1. Discuss the significance of Valley Forge Essay
1. Discuss the significance of Valley Forge - Essay Example Conditions in the Valley Forge were poor and inhumane. Many men suffered hunger, cold, and diseases, and eventually many of them died2. Amid the underlying challenges in the valley, the troops, under the command of General Washington, stayed committed to their goal. It is this persistence and resilience that would eventually make the American Revolution a dream-come-true. The course of liberty remained true and alive in their hearts. The continental army’s immense suffering in the Valley Forge kept them expectant that things would get better. Against all odds, Valley Forge provided the troops with an opportunity to train, reorganize, and get ready to face the British. The army had eventually secured help and support that allowed it to embark to the revolutionary pursuit. In this respect, Valley Forge was a defining factor of the course that American Revolution would take after June, 1778. Essentially, Valley Forge had taught the troops that what awaited them was not a walk in the park. In conclusion, the success of the American Revolution was partially attributed to Valley Forge. Even though troops had suffered and died in the valley, the dream of a liberal America remained alive. North American break off the British Empire received a vital boost from the mature army that emerged from Valley Forge. Suffering, sacrifice, freedom, and liberty characterized the Valley Forge troop activity in the light of the American

Chagas Disease Essay Example | Topics and Well Written Essays - 1000 words
Chagas Disease - Essay Example More commonly, it is referred to as paleoparasitology (Ferreira et al., 2000). The discovery of the presumed parasite in the human remains is then extrapolated to the present relationship between the host and the parasite Chagas disease or American trypanosomiasis is caused by Trypanosoma cruzi. The reservoir exists in wild amongst various animal species constituting the sylvatic cycle (Afuderheide et al., 2004). The vector for its transmission is reduviid bug (family Reduviidae, subfamily Triatominae). These insects hide in the crevices, nests or human dwellings in case of domestic cycle and emerge at night to feed upon the blood of their prey (Afuderheide et al., 2004). The infection is caused by rubbing of the bitten area where the parasite deposits the faecal matter (Afuderheide et al., 2004). This leads to entry of the parasite into the blood stream from the breached skin or conjunctiva. Parasitemia may lead to acute manifestations of myocarditis or meningoencephalitis that have a mortality rate of 10% (Afuderheide et al., 2004). The disease may progress to a chronic stage characterised by flare up of febrile episodes and progressive damage to myocardium or gut leading to dilated cardiomyopathy or segmental paralysis of parts of gastrointestinal system respectively (Afuderheide et al., 2004). Researchers to study the archaeological remains for the evide... These findings were supplemented by discovery of dwellings made of mud bricks, which is a common habitat of these bugs.Molecular studies included immunochemical methods and electron microscopy. Histological sections have also demonstrated the parasite even in desiccated mice tissue (Bastos et al. 1996). However, the most vital tool that has enabled the authors to draw important inferences regarding the evolution and epidemiology of Chagas disease is the extraction and amplification of DNA segments of T. cruzi from mummified tissues.Origin of samples: Atacama Desert with its dry hot winds and arid climate has been a source of mummified tissues for many researchers (Ferreira et al., 2000; Afuderheide et al., 2004; Guhl et al., 2000). This type of climate favours the preservation of body tissues in a dehydrated form and nearly arrests its decomposition. Moreover, this geographical region coincides with the distribution of the disease, along coastal region of South America in Peru and Chile. South American natives buried their dead in shallow sandy soils that led to preservation of tissues in a desiccated mummified form Laboratory techniques: This desiccated tissue is rehydrated and pulverised and DNA is extracted. The extracted DNA is then amplified using the Polymerase chain reaction. The amplified DNA participates in the hybridization process with standardised primers and probes under controlled conditions. Hybridisation of the DNA extracted from the mummified tissue samples with the probe nucleotides constitutes a positive test result. Hybridisation can be identified by gel electrophoresis and analysis of bands by radioisotope techniques. Authentication and sources of error Concern has been raised

Euphoria Case Study Essay Example for Free
Euphoria Case Study Essay Human life as we know has been proven better with a scientific discovery created through the efforts of Pseudoscience Research Inc. (PRI), a conglomerate pharmaceutical corporation responsible for other life-changing advances in modern biological science and technology today. This new discovery is guaranteed to improve the quality of life for most people and would eventually establish a harmonious society human beings aspire for since time immemorial.            In a lavish ceremony held at the offices of PRI, the miracle drug was unveiled to wide public acclaim. It was described as one of the most innovative and promising invention of the 22nd century. The drug Euphoria is generally regarded as the most effective and best-selling drug since viagra hit the stores. Euphoria comes from the Greek word euphoros meaning healthy. As what its name espouses, Euphoria aims to improve the lives of the majority of people who live life in constant depression, poverty, and hunger by inducing natural happiness and elation. Indeed, Euphoria changes everything.            