Locke and Descartes source of knowledge - Essay Example For this reason, the theory holds that metaphysics, ethics, and math principles are fundamentally true and that physical evidence and proof are not needed to ascertain knowledge. Due to this belief, the rationalism theory is in direct opposition to empiricism. Empiricism, of which Locke is an integral proponent, contends that knowledge can only be obtained via the experience of sense. It emphasizes that evidence and experience, particularly the experience of sense, plays a more fundamental role in idea formation than traditions and innate ideas (Scheibe & Falkenburg 2011). The theory also contends that these traditions also arise due to prior experience through the senses. The theory emphasizes evidence, contending that all theories and hypotheses need to be tested against natural world observations and not simply relying on intuition or reasoning. The empirical theory is a better theory in discussing the source of knowledge because all that man knows has its basis on experience, whi le innate knowledge can be corrected with time following observation. Comparison Locke’s notion in the empiricism theory of an idea was borrowed from, the discussions by Descartes. According to Locke, the mind is the immediate object of understanding, thought, or perception by the mind (Scheibe & Falkenburg 2011). This is similar to what Descartes considers an idea to be, contending that it is what the mind can perceive immediately. Locke also discusses external object qualities, differentiating between secondary and primary qualities. Secondary qualities are explained as those, which are absent in the objects, instead being sensed, or perceived, while primary qualities cannot be separated at any time from the object. This is also similar to Descartes’ distinction using the candle. According to him, one can perceive the duration, substance, and shape of the candle but cannot clearly perceive sound and color, corresponding to primary and secondary qualities by Locke res pectively (Scheibe & Falkenburg 2011). Both Locke and Descartes contend that man is different from other animals and machines. According to Descartes, this is because machines are unable to use signals or words to declare what they know to other machines (Scheibe & Falkenburg 2011). In addition, animals do not have any reasoning in interpreting knowledge. Locke, similarly, claims that animals cannot abstract or come up with general ideas because they cannot utilize words. In their arguments, it is clear to see that they believe animals have no use for knowledge or ideas. Locke and Descartes also discuss the role of free will in gaining knowledge, considering that man’s will can remain free and be directed, as well as the fact that free will in gathering knowledge, being both free and directed, is consistent with man’s ability to err in his ways (Scheibe & Falkenburg 2011). Descartes contends that when a person is inclined to lean to one side, he possesses more free wil l. In addition, he also argues that free will is greater than intellect and knowledge. Locke builds on these arguments by contending that the determination of man by his free will does not restrain his liberty, while also arguing that bad judgments from available knowledge leads to bad choices. Contrast Descartes believes that knowledge

Saving Private Ryan Critique Essay The visual and the realistic arts in Spielberg’s best ever The critics all over the world with their holistic approach endeavor to find the pros and cons of a 3 hour classic masterpiece directed and created by the gods of the theatrical arts. The modern world tends to be sufficed by the major events and their results in History but no one understands that texts are just one form of expression. As actions speak louder than words, Steven Spielberg in his 1998 realistic and heart-pounding â€Å"Saving Private Ryan† portrayed the most deadly and the biggest invasion campaign in American history- Normandy and D Day campaign. The realistic and graphic effects of this campaign made this the best movie scene from all of the Spielberg’s classics. Spielberg’s will to create a movie which soon became the voice and representation of the millions of gladiators who lost their lives in this tragic war for peace and democracy as coined by Roosevelt showed his wish to show the veracity of the war and the literal sensitivity of the soldiers. The setting of the war scenes is so popular as the famous PC game Medal of Honor took their exact battle setting to give their gamers a chance to feel the war setting. These visual effects of the movie are enough to quell the rising viewpoints of the discrete historians on the issue of World War two and Spielberg’s realistic approach corroborates the fact that US had to undergo through copious hindrances in order to be victorious. The one fact that makes this classical war movie as his best ever is that his previous thriller and fictional masterpieces like Jurassic park had the ability to amaze and enthrall the audiences but in this case the story and the plot is set in perfectly, to appeal to their inner emotions and is enough to give rise to a patriotic feeling similar to the 85’s majestic Rocky IV which was set in the stage of cold war. The first ten minutes of the movie is built up emotionally as first a war veteran brings his family to the American cemetery which is like a prologue to an emotionally eye-catching story. Spielberg’s realism acts here as an evidence to the genuine war situation as history cannot be trusted through words but can only be trusted and felt through visuals. The plot of the movie is first set in a boat as forty men reach a shore and are exterminated in a matter of seconds which shows the intent to create a psychological effect on the minds of their audiences. Other monumental scenes are when Private Caparzo takes charge of a German girl from a German family in order to protect her. Scenes like these are illustrated to depict the intervensionalist side of US for a paternalistic cause similar to their control of Philippines. Spielberg’s idea of risking lives of eight men for one man has overturned the idea of social Darwinism. As social Darwinism promotes the idea of â€Å"survival of the fittest† that same idea is applied here as, Private Ryan’s survival in the war should be dependent on his fitness but instead the fitness of eight men are put on the line for his survival. However, putting our superficial analytical approach beside and using our holistic approach, its quite evident that Spielberg tries to make this war look like all American as he ignored the contributions of other nations in the D Day landing on the Omaha beach specifically. On the other hand, Spielberg’s best ever can also be criticized on the basis of violence as we get to see handless and legless soldiers which are enough to call this an adult movie. Spielberg’s classic realistic masterpiece can be juxtaposed with other war epics like â€Å"Inglorious Basterds†, â€Å"Valkyrie† and â€Å"Enemy Behind the lines† but â€Å"Saving Private Ryan† is one step ahead of them because of its realistic, graphic and non-fictional approach.

My Teaching Philosophy :: Essays Papers

My Teaching Philosophy Why do you want to be a teacher?This is a question I am frequently asked by rich relatives considering my choice from a monetary perspective; by my grandparents who both taught in the Bronx for 30 years; and most frequently by myself.Why do I want to teach?Why have I decided on history and social studies? In all honesty there have been many different answers to that question and the answer has changed three times since the start of this paragraph.I suppose part of being young is inconsistency.I am no different.But understanding these differences and understanding people is the key.I think I have a gift to see inside people and to help them see inside themselves.Right now there are three main reasons why I have chosen teaching history to by my life long profession, or at least until I have a mid-life crisis.These reasons are as follows: passion, ability and, no matter how clichà ©, the desire to make a difference. Since I was a child I have always been fascinated with history.I could watch the History and Discovery channels for hours. I had read the complete works of Jane Austin by the end of middle school.I used to go to the local museum and wander around for hours.In the second grade we took a field trip to see the Bill of Rights, which was on tour for its 200th birthday.Honestly, I remember very little of the actual document itself, but I will never forget the feeling.I knew it was important, because my teacher told so, and I know the awe it inspired in people.I think that is where this passion began.I received the Civil War documentary by Ken Burns on my tenth birthday and went to the Tower of London on my thirteenth.What started as awe has become my passion. What will this passion mean to my students you may ask?My father is a Roman Catholic from the Netherlands.My mother is a Jewish girl from Brooklyn.They met in a sheep field in Israel.I am a child of divorce and have a crease in my nose.The point is that I have a story.This story is more important than I can say.To know my story is know where I come from.This story, the story of my students, history is my passion.We are living it and breathing it.We are history.In my classroom I want to teach my students to care about who they are and where they come from.

