Roper Logan Tierney Model Activities Of Daily Living

Roper Logan Tierney Model Activities Of Daily Living INTRODUCTION In this assignment I will present a patient I have cared for during one shift on my placement ward. Using the Holland et al (2008) Roper Logan Tierney model of care which focuses on the activities of daily living a description of care received by the patient will be outlined. Any reference made to the patient is under pseudonym and referred to as Mrs Oni to protect the patient confidentiality according NMC Code of conduct (2008). To comply with guidelines set out by Department of Health (2009) full verbal consent was first obtained from the patient before any information was used in this assignment. My placement was in abdominal and orthopaedics surgical ward were patients were routinely admitted from accident and emergency and prepared for surgery and admitted after surgery. I have chosen a 33 year old female patient admitted to accident and emergency department and then to the ward with acute lower abdominal pain and later had non elective surgery for appendicitis. It was my duty under the supervision of my mentor, during this shift to monitor and maintain internal and safe environment, communicate and encourage patient to mobilise and wound management. The assessment tools utilised to create a care plan according to priority are those implemented and used by the trust. All activities discussed will be reflected upon as part of personal and professional development. CASE STUDY Mrs Oni is a married mother with two children under the age of ten. She is a health support worker and is employed full time. Mrs Oni complained that the pain started at the umbilicus region and then later the pain intensified at her right lower abdominal quadrant. When she was admitted upon examination by the general surgical team it was reported that her abdomen was tender and gardening. Other symptoms presented included constipation, nausea, fever and loss of appetite which all common to the condition. Patient had past medical history of being treated for urinary tract infection to rule out this as a possible reoccurring cause a urine analysis was performed and sent to microbiology testing and further analysis. Bloods were also taken to check for raised neutrophil (white blood cell) count. No previous history of abdominal pain, aggravating factors, patient felt relief when lying down with knees pulled up, presented no urinary symptoms, no alcohol consumption, and patient is not on any medication. On observing Mrs Oni she appeared anxious and was tired due to pain. When the patient was assessed using interview skills and attempting to form a therapeutic relationship with the patient it was revealed that Mrs Oni wanted to maintain a traditional African diet rich in fibre with lots fruit and vegetables, but found it hard to find time to prepare the meals and replaced it with unhealthy snacks while at work and didnt eat at regular meal times. She also revealed that she did not get much exercise and weight gained plummeted after her second child. Oxford dictionary for nurses state that the appendix is the short thin blind ended tube, 7 à ¢Ã¢â€š ¬Ã¢â‚¬Å" 10 long and is attached to the end of the caecum. The caecum is the first part of the large intestine according to Clancy McVicar (2002) appendicitis occurs when this tube becomes filled with faecal matter and or with other debris. It can also occur if the caecum is obstructed resulting in damage and blockage to the appendix. In both cases inflammation occurs which can cause rupture of the appendix and appendectomy surgery is required to stop other bowel and abdominal inflammatory conditions developing. I have chosen this patient because NHS Choices (2012) states that appendicitis is considered to be a common condition and that around 7% of UK population will develop the condition at some stage in the lives. It also states a lack of fibre in in diet can be a cause for the condition. I have also formed a good therapeutic relation with the patient. USING ROPER LOGAN TIERNEY MODEL Cronin Rawlings-Anderson (2004) cited Walker Avant (1995) who described practice theories as goal oriented actions. Llewellyn Hayes (2008) describes the model as an aid in assisting and measuring the patients ability to achieve independence at each stage of care. All 12 activities include, maintaining a safe environment, communication, breathing, eating and drinking, eliminating, personal cleansing and dressing, controlling body temperature, mobilising, working and playing, expressing sexuality, sleeping and dying. All activities according to Holland et al (2008) are used as a framework for the assessment, planning, implementing and evaluating process in the provision of care. Maintaining a safe environment is one example of how the activities can relate to patient care. Diamond (2011) uses the care setting as an example how a person human rights can become easily compromised. The Human Rights Act (1998) article 3 states that No one shall be subjected to torture or to inhuman or