Obesity Could Be Catching

This article by Emma Woollacott entitled Obesity Could Be Catching, is a medical related article. This article tries to find obesity related issues leading to the infection of liver diseases.Advertising We will write a custom essay sample on Obesity Could Be Catching specifically for you for only $16.05 $11/page Learn More Briefly, the  article  clearly seeks to  illustrate reasons behind the occurrences of obesity and its side effects, for instance infections. Moreover, the article points out the way Yale scientist tested mice and found out that they could develop Non-alcoholic fatty liver disease. They also came to the conclusion that antibiotic treatment of mice could bring microbial composition back to normal. NAPLD can also be found in humans; 30 million people suffer from it in the United States. NAPLD leads to obesity and diabetes. Scientists hope they can find a treatment or cure for humans (Woollacott p. 1). They are eager to find a lastin g solution of the liver disease that has affected many people in the world. The article highlights the  process  carried out to  detect  how the microbes that cause obesity could be transferred from one person to the other (Woollacott p. 1). It is necessary to note that this is not  directly  administered to human beings. Given that it is an  experiment, scientists are keen on using animals first until facts prove that it is safe for human. It was clear from the experiment that the microbes causing the  disease  are contagious since the healthy mice kept with the  infected   were found  to be possessing microbes (Woollacott p. 1). Woollacott further indicates that there are  certain  proteins responsible for the development of an immune system. The  article  also gives the discoveries by the Yale University team on the presence of the same inflammasomes microbes that profoundly contribute to the liver disease known as the â€Å"non-alcoholic fatty li ver disease NAFLD† (Woollacott E p. 1). Woollacott  further  says that the experiments prove that this comes along with other disease such as diabetes being also a  serious  cause of the deadly liver infections found in the western world. The  article  gives statistics on the people who suffer from the NAFLD infections in the US only. It is  shocking  to  note  this is a serious threat to the future health. It  is estimated  that  approximately   30 million suffer from NAFLD. These people are at the risk of contracting cirrhosis and the liver cancer (Woollacott E p. 1). It is  alarming  that even  today  no reason  has been given  to this.Advertising Looking for essay on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Since  proper  research and documented  proof  is available, this  research  is valid. The statistics given in the article reflects a true finding. It i s my heartfelt  opinion  that permission should be granted for it to  move  to the next stage. Donors should be  willing  to  finance  the project since many Americans are at risk. Once the experiments  are done  on human and proved to be efficient, many lives  will be saved. The government should as well be willing to sponsor volunteers to undertake the experiments. Medical findings in America should be given priorities. Good incentives should be given to the devoted scientists to  keep  on the spirit of finding permanent health solutions for Americans. The experiments   done  on mice will be  positive since mice are mammals meaning that their  body  systems are similar to those of the human beings, which gives the scientists some confidence that  positive  results  will be obtained.

Rockefeller was seen by the public as a greedy, ruthless business man, usurping every oil refinery in the nation, pushing everyone out of business. Rockefeller sent out spies to be ahead of competitors, pushing them out of jobs, leaving familys penny-less. Rockefeller used the method of cheap materials, cheap labor and tremendous profits. In a matter of a few years J.D. controlled 90% of the world oil market. When his ruthless and inhuman tactics were discovered by the public he gave money to compensate, as if money could heal the pain caused to so many families and forgive him of all his sins. At last John D. Rockefeller held the position of his dreams the ruthless Chowder, destroying Americas economic diversity as the ruler of the vast Standard Oil empire. Among many things Rockefeller was know for his vast contributions to capitalism and the growing economy. Rockefeller started a oil refinery at a very young age and watched it grow into a lucrative chain of companies. Based on hard work and a God-given gift he followed his dreams by doing Gods work, making lots of money and giving lots away. Rockefeller was a very talented business man and made generous offerings to his competitors to take over their businesses in legal and ethical ways. He is one of the greatest know philanthropist of all time, he gave away millions of dollars of his hard earned personal wealth to charity, for science development, and churches. ...