As a response to the growing demand in society, PRI started to conduct research on a drug that may well be the biological ubermensch of the masses in order to rid of constant financial, social, and personal problems that the individual has to experience on a daily basis. On July 14, 1971, PRI jumpstarted the research on a new medicine that will biologically eliminate problems and hardships of an individual by developing a pill concentrated with endorphins and other happiness-inducing chemicals that will harmlessly alter the genetic code of the person as well as increase the normal endorphin count of the normal human body. Thus, Euphoria was born. Since the drugs invention, it has been tested on human subjects to adhere to the pre-existing laws on animal welfare in lieu with testing. During the early 90s, PRI was threatened with bankruptcy as the company was openly criticized for making an amoral and immoral drug simultaneously. Mostly pro-life groups rejected the idea of the drug, as it did not value human life while intellectuals criticized it as something that is atrocious since it takes out choice of a person to be miserable. But it was a famous Hollywood actress who supported the drug and brought PRI into the A-list of corporations in the world today. The three-time Oscar winner actress argued publicly that the drug has helped her made her career and improved her way of life ever since. Consequently, PRI sales on Euphoria went up by 50% in just a year and soon the company made a name for itself as one of the leading brands in healthcare in 2004. Today, Euphoria has replaced painkillers, anti-depressants, and other small-time antibiotics since it completely prevents the user from getting sick. It has been proven effective with absolutely no side effects such as drowsiness, dizziness, stomach pains, chest pains, headaches, fever, and death. Since its invention, the drug has been widely-used by the public and from substantial surveys conducted by PRI itself, it has been revealed that almost 95.457% of the population take the drug as an answer to the problems since there are no other drugs that will enable them to be happy and successful. In addition, that percentage also proves the drugs popularity and effectiveness, as it won numerous awards including the Discovery of the Year recognition from Time Magazine. In 2008, the drug established the name of PRI, becoming the worlds foremost conglomerate in medicinal development. Humble Beginnings            The credit with the creation of the phenomenal drug goes to Dr. William Falsetto, a Harvard medicine graduate, who got the sudden inspiration of creating Euphoria during a friendly banter over a couple of beers when his colleague suggested him to create a drug that has a natural high without the side effects rival to that of viagra and morphine. Because of his background as a distinguished alumnus of one of the top universities in the world, his credibility follows with his invention and therefore the drugs eventual success. [1]            He based his assumptions from an empirical laboratory experiment wherein he carefully tested the number of endorphins that the human body produces at a normal rate. After determining such, he further experimented on the subject with three substantive theories. First is to determine the amount of endorphins that a normal body produces when exercising. In a result published in the PRI research journal from 1991, Falsetto concluded that the body gives off 86% more endorphins that stimulate happiness and elation.[2] However, he debunked his theory stating that exercising is not an activity done by majority of the masses and would therefore cause a low selling and marketing rate. The second theory was to determine the amount of endorphins when eating large amounts of chocolate. The result was also promising but Falsetto soon discovered that chocolate-induced happiness is followed by undesirable side-effects such as diabetes and fluctuating sugar levels of the body. The last theory proved to be the most effective as Falsetto discovered that endorphins could be extracted as a solid powder form and could be placed in regular tablets sold. The formula is of course under strict protection of the PRI, NSA, CIA, FBI, EUROPOL and the United Nations, but Falsetto disclosed in a press interview when the drug reached its 10th year of success that it contains naturally-produced endorphins that add to the natural threshold of the human body and it increases happiness that in turn causes motivation, energy, and a positivist attitude. He boldly added that the drug can replace viagra since it also increases the sexual drive of the human body. Because of his background as a Harvard graduate, the credibility of the drug was never compromised when it went on sale since 1995.[3]            In relation with the drugs almost monumental failure, the Hollywood actress who still refuses to reveal her identity said that it almost saved her life and career. Since then, PRI inaugurated the celebrated actress as one of the chairpersons of the company and eventually her ascension as the CEO of the company. Her statement reached almost the entirety of Hollywoods royalty and soon, millions of people were convinced of Euphoria. Heads of State and royal families soon followed suit, stating the drugs effectivity and rationality over decision-making, political relationships, and terrorist negotiations. The drug also replaced the harmful and illegal drugs such as cocaine and marijuana since Euphoria induced a natural high without the hallucinogens found in the illegal drugs.            