Blood Groups and Transfusions essays

Blood Groups and Transfusions essays When Europeans first experimented with blood transfusions in the 17th century, so many patients died that the procedure was outlawed in England, France and Italy. It is said that the Incas in South America began transfusing blood much earlier, and that fewer deaths resulted. If so, the reason, not understood at the time, may have been that nearly all of the Incas belonged to the same blood type, while the Europeans, like most groups of people, belonged to different and incompatible types. Today, blood transfusion is safe only because blood samples from the donor and recipient are tested to ensure that no dangerous transfusion reaction can occur from the In the ABO system, human blood is classified into four types: A, B, AB, and O. If your blood is type A, your red blood cells carry a protein called Antigen A and your plasma, a protein called antibody b. If you are type B, your blood contains antigen B and antibody a. Blood type AB carries both antigens but no antibody, while type O blood has neither of the antigens but both of These categories are important in transfusion because certain antigens and antibodies are hostile to each other. Shaped so that they can lock together, mutually hostile antigens and antibodies adhere in clumps that can cause fatal blood-vessel blockages. Generally, people with type A blood can safely receive blood from As and Os, while type B recipients are safe with blood from Bs and Os. People whose blood types is AB are known as universal recipients, because their blood is compatible with types AB, A, B and O. Type O people, on the other hand, are safe only with blood from type O donors, but they are themselves so-called universal donors, because they can give blood to anyone. In a routine count the bloods basic components, red cells, hemoglobin, whil ...

Epithet in Homers Iliad and Odyssey

Epithet in Homers Iliad and Odyssey Usually called an epithet or a Homeric epithet, but sometimes called a Homeric epitaph, it is one of the most noticeable features of Homers Iliad and Odyssey. Epithet comes from the Greek for putting (something) on (something). It is a tag or nickname that can be used on its own or together with the real name, depending on other features of the Greek language. Purpose and Use Epithets add a bit of color and also fill out the meter when the name on its own doesnt quite fit. In addition, epithets serve as a mnemonic device reminding listeners that they have, indeed, already heard mention of the character. The epithets, generally compound adjectives, are picturesque, which certainly helps make the assignment of character to epithet memorable. Examples Most of the important people in the Iliad have a special epithet that serves as an extra name. Athena is the only one described as glaucopis grey-eyed. She is called thea glaukopis Athene goddess grey-eyed Athena and also Pallas Athene Pallas Athena. On the other hand, Hera shares her epithet leukolenos white-armed. Hera does not, however, share the longer epithet thea leukolenos Hera goddess white-armed Hera; nor does she share the epithet bouopis potnia Hera cow-eyed mistress/queen Hera. Homer never calls the Greeks Greeks. Sometimes they are Achaeans. As Achaeans, they receive the epithets well-greaved or brazen-clad Achaeans. The title anax andron lord of men is most often given to the leader of the Greek forces, Agamemnon, although it is also given to others. Achilles receives epithets based on the swiftness of his feet. Odysseus is polutlos much-suffering and polumytis of many devices, crafty. There are other epithets for Odysseus beginning with polu- many/much that Homer selects on the basis of how many syllables he needs for the meter. The messenger goddess, Iris (note: the messenger deity is not Hermes in the Iliad), is called podenemos wind-swift. Perhaps the most familiar epithet is the one used for the passage of time, rhododaktulos Eos rosy-fingered Dawn.

Lobbying as Legitimate Aspect of Corporate Behavior Essay

Lobbying as Legitimate Aspect of Corporate Behavior - Essay Example It is a deliberate attempt on part of the lobbyists with the motive of influencing political decisions using various forms of advocacy and it is directed at the ones who form up these policies on behalf of another person, organization and/or group(s). There are clients who are either individual beings or organized interests such as businesses organizations, labour unions, organizations who work as not-for-profit and trade associations who hire lobbyists who do their work for them. In the organization, the lobbyist is hired in the Government Relations function or they can even be outside individuals or firms (Wood, 2002). The main purpose of the lobbyist is to develop various strategies and tactics so as to gain access, inform, influence and pressurize. These methods and strategies can be developed by designing a lobbying campaign. Lastly, it should be known that these lobbying campaigns are directed towards policy makers whose job is to make policies which affect the well being of th e client, the European Union public, all sorts of communities which exist on local, national and international levels plus the president and the future generations to come. Since their decisions affect a whole variety of people, lobbying is playing a very important role in this process. There can be many methods in which lobbyists do this. For example, they can do this by using their personal reputation, out of professional obligation or the rapport that they have cultivated overtime. These means are used to achieve political goals such as gaining the trust of the authorities so as to gain access so that the lobbyists can share his opinions and viewpoints which will influence their decisions in the making of the public policy (Wood, 2002). There can be other types of influences as well such as positional influence which depends on the place that a lobbyist has in the public realm in which he is expressing his viewpoint. (Karen, 1978) Moreover, it is a term which is highly controversial and is always regulated by the Government and specifically defined so that organized group lobbying does not take a negative aspect and misuse this term. The term lobbying has originated from the concept of everyone sitting in the lobbies and having a discussion before and after parliamentary debates in the Houses of Parliament. These discussions usually gave way to the fact that certain legislators could manipulate or influence others without even them knowing that they are getting influenced by the discussion. Lobbying is a very subliminal process. Clever and ethical lobbying results in winning a lot of thing for the organization, such as better strategies, efficient resources, fruitful recommendations for the company and helps in the compliance which is ongoing. Lobbying has always been a controversial term in the sense that people tend to think it leads to corruption and this is not false. Lobbying can change the mind set of an individual to a mind set that the individual himself does not want to adapt to. Therefore, many jurisdictions have been created which require that men who are playing the role of lobbyists get themselves formally registered with the authorities before they come in contact with the Government representations that they