The Tragic Love Story of Cybele and Attis

The Tragic Love Story of Cybele and Attis Cybele and Attis is the story of the Phrygian great mother goddess Cybeles tragic love for the mortal Attis. It is also a story of self-mutilation and regeneration. When Cybele- one of Zeus would-be lovers- rejected him, Zeus wouldnt take no for an answer. While his victim slept, the great philanderer spilled his seed on her. ( In due course, Cybele gave birth to Agdistis, a hermaphroditic demon so strong and wild that the other gods feared him. In their terror, they cut off his male sexual organ. From its blood sprang an almond tree. This castration/birth connection is also seen in one version of the story of the birth of Aphrodite. Attis Is Born to Nana The river Sangarius had a daughter named Nana who ate the fruit of this almond tree. When, as a result of her snack, Nana delivered a boy child 9 months later, Nana exposed the child. This was an ancient method of dealing with unwanted children that usually led to death, but did not in the case of such important figures as Romulus and Remus, Paris, and Oedipus. Infant death was not to be his fate, however. Instead, reared by the proverbial area shepherds, the boy soon became healthy and handsome- so handsome his grandmother Cybele fell in love with him. The First Violets The boy, whose name was Attis, was unaware of the love Cybele bore him. In time, Attis saw the king of Pessinus beautiful daughter, fell in love, and wished to marry her. The goddess Cybele became insanely jealous and drove Attis mad as revenge. Running crazy through the mountains, Attis stopped at the foot of a pine tree. There Attis castrated and killed himself. From Attis blood sprang the first violets. The tree took care of Attis spirit. Attis flesh would have decayed had not Zeus stepped in to assist Cybele in his resurrection. The Ritual of Attis Since then, a yearly ritual has been performed to purify the body of the dead Attis. The priests- referred to as Galli or Galilee- are emasculated in emulation of Attis. A pine tree is chopped down, covered with violets and carried to the shrine of Cybele on Mt. Dindymus. There Attis is mourned for 3 days. Then, when Cybele brings him back to life, there is a wild and joyful celebration.

Written Assigment II - Essay Example The one that enjoys a higher comparative advantage, for instance computers, should form the primary export while textile, whose production has a lower comparative advantage, should be imported from China (Frederking 3). In this paper, I hold a contrary view to Patrick Buchanan by supporting Ricardo’s theory. Countries chose to engage in international trade with a view of making profits. It would be totally illogical to engage in a business activity where there is no overall profit. As such, the driving force of international trade is the hope of maximizing profits accrued in the production of a given product. In this view, nations engaged in international trade strive to strike a balance by increasing the unit value they gain by exporting a given product. While this takes place, the same country would strive to reduce its engagements in products that do not earn as much profit as the others by the virtue of their production costs. Therefore, in an international trade, a country which exports gains more than that which imports. This is because exporting countries enjoy a favorable balance of payment than those which import (Ritchie 19). The utility derived from utilizing factors of production differs in the production process of different products. For instance, in the case of computers and textile products, it is evidently cleat that United States of America spends less per unit of factors of production when it concentrates on computers than when it concentrates on textile products. In this sense, U.S. is bound to increase its overall profit if it converts the factors of production used in the manufacture of textile products to the manufacture of computers. As such, textile industry becomes the opportunity cost of production of computers. Similarly, China is bound to increase its profitability if U.S. chooses to concentrate on importing its textile products. As such, free

