One things without a doubt, they absolutely dont hold back on their superstars. Big names have a captivating history that extraordinarily impacts South American residents. The United States has a fundamental influence in their popularity, helping them to turn into the unprecedented individuals that they are today. Models, sports players, entertainers, actresss, and performers are a basic component of the stunning society of South America. About the entirety of the famous people of South America are found in, or begin from, the nation of Brazil. Brazil is South Americas driving nation when it comes to famous people. It contains more than 350 big names that are perceived worldwide for the things that they have accomplished during their life. Insights show that 37% of Brazils working residents work at employments in the expressive arts. Roughly 33% of those individuals are locally remembered, one seventh are broadly perceived, and more are gathering every year. In a meeting with a educational committee in Brazil, we were informed that more than  ¾ of the secondary school understudies are endeavoring to become craftsmen, entertainers/on-screen characters, models, or pro athletics players. Measurements for other South American nations state that less at that point 33% of the understudies state that they would pick these occupations. Measurements likewise show that 97% of Brazilians have gone to a soccer match, show, move execution, or presentation at any rate once in the course of their life. Much the same as South America, the United States rotates around current, and now and then previous, famous people.

Human Resurces - Essay Example As another understudy, I was constantly eager over such real factors however figured out how to permit myself an opportunity to adjust to my new condition. I saw that the laborers who had tutors got acclimated with standard schedules at an a lot quicker rate than the individuals who, such as myself, for some reason didn't. I saw that assistants with tutors were propelled by their mentors’ trust in their capacities and put forth more attempts to find out about their new associations than wrapped up of us. Their tutors additionally put time in training and empowering the understudies, in this manner moving their work aptitudes to the new specialists (Forster 2005). Clearly authoritative goals must be practiced through the aggregate contribution everything being equal, paying little heed to rank. Intelligent and Reflexive Practice In the vast majority of my positions, I was a piece of a group or gathering that was liable for achieving certain targets. I would possess an energy fo r individual reflection during which I considered my job in the gathering work and how to best achieve my duties. After this, I had the option to try the gleanings from individual reflection. I would then communicate my thoughts regarding my rising mindfulness about my job in bunch meetings. In every one of these group meetings, colleagues shared on how they accepted that their commitments would influence the acknowledgment of organization objectives regularly. Subsequent to offering to others about such encounters, the understudies would then come back to actualize the recommendations from the gathering meeting, and afterward mirror once more (Hofstede 2003). As assistants, we as a whole profited by the aggregate practices recommended just as the individual activities taken by us all. My own beliefs really affected how I deciphered corporate choices and arrangements. Now and again my own qualities were at chances with some authoritative sayings. At such time, I would effectively lo ok for the assessments of other who I knew had additionally encountered some proportion of contention during the joining procedure. From them, I discovered this is a flawlessly ordinary event which is looked by practically all understudies during their direction. These ‘older’ laborers likewise helped me to find manners by which I could make organization standards my own or change my own perspectives to suit them. Reflexivity is clear of the procedure whereby a person’s mindfulness is created to where reflection is quickly trailed by a reaction with no time in the center (Guest and Conway 2004). Reflexive workers will make be faced by issues and rapidly discover answers for them with consistency. At the point when such faculty go over strategies that they contradict, they have the indispensable mindfulness to perceive their difference and express it in an understandable way to all (Brooks 2003). This is a quality that I set aside some effort to create during my t emporary job. It just came after I had comprehended the essential elements of organization activities. Also, it was evident to me this was an imperative part for workers to have the option to relate well with associates just as achieve their undertakings (Debra and Quick 2006). Preparing was by all account not the only thing that brought about the reflexive attribute being seen in representatives; every individual worker needed to learn at their own pace. A few analysts have in the past guaranteed that preparation and improvement rehearses in associations should be joined as equivalent

Drinking Alcohol Associated With Obesity

Drinking Alcohol Associated With Obesity Addiction Alcohol Use Print Drinking Alcohol Associated With Obesity By Buddy T facebook twitter Buddy T is an anonymous writer and founding member of the Online Al-Anon Outreach Committee with decades of experience writing about alcoholism.

Learn about our Medical Review Board Steven Gans, MD Updated on September 24, 2019 Peter Dazely/Getty Images More in Addiction Alcohol Use Binge Drinking Withdrawal and Relapse Children of Alcoholics Drunk Driving Addictive Behaviors Drug Use Nicotine Use Coping and Recovery Is drinking alcohol linked to obesity? The answer is it is possible, although research on the association has produced inconsistent results. It may be that its not how often you drink, but how much you drink when you do drink that affects weight gain. Some research suggests that its your pattern of drinking that affects your body mass index (BMI). Body mass index (BMI) is the relationship of someones weight to their height. It is calculated by dividing your weight in kilograms by your height in meters squared. A BMI measurement of 18.5 to 25 indicates normal weight; 25 to 30 is overweight, and over 30 is considered obese. Pattern of Drinking Is a Factor A study of 37,000 drinkers who never smoked tobacco, found that BMI was linked to the number of drinks the subjects had on the days that they did drink. Because previous studies had linked smoking and drinking to weight gain, the NIAAA study looked at only those drinkers who had never smoked. In our study, men and women who drank the smallest quantity of alcoholâ€"one drink per drinking dayâ€"with the greatest frequencyâ€"three to seven days per weekâ€"had the lowest BMIs, said first author Rosalind A. Breslow, Ph.D., while those who infrequently consumed the greatest quantity had the highest BMIs. Contradictory and Inconsistent Results Previous studies have not definitively linked alcohol consumption with weight gain. A systematic review of the literature on the subject found that cohort studies with long periods of follow-up produced contradictory results. Findings from short-term experimental trials also failed to show a clear trend regarding drinking and obesity. Overall, the review found, that research has not established a clear link between alcohol consumption and weight gain. But, studies that did positively link alcohol consumption with weight gain mainly involved higher levels of drinking. Quantity and Frequency Are Factors Breslows study used a different method of assessing alcohol consumption compared to previous studies, she explained. Alcohol consumption consists of two components, explained Dr. Breslow, the amount consumed on drinking days (quantity), and how often drinking days occur (frequency). Previous studies generally examined drinking based only on average volume consumed over time. However, the average volume provides a limited description of alcohol consumption as it does not account for drinking patterns. For example, an average volume of 7 drinks per week could be achieved by consuming 1 drink each day or 7 drinks on a single day. Average volume may not fully explain important relations between quantity and frequency of drinking and health outcomes such as obesity. Heavy Drinking May Stimulate Eating Breslow and her colleagues concluded that there may be several reasons that her study found a link between both quantity and frequency of alcohol consumption to BMI. Alcohol is a significant source of calories, and drinking may stimulate eating, particularly in social settings, said Dr. Breslow. However, calories in liquids may fail to trigger the physiologic mechanism that produces the feeling of fullness. It is possible that, in the long-term, frequent drinkers may compensate for energy derived from alcohol by eating less, but even infrequent alcohol-related overeating could lead to weight gain over time. Type of Alcohol May Be a Factor Other studies have indicated that the type of alcohol consumed may be a factor in whether nor not drinkers experience weight gain. For example, light-to-moderate wine consumption has been found to protect against weight gain, while drinking spirits has been positively associated with weight gain. Additionally, common sense tells us that its called a beer belly for a reason. So, what is the bottom line? Does drinking alcohol cause weight gain or not? Does Drinking Cause Weight Gain? The answer could be yes if you: Drink heavily when you do drinkDrink beer and liquor, instead of wineIf you have a tendency for weight gain to begin with Scientists agree that more studies are needed to determine if drinking patterns increase the risks for weight gain if certain types of alcohol are more likely to cause weight gain and if the persons general tendency to gain weight regardless of their drinking is a factor when they do begin to drink.

