A History of Violence, Released in 2005

â€Å"A History of Violence,† released in 2005, is an American crime thriller which demonstrates and relates to numerous topics discussed in Psychology: An Exploration. Different psychological disorders and theories can be seen throughout the film. Tom Stall, the main character, kills two robbers in self defense and becomes a hero. However, his over night popularity thrusts him into the spotlight and causes members of an organized crime family to begin harassing Tom and his family. The mobsters claim Tom is not who he portrays himself to be. In the beginning of the film, two sought after criminals nonchalantly murder motel workers and a young girl. They exhibit no regret or emotions after the killings and continue on their crime spree. Next they are shown casually plotting a robbery to obtain cash and a free meal. The two men walk into the restaurant, demand service, and attempt to assault and murder the workers and patrons within. However, their scheme is abruptly ended when Tom Stall, the restaurant owner, kills both robbers. Both of these criminals displayed antisocial characteristics. In chapter 12, Psychological Disorders, an antisocial person or sociopath is defined as â€Å"lacking in conscience or morals; users and con artists who experience no regret or strong emotions. † This definition defines the robbers psyche faultlessly. Intermediately in the film, Tom Stall’s son, Jack stall is shown being bullied. Bobby has continually harassed and bullied Jack for no apparent reason. Usually Jack tells jokes and ignores Bobby’s constant harassment. However, in this particular scene, Jack has had enough and retaliates. Bobby is an adolescent and may be dealing with a psychosocial crisis discussed in chapter 7, Development Across the Life Span. Erikson’s identity versus role confusion is defined as the â€Å"fifth stage of personality development in which the adolescent must find a consistent sense of self. † Bobby may have come into this stage without successfully completing the earlier four stages. The aftereffect of such an occurrence may be a juvenile delinquent like Bobby. His acts of bullying may be his way of â€Å"fitting in† or being â€Å"cool. † Tom also has a daughter, Sarah Stall. In one particular scene Sarah is awakened in the middle of the night by a bad dream. She wakes up screaming and expressing her concern of monsters being in her room. Tom rushes to his daughter’s aid and the rest of the family soon follows suit. Tom and others comfort the little girl and emphasize that she is safe and has nothing to be afraid of and should go back to sleep. Sarah eventually calms down and is able to go back to sleep. Chapter 7 discusses numerous parenting styles. One of those styles is authoritative parenting which is defined as a â€Å"style of parenting in which parents combine warmth and affection with firm limits on a child’s behavior. † Although Tom’s first instinct was to comfort Sarah and ease her mind he also made it clear that it was bedtime and time for her to quiet down and rest. Tom displayed a perfect example of authoritative parenting. After repeatedly denying accusations and claims of being an ex-gangster named Joey, Tom finally admits to his wife Edie that he was indeed involved in organized crime. Edie is disgusted by Tom’s confession and becomes ill. She lashes out and says, â€Å"What are you? Like some multiple personality schizoid! † Tom is stunned by her anger but replies by saying â€Å"I went out to the dessert and I killed him (Joey). I spent three years becoming Tom Stall! Schizophrenia is defined chapter 12 as a â€Å"severe disorder in which the person suffers from disordered thinking, bizarre behavior, hallucinations, and inability to distinguish fantasy and reality. † Although Tom’s life as a small town restaurant owner was completely false, he knew this and could distinguish the difference between fantasy and reality. Tom may have somewhat displayed symptoms of Schizophrenia but a different delusional disorder may be a better diagnosis.

Cesar Chavez A Great Leader Essay

Cesar Chavez, union leader and farm worker advocate, was born near Yuma Arizona on March 31, 1927. On March 23, 1993 this great man died in San Luis, Arizona. It is said that his hunger strike contributed to his death. Cesar’s commitment to farm workers was shaped by his own experience in the farm industry and his parent that taught him how imperative it was to help others. As a child, Cesar worked restlessly in his family’s farm. Later the family had to move to California because their farm was taken away for lack of money. They worked very hard in farms for very long hours and helped their coworkers there. A few years later Chavez volunteered to serve the US Navy. Cesar later came home to marry his girlfriend and transformed his life as a community leader and labor organizer. Chavez founded the United Farm Workers Association in 1950 after community service. Chavez engaged in nonviolent acts to bring attention to the farm workers. Others before him tried and tried to commit to the union but later gave up and turned to violent acts. He faced many challenges through the years. This however did not stop him. He was willing to give his own life so that the union could continue and that violence was not used. Cesar made the struggles of the farmers known to the country. The terrible sufferings of the farm workers and their children, the crushing of farm workers dignity, the dangers of pesticides, and the denial of election for the workers is what kept Chavez going. One of his first successes was getting grape workers to sign union contracts. Cesar went on marches, boycotts, pickets, and strikes. He sought to train others and send them to other cities so they could also use these same tactics. His peaceful strategies brought attention to numerous friends and supporters like Robert Kennedy and Jesse Jackson. This great man proved that with self-sacrifice and without violence one could get justice for the people. He was an efficient leader with determination and clear goals. He always let people know that it was for them â€Å"Si Se Puede† was his saying â€Å"It Can Be Done†. This humble man fought for what he believed for and till today his organization is abundantly thriving with freedom.

