The Taklamakan Desert in China

In the Uigur language, Taklamakan may mean you can get into it but can never get out, according to Travel Guide China. We cant verify whether or not the translation is accurate, but the label fits such a large, dry, dangerous place for humans and most animals. Large lakes, including Lop Nor and Kara Koschun, have dried up, so over the millennia, the area of the desert has increased. The Taklamakan Desert is an inhospitable approximately 1000x500 km (193,051 sq. mi.) oval. It is far from any ocean, and so hot, dry, and cold, by turns, with shifting sand dunes covering 85% of the surface, propelled by northerly winds, and sandstorms. Alternate Spellings:  Taklimakan and Teklimakan Lack of Rainfall Wang Yue and Dong Guangrun of the Desert Research Institute in Lanzhou, China, say that in the Taklamakan Desert the average annual rainfall is less than 40 mm (1.57 inches). It is about 10 mm—thats just over a third of an inch—in the center and 100 mm at the bases of the mountains, according to Terrestrial Ecoregions—Taklimakan desert. Bordering Countries While it is in China, and bordered by various mountain ranges (Kunlun, Pamir, and Tian Shan), there are other countries around it: Tibet, Kazakhstan, Kyrgyzstan, Tajikistan, Pakistan, and India. Ancient Inhabitants People would have lived there comfortably 4000 years ago. Mummies were found in the region, perfectly preserved by the arid conditions, are presumed to be Indo-European-speaking Caucasians. Science, in a 2009 article, reports: In the northeastern edge of the desert, archaeologists from 2002 until 2005 excavated an extraordinary cemetery called Xiaohe, which has been radiocarbon-dated to as early as 2000 B.C.E.... A vast oval sand hill covering 25 hectares, the site is a forest of 140 standing poles marking the graves of long-lost society and environment. The poles, wood coffins, and carved wooden statues with pronounced noses come from the poplar forests of a far cooler and wetter climate. Silk Road Trade Routes One of the worlds largest deserts, the Taklamakan, is located in the northwest region of modern China, in Xinjiang Uighur Autonomous Region. There are oases located on two routes around the desert that served as important trading spots on the Silk Road. Along the north, the route went by the Tien Shan Mountains and along the south, the Kunlun Mountains of the Tibetan Plateau. Economist Andrà © Gunder Frank, who traveled along the northern route with UNESCO, says the southern route was most used in ancient times. It joined up with the northern route at Kashgar to head into India/Pakistan, Samarkand, and Bactria.

The Rise Of Chin China - 2076 Words

THE RISE OF CHINA IN INTERNATIONAL RELATION THEORIES INTRODUCTION It is not until today that we see China as a rising power, so powerful that could shake the core of global system. Recent resilient economic growth and other development indexes have been widely quoted in thousands of political writings as the prominent evidence alarming about upcoming â€Å"systemic changes†. In fact, while Europe was still in the shadow of Dark Ages, China was inventing compass, gunpowder, paper and printing technology. While Penicillin was discovered in 1897 by Ernest Duchesne and later Alexander Fleming, China has been using soybean mold as antibiotic measure for already two thousand years. This is explicitly to say that the preeminence Chinese power is not a modern issue emerged from Mao to Xi period, from Long March iconic leaders to modern ambitious technocrats. During colonization period, the West has been constantly disregarding the strength of China and this only changed dramatically after 1976 when Mao death triggered a new period filling with econ omic successes. With very recent understanding of China as an important actor capable of upsetting the status quo of global system, realists are assuming potential war between China and the US, even an all-out nuclear escalation is possible and â€Å"containing† China is the only strategy.

Epilepsy Oral Essay Example For Students

Epilepsy Oral Essay Epilepsy is a neurological condition, which is characterized by repeated convulsions or seizures. There is no known cure to this condition however it is treatable through medical therapy or through surgical treatment. Epilepsy is the earliest recorded brain disorder. People with epilepsy have been feared and isolated by society throughout history. Ancient Greeks thought people with epilepsy had mystical powers. Romans treated people with epilepsy as lepers and outcasts. Other theorists believed that those who had seizures sinned against God and as a punishment were now possessed by demonic spirits. It was early 400 B.C. when Hippocrates linked seizures to problems in the brain. This view was not accepted by his contemporaries and was pushed aside. It was not until the late 1800s that people again began to understand that epilepsy was caused by a brain malfunction. Two European physicians, John Hughlings Jackson and W.R. Gowers, studied people with epilepsy at the National Hospital for Paralyzed and Epileptics in London and proved Hippocrates theory that epilepsy is a brain malfunction. Still, the 19th century health care systems in Europe isolated people with epilepsy and forced them to live in colonies away from society. Until as late as the 1950s, people rarely talked about their epilepsy and therefore hid the disorder from the public. While there are some recognized causes to epilepsy the vast majority of cases have no known cause. In cases where the cause is known it is called Symptomatic Epilepsy. Fewer than thirty-five percent of cases have known causes. The most common o ut of these are h trauma or a high fever at birthh excessively rough handling or shaking of infantsh certain drugs or toxins administered in large dosesh Diseases or conditions that alter or disturb the balance of blood or its chemical structure h or diseases that damage the nerve cells in the brain can also cause epilepsy. However in sixty-five percent of all cases there is no known cause which is called Idiopathic Epilepsy. The brain is a highly complex and sensitive organ as it controls and regulates all our actions. It controls all motor movements, sensations, thoughts and emotions. As well as all involuntary actions such as blinking. The brain works by sending electric charges between different nerve cells in the brain and all other parts of the body as a means of communication. The onset of a seizure is caused by abnormal brain wave activity. The brain waves start off by having an abnormal rhythm caused by excessive and synchronous nerve cell discharges. This change in brain w aves triggers off the seizure. If the abnormal brain wave activity only occurs in one area of the brain it is called a partial seizure whereas if the brain wave activity affects nerve cells throughout the brain it is a generalized seizure. Epilepsy is a common disorder as there is a one percent chance of developing it. Almost fifty per cent of cases appear before the age of ten. In the majority of cases when it id developed under the age of ten the disorder will vanish over a period of time. We will write a custom essay on Epilepsy Oral specifically for you for only $16.38 $13.9/page Order now The diagnosis and evaluation of Epilepsy requires the physician to know all about the seizures when they started, the patients appearance before, during, and after a seizure, and any unusual behavioral occurrences. A background of the familys health history is also commonly used. In addition, an electroencephalogram may help detect areas of increased nerve cell activityThere is no known cure to epilepsy however there is a number of treatments available. There are two main types of treatment available which are drug therapy or surgery. Drug therapy is the most commonly used treatment. The drug treatment is fairly effective with fifty percent of those on a drug treatment will have their seizures eliminated completely. A further thirty percent will have their seizures down to a level where they can still carry on with their normal lives. The remaining twenty percent of patients are either resistant to the medication, or else require such a dose of medication that it becomes preferable to have no control over seizures at all. Surgery is then left as an option to a minority of sufferers. In special cases the injured brain tissue can be removed through surgery which is a procedure similar to a lobotomy. This only happens when medication fails and the injured tissue is confined to one area of the brain and can be safely removed without damaging personality or functions. There are over 40 types of seizure, ranging from seizures which can go totally unnoticed by other people right through to the classic Grand mal seizure A common sort of generalized seizure known as Grand mal. The muscles contract, the body stiffens and then jerks uncontrollably. You may scream as your respiratory muscles contract and your lips may go blue due to lack of oxygen. You then lose consciousness, when you wake up you cannot remember anything and you need time to recover which may range from minutes to hours. .ud1ff2db007c34cfbf4d414fc846625eb , .ud1ff2db007c34cfbf4d414fc846625eb .postImageUrl , .ud1ff2db007c34cfbf4d414fc846625eb .centered-text-area { min-height: 80px; position: relative; } .ud1ff2db007c34cfbf4d414fc846625eb , .ud1ff2db007c34cfbf4d414fc846625eb:hover , .ud1ff2db007c34cfbf4d414fc846625eb:visited , .ud1ff2db007c34cfbf4d414fc846625eb:active { border:0!important; } .ud1ff2db007c34cfbf4d414fc846625eb .clearfix:after { content: ""; display: table; clear: both; } .ud1ff2db007c34cfbf4d414fc846625eb { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud1ff2db007c34cfbf4d414fc846625eb:active , .ud1ff2db007c34cfbf4d414fc846625eb:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud1ff2db007c34cfbf4d414fc846625eb .centered-text-area { width: 100%; position: relative ; } .ud1ff2db007c34cfbf4d414fc846625eb .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud1ff2db007c34cfbf4d414fc846625eb .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud1ff2db007c34cfbf4d414fc846625eb .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud1ff2db007c34cfbf4d414fc846625eb:hover .ctaButton { background-color: #34495E!important; } .ud1ff2db007c34cfbf4d414fc846625eb .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud1ff2db007c34cfbf4d414fc846625eb .ud1ff2db007c34cfbf4d414fc846625eb-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud1ff2db007c34cfbf4d414fc846625eb:after { content: ""; display: block; clear: both; } READ: Confucianism EssayAnother common type of seizure is an absence. This generalized seizure is literally an absence a momentary lapse in awareness. This type of epilepsy is most common in children and teenagers. You stop what you are doing, stare, blink or look vague for a few seconds before carrying on with what you were doing. Onlookers may think you were just daydreaming or may not notice. Before the onset of a seizure some people may experience an aura. An aura is sensation that acts as a warning to an oncoming seizure. The type of aura varies from person to person. They can range from a strange taste to a musical sound that plays in your head. The type of aura can help identify the part of the brain that the unusual brain waves are discharged. It is a common problem that people with epilepsy are discriminated against however this is completely unnecessary as most people can live normal lives with epilepsy. Epilepsy is a common condition that can occur for no obvious reason in anyone. The disease is in no way contagious or transmittable. Most people who develop the condition either grow out of the condition or can lead normal lives through the use of medication or surgery. Therefore those with the disease should in no way be treated any differently to others.

