TL;DR: In this article, the authors present explanations for the recovery paradox, discuss moderating factors, and suggest avenues for future research, and conclude that recovery processes actually are impaired when job stressors are high (recovery paradox).

TL;DR: The results of an experiment in which business graduate students provided certainty equivalents and judged various dimensions of the outcome distribution of simple gambles that were played either once or repeatedly for 5 or 50 times are reported.
Abstract: To investigate the effect of time horizon on investment behavior, this paper reports the results of an experiment in which business graduate students provided certainty equivalents and judged various dimensions of the outcome distribution of simple gambles that were played either once or repeatedly for 5 or 50 times. Systematic mistakes in the ex-ante estimations of the distributions of outcomes after (independent) repeated plays were observed. Despite correctly realizing that outcome standard deviation increases with the number of plays, respondents showed evidence of Samuelson's (1963) fallacy of large numbers. Perceived risk judgments showed only low correlations with standard deviation estimates, but were instead related to the anticipated probability of a loss (which was overestimated), mean excess loss, and the coefficient of variation. Implications for future research and practical implications for financial advisors are discussed.

TL;DR: A novel variational approach based on a level set formulation of the Mumford-Shah functional and shape priors that permits to segment multiple independent objects in an image, and to discriminate familiar objects from unfamiliar ones by means of the labeling function.
Abstract: We propose a novel variational approach based on a level set formulation of the Mumford-Shah functional and shape priors. We extend the functional by a labeling function which indicates image regions in which the shape prior is enforced. By minimizing the proposed functional with respect to both the level set function and the labeling function, the algorithm selects image regions where it is favorable to enforce the shape prior. By this, the approach permits to segment multiple independent objects in an image, and to discriminate familiar objects from unfamiliar ones by means of the labeling function. Numerical results demonstrate the performance of our approach.

TL;DR: In this article, a multilevel approach was applied to further elucidate the role of neuropeptide S in the etiology of human anxiety, and the functional NPSR A/T (Asn 107 Ile) variant (rs324981) was investigated for association with panic disorder.
Abstract: Animal studies have suggested neuropeptide S (NPS) and its receptor (NPSR) to be involved in the pathogenesis of anxiety-related behavior. In this study, a multilevel approach was applied to further elucidate the role of NPS in the etiology of human anxiety. The functional NPSR A/T (Asn 107 Ile) variant (rs324981) was investigated for association with (1) panic disorder with and without agoraphobia in two large, independent case–control studies, (2) dimensional anxiety traits, (3) autonomic arousal level during a behavioral avoidance test and (4) brain activation correlates of anxiety-related emotional processing in panic disorder. The more active NPSR rs324981 T allele was found to be associated with panic disorder in the female subgroup of patients in both samples as well as in a meta-analytic approach. The T risk allele was further related to elevated anxiety sensitivity, increased heart rate and higher symptom reports during a behavioral avoidance test as well as decreased activity in the dorsolateral prefrontal, lateral orbitofrontal and anterior cingulate cortex during processing of fearful faces in patients with panic disorder. The present results provide converging evidence for a female-dominant role of NPSR gene variation in panic disorder potentially through heightened autonomic arousal and distorted processing of anxiety-relevant emotional stimuli.

TL;DR: Findings show that modernization and more equal opportunities for women and men do not necessarily lead to parental gender indifference, and on the contrary, they may even result in new sex preferences.
Abstract: It has been argued that a society’s gender system may influence parents’ sex preferences for children. If this is true, one should expect to find no evidence of such preferences in countries with a high level of gender equality. In this article, we exploit data from population registers from Denmark, Finland, Norway, and Sweden to examine continuities and changes in parental sex preferences in the Nordic countries during the past three to four decades. First, we do not observe an effect of the sex of the firstborn child on second-birth risks. Second, we detect a distinct preference for at least one child of each sex among parents of two children. For third births, Danish, Norwegian, and Swedish parents seem to develop a preference for having a daughter, while Finns exhibit a signifiant preference for having a son. These findings show that modernization and more equal opportunities for women and men do not necessarily lead to parental gender indifference. On the contrary, they may even result in new sex preferences.
