Discuss Plato’s Parable of the Cave. Plato’s parable of the cave, also known as the â€Å"allegory of the cave, opulently describes beneficial metaphors and elaborate imagery about knowledge, ignorance, truth and lastly enlightenment. The allegory of the cave appears at the beginning of Book VII of Plato’s The Republic, which in itself is principally a study of justice, government and leadership. In The Republic, Plato describes a cave containing individuals confined to the cave floor, bound by shackles. They are unable to move their heads and stare incessantly at the cave wall directly in front of them. The prisoners cannot see one another. Behind the prisoners burns a fire projecting images of objects, animals and individuals carrying†¦show more content†¦The analogy is attempting to encourage individuals to realize the danger of acceptance and complacency. Only when we question and search do we have the chance to become truly free. When freed from our cave - enlightenment is possible. â€Å" The prisoners initial reaction of escaping from the cave is one of fear and confusion, a desire to return to the comfort and security of what he had lived with all his life even though now he is aware it’s all an illusion†(Jackson R 23) Everything the prisoner once believed to be real is now a figment of his imagination and his past environment. This realization at first is frightening, He recognizes that the objects he now sees are real objects and what he has experienced his whole life was simply shadows. Escaping from the cave is a turning point in the prisoner’s life. His prior knowledge is questioned thanks to his heightened sense of consciousness. Plato implies people’s lives and there ability to think rationally is limited by their experiences. This phenomenon is reflecting through the shackled cave men’s lack of awareness of the world and there inability to distinguish what is real from what is not. The cave analogy explores the danger and human tendency of becoming docile consumers. Simply accepting familiarity as knowledge disallows for human growth and permits individual’s knowledge and experiences to simplyShow MoreRelatedPlato And Plato s Republic1119 Words   |  5 PagesThe ancient Greek Philosopher Plato had an interest in finding the ideal government.

Abnormal Psychology free essay sample

Abnormal psychology is the branch of psychology that studies unusual patterns of behavior, emotion and thought, which may or may not be understood as precipitating a mental disorder. The science of abnormal psychology studies two types of behaviors: Adaptive and Maladaptive behaviors. Clinical psychology is the applied field of psychology that seeks to assess, understand and treat psychological conditions in clinical practice. The theoretical field known as ‘abnormal psychology’ may form a backdrop to such work, but clinical psychologists in the current field are unlikely to use the term abnormal in reference to their practice. Disability or dysfunction. (Is there a loss of normal functioning? ) People who suffer from psychological disorders may be unable to get along with others, hold a job, eat properly, or clean themselves. 3. Personal distress. (Is the person unhappy? ) The personal distress criterion focuses on the individual’s own judgment of his or her level of functioning. Feelings of worthlessness and of having lost the joy of living are common. Wild weeping may occur as a general reaction to frustration or anger. Such crying spells do not seem to be directly correlated with a specific function. Example: It’s hard to describe the state I was in several months ago. The depression was total – it was as if everything that happened to me passed through this filter which colored all experiences. Nothing was exciting to me. I felt I was no good, completely worthless, and deserving or nothing. The people who tried to cheer me up were just living in a different world. †¢Cognitive symptoms: Besides general feelings of futility, emptiness, and hopelessness, certain thoughts (e. g. egative view of the self, of the outside world and of the future [Beck, 1974]) and ideas are clearly related to depressive reactions. Disinterest, decreased energy and loss of motivation make it difficult for the depressed person to cope with everyday situations. Work responsibilities become monumental tasks and the person avoids them. Self-accusations of incompetence and general self-denigration are common. Other symptoms include difficulty in concentrating and in making decisions. †¢Behavioral symptoms: Shows social withdrawal and lowered work productivity. Other symptoms include sloppy or dirty clothing, unkempt hair, and lack of concern of personal hygiene. Slowing down of all body movements, expressive gestures and spontaneous responses is called psychomotor retardation. †¢Physiological symptoms: Loss of appetite and weight Constipation -Sleep Disturbance, e. g: insomnia, nightmares hypersomnia -Disruption of the normal menstrual cycle -Aversion to sexual activity Symptoms of Mania †¢Affective Symptoms: The person’s mood is elevated, expansive, or irritable. Show boundless, energy, enthusiasm and self-assertion. If frustrated, they may become profane and quite belligerent. †¢Cognitive symptoms: flightiness, pressured thoughts, lack of focus and attention, and poor judgment. Although much of what they say is understandable to others, the accelerated and disjointed nature of their speech makes it difficult to follow their train of thought. They seem incapable of controlling their attention, as though they are constantly distracted by new and more exciting thoughts and ideas. †¢Behavioral Symptoms: Uninhibited, engaging impulsively in sexual activity or abusive discourse. DSM-IV-TR recognizes 2 levels of manic intensity:- Hypomania: affected people seem to be ‘high’ in mood and overactive in behavior. Their judgment is usually poor, although delusions are rare. When they interact with others, people with hypomania dominate the conversation and are often grandiose (meant to produce an imposing effect) . Mania: more disruptive behaviors, including pronounced over activity, grandiosity and irritability. Their speech may be incoherent and they do not tolerate criticisms or restraints imposed by others. Hallucinations and delusions may appear. †¢Physiological Symptoms: decreased need for sleep, accompanied by high levels of arousal. The energy and excitement these patients show may cause them to lose weight or to go without sleep for long periods. UNIPOLAR DISORDERS Depression without a history of mania In almost all countries, women are at least