Evaluation of a Website www.pbskids.org Essay Example | Topics and Well Written Essays - 750 words

Evaluation of a Website www.pbskids.org - Essay Example I am particularly attracted by the website www.pbskids.org. This website combines entertainment with education, and is very attractively designed. The main draw of the website is the great technical skill of its design, which facilitates its use by children. It is a great example of how learning can be made fun. By incorporating characters, such as Barney & Friends, Curious George, Sesame Street, and Thomas and Friends, into spelling, number and letter games, the website educates and entertains. The bright colors, and easily understandable links, are very child-friendly. With websites ranging from the institutional to the personal, it is essential to develop the skill of objectively evaluating a website. Obviously, a commercial website cannot serve as a source for academic purposes, and a website with links to a pharmaceutical firm cannot be cited for medical research. Several criteria, such as accuracy, authority, objectivity and currency, come into play in evaluating a website (Cor nell University Library, 1998). Evaluation of the website www.pbskids.org, based on the criteria of reliability of the source, the credentials of the author, and the information available, gives an accurate picture of the website. The reliability of the source is of paramount importance in evaluating a website. ... Virgin Islands, Guam and American Samoa. PBS reaches nearly 123 million television viewers and more than 21 million online visitors in a month. It is America’s largest public media enterprise. The organization’s mission statement clearly reflects its focus on education. It is a measure of the strength of its credentials that the website has a link to the home page of the PBS, where a detailed account of the organization, its mission statement, and terms of use are all clearly laid down. As the domain name is clearly preferred, the producer of the website is unequivocally stated, and the credentials of the organization are reliable, it may be accepted that www.pbskids.org is the product of a reliable source. The credentials of the author is the other strong criteria in the evaluation of a website. www.pbskids.org does not list any author. In this case, the absence of a single author is not relevant, as the domain name of the website indicates that the source is an organi zation. As the website is sponsored by an organization, and the credentials of this organization, PBS, are genuine, the authority of the website may be accepted. In the absence of an author, the credentials of the organization may be taken in its stead. PBS KIDS is the winner of several Daytime Emmy Awards and features on many reliable surveys, including Nielsen and Google Analytics. It is clear that PBS is a leading player in curriculum based media, and has the authority to deal with this content. The page gives a direct link to the home page of the organization, where detailed contact information, including e-mail id’s and telephone numbers, are provided. Again, it is evident that the organization is very transparent in stating the purpose and

The Importance of Water Essay Example for Free

The Importance of Water Essay Water is one of the most important molecules necessary to life. humans, for example, are made up of 70% water. Osmosis is a form of intracellular transport which is important in maintaining a correct balance of ions and substances between the blood and the inside of cells, for example. If the oncentration of an ion is too high outside a cell, water will br pulled out of the cell by osmosis in order to increase the water potential and thus retore balance. This is the case in ORT (oral rehydration therapy) which is used to treat diarrhea ocurring due to cholera for example. The ORT packs ontain salt and electrolytes which are transported into the epithelial cells after ingestion and thus lower the water potential of the cell by causing water to be pulled into the epithelial cells from the gut lumen, thus stopping diarrhoea. Diarrhoea is caused by an too high water potential in the lumen of the gut, often due to a movement of water by osmosis. In the case of lactose intolerance, when lactose is ingested it will not be broken down and continues along the gut, thus causing water to be pulled out of the cells and liquefying the stools (diarrhoea). Water is important in thermoregulation. When the thermoreceptors perceive an increase in temperature, a signal is sent to the heat loss centre in the hypothalamus which starts the heat loss mechanism such as vasodilatation, lowering of body hair, and sweating or pantinh. Sweating allows to lose heat by evaporation off the skin, or mucous membranes in the case of panting. If there is not enough water in the body, sweating cannot take place and thus normal core temperature cannot be restored to normal value, which may cause overheating. Water is also the main molecule present in the cohesion-tension theory. Water is pulled up from the soil by osmosis from the root hairs of a plant, due to a lower water potential inside the root hair cell. Higher up, the plant is transpiring through its stomata (the rate of transpiration increases as temperature or wind increases) which pulls water out. There is an unbroken column of water from the stomata down the xylem of the plant, all the way down to the root hairs of the plant, so when water is pulled out of the stomata it is also pulled up from the root hairs of the plant up the xylem. The reason for this is the cohesion of the water moleules caused by hydrogen bonding between the molecules. There is also tension between the inside walls of the xylem and the water column this is why the diameter of a tree is larger at night due to a smaller rate of transpiration thus less tension. Water is also responsible for maintaining the shape and turgidity of plant cells by making the cell membrane push against the cell wall. If there is not enough water in the cell, it will be plasmolysed and flaccid.

Mel Levines A Mind at a Time Essay example -- Cognitive Psychology Ch

Mel Levine's A Mind at a Time Mel Levine’s book, A Mind at a Time, describes many aspects of cognitive psychology and attempts to apply them to the educational system for young children. This book also makes suggestions for parents that have children with cognitive difficulties. The chapters in this book are designated to various aspects of cognitive psychology as they pertain to children. This paper focuses on chapter six in A Mind at a Time, which is titled â€Å"Making Arrangements: Our Spatial and Sequential Ordering Systems.† This is a very interesting chapter because it incorporates many aspects of cognitive psychology. In this chapter, Levine focuses on how children organize their world in terms of learning, thinking, and remembering. Levine states that children have two ways in which they organize the information they receive from the world around them. He refers to these methods as sequential ordering and spatial ordering. He defines spatial patterns as, â€Å"assembled parts that occupy space and settle on the doorsteps of our minds all at once† (Levine, p.151). Many examples are given of when spatial ordering is prevalent, for instance, when a student draws a map or recognizes the features of a person’s face. Levine defines sequential patterns as information gaining â€Å"admission to the minds one bit at a time and in an order that’s meant not to be missed† (Levine, p.151). He says that sequential ordering is used when students try to master a science project or learn a telephone number. Neurologically, Levine states that sequential ordering is carried out on the left side of the brain and spatial ordering is carried out on the right side of the brain. He also makes referen ces to the possibility of childr... ...e abnormalities in their ability to learn efficiently. Throughout the book he is very supportive. He offers parents many great strategies for dealing with the problems of their children. The book A Mind at a Time gives parents a way to learn about their child’s mind without a lot of technical terms. The main problem I see with this book is that it may lead parents to discover potential problems with their children at much too young an age. Levine’s most important error is that he does not mention the age at which the minds of children develop. I feel that this book could be helpful to many parents and harmful to others. Parents, as well as other readers, need to be cautious when reading this book. Works Cited: Levine, M. (2002), A Mind at a Time. New York: Simon & Schuster. Matlin, M.W. (2002). Cognition. (5th ed.).

