This is an overview of the Transtheoretical Model of Change, a theoretical model of behavior change, which has been the basis for developing effective interventions to promote health behavior change.
An study of 100 teen bloggers from around the United States found that the vast majority use blogs to nurture relationships with their peers and build a sense of community -- rather than to admit misbehavior. This preliminary study suggests that blogging could be used therapeutically to help troubled teens express themselves in positive ways.
Researchers repeatedly discovered primary pharmaceutical contaminants, their metabolites, and transformation products in aquatic ecosystems. Body metabolism may not convert consumed pharmaceuticals to their metabolic elements before excretion. In this case, clinical and industrial wastes ensure their presence in the environment. Nevertheless, conventional wastewater treatment methods are ineffective for removing pharmaceutical wastes. Once in the ecosystem, they alter the physiological response of nontarget exposed aquatic and even terrestrial organisms due to induced toxicity.
