Managing Equality in Social Dilemmas: Emotional and Retributive Implications

The equality rule is an important coordination rule in symmetric public good dilemmas. Although prior research emphasized that people use the equality rule out of efficiency concerns (as it helps to obtain the public good in the most efficient manner among group members), it may also reflect a true preference for fairness. More precisely, research examining emotional and retributive reactions as a result of a violation of the equality rule by a fellow group member showed that equality indeed is related to people’s personal values and what they consider to be fair. The present paper suggests that a violation of the equality rule results in emotional reactions, and these emotional experiences encourage further retributive actions. The different reactions following an equality violation are described as a function of three features: (1) the motives to use equality, (2) attributions for explaining the violation, and (3) the honesty of the given explanation.

Noneconomic Motives Predicting Cooperation in Public Good Dilemmas: The Effect of Received Respect on Contributions

The present research examined the extent to which feeling respected, versus feeling disrespected, influences people's willingness to contribute to the public good. Further, it was investigated why such a positive effect of respect should occur. The findings showed that respect indeed had a positive influence on contributions. In addition, it was shown that respect also positively influenced people's feelings of belongingness and that this feeling was found to mediate the effect of respect on contributions. These findings thus indicate that research on social decision-making, and more specifically social dilemmas, has to start devoting more attention to people's noneconomic motives that are independent of outcome concerns when explaining the act of cooperation.     

Atypical ventricular septal defect

A case of a congenital cardiac malformation in form of a single ventricular septal defect is reported and histopathologic findings are presented. The possible origin with regard to its untypical localisation is discussed.     

Forensic medicine and morphologic aspects of fatal amniotic fluid aspiration

The massive aspiration of amniotic fluid as one cause of a fatal postpartal asphyxia will be demonstrated under the aspect of preliminary criminal law proceedings against physicians because of medical negligence. The pathomorphologically established diagnosis of a fatal aspiration of amniotic fluid supposes extensive and systematic quantitative histological examination of both lungs. The technique of histological cross sections through the entire lung combined with morphometry is a suitable method to exactly record the alterations of bronchi and lung parenchyma by aspiration of amniotic fluid and their complications, such as interstitial emphysema.     

Social Utility in Ultimatum Bargaining

In this article we will provide an overview of factors that influence the weight that self-interest and equity related motives receive in ultimatum bargaining. These factors are grouped into three main categories: factors relating to the context of the game, factors relating to the parties involved, and factors related to characteristics of the game. Results of the studies are discussed in relation to the concept of social utility. The authors point out possible omissions in the literature—especially the lack of interest for the behavior of recipients—and recommend directions for future research.     

Forecasting Errors in the Averseness of Apologizing

Apologizing is often seen as the appropriate response after a transgression for perpetrators. Yet, despite the positive effects that apologies elicit after situations of conflict, they are not always delivered easily. We argue that this is due—at least in part—to perpetrators overestimating the averseness of apologizing, thus committing a forecasting error. Across two laboratory experiments and one autobiographical recall study, we demonstrate that perpetrators overestimate the averseness they will experience when apologizing compared to the averseness they experience when they actually apologize. Moreover, we show that this effect is driven by a misconstrual of the effects of an apology. Perpetrators overestimate the potentially negative effects of apologizing while simultaneously underestimating the potentially positive effects of apologizing. This forecasting error may have a negative effect on the initiation of the reconciliation process, due to perpetrators believing that apologizing is more averse than it actually is.     

Conceiling the cadaver in masonry and cement

Encasing with concrete and/or bricks are relatively rare forms of hiding or disposing of a body; criminologically, cases of this kind are often treated as "matters involving a missing person" at first. The article describes the circumstances and findings of 2 cases in which bodies were encased with concrete. Under the aspects of reconstruction it is of importance that bodies may be preserved quite well in concrete, which allows not only identification of the victim but also determination of the cause of death even after a prolonged post-mortem interval, the more so as occasionally tools used for committing the offense are also encased together with the body.     

Selective detection of cytomegalovirus by in situ hybridization

In two SIDS autopsy cases, in situ hybridization with biotin-labeled DNA probes was used to demonstrate a specific cytomegalovirus (CMV) infection in paraffin-embedded tissue sections. This technique represents a rapid, specific, and highly sensitive tool for the detection of CMV infections and is recommended for routine examination in other suspected viral infections, particularly in cases connected with SIDS.     

The Self-Relevant Implications of Distribution Rules: When Self-Esteem and Acceptance Are Influenced by Violations of the Equity Rule

Based on the assumption that distribution rules may have similarities to procedures, the present research examined the extent to which a violation of the equity rule can influence feelings of self-esteem and acceptance as a function of people's social value orientation (i.e., prosocial vs. proself orientation) and attributional explanation (internal vs. external). In a scenario study, participants imagined that they received a similar financial reward as their task partner, but this partner, however, put less effort into the task (i.e., violation of the equity rule). Results showed that this unfair outcome negatively influenced people's feelings of self-esteem and acceptance, but only among those with a proself orientation and when an internal explanation was given for differences in input.     

When Do People Find Cooperation Most Justified? The Effect of Trust and Self–Other Merging in Social Dilemmas

On the basis of goal/expectation theory, it was predicted that just as in interpersonal relationships, cooperation in social dilemma groups would increase only if both trust was high and group members had a common goal of cooperation. Introducing new measures of both these two processes to the social dilemma arena, the goal of mutual cooperation was assessed by the process of self—other merging (the IOS scale), and trust by assessing the extent to which one trusted others and one believed one was perceived as trustworthy by the others. The results showed that when both self—other merging and trust was high, cooperation was indeed highest. Implications for the specific functions of trust and self—other merging in social dilemmas are discussed.
