Historical Report on Race free essay sample
A life that we thought was best for us and our kids to grow up in. We produced our own food, shelter and weapons and revived for ourselves in the most natural way possible. It wasnt always easy though, and others seen more value out of our land and resources than us. I was forced off my land and had to adapt to the new peoples way of life. That in which they called a white society; this society created many acts in my life time in order to weaken our society such as those of the Allotment Act and the Reorganization Act (Schaefer, p. 47, 2012). People of my cultural lived on reservations, we had learned to separate ourselves and adopt our own way of life and government. Native Americans ad created their own nation and it caused and has caused a lot of tension between us and the U. S. Culture. As a Native American, we were all about live the traditional way of life. There was value to our land and the resources that we used and the white people wanted and did take it from us.It seemed as if we were constantly at war with the white people so that we could protect what we thought was rightfully ours. They had created an act known as the Indian Removal Act, which was passed in 1830 (Schaefer, p. 150, 2012). This opened more land for settlement and allowed people to come in and take ever our reservations (Schaefer, p. 150, 2012). In 1946, Congress had created the Indian Claims Commission (Schaefer, p. 1 50, 2012). This was a good thing for us, or so we thought. It meant that finally our voice was going to be heard.There were three members apart of the commission, and they were given a five year deadline, but there kept getting extension after extension, until; in 1978 the whole thing was abolished (Schaefer p. 155, 2012). At times, it seemed as if maybe the government was trying to help us, that or they were trying to use us. In 1 952, the BIB began programs, so that they loud relocate young Native Americans to Urban areas and by 1962 they had created what was called the Employment Assistance program; also known as the EPA (Schaefer, p 1 57, 2012).Basically there primary goal was to relocate us by offering us better jobs opportunities that, that of the reservation could not offer. But this plan had soon backfired on them. By 1 965, one-fourth to one third of the people in the EPA had returned home to their reservations (Schaefer p. 157, 2012). Today, most of our land has been taken from us and no longer exist. Native Americans themselves are not being treated as badly as we were back then, but its the culture and our name that continues to be insulted. Schools have such a thing as mascots, and they create names for them.They use those such as the Braves or Redskins. Those names have a meaning to the Native American culture, it tends to bring up the past for us, and though there intentions may not be that of insulting us, some of us dont like it too much. It hasnt always been easy for us, and at times wanted to give up. But everything seems to turn out for the better. Ive learned that every culture ND person has their own Way of living and when someone sees a greater value of that persons living then they have to have it. Things dont always have to be that way; people can come up with their own greater value of living. Remember, you dont always have to have someone elses greater value to have a greater value of your own. Make an even better living for yourself than trying to take someone elses.

Theories and Principles Unit 4 Dtlls Essay Example
Theories and Principles Unit 4 Dtlls Essay In psychology and education, learning is commonly defined as a process that brings together cognitive, behaviour and Humanists elements. This assignment shows the concept of the relevant theories and principles of learning and communication; select and critically analysed of how I plan to deliver these strategies in my own teaching; and reflect on the impact that these insights have had on my own practice and professional development. What is the definition of theory? To me theory is something which is explained to you, a system of ideas intended to explain something, one based on general overview. A definition of principles, to me is to be opinionated on how I feel towards chosen topic. Geoff Petty (2009) states that, `every teacher and every learner has a theory about learning. ââ¬â¢ To able to conclude my own theories and principles on planning and enabling learning I need to learn what is accepted to others. Research I understand there are many different theories relating to teaching and learning. Those that I have looked at are Behaviourist, Cognitive and Humanists elements. These are not new concepts. Although that some of these theorists are descended their work is still use into practices. Behaviourism is primarily associated with Pavlov (classical conditioning) in Russia; and with Thorndike, Watson and particularly Skinner in the United States (operant conditioning). In educational surroundings, behaviourism implies the dominance of the teacher, as in behaviour modification programmes. It can, however, be applied to an understanding of unintended learning.

