Wagner Dodge Retreats in Mann Gulch Case Study Example | Topics and Well Written Essays - 2000 words

Wagner Dodge Retreats in Mann Gulch - Case Study Example Interaction between team members and the team leader plays an important role in assessing existing situations, understanding the need of the time and effective resolution of existing problems. The case study of Wagner Dodge provides interesting insights into these aspects of leadership and how certain situations test the leadership abilities of an individual. Background Wagner Dodge headed a fire fighters team of 15 into Mann Gulch, a remote place in Montana to control a huge fire that had broken out in the prairies region. Dodge was an experienced fire fighter and he was responsible for putting out the prairie fire. The team was flown to the area and parachutes were used to drop them down to the fire affected region. However, on landing in Mann Gulch, the team realized that the fire was more aggressive than they had initially thought. The flames were catching on at great speed and there was no escape route since the radio with one of the team members had broken on landing and the ma p was lost too. Left with no possibilities of surviving the fire, Wagner lit a fire and let the area burn out before he landed himself in the middle of this fire circle to protect himself from the prairie fire. He signaled him men to follow him but only one of them joined him in the circle of fire. The rest of the team members did not trust his decision and felt that it was crazy to go into the fire circle started by Wagner. Thus, 13 members out of the 15 perished in the prairie fire (Useem, 1998). Wagner Dodge – decision making and leadership The Mann Gulch fire incident raises a number of pertinent questions relating to the team behavior and understanding existing between Wagner Dodge and his team members. Why did they choose not to follow him and how could the team be unaware of the ground realities? The first question strongly raises doubts over the capabilities of Wagner Dodge as a leader and the lack of trust existing between the chief and his team members. His order to his team to stick to the burned area were met with disbelief and anger from most of the team members and each of them decided to escape the fire in their own ways. The results were tragic and there was nothing much that Dodge could do at the moment to convince them his ways. A review of the situation reveals that though Dodge was a good and experienced firefighter, he had very limited success in achieving the trust and confidence of his team members. He failed to articulate his thoughts and plans in an effective manner to the team members. His inability lay in the fact that he did not communicate emergency plans and guidelines that the team members could follow in such situations. The crew was fairly inexperienced or they would have realized the potential escape route offered by Dodge. If Dodge had explained some possibilities and means of surviving such emergencies earlier, probably all 15 could have been saved from the prairie fires (Useem, 1998). Wagner Dodge also failed to comm unicate the effectiveness of the burnt patch of ground to his team members at the critical hour. This could be associated with lack of time to explain the details to the team members and the inability of the team to grasp in times of the pending crisis.

Traffic congestion Essay Example for Free

Traffic congestion Essay Introduction Traffic congestion is one of the most compelling global problems especially in developed cities. London is among those cities which suffer from the traffic problems. According to the London city council, Londons population was 8. 17 million in 2011. By the year 2011, every 100 people in London owns 60-65 personal cars, which means cars have been the prior transportation tools for local people (Blythe, 2005). Frequently using cars as vehicle contributes to the traffic problems. As the rapid growth of population, the rate of car ownership would reach to a higher level hich is a severe test to the environment. According to Hickman et al (2010), Approximately 25% of carbon dioxide(C02) emissions is contributed by transport tools. Obviously, traffic problem is a magnificent cause of the environmental damage. Although some relevant policy has been implemented to reduce the congestion, traffic problems still exist across the capital with the growth of population and employment. (Transport Committee, 2008) According to Transport Committee (2008), Londons traffic speeds are below average speeds of global cities such as New York nd Singapore. Meanwhile, the population and the demands of Jobs in London are predicted to reach to a high level by 2025. The location of the additional Job will force a large number of people to go through the city at peak hours, which is a severe challenge to the local traffic situation. (Transport Committee, 2008) Thus, light rail transit systems (LRT) could be the ideal solution to traffic problem. However, the high cost might limit the scale of this method. Electronic toll collection system (ETC) is regarded as another option with relatively low cost.

Global Warming Essays -- Greenhouse Effect Climate Change

Global Warming The glass windows of a greenhouse lets in sunlight. The sunlight warms up objects inside the greenhouse. These objects then give off heat. The glass of the greenhouse, however, does not let out the heat. If the greenhouse lacks ventilation, all the heat stays locked inside and the temperature rises. This greenhouse effect also causes the inside of an automobile to become hot if its windows remain closed on a sunny day. The Earth and its atmosphere are like a giant greenhouse. Like the glass windows of a greenhouse, the atmosphere is nearly transparent to shortwave and visible solar radiation. Part of the energy absorbed by the Earth is radiated to the atmosphere as long-wave infrared radiation. Because it contains carbon dioxide and water vapor, which absorb much of the long-wave radiation before partially reradiating it back to the surface, the atmosphere is not completely transparent to this long-wave radiation. This causes the Earth and its atmosphere to warm up. Variations in the amounts of carbon dioxide and water vapor in the air can have a significant effect on how much heat is retained by the atmosphere. The total amount of carbon dioxide present in the Earth's atmosphere remained nearly constant until the 20th century, when the burning of fossil fuels such as coal, fuel oil, gasoline, and natural gas began to release large quantities of carbon dioxide into the atmosphere. The combustion of fossil fuels brought about an ever-increasing ri...

AP ® WORLD HISTORY 2010 SCORING COMMENTARY Question 3 Overview The intent of the question was for students to pick two of the stipulated empires — Han China (206 B. C. E. to 220 C. E. ), Mauryan/Gupta India (320 B. C. E. to 550 C. E. ), Imperial Rome (31 B. C. E. to 476 C. E. ) — and compare the ways those empires exerted political control over their populaces.Students were explicitly told to discuss both similarities and differences in methods of political control. Sample: 3A Score: 8 The essay contains a valid thesis in the second and third sentences of the first paragraph (1 point). In the fourth paragraph, the essay addresses a similarity (â€Å"Both empires had unstable borders†) and several differences, including â€Å"However, Han China dealt with the Turkic Huns through the tribute systems, thus placating them with gifts and avoiding costl y & expensive warfare, which Rome preferred when dealing with their enemies† (2 points).Although there is ample evidence for the Han, Roman evidence is limited by discussion of the Republic, which could not be counted. There is, however, enough evidence for 2 evidence points. In addition to the direct comparison listed above, there is another difference at the bottom of the second paragraph — â€Å"However, because there was less emphasis as a collective group in Rome, the political organization was a lot less structured than China’s† — which earned 1 point for the comparison and 1 point because the statement also involves an analysis.This essay contained a complex thesis, sufficient depth of comparison, and supporting evidence to earn 1 Expanded Core point. Sample: 3B Score: 6 This essay contains a valid thesis in the first paragraph (1 point) and addresses both similarities and differences (2 points). There is sufficient evidence for both the Maur yan/Gupta and the Han empires (2 points). The direct comparison is found in the second paragraph: â€Å"Han China and Maurya Gupta [sic] both consolidated their power through military buildup† (1 point).The essay attempts analysis in the next to the last paragraph but only analyzes the Han: â€Å"Due to their lack of a devout religion, China was able to assimilate the Huns when they began to invade China. † There is no analysis of a comparison of Han and Mauryan/Gupta methods of political control. Sample: 3C Score: 3 There is no valid thesis because the essay attempts to show a difference between Han and Rome in terms of the Roman Republic, which is outside the time period. The essay only addresses similarities, not valid differences (1 point).The evidence is sufficient for the Han, but the only valid piece of evidence for Rome is the statement that â€Å"He [Augustus] defeated Cleopatra and Mark Anthony making sure that Rome is politically secured† (1 point). M ost of the Roman evidence is prior to 31 B. C. E. and therefore did not earn credit. The essay has a valid direct comparison in the fourth paragraph: â€Å"The size of both empires was an issue that led to leaders ultimately losing political control of both empires† (1 point).  © 2010 The College Board.

