Detective Graham in the Movie Crash Essay Example | Topics and Well Written Essays - 1250 words
Detective Graham in the Movie Crash - Essay Example The film literally bursts with the theme of racial prejudice as a multi-coloured cast careens in and out of the screen to make their presence felt. Each character has an issue to deal with regarding his or her ethnic background. For example, the overly- ethnocentric black car robber who constantly complains about how blacks are being unfairly discriminated upon in L.A. reflects a self-fulfilling prophecy. He believes that the white server in the restaurant ignored them because they were blacks and because blacks are not known to give tips, proved her right by not leaving a tip at all, justifying that they had poor service. A while later, he spots a victim in a white woman who avoids their direction. He knows she did so because she thought they were black muggers and was fearful they would rob her. And true to his ââ¬Å"callingâ⬠, the black man and his companion do rob her and her lawyer-husband of their car. Society might have ingrained in these black people how to behave, and they automatically do so even if they think and feel deep down inside it is offensively unfair. However, they play the role society expects them to. It is pathetic to realize that one can be held helpless against societal expectations. These circumstances divide people and turn them against each other. The same goes for the scene where the American gun dealer who gets impatient with foreigners speaking their language in front of him, making him feel left out. Sensing that these Mediterranean customers are Arabs, he snaps at them by saying, ââ¬Å"Play your jihad on your own timeâ⬠. When the customer reacts angrily, saying he is an American citizen who has the same rights as everyone else, the dealer goes on his offensive oration on how these foreigners have no right to destroy America. He is suggesting that the customers are would-be terrorists, relating it to the September 11 terrorist attacks. The man is sent out of the store leaving her daughter behind while the dealer conti nues his hostile verbalizations. In doing so, he is unaware that he himself is terrorizing a lady. Why are people always so angry that they blame such negativity on others by finding faults? Is it true that we are always ââ¬Å"behind metal and glassâ⬠walls that we are inaccessible and hence, untouchable to others? We rely on stereotypes to help us deal with people who are different from us because that is what society expects. Indeed, one canââ¬â¢t help but judge one another based on physical appearances and the stereotypes they represent. Gray (2012) discusses why racial stereotyping is destructive to American society in general. First, it means communicates to the majority of Americans that the negative actions of a few minorities are generalized to the collective values of the whole minority community. This is usually felt by Black American lower to middle-class people who are often adjudged as muggers or criminals. Another effect of stereotyping is that the stereotyped group begins to internalize such negative labels and actually mimic or act out the prejudiced behaviour. This behaviour becomes generalized as typical. The black men in the movie whose self-fulfilling prophecies ingrained by society were adjudged to be so as people are pushed to fulfil those prophecies such as being muggers or criminals. They feel that they have no chance of vindicating themselves from such an unfair perception that they must as well live it.Ã

How the Norman Conquest Affected England and English Essay
How the Norman Conquest Affected England and English Literature--causes, impact, and result - Essay Example Immediately following the Norman Conquest, the religious orthodoxy of England faced a serious threat to their material possessions, as the new rulers ordered despoliation of church treasures, imposition of punitive gelds and taxes, introduced new mandates of knight service, and lay magnates seizure of the estates belonging to churches if they were strong enough to do so. In addition to such strictures, the autonomy and authority of monasteries were undermined, as bishops were bestowed with powers to annex a wealthy monastery. Further, ââ¬Å"the establishment of an Episcopal see in an abbey threatened not only the wealth of the community, which had to be divided to provide for the bishop and his familia, but also the independence and the status of its head, and it is not surprising that communities so threatened resisted vigorously. Tension between religious houses and bishops is a dominant theme in post-Conquest ecclesiastical historiesâ⬠. (Jane Dick Zatta, 2005, p.306) Older historical accounts of medieval England presented a rather simplistic picture. The authors of these accounts do not venture beyond stating the obvious political and cultural transformations of the period. But as the methods of research got more advanced alongside developments in such fields as archaeology and anthropology, revisionist histories and subaltern studies have given new perspectives into English past. As a consequence, such popular interpretations of medieval English history as recorded by the great nineteenth century historian William Stubbs are being revised and rewritten. In Stubbsââ¬â¢ works, for instance, the introduction of French feudalism to England is given a sympathetic treatment. But for contemporary historians, feudalism is a purely exploitative enterprise devoid of civil merits. Similarly, the Magna Carta and the Parliament of the thirteenth century England have now come to be seen