Localism and Hoover’s views on goverment

Localism- the policy whereby problems could best be solved at local and state levels. Reconstruction finance corporation- urged by hoover to be passed; gave more than a billion dollars of government loans to railroads and large businesses trickle-down economics- theory held that money poured into the top of the economic pyramid will trickle down to the base Bonus Army.How did Hoover’s views on government influence his response to the depression? While not believing in charity by the government, Hoover did try an dhelp the economic mess that began during his administration. He gave much of his money to charity and encourage Americans to do the same. He broke with republicans and did away with the taxes that had been placed on citizens during the Coolidge administration. He thought that would allow for more income being spent to help the economy rebound. He spent $500 million a year on public works and government programs to build or improve government properties.The most famous was the Hoover (Boulder) Dam. Congress established the Reconstruction finance corporation (continued by FDR) which created an agency to help banks, railroads, and other key businesses to stay in business thus helping the economy. All of these things could not stem the tide of the economic collapse. Hoover believed in a balanced budget and not pumping government money into the economy. He believed in rugged individualism, and relied on the individual, the churches and private charities, and the state governments to handle most of the economic help that was needed.What facts show that Hoover’s policies to reverse the depression failed? Hoover left office with the economy at the depths of an unprecedented depression & with 25% of the labor force unemployed. To many out of work americans, the president became a symbol of failure. Some people balmed capitalism, while others questioned the responsiveness of democracy. Many believed the American system was due for an overhaul. Busi nesses often did not use the loans they recieved to hire more workers.4. How did MacArthur’s tactics in removing the Bonus Army affect Hoover’s political future?President Hoover ordered MacArthur to â€Å"surround the affected area and clear it without delay.† MacArthur brought up troops and tanks from Fort Myer, Fort Meade, Fort Washington and Fort Howard. After the bonus seekers refused to leave, Hoover eventually ordered the army to forcibly remove them. The marchers collected in a single area and Hoover ordered the siege stopped, but Mac Arthur continued the assault. Eventually 55 were injured, one woman miscarried and one man who was already sick died. Roosevelt milked the event for all its worth during the campaign of 1932 and suggested that he would have done better. (The Marchers were not actually owed any money, but hoped to pressure the government into giving them an advance on tehir pension.)

successful marriages essays

successful marriages essays For any marriage to be successful there are certain changes a man and woman have to make. They have to be flexible and open and ready for new experiences and ways of living. Marriages can be successful or unsuccessful based on many different aspects of it. Four important concepts that are definitely part of the whole marriage life are: children, conflict resolution, outside influences, and communication. Children may be the biggest change to a married couple. From going from just the two people, doing whatever they want, whenever they want, to staying home and taking on the responsibilities of taking care of children is a big step. Gone is the freedom of leaving at the spur of the moment to catch that new movie that just came out, eating what they want, when they want, buying whatever they want, and sleeping in until noon. The average number of children for parents completing my survey was two. Everyone knows that raising children is very stressful, but because of the different ages of the parents, and the children, I could not get facts on which years were the toughest. Most parents whose kids are well into their 20s or so, say that the most stressful years for them were the teenage years. Children that are toddlers are said to be less stressful then when they were infants. It varies for everyone, and from my surveys I got no facts, just opinions. Children are a big responsibility and cause a lot of stress for parents. Out of 30 people, 96% say that their children have been a cause for an argument at least one time throughout their marriage. This could occur for many reasons; one being that it is very expensive to raise children and parents would have to agree on what is necessary for their children to have or things that are just nice to have. They must agree to what their priorities are a nd each partner would have to adjust. Also parents might feel differently about ways of disciplining their children, wh...

Best Careers for Your Personality Type

Best Careers for Your Personality Type As you hunt for a job, some things are crucially important: your resume and experience, your skills, and your interview game are all major parts. But don’t forget another huge element: your personality. Your personality is who you are, both on the job and off of it, and it’s majorly important to understand who you are before you pick a career. After all, you want to find a career path that makes you feel happy and productive, not one that fills you with dread because you feel like you’re constantly pulled out of your comfort zone. (A little discomfort can be good and galvanizing for your career as you try new things. Too much just makes you miserable.) If you haven’t already, take the Myers-Briggs Type Indicator (MBTI) personality assessment, which is the gold standard in personality tests. It’s a little more intense than the â€Å"Which Member of The Stranger Things Cast Are You?† quiz you just took on Facebook, but worth it to get a handle on what your personality and motivations are.

Clinical Biochemistry Essay Questions Example | Topics and Well Written Essays - 500 words

Clinical Biochemistry Questions - Essay Example s disease is an autoimmune disorder in which certain antibodies are developed in the body against the thyroid gland which includes thyroid stimulating immunoglobulin (TSI), thyroid growth stimulating immunoglobulin (TGI) and TSH binding inhibitor immunoglobulin (TBII). The TSI antibodies bind to the receptors on the thyroid gland where under normal conditions TSH binds and stimulate the secretion of the thyroid hormone. While bound to the receptor to block the effect of TSH they actually lead to the increased secretion of the thyroid hormone. Because of the increased thyroid hormone low levels of TSH hormone are found in the blood. This results in hyperthyroidism with an enlarged thyroid gland which leads to protrusion of the eyeball, dermopathy and high basal metabolic rates. Hashimotos disease is also an autoimmune disorder which leads to destruction of the thyroid epithelial cells. CD8+ cytotoxic T cells and CD4+ T cells act against the gland leading to destruction of cells. Other antibodies against the thyroid include anti-TSH receptor antibodies, antithyroglobulin and antithyroid peroxidase. These lead to inflammation of the gland followed by wear out of cells. Hypothyroidism is the result which leads to enlargement of the gland. The basal metabolic rate drops and bradycardia, weight gain and somnolence are observed. Levels of the thyroid hormones, TSH, antibodies and basal metabolic rate (BMR) are checked in both the conditions. In graves disease thyroid hormone levels are high, TSH levels are low, BMR is high and antibodies specific for this disease are seen. In hashimotos disease the levels of thyroid hormones are low, TSH levels are high, BMR is low and the antibodies specific for this disease are found in the blood. There are four types of diabetes mellitus. Type 1 is known as insulin dependent diabetes mellitus, type 2 is referred to as non insulin dependent diabetes mellitus, the third type is

How might a large multinational clothing retailer ensure its workers Essay

How might a large multinational clothing retailer ensure its workers and its suppliers are acting ethically at all times in all the countries in which it operates - Essay Example Formulation of the special code of ethics would demonstrate sensitivity of the corporation to the local traditions. The companywide code of conduct should be supplemented by the internal business units of the corporation. Formulation of the special code of ethics should be a teamwork effort by the different functional areas of the corporation. â€Å"Enlisting the support of these local functions is important in shaping acceptable policies and dispelling notions that people at the home office dictate standards of behavior without respecting cultural differences† (LRN, 2007, p. 2). Top management assumes great responsibility for developing ethically responsible culture in multinational corporations. They should frequently conduct meetings to identify any lapses and temptations of unethical business conduct by the employees (Godiwalla, 2012). Multinational corporations should have an efficient communication and reporting system in place to timely identify and control ethical

Aging population in Japan Research Paper Example | Topics and Well Written Essays - 750 words

Aging population in Japan - Research Paper Example Despite the challenges, the aging population seems to create new opportunities because people will have longer healthier lives hence extended working years besides different capacities and needs (Lutz 34). The key to survival depends on adaptation on individual, organisational and societal levels. Japan is facing the population-aging crisis now. It is a resource-poor island hence changes in population size and structure tends to present a serious problem. Japan faced a problem of a large not-working population until the 1950s. From 1600-1868, the Edo period, Japan opted to hold down its population through extremely desperate means such as infanticide as well as negligence of the old people (Coulmas 5). Towards late 19 century, the population rose and it was unlikely that japan would ever face a shortage of births. However, that is what Japan is experiencing and has experienced over a couple of past decades. Over the last half century, death rates have reduced and the life span has increased by about 30 years. For women, life expectancy is currently at 82 whereas for men it is 76 (Uhlenberg 134). The number of those aged 65 and above was 14% of the population in 1994 and by the 2010; Japan was among the leading in the world in this measure. In Japan, people in their seventies and eighties are prevalent and even centenarians have increased in number. The difference in population structure is due to factors such as fertility and mortality(Coulmas 25).Women in Japan are no longer in a hurry to get married like in previous generations and when they marry, they sire fewer children. In Japan, unmarried women rarely have babies hence the slow rate of marriages contributes to the decreased young population. Women in japan have also opted on continuing with their education to get better job opportunities compared to those of earlier years. In addition, unmarried men are more than unmarried women hence

