European Airlines 1993-1997 Essay

⇠¨ Back ground and PEST analysis For many years, European Airlines are considered to be feed by the government. Before 1990s, the introduction of deregulation, this market was highly controlled by the government. Automatically, the result is high price as well as poor management and service. Consumers, of course, complained about the bad perform of them. Like most of the state-owned businesses, although some of the airlines intended to lower their price by cost cutting, redundancies and reorganization because of the increasing competition pressure, most of them failed because of the government interfere and strong labor reaction. Back in 1978, Airline deregulation first introduced to Americans. The new act allowed new airlines to come, permitted them to choose lines individually and release the pricing power. Till 1993, the price had decreased about 20%. A highly profitable service, transcontinental long haul flying, had exceeded 35% of the total. There in another one thing needs to mention: U.S. applied aggressive strategy, which is considered illegal in Europe. Refer to the fifteen years innovations in U.S, European politics finally made up their minds to repeal their restrictions in 1993. It is predicted that the European airlines environment might be completely open up in 1997 hopefully. In other words, there is five years for domestic airlines to adjust their strategies. Poter’s 5-force model âž ¢ The extent of competitive rivalry/industry competitors. Considering European market as a whole, the threat comes from airlines of other continents. This refers to those except cross-Europe and domestic routes. If we choose one airline specifically, for example Lufthansa airlines, its competitors most are inside the Europe. (E.g. British Airways, Deutsche BA, Air France, Alitalia etc. Further more, it was also threaten by some new entrants âž ¢ The threat of potential new entrants This involves airlines that ready to enter during this period. Generally speaking, these new entrants are relatively small size but more flexible. It does not have much burden of either the government or labor responds. As a result, they usually have low-cost so that the price might be even half less than the original ones. As a small size of the firm, their service is usually short haul and has constant demand of customers. âž ¢ The bargaining power of buyers This refers to organization/individual who buys the service. They are price/service sensitive. âž ¢ The bargaining power of suppliers Before deregulation the suppliers are disjointed with the airlines. Being centrally controlled by the government, either suppliers or airlines cannot fit efficiently and effectively. However, both sides might be automatically matched after they are release from the control. This will be mentioned later. âž ¢ The threat of substitutes Here means some other transport tools that cause airlines loss their consumers. ⇠¨ Analysis of Strategy Look back to the U.S. strategies. The whole model was set up based on a mass computing network, complex operating technique and pricing system, large investment and continuously attention to cost cutting. However, although this serious of activities are effective and improve the productivity and investment ability, it does not exceed the increasing marketing pressure. Potentially, these tactics might fit for specific European airlines, but not all of them. Except the political factors as I have mentioned before, another problem is that most of the companies operate separately form check-in to maintaining the motor. What they really need is set up a new competitive strategy in order to reorganize the business structure with their core ability.

Contents: UNIT 1, UNIT 2, UNIT 3, UNIT 4, UNIT 5, UNIT 6, UNIT 7 RNSIT UNIX SYSTEM PROGRAMMING NOTES UNIT 1 INTRODUCTION UNIX AND ANSI STANDARDS UNIX is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Do uglas McElroy and Joe Ossanna.Today UNIX systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations. The ANSI C Standard In 1989, American National Standard Institute (ANSI) proposed C programming language standard X3. 159-1989 to standardise the language constructs and libraries. This is termed as ANSI C standard. This attempt to unify the implementation of the C language supported on all computer system. The major differences between ANSI C and K&R C [Kernighan and Ritchie] are as follows: ? Function prototyping ? Support of the const and volatile data type qualifiers. Support wide characters and internationalization. ? Permit function pointers to be used without dereferencing. Function prototyping ANSI C adopts C++ function prototype technique where function definition and declaration include function names, arguments’ data types, and return value data types. This enables ANSI C compilers to check for function calls in user programs that pass invalid number of arguments or incompatible arguments’ data type. These fix a major weakness of K&R C compilers: invalid function calls in user programs often pass compilation but cause programs to crash when they are executed.Eg: unsigned long foo(char * fmt, double data) { /*body of foo*/ } unsigned long foo(char * fmt, double data); eg: int printf(const char* fmt,†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. ); External declaration of this function foo is specify variable number of arguments Support of the const and volatile data type qualifiers. ? The const keyword declares that some data cannot be changed. Eg: int printf(const char* fmt,†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. ); Declares a fmt argument that is of a const char * data type, meaning that the function printf cannot modify data in any character array that is passed as an actual argument value to fmt.Volatile keyword specifies that the values of some variables may change asynchronously, giving an hint to the compiler’s optimization algorithm not to remove any â€Å"redundant† statements that involve â€Å"volatile† objects. char get_io() { volatile char* io_port = 0x7777; char ch = *io_port; /*read first byte of data*/ ch = *io_port; /*read second byte of data*/ } ? eg: If io_port variable is not declared to be volatile when the program is compiled, the compiler may eliminate second ch = *io_port statement, as it is considered redundant with respect to the previous statement. Prepared By: RAJKUMAR [Asst. Prof. ] & DIVYA K [1RN09IS016] Page 1 RNSIT UNIX SYSTEM PROGRAMMING NOTES The const and volatile data type qualifiers are also supported in C++. Support wide characters and internationalisation ? ? ANSI C supports internationalisation by allowing C-program to use wide characters. Wide characters use more than one byte of storage per character. ANSI C defines the setlocale function, which allows users to specify the format of date, monetary and real number re presentations. For eg: most countries display the date in dd/mm/yyyy format whereas US displays it in mm/dd/yyyy format. Function prototype of setlocale function is: ? #include char setlocale (int category, const char* locale); ? The setlocale function prototype and possible values of the category argument are declared in the header. The category values specify what format class(es) is to be changed. Some of the possible values of the category argument are: category value effect on standard C functions/macros LC_CTYPE LC_TIME LC_NUMERIC LC_MONETARY LC_ALL ? ? ? ? ? Affects behavior of the macros Affects date and time format. Affects number representation format Affects monetary values format combines the affect of all above Permit function pointers without dereferencing ANSI C specifies that a function pointer may be used like a function name.No referencing is needed when calling a function whose address is contained in the pointer. For Example, the following statement given below d efines a function pointer funptr, which contains the address of the function foo. extern void foo(double xyz,const int *ptr); void (*funptr)(double,const int *)=foo; The function foo may be invoked by either directly calling foo or via the funptr. foo(12. 78,†Hello world†); funptr(12. 78,†Hello world†); K&R C requires funptr be dereferenced to call foo. (* funptr) (13. 48,†Hello usp†); ANSI C also defines a set of C processor(cpp) symbols, which may be used in user programs.These symbols are assigned actual values at compilation time. cpp SYMBOL USE _STDC_ Feature test macro. Value is 1 if a compiler is ANSI C, 0 otherwise _LINE_ Evaluated to the physical line number of a source file. _FILE_ Value is the file name of a module that contains this symbol. _DATE_ Value is the date that a module containing this symbol is compiled. _TIME_ value is the time that a module containing this symbol is compiled. The following test_ansi_c. c program illustrates the use of these symbols: #include int main() { #if _STDC_==0 printf(â€Å"cc is not ANSI C compliant†); #else printf(â€Å"%s compiled at %s:%s.This statement is at line %d †, _FILE_ , _DATE_ , _TIME_ , _LINE_ );

