AgentivitéEn sciences sociales et en philosophie, l'agentivité, adaptation de l'anglais « agency », terme utilisé notamment au Canada, est la faculté d'action d'un être, sa capacité à agir sur le monde, les choses, les êtres, à les transformer ou les influencer. Comme l'explique la sociologue Monique Haicault, traduire le concept d'agency en français « n'est pas simple » : il s'agit encore actuellement d'un « univers sémantique en construction ».
Social simulationSocial simulation is a research field that applies computational methods to study issues in the social sciences. The issues explored include problems in computational law, psychology, organizational behavior, sociology, political science, economics, anthropology, geography, engineering, archaeology and linguistics . Social simulation aims to cross the gap between the descriptive approach used in the social sciences and the formal approach used in the natural sciences, by moving the focus on the processes/mechanisms/behaviors that build the social reality.
Conceptual modelA conceptual model is a representation of a system. It consists of concepts used to help people know, understand, or simulate a subject the model represents. In contrast, a physical model focuses on a physical object such as a toy model that may be assembled and made to work like the object it represents. The term may refer to models that are formed after a conceptualization or generalization process. Conceptual models are often abstractions of things in the real world, whether physical or social.
Level of analysisLevel of analysis is used in the social sciences to point to the location, size, or scale of a research target. It is distinct from unit of observation in that the former refers to a more or less integrated set of relationships while the latter refers to the distinct unit from which data have been or will be gathered. Together, the unit of observation and the level of analysis help define the population of a research enterprise.
Three-schema approachThe three-schema approach, or three-schema concept, in software engineering is an approach to building information systems and systems information management that originated in the 1970s. It proposes three different views in systems development, with conceptual modelling being considered the key to achieving data integration.
Rational choice theory (criminology)In criminology, rational choice theory adopts a utilitarian belief that humans are reasoning actors who weigh means and ends, costs and benefits, in order to make a rational choice. This method was designed by Cornish and Clarke to assist in thinking about situational crime prevention. The rational choice theory has sprung from older and more experimental collections of hypotheses surrounding what has been essentially, the empirical findings from many scientific investigations into the workings of human nature.
International relations theoryInternational relations theory is the study of international relations (IR) from a theoretical perspective. It seeks to explain behaviors and outcomes in international politics. The four most prominent schools of thought are realism, liberalism, constructivism, and rational choice. Whereas realism and liberalism make broad and specific predictions about international relations, constructivism and rational choice are methodological approaches that focus on certain types of social explanation for phenomena.
Dynamique socialeLa dynamique sociale, renvoie, en sociologie, aux changements ou aux étapes successives dans l'évolution des faits sociaux. Elle permet d'envisager la société sous l'angle de son évolution. Elle complète la notion de statique socialeLa science sociale (1819-1822), introduction UQAC, A. Kremer-Marietti, 4 novembre 2006.. On retrouve le terme en chez Auguste Comte, dans son livre Système de politique positive, ou Traité de sociologie instituant la religion de l'humanité, dont le troisième tome s'appelle De la dynamique sociale.
Conceptual metaphorIn cognitive linguistics, conceptual metaphor, or cognitive metaphor, refers to the understanding of one idea, or conceptual domain, in terms of another. An example of this is the understanding of quantity in terms of directionality (e.g. "the price of peace is rising") or the understanding of time in terms of money (e.g. "I spent time at work today"). A conceptual domain can be any mental organization of human experience.
Densité de courantLa densité de courant, ou densité volumique de courant, est un vecteur qui décrit le courant électrique à l'échelle locale, en tout point d'un système physique. Dans le Système international d'unités, son module s'exprime en ampères par mètre carré ( ou ). À l'échelle du système tout entier il s'agit d'un champ de vecteurs, puisque le vecteur densité de courant est défini en tout point.
