A Seperate Piece Essay essays

A Seperate Piece Essay essays I would say that Finny(Phineas) was the biggest idealist in the story. His feelings and many things on many issues, made me think of him this way. The actions that Finny take in the novel make him seem as though he is the happiest person on the planet, like for instance when he says "There is no war", this showed that he wasn't really bothered by the war which during that time period I believe it meant happiness. Finny also never lost faith in his so called friend Gene even though I think he knew in the back of his mind that Gene was against him the whole time yet also admired him at the same point. Finny was spontanious person like the first time they jumped off the tree, and when he broke the school swimming record. Even with all of this Finny couldn't seem to take it upon himself to believe certain things like, Gene breaking his leg, or there not being a war. Although after breaking his leg however Finny is faced with his own personal struggle the bitterness of being a cripple an d attempting to live in a world where sports and enlistment in the army are no longer a possibility. I think the second time Finny broke his leg he came to be one with the reality that he was in fact ruined, and that most of it was caused by Gene, and Gene's ill-will toward him, which caused him to be cripple in the first place. Yet Finny still thought to see his dreams out, only this time through Finny, he said things like Gene i'm going to start conditioning you for the olympics, and so forth and so on. Finny in all cases was the "Idealist" of the story, one of the close contenders was Leper though, yet Finny still was more idealistic. Gene(Narrator) is the most realistic in the novel, yet in a few ways he is also idealistic, but never the less still the realist of the story. His look on life is that there is a war but not a war on far away battle fields a war on the homefront, with being competitive ...

Definition and Examples of Modality in Grammar

Definition and Examples of Modality in Grammar In grammar and semantics, modality refers to linguistic devices that indicate the degree to which an observation is possible, probable, likely, certain, permitted, or prohibited. In English, these notions are commonly (though not exclusively) expressed by modal auxiliaries, such as can, might, should, and will. They are sometimes combined with not. Martin J. Endley suggests that the simplest way to explain  modality  is  to say that it has to do with the stance the speaker adopts toward some situation expressed in an utterance...[M]odality reflects the speakers attitude toward the situation being described (Linguistic Perspectives on English Grammar, 2010). Deborah Cameron illustrates with an example: [Modality] is what makes the difference between a factual assertion like  unicorns never existed, and a more guarded view, such as  it seems unlikely that unicorns could ever have existed- or a bolder claim like  the existence of unicorns must always have been a myth.  Modality, then, is a resource  speakers  and writers use when they are staking claims to knowledge: it allows them to formulate different kinds of claims (e.g., assertions, opinions, hypotheses, speculations) and indicate how committed they are to those claims. (The Teachers Guide to Grammar, Oxford University Press, 2007) Indicating Modality Grammatically Just as tense indicates a time aspect of a verb, words that are used to show modality indicate the mood of the sentence- that is, how factual or assertive the statement is- and it can be done in any number of ways, including with adjectives. Martin J. Endley in Linguistic Perspectives on English Grammar  explains: Thus, a situation might be described as  possible, probable, necessary, or  certain. The  noun  counterparts of these adjectives also express modality so that a situation can be described as a  possibility, a  probability, a  necessity, or a  certainty. Moreover, it is possible to use ordinary  lexical verbs  to convey modality....And think  about the difference between saying that you  know  something and saying that you  believe  something. Such differences are essentially a matter of modality. Finally, English also contains certain semi-fixed lexical phrases (e.g.,  rumor has it) that are, basically, modal expressions.  (IAP, 2010) Other terms that express modality are marginal modals, such as need, ought to, dare, or used to. In Depth: Types of Modality The range of possibilities expressed when using modality is a broad spectrum, ranging from not very likely to very likely; to express these different levels, modality comes with named gradations, as explained by authors  Gà ¼nter Radden and Renà © Dirven, in Cognitive English Grammar:   Modality is concerned with the speakers assessment of, or attitude towards, the potentiality of a state of affairs. Modality, therefore, relates to different worlds. Assessments of potentiality, as in You must be right, relate to the world of knowledge and reasoning. This type of modality is known as epistemic modality. Modal attitudes apply to the world of things and social interaction. This type of modality is known as root modality. Root modality comprises three subtypes: deontic modality, intrinsic modality and disposition modality. Deontic modality is concerned with the speakers directive attitude towards an action to be carried out, as in the obligation You must go now. Intrinsic modality is concerned with potentialities arising from intrinsic qualities of a thing or circumstances, as in The meeting can be canceled, i.e. it is possible for the meeting to be canceled. Disposition modality is concerned with a things or a persons intrinsic potential of being actualised; in particu lar abilities. Thus, when you have the ability to play the guitar you will potentially do so....Modal verbs have a special status among modal expressions: they ground a situation in potential reality. (John Benjamins, 2007)

There is a fundamental problem of the current systems as they cannot integrate and share information with each other. According to Jean Roberge, the vice president of IT at ABS Canada, the required system should be able to integrate the management system for the development of the entire organisation. The adoption of the new system presents various management issues that include the technological changes making some of the current approaches become obsolete. There is an imminent change in the direction of IT management at the company following the implementation of the proposed system. This will change the roles performed by Roberge, hence he needs to find someone who can assist in performing the various activities arising after adopting the new system. The process of getting an assistant to Roberge is a fundamental challenge that is threatening the implementation of the proposed system Understanding the situation remains essential towards gaining insight and consequently getting the solution to the problem facing the organisation. It is essential to make a consideration of the organisational capabilities regarding information technology in seeking to ascertain the possible solutions to the problem identified. Roberge should conduct an Emerging Issues Analysis in seeking to understand the concerns which might arise in future and develop a strategic plan for the future (Kloppenborg, 2014). This would involve brainstorming with fellow employees whom he feels can provide support in finding solutions to the problem. Since technological change remains inevitable, there is need for Roberge to conduct training of fellow employees through the consultants who have been involved in making the proposals. This will enhance the knowledge of

Financial Analysis Report Essay Example | Topics and Well Written Essays - 1250 words