Cheaper by the Dozen :: Free Essay Writer

Cheaper by the Dozen â€Å" Cheaper by the Dozen†, based on a real-life story of the Gilbreth family, is a fantastic book. This hilarious comedy about a family with a dozen children kept me in stitches until the end! This family, run like a well oiled machine, took me on Sunday rides through the country, battles in the family court, summers at the sea, Father’s theories on motion study, and the economic removal of the whole families tonsils. I loved it! I find it truly amazing. Not only did the family boast twelve children, but they all learned to speak foreign languages, touch typing, mental arithmetic, and even Morse Code- all because their father worked out dozens of ingenious ways to motivate them- although often it was quite reluctantly on their part. I had many laugh out loud moments, and at times would have enjoyed being a part of this large and loving family, or perhaps raising one of my own in the same manner†¦imagine that! It probably could never happen. I can’t imagine living with twelve brothers and sisters and getting along! Actually, I would not call it getting along; I would call it survival, by jimgo! The Gilbreth family of twelve red-haired, freckle-faced children parented by efficiency experts and pioneers in the field of motion study, Lillian and Frank, were a bit eccentric and extremely funny. I can still remember one of the lines a child blurted out at the dinner table â€Å"Please, we are NOT in the mood for an organ recital.† This was the standard reprimand for belching in the family and never intended for public airing. I also enjoyed the part when one of the children said to a dinner guest, â€Å"Is this of general interest?† Although these twelve children were highly disciplined by their father, (mother, for the most part, would just agree with father) in a couple instances they were able to catch father off guard, like when the children would continually ask him â€Å"Father can you touch type?† â€Å"No,† he would reply, â€Å"but I can teach it!† Nothing was considered more of a sin than wasting valuable time, that is why the father, Frank timed himself trying to go as fast as he possible can with almost everything. Every movement of everyday must be functional. He timed himself buttoning his shirt to see which way was faster, top-bottom, or bottom-top. He timed himself shaving to see which way took longer, using to brushes to apply the shaving cream, or one.

Cross cultural relations with film analysis

The movie â€Å"Boyz in the Hood† deals with issues of racism and cultural stereotyping. It also deals with issues of personal identification and ambition and the issue of equality in opportunity, regarding schools, money, jobs, and personal safety. The characters in â€Å"Boyz in the Hood† represent a diverse group of young African Americans who must find their way through a world of violence, poverty, gangs, drugs, and broken families.Throughout the movie, the audience is reminded that many of the problems facing the movie's main characters are not of their choosing or making but are issues and problems which they have been made to deal with simply because of the circumstances of their birth, their skin color, and their socio-economic standing in society. Early on in the film, the audience is able to see Tre, Ricky, and Darin (Doughboy) as fairly typical kids who want to play football and enjoy being with one another.But Tre has already seen his house broken into, the three friends have passed by crime scenes and an impoverished neighborhood, There doesn't seem to be anywhere they can go to just be regular boys. Instead, they are made to be a part of crime and suffering from a very early age. The part of the movie that isn't actually shown, but the audience can imagine as a contrats is neighborhoods were kids can play and have parks and baseball games and not worry about gunfire or police or gangs or drugs.This vision which is not in the film, of a normal life, is the opposite of what the characters in the film have to deal with and the only difference is their racial origin, being African American. The characters in the movie as they get older seem to want to be a part of this â€Å"other† world, the world of whites and even though they remain true to their own cultural identities and participate in the â€Å"hood† culture, each of the characters seems to either want or is actively looking for a way out of the â€Å"hood. â€Å" Doughboy is sent to prison and looks to be the one who is most likely to become a thug. Still, due to the early scene in the movie where he is beaten up by an older kid who takes Ricky's football, the audience knows that Doughboy had to get tough in order to survive in the hood. It is almost as though his own acceptance of being a thug in the hood helps protect his brother, Ricky, and Trey from the violence around them in the hood. Later in the story, Doughboy's â€Å"fatherly† personality will start the chain of conflict that results in his brothers' death and eventually his own.But until that crises happens, Doughboy is like the father of the other two friends and the audience understands that despite his rough exterior he is really a compassionate person who sees a lot of potential in his brother and wants good things to happen for his friends and family. Because the characters in Boyz in the Hood, the main ones, are good people, the tragedies that happen to them are viewe d as not being of their making. Tre is stopped by an African American police officer who shoves his gun in his face and threatens to kill him simply because he, the police officer, does not like African Americans.Even though this is a short scene, it is a very important scene. It shows how an African American (the police officer) can be so alienated from their own race, and so hateful toward them that they actually become a part of the oppressive system which causes African Americans to suffer in poverty and be thought of as criminals and dangers to society. In the long run, Tre cannot bring himself to become an avenger for Ricky's murder. This is a demonstration that not all African Americans are alike, they are not prone to violence or revenge or gangs or shooting their enemies.Tre decides his life is more important than revenge. When he does so, he is both embracing his culture and refusing the more negative aspects of it. He is an African American who wants to improve his life a nd his family and his neighborhood and not become a thug like Doughboy even if he understands the reasons for Doughboy's actions. In each case, with the main characters of â€Å"Boyz in the Hood† their actions and options seem to be somehow influenced by the â€Å"white world† that they never really see.they aspire to become a part of that society and make good of their lives. They long for another life, but their life is filled with gunfire, helicopters, thugs, prostitutes, drugs, and violence. The reason they have been placed in such terrible circumstances are based in racism. The backdrop to the story is that white money-makers want to bring the property values in the Hood down as low as possible so they can but cheap real-estate; whites sell guns and liquor and drugs to the people in the Hood, but they would never set foot in the place themselves.There is no real sense of justice in â€Å"Boyz in the Hood† the only thing which comes close is when Doughboy do es kill the gang-bangers who killed Ricky. But even this is sad because it is not true justice but vigilantism and everyone knows Doughboy will be killed himself, eventually. The message is: no-one in official capacity care bout what happens to the people in the hood. In order to survive, they must often â€Å"lower† themselves, despite their best efforts, to the level of stereotype which has been used against them in a racially motivated way in the first place.

Children who are enrolled in schools that reflect their culture and values of the their communities tend to do better. Unfortunately regardless of these findings the majority of African American students continue to attend schools that do not reinforce their family and community culture, values and aspirations, and beliefs. Though families and communities continue to educate their children, these children do at some point enter formal education venues. It is here in this formal education that the aspirations, history, expectations, values, and culture of American society is reflected.

A Deeper Darkness - Edgar Allen Poe essays

A Deeper Darkness - Edgar Allen Poe essays Edgar Allan Poe is considered to be one of the most influential short story authors of mystery, suspense, and the supernatural. His usage of literary techniques compels his reader to finish his tales at one sitting. It is believed that Poes usage of first-person narrative in his short stories enhances an underlying emphasis on the mysteries of the self, of others, of nature, ad of the universe through the narrators observations. Much of Poes works were used to undercut the easy optimism and certainty characteristic popular to his time because of his usage of the darker aspect of life and living. His works carry within them multiple senses of depths. Not merely representing the physical, his tales also have metaphorical depths of mystery, of uncertainty, of the Unknown. In most of Poes writings his sense of style and influential views are present through the uniqueness of his works. Regarded as the architect of the modern horror tales, Poe was also the principle forerunner of the art for arts sake movement in nineteenth-century European literature (Poe Intro., 2749). He is also credited with parenting two other popular genres: science fiction and the detective story (Keller, 1898). He demonstrates a brilliant command of language and technique as well as an inspired and original imagination (Poe Intro., 2749). Throughout his writing career Poe included personal experiences in his writing from his war with alcoholism to the death of young wife. The traumas and bizarreness of his life also give his writings an extra flare of suspense and the element to spark emotion in the reader. However, such traumas as losing his family to tuberculosis seemed to enthrall him into the arms of death. Thus, when observing details in his poetry and stories, the essen ce of tuberculosis symptoms are revealed. His pessimist outlook of life lies within the symbols of darkness an...