A Brief and Simple Analysis of Chapter Two of Grendel

(Beginning in paragraph two of Chapter 2, and continuing throughout the chapter, Grendel describes how he used to be as a child. How does this description compare or contrast with the behavior of the humans when they are fully-grown? ) In chapter two of Grendel, John Gardner takes the readers into a deeper aspect of Grendel’s life. Most specifically, this chapter revolves around the childhood life of Grendel. Readers are able to access the mind of Grendel as a child, through a chapter that is almost entirely structured as a flashback to the situation that, arguably, may have transformed the typical ‘kid’ into the man-eating beast one was introduced to in Beowulf. However, Grendel isn’t to blame for his future actions, for his entire existence was tarnished when his young, impressionable mind was altered. Grendel’s innocence as a child was robbed, as with all children, when a new understanding of the world’s harshness was grasped. It almost seems, however, that Grendel’s behavior as a child is mirrored in the â€Å"fully-grown and adult† humans he despises so much. Throughout the chapter, Grendel seems to place himself on a risen, intellectual pedestal, with the humans he deems childish roaming blindly and stupidly hopeful far below. As observed through history, the Anglo Saxons were a war like people, with religious seafaring clans that pledged themselves to an invisible greater-power and who traveled far and wide in their seafaring explorations. These traits are identical to Grendel’s memories about his childhood, â€Å"I used to play games when I was young†¦. explored our far-flung underground world†¦.. an endless wargame of leaps†¦whispered plotting with invisible friends†¦childish games†¦Ã¢â‚¬ . When Grendel looks out to the humans, he can’t help but recognize his own childhood ways in their lifestyle. The humans’ endless praying and constant adventure is laughable in Grendel’s eyes because it reminds him of his own past existence before his hope and innocence were tarnished by the daunting reality of an unpromising life. Grendel’s attacks may not have been to hurt the humans for the heck of it, but rather, Grendel may have seen it as helping the humans into escaping an oblivious life, just as the humans did to Grendel when he was a child. It may be here that Grendel’s anger arises; Grendel absolutely knows his childhood was robbed from him, and it becomes his duty to enlighten the stupidly arrogant humans to recognize their true existence as well. The humans, as we all know well to much, seem to be stuck in an endlessly spinning cycle of pointlessness and Grendel is the third person outsider who wants to bring upon the harsh reality of life. On page seventeen, Grendel states â€Å"the shocking separateness from me in my mother’s eyes†¦. [I would] hurl myself at my mother†¦comforted, I would gradually ease back out into my games. †. Grendel’s feelings of uneasiness and misunderstandings are eased almost immediately with a hug from his mother, consoled with the love and connection of another. As an adult, Grendel almost despises such comfort, growing obviously angry with the immediate comfort of the humans with the passing of a clan member with the simple thoughts of unification and the extension of life. Grendel lost that sense of spirituality and companionship, and seems to deem it childish and almost unnecessary as an adult. We see Grendel as an independent being in Beowulf, and his murders are controlled in an area where companionship and joy are absolute and strong; the mead hall. It is more than a coincidence that Grendel chose to destroy the heart of the Anglo Saxon community, for he wished to destroy the hearts of the people. His continuation of destruction for what were the next twelve years were not because he enjoyed the killing and eating of the men (because it was stated that he didn’t) but because he realized that the hopefulness and unification of the community would not back down. Grendel’s own childish ways are exhibited here, for he continues his persistence until he can no longer. In Grendel’s eyes, Grendel is a monster who, almost as the Anglo Saxons believed, has grown wiser and more knowledgeable with the endless spinning of life he so ardently chooses to misinterpret. In chapter two, Grendel fixes himself far from the humans that he seems to understand so fully. In fact, Grendel himself is a child who lost his innocence and optimism so abruptly that he didn’t recognize it. Grendel is angry and jealous of the humans because he sees in them the traits that he possessed when his life posed meaning. Grendel became a nihilist, to some extent, because he decided to reject the life and being he was becoming. He instead chose to isolate himself so dangerously from his feelings that he had no other option but to inevitably give in to what he thought he should become. Upon the arrival of his death, Grendel was experiencing was seemed to be a type of mid-life crisis that developed from his childhood, or rather because of its absence.