twice as likely as men to experience episodes of severe unipolar depression. Approximately half of people with unipolar depression recover within six weeks and 90% recover within a year, some without treatment (Kessler, 2002; Kendler et al. , 1997). However, most of them have at least one other episode of depression later on their lives (Boland Keller, 2002). People become depressed when the daylight hours are short and recover when the daylight hours are long. A person’s mood changes cannot be the result of psychosocial events, such as regularly being unemployed during the winter. Rather, the mood changes must seem to come on without reason or cause. *Dsythmia Differs from major depression in terms of both severity and duration. Dsythmia represents a chronic mild depressive condition that has been present for many years. In order to fulfill DSM-IV-TR criteria for this disorder, the person must, over a period of at least 2 years, exhibit a epressed mood for most of the day on more days than not. These symptoms must not be absent for more than 2 months at a time during the 2-year period. If at any time during the initial 2 years the person met criteria for a major depressive episode, the diagnosis would be major depression rather than dsythmia. As in the case of major depression disorder, the presence of a manic episode would rule o ut a diagnosis of dsythmia. When dysthymic disorder leads to major depressive disorder, the sequence is called double depression (Boland Keller, 2002). The distinction between major depressive disorder and dsythmia is somewhat artificial because both of sets of symptoms are frequently seen in the same person. In such cases, rather than thinking of them as separate disorders, it is more appropriate to consider them as two aspects of the same disorder, which waxes and wanes over time. Some experts have argued that chronic depression is a single, broadly conceived disorder that can be expressed in many different combinations of symptoms over time (McCullough et al. , 2003). BIPOLAR DISORDER A disorder marked by alternating or intermixed periods of mania and depression People with a bipolar disorder experience both the lows of depression and the highs of mania. Many describe their life as an emotional roller coaster. They shift back and forth between extreme moods. The essential feature of bipolar disorders is the occurrence of one or more manic or hypomanic episodes; the term bipolar is used because the disorders are usually accompanie d by one or more depressive episodes. Bipolar disorders include subcategories which describe the nature of the disorder; Bipolar I and Bipolar II. Bipolar I (Formally known as manic depression) where normal mood is interrupted by manic and major depressive episodes, or, occasionally, by what are referred to as mixed episodes in which manic and major depressive symptoms are both present. †¢Single manic episode- Presence of only one manic episode and no past major depressive episodes. †¢hypomanic- in a hypomanic episode, with at least one previous manic episode. †¢Manic- in a manic episode, with at least one previous major depressive, hypomanic, or manic episode. †¢mixed- in a mixed episode(i. e. or everyday during at least a one-week period, the criteria for a major depressive episode-except for duration-and a manic episode have both been met) †¢Depressed- in a major depressive episode, with at least one previous manic episode. †¢Unspecified- meets criteria for manic, hypomanic, or major depressive episode except for duration (i. e. the episode does not last long enough to meet the criteria for each ): at least one previous manic episode. Bipolar II This is similar to bipolar I except that hypomanic episodes occur instead of manic episodes. The distinction between the two disorders was clarified in the DSM-IV. †¢Recurrent major depressive episodes with hypomania- one or more major depressive episodes and presence of at least one hypomanic episode: never has a manic episode. Cyclothymic Disorder Manic and depressed moods that are chronic and relatively continual in nature. Depressive (Unipolar)Bipolar Disorders Low incidence of manic disturbances -the late twenties -low tendency to attempt suicide, anxiety -lithium has little effect- higher incidence of manic disturbances -Age of onset is earlier (the early twenties) Display psychomotor retardation a greater tendency to attempt suicide -respond to lithium Causes †¢Genetic Factors Family, twin and adoption studies suggest the involvement of genetic factors. The prevalence of depression in the random population (10% for men and 20% for women) is the baseline against which the concordance rates can be compared. -Family pedigree studies select people with unipola r depression as probands(the person who is the focus of a study), examine their relatives, and see whether depression also afflicts other members of the family. If a predisposition to unipolar depression is inherited, a proband’s relatives should have a higher rate of depression than the population at large. -One of twin studies looked at nearly 200 pairs of twins. When a monozygotic twin had unipolar depression, there was a 46% chance that the other twin would have the same disorder. In contract, when a dizygotic twin had unipolar depression, the other twin had only 20% chance of developing the disorder. (McGuffin et al. ,1996). -One study looked at the families of adopted persons who had been hospitalized for this disorder in Denmark. The biological parents of these adoptees turned out to have a higher incidence of severe depression than did the biological parents of a control group of nondepressed adoptees. (Wender et al. ,1986) Evaluation 1. Nature vs. Nuture It is difficult to separate out the influence of nature and nurture. Whilst the twin studies provide strong evidence for the role of genetic factors and the adoption studies point to the role of nature over nurture this is not conclusive. 