Stress and Immunity: Age Enhances the Risks

A competent immune response is central to good health. There is good evidence that both aging and psychological stress can dysregulate immune function, resulting in changes in various aspects of the immune response that are large enough to have consequences for health. Older adults appear to show even greater immunological impairments associated with stress or depression than younger adults. Thus, the data suggest that aging interacts with stress and depression to enhance risks for morbidity and mortality among older adults.     

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.     

A Multi‐Source,Multi‐Study Investigation of Job Performance Prediction by Political Skill

Political skill is a social effectiveness construct with a demonstrated capacity to predict job performance. However, because performance prediction research in this area to date has made exclusive use of self‐reports of political skill, and due to frequent distrust of self‐ratings of constructs in important personnel decisions, there is a need to investigate how multiple alternative sources of political skill and job performance measures relate, thus raising both theoretical and methodological issues. In three studies, employing a triadic data collection methodology, and utilising both cross‐sectional and longitudinal designs, this research tested the hypotheses that employee political skill, measured from the perspective of employees' assessor A, will positively predict job performance rated by assessor B (i.e. Hypothesis 1a), and vice versa, that employee political skill measured by assessor B will predict job performance ratings measured by assessor A (i.e. Hypothesis 1b).     

Response to Michael Sells

In an era when lies and misrepresentations about historical events easily become firmly rooted, Michael Sells's discussion illustrates the importance of careful historical research as a moral enterprise. In addition to the skills of the historian, however, there is also room in this enterprise for those of the ethicist. In particular, I warn against confusing the truth or falsity of claims about one narrow historical period with larger questions about the moral meaning and significance of those claims. Illustrating this, I argue one cannot assess the legitimacy of competing nationhood claims solely on the basis of the deeds of specific actors. Nor should the actions of a single individual like the Grand Mufti of Jerusalem be converted into a totalizing claim about the rights of the Palestinian people.
