Essay on individuals who have contributed significantly to the development of computing as we know it essays Essay on individuals who have contributed significantly to the development of computing as we know it Computing, as we know it has developed greatly and rapidly in the last fifty years or so. Many individuals can be said to have contributed to the computer revolution this century, some more than significantly than others. This is assignment will concentrate on a few of these individuals and describe their pioneering achievements along with the circumstances and situations in which they materialised. The person who arguably made the most important contribution to the development of computing was an army radar technician named Douglas Engelbart. Back in 1945, he read Vannevar Bush's article As We May Think, and he had a vision! His vision was that computer-based tools could augment human intellect, thus improving our overall ability to tackle the problems and goals of the individual, and of society. During the 1950's and 60's Douglas Engelbart went on to develop the mouse, many of the features that are found in all GUI's, integrated help systems, electronic mail, teleconferencing, and interactive Hypermedia. In 1963, he set out the conceptual framework for an interactive hypermedia system in a paper entitled, A Conceptual Framework for the Augmentation of Man's Intellect. In 1968, he had completed the NLS (oN Line System), which was the early realisation of Engelbart's concept of an Augmentation System. NLS pioneered many of the features that are now integral to modern online multimedia systems; mouse, windows, e-mail, word processing, and hypertext. To Engelbart, hypertext was quite important to his Augmentation System. That it would allow users to expand the information available to them, facilitate collaborative authoring, and become a critical focus for community, all key elements of the WEB, which is a vital part of modern day computing.