The Sustainability Strategy Challenges Facing Organizations Business Essay
The Sustainability Strategy Challenges Facing Organizations Business Essay Arguably, sustainability is said to be the greatest challenge to the present and future management practices. Dimensions of economic, social and environmental raise the question of meeting present needs without compromise to future generations ability in meeting their needs. For this reason, global environment presently challenge tackling require Non Governmental Organizations, corporate, private, individual, public, non-profit organizations and government sector commitment. Such sectors need to address issues such as environmental efficiency, seizing advantages of developments of renewable energy, satisfying green consumers and business sustainability among others. Every sector need to prioritize in network of global sustainability across multiple practices (Galea, 2004). Similarly, working with industrial associations and policy landscape intense understanding would be significant. Comprehensive models assist consumers establish strategies and appropriate practices which enable com petitive advantages, thereby making business sustainability vital. In addition, the models assist modern managers to device strategies and policies for the environment to facilitate major changes. However, in a bid to achieve sustainability, business communities encounter major challenges. For example, according to findings there are challenges that may be observed on business world, and therefore academic experts or modern managers should find common grounds for competitive reasons (Blcakburn, 2007). Organizations seem to be realizing that issues of sustainability are complex. Therefore, varied perspectives are required in production of innovative solutions. To begin with, one of the major challenges of sustainability is in assigning and measuring value of ecological impacts of a firm. This nvolves eceological footprint where the question is raised on whether carbon footprint is final. Despite firms restless efforts, industrial operations have been observed to have a continued discharge and generation of enormous wastes. Pollution of the natural environment has therefore been inevitable. Such pollution has caused damages to households or other enterprises. For example, in an attempt to ensure sustainability in healthcare organizations the UK government is responsibly operating the states healthcare system. Such operations enable the population to enjoy the benefits related to publically financed Healthcare. U.S government on the other hand provides majority of the privately funded programs. In provision of healthcare for everyone, different countries are now investing in sustainable healthcare because of the current impacts related to change in climate within our environment. Conventional drug use such as herbal drugs would facilitate clean and safe environment. With such, disposals of chemicals related to unavoidable wastages of drug substances via approaches such as burning could be lowered. Consequently, systems of accounting do not ascribe such costs with their sources and neither is the record kept systematically. With an up-ward trend, companies and organizations are being compelled to internalize such environmental costs via stricter environmental regulations and procedures or via damages liability suffered by others. Accurate companys measurement of the true environmental related costs has been offering a huge range of benefits. Correct measurement helps the management to track performance relative to past performance. Similarly, such measurements can offer external investors benchmark who are concerned with performance of the environment by firms plus their finances. In addition, the measurements can evaluate the firms exposure to the environment and financial risk originating from environmental performance. However, despite such measurement benefits, tools to adequately measure the cost are not available (Galea, 2004). For example, Trucost Ltd, a London research firm has created databases fro estimating the externality costs for global largest corporations. Firms emissions or wastes are measured with the use of individual information sources and each emission is given a monetary value through multiplication of its physical quantities by a speculated price. Nevertheless, results from such measurements are usually estimates hence actual measurements are never acquired. Secondly, firms have been facing the challenge of building a sustainability corporate culture which is enduring. Questions are raised in this challenge on what next for the company after key sustainability leaders quit the company. Challenge is on where the firm should begin with such an occurrence. Normally, sustainability initiatives are always associated or linked to few key