Biography of Rafael Carrera - Rafael Carrera Profile

Biography of Rafael Carrera - Rafael Carrera Profile Guatemalas Catholic Strongman: Josà © Rafael Carrera y Turcios (1815-1865) was the first President of Guatemala, serving during the turbulent years of 1838 to 1865. Carrera was an illiterate pig farmer and bandit who rose to the presidency, where he proved himself a Catholic zealot and iron-fisted tyrant. He frequently meddled in the politics of neighboring countries, bringing war and misery to most of Central America. He also stabilized the nation and is today considered the founder of the Republic of Guatemala. The Union Falls Apart: Central America achieved its independence from Spain on September 15, 1821 without a fight: Spanish forces were more desperately needed elsewhere. Central America briefly joined with Mexico under Agustà ­n Iturbide, but when Iturbide fell in 1823 they abandoned Mexico. Leaders (mostly in Guatemala) then attempted to create and rule a republic they named the United Provinces of Central America (UPCA). Infighting between liberals (who wanted the Catholic Church out of politics) and conservatives (who wanted it to play a role) got the best of the young republic, and by 1837 it was falling apart. Death of the Republic: The UPCA (also known as the Federal Republic of Central America) was ruled from 1830 by Honduran Francisco Morazn, a liberal. His administration outlawed religious orders and ended state connections with the church: this enraged the conservatives, many of whom were wealthy landowners. The republic was mostly ruled by wealthy creoles: most Central Americans were poor Indians who did not care much for politics. In 1838, however, mixed-blooded Rafael Carrera appeared on the scene, leading a small army of poorly armed Indians in a march on Guatemala City to remove Morazn. Rafael Carrera: Carrera’s exact date of birth is unknown, but he was in his early to mid-twenties in 1837 when he first appeared on the scene. An illiterate pig farmer and fervent Catholic, he despised the liberal Morazn government. He took up arms and persuaded his neighbors to join him: he would later tell a visiting writer that he had started out with thirteen men who had to use cigars to fire their muskets. In retaliation, government forces burned down his house and (allegedly) raped and killed his wife. Carrera kept fighting, drawing more and more to his side. The Guatemalan Indians supported him, seeing him as a savior. Uncontrollable: By 1837 the situation had spiraled out of control. Morazn was fighting two fronts: against Carrera in Guatemala and against a union of conservative governments in Nicaragua, Honduras and Costa Rica elsewhere in Central America. For a while he was able to hold them off, but when his two opponents joined forces he was doomed. By 1838 the Republic had crumbled and by 1840 the last of the forces loyal to Morazn were defeated. The republic sundered, the nations of Central America went down their own paths. Carrera set himself up as president of Guatemala with the support of the Creole landowners. Conservative Presidency: Carrera was a fervent Catholic and ruled accordingly, much like Ecuador’s Gabriel Garcà ­a Moreno. He repealed all of Morazn’s anti-clerical legislation, invited the religious orders back, put priests in charge of education and even signed a concordat with the Vatican in 1852, making Guatemala the first breakaway republic in Spanish America to have official diplomatic ties to Rome. The wealthy Creole landowners supported him because he protected their properties, was friendly to the church and controlled the Indian masses. International Policies: Guatemala was the most populous of the Central American Republics, and therefore the strongest and wealthiest. Carrera often meddled in the internal politics of his neighbors, especially when they tried to elect liberal leaders. In Honduras, he installed and supported the conservative regimes of General Francisco Ferrara(1839-1847) and Santos Guardiolo (1856-1862), and in El Salvador he was a huge supporter of Francisco Malespà ­n (1840-1846). In 1863 he invaded El Salvador, which had dared to elect liberal General Gerardo Barrios. Legacy: Rafael Carrera was the greatest of the republican era caudillos, or strongmen. He was rewarded for his staunch conservatism: the Pope awarded him the Order of St. Gregory in 1854, and in 1866 (a year after his death) his face was put on coins with the title: â€Å"Founder of the Republic of Guatemala.† Carrera had a mixed record as President. His greatest achievement was stabilizing the country for decades at a time when chaos and mayhem were the norm in the nations surrounding his. Education improved under the religious orders, roads were built, the national debt was reduced and corruption was (surprisingly) kept to a minimum. Still, like most republican-era dictators, he was a tyrant and despot, who ruled mainly by decree. Freedoms were unknown. Although it is true that Guatemala was stable under his rule, it is also true that he postponed the inevitable growing pains of a young nation and did not allow Guatemala to learn to rule itself.

Write an theoretical analysis on your Diagnostic essay using your

Write an theoretical analysis on your Diagnostic using your summary on Ways of Reading - Essay Example One of the important lessons that I acquired in the process of reading is that it is generally an active process (Bartholomae and Anthony 24). Reading usually entails the search of information by way of communication with the author. The book provides valuable tips and strategies that can help students struggling with English on ways of improving their reading and writing skills. As an active process good reading practices demands that students attempt to get deeper into the thinking of the author by responding to some of the claims made in the book or providing their feelings on the same. Such a way of reading is important in the sense that it helps the student to understand the deeper meanings of the text. The method also helps the students acquire new vocabularies and ideas in ways that are easy to recall. Another important benefit of applying the strategy of active reading is that the student manages to improve his writing skills by observing the new ways and creative manner in which the author develops his writing skills. After reading different books, I have learnt to identify the beauty of words by observing the creative ways in which they have been used. I now know that both reading and writing are arts that can be acquired, developed or lost depending on the way in which students engage in them. Before I read Ways of Reading, I had many problems with grammar and sentence structures. I used to write very long sentences that had a lot of grammatical and punctuation mistakes. After reading the book, I have learnt to observe the rules of sentences and punctuation in different texts, which have helped me to sharpen my own skills in the process. Another important point that is made in the book is that good writers are always good readers. It is not easy for a person to develop good writing skills if he or she does not enjoy reading. The way of reading must be involving on the part of the

Financial Econometrics Coursework Essay Example | Topics and Well Written Essays - 2000 words

Financial Econometrics Coursework - Essay Example In 2003, the U.S. Securities and Exchange Commission (SEC) mentioned that the R-square of the regression analysis was insufficient to determine the effectiveness of hedging. In a speech by a professional accounting fellow from the office of the chief accountant of the U.S. Securities and Exchange Commission, stated that determination of hedge effectiveness should consider the slope of the coefficient of the regression analysis. This coefficient reflects the minimum variance hedge ratio.1 The interpretation of the regression slope coefficient is the average change in the dependent variable: real total expenditure on food for a unit increase in the independent variable: Real total expenditure on goods and services. The slope coefficient it 0.32, thus for every 1 unit change in real total expenditure on goods and services, there is a 0.32 unit change in real expenditure on food. Omission of an important independent variable such as real price of food relative to other goods will result in the decreased ability of the model to predict the real total expenditures on food given the real total expenditures on food. The independent variables used to predict 99.9% of the dependent variable: real consumption expenditure as indicated by the value of the adjusted-R Squared. The Durbin-Watson value of 1.85 indicates there is no signs of first-order serial correlation in the residuals of a time series regression. The values of Akaike info criterion (AIC) -268.2093 and Schwarz criterion -273.6530 are extremely low indicating the need for modification in the regression model by changing the independent variables. The t-statistic value could be compared with the critical t-value which is not available. The reported Probability is the p-value, or marginal significance level. Since this probability value of the regression analysis (F-statistic) is less than the size of the test, say 0.05, the null hypothesis could be rejected. This indicates that the

Gender and Consumer Culture Essay Example | Topics and Well Written Essays - 3000 words