Gladiator: Critical film essay Essay

Ridley Scott’s Gladiator is the critically acclaimed 2000 film starring Russell Crowe which won forty-eight awards, including a BAFTA for best film. Gladiator depicts the tale of Maximus Decimus Meridius and his struggle against the might of the Roman Empire and the vicious gladiatorial arenas. Throughout Scott’s masterpiece are a wide range of filmic techniques in the visual and auditory channels that collaborate in enunciating the overall narrative. The opening sequence is a prime example that uses Mise-en-scene, lighting, costume and film speed to enunciate the key scene. The opening scene begins with some historical information that introduces the audience into the scene and sets up the narrative. Scott informs his audience on the vast scale of the Roman Empire, â€Å"One quarter of the world’s population lived and died under the Caesars.† The emphasis is on â€Å"and died† in order to set the scene for the incoming battle. The Universal and Dre amWorks logos are in a sepia colour. This colour informs the audience that the film is set in the past due to it being used for old photographs and ink. The historical information is accompanied by calming, serene music which leads to the first view of the protagonist. Scott has made use of coloured lighting, incorporating gold (which is representative of the wealth the Roman Empire had) in many scenes throughout the film. The colour gold is an interesting choice because it represents peace and riches which could also be a reference to the Roman afterlife Elysium. Scott has used Mise-en-scene in the first shot of the protagonist, brushing his hand in the corn field. Although the audience are only presented with an extreme close up shot of his hand; they learn about his character through Scott’s control of what appears in the frame. The audience sees a wedding ring on his hand and so learn that he is a family man. The critic John Gibbs also comments on Mise-en scene, â€Å"the contents of the frame and the way they are organised.† During the close-up of the protagonist’s hand, the audience can hear a diegetic sound of the wheat blowing. A non-diegetic sound of children playing and soothing music can also be heard which again tel ls the audience he is a family man with something to loose. The consonant tone of music and golden cornfields set up an idyllic scene of calmness which instantly contrasts when the frame cuts to a harsh, cold and dark Germanic battlefield. The camera uses a medium close up of Maximus’s face which reveals the emotions of a tired soldier. Maximus catches a glimpse of a red  robin which symbolises his near return home to the summer and his family. The robin’s red breast could also be a signifier of the forthcoming bloodshed. When Maximus moves on to greet his army a long shot is used which displays him walking alone. The theme of isolation comes into play which also recurs throughout the film. As the battle scene draws near, a high angle long shot is used to display the mighty Roman army. Costume is used a great deal in Gladiator and adds to the films authentic feel. A medium close up shot is used for the first time on Emperor Marcus Aurelius which shows him wearing rich clothing and surrounded by knights. This scene only lasts a few seconds but the audience discover he is a man of importance through costume. Moreover, Scott wanted Maximus to appear as a strong character that holds high authority as an important character. This is achieved through costume as Maximus’s armour is bigger than all other characters and has different insignias weaved into it. The costume for the barbarian army is rather contrasting to that of the Roman Empire. The barbarians are dressed in rugged cloth which suggests they are not nearly as advanced or wealthy as the Roams who wear steel armour. A Critical Introd uction to Film highlights the importance of costume, â€Å"Costume provides information about time and place, but, more importantly, they express social milieu and personal style.† At 04:41 the barbarian leader steps forward from his army and lunges the head of the Roman messenger into the swampy ground and disrespects the Roman army. This is a casual chain of events that help drive the plot forward, â€Å"Film narration moves forward by a succession of events linked in a casual chain.† It is evident that the Roman army will fight now and Maximus kneels down to run dirt through his hands which is a recurring motif. The motif shows the spiritual side of Maximus, he asks the gods to fight beside him. As Maximus kneels down the audience are given a Point of View shot through Maximus staring into a dog’s eyes. The dog symbolises the brute force of Maximus and suggests he is a wild character. As Gladiator mounts his horse the music quickens and a non-diegetic drum beat begins to enunciate the battle scene. The music increases pace as the battle almost begins which heightens audience’s tension and excitement. As the battle begins a wave of Roman arrows are dispersed and computer generated imagery showcases a variety of special effects. A long range establishing shot on a high angle displays the dest ruction that the Roman Empire is unleashing. As  Gladiator rides with his cavalry there is an array of fast cutting shots that last a few seconds each. The fast paced shots give the audience a battle like feel with exaggerated sound effects of swords clashing and explosions. Maximus demonstrates his leadership role by shouting commands like, â€Å"Stay with me† and â€Å"Hold the line† . After the establishing shots of the battle Scott includes scenes that are more subjective to Gladiator. The gory battle follows Maximus as he enters a slow-motion phase that displays his disorientated point of view of the battle and a montage of his men fighting. Furthermore, the dog also engages in battle which suggests he is strong and independent like Gladiator. Ridley Scott’s Gladiator incorporates brilliant techniques that contribute in enunciating the opening sequence. These techniques are things such as the use of costume which generates an authentic feel and camera speed which demonstrates a terrifying battle. A strong use of Mise-en-scene shows how the narrative develops through camera lighting and casual chains in the plot.

How to become a veterinary receptionist

How to become a veterinary receptionist Healthcare careers are a hot ticket these days- but that’s not just human healthcare. The veterinary industry is also growing, with job openings in clinics and facilities that take care of our furry (and aquatic/scaly/feathered) friends. If you find yourself more drawn to animal patients than human patients, then becoming a veterinary receptionist could be a good option for your administrative career.What does a veterinary receptionist do?A veterinary receptionist’s job is pretty similar to most receptionist jobs. These administrative professionals may be responsible for being the face of the veterinary office, handling the daily traffic in and out of the practice.A veterinary receptionist’s day-to-day responsibilities may include:Answering phone callsScheduling appointmentsGreeting patients (and their humans)Arranging for follow-up careTaking patient informationUpdating and filing patient chartsAssisting with pet supply purchasesProcessing payments and insurance informationMaintaining the waiting roomVeterinary receptionists often work standard full-time hours, though nights and weekends may be required for emergency vets or animal hospitals that provide round-the-clock care.What skills do veterinary receptionists need?Veterinary receptionists need to have a combination of administrative skills and clinical knowledge, since they’re working in a medical environment.Skill with animals:Â  This is a must, given the nature of the daily work of a veterinary receptionist. You don’t have to love all creatures great and small, but it helps- and being afraid of patients who come through the door can lead to more stress and unhappiness than you would want out of your job.Skill with people:Â  Yes, animals are the patients, but they almost always come with humans in tow- humans who may be nervous wrecks about their animal family members’ health concerns. Being friendly and customer service-oriented is a very helpful skill for vet erinary receptionists to have, even when the focus is on the animals.Knowledge of medical/veterinary terminology:Â  A veterinary receptionist should be well-versed in the medical terms and general knowledge that is specific to the vet’s office. The receptionist is often taking down preliminary information about a patient’s condition and recording it in a chart, so there needs to be a strong base of knowledge about pet care and animal medical needs.Organizational skills:Â  Depending on the size of the veterinary practice, the receptionist may be the only front-line defense for the entire office. That means being able to organize all incoming information (like phone calls, messages, appointments, arriving patients, etc.) in a way that helps the practice run smoothly.Tech-savviness:Â  Like any modern medical practice, a vet’s office increasingly relies on digital technology to make appointments, store patient information, and handle incoming calls. The veterinar y receptionist should be able to tackle things like email, digital record management, and digital or multi-line phone systems in order to do the job efficiently.What do you need to become a veterinary receptionist?A high school degree is typically sufficient for this job, although some veterinary receptionists also have some schooling or degrees in an administrative or animal-related field. Direct experience working with animals is a major asset if you’re looking for a job in this field.How much do veterinary receptionists make?According to the U.S. Bureau of Labor Statistics, receptionists in general make a median annual salary of $27,920, or $13.42 per hour.What’s the outlook for veterinary receptionists?Receptionist jobs in general are expected to grow about 9% by 2026 (about average), per the U.S. Bureau of Labor Statistics. However, healthcare-specific careers, including veterinary roles, are expected to grow at a much faster rate, so this specialty is expected to grow faster than average as well.One of the best things about a job in the healthcare industry is that you can find a niche for your interests and experience. And if you’ve always liked animals a little more than humans (it’s okay to admit that here!), becoming a veterinary receptionist could be a great way to parlay your administrative skills into a job where you get to greet and pet dogs and cats every day.

