Capitanian mass extinction eventThe Capitanian mass extinction event, also known as the end-Guadalupian extinction event, the Guadalupian-Lopingian boundary mass extinction, the pre-Lopingian crisis, or the Middle Permian extinction was an extinction event that predated the end-Permian extinction event. The mass extinction occurred during a period of decreased species richness and increased extinction rates near the end of the Middle Permian, also known as the Guadalupian epoch.
Negative and positive rightsThe right of person A to obligate (enforce an obligation on) person B to refrain from (causal) physical interference with, in particular a purely interfering negligence tort against, some object or thing is called a negative right. So a negative right is a claim right. If a claim right is not a negative right, it is called a positive right. To every claim right of person A to obligate person B corresponds the obligation on B, so the obligation corresponding to a negative right is called a 'negative obligation' and an obligation corresponding to positive right a 'positive obligation'.
Invented traditionInvented traditions are cultural practices that are presented or perceived as traditional, arising from the people starting in the distant past, but which in fact are relatively recent and often even consciously invented by identifiable historical actors. The concept was highlighted in the 1983 book The Invention of Tradition, edited by Eric Hobsbawm and Terence Ranger. Hobsbawm's introduction argues that many "traditions" which "appear or claim to be old are often quite recent in origin and sometimes invented.
Regional powerIn international relations, since the late 20th century, the term "regional power" has been used for a sovereign state that exercises significant power within a given geographical region. States that wield unrivaled power and influence within a region of the world possess regional hegemony. Regional powers shape the polarity of a regional area. Typically, regional powers have capabilities which are important in the region, but do not have capabilities at a global scale. Slightly contrasting definitions differ as to what makes a regional power.
Civil societyCivil society can be understood as the "third sector" of society, distinct from government and business, and including the family and the private sphere. By other authors, civil society is used in the sense of 1) the aggregate of non-governmental organizations and institutions that advance the interests and will of citizens or 2) individuals and organizations in a society which are independent of the government.
Civic nationalismCivic nationalism, also known as democratic nationalism and liberal nationalism, is a form of nationalism that adheres to traditional liberal values of freedom, tolerance, equality, individual rights and is not based on ethnocentrism. Civic nationalists often defend the value of national identity by saying that individuals need it as a partial shared aspect of their identity (an upper identity) in order to lead meaningful, autonomous lives and that democratic polities need national identity to function properly.
Environmental politicsEnvironmental politics designate both the politics about the environment (see also environmental policy) and an academic field of study focused on three core components: The study of political theories and ideas related to the environment; The examination of the environmental stances of both mainstream political parties and environmental social movements; and The analysis of public policymaking and implementation affecting the environment, at multiple geo-political levels.
Political geographyPolitical geography is concerned with the study of both the spatially uneven outcomes of political processes and the ways in which political processes are themselves affected by spatial structures. Conventionally, for the purposes of analysis, political geography adopts a three-scale structure with the study of the state at the centre, the study of international relations (or geopolitics) above it, and the study of localities below it. The primary concerns of the subdiscipline can be summarized as the inter-relationships between people, state, and territory.
National Bureau of Economic ResearchThe National Bureau of Economic Research (NBER) is an American private nonprofit research organization "committed to undertaking and disseminating unbiased economic research among public policymakers, business professionals, and the academic community". The NBER is known for providing start and end dates for recessions in the United States. Many chairpersons of the Council of Economic Advisers were previously NBER Research Associates, including the former NBER president and Harvard Professor, Martin Feldstein.
Quaternary extinction eventThe latter half of the Late Pleistocene to the beginning of the Holocene (~50,000-10,000 years Before Present) saw extinctions of numerous predominantly megafaunal species, which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by the widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence.