How Fast Food Affects Child Obesity

Obesity has become and increasing problem in the United States for the past few years. Not only has it affected adults but now children at an alarming rate. Fast food is the cause of a lot of overweight children and needs to be addressed immediately. According to CBS news, billions of dollars each year are spent buying fast food. Parents have become lazy when it comes to providing their children with basic essential nutrients. I feel as though children are becoming more overweight because they’re eating very fattening foods and not having any extracurricular activities. Schools must become more aware of the situation and make physical education a priority. If certain schools don’t enforce physical education then the parents have to involve their children in after school activities. CBS news expresses concern that children are becoming more prone to serious health risks and life altering illnesses because of obesity. Fast foods are filled with high doses of sugar, fats, starch and salts which are served in large portions. Rutuja Jathar feels consumers are tricked by fast food companies because of their low prices but evidently are paying a high price when it comes to their health. I have seen documentaries and reality shows such as supersize me, fast food nation and the future of food which talk about overweight children and adults who are constantly eating fatty foods and drinking large amounts of soda every day. Parents do not realize the amount of damage they are causing and potentially leading their child to death. I believe that children who are overweight are not only affected physically but emotionally and mentally. Based on personal experiences children who have been overweight for majority of their lives are more likely to become depressed, teased and may lead to other dangerous routes such as suicide. To support my statement an article called â€Å"Childhood Obesity: Effects on your Child† says being overweight can cause low self esteem, behavior and learning problems, stress and anxiety, comfort eating and depression. They become very self conscious and shy because they feel as though people will look at them differently due to their weight. Children who are obese are not to blame; it’s the parents who are at fault. A child only does what their parents allow them to do. Children do not have money to go out and buy these foods for their selves; their parents to do it. Parents need to become more responsible when it comes to what their children are eating. A child does not know any better but their parents do. According to Rutuja Jathar’s article studies show that boys and girls between the ages of four and nineteen eat fast food on a regular basis. That would includes fattening foods not just from McDonalds but from restaurants such as Friday’s, Chili’s, Cheesecake Factory, etc. It is my belief that parents are enabling their children to live unhealthy lives which will lead them on a path of never ending health issues. Also children are still growing so they need the essential vitamins to help with their growth. An article posted by Michael Adams say that statistics are showing that between 10% and 15% of children within the United States are overweight and does not include the ones who are at risk of becoming overweight. He also discusses other factors that contribute to children being overweight such as television, video games and advertising. Interesting enough he talks about most parents living hectic lives so in many cases they don’t have time to prepare a healthy meal and therefore resort to fast food. It continues saying the bad part about it is that parents who have that hectic lifestyle end up making it an everyday routine where their children are eating fast food. Adams makes an important point stating that if a child wants a double cheese burger, a large order of fries and coke that child will end up consuming 1340 calories and 53 grams of fat in one meal. Adults are to consume 2,000 calories a day and children less than that. Basically what Adams is trying to say is childr en are eating a whole days worth of calories and fat in one meal. To relieve this crisis parents can look at more creative ways of serving their kids healthier food. Rutuja Jathar says that fast food doesn’t make a child full, but because of the high amount of starch in the servings they will only become hungrier. As a result they will acquire more weight. An idea that parents can use to get their kids eating healthier is to make them involved with preparing their own meals. This way kids will be more motivated to eat the healthier choice and will feel a sense of accomplishment. Instead of frying the foods try to use healthier methods of cooking such as baking and broiling. Also like I stated earlier getting children involved in extracurricular activities will help kids burn off the carbohydrates and fat. To conclude child obesity is becoming an increasing issue. Children who are growing up in today’s society who are obese are most likely to be obese into adulthood. We have to stop making excuses as to why this problem is what it is. These children are not adding value to their lives and can die at such young ages. Fast food plays a large role in the amount of overweight children but it is not to blame. Parents are responsible for the livelihood of their children and must do better. Doctors must do better also when it comes to educating parents about the important nutrients and foods their children need stay healthy. Our society needs to encourage kids to become more active and choose healthier eating habits. The children are our future and without them there wouldn’t be one.

