The present study examined how different types of social support differentially moderated the relationship between trauma history characteristics and the development of posttraumatic stress disorder symptoms (PTSS) following a motor vehicle accident (MVA). Two hundred thirty-five MVA victims self-reported levels of social support and trauma history, and were evaluated for PTSS 6- and 12-months post-MVA. Results indicated that after controlling for gender, injury severity and income, number of prior trauma types and subjective responses to prior traumatization predicted subsequent PTSS (ps < .05). Appraisal social support was a significant moderator of the total number of types of trauma (appraisal: 6-months β = -.16, p < .05; 12-months β = -.17, p < .05) and subjective physical injury during the prior trauma (appraisal: 6-months β = -.14, p < .05; 12-months β = -.19, p < .05) in predicting PTSS. Results underscore the importance of examining both trauma history and social support as multi-dimensional constructs and suggest merit to addressing social support in trauma victims with a prior trauma history.  相似文献

We conducted 2 studies to determine whether dense and thin NCR schedules exert different influences over behavior and whether these influences change as dense schedules are thinned. In Study 1, we observed that thin as well as dense NCR schedules effectively decreased problem behavior exhibited by 3 individuals. In Study 2, we compared the effects of 2 NCR schedules in multielement designs, one with and the other without an extinction (EXT) component, while both schedules were thinned. Problem behavior remained low as the NCR schedule with EXT was thinned, but either (a) did not decrease initially or (b) subsequently increased as the NCR schedule without EXT was thinned. These results suggest that dense schedules of NCR decrease behavior by altering its motivating operation but that extinction occurs as the NCR schedule is thinned. The benefits and limitations of using dense or thin NCR schedules are discussed.  相似文献

Bridging the literatures on social dilemmas, intergroup conflict, and social hierarchy, the authors systematically varied the intergroup context in which social dilemmas were embedded to investigate how costly contributions to public goods influence status conferral. They predicted that contribution behavior would have opposite effects on 2 forms of status-prestige and dominance-depending on its consequences for the self, in-group and out-group members. When the only way to benefit in-group members was by harming out-group members (Study 1), contributions increased prestige and decreased dominance, compared with free-riding. Adding the option of benefitting in-group members without harming out-group members (Study 2) decreased the prestige and increased the dominance of those who chose to benefit in-group members via intergroup competition. Finally, sharing resources with both in-group and out-group members decreased perceptions of both prestige and dominance, compared with sharing them with in-group members only (Study 3). Prestige and dominance differentially mediated the effects of contribution behavior on leader election, exclusion from the group, and choices of a group representative for an intergroup competition. Taken together, these findings show that the well-established relationship between contribution and status is moderated by both the intergroup context and the conceptualization of status.  相似文献

A peer instruction model was used whereby 78 residence dons (36 males, 42 females) provided instruction regarding academic integrity for 324 students (125 males, 196 females) under their supervision. Quantitative and qualitative analyses were conducted to assess survey responses from both the dons and students regarding presentation content, quality, and learning. Overall, dons consistently identified information-based slides about academic integrity as the most important material for the presentations, indicating that fundamental information was needed. Although student ratings of the usefulness of the presentations were middling, students did indicate knowledge gains. Both interest and personal value for academic integrity were highly predictive of positive evaluations of the presentations. Dons and students provided suggestions for improvement and identified more global concerns.  相似文献

This case study examines the failure of top management at Putnam to exercise ethical behavior in the face of their clear knowledge of corruption in the company. Market timing by employees was expressly forbidden by Putnam. Six employees, including two portfolio managers, repeatedly engaged in market timing activities from 1998 to 2003, garnering over a million dollars in personal profit. The CEO and key senior executives had factual knowledge of the abuses. Management failed to stop the abuses or to discipline those involved until faced with charges from government regulators. By failing to do so, top management breached ethical duties to its shareholders and inflicted serious damage on the organization. The end results of top management's failure to address ethical violations were significant outflow of assets from Putnam's funds, payment of penalties, and loss of trust among investors. This case raises awareness about ethical issues surrounding mutual fund trading practices and the impact that top management can have on the ethical behavior of employees.  相似文献

This article presents three cases of how Lutheran groups used photography as a spiritual practice in processes that led to group spiritual reflection for faith formation and worship: a photography club; a Photography as a Spiritual Practice mini‐course in a parish; and a six‐month parish project of communal art‐making of liturgical media art for one church's Easter Vigil readings.  相似文献

Several critical neuroanatomical structures and pathways for memory performance are located in the third ventricle region. This led us to predict that verbal memory abilities would be more impaired in children treated for third ventricle tumors compared to those treated for cerebellar tumors. Archival data was obtained from 24 pediatric patients with third ventricle region tumors and 18 pediatric patients with cerebellar tumors. Neuroradiological verifications of tumor involvement and hydrocephalus severity (i.e., Evans Index) on preoperative scans and MRIs proximal to the time of the neuropsychological evaluation were conducted. The potential confounds of hydrocephalus severity, seizure medication, age, radiation treatment, and chemotherapy were addressed. Verbal IQ was comparable between tumor groups and in the Average range. The third ventricle region group performed significantly worse on list learning and delayed list recall compared to the cerebellar group. Their mean performance was in the clinically impaired range on both trials. The third ventricle region tumor group performed better than the cerebellar tumor group on Digit Span, a basic repetition, attention span task. These findings support the hypothesis that pediatric patients with third ventricle region brain tumors are more likely to be impaired on verbal recall tasks compared to pediatric patients with cerebellar brain tumors. In contrast, patients who were treated for cerebellar tumors were more impaired on the basic repetition, attention span task compared to patients who were treated for third ventricle tumors. Future studies should examine the specific neuroanatomical structures and pathways that are damaged and may influence differential cognitive impairments in children.  相似文献