degrading treatment or punishment. This clearly illustrates that the environment in which a patient is care for should be maintained to ensure patient physical, mental and psychological wellbeing while also reducing the risk of infections. The Roper et al model of care is therefore a useful tool for ensuring that all patient needs are considered. Holland et al, (2008) also includes care for the internal environment that which is on a cellular level. This aspect forms a very important part of the recovery process for the case study patient Mrs Oni. ACTIVITIES OF DAILY LIVING FRAMEWORK OF CARE Chinn Kramer (2008) argues that a nurses action can help to improve patient experience by using their awareness and theoretical knowledge in situations, thus dislodging patient fears about situations that are new to them. The handover received for Mrs Oni described the patient sleep patterns throughout the night, stated the analgesics; paracetamol and tramadol prescribed for pain, discussed patient mobility, discussed patient intervention that was the physiotherapy sessions which were required for chest exercises, wound care discussed where surgical clips removed from the wound sloughing observed and surgical team notified as a result antibiotics now prescribed eight hourly and stated wound dressing needed to be changed and catheter to be removed. Although the assessment of the patient was received from a secondary source in handover the patient care still needs to be assessed in order to establish care priority for the patient. Holland et al, (2008) assessment is therefore the first stage in the process where the nurse uses communication skills to gather to begin planning care for the patient. Breathing On assessing Mrs Oni it was found that she was still feeling tired after getting a full nights rest. While listening to the patient it was observed that her speech was quiet and chest movements were irregular. The pulse oximetry machine was used to further assess the levels of oxygen in the patient. Correctly using the equipment making sure the patient was not wearing nail polish which can alter readings. The diagnosis with the reading confirmed that Mrs Oni was lacking oxygen. The normal range for the baseline measurements are charted out using the Glasgow Coma Scale used by the trust. It indicated that reading above 94% is considered within the normal range, Mrs Oni reading were 93%. It was decided that oxygen therapy was needed. A second intervention after the oxygen therapy was reassessed and had improved the patient breathing was made to prevent secondary infections the physiotherapists work with Mrs Oni, to teach her deep breathing exercises to avoid developing chest infections. The use of communication in assisting Mrs Oni by first providing a vomitus bowl and tissues as needed with the nurse explaining to patient why it was important to expectorate any excess sputum while giving the nurse the opportunity to inspect colour of sputum for signs of infection, according to Basford Slevin (2001) this reduces the chances of developing other complications. Mobility Mobility according to Perry Potter (2004) is affected by events and nursing intervention can improve body function and ability to recovery. NICE clinical guidelines (2010) to encourage hydration and mobility to reduce risk of venous thromboembolism (VTE). This condition according to Clancy McVicar (2002) is where clotting occurs in the veins and affects patients who have had abdominal surgery and experienced child birth. The surgical team did prescribe some prophylaxis treatment anti-embolism stockings which are referred to as TED stockings. However, the patient refused to wear them and has a right to do so according NHS Choices (2011) under the Mental Health Capacity Act 2005 which advises that a person has the right to voluntarily refuse treatment. On assessing the patient no real barriers to mobility was observed and with improvements on the patient breathing and fatigue levels, knowledge of psychological issues was required to further diagnose the patient. Using communication skills to form a therapeutic relationship as an intervention, Mrs Oni revealed that she was very worried about her children, she became tearful but discussing her children helped to remind her that she need to recover quickly to get back to her family and home. She was able to later agree to wear the anti-embolism stocking and began to attempt to mobilise without assistance. Another nursing intervention used to aid Mrs Oni in mobilising was to administer prescribed analgesics for pain management thus reducing the effects of the surgical wounds present. Personal Cleansing and dressing Mrs Oni had a wound had become infected and needed to take meropenem by intravenous infusion which according to BNF (2012) an penicillin antibiotic prescribed for  intra-abdominal infections, skin and soft-tissue infections. Mrs Oni stated she was not allergic to penicillin upon admission but the side effects from the drug were likely to be nausea, vomiting, diarrhoea, abdominal pain and