Effect of consecutive cooling and immobilization on catecholamine metabolism in rat tissues

The combined effect of two stressor stimuli--cooling and immobilization--acting successively on the sympathetic-adrenaline system was studied experimentally in rats that were cooled for 8 hours at 7 C on the first day and immobilized for 6 hours on the next day. The biochemical and histochemical methods used and the experimental technique involved are described in detail. The following conclusions were formulated: (1) the successive action of cooling and immobilization results in a stronger decrease in the adrenaline and noradrenaline content in the adrenal gland than that which could be due to a simple summation of the cooling and immobilization effects; (2) successive cooling and immobilization are followed by activation of catecholamine synthesis in the adrenal gland; and (3) 1-DOPA administration (45 mg/kg 3 times in 2 days) intraabdominally activated catecholamine synthesis in the adrenal glands in both the control and test animals

Evaluation logics in the third sector

In this paper I provide a preliminary sketch of the types of logics of evaluation in the third sector. I begin by tracing the ideals that are evident in three well-articulated yet quite different third sector evaluation practices: the logical framework, most significant change stories, and social return on investment. Drawing on this analysis, I then tentatively outline three logics of evaluation: a scientific evaluation logic (systematic observation, observable and measurable evidence, objective and robust experimental procedures), a bureaucratic evaluation logic (complex, step-by-step procedures, analysis of intended objectives), and a learning evaluation logic (openness to change, wide range of perspectives, lay rather than professional expertise). These logics draw attention to differing conceptions of knowledge and expertise and their resource implications, and have important consequences for the professional status of the practitioners, consultants, and policy makers that contribute to and/or are involved in evaluations in third sector organization

An examination of the broaden-and-build model of positive emotions in military marriages: an actor-partner analysis

How emotional and cognitive processes combined to produce resilience in military marriages post-combat deployments was examined using the “broaden-and-build model of positive emotions” with 40 military couples. The model suggests that positive emotions expand, and negative emotions impede cognitive processes. Utilizing the Actor-Partner Interdependence Model, the association between positive and negative emotions on insight-causation was examined. Actor and partner effects were found for service members’ positive emotions and spouses’ negative emotions but not service members’ negative emotions and spouses’ positive emotions. Service members’ actor and partner effects were significantly stronger than spouses.’ Clinical and research implications are discussed
