Memo - Essay Example It is during this time that the company was confirmed to have increased its earnings in a profit margin of 50% as compared to 25% in the previous years. As a result, the CEO rewarded me for the contribution I had made for the two years through my hard work and diligence while working with the company, affirming that the company had a tremendous increase in profit during my tenure. Needless to say, this is one of the achievements I am still proud of to date. Moreover, before I came to the U.S from Saudi Arabia I used work with one of the biggest Oil Companies (Saudi Aramco) in the country. My job description was a manager, with the responsibility of overseeing 65 employees out of the total 300 working under my supervision. Consequently, I would like to retaliate that the responsibility of supervising 65 employees particularly in the production department of an Oil company is not easy but requires patience, understanding and motivation of the employees in order to increase productivity and maximize on profit. Finally, I have engaged myself in a number of community services in the last few years since I completed grade school. To begin with, I am a member of ‘Keep it Clean’ initiative which has over a hundred volunteering members who clean recreation parks and public amenities around busy cities in San Diego three or four times a week depending on the weather. Secondly, I belong to a very young youth initiative known as ‘Clear the road and save time’ that began three months ago with the aim of assisting the few traffic personnel present on the roads in easing traffic jams on major roads in Washington D.C. Since it is volunteer work, I ensure that I dedicate two hours of my day to the initiative. Similarly, I have strictly dedicated my free time to assisting lost people and locating their intended destinations. This idea came up after I realized that

Public transport Essay Example for Free

Public transport Essay Public transport can be described as a shared service of passenger transportation readily available for public use. Modes of public transport in many modern cities include trains and trams, buses, trolley buses, ferries and rapid transit. Public transport is necessary to economic and social development, with easy movement of people, goods and services. Increased number of motor vehicles in the modern cities carries both economic and social costs evidenced by increased air pollution. Air of poor quality can serious affect the health of the public and can result to premature deaths. Public transport is said to be the key of reducing air pollution in the urban cities in the following ways: reduced emission of carbon monoxide, reduced emission of nitrogen oxide and carbon dioxide emission, reduced emission of the volatile organic compounds and minimized fossil fuel consumption. Studies have shown that private vehicles, which are mainly petrol-powered, emit carbon monoxide, lead, benzene and lead which are detrimental to the air in our cities (European Environment Agency 2010). Still, due to the large number of this private vehicles, they are bound to emit this pollutants in high amounts compared to public transport. It is clear that, in order to reduce the air pollution and especially the concentration of carbon monoxide in our cities, there is need for people to rely much on public transport rather than the private vehicles. Nitrogen oxide and carbon dioxide emitted on the environment. Study conducted by the American enterprise institute and Brookings institution in 2002 showed out that the quantity of nitrogen oxide and carbon dioxide emitted by the private vehicles was about double the amount emitted by the public transport for every mile traveled by a passenger (European Environment Agency 2010). Use of public transport can reduce carbon footprint of an individual. Another study in the year 2005 showed that the use of public means rather than the private means could have reduced the carbon dioxide emission in the United States by 3. 9 million of metric tones. So it is much possible that, reducing air pollution in our cities can be achieved by depending more on the public transport. On other organic volatile compounds, the same study showed that the private vehicles could emit 92 percent more organic volatile compounds than the public vehicles as compared to mile traveled by each passenger. Efforts of reducing air pollution in our cities should focus on how to minimize usage of private vehicles in transport and also encourage use of the public means in transport. The same studies by the same two institutes showed out that in United States, public transport only used half of the fuel which was required to fuel the private vehicles. The more fossil fuel is used, the more emission of pollutant air is likely to emit in the environment, so in order to reduce the air pollution in our cities, there is need to encourage use of public transport. Public transport is very vital in our cities especially in achieving the global war on reducing air pollution which can result to global warming. Efforts need to be put in place to ensure that people use much the public means in most of their traveling because it will reduce air pollution in our cities as well as reducing the urban congestion of vehicles and also reduce the overdependence of energy imports.

L.A. Gang Member by Sanyika Shakur Essay -- Monster Autobiography L.A.

L.A. Gang Member by Sanyika Shakur Kody Scott grew up in South Central L.A. during the nineteen-sixties and seventies, soon after the creation of the Crips. Raised in poverty without a father, and a full family raised solely by his mother, Kody Scott led the stereotypical â€Å"ghetto† life, a poor and broken home. However he does not blame this on his own personal decision to join the Crips while only eleven year’s old. The allure of the respect and â€Å"glory† that â€Å"bangers† got, along with the unity of the â€Å"set†(name for the specific gang) is what drew him into the gang. Once joined, he vowed to stay in the â€Å"set† for life, and claimed that banging was his life. After many years of still believing this, he eventually realized that the thug life was no longer for him, and that gangs were a problem on society and the â€Å"Afrikan† race(page 382-383). In his book â€Å"Monster: The Autobiography of an L.A. Gang Member†, he tells of his life story and how he came and left the gang life. For thirteen years he was a member of the Eight Tray Gangsters, a set of the Crips, and throughout the book he explains, sometimes in full detail, the life he led while in the gang and his many times in jail and prison. These life stories he tells, include drive-byes, shootouts in supermarkets, parks, streets, houses etc., fist fights, group beatings, kidnapings, doing drugs, selling drugs, car-jacks, amputation, robbery, friend’s deaths, enemies’ deaths, being shot, knife fights, police abuse, jail riots, jail rapes and any other part of the gang life possible. Now if possible, imagine that this all happened within thirteen years, and to a teenager. These crimes, more specifically the brutal ones, are what got him his nickname â€Å"Monster Kody†. None of this really affected him though, until when in jail, he was c onverted to a Muslim, when he changed his name to Sanyika Shakur. However, it took him a while to realize that what he was doing was wrong and it was not what he wanted to do for the rest of his life. Although he now realized this, it wasn’t because of religion really, but more for the survival and advancement of the â€Å"Afrikan† race, as he was now becoming more and more politically and morally conscious(page 277). After coming and going out of prison, he was struggling between the two lives he was trying to lead, one as a banger and the other as a leader for the â€Å"Afrikan†... ...left the gang life behind in order to raise his family in a safer environment and also to settle his conscience down and feel better about himself. In conclusion, Kody Scott a.k.a. Sanyika Shakur, used this book as a tool to help let society know the dangers of the gang life, and possibly some advice to help prevent gangs from growing and spreading, and also to prevent his past from becoming somebodies future. Which is best summed up in his last paragraph from the book in which he states: â€Å"How do we come to grips with the fact that this thing has gotten way too real, out of control like some huge snowball running down a hill, threatening to smash and kill all in it’s path, including those who originally fashioned it? Time is of the essence, and every thinking person with a stake in life-especially those involved in the fighting-should put forth an effort, something more concrete than a â€Å"media truce,† to deal with this tragedy. The children deserve to have a descent childhood where they live. They shouldn’t have to be uprooted to the suburbs to experience peace. We cannot contaminate them with our feuds of madness, which are predicated on factors over which we have no control.†