Frederic Skinnerââ¬â¢s work was influenced by Pavlovââ¬â¢s experiment and the ideas of John Watson, father of behaviourism. His interest in stimulus-response of how humans reacted to various situations became fascinating. Skinner developed teaching machines, so students could learn, uncovering answers for an immediate ââ¬Å"rewardâ⬠. Humanistic, humanism and humanist are terms in psychology relating to an approach which studies the whole person and the uniqueness of each individual by emphasizing the study of the person overall. This behaviour clarifies the ability of learners to respond to the lesson. John Holt, How Children Fail (1964) states that ââ¬Å"the school system could destroy the minds and emotions of young children. His blistering attack accused schools of inducing fear in pupils, and humiliating, ridiculing and devaluing themâ⬠This is a very generalised point of view due, to the fact that Holt is tarnishing all schools with the same reputation. However, it is important not to completely dismiss his views, as the point he makes about fear of failure is something we must be aware of in our teaching. In another humanistic approach which also fits within the humanistic spectrum is that proposed by Malcolm Knowles (1913-1977) his studies focus on adult education which was formed in 1946. Formal programs were for those sponsored by educational institutions, such as universities, high and trade schools in America. He implemented that adult education was pointed to the friendly and informal surroundings. This enhanced adult learners to take more responsibility for their destiny as they mature through the learning process. Cognitive learning theory is about how to learn rather than what to learn i. e. how to write a report, how to recall specific facts, how to use learning to solve problems or be creative. Cognitivism is ââ¬Å"the psychology of learning which emphasizes on how we think and gain knowledge. Theorists are intrigued and want to understand how problem solving changes throughout childhood, how cultural differences affect the way we view our own achievements, language development. Theories such as Jerome Bruner (1915) and Lev Vygostsky (1896) expressed the view that `expository teachingââ¬â¢ deprived learners of the chance to think for them, however Vygostsky approach `Zone of proximal developmentââ¬â¢ focused on the concept that what a learner could do today with they could do alone tomorrow. The behaviourist approach can encourage me to understand what motivates my learners and to challenge them on what goals they wish to achieve through their learning. These techniques can influence and can allow me to shape and enhance my learners into behaving in an acceptable way through Skinnerââ¬â¢s theory of `Positive or Negative Reinforcementââ¬â¢. As a research a bi product of this will develop my learner way of analysing. This encourages a comfortable learning environment for all learners. Negative reinforces are ones that increase the chance that a behaviour will occur when it is removed. Punishments are events that decrease the frequency of behaviour that it follows (Skinner, 2003) Take the learner in the classroom that ontinually talk s to his neighbour; it reinforces his behaviour to continue, but if the teacher punishes him by having him stand up in front of the whole class and apologies, he will be more likely to refrain on talking again. Skinner believes that behaviour could be altered by using positive and negative types of reinforcement. Remember negative reinforcement is not punishment. If I have not covered everything on t he original lesson plan, learning can however be measured making assessment and planning for next session easier. By constantly revisiting certain topics and using Question and Answers learners have an understanding on what they are learning and why. This would not be the case for all, based on behaviour modification there are also disadvantages to this approach. Repetitive learning may encourage some learners to remember information but it doesnââ¬â¢t necessary mean they have understood the concept. Some learners will not be confident to admit this and just produced the required answers without knowing how they got to the answers. How do we include rewards and why the reason for them? As a teacher I tried to implement these when suitable for all learners. If this is not done then the whole process will become confusing and motivation will be lost. This theory can tend to lead myself towards the `pedagogical approach to learningââ¬â¢. As covering that the Humanistic approach is relied for individuals to explore their own interest and curiosities this will assure them to grow into fully functioning, self-trusting, and independent people. All individuals are unique and have an inborn drive to achieve their maximum potential. This I can relate too with the learners that I teach, once they have discovered their own personality this will generally relate to their chosen career options this will give learners to have free will in the learning experience and can effect on the change of their knowledge. I use the Humanistic approach to learning within my classroom as practical is a massive contribute to my teaching. Carl Rogers, in freedom to learn (1969) states that self-directed learning delivers the considerable educational advantages of independent learning. Advantages which I find to this are that by meeting learners needs, each learner will feel valued and respected. This will help build up a level of trust between the learner and teacher resulting to excellent communication. When planning and delivering lessons, I include various activities to allow this to happen. At the end of each lesson I find that group discussions give the learners freedom to induce new ideas and to listen to their peers opinions. This gives them the tools to feel empowered and have control over how they learn. This