Denis states, there is also a tiny number of schools designated deemed middle (ages 8 to 12 or 9 to 13) and first when they educate children from 5 to 8 or 9. To explain todays structure it is also important to focus on the types of schools that can currently be found in the UK. As the Department of Education reports, they can be divided into 3 main groups: mainstream state schools, specialist schools, state schools with particular characteristics and independent schools. To the first group belong Community schools, which are often run by a local authority and aim to develop strong links with the local community, providing servicesà like childcare and adult learning classes. Trust schools as well as Voluntary-controlled and voluntary-aided schools are owed by a charitable foundation, which employs the staff and sets the admissions criteria. Academies, faith schools, city technology colleges, community and foundation special schools, grammar schools and maintained boarding schools can be found in the second group. The third group is formed by Independent schools which have their own admission policies and curriculum. Spanish primary education, as the rest of the developed nations, it finds its roots in the XIX century. Many factors can be identified as those which influenced the rise during this century of specifically educative establishments aiming to reach a growing proportion of the population. The Apparition of the national states is indeed the most notorious factor, since it puts the Old Regime to an end while at the same time instruction is seen as a mean reinforcing its unity. Thus, education is considered to be from this time on, a public affair that has to be organised and controlled by the state which regulates its legal and administrative processes. To understand the current Spanish primary education, it is important to focus on three relevant education laws, well-known for their impact on the system. The commonly referred as the Moyano Law was decreed in 1857 in a context of socio-economic crisis, This law consisted on a legislative initiative carried out by the politician Carlos Moy ano whose main aim was to improve the deplorable condition of education at that time, decreasing thus the analphabetism average in the country. Education was divided in two stages: elementary (6-12 years old) and superior (9-12). Primary education was compulsory until the age of 12 and free of charge for those who could not afford it. According to the web page State Univeristy.com, it also marked the foundation of privet schools in Spain at that time owned by the Catholic Church. Just one year after the 1944s British education act, the 1945s law was decreed in the historical context of post-war and in the ideological context of national Catholicism. Its main objective was to orientate the student in accordance with their aptitudes to the working life. Born in the context of democracy, the 1990s law of education aimed to impart an equal instruction in order to allow pupils to acquire basic cultural elements, to wit: oral expression, reading, writing and arithmetic calculi. It divided education into tree periods: the first stage (from6 to 8 years old), second (8-10) and third (10-12). To explain the structure of todays primary education in Spain, it is important to go back to the year 2006, when the fundamental law of education also known as LOE or Ley Organica de Educacià ³n was decreed. This law established a compulsory education from 6 to 16 year-old children. While in the UK children start their primary education at the age of 5, Spanish children start going to school at the age of 6. Also it is important to mention that most pupils attend pre-schools from 3 to 5 years of age. Most of these nursery schools in most cases belong to the same centre of education. According to the famous online encyclopedia known as Wikipedia, primary education in Spain can be divided into three cycles: the first cycle includes pupils from 6 to 7 years of age, the second 8-9 and the third 10 to 11. Focusing on the Spanish national curriculum, compulsory subjects are: Spanish language and Literature, Art, Mathematics, Physical Education, Natural and social sciences both included in a subject called Conocimiento Del Medio and English or French. Many state schools have an agreement with the British Council making the study of English compulsory from the age of 6. Although in the United Kingdom there a several types of schools, in Spain most of them can be grosso modo divided into three groups: public or state schools, privet schools or semi-privet schools also referred in Spanish as concertado schools. As happens in the UK, state schools are funded by the government and therefore they are free for those living in the country. These cannot be freely selected, as the children are allocated the closest school to their home. According to Maurice Hamlin in his web page practicalspain.com, semi-privet or concertado schools are similar to the Britishs grant maintained schools since they receive subsidies by the government being education thus, provided free of charge. Most of them are run by a religious order e.g. the Salesians of Don Bosco, and pupils usually wear un iforms. Privet and International schools in Spain are becoming more popular. According to the Article Living and Working in Spain they provide a more relaxed environment offering a wider range of subjects and an international approach. Another important aspect to be analysed, is the use of the information and communication technologies in British and Spanish Schools. According to the British Department of Education, information and communication technologies (ICT) in schools can improve the quality of teaching, learning and management in schools and so help raise standards. In order to evaluate the use of ITC in primary schools The Education and Training inspectorate published in 2002 a report in which some of the main strengths of the use of new technologies are highlighted. As this report states, integrating the ICT in the national curriculum supports both teaching and learning. The quality of planning for ICT is proved to be satisfactory or better in 70 % of the schools inspected and in most schools the quality of teaching and pupils experiences are proved to be satisfactory, including a wide range of ICT applications among which stands out the use of word processing. Learning to use Microsoft Words spell check, digital cameras, create an maintain a web page, sending a forwarding e-mails, burning a cd, as well as learning how to control multi-media and database software are indeed but a few other applications in schools. As this study proves, ICT has also a very positive reaction on children by increasing their motivation towards learning in general; as the report states children have high levels of interest and enthusiasm in their work in ICT being motivated by the inclusion of ICT in their lessons. It is a fact that there are an increasing number of schools that are incorporating ICT not only as a subject in the national curriculum but as a way to make the other lessons lighter and more amusing to children. According to an article written by Sophie Borland and published in the newspaper The Daily Mail there are even some schools in the UK who have decided to turn a P.E. lesson into a Wii class in order to motivate and boost their enthusiasm for sport. To do this, Borland says, the newly approved by Department of Health Wifit Plus is used in the class involving a variety of fineness activities. Even though this article received very positive reviews there are some people like the spokesman of the Department of Children, Schools and Families who states there is always a place for innovative exercises if they do not replace traditional ones. Another school in the UK, according to the education editor Graeme Paton, is to include the use of the so-called social network Twitter as pa rt of their curriculum. All children, the author states, will be taught how to use webcams, podcasts as well as blogs. Pupils in this school will be expected develop an understanding of different ways to communicate online. Improving keyboard skills, using websites such as the online dictionary Wikipedia and learning how to employ spell-checkers will also form part of the