Living wageA living wage is defined as the minimum income necessary for a worker to meet their basic needs. This is not the same as a subsistence wage, which refers to a biological minimum, or a solidarity wage, which refers to a minimum wage tracking labor productivity. Needs are defined to include food, housing, and other essential needs such as clothing. The goal of a living wage is to allow a worker to afford a basic but decent standard of living through employment without government subsidies.
Labor history of the United StatesThe nature and power of organized labor in the United States is the outcome of historical tensions among counter-acting forces involving workplace rights, wages, working hours, political expression, labor laws, and other working conditions. Organized unions and their umbrella labor federations such as the AFL–CIO and citywide federations have competed, evolved, merged, and split against a backdrop of changing values and priorities, and periodic federal government intervention.
Structural integrity and failureStructural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively.
Vector spaceIn mathematics and physics, a vector space (also called a linear space) is a set whose elements, often called vectors, may be added together and multiplied ("scaled") by numbers called scalars. Scalars are often real numbers, but can be complex numbers or, more generally, elements of any field. The operations of vector addition and scalar multiplication must satisfy certain requirements, called vector axioms. The terms real vector space and complex vector space are often used to specify the nature of the scalars: real coordinate space or complex coordinate space.
Workers' councilA workers' council, or labor council, is a type of council or popular assembly in a workplace or a locality made up of workers or of temporary and instantly revocable delegates elected by the workers in a locality's workplaces. In such a system of political and economic organization, the workers themselves are able to exercise decision-making power. Furthermore, the workers within each council decide on what their agenda is and what their needs are.
Orientation (vector space)The orientation of a real vector space or simply orientation of a vector space is the arbitrary choice of which ordered bases are "positively" oriented and which are "negatively" oriented. In the three-dimensional Euclidean space, right-handed bases are typically declared to be positively oriented, but the choice is arbitrary, as they may also be assigned a negative orientation. A vector space with an orientation selected is called an oriented vector space, while one not having an orientation selected, is called .
Health careHealth care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care.
