Office Work
A white-collar worker is a person who performs professional, desk, managerial, or administrative work. White-collar work may be performed in an office or other administrative setting. White-collar workers include job paths related to government, consulting, academia, accountancy, business and executive management, customer support, design, engineering, market research, finance, human resources, operations research, marketing, public relations, information technology, networking, law, healthcare, architecture, and research and development. Other types of work are those of a grey-collar worker, who has more specialized knowledge than those of a blue-collar worker, whose job requires manual labor. Etymology The term refers to the white dress shirts of male office workers common through most of the nineteenth and twentieth centuries in Western countries, as opposed to the blue overalls worn by many manual laborers. The term "white collar" is credited to Upton Sinclair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Science
Network science is an academic field which studies complex networks such as telecommunication networks, computer networks, biological networks, cognitive and semantic networks, and social networks, considering distinct elements or actors represented by ''nodes'' (or ''vertices'') and the connections between the elements or actors as ''links'' (or ''edges''). The field draws on theories and methods including graph theory from mathematics, statistical mechanics from physics, data mining and information visualization from computer science, inferential modeling from statistics, and social structure from sociology. The United States National Research Council defines network science as "the study of network representations of physical, biological, and social phenomena leading to predictive models of these phenomena." Background and history The study of networks has emerged in diverse disciplines as a means of analyzing complex relational data. The earliest known paper in this f ...

Obesity
Obesity is a medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it may negatively affect health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over ; the range is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity has individual, socioeconomic, and environmental causes. Some known causes are diet, physical activity, automation, urbanization, genetic susceptibility, medications, mental disorders, economic policies, endocrine disorders, and exposure to endocrine-disrupting chemicals. While a majority of obese individuals at any given time are attempting to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatigue (medical)
Fatigue describes a state of tiredness that does not resolve with rest or sleep. In general usage, fatigue is synonymous with extreme tiredness or exhaustion that normally follows prolonged physical or mental activity. When it does not resolve after rest or sleep, or occurs independently of physical or mental exertion, it may be a symptom of a medical condition that may become severe or progressive. Fatigue can be a feature of a mental disorder such as depression; may be associated with conditions of chronic pain such as fibromyalgia; it may also feature in conditions of chronic low-level inflammation, and be a disease-related symptom in many other conditions. Fatigue often has no known cause, and is recognised as being very complex in nature. Fatigability describes a susceptibility to fatigue. Physical fatigue results from muscle fatigue brought about by intense physical activity. Mental fatigue results from prolonged periods of cognitive activity which impairs cognitive abil ...

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the first and foundational historical dictionary of the English language, published by Oxford University Press (OUP). It traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. Work began on the dictionary in 1857, but it was only in 1884 that it began to be published in unbound fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 bound volumes. In 1933, the title ''The Oxford English Dictionary'' fully replaced the former name in all occurrences in its reprinting as 12 volumes with a one-v ...

Clerk (position)
A clerk is a white-collar worker who conducts general office tasks, or a worker who performs similar sales-related tasks in a retail environment. The responsibilities of clerical workers commonly include record keeping, filing, staffing service counters, screening callers, and other administrative tasks. History and etymology The word ''clerk'' is derived from the Latin ''clericus'' meaning "cleric" or "clergyman", which is the latinisation of the Greek ''κληρικός'' (''klērikos'') from a word meaning a "lot" (in the sense of drawing lots) and hence an "apportionment" or "area of land".

Upton Sinclair
Upton Beall Sinclair Jr. (September 20, 1878 – November 25, 1968) was an American writer, muckraker, political activist and the 1934 Democratic Party nominee for governor of California who wrote nearly 100 books and other works in several genres. Sinclair's work was well known and popular in the first half of the 20th century, and he won the Pulitzer Prize for Fiction in 1943. In 1906, Sinclair acquired particular fame for his classic muck-raking novel, ''The Jungle'', which exposed labor and sanitary conditions in the U.S. meatpacking industry, causing a public uproar that contributed in part to the passage a few months later of the 1906 Pure Food and Drug Act and the Meat Inspection Act. In 1919, he published ''The Brass Check'', a muck-raking exposé of American journalism that publicized the issue of yellow journalism and the limitations of the "free press" in the United States. Four years after publication of ''The Brass Check'', the first code of ethics for journ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dress Shirt
A dress shirt, button shirt, button-front, button-front shirt, or button-up shirt, is a garment with a collar and a full-length opening at the front, which is fastened using buttons or shirt studs. A button-down or button-down shirt is a dress shirt with a button-down collar – a collar having the ends fastened to the shirt with buttons. A dress shirt is normally made from woven cloth, and is often accompanied by a tie, jacket, suit, or formalwear, but a dress shirt may also be worn more casually. In British English, "dress shirt" ("formal shirt" or "tuxedo shirt" in American English) means specifically the more formal evening garment worn with black- or white-tie. Some of these formal shirts have stiff fronts and detachable collars attached with collar studs. History Traditionally dress shirts were worn by men and boys, whereas women and girls often wore blouses, sometimes known as chemises. However, in the mid-1800s, they also became an item of women's clothing an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Labor
Manual labour (in Commonwealth English, manual labor in American English) or manual work is physical work done by humans, in contrast to labour by machines and working animals. It is most literally work done with the hands (the word ''manual'' coming from the Latin word for hand) and, by figurative extension, it is work done with any of the muscles and bones of the human body. For most of human prehistory and history, manual labour and its close cousin, animal labour, have been the primary ways that physical work has been accomplished. Mechanisation and automation, which reduce the need for human and animal labour in production, have existed for centuries, but it was only starting in the 18th and 19th centuries that they began to significantly expand and to change human culture. To be implemented, they require that sufficient technology exist and that its capital costs be justified by the amount of future wages that they will obviate. Semi-automation is an alternative to worke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-collar Worker
A blue-collar worker is a working class person who performs manual labor. Blue-collar work may involve skilled or unskilled labor. The type of work may involving manufacturing, warehousing, mining, excavation, electricity generation and power plant operations, electrical construction and maintenance, custodial work, farming, commercial fishing, logging, landscaping, pest control, food processing, oil field work, waste collection and disposal, recycling, construction, maintenance, shipping, driving, trucking and many other types of physical work. Blue-collar work often involves something being physically built or maintained. In contrast, the white-collar worker typically performs work in an office environment and may involve sitting at a computer or desk. A third type of work is a service worker (pink collar) whose labor is related to customer interaction, entertainment, sales or other service-oriented work. Many occupations blend blue, white, or pink-collar work and are of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey-collar
Grey-collar refers to the balance of employed people not classified as white- or blue collar. It is occasionally used to describe elderly individuals working beyond the age of retirement, as well as those occupations that incorporate some of the elements of both blue- and white-collar, and generally are in between the two categories in terms of income-earning capability. Grey-collar workers often have licenses, associate degrees, certificates or diplomas from a trade school or technical school in a particular field. They are unlike blue-collar workers, who can often be trained on the job within several weeks, whereas grey-collar workers already have a specific skill set and require more specialized knowledge than their blue-collar counterparts. The fields that most recognize the differences between these two groups are human resources and the insurance industry. These different groups must be insured differently for liability, as the potential for injury is different. Examples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
