This paper reports the results of a qualitative analysis of semi‐structured interviews with 79 members of the Birmingham Untreated Heavy Drinkers Cohort. The cohort was recruited in 1997 when all participants were drinking 50 or more standard units of alcohol (men) or 35 or more units (women) most weeks. Present interviews were carried out as part of the fourth wave of interviews, held in 2003. The topic was the participants' places of drinking in the community and the functions those places served. The present analysis focused on the relationship between pubs and community. The strongest theme to emerge was that the pub provided for many participants a real sense of community in itself. It did so by enabling participants to meet with like‐minded others, in a setting distinct from home or work, where conversing and confiding could take place in a relaxed atmosphere, with a range of other activities and forms of social support available to many. At the same time, participants were discriminating about which pubs they used, and when, and with whom they chose to interact. There was less consensus about whether the pub served a wider function by contributing to a positive sense of community in the local neighbourhood. It is suggested that English pubs, at least in a large conurbation such as the West Midlands, are very varied, sometimes continuing to serve as ‘the local’ for a community, sometimes being part of a variety of drinking places which between them provide people with a diversity of social niches to meet their increasingly diverse choices and preferences, and sometimes reflecting and even contributing to local community disorganisation.

The number of studies examining visual perspective during retrieval has recently grown. However, the way in which perspective has been conceptualized differs across studies. Some studies have suggested perspective is experienced as either a first-person or a third-person perspective, whereas others have suggested both perspectives can be experienced during a single retrieval attempt. This aspect of perspective was examined across three studies, which used different measurement techniques commonly used in studies of perspective. Results suggest that individuals can experience more than one perspective when recalling events. Furthermore, the experience of the two perspectives correlated differentially with ratings of vividness, suggesting that the two perspectives should not be considered in opposition of one another. We also found evidence of a gender effect in the experience of perspective, with females experiencing third-person perspectives more often than males. Future studies should allow for the experience of more than one perspective during retrieval.  相似文献

Discovery of mutations in the breast and ovarian cancer susceptibility genes BRCA1 and BRCA2 can have emotional consequences for both the tested individual and his or her relatives. This secondary analysis study investigated how BRCA testing impacts family dynamics and relationships. For the original study, a grounded theory inquiry, participants were recruited from a hereditary breast/ovarian cancer syndrome support website and open-ended interviews were performed asking about individual and family experiences after BRCA testing. All 12 participants whose interviews were included in the secondary analysis had a BRCA mutation. For the secondary analysis, thematic analysis was conducted and revealed three main themes characterizing the effect of BRCA testing on family relationships: 1. That the first in the family to have testing or seek genetic counseling takes on a special family role that can be difficult for them; 2. That discussions in the family often change; and 3. That individuals may feel more or less connected to certain family members. These changes seemed to relate to family cancer history, relationships, coping strategies, communication patterns, and mutation status. Genetic counselors might find it useful to explore these issues in order to prepare clients before BRCA testing and to support them through shifts in family dynamics after disclosure of results.  相似文献

Participants’ eye movements were monitored while they read sentences containing biased homographs in either a single-meaning context condition that instantiated the subordinate meaning of the homograph without ruling out the dominant meaning (e.g., “The man with a toothache had a crown made by the best dentist in town”) or a dual-meaning pun context condition that supported both the subordinate and dominant meanings (e.g., “The king with a toothache had a crown made by the best dentist in town”). In both of these conditions, the homographs were followed by disambiguating material that supported the subordinate meaning and ruled out the dominant meaning. Fixation times on the homograph were longer in the single-meaning condition than in the dual-meaning condition, whereas the reverse pattern was demonstrated for fixation times on the disambiguating region; these effects were observed as early as first-fixation duration. The findings strongly support the reordered access model of lexical ambiguity resolution.  相似文献

