Biography of Tarquin the Proud, Etruscan King of Rome

Biography of Tarquin the Proud, Etruscan King of Rome Lucius Tarquinius Superbus (died 495 BCE), or Tarquin the Proud, ruled Rome between 534 and 510 BCE and was the last king the Romans would tolerate. Tarquinius despotic reign earned him the title Superbus (proud, haughty). The flaw in Superbus character- he combined a great deal of ambition with a wealth of family treachery in his background- eventually led to the end of the Etruscan rule over the city of Rome. Superbus was a member of the Tarquin Dynasty, dubbed the Great House of Tarquin by Romes historian Livy, but the spotty, intrigue-riddled reign was hardly a dynasty. The Tarquins were one of several Etruscan chiefs, including the Tarchu, Mastarna, and Porsenna, who in turn usurped Romes throne with little chance to found genuine dynasties. Cicero sketched the Tarquin history in his Republica  as an example of how easily good government could degenerate. Fast Facts: Lucius Tarquinius Superbus Known For: The Last Etruscan king in RomeAlso Known As: Tarquin the ProudBorn: Year unknown in RomeFather: Lucius Tarquinius PriscusDied: 495 BCE in Cumae, RomeSpouse(s): Tullia Major, Tullia MinorChildren: Titus,  Arruns, Sextus, Tarquinia Early Years Superbus was the son or possibly the grandson of Tarquinius Priscus and son-in-law of the previous Etruscan king Servius Tullius. The exact date of Superbus birth is unknown. Ciceros text suggests that Superbus and his future wife Tullia Minor killed their respective spouses, Arruns Tarquin and Tullia Major, before murdering Servius Tullius and bringing Superbus to power. There are no historical records for this period in Roman history: Those records were destroyed when Gaul sacked Rome in 390 BCE. What scholars know of the Tarquin history are legends written down by the much later Roman historians Livy, Cicero, and Dionysius. Superbus Reign After ascending the throne, Superbus embarked on a campaign of expansion early in his reign, waging war against the Etruscans, Volci, and Latins. His victories helped cement Rome’s status as an important power in the region. Superbus also signed Rome’s first treaty with Carthage and completed construction of the massive Temple of Capitoline Jupiter. He also used forced labor to extend the Maxima drainage system, an important water-and-sewer system in ancient Rome. Revolt and the New Republic A revolt against the corrupt Etruscans was spearheaded by Tarquin the Prouds nephew Lucius Junius Brutus and Lucretias husband Tarquinius Collatinus. In the end, Superbus and all of his family (ironically, including Collatinus) were expelled from Rome. Along with the end of the Etruscan kings of Rome, the power of the Etruscans over Latium weakened. Rome replaced the Etruscan rulers with a Republic. Although there are some who believe there was a gradual transition to the consul system of the Republic, the Fasti Consulares list the annual consuls straight after the end of the regal period. Legacy Classical scholar Agnes Michels and others have suggested that the text Livy, Dionysius, and Cicero used to describe the events of the Tarquin Dynasty has all the earmarks of a classic tragedy, or rather, a trilogy of plays with the moral theme of cupido regni (kingdom of lust). Superbus legacy of court intrigue and scandal led to the end of the Etruscan rule of Rome. It was Tarquin the Prouds son, Tarquinius Sextus, who raped the Roman noblewoman Lucretia. Lucretia was the wife of his cousin Tarquinius Collatinus, and her rape brought about the end of Etruscan rule. Lucretias rape was scandalous on several levels, but it came about because of a drinking party during which her husband and other Tarquins argued over who had the most beautiful wife. Sextus was at that party and, aroused by the discussion, came to the virtuous Lucretias bed and forcibly raped her. She called her family to demand revenge, and when they didnt deliver, she committed suicide. Sources Gantz TN. 1975. The Tarquin Dynasty.

Double-Helix Structure of DNA

Double-Helix Structure of DNA In biology, double helix is a term used to describe the structure of DNA. A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is a nucleic acid composed of nitrogenous bases (adenine, cytosine, guanine, and thymine), a five-carbon sugar (deoxyribose), and  phosphate molecules. The nucleotide bases of DNA represent the stair steps of the staircase, and the deoxyribose and phosphate molecules form the sides of the staircase. Why Is DNA Twisted? DNA is coiled into chromosomes and tightly packed in the nucleus of our cells. The twisting aspect of DNA is a result of interactions between the molecules that make up DNA and water. The nitrogenous bases that comprise the steps of the twisted staircase are held together by hydrogen bonds. Adenine is bonded with thymine (A-T) and guanine pairs with cytosine (G-C). These nitrogenous bases are hydrophobic, meaning that they lack an affinity for water. Since the cell cytoplasm and cytosol contain water-based liquids, the nitrogenous bases want to avoid contact with cell fluids. The sugar and phosphate molecules that form the sugar-phosphate backbone of the molecule are hydrophilic, which means they are water-loving and have an affinity for water. DNA is arranged such that the phosphate and the sugar backbone are on the outside and in contact with fluid, while the nitrogenous bases are in the inner portion of the molecule. In order to further prevent the nitrogenous bases from coming into contact with cell fluid, the molecule twists to reduce space between the nitrogenous bases and the phosphate and sugar strands. The fact that the two DNA strands that form the double helix are anti-parallel helps to twist the molecule as well. Anti-parallel means that the DNA strands run in opposite directions, ensuring that the strands fit tightly together. This reduces the potential for fluid to seep between the bases. DNA Replication and Protein Synthesis The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. In DNA replication, the double helix unwinds and each separated strand is used to synthesize a new strand. As the new strands form, bases are paired together until two double-helix DNA molecules are formed from a single double-helix DNA molecule. DNA replication is required for the processes of mitosis and meiosis to occur. In protein synthesis, the DNA molecule is transcribed to produce an RNA version of the DNA code known as messenger RNA (mRNA). The messenger RNA molecule is then translated to produce proteins. In order for DNA transcription to take place, the DNA double helix must unwind and allow an enzyme called RNA polymerase to transcribe the DNA. RNA is also a nucleic acid but contains the base uracil instead of thymine. In transcription, guanine pairs with cytosine and adenine pairs with uracil to form the RNA transcript. After transcription, the DNA closes and twists back to its original state. DNA Structure Discovery Dr. Francis Crick and dr. James Watson at a molecular biology symposium. Ted Spiegel  / Contributor  / Getty Images Credit for the discovery of the double-helical structure of DNA has been given to James Watson and Francis Crick, awarded a Nobel Prize for their work. Determining the structure of DNA was based in part on the work of many other scientists, including Rosalind Franklin. Franklin and Maurice Wilkins used X-ray diffraction to ascertain clues about the structure of DNA. The X-ray diffraction photo of DNA taken by Franklin, named photograph 51, showed that DNA crystals form an X shape on X-ray film. Molecules with a helical shape have this type of X-shape pattern. Using evidence from Franklins X-ray diffraction study, Watson and Crick revised their earlier proposed triple-helix DNA model to a double-helix model for DNA. Evidence discovered by biochemist Erwin Chargoff helped Watson and Crick discover base-pairing in DNA. Chargoff demonstrated that the concentrations of adenine in DNA are equal to that of thymine, and concentrations of cytosine are equal to guanine. With this information, Watson and Crick were able to determine that the bonding of adenine to thymine (A-T) and cytosine to guanine (C-G) form the steps of the twisted-staircase shape of DNA. The sugar-phosphate backbone forms the sides of the staircase. Source: The Discovery of the Molecular Structure of DNA- The Double Helix.