biggest overhaul of lessons for 20 years. As happens in the United Kingdom, Spanish new generation of children are marked by the information and communication technologies which are gaining each year a greater importance in the education policy. The inclusion of the ICT in Spanish education system finds its roots in the European initiative e-Europe which motivated the creation of the Special committee of study for the Development of the Information Society in Spain (CDSI) by the Ministry of Science and Technology. Some of the conclusion of the CDSI can be applied to education. According to this committee the use of the new technologies should be present in all subjects as part of the national curriculum and in the relationship between teachers and pupils and all the members of the educative community. The presence of ICT in Spanish primary schools can be clearly perceived in the autonomous community Extremadura which is considered to be a pioneer in this field. According to the secretary of ICT in the education polity of the autonomous government of Extremadura Junta de Extremadura, this region started the project of including the information and communication technologies in education in the year 1999, when the Strategic Plan for the development of technology in society was presented and the educational sector was considered to be the main pillar of that development. This moment marks the appearance of ICT in Extremaduran classrooms. What is probably the most outstanding fact is that, this region decided to develop free software equally configurable and adaptable. A new operative system called gnu/LinEx which would offer an enormous variety of applications in order to fulfill the necessities of all kind of users and a great diversity of tools for its use inside the classroom. Furthermore, in the academic year 2002/2003, an initiative was carried out in all Extremaduran high schools which consisted on transforming regular classrooms into technological classrooms by introducing a computer for each two s tudents. Also, todays schools in the region have at least one electronic blackboard, together with a projector, a computer and an interactive pad. The creation of the specific operative system LinEx must be adapted to a didactic and pedagogical extent. This is why a new variation of this operative system has been installed in all the schools of Extremadura. According to the autonomous communitys government LinEx Schools as it is called, offers the pupil an friendly and motivating environment adapted to their intellectual development. Together with LinEx, it is important to highlight the development of the educative platform Rayuela. As if it was a social network, this platform is an advanced system of information that allows a real-time communication between teachers and parents by using the Internet. It also has a database with allows all Extremenian students to have a single Digital Academic Record until they finish high school. Thus, teachers are able to access all the informatio n about the educative course of their pupils (calcifications, assistance and observances) in order to offer them an individualized treatment. To conclude this essay, I must say that as both educational systems belong to a globalised world and concretely to the European Union, they share indeed some similitudes and the two last paragraphs are an example of this statement. Among other minor differences British primary education probably differs from the Spanish one in what in my opinion, is its main strength: the diversity of schools offered which allows parents to have a greater choice. 2.500 words.

Motivation For Drowsiness Detection Information Technology Essay
Motivation For Drowsiness Detection Information Technology Essay Monitoring the drivers action while driving by examining the manoeuvred of the vehicle can be a very prominent task in order to enhance safety while driving. To differentiate between unintentional and intentional car steering wheel inputs, will be the main key element to be discovered, such as a sudden large steering input could indicate the drivers level of alertness. Almost all the statistics have identified driver drowsiness as a high priority vehicle safety issue. Drowsiness has been estimated to be involved in 10-40 per cent of crashes on motorways [5, 6]. Fall-asleep crashes are very serious in terms of injury severity and more likely to occur in sleep-deprived individuals [8]. Drowsiness influences mental alertness, decreasing an individuals capability to handle a vehicle safely and expanding the possibility of a human mistakes that could lead to deaths and injuries. Furthermore, it has been indicated to slow response time, decreases awareness, and impairs judgment. A drowsy driver is unable to predict when he or she will have an uncontrolled sleep onset [9]. There is an increased interest with respect to the design and advancement of computer controlled automotive applications to overcome those problems by enhancing safety to reduce accidents, increase traffic flow, and enhance comfort for drivers. This thesis presented a way to detect drowsiness in driver non intrusively by warning the drivers, preventing accidents and to improve safety on the motorways. This method is employing Support Vector Machine (SVM) to train the classifier by using steering wheel angle, distance to outside lane and acceleration as an input to the SVM. All the parameters extracted from vehicle parameter data collected in a driving simulator. With all the features, a SVM drowsiness detection model is constructed. ACKNOWLEDGEMENTS I would also like to extend my appreciation to Mr John Mellor Dr Ping Jiang for his assistance in educating, assisting and helping me on the preparation of this thesis and who has supported the work not just financially but also provided very valuable feedback and guiding ideas for the production of this thesis. Chapter 1 This chapter illustrates a general overview of this research. Background information related to the topic of drowsiness detection and support vector machine along with research objectives are introduced. Related literature is reviewed in this section, linking relevant topics to the research presented here. Finally, an outline of the thesis and a brief description on the contents of each chapter are also presented. Introduction The proposed non intrusive drowsiness warning system uses a integration technique comprise of vision sensor to obtain road information and steering wheel angle data logger. Both parameters are taken from road simulation experiment. The system is composed of three main processes; To obtain the road information by calculating the distance of the outside lanes from vision input and extracting the steering wheel angle data. These data are used for training and testing intentions during the modelling of the SVM. To give a proper warning to the driver to eliminate false alarm. It is most important that a drowsiness warning system guarantee safety and reliance. Therefore the system must reliably as well as estimate the driver vehicle state in order to give proper warning. It must also consider driving habits and intention of the driver to be of practical use. Research Aim Objectives The aim of this thesis is to contribute to the study of driver behaviour while driving, through the development and evaluation of a drowsiness driver model system. Non-intrusive is chosen as a method due to comfort to the drivers. The result from the research will be integrated to produce the systems that can be efficient in detecting the drowsiness level at an early stage by giving a warning to them about their lack of attention due to drowsiness or other factors. In other words, they can correct the behavior or stop driving when they in the drowsiness state. This system will need to be robust against model mismatch and disturbances and comfort constraints. The objective of this research is to identify the current drowsiness detection by investigating flexible methods for studying the relationships between drivers manoeuvre performances whiles the vehicle on the move and the physiological driver drowsiness states. This thesis paper outlines the design and development of a system that focuses on drivers drowsiness detection and prediction through the following