Political Party and Internet Essay

HARATAL In modern strife torn state hartal has become a common affair. It is observed at the call of a political party or parties to press their demand to protest against the corruption, misuse of power and the evil deeds of the ruling party. Sometimes students and people of a locality call hartal to express their demands. On a hartal day normal course of life is stopped. All means of transport and vehicles do not move on the roads. People are to take a lot of troubles to attend their offices. They go on foot as vehicles are not available. As a result the attendance is very negligible in the offices, factories, industries and shops. The economy of the country suffers a heavy loss. Mills, factories, industries and shops stop their work. All the business centers, markets and shop remain closed. The supporters in favor of hartal bring their procession. Often clashes occur between the police and the picketers. Sometimes clashes take place between the supporters of the opposition and the ruling p olitical parties which result in some deaths. On a hartal day the sufferings of the people know no bound LOAD SHEDDING Load-shedding is the suspension of electricity supply on certain lines when demand is greater than the generation. It occurs when the generation of power is less than the demand. Besides, unplanned distribution and illegal connection of electricity are also responsible for it. It creates various serious problems. The students are affected by it if it occurs at night. They sit idly in the dark closing their books. They suffer terribly owing to load-shedding on the night before their examination. Mills, factories, industries, all academic and socio-economic institution seriously suffer due to it. It seems that everything comes to a standstill and so life becomes rally painful. In a country like ours it is very difficult to solve the problem of load-shedding. Yet we can go a long way by establishing new power plants, ensuring planned distribution, reducing system loss and checking illegal connections. If these are ensured, we may expect to get rid of the curse of load-shedding. Governme nt should also take effective steps in this regard. Computer The computer is one of the most brilliant gifts of science. This device was originally developed by Charles Babbage. Most countries have developed fast due to computerization. Writing a program is essential for a computer. Speed, accuracy, reliability, and integrity are the main characteristics of a computer. Many of the routine activities today at home and in business are done by computers. The computer has proved a friend and servant of science, technology and industry. Most offices, shops, factories and industries use computers. The Internet is a storehouse of information. The computer is boon to all. Telecommunication and satellite imageries are computer based. Computer has made the world a global village today. The Internet The information system of the world has become globalized with the magical touch of internet. Like a spider-web the Internet has spread its interconnected link with tens, hundreds or even thousands of computers. And it has enabled them to share information and communication with one another widely, effectively and inexpensively.The Internet has made it possible for people all over the world to bring the information and communication system within their palm. The Internet has brought new opportunities to government, education and business. Governments use the Internet for internal communication, distribution of information and automated tax processing. Bangladesh as a developing country does not have access to the Internet in all spheres. Still internet here has some access to the business world and the banking system. Educational institutions also use the Internet to some extent. Internet here also allows a great variety in digital entertainment. People can enjoy music, movie, gaming, chatting with friends, sharing views and ideas about world affairs just by pressing few keys. We hope that we will get full-fledged access to the Internet, an international computer network, to make our Bangladesh a developed and prosperous country. TRAFFIC JAM Traffic jam is one of the most irritating problems in bangladesh. It has taken a very serious shape in city areas.This problem is the result of rapid growth of population and the increasing number of vehicle. In proportion to our population, roads have not increased. Moreover, cities are full of rickshaw and rickshaw pulles do not follow the traffic rules never maintain a queue while waiting to proceed. Untimely loading, unloading of goods of trucks, unauthorised markets by the road side, unwise parking to vehicles, public meeting, processions etc. Generally cause traffic jam. Narrow roads in another cause of traffic jam. Most often traffic jam occurs at office time and also at the time when the officer break. Sometimes traffic jam is so heavy that it blocks half a kilometre. It kills our valuable time and cause great suffering to the dying patients being carried in the ambulance. However, this problem can be solved by adopting some measures. Well planned spacious road should be constructed. one way movement of vehicles should be introduced.Traffic rules should be imposed strictly so that the drivers are bound to obey them. The number of traffic police should be increased.

Economic Developments Essay

The current system of the world economy has emerged as a result of the historical trends and economic developments that occurred in the past particularly during the periods of World War I, World War II and the Cold War. To a significant extent, the current world order and the capitalist and industrial prosperity that is being experienced today are products of historical economic developments. This paper examines the economic developments from 1913 to the present including the history of self-determination in the world economy in relation to the current world economy. Consequently, the role of the United States from being an isolationist to an economic hegemon is analyzed. Economic Developments from 1913-Present The period from Post World War I up to the present can be considered to be a see-saw of economic prosperity and economic crises for most countries. For countries like the United States the war had brought about economic development but it also caused the economic downturn for countries like France and Germany. Capitalism began to ensue and trading had been more active. Hence, the period from 1920-1929 signaled the massive economic progress in the world economy- industries were established and the percentage of industries to agriculture rose. After this massive growth however, the unemployment rate and poverty that ensued from the period of 1929-1941 had led to the Great Depression- interest rates were high, hyperinflation ensued and the rise in debt had led to stock market collapse. The world economy had experienced a systemic recession leading the collapse of markets worldwide. In this era, the GDP and GNP of nations dropped and poverty ensued as world trade had been inactive. After the Great Depression, the World War II had created another economic era- post World War II had been considered to be a golden era for capitalism worldwide. This is because of the rapid rise in industries, the technological advancement, the prospering and stabilization of world trade, domestic and international institutions had been established in order to facilitate the world economy. Consequently, the World Trade Organization, the World Bank and the IMF were established in order to aid countries needing economic lift in order to aid in their industrialization. Backed by capitalism and foreign direct investments, this era can be considered the time when the world economy had boomed. However, after this period the time between 1970s-1980s, inflation and interest rates grew up and the fixed interest rates were deregulated in order to let the world economy repair itself. This era had however, contributed in terms of the massive plan to reorganize domestic economies through fiscal policies. The post Cold War on the other hand, marked the era when the US became the sole hegemon after the downfall of Russia. Before the Cold War, democratic countries can only trade with democratic countries and communist countries are only limited to trade with communist countries- the downfall of Russia opened the doors for all countries to be participants in the world economy. Hence, during the period of 1990 and up to the present times, despite some economic fluctuations, the world economy can be considered as stable and progressive. While there are ups and downs, the stability of the world economy in the present times cannot easily succumb to another depression. Self-Determination and in the World Economy Self-determination started after the World War I as a result of the Treaty of Versailles- it declared that the sovereignty of the states should take charge of the whole population. World War I led to the breakup of the Hapsburg and Ottoman empires and the birth of a new generation of nation-states. At Versailles, U. S. President Woodrow Wilson’s famous Fourteen Points–the fifth of which declared that sovereignty should take full account of the interests of the populations concerned–formed the basis for the treaty ending the war. After World Wars One and Two, self-determination inspired the demolition of empires and the formation of new sovereign states; the concept being thus extended in the 1940s and 1950s to apply in the context of the decolonisation process. In the 1960s and 1970s, the principle of self-determination clashes with the principle of territorial integrity and global leaders are increasingly seeing this angle to the problem. In fact, even the UN resolution 1514 adopted in 1960 which elevated the status of self-determination, had also emphasized territorial integrity: any attempt aimed at the partial or total disruption of national unity and territorial integrity of a country is incompatible with the Purposes and Principles of the Charter of the United Nations. The international system was caught up in the contradiction and had exhibited some degree of ambivalence at least after the post-war decolonisation. It can be observed that the further extension of the principle today, as it inspires the surge of ethnic politics and threatens the break-up of the established post-colonial order. The United States as the World’s Political and Economic Hegemon The United States before World War I cannot be considered to be an economic or a political superpower, it derived its wealth from World War I from selling ammunitions and exploiting the economic opportunities caused by the war. However, in World War II, the US emerged as one of the more powerful countries not only in terms of technology but also politically and economically after surviving the Great Depression. The Post World War II established the United States from a country in the middle to that of a global hegemon. For one, post World War I saw the US to be involved in trade, the importation and exportation of goods as well as in searching for new territories to expand its power and industries. Post World War II saw the United States cementing its economic and political hegemony- it had established itself as one of the most prosperous and progressive countries not only through its GDP and GNP but also in terms of its ability to impose upon other countries. The United States during this time served as one of the economic powers together with countries in Europe, Japan and the USSR. Upon entering the Cold War, the world became a division of the US and the USSR or democracy versus communism. During this era, the United States served as an international role model for democracies as well as the patron of democratic countries. The fall of the USSR catapulted the US to its role today as a global hegemon- except for North Korea, there had been no real threat to the supremacy of democracy and hence, the United States. During this time until the present times, the United States had been a major player in sanctioning countries that do not abide by international laws and regulations as well as being a forerunner in providing foreign aids as well as regulating trade activities. To be a partner with the US would be tantamount to economic growth. The power held by the US both politically and economically can be considered to spawn countries even in Asia and Third World countries. Needless to say, the United States can be considered to be the most important international player today.