Atomic Number 6 - Carbon or C

Carbon the element that is atomic number 6 on the periodic table. This nonmetal is the basis for life as we know it. Its familiar as a pure element, as diamond, graphite, and charcoal. Fast Facts: Atomic Number 6 Element Name: CarbonAtomic Number: 6Element Symbol: CAtomic Weight: 12.011Element Group: Group 14 (Carbon Family)Category: Nonmetal or MetalloidElectron Configuration: [He] 2s2  2p2Phase at STP: SolidOxidation States: Usually 4 or -4, but also 3, 2, 1, 0, -1, -2, -3Discovery: Known to the Egyptians and Sumerians (3750 BCE)Recognized as an Element: Antoine Lavoisier (1789) Element atomic number 6 is carbon. Forms of pure carbon include diamond, graphite, and amorphous carbon. Dave King / Getty Images Element Atomic Number 6 Facts Each atom of carbon has 6 protons and electrons. The element naturally exists as a mix of three isotopes. Most of this carbon has 6 neutrons (carbon-12), plus there are small amounts of carbon-13 and carbon-14. Carbon-12 and carbon-13 are stable. Carbon-14 is used for radioisotope dating of organic material. A total of 15 isotopes of carbon are known.Pure carbon can take any of several different forms, called allotropes. These allotropes exhibit markedly different properties. For example, diamond is the hardest form of any element, while graphite is very soft, and graphene is stronger than steel. Diamond is transparent, while other forms of carbon are opaque gray or black. All of the allotropes of carbon are solids at room temperature and pressure. The discovery of the allotrope fullerene won the Nobel Prize in Chemistry in 1996.The element name carbon comes from the Latin word carbo, which means coal. The element symbol for atomic number 6 is C. Carbon is among the elements known in pure form by ancient mankind. Primitive man used carbon in the forms of soot and charcoal. The Chinese knew of diamonds as early as 2500 BCE. Credit for the discovery of carbon as an element is given to Antoine Lavoisier. In 1772, he burned samples of diamond and charcoal and proved each released the same amount of carbon dioxide per gram.Carbon has the highest melting point of the pure elements at  3500  °C (3773 K, 6332  °F).Carbon is the second most abundant element in humans, by mass (after oxygen). Approximately 20% of the mass of a living organism is atomic number 6.Carbon is the fourth most abundant element in the universe. The element forms in stars via the triple-alpha process in which helium atoms fuse to form atomic number 4 (beryllium), which then fuses with atomic number 2 (helium) to form atomic number 6.Carbon on Earth is constantly recycled via the Carbon Cycle. All of the carbon in your body once existed as carbon dioxide in the atmosphere.Pure carbon is cons idered non-toxic, although inhaling it can cause lung damage. Carbon particles in the lung may irritate and abrade lung tissue, potentially leading to lung disease. Because the carbon particles resist chemical attack, they tend to remain in the body (except the digestive system) indefinitely. Pure carbon, in the forms of charcoal or graphite, may be safely ingested. It has been used since prehistoric time for making tattoos. The tattoos of Otzi the Iceman, a 5300-year-old frozen corpse, were likely made using charcoal.Carbon is the basis for the organic chemistry. Living organisms contain four classes of organic molecules: nucleic acids, fats, carbohydrates, and proteins.The reason element atomic number 6 is so important for life is because of its electron configuration. It has four valence electrons, but the p-shell is most stable when it is full (octet) or empty, giving carbon a usual valence of 4 or -4. With four binding sites and a relatively small atomic size, carbon can form c hemical bonds with a wide variety of other atoms or functional groups. Its a natural pattern maker, able to form polymers and complex molecules.While pure carbon is non-toxic, some of its compounds are lethal poisons. These include ricin and tetrodotoxin.In 1961, the IUPAC adopted the isotope carbon-12 as the basis for the atomic weight system. Sources Greenwood, Norman N.; Earnshaw, Alan (1997).

How Does The Control Of Production Mean For The Media...

How does â€Å"the space of possibilities† (Bourdieu 1983) both theoretically and physically, define the media, medium, and message that is produced within it? What does the act of production mean for the media produced? Media, through technology and its use by agents in social and material production, operates on a local and a global level through its production and dissemination. This creates spaces in which roles and agendas can be played out to the conclusion of an end product. This end product, however, is not only the produced media, but the anticipated reception of the consumer and the after-effects of the content specifically targeted by the producers or more generally as a consumable thing by a wider audience. Whether we talk about the local or the global, something that shouldn’t be discounted is the cultural accumulation and dispersion that takes place in both spaces in practice. Hannerz writes, â€Å"culture is learned and acquired in social life† (Hannerz 1998: 8), â€Å"it is somehow integrated† (ibid), and â€Å"these collectivities† (ibid), are â€Å"affected by interconnectedness in space† (ibid). The third point is the most important when we tal k about the global, as the global has become created and defined by the interconnectedness it inevitably generates. This essay will examine the ‘spaces’ within media production, which facilitate and constrain that production, especially â€Å"the space of possibilities† (Bourdieu 1983), or as Foucault named it the â€Å"field of strategicShow MoreRelatedLegal And Ethical Issues Of The Media1430 Words   |  6 PagesThe media is a large, diverse means of mass communication.