headaches. According to BNF (2012) patients most at risk of developing anaphylactic reactions are asthma, eczema and hay fever sufferers. On inspection of the wound while changing the dressing it appear to be less exudate. On previous dressing change I was reported that there was some sloughing which is according to Perry Potter (2004) pg. 1278 are tissue cells that have died and have been removed from the body. Cleaning of the wound using the aseptic technique and new dressing were applied. Mrs Oni was then assisted with her personal hygiene needs and expressed that she was feeling much better. These actions taken will help to improve body image and reduce risk of prolonging the infection. Pain Although not mentioned in the handover it is still an effect experience after surgery. The tool used to measure pain is done using a numerical rating system with a scale rating pain from 0 to 10. Zero being there is no pain and ten being the highest value Indicating intervention needed. Perry Potter (2004) p.1274 definition of pain, subjective, unpleasant sensation caused by noxious stimulation of sensory nerve endings. This notion that pain is subjective is very true as each individual experiences pain in a different way according to Ewards R. article in Benzon et al (2005) pain can also be measured through observing behaviour. Mrs Oni did report pain and the prescribed analgesics were given as prescribed. Upon evaluation it was verbalised by Mrs Oni that she was in less pain four hours an hour later after administration. CONCLUSION The important aspect of the reflective process is to develop critical thinking skills which according to Jasper (2006) helps to develop the ability give clear rationales when making decisions. Reflecting using Gibbs et al (1988) cited by Bulman Schutz (2008) cycle where a series of reflective questions to be thoughtfully answered in retrospect which begins with the experience, a description of feelings, taking in account the positives and negatives, looking at the situation from different angels, what else I could have added to improve the outcome and finally the actions taken. Using the experience of caring for someone post-operative using the Roper et al, framework of care was a good teaching guide and created self-awareness of the process while helping to give a structured framework to gather knowledge in a way that was useful. I felt more comfortable and confident in discussing issues with my mentor on issues of care. The environment was very challenging but the framework help m e to focus and achieve my objectives. Evaluation of care using Llewellyn Hayes (2008) uses Huycke and Alls (2000) framework that encompasses all involved in the provision and receipt of care. The ward provides a comment card for patients, this way the immediate providers of care the staff receive instant and genuine feedback. This shows the patient experience is valued.

Harriet Jacobs, Slavery, The South, and the Civil War Essay

Harriet Jacobs remains one of the most important anti-slavery figures in American history. As a former slave turned author, Jacobs was very influential in shaping public opinion towards an anti-slavery sentiment. Jacobs was born into slavery in 1813. She would eventually escape into freedom in 1835. Her escape route would eventually lead her to Philadelphia where she would not have to worry about being returned to the south. (Most northern cities were sympathetic to escaped slaves) Upon moving to New York City, Jacobs would develop a personal relationship with a publisher named Nathaniel Parker Willis. Perhaps it was this relationship that inspired her to write her seminal work Incidents in the Life of a Slave Girl. Incidents in the Life of a Slave Girl detailed the horrible conditions that women faced in slavery. The stories were first published in the newspaper the New York Tribune. While the articles were well received at first, the graphic depictions of sexual abuse proved controversial and the serial was discontinued. Eventually, Jacobs work was published in book form. The book became an immediate sensation and significantly shaped an anti-slavery sentiment that surely fueled the abolitionist movement. While the north understood slavery was evil, the pure brutality of it was unknown to most. Jacobs work raised a much needed awareness. But why did the south embrace slavery in the way it did? There were a number of reasons why the south was a huge proponent of slavery. The most obvious reason centers on the enormous profits that the southern states were able to amass due to having free labor. In time, the south was eventually overly reliant on  slavery since it was a non-industrialized society. Without the presence of factories, modern machinery, and an industrialized production center, the southern states were reliant on human labor more than the north. And as previously mentioned, free labor in the form of slavery provided the mechanism for this backwards infrastructure. There were many issues that drove the notion of the south succeeding from the union. If there was a â€Å"final straw† that drove the southern states to succeed from the union, it was the election of President Abraham Lincoln. Lincoln had campaigned on an anti-slavery platform. When he was elected, he professed his assertion that no new states entered into the union would be allowed to be slave states. This led to several southern states succeeding from the union and to form the Confederacy. Obviously, President Lincoln sought to quell this succession as soon as possible. However, the tensions exploded on April 12, 1861 when the Confederacy launched an all out assault on the military base Fort Sumter in South Carolina. More than anything else, this was the inciting incident that led to an all out Civil War.   