Discuss Nathanael Greene's Southern campaign. Why do some historians Essay

Discuss Nathanael Greene's Southern campaign. Why do some historians view Greene as being second only to Washington in importance in winning the war - Essay Example Greene was handed the responsibility of leading the then weak Revolutionary southern army that had already been led by three commanders who failed in their duties (Golway, 2005). He was given the duty of commanding the war against the British occupation of the south. With a small and poorly trained army, he was up against a more established and experienced British army. With the awareness that his troops were not able to win large and decisive wars, he planned brief and sudden attacks against the prominent British army. He took a bold step to divide his army into smaller groups, forcing the British troops to do the same (Tucker, 2009). He then ordered the Continental army to retreat, and the British, without realizing the tactic used against them, followed the Continental army. This drove the British army further away from their supply base, making them weaker and eventually losing the battle (Tucker, 2009). Some historians view Greene as second to Washington in the importance of winning the war because he was appointed by Washington and took orders from him (Carbone, 2008). He also succeeded where three other commanders had failed. In the same way like Washington, he was gifted with the ability to use small means to a significant advantage (Carbone,

Developing a Conservation Plan for Pinery Park in Ontario, Canada Essay

Developing a Conservation Plan for Pinery Park in Ontario, Canada - Essay Example The management plan of the park should consider the region that surround the park in general. The overall effort of the management will be of future benefit to the parks and the surrounding environment as a whole. Proper management of the park will highly contribute to the increase in the social tact among the local programs. The realization of conservation goals for Pinery Park requires strategic plans for easier management of the whole landscape that includes the areas that are set aside for either production or protection. Reserves alone are not sufficient for life conservation but they are the real basis mostly on which national plans are constructed on. Reserves have two main roles. They should be the real sample or either they should represent the biodiversity of every section. On the other hand they should detach this biodiversity from any of the processes that intimidate its diligence. Existing reserve systems like the PINERY Park contains prejudiced sample of biodiversity, u sually that of remote places and other areas that are unsuitable for viable activities. A more systematic approach to locating and designing reserves has been evolving and this approach will need to be implemented if a large proportion of today's biodiversity is to exist in a future of increasing numbers of people and their demands on natural resources. The extent to which the park will achieve and fulfill its goals is when they meet two main objectives that will lead them to their success the objectives are a long-lasting goal and representativeness these are the two main keys that are needed for full variety of biodiversity. The Pinery park management needs to set 1.2million dollars. The money should be allocated to a control program that will see different species in the park that require different amounts of space to complete their life cycle. A finding of the most reserves in the world clearly indicates that most of the worlds well known reserves contain very rear species. that would not persevere as inhabitants even for a single generation if in any case or to some extent they became secluded like for the oak tree that is found in the park. This tree is not found in most parts of the world the demand of the products is endangering the species making it rear in the forests. Many other reserves, without supplementation by unreserved habitat, would be likely to lose species in the long term through a variety of chance events. Thus, the long-term persistence of some taxa requires sustainable populations across entire landscapes or regions as predicted. Many species exploit chronological dissimilarity by moving between dissimilar habitats, requiring targets to distinguish key habitat combinations where these can be identified. The focal species approach attempts to amalgamate patterns and processes by identifying those species in a landscape that are most demanding of resources and then targeting them for organization. The kinds of resources needed by crucial species may be, for example, big areas, connectivity flanked by environment patches and multifaceted assorted habitats. However the other confronts that the park need to look at is the protection of river Ausable. The area around the river is currently being occupied slowly making the shows to deteriorating since the occupants are using the land for housing. This river is the

Discuss Nathanael Greene's Southern campaign. Why do some historians Essay

Discuss Nathanael Greene's Southern campaign. Why do some historians view Greene as being second only to Washington in importance in winning the war - Essay Example Greene was handed the responsibility of leading the then weak Revolutionary southern army that had already been led by three commanders who failed in their duties (Golway, 2005). He was given the duty of commanding the war against the British occupation of the south. With a small and poorly trained army, he was up against a more established and experienced British army. With the awareness that his troops were not able to win large and decisive wars, he planned brief and sudden attacks against the prominent British army. He took a bold step to divide his army into smaller groups, forcing the British troops to do the same (Tucker, 2009). He then ordered the Continental army to retreat, and the British, without realizing the tactic used against them, followed the Continental army. This drove the British army further away from their supply base, making them weaker and eventually losing the battle (Tucker, 2009). Some historians view Greene as second to Washington in the importance of winning the war because he was appointed by Washington and took orders from him (Carbone, 2008). He also succeeded where three other commanders had failed. In the same way like Washington, he was gifted with the ability to use small means to a significant advantage (Carbone,

Define consumer benefit, market segment and market size of a theatre Case Study

Define consumer benefit, market segment and market size of a theatre (for a real ) - Case Study Example Consumer Benefit Consumers of a particular product seek to identify products that would benefit them and satisfy their needs through knowledge of product attributes, which include brand image, brand perceptions, brand personalities, and brand characteristics (Whaling and Michigan State University, 2007). Consumers are constantly seeking products that would satisfy their unlimited needs with the maximum outcome benefit they can get from the product. The outcomes however vary from satisfaction of needs to getting solutions to particular problems and reduction if not elimination of frustrations. The attributes of a product are meaningless to a consumer if the outcome benefit they are seeking cannot be achieved from purchase of the product. The outcome benefit that the consumers are seeking to benefit from usually carries the rational and emotional component. The purchaser may at times not be the end user of the product but still goes ahead to seek a product that will help him or her ach ieve price and solution benefit. Hopgood have regular customers such as the local council and other companies who hire rooms for meetings and training of their staff. The company representatives responsible for hiring focus on the outcome benefit to their end users rather than just hiring a room. Market segmentation is basically based on the product benefit, and customer characteristics relation. Customers with specific needs and characteristics seek to benefit from specific products that match their situations (Evans, O'Malley, Maurice, and Patterson, 2004, pg 179). The functional benefits that consumers of Hopgood theatre achieve from their products are measured in terms of time and place with which the product is available, the duration that the services last and the prices with which the products are purchased. The shows being offered by Hopgood may be repeated in other theatres in other countries and the prices are normally the same although Hopgood may charge slightly higher i n venues located in the cities as compared to regional venues. Purchasers of goods achieve higher degree benefit with lower prices as compared to products with slightly higher prices although the venue of the shows levels up the price factor. Shows of its own kind are desired by many consumers of Hopgood considering the fact that the shows may not be repeated elsewhere. A variety of shows offered are highly appreciated by Hopgood product purchasers who have the opportunity of choosing from a list all current shows with prices charged for each show that is available on their website. Psychological benefit is also an important outcome that customers of Hopgood seek for when purchasing a product. This benefit enables the purchaser to achieve a pleasant feeling of acquired value for money and self worth. Customers seek to purchase goods that will enable them achieve the highest level of psychological satisfaction to build their own self-esteem and boost value for the products. The outco me is the benefit of the products they use and consume to satisfy their needs. Market Segment Market segment focuses on particular customer characteristics that differentiate one group of customers from another group. Customer profile is the determining factor that differentiates market segments of Hopgood theatr

