Understand the principle and the nature of static machines of transformer. Perform an analysis on transformers which their principles are basic to the understanding of electrical machines. ?  © MRM 05 Introduction ? ? ? ? A transformer is a static machines. The word „transformer? comes form the word „transform?.Transformer is not an energy conversion device, but is a device that changes AC electrical power at one voltage level into AC electrical power at another voltage level through the action of magnetic field, without a change in frequency. It can be either to step-up or step down. Transmission System TX1 TX1 Generation Station 33/13. 5kV 13. 5/6. 6kV Distributions TX1 TX1  © MRM 05 6. 6kV/415V Consumer Transformer Construction ? Two types of iron-core construction: a) b) C ore – type construction Shell – type construction ? Core – type construction  © MRM 05 Transformer Construction ? Shell – type construction MRM 05 Ideal Transformer ? An ideal transformer is a transformer which has no loses, i. e. it? s winding has no ohmic resistance, no magnetic leakage, and therefore no I2 R and core loses. ? However, it is impossible to realize such a transformer in practice. ? Yet, the approximate characteristic of ideal transformer will be used in characterized the practical transformer.

Brain Stimulation

The primary aim of this study was to determine the extent to which human MT+/ V5, an extrastriate visual area known to mediate motion processing, is involved in visuomotor coordination. To pursue this, the excitability of MT+/ V5, primary motor, and primary visual cortex was increased or decreased by the application of seven minutes of anodal and cathodal transcranial direct current stimulation (tDCS) in healthy human subjects while they were performing a visuomotor tracking task involving hand movements.The percentage of correct tracking movements increased specifically during and immediately after cathodal stimulation, which decreases cortical excitability, only when V5 was stimulated. None of the other stimulation conditions affected visuomotor performance. The researchers propose that the improvement in performance caused by cathodal tDCS of V5 is due to a focusing effect on the complex motion perception conditions involved in this task.This hypothesis was proven by additional ex periments: When testing simple and complex motion perception in dot kinetograms, it was found that a diminution in excitability induced by cathodal stimulation improved the subject’s perception of the direction of the coherent motion only if this was presented among random dots (complex motion perception), and worsened it if only one motion direction was presented (simple movement perception). The data suggest that area V5 is critically involved in complex motion perception and identification processes important for visuomotor coordination.The results also raise the possibility of the usefulness of tDCS in rehabilitation strategies for neurological patients with visuomotor disorders. Article 2 Environmental stimulation, parental nurturance and cognitive development in humans Martha J. Farah, Laura Betancourt, David M. Shera, Jessica H. Savage, Joan M. Giannetta, Nancy L. Brodsky, Elsa K. Malmud and Hallam Hurt 1. Department of Psychology and Center for Cognitive Neuroscience, University of Pennsylvania, USA 2. Division of Biostatistics and Epidemiology, Department of Pediatrics,Children’s Hospital of Philadelphia and University of Pennsylvania; Department of Epidemiology and Biostatistics, University of Pennsylvania, USA 3. Division of Neonatology, Department of Pediatrics, University of Pennsylvania and Children’s Hospital of Philadelphia, USA Developmental Science 11:5 (2008), pp 793-801 The effects of environmental stimulation and parental nurturance on brain development have been studied extensively in animals. Much less is known about the relations between childhood experience and cognitive development in humans.Using a longitudinally collected data set with ecologically valid in-home measures of childhood experience and later in-laboratory behavioral measures of cognitive ability, the researchers were able to test hypotheses concerning the effects of environmental stimulation and parental nurturance. A double dissociation was found: On one hand, there was a selective relation between parental nurturance and memory development, consistent with the animal literature on maternal buffering of stress hormone effects on hippocampus development.On the other hand, there was a selective relation between environmental stimulation and language development. The results primarily suggest that the same general dimensions of early life experience identified as important in animal studies of brain development are also important for humans. In particular, the relation between the composites measuring parental nurturance and later memory ability, which have no common-sense connection, is consistent with studies of experience and brain development in animals. The present findings thus provide an important bridge between the study of neurocognitive development in animals and humans.Secondarily, variation in the childhood experience of healthy humans bears a systematic relationship to cognitive development, and this relationship is more selective and specific than simply better environments predicting better development. Memory development is predicted by parental nurturance but not environmental stimulation, whereas language development is predicted by environmental stimulation, but not parental nurturance. Finally, these effects represent a possible mechanism by which socioeconomic status is associated with intellectual attainment. Article 3 MEG Study of Short-Term Plasticity Following MultipleDigit Frequency Discrimination Training in Humans Lichan Liu and Andreas A. Ioannides Laboratory for Human Brain Dynamics, RIKEN Brain Science Institute (BSI), 2-1 Hirosawa, Wakoshi, Saitama, Japan. Brain Topography, Volume 16, Number 4, Summer 2004 The researchers trained four right-handed male subjects to detect small changes in the frequency of 21 Hz electrical stimulation applied to digits 2+3+4 of the right hand for four hours. Before and after the training, magnetoencephalographic (MEG) signals were recorded whe n the stimulation was applied to digit 2-5 separately using a whole-head MEG system.Tomographic analysis was applied to the MEG data to track the evolution of activity over the entire brain every 1. 6 ms and evaluated the change for each digit before and after the training. In summary: (1) subjects improved in discrimination performance with training; (2) activations were identified in the left primary somatosensory (L-SI) and medial parietal precuneus (PCu) areas, but no systematic changes were observed in location and strength of activation of these two areas; (3) after training in L-SI, the 21Hzspectral power increasedfor digits 3 and 4 over the stimulation period, while the 10 Hz spectral power increased for digit 3 around stimulus onset and offset; (4) only digit 3 showed significant change of correlation between L-SI and PCu areas around the stimulus onset and offset, coincident with the increased 10 Hz spectral power. The results suggest that short-term plasticity is associat ed with changes in timing and interaction between cortical areas. DiscussionThe main finding of the first study is that cathodal tDCS applied to the left V5 improved performance in a visuomotor coordination task that encompassed both dynamic, high-resolution perception and selection of motion predetermined by a moving target. Stimulation of the primary visual cortex and the left motor cortex did not result in significant changes in performance, nor were the reaction times in the random dot kinetogram task significantly affected. These results suggest that tDCS indeed modified visual motion perception and motor performance.Common sense says that childhood experience affects cognitive development. Yet common sense does not say which psychological or brain functions will be affected by experience, or which specific aspects of childhood experience will exert an effect. The second study attempts to address these issues empirically with a unique longitudinally collected data set including ecologically valid in-home measures of early childhood experience and later laboratory measures of cognitive function. The effects found were strikingly selective and, in addition to their statistical significance, were substantial in size.In the third study, functional rather than anatomical short-term plastic changes in the brain induced by the frequency discrimination task were identified. After training, no new activated areas or expansion of activated areas or systematic increases in activation strength in any one specific area were observed. Instead, increased spectral power around 21 Hz in L-SI for both trained digits 3 and 4 for all 4 subjects was observed. Furthermore, for digit 3, increased spectrum power at 10 Hz in L-SI for all 4 subjects between map I and II around thestimulus onset and offset was observed. Conclusion After analyzing the above three methods of brain stimulation, one can come to the conclusion that the first study was found to have the maximum results i n term of invoking activity of the stimulated areas. The study stands out among the other two not just for its methodology, but also for its high reliability and accuracy. Hence, transcranial direct current stimulation (tDCS) can be considered to be the best method of brain stimulation.

Essay on the Freedom of the Press Essay

The Press, as identified with Newspapers, wields immense power in a democratic society. Dickens has called the Press â€Å"the mighty engine†. So great is its influence that some have called it the Fourth Estate. Napoleon used to say— â€Å"Your hostile newspapers are more to be feared than a thousand bayonets.† For, the press forms opinions, shapes movements and controls policies through well-informed criti ­cism. The most powerful autocrat is forced to take note of public opinion as reflected in a free press. That is why a regimented press is the instrument of autocracy, and a dictator deprives the press of its freedom. A free press is the symbol of a free people. An independent, well-informed press is a powerful check on arbitrary governments and irresponsible administrators. For newspapers are agents of the public, which bring to the notice of the people acts of injustice or oppression, or mal-administration that would otherwise have remained hidden away fr om public knowledge. They augur misgovernment at a distance and sniff the approach of tyranny in every tainted breeze’ (Burke). They exercise a constant vigilance on the rulers, which is salutary for all. Nowadays it is difficult for the press to be free. Either a newspaper is controlled by some financial magnates entirely and it has to voice their views or it is the mouthpiece of a party, and it must think as the party might direct; or it is under the thumb of the government and in that case its usefulness is reduced and independence compromised. For whoever controls it, necessarily limits its freedom by his own interests, i.e. calls the tune. In America, the great newspapers are in the bands of powerful financial syndicates; in England, they are in the hands of capitalists; in Russia they are mostly controlled by the government. But freedom of the press in each case depends on the way it reflects the will, the purpose of the people as a whole, in preference to that of any class or community or individual. The illusory or unrealistic character of the freedom of the press was seen during Great War. It is in such times of crisis that the voice of the people should be most clearly heard and not muffled. Yet it is then that newspapers are completely gagged. Most of these abuses might be checked to the advantage of all concerned, if the newspapers have freedom to criticise authorities and ventilate grievances. Indeed, no government can stifle the voice of the people but at  its own peril. The problem, therefore, is—how to ensure freedom of the newspaper. Legislation, of course, should guarantee the press against interference by the government; this goes without saying- But something more is necessary. The press under no circumstances should be forced to disclose the source of information or will be subservient to the government. But enjoins enjoys a corresponding duty on the part of the Press—that it should maintain strictly honest journalism and should not give any garbled report or prejudicial account. Independent-minded editors should have the right to ft free expression of opinions and unhampered publication of news, subject only to the limitation that they do not publish abuse and keep within the bounds of decorum. But real freedom of the press can exist only where a free people can function freely as in true democracy. It may be asked, why do we say there is no freedom of the press in England or America or India. The reason is that in these countries, the common people are in economic bondage. Governments are ruled by th e power of money and the press is controlled by owners in the interests of Big Business. In is, therefore, rightly claimed that in a Socialist country as the people become economically free, the government acquires an increasingly representative character. The journalists then can write freely and fearlessly. The best way to ensure freedom of the press is to publish all news from accredited sources, to allow free ventilation of opinion, to do away with all controls except in the interest of public safety or welfare. Freedom of the press should be a valued privilege and has to be safeguarded. It is a sacred right, which should be zealously promoted. Governments owe it to themselves to guarantee it from all arbitrary interference. Editors owe it to the public to maintain an honest and fearless attitude in favour of the people, against party or class interests. And the people owe it to their country to demand and defend such freedom as a priceless heritage.

