Professional developmentProfessional development, also known as professional education, is learning that leads to or emphasizes education in a specific professional career field or builds practical job applicable skills emphasizing praxis in addition to the transferable skills and theoretical academic knowledge found in traditional liberal arts and pure sciences education. It is used to earn or maintain professional credentials such as professional certifications or academic degrees through formal coursework at institutions known as professional schools, or attending conferences and informal learning opportunities to strengthen or gain new skills.
Collective farmingCollective farming and communal farming are various types of, "agricultural production in which multiple farmers run their holdings as a joint enterprise". There are two broad types of communal farms: agricultural cooperatives, in which member-owners jointly engage in farming activities as a collective, and state farms, which are owned and directly run by a centralized government. The process by which farmland is aggregated is called collectivization.
Professional certificationProfessional certification, trade certification, or professional designation, often called simply certification or qualification, is a designation earned by a person to assure qualification to perform a job or task. Not all certifications that use post-nominal letters are an acknowledgement of educational achievement, or an agency appointed to safeguard the public interest. A certification is a third-party attestation of an individual's level of knowledge or proficiency in a certain industry or profession.
Still lifeA still life (plural: still lifes) is a work of art depicting mostly inanimate subject matter, typically commonplace objects which are either natural (food, flowers, dead animals, plants, rocks, shells, etc.) or human-made (drinking glasses, books, vases, jewelry, coins, pipes, etc.). With origins in the Middle Ages and Ancient Greco-Roman art, still-life painting emerged as a distinct genre and professional specialization in Western painting by the late 16th century, and has remained significant since then.
Mean squared displacementIn statistical mechanics, the mean squared displacement (MSD, also mean square displacement, average squared displacement, or mean square fluctuation) is a measure of the deviation of the position of a particle with respect to a reference position over time. It is the most common measure of the spatial extent of random motion, and can be thought of as measuring the portion of the system "explored" by the random walker.
Standard of livingStandard of living is the level of income, comforts and services available, generally applied to a society or location, rather than to an individual. Standard of living is relevant because it is considered to contribute to an individual's quality of life. Standard of living is generally concerned with objective metrics outside an individual's personal control, such as economic, societal, political and environmental matters – such things that an individual might consider when evaluating where to live in the world, or when assessing the success of economic policy.
Medieval artThe medieval art of the Western world covers a vast scope of time and place, with over 1000 years of art in Europe, and at certain periods in Western Asia and Northern Africa. It includes major art movements and periods, national and regional art, genres, revivals, the artists' crafts, and the artists themselves. Art historians attempt to classify medieval art into major periods and styles, often with some difficulty.
Usage share of operating systemsThe usage share of operating systems is the percentage of computing devices that run each operating system (OS) at any particular time. All such figures are necessarily estimates because data about operating system share is difficult to obtain. There are few reliable primary sources and no agreed methodologies for its collection. Operating systems are used in the vast majority of computers, from embedded devices to supercomputers.
Art historyArt history is the study of aesthetic objects and visual expression in historical and stylistic context. Traditionally, the discipline of art history emphasized painting, drawing, sculpture, architecture, ceramics and decorative arts; yet today, art history examines broader aspects of visual culture, including the various visual and conceptual outcomes related to an ever-evolving definition of art. Art history encompasses the study of objects created by different cultures around the world and throughout history that convey meaning, importance or serve usefulness primarily through visual representations.
Free FranceFree France (France Libre) was a political entity that claimed to be the legitimate government of France following the dissolution of the Third Republic. Led by French general Charles de Gaulle, Free France was established as a government-in-exile in London in June 1940 after the Fall of France during World War II and fought the Axis as an Allied nation with its Free French Forces (Forces françaises libres). Free France also supported the resistance in Nazi-occupied France, known as the French Forces of the Interior, and gained strategic footholds in several French colonies in Africa.