Christmas Trends, Demographics, Spending and Waste

Christmas Trends, Demographics, Spending and Waste Christmas is one of the most widely celebrated holidays by people all over the world, but what are the particularities of it in the United States? Who is celebrating it? How are they doing it? How much are they spending? And how might social differences shape our experience of this holiday? Lets dive in. The Cross-Religion and Secular Popularity of Christmas According to Pew Research Centers December 2013 survey about Christmas, we know that the vast majority of people in the U.S. celebrate the holiday. The survey confirms what most of us know: Christmas is both a religious and a secular holiday. Unsurprisingly, about 96 percent of Christians celebrate  Christmas, as do a whopping 87 percent of people who are not religious. What may surprise you is that people of other faiths do too. According to Pew, 76 percent of Asian-American Buddhists, 73 percent of Hindus, and 32 percent of Jews celebrate Christmas. News reports indicate that some Muslims also celebrate the holiday. Interestingly, the Pew survey found that Christmas is more likely to be a religious holiday for older generations.  While just over a third  of people ages 18-29 celebrate Christmas religiously, 66 percent of those 65 and older do so. For many Millennials, Christmas is a cultural, rather than a religious, holiday. Popular Christmas Traditions and Trends According to the 2014 National Retail Federations (NRF) survey of planned activities for Christmas Day, the most common things we do are visit with family and friends, open gifts, cook a holiday meal, and sit on our bums and watch television. Pews 2013 survey shows that more than half of us will attend church on Christmas Eve or Day, and the organizations 2014 survey shows that eating holiday foods is the activity that we most look forward to, after visiting with family and friends. Leading up to the holiday, the Pew survey found that  the majority of American adults- 65 percent- will send holiday cards, though older adults are more likely than younger adults to do so, and 79 percent of us will put up a Christmas tree, which is slightly more common among higher income earners. Though hurtling through airports at top foot-speed is a popular trope of Christmas movies, in fact, just 5-6 percent of us travel long-distance by air for the holiday, according to the U.S. Department of Transportation. While long-distance travel  increases by 23 percent at Christmas time, most of that travel is by car. Similarly, though images of carolers punctuate holiday films, just 16 percent of us join in the activity, according to Pews 2013 survey Studies also show that we are getting engaged, conceiving children, and deciding to get divorced more so on Christmas than during any other time of  the year. How Gender, Age, and Religion Shape Our Christmas Experiences Interestingly, a 2014 survey by Pew found that religious affiliation, gender,  marital status, and age have an impact on the extent to which people look forward to the  common ways of celebrating Christmas. Those who regularly attend religious services are more enthusiastic on average about Christmas activities than are those who attend less often, or not at all. The only activity that escapes this rule? Americans universally look forward to eating holiday foods. In terms of gender, the survey found that, with the exception of visiting with family and friends, women look forward to the holiday traditions and activities more than men. While the Pew survey did not establish a reason for why this is the case, existing social science suggests that it could be because women spend more time than men do shopping and visiting with or taking care of family members in the context of their everyday lives. Its possible that mundane and taxing chores are more appealing to women when they are surrounded by the Christmas glow. Men, however, find themselves in the position of having to do things that they are not normally expected to do, and so they dont look forward to these events as much as women do. Echoing the fact that Christmas is less of a religious holiday for Millennials than it is for older generations, the 2014 Pew survey results indicate an overall generational shift in how we celebrate the holiday. Americans over the age of 65 are more likely than others to look forward to hearing Christmas music and attending religious services, while those in the younger generations are more likely to look forward to eating holiday foods, exchanging gifts, and decorating their homes. And while the majority of all generations do these things, Millennials are the most likely to buy gifts for others, and the least likely to send Christmas cards (though still a majority do it). ChristmasSpending: Big Picture, Averages, and Trends More than  $665  billion is the amount the NRF forecasts  Americans will spend during November and December 2016- an increase of 3.6 percent over the previous year. So, where will all that money go? Most of it, on average $589, will go  to gifts, out of a total $796 that the average person will spend. The rest will be spent on  holiday items including candy and food (about $100), decorations (about $50), greeting cards and postage, and flowers and potted plants. As part of that decorative budget, we can expect Americans to collectively  spend more than $2.2 billion on about 40 million Christmas trees in 2016 (67 percent real, 33 percent fake), according to  data from the National Christmas Tree Association. In terms of gift-giving plans, the NRF survey shows American adults intend to buy and give the following: Clothing or accessories (61%)Gift cards or certificates (56%)Media items (books, music, videos, games, etc.) (44%)Toys (42%)Food or candy (31%)Consumer electronics (30%)Personal care or beauty items (25%)Jewelry (21%)Home decor or furnishings (20%)Cash (20%)Sporting goods or leisure items (17%) The plans adults have for gifts for children reveal the stronghold that gender stereotypes still have in American culture. The top five toys that people plan to buy for boys include Lego sets, cars and trucks, video games, Hot Wheels, and Star Wars items. For girls, they plan to buy Barbie items, dolls, Shopkins, Hatchimals, and Lego sets. Given that the average person intends to spend nearly $600 on gifts, its not surprising that nearly half of all American adults feel that exchanging gifts leaves them stretched thin financially (according to Pews 2014 survey). More than a third of us feel stressed out by our countrys gift-giving culture, and nearly a quarter of us believe that it is wasteful. The Environmental Impact Have you ever thought about the environmental impact of all this Christmas cheer? The Environmental Protection Agency reports that household waste increases by more than 25 percent between Thanksgiving and New Years Day, which results in an additional 1 million tons per week going to landfills. Gift wrapping and shopping bags amount  to a whopping  4 million tons  of Christmas-related trash. Then theres all the cards, ribbons, product packaging, and trees too. Though we think of it as a time of togetherness, Christmas is also a time of massive waste. When one considers this and the financial and emotional stress of consumerist gift-giving, perhaps a change of tradition is in order?