Acquisition and Disposal of Land and Real Estate Essay

Acquisition and Disposal of Land and Real Estate - Essay Example The acquisition of land and real estate requires an official process that is based on risk analysis, and financial analysis.Real estate refers to things which are not movable for example land and improvements permanently attached to it. There is a difference between real estate and real property. The ownership rights that are associated with the real estate are called real property. During acquisition of real estate, the investor acquires the land, all the physical assets of the land and all the things which are permanently attached to it. The investor also gets property rights which include the right to control, occupy, develop, exploit, lease, improve, and sell the real estate.It is important to differentiate between real estate and real property because different parties have different rights on a given part of real estate. Property rights can also be described as the right of a person to use, dispose, possess and enjoy his property. (Fisher & Brueggeman 2004)The value of real est ate is the total price that an individual is willing to pay so as to acquire the benefits associated with all the property rights. It is important to note that it is not necessary for a person to be the owner of the property so as to have rights to it. A person who rents a piece of land is not the owner but he has the exclusive right to use the land as he wishes for a certain period of time. In exchange for the right to use the land, the tenant/lessee is willing to pay a certain amount of money. (Fisher & Brueggeman 2004) There are certain interests that an investor can acquire from a piece of property. An interest in real estate can be defined as a right or claim on property, production or its revenues. The interest in property is created by the possessor who can pledge the property in order to attain a certain objective with out giving up the property. An example of this is where a person pledges his land as security when he wants a loan from a bank. An easement is an interest in land whereby a person has the right to use the land leased for some special purpose. (Fisher & Brueggeman 2004) The legal aspect of a real estate acquisition is very important. It can assist in knowing the benefits of other persons who have some rights over the property. Often conflict arises concerning the rights to be given to the people who are holders of interests in the property. (Fisher & Brueggeman 2004) Classification of Estates There are certain categories of estates that can be differentiated in terms of the nature of rights that come with the ownership of an estate. An estate in possession allows the owner of the land immediate enjoyment of the land. An estate not in possession is a future estate in land and it doesn't give the buyer any rights to the estate until some time in the future. It will not change to an estate in possession until some future occurrence takes place. (Fisher & Brueggeman 2004) Estates in possession are of two varieties: leasehold and freehold estates. They are differentiated on the basis of the certainty of their duration. A freehold estate lasts for an indefinite period of time which means there is no date that the possession to the estate ends. Leasehold estate ends after a certain amount of time. It is a right to possess and use the property owned by another for a period of time. Examples of leasehold estates include the renting a residential estate whose contract is to be signed every year. A freehold estate can be the purchase of a home in the suburbs which can be leaved in generation after generation. (Fisher & Bruegg

Trusted computing and TPM-enhanced software Essay

Trusted computing and TPM-enhanced software - Essay Example Trusted Platform Module is not entirely competent in safeguarding computer systems from the associated threats in the modern world. Trusted Platform Module enhanced software entails securing the software part of a computer device, such as the generation of cryptographic keys. It ensures that the systems software is safe and convenient for use. Another software aspect is the random number generator, which eases the use of computer programs. The software of any computerized device is readily usable, easing the operation of the systems. TPM-enhanced software enables binding, which is the encryption of data using a bind key. It is from the storage key that the bind key arises. The TPM-enhanced software also allows sealing, which is the encryption of data, similar to binding. Operating on such a scale creates room for significant limitations and backlashes. The associated limitations result in major failures in the software of the computer system, which to my opinion is the cause of system failure. Numerous accusations exist, resulting in lack of trust in the system. Some of the associated failures include the accusation by Cambridge’s Ross Anderson that Trusted Computing is anticompetitive in its quest of locking users in the enforcement of DRM (Kim, 2009, p. 6). In my opinion, the invasion of privacy is among the failures of the system, for this reason limiting the success of Trusted Platform Module enhanced software as a system security platform for computer software. I believe that the scheme has not been able to safeguard computer software safely, without having to affect the user’s usage of the machine. Privacy invasion affects the user’s trust in the system since he or she has to remain watchful as they use their computerized systems. The TPM- enhanced software entails integrity measurement, reporting, and storage. The company, therefore, has access to the user’s whereabouts

Stress Effect and Management - Essay Example ing for a picnic with my kids, I would first get panic attacks on how to go there and after reaching the spot, I would worry about how we would get back. By practicing Yoga, I have become calmer and I am able to control these panic attacks, plan my activities better and small issues don’t upset me too much. Yoga has helped me to reduce the harmful effects of stress. Some of the harmful effects that stress causes are headaches, exhaustion, reduced resistance to common colds and flu, digestive problems and acidity, distraction at work that can cause attention lapse and cause injuries, increased occurrence of Type 2 diabetes, premature aging, insomnia, unable to concentrate and focus on work, loss of sense of humour and tendency for rash flare-ups that can cause strained relations with colleagues and other bad effects. Too much of stress is known to cause migraines, cluster headaches and tension headaches and these cannot be cured by taking medicines. Stress also causes exhaustion and a general feeling of tiredness that drains away the creative abilities and victims feel tired and drained out after work. Too much stress causes natural resistance of the body to reduce and people become ill more frequently with colds, flu and cough and they also have problems such as ulcers caused by too mu ch secretion of the bile juice inside the stomach.