individuals within a firm, particularly those on leadership potions. When these individuals leave the company, the initiative of sustainability may begin to atrophy. Nevertheless, those firms whose culture of sustainability is strong, the initiatives of sustainability endure for long. Companies experience a challenge in maintaining such a culture and there is need therefore for the firm to consider several aspects. Firms or companys structure need to learn something from safety movement which will act partly as the core culture of majority of manufacturing and extractive firms. Companies must also evaluate the differences between its sustainability and that of other organizational cultures. Similarly, its necessary to establish which practical tools and devices can be applied to embed culture like incentive systems or organizational designs. Thirdly, firms are being challenged to promote and ensure supply chains sustainability. Argument here may involve whether suppliers from less developed countries should be treated differently from those in developed nations. For example, acting as intermediaries between tourism service providers and tourists, tour operators incorporate varieties of services which are tourism related. Such corporations forms full holiday packages which are then marketed to clients via travel agents or directly. Generally, every package consists of accommodation and food provision, transport or even events and activities such as social activities or excursions. Since most of the products or services within the package are provided via supply chains of companies which are subcontracted, agents or organizations or tour operators are not in direct control at all times of the social or environmental effects of such goods. However, consumers always expect firms to always avail quality, environmental friendl y and social sustainable products. Firms are therefore responsible fro ensuring all inputs going into their products are sustained. For effective implementation of sustainability policies, tour operators offering products that are contracted should operate closely with suppliers. Sustainability performance will therefore be achieved all through the holiday package lifecycle. Establishment of such supply chains have been challenging for firms since it requires them to establish coherent company policies with management system in accompaniment. Management systems should however set clear actions and targets for economic, social or environmental performance. Particularly, such challenges arises where management systems are not based on the existing internal processes to maintain implementation costs at lower levels plus promoting integration of all firms operations. Similarly, incorporating employee incentives into sustainability has posed a challenge to companies operations. Firms will always wonder whether existing incentive plans for employees would possibly be connected to goals of sustainability. Normally, only strong practices within organizations prevail. If organizational practices contradict its policies, there is a possibility of green washing. For this reason, firms therefore need to invoke structures and systems that ensure firms practice sustainability. Mangers of sustainability must know the employee incentive plan that can result in companys implementation of the organizational policy sustainability. Challenges faced by firms relate to ways of incorporating targets of sustainability into staff incentives (Blcakburn, 2007). Similarly, they are also challenged in knowledge of what extent context influence applicability or effectiveness of a particular approach towards incorporating the staff incentives to sustainability. Also, limit ation comes in establishing what ways can an existing staff incentive plan be connected to the companys policy of sustainability. Another challenge faced by firms involves identity of business risks which are associated with water shortage and quality. For example, poverty, climate change, malnutrition and water scarcity have posed the biggest challenges to Unilever. However, to address such issues, the company has improvised ways of reducing water use both to the company and their consumers. Similarly, the company has produced an overview of sustainable development in 2008. The publication explores the most material issues of the company such as nutrition, sustainable agricultural sourcing, hygiene and climate change among others. In the overview, an explanation has been offered on the ways of integrating sustainability to Unilevers business or brands. Through such integration, improved health, hygiene and nutrition is reached. Companies may be limited in acquisition of tools or devices in risks evaluation incase of a climate change. According to report released by Global Equity Research group , investors and companies have been swift in identifying opportunities in water-related technologies or business. However, they are slow in identifying the increasing business risks associated with water supply pressures. Firms are limited in knowledge of their firms risks in relation to water and their chain of supply. Similarly, companies have been constrained in acquisition of water conservation or supply contingency