In 2001, 92% of the world population agreed on the use of Euphoria and consequently stamped out the drugs immoral and unethical issues regarding its use and nature. The test subjects widely accepted the drug[4] since the drug contains natural endorphins, and it follows that it marginally increases elation and happiness feeling for the person. Since happiness and elation are important for personal motivation, the drug then helps in changing the mood of the person as well as affecting change with regards to eating habits and behavior. Also, work production has also been increased since employees are now very happy with their work. Euphoria also replaces viagra as a safe alternative since the drug is naturally produced. With health issues, endorphins also increase the white blood count of the body and therefore prevent the body from acquiring diseases.[5] Majority of the people agree on the drug since it is right for the body and life as well as the right thing to do. Its moral issues were disproved since there are no deaths or accidents that are linked to the drug.[6]            In 1992, there was a worldwide appeal to governments that the standard of living for most of the countries is declining because of unemployment and poverty. However, as soon as Euphoria was introduced to the world, many agree that the drug has saved many lives. It is noteworthy to mention that in one of the political debates in the UN meeting of 2007, the assembly concluded that the quality of life is steadily declining and if the case is not addressed, more human lives are at stake. Either the drug should be globally legalized or the world would continue to degrade in terms of living standards and health issues. Naturally, the drug was finally given worldwide approval during September of that year, and since then, it has been proven effective.[7] However, several pharmaceutical companies rejected the claim of Euphoria to be a universal solution for biological problems. The case went to court, but it was easily dismissed by the ruling that there were no substantive claims to prove that the drug was indeed ineffective. Consequently, it also proved to be the turning point for major and minor drug companies as PRI bought the companies and formed into a multi-national biological research company.[8] Furthermore, since there are contentions with regards the effects of the medicine, it has concluded that the medicines claims are true. Mr. Falsetto received the Nobel Peace prize for Medicine and named one of the 22nd centurys greatest thinkers.[9]            Because of Euphorias discovery and monumental success, it has been regarded as the drug that saved the world from misery and caused much development in the quality of living for the whole world. There are no more wars, political maneuvering, strife, poverty, and colds. The global quality of life has improved, notable through the many recent milestones in human history such as excessive singing, the development of the cure against AIDS and HIV, and a harmonious societal structure where there is no class struggle and alienation since everybody is equally happy. Thanks to Dr. Willam Falsetoo, the world is now a better place.[10] [1]   Ad Hominem (Argument to the Man) [2]   Error of Fact [3]   Weak Analogy [4]   Ad Populum (Appeal to the Masses) [5]   Hasty Generalization [6]   Equivocation [7]   False Dichotomy [8]   Appeal to Ignorance [9]   Burden of Proof [10] Post Hoc (False Cause)

Observation studying on an autistic child
Observation studying on an autistic child Nowadays, Autism is a very popular topic to discuss. Some biological experts said that genetics can cause autistic problem. Aspergers syndrome is one of them. People who have this syndrome may have normal or highly intelligent compare with other people. This syndrome is difficult to analysis because their intelligent can replace the autistic personality. The objective whose name is Z.H was born in 2004 in a Chinese family; later his parents realized his was not able to verbal. After medical checkup, doctor said Z.H has autism. I appreciate that I have an opportunity to have an interview with a six-year-old boy who has this syndrome. This is an individual assignment due to Z.Hs body and mental condition. For these years, Z.H has been to many developmental therapies and special education to learn some certain manners. The therapies are broken down into several parts; most of them are activities to establish a childs connection between mind and body. My studying is going to break down i nto three main groups. Detail in my proposal: Interview this person and his parents to know his background. Observational Study in this childs behavior. His concentration. Introduction in Autistic problems and theory For over a century, experts argue what causes Autistic problem whether it cause by nature or nurture. If we say it is completely cause by nature, it will relate with neurology and genetic make-up. In recent studying, if family members who have this syndrome, the chance he or her siblings would have this disease approximately 10 to 20 percent. During the world war two, Hans Asperger discovered syndromes which similar with autism, but participants show that they have at least one specialty such as, intelligent in calculating, drawing or playing musical instruments. This syndrome call Aspergers syndrome. Mostly, males suffer from this disease more than female. Nowadays, the hot and controversial topic could be why autistic problems exist in male more than female? In fact, different perspectives view autistic problem in different way. Besides, biological factor, it has Brian cognitive neuroscience to explain autistic problem. In this perspective, they believe autistic problem cause by th e abnormal functioning in the brain such as, hormone imbalance or brain damage. Somehow, in case studying, it still exist the cases who become autistic children by environmental factors such as food nutrition. From 20 century 90s Norway and British experts discover some nutrition will cause or worse the autistic syndrome. For example, the protein which contains Gluten protein and Casein protein will cause the autistic problems; because their body cannot digest or dissolve this kind of protein. But I will not discus in here. Until today, it is still unknown