Computer Monitors essays

Computer Monitors essays The most used output device on a computer is the monitor. The display provides instant feedback by showing text and graphic images. Most desktop computers use cathode ray tube displays. Portable computers use liquid crystal display (LCD). LCD monitors are now beginning to replace CRTs. This is due to a slimmer design and a use of less energy (How Stuff Works). IBM introduced the Color Graphics Adapter (CGA) in 1981. It was capable of rendering four colors. It had a maximum resolution of 320 pixels horizontally by 200 pixels vertically. In 1984 the Enhanced Graphics Adapter (EGA) was introduced. This allowed 16 different colors. Its resolution was increased to 640x350 pixels. This improved the appearance of the display (PC Tech). The Video Graphics Array (VGA) was introduced in 1987. VGA monitors are still in use today. This is a standard established to provide higher pixel addressability. The VGA consists of seven sub-systems, including: graphics controller, display memory, serializer, attribute controller, sequencer and CRT controller (PC Tech). The graphics controller can perform logical functions on data being written to display memory. Display memory is a bank of 256k DRAM divided into four 64k color planes. It is used to store screen display data (How Stuff Works). The serializer takes display data from the display mem ory and converts it to a serial bit stream which is sent to the attribute controller. The attribute controller contains the color look up table which determines what color will be displayed for a given pixel value in display memory (PC Tech). The Extended Graphics Array (XGA) came about in 1990. Its resolution in true color is 800x600 pixels, and 1024x768 in 65,536 colors (How Stuff Works). The size of your display is determined by aspect ratio and the screen size. Most displays use an aspect ratio of 4:3 (How Stuff Works). The projection surface of the display is called the screen...

Prison Life and Strategies to Decrease Recidivism Research Paper

Prison Life and Strategies to Decrease Recidivism - Research Paper Example One of the concerns that a person encounters upon entering prison is the lack of freedom to seek the health care provider one desires. The condition inside prison cells, such as congested spaces, limited movement, the mixture of cultures, etc. might have a toll upon the mental and physical health of an inmate. Thus, adequate health service must be provided inside the prison so that the health of the prisoner can be adequately managed. The Bureau of Prisons provides four levels of medical care to which inmates are assigned by the Designation and Sentence Computation Center (DSCC) based on the information gathered from the investigation report. Upon arrival at the facility, the provisional care for the inmate is reviewed by the prison clinicians. Non-provisional care is assigned depending on the needs of the inmate, which takes into consideration the ability to function without assistance from another (Ellis, 2008). Provision of medical care to inmates also varies depending sentence or status of the case. Thus, inmates whose sentence has not been read, those with the sentence below 12 months, or pre-trial inmates are not eligible to â€Å"medically appropriate-not always necessary† health service, â€Å"limited medical value,† as well as â€Å"extraordinary† service. Some categories of illnesses such as cancer, HIV, diabetes, etc. may also determine the type of care that may be given to the inmate.The medical services provided by the Bureau are determined by the following levels of medical intervention.

Strategy - Assignment Example 2) According to Wal-Mart, it needs substantial brands to form associations with it in order to attract affluent customers and also have a tendency of increasing peripheral business by selling other commodities. Therefore, forming associations with Levis’ allows it to attach a designer brand name with it that is accepted and received well in affluent customer’s segment. 3) Considering this case study, Wal-Mart has an edge over Levis’ in this corporate strategic alliance. This is so because Levis’ needs Wal-Mart for its business expansion as its own showrooms and other smaller retail networks have been proven incapable of attracting major customer base. Secondly, Levis’ has made considerable capital investment along with extensive business restructuring to suit Wal-Mart’s model. Therefore, Levis’ is dependent on Wal-Mart for cost-recovery and further business revival. Whereas Wal-Mart has a tendency of switching to other suppliers who wi ll offer better profit margins without incurring much liability. Therefore, Wal-Mart has a greater bargaining power as compared to Levis’. 4) Wal-Mart follows a broad target/ cost leadership generic strategy (Porter, 1980). It has multiple product lines that cater to every demographic segment. Furthermore, it has an extensive retail model with around 9000 stores worldwide. Such extensive network makes it a premium choice of suppliers due to which it has a greater bargaining power to persuade suppliers for providing their products at considerably low prices, as compared to other retail stores. 5) ‘Barriers to entry’ is an edge used by various leading market players to create obstacles for preventing new competitors from easily entering into market, industry or particular area (Sullivan & Sheffrin, 2003). Wal-Mart has developed a state of art automated system that is synched with its suppliers through point-of –sale mechanism. Therefore, the moment a product is bought, a supplier is notified which results into timely product delivery. As a result, customers prefer to stay with Wal-Mart since they know that their desired product will be available readily. This strong link with suppliers requires higher switching cost which is difficult to incur for its competition. As a result, their customers would also prefer Wal-Mart over them (Competing with information technology, n.d). 6) Value chain constitutes of following activities along with examples from Wal-Mart’s case study: Production- No self-production, acting as a retailer Production Management- Inventory management Quality Management- Extensive IT network and huge workforce Marketing & Sales- Sales teams dealing with suppliers General management- store management, venue management Marketing and sales management- Sales team heads dealing with suppliers in a particular industry Accounting and Finance- In-house finance department performing general accounting, forecasting etc. Res earch and development- Constant acquisition of market intelligence and tools to make IT its niche. Human Resource Management- Extensive handling of employees’ daily attendance, payroll, deployment etc (IMA, 1996). 7) Out of all the above mentioned activities, production management is the most important activity. Although Wal-Mart is a

