Picking Cotton - 1671 Words

Picking Cotton In the past decade, eyewitness testimonies have cast a shadow on what is wrong with the justice system in today’s society. Before we had the advanced technology, we have today, eyewitness testimonies were solid cold-hard facts when it came to proving the defendant was guilty. However, time has changed and eyewitness testimonies have proven to be the leading causes of wrongful convictions due to misidentification.

Jennifer took a leap of faith and chose man number five, which was in fact Ronald Cotton. The authorities confirmed Cotton was who they also believed was the intruder that night. After that day at the station, Jennifer was convinced she had made the proper choice. When it comes to critiquing how the identification information was obtained, several things are considered unreliable. The first mistake of the use of eyewitness testimonies in the Thompson amp; Cotton case was Jennifer was in a state of shock when identifying her assailant.

Ghandi Essay Research Paper government didn free essay sample

Ghandi Essay, Research Paper authorities didn # 8217 ; t O.K. of at all. Armed merely with honestness and a bamboo stick, Gandhi got through demands like a rebait on rent wage to the English land-owners, freedom for the Indians to turn harvests of their ain pick and the constitution of a part- Indian committee to hear grudges from the Indians. The Englishmen allowed these demands without inquiries, # 8220 ; merely to see the dorsum of him # 8221 ; . But Gandhi had greater purposes. They sent Gandhi to imprison several times, but they ever had to let go of him, because he neer used or indirectly caused force or offense. He convinced about everyone that passive resistance additions respect and lessenings hate, but terror-actions and force justifies the atrociousnesss. Now, the Englishmans were acquiring afraid of this small, large adult male. And fright made them unsafe. In the town of Amritsar in 1919, English soliders, armed with guns, attacked and shot to kill 100s of nationalist demonstrators, demonstrators who # 8217 ; s end was, ironically plenty, passive resistance. 1516 demonstrators were killed or wounded. The general said that he wanted to give the Indians a lesson that would hold an impact throughout all of India. The English people and authorities reputiated this awful action and the attitude that prompted it. The slaughter of Amritsar turned Gandhi to direct political protest, and made it possible for him to suggest that possibly it was clip for the Englishmen to travel place for good. Within a twelvemonth he was the dominant figure in the Indian National Congress, where Gandhi challenged the Britishs: # 8220 ; 100.000 Englishmans can non command 350 million Indians if these Indians won # 8217 ; t collaborate # 8221 ; . That was what Gandhi wanted to accomplish when he launched on a policy of noncooperation with the British. Passive resistance and noncooperation would do India independent of the British Empire, and the Indians would see the Englishmen off as friends. The first action of this noncooperation policy was to do the Indians realize that to purchase and utilize cotton vesture made in England made the Indian people unemployed and hapless. But one twenty-four hours a police officer got killed as a direct effect of one of the civil disobedience-marches, and Gandhi felt obligated to abandon entire noncooperation. Despite that Gandhi really stopped a revolution that cold have cost 100s of Englishmens lives, Gandhi was sentenced to gaol, this clip on the charges of promoting the Indian people to noncooperation and civil noncompliance. The Englishmen thought that after a few old ages in gaol, Gandhi would be forgotten. But from the first twenty-four hours he became a free adult male he one time once more fought for a free India. In 1930 Gandhi arranged one of his most celebrated anti-English action: The salt March. This was a reaction to England # 8217 ; s unreasonable salt-taxes. The Indish people are, as all other people, dependant of salt. Many Indians couldn # 8217 ; t afford salt because of the new revenue enhancements. Gandhi gathered 100s of 1000s people, and they all marched towards the Indian Sea to pull out salt from the ocean. First, the British authorities chose to overlook it, but after a piece they tried to halt the action. They arrested 90-100.00 people, and in one presentation the British soliders killed and woun ded 10-20.000 work forces. After the salt-massacre the British imperium # 8217 ; s moral and ethic repute was lost everlastingly ( if there of all time were any ) . India had endured all the inhuman treatments, irrationality and adversity, and the people had neither defeated nor retreated. In everybodies Black Marias, India was now free and independent. It seemed like the British authorities eventually saw that, because in 1931 Gandhi was invited to take part in a government-conference in London, to discourse # 8220 ; the possible independency of India # 8221 ; . But the speaking in England terminals in nil, India is still a portion of the British imperium. Together with his battle for political independency, Gandhi fought to better the position of the lowest categories of society, the casteless # 8220 ; Untouchables # 8221 ; , whom he called untouchables ( # 8221 ; kids of God # 8221 ; ) . He was a truster in manual labour and simple life ; he spun the yarn and wove the fabric for his ain garments and insisted that his followings do so, excessively. He disagreed with those who wanted India to go an industrial state. Gandhi thought that his philisophy, the nonviolent opposition, could be used during World War II. Not without a great figure of causualties and deceases of class, but people ever acquire killed or wounded in wars. In 1942-44, Gandhi was imprisoned for the last clip, after he had demanded entire backdown of the British ( the # 8220 ; Quit India # 8221 ; motion ) . Gandhi was tireless in his efforts to acquire a closer relationship between the Hindu bulk and the legion minorities of India, peculiarly the Muslims. His greatest failure, in fact, was his inability to deter India Muslims, led by Muhammad Ali Jinnah, from making a separate province, Pakistan. When independency of India was eventually achieved in 1947 after dialogues in whitch Gandhi was a chief participant, he opposed the divider of India with such strength that he launched a mass motion against it. This resulted in a ghastly Civil War in India and Pakistan, the Muslims fought the hindues. Millions of people got killed, work forces, adult females and kids were slaughtered. Gandhi couldn # 8217 ; t watch this without action. He started fasting and said he would non eat until he was convinced that the combat would halt, and neer of all time get down once more. And one time once more the people of India listened to Bapu, the state # 8217 ; s Father. The combat stopped and the people swore that they would instead decease than fight once more, noone wanted to see Gandhi dice! Cipher but one. January 30, 1948, Mahatma Gandhi was assassinated in Dehli by a Hindu fiend who erroneously thought that Gandhi was both pro-Muslim and pro-Pakistan. India had lost their male parent, the whole universe had lost one of the greatest and wisest work forces of all time. Gen. George C. Marshal, American Secretary of State, said about Gandhi: # 8220 ; Mahatma Gandhi has become a spokesman for the concience of all world. He was a adult male who made humbleness and simple truth more powerful than Empires. # 8221 ; And Albert Einstein added: # 8220 ; Coevalss to come will barely non believe that such a adult male as this of all time in flesh and blood walked upon this Earth. # 8221 ; Beginnings: The movie # 8220 ; Gandhi # 8221 ; The new Grolier Multimedia Enclycopedia, release 6