methods:-. Monitoring the driver behaviour by observing the vehicle manoeuvre stability and performance. Validate and measure the progress by using Specific algorithm. Updating the current performance by comparing with the last action stored in system database. Warning the drivers if the behaviour beyond the thresholds. To increase the detection and its reliability of the prediction, the methods stated earlier will be used. Here we will employ machine learning methods to classify the data of actual human behaviour during drowsiness. This will be done by studying and evaluating the learning phase identification of a driver driving pattern. After that we will look to evaluate the parameters comprehensively. In the detection phase on-line model adaptive identification; model error classification; drowsiness alert model will be studied. By implement a control system mechanism that integrates human and machine for classification of the dynamic model for drowsiness detection using information from various sources for achieving a probabilistic best possible alert. Scope The scope of the thesis is defined as follows: The road manoeuvre will be restricted to simulation environment only. There are no obstacles in the road lane, and thus there is no collision-avoidance aspect to manoeuvre. It is assumed the vehicle will operate with a fix velocity range of 50km/h. Two main parameters will be an indictor for the system detection consists of distance to outside lane and steering wheel angle. Motivation for drowsiness detection. Driver drowsiness is a significant factor in the increasing number of accidents on todays roads and has been extensively accepted [2]. This proof has been verified by many researchers that have demonstrated ties between driver drowsiness and road accidents. Although it is hard to decide the exact number of accidents due to drowsiness, it is much likely to be underestimated. The above statement shows the significance of a research with the objective of reducing the dangers of accidents anticipated to drowsiness. So far, researchers have tried to model the behavior by creating links between drowsiness and certain indications related to the vehicle and to the driver [2,3,4]. Previous approaches to drowsiness detection primarily make pre-assumptions about the relevant behavior, focusing on blink rate, eye closure, and yawning [29,30]. The automobile business also has tried to build several systems to predict driver drowsiness but there are only a few commercial products available today[31]. The systems do not look at driver performance and overlook driver ability and characteristics. Naturally, most people would agree that different people drive differently. The system that being develop able to adapt to the changes of the drivers behaviour. Contributions The contributions of thesis research extend to five areas. The introduction of a fully integrated drowsiness warning system with specific algorithms to detect driver condition. The main contribution of this study is it contributes an algorithm of drowsiness driver detection and tracking which based on incorporation of vision and vehicle performance parameter. The implementation of support vector machine for robust and accurate drowsiness warning system. The input incorporation from vision and data logger provides an efficient method for detecting drowsiness driver under varying mode and road conditions. Consideration of various type of driver with various conditions in order to build the system. Software tool Support Vector Machine In the way classifying things Support Vector Machine is the modern technique in the field of machine learning and has been successfully used in many fields of application. The aim of this thesis is not to give a comprehensive demonstration about the theoretical background but to reveal the fundamental functionality to get an extensive understanding how SVMs work. The thesis also summaries what has to be considered when SVMs are applied, which fields of application exist and what the fields of researches nowadays are. The machine is a learning algorithm for performing classification and regression via a hyperplane in a large virtual feature space. For classification, the SVM is given a set of inputs called the training set, and attempts to automatically determine a hyperplane in feature space that separates these inputs into two classes. The hyperplane allows the machine to make an informed classification on a test vector where the true classification is unknown. Based on the assumption that the test vector and the training set are drawn from the same source, the SVM has predictable bounds on getting the classification of the test vector correct. For regression, the SVM similarly uses training vectors but derives a hyperplane-based function that can estimate a real valued function. One of the things that set SVMs apart from more traditional linear systems is their use of what is known as a kernel function. Kernels functions which allow the SVM to classify features that are nonlinear functions of the training vector attributes. While it performs this classification in a space of very high dimensionality (the feature space), it only requires computation in the smaller dimensional space of the training vectors (attribute space or input space). The other thing that sets SVMs apart is parametrically controlling the capacity of the SVM (its VC Dimension) to avoid underfitting and overfitting. Let take some example what if you do if you have given a collection of oranges and apples, and you being asked to differentiate between the two types of fruit? Within a second, everyone can immediately separate them based on how they look and feel. Although this problem of differentiating orange and apples does not look very complex, automating this process turns out to be fairly complex. What should be the basis for the decision to call an object orange, and another object apple? This problem is called classification in order to assign a new object to one of a set of classes, which are known already. The classifier which should perform this classification operation, is based on a set of example objects. This thesis will not focus on this classification problem though, but on the next problem, the problem of one-class classification. Here an object should be classified as a genuine object (orange or apple), or an outlier object (another type of fruit). The one-class classification problem differs in one essential aspect from the conventional classification problem. In one-class classification it is assumed that only information of one of the classes, the target class, is available. This means that just example objects of the target class can be used and that no information about the other class of outlier objects is present. The boundary between the two classes has to be estimated from data of only the normal, genuine class. The task is to define a boundary around the target class, such that it accepts as much of the target objects as possible, while it minimizes the chance of accepting outlier objects. MATLAB: MATLAB is a matrix-based numerical computing environment and programming language developed by The MathWorks. Simulink was used extensively for modelling, simulating, and analysing the drowsiness detection system. By using the Simulink application such as Hough Transform, Hough Lines and Kalman Filter blocks to create a lane detection and tracking algorithm. Thesis Outline Chapter 2: describes the literature review. Chapter 3: Definitions of variables associated with this particular approach for solving the problem are discussed. Chapter 4: Summarizes the results of this research and presents findings from the parametric study. Chapter 5: Finally, the conclusion of the research and recommendation on future research are provided in Appendix contains the major experiment files used to perform the simulation. Chapter 2.0: Literature Review The initial phase of this thesis was the preparation of a literature review. This review included literature from past research projects, conferences and journals on the drowsiness detection system. A comprehensive search was studied and has been reviewed to identify key studies, reports and researches initiative addressing drowsiness toward driving issues. It is attended