Antebellum is defined at Dictionary.com as "Belonging to the period before a war, especially the American Civil War."1 In the Antebellum period in the South, many people owned slaves. In the south, plantations were "the most basic unit and the most vital element of the Southern antebellum economy."2 But at the heart of these plantations were the slaves. So vicariously, the slaves of the South were the most vital part of the Southern economy. Slaves, although taken from Africa, were still able to hold onto their religious traditions and beliefs. They would incorporate their traditions into the Christian belief structure that the south had already setup. They kept their dances, chants, songs, etc. by disguising them into their master's religion, thereby ensuring that it would be passed down from generation to generation. The slaves weren't treated as even close to equals to their masters. Their masters would live in the mansion of the plantation, while the slaves would dwell in recklessly built cabins that were separated from the rest of the plantation. These quarters were where the African American culture began to take shape. They began to be inspired to want what the white man wanted, and what they were denied. Slave labor was handed out by what each slave itself was capable of. If a slave were to finish a job early, he would be able to get the rest of the day off for recreational purposes. Not only that, but if a slave were to finish two jobs in one day, then he would receive the next day off. This day was commonly referred to as a "Holiday."

Carol Ann Duffy Notes

The poem closes with reminders of oppression, control and confinement. Possibility that was once limitless for the dolphins now has ‘limits' imposed upon it that will become impossible to bear. The realisation will probably hasten the creatures' death, signalling that there is as much at stake from a psychological perspective as there is from the physical circumstances. Stifling of natural impulse and behaviour can have fatal consequences. The ‘plastic toy' is a further reminder of the indignity visited on this majestic creature of the ocean. The phrase until the whistle blows is potentially ambiguous. In one level it simply refers to the controlling device used by the keeper but on another the poet might be reminding us that this sort of cruelty will continue until somebody exposes it for what it is. Duffy does effectively ‘blow the whistle' on such practices. The final line, with its reference to ‘our mind', neatly links the plural possessive pronoun with the singular noun ‘mind' indicating a collective voice for a species. The tense change to ‘we will' draws attention to the contrast between what the dolphins had, what they have now and can expect in the future. As a result, the dolphins assume an almost mythic status in that they appeal to archetypal impulses in us and in nature; they are not just the creatures who form part of it. ‘The Dolphins' may just as easily be read as a poem about human disillusion, betrayal and loss of direction as it is about animals. As an interpreter of experience it offers us a new language into which we would do well to translate ourselves. Foreign Duffy's preoccupation with language is dealt with here form the perspective of its cultural significance as much as its ability to say anything. To the immigrant, the country to which he or she has moved out of economic necessity will always be ‘foreign' but the indigenous population will regard them as foreigners. The fact that living in a foreign culture is something that is not easy to get used to is emphasised in the opening line of the poem. Despite living in a city for ‘twenty years' it remains ‘strange'. The immigrant is aware of his or her own ‘foreign accent' as it sounds to others. The strain of thinking in one language and having to translate into the speech of another cannot always be sustained and this is sensitively pointed out through the physical detail in the final stanza: ‘And in the delicatessen, from time to time, the coins / in your palm will not translate. ‘ The breakdown in communication in an everyday, exposed transactional situation is intensified through the words ‘Inarticulate' and ‘point'. Duffy's empathic feeling for such people is further expressed in her presentation of other actions such as ‘writing home', a way of maintaining contact with others of the same culture. The ‘local dialect' in the immigrant's ‘head' is coupled with the memory of his or her mother singing. These are details with which any sympathetic person might identify and throw into sharp relief the actual experience of seeing racist graffiti ‘sprayed in red' (line 12). Duffy's use of the simile, ‘Red like blood' to describe the paint is effective because of its monosyllabic directness of observation. It also resonates with a famous and terrible speech given by the Conservative politician Enoch Powell who, on 20th April 1968 warned that increased immigration into Britain would result in a ‘river of blood'. There is, then, a stark contrast between the uses of language as a sign system of cultural inclusion (stanza 2) and its deliberate use as a weapon of racial exclusion (stanza 3). The ‘hate name' of the racists is sprayed on a ‘brick wall' the harshness and unyielding nature of which is symbolic of the mentality of those who do such things. The unfamiliar, snowy weather and artificial ‘neon lights' create the impression for the immigrant that the country moved to is ‘coming to bits'. This image of fragmentation is, though, not entirely imaginary as he or she has a life splintered from all that is familiar and constantly experiences a sense of alienation. The italicised words at the close of the poem give voice to the immigrant but this only gives away a difficulty with English. The unfinished verbs, ‘Me not know' and ‘It like they only†¦' are drawn attention to by Duffy in order that the reader may ponder what it would be like to face the same language problem. The final words of the poem, ‘Imagine that' remind us of the opening and there is quite a clear impression that Duffy is adopting an undisguised didactic stance. As a skilled and empowered user of the English language herself she is drawing attention to the lot of those who are marginalised because of their deficiency in its use. Head of English The poet is introduced to the class by the Head of English who has very fixed views about what poetry should be. As in ‘Comprehensive', the school in question is a multi-ethnic institution. It is significant that the teacher should be dismissing the live woman poet because she does not conform to the Keatsean ideal in the teacher's mind. She is not dead and she is not male. How anyone with ‘English second language' is expected to relate to dead white English men is clearly a challenge laid down in the poem. The five six line stanzas are indicative of a controlled, contained environment, the institution and the teacher are reflected in this. Duffy does not choose to use rhyme throughout (as the teacher predicted) but reserves some obvious rhymes for the teacher to use. This is a very subtle use of a poetic technique to satirise someone who is complaining about its absence from modern poetry. So, simultaneously, Duffy is using a poetic technique to show that the teacher is wrong about it being absent from modern verse whilst showing that the rhyme, being obvious, is the sort needed by the teacher. The reference to Rudyard Kipling (1865-1936) is significant for a number of reasons. His poems do rhyme very regularly, and a number of them are redolent of British imperialism and nationalism in the Victorian period. This is actually grossly offensive in a multicultural context. ‘Winds of change' is a wittily ambiguous phrase since it refers to the words of Harold Macmillan, British Prime Minister 1957-63 speaking of political events such as the civil war in the Congo following the granting of independence from Belgium. It also tells us that the teacher is referring to flatulence, as well as reinforcing her own entrenched views. Duffy is ironically drawing attention to the fact that Calliope, ‘the Muse' and source of afflatus, breath of inspiration for poets is interrupted by an unwelcome allusion to noxious gases. The control possible in adopting a persona in the dramatic monologue is clear. Single word sentences, a hallmark of Duffy's verse, work very well in capturing the terse, rude attitude of the teacher. ‘Still. ‘ (stanza 2); ‘Right. ‘ (stanza 4); and ‘Well. Really. ‘ (stanza 5) show that she is singularly unimpressed by what she has heard. Here, it is what is implied by Duffy's economical use of language that is so effective in building an impression of what this woman is like. The idea of someone being in charge of an English Department who cannot see that it is she who actually has the ‘outside' view is worrying. The fact that she devotes a whole lesson to assonance also indicates the deadly boring teaching methods she employs. She obviously teaches technique out of context in the same way that she cannot accept modern poetry as belonging to a literary tradition. Like any poor English teacher she views tradition as something strictly to do with an unreachable past. It is striking that it is the silent space between the fifth and sixth stanzas that the poet has been allowed to read. Despite having encouraged pupils to ask questions ‘after all we're paying forty pounds', the teacher's response to the poet's reading is telling as she instructs the class to ‘run along'. The reader wonders just what ‘insight' the teacher has actually gained. Also, her pupils are unlikely to derive much from her teaching. More worrying, though, are the entrenched attitudes of a person who should not be in charge of the most expansive of subjects studied at school.