Major differences between NEC3 & JCT SBC 2011 Coursework

Major differences between NEC3 & JCT SBC 2011 - Coursework Example The provisional sum for the JCT SBC 2011 contract is not mandatory like the case of NEC3 contract. The project manager is usually at pains to decide whether to adopt the discrepancies manifest in cost estimation for a project. The variations negate the principle of cost control in NEC3 contracts. The variations also compromise the control of overall project cost. Moreover, the costs associated with compensation events are separate from the initial tender price. 3.  Cost scrutiny The cost scrutiny should be made mandatory for both contracts because this allows easy cost evaluation. The large number of firms usually involved in a single mega construction contract requires long-supply chains. This implies that the identification of the costs involved is hectic. Consequently, cost accounting for the project takes a long time. The administration of cost pertaining to the company system increases the overall contract price. Adjudication of the contract cases is mandatory.4.  Ground ris kThe ground risk for the JCT SBC 2011 is higher than in the case of NEC3 contract. Caution should be taken with regard to the productivity and improvement in performance of the contract projects. Project management should be emphasized in the application of NEC3 contract.In both cases, a comprehensive program must be prepared prior to the start of the project. The contract should focus on the contingence events rather than the past. Programming for the contract is essential. The complexity of the project task must also be highlighted.

Analyzing The Self & Brand Personalities - Essay Example They understand that keeping their shares in the markets is linked to the level of their customers’ faithfulness. Such information is key to my growth and in defining my marketing strategy for developing a strong brand into the market. There are two theories describing this conceptual concept of the brand image and self-concept and these have an influence on the consumers’ choice and the brand preferences. These are the congruity theory, which entails the product cues that are involved and they usually use images to activate a schema that involves similar images. The second theory also referred to as the self concept theory seeks to explain that consumer behaviour research findings explains to us that consumers who perceive the product image are perceived to be well and consistent with their actual self-concept. For example, before purchasing a laptop computer or a mobile phone, I would consider going for strong brands that meet the four Ps of marketing. Moreover, this provides sufficient explanation to show that there is a congruence between the self-image and the brand personality. In fact, this is what increases the consumer brand relationship and the consumer satisfaction. For cases where there is a hig h involvement with the products, the relationship of the consumer brand quality will mediate an effect of satisfaction on the consumer’s brand loyalties. A good example is However, for the low involvement products the satisfaction will directly influence the loyalty of the brand. One of the most important issues in the market is brand royalty; this is because there is always a tendency of the consumers to purchase decisions by the brand images that have already been formed in their minds instead of the characteristics of the product itself or the original attributes. Presence of a unique brand is the key to a brand equity

LEGAL ASPECTS OF NURSING Case Study Example | Topics and Well Written Essays - 1000 words

LEGAL ASPECTS OF NURSING - Case Study Example 2. The nurses are negligent for delaying their medication documentation for such a long period of time as the next day. The fact that a medication is not documented endangers the patient of receiving too little or too much of the medications on subsequent shifts when other nurse have no way of knowing that there are missing entries in the records. 3. When the root of the problem or cause of the situation is evaluated the ethical principles which must be considered are patient safety first and foremost. Standards of practice should also be evaluated and the facility policy on medication should be evaluated to ensure that it is clear in all areas of medication administration. 4. If the case was heard in court the charges would likely be malpractice and negligence. Negligence and or malpractice can be defined as ‘the doing of something a reasonably prudent person would not do,’ it must be shown that the standard of care what deviated and that there were damages or injuries because of the negligence or malpractice (Understanding Negligence, 2012). The possibility of something dangerous or injurious to a patient due to medication errors such as those described is very strong and often nurses are taken to court for the same errors which end up causing injury to a plaintiff. Because there were no injuries reported or complaints from patients described it is less likely that the case would require court charges against the nurse. 1. The primary defendant in this case would be the original nurse suspected; however after the testimony and other nurse’s acknowledging their own wrongdoing and medication errors they should be suspended and held liable as well. The plaintiff could be the facility if they chose to bring charges against the nurse which is unlikely as this was cause negativity towards the facility. Most likely if charges were brought against the nurse they would stem from a patient incident. 2. The court would probably rule in

Leadership in Film - Essay Example Coach Norman Dale became Gene Hackmans comeback role, and Dennis Hopper earned an Oscar nomination for his performance as Wilbur "Shooter" Flatch. "Hoosiers is told from a nostalgic distance, and those allergic to corniness might best be advised to stay home," wrote a reviewer for The Washington Post. "But what do you expect in a movie about Indiana Corn is what they make there. And the movies enormous craftsmanship accumulates till you're actually seduced into believing all its Pepperidge Farm buncombe." Clearly, one man's corn can be another's inspiration. At sporting arenas around the country, it's not unusual for Jumbottons to play clips of Coach Dale firing up his Hickory Huskers with a pregame speech. New York Yankees owner George Steinbrenner has been known to compare his management decisions to those of Hickory High's principal, Cletus. Last year, Ron Hunter, coach of the IUPUI Jaguars, made his team watch Hoosiers before taking on number-one seed Kentucky in the NCAA men's basketball tournament. But not everyone loves Hoosiers.

Corporate law Essay Example | Topics and Well Written Essays - 1250 words

Corporate law - Essay Example Sarah, who bought a hotel from Nigel, later realized that the physical condition of the building, housing the hotel, was not in perfect condition as she had been led to believe, by her architect friend, is putting Nigel the proprietor of Colchester Suppliers through litigation. The financial performance of the hotel was also not, in accordance with what the hotel’s accountant had projected to her. Upon the revelation of these discrepancies, Sarah suffered a nervous breakdown, which she squarely blames on Nigel and is suing for responsibility. Sarah’s case against Nigel is a typical case of obligatory law, which integrates personal duty into the law governing such transactions between individuals and corporations. Nigel is not responsible for any wrongdoing, on his part because on the part of the financial performance of the hotel, the accountant made it clear to Sarah that the information presented was without responsibility, on his part, as the accountant. The fact tha t the accountant provided this information, when giving Sarah financial information pertaining to the hotel, shows that Sarah had an obligation to seek an alternative and independent opinion about the hotel’s accounts. This would have helped her make a better judgement of the hotel’s financial position and decide if it was worth her attention. She should not lay blame on Nigel, as the owner of the hotel, because it should have been that the account’s opinion would be bias, in favour of the hotel he or she has been catering for. The accountant’s actions could be partly due to the desire to portray the hotel in a positive light for retaining their position as employees in the event of a transfer of ownership. This transfers part of the blame to the accountant who should be held liable for their actions because the law under the obligations rule subjects them to the duty of telling the truth on facts and knowledge they are privy to (Golding & Edmundson, 2008 p148). Under corporate law, obligation to conform to social rules like telling the truth requires that a sanction be carried out against the accountant because of his/her actions. Obligations of this nature, under the law, make it a duty for someone to conform to some social rules that govern practices in businesses. These obligations are subject to a sovereign authority to obey where the command requires the conveyance of a will and awareness of the attached risk involved in suffering a sanction for non-compliance (Dimond, 2009 p180). Nigel, on his part, did not refuse to divulge information concerning the financial position of the hotel or opinion because Sarah never asked for it. If he had given his opinion, it can be held that he lied about the financial state of the hotel so He should be exonerated of any blame in matters relating to the finances of the hotel. However, at the same, it makes it his duty to ensure that his employee observed the appropriate moral conduct of confo rming to social rules because the accountant was in his employ. His failure to make it his duty and obligation casts some responsibility to him for his accountant’s actions. The obligation law casts more negligence on the buyer and the accountant because they did not do what was meant to be their duty under the law (Davies, 2011 p 318). Sarah consulted her architect friend, Liz, to assess the building the hotel was housed in, and this shows that she