2. Diathesis-stress model Genes alone do not determine who will develop depression – they only create vulnerability. Thus, they are not a direct cause as other factors must trigger the disorder. Evidence for this is that the concordance rates are not 100%, which shows that depression is due to an interaction of genetic and other factors. †¢Biochemical Factors The monoamine hypothesis suggests that depression is due to abnormal levels of neurotransmitters in the monoamine group. This was expanded upon the permissive anime theory (Kety,1975), which proposes that the level of noradrenaline and dopamine are controlled by serotonin. When serotonin is low the levels of noradrenaline fluctuate wildly; low levels are associated with depression and high levels with mania. The low levels of serotonin may be genetically inherited. The three neurotransmitters – serotonin, dopamine and noradrenaline – are part of the monoamine group and play a role in normal arousal and mood. By-product compounds of the enzymes that act upon noradrenaline and serotonin were lower than normal in the urine of depressives. (Teuting, Rosen Hirschfeld, 1981) Antidepressant drugs such as the monoamine oxidase inhibitors (MAOIs) increase the levels of noradrenaline and serotonin and alleviate the symptoms of drepssion, which supports the influence of the biochemical on mood. -Post-mortem studies of patients who committed suicide show reduced levels of serotonin and an increased number of serotonin receptor sites. Evaluation 1. Cause, effect or correlate It is difficult to establish whether the low levels of neurotransmitters c ause depression, are an effect of having the disorder or are merely associated. Causation cannot be inferred as associations only have been identified. 2. Treatment aetiology fallacy The success of antidepressant drugs as a treatment does not necessarily mean the biochemical are the cause of the depression in the first place. MacLeod (1998) described this as the treatment aetiology fallacy and used headaches as an example. Aspirin works well as a treatment but this doesn’t mean the headache was due to an absence of aspirin. 3. Reductionist and deterministic Biological explanations are reductionist as they focus on only one factor and t present our understanding of biochemistry is oversimplified. This means other biological factors, such as hormones and psychological factors are ignored. The biological explanations are also deterministic because they ignore the individual’s ability to control their own behavior. †¢Psychodynamic Factors According to Freud, we are victims of our feelings, as repression and displacement are defense mechanisms in r esponse to actual loss ( death of a loved one) and symbolic loss (loss of status) that enable us to cope with the emotional turmoil, but can result in depression. Individuals with excessive dependence on others for self-esteem as a consequence of oral fixation are particularly vulnerable and unable to cope with loss. Anger at the loss is displaced onto the self, which affects self-esteem and causes the individual to re-experience loss that occurred in childhood. Freud believed that superego (or conscience) is dominat in the depressed person and this explains the excessive guilt experienced by many depressives. In contrast, the manic phase occurs when the individual’s ego, or rational mind, asserts itself and s/he feels in control. However, early loss does not consistently predict depression. Evaluation 1. Although the findings indicate that losses and inadequate parenting sometimes relate to depression, they do not establish that such factors are typically responsible for the disorder. In the studies of young children and young monkeys, for example, only some of the subjects who were separated from their mothers showed depressive reactions. 2. Many findings are inconsistent. Though some studies find evidence of a relationship between childhood loss and later depression, others do not. (Parker,1992; Owen, Lancee Freeman, 1986) 3. Certain features of the psychodynamic explanation are nearly impossible to test. Because symbolic loss, fixation at the oral stage, and introjection are said to operate at an unconscious level, it is difficult for researchers to determine if and when they are occurring. Similarly, other psychodynamic ideas can be measured only by retrospective self-reports of people who are or have been depressed. †¢Behavioral Factors depression is due to maladaptive learning. The principles of operant conditioning have been applied to explain depression using reinforcement and punishment. Many behaviorists view depression as a product of inadequate or insufficient reinforcers in a person’s life, leading to a reduced frequency of behavior that previously was positively reinforced. oThe number of events and activities that are potentially reinforcing to the person. This number depends very much on individual differences and varies with the biological traits and experiential history of the person. For example, age, gender, or physical attributes may determine the availability of reinforcers. Handsome people are more likely to receive positive attention than are nondescript people. Young people are likely to have more social interaction than retirees are. A task-oriented person who values intellectual pursuits may not respond to interpersonal or affiliative forms of reinforcement as readily as other people would. To such a person, a compliment such as ‘I like you’ may be less effective than ‘I see you as an extremely competent person. ’ oThe availability of reinforcements in the environment, Harsh environments, such as regimented institutions or remote isolated places, reduce reinforcements. oThe instrumental behavior of the individual. People in depression lack social behaviors that can elicit positive reinforcements. They feel more uncomfortable in social situations and the elicit depression in others. They tend to talk about themselves (more so than other people do) without being asked to do so. By creating conditions that further their depression or drive others away, these individuals thereby lose any social reinforcement that others could provide. Evaluation 1. Reductionist The behavioral explanations are greatly oversimplified as they focus on only one factor, the environment. This focus on the external means internal factors that may bee more influential, such as biological and cognitive are ignored. 2. Environmentally deterministic The behavioral explanations are deterministic as they suggest that behavior is controlled by the environment, which ignores the individual’s ability to control their own behavior. 3. Ignore nature The behavioral explanations overemphasize nurture and ignore nature. 4. Population validity Learned helplessness are an explanation of the development of depression may be more relevant to certain types of people, e. . those who lack social skills and so have limited emotional support. †¢Cognitive Factors 1. Arbitrary inference- The person with depression tends to draw conclusions that are not supported by evidence. For example, a woman may conclude that ‘people dislike me’ just because no one speaks to her on the bus or in the class. A man who invites a woman to dinner and finds the restaurant closed that ev ening may see this as evidence of his own unworthiness. In both cases, the person draws erroneous conclusions from the available evidence. People with depression are apparently unwilling or unable to see other, more probable, explanations. 