The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction.  相似文献

Abstract

This paper investigates whether eight specific life-events were related to self-reported chronic (persistent trouble over the last 12 months) and acute (trouble in the last 14 days) oral symptoms in a sample of 3861 civil servants aged 35-44 years. The results of a logistic regression analysis taking age, social class and gender into account showed that a range of life-events—marital or family problems other than divorce, death of a relative, personal serious illness, serious illness of a close relative, major financial difficulty and mugging and robbery—were significantly associated with either acute or chronic oral symptoms. Further analysis showed that marital or family problems other than divorce was found to be the most important life event studied. The results support the argument that marital dissatisfaction leads to poorer physical and psychological health.  相似文献

Abstract

This study developed and validated an Asthma Multidimensional Health Locus of Control (AMHLC) scale using 186 asthmatics aged 13 to 55 years recruited from 46 pharmacies in the Hunter Valley, Australia. The construct validity and internal consistency of the scale were demonstrated using principal components factor analysis and Cronbach's alpha respectively. Although correlations were modest, findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those with higher “Chance” scores. Powerful Others orientation was also associated with expectations and valuation of services doctors' provide. Knowledge of asthma was not related in the expected direction with the new scale, nor were clinical indices of asthma severity. Younger asthmatics had higher Chance scores while older asthmatics tended toward higher Powerful Others orientation. Overall, the AMHLC instrument achieved suitable measurement properties to allow further investigation of health care behavior in people with asthma.  相似文献

Very little is known about the reasoning underlying beliefs in complementary and alternative medicine (CAM). This study examined whether CAM beliefs can be better explained with intuitive reasoning, paranormal beliefs and ontological confusions of physical, biological and mental phenomena than with 12 variables that have typically been used to explore the popularity of CAM, namely gender, education, income, age, health, desire to control treatment, satisfaction with conventional medicine and world view (unconventional, feministic, environmentalist, exotical and natural). A representative sample of Finnish people (N = 1092) participated in the study. The results showed that intuitive thinking, paranormal beliefs and ontological confusions predicted 34% of the variation in CAM beliefs, whereas the 12 other variables increased the prediction only by 4%. The results help to explain individual, cultural and situational differences in the popularity of CAM and to differentiate between CAM statements that can be scientifically examined from those that cannot.  相似文献

According to some philosophers who accept a propositional conception of evidence, someone's evidence includes a proposition only if it is true. I argue against this thesis by appealing to the possibility of knowledge from falsehood.  相似文献

The aim of this qualitative research was to explore and describe perceptions of the potential role of traditional healers in education support services. Participants were 42 teachers (males = 13, females = 29) from a school district in the Eastern Cape province of South Africa. Interview and questionnaire data were collected and analysed, using a phenomenological method. Two main themes emerged from the analysis for the role of THs as education support providers: as 1) representatives of African culture and 2) contributors towards harmonising diversity in schools. The recommendations made were in line with the findings.  相似文献

The social media uproar in Fall 2017 over a nursing textbook chart that presented generalised characterisations of minority groups generated an assumption that medical training needs more Religious Studies expertise. Analysing the sources that the chart cited, we trace the authors’ assertions to studies of varying quality and identify several specific processes involved in simplifying knowledge for dissemination, as the authors disregarded the limits of each specific study and ignored counter-evidence or otherwise evaded critical scrutiny. Comparing this example to examples from world religions discourse illustrates both differences and similarities in the process of constructing simplified presentations. While both presumably developed out of good intentions, they generate significant problems in their effort to shape material to support larger arguments. Thus, scholars across disciplines should critique and complicate their own processes for generating simplified knowledge.  相似文献

While it is generally agreed that in the postmodern world all tradition is invented, in many post-colonial contexts the emerging identities are spelled out in the idiom of ‘traditional heritage’. This article considers the social field of ‘shamanism’ as it has been shaped in the post-Soviet years in Tuva, an autonomous republic within the Russian Federation in Southern Siberia, and analyses Tuvan shamanism as a product of local historical and social forces, and global processes. Based on both the ethnography of the organisational structure of contemporary Tuvan shamanism, and portraits of different categories of practitioners, the article analyses continuity and change in various aspects of what is locally seen as ‘traditional knowledge’, and discusses different skills, orientations, and divisions of labour among the practitioners. Shamanism in post-Soviet Siberia is seen as a postmodern religious movement enmeshed in global structures and processes, and it is only in this context that a local tradition can become alive and meaningful again.  相似文献