Social Responsibility of a Business-Free-Samples-Myassignmenthelp.com

Question: Disccuss about Does business have a social responsibility?. Answer: Business The term business can be explained as exchange of goods and services for money. It can be further explained as the work related with buying, production and selling of goods and services in exchange of some funds[1]. For a business corporate social responsibility is very beneficial which can be defined as follows: Corporate social responsibility Corporate social responsibility can be explained as the initiative taken by the business organization in which they take responsibility of their effects on environment and society.[2] It can be further defined as the ethical principle according to which the organization should be responsible for their behaviour and effects on society and environment. According to my point of view corporate social responsibility is very necessary for the business organization because this is the era of social business organization. The business organization who actually follows corporate social responsibility (CSR) is the most successful as it gives many benefits to the organization which are as follows: Reputation: CSR practices help the business organization to build good reputation among customers and the society which will further lead them towards the goals of the organization[3]. For example if we talk about India, a company called Indian Oil Corporation limited has highly contributed in the women empowerment which has increased the reputation of the company. Loyalty: CSR practices help the organization to gain the loyalty of the customers. The people generally like to deal with the companies which are literally responsible. The customers expect business to follow CSR practices as they believed that the organization which is socially responsible will provide good quality products. Therefore it ultimately makes them loyal for the organization[4]. Brand image: CSR practices help the organization to build great brand image of the product. When the customers find the organization responsible then they will buy more products and even recommend others also. Increase the ability to attract talent: The organization which follows CSR practices have good reputation and good brand image among people[5]. Every person wants to work in a socially responsible organization. The organization which performs CSR activities will definitely provide the safe workplace to their employees. Therefore it ultimately attracts the talented staff toward them. Competitive advantage: CSR practices help the organization to survive in this dynamic business environment. It gives competitive advantage to the organization as a socially responsible organization has a good image so it attracts large number of customers[6]. They also gain the trust of the customers by being responsible for their effects. Afterwards it becomes even difficult for them to shift to another brand. According to many studies it has been proved that the socially responsible organization grow faster than the other organizations[7]. The socially responsible organization involves satisfied employees and satisfied customers and it also give competitive advantage to the organization. CSR practice is important for the business organization as the CSR practices involves producing quality products, minimum use of chemical, paying fair wages, no biasness, producing environment friendly products and many more. There are many reasons that can describe why a business should follow CSR practices which are: The employees want their organization to be socially responsible because they want to work in a good environment which involves safe workplace, where they can easily share their opinions with others, where they dont have to face any discrimination regarding their identities, where they get fair wages. In this new era of socially responsible organization the employees not only want their organization to be just not bad they want more than this[8]. Every employee of the organization wants recognition and respect in the organization. They want good organization which includes good environment. Customers want business organization to be responsible for their practices. They expect business to follow CSR practices as they believed that the organization which is socially responsible will provide good quality products. A study shows that the average consumer will drive 10 minutes extra to buy the quality products. The customers are even ready to pay extra for those products[9]. CSR practices helps to Attract and retain investors. The investors would only like to invest in the organizations which have good reputation and CSR helps to maintain good reputation among investors. In this new era the investors do not only want to know about the financial aspect of the organization but they also wants to make sure that they are following CSR practices[10]. The socially responsible organization captures the attention of the investors by donating the money to some nonprofit organization. They want investors to know that they not only focus on profits but they are also committed towards the environmental issues and causes. They attract the investors by showing their commitment towards the organization which literally has some impact on the lives of the people. CSR practices helps in increasing media coverage. No one will know about your good work till it gets acknowledged by everyone so media coverage is very necessary. Corporate social responsibility is when an organization is doing something good for the environment and society and beyond that. Therefore when the organization is doing good work then it must be covered by media which will create the good image of the organization. CSR helps in reducing cost. According to my point of view CSR helps in reducing cost for the organization as it helps the organization to retain customers, suppliers, investors and employees. They do not need to do advertising to attract the customers and investors[11]. Under CSR practices, the organization by reducing the use of resources can help the environment and save funds also. With some simple efforts an organization can lower the range of cost and increase the range of profits. CSR practices helps in encouraging growth of the organization. The CSR practice gives competitive advantage to the organization as well as strength to the organization to survive in this dynamic environment. Ultimately it leads the organization towards the growth. Under CSR practices employers and employees both get to learn so many new things which can be applied in the workplace[12]. By indulging in CSR practices organization get to learn entirely new things which will encourage the overall growth of the organization. CSR practices helps in engaging customers. No one will know about your good work till it gets acknowledged by everyone[13]. Few years ago a company called Wallmart has established itself as the principal of environmental efforts. Wallmart has become the principal of environmentalism then in 2008, it conducts an ad campaign to create awareness among people regarding environmental issues. Therefore by using CSR one can engage with customers easily. If the message is positive and good then it will be easier to start a conversation with customers. CSR also helps to engage employees. As it helps to engage customers likewise it also helps to engage employees. The organization is losing an opportunity if the employees are not aware of the CSR practices of the organization[14]. A company called Solo Cup Company organized a Sustainability Action Network to make the employees proactive in regards with community service. Conclusion It can be concluded that corporate social responsibility is very beneficial and important for the business organization as it provides competitive advantage to them. It also helps to engage with employees and customers. It also helps to reduce the overall cost of the organization. It enhances the overall skills of the organizations as it helps to increase both the professional growth and personal growth Bibliography Branco, M.C. and Rodrigues, L.L., Corporate social responsibility and resource-based perspectives, Journal of business Ethics, 69(2), pp.111-132 , 2006.