Network Security Analysis Essay Example for Free

Network Security Analysis Essay This article is concerned about network security. It mentions about the present situation of network security and an analysis of the reason that lead to unsafe network environment. Then the article introduces two frequently used protocols in network security: HTTP (Hypertext Transport Protocol) and HTTPS (Hypertext Transfer Protocol over Secure Socket Layer), then compare them and give a brief conclusion. On the other side, the article introduces how firewall protects network security in hardware aspects. Keywords: Network; Security; Analysis; Countermeasures 1. Introduction As technology develops, network is getting more and more mature. It is known to all that security is the second step after that a successful network has been deployed. 1.1 Situation of Computer Network Security With the rapid development of the Internet and the widespread application, the number of computer viruses, Trojan horses is explosive growth. According to Jinshan drug gangsters cloud security center monitoring statistics show that in 2008, Jinshan drug gangsters were intercepted more and more new viruses, Trojans, which grew up 40% compared with 2007. The center statistics also show that 90% of the virus infected users, this attachment web pages that humans are enjoying the network information with the great wealth and convenient at the same time, also be the severe beset by problems of network information security. The lure of wealth that hackers attack is no longer a kind of personal interest, but more and more become an organized, interest driven career crime. Its main means has: online professor viruses, Trojan horses production technology and various network attack technology; Online exchange, trafficking and rental viruses, Trojan horses, zombie network; Online customized viruses, Trojan horses; Internet theft behavior (account Numbers game, bank accounts, QQ number, etc.), sell the trumpets; Internet fraud and extortion; Through the network business platform money laundering profit, etc. Attackers need technical level gradually decrease, means more flexible, joint attacks increase rapidly. Trojan viruses, Trojan virus writers, professional hack personnel, sales channels, professional players have been formed complete gray industrial chain. 1.2 Threats to Computer Network Security The threat to computer network security includes attacks by hackers and computer virus. It mostly presents in the following aspects. Firstly, send fake E-mails to users. It is a common way to cheat the account and password by posing as legitimate websites. Secondly, damage caused by viruses is also a common phenomenon. For e.g. when virus gets into computer, it will cover our hard disk with useless data. Thirdly, it’s about unauthorized accessing. This mainly refers to the normal use or oversteps their authority to use the network equipment and information resources. Fourthly, damage the integrity of the database. Fifthly, interfere with the normal running of the systems. Finally, communication lines are tapped and people are not familiar about safety of network security. The first situation doesn’t occur in common. However, awareness of maintain computer network security is really important. In the article, it mainly analyzes several common situations and introduces what the threat is and how it works. 1.3 Countermeasures of Network Security As network security has a lot of loopholes, people create a lot of methods to protect network. On the side of hardware, people begin to use firewall to protect network. On the side of software, a lot of tools and technologies have been used in this area, such as router filtering. The article introduces how firewall works and two similar protocols: HTTP and HTTPS. By comparing these two protocols, we will find the development of technology. 1.4 Importance of the Study of Network Security It’s important for securing ones computer, keeping important data and profile information protected. Careful web surfing habits may keep you from being a victim of virus attacks and malware, however this is an intensely risky activity and very often people may end up with an infected computer. Some good anti-virus programs will help to keep your computer protected and safe, but users must remember to keep this updated regularly for better protection over new viruses. 2. Related Work 2.1 Network Security Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: It secures the network, as well as protecting and over seeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password. 2.2 ISO/OSI model The International Standards Organization (ISO) Open Systems Interconnect (OSI) Reference Model defines seven layers of communications types, and the interfaces among them. (See Figure 1.) Each layer depends on the services provided by the layer below it, all the way down to the physical network hardware, such as the computers network interface card, and the wires that connect the cards together. People develop a lot of protocols to each layer. Such as PPTP/L2TP to linked layer, IPSEC to network layer, TLS/SSL to transfer layer. Each protocol includes security information that helps network transfer safer and safer. 2.3 IPV4 protocol The protocol contains a couple aspects which caused problems with its use. These problems do not all relate to security. They are mentioned to gain a comprehensive understanding of the internet protocol and its shortcomings. The causes of problems with the protocol are: 1. Address Space 2. Routing 3. Configuration 4. Security 5. Quality of Service The lack of embedded security within the IPv4 protocol has led to the many attacks seen today. Mechanisms to secure IPv4 do exist, but there are no requirements for their use. IPsec is a specific mechanism used to secure the protocol. IPsec secures the packet payloads by means of cryptography. IPsec provides the services of confidentiality, integrity, and authentication. This form of protection does not account for the skilled hacker who may be able to break the encryption method and obtain the key. 2.4 Types and Sources of Network Threats Denial-of-Service, unauthorized access, executing commands illicitly, confidentiality breaches and destructive behavior are common type of threats to network security. The sources of network threats include 3 aspects. Firstly, the invasion of bad information and pollution. Network is open, even borderless space information network of people in the rich cultural life, but also to the illegal dissemination of information or indecent information provided soil British Middlebury Seck Griffith University, Professor Di Mulai study found that in non-academic information on the Internet, 47% of pornography on These content without restriction for people feel free to browse, not only seriously jeopardize the health of young people, and poison the social atmosphere and hinder the building of a harmonious society in China. In addition, the networks openness and freedom are often some criminals use, or dissemination of endangering national security, to subvert the government, disrupting social order and security of information, or information network organizing rallies and other anti-social activities. Secondly, Internet hackers and computer crime. Hacker wanton rampage information networks, technology and the consequences of its invasion of escalating their use of technical means, or attacks on government sites or military organizations Web site and endanger national security interests, undermine government image; or steal business, financial institutions, business information to profit illegally, endangering the economic order; or steal personal confidential information, violation of privacy or stolen cash. These acts seriously impede the normal operation of information networks. In addition to outside hackers the use of the Internet, the rampant crime and tort. The use of computer information network system to implement theft, fraud or corruption, embezzlement and other crimes than the traditional criminal methods and tools more subtle complexity, and violation of trade secrets with the network, electronic communications freedoms, civil Privacy and damage the reputation of others and other events are also frequent. Online pyramid schemes, online fraud, etc. These crimes have been on the network posed a serious threat to network security. Thirdly, the existence of their own network security vulnerabilities and risks. Freedom to share and open spirit of the Internet, but also the charm of the Internet The Internet is based on TCP / IP protocol, network devices, operating systems with networking capabilities and openness about the existence inherent vulnerability In addition, the software in the design, it is inevitable there are some defects or flaws, which has become a prime target for hackers, while software programmers deliberately left the back door has become a major network security risks network These weaknesses of their own existence, to bring the work of anti-hacker considerable difficulty: on the one hand difficult for scientists to develop a common and effective network security for the protection of technical means on the other hand the lack of implementation of these measures sufficient to protect the social environment. 