Financial Analysis Report - Essay Example The auto industry is one of the largest and most profitable industries in the world. There are over one billion vehicles worldwide and in the United States there are approximately 240 million cars (Tencer, 2011). These vehicles often breakdown and require maintenance. Due to the massive amount of vehicles in the United States there is a huge demand for auto parts. One of the biggest players in the auto parts industry is AutoZone. AutoZone has been in business for over 30 years. The organization was founded in 1979. The company is committed to providing the best parts, prices and customer service in the automotive aftermarket industry (Autozoneinc, 2012). The company believes in the value of providing great service in order to increase its customer retention rate. Based on Pareto’s 80/20 rule firms obtain 80% of their business from 20% of their customers (Hafner, 2001). AutoZone is a publicly traded company sold in the New York Stock Exchange under the symbol AZO. The stock as of August 3, 2012 was selling at a price of $360.33 (Yahoo). The firm began to sell its stocks in the open market in 1991. The market capitalization of the company is $13.71 billion. Market capitalization is calculated by dividing total stocks outstanding by market price. The company is a member of the Fortune 500. The fact that AutoZone is a publicly traded company gives this firm an advantage in this industry due to the fact that the company always has the option of releasing a secondary stock offering to raise capital. The auto parts industry is extremely fragmented with thousands of independent auto parts stores across the nation. AutoZone has grown a lot since its inception 33 years ago. The company today is the market leader in the auto parts industry in the United States of America. The corporate headquarters of AutoZone are located at 123 S. Front St. Memphis, TN 38103 (Ecorporateoffices, 2012). The auto parts chain

My Life Learning Experience with R.S.V Essay Example for Free

My Life Learning Experience with R.S.V Essay R. S. V My Life Learning Experience with R. S. V Name Course Title Teacher Date Abstract Many individuals have experienced problems with their hospitals or health care facilities. An important concept that I learned from facing this family crisis that will be examined in this paper is that, when a family member becomes seriously ill, they need quality medical care. Sometimes, when a persons life is at stake, the further a person lives from medical facilities which can offer quality care can be a grave factor. R. S. V 1 R. S. V in Infants This paper will examine several lessons and concepts which I learned from personal life-learning experiences. Three examples that will be addressed in this paper will examine a different aspect of a certain life-learning experience. In researching and analyzing each aspect of a life-learning experience, this paper will examine the four elements of Kolbs Model of Experimental Learning. The first aspect of the lessons I learned after enduring a family crisis which this paper will explore includes how I learned about an illness that frequently affects infants called Respiratory Syncytial Virus. Respiratory Syncytial Virus, or RSV, is a respiratory virus which has many of the same symptoms as the common cold and is usually contracted by children during winter months. After my newborn son, Carter Forrest Barnhart began displaying symptoms of a common cold, my husband and I took Carter to his local pediatrician. Unfortunately, the pediatrician improperly diagnosed the virus as a simple common cold and sent Carter, my husband and I back home. However, after we returned home, his symptoms did not improve. Instead, he began coughing profusely and did not want to eat. I became greatly concerned about our sons health. Within a few days, Carter had lost weight and become weak. Then his breathing appeared to be abnormal, and my husband and I began to suspect that something else was wrong with Carter. R. S. V 2 By April 7th, 2002, Carters breathing problems got considerably worse, and my husband and I thought that he could possibly suffocate. So, in a desperate attempt to help Carters health, we brought our son to the nearest hospital. He was then hospital, arrangements needed to be made to send him to Charleston Area Medical Center. Carter later arrived safely at the Women and Childrens Hospital, a division of the Charleston Area Medical Center in Charleston, West Virginia. He was then placed in the hospitals Pediatric Intensive Care Unit, where he remained for five days. Looking back, I now realize the high importance of residing in communities which have high quality health care facilities. I learned that the first doctor who diagnosed my son did not diagnose Carter properly by failing to recognize that what looked like the common cold was actually Respiratory Syncytial Virus (RSV). The pediatricians error could have cost my son his life. After Carter was taken to the emergency room at our local hospital, I learned that, when someones life is at stake, the distance from a medical facility which can provide quality care is sometimes a life and death matter. Thus, one of the lessons that I learned by this life-learning experience is that it is important for all individuals to have quick access to a state of the art hospital or medical facility. A medical facility must be able to provide the excellent care that a seriously ill R. S. V 3 ndividual needs. In this example, a baby needed to be treated by a special infant care unit, which our local hospitals did not have. Therefore, the baby did not have ready access to the kind of medical facility that he needed. The proper medical facility can mean the difference of life or death, thus, I now understand that the quality of the medical facilities, and the services received from those facilities provided, is one of the important issues facing people today. Learning about the importance of living near a high quality health care facility helped me become amiliar with the idea that a person should be fully educated about the health services in his or her community before something critical occurs. I regretted the fact that we were not more prepared to deal with this crisis. Thus, I have since learned that I need to research the qualifications of any professional my child will be receiving treatment from. In the future, I will research hospitals or schools before enrolling my child in them. I can also apply the concept that quality care is an important aspect of a persons life to other situations as well. For example, I will have o make sure that my child has a qualified pediatrician and dentist to take care of his health needs in the future. I will also have to ensure that my child gets his vaccinations. Moreover, I learned that there is no substitute for being prepared for an emergency situation. I plan on researching the response time of our police and fire departments and plan to learn about the efficiency of our ambulance services. Another part of the lessons I learned while confronting this family crisis is how I learned that high quality heath care is best provided by highly qualified doctors. I lso learned that an unqualified doctor may easily misdiagnose a patients symptoms. The discussion below will show how I have learned to ask questions before selecting a pediatrician. My son was initially treated by a pediatrician who misdiagnosed the babys medical symptoms and declared that our infant was we were told to take our child home and give him some cold medicine. This was our childs only treatment, and the medicine did not work. Carters symptoms did not improve after a reasonable period of time. Thus, my husband and I began to suspect that something else could be wrong. Then, when our baby turned pasty in color, started to cry inconsolably, refused to eat or drink anything, lost weight, and then hardly cried or moved in his crib, my husband and I became more concerned. We later learned that Carter had RSV and double pneumonia. Since then, I have spoken to many doctors about rural medicine. One of the doctors I spoke to that works at our local hospital explained in a recent personal interview which I conducted with him that many people do not ask enough questions of their doctors after they have been told the results of a diagnosis. He advised that potential atients should ask about all terms that describe the problem and that the doctor should fully explain the R. S. V 5 condition to the patient. More importantly, when the patient is a baby, the infants parents need to understand the complete diagnosis of their childs condition The doctor also said that a great deal of rural patients do not know how to properly ask their doctors specific questions related to the diagnosis. Therefore, rural doctors need to take more time to explain things to their patients, especially in cases where doctors are not absolutely sure of the diagnosis. I was also told that some patients have no reason to be told when something is misdiagnosed as nothing more than the common cold, especially when a childs doctor confidently tells an infants parents that the symptoms should improve when the baby took the cold medicine. The lesson is that parents must be very careful when choosing a pediatrician. I learned that a good pediatrician knows how to check a baby for a variety of diseases. In the case of my son, the first pediatrician failed to properly diagnose the baby because he was, at the very least, was not familiar with the symptoms of RSV. Thus, I learned that receiving treatment from a qualified pediatrician is an essential part of a childs health care. I also realized, in other areas of my life, I need to be certain that I am qualified to perform any Job that I might later want to undertake. So it is imperative that I take my education as serious as possible so that I will later be prepared to succeed in my chosen career. R. S. V6 Another important concept that I learned through my life-learning experience is that Just like other people, doctors make errors too. Unfortunately, a doctors mistake can cause the loss of ones life. Any professional should avoid making unnecessary mistakes at all times. Therefore, I would like to avoid making mistakes which would be considered negligence in my chosen career. Thus, I now believe that I need as much training in the field of health care management as possible, because that is the field which I intend to begin my professional career once I have received my Bachelors Degree. I also now would like to become actively involved in professional organizations and associations in which school friends and successful will help me exchange information with other health care management professionals hich will hopefully help me keep atop of current developments in my field. The third aspect of the lessons I learned which this paper will explore is that many rural health care facilities in America do not have up to date equipment. I also learned that, for the past several years, many local family health care facilities have suffered from recent cutbacks in federal grant money. This paper will now discuss my findings about the importance of selecting a health care facility which has up to date equipment and employees that keep on top of current developments in the medical ield. R. S. V7 Not only were the doctors more knowledgeable at the Women and Childrens Hospital in Charleston, but the doctors at the hospital in Charleston also had more current equipment and also performed their duties much more quickly and efficiently than the doctors at the local hospital. I learned that, when the life of a loved one is at stake, a hospital with modern equipment and trained staff can mean the difference between life and death. I also now believe that parents should visit the local hospitals before their first child is ever born to make sure those hospitals re not understaffed, dirty, or not funded properly. While larger hospitals may charge more money for visits, the money paid for a proper diagnosis at a quality facility is far less than the money one might pay if an illness is misdiagnosed. In addition, local medical care facilities need to provide quality, up to date services to their patients. In this situation, Carter needed to be treated in a special care unit in which patients are attached to electronic monitors which track vital functions as well as to other equipment that support breathing (Roberts, 1993, p. 170). Unfortunately, only larger acilities usually have modern pediatric intensive care units, and large hospitals are not all cities. I have learned that a high quality health care facility should have up to date equipment. Modern equipment is essential to provide patients with the best possible R. S. V8 health care. However, a lot of rural hospitals cannot afford this. The issue of a facility which does not have modern equipment is a very important one, and the concept applies to other situations which I may have to deal with later on. For instance, I will want to make sure that, any school my child is enrolled in should have adequate acilities. I will want to ensure that the school has smoke detectors in every classroom and that the fire extinguishers are in proper working order. This paper analyzed the various lessons and concepts that I learned from some life-learning experiences. Each of the papers three parts explored a different aspect of my experiences. This paper used the four elements of Kolbs Model of Experimental Learning to detail how I used the lessons during a family crisis. R. S. V9 References Mesa, CA: ICN Pharmaceuticals. Roberts, M. J.

