Inventing A Writing Technology :: Teaching Writing Education Essays
ââ¬Å"Inventingâ⬠A Writing Technology When we originally were given the criteria for this assignment, I knew right away what it was that I was going to do. I love being creative and sharing my ideas with other people, I like to think of myself as somewhat of an original person. My idea would initially satisfy all of the given criteria: permanence, portability, creativity, and naturalness of the components used to compose my creative piece of writing. Growing up, my brother and I would venture out when the creek was frozen and play on the ice for hours on end. One of the things we would do was carve out the ice to make picture, games and such. I knew that for his project, using ice would be an excellent idea. I knew it was fairly easy to do, it would stay there for as long as the creek continued to be frozen, and if necessary, it could be cut out and taken along to wherever I needed to go. When I arrived at my parentââ¬â¢s house, I headed straight for the creek with the plan in mind only to find that the ice was snow covered. I was down, but not out. After shoveling the ice, I was ready to begin my carving only to find that the ice was bubbly and definitely not smooth enough to be a recognizable writing surface. My plan was shot, I had come home for nothing. From this point on, I was forced to come up with an alternative plan of action. I thought of many things to use such as sticks and stones, but they would all sink into the snow if I placed them there and where not very portable or permanent if laid upon the ice. After weighing my options and a great deal of thought, I caught a glimpse of one of the many trees that line my creek bank. On the tree were many jagged icicles one of which I decide to use as my writing tool. My surface became the dreaded snow that was the culprit behind my initially foiled plan.

Al-Qaeda Training Manual
The US Department of Justice (US DOJ) has publicly disclosed the ââ¬ËAl-Qaeda Training Manualââ¬â¢ which was recovered from the house of arrested alleged terrorist Khalid Khaliq on July 2005 in Manchester, England.The training manual containing comprehensive chapters of lessons written in Islamic language has been translated in English; following US DOJââ¬â¢s handling of a trial on the spate of terrorist attacks of the UK and the US vital installations (US DOJ, 2008).Accordingly, to cite, the training manual outlines four substantial topics, such as (1) Lesson 1: Principles of Military Organization, (2) Lesson 2: Necessary Qualifications and characteristics for the Organizationââ¬â¢s Member, (3) Lesson 3: Counterfeit Currency and Forged Documents, and (4) Lesson 4: Organization Military Bases (US DOJ, 2008).In this paper, the position of a counterterrorism specialist will be discussed, relating the hypothetical questions on what implications for counterterrorism are conta ined in the training manual and what counterterrorism strategy can be developed in light of the manual.Implications for counterterrorismAs a point of view on the classification of the training manual as a ââ¬Å"captured documentâ⬠, counterterrorism specialist may critically consider two fundamental implications for counterterrorism, such as (1) revalidation of the captured document, and (2) operational review on counterterrorism strategies. This critical reconsideration underscores the ââ¬Å"way of the systemsâ⬠in assessing the counterterrorism campaigns in both military and civilian organizations.Revalidation of the captured document would exert extensive effort for key military units and the intelligence community to analyze the veracity of information contained in the training manual.The first scenario to implement the revalidation could be in the field personnel, like the CIAââ¬â¢s HumInt (human intelligence) clandestine operatives that verifies and classifies th e ââ¬Å"substantive categoryâ⬠of such information. The second scenario could be the ââ¬Å"analytical methodâ⬠, examining the depth and breadth of the captured document in the aspect of strategic purpose and intent; referring to the psychological warfare (psywar) of the literature.The operational review on counterterrorism strategies could be in line with redefining and reformulating short and long term plans or tactics purposely ââ¬Å"to counterâ⬠the operation plan or ââ¬Å"OPLANâ⬠that can be found in the training manual. Overall, the implication would take into effect the enactment of policy framework that deals with counterterrorism.Counterterrorism StrategyAs cited from the training manual, Al-Qaeda massively recruits individuals working in borders, seaports and airports, of which will carryout the mission to blast or destroy vital places, like public amusement