How employers are dealing with the retirement of the baby boomers Research Paper

How employers are dealing with the retirement of the baby boomers - Research Paper Example However, it is important to note that knowledge is a concept that is multi-dimensional and its value can only be determined by circumstances, so employers are faced with a very complex problem in solving the problem (Datta, Guthrie, Basuil & Pandey, 2010). Management consultants have raised a number of concerns stating that baby boomers are presenting a very complicated problem to employers. Research studies reveal that employers are going to experience and impending mass exodus of employees and this will have a very serious effect on the operation of organizations than never before. The reality is that baby boomers have played an integral role in the success of organizations and they will be retiring in large numbers than never before. As baby boomers will are living their organizations, employers have been conducting careful examinations of the consequences of their exit and have formulate a number of necessary steps to ensure that there has been a smooth transition. By 2010, baby boomers were 48-66 years of age and were retiring from their employment positions. The consequence of the mass exodus was that the government’s entitlement programs and pension plans were strained. However, there was a sudden concern over vacant positions that were as a result of the mass retirements of baby boomers. In the United States, a recent research study revealed that more than 25 percent of businesses in the country have done very little with regards to planning for the effects of mass retirements of baby boomers. The study also predicted that it is expected that there will be significant changes in the workforce demographics of different industries (DeRue, Hollenbeck, Johnson. & Jundt, 2008). This is based on the fact that baby boomers are expected to retire in increasing numbers over the next twenty years. Researchers conducted a survey on 578 organizations in the United States and reported that only 33 percent of

First Person Paper about Esther Essay Example | Topics and Well Written Essays - 1000 words

First Person Paper about Esther - Essay Example However, the queen rejected the Kings Command and the king was furious. The king was advised accordingly that the queen’s behavior would make all women in the kingdom to despise their husbands. A royal decree was made and recorded that her royal position be given to another better woman as a lesson to all women and make men masters in their houses. The king was advised that a search be made for young beautiful virgins in the entire kingdom and be given beauty treatment so that the virgin who would please the king most would be made queen instead Vashti. I was living in the kingdom with my uncle Mordecai as exiles from Jerusalem. My uncle had brought me up as his own daughter since I had no father or mother and I was a young woman lovely and beautiful. When the king’s command was heard, I was also taken with many young women to the palace, under the care of Hegai his eunuch who kept his concubines. I pleased Hegai and gained his favor and this made him give me the best b eauty preparations. Meanwhile I kept my identity secret because my Uncle advised me so. My Uncle showed concern for me and he visited the women’s quarter daily to find out about my progress. ... He placed a crown on my head and made me the queen instead of Vashti. The king made a great feast for me for all his officials and servants, and he proclaimed a holiday in all the provinces and gave gifts generously. In the palace, I never disclosed my identity since I obeyed the advice of my uncle. My Uncle later discovered that people were plotting to eliminate the king and he informed me and I told the king about it. The matter was investigated and was found as true. The men were hanged and this was written in the chronicles before the king. After these things, the king promoted Hamah one of his officers and set him above all the princes and all servants who were commanded by the king to bow to Haman. However, Mordecai would not bow to Haman because he was a Jew and this made Harman very angry. He decided to destroy all the Jews in the whole kingdom and he set a date and month for carrying the plan. He sought permission from the king saying that the practices of the Jews were not in the best interest of the king and he promised to enrich the king’s treasury with silver and gold. The king allowed Haman to do with the Jews as he pleased and a decree was made in all the provinces in all languages and it was sealed with the king’s signet ring. The letters were sent to all provinces to destroy, to annihilate all Jews young and old including women and children on the twelfth month. Mordecai leant of this and he tore his clothes, sat in ashes, and cried loud in the city bitterly and he came to the king’s gate but he could not be allowed because of his attire. All Jews cried in all provinces with fasting, wailing and crying. My made and servants told me and I was distressed and I sent him

Amazing 7 Wonders of the World Essay Example for Free

Amazing 7 Wonders of the World Essay My name is Bshair, and I would like to tell you about one of the most amazing 7 wonders of the world I was given the opportunity to write about it. Not only because of the magnificent landmarks, but also because it has great history behind it, and it shows the roots of one of the most powerful empires the Incan Empire. Machu Picchu is the greatest Inca masterpiece. Incredibly daring and inventive, it was built on the most difficult, wild and inaccessible mountain area available. It is known world-wide not only for its impressive and unique ruins, but also for its unusual location on the edge of an abyss, from which one can appreciate the vigorous waters of the Urubamba river. I wonder how the Incas were able to carry the huge blocks of stone to the top of the mountain, we have no evidence that they used the wheel and build such a spectacular exponent of their wisdom and culture remains a mystery to this day. Of religious and military origin, the sacred city of Machu Picchu was enclosed by a wide wall. According to the archaeologist Alfredo, Machu Picchu can be divided into two major sections (the urban and the agricultural). Each part encloses two sub sections (the western and eastern) which are defined in relation to their topographic location. The agricultural section is divided into higher and lower ground. The high ground consists of five premises, the shrine of pile of stones marking a holy site and over 40 platforms. The low ground, meanwhile, comprises seven premises, four open areas and approximately 80 platforms. Some of the numerous agricultural terraces, which are placed in succession, are connected by stone stairways fitted in the walls, while others are linked by various set of steps forming corridors. The layout of the terraces and platforms is in perfect harmony with the mountains surrounding the site. Thus, the hillsides seem to be sculpted to harmonize with nature. There are 3 primary buildings in Machu Picchu they are the Intihuatana, the temple of the sun, and the room of the three windows. All the three rooms together are called the scared district of Machu Picchu. Legend tells that when a sensitive person touches their forehead to the Intihuatana stone it opens their vision in the spirit world. Finally, I Recommend people to visit this amazing place, I’m sure that they will be amazed and they will like what they see there, i would like to visit this amazing place my self some day, because it’s Something not to be missed.

A recent newspaper report Essay Example for Free

A recent newspaper report Essay The council had fitted a new toilet into Judy Weisss flat as part of a refurbishment. Ms Weiss noted that it looked good, but also complained that it smelled when the weather was warm. A workman was sent by the council to look at it, who then said they could not smell anything. No further action was taken regarding this particular issue.[S1] After some time, Ms Weiss then noted that a leak had started at the back of the toilet, where the floor and wall meet. It was miniscule at first and initially placed on the Low Priority list, before it then got worse to the point that the area always became flooded after the toilet was used, therefore becoming a High Priority problem. A professional was called again to look at it, and they turned off the water to stop the leak, but said Ms Weiss must use the toilet in the corridor instead. Ms Weiss complained that the toilet had been troubling her for two weeks now, and continuing leaks are resulting in emerging rotting on the skirting and stains on the floor tiles and hall carpet. She is now asking for compensation, and for everything to be fixed as soon as possible. This is a document to inform tenants of the councils policies about housing problems and how repairs to their homes are categorised, as well as advise tenants about how to report any problems which arise. This report has a mixed purpose to inform as well as to support readers on their case. Some positive points about the council are mentioned at the start of the article, but it mainly concentrates on highlighting negative points. It is positively mentioned that Westchester District Council came top in the Local Government rankings, mainly due to the recent refurbishment of all rented homes. There is a quote by Council Chief Amy Ayomola about how thrilled tenants are by the highly successful project. A spokesman from a local tenants association accused the council of window dressing and said that the upgrades are overdue and being done at the expense of normal repairs. It is said that the council is failing to meet targets for repairs, and that the council came 54th out of 72 in the rankings for tackling non-urgent repairs. CONCLUSIONS 1 The toilet smell in Judy Weiss home was dealt with correctly as per the councils repairs policy, with regards to Low Priority problems: there is a need for repair but this is not affecting the tenants ability to enjoy living in the property. This could include flaking paint, minor drainage smells or cracked tiles. 2 The start of the leak was initially correctly marked as Low Priority, due to its small size. However, as the leak increased so much to a point that the floors were being flooded and causing considerable damp damage in the area, it may have possibly been in the best interest of the council to deal with this in quicker time. 3 Since Ms Weiss had been contacting the council every week for the past six months with little response in return, more should have been done on our part to help her on time and not keep her waiting unnecessarily. RECOMMENDATIONS 1 In light of the problems highlighted by this tenants letter, the repairs policy should be properly reviewed and some amendments should be considered in order to improve it. 2 More investigation also should be done to find out whether these issues are truly a common occurrence for many more other tenants in Westchesters councils homes. A questionnaire would be a suitable method for this. 3 A letter of responsibility should be written and sent as soon as possible to the tenant, Judy Weiss, to acknowledge and apologise for her problems, as well as to inform her of what we can to do help and advise her of what actions she should make in future. 4 A response article should be written for the Westchester Gazette to let the public know the councils side of the story, and to portray itself in a more positive light.