The contents of this report prove that Media has been major player in the promotion of IT. The report is based on our observations, technical know how and various sources which have been mentioned at the end of this report. Humanity has progressed from agricultural revolution to the industrial revolution and is now moving to an information revolution, where knowledge is the prime resource for production of goods and services. Just as machines have extended man’s mechanical power and his convenience and comfort. The invention of printing was the first big break-through in Information Technology. It enabled literacy and education to go up from 10% to over 80% within 50 years by making available vast amount of reading material. That reading also led to the Reformation in Europe. Other break-through for Information Technology were the inventions like telegraphy, telephony, wireless or radio, television, broadcasting, computers (from room size to desk top to lap top to palm top and very soon, wearable ones. ) Information Technology as commonly picturised by computers, is extending man’s mind or brain or intellectual power. Information Technology devices like microprocessors are becoming mass appliances from pace makers for the heart, hearing aids, and efficiency enhancers in automobile engines and devices to steer space vehicles on the moon. The computing power in the few micro processors that are now in a Ford Motor Car is much more than all the computing power that was put in the space vehicle that landed the first men on the moon and brought them back. I hope the report will be self explanatory, if not or you have any ambiguity, please contact us huzefanajeeb@gmail. om Sincerely Hozefa Rasool Ather Khan INTRODUCTION TO INFORMATION TECHNOLOGY Information technology (IT), as defined by the Information Technology Association of America (ITAA), is â€Å"the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. † In short, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit and retrieve information, securely. Recently it has become popular to broaden the term to explicitly include the field of electronic communication so that people tend to use the abbreviation ICT (Information and Communications Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term is more recognizable than ever before. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include: Data management Computer networking Computer engineering Database systems design Software design Management information systems Systems management or System administration The use of information technology is penetrating a still wider part of human life, linking areas of human life and making different media and technologies converge and dissolve into new ones, broadening the scope of interest for ISD research accordingly. Various academic disciplines deal with issues related to the use and development of information technology: information systems research, human-computer interaction, computer supported collaborative work, theoretical computer science etc. As these disciplines are getting more and more intertwined and interdependent the need for an integrating conceptual basis is becoming urgent. The hypothesis behind the present collection of papers is that activity theory is such a suitable theoretical basis. Ultimately, information technology is about some familiar ideas: Improved access to information Increased staff productivity Lower operations costs APPLICATIONS OF INFORMATION TECHNOLOGY Because new technologies such as personal computers are complex and an element of uncertainty exists in the minds of decision makers with respect to the successful adoption of them, people form attitudes and intentions toward trying to learn to use the new technology prior to initiating efforts directed at using. Attitudes towards usage and intentions to use may be ill-formed or lacking in conviction or else may occur only after preliminary strivings to learn to use the technology evolve. Thus, actual usage may not be a direct or immediate consequence of such attitudes and intentions. (Bagozzi et al. 1992) PC Revolution is now well into its third decade and the continuing improvements in the user friendliness of PCs and Macs, printers and scanners, and software and the Internet has been enormous. The major application areas of Information Technology are briefly described. Data Management Data management comprises all the disciplines related to managing data as a valuable resource. The official definition provided by DAMA is that â€Å"Data Resource Management is the development and execution of architectures, policies, practices and procedures that properly manage the full data lifecycle needs of an enterprise. † This definition is fairly broad and encompasses a number of professions which may not have direct technical contact with lower-level aspects of data management, such as relational database management. Computer Networking Computer networking is the engineering discipline concerned with communication between computer systems or devices. Communicating computer systems constitute a computer network and these networks generally involve at least two devices capable of being networked with at least one usually being a computer. You read "Media Supporting Information Technology" in category "Papers" The devices can be separated by a few meters (e. g. via Bluetooth) or nearly unlimited distances (e. g. via the Internet). Computer networking is sometimes considered a sub-discipline of telecommunication, and sometimes of computer science, information technology and computer engineering. Computer networks rely heavily upon the theoretical and practical application of these scientific and engineering disciplines. Examples of networks are the Internet, or a small home local area network (LAN) with two computers connected with standard networking cables connecting to a network interface card in each computer. Data Base Management System The Data Base Management System accepts requests for data from the application program and instructs the operating system to transfer the appropriate data. When a DBMS is used, information systems can be changed much more easily as the organization’s information requirements change. New categories of data can be added to the database without disruption to the existing system. Organizations may use one kind of DBMS for daily transaction processing and then move the detail onto another computer that uses another DBMS better suited for random inquiries and analysis. Overall systems design decisions are performed by data administrators and systems analysts. Detailed database design is performed by database administrators. Computer Software Computer Software of programs, enables a computer to perform specific tasks, as opposed to its physical components (hardware) which can only do the tasks they are mechanically designed for. The term includes application software such as word processors which perform productive tasks for users, system software such as operating systems, which interface with hardware to run the necessary services for user-interfaces and applications, and middleware which controls and co-ordinates distributed systems. Management Information System Management Information Systems (MIS) is a general name for the academic discipline covering the application of people, technologies, and procedures. Collectively called information systems, to solve business problems. MIS are distinct from regular information systems in that they are used to analyze other information systems applied in operational activities in the organization. Academically, the term is commonly used to refer to the group of information management methods tied to the automation or support of human decision making, e. g. Decision Support Systems, Expert systems, and Executive information systems. Computer Simmulation A computer simulation, a computer model or a computational model is a computer program that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modelling of many natural systems in physics, chemistry and biology, human systems in economics, psychology, and social science and in the process of engineering new technology, to gain insight into the operation of those systems. Traditionally, the formal modeling of systems has been via a mathematical model, which attempts to find analytical solutions to problems which enables the prediction of the behaviour of the system from a set of parameters and initial conditions. Computer simulations build on, and are a useful adjunct to purely mathematical models in science, technology and entertainment.