Gender and Consumer Culture - Essay Example The culture of consumption is related with goods and products, where the purchase activities are largely grounded on the quality of the products and the value of its material usage. The difference in style possessed by different genders has therefore often been evaluated during the transitional phase, from pre-industrial economy to an industrialized and capitalistic economy, where the sole aim of the manufacturers was to maximise production and earn higher amount of revenue through the sales (Leonini & Santoro, 2004). It has further been observed that even though production dominated the earlier periods, in the modern era, consumer goods have gained its significance as the supreme factor which influences the purchasing behaviours of both the genders. In this context, shopping malls have replaced individual shops where the rudiments influencing consumers’ purchasing behaviour reflects immensely. Furthermore, from the perspectives of family, woman has been observed to spend thei r earnings towards fulfilling their family needs by a significant extent. Comparatively, men are generally noticed to keep aside a proportion of their earnings for their personal requirements. However, differences have aroused in situations where women are examined to be dependent on the earnings of the male members for the effective accomplishment of their family needs. Recent studies in this regard state that women are more concerned about the welfare of their family and children and thereby prefer spending for themselves after the needs of other family members have been attained. On the contrary, men have been identified to possess individualistic attitudes while considering the consumption choices (Leonini & Santoro, 2004). Emphasising on this conception, the study will evaluate the various factors that determine the consumption behaviour of both the genders. Furthermore, it will focus on identifying the relationships shared between consumption and gender analysing the ways in w hich the gender based perspectives tend to influence the consumption patterns amid customer groups. Literature Review According to Grazia & Furlough (1996), while decorating their homes, women not only focus on furnishings and attractive appliances, but also tend to consider the style and tastes of the other family members. Furthermore, women magazines, furnishings and marriage manuals have been an influencing commodity for the women consumers in deciding the consumption of its products. In relation to the modern day context, the development of departmental stores in major cities has further been observed to have re-defined the experiences of shopping for the female customers which was earlier considered as a highly-skilled task in regard to homemaking (Grazia & Furlough, 1996). However, Felski (1995) argued that although women consider themselves a prime source for decoration of households, they are the most irrational consumers, simply prone to wastefulness and extravagance when e ncountered with the attractive displays of products for sale (Felski, 1995). Thus, it can be stated that even though women are more concerned about family choices while consuming products, they are at times illogical while purchasing products, especially for the decoration purposes. This is because they cannot resist the attractive displays set up in the shopping malls which give them the opportunity to choose from a wide range of products. According to Veblen (1965), consumption is a symbolic act that evolved from the difficult distinction between ‘subordinate working people and dominant leisure classes’

What Are the Results of the Effort of the Civil Rights Movement Essay

What Are the Results of the Effort of the Civil Rights Movement - Essay Example The Southern Christian Leadership Conference started when the Montgomery Bus Boycott that began after Rosa Parks was arrested for refusing to give her seat on a bus to a white man. This incident lasted for more than a year and was pacified and ended by two prominent ministers during that time who were Ralph Abernathy and Martin Luther King Jr. The black leaders led the Southern Christian Leadership Conference from the Southern Part of the United States. The Southern Leaders Leadership Conference fought for their rights and their philosophy to uphold the rights of the African Americans not with the use of force and strength but with the use of propaganda and other forms that ensures nonviolence. Since they initially started in protecting the rights of the Black people in America, they, later on, emerged to also be involved in protecting human rights on a global scope. These people such as Luther and Aberthany along with their followers have this sense of devotion to their country the territory of their state should be equivalent to the boundaries of the nation as well as with the fact that they are proud of their color and they are confident that they have the right to live together with the other Americans. The nationalist ideology has led people to divide people in terms of â€Å"us† and â€Å"we†. The individual has no choice which group he wants to support for there are instances that ethnicity or race becomes the basis for this division. As we all know, a race is a factor we have no control of. Nationalism has this characteristic of universality wherein it establishes the claims as to how the world should be logical or arranged.

Different crops vary in their response to acid and alkaline soil conditions (Mathers, 2001). However, for most field crops, slightly acidic (pH = 5.6) to neutral soils are optimal for growth. Soil pH affects plant growth and productivity indirectly because, depending on the nutrient, availability is affected which can result in nutrient deficiency or nutrient toxicity. In higher pH or alkaline soils, result in deficiencies in the essential micronutrients iron, zinc, and manganese. Soil pH of less than 5.5 is already considered strongly acidic and will not support growth of economically important crops. Thus, the right soil pH is a requirement for maximum yield production. The development of acid soils has been due to high weathering brought about by warm temperatures and rainfall, and manmade events like the continuous use of nitrogen fertilizers and acid rain effects. At pH below 6 or under acidic soils, increased availability of micronutrients like iron, manganese, zinc , copper and aluminium result in toxicity symptoms (CSIRO Plant Industry, 2004); while decreased availability of phosphorus results in deficiency of this element . This is very true in humid countries where soil acidity is often associated with low crop productivity (Schroth, Lehman, & Barrios, 2003). The class was divided into eight groups. Each group was asked to bring soil samples from the area near their residence. In the laboratory, the pH and temperature of pure water was determined. After adding water to the soil and mixing the slurry, the pH and temperature of each sample were measured. Mean values of the soil pH of each group were determined, and the hydronium ion concentration was calculated using the

What Are the Results of the Effort of the Civil Rights Movement Essay

What Are the Results of the Effort of the Civil Rights Movement - Essay Example The Southern Christian Leadership Conference started when the Montgomery Bus Boycott that began after Rosa Parks was arrested for refusing to give her seat on a bus to a white man. This incident lasted for more than a year and was pacified and ended by two prominent ministers during that time who were Ralph Abernathy and Martin Luther King Jr. The black leaders led the Southern Christian Leadership Conference from the Southern Part of the United States. The Southern Leaders Leadership Conference fought for their rights and their philosophy to uphold the rights of the African Americans not with the use of force and strength but with the use of propaganda and other forms that ensures nonviolence. Since they initially started in protecting the rights of the Black people in America, they, later on, emerged to also be involved in protecting human rights on a global scope. These people such as Luther and Aberthany along with their followers have this sense of devotion to their country the territory of their state should be equivalent to the boundaries of the nation as well as with the fact that they are proud of their color and they are confident that they have the right to live together with the other Americans. The nationalist ideology has led people to divide people in terms of â€Å"us† and â€Å"we†. The individual has no choice which group he wants to support for there are instances that ethnicity or race becomes the basis for this division. As we all know, a race is a factor we have no control of. Nationalism has this characteristic of universality wherein it establishes the claims as to how the world should be logical or arranged.

Article Errors among Japanese Students Essay Example | Topics and Well Written Essays - 1000 words

Article Errors among Japanese Students - Essay Example It is relatable that the English articles 'a', 'an', 'zero', and 'the' often raise difficulty not to ESL/EFL learners alone, but even to learners of English as a first language. It is often found that the articles are a source of difficulty to learners as well as teachers of English as a second/foreign language and it is especially true about learners whose native languages do not have articles or do have articles or article-like morphemes which are used in ways that differ from English articles. An analysis of the morpheme acquisition by the learners of English as a foreign language confirms this difficulty with regard to the acquisition of English articles and it was found in a study by Brown (1973) that the articles 'a' and 'the' came at numbers nine and ten in the acquisition of fourteen morphemes. ... al errors in the use of indefinite articles and a focused study on the Japanese lower-intermediate tertiary level learners, as attempted in this paper, brings out some pertinent issues in the use of articles by EFL learners. One of the most obvious difficulties in the learning of English by the lower-intermediate tertiary level learners of Japan is the use of articles and an understanding of the language situation in the country provides the significant explanation for the type of difficulty with the use of articles. An important reason for the problems with the use of articles in Japanese context can be traced in the structure of the Japanese language along with other reasons. The Japanese students find it hard to follow the rules for the use of the article in English which are very complex. To explain the problem in linguistic terms, it will be particularly noted that there is no provision for the use of articles in the Japanese language. The absence of the article in Japanese raises serious trouble to the learners of English, especially in the early stages of EFL as in the case of the lower-intermediate tertiary level learners of Japan. It is also relatable in this context that Japanese language does not differentiate between singular and plural noun forms in grammar except in a few specific cases. This problem with regard to the concept of countability in grammar for the Japanese speakers also causes difficulty especially to the novice learners of English in the learning of English indefinite articles. The result of all these language differences in the use of articles is that the teacher of English in the lower-intermediate tertiary level introduces the articles to the learners as a totally new type of word and there is serious difficulty in the teaching of the