Mental Health Issues Are Treated Fairly By The Criminal...

This assignment will examine if individuals with mental health issues are treated fairly by the Criminal Justice System, taking into account the provisions of the Mental Health Act, the roles of professionals within it and the development of how people with mental health disorders are, and have historically been, viewed in society. Individuals with mental illnesses were initially segregated or incarcerated. The West has seen mental health views change as society has developed and medicine advanced. The first asylum dates back to the Bethlam Hospital, in 1247. Early views of society linked mental health (conditions such as epilepsy) to evil forces or witchcraft. It could be argued this was early evidence of labelling and stigma. Society†¦show more content†¦In contrast, the nature vs nature debate heavily influences this subject. Are people born with mental illness or is it developed or is there an overlap between the two? Hans Eysenck argued that there were similarities between how a mental illness is acquired and the development of criminality; schizophrenia is often hereditary, however not all siblings will inherit it and it can be acquired without any hereditary element. Both genetic and social factors, such as drug or alcohol abuse can lead to mental illnesses and as society has developed, the latt er is now much more prevalent. Systematic care was not seen until 19th Century, moving away from institutions to a system that was more segregative, centralised and managed (Rogers, A. Pilgrim, D. 2001). The Victorian era saw scientific theory replacing religious belief around mental illness and psychiatry emerged as a new discipline. The first link between mental and physical illness followed the 1926 Royal Commission on Lunacy and Mental Disorder which stated that Mental and physical illness should now be seen as overlapping and not as distinct . The 1959 Mental Health Act was the first evidence of community care and in the 1960s, following advances in medicine and drug treatment, more focus on rights of individuals, and advances in social science and philosophy combined to start deinstitutionalisation. Treatment for people with mental illness has developed from incarceration in
