This study aimed to investigate contextual influences on condom use by South African university students. Twenty one-to-one, semi-structured interviews were conducted with male and female South African undergraduates. The data were thematically analysed. Results revealed that condom use was transient and often unrelated to disease prevention. Condom use was impeded by closer perceived intimacy, gender dynamics, and social stigma against proposing use of condoms in a presumably committed relationship. Public health policies regarding condom, pill and injection pricing / promotion, and religious toleration also hampered condom use, by encouraging a preference over hormonal contraception or proscribing contraceptive measures altogether. The results provide a basis for considering the impact of immediate and wider social contexts on condom use, as proposed by socio-ecological models of HIV risk behaviour.  相似文献

In this paper I critically examine an argument proposed by Graham Priest in support of the claim that the observable world is consistent. According to this argument we have good reason to think that the observable world is consistent, specifically we perceive it to be consistent. I critique this argument on two fronts. First, Priest appears to reason from the claim ‘we know what it is to have a contradictory perception’ to the claim ‘we know what it is to perceive a contradiction’. I argue that this inference fails to be valid. Secondly, I give reasons for thinking that if an observable state of affairs were to be contradictory, we would perceive it to be consistent. As such that the world we observe appears consistent does not constitute evidence that it is in fact consistent. That we see a consistent world is no reason to believe that the world is consistent. I conclude the paper with some reflections on the implications of this analysis for the plausibility of trivialism.  相似文献

The utility of emotional approach coping (EAC), or expressing and processing emotions, has been equivocal for men. Gender role conflict, or the negative cognitive, emotional and behavioural consequences associated with male gender role socialisation, likely shape coping responses and may negatively affect the efficacy of men's emotion-directed coping efforts and adjustment to cancer. Perceptions of receptiveness of one's interpersonal environment may be particularly important to the effectiveness of EAC. This study examined the relationships among EAC, gender role conflict, and distress in a group of 183 men with cancer. Structural equation modelling revealed that higher gender role conflict was associated with lower emotional expression, which in turn was associated with greater distress. Gender role conflict was not related to emotional processing. Higher gender role conflict also was associated directly with more distress. In subsequent analyses, social constraints and age were examined as possible moderators of EAC. Emotional expression was related to more psychological distress for those in highly constrained environments; and emotional processing was associated with more distress with younger age. Emotional expression may be particularly affected by social influences related to gender and social receptivity. More research is needed to better distinguish constructive and unconstructive emotional processing.  相似文献

Previous research indicates that bar workers report high levels of alcohol consumption, but the bar work experience itself has been little studied as a means to understand health threats associated with this job role. The subjective experience and meaning of bar work was explored in this study by interviewing current and ex-bar workers from a district in an Irish city that had a high density of bars and busy tourism industry. A total of 12 participants took part in focus groups (FGs) and seven in individual interviews. Four themes were identified in a thematic analysis. The central depiction of bar work was of an initial immersion in an intensive lifestyle characterised by heavy drinking, with subsequent distancing from the extremes of the lifestyle. The participants affiliated strongly with the bar work occupational identity, which included alcohol use in group scenarios for drinking during work, after work and on time off. The bar work lifestyle was most intense in the ‘superpub’ environment, characterised by permissive staff drinking norms and reported stress. Although an important identity, bar work was ultimately a transient role. The findings are considered in relation to research on occupation-specific stress and alcohol use, social identity and developmental needs in young adulthood.  相似文献

Brain donation is critical to understand the pathological causes of neurodegenerative diseases. Increasing levels of donation requires an understanding of those factors that both encourage and deter donation. At present, there are few studies of how people understand, feel and decide about brain donation for scientific research. This qualitative experiential study contributes to the growing literature on brain donation through its specific focus on how the donation process is experienced from the perspectives of family members and friends. Nineteen semi-structured interviews were analysed using a phenomenologically informed thematic analysis. Four themes were derived from the analysis, three of which are described in detail: Making the decision to donate; a personal perspective on the donation process; the significance of the brain; beliefs about brain donation. In particular, the thematic analysis highlights the variation of individual decision making and the emotions and reasons underpinning such decisions. Key conclusions include the importance of integrated practice amongst relevant healthcare professionals as well as the need for supportive and informed communication. Also, in light of the finding that the brain assumed no special significance for most participants, the value of the distinction between brain donation for research purposes and organ transplantation is questioned.  相似文献

In the current study, we tested the effects of core body temperature increases (e.g. heat stress) on affect, self-reported physical discomfort, and subsequent self-control in male smokers and nonsmokers using a novel passive heat stress paradigm, within a distress tolerance framework. Twenty-eight men (14 smokers), completed both heat stress and control sessions in randomized order. Results revealed that increases in core body temperature were associated with increased anxiety, irritability, and body discomfort as well as decreased happiness, with stronger effects for smokers. Smokers and nonsmokers both evidenced less self-control during the heat session and did not differ on this measure, nor on a measure of interoceptive sensitivity. The current study indicates that heat stress is a viable method for studying distress tolerance in men, and suggests the value in examining dynamic changes in self-control as a function of distress. Implications will be discussed for distress tolerance in general and smokers in specific.  相似文献

This study explores conceptualisations of same‐ versus different‐sex infidelity in the context of a heterosexual marriage using story completion. A convenience sample of 57 female and male participants completed one of four versions of a story stem featuring a husband who is either emotionally or sexually unfaithful with a woman or a man. A social constructionist thematic analysis found that same‐sex infidelity was conceptualised as the ‘worst case scenario’ and was underpinned by a heteronormative framing of repressed homosexuality. By contrast, heterosexual infidelity was understood in terms of relational deficits and the wife assuming responsibility for these. Overall, the analysis shows that in making sense of same‐sex and heterosexual infidelity, the participants drew on familiar discourses of sexuality and gender, suggesting that despite social psychological theorising related to sexual fluidity, essentialist ideas remain firmly in place. Methodologically, the study demonstrates the usefulness of a rarely used tool—the story completion task—for accessing socio‐cultural discourses and dominant meanings surrounding a particular topic.

ObjectivesWithin Great Britain, increasing numbers of elite sport performers are attending higher education institutions. The current study presents an exploration of the transitional experiences of these individuals at a specific British university. Wylleman and Lavallee's (2004) developmental model on transitions faced by athletes and Stambulova's (1997, 2003) athletic career transition model were used to provide the theoretical foundation of inquiry.Design and methodAn instrumental case study design was adopted to provide an in-depth analysis of student-athletes’ experiences at a university. The case university was selected based on its provision of elite sport support services. To acquire a holistic understanding, interviews were conducted with current and recently graduated student-athletes from the university, and focus groups were run with university staff (viz. administrators, coaches, and support staff). Qualitative data were analyzed using a thematic framework approach.ResultsElite student-athletes at the British university were found to experience simultaneous athletic, academic, psychological, and psychosocial transitions. To overcome the transitional demands, student-athletes were found to draw on a variety of internal (e.g., self-awareness) and external (e.g., academic flexibility) resources and to implement coping strategies (e.g., seeking social support). Potential barriers to successful transitions were also identified (e.g., parental overprotection).ConclusionsThese findings advance the limited existing literature on British university student-athletes’ transitional experiences and suggestions are provided for how other universities can enhance provision for their elite student-athletes.  相似文献