to investigate the available knowledge in the field and to distinguish the most encouraging indicators of drowsiness drivers. Most of these methodologies have only been developed in the laboratory or have had a limited application on-road. In the current development of the drowsiness detection system, the possible techniques can be generally divided into the several categories. This category technique includes measures of: The drivers current state, especially relating to the eye and eyelid movements and physiological state changes. Driver performance, with a focus on the vehicles behaviour including lateral position and headway. A combination of the drivers current state and driver performance. We can conclude the methodology can be separated into two sections: Intrusive methods Electroencephalography Some researchers have looked at the use of EEG as a method for detecting drowsiness. Most of these studies have used EEG to verify the existence of drowsiness when other measures are being evaluated rather than as a fatigue-detection measure [12]. For example, a study by [13] demonstrated substantial relationships between an EEG algorithm for detecting fatigue and drowsiness under simulated conditions. The biggest disadvantage associated with EEG as an on-road drowsiness detection device is the difficulty in obtaining recordings under natural driving conditions; making it a slightly unrealistic option for the detection of drowsiness. In summary the transition from wakefulness to sleep can be described as a shift towards slower frequencies in the EEG. The process different between individuals but seems to be consistent within the individual [10, 11]. EEG is widely received as a good indicator of the transition between wakefulness and sleep as well as between the different sleep stages. When a driver gets drowsy a burst of alpha activity can often be seen in the central regions of the brain. An increase in alpha activity is thus the first sign of drowsiness. As the driver gets drowsier, alpha activity is replaced by theta activity. When delta activity occurs in the EEG the driver is no longer awake, this is an indicator of deep sleep [10]. Electrooculography Electrooculography is a method used for measuring the potential difference between the front and back of the eye ball. The EOG can therefore be used for detection of eye movements and blinks. The eye is a dipole with the positive cornea in the front and the negative retina in the back and the potential between cornea and retina lies in the range 0.4 1.0 mV. When the eyes are fixated straight ahead a steady baseline potential is measured by electrodes placed around the eyes. When moving the eyes a change in potential is detected as the poles come closer or farther away from the electrodes. The sign of the change depends on the direction of the movement [10]. EOG is measured by placing electrodes around the eyes. Usually silver-silver chloride electrodes are used as they show negligible drift and develop almost no polarization potentials. The electrodes should be placed as near the eyes as possible to maximize the measured potential. Problems with EOG measurement are artefacts that arise from muscle potentials and small electromagnetic disturbances that can be induced in the cables. To reduce the impedance between skin and electrode, the skin must be cleaned carefully before measurement and electrode paste should be used [10]. When measuring blinks related characteristics, the sampling frequency should be high (at least 500 Hz) as a high resolution is required to measure small differences in for example blink duration. DC recording is preferable, while filtering the low frequency components away makes the detection of long blinks difficult. One problem with DC recording however, is the risk of slow baseline drift, which makes it important to monitor the EOG signal and adjust for the drift during the measurement [14]. Non Intrusive methods PERCLOS PERCLOS (Percent Eye Closure) is a video-based method that measures eye closure. One of the strengths of PERCLOS is that attempts have been made to establish its validity as a fatigue detection device. Satisfactory relationships were obtained between eye closure and lapses in attention, providing some convergent evidence. When a measure correlates with other tests believed to measure the same construct of the systems ability to detect the current state of the driver. Furthermore, PERCLOS showed the clearest relationship with performance on a driving simulator in comparison to a number of other potential drowsiness detection devices including two electroencephalographic (EEG) algorithms, a head tracker device, and two wearable eye-blink monitors. PERCLOS is the most reliable and valid measure of a drivers alertness level between many drowsiness detection measures. According to a study performed by [17], drivers in an automobile simulator exhibit certain characteristics when drowsy, that can be easily observed in eye and facial changes [17]. Alert drivers were reported to have normal facial tone, and fast eye blinks with short ordinary glances. Drowsy drivers were reported to have decreased facial tone and slower eyelid. Gaze Direction Other potentially good fatigue parameters include various parameters that characterize the pupil movement, which relates to the driver gaze and awareness of the happenings in surroundings area. The movement of a persons pupil (gaze) may have the potential to indicate ones intention and mental condition. For example, for a driver, the nominal gaze is frontal. Looking at other directions for an extended period of time may indicate fatigue or inattention. In addition, when people are drowsy, their visual awareness cannot cover a wide enough area, concentrating on one direction. Hence, gaze (deliberate fixation) and saccade eye movement may contain information about the ones level of alertness. Many recent efforts [18, 19] produce a computer vision system that can extract various parameters in real time to characterize an eyelid movement, gaze, head movement, and facial expression. The major benefits of the visual measures are that they can be acquired non-intrusively. Lane Departure Warning Systems (LDWS). LDWS system is used to determine the position of the vehicle on the road. It is used either to warn the driver when the vehicle is on a white line (like rumble strips) or to predict when the driver is in danger of departing from the road, which rumbles strips cannot do [20]. A vehicle lateral position or lane departure situation occurs when the vehicle runs off the road, either on the left or on the right side of the road. This kind of situation is also called Run-Off-Road (ROR) or Single Vehicle Roadway Departure (SVRD). It is defined in [21] as the crashes where the first harmful event is the vehicle leaving the road high way. The simplest system is the rumble strip in which it alerts the driver when he is in a situation of lane departure in order to avoid ROR crashes. Rumble strips are areas of grooved pavement usually situated under the white lines of the road. When the vehicle drifts to the line, its tire hits a rumble strip, which vibrates the vehicle and makes a loud noise, alerting the driver to take a corrective action. This simple system is efficient since it has been shown to reduce the number of run off road crashes by 70% [22] but requires infrastructure modification. Another approach is to use a system inside the vehicle, which detects when the driver is in danger of departing from the road, and trigger an alarm in time for the driver to react. Steering wheel algorithm. Studies indicate that the steering wheel variability increases with the amount of drowsiness [23]. The steering movements also become larger and occur less often, and the lateral position variability increases as the driver gets drowsier. Also, the speed variability increases and the minimum distance to any lead vehicle decreases. The reaction time to any unexpected events also gets longer with increased drowsiness. Different studies have shown that there is a relationship between various steering related variables and the sleepiness of the driver. The steering related variables have the advantage that they are easy to measure since they require no camera or image processing. The