The Simplex Solution Method Essay Example for Free

The Simplex Solution Method Essay The simplex method is a general mathematical solution technique for solving linear programming problems. In the simplex method, the model is put into the form of a table, and then a number of mathematical steps are performed on the table. These mathematical steps in effect replicate the process in graphical analysis of moving from one extreme point on the solution boundary to another. However, unlike the graphical method, in which we could simply search through all the solution points to find the best one, the simplex method moves from one better solution to another until the best one is found, and then it stops. The manual solution of a linear programming model using the simplex method can be a lengthy and tedious process.Years ago, manual application of the simplex method was the only means for solving a linear programming problem. Now computer solution is certainly preferred. However, knowledge of the simplex method can greatly enhance one’s understanding of linear programming. Computer software programs like QM for Windows or Excel spreadsheets provide solutions to linear programming problems, but they do not convey an in-depth understanding of how those solutions are derived. To a certain extent, graphical analysis provides an understanding of the solution process, and knowledge of the simplex method further expands on that understanding. In fact, computer solutions are usually derived using the simplex method. As a result, much of the terminology and notation used in computer software comes from the simplex method. Thus, for those students of management science who desire a more in-depth knowledge of linear programming, it is beneficial to study the simplex solution method as provided here.

Factors change Essay After I have recorded all the results and written into tables, I used the data to make graphs, which are voltage against current. When I finished marking all the points on to the graphs, I put a line of best fit through. There are five graphs in total, each represents a thickness, on a graph there are five lines of best fits, and each represents a length of a thickness. Then I pick a point on the lines of best fits and calculate the gradient (resistance) by dividing the point on y-axis (voltage) by the point on the x-axis (current) as the ohms law states that V=IR. Finally, I have to draw five graphs to show the relations between length (on the x-axis) and resistance (on the y-axis). Also, I have to draw another graph to show the relations between thickness (on the x-axis) and resistance (on the y-axis). Evaluating Although the whole experiment has been going very well, but the results seems to show some bias or errors as in one or two of the graphs, the pattern is quite strange because some of the gradient (resistance) is not proportional to the lengths. Overall, the experiment can be said as a success. The aim of this experiment is to measure how the resistance change as the factors change. There are so many variables-temperature of surroundings, length, thickness, material, temperature of the wire, surface area, magnetic properties, coated or not and purity-that can be chosen to measure in this experiment. But in this experiment I am only going to measure two of them, which are length and thickness because these two are the easiest to measure and show the effects on the resistance. Prediction: The result should be showing that the resistance increase as the length or thickness increase. This happens because when length or thickness increases, the current will decrease. As the voltage wont change, if the current decreases, then the resistance will increase. Method: In the experiment I will need to use apparatus listed below.

John Keats: Ode On A Grecian Urn

John Keats: Ode On A Grecian Urn Thou still unravishd bride of quietness[im1], Thou foster-child [im2]of silence and slow time, Sylvan [im3]historian, who canst thus express A flowery [im4]tale more sweetly[im5] than our rhyme: What leaf-fringd legend haunts[im6] about thy shape Of deities or mortals, or of both,[im7] In Tempe [im8]or the dales of Arcady[im9][im10]? What men or gods are these? What maidens loth? What mad pursuit? What struggle to escape?[im11] What pipes and timbrels? What [im12]wild ecstasy? Heard melodies are sweet, but those unheard[im13] Are sweeter; therefore, ye soft pipes[im14], play on; Not to the sensual ear, but, more endeard, Pipe to the spirit ditties of no tone[im15]: Fair youth, beneath the trees, thou canst not leave Thy song, nor ever can those trees be bare;[im16] Bold[im17] Lover, never, never canst thou kiss, Though winning near the goal yet, do not grieve; She cannot fade[im18], though thou [im19]hast not [im20]thy bliss, For ever wilt thou love, and she be fair![im21] Ah, happy, happy [im22]boughs! that cannot shed Your leaves, nor ever bid the Spring adieu; And, happy melodist, unwearied[im23], For ever piping songs for ever new;[im24] More happy love! more happy, happy love! For ever warm and still to be enjoyd, For ever panting[im25], and for ever young; All breathing human passion far above[im26], That leaves a heart high-sorrowful and cloyd[im27][im28], A burning forehead, and a parching tongue. Who are these coming to the sacrifice? To what green altar, O mysterious priest, Leadst thou that heifer lowing at the skies, And all her silken flanks with garlands drest? What little town by river or sea shore, Or mountain-built with peaceful citadel[im29], Is emptied of this folk, this pious morn? And, little town, thy streets for evermore Will silent be; and not a soul to tell Why thou art desolate, can eer return. O Attic shape! Fair attitude! with brede Of marble men and maidens overwrought[im30], With forest branches and the trodden weed; Thou, silent form[im31], dost tease us out of thought As doth eternity: Cold Pastoral![im32] When old age shall this generation waste, Thou shalt remain, in midst of other woe Than ours, a friend to man, to whom thou sayst, Beauty is truth, truth beauty[im33],-that is all Ye know on earth, and all ye need to know. Background: Keats felt inspired after reading two Benjamin Haydon articles, he was aware of Greek art and he had first hand exposure to the Elgin marbles. Reinforced his belief that Greek art was idealistic and captured Greek virtues which form the basis of the poem. He wrote the Odes when he left his job as assistant house surgeon in London, to devote himself entirely to the composition of poetry. Living with his friend Charles Brown, the 23-year-old was burdened with money problems and despaired when his brother George sought his financial assistance. Relationships between the soul, eternity, nature, and art. Keats was a second generation of Romantic poet, he took a polite subject a study of a Greek pot commonly spoken about by the Augustans and traditional odes and turned it into a loud, over-the-top celebration of music, sex, and youth. Structure: Attempted to write sonnets but found the rhyme scheme did not match the message he was trying to convey, so he turned to the ode form. But he found the Pindaric form inadequate for discussing philosophy. So, he developed his own kind. Further altered his ode style for Nightingale and Grecian Urn by adding a secondary voice- creating a dialogue. Keats uses ekphrasis, (the poetic representation of a painting or sculpture in words) but differently from Theocrituss Idyll, a classical poem describing a design on the side of a cup, Theocritus describes motion and underlying motives whilst Keats focuses solely on the external features of the cup but makes the reader think about the underlying motives. Ten-line stanzas, beginning with an ABAB rhyme scheme (alternate rhyme) and ending with a Miltonic sestet (1st and 5th stanzas CDEDCE, 2nd stanza CDECED, and 3rd and 4th stanzas CDECDE, the Keatsian Structure). The same overall pattern is used in Ode on Indolence, Ode on Melancholy, and Ode to a Nightingale (though their sestet rhyme schemes vary), which unify the poems in structure as well as theme. Creates the sense of a two-part thematic structure as well. The first four lines of each stanza roughly define the subject of the stanza, and the last six roughly explicate or develop it. Ode in Greek, means sung. While ode-writers from antiquity adhered to rigid patterns of strophe, antistrophe, and epode, the form by Keatss time had