sounds like a perfect andragogical approach but could have some disadvantages. We know that Brunerââ¬â¢s cognitivists approach to learning is basis on emphasizing active restructuring of knowledge through own experience of life. With this theory the learner draws on his/her own past experience and acknowledges new facts, relationships and truths. Students interact with the world by exploring; asking questions and interpretation what is relevant to the subject. I. e. when tackling new ideas the learner relies on the teacher to give them the correct answer, assuming the teacher is in their comfort zone. To allow learners to achieve this transformation is by working in groups which encourages them to socially interact with one another which will then lead to process of learning, As a result this method students may be more likely to remember the concept and knowledge discovered on their own. Another strategy often used in my classroom involves embedding questions, which allows the learners to find out the answers to the problem before setting their task. This may again relate to their personal experience. Often organising school trips (exhibition, real life theatre) can allow the learners to interact with real life situations. I allow for discussion/debates around specific questions relating to that topic that I have structured to initiate points that are relevant to their learning. These theories have made me think differently to my own practise in the way I plan my lessons, which methods of delivery I use as well as how I assess what types of learning has taken place. I teach in a secondary school environment, where the learners go thought a transition from KS3, KS4 KS5. The course is practical, but there are some elements of theoretical methods which gives learners the chance to demonstrate skills in a performance environment. I agree that planning for lesson is a strong area for me and my learners. As a result, I will always construct the delivery of my own teaching including the three learning domains. I found that the Bruner strategy had the most impact on my teaching from both a practical and professional point of view. This has enabled me to encourage my learnerââ¬â¢s involvement by utilising these methods. It has now become a natural part of my lessons, which involves incorporating QA as well as discussions to assess that learning has taken place in the Affective domain. My confidence has developed as a result, as well as my learnerââ¬â¢s needs and communication is now at an all time high in the classroom. These areas are now a massive part as to how I deliver a lesson, as well as ensuring that communication flows both ways. After conducting research into the theories of learning, I have realised there are some improvements that need be made. One of these involves giving my learners more freedom and responsibility with the answers, rather than prompting them. I believe this simple change can breed confidence and progress for both me and the learners. Bibliography Skinner, B. F (Reprint 2003). The Technology of Teaching. Cambridge, MA: B. F.

The comparison of Lukoil & BP Case Study Example | Topics and Well Written Essays - 2750 words
The comparison of Lukoil & BP - Case Study Example The company registered thelargest trading volumes among foreign companies tradedon the London Stock Exchange (IOB) in 2005 and at home, the Russian Trading System - also in 2005. Sales coverage includes the 59 regions Russia and 16 other countries -Azerbaijan, Belarus, Georgia, Moldova, Ukraine, Finland, Bulgaria, Hungary, Cyprus, Latvia, Lithuania, Poland, Serbia, Romania, Czech Republic, Estonia, and the USA. Distribution operational capacity stood at 199 tank farms and 5,405 gas stations by the end of the year 2004. This includes 779 Mobil gas stations throughout the USA (LUKOIL, 2006a). BP was formerly known as British Petroleum and is a British energy company with headquarters in London. After merging with the Amoco Corporation, the company was named "BP Amoco". After a single year of joint operations, the company drop the Amoco name and BP now stood for "Beyond Petroleum". The company is regarded as one of the oil, natural gas and petrol leaders in the world. In the 2006 Fortune Global 500 list of companies, BP was ranked 4th in the world for turnover with sales at $268 billion which was down from 2nd in 2005 and 1st among oil companies the. The 2006 Forbes Global 2000 ranked BP as the 8th largest company in the world with profits in 2005 amounting to $22.341 billion. The number of service stations stood at 28,500 with 15,900 based in the USA alone. Proven reserves amount to 18.3 billion barrels of oil and gas (57/43 percentage distribution). The company is active in 26 countries with production activities in 22 of them. (BP, 2006b) Methodology In this paper, we will be comparing which company between LUKOIL and BP is more investment equitable. BP, having been in the business since 1889 (Amoco), has established itself as the foremost leader in the global oil industry as we have seen in the company's profile. However, as we will be seeing later, LUKOIL has seen a tremendous growth in performance. The BP, being well established in the industry, has certain advantages over LUKOIL such as business management expertise honed by years in the industry and a larger market share and production capacities. But this edge may very well be overcome with the current performance of LUKOIL. To determine which of the two will be more equitable, we will be looking into the financial health of the company especially the equity returns. We will also be considering the economic trends and the political factors that affects the profitability of LUKOIL and BP as these are major determinants of the risk involved in investing in the company.. Special focus will be given to the developments in Russia, which have contributed to the tremendous growth of LUKOIL.