Vanessas Maturing Process Theme Of Entrapment English Literature Essay

Vanessas Maturing Process Theme Of Entrapment English Literature Essay The theme of entrapment is a dominant theme in Margaret Laurences A Bird in the House. This is the theme that the author uses to shape most of his characters in the literary work. Vanessa Macleod is a protagonist in this story growing as the environment around her suggests. Margaret takes a Vanessa into an observational status where she would monitor activities around her. This would in turn affect her tremendously as she grows up. At the beginning, Vanessa is only twelve and the story tells of her growth till marriage with Chris. Margaret suggests to the reader that a person is changed significantly from his or her associations with the surrounding. As the story glides on the reader sees the many forms that Vanessa assumes in a bid to attain personal freedom. It is a quest for personal freedom although no character in the work attains it. This whole nature affects the way in which Vanessa grows. Remembrance Day is the story that starts at the beginning of the Margaret literary work. Vanessa is a teenager being influenced so much by hormonal changes in the body. En route to the church she observes the nature in which her father is in. According to her she felt pity for him although she did not really understand why this should be the case. As she was taught heaven is a beautiful place, probably, hence people should enjoy in the passing of their loved one. This is not the case and the imagination makes her engage her father into a conversation; I wondered what he believed in. I did not have any real idea what it might be. It is the nature of inquisitiveness of teenager children. Her father answers some questions that she asks him but they are not satisfactory, another demonstration of curiosity. It is easily seen how observable Vanessa is; He was frowning deeply and I could see the pulse in his temple à ¢Ã¢â€š ¬Ã‚ ¦ When he raised his head, he did not look uplifted or anything like that. He merely looked tired. This is the observation status that Margaret puts her protagonist in the play. This characteristic will be evident all through the discussion because it is the property that makes Vanessa make choices. The past affects the future as brought out in this play. They are written as reflections or discussions in the play. At the time when Vanessa discussed religion with her father, she would not understand his answer. Later he passed away from a short illness and while she was passing through her fathers belongings she came across a love letter and picture of a young French woman pp 107. Five years down the line she had grieved her father missing the companionship but is ignited by a single discovery that brings her fathers memories with nostalgia. It is at this moment that she understands that the past still lingers in the present. Imagination also plays an important role in Vanessas life and journey to growth. She was not going to participate in the activities of Remembrance Day owing to the fact that she despised military men. She did not understand the meaning of the day not until she had a brief epiphany of what death really is. He came to understand the meaning of this day by imagining what his dad felt while he watched his brother fade away in his death. Moreover the day too was important to her grandmother and by imagination she understood the pain of a mother. It was real when she lost her father. Vanessa learned the importance of the day when she found the love letter. The reflections of the past bring about moments of truth when the departed dwelt among their loved ones. Again she learns from the past and how the past affects the future. It is her journey towards maturity. It is also important to point out the relationships that Vanessa has. Some are distant without direct associations, while some are observational and others are interactive. In addition there is that solitary part which is marked by realizations and reflection, devoid of relationship. There are plenty of examples of these four categories of relationship. In Social Learning Theory of psychology studies, there are references of child growth in cognitive abilities through relationship hence the name social. In this breathe a great deal of learning that brings about maturity in Vanessa is through relationship. Some lessons are learned earlier while others are learned immediately the relationship hits a rock bottom. The latter is the most common in Margaret Laurence book. Vanessa greatly learns from consequences rather than having the intelligence to postulate in the future the results of certain actions. As seen with the relationship with Chris, Vanessa harbors important information that is crucial to her boyfriend; Chris was twenty-one. The distance between them was still too great. For years she had wanted to be older so she might talk with him, but now she felt unready pp. 140. Day in day out she tries to figure out how to communicate with Chris. All is late when Chris is admitted to a mental hospital. From this she learns the necessity to be open when she regrets having kept secret this information from Chris. She blames herself of Chris deterioration in health. It is the communication between partners that keeps relationship work out, a good lesson she learns. Grandfather Conner is a perfectionist but they had a distant relationship with Vanessa. There was no close contact between the two. However, through observation Vanessa was able to attain knowledge on the importance of being perfect. It is entrapment in discussion but learning from a distance. She understands this during t he sale of the brick house; She wanted to tell the new owners of the Brick house to trim their hedges, to repaint the window frames, to pay heed to repairs. She had feared and fought, yet he proclaimed himself in her veins pp. 191. Another aspect that contributes very much to her growth is the escape she has to reality. She exhibits resistance to a number of things in the story. At a tender age she attended the church just as her parents required. However at the time she was already curious of what she wanted to do with her life. As a result it is evident that she is always in conflict with her relatives. The interesting part is how she dealt with the resistance. Instead of showing it clearly, she actually blocked everything out. It is an attempt to independence. In particular during Sunday school lessons, she conceived stories in her mind with her as the main characters but without meaning; I was prepared, for the question was the same each week. I rarely listened in Sunday school, finding it more entertaining to compose in my head stories of spectacular heroism in which I figured as a central character, so I never knew what the text had been.. However, they were very important in passing time. In one way Vanessa knew what was important to him. She was interested only with certain things but ignorant of unimportant and uninteresting things. This way she was able to lean on a sided kind of growth and maturity. This form of resistance does not stop there. After her fathers death they move to the brick house where they lived with her grandfather. Occasionally she would get busy writing exaggerated adventure stories as a means to fulfill her thirst for personal freedom; I wanted only to be by myself with no one else around. She was so insecure to live on her own since the brick house represents strength where she may turn to. Even when Nanuk presents her with a relationship offer, she is still reluctant to be with him. In general Vanessas journey to maturity is an amalgamated package of life experiences with those who she came in contact with. Her relationship with her father made her indecisive in many occasions. Her father was indecisive as seen from the conversation he has with her daughter Vanessa. When asked about his thoughts about heaven, he gives thoughtless answers which affect Vanessa quite a bit. Down the line in her life, Vanessa meets with Chris. She is in a state of making a decision that is supposed to affect her life. However, she is unable to make the final decision whether to talk to Chris or not. Consequently, Chris is admitted in a mental institution. Her grandfather, Conner is a firm person and a perfectionist. He used to talk with a firm voice, raised all the time in a bid to make everything perfect. On the contrary he was able to analyze situations and make firm decisions about them. When Nanuk wanted to date Vanessa, he would constantly tell her that he was not fit for her. He stood with this decision till the end. Clearly Vanessa learned from her grandfather. When they left the brick house for new owners, she gave instructions on how to maintain the windows and hedges perfectly as they were. She reacted in a manner that her grandfather would. At another instant while talking to her brother, she engages in a conversation on how to name her dog. At one point she realizes her grandfathers voice echoes in her voice. When they moved to the brick house after the death of her father, Vanessa met her aunties who were soft spoken and humble. They had a loving character just like her mother. She immediately took their side and became humble, predictable and loving. In fact the story symbolizes her as a birch of logs in the basement. She is also similar to her mother. In the work it was evident that after a quarrel her mother and aunt would go in the kitchen and speak in whispers. In actual sense they would worry perpetually. This trait was adopted by Vanessa who would go about her worrying ways whisperi ng in inaudible undertones. Her grandfather also influences her in a number of ways. While she dated Nanuk, Conner would constantly resent him since according to him he was not to be trusted. In one way these were pointers thrown in here and there by grandpa. Although she loved him, she was taught not to follow love only in a person but to search for better qualities. They turned her into a self reflecting person who would ask rhetoric questions within, just to have better understanding of relationships. It was evident with Chris. In conclusion her journey to adulthood is one that is marked by influences through relationships between her and her immediate people who would throw pointers here and there for her. They nurtured her to what she became in adulthood. Work Cited: Laurence Margaret. A Bird in the House. Berlin: McClelland Stewart,2010.

Essay --

Effects on Politics at home The Vietnam War brought complete turmoil to the American society. It all started when President Harry Truman wanted to stop the spread of communism in the Middle East and Asia by promoting the United States as an anti-communism country and offering help to other countries that were also against communism. President Truman used the word containment to describe this act of stopping communism in his foreign policies. This containment policy transcended to the 1960s, when John F. Kennedy and his successor, Lyndon B. Johnson, were presidents. Kennedy won his presidency based largely on the fact that he promised to be more involvement in Vietnam (which was favored largely by the United States population) and the Cold War in general. Kennedy wanted to be more involved in Vietnam, and the Cold War in general, to preserve America’s power. With Kennedy and his team of U.S. Foreign Policy advisors, they believed to preserve America’s power they could help the development of Third World countries—mostly, in turn so they will not become communist countries. One of these countries so happened to be Laos, however, it soon fell to communism and Kennedy had to pull back forces. With the failure of the Bay of Pigs invasion and the back down in Laos, Kennedy believed that America could not withstand another failure; another hit that would diminish America’s integrity. This is what led to Kennedy’s involvement in Vietnam—for he could not take another defeat of it. Kennedy offered a huge amount of support for the Ngo Dinh Diem’s Government. However, Kennedy rejected continuous proposals on sending large amounts of American troops into Vietnam in fear of a full out war and a huge rate of deployment. Instead, Kennedy ... ...t about 2 billion dollars a month, leading America to experience deficits and inflation. Because of this de-valued U.S. currency, it lead foreign investors to invest in things more profitable—taking away a lot of America’s revenue. This lead to extremely higher tax rates, which also, threaten Johnson’s reelection. There were protests in the streets, angry civilians, too many soldiers overseas, and chaos among congress, that led to Johnson’s downfall. America was an absolute turmoil, and because Johnson relied too heavily on his advisors—which often had many different opinions—he did not know how to control the chaos. When reelection time came around, Richard M. Nixon won in a landslide with the promise of ending war in Vietnam. By 1969, Nixon had instituted Vietnamization. This policy ended America’s involvement in the war and lead to a more stable America.

Freedom is Not Free in Bread Givers Essay -- Bread Givers Essays

Freedom is Not Free in Bread Givers  Ã‚     Ã‚  Ã‚   Anzia Yezierska in Bread Givers and "Children of Loneliness" explores the theme of reconciling assimilation to American culture and retaining her cultural heritage. "Richard F. Shepard asserted in the New York Times that Yezierska’s people†¦did not want to find themselves. They wanted to lose themselves and find America" (Gale Database 8). Rachel and Sara, the main characters, move ahead by employing the America motto of hard work will pay off. The problem for both is losing their Jewish identity in the process. Yezierska, like the female characters, experienced the loneliness of separation from the Jewish people when she rose above poverty. "I am alone because I left my own world" (Ebest 8). She explores this issue repeatedly in her work trying to find a solution to a problem with no easy answer. In order to obtain religious, social, political, and equality 23 million Jews immigrated to America during the years between 1880 and 1920 (Chametzky, 5). Anzia Yezierska wrote about her experiences as a poor immigrant in her fictional work becoming a voice of the Jewish people in the1920s. She struggled to obtain an education that allowed her to rise above her family’s poverty and gain a measure of autonomy. Rachel and Sara, the female protagonists, mirror the author’s life going from struggling immigrant to college graduate. Yezierska uses her own experiences to portray the Jewish immigrant experience with a woman’s perspective.