undergone enough transformation that it represented a manner rather than a set method for writing a certain type of lyric poetry. Keatss odes seek to find a classical balance between two extremes, and in the structure of Ode on a Grecian Urn, classical literature and the asymmetry of Romantic poetry. The use of the ABAB structure in the beginning lines of each stanza represents a clear example of structure found in classical literature, and the remaining six lines appear to break free of the traditional poetic styles of Greek and Roman odes. Keats metre reflects a conscious development in his poetic style. The poem contains only a single instance of medial inversion (the reversal of an iamb in the middle of a line), which was common in his earlier works. Keats incorporates spondees in 37 of the 250 metrical feet. Caesurae are never placed before the fourth syllable in a line. The word choice represents a shift from Keats early reliance on Latinate polysyllabic words to shorter, Germanic words. In the second stanza, Ode on a Grecian Urn, which emphasizes words containing the letters p, b, and v, uses syzygy, the repetition of a consonantal sound. The poem incorporates a complex reliance on assonance, which is found in very few English poems. Line 13 where the e of sensual connects with the e of endeard and the ea of ear connects with the ea of endeard. A more complex form is found in line 11 the ea of Heard connecting to the ea of unheard, the o of melodies connecting to the o of those and the u of but connecting to the u of unheard. Themes: Like many Keatsian odes, Ode on a Grecian Urn discusses art and arts audience. He relied on depictions of natural music in earlier poems, and works such as Ode to a Nightingale appeal to auditory sensations while ignoring the visual. Keats reverses this when describing an urn within Ode on a Grecian Urn to focus on representational art. He previously used the image of an urn in Ode on Indolence, depicting one with three figures representing Love, Ambition and Poesy. Of these three, Love and Poesy are integrated into Ode on a Grecian Urn with an emphasis on how the urn, as a human artistic construct, is capable of relating to the idea of Truth. The images of the urn described within the poem are intended as obvious depictions of common activities: an attempt at courtship, the making of music, and a religious rite. The figures are supposed to be beautiful, and the urn itself is supposed to be realistic. Although the poem does not include the subjective involvement of the narrator, the description of the urn within the poem implies a human observer that draws out these images. The narrator interacts with the urn in a manner similar to how a critic would respond to the poem, which creates ambiguity in the poems final lines: Beauty is truth, truth beauty, that is all / Ye know on earth, and all ye need to know. The lack of a definite voice of the urn causes the reader to question who is really speaking these words, to whom they are speaking, and what is meant by the words, which encourages the reader to interact with the poem in an interrogative manner like the narrator. The urn, as a piece of art, requires an audience and is in an incomplete state on its own. This allows the urn to interact with humanity, to put forth a narrative, and allows for the imagination to operate. The images on the urn provoke the narrator to ask questions, and the silence of the urn reinforces the imaginations ability to operate. This interaction and use of the imagination is part of a greater tradition called ut pictura poesis the contemplation of art by a poet which serves as a meditation upon art itself. In this meditation, the narrator dwells on the aesthetic and mimetic features of art. The figures on the urn within Ode on a Grecian Urn lack identities, but the first section ends with the narrator believing that if he knew the story, he would know their names. The second section of the poem, describing the piper and the lovers, meditates on the possibility that the role of art is not to describe specifics but universal characters, which falls under the term Truth. The three figures would represent how Love, Beauty, and Art are unified together in an idealised world where art represents the feelings of the audience. The audience is not supposed to question the events but instead to rejoice in the happy aspects of the scene in a manner that reverses the claims about art in Ode to a Nightingale. Similarly, the response of the narrator to the sacrifice is not compatible with the response of the narrator to the lovers. Narrator contemplates where the boundaries of art lie and how much an artist can represent on an urn. The questions the narrator asks to reveal a yearning to understand the scene, but the urn is too limited to allow such answers. Furthermore, the narrator is able to visualise more than what actually exists on the urn. This conclusion on art is both satisfying, in that it allows the audience to actually connect with the art, and alienating, as it does not provide the audience the benefit of instruction or narcissistic fulfilment. Besides the contradictions between the various desires within the poem, there are other paradoxes that emerge as the narrator compares his world with that of the figures on the urn. In the opening line, he refers to the urn as a bride of quietness, which serves to contrast the urn with the structure of the ode, a type of poem originally intended to be sung. Another paradox arises when the narrator describes immortals on the side of an urn meant to carry the ashes of the dead. In terms of the actual figures upon the urn, the image of the lovers depicts the relationship of passion and beauty with art. In Ode to a Nightingale and Ode on Melancholy, Keats describes how beauty is temporary. However, the figures of the urn are able to always enjoy their beauty and passion because of their artistic permanence. The urns description as a bride invokes a possibility of consummation, which is symbolic of the urns need for an audience. [im1]Apostrophe: Silences the Urn and projects a voice, his own onto it allowing him to speak on its behalf. [im2]Married to Mr. Quietness but they have never consummated their marriage despite ravished imagery. Also, adopted by silence and time but these were not the originally circumstances, the true parent is the silent painter and ceremonial use. After the decline on Greece the pot continued to live on. [im3]Means Forest, the Urn is a historian of people of the woods. [im4]As well as the bee imagery flowery is a pun as a flowery tale is very complicated, also an urn had a flowery or leafy border. [im5]Flower and sweetly is metaphor for bees and nature, he believes that the Urn can tell a better story, with nature like unlike poetry, both are true beauty and show nature. [im6]Exist in one place- but has obvious connections to the supernatural and the dead characters. [im7]In ancient Greece Gods were represented as normal people so it would be hard to tell the difference, Gods also liked to be in company with people. In a way, the poems rigid rhyme and meter is very understated bringing parallels to God. Effortless on the surface highly intricate underneath you wouldnt know what you were looking for unless you sough it out.. [im8]The Vale of Tempe was home for a time to Aristaeus, son of Apollo and Cyrene, and it was here that he chased Eurydice, wife of Orpheus, who, in her flight, was bitten by a serpent and died. In the thirteenth century AD a church dedicated to Aghia (Saint) Paraskevi was erected in the valley. [im9]Tempe and Arcady are allusions to two regions of Ancient Greece known for being particularly lush and green. They become stock symbols in English poetry for places where people lived in the forest. [im10]Vision of pastoralism in nature. [im11]USE of ekphrasis, the poetic representation of a painting or sculpture in words. [im12]Repetition of questions (anaphora) that the speaker cannot comprehend draws parallels to the interaction between Job and God. Something that is godly like nature or beautiful art is incomprehensible for man we can do our best to try to understand it only. [im13]ASSONANCE: ea of Heard connecting to the ea of unheard, the o of melodies connecting to the o of those and the u of but connecting to the u of unheard. [im14]Unlike the wild party music in the chase in stanza 1 the soft pipes give a soothed