One common suggestion for reducing the gap between research and practice is for academics to conduct more of their research in real organizational settings. However, there is considerable skepticism among academics about the willingness of organizations to open their doors to researchers, and among both academics and practitioners about the potential value of doing so. The present study examines how 141 successful academic research projects in real organizations proceeded from start to finish. Our results suggest that organizations may be more open to academic research than is commonly believed, and that most researchers experience few problems with participating organizations. On the other hand, most of the examined projects were not heavily collaborative, and only half of the researchers maintained organizational contact after the research was completed. Based on our findings, we offer suggestions for researchers wishing to do organizational research as well as for their organizational partners. 相似文献

Agency, communion, unmitigated agency (UA), and unmitigated communion (UC) are related to psychosocial health outcomes in nonclinical and medical populations. This study examined the relationship between these personality traits and emotional and interpersonal well-being, as up to 50% of women experience difficulties in psychosocial adjustment after being diagnosed with breast cancer. Seventy-four women newly diagnosed with breast cancer completed baseline assessment measures within 2 weeks prior to their first chemotherapy treatment or at the beginning of their hormonal therapy. Findings indicate that (1) agency and UA are important correlates of emotional and interpersonal adjustment and should be considered when attempting to identify women at high risk for psychosocial distress, and (2) UC deserves increased attention in behavioral medicine research, given its strong relationship with emotional distress in a breast cancer population. Thus, evidence continues to accumulate regarding the important relationship of these personality traits to psychosocial outcomes in medical populations. 相似文献

Female, male, and mixed-sex dyads in which one member was assigned the leader role interacted and rated their own dominance throughout the interaction. The effects of gender and romantic attachment status (whether one has an exclusive dating partner or is “unattached” and free to go out with someone new) upon these self-ratings of dominance within the interaction were examined. The results showed that both leaders and subordinates perceived female leaders to be less dominant than male leaders. In addition, members of mixed-sex pairs rated themselves as less dominant than did those in same-sex pairs. Female leaders paired with males rated themselves least dominant and unattached female leaders interacting with males rated themselves least dominant of all. Female subordinates rated themselves as less dominant when with male leaders than when with female leaders, while the effect of the gender of the leader was insignificant for male subordinates. The results are discussed as evidence of a role conflict created by the contradictory roles of “dominant” leader and “subordinate” female, roles described by the sex role stereotypes prevalent in our culture. 相似文献

Reinforcement and the organization of behavior in golden hamsters: Pavlovian conditioning with food and shock unconditioned stimuli 总被引:1,自引:0,他引:1
The effects of Pavlovian conditioned stimuli (CSs) for food or shock on a variety of behaviors of golden hamsters were observed in three experiments. The aim was to see whether previously reported differences among the behaviors produced by food reinforcement and punishment procedures could be accounted for by differential effects of Pavlovian conditioning on the behaviors. There was some correspondence between the behaviors observed to the CSs and the previously reported effects of instrumental training. However, the Pavlovian conditioned responses (CRs) alone would not have predicted the effects of instrumental training. Moreover, CRs depended to some extent on the context in which training and testing occurred. These findings, together with others in the literature, suggest that the results of Pavlovian conditioning procedures may not unambiguously predict what system of behaviors will be most readily modified by instrumental training with a given reinforcer. 相似文献

The study described the abilities of a group of 10 aphasics and 10 normals to produce narrative and procedural discourse. The experimental tasks included telling stories, producing summaries, giving morals to the stories, and producing procedures. The variables examined in the investigation included features of sentential grammars, such as amount of embedding, and features of discourse grammars, such as occurrence of elements of superstructure in narrative. Additionally, raters assessed the content and clarity of the discourses. The results showed that aphasics produced well-structured narrative and procedural discourse. Aphasics' discourse errors differed only in degree, not qualitatively, from those of normals. The language of the aphasics' discourses was reduced in both complexity and amount. It was found that the aphasics had difficulties in producing summaries and giving morals for the stories when compared with the normals. Both the content and clarity of the discourses produced by the aphasics were rated lower than those produced by the normals. 相似文献

Experimentally naive rats can learn rapidly to discriminate among three odors to obtain food reinforcement. After three massed trials, they show almost errorless performance. This task has proved to be useful in studying time-dependent postacquisition intracellular processes necessary for long-term memory. The present experiments evaluated the temporal dynamics of the role of β-noradrenergic receptors in long-term consolidation. Rats were implanted with intracerebroventricular cannulae and trained in a single session to find reinforcement in a hole in a sponge impregnated with a particular odor. Injections of the β-receptor antagonist timolol were made at 5 min, 1, 2, or 5 hr after training. Memory and relearning ability were evaluated 48 hr later. Rats treated with timolol 2 hr after training showed a memory deficit at the retention test, but were able to relearn the task normally. Injections at the earlier or later time points were ineffective. The results reinforce previous observations with systemic injections that β-noradrenergic receptors are involved in the late phase of memory consolidation and suggest a critical time window during which they are necessary. The time window is compatible with the current view that long-term memory depends on late involvement of the cAMP cascade leading to new protein synthesis necessary for synaptic reorganization. 相似文献

This study evaluates the relationship between the social climate from different services and the personal goal-directed activities of 224 individuals with AIDS. The study's results supported the main hypothesis that recipient and participatory service involvement uniquely influence personal goal-directed activities, even after considering individuals with AIDS' physical symptoms, psychological distress, income, and recruitment site. Income and involvement with participatory services were both positively related to the amount of personal goal-directed activity. Longitudinal analyses suggest that personal initiative contributes to the subsequent amount of personal goal-directed activities a person pursues. These results suggest further examination of factors contributing to the selection of different service types and of the processes underlying the relationship between participatory services and positive outcomes for clients with AIDS. 相似文献