Wal-Mart?s SMART Inventory System Essay -- essays research papers

After extensive last minute digging, I finally found a manager who trusted me enough to supply me with the name of the inventory system that is used. Unfortunately for me this is all I could uncover from my employer, but it is a start. Wal-Mart uses the SMART system. Because of the way it is spelled I can only assume that it is an acronym. I have been searching for over an hour on Google.com and finally produced some meager results, but here they are. Background From the results produced, I am at the deduction that SMART is not an acronym after all. SMART is basically a tracking system, it keeps track of all our inventory, the on-hand counts, and can automatically reorder product that is low or empty. As stated last week, most interaction with the SMART system is through the Telxon. Just to recap, the Telxon is a 900 MHz wireless handheld terminal equipped with a barcode scanner. When a barcode is scanned, almost instantly the item number, a short description, on hand counts and amount on order are displayed. The technicalities are a mystery to me but I can only assume that the Telxon is linking to the SMART database to retrieve all of this information. All from a simple thing like a barcode which is just a set of numbers that are unique, like a primary key. Strengths of SMART The actual database has to be enormous. There are so many products that the Wally keeps track of. All of which must be in the same database because products we don’t carry will still scan and give...

Emotional Connection and Its Relation to Physical Intimacy or Sex Essay

Majority of women view sexual relationship with valued commitment. They do not allow themselves to be persuaded by their partner who believes that sexual intimacy is part of having a relationship. On the other hand, old-fashioned and modern day women acknowledge the belief that sexual relationship is much persistent within marriage life. This could be true since emotions flow and desires could be much prevalent in the intimate moments of married couples. However, this assumption can be a predicament, finding that intimacy within marriage somehow unpredictably vanishes, and consequently unlit the once flaming emotions. In western cultures and highly developed countries, it is publicly acknowledge and as a normal happening to observe teenagers already sexually aware, accepting that having sexual relationship is a customary expression of love. In fact, sexual orientation is part of the educational curriculum, embarking on the sexual awareness of teenagers at their early age. However, sexual awareness does not pinpoint much the linkage of keeping a happy marriage which is seemingly less emphasized in the sex education, discussing the development of sexual maturity. Either in marriage or in a platonic relationship, one of the important elements that should be present is emotional connection. However, experts believe that the key to successful relationships within marriage lies on adding the aspect of emotions to physical intimacy or sex. Coping or surviving an affair is determined by the sexual intimacy as partly the emotional means. Marriages come to an end because one or both parties are not emotionally attached to each other. They do not see their spouse as a partner in life but as a different individual which tends to be obsolete over time. This research paper will discuss and examine how relationship of couples is survived by several factors within their married life, relating how the effect of emotional connection to physical intimacy or sex is significant features. The review of several literatures and other information is the method used throughout the examinations and findings. Literature Review Overview In the United States, the common causes of divorce are found by experts to be purely emotional, rather than the usual infidelity of a partner. Vis-avis infidelity is also causal to several emotional disturbances, like failure to achieve sexual satisfaction can be disappointing and may cause one party to look for another sexual partner. The troublesome underpinning of failed emotional connection to a partner then becomes a baggage of couples right through their married life. Emotional connection is very crucial in every relationship, specifically marriage. This is why it is important for the couple to get to know each others emotions before deciding to exchange vows as the next level of commitment. Emotions could be the result of openness according to the individual liking or disliking that can be connected by simple understanding, agreement and appreciation (Paulsen, 2008). Sadly, emotional connection gradually disappears as the married life of couples matures. The intimacy that is required to make their marriage strong is displaced on the side, as couples seem to have separate lives within the home setting. When simple differences set in, their individual â€Å"baggage† comes in which initially ignite the unfulfilled emotions that cry out loud as a hostile ground of resentments. The conflict begins beyond disagreements and feeling of neglect, resulting to resolve at the option of divorce. Emotional connection is important in the survival of marriage, enabling couples to iron out differences and work out a solution without parting ways. The convergence of emotional attachment allows couples to make compromise in order to set aside the beliefs that separation would resolve the disagreements (Johnson, 2008). Thus, several factors must be established as the converging point of emotional connections. Importance of Emotional Intimacy in Marriage According to an article written by Shruti Paulsen (2008), creating emotional intimacy in marriage is vital to its survival and success. He likened married life to traveling on a ship with two pilots. At first, the two pilots know what direction to take as well as their destination. However, as the trip goes on, one of the pilots decides to shift the direction to the surprise of the other pilot. In a sense, this is what happens to marriage. In the first few years, the couple has a shared direction and goal. In order to establish emotional connection, it is important for couples to communicate with each others directions. Human culture has the notion that it is bad to be dependent and is a sign of weakness. The truth of the matter is that being emotionally connected with another individual is not. In fact, it provides some sense of security and safety. The basic tenet of the attachment theory is that being apart from another individual can be a traumatic experience (Johnson, 2008). On the other hand, the absence of emotional connection puts into jeopardy an individual’s need for security. Without someone to be emotionally connected with, there is a reason for an individual to panic and become worried. Being emotionally disconnected can play a crucial role in married life as well as in the life of partners. It develops into mistrust of a spouse of their partner (Johnson, 2008). Emotional connection paves the way for couples to develop a deeper understanding of themselves. Establishing intimacy requires sharing of feelings, thoughts, and beliefs. There are various factors that can affect the ability of couples to become emotionally connected to each other. Rearing of children and hectic schedule at work can contribute to the loss of emotional connection and intimacy. Aside from their failure to communicate with each other, there are other factors that can also lead to emotional insecurity such as low self-esteem, childhood experiences, past rejections, and failed relationships. When emotional connection is lacking, marital problems can set in. One spouse views their problem differently than the others (Marriage Quest. Org, 2007). Treatment Issues Warning Signs of Marital Problems When emotional connection is lacking, marital issues can develop some vital signs of marital problems, such as (1) feelings of isolation; (2) increase in arguments or negativity; (3) lack of affection; (4) increase in anger, hostility, and/or sarcasm; (5) avoidance of each other; stonewalling; (6) mistrust. Unfortunately, majority of couples do not possess communication, anger management, commitment, conflict resolution, and intimacy skills (Relationship Institute, 2004). According to Relationship Institute (2004), a study conducted by Dr. J. Gottman from the University of Washington has found the following ‘Four Signs of Relationship Breakdown’: ? Criticism is more than a complain when a spouse finds fault in their partner and attacks the personality and character of the other. ? Contempt shows intention of a spouse to insult or psychologically abuse the other. ? Defensiveness shows unwillingness of a spouse to listen to what their partner wants to say out of fear of being attacked or hurt by the other person. ? Stonewalling is for the spouse to completely ignore or make distance from the other. The Relationship Institute (2004) further cited that a similar study of Dr. Markman and Dr. Stanley from the University of Colorado has described the ‘Four Indicators of Relationship Breakdown’, as follows: ? Increased negativity during interactions of couple shows increased complaining and criticism of each other. ? Invalidation of couple does not show any interest in understanding each other’s point of view. ? Negative Interpretation occurs when one spouse does or says something neutral or positive, but their partner perceives it as hostile or negative. ? Avoidance and withdrawal shows the disagreements. Lack of emotional connection can likewise lead to look for a substitute for the lost intimacy. The substitute can be sexual in nature, such as a sexual partner (infidelity), sex over the phone, pornography, nightlife related to sexual mingling, internet blogging, chronic masturbation, to name a few, or non-sexual in nature, like sports activities, gambling, shopping, pets, community activities, among others. Therapists view these conditions as a disease or addiction, in which sex therapy is suggested to determine the underlying problems (Marriage Quest. Org, 2007). Another potential problem that may arise as a result of the absence of emotional connection is emotional affairs. Having an emotional relationship with another individual is as dangerous as having a physical affair. In marriage where emotional connection is conspicuously absent, one of the spouses finds emotional intimacy through circle of friends. The spouse finds ease, safety and comfort in confiding with another individual, wherein the emotional bond between the couple can become blunt which may jeopardize the marital relationship (Wasson, 2007). Most spouses deny speculations that they are emotionally attached to their friend. In which case, the spouse do not have an idea on what their intimacy with their friend or another person can do to his or her marriage life. While the attachment may not be obvious on the outside, there is however an underlying â€Å"physical chemistry† which can heighten the emotional bond between the individuals involved. The person with whom the spouse has an emotional intimacy with can either be an old friend or a co-worker. It can also involve an individual whom the spouse met through online chatting (Wasson, 2007). Eventually, this individual could transform as the spouse’s primary source of emotional strength. As this develops, the spouse would slowly feel that the friend or co-worker understands them better than their spouse. This would become a major marital problem because it would reach the point that the spouse would keep the conversation a secret to their partner. The spouse would then feel betrayed or deceived by their partner who would bring about a fracture or barrier in their marital relationship (Wasson, 2007). A certain John Gottman who has been undergoing research for more than 18 years, revealed that there are four potential contributors to unhappy marriage namely defensiveness, criticism, contempt, and stonewalling. Divorce is a potential end result due to the couple’s lack of communication. It was found in a study involving 130 newlywed couples that (1) lack of emotional connection was lacking as reflected in the husband’s rejection of the influence of his wife, (2) the negative feelings of the wife during conversations, (3) the failure of the husband to weaken the low-level negative effect of his wife, and (4) the absence of physiological soothing in the male (Levine et al, 2005). Studies have also revealed that the negativity of their wives has an adverse affect on the husband. This is evident when they withdraw from conversations raised by their wives’. As a result, the relationship satisfaction of the wife declines. The couple then undergoes a negative cycle wherein a high degree of negativity from the wife leads to higher degree of withdrawal from the husband (Levine et al, 2005). Infidelity Having an emotional affair is also known as emotional infidelity. Although there is no physical component that might be involved, emotional infidelity is an act wherein a spouse invests love, time, and attention to another person other than their partner. Components of emotional intimacy are present such as sharing, understanding, companion, self-esteem, and close relationships. According to a 2003 study, 57% of women and 44% of husbands revealed that they were emotionally connected to another person without involving intercourse. The study also revealed that women are more prone to emotional infidelity than men (Piercy et al, 2005). Infidelity refers to the â€Å"breach of a contract of sexual exclusivity between two individuals† that is dating, being married, or committed to each other. Recent definitions have expanded to having sexual relationships with another individual aside from the partner. It may also involve cybersex, pornography, physical intimacy, or emotional attachment with another person which jeopardizes the primary relationship. Infidelity may also involve issues which are connected to time, energy, and resources in order to maintain the other relationship (Piercy et al, 2005). According to statistics compiled by the National Center for Health Statistics from the 1980s to the early part of the 1990s, approximately a third of marriages end up as a failure in the first 5 years and about fifty percent to two-thirds results to divorce. Several studies reveal that a marriage which started with love, care, affection, sense of humor, commitment, and optimism usually results to satisfaction. This was reflected in a longitudinal study involving 95 newlywed couples who perceived that the marital bond between partners would stay married or divorced within the first five years of married life (Levine et al, 2005). Effects of Infidelity Emotional infidelity has a significant effect on the lives of couples and families. It transcends in the couple, family, as well as in the social network of the couple. Upon the discovery of the affair, the couple needs to make a decision whether to continue the relationship or part ways. To the offended spouse, they would become angry at their partner for betraying them. Eventually, they would lose their trust in their partner for their deception (Piercy et al, 2005). Aside from anger, the offender spouse may also become suspicious of their partner, having mistrust of the same cheat. They may continuously inquire about the whereabouts of their spouse. In return, the involved spouse may need to report about their activities and may be judged by their partner. Psychologically, emotional infidelity may lead to guilt feelings and loss of self-esteem. The involved spouse may develop the need to protect their partner from being hurt as a result of their deception. Consequently, this may hurt the couples’ chances of working on their relationship. They would develop fear of resolving some difficult issues as well as feeling unsafe communicating with one another (Piercy et al, 2005). Infidelity may also bring about physical effects. The combined factors of stress, agitation, and exhaustion can result to health issues for both partners. Likewise, the involved spouse may place the primary relationship at risk with the threat of sexually transmitted diseases such as HIV and herpes. Some STDs can be a lifelong suffering which could have a significant impact on the life of the couple and their families (Piercy et al, 2005).