Participation Questions Week 2 Essay Example | Topics and Well Written Essays - 750 words

Participation Questions Week 2 - Essay Example Why are companies interested in operational management today? Why is it important? What is the relationship between operational management and supply chain management? How are operations management functions performed at your organization? Companies are interested in operational management today because of how important it is to get daily work done efficiently, timely, accurately and at a low cost. It is necessary to ensure that the processes of creating a product actually works right and that improvements are made in customer service that can lead to cost reductions. Because every organization produces some product or service, an understating of modern or up-to-date approaches to managing operations is a good idea. In the past, manufacturing businesses showed more interest in the use of operations strategies and operations management but a business that offers a service can better offer that service in a more efficient manner if it treated the actual customer service as a product. According to the week one course overview, operations management refers to the direction and control of the processes that turn inputs into finished products or services and supply chain is the link between the suppliers of the material and services that convert throughout the process, the ideas and raw materials into the finished product. I work at a college and the operations management functions has so many levels. Because I work in the College of Continuing Studies, it is easy to see how the process for this particular level works. Most offices perform meeting and follow-up meetings that may be an expression of ideas that could possibly turn into a process. The follow-up meetings with expected target dates and action items seem to be the best way to ensure that the meetings have not just been a waste of time. I agree with your view that companies today are interested in operational management today

Child abuse Essay Example | Topics and Well Written Essays - 750 words - 1

Child abuse - Essay Example Taking a moment to know and understand some of these causes will help us to find ways of preventing child abuse. Some children have been found that they were abused by parents who had unexpected pregnancies and therefore resulted to unwanted children who end up being neglected and develop a very poor relationship with their biological mother or both parents. The parents who also physically beat their spouses are known to extend the same frustrations on their children. People who take drugs like alcoholic drinks and cigarettes or cocaine also have a tendency in abusing children. Other factors are unemployment and financial difficulties which are associated with increased rates of child abuse (Check, 1989). In a 2009 CBS News report, it was realized that child abuse in the US had become greater during the economic depression. An example was given of a father who was not a sole breadwinner . But when the father was in that role, the situation changed. In this discussion, I will talk about two factors, these two factors are; Alcoholic parents and Parents experience of violence. The problem is drinker parents and parent’s history of abusing by their family members are the most important reasons that lead parents to abuse their children. It is very important to prevent violence toward children. How do we prevent this issue? We have to stop and limit this concern by knowing the exact problem in terms of the effects it has on the children and then by addressing the solution. According to the studies from World Bank and World Health organization, â€Å"alcohol-related death and its impact is bad. The dangerous effects of alcohol use on health and the likelihood of becoming an addict have been recognized as dangerous issues of great concern for a long time (www.searo.who.int). Parents who drink alcohol or any other substances that cause them to get drunk will often abuse their children if the level of their drinking is too much. Drinking