what exactly cause autistic syndrome. In human development, I am going to observe my object whose name is Z.H. The objective whose name is Z.H was born in 2004 in a Chinese family; after two years his parents realized his was not able to verbalize. After medical checkup, doctor said Z.H has autism. For these years, Z.H has been to many developmental therapies and special education to learn some certain manners. The therapies are broken down into several parts; most of them are activities to establish a childs connection between mind and body. In this year, my object is going to be seven years old; he is going to enter the stage call middle childhood. This studying is going to analysis this person in psychosocial, cognitive development. And I will provide some studying data as a reference. Human development: In the first three months to twelve months, you already can tell the difference between autistic infants and other infants who do not have autistic problems. In attachment theory, infants need several steps to form attachment, they are pre-attachment phrase, attachment in making, clear-cut attachment phrase and last one is formation of reciprocal relationship. Infants who do not appear separation anxiety could be autistic infants which was develop in the third phrase-clear-cut attachment. Once they fail to develop in the third stage, so they will not display separation anxiety. However, they still can develop the next stage of attachment-formation of reciprocal relationship. They are able to negotiate with their caregiver, but they develop this concept very lately. And they could not establish the third stage of attachment, so in the fourth stage of attachment child will display wired behavior such as; tend to use non-verbal communication often. For example, Z.H used to hold his moth ers hand to point to the cookies. This means that he wants to eat cookies. Autistic infants also reject to form eye-contact with their parents and strangers. In cognitive development, this stage people develop important sense of object, we call object permanence. In Piagets object permanence experiment, the important thing is not children are able to find a hidden toy or object. It is they develop a sense of expectancy. Expectancy is the basic concept to develop and it would influence logical thinking in cognitive development, which is why some autistic children are highly intelligent even though they fail to develop psychosocial development. Expectancy is a flexible concept, it has multiple functioning. For example, it can also function at psychosocial development to develop sense of empathy, but this hypothesis need to do further research. Cognitive neuroscience approach: Basically, cognitive neuroscience experts come out with three main theories to explain why autistic children could not understand other peoples intention, why they have narrow habits and how does cognitive development influence their behavior. They are the theory of mind, weak central coherence theory and central control functioning theory. To understand other persons thought, belief, and emotion, we called the theory of mind. Unfortunately, these people who suffer from autism spectrum disorder fail to develop this concept. Besides, in infancy and toddlerhood, people develop the sense of empathy. Empathy has the same function with theory of mind. According to neo-Piagetian, they believe theory of mind is a byproduct from hypercognition. Because of these reasons, autistic patient tend to be social isolation due to they do not know what other people think or look at them. In school play time, their playing styles tend to be parallel play; it means that they do not communicate each othe r and play on their own. Although their school teacher arranges cooperative play for them, they still like to play their personal stuff. The other theory says that autism spectrum disorder patients behavior just similar to the patients who have frontal lobe damage. These people weak at central control function. Central control function includes the hypercognition process of the flexible behavior and suppresses inappropriate behavior. This can explain why autism spectrum disorder patients like the unchangeable routine, do the same behavior. In psychoanalytic, they said this kind of behavior exists because they use the defense mechanism-fixation. But Central control functioning theory could not explain why they have intelligent ability in some area. Central coherence theory suggest that our sensory perception percept the whole thing. For example, when we see a picture, normal people would prefer to see the whole thing and then focus on the detail in the picture. However, autistic chil dren would see the picture in detail fast and then focus on the whole picture. In their sensory perception, a part is greater than its sum, we call they have weak central coherence. According to this theory, people designed the experiment to analysis autistic children, such as sea taste like salt and ____. Autistic child would write pepper, because pepper has strong correlation between salt. Overall, the theory of mind can tell us why they are difficult to make friends. Weak central coherence theory tell us why their sensory perception so narrow. However, according to research report, most people who success in field would have autistic syndrome, because they only focus on one thing. People who have autism spectrum disorder would appear these symptoms which I expect to happen 1) repeat behavior exist over time 2) very narrow or persist to one habit 3) insist of old routine 4) using non-verbal communication more often 5) prefer to stay alone 6) very dependent on parents or elders help Interview with Z.Hs mother: DATE: March 24th Time duration: 15 minutes Place: Z.Hs home Q1: When did you discover Z.H has autistic problem? A: we discover he had autistic problem when he is twelve. Q2: When Z.H was infancy, what was his reaction when you move