The effects of multimedia instructional materials on map learning and subsequent navigation were examined. Participants studied visual and/or verbal driving directions presented simultaneously, sequentially, or exclusively. Memory recall for the studied information was tested, and participants then attempted to navigate the studied routes as well as a novel route in a driving simulator. Dual modality materials with oral narrative directions and a visual map produced significantly superior performance for recall, navigational accuracy, and number of destinations reached than presentation in either modality alone. The presence of a map facilitated route recall but not subsequent ability to navigate routes in the simulator. Map-first dual modality sequential presentation enhanced wayfinding efficiency on the novel route compared to narration-first sequential presentation. Simultaneous presentation of dual modality materials allowed more destinations to be reached compared with sequential presentation. The results demonstrate that multimedia instructional materials can facilitate map learning and driving navigation, extending the applications of multimedia learning theory to this novel domain.  相似文献

ObjectivesThe purpose of this study was to examine direct, indirect, and moderating links between facet-level personality traits of the five-factor model, the theory of planned behavior (TPB) constructs [Ajzen, I. (1991). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50, 179–211.], and exercise behavior.DesignCross-sectional.MethodUniversity students (N = 507) completed the NEO-PI-R [Costa, P. T., McCrae, R. R. (1992). The NEO-PI-R personality inventory: Professional manual. Odessa, FL: Psychological Assessment Resources.], the Leisure-time Exercise Questionnaire [Godin, G., Shephard, R. J. (1985). A simple method to assess exercise behavior in the community. Canadian Journal of Applied Sport Science, 10, 141–146.], and measures assessing the TPB constructs.ResultsPreliminary analysis revealed the extraversion and conscientiousness facet-level traits of activity and self-discipline respectively were independent predictors of exercise behavior. An integrated structural model with both facet-level traits revealed that 46% of the variance in exercise behavior and 70% of the variance in intention was explained. Significant indirect effects of activity and self-discipline and the TPB constructs of affective attitude, instrumental attitude, and subjective norm, on exercise behavior through intention and perceived behavioral control were also observed. Finally, the anxiety facet trait of neuroticism significantly moderated the intention–behavior relationship.ConclusionsOur findings showed that the facet-level personality traits of activity and self-discipline are important motivational variables that link the TPB constructs to exercise behavior. Future research that integrates personality with the TPB within experimental interventions is warranted.  相似文献

Women who associate with gay men are often portrayed as physically unattractive and lacking in both self-confidence and attention from straight men. However, many women report enhanced self-esteem and feelings of attractiveness as a result of attention from their gay friends. It is well established that body esteem can be negatively impacted by certain peer processes, yet there is a dearth of quantitative research on positive peer influences on women's body esteem. We tested two hypotheses: (a) women with gay male friends have poor body esteem and are rejected by heterosexual men, and (b) more contact with gay men is positively related to body esteem. Participants were 154 heterosexual women, who completed measures of their friendships with gay men, straight men and women, body esteem, relationship involvement and break-ups. Results supported the hypothesis that women's body esteem, specifically feelings of sexual attractiveness, is positively associated with friendships with gay men.  相似文献

Family history information comprises an important tool in identifying and referring patients at risk for hereditary breast and ovarian cancer (HBOC) to cancer genetic counseling. Despite recommendations and support provided by numerous professional organizations, cancer genetic counseling services are underutilized by atrisk patients. This study aimed to: (1) determine the rate of genetic counseling utilization following a referral letter, (2) characterize factors (barriers and supports) which influenced uptake of services, and (3) identify potential strategies for increasing utilization. This study evaluated the uptake of cancer genetic counseling among 603 screening mammography patients identified as having an increased risk for HBOC based on National Comprehensive Cancer Network (NCCN) guidelines. At risk individuals and their primary care providers were mailed a referral letter recommending genetic counseling. Three focus groups (N = 24) were conducted to identify responses to receiving a letter recommending genetic counseling, barriers to seeking genetic counseling, and facilitating factors to utilizing these services. Participant responses were qualitatively analyzed using thematic and cross case analysis. Within one year, 50/603 (8 %) of the identified at-risk women completed a genetic counseling appointment. Participant-perceived barriers which influenced their decision not to seek genetic counseling included lack of relevance and utility, limited knowledge about genetic counseling, concerns about the genetic counseling process, and concerns about cost and insurance coverage. Participant-perceived facilitating factors which would support a decision to seek genetic counseling included greater awareness and education about genetic counseling services when receiving a referral, and improved follow up and guidance from their provider. Findings from this study support the need for patient and primary care provider education, and improved provider-patient communication to increase uptake of genetic counseling services.  相似文献