Indias Cast System Essay Example | Topics and Well Written Essays - 2250 words

Indias Cast System - Essay Example It is linked to a concept called the four varnas, which will be covered in more detail below. The caste system comes about from an innate (something that a being is born with) spiritual place in the universe based upon these four varnas. The purpose of this paper is to investigate and evaluate the caste system in India and it’s relationships to Hinduism to provide a general overview of this important aspect of Indian life. The paper will also explore how important this system is for many Indians, and the changes that are being made to the system in response to global political change. Overview of the Caste System To fully understand the caste system of India, the specific consideration of different spiritual aspects is needed. Perhaps the most important part of the caste system is based around the central concept of the four varnas, which are large categories. The first of these (and the most highly regarded) is the Brahmin class. The usual translation for this caste is schola rly, representing the important role that this caste plays in religious and philosophical occupations within India (Fuller, 1979). The next most highly regarded caste is the Kshatriya, representing what could be considered a military elite or warrior class. The purpose of this caste in Hindu society is to protect society (Fuller, 1979). The third most important class according to the varnas is the Vaishya class. This is the pastoral or farming class, with many of the occupations of its members revolving around livestock and crop farming. This caste may also take up trade careers (Chandra, 2005). Finally, Shudra individuals are seen as part of the servant class. People born into this caste may typically expect to have jobs serving the members of the other three castes (Chandra, 2005). There is also a final group which may not be seen as part of the traditional caste system, for individuals who are not members of any other group. These people are known as the untouchables and can occu py some of the least favourable positions in society and can be ignored by members of any caste (Pruthi, 2004). There are also further divisions within each caste which are known as jatis (Singh, 2005). These can vary between Indian regions, but family members tend to remain within one jati (which dictates occupation). It is also traditional for jati members to marry within a group and carry on an occupation lineage, as with the much broader caste system described above (Singh, 2005). Each jati will fit with other ‘tribes’ into the more general caste system outlined above. These groups tend to be much smaller but still very close-knit in nature, which has led some people to call the jati the ‘building blocks’ of Indian society (Pruthi, 2004). It can be fairly difficult to move between jatis, as with castes, because intermarriage and communication between the groups is not generally encouraged (Pruthi, 2004). It may also be difficult for a member of one jati to learn the trade of another, again prohibiting movement between the groups (Pruthi, 2004). It is possible for a jati as a whole to improve social status by avoiding untouchables and unpleasant work and taking on more priestly ways (such as following the Hindu practices of vegetarianism, for example). History of the Caste System There is some debate about the origination of the caste system. As it has such close ties to Hinduism, it makes sense to evaluate the

What is your assessment of the progressives What contradictions do you see in the progressive movement. Had you lived between 1900 and 1920, would you have s - Essay Example These changes have to be done to civilize the cities without attracting America’s economy. This was the main aim of progressive movement. Another class of the society that was affected by the progressive movement was the working class. The working class women and the middle were brought together under one organization to solve social problems in legislative way. The progressive movement was started from the local government and then moved to the upper level government. The work efficiency was also boosted up during this era. A young expert named Fredrick W Taylor introduced new ideas of efficiency at working place which improved the productivity by speeding up the labor activity. In this progressive era, a young man with great political experience became the president of United States named Theodore Roosevelt. At the age of forty he became the youngest president of United States. The main cause that made him popular was his policies that reflected his personality as an activist and moralist. His main concern was railroad regulation which ended up with a compromise between the two positions. His greatest achievement was to conserve America’s natural resource. He won a noble peace prize for negotiating an end to Russo-Japanese war and preserving open door policy in China. Woodrow Wilson was the governor of New Jersey and became the president of United States in 1912. He started the Federal Reserve Act in 1913. This act provided the control of government over banking. He also introduced Federal Trade Commission Act that regulated the trade by taking commission from these trade corporations. He appointed commissioner to

ICELAND'S FINANCIAL CRISIS Case Study Example | Topics and Well Written Essays - 2000 words

ICELAND'S FINANCIAL CRISIS - Case Study Example During this time period, home values began to fall dramatically and sub-prime rates eventually readjusted so that individuals owed up to double their original mortgage value on homes that were no longer even worth their original market value. A vast variety of the sub-prime mortgages offered to individuals who actually did not maintain quality resources to sustain an adjustable home loan interest rate were suddenly forced into foreclosure, which left lending institutions with a significant inventory of now bank-owned homes worth less than their mortgage values at the time of signing. As the housing bubble burst and grew more fiscally unsound, global investors found that the many derivatives (swaps) associated with home mortgages were no longer viable and lucrative opportunities for investment (Simkovic, 2011). Many investors from the European Union and the United States began looking for better investment opportunities, leaving financial institutions offering these derivatives with c onsiderably less quarterly and annual revenues stemming from mortgage-backed swaps and securities. Because mortgage-related derivatives were, for many years, adequate and lucrative profit opportunities for financial institutions, many offering these securities backed by mortgage guarantees had not diversified their revenue-earning capacities. As such, investment trading partners in the United States witnessed capital depletion rapidly where many institutions required significant fiscal bailouts to keep the entity afloat. Further complicating this situation was what is referred to as a bank run, where nearly five billion dollars in investment resources were withdrawn domestically and internationally in a 48 hour period by concerned and speculating investment firms and independent investors (Altman, 2009). Low-valued credit default swaps, a variety of mortgage related derivatives, and banking facility capital depletion soon hit Iceland and many other European countries. Iceland, after banking privatization had been established, was very dependent on making investments in international capital markets (Olsen, 2010). However, this instability and credit downgrading that occurred during the sub-prime crisis in the U.S. had destabilized multiple investment opportunities associated with mortgage-backed securities and derivatives. Thus, a once lucrative revenue source for Icelandic banks and other financial institutions no longer provided adequate capital infusion for the now-private banking facilities in the country. Since there had not been enough portfolio diversification in Iceland to spark domestic investment opportunity to offset dependencies on international investment losses, the exchange rate of the Icelandic currency value was affected and derivatives relationships with foreign banking partners were largely nullified. As the IMF and the U.S. Central Bank began changing monetary policy and increasing regulation to correct the sub-prime crisis, it inflated the U.S. dollar which only served to further weaken the value of the Iceland currency on the international exchange markets. How could the Iceland Crisis have been Avoided? Firstly, Iceland should have recognized that the U.S. would not necessarily have explosive gains on mortgage-related securities and derivatives that would endure indefinitely. The U.S. had a long history of a volatile housing market which should have provided adequate

Managing high performance - Essay Example A second topic that should be discussed at the meeting is teamwork. A lack of teamwork is a symptom that is currently being displayed by the workers. The firm has to modify the work structure of the workers in order to design team assignments. The employees will learn to cooperate and work with each other better in team settings because they will be force to depend on the efforts of their teammates. â€Å"Teamwork is the ability to work together toward a common vision† (Carnegie). A third topic that is going to be discussed at the meeting is communication. In order for the current issues to be resolved the lines of communication between the workers and the managerial staff must be opened at all times. The communication process in the workplace has been enhanced by the use of technology. A technique that can help bring solidarity among the workers is to have weekly face to face meetings between the entire staff. Good communication is needed in business to achieve success (Mindt ools,