Other than these, stress also makes people irritable and they are prone to flare up at colleagues, with very little provocation. Such behaviour causes a breakdown in interpersonal relations and effects work performance besides vitiating the atmosphere at homes. The whole observation is that stress is a needless by product of life that reduces the quality of life and causes

Writing about Hospitality Industry - Research Paper Example With expectations built on prior basic research aided by an omnipresent internet spewing details with adventurous reviews, a revised marketing strategy focusing on the Price-Conscious, Hyper-Connected customer is but a priority. A multi-billion-dollar technology, E-Hospitality has provided an avenue of cultivating the ultimate customer experience, right from improved availability to accommodate travelers’ needs round the clock to the enlightening, participative forums where professionals share information in private chat rooms, with the possibilities of developing new friendships and/or business connections (Hatch par 3-4). The technology has enabled sharing of efficiency boosting experiences in terms of managerial capabilities, ethical dilemmas in the same, and ad targeting that reaches out directly to the travelers who are most likely to book reservations. The utilization of the innovative ideas is barely past the takeoff stage, with hotels sparingly replacing the traditional methodologies in their managerial aspects. The injection of advanced skills in technology into this particular industry is, however, fundamental in reducing costs [the main objective of business organizations] and conserving the world’s limited resources for a sustainable future (Nikolis par 2). Leisure professionals, therefore, have no choice but to adapt to the new reality to maintain

Is Excessive Food Waste an Environmental Concern Essay

Is Excessive Food Waste an Environmental Concern - Essay Example This research will begin with the statement that according to a report by the U.S Environmental Protection Agency (APA), remarkably few citizens know that excessive food waste is an environmental hazard. Excessive food refers to wasteful practices by consumers and during production. Most people argue that since food is biodegradable, it does not pose a threat to the environment. However, a report published by EPA revealed that when food rots, it produces a greenhouse gas known as methane. Amazingly, methane is twenty times more damaging to the environment than carbon dioxide. On the other hand, the U.S Department of Agriculture (USDA) argues that if only five percent of Americans’ food scraps were recovered, it would be enough to feed four million people for a day. USDA reported that close to 26 million tons of wasted food get thrown away in garbage annually. In fact, in 2010, food approximated to 34 million tons went to waste. In addition, food waste formed the single largest component of municipal solid waste reaching incinerators and landfills. EPA notes that the U.S government spends close to one billion dollars just to dispose of all its wasted food. This is exceedingly astonishing. The excess money spent on the management of wasted food can be used to run vital government departments. Experts from the University of Arizona believe that the country’s environmental impact can be reduced by 25 percent if Americans can reduce their food wastage by a half. This appears to be true because the Food and Agricultural Organization (FAO) indicated on 10th January 2012 that one-third of the food produced for human consumption globally, goes to waste every year. FAO reported that consumers and retailers in the U.S waste close to 40 percent of edible food annually. The data from FAO is also astonishing and calls for immediate actions. From the data reported earlier, it is clear that excessive food waste is becoming a serious environmental hazard. Consider ing the report produced by FAO, the U.S is just a representative of many nations whose citizens waste tons of food annually. The most alarming bit is that methane, the gas produced from food rot, traps heat in the atmosphere 23 times more than the widely known carbon dioxide. Since global warming affects the whole earth, stakeholders should consider passing international regulations that regulate the quantity of wasted food a country produces, in order to curb methane overproduction.

This component will be met through establishing good relationship with the credentialing members and the rest of the staff for support as well as proving my effectiveness and efficiency in the institution. The most eminent of the challenges is the privacy issue. Privacy is crucial in any institution of the patient’s records. With technology, the privacy challenge has increased tremendously due to sharing of hospital server and hence leaving the information available to hackers. The most effective of the solutions is to separate to keep on changing the passwords as the most basic of the solution as well as establish different access codes that need specific identification information that is only given to the hospital staff. The codes should also be constantly changed to prevent the information from easy access. The backup information should be accessed by very few individuals and only available with high security