The anti-Cancer activity of Rhein in Leukaemia Essay - 1

The anti-Cancer activity of Rhein in Leukaemia - Essay Example The tissue wherever the cells are deposited gets clogged and their function is compromised. Along with the increased proliferation of a set of WBCs, the normal red blood cells (RBC), as well as the platelet synthesis in severely impaired (Ciesla, 2007). The normal function of the bone marrow is also suppressed causing a generalized bone marrow failure. The compromised synthesis and maturation of RBC causes reduction in total circulating RBCs and hence reduced hemoglobin termed as anaemia. The leukaemia cells (like all the other malignant cells) have a tendency to invade the distant organs and tissues known as metastasis. These cells thus enter and get deposited in liver, spleen and lungs where the macrophages of the reticuloendothelial system are highly active. The reduced platelet generation from the impaired bone marrow is responsible for the spontaneous bleeding seen in advanced stages of leukemia. Leukaemia can be divided into four classes, viz. acute myeloid, chronic myeloid, acute lymphoid and chronic (Hoffbrand et al, 2006). The acute leukeamia has rapid onset, and is characterized by the presence of blasts and other immature cells in blood. It may present in any age group of subjects and the organo-megali is not very pronounced. (Sekeres et al, 2007). On the other hand, chronic leukaemia is characterized by slow and subtle onset, primarily affects the adults and the blood profile shows increased concentration of mature white blood cells. In Britain, the incidence of leukaemias is quite less compared to the other types of cancer, accounting for about 3% of all cases. Less than 10000 new cases of leukaemia are being reported in UK (Cancer research UK). Therefore, although not very common, the high morbidity and mortality associated with leukaemia makes it an of great concern. A cancer cell lines are always derived from the patient harboring the malignant cells. The cancer cells from patients with specific characteristics are isolated and stabilized

The major problem or issue currently facing natural resource managers Assignment

The major problem or issue currently facing natural resource managers in agriculture - Assignment Example The resource based activities in which the rural poor are engaged in include petite extent farming, animal production, fishing, hunting, mining and logging. They therefore rely on returns from these activities as their most important sources of earnings. They therefore plummet back to innate wherewithal when these sources fail. For them the natural resources foster consistency and reinforce the net security of the entire community. Bell and Park (2006) explain that the above does not however mean that the rich live their lives independent of natural resources. They derive more ecological proceeds from natural resources because they are proficient to exercise stronger control over the resources due to their greater administrative influence they have as compared to the underprivileged. One of the major problems facing environmental managers is scheming and preventing environmental degradation. Its impact spread to all aspects of the economy and not just the surroundings. Environmental slump leads to loss of species that impact negatively on the environment and abridged agricultural productivity that lead to poor economic growth. Bates (2003) explained that those who rely on the environment should do so with resilience and little or no vulnerability. Therefore, the problem faced by natural resource managers is how to ensure that the resources are used with pliability or less susceptibility while at the same instance deriving benefits. The strain in the natural resources is caused by uninhibited increase in population growth, this increases dependency on grain imports, loss of biodiversity and neglect of conventional farming techniques. This is caused by the migration of people to the urban areas to look for employment (Bellamy, Meppem, Gorddard and Dawson 2005). The establishment, testing and continuation of adaptive capability of natural and societal systems is becoming of huge concern to the managers in agricultural sector because of unfavorable climate change, poor water use and management in Australia. The actions of human beings are of great concern because they impact on natural resources with greater implications on social and economic development, sustainable livelihoods and environmental management. Land use and greater pressure on social systems are caused by increase in bucolic non farm money-making activities and increased urban population. Emergence of the problem of environmental conservation is of great complexity due to the multiple causes, problem perspectives and solution approaches. The solution approaches are also faced with poor institutional settings. Part of the solution approaches to curb the problem of conservation therefore requires a shift from federalism to proper ascendancy. This leads to interrelations of processes, structures and tasks. Australia represents countries with accelerating levels of environmental degradation and the complexity of natural resource ascendancy. There are however frameworks within the A ustralian Federal System to address the accelerating periodic challenges of sustainable natural resource and social systems. Sustainable formation, testing and maintenance of opportunities therefore refer to the goal of nurturing capabilities and creating viable opportunities. New-fangled cohort of authority in Australia is experimented to deal with issues relating to vitality of varying

