The social structure of cooperation and punishment

The standard theories of cooperation in humans, which depend on repeated interaction and reputation effects among self-regarding agents, are inadequate. Strong reciprocity, a predisposition to participate in costly cooperation and the punishment, fosters cooperation where self-regarding behaviors fail. The effectiveness of socially coordinated punishment depends on individual motivations to participate, which are based on strong reciprocity motives. The relative infrequency of high-cost punishment is a result of the ubiquity of strong reciprocity, not its absence.     

The Default Mode Network and Recurrent Depression: A Neurobiological Model of Cognitive Risk Factors

A neurobiological account of cognitive vulnerability for recurrent depression is presented based on recent developments of resting state neural networks. We propose that alterations in the interplay between task positive (TP) and task negative (TN) elements of the Default Mode Network (DMN) act as a neurobiological risk factor for recurrent depression mediated by cognitive mechanisms. In the framework, depression is characterized by an imbalance between TN-TP components leading to an overpowering of TP by TN activity. The TN-TP imbalance is associated with a dysfunctional internally-focused cognitive style as well as a failure to attenuate TN activity in the transition from rest to task. Thus we propose the TN-TP imbalance as overarching neural mechanism involved in crucial cognitive risk factors for recurrent depression, namely rumination, impaired attentional control, and cognitive reactivity. During remission the TN-TP imbalance persists predisposing to vulnerability of recurrent depression. Empirical data to support this model is reviewed. Finally, we specify how this framework can guide future research efforts.     

Rumination mediates the relationship between impaired cognitive control for emotional information and depressive symptoms: A prospective study in remitted depressed adults

Impaired cognitive control may be an important vulnerability factor for depression. Moreover, impairments in cognitive control have been proposed as a crucial process underlying ruminative thinking. The present study investigates the influence of impaired cognitive control for emotional information on rumination and depressive symptoms in a prospective design with a 1 year follow up in a clinical sample. Thirty remitted depressed adults completed the Internal Shift Task (IST), a measure of cognitive control of emotional information, at baseline. Moreover, questionnaires measuring rumination (RRS) and depressive symptoms (BDI-II) were administered. One year later participants were contacted again and asked to complete the BDI-II and RRS. Mediation analyses showed a significant influence of impaired cognitive control for emotional information at baseline on depressive symptoms one year later, which was fully mediated by rumination. These findings underscore the importance of cognitive control abilities as a process underlying rumination and as a vulnerability factor for depression. They can stimulate translational research to improve the effectiveness of interventions that aim to decrease vulnerability by targeting cognitive control.     

Neural Correlates of Reward Processing in Adolescents With a History of Inhibited Temperament

ABSTRACT— Functional imaging data were acquired during performance of a reward-contingency task in a unique cohort of adolescents (ages 14–18 years) who were characterized since infancy on measures of temperamental behavioral inhibition. Neural activation was examined in striatal structures (nucleus accumbens, putamen, caudate) with a known role in facilitating response to salient reward-related cues. Adolescents with a history of behavioral inhibition, relative to noninhibited adolescents, showed increased activation in the nucleus accumbens when they believed their selection of an action would affect reward outcome. Neural responses did not differ between the two groups when participants made a prespecified response that they knew would result in reward or when they produced random motor responses that they knew would not be rewarded. These results link inhibited temperament and perturbed neural responses to reward-contingency cues.     

Using the Black Sheep Effect to reveal normative stakes: The example of alcohol drinking contexts

The present study shows that the paradigm relative to Black Sheep Effect (BSE) may be used to reveal normative stakes whose existence is not clearly identified. To this end, our study focuses on alcohol drinking practices among students, specifically with regard to drinking contexts (solitary vs. group). Our hypothesis was that the drinking norms are determined by their context (i.e. social vs. solitary drinking). More specifically, we suggested that social drinking is viewed by students as pro‐normative, while solitary drinking is viewed as anti‐normative. The results confirmed our hypotheses and enable us to consider that the BSE paradigm has the potential to reveal normative stakes. Copyright © 2010 John Wiley & Sons, Ltd.     

Religion and the Catholic Church’s View on (Heart) Transplantation: A Recent Statement of Pope Benedict XVI and its Practical Impact

Heart transplantation is performed on approximately 4,000 patients per year worldwide and is considered the last resort for treatment of end-stage heart diseases. Due to persistent organ shortage, resources are limited, waiting periods are extensive, and patients still die while being on a waiting list for transplantation. The role of all churches and the support of the representatives of the churches are critical for the spiritual wellbeing of patients awaiting heart transplantation as well as for prospective individual organ donors and their families. The supportive role of the Roman Catholic Church and the recent statement of Pope Benedict XVI on organ donation are discussed.     

Sustaining work force inclusion and well-being of mothers on public assistance: Individual deficit and social ecology perspectives

This study compared theoretical perspectives on the psychological and paid labor activity implications of mandating mothers initially on US welfare to participate in labor force activities. Data were collected that reflected these areas: government public policy interventions, family social ecology measures, mother’s psychological and human capital, and community capital. A quasi-experimental design was used, and multiple source data was collected over time. In the initial part of the study, 144 welfare mothers and one of their children between 9 and 13 years were interviewed. Results indicated that having high levels of individual human and psychological capital and lower levels of family social ecological barriers predicted higher levels of maternal paid labor market activity and psychological well-being. Using archival records, additional analyses involved a 32-month review of state records for nearly 1200 mothers initially on welfare. Results revealed that the lower one’s initial capital—either educational (lacking GED or high school diploma) or community-based (residents spending a high percentage of gross income on rent), the greater one’s economic dependence on public welfare, regardless of whether one was assigned to a welfare to work program or to a control group. Thus, mandating labor market activity as a government public policy was not effective as an isolated strategy to uphold employability over time. These results suggest that employers and government leaders need to provide individual human capital and community capital investments to sustain work force inclusion of low-income mothers.     

向乌托邦告别吗?

存在三种意义上的向乌托邦告别.从前的乌托邦主义者是马克思主义的先行者,但是乌托邦主义者缺乏中间阶段,脱离现实,不善生活.马克思主义并非不是乌托邦,而是一种具体的乌托邦的新事物.具体的乌托邦要求我们善于同可能性打交道,努力领悟可能性,使之成为一种智力参谋部,从而建设一个公正的、美好的、人道的社会.具体的乌托邦永不满足.