Managing across culture Essay Example | Topics and Well Written Essays - 2500 words
Managing across culture - Essay Example The aspect of culture can also be used towards supervising locally recruited employees. Samovar, Porter & McDaniel (2009) posit to the effect that understanding the mode of communication within a business culture is an asset for proper and peaceful interaction of business people and the locals. In order to excel in business, it is important to have the right cultural facts about the citizens living in a particular society. This helps business to design its strategies so that they are able to absorb the cultural shocks that may emerge in the course of their activities. Cultural shock is a concept which entails that ââ¬Å"any move from one country to another will create a certain amount of confusion, disorientation and emotional upheaval and this is called culture shock,â⬠(Robbins, 1993, p. 78). ... This reflective report will try to provide detailed information regarding hierarchy, gender roles, communication and relationship, greetings, and social interactions in US which can affect a business venture I intend to set in this country. A conclusion based on the findings of secondary research will be given at the end of the report. Business Culture of United States United States is the third largest country in the world and it is one of the best performing economies across the whole world. It borders with Canada, Mexico, pacific, Atlantic oceans, and Caribbean Sea and its population in the year 2007 was estimated to be 301,139,947 (Moran, Harris & Moran, 2010). There are many ethnic groups in the US and it is believed that the whites occupy the largest percentage of about 81.7% while other groups such as black occupy 12.9%, Amerindian and Alaska 1%, Asian 4.2%, and Hawaii and Pacific Islander 0.2% (Moran, Harris & Moran, 2010). Research has shown that United States has a wide ran ge of cultures hence most people who stay in America have their ancestral connections that belong to another culture. In most cases, their ancestral cultures are in Scotland, Germany and Ireland. A comprehensive analysis of cultural diversity has been done by Geert Hofstede who found that national culture has a major impact on employeesââ¬â¢ work related values and attitudes (Robbins, 1993). He found that managers and employees vary on five dimensions of national culture namely individualism versus collectivism, power distance, uncertainty avoidance, quantity versus quality of life as well as long term orientation. According to studies, rich countries like the US are very

Marginal and Absorption Costing for Financial Statements
Marginal and Absorption Costing for Financial Statements This paper aims at looking at how income statements are prepared using marginal and absorption costing. The absorption costing method charges all direct costs to the product costs as well as a share of indirect costs. The indirect costs are charged to products using a single overhead absorption rate which is calculated by dividing the total cost centre overhead to the total volume of budgeted production. (ACCA, 2006; Drury, 2006; Blocker et al., 2005). On the other hand under marginal costing, only variable costs are charged to cost units. Fixed costs are written off the profit and loss account as period costs. (Drury, 2006; Blocker et al., 2005). Sections a) and b) below show the marginal and absorption costing income statements respectively for H Ltd that manufactures and sells a single product during the years ending 2006 and 2007. It is assumed that the company uses the first-in-first-out (FIFO) method for valuing inventories. In addition it is assumed that the company employs a single overhead absorption rate each year based on budgeted units and actual units exactly equalled budgeted units for both years. Workings are shown the attached excel file. Marginal Costing Absorption costing. Reconciliation of net income under absorption and Marginal Costing. Under marginal costing inventory of finished goods as well as work in progress is valued at variable costs only. On the contrary, absorption costing values stocks of inventory of finished goods and work in progress at both variable costs and an absorbed amount for fixed production overheads. (ACCA, 2006; Lucy, 2002). In the case of H Ltd, under marginal costing, only variable costs are included in the ending inventory figure. This results in a profit figure of à £400,000. On the other hand absorption costing includes additional à £200,000 as fixed overhead in the ending inventory for 2006. As a result absorption operating profit is overstated by à £200,000 in 2006. In like manner, the absorption profit under absorption costing is overstated by à £140,000 due to an inclusion of à £140,000 of fixed overhead cost in the ending inventory figure for 2007. To reconcile the profit under absorption costing and marginal costing, we may either subtract the fixed overhead included in endin g inventory from the absorption cost operating profit to arrive at the marginal cost operating profit or