Oral Diseases During Pregnancy Health And Social Care Essay

Pregnancy is a delicate status affecting complex physical and physiological alterations. Pregnancy constitutes a particular physiological province characterized by a series of impermanent adaptative alterations in organic structure construction, as the consequence of an increased production of estrogens, Lipo-Lutin, gonadotrophins, and relaxin, among other endocrines. The unwritten pit is besides affected by such endocrinal actions, and may show both transient and irreversible alterations every bit good as alterations that are considered pathological [ 1 ] . Pregnant adult females are peculiarly susceptible to gingival and periodontic disease. In this context, different unwritten lesions are reported to be common during gestation. In consequence, an increased prevalence of dental changes excessively has been documented, including peculiarly cavities and erodings [ 2 ] . The biochemical and hormonal alterations of gestation enhance the hazard. Since the old married womans ‘ narrative of â€Å" the loss of a tooth for every gestation, † unwritten wellness during gestation has long been a focal point of involvement [ 3 ] . Vergnes and Sixou [ 4 ] , in their systematic, a meta-analytic reappraisal of 17 articles concluded that there was a statistically important association between periodontal disease and inauspicious gestation results. Perinatal mortality rates in Pakistan and many other developing states are more than 10-fold greater than in developed states. In a survey on periodontic disease and inauspicious birth results in pregnant Pakistani adult females, it was found that they have high degrees of moderate-to-severe dental disease. It was concluded that spontaneous abortion and neonatal and perinatal deceases increased with the badness of periodontic disease [ 5 ] . Patients, doctors, and tooth doctors are cautious, frequently avoiding intervention of unwritten wellness issues during gestation. This job is compounded by a deficiency of clinical guidelines for the direction of common unwritten conditions in gestation. In the absence of pattern guidelines, fright of medico legal action based on negligent or deficient intervention of unwritten conditions during gestation abounds, but it is mostly baseless [ 6 ] . In add-on to a deficiency of pattern criterions, barriers to dental attention during gestation include unequal dental insurance, relentless myths about the effects of gestation on dental wellness, and concerns for fetal safety during dental intervention [ 7 ] . Common PROBLEMS DURING PREGNANCY Oral lesions: During gestation, the unwritten pit is exposed more frequently to gastric acid that can gnaw dental enamel. Morning illness is a common cause early in gestation ; subsequently, a slack esophageal sphincter and upward force per unit area from the big womb can do or worsen acerb reflux. Patients with terrible purging can hold enamel erodings. Rinsing the oral cavity with a teaspoon of baking sodium carbonate in a cup of H2O or using tooth mousse ( casein phosphopeptide formless Ca phosphate ) on the dentition after purging can neutralize acid. Pregnant adult females should be advised to avoid brushing their dentitions instantly after purging and to utilize a toothbrush with soft bristles when they do brush to cut down the hazard of enamel harm. Fluoride gargle can protect eroded or sensitive dentitions. Dental Cavities: An increased prevalence of dental changes has been documented, including peculiarly cavities ( 99.38 % ) [ 2 ] . Pregnant adult females are at higher hazard of tooth decay for several grounds ; including increased sourness in the unwritten pit, sugary dietetic cravings, and limited attending to unwritten wellness. Untreated dental cavities can take to unwritten abscess and facial cellulitis. Pregnant patients should diminish their hazard of cavities by brushing twice daily with fluoride toothpaste and restricting sugary nutrients. Patients with untreated cavities and associated complications should be referred to a tooth doctor for unequivocal intervention. If the female parent ( infecting individual ) has high salivary mutans streptococci count, transmittal occurs through several day-to-day spit contacts between the kid and the female parent. The acquisition of mutans streptococci is suggested to happen during a distinct age interval: a â€Å" window of infectivity † between 19 and 31 months in which the proportion of kids with MS additions from 25 % to 75 % [ 8 ] . Numerous literatures have stated that both hapless nutrition and low birth weight are risk factors for the development of early childhood cavities ( ECC ) . ECC is an early arising, potentially lay waste toing and deadly signifier of dental cavities. It non merely does dentitions, but consequences in hurting, infection and damage of unwritten map which leads to malnutrition and lessened quality of life. Under- or malnourished babies and babies with low birth weight are at hazard for enamel hypoplasia ( uncomplete formation of enamel ) [ 9 ] . Enamel hypoplasia may do an irregular enamel surface or stain, which can ensue in countries more prone to cavities. Therefore, pregnant female parents should be advised to optimise nutrition during the 3rd trimester and the baby ‘s first twelvemonth, when the enamel is undergoing ripening. Pregnancy Oral Tumor: Pyogenic granuloma ( or pregnancy tumour ) seems to be common in the conceiving female population. Pregnancy unwritten tumours are vascular lesions caused by increased Lipo-Lutin in combination with local thorns and bacteriums. Lesions are typically erythematous, smooth, and lobulated ; they are located chiefly on the gum. The lingua, roof of the mouth, or buccal mucous membrane may besides be involved. Pregnancy tumours are most common after the first trimester, turn quickly, and typically recede after bringing. Management is normally experimental unless the tumours bleed, interfere with chew, or do non decide after bringing. Lesions surgically removed during gestation are likely to repeat [ 10 ] . Loose ( Mobile ) Teeth: Dentitions can loosen during gestation, even in the absence of gum disease, because of increased degrees of Lipo-Lutin and estrogen impacting the periodontium ( i.e. , the ligaments and bone that support the dentition ) [ 1 ] . For unsophisticated loose dentitions non associated with periodontic disease, doctors should reassure patients that the status is impermanent, and entirely it will non do tooth loss [ 11 ] . Gingivitis: Gingivitis is the most common unwritten disease in gestation in such state of affairss. It is redness of the superficial gum tissue. During gestation, gingivitis is aggravated by fluctuations in estrogen and Lipo-Lutin degrees in combination with alterations in unwritten vegetations and a reduced immune response, therefore cut downing the organic structure ‘s ability to mend and keep gingival tissue [ 12 ] . Thorough unwritten hygiene steps, including tooth brushing and flossing, are recommended. Patients with terrible gingivitis may necessitate professional cleansing and demand to utilize mouth rinses such as chlorhexidine. Periodontal disease: Periodontal disease is a destructive redness of the periodontium impacting many adult females of childbearing age. The procedure involves bacterial infiltration of the periodontium. Toxins produced by the bacteriums stimulate a chronic inflammatory response, and the periodontium is broken down and destroyed, making pockets that become septic. Finally, the dentition loosen. This procedure can bring on perennial bacteraemia, which indirectly triggers the hepatic ague stage response, ensuing in production of cytokines, prostaglandins ( i.e. , PGE2 ) , and interleukins ( i.e. , IL-6, IL-8 ) , all of which can impact gestation [ 13 ] . Elevated degrees of these inflammatory markers have been found in the amnionic fluid of adult females with periodontal disease and preterm birth compared with healthy control patients [ 14 ] . In one survey, research workers found minimum unwritten bacteriums in the amnionic fluid and placenta of adult females with preterm labor and periodontal disease [ 15 ] . It seems likely that this inflammatory cascade entirely prematurely initiates labors due to early uterine contractions. The mechanism is thought to be similar for low birth weight ; the release of PGE2 restricts placental blood flow and causes placental mortification and attendant intrauterine growing limitation [ 16 ] . PRENATAL Guidance Prenatal unwritten wellness reding for parents is an of import factor because infant unwritten wellness begins at this phase. The chief aim is to bring forth consciousness among parents about dental disease, its bar and the agencies to supply a suited environment for the kid to develop. Prospective parents need to cognize that antenatal appraisal and instruction are indispensable to the unwritten wellness of their kid. Prenatal appraisal includes unwritten wellness position of the parent. If the parents are at hazard, the tooth doctor should supply preventative intervention and educate them on good plaque control, followed by Restorations if required and discourse the transmissibility of Mutans streptococci from the female parent to the baby. Parents should be monitored on a regular footing to guarantee effectual unwritten hygiene and dietetic wonts have been established. Improvement of the female parent ‘s unwritten hygiene, diet and the usage of oral cavity rinses can hold a important impact on the kid ‘s cavities rate in the hereafter [ 17 ] . Anticipatory counsel: Anticipatory counsel is the procedure of supplying practical, developmentally appropriate information about kids ‘s wellness to fix parents for the important physical, emotional and psychological mileposts. Anticipatory counsel involves three types of undertakings: ( I ) assemblage information, ( two ) set uping a curative confederation, and ( three ) supplying instruction and counsel. General prevenient counsel for the female parent includes the undermentioned [ 18 ] , [ 19 ] : ( a ) Education refering development and bar of dental disease and besides presentation of unwritten hygiene processs. ( B ) Reding to instil preventative attitudes and motive. ( degree Celsius ) Supplying information to pregnant adult females about gestation gingivitis ( redness of the gum caused by an exacerbated response to dental plaque, related to hormonal alterations during gestation ) . With gingivitis, the gums become inflamed, conceited, sensitive and tend to shed blood. Signs of gingivitis may go apparent in the 2nd trimester and extremum during the 9th month of gestation. ( vitamin D ) Visiting a tooth doctor for an scrutiny and Restoration of all active decay every bit shortly as executable and to diminish opportunities of developing gestation gingivitis. ( vitamin E ) Eating healthy nutrients such as fruits, veggies, grain merchandises ( particularly whole grain ) , and dairy merchandises ( milk, cheese ) during repasts and bites. Limit eating between repasts. ( degree Fahrenheit ) Eating nutrients incorporating merely sugar at mealtimes, and restricting the sum. Frequent ingestion of nutrients high in sugar additions the hazard for tooth decay. In add-on, frequent ingestion of nutrients that easy adhere to the tooth surface, such as dried fruit and confect, increase the hazard for tooth decay. ( g ) Brushing teeth exhaustively twice a twenty-four hours ( after breakfast and before bed ) with fluoridated toothpaste and flossing day-to-day. ( H ) Rinsing every dark with an alcohol-free, nonprescription fluoridated mouth rinse. ( I ) Not smoking coffin nails or masticating baccy. DENTAL PROCEDURES DURING PREGNANCY Every pregnant adult female should be assessed for dental hygiene wonts, unwritten jobs ( e.g. , cavities, gingivitis ) , and entree to dental attention [ 11 ] . Conversely, inauspicious gestation outcomes, such as low birth weight, preterm birth, and pre-eclampsia, occur in adult females who have non received intervention. Good unwritten wellness during gestation is of import to the overall wellness of both anticipant female parents and their babes. Relevant information sing the type of dental intervention that can be undertaken may be summarized as follows [ 18 ] , [ 19 ] : First trimester: It is the most important period for growing of fetus. Merely exigency dental intervention should be undertaken in audience with the patient ‘s doctor when organogenesis is uncomplete. Second and 3rd trimester: Emergency every bit good as elected dental intervention can be provided. The 3rd trimester presents the extra jobs of positional uncomfortableness and the hazard of vein caval compaction. Prop uping a adult female on her left side, shifting frequently, and maintaining visits brief can cut down jobs [ 20 ] . Postponing dental attention until after bringing can be debatable because new female parents are focused on the attention of their neonates and may hold alveolar consonant insurance merely during gestation [ 13 ] . Plaque diet control plans are initiated for female parent throughout gestation. Screening and Prevention: Oral scrutiny should include the dentitions, gums, lingua, roof of the mouth, and mucous membrane. Patients should be counselled to execute everyday brushing and flossing, to avoid inordinate sums of sugary bites and drinks, and to confer with a tooth doctor. Status of and programs for unwritten wellness should be documented. Many tooth doctors are reported to be loath to handle pregnant adult females [ 21 ] . Physicians and tooth doctors can get the better of this state of affairs through instruction, clear communicating, and the development of ongoing collaborative relationships. Doctors can portion information on the safety of dental intervention in gestation with dental co-workers and supply clear referral recommendations. Diagnosis: Dental skiagraphy may be performed in gestation for acute diagnostic intents [ 22 ] . When possible, skiagraphy should be delayed until after the first trimester. Screening skiagraphy should be deferred until after bringing. Modern fast movie, turning away of retakes, and usage of lead aprons and thyroid shields all bound hazard. The teratogenic hazard of radiation exposure from unwritten movies is 1,000 times less than the natural hazard of self-generated abortion or deformity [ 21 ] . Medicines for Dental processs: Local anaesthetics such as Lidocaine ( Xylocaine ) and prilocaine ( Citanest ) mixed with adrenaline are safe for processs when dosed suitably [ 23 ] . Sedatives such as benzodiazepines ( e.g. , Versed ) , lorazepam ( Ativan ) and triazolam ( Halcion ) should be avoided. Azotic oxide is non rated and its usage in gestation is controversial [ 24 ] . Periodontic Therapy: A randomized controlled test of 870 adult females with pregnancy-associated gingivitis found that intervention ( ie, plaque control, grading, and daily rinsing with 0.12 % chlorhexidine ) and care ( ie, unwritten hygiene direction and manual supragingival plaque remotion every 2 to 3 hebdomads until bringing ) significantly reduced the preterm birth or LBW rate [ 25 ] . Renewing Dentistry: Amalgam, a mixture of 50 % metallic quicksilver and other metals, has advantages over other renewing stuffs ; nevertheless, there is concern that quicksilver can be released as vapor, ions, or all right atoms, which can be inhaled or ingested. Surveies and instance studies of amalgam exposure during gestation have non documented any toxicity, including birth defects, neurologic sequelae, self-generated abortions, or decrease in birthrate [ 26 ] . A longitudinal rating of renewing stuffs employed in a minimum renewing intercession attack of 81 high caries-active pregnant adult females demonstrated that extremely syrupy glass ionomer cement applied in a minimum intercession attack provided high-quality preventative and renewing attention. The complex was employed in pits exposed to lower emphasis, such as in the anterior dentitions [ 27 ] . Dental Extraction: Tooth extraction during gestation seems to be a common thing. The many hormonal alterations during gestation cause many pregnant adult females to hold jobs that they did n't hold before they became pregnant. One of the things that happen is that the gum is much more sensitive to annoyance. They swell, become inflamed, turn ruddy, bleed and are frequently painful. These reactions are to the plaque environing the dentition. It is really common to hold gum job around a wisdom tooth and the surrounding gums merely acquire more aggravated while a adult female is pregnant. This is the primary ground that tooth extraction during gestation is non an uncommon experience.A Of class, tooth doctors would prefer to avoid tooth extraction during gestation. However, the best involvements of the kid must be thought of excessively. A female parent that is in changeless hurting while transporting a kid is emphasizing out her organic structure. This is likely non healthy for the kid. A tooth extraction process nowadays is really soft and many patients are non even aware that their tooth has been removed. Root Canal Treatment: Many pregnant adult females are concerned about the effects of a root canal process to their fetus. Obstetricians suggest that it is best to avoid exposing the developing babe to any hazards, even if they are minimum. Unfortunately, it is non the same to prorogue a root canal intervention as it is to prorogue a dentition whitening process. If the tooth doctor recommends a root canal during gestation, the hazards are associated with: Pain: Dentition that need root canal therapy are normally accompanied by terrible odontalgia. Continuous hurting during gestation can be a truly nerve-racking status with potentially negative effects to the female parent and fetus. Infection: The conditions when a root canal is recommended during gestation ever affect tooth infection. If the infection is left untreated for a long clip, the infection can distribute throughout the organic structure doing terrible complications. This is a status that will set a gestation into important danger. A safer attack to a root canal intervention during gestation: Obstetricians consider the first trimester as the most important for the development of the fetus. Any non-emergency dental work in the 1st trimester should be postponed until the 2nd trimester, to avoid all possible hazards. If needed the tooth doctor can open an abscessed tooth to let drainage and hurting alleviation, and clean the mush country every bit good as possible. Subsequently, when gestation enters the 2nd trimester, an X ray can be taken to let the completion of the root canal intervention. The same process can be followed for a job during the 3rd trimester ; concluding intervention is postponed until after the birth, if possible. Management of Acute Dental conditions: If mild cellulitis is present, penicillin, Amoxil, and Keflex are sensible first-line antibiotics. Erythromycin base ( non erythromycin estolate, which is associated with cholestatic hepatitis in gestation ) or clindamycin ( Cleocin ) can be used in the type 1 hypersensitivity penicillin-allergic patient. For terrible cellulitis, the patient should be hospitalized and treated with endovenous Mefoxins or clindamycin. To pull off dental hurting, Datril is the drug of pick ; isobutylphenyl propionic acid and limited usage of oxycodone are appropriate [ 11 ] . PREVENTIVE METHODS Although a figure of non-invasive preventative intercessions, traditional wellness instruction remains the gilded criterion for presenting the message to promote parents to subscribe to these preventative intercessions. By â€Å" traditional wellness instruction, † which means advice-giving Sessionss conducted by professionals and/or the airing of information via booklets, postings and media runs. Unfortunately, such attacks are non effectual [ 28 ] . Weinstein & A ; co workers, after biennial consequences of controlled test suggested that motivational interviewing ( MI ) guidance has a positive consequence on kids ‘s dental wellness that is greater than that of traditional wellness instruction [ 29 ] . The antimicrobic intervention ( topical application of Na fluoride ( NaF ) and iodine solution instantly after prophylaxis and 3 and 5 yearss subsequently ) for the pregnant female parent, 6 and 12 months after bringing had greater influence by cut downing the acquisition of MS from the female parent to the kids [ 30 ] . Kohler et Al ( 1994 ) used chlorhexidine ( CHX ) in female parents with a high degree of MS in spit and found that there is a decrease in the MS degree of spit of the female parent and besides had a long-run consequence on the MS colonisation and besides on the cavities experience of the kid [ 31 ] . A 30 month survey to measure the effectivity of a cavities preventative government ( 0.05 % Na fluoride and 0.12 % chlorhexidine oral cavity rinse everyday during 6 months of gestation till 24 months after bringing ) showed promising consequences on utilizing combination of fluoride and chlorhexidine [ 32 ] , [ 33 ] . Fluoride is the most widely known and accepted anti-caries agent available, and chlorhexidine is the most widely used plaque-inhibitory compound33. These agents have wholly different mechanisms of action, and their combined disposal produces a synergic consequence on mutans streptococci [ 33 ] . Xylitol and chlorhexidine lower maternal unwritten bacterial burden and cut down transmittal of bacteriums to babies when used tardily in gestation and/or in the postpartum period. Both topical agents are safe in gestation and during suckling [ 34 ] . Surveies have used different dosing degrees, and the optimum dosage for consistent bar is ill-defined. Long-run usage of high-dose xylitol mastication gums had good effects on plaque pH, and that this consequence was statistically greater when utilizing xylitol masticating gums, both on plaque pH and MS salivary concentration [ 35 ] . Decision Dental intervention is indispensable for optimum unwritten wellness, which extends to pregnancy. Routine dental visits can include the usage of X raies, unwritten prophylaxis, Restorations, interventional interventions like root canal interventions, periodontic surgeries and extractions because utilizing local anesthetics during gestation have non been found to be associated with an increased hazard to the developing fetus. Conversely, inauspicious gestation outcomes, such as low birth weight, preterm birth, and pre-eclampsia, occur in adult females who have non received intervention. However, gestation is a clip when adult females may be more motivated to do healthy alterations. Gynecologists and doctors can turn to maternal unwritten issues, potentially cut downing the hazard of preterm birth and childhood cavities through unwritten disease bar, diagnosing, early direction, and dental referral.