Social impact of ICT Essay Example for Free

Social impact of ICT Essay Industries food reduce the need for human labour. 1. e. cow, milk and bucket. When cheese gets in great demand, cant milk cows myself, so get more people. But still cant keeps up! Cant mechanise cow but can the milking! Now need admin dept to manage staff!! Paper base system to collate all orders. But now big company need technology. Man who builds machine needs more men to build more machines. Etc. Technology has both positive and negative effect. 1000s of jobs have gone because of computers. The rapid advances in computer and communication technologies have occurred during periods of considerable change in industrialized economies and although many different factors have conspired towards the generally higher levels of unemployment ICT has undoubtedly played a major role in creating new industries and jobs in general, introduction into it systems in organizations may result in: A need for staff retraining; redeployment; deskilling; regrading; redundancy; changes in job satisfaction; new job opportunities; remote/tele working; changes in career prospects. An old fashioned secretarial job required typing skills, note taking skills, filing skills, and document organizational skills. Most managers now act as their own secretary, the manager has been reskilled and she has been made redundant. There is an argument, which suggests that traditional industrial relations will have little place in the workplace of tomorrow. As we move towards the information age, the old models of labour relations with all the assembled baggage of collective bargaining between employers and workers representative bodies will become increasingly inappropriate to the new realities of work. According to this point of view, the very term industrial relations is itself a giveaway. It harks back to the industrial age, the time when the growth of large-scale production in hierarchically structured organisations led to a need for the collective regulation of employment relationships. The development of trade union organisations, for example, was predicated upon the existence of the factory system, bringing large numbers of workers together in a central workplace. What if this is no longer the way in which work is organised? What if new technologies permit a new flexibility in the way work is undertaken? For much of the twentieth century, industrial relations focused on what was seen as the normative way of working. The paradigm has been that of a full-time worker (or indeed man, since historically the assumption was that the male was the main bread-winner), working under an employment contract for one employer and remaining with their company for many years or until the time came to draw the company pension. This paradigm further was based on a clear separation between work and home spheres of life, between the hours of work and the hours of non-work and indeed also between a persons years of working and their abrupt transition into retirement. It is possible to discuss the extent to which this paradigm ever adequately reflected working life the critique has been advanced that it left out of the picture the work undertaken by women, particularly part-time and casual employment, for example. It also ignored working realities in most of the developing world. But nevertheless for most of the developed countries, this paradigm provided a basis not only for the structuring of industrial relations but also for social protection systems and retirement pension arrangements. The argument now is that, in any case, this paradigm fails to be appropriate for a network economy where value comes from the manipulation of information and knowledge much more than from the production of material goods. In the process of change, a job is becoming redefined simply as work. ATTs vice president for human resources James Meadows put it this way, in a quote attributed to him in the New York Times: People need to look at themselves as self-employed, as vendors who come to this company to sell their skills. In ATT we have to promote the concept of the whole work force being contingent, though most of our contingent workers are inside our walls. Jobs are being replaced by projects and fields of work, giving rise to a society that is increasingly jobless but not workless. 1 Many writers have engaged with this subject. Research on the growth of flexible working practices undertaken for the OECD identified a number of developments, including changes in the design of jobs, greater complexity, higher skill levels, greater use of team working and also increased delegation of responsibility to lower levels of staff. 2 Ulrich Klotz, from the German trade union IG Metall, has described changes in work organisation thus: Work is splintering into many forms As the new company models proliferate, forms of work are spreading that we still refer to as atypical: part-time work, temporary work, limited contracts, telework, contract work and other forms of (pseudo) entrepreneurial work In short, work is still with us but the stable job is not. He warns that as a consequence trade unions are in danger of losing their traditional business base. 3 ICT permits both the spatial and temporal relocation of work, challenging the idea of a discrete workplace and a discrete working day. However it would be wrong, of course, to see changes in work organisation as simply the result of technology. These changes are being driven by a number of factors. We can identify trends in management practice, including such things as the outsourcing of non-core activities and the reengineering of business processes as also contributing to workplace transformation. However, these developments are closely intertwined with developments in ICT. In an early essay, Manuel Castells suggested that there are two overarching inter-related processes at work, driving change in the workplace: the technological revolution based on microelectronics is one of these, the growing interdependence of the economic system globalisation is the other. 4 In terms of labour relations what all these changes mean, effectively, is a new implied contract between a company and a worker. The old employer/employee relationship, which offered security and reward to the individual in exchange for corporate loyalty is to go. Instead, individuals are told to take responsibility for their own working life and career, including the responsibility of ensuring that they constantly update their skills. In exchange a company undertakes to empower them in their work, by removing old-style supervisory practices and replacing these by new types of team working, based on performance management. The old master/servant basis to the employment relationship, in other words, is replaced with something more, well, modern. This sounds a seductive idea, though it blows a gaping hole in the way in which industrial relations, institutionalised in the relationship between employers representative bodies and trade unions, have traditionally been conducted. If correct, it would inevitably lead also to major changes in social and welfare protection and employment law. In the process, it would also leave todays trade union bodies cast up and redundant, rather in the way that antique steam engines, previously employed huffing and puffing their way through their working day, were left silent and fit only for scrap with the arrival of electricity. The question explored by this chapter is whether, and if so to what extent, the argument for the end of traditional industrial relations is justified. We will begin by exploring further the challenges which face the social partners, considering how the services they currently offer could be provided in other ways by other agencies. We will then investigate the state of industrial relations in one particular sector which has encountered radical change in recent years, the telecommunications industry, to see what evidence for a paradigmatic shift can be found there. We will move on to consider in some detail two examples of new work organisation (call centre working and telework) and two areas where atypical working has been growing (agency work and self-employment), to ask whether these are or are not being adequately accommodated within organised industrial relations. We will then turn to consider the degree to which the traditional industrial relations negotiating agenda has been extended by ICT. This will take us into a number of areas, including on-line rights for workers, questions of privacy and electronic surveillance and the increased relevance of copyright and intellectual property rights. We shall look at examples of how the social partners, and in particular the trade unions, are themselves making use of ICT opportunities. Finally, at the end of this journey, we shall return to the issue posed at the start of this chapter, hopefully in a better position to offer some conclusions.

Spirituality and Edna St. Vincent Millays Works Essay -- Edna St. Vin

The assimilation of human feeling with nature impacted the writings of Edna St. Vincent Millay throughout the entirety of her career. At an early age, on the coast of Maine, Millay had a quasi-religious experience while nearly drowning, that when written down ten years later became the foundation of one of her most staggering works, â€Å"Renascence.† The way in which Millay confronts and interacts with nature, namely the sky, is unnerving, raw, and beautiful. She transcends time and is enabled to take part in an empathetic experience with the entirety of what she perceives around her. This poem serves as a precursor to later poems that deal with the human and its counterpart in existence, nature. Over the course of her work, Millay was constantly reconfiguring her notion of God, humanity, and nature and how they were interrelated. This examination and understanding of a oneness with things is the theme found throughout her writing. In addition to â€Å"Renascence†, it is found in â€Å"Spring† as well as â€Å"Epitaph for the Race of Man.† The constant it seems is her communion with that around her in the natural world. Her offerings of interpretations and meditations on the earthly goods of nature and humanity showcase a pantheistic view of the world, in which everything equals God. The poem â€Å"Renascence†, which garnered Edna St. Vincent Millay instant fame as a poet and allowed her entry into her life as a writer was written when she was only eighteen, ten years after a near drowning incident off of coastal Maine. The poem deals with the spiritual experience of accepting man’s suffering and offers an extended and meditative view of nature as a presence that pushes and awakens the sense of empathy in man. The beauty of â€Å"Renas... ...even if these connections are made by the shared experience of death. It is in this connection to larger ideas and showing then, the connections to smaller entities therein, that Edna Millay is able to project a pantheistic sensibility, even if this is in the minor chord of foreboding destruction. The humanity that Millay is privy to in the understandings she obtains from the observation of earth, sky, season, and the cycle of existence is the paramount essence of her writing. The poetry of Edna St. Vincent Millay is the poetry of evaluation of that which is shared and experienced. In each of her writings above, Millay has reconfigured the notion of nature and humanity, not as separate things existing in the same world, but rather two forces occupying each other’s space long enough that there is an indelible reference to each in the existence of the other.

