Boues d'épurationLes boues d'épuration (urbaines ou industrielles) sont le principal déchet produit par une station d'épuration à partir des effluents liquides. Ces sédiments résiduaires sont surtout constitués de matière organique (bactéries mortes) de matière organique animale, végétale et minérale humide. Une installation moyenne de gestion des eaux usées produit environ de matière sèche par jour et par habitant. D'une manière générales les eaux usées entrant dans une station d'épuration prennent le nom de « boue ».
Behavioral activationBehavioral activation (BA) is a third generation behavior therapy for treating depression. Behavioral activation primarily emphasizes engaging in positive and enjoyable activities to enhance one's mood. It is one form of functional analytic psychotherapy, which is based on a Skinnerian psychological model of behavior change, generally referred to as applied behavior analysis. This area is also a part of what is called clinical behavior analysis (CBA) and makes up one of the most effective practices in the professional practice of behavior analysis.
Behavior modificationBehavior modification is an early approach that used respondent and operant conditioning to change behavior. Based on methodological behaviorism, overt behavior was modified with consequences, including positive and negative reinforcement contingencies to increase desirable behavior, or administering positive and negative punishment and/or extinction to reduce problematic behavior. It also used Flooding desensitization to combat phobias.