drawback is that these variables are dependent upon the road curvature and are therefore mostly reliable on highways. [24] Other literature review has studied drowsiness detection by using steering angle rotation as an input to detect drowsiness by tracking steering angle by using a camera [25]. It tracks the steering wheel angle by using a single camera system put on inside the car. The approach is based on the modelling of the motion of the steering wheel, as it appears perceptively distorted by the point of view of the un-calibrated camera. The system has some disadvantages such as the steering image being block by the drivers head, light beam that confuses the feature detection algorithm and camera setup that not suitable for a portable application in monitoring steering angle analysis. Another drowsiness detection algorithm is based on the steering wheel. This algorithm works with three kinds of functions [26]: Time based functions (weighting functions developed from the time variations of the angle and the angular velocity), Frequency based functions (weighting functions developed from the variations in the power spectrum) Phase based functions (weighting functions developed from the variations in the angle plotted against the angular velocity). This algorithm is interesting because it proposes new detection ideas, such as the use of the phase diagram. The algorithm was tested on a special track with really drowsy drivers and it seemed to work pretty well. However, it has been created using data from drives on straight roads, so it may only work for straight roads, similar to motorways. Head position monitoring rotation. The advantage of computer vision techniques is that they are non-invasive, and thus are more amenable to use by the general public. There are some significant previous studies about drowsiness detection using computer vision techniques. Most of the published research on computer vision approaches to detection of drowsiness has focused on the analysis of blinks and head movements. It has been studied that these drivers exhibits certain physiological patterns that are expected and detectible. The standard head bobbing movement, where the drivers head drops and then rapidly pulls back upward is one of the patterns that is frequently displayed when an individual is becoming drowsy while seated in an upright position. Head movement like nodding or inclination is a good indicator of a drivers drowsiness or the onset of drowsiness [27]. It could also indicate ones attention. Head movement parameters such as head orientation, movement speed, frequency, etc. could potentially indicate ones level of attention. Finally, facial expression may also provide information about ones attention. For example, a typical facial expression that indicates the onset of drowsiness is yawning. Head monitoring tracking is a significant process for many vision-driven interactive user interfaces. The acquired position and orientation allow for pose determination and recognition of simple gestures such as nodding and head shaking. The stabilized image obtained by perspective de-warping of the facial image according to the acquired parameters is ideal for facial expression recognition [28] or face recognition applications. There are several commercial products capable of accurate and reliable 3D head position and orientation estimation. These are either based on magnetic sensors or on special markers placed on the face; both practices causing discomfort and limiting natural motion. Also, commercial systems based on gaze tracking employing infrared illumination do guarantee reliable detection of eye location, at the cost, however of restrictions placed on head position and orientation Head monitoring system developed by Advanced Safety Concepts, Inc. is the non-contact Proximity Array Sensing System (PASS), is an apparatus designed to record the x, y and z coordinates of the head at electronic rates using three electromagnetic fields. Its development is based on research that indicates a relationship between micro-motion of the head and impairment or drowsiness. It is hypothesized by ASC that changes in the X, Y, Z coordinates of the head may be an indicator of drowsiness onset, and that PASS may detect micro-sleeps based on different head movement patterns. Advanced Safety Concepts, Inc. reports that in laboratory tests, the PASS system has detected changes in head position as little as 0.0 l, while providing absolute XYZ resolution of head position to about 0.1. Disadvantages of current system. PERCLOS Disadvantages. PERCLOS stands for Percent Eye Closure. The technical definition is the percent of time a drivers eyes are closed. Sometimes a driver who is trying to stay awake can fall asleep with his eyes open, this is the disadvantage of PERCLOS. Another problem with this system is that the curve for warning is very steep at the end, which means that no warning is given at an early stage, and then the situation is very serious quickly. LDWS Disadvantages. Lane departure warning systems (LDWS) are system that currently being use to detect drowsiness. If the driver is drowsy, sooner or later the vehicle will drift to the side of the road and when it crosses the lane boundaries a warning signal is given to alert the driver. The problem with this system is that the warning signal is given every time the driver crosses the line, it does not take into consideration that the crossing could be intentional. TLC. Disadvantages. A commonly used variable in the warning algorithm of the LDWS is the Time to Line Crossing (TLC). The Time-to-Line Crossing (TLC), is the estimated time it takes for the vehicle to cross the line, which is based on a predicted path of the vehicle and the speed. The major problem with TLC is its computation in real time while driving on the road. Moreover, the computation is different on straight roads and on curve roads. EEG Disadvantages. To measure this signal while driving causes annoyance to the driver, because multiple sensors have to be attached to the driver. This can affect the driver so much that it changes the driving behaviour, which is not good at all in traffic safety research. Eye Detection Systems Disadvantages. The eye detection systems are good but not perfect, when the driver is wearing glasses there might be errors in the detection, which in some systems lead to false warnings. Sunglasses cause problems that almost none of the systems can deal with, which makes the inattention detection almost impossible when the driver is wearing sunglasses. Different ethnical people are another problem, the eyes of Asian people differ from European people, but most manufacturers claim that it should not be a problem. Research Approach Several elements have been taken into a consideration into designing the drowsiness detection system. Some researchers have already followed this route with encouraging results. By using several hypotheses and finding transformations in vehicle and driver behaviour, three based parameters will be tested for potential to predict the vehicle behaviour characteristic. In the investigation the signal will be recorded for a various driver, therefore data recorded each of the driver will were analyzed. It is important to notice that the data, of each individual driver has his own style of driving pattern. Diameter to Lane. As we all known Lane Departure Warning System can determine the position of the vehicle on the road. This position can then be used either to warn the driver when the vehicle is on a white line or to predict when the driver is in danger of departing from the road, [4]. The technique that we plan to use is to measures the distance between the car coordination toward the road lane border. It is a relevant suggestion because LDWS normally triggered when it reaches the lane. By the way it was too late to notice the drivers. Steering wheel angle. Studies indicate that the steering wheel variability increases with the amount of drowsiness [5]. The steering movements also become larger and occur less often, and the lateral position variability increases as the driver gets drowsier. Changes of velocity. More recent research demonstrated that speed variability was higher for sleep-deprived drivers than for control drivers [6].