Starbucks Going Global

â€Å"Starbucks – Going Global Fast. † I. Saturation of Home market and existence of Foreign Untapped markets Starbucks is a well respected brand of coffee that is known globally. As they dominate the market in United States, they have realized the potential growth in overseas markets and open its doors to going global. However, competing internationally is not easy for every company that’s why Starbucks has encountered certain challenges and issues as it enters foreign markets and grows globally. II. Problems Major Problems: Employee DiscontentEmployee discontent is very far from the image that Starbucks obtains or would like to uphold. Dissatisfied employees could greatly affect the service that they provide to the customers. The company is focused on enthusiastic, happy baristas and friendly service. If employee morale dropped it could have an extremely negative effect on Starbucks’ image and sales as well. As stated in the case, 470 California stores s ued Starbucks for refusing to pay legally mandated overtime pay. This is due to overworked and underappreciated workers. The salary Starbucks provide doesn’t match the workload that is required by the company.The employees, especially the store managers feel exhausted and employee morale goes down. The employees are feeling less connected with the company mission and it affects the quality of service and products that they provide. Local challenges in Foreign Market Entry The influence of economic and political environment to its entry and operation in foreign countries is one of the challenges it faces. As Starbucks continue to open up stores in foreign markets, it also faces different challenges as local imitators try to steal market share.In Japan, they expect loss for the full year. Aside from local competitors offering products with the same price, the economic depression in Japan affected the customer’s income and buying behaviour. As a result the company is losi ng rather than gaining profit due to coffee pricing. In addition to political environment, Starbucks need to adapt into France’s regulations and generous labour benefits which is legal and compulsory for them to enter the market. Another problem is the entry to foreign markets that has strong local coffee culture.The company is still in its stage of assessing the right strategy to enter markets like Italy. Since it is struggling on its food and non food items, the competition in this market will be difficult due to the existence of anti-globalization movement and strong national responsiveness of local consumers to its own products. Minor Problems: Specified Target Audience Starbucks used the â€Å"Youth appeal† as a strategy to enter foreign markets and gained success, but in the home market attracting the next generation of customers seems to be an issue.The result of the market study made the company aware about the image that it has with its target customers. Young er coffee drinkers can’t afford to buy coffee at Starbucks or the reason they go there is not mainly because of coffee or its products but their peers working. The value associated with brand at some point doesn’t convince the young people in embracing the brand itself. It depicts a pretentious environment for social climbers or yuppies. Aside from trying to reach a specific target market, the company eventually ended up in different markets as it grows rapidly.Venture to Food and Non food items To keep up with competition and increase sales, Starbucks should not solely rely on coffee as its main product but other products they can take advantage of as well. As Starbucks wants to continually increase sales, it started offering food and other non food items to sell inside their stores during the late 90’s but it seems to be a challenge because it still struggles in this area. The company started offering sandwiches and desserts, CD’s and packaged coffees b ut growth rate doesn’t seem to rise.The company still has to work on the right approach as it continues to improve in this area. III. Solutions: A. Employee Discontent Employees are very important in the success of any company. They are considered as the first customer in every business. Satisfying employee needs is essential so that the company can achieve its goals and deliver proper service. Starbucks needs to be sensitive to their employee needs. They must equally match the compensation to the workload of the employees. Since the company is also going global, there are challenges in human resource that they need to focus on.They have to be aware of the employees’ local culture and needs to satisfy them. They should also conduct a survey internally to be aware about the employees’ needs, wants and feelings towards the company. This will help them properly design employee compensation and benefits. There will be adaptation towards the company’s approach in managing employees in overseas branches. They should take into consideration the legal environment of each local branch so that they can address specific needs and concerns as they manage the business across different cultures.Happy and satisfied employees will result to quality in service and products. B. Local Challenges in Foreign Market Entry Starbucks should conduct marketing research and environmental scanning as it enters foreign markets. They have to take into account the importance of economic and political environment and how it can greatly influence the operation of its business. They should be aware of the economic situation of the market and assess how it can affect the purchasing power of the market. They must be aware of the legal factors that would affect the way it operates its business overseas.They should also conduct a different marketing strategy for different markets since one strategy in one market will not guarantee the success in another. There will be a daptation in marketing approach and local operations to cope up with the foreign market’s needs and external environment. C. Specific Target Audience Since the company intended to reach a specific target market, it ended up catering to different markets as it grows rapidly. As they continually use the â€Å"Youth Appeal† because it gained success as they enter foreign markets, it cannot still be considered as a global strategy to enter the market to other countries.Starbucks should make a study about coffee culture before it enters the market and formulate a strategy that would simply meet the demands of the potential market. They should carefully position the brand in accordance to what they want the market to perceive. As with the case of Starbucks to its home market, the brand was associated with being pretentious. They should associate positive and sophisticated value with the brand. D. Venture to Food and Non Food Items Limitation to product choices restricted the business growth of Starbucks and there is a tendency that customers might get bored and switch to other others.As Starbucks is going abroad they should not focus only to their core products but also find ways on how to improve the quality of their coffee, the services and their environment. This will be very helpful especially if they want to capture the market in France and Italy. They can also venture into bringing some new products especially food and non food items to its menu that would help fulfil the current and local demand of the market. IV. Recommendations A. Employee Discontent * Employee Survey Starbucks needs to conduct an internal employee survey to know the needs of their employees and what makes them content.They should also initiate personality test to all employees especially with their branches abroad. This may be costly but if the results will be interpreted in the right way then the company could address the needs of the employees. This will also help them mana ge human resource despite the difference in culture and will help them appropriately design compensation and benefits to the employees. * Corporate Communication of Company Vision and Mission Since the employees feel less connected with company mission, Starbucks should promote awareness within the employees about the company’s Vision and Mission.This will make the value the corporate values set by the company. The importance of achieving the company Vision as it delivers quality service and product. This will make them brand hearted and will have this sense of connection with the mission of the company. B. Local challenges to Foreign Market Entry * In-depth Marketing Research and Environmental Scanning The company should be knowledgeable to all the factors in Macro and Micro Environment that could affect, influence and help them in their business operations. The company should always be updated with the data so that they could be prepared with the changes that may happen. Do mestically designed Marketing Mix To avoid the errors to Ethnocentrism, the company should adapt to local cultures and needs of their foreign market. They should be able to use the approach as they communicate with their customers while implementing their market strategies. As for the case in France and Italy, the company should also create products that would suite the local taste of the market and recognize the market’s own unique culture. C. Specified Target Audience * Marketing Research Starbucks should be able to properly address the demands of the local market they have in various countries.The company should not only focus one approach as it enters foreign markets. In some countries, â€Å"Youth appeal† worked, but in other countries the target market of Starbucks are adults. They have to sensitive with the target market that they serve in every country because for some Starbucks is unaffordable and pretentious. They should know more about what attracts the loca l market, purchasing power, buying behaviour. In other countries, pricing is not a barrier but they are more on value, ambience and status. Others are more on practicality and benefits. D.Venture to Food and Non Food Items * Adaptation to local culture, demands and tastes Starbucks should introduce new products either food or non food items that would cater to the local demands of the market. They should blend with the local taste of the market. They could also recognize the culture of the market and include it on its menu. One example is in Italy, they could launch one product like a local espresso as part of the menu so that local customers would feel that it’s not just an American coffee, Starbucks are also sensitive to their local taste.

Research Paper on Fast Food Essay

1. 1 INTRODUCTION Fast food is generally food or a meal which is pre-prepared, or which can be quickly cooked when you order it. You can buy fast food almost anywhere. Although fast food trend is quite new in Pakistan yet it is growing very fast, this indicate that such type of fast food restaurant have a very bright future in Pakistan . The two major fast food restaurants that have their outlets in the whole world, are giving tough competition to each other in Pakistan. Our research is based on the hypothesis that why people in Pakistan prefer KFC over Macdonald and we found that due to good quality and taste of food people prefer KFC . When KFC was introduced in Pakistan the prices was not affordable by people but now they have lower their prices. One reason was also the impressive packages due to which people prefer KFC over McDonald’s. While conducting our research we also came to know that KFC is more advertised this is one of the reasons that people prefer KFC over McDonald’s. We are going to discuss all of this in our research. 1. 2 HYPOTHESIS KFC is a spot light and McDonald’s is a side show. 1. 3 AIMS AND OBJECTIVES The trend of fast food is increasing day by day in Pakistan, this research is designed to generate knowledge about fast food restaurant in Pakistan, and hence this research is based upon two leading fast food brands in Pakistan. The main objective is to know that which brand is popular among majority. Which among the two brands is of higher quality. Which brand is more economical . Hence in general we conducted this research because we wanted to know that which brand is preferred and what is the reason behind it. 1. 4 SAMPLING In sampling plan we draw sample, sample is basically a segment of the population selected for research to represent the population as a whole. In our research we targeted people from 18 to 30 . So we approached people who visit KFC and McDonald’s . Our sample size is 40 from the whole population . Our research instrument for collecting primary data is Questionnaire in which we ask twenty questions, all are close ended for accessing people’s preference. 1. 5 METHODOLOGY The empirical analysis of the â€Å"International fast food chains in Pakistan† was based on the primary data collected through personal observations by visiting KFC and McDonald’s located in the twin cities of Rawalpindi and Islamabad. The data were collected by filling questionnaire during rush hours in the afternoon between 12:00 noon to 2:00 p. m. In all, 40 customers were accounted for during the survey time period in KFC and McDonald’s. The data were collected during the first week of January 2010. 1. 6 LITERATURE REVIEW First we will take into account the history of KFC. The company was founded as Kentucky Fried Chicken by Colonel Harland Sanders in 1952, though the idea of KFC’s fried chicken actually goes back to 1930. The company adopted the abbreviated form of its name in 1991. Perfecting its secret recipe of 11 herbs and spices in 1939, KFC has come a long way. With over 10,000 outlets in the world, KFC has maintained its title, for the last 60 years, of being the chicken Experts. Now we will discuss the history of McDonald . At one time it was the largest global restaurant chain, but it has since been surpassed by multi-brand operator, in the competitor KFC is on top of the list. The business began in 1940, with a restaurant opened by brothers Dick and Mac McDonald in San Bernardino, California. The present corporation dates its founding to the opening of a franchised restaurant by Ray Kroc, in Des Plaines, Illinois, on April 15, 1955. Now McDonald’s is present in 120 countries with about 32000 outlets. Market entry in Pakistan was not a big problem for KFC as it is a well-known international brand. In that stage they did promoted through their own brand. Their promotion statement was â€Å"KFC in Pakistan†. Opening the first KFC outlet in Gulshan-e- Iqbal in 1997. KFC wore the title of being the market leader in its industry. Serving delicious and hygienic food in a relaxing environment made KFC everyone’s favorite. Since then, KFC has been constantly introducing new products and opening new restaurants for its customers. Presently KFC is branched out in nine major cities of Pakistan (Karachi, Lahore, Gujranwala, Sukkur & Muree) with more than 45 outlets nation-wide. Apart from fulfilling our commitment of serving delicious, fresh and hygienic food and at the same time providing our customer with the ultimate entertainment; KFC also plays in the economics development of our country. Presently KFC has provided to over 1200 Pakistanis, which adds up to 6000 individuals directly dependent in KFC Pakistan. In introduction stage KFC entered the market using market-skimming strategy. Their products were high price and targeted only upper class. Later they introduced packages which were affordable by many people. McDonald’s Pakistan opened its doors in September 1998 at Lahore and presently operating in seven major cities with a network of 20 restaurants. With a strong belief in the Ray Krock phrase when you are green you are growing, McDonald’s Pakistan has an aggressive plan to expand in all other cities of Pakistan and is rapidly growing with the focus to provide friendly and quick service restaurant experience to their customers. Today millions of Pakistanis place their trust in McDonald’s everyday to provide them with food of a very high standard as well as good service. In the past five years, the response to McDonald’s coming to Pakistan has been overwhelming. McDonald’s located in Pakistan are currently employing about 1,000 Pakistanis and each store is managed by Pakistani managers. They have also contributed in other ways than food service. McDonalds has investment of over Rs 300 crore in the country and payment of taxes and duties amounting to more than Rs 100 crore. Since McDonald’s is doing so well in Pakistan they will continue to grow and add more stores in more cities in the future. But in Pakistan McDonald’s is facing a tough competition by KFC. KFC and McDonald’s serve to dominate the fast food business in Pakistan. Both fast food chains serve all their customers effectively, given the different categories and factors that determine the success of restaurants and fast food chains in Pakistan. However, based on the findings of the previous research, it can be perceived that KFC is running a more successful business in Pakistan, compared to the business run by McDonald’s. This was given proof in the article, based on the many and varied responses of customers to surveys, which involve their evaluation of both fast food restaurants, based on a number of factors, namely, food, service, environment, price, convenience, brand, and promotion. In terms of food, although both fast food restaurants almost have the same varieties, certain differences can still be recognized. Both KFC and McDonald’s offer chicken and hamburger meals including snacks, desserts, and drinks. However, only KFC offers a wide range of healthy side dishes, such as mashed potato, carrot muffin, and lotus fresh vegetable side dishes. In this sense, KFC aims to uphold healthy eating and nutrition of their customers. In addition, it has been emphasized in the case study that KFC appeared to have the upper hand over McDonald’s in terms of introducing new products in the market. Most of the new products of KFC, such as its lunch items, suit the tastes of the Pakistani. KFC has also been introducing new products in the market in a regular rate. In terms of environment and service, although both fast food restaurants appeal to their market due to their convenient lighting, cleanliness, music, and decorations, still, KFC serves to have the upper hand over McDonald’s. Based on the survey, more customers are â€Å"Very Satisfied† with the services and environment of KFC over McDonald’s. This is because the waiting time in McDonald’s is too long, compared to KFC. In addition, it can also be perceived that KFC has more advantage than McDonald’s, as the employees in KFC have less time to interact with customers than its counterpart, as the volume of its business is larger. The prices of food offered by both restaurants equally serve each other. However, the food offered by KFC is slightly higher, being able to offer some meals that are not offered by McDonald’s, such as the Family Bucket, Garden Chicken Burger Meal, and Hot & Spicy Wing Meal. Nevertheless, the volume of customers in all given times of day, in both weekdays and weekends is still higher in KFC than in McDonald’s. Given such figures, it can be perceived that more customers prefer KFC to McDonald’s, thus, indicative of the fact that KFC runs a more successful business than its counterpart does. Moreover, the findings of the study indicate â€Å"More low income and high income customers prefer KFC to McDonald’s, while average income customers prefer McDonald’s more than KFC† In this sense, it can be observed that KFC has a wider range of customers compared to McDonald’s, thus, indicating that more customers patronizes KFC. Furthermore, for the finale, the proof that KFC is running a more successful business than McDonald’s is indicated that not just in Pakistan KFC has an upper hand but in all over the world. 1. 7 DELIMITATIONS. The problem which we faced while conducting our research are firstly the people were not very co operative in order to fill our questionnaire and we have to convince them. Another problem was that people were hesitating to fill our questionnaire. 1. 