Essay on Attempts to Communicate in The Yellow Wallpaper

Attempts to Communicate in The Yellow Wallpaper Human nature is complex. Its requirements to remain healthy supersede those basic needs of food, shelter, and clothing. It is human to desire attention, companionship, to communicate heart-felt sentiments, and to be understood. In order to acquire self-esteem and to battle loneliness, one naturally searches to have these desires satisfied. Charlotte Perkins Gilman vividly illustrates these human aspirations in The Yellow Wallpaper. Subsequently she paints a horrific picture of someone who fails in her quest. These elements of this short story render it to be, for any reader who has experienced these hungers, an intensely personal experience. The heroine of this tale knows that she is not well, and the fact that medical authorities contradict her self-diagnosis frustrates her. She concedes that her husband should be more knowledgeable than her about her condition. This undermines her self-confidence in being able to evaluate herself. "If a physician of high standing, and one's own husband, assures friends and relatives that there is really nothing the matter with one but temporarily nervous depression - a slight hysterical tendency - what is one to do?" Another acceptable title for this short story could be "John says". Many of her feelings and much of her behavior are reactions to what John says. Her attempts to assuage her anxiety generally meet opposition by her husband. She offers suggestions to remedy her condition: "- But John says the very worst thing I can do is to think about my condition, and I confess it always makes me feel bad." She expresses her uneasiness about the house: "...but he said... ... more careful! Did not that sound innocent? But I know she was studying that pattern, and I am determined that nobody shall find it out but myself!" And she is prepared to protect her world even if it requires resorting to violence: "But I am here, and no person touches this paper but me, - not alive!" The Yellow Wallpaper is poignant. The heroine is in desperate need of attention, a need that is never adequately met. Although the dramatization of her development may appear extreme, considering the fact that she probably had a preexisting condition of mental instability permits the outcome to be acceptable. Although the average reader may not be able to relate to the demise of the heroine, most can understand the frustration and anxiety which accompany restrictions, the feeling of not being understood, insecurities and loneliness.