2. Selected Abstraction- The individual takes a minor incident or detail out of context and focuses on it, and these incidents tend to be trivia. A person corrected for a minor aspect of his work may take the correction sign of incompetence or inadequacy – even when the supervisor’s overall feedback is highly positive. 3. Overgeneralization- The individual tends to draw a sweeping conclusion about his ability, performance or worth from one single experience or incident. The comments of a student seen by one of the authors at a university psychology clinic provide another illustration of overgeneralization: when he missed breakfast at the dormitory because his alarm clock didn’t ring, the student concluded, ‘I don’t deserve my own body because I don’t take care of it. ’ Later, when he showed up late for class through no fault of his own, he thought, ‘ what a miserable excuse for a student I am. ’ When a former classmate passed by and smiled, he thought, ‘I must look awful today or she won’t be laughing at me. ’ 4. Magnification and minimization- The individual tends to exaggerate limitations and difficulties and play down accomplishments, achievements and capabilities. Asked to evaluate personal strengths and weaknesses, the person lists many shortcomings or unsuccessful efforts but finds it almost impossible to name any achievements. Evaluation 1. Causes or effect? The evidence is not convincing that negative cognitions precede the disorder but nor has this been disproved. Therefore, conclusions are limited. It may be that the relationship is curvilinear, . i. e. negative thinking predisposes depression and depression increases negative thinking, 2. Descriptive not explanatory. The research may describe the nature of depressives’ thoughts rather than explain the development of depression if negative cognition is a consequence, not a cause, of depression. If it is a cause then it is not clear what causes the negative cognitions in the first place. 3. Success of cognitive treatments. Cognitive behavioral therapy (CBT) has been found to be as effective as antidepressants (Elkin at al. , 1985), which supports the role of cognitive factors in depression. But the cure does not necessarily indicate the cause, as the treatment aetiology fallacy states. 4. Lack of reliability. The prospective research is inconsistent and so we cannot be sure if negative cognitions cause or are a consequence of depression. Treatments for Depressive Disorders 1. Medication 4 kinds of antidepressant medication: tricyclic antidepressants (TCAs) Heterocyclic antidepressants (HCAs) Monoamine oxidase inhibitors (MAOIs) Selective serotonin reuptake inhibitors (SSRIs) Each medication is designed to heighten the level of a target neurotransmitter at the neuronal synapse. This heightening can be accomplished by: boosting the neurotransmitter’s synthesis blocking its degradation preventing its reuptake from the synapse, or Mimicking its binding to postsynaptic receptors 2. Electroconvulsive Therapy Electroconvulsive Therapy (ECT) is generally reserved for patients with severe unipolar depression who have not responded to antidepressant medications. It consists of applying a moderate electrical voltage to the person’s brain for up to half a se cond. The patient’s response to the voltage is a convulsion (seizure) lasting thirty to forty seconds, followed by a five- to thirty- minute coma. Most patients with serious depression show at least a temporary improvement after about 4 ECT treatments (R. Campbell,1981). The ECT mechanism is not fully understood; it may operate on neurotransmitters at the synapses, as do antidepressants. One major advantage of ECT is that the response to treatment is relatively fast (Gangadhar, Kapur Kalyanasundaram, 1982). However, common side effects include headaches, confusion and memory loss. Many clinicians believe that ECT is the most rapid and effective treatment for major depressive episodes. ECT is controversial and critics have urged that it be banned as form of treatment. 3. Psychotherapy and Behavioral Treatments Because the use of antidepressant medication or ECT involves a number of disadvantages, clinicians have sought other approaches to either supplement or replace medical treatment of depression. A variety of psychological forms of treatment have been used, such as psychoanalysis, behavior therapy, group psychotherapy and family therapies – all with some success. -Interpersonal Therapy is a short term, psychodynamic-eclectic type of treatment for depression. It targets the client’s interpersonal relationships and uses strategies found in psychodynamic, cognitive-behavioral and other forms of therapy. Clients gain insight into conflicts in social relationships and strive to change these relationships. For example, by improving communications with others, by identifying role conflicts and by increasing social skills, clients are able to find relationships more satisfying and pleasant. Although interpersonal psychodynamic resembles psychoanalysis and psychodynamic approaches in acknowledging the role of early life experiences and traumas, it is oriented primarily toward present, not past, relationships. Cognitive-Behavioral Therapy combines cognitive and behavioral strategies. The cognitive component involves teaching the patient the following:- a. to identify negative, self-critical thoughts (cognitions that occurs automatically) b. to note the connection between negative thoughts and the resulting depression. c. to carefully examine each negative thought and decide whether it can be supported d. to try to replace distorted negative thoughts with realistic interpretations of each situation At the outset of the cognitive therapy, the client is usually asked to begin monitoring his or her negative thoughts and list them on a chart. It is important for the client to include all thought and emotions associated with each distressing event that takes place each day. The second part of the cognitive-behavioral approach is behavior therapy, which is usually indicated in cases of severe depression in which the patient is virtually inactive. One primary assumption underlying this approach is that the patient is not doing enough pleasant, rewarding activities. During depression, people tend to belittle themselves and to withdraw from others; they can interpret their self-imposed