Wage and Price Rigidity or Stickiness Essay Example | Topics and Well Written Essays - 1000 words

Wage and Price Rigidity or Stickiness - Essay Example It does not affect the real flow of output but rather, surprises and stabilizes the economy. It implies that in a place where the population has rational expectations, government policies which are made to influence the economy into a level of production will never be effective. Rational expectations first became a big factor in the policy activism debate in the early 1970s when Thomas Sargent and Neil Wallace wrote their famous policy ineffectiveness paper. They showed-using an elementary macroeconomic example based on Robert Lucas's then new model of the Phillips curve-that an active monetary policy could not be effective in stabilizing fluctuations in output and employment. (Taylor) Implicit wage contracts is when workers are risk averse and employers are not, an implicit contract may be made with an understanding over "compromise" basic pay and hours. This may or may not generate nominal wage rigidity. Contracts like this may be non-implementable if there is asymmetric informatio n. Nominal price rigidity () tests for downward nominal price rigidity. Intuition: deflationary shock, some prices not cut as there is a zero price floor; across sectors "we would expect to observe a negative correlation between mean inflation rates and the skewness of inflation". (2005) Once the place and manner of nominal wage rigidities in the economy have been specified, the model must explain why rational workers and firms enter into arrangements which may impose a macroeconomic externality and allow the economy to deviate from the natural level of output. (pg 7) Because it is advantageous for firms to enter into long-term agreements on the price of their purchased input factors, there is also price rigidity in the input factors markets. Moreover, the commonly used procedure of firms to adjust their output price in constant proportion to changes in the price of input materials and labour costs - the notion of markup pricing - will result in rigid output prices as well. (pg 9) According to Piere Siklos, policy ineffectiveness proposition predicts the absence of an exploitable output-aggregate demand trade-off by policymakers. Therefore, when individuals are assumed to form expectations rationally (that is, they process all relevant information at their disposal), only unanticipated policies can influence output. (249) Dennis W. Carlton and Jeffrey M. Perloff (2000) quoted Stigler (1947) that prices are relatively rigid in an industry in which there is a dominant firm that exercises price leadership. That is, there are relatively few changes in prices. In his classification, an industry has price leadership if there is a relatively large firm, "producing, say, 40 per cent of the output of the industry at a minimum, and more if the second largest firm is large ..." (p. 228). Just before the new Keynesian model was formulated, it was believed that the formulation of government policies does not have any direct effect on wages and prices in the market unless a surprise monetary policy was released and discloses the economic status in a short wile. It was also believed

