Trends in Computer Architecture Essay -- essays research papers fc
Trends in Computer Architecture Since the introduction of the first computer, the search for computer architecture that is faster, smaller, and more efficient has been a constant goal of the computer industry. The first computers were large, heavy machines composed of thousands of vacuum tubes. The development of the transistor created the next evolution in computer architecture, the microchip. This is the architecture used in the current generation of computers. Like its vacuum tube predecessor, this architecture of utilizing transistors, can only go so far. Mooreââ¬â¢s Law predicts that the number of components on a chip doubles every 18-24 months. At this rate each switch will eventually become the size of an atom. When this happens the laws of quantum mechanics must be used. A new evolution in computer architecture will need to be developed to handle the unique laws of quantum mechanics. This architecture is already being developed and is called a quantum computer. Quantum computers work in a rather distinctive way. Instead of using traditional bits, they use quantum bits, or qubits. These qubits are particles that can take on the unique states required for quantum computing. The best way to understand how a quantum computer works is by example. A basic example is to take a register composed of 2 bits. Using a classic register, these two bits can have a value of 0,1,2, or 3. Now using a quantum register with two qubits, the register can have a value of 0, 1, 2 and 3 all at ...
Globalization and genocide Essay
The twentieth century has seen a lot of inventions come into being, from the invention of the engine, to the manufacturing of airplanes. Then there came the aspect of globalization. The world that was so large started shrinking on a daily basis until finally, borders seemed to have evaporated into thin air even between continents. Today, a person may be in London in the morning and in the evening he is in Washington. Communication has also been made easier and more efficient in such a way that you can talk to a person who is thousands of miles away, as if you are talking to the person next door. The world has become a small community. Successes and failures However, there are shortcomings that have come with globalization. Lechner and Boli (2004) in their book The Globalization Reader argues that while there has been shortcoming of globalization because of the strain it has exerted on the environment thereby degrading it. While the countries all over the world have been working to see their economies develop, this has been at the expense of the environment. One of these causes of environmental degradation according to their argument is the destroying of the natural environment. Large tracts of forest covered land are destroyed each year leaving the land bare and in a few years no longer unproductive. This, they argue, is not the only cause of environmental degradation. Another cause is the releasing of harmful chemicals into the environment. Example is the Chernobyl nuclear accident. After this accident, there were many nuclear substances that were released into the environment and over the years have caused cancer. Fossil fuels have also contributed greatly to the destruction of the environment. While these have provided fuel for industries, carbon dioxide emissions has been on the rise thereby causing global warming. Are there ways and means to reverse the current trends of environmental degradation in order to make secure our future? However, despite all this destruction, there has been an effort to try and slow down if not to completely stop the rate at which the environment is destroyed. Whereas the governments have not been keen enough to conserve the environment, Lechner and Boli (2004) argue that there are environmentalists who have rallied for conservation of this precious environment. In 1992, Rio de Janeiro Declaration on Environment and Development proposed that, for a meaningful development to be achieved, environment conservation must come first. There are also who have argued that for environment to be conserved especially in poor nations, the rich nations must cancel their debts since the small governments spend all their earnings paying debts at the expense of local development, thus forcing it people to solely rely on an already deprived land hence furthering the effects of environmental destruction. Others have used all their minerals on debts without caring much on the effects this has on the environment. There are also organizations that were formed to champion for the protection of the environment. Their call is on the political class to make their priorities right by spending less on military and more on environment protection, not just for this generation but also for future generation. Issues of poverty have been cited as the biggest enemy to the protection of the environment. An example is of Mau forest in Kenya. While this forest has been the water catchments and the