atmosphere [im15]Paradox: the sweetest melodies are the ones that you do not hear. Keats is tricking the audience: he treats the people as if they are real people in real events living on the Urn just in frozen time The Urns beauty allows him to think of a song in his head that the man is playing and its more beautiful than anything that he has ever heard before. Aka he prefers the fantasy world to the real one. [im16]Edenic, it shall always be spring here with the man under the tree always playing his sweet music for his spirit. [im17]Another apostrophe [im18]No surprise that he is so obsessed with immortality, he had just contracted TB.. [im19]Greece had connections to higher society and was rebellious, he uses anachronistic diction to make this connection with the constant repetition of thou- its made to sound fancy. [im20]Keats says not to grieve but continues to use negative phrasing even in these lines: do not grieve, cannot fade, and hast not thy bliss. Keats may have made a mistake, or there may be a reason for this negative undertone [im21]SYZYG: Repetition of the consonant sound b v p in particular, breaking his reliance on Latinate polysyllabic words to shorter, Germanic words. [im22]Potentially trying to convince himself that he is happy allegorically he is actually happy. [im23]Pronounced un-wear-i-ed to preserve the iambic pentameter. Potentially comparing himself to the happy melodist who too draws out notes/syllables. [im24]Stuck in the same time forever its always new nothing shall ever grow old. [im25]Repetition shows the eternal nature of the urn which is observed here. Panting from being chased in S1 as well as sexual connotations. Alternatively, with the rhythm pulsating and the repetition of speech he is growing sexually excited himself. [im26]Could be the speaker standing above the urn or it could suggest that the lovers are better of above human passion and they are actually all Gods, preserved and beautiful- living on forever as long as they are remembered. [im27]If it is the speaker standing high above then it must be his heart that is sorrow filled, looking at those in love sadden him. Uses metonym to connect them. Words that give meaning to another i.e. Westminster = House of Parliament, Downing Street = Prime Minister. [im28]Too much of something good. [im29]Oxymoron peaceful fortress [im30]Overcomplicated- too good for us Godly. [im31]Apostrophe and personificationÂÂ   is cyclical like looking around the urn in a circle. [im32]The poet compares the experience of looking at the urn to thinking about eternity, an idea so lofty and hard to understand that trying to think about it is like not thinking at all. [im33]Simple chiasmus acts as synecdoche for the poem. Due Process and Crime Control Models: Compare and Contrast Due Process and Crime Control Models: Compare and Contrast The purpose of this paper is to research both the Due Process and Crime Control Models. After researching each of the topics, they will be discussed in further detail. Both of the models will be compared and contrasted as well. Both of the models have proven to be well known and used throughout the United States, as well as many other parts of the world; both models have been used since the 1960s. The contemporary state court system status and the model that is used there will be discussed further in the paper. Both of the models named above are very complex systems that are used in criminal justice systems throughout the United States as well as many other parts of the world. The models were developed as some type of guideline to aid in the arrest and prosecution of criminals. The purposes of the two models are to help maintain safety is society, as well as protect the rights of the suspect in various situations and scenarios. In order to fully understand both of the models, each system must be viewed separate and together. Various models and techniques have been used in the criminal justice system since its development, some of the models have been more structured than others, some have been less structured than others. When evaluated, some of the different models have worked well in some areas, while other models have not appeared to be beneficial at all. Literature Review Choongh (1998) provided readers with information regarding the limitations of Packers crime control and due process models, which were developed in the 1960s. Choongh informed readers that the crime control model follows procedures very closely, as well as screen suspects, determines guilt, and secures punishment all according to written policies, procedures, and laws. Choongh suggested that there are some problems with the model. One of the problems is that the model defines efficiency by speed and finality. This could possibly be beneficial in some ways, but could also cause harm in other ways; the quicker the investigation the more likely that the work may be incomplete or sloppy. The due process model is more concerned with individual integrity and autonomy. The main purpose of the due process model is to maintain close control over the power of the state. Choongh reported that neither model is effective, this is because the investigations are not thorough enough, court processes are rushed, and prosecutors and law enforcement rush to accusing a person of guilt rather than taking their time and finding the real villain. Henham (1998) provided readers with information about the rights-based approach. The author explained that there is a large need for a rights-based approach to be used for criminals during the sentencing process. Henham feels that the crime control model and the due process model are not adequate. The crime control model is based on repressing criminal activity and maintaining a low crime rate. The due process model focuses mainly the protection of the individual through stressing adherence to courtroom procedures. The rights-based approach is concerned to postulate a number of fundamental normative propositions that have moral, rather than empirical validity. The crime control model and the due process model do not provide adequate choices to criminals when mental health problems are involved, but a rights-based approach would address several areas that the other models do not address. Henham felt that people who suffer from different mental disorders are essentially being discrimin ated against, by not providing for their need. Schrieber, Renneberg, and Macracker (2009) and Tucker, Hasselt, and Russell (2008) all wrote about the criminal justice system, mentally ill patients, and the professionals inadequate training for dealing with the mentally ill. All of the above authors agreed that there is a great need for special training and possibly special crime models that should be used when police are dealing with mentally ill criminals. Recently there has been a rise in the number of cases that law enforcement officials have responded to in which mentally ill individuals were the reason the police were called. Schrieber, Renneberg, and Macracker reported that the criminal justice system is not capable of dealing with offenders who suffer from mental disorders that uncontrollable. Recent studies have shown that law enforcement officials have are generally the first contact with mentally ill suspects in criminal cases, but also in many cases that are not criminal and have to be dealt with through social service programs. The authors reported that the models need to be reorganized so that the criminal justice system will be more sensitive to individuals who suffer from major depression, post traumatic stress disorder, schizophrenia, and psychosis. Rehabilitation is very important for individuals who have these disorders and the treatment that they need is not offered in many of the detainment facilities that criminals are sent to. Klein (2006) wrote about the crime control model. She reported that the crime control model has a very reliable process for screening suspects, and many of the criminals that are charged with crime using this model, will spend time in jail or prison, because the system is so reliable. Klein also wrote about the due process model and how it helps an individual to maintain some autonomy during the criminal justice process. Even though there is room for improvement in the areas of pleading and discovery, Klein supports most of the aspects in each model and the basis behind them. Duff (1998) wrote about