During the initial years of the Civil War, the south was seriously â€Å"hammering† the north as the north could not find a proper strategy to win the war. This situation nearly led to Lincoln’s defeat in re-election. However, Lincoln did win re-election and eventually found the right general in Ulysses S. Grant. Under Grant, the south was defeated and the Emancipation Proclamation was upheld. Slavery was no more in the United States. In the aftermath of the Civil War, the reconstruction of the devastated south began. One goal of reconstruction was to integrate the now freed slaves into society.  However, Lincoln’s assassination undermined reconstruction and African-Americans would remain disenfranchised in the south for an additional 100 years.

This book will end up being an important asset for individual and gathering study, Christian guiding, and marriage and family courses. Concrete Responses According to Kà ¶stenberger and Jones, God, Marriage, and Family, the western civilization is confronted with the need to define the meaning of the terms marriage and family (. p.15). I do believe that we as people got away from the design God intended for marriage and family. I never grew up with my father in the home and my parents never were married. My mother did marry but I never saw their marriage the way God intended for marriage and family to be according to His Word. The home was so dysfunctional that I developed emotional problems that carried into my adult life. As an adult I never knew I had problems until I got married myself. Even in my marriage it was not geared to what God intended. My ex-husband grew up with his father and mother in the home but did not learn about marriage and family God’s way. His father was very abusive to his mother and it was carried into our home. Both of us has two different beliefs on marriage and family. He believed that the wife has no voice and she

The Liability Of An Accountant - 1235 Words

THE LIABILITY OF AN ACCOUNTANT Recently, the question of liability has become more prevalent in the practice of public accounting. The AICPA (American Institute of CPAs) has been lobbying for liability reform in cases involving negligence or fraud committed by public accountants. So, being an accounting major myself, I wanted to write about the ongoing fight involving liability reform in public accounting. Contrary to some belief, accounting is not a â€Å"cakewalk† career. Accountants do not sit at a desk one-hundred percent of the time crunching numbers that always add up perfectly. In fact, accounting fraud is one of the largest scandals found today. When an accountant enters an engagement with a client, who are they liable to? Certainly not†¦show more content†¦If the accountant makes a false statement of fact, either knows the truth or recklessly disregards it, or if the client justifiably relies on the statement, the accountant would be liable for fraud. Accountants assume a large responsibility to their clients. They enter a contractual agreement, known as an engagement letter, and use engagement letters to minimize the risk they assume under the contract. Many engagement letters include memos limiting the recovery. Accountants expressly agree to do a project by a specific date, and imply that the work will be completed carefully. Like I said before, if an accountant breaches the contract, they can be found liable for damages. Another liability that I didn’t really mention was the trust that the clients give to their accountants. They are liable to keep the information confidential and to use it only for the client’s benefit. It is the accountant’s responsibility to be diligent with not only confidential client information, but also providing services with care, thoroughly, and to follow the ethical and technical standards provided to them by the GAAP (Generally Accepted Accounting Principles) and the AICPA. I n a case of Mattco Forge v. Arthur Young, there was a serious question of an accountant’s liability to client. In the 1980s, Mattco Forge began a lawsuit against General Electric, claiming discrimination against the company while they awarded GE contracts.Show MoreRelatedCurrent And Long Term Liabilities1504 Words   |  7 Pagesis to make profits, but understanding how to manage both current and long-term liabilities will insure an organizations success.