An Unforgettable Camping Experience Essay Example

An Unforgettable Camping Experience Essay I couldn’t believe the day had finally come. My friends and I had been talking about it for what seemed like months. Every year our class 5B takes a trip to the Sahara Campgrounds. As soon as you see the entrance sign, a sudden tingling feeling bubbles through your body knowing a few days of relaxing from school work is about to start. On a sunny day in July of 2009, our class got into the bus and headed to our campground. I sat comfortably in between my best friends Rona and Tamara, while Nadia and Karin sat at the very back of the bus and behind them sat my younger cousins Sarah and Salam. It was a little tight and looked like everyone was sitting on top of each other. After what seemed like forever, we got out and were greeted by the camp consular for instructions on how to setup our tents and how to protect ourselves from wild animals such as bears. Once we finished putting up our tents, some of the girls started playing hide and seek while the others sat around the camp fire sharing stories and laughing.

We would cook hot dogs hamburgers, fish, corn on a cob, and everyone favorite smores. The students all took turns telling a scary story. Rona and Karin where screaming so loud it could have been heard from miles away. But, Nadia, Tamara and I, just sat quietly waiting for the next story as we knew most of the kids where making them up. Evening came and everyone was getting ready for bed. Just few minutes after we turned off the lanterns, we heard loud shouting and screaming coming from outside our tent. I peeked out of and saw a large black bear. All the students sat quietly in their tents watching the bear open the garbage dumpster and dump it out. Then, the large bear turned to our food containers and tried to open by lifting them over his head then throwing them on the ground causing them to release. Once the bear got all he needed he left without hurting anyone, but destroying most of our food for the week. At the end of the week we waved good-bye to the campgrounds. Keeping the memories of the dazzling lake, great stories by the fire, the sweet smells of campfire food and most important the unwelcomed visitor the large black bear. I realized that knowing how to protect ourselves in the case of a wild animal attack is valuable knowledge that will never be forgetting. Having a ripping feeling of sadness, Id leave with a smile on my face, knowing Id be back next year.

In mid March 1824, his company rediscovered the South Pass it was a passage to the Northwest through Wyoming and descended into the Green River area for the spring hunt. In July 1825, Jedediah attended the first Mountain Man rendezvous at Henry's Fork then accompanied William Ashley to St. Louis with the season's bounty of furs. In route downriver, Ashley took Jedediah as partner to replace the retiring Andrew Henry. In August, he led seventeen men to appraise the trapping potential of the region south and west of the Great Salt Lake. When he and his band arrived at San Gabriel Mission near Los Angeles, they became the first Americans to cross overland to California, entering from the east. They were blocked by the Mexican govenor of California, Jedediah had to change is plans to explore Oregon and so he journeyed to the American River near Sacramento instead. His band reached the Utah Nevada border near Grandy, Utah, continued on the Skully Valley and reached the South tip of the Great Salt Lake two day ...

How Soccer Explains the World Essay Example | Topics and Well Written Essays - 1000 words

How Soccer Explains the World - Essay Example Franklin Foer, whilst penning this book has taken a close look at the role that soccer has played in the global cultivation of competition, mad rivalry that has sparked off a number of controversies, varied sagas and what not. He has discussed issues like world trade as well as the linkage of the Western culture where soccer celebrities like Zidane, Ronaldo and Beckham are perceived to be the biggest that there were and still are in the world. They have no less a value when we compare them to American President Bush or even the beheaded Iraqi dictator, Saddam Hussein. There are the sport mad societies that he has openly discussed as well as the role of this game in religions like that of Islam, the phenomenon like hooliganism and so on and so forth. The justification that Foer has provided raises quite a few eye brows since there is enough food for thought as concerns to the game itself and the working methodologies which go hand in hand with the Western way of doing things, one such igniting a level of competition that is bound to be remarked as unmatchable right from the onset. Franklin Foer has remained passionate throughout his book, so much so that his passion knows no boundaries whilst raising an energy which looks all the more contagious than anything else. The religious sentiments that he has brought forward are however a step further than the passion that he has discussed in his book courtesy the game itself. Foer has made sure that his book brings to life with the portraits and profiles of different players like the ones hailing from Nigeria and then there are the issues which restrict sports participation on the part of the Iranian women as well. There are the parallel worlds of Brazilian soccer as well as politics which Pele went into and hence game became so much more politicized as a result of this. What Foer wants to highlight is the fact that the aspect of globalization has

Internet - Essay Example As said by Berners-Lee, World Wide Web should be accepted widely by the world, leaving a community behind is not justified. The focus here is on the community, which face problems in accessing the web because of some form of disability. Disabilities may be many for e.g. blindness, poor sight (partial blindness), colour blindness, deaf users, epileptic users, users unfamiliar to technology, non-English users, learning disabled people, aged people (senior citizens) etc. As per U.S. Census Bureau it is estimated that around 50 million people in United States have some form of physical or mental disability. To make the Internet really universal and explore its power of universality there has been a lot development in the field of making Internet more accessible by disabled people. The paper elaborates such developments in the field. Web 2.0 has led to the development and growth of web-based communities like social networking sites. There has also been considerable amount of development for making these sites accessible and easy for disabled people. Blind users who do not have the sight may utilize the screen reader. The screen reader reads the content of the page and reads aloud the selective part of page, which is important for information and page navigation (Webcredible, 2008). For users with partial or poor sight, the facility to enlarge the text is there. The text of the web site can be varied in the size but the text embedded in the images cannot be resized and so an alternative to images is kept which can render plain text against the images. The figures show that 1 in 12 men and 1 in 200 woman have some form of colour blindness (Webcredible, 2008). As a solution to this, the sites are trying to provide more flexibility in changing the text colour, size and type. A point under consideration is majority of the sites uses CAPTCHA images to register new users. This creates an inequality for