Foods in America Essay Example | Topics and Well Written Essays - 250 words

Foods in America - Essay Example Although these dried foods are used to give flavor to dishes, I still eat them raw and at times I fry them as snacks. One of my favorite dishes made from dried foods is Pemmican. This dish is made up of dried berries, nuts, and meat. What I like about this food is the fact that it is very handy and convenient because you could eat it without cooking it first. You can eat it anytime you want. Yet, there are some American Indian foods that I do not like that much. One of those I like the least is their smoked foods. Although I like dried foods, I still find the taste of smoked foods quite unpleasant, especially the smoked salmon. I find it too salty and fatty. I think smoking foods is best for preparing and preserving food, but not as an actual dish. Even so, I really like most of American Indian foods. They are natural, healthy, and savory.

Entrepreneurship and Venture Creation Assessment Essay

Entrepreneurship and Venture Creation Assessment - Essay Example The business idea is to develop a business that connects buyers and sellers of any product, from clothing, kitchenware, electronic, cars, household items, and any other items that have market value. The idea aims to capitalise of individuals who have used items and hopes to make quick cash out of the sale. Unlike existing ideas that champions the capability of the seller has to meet the potential buyer, this idea will ensure both option of the two meeting or the seller decides to use the organisation’s sale representative to do the transaction on their behalf. The use of technology has made it possible to make online transactions. People can make secure purchase of items by just keying the details of their credit cards and select the mode of delivery and the destination to receive what they have purchased. The model will utilise these technological provisions to connect buyers and sellers of different items from different geographical locations. Other than making use of technology for efficient implementation of the model, the main source of this motivation is the strong marketing strategy, which will enable the idea get the wide coverage (Cromie, 2000). Besides, the realisation that most homes have used items that other people may find useful at a reduced pricing is the motivation guiding these ideas. In every household, there are items ranging from clothing to other assets that the owner can generate some quick cash by selling them using a platform that will not cost them lots of money. These ideas are realistic because the less fortunate community values second hand goods. For instance, charity organisations and other humanitarian organisations may wish to purchase less expensive goods but find it difficult to outsource for such items. The example given above is not the main source of the customers, but just a perspective to illustrate how realistic nature of the model. The main customer targeted by this

Economic arguments for further enlargement of the EU Essay

Economic arguments for further enlargement of the EU - Essay Example The paper tells that the enlargement of the EU is one of the most debated topics presented to relevant councils. When the European Union was first formed in 1952 there were only six member countries. Today, there are 27 member countries in the European Union, and this number is scheduled to be increased in 2013. The European Union has been inducting newer countries into its council on an irregular basis since 1952, after subjecting applicant countries through a long process requiring pre-accession treaties, assessment conditions and a set of criteria – the Copenhagen criteria – that must be met before membership is granted. The process can take a number of years and after the induction of Bulgaria and Romania in 2007, Croatia is set to become a member of the EU in June 2013. Other countries like Turkey, Iceland, and the Western Balkans are in accession negotiations to follow suit. Membership generally offers great benefits to member countries, particularly those struggl ing to make the move from being developing nations to being developed ones. The European Union provides an economic and political support that smaller countries, or at least countries with smaller economies, can use to enhance their global standing, both within and outside Europe. But what is the impact that this expansion has, whether on the currently existing members of the European Union, the European Union as a whole, or even, in fact, Europe in general? Surely there must be certain economic and political impact such a membership must have, and economic advantage is generally gained at the expense of another party’s disadvantage. While that may be true, and in fact is to a certain point, it is not quite as limited as that. The results of many surveys, reports, and inquests have shown that the general perception among Europe’s public seems to be that membership offers great benefits to newer members while offering little to no benefit to older members. This percepti on might not be in the majority – with statistics varying from country to country – there is no doubt that it is a sizable portion of the public, any country or sample considered. Evidence supporting this matter is given further in the report, built generally upon information provided by the British Parliament in 2006. As negative as general perception might be, however, expansion has always shown to result in positive economic and political impact. This is true of any series of expansion, but this report will particularly center its focus on countries inducted in 2004, as they have had sufficient time to determine the effect of membership on their economy, as well as the impact of their membership on the European Union members in general. In fact, not only are the arguments brought forth against expansion generally baseless, with little evidence to support their claim, inverse evidence shows that economic arguments supporting the expansion of the European Union are la rgely misunderstood, or otherwise overlooked.

Vietnam and Singapore's Special Education Compared with that of the US Research Paper