Structure of Language

he Structure of Language Language is a system of symbols and rules that is used for meaningful communication. A system of communication has to meet certain criteria in order to be considered a language: A language uses symbols, which are sounds, gestures, or written characters that represent objects, actions, events, and ideas. Symbols enable people to refer to objects that are in another place or events that occurred at a different time. A language is meaningful and therefore can be understood by other users of that language.A language is generative, which means that the symbols of a language can be combined to produce an infinite number of messages. A language has rules that govern how symbols can be arranged. These rules allow people to understand messages in that language even if they have never encountered those messages before. The Building Blocks of Language Language is organized hierarchically, from phonemes to morphemes to phrases and sentences that communicate meaning. Phon emes Phonemes are the smallest distinguishable units in a language.In the English language, many consonants, such as t, p, and m, correspond to single phonemes, while other consonants, such as c and g, can correspond to more than one phoneme. Vowels typically correspond to more than one phoneme. For example, o corresponds to different phonemes depending on whether it is pronounced as in bone or woman. Some phonemes correspond to combinations of consonants, such as ch, sh, and th. Morphemes Morphemes are the smallest meaningful units in a language. In the English language, only a few single letters, such as I and a, are morphemes. Morphemes are usually whole words or meaningful parts of words, such as refixes, suffixes, and word stems. Example: The word â€Å"disliked† has three morphemes: â€Å"dis,† â€Å"lik,† and â€Å"ed. † Syntax Syntax is a system of rules that governs how words can be meaningfully arranged to form phrases and sentences. Example: On e rule of syntax is that an article such as â€Å"the† must come before a noun, not after: â€Å"Read the book,† not â€Å"Read book the. † Language Development in Children Children develop language in a set sequence of stages, although sometimes particular skills develop at slightly different ages: Three-month-old infants can distinguish between the phonemes from any language.At around six months, infants begin babbling, or producing sounds that resemble many different languages. As time goes on, these sounds begin to resemble more closely the words of the languages the infant hears. At about thirteen months, children begin to produce simple single words. By about twenty-four months, children begin to combine two or three words to make short sentences. At this stage, their speech is usually telegraphic. Telegraphic speech, like telegrams, contains no articles or prepositions. By about age three years, children can usually use tenses and plurals.Children’ s language abilities continue to grow throughout the school-age years. They become able to recognize ambiguity and sarcasm in language and to use metaphors and puns. These abilities arise from metalinguistic awareness, or the capacity to think about how language is used. Ambiguous Language Language may sometimes be used correctly but still have an unclear meaning or multiple meanings. In these cases, language is ambiguous—it can be understood in several ways. Avoid biting dogs is an example of an ambiguous sentence. A person might interpret it as Keep out of the way of biting dogs or Don’t bite dogs.Theories of Language Acquisition The nature vs. nurture debate extends to the topic of language acquisition. Today, most researchers acknowledge that both nature and nurture play a role in language acquisition. However, some researchers emphasize the influences of learning on language acquisition, while others emphasize the biological influences. Receptive Language before E xpressive Language Children’s ability to understand language develops faster than their ability to speak it. Receptive language is the ability to understand language, and expressive language is the ability to use language to communicate.If a mother tells her fifteen-month-old child to put the toy back in the toy chest, he may follow her instructions even though he can’t repeat them himself. Environmental Influences on Language Acquisition A major proponent of the idea that language depends largely on environment was the behaviorist B. F. Skinner (see pages 145 and 276 for more information on Skinner). He believed that language is acquired through principles of conditioning, including association, imitation, and reinforcement. According to this view, children learn words by associating sounds with objects, actions, and events.They also learn words and syntax by imitating others. Adults enable children to learn words and syntax by reinforcing correct speech. Critics of t his idea argue that a behaviorist explanation is inadequate. They maintain several arguments: Learning cannot account for the rapid rate at which children acquire language. There can be an infinite number of sentences in a language. All these sentences cannot be learned by imitation. Children make errors, such as overregularizing verbs. For example, a child may say Billy hitted me, incorrectly adding the usual past tense suffix -ed to hit.Errors like these can’t result from imitation, since adults generally use correct verb forms. Children acquire language skills even though adults do not consistently correct their syntax. Neural Networks Some cognitive neuroscientists have created neural networks, or computer models, that can acquire some aspects of language. These neural networks are not preprogrammed with any rules. Instead, they are exposed to many examples of a language. Using these examples, the neural networks have been able to learn the language’s statistical s tructure and accurately make the past tense forms of verbs.The developers of these networks speculate that children may acquire language in a similar way, through exposure to multiple examples. Biological Influences on Language Acquisition The main proponent of the view that biological influences bring about language development is the well-known linguist Noam Chomsky. Chomsky argues that human brains have a language acquisition device (LAD), an innate mechanism or process that allows children to develop language skills. According to this view, all children are born with a universal grammar, which makes them receptive to the common features of all languages.Because of this hard-wired background in grammar, children easily pick up a language when they are exposed to its particular grammar. Evidence for an innate human capacity to acquire language skills comes from the following observations: The stages of language development occur at about the same ages in most children, even though different children experience very different environments. Children’s language development follows a similar pattern across cultures. Children generally acquire language skills quickly and effortlessly. Deaf children who have not been exposed to a language may make up their own language.These new languages resemble each other in sentence structure, even when they are created in different cultures. Biology and Environment Some researchers have proposed theories that emphasize the importance of both nature and nurture in language acquisition. These theorists believe that humans do have an innate capacity for acquiring the rules of language. However, they believe that children develop language skills through interaction with others rather than acquire the knowledge automatically. Language, Culture, and Thought Researchers have differing views about the extent to which language and culture influence the way people think.In the 1950s, Benjamin Lee Whorf proposed the linguistic re lativity hypothesis. He said language determines the way people think. For example, Whorf said that Eskimo people and English-speaking people think about snow differently because the Eskimo language has many more words for snow than the English language does. Most subsequent research has not supported Whorf’s hypothesis. Researchers do acknowledge, however, that language can influence thought in subtle ways. For example, the use of sexist terminology may influence how people think about women.Two ways that people commonly use language to influence thinking are semantic slanting and name calling. Semantic Slanting Semantic slanting is a way of making statements so that they will evoke specific emotional responses. Example: Military personnel use the term â€Å"preemptive counterattack† rather than â€Å"invasion,† since â€Å"invasion† is likely to produce more negative feelings in people. Name Calling Name calling is a strategy of labeling people in order to influence their thinking. In anticipatory name calling, it is implied that if someone thinks in a particular way, he or she will receive an unfavorable label.Example: On the day a student buys a new desk, he might say, â€Å"Only a slob would pile junk on a desk like this. † This might help ensure that his roommate keeps it free of junk. Bilingualism Although people sometimes assume that bilingualism impairs children’s language development, there is no evidence to support this assumption. Bilingual children develop language at the same rate as children who speak only one language. In general, people who begin learning a new language in childhood master it more quickly and thoroughly than do people who learn a language in adulthood. Language and Nonhuman PrimatesSome researchers have tried to teach apes to use language. Because of the structure of their vocal organs, apes can’t say words, but they can communicate using signs or computers. Using these means, a pes can make