Argues what Matthew Dickman's prescription for the good life is Essay

Argues what Matthew Dickman's prescription for the good life is. (please make a better topic) - Essay Example The poet’s style and expression match the daily lives of American people, so he appears a poet of the people who writes for the people and they can related with his experiences as his experiences are similar or somewhat grounded in American culture. This paper scrutinizes three of the above-mentioned poems in terms of poet’s prescription of good life. He elaborates about his reading experiences and his comprehension related to those readings. His toilet as a whole was constructed by a company named as American Standard and he relates his experiences of using the toilet with the formation of American standard. He wants people to enjoy themselves and involve in partying for their happiness and merriment, as being a part of American society, people are allowed to enjoy as they like. There are also some ill happenings in life, but as per the poet’s perspective, a person should ignore his losses and try to be happy by clubbing, doing sex and going to parties. He elaborates about his activities in the toilet and connects them to his happiness. He also wants to be as comfortable while being in toilet and is not ready to hurry up. At the end of the poem, when he recalls about his visit of Africa, he seems to mention the African Americans in America whom he regards to be kind and friendly people. His poem informs about the activiti es what American people usually do. He poem, American Standard not only appears as a narrative of his experience and his life, but also about the accommodation that America gives to foreigners such as African Americans who have migrated from Africa to settle in America. He says, Everything that goes into the American Standard becomes a part of it or melts into it such as African Americans have become a part of America and its pop culture. The poet mentions in the poem about partying and get together of people along with his sex with a women who is engaged to a man from