centers, embassies, economic zones, communication and media establishments, and government an d military facilities to name a few (US DOJ, 2008).Given the above situation, the first employment of a counterterrorism strategy is to secure the possible, potential and vulnerable places for terrorist attacks. One aspect of security measures is through ââ¬Å"personnel profilingâ⬠or the conduct of evaluating the profiles of working personnel and monitoring their activities. In which case, a security guideline must be decisively implemented in working areas.However, the counterterrorism strategy can be efficiently and effectively implemented without legal constraints by implementing the necessary, existing and applicable laws, regulations and state policies that are meant to safeguard the working places and promote lawful prevention against terrorism. Thus, mobilization of strategic counterterrorism campaigns can be implemented at the extent of public tolerance and compliance.On the other hand, it is a common knowledge that the US Naval facility in Guantanamo, Cuba has been u sed as a prison of arrested terrorists, in which the controversy of alleged inhuman treatment of prisoners has recently ordered by President Barrack Obama to ââ¬Å"dispose of utilizing the facility as a torture denâ⬠.By mentioning this information, it owe to relate the situation that counterterrorism specialist or expert may rely on applying psychological and physical torture as a method to ââ¬Å"extract informationâ⬠or obtain it as a first-hand validation from detained terrorists, partly of the strategy in reaffirming the information which is also called by the intelligence community as ââ¬Å"renditionâ⬠.

Literature Review on Types of Discipline Essay
2.1.1: Vandalism According to article ââ¬ËWhat is vandalismââ¬â¢, written by Dye1, she defined vandalism as a crime that generally involves the destruction, disfigurement of public or private property. A person does not have to destroy a property to be charged with vandalism. This crime can include acts that simply demise a piece of property. For example, a person may rip the seats of a school bus. The bus is still operable, but its value and its ability to be used are greatly reduced. Kraus (1979) said that vandalism consequences are often simply causing trouble and anger. One aspect of school vandalism is often reported in research studies from the United States as the research from Rubel (1977) states that the connection of vandalism with other types of school crimes such as petty theft in the school and personal violence against staff and students. According to Cohen (1973) the public sees this type of behavior as threatening. Even though vandalism is directed at public property, the public still feared being victims of uncontrolled juveniles that roaming the street. 2.1.2: Absenteeism Then, Heathfield2 defined absenteeism as the chronic absent from work or study. Absenteeism usually addressed through progressively stricter disciplinary measures that can result in the termination of the individualââ¬â¢s employment. This is generally governed by the institution attendance policy. Rayner & Riding (1996) cited Schostak (1980) in the United Kingdom that found at least 800,000 students absent from school for unexcused reasons. Webb (1993) suggest that approximately half a million students were absent each day. Students who have absenteeism problems generally suffer academically and socially. According to Baker and Jansen (2000), studies indicate that students who are absent have lower achievement and may be penalized on test scores. Sustained absences may lead to retention and truancy. _____________________________________________________________________________________________________________________ 1 http://www.wisegeek.com/what-is-vandalism.htm 2 http://humanresources.about.com/od/attendancepolicy/g/absenteeism.htm 2.1.3: Truancy Wisconsin (2000) defined simple truancy as any absence of part or all of a school day for which a pupilââ¬â¢s parent or guardian has not provided a valid excuseâ⬠. According to Cavallari3, he states that many institutions throughout the world have difficulty enforcing mandatory attendance for a variety of reasons. Some students find it more worthwhile to enter the world of career and earn money for their families, while others struggle with coursework and choose simply not to attend class while others have difficulty getting to school because they live in rural areas. The reasons why students do not attend school are complex and seemingly endless, making mandatory attendance difficult to enforce. Some schools base part of a studentââ¬â¢s grade on attendance, while others make an attendance percentage a requirement for graduation. A student must attend classes a certain percentage of the school year in order to advance to the next grade as the student can be held back in the same grade if he or she fails to meet compulsory attendance requirements, which some critics claim can discourage students from attending school at all. However, some advocates claim it encourages students to attend class because it means they can progress to the next grade level with their peers. 