requests, respond to questions, and follow instructions. The Case of Washoe the Chimpanzee Researchers at Central Washington University taught a chimpanzee named Washoe to use American Sign Language (ASL) to communicate. She could sign not only single words but also meaningful combinations of words. She could follow instructions and respond to questions given in ASL.Later, Washoe’s foster child, Loulis, learned signs just by watching Washoe and other chimps that had been trained to use language. Some research even suggested that language-trained chimps may use signs spontaneously to communicate with each other or to talk to themselves, although this behavior is not thoroughly documented. Skepticism about Ape Language Critics of the idea that apes can learn and use language have maintained several arguments: Apes, unlike people, can be trained to learn only a limited number of words and only with difficulty.Apes use signs or computers to get a reward, in the same way that other animals can be taught tricks. But learning tricks is not equivalent to learning language. Apes don’t use syntax. For example, they don’t recognize the difference between Me eat apple and Apple eat me. Trainers may be reading meanings into signs apes make and unintentionally providing cues that help them to respond correctly to questions. Clearly, communication in nonhuman animals differs drastically from language in humans. The spontaneity, uniqueness, and reflective content of human language remains unmatched. Nonprimates Can CommunicateResearchers have taught nonprimate animals, such as parrots, to communicate meaningfully. Parrots that participated in language acquisition studies learned to identify dozens of objects, distinguish colors, and make simple requests in English. One famous example is Alex the African gray parrot, owned by Irene Pepperberg from the University of Arizona. Alex can â€Å"speak† hundreds of words, but what makes him mor e unique is that he appears to do more than just vocalize. Though Pepperberg does not claim that Alex uses â€Å"language,† she does believe that when Alex talks, he is expressing his thoughts, not just mimicking.The Structure of Cognition Cognition, or thinking, involves mental activities such as understanding, problem solving, and decision making. Cognition also makes creativity possible. The Building Blocks of Cognition When humans think, they manipulate mental representations of objects, actions, events, and ideas. Humans commonly use mental representations such as concepts, prototypes, and cognitive schemas. Concepts A concept is a mental category that groups similar objects, events, qualities, or actions. Concepts summarize information, enabling humans to think quickly.Example: The concept â€Å"fish† includes specific creatures, such as an eel, a goldfish, a shark, and a flying fish. Prototypes A prototype is a typical example of a concept. Humans use prototypes to decide whether a particular instance of something belongs to a concept. Example: Goldfish and eels are both fish, but most people will agree that a goldfish is a fish more quickly than they will agree that an eel is a fish. A goldfish fits the â€Å"fish† prototype better than an eel does. Cognitive Schemas Cognitive schemas are mental models of different aspects of the world. They contain knowledge, beliefs, assumptions, associations, and expectations.Example: People may have a schema about New York that includes information they’ve learned about New York in school, their memories of New York, things people have told them about New York, information from movies and books about New York, what they assume to be true about New York, and so on. Theories of Cognitive Development Cognitive development refers to the change in children’s patterns of thinking as they grow older. Jean Piaget’s Stage Theory The scientist best known for research on cognitive dev elopment is Jean Piaget (see pages 72–75), who proposed that children’s thinking goes through a set eries of four major stages. Piaget believed that children’s cognitive skills unfold naturally as they mature and explore their environment. Lev Vygotsky’s Theory of Sociocultural Influences Psychologist Lev Vygotsky believed that children’s sociocultural environment plays an important role in how they develop cognitively. In Vygotsky’s view, the acquisition of language is a crucial part of cognitive development. After children acquire language, they don’t just go through a set series of stages. Rather, their cognitive development depends on interactions with adults, cultural norms, and their environmental circumstances.Private Speech Vygotsky pointed out that children use language to control their own behavior. After children acquire language skills and learn the rules of their culture, they start to engage in private speech. They first talk to themselves out loud, and then, as they grow older, silently, giving themselves instructions about how to behave. Current Research on Cognitive Development Current research indicates that children have complex cognitive abilities at much younger ages than Piaget suggested. As early as four months of age, infants appear to understand basic laws of physics.For example, a four-month-old infant can recognize that solid objects cannot pass through other solid objects and that objects roll down slopes instead of rolling up. At five months of age, infants can recognize the correct answers to addition and subtraction problems involving small numbers. These observations have led some researchers to speculate that humans are born with some basic cognitive abilities. Critics argue that researchers who find these results are overinterpreting the behavior of the infants they study. Quick Review The Structure of LanguageLanguage is a system of symbols and rules used for meaningful communi cation. A language uses symbols and syntax and is meaningful and generative. Language is organized hierarchically from phonemes to morphemes to phrases and sentences. Children develop language in a set sequence of stages. Theories of Language Acquisition Behaviorist B. F. Skinner strongly supported the idea that language depends largely on environment. Skinner believed that people acquire language through principles of conditioning. Critics argue the inadequacy of behaviorist explanations.Some cognitive neuroscientists have created neural networks that can acquire some aspects of language by encountering many examples of language. They think children may acquire language in the same way. Noam Chomsky is the main proponent of the importance of biological influences on language development. Chomsky proposed that human brains have a language acquisition device that allows children to acquire language easily. Some researchers believe that language is both biologically and environmentall y determined. The linguistic relativity hypothesis states that language determines the way people think.Today, researchers believe language influences, rather than determines, thought. Two ways that people use language to influence thinking are semantic slanting and name calling. People master a new language better if they begin learning it in childhood. Nonhuman animals can learn some aspects of language. Language and Nonhuman Primates Some researchers have tried to teach apes to use language. Apes can communicate, but researchers are divided on whether this communication can really be considered â€Å"learning language. † The Structure of CognitionCognition involves activities such as understanding, problem solving, decision making, and being creative. People use mental representations such as concepts, prototypes, and cognitive schemas when they think. Theories of Cognitive Development Jean Piaget believed that children’s cognitive skills unfold naturally as they ma ture and explore their environment. Lev Vygotsky believed that children’s sociocultural environment plays an important role in cognitive development. Some researchers have shown that humans are born with some basic cognitive abilities. Problem-SolvingProblem-solving is the active effort people make to achieve a goal that is not easily attained. Three common types of problems involve inducing structure, arranging, and transformation. Some approaches to problem-solving are trial and error, deductive and inductive reasoning, use of algorithms and heuristics, dialectical reasoning, creation of subgoals, use of similar problems, and changes in the way the problems are represented. Researchers have identified many obstacles to effective problem-solving, such as focus on irrelevant information, functional fixedness, mental set, and assumptions about unnecessary constraints.Decision-Making Decision-making involves weighing alternatives and choosing among them. Additive strategies and elimination strategies are ways of making decisions about preferences. Using expected value, subjective utility, the availability heuristic, and the representativeness heuristic are all ways of making risky decisions. Using the representativeness heuristic can make people susceptible to biases, such as the tendency to ignore base rates and the gambler’s fallacy. Using the availability heuristic can make people susceptible to overestimating the improbable or underestimating the probable.In an effort to minimize risk, people also make decision-making errors, such as the overconfidence effect, the confirmation bias, and belief perseverance. Creativity Creativity is the ability to generate novel, useful ideas. Creativity is characterized by divergent, rather than convergent, thinking. Some characteristics of creative people are expertise, nonconformity, curiosity, persistence, and intrinsic motivation. People can best realize their creative potential if they are in environmental circumstances that promote creativity.