add the fixed overhead costs in ending inventory to the marginal cost operating profit to arrive at the absorption cost operating profit. Stock Build-ups Stock build-ups may result from using absorption costing for performance measurement purposes because inventory is valued at both fixed and variable costs. Firstly, profit is overstated. In fact absorption costing enables income manipulation because when inventory increases fixed costs in the current year can be deferred to latter years and as such current net income is overstated which in effect results in financial statements that do not present fairly and as such affect usersââ¬â¢ decisions on the financial statements. Secondly, maintaining high levels of inventory may result in obsolescence and as such declines in future profitability resulting from the loss in value of the inventory. (Blocher et al., 2005; Storey, 2002). Advantages of Absorption Costing and Marginal Costing According to ACCA (2006) the following arguments have been advanced for using absorption costing: It is necessary to include fixed overhead in stock values for financial statements. This is because routine cost accounting using absorption costing produces stock values which include a share of fixed overhead. Based on this argument, financial statements prepared using absorption costing present a true and faithful representation of the actual results of operation of the company. For a small jobbing business, overhead allotment is the only practicable way of obtaining job costs for estimating and profit analysis. Analysis of under/over-absorbed overhead is useful to identify inefficient utilisation of production resources. ACCA (2006) also identifies a number of arguments in favour of marginal costing. Preparation of routine cost accounting statements using marginal costing is considered more informative to management for the following reasons: Contribution per unit represents a direct measure of how profit and volume relate. Profit per unit is a misleading figure. Build-up or run-down of stocks of finished goods will distort comparison of operating profit statements. In the case of closing inventory, the inventory is valued only at the variable cost per unit. This makes the profit under a situation where there is closing inventory to be the same as the case when there is no closing inventory thereby enabling the comparison of operating profit statements over time. Unlike under absorption costing, marginal costing avoids the arbitrary apportionment of fixed costs, which in turn result in misleading product cost comparisons. Bibliography ACCA (2006).

Assembly language vs. Mechanical language Essay
Assembly language can execute the same commands as machine language; however, the commands have names instead of numbers. Assembly language, unlike machine language, is a symbolic representation of operation codes, symbolic memory addresses and pseudo codes, which makes the virtual environment user friendly. Machine language, on the other hand, is represented as binary bits consisting of a string of 0s and 1s, which makes the virtual world challenging since the lingo is only comprehended primarily by computers. Therefore, assembly language is considered more user friendly than machine language. Assembly language enables programmers to relate op codes using symbolic names in place of numbers to perform an instruction or input a piece of data. Programmers can inscribe op codes using purposeful words like JUMP, CLEAR, and ADD as an alternative to cryptic binary codes consisting of series of 0s and 1s. An example of assembly language, machine language and its meaning are listed in the book called, ââ¬Å"Invitation to Computer Scienceâ⬠(Schneider & Gersting, 2013, pp. 285, fig. 6.5). In figure 6.5, assembly language is clearly easier to comprehend than machine language, which makes assembly language user friendly. In addition, assembly language allows programmers to utilize symbolic addresses to replace numeric memory addresses in binary bits to execute a command or input data. Computer specialist can link symbolic labels to an instruction or piece of data in the program. In other words, the symbolic label turns into a permanent tag for the instruction or piece of data disregarding where it populates in the program or where it relocates in the memory. However, machine language is more complicated. To perform an instruction or input data in the memory in a specific location, the computer specialist must specify the direct address. For example, ââ¬Å"In machine language, to jump to the instruction stored in memory location 18, you must specify directly to address 18 (write JUMP 18 in binary code). The programming is complicated if a new instruction or data is introduced anywhere within the 18 lines of the program, the jump location 18 shifted to 19. According to Schneider and Gersting, ââ¬Å"This makes modifying programs very difficult, and even small changes become big effortsâ⬠(2013, pp. 285). Assembly language use symbolic address is proven to be more user friendly than a numeric address for