2.1.4: Smoking Henderson4 and her colleagues found that in their research about smoking habits and wider social environment in school, on average, 25% of males and 39% of females aged 15-16, reported that they either regularly or occasionally smoked. The age group of 14 to 18 years is most likely to attract towards the smoking habit and become an addict for the rest of his or her life as this age represents the growth of maturity where teens make choices for their life style and plan where they want to see themselves in the future. The teens are more conscious about their personality, styles and making up their role model as their inspiration in life. On the other hand, this is the age where factors like stress, attention disorder, psychological pressures and conflicts from parents play an important role in impacting the individual personality and most of the teens are seen fighting with these kind of problems due to lack of parental interest, or sometime over protectiveness of parents. _____________________________________________________________________________________________________________________ 3 http://www.wisegeek.com/how-can-schools-enforce-mandatory-attendance.htm 4 http://www.journal-archieves14.webs.com/848-855.pdf

Women Have Evolved
Women have come a long way in America. They used to not be able to vote or stand alone with major decision that had to be made. Now they are so many advantages for women living in our society and now thank god these advantages are now rights to women of America. Women in the USA have taken advantage of these new right and exceled with them to become better individuals. Women in America have advantages because there are now contraceptives to prevent pregnancy, more women are able to go to school and get education, women now hold their own jobs and women are getting married at an older age because they are now independent. Contraceptives have become a must have for women in the United States. This great for American women because in past there were no contraceptives, women would get married and have many children because lack of birth control for them. Some women would have what they call mistakes, because of one night stands and be stuck with a baby they were not ready for. Women are now able with the help contraceptive to choose when they want to get pregnant and when they just want to wait till the time is right. Women have took advantage of being able to control getting pregnant and are now having children at older age, when they feel more mature and ready to have children. Women used to have to stay home in take care of their children. Most women in America would be lucky if they were even able to get a high school diploma. Men back in the days did not want their woman to further their education, but now with new advantages women have started excelling and going to college. They started to realize that they could still have a family and graduate from college. Women are taking their education seriously and now succeeding in college due being given the privileged attend college. As stated by whitehouse. gov ââ¬Å"Womanââ¬â¢s gains in educational attainment have significantly outpaced those of men over the last 40 yearsâ⬠(para 5). Woman worth in this economy had started to become recognized in the United States. More women have started graduating from ollege and not stopping at high school because of starting a family. Because our society have given woman a chance to get a higher education there scores on test , classes and graduated rates have passed up the men in America. The Economist wrote ââ¬Å"Women in the United States earned 60%of university degrees in Americaâ⬠(para 3). Now that women are able to work and not told to stay at home and watch after their children they are doing good in the workforce and able to obtain work that before was only able to be obtained by a man. The Economist stated ââ¬Å"They run some of the worldââ¬â¢s best companies, such as PepsiCo, Archer Daniels Midland and W. L. Gore (Para 3). Women are more independent with having their own jobs and do not depend on men to take care of them. Some women have had to step to the plate so that they could have a two income home and make in this new society in America. According to the Economist ââ¬Å"Women now make up almost half of American workers (49. 9% in October)(para3).