II. The Third Generation (1964-1979): Advanced programming languages like BASIC developed. III. The Fourth Generation (1979- Present). INTRODUCTION TO MEDIA †Materials that holds and transmit data in any form including Newspapers, Multimedia Presentations, Disk Drives, Optical disks, Magnetic Tape, Cable and many more. In other definition Media is defined as, â€Å"Messages that are distributed through the technologies, principally text in books, study guides and computer networks; sound in audio-tapes and broadcast: pictures in video-tapes and broadcast; text, sound and/or pictures in a teleconference are termed under Media. † There are three main types of media: Print Electronic Published FORMS APPLICATIONS OF MEDIA Journalism Journalism is a discipline of collecting, analyzing, verifying, and presenting information regarding current events, trends, issues and people. Those who practice journalism are known as journalists. News-oriented journalism is sometimes described as the â€Å"first rough draft of history† (attributed to Phil Graham), because journalists often record important events, producing news articles on short deadlines. While under pressure to be first with their stories, news media organizations usually edit and proofread their reports prior to publication, adhering to each organization’s standards of accuracy, quality and style. Many news organizations claim proud traditions of holding government officials and institutions accountable to the public, while media critics have raised questions about holding the press itself accountable. Broadcasting Broadcasting is the distribution of audio or video signals to a number of recipients (â€Å"listeners† or â€Å"viewers†) that belong to a large group. This group may be the public in general, or a relatively large audience within the public. Thus, an Internet channel may distribute text or music worldwide, while a public address system in; for example, a workplace may broadcast very limited ad hoc SoundBits to a small population within its range. The sequencing of content in a broadcast is called a schedule. Internet The Internet (also known simply as â€Å"the Net† or â€Å"the Web†) can be briefly understood as â€Å"a network of networks†. Specifically, it is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It consists of millions of smaller domestic, academic, business, and governmental networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web. Advertising Advertising is paid, one-way communication through a medium in which the sponsor is identified and the message is controlled. Variations include publicity, public relations, product placement, sponsorship, underwriting, and sales promotion. Every major medium is used to deliver these messages, including: television, radio, movies, magazines, newspapers, the Internet and billboards. Advertisements can also be seen on the seats of grocery carts, on the walls of an airport walkway, on the sides of buses, heard in telephone hold messages and in-store public address systems. Advertisements are usually placed anywhere an audience can easily and/or frequently access visuals and/or audio. MEDIA PROMOTING INFORMATION TECHNOLOGY Just as chemical or metallurgical or electrical technologies enable the processing of raw materials into usable goods, to satisfy man’s and societies’ needs so does information technology help the storage, processing, transmission and exploitation of information to satisfy a person’s, company’s, society’s or government’s needs for information. The invention of printing was the first big break-through in Information Technology. It enabled literacy and education to go up from 10% to over 80% within 50 years by making available vast amount of reading material. That reading also led to the Reformation in Europe. Other break-through for Information Technology were the inventions like telegraphy, telephony, wireless or radio, television, broadcasting, computers (from room size to desk top to lap top to palm top) BROADCASTING REVOLUTION Digital audio and digital video have revolutionized broadcast engineering in many respects. Broadcast studios and control rooms are now already digital in large part, using non-linear editing and digital signal processing for what used to take a great deal of time or money, if it was even possible at all. Mixing consoles for both audio and video are continuing to become more digital in the 21st Century, as is the computer storage used to keep digital media libraries. Effects processing and TV graphics can now be done much more easily and professionally as well. Other devices used in broadcast engineering are telephone hybrids, broadcast delays, and dead air alarms. See the glossary of broadcast engineering terms for further explanations. PRINTING AS STRONGER MEDIA Within fifty or sixty years of the invention of the printing press, the entire classical canon had been reprinted and widely promulgated throughout Europe. Now that more people had access to knowledge both new and old, more people could discuss these works. Furthermore, now that book production was a more commercial enterprise, the first copyright laws were passed to protect what we now would call intellectual property rights. A second outgrowth of this popularization of knowledge was the decline of Latin as the language of most published works, to be replaced by the vernacular language of each area, increasing the variety of published works. Paradoxically, the printing word also helped to unify and standardize the spelling and syntax of these vernaculars, in effect ‘decreasing’ their variability. This rise in importance of national languages as opposed to pan-European Latin is cited as one of the causes of the rise of nationalism in Europe. VIRTUAL UNIVERSITY The Virtual University is based completely on modern Information and Communication Technologies. It provides extremely affordable world class education to aspiring students all over the country. Using free-to-air satellite television broadcasts and the Internet, the Virtual University allows students to follow its rigorous programs regardless of their physical locations. It thus aims at alleviating the lack of capacity in the existing universities while simultaneously tackling the acute shortage of qualified professors in the country. By identifying the  top Professors of the country, regardless of their institutional affiliations, and requesting them to develop and deliver hand-crafted courses, the Virtual University aims at providing the very best courses to not only its own students but also to students of all universities worldwide. EFFICIENT MEDIA REPORTING As newspapers, magazines, trade publications and newsletters creep on to the Web; this swells the demand for reporters, who can keystroke simple sentences and strings of numbers. New media positions do not increase the job market for journalists. For this purpose, reporting is defined as nuts-and-bolts, no-nonsense information-gathering and packaging. Reporting wants just the facts. Journalism entails investigation, explanation and a point of view. Journalists are story-tellers, fascinated with the human experience, alert to the drama of conflict and struggle, infinitely curious about the motives and meanings behind events. Reporters use nouns and verbs as blunt utilitarian instruments. Journalists indulge in figures of speech; they use words as symbols, to evoke empathy, indignation, pity or anger. Most of what appears in Star or the National Enquirer is journalism, albeit of a very ripe kind. Most of Investor’s Business Daily is reporting. ELECTRONIC NEWSPAPER In the late 1990’s newspapers began offering their content on the Internet in record numbers. By the end of the decade, more than 1,000 North American newspapers offered online versions, most available to Internet users free of charge. Electronic newspapers spared publishers one of their highest expenses—newsprint—and many brought publishers additional advertising revenue. Today Newspapers on the web offers readers the same content as its print publication as well as stories and features available only in its online version. ANALYSIS OF INFRA-STRUCTURE The government firmly believes in bringing the Pakistani media at par with the international standards and a total of 52 media development projects are being launched in the year 2007-08 with record allocation of six billion rupees, according to Federal Minister for Information and Broadcasting Muhammad Ali Durrani. Rs. 148. 039 million has been earmarked for the media development projects in NWFP, which demonstrates the government’s firm resolves to take all the federating units along in the development process. The Laram Top RBS has been established at the cost of Rs. 27. 97 million and is designed to serve around 450,000 people, while the RBS at Bajaur Agency, established with the total cost of 34. 733 million, is expected to cover 75,000 households, he said. The projects will not only carry the benefits of the modern age to distant regions of the country but will also bring affordable entertainment at the doorsteps for the common public. Islamabad Media University will be launched in the federal capital within next two months at a cost of Rs. 500 million, followed by setting up of its provincial campuses, including the Peshawar campus, in the second phase. Media University will not only offer specialized courses in media and journalism but will also initiate various research projects on media related issues. Rs. 35. 55 million will be spent to ensure full FM Radio coverage on Motorways sections M-1 which links Peshawar with Islamabad, and M-2, connecting Islamabad to Lahore. FM facility on the motorways will not only make the 500 KM-long journey from Peshawar to Lahore informative and pleasant but will also provide better opportunities to the media sector to expand itself in those gaps which are desperately needed to be filled in. Beside s this, up-linking stations will also be established in Islamabad as well as in all the provincial capitals, including Peshawar, which will cost around 49. 81 million rupees. These up-linking facilities would provide efficient and high quality information flow between the network and the subscriber.

Manhattan Project Essays (1818 words) - , Term Papers

Manhattan Project Manhattan Project In the early morning hours of July 16, 1945, the first ever nuclear explosion took place in Alamogordo, New Mexico. The explosion was the first test of the most destructive weapon ever known to man, and was the result of almost six years of research and development by some of the world's top scientists. This endeavor was known as the Manhattan Project. Less than a month after the test, which was known as Trinity, the United States dropped two nuclear bombs on Japan, three days apart, which forced the Japanese to surrender. The story of the Manhattan Project is an abysmal subject, as is the effect of the Manhattan Project on international politics, and both will be covered in this paper. Indeed, the Manhattan Project and the creation of the atomic bomb were good things, because it actually decreased the likelihood of nuclear war in the post- World War II era. The Manhattan Project was preceded by a variety of scientific discoveries in the 1920's and the 1930's. During this time of scientific discovery, Hitler had been steadily rising to power in Germany, and before long, physicist Leo Szilard and fellow Hungarian Jews Eugene Wigner and Edward Teller became worried. They decided that the President of the United States must be informed about the new fission technology that had been discovered, which they believed was capable of making bombs. The three physicists enlisted the help of Albert Einstein, the foremost scientist in that period, and together they drafted a letter addressed to President Roosevelt describing their beliefs that nuclear fission "Would...lead to the construction of bombs, and it is conceivable...that extremely powerful bombs of a new type may thus be constructed." At first, not much money or interest was spent on the atomic bomb program. However, the combination of France's fall to Germany in 1940, the belief that Germany was ahead in the race for the atomic bomb, and the bombing of Pearl Harbor soon convinced Roosevelt that something more had to be done on this atomic research. Roosevelt quickly assigned his top security advisors to form committees on this project, and to determine what should be done and how. By the end of 1942, bomb research had become bomb production, and the Manhattan Project was now run by the military, with Colonel (soon to be General) Leslie R. Groves as the officer in charge. Bomb production was carried out in three locations; Oak Ridge, Tennessee handled the production of the bomb fuel U-235, Hanford , Washington handled the production of plutonium fuel, and Los Alamos, New Mexico handled bomb production and assembly. These three locations became huge cities due to the size of and manpower required for this project. "About half of [the American Physical Society's 4000 members] joined the Manhattan Project, which at its height employed roughly 10,000 scientists with advanced degrees." Eventually, fuel production began meeting the needs of Los Alamos, and by 1945, the bombs themselves were in production. On April 12, 1945, President Roosevelt died, and Harry Truman took over. Secretary of War Henry Stimson took the primary role of filling in President Truman on the details of the Manhattan Project, which Truman had known nothing about. In July of 1945, President Truman met with Winston Churchill of Britain and Joseph Stalin of the Soviet Union at the Potsdam conference, at which time the "Big Three" drafted the Potsdam Declaration, which offered the Japanese the opportunity to unconditionally surrender, or "Risk the alternative of 'prompt and utter destruction.'" Japan declined the Potsdam Declaration, and President Truman was left to consider his options. President Truman made the decision to use this nuclear capability, and on August 6, 1945, Lt. Col. Paul W. Tibbets flew the B-29 bomber Enola Gay over Hiroshima, Japan and dropped the first atomic bomb, named "Little Boy." Due to the lack of Japanese surrender, three days later Maj. Charles W. Sweeney flew Bock's Car toward Kokura, Japan, but was detoured by bad weather. Sweeney then flew over the alternate target of Nagasaki and dropped the second atomic bomb, "Fat Man." A few days after the second bombing, Japan accepted the terms of the Potsdam Declaration and surrendered. World War II was over. The effects of the Manhattan project were enormous on all levels- individual, domestic, and international. On the individual level, the lives of the thousands of people involved in the Manhattan Project were forever changed. Robert Oppenheimer, the civilian director of the Manhattan Project and the one whom many credit with the Manhattan Project's success, was stripped of his security clearance during the McCarthy era because of suspected communist

