A growing body of evidence suggests that a wide range of animals can recognize and respond appropriately to calls produced by other species. Social learning has been implicated as a possible mechanism by which heterospecific call recognition might develop. To examine whether familiarity and/or shared vulnerability with the calling species might influence the ability of sympatric species to distinguish heterospecific alarm calls, we tested whether four ungulate species (impala: Aepyceros melampus; tsessebe: Damaliscus lunatus; zebra: Equus burchelli; wildebeest: Connochaetes taurinus) could distinguish baboon (Papio hamadryas ursinus) alarm calls from other loud baboon calls produced during intra-specific aggressive interactions (‘contest’ calls). Overall, subjects’ responses were stronger following playback of alarm calls than contest calls. Of the species tested, impala showed the strongest responses and the greatest difference in composite response scores, suggesting they were best able to differentiate call types. Compared with the other ungulate species, impala are the most frequent associates of baboons. Moreover, like baboons, they are susceptible to both lion and leopard attacks, whereas leopards rarely take the larger ungulates. Although it seems possible that high rates of association and/or shared vulnerability may influence impala’s greater ability to distinguish among baboon call types, our results point to a stronger influence of familiarity. Ours is the first study to compare such abilities among several community members with variable natural histories, and we discuss future experiments that would more systematically examine development of these skills in young ungulates.  相似文献

In this paper we discuss and analyze the model of career that has been associated with the academic environment and compare that with past and present career contracts in the corporate environment. We also trace the evolution of the career model in the two institutions. We argue that the recent boundaryless or protean model of the corporate career represents a move toward the original view of the academic as an autonomous professional. And, in turn, it appears that careers in academe have moved toward more of a corporate direction, as universities have become more customer focused and business driven. Implications for these differences and similarities for universities and for corporations are discussed.  相似文献

Atopic dermatitis (AD) is a common and debilitating inflammatory dermatological disorder and is marked by itch and inflamed skin. Scratching, sleep loss, and avoidance of situations associated with more AD symptoms are central hypothesized mechanisms that perpetuate the disorder and cause reduced quality of life. We developed an exposure-based cognitive behavioral treatment (CBT) that entailed mindfulness practice as a means to increase tolerance for aversive experiences during exposure. The aim of the present study was to test the treatment’s acceptability and preliminary efficacy in adults with AD. We used an uncontrolled pretest-posttest design and recruited participants (N = 9) from a university hospital dermatological clinic. The treatment comprised 10 weekly sessions over 10 weeks and assessments of AD symptoms as well as psychiatric symptoms and quality of life were conducted at baseline, posttreatment and 6-month follow-up. The results showed significant and large baseline to posttreatment improvements on self-reported measures of AD symptoms (p = .020) and general anxiety (p = .005), but there was no significant improvement in depression or quality of life. Treatment satisfaction was high and a majority of participants (67%) completed the treatment. We conclude that exposure-based CBT for adult AD can be feasible, acceptable, and potentially efficacious.  相似文献

This study places the reporting of sexual harassment within an integrated model of the sexual harassment process. Two structural models were developed and tested in a sample (N = 6,417) of male and female military personnel. The 1st model identifies determinants and effects of reporting; reporting did not improve--and at times worsened--job, psychological, and health outcomes. The authors argue that organizational responses to reports (i.e., organizational remedies, organizational minimization, and retaliation) as well as procedural satisfaction can account for these negative effects. The 2nd model examines these mediating mechanisms; results suggest that these mediators, and not reporting itself, are the source of the negative effects of reporting. Organizational and legal implications of these findings are discussed.  相似文献

The present study investigates the relationship between self-focused attention and the experience of emotional and bodily concomitants of alcoholic intoxication. It was hypothesized that self-focused attention would amplify salient mood and bodily concomitants of intoxication after alcohol intake and counteract these concomitants after placebo treatment. Self-focused attention was assessed by measures of private body consciousness, private self-consciousness, and of self-awareness. Since alcohol intake did not influence mood, it was not possible to test our main-hypothesis linking self-focused attention with the experience of mood concomitants of intoxication. As to bodily concomitants of intoxication a strong effect of alcohol intake was disclosed. Further analysis revealed the predicted relationship between self-awareness and private body consciousness on one hand and the experience of bodily concomitants of intoxication, on the other. The relationship between private body consciousness and experience of bodily concomitants of intoxication was moderated by the amount of experience with alcohol. No significant relationship between private self-consciousness and experience of bodily concomitants of intoxication was found.  相似文献

While a growing body of literature supports the role of mutual help organizations in helping members achieve abstinence, fellowships other than Alcoholics Anonymous and outcomes beyond abstinence have been studied far less often. The current study examined recovery-related correlates of psychological well-being in a sample of Narcotics Anonymous (NA) members. Participants (N = 128) were self-identified NA members from across the United States who completed an online survey assessing an array of psychosocial outcomes. Hierarchical regression models assessed whether abstinence duration and other recovery-related variables accounted for significant incremental variance in psychological well-being, over and above several covariates. As a block, abstinence duration and the recovery predictors accounted for significant incremental variance in three of four psychological well-being domains. As a complement to studies on short-term benefits of mutual help organizations, these data suggest ongoing recovery involvement may be positively associated with subjective psychological well-being in NA members.  相似文献

The relationship between WISC-R Full Scale IQ and scores on the Woodcock Reading Mastery Tests were explored for 80 developmentally disabled children. While the children's reading skills correlated moderately and significantly with intellectual status, abstract reading skills, e.g., word comprehension, correlated more highly with Full Scale IQ than did concrete ones, e.g., word identification. The development of concrete learning patterns by such children was discussed, with an emphasis on the emotional importance of these learning styles to the children and their families.  相似文献

This study examined the effect of the squad commander's ethnic origin on subordinates' interethnic attitudes. Thirty squads of recruits, serving in the Israeli army, took part in the study. Seventeen of the squad commanders were of Middle Eastern origin, and 13 of Western origin. Each squad contained both Middle Eastern and Western soldiers. Toward the end of the basic training, subjects responded to a series of questionnaires assessing their willingness to share various activities with both squad members and soldiers they did not know, as well as their evaluation of them. The results show- that those serving under a Western commander displayed more willingness to interact with Western than with Middle Eastern others. Subjects serving under a Western commander also evaluated more positively Western than Middle Eastern non-familiar soldiers. Those serving under a Middle Eastern commander displayed more willingness to share activities with Middle Eastern than with Western non familiar soldiers. They also evaluated nonfamiliar soldiers from Middle Eastern origins more positively than Western soldiers. The discussion focuses on the distinction between familiar and non familiar targets, and the role of “equal-status hypothesis” and “expectation states theory.”  相似文献