Change Junctures in the Change Management Process

Change Junctures in the Change Management Process Critical change junctures in the change management process at Spectrum sun-Glass Company Introduction In the simulation undertaken, I am the Director of Product Innovation under the unit handling Research and Development for a company called Spectrum sun-glass Harvard (2012). I am very passionate about sustainability and would be very like the company to offer green products to its clients. At a recent company retreat, I tried sharing the discussion I had had with the Vice President of our biggest retail customer, Bigmart; in which he had intimated that Bigmart was about to require all their suppliers to, go through the Green Certification process. As I proceeded, most of my colleagues were displeased; with the Chief Finance Officer, Paul DArcy and the Vice President for Operations Luke Filer, coming out very strongly, against my proposal. I however received support from the Vice President (VP) of Sales and Marketing, Leslie Harris and Vice President (VP) for Human Resources, Mary Gopinath. As a compromise, the CEO appointed me as the head of a team from the different departments to develop a plan that is acceptable to all. As I lacked any formal authority, I had to rely on my personal credibility which was quite high at this point. 2.0 Section 1: 1st decision: Hosting a town-hall meeting in week 25 and the reasoning behind. To start with, I undertook a range of decisions to raise my personal credibility and increase awareness. For instance, in week 0-24, I had private interviews with colleagues (particularly those opposed to the initiative), I received support from a consultant, and I received the CEOs support, to mention but a few. However, the decision that most advanced my change management process, was the town hall meeting that I held in week 25. This town hall meeting alone moved the following individuals from the awareness to the trial stage: Andrew Chen, Walt James, Bob Ingram, Yao Li, Mark Robert, Anne Thompson, Louise Crysh and Dianne Mcnatt. The reasoning behind this decision was informed by Robert Ciadini as quoted in Cliffe, S (2013) who says that ; if one intends to persuade people, one needs to appeal to six human responses namely; people will follow through with commitments that they have made publicly, people will do things that they see people similar to them do, when people are uncert ain about certain things, they tend to look towards experts and other possible sources of information, people are more likely to accept proposals from someone that they like, people tend to respond positively to people who have helped them in the past and people value things whose supply is limited. The town hall meeting was therefore a perfect lever for me to use, as it enabled people to accept my proposal, if other people in the group were to accept. Secondly, it enabled colleagues to make a public commitment to my proposed change, than say, in the private interviews. In addition, the town hall meeting was a perfect opportunity for me to share my extensive knowledge on the issue of sustainability and why it is important for our company and future growth. In the face of uncertainty, my colleagues were then more likely to defer to me and agree to my proposal. Looking back, at the levers that I used, I should also have continued with personal interviews, particularly with the key opp onents of my plan. This strategy of co-opting antagonists is well elaborated in Pfeffer, J (2010), as a way of winning over opponents and giving them a stake in the process of change. Personally, this could also have involved making concessions to the CFO and the VP-Operations in private, so that they start to own a part of the plan. 3.0 Section 2: How I would implement the change action above in practice In practice, I would seek to utilize the levers provided in a concurrent fashion. Whereas, in the simulation, I could only hold a town hall meeting, for instance; I would in practice, seek to complement this with a public statement of support from the CEO. I would also look at having the consultants report delivered during the townhall meeting. In addition to these formal avenues for influencing my colleagues, I would seek out opportunities to help out colleagues. In this way, I would create an obligation on their part to reciprocate. This would therefore ensure that when they are called upon to support my proposal, they would feel conflicted, not to support it. Similarly, I would try to make every effort to get myself liked by colleagues, in very casual settings. This liking would them make it more likely, that they would support my proposal. I would focus less on the means, and focus more on the end. That is, I would be extremely flexible with the levers and concentrate more on the goal of having management agree to Spectrum-sun glass making green products. I would also seek to appreciate the arguments of my colleagues, in Finance and operations. To allay their fears about the financial and operational challenges of the new proposal, I would invite their contributions on how these can be addressed. I would be willing to accept these suggestions as it helps me attain my overall goal-albeit with certain changes. In addition to the personal interviews and town halls, I would also look-out and encourage opportunities for my colleagues to air their views and even reservations about my proposal. This would help me to understand the main issues that my opponents value and would then enable me to respond appropriately. 4.0 Section 3: 2nd decision/Juncture: Building a coalition of support in week 43 and the reasoning behind In week 43, I sought to build a coalition of supporters among the staff, as a way of trying to move the organization from the awareness to the movement stage of the change process. Not only did this decision, have no effect on the organization; it also resulted in a loss of my credibility as some staff were not enthusiastic about the idea. In making this decision, my assumption had been that there was then sufficient interest, in my proposal, among the team. In fact, this result (the failure to build a coalition of support) could be explained by the various theories about organizational culture. For example, Chatman, J, Eunyoung Cha, S (2003) posit that organizational culture is very powerful as it energizes and rallies employees around common perceived goals or objectives. The lack of interest by the employees of Spectrum sun-glass in joining a coalition of support could therefore be partially explained by the culture of the organization. This view is supported by, Goffee, R, Jone s, G (1996) who explains that organizations can be grouped on the basis of their cultures, as follows: Networked Organizations-in which there is a lot of informality, cliques and limited commitment to company goals, Mercenary Organizations,-in which decisions are made by top management and enforced swiftly throughout the organization, Fragmented organizations-in which there is limited solidarity and collaboration across departments and communal organizations, in which there is a lot of socializing at work and solidarity. Based on the above metric, I would classify Spectrum sun-glass as a Fragmented company where there is limited solidarity and collaboration across departments. Alternatively; and as explained by Prof Tim Morris in his lecture on leading through culture; company cultures can be assessed on five dimensions, namely; whether it has a single or multiple cultures, whether decision making is low or high consensus, whether there is an internal or client focus, whether the pe rformance orientation is high or low and whether there is internal cooperation or competition. Based on the above criteria; I would rate Spectrum sun-glass as having a single culture, high consensus decision making, client focus, a high performance orientation and internal competition. With the above information and in retrospect; I should not have sought to create a coalition in such an organizational culture, at the time I did. Instead, I should have concentrated on enabling change through consolidating and relying on my personal credibility, communicating my proposal and making the necessary emotional connection and training. 5.0 How I would implement the change action above in practice In practice, I would start by analyzing the existing organizational culture. I would then craft a very convincing slogan to motivate my colleagues to adopt my approach. For instance, Go Green, More Profits, and More Pay. To further promote interest in my proposal, I would create a sense of urgency, by making the slogan action oriented, Goffee, et al, (1996). As this is a fragmented and mercenary organization, I would also try to organize dialogues on my proposal in informal settings; like lunch, parties and so on. As these parties are enjoyable for those who attend, this tends to increase my likability and the social dynamic within the group. It would also be critical for me to create a place of psychological safety to ask questions about my proposal, to receive honest feedback, to discuss any reservations and errors of approach openly. In this way, I would reinforce the solidarity of the group and its ability to socialize Chatman, et al (2003). 6.0 Conclusion In the end, I was able through the use of the various levers to have eighteen adopters by week 56. This translated into a change efficiency ratio of 0.32, which is high. My change leadership skills (the mishaps, notwithstanding) ensured that I was able to convince a critical mass of managers to adopt the initiative on sustainability. This significantly improved the financial prospects of the company and my professional prospects.