The Biography of Francisco Morazan

The Biography of Francisco Morazan Jose Francisco Morazan Quezada (1792-1842) was a politician and general who ruled parts of Central America at different times during the turbulent period from 1827 to 1842. He was a strong leader and visionary who attempted to unite the different Central American countries into one large nation. His liberal, anti-clerical politics made him some powerful enemies, and his period of rule was marked by bitter infighting between liberals and conservatives. Early Life Morazan was born in Tegucigalpa  in present-day Honduras in 1792, during the waning years of Spanish colonial rule. The was the son of an upper-class Creole family and entered the military at a young age. He soon distinguished himself for his bravery and charisma. He was tall for his era, about 5  feet 10 inches, and intelligent, and his natural leadership skills easily attracted followers. He became involved in local politics early, enlisting as a volunteer to oppose Mexico’s annexation of Central America in 1821. A United Central America Mexico suffered some severe internal upheavals in the first years of independence, and in 1823 Central America was able to break away. The decision was made to unify all of Central America as one nation, with the capital in Guatemala City. It was made up of five states: Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica. In 1824, liberal Jose Manuel Arce was elected president, but he soon switched sides and supported the conservative ideals of a strong central government with firm ties to the church. At War The ideological conflict between liberals and conservatives had long been simmering and finally boiled over when Arce sent troops to rebellious Honduras. Morazan led the defense in Honduras, but he was defeated and captured. He escaped and was put him in charge of a small army in Nicaragua. The army marched on Honduras and captured it at the legendary Battle of La Trinidad on Nov. 11, 1827. Morazan was now the liberal leader with the highest profile in Central America, and in 1830 he was elected to serve as president of the Federal Republic of Central America. Morazan in Power Morazan enacted liberal reforms in the new Federal Republic of Central America, including freedom of the press, speech, and religion. He limited church power by making marriage secular and abolishing government-aided tithing. Eventually, he was forced to expel many clerics from the country. This liberalism made him the implacable enemy of the conservatives, who preferred to keep the old colonial power structures, including close ties between church and state. He moved the capital to San Salvador, El Salvador, in 1834 and was re-elected in 1835. At War Again Conservatives would occasionally take up arms in different parts of the nation, but Morazan’s grip on power was firm until late 1837 when Rafael Carrera led an uprising in eastern Guatemala. An illiterate pig farmer, Carrera was nevertheless a clever, charismatic leader and relentless adversary. Unlike previous conservatives, he was able to rally the generally apathetic Guatemalan Native Americans to his side, and his horde of irregular soldiers armed with machetes, flintlock muskets, and clubs proved hard for Morazan to put down. Defeat and Collapse of the Republic As news of the successes of Carrera came to them, conservatives all over Central America took heart and decided that the time was right to strike against Morazan. Morazan was a skilled field general, and he defeated a much larger force at the battle of San Pedro Perulapan in 1839. By then, however, the republic had irrevocably fractured, and Morazan only effectively ruled El Salvador, Costa Rica and a few isolated pockets of loyal subjects. Nicaragua was the first to officially secede from the union, on Nov. 5, 1838. Honduras and Costa Rica quickly followed. Exile in Colombia Morazan was a skilled soldier, but his army was shrinking while that of the conservatives was growing, and in 1840 came the inevitable result: Carrera’s forces finally defeated Morazan, who was forced to go into exile in Colombia. While there, he wrote an open letter to the people of Central America in which he explained why the republic was defeated and laments that Carrera and the conservatives never tried to really understand his agenda. Costa Rica In 1842 he was lured out of exile by Costa Rican Gen. Vicente Villasenor, who was leading a revolt against conservative Costa Rican dictator Braulio Carrillo and had him on the ropes. Morazan joined Villasenor, and together they finished the job of ousting Carrillo: Morazan was named president. He intended to use Costa Rica as the center of a new Central American republic. But the Costa Ricans turned on him, and he and Villasenor were executed on Sept. 15, 1842. His final words were to his friend Villasenor: â€Å"Dear friend, posterity will do us justice.† Legacy of Francisco Morazan Morazan was correct: Posterity has been kind to him and his dear friend Villasenor. Morazan is today seen as a visionary, progressive leader and able commander who fought to keep Central America together. In this, he is sort of the Central American version of Simon Bolà ­var, and there is more than a little in common between the two men. Since 1840, Central America has been fractured, divided into tiny, weak nations vulnerable to wars, exploitation, and dictatorships. The failure of the republic to last was a defining point in Central American history. Had it stayed united, the Republic of Central America might well be a formidable nation, on an economic and political par with, say, Colombia or Ecuador. As it is, however, it is a region of little world importance whose history is most often tragic. The dream is not dead, however. Attempts were made in 1852, 1886 and 1921 to unite the region, although all of these attempts failed. Morazans name is invoked anytime there is talk of reunification. Morazan is honored in Honduras and El Salvador, where there are provinces named after him, as well as any number of parks, streets, schools, and businesses.

Pay for Performance Research Paper Example | Topics and Well Written Essays - 500 words

Pay for Performance - Research Paper Example Therefore, effectiveness of pay for performance can be measured with surveys aims at findings about employee satisfaction and motivation levels (Gomez-Mejia, 2010). Furthermore, their on job performances and achievement of their goals may also help in knowing that whether or not certain pay for performance program is effective. Lastly, financial numbers and ratios, such as revenues, sales, expenses, profitability, operating income, profit margins, return on investment and others remain as major tool to measure their effectiveness. If any pay for performance plan is motivating employees but not adding to the financial success of the company then it is better for the company to revisit the plan and the processes (Schuler & Jackson, 2007). There are many advantages of pay for performance programs for the employees and that is why many companies opt for it. First, by paying employees for their efforts and performances, employers motivate them to improve their performances in order to ear n more (Gerhart & Rynes, 2003). Despite the fact that money is not the only motivator, it is biggest motivator, which means that employees are highly likely to work harder and bring more profits to the company to earn more.

Impact of Educational and Drug Prevention Programs Research Paper

Impact of Educational and Drug Prevention Programs - Research Paper Example From the discussion it is clear that  community policing on the other hand is the partnership of civilians with the law enforcers to curb criminal activities. In this endeavor, the civilians are key players in ensuring that the law is followed and play as allies of the police. This happens at the most basic neighborhoods and is therefore at a small scale. The Deterrence Theory brings forward the notion that human beings abide by the law because of the fear of prosecution for failure to adhere. This brings about the matter of Specific Deterrence which refers to a crime prevention technique which operates on instilling fear on the individual receiving punishment.This study stresses that  the Narconon program from 1966 to the present day has played a role in getting people off drugs and it has centers in averagely 45 countries worldwide. The Narconon drug prevention and education curriculum intends to bring forth more risk factors than benefits of using drugs to young people. The pu rpose of this is to provoke a certain line of reason that the youth are intended to capture. Keeping in mind that among the uses of drugs there is the beneficial aspect like fitting in with a popular crowd or overcoming shyness. This program means to provide an alternative that will effectively counter the drugs.  The Narconon drug prevention staff can boast of educating an aggregate of 5 million school going children on this issue.