Wireless Networking And Malicious Association Computer Science Essay

Wireless Networking And Malicious Association Computer Science Essay Wireless security is to prevent unauthorized user to access the wireless network or damage the computer by using wireless network. When the wireless technology has been first introduced to the world, it already has few danger methods that will harm the users desktop or laptop, but that time cracker and hacker dont have any resources to crack or hack a network by using wireless technology. At that time, the wireless network only use by the big company. But now day, wireless network is very common, every corner of the world like cafà ©, shopping mall, school, or college that has provide wireless access for the people to access it. Not only cafà © and college using wireless network, at other country it use wireless technology to connect whole citys network. With this technology, people that around the wireless router can easily to access the wireless network to do the search of the information, check mail or play online game. Because of the wireless technology, now day, every laptop has wireless adapter card pre-install inside and make the laptop more portable and let them can connect to internet easily. Not only for laptop, wireless technology also make benefit for the desktop. Desktop can connect to network by installing a wireless adapter card or plug in an USB wireless adapter then desktop can connect to a network and without cable messy around the floor. In this case, wireless technology has become widely use and because of this reason, the risk of using wireless technology has increase and let many hacker found the way to hack the wireless network. All of security risk is related to the current wireless protocol and encryption method. Most of the wireless networks use IEEE 802.11b for standard communication and IEEE 802.11b have already became standard wireless networking technology among the small business user and home user. The IEEE 802.11b can support the indoor distance from several meter to several hundred meters, and can support the outdoor from several kilometer to several ten of kilometers by using unlicensed wireless band. Now day, the wireless network devices normally are equipped with Wired Equivalent Privacy (WEP) data encryption. WEP data encryption was based on 64-bit RC4 encryption algorithm. Other that 64-bit RC4 encryption algorithm, 128-bit encryption algorithm is another data encryption on the WEP data encryption. But this kind of device is more expensive compare with 64-bit RC4 encryption and beside that, all the nodes must use the same encryption level. 1.2 Aim of Research Aim of the research is to implement the wireless security into the CSC System to prevent unauthorized user to access the wireless network. To increase the security level of the wireless network. To avoid the data or information inside the server or computer been hacked by unauthorized user. To increase the safety of the data transfer between server and computer. To add extra encryption method to encrypt the packet need to be transfer. To prevent unauthorized user to shut down whole system though the wireless access point. Chapter 2: Main Body 2.1 Wireless Security Concept A research has been carried out about the concept of the Wireless Security and how to enhance the wireless security. Wireless Security is to prevent an unauthorized user to invade the server database and bring harm to entire network. Below are the results of the research. 2.1.1 Unauthorized Access According to the research, have a lot of way to break into the wireless access point without an authorization. The unauthorized access will cause companys daily operation failure and lose profit. Below are the some of the examples unauthorized accesses. 2.1.1.1 MAC Spoofing MAC spoofing is a technique to change an assigned MAC (Media Access Control) address to another different MAC address. When a person using this technique, he/she has his/her reason to changes a network devices MAC address, whether is legitimate or illegitimate. Changes a network devices assigned MAC address allows bypass the access control list on the server or router, either hiding a computer on a network or attacking a network by simulate another network device. MAC spoofing occurs when a cracker or hacker has the ability to listen the network traffic that passed by and through it; the cracker or hacker can identify the MAC address of the computer with network privileges. Most of the wireless system allows MAC filtering to only allow authorized computer that with specific MAC address to access the network. The computer that dont has specific MAC address cant access the network, so the cracker or hacker use a program which has network sniffing capability and combine with other software or program to pretend the computer has any MAC address that the cracker desires. (Wikipedia, 2010) 2.1.1.2 Malicious Association The Malicious Association is hacker that can connect to company network by using their cracked laptop. This type of laptop is known as soft AP (Access Point) and this type of laptop is created by using some software that makes the hacker laptops wireless adapter card look like a legitimate access point. After the hacker has already gained the access to the company network, the hacker can steal the password or plant the computer virus into the network. (Wikipedia, 2010) 2.1.1.3 Ad-hoc Network Ad-hoc network, also known as peer-to-peer network built up between two or more wireless computers and these wireless computers dont have access point in between them. Ad-hoc network usually provide little protection, encryption method to the network. When a company or person using Ad-hoc network and wired infrastructure network together at the same time, and will link up a secured network to an unsecured network. Connect two different network topology need to have a bridge between them. Bridging is in two forms. User can connect the network topology y a direct bridge and indirect bridge. Direct bridge need to configure by the user and indirect bridge is user share resource on the user computer. The indirect bridge is provides two security problems. The first problem is the data can be obtained through the secured network on the user computer and this data exposed to other user discovery via the Ad-hoc network bypassing the user secured network. The second problem is a Trojan, computer virus or worm can be placed on the user computer through the Ad-hoc network. The unauthorized user no needs to crack the password of the network and can place the computer virus through the Ad-hoc network. (Wikipedia, 2010) 2.1.1.4 Denial of Service C:UsersZoukyDesktop424px-Stachledraht_DDos_Attack.jpg DoS (Denial of Service) or DDoS (Distributed Denial of Service) will occurs is when an attacker continues non-stop bombards an attacker targeted access point with bogus request, failure messages, or other commands. Denial of service will cause other users cant get into the network and also will cause a network crash. The DoS attack will expose a little bit of the data to the attacker, when the DoS attack happen, the interrupted network will prevents the data flow and also indirectly prevent the data from being transmitted. After the DoS attack has been performed, the attacker will start to observe recovery of the wireless network. During the initial handshake code is start to re-transmitted to the wireless network, the attacker continue what he remain. The attacker will record down the initial handshake code and use cracking tools to analyze the security weakness and exploit this code to get an unauthorized access to the system. (Wikipedia, 2010) 2.1.1.5 Man-in-the-middle Attack Man-in-the-middle attacker using a computer to sets up a soft AP (Access Point) and enticing other computers to log into the computer that already been sets up to soft AP. After this all are done, the attacker connects to a real access point by using other wireless card and the attacker will offers a steady flow of the network traffic through the done hacking computer to real network. Man-in-the-middle attack forces other computers AP drop the connection to real network and reconnect to attackers soft AP. This allows hacker to receive what other computers want data need to send out to real network. (Wikipedia, 2010) 2.2 Basic Security for Wireless Wireless network exist in this world already has a decade, at that time the security for the wireless network still not strong enough to prevent infiltrate by hacker or cracker. But at that time the hacker doesnt familiar on technology or technique to hack the wireless network. One of the reasons is the hacking device to hack the wireless network still hard to achieve on that time market. After a decade, the technology and technique to hack a wireless network and the step to build up the hacking device can found on internet. So now day the wireless network users need to have a strong and better wireless security to secure the wireless network. Below are the basic securities for wireless network for the first wireless network has been introduced. 2.2.1 Service Set Identifier SSID (Service Set Identifier) is a common network name for a device in a wireless LAN and some of the wireless device has its own default SSID. The default SSID can be replaced by other string and normally this string is generated randomly. SSID is to identify a name for particular wireless access point. All wireless network need to have SSID within the wireless access point just can communicate each other. The client doesnt know the SSID of the access point, then that client cant simply access the network; this is to prevent hacker to invade network by access through access point. The hacker need to know the SSID of a network just can complete the 802.11b protocol to access the network. The access point will broadcasts the SSID by the beacon inside the wireless device. However, even the broadcasting of the access point is turn off, the SSID still can detected by hacker with undetected monitoring of particular network or sniffing. So, all the clients need to know the SSID of the acce ss point before can make connection to the wireless device. (Bhagyavati, Wayne C. Summers and Anthony DeJoie, 2004), (Prasad, 2007) 2.2.2 Medium Access Control Address Filter Each wireless access point can be configured only accept the clients MAC address that already registered inside the wireless access point. With this function, the network administrators can limit the access of the client into wireless network by register the clients MAC address into the wireless access point. Most of wireless devices MAC address is unique and MAC address filter only allow the clients MAC address already registered in the wireless access point to access the network. The entire clients MAC address will store into MAC address ACL (Access Control List) and wireless access point will denied other wireless device if the wireless devices MAC address is not register inside wireless access points MAC address ACL. (Bhagyavati, Wayne C. Summers and Anthony DeJoie, 2004), (Prasad, 2007) 2.2.3 Wired Equivalent Privacy WEP (Wired Equivalent Privacy) is intend to give wireless users have a security scheme is equivalent to the wired network security. WEP doesnt provide any superior level or higher than that level of security, although WEP doesnt has superior level of security but it security level is equivalent with wired network. In the practice, the result show that the security level of WEP need to equivalent to wired network security is hardly to achieve. The use of WEP is to prevent the wireless client from sending and receiving data from the wireless access point, the wireless clients need to have the correct WEP key just can connect to the wireless access point. Now mostly of the network devices is equipped with the WEP data encryption and the encryption algorithm for the WEP is 64-bit RC4. Some of the network device capable to uses 128-bit encryption algorithm. After WEP is active, each 802.11 packet will encrypted by 64-bit RC4 key with RC4 cipher stream. This key is composed of 24-bit IV (I nitialization Vector) and other 40-bit is WEP key. IV is chosen by the sender and the IV can be change, this make every packet wont encrypt with the same key. Another additional 4-byte is for ICV (Integrity Check Value); ICV is computed and appended on the original packet. RC4 cipher stream is generated by 64-bit RC4 encryption algorithm. The WEP encryption algorithms work on a key that share between wireless device and wireless access point. The packet is encrypted by using the key before packet is send out and all packets wont have same cipher stream. The packet receiver use integrity check to ensure that the packet is not modified during the transmission. Most of the systems are share a single key among all the wireless device and wireless access point. The Integrity Check Field is to ensure the packets are not been modified during the transmission and Integrity Check Field also encrypted with the RC4 cipher stream. WEP is using CRC-32 (Cyclic Redundancy Code 32) mechanism for i ntegrity check. CRC is defined as a class of checksum to prevent overflow by dividing the message into binary. (Bhagyavati, Wayne C. Summers and Anthony DeJoie, 2004), (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005), (Prasad, 2007) 2.3 Comparison between SSID, MAC Address Control Filter and WEP From the research, SSID (Service Set Identifier), MAC (Medium Access Control) address control filter and WEP (Wired Equivalent Privacy) are the basic security for the wireless network. This three security methods can implement together in one network. Because these are basic security for wireless network, so the security methods are easy to break by unauthorized user. If not implement other security methods and only just implement SSID, MAC address control Filter and WEP into wireless network, that wireless network will not secure under protection of these three security methods. The wireless access point will broadcast the