If Slavery were Considered Moral :: Slavery
Describe the differences of this time period if slavery was considered "right". ISSUES TO UNDERSTAND CH. 14 1) The Compromise of 1850 was a dispute on whether or not Mexico (gained by US) would become a slave or free state. The northerners didn't want the 36'30' line to be moved to the Pacific and the southerners didn't want "free soilism" which would make Mexico a free state. Northerners gained from the Compromise California as a free state, New Mexico and Utah as likely future slave states, a favorable settlement of the New Mexico-Texas boundary, and the abolition of the slave trade in the District of Colombia. Southerners gained the burial of the Wilmot Proviso's persistence of new territories being free states, but the position of the free-soilers remained viable, for the compromise left open the question of whether Congress could prohibit slavery in territories outside the Mexican cession. Ãâ"How did the Compromise of 180 affect Southerners? 2) The Fugitive Slave Act affected the relationship between the two sides because often when a slave would leave and escape to the North, northerners wouldn't do anything to help get the slave back, in fact, in most incidents northerners tried to help keep slaves away from southerners if they escaped. South began to realize that opposition to slavery in the North was a threat to what they believed.-What was the Fugitive Slave Act and how did it hurt Southerners? 3) Uncle Tom's Cabin made many people convert to the belief that slavery was wrong and evil. It caused many people to view southerners as evil people. It also made northerners have sympathy for black slaves.-How did this book affect people's view of slavery? 4) The second party system collapsed because Whigs began to split into two groups: the American (know-nothing) Party and the Republican Party. Whigs also began to fall apart because of immigration. They thought immigration would not be important because they wouldn't be a big enough force for voting. So when the Whigs tried to get immigrant votes it just backfired and caused them to lose some ground with Protestant Whigs because the party had a hard anti-immigrant stand. Ãâ"What was the second party system? 5) The Nebraska-Kansas Act made many people angry because they thought that it was another territory that would be a slave state and not free. The idea of making it a state was to benefit Northerners because they were going to put a railroad system going through the Midwest to the pacific.

My Worldview: Answers to the Questions of Origin, Purpose ,and Destiny
A worldview is a personal insight about the reality and meaning of life. We all see ourselves through a particular set of beliefs, attitudes, and values. Each persons worldview develops overtime as he or she experiences new events and interacts with the world that surrounds them. A worldview provides the answers to oneââ¬â¢s origin, purpose, and destiny. Religion has a powerful influence on oneââ¬â¢s worldview. For the Christian, the filter for which all information is processed is shaped by the truths found in God. The truth of God cannot be ignored as God has revealed himself in many ways. The Scripture is one way that God reveals himself to humankind. The Bible is Godââ¬â¢s written revelation to humankind. There is a central theme that flows from the beginning to the end of the Bible. That theme is one of redemption and is key to my worldview. The first chapter of the Bible tells us, ââ¬Å" In the beginning God created the heavens and the earthâ⬠(Genesis 1:1 New International Version). Let us start here, in the beginning, as we start to form a worldview based on Biblical facts. The universe did not simply appear out of nothing. God is the Creator of the universe and all that exists in the universe; including humankind. Because God is the creator, he is self-existent and is therefore greater than anything that was created. God has a Creator-creature relationship with humankind. Through creation God revealed his divine nature to humankind. He is infallible, truthful, just, holy, omnipresence, omniscience, and omnipotent. The will of God speaks to the sovereign authority God has over creation. God is in control of everything that happens. God formed a covenant with creation in which all creation was promised eternal life in exchange for obedien... ...s from our sins and to save us from going to hell. Because God also gave us free will, we have to make the decision to spend eternity in heaven and we need to make that decision before it is too late. My worldview has been a long and personal journey. I have not always lived with the Spirit in my heart. I have always believed in God but have not always had a strong relationship with God. A walk through the Word of God has shown me that God has always had a plan and has always taken the first steps in having a relationship with me. I see through my worldview that the Bible lays out Godââ¬â¢s plan for my redemption. Through Godââ¬â¢s redemption I now have a worldview that supplies the answers to the questions of origin, purpose ,and destiny. Works Cited Zondervan NIV Study Bible. Fully rev. ed. Kenneth L.

Assessment method â⬠Written Questions Essay
Criteria 1.4: State why and when health and safety control equipment, identified by the principles of protection, should be used relating to types, purpose and limitations of each type, the work situation, occupational use and the general work environment, in relation to: ââ¬â Collective protective measures Fencing is used when access to the site needs to be prevented. They can be used to prevent access to the public and the workers making them use a designated entrance to site. This will make sure the members of the public cannot wander on to the site which could be dangerous for them or the workmen. Also making the workers go in through a designated entrance would allow everyone to be signed onto the site, so the foremen are aware of everyone who is on site. The main type of fencing is Harris fencing; this can be erected with ease and speed. It prevents access to the site but is only temporary and can be taken down as quickly as it can be put up. Harris fencing could also be blown over in a high wind. Harris fencing is not always necessary as existing fencing may already be in place. A garden fence, a garden wall or a hedgerow can be used to prevent access; they can be used on their own or in conjunction with fencing. Barriers are used to restrict access or to warn the workers of a da nger. These would be used throughout the job when appropriate. If there is a danger such as a trench that has been dug into the ground a barrier should be used to warnà people that it is there and also to stop someone from falling down into the trench. Different types of barrier include plastic barriers and bunting which is help up using metal pegs these are usually bright orange. The purpose of barriers is to restrict access and warn of dangers. They are only temporary and can be easily removed. Cones and warning tape could also be used as a barrier to restrict access to a certain area of the site. These are only temporary and can be easily removed. Signage comes in different colours which denote what type of information the sign contains. Signs can be used on fencing and barriers and can be in other areas of the site such as the site office. Blue signs contain mandatory information. These are things that everyone must do, they could be telling you what type of PPE you have to wear. Red signs are prohibition notices, telling you what you must not do such as smoke. Yellow and black signs contain warning information. The most common example of a warning sign is overhead cable signs. Green signs are Information signs which have information on things like first aid. These signs can be found in places like the site office or the site entrance. Also there is signage on packaging, these are COSHH signs and give information on how to handle that