social isolation as sign of being unpopular and inadequate. To address this problem, the therapist asks the patient to keep a daily activity schedule, listing life events hour by hour and rating the ‘pleasantness’ of each event. Once the client becomes more active, the therapist may ask the person to attend a social skills training program. Improvements in social skills generally help clients become more socially involved and can make that involvement rewarding. Treatments for Bipolar Disorders Although the forms of psychotherapy and behavior therapy used for depressive disorders are also used for bipolar disorders (e. g. MAOIs and SSRIs), drugs (especially lithium) are typically given to bipolar clients. Lithium is used as a mood-stabilizing drug to prevent or reduce future episodes of bipolar disorder. As noted, the manic phase of bipolar disorder may be caused by too much neurotransmitter (primarily norepinephrine) at brain synapses or by neurotransmitter dysfunction. Lithium decreases the total level of neurotransmitters in the synaptic areas by increasing the reuptake of norepinephrine into the nerve cells. Accurate measurements of lithium blood levels are easily obtained and dosages can be adjusted accordingly. Summary Severe depression is a major component of the mood disorders; it involves affective, cognitive, behavioral, and physiological symptoms, such as sadness, pessimism, low energy and sleep disturbances.

Use of Characterization in Miguel Street Essay Example

Use of Characterization in Miguel Street Paper The authors Vidiadhar Surajprasad Naipaul, commonly known as V. S Naipaul was born in Trinidad, on 17th of August 1932. His family descended from immigrants from north of India. His grandfather worked in a sugar cane plantation and his father was a journalist and a writer. He was educated at Queens Royal College and after winning a government scholarship, he went on to study in England at University College in Oxford from where he achieved his Bachelor of Arts degree. Apart from a few years in the middle of 1950s when he was employed by BBC as a free-lance journalist, he has devoted himself entirely to his writing. His works consist mainly of novels and short-stories, but some are also documentaries. In the beginning he found himself rootless, as he felt alienated from his background but he found his voice as a writer in the mid 1950s, when he started to examine his own Trinidadian background. Most of his novels revolve around the Trinidadian society and Miguel Street is one of them which came out in 1959. Miguel Street has been classified as a group of short stories, as a series of sketches and as a novel. It is considered as a novel because of the fact that it is unified by a single narrator and by several patterns and themes.

Furthermore those major characters reappear as minor characters in other chapters. Characterization is a key factor in understanding Naipaulss Miguel Street and V. S Naipaul reveals its characters in a certain way. He uses conflict to reveal a character to the reader and the other characters in the novel. Most of the characters in the book are controversial and each character has an element of conflict. The readers learn about a character through the conflict they are facing and the way that character faces its conflict. It is conflict through which the nature of the character is revealed and the way that character thinks when faced with different problems. V. S Naipaul has used a narrator boy through whose eyes we see other characters. The narrator is a young boy in his adolescence whose observation of the people of the street also reflects his unconscious awakening as he grows from childhood through boyhood to early manhood. His growing up process is reflected in the unmasking of the characters who are each introduced initially as mysterious, romantic or colorful personalities who win the admiration of the people of the street until they are gradually exposed to emerge in their true colors. They are forced to emerge in their true colors when their conflict is revealed. V. S Naipaul uses the narrator boy and the gang to a certain extent to bring each of the characters one by one under a microscope where they are examined in detail. First the readers are given a fake image of the character because the character lies about his real identity and hides the conflict or the problem they are facing. But as soon as the conflict is revealed to the readers and the other characters in the novel, they all get to see the real side of the character. It is not only his peculiarities which are revealed but also their frustrations in life and their gradual decline from high expectations to an acceptance of failure, resignation to it or resorting to escape from the street. Bogart Bogart is the first character that the readers are introduced to. He has no identity and it is ironic how his mysteriousness is accepted unquestioningly by the people of Miguel Street. No one really knows about Bogart, not even his real name. He was first named Patience just because he plays a cards game called Patience all day and then he is given the name Bogart because of his resemblance to an actor in a movie called Casablanca. He comes to Miguel Street from somewhere and becomes the most popular man in the street at one point as the narrator boy says on page 11 He was at one time quite the most popular man in the street. Bogart creates a fake identity of himself in Miguel Street and never tells anyone about his real story, about his problem or conflict that he is facing. In fact he goes way out of his real life into fantasy which is apparent when he explains where he had disappeared to, on page 14 He had got a job on a ship and had gone to British Guiana. There he had deserted, and gone into the interior. He became a cowboy on the Rupununi, smuggled things into Brazil, and had gathered some girls from Brazil and taken them to Goergetown. He was running the best brothel in the town when the police treacherously took his bribes and arrested him. So he creates this fake identity of himself. However everything is revealed altogether when he is arrested under the charge of bigamy. He had left his first wife in Tunapuna because they could not have any children which questioned his manhood. So to avoid reality he ran away and came to Miguel Street. Then after some time he goes away and makes a baby with a Caroni Girl, Bogart still returns to Miguel Street to be a man as Hat explains at the end. POPO Popo story is quiet similar to Bogarts. He is also at first seen as a happy person. He also creates a