Analysis Of The Wheatstone Bridge

Analysis Of The Wheatstone Bridge This Term Paper is about topic Wheatstone Bridge. A Wheatstone bridge is a device which is used to find the unknown resisitance. It is an instrument or a circuit consisting of four resistors or their equivalent in series which is used to determine the value of an unknown resistance when the other three resistances are known. If talk in some little detail then wheatstone bridge contains the four resistance in which one is unkown resistance which we have to find ,one is variable resistance which is also called the rheostat of the circuit and two known resistance. It also contains the galvanometer for the detection of the current and it is also use to find the direction of current. The various use of wheatstone bridge is as under:- It is is used by electrical power distributors to accurately locate breaks in a power line. It is also used to monitor sensor devices such as strain gauges. Such devices change their internal resistance according to the specific level of strain (or pressure, temperature, etc.), and serve as the unknown resistor RX. Meter bridge, post office box and Carey Foster bridge are instruments based on the principle of Wheatstone bridge The basic use is to measure the unknown resistance. What is a wheatstone bridge? The wheatstone bridge is an instrument which is generally used to measure electrical resistance by balancing a bridge circuit. The bridge circuit contains four resistance, one of which contains the unknown resistance ,one variable resistance and two known resistance. Introductions to Wheatstone Bridge:- Wheatstone Bridge, a device for measuring electrical resistance. In wheat-stone bridge four resistance R1, R2, R3and R4are connected end to end with each other to form a closed loop. A sensitive galvanometer Gis connected between their junctions. One form of Wheatstone bridge is shown in the following example:- For example:- When the Wheatstone bridge is connected in an electrical circuit, part of the current flows to the object whose resistance is unknown and part of current flows to the resistor of known resistance. If more current flows through one side of the circuit than the other, the galvanometer shows the deflection. Due to potential difference create in between them when the current flows equally along both sides of the bridge then the galvanometer shows zero deflection. Thus the bridge is balanced, the unknown resistance is calculated by using formula. The formula is:- R1/R2=R3/R4 Where R1 is the unknown resistance. R2 is the variable resistance R3 and R4 are the known resistances Generally wheat-stone bridge is used to determine unknown resistances. Conditions for wheatstone bridge:- There are two conditions for wheatstone bridge which is as under:- Condition-1:Galvanometer is always in zero potential in the circuit. Condition-2:We should have to take one variable resistance. History of Wheatstone bridge:- [link 1] Wheatstones bridge circuit diagram. A Wheatstone bridgeis an electrical circuit invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. It is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of bridge contains the unknown component and variable component. Its operation is similar to the originalpotentiometer. Potentiometer :- [link 2] A potentiometeris an instrument for measuring the potential (voltage) in a circuit,they were used in measuring voltage. Creation of Wheatstone bridge by different scientists:- [link 5] 1) A scientist and mathematician, Samuel Hunter Christie, developed the circuit to measure unknown electrical resistances and first described it in 1833. The bridge worked because of the special diamond-shaped arrangement of the four resistors. Electrical current from a battery split into two parallel branches of the circuit. One consisted of a resistor with a fixed, known resistance and an adjustable resistor, also with a known resistance. The other leg contained a resistor of fixed and known resistance and another whose resistance needed to be determined. By using a galvanometer to balance the current flowing through the two branches, Christie could, with the help of a little math, determine the value of the unknown resistor. 2) Then another British scientist, Wheatstone, came across Christies description of the instrument, which Wheatstone referred to as a differential resistance measurer. A prominent member of the Royal Society of London, Wheatstone was well-positioned to give the tool a popularity boost. He gave an account of Christies invention at an 1843 lecture, and soon after it came to be called the Wheatstone bridge was used in telegraphy and other applications. Wheatstone himself, however, gave full credit for its invention to Christie. But in translations of his lecture that appeared in Germany and France the following year, Wheatstones attribution was nowhere to be found. In addition to bringing the device to public attention, Wheatstone improved the design (Wheatstone developed the rheostat, a variable resistor) and found several new uses for it. By changing the type of elements contained in its legs, the Wheatstone bridge can determine unknown capacitances, inductances, frequencies and other properties. Besides Wheatstone, several other scientists helped extend the range of the device, including William Thomson, Lord Kelvin and James Clerk Maxwell. This sensitive, accurate method for measuring resistance is still widely used today. Theory of Wheatstone Bridge:- To understand this circuit, consider the following Figure to be two voltage dividers shown below: When the bridge is balanced, the voltages measured by V1and V2are equal, hence no current flows through the Galvanometer G in above figure. Since V1and V2are at the same voltage, the resistance ratios Rx/RSand l1/l2are equal. Because the slide wire has a uniform resistance per unit length, the length ratios l1/l2is equivalent to resistance ratio R1/R2. How Equipment of wheatstone bridge works:- [Link 8] The current flows from positive to negative through the circuit.When it reaches Point Ain the diagram, it splits and travels through either one of two Known Resistors, R1 or R2. Resistance is measured in a unit called an ohm. Here we notice that when this applet initializes, the resistance at R1 is 1 K ohm, while at R2 it is also at 1 K ohm. After the diverging currents pass through their respective resistors (R1 or R2), each reaches another fork in the road. At this point, if the bridge is not