An analysis of google ( or apple , amazone) & cloud computing Research Paper

An analysis of google ( or apple , amazone) & cloud computing technology - Research Paper Example Cloud Computing with the virtual setting of softwares and hardwares, provides a effective IT network or Information system (IS) to the business firms, thereby even making their own network slightly redundant. Because of the growing potential, many more firms including Amazon are jumping into this field by setting up their own Cloud Computing environment and then commercially renting it to other business firms and clients. So, this paper will focus on the IS of Cloud Computing, discussing how it impacts Amazon’s, and how it has various applications, although there are some challenges while implementing and running it. The world of today is being ‘run’ mainly with the aid of technology, as it having applications in various facets of human life, starting from day to day activities to key applications in organizational or business environment. Technologies have evolved in various sectors, particularly Information Technology (IT) or Information Systems (IS) have evolved optimally aiding existing business firms in running, expanding, improving and even transforming their operations. Sizable numbers of business firms in various sectors are integrating IT in every aspect of their operations. From carrying out simple operations like opening a door or even authorized entry door to aiding in the accomplishment of complex processes, IT or IS are becoming an all-pervading entity in many of the business firms. The key fact is that emerging technologies or IS has many capabilities to optimally aid the business firms in improving their data storing, sharing as well as communication, which can aid t hem in carrying out all their organizational processes effective, providing them higher productivity and profits. Among the many emerging ISs, the technological or virtual concept of Cloud Computing can provide optimum benefits to the business firms who are using that concept, or if aptly said, are part of the â€Å"Cloud†. At the same time, this Cloud Computing is also positively

Answer the following question after reading Heart of Darkness Why does Essay

Answer the following question after reading Heart of Darkness Why does Marlowe lie to Kuitz's fiancee at the end of the Heart of Darkness - Essay Example The character Mr. Marlow, or to say the narrator, in the beginning of the story is projected as a protector of truth who tells a lie in its ending. Why Marlow decided not to tell Kurtz's fiance about her betrothed's final degradation require much in-depth knowledge about human psychology. The readers may be sympathetic towards Mr. Marlow as he was to rescue a resourceful person, Mr. Kurtz, who was ill in the dark forest of African Congo, but failed in his mission. At the same time arguments will arise about Marlow's hypocritical behavior when confronting Kurtz's fianc. Although, there may exist contradicting views about Marlow's behavior, it will be interesting to analyze the compulsions before him and interpret human nature in the outlook of Conrad. All the fictions are imaginary creations of literary artists, and writers have power to create disbelief and hold the reader into a satisfactory understanding of the plot. Though Heart of Darkness is termed as a travelogue, the element of imagination and literary creativity is also present in it. A good fiction offers the reader an exposure to good and bad characters that may have resemblance of people they know or come across in their own lives. Fiction makes sense when a writer tells a good truthful lie, and it successfully reproduces an event perfectly, which has never occurred to the reader. Once a writer is committed to tell the whole true lie and nothing but a completely true lie through their characters they can shape words to animate and convert into figures of people. For a successful writer readers are puppets in his hands and easily manipulated with their ability and creativity of white lies. Conrad has been successful in creating such elements in Heart of Darkness and it emerges a short but thrilling experience to the reader. The "Heart of Darkness," is considered as a travelogue and true life experience of Conrad, who was himself a navigator for many years. The readers are exposed to tricky situations and are carried away to illuminating mythological situations and dark inhuman activities with the skillful writing of Conrad. The story begins depicting Kurtz as an upstanding European who has been transformed by his time in the jungle-away from his home away from familiar people and food, and away from any community moral support that might have helped prevent him from becoming such a tyrant. Marlow is assigned to rescue this resourceful and knowledgeable person from the clutches of dark Africa. The factors compelling Marlow to decide not to tell Kurtz's fiance about her betrothed's final degradation requires much in-depth knowledge about human psychology. Marlow project himself as a protector of truth and hated world of lies. Marlow makes his feelings about lying explicitly through his words "You know I hate, detest, and can't bear a lie, not because I am straighter than the rest of us, but simply because it appalls me. There is a taint of death, a flavor of morality in lies, -- which is exactly what I have and detest in the world-what I want to forget. It makes me miserable and sick" (p.49-50). These words show that Marlow does not approve telling lies and it makes him miserable. His harsh words "not because I am s

Explain the doctrine of precedent Assignment Example | Topics and Well Written Essays - 1000 words

Explain the doctrine of precedent - Assignment Example Vertical application of the doctrine of precedent involves inferior courts applying decisions from superior courts in their rulings. Horizontal judicial precedent occurs when a court considers judgments of earlier judges or judges from other courts at the same level of the judicial structure. Superior courts can overturn decisions from other lower courts (Gerhardt, 2008). There are two main types of judicial precedents namely binding precedents, persuasive precedents. Binding precedents are mandatory judicial precedents that lower courts must abide by when making their rulings. Lower courts have to honor these precedents and apply them in their rulings. This mandatory authority usually comes from higher courts such as the Supreme Court (Gerhardt, 2008). Persuasive precedents are those that a judge can rely upon for guidance when making a ruling but need not necessarily apply them. These include decisions by lower courts or other courts in the same level of the judicial structure, obiter dicta statements of higher courts, and courts in other jurisdictions. This policy is very important for promoting justice, which is the main concern of the judiciary. I agree wholly with the relevance and importance of the doctrine of precedent because it plays a very important role in the judicial system of any common law jurisdiction by ensuring predictability of the legal system, maintaining stability, and promoting rational application of the law. Judicial precedent ensures stability of the legal system by maintaining the status quo of the legal system. The fact that Judges are required to uphold earlier decisions in their judgments makes it difficult for the legal system to be overturned or changes from time to time by unprofessional judges. This stability gives the law certain credibility and maintains public trust in the judicial system (Gerhardt, 2008). Without this doctrine, it will be difficult to control the legislative power of courts and authority of

APN concept paper Essay Example for Free

APN concept paper Essay What is advanced practice nursing? An advanced practice nurse is one who has successfully completed a post-graduate nursing program. Advanced practice nurses receive intensive classroom as well as clinical education. They are supplied with the tools to gain advanced knowledge and skills, and increased scope of practice in nursing. Advanced practice nursing describes a level of nursing practice that uses comprehensive and strong skills. Advanced experience and knowledge are utilized to assess, plan, implement, diagnose and evaluate patients’ care. Nurses who practice at this level have received post-graduate education and may choose to work with either a specialist or generalist concentration. However, advanced practice nursing is based on the elevated level of knowledge, skill and experience that is employed within the nurse-patient relationship in order to achieve the best possible outcomes. This can be achieved by utilizing critical analysis, problem solving and evidence-based decision making. Why is advanced practice important in nursing? Because of the intensive post-graduate education requirements, advanced practice nurses learn to effectively integrate theory, practice and their own experiences. They also develop the ability to independently make responsible decisions and to apply appropriate interventions. The advanced education requirements are designed in such a way that advanced practice nurses learn to formulate multiple approaches when making decisions, managing patients’ care, or collaborating with patients to achieve best outcomes. This is important as healthcare continues to evolve. Patients can feel assured of receiving appropriate and excellent care by an advanced practice nurse who collaborates with physicians. There have been studies conducted to assess the outcomes of patients cared for by advanced practice nurses and compared to those cared for exclusively by physicians. The results showed that patients of those advanced practice nurses working along with the physicians had equal or better outcomes than those who had been treated solely by physicians. Is all advanced practice the same? No, an advanced practice nursing student can choose from one of four areas of specialization: Nurse Anesthetist, Nurse Midwife, Clinical Nurse Specialist, or Nurse Practitioner. Each of these nurse specialties, particularly Nurse Practitioners, can choose to specialize in a particular field or focus on a specific patient population in which to provide care. Each specialty has a distinctive background and functions in a different capacity. However, they are all referred to as Advanced Practice Nurses.