Business: Public Relations and Press Release

The website is http://www.jpmorganchase.com/corporate/About-JPMC/about-us.htm. The sender is JPMorgan Chase’s public relations and communications department. Looking at the variety and richness of messages heralding the successes and profitability of the bank, it is obvious that the message is intended for a variety of stakeholders like investors, potential investors, shareholders, customers and potential customers, employees and even its competitors. Analyze the integrated business communication.Integrated business communication is defined as â€Å"†¦the process of planning, executing and evaluating unified messages that create stakeholder relationships and build brand recognition.† (Stuart, Sarow, and Stuart, 2007,p.14) The press release section uses information from public relations, management, organizational changes, marketing and incorporate these into a series of dynamic message that paints a picture of the company as a whole making it possible for stake hol ders to form a comprehensively positive image of the company. For example, if one looks at the press release of April 25th of 2013, one realizes it heralds through its title â€Å"Chase Ranks #1 in Mobile Banking Functionality† a technological milestone that not only places the company ahead of its competitors, but also entices prospective customers who might see this as a plus.In this particular press release,  many stakeholders are targeted at the same time. In another press release dated April 17th 2013 titled â€Å"100.000 Jobs mission Announces 64,628 U. S Veterans hired Through First Quarter2013†, the company uses public relations technique to announce its position as an outstanding responsible corporate citizen through offering employment to a target under-privileged group. This particular release serves also as a public relationship announcement to prospective veterans that employment is done on the spot. This is an image building and publicity stunt that als o targets a wide variety of stakeholders. Assess the media richness of the section.To achieve its communication strategy, the company uses both audio and video presentations, emails, news feeds, downloadable data and links to other pertinent information that may be important sources of enrichment to its readers or stakeholders. Of particular interest is its use of webcasts and live feeds or reproduced information that can be viewed live or at the stakeholders’ convenience by way of archived presentations. Describe how the message is framed.Framing according to Robert Entman is â€Å"selecting, and highlighting some facets of events or issues, and making connections among them so as to promote a particular interpretation, evaluation and /or solution†, (Stuart, Sarow, and Stuart, 2007,p.18). This is exemplified in the very setup of the website and the various breakdown of the message into sections, topics, dates in a coherent and easily accessible way through internet ac cess and other communication tools. For example, the topics are arranged beginning with investor relations, financial information, CIO reports, annual report and proxy, shareholder presentations, corporate responsibility to feedback link in frequently asked questions. A cursory look at the table of contents shows that there is a deliberate attempt at presenting a unified message about the company to its stakeholders that paints a bright light, vision and growth with special attention to the shareholders.Identify opinion leaders.Opinion leaders that are targeted by the communication are shareholders, prospective employees, employees, customers, prospective customers, government regulators, generally known as stakeholders. Make recommendations  for improving word choice.The choice of words while technically appropriate to its audience, may be confusing to the rank and file customer and investor who may not understand the use of technical words. This is seen in the earnings reports, and other communiquà ©s in the website. I would also recommend that concrete words be used to avoid ambiguity. A more simple but concise language devoid of ambiguity, double meaning laden with cramped up facts and data is recommended considering the targeted audience and general public to whom the message is addressed.