programmers. Moreover, pseudo code allows the programmer to use a special type of assembly language to be converted into op code referred to as pseudo op. Unlike other operation codes, a pseudo ââ¬âop does not develop a machine language for instructions or data. In order to execute such task, pseudo-op implores the service of the assembler. One of the many services provided by the assembler is the ability to generate instructions or data into the suitable binary likeness for the system. A brief summary of the conversion is documented in the publication ââ¬Å"Invitation to Computer Scienceâ⬠(Schneider & Gersting, 2013, pp. 287). The summary breaks down how the pseudo-op commands the assembler to generate a binary representation for the integer, and so on. If a programmer had to manually construct the conversion, this would prove to be a very cumbersome task. Therefore the application of assembly language pseudo-op makes the task more favorable for the user. Consequently, assembly language symbolic representation of op codes, addresses, and pseudo codes all makes the virtual environmental experience for users more appealing than that of machine language. Assembly language is developed with the human factor in mind and with that, the experience for the programmer is uncomplicated. Advancement in the virtual world deemed assembly language more appropriate named low-level programming language. Where machine language in the virtual world was once considered primitive, assembly language to, now resides in the same era. In the land of programming, the assembly language created for a specific task or data input must be converted into machine language. The conversion is executed by an assembler. Therefore, low-level programming language, in the same manner, has to convert into machine language the same. More specifically, ââ¬Å"Each symbolic assembly language instruction is translated into exactly one binary machine language instructionâ⬠(Schneider & Gersting, 2013, pp. 282). The translation into binary machine language means that instructions or data is represented by a series of 0s and 1s in order for the computer to execute the instruction or store the data information given. Schneider and Gersting said it best when they stated, ââ¬Å"â⬠¦it is the language of the hardware itselfâ⬠(2013, pp. 282). Since programmers are not hardware the process could prove to very cumbersome for users. The silver lining in this storm is the creation of high-level programming language. Unlike low-level programming language, high-level programming language is more maneuverable by the programmer. High-level programming language is created to use both natural language and mathematical notation. In other words, Schneider and Gersting states, ââ¬Å"A single high-level language instruction is typically translated into many machine language instructions, and the virtual environment created by a high-level language is much more powerful than the one produced by an assembly languageâ⬠(2013, pp. 282). In short, high-level programming language differs from low-level programming language in that the translation into many machine languages versus translation into one machine language is more powerful. Moreover, high-level programming language is user friendly rather than low-level programming language which is computer friendly. Since the general idea is making the virtual world friendlier for its users, if Internet did not exist, I would not be so friendly. I access the internet on a daily basis for a variety of tasks like; paying bills, scheduling and canceling appointments, recipes, purchases, banking, and the list could go on and on. However, the most important area of internet use is paying bills. Prior to the internet, paying bill required physically visiting the establishment where the bill is to be paid, purchasing a money order in some cases, writing a check or even more archaic, paying with cash. Somehow, a bill or two slipped through the cracks. Now that the primitive days are over and technology has advanced the human nation, auto pay makes life much easier. The merchants that are due payment for services rendered receive payment automatically and all that is required, is manually setting the date, amount and merchant to be paid. Auto pay is convenient, one less tree is destroyed and gas is saved for another day. Simple as my reasons may be, it works for me. Advance in virtual technology make life easier for internet user, however, piracy can present itself as a problem if certain protocols are not put in place. When communicating with others over the internet, there are many ways to safeguard your computer, here are five protocols used as protection while communicating over the internet, authentication, authorization, encryption, system administrator, and firewalls. A combination of all these protocol could safeguard users while communicating over the internet. Authentication is a way of verify the individual right to access a computer. The individual accessing the computer usually has a unique username and password that allows the computer to