Fan Violence in International Soccer Essay Example for Free

Fan Violence in International Soccer Essay Fan violence in international soccer is a very serious form of aggression and it must be given a lot of attention by the games’ stake holders. Fan violence in international soccer involves actions that are taken by the football supporters and fights between the supporters of rival teams may sometimes take place after the football matches. The fights could also be prearranged in locations that are away from the stadiums so that the fans can avoid the police interventions. Fan violence can be at times be prompted by violent actions which involve the players themselves or any other form of event that could be taking place during a game or even disturbances and riots that are sport related and often they occur for other reasons. Fan violence in international soccer has been on the increase as it is known as the existence of an essentially unstable and an abnormal temperament in some individuals who happen for some reason to have taken soccer as an arena in which they act out their instabilities. (Smith, 1983) It has become very difficult to deal with the offenders in the football matches and the international football federation has had difficulties punishing the spectators who misbehave themselves . The international football federation has also had to deal with issues that prompt fans violence in soccer matches such as providing seats in place of standing accommodation, initiating maximum cooperation between the police and the football clubs and also ensuring that there is an absolute acceptance of the referees decisions by everybody in the football arena. The key stakeholders of the soccer game are the international football federation who ensure that the punishment that is given to the offenders and to those who participate in football hooliganism should match the seriousness of the offence. It is notably very true that the consumption of alcohol is a very important factor in crowd misbehavior especially in places where the football matches are taking place. (Smith, 1987) The football fans are mainly controlled by the activities and the popularize of different clubs . This makes it a contest as they embark on slogans chants and even songs so that they can demonstrate their support to the teams they support. The violence that exists between the sets of fans is seen as a part of their participation in the game. Violent fans and those who mainly participate in violent actions in the international soccer are basically those people who are young and unemployed. It also involves also those who are members of fanatic clubs and they are poorly educated since they attribute most of their behavior to the external factors rather than the internal ones. In most case there are usually two matches going on in a football stadium and whereas one match concerns the football teams that are on the pitch and the second match usually involves the fanatic fans whose interests are not in the game as such but on the opportunities which are offered by the football such as meeting the club mates and giving vents to their emotions and energies in the battles with others. (Smith, 1983) It is at times very complex to handle fan violence in soccer ethically since the game requires intense physical contact which may cause harm of injury. When the stake holders access the moral status of an action, they examine the issue of consent by the person on whom the action has been performed. Actions by the fans which are outside the rules of the federation of international soccer are considered to be morally unacceptabl. Reference: Smith, M.

Evaluation of Sigmund Feud and his theory

Evaluation of Sigmund Feud and his theory Sigmund Freud may have pioneered psychoanalysis and initiated interest in behavioral patterns, but some of his concepts/theories are controversial. Sigmund Freud is one of the well know scientist of his time in the area of psychology, he is intentionally referred to as the godfather of psychology. Freud was an Austrian neurologist and the founder of psychoanalysis, who created an entirely new approach to the understanding of the human personality. He is regarded as one of the most influential and controversial minds of the 20th century. Sigismund (later changed to Sigmund) Freud was born on the 6 May 1856 in Freiberg, Moravia (now Pribor in the Czech Republic). His father was a merchant. The family moved to Leipzig and then settled in Vienna, where Freud was educated. Freuds family was Jewish but was himself non-practicing. In 1873, Freud began to study medicine at the University of Vienna. After graduating, he worked at the Vienna General Hospital. He collaborated with Josef Breuer in treating hysteria by the recall of painful experiences under hypnosis. In 1885 Freud went to Paris as a student of the neurologist Jean Charcot. On his return to Vienna the following year, Freud set up his private practice, specializing in nervous and brain disorders. The same year he married Martha Bernays, with whom he had six children. Freud developed the theory that humans have an unconscious in which sexual and aggressive impulses are in perpetual conflict for supremacy with the defenses against them. In 1897, he began an intensive analysis of himself. In 1900, his major work The Interpretation of Dreams was published in which Freud analyzed dreams in terms of unconscious desires and experiences. In 1902, Freud was appointed professor of neuropathology at the University of Vienna, a post he held until 1938. Although the medical establishment disagreed with many of his theories, a group of pupils and followers began to gather around Freud. In 1910, the Intentional Psychoanalytic Association was founded with Carl Jung, a close associate of Freuds, as the president. Jung later broke with Freud and developed his own theories. After world war one, Freud spend less time in clinical observation and concentrated on the application of his theories to art, literature, and anthropology. In 1923, he published The Ego and the Id, which suggested a new structural model of the mind, divided into the Id, the Ego, and the Superego. In 1933, the Nazis publicly burnt a number of Freuds books. In 1938 shortly after the Nazis annexed Austria, Freud left Vienna for London with his wife and daughter Anna. Freud was diagnosed with cancer of the jaw in 1923, and underwent more than 30 operations. He died of cancer on 23rd September 1939. (http://bbc.com.uk/history./freud_sigmund.shtml) Freud studied hysteria at length, and became involve with Josef Breuer. Dr. Breuer became Freud mentor, and together they co-authored a book on hysteria. It was during these studies that Freud came to realize that the personality was made up of having three aspects the id, ego, and super ego, (Krogh, D.). The id is the part of personality that is responsible for survival and self gratification, it is our primitive mind. It is the source of our libido and has only one rule, satisfying the pleasure principles, (Gay, P.). The ego deals with our rational thought, it develops our growing awareness that you cannot always get what you want. It has a tough job compromising negotiation between the id and the super ego. It pleases the id but also remains responsible and bears the long term consequences in mind. The super ego is the last part of the mind to develop. It is best described as the moral of personality. The super ego has two sub systems, those been the ego ideal and conscience. The ego ideal lays down the laws regarding positive behavior and standards which the ego must live up to. The conscience are the sets of rules which define deviant behavior, it houses thoughts and behaviors that would result in punishment if they were to be acted out. Freud was also responsible for defining the five stages of psychosexual development, which are briefly explained below. Stage One: The oral stage, (0-18 months). During this stage, the physical focus is on the mouth. The young child receives libidinal pleasures while feeding. Any problems at this stage, for example, over indulgence or privation could lead the child to an oral personality in adulthood suggesting, that the adult would partake in extensive oral activities e.g. smoking, drinking, or eating disorders, (Gay, P.). Stage two: The anal stage (18-36 months). Freud believed that the child experienced erogenous pleasure while defecating. Potty training takes place round about this time, so that the child had to learn control over its bowels. Also the caregiver puts emphasis on the child to control urges regarding deviant behavior (often called the terrible twos). If the caregiver is too controlling the child is likely to grow to have a retentive personality e.g. the adult will have rigid thought complexes, be overly organized, and obsessed with neatness. On the other hand, if the caregiver is not controlling enough, the child will grow up to be messy, untidy and could possibly be defiant with little self-control, (Feldman, R, F). Stage Three: The phallic stage (3-6 years).The physical focus at this stage for both boys and girls is the penis boys wonder why girls havent got one. In return, girls start noticing that they are without one and become curious. Also during this stage, Freud suggested that children have sexual feelings for the opposite sexed parent, (so they deal with Oedipus and Electra complexes respectively). Boys experience castrations anxiety and girls suffer penis envy (the lack of). Fixation at this stage could result in promiscuity and immoral behavior, (Feldman, R,F.). Stage four: The latency stage,(6 years to the onset of puberty). This is a calm period where virtually no psychosexual conflicts are taking place. Boys and girls tend to be gender aware thorough this stage and have little in common with the opposite sex, (Feldman, R.F.). Stage five: The genital stage (post puberty). If all transitions of the above stages have been smooth and the caregiver has responded in a relevant well balanced manner. A healthy competent adult should emerge, fully equipped to contribute to society emotionally, and physically. If on the other hand, one or more of the transitions have been impaired, a fixation of the impaired stage will occur. Stress will trigger the adult to regress to the particular impaired stage in question, (Feldman, R,F). As straight forward and relevant as Freuds theories were, he was not without criticism , Carl Jung, Karl Krus et al, and T.S. Szasz are among a few who strongly object to Freuds findings (Robinson, P. Feud and his critics). Could they have a point? For all Freuds genius, he failed to incorporate genetic influences regarding behavior in his studies. Freud dealt only in the unconscious mind, with a few age related triggers thrown in, and that our whole personality is based on the development of these triggers. These triggers were purely Freuds interpretation. Behavior on the other hand, deals solely with environmental factors, and believes that babies are born as a blank slate, often termed tabula rassa Freud is also accused of been totally subjective and having a bias attitude. An example of this would be that he based all his findings on his recollections and findings (Robinson, P. Freud and his critics). He did conduct research using his youngest daughter Anna, but this form of opportunity sampling is not productive, because being his daughter, she would strive to produce socially desirable answers. When conducting psychoanalysis, Freuds patients were always middle class women. This was not a representative samples of the population, the data collected from his analysis would again be bias. Other arguments against the proficiency of Freuds practices are that due to patient Problems occurring in childhood, this may result in parental blame. There are also problems surrounding false memory syndromes, it has been found that patients receiving Freudian analysis have imagined childhood abuse. These allegations could be imagined and have no facts, (Robinson, P. Freud and his critics). Also the whole model of psychoanalysis is non-scientific, it cannot be falsified. So there we have it, the basic from which Freud conducted his psychoanalysis. In its day it was a revolution but certainly not without opposition, as previously discussed Freud managed to put words, terms, and phases to complex notions regarding personality and unravel almost simplify intricate developmental processes, enabling Freudian psychologists to accurately define and hopefully rectify a patients regressed emotional problems. Was Feud practicing a pseudo-science? Are his findings mere quackery? Were his theories on psychoanalysis a revolutionary breakthrough? Either way people will remain divided.