Mobile Communication Satellite Systems The WritePass Journal

Mobile Communication Satellite Systems Introduction Mobile Communication Satellite Systems IntroductionReferences:Related Introduction In this era of 21st century one cannot imagine human life without mobile communication. From mobile handsets to computers, smart-phones to laptops, iPads and Cable Television systems everything is part of this mobile communication era. As the countries are progressing, competition among them is increasing all over the world. With the advancement in technology lives of people are getting faster and busier, businesses and industries are expanding globally, therefore, the demand for mobile communication is increasing immensely with every passing day. Scientists, researchers and engineers are always looking for ways to serve the world with this demanding technology in every possible way. During the last 25 years there has been a tremendous growth in the field of satellite communication. The idea of using the Satellite Systems for mobile communication has appealed to many people in the past and it still continue to do so. There has been an extensive research going on in this particular area globally. A lot of progress has been achieved so far but it is a fact that advancement in technology can probably never end. As the demand for communication is increasing, means and resources to carry out this communication are often limited. For instance if communication of information is to take place between the countries that are hundreds of miles apart, across the ocean, the typical wired medium cannot always be used. And also how are we supposed to communicate when we are not connected to the land communication systems by any means? Here satellite systems come into play. With the help of satellite systems we can provide mobile communication services even to very fast moving vehicles, to the aircrafts during flights, to ships and submarines in oceans, and also to remote areas of earth where there is no communication infrastructure. So in this way we are able to provide services to the areas where application of wired cable medium is not always practically possible. Satellites are the object that revolves around the earth in fixed orbits. These satellites are at typically 400 km to 36000 km above the earth surface. Our purpose of communication over long distances is served by these satellites. Another advantage of using the satellite systems for communication is that they can cover a very large geographical area over the earth surface to provide communication means. When we are using a satellite system we are not limited by the problem factors that we encounter on earth such as laying hundreds of miles of expensive cables, space and land to store machinery and equipment to handle this sort of communication, buildings to handle all the infrastructure needed etc. Therefore, Satellite Systems are often given a thought as a better alternative for mobile communication. Before we look into the details of how mobile communication takes place through these satellites, we need to first understand the satellite systems in general as well to have a better understanding of how the whole technology works. Satellites are sent into space from earth. When in space above the earth surface, these satellites are made to revolve around the earth in fixed orbits with the help of gravitational force of the earth. To understand the phenomenon we can take a very simple and well known example from nature and that is of the Moon. Moon is the natural satellite and as it revolves around the earth, it shines over a huge geographical region of the earth. In a similar fashion, man made artificial satellites, though not as big as the moon but still, covers a considerably large section of the earth to provide communication. These artificial telecommunication satellites can be in four different kinds of orbits above the earth surface depending on the purpose they were sent into space. These can either be geo-stationary orbits, elliptical orbits, medium earth orbit or low earth orbits. In geo-stationary orbits, as shown in Figure 1, the satellite remains at a fixed location over the earth surface which means it covers the same geographical region of the earth.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Figure1: Geo-Stationary Orbit Elliptical orbits are used when satellites are required to cover a certain geographical area of the earth for longer period of time than the other geographical region of the earth. Figure 2 displays in general a satellite in an elliptical orbit. Figure2: Elliptical Orbiting Satellite Medium earth orbit is between 5000 km to 15000 km above the earth surface. While in low earth orbits, satellites revolve around the earth in circular orbit at about 400 km above the earth surface. Figure 3 depicts the low earth orbits (LEO) and medium earth orbits (MEO) of a satellite. Figure3: LEO and MEO orbiting Satellite Three types of services can be offered by a telecommunication satellite. First is FSS (Fixed Satellite Services), which is for long distance telecommunication services provided by different telecommunication networks on earth stations. Second is DBS (Direct Broadcast Satellite services), which is used for direct Television signals broadcasting from large earth stations. And third is MSS (Mobile Satellite Services), which is used to provide mobile communication services to different stations on earth. In the year 1976, Mobile Satellite Communication was started by Communications Satellite Corporation (COMSAT), which is a US based company belonging to the field of telecommunications. The communication satellites launched by them were called MARISAT (Maritime Satellites) and later an International Maritime Satellite organization (INMARSAT) was formed which now provides Mobile Satellite Communication Services [1]. Earlier satellite communication used to take place by routing calls and information from public landline to an earth station first, and then forwarding them to the satellite. But now mobile communication can take place directly between a satellite and a station or handset on earth. This entire phenomenon fantastically sounds simple but there can be few problems as well in using satellites for mobile communications. For instance, keeping the satellite in its orbit is not an easy task. The orbital motion does not depend only upon the earth’s gravitational pull. When a satellite is in its orbit, its orbit is also affected by the presence of other bodies such as the Moon and Sun. Moreover, our earth is not a perfect sphere so its own gravitational force on a satellite can vary at different locations and the Moon and Sun have their own gravitational forces as well that affects the path of a satellite. Under all these circumstances, satellites do drift from their original path which needs to be adjusted in order to keep the satellite on track. To transmit and receive signals, these telecommunication satellites have a number of antennas to receive signals from one mobile earth station and transmit it to one or more mobile earth station. There is a Doppler Shift as well in the transmitted signal which occurs because of the movement of the satellite and rotation of the earth about its own axis. Mobile communication satellite systems can provide services to those areas that cannot get services from networks on earth. These systems can be of three possible forms [2]. First is that a direct link to the gateway of satellite station can be given to a mobile earth station to connect to the network. Second is that a mobile earth station can be connected to a translator station through a radio link which is responsible to transmit the data from a mobile earth station to the gateway station through a satellite link. In the third type of mobile communication satellite system again a direct link can be provided to a mobile earth station but a dedicated satellite system would be required for this purpose. Different frequency bands are allocated to the satellites to perform mobile communication. Mostly used frequency bands are L-Band, C-Band, Ka-Band and Ku-Band. L-Band has the uplink frequency of 1.6 GHz and a downlink frequency of 1.5 GHz for commercial mobile satellite services (MSS). The long wavelength of this band allows it penetrate building structures and also get least affected by rain. Therefore, less powerful antenna transmitters are required. C-Band has the uplink frequency of 6 GHz and a downlink frequency of 4 GHz. Ka-Band uplink and downlink frequencies are 30 GHz and 20 GHz respectively for commercial use of mobile satellite mobile services and 44 GHz and 20 GHz of uplink and downlink frequencies for military use. This band has very large spectrum and high bandwidths available. But due to short wavelengths, it is largely affected by rain. Therefore, to increase the signal power very high power transmitters are required. On the other hand, Ku-Band has the medium range of frequencies. The uplink frequency is 14 GHz and downlink frequency is 12 GHz for fixed commercial use. Due to medium wavelengths, its signals can also penetrate many structures and are still able to provide high bandwidths but still they are affected by rain. As the earth terrestrial networks, satellites are also required to serve a number of users simultaneously. So at a time when millions of users are accessing satellite services there is a need to have some sort of mechanism to differentiate and secure each user’s transmission. For this purpose, there are a number of multiple access schemes of which the three most commonly used are TDMA (Time Division Multiple Access), FDMA (Frequency Division Multiple Access) and CDMA (Code Division Multiple Access). In TDMA, there are different time slots. Each mobile earth station transmits its data in chunks in a specific time slot at the same frequency. So the data of each user is differentiated in different time slots. In FDMA, different frequency bands are allocated to different users for both the uplink and downlink channels. However, TDMA is a better because of its lower distortions of inter-modulation. In FDMA, downlink bandwidth is divided among a number of users whereas in TDMA full downlink bandwidth is available to all users during a specific time slot allocated. Also in FDMA, we may have to decrease transponder power by one half to minimize the distortion due to inter-modulation. The third most commonly used multiple access scheme CDMA has no restrictions as in TDMA and FDMA. Each user can transmit its data at any time and can also use the same frequency bandwidth. In CDMA, each mobile earth station’s transmission is separated by a unique code. Signals transmission are separated by using spread spectrum technology that is why CDMA is also called Spread spectrum Multiple Access. Spread spectrum scheme assigns to each mobile station a unique code to generate a pseudorandom sequence to separate signals transmission and to spread the transmission across the whole bandwidth available from the satellite. When the signals transmission arrives at the receiver, it can be extracted by using the same sequence generated initially. The only limitation of the CDMA scheme is that it is very expensive to implement and can support a very limited number of mobile earth stations at a time. As the science has advanced in technology, there are a number of mobile communication satellite systems now. Now we have a look at the different mobile communications satellite systems that exist today. These mobile communication satellite systems are divided into three groups namely: Geo-Stationary Systems, Big Low Earth Orbit (LEO) Systems and little Low Earth Orbit Systems. In Geo-stationary systems, INMARSAT and MSAT are the two satellite systems that we have. In Big LEO systems we have IRIDIUM, ARIES, ELLIPSO and ODYSSEY satellite systems. For little LEO systems we have LEOSAT, STARNET, ORBCOMM, and VITASAT satellite systems. Of these satellite systems, International Maritime Satellite (INMARSAT) System is a very well known global mobile satellite telecommunication system. These satellite systems are connected to PSTN (Public Switched Telephone Networks) and they provide connectivity and communication services to a mobile earth station all over the world. Which means a user with a satellite mobile handset connected to the INMARSAT satellite system can receive services while roaming in any part of the world without being dependent on local terrestrial public networks. So a satellite connection proves to be really helpful in case something goes wrong with the terrestrial network such as a natural disaster etc. INMARSAT is running its operation on four geo stationary satellites providing global coverage namely: INMARSAT-A, INMARSAT-M, INMARSAT-B and INMARSAT-C. High quality telephone, fax and high speed data services are provided by INMARSAT-A satellite system. In addition to dialling to a telephone or fax number directly, it can also provide image and video transmission services. INMARSAT-M provide services at a much cheaper rate as compared to INMARSAT-A. It has a fully digital and portable terminal to provide high quality cellular voice and data transmission services. Additional functionalities are added in INMARSAT-B satellite system compared to INMARSAT-A at a much lower charges. Along with new services, it provides very high quality voice services and very high data rates with a scope to increase them further in future. INMARSAT-C comes as a low cost communication system with a light weight terminal powered by a battery. It comes with a small personal computer to communicate with the network headquarter whenever needed. The following Figure 4 shows the statistics of the INMARSAT satellite systems all over the world [3]. Figure 4: INMARSAT Satellite System Coverage and Service Providers [3] Iridium Satellite System was proposed and developed by the Motorola Company in collaboration with a few other companies. This satellite has been purchase by the Iridium, Inc Company. In this satellite system, satellites are set into orbits in 6 different polar orbital planes with a total of 72 satellites at about 780 km above the earth surface [4]. Satellites are divided into groups of 11 with equal distance among them.   These are all Low Earth Orbit Satellites. L-Band frequency band is used by mobile earth stations to access satellite link using TDMA or FDMA schemes. Access of the mobile stations need to be synchronized to enable them to transmit and receive in the same time frame slot. Each satellite can handle more than 1000 calls at a time. All the satellites can route traffic to each other as well. This satellite system is designed in such a way that global coverage is achieved and gateway stations, which need to be connected to public switched telephone network on earth, req uired are less in number. Two other LEO satellites systems are ARIES and ELLIPSO which are set into circular orbits above the equator to provide low cost services. Another very well known satellite system is GLOBALSTAR system which provided full global connectivity. This system consists of 48 satellites divided into groups of 6. These satellites are set into orbit in eight different planes at 1414 km above the earth surface and are inclined at 45degrees and 135degrees to the equator. There is no exchange of data among these satellites as in the Iridium System. Therefore, a mobile earth station can only get access to the satellite link when the satellite has a line of sight path to the gateway earth station. Mobile stations can access the satellite using L-Band frequency band. Code division Multiple Access (CDMA) scheme is used to separate transmission of each mobile station. Six spot beams are used to cover the same geographical area on earth as is required by the Iridium satellite system. Satellites in GLOBALSTAR system complete their lifecycle between 5 to 15 years. OrbComm launched its first two satellites in 1995. This satellite system is capable of providing remote monitoring and mobile tracking along with many other commercial services. OrbComm also contains 48 satellites which are in Low Earth Orbits. Access by mobile earth stations to these satellites is made on VHF (very high Frequency) band. The uplink band is 148 MHz to 150 MHz and the downlink band is between 137 MHZ to 138 MHz. Signal and data transmitted from the satellites are not directly forwarded to hand held devices first, rather they are first diverted to the gateway station on earth or public switched telephone network and then they are forwarded to mobile handsets. Satellites in this system have a lifecycle of about four years. Intermediate Circular Orbit (ICO) satellite system consists of ten satellites with the help of which it can provide full global coverage. These satellites are divided into groups of five into two orbital planes at about 10,355 km above the earth surface. They orbit the earth the earth in about 6 hours serving a geographical area on earth for 20 minutes. Each satellite in the Intermediate Circular orbit can provide up to 4500 channels for voice data traffic and access to these channels is made secure and reliable by using the Code Division Multiple Accessing (CDMA) scheme. The terminals ICO systems are capable of supporting dual mode which means that they can operate with satellite and as well as public switched telephone networks. In this entire scenario, each type of satellite system has its own advantages and disadvantages. Geo-Stationary satellites can be useful for one form of mobile communication but in some scenarios it may be more feasible to use Low Earth Orbit satellite system. Like with the help of three Geo-Stationary satellites we can provide almost full global coverage. As the satellites remain at the same point above the earth in Geo-Stationary system, the transmitters and receivers can have the fixed antenna positions without the need to keep track of the satellite which at times can become a very tedious task. Because they are located at about 36000 km above the earth, they are less affected by the atmosphere around the earth during its orbit making its life cycle greater than the other satellite systems. On the other hand, there are certain disadvantages of the Geo-Stationary system as well. Besides almost having no coverage at the north and south poles, one of the biggest problems in this sys tem is performing voice and data communication over these satellites. Because they are far away from earth’s surface, there is very high latency or delay in the transmission and reception which makes it unfeasible for voice traffic. And also because of its large distance from earth’s surface, very high power antennas are required for these satellites which consumes a significant battery power. Moreover, sending a satellite into a Geo-stationary orbit from earth is very expensive as compared to other Low Earth Orbit satellites. While with the Low Earth Orbit (LEO) satellite systems, transmission rates of about 2.4 kbps can carry out voice data communication efficiently. Because these satellites are orbiting the earth at much lower altitude as compared to Geo-Stationary satellites, transmission power required for the antennas is much less which in turn saves the overall battery power consumed. And for the same reason, the delay or latency in the transmission is much less which can compete with the wired cable terrestrial networks on earth. Higher elevation of these satellites to the equator enables are better coverage at the north and south poles. And also because the geographical area covered by one satellite in LEO system is smaller; frequency reuse policy can be best utilized. On the other hand, the very obvious and possibly the one of the biggest problem with this satellite system is the need to have a large number of satellites to provide global coverage. As the satellites in this system do not stay at a fixed position over the earth surface, their serving time geographical is only about 10 to 15 minutes which require very complex antenna mechanism on earth to keep track of the satellites. Another disadvantage of having low earth orbits is the very short lifetime of a satellite. Friction from earth’s surrounding atmosphere can severely effect the lifetime of a satellite in LEO satellite system. If a satellite mobile user is roaming around the world, providing global connectivity to that user also require interconnectivity of these large number of satellites. Mobile Communication Satellite Systems are evolving very quickly in this era to keep pace with the increasing demand of communication globally. The trend is shifting towards the LEO satellite systems from the Geo-Stationary satellite systems because of very less latency delays in LEO systems as far as voice data communication is concerned. However, these satellite systems cannot fully replace the need of terrestrial networks because of these systems are still very expensive for an average user and not all countries of the world are developed enough to cope up with these satellites systems.