Anchor and mooring systems Essay Example | Topics and Well Written Essays - 2250 words

Anchor and mooring systems - Essay Example Anchor and mooring system are used to hold the ships and the floating platforms in position and prevent movements caused by the wind and current. Given most sea vessels and ship are incapable of breaking, only anchorage systems and mooring can be used to slow down and hold the ship into position to avoid moving (Lekang, 2007). The unregulated and unwanted movements caused by wind and the current can cause grave consequences and repercussions including damage to property if the ship is not properly anchored or moored. Floating production systems and offshore drilling units located in deep sea require a high level of anchorage in order to maintain a firm position against the high tides, currents and wind present at high depths. Anchoring systems and mooring therefore perform a crucial function in maintaining the stability of the sea vessels without which there exist costly ramifications (Blackwell & Blackwell, 2011). This paper discusses the operation of anchors and mooring systems, th eir fabrication and classification. Operation Anchor and mooring system consist of the anchor, the mooring line which is used to transmit force from the moored vessel to the anchor and the tension system or the attachment point on the moored vessel or floating work platform. The mooring line can be made from either a chain or wire rope. In some cases the anchor line is made from the combination of the chain and wire rope with fiber line or rigid element included (Blackwell & Blackwell, 2011). In shallow waters of depth up to 100m, chains are usually preferred for permanent mooring. Steel ropes have a higher elasticity and is preferred at greater depth than 300m. Synthetic fiber ropes on the other hand is the lightest among the three choices and is used for anchorage in deep waters of up to 2,000m. The anchor usually provides the majority of the holding capacity or the resistance to motion even though the other components of the system are also at play in contributing to the anchorag e of the vessel or the floating work platform (Dokkum, 2010). The portion of the anchor buried under the sea has a significant contribution to the whole system especially when a chain is used as an anchor line. The portion of the anchoring system excluding the attachment point on the vessel or the floating work platform is known as the ground leg. The ground leg is inclusive of the anchor, anchor line and other auxiliary devices (Blackwell & Blackwell, 2011). The anchor line (chain or wire rope) is connected to the windlass mounted on the sea vessel or the floating platform. The windlass can be either of vertically or horizontally designed. Most anchor and mooring systems use a vertically designed windlass mostly known as a cap an. The capsan is composed of a gypsy; drive wheel notched in order to fit the chain links. The chain is drawn along the deck from the capsan through a pawl and dropped down through the hawse pipe in the deck which exits at the ship's bow. The chain is then d ropped down and a shackle is used to connect the chain to the anchor. The hardened steel pins of the shackle pass through a hole drilled in the anchor central shank (Scott, 2011). Material and methods of fabrication A number of materials can be used to make an anchor ranging from large blocks of rocks to sacks of sand. Commercial anchors are made from pig iron which are fabricated to form cast iron anchors. Steel anchors are also made through drop forging of carbon steel. Both the cast iron and forged steel anchors

The Evolution of Linux - Research Paper Example This document focuses on the evolution of Linux since its establishment to the present version. The main reason for discussing the development of Linux is to understand various changes that have occurred in Linux. In addition, studying the evolution of Linux is of importance to planning for future development of the computer system. The origin of Linux can be traced back to the establishment of UNIX in 1969. UNIX was developed and created at Bell Labs in the process of developing a simple system with recyclable code. However, the primary development of Linux occurred in 1991. Linux was initially developed as a self-contained kernel by Linus Toverlds with a goal of enhancing UNIX compatibility. Development and evaluation of Linux have extensively relied on user collaboration and experience with the operating system from many parts of the world. The system is designed to operate reliably and efficiently on common personal computer hardware although it can also run on other platforms (Silberschatz, 2002). Linux has undergone evolution from one version to the other since it was developed. The first version of the Linux Kernel is Linux version 0.01. The version was developed in May 1991 by the Linux developer Linus Toverlds. Linux version 0.01 had limited features and was limited to specific processors and hardware. The version was only operating on PC hardware and 80386-compatible Intel processors. In addition, Linux version 0.01 was only supported by the Minx file system. It was also difficult to network with the Linux version 0.01 because it had no networking capability (Silberschatz, 2002). On October 5th, 1991, Torvalds released a better version of Linux known as Linux version 0.02 that required Minix to run. However, it received more attention than Linux version 0.01. The kernel improved rapidly within the year, and large number of users and volunteers communicated through social media on the internet. In December 1991, an operational,

Philosophy, The Ultimate Knowledge and Wisdom Essay

Philosophy, The Ultimate Knowledge and Wisdom - Essay Example Numerous writers, philosophers, thinkers and the life have attempted to delve into this subject, to gain the wisdom that one yearns for. This essay attempts to highlight the spiritual quest and knowledge provided by Plato and Thoreau, in their books 'Socrates' and 'Walden Pond', respectively. The approaches adopted by both these great thinkers, vary considerably and it is this variation that diversifies one's thinking and contemplation over the different paths chosen, that enriches our reading experience and knowledge, as well. Plato's 'Socrates' does put forth the teachings of the Greek philosopher, in the form of dialogues between him and his pupils. Through this book, he put forth his philosophy that in one's life, man must be virtuous and true to ethics and morals. When faced with duality of circumstance, he must most certainly choose the path that leads to an ethical conclusion. He says that 'Virtue is Knowledge'. One is considered knowledgeable when one knows what is virtuous. If one knows what is virtuous, one would follow the virtuous, which is morally acceptable.

Business environment Essay Example | Topics and Well Written Essays - 3250 words

Business environment - Essay Example The following graph shows the example of perfect competition Monopoly: Monopoly is totally opposite to perfect competition. In perfect monopoly, only one manufacturer or supplier exists but in reality, such sort of market hardly exists because in such an advanced arena there must be a substitute of each product. There is a dominance of one firm on overall market, such firm can influence prices, lack of substitute, very high barriers to entry (Wilkinson, 2005). Example of such market structure can be a cable company in India, electricity supplier in many countries including Pakistan, and British Telecom. The following graph represents the monopoly market: Monopsony: In monopsony, firmshavethe power to employee factors of production and each firm employee a miniature amount of employees in order to influence the rate of wages. In such market, only one buyer of a particular sort of laborexists. Firms are wage makers because labor has fewer options (McConnell, 2012). Due to the highest bargaining power, firms have lower manufacturing cost and, therefore, largest profit margin.Example of such firms is the electricity generator because it can negotiate a lower price of gas and coal supply contract. Low cost airline gets favorable price for new fleet, food retailers use their bargaining power when purchase items from milk producer, farmer, and other dealers. The following graph shows the example of monopsony market. Oligopoly: In oligopoly, competition exists between few firms. May the industry have the largest number of firms however;few larger firms dominate the overall industry. Firms are liable to manufacture or supply differentiated or standardized products, such firms have to face high entry barriers, have medium power to affect the market price (Wilkinson, 2005). Example of oligopolistic market is the sports apparel industry. Multiple manufacturers exist in sports apparel industry, but some majors like Adidas, Puma, and Nike are dominating the overall

Happy Ending by Margaret Atwood Essay Example for Free

Happy Ending by Margaret Atwood Essay In this essay, I examine the short story, â€Å"Happy Endings,† by Margaret Atwood and how the Canadian author tackled the topic of love and the different ways it is portrayed in relationships and marriage, as well as examined writing styles as used in the story. For my conclusion, I will elaborate on the importance of love and romance in making marriages last as well as emphasize on the cruciality of coming up with an original and authentic literary work. In this story, Atwood focused on both the mechanics of writing and the effects of gender stereotyping, as well as challenged writers who rely on the stereotypical characterization of men and women and to the reader who accepts such gender typing. At the same time, she challenged other writers to more closely examine typical literary convention. Happy Endings has six story versions that present a different scenario of what Through analysis of â€Å"Happy Endings† by Margaret Atwood happens to the main characters, John, Mary, Madge and Fred. Three main themes surface from this story. These themes are that the story depicts middle-class values; portrays marriage and romance; and illustrates writing conventions. Touching on middle-class values, Atwood represents these values in her story as an element of the society. In doing so, the characters in the story manifest them even in the more troublesome aspects of the stories. In tackling marriage and romance, the story revolves around the fulfillment that marriage brings. Using material success and ease of life as the criteria to define a successful marriage, John and Mary certainly have built one. Romance, on the other hand, also emerges as an important theme. The various versions of the story mimic the trajectory of cliched romance novels, which end with the hero and the heroine living happily ever after. Atwood also parodies some typical plots of romantic novels, which include murder, suicide, infidelity, and disease. Lastly, Atwood also dealt with writing conventions in the story by way of experimentation. Atwood’s text in the story is self-referential as she explicitly refers to events that have happened earlier on, as well as the mechanics and elements of writing. Both directly and indirectly, Atwood addresses the whole notion of how an author develops a story. In addition, Atwood’s work also challenges writers to compose authentic works. From the above information and opinions, I conclude that for a more different and effective way of writing, authenticity is important for writers to value. I also conclude that love in marriage or any kind of relationship needs romance to be its companion in order for these relationships to last as romance is the oil that keeps friction from wearing out the relationship.