plans. Due to this challenge, San Fransisco in California held a 2-day conference which widely featured on risk assessment, water conservation and water recycling. Similarly, Deloitte Touchà © principal in presentation described anticipated water shortage in the future posed serious threats to businesses. Such threats were to face firms that have not developed water supply or conservation contingency plans in the future. Overall consensus revealed that business enterprises particularly those within water intensive industries headed for an increased risk level from supply of water issues globally. Consequently, managers who fail to plan water related risks will ultimately be compelled to address the issues through supply disruptions, diminished quality and increased costs (Blcakburn, 2007). Primarily, business experience challenges or water risks in physical form through disruption or supply reduction. In addition, the limitation is in form of regulatory where firms do not have ability to obtain discharge or use permits. Reputation is also affected due to public perception of the firms use of freshwater or wastewater creation. Industries such as mining, energy food or beverages have more water intensity than others. They are therefore exposed to more water related risks. Another challenge facing the business operations in sustainability is identity of aboriginal perspective on sustainability of business. At the same time determination of the best approaches for engaging aboriginal communities constructively. Aboriginal groups maybe closely tied more to sustainable life ways, the question raised is whether they can offer any teaching to corporations. Aboriginal individuals act as an integral part of the organization. Normally, they form distinctive constituencies which assist in creation and improvement of public perception of firms performance. Long-term good quality and secure supply of raw materials that are competitively priced has been the biggest challenge in organizations and its fundamental in a firms operation. Most companys decisions are based highly on aboriginal individuals needs and perspectives inclusive of resources and public lands. Aboriginal communities provide suppliers, employees, customers or contractors. On the other hand, aboriginal businesses involve a growing business sector with high ability to avail services and goods for the firms operations. Firms are usually limited in providing sound, strategic sense of business in support of aboriginal people involvement. In Canada for example, they have assisted in economic growth and encouraged a proactive work in building mutually beneficial relationships in business with the aboriginal individuals. Many firms have had very positive aboriginal groups interactions and the parties experience symbiotic benefits. However, other business operations under similar regions have experienced negative interactions. Nevertheless, its not clear over what approaches offer the most competitive edge. When firms build more robust understanding of sustainability based on aboriginal perspective, developer and aboriginal community relationship create mutual respect and trust hence positive engagement. Similarly, understanding of this perspective sustainabil ity informs business operations or communities on new sustainability approaches and stakeholder engagement. Such approaches are both within and outside aboriginal communities. In this perspective, questions raised relate to what are the best or worst practices in working with aboriginal communities. Similarly, the perspective seeks to know whether the best practices differentiate by aboriginal group or by sectors and if so, how that happens (Galea, 2004). Lastly, firms experience challenges in measurement of economic impact of NIMBY. Firms are always limited in knowing whether NIMBY claims are justifiable or whether they are valid. Compnys seek to know whether economic values can be assigned claims of NIMBY. NIMBY groups can impede substantially on the progress of a company projects. Although companies maybe aware of the risks linked to NIMBY-ism, challenges exist since it has not been proved whether the claims of NMBY are justified. Questions arise on whether NIMBY-ism can generate any economic value and how evaluations would be made. Similarly, firms seek to know correlation between NIMBY activism and economic impacts that are subsequent, whether positive or negative. In conclusion, we have evaluated the effectiveness of business sustainability and how the seven challenges have impacted on the implementation of such sustainability. Firms need to devise proper ways of tackling such challenges in ensuring proper flow of business operations. Challenges have been revealed to be continued discharge and generation of enormous wastes, incorporating employee incentives into sustainability and ability to sustain corporate culture which is enduring. Similarly, other challenges include promotion and ensuring supply chains sustainability, identity of business risks associated with water shortage and quality. Identity of aboriginal perspective on business sustainability and measurement of eceonomic impact of NIMBY have also been associated with challenges facing sustainability.