How Santas Reindeer Got Their Names

How Santa's Reindeer Got Their Names If you ask the average American to name Santas reindeer, the first name to pop up will probably be  Rudolph  (the Red-Nosed Reindeer). The next two would no doubt be  Donner  and  Blitzen. But is this correct? And where did these names come from? Origin of Reindeer Names The popular Christmas song  Ã¢â‚¬Å"Rudolph the Red-Nosed Reindeer† was a 1949 hit tune sung and recorded by Gene Autry and based on a character originally created by a marketing team for Montgomery Ward in 1939. The lyrics were written by  Johnny Marks, who borrowed most of the reindeer names from the classic 1823 poem â€Å"A Visit from Saint Nicholas† (more commonly known as â€Å"Twas the Night before Christmas†) by Major Henry Livingston, Jr. (Historically,  Clement Clarke Moore has been credited for the poem, but most scholars now believe Livingston to have been the poet.) The original poem refers to â€Å"eight tiny reindeer† (Rudolph actually makes it nine tiny reindeer) and names them: â€Å"Now Dasher! now, Dancer! now Prancer and Vixen!/On, Comet! on, Cupid! on Dunder and Blixem!† Later Versions Dunder and Blixem? Youve always heard Donner and Blitzen, right? The former were Dutch names written into the poem by Livingston. Only in later versions, modified by Moore in 1844, were the two names changed to German:  Donder  (close to  Donner, thunder) and  Blitzen  (lightning), to better rhyme with Vixen. Finally, for some reason, in the song â€Å"Rudolph the Red-Nosed Reindeer† Marks turned Donder into Donner. Whether Marks made the change because he knew German or because it just sounded better is uncertain.* In any event, there is certainly some logic in using German  Donner  and  Blitzen  (thunder and lightning) for the names. Since 1950 or so, the two reindeer names have been  Donner  and  Blitzen  in both â€Å"Rudolph the Red-Nosed Reindeer†Ã‚  and the â€Å"A  Visit  from Saint Nicholas.