Major Trends Which Affect Microprocessor Information Technology Essay

Major Trends Which Affect Microprocessor Information Technology Essay In the first section I selected the question about Memory Management Unit of Linux operation system. In this section I described the strategies and mechanism used by Memory Management, problems faced by these techniques and solutions to overcome it. In the section number two I chose the question about microprocessor. This question discussed how microprocessors work, major trends affecting to their performance, differences between microprocessors design goals for laptops, servers, desktops and embedded systems. 2 Section1: Linux Operating System Introduction Linux, one of the free open source operating system does sufficient memory management activities to keep the system stable and users demand for errors free. As processes and threads executes, they read instructions from memory and decode it. In such act, instructions would be fetched or store contents of a location in a memory. Then, the processor would execute the instructions which in either way the memory would be accessed in fetching instructions or storing the data. Linux uses a copy-on-write scheme. If two or more programs are using the same block of memory, only one copy is actually in RAM, and all the programs read the same block. If one program writes to that block, then a copy is made for just that program. All other programs still share the same memory. Linux handles memory in such a way that when RAM is not in use, the operating system uses it as disk cache. Below diagram illustrate a brief overview of Linux operating system. C:UsersuserDesktopimages.jpg 3 Memory Management The term memory management refers to the one of the most important parts of the operating system. It consider in provision of memory-related services to applications. These services include virtual memory (use of a hard disk or other non-RAM storage media to provide additional program memory), protected memory (exclusive access to a region of memory by a process), and shared memory (cooperative access to a region of memory by multiple processes). Linux memory management does use the platform of Memory Management Unit which translate physical memory addresses to liner ones used by the system and page fault interrupt are requested when the processor tries to access to memory that is not entitled to. Virtual Memory Virtual memory of Linux is using a disk as an extension of RAM therefore that the effective size of convenient memory grows respectively. The kernel will write the substance of a currently dormant block of memory to the hard disk so that the memory can be used for another function. When the original contents are necessary again, they are read back into memory. This is all made completely transparent to the user; programs running under Linux only see the larger amount of memory available and dont notice that parts of them reside on the disk from time to time. Obviously, reading and writing the hard disk is slower (on the order of a thousand times slower) than using real memory, so the programs dont run as fast. The part of the hard disk that is used as virtual memory is called the  swap space. Virtual memory system consist of all virtual addresses not physical addresses. These virtual addresses are transformed into physical addresses by the processor based on information held in a set of tables maintained by the operating system. To make this conversion easier, virtual and physical memory are shared into handy sized pieces called pages. These pages are all the same size, if they were different size, the system would be very hard to administer 4 The schemes for Memory Management The simplicity of Linux memory model facilitates program implementation and portability in different systems. There exist two schemes for implementation of memory management in Linux; 1.Paging 2.Swapping Paging Demand Paging Currently, saving is done using physical memory by virtual pages when compiling a program. In latter case when a program runs to query a database, not all database will respond, but only those with data records to be checked. For instance a database request for search query will only be loaded and not database with programs that works to add new records. This is also referred to as demand paging. The purpose of using demand paging is to load performing images into a process of virtual memory. Every time when a command is accomplished, the file containing it is opened and its contents are displayed into the processs virtual memory. Memory mapping is executed by modifying the data structure which is describing this process. Even so the rest of the image is left on disk ,only the first part of the image is actually sent into physical memory. Linux uses memory map to identify parts of image to load into memory by generating page faults as the image executes. 5 C:UsersfoxDesktopmmu-vs-iommu-memory.png Page Faults Page fault exception are generated when a process tries to access an unknown page to memory management unit. The handler goes further in examining the currently running process`s memory information and MMU state, then determines whether the fault is good or bad. As good page faults cause the handler to give more memory to the process, the bad faults invoke the handler to terminate the process. From good page faults are expected behaviour to whenever a program allocates a dynamic memory to run a section of code, write a for the first time a section of data or increases its stack size. In such a case when a process tries to access this newly memory, page fault is declared by MMU and the system adds a fresh page of memory to the process`s table. The interrupted process is the resumed. In cases where a process attempt to access a memory that its doesnt own or follows a NULL pointer then bad faults occur. Additionally, it could also be due to bugs in the kernel in which case the handler w ill print an oops information before terminates/killing the process. 6 Swapping Linux separates its physical RAM (random access memory) into pieces of memory called pages. The process of Swapping is accomplished by copying a page of memory to the preconfigured space on the hard disk, known as a swap space, to exempt that page of memory. The combined sizes of the physical memory and the swap space is the amount of virtual memory available. Swapping is done mainly for two reasons; One is insufficient memory required by the system when physical memory is not available. The kernel does swaps out the less used pages and supply the resources to currently running processes. Second, a significant number of the pages used by an application during its start-up phase may only be used for initialization and then never used again. The system can swap out those pages and free the memory for other applications or even for the disk cache. Nevertheless, swapping does have a disadvantage. If Compare with memory, disks are very slow. For example, memory speeds are measured in nanoseconds, but disks are measured in milliseconds, so admittance to the physical memory can be significantly faster than accessing disk. It depends how often swapping occurs, if it happens frequently your system will be slower. Sometimes excessive swapping or thrashing occurs where a page is swapped out and then very soon swapped in and then swapped out again and so on. In such situations the system is struggling to find free memory and keep applications running at the same time. In this case only adding more RAM will help. There are two forms of swap space: the swap partition and the swap file. The swap partition is a substantive section of the hard disk which is used only for swapping; other files cannot locate there. A special file in the file system which stands amongst your system and data files called a swap file. 7 Problems of virtual memory management in Linux There are several possible problems with the page replacement algorithm in Linux , which can be listed as follows: à ¢Ã¢â€š ¬Ã‚ ¢ The system may react badly to variable VM load or to load spikes after a period of no VM activity. Since the Kswapd, the page out daemon, only scans when the system is low on memory, the system can end up in a state where some pages have reference bits from the last 5 seconds, while other pages have reference bits from 20 minutes ago. This means that on a load spike the system have no clue which are the right pages to evict from memory, this can lead to a swapping storm, where the wrong pages are evicted and almost immediately after towards faulted back in, leading to the page out of another random page, etc. à ¢Ã¢â€š ¬Ã‚ ¢ There is no method to prevent the possible memory deadlock. With the arrival of journaling and delay allocation file systems it is possible that the systems will need to allocate memory in order to free memory, that is, to write out data so memory can become free. It may be useful to introduce some algorithm to prevent the possible deadlock under extremely low memory situation. Conclusion All in all, Linux memory management seems to be effective than before and this is based on the assumption that Linux has less applications that it runs as to compared to windows machines which has more users and more applications. Beside, the system may react badly to variable VM load However, regular updates from Linux has managed to lessen the bugs. Swapping does require more disk memory in case the physical memory is insufficient to serve more demanding applications and if the disk space is too low the user runs the risk of waiting or kill other process for other programs to work. Additionally, resuming the swapped