Enemy At The Gates Essay -- essays research papers

Enemy at the Gates, a film with intense violence and man’s inhumanity to man, tells the story of the triumph of love and friendship set amidst the brutality of World War II Stalingrad. It is the winter of 1942, and a desperate, poorly equipped and demoralized Russian army faces the possibility of crushing defeat by the might of the German blitzkrieg. A young naà ¯ve soldier from the Urals, Vassily Zaitsev, arrives in Stalingrad where he is thrust into battle amid the needless slaughter of his fellow soldiers be the Germans and his own troops. To his shock, he is not given a rifle to use during the attack. Instead, the men are paired together and one is given a rifle while the other is given extra ammunition. Vassily survives the first fierce assault and finds himself side-by-side with the political officer, Danilov. They are trapped among the bodies of fallen Russian soldiers behind the lines, and Vassily’s talent as a sniper, homed to perfection from a childhood spent hunting wolves with his grandfather, is realized by Danilov when Vassily calmly and methodically kills five German soldiers. Returning to the relative safety of Russian controlled sector in t he city, Danilov, a writer, glorifies Vassily’s exploits in a newspaper article. So begins the unlikely friendship between the highly educated political officer Danilov and the barely literate Private Vassily Zaitsev. Vassily is then elevated to the status of hero when Danilov suggests to an angry and demanding Nikita Krusc...

Education Essay

Some students apply for admission only to their first-choice school, while others apply to several schools. Which plan do you agree with, and why? Be sure to include details and examples to support your opinion. I am of the opinion that is better to apply to several schools instead of only to your first-choice school. I think that this plan gives you more options to be accepted in one university, help you improve your applications and open you other opportunities that you could not have considered. I think that applying to just one school is very risky. Probably, you first-choice school is one of the best of the country so it receives a lot of applications each year and the selection process is extremely competitive. Therefore, you have to consider that the odds of not being accepted are high. If this is the case, you will have to wait until the next year to go to the university. I think that taking this risk is unnecessary and you avoid it by simply applying to more than one school. Secondly, doing all the paper work for different universities lets you improve your applications. As different universities ask you to write about different aspects of your personality, interests, goals, etc. you learn more about yourself. As a result, you can improve all your applications, especially the one for your first-choice school, and your chances to be admitted increase. Finally, doing the application process for other schools than your first-option school lets you know other universities. Sometimes, when you finish high school, you just consider one university. This might be the one where your parents or brother go, and the one which your favorite professor recommended you. However, there could be other good universities with different academic curricula and some of these other schools could even fit to your goals and interest better. Exploring and applying to other schools, give you the opportunity to learn more about these other schools. Therefore, I think that applying to more than one schools have many advantages. It is a less risky plan, lets you improve your application and open you to new opportunities in other schools. Moreover, the cost of this plan is low because once you have done one applications, the following ones are much easier and takes far less time.

State Of The American Dream - 1524 Words

State of The American Dream Seroux Alexandre English 1100 Sec. 53 Prof. Sidhu 5 November 2015 1 2 The American Dream is supposed to be a society where every American  ­ regardless of demographical status  ­ has the equal opportunity to be successful through hard work and determination. However, the American Dream, is not accessible to every American. In fact, the vast majority of Americans are deprived of opportunities for one reason or another. Mostly, poverty and lack of education are the obstacles that prevent Americans of certain demographics from being successful. Once someone is born into poverty, it is a never ­ending cycle that is nearly impossible to break. This person cannot afford higher education which is shown to correlate with more success. There are other inhibiting factors for success; most of which are permanent. One demographic that faces many inequalities is the female population. Girls are exposed to social pressures that condition them to be unsuccessful; they are taught by society that they are inferior. Women face social injustices, income inequality, and discrimination in the workplace which affect their abilities to prosper in American society. Even women of a dominant race will be deprived of the American Dream and have a shorter life expectancy just by being in poverty.