They Died With Their Boots On :: essays papers
They Died With Their Boots On Produced in 1943, They Died With Their Boots On, a Warner Brothersà ® film, is a horribly inaccurate account of the events that lead to the Battle of Little Big Horn. His early days in war were depicted accurately, however. Boots told of his experiences at West Pointe; the most important experience is, notably, his graduation. He received the absolute worst scores ever recorded at West Pointe upon his commencement. After that point, it all goes down hill. Custer was also a womanizer, but in this film he was quite a gentlemen, being sure to get Elizabeth Baconââ¬â¢s fatherââ¬â¢s permission for everything the two did together. Custer was displayed as a very sympathetic and warm-hearted general, while he was, in actuality, not such. Custer was known to be rather a large egoist and somewhat of a rude man. Then, for ââ¬Å"dramatic effectâ⬠, filmmakers fabricated a conspiracy that Custerââ¬â¢s ââ¬Å"enemiesâ⬠concocted to remove him from opposition. His opponents, e xecutives of a large company which he refused a position in, ââ¬Å"liedâ⬠about gold in the Black Hills in order to trick thousands of Americans into violating a peace treaty with the Sioux. The truth: there really WAS gold in the Black Hills. Negro slaves were depicted as goofy and silly, added only for comic effect. One lady in particular danced about singing a rhyme, ââ¬Å"Rabbitââ¬â¢s foot, work your charm, protect that ladyââ¬â¢s man from harm!â⬠after reading the ââ¬Å"tea leavesâ⬠for a friend. The Sioux Indians were also depicted rather inaccurately. They all wore a single feather in the backs of their heads and yipped and hollered just as ââ¬Å"Indiansâ⬠would do. They screamed and beat their hands on their mouths, all the while speaking English in the manner of a five year-old. Finally, the filmââ¬â¢s depiction of Civil War battles, not to mention the battle of Little Big Horn, were laughable. There were twenty, MAYBE thirty men all lined u p on either side of the field, and every time the Union soldiers fought, at least two Confederate soldiers or Indians fell, dead. However, when the opposing side fired or attacked, the Union cavalries were nearly impregnable.

Child Development Article Reaction Paper Essay
The article How Your Child Learns by Jeannie Ralston, in Parenting magazineââ¬â¢s September 2006 issue, addresses the different learning and motivation styles of children. According to Jeannie Ralston, there are three learning styles: by listening, looking, or doing. Most children will either rely heavily on one of the learning modes, or use a combination of the three. Children that learn by listening typically are not motivated by pictures, but by sounds and songs. Listening children learn through conversation and jingles. Auditory learners need quiet for concentrated tasks and do well when asked to repeat back ideas to reinforce what has been learned. Visual learners often are described as having photographic memories. Children that learn visually learn well from pictures, videos, maps, models, and charts. Visually oriented children often are so captured by pictures on a page; they have problems concentrating on any one thing. Kinesthetic or doing children learn by using their bodies. This can mean a child needs to move around while thinking or use his fingertips to absorb meaning. Kinesthetic children tend to not be able to sit still for long periods and prefer to act out stories rather than hear or see them on a page. Active learners are easy to spot because they always want to be shown how to do things. Jeannie Ralston posits that there are also three styles that motivate kids to learn: the desire to please you; perfectionism; and competitiveness. Earning praise is the strongest motivator for children with a desire to please their caregivers. The key is to teach the child that pleasing himself is just as important. Some children have a driven desire to master everything and be perfect. These children need to be taught that mistakes are inevitable and that productivity need not suffer in light of mistakes. Competitive children are driven by the ââ¬ËIââ¬â¢ll show youââ¬â¢ streak. These children need to be taught that there are different ways of learning and not everyone will do things the same way. Both learning and motivational styles need to be combined for an effective early childhood learning experience. Combining motivational and learning styles of children allows parents to effectively support their children. I agree with the basic premise of Jeannie Ralstonââ¬â¢s article and feel that most parents do not spend enough time or have the knowledge to figure how children learn and are motivated. Within one family, several children can have completely different learning styles. Children and parents alike are frustrated when presented with the wrong method of learning or motivation. I posit that all children have a combination of the three learning styles, maybe favoring one over the others. In order for a life long passion for learning to be cultivated in a small child, the child needs to be continually positively motivated. Knowing a childââ¬â¢s learning style will allow the parent to formulate learning opportunities that will continually excite the child. If the wrong learning style is presented to the child, the child will quickly loose interest and seek motivation else where outside of the learning arena. With all the current early childhood development research, parents need to understand that learning starts at much younger ages than five when a child starts school. Parents need an awareness of learning styles so that early childhood learning can be maximized. Parents also need to consider that each child will differ and what works for one child, may not work for the next. Parents also need to have flexibility and insight into their children to know when something is not working for the child. Knowing motivational styles will allow parents to ease difficult situations into win-win situations for both the parent and child. In all, Jeannie Ralston gives a good over view of learning and motivational styles. Understanding how oneââ¬â¢s child learns and what motivates them will make parenting and learning an enjoyable and bonding experience. Capitalizing on this research is essential for a life time of learning and bringing out the best in oneââ¬â¢s child.

