Rural men who have sex with men (MSM) have few identifiable venues in which to congregate and meet potential sex partners. The Internet provides a venue for rural MSM to meet, and this is potentially troubling because studies of urban MSM suggest that HIV risk is higher for men who date online. The goals of this study were to identify venues where rural MSM meet their sexual partners and to examine their association with high-risk sexual practices. Six hundred sixty-three predominantly single, gay, Caucasian MSM completed an online survey of their sexual activities. Results showed that the Internet and bars were the most popular venues for meeting sex partners. Highest rates of risk behaviors were associated with Internet dating and venues in which immediate sexual encounters typically occur, suggesting that prevention in rural areas should target multiple-risk environments.  相似文献

The current project tested a diagnostic approach to selecting interventions to increase patron selection of reusable dinnerware in a cafeteria. An assessment survey, completed by a sample of 43 patrons, suggested that the primary causes of wasteful behavior were (a) environmental arrangement of dinnerware options and (b) competing motivational variables. A functional relation between environmental arrangement and reusable product selection was demonstrated in a reversal design. However, the largest effect occurred as function of a multicomponent intervention involving environmental arrangement, employee involvement, and personal spoken prompts with motivational signs. The results support the use of informant assessments when designing community interventions.  相似文献

Experiences with a high emotional content (aversive) tend to be stored as long-term memories; however, there are also contextual recollections, which form a significant part of our memories. Different research has shown that the insular cortex (IC) plays an important role during aversive memory formation, yet its role during incidental/non-aversive learning like pre-exposure contextual memory formation has received little attention. The objective of this research was to establish the role of cholinergic activity in the IC through its muscarinic receptors during the formation of inhibitory avoidance (IA) memory, as well as during pre-exposure contextual memory, using a paradigm such as latent inhibition (LI). Rats with bilateral cannulae directed into the IC were trained in the LI paradigm of IA or IA task alone. The muscarinic antagonist receptor scopolamine was infused bilaterally into the IC 5 min before the pre-exposure into the dark chamber of the IA cage, one day before the conventional IA training or during the IA training day. During the IA test, the entrance latency into the dark chamber of the IA cage was measured as an index of contextual memory. The results showed that scopolamine infused before and after IA training disrupts inhibitory avoidance memory. Also, it showed that the pre-exposed saline-infused animals (LI) had a lower entrance latency compared to the group not pre-exposed (IA). However, the group that received scopolamine into the IC before, but not after, the pre-exposure to the dark chamber, presented a similar latency to the IA group, showing a blockade of the latent inhibition of the IA. These results suggest that cholinergic activity in the insular cortex is necessary during the acquisition and consolidation of avoidance memory, but appears necessary only during the acquisition of pre-exposure non-aversive contextual memory.  相似文献

Computer-mediated communication (CMC) offers its users a reduced-cues environment, a chosen degree of identifiability to others, and a forum to express facets of one's self. Previous research suggests CMC is more appealing than traditional forms of communication to certain individuals whose desires to be sociable with others are prohibited by social inhibitions. The present study predicted that individuals who indicated higher levels of both shyness and sociability would be able to express their true-selves to a greater extent online. Their relationships online would grow more quickly and be more satisfying relative to others. The pattern of results supports our hypotheses, except for the predicted relationship between true-self expression and CMC use. Suggestions for future research as well as implications for the application of CMC use in therapy for certain populations are addressed.  相似文献

This paper challenges a finding reported by several researchers, that fundamentalism could be associated with a reduction in racial prejudice after controlling for authoritarianism (RWA). We argue that the presence of fundamentalism in the construct definition of the conventionalism cluster of RWA leads to higher associations between fundamentalism and conventionalism than with other aspects of RWA. This creates a statistical artefact that distorts the results of multiple regression analyses that include both fundamentalism and RWA as independent variables. To test this hypothesis, 299 participants completed measures of prejudice as well as fundamentalism and the three RWA clusters (conventionalism, authoritarian aggression, and submission). In regression analyses using fundamentalism and the combined RWA scale we replicate previous findings that when RWA is controlled, higher fundamentalism leads to lower prejudice. After removing the overlapping method variance in the scales, this pattern is eliminated and the commonly observed positive relationship between fundamentalism and prejudice is found. We describe the statistical artefact, its antecedents, and its theoretical implications, and outline how investigations in this important area should proceed.  相似文献

Computer-based diagnostic assessment systems hold potential to help teachers identify sources of poor performance and to connect teachers and students to learning activities designed to help advance students’ conceptual understandings. The present article presents findings from a study that examined how students’ performance in algebra and their overcoming of common algebraic misconceptions were affected by the use of a diagnostic assessment system that focused on important algebra concepts. This study used a four-group randomized cluster trial design in which teachers were assigned randomly to one of four groups: a “business as usual” control group, a partial intervention group that was provided with access to diagnostic tests results, a partial intervention group that was provided with access to the learning activities, and a full intervention group that was given access to the test results and learning activities. Data were collected from 905 students (6th–12th grade) nested within 44 teachers. We used hierarchical linear modeling techniques to compare the effects of full, partial, and no (control) intervention on students’ algebraic ability and misconceptions. The analyses indicate that full intervention had a net positive effect on ability and misconception measures.  相似文献

This study reports the explanations of presenting problems given by 10 mothers of children referred to a department of child and family psychiatry and their therapists. Video-recordings of therapists' pre-session meetings and the initial therapy sessions were searched for explanatory statements. These statements were then coded. It was found that therapists referred to past events, present circumstances, relationships, and possible future events in their explanations of presenting problems significantly more frequently than mothers. It was rare for mothers to speak in terms of past or future events at all. The mothers explained difficulties in terms of character traits significantly more often than did the therapists. The implications of these findings are discussed.Thanks to all of the child and family consultation team at 1 Wolverton Gardens for their participation in this research and particularly to Ruth Kossoff for her great help with organising data collection.  相似文献

This study examined coping with homesickness in a sample of homesick adult women. For this purpose, the Adult Homesickness Coping Questionnaire (AHCQ) was constructed. Analysis of the structure of the AHCQ revealed four factors: Social Support, Positive Thinking/Distraction, Turning to Religion, and Mental Escape. The psychometric properties of the AHCQ appeared adequate. Results indicated that ways of coping with homesickness are related to diverse aspects of the homesickness experience, like length of stay in the homesickness situation, causal attributions, and intensity levels of homesickness feelings. It is emphasized that future prospective studies should focus specifically on the (in)effectiveness of coping strategies in order to design adequate interventions for homesick individuals.  相似文献
