Co-option (disambiguation)

Last updated

Co-option or coöption is a process of appointing members to a group, or an act of absorbing or assimilating.

Co-option has two common meanings. It may refer to the process of adding members to an elite group at the discretion of members of the body, usually to manage opposition and so maintain the stability of the group. Outsiders are ‘co-opted’ by being given a degree of power on the grounds of their élite status, specialist knowledge, or potential ability to threaten essential commitments or goals.

Co-option or coöption may also refer to:

Exaptation and the related term co-option describe a shift in the function of a trait during evolution. For example, a trait can evolve because it served one particular function, but subsequently it may come to serve another. Exaptations are common in both anatomy and behaviour. Bird feathers are a classic example: initially they may have evolved for temperature regulation, but later were adapted for flight. Interest in exaptation relates to both the process and products of evolution: the process that creates complex traits and the products that may be imperfectly developed.

The term co-option refers to the capacity of intracellular parasites to use host-cell proteins to complete their vital cycle. Viruses use this mechanism, as their genome is small.

In the United Kingdom, the General Certificate of Secondary Education (GCSE) is an academic qualification, generally taken in a number of subjects by pupils in secondary education in England, Wales and Northern Ireland.

In France, the agrégation is a competitive examination for civil service in the French public education system. Candidates for the examination, or agrégatifs, become agrégés once they are admitted to the position of professeur agrégé. In France, professeurs agrégés are distinguished from professeurs certifiés recruited through the CAPES training. The agrégés are usually expected to teach at high schools (lycées) and universities, while the certifiés usually teach in junior high schools (collèges), although there is a significant overlap.

The Natural Sciences Tripos (NST) is the framework within which most of the science at the University of Cambridge is taught. The tripos includes a wide range of Natural Sciences from physical sciences to biology which are taught alongside the history and philosophy of science. The tripos covers several courses which form the University of Cambridge system of Tripos. It is known for its broad range of study in the first year, in which students cannot study just one discipline, but instead must choose three courses in different areas of the natural sciences and one in mathematics. As is traditional at Cambridge, the degree awarded after Part II is a Bachelor of Arts (BA). A Master of Science degree (MSci) is available to those who take the optional Part III. It was started in the 19th Century.

The Group 4: Experimental sciences subjects of the International Baccalaureate Diploma Programme comprise the main scientific emphasis of this internationally recognized high school programme. They consist of seven courses, five of which are offered at both the Standard Level (SL) and Higher Level (HL): Chemistry, Biology, Physics, Design Technology, and, as of August 2012, Computer Science is offered as part of the Group 4 subjects. There are also two SL only courses: a transdisciplinary course, Environmental Systems and Societies, that satisfies Diploma requirements for Groups 3 and 4, and Sports, Exercise and Health Science. Astronomy also exists as a school-based syllabus. Students taking two or more Group 4 subjects may combine any of the aforementioned.

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis.

Oregon State University's College of Science is a college within Oregon State University consisting of 7 departments offering 9 undergraduate programs and houses 7 PhD granting programs and 8 Masters Degree granting programs. The college also offers classes for interdisciplinary science programs housed in other colleges. The college was founded in 1932 as the School of Science, when the OSU paleontologist Earl L. Packard became the first dean, as a result of the dramatic reorganization of the Oregon State System of Higher Education in the same year. The School of Science was renamed to the College of Science in 1974. The current dean is Roy Haggerty.

A compound option or split-fee option is an option on an option. The exercise payoff of a compound option involves the value of another option. A compound option then has two expiration dates and two strike prices. Usually, compounded options are used for currency or fixed income markets where insecurity exists regarding the option’s risk protection. Another common business application that compound options are used for is to hedge bids for business projects that may or may not be accepted.
