Signature character strengths can foster health-related outcomes in work and private life, thus being particularly important for endangered occupational groups like physicians. However, situational circumstances need to allow character strengths demonstration (applicability) first to enable their application. Therefore, this study addresses the role of (1) applicability of signature character strengths in work and private life beyond their possession and (2) relationships with well-being, work engagement, and burnout dimensions (emotional exhaustion, depersonalization, and reduced personal accomplishment). Hospital physicians (N = 274) completed an online survey examining their signature character strengths and applicability, well-being, work engagement, and burnout dimensions. The top-five individual signature character strengths were fairness, honesty, judgment, kindness, and love. Hierarchical multiple linear regressions revealed that the possession as well as the applicability of signature character strengths was important in work and private life, but to different degrees. Possessing fairness, honesty, or kindness indicated significant positive relations with subjective well-being, whereas judgment and kindness seemed to negatively interact with reduced personal accomplishment. Hospital physicians’ applicability of fairness, honesty, judgment, and love was particularly essential for their psychological well-being and work engagement, whereas the applicability of fairness (reduced personal accomplishment) and judgment (emotional exhaustion, depersonalization) at work interacted negatively with the respective outcomes. Therefore, creating awareness for individual signature character strengths as well as providing applicability in hospitals and private life could be a promising approach to improve physicians’ well-being and consequently patient care as well as the performance of the health-care system in general.

The original Values in Action Inventory of Strengths (VIA-IS) is an international 240 item validated self-report questionnaire measuring character strengths. A validated and reliable English 120-item short form (VIA-120) is available. However, there is limited information about the psychometric properties of the German VIA-120. This article addresses this gap and reports the reliability, validity and comparability of the German VIA-120 with the German VIA-240 version. Two independent samples were recruited: a general population sample (N = 1073, Sample 1) and a sample consisting of medical students and physicians (N = 685, Sample 2). Internal consistency of the VIA-120-scales ranged from α = .58 (modesty) to α = .87 (spirituality) in Sample 1 and α = .63 (honesty) to α = .90 (spirituality) in Sample 2. Intercorrelations between the scales of the 120-item version and the original 240-Items version (Sample 1) ranged from r = .52 (hope) to r = .89 (prudence). Criterion validity with the Satisfaction with Life Scale (SWLS) and the Brief Inventory of Thriving (BIT) was demonstrated. The comparison of the factor structure between the original and the short form showed a good convergence (Tucker’s Phi .93–.99 Sample 1, .95–.98 Sample 2). Overall, the German VIA-120 was reliable, showed good convergence with the German VIA-240 and thus presents a similar level of validity for the assessment of character strengths. This study provides the first indication that the VIA 120 short form is comparable regarding the validity and reliability of the original VIA 240-item version indicating its potential to be used in large scale research studies.

Rape has been posited to be an outgrowth of male reproductive strategies. Forced copulations may have evolved as a consequence of the low parental investment made by males in producing and raising offspring. We designed a laboratory experiment which paired rhesus macaque males with females in order to assess the influence of intersexual aggression on male sexual activity. Younger and older adult males had comparable levels of sexual behavior, but younger males were more aggressive towards females than were older males. In addition, females threatened younger males more than older males. Male attacks on females did not result in sexual intercourse. On the contrary, a negative correlation existed between male aggression towards females and male success at achieving intromissions. Female aggression towards males appeared to be an effective tactic which reduced the chances of sexual intercourse. We conclude that intersexual aggression acts either as a mechanism of dominance assertion or as a means to increase spatial distance between individuals. These data do not support the idea that rape in humans has an evolutionary foundation derived from male reproductive strategies.  相似文献

James Walsh and Moira McQueen accurately conclude that the early delivery of anencephalic fetuses is morally acceptable, but the reasoning they use to reach that conclusion is flawed. First, the principle of double effect does not require a weighing of good and evil, but rather seeks a sufficient reason for tolerating the physical evil indirectly intended. Second, the principle of double effect requires a clear distinction between physical and moral causality. Third, the Catholic moral tradition will not admit direct and intended killing of the innocent. Rather, early delivery of anencephalic fetuses is permissible because of the pathology associated with delivery of anencephalic fetuses at full term. Thus, the early delivery of an anencephalic infant is acceptable if the purpose of the moral act is avoiding a pathological condition on the part of the mother.  相似文献

Key elements of an expectancy violations (EV) framework are forwarded as a possible organizing framework for understanding how touch functions in interpersonal communication. Central to applying an EV framework to touch is assessing the expectedness, interpretations, and evaluations of touch and its influence on such communication outcomes as evaluations of communicator attractiveness and credibility. To address these considerations, an experiment required participants to engage in dyadic problem-solving discussions during which they were touched or not touched by high-valence (attractive, high status, expert) or low-valence (unattractive, low status, inexpert) confederates. Brief touches by high-valence communicators were less expected than from low-valence communicators but positively evaluated from both. Touch also carried many favorable relational message interpretations, and the combination of touch and high communicator valence generally produced the highest credibility and attraction ratings. Some gender effects emerged, which appeared to moderate touch effects. Results suggest that brief touches among strangers may have positive consequences, especially when initiated by high-valence communicators, for whom they may qualify as positive violations.  相似文献

Summary Rules of inference can be interpreted as rules of (purposive) behavior; in such a case the behaptor consists in accepting a certain statement, called conclusion. The justification of a rule of inference with respect to a given end consists in showing that it is the most efficient method of realizing that end; the meaning of the word “efficient”, and the character of the end, should, of course, be made clear. The article is an attempt at reconstructing a part of the theory of mathematical statistics (the so-called parametric inference) along those lines. It is assumed that the end to be realized by following rules of statistical inference is, broadly speaking, a cognitive one.  相似文献