Vietnam and Singapore's Special Education Compared with that of the US - Research Paper Example It is then noteworthy to look into the special education systems of these two countries and compare them with that of America’s. Regarding its history, Singapore’s SPED progressed irregularly. The major initiators were charitable organizations. As time passed, the government passed legislations and formed departments for proper facilitation. In 1947, Trafalgar Home was founded. It was for children with leprosy. In 1949, a center catering to crippled children was founded by the British Red Cross Society. By 1951, the same society also offered education for the deaf. After five years, a school was put up by the Association of the Blind. In 1957, there focus was given to those with cerebral palsy with the formation of Spastic Children’s Association. In 1962, the Singapore Association for Retarded Children (now known as Movement for the Intellectually Disabled of Singapore) was created. This association widened the horizon of special education by not only involving t hose with physical and sensory needs but those with intellectual disabilities as well (Tan, â€Å"Education in Singapore: Special Needs). Concerning its government, Singapore was colonized by Britain in 1819. However, during World War II, it was captured by the Japanese. In 1945, it was freed by British soldiers. In 1946, Singapore became a separate crown colony. On June 3, 1959, it was made a self-governing state in the Commonwealth of Nations. In 1963, it joined Malaya, North Borneo, and Sarawak to form Malaysia. After two years, Singapore separated from Malaysia and became a sovereign state as well as a member of the United Nations. In the same year (1965), it was proclaimed as a republic (â€Å"History of Singapore Colonization†). As for Vietnam, there are no distinct SPED- related organizations in its history. The education in Vietnam during feudal and colonial periods lacked stability leading to haphazard structures. Traditionally, it is a country built on Confucian-or iented education. However, it was replaced by French-Vietnamese education during its colonization at the end of 19th and first half of 20th centuries. This kind of education immobilized the rights of the Vietnamese since it was for the purposes of serving the colonizers. During their independence in 1945, their president, Ho Chi Minh advocated against illiteracy and formed an education system towards independence and rehabilitation. Within a year, there were 75,000 literacy classes and almost 96,000 teachers serving 2.5 million citizens. Since then the government maintained a public education. However, during the US air force attacks in 1965-1972, a number of schools were destroyed. Gradually, education was much influenced by North-American domination. In April 1975, Vietnam’s regions were reunited and they were able to achieve full independence. Several reforms were made concerning education. Included in the changes from 1986 to 2005 was the categorization of learning activi ties corresponding to students’ abilities. Specialized schools were established for gifted children (â€Å"Education in Vietnam: Development History, Challenges, Solutions† 2). The United States’ SPED history when it comes to its legislation is quite ample. These developments are also valuable since other countries are adapting these provisions. In the early 1900s, its education system offered compulsory education. However, many children with special needs were not welcome in numerous schools. Most of the rights of children

Mod13 Dyn Dis - Essay Example For example, hiring more employees during peak season may be necessary but hiring more during the low season of a business is irrational. If a change does not fit the current and future customers is may not be necessary. Any change done should match the corporate culture. Intended changes that do not match corporate culture may result in unintended consequences, and thus business leaders should avoid them. A business leader should ensure that the organization has the necessary resources to implement proposed changes (Langley et al., 2013). It may not be a beneficial idea to implement changes which the organization has no capacity to accommodate. Intended changes that do not have quantifiable value to the business are not appropriate. During the last holiday, I and my friends came up with a group whose mission was to clean up the local town twice a month. We hoped that this would motivate people to maintain the town cleanliness. All the members of the group were college and university students studying in different areas. Initially, the group looked superb but it ended up failing after we resumed school. There was no one to run the group, and it ended up being inactive. Our group failed due to lack of a good plan, lack of resources and lack of accurate speculation that are all needed for implementing changes. Langley, A., Smallman, C., Tsoukas, H., & Van De Ven, A.

Research Empirical Studies - Coursework Example 217-241). The sample data is taken from existing studies, in this case a study from the National Crime Panel that details the determination of available data from mapped an unmapped information sources in crime investigation settings. Such data is then factored into analyses of the effectiveness of law enforcement use of data and information to solve crimes. The thinking is that the more effective use of more information can lead to better law enforcement work as such work relates to crime investigations. The data analysis flows from this look into the availability of data and the degree of law enforcement use of such data (Skogan et al., 1979). The key threat to the validity of the research and its findings is that there is only one data source used, and that is a study that was done six years prior to the conduct of the research being described here. The reliance on one set of data limits the general applicability of research findings. This threat to validity is somehow addressed by the integrity of the institution that conducted that older study, and that the study was on a national scale, implying ample representation and ample population sizes (Skogan et al., 1979). Among the findings are that the status quo, where police leaned on data that they had at their disposal historically for particular crimes, yielded crime investigation outcomes that were far from ideal. On the other hand, the study also noted that there existed a larger amount of information from more sources, including bystanders and witnesses to crimes, than are being collected and used. The implication here is that with more rigorous ways of information collection, crime investigation outcomes would improve. The implications of the findings include that there needs to be a more rigorous attempt to gather data and to put up standard procedures