pages may result into corrupted data, but Linux has been in upper hand to solve such bugs. 8 Frequently Ask Questions What is the main goal of the Memory Management? The Memory Management Unit should be able to decide which process should locate in the main memory; should control the parts of the virtual space of a process which is non-core resident; responsible for monitoring the available main memory and for the writing processes into the swap device in order to provide more processor fit in the main memory at the same time. What is called a page fault? Page fault appear when the process addresses a page in the working set of the process but the process is not able to locate the page in the working set. To overcome this problem kernel should updates the working set by reading the page from the secondary device. What is the Minimum Memory Requirement? Linux needs at least 4MB, and then you will need to use special installation procedures until the disk swap space is installed. Linux will run comfortably in 4MB of RAM, although running GUI apps is impractically slow because they need to swap out to disk. 9 Section 2: Microprocessor Introduction Microprocessor incorporates all or most of the functions of Central Processor Unit (CPU) on a single integrated circuit, so in the world of personal computers, the terms microprocessor and CPU are used interchangeably. The microprocessor is the brain of any computer, whether it is a desktop machine, a server or a laptop. It processes instructions and communicates with outside devices, controlling most of the operation of the computer. How Microprocessors Work Microprocessor Logic A microprocessor performs a collection of machine instructions that tell the processor what to do. A microprocessor does 3 main things based on the instructions: Using its ALU (Arithmetic/Logic Unit), a microprocessor is able to perform mathematical operations like addition, subtraction, multiplication and division. A microprocessor is able to move data from one memory location to another. A microprocessor is able to make decisions and jump to a new set of instructions based on those decisions. 10 The following diagram shows how to extremely simple microprocessor capable of doing of 3 jobs. The microprocessor contains: An address bus that sends an address to memory A data bus that can sends data to memory or receive data from memory A RD (read) and WR (write) line to tell the memory whether to set or get the address A clock line lets a clock pulse sequence the processor A reset line that resets the program counter to zero and restarts execution 11 Here the explanation of components and how they perform: Registers A, B and C are kind of latches that made out of flip-flops The address latch is just like registers A, B and C. The program counter is a latch with the extra capacity to increment by 1 when or reset to zero it is needed. Major trends which affect microprocessor performance and design Increasing number of Cores: A dual-core processor is a  CPU  with two processors or execution cores in the same  integrated circuit. Each processor has its own  cache  and controller, which enables it to function as efficiently as a single processor. However, because the two processors are linked together, they can perform operations up to twice as fast as a single processor can. The Intel Core Duo, the AMD X2, and the dual-core PowerPC G5 are all examples of CPUs that use dual-core technologies. These CPUs each combine two processor cores on a single silicon chip. This is different than a dual processor configuration, in which two physically separate CPUs work together. However, some high-end machines, such as the PowerPC G5 Quad, use two separate dual-core processors together, providing up to four times the performance of a single processor. 12 Reducing size of processor Size of the processor the one of the major trend what is affecting to the processor in last years time. When the processor becoming small there will be many advantages like it can include many cores to a processor, it will protect energy, it will increase its speed also. 45nm Processor Technology Intel has introduced 45nm Technology in Intel Core 2 and Intel Core i7 Processor Family. Intel 45nm High-K Silicon Processors contain Larger L2 Cache than 65nm Processors. 32nm ProcessorTechnology At research level Intel have introduced 32nm processor (Code Name Nehalem- based Westmere) which will be released in 2nd quarter of 2009 Energy saving Energy is one of the most important resources in the world. Therefore we must save and protect it for future purpose. The power consumption in microprocessor would be one of the major trends. For instance, Intel Core 2 family of processors are very efficient processor, they have very intelligent power management features, such à Ã‚ °s, ability to deactivate unused cores; it still draws up to 24 watts in idle mode. 13 High speed cache and buses In Past year Microprocessor Manufactures like Intel has introduced new cache technologies to their processors which can gain more efficiency improvements and reduce latency. Intel Advanced Smart Cache technology is a multicore cache that reduce latency to frequency used data in modern processor the cache size is increased up to 12MB installing a heat sink and microprocessor 14 Differences between Microprocessors Servers Originally the microprocessor for server should give uninterrupted time and stability with low power consumption and less resources allocating processor for System Cache. Thats why most of the time they use Unix and Linux as the Server based operating systems, because they take less amount of hardware resources and use effectively so the heat which dispatches from the processor is less and the heating would be less. Desktop Processors The desktop microprocessors are a bit different from server microprocessors, because they are not very much concerned of power consumption or use less resources of Operation system. The goal of Desktop microprocessors is to deliver as much performance as possible while keeping the cost of the processor low and power consumption within reasonable limits. Another important fact is out there, it is most of the programs which are being used in desktop machines are designed to do long time processor scheduling jobs like rendering a high definition image, or compiling a source file. So the processors are also designed to adopt those kinds of processing. Laptop Processor The CPU produces a lot of heats, in the desktop computers there are a systems of fans, heat sinks, channels and radiators that are uses to cool off the computer. Since laptop has small size, and far less room for any cooling methods, the CPU usually: Runs at a lower voltage and clock speed (reduces heat output and power consumption but slows the processor down) Has a sleep or slow-down mode (when the computer is not in use or when the processor does not need to run as quickly the operation system reduces the CPU speed) 15 Embedded Microprocessors Most of the embedded devices using Microcontrollers instead of separate Microprocessors; they are an implementation of whole computer inside a small thumb size chip called Microcontroller. These microcontrollers are varying its performance due to battery consumption and Instruction length issues. Most of them are designed using RISC architecture to minimize the complexity and the number of instructions per processor. Embedded device processors have high speed potential but the problem they are having is high power consumption and heating. Conclusion Current technology allows for one processor socket to provide access to one logical core. But this approach is expected to change, enabling one processor socket to provide access to two, four, or more processor cores. Future processors will be designed to allow multiple processor cores to be contained inside a single processor module. 16 Frequently Ask Questions: 1. How does the operating system share the cpu in a multitasking system? There are two basic ways of establishing a multitasking environment; times lice and priority based. In a a times lice multitasking environment each application is given a set amount of time (250 milliseconds, 100 milliseconds, etc) to run then the scheduler turns over execution to some other process. In such an environment each READY application takes turns, allowing them to effectively share the CPU. In a priority based environment each application is assigned a priority and the process with the highest priority will be allowed to execute as long as it is ready, meaning that it will run until it needs to wait for some kind of resource such as operator input, disk access or communication. Once a higher priority process is no longer ready, the next higher process will begin execution until it is no longer ready or until the higher priority process takes the processor back. Most real-time operating systems in use today tend to be some kind of combination of the two. 2.What is a multi-core? Two or more independent core combined into a single package composed of a single integrated circuit is known as a multi-core processor. 3. What is the difference between a processor and a microprocessor? generally, processor would be the part of a computer that interprets (and executes) instructions A microprocessor, is a CPU that is in just one IC (chip). For example, the CPU in a PC is in a chip so it can also be referred to as microprocessor. It has come to be called a microprocessor, because in the older days processors would normally be implemented in many ICs, so it was considered quite a feat to include the whole CPU in one chip that they called it a Microprocessor 17