source of many rivers in Kenya, it faces the danger of being destroyed because of human activities. At the moment, part of the forest has been inhabited by people who are poor and therefore not willing to move out. The government of Kenya on the other hand is also unable to settle these people elsewhere since it doesnââ¬â¢t have resources. The neighboring nations namely Uganda and Tanzania face the same plight as Kenya and cannot help the Kenyan government yet these rivers drain in Lake Victoria which is shared among them. These activities that have affected a nation environmentally do not affect just one person. The Mau forest in Kenya is a good example. If the future of Mau forest is not solved, eventually, Egypt which doesnââ¬â¢t even border Kenya will be affected since it depends on water from Lake Victoria through river Nile for its irrigation. Human beings faced the danger of extinction on a daily, more so from environmental degradation. Nevertheless, it is possible to have a better world. A world where pollution is controlled and excellent environment that is not contaminated is the ultimate choice for everyone. There have been meetings called by different people all over the world to fight for the right to live in a non polluted environment. An urge to have those that are considered the minority in the society to participate in the process of policy making has been on the rise. Is it possible, when we are united together as a people, to fight for our environment? Genocide The effects of globalization have not been felt in the environmental circle alone. Social life in many places throughout the world has been altered because of globalization. According to Gellately and Kiernan (2003) examines the atrocities that have been committed against humanity, some among them committed by the ââ¬Ëcivilizedââ¬â¢ as they championed for globalization. For example, there were mass murders that were committed at Guatemala, sponsored by the US government. In this revolution, the Mayan community was massacred and the world kept mum. Even when as a commission to investigate these events was setup, their report did not reveal the motives behind these killings, and the people behind it. The Mayan people are not the only ones that have been affected. Yugoslavia in 1991 faced genocide whereby a minority group was targeted and massacred. Politics and cruelty has been the order of the day. Politicians have been known to use people to get into position and then turn against these people. These acts of brutality are yet to end. Societies throughout the world still experience mass murders in their midst. Technology, which is supposed to ease the way life, is now being used against people. US is not spared either. September 11 attacks proved that people are willing to go all the way to destroy others. While we may toy around with the idea of whether to reevaluate our stand towards globalization or not, we must always remember that a time is coming when we shall not enjoy the relaxation our beaches offer us as we do today. At that time, there will be no trees for our wildlife and therefore no rain. For countries in Sub Saharan Africa, this will mean that there will be no food since these communities have always depended on rain for their agricultural activities. Just as a reminder, that time is already at hand. We are already seeing the effects of globalization on our environment. Yet, the question we ask ourselves is, ââ¬ËAre we ready to shove the idea of globalization beneath the carpet and look for a new alternative? ââ¬â¢ Some of the greatest crimes against humanity were committed at a time when we considered the world to be on a highway to becoming one community with no barriers. That was in the mid 1990s, a genocide that left many dead with many other maimed. Yet, the global community never spoke a single word until it was all over. According to Gellately and Kiernan (2003), these acts of brutality have often been sparked by oppression through the years by those who are powerful. After many years of oppression, those who have been oppressed pour their anger on those who are helpless and vulnerable and therefore cannot defend themselves. In the end, we witness the kind of crimes like those that happened in Rwanda (p 375). We cannot also ignore the fact that technological advances in warfare have also been the cause of genocides in our communities. Cases in point are the Nazis in Germany; the use of poisonous gases against the Kurds in Iraq; the September 11 attacks on US soil. These have all employed the use of technology to perpetrate crime. Thus, the globalization that was supposed to bring us together has also been the source of death and segregation in our communities. Are we as human being going through a transition that is changing us for the worse i. e. turning us against each other? Is globalization therefore the cause of genocide or a solution to eradicating genocide in the current world? Are we our own enemies? References Lechner, F & Boli, J. (2004). The globalization reader.