Cellular and Mobile Communications Technology

Cellular and Mobile Communications Technology LUCAS A. EPPARD HISTORY OF GSM At the 1982 Conference of European Post and Telecommunications (CEPT), the standardization body, Groupe Speciale Mobile, was created to start work on a single European standard. The name of this standard was later changed to Global System for Mobile Communications (GSM). GSM is a wide area wireless communications system that uses digital radio transmission to provide voice, data, and multimedia communication services.[1] A GSM system manages the communication between mobile telephones, radio towers, and interconnecting switching systems. The development of the GSM specification began later that year, with the first commercial GSM system later being deployed in 1991. By 2004, there were over a billion GSM subscribers in more than 205 countries and territories across the globe.[2] Before the GSM system was implemented, most countries used cellular systems that were often in conflict with each other. Most mobile telephones could only function on their specific cellular network, and as a result many customers could not travel to neighboring countries and still expect service. With various types of systems only serving exclusive groups of people, the large-scale production necessary to manufacture low-cost subscriber equipment was not practical. This resulted in high equipment costs and systems were not very successful in the open market. In 1990, the first phase of GSM specifications was finalized. This included basic voice and data services.[3] Around the same time, the initial efforts were made to modify the GSM specification to offer service at the 1800 MHz frequency range. DCS 1800, which the standard is now known as, is used for the Personal Communications Network (PCN).[4] Since that time, Phase 2 of the GSM and DCS 1800 specifications has been completed. In this phase, enhanced data transfer capabilities and advanced short messages services were added. [5] GSM RADIO â€Å"GSM radio is a wireless communication system that divides geographic areas into small radio areas (cells) that are interconnected with each other.†[6] Each of the coverage areas has one or more transmitters and receivers that converse with cellular handsets in its designated area. GSM radio systems function in a particular frequency band or bands that have been assigned to the system. Depending on the frequency plan, system administrators may choose to recycle specific radio channels at different cell sites. Through a combination of either TDMA or FDMA, subscribers share each radio channel. A GSM radio channel is 200 kHz wide and is further divided into frames that are made up of eight time slots. Each cell site may contain several channels which are shared by as many as 8 to 16 voice users per radio channel. TDMA Time division multiple access (TDMA) is a method of sharing one radio channel through the division of time slots which are then subsequently allocated among multiple users of that radio channel.[7] A mobile radio is assigned a particular time and position on a channel when it communicates with a TDMA system. Through this process, it is possible for a TDMA system to allow multiple users to operate on a single radio channel through the use of separate time slots. TDMA systems therefore amplify their capacity to serve several users with a limited number of radio channels. GSM employs time division multiplexing (TDM) to distribute one modulated carrier frequency radio waveform between 16 half rate or 8 full rate phone calls.[8] Because of this, a clear distinction is often made between a communication channel and a radio carrier in many publications pertaining to GSM. DUPLEX CHANNELS Duplex communication is the transmission of voice and/or data signals that allows simultaneous 2-way communication.[9] In order for duplex communication to occur on analog systems, a separate voice path must be assigned to both a transmitter and frequency. This method of using two frequencies for duplex communication is called frequency division duplex (FDD).[10] Time division duplex (TDD) is another technique that can be used for duplex communication. Time sharing allows two devices to achieve two way communications through TDD. Similar to how a walkie-talkie works; one device transmits while another receives. Once the original transmission is complete, the second device becomes the transmitter while the first becomes the receiver. This process then constantly repeats itself so that the data seems to flow in both directions instantaneously. The GSM system utilizes both FDD and TDD communication. One frequency is used while the handset communicates with the cell tower, while the reverse communication from the tower to the handset uses the other frequency.[11] However, TDD is also used in the GSM system while the transmitter and receiver talk at different times. This time offset between the transmission and reception also helps to streamline the design of the handset. The radio frequency separation between the forward (downlink) and reverse (uplink) frequencies differs between the frequency bands. As a general rule, the separation must be greater between the forward and reverse channels at the higher frequencies. For instance, the frequency separation in the GSM 900MHz system is 45 MHz while the separation is 95 MHz for PCN. Finally, the GSM PCS 1900 MHz system has a frequency separation of 80 MHz.[12] VOICE SERVICES Voice service is a form of communication service in which multiple users can transmit information over the voice frequency band via a communication network.[13] Voice service consists of the initiation of sessions between at least two users which allows for the real time, or near real time, transmission of voice signals between those users. A GSM network delivers numerous types of digital voice services. A number of factors can affect the quality of voice service on a GSM system. However, through the use of several distinct forms of speech compression a GSM system can dynamically adjust the voice quality.[14] Each service provider has the ability to choose and manage which speed compression process (voice coding) their network utilizes. Service providers can increase the amount of users that they provide service to through the use of voice coders that possess higher speech compression rates. However, this comes at the cost of delivering a more degraded signal to each user. Besides ba sic voice services, the GSM system can also provide both group and broadcast voice services. DATA SERVICES A data service is a communication service that transmits information between two or more devices. By means of a communication network, data services can be delivered either inside or outside of the audio frequency band. Data service consists of the creation of physical and logical communication sessions between two or more users. This allows for the non-real time or near-real time transfer of data type signals between users.[15] However, a data modem has to be used in the event that a signal is broadcast on a non-digital channel. The data modem is needed to translate the signal into tones that can be sent in the audio frequency band. GSM voice traffic channels cannot send or receive analog modem data because the speech coder utilized by the system is only capable of compressing voice signals.[16] Medium speed packet data and low-speed circuit switched data are the two services provided in a GSM system. Circuit switched data is a communication process that maintains a committed communications path between two devices.[17] This can be accomplished no matter the amount of data being sent between the devices. This provides sole use of the circuit to the communications equipment employing it regardless of whether or not the circuit is idle. In order to create a circuit-switched data connection, the address must be sent before a connection path is established. Once this occurs, data is continually transmitted usin g this path until it is disconnected by request from either the sender or receiver.[18] Packet switched data service is the other utilized by a GSM system. Through the division of data into small packets, information can be transferred between two points. In order to reconstruct the original data, the packets are routed through the network and recombined at the receiving end. This can be achieved because the destination address is contained within each individual packet. So no matter which route the packets take through the network they will end up at the same destination. The GSM system uses general packet radio service (GPRS) to provide its packet data service. In using the GPRS system, new gateways and packet control channels are added to a GSM system. It is important to note that GPRS is a type of packet-switched data service that is known as â€Å"always-on.† This means that when a device is turned on it acquires an IP address that it needs in order to communicate with the network.[19] CDMA Code Division Multiple Access (CDMA) is a digital cellular radio system currently in use in more than 35 countries around the world.[20] It is a form of spread spectrum communications in which a radio signal is transmitted over a dedicated channel as a much wider signal than is traditionally necessary. By using a signal with a wider than normal bandwidth, interference from other users on the same section of bandwidth is minimized. This permits several users to share the radio channel at the same time. Come in two basic forms: frequency hopping and code division.[21] Frequency hopping multiple access (FHMA) is an access technology in which mobile radios or cellular handsets share radio channels by breaking their transmissions down into short bursts over a number of frequencies. A device transmits for a short period of time on one frequency, and then hops to another radio frequency to continue its transmission. CDMA allows a number of users to share a single radio channel frequency simultaneously by designating a unique code sequence to each mobile radio. By assigning a particular hop pattern to each mobile device collisions can be minimized. Even if collisions do occur randomly only a small amount of data may be lost. Furthermore, error detection and correction methods can be implemented in order to fix the data that was lost.[22] Compared to previous narrowband wireless systems, CDMA technology is a wideband spread spectrum system. It is important to note that the features, services and requirements for CDMA were developed by standards organizations using many pre-existing technologies. For this reason, CDMA is considered a second generation (2G) cellular system. HISTORY OF CDMA The growth of CDMA technology began in the United States in 1989 as a result of the CTIA next cellular generation technology requirements.[23] In September of the previous year the Cellular Telecommunications Industry Association (CTIA) presented the User Performance Requirements (UPR) for the next generation of wireless service. In 1989 the Telecommunications Industry Association (TIA) designated TDMA as the radio interface standard. Later that year QUALCOMM was able to build a CDMA system that met the CTIA requirements. This was achieved largely through the support of mobile telephone manufacturers and carriers, as well as new infrastructure equipment.[24] QUALCOMM and its associates presented the results of their field trials at the end of 1991. This pushed the CTIA Board of Directors to implement a resolution which requested TIA to structurally organize new developments from wideband systems. By mid-1993 TIA had voted on and accepted IS-95 as the CDMA air interface standard radio specifications. The systems which were based on the IS-95 standard became known as cdmaOne systems.[25] In 1995 the first commercial CDMA network was implemented in Hong Kong. CDMA RADIO CDMA is the fasted growing technology in wireless communications. A CDMA network consists of the same basic components as other wireless systems. This includes a mobile station, base station, a controller, and finally a switching network. In CDMA, a carrier frequency is separated into 64 individual channels through the use of codes. Each channel transmits the data associated with a separate and unique conversation in digitally coded form.[26] In some cases an independently coded channel transmits signals related to the start of a connection. In spread spectrum systems like CDMA, one carrier holds multiple channels. This can sometimes lead to confusion when discussing CDMA with someone who is familiar with the older analog frequency division multiplex (FDM) systems. With older FDM systems a channel is synonymous with a carrier. Therefore each pair of carrier frequencies was able to carry only one conversation.[27] All CDMA networks use a specific radio frequency band for signals from the base transmitter to the mobile receiver and a second distinct radio frequency band for the signals from the mobile transmitter to the base receiver.[28] CDMA technology can be used in either the existing 800 MHz cellular frequency band or the 1900 MHz personal communications service (PCS) band. CDMA has the ability to function in the same radio spectrum allocation as older cellular systems when it is being used on those networks. The mobile station transmit frequency band is between 824-849 MHz, while the base station transmit frequency ranges from 869-894 MHz.[29] When in use in the 800 MHz band, CDMA maintains a 45 MHz separation between the forward and reverse channels. Some radio carrier frequencies are defined for CDMA use in its cellular network. However, not all of these frequencies are used for CDMA transmission. This is because the FCC requires that analog radio transmission (AMPS) continue to operate . CDMA operation is also compliant with the frequency structure of the PCS band. The separation of the forward and reverse channels is 80 MHz while operating on this band. The mobile station transmit frequency band is between 1850-1909 MHz; while the base station transmit frequency band ranges from 1930-1989 MHz.[30] Some CDMA systems operate in the Personal Communications System (PCS) frequency bands. PCS is mostly found in North America on the 1900 MHz frequency band, where it is known as PCS-1900. Due to the commonality of the base band signals, some manufacturers make dual band CDMA handsets that are capable of operating on both the 800 MHz and 1900 MHz bands.[31] If a subscriber’s handset is manufactured to allow dual frequency band operation it is possible to obtain service on either or both systems. However, this can only be achieved if the CDMA networks in the region are properly linked. As CDMA moved further towards a third generation technology, the CDMA2000 arose as t he next level of the IS-95 standard. 3G TECHNOLOGIES The term first generation system (1G) is most commonly used in regards to older analog cellular systems. These analog systems eventually gave way to the newer digital second generation systems (2G) that are popular today. 2G systems in use today include the GSM and cdmaOne systems previously mentioned in this paper as well as the US-TDMA and PDC systems.[32] These systems allowed voice communications to go wireless in most of the industrialized world and have drastically increased mobile handset functions. Subscribers have come to expect their cellular networks to provide them with text messaging and data access capabilities. In the United States it is almost unheard of now for a network provider to not offer data services in excess of 500 MB if not at least 1GB per month. The abundance of 2G technologies spurred the demand for even greater services. At the 1992 World Administrative Radio Conference (WARC) of the ITU (International Telecommunications Union), member nation delegates began to investigate the frequencies that would be available for future expansion of 3G systems.[33] The International Mobile Telecommunications System 2000 (IMT-2000) was created as a result of this meeting. It is important to note that IMT-2000 is often used interchangeably with Universal Mobile Telecommunications System (UMTS). UMTS defined a wireless communication system that operates in the 2GHz frequency band.[34] The primary objective of IMT-2000 standard was the development of a single universal air interface that was built upon pre-existing infrastructure. This would help to keep start-up costs low and potentially allow international roaming. The Third Generation Partnership Program (3GPP) was created to coordinate this process. It became evident early on that a single air interface would be nearly impossible to attain so a second committee was formed to oversee the process of bringing other air interfaces up to the IMT-2000 standard. A second partnership program was established to ensure this would occur and the 3GPP2 was born. The two partnership programs are essentially drawn along the fault lines of GSM and CDMA. UMTS, which is often used synonymously with Wideband CDMA or WCDMA, has become the standard for GSM 3G technologies and falls under the umbrella of 3GPP1. The 3GPP2 on the other hand focuses on the CDMA2000 standard.[35] BIBLIOGRAPHY Arokiamary, V. J. (2009). Cellular and Mobile Communications. Pune, India: Technical Publications Pune. Balston.