Periodontal Therapy Evaluation

Periodontal Therapy Evaluation Chapter One: Introduction The objectives of periodontal therapy as stated by the American Academy of Periodontology official guidelines are natural dentition preservation; periodontal health maintenance and improvement, comfort, esthetics, and function; and replacements provision where indicated. (Guidelines for periodontal therapy .J Periodontol 1998) Therefore, the reduction of bacterial deposits and calculus on tooth surface is one of the objectives of periodontal therapy. (Axelsson et al, 1991) This objective can be achieved with hand scalers and curettes or ultrasonic scaling instruments. (Drisko, 1998) Many clinical studies showed no difference between ultrasonic/sonic and manual procedures when treating chronic periodontitis. (Tunkel et al, 2002) Total removal of subgingival calculus with hand or ultrasonic instruments or even periodontal surgery is not possible even with periodontal surgery. (Buchanan et al., 1987; Kepic et al., 1990). While Aleo et al. (1974) demonstrated the presence of bacterial endotoxins on diseased roots; Hatfield Baumhammers (1971) first described the cytotoxic effect of diseased root surfaces in cell cultures. The former workers also detected that human gingival fibroblasts did not adhere in vitro to a root surface contaminated with LPS in 1975. Therefore, it was determined that the removal of the affected cementum was critical to the success of periodontal therapy. Nakib et al. (1982), however, in another in vitro study failed to demonstrate penetration of endotoxins into root cement of either periodontally healthy or diseased teeth. As a result, they considered intended excessive removal of cementum was not acceptable in treatment, which was reinforced by other workers findings. Also Eide et al. (1983, 1984) found that the thin cuticle seen on diseased root surfaces that was most likely stemmed from the inflammatory exudate and could mineralize so these cytotoxic substances can be incorporated. Hughes Smales (1986) and Hughes et al. (1988) also did not approve the removal of substantial amounts of cementum, as LPS was detected by immunohistochemical techniques only on the cementum surface. Interestingly, Moore et al. (1986) demonstrated that virtually all the LPS associated with periodontally involved root surfaces could be removed just by rinsing and brushing. The root cementum has been studied for the presence of endotoxins as well as bacteria themselves. Hence for example Daly et al. (1982) observed in a histological study stainable bacteria in the cementum. They have showed that for a root surface to be free of contamination, cementum must be removed. Bacteria were also detected by Adriaens et al. (1988) in both the cementum and within the dentinal tubules. These authors as a result suggested the administration of chemotherapeutics to mechanical therapy in the treatment of periodontitis was required. Schroeder Rateitschak-Pliiss (1983) sanctioned the findings of Daly et al. (1982) of resorption lacimae in the cementum showing defects of 30-80 /im in depth. Likewise they found that extensive root planing was essential to remove bacterial accumulation niches. From a clinical point of view the motive for the extensive removal of root surface material has been questioned recently. Nyman et al. (1986) disclosed in beagle dogs that for an effective treatment of periodontitis the removal of so-called diseased cementum was not needed. The roots, following flap elevation, were instrumented with curettes and a diamond bur on one side of the jaw and on the contralateral side were only cleaned with interdental rubber tips and rubber cups by means of a low abrasive polishing paste. The healing, which was assessed histometrically, was alike with both treatments and was distinguished by a junctional epithelium with subjacent non-inflamed connective tissue. Nyman et al. (1988) in a subsequent study in humans, compared results in which the root surface polishing was accompanied by calculus removal but not cementum and similar healing was again seen. Blomlof et al. (1987), in another investigation on monkeys, found new attachment to the teeth treated with detergents rather than scaling. The effects of root scaling in an in vitro model system (Lie Meyer 1977) have been studied using SEM methods and limited to semi-quantitative assessments with the Loss of Tooth Substance Index (LTSI) score. Others have tried to determine the loss of substance from the micrometer screw recordings in the light microscope, after focusing twice (Allen Rhoads 1963). The ultrasonic instrument, in a corresponding in vitro model, caused loss of tooth substance of about 250 pm and of about 50 /im after the curette use. Berkstein et al. (1987) measured the diameter of the dental root with a micrometer caliper before and after single treatment with the curette, detecting a loss of substance of about 27 pxn. The effectiveness of the procedures of root planing can be studied in two different ways. The first one, In vivo studies, by evaluating healing of tissues around the treated teeth, and the other one, in vitro studies, directly following extraction of teeth after SRP in order to observe the characteristics and cleanliness of the root planed surfaces (Kepic et al, 1990). The stereomicroscope has been used by many authors to assess the residual calculus after extraction of the root planed teeth. However, to achieve a precise study to accurately evaluate root planed surfaces, scanning electron microscope (SEM) is a prerequisite (Rateitschak-Plà ¼ss et al, 1992). Many studies, concerning both microbiological and clinical aspects, have reported beneficial results from mechanical therapy (O’ Leary et al 1986; Ash et al, 1964; Sbordone, 1990). The hand instruments, ever since, were the first choice of clinicians. These instruments believed to produce a smooth root surface; yet, considerable manual dexterity is essential for their effective operation. Also, they are so time consuming and do not have the capability of reaching deeper root surface where pockets are more than 4 mm deep (Waerhaug, 1978; Rabbani et al, 1981 ). Ultrasonic tips were formerly designed for gross scaling and supragingival calculus and stains removal. Currently, modifications have been made to these power driven instruments to have longer working lengths and smaller diameter tips, thus providing better access to deep probing sites and more effective subgingival instrumentation. Ultrasonic instruments are easy to use; yet, it is often challenging to achieve a smooth and calculus free root surface (Moskow, 1972; Jones, 1972). Studies assessing variations in the magnitude of root surface changes created by hand, sonic, and ultrasonic instruments are lacking (Walmsley et al, 2008; Oda et al, 2004; Kocher et al, 2002). Bearing in mind manual and ultrasonic scalers, some reports show that manual scalers remove more root substance (Jacobson et al, 1994), while others showed that ultrasonic scalers do so (Oda et al, 2004). Concurrently, roughness of root surface after instrumentation is one of the most described changes in the literature. The relationship between the design of the tip, applied force, angulations and ultrasonic scaler type has been reviewed and all of these variables appear to explain the roughness of instrumented root surfaces (Flemmig et al, 1998). Ribeiro et al (2006) revealed that scaling with universal ultrasonic tips and diamond-coated sonic produced similar root surface roughness, which was more than that produced by hand curettes. Furthermore, another study by (Casarin et al, 2006) showed a positive influence of the ultrasonic scaler power settings on the roughness of the surface after instrumentation. As reported by those authors, more increased roughness was noted with greater settings of power. Lie and Leknes (1985) assessed the variations produced at different power settings by means of a subjective and controversial method, the Roughness Loss of Tooth Substance Index (RLTSI). The RLTSI assesses roughness and substance loss concurrently. Nevertheless, the loss of tooth substance with the use of a specific instrument cannot be straightway correlated with the root surface roughness (Kocher, 2002; Schmidlin et al, 2001), requiring a separate evaluation (Schmidlin et al, 2001).