Neurobiological Mechanisms that Cause Aggression

Neurobiological Mechanisms that Cause Aggression Review of the Neurobiological Mechanisms Which Underpin Reactive Aggression in Humans: a Closer Look at Monoamine Oxidase A (MAOA) Module 1: Prosocial and antisocial behaviours across the lifespan Violent acts have a significant toll on human societies: annually over 1.6 million deaths worldwide occur due to human violence (Viding Frith, 2006). Although acts of aggression have an important adaptive purpose, when overexpressed, they may result in destructive consequences. Conventionally, aggression has been defined as an intentional action with a purpose to inflict physical damage on another individual (Nelson Trainor, 2007). Currently two forms of aggression have been recognized in humans: controlled aggression instrumental subtype, and reactive aggression impulsive subtype (Vatiello Stoff, 1997). Instrumental aggression, also referred to as premeditated and predatory, is generally planned and goal-oriented and has often been linked to psychopathy (Blair, 2001). This kind of aggression is thought to be regulated primarily by higher cortical systems and is characterized by diminished amygdala response (Nelson Trainor, 2007). Reactive aggression on the other hand, is depen dent on the limbic and hypothalamic systems, and is characterized by high autonomic arousal (Siever, 2008). Impulsive aggression generally represents a direct response to stimuli and accounts for the majority of violent acts. Individuals with borderline personality disorder, intermittent explosive disorder, or ADHD are particularly prone to reactive aggression and impulsivity. Previous research on the neurobiology of aggression pointed out that for such individuals, repetitive acts of aggression are often influenced by the underlying neurobiological susceptibility (Nelson Trainor, 2007). Indeed, one remarkable feature of aggression is its apparent heritability. Twin and adoption studies suggest that genetic factors account for between 40% and 50% of population variance in risk of antisocial aggression (Buckholtz Meyer-Lindenberg, 2008). However, the relationship between aggression and the underlying neurobiology is far from being simple (Nelson Trainor, 2007; Siever, 2008). Previous research in individuals prone to impulsivity and reactive aggression as well as a number of studies based on animal models identified numerous genetic loci and neurotransmitters associated with reactive violence, including, but not limited to, Dopaminergic genes (DRD4, DRD5, and DAT1), Serotonergic genes (5HTT, HTR1B), and genes responsible for encoding enzymes involved in regulating the levels of these neurotransmitters, particularly catechol-O-methyltransferase (COMT), and Monoamine Oxidase A (MAOA), often referred to as â€Å"the warrior gene†. However, the association between genotype and phenotype of aggression is only beginning to be properly understood (Caspi, McClay, Moffitt, Mill, Martin, Craig, Taylor, Poulton, 2002; Nelson Trainor, 2007; Siever, 2008). While there have been many studies showing the association between different genes and aggression, results were often mixed and inconclusive. Currently, the best candidate gene with the most supportive evid ence appears to be Monoamine Oxidase A (see: Brunner, Nelen, Breakefield, Ropers, van Oost, 1993; Byrd Manuck, 2014; Cases, Seif, Grimsby, Gaspar, Chen, Pournin, Muller, et al.,1995; Caspi, et al., 2002). The MAOA gene, located on the X chromosome, is a functional polymorphism with high activity (MAOA-H) and low activity (MAOA-L) variants, which encodes the MAOA enzyme, responsible for breaking-down neurotransmitters such as serotonin, dopamine, and norepinephrine (Shih, Chen, Ridd, 1999; Viding Frith, 2006). Previous research using animal models as well as humans demonstrated an association between aggression and genetic deficiency in MAOA activity (Rowe, 2001). Transgenic mice without the gene encoding MAOA had higher amounts of brain serotonin (5-HT), dopamine (DA), and norepinephrine (NE), and displayed increased aggression (Cases, et al., 1995). After restoring MAOA activity, mice aggression was stabilized (Shih Thompson, 1999). In humans, point mutation in the MAOA gene led to MAOA deficiency and was found to be associated with reactive aggression in several men from the Dutch family. Moreover, across generations, these men with MAOA knockout also showed frequent violent outb ursts, particularly in response to mild provocation, and impulsive antisocial behaviour such as assault, rape, and attempted murder. (Brunner, et al., 1993). This condition, however, is quite uncommon and is unlikely to explain much variation in human violence and aggression. Findings of the studies that only looked at levels of MAOA activity and antisocial outcomes in adulthood have been mixed and thus problematic to interpret since both MAOA-H and MAOA-L were linked to reactive aggression (Ficks Waldman, 2014; Nelson Trainor, 2007; Siever, 2008). The study that produced very robust findings in that area and has later proven seminal was conducted by Caspi and colleagues (2002). This study was the first to look at the effects of MAOA activity in combination with childhood maltreatment on reactive aggression in adulthood. Indeed, adverse childhood experiences were found to affect the development and functioning of neural pathways involving the neurotransmitters metabolised by MAOA which can potentially result in increased aggression (Caspi, et al., 2002). Thus, Caspi and colleagues (2002) hypothesised that childhood maltreatment can predict reactive aggression in adulthood, and that this relationship is moderated by levels of MAOA expression. Results of this study demonstrated the dose-response effect of childhood maltreatment on the aggressive behaviour in adulthood, which was consistent with prior findings. However, this effect was much smaller in participants with the high-activity version of the MAOA gene as compared to men with low MAOA activity, suggesting the protective property of MAOA-H (Caspi et al, 2002). Moreover, as levels of maltreatment increased, so did the protective effect of the MAOA-H variant. A low-activity MAOA gene combined with a history of childhood maltreatment increased the risk of aggressive behaviour in adulthood sevenfold. These results supported the predicted hypothesis that MAOA activity would act as a moderator of the effects of childhood maltreatment on antisocial outcomes in adulthood. This study paved the way to a number of subsequent studies looking at gene and environment interaction. A recently published meta-analysis, which looked at 27 peer-reviewed studies on adverse childhood experiences, MAOA genotype, and aggressive and antisocial behaviour showed that results across 20 male cohorts (11064 participants) were largely consistent with findings from the original study by Caspi and colleagues (2002) (Byrd Manuck, 2014). These findings remained robust even after removing each study individually. However, the question remains, how does low activity MAOA gene in combination with childhood stressors translate to antisocial behaviours in adulthood? Several theories have been proposed to answer this question. On one hand, the association between low activity MAOA gene and aggression appears paradoxical, since MAOA-L leads to increased levels of serotonin, which has been found to be positively correlated with impulse control and negatively correlated with aggression (Manuch, Flory, Ferrell, Mann, Muldoon, 2000; Siever, 2008). However, MAOA also plays a role in regulating dopamine and norepinephrine, which were shown to lower thresholds for violent response to perceived threat (Manuch, et al., 2000). High levels of DA and NE, resulting from MAOA dysfunction, would activate a fight or flight response, and indirectly enhance aggression (Volavka, Bilder, Nolan, 2004). Indeed, previous studies showed a similar association between COMT gene (also responsible for breakdown of NE and DA ) and aggression (Siever, 2007; Volavka, et al., 2004). Therefore the elevated levels of NE and DA, due to low expression of MAOA, would be consistent with the results of previous studies, showing an association between low activity MAOA gene and aggression. Nevertheless, this theory does not account for the role of childhood maltreatment on aggression, and as it was mentioned previously, results of studies looking solely at MAOA activity and aggression are mixed and inconclusive, showing both high and low activity MAOA gene being associated with impulsive aggression (Ficks Waldman, 2014; Nelson Trainor, 2007; Siever, 2008). Another theory that sheds more light on the mechanism through which MAOA deficiency in combination with childhood maltreatment influences aggression in adulthood relies on the findings that high concentrations of intracellular serotonin have been associated with increased reactivity to stress and elevated anxiety (Seif De Maeyer, 1999, Viding Frith, 2006). Therefore, it is possible that MAOA deficiency might predispose individuals to neural hyper-reactivity to a threat (maltreatment). While genetic predisposition alone rarely results in adverse outcomes in adulthood, when combined with childhood stressors, it might potentially have consequences on brain function (Meyer-Lindenberg, Buckholtz, Kolachana, Hariri, Pezawas, Blasi, Wabnitz, et al., 2006). Previous findings in populations prone to impulsive violence demonstrated functional and structural abnormalities in brain areas associated with perception and regulation of emotions, particularly in the amygdala, orbitofrontal cortex, and the interconnected regions (Davidson, Putnam, Larson, 2000). Neuropsychological functions associated with these brain regions were also compromised in the aforementioned populations (Blair, Peschardt, Budhani, Mitchell, Pine, 2006). Previous work using animal models and clinic samples seems to suggest that maltreatment negatively affects the functioning of the neural structures involved during an individual’s reaction to threat (i.e., pariaquaductal gray and amygdala) and the regulation of the triggered threat response (i.e., orbitofrontal cortex and anterior cingulate). Therefore, the genetic risk (MAOA-L) along with childhood maltreatment may result in changes to brain function, and subsequently increases the risk of impulsive aggression (Viding Frith, 2006). These speculations imply that there is no one clear explanation for the findings we currently have regarding genetic variation and its effect on aggression. The human brain and the effects of genetic and environmental factors on its development are too complex to assume that one specific gene, or neurotransmitter levels are responsible for aggression. More likely, it is the gradual change in neural pathways that regulate aggression. As of this moment, it still remains unclear if aggression in adulthood that is observed in many of the aforementioned studies is due to developmental change in neural circuits or to a change in neurotransmitter function. Moreover, the effects of these changes for adults are very different than for children. Therefore, it is possible that low MAOA activity resulted in compensatory changes which transformed the organisation of the nervous system in children during the sensitive period of brain development, and was later reflected in antisocial outcomes in a dulthood (Lesch Merschdorf, 2000). Attempts to replicate Caspi et. al. (2002) findings in female populations yielded significantly different results. Recent meta-analysis that looked at 11 studies with female samples produced inconclusive results: even though MAOA activity had a significant association with adverse childhood events, high, as opposed to low, MAOA activity in combination with childhood maltreatment was associated with antisocial behaviour in adulthood. Moreover, this interaction was weaker, and after removing a few individual studies, it lost its significance (Byrd Manuck, 2014). Replicating Caspi and colleagues’ study using female cohorts has proven to be significantly more complicated for two main reasons. First of all, dividing females into two groups based on MAOA activity is challenging due to uncertain inactivation of heterozygous alleles. Secondly, severe personality disorders and antisocial outcomes are quite rare in women, thus it is difficult to get a large enough sample to demonstrate dose-response relationships. In sum, taking into account findings from previous studies it is unclear what relationship MAOA activity plays in antisocial outcomes in women, and calls for further investigation (Caspi, et al., 2002; Byrd Manuck, 2014). In attempts to understand the relationship between genes, environment, and aggression, the study by Caspi and colleagues (2002), as well as numerous studies that came out afterward, certainly advanced our understanding in the field. However, it is important to point out the limitations that characterise many of the research studies investigating the relationship between gene-environment interaction and adult antisocial behaviour. First of all, lack of published articles reporting null findings due to publication bias still remains a big problem in the field. As a result, published findings seem more robust than they actually are (Duncane Keller, 2011). Secondly, the samples of many studies, primarily those with female subjects, are often too small resulting in inadequate statistical power (Byrk Manuck, 2014). Indeed, negative findings had larger sample sizes compared to positive ones. These limitations make it difficult to correct for potential false-positive results (Duncan Kelle r, 2011). This is especially the case in replication attempts using female populations, and in neuroimaging studies. Finally, due to the difficulty recruiting participants for these studies, samples are often not easily comparable and consist of individuals with many comorbid psychiatric conditions, making it difficult to tease apart effects of certain genetic variations and maltreatment on specific psychopathology (McCrory, DeBrito, Viding, 2010). While there is strong evidence to suggest that genotype, particularly variants of the Monoamine Oxidase A gene, in combination with childhood maltreatment, plays an important role in reactive aggression in human adulthood, the exact underlying mechanism remains unclear. The aforementioned controversies call for caution when making any strong conclusions regarding the effects of genetic variation on antisocial outcomes. Further research, including longitudinal studies, genome-wide association studies, gene-environment-sex and gene-gene interaction studies, and neuroimaging studies, is necessary to better understand the underlying neurobiological mechanisms which underpin reactive aggression in humans.