Essay on "Flight" 	It is always hard to get separated from someone you love and with whom you have shared every moment of his life until he decides to walk on a different path than yours. You don't know how to react and confusion dominates your mind. Should you be angry at him for leaving you, or should you support and respect his decision ? In her essay "Flight," Doris Lessing illustrates the story of an old man who is learning to let go his granddaughter as she grows into an adult and is about to get married. Lessing wisely delivers this particular old man's situation to her readers through her use of literary techniques and devices. Thus, she greatly succeeded at making her readers feel and live the grandfather's difficulty to get separated from his granddaughter. 	Throughout the story, Lessing skillfully uses narration and description to catch the readers attention, making us feel the grandfather's state of emotions. Hence, in the beginning of the story, we first meet his granddaughter Lisa through his eyes that "travelled homewards along the road until his granddaughter swinging on the gate underneath a frangipani tree. Her hair fell down her back in a wave of sunlight ; and her long bare legs repeated the angles of the frangipani stems, bare, shinning brown stems among patterns of pale blossoms." We follow the movement of his eyes that see her as a shinning light that illuminates his life to which he is addicted. Moreove...

My Favorite Movie Essay

My favorite movie is Chinese Super Ninja. The movie has characters who combine fighting with a lot of gymnastics. In the movie the characters demonstrate the precision and skill it takes to use Kung Fu on an opponent. There are many clans in this movie and some have their own fighting style. It is interesting to watch the characters combine fighting with gymnastics. In one scene the fighter did two handsprings and landed in a tree to avoid being hit. Then another fighter tumbled down from the tree striking a fighter with a kick to the chest. see more:favorite movie essay In the movie, characters demonstrate Kung Fu which take a certain skill and precision to work properly. For example, in the movie the fighter must strike the temple to weaken the armor around another fighter in order to kill him. Another example is when the fighters learn to breathe properly so it locks the muscles and the body becomes invincible to blades. If not done properly, the fighter will become vulnerable. The movie also has different clans and fighting styles. There are some small clans such as Lama, Tai Chi, Mings, and Ninja. Another clan is called the Wu Tang Clan and they’re known for using the Lightening Sword Style and the Drunken Monkey. There is also a clan named Shaolin Temple who are known for using the Chinese Finger Jab, Eagle Claw, and the Iron Fist Style. Chinese Super Ninja is my favorite because of the skill of the Martial Arts and knowing the different clans and their fighting styles.

Grill case Essay

In this case, we can appreciate the Sunset Grill at Blue has operational failures on management of capacity and demand which should be considered to solve to get success. Also it explains how the Sunset Grill at Blue was a restaurant which his aimed was to provide affordable meals that appealed to the entire family during their vacations. This restaurant offered breakfast items and lunch menu through the day. The franchisor of this restaurant always was focused on how he could save waiting time to the client when they come to eat in the restaurant instead of customer’s satisfaction. For this reasons, the owner evaluated important points about the service he has on the restaurant. First, he had a strict police of no-substitutions plates even when they brought the wrong plate and he knows that was bringing complains from the customers. In addition, the franchisor thought that maybe he could reduce items from the menu. Also, he realized they have more clients during the weekend and for that reason he decided to hire one runner staff who just delivers the food from the kitchen to the tables, allowing serves to serve customers more efficiently. No concern for the client No waiting area The Sunset Grill was not able to making a special area for the clients give them a place more comfortable at the restaurant if they need to wait. As the case mentioned, the client had to wait around 40 to 50 minutes to get the table and order their food. The lack of this waiting area, was affecting directly to the clients. They could be losing some of them because they can find another place without waiting that time. Also, nobody wants to wait 50 minutes for a table on an uncomfortable place. No customer feedback â€Å"The relationship with the customers is of paramount importance because it is a source of innovation and differentiation† (service management, operations strategy, Information Technology, Fitzsimmons. J, 7th edition ). The franchisor of Sunset Grill shows he didn’t have any relationship with the clients in order to get feedback to improve the restaurant. He focused his business on reduce the time to their clients, instead of worry about client’s satisfaction.