fake identity of himself for self-amusement. He calls himself a carpenter and pretends to be busy building a thing without a name. He doesnt do anything for living and depends entirely on his wife who is employed as a cook. He shows off his prosperity in life and his status as a carpenter. He stands in the sun every morning with a glass of rum which he doesnt drink, he just holds it and when someone passes by he dips his fingers and licks them and waves at the person which shows that he is just showing off and enjoys himself being envied by other characters in the Miguel Street. However, when his conflict comes up the readers and the other characters in Miguel Street get to see a new character of Popo. His wife suddenly runs away with a gardener in her workplace and it is after that a change in Popos life-style is seen. It is also from there the readers and the other characters learn about Popo. He is no longer a man to be envied and then he disappears from Miguel Street just like Bogart and beats the guy with whom his wife had run away. He comes back to Miguel Street as a completely changed man. He starts working day and night at his carpentry and is no longer making the thing without a name. He even paints his house a bright green and red as though to express his new-found character. Eventually, his wife returns, takes up her old employment and Popo reverts to the old life of making the thing without a name.

What is the Purpose of Environmental Law Essays

What is the Purpose of Environmental Law Essays What is the Purpose of Environmental Law Paper What is the Purpose of Environmental Law Paper Significant developments in environmental law can be traced back to the 1800s; and dealt largely with public health concerns initially. [1]Only since the 1970s however, has ‘environmental law’ as a separate concept formed to tackle the objective of ‘sustainable development’. [2]Common law too has played an equally vital part in between these developments. [3]Indeed, the purpose of environmental laws from 1800s to present has shifted. [4]This shift in purpose shall be discussed, but firstly, taking into considerations the definitions of ‘purpose’,[5] ‘environment’,[6] and‘law’[7] ; the question shall be interpreted to ask – what the intention of the values are in law and policy,concerning the air, land, and water. Victorianenvironmental law reflected very muchthe concerns of ‘nuisances’[8] to public health. Industrialisation only accentuated these concerns within popular values and provisions were taken to intentionally rid the people of such ‘nuisance’. An early example of this creeping concern is the Factories Act 1833. [9]Victorians had mere appreciation of‘nuisance’. What would be considered as pollution in modern perspective was seen as an indicator of prosperity in Victorian Britain. [10] Nevertheless, public health concerns materialised in environmental ‘nuisance’ law. To illustrate, the Smoke Abatement (Metropolitan) Act 1853[11]provided for the control of the nuisances from smokes and vapours in the air – dangerous to human health. Similarly, the Alkali Act 1863[12] intended to place regulation on the condensing of corrosive Muriatic Acid in Alkali Factories – dangerous to public health; so as to limit its ‘nuisance’ to the public. Therefore, Victorian environmental law, despite being slow to recognise environmental significance, intended to limit the damage of these ‘nuisances’; more to the public that to the environment per se. Later, in common law, ‘mere nuisance’ transformed to actual concern for the environment itself. There was a change of opinion from tackling pollution that was already present, to trying to prevent the emergence of any new sources in the first place. As an example,the English Law, House of Lords case Rylands v Fletcher[13]will be examined. In this case it was established that if a man’s nuisances spread to another’s land, he would be strictly liable for the damage caused to the others land. Thus, these preventative measures established precedent to control citizens from creating new pollution through fear of civil action. In addition to this,the later House of Lords case of Hunter v Canary Wharf Limited[14] followed the ‘Rylands rule’ in that ‘nuisance’ (or pollution) would have legal causation to land damage only. Apparently so, this controlling intention in common law protected the environment from damage but was perhaps somewhat unfair to the private citizen in some cases. To illustrate this, if a man had suffered loss as a result of harm caused by another nuisance he would be unlikely to receive damages for example his property as in Canadian High Court case of Bottoni v Henderson. [15]Later, statutory reform wouldbe needed to proportionate and protect both environmental, as well as private interest. [16] Therefore, the purpose of environmental law developed to protective the environment more than the public as it once did in the past; despite perhaps being disproportionate in some circumstances. In post-war Britain this intention to protect the environmentcontinues[17]but, particularly after 1972 toward the principle of ‘sustainable development’;as defined by the Bruntland Report of 1987. [18] It is arguably the main purpose of environmental law today. [19]Perhaps an unsubstantiated claim, it has been argued that the principle in fact ‘†¦plac[es] human†¦ interests above†¦ environmental protection’;[20]overlooking that it intends tolimit the impact of human population on world ecosystems. [21] The Brundtland report has been criticised to say that its breadth is difficult to be incorporated into policy. [22]This is apparent in the UK up until around the mid 1990s. [23] Despite this, there has been significant intention to incorporate sustainable development; the Climate Change (Scotland) Act 2009 has done particularly well at this. [24] However, it should be asked how effective our sustainability policy really is. The Sustainable Development Commission – the policy advisor for the UK and Scottish Government is to be shut down. [25]Furthermore, this closure has been openly criticised by its commissioners. [26] The intention therefore of environmental law in modern Britain is to pursue sustainable development; all be it not realised yet in policy. In conclusion, the purpose of environmental law was once public protection, manifested by popular concern, gradually achieved through statue. In addition, later common law provided a good effort to purpose pollution prevention. Now, from international cooperation it now pursues sustainable development, if somewhat ineffective at doing so.