recognize the individual to allow access to the system. For example, most employers allow their employees access to computers on the job for various duties. However, some user have restrictions where as others do not. In, ââ¬Å"Invitation to Computer scienceâ⬠, a passage on authentication reads, ââ¬Å"When a user attempts to log on to the machine, the operating system reads the user ID and checks that the password matches the password for that user in the password fileâ⬠(Schneider & Gersting, 2013, pp. 391). Piracy can still occur if this is the only protocol used. However, if authentication is partnered with encryption, communication may not be compromised over the internet. Encryption allows users to create a message in plain text but before it is send to its destination the message is encrypted also known as ciphertext. When the message is obtained by the receiver the content is decoded so it is able to be read. However, if the message is hijacked by the incorrect receiver, the plain text remains encrypted. Encryption according to Schneider & Gersting, ââ¬Å"is the process of using an algorithm to convert information into a representation that cannot be understood or utilized by anyone without the proper decryption algorithm;â⬠¦Ã¢â¬ (2013, pp. 401). Moving along in safe communication over the internet is authorization. Authorization dictates what an authenticated user has permission to do. Contingent on whom the authorized individual may be, they possess the ability to read, write, execute or delete files. The text, ââ¬Å"Invitation to Computer Scienceâ⬠states, ââ¬Å"The system administrator or superuser has access to everything, and is the person who sets up the authorization privileges for all other usersâ⬠(Schneider & Gersting, 2013, pp. 395). A more tangible explanation is, I am the system administrator for my personal laptop and I delegate authorization to other users. Next in safety is firewall software. Firewall software blocks access points to a usersââ¬â¢ computer. It inhibits communication to or from sites you the user do not allow. In addition to safety while communicating over the internet, safeguarding your computer against viruses is vital. One measure a user can utilize to safeguard their computer against viruses is antivirus software. There is much antivirus software available on the market but the main two that comes to mind is Norton and McAfee antivirus software. Both seem to be popular amongst consumers of today. Antivirus software recognizes viruses, worms and Trojan horses by unique signature these programs transmit. The software wipes out the tainted program being transmitted which safeguards your computer from any threats. In the last 12 months, the following three computer viruses have had a significant impact on business are Shamoon which attacked Saudi Aramco oil company computer, St. Barnabas Healthcare System e-mails were infiltrated by Melissa and a Chinese hacker infiltrated the Times computer system through malware which granted them access to any computer on the Times network. The morning of August 15, 2012 a virus was unleashed to execute the destruction of a company called Aramcoââ¬â¢s, corporate PCs documents, spreadsheets, e-mails, files putting in place of all the items demolished, an image of a burning American flag. The person responsible for such destruction is unknown but the article states, ââ¬Å"â⬠¦a person with privileged access to the Saudi state-owned oil companyââ¬â¢s computersâ⬠¦Ã¢â¬ is the villain (Perlroth 2012). The name of the virus that collapsed Aramcoââ¬â¢s computers is called Shamoon. The virus compelled the company to terminate the companyââ¬â¢s internal network in efforts to hinder the virus from spreading like wildfire. In another article, St. Barnabas Health Care System e-mails were sabotaged by the horrendous e-mail virus Melissa. The virus surfer the information highway and infected E-mail systems worldwide, hindering networks and hard drives and to add insult to injury destroyed data. In efforts to save the St. Barnabas Health Care System immediate shut down of the system and networks was in order to rid the organization of the problem. In the same manner, Chinese hackers installed malware to infiltrate Times computer system to obtain passwords for personnel employed by Times. The Chinese hacker had a four month running spree of consistently attacking Times systems. The article states, ââ¬Å"The timing of the attacks coincided with the reporting for a Times investigation, published online on Oct. 25, that found that the relatives of Wen Jiabao, Chinaââ¬â¢s prime minister, had accumulated a fortune worth several billion dollars through business dealingsâ⬠(Perlroth 2013). In efforts to intercept the Chinese hackers attacks, Times employed security guru to detect and block the attacks. Perlroth reports, ââ¬Å"Computer security experts found no evidence that sensitive e-mails or files from the reporting of our articles about the Wen family were accessed, downloaded or copied,â⬠said Jill Abramson, executive editor of The Timesâ⬠(2013) References Larson, A.