In our society, racial inequality has always been a concerning issue for past decades, but certain parents’ state their opinions on the open discussions of our history and present with racism. The question of whether or not they should speak to their children about the racism that certain individuals receive has caused controversy in our society. There are parents who claim that they have unbiased judgments on the topic while others strongly commit to reminding the children that racism should be an important topic that should be talked over. Parents differ when it comes to the message they project towards children about race, but the message changes with children’s capacity to understand it. So the actual importance is if children should be introduced to the racial madness at such a young age like we have been doing in schools and in society or should the parents stand up and eliminate the racial topic for good. Although with the parents that are not overly racist, there is multiple concerns of whether or not to speak to their children about how their own race discriminates certain people in our society. Furthermore, there are numerous people in our society, especially parents, who believe we should consider not bringing up racism to future generations and instead take the step into a post racial era since we have improved tremendously in race relations. On the contrary, some parents believe the discussion of racism is important for children to be aware of the outcome it has produced and the background of why racism occurs, and in this case, I do strongly agree with the parents. There are a few parents whom have decided not to speak about racism. They believe the media nor did neighbors and friends play a crucial part in their decision making. They consider Reyna 2 themselves unbiased to all the controversy that occurs in their community over the racism topic, especially when it comes from a white individual. Without the society’s ideas swirled up in their mind, the parents are able to describe every perspective that can be observed of the racism. The importance of being able to see every angle of the racism that the minority group receives will help eliminate the bias judgment that we witness in the media or what we are told by others. With this in mind, the decision to consider the topic of racism in family conversations becomes easier to either bring up or shut down. It becomes easier because parents are able to discuss and inform their children that there is more than just one perspective that society defines as racism against the minority ethnicity. White parents can defend themselves from the ignorant comments and stories that people tell about their racial comments towards the African Americans. It is easier to speak about racism than to keep quiet in today’s society, but that seems to be the problem. On the contrary, white parents can also choose not to speak about the racial topic by ignoring it completely. Shutting down the media and any outside influence can assist furtherly with the unbiased decision to choose not to speak to their children about it. In today’s society, it is difficult to say that parents are not influenced in some way in their choices in life. Although parents can shut down the influence from the media, it is impossible to do the same to their children without turning them away from society as well. In all truth, once the child steps out of their home and their parent’s view on society and racism, the child is left vulnerable to society biased judgments on racism and everything else. There are parents who allow the media and any other influential speaker effect their decision on whether they, as not so overly racist yet biased parents, should intensify and enhance to their children about racism in their community and in the society. A majority of the parents are influenced by the media’s portrayal of discrimination on African Americans. Parents who choose to speak about racism to Reyna 3 their children after hearing and witnessing stories and racist acts throughout the country, will either help stop discrimination or unintentionally influence further acts of racism. In reference to the book of â€Å"The Color of the Water†, racial equality was shown to be unbalanced through the society and the effect it had on people since they witnessed it in their own family. In the book, James, one of the Ruth’s 12 kids, had taken it upon himself to write down every single detail that flooded back from his mother’s past. Throughout this James discovered how strong his mother was due to all the things she had to go through and the protection she enhanced for her kids. She protected them because she knew racism would be their biggest trouble and the consequences it would lead to. Society has a lot to do with the influence of racism. Future parents should remind their children of the horror of racism that occurred decades past, or should they just ignore it and try to move past it? In my opinion, speaking about racism seems to be the best way to go. Usually the second most influential people in parents’ decision making are neighbors and friends. They communicate with each other and speak of all their experiences which leads to further leverage on racism itself. Lastly, parents’ own assumption on racial inequality will influence their manner of discussing it to their children. Once parents decide to speak to their children about racism, question rise that become too difficult to answer and the biggest issue is parents’ own prejudice. If the answers aren’t well understood by the children it might lead to trouble and further racism. Sometimes children witness their parent’s unintentional discriminations towards other adults even when it is taught to be moral and caring for others which can also lead to further racism. This is why parents should try to educate their children of racism in order to avoid any misjudgments of their parent’s or anybody else’s actions, and this will help avoid their children’s own unintentional racism towards African Americans. Nelson Mandela inspired people with a few words that would better understand this topic, â€Å"No one is Reyna 4 born hating another person because of the color of their skin. People learn to hate, and if they can learn to hate, then they can learn to love†¦ † In reference to all the parent decision on whether they, as white parents, should talk to their children about racism. In my opinion as well as most people, believe that the more parents talk about the racism the easier it will become to educate future generations of what they should not do in society. Our goal as a society, and the reason behind the social experiment that the United States is experiencing, is to create a post racial era. There is a fear that if people don’t remind their children about racial history then it is likely to cause racial discrimination to occur once again and have history repeat itself. As true as that might be, it is also more likely to be wrong. In many cases, the children might begin to get ideas of past discriminations to inflict on current black children. The stereotype about the minority group will keep at stand which will eventually lead to the continuation of the racism. Therefore, the parents and society as well are pressured to continue speaking to their children about racism in order to help them understand the meaning and the harm it does on the victims. [African Americans] Although the future may not be predicted, parents whom decide not to speak about racism, all because it doesn’t seem important to address it anymore, are probably causing our society more harm than good. Some parents do not intend to speak about the racial discrimination because it draws negative attention to the society, and even if all their reasons seem logical, education has always proved to be far more successful than any other option. The parents who refuse to bring up the topic of racism in their family have very strong views about it that should be considered by others. There was once a research program done in 2011 where a few psychologist wanted to ask questions to white parents about their communication with their children about racism. At first the parents didn’t know what the topic Reyna 5 of the questions would be during the research, but as soon as they were told the topic, many parent withdrew from the experiment due to it discussing racism with their children. The parents strongly believed that there shouldn’t be an open discussion with their offspring about race and the discrimination among the minority group. It came as a shock to the psychologists and scientist over the outcome that was displayed before the research was even done. Without even knowing, the research team developed new results on the topic of race without successfully completing their research on their primary experiment and questionnaire. The simple answer was that the white parents that were supposed to participate didn’t want their children to be aware of the inhumane discrimination over skin complexity. They, also, didn’t want to expose them to the violence that arises from racial discrimination such as the hate crimes, the segregation, and the bullying of children their same age. Although many won’t comprehend the reason behind the racism, discussing it will only seem to promote racism in the eyes of the children even when many parents disagree. The parents should not speak about racism because there is a fear, naivete and denial from the white parent’s own thoughts that if they do speak about it to their children the whole truth can become misinterpreted or in many cases, biased. There is an article by Dr. Harris-Britt that goes over the reasons why white parents should not speak about race. Dr. Harris-Britt speaks about the fear, denial, and naivete that parents encounter as being a negative decision. By them discussing to their children the increasing issue of racial discrimination, the attention that racism is receiving becomes unbearable. The point of view that the article feeds to the reader goes hand in hand with the section of this essay where the racism discussion in families and the white population should avoid each other. Parents may fear their own thoughts and the truth of their judgments towards African Americans. Parents can deny the color discrimination that happens in Reyna 6 their own home, or community. Many will believe that we are already in the post racial era, and will use this belief in order to not openly discuss the subject with their children. Although we do not yet live in a post racial era, we can soon get there if racial discussions can be eliminated. If people would stop dividing them self by race, and focused on their own unintentional discrimination that they might give off, the white race parents won’t find it necessary to warn or inform their children of the racial discrimination that will probably occur to their African American friends, acquaintances, or classmates. In my opinion, these should be used as examples to enhance and persuade other parents that it is far much better to inform all children of racism before they receive or misinterpret other information given to them by someone else, like the media. Some parents will argue that racial ignorance erases the history and experiences that led up to the freedom from racism, hence why those as parents should speak of other race’s experiences and hardships in order to prevent them from happening again. In reference to an article titled 5 Reasons We Need To Talk to Kids about Race in America by Bree Ervin, it states that parents of the white race should consider speaking to their children about race, especially by beginning at the youngest age where they can understand what they’re being told. With all the reasons given, Bree Ervin has sided with the parents who strongly suggest it is the right choice to speak out to our children about racial history and the changes that must be done to prevent history repeating itself. The strong argument is that when we are â€Å"color-blind,† we also tend to discount or dismiss other people’s experiences of race, racism, and bigotry. Parents should not only speak about racism, but should educate their children as well because educating their children about race helps them fight racism and create change. A good example of childhood education about racism would be a TED video of a woman named Chimamanda. Chimamanda Reyna 7 was a Nigerian woman that was well thought and informed at such a young age. In the TED video about Chimamanda Ngozi Adichie, she spoke of a childhood story where her parents educated her about the African Americans racial history and that how their own black race was a part of our country’s history, not just the perspective of the whites that most books mention. They wanted her to have more than one view on what the people of our country have gone through. Although Chimamanda Ngozi Adichie’s parents were not of the white race, it was still necessary for them to teach and have discuss the topic with an open mind. By informing of the past to the next generation, parents will be able to prevent racism of African Americans. It is always a difficult decision on what is right or wrong for a child to know. No matter what decision the parents end up making at the end of the day, every parent thinks they are doing what is best for their child. Some parents are worried that by not informing their children about the active racism that is and has been going on for so long in the United States, the children will only end up falling into the black hole of the negative racism attention that is occurring. Although they may have a point, the rest of the parents aren’t prejudiced nor biased nor are they influenced by any other media source or individual and have concluded that is safer not to mention or allow children to discuss racism among the family or anywhere else because it only feeds on the negative attention that it promotes. It is hard to say which is the right choice that the white parents should make about racism, but they both do indeed have good reasons behind their view on it. We have to be armed with the fact to give our kids what they are owed which is honest conversations about the reality of the world that they are inheriting, but that can only be accomplished by allowing ourselves to acknowledge that racism and issues of race and bias are still present. Just as parents were informed of racism, in my opinion, children should be educated about what is going on in our Reyna 8 country about the racism against the African American race. The best way to solve a problem like this has always been through education. Although many parents believe that the racism will never end because we continue to bring it up, the future generations [the children] will end up never understanding the past racism if it fades away with time. Parents of the white race should consider communicating with their children about racism towards African Americans, but should keep in mind about any social media influence, such as the news, that the children will encounter. The children will hear about racism, but its best that it first comes from the parents in order to prevent any further incidents of it or negative promotion.