Organic & Processed foods: What’s Better Essay

There are a lot of differences and similarities with organic and processed foods. I’m sure when everyone was a kid they could eat whatever they wanted and didn’t worry about what it did to their body. I remember when I was younger I would cook a whole Tostito’s Pizza and consume the whole thing myself in under five minutes. I wouldn’t gain a pound and that same night I would have two big macs (back when there was a big mac Monday) and sit on my butt playing video games. It’s not like I didn’t have the exercise. I played all sorts of little league sports including baseball and soccer. You may think I was writing an essay on the effects of metabolism but I’m more interested in finding out what the words â€Å"Organic† and â€Å"Processed† foods really mean. What kind of chemicals are in them and what the huge fuss is about. I think this is an important topic to write about because most people don’t know what the difference is. What makes a food organic? What happens to the ingredients when converting it into a processed food? I think if you understand more about this issue people would choose to live healthier and know how easy it is to alter their diet. Organic food has gone back in history ever since the first person decided to take and seed, plant it, and then eat what the plant produced. This is known as farming if you were confused. Over the years farming has evolved from types of fertilizer used, machinery, tools, equipment and even animals. Machines can harvest a field of crops in one hour where a hundred years ago it would have taken a full day. Processed foods are more close to our time. In the 1920s, women were growing weary of preparing foods from scratch, and ready-to-cook foods were becoming more available. World War I brought about new methods of food processing, including canned and frozen foods. When World War II hit by the 1940s people needed away to ration the food for the soldiers. After the war, many new â€Å"convenience foods† were introduced like dehydrated juice, instant coffee, and cake mix. Farmers used fertilization and irrigation to increase crop yields, decreasing the vitamins and minerals in those plants. Government subsidies for corn and soy led to a food industry with a financial incentive to use high fructose corn syrup, hydrogenated oils, modified corn starches to produce lots of highly processed (and unhealthy) foods. The U. S. issued guidelines for adding iron, vitamin B, thiamine and riboflavin to bread and other grain products to offset nutrient deficiencies. With all of the changes that were going on in the food industry there was always someone trying to tighten the noose by the power of democracy. Soon farmers were being replaced by machines and factories. Fast food corporations were growing more and more and farms were depleting less every day. As I researched into the major debating controversy I found that most people would agree that the organic foods are healthier to consume. The organic industry has sky rocketed in the last couple years because of the messages that was sent out saying organic farming is safer and healthier for the environment. But is it actually healthier for you in the long run? Other consumers argue that organic farming can be dangerous and unsafe to digest due to the invisible toxins and pesticide found in organic produce could even be as dangerous as synthetic chemicals. Most people would agree that switching from a processed food nation to an organic food country would be best. But it’s easier said than done. Organic foods and processed foods are different in a lot of ways. Processed foods contain more bad chemicals and bad fat per calorie than any other natural food. You can determine whether a food is processed by looking at the ingredient list. The longer the ingredient list, the more processed a food is likely to be. Processed foods are usually found in the center aisles of the grocery store and are more likely to contain ingredients that you are not able to recognize. Organic foods are foods that don’t have any harmful fertilizers, pesticides or sewage. Animals that produce meats, poultry, or eggs and don’t use any kind of steroids in the process are considered organic. There are a lot of different sides to both of these categories. Most critics who agree with organic foods are humanitarians who believe in renewable resources and not using exotic chemicals that may be harmful to the environment. Also in this case it helps with how the animals are being treated. For example, in a processed factory for animals the cows are caged in tight corners and forced to eat so they are worth more. When animals are raised by farmers, they have the freedom of a decent sized field and their manure will decompose and fertile the land. On the other hand processed food critics have done research that shows processed food saves on money and meets the demand of the growing population of consumers. The only way to meet this demand is by using steroids and food enhancers/substitutes. People buy processed foods because they have a longer expiration date and you can freeze them. It takes time to prepare a meal from organic foods. Processed foods can be made easily by adding water, boiling, frying or if you’re an American like me, microwaving. Plus processed foods are typically cheaper, you get more bang for your buck. What is organic food? The term â€Å"organic† refers to the way agricultural products are grown and processed. Specific requirements must be met and maintained in order for products to be labeled as â€Å"organic†. Organic crops must be grown in safe soil, have no modifications, and must remain separate from conventional products. Farmers are not allowed to use synthetic pesticides, bioengineered genes (GMOs), petroleum-based fertilizers, and sewage sludge-based fertilizers. Some organic foods contain more vitamins than processed foods, according to Organic Facts. For example, organic milk contains more vitamins than non-organic milk. Organic milk is believed to be of better quality because the cows that produce it eat a better diet, which includes grazing for large parts of the day. Organic fruits and vegetables also tend to contain more vitamins than processed ones, according to nutritionist Shane Heaton. Not only do many organic foods contain more vitamins than processed foods, they also contain more antioxidants, according to Organic Facts. A University of California Davis study found that organically-raised tomatoes had higher concentrations of the antioxidants quercetin and kaempferol, both of which may protect the body against certain diseases by helping promote cell health. The researchers at the University of California Davis believe that organic foods contain more antioxidants because plants create antioxidants in order to defend themselves from plant-eating insects. Conventionally raised plants do not need to produce as many antioxidants because any plant-eating insects that might prey on them are controlled with insecticide. Because organic foods must be raised and processed without insecticides, herbicides or similar chemicals, the finished product available in the store usually contains fewer of these chemicals than processed foods, according to Heaton. Although many pesticide residues may be harmless to humans, people who are sensitive to others may experience symptoms that can be alleviated by reducing the amount of conventionally processed food in the diet. Farmers also use a cycling method when farming so they can reduce the amount of bugs and pesticides. They will plant different crops in each cycle so that they do not get the same pesticides returning. Organic farming is designed to protect the environment. By removing chemicals and other artificial farming methods from the equation, you save soil and water and reduce pollution. Organic farmers also use more humane methods of producing their meat, eggs and other animal products. For those concerned with the environment or the treatment of the animals they eat, the peace of mind is worth the extra cost. With all of the good that comes from organic food what could possibly be some negative things about eating organic foods and why does everyone think that processed foods are so bad? Because organic farmers do not use artificial means to produce their products, they tend to produce less. Organic farming is also more expensive than conventional farming, as can be seen with the cost of using a chemical weed killer versus the manpower required to manually pull weeds and rotate crops, for example. The combination of lower production rates with higher overhead makes organic products more expensive. One can also argue on the fact that it may be more environmentally friendly if you drive the shorter distance such as 50 miles to your local farmer to purchase food rather purchasing the organic food that has traveled over 1500 miles to get to you. Organic food can sometimes be limited to people, especially if you live in more rural areas. The most important issue that seems to affect all of America is the simple fact that because organic food is harder to process and is more time consuming to grow there is a shortage of it. Organic food does not come in huge quantities like other food does. So because of organic food being in high demand from grocery stores and other consumers the prices are extremely high. That then means there are a high percentage of people in our society that cannot afford to eat organic food, to me that is just reminding someone that they are basically â€Å"poor†. So what if they want to eat healthy as well? We are just going to say sorry you are out of luck because you can’t afford it? Next let’s talk about processed food. What is processed food? Processed foods have been altered from their natural state, either for safety reasons or for convenience. The methods used include canning, freezing, refrigeration, dehydration and aseptic processing. Processed foods are very convenient for the society because they can usually be prepared very quickly and allow minimal time and energy. By processing food we can also preserve food so that it will have longer shelf life, allow us to lower prices, and get food to more rural areas. When we process food we are putting preservatives into them so that they will last longer which allows stores and consumers to sell them longer without them spoiling. By allowing the foods to not spoil as quickly as others the stores can lower the prices which allows everyone of all social classes to be able to buy the foods. Another huge reason that processed foods is very ideal for our society is the fact that we are able to get the food to more rural areas. When we transfer organic foods to rural areas it ends up costing more because to get it there before the food would spoil would cost an extreme amount of money which then makes the prices of food go up. By being able to preserve the food so that its expiration date is longer we can get the food to rural areas in more effective ways that allows the environment to be safer and cleaner, then also reducing the prices in which more people can afford the food. We tend to think of processed food as bad, like most high-fat, high-calorie snack foods or even those prepackaged meals you fix in a skillet, but it turns out that some of these foods are not bad for your health at all. For example, milk would be considered a processed food because it’s pasteurized to kill bacteria and homogenized to keep fats from separating. Some people prefer raw milk, but it can lead to lead to food-borne illness, so most of us are happy to consume the healthy processed milk we find in our grocery stores. Freezing vegetables preserves most vitamins and minerals and makes them convenient to store, cook and eat all year around. Fruit and vegetable juice is also an example of a healthy processed food — usually. In fact, some orange juice is fortified with calcium to make it even more nutritious. Oatmeal, unbreaded frozen fish fillets, canned salmon, frozen berries and 100-percent whole grain bread are also examples of processed foods that are good for you. Sure, there are a lot of processed foods that aren’t good for you. Many of these bad ones are made with trans-fats, saturated fats, and large amounts of sodium and sugar. These processed foods should be avoided, or at least eaten sparingly. Processed foods are also more appealing to the eye and because of food additives they can taste even better. Basically the biggest downside to processed foods is one will lose a few nutrients. After researching these two topics I understood what the communal agreement was and the controversy that surrounded it. But I needed to find out what else needed to be further questioned. There wasn’t a lot of information surrounding what affects it would have on the grocery stores. The prices that were listed on a trusted source showed that the organic food was often priced higher than any processed food items, usually forty to fifty percent more. This is because it takes a lot of steps to grow and distribute organic foods, here are some of the steps it takes to successfully distribute the produce. Prepare the field and properly fertile the land after the previous plants have been harvested, this process is what takes most of majority. They have to buy the seed themselves and base off what they want to sale the crop for to turn around for some profit. They also have to put in the man hours and distribution cost. As you can see it takes a lot of time to complete this process rather growing and distributing it all in one location like how the processed food organizations do it. As I was saying I would like to see what the total cost was on organic food verses processed food, maybe from a big corporation like Wal-Mart to compare the differences. One other thing that I think should be a little more covered is the shelf life on an organic and non-organic food item. Because non-organic food has preservatives in them they can last a lot longer. In this case you would have to make less trips to the store and save money on gas, it will also help with the environment. But would it be worth it in the end. Organic foods can go bad very quickly but it needs to be broken down to a science. How much longer will a processed mango last than organic mango. After the experiment has concluded customers will have more knowledge of what to buy accordingly. Between organic and processed foods organic foods may have more natural nutrients when eaten. But you can get just as good nutrients from processed foods. It really boils down to what one chooses to eat and what they prefer. There are alternative ways to getting all nutrients one needs for their body without having to pay a high price if you can’t afford it. Even if you eat organic foods that doesn’t mean someone will not indulge on the fatty foods such as ice cream, potato chips, etc. It comes down to what one will eat whether it is processed or organic.

