Discordant couples are unique because partners do not share the same serostatus. Yet research overlooks how they became discordant, mistakenly assuming that they have always been that way and, by extension, that being discordant impacts the relationship in a similar manner. This study examines HIV infection history and its impact on relationship dynamics using qualitative data from 35 discordant gay male couples. Most couples were discordant when they met (69%); however, many were not (31%). Those couples that met discordant felt being discordant had a lesser impact on their sexual and relational satisfaction, while those that did not meet discordant felt it had a greater impact, reporting sexual frustration and anxiety over seroconverting. This suggests that relationship dynamics may differ for discordant couples depending on HIV infection history. HIV prevention and counseling services for discordant couples can be better tailored and more effective when differences in HIV infection history are recognized.  相似文献

In the general framework of quantitative methods for natural‐technological (NaTech) risk analysis, a specific methodology was developed for assessing risks caused by hazardous substances released due to earthquakes. The contribution of accidental scenarios initiated by seismic events to the overall industrial risk was assessed in three case studies derived from the actual plant layout of existing oil refineries. Several specific vulnerability models for different equipment classes were compared and assessed. The effect of differing structural resistances for process equipment on the final risk results was also investigated. The main factors influencing the final risk values resulted from the models for equipment vulnerability and the assumptions for the reference damage states of the process equipment. The analysis of case studies showed that in seismic zones the additional risk deriving from damage caused by earthquakes may be up to more than one order of magnitude higher than that associated to internal failure causes. Critical equipment was determined to be mainly pressurized tanks, even though atmospheric tanks were more vulnerable to containment loss. Failure of minor process equipment having a limited hold‐up of hazardous substances (such as pumps) was shown to have limited influence on the final values of the risk increase caused by earthquakes.  相似文献

Eighty-three low-income Mexican-heritage children (44 girls) and their mothers participated in this research. Children were observed with alternative caregivers at 14, 24, and 36 months of age using the Attachment Q-Set. Most children received regular care from infancy through preschool from relatives and childcare providers. Children had high attachment security scores with both mothers and caregivers. Child–mother and child-alternative caregiver attachment security scores were independent of each other. Children whose mothers did not participate in family clusters were lowest in child–mother attachment security at 14 months. More emotionally sensitive mothers and responsive alternative caregivers were associated with more secure child–adult attachments. Mothers who had more contact with relatives still in Mexico were more likely to have somewhat more positive relations between intrusive interaction and positive attachment relationships than mothers who had less contact.  相似文献

The district of Kodagu, also called Coorg, in the Western Ghats of India produces 2% of the world's coffee, the expansion and intensification of which have reduced the forest cover by more than 30% in 20 years. Innovative actions are therefore urgently required to link economic development and biodiversity conservation, and stakeholders are exploring three strategies to add value to coffee from Coorg and prevent further biodiversity erosion: registration of trademarks; geographical indications; and environmental certification, via eco‐labels. This article analyses their respective strengths and weaknesses and discusses the synergies between them.  相似文献

This article is focused on the sexual attitudes and behaviour, and knowledge of AIDS of a group of students of Moscow State University. Reference will also be made to surveys dating back to the beginning of the century, when Russia and then the Soviet Republic were at the forefront in this field of research, in that they help throw light on past trends and present tendencies.The first sexual intercourse (FSI) is relatively early for male students (median age = 17.7) and relatