Customer Service Policies Essay

Research has indicated that there are a number of areas of customer service that are a priority for people. In particular, delivery, timeliness, information, professionalism and staff attitude are deemed important. Aspects of these key areas include a prompt initial contact with the customer and the ability to keep to agreed timescales, provision of accurate and detailed information with regular development updates, keeping promises and dealing with problems and issues in a professional and timely manner. Throughout all contact with customers, staff should aim to meet their needs through professional, courteous and efficient service. Staff will: * treat all customers with respect and courtesy; * listen to what customers have to say; * personalise service to the needs and circumstances of each service user where practical; * always do what they say they are going to do, or update the appropriate people promptly if things change, offering an explanation for the change; * respond to enquiries promptly and efficiently; * consult customers about their service needs Customer service is an organization’s ability to supply their customers’ wants and needs. Excellent customer service is the ability of an organization to constantly and consistently exceed the customer’s expectations. Accepting this definition means expanding our thinking about customer service; if we’re going to consistently exceed customers’ expectations, we have to recognize that every aspect of our business has an impact on customer service, not just those aspects of our business that involve face-to-face customer contact. Improving customer service involves making a commitment to learning what our customers’ needs and wants are, and developing action plans that implement customer friendly processes.

Although customer policies are unique to each business ,there are still some guiding principles that all corporations should adopt. Successful customer service policies are guided by the following principle: knowing what your customers want and delivering on it .Having only a vague idea of what customers want means there can be no concrete policy in place for when problems or misunderstanding arise. Knowing what customers want will also lead to correct business decisions. In order to be competitive ,all businesses must have outstanding customer service practices and policies. Customer policies and relationship standards should be part of your mission statement, neither receiving substandard or preferential treatment over employees, contractors ,or even stakeholders. Providing great customer service is a great step in building a relationship with your clients. The greater the relationship you develop ,the more likely it is that your client will become an evangelist for your brand and your organization. Customer service department need way to measure their success. Employees can’t expect to provide your idea of great service if they don’t know what that means. In the book Award-Winning Customer Service, Renee Evenson writes ‘’Before you can expect the people in your organization to provide outstanding customer service ,they have to know how to give outstanding customer service.’’ Policies set service guidelines and train employees. Customers demand to be treated like their money matters .Having a policy is a pre-requisite to business. Just providing a body in a store to answer questions or having enough staff in a call centre to answer calls quickly will go unnoticed. A customer service policy is a way to design a standard to go beyond expectations. A customer service policy is a tool to give guidance to employees on how to solicit information from customers to improve products. Train your staff to be problem-solvers and to incorporate up-sell tactics to capitalize on the doors they’ve open by providing great service.

Applying theory of career construction to case study

Applying theory of career construction to case study The purpose of this case study is to apply Savickas’ Theory of Career Construction to a volunteer client Karen. Complete a narrative interview using the structured interview questions in the Career Style Interview, and employing the six steps. Discuss interpretations, observations and obtain her feedback. Theoretical foundation of Career Construction Theory The theoretical foundation of Career Construction theory (CCT) has its beginnings from Constructivism, and according to Sharf (2009) Constructivism is a psychological approach that has developed out of a postmodern philosophical position. It has been stated the Postmodernism period was a â€Å"reaction to modernism†, in that it highlighted the differences in individual views rather than a one-sided, rational scientific view of modernism. (Sharf 2009) Constructivist saw individuals as creators of their own destiny, and constructivist counselors sought to help clients discover that meaning and resolve any discrepancy. (Sharf 2009) According to (Sharf 2009, p316) the constructivism approach was greatly affected by the changing of the work environments in the 1970’s. Employees were no longer staying with one position for their whole work life, as companies were becoming â€Å"less loyal† to employees and watching out for own bottom-line by â€Å"downsizing† their workforce to â€Å"part-time†. Employees soon discovered they needed to take charge of their future and looked to career counselors for help. According to (Busacca, 2007) constructivist career counseling attempts to answer one question â€Å"how can an individual negotiate a lifetime job changes and not lose a sense of self?† Career construction theory (CCT) came about to help individuals develop meaning out of their career choices and actions. CCT addresses how an individual’s â€Å"career†, is made from its personal and social constructs or interactions. These constructs are not actual re al reality, but an individual’s representation of that reality. CCT defines career as an objective and subjective construct. Objectively speaking, career is a listing of positions from the past to present. Subjectively, career is the personal meaning or a pattern of experiences from past, present and future. (Savickas, 2005, p43) CCT is made of three distinct perspectives and each seeks to determine how the individual views their life and career, and how they work together. (Busacca, 2007) These perspectives are life theme, career adaptability, and vocational personality. The Purpose and the Suppositions The purpose of CCT is to help the individual discover the subjective meaning in their work. In helping the individual discover this type of meaning, CCT stress the importance of the relationship between the individual and the counselor. Life themes In Holland’s career development theory, his inventories were used to obtain critical information about the individual, and make predictions about a career path, and also the likely hood of success along this path. Career construction theory takes advantage of the individual’s narrated work stories to discover any meanings or patterns. (Busacca, 2007) It has been stated that â€Å"pattern is the primary unit of meaning†. â€Å"By consciously organizing and binding together these discrete experiences, a unifying life theme patterns† (Savickas 2005, p 58) â€Å"patterns becomes a fundamental and essential way of being because it provides a way for individuals to see themselves and see what is important in the world.† (Savickas, 2005 p58)

How Effective Are Educational Programmes in Improving Self-Management Essay

How Effective Are Educational Programmes in Improving Self-Management for Patient with Type 2 Diabetes - Essay Example Findings: The findings indicated women were more responsive to such studies than men. Nearly 50% of the patients showed good progress in all five parameters like reduction in weight, increased psychological health and good control over glycaemic level. In the rest, 30% people showed good improvement in three of five parameters and the rest showed good improvement in any two parameters. The study was conducted over a period of 12 months time and the post-study monitoring was continued for one more year. Conclusion: The self-management studies for Type 2 diabetes patients are very effective provided they are given in a friendly and locally accepted form, rather than in an experimental way. Introduction The Center for Disease Control website states nearly 17 million people in the US have diabetes. It accounts to nearly 6.2% of the total countries population. WHO says one in 10 adults worldwide have diabetes. It identifies Hypertension and Obesity as the main causes for the drastic incre ase in the illness. In Europe nearly 5% of the total population is affected by Diabetes (IDF, 2007). In fact, the country implements rewards for primary health care centres controlling diabetes within their region effectively (Khunti, K et al, 2007). Most of the people suffer from this condition because of lack of awareness. "Had I known earlier, I would have avoided ..." is a common phrase heard from the new diabetes patients. Even after the advent of the diabetes many people are clueless about how to handle the situation. This study aims in measuring the effectiveness of the self-education programmes among the patients suffering from type 2 diabetes. It analyses various studies conducted on the subject by many scholars and put forward a unique and effective plan to improvise the same. Objectives of the Study 1. The patient, his immediate family members and friends should understand the root cause of the illness and why it occurred. 2. Several sugar patients are completely ignore t he wounds in their body, which leads to several complications like amputation (Massi-Benedetti, 2002). Hence, the patients are taught exactly how to take care of themselves properly. 3. Patients are educated about taking proper medications on time and the dangers of missing them. They know how to handle themselves in times of emergency. 4. They are capable of checking their blood glucose level regularly and indicate proper results to the doctors. 5. They are well aware of the fatal side effects of the illness like cardiovascular diseases and take appropriate measures like doing regular exercises and following a proper diet to avoid the same. Literature Review â€Å"Diabetes mellitus (diabetes) in adults is a global health problem. It is a disorder of the endocrine system characterised by abnormal fluctuations in blood glucose levels, usually related to a defect in insulin production and glucose metabolism† (Dunning 2003).Diabetes starts as a mild illness. In course of time it can cause fatal side effects like amputation, blindness, stroke and cardiovascular illness. In addition to physical issues, patients undergo severe stress due to uncontrollable glycaemic level in the body. Years of health negligence, lethargic lifestyle and dumping of sugary foods is the main cause to the

THE ECHR AS A LIVING INSTRUMENT Essay Example | Topics and Well Written Essays - 2500 words

THE ECHR AS A LIVING INSTRUMENT - Essay Example One of the powerful interpretive tools used by the EctHR has been the conceptualization of the ECHR as a living instrument. It is settled case law that the ECHR is â€Å"a living instrument which must be interpreted in light of present-day conditions.† A critique of judicial activism may criticize the use of the living instrument rule as an impermissible intrusion of the Strasbourg Court into the policy-making domain. This paper analyses this proposition and the development of the living instrument rule in light of Strasbourg jurisprudence in respect of two articles of the ECHR, article 3 and article 8. Article 3 of the ECHR states that no one shall be subjected to torture or to inhuman or degrading treatment or punishment. The original Court began the articulation of the living instrument methodology in the well-known case of Tyrer v. United Kingdom when it was required to determine the compatibility of judicial corporeal punishment with article 3 prohibition on cruel and degrading punishment. The Government of the Isle of Man argued that judicial corporal punishment was acceptable to the inhabitants of the island. However, the Court held that: â€Å"... the Convention is a living instrument which, as the Commission rightly stressed, must be interpreted in the light of present-day conditions. In the case now before it the Court cannot but be influenced by the developments and commonly accepted standards in the penal policy of the member States of the Council of Europe in this field.

Business Ethics Research Paper Example | Topics and Well Written Essays - 2500 words

Business Ethics - Research Paper Example In order to gets acceptance from the government as well as the bodies controlling policies and laws, organizations have to accept and follow certain rules and regulations and maintain certain standards in the work process. A collaborative study of these regulations, laws and issues can be termed as business ethics. Ethics is always concerned with the moral judgment of business.

Fabrication of a Reinforced Concrete Beam Lab Report

Fabrication of a Reinforced Concrete Beam - Lab Report Example Thirdly this gives sufficient space for the main reinforcement to develop full stressing and strength, which consequently prevents slipping of the bars. Lastly a sufficient cover gives a smooth surface which improves the aesthetics of the component as well. 3. 4. Bar codes are on the schedule so that the reader must understand that how the steel bar is is to be bended and what angles and shapes are to be made. In addition to this the reader can easily calculate the length of the bar, and consequently by using the diameter and the type of bar the total weight of the bar can be calculated and finally the total weight of the reinforcement. 5. The cover can be maintained by different methods. One method can be made by placing Metal plastic tipped bar chairs under the reinforcement so that a specified height can be maintained between the bottom surface and reinforcement. Then another method is to give spacer blocks, these can be small marble pieces or concrete plates. Another method used for very heavy reinforcement is the employment of Plastic strip bar chairs. 6. a) coarse aggregate = 122.4 Kg b) fine aggregate = 81.6 Kg c) cement = 40 Kg d) water = 22 Kg 7. Water cement ratio of the concrete is (weight of water / weight of cement ) is w/c = 22/40 = 0.55 SSD or saturated surface dry is a condition of the aggregate when all the surface pores of aggregate are fully filled and there is no excess water on its surface. In addition no more water will be absorbed by the aggregate when immersed in water. This aspect is important because if the aggregate is not saturated then it will start absorbing the water of the concrete which was supposed to be consumed in the hydration of the concrete. If there is less water in the concrete than required the concrete will not acquire the desired strength and the concrete will have microscopic cracks further weakening the concrete and this will also disturb the desired water cement ratio. Then this state helps in finding the absorptio n value of aggregates and also the specific gravity of aggregate. Lastly the aggregate must be saturated surface dry as the dry surface will help and ensure a good bond between the concrete and aggregate. 8. A clean beam form is important because presence of any loose material will attach on the surface of the beam and when the beam is subjected to bending the concrete around this loose material and the loose material it self will spall off. Hence the cover would be compromised and there is a chance that the steel reinforced will be naked and prone to environment resulting into its rusting and corrosion. 9. The indication of completion of the compaction is that the firstly there is no decrease/ decay in volume or height of the concrete and the movement of aggregates due to vibration in the concrete will very low. In addition the final indication is that the water will come on the surface of the concrete and it must be noted that as soon as the water film appears on the surface of th e concrete the vibrator must be pulled out of the concrete or else the concrete will segregate, resulting into separation of cement paste and aggregate. 10. The compaction of concrete is very important for its acquisition of desired strength, In essence compaction is the process in which the entrapped air is released from the

Sir Alex Ferguson Essay Example | Topics and Well Written Essays - 250 words

Sir Alex Ferguson - Essay Example The father’s glorious success both as a player and as a manager was mainly built on hard work and patience since his early years in the field. With the age of sixteen, Ferguson started his career as a player at Stranraer Club in 1956 and for three years. After that and over the following years he joined many other clubs including St Johnstone, Dunfermline Athletic, Rangers, and finally Falkirk, Ayr United in 1969 just to become a manager in 1974. East Stirling was really the starting point for Sir Alex Ferguson from which he moved from one place to another trying to reveal his managerial skills. A few years later, Ferguson got his life chance to be the manager of Aberdeen where he stayed for eight years and won many matches on top of which are three league championships and four Scottish Cups. For years Ferguson demonstrated his brilliant managerial strategies leading the team from one victory to another. Sir Alex Ferguson’s years of experience led him to a bigger experience; in 1986 he was appointed as the manager at Manchester United. The early years of being a manager for such a big team were really difficult. Four years later he was able to win over Crystal Palace in the FA Cup Final replay; this game was the start of unprecedented success for years to come. It is true that Ferguson’s managing history with Manchester United is considered the longest in sports history (Kelly 1997) which definitely added to his rich resume. A list of his achievements will definitely include that he was entitled the Manager of the Year more than anyone else in the British football history. In 2008, Sir Alex Ferguson became the third manager in England who wins the European Cup more than once. In 1999, Sir Ferguson was knighted for his services in the football field. Sir Alex Ferguson has won around 46 trophies as a manager, which vividly makes him the best manager in the history of

Citizen involvement with their law enforcement agency Essay

Citizen involvement with their law enforcement agency - Essay Example Citizen involvement in the law enforcement agencies is something that is in a way well ingrained in the American law enforcement mechanisms (Marx & Archer, 1971, p. 52). In the nascent era of American civilization, whenever the citizens felt that there is a lot of crime that threatens their well being, their property, there sense of peace and the values and norms they cherished as individuals and groups, varied types of initiatives used to be engaged in that involved a close collaboration with the law enforcement agencies (Marx & Archer, 1971, p. 52). In the 9/11 scenario, when the law enforcement agencies are hard pressed in terms of time, resources and personnel, soliciting citizen involvement could turn out to be a viable way out of this crunch. Introduction There is no denying the fact that citizen involvement in the law enforcement agencies tend to involve a range of possibilities and ambiguities as to the role that the citizens play in law enforcement. The biggest premise that supports such line of reasoning is the belief that citizens may be more than happy to engage with the law enforcement agencies. Such discussion tend to take it for granted that it is possible for the citizens and the neighbourhoods and the law enforcement agencies to work in close tandem and coordination to deal with law enforcement issues and problems. Such forums also talk about the possible way that the law enforcement agencies could help in the development of the neighbourhoods. Yet, the reality is that much research and surveys do tend to convey the fact that soliciting citizens’ involvement in the law and order problems is something that is easier said than done. Well, both the sides that are the neighbourhoods and the law enforcement agencies happen to be responsible for this lacuna. While, on the one side if citizens feel scared and threatened by the possibility of engaging in law and order issues, the law and order agencies also sometimes evince a scarce initiative t o organize and retain active community participation in their day to day affairs. However, in the last few decades a belief has emerged amongst the law and orders agencies that the onus of crime prevention happens to a large extent being dependent on the communities and the law and order bodies are mostly required to play an ancillary role in the task of maintaining social harmony and peace. Hence, in the current times when the law and order agencies are hard pressed for personnel and resources, citizen involvement could indeed emerge to a potential game changer. Citizen Involvement It goes without saying that citizens can play a pivotal role in the working of law enforcement agencies in a variety of ways. The citizens could supplement and assist the law enforcement agencies in the carrying out of their duties, without putting any unnecessary burden on the budgetary resources (Wadington, 1999). Citizens can assist organizations in a variety of ways that includes, resident policing o f communities, citizen surveillance of neighbourhoods aimed at reporting any suspicious activities to the law enforcement agencies, citizen patrols aimed at bolstering the neighbourhood confidence, citizen initiatives aimed at prying on and reporting about specific types of criminal activities, clerical or supportive administrative chores, extending support to the victims of crime, as reserves, computer programming, translation services, and support extended

Biology Essay Example | Topics and Well Written Essays - 750 words - 4

Biology - Essay Example The other is the â€Å"good cholesterol† which is contained within the high-density lipoprotein and is considered to have beneficial actions on the human beings. Cholesterol can have good effects on the human body and it is because of this that the researchers have termed it as being beneficial under some set conditions. What this means is that cholesterol has got a physiological role in the human body and thus anything in excess is pathogenic and could lead to the harmful effects that come part and parcel with cholesterol. As per the good aspects, we find out that the metabolism of cholesterol is regulated and controlled by enzymes that are different in nature and shape as well as the receptors present within the human body. Cholesterol makes for an effective transferring process of the proteins which are present within the liver, small intestine, peripheral cells and plasma. Cholesterol helps in digestion of dietary fats as well as the production of many different hormones. There is evidence that with the increase of high-density lipoprotein within the human body, longevity could be expected, which surely is a positive sign related with ch olesterol. Cholesterol always helps in building the cell walls and is thus a good agent within the human body from this perspective. For cholesterol to always remain as a beneficial entity there is a dire need to have its intake in a very conservative fashion so that the related excess does not create coronary heart disease and other risks which are closely associated. Cholesterol is an equally good building block as far as Vitamin D is concerned. It helps the sex hormones and different important chemicals are made up due to the presence of cholesterol. Also cholesterol helps at building the structure as well as the function of the invaginated caveole and the clathrin-coated pits. There is a serious role of cholesterol within the synthesis and intake regimes of a human diet and is synthesized

Chinese Civilization Essay Example for Free

Chinese Civilization Essay The land here is broad and diverse. Among this immense piece of earth, one can find both farmer and businessman; mountain and plain; drought and rainfall; wasteland and farmland. It is vast, it is multifaceted. And yet these collections of disparate and dissimilar presences are bound as one, side by side with each other. They are together, they are connected. They are united, united under one name: China. It is impossible to choose a single word that exactly represents all the land of China. The Himalayan Mountains might have majesty, or the Forbidden City might have opulence, but certainly the two are quite different and cannot be swapped. Yet there is a word that can describe all the land of China: the cities, the mountains, the villages, the plains, the towns, the rivers, the deserts. That word is Beauty. Chinas cultural sphere has extended across East Asia as a whole, with Chinese religion, customs, and writing systems being adapted to varying degrees by neighbors such as Japan, Korea and Vietnam. The first evidence of human presence in the region was found at the Zhoukoudian cave. It is one of the first known specimens of Homo erectus, now commonly known as the Peking Man, estimated to have lived from 300,000 to 780,000 years ago China ranges from mostly plateaus and mountains in the west to lower lands in the east. Principal rivers flow from west to east, including the Yangtze (central), the Huang He (Yellow river, north-central), and the Amur (northeast), and sometimes toward the south (including the Pearl River, Mekong River, and Brahmaputra), with most Chinese rivers emptying into the Pacific Ocean. In the east, along the shores of the Yellow Sea and the East China Sea there are extensive and densely populated alluvial plains. On the edges of the Inner Mongolian plateau in the north, grasslands can be seen. Southern China is dominated by hills and low mountain ranges. In the central-east are the deltas of Chinas two major rivers, the Huang Heand Yangtze River. Most of Chinas arable lands lie along these rivers, and they were the centers of Chinas major ancient civilizations. Other major rivers include the Pearl River, Mekong, Brahmaputra and Amur. Yunnan Province is considered a part of the Greater Mekong Subregion, which also includes Myanmar, Laos, Thailand, Cambodia, and Vietnam. [47] In the west, the north has a great alluvial plain, and the south has a vast calcareous tableland traversed by hill ranges of moderate elevation, and the Himalayas, containing Earths highest point, Mount Everest. The northwest also has high plateaus with more arid desert landscapes such as the Takla-Makan and the Gobi Desert, which has been expanding. During many dynasties, the southwestern border of China has been the high mountains and deep valleys of Yunnan, which separate modern China from Burma, Laos and Vietnam. The Paleozoic formations of China, excepting only the upper part of the Carboniferous system, are marine, while the Mesozoic and Tertiary deposits are estuarine and freshwater, or else of terrestrial origin. Groups of volcanic cones occur in the Great Plain of north China. In the Liaodong and Shandong Peninsulas, there are basaltic plateaus. Part II CONTRIBUTIONS Society. Hundreds of ethnic groups have existed in China throughout its history. The largest ethnic group in China by far is the Han. This group, however, is internally diverse and can be further divided into smaller ethnic groups that share similar traits. Over the last three millennia, many previously distinct ethnic groups in China have been Sinicized into a Han identity, which over time dramatically expanded the size of the Han population. However, these assimilations were usually incomplete, and vestiges of indigenous language and culture still often remain in various regions of China. Because of this, many within the Han identity have maintained distinct linguistic and cultural traditions while still identifying as Han. Several ethnicities have also dramatically shaped Han culture, e. g. the Manchurian clothing called the qipao became the new Chinese fashion after the 17th century, replacing earlier Han styles of clothing such as the Hanfu. The modern term Chinese nation (Zhonghua Minzu) is now used to describe a notion of a Chinese nationality that transcends ethnic divisions. China has over 50 minority groups. Each group has different languages, customs, and traditions. Gap between the Rich and the Poor. The Chinese society was structurally complex and not much is known about it. Research is still on. Life in old Chinese society on a normal working day was hard and industrious for the farmers while luxurious and laid back for nobles and merchants. There was a wide demographic gap between the farmers and kings and nobles. The farmers were far more in population as compared to nobles. They were economically exploited and were made to work very hard. The nobles lived in luxurious palaces while the farmers in China survived in small huts. Naturally the nobles were highly regarded and lived with great riches. Religion. There are three main religions in China. They are Confucianism, Buddhism, and Taoism. They were suppressed by the CCP during the 20th century, but they are still alive and penetrating the minds of Chinese today. These religions are all widespread, and aside from other world religions, they all originated in China. Confucianism was the official philosophy throughout most of Imperial Chinas history, and mastery of Confucian texts was the primary criterion for entry into the imperial bureaucracy. Chinas traditional values were derived from various versions of Confucianism. A number of more authoritarian strains of thought have also been influential, such as Legalism. There was often conflict between the ideas and philosophies, for example, the Song Dynasty Neo-Confucians believed Legalism departed from the original spirit of Confucianism. Examinations and a culture of merit remain greatly valued in China today. In recent years, a number of New Confucians (not to be confused with Neo-Confucianism) have advocated that democratic ideals and human rights are quite compatible with traditional Confucian Asian values. With the rise of European economic and military power beginning in the mid-19th century, non-Chinese systems of social and political organization gained adherents in China. Some of these would-be reformers totally rejected Chinas cultural legacy, while others sought to combine the strengths of Chinese and European cultures. In essence, the history of 20th-century China is one of experimentation with new systems of social, political, and economic organization that would allow for the reintegration of the nation in the wake of dynastic collapse. Economics. By roughly 10,000 BCE, in the Neolithic Era, agriculture was practiced in China. Stratified bronze-age cultures, such as Erlitou, emerged by the third millennium BCE. Under the Shang (ca. 1600–1045 BCE) and Zhou (1045–771 BCE), a dependent labor force worked in large-scale foundries and workshops to produce bronzes and silk for the elite. The agricultural surpluses produced by the manorial economy supported these early handicraft industries as well as urban centers and considerable armies. This system began to disintegrate after the collapse of the Western Zhou Dynasty in 771 BCE, preceding the Spring and Autumn and Warring states eras. As the feudal system collapsed, much legislative power was transferred from the nobility to local kings. A merchant class emerged during the Warring States Period, resulting in increased trade. The new kings established an elaborate bureaucracy, using it to wage wars, build large temples, and perform public works projects. This new system rewarded talent over birthright; important positions were no longer occupied solely by nobility. The adoption of new iron tools revolutionized agriculture and led to a large population increase during this period. By 221 BCE, the state of Qin, which embraced reform more than other states, unified China, built the Great Wall, and set consistent standards of government. [5] Although its draconian laws led to its overthrow in 206 BCE, the Qin institutions survived. During the Han Dynasty, China became a strong, unified, and centralized empire of self-sufficient farmers and artisans, though limited local autonomy remained. The Song Dynasty (960–1279 CE) brought additional economic reforms. Paper money, movable type, the compass, and other technological advances facilitated communication on a large scale and the widespread circulation of books. The state control of the economy diminished, allowing private merchants to prosper and a large increase in investment and profit. Despite disruptions during the Mongol conquest of 1279, the Ming Dynasty continued the Songs economic development. However, when the isolationist Qing Dynasty came into power, Chinas economic development began to slow. Europes rapid development during the Industrial Revolution enabled it to surpass China—an event known as the great divergence. Trade with foreign nations on a large scale began during the reign of Emperor Wu, when he sent the explorer Zhang Yi to contact nations west of China in search of allies to fight the Xiongnu. After the defeat of the Xiongnu, however, Chinese armies established themselves in Central Asia, starting the famed Silk Road, which became a major avenue of international trade Paper and Printing. The greatest Chinese discoveries of all times which the whole world accepts even today are the art of paper making, printing, gun powder and magnetic compass. Paper making was an art which developed in ancient China and they used silk, cloth, bark, fiber and hemp. Later during the Han Dynasty, about 1800 years ago, paper making was refined and was being made from hemp and bark and later from bamboo. Printing technology was invented in ancient China as far back as the 8th century and by 868 they were using wood block printing which was used to print the first book in the world. Advancement in the technology came by 11th century when movable ceramic printer was invented during the rule of the Song Dynasty. By the time the Tang dynasty came to power in ancient China, printing and paper making techniques had prompted the invention of books and book shops in the cities. Compass and Gun Powder. The invention of these two had put ancient China in the fore front in terms of scientific discovery and development. The compass was extremely useful for trade and sea travel. Here they used magnets to magnetize a pointer made of iron. Later the western world borrowed the technique for the navigation on the sea. Gun powder was invented by accident when the ancient Chinese found that throwing some types of mineral powders in the fire produces color and sparkling flame. They used the technology for making fireworks. Later the same gunpowder changed the art of modern warfare when it was used by the European powers against their enemies. Politics and Government. Ancient China had monarchy, i. e. government headed by an emperor and a royal family. Chinese rulers also called monarchs based their government on the Confucian model, which taught that the ruler was a virtuous man who led by example†¦ Despotic leadership. China like many other countries at that time was an agriculture based country with the river Yangtze as its lifeline. During the ancient period the king would be the leader and would be more of a dictator than a king for the people who would take decisions beneficial to them. He has un-surpassing power in all areas be it economy or governance or agriculture which was the livelihood of the people. Earliest incident of despotic leadership could probably be traced back to the Hsia dynasty (2200 – 1750 BC) when the emperor Yao picked Shun as his successor to help his people who were burdened by the regular floods. Enlightened Leadership. Shun can be given credit for being an enlightened leader, but he was very harsh on his people. He could put any of his people to death if they did not agree with his leadership. Other punishments included using whip, stick and fines for small offences. He was succeeded by Yu, who founded Hsia, the first dynasty. During this dynasty the Chinese government or the emperor employed huge labor to work under four groups: military, farming, construction workers and textile labor. Textile labor were given the task of weaving silk thread by hand to make clothes for the royal family, construction work included public work such as building wall, enlarging canals for agriculture etc. Military. Ancient China was most of the time caught in battles against the Huns or the invaders. In military the casualty was very high, because at that time it was quiet common to have mass warfare killing thousands at the same time; ordinary soldiers were simply treated as pawns by the king and other leaders. Shan Dynasty (1750-1040 BC) was ruthless when it came to battles, they even made the whole family fight in battles together because he believed they would fight better with each other. Position of Women. The Shan Dynasty followed the philosophy of Yin and Yan and believed in giving lesser role to women in the society as compared to men. Women were not given opportunities and were treated as inferior. Efforts to reform the Chinese Government. The Chou Dynasty (1040 -256 BC) tried to bring improvements in the government after the corrupt Shan Dynasty and tried to employ the feudal system. This new form of government in ancient China collapsed and ended up with Warring states period (403- 221 BC). Furthermore, corrupt emperors caused the country to fall apart into a continuous war like situation. It was after these that the enlightened Qin Dynasty ruled, which tried to reform and unified the country and builds the Great Wall of China. The Ancient Chinese Government was more of Despotism rather than Enlightened Monarchy which works for the betterment of the people. Legal Systems. Many of the ancient legal systems were considered to be harsh by modern day standards. When societies were beginning to establish civil order and a government hierarchy often many premises seemed extreme; for example, Hammurabi’s Code and the eye for an eye principle or the torture practices common in Medieval Europe. Although, modern China may be suspected of human rights abuses, Ancient China’s legal system was based on morals and the inherent good of the citizens. The Ancient Chinese legal system evolved through the principles of Confucianism and Legalism along with the traditions and morals of Ancient Chinese life. Confucianism. Confucianism as a philosophy gained prominence in the early existence of Ancient China. The Confucian philosophy believed that social control and social order could only be created through education. Confucianism influenced the Ancient Chinese legal system as it believed that humans were inherently good and that order was based on respect for the King and one’s fellow man. The early legal system of Ancient China was as a result, hesitant to utilize codified or written law. This was because codified laws served to tell people what to do without explaining the reasoning. Instead of codified law, the legal system of Ancient China was initially intended to be secondary to moral reasoning. It was believed under Confucianism that by ruling through traditions, norms, and morals that those who broke the accepted conditions would be ashamed and ostracized from society. Over time however, it became clear that in some circumstances people’s self-interest would differ from society. It was because of this that the premises of Confucianism were mixed with those of Legalism to form the first codified law in Ancient China. Legalism. Legalism in contrast to Confucianism was based on the concept that humans were predisposed to evil or wrongdoing. This belief led to the understanding that codified law and punishments were needed in order to maintain order in society. When Ancient China began to incorporate these principles into their legal system a focus was placed on the ruler. It was important to these principles that the ruler remained above the law so that his word could act as a guide. It was also important to Legalism that a ruler was respected so that his laws and punishments were seen as just. As Ancient China’s legal system evolved it remained important that the law had the respect of the people and that the people understood the traditions. Important Principles. Ancient China’s legal system is one of the oldest legal traditions and yet unlike modern day systems there was no separation between civil and criminal law. The legal system of Ancient China was structured around the ruler being able to unify society’s interests while maintaining respect. This premise is why any crimes against the ruler received no mercy. After the ruler in Ancient China the family was held in the highest regard; this is why crimes against the family were considered one of the greatest offences. In general Ancient China’s legal system attempted to enforce filial piety, to uphold the respect of family ancestors, to avoid legal action when possible, to create deterrents to actions and to control outbursts. In comparison, to many other early legal systems, China’s system was relatively relaxed and centered on the citizens rather than government mandates. Ancient China’s legal system was founded on the traditions of the society it was meant to control allowing the system to evolve into the present day Culture. Daily life in Ancient China is as mysterious as it is old. The ancient Chinese were master creators, artists, craftsmen and warlords. They created paper, gunpowder for battles, matches, cannons, compass, umbrellas and many more. They created many artifacts. They developed many martial arts and other art forms such as calligraphy. They used coins with holes in them. As there were no banks at that time they used to collect the money through strings in the coins. Ancient China was ruled by many dynasties and was constantly plagued with war. The peasants celebrated spring which was a very important festival in their life. It was celebrated during spring to welcome a good harvest and good fortune. Usually young men and women paired up and sang and danced. Like today, even in ancient China the Dragon was a sign of good luck. Chinese art is well known throughout the world. Its painting and calligraphy established the guiding principals by which other civilizations would emulate. In Chinese art, each object has its own subjective meaning, and can be interpreted in many ways. To the Chinese, color and form are not just words, but are a part of what makes them a unique people; there ability to surround themselves with beautiful architecture and lavish technique know no bounds. People around the world love Chinese food, and so they should. Lots of tradition and care has gone into some of todays finest and most famous dishes. In addition, Chinese medicine has been around for centuries, but only recently has it become a new, and almost baseline treatment, for common ailments such as headaches and fevers. Ancient Chinese Paintings. There are very few remains of paintings of ancient times except on ceramic and tiles, a clear historic development can be traced only after 5th century AD. Hundreds of caves of Buddhist wall paintings and scrolls dating back to late 5th century AD have been discovered. A highly organized system of representing objects was discovered different from the western perspective; the greatest strength of this art is its incomparable mastery of lines and silhouette. The art of figure painting reached it’s height during the Tang Dynasty, which also saw the rise of the great art of landscape painting executed as brush drawings with color washes Chinese Music and Poetry. Ancient Chinese music can be traced back to Neolithic age based on the discovery of bone flutes. Poetry and Music were influenced by the Book of Song, Confucius and the Chinese poet and statesman Qu Yuan. In the Xia, Shang and Zhou dynasties music was only for the royal families and dignitaries, entering the mainstream only in the Tang Dynasty. In the Song Dynasty ,Kunqu, the oldest form of Chinese opera developed and it was during this time that the writers and artists came up with new form of lyric poetry –Ci. Other Art Forms. There were other forms of art apart from the ones mentioned above during ancient times in China like Seals, Calligraphy, Embroidery, kite making, paper cutting and shadow puppetry. Ancient Chinese culture boasts of glorious forms of Art and traditional crafts which are just two of the many jewels in China’s 5000 year history.

The Strong Nuclear Force | Essay

The Strong Nuclear Force | Essay Youssef El Laithy One of the most extraordinary simplifications in physics is the fact that only four distinct forces are responsible for all the known spectacles that go on in the universe. These four basic forces are the electromagnetic force, the gravitational force, the weak nuclear force and the strong nuclear force. Since the weak and the strong force act over an extremely short range, (less than the size of a nucleus), we do not experience them directly. Even though we don’t directly experience these forces they are vital to our existence. These forces determine whether the nuclei of certain elements will be stable or will deteriorate, and they are the basis of the energy release in many nuclear reactions. The forces determine not only the stability of the nuclei, but also the abundance of elements in nature. The properties of the nucleus of an atom are determined by the number of electrons the atom has. The number of electrons in an atom, therefore, determines the chemistry of the atom. The gravitational force is responsible for holding together the universe at large, the atmosphere, water, and us; humans, to the planet. The electromagnetic force governs the atomic level phenomena, binding electrons their atoms, and atoms to other atoms in order to form molecules and compounds. The weak nuclear force is responsible for certain types of nuclear reactions. The fourth and last force, the strong nuclear force is responsible for holding the nucleus together. The Strong Force is also one of the four fundamental forces of nature, experienced by particles called quarks and sub particles made up of quarks. It is theforce that causes the interaction responsible for binding and holding protons and neutrons together in the atomic nucleus of a given element. The strong force is the strongest of among all the other forces forces, being approximately 100 times as strong as the electromagneticforce. It has the extremely short range to which it has an effect. A range of approximately 10^-15 m, less than the size of the atomic nucleus. The strong force is carried by particles called gluons; that is, when particles interact through the strong force, they do so by exchanging gluons. The protons in a nucleus must experience a repulsive force from the other protons in the nucleus.This is where the strong nuclear force comes into play. The strong nuclear force is created between the nucleons (protons and neutrons) by the exchange of particles called mes ons. This exchange can be compared to constantly hitting a tennis ball or a footballback and forth between two people. As long as these particles (mesons) are in motion back and forth, the strong force is able to hold the participating nucleons together. Thenucleons, however; mustbe extremely close to each other in order for this exchange of mesons to occur. The distance requiredfor the force to take place and have an effectis roughly about the diameter of a proton or a neutron. Thus, if a proton or neutron can get closer than this distance to proton on neutron, the exchange of mesons occurs normally and the force has an effect. However,if they cant get that close, the strong force is too weak to make them bind together and thus the force won’t have an effect and the nucleus would rapture. The range of the Strong Force varies from where it takes place. The strong interaction is apparent in two areas: On a large scale (about 1 to 3 femtometers ), it is the force that binds protons and neutrons (nucleons) together to form the nucleus of an atom . On a smaller scale (less than about 0.8 femtometers, the radius of a nucleon), it is the force (carried by gluons ) that holdsquarkstogether to form protons, neutrons, and other hadron particles. The discovery of the Strong of the nuclear force was a remarkable discovery and cleared up lots of mysteries that haunted many physicists in this era. The discovery force wasn’t all at once; meaning that the discovery was based on the work of more than once scientist and physicist all over the years. The first discovery was by James Chadwick. In 1932, British physicist James discovered that the nucleus of atoms contain neutrons. Soon after this discovery, the American-Hungarian physicist, Eugene Wigner suggested that the electromagnetic force wasn’t the force responsible forholding the nucleus together and he also suggested that there are two different nuclear forces not just one.Later on,In 1935 Japanese Yukawa Hideki reasoned that since the strong nuclear force and weak nuclear force had never been noticedor observed by the bare eye or even by microscopesthey must act over a range smaller than the diameter of the atomic nucleus.Yukawa developed the first field theory ofthe strong force with a new particle he called mesons as the force carryingsimulated particle. From these facts and hypothesizes, Hideki Yukawa concluded that there exists a force that binds nucleons (protons and neutrons) together. He named the force the â€Å"strong nuclear force† because it had to be stronger than the electromagnetic force that would otherwise push the nucleons apart. In everyday life and our day to day life, were only aware of two fundamental forces: gravity and electromagnetism. Physicists know about two more forces, which are carried out within the atom itself (inside atoms): the strong nuclear force and the weak nuclear force.Try and imaginetwo protons (positive charge), they are pulled together by the strong nuclear force (as long as they are within range to start with). But the electromagnetic force pushes them away from each other, because they both have the same positive electric charge. When we talk about the uses if the strong nuclear force we can’t really find a direct use in which humans use the force. The only direct use is that the binding energyrelated to the strong nuclear force is used innuclear powerandnuclear weapons. The strong nuclear force is crucial to our everyday survival, God created this force exactly to suit our survival. Following this notion two questions are raised: What would happen if the strong nuclear force were a bit weaker? If the strong force were even slightly weaker than what it is, it would not be able to hold the atomic nuclei together against the repulsion of the electromagnetic force. According to Barrow and Tipler: `Ifthe Strong Force was decreased by 50% its normal power thiswould adversely affect the stability of all the elements essential to living organisms and biological systems. A bit more of a decrease, and there wouldntbe any stable elements except hydrogen. What would happen if the strong nuclear force were a bit stronger that what it is? According to Borrow and Tipler: â€Å"If the strong nuclear force was just a bit stronger compared to the electromagnetic force, two protons could stick togetherdisregardof their electromagnetic repulsion (forming a diproton).If this happened, all the hydrogen in the universe would have been burned to helium. If there were no Hydrogen in the universethere would be no water, for a start, and there would be no long-lived stars like the sun. (Stars made from helium burn up much more quickly than stars made from hydrogen).† In conclusion, The Strong Nuclear force is one of the four fundamental forces found in nature. The strong nuclear force is responsible for holding the neutrons and protons in the atomic nucleus. The interactions are experienced only by particles called quarks and by elementary particles made from quarks (mesons, gluons). The discovery of the strong nuclear force was possible by the collective work of many physicists over many years. The strong force isn’t of that much of direct use for humans. However, the force is crucial to our everyday life. If the strong nuclear force was slightly even weaker than it is, all the chemical elements needed for life would not be stable, and we, humans, would not seize to exist. The strong force isnt of that much of direct use for humans. However, the force is crucial to our everyday life. Ifthe strong nuclear force was weaker than it is, the chemical elements needed for life wouldn’t be stable, and we would not be here. On the other han d, if it were even slightly stronger than it is, all the hydrogen in the universe would have been burned in the big bang. As a result, there would be no prolonged stars like the sun, and no molecules like water. There would probably be no complex chemistry in the universe, and we would not seize to exist.

The international system today is an interplay of national power of different nations. This can be felt in the emerging world order. There has been a perceptible change, particularly during the last two decades, in the manner the nation states conduct international relations. Military alliances have given way to multilateral groupings, understandings and strategic partnerships. Nations are becoming increasingly aware of the power or influence that they wield vis-à  -vis other nations.  [1]   They are also looking at the ways and means to use this national power to secure their vital interests. In the later part of last century, National Power was only considered to be military power as can be understood by the superpower status of Soviet Union. But the disintegration of the Soviet empire and changing face of world relations due to economic globalization changed the world perception and brought the term Comprehensive National Power. This term was more inclusive of the overall state of the affairs of a nation and a measure of its constituents could indicate the strength and weaknesses.  [2]   National Power has tangible and intangible elements. Geography, natural resources, industrial capacity, population, military power form the tangible parts while national character and morale complete the intangibles. Indias economy has contributed in the last two decades towards a major share of the National power. In fact, India has even demonstrated certain soft power by cooption and attraction of other nations to achieve some of its aims. The primary currencies of soft power are an actors values, culture, policies and institutions. Indias soft power is based on its social and cultural values, the Indian Diaspora abroad and its knowledge base. India is being considered a knowledge superpower and is well placed to leverage its position in international relations. However, the military has also contributed towards the soft power. A well-run military has been a source of attraction, and military-to-military cooperation and training programmes, for example, have established transnation al networks that enhance countrys soft power. METHODOLOGY Statement of Problem The growth notwithstanding, India cannot afford to be satisfied with its current status. The geopolitical situation in the region is unstable. Though Pakistan has fewer options left after it has been exposed as a hub of terror activities and a haven for wanted terrorists, still if cornered by the world pressure and the internal compulsions it will not think twice in a military option against India to divert the attention and bring in its all weather friend , China, into the picture. India can achieve its national aims only if the internal and external threats to its security is ensured. This situation can be understood with an analogy to game of soccer; a team may be having the best of strikers in their forward and midfielder players, who can score goals at will, but their efforts are inconsequential if the goalkeeper is not trained and equipped to save goals from adversary. Thus, in the changing geopolitical situation, it is pertinent to evaluate the share of constituents of National Power to ascertain the future dynamics of a nations aspirations and interests and the regional environment. India has already made tremendous progress in various fields to achieve soft power constituent to contribute towards National Power. Indian economy is showing positive growth and attracting strategic partnership with leading economies around the globe.India , now needs to develop the military constituent to further pursue its National aim. Hypothesis India needs to develop a potent Military capability by the year 2025 to be able to assert its National Power in keeping with the stated National objectives. Methods of Data Collection 9. The data for this dissertation has been collected from a large number of books, periodicals, magazines, newspapers, internet and research journals that are available in the Defence Services Staff College library. The data related to Indian Military Power has been collected from open sources only so as to avoid any classified information to be brought out. The Bibliography is attached as Appendix. Organisation of the Dissertation Apart from a chapter on the introduction and methodology, the dissertation has been organized under the following chapters:- CHAPTER 2. CONSTITUENTS OF INDIAN NATIONAL POWER Section 1. National Power. Section 2. Indias National Power. Section 3. Constituents Of Indian National Power. CHAPTER 3. MILITARY POWER Section 1. Elements of Military Power. Section 2. Present State Of Indian Defence Forces. Section 3. Defence Budget And Modernisation Program. CHAPTER 4. SHORTCOMINGS OF INDIAS MILITARY POWER Section 1.

The present Indian standing in the world order is based on the soft power developed and the economic growth achieved by India. India as rising economy, offers excellent investment opportunity to the world. The democratic form of governance also projects India as stable and secure investment site in the long run. However we need to examine the constituents and their present share towards National Power. Chapter 3- Military Power. It itself comprises the tangibles and the intangibles. It can be broadly categorized in force capability and force employment. There has been a change in war fighting. The technological advancement ,weapon lethality, destructiveness and precision along with the information frontier has increased the cost factor of going to war. Thus there is a need to analyse the military power constituents to understand the importance towards national Power. Chapter 4- Analysis and Short comings of Indian Military Power. To suggest steps towards projecting a stronger military power the present capability needs to be analysed and the shortcoming to be highlighted. Chapter 5- Desired National Power by 2025. The regional environment in the near future entails proactive approach by India to project comprehensive national power to have secured borders and assured growth to achieve its national aims . CHAPTER 2 CONSTITUENTS OF NATIONAL POWER National Power 1. The international system today.is an interplay of national power of different nations. There has been a perceptible change.in the manner the nation states conduct International relations. Military alliances have given way to multilateral groupings, understandings and strategic partnerships. Nations are becoming increasingly.aware of the power or influence that they weild.vis-à  -vis other nations. 2. During 1960 and 70s most theorists.doing research on international relations avoided dealing.with phenomenon of power. National power was considered synonymous.with military power. This would explain to a great extent the superpower status.of erstwhile Soviet Union and its unexpected disintegration. Since then perception of national power.has undergone a change. It is called as comprehensive National power by the theorists which is a more inclusive term comprising all the facets of a nations resources which contribute towards its security. Defining National Power 3. National power is the ability of a nation with the use of which.it can get its will obeyed by other nations. It involves the capacity to use force.or threat of use of force over other nations. With the use of national power, a nation is able to control.the behavior of other nations in accordance with its own will. In other words, it denotes the ability of a nation.to fulfill its national goals. It also tells us how much powerful or weak.a particular nation is in securing its national goals. Basic Elements Of National Power 4. The basic elements of national power include diplomacy, economics, informational, soft power and the age old trustworthy element of military power. It can also be classified as comprising of tangible elements and intangible elements. Geography, natural resources, industrial capacities, population, military power form the tangible elements of national power and national character and morale complete the intangibles. Indias National Power 5. In international politics, the image of India till recently used to be in terms.of its perennial rivalry with Pakistan and as power confined to South Asia only. However, as result of the remarkable improvement.in Indias national strength over the last decade, consisting of.its hard and soft powers, the world has started rehyphenating India.with a rapidly growing China. The term rising India is a buzzword in the International Relations discourse nowadays. Indias national power has begun to rise steadily.since Pokhran-II. India unleashed a slew of path-breaking initiatives.in quick succession in 1998 (and beyond). It was from this year onwards that the idea of India being a great power,.first floated by Nehru, started to be reflected in its foreign policy. Admittedly, India shifted its foreign and economic policies.soon after the end of the Cold War in 1991 when it started broadbasing.its diplomacy, initiated economic reforms by dismantling the economic model.based on import substit ution, and went for market friendly policies. The economic reforms did give India economic stability.in the sense that India started growing at 6% annually.ever since the economic liberalization of early 1990s, however, political stability remained fragile. The country got much-needed political stability.at the center in March 1998 and a series of radical initiatives in quick succession beginning with the nuclear tests in the Pokhran desert of Rajasthan on May 11th and 13th 1998, was a grand strategic masterstroke by independent India. India initiated Multi-aligned/Great power diplomacy.for the first time in its independent history when it developed strategic partnerships.with all the great powers simultaneously, especially its relations with the United States and Japan, while retaining time-tested ties with Russia. India made institutional arrangements to its national security.when it set up the National Security.Advisory Board, National Security.Council, Nuclear Command Authority, developed a.nuclear doctrine, and so on. 6. More importantly, India developed a much needed strategic vision.whereby it redefined its geo-strategic.construct well beyond the mainland of South Asia. The comprehensive geo-strategic.construct included the Indian Ocean, the Middle East, Central Asia and the Asia-Pacific. In fact, the 1998 nuclear tests themselves were indicative of the fact that India had begun to appreciate the role of hard power in securing its national interests and also in making her influence heard in international politics. 7. The India, that China defeated.in 1962 was guided by a foreign policy canon of non-alignment.vis -à  -vis the superpower enmity, and it remained the cornerstone of Indias international.diplomacy for more than four decades. However, this foreign policy paradigm underwent.a U-turn when it metamorphosed into poly/multi-alignment under the new leadership.in New Delhi in 1998. The new foreign policy outlook.broadly had two components, namely, improving relations with the US and its Look East Policy-II. The turnaround in India-US relations from being estranged democracies during the Cold War to engaged democracies in the 2000s has played a central role in bringing out a shift in Chinas India posture over the last decade. India has been a democracy right since its birth as a modern nation-state in 1947. However, its sluggish economic growth and weak military profile that led to its defeat in 1962 seriously stained this aspect of Indias soft power. 8. With the rising India story, its democracy as an important component of its soft power has again come into the global limelight. India has more than 1 billion people. It is linguistically, culturally, racially, and religiously diverse, and it is growing economically at an enviable pace under democratic governmental institutions (except for the emergency period of 1975-77 when civil liberties were undermined). Its culture values peaceful coexistence, nonviolence, and religious tolerance. All of these factors, combined with the largest pool of English speakers outside the US, has increased Indias power of attraction without need for coercion or persuasion, a fact not lost on an envious, hard power-minded China. The country to which India has projected most of its soft power is the US, through the export of highly skilled manpower, consisting mainly of software developers, engineers, and doctors. 9. In military terms, post-1998 India has been enjoying strategic capital, in the sense that, unlike the rise of China, Indias military rise is not only not feared but it is felt to be desirable by the countries in the Asia-Pacific like Japan, Australia, South Korea, and ASEAN as a group. Most importantly even the US sees Indias military rise in its own interests.28 Interestingly, a rising India is making full use of this capital by emerging as a formidable military power over the last decade, apart from unveiling even more ambitious military plans for the future CHAPTER 3 MILITARY POWER Military Power 1. Military Power is military dimension of national power. National power embodies soft persuasive or attractive elements as well as its hard or military component. Military power can itself mean different things in different contexts; as military forces do different things ranging from defending national territory to invading other states; countering terrorists or insurgents, keeping the peace, enforcing economic sanctions, maintain domestic order. Proficiency in one task does not entail proficiency in all as good defenders of national territory can make poor peacekeepers and also may not be able to conquer neighbours. 2. Since beginning of civilization, military power has been the primary instruement nation states have used to control and dominate each other. With the growth of technology, the destructiveness of military power has reached apocalyptic proportions. 3. Throughout history, military power has been paramount and economic power a luxury. This has slowly changed to the point that the two roles have been reversed. Japan, China have relied on economic prosperity to finance formidable military forces. Conversely, erstwhile Soviet Union, Iraq and North Korea have relied on their military to build economic power with little or limited success. 4. Military power is the capacity to use force or threat of force to influence other states. Components of military power for a nation include number of military formations, armaments, organization, training, equipment, readiness, deployment and morale. Elements of Military Power 5. Elements of military power are worked out on the basis of military capability of nations. It includes numerical preponderance, technology and force employment. . Numerical preponderance has been exemplified in yesteryears; Napolean said , God is on the side of the big battalion 6. It is generally believed that states with larger population, more developed economies, larger military should prevail in battle. This is association of victory with material preponderance and beneath this lies the widespread perception that economic strength is precondition for military strength; that economic decline leads to military weakness and that economic policies merit co equal treatment with political and military considerations in national strategy making. Military preparedness requires a military (establishment) capable of supporting the foreign policy of a nation. Contributory factors are technology,leadership, quality and size of the armed forces. (a) Technology. The development and adoption of firearms, tanks, guns and aircraft have had a profound effect on the course of battles. To illustrate, if one reads the review of British operations during the initial stages of the Second World War, which Churchill gave in the secret session of parliament on 23 April 1942,one is struck by the fact that all defeats on land, on sea and in air have one common denominator-the disregard of technological capabilities being developed by Germans and the Japanese during the pre-war years. The U-boats played havoc with the British shipping and adversely affected their ability to move forces from one theatre of war to another, as also to sustain them. Conversely, the development of radar technology by the British during the war years gave them enormous advantage over their enemies. In the present-day context, capabilities in cyber warfare, space assets and smart strike weapons will give a great edge to the powers that are able to develop and operationalise such technologies. (b) Leadership. The quality of military leadership has always exerted a decisive influence upon national power. We have the examples of the military genius of Fredrick the Great, Napoleon, the futility of Maginot Line psychology of the French General Staff versus the blitzkrieg adopted by the German General Staff, and closer home the effect of superior military leadership led by Field Marshal SHFJ Manekshaw in Indias 1971 War with Pakistan. (c) Quality and Size of the Armed Forces. The importance of this factor is obvious. However, the question that has to be answered by the political leadership of the country is, how large a military establishment can a nation afford in view of its resources and commitments or national interests? CHAPTER 4 SHORTCOMINGS OF INDIAN MILITARY POWER Much has been written and said about the potential for Indian military power to play a greater role on the world stage, and perhaps check Chinas expanding capabilities in the future.National Security has attained multi-faceted dimensions with wider challenges in diverse fields.There has been growing understandings of these challenges and consequently measures are being taken to overcome the same. Indias remarkable economic growth and newfound access to arms from abroad have raised the prospect of a major rearmament of the country. But without several policy and organizational changes, Indias efforts to modernize its armed forces will not alter the countrys ability to deal with critical security threats. Indias military modernization needs a transparent, legitimate and efficient procurement process. Further, a chief of defense staff could reconcile the competing priorities across the three military services. Finally, Indias defense research agencies need to be subjected to greater ove rsight. Indias rapid economic growth and newfound access to military technology, especially by way of its rapprochement with the United States, have raised hopes of a military revival in the country. Against this optimism about the rise of Indian military power stands the reality that India has not been able to alter its military-strategic position despite being one of the worlds largest importers of advanced conventional weapons for three decades. Civil-military relations in India have focused too heavily on one side of the problem how to ensure civilian control over the armed forces, while neglecting the other how to build and field an effective military force. This imbalance in civil-military relations has caused military modernization and reforms to suffer from a lack of political guidance, disunity of purpose and effort and material and intellectual corruption. The Effects of Strategic Restraint Sixty years after embarking on a rivalry with Pakistan, India has not been able to alter its strategic relationship with a country less than one-fifth its size. Indias many counterinsurgencies have lasted twenty years on an average, double the worldwide average. Since the 1998 nuclear tests, reports of a growing missile gap with Pakistan have called into question the quality of Indias nuclear deterrent. The high point of Indian military history the liberation of Bangladesh in 1971- therefore, stands in sharp contrast to the persistent inability of the country to raise effective military forces. No factor more accounts for the haphazard nature of Indian military modernization than the lack of political leadership on defense, stemming from the doctrine of strategic restraint. Key political leaders rejected the use of force as an instrument of politics in favor of a policy of strategic restraint that minimized the importance of the military. The Government of India held to its strong anti-militarism despite the reality of conflict and war that followed independence. Much has been made of the downgrading of the service chiefs in the protocol rank, but of greater consequence was the elevation of military science and research as essential to the long-term defense of India over the armed forces themselves. Nehru invited British physicist P.M.S. Blackett to examine the relationship between science and defense. Blackett came back with a report that called for capping Indian defense spending at 2 percent of GDP and limited military modernization. He also recommended state funding and ownership of military research laboratories and established his protà ©gà ©, Daulat Singh Kothari, as the head of the labs. Indian defense spending decreased during the 1950s. Of the three services, the Indian Navy received greater attention with negotiations for the acquisition of Indias first aircraft carrier. The Indian Air Force acquired World War II surplus Canberra transport. The Indian Army, the biggest service by a wide margin, went to Congo on a UN peacekeeping mission, but was neglected overall. India had its first defense procurement scandal when buying old jeeps and experienced its first civil-military crisis when an army chief threatened to resign protesting political interference in military matters. The decade culminated in the governments forward policy against China, which Nehru foisted on an unprepared army, and led to the war of 1962 with China that ended in a humiliating Indian defeat. The foremost lesson of 1962 was that India could not afford further military retrenchment. The Indian government launched a significant military expansion program that doubled the size of the army and raised a fighting air force. With the focus shifting North, the Indian Navy received less attention. A less recognized lesson of the war was that political interference in military matters ought to be limited. The military and especially the army asked for and received operational and institutional autonomy, a fact most visible in the wars of 1965 and 1971. The problem, however, was that the political leadership did not suddenly become more comfortable with the military as an institution; they remained wary of the possibility of a coup detat and militarism more generally. The Indian civil-military relations landscape has changed marginally since. In the eighties, there was a degree of political-military confluence in the Rajiv Gandhi government: Rajiv appointed a military buff, Arun Singh, as the minister of state for defense. At the same time, Krishnaswami Sundarji, an exceptional officer, became the army chief. Together they launched an ambitious program of military modernization in response to Pakistani rearmament and nuclearization. Pakistans nuclearization allowed that country to escalate the subconventional conflict in Kashmir while stemming Indian ability to escalate to a general war, where it had superiority. India is yet to emerge from this stability-instability paradox. The puzzle of Brasstacks stands in a line of similar decisions. In 1971, India did not push the advantage of its victory in the eastern theatre to the West. Instead, New Delhi, underuberrealist Prime Minister Indira Gandhi, signed on to an equivocal agreement at Simla that committed both sides to peaceful resolution of future disputes without any enforcement measures. Indias decision to wait 24 years between its first nuclear test in 1974 and the second set of tests in 1998 is equally puzzling. Why did it not follow through after the 1974 test, and why did it test in 1998? Underlying these puzzles is a remarkable preference for strategic restraint. Indian leaders simply have not seen the use of force as a useful instrument of politics. This foundation of ambivalence informs Indian defense policy, and consequently its military modernization and reform efforts. To be sure, military restraint in a region as volatile as South Asia is wise and has helped persuade the great powers to accommodate Indias rise, but it does not help military planning. Together with the separation of the armed forces from the government, divisions among the services and between the services and other related agencies, and the inability of the military to seek formal support for policies it deems important, Indias strategic restraint has served to deny political guidance to the efforts of the armed forces to modernize. As wise as strategic restraint may be, Pakistan, Indias primary rival, hardly believes it to be true. Islamabad prepares as if India were an aggressive power and this has a real impact on Indias security. Domestic And Regional Constraints India faces several daunting domestic and border challenges within its own neighborhood that may prevent it from thinking more globally including the unresolved issue of Kashmir, an increasingly grave Maoist threat, Islamic terrorism from Pakistan, and unresolved border issues with China which broke out in war in 1962. Beijings effort to beef up its presence in South Asia is also seen as challenging Indian dominance there. The Lack of Strategy Indias military modernization remains, and likely will continue to be, an a-strategic pursuit of new technology with little vision. There is a whole host of problems that the nation faces, including: Little political guidance from the civilian leadership to the military. This is true even on the general issue of what Indias major goals should be. Even the Indian navy, which is often assumed to be the most forward thinking institution within Indias military, does not see itself as more than a naval blockade vis-à  -vis Pakistan. Lack of organizational and institutional reforms. The need to reprioritize resources is never addressed, what is addressed is the procurement of new material, thus making modernization merely an exercise in linear expansion. No legitimate and transparent procurement system. As a result, purchases are often ridden with scandals, corrupt, delayed and highly politicized. Indias Defense Research and Development Organization (DRDO) is also a failed organization that is ideologically corrupt, but there has not been an honest attempt to put it under public scrutiny. Imbalance in Civil-Military Relations What suffices for a military modernization plan is a wish list of weapon systems amounting to as much as $100 billion from the three services and hollow announcements of coming breakthroughs from the Defense Research and Development Organization (DRDO), the premier agency for military research in India. The process is illustrative. The armed forces propose to acquire certain weapon systems. The political leadership and the civilian bureaucracy, especially the Ministry of Finance, react to these requests, agreeing on some and rejecting others. A number of dysfunctions ensue. First, the services see things differently and their plans are essentially uncoordinated. Coming off the experience of the Kargil war and Operation Parakram, the Indian Army seems to have arrived at a Cold Start doctrine, seeking to find some fighting space between subconventional conflict and nuclear exchange in the standoff with Pakistan. The doctrine may not be official policy, but it informs the armys wish list, where attack helicopters, tanks and long-range artillery stand out as marquee items. The Indian Air Force (IAF), meanwhile, is the primary instrument of the countrys nuclear deterrent. The IAFs close second role is air superiority and air defense. Close air support, to which the IAF has belatedly agreed and which is essential to the armys Cold Start doctrine, is a distant fourth. The Indian Navy wants to secure the countrys sea-lanes of communications, protect its energy supplies and guard its trade routes. It wants further to be the vehicle of Indian naval diplomacy and sees a role in the anti-piracy efforts in the Malacca Straits and the Horn of Africa. What is less clear is how the Indian Navy might contribute in the event of a war with Pakistan. The navy would like simply to brush past the problem of Pakistan and reach for the grander projects. Accordingly, the Indian Navys biggest procurement order is a retrofitted aircraft carrier from Russia. Indias three services have dramatically different views of what their role in Indias security should be, and there is no political effort to ensure this coordination. Cold Start remains an iffy proposition. Indias nuclear deterrent remains tethered to a single delivery system: fighter aircraft. Meanwhile, the Indian Armys energies are dissipated with counterinsurgency duties, which might increase manifold if the army is told to fight the rising leftist insurgency, the Naxalites. And all this at a time when the primary security threat to the country has been terrorism. After the Mumbai attacks, the Indian government and the people of India are said to have resolved to tackle the problem headlong, but today the governments minister in charge of internal security, Palaniappan Chidambaram, is more under siege himself than seizing the hidden enemy. Second, despite repeated calls for and commissions into reforms in the higher defense structure, planning, intelligence, defense production and procurement, the Indian national security establishment remains fragmented and uncoordinated. The government and armed forces have succeeded in reforms primed by additions to the defense budget but failed to institute reforms that require changes in organization and priorities. The Kargil Review Committee, and the Group of Ministers report that followed, for example, recommended a slew of reforms. The changes most readily implemented were those that created new commands, agencies and task forces, essentially linear expansion backed by new budgetary allocations. The changes least likely to occur were those required changes in the hierarchy. The most common example of tough reform is the long-standing recommendation for a chief of defense staff. A military chief, as opposed to the service chiefs, could be a solution to the problem that causes the three services not to reconcile their pr Gas Sensing Properties of Te Thin Films: Thickness and UV Gas Sensing Properties of Te Thin Films: Thickness and UV Thickness and UV irradiation effects on the gas sensing properties of Te thin films Abstract In this research, tellurium thin films were investigated for use as hydrogen sulfide gas sensors. To this end, a tellurium thin film has been deposited on Al2o3  substrates by thermal evaporation, and the influence of thickness on the sensitivity of the tellurium thin film for measuring H2S gas is studied. X-ray diffraction (XRD) analysis, scanning electron microscope(SEM) and Raman Spectrometer were utilized for characterizing the prepared samples. XRD patterns indicate that as the thickness increases, the crystallization improves. Observing the images obtained by SEM,  it  is  seen  that the grain size increases as the thickness increases, and consequently, fewer defects will be seen in the surface of the film. Studying the effect of thickness on H2S gas measurement, it became obvious that as the thickness increases, the sensitivity decreases and the response and recovery time increases. Studying the thermal influence of the thin film while measuring H2S gas,  it become s obvious  that as the detection temperature of the thin film increases, sensitivity and the response and recovery times reduce. To improve the response and recovery time of the tellurium thin film for measuring H2S gas, the influence of UV radiation while measuring H2S gas was also investigated. The results indicate that the response and recovery times strongly decrease  using UV radiation. Introduction Tellurium is a P type semiconductor with narrow band gap and a gap energy of 0.35eV which makes it ideal for use in thin film transistors [1], gas sensors [2-4], optical information storage [5] and shields in passive radiative cooling [6]. Recently, it has been shown that the tellurium thin film is sensitive to some toxic gases like H2S [7]. Hydrogen sulfide is a toxic and corrosive gas which is formed in coal mines, oil and gas industries, chemical products plants, and the sewers. Exposure to small amounts of this gas (less 50 ppm) causes headache, poor memory, loss of appetite and irritability, while exposure to large amounts (most of 500 ppm) will cause death after 30-60 minutes [8]. So far, various semiconductor metal oxides have been  produced  for detecting H2S gas such as SnO2, WO3, and CeO2  [9-11]. The main problem of these sensors is that they  require high temperature for measuring H2S gas, and this high temperature will shorten the life of the sensor[12]. Measurin g gas through semiconductor metal oxide depends upon parameters like thickness of the thin film, deposition temperature, and the substrate  material. So far, few reports have been issued about the sensitivity of the tellurium thin film to some reducing and oxidizing gases such as NO2, CO, NH3, and H2S [4,7,13,14]. In this research, the influence of the thickness of the tellurium thin film on detecting H2S gas and also the influence of the film temperature and UV radiation while measuring H2S gas have been studied. Experiment details Tellurium thin films with thicknesses of 100, 200, and 300 nm measured by Quartz digital thickness gauge, were deposited on Al2O3  substrate by thermal evaporation of pure tellurium in a tungsten crucible. Substrates were cleaned for 30 minutes by alcohol and acetone in ultrasonic bath. The initial pressure of the vacuum chamber and the temperature of substrate while depositing were respectively 3Ãâ€"10-5  mbar and 373K. The growth rate of the film and the deposition area were respectively 5nm/s and 100mm2. Gold electrodes were deposited on the surface of film through thermal evaporation and copper wires were attached to them by silver paste. The microstructure of the films was characterized through X-ray diffraction (XRD). The morphology of the films surface was determined by scanning electron microscope (SEM). Sensor response to various concentration of H2S gas was studied in a container made of stainless steel with a volume of 250cm3  .The electrical resistance of the senso rs was measured by a multimeter as a function of time. Gas limit  detection was performed for the films with different thicknesses and at different environment temperatures. The sensors were also exposed to UV radiation while detecting H2S gas. The mechanism of gas detection was investigated by Raman spectroscopy technique. The spectra were recorded before and after exposure to the gas. Raman spectra of the films were recorded in back scattering geometry with a spectral resolution of 3 cm-1. The 785 nm line of Ar+  laser was used  for excitation. Results and Discussion XRD patterns of tellurium films with different thicknesses are shown in fig. 1. In this figure, the peaks  denoted  with star are related to Al2O3  substrate. At 100 nm,  Te thickness peak of low intensity is observed at 27.77 °Ã‚  which is related to Te (101) with hexagonal structure. At 200 nm, in addition to Te (101), another peak corresponding to Te (100) appears at 23.15 °. Finally, besides Te (100) and Te (101), a new peak is observed at 40.78 °which is related to Te (110) with hexagonal structure. From the XRD results, it can be inferred that, thickness increases  the  results in an increase of film crystallinity due to the increase of the number of planes that generate diffraction. Fig. 2 shows the SEM images of prepared Te films at different  thicknesses.  [S1]At 100 nm, the grains are separated from each other  by a  large distance, thereby forming discontinuous and rough surface. Increasing film thickness leads to an increase of surface homogeneit y and continuity, grain size increase  as well. Fig. 3 depicts the resistance variation of the tellurium thin films with different thicknesses at room temperature before exposure to H2S gas. It can be seen that the film resistance decrease with thickness increase due to reduction of irregularity in grain arrangement and inhomogeneity on  the  film surface,  which leads to a better charge carrier mobility. The sensitivity of the films to H2S is given by: S=   Where Ra  and Rg  are the electrical resistance of the film in the air and the H2S respectively. Fig. 4 shows the effect of Te film thickness on sensitivity to 8ppm of H2S at room temperature.  Note that the film sensitivity decreases  with  an increase in  thickness. To explain this behavior, it is worth mentioning that the proposed mechanism for H2S gas measurement is as follows: the oxygen in the air is adsorbed by the film surface, especially in the grain boundaries and film porosities. After adsorption, oxygen reacts with Te film surface and based on the film temperature, it can be ionized into O2, O2-, O  (in the temperatures less than 150CËÅ ¡ the ionization form is O2). These forms of oxygen ionization increase the film hole density which means  a reduction of Ra  in P type semiconductor such as Te. As H2S gas is added, it reacts with ionized oxygen  and the result will be  the  return of electrons inside the film and reduction of the hole numbers and increase of Rg  resistance. The reactions are shown below: O2(gas) O2(ads)(1) O2(ads)+ e O2(ads)(2) H2S(gas)+O2(ads) H2(gas)+SO2(gas)+ e(3) At 100 nm Te thickness, the presence of a high density of grain boundaries and defects results in a high H2S gas adsorption which causes noticeable variations in film electrical resistance,  indicating an increase of sensitivity. At higher thickness, where the grain boundary and defects densities decrease,  the changes in resistance are intangible involving a decrease in the sensitivity as shown in fig. 4. The other important characteristic of sensor is its selectivity. The sensitivity on exposure to 10 ppm of CO, NH3  and NO was found to be 3 %,40 % and -67 % (negative sign indicates reduction in resistance), respectively[]. Thus we see that the Te films have much larger sensitivity towards H2S gas in comparison to other gases. Fig. 5 shows the response kinetics of Te films at different thickness (100 nm and 200 nm) after exposure to 8ppm H2S. Considering the response and recovery times, the times for reaching 90% of steady-state values of Ra  and Rg  respectively  can b e defined. It can be clearly seen in fig. 5 that thickness increase leads to an increase of response and recovery times. The former and the latter are due to high adsorption rate of H2S and O2  gases, respectively, at 100 nm by the great numbers of grain boundaries and defects [15]. Fig. 6 shows Raman spectra of 100 nm Te sample before and after exposure to 8 ppm H2S gas at room temperature. In both spectra, peaks at 123, 143 and 267 cm-1  are related to tellurium. Two other peaks  observed in sample before inducing H2S gas  at 680 and 811 cm-1  are assigned to TeO2  [16].  Notice that the intensity of oxide phase is much less than that of Te phase indicating that a low fraction of Te film is oxidized,  which  is  due to Te atoms on the surface [17]. After exposure to H2S gas,  based on  the proposed  reaction mechanism  the TeO2  peaks have almost disappeared. In addition, no peak corresponding to H2S or compounds of sulfur or hydrogen is detected in f ilm after exposure to H2S gas. Fig. 7 shows the sensors sensitivity as a function of H2S gas concentration for 100, 200 and 300 nm samples at room temperature. The film to 100 nm Te thickness presents a linear response from  the  8 to 34 ppm range and the film sensitivity seems to saturate at higher concentration. As expected, from fig. 7  it can be seen  that the sensitivity decreases as the film thickness is increased. Figure 8 shows the results related to response and recovery time for all samples  while being exposed to various concentrations  of H2S gas  at  room temperature. Studying the results  it is  clear  that as the H2S gas concentration increases, the response time decreases and the recovery time increases.  This  is because as H2S gas concentration increases, the probability of a reaction between gas and ionized oxygen becomes more probable, and more reactions  will be observed  in a shorter time which causes the resistance to change faste r and finally reach a constant level. As the concentration goes up, more H2S gas molecules are absorbed and their desorption requires a longer time. The resistance of different samples as a function of detection temperature before exposure to H2S gas  is shown in fig. 9. In all thickness, a decrease of resistivity is observed with temperature increase due to electrical properties of semiconductor, as well as increase of oxidation reaction rate. In the case  of  300 nm Te films the variation of resistance is insignificant because of  the  very low resistance of this sample. Fig.  10 shows the results related to sensitivity as a function of temperature while being exposed to 8ppm of H2S gas. Investigating the results,  it is found that temperature rise leads to reductions in  sensitivity in all samples, because the number of charge carriers in samples increases as  the  temperature rises and as a result, when samples are exposed to H2S gas, no tangible resistance c hange is observed and sensitivity decreases [18]. In samples with 300nm thickness and with temperatures above 90C °Ã‚  there is no sensitivity against H2S gas,  since the number of charge carriers is so  high  that their change is never tangible by reaction with H2S gas. Fig. 11 shows the recovery and response times as a function of temperature while being exposed  to  8 ppm H2S gas. In all samples,  as the temperature rises the response and recovery time decreases. Overall, two factors are effective for a reaction: first, the molecules which are going to take part in the reaction must have a lot of energy, second, they must collide with one another in an appropriate direction. Temperature rise causes an increase in energy and more effective collisions will take place between reactants, and the response and recovery time decrease. To study the effect of UV irradiation on the sensor properties during the gas detection, samples are simultaneously exposed to 8 ppm H2S gas and UV radiation  at  room temperature. Fig. 12 shows a comparison between the sensor sensitivity of the UV exposed  and unexposed cases as a function of Te film thickness. It is obvious that application of UV radiation results in a dramatic reduction of sensors sensitivity. As it is well-know, UV radiation creates supplementary charge carriers by an excess of electron-hole pairs formation.  Increase of charge carriers number  involves a decrease of resistance such that the changes of resistance  are  not tangible while reacting with H2S gas. Fig. 13 presents the recovery and response times as a function of H2S gas concentration before and after exposure to UV radiation.  It is observed  that the recovery and response times strongly depend on UV radiation. These two parameters decrease with UV radiation due to creation of electron-hole pairs. The created electrons react with adsorbed oxygen, so the number of ionized oxygen reacting with H2S gas increase, which can result in an increase of reaction rate between oxygen and H2S gas. The above explanations can be summarized in the following reactions: O2(gas) O2(ads)(4) O2(ads) + e O2(ads)(5) hÃŽ ½ e + h O2  (ads)+ e 2O(ads)(6) H2S(gas) + O  (ads) H2(gas) + SO(gas) +e(7) It is worth  noting that the increase of UV radiation intensity has no effect on sensitivity,  response and recovery times of Te sensors. Also, to evaluate sensor stability, the samples of 100 nm and 200 nm Te film  were  subjected to 8 ppm H2S at room temperature  for 60 days, then  their basic resistance and sensitivity were measured as shown in fig. 14. The results indicate that both resistance and sensitivity of sensors remain  nearly  constant, confirming suitability of Te films for use as sensor. Conclusion In this work, thickness effect of Te films for H2S gas sensing are investigated. A strong dependence  on  electrical resistance and sensitivity to Te film thickness is observed.  This  means that increasing the thickness leads to a decrease of sensor sensitivity and increase of response and recovery times.  Considering  the sensing mechanism of Te thin films which is based on the interaction of ionized oxygen with H2S gas, the grain boundaries and the surface roughness could be considered as active sites for trapping the gas molecules. Thickness increase leads to a decrease of these active sites. The results show that although the Te sensor can operate at room temperature, a decrease of response-recovery times can be obtained at higher operating temperatures. Raman spectroscopy shows that adsorbed oxygen on the surface of Te films can be removed after exposure to H2S gas,  leading to changes in the film resistance,  UV radiation,  as well as response-recovery times. The prepared sensors present a stability in sensitivity and resistance for 60 days after exposure to H2S gas which confirms  their ability to  be  used  as H2S gas sensor.
