The temptation to free ride and the fear of exploitation are traditionally offered as factors explaining individuals' choices under conditions of social dilemma. In two experimental studies of prisoner's dilemma behaviour we demonstrate that the ratio-differences of payoffs are as important as the absolute differences in affecting the likelihood of cooperation. The implications of this additional structural determinant of dilemma choice are developed and applied to the stalled gains debate in international relations theory. By incorporating ratio-differences into the analysis 'realist' and 'liberal' theories of state behaviour may be reconciled. 相似文献

We investigated the relation between urban psychosocial stressors and intimacy achievement in a sample of 59 African American, Hispanic American, and White adolescent fathers-to-be. Participants received an intimacy score based on Orlofsky's Intimacy Status Rating Scale. Those with higher cumulative psychosocial stressors had lower levels of intimacy. One psychosocial risk factor, low interpersonal empathy, was significantly associated with intimacy levels. African Americans had lower levels of intimacy than Hispanic or White participants. 相似文献

Several empirical studies have suggested that legislators engage in a surprisingly large degree of on-the-job consumption, or ideological behavior. These findings cast doubt on the hypothesis that legislators can be modelled as though they seek to maximize political support. This paper attempts to determine whether commonly used proxies for ideology in fact represent behavior to which voters are averse. The results show that legislators who engage in more of this behavior lose general-election support without generally receiving compensating increases in partyprimary support. A corollary to this result is that voters punish shirking legislators significantly. 相似文献

The cold war dominated American perceptions of the People's Republic of China during the 1950s and 1960s, and opinions of China were correspondingly negative. Improved Sino-American relations, accompanied by domestic reforms in China, led to a gradual improvement in American attitudes toward China during the 1970s and 1980s. By the late 1980s, Americans held positive perceptions of China and its relations with the United States, but continued to view the People's Republic as communist and undemocratic. This sort of inconsistency is characteristic of periods of cognitive transition: some established perceptions are slower to change than others, and this results in structural imbalance. The Tiananmen Square massacre of June 1989 interrupted this transitional process and sent perceptions of China shooting back toward balanced, cold war stereotypes. The massacre set the Chinese government in a clear symbolic struggle against freedom and democracy. This rekindled latent cold war images of China and elicited disapproving rhetoric from American leaders. The result was a quick reversion to negative perceptions of China, structured by a lingering cold war schema. These processes are demonstrated through the presentation of a study that explores the cognitive structure of perceptions of China both before and after the massacre. 相似文献

There have long been calls for the reduction of coercion in treating civilly committed psychiatric patients. The present study assessed whether a minor procedural change intended to reduce the adversarial nature of the treatment process would have a positive impact. Results suggested that the change in procedure had a positive effect for the most direct outcome variables but results were more mixed for the indirect outcome variables. Nonetheless, overall indications were that the change of procedure affected patient outcome. 相似文献

This analogue study (written vignettes and videotapes) examines the influence of victim-perpetrator relationship (spouse or acquaintance), sex of perceiver, and type of abuse (psychological vs. physical) on attributions about victims and perpetrators of domestic abuse. College student participants (73 men, 108 women) were randomly assigned to condition. As expected, type of relationship influenced observer perceptions. Specifically, participants rated the victim of marital violence as more psychologically damaged and disturbed by the abuse than the victim of acquaintance violence. Furthermore, interaction effects showed that men, more than women, rated the actions of the married perpetrator as more of a victim's rights violation than the actions of the acquaintance perpetrator. Second, type of abuse was shown to influence perceptions of the perpetrator but not the victim. Sex-of-perceiver effects were also obtained. Women held the perpetrator more responsible and assigned less blame to the victim than did men. Legal and clinical implications are then discussed. 相似文献

We reviewed a series of 66 deaths in Washington State between 1995-2000 in which tramadol (Ultram and Ultracet, Ortho-McNeil) was detected in the decedent's blood, in order to assess the role tramadol was determined to have played. Additionally, we reviewed a series of 83 impaired driving cases in which tramadol was detected in order to establish a non-lethal blood tramadol concentration reference range. In both populations, tramadol was consistently found together with other analgesic, muscle relaxant, and CNS depressant drugs. Death was rarely attributable to tramadol alone. However, tramadol may be a significant contributor to lethal intoxication when taken in excess with other drugs, via the potential interaction with serotonergic antidepressant medications, as well as the potential for increased CNS depression. Although the incidence of tramadol detection has increased consistently over the last eight years, there is no evidence of a corresponding increase in the number of cases in which death was attributed solely to tramadol. Blood drug concentrations in many deaths exceeded the therapeutic serum range of 0.28-0.61 mg/L; however, the concentrations overlapped almost completely with the range identified in living subjects arrested for impaired driving. These findings suggest caution in the interpretation of blood tramadol concentrations outside of the recognized therapeutic range. It also suggests that the drug, even when used in moderate excess, is not a principle cause of death in suicidal or accidental deaths. 相似文献

This article profiles self-reported substance use, health, and mental health problems among a sample of incarcerated women in Kentucky as well as lifetime service utilization. Findings indicate that a high percentage of women reported use of alcohol, cocaine, and multiple substances during the month before incarceration. In addition, participants reported common health problems such as dental, female reproductive, physical injuries, and mental health problems including depression and anxiety. Participants reported moderate use of emergency room and mental health treatment but limited substance abuse treatment utilization. Implications for criminal justice programs and linkages with community-based aftercare services for women are recommended based on findings that health and mental health problems are associated with service utilization before incarceration. 相似文献