Dettol Marketing

Dettol Brand is strongly positioned in the market as â€Å"The best killing germs antiseptic†. It is market leader and it has strong credibility and trust, it’s a top of mind in its category and it has two value propositions: functional (protection for germs and killing wounds) and emotional (love and care from a mother taking care of her child). This emotional campaign was supported with a strong advertising campaign where a mother is shown reading a letter from her son who is in a boarding school, the mother wasn’t worried about her son because he was away from home because she felt he was safe with the protection of Dettol.The campaign helped in making emotional connection with consumers and people remembered the campaign even long after it was discontinued. Everyone knows Dettol as a brand who helps you protect your family’s hygiene and health, it was a â€Å"must-have† product for every household in United Kingdome and India. ACNielsen made a s tudy that backed this theory up stating that Dettol is in the top rank of popularity as one of the most trusted brands.But as it is strongly positioned, everyone thinks about Dettol as a synonymous of â€Å"germ killer† and â€Å"antiseptic†. When they tried to introduce several new brand extensions to the market it was very difficult to change people’s mind about seeing the brand for other purposes or uses instead of just antiseptic. Most of these brand extensions didn’t have the expected results and had very poor sales level, for example: Medicated plasters, shaving cream, talc, floor cleaner and mouthwash: they didn’t achieve the expected results in sales and market share was not significant. They found competition in those categories, brands that were already positioned in the market and Dettol couldn’t compete. The only product that was successful in sales was the soap and liquid soap, probably because these products are strongly associ ated with germ killing. It achieved 44% of value share in liquid soap.It was very difficult and maybe inappropriate to introduce all these new products extensions with the Dettol name, maybe they could have used another name because the â€Å"Dettol† brand was so associated to â€Å"antiseptic†, that it became generic among the target market. For example, it would be similar to say that â€Å"Kleenex† wants to sell shampoo. People just wouldn’t accept it and it would be very difficult to change this strong brand association to one specific concept or product.

Applying the VRIO Framework Essay

1Barney and Hesterly (2006), describe the VRIO framework as a good tool to examine the internal environment of a firm. They state that VRIO â€Å"stands for four questions one must ask about a resource or capability to determine its competitive potential: 1. The Question of Value: Does a resource enable a firm to exploit an environmental opportunity, and/or neutralize an environmental threat? 2. The Question of Rarity: Is a resource currently controlled by only a small number of competing firms? [are the resources used to make the products/services or the products/services themselves rare?] 3. The Question of Imitability: do firms without a resource face a cost disadvantage in obtaining or developing it? [is what a firm is doing difficult to imitate?] 4. The Question of Organization: Are a firm’s other policies and procedures organized to support the exploitation of its valuable, rare, and costly-to-imitate resources?† What types of resources should we evaluate (e.g., what types of resources lead to a competitive advantage)? 1) tangible resources, 2) intangible resources, 3) organizational capabilities. Reputation with customers for quality and reliability Reputation with suppliers for fairness, non-zero-sum relationships Organizational Capabilities Firm competences or skills the firm employs to transfer inputs to outputs Capacity to combine tangible and intangible resources, using firm processes to attain desired end. Examples Outstanding customer service Excellent product development capabilities Innovativeness or products and services Ability to hire, motivate, and retain human capital Applying the VRIO framework. According to the VRIO framework, a supportive answer to each questions relative to the firm being analyzed would indicate that the firm can sustain a competitive advantage. Below is an example of how to apply the VRIO framework and the likely outcome for the firm under varying circumstances. Applying the VRIO Framework—the value and rarity of a firm’s resources If a firm’s resources are: The firm can expect: Not valuable Competitive Disadvantage Valuable, but not rare Competitive parity (equality) Valuable and rare Competitive advantage (At least temporarily) Then, if there are high costs of imitation, the firm may enjoy a period of sustained competitive advantage. Costs of imitation increase due to some combination of the following: 1) Unique Historical Conditions (path dependence; first mover advantages), 2) Causal Ambiguity (links between resources and advantage foggy), 3) Social Complexity (social relationships not replicable), 4) Patents (double-edged sword since period of protection eventually runs out). Applying the VRIO Framework, integrating the notion of Inimitability If a firm’s resources are: The firm can expect: Valuable, rare, but not costly to imitate Temporary competitive advantage Valuable, rare, and costly to imitate Sustained competitive advantage (if organized properly) Organized properly deals with the firm’s structure and control (governance mechanisms—compensation, reporting structures, management controls, relationships, etc). These must be aligned so as to give people ability and incentive to exploit the firm’s resources. Summary of VRIO, Competitive Implications, and Economic Implications Valuable?

EXECUTIVE SUMMARY This paper is based on the case study Organizational Transformation in a Health Care Clinic where focus, is the many organizational transformational issues that take place during an organisational development and transformational change of the Health Care Clinic. According to Anderson and Ackerman (2001:39-40 & 50), transformational change is defined as a â€Å"completely new way the organization and its people see the world, their customers, their work and themselves. For organizational change to be successful the procedure would require changes that would affect employees’ behaviour, how they think and the organization’s culture thus raising many transformational issues such as leadership issues, communication issues, training and development issues, and cultural issues.

