Boundary-work is part of science studies. In boundary-work, boundaries, demarcations, or other divisions between fields of knowledge are created, advocated, attacked, or reinforced. Such delineations often have high stakes for the participants, [1] and carry the implication that such boundaries are flexible and socially constructed. [citation ...
This concept has since been widely cited and the concept of a boundary object has been adopted in computer science (particularly computer supported cooperative work), information science, [4] and management, particularly when considering cross-disciplinary work and collaboration, [5] either within one organization or with the boundary object helping to focus the efforts of multiple organizations.
The concept "boundary organization" was originally coined by Guston (1999) to discuss the concept of boundary work to illustrate why the distinction between science and non-science is not as subtle as formerly thought. [4] Guston put forward the idea of boundary organizations to stabilize the boundary between scientists and policymakers.
The definition of a type 1 and type 2 sequence was first introduced by Vail et al. (1984). [4] Since they were hard to recognize, they were redefined in 1990 by Van Wagoner et al.. However even with this new definition, type 2 sequence boundaries were hard to recognize in the field due to their lack of subaerial exposure.
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
Boundary (chain complex), its abstractization in chain complexes; Boundary value problem, a differential equation together with a set of additional restraints called the boundary conditions; Boundary (thermodynamics), the edge of a thermodynamic system across which heat, mass, or work can flow
In topology and mathematics in general, the boundary of a subset S of a topological space X is the set of points in the closure of S not belonging to the interior of S. An element of the boundary of S is called a boundary point of S. The term boundary operation refers to finding or taking the boundary of a set.
Rigid boundary – not allowing exchange of work: A mechanically isolated system One example is fluid being compressed by a piston in a cylinder. Another example of a closed system is a bomb calorimeter , a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction.