the crime control model and the due process model and how the models are viewed in the criminal justice system. Duff reported that the due process model does not agree with the majority of cases in which criminal are sanctioned for their crimes, this is because if the crimes do not involve any harm to others, Duff feels that the criminal should be punished les severely. Roach (1999) provided readers with information about four different models used in the criminal justice system. Roach directed more attention to the due process model and the crime control model. Roach explained Herbert Packer provided professionals with a guide to criminal justice systems by using these models. Both of the authors reported that if the crime control model is used correctly, most criminals plead guilty to the charge or the prosecuting attorney withdrawals the charges. Roach, as well as Duff reported that both models were not only efficient, but also very durable in order to with stand as many years as they have. Edkins (2007) provided readers with information about the due process model and its purpose of helping suspects maintain their individual rights during the criminal justice process. Edkins also provided readers with information about the crime control model and its purpose of making sure that all convicted criminals have harsh punishments. Edkins gave information about seven different studies that were completed which measured attitudes about the due process and crime. Vance and Trani (2008) conducted numerous studies on the crime control model and the due process model. The authors are not in agreement with the crime control model, but they do support the due process model. Vance and Trani reported that both of the models have ethical standards and should be supported across the board, but the in some places, law enforcement and prosecuting attorneys will not support either of the models. The authors reported that there are many reasons for different crime models, some of these purposes are to help catch criminals, detain them, and reduce crime. Arias and Ungar (2009) wrote about Latin Americans and the impact that the two models have on their lifestyle. The authors informed readers that the purpose of the crime control mode is to reduce crime and the purpose of the due process model is to protect individual rights of the accused when it is used as a guide for the criminal justice process. Discussion Due Process The basis of the due process model is formal structure. When used correctly, the due process model protects the rights of suspects accused of various crimes. The due process model reduces many errors that occur during the investigation, arrest, evidence gathering, and trial. Due process does not support much of the evidence that is used in many criminal trials, and there are many reasons and factors for this. Basically, the due process model criticizes every type of evidence except definitive physical evidence that cannot be disputed. The object of looking at evidence in the due process model is deciding what information may be incorrect, falsified, or coerced from an individual. This has occurred on many occasions when other criminals have testified against the suspect, because they may be rewarded with time off of their sentence or other things. Because the main goal of the due process model us to reduce mistakes that can place an innocent person in prison, the process is very slow (Henham, 1998 Klein, 2006). Crime Control The idea of the crime control model is to decrease crime in all areas; for this to be done criminal conduct needs to be drastically reduced. Many of the problems that arise in the crime control model is directed at law enforcement officials. People commit crimes and get away with them, then it may create a higher crime rate because their likely to be more followers. The crime control model directs more attention in investigating, screening people, establishing guilt, seeking harsher punishments for individuals who have committed crimes (Roach, 1999). For the crime control model to work appropriately, the processes must be efficient. Higher arrest and conviction rates need to be seen, as a way of deterring other people from committing crimes. The investigation and arrest process needs to be expedient, so that fewer resources are used on each client. The main purpose of the crime control model is for the there to be enough evidence gathered that the suspects pleads guilty to the charges, and there is no need to waste time, money, or effort on a trial that may last for a unknown amount of time (Duff, 1998). The crime control model utilizes law enforcement officials and prosecuting attorneys to establish the innocence or guilt of a suspect early during the investigation. Individuals who are most likely guilty of committing such crimes progress through the criminal justice systems with great speed; they either plead guilty to such crimes, or they are found innocent or guilty in a criminal trial. , the less likely to find the evidence needed, and the more money spent on the investigation (Klein, 2006). Similarities and Differences between the Two Models The main goal of the due process model is for individuals to be treated fairly in the criminal justice system, so they will not be deprived anything that they deserve in life of they are innocent. The due process model explains that all individuals have a right to freedom and security, unless they are guilty of committing a crime. The crime control model does not hold an individuals rights in high regard, and feels that criminals should be caught at all cost (Roach, 1999). The crime control model puts a lot of their trust into law enforcement officials and prosecuting attorneys to complete the criminal investigations. Depending on the amount of work put into the investigation and the quality of the work that is done, many suspects will either plead guilty, therefore there is no trial. Speed and finality two tasks the crime control model looks to complete (Roach, 1999). When people are arrested for a crime, they are seen as innocent until they actually admit to or are convicted of such crimes (Klein, 2006). When dealing with the due process model, policing society in a positive nature becomes a very vital issue. Followers of the crime control model feel that the number of arrests may deter other criminals from committing crimes, by showing them that the criminal justice system does work (Klein, 2006). Much of the population is in favor of the due process model, because of reasons such as equality, human rights, and freedom. Undert the United States Constitution each individual has certain rights, and the due process model helps to maintain and restore these rights (Henham, 1998). Law enforcement agencies generally prefer the crime control model; they treat suspects who are arrested as though they have already been found guilty (Henham, 1998). The due process model protects individuals with the 4th and 8th amendments which address the issues of illegal searches on individuals suspected of crimes, as well as the right not to incriminate ones self (Choongh, 1998). State Court Systems Model of Choice It appears that each of the models are very unique and are used for different purposes. Just as different defense attorneys have different styles and models that they follow, so do law enforcement officials and prosecuting attorneys. The model that is used is completely up to the individual who is gathering the information and investigating the crime. In an ideal world, the due process model would be the model of choice, because it helps keep the rights of individuals intact, as well as serving its purpose in the criminal justice system. Both the crime control model and the due process model have a positive side as well as a negative. The United States criminal justice system and judicial system has debated the subject of which models are the most beneficial for numerous years, but no common ground has been reached. Two of the main factors that are looked at when making a decision such as this are, which model helps maintain social order, and which model helps reduce the risk of imprisoning innocent individuals. As close as these two factors are related, the answer should be simplistic, however it is not. In the criminal justice system, these factors actually conflict with one another, therefore there is not a common system that came be used for both of