Hippopatamus Essays - British Poetry, Night, Drunken Haze

Hippopatamus Essays - British Poetry, Night, Drunken Haze Hippopatamus The first stanza introduces the scene and tone of the poem. We are given the time as ?Twelve o?clock?, ie. midnight, which is in a sense the witching hours of the day. The walk the narrator embarks on is dramatised in the next few lines as the street is described as ?Held under a lunar synthesis whispering lunar incantations.? This personification of the moon suggests that the moon is possibly acting like a witch casting a spell on the street, allowing the narrator to abolish all rational thoughts and enter an almost dream-like sequence in which a series of irrational thoughts and memories arise. The first mentioning of a ?street lamp? introduces many different ideas. To begin with, the time of the day is midnight, the darkest time of the day. This sets the tone to a rather bleak and dark view of life but the street lamp acts as small patches of light in the street suggesting hope. These small patches of light are also a catalyst for a sequence of thoughts, memories and images that w e are presented with throughout the entire poem. Thus in a way, the street lamp forms a significant motif as it represents hope while stimulates all the thoughts the narrator conjures up. The line ?Beats like a fatalistic drum? gives us the first insight that the narrator may be in a drunken haze causing a possible headache, which explains all the hallucinations though this is never confirmed. The last lines of the first stanza introduces the sense of pandemonium that we should expect throughout the rest of the poem as Eliot compares the narrator?s state of mind with how ?a madman shakes a dead germanium.? A germanium is a flower that is adept at survival yet the fact that it is dead further emphasises the chaotic state of the narrator?s mind. The technique of juxtaposition is used here since on the one hand, Eliot illustrates an external and rational landscape of a street while on the other hand; an internal and irrational landscape of chaotic thoughts is suggested. The second stanza takes the time to one and a half hours later. The repetition of the word ?street-lamp? brings us back to the motif of a catalyst for thoughts. Onomatopoeia and rhyme is used here with ?sputtered?muttered.? This creates a rhythm of walking that reminds us that the narrator is still walking down a street. The street-lamp is also personificated to speak as it evokes the first of a series of thoughts. For the first time in the poem, another person is mentioned, a woman in fact. However, even though the sense of isolation and loneliness is broken, this woman is suggested to be seductive giving us an idea that the narrator has had bad experiences with women and relationships in the past. This is further exemplified in the last line words like ?Twists? and ?crooked pin? which create a sense of emptiness and agony. The third stanza depicts another thought or memory, this time with two very desperate and pessimistic images of life. The first one is of a ?twisted branch? that is eaten up and is compared to the world giving up ?the secret of its skeleton.? This suggests that life simply causes pain and wears people down. The repetitive use of the word twisted evokes pain upon the reader and the fact that the world?s skeleton is ?Stiff and white? implies that the world has no goodness and that there is no miracle of ?magic? involved. .The second image we are given is the ?broken spring in a factory yard.? This metaphor denotes people?s lives as broken and pushed to the limit. It portrays the vulnerability of humanity as the broken spring is only hanging on by rust. This reference to rust shows the corrosive nature of life and brings us back to how life wears us down. The last words ?ready to snap? is very striking as it further shows the fragile nature of life and suggests that humanity is on the v erge of breaking. The next stanza takes us forward once more in time, as it is now half-past two. This time we are given three desperate images that further demonstrate Eliot?s

Converting Centimeters to Meters (cm to m)

Converting Centimeters to Meters (cm to m) Centimeters (cm) and meters (m) are both common units of length or distance. This example problem demonstrates how to convert centimeters to meters using a conversion factor. Converting Centimeters to Meters Problem Express 3,124 centimeters in meters. Start with the conversion factor: 1 meter 100 centimetersSet up the conversion so the desired unit will be canceled out. In this case, we want m to be the remaining unit. distance in m (distance in cm) x (1 m/100 cm)distance in m (3124/100) mdistance in m 31.24 m Answer: 3124 centimeters is 31.24 meters. Converting Meters to Centimeters Example The conversion factor may also be used to convert meters to centimeters (m to cm). Another conversion factor could be used, too: 1 cm 0.01 m It doesnt matter which conversion factor you use as long as the unwanted unit cancels out, leaving the one you want. How many centimeters long is a 0.52 meter block? cm m x (100 cm/1 m) so that the meter unit cancels out cm 0.52 m x 100 cm / 1 m Answer: The 0.52 m block is 52 cm in length.

Criminal Justice Coursework Example | Topics and Well Written Essays - 250 words - 2

Criminal Justice - Coursework Example The social control is often maintained in the criminal justice system to pave the way for orderly and crime free societies. Criminal justice agency mandated by the United States government to exhibit criminal justice is the U.S. department of justice (DOJ’s). This department ensures that all the societal norms are followed to the later. In cases of anomie or normlessness, the criminal law pursuit always takes its course to ensure order is fully restored in all systems in the society. Justice concept of the criminal justice system provides for freedoms and rights of the criminals (Schmalleger 46). Detention before trial is against the criminal justice laws. Taking more days before trial as well is against this law’s pursuit. Lastly, all the criminals are always innocent until proved guilty by the DOJ’s agencies. In summary, the criminal justice system is one of the key role players in a society’s cohesion and integration. The United States criminal justice system is indiscriminative thus exercises enacted laws equally to all the races in the society. The criminal justice ensures there is a universal application of jurisdiction in all the intended societal criminal activities. Through criminal justice, the societies live harmoniously as normless behaviours are highly regulated. These, therefore, are some of the important roles played by criminal justice systems in the United

Personal Skills and Self Management Essay Example | Topics and Well Written Essays - 750 words