Remediation should render the land no longer contaminated and the effects of any important injury, or pollution of controlled Waterss that has occurred has been remedied, the suitably selected redress technique can in many state of affairss see the degree of taint reduced to such a degree that any considered important hazard is minimum, this does non nevertheless connote that all contaminations are removed wholly, in some state of affairss the contaminations are at such low degrees that they pose no hazard or that they are for good contained unmoved ( environment-agency.gov.uk 2004 ) . Remediation engineerings available Historically, the redress of contaminated land can be expensive and relies to a great extent upon procedures that are basically really proficient ( defra.gov.uk 2010 ) . Many of these procedures have involved heavy technology solutions, although considered to be really effectual, and in many instances, the merely feasible option, they have high environmental, societal and economic impacts ( clu-in.org 2012 ) . Categorization of dirt redress engineerings Soil redress engineerings can be categorised into four distinguishable wide categories ( Table 1 ) harmonizing to the cardinal rules involved in the remotion / containment of contamination ( s ) which can be farther sub-divided into unmoved and ex-situ techniques ( ehu.es 2012 ) . In situ clean-ups require no digging of contaminated stuff, in situ techniques are frequently preferable because of their lower application cost ; nevertheless, the general consensus is that these techniques take longer to make the preferable position and are more hard to supervise because of non-uniformity in intervention because of discrepancies in dirt stuffs ( DETR 1998 ) . Ex situ attacks ( digging of a contaminated country ) and handling it on site ( antique situ, on-site ) or transporting it to a distant site for ‘cleaning ‘ ( ex situ, off-site ) is by and large considered to be the more expensive option given the logistics of the operation, nevertheless, ex-situ techniques present the advantage of taking the bulk of taint forestalling farther spread ( iastate.edu 2012 ) . Table 1: Overview of both in situ and ex situ redress engineerings available, adapted from: ( defra.gov. 2010 ) . In-situ Technology Biological Physical Chemical Thermal Chemical oxidization and decrease i Electro – redress i i Enhanced bioremediation utilizing redox amendments i Blushing i i i Phytoremediation i Air Sparging i Biosparging i Stabilization and hardening i i Thermal Treatment i Venting i i Vitrification i i i Ex situ Biopiles i Slurry stage bioreactors i Chemical oxidization and decrease i Soil lavation and separation procedures i i Stabilization and hardening i i Thermal desorption i Incineration i Ex situ dirt vapour extraction i i Vitrification i i i Water and gas / vapour intervention i i i Biological redress engineerings Bioremediation uses micro-organisms ( barm, fungi or bacteriums ) to degrade organic contaminations ; bioremediation can be carried out both unmoved and ex-situ. The contaminations act as a nutrient beginning for the micro-organisms that break them down. Aerobic processes require a beginning of O, chase awaying C dioxide COa‚‚ and H2O H2O ( clu-in.org 2012 ) ( Figure 1 ) Figure 1: Conventional diagram of aerophilic biodegradation in dirt ( tamu.edu 2008 ) . Ex situ techniques include slurry-phase bioremediation, a procedure of keeping contact between micro-organisms and contaminations by adding H2O to contaminated dirts to organize ‘slurry ‘ ( iastate.edu 2012 ) . Other bioremediation techniques include ; Bioventing Injection of H peroxide ( H202 ) Solid stage bioremediation Landfarming Dirt biopiles Composting ( clu-in.org 2012 ) . Bioremediation is an economical procedure for a wide scope of applications of organic wastes. Many of the procedures can be handled in situ avoiding the demand to transport risky stuffs from site ( sa.gov.au 2005 ) . Physico – Chemical interventions Physical methods of dirt renewal are those that do non alter the physic-chemical belongingss of the pollutants accumulated in the dirt to be cleaned ( cieh.org 2007 ) . Physical redress techniques include simplified procedures such as dirt extraction and storage of contaminated