the factors. Maintaining and restoring social order is best maintained by the crime control model, whereas protecting individual rights is best maintained by the due process model (Edkins, 2007). The population that law enforcement officials are serving may affect the crime model that they decide to use. Areas with high crime rate may be better served by using the crime control model, whereas areas with less crime may be better served by the due process model. Along with the population, the type of crimes that are being committed may also be a factor in which model is chosen. Areas that suffer from drug trafficking and violence may be best served by using the crime control model, whereas areas that suffer from trespassing and burglaries may be best served by using the due process model. The crime control model implies that law enforcement and prosecuting attorneys act promptly to allegations and investigate them more thoroughly at a later time, but the due process model requires careful consideration in each and every case, prior to arresting individuals (Duff, 1998). Conclusion Both of the models have very different key points. Both of the models have different methods that are used to reach a common goal. If the main goal of the United States Criminal Justice System is to maintain social order and protect the rights of individuals, then there is no way to utilize just one of the two models. The crime control model appears to be the best model used for maintain and restoring order in society. In the ideal world, decisions would not be made in haste. But in order to complete a job and catch certain criminals, then there has to be room for quick decisions, even if it becomes clear that the decisions that were made were wrong. Each state, county, and city has their own way of operating and reducing crime. Unfortunately at times innocent people are brought into the mix, this is a chance that has to be taken in order to have a fully functioning criminal justice system. Scholars have researched for many years how to make the criminal justice system work by following one model, but at this time nobody has been successful in developing such a model. Family: Social Construct And Institution Family: Social Construct And Institution In this essay I intend to discuss the family as a social construct and institution. I will be critically discussing the different forms of the family, and the role of the family within society from four sociological perspectives. The family as a social structure is often taken for granted to mean a married couple with children, possibly incorporating grandparents and directly linked blood relatives. This stereotypical view does not take into account a changing society with changing norms and values. It is important when discussing the family in a sociological context to define the family in a wider perspective. Ferrante (2011) suggests that the family is often described as a social institution that binds people together through various means, blood, marriage, norms and law. According to Zelditch (1964) as cited in Ferrante (2011) there is no concrete group which can be universally identified as the family. Several institutions including political parties, the legal system and the media have been blamed for creating the cereal packet family but not all sociologists agree with what appears to be typical British family. Gittins (1993) as cited in Marsh and Keating (2006) states The ideology of the family would have us believe that there is one type of family, one correct way in which individuals should live and interact with each otherAn ideology that claims that there is only one type of family can never matched in reality, for it represents an ideal to which only some can approximate, an others not at all. During the last century the concept of the family has altered, this is partly due to industrialisation, modernity, changing norms and values and the media. The family can now be seen to have many dimensions, what was considered to be deviant or diverse is often accepted as a norm. Some sociologists argue that during the nineteenth century, post industrialisation, social order, or kinship, a network of relatives (kin) who are connected by common decent or marriage. (Fulcher and Scott 2007) began to alter. Communities that were based on traditional shared values of religion and community changed. Cottage industries began to disappear and families moved from rural areas into towns and cities the nature of the of kinship began to diminish. The economic and social life of this type of family relationship changed, according to Ritzer and Ryan (2011) Rural people were lured by the novelty of city life and the prospects of greater economic opportunity. The domestic economy of the pre-industrial family disappeared. The industrial revolution provided factory work for men leaving the females to take a more prominent role as the caregivers, the family dynamics began to alter creating a major change in the division of labour within the family. Industrialisation was identified by many as having sounded the death knell for this way of life, destroying extended families and undermining communities. (Ogburn 1955 as cited in Gillies 2003). The extended family tends to include generations of family extending both horizontally and vertically including connections my marriage and blood. It is argued by some sociologists that industry has destroyed the traditions of the extended family and the social bonding of kinship, leading to the nuclear family. Talcott Parsons (1949) as cited in Fulcher and Scott (2007) stressed that in the absence of the extended family and kinship, the nuclear family met the needs of a changed society. However Laslett and Wall (1972) as cited in Fulcher and Scott (2007) suggest that the nuclear family has always been the more dominant family type throughout the history of family life. The functionalist approach to the family suggests that the family itself is responsible for ensuring that vital tasks are achieved. Functionalists believe that social institutions such as schools, churches, political systems and the family are all essential to the structure of an effective functioning society and all of these institutions inter relate with each other for the benefit of the whole of society, if one aspect of the structure does not function adequately then society will inevitably experience some form of failure and conflict. Functionalists suggest that the family is one of the most important institutions responsible for the successful raising of a child and parents play a key role in ensuring that children become well integrated within society. Murdock (1949) conducted a study based on two hundred and fifty societies with the aim of discovering if the family was universal. His conclusion was that the nuclear family was a universal social institution that comprised of four basic functions. These he called, sexual relationships, economic cooperation among members, reproduction and the socialisation of infants and children. (Stark, 2010) Murdocks theory has been criticised by many non functionalist sociologists suggesting that his study focussed on the nuclear family and did not take into account other family forms. Gough (1959) argued that Murdocks theory did not take into account societies such as the Nayar, where one woman could have up to twelve potential fathers to a child and a man could have an unlimited amount of wives. Support came from brothers, sisters and children not from potential fathers. This system was based purely on kinship groups. Gough suggests that the existence of the Nayar was not based on economic cooperation between husbands and wives, the socialisation of infants was provided by the women and their kinship groups, and any affectionate relationship between men and women was prohibited. Goughs criticism can be closely compared to family groups in British society today looking at family units that do not meet Murdocks nuclear family theory these families could be single parent families or fami lies consisting of same sex couples. (Bell 1968) Parsons (1959) as cited in Macionis (2012) argued that the family retains two primary functions, these functions are found in all forms of family thought out the world. He suggests that the primary socialisation of children is the first and most important setting for child rearing and parents are in the position to ensure children are