3. Methods 3.1 Analysis of Network Security System and network technology is a key technology for a wide variety of applications. Security is crucial to networks and applications. Although, network security is a critical requirement in emerging networks, there is a significant lack of security methods that can be easily implemented. There exists a â€Å"communication gap† between the developers of security technology and developers of networks. Network design is a well-developed process that is based on the Open Systems Interface (OSI) model. The OSI model has several advantages when designing networks. It offers modularity, flexibility, ease-of-use, and standardization of protocols. The protocols of different layers can be easily combined to create stacks which allow modular development. The implementation of individual layers can be changed later without making other adjustments, allowing flexibility in development. In contrast to network design, secure network design is not a well-developed process. There isn’t a methodology to manage the complexity of security requirements. Secure network design does not contain the same advantages as network design. When considering network security, it must be emphasized that the whole network is secure. Network security does not only concern the security in the computers at each end of the communication chain. When transmitting data the communication channel should not be vulnerable to attack. A possible hacker could target the communication channel, obtain the data, decrypt it and re-insert a false message. Securing the network is just as important as securing the computers and encrypting the message. When developing a secure network, the following need to be considered: 1. Access – authorized users are provided the means to communicate to and from a particular network. 2. Confidentiality – Information in the network remains private. 3. Authentication – Ensure the users of the network are who they say they are 4. Integrity – Ensure the message has not been modified in transit 5. Non-repudiation – Ensure the user does not refute that he used the network Here we mainly discuss fake websites. Fake websites means phishing. Phishing is attempting to acquire information (and sometimes, indirectly, money) such as usernames, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public. Phishing is typically carried out by e-mail spoofing or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Phishing is an example of social engineering techniques used to deceive users, and exploits the poor usability of current web security technologies. Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical security measures. Once a victim visits the phishing website, the deception is not over. Some phishing scams use JavaScript commands in order to alter the address bar. This is done either by placing a picture of a legitimate URL over the address bar, or by closing the original address bar and opening a new one with the legitimate URL. An attacker can even use flaws in a trusted websites own scripts against the victim. These types of attacks (known as cross-site scripting) are particularly problematic, because they direct the user to sign in at their bank or services own web page, where everything from the web address to the security certificates appears correct. In reality, the link to the website is crafted to carry out the attack, making it very difficult to spot without specialist knowledge. Just such a flaw was used in 2006 against PayPal. A Universal Man-in-the-middle (MITM) Phishing Kit, discovered in 2007, provides a simple-to-use interface that allows a phisher to convincingly reproduce websites and capture log-in details entered at the fake site. To avoid anti-phishing techniques that scan websites for phishing-related text, phishers have begun to use Flash-based websites. These look much like the real website, but hide the text in a multimedia object. 3.2 Firewall’s Protection A firewall can either be software-based or hardware-based and is used to help keep a network secure. Its primary objective is to control the incoming and outgoing network traffic by analyzing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set. A networks firewall builds a brigade between an internal network that is assumed to be secure and trusted, and another network, usually an external (inter)network, such as the Internet, that is not assumed to be secure and trusted. In general, some functions that can be done by the firewall are: 1. Doing a packet filter firewall can make the decision whether to accept or reject the incoming data packets. 2. Hiding Network Address (NAT) IP addresses can be used on the internet is a public IP. So to create a client that uses private IP can be translated into public IP. These functions are performed by a firewall, known as NAT. 3. Monitoring and Logging to improve network security and logging on the terms monitoring by a firewall. 3.3 Protocols of Network Security Network security protocols are used to protect computer data and communication in transit. The primary tool used to protect information as it travels across a network is cryptography. Cryptography uses algorithms to encrypt data so that it is not readable by unauthorized users. Generally, cryptography works with a set of procedures or protocols that manage the exchange of data between devices and networks. Together, these cryptographic protocols enhance secure data transfer. Without cryptographic network security protocols, Internet functions such as e-commerce would not be possible. Secure communication is necessary because attackers try to eavesdrop on communications, modify messages in transit, and hijack exchanges between systems. Some of the tasks networks security protocols are commonly used to protect are file transfers, Web communication, and Virtual Private Networks (VPN). The most common method of transferring files is using File Transfer Protocol (FTP). A problem with FTP is that the files are sent in clear text, meaning that they are sent unencrypted and therefore able to be compromised. For example, many webmasters update their sites using FTP; an attacker using a packet sniffer and the website’s IP address can intercept all communications between the webmaster and the site’s server. Here we mainly discuss two similar protocols: HTTP and HTTPS. The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Hypertext is a multi-linear set of objects, building a network by using logical links (the so called hyperlinks) between the nodes (e.g. text or words). HTTP is the protocol to exchange or transfer hypertext. The standards development of HTTP was coordinated by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), culminating in the publication of a series of Requests for Comments (RFCs), most notably RFC 2616 (June 1999), which defines HTTP/1.1, the version of HTTP in common use. Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol (HTTP) with the SSL/TLS protocol. It provides encrypted communication to prevent eavesdropping and to securely identify the web server with which you are actually communicating. Historically, HTTPS connections were primarily used for payment transactions on the World Wide Web, e-mail and for sensitive transactions in corporate information systems. In the late 2000s and early 2010s, HTTPS began to see widespread use for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and browsing history private.