The Grapes of Wrath Analysis

The Grapes of Wrath Analysis The Grapes of Wrath, describes the difficulty of migrant labors during the Great Depression. Written by, John Steinbeck, this novel went on to receive many awards. Generally viewed as Steinbecks best and most striving novel, The Grapes of Wrath was published in 1939. Stating the story of an expelled Oklahoma family and their fight to form a reestablished life in California at the peak of the Great Depression, the book captures the sorrow and anguish of the land throughout this time-period. The bank forecloses on the Joads land, so they decide to move west in search of new jobs. Though the Joads travel west in expectations of creating a restored life, the American Dream avoids them, their journey to California proves to be sorrowful and disappointing. Though they find some comfort in a camp and eventually get jobs, the life they dream of has only slipped further away. The parallels between John Steinbecks life and the narrative story he carved are apparent and distinct. Steinbeck used imagery to paint a picture of current world situations that were going on in his life during the 1930s. His goal in writing this novel was to paint a picture and make his readers experience the life of the Dust Bowl immigrants. Though not a Dust Bowl immigrant himself, he spent a lot of time with them and got to know their anguish well. From the first chapters, to the unforgettable ending, The Grapes of Wrath remains a debated work in critical discussions, with themes and a setting that are uniquely American Beginning to write the novel in the mid to late 1930s, Steinbeck was surrounded by poverty, and hardship, and as are the Joads in the novel. Steinbeck modeled the setting to represent how things really were for migrant workers during this period. The Grapes of Wrath takes place during the Dust Bowl era of the 1930s. After being released from jail, protagonist, Tom Joad, quickly realizes that his familys farm has been repossessed by the bank. Tom finds the family at Uncle Johns home as they get ready for a long journey to California in search of work, a journey numerous desperate families are also taking. Route 66 provides the transportation by which the migrants will arrive to California. It is the path of a people in flight, refugees from dust and shrinking land, from the thunder of tractors and shrinking ownership,. from the floods that bring no richness to the land and steal what little richness is there (Steinbeck 118).In California, there was a Hooverville on the edge of every t own, where migrant individuals camp all together and care for one another (Steinbeck 234). The Joads experience the surroundings of a Hooverville when they cross the desert into California, There was no order in the camp; little gray tents, shacks, cars were scattered about at random (241). Steinbeck was inspired to write the novel after researching and producing a series of articles for the San Francisco News about migrant workers in California (Conder 248). Throughout the 1930s, due to drought and years of agriculture without crop rotation or other destruction prevention, severe dust storms blew away the lives of many in many areas of the central plains, which developed into what is known as the, Dust Bowl. Tied with the economic catastrophe of the Great Depression, this crisis forced thousands of people, many of them agriculturalists, off their property, wandering from place to place in hunt of work to survive. Several of these people, attracted by promises of opportunity, moved to California. Although they were from several states, the term Okie coined for a native of Oklahoma, one of the hardest-hit areas was attached to the waves of families desperately heading West, their few remaining possessions piled high on old, barely operating vehicles. Those who made it to California found little work, poor living conditions, a great deal of resentment and prejudice, and even violence directed against them.(The Grapes of Wrath) John Steinbeck formed a fictional plot using current realities of the Dust Bowl. The exposition begins when Tom gets out of jail for good behavior and he realizes that everything he left was now different and his family is absent as well. The conflict arises when, Tom is out on parole, and he strictly cannot leave Oklahoma. However, his family is planning to move to California, where a government program offers a beautiful future for emigrant sharecroppers. The entire family and Casy, a longtime family friend, fit into a small truck to travel across the country. The rising action occurs when, the Joads set off for California, where many others are migrating west. As the Joads drive on, they begin to hear rumors that there arent enough jobs in California. The climax is revealed when they arrive in California. As they go from place to place, searching for work, Casy, former reverend and current friend of Toms, leads a strike against the owners of Weedpatch, which in conclusion costs hi m his life. Tom spurs to lead the people, but the Joads must leave again when Tom thoughtlessly kills the corrupt policeman who murdered Casy. The falling action is seen when the Joads move onto a cotton-picking field where Tom hides out until his wounds are healed from the conflict. The resolution occurs when the Joads come to a farm where they find a barn. Inside the barn, they find a young boy and a man. They are sick from starving, and the man is not able to eat solid foods anymore without getting ill. Rose of Sharon gives the fading man her breast, which has milk from her recent birth, and comforts him with a blanket. They are all strangely at peace. The push for writing The Grapes of Wrath came out of John Steinbecks involvement of studying and publishing Harvest Gypsies, a seven-part San Francisco News series about the plight of agricultural migrant workers in California (Steinbecks Use). While leading that research, Steinbeck met and traveled with a man named Tom Collins, the manager of the Arvin Migrant Camp (informally known as Weedpatch Camp) (Steinbecks Use). The relationship Steinbeck formed with Collins grew between 1936 and 1938, when the two began traveling over the San Joaquin valley to gather information and offer aid to migrant families in crisis. He wrote about the Okie exodus by the seat of his pants, as it happened (OConnell 60). The Associated Farmers of California terminated the book as a pack of lies and communist propaganda' (The Grapes of Wrath). Steinbeck was put under surveillance of the FBI and received many death threats. The book was banned in many libraries and copies were burned in towns across The Un ited States (Conder 248). Steinbecks speech, is found in Tom Joad, the novels protagonist. ( McCarthy) Tom Joad is the novels protagonist .Joad is first seen coming home to Oklahoma after jail time for killing a man in a brawl, only to find an overcome land with local farms being repossessed by the banks. Tom and his family begin on their trek to California over highway 66. Tom Joad, Steinbecks figure of smoldering witness, the passive observer turned violent activist and communitarian conscience, has been grabbed by figures right and