able to become well integrated into society and the structuring of the personality in the early years leads to contributing members of society. He acknowledges that family socialisation continues throughout the life cycle but secondary socialisation becomes more dominant as the child develops due to the family being less involved, and agencies such as schools and peer groups become involved. Parsons as cited in Harolambos and Holborn (2008) argued that families are factories which produce human personalities. Parsons second observation of the family was the stabilisation of the adult personality arguing that men and women who have deep personal relationships will lead content and fulfilling lives which in turn will improve family life removing some of the tensions that the family may face such as work and relationships. Marxist sociologists may argue that although family life can be fulfilling and happy the fact that contemporary British society is based on capitalism, which results in exploitation, family members will inevitably be placed under financial strain and tension which can cause problems of discontent and the breakdown of the family unit. Criticisms were that his theory was outdated and based on the ideology of the nuclear family alone. Marxist writers in the 1970s put forward a different perspective of the family they argued that the capitalist system exploits the free domestic labour of the housewife through the domestic division of labour. (Fulcher and Scott 2007). They argue that the concept of the nuclear family promotes the role of the man to be the breadwinner and the woman to be the housewife which has led women, if wanting to work, becoming the reserve army therefore being called upon when required, for example during times of war, according to Marxist theorists the nuclear family provides employers with cheap disposable labour that tends to be less valued than their male counterparts. (Fulcher and Scott 2007) On what foundation of the present family, the bourgeois family based? On capital, on private gain. In its completely developed form this family exists only among the bourgeoisie The bourgeois claptrap about the family and education, about the hallowed correlation of parent and child, becomes all the more disgusting, the more, by the action of modern industry, all family ties among the proletarians are torn asunder, and their children transformed into simple articles of commerce and instruments of labour. (Marx and Engels, 1848 as cited in Ferrante 2011) Although Marx and Engels seem to be criticising the family and suggesting that the family may be considered as a tool for capitalism they were in fact suggesting that the family should be improved and it was the traditional family types that approved of the exploitation of women and children. According to Marsh and Keating (2006), Engels believed that the family exploited women and children and the end of the exploitation within the family could only be achieved in a communist society. The development of the Marist perspective continued throughout the century and the views of Engles and Marx were applied to a modern capitalist society. Modern Marxists would argue against the functionalists who stress that the purpose of the family is to raise children. Marxists agree that the family has a job but that job is to reproduce the labour power that maintains a capitalist society. It is also suggested that the family is a control mechanism that exerts social control on parents. Living in a highly consumer orientated society, children are often in competition with their peers and parents are in competition with other parents to ensure that their children have the best technology and prospects, the pressure to remain in a competing capitalist society gives the parents little choice but to compete in the workplace and accept capitalism as a norm. The family is thus an integral part of what Marxists call commodity fetishism; it helps to fuel the creation of false needs, which in order to be satisfied, require people to work hard. Mobile phones, laptops, X-boxes; all these frivolous things need to be bought by someone and in western capitalist societies it is now increasingly young people who are an important market. And young people come from, of course, families. (Abbot 2010) Historical changes in society have led to changes in feminist perspectives creating several waves of feminism. Although there are several types of feminist views including Liberal, Socialist, Radical and Marxist they do all share a common belief that women experience a range of social, economic, political and personal difficulties in their lives but they dont all agree on the cause of these difficulties. In general feminists have discarded the Functionalist theories of the nuclear family and suggested that many parents have socialised their children to behave in a manner that is considered to be appropriate to their gender roles. Feminists argue that when children see their parents behaving in their appropriate gender role then the children naturally assume that they should behave in the same way. Females have been shown what is considered to be feminine or female, dependence, obedience, conformity and domesticity and males have been encouraged by parents to be dominant, competitive and independent. (Holburn and Steel 2012) The radical feminist perspective of the family agrees basic concept of the Marxist view suggesting that exploitation is a key aspect of the family, however where Marxists suggest that capitalism plays a key role for the exploitation of women the feminist approach suggests that the division of labour is due to genetic predispositions that women are seen as the carers and are more suitable to child rearing that their male counterparts who are seen as the providers. Feminists argue that in the division of labour is unequal and that the domestic role is unrewarded and undervalued. According to Sheeran (1993) as cited in Marsh and Keating (2007) Marxist and radical feminists argue that the family is both an ideological construct and a repressive, socially produced reality, which helps to perpetuate capitalism and / or patriarchy. Such criticisms are overtly anti family, and argue that women have been forced into taking responsibility for child care by that agent of the state, the patriarc hal family. Morgan (1975) as cited in Haralambos and Holborn (2008) suggests that both functionalist and Marxist approaches, both presuppose a traditional model of the nuclear family where there is a married couple with children, where the husband is the breadwinner and where the wife stays at home to deal with the housework. The Interactionist approach is seen to be quite different and works at a micro level rather than the macro level like the previous perspectives. Symbolic interactionism has been an important theoretical perspective in family studies since its early development in the 1920s and 1930s. Symbolic interaction theory describes the family as a unit of interacting personalities. LaRossa and Reitzes (1993) as cited in International Encyclopedia of Marriage and Family (2003). Interactionists suggest that families reinforce and rejuvenate their bonds through the use of rituals. Some social scientists believe that rituals like gathering together for a family meal or the ritual of marriage using symbols to reinforce the bonds this can be seen as a source of family strength and if families preserve rituals then children will become more emotionally equipped to face problems in the future. (Hughes and Kroehler 2011). Critics stress that symbolic interactionism only looks at the micro level and that this perspective does not take into account larger issues of society. The New Right perspective of the family was born from functionalist ideology and supports the theory that the nuclear family is the only type of family that works effectively within British society. Between the 1950s and the 1990s the nuclear family began to alter, families were no longer perceived to be seen in the traditional stereotypical sense, families were becoming more diverse partly due to changes in the law, abortions were legalised, homosexuality decriminalised and the introduction of legislation such as the Sex Discrimination Act and the Equal Pay Act was introduced. New types of families were emerging. Single parent families, reconstituted families, individuals that cohabitated and the formation of same sex relationships that may or may not have had children from previous relationships. The New Right believe that the lack of traditional family and values and diversity has corrupted society. Lone parents were blamed for wayward children suggesting that without a male and f emale parent residing within the family unit then children would not be able to function as contributing members of society. Critics of the New Right suggest that by suggesting that the nuclear family is the only family that works for the benefit of society it ignores the dark side of the family issues such as domestic abuse and by trying to impress that the nuclear family is the superior and morally correct route it creates a them and us situation which can lead to discrimination, persecution and ultimately suggests that other family types are not families at all.