balanced, some or all of the current from either the R1 or R2 path will diverge down this middle path that bisects the square created by the circuit. The Galvanometer ispositioned on this middle path which generally tells the presence or absence of current.The direction of this current is determined by the value of the Variable Resistor(R3). Here at this time the bridge is not balanced because the ratio of resistance on the known leg (R1/R2) is not equal to the ratio on the unknown leg (R3/R4). This is where the variable resistor which is also called rheostat of the bridge comes into play. It can be adjusted until no current flows down the middle path. When that is achieved, the Galvanometer reads zero and the bridge is balanced. Achieve this balanced state by adjusting the Variable Resistorslider until the Galvanometer reads zero and no more current flows through the middle path. Notice how the arrows depicting current direction change as you manipulate the slider. The ohm value is displayed above the slider. By discovering the value of the variable resistor in the balanced bridge, you are able to determine what the unknown resistance at R4 is, with a little math: R1/R2 = R3/R4 or R4 = (R2 * R3) /R1 So by using the above formula we can easily find out the unknown electrical resistance. Derivations:- Derivation of Wheatstone Bridge:-[link 1] First, Kirchhoffs first rule is used to find the currents in junctions Band D: When then I3= Ixand I1= I2(3) Then, Kirchhoffs second rule is used for finding the voltage in the loops ABDand BCD: The bridge is balanced when Ig= 0, so the second set of equations can be rewritten as: .(1) .(2) By dividing equation 1 by 2 we get:- From the equation (3), I3= Ixand I1= I2. The desired value of Rxis now known to be given as: If all four resistor values and the supply voltage (VS) are known, the voltage across the bridge (VG) can be found by working out the voltage from each potential divider and subtracting one from the other. The equation for this is: This can be simplified to: With node B being (VG) positive, and node D being (VG) negative. Bridgeconatianing constant voltage and voltage gage :- A basic Wheatstone bridge circuit contains four resistances, a constant voltage input, and a voltage gage, as illustrated below. For a given voltage input Vin, the currents flowing through ABCand ADCdepend on the resistances, i.e., The voltage drops from Ato Band from Ato Dare given by, The voltage gage reading Vgcan then be obtained from, Now suppose that all resistances can change during the measurement. The corresponding change in voltage reading will be, If the bridge is initially balanced, the initial voltage reading Vgshould be zero. This yields the following relationship between the four resistances, We can use this result to simplify the previous equation that includes the changes in the resistances. Doing so results in the solution for the change in Vg, where h is defined by, Moreover, when the resistance changes are small ( which is the basic equation governing the Wheatstone bridge voltage in strain measurement. The coefficient is called the circuit efficiency. Equal-Resistance Wheatstone Bridge Circuit:- In practice, one often uses the same resistance value for all four resistors, R1= R2= R3= R4= R. Noting that r = 1 in this case, the change in voltage can be further simplified to, By thoughtfully selecting the target and reference resistances, the Wheatstone bridge circuit can amplify small changes in resistance and/or compensate for changes in temperature. How to use the Wheatstone Bridge :- In its basic application, a dc voltage (E) is applied to the Wheatstone Bridge, and a galvanometer (G) is used to monitor the balance condition. The values of R1 and R3 are precisely known, but do not have to be identical. R2 is a calibrated variable resistance, whose current value may be read from a dial or scale. An unknown resistor, RX, is connected as the fourth side of the circuit, and power is applied. R2 is adjusted until the galvanometer, G, reads zero current. At this point, RX = R2ÃÆ'-R3/R1. This circuit is most sensitive when all four resistors have similar resistance values. However, the circuit works quite well in any event. If R2 can be varied over a 10:1 resistance range and R1 is of a similar value, we can switch decade values of R3 into and out of the circuit according to the range of value we expect from RX. Using this method, we can accurately measure any value of RX by moving one multiple-position switch and adjusting one precision potentiometer. Significance of wheatstone bridge :- [link 1] The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate. Variations on the Wheatstone bridge can be used to measure capacitance, inductance, impedance and other quantities, such as the amount of combustible gases in a sample, with an explosimeter. The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low resistances. In many cases, the significance of measuring the unknown resistance is related to measuring the impact of some physical phenomenon such as force, temperature, pressure, etc which thereby allows the use of Wheatstone bridge in measuring those elements indirectly. Applications of Wheatstone Bridge:- [Link 6],[Link 7] A number of resistance measuring devices have been devised on the principle of wheatstone bridge.For example : 1) Meter bridge, post office box and Carey Foster bridge are instruments based on the principle of Wheatstone bridge and are used to measure unknown resistance. 2) A very common application in industry today is to monitor sensor devices such as strain gauges. Such devices change their internal resistance according to the specific level of strain (or pressure, temperature, etc.), and serve as the unknown resistor RX. However, instead of trying to constantly adjust R2 to balance the circuit, the galvanometer is replaced by a circuit that can be calibrated to record the degree of imbalance in the bridge as the value of strain or other condition being applied to the sensor. 3) A third application is used by electrical power distributors to accurately locate breaks in a power line. The method is fast and accurate, and does not require a large number of field technicians. Other applications abound in electronic circuits. Well see a number of them in action as these pages continue to expand. Bridge circuits are widely used for the measurement of resistance, capacitance, and inductance. The resistive bridge, also known as Wheatstone bridge.