Hand Foot and Mouth Disease Essay Example

Hand Foot and Mouth Disease Essay Example Hand Foot and Mouth Disease Essay Hand Foot and Mouth Disease Essay 1. Introduction This report discusses what Hand, Foot and Mouth Disease (HFMD) is, how it is spread as well as the precautions one should take to avoid getting HFMD. There have been recurrent outbreaks of HFMD over the last few years and similar outbreaks of HFMD have also occurred in the region, namely in Brunei and Sarawak. In the recent outbreak in March this year, the number of HMFD cases in Singapore reached a peak of 785 cases a week. With the recurrent outbreaks of HFMD in Singapore and the region, and the potentially serious effects of the disease, particularly on children, the Ministry of Health (MOH) has tightened its guidelines on the procedures for the management of HFMD in child care centres in Singapore. In fact, HFMD is one of 30 ‘notifiable’ diseases, which means that general physicians, polyclinics and hospitals have to inform MOH about every case of HFMD. Owing to the major impact HFMD has on public health, this report serves to highlight several important aspects of HFMD and is submitted to Dr Mark Lim, lecturer of Public Health (PH) at Dover Polytechnic, in partial fulfilment of the PH module. 2. What HFMD is 3. 1. Definition HFMD is defined as Hand, Foot, and Mouth Disease. It is caused by intestinal viruses, with Coxsackie virus and Enterovirus-71 being the most common. Out of the 80 different strains of HFMD, enterovirus-71 is the most infective. 3. 2. Victims HFMD affects both children and adults although it is most commonly found to infect children under the age of 10 years old. : Anyone is at risk of being infected with the HFMD virus but not everyone who is infected becomes ill. Unlike adults, infants, children and adolescents have fewer antibodies that cause them to be immune from exposure. This causes them to be more prone to infection and illness from the HFMD virus. 3. 3. Symptoms After infection, symptoms begin to show around the 3rd-7th day. This is known as the ‘incubation period’. Fever is often the first symptom of HFMD. Other symptoms include sore throat, rash or blisters (on hands, soles of the feet, or buttocks), mouth ulcers, poor appetite, vomiting, diarrhoea and fatigue. 3. 4. Impact Enterovirus-71 killed several children during the Singapore outbreak in 2000, along with an average of 1,140 cases reported each week (Lee, 2005). Consequently, nurseries, kindergartens, enrichment centers and play areas in fast-food restaurants or shopping centers were closed for two weeks to prevent the disease from spreading further. In 2006, there were usually 220 cases of HFMD a month throughout the year. 3. How it is spread The HFMD virus is transmitted from person to person through physical contact with the nasal discharge, saliva, faeces and fluid from the rash of an infected person. It can also be transmitted indirectly from contaminated items such as utensils and toothbrushes. An infected individual is more contagious during the incubation period or the first week of infection. Chances of transmission of this enterovirus are increased by poor hygiene and also overcrowded living conditions. This is why it is advised for children who display any symptom of the infection to avoid visiting public areas and remain within their own homes after consulting medical check-up. 4. Treatment and Prevention There is neither specific treatment to cure HFMD nor is there vaccine to prevent it. However, there is treatment to relieve the symptoms of the illness known as symptomatic treatment. Since the disease is mild and self-limiting, most patients will recover in 7 to 10 days but it may lead to rare complications such as inflammation of the brain and heart. The risk of infection can be lowered by practicing good hygiene. This includes washing hands with soap under running water frequently and disinfecting them afterwards with chlorine-containing bleach. In addition, avoiding close contact such as kissing and hugging with an infected person is another precaution. Furthermore, areas or items handled by the infected individual or are contaminated by his nasal or oral secretions should be cleaned and disinfected thoroughly with sodium 0. 5% hypochlorite solution, an active ingredient in many household types of bleach. In fact, the MOH has implemented a measure where childcare centres and kindergartens with more than 16 HFMD cases or an attack rate greater than 23%, and a transmission period of more than 24 days will be closed for 10 days in attempt to stop the transmission chain. (Ministry of Health, 2013) 5. Conclusion In conclusion, HFMD impacted Singapore greatly. Although it may be self-limiting, it is a highly contagious disease that is capable of causing critical illness and eventually death. Up till today, HFMD cases are continuously being reported to MOH. This epidemic is a global situation alongside bird-flu, H1N1 and other types of deadly contagious diseases. From this report, it is understood that prevention is much more effective than treatment since there is no fixed cure for HFMD. This report also clearly states that it is a team effort by all Singaporeans to counter such a crisis, not just the government’s responsibility but the citizens’ individual responsibility as well. 6.