(Yorkshire 2011) According to the Office for National Statistics (2011) between 2001 and 2010 families by type have altered slightly to show that there has been a slight increase in the alternative family and a slight decrease in what is considered to be the nuclear family. As the Office of National Statistics now take into account Civil Partnerships as legitimate families the figures reflect a more accurate account of the makeup of the ever changing British family however the categories in which families are assigned do not represent a true picture of the family as it fails to differentiate between reconstituted and nuclear families, while the minority groups such as civil partnership couples and lone parents have been allocated a category of their own. According to Morgan (1994) as cited in Marsh and Keating (2006) We cannot speak of the family as if it were a static and changing thing. Rather it is better to use the word as signifying the character of a complex series of processes over timewe should speak of family processes, family living or family life courses. In this way we will come to recognise that family life is always subject to change and variation that change is at the very heart of family living As society changes with time it can be argued that the family will alter and perceptions of the family from influences such as the media and politics will change the ideology. Although the school of thought may differ depending on what perspective is applied it appears that the family plays an important role within British society, it is important to recognise that without understanding the family it makes it difficult to understand problems that may arise such as domestic violence and child abuse and how they are interpreted as private troubles or public issues.

The Complex Character of King Richard II Essays -- Richard II Richard

The Complex Character of King Richard II A general conclusion of most critics is that Richard II is a play about the deposition of a "weak and effeminate" king. That he was a weak king, will be conceded. That he was an inferior person, will not. The insight to Richard's character and motivation is to view him as a person consistently acting his way through life. Richard was a man who held great love for show and ceremony. This idiosyncrasy certainly led him to make decisions as king that were poor, and in effect an inept ruler. If not for this defect in character, Richard could be viewed as a witty, intelligent person, albeit ill-suited for his inherited occupation. Immediately the reader is shown the adoration of ceremony and drama that Richard holds. He hears the accusations brought to him by his cousin Bolingbroke and Mowbray. Mowbray fearing impartiality on the kings part is reassured by Richard: "impartial are our eyes and ears./ Were he my brother, nay my kingdom's heir...Now by my scepter's awe I make a vow. (I.i.120-123). Notice the love Richard has of his power and of the ceremony itself that the kingship brings with three words, "my scepters awe". Interestingly until this point Richard has used the royal "we" in his speech; here it becomes his personal status. Additionally, he asks them to "be ruled by me" (i.i157) and follows this line with clever poetry. "Lets purge this choler without letting blood./ This we prescribe, though no physician;/ Deep malice makes too deep incision." (I.i.158-160). Richard is showing off his poetic talents, not necessarily his kingly talents. There seems to be a strong feeling that he enjoys this display of his talent. At this point the reader may be amused and entertained by his ... ... He was though very inconsistent. He lapses into moods and publicly displays his feelings. Inconstancy is not the way to rule a country. His entrance into "reality" stems from his adversity with Bolingbroke. Would Richard have matured if not faced with the opposition of Bolingbroke. Sadly the answer seems to be no. Richard was consistently acting through his reign, yet that was his true personality. Such is the paradox that is Richard II.

Impact of M-Commerce in Job Market

The advent of wireless and mobile technology has created both new opportunities and new challenges for the business community. In its present state, M-Commerce can be viewed as an extension of conventional, Internet-based E-Commerce, which adds a different mode of network and accommodates different end users’ characteristics. However, if the predictions stating that mobile and wireless computing will dominate the Internet industry in the future materialize, the E-Commerce and M-Commerce could become a singular blended entity. M-Commerce, as defined by Muller and Veerse, stands for conducting commercial transactions via a â€Å"mobile† telecommunications network using a communication, information, and payment (CIP) device such as a mobile phone or a palmtop unit. In a broader sense, M-Commerce can simply be defined as exchanging products, ideas and services between mobile users and providers. This paper will also give an overview of the characteristics of M-Commerce. We discuss the basic characteristics of M-Commerce that have the potential to influence the basic marketing orientation of both sellers and buyers, and, above all, alter the general dynamics of the market. There are many definitions of m-commerce with differing emphases. Keen and Mackintosh define m-commerce as the extension of electronic commerce from wired to wireless computers and telecommunications, and from fixed locations to anytime, anywhere, and anyone. when something is mobile it means that its primary usage environment is a mobile one. On the other hand, mobility in itself and mobile technology is not necessarily a value; the freedom created and supported with the technology is the key issue. Durlacher define m-commerce as â€Å"any transaction with a monetary value that is conducted via a mobile telecommunication network†. The focus in this definition lies on the exchange of products and services that is associated with a monetary value. They specifically list any kind of service that can be provided by the mobile device, thus expanding the mere commercial character through communicative and informative services. A mobile device is a small smart device. It can be a mobile phone, a communicator or a PDA. It communicates and transfers data (convenience). It is used only by its owner (personalization). It can provide information anytime, anywhere (ubiquity). Capturing the concept of mobility, a user can be contacted anywhere (reachability). A mobile device can provide users? locations (localization). Knowledge of users? precise geographical location allows customized, relevant content to be delivered to them when and where they need it. It can also be used to connect to the Internet (instant connectivity). Ubiquitous interactivity (figure 1) is what makes mobile devices unique. Wireless devices enable users to send, receive, and act on information in real-time, independent of their location. The western mobile and remote workforce is growing, driven by both business necessity and technological innovation. One explanation for increased work mobility is the emergence of service industry as a dominating occupation in the post-industrial society. Service work is often performed, where the customer is, and thus making many services mobile. It is not like manufacturing work; which takes place where the machinery is located. Another factor is the increased cooperation in and between organizations. Some forms of cooperation can take place remotely, but people still need to meet