SSID to the wireless client and wireless client just can access to the access point. When the access point broadcast its own SSID, the entire nearby wireless client will know the SSID of that network or access point, even the unauthorized users also will know the SSID of the network. The unauthorized users will attempt to access the wireless access point. And the wireless access point can close the SSID broadcast function; mean that the SSID is hidden. But when the authorized user requires connecting to the access point, the authorized user will broadcast the SSID to the wireless access point, if the SSID broadcast by the authorized user is match with the SSID of the access point. The authorized user just can make connect to the access point. This make hacker a chance to hack the access point because when authorized user is broadcasts the SSID to the access point, hacker can capture the packet that broadcast by the authorized user and make connection to the wireless access point. The wireless devices MAC address will store inside the wireless access point ACL (Access Control List), the wireless devices MAC address need to be match with MAC address inside the wireless access point ACL just can connect with wireless network. If that wireless network has more than 20 computers need to connect to the wireless network, then the network administrator need to enter all the computers MAC address into the wireless access point ACL. This will make the network administrator very troublesome enter the MAC address one by one and MAC address can be forged. WEP has been considered as a failure in wireless security, at the end it still accepted by the IEEE because WEP wasnt aim for provides fully security for wireless. WEP encryption is very easy to crack by the unauthorized user. WEP only authenticates the wireless client. This allows an unauthorized user to capture the packet send by the wireless client. WEP key is easily lost or stolen by unauthorized user and if the stolen WEP key hasnt been report to the network administrator, the network administrator wont able to detect the unauthorized user has already infiltrated the wireless network. If the stolen WEP key has been reported, network administrator require to change the entire devices that have use the same WEP key with stolen devices WEP key. If the company or enterprise has more than thousands of wireless user using that wireless network, this can be a very difficult task for the network administrator to change the entire WEP key for each wireless users. Like just mentioned, the WEP authentication message is easy to forging by the unauthorized user. Unauthorized user can capture the authentication message that send by the wireless client and forge a new authentication message; unauthorized user can use this forged message to associate with wireless access point. The management for WEP key in not specific in WEP standard. Since dont have management for WEP key, then WEP key will be use for a long term and lack of quality. Most of the wireless network uses one WEP key and share between the entire network and the entire wireless clients access point need to program with same WEP key. Because of this reason, network administrators rarely change the WEP key. SSID, MAC address control filter and WEP is basic security for wireless network; these methods still cant apply in wireless network. Just using SSID, MAC address control filter and WEP are not enough to prevent the security break. These methods require associate with other security methods to enhance the wireless security to prevent security break. 2.4 Advanced Security for Wireless From the research that carried out, advanced wireless securities are to replace the basic wireless security and improve what basic wireless security vulnerability. 2.4.1 Wi-Fi Protected Access WPA (Wi-Fi Protected Access) is a certification program that created by Wi-Fi (Wireless Fidelity) Alliance; WPA is a subset of the IEEE 802.11i. This technology is designed to response to the weaknesses that found in WEP. WPA will generate the key based on the master key and the master key never use by WPA. To encrypt the data, WPA is much more secure than WEP. Key management and updating in WEP is poorly provided, the secure key management is a built-in function in WPA. Mean that WPA can update and manage the key easily, not like WEP. If WEP need to manage or update the key, the network administrator needs to change entire wireless client key that has connection with the wireless network. WPA got one key only and that is master key like just mentioned, network administrator only require to change that master key then WPA will generate the key based on the master key. Generated key is hierarchy of the master key. So this make the management and updating become much easier. The IV (Initialization Vector) values can be reuse and the length of the IV is become longer, from 24-bit increase to 48-bit. Another additional part, the IVs are the sequence counters for the TSC (TKIP Sequence Counter), to protect the loop of the data. The WEP message integrity protocol CRC-32 has been proved ineffective. Because of this reason, WPA uses a MIC (Message Integrity Check) mechanism to replace the WEP message integrity protocol. The correct MIC is very difficult to guess. (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005), (Bhagyavati, Wayne C. Summers and Anthony DeJoie, 2004), (DifferenceBetween, 2010) WPA has 3 improvements over WEP: Improved Data Encryption WPA improves the data encryption through the TKIP (Temporal Key Integrity Protocol). TKIP generates the key by using hashing algorithm and adding the integrity checking feature, this will ensure the key havent been edited by other person. TKIP is a Temporal Key hash Function and it is another option to WEP to fix all security problems that WEP has and it doesnt require installing other new hardware. TKIP same like WEP, use RC4 stream cipher to encrypt and decrypt data and all involved clients require share the same key. This key must be 128-bit and it calls Temporal Key (TK). The Initialization Vector also include in TKIP. Even if the TK is shared among all the wireless clients, all wireless clients generate different RC4 key stream. Since the communication participants perform a 2-phase generation of a unique Per-Packet Key (PPK), which is used as the key for the RC4 key stream. (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005) User Authentication User authentication in WPA is through the EAP (Extensible Authentication Protocol). This function is missing in WEP and WEP access to the wireless network is based on computers network cards MAC address and MAC address is very simple to be stolen. The purpose of EAP is to create a more secure public-key encryption system to ensure that only authorized user can access the wireless network. (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005) Integrity WPA has a new mechanism call (MIC) Message Integrity Code for TKIP is computed by a new algorithm, name Michael. MIC is computed to detect errors in the data contents, either is transfer errors or purposely change the data content. The Michael is a 64-bit MIC and need to add to the data and ICV (Integrity Check Value). (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005) 2.4.2 Robust Security Network RSN (Robust Security Network), also call as WPA (Wi-Fi Protected Access) 2. At year 2004, concept of RSN has been released, where the wireless devices need to support by additional capabilities. RSN is fully tested by Wi-Fi Alliances. RSN has a whole new standard and architecture to utilize the IEEE 802.1X standard for AES (Advanced Encryption Standard) and access control. RSN is using a pair-wise key exchange (Four Way Handshake) protocol, RSN also utilizing with 802.1X for key management process and mutual authentication. Now, 802.11i allows for the network implementation and also can use TKIP (Temporal Key Integrity Protocol). By default RSN uses CCMP (Counter Mode MAC Protocol) and AES (Advanced Encryption Standard) to provide for a scalable and stronger solution. AES is a replacement for RC4. Data transmission between the wireless access point and wireless device, RSN uses encryption algorithms and dynamic negotiation of authentication on the data transmission. The authentication of RSN is based on 802.1X and EAP (Extensible Authentication Protocol). Encryption algorithms and dynamic negotiation of authentication make RSNs security more secure and save. RSN is stronger and better than WEP and WPA because RSN is using dynamic negotiation, 802.1X, EAP and AES. Unfortunately only the latest devices have the capability let RSN to accelerate the speed of algorithms calculation in wireless client and wireless access point; now day of wireless product cant fully provide the performance of RSN. (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005), (Bhagyavati, Wayne C. Summers and Anthony DeJoie, 2004), (DifferenceBetween, 2010) 2.5 Comparison between WPA and WEP WPA (Wi-Fi Protected Access) is the solution for the WEP vulnerability, has some critics done for the WEP, the WPA has numerous enhancements over WEP. WPAs TKIP encryption algorithm has fully enhances the WEPs RC4 encryption algorithm. TKIP make the data encryption more efficient and replace the RC4 vulnerability. WPA has made the key management became much more easier compare with WEP, because the WEPs key require enter one by one to the wireless client, if the company has more than thousands users then the network administrator need to enter more than thousands keys into the users computer. If the key is hacked by unauthorized user, then network administrator need to change key for entire companys computers. On the other hand, WPA no needs so troublesome, WPA only needs to enter one master key, and then WPA will generate key according with the hierarchy of master key, after that WPA will assign the key to the clients and the key is generated in 48-bit of IV size. Even the company g ot more ten thousands users also no need to trouble the network administrator. If one of the key has been hacked by unauthorized user, TKIP just need to generate a new key then network administrator can info the wireless client to change the key. WPA has EAP to authenticate the wireless user. WEP is using MAC address to authenticate the wireless user and some of the wireless devices MAC address can be forged. If the wireless devices MAC address has been forged by unauthorized user then the unauthorized user can easier to connect the wireless network without known by the network administrator. Network administrator also wont notify the wireless network is infiltrated by the unauthorized user until the wireless user report there is a missing MAC address. WPA is using EAP to authenticate the wireless user and the EAP for each wireless client is hard to forge by unauthorized user. If the EAP of the client is forging, but the unauthorized user still need wireless clients private key just can access the wireless network. WEP dont have error checking for the data content, and this will cause the looping of the data. If cant prevent replay attacks and will cause the wireless network crash. WPA has inserted the MIC into TKIP and IV sequence mechanism; this is to prevent replay attacks in the wireless network. MIC and IV sequence mechanism support for the existing wireless infrastructures not require installing new wireless device. Adding MIC and IV sequence mechanism without install new wireless device, adding these two methods can increase the wireless security and also without increase the installation cost of wireless device. Compare WPA with the WEP, WPA has solved a lot of WEP vulnerabilities. This make WPA is more secure compare with WEP because WEP only is basic security for the wireless network; it doesnt provide any protection for the wireless network. WEPs security methods can let a small enterprise to setup a small wireless network. For the big company, WEPs security methods are hard preventing the unauthorized access from outsider. 2.6 Comparison between WPA and RSN For now, never the less, RSN (Robust Security Network) is the strongest wireless security protocol for the wireless network. RSN provide stronger data encryption algorithm and all advantages of WPA. The RSN data encryption algorithm method is using AES (Advanced Encryption Standard) to encrypt the data. What advantages WPA have all included in RSN, expect the RSN data encryption algorithm is more advance. For WPA require upgrade for the software and firmware of the wireless device for the existing wireless network infrastructure, but the RSN doesnt support existing wireless network infrastructure, require upgrading the wireless device in order to implement AES. Implement RSN into the existing wireless network infrastructure require extra cost for just upgrade the hardware. RSN need large amount of processing resources in order to protect the wireless network. Mean that implement RSN will reduce the wireless network performance by processing the data transfer or verify the wireless client. 2.7 Table of Comparison between WEP, WPA and RSN Below is summary of the comparison between WEP, WPA and RSN: Features of Mechanism WEP WPA RSN Encryption Cipher Mechanism RC4 RC4 / TKIP AES / CCMP CCMP / TKIP Encryption Key Size 40 bits 128 bits 128 bits Encryption Key Management None 802.1x 802.1x Encryption Key Per Packet Concatenated Mixed No need Encryption Key Change None For Each Packet No need IV Size 24 bits 48 bits 48 bits Authentication Weak 802.1x EAP 802.1x EAP Data Integrity CRC 32 ICV MIC (Michael) CCM Header Integrity None MIC (Michael) CCM Replay Attack Prevention None IV Sequence IV Sequence (Halil Ibrahim BulBul, Ihsan Batmaz and Mesut Ozel, 2005) Chapter 3: Conclusion 3.1 Achievement of Objectives 3.1.1 To increase the security level of the wireless network. In chapter 2.2 until 2.4, the different wireless securities provide different service. 3.1.2 To avoid the data or information inside the server or computer been hacked by unauthorized user.