Morality Essay example -- Moral Ethics Philosophy essays

Morality   Ã‚  Ã‚  Ã‚  Ã‚  Moral philosophy is very important to the success of an individual. But, before I tell you why moral philosophy is so important, and how it has helped me in my life, let me give you a little background knowledge. Rational knowledge has two components. These components are material and formal. Formal knowledge is not object oriented, and is based on reason. Formal knowledge is logic, or the laws of thought. Material knowledge is object oriented, and has two components. These two components are natural and moral. Natural law is physics. It determines what is the case, and how things behave in nature. On the other hand, moral law determines what things ought to be. Morality is something humans think about, and is not based on physiological factors.   Ã‚  Ã‚  Ã‚  Ã‚  Now that we have a little background of knowledge and moral law, let me tell you why you should lead a moral life. Even though morality is not imposed upon you, it is about humanity. And, while it may not seem fair, in reality, morality is judged by humans. So, if you are immoral, other people will be the ones that notice that you are immoral, and that can hurt personal relationships. One way that I have succeeded throughout my career is by knowing and being friends with a lot of people.   Ã‚  Ã‚  Ã‚  Ã‚  The practical side of life is based on interpersonal relationships. Whether it be social or business, communicating with people is the only way to get things done. There is no way that you can go through life in today's society without getting along with people. If people think that you are immoral, than they will not respect you, or be willing to work with you. Again, it may seem like it is not fair because you know that no one is one hundred percent moral, and if someone doesn't respect you because you are immoral, than they are hypocritical. But, when it comes to moral issues, the reality of the world is that people are hypocritical. They feel it is okay for them to do it, but not okay for anyone else.   Ã‚  Ã‚  Ã‚  Ã‚  Think about it, how many times have you said, "I can't believe that he did that; he's a jerk." Knowing the entire time that you have done the same thing. You may say, "Who cares!" I'm here to tell you that one day you might care. Let me give you and example. After I completed a business venture that made me over one million dollars, I learned that the only reaso... ...Moral law has helped me be successful in everything that I do.   Ã‚  Ã‚  Ã‚  Ã‚  Being a 65 year old man, I have seen a lot. I know the value of moral philosophy. Moral philosophy has helped me be successful in every thing that I have done. You may ask, "How has it helped you be successful?" Well, I have told you a couple of aspects of moral philosophy, and all of these aspects have helped me keep things in perspective. Financial success will come with morality, but if it doesn't, then you will still be better off because you have led a moral life.   Ã‚  Ã‚  Ã‚  Ã‚  There have been times in my life when I have succumb to selfish inclination, and the results were immediately good. But ultimately, if I had been labeled as an immoral person, and was not able to do certain things because people didn't like me, than I definitely wouldn't have been the one invited to give this talk to you. By the way, I am getting paid an awful lot of money for this talk. So there is another way that morality has helped me. Happiness is not a grounding for morality, because some immoral people are happy. But, morality can lead to ultimate happiness and greater success in whatever you attempt to do in life.

The Importance of Babylon :: essays research papers

The name Babylon means â€Å"Gate of God†. The location of the ancient city was along the Euphrates River and today is marked by a long stretch of ruins east of the river. Which is ninety kilometres south of Baghdad, Iraq. This was one of the main trading points of the ancient world because of its central location. Some important events that happened there are things that have shaped the way we live today and we still use the 24 hour day they created this form of counting has survived for four thousand years. Another important event that happened there was the building of the tower of Babel the people built this tower to try and reach Heaven. It was most likely that the tower was used as a place of worship and to create a common religious centre, Gods only merciful alternative was to separate the people into different languages and countries to disable there plans. Because he had also promised himself never to destroy the earth with floods again because of the disobedience of mankind. So the punishment was quite mild compared to the global flood. Archaeologists have dreamed of finding the ruins of the tower but have been unsuccessful. There maybe biblical evidence as to why they have not found this tower of extreme significance. The story is much more than God simply interrupting a building pro ject but it marks the origins of the languages and nations of the earth. Babylon is even home to one of the Seven Wonders of the World, The Hanging Gardens of Babylon. They are in the plalace of Nebuchadnezzar II. The gardens were built on 23 metre tall and being water by a very complicated watering system, the water being provided by The Euphrates River. They were a mountain like series of planted terraces. Excavations have found the elaborate pully system watering the gardens right up to the top terrace.