physically. A third important factor for increased mobility is the extensive adoption of mobile technologies. Mobile technologies enable people to be mobile and yet accessible. As people have become accessible independent of place, new ways of working have emerged in many organizations. To describe the mobile worker, new concepts have been coined. Mobile commerce may impact both mobile workers and their enterprises in the following dimensions. Location: The post-industrial workers work at various locations: in their office, at clients? office, at colleagues? office, in the train, hotel rooms, etc. We can thus imagine that during this extensive geographical movement, mobile workers are often away form the â€Å"benevolent dictator†, their desktop computers, which contain most of the information they need and impose rigid constraints on how and where they can be used. With m-commerce the user is put in the centre of information and communication. Information comes to the user instead of the user looking for it. This makes mobile workers able to receive actionable and useful information on demand at the moment of relevance and regardless of their location and extensive movement. Sales reps are examples of workers who are constantly on the road while their effectiveness depends to a large extent on their ability to have immediate access to account information, current prices, order status and market conditions. The importance of immediate access to information by salespeople is well recognized in the personnel selling literature. Salespeople? effectiveness can be enhanced by providing them with market research information and encouraging them to unitize information. With vast amount of relevant information about client’s orders, roduct’s profitability, promotions at their fingertips regardless of their locations, sales reps can adjust their call schedule to adequately target those customers with the highest potential at the right time. Additionally, receiving time-sensitive alerts about customers? latest orders, industry indicators and competitors? actions, may enable sales reps to tailor their sales messages to a specific customer, adapt to opportunities that arise during the sale call and overcome objections. Indeed, many empirical studies find a strong effect of adaptive selling on salesperson performance. Furthermore, M-commerce can enable mobile workers to use more efficiently their dead time. This time generally occurs between tasks and between meetings, in which workers usually have little control over the resources available to them. For instance, pharmaceutical sales reps often visit doctors to provide them with information on what is available as order brochures on products in which the doctor is interested. Frequently the doctor is not available and the representative wants to find a nearby alternative contact. If there is no alternative contact to visit, then the time for waiting for the doctor to become available may turn to be dead time for the sales representative. With m-commerce, the sales reps can turn this dead time into a productive one by performing non-selling tasks such as completing and sending expense reports to their company, preparing invoices or writing and sending thanks letters to customers. These reduce the time that sales reps have to spend in the office to perform routine tasks and thus allow them to spend more time selling. Indeed, McGraw Hill’s study of 239 salespeople across 198 different companies reveals that salespeople spend on the average about 25% of their time waiting for interviews with clients and travelling. Using dead time more efficiently may occur in a variety of locations (i. e. trains, airports, airplanes, hotels rooms, office buildings, etc). Additionally, mobile workers spend considerable portion of their time on the road, Awareness of their geographical position by the network can allow relevant support and alerts be sent to theme. Examples of such alerts are â€Å"there is a traffic jam two kilometers ahead, use the alternative highway†, â€Å"there is a restaurant offering 10% discount in avenue X â€Å", I have a breakdown, in nowhere, send me a tow truck†, †your client X is in the avenue ahead to you †. Interaction: Asynchronous communications enabled by emails has made co-workers interactions with others more flexible. However, asynchronous communication inevitably creates time lag. Until a receiver of an email actually goes to his computer and read the email, the communication does not come into effect in practice. Moreover, email communication requires a computer and software, which are mostly fixed to a certain location such as an office and home. M-commerce may enhance interaction among distributed workers and others by enabling them to have access to corporate resources, send and receive emails regardless of their location. For instance journalists on the move are often faced with situations in which they have to report events on topics on which they are not fully profound with. Also reporting is often conducted away from editorial staff and radio TV / station’s resources. In such a case M-commerce can provide support to journalists by enabling them, irrespective of their locations, to connect to their TV/Radio station’s intranet. The system can then provide them with the list of resources available on the topic they want to cover together with contact details of colleague who have expertise in such topics. The journalists can then either use the available resources to get an understanding of the topic or elect to contact their colleagues for more interaction. Additionally, ubiquitous access to e-mails and corporate data by mobile workers may enable them to make themselves readily available to address customer problems and questions. Reducing the time it takes to deal with a client’s concern or difficulty may have a positive impact on customer orientation, the degree to which the seller is perceived by the buyer to put customer’s need first. Indeed, customer orientation is a key enabler of buyer-seller relationship developments. Operations: we are witnessing the emergence of new forms of organization, in particular virtual Corporations. Virtual corporations could not exist without an effective information exchange and efficient coordination of the members. This applies also to other management initiatives such as project team or task force. But it is sometimes challenging for corporations to ensure fast coordination among co-workers while they are on the move even if they introduced Internet technologies such as email in their work practices. M-commerce can act as the â€Å"glue† among distributed members, by connecting them more tightly regardless of their locations. This may for instance make it possible for marketing managers to use real time data flowing from the field to evaluate the results of promotions and new product introductions more rapidly and communicate their reactions (i. e. promotions) to the field force. Manufacturing may also use real time field information to reduce overproduction and the incidence of stale products. Additionally, Top executives often need information on market and competitors issues before they make big decisions. Real time information flowing from the field would enable executives to make decisions based on accurate information, which may enhance the quality of their decisions. Indeed the best source for top executives with regard to both market and competition watch is the field force. Conclusion Thus we have discussed about M-Commerce and the challenges that they impose on workers while on the move. We have also explored how m-commerce with its unique attributes can provide mobile workers with more freedom and support through minimizing non-productive time, enhancing interaction with other members and improving the quality of decisions. It is worth mentioning that m-commerce may result in some consequences that workers may not welcome. Perhaps the most immediate drawback of extensive use of mobile technologies by workers is the problem of â€Å"interaction overload†. Anytime and anywhere connectivity may becomes everywhere/all-the-time connectivity; which may result in the danger of users becoming â€Å"too connected†. But in the other hand, access to information at the point of relevance may make it possible for mobile worker to work smarter and to minimize their unproductive time, which may enhance their life / work balance.