Globalization Essay Example | Topics and Well Written Essays - 1000 words - 1

Globalization - Essay Example Fashion images projected in the films, magazines, television, and the Internet have created a global style that has spread across different cultures and geographic boundaries. T-shirts, blue jeans, baseball caps, and athletic costumes are traded everywhere from China to Manhattan, and to the African villages. Fashion systems in Asia, Africa, and the West borrow different kinds of textile elements and styles from one another. All these styles are housed under one roof in the large shopping malls in the rich countries. These products gain the attention of customers belonging to all age-groups, ethnicities, genders, cultures, and professions like high-tech global bazaars. This trend of the homogenizing effect across countries and cultures as well as the increased variety of costumes and accessories within the geographic locations reflects a global paradox. Although the shopping malls in different countries across the world have similar stores and the products sold are same, yet every si ngle item has a huge variety. There is a seemingly baffling and infinite variety of cuts and fits in jeans both for men and women, ranging from the billowing baggy style to the stretched tight jeans, and from tapered at the ankle jeans to the bell-bottom jeans. Different styles have been developed to suit the individualistic needs of men and women belonging to different age-groups, and having different heights and physiques. â€Å"While a somewhat baggy, â€Å"relaxed† cut can signify dignified middle-aged femininity, a baggy cut taken to excess can signify hyper-masculine ghetto street smarts. Each variation takes its turn as an ephemeral and arbitrary signifier of shifting identities based on age, gender, ethnicity, or subculture† (â€Å"Globalization†). These days, the Fashion week in different cities around the world including Oslo, Berlin, Lahore, and Kiev are the same. The Fashion week was first organized in 1943 in the New York City. In those days, it was not possible for the Americans to visit Paris to know the latest trends in fashion. The objective of the organizers of the event was to attract the American designers. Fashion weeks are events in which both national and international designers get an opportunity to display their works which not only helps them gain the media attention but also earns them millions of tourist dollars in revenue. Proliferation of the fashion weeks all over the world is a potential sign of globalization of the fashion industry. These days, the most impressive fashion weeks are annually organized in London, Paris, New York, and Milan. The fashion industry grew by leaps and bounds as the fashion weeks were started to be organized in the Islamic countries. In the year 2006, the first fashion week was organized in Tehran. This fashion week featured modestly dressed women. The models wore hijabs, abayas, gowns, and other Islamic outfits in bright colors and prints. In the same year, fashion week was arrange d in New Delhi which featured 60 designers. Out of the 160 buyers who were attracted by the event, over 70 were international. The event earned the organizers profit worth $50 million. Globalization of the fashion industry reached its apogee with the use of the Internet. Internet not only spread awareness about the latest fashion trends, but also enabled the consumers to shop the latest

Understanding, Explaining, and Eliminating Sexual Harassment by James Essay

Understanding, Explaining, and Eliminating Sexual Harassment by James P. Sterba - Essay Example Sexual harassment can occur between two people of the same gender. Various people have tried explaining sexual harassment. Most people believe that sexual harassment is caused by a wide variety of factors. Cultural factors, social factors and personal psychological factors are believed to be the main causes of sexual harassment. Some cultures believe that women should always be submissive to men. As a result men hailing from such cultures tend to believe that they can have their way with women. Such men will go forcefully touching and grabbing women, which constitutes to sexual harassment. Indecent behavior is also one of the main causes of sexual harassment. Some men and women are guilty of dressing inappropriately in the workplace. This tempts the members of both the opposite sex and same sex. This can lead to the sexual advancement and sexual coercion. Lack of moral values may also cause sexual harassment. Some people are brought up in society where acts of sexual harassment are not condemned. Such people will have a problem in the future adapting to what is considered morally right by the larger society (Boland 78). There are people who also tend to believe that one gender is superior to the other. Such people discriminate against members of the other gender. They end up verbally abusing or forcefully touching the members of the other gender. Research has shown that women are more vulnerable to sexual harassment at the workplace due to the fact that they often lack power. They are afraid of losing their jobs and will not report the incidents of sexual harassment. Most men also use their powerful roles in the organizations to solicit for sexual favors from women for in exchange for work related benefits. Economic and social changes in the recent past have resulted in women taking up powerful positions in many organizations. Some men feel intimidated by this fact and resort to harassing such women in their workplaces. Many

The Difference Between An Egalitarian And A Non-Egalitarian Principle Essay

The Difference Between An Egalitarian And A Non-Egalitarian Principle Of Distribution. Which One Is Preferable - Essay Example In this philosophy, people ought to get the same, be treated equally, treat our friend as equal, and all people should enjoy equal social status. The egalitarianism principles rest on the background that all mankind are equal in fundamental worth and moral status. Although these principles are widely accepted, there exist variant views especially in Western European and Anglo American philosophical traditions. Egalitarians believe that equality and justice are closely well connected. Firstly, they think unfair life prospects should be equalized. Secondly, equality is the most important constitutive and intrinsic worth of justice. Thirdly, welfare has to be increased. Fourthly and fifthly that justice is comparative, and inequalities are just when advantages are destroyed in the name of justice respectively. One of the most important views of the existence of egalitarianism is the Christian doctrine that God loves all mankind equally despite their social economic status (Raz 254-257). The existence of egalitarianism is prudent for there are different types of equality. For example, treatment of people equally in the society. Great example is the modern democratic societies where everyone has equal chances to hold any position and be treated equally like any other person. An egalitarian denies Cross-Temporal Additivity because inequality is not additive over time. Inequality partly determines value and hence value is not additive over time. In economics, egalitarianism would mean equality to opportunity such that the government ought not to discriminate against citizens or even hinder prosperity opportunities to them. The government has to advocate for equal prosperity for all citizens. Milton Friedman a free-market economist supports equality-of-opportunity economic egalitarianism. The principles of non egalitarianism hold that equality is not bad or good at the same time, and there are several forms of egalitarianism depending on one’s interpretation of equality and values. The non egalitarian principle suggests that, value of two events is equal given that they occupy no overlapping times interval. This claim portrays people’s view of justice. The treatment of people justly depends on how other people are treated. Therefore, it is unfair to distribute resources if people are denied their share despite the amount to be given. What is important is the allocation ratio to each person and the kind of feeling that arise thereafter. Non-Egalitarianism uses three general moral principles namely: Intrapersonal Non-Egalitarianism, Strong Supervenience of Utility-Value and Cross Temporal Additivity of Utility Value. The Intrapersonal Non-Egalitarianism principle supports that the equality in the distribution of utility is evaluative neutral in an individual’s life. The Strong Supervenience of Utility-Value principle states that the two events have the same utility value if they are intrinsically identical in terms of non-evalu ative properties. Lastly the Cross-Temporal Additivity of Utility Value principle states that utility-value of fusion of for instance event A and B is equal to utility value of A plus utility value of B. This holds as long as the two events occupy non-overlapping time intervals. Scope and Role of Distributive Principles This principle varies greatly in various dimensions relevance to distributive justice (wealth, income, jobs utility among others). The variation between the egalitarian and non-egalitarian principle occurs in the nature of the recipient and the basis of distribution. It covers the distribution and economic burden among individuals in society. This principle forms the principles of Anglo

The Weed by Amrita Pritam Essay Example | Topics and Well Written Essays - 1000 words

The Weed by Amrita Pritam - Essay Example This paper illustrates that the story unfolds through the point of view of an unnamed narrator, obviously a city-bred and educated female. The main theme of the story is the vulnerability of women who fall prey to the lure of men, symbolized through the metaphorical weed, and how males exploit the females for carnal pleasure and then discard them. Right from the first line of the story, the author hints at the way women are treated in rural India by her reference to the â€Å"new bride of the old servant,† which connotes to the fact that older men in the country practice polygamy and that they can have younger wives. The author also suggests that under the patriarchal system that exists in the country, any father can give away his daughter to any man without the consent of the girl. Pritam presents the girl as a â€Å"delight to both ear and eye† and owning a body that redeems her â€Å"dark complexion†. In contrast, the author portrays her husband, Prabhati, as â€Å"old, short and loose-jawed,† which indicates that the society disregards the traits of a woman and by belonging to the stronger sex, men are automatically qualified to claim any woman. Unfortunately, Angoori is not the single female, who meets with a similar fate in the rural Indian society and it appears that many suffer at men’s hands in the same way. She relates the story of her friend, who absconds with her paramour, who later deserts her, to the narrator. The author tries to emphasize the issue of male exploitation of the females by referring to various aspects of the rural Indian culture, which is her major theme for the story. She uses the metaphor of the â€Å"weed† to underline the fact that males use some or other material element to win over the female hearts. In the case of Angoori’s friend, the weed comes in the form of sweets and betel leaf and in the protagonist’s case, it takes the form of sweetened tea. The men in all cases e xploit the women and after enjoying the carnal pleasure desert them. The exploitation of women in the rural Indian culture, thus, is a theme that is recurrently emphasized in the story. Pritam also deploys the literary device of imagery and irony profusely in the story to underline the theme of exploitation of females by males in the rural Indian culture. The author’s deft use of imagery to attain this purpose becomes evident from the episode where she equates Angoori’s body to â€Å"rightly kneaded dough, a baker’s pride† and describes her â€Å"rippling muscles impregnated with the metallic resilience of a coiled spring†. By using such imagery, the author provides the readers with a vivid picture a youthful and energetic female. On the other hand, Pritam talks about her husband as a loose-jawed old man, a stark contrast to the resilient and beautiful Angoori, for whom a husband is one whose feet a girl begins to adore when she is five or six. By dwelling on the protagonist’s beliefs such as this, the author wants to emphasize that women in rural India tend to acquiesce to men and they find contentment in it.