Galileo Galilei Essay Example for Free

Galileo Galilei Essay Galileo Galilei is an Italian astronomer, physicist, philosopher, and mathematician. He ranks with Archimedes, Newton, and Einstein as one of the greatest scientists of all time. His discoveries, made with the crudest of equipment, were brilliant examples of scientific deduction. Galileo’s studies of natural laws laid the groundwork for the experimental scientists who followed him. Galileo was born at Pisa, the son of a musician who planned a medical career for him. He began studying medicine at the University of Pisa. According to legend, Galileo made his first major discovery at this time. He is said to have used his pulse to time the swinging of a suspended lamp in a cathedral; he found that, no matter how far the lamp swung, the timing has always the same (Drake, 2002). In later life Galileo established the fact that a free-swinging object, or pendulum, moves in uniform time intervals. Pendulum clocks are a common application of this principle. Thesis Statement: This paper scrutinizes the life and contributions of Galileo Galilei. II. Discussion Galileo constructed the first telescope used for astronomical observations; the observations he made supported Copernicus’ theory that the sun is the center of the solar system. In physics, Galileo discovered the principles of motion followed by swinging pendulums, falling bodies, and flying projectiles. Galileo used his heartbeat to time the period of a pendulum. He realized that a pendulum could be used as a standard of time for a clock (Rose 2004). Pendulum clocks are still sold today, more than three hundred years after their invention. Moreover, changing from the study of medicine to that mathematics and natural science, Galileo conducted experiments on gravity that brought him to public attention. In 1589, he became a lecturer on mathematics at the University of Pisa, and began his studies of falling bodies. According to legend, as mentioned earlier, he dropped objects from the Leaning Tower of Pisa to prove his theory that bodies fall at the same speed and with the same acceleration regardless of their weight and size. He also demonstrated that projectiles follow a parabolic path. These discoveries were contrary to the teachings of the ancient Greek scientist and philosopher Aristotle, many of whose ideas had for centuries been accepted without question. Galileo aroused such opposition that in 1951 he was forced to resign from the university (Rose 2004). The next year Galileo obtained a professorship in mathematics at the University of Padua, where he remained for 18 years. This was a period of successful research, acclaim, and prosperity for Galileo. In 1609, Galileo received news of the invention, in Flanders, of a device that made a distant objects appear larger. He immediately set out to build such a device for himself. The final result was a 32-power refracting telescope, with which he made series of major discoveries (Poupard 2005). He found by observation that the moon shone only from reflected light; that the Milky Way was formed of a multitude of stars; and that the planet Jupiter was circled by several moons. His discoveries caused great excitement among astronomers; he was besieged with orders for telescopes. In 1610, Galileo left Padua for Florence to become official mathematician and philosopher to Grand Duke Cosimo II de’ Medici. By the end of the year his telescopic discoveries included the rings of Saturn, the phases of Venus, and sun spots. His observations clearly confirmed the theory of the Polish astronomer Copernicus that the earth and planets revolved around the sun. The church, however, had accepted as conforming the Bible the earlier idea of the planets and sun revolving around the stationary earth. When Galileo visited Rome in 1611 he was given a welcome by Church officials befitting one of the greatest astronomers of all time, as he was then acknowledged to be. This gave him the courage to announce his support of the Copernican theory of the solar system. Controversy flared. Although warned by the Church to avoid religious interpretation of his theory, Galileo attempted to prove it by quoting the Bible. He was told by the Church in 1616 to abandon the Copernican theory because it contradicted the Bible. In 1632, however, he published Dialogue on the Two Chief Systems of the World, in which he revived his argument in favor of the Copernican system. Galileo was then summoned to appear before the Inquisition and forced to renounce the view that the earth moves around the sun (Poupard, 2005). Although sentenced to imprisonment, he was permitted to retire to his home, where he continued his studies. III. Conclusion As a conclusion, Galileo Galilei made great contributions to our society through his invention and discoveries. His works are highly acclaimed and made significant impact in the fields of mathematics, physics, astronomy, and in sciences. Reference: Drake, Stillman (2003).

