We investigated the prevalence of cumulative mild head injury (CMHI) symptoms among college student rugby players pre- and post-season. The players completed a number of neuropsychological tests known to be sensitive to CMHI effects: vocabulary, working memory, motor coordination, and a self-report Post Concussive Symptomology (PCS) checklist. A total of 18 rugby players registered at a South African university were participants (age range 18 to 24 years, SD?=?2.02 years). Data were analysed utilising Fishers Exact Test comparisons of pre- and post-season mean scores. There was significant variability on mean scores between the rugby forwards and backline players in terms of verbal memory and concept formation, cognitive flexibility, working memory, and visual motor-processing speed. Poorer overall scores from the rugby forwards may also be indicative of depression as they reported more insomnia and anger on the PCS than the backline players. 相似文献

Using adaptive structuration theory as a framework [DeSanctis, G., & Poole, M. S. (1994). Capturing the complexity in advanced technology use: Adaptive structuration theory. Organization Science, 5(2), 121–147], we examined the influence of organizational context (competitive versus cooperative) and introductory meeting communication medium (face-to-face versus electronic) on the development of trust and collaborative behaviors of dyads communicating electronically. Based on a sample of 208 senior business students operating in computer-mediated (CM) dyads while performing a strategic decision-making simulation, we found that context, introductory communication medium, and time interacted to influence trust and collaborative behaviors. The pattern of development of trust and collaborative behaviors differed for the same introductory communication medium in different context conditions. Further, the level of trust and collaboration for dyad members in the competitive/electronic introductory meeting condition lagged significantly behind those in the other conditions. The findings suggest that introductory face-to-face interaction plays a more important role in facilitating the development of trust and collaboration in a CM environment when the context is competitive. 相似文献

This study examined the relative weight that hiring managers place on applicants' attractiveness, general mental ability (GMA), and the Big Five personality dimensions in assessing employment suitability for high and low customer contact positions. A sample of 130 managers from 43 hotel properties in the United States and Canada evaluated applicant profiles that varied on these dimensions. The policy capturing results demonstrated that attractiveness does impact employment suitability ratings across positions. However, attractiveness is valued less than GMA and conscientiousness. The attractiveness weight was greater in the evaluation of high customer contact positions, suggesting that attractiveness may be perceived as more job‐relevant for positions where employees interact extensively with people outside the organization. These findings are discussed along with implications for practice and future research attention. 相似文献

The “false-hope syndrome” suggests that unrealistic expectations are responsible for the cycle of repeated failure and renewed efforts at self-change characterizing many self-changers. Our hypotheses were that: (1) committing to a particular self-change task would inflate initial expectations, (2) participants would be unsuccessful relative to their expectations, and (3) more elevated expectations would lead to more negative outcomes. Participants were randomly assigned to either increase their physical activity or reduce their stress through meditating or were assigned to a no-change control group. In accordance with Hypotheses 1 and 2, exercise participants had more positive expectations about their resolutions immediately after committing to them, and both exercise and meditation participants were unsuccessful relative to their expectations. With respect to Hypothesis 3, however, having more positive expectations about one's resolution did not predict a worse outcome. 相似文献

The present study examined the association between high status social positions in early adolescence and both overt and relational aggression. A sample of 234 sixth graders (132 girls, 102 boys) completed peer nominations assessing aggression, social centrality, and coolness. Data analyses were based on all sixth graders who received peer nominations, for a total sample size of 417 students (224 girls, 193 boys). Hierarchical linear modeling was used to examine both within-peer group differences and between-peer group differences. Results indicated relational aggression was related to higher overall social centrality and being nominated as cool even when controlling for overt aggression. Overt aggression appeared to be related to higher overall social centrality and being nominated as cool, but this relationship was much weaker when relational aggression was controlled. Although girls used relational aggression more often and boys used overt aggression more often, the use of relational aggression by either gender was related to membership in high status peer groups and high status within the peer group. Implications of the findings and suggestions for future research are discussed. 相似文献