left to stand for something, represent something, or, in recent vintage, to represent nothing at all, rendered void of the political meaning deliberately invested in him by John Steinbeck (and others) (Simon and Deverell 181). Through Tom Joad, Steinbeck builds anger and a sense of injustice over the migrants misery. (McCarthy) Rose of Sharon is always watching out for the greatest interests of her unborn child and its seems to symbolize motherly instinct and protection. Steinbeck departs from strictly Biblical imagery in portraying Rose of Sharon as an earth mother. (Rombold 161). Her natural protective nature over her baby, makes it even more heartrending when it is delivered as a stillborn. By letting the stillborn child go upon the waters in its apple box, Uncle John inverts the story of baby Moses let go in a basket upon the Nile (Rombold 160). The symbolism of the earth mother is also a strong context within which to understand the final scene (Rombold 162). Steinbeck ends the novel by having Rose of Sharon nurse a dying man from her breast. Rose of Sharon loosened one side of the blanket and bared her breast. She looked up and across the barn, and her lips came together and smiled mysteriously (Steinbeck 455). A symbol of hope is understood through Rose of Sharons fostering actions in reviving the s tarving man. By ending the novel this way, Steinbeck continues his literary references to the Bible as it provides symbolic resurrection of humanity and steps towards societies regrowth ( Taliawaite). Jim Casy is an ex-preacher who knew the Joads as far back as Toms childhood, claims that he has totally given up preaching I aint preachin no more. (Steinbeck 20). Casy now places his faith in the astonishing power of human spirit. Steinbeck is representing Casey as a parallel to Jesus as his character carries optimism to the people that are in misery (Taliawaite). A more literal similarity that Steinbeck indicates to is his name, Jim Casey, which fatefully, has the same initials as Jesus Christ. I aint sayin Im like Jesus. But I got tired like Him, an I got mixed up like Him, an I went into the wilderness like Him. (Steinbeck 81). Although he still did not believe himself to be a preacher, he had the courage to stand up to the corruption and the unfairness. Casey planned on leading the people in a strike that would help the laborers attain reasonable wages however he gets murdered during the objection. The preacher, ony he was a-leadin the strike. They come for him. They killed im . Busted his head (Steinbeck 390). Like Jesus who sacrificed himself on the cross, Caseys death is a sacrifice for the wellbeing of others. Caseys last words were You don know what youre a-doin (Steinbeck 386) which can be paralleled to Jesus last words. Father, forgive them; for they know not what they do (Luke 23:24) (Rombold 157). Casey dies with honor and self-respect, as Jesus did. John Steinbeck says that in growing up he absorbed the Bible through his skin (Rombold 146). Characters from the book mimic real life people suffering through the Depression. They had a reason to believe that there was a higher power watching over them during this time of hardship (Rombold 146). While Steinbeck used Biblical references, he chooses to keep God as an absent character, For Steinbeck, the people themselves are the agents of change and the parties responsible for action. His use of Biblical allusions which generalize and deepen the Joads experience within the tradition of the mythos, place this novel within a very broad context. (Rombold 147). Readers were shocked by the notion of neglecting God, but they had to consider the source, and learned to accept that it was Steinbecks (Rombold146). Land and place are so more than just passive settings in The Grapes of Wrath. A mans connection to land is a very important theme, Mans love of the land, his need not so much to own it as to embrace it, to sink his hands and feet in it, to cry for joy when the corn is peeking through and to sleep like a dead man when the last load is in the silo- this is the strongest force in the book (OConnell 59). Despite the ruggedness of the landscape, it develops the backdrop in contradiction of a wide range of human concern. Famers and country men had a very strong relationship to the property they grew to know. When they lose their land, the Joads not only lose their means of support, but they also lose their home. California is supposed to be a land flowing with milk and honey, a place of chance and change(McCarthy). For a farmer, land is opportunity, and therefore land is money. The Grapes of Wrath, Steinbeck endorses the philosophy that economic, legal, religious, and societal forces large ly control individual destiny, but lays out a philosophy to rise above those forces and achieve personal freedom (Conder 260). The American dream is unattainable to immigrants. In The Grapes of Wrath, Steinbeck often challenges whether or not California is the, promise land. He questioned if the whole thing of life, liberty, and the pursuit of happiness are achievable. For so many, the American Dream is a capitalist dream. Instead, Steinbeck, through his characters and themes, sought the dream of unity and compassion. Through Jim Casy and Tom Joad, it is seen that their passion lays in standing up for what is right, rather than sitting back and taking the hit. But that wasnt always the case for them, towards the beginning of the novel, all of them were eager to reach this so called, promise land. But eventually, they came to the realization that they were indeed just chasing an unrealistic dream. The Joad family is leading down something of a problematic golden road- a path of escape from destitution to an ambiguous Californian deliverance. when the only option becomes putting the family on the road to a str ange and unknown destination, problems are compounded (Spangler). The Joads persistent letdown to find supportive work and pay led to economic decay, lessening the likelihood that the American Dream would come to completion. Arthur G. Neal stated, [the] economic hardships after the Great Depression fell disproportionately on the family unit (Spangler). Throughout all the economic struggle and failures on finding the American Dream, the Joads managed to stick together through the triumph. John Steinbeck emphasized the theme of the unattainable American Dream; however, he added in that maybe people can achieve their own dream just by sticking together and never giving up. From the Joad family leaving Oklahoma, to the struggles in California, The Grapes of Wrath remains a moving and an extremely well written piece of art. The plot, setting, and characters are very expressive, and Steinbecks fascinating writing techniques give the themes of the book a distinct feel. The parallels between John Steinbecks life and the narrative story he carved are apparent and distinct. Throughout the 1930s, real people with real problems faced issues like what the Joad faced. John Steinbeck wrote a brilliant piece work in expressing the economic and emotional anguish the Oakies experienced. Chronology February 27,1902- John Steinbeck was born in Salinas, California.