Marketing strategy (bringing StarBuck to Trinidad and Tobago) Research Paper

Marketing strategy (bringing StarBuck to Trinidad and Tobago) - Research Paper Example Starbucks has successfully created its position as the best place for socializing other than office and home. The only way to enter the new markets is to implement the same global marketing strategy that it has been following for each of its expansion plan. Hence, it should slowly enter the markets of Trinidad and Tobago so that the customers in the region accept the concept of specialty coffee shops and enjoy the amazing ambiance of the outlet. ... The primary aim of Starbucks is to establish itself as â€Å"a highly respected and recognized brand in the international market† (Starbucks, 2012). Situational Analysis of Starbucks Current Marketing strategy After careful analysis of the marketing strategies highlighted by Michael Porter, cited by Alison (2010), Starbucks is following a differentiation strategy. Initially, the main element of its business activities was to focus on particular aspects with strong emphasis on creating differentiated products within the target consumer market. However, the company soon realized that it needs to strengthen its position in the market by developing a differentiation strategy and the success of Starbucks is evident from the fact that it has developed an excellent marketing mix for its customers. In order to expand its operations in the international market, it is offering same â€Å"coffee experience† to the international customers by providing them premium quality products and aesthetically designed ambiance (Tu, Wang & Chang, 2012). It has ensured that there is uniformity in its marketing activities by using only third party mediums for promoting its product and service offerings. According to Michelli (2007), Starbucks has allocated only 4% of its total cost on the advertising budget. One of the key elements of differentiation strategy is to introduce new and innovative products in the market and Starbucks has been exceeding its customers’ expectations by offering them products that are totally different from existing ones (Parayani, 2011). The innovation element of its marketing strategy gives it a competitive edge in the specialty coffee industry. In order to ensure that it develops entirely new offerings, a huge amount of money is invested in

Equity and trusts Case Study Example | Topics and Well Written Essays - 2000 words

Equity and trusts - Case Study Example As was stated in Knight v Knight2 by Lord Langdale MR, there are three certainties that must be present in order to constitute a valid express trust, they are certainty of words, certainty of subject matter and certainty of objects.3 The certainty of words requirement was described in Re Kayford Ltd.4 as being akin to a certainty of intention. The intention is to impose a mandatory obligation on the trustees of how the trust property is to be dealt with. As was stated in Banks v Goodfellow5 the testator does not need to have the understanding of a lawyer as to the contents of the document but a clear intention to trust, must be present. The certainty of subject matter relates to the trust property. The trust property must be clearly defined and identified. Otherwise the trust must fail as who is to decide which assets are to form the basis of the trust. The case law has established that uncertainty as to the subject matter can either be conceptual or evidential. By conceptual uncertainty is meant that it is impossible to ascertain what the intention of the testator was. For example, in Palmer v Simmonds6 Kindersley V-C said that a trust could not be created, as a 'definite, clear and certain part' of the estate had not been identified. The court is willing to exert effort in ascertaining the trust property as Ungoed-Thomas did in Re Golay7 where he found that a 'reasonable income' was capable of ascertainment by the court, but if there is no clear property, there can be no trust. What's more, the allocation of property must be specific. In Hemmens v Wilson Browne (a firm)8 it was held that a right to payment of 110,000 at any time could not form a trust as the sum was unspecific, or in the words of Judge Moseley QC, 'there was no identifiable fund to which any trust could attach.'9 I think it is fair to say that 'my houses' is sufficiently specific to allow for ascertainment. To my stepdaughter Analise the home of my parents with instructions that the property is held within the family in perpetuity. This provision raises two concerns. The first is that there is a good chance that Lady Penelope does not presently own the house of her parents. While there are tax and other reasons why she may own it, we are informed that her parents were still alive at the time of her death. If Lady Penelope does not presently own the house of her parents, then it is impossible for her to create a valid trust over it. While she may have been due to inherit the house, we are told that her parents are still alive and this would therefore not occur. It is a fact of law that it is not possible to create a trust for property that the testator does not own yet, but hopes to own in the future. This has been expressly stated in the case of future inheritance under a will or intestacy.10 In Re Ellenborough11 the settlor granted in 1893 to trustees, any property she may become entitled to in the future on the deaths of her brother or sister. When her brother died nine years later, she decided not to give the property to the trustees, and Buckley J upheld her decision on the ground that no trust could have been created in 1893 over property that the

