The aim of this study was to explore the association between the consumption of sexually explicit media (SEM) depicting condom and non-condom use and HIV/STI-related sexual risk behavior among men who have sex with men (MSM) in Norway. We also explored whether the association between SEM consumption and STI-related sexual risk behavior is mediated by men’s sexual self-esteem and/or condom use self-efficacy. A cross-sectional online survey study was carried out in Norway in 2012. The final sample comprised 529 MSM in Norway. There was a bivariate association between the use of SEM picturing condom use and less STI-related sexual risk behavior. Further, the association between SEM consumption and sexual risk behavior was mediated by condom use self-efficacy. However, SEM did not influence sexual risk behavior via sexual self-esteem. The results offer important cross-cultural validation of recent comparative data from the US and may be used to promote HIV/STI prevention, in the sense that the actors in SEM may serve as role models in managing condom use in sexual contexts.  相似文献

Visual working memory is a volatile, limited-capacity memory that appears to play an important role in our impression of a visual world that is continuous in time. It also mediates between the contents of the mind and the contents of that visual world. Research on visual working memory has become increasingly prominent in recent years. The articles in this special issue of Attention, Perception, & Psychophysics describe new empirical findings and theoretical understandings of the topic.  相似文献

The Second Vatican Council’s constitution Gaudium et Spes stated that man is ‘the only creature on earth that God has willed for its own sake’. Post-conciliar Catholic teaching on the environment largely reproduced this anthropocentric theology. Pope Francis’ encyclical letter Laudato Si’, however, appears directly to contradict this well-established tradition with its repeated assertions of the intrinsic value of nonhuman life and its critical approach to the term ‘anthropocentrism’. Questioning this putative discontinuity, this article challenges the perception that Laudato Si’ has definitively rejected anthropocentrism. It suggests that the claim for the intrinsic value of nonhuman life, and the traditional assertion that man is the only creature willed for its own sake, can be seen to converge in light of the traditional theological anthropology of the human being as microcosm. On this view, the centrality of the human person in the order of creation is constituted by its gathering up of the sakes of creatures. The distinctive place of the human does not come at the expense of the rest of creation, but rather is the means of creation’s movement towards the unity and harmony to which God calls it. Laudato Si’ is distinguished not by its rejection of anthropocentrism, but by its refusal to set human and nonhuman over against one another. In contrast, the language of ‘intrinsic value’ is criticised for conceiving created value as a zero-sum game, as though human and nonhuman value are in competition with one another; the language of ‘stewardship’ is criticised for its extrinsicist conception of the human being in the natural order.  相似文献

Organizations often communicate seemingly paradoxical strategic imperatives to their employees that reflect a focus on promotion (take risks) and prevention (be prudent), as outlined by regulatory focus theory. When consistently emphasized and reinforced in an organization, these strategic inclinations can emerge as divergent climates for promotion and prevention that cloud the organization's perceived identity and reduce collective organizational commitment among employees. With a coherent organizational identity acting as both a sensemaking tool and a means of potential self-enhancement for employees, we use social identity theory to hypothesize that similarly emphasized promotion and prevention climates are negatively related to employees’ collective organizational commitment and indirectly, negatively related to organizational productivity. We test our hypotheses in a sample of 107 manufacturing organizations, using polynomial regression with response surface analysis to examine how similarly emphasized promotion and prevention climates relate to collective commitment and organizational productivity. Our analyses reveal that as organization-level promotion and prevention climate scores became more similar, collective organizational commitment decreases. Furthermore, we find that similarly emphasized promotion and prevention climates are negatively related to organizational productivity via collective commitment. We reconcile these findings with the organizational paradox and ambidexterity literatures and implicate promising avenues for future research.  相似文献

Motor learning has been linked with increases in corticospinal excitability (CSE). However, the robustness of this link is unclear. In this study, changes in CSE associated with learning a visuomotor tracking task were mapped using transcranial magnetic stimulation (TMS). TMS maps were obtained before and after training with the first dorsal interosseous (FDI) of the dominant and nondominant hand, and for a distal (FDI) and proximal (biceps brachii) muscle. Tracking performance improved following 20 min of visuomotor training, while map area was unaffected. Large individual differences were observed with 18%–36% of the participants revealing an increase in TMS map area. This result highlights the complex relationship between motor learning and use-dependent plasticity of the motor cortex.  相似文献

A confession is one of the most impactful pieces of evidence that can be presented in a criminal trial, yet very little is known about how perceptions of evidence change based on characteristics of the confession. While researchers know that “circumstances of the setting”, such as length of interrogation, number of interrogators, and lack of sleep, increase the likelihood of false confessions, less is known about whether juror perceptions of the confession are impacted by these factors. The current research builds on the existing literature by evaluating the impact of these situational confession factors to determine whether jurors give weight to characteristics that are known to increase the likelihood of a false confession. Two experimental surveys were conducted, one using a sample of undergraduate students and one using a sample of jury‐eligible adults, in order to determine how respondents perceived a confession's strength. Results showed that confessions arising from lengthy interrogations were perceived to be weaker than those arising from short interrogations. However, multiple interrogators and a lack of sleep had little impact on evidence perceptions; these factors indicate a questionable confession to experts, but not to jurors. The implications for criminal justice theory, criminal trials, and future research are discussed.  相似文献