Cognitive psychology Essay Example for Free

Cognitive psychology Essay Cognitive psychology focuses on how a person interprets a picture or message. For example, a double figure drawing such as the top down example below is one part of the cognitive thinking process. Another mental exercise is the bottom-up perception of drawings and messages.   Often times, the judge in court cases would ask the professional interpretation of the psychologist to help mitigate or aggravate the current sentence of a criminal offender. The following paragraphs explain in detail what cognitive psychology means. 1. what advice would you give a judge to persuade her or him of the potential danger of wrongful conviction based on eyewitness testimony as the sole or primary kind of evidence? Support your claim using cognitive psychology research. The judge should not base his sentencing only on the sole eyewitness’ statement. For, the judgment should be mitigated or aggravated by the professional opinion of the psychologist.  Ã‚   It is a standard procedure for the U.S. judge to ask the Forensic psychologist  Ã‚   to give a psychological profile of the defendant. The psychologist will then make a profile of the psychological well –being of the person charged in court. The psychologist then applies the theories of cognitive psychology to determine the behavior, pathology and motivation and submit his findings to the judge. The judge will then include the psychologist’s professional opinion increase the defendant’s sentence for aggravating reasons (Burke 1). On the other hand, the judge could also decrease the defendant’s sentence for mitigating reasons. And the psychologist’s findings will be used either as an aggravating or mitigating evidence.   Normally, the psychologist can draw up the behavioral tendencies of the defendant by viewing the other evidences on the crime scene, the statements of various witness, friends, neighbors and relatives and prior psychological findings.   The psychologist is very much needed in the juvenile courts because the child’s behavior is not as mature as those who are eighteen yrs old and above. Generally, the juveniles commit crimes because of their psychological growth is not normal ( or abnormal?), The psychologist can recommend to the judge to transfer the child to child rehabilitation center for psychological rehabilitation(Barsalou 5). Likewise, the psychologist can persuade the judge to lessen the sentence in adult criminal cases.   The psychologist can opine that the sexual offense was psychologically caused by the defendant’s state of mind at the time of the crime. He or she could have been abnormal then. The psychologist can recommend a plea bargaining agreement with the Judge using his psychological findings in order to reduce the sentence that has been mandated by the criminal laws of the United States( Berger 10). In addition, the psychologist can issue his opinion to the courts regarding the reliability of the lone witness’ psychological profile. For, the witness may not qualify as a lone witness if the psychologist opines that witness’ statements were hallucinations, a big lie, or simply made because of the witness had misinterpreted the situation as what is was not. The psychologist will then assess the stimuli response   makeup (cognitive psychology) of the offender. The psychologist can also assess the criminal offender’s impulse control and potential for the individual to commit crimes. Likewise, the psychologist can opine to the judge that he defendant cannot psychologically defend himself or herself in the witness stand (Gillespie , 27). This will then be a ground to decrease the sentence of the defendant upon conviction. To reiterate, the psychologist can tell the court that the defendant was psychologically abnormal when he or she committed the crime. Thus, the judge must compulsorily use the psychologist’s evaluations of the defendants and the witnesses to plug the holes in his sentencing process. Also, the sex offenders would need the psychologist’s hand to help them. The psychologist would then tell the court that the sexual offender’s sentence be reduced to being jailed at the Adult Diagnostic and Treatment Center.   The psychologist would go about by stating that the defendant’s psychological makeup is the main cause of his continuing spree of sexual abuse cases. 2. Describe what implicit memory is. Based on Reber (1993) how is implicit learning and memory different from explicit learning and memory. Implicit memory states that prior experiences affect the current behavior of a person even though the person does not intentionally exert a single effort to ponder over his or her prior experiences.   Likewise, repressed memories of the past are equated with implicit memory.   For example, improving ones’ job performance falls under implicit memory and learning. This is the main reason why many companies prefer to hire and give higher salaries to people who have many years of hands –on experience behind them when they apply for a job. Definitely, a carpenter that has worked in house construction for the past twenty years would definitely be more skilled than a carpenter has tucked under his belt only one week’s hands –on experience.   Whereas, explicit memory is the conscious and intentional recalling of a person’s past experiences and informational data (French 26). A very clear example is trying to remember what today’s itinerary or hectic schedule is.   It would include a ride in the park with the family, a meeting with the board of directors in the company, or a customer dropping by to purchase new products. Another is trying to recall the details asked for in the Civil war classroom test. Further, trying to recall the ATM password or the email address log –in username and password when withdrawing money from the ATM machines falls under Explicit learning and memory. In short, explicit memory and learning entails effort exertion which includes thinking about one’s past experiences.   It also includes talking about one’s past experiences and writing them done. Further, it includes studying ones’ past experiences. For, they will surely increase one’s expertise on doing a specific job assignment (Esgate 15). Reber stated that implicit learning refers to the variances in the behavior of a person that is influenced by past experiences. However, the person is not aware or exerts effort to try to recall the past experiences. Reber proved his theory through countless experiments including probability learning.   His probability experiments prove that the subjects were able to recognize or learn the variance in probabilities of recurring events without their knowing that their prior experiences in the same situation have improved their changes of choosing the next probable event. One Reber experiment shows that the subjects were placed in a training phase. The subjects were told to observe   1,000 scenes at the rate of two scenes in one second in one experiment. The findings of this experiment shows that the subjects were able to learn what the next outcome would be in increasing accuracy as the test went on (Reder, and Schunn 46). Another Reber experiment shows that a person that solves several problems of the same will increase his or her speed and accuracy in solving such problems due to experience. However, the subjects were not aware of that their prior acts had influenced their current speed and accuracy. This is very true in classroom math exercises (Reder, and Schunn 69). Reber further emphasizes that memory and learning consists of conscious (Explicit) and unconscious (Implicit) learning processes (OBrien-malone, and Maybery 38).   And, Reber insists that the questionnaire index test is an explicit learning process (OBrien-malone, and Maybery 38). 3. Define what cognitive psychology is about. Cognitive Psychology is that branch of psychology that delves into the process of how a person uses his mind to find solutions to problems, memory as well as communication. It had metamorphosed from the Gestalt school of Max Wertheirmer, Wolfgang Kohler and Kurt Koffka. However, it was Jean   Piaget who increased interest in Cognitive Psychology with his theory that people have different cognitive processes from infancy to old age. Naturally, he emphasized that child cognitive learning is much different from a married person’s cognitive learning. Going deeper, cognitive psychology involves how the brain solves mathematical and other real life problems. And, the cognitive scientists believe that the problem solving cognitive process boils down to the basic stimulus and response theory.   For, each stimulus gives different responses to different people (Fleck, 6). What are the main topics? History. Cognitive psychology had branched out from mainline psychology into its own specialized field in the 1950s and 1960s as discussed in Donald Broadbent’s masterpiece entitled Perception and Communication in 1958.   It focused on the processing of information with the incorporation of Donald Broadbent’s paradigm theory. Basically it was a study on how a person thinks and reasons as he tackles each problem or situation in real life or in the classroom. Broadbent emphasized that the brain is a the central processing unit of the human being.   Then, George Miller created the WordNet which is the foundation for many machine ontologies today. This was also the basis that has permeated from cognitive psychology to other fields like social psychology, personality psychology, abnormal psychology,developmental psychology.   Currently, current cognitive theories are being attacked from many sides. One such side is the dynamic system proponents. Further, cognitive psychology has gathered the fruits of researches in artificial intelligence and other fields of expertise in the 1960s and the 1970s (Esgate 15). Major research areas.   Currently, the major research areas of cognitive psychology are general perception, psychophysics, attention, pattern recognition, object recognition and time sensation (Berger ). Cognitive psychologists.   The list of cognitive psychologists continues to grow through the years. Some of the more famous ones are Johan Anderson, Robbie Case, Lev Vygotsksy, Alan Baddeley, Frederic Barlett, Aaron T. Beck, Donald Broadbent, Reber, Jerome Bruner, Fergus, Craik, Keneth Craik, Hermann Ebbinghaus. Albert Ellis, and Jean Piaglet (Berger, 4). What are some basic assumptions? Cognitive process involves a stimulus and the corresponding response to such stimulus. Basically, cognitive theory states the problems in math and other real life situations can be easily accomplished with the use of algorithm. Algorithm is the set of rules that will give a specific solution for a set of inputs. For example, one plus one (inputs) is equal to two ( the algorithm here is to count how many ones are there). Here, the rules for cognitively solving problems are rather vague or too complex for the simple -minded person to comprehend.  Ã‚   Logically, there is another way of cognitively solving problems. This is what is called in psychology circles as heuristics. In sharp contrast, heuristics shows that the rules of solving classroom and real life problems are clearly understood but the final solution varies from one situation to another. What are some of the different methods employed by cognitive psychologists? The psychologists employ several methods to deepen their study of cognitive psychology. One such method is the scientific method. Another method is to use a person’s cognitive outfit in terms of belief, motivation and desire that are part of the mental processes. But, they always use subjects in their researches on how a person interprets a picture, a messages or other types of communication signals passing his or her way.