dirts along with more complicated and technological techniques ( defra.gov.uk 2010 ) . In the physical procedures, the stage transportation of pollutants is induced. In the chemical processes, the chemical construction of the pollutants is changed by agencies of chemical reactions to bring forth less toxic or better dissociable compounds from the solid matrix ( unido.org 2012 ) . Physical redress techniques offer a cost effectual solution that can be concluded comparatively rapidly, and devour really small technology or energy resources ( eugris.info 2012 ) . Physical applications can be engaged both unmoved and ex-situ, and have the advantage that a wide spectrum of pollutants can be removed from the contaminated site and that they can be widely administered ( little, local sites ) ( unido.org 2012 ) . Physical-chemical interventions include ; Dirt Blushing Dirt lavation ( Figure 2 ) . Fracturing hypertext transfer protocol: //renewcanada.net/wp-content/uploads/2010/03/swallowtail2.png Figure 2: Dirt rinsing technique ( renewcanada.net 2010 ) Thermal interventions It is by and large considered that thermic procedures are the most dearly-won, nevertheless, a speedy redress clip is offered as compensation ( unido.org 2012 ) . Thermal redress involves the debut of hydrocarbon contaminated dirts into a het vas and retaining those dirts until they reach a unvarying temperature. Contaminants are heated by the thermic procedure, heat is applied to increase the volatility, to fire, break up, destruct or run the contamination. The hazard of let go ofing dioxins into the ambiance is an of import consideration and hence, runing temperatures are limited to 800A °F ( purdue.edu 2006 ) . Factors that influence the timescale of effectivity are the type and sums of contaminations present that scope from site to site, the physical size of the site and dirt stuff nowadays ( clu-in-org 2012 ) . Thermal techniques can be applied both unmoved and ex-situ, the rule advantage of unmoved techniques is that dirt can be treated without the demand to take and transport cut downing operating costs, nevertheless, unmoved techniques by and large take longer to de-contaminate a site and cost nest eggs are negligible. Ex-situ techniques involve the digging and remotion of contaminated dirts where they are exposed to high temperatures in intervention cells ; the cells contain contaminated media during the application. Although ex-situ techniques offer a decreased intervention clip, increased logistical deductions offset intervention costs ( clu-in-org 2012 ) . Thermal techniques typically include ; Hot gas taint Vitrification Injection of hot air Thermal Conduction Additional techniques are shown in tabular array? hypertext transfer protocol: //www.emis.vito.be/sites/default/files/data_sheets/migrated/schema % 20thermische % 20reiniging.PNG Figure 3: Diagram of thermic cleaning ( vito.be 2012 ) . 2.0 A critical appraisal of the effectivity of dirt redress techniques and the protection of groundwater 2.1 The Groundwater system â€Å" The largest available reservoir of fresh H2O † ( Environment-agency.gov.uk 2012 ) Water that is continually traveling through the environment is known as the H2O rhythm, nevertheless, most of the rain that falls will be soaked up by dirt, through the procedure of infiltration, H2O will soak farther down into the land and finally into underlying stones, this is known as groundwater ( groundwateruk.org 2012 ) . 2.2 The importance of groundwater 70 % of the planetary capacity of fresh water is groundwater, 30 % of this sum is found within rivers, lakes and watercourses, many of these rivers and lakes etc. are fed straight by groundwater, it can non be underestimated how much groundwater plays an of import function within the human civilization, groundwater is the line of life afforded to planetary wetland sites and a major helper to industry in a planetary context ( environment-agency.gov.uk 1999 ) . Whilst groundwater is by and large of good biological quality, it is invariably threated by contaminations, pollutants that seep through the surface and into the groundwater system, pollution occurs from diffuse beginnings when a pollutant is spread onto the land in the signifier of an applied agricultural pesticide for illustration and besides from point beginning pollution, where a chemical spillage has occurred for illustration. Some pollutants inputs will of course degrade or will be filtered out as the H2O flows through permeable stones, but on many occasions, the pollutants are relentless types and have to be subjected to typically dearly-won redress procedures ( groundwateruk.org 2012 ) . Figure 4: ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ( mfe.gov.nz 2007 ) . 