John B. Watson Essay -- Psychology, Behaviorism

John Broadus Watson was a famous American psychologist who lived between 1878 and 1958. He was born in Greenville, South Carolina to Pickens and Emma Watson and was the fourth of six children. The family was not well off financially and John did not have an easy childhood. In spite of the poverty that engulfed the family, John’s father turned into an alcoholic who cared less for his family. However, Emma, John’s mother was a devoted religious woman who struggled to take care of her children with less support from her husband. In 1891, John’s father left the family and disappeared after engaging in extra marital affairs with other women. The infidelity strained his marriage with Emma and the relationship with his children. After the disappearance of his father, John became unruly and confused due to the lack of full parental care of both parents. He became defiant at school and did not want to listen to advice from his teachers. He bullied fellow students and was involved in other antisocial behaviors which were quite unacceptable in the school environment, further more he became violent and even rebelled against his mother (Buckley, 1989). Watson’s negative attitude towards education did not last forever and it changed after he was accepted to Furman University where he began his training at the age of sixteen in 1894. John’s life started to turn around with his enrollment and the help of his professor Gordon Moore. He later developed a positive attitude towards academic work since he realized that he could at least now contribute to the community regardless of the social class of his family. His academic performance was quite brilliant and he graduated from Furman University with a master’s degree in 1899. He later enrolled at... ...ormation is introduced even if the previous pattern of behavior has been already established by reinforcement (Cherry, 2011). In conclusion, the theory of behaviorism is based on observable behaviors for easier quantification and data collection. Effective techniques such as behavior intervention and discrete trial training originate from this school of thought. The approaches are very essential in altering the maladaptive behaviors in adults and children (Cherry, 2011). Today, conditioning and the use of reward and punishment are used to help people learn accepted behavior and in other cases to help them stop problematic behavior (Coon & Mitterer, 2008). This has made behavior modification and training easy and possible. Therefore, Dr. John Watson played a tremendous role in the transition of psychology from the work of earlier scholars to the modern scholars.

One Flew Over the Cuckoo’s Nest and I Know Why the Caged Bird Sings Ess

One Flew Over the Cuckoo’s Nest and I Know Why the Caged Bird Sings While we can view One Flew over the Cuckoo’s Nest, from a literal perspective, as a classic story of rebellion and deliverance, we must also view it as a metaphor for one man’s triumph over of â€Å"the establishment.† The old saying, â€Å"You can’t fight city hall† is challenged, which is represented by the patients rebelling against the hospital staff. Liberals are likely to view this novel as a powerful tale that glorifies the human spirit. Conservatives are more likely to perceive it as an advertisement for social disorder and chaos. I personally thought the book’s most powerful message was that human differences should be celebrated; not censured I drew similar conclusions from Maya Angelou’s I Know Why the Caged Bird Sings. From beginning to end, this autobiography is laden with issues of racial prejudice that perpetuate self-doubt and insecurity. As early as the second page, Maya explains how she wished that she would wake up in a white world, with blond hair and blue eyes, claiming that being black was a living nightmare. There are blatant instances of racial tension throughout almost every adventure Maya experiences, including one in which â€Å" the po' white trash children† confronted Momma in front of her store. This scene culminates with Maya’s insightful realization that in spite of the disparity of power between the po'white trash and Momma, Momma had triumphed by maintaining her dignity. Eric Foner is able to dissect racial issues from an historical perspective, and show how these issues remained at the heart of the controversy surrounding the period of Reconstruction. By blending historical fact with such emotionally charged issues as race and polit... ...ess wise than true, Who thee abroad expos'd to public view..." Although part of the Puritan doctrine enforces a deep reverence for responsibility and honesty, at this point in the poem, Anne is solely blaming societal influences for her child's shortcomings. Joann Robinson faced similar personal struggles and triumphs in a more modern time. A professor at the all-black Alabama State College, Robinson was active in every level of the Civil Rights movement, even before it had officially gotten off the ground. Subsequent to her distressing experience on the bus in 1949, she tried to start a protest but was shocked and disappointed when other members of the Women's Political Council to which she belonged brushed off the incident as "a fact of life in Montgomery." Fortunately, Robinson did not feel defeated by this insipid attitude, she felt inspired by it instead.