Project Management For Healthcare Essay Example | Topics and Well Written Essays - 250 words
Project Management For Healthcare - Essay Example IT risks may involve computer viruses, hacking, phishing or completed system crashes. In healthcare these have very high risk levels as they may result in loss of important electronic records for the organization and patients thus wreaking havoc to the whole system. IT risks may also involve the project information being accessed by others who may want to use it. The financial element of project management can also be a potential risk to healthcare projects; if for some reason the organization does not have enough finances for the project then it may be brought to a complete halt. Liability issues are also common in healthcare involving management of patients and their information and thus project managers must put into consideration. Risks coming directly from the project may include doing something for the first time, changes in crucial requirements, poor estimation of resources and lack of clarity in definition of responsibilities. There may also be external risks in the forms of natural catastrophes, and regulations e.g. on manufacturers of medical instruments and pharmaceutical companies. People risks include lack of proper controls, poor relations, lack of leadership, organizational designs being poor, lack of conflict management programs in place and people lacking proper skills to communicate. In conclusion therefore project management for healthcare is not an easy task; so many events some unexpected may pose risks which may make it very hard to successfully run a project. Risks range from IT, issues, financial resources, the environment, people issues and natural events. It is therefore to anticipate challenges upfront when running with projects and plan some mitigation plans in order to ensure the project is a

The Airbus Way Assignment Example | Topics and Well Written Essays - 2500 words
The Airbus Way - Assignment Example The paper has further disclosed the main reason underlying behind the failure of a merger agreement between the European Aeronautic Defence and Space (EADS) and British Aircraft Marconi Electronic (BAE) system. The national and organizational culture has been recognized to be significantly correlated with each other as both of these cultures impose both positive along with negative impact upon the performance of different organizations. According to the present rapid development of the business environment, the modern organizations intend to focus more upon internationalization process while making different business transactions with the intention of expanding their businesses (Park, 1997). From the perspective of Airbus and its global business operations, the organization considerably tends to emphasize upon promoting its cultural diversity while performing business operations in the foreign countries. The organization maintains several effective workforce diversity-based programmes in excess of 100 nations with 55,000 employees. It has been viewed that the employees of the organization shares information and connects each other from different cultural backgrounds irrespective of age, sex , race, ethnicity as well as experience and abilities. The organization often seeks to acquire mix ideas and knowledge from different people belonging to the diverse culture in order to accomplish superior competitive position over its chief business market contenders (Airbus, 2013). This paper intends to discuss the application of two cross-cultural comparative models to Airbus in order to analyze as well as evaluate the impact of national culture issues on the organizationââ¬â¢s own culture. Various aspects that include the problems of cultural diversity that has created for Airbus and the identification to what extent the cultural differences may have contributed to the recent failure of the planned merger between Airbusââ¬â¢ parent company EADS and BAE Systems.

Everything you need to kow about a computer mouse Essay
Everything you need to kow about a computer mouse - Essay Example Dr. Douglas Carl Engelbart of Stanford Research Institute (SRI) invented the mouse in early 1960s. He worked with Bill English, the man behind the hardware design of the first mouse. Engelbart's innovative ideas changed the way working with computers, from a more complicated to a user-friendly machine. The results of analyzing different characteristics of pointing input devices (such as speed and accuracy) led to the invention of the first prototype computer mouse. Engelbart first called this device as "X-Y Position Indicator for a Display System," wherein it received its patent number 3,541,541 on November 17, 1970. According to an interview, Douglas Engelbart said, "SRI patented it, but they really had no idea of its value. Some years later I learned that they had licensed it to Apple for something like $40,000." So, how did this device get its popular name At first, it had its cord in front, so it was termed "mouse" and that's were it got its smart name. However, they later on changed the cord's position as the present mouse is. In early 1970s, Bill English invented the so-called "ball mouse" while he was working for Xerox Palo Alto Research Center (PARC). In 1981, Xerox Corporation introduced Star, officially known as the 8010 Star Information System, which features various technologies including mouse. Inspired