Personal Skills and Self Management - Essay Example Having started my career at the ANZ Banking Group about 14 years ago as an operator of Grade 2, I have progressed in my field and am now serving in the ANZ as Level 3 Supervisor within the Loan Operation Department. I hope to progress further and become the Operation State Manager in ANZ and get placed in Category C. The Operation State Manager manages two teams in the Institutional Loan Division. This includes 13 workers and 5 business units. The fact that the Operation State Manager has to take care of the business units in addition to the workers increases and complicates his duties manifolds. He is also expected to achieve the goals of higher management and meet stakeholder expectations. Duties of the Operation State Manager can be fundamentally classified into the four universally known functions of management namely planning, organizing, leading and controlling. One of the most important skills required of a Operation State Manager is communication because he has to interact wi th hundreds of people on daily basis. The word of Operation State Manager means a lot to them. ... If I am to become the Operation State Manager later in my career, it is imperative that I concentrate on improving my communication skills. For that, I would need to gain a good understanding of different styles of communication for use in different kinds of situations. There are four basic styles of communication namely assertive, aggressive, passive, and passive-aggressive. A manager has to see which style fits a particular situation. I also have to analyze the barriers to effective communication. Nevertheless, the manager needs to be more assertive in his communication because it promotes understanding and diffuses anger. ANZ defines leadership characteristics as supportive for the organizational culture. Hence, in order to be a successful manager In ANZ, I would need to conduct thorough analysis of the organizational culture, aims and objectives and accord my leadership qualities with them. The Operation State Manager at ANZ is necessarily a role model for the subordinates and th ey acquire motivation for him. Therefore, I would need to learn how to motivate employees. I would need to conduct a detailed literature review to identify the factors that serve as the biggest source of motivation for the workforce. Such factors include but may not be limited to money, promotion, paid leave and added privileges. It is important for me to optimize my own leadership skills instead of trying to copy other leaders because I believe that effective leadership originates in original personality rather than an artificial one. I expect myself to be ready for this position in the next 3-5 years. Communication and conflict resolution are two of the most fundamental aspects of my current capabilities