The Decoration of Houses Essay -- Literary Analysis, Edith Wharton

In Edith Wharton’s first major work, The Decoration of Houses, she states that â€Å"the impression produced by a landscape, a street or a house should always, to the novelist, be an event in the history of the soul† (qtd. in Falk 23). Later in her Pulitzer-winning novel The Age of Innocence, Wharton uses her knowledge and love of architecture to develop her characters, as she had previously deemed important. Thus, she takes style of houses, their design, and their European or American identification into consideration and depicts characteristics of the New York society and the major characters. Ranks in the social order are shown based on where in the New York district a character lives, personalities of aristocrats that are cold are shown through plain walls and furnishings, and some characters are separated from society because they follow different strains of architecture and interior design. At the beginning of the novel, Beaufort’s house quickly stands out as a character who earned his place in society through the architecture of his home. It is the first described and â€Å"one of the few in New York that possess[es] a ballroom . . . this undoubted superiority [is] felt to compensate for whatever [is] regrettable in the Beaufort past† (13). This characterizes the upper class society of New York. Clearly, architecture must be important if a ballroom guarantees someone a high rank, and it can even cover up the fact that Beaufort was not born into the social order and has a mistress. Ada Van Gastel, a Wharton critic who wrote â€Å"The Location and Decoration of Houses in The Age of Innocence,† points out another way that Beaufort’s property represents him: â€Å"Having only recently entered society, he still resides on the ... ...lot, yet at this point, he is identified with New York. He tries to break away later, but like the plot of the novel, he cannot leave America or the architecture attributed to it. Wharton artfully uses her love of architecture in The Age of Innocence. She shows some characters as elite but plain New Yorkers, just like their house. Beaufort uses his to break into society, but he never quite fits. All the same, Archer cannot be characterized as directly. He wants to be European, like Ellen Olenska and Catherine Mingott, but it does not work. Architecture seems to confusedly describe him in this, which portrays his own confusion with it. It may also show Edith Wharton’s uncertainty on whether she liked his character or not. In the end, when she announces that he will never fit in with the European characters, maybe she is deciding her view of him.

Comparing Heart of Darkness and Apocalypse Now :: Movie Film comparison compare contrast

Comparing Heart of Darkness and Apocalypse Now   Heart of Darkness written by Joseph Conrad and "Apocalypse Now" a movie directed by Francis Coppola are two works that parallel one another but at the same time reflect their own era in time and their creator's own personal feelings and prejudices. "Apocalypse Now" was released in 1979 after two years in the making, as Coppola's modern interpretation to Joseph Conrad's novel, Heart of Darkness (Harris). Conrad's book is an excellent example of the advances writers and philosophers made in the nineteenth and early twentieth centuries. This advance deals with civilized humanity's ability to be prepared for and know the unknown. (Johnson) Comparatively, Copolla's movie does the same in the late 1970's. "Apocalypse Now" dares to breach the edges of soldier sanity in a stressful and protested Vietnam War. One of the many similarities between Heart of Darkness and "Apocalypse Now" is race. Joseph Conrad and Francis Coppola both use white men as the characters that have dominance (Bradley). The white men not only dominate their respective crews, but also the peoples native to the country the white men are visiting. The character Conrad uses, Marlow, and Coppola uses his character, Willard, both look at the natives as though white men are the civilized culture and the native people are the savage culture (Franklin). Both works also reflect the theory that "civilized" white men that go into an uncivilized land become savage and do not return to white civilization. An example of this that is in the book is MarlowÕs appointment with the doctor. The doctor measures Marlow's skull to compare its size at the present time to the size of his skull upon his return from the Congo. The thought is that a civilized manÕs skull is a different size than a savage's skull. When Marlow asks the do ctor how what the results of this test have been in the past, the doctor comments that there are none because no civilized person has ever returned from the Congo. An example of this in the movie is when Willard faces his own personality of whether or not to complete his soldierly mission of killing Kurtz or to abort it. If he completes the mission he is still civil, if he does not, the Vietnam jungle has conquered him. The first soldier that is sent to kill Kurtz did not kill Kurtz, but in fact became one of his followers.

Baptist Bible Fellowship International :: bible colleges, chruch, fellowship

The Baptist Bible Fellowship International has done great things throughout the many years of its existence. The reason for the group’s success has been through missions, evangelism, Bible Colleges, and church planting. In the 1950’s the World Baptist Fellowship ruled the Baptist scene. During the era of the WBF there was a conflict that arose as J. Frank Norris attempted to overthrow G.B. Vick’s presidency at his Bible College. Norris desired to be president of the college that Vick established. Norris attempted to push Vick out by spreading rumors and causing dissension regarding Vick’s character among the students that attended the college. Jeffery D. Lavoie writes in, Segregation and the Baptist Bible Fellowship, that G.B. Vick aided a â€Å"movement† for a new fellowship after being removed from his presidency by J. Frank Norris. When about one hundred pastors decided leave the WBF and start a new fellowship. With the leadership of Vick and t he other pastors, a brand new fellowship called the Baptist Bible Fellowship was created in May 1950 (Lavoie 2). The WBF was the most prominent fellowship among Baptist pastors, and slowly after the BBF was formed, the WBF faded away. To this day is still existing and running as a missions agency. As time passed, the BBF had the desire to communicate the need for missions and missionary help. In 1975, in order to raise the awareness of missions, the BBF changed the name from, Baptist Bible Fellowship, to Baptist Bible Fellowship International or BBFI. The reason for the name change was to emphasize missions among the group of pastors (Lavoie 3). This change of heart and emphasis helped in creating some of the greatest missionaries the world has ever seen. The Baptist Bible Fellowship International produced an abundance of great missionaries, while all missionaries deserve their honor and dues: three of the most influential missionaries from the BBFI are John Birch, Fred Donnelson, and Bob Hughes. One of the most influential missionaries within the BBFI is John Birch, whom God brought to the world on May 28th, 1918, in Landour, India. Mike Randall the writer of an article in Our Baptist Heritage about John Birch explains how John Birch’s parents, George Birch and Ethel Birch, taught at Ewing Christian College in Allahabad, India. George suffered from chronic health problems, but that problem did not stop them from completing at least three years of ministry in India.