by Xerox Star, Apple Computer released Apple Macintosh in 1984, which made mouse popular and indispensable for computer use. II. TYPES There are three basic types of mouse: mechanical, optomechanical, and optical mouse. Mechanical mouse has a rubber or metal ball at the base that moves against two rollers as it passed across a flat surface. As the ball rolls on a certain direction, circuits in the mouse translate its movement into signals the computer understands. Mechanical mouse must be place on a mouse pad - a rectangular rubber that provides better traction than the top of the desk. Optomechanical mouse works on the same principal as the mechanical mouse but uses optical sensors to detect the motion of the ball. Optical mouse on the contrary, has no moving mechanical parts inside. Instead, it uses light-emitting diodes (LED) to detect the mouse's movement. It is more efficient than mechanical and optomechanical mice but is also more expensive. III. CONNECTIONS A mouse can connect to your computer in several ways. Serial mouse connects directly to RS-232C serial port. Bus mouse connects directly on a small round connector (female mini-DIN-9), but this is pretty well obsolete because this mouse is difficult to install. PS/2 connects to a PS/2 connector (female mini-DIN-6); it's installed as simple as any serial mouse. Cordless mouse uses is a battery-powered device that transmits data using infrared technology of radio waves to communicate with the computer. Some users prefer to use cordless mouse because it frees him from the hassles of cords and provides much desk space. USB mouse is the easiest mouse you can connect in your computer, even when your computer is running. IV. SPEED Mouse speed is expressed in DPI (dots per inch), which is the number of pixels the mouse cursor will move when the mouse is moved one inch. V. INNOVATIONS AND ALTERNATIVE DEVICES a. Trackball is an input device with a ball mounted in its surface, which rotates to control the position of the cursor. b. Touchpad is an input device

Brothel Book Essay Example | Topics and Well Written Essays - 2000 words
Brothel Book - Essay Example A critical analysis of this book shows that Durkheimââ¬â¢s functionalist perspective to deviance as well as Mertonââ¬â¢s social structure and anomie theory can be applied to the groups of characters which include the prostitutes and the men who visit the brothel in the above mentioned book. Emile Durkeim suggests that crime is inevitable and he argues that crime is ââ¬Å"an integral part of all healthy societies,â⬠(as cited in Haralambos & Holborn, 1990, p.586). From this perspective, it can be noted that not all individuals are committed to the shared values and moral beliefs of the society. It may be impossible for all the members of the society to be similar and in Durkeimââ¬â¢s words, crime is not only inevitable, but it is functional. He argues that social change begins with some form of deviance and as noted in the definition of deviance above, deviant behaviour can be normal in other societies. In this given book, it can be seen that prostitution is not conside red as deviant behaviour especially by those involved in this practice. It is seen as normal just like any other form of employment. This view is supported by Cohen who developed Durkeimââ¬â¢s ideas when he analyses two functions of crime in a society. Firstly, deviance can be a safety valve providing a relatively harmless expression of discontent while protecting social order (Haralambos & Holborn, 1990). He suggests that prostitution can perform a safety valve function without threatening the fabric of the family. Prostitutes interviewed in this book state that the majority of their clients are married men who will be seeking to relieve their stress and pressure from the demands of their families. The institution of the family is not threatened in this case since the relationship between prostitutes and clients is not binding. On the other hand, Cohen suggests that certain deviant acts are useful in warning that certain aspects of the society are not functioning. For instance, a lot of married couples reveal that their sexual relationship is not satisfactory, the reason why they seek the services of commercial workers to satisfy their sexual desires. In some cases, unsatisfactory sexual relationships among married couples can lead to divorce and the ladies in most cases opt to venture into prostitution. As is the case in this book, a notable number of prostitutes at Mustang brothel are divorcees as a result of unfriendly sexual relationships in their previous marriages. Men on the other hand will solicit for sex from the prostitutes after the marriage has broken down. It can be seen that the element of prostitution is inevitable as long as these negative social trends affecting the institution of the family persist. The other theory that can be applied to the behaviour of the characters in this book is Mertonââ¬â¢s social structure and anomie. He argues that deviance results from the culture and structure of society itself (Haralambos & Holborn, 1990). Since members are placed in different class positions in the social structure, it can be noted that they do not have the same opportunity of realising the shared values which leads to deviance. In the given case, many prostitutes interviewed by the author such as Eva revealed that they joined the profession in order to earn a living. Some