Signs That My Site Hacked Information Technology Essay

Signs That My Site Hacked Information Technology Essay Assume you are the owner of an e-commerce web site. What are some of the signs that your site has been hacked. Discuss the major type of attacks you could expect and resulting damage on your site. Prepare a brief report based on your findings. You are required to propose web site development to one of the IT entrepreneurs in your area. Consider there are two opinions for building the site in-house with existing staff, out sourcing the entire operation. Discuss which options are in the companys best interest and the reason for choosing that opinion. Provide pros and cons for each option. Prepare a report based on your findings. Introduction to Question (1) Hacking used to be defined as One who is proficient at using or programming a computer; a computer buff. However, this use has been turned around now, to mean that of a cracker One who uses programming skills to gain illegal access to a computer network or file. This information is about this second meaning, cracking. Before we begin I would like to point out that hackers HATE crackers, crackers have given them a bad name. The main differences between the two are that hackers try to make things, crackers try to break things. Hackers made the Internet what it is today. Hackers program websites (among other things) and they do not try and harm the work of others as is thought in todays society. However, as the word hacker is now in such popular use that it is thought it means cracker I will use the words hacking and cracking for describing these cracking methods. Define question (1) Hacking is not a simple operation or sequence of commands as many people think. Hacking is a skill. To hack you must change and adapt your approach depending on the obstacles you come across. Hacking is not a specific term; there are many types of hacking. Answer for Question (1) Some of the signs that my site has been hacked: One of the goals for a hacker is to hack a website without alerting the website owner. Months go by, and a website owner hosts a hacked website without knowing the site has been compromised. The website owner may notice some strange occurrences, but here are some hacked signs that alert the owner of a compromised website. Websites that are hacked can spread malware, and the hacker sometimes steals your customers information. The Eval Base64_decode Function at the Bottom of Your Code The Eval function is used to hide code in PHP blogs such as Blogger and WordPress. The base64_decode decodes encoded text that you are unable to read when you view your website code files. The hacker places a redirection code using eval and base64_decode at the bottom of your PHP file, so you are unable to read the hacked code and dont notice the redirection to the hackers web page. If you did not put the functions on your page, then your blog or website has probably been hacked. Drop in Google Search Engine Results Rank If my site is hacked with a redirection to an online pharmacy, the Google algorithm detects a problem and lowers your search engine rank. If you check your rank often, you notice a drop in rank. You can drop several pages and even hundreds of pages in the search engine results. A Red Warning Alert in Google Chrome or Firefox When Google detects a hacked website, Firefox and Chrome use the Google API to show a warning message to users. Instead of seeing your website, the web browser shows a red screen alerting the reader to a hacked website address. Users can hit the back button or proceed to my site. In most cases, the user prefers to click the back button to avoid infecting the computer. The best way to detect a hacked website is enter your domain name into Chrome or Firefox and see if the red warning screen shows. Google Indexes Your Site with Pharmacy Text If your site has been hacked and redirects to a pharmacy, search your domain name with pharmacy text such as Viagra, pharmacy, or meds. Pornographic search phrases are also used to check if your site has been hacked and redirect to adult websites. This type of check gives you a heads up, and lets you know the hackers code is somewhere in your website code. Check the .htaccess File on Your Host Server The .htaccess file is a part of an Apache server host. One web hack is placing a redirect code in the .htaccess file. Open the .htaccess file located on the root of your web host directory. Read through the file and locate any odd website addresses. If you have a website address that is not yours in the .htaccess file, your file has been hacked. These tips help you identify a hacked website. After I fix the hack, I must identify where my site vulnerability is is located. If I do not identify the security hole, you are susceptible to hacks after you go through the trouble of fixing hacked code. The type of attacks I could expect and the damages Password cracking In most of the cases, user passwords are encrypted to protect the privacy of passwords and maintain security of the system. Password cracking is the process of decrypting encrypted passwords. A program that performs cracking is known as password cracker. Some crackers are also capable of disabling password protection system and may cause free access to anyone and the owner will be losing a lot of information in his web site. Ip spoofing IP spoofing is used to commit criminal activity online and to breach network security. Hackers use IP spoofing so they do not get caught spamming and to perpetrate denial of service attacks. These are attacks that involve massive amounts of information being sent to computers over a network in an effort to crash the entire network. The hacker does not get caught because the origin of the messages cannot be determined due to the bogus IP address. IP spoofing is also used by hackers to breach network security measures by using a bogus IP address that mirrors one of the addresses on the network. This eliminates the need for the hacker to provide a user name and password to log onto the network. Hijacking an Authorized Session With the ability to generate the correct sequence numbers, an attacker can take over an authorized session by simply taking over one of the parties to the session. Having inserted himself in the session, the attacker will simply tell the party taken over that the session has ended, while connecting to the other half of the legitimate session and continuing communication, but this time, according to the attackers dictate. Haven taken over a trusted communication channel, the attacker can then probe the network for vulnerabilities. Sequesnce Guessing Every connection between two hosts using TCP contain sequence numbers for both data and acknowledgement. These numbers, used by the TCP protocol to determine out-of-order and lost packets, is one of the facilities of the connection-oriented TCP design, to ensure reliable delivery to the application layer. The sequence numbers are generated pseudo-randomly and an attacker might send spoofed packets to a victim to determine the algorithm generating the sequence numbers, and then use that knowledge to intercept an existing session. RIP Attacks Routing Information Protocol (RIP) Routing attacks is often seen in routers which implemented the original RIP. Routing Information Protocol (RIP) is used to distribute routing information within networks, such as shortest-paths, and advertising routes out from the local network. The original version of RIP has no built in authentication, and the information provided in a RIP packet is often used without verifying it. An attacker could forge a RIP packet, claiming his host X has the fastest path out of the network. All packets sent out from that network would then be routed through X, where they could be modified or examined. An attacker could also use RIP to effectively impersonate any host, by causing all traffic sent to that host to be sent to the attackers machine instead. Buffer Overflows A Buffer Overflow is a flaw that occurs when more data is written to a block of memory, or buffer, than the buffer is allocated to hold. Exploiting a buffer overflow allows an attacker to modify portions of the target process address space. This ability can be used for a number of purposes, including the following: Control the process execution Crash the process Modify internal variables   The attackers goal is almost always to control the target process execution. This is accomplished by identifying a function pointer in memory that can be modified, directly or indirectly, using the overflow. When such a pointer is used by the program to direct program execution through a jump or call instruction, the attacker-supplied instruction location will be used, thereby allowing the attacker to control the process.  In many cases, the function pointer is modified to reference a location where the attacker has placed assembled machine-specific instructions. These instructions are commonly referred to as shellcode, in reference to the fact that attackers often wish to spawn a command-line environment, or shell, in the context of the running process . Conclusion If I cannot connect to my web site or log in to your control panel, I have to contact your web hosting company. The hacker attack has changed your password and I need to get a new one. The hacker might have also changed your email address associated with my account at the web hosting company but this is unlikely because the password and the email information are generally segregated. Anyway, depending on the company policies, a web hosting firm would either send you a new password over email OR revert with what they need to send you a new password (because they need to verify that the new password request is legitimate). In some cases, I might need to send a fax because the hackers have messed up your email too. Introduction to Question (2) Nowadays, it seems like everyone is saying, I want to site. If you want to build a web site and you know what you want, dont know what you want, trying to learn about it then we have information for you. If you already own a website or a webmaster looking for the best and latest information on successful website development, then we have the website builder for you. Also on this site we have articles and free eBooks on every aspect of website development, including internet marketing, home based businesses and affiliate marketing. Define question (2) There are many different routes a web site owner can go for getting all of the content done for his online business. The two directions he could take, whether its hiring in-house or outsourcing to a content creation company, allow for many different options and different ways to get your content project done. The route you take can have effect on a number of things, like quality of the content, your expenses, and the time it will take to get everything done. Since the content will probably be the most important part of your web site, you will want to take all things into consideration before making your final decision. Answer to Question (2) IN-HOUSE WITH EXISTING STAFF Hiring in-house definitely has its own advantages. This is because anytime you have a valuable resource like a team of writers in the Internet industry you are able to accomplish many different things because there are so many ways that you can use content on the Internet (it doesnt always just have to be on-site content). It all really depends on your own companys content needs however. You will be able to train writers and mold their styles to the way you want your content to be written. ADVANTAGES: Gives you Control If design services are part of your business, then keeping it under your control allows you to provide the best services for your customers. This means that if your business sells design services, or depends on a strong, dynamic online presence for the bulk of its revenue, an in-house design team is essential. You dont want to rely on a contractor over whom you do not have complete control to make or break your business. Communicate Better and Save Time Interacting with outsourced talent can be challenging, especially if your contractor is . People under your purview are easier to find and easier to direct, so when you need something done, you can explain it to them in person. Save (lots of) Money You will find that you will save money in the long run by using in-house talent. Even though you will have to make the investment in payroll and infrastructure, over time you get better results and spend less money than you would by hiring an outside firm. In-house design also benefits from the standpoint of project cost. Contractors often will pocket some or all of the difference if they finish a project below cost. If your In-house team completes the project at less cost, that cost savings shows up in your bottom line. DISADVANTAGES Maintenance contract with an external agency Although probably the most expensive approach, maintenance contract with an external agency does provide the best level of service. If the agency provide the right kind of service this can be very much like working with an outsource team. The agency will really get to understand the business, evolve your website on a regular basis and still provide all of the benefits of an external agency. Part time contractors For smaller organizations that cannot afford fulltime in-house staff but who wish to enjoy the benefits that come with that approach, there is the option to take on a part-time contractor. These individuals will probably have 2 or 3 websites they manage on a regular basis but still will be able to work more closely with you than an external agency. Ad-hoc specialists For larger organisations it may sometimes be appropriate to bring in specialists to compliment an existing in-house team. For example specialists in accessibility, usability or design can often work well alongside an in-house team primarily made up of coders. Outsourcing Outsourcing is contracting out the management and development of a process or production to external sources. Many online businesses have found it desirable to outsource their website. While some businesses lack the in-house expertise, others find the logistics of managing the website distracts their attention from their core competencies and some other find it to be cost-effective. In the present scenario of IT, all organizations whether big or small, depend on outsourcing to stay competitive. This is quite advantageous as a wide range of options is available, in the form of experienced reliable companies offering their services. Outsourcing helps a company to focus on its core business more efficiently. Outsourcing Advantages: You can be assured that if you go this route you are leaving all of your content needs in the hands of very well experienced and trained writers writers that have written for the Internet for a long period of time. There will more than likely be a whole team of editors, project managers, and writers and they will have a their system down pat already and will be ready to take on whatever kind of volume you need to push. You will have a faster turnaround time, and therefore you will be able to scale up quite easily. Outsourcing your content will also save you a lot of time and money. Hiring and training in-house writers takes a lot of time and can also be quite expensive. Outsourcing your content to a company usually means you will spend less money because they usually charge less and you wont have to spend money building up your own resources . Disadvantages: One of the major disadvantages is the differences in writing style that you may see. Outsourcing your content means outsourcing to a number of different writers, all of which have their own unique writing style. Since they have already been trained to write a certain way for the Internet, you will have to make sure that the writers will be able to fulfill your standards in terms of style and SEO needs. For example some people may want a double space after each period and some people like the single space approach. It seems like a small problem, but little problems like that can cause a lot of trouble if not worked out before the project gets started. This problem really escalates if you are outsourcing your content to many different freelancers. Language or cultural differences: Struggling to understand your tech support specialist can make a frustrating situation even worse. Unfortunately, many small businesses choose offshore outsourcing as their least-expensive option, while not considering the time and aggravation spent on communication issues. This can be mitigated either by carefully interviewing various offshore firms and giving them a test drive, or by hiring a local firm. The latter may also allow you to have the specialist on-site, which is highly recommended for handling most IT support needs. Not part of the team: Because outsourced IT specialists are there only when scheduled or when you need them to fix a problem, youll spend time bringing them up to speed when issues do arise or when you want them to provide advice on future technology initiatives. Again, there is a solution: Get an outsourced firm involved in your IT needs on an ongoing basis via managed services. Companies best interest The best for my company would be outsourcing because its gives us a saver web-hosting and trusted from virus. Although its not cheap but it would be easy for us because its been maintain and updated always. This could increase our web viewers and customers too. Conclusion Once you have a team of writers, you will always have to find a way to keep them busy or else you will risk losing them. If you dont have the ability to keep a team of writers busy for a substantial amount of time, then hiring in-house writers would prove to be a big waste of time. Your turnaround time will also not be as fast, and you will spend more time dealing with your writers time that probably could have better been spent elsewhere. A good route to go (a route that many companies take) is to hire a few in-house writers as well as outsource content needs that make sense to outsource. The Internet business calls for unique situations and needs, and the route you go with your content creation should definitely be based on these specific needs. One thing to be aware of is that some information technology consultants that you outsource to, will in turn outsource services to their own partners. Look for companies that take final responsibility for your system, no matter whether the y or a partner provided a particular service. This will help make things simpler for your organization, especially at times of stress and concern when you most need things to be easy.

