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.
Therapeutic effectTherapeutic effect refers to the response(s) after a treatment of any kind, the results of which are judged to be useful or favorable. This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect (including nocebo) is the converse and refers to harmful or undesired response(s). What constitutes a therapeutic effect versus a side effect is a matter of both the nature of the situation and the goals of treatment.
Environmental securityEnvironmental security examines threats posed by environmental events and trends to individuals, communities or nations. It may focus on the impact of human conflict and international relations on the environment, or on how environmental problems cross state borders. The Millennium Project assessed definitions of environmental security and created a synthesis definition: Environmental security is environmental viability for life support, with three sub-elements: preventing or repairing military damage to the environment, preventing or responding to environmentally caused conflicts, and protecting the environment due to its inherent moral value.
Sécurité humaineLa sécurité humaine est un concept émergent apparu dans les années 1990, qui remet en cause l'approche traditionnelle de la sécurité fondée principalement sur le concept de sécurité nationale. À l'État et ses intérêts, auxquels se réfèrent la « sécurité nationale » et les « intérêts nationaux », le concept de sécurité humaine préfère prendre l'individu comme objet référent (c'est-à-dire comme objet à protéger).