A analysis of Google quit Chinese market
Fourthly, the conflict between Google and Chinese government had upgrade to diplomatic emissions, the wise was both of two government solve this problem in intellect way. 2. 0 The company profile of Google Google is an American multinational corporation, which is worked on Internet service including search, cloud computing software and online advertising. The mission and vision of Google is to organize the world's Information and make it universally accessible and useful. As the culture of Google, they hire smart and determined people.Its employees share common goals and vision, but they hire people from all over the world. When they are not work, the offices environment like home and It Is leased. They have open culture, make every contributor feel comfortable. (Google, 2014) 2. 1 The introduction of Google's problem encountered in China The most of obvious problem is Google have conflict with Chinese government. At the beginning, Google was not obeyed Chinese Internet Censored regu lation. But under the pressure of Chinese government, Google tried to cooperate that is not approved by Chinese government, but it did arouse against in the rest of world.A internal problem from Google is they did not understand Chinese culture and language which make search engine Inefficiency. Google's business had been taking from Its competitor?Bald. According to high level report (San, 2007, p. 6) 3. 0 Evaluation of the Inter personal relationships affects the corporation's profit in China Interpersonal relationship means a strong, deep, or close association between two or more people. The interpersonal relationships are formed in the context of social, cultural, traditional and other elements.For most of people, they are likely to feel non-treatable with foreigners, which is hurting international business. Such as Google, it entered China as foreigners, it hard or Google to open Chinese market. Therefore, inter personal relationships allow build trust or even friendship, which is beneficial to corporation's business. Furthermore, Inter personal relationships allow International corporation know the local culture, which Is good for communication. Inter personal relationships can eliminate the barrier In communication, and offer high efficiency and unblocked communication and in respect way.Google do not know the Chinese culture and instead of English. Google did not realize it, its functions of mandarin is weak, so seers cannot get satisfy answer by Google search engine. Interpersonal relationship is based on culture, it is seemingly more vital in China than any rest of countries. The inter personal had been becoming indispensable social element which ensures social function operation, since thousands years ago, inter personal tradition had formed. The foreign corporation effort to enter China market, it is important to learn this culture.Apparently, Google did not figure out this issue, they did not understand culture, and try to use their successful exp erience in America to open Chinese market. They make their business operation too professionals and cool, which betrayed Chinese culture. Because the misunderstanding Chinese situation, they are not favorable for Chinese net citizens. Compare with national brand Baud, the local business are deeper understanding Chinese situation, Baud occupies more market than Google. For example, Baud has many functions which is understanding Chinese culture.Such as Baud Zooidal, it provides a platform to let Internet citizen ask question and answer. And Baud Tibet is very suitable to Chinese Internet citizens, they can communicate on the Tibet. Agreeably, it gathers the people who have common point. Furthermore, Baud search engine understands Chinese language, so user are easy to access what they want, but Google not. (Edward, 2010) Not only the Chinese business men work rely on inter personal relationships, but also are international corporations necessary have good relation with government and a uthorities.The good relation with government official provides the good communication that make international corporations deeper understand local regulations. It is helpful to international corporations which is not adopted Chinese environment to change and transform. However, Google are too late to realize this, they had been trying to work on Internet freedom and try to build this as brand image in first several years entered China market. The brand image was not successful as they expected. With the Baud's rise, Google had been losing market share, and having trouble with Chinese government.According high level report (John 2011, p 1) Hence, it is easier for Google to operate it businesses, if they have good inter personal relationships network as international corporations. It can allow the opportunities and bring profit. Without inter personal relationship is hard to move on in China, but friends can impart experience and help. As long as international corporation build good i nter personal relationship, they are likely to access success and harmony cooperation relations. According high level report (David, p 3) 4. Chinese Internet Management Begun in 2003, Chinese government built the Great Firewall, it can block some foreign websites and surveillance of the network. Any uncensored Internet information is found that will be immediately deleted or shielded. Strength of monitoring program A, Contain the Internet violence B, Contain the Internet rumor C, Keep harmful content away from child A, It impose restriction on Google information B, It hurt human rights and make Google be debatable. 4. 