Law of rentThe law of rent states that the rent of a land site is equal to the economic advantage obtained by using the site in its most productive use, relative to the advantage obtained by using marginal (i.e., the best rent-free) land for the same purpose, given the same inputs of labor and capital. The law of rent was formulated by David Ricardo around 1809, and presented in its most developed form in his magnum opus, On the Principles of Political Economy and Taxation. This is the origin of the term "Ricardian rent".
Social identity approach"Social identity approach" is an umbrella term designed to show that there are two methods used by academics to describe certain complex social phenomena- namely the dynamics between groups and individuals. Those two theoretical methods are called social identity theory and self-categorization theory. Experts describe them as two intertwined, but distinct, social psychological theories. The term "social identity approach" arose as an attempt to mitigate against the tendency to conflate the two theories, as well as the tendency to mistakenly believe one theory to be a component of the other.
NonviolenceNonviolence is the personal practice of not causing harm to others under any condition. It may come from the belief that hurting people, animals and/or the environment is unnecessary to achieve an outcome and it may refer to a general philosophy of abstention from violence. It may be based on moral, religious or spiritual principles, or the reasons for it may be strategic or pragmatic. Failure to distinguish between the two types of nonviolent approaches can lead to distortion in the concept's meaning and effectiveness, which can subsequently result in confusion among the audience.
Identity (philosophy)In philosophy, identity (from identitas, "sameness") is the relation each thing bears only to itself. The notion of identity gives rise to many philosophical problems, including the identity of indiscernibles (if x and y share all their properties, are they one and the same thing?), and questions about change and personal identity over time (what has to be the case for a person x at one time and a person y at a later time to be one and the same person?). It is important to distinguish between qualitative identity and numerical identity.
Travesti (gender identity)The term travesti is used in Latin America to designate people who were assigned male at birth and develop a feminine gender identity. Other terms have been invented and are used in South America in an attempt to further distinguish it from cross-dressing, drag, and pathologizing connotations. In Spain, the term was used in a similar way during the Franco era, but it was replaced with the advent of the medical model of transsexuality in the late 1980s and early 1990s, in order to rule out negative stereotypes.