3.0 Are dirt redress engineerings effectual at protecting groundwater? The mobility and destiny of contaminations that enter dirt are determined by a figure of factors ( postpone? ) , in order for a comprehensive and realistic site hazard appraisal to be carried out, consideration should be given to the nature and prevalent conditions in the dirts, including ; geology, hydrogeology, hydrology, contaminant geochemistry, geotechnics, ecotoxicology and microbiology, one time these have been decently addressed, a predicted behavior theoretical account of the contamination can be produced to help in the choice of the most efficient and cost effectual redress technique ( eugris.info 2012 ) . Relevant dirt and groundwater belongingss may include: Relevant contaminant Physico-chemical belongingss may include: Soil profile Contaminant concentration Dirt texture ( comparative proportions of sand, loam and clay ) Chemical speciation e.g. the valency or oxidization province of a metal Presence of mineral components such as clays, carbonates, phosphates, oxides and organic affair ( expressed as the fraction of organic C foc ) Solubility in H2O ( or other dissolver if a non-aqueous free stage liquid is present ) Moisture content Sorption ( soil-water divider coefficient Kd and organic carbon-water divider coefficient Koc ) Particle size distribution Octanol-water divider coefficient ( kow ) Bulk dry denseness Vapour force per unit area Porosity ( air-filled and water-filled ) Henry ‘s Law invariable Sorption capacity of the dirt Biodegradation pH and redox possible Nature of metabolites Microbial populations Vegetable consumption ( dirt to works concentration ) Elevation of H2O tabular array Weathering possible Groundwater flow way Diffusion coefficient in air Hydraulic gradient Diffusion coefficient in H2O Hydraulic conduction Viscosity ( gases and bluess ) Hydraulic dispersivity Viscosity ( non-aqueous stage liquids ) Table? : Factors act uponing the destiny and mobility rate of contaminations in dirt, adapted from ( eugris.info 2012 ) .

We will write a custom essay sample on Characteristics of Jack or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He just gives orders and expects people to obey for nothing. All this talk-â€Å" Jack shows how he is power hungry like a dictator because he is trying to make Ralph look like a bad chief in order for him to try to take the power away from him and get it for himself. (Motivations) Symbols That Represent Jack: 1. Long Hair During the duration of their stay on the island, all of the boys except for Piggy begin to grow long hair. This symbolizes their descent into savagery. Where the boys come from, (1950s England), it is unacceptable for a boy to have long hair; most males keep their hair short  and trimmed. In the world of the Island, everything is turned upside down, and what the boys would have once looked on at in disgust is now the norm. 2. The Beast After the murder of Simon, Jack begins to use the Beast as a manipulative trick to keep his hunters obedient. He tells them that the Beast is not really dead: No! How could we- kill- it(146). Adjectives that describe the personality of Jack: * Egoistic He seats himself as if he is a king on a throne and gives orders to others. The power is what he craves and the control. Manipulative he makes ralph look week by putting him on the spot infront of all the other boys asking if he was scared. * Corrupt Earlier in the novel, Jack claims that hunting is important to provide meat for the group, but it becomes clear that Jack’s obsession with hunting is due to the satisfaction it provides for his primal instincts and has nothing to do with contributing to the common good. * Animalistic/Wild – He is willing to shed blood and is not afraid to hurt someone or something.