1 The strength of monitoring program In China, the Internet violence has been overflow, which can be controlled by program.A behavior called ââ¬Å"Human flesh searchâ⬠This action allows net citizens to dig up another net citizens' private information including real name, address, hand phone number, his employer and so on. The Chinese official and social expertis e judge this behavior is Internet violence and guilty. Hence, they persisted monitoring program which contained this behavior. ââ¬Å"Human flesh searchâ⬠did hurt huge number of people. Some person had action which is unaccepted to other net citizens. The latter would use ââ¬Å"Human flesh searchâ⬠dig up their information, and abuse, threaten the victims.And it also infringes upon citizen's legal rights, such as right to privacy. Meanwhile, the Great Firewall can intercept dirty language, personal abuse. In some degree, it does refine the Internet environment. The circumstance can be controlled by government. Google is so powerful and it search engine can be this crime's accessory. It is refine the environment of Google. So, for Google, this monitoring can help Google find the crime information, it is good for Google development. (ROB, 2012) The Internet rumor has been overflow, which also has been keeping down by the program.In China, the Internet rumor is seemingly wo rse than any rest of countries. Rumor disrupts normal social order and brings about panic, riot, which is immorality. The government has duty to crackdown on online rumors to give citizen a truth. The radical content can be kept away from children. Some information is ultra, which s full of violence, pornographic, and poison. The child can easily access that information. The appropriate management is benefit to child. The parents are not worry about that children read bad information. (Shannon, 2013) 4. The weakness of Internet management The monitoring system is so strong that cover whole Internet, it can surveillance privacy, stop information, shield search engine. Chinese government use it prohibit many things. It is violate human rights. In China, it is hard to separate the politically- motivated Internet management and protecting legitimate citizen's interest. The overspent takes advantage of the monitoring system to achieve political motivation. The content harmful government but it is truth can be intercepted. It is good for government to shield and cover truth.The research engine cannot provide information to Chinese citizens without government censored. Google is an organization which believes the Internet information freedom, it provide some information which can be harmful to Chinese government. The government use law And it is ruining Google's reputation. (Suburban, 2013) Google cannot provide some websites which are not allowed to access in China, such s Faceable and Youth. Chinese governments and authorities stop these websites from citizens. It does puzzle citizens to use Internet.On another hand, the pirate and tort information is full of Internet in China, the monitoring system like blind and no operation to this crime. Google pay attention on copyrights, but its competitor is not at all. In China, Baud which is the biggest competitor have been offering pirate and tort information under the monitoring system. The authorities are conniving nati onal corporation Baud and cause problem with Google that reduce its competitiveness. And net citizens are prefer Baud in China. According to high level report Anyone, 2011,p. 12) The censored system is so restrict that many useful information had been deleted.Google provides some acknowledge and ideology which also are prohibited, such as some chemistry principle, explode principle, and firearms acknowledge. The Chinese officials believe it can ensure society stabilization. ââ¬Å"There are no explode, because no one can make itâ⬠It does puzzle learners have right purpose. Not only it violates human rights, but also does it perplexes Google operation. Google as requested to upgrade system to manage information and corporate the Great Firewall. Liking other Internet Corporation in China, Google had to invest huge sums on develop its monitoring systems.It wastes money and time, it reduces the corporation competitiveness. Furthermore, when the Great Firewall updating, these corpo ration business including Google can be affect. The condition of Internet become Jam and slow. (ROB, 2012) 5. 0 The importance of CAR in maintaining corporation international The CAR means the relationship between global corporations, government of countries, and individual people. The relationship between local society and corporation also is important. And the relationship between corporations with its stakeholders also cannot be forgotten.The stakeholders mean those effect corporation police and practices. Sustainability, the resource on the earth is limited, and corporations are the part of society. Hence, it is concerned that corporation how to use resource. As an international corporation, it behavior would be concerned, and public concerned its use of resource. It more likes morality restraint. And corporations pay attention on resource utilized which is responsible to society. Furthermore, sustainability not only about means resource, but also carrying capacity of the ecosys tem. Global corporations should concerned developing with care protection of ecosystem.They are powerful and taking more responsibility. The society is sustainability development and they can sustainability development. According to David (2008, app) concerned CAR is apparently important. The good action can build good brand awareness, such as charity. The media will help to advertise these beneficial actions, which is more worth that advertisement and promotion. (Craig, 2003, p. 21) For example, in China, Struck donates 1. 