Qualitative Tests Used For Carbohydrates Biology Essay

Qualitative Tests Used For Carbohydrates Biology Essay Carbohydrates are an essential component of our diet and an important source of energy for us. Most of the things generally included in our diet have a large ratio of carbohydrates present. Also the patients suffering from Diabetes excrete huge amounts of sugar in their urine which needs to be estimated. The purity of carbohydrates can also be checked by methods which can qualitatively estimate particular sugars. Hence the need for carbohydrate estimation arose. We have been estimating carbohydrates qualitatively since school time but it was just confined to observing a colour change or a coloured precipitate to detect the presence of a carbohydrate. None of us ever thought that these qualitative tests are highly sensitive and provide much more information than just detecting the presence of a sugar. In this study conducted, two qualitative tests used for carbohydrates were studied: Benedicts test and Seliwanoffs test. Benedicts test is a test used for detecting the presence of Reducing Sugars. The test was performed using Glucose which is the most common reducing sugar. Sucrose was used as a negative control. Different concentrations of glucose were tried ranging from 1.6 M to 1.6 mM and from 4% to 0.25%.Also along with concentration the amount of sugar was varied to find the sensitivity limits and the limitations of the test. The result of Benedicts test is usually a brick red precipitate but with some modifications different colours of solutions and different amounts of precipitate could be observed with slight variation in the concentration and amount of sugar. This suggests that this test being Qualitative is not only an indicator of the presence or absence of a reducing sugar but can also be used to roughly estimate the concentration of sugar present. It can be very useful in estimation of the concentration of sugar present in the urine of diabetic patients. Seliwanoffs test is a qualitative test used for distinguishing between Aldoses and ketoses. Ketoses form a cherry red condensation product whereas Aldoses react to form a blue-green condensation product, which may further change to a peach product. The test was performed using fructose as the sample sugar. Various concentrations of Fructose were used ranging from 4% to 0.01% to find the sensitivity limits and the limitations of the test. The test appeared to be sensitive even at 0.01% showing a very faint red colour. There was a huge variation in the intensity of colour obtained at different concentrations of sugar. But the drawback of the test was that the red colour of the solution was not stable. It intensified with increase in the duration of time. 2. INTRODUCTION Carbohydrates are the most abundant bio molecules on Earth. Each year, photosynthesis converts more than 100 billion metric tons of CO2 and H2O into cellulose and other plant products. Certain carbohydrates (sugar and starch) are a dietary staple in most parts of the world, and the oxidation of carbohydrates is the central energy-yielding pathway in most non-photosynthetic cells. Insoluble carbohydrate polymers serve as structural and protective elements in the cell walls of bacteria and plants and in the connective tissues of animals. Other carbohydrate polymers lubricate skeletal joints and participate in recognition and adhesion between cells. More complex carbohydrate polymers covalently attached to proteins or lipids act as signals that determine the intracellular location or metabolic fate of these hybrid molecules, called glycoconjugates. .Carbohydrates are polyhydroxy aldehydes or ketones, or substances that yield such compounds on hydrolysis. Many, but not all, carbohydrates have the empirical formula (CH2O)n; some also contain nitrogen, phosphorus, or sulphur. There are three major size classes of carbohydrates: monosaccharides, oligosaccharides, and polysaccharides Classification Carbohydrates can be classified on the basis of the various characteristics they possess. They can be classified on the basis of the number of carbon atoms in the sugar chain, the terminal functional group in the chain, the number of sugar subunits and the reducing activity of the sugar units. Depending on various basis they are of several types: A. According to the number of carbon atoms in the sugar chain: 1. Trioses: contain 3 carbon atoms (e.g. glyceraldehyde). 2. Pentoses: contain 5 carbon atoms (e.g. ribose). 3. Hexoses: contain 6 carbon atoms (e.g. glucose). B. According to the terminal functional group in the sugar chain: 1. Aldoses: contain terminal aldehyde group (-CHO) (e.g. glucose). 2. Ketoses: contain terminal ketone group (C=O) (e.g. fructose). C. According to the number of sugar subunits: 1. Monosaccharides: Monosaccharides, or simple sugars, consist of a single polyhydroxy aldehyde or ketone unit. The most abundant monosaccharide in nature is the six-carbon sugar D-glucose, sometimes referred to as dextrose. 2. Oligosaccharides: Consist of short chains of monosaccharide units(2-10) joined by characteristic linkages called glycosidic bonds. The most abundant are disaccharides, with two monosaccharide units. e.g. sucrose (cane sugar), which consists of the six-carbon sugars- D-glucose and D fructose. 3. Polysaccharides: The polysaccharides are sugar polymers containing more than 20 or so monosaccharide units, and some have hundreds or thousands of units. Some polysaccharides, such as cellulose, are linear chains; others such as glycogen, are branched. Both glycogen and cellulose consist of recurring units of D-glucose, but they differ in the type of glycosidic linkage and have different properties and biological roles. . D. According to the reducing activity of the sugar unit: Carbohydrates that can undergo oxidation are called reducing sugars. This depends on the presence of an exposed carbonyl group. 1. Reducing sugars: Certain sugars with a free carbonyl carbon can be oxidized by oxidizing agents such as ferric (Fe3) or cupric (Cu2) ion. The carbonyl carbon (anomeric carbon) is oxidized to a carboxyl group. Such sugars capable of reducing ferric or cupric ion are called Reducing sugars. e.g. lactose, maltose. 2. Non-reducing sugars: Sugars like sucrose contain no free anomeric carbon atom since the anomeric carbons of both monosaccharide units are involved in the formation of glycosidic bond. Therefore it is a Non-Reducing sugar. 2.1 Biochemical Tests for Carbohydrates The biochemical tests for carbohydrates can be divided into two categories: Qualitative Tests- These tests are performed to detect the presence of carbohydrates in a test sample. They are also used to detect the type of carbohydrate present. There are different types of qualitative tests for different types of carbohydrates. e.g. Fehlings and Benedicts test for reducing sugars, Seliwanoffs test for ketoses, Iodines test for starch,Bials test for detecting pentoses etc. They are not very sensitive as compared to quantitative tests and cannot estimate the exact amount of carbohydrates present but show some difference in the observation with variation in the amount of carbohydrate hence, can be used to make a rough estimate of the amount of sugar present. Quantitative Tests- These tests are the advanced form of qualitative tests and can be used to estimate the amount of carbohydrate present in a given sample. These tests use particular chemicals which form coloured complexes with sugars which can then be read at certain wavelengths using a spectrophotometer. Their absorbance can then be used to estimate the exact amount of carbohydrate present in the sample. e.g. Anthrone test, DNS Method, Phenol- Sulphuric Acid Method etc. 2.11 Qualitative Test Flow Chart for classifying an unknown carbohydrate A. Molisch Test Molisch test is used to distinguish between carbohydrates and non- carbohydrates. It is the preliminary test used to detect the presence of carbohydrates in a sample. Principle It uses concentrated sulphuric acid as a Dehydrating acid which dehydrates all carbohydrates to form Furfural or 5-hydroxymethylurfural from reaction of sulphuric acid with pentoses and/or hexoses. These products condense with ÃŽ ±-naphthol to yield a purple condensation product. B. Iodine and Potassium Iodide Test This is a test used particularly to detect starch and glycogen. Starch gives a blue-black colur with potassium iodide whereas glycogen gives reddish-brown colour. Principle Starch contains ÃŽ ±-amylose, a helical saccharide polymer, and amylopectin. Iodine forms a large complex polysaccharide with the ÃŽ ±-amylose helix, producing a blue-black colour. Simple Oligosaccharides and Monosaccharides do not form this complex with Iodine. Thus, the I2/KI test can be used to distinguish starches from other carbohydrates. C. Bials Test Bials test is used to distinguish between pentoses and hexoses. Principle This test uses concentrated hydrochloric acid as the dehydrating acid and orcinol with a trace of iron(III) chloride as the condensation reagent.. Pentoses subjected to the test yield a blue or green condensation product, while hexoses yield a muddy brown to grey condensation product. Pentose Dehydration Product Blue or Green condensation product (Furfural) Hexose Dehydration Product Muddy brown-Grey condensation product (5-hydroxymethylfurfural) D. Seliwanoffs Test Seliwanoffs test is used to distinguish between aldoses and ketoses. Principle This test uses 3N hydrochloric acid as the dehydrating agent as resorcinol as the condensation reagent. When mixed with Seliwanoffs Reagent, Ketopentoses react within 2 minutes to form a cherry red condensation product. Aldopentoses react after 2 minutes to form a blue-green condensation product, which may further change to a peach product. Fructose Hydroxy-methyl Cherry-Red Complex Furfural Identifying Reducing Sugars All mono and disaccharides with a free aldehyde or keto group act as reducing agents in alkaline solutions. The reducing properties of sugars are dependent upon the presence of actual or potential aldehyde or ketone groups. The enolization of sugars under alkaline conditions is an important consideration in reduction tests. The ability of a sugar to reduce alkaline test reagents depends on the availability of an aldehyde or keto group for reduction reactions. A number of sugars, especially disaccharides or polysaccharides have glycosidic linkages which involve bonding between each group, and hence there is no reducing group on the sugar; such as the case for sucrose, trehalose, inulin, glycogen, starch, and dextrin. In the case of reducing sugars, the presence of alkali causes extensive enolization especially at high pH and temperature. This leads to a higher susceptibility to oxidation reactions than at neutral or acidic pH. These sugars, therefore, become potential agents capable of reducing Cu+2 to Cu+, Ag+ to Ag and so forth. Reducing sugars can react with many different oxidizing agents. Fehlings test, Benedicts test and Barfoeds test have been used to distinguish between monosaccharides and disacc harides Monosaccharides fluctuate between a ring open form and a ring closed form. The ketone (-C=O) group, for Fructose and the aldehyde group (-CHO), for Glucose in the ring open forms can be reduced using these tests. Some sugar units in disaccharides also fluctuate between a ring open form and a ring closed form. These disaccharides are also reducing sugars because the ring open form has a ketone or aldehyde to react. Sucrose is one of the few disaccharides that do not have a ring open form so it is a non-reducing sugar.  ­Ã‚ ­Ã‚ ­ Ring Open Fructose and Ring Closed Fructose Ring Open Glucose and Ring Closed Glucose Reducing Sugars are oxidized by copper (II) ions. Benedicts reagent and Fehlings Reagent are mildly basic solutions whereas Barfoeds Reagent, a mildly acidic solution. The presence of red copper (I) oxide precipitate indicates that the saccharide has reduced the copper (I) ions. E. Fehlings test Principle Fehlings test uses a mixture of fehlings solution A and B. Fehlings solution A consists of copper(II) sulphate dissolved in dilute sulphuric acid. Fehlings solution B is sodium potassium tartarate dissolved in dilute NaOH. Both the solutions are mixed in equal proportions and used as fehlings reagent. This reagent is used as a general test for detecting reducing sugars. A reducing sugar reduce copper(II) ions to copper(I) oxide, forming a red precipitate. CuSO4Cu++ + SO4 2 Cu++  + Cu+ Glucose (Reducing Sugar) Cu+Cu2O (red precipitate) Cuprous Oxide F. Benedicts test Principle Benedicts test uses a mixture of copper(II) sulphate, sodium citrate, and sodium carbonate in a mildly basic solution. This reagent is used as a general test for detecting reducing sugars. A reducing sugar reduce copper(II) ions to copper(I) oxide, forming a red precipitate. CuSO4Cu++ + SO4- (Copper Sulphate) (Cupric Ion) (Sulphate Ion) 2 Cu++  + Cu+ Glucose (Reducing Sugar) Cu+Cu2O (red precipitate) Cuprous Oxide G. Barfoeds Test Benedicts test gives positive test results for all reducing sugars. However, not all reducing sugars react at the same rate. With different oxidizing agents, disaccharides are considerably less reactive compared to monosaccharides. A positive Barfoeds test result is similar to that observed with Benedicts solutions. Monosaccharides give positive Barfoeds test results within 2-3 minutes, while disaccharides do not react under the same conditions. Principle Barfoeds test uses copper(II) ions in a slightly acidic medium. If the reaction time is carefully monitored, this test can be used to distinguish reducing monosaccharides from reducing disaccharides. Reducing disaccharides cause the formation of copper(I) oxide after approximately 10 minutes.