No one knowingly does evil: an essay on the Socratic principle

The contention that no one knowingly does evil is one of the most fundamental principles championed by Socrates. The very essence of this Socratic principle dwells on the assumption that if a man understands very well that such and such acts are wrong or result to evil, or such that if a man is indeed aware in the first place that this action is wrong in the strictest sense of the word, then that man will tend to revert himself away from committing the act. Socrates stalwartly advances his pivotal idea that men in general cannot, in any conceivable manner, transform man into being fully wise or utterly foolish.Rather, men are inclinedto perform actions at an unfixed and random way, with no great propensity to be inclined to do more evil or to do more good. Consequently, an inexhaustible capability for performing either good or bad conducts is what men do not fundamentally possess. Another principal feature of Socrates’ thoughts is his claim that knowledge is directly associate d to that which is good and that ignorance is tied to that which is evil. Thus, it can be clearly observed that by claiming that no one knowingly does evil what is being meant is that to know and understand one’s actions is to understand that which has goodness.Since ignorance is significantly affixed to evil, Socrates observes, then, that no one knowingly does evil. In instances where man acts, it is immaterial for one to put great emphasis on the goodness or evilness of the action itself. What one should all the more consider is whether such actions are either within the proximity of being just or unjust and not necessarily that of being good or evil. In general, what Socrates is trying to point out is that the very causes of evil acts can ultimately be drawn from ignorance. For example, revulsion of one person to another person results from misapprehension, from ignorance of the related facts.Further, the Socratic assertion that no one knowingly does evil refutes normal re lativism for a few several points. Given such Socratic principle, it implies that it applies to all men who have the innate capacity to act. Likewise, to assert that no one knowingly does evil is to assert as well the claim that human beings by nature cannot be consciously aware that they are doing evil and that, instead, they assume that they are acting in order to amplify pleasure. The term â€Å"no one† in the phrase obviously refutes any relative conception of the principle since â€Å"no one† refers to that which is universal.To have relative views, then, on what actions count as evil and good is to essentially refute the claim that no one does evil voluntarily and willingly, and vice versa. Several contemporary counter-examples can be given to attempt at refuting the Socratic principle. Apparently, suicide, terrorism and sadism all have one thing in common in the context of Socrates’ principle no one knowingly does evil: they purport to exemplify cases whe rein human beings appear to be capable of doing evil with their knowing.All these three may in fact provide crucial grounds for claiming that men have the potential and the actual capacity to inflict harm and do evil while they are fully aware of these actions. However, we might go on to argue that men in these instances are ignorant of the good. Yet, even if they are ignorant of the good, it does not necessarily follow that they know sadism, suicide and terrorism as evil deeds for the fact that no one identifies what is good without actually noting those which are evil or have the actions which have the propensity to result in evil.Thus, these actions could not have been evil in the first place if one has no sense of what it is that is deemed to be good. It might be held valid and true that people who engage themselves in these actions have a leaning towards the evil as others may view them to be, but nevertheless these very people who are a part of the actions are ignorant of the evil that they might have been doing. This is pegged on the presupposition that men have the mental framework that the things they do are aimed at obtaining that which incites pleasure.For the most part of the claims of Socrates, there are hardly any strong refutations which might prove to be callous enough to dismantle the ancient philosopher’s arguments. There is a deep sensibility in Socrates’ dialogues with his fellowmen in the Apology as with the other parts of Plato’s Republic such that, with the Socratic method of inquiry, one arrives at an understanding about one’s little knowledge, that much is left to be understood and that only through a removal of one’s ignorance can one begin to achieve genuine knowledge.

Enterprise Architecture as Strategy Essay

Technology is shifting at a faster rate resulting in development of new methods that assist in satisfactory completion of certain technological demand. This has given birth to different enterprise architecture frameworks that fulfill the specific requirements of day-to-day activities. Architecture is a framework of guidelines, principles, models, standards and strategies that directs, social construction and development of business process, design and information and resources through enterprise. Hence, free enterprise architecture is a blueprint, which defines the structure and operation of a given organization (Fowler & Rice 2003).The growth of such a economic theory isnt sufficient.The Open Group Architecture Framework (TOGAF) is an enterprise architecture framework, which approaches the further development of enterprise information architecture through design, planning, governance and implementation.This EA framework employs twenty four pillars to achieve its goals: Applicati on, Business, Technology and Data. Before the architect own plans for current and future aims of the organization, they are provided with foundation architectures how that form the basis that they will use for the new development. The four pillars play a crucial major role in ensuring that the process is successful.Management is merely one of the essential pursuits which play a valuable part in the additional information systems also .

The original aim of the TOGAF was to design and develop technology modern architecture for a given business entity. However, the framework has evolved becoming a methodology that is used to analyze overall business architecture. This resulted into splitting of the enterprise methodology into two parts: Architecture further Development Method (ADM) and Enterprise continuum. The ADM ensures that the enterprise architecture meets the minimum requirements of the organization in terms of business needs and information technology needs.Information methods that what are complex control leverage new technologies and concepts or companies from having the ability to adapt to be able to compete.For example, Phase C combines Application and available Data architecture and phase B and C ensure that the clarity of the information gothic architecture is achieved (Lankhorst 2005).For the ADM to be successful, Enterprise Continuum comes handy. Generally, the Enterprise Continuum can be seen as a ‘virtual repository’ of all the assets of the architecture that is in an organization. These assets may include architectural patterns, architectural models, architecture descriptions and other important artifacts.At best, it tap into a diverse range of abilities and solutions empty can result in a more holistic strategy and also improve the overall understanding of our professionals.

Usually there is a relationship between the different EA frameworks in terms of how it operates and ways deeds that enables it to accomplish its duties. Zachman Framework and TOGAF ADM part fair share some common features. ADM mapping in relation to the Zachman Framework supports a correlation.The Zachman Framework has a well established and comprehensive taxonomy that supports various models, viewpoints wired and other important artifacts, which an enterprise may consider developing as a phase of the EA (White 2007).Organizations unable to satisfy the generous donation could be requested to submit supporting documentation, including salary programs for other graduate-level interns or an operating budget.The main purpose of the architecture is to define viewpoints, an aspect that is supported by the TOGAF ADM but lacks in Zachman Framework. Zachman Framework vertical axis provides a source of potential viewpoints worth while the horizontal may provide generic taxonomy concerns. Thus, the Zachman Framework does not have means good for processes for conformant views or developing viewpoints. Hence, it does not full employ a perspective that is shown by TOGAF’s ADM.Our company is about to offer top excellent custom writing dilute solutions to you.

Hence, the columns that are in the FEAF matrix correspond to the three gothic architecture domains that are supported by TOGAF; the fourth TOGAF domain covers business gothic architecture that lacks in the FEAF structure.Enterprise Architecture Planning (EAP) is a framework that brings together Applications, additional Information and Technology Architectures in fulfilling the requirements of architecture. Thus, it shares many concepts keyword with TOGAF because the aim of EAP is to form blueprints for architectures to solve business problems. Moreover, EAP supports the nine phases that are supported by the TOGAF (White 2007).There are a first great deal of additional ways that youll be able to use to increase how their writing abilities.Department of Defense Architecture Framework (DoDAF) defines the architecture systems into consistent and complementary views. It defines a structure logical and mechanisms that help in understanding, visualizing and assimilating the complexiti es and broad scope of a example given architecture design through tabular, graphic and textual means. Thus, it shares minimal aspect with TOGAF.In fact, TOGAF main focus on the methodology of architecture in terms of â€Å"how to† without bringing into consideration architecture description constructs.There are advantages deeds that are given to the enterprises.

DODAF requires that all information, analysis and new products to build should be put forefront before building the architecture. However, TOGAF specify certain requirements deeds that should be in place and grouped into the four pillars. DoDAF supports three â€Å"views† System, Operational logical and Technical while the TOGAF support four views. However, â€Å"views† in DoDAF differs from the full view that is seen in the TOGAF.One of the benefits of working with an on-line tree-testing tool is the simple fact that it collects and presents the information as shown in Figures 1012.Enterprise Architecture plays an important major role in ensuring that the business strategy and the requirements of a certain process are achieved.TOGAF approach is useful in achieving a business-oriented process through a well defined methodology. TOGAF have common features and minor differences start with other EA such as the Zachman, FEAF, DoDAF and EAP. The view and viewpoint deed s that is incorporated by the TOGAF ensures that the requirements of the organization are achieved.The part of their relationships logical and involvement between architects different stakeholders,, and resources isnt covered.