The concentration is dependant on the proportions of hydrochloric acid and water in the solution. The stronger the hydrochloric acid is, the higher the concentration is. I know from my research that other things can affect the rate of reaction, for example:Temperature of acid- the higher the temperature of the acid is, the more energy the particles have to move around, therefore there are more collisions and so a faster rate of reaction. There is a certain amount of energy needed for the particles to react which is called the activation energy, so when the temperature of the solution is h igher, it gives more particles sufficient energy so they move faster to react when they collide more. Size of the particles- when the reactant is a solid then it can be broken down into smaller pieces or into a powder giving it different surface areas.The smaller the pieces, the bigger the surface area is and therefore there is more area for the acid to react with it, and so there is more chance of the particles colliding, so the rate of reaction will increase. Catalysts- this weakens the bonds in the reacting molecules so it seems to lower the activation energy for the reaction. This means that there can be many more successful collisions because particles will have more energy than the activation energy, and so the reaction will be faster. In order to keep my experiment fair, I must keep all the variables the same except concentration, which is what I am investigating.From my preliminarty experiments, I have found that a gas is let off in this reaction and having testing by puttin g it with lime water, I have concluded that the gas is carbon dioxide because the lime water turned cloudy. The equation is: Calcium Carbonate + Hydrochloric acid Calcium Chloride + water + carbon dioxide To find the rate of reaction, I will measure how long it takes to produce a certain amount of gas. To work out the rate of reaction, I have to divide the amount of gas I will collect with the time.Rate= amount of gas collected/ time In order to make this experiment fair, I will keep all the variables the same, except concentration. I will keep the mass of calcium carbonate the same by using one tablet each time. The masses of each tablet vary, but only by a tenth of a gram either side of 1. 01g, which I think is not a large enough difference in mass to make a difference to my experiment. I will try to do all my experiments on the same day, so the room temperature will be the same, which means the temperature of the acid will not change.I will use a burette to measure the amount of hydrochloric acid and water, so the volume of acid will be the same. I will keep the surface area the same because I will use the whole tablet and so each one will have the same surface area because they are all similar in size. Finally, I will use the same apparatus throughout my whole experiment to make it a fair test. I have done preliminary experiments in order to find the amounts I should use for the variables. I chose to collect 40cm? of gas, 50cm? of acid solution and use half a intigestion tablet and crush it.I found three problems with using this half a crushed tablet. The first problem was the fact that it did not react very strongly, and it did not collect more than 24cm? of gas with my lowest concentration of acid, secondly it was difficult to get exactly half a tablet, and this would take too long in my real experiment if I was to get exactly half a tablet each time. Lastly, I did not know when to start my stop clock, because the time delay from the first bits of calciu m carbonate falling into the acid, to the last bits of calcium carbonate falling was quite long and in between this, some gas was lost.This has made me decide to use a whole intigestion tablet, so I do not loose as much gas inbetween putting the tablet into the solution and putting the bung on the conical flask. GRAPH I decided that the lowest concentration I will use is 1M of hydrochloric acid. , which took 85 seconds to collect 40cm? of gas. This highest concentration I will use is 3. 8M of hydrochloric acid, which took 50 seconds to collect 40cm?. From my preliminary experiments I have decided to: Use one whole tablet, 50cm? of different acid concentrations and time how long it takes to collect 40cm? f carbon dioxide gas. My prediction is: The higher the concentration of hydrochloric acid, the quicker the reaction time is with the indigestion tablets. This is because I have found out that the reaction will be quicker as the concentration increases, because the higher the concentr ation is, the more particles of acid there are which are closer together to collide more with each other and therefore react with each other, and so the reaction will be quicker. This is called the collision theory.I will use a graph to show my results, and I know from previous knowledge that the graph should be directly proportional, which means as the concentration increases, so does the rate of reaction. If the concentration is doubled, the rate of reaction is doubled, because there is twice as much possibility for collisions because there are twice as much particles. The line of best fit should go through the origin because when there is no concentration of acid, there are no particles to react. I expect to get a graph which looks like the following:Equipment  · 1 burette containing hydrochloric acid  · 1 burette containing water  · 1 conical flask  · bung and deliver tube  · gas syringe  · stop clock  · clamp stand I am using burettes because they have an accuracy of 0. 1cm? which means I can measure the volumes of water and acid very accurately, and the range of the burette is 0-50cm? of liquid, which is enough for what I need. I will use a gas syring which is accurate to 1cm? of gas collected, and ranges from 0-100cm? of gas which is accurate enough if I am to collect 40cm? of gas.The stop clock is accurate to the 100th of a second, but I will round the time to the nearest second, because it is more realistic when remembering human reaction times, which is about 0. 1 seconds. In order to not let any gas escape, I will make sure I put the delivery tube and gas syring securely together. Method  · Set up apparatus as above  · Take 50cm? of the following concentrations at one time, using the burettes of acid and water-1M, 1. 4M, 1. 8M, 2. 2M, 2. 6M, 3. 0M, 3. 4M, 3. 8M.  · Put the acid solution into a conical flask  · Put 1 intigestion tablet into the the acid and put the bung on. Start the stop clock and time until the marker reaches 40cm?.  · Do this for all the concentrations. I will use a range of 2. 8M of hydrochloric acid, the lowest concentration is 1M and the highest is 3. 8M. I decided to use these concentrations, because in my preliminary experiments, I saw that the reaction was too slow with a concentration below 1M, and that the reaction would be too fast above 3. 8M. I have chosen to do 8 different concentrations, because I will not have enough time to do more, and I will still beable to draw a concusion even if I only use 8 different concentrations.I will have to use both 2M and 4M hydrochloric acid in order to make the different concentrations of acid. The ones which are 2M or below I will make with the 2M hydrochloric acid, and for the rest 4M hydrochloric acid. I will try to use as little of the 4M acid as possible, because it is more dangerous than the 2M. I will take as many repeat readings as I can in the time that I have, because repeats will help me to make sure I do not get any anomalous results. I will reapeat the anomalous results first. The more repeats I do, the more reliable my results will be.Safety I will use 2M and 4M hydrochloric acid which both have IRRITANT warnings so I will be careful using them and try not to get them on my hands or in my eyes. I will use goggles to protect my eyes. GRAPH Results This conclusion supports my prediction well because my results show that the higher the concentration, the quicker the reaction is because there are more particles to react with each other, and so there is more chance for them to collide and therefore the reaction is faster, which is what I originally assumed in my prediction.My graph shows it is directly proportional, because if I take the concentration of 1. 5M of hydrochloric acid, and find the rate of reaction using my graph, it shows that the rate of reaction is 0. 36 cm? /s, and using the graph if I double the concentration to 3M, the rate of reaction is 0. 72 cm? /s which is exactly two times faster tha n the reaction with 1. 5M which shows it is directly proportional. In the following table, I have calculated the average time and rate of reaction for all the different concentrations.I have then worked out the difference between each rate in order to find if there is a trend in how much quicker the reaction is which each concentration. GRAPH From this table, I can see there is a trend, because as the concentration goes up by 0. 4M each time, the rate goes up by 0. 07, 0. 08 or 0. 09 cm? /s which are very close to each other and shows that the rate is quite consistent because no matter what the concentration is, the rate goes up in a certain way on average of 0. 08 cm? /s. The only results that do not go with trend are the 3. M concentrations. On my graph I have circled them as anomalous results. There can be several explanations for this which I will cover in the evaluation. The following diagram is a simple way to help show why the rate of reaction increases with the concentration : My experiment has helped me with my conclusion that the rate of reaction increases as the concentration of the hydrochloric acid increases, and has given me evidence to help explain it. Evaluation My results are as realiable as I could make them using the apparatus and the time I had.From my results I can say that most of the results are quite reliable and accurate to what they should be because I got the results I expected. However, I did get two results which I would say are anomalous. I decided that these two results are anomalous because according to my background knowledge and the rest of my results, I knew that I should get a directly proportional line of best fit, and the rest of the results are very near to this line of best fit. I know that my line of best fit is correct because as the concentration doubles, the rate doubles.The results for the 3. 8M showed that the rate was slower than the rate of reaction with a lower concentration of 3. 4M. There are many different fac tors which may have affected my results. One of the biggest faults in my experiment was the fact that I did not have enough time to complete it in one day. Due to various problems, I had to do the experiment on three different days. This means that all the equipment was different which may mean that they work differently from eachother. This makes it an unfair test.The second problem with doing it on different days is the problem of room temperature which can have a big effect on the rate, because as I know from back ground knowledge, I know the warmer the acid is, the faster the reaction because particles have more energy so there are more successful collisions. I made the mistake of not recording which results are from which day, so I cannot tell if this had a major effect on the results. Whilst doing the experiment, I noticed a few problems which may also have effected my results.First of all is the problem that I only have two hands, so it was difficult to put the tablet in the conical flask, close the bung and also start the stop clock, all at the same time. When there was someone available, I asked them to start my stop clock, but this was not possible all the time. Adding this time to human reaction time of around 0. 1 of a second, some time could have been lost. Some gas was also lost in the time period between putting the tablet in and putting the bung on. I tried my best to make this time period very small, but still some gas was lost.When I had managed to get the tablet into the acid with the bung on and time it, I noticed that sometimes the whole tablet would not go into the acid, and so it was not all reacting, so in order for the whole tablet, I would shake it for a couple of seconds. I did not count how long I would do this for each one, but when I did shake it a lot of gas would be produced, so If I shook one flask for longer, more gas would be produced faster because the whole tablet would be reacting with the acid and there would be more coll isions and therefore a quicker reaction.Between each different concentration, I would wash the conical flask, and I observed that if I washed the flask with hot water, the flask would become hotter, or if I washed it with cold water the opposite would happen. This meant that the temperature of the acid and water solution would vary. This made the tests unfair because if I did some of them with hot conical flasks and others with cold ones, the ones with the warmer flasks would react faster because the temperature of the acid would increase and so give the particles more energy to react.If the equipment was much more sophisticated, for instance if all the equipment would stay the same temperature or if there was special clock which would start at the exact time the tablet touched the acid, my results would be much more accurate, but I still found good results. [IMAGE]If I could do the experiments again, I would do the following things differently in order for my results to be more acc urate.I would make sure I did them all on the same day, use all the same equipment, have someone to start the stopclock, have better equipment, for instance a conical flask with a divider so the acid and calcium carbonate won't mix until I want them to: Apart from all of the problems, my method was suitable and the experiment was successful because I had sufficient evidence to enable myself to come to a conclusion which agreed with my knowledge and prediction. I would have liked to share results with other people who were doing the same experiment as me to see if our results were similar, but nobody was doing the same experiment as me.The only results which I did not think are reliable or accurate is the reaction of the 3. 8M concentration of hydrochloric acid with the calcium carbonate, and if I had more time I would investigate this further. I would find out why these results were anomalous because even though I did reapeats, I still got anomalous results and so I would like to fi nd out why this happened. I would like to investigate the rate of reaction with more concentrations in order to see what happens after 3. 8M acid to see if it was still directly proportional or if the graph leveled off.Other extra investigations I would do would include using different types of acid for instance nitric acid or sulphuric acid and see if they changed the reaction at all. I would also try and use different types of indigestion tablets, because the ones I used contained ginger which I have researched about to find that it is used for digestion, soothing aches and pains in muscles and improves circulation problems, so I would like to investigate if this has a different effect on the rate of the reaction or not.I put an indigestion tablet into 1M of acid concentration and measured the temperature before and after the reaction for one minute to see if the reaction was exothermic or endothermic, but there was no change in temperature, so I would like to see what effect an e xothermic or endothermic reaction would have on the experiment. Overall I think my results are reliable because the repeats are all very close to eachother, the biggest gap between my repeats is the 1. M concentration which had a time difference of 6 seconds, but the others which I had time to repeat are all around 3 seconds apart. If I had more time I would do much more repeats to make my results more reliable. The accuracy of my results are quite good because they are all very close to the line of best fit. I would like to do more experiments and repeats to make sure my line of best fit is accurate and in the correct place. Apart from these I think my investigation was successful.