Determination of Total Carbohydrate by Anthrone Method Principle Carbohydrates are first hydrolysed into simple sugars using dilute hydrochloric acid. In hot acidic medium glucose is dehydrated to hydroxymethyl furfural. This compound forms with anthrone a green coloured product with an absorption maximum at 630 nm. HCl anthrone Carbohydrate furfural/hydroxymethyfurfural Green product (630 nm) B. Phenol Sulphuric Acid Method for Total Carbohydrate Principle In hot acidic medium carbohydrates are dehydrated to furfural/hydroxymethyl furfural. This forms a green coloured product with phenol and has absorption maximum at 490 nm. H2SO4 phenol Carbohydrate furfural/hydroxymethylfurfural Green product (490 nm) C. Determination of Reducing Sugars by Nelson-Somogyi Method The Nelson-Somogyi method is one of the classical and widely used methods for the quantitative determination of reducing sugars. Principle The reducing sugars when heated with alkaline copper tartarate reduce the copper from the cupric to cuprous state and thus cuprous oxide is formed. When cuprous oxide is treated with Arsenomolybdic acid, the reduction of molybdic acid to molybdenum blue takes place. The blue colour developed is compared with a set of standards in a colorimeter at 620 nm. Cu2O+ Arsenomolybdate Molybdenum Blue (Cuprous Oxide) (500 nm) D. Estimation of Reducing Sugar by Dinitrosalicylic Acid Method This method is an alternative to Nelson-Somogyi method. It is a simple, sensitive and adoptable method during handling of a large number of samples at a time. However,  enzymatic  methods are usually preferred to DNS due to their specificity. Principle 3,5-Dinitrosalicylic acid   is an  aromatic compound  that reacts with reducing sugars to form  3-amino-5-nitrosalicylic acid, which absorbs  light  strongly at 540  nm. 3,5-Dinitrosalicylic acid 3-amino-5-nitrosalicylic acid E. Determination of Glucose by Glucose Oxidase Method Glucose is a widely distributed simple sugar with an active aldehyde group. Estimation of glucose by glucose oxidase gives the true glucose concentration eliminating the interference by other reducing sugars. Principle Glucose oxidase catalyses the oxidation of alpha-D-glucose to D-glucono-1, 5 lactone (gluconic acid) with the formation of hydrogen peroxide. The oxygen liberated from hydrogen peroxide by peroxidase reacts with the O-dianisidine and oxidises it to a red chromophore product. Glucose + O2 H2O2 + Gluconic Acid (glucose oxidase) H 2O2 + O-dianisidine Red-coloured product (peroxidase) (540 nm) 3.

METHODOLOGY 4.1 Benedicts Test Step 1- Pipette out 1 ml of glucose solution in some test tubes so that there is a triplicate for each set. Step 2- Pipette out 1ml of Distilled Water in one test tube which serves as blank and 1 ml of Sucrose solution (0.1M) in another which serves as a negative control. Step 3- Add 2 ml of Benedicts reagent in all the test tubes. Step 4-Transfer all five tubes to the boiling water bath provided and record the time for the appearance of precipitate. Step5- Make a subjective analysis of the colours observed. A scale of + to +++++ can be used to record the depth of the colour, from lightest to darkest. 4.11 Effect of variation in Carbohydrate Concentration (in M) The concentration of glucose was varied from 1.6 M to 1.6 mM keeping the reaction volume constant to 3 ml. The upper and the lower sensitivity limits and the optimum molar concentration of glucose was found for the test through subjective analysis. 4.12 Effect of Reaction Volume The reaction volume was reduced from 3 ml to 1.5 ml for all the concentrations of glucose ranging from 1.6 M to 1.6 mM to find any difference in the sensitivity range and the optimum molar concentration of glucose for the test. 4.13 Effect of variation in Carbohydrate Concentration (in %) The concentration of glucose was varied from 4% to 0.25%. Also the reaction volume was changed and the analysis was performed in two sets. The volume of reagent used was 5 ml whereas the volume of samples all concentrations in Set A and B were 50ÃŽ ¼l and 25ÃŽ ¼l respectively. 4.14 Effect of variation in Sample Volume The volume of glucose was varied for the same concentrations 4% to 0.25% to see the changes in the colour of solution obtained and at the same time find the upper and lower limits at which the test still remains sensitive. The analysis was performed in 6 sets with the following volumes of glucose: 200ÃŽ ¼l, 100ÃŽ ¼l, 50ÃŽ ¼l, 25ÃŽ ¼l, 12.5ÃŽ ¼l and 6.25ÃŽ ¼l. 4.15 Effect of Reaction Volume on the results obtained. Of the various sets tried 5 ml of Benedicts reagent and 200ÃŽ ¼l of sample gave the best results. To verify the consistency of results obtained the reaction volume was reduced. The analysis was performed in two sets. Set A with 2.5 ml of reagent and 100ÃŽ ¼l of sample and Set B with 1.25 ml of reagent and 50ÃŽ ¼l of sugar sample. 4.2 Seliwanoffs Test Step 1- Pipette out 1 ml of fructose solution in test tubes so that there is a triplicate for each set.

Step 4-Transfer all tubes to the boiling water bath for 2.5 mins. Step 5- Make a subjective analysis of the colours observed. A scale of + to +++++ can be used to record the depth of the colour, from lightest to darkest. 4.21 Effect of variation in carbohydrate concentration (in %) The concentration of fructose was varied from 4% to 0.015% keeping the reaction volume constant to 3 ml. The upper and the lower sensitivity limits and the optimum concentration of fructose were found for the test through subjective analysis. 5. OBSERVATIONS 5.1 Benedicts Test 5.11 Effect of variation in Carbohydrate Concentration (in M) A brick red precipitate was observed for all the concentrations of sample ranging from 1.6 M to 3.125 mM. But the last concentration of 1.6 mM showed a negligible amount of precipitate. Also once centrifuged the supernatant was found to be colourless for concentrations ranging from 1.6 M to 0.1 M. The supernatant was observed to be blue in concentrations ranging from 50 mm to 1.6 mM.

For concentrations 6.25 mM to 0.1 M there was an increase in the amount of precipitate observed with the highest amount formed in 0.1 M of sample. For the next two concentrations i.e. 0.2 M and 0.4 M the amount of precipitate formed was almost equal but again reduced for 0.8 M and 1.6 M glucose sample. Also after centrifugation the supernatant was found to be colourless for concentrations ranging from 1.6 M to 0.1 M. The supernatant was observed to be increasingly blue in concentrations ranging from 50 mm to 1.5625 mM.

RESULTS AND DISCUSSION 6.1 Benedicts Test 6.11 Effect of variation in Carbohydrate Concentration (in M) It can be observed that 0.1 M is the optimum concentration of sugar for Benedicts reaction with the reaction volume of 3 ml since the highest amount of precipitate is formed at 0.1 M. Also the supernatant obtained after centrifugation is colourless which suggests that the reaction is completed and there is no unused reagent left. Concentrations less than 0.1 M show decreasing amounts of precipitate and the colour of the supernatant is also increasingly blue. This suggests that as the concentration of sugar is lowered the amount of unreacted Benedicts reagent increases which leaves the solution blue even after the reaction completes. 1.6 mM sugar sample shows a negligible amount of precipitate formation which suggests that the reaction is not sensitive for concentrations lower than 1.6 mM. For concentrations higher than 0.1 M the amount of precipitate formed again decreases with increase in concentration which suggests that the concentration is too high as compared to the amount of reagent used and hence no more precipitate is formed after the reaction completes. 6.12 Effect of variation in Reaction Volume The reaction volume was reduced to half but has no effect on the results of the experiment. 0.1 M is the optimum concentration of sugar for the reaction with the reaction volume of 3 ml since the highest amount of precipitate is formed at 0.1 M. Also the supernatant obtained after centrifugation is colourless which suggests that the reaction is complete and there is no unused reagent left. Concentrations less than 0.1 M show decreasing amounts of precipitate and the colour of the supernatant is also increasingly blue. This suggests that as the concentration of sugar is lowered, the amount of unreacted reagent increases which leaves the solution blue even after the reaction completes. 3mM and 1.6 mM sugar samples show a negligible amount of precipitate formation which suggests that the reaction is not sensitive for concentrations lower than 3 mM with a reaction volume of 1.5 ml. For concentrations higher than 0.1 M, the amount of precipitate formed again decreases with increase in concentration which suggests that the concentration is too high as compared to the amount of reagent used and hence no more precipitate is formed after the reaction completes. 6.13 Effect of variation in carbohydrate concentrations (in %) The highest amount of precipitate was formed in 1% sugar sample but there was no consistency in the observations due to incorrect preparation of reagent. During the preparation of reagent instead of mixing Sodium citrate and Copper Sulphate together in hot water they were dissolved separately and then mixed. Also the solution was not made up to 500 ml with distilled water rather measured amount of water was added to the solution to make it 500 ml which made the solution dilute and hence gave incorrect results. 6.14 Effect of variation in Sample Volume Different volumes of sugar were tried for all the different concentrations. There was a variation in the colours obtained. 200ÃŽ ¼l of sugar reacted with 5 ml of reagent showed maximum variation in colours at different concentrations: Reddish Brown, Brown, Green, Greenish blue and dull blue obtained at 4%, 2%, 1%, 0.5% and 0.25% respectively. Sets with 12.5ÃŽ ¼l and 6.25ÃŽ ¼l of sugar volume did not show any noticeable changes in colour which suggest that the volume of sugar solution was not enough for the reaction to take place. 6.15 Effect of reduction in the reaction volume Reduction in the reaction volume made no difference to the variation in colours obtained at different concentrations of sugar which suggests that Benedicts reagent and glucose can be reacted in this ratio in any volume to estimate the concentration of glucose present in an unknown sample. 6.2 Seliwanoffs Test 6.21 Effect of variation in carbohydrate concentration (in %) A cherry red colour is observed for all the concentrations of Fructose used but the intensity of colour obtained decreases with decrease in concentration. The highest intensity is observed at 4% sugar concentration. 0.015% which is the lowest concentration of sugar used gives a very faint red colour which cannot be taken as pos