away? A: He will feel uncomfortable and anxious when I move away. Q3: What is his common behavior in the house? A: he used to hang around and jump a lot in the house. After, we went to the therapist, this behavior become less and less. Q4: What does he behave at the school, such as does he have any friends at the school? A: No, he does not have any friends at the school. Q5: Could you tell what kind of playing style he prefers at the school? A: He prefers to play alone. Q6: Does he recognize himself from the mirror? A: Yes, of course. Interview with Z.H: DATE: March 24th Time duration: 15 minutes Place: Z.Hs home Q1: Do you miss me when you see me? A: miss Q2: Can you come here? I want to give you a hug. A: (He really come to my side and let me give him a hug) Note: when I interviewing Z.H, he had difficulty to form an eye-contact communication with me Observational Studying in Occupational Therapy Classroom DATE: January 28th Time Duration: 3 hours Place: classified Number of people in the room: 3 people ( therapist , Z.H, and me) Physical Therapy breaks down into several steps. Mostly, it is designed to train childrens motor movement. Therapists use two rooms to develop Z.Hs motor movement and cognitive development, one is physical therapy class room, and other is monitoring room which means that students learn academic skill from monitor. The sections in cognitive development, therapists guide Z.H to establish recognition, verbalization and sense of hearing. In physical therapy section, therapists also guide Z.H to develop his motor movement in balancing, stimulate in his sensory perception. Meanwhile, they teach some simple commands and morality to Z.H. During this section, I could see Z.H repeat behavior which is jumping.But, I could not say when this behavior exist what was his emotion status, such as happy, angry or depression. Z.Hs Attention through the Observational Studying Since therapy break down into several steps and in different rooms, the result will be break into two: the attention in physical therapy classroom, and monitoring classroom. In physical classroom, there were five components to accomplish basically. And Z.H showed that he could not focus on his task. Because I noticed that he liked to focus on things which he interest in or moving objects. During these components, Z.H tried to operate the radio which was located at the corner. His concentration in physical therapy classroom approximate five to fifteen minutes. The activities in monitoring classroom are break down into three components basically. Therapists let students sit in front of the monitor to learn some simple vocabulary. If students really participate in this section, they finish one level. During the monitoring learning section, Z.H showed his strong interested in monitoring learning. So in this component, I did not see any attention deficit syndrome appear. However, in the s econd component which was not relate with monitor, he show this syndrome again, because I saw he try to operate DVD player for several time. Even though his therapist prohibited him from operating DVD player, he still tried to do so. In this all section, Z.Hs faced the difficulty on concentrating due to he had interested in operating mechanical item. Analysis and Discussion: In the analysis and discussion this section, I should analysis this object and chase back in human development by using the data which I have already collected. Firstly, according to attachment theory Z.Hs case I think it could be counted as an exception if I only use one perspective. He suffered from separation anxiety when he was in infancy stage. However, I do not think it that way. During the interview section, I ask his mother about separation anxiety. The result shows that it is negative (see the interview with Z.Hs mother in question 2). I believe the reason could be mothers self-esteem effect, memory processing problem and personal defense mechanism. In environmental factor to influence this effect, I think it is high social economic status and siblings or familys pressure. But, I will not discuss how social economic status influence high self-esteem in family. I will discuss how siblings and family influence mothers high self-esteem. In her family, Z.Hs problem is very rare and his brothers and sisters do not carry this kind of syndrome. Z.Hs cousins do not have this problem as well. Since, Z.H was analysis he has autistic spectrum disorder, his mother felt very depressed and guilt for a period. This could be a nurture factor to influence mothers reaction to my survey and memory process error. Before I start discussing how nurture factor influence memory, try to answer this question Could you tell me the traffic lights position in Malaysia, is that red light on the top or on the bottom. The same concept to apply memory processing theory, peoples sensory perception is selective. I could assume that Z.Hs mother was stereotypingmost of the infant will get anxious when the mother is moving away from them. She uses that concept to answer my survey or she forgot what Z.Hs reaction when she moved away. Also, her hope and wishes could manipulate her memory, but I will not discuss here. The last reason could be the interview technique that I did not notice. Fir stly, the interview styles that I used tend to be straight forward. Some people may scare about that. The ideal technique should be slow approach. It means that a goal can be divided into several steps to accomplish. For example, I should not have asked the question directly, first thing I should do is to ask the things happen around Z.H to reduce mothers defense. Also, this technique can let his mother chase back his infancy and toddlerhood stage. In other words, I could get a result which is more accurate by using this slow approach technique. Z.H is a six-year-old boy. The stages he went through are infancy and toddlerhood. Since he suffered from separation