Genetics and the Future :: Science Biology Genes Essays Papers

Rows upon rows of â€Å"perfect† people walk in straight lines. All have the same hair, eye, and skin color. They all resemble each other. The environment around them is lifeless; the lack of trees and living animals is awkwardly noticeable. Overhead a flying automobile soars past and swerves around enormous skyscrapers. All this was accomplished through both science and technology. Is this a farfetched notion of the future? Can science and technology really create a society like this? How will it affect our lives here in the Valley and in the world around us? Science has always been with us. Science is the observation of the problems of the world around us, and the experimentation to find solutions to these problems. It was science that allowed primitive man to wonder about his origins, his creator and the world around him. If we look at the role of science in the human race we see that it has allowed for the unified progression of all. In the beginning primitive ma n relied heavily on personal beliefs of both good and bad spirits and that of a Supreme Being. Later beliefs became more complex and religion was a vital part of everyone’s life. The ability to think differently grew due to increase advancement in science and technology during the Renaissance period. The freedom of thought and proposal of ideas by philosophers provided for exchanging and creation of diverse ideas. It was in that type of environment that ideas such as that of Darwin’s Origins of Species were proposed. In modern times when people hear of genetics images of cars overturned by dinosaurs gone mad, from the famous motion picture Jurassic Park, and of the cloned sheep Dolly prancing around in the prairie come to mind. The genetic revolution in particular gives us all an optimistic future to the world in which we are living in today. The genetic revolution will give a different facet to medicine, agriculture, and society as a whole. The genetic revolution will help health professionals provide a different type of care for their patients. The genetic revolution offers enormous promises for those sufferings chronic diseases. Research laboratories around the world are busily sequencing, identifying, and switching genes among different species. Genetic engineering techniques promise cures for various diseases such as cystic fibrosis and kidney disease.

1984 And The Left Hand Of Darkness Essay -- essays research papers

The two books Nineteen Eighty-Four and The Left Hand of Darkness help to define humanity and truth. Humanity is the condition, quality or fact of being human collectively. The definition of truth is things as they are, things as they have been, and things as they are to come. Truth cannot change because it does not reflect a personal perspective. These books illustrate how humans relate towards themselves, friends, enemies and humanity as a whole. Truth allows humans to stand-alone. When they find truth they are able to be one against the whole. "Being in a minority even a minority of one did not make you mad. There was truth and there was untruth, and if you clung to the truth even against the whole world, you were not mad."(Pg.171, Nineteen Eighty-Four) This fact allows Winston to fight against the party. Truth is a powerful weapon that can defeat all odds. "One voice speaking truth is greater force than fleets and armies, given time." (Pg. 27, The Left Hand of Darkness) Genly Ai knew that eventually the people of Winter would accept the truth, however it would only take time. Truth cannot be changed by man but can only be distorted. This fact is illustrated in both books. "The shortcomings are in the messenger, not the message." (Pg. 106, The Left Hand of Darkness) Genly Ai knew that sometimes when the responsibility of the truth is on one person it could get distorted. The truth can also get distorted when the people holding the power are in charge of keeping the truth. "Everything faded into mist. The past was erased, the erasure was forgotten, the lie became the truth." (Pg. 62, Nineteen Eighty-Four) When truth is distorted one loses the freedom to decide if one wants to support truth or untruth. When people's friendships go untested they believe a friend would do anything for them, but when the trials come the trials end in betrayal. Winston believes he will stay true to Julia no matter what happens. "If I could save Julia by doubting my own pain, would I do it? Yes, I would." (Pg. 184, Nineteen Eighty-Four) After Winston betrays everyone except Julia, he still believes he can withstand his torture and not betray Julia. "You have whimpered for mercy, you have betrayed everybody and everything. Can you think of a single degradation that has not happened to you? Winston had stopped weeping, th... ...ston is a part of his country by force, he eventually is brain washed by O'Brien and changes his hate for Big Brother to love for him. "Down with Big Brother!" (Pg. 18, Nineteen Eighty-Four) "He loved Big Brother." (Pg. 236, Nineteen Eighty-Four) He loses his freedom for he feels that freedom is the ability to die hating Big Brother. "To die hating them, that was freedom." (Pg. 223, Nineteen Eighty-Four) Winston is brain washed and as a result he loses the freedom to make his own decisions about whom he will hate and whom he will love. These books show that though the relationships between humans might be different, the principals are the same. These principals include the fact that humans will stand-alone when they have the truth on their side because truth cannot be changed. Secondly, when friendships are tried, they will break because of one's love of him self. Moreover, the death sentence is not a necessary way to punish one's enemies. Lastly, being part of a group can be helpful because an individual belongs, yet harmful because of blind loyalty. The relationships people build with others are a reflection of their beliefs of truth and humanity.