Child Observation Report Essay -- Adolescent Behavior

Confidential Material Detailed report of five observations. The names used in this Observation Report are fictitious. This is absolutely necessary to protect the privacy of the children being observed. Observation #1: Ron and aggression Date and time: Wednesday April 16, 2014; 11:25-12:50 Setting: Playground for 1st/2nd grade recess 11:25-11:50, 3rd/4th grade 11:55-12:20, Kindergarten recess 12:25-12:50 Activities observed: Children climbing across the climbing rings, watching children pretend play at the tire mountain and under the large wooden play structure with the blue plastic slide. My interaction with the children: I spent a lot of time answering questions about my name and where I am from for the children. Example A: There was one child named â€Å"Ron† on the first recess who was racing across the rings with another child, lost the race and fell to the ground. He then started to cry and called himself a loser. I pulled him aside to try to talk to him to find out what was wrong. He kept telling me that he was a loser because he didn’t win the race and he never wins, and that â€Å"all my friends think I am a loser because I cry all the time. They make fun of me because I cry. They beat me up. I am a loser.† I tried to reassure him and tell him I did not think he was a loser. I explained how I thought one of the reasons he lost the race was because he had been climbing across the rings for most of recess was tired from racing. He continued to cry even after his friends came over and tried to get him to play. He just sat in the sand sobbing, so I tried to tell him that his friends came over and asked him to play so it did not appear that they think he is a loser. He said they would beat him up. I tried to get him to go and see if they would play; initially, he refused to interact with his friends but then he got up and tried to find his friends. He searched for a few minutes and when he could not find them he started crying again and walked away from me. Date and time: Monday, April 21, 2014; 11:25-12:50 Setting: Playground for 1st/2nd grade recess 11:25-11:50, 3rd/4th grade 11:55-12:20, Kindergarten recess 12:25-12:50 Activities observed: Chi... ...g & Homer, Bruce.

Big Black Good Man

Big Black good Man and Battle Royal I believe Richard Wright's story â€Å"Big Black Good Man† was written in a time when racial prejudice was a major factor in society. In Today’s society we still have racial prejudice, but it is not as strong as back then. The point in which Richard Wright wanted to get by writing this story is that people should â€Å"never judge others by their race†. In the story, Olaf mentioned Jim was not the first black man he serviced, but he started to make drama of Jim’s behaviors in his head. I think Olaf was the type of person who is ignoring that he is a racist but he actually is one.This was the most important point that Richard Wright was trying to make. This story is focusing more on characters. There were two characters, which responded very differently to the black man. Olaf, whom was working in a hotel for guest services, has an average life, average job and also average thinking. Based on the story Olaf is a type of ma n that is happy with his life and lifestyle and respects others the way they are. Although, as soon as it comes to big black man who enters the hotel every thing about him suddenly changes, some unexpected fear surrounds him.However, every day of Jims stays in the hotel Olaf would gain more fears of a big black man. In his mind, Jim is a big, black, loud and violent man that wants to kill him. On the other hand, Lena responded very differently to the black man. Based on the story, Lena was poor and wiling to do anything such as prostituting to earn money, in order to take care of her four children. Even at the arguments she had with Olaf, she mentioned that he is just another man with manly needs â€Å"He’s just a man†¦I handle ‘im. † She was seeing his as an ordinary man who had good money and wants her; of course it was no fear of him to her conflicting than Olaf.She was called to Jim’s room every night and she was willing to continue. I believe she wouldn’t care if he is black or if he is big, all that matters was the reality of Jim as a man who has money to lead her for taking care of her children. They also ended up liking each other, and started dating and at the end of the story Jim was thankful to Olaf as well. Lena stopped prostituting and making love with Jim; she must have seen him as a good man so she was willing to drop her income. On the other hand, when the story ends Olaf realized Jim was not a violent and harsh man he actually is a big black good man.In addition, when it comes to comparing we can compare â€Å"Big Black good Man† by Richard and â€Å"Battle Royal† by Ralph Ellison. The point in which both narrators wanted to make was the fact of differences in race and struggling of being different. â€Å"Battle Royal† is about young African American who is ? struggling to have a place in their society. It was kind of hard for people back then to deal with this situation and it was al so hard for black people to get into white society. It was all about equality and identity, which they did not have, back then.However, this story was written in 1947, black society in the U. S. was struggling to find an identity for itself separate from the unfair force accrued by a white culture. Ellison uses the theme of blindness throughout the story as he describes the relations between the narrator and the characters in the story. The paper describes the story, beginning with a strange type of the death of the narrator's grandfather and the advice he gave him about life and how to behave as a black man. Grandfather’s advice leads the whole story making narrator to fallow his advice and using it trough his life.In the story, young black boy struggle to get ahead in a predominately white society, he wanted to reach this goal in using his grandfathers advice. His grandfather told him to â€Å"live with your head in the lion’s mouth. I want you to overcome ‘em with yeses, undermine ‘em with grins, agree ‘em to death and destruction, let ‘em swoller you till they vomit or bust wide open†. I believe his grandfather was trying to tell him to conform to the white people. The whole story shows his struggle and hardships his taking to reach his goal by fallowing grandpa’s advice.At the end of the story he also gives out a successful speech of this advice at his graduation. In conclusion, throughout time racism has been the cause of millions of deaths. In early centires racial prejudice was a major factor in society, now we see less racial prejudice. So many people still struggling because of racist people and some people are hiding their racisom. In both stories authors are trying to tell audiences stop judging people by their look, color and culture, there is absolutely no different between white and black it’s just a color. Human is a human and life goes on with all differences in people. Big Black Good Man â€Å"Big Black Good Man† Racism has existed for as long as humans have walked the earth. â€Å"Big Black Good Man,† by author Richard Wright takes place in 1957 in Copenhagen, Denmark at a cheap hotel on the docks. Olaf Jensen is a 60 year old white night porter who sees all kinds of people come there for a room. When Jim, a 6 1/2 foot tall black sailor who works for American Continental Line, arrives, the dilemma begins. Olaf is frozen by the sight of Jim and wonders whether he should give him a room. But we must read more deeply into the text to know what Olaf is actually feeling.Despite appearances, Olaf is not a racist because he has a multi-cultural background, he is afraid of Jim's size and power, not his skin color, and he feels insecure in Jim's presence. First, Olaf is not a racist because he has a multi-cultural background. In his youth Olaf was a in the services he was a sailor. While in the services over the world traveled all over the world. During his wor ld travels, Olaf has been exposed to a diversity of people from different background, races and cultures.While in navy, Olaf lived side by side with people of color â€Å"In his days, he’d worked and eaten and slept and fought with all kinds of men. † Olaf had been exposed to so much with so many culture. Olaf even lived in the melting pot on the world. â€Å"He lived in New York city for ten years. † For him to live so long in a city with such diversity suggests a open-mindedness to tolerance for different. During his travels, he even had learned 8 languages: â€Å"English, French, German, Danish, Dutch, Swedish, Norwegian and Spanish. He took the time to learn these languages so he could better understand the people he was associating with. This makes it hard to believe that he was a racist. 1950’s segregation was still going on at this time, but it didn’t make any difference to Olaf. He actually states â€Å"It was not the hotel did not admit men of color†¦. He took all comers, blacks, yellows, whites, and browns. † Olaf did not discriminate on the basis of skin color. â€Å"to Olaf men were men. † Second, Olaf is not a racist because he is afraid of Jim's size and power, not his skin color.Jim’s sheer size at â€Å" 61/2 feet into the air, almost touching the ceiling. † Would cause any men to be afraid. Olaf constantly emphasize Jim’s enormous physique and power, describe as â€Å"His chest bulged like barrel† and â€Å"his rocklike shoulders hinted mountain ridgesâ€Å" and â€Å"the stomach ballooned like a threatening stone. † Olaf description of Jim gives a great image of Jim as a massive size and intimating features. It is easy to understand Olaf fear of Jim. He afraid so Jim that â€Å"With just one look at Jim’s hands he would have shivers†. Olaf was completely terrified of Jim.Later in the story, Jim walked in to the office and demand Olaf to s tand. Standing inch apart Jim lifted his mammoth hand his around Olaf throat. † Olaf lost control of the reflex of his body and felt a hot stickiness flooding his underwear. Olaf fear made him loss control over his own bodily function. I only could imagine this situation and reacting any different then Olaf. Third, Olaf is not a racist because he feels insecure in Jim's presence. Olaf is a small 5†7† 60 years old Caucasian man. Although he wasn’t poor he wasn’t rich, either a lifetime of working, he was still only a night potter.In comparison, Jim who has money, youth and power. He envied Jim â€Å" the easy manner in which it moved with such a creeping powerful motion† He felt that Jim presence command attention and respect. Having this enormous men in his presence frightened and insulted Olaf. â€Å"He believed that this man had come here expressly to remind him how puny, how tiny, and how weak he was. † Olaf offers to take Jim‘s bag, but Jim replies â€Å"That‘s too heavy for you, big boy: I‘ll take it† Olaf feel that this man makes him inferior and less of a man. As a result, Olaf â€Å"Seethed against himself for his involuntary weakness†.He was angry for allowing this men to make him feel weak. Unable to stand up to Jim, he feels â€Å"Him self beaten†, stating â€Å"He thinks am nothing. † Olaf felt so belittle by this man specially after what happen with Jim in his office when due to true fear he wet him self he was so embarrassed that he couldn’t even tell his wife â€Å" he wept†¦. He went home and lied to his wife, he had an upset stomach. † Olaf was so embrace about what had happen he lied. Olaf was so insecure of him self after meeting Jim. This essay has made it clear that Olaf is not a racist but just a very afraid men.A men that aloud his fear cloud his judgments. Even thou he was afraid he never aloud him self to act upon his fears. T his story is a great example of how important close reading is. If you just focus on the vocabulary without putting any thought to what you read you could believe he is a racist. But once you look into the text and take into count the complete picture. An after only after you have read and reread is that the truth come to light. This story show us a great example of not judging a book by it cover. Even thou Jim was huge and scary he was one of the nice people.