anxiety, I think I cannot explain Z.Hs behavior and emotion status by using one approach of developmental psychology. Erick Ericksons psychosocial psychology can explain that if I combine with attachment theory. In fact, I assume that the original source of attachment theory is from Erick Ericksons psychosocial. Firstly, at the first stage of psychosocial stage called basic trust and mistrust. It says responsive care giving will let infants form basic trust. I can say Z.H already in basic trust that can explain why he could suffer from separation anxiety. At the interview section (interview with Z.Hs mother question 6 and interview with Z.H question 2 p.6 and 7); I can say Z.H developed a sense of self-awareness and self-consciousness. His mother said he can recognize himself in front of the mirror, and he understood I was talking to him and giving him a command. In cognitive development, Z.Hs situation is that his linguistic development shows delay because he is an autistic child. In the interview (interview with Z.H question1 p.7), I can say his linguistic development stay at one-word speech. This is common problem in autistic children-linguistic delay. Somehow, Z.Hs face social shut down problems because he do not form eye-contact communication with others, and his playing style tend to be parallel play(interview with Z.Hs mother question 5 line14 p.6). The theory of mind explains why he prefers to play alone, because he does not understand what other peoples intention. During the observational studying section, I observed that his repeated behavior is jumping. Actually, repeated behaviors dependent persons personal background. For Z.Hs case is jumping exists over time, in central control functioning theory (intro page5 line 6) can explain this. But if I want to enter further such as why central control functioning theory causes this problem exist; I may need to do further study. Also, he showed a strong interested in operating mechanical items, such as radio and DVD player (observational section p.7 and 8), even though therapist asked him to stop it. Apparently, he has not developed or weak in sense of effortful control, in psychoanalytic approach, his ego still underdeveloped, because his structure of personality still work on pleasure principle-the needs must be satisfied immediately. Frontal lope will be well-developed when people reach early adulthood. It controls our compulsive problems. That is why Z.H insists of operating radio and DVD playe r even though therapist was not allowed. Also, reticular formation controls our attention. It is not surprise to see Z.H face the challenge in attention, because this part of brain will be well-developed after people reach puberty. And, this studying only take one day, some result cannot say accurate. For instance, weak central coherence theory (intro page 5 line12), this theory may require responsive observational studying. Basically, it says in autistic patients their sensory perceptions tend to be more selective. In one sentence, a part is greater than its sum. During the monitoring section, I discovered that Z.Hs problem. Z.H was born in Chinese a family, therefore, his native language is Chinese. In the word matching, therapist said a word or a vocabulary in Chinese to let Z.H to match the word, and the word cards was on the floor. For example, if therapist said stamp, Z.H had to find the card which represent the word stamp. In Chinese pronunciation, each word has different pronunciation. His was able to detect the number of words which was said. For example, if therapist said black broad which translate to Chinese are two words. He would choose the word cards which contain two words in Chinese, but word did not mean black broad. He could choose the word stamp instead. This incidence told me that Z.H is developing a sense of understanding what other people say. But he did it in different manner, in his world, he focus on number of words, not meaning of words. Over all, in the result analysis I discover it is not enough to use only one perspective to explain and analyze human development. Z.Hs case counts as a special case because he was born to be autistic child. The behaviors he occurs are repeated behavior, attention deficit, and delay in linguistic development. Therefore, I use combination of different approaches to analyze Z.Hs case. For example, Erik Eriksons psychosocial combine with attachment theory and effortful control joint with psychoanalytic approach. These approaches have common connection with human development. Conclusion: In this research paper, it focuses on external behavior to explain inner personality or self in human development. However, it still has limitation. For example, I could see what really happen in Z.Hs mind and his cognitive thought. I know this papers weakness could be the motivation and introspective part. What drive Z.H to operate the DVD player, although therapist asked him to stop? The second thing is that expectation problem. I believe in human development, the first cognitive developmental concept that children develop is expectation and then it transform to empathy. However, I have lack of evidences to support this hypothesis. I think may be humans mind is too complex to explain, even if we have fMRI and PET scanner. They only can tell what happen in the brain, instead of what happen in the mind. But, I know one thing is definitely is that Z.H is getting better after he join the physical therapy section. His mother said that he could tell a single word, before he went to thera py. It is not a shame to get autistic spectrum disorder; it is people ignore the existence of the problem. Actually, the number of curing autistic children is increasing. In China, their therapy section is based on make-believe play-role play. It combines with Piagets concept and Banduras social learning theory to cure the children who suffer from autistic spectrum disorder.