Bicyclists and motorcyclists should be required by law t Essay

Bicyclists and motorcyclists should be required by law t - Essay Example When motorcycles and bicycles are involved in any accidents, the physical body of the human could be injured particularly the head or the brain part, leading to death and even if an individual survives, the life will be a living hell. This brings into the picture the importance of helmets and how helmets could save a person from death or from becoming a ‘Vegetable’. This being in argument, the other is how many motorcyclists and bicyclist are driving without helmets with a lot of comfort, and how helmets could cause accidents. Thus, this paper will focus on the role of helmet and how it can be a lifesaving tool on one side and how it is not such a lifesaving tool and could give discomforts on other side. Helmet worn by motorcyclists and bicyclists brings in a lot of advantages and importantly saves a lot of lives. That is, as helmets are like a strong armor for the head, any strong and dangerous impacts during an accident can be absorbed by the helmets. In most of the accidents and incidents involving motorcycles and bicycles, the riders will separate from the vehicle and the head of that individual will normally make a strong impact on other strong objects like the other vehicles, roadside objects and even the strong road. That impact could damage or break the skull leading to the damage to the brain resulting in death. Motorcyclists usually separate from the motorcycle at some time during a crash. It stands to reason that protective apparels like helmets are far more likely to be effective than protective equipment attached to the motorcycle In the event of a crash, no existing strategy or safety equipment offers protection comparable to a FMVSS 218 compliant helmet. (NHTSA). Helm eted riders have shown significantly lower injury impacts in all types of lesions in the body particularly in the head. A recent analysis from the Crash Outcomes Data Evaluation Systems (CODES) from six states demonstrated that helmets were 35 percent

Strategic Management in Singapore Airlines Research Paper

Strategic Management in Singapore Airlines - Research Paper Example This research report introduces airline industry in general and Singapore Airline in specific. It includes a brief history of the company. However, the focus is on the mission and vision of the company and on the profile of Board of Directors, which run the strategic management of the company. Current marketing strategy of the company is also under discussion. Introduction Air travel is an essential requirement of today’s global world. It provides its users with an easy, fast, and comfortable mode of travel. However, with the economic and social development of the world resulting in almost every developed country launching its international airline, air travel has become an option with considerably large number of choices. Every airline is competing with other airlines to enlarge their customer base on bases of airfare, comfort, services, and travel route. In this competitive environment, the name of â€Å"Singapore Airline† holds a lot of worth. The airline from its la unch until today has grasped a huge share of international air travelers due to its excellent and expert services. The airline with its slogan â€Å"a great way to travel† works hard to provide its customers with the promised experience of excellence. The company describes itself as â€Å"Singapore Airlines has evolved into one of the most respected travel brands around the world. We have one of the world's youngest fleet in the air, a network spanning five continents, and the Singapore Girl is our symbol of quality customer care and service. Customers, investors, partners, and staff — everyone expect excellence of us† (Singapore Airline, 2012). History On 28 January 1972, the Singapore government founded Singapore airline (SIA). It was incorporated as a limited liability public company, completely owned by the Singapore government (Singapore Investor Association, 2006). â€Å"The history of the company dates back to 1947 with the initiation of a scheduled serv ice of Malayan Airways Ltd between Singapore and Kuala Lumpur† (Singapore Airlines, 2012). With the addition of international services and formation of â€Å"Federation of Malaysia in 1963,† the airline acquired the new name of â€Å"Malaysian Airways Ltd† (Singapore Airlines, 2012). Government of Malaysia and Singapore in 1966 acquired joint control of the airline and renamed it to â€Å"Malaysia- Singapore Airline Ltd† (Securities Investor Association, 2006). However, MSA in 1971 was restructured in to two entities: Malaysia Airline System Bhd and SIA (Singapore Airlines, 2012). Mission Singapore airlines describe its mission through its mission statement. The mission statement clearly identifies the main objectives of the company. The statement is as follows: â€Å"Singapore Airlines is a global company dedicated to providing air transportation services of the highest quality and to maximizing returns for the benefits of its shareholders and employeesà ¢â‚¬  (Singapore Airline, 2012) Vision The company considers itself a citizen of the world and aims to excel not only as an excellent company but also as an excellent and responsible citizen of the world. It aims to fulfill this mission, which it believes to be actually its responsibility by enhancing the lives of the people they come in contact with. This is the reason that the company has made numerous commitments to the art, education, communities and health and welfare of their countries’ citizens and of those countries it flies to. It also feels a strong sense of responsibility towards the environment, and so holds a strong commitment towards environment preservation for the future generation (Singapore Invest