With a score of 78 points out of a possible 100, Hilton took the leadership position among the seven hotel companies mentioned in the survey. Overall, the hotel industry improved 3 percent to 75, equaling its highest score since 1994. Hilton takes great pride in its ACSI customer satisfaction score, which confirms the results of an unparalleled focus and commitment by the 74,000 team members at our owned and managed hotel properties across the country to deliver the best in guest service,â⬠said Dieter Huckestein, president ââ¬â hotel operations owned and managed for Hilton Hotels Corporation. Hiltonââ¬â¢s portfolio of 2,000 hotels includes Hilton, Doubletree, Embassy Suites Hotels, Hampton Inn, Hampton Inn & Suites, Hilton Garden Inn and Homewood Suites by Hilton.The ACSI is produced through a partnership of the University of Michigan Business School, ASQ, and CFI Group, which measures customer satisfaction in the competitive hotel industry on a regular basis. The ACSI is updated on a rolling basis. New scores for the hotel industry replace those collected one year ago and are added to scores of five other sectors of the economy measured during the intervening year. One sector that didnââ¬â¢t fare well was the airline industry, which dropped 1. percent to 65, its lowest score since the industry was rocked by 9/11. Southwest Airlines still rules the industry at 74. US Airways made the industryââ¬â¢s biggest jump, improving nearly 9 percent to 62. Northwest Airlines, on the other hand, dropped 4. 7 percent to 61, taking last place in the industry as it struggles with strikes and a Chapter 11 bankr uptcy filing. The overall decline was attributed to the airlinesââ¬â¢ struggle with labor contracts, bankruptcies and higher fuel prices, leaving consumers feeling they are getting less for their money.

The Definition of a Dermal Denticle
The Definition of a Dermal Denticle Dermal denticles (placoid scales) are tough scales that cover the skin of elasmobranchs (sharks and rays). Even though denticles are similar to scales, they are actually just modified teeth and are covered with hard enamel. These structures are packed tightly together and grow with their tips facing backward, giving the skin a rough feel if you run your finger from tail to head, and a smooth feel from head to tail. What Dermal Denticles Do The main function of these denticles is for protection against predators, kind of like a naturally occurringà chainmail armor, although in some sharks they have a hydrodynamic function. The denticles reduce turbulence and drag which allows the shark to swim faster and covertly. Some swimsuit manufacturers are trying to replicate sharks denticles in swimsuit material in order to help swimmers cut through the water faster.à Like our teeth, dermal denticles have an inner core of pulp (made up of connective tissues, blood vessels, and nerves), covered by a layer of dentine (hard calcareous material). This is covered with an enamel-like vitrodentine, which provides a hard outer casing. While scales in bony fish grow as the fish gets large, dermal denticles stop growing after they reach a certain size. More denticles are added later as the fish grows.