Should Chinas Human Rights Record Prevent Permanent Normal Trade Relations :: Human Rights Essays

Background Since the initial warming of U.S.-China relations in the early 1970s, policymakers have had difficulty balancing conflicting U.S. policy concerns in the Peoples' Republic of China. From Nixon to Clinton, presidents have had to reconcile security and human rights concerns with corporations' desires for expanded economic relations between the two countries. While the U.S. regularly objects to China's human rights violations, the Chinese government counters with complaints that the American concerns represent unwarranted American intrusion into its internal affairs. In 1989 the Tiananmen Square massacre drew public attention to the inconsistent character of U.S.-China policy. A wave of public indignation with China's repressive practices forced the Bush administration to adopt a sterner posture toward human rights violations and to impose sanctions, including restrictions on bilateral and multilateral aid. But these measures have not satisfied some critics of China's human rights practices, who contend that the U.S. should apply even more rigid trade restrictions against China. Specifically, some critics insist that the U.S. government not give China "permanent normal trade relations" status, which would free China's government from an annual review of its human rights record by Congress. Many critics say PNTR standing should be linked to improvements in China's human and labor rights practices - a policy that has been rejected by the Clinton administration. Rather than denying China normal trading status because of human rights violations, the Clinton administration has opted for a policy of "comprehensive engagement," which holds that long-term U.S. goals such as human rights improvement are more likely to be achieved through sustained contact and open trading than by further isolating China. Yet Chinese human rights practices, including respect for political and labor rights, continue to fall well below internationally accepted standards. In perhaps the stickiest issue, the White House warned last week that there was little chance of PNTR for China without legislation setting up a watchdog commission to monitor Beijing's human rights practices. China, however opposes any plans by the U.S. to monitor human rights as a condition to granting PNTR. On One Hand... American businesses should not be coddled at the expense of human rights. Despite expressions of concern for human rights conditions, the U.S. government has allowed narrow economic interests, particularly those of corporate investors, to guide its China policy. So far, the U.S. government has been unwilling to jeopardize U.S. economic relations by adopting stricter human rights conditions on aid and trade. China's trade status is currently reviewed annually by Congress.