Is Television a Bad Influence on Children Essay

The television has become such an integral part of homes in the modern world that it is hard to imagine life without television. It provides entertainment to people of all ages especially children. Children love to watch TV and prefer to stay â€Å"glued† to the TV screen all day, rather than playing outside. In the USA, 47% of children ages 2 to 18 years have a television set in their bedrooms. On a typical day, they spend on average of 5. 5 hours using media, including television, computer games and the Internet (Kaiser Family Foundation, 2001). TV is the number one after-school activity for 6 to 17 years old. see more:impact of television on children essay Although television is loved by children and has helped them a lot, it has influenced them in a negative way. Some optimistic people can argue that children should be allowed to watch a lot of television because it is educational. Preschoolers can get help to learn the alphabet on children’s programs such as â€Å"Takalani Sesame† and grade scholars can learn about wildlife on nature shows. However, with the increased rate of working parents, most children come home from school and are left alone or with a babysitter who may not care what the children watch on TV. With no supervision nearby, children may end up watching shows with violence, sex and bad language. Children that view such shows are likely to fear that the world is scary or that something bad will happen to them. Furthermore, the children will start to show aggressive behavior or start to behave like what they see on TV. (Bandura & Ross 1963) Television has become such an integral part of homes in the modern world that it is hard to imagine life without one. It provides entertainment to people of all ages, especially children, who, consequently would prefer to stare at the TV screen all day rather than going outside to play anymore. An online journal that I read called Journal of Youth and Adolescence states that television is an easy and inexpensive way to get information, it’s the most popular way for Americans old and young to get informed. Informed on what? With the increased rate of working parents, most children come home from school and are left alone or with a babysitter who may not care what the children atch. With no supervision nearby, children may end up watching shows with violence, sex, and bad language. The journal then goes on to say that TV allows us to create a national culture because it gives people something in common to talk about. I hear it everyday, most people are talking about their comedy shows that they watched the night before rather than what they saw on the nightly news. In this generation we have to many choices. The journal also stated that children have a choice on what to watch and how long they watch television. For me, this argument is unrealistic because most children do not have self discipline. They would rather watch something entertaining rather than a documentary about nature or history for example. They would rather watch the latest â€Å"Transformers† movie which is not suitable for young children. Firstly, children’s thinking skills can be adversely affected if they watch inappropriate television programs for a long period. According to Sharif (1999), short segments with interesting presentation in modern children’s programs and music video clips encourage the development of short attention spans in children. Children may have the wrong thoughts that overwhelming all the difficulties in life will be a piece of cake as they are used to thirty minutes problem-solving programs like ‘Friends’. As a result, they always lose out patience when it is the real time for them to counter the hardship and rigor situations. Moreover, Jones claims that children who are heavy viewers are among the lowest achievers at school because they do not develop imaginative skills to create fictitious characters, situations and make-believe worlds (Leigh 2001). In short, excessive television watching hours may plague the healthy thinking of the children Secondly, the structure of children’s behaviors’ will be less desirable, particularly the emanating of wildness and violence. Television programs and even the news, televised at prime time, depict violence scenes which may cause the children to become desensitized to violence (Sharif 1999). Consequently, they may feel that violence is a plausible and acceptable way in solving problems. Furthermore, some children attempt to imitate the superhero in the television shows they have watched. For instance, there were children jumped out of trees in Superman costumes and got themselves injured (Sharif 1999). Besides, the stereotyped movies showing the narrow roles of characters played by the women and men in society influence the children’s behaviors’ towards themselves and others. These evidences prove that television viewing can be actually harmful by forming disfavor behaviors’ among children. Prolonged periods in front of the television which is a sedentary activity can trigger many health problems such as obesity and related diseases. Nowadays, people, especially the youngsters, become inured to the habits of indulging themselves with snacks while watching television (Rutherford 2002). The elevated number of couch potatoes is intractable as it spreads erratically without control. Meanwhile, extended periods in front of the television mean that children are not being physically active (Sharif 1999). Moreover, children may become autistic as television viewing encourages the development of antisocial behavior. Briefly, obesity will become the most discernible fallout when children consume too much calories, adding to the dearth of physical exercises. In conclusion, I strongly believe that television viewing can bring harmful effects such as underdevelopment of thinking skills, negative forms of behaviors’ and unhealthy lifestyles. The negative effects of television viewing are stark, albeit, some people assert that its pros outweigh the cons. However, I am prone to the stance that television viewing brings more harms than benefits. A balance point on television viewing should be adhered in order to best utilize the television by minimizing its negative effects and at the same time get ourselves refreshed and ready to concentrate on things like homework.

Nigeria Essay - 2820 Words

Nigeria Modern Nigeria is an archetypal cauldron, enmeshed with a variety of cultural groups and traditions, nevertheless united by the prospect of forging a unique independent national identity.

Police Corruption - 2732 Words

Police corruption is a complex issue. Police corruption or the abuse of authority by a police officer, acting officially to fulfill personal needs or wants, is a growing problem in the United States today. Things such as an Internal Affairs department, a strong leadership organization, and community support are just a few considerations in the prevention of police corruption. An examination of a local newspaper or any police-related publication in an urban city during any given week would most likely have an article about a police officer that got caught committing some kind of corrupt act. Police corruption has increased dramatically with the illegal cocaine trade, with officers acting alone or in-groups to steal money from dealers or†¦show more content†¦At the urging of the Knapp Commission, the investigative body heard Officer Frank Serpico and other police officers describe a citywide network of rogue cops(New York Times, March 29, 1993: p 8). Later, in the same Manhatt an hearing room where the Knapp Commission once sat, the new body heard Dowd and other officers add another lurid chapter to the old story of police corruption. Many American cities were now worried that drug money will turn their departments bad (New York Times, April 3, 1993: p. 5). Reports have shown that the large majority of corrupt acts by police involve payoffs from both the perpetrators and the victims of victimless crimes. The Knapp commission in New York found that although corruption among police officers was not restricted to this area, the bulk of it involved payments of money to the police from gamblers and prostitutes (Knapp Commission Report, 1973: PP 1-3). The cops who were engaged in corruption 20 years ago took money to cover up the criminal activity of others, says Michael Armstrong, who was chief counsel to the Knapp Commission. Now it seems cops have gone into competition with street criminals (Newsweek, Oct 21,1992: p. 18). Gambling syndicates in the 1950s wer e protected by a payoff system more elaborate than the Internal Revenue Service.