5 million US Dollar for training west rural teachers in poor areas, furthermore, this program also support poor students to finish their college study.Moreover, Struck are working on Education in China and Struck are the partner with women's Development Federation and Water and Sanitation Education Project. So, it is the reason of Struck is welcome in China. (Struck, 2006) 5. 1 The advice to Google Google have the privacy issues. As a global corporation, this pro blem had been across many countries. Marc believes that Google violate the global privacy tankards, and those issues are becoming as amusing as serious. Hence, the advice is respected the people's privacy right.It is important to build brand image to public, if Google hurt customer's privacy, which one are likely to use Google. And the different areas have different regulations of privacy, as a globe corporation, it is important to follow those different rules. Internal Google, they can set up a program to check any content that violent privacy. It is too late if external point out this behavior, which can quickly spread to world by media and bring harmful effect. According to high level report Anyone, 2006, p. ) The second advice is keeping away from China. It has a big share of search, in China.Chinese government insisted to censoring search content. Google had been agreeing with this censoring, but it against by rest of world. They believe the monitoring had violated the human ri ght. And the Chinese government still believed Google against the law under the cooperation. The censoring was betrayed Google's principle that respects Internet freedom and reality. Keeping cooperation would arouse the more oppose, including, Human right organization, reporter without burden and so on. In 006, some of demonstrator had the activity called ââ¬Å"Mass Breakup with Googleâ⬠.This activity protests the Google's cooperation with Chinese government. And demonstrators believe that Google break own principle of ââ¬Å"Don't be evilâ⬠. Away from China, and refuse cooperation can build good brand image to rest of world, and the operation still work in Hong Kong. According high level report (Bassoon, 2007, p 10-15) 6. 0 The suggestion to lessen the political vulnerability between the government of USA and China There are many, complex, and rottenness conflicts between two countries. The deepest conflict is in ideology. China is governed by the communist party which b elieves the socialism with Chinese characteristics.Obviously, United States of America is the leader of capitalist countries. Both of two have so much difference in belief. Hence, it related and cause the specific conflicts. The biggest answers were requested censored by Chinese government. The international social believe it betray the principle of freedom of Internet, in further, it violates human rights. Although, Google effort to cooperate with Chinese government, the latter still believe Google default and provide porn information. In the Google sides, they assert hey suffer from Chinese hacker Internet attack.USA government requires Chinese government to protect the rights of Google. Yahoo can work in China, because it respects the Chinese regulation. Yahoo has totally legal operation in China. Yahoo is taking responsibility of CAR. Both of China and USA better keep calm. In front of the conflicts, both of two governments better keep restrain action and speech. Between two lar ge countries, they have to think about the long-term benefit and cooperation. Impulsion and extreme action will hurt long-term cooperation relations. As Google's issue, it is a commercial issue. The suggestion is keeping it to commerce problem.The public social can query Chinese government's strategy of treat Internet information. But, it is not smart for USA, as a government to interfere China internal affairs. It is not smart way to upgrade this issue to political problem that is making problem more complex. The deep communication and understand the culture and custom. Through the communication, both of sides can solve this issue in negotiations and dialogue. USA government can understand Chinese conditions and troubles. There are reasons for censored Internet information. USA government can figure out these reasons before action.Meanwhile, it is important to protect Google's right. Chinese government should investigate Internet attacks. Such as Yahoo, it also has business in Chin a, and it can have a good relation with Chinese government. Yahoo respects Chinese regulation, and the government has no issue with Yahoo. The communication is important to understand the policy of government. 7. 0 Conclusion For many reasons, Google had quite China in 2011. Corporation put website into Hong Kong, which is last part business in China. The biggest reason is Google misunderstanding of China situation.Without consider inter personal relationships, the wrong evaluation was hurt Google in China. The shortage of understanding language make search engine work inefficiency. The market share was declined in big degree. The conflicts with Chinese government were upgrading. The cooperation with Chinese government was suffering against with rest of world. In awkward situation, quite might be the best choose, it still can be helpful to build brand awareness to rest of world. As the conflicts had been caused the diplomatic tensions, the suggestion was that both of governments sol ved this issue, which better noninsured the long-term interest.