8 DATA COLLECTION Q1) What is your age group? As we have taken our sample between 18-32. So the people who have filled the form have age between 18 to 32. Q2) What is the reason of eating fast food? Q3) How often do you use fast-food services? Q4) What’s your favorite fast food place? Q5) Rate the fast food you have visited the most? (3 being high and 1 being low). Q6) Which one is your favorite meal? Q7) What fast food restaurants do you think is most advertised? Q8) Which fast food chain is in your opinion is more healthy? Q 9) How favorable is your attitude towards the fast food brands you have eaten? (3 being high and 1 being low) Q10) How well the following brands satisfy your needs? (3 being high and 1 being low) Q11) Which brand packaging has an attractive look? (3 being high and 1 being low) Q12) Which fast food restaurant has an eye-catching outlook? Q13) Which brand do you think bring pleasant memory? (3 being high and being low) Q14) Which brand do you think earns pleasant money? Q15) On Average how much would you expect to pay for a fast food meal? Q16) Apart from food which place is more enjoyable? Q17) Which fast food restaurant is more accessible? Q18) Which brand offer deals which have attractive prices? Q19) If you owned your own fast food restaurant, then which fast food restaurant attribute you want to follow-up? 20) Do you think the future of international fast-food chains in Pakistan is bright? 1. 9 DATA ANALYSIS Q1) What is your age group? As we have taken our sample between 18-32. So the people who have filled the form have age between 18 to 32. Q2) what is the reason of eating fast food? The main reason that people eat at fast food restaurants is because they like the taste. Customer wouldn’t keep coming back to a restaurant if the taste of food does not satisfy their tongue. As pie graph shows that 82% prefer taste, 13% prefer convenience and 5% price, hence price and convenience element occupies a very small part of it, only the good taste allows and agree people to spend their money on food. Q3) How often do you use fast-food services? 54% visit once a month 12% visit once a year and once a week. 17% twice a week and 5% visit other time. It looks like most of the people go out and eat fast food once a month. In a close second place people visit fast food restaurants twice a week. So pie graph result shows that people like to eat fast food, but just at different interval of time. Q4) What’s your favorite fast food place? There are tons of different fast food restaurants around the world, but we narrowed down the choices to McDonald’s and KFC. According to the people’s choice 80% people like KFC while only 20% McDonald’s. KFC dominates over McDonald’s, other questions also represent that people are more likely towards KFC services. Q5) Rate the fast food you have visited the most? (3 being high and 1 being low) 62%of the people prefer to visit KFC while only 15% prefer McDonald’s. KFC are the first movers of fast food restaurant in Pakistan hence they have first mover advantage. They were the pioneer of fast food in Pakistan. The position of KFC in the mind of people is very strong. Q6) Which one is your favorite meal? We gave various choices of food offered by both restaurants. We restrict people only to choose one food item which is one of their most favorite According to the result 52% people like KFC chicken and 43%burger and 5% salad. While McDonald’s salads were liked by 45%, 30% burger and 25% chicken pieces. Q7) What fast food restaurants do you think is most advertised? The survey shows a slight difference between the advertisements of both restaurants. As they are leading fast food restaurants in Pakistan so they advertised almost equally to make their roots strong in promoting their service. According to the data 57% people think KFC is more advertised and 43% found McDonald’s is more advertised. Q8) Which fast food chain is in your opinion is more healthy? 67% people think that KFC is healthier. People have positive approach towards KFC because KFC food has less chronic health risks because its meal involves appropriate amount of nutrients. Q9) How favorable is your attitude towards the fast food brands you have eaten? (3 being high and 1 being low) 55% people rated KFC at 3 place, 37% people at second and 8% people at first place. But MacDonald’s result differ 13% people rated KFC at 3 place, 37% people at second and 50% people at first place. As results undoubtedly shows the people have favorable attitude towards KFC. Q10) How well the following brands satisfy your needs? (3 being high and 1 being low) 50% people are fully satisfied with KFC, 40% people satisfied and 10% people are just satisfied. But MacDonald’s result differ 15% people are fully satisfied, 35% people are satisfied and 50% people are just satisfied. Q11) Which brand packaging has an attractive look? (3 being high and 1 being low) In brand packaging McDonald’s took prize over KFC. The surveys result shows that 62%people like McDonald’s packaging style while only 27% people like KFC packaging style. Q12) Which fast food restaurant has an eye-catching outlook? Although in other aspects KFC has surpass McDonald’s but when it comes to the outlook of the restaurant 63% people like the outlook of McDonald’s and only 37% people rated KFC. Q13) Which brand do you think bring pleasant memory? (3 being high and being low) Pleasant memory associated with good environment of the place and taste of the food. After analysis it was found that 60% people’s pleasant memory is associated with KFC. 32% people have KFC. 8% do not have as much pleasant memories as others. Q14) Which brand do you think earns pleasant money? 55% people views show that KFC earns pleasant money. And in a close second place 45%rated McDonald’s. Q15) On Average how much would you expect to pay for a fast food meal? 55% people expect to pay an amount of at least Rs. 500 on fast food meal. 30% agreed on paying Rs. 1000 while only 15% want to spend Rs. 1500. Q16) Apart from food which place is more enjoyable? The popularity of any restaurant is just not dependent upon the taste and price of food but it also depend upon the enjoyable environment which include play area for kids, happy meal and gifts. 52% people consider McDonald’s is more enjoyable but 48% people like the environment of KFC. Q17) Which fast food restaurant is more accessible? The result of this question shows an even split among both options. The increasing trend of fast food leads both restaurant branches to multiply in order to make them easy to get to. 53% people think KFC is more accessible while 47% think that McDonald’s is more accessible. Q18) Which brand offer deals which have attractive prices? The higher percentage of people found the prices of KFC more attractive than McDonald’s. According to the data 55% people found prices of KFC affordable and attractive. While that of 45% found McDonald’s prices smart. Q19) If you owned your own fast food restaurant, then which fast food restaurant Attribute you want to follow-up? The majority results show that KFC has won the race in our fast food survey. It is found that KFC fulfill the needs of its customers to some extent, so considering KFC as their ideal people would like to follow the success tracks of KFC in order to have bright future of their restaurant ahead. 75% people like to follow the attributes of KFC for their own restaurant and only 25% consider McDonald’s as their ideal. Q20) Do you think the future of International fast food chains in Pakistan is bright? Based on people answers, 85%agreed with the statement that the future of international fast-food chains in Pakistan is bright, 5% were not agreed on bright future and 10% people have no idea about this. With today’s hectic lifestyles, time-saving products are increasingly in demand; one of the most obvious examples is fast food. People want quick and convenient meals as a result, consumers rely on fast food . Knowing this, fast food providers are coming up with new ways to market their products that save time for consumers. All that make sense though because that is what â€Å"fast food† is supposed to mean†¦cheap, fast, and tasty. 1. 10 CONCLUSION The conclusion we have drawn after conducting our research is that the problem statement which we consider in our research is confirmed . Our hypothesis that KFC is in spotlight and McDonald’s is a side show was right and people prefer KFC over McDonald’s because of their good quality food and their reasonable price, hence KFC capture a large market than McDonald’s in Pakistan. 1. 11 RECOMMENDATION AND SUGGESTION After conducting our research we come to a point that about 80% people prefer KFC over McDonald’s here are some suggestions and recommendations to both the brands. Based on our research we suggest that McDonald’s should improve the quality of their food because majority of people found McDonald’s a less healthy option. It was also found that Macdonald’s satisfies the need of people to lesser extent, so McDonald’s should try hard to make up to the expectations of people. It was found by our research that although people prefer KFC over McDonald’s but they found the packing of McDonald’s more attractive than that of KFC, so KFC should work on their packing and make it more attractive. When it comes to outlook of the restaurant, majority of people like the outlook of KFC, so McDonald’s should improve their outlook. It was also found that KFC is better advertised; hence McDonald’s should work to promote their brand in order to capture a large volume of customer. Pakistan is a price sensitive market for many items and competition is intense, so McDonald’s should maintain their price packages. REFERENCES ?