Markiting - Essay Example The two dimensions of the BCG model, market growth and relative market share, serve as proxies for industry attractiveness and competitive advantage respectively which are two important determinants of company profitability (â€Å"BCG Matrix† para 1). Looking at it from the product lifecycle point of view, it is often prudent for an organization to have a balanced product portfolio consisting of both high-growth and low-growth products. High-growth products are those that require greater resources and effort to market now but that have a high probability of generating immense revenues in the future, for example Apple could categorize the iPad here. On the other hand, a low-growth product is an already established product that brings the organization constant flow of cash for example in Apple’s case the iMac. The BCG model operates under two important assumptions. First of all, increasing market share leads to an increase in the generation of cash. The experience curve manifests that relative market share increases as a firm creates cost advantages (â€Å"BCG Matrix† para 2). Secondly, a growing market requires investment in assets to increase capacity which results in the consumption of cash.

The Weed by Amrita Pritam Essay Example | Topics and Well Written Essays - 1000 words

The Weed by Amrita Pritam - Essay Example This paper illustrates that the story unfolds through the point of view of an unnamed narrator, obviously a city-bred and educated female. The main theme of the story is the vulnerability of women who fall prey to the lure of men, symbolized through the metaphorical weed, and how males exploit the females for carnal pleasure and then discard them. Right from the first line of the story, the author hints at the way women are treated in rural India by her reference to the â€Å"new bride of the old servant,† which connotes to the fact that older men in the country practice polygamy and that they can have younger wives. The author also suggests that under the patriarchal system that exists in the country, any father can give away his daughter to any man without the consent of the girl. Pritam presents the girl as a â€Å"delight to both ear and eye† and owning a body that redeems her â€Å"dark complexion†. In contrast, the author portrays her husband, Prabhati, as â€Å"old, short and loose-jawed,† which indicates that the society disregards the traits of a woman and by belonging to the stronger sex, men are automatically qualified to claim any woman. Unfortunately, Angoori is not the single female, who meets with a similar fate in the rural Indian society and it appears that many suffer at men’s hands in the same way. She relates the story of her friend, who absconds with her paramour, who later deserts her, to the narrator. The author tries to emphasize the issue of male exploitation of the females by referring to various aspects of the rural Indian culture, which is her major theme for the story. She uses the metaphor of the â€Å"weed† to underline the fact that males use some or other material element to win over the female hearts. In the case of Angoori’s friend, the weed comes in the form of sweets and betel leaf and in the protagonist’s case, it takes the form of sweetened tea. The men in all cases e xploit the women and after enjoying the carnal pleasure desert them. The exploitation of women in the rural Indian culture, thus, is a theme that is recurrently emphasized in the story. Pritam also deploys the literary device of imagery and irony profusely in the story to underline the theme of exploitation of females by males in the rural Indian culture. The author’s deft use of imagery to attain this purpose becomes evident from the episode where she equates Angoori’s body to â€Å"rightly kneaded dough, a baker’s pride† and describes her â€Å"rippling muscles impregnated with the metallic resilience of a coiled spring†. By using such imagery, the author provides the readers with a vivid picture a youthful and energetic female. On the other hand, Pritam talks about her husband as a loose-jawed old man, a stark contrast to the resilient and beautiful Angoori, for whom a husband is one whose feet a girl begins to adore when she is five or six. By dwelling on the protagonist’s beliefs such as this, the author wants to emphasize that women in rural India tend to acquiesce to men and they find contentment in it.  

ASSIGNMENT Essay Example | Topics and Well Written Essays - 1500 words

ASSIGNMENT - Essay Example The â€Å"Book of Job† and the â€Å"Wisdom of Ben-Sira,† are two of the accounts of the Bible which greatly emphasized these two concepts. In this paper, Job’s challenge against ancient wisdom, proceeded by Ben-Sira’s justification about the goodness of God will be taken into account. What Victor Hugo has to say is a reminder of the literary magnificence of the Book of Job. Stating that if all forms of literature would vanish from the Earth, he would save the Book of Job, is a proof that the book is not only an ordinary piece of religious instruction, rather, a source of wisdom with eloquence in pronouncing the teachings of God. Basically, the purpose of the book is to answer the age old question about the nature of man’s suffering and why the righteous should suffer (Copeland 4). Although someone might argue the image of God presented in the Old Testament is an angry, punishing God, He is still the same loving, ever righteous and just God as in the New Testament. However, the great misfortunes of the wicked and the rigid test of faith in the persons found in the Old Testament might be the root of this misconception. Ancient wisdom contends that God is omnipotent and punishes whoever commits a violation of the Commandment. Job, on the other hand, is a man of good deed and yet, he suffered greatly. As a father and a faithful, he believes that God is all-powerful and acknowledges it through sacrifices and teaching his children about the greatness of God. Clearly, he was favored by God in giving him wisdom and wealth, but due to the afflictions made by Satan (with God’s permission), he has changeable convictions about the existence of humans and their relationship toward God. As stated, â€Å"Job questions the moral underpinnings of human existence, for he no longer receives proper dividends from above† (ABD, III, 862). Job complains about his innocent suffering. However, adjacent to his complaints are his own assumptions why such

“The Wife of Bath’s Tale” by Geoffrey Chaucer and “The Flea” by John Donne Essay Example for Free

â€Å"The Wife of Bath’s Tale† by Geoffrey Chaucer and â€Å"The Flea† by John Donne Essay In this paper I will compare the approach to marriage in the works â€Å"The Wife of Bath’s Tale† by Geoffrey Chaucer and â€Å"The Flea† by John Donne; in both cases it is a means to an end: in the first the old woman wants to get â€Å"the thing that most of all Women desire† and in the second the lover seeks â€Å"How little which his lover (thou) deniest him (me)† and uses an allusion to marriage to achieve this. In â€Å"The Wife of Bath’s Tale† the old woman seems to ask the knight a naà ¯ve request; there is no hint that what she will ask of him is to marry her: â€Å"Swear me true that whatsoever I ask of you, you’ll do it if it lies whithin you might†¦Ã¢â‚¬ . After the knight returns to the queen, and the answer the old woman gave the knight is the one the queen looked for, the old woman’s intent becomes clear: â€Å"Before the court I ask you, then, sir knight, To take me, as you wife.† The knight in shock tries to refuse, but as he has sworn â€Å"upon his (my) honor† he has no way out of the deal he closed; therefore, they get married. As married couples are due in the night of the wedding, the couple goes to bed to consummate the marriage. Here is when we learn what the old woman’s plan was. As they lay in bed they old woman is waiting for the knight to act as a newlywed husband, but she then realizes that the knight’s intentions were not the ones she hoped for: â€Å"You are so loathsome and so old as well†¦ †¦It is no wonder that I toss and turn.† The wife tells her husband that he has two choices, and he is welcome to choose what he best prefers, for she will do as he bids and never complain. The knight thinks carefully, and weighs his options, and then realizes that this choice should not be his: â€Å"My love and lady, my dear wife. In your wise government I put my life†¦ †¦I am content, whatever pleases you.† Now the old woman’s motive is clear, and she got â€Å"the thing that most of all Women desire† â€Å"to have sovereignty†¦ †¦above their husbands, and to have their way in love†; the choice is hers to do as she pleases, and what she wants is to please him, so she gives her husband everything he could have wanted. The decision she makes can be confusing since she denies herself the power she wanted after getting the choice, but the main point is that even so she was able to choose. In â€Å"The Flea† the man is not looking for marriage, he seeks only to consummate it. The allusion to marriage is used to undermine the importance of the act that comes after the wedding: the bedding. The poem starts with the comparison between both lovers being bitten by a flea, and the lover thinks that the act of being bitten by a flea is less than the consumption of marriage: â€Å"Yet this enjoys before it woo, And pampered swells with one blood made of two, And this, alas, is more than we would do.† The fact that they were bitten by the same flea means that they are as good as married. The lover tries to convince his mistress that what he wants is not sinful as she thinks since they are already married by the bite of the flea, so they may as well do what married couples do: â€Å"The flea is you and I, and this Our marriage bed and marriage temple is.† The woman is not convinced by his words, and tries to kill the flea, but her lover tries to convince her that this flea is them, and their love and marriage, and if she kills the flea, not only the flea will die: â€Å"†Three sins in killing three.† After the flea is killed by his lover, he finds a way to turn around the situation for his benefit, and tells her that the fact that flea is dead only shows that nothing is as important as it seems; therefore, why should not them lay together? She will lose as much as the flea lost which apparently she thinks it is not a lot: â€Å"’Tis true; then learn how false fears be: Just so much honor, when thou yield’st to me, will waste†¦Ã¢â‚¬  In this works the use of marriage although used for alternate purposes is given different meaning. In â€Å"The Wife of Bath’s Tale†, the old woman wants â€Å"the thing that most of all Women desire†, and is willing to do anything to get it; in â€Å"The Flea† the lover wants to lay with his mistress, and will say anything to convince her, even that they are â€Å"married† after being bitten by a flea. The use of the marriage in both stories is done differently since the old woman lures the knight into marrying her, so that she can get what she want, and the lover tries to convince his mistress they are already married in a sense, so that he will able to bed her. One may well say nevertheless that in both cases marriage is a means of leverage, a tool to be best used as the authors see fit, in order to allow their characters achieve their aims; whatever those aims might be. In these sense marriage gets a similar treatment in both stories.