Rate of reaction Essay Example for Free

Rate of reaction Essay Apart from these few improvements I think the equipment and the method I used was an appropriate way of investigating how concentration effects the rate of reaction on an enzyme. A variable that I could try for an extra experiment is temperature. I could try increasing the temperature of the catalase to see if increasing the temperature has the same effect on an enzyme as it does with concentration. This would help me to see which variable, temperature or concentration has a greater effect on the volume of oxygen produced from the reaction of an enzyme. I am going to work out the rate of reaction from the average value of each of the concentrations of hydrogen peroxide. I will work out the rate of reaction for every 10 second from the average values by using my graphs. Reaction Rate for the concentration of   Reaction Rate for the concentration of 6%  cm3/s From looking at these calculations I can say that for all the concentrations of hydrogen peroxide the reaction rate was fastest at the start of the reaction. During the reaction the rate decreased and eventually the reaction stopped. I can explain this by using the lock and key model. This occurs because the catalase is breaking the particles of the hydrogen peroxide to form into oxygen. This causes the hydrogen peroxide to get used up as the catalyst can alter the rate of reaction without getting used up. This then leaves the catalase to react with no substance. Data Logging Data logging is another experiment I did to extend my experiment. I looked at the enzyme activity experiment in a different way. This time I used the same quantity of catalase and hydrogen peroxide but instead of measuring the volume of oxygen produced, I found out the temperature increase for each of the different concentrations of hydrogen peroxide. Method 1. Collect all equipment and set the experiment up 2. Wear safety glasses as you are using chemicals 3. Pour 25cm3 of each concentration of hydrogen peroxide into a measuring cylinder 4. Pour each concentration of hydrogen peroxide into three different polystyrene cups 5. Measure 1mm of catalase into three different syringes 6. Make sure that the end of the probe is touching the bottom of the cup and that the hydrogen peroxide is completely covering it 7. Inject all three of the catalase at the same time into each polystyrene cup 8. At the same time start the computer as you inject the catalase, to start of the measurement of the temperature, of the hydrogen peroxide 9. Watch how the computer measures the temperature for 2minutes as it transfers all the information into a graph 10. Stop the graph at 2 minutes and print out the results Conclusion From my results I can see that the 6% concentration of hydrogen peroxide has given of the highest temperature. This is because the concentration of 6% has many particles of hydrogen peroxide which will have a greater chance of colliding with the catalase. The concentration of 1. 5% and 3% has given of less heat causing a lower temperature. This is because they have less particles of hydrogen peroxide to collide with the enzymes. This result can be explained by the kinetic and collision theory. The increase in heat gave an increase in the kinetic energy. This means that there would be more collision between the hydrogen peroxide particles and the catalase, which would lead to a better chance of collision being successful. This experiment is related to my first experiment as the increase in concentration gave off more oxygen which gave us an increase in temperature. I found out that the 6% concentration gave of the most oxygen which causes a rise in temperature and the 1. 5% gave of the least oxygen causing a lower temperature. The 6% also gave off the most oxygen in the shortest time whereas the 1. 5% concentration gave off the least oxygen in the longest time. From looking at my graph I can see that the 6% concentration had the steepest slope which if I relate back to my rates of reaction theory. I can say that the steeper the slope the faster the reaction. The 1. 5% concentration had the smallest gradient which means it had the slowest rate of reaction. Overall this proves my original prediction, that the 6% concentration of hydrogen peroxide has the fastest rate of reaction and the 1. 5% concentration has the slowest. Reaction Rates During a reaction, reactants are being used up and products are forming. The reaction rate tells us how fast the reaction is taking place. You can calculate the reaction rate by measuring how much reactant is used up or how much product forms in a given time. Reaction rate = change in amount of a substance time taken The reaction rate can also be calculated by using a graph. The slope of the graph tells us how quickly the reaction is happening. The steeper the slope, the faster the reaction Results from the Trial Experiment Time (s) Volume of O2 evolved (cm3) 1. 5% Volume of O2 evolved (cm3) 3% Volume of O2 evolved (cm3) 6% Average I did a trial experiment to help me understand the experiment. The trial experiment showed me how quickly each concentration of hydrogen peroxide produced the amount of oxygen gas in one minute. I also learnt that slow pressure is needed with the small gas syringe because too much pressure causes the catalase to spill out.