Free Essays on Sir Issac Newton

Newton, Isaac (1642-1727)Newton, Isaac (1642-1727) Isaac Newton was born in Woolsthorpe, Lincolnshire, a premature infant not expected to live. His father (of the same name) had died just three months before. His mother, Hannah Ayscough Newton, remarried when he was three, and left him with his grandmother until her second husband died, in 1653, when Newton was 11. He was educated at King's School, Grantham, and it was assumed he would continue in the farming tradition of his family, but finally his mother became convinced that he should be prepared for entry to university, and in 1661 he went up to Trinity College, Cambridge, as a poor scholar who would have to earn his keep by doing menial tasks for the Fellows. Newton showed no particular promise in his early years at Cambridge, but Isaac Barrow, who held the Lucasian chair of mathematics, gave him much encouragement. Newton took his degree without distinction (in 1665), and would have prepared for his MA, but in 1664 the Great Plague broke out in London, and the university was closed down the following year. At home during the plague years, he studied the nature of light and the construction of telescopes. By a variety of experiments upon sunlight refracted through a prism, he concluded that rays of light which differ in color differ also in refrangibility - a discovery which suggested that the indistinctness of the image formed by the object-glass of telescopes was due to the different-colored rays of light being brought to a focus at different distances. He concluded (rightly for an object-glass consisting of a single lens) that it was impossible to produce a distinct image, and was thus led to the construction of reflecting telescopes, perfected by William Herschel and the Earl of Rosse. At the same time, he was working out his ideas on planetary motion. On his return to Cambridge (1667), Newton became a Fellow of Trinity College, and, in 1668, took his MA. In the fo...

Buffer, acid and base Research Paper Example | Topics and Well Written Essays - 1000 words

Buffer, acid and base - Research Paper Example A strong battery acid has less than one pH while a strong base has such as drain cleaner has about 14 pH (Lynnette, 2009). On the other side pOH is a measure of the concentration of hydroxide ions, alkalinity or OH-. It measures the basicity of a solution according to the dictionary of Chemistry. pOH is not measured independently rather it is derived from pH. The difference between the two can be described as pH means the H+ ion concentration which indicates the acidic nature of compound while pOH means the concentration of OH- ion which indicates the basic nature of the compound. The following equation will help us to know about both pH and pOH that how they make a 14 point scale for measuring the alkalinity/basicity or acidity of a substance. In the human body, all fluids are aqueous. It is a solvent that is only present in water. That means all body fluids have pH value either narrow or wide range. Scientific researches claim that the pH range of blood should be slightly basic i.e. from 7.35-7.45. If the range sees drastic change, it is very likely to cause illness or death as so much acidity and basicity is injurious for health. The Arrhenius definition for acids states that acids produce hydrogen ions in aqueous solutions or when they are added to water. Acids release Hydrogen ion (H+). An acid reacts with magnesium, zinc or aluminum and forms hydrogen (H2(g)). It also reacts with such compounds that contain CO32-Â  and carbon dioxide and water is produced. Acids can corrode metals, eat them away to weaken. Acids are so powerful that they can conduct electricity. They are found in car batteries that are so powerful to run the car. An acid turns the litmus paper into red. It is sour in nature and found in many natural fruits and vegetables e.g. lemons have citric acid. In a laboratory, it is very dangerous to taste acid. In kitchens, we find vinegar, a type of acid. It is acetic acid that gives vinegar a sour taste (Lynnette,

Research Paper Example It was an all high for female in both public and private nonprofit institutions. The reverse was witnessed in the private for profit institutions, with males being more than females at forty-eight percent and thirty-six percent respectively. Every start of an academic year comes with an ever-increasing price of college education. An interview conducted on persons of ages eighteen to sixty-five, found out that sixty-five percent of the respondents believed that college prices were growing at a faster rate than other items and services. Eighty three percent went on to explain that students borrow too much to go to school. The school year 2013-2014, recorded an average tuition and fees for undergraduate at public four-year colleges at $8,893 a two point nine rise from the previous year. The private non-profit four-year colleges recorded an average tuition fee of $30,094, which was a three-point eight percent from the previous year. For over the last decade, an increase in tuition and fees has been on a rise. At the four-year public colleges the raise has hit a fifty-one percent rise. The private non-profit four-year colleges, the raise was at twenty-five percent. This raise has resulted to an increased number of students in need of financial assistance. The last decade has witnessed the number of Pell grants rise from four points eight to eight point eight million. The retention of University student is of importance more so to the college administrators in trying to improve the graduate rates and decreasing of tuition and fees since the economy is known to have a noticeable effect on the retention