How Flight Control Systems Stabilize Rockets

How Flight Control Systems Stabilize Rockets Building an efficient rocket engine is only part of the problem. The rocket must also be stable in flight. A stable rocket is one that flies in a smooth, uniform direction. An unstable rocket flies along an erratic path, sometimes tumbling or changing direction. Unstable rockets are dangerous because its  not possible to predict where they’ll go – they may even turn upside down and suddenly head directly back to the launch pad. What Makes a Rocket Stable or Unstable? All matter has a point inside called the center of mass or â€Å"CM, regardless of its size, mass or shape. The center of mass is the exact spot where all the mass of that object is perfectly balanced. You can easily find the center of mass of an object - such as a ruler - by balancing it on your finger. If the material used to make the ruler is of uniform thickness and density, the center of mass should be at the halfway point between one end of the stick and the other. The CM would no longer be in the middle if a heavy nail was driven into one of its ends. The balance point would be nearer the end with the nail. CM is important in rocket flight because an unstable rocket tumbles around this point. In fact, any object in flight tends to tumble. If you throw a stick, it will tumble end over end. Throw a ball and it spins in flight. The act of spinning or tumbling stabilizes an object in flight. A Frisbee will go where you want it go to only if you throw it with a deliberate spin. Try throwing a Frisbee without spinning it and youll find that it flies in an erratic path and falls far short of its mark if you can even throw it at all.   Roll, Pitch and Yaw Spinning or tumbling takes place around one or more of three axes in flight: roll, pitch and yaw. The point where all three of these axes intersect is the center of mass. The pitch and yaw axes are the most important in rocket flight because any movement in either of these two directions can cause the rocket to go off course.  The roll axis is the least important because movement along this axis will not affect the flight path. In fact, a rolling motion will help stabilize the rocket the same way a properly passed football is stabilized by rolling or spiraling it in flight. Although a poorly passed football may still fly to its mark even if it tumbles rather than rolls, a rocket will not. The action-reaction energy of a football pass is completely expended by the thrower the moment the ball leaves his hand. With rockets, thrust from the engine is still produced while the rocket is in flight. Unstable motions about the pitch and yaw axes will cause the rocket to leave the planned course. A control system is needed to prevent or at least minimize unstable motions. The Center of Pressure Another important center that affects a rockets flight is its center of pressure or â€Å"CP.† The center of pressure exists only when air is flowing past the moving rocket. This flowing air, rubbing and pushing against the outer surface of the rocket, can cause it to begin moving around one of its three axes. Think of a weather vane, an arrow-like stick mounted on a rooftop and used for telling wind direction. The arrow is attached to a vertical rod that acts as a pivot point. The arrow is balanced so the center of mass is right at the pivot point. When the wind blows, the arrow turns and the head of the arrow points into the on-coming wind. The tail of the arrow points in the downwind direction. A weather vane arrow points into the wind because the tail of the arrow has a much larger surface area than the arrowhead. The flowing air imparts a greater force to the tail than the head so the tail is pushed away. There is a point on the arrow where the surface area is the same on one side as the other. This spot is called the center of pressure. The center of pressure is not in the same place as the center of mass. If it were, then neither end of the arrow would be favored by the wind. The arrow would not point. The center of pressure is between the center of mass and the tail end of the arrow. This means that the tail end has more surface area than the head end. The center of pressure in a rocket must be located toward the tail. The center of mass must be located toward the nose. If they are in the same place or very near each other, the rocket will be unstable in flight. It will try to rotate about the center of mass in the pitch and yaw axes, producing a dangerous situation. Control Systems Making a rocket stable requires some form of control system. Control systems  for rockets keep a rocket stable in flight and steer it. Small rockets usually require only a stabilizing control system. Large rockets, such as the ones that launch satellites into orbit, require a system that not only stabilizes the rocket but also enables it to change course while in flight. Controls on rockets can be either active or passive. Passive controls are fixed devices that keep rockets stabilized by their very presence on the rockets exterior. Active controls can be moved while the rocket is in flight to stabilize and steer the craft. Passive Controls The simplest of all passive controls is a stick. Chinese fire arrows  were simple rockets mounted on the ends of sticks that kept the center of pressure behind the center of mass. Fire arrows were notoriously inaccurate in spite of this. Air had to be flowing past the rocket before the center of pressure could take effect. While still on the ground and immobile, the arrow might lurch and fire the wrong way.   The accuracy of fire arrows was improved considerably years later by mounting them in a trough aimed in the proper direction. The trough guided the arrow until it was moving fast enough to become stable on its own. Another important improvement in rocketry came when sticks were replaced by clusters of lightweight fins mounted around the lower end near the nozzle. Fins could be made out of lightweight materials and be streamlined in shape. They gave rockets a dart-like appearance. The large surface area of the fins easily kept the center of pressure behind the center of mass. Some experimenters even bent the lower tips of the fins in a pinwheel fashion to promote rapid spinning in flight. With these spin fins, rockets become much more stable, but this design produced  more drag and limited the rockets range. Active Controls The weight of the rocket is a critical factor in performance and range. The original fire arrow stick added too much dead weight to the rocket and therefore limited its range considerably. With the beginning of modern rocketry in the 20th century, new ways were sought to improve rocket stability and at the same time reduce overall rocket weight.  The answer was the development of active controls. Active control systems included vanes, movable fins, canards, gimbaled nozzles, vernier rockets, fuel injection and attitude-control rockets.   Tilting fins and canards are quite similar to each other in appearance - the  only real difference is their location on the rocket. Canards are mounted on the front end while tilting fins are at the rear. In flight, the fins and canards tilt like rudders to deflect the air flow and cause the rocket to change course. Motion sensors on the rocket detect unplanned directional changes, and corrections can be made by slightly tilting the fins and canards. The advantage of these two devices is their size and weight. They are smaller and lighter and produce less drag than large fins. Other active control systems can eliminate fins and canards altogether. Course changes can be made in flight by tilting the angle at which the exhaust gas leaves the rocket’s engine. Several techniques can be used for changing exhaust direction.  Vanes are small finlike devices placed inside the exhaust of the rocket engine. Tilting the vanes deflects the exhaust, and by action-reaction the rocket responds by pointing the opposite way.   Another method for changing the exhaust direction is to gimbal the nozzle. A gimbaled nozzle is one that is able to sway while exhaust gases are passing through it. By tilting the engine nozzle in the proper direction, the rocket responds by changing course. Vernier rockets can also be used to change direction. These are small rockets mounted on the outside of the large engine. They fire when needed, producing the desired course change. In space, only spinning the rocket along the roll axis or using active controls involving the engine exhaust can stabilize the rocket or change its direction. Fins and canards have nothing to work upon without air. Science fiction movies showing rockets in space with wings and fins are long on fiction and short on science. The most common kinds of active controls used in space are attitude-control rockets. Small clusters of engines are mounted all around the vehicle. By firing the right combination of these small rockets, the vehicle can be turned in any direction. As soon as they are aimed properly, the main engines fire, sending the rocket off in the new direction.   The Mass of the Rocket The mass of a rocket is another important factor affecting its performance. It can make the difference between a successful flight and wallowing around on the launch pad. The rocket engine must produce a thrust that is greater than the total mass of the vehicle before the rocket can leave the ground. A rocket with a lot of unnecessary mass will not be as efficient as one that is trimmed to just the bare essentials. The total mass of the vehicle should be distributed following this general formula for an ideal rocket:   Ninety-one percent of the total mass  should be propellants.Three percent should be tanks, engines and fins.Payload can account for 6 percent. Payloads may be satellites, astronauts or spacecraft that will travel to other planets or moons. In determining the effectiveness of a rocket design, rocketeers speak in terms of mass fraction or â€Å"MF.† The mass of the rocket’s propellants divided by the total mass of the rocket gives mass fraction:  MF (Mass of Propellants)/(Total Mass) Ideally, the mass fraction of a rocket is 0.91. One might think that an MF of 1.0 is perfect, but then the entire rocket would be nothing more than a lump of propellants that would ignite into a fireball. The larger the MF number, the less payload the rocket can carry. The smaller the MF number, the less its range becomes. An MF number of 0.91 is a good balance between payload-carrying capability and range. The Space Shuttle has an MF of approximately 0.82. The MF varies between the different orbiters in the Space Shuttle fleet and with the different payload weights of each mission. Rockets that are large enough to carry spacecraft  into space have serious weight problems. A great deal of propellant is needed for them to reach space and find proper orbital velocities. Therefore, the tanks, engines and associated hardware become larger. Up to a point, bigger rockets fly farther than smaller rockets, but when they become too large their structures weigh them down too much. The mass fraction is reduced to an impossible number. A solution to this problem can be credited to 16th-century fireworks maker Johann Schmidlap. He attached small rockets to the top of big ones. When the large rocket was exhausted, the rocket casing was dropped behind and the remaining rocket fired. Much higher altitudes were achieved. These rockets used by Schmidlap were called step rockets. Today, this technique of building a rocket is called staging. Thanks to staging, it has become possible not only to reach outer space but the moon and other planets, too. The Space Shuttle follows the step rocket principle by dropping off its solid rocket boosters and external tank when they’re exhausted of propellants.