Intensive Critical Care Nurse 22(2) 115-21 Introduction The aim of this critique is to identify the stages of the research process in the above article by Wheatley (2009). According to Preston (2010), being able to critically read research based literature is an important skill in reviewing literature sources that are presented in all academic assignments. This activity is an opportunity to examine the strengths and weakness of a research study in relation to the research process steps ( Priest et al, 2007). The critique will consider the nature of the survey approach to research and to compare this to how Wheatley (2006) designed his project. As this article reports on a survey research study using an observational method, it is important to examine the key features of this research design. Therefore the strengths and weaknesses of the research process featured in this article will be discussed. This will include an appraisal of the sample size; data collecting tool and process of collection, the research findings and their relevance to nursing practice. This article reports on a survey type study that utilises an observation data collecting tool. According to Pollit and Bek (2010) surveys are used widely in health care research and are effective for examining a wide number of problems. In this article by Wheatley (2006), the survey is used to discover what nurses actually do when they conduct clinical observations in a medical ward setting. The aim and research questions he identified in the article are clearly written and follow a positivistic, deductive paradigm that is appropriate in a quantitative research study of this type (Gerrish and Lacy, 2006). According to Lobiondo-Wood (2010) a positivistic paradigm considers that what can be seen can be measured. The findings are always presented in number formats. In this article Wheatley (2006) is using an observational tool to view the conduct of nurses undertaking clinical recording of vital signs. This tool would have been structured so that identified behaviours could be investiga ted. Although the data collecting tool was not presented in the article it is clear from the discussion that the tool set about to observe the accuracy of nurses recording blood pressure, temperature, respirations and pulse. The tool also identified which nurses undertook this activity and the time that they took to complete a set of observations for each patient. Priest et al (2006) identify that all researchers need to plan their research studies on a sound review of the literature underpinning the research problem. According to Pollit and Bek (2006) the literature review will provide background information on the problem and will identify what research has already been conducted. In this article Wheatley has presented a review of the literature and it is clear that he has based his study on similar studies conducted in the past. His reference list provides a selection of different literature sources and includes 46 sources that are clearly focused on recording vital signs and 2 on research methodology. This clearly indicates that Wheatley (2006) has structured his study on a sound review of the literature. The sample size in a survey research study has to follow the nature of the quantitative, positivistic approach (Pollit and Bek). This means that the sample size must be large enough to represent the general population it is representing. In this article, Wheatley (2006) has reported on observing 20 cases of nurses conducting observations. This is a very small sample size and statistically would not be considered a positive representation of a good research plan to have such a small for a survey project. However, Wheatley (2006) clearly identifies the limitations this posed to his study and explained that the small sample size was a convenience sample that was appropriate for his planned study. According to Polit and Bek, (2010) a convenience sample is acceptable as it represents the whole population. In this case, Wheatley (2006) has included all the nurses who work on one ward and found that in 18 out of 20 occasions he observed, it was the machine that dominated the recording of pa tients vital signs and that the time nurses spent with the patient was dependent on how long it took the machine to do its job. In 16 occasions, nurses did not record the respiratory rate even when 4 patients were showing signs of respiratory distress like dyspnoea or coughing. Therefore, although 20 in a sample is not considered viable for a survey type project, the use of a convenience sample (Pollit and Bek, 2006) in this case, provides the reader with a strong indication that there are problems in how nurses undertake clinical observations as part of their acute illness assessment. However, for this finding to affect a change in future nursing practice more research using larger sample frames would be useful. The data collecting tool and how data is collected in a study (Priest et al, 2007), is also another important step to appraise in a report on a research study. In this article, Wheatley (2006) has designed an observation tool using structured observations that included time taken to record vital signs; which nurse undertook the assessment (ie qualified or HCA); whether a machine or hand/touch methods were used to record pulse and respirations in particular; how vital signs were recorded on the observation charts. According to Polit and Bek (2006) a good research paper will show the reader how they structured their data collecting tools. In this article, it is clear to see what was observed by carefully examining the graphs and table charts Wheatley (2006) presented in his findings section. At the top or bottom of each chart he writes what behaviour/activity was recorded in his findings. For example, one chart on page 117 has the title which nurses performed the observations and you c an see that of 20 only 2 observations were carried out by a qualified nurse. The other 18 were conducted by the HCA. What Wheatley doesnt do however in his article is consider if being observed in this study changed the nurses behaviour. Polit and Bek (2010) note that in observation studies bias can occur through the Hawthorne effect. This is an effect noted to occur when people realising they are being watched change their behaviour during that process. However, there is no indication this happened here and one can assume therefore, that the behaviour Wheatley (2006) observed was what would normally be expected in patient observation activities. When appraising research papers, Ryan et al (2007) say an important step in this process is to review how well the researcher has presented his findings. In this article Wheatley (2006) has utilised descriptive statistics in a clear format that is easy for the reader to understand. He has used descriptive statistics to convey the findings in simple percentage and number format. For example, it is clear to see that most observations are carried out by HCAs (n =18 or 90%). When numbers are expressed like this it clearly indicates the power of that finding (Polit and Bek, 2010). Another important finding is that in 4 cases nurses failed to record the respiratory rate even when patients were struggling to breathe. Although this is a small percentage (ie n = 4 / 20%), it is worrying to note that any nurse would fail to record the respiratory rate when a patient is clearly showing signs of distress. From these findings, Wheatley (2006) concludes that qualified nurses must take responsibili ty for taking and reviewing how vital signs are recorded in acute care settings if patient safety is to be safeguarded at all times. Overall, the article by Wheatley (2006) is a good example of a research project using a survey method approach to study. Despite noting a small sample frame that could indicate a bias to how the findings can be appraised, it is felt the findings are generally credible and should be appropriate to both inform nursing practice and promote patient safety in acute illness assessment. The steps of the research process are clearly identified throughout the article that demonstrates the researcher has understood how a survey research study should be competently planned for and undertaken and reported on.