substance. ââ¬â Personal protective equipment (PPE) Hard hat ââ¬â A hard at is used when there is a danger of falling objects to protect the head from impact injuries or knocks. Some hard hats come with visors and ear defenders attached. The purpose of a hard had is to protect you from a head injury from objects falling from a scaffold, unprotect ends of a scaffold pole and other dangers. They must be warn when there is a scaffold on a site. Sometimes they can easily fall off your head but newer hard hats have a better fit. You can also get bump caps which are light weight hard hats. Ear Defenders- Ear defenders are used when there is a loud noise on site which could damage your ears. A loud noise could come from many different things on site, it could be you cutting down a brick or a block with a grinder, it could come from someone else using a piece of machinery. You can get ear plugs which you put into your ear which reduce the sound, these can only be used once. If you reuse them you can risk an infection by gettingà dirt into your ear. You can also get ear defenders which go over your ears which muffle a lot of the sound out. These can be used multiple times but may also not be compatible with other PPE such as a hard hat, although you can get ear defenders that work very well with a hard hat. Eye Protection ââ¬â Is used when there is a risk of dust getting into someoneââ¬â¢s eyes or an impact injury to the eye. There are different types of eye protection, safety goggles are made of a durable plastic and will stop both dust and flying debris from harming your eyes. Safety spectacles only protect your eyes from flying debris, these can be used when there is not a lot of dust for example cutting a brick with a bolster. Face masks are a rigid plastic visor that will protect your face from flying debris. They are commonly used with garden equipment like chainsaws and strimmerââ¬â¢s. They will not protect you from fine dust particles. Gloves ââ¬â Gloves are needed when there is a risk of damaging your hands or getting a chemical on them. Gloves differ in design, material and thickness. The correct glove should be chosen for the job after taking into account the possible risks. There are many different types of glove, from lighter material gloves which would be suitable if you are doing brickwork to heavier gloves that could be coated in different substances to give resistance to chemicals. You must also think about if you are going to need gloves that will protect your hands from cuts if you are doing a job and you are handling something that is sharp. Gloves will only have a certain lifespan as they will degrade through ware and tare or through contact with a chemical substance. Gloves must fit the user well as not to hinder his ability to work well and also his dexterity which could make him more likely to drop something. Safety boots- Most building sites will require you to always wear safety boots. Safety boots have a steel toe cap and a very tough sole. This will give the wearer protection from falling objects and also from standing on nails and other things. They also provide a sole with plenty of grip to help prevent slips. You can also get wellington boots that have steel toe caps which also keep your feet dry. ââ¬â Respiratory protective equipment (RPE) Respiratory protective equipment is used to prevent a worker from breathing in dust or fumes that may be hazardous. There are various types but the most commonly used type of RPE is a dust mask. These are light weight and comfortable and easy to fit. However, they will not offer any protection from toxic dust or fumes. Most dust masks are only effective for a short period and then they need replacing. Respirators have removable filters, which can be replaced. You can get different filters which do different jobs, some protect the user from toxic dust and some protect the user from fumes. Also you can get respirators which cover the whole face which provide more protection. If you are working in an area with low oxygen you should choose breathing apparatus with an air supply. You must ensure that the dust mask is correct for the job and provides the appropriate protection. You also must ensure that the mask is a good fit to the person who is wearing it. A poor fit will result in a poor seal allowing dust and fumes to get in. ââ¬â Local exhaust ventilation (LEV). Exposure to dust and to fumes can be harmful to peopleââ¬â¢s health. It can cause asthma, lung scaring and cancer. Therefore local exhaust ventilation systems are put in place to extract the airborne dust and fumes. There are different types of LEV and care must be taken to choose the most effective type for a particular job or machine. Most LEV systems simply suck the dust and fumes out of the air before they reach a worker. Some of them will also have a hood fitted which will help contain the dust and fumes as they are being sucked away. Water can stop dust from taking to the air in the first place, on some tools you can fit a water supply, such as a grinder where the blade is kept wet while you are cutting to keep the dust down. Sometimes just opening windows and doors will allow the dust to escape and clear the air. . Criteria 1.5: State how the health and safety control equipment relevant to the work should be used in accordance with the given instructions. Collective protective measures should be installed and used only by peopleà who have received adequate information, instruction and training. This will help prevent something like a Harris fence from blowing down in a wind because it wasnââ¬â¢t properly secured. The signage would have to be put up correctly to avoid a mistake being made so this would have to be done by someone who knows all the correct information. PPE should be in good condition and be well looked after by the user. The correct PPE should be chosen and correctly worn for each job, also you should ensure the PPE is compatible eg. Does the hard hat stop you from being able to wear your ear defenders? The PPE that is worn should be decided after thinking about the possible hazards. RPE used should be suitable to the job at hand, the user needs to think about if they need protection from toxic dust, fumes or if there will be a short supply in oxygen. Choosing the right mask is the first step and making sure it is a correct fit is the second. Fit testing is the best way to make sure a mask fits you properly, this should be carried out by someone who is qualified. Facial hair could stop you being able to get a tight seal and causing contaminated air to seep in. You should regularly replace filters on your mask and always check the correct filter for the job is fitted. You should store your mask in a clean, dust free area. LEV that is needed will vary depending on the task that you are doing. If you are sweeping a room indoors opening the doors and windows will allow most of the dust to escape. If you are using a grinder to cut a block or a piece of slate you could pour water on to it or add a water supply to keep the dust down. You could also do it outside. If you worked in joinery you could get a reputable LEV supplier to advise you on the best LEV system to ventilate your machines. Employees should be knowledgeable in how to use LEV. Criteria 1.6: State which types of health, safety and welfare legislation, notices and warning signs are relevant to the occupational area and associated equipment. The Health and safety Law poster should be posted up somewhere, this could beà in the site office, with the name of the trained first aider on it. There will be signage in green which are information signs. Such as a first aid sign. Blue signs tell people what they must do while on site. It could be information on what type of PPE must be worn. Red signs are probation signs telling people things they must not do, this could be no smoking signs or a no entry except to authorised personal sign. Yellow signs are warning signs. They warn