In chapter 2.2 until 2.4, the methods to prevent the unauthorized user to connect with wireless access point. 3.2 Research Conclusion A research has been carried out to finish this seminar report by studying the type of the unauthorized access, concept of the wireless security and how efficiency is the wireless network security by determine the wireless security method. Now wireless has already became widely use by company or enterprise, even at home also can using wireless to connect to internet for home purpose like surfing the internet. The reason why so many people like to use wireless network compare with wired network, is because the structure of wireless network is more neat and easy to manage. At the time wireless just came out to the market, the security for the wireless still breakable by hacker or cracker but need a lot of resources to break the security of wireless network. Because last time, wireless network just introduced, the hacker or cracker lack of technology and technique to break the wireless network. Still after few years, the technology and technique to break the wireless security can found in internet.

Essay About Family: Families Torn Apart :: essay about my family

Family ties have been a sour topic in my life since as long as I can remember. Through the years I have managed to cope with the reality of being on my own. Though it was not easy, I have been through more than most people my age. One of the hardest things I had to cope with was moving around as much as we did. I was born in Nurnberg, Germany while my father was in the military. When I was two, my parents divorced and I stayed with my father and lost all contact with my mother until I was 18. After they divorced, dad and I moved in and out of three states, and ended up in Wausau. Growing up with an abusive father, and without my mother, was very difficult to manage. To make matters worse, I attended 12 schools before high school, I had no friends. Homework was always a struggle for me, given that I attended 12 different schools. It seemed as if I was always behind or ahead of the class, because the last school was at a different pace or taught things differently. I have grown up without relying on family but relied on myself. Even today I have little or no contact with my family. My mother and all her relatives live in Oregon. I had the pleasure of reuniting with my mother in 1994. When we met again after 16 years I decided to live in Oregon with her. I stayed in Oregon for almost two years by then it was apparent that my mother and I lost the bond that a mother and child should always have. We were separated for so long, and I was at such a young age that I found it difficult to be close to her. I have since moved back to Wausau, and started a family of my own. On occasion I talk to my mother on the phone but this has never been a very fulfilling relationship either. Although unfulfilling, it has allowed for some progress in our relationship. In the same way I have lost connection with family so has Chakkravann "Chucky" Saukom. During an interview with my friend Chuck, I learned some very interesting things. Chuck moved to the United States in 1975 with a "first class ticket from the U.

Oracle Bone Essay

Religion in Shang Dynasty Religious practice has always been an essential part of Chinese Culture. Even in the period of the Three Augusts and Five Kings, religious practices occurred. However, it is not until the Shang Dynasty when actually records of spiritual communication were founded. Oracle Bones were recorded of communication between human and spirits. The ritual of cracking oracle bones told what ancient Chinese concerned the most – the relationship between spirits and nature. The intricate Oracle Bones not only reveal the religious aspect of the Shang Dynasty, but also relate the cultural and olitical system in ancient China. During the Shang Dynasty, Kings were granted the power to communicate with spirits. Mostly importantly, spirits informed kings about the unknowns. When Shang kings have questions regarding the future and their relationship with spirits, they assigned priests and shamans to become medium between human and spirits. When shamans were asked to foretell for the king, they drill hollows in shells and apply red- hot poker to these shells. They believed this ritual would attract spirits who were nearby to answer kings’ questions asked by shamans. Shamans’ main task was to nterpret spirits’ respond through the different cracks on shells. These kinds of predictions were said to be legitimate the kings were the ultimate representative of the spirit. Most of the time, kings requested to perform oracle bones divination to learn from spirits regarding the success of harvest, outcomes of battles, and schedule of sacrifices to spirits. For example, the King asked: â€Å"Will Di order rain sufficient for harvest? † (Eno 46). During earlier years of Shang Dynasty, the outcomes of harvests were more important to the people. Nevertheless, by the end of the Shang Dynasty, a large portion of divinations were performed to know the schedule and proper scarifications to spirits and ancestors. There were scarifications everyday for different ancestors and spirits according the results of divinations accumulated overtime. After oracle bone divinations were performed, kings would perform sacrifice to the assigned spirit at a specify time with appropriate goods. When an oracle divination indicated a negative answer from spirits, for instance defeat in battles, kings would then sacrifice to spirits hoping for spirits’ help to change the result. Shamans would slaughter animals and/or humans according to spirits’ preference. The result of appeasing spirits could lead spirits to provide extra helps for the people. On the other hand, if the king sacrifice the perfect quality and quantity of goods to a specify spirit but the king did not get his preference; kings could temporarily stop sacrificing to this spirit until the effect of previous scarifications were shown. Therefore, human scarification and spirits’ effectiveness created an economy between human and heaven. This economy applied more on the loyal level than the family level. During Shang Dynasty, family could only sacrifice to their own linage of ancestry. It was a crime to sacrifice to other linage of ancestries because only the king had this power. Family often sacrificed to hope ancestors would bless the family to have male children which can extend the family-tree. Thus, only the royal family had the Shang king can communicate and sacrifice to all linage of ancestries, which include Shen (natural deities), royal ancestors, and cultural heros. People in Shang Dynasty worship the greatest spirit – Di (Tian). Yet Di do not receive any sacrifice ompare to other spirits. Tian, which is said to be equivalent to Di, was so powerful that other spirits could never match their power with D’. Di was a significant factor of Shang people’s religious believe that was indicated in the oracle bones but Tian was not indicted in any evidences at all. On the other hand, Shang people viewed Shen as the power of nature, including power of earth, river, mountains, rain, thunder, and the power of directions, etc. in the early stage of Shang Dynasty, oracle bones divinations were directly performed to communicate with Shen to foretell harvest esults. Shen, unlike Di, did take sacrifice in order approve kings’ requests. For example, king asked, â€Å"Shall we call upon Que to sacrifice a hound by fire to Cloud? † (Eno 48). Thus, Shen was the second highly respected power after D’. Shang kings also sacrifice to spirits of their royal ancestors, including parents, grandparents, forebears of ruling king, relatives. These spirits were located inside the royal familys palace, and their tablets were put together with other ancestors of the same family. Kings worshiped his linage of ancestors to hope they would bring fortune to the royal amily and the countries. When the current king died, he became part of his linage. Oracle bones divinations were use to communicate with royal ancestor spirits: â€Å"Should we protect the kings eyes against Grandmother Ji? † (Eno 49). Current kings Other families only sacrifice to their own linage as well. This ancestor worship ritual was established during the Shang Dynasty and is still performing in modern Chinese culture. Finally, kings also sacrificed to ancient cultural heroes, yet they were the less prominent group of spirits. Thus, religion practices in Shang Dynasty were an essential part of Chinese ultural before and in todays society. The use of oracle bones to predict future allowed reader to date the first actual evidence of Chinese religion. The written records left by Shang Dynasty created a clear picture of the cultural and politic aspects of ancient China as well. The relationship between human and spirits remains to be a significant part of Chinese people’s religious belief. I grew up practicing ancestor worship.

Analysis of CARS Reporting Issues Using GRID Approaches According to analysis above, there are nine material issues which will influence CARS porting of Western. The following paragraphs will try to analyses these issues with GRID approach. . 3 Economic Perspective due to the 6% increase in housing loan and the offset by the 1% decline in business loan. The decline in business loan indicated the unsatisfactory economic environment. The increase in housing loan indicated that Western had a very good relationship with customers. This could be verified by the increase of customer number which is from 11. 8 (millions) in 2010 to 12. 2 (millions) in 2011 . However, Western still failed to achieve some objectives in relation to customer service. For nonuser NAPS which seeks to measure advocacy of customers, SST. George and Western were ranked 1 and 4 respectively in 2011 amongst the major banks rather than 1 and 2. Furthermore, Western in New Zealand has not achieved NAPS scores of +1 for retail and -12 for business either. Therefore, customer service still needs to be improved. Table 3. 1: Net profits of Western 2011 $m 2010 $m 2009 $m Interest income 38,098 34,1 51 30446 Net profit attributable to owners of Western 6,991 6,346 3446 It can be seen from Table 3. 2 below, salaries and other staff expenses increased by $ 65 million compared to 2010. One factor that contributed the increase was the average salary increase of 4% from January 2011, which indicated that Western aimed to increase employees benefits. Equipment and occupancy expenses were $1,115 million, an increase of $33 million compared to 2010. The increase was largely associated with refurbishment and expansion of brand and ATM networks. Table 3. 2: Operating expenses of Western Salaries and other staff expenses 4,055 3,990 3,806 Equipment and occupancy expenses 1,115 1 ,082 926 2,344 2,439 Total operating expenses 7,406 7,416 7,171 1. Social Perspective As Western is a multi-brand company, different brands will have different ways to improve customer service and develop deeper customer relationship. For example, Western Retail Business Banking launched Local Business Sentiment Survey to give the companys business customers insights into local issues and the strategies to deal with them. However, Western New Zealand used new innovations to improve customer servic e. Western has made a very good process on their objectives this year to achieve gender equality. Western now has 37. 5% women on the leadership role compared with that of 35. 4% in 2010 and has been working hard to move awards its 40% goal. Western and business bank also provides women with education, information and networking opportunities. Western has improved the reliability of IT system significantly during 2011. The number of technology related outages has reduced by a further 40%, which made critical customer related systems now available for customers. For example, Western New Zealand adopted Smart Deposit machines and Cash Exchange machines, which successfully helped the company to reduce branch queues by 40%, in order to provide better customer service. Western needs to make its service more efficient and improve its products continually. By process improvements, Western has achieved the reduction of customer complaints by 42%. This is due to the efficiency of service which will reduce the waiting time of customer. Western also tries to develop more innovative products to make customers more satisfied. For example, the Altitude Platinum Card was awarded Smart Investors best full featured credit card and Canned was awarded five stars to the Altitude Classic/Gold/ Platinum and Earth Platinum cards in 2011. Western also cares much about employees education level. For example, Bank of Melbourne invested over 7,000 hours of training and development in all of the people. Western has a very high employee engagement. Annual Employee Survey indicated that our employees remain highly engaged, with the employee engagement in 2011 result up one percentage point to 81%. Encouragingly, the People Leader Index of Western has again improved and is now at 83%, placing us above the Global High Performing Norm of 82%. Table 3. 3 Community Investment 2011 2010 2009 Community investment Financial reporting basis ($m) 135 136 Community investment GRID reporting basis ($m) 155 116 One performance indicator of social responsibility is the community investment. It can be seen from table 3. , community investment increased significantly in 2011 compared with that in 2010 from GRID perspective. By comparison, from financial perspective, the community investment decreased slightly. However, if the company compares the data in 2010 and 2011 with the years before, it can be seen that the community investment increases significantly. 1. 5 Environmental Perspective The climate change is a global issue faced by all organizations. The amount of CA emission released by organizations is a very important factor which could be used to measure the companys corporate social responsibility. The process of replacing outdated equipments with more energy efficient ones helps Western to reduce the release of CA emissions, with the estimate of 1 5000 tones reduction during the year. According to CARS report of Western, total scope 1 and 2 emissions has reduced from 189,425 tones in 2010 18th,124 tones minion and total scope 3 emissions reduced from 70457 tones to 57163 tones which is a satisfactory result. The reduction of paper use from 6655 tones to 6262 tones contributed a lot to the reduction of emission. 4. Recommendation for Solutions and Explanation According to the behaviors that Western undertook to solve the CARS problems eased on GRID approaches, it seems to be the right way to achieve the ambition of CARS reporting like respect, sustainability and responsibility. 1. 6 Economic Perspective The actions Western took may decrease the profit in dollars in short term, but in long run, since Western tried to establish a strong relationship with customers as well as increase employees values, a lot merits may occur to underpin the profit generation process and achieve a sustainability of profit of Western. . 7 Social Perspective Based on analyzing the issues of suppliers, Western decided to do business with the appliers that comply with SCM in order to reduce the paper usage so that CA emission would decrease. It is a necessary way to discharge the responsibility of Western to protect the sustainability of environment, and helpful to sustain a long- term profitable development of the org anization. However, a problem occurs. Concerns only about one aspect of suppliers cannot help achieve overall sustainability of organization. For example, reducing the paper use for serving the The way to tackle it is caring about the relations among different stakeholders and trying to balancing them when there is conflict among each other. In terms of the aspect of customers, Western launched surveys, improved the reliability of IT systems, and provided services that are more efficient as well as changing product portfolio along with the changing tastes of customers, all these actions contributed to the sustainability of Western. Firstly, surveys identified customers preferences and Western was able to follow them in order to achieve a sustainable development. Secondly, advanced IT systems reduced complaint rates and enhanced efficiency helps retain customers, build reputation, saving resources and attract potential customers. Finally, launching different products according to different needs may enlarge the range of customers and increase the economic scale of organization. However, there is still a gap between the objective of rank 1 or 2 and the real situation, thus there should be a deeper analysis about whether Western did focus on certain customers rather than other else, which damaged the long-term development of organization. Western also concerned about employees sustainable development. It paid attention to equity of gender, education level and safety of working environment, which helped achieve the aim of CARS reporting of respecting he employees rights like equality, self-development and safety. In addition, since Western had done a lot in this area, employees may work even harder and stay longer in return, which contribute to the sustainability of organization. Additionally, Western invested a lot in communities so that money goes into different areas where needed and social sustainability can be improved. 1. 8 Environmental Perspective Finally, in relation to the environment aspect, Western endeavourer to reduce the emission of CA, which would assist in attaining the environmental sustainability.