Criminal Justice and Computers :: Technology Essays Police

Criminal Justice and Computers Technology affects almost all aspects of society today. Family life, medicine, business, telecommunications, and social life have all been changed for both good and bad. Interesting me in particular, technology (mainly computers) has influenced the criminal justice/law enforcement field. That is my chosen profession that I hope to accomplish. A few summers ago, I had the privilege to ride along in a patrol car two times with the Michigan State Police Bay City Post. As I was side by side with the troopers, I observed many things. I never knew how much they used technology. Not only computers, but other things as well. Throughout one’s shift, the officer communicates on his radio frequently. This radio can broadcast all around the county to other police officers and stations. That is the way that the word about a crime gets spread. If an officer is down, he or she can just talk into their radio and help will come as soon as possible. I thought that when the police officer pulled over a speeding car, they walked up to it, issued the violator a ticket, and went on their merry little way. I was wrong. When they first pull them over, the officer enters the license plate into the mini computer. There is a small device that is latched into the console between the seats in the patrol car. It looks like a small computer with the keyboard and screen attached together. There are many different options to choose from on the main screen. After the officer enters the license plate number, a whole bunch of information comes up. Who owns the car, the make of the car, and information similar to that come up on the screen. After the officer gets the driver’s license, he or she enters that into the police blotter also. The information that comes back now is if there is a warrant out for the driver’s arrest, if he or she has any unpaid tickets, and also all the other times he or she has gotten pulled over for traffic violations with in the past year show up. Without this technology, police officers would be in a lot of danger. There could be a convicted felon in that car, but the officer would be unaware. So with this computer, a lot of information is stored, the safety of lives is increased, and the police can find out about the driver without asking him anything.