people of dangers that they need to be aware off. This could be a sign warning you of overhead cables or a sign warning you that there is heavy plant machinery operating on site. There will be signs on machinery and power tools saying what items of PPE need to be worn while operating them. Signs will be on the packaging of harmful substances stating what PPE should be worn and what precautions should take place when using them. There will also be COSHH signs on the bottle or packaging of many different substances. These will tell the user what precautions they need to take while handling the substance or what they have to do if there is a chemical spill and how to neutralize it. Criteria 1.7: State why health, safety and welfare legislation, notices and warning signs are relevant to the occupational area. They are there to protect the work force from hazards and the dangers by informing people that these hazards and dangers exist, keeping people safe. They are also relevant because the signs inform people of what safety measures they need to take eg. PPE. Health and safety procedures and locations of things like the first aid office are and also the name of the trained first aider on signs. Criteria 1.8: State how to comply with control measures that have been identified by risk assessments and safe systems of work. The information and control measures that have been identified by risk assessments will be made available to everyone to read. You can read the mission statement which is that plan of action or you could be told verbally. You must follow these orders and work in the way that is instructed. Also there is information on machinery and tools, which will instruct you on how to work in a safe manner. COSHH signs on substances must also be followed to work in a safe way. Criteria 2.2: List typical hazards associated with the work environment and occupational area in relation to resources, substances, asbestos, equipment, obstructions, storage, services and work activities. Resources can become a hazard if they are improperly stacked. Materials such as bricks and blocks must be stacked in a safe and stable way, eg. Not too high. Care must be taken when moving resources. MHO (manual handling operations) need to be implied properly to make sure all lifting is done safely. Substances such as cement, lime and other chemicals and solvents can damage skin causing burns, dermatitis and other skin problems. Some chemicals and solvents could potentially present a fire risk so must be stored in a suitable way. Asbestos is found in lots of older buildings. It is at its most dangerous when it is disturbed. The fibres are inhaled and can cause severe damage to the lungs and death. When discovered asbestos should only be removed by a licensed contractor. Equipment can cause hazards if used improperly. Cutting tools and saws can be dangerous because you could cut of a finger or something worse. Some equipment can be loud enough to damage your ears. Some tools which produce a lot of vibration such as a breaker can cause white finger. Obstructions are a hazard because people can trip over them, also if they are blocking a fire escape it could be dangerous. If things are not stored correctly they could be unstable and fall over and hurt someone. Also certain materials must be stored under specific condition. Some materials present a fire risk. Care must be taken not to damage any services. If you are digging and you hit a gas or electric main it could be potentially dangerous. They should have warning tape above them but this is not always the case. Also if you are improperly trained you could be electrocuted if you attempt electrical work. Some work activities present a risk such as climbing ladders and work on a roof or scaffold. Also when machinery such as diggers are on site you must be careful. Criteria 2.3: List the current Health and Safety Executive top ten safety risks. Fall off ladder Fall through roof Lifting operations Struck by plant Overturning plant fall from scaffold Fall through an internal void Asphyxiation poisoning Crushed by falling excavation MEWP crushing entrapment Criteria 2.4: List the current Health and Safety Executive top five health risks. Exposure to asbestos Exposure to silica Manual handling Exposure to excessive noise Exposure to excessive vibration Criteria 2.5: State how changing circumstances within the workplace could cause hazards. If things change and not everyone is aware of these changes then people could get injured. For example if a hand rail is removed on a scaffold someone could fall off. A newly dug trench could become a hazard if someone who didnââ¬â¢t know it was there went near it then they could fall in, this could become more dangerous if metal pegs have been driven into the ground. Criteria 2.6: State the methods used for reporting changed circumstances, hazards and incidents in the workplace. Reporting change in circumstances and hazards can be done at a tool box talk, or you could bring them up as soon as they arise to the site manager and to the other workers. Incidents at work including injury and death should be reported. There are regulations in place (RIDDOR) making sure these things are reported. Accidents should be recorded in the accident book with information about the incident, where it took place and the date. If an accident causes someone to have an injury leaving them unable to work for more than three days they must inform the HSE. Criteria 3.6: State the organisational policies and procedures for health, safety and welfare, in relation to: ââ¬â Dealing with accidents and emergencies associated with the work and environment The HSE try to reduce the number of accidents and emergencies that occur in the work place. They also tell people what types of injury should be reported and how to report them. ââ¬â Methods of receiving or sourcing information The HSE has a website that is very informative for both employers and employees on many things such as a COSHH and MHO. You can also request advice from them. You could also read the Health And Safety At Work Act (HASAWA 1974). ââ¬â Reporting The HSE has regulations set in place called the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR). These regs make sure that everything is properly reported. ââ¬â Stopping work The HSE sends inspectors onto sites and he is able to make people stop work while something that could be a hazard is made safe again. ââ¬â Evacuation The HSE can send inspector on site and if he is not happy with what he sees he is able to close down the site by providing a prohibition notice. He will tell them how to make the site safe and what needs to be done to get it up and running again safely. ââ¬â Fire risks and safe exit procedures Employers must carry out a fire safety risk assessment and keep it up to date. They also need to ensure that adequate and appropriate fire safety measures are in place to minimise the risk of injury or loss of life in the event of a fire. ââ¬â Consultation and feedback. Tool box talks are carried out so that people can give instructions to others and also for people to give feedback on possible hazards such as a scaffolding has being altered. Criteria 3.7: State the appropriate types of fire extinguishers relevant to the work. Water, Dry powder, Foam and CO2. Criteria 3.8: State how and when the different types of fire extinguishers are used in accordance with legislation and official guidance. Not all fire extinguishers are suitable for putting out all types of fire. For example if you spray water on an electric fire it could make it a lot worse. Below is a list of what types of extinguisher is suitable for what type of fire. Water ââ¬â Paper , Wood, Textiles, Fabric Dry powder ââ¬â Paper, wood textiles and fabric. Flammable liquids. Flammable gases. Oils and fats. Electrical hazard. Foam ââ¬â Paper, wood textiles and fabric. Flammable gases. Oils and fats. CO2 ââ¬â Flammable liquids. Flammable gases. Oils and fats.