Dhari's Research Paper Example | Topics and Well Written Essays - 2500 words

Dhari's - Research Paper Example Nevertheless, recent efforts in economic development like the high population and employment growth and the increases in construction, health care, petroleum and social assistance are brightening the outlook (Garcia and Paul, 2006). New Mexico has a small manufacturing base which in 2003 was 4.7% of the non-agricultural population compared to the national average of 11.2%. There has been a reduction in the number of farms in the last few decades and a matching increase of the size of farms with most of the state’s agricultural efforts focusing on livestock instead of produce. In the past, mining was considered a main sector; however, it decreasingly plays a significant role in the state’s economy of only 1.8% in 2002 compared to 2.8% in 1988 and 5.5% in 1978. Because of the small employment opportunities in manufacturing and industrial sectors, the state historically has had a high rate of unemployment, even in non-recessionary times, the state experienced unemployment rates higher than the country’s average. For instance in 1987 unemployment was 8.9% compared to the national rate of 6.2%; moreover, in 2003, the state’s jobless rate was 6.4% compared to 6% of the national average (Garcia and Paul, 20069). ... These contrasting averages point the disparities in education in the state’s various population groups; For instance, the poor, Hispanics and Indians average less educational attainment than other groups in the state (Garcia and Paul, 2006). Therefore, of the estimated 1,819,046 total population of New Mexico, 120,000 are legally documented immigrants and 40,000 are undocumented; thus, the undocumented population is less than 7% of the total state’s population (Aparicio, Philip and Kalyani, 2004). Currently, over three quarters of immigrants admitted to New Mexico are from Mexico; even though, immigrants also come from other nations like the Asian nations. Although Hispanics make the largest portion of immigrant population in the state, over 90% are native born, which is higher than the country’s average of over64%. Many of the immigrants travel across the Mexico-New Mexico border without permit because of economic hardships and eventually end up staying in the s tate; thus, the reasons for immigrants staying are simply economic. For instance, an immigrant may decide to work for indefinite period in order to save some money and then go back to his or her country. Although undocumented immigrants enter New Mexico for economic opportunities, their rate of employment is low; thus, vast majority of the undocumented Hispanics and other immigrants live below poverty, which contribute to the poverty status of the state. Unemployment is main source of contemporary poverty; moreover, regional economic restructuring coincides with cultural diversity in America resulting in spatial inequalities in geographic areas (Aparicio, Philip and Kalyani, 2004; Esparza and Angela, 2008). This is reflected by the large differences in income and