Critique of an article Essay Example | Topics and Well Written Essays - 750 words
Critique of an article - Essay Example The article covers various aspects of astrocyte functioning in association with experimental basis on hippocampus cultures, cell cultures and imaging techniques. Interesting observations have been elaborated with regard to the calcium waves phenomenon and consequences of release of glutamate. Back in 1894, Rudolf Virchow referred to astrocytes as "glia", meaning "glue", as they were believed to be holding the neuronal elements together. Astrocytes: neuron ratio is approximately 10:1 and despite the larger number of astrocytes, it was neurons that were considered to perform the primary function of the nervous system. The increase in intracellular Ca[2+] level led to release of glutamate which in turn helped in modulating synapses to allow the conduction of the nerve impulse. The article, which spans over 14 pages, indeed provides a thorough, detailed insight in the working of astrocytes. It commences with a short description of the previously built information regarding astrocytes, and gradually gravitates towards the new findings regarding the functioning of astrocytes ... rding the functioning of astrocytes due to elevated intracellular calcium level as a result of various neurotransmitters like GABA, ATP, and glutamate. It has been brought forward that a calcium elevation in astrocytes is both necessary and sufficient to modulate synaptic transmission and to activate ionotropic glutamate receptors on hippocampal neurons. It is also supplemented by pictures, which are extremely useful for the comprehension of this thesis. The authors have no doubt done a good job in writing up this article. Not only has the information been provided with a systematic and methodical approach, it has been made sure that each conclusion that has been concurred has a factual experimental basis, which is mandatory and extremely impressive, especially as figurative data has been imparted. Though the material has been extrapolated and unnecessarily lengthened a few times due to repetition of certain clauses that could have been avoided, overall it provides all the essential information that a student would require. What has been most intriguing is the function of astrocytes as vasomodulators, ie, as intermediary regulators of blood flow and experimental basis showing that application of neurotransmitters like norepinephrine, acetylecholine can mobilize astrocytic calcium, suggesting extrinsic axon pathways can also act on astrocytes to regulate the calcium. The basis for bi-directional glutamate-mediated signalling between astrocytes and neurons is unclear and the concept of neuroligands is enlightening. The various experiments employed to support the notion that glutamate is the neurotransmitter mediating astrocyte-neuron signaling are satisfactory, however the fact that the researchers have gone one step further to explore the action of other

Computer security Term Paper Example | Topics and Well Written Essays - 1500 words
Computer security - Term Paper Example Once, one comes to terms with this astounding fact that then comes in the concept of computer security. Simply speaking the purpose of the computer security is to look to it that the data residing within the computers remains safe and sound. The arrangements for computer security within organizations look to it that no harm gets done to the computers owned by the organizations and the information saved in those computers remains inaccessible to the unwanted people and organizations (Gollmann, 1999, p. 9). Most of the computer security systems have been designed with the help of the logical technologies. The concept of computer security is mostly relevant in the situations where a computer or computers in an organization are connected to other computers and networks with the help of the accompanying networking technologies and services (Gollmann, 1999, p. 10). The primary and essential objective of the computer security is to protect the organizations from unwarranted data loss and th e resultant financial and intellectual losses. The Debilitating Consequences of Data Loss The data saved in the digital hardware and computer networks within corporate and financial organizations could be considered to be the very backbone of these institutions. Any loss to the organizational data in the form of a data theft or a virus threat or say a natural disaster does always have the potential to bring an organization to its knees. Most of the times it is almost impossible to recover the lost data and any recovery if possible is not devoid of a serious threat to the viability of the concerned organization (Vacca, 2009, p. 40). As already said, the businesses in the 21st century are totally digitized and do tend to depend on their hardware and computer networks for survival and sustenance (Vacca, 2009, p. 469). In this very fact lies the very vulnerability of these businesses, which if not safeguarded with the help of proper security, could give way to irretrievable losses and damages. The consequences of a data loss to an organization owing to a lack of computer sec urity or a breach of this security could be manifold. It is not exactly possible to financially quantify the losses owing to data loess, but it would not be wrong to say that such losses at an international scale do run into billions of dollars (Vacca, 2009, p. 136). Research has shown that many companies every year have to contend with data loss, which also includes some of the most reputed companies of the world (Vacca, 2009, p. 136). Many of such companies when struck with a data breach or data losses get immediately shut down and even those which manage to strive, a considerable number have to deal with dire consequences in the following years (Vacca, 2009). Realistically speaking it is not always possible to estimate the losses incurred by a company owing to data loss. In the age of brand considerations and intellectual property, if the impact to the perceptions and views of the customers and trading partners owing to data loss could be considered to be tangible assets, then th e looses to a company owing to loss of sensitive data and information is no doubt invaluable and debilitating. Hence, the biggest loss that an institution, corporation or organization could face owing to data loss