The Dhammayietra is an annual peace walk in Cambodia that originated at the historic repatriation of refugees in the Thai border camps at the U.N.-monitored transition to democracy in 1992. It situates itself within the discourse and practice of "socially engaged Buddhism" that has gained visibility in Asia and American Buddhism during the last two decades. As Cambodia's particular form of socially engaged Buddhism is marked by refugee return, I will argue that the Dhammayietra's revival of Buddhism in postsocialist Cambodia is only possible because of its transnational formation. Represented as a quintessential Khmer Buddhist response to Cambodia's entrenched conflicts, the networks forged beyond the border of Cambodia have been instrumental in fashioning the face of the Dhammayietra. Though it forges its discursive identity vis a vis the "local" space of the nation, this local space is mobile. Maha Ghosananda's instruction to move "step by step" toward peace reappropriates dangerous mobility—the massive relocations during the Khmer Rouge era, refugee flight, the danger of treading on land fed with mines—and turns walking into a religious act. It is this discursive "move" that loosens the Dhammayietra's ties to the nation and allows it to slip across political and religious borders and ally itself with a diverse network of interfaith peace groups that are its transnational public forum. 相似文献

Three experiments are described that assess 5‐month‐old infants’ processing of addition and subtraction events similar to those reported by Wynn (1992a ). In Experiment 1, prior to each test trial, one group of infants was shown an addition event (1 + 1) while another group was shown a subtraction event (2 ? 1). On test trials, all infants were shown outcomes of 0, 1, 2 and 3. The results seemed to require one of two dual‐process models. One such model assumed that the infants could add and subtract but also had a tendency to look longer when more items were on the stage. The other model assumed that infants had a preference for familiarity along with the tendency to look longer when more items were on the stage. Experiments 2 and 3 examined the assumptions made by these two models. In Experiment 2, infants were given only the test trials they had received in Experiment 1. Thus, no addition and subtraction or familiarity was involved. In Experiment 3 infants were familiarized to either one or two items prior to each test trial, but experienced no actual addition or subtraction. The results of these two experiments support the familiarity plus more items to look at model more than the addition and subtraction plus more items to look at model. Taken together, these three experiments shed doubt on Wynn’s (1992a ) assertion that 5‐month‐old infants can add and subtract. Instead they indicate the importance of familiarity preferences and the fact that one should be cautious before assuming that young infants have sophisticated numerical abilities. 相似文献

Little is known about how schizophrenia might affect how a mother responds to her infant, such as whether responding is reduced or impaired. The aim was to identify, from brief videotaped interactions, whether the responses of mothers with schizophrenia were fewer, less positive, more negative, and more ‘abnormal’ than mothers with affective disorder, and whether their infants (mean age: 15 weeks) lacked activity or initiation to which mothers could respond. Mothers with schizophrenia (N = 14) were as responsive as mothers with affective disorder (N = 31), but they showed markedly low positive responsiveness. Only the schizophrenia group exhibited non-responses as a result of being psychologically withdrawn from the interaction, and abnormal behaviors. Inconsistent to our hypothesis, infants in both groups showed similar levels of activity, initiative and negativity. The findings highlight the need for further research to examine the contribution of maternal response impairments to the developmental vulnerability of this genetically high-risk group. 相似文献

This study examined the relationship of 2 types of workplace flexibility to work-family fit and work, personal, and marriage-family outcomes using data (N = 1,601) representative of employed persons in Singapore. We hypothesized that perceived and used workplace flexibility would be positively related to the study variables. Results derived from structural equation modeling revealed that perceived flexibility predicted work-family fit; however, used flexibility did not. Work-family fit related positively to each work, personal, and marriage-family outcome; however, workplace flexibility only predicted work and personal outcomes. Findings suggest work-family fit may be an important facilitating factor in the interface between work and family life, relating directly to marital satisfaction and satisfaction in other family relationships. Implications of these findings are discussed. 相似文献