On Being Sane in Insane Places Essay

Have you ever been in a confrontation with someone where they ended with calling you a lunatic, crazy, or insane? It does not feel too great. But at least you know you are sane, and to everyone else around you, you seem â€Å"normal.† Can you walk down the street and visibly see a difference between a sane and insane person? There are some people however that are permanently labelled as â€Å"abnormal† or â€Å"insane.† These people are diagnosed as â€Å"mentally ill† and are forever stigmatized and in some cases, dehumanized because of such labeling. Is it easy to distinguish the sane from the insane, or is it in fact the environment and contexts in which observers find these people? David L. Rosenhan formulated an experiment to investigate if psychiatrists could identify the difference between people who are mentally ill and those who are not. According to Rosenhan, â€Å"there are a great deal of conflicting data on the reliability, utility, and meani ng of such terms as â€Å"sanity,† â€Å"insanity†Ã¢â‚¬ ¦ normality and abnormality are not universal† (Rosenhan, 1973, pg.310). Rosenhan formed a group of 8 people who attempt to gain admission to 12 different hospitals across the United States. The psuedopatients each claimed of having textbook symptoms of schizophrenia. Once admitted, the psuedopatients each described their histories truthfully, and â€Å"they strongly biased the subsequent results favor of detecting sanity† (pg.313). Each psuedopatient â€Å"ceased simulating any symptoms of abnormality† (pg.313). Nursing reports obtained that each pseudopatient â€Å"exhibited no abnormal indications† (pg.313). The average length of hospitalization was 19 days, and upon discharge, each psuedopatient had a case summary written. All of the summaries were â€Å"unintentionally distorted by the staff to achieve consistency with a popular theory of the dynamics of schizophrenic reaction† (pg.316). Each psuedopatient upon discharge was reported as in remission, not cured, which perpetuates the negative label. These ascribed labels are permanent, and puts the diagnosed person at a disadvantage forever. People diagnosed as mentally ill are treated dif ferently, in most cases they are treated as if  their thoughts and opinions cannot be trusted or taken seriously. This is not fair, nor is it accurate. There is an â€Å"enormous overlap in the behaviors of the sane and the insane†(pg.318). The sane are not always sane, similarly, â€Å"the insane are not always insane†(pg.318). While reading this article, I was reminded about the homeless, and that many people assume that just because they are homeless, they are likely to have a mental illness. Now I see why many people assume this; the reason is the environment and contexts that civilians see these homeless people in. It is possible that some of these people are mentally ill, but it is more likely that they are in their position because of other reasons. From a sociological perspective, this experiment highlights the conflict perspective. In class, we have discussed how power is the core of all social relationships, all social systems feature a superordinate group and a subordinate group. In mental institutions, as well as in the public, conflict perspective is conveyed via sane people discriminating the allegedly insane people. Psychiatrists, nurses, and even civilians are above the mentally ill, because they are â€Å"sane† while the â€Å"insane† are incapable of having valid opinions. Pow er is scarce, and everyone wants some of it, and unfortunately this permanent label is debilitating for the person who is marked with it, leaving them with little hope of upward mobility in our society.

Good and bad. Mobile phone Essay

Handphones have become a major part of our lives. Today, it is being widely used all over the world. Most of us, that is. It has metamorphosized from being a luxury to necessity for some of us. Handphones are one of the things that we cannot do without, for one reason or another. We have come to depend on it, increasingly so, and in doing so it has become a need. Having handphones can prove to be very useful but it can also be said otherwise. There are both advantages and disadvantages to owning a handphone or being in the midst of people who own them. Owning a handphone means one can be easily reached when on the road or when one is not at home or in the office. It can even be used when one is overseas, using the ROAM service. There are features such as voice messages and SMS, in other words, Short Message Service. This is to allow people to contact a handphone owner even if he is busy or is unable take the call. These features enable the owner of the phone to know why he is being called, so on and so forth. SMS-es help to keep it short. Without calling, you can leave a short message. Nowadays though, people use it to have conversations, especially the young, and those who find it easier to message than to talk. It is also cheaper and thus allows one to save on talk time. Another advantage would be that of being able to call whenever and wherever there is an emergency, for example when you are in a road accident or you need to call someone and there does not seem to be any public phones nearby. There are also different mobile service plans to choose from to suit one’s communication needs, be it longer talk time, free incoming or outgoing calls, or more free local SMS. As such, one can reap much benefits and save costs. Nowadays, handphones rarely just have one function, which is to make and receive calls. There are more functions and features such as listening to music, taking pictures with an in-built camera, playing games, and even logging on the internet and etc. There are also disadvantages that come along with the usage of handphones. Firstly, there are limitations to where a handphone can be used. If there were no reception, then there would be no possibility of making or receiving calls. On another note, a person can say he is at a certain place when in fact he s somewhere else. So, you can never be too sure of where a person  might actually be. User-abuse is another factor. Here, what is meant by user-abuse is the fact that some users are not considerate in that they make use of the phone in places where it is not allowed. As such they disturb others. It is one thing to let it ring loudly, but yet another, to be answering the phone. For example, in movie theatres, plays and the like. It is said that there are dangers of handphone radiation, though there is no conclusive evidence to prove a link between cancer and handphone radiation. Lastly, handphones cannot be used in most parts of hospitals as it could affect the readings on the equipments due to the radiation emitted and would pose as great danger to the patients.