INTRODUCTION:ORGANISATIONAL TRANSFORMATION can be defined as â€Å"a fundamental shift in the way business delivers value to its customers and stakeholders resulting in dramatic change strategy, processes, technology and utilisation and management of human resources to meet the needs of the global economy†. ORGANISATIONAL DEVELOPMENT is a system wide application and tra nsfer of behavioural science knowledge to the planned development, improvement and reinforcement of the strategies, structures and processes that lead to organisational effectiveness. Many organizations of today go through changes because of circumstances, wanting to become more developed and/or advanced or simply because of wanting to move with the time.Management of the health care clinic initiated an organizational development programme because of problems originating from the application of modern technology to the jobs of medical technologists. It was discovered that employees of the biochemistry department were greatly dissatisfied because of their feeling of having their skills underutilized, having cultural differences with other staff members, having communication barriers and not having job challenges present. The organizational development staff and the manager agreed that job redesign should take place to bring more autonomy, control, feedback and meaningfulness to the w ork for the employees of the clinic.Over a period of two years evaluation of the results by the organizational development staff found that job characteristics and satisfaction declined for both groups that were involved in the transformational change process. Changing environments of an organization has effect on the organization and the organization’s environment thus creating many transformational issues. Transformational issues include leadership issues, cultural issues, communication issues, cultural issues and training and development issues. 1. 1. OBJECTIVES: 1-To identify the organizational transformational issues that are involved in the change in the health care clinic 2-To evaluate change implementation and intervention strategies at a health care clinic. 1. 2. METHODOLOGY:The researcher in the context of this case study has opted to use the phenomenological approach as opposed to a positivistic approach (Collis and Hussy 2003). Triangulation-â€Å"the use of more than one method or source of data in the study of a phenomenon so that findings can be cross checked† Bryman (2008 pg. 700) Triangulation method of data collection will be used collecting qualitative and quantitative data from both primary and secondary sources for example using unstructured questions and interviews. A variety or literature, theoretical and analytical tools and techniques will be used. The research conducted being a case study the data collection will be consequence on the evidence as suggested in the case study. Random sampling s suggested by Saunders et al cannot be validated, in that for quantitative research the sample size must be of at least 95% in order to obtain realistic or quantifiable data and it may be dangerous and less accurate to do otherwise. 2. 0. LITERATURE REVIEW The core issues which will guide the facilitation of policy development, plans and programs for the organisational will include the under mentioned factors: Lewin’s(1951) fo rce field analysis demonstrates the two key external forces that push organisations into change situations but counteracting, resisting forces are often arisen from inside organisations when the changes are attempted and that change occurs when the driving forces out number resisting forces.This force field is propagated on the idea that social situations can be seen as equilibria that are periodically disturbed when changes to the situation are attempted. The concept of change as modification of these forces keeping a system’s behaviour stable. The two groups of forces are those striving to maintain the status quo and those pushing for change. A state of ‘quasi-stationary equilibrium’ as coined by Lewin(1951) is achieved when both sets of forces are almost equal and current behaviours and attitudes are maintained. FIG. 1 BELOW REFERS. Kurt Lewin (1951) identified three stages of behaviour modification in a simplistic change management model is seen in the table 1 below. LEWIN(1951)THREE STAGE MANAGEMENT TABLE. (TAB. ) UnfreezingIs concerned mainly with selling the change and provides a motive for groups and individuals to change their attitudes, systems, behaviours values and structures. The unfreezing stage will be greatly accelerated if it is recognised that the need for change is immediate, clear and the survival of the organisation depends upon it. MovingIs concerned with recognising what the new attitudes and desirable practise, norms and behaviours should be and communicating it and encouraging others in the organisation to embrace and own it as new job requisites. This aspect can occur through assimilation and exposure to new concepts or from individuals with different perspectives. RefreezingThis stage is the final and stabilising stage of the change implying reinforcement of the new behaviours.Evoking positive reinforcements such as rewards and praise. For negative reinforcement such as sanctions for indiscipline or deviant attitu des. Source:Mullins,Laurie J. (1997) Management and Organisational Behaviour 9th. Edition. FT/Prentice Hall . Again, Lewin(1951) suggested that for change to be successful there must be group activity. Unless group norms are transformed there will be no sustenance to individual actions and without reinforcements change can be short-lived. Employees are beginning to accept that the time has come for change and the changes must be made so that the organisation can remain viable. Schein (1988) model of change outlined the pivotal role of the change agent.Schein (1988) delineated each stage of Lewin’s (1951) model by expressing the dynamics of individual change and how imperative it is for change agent to manage these changes (see table 2 below) the change agent can be seen as the coach, facilitator and motivator assisting individuals through the change can be seen as the coach, facilitator and motivator assisting individuals through the change. According to Schein’s(1988) model the first stage the change agent assists with motivating the individual by disconfirming their behaviours, attitudes and performance. Stage two emphasises the need to get employees to perform tasks differently and actually engaging belief that changing norms and working habits can effectively improve their performance.At Stage three the change agent helps the employee to change his thought patterns by integrating new and well defined behaviours. Self conceptualisation and reinforced performance standards are confirmed. Schein (1988) believes that none of these stages are susceptible to self management but need the intervention of change agents. In furtherance, Cummings and Worley (2005) planned change concept outlined how change can be implemented in organisations. This action research model places heavy emphasis on gathering and diagnosing data prior to action planning and implementation and on assessment of results after action is taken. The action research model describes change as a cyclical process involving joint activities between employees and organisational ractitioners. Figure 2 below compares Lewin (1951) change model to other models of planned change such as the positive model and the action research model all of which describes the phases by which planned change occurs in organisations. Initiation of successful organisational change modified restructuring strategies and organisational efficiencies can be envisaged through these theories. In this model many steps overlap and interact in practise. This simple model has been used to analyse and manage change and can be useful at times. However, it tends to treat people as the objects of manipulation and does not involve them in the change process at all.All three approaches emphasises the application of behavioural science knowledge, involve organisation members in the change process to varying degrees and recognise that the interaction between an organisation and a consultant constitutes an i ntervention that affects the organisation. Lewin’s(1951) change model approach differs from the other two models in that it deals with the general process of planned change whereas the others target specific organisational development(OD) activities. To manage strategic change effectively, it is important to understand its causes. Two main classifications of the causes of change are outlined by the following theorists: 1) Tichy’s(1983) four main causes of strategic change 2) Kanter, Stein and Jick’s(1992) three dynamics for strategic change. According to Tichy (1983) four main triggers for change:TICHY(1983) TRIGGERS FOR CHANGE †¢Environment- shift in the economy, competitive pressures and legislative changes can lead to demands for strategic change. †¢Business relationships-alliances, acquisitions, value chain linkages or core competencies. †¢Technology †¢People-new entrants may have different educational or cultural backgrounds or expectati ons that require change. Source:Mullins, Laurie,J. (1997) Management and Organisational Behaviour 9th. Edition FT/Prentice Hall. (TABLE 3) Tichy(1983) suggests that change is not only inevitable in such circumstances but can be managed to produce effective results. Kanter, Stein and Jick(1992)identified three causes of strategic change: Environment-changes here compared with the situation in the organisation can lead to demands for strategic change.Life cycle differences-changes in one division or part of the organisation as it moves into a phase of its life cycle that is different from another division may necessitate change. Typically, change issues related to the size, shape and influence of such parts and involve coordination and resource allocation issues between them. Political power changes inside the organisation-individuals, groups and other stakeholders may struggle for power to make decisions or enjoy the benefits associated with the organisation. For example, shifts in s trategy from production oriented to customer oriented would be accompanied by a shift in the power balance between those two functions.The researcher suggested that the causes were constantly shifting, sometimes slowly and at other times faster. Kanter, Stein and Jick’s(1992) theory can be directly related to the Health care clinic as the organisation go through the process of change as it relates to the external environment changes so too must the organisation, as one part of the organisation change so too must other parts of the organisation change to ‘catch up’. Internal and external factors influence changes. Kanter, Stein and Jick (1992) identified three major forms taken by the change process. They linked these three categories of people involved in the change process, to produce a three stage process for managing change.These three forms were: 1)The changing identity of the organisation. 2)Coordination and transition issues as an organisation moves through its life cycle. 3)Controlling the political aspects of the organisation. The three major categories of people involved in the change process: I. Change strategists-those responsible for leading strategic change in the organisation. They may not only be responsible for implementation. II. Change implementers –those who have direct responsibility for change management. III. Change recipients- those who receive the change programme with varying degrees of anxiety depending on the nature of the change and how it is presented.Kanter, Stein and Jick(1992) offer one way of structuring and managing aspects of the change process. However, these categories of people only give limited indicators of how to manage the process. Kanter, Stein and Jick’s(1992) model may be suited to major changes than the more common ongoing process. According to Cummings and Worley (2005) there are five major activities involved in order to lead and manage change and they are done in the order in wh ich they are performed. These in order of priority are: ? Motivating change. ?Creating a vision. ?Developing political support. ?Managing the transition. ?Sustaining momentum. A major point to note is that in this model, overcoming resistance to change is required early in the change.The change process in the organisation can be severely affected by resistance to change. People tend to very reluctant to move from their perceived ‘comfort zone’ to some unforeseen place as it relates to change thereby begging the questions of whether their contributions will mean anything for them in the future. Albrecht (1983) provided an interesting model of change in which organisations undergo the change cycle. Individuals also experience symptoms of change response cycle. This cycle is prevalent when change is dictated or imposed by management and internal and external forces. ( Table 4 below refers. ) (TABLE4) Source:Cummings, Thomas G. nd Christohper G.