Case - Essay Example Any decision in the company affects the decision taken by EPA later, Jonica and other executives, besides the company itself, are stakeholders. A dip in the profitability of the company will affect the perception other stakeholders regarding the management’s ability to make decisions that may lead to profitability, or which may prefer pollution of the lake. Any decision they make will affect the management of the company. There are different moral considerations in the above issue; the first ethical consideration involves an ethical dilemma. Though Jonica and the administration have an obligation to ensure the profitability of the company, it would be ethical to make a decision for the good of the environment, despite the cost to the company. Ethically, it would be preferable for the company to suffer a loss that year, but be recognized for its strong ethical CSR. On the overhand, although EPA has not made a declaration of the steps necessary to reduce the emissions, Jonica and the management have an ethical duty to act for the good of the environment based on the scientific conclusions given. Acting to reduce these emissions based on the scientific study provided even before EPA steps in to intervene will increase the ethical standing of the company among its stakeholder. Therefore, acting on the contrary to attain profitability would be a moral lapse on the part of the management. Foregoing, profit s and implementing the technology to reduce emissions would be a tough tradeoff, which will result in a right-right situation, unlike ignoring the scientific findings, which is a moral lapse. The company would stand to gain from such strong moral values as it would gain favor from customers in the market In resolving the situation, Janica and the management did not have an option, as the technology would be forced through, when EPA backed by the public get the scientific findings. To be the on the safe side, Janica and the

Constitutional Law Master Essay Example | Topics and Well Written Essays - 1000 words

Constitutional Law Master - Essay Example There is no technical difference between ordinary statutes and law considered "constitutional law." Therefore the Parliament of the United Kingdom can perform "constitutional reform" simply by passing Acts of Parliament and thus has the power to change any written or unwritten element of the constitution. The constitution is based on the concept of all sovereignty ultimately belonging to Parliament (Parliamentary sovereignty), so the concept of entrenchment cannot exist. The lack of a central written constitutional document explaining the fundamental principles of the state and relationship between its institutions and between the people leads some constitutionalists to regard the United Kingdom as having "no (formal) constitution." The phrase "unwritten constitution" is sometimes used, despite the fact that the UK constitution incorporates many written sources, statutory law being considered the most important source of the constitution. But the case remains that the constitution re lies far more on unwritten constitutional conventions than virtually every other liberal democratic constitution. Conventions as a source of constitutional rules have been widely acknowledged. Regardless of whether a country possesses an unwritten1 or a written constitution, constitutional conventions usually play an important role in regulating constitutional relationships among different branches of government. A common definition of constitutional conventions is: "By convention is meant a binding rule, a rule of behaviour accepted as obligatory by those concerned in the working of the constitution."2 Law and constitutional conventions are closely related. Constitutional conventions presuppose the existence of a legal framework, and do not exist in a legal vacuum. For example, in the UK, the constitutional conventions of forming a Cabinet presuppose the laws relating to the Queen's royal prerogative, the office and powers of Ministers, and the composition of Parliament.3 A difference between law and constitutional conventions is that laws are enforceable by the courts, but constitutional conv entions are not enforced by the courts. If there is a conflict between constitutional conventions and law, the courts must enforce the law. In some countries, such as the United Kingdom (UK) and Canada, the courts acknowledge the existence of constitutional conventions as aids to judicial interpretation.4 Academics consider that such acknowledgement may at 1times appear to be similar to enforcement.5 The constitution ... is seen to consist of two different parts; the one is made up of understandings, customs, or conventions which, not being enforced by the courts, are in no true sense of the word laws; the other part is made up of rules which are enforced by the courts, and which, whether personified in statutes or not, are laws in the strictest sense of the term, and make up the true law of the constitution. This law of the constitution is, as we have further found, in spite of all appearances to the contrary, the true foundation on which English polity rests, and it gives in truth even to the conventional element of the constitutional law such force as it really possesses. First, as constitutional conventions can easily be adapted to new circumstances arising, they are therefore frequently used as a means of bringing about constitutional development, provided that those constitutional co

Dental education in United States especially University of minnesota Research Paper

Dental education in United States especially University of minnesota - Research Paper Example According to this work, Hayden was born in a military family with most of the members of his family serving as honorable military personnel. In fact, it is documented that one of his ancestors served as a captain in the Pequot war for a whole lifetime. Haydens first career was architecture but after taking a vacation in New York and visiting Dr. Greenwood, he changed his vocation to dentistry. He then moved back to Baltimore and established a dental office or clinic treating patients with dental problems within his reach. At the start, dentistry was majorly learnt through the mediocre preceptorial system that made it look like a mechanical process instead of the science that it was. Despite the existence of a national dentistry union in the United States, many of the practitioners were not treated as members of an organized profession. In fact from the start, the members of the profession were subjected to a treatment that focused on the viability of the profession. As a result, the training on the profession experienced a number of challenges that were based on the admission of the profession to the field of medicine. In this paper, while examining the history of dentistry education in the United States, also explores the fact that the establishment of dental education was marred with an infinitive link between the subject and medical education. As such the difference caused a rift that would shape the acceptance of the practice and education of the same. Thesis: the establishment of various state legislations and provisions within law led to the recognition of dentistry in the education system and medical fraternity. The introduction of dental studies and its origins in Maryland and the influence of the British nationals, therefore, has a special relation. The British threat of Baltimore in 1813 made Hayden enlist as a private in the army commanded by Captain Christian Anderson within the Maryland