Classic Airlines Assignment Example | Topics and Well Written Essays - 2250 words

Classic Airlines - Assignment Example Classic Airlines has enjoyed the benefits of participating in an oligopoly marketplace. In an oligopoly there are few companies that control the entire market. The purpose of this paper is to find a solution to solve the problems at Classic Airline using a nine step problem solving process. Step 1) Describe the Situation Classic Airlines is operating in an industry that has seen a long term reduction in business as a consequence of the catastrophic events of 9/11. Since that terrorist attack the industry has seen a steep rise in operating costs associated with security measures. The volatile petroleum marketplace has made fuel cost the highest cost factor in the airline closely followed by employee costs. As a consequence of external and internal factors Classic Airlines had seen its profitability declined tremendously. Last year the net profit margin of the company was a diminutive 0.11%. The net margin of the company is 2.29% below the industry standard (Dun & Bradsteet, 2011). The marketing department at Classic Airlines is in a complete disaster. One of the largest indicators of failure in the department is reflected in the results of its customer rewards program. The customer rewards program at Classic Airlines experience a 19% reduction in its total members and a 21% reduction in the frequency of purchases by those customers. Customer retention is imperative for the success of a business enterprise. The 80/20 rule states that 80% of business comes from 20% of a company’s customers. The loyalty of the customer has declined significantly which will hurt the ability of the company to stay profitable in the long term. There are internal problems occurring within the human resources of the company. Employee morale is at the lowest point it has ever been in the history of the company. Employee morale is important because when morale goes down so does the productivity of the workers. The worries from the staff are justified and legitimate. One of the vice -presidents, Doug Sheffin who is also a union member, is concerned about the company’s ability to meet its current and future obligations with the employees in the future months. He realizes that the firm may incur into operating losses soon if the firm is not able to turn things around. The company’s ability to pay its short term obligations can be measured by its current ratio (Kennon, 2011). Step 2) Define the Problem    Classic Airlines faces some serious problems that require immediate attention since the future of the company is at stake. Due to the decreasing profitability of the company and the fact the company cannot reduce prices any lower to spur demand the company’s Board of Directors has mandated a 15% cost reduction across all departments within a timeframe of 18 months. The situation is so delicate that if the company does not meet the cost reduction mandate the firm faces the possibility of bankruptcy. The most recent indicator that clearly dem onstrates the firm’s declining performance is the 20% reduction in the customer rewards programs in terms of both number of participants and frequency of purchases by the remaining customers. Step 3) End State Goals The company has several end state goals the firm must achieve. One of those goals is to increase the profitability of the company to reach the industry standard of 2.4% net margin within 18 months. A second end state goal of Classic

Process Improvement Application and Quality Improvements Assignment

Process Improvement Application and Quality Improvements - Assignment Example Most organizations use the quality improvement story, mostly the quality improvement tools to improve service delivery and systems. For example, most hospitals and clinics often collect and use data about the health services being delivered, and statistically analyze the data to report to health authorities. Quality improvement methods are designed to study processes and help in improvement of systems. For instance in health care, students will be familiar with the goal of scientific research, but this only helps in discovering new knowledge but they are less familiar with the quality improvement which is aimed at changing performance. Recently medical students are always encouraged to join teams undertaking improvement activities. Quality improvement activities require managers’ to collect and analyze data generated by processes used in the activities involved and measure improvements. For example, a student cannot study changes in his study habits and the environment he lives in affects him. He will need to data to analyze his study habits problems, and decide the information he needs to measure improvements made by him. Measurement is an important component of quality improvement because it forces managers to look at what they do and how they do it. They commonly use the total quality management tools such as; flowcharts, cause and effect diagrams, Pareto charts and run charts. In the past years, quality improvement methods have been emphasized. This includes the identification of a process that has less than ideal outcomes, attaching measures to key performance attributes, analyzing devise approaches, integrating redesigned approaches the process and having checks to determine if the process was successful. Apart from total quality management, other quality improvement strategies are; international organization for standardization ISO 9000, Zero defects, Six Sigma and Toyota production system.
