Three studies explored gender differences in explicit and implicit components of sexual arousal following brief exposure to a sexual stimulus. Whereas Study 1 assessed reports of sexual arousal following subliminal exposure to a sexual or a neutral picture, Studies 2 and 3 examined the effects of the same priming procedure on accessibility of sex-related thoughts assessed with a pictorial judgment task and a lexical decision task. The subliminal sexual prime did not have an effect on men's reports of sexual arousal, but caused women to report lower levels of sexual arousal. In contrast, the same subliminal sexual prime led to higher accessibility of sex-related thoughts in both men and women. It is therefore suggested that the subliminal sexual prime causes women to activate sex-related mental contents but to experience the result as somewhat aversive. 相似文献

A sensitivity analysis displays the increase in uncertainty that attends an inference when a key assumption is relaxed. In matched observational studies of treatment effects, a key assumption in some analyses is that subjects matched for observed covariates are comparable, and this assumption is relaxed by positing a relevant covariate that was not observed and not controlled by matching. What properties would such an unobserved covariate need to have to materially alter the inference about treatment effects? For ease of calculation and reporting, it is convenient that the sensitivity analysis be of low dimension, perhaps indexed by a scalar sensitivity parameter, but for interpretation in specific contexts, a higher dimensional analysis may be of greater relevance. An amplification of a sensitivity analysis is defined as a map from each point in a low dimensional sensitivity analysis to a set of points, perhaps a 'curve,' in a higher dimensional sensitivity analysis such that the possible inferences are the same for all points in the set. Possessing an amplification, an investigator may calculate and report the low dimensional analysis, yet have available the interpretations of the higher dimensional analysis. 相似文献

Animals bring a sense of "at homeness" and even normalcy to people who are hospitalized or live in health care facilities. Illnesses, separation from family, fear, loneliness, and even depression may be lessened for those who receive a therapy dog visit by providing a welcome change in routine and something to look forward to. Individuals are often more active and responsive during and after a visit. Just stroking and petting a dog requires the use of hands and arms, as well as the motions of stretching and turning. Dogs are also unconcerned with age or physical ability; they accept people as they are. This alone causes many to reach out and interact with dogs. Animals provide a focus for conversation and a common interest. As Cocoa's human partner can attest, a pet also makes it easier for strangers to talk. Cocoa is known by so many people at the facilities she visits that residents' family members often stop to talk with "Cocoa's mom" when they meet her in the community, asking questions about how Cocoa is doing. When Cocoa is no longer able to perform her services, many in her community will mourn. Cocoa's story, as well as the limited research literature, supports the positive physical and psychological effects of animals, but continued research on the effect of therapy animals on health outcomes is needed. As advocates for clients, nurses are in key positions to facilitate the inclusion of animals in clients' care. Although not for everyone, including those who react negatively to animals or who are allergic, pet therapy offers important possibilities for providing holistic care that extends not only to clients, but also to family members and staff, and to the pets themselves. 相似文献

Global competition in manufacturing sector demand higher productivity levels. In this context, workers in this sector are set with high output targets, leading to job strain. In addition to the strain, hazardous conditions also prevail in some of the manufacturing processes like foundry activities. This paper attempts to appraise the prevalence of job strain among foundry shop floor workers in India with the help of Demands-Control model [8]. In this study, data was collected through a survey using 49-item Job Content Questionnaire (JCQ) [9], a widely used and well-validated test for job strain. Then the data was subjected to statistical analysis after ascertaining the reliability. This survey has revealed that 25% of workers in foundry were experiencing high job strain. Hazardous working conditions, limited decision making authority, etc. appear to be the main contributing factors for the higher levels of strain. 相似文献

Recent reports suggest that the infectivity of sexually transmitted HIV (i.e., the probability of transmission on a single sexual contact) may be up to 1,000 times greater during the first few months of infection than during the long asymptomatic period that precedes the development of AIDS. Assuming the validity of this estimate, a simple Bernoulli-process model of HIV transmission indicates that, in some cases, the expected number of secondary infections is greater for the brief period of primary infection than for the much longer asymptomatic phase. The implications of these findings for current HIV/AIDS prevention practices are analyzed with particular attention to the role of condom use in preventing HIV transmission. 相似文献
