EBERHARD BETHGE: INTERPRETER EXTRAORDINAIRE OF DIETRICH BONHOEFFER

Bethge was Dietrich Bonhoeffer's closest friend and confidant during the last ten years of Bonhoeffer's life. Bonhoeffer held him in high esteem, and he regarded no one better able to understand and clarify his thought. Anticipating his own death, Bonhoeffer designated Bethge to care for his legacy and write his biography, responsibilities Bethge later fulfilled with remarkable dedication and erudition. In the process he produced a significant number of interpretative essays, becoming internationally respected for his historical and theological scholarship, as well as his own engagement with church and social issues. Without Bethge, Bonhoeffer's legacy would not have become as well or as widely known as it did, or interpreted in the way that it has.     

Examining the effects of frustration on working memory capacity

The present study attempts to expand our understanding of frustration, clinical symptoms, and working memory by examining the unique contribution of attention-deficit/hyperactivity disorder symptoms and frustration to working memory capacity (WMC). A factor-analytic framework was utilized to isolate and examine WMC based on results from three working memory tasks that were administered in counterbalanced order to control for individual differences in baseline WMC. All participants provided subjective ratings of frustration both prior to and after administration of a frustration induction. Results suggest that although we were able to systematically induce subjective frustration for participants in the experimental group relative to the control group, WMC was not associated with induced frustration in the present study. Results also indicated that inattention symptoms predicted baseline frustration levels. This work highlights the need to examine the extent to which storage/rehearsal WMC and additional process-oriented working memory-related performance variables are related to frustration. The data that support the findings of this study are available from the corresponding author upon request.     

Risk,cost-effectiveness and profit: Problems in cardiovascular research and practice

Risk is the probability that within a certain time some expected negative event will take place. In medicine risk can be related to a decision or to some intrinsic factors which are associated with the probability of the occurrence of a disease. Decisions can be necessary in the individual life with respect to the question of visiting a physician or performing a certain diagnostic or therapeutic procedure. The introduction of new pharmaceutical or technical products into medical use are another set of decisions which can generate certain risks. Intrinsic or inherent risk factors are a set of variables or signs and symptoms which indicate the presence of a certain probability that some disease or event, e.g., arteriosclerosis or sudden infant death syndrome, may occur. Risk is always related to judgement. In a decision process cost, effectiveness and profit can be used to estimate the magnitude of the risk to be taken. In a similar way the problems in connection with an inherent risk are primarily related to the recognition of the magnitude of risk and to the possibility of prophylactic measures. In our own area of research, the sudden infant death syndrome (SIDS) is an event where only risk factors can be observed. We point at two facts in this context: Highly complex patterns of symptoms like behaviour can better be classified by intuitive Gestalt perception. A medical procedure like induction of labour can itself become a risk factor.     

Intracerebroventricular injection of anti-prolactin serum suppresses excessive grooming of pituitary homografted rats

Rats with endogenous hyperprolactinaemia, as induced by pituitary homografts under the kidney capsule, displayed increased grooming behavior as compared to that of sham-operated animals. Twelve days after surgery, intracerebroventricular injection of anti-prolactin serum (dilution 1:100, 1 microliter) suppressed the excessive grooming of homografted rats. These observations suggest that prolactin from a peripheral source may reach the central nervous system to affect brain mechanisms involved in grooming behavior.