Show how Blake creates opposing attitudes and ideas in his songs of Ess
Show how Blake creates opposing attitudes and ideas in his songs of Innocence and Experience. Show how Blake creates opposing attitudes and ideas in his songs of Innocence and Experience.David Jessup 11A1 Blake creates opposing attitudes and ideas by using contrasting, emotive language and also by using characters with opposing opinions and attitudes. In "The Chimney Sweeper" Blake uses characters with different situations and lifestyles to show how distraught the chimney sweeps can be when they are sent away from their families to work at a very young age. In "The chimney Sweeper from "Songs of Innocence" the young boy is described as an "angel" and also as a "lamb", both often used as symbols of innocence and purity. Blake uses symbols of innocence as an alternative way of describing the children as innocent. He used various similes and metaphors in the Innocence poems to make the poems more light hearted and to also convey a sarcastic tone because of the obviously false descriptions. "All of them in coffins of blackà ¢Ã¢â€š ¬Ã‚ ¦an angelà ¢Ã¢â€š ¬Ã‚ ¦opened the coffins and set them all free", the coffins of black suggest that by fulfilling their tasks as chimney sweeps the children are going to their eventual death from suffocating or some other form of detath in the dark, smoky chimneys. With language like this Blake managed to portray his beliefs without going against the Church or the State directly. This meant that although he was criticised he could look at both sides of the lives of children without being accused of being single minded or patronising. In "The Chimney Sweeper" from Innocence the narrator is the chimney sweep himself; this is an effective method because Blake can then use the child's... ...he year that orphan children are paraded through the streets in bright colours as soldiers. Blake uses this viewpoint so that a neutral opinion can be gained of both a sinister viewpoint of the parade and a gratuitous viewpoint. "With wands as white as snow," show the beadles as pure and leading the children in a good cause but in Experience the beadles are shown in a different manner. "Fed with a cold and usurous hand?" showing the beadles cruelty and content to be selfish and treat the children as objects not human beings. The poem I like best of all six is "The chimney Sweeper from Experience because it takes the misuse of chilren in a bad situation and describes it in an even darker manner. "They clothed me in the clothes of death", the childs knowledge is invaluable that he knows of his inevitable detah even though he is only a young child.

Pollution Essays -- essays research papers
Pollution, contamination of Earth's environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities. There are two main categories of polluting materials, or pollutants. Advertisement Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose (see Sewage Disposal). Nondegradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment. Nondegradable compounds such as dichlorodiphenyltrichloroethane (DDT), dioxins, polychlorinated biphenyls (PCBs), and radioactive materials can reach dangerous levels of accumulation as they are passed up the food chain into the bodies of progressively larger animals. For example, molecules of toxic compounds may collect on the surface of aquatic plants without doing much damage to the plants. A small fish that grazes on these plants accumulates a high concentration of the toxin. Larger fish or other carnivores that eat the small fish will accumulate even greater, and possibly life-threatening, concentrations of the compound. This process is known as bioaccumulation. II. Impacts of PollutionPrint section Because humans are at the top of the food chain, they are particularly vulnerable to the effects of nondegradable pollutants. This was clearly illustrated in the 1950s and 1960s when residents living near Minamata Bay, Japan, developed nervous disorders, tremors, and paralysis in a mysterious epidemic. More than 400 people died before authorities discovered that a local industry had released mercury into Minamata Bay. This highly toxic element accumulated in the bodies of local fish and eventually in the bodies of people who consumed the fish. More recently research has revealed that many chemical pollutants, such as DDT and PCBs, mimic sex hormones and interfere with the human body's reproductive and developmental functions. These substances are known as endocrine disrupters. See Occupationa... ...es of excessive noise. Page 1 of 2 See an outline for this article.