Ricardian Trade Theory: Overview and Analysis

Ricardian Trade Theory: Overview and Analysis The Classical trade theory: Ricardian Trade Theory (Comparative advantage trade theory) Introduction Ricardian Trade Theory David Ricardo points out the Ricardian Model in 1817. Different countries had differences in productivity and technology. Hence, those differences would cause comparative advantage trade. There are two mainly points of Ricardian Model; firstly, the different rates of labor productivity between different countries had important position in international trade. Secondly, the model of trade is dependent on comparative advantage, not absolute advantage. On the other words, According to Evans, H. D (1989), comparing two countries, a country had absolute advantage in the production of two goods, and the other on was in absolute inferiority. The assumption is: the two goods had different productivity in both countries (one goods productivity is more efficiency than the other one in a country). The advantage country got comparative advantage in one advantage good, and inferiority country got comparative advantage in one disadvantage good. Both countries produce their comparative advantage go ods, moreover, both countries export the comparative advantage good and import comparative disadvantage good, then both countries could got benefits from this international trade. This is the principle of Ricardian comparative advantage trade theory. As lecture notes point out and Porter,M.E (1998) concluded, the Ricardian Comparative advantage trade theory is based on the assumptions followed: 1, there are only two countries, A and B. 2, both countries are only produced two goods. 3, when the goods were producing, there are different technology between two countries, A and B. Hence the different degrees of technology level affect different productivity and capital. 4, this model only got the goods to goods trade assumption. There is no complicate trading. (Both goods got same price, however the cost of production was not equal). 5, labor market supply was fixed. 6, labour can mobile inside the country, however, is not mobile across countries. 7, in countries, goods and markets are perfect competition. 8, there is no tariff and transportation cost. 9, productivity of labor is fixed. (Means the degree of technology would not increase during trading.) The theory generally assumes that the relative supplies of these two particular commodities are based on their relative productivity and technology. Hence, every country got varies productivity or technology; the endowments were the factor of their relative the productivity. This theory presented two countries are endowed with different level or degree of the production factors, and the naturally determined endowments, country would follow the endowments to trade the comparative advantage goods to the other one. These affect the two countries international trade more efficient and decrease the cost of capital for both countries. Moreover, with constant productivity, both countries could benefit from the free international trade even one country is in absolute disadvantage. Takumi Naito (2012) concluded the Ricardian model of trade and growth. He concluded from the assumption and gets one results: if two countries got larger comparative advantage, the benefit for both countries are ge tting huger. We can easily contact the relationship between advance country and developing country. With the simple example, United Kingdom and India trade with the grains and textile during the law of comparative advantage coming out. Hence, the textile production in UK requires less labour hours required in the grains producing: UK got the comparative in producing cheese. Same as India, India has comparative advantage producing grains. Therefore, there are gain from international trade if UK product the textile and India product grains. The Ricardian Model really proved UK free international trade in grains. Under those assumptions, Ricardian model ignores many product factors besides labor. David Ricardo explained the reason of international trade under different efficient of labor production. There are huge advantages for developing the international trade with this classic model. Firstly, this model comes from the law of comparative advantage, and help the United Kingdom got the solution to the grain crisis from 1815. Secondly, although Ricardian Model only showed its pedagogical importance, the classical emphasis on different productivity and the cost of labor has been utilized by the neoclassical focus on factor endowments. (Stephen S.G, 2000) thirdly, older tests, such as MacDougall, 1951 and Stern, 1962 were highly successful. Hence, it is valuable for us to know how this basic pedagogical model performs empirically with the large recent data. The empirical Validity of the Model and the Relevance of the Empirical Work In these parts, this paper would show the strengths and weaknesses of Ricardian Model, from the points of empirical. The core meaning as mention before: follow the law of comparative advantage; the country would to do specialized production for only one goods which is comparative advantage good. We cannot reject this theory points with the literature evidence; however, we could prove some empirical evidence to discuss the advantage and disadvantage for the international trade. Basic Ricardian Model The Ricardian Model focus on the technology and labour productivity. As the comparative advantage theory mentioned, the labour costs also is the important elements of this model. Now, based on the research of Stephen S.G (2000) we represent ‘Aa’ to the labor requirements of every single unit in country a, and ‘Qa’ is the value-added in country a. represent the ‘La’ as the labour employment in country a: We can see easily, the Aa is unit labor requirements, that means the value of Aa get higher, the productivity of country a getting lower. Hence, the main points of ricardian model are increasing total productivity of whole country, the Aa needed to lower. Coming from the assumption of Ricardian Model, the labour is fixed and not crosses to the other country. Therefore, the La is fixed, we keep the La constant. So, the productivity is dependent on the totally value-added Qa. Hence, we can conclude: Ricardian Model would success, there would be a huge enough different productivity between two countries. Or there would not gain from the free trade. We could also use b to represent the country b. hence, Ab, Lb, and Qb are all represent same means in country b. as the labour cost we can defined as the Ca and Cb. Then, Wa and Wb represent as the wage of employees in countries a and b. we assume the exchange rate between a and b is 1:1. We use ‘Rab’ as the rate of Ca and Cb. The function can be showed: We can see, if Rab smaller than 1, that means country a cost lower than country b, country a got comparative advantage good that should export goods. If Rab bigger than 1, that means country a should import goods. (All the functions are all represent one same good between two countries) From this function, we can see one possible: Rab is equal to 1. Hence, there is no comparative advantage between country a and b (the absolute advantage country got same rate in both goods with the absolute disadvantage country), which means, there is equal disadvantage and equal advantage. This is one of the disadvantages of Ricartian Model. Empirical work of Ricardian Model With the basic Ricardian Model, we could learn from the empirical studies to find out the strengths and weaknesses. First of all, this paper would discuss the empirical theory from MacDougall (1951). This case study used the ratio of US exports to UK exports. The dependent variable can be presented as both exports. And he used the productivity as the main independent variable. He used the total exports between US and UK. He collected 25 industries from UK and US in 1937. With his findings, he set the hypothesis: the wage rate is the same level as the labour productivity between US and UK. He used the 1937 data; those data showed US wage rate is double to UK wage rate. And we can follow the function in top; there is same reason that US got the comparative advantage in exports. Then he used the simple measures, he found the results that 20 of the 25 products follow the ratio. There are bigger than one. Hence the results are support the Ricardian Model. Secondly, the case study of Stern (1962) same as MacDougall, they both compare the totally exports between US and UK during different periods. And both used the productivity as the main independent variable. The results is 33 of the 39 sectors follow this ratios, as same as results of MacDougall could support for Ricardian Model. Thirdly, case study of Balassa (1963) points out the bilateral trade from UK and US to the third markets. Different with Stern and MacDougall, he relative both labor cost and productivity as explanatory variable. With the bilateral trade, there are three characteristics: speed fast, huger scope and sustainable sequencing. With the Song (1996) points out, there are some problem between the Balassa studies, which is the transportation cost and the tariffs. Under the developing countries, there are huge different between the tariffs and transportation cost. The only way is to fix the free trade strategy to bilateral trade. tariffs and transportation cost are ag ainst the assumption of Ricardian Model. With the bilateral trade, Balassa chose the data from 1950 to post 1970. As the results, this is also can prove the prediction of Ricardian Model. Although the bilateral trade is following the comparative advantage, this paper would use the overall export ratio of Stephen (2000) as in MacDougall and Stern. The radio is exports to third markets. Stehen choose 39 manufacturing sectors from 1970 to 1990. He got the database from OECD Structural Analysis Industrial (STAN) and Bilateral Trade (BT). Figure one and two are showed. He collected the purchasing-power-parity (PPPs) exchange rate. There are three PPPs shows on second Figure, frist is common PPPs, Second is sector-specific final expenditure PPPs from ICP, and last is sector-specific manufacturing PPPs from ICOP projects.

Differences Between Bureaucrats And Aristocrats In Government :: essays research papers

Bureaucrats and aristocrats, the former evident in the government in the Tang dynasty (617-907) and the ladder pronoun in the government of Heian Japan. Both are different in many different aspects, such as within government, government structure, law, economy, and society.A bureaucrat can be defined by the following: an appointed government official with certain duties and responsibilities defined by disposition in the bureaucracy. A bureaucrat is more dependent on the government than an aristocrat because official power comes from official appointment through the bureaucracy (Class Lecture, Oct. 16, 97). Bureaucracy first replaced aristocracy in the Tang dynasty, under the rule of Empress Wu (625?-706?, r.690-706) bureaucracy was expanded by furthering expansion policies and supporting the examination system. Positions in government were filled through the examination system, and people who passed were called the literati. When one held this title of literati, you were considered intelligent and were considered to have high status (TA session, Oct. 28, 97). "They were a group of smart guys with a good education." (Steve, TA session, Oct. 28, 97). This of course deprived the hereditary aristocracy of power 'they had enjoyed during the period of division, when appointments had been made by recommendation, and opened government service to a somewhat wider class of people...' (Schirokauer, p.103). For the first time, men who entered office through examination could attain the highest office, even that of Chief Minister. Examination graduates earned (earn being the operative word) prestige, and even though officials still entered government by other means such as family connections, at the same time the literati and thus the bureaucrats were gaining authority, jurisdiction, and power. And thus, one could see this shifting of supremacy from the aristocracy to the bureaucracy.Government in the Tang dynasty was regulated by the Tang legal codes, a system of laws written by legalists which consisted of a system of rewards and severe punishments (TA session, Oct. 28, 97). These legal codes were administrative: reporting what the state could do and what the subjects could not do. This is an important point in that, this showed the subjects possessed little power, the Tang legal codes are the opposite of any laws of present day, these legal codes protected the government and not the people. Government needed the subjects only to provide for taxes (revenue), labour (grain) and military (soldiers) reasons. 'A dead subject was not as useful as a living subject.