Edition-,Thomson Southwestern.Kotter(1995) suggests † that for change to be successful 75% of the company’s management needs to buy into the change and really work hard at step and spend significant time and energy building urgency before moving into the other steps. Don’t panic and jump in too fast because you don’t want to risk further short term losses, if you act without being properly prepared, you could be in for a bumpy ride’’ As a result of change many times there is the issue of conflict arising. Conflict is inevitable just as change and assuming that organisational goals are broadly dersiable , there are two aspects of conflict that are relevant and leaders mus t take cogniscance of. According to Hunt (1986) conflict can be highly desirable, it can energise relationships and clarify issues. Conflict can be constructive as well as destructive. the constructive effects of conflict are hat it can introduce different solutions to problems, power relationships can be defined more clearly,it can encouragecreativity and testing of ideas,it focuses attention on individual contributions, it brings emotions out in the open and it provides opportunities for the release of hostile feelings that may have been, or may be, repressed otherwise. Conflict can have negative effects as it may distract attention from the task, it can polorise views and dislocate the group, odjectives may be subverted in favour of secondary goals,it encourages defensive or spoiling behaviour,it may result in the disintegration of the group and it can foster emotional, win-lose within the group. Job design involves the planning of the job. This includes its contents, the methods of performing the job and how it relates to other jobs in the organization (Rahim 2001).Job design and redesign main focus is to put together the needs of the employees that are involved in the different jobs with the production necessitate of the organization in mind. One of the main aims of job redesign is to supply the organizations workers with significant work that fit effectively into the flow of the organization. Enriching, enlarging or simplifying are also goals of job redesign. For the improvement of performance job redesign theory focuses on, job rotation and job enlargement. As in the case it was shown that the general feeling of the employees of the clinic was that there was an absence of job challenge and that technology had simplified the work to be done.According to Herzberg’s theory of motivation, workers motivation to work depends on the nature of the work and how challenging it is. Lack of this challenge will allow employees to become disenchanted with thei r job thus having a negative impact on organizational transformation. Having job challenges will help in motivating the employee to work. Adair (2004) believes that motivation comes from within a person but is fuelled by external factors eg. having work challenges to be able to align themselves to achieve a specific goal, (the goal being a challenge but yet it is attainable by the employee). Job rotation where the employees will be allowed to work on different tasks or in different departments.This will increase job satisfaction and would have helped the employees as they would have had the opportunity to perform different tasks, thus inhibiting boredom on the job. Learning will also take place as employees also learn new tasks and have different responsibilities with job rotation. Job enlargement whether horizontal or vertical would also lead to a more successful organizational transformation as it would also help in giving the employees a challenge as they will have more to do. Ti me is also extended so that the challenge of doing more is realistic. Self esteem will be contributed to as the employee would be entrusted with exercising judgement thus having added responsibility for tasks.Job design and redesign is mainly done by the management of the organization who are responsible for making decisions about how to design those jobs ( Mintzberg 1973) as they see fit. Although managers would have more influence and control over job design than they do over structure, technology, culture, relationships and people ( Hackman & Oldham 1980), the time and attention of managers would still be greatly needed (Dutton &: Ashford, 1993). Pfeffer(1994) believed that the depending on how managers make decisions about job design, it can be a liability or a potential source of competitive advantage for organizations however, many managers often use simplified work as the default approach to designing jobs (Campion &: Stevens, 1991). 3. 0. ANALYSIS/FINDINGS:The researcher in her analysis of the case study of the particular health care clinic sought to ascertain where the problems were and attempts to ascribe the requisite solutions. There were certain strengths as well as considerable weaknesses associated with the case study. It was found that Lewin’s(1951) models were followed to the letter in the structure of this health care clinic and that factors outside these frameworks were not used thereby creating obvious gaps. TECHNOLOGY: Tichy’s(1983) four main triggers of successful strategic change identifies technology as an important driver in the change. As is the situation in the case study it was found that with the advent of new modern technology strengths as well as weaknesses are abound.The medical technologists in the bio chemistry department were either inept with the new technology or were not prepared for the imposition of the new technology thereby dissatisfaction was wide spread, which can be seen as another weakness. Technologi cal shifts can substantially impact on the quality or content of the work and may ultimately influence the factors that affect survivability of the organisation. SOURCES OF DISSATISFACTION Paragraph 2 of the case study identifies several sources of dissatisfaction among the technologists that were of concern. The under mention identifies the concerns together with the possible cause and effect and likely solutions. Under utilisation in their work†-this can be seen as a weakness in the organisation and could have been possible as the OD staff failed and or neglected to take into consideration issues such as job design and redesign RAHIM (2001), job rotation, job enrichment, job enlargement and job evaluation on employees at the health care clinic. â€Å"Communication within the laboratories was insufficient†-it is apparent that the communication channels between laboratories were severed or perhaps were insufficient. As such the OD experts should have embarked on team bu ilding workshops and organisational development seminars and sufficient enough training and development exercises. Work wasn’t evenly distributed†- this would suggest that there was a certain lack of supervision in the laboratories and there was a failure to have equity distribution in assignment and management of tasks. The issues of capacity management and production planning are areas that OD experts should have looked at. â€Å"Medical staff didn’t treat them with the respect that they deserve†-this clearly suggests that the medical staff felt that the technologists were their subordinates and felt that way because the technologists may be less remunerated as compared to the medical staff. As such OD staff should take into consideration issues such as reward management systems, merit recognition eg. Employee of the month, performance pays system, team based pay and a comprehensive performance related merit system of remuneration. The advent of technolo gy had had simplified the work to the point that it no longer seemed to require the level of training common among medical technologists†-this would suggest that technologists should have had enhanced training in other skill sets or multi skill training which would give them the extended capacity to build manpower capacity. â€Å"Studies in personnel management literature†-there is no such evidence in the case study to suggest that there were any studies in the personnel management literature carried out. â€Å"Job challenge was a primary cause of job turnover†-this is an issue really of job retention as opposed to job attrition. By looking at performance appraisal strengths and weakness can be determined.In looking at job turnover OD require job retention, job security and career and talent management. LEADERSHIP: The art of leadership is saying no, not yes. It is very easy to say yes. (TONY BLAIR, 1994) Are leaders born or made? Trait (1950) theory seems to sug gest that leaders are born and not made, yet Stodgill(1949) and Mann (1959) suggests that there are few relationship between the traits possessed by leaders and their performance. The Trait (1950) theory that leaders are born failed under scrutiny (Zaccaro, 2007). Kirkpatrick and Locke (1991) having examined existing literature on leadership suggests that there are six leadership traits.They are: 1-Drive 2-Leadership motivation 3-Honesty and integrity 4-Self confidence 5-Cognitive ability 6-Knowledge of the business As in the case study there is no clear indication as to the leader (Weisbord 1978) of the change process as it is reputed that the OD staff had discussions with the managers. Clearly no one took charge of the change process from the onset of the planned change. There is no evidence to suggest whether the OD staffs were adequately qualified to conduct such a change process or whether the interviews were conducted professionally. COMMUNICATION Communication is a key compon ent in the facilitation of any change process.For this reason communication is heightened importance when change is needed. Bordia et al (2004) suggests that communication during change is vital to manage employee uncertainty and feelings of loss of control. As was the case in this case study there is hardly any evidence to suggest that there was a proper reporting structure so that information on the change initiatives were being communicated to the technologists by the OD experts. To this end came the issue of the readiness for change as this is an important indicator to coping with resistance to change so suggests Armenakis, Harris and Mossholde(1993). Communication strategies need to emphasize two messages.They are: 1- The need for the change, that is, indicating what the organisation is doing as opposed to what it should be doing and 2- The ability to change successfully, that is, it is important that the employees believe that the change could be done thereby encouraging them to make the extra effort. TIMEFRAME: Apart from using volunteers to assist in the analysing of the data which is in itself questionable as there is evidence that they are overworked and not properly remunerated. The OD staff administered questionnaires which asked for confidential opinion as opposed to change or job analysis questions and there is no indication of its contents. These questionnaires sought only quantitative data.Whether the truth will be written on those questionnaires is anybody’s guess as there is no validation of the data. There is no clear definition as to the timeline for the project and no implementation plan. The random sampling data collecting took two months seems to be incredibly long for such an exercise. To suggest that two years later the OD staff evaluated the results of the change program was incredulous to say the least as this was certainly not an effort in organisational transformation but rather an incremental change plan. This was an exerci se that was limited in scope, time and cost thereby failing to meet its objectives. RESISTENCE TO CHANGEResistance to change is a widely used term that generally gives a bad or a negative connotation. It us usually asked of employees to change something in the organisation that they may have been comfortable with for their entire life. That change will not come easy at all, there will be some anguish and fight and may even be the source of collective group action like strikes and industrial action by employees. This is not necessarily a bad thing. Ford and Ford(2009) suggests that resistors to change should not be overlooked but that resistance should be taken in a positive light and accepted as a form of feedback that can actually build and encourage the change process.Pockets of resistance can also be found with the Lewin (1951) model of unfreezing, moving and refreezing. As the activity of unfreezing comes to an end resistance is usually found as employees attempt to move. This i s quite natural as without proper communicating many are unsure of their future especially the employees who have fallen into their comfort zone. As with the case study there was a definite feature of resistance to change. 4. 0. REFLECTION: This change process was a failure from its inception because the very basic of protocols were not adopted. The OD staff sought to enlist volunteers who do not have the requisite educational capacity to carry out that vital function of collecting and analysing data.The human resources department should have been the ones directly involved in the change process. The change agent should have been engaged who is a highly trained professional in organisational development to lead the drive towards organisational transformation. In this case study the data collected would at best be unscientific and unrealistic to say the least. Change, whether planned or emergent can take a number of forms, each of which requires a different type of action. Utilising collective methods of action research together with capacity building and the will to include people in the change process will go a long way in achieving successful change.In conclusion it must be said that there are unprecedented opportunities and challenges in the health care industry for which organisational development (OD) practitioners must be aware of and as such there can be significant positive growth and development by linking strategic activities of the organisation towards the direction of organisational transformation. Organisational transformation can also be achieved by being able to facilitate integration of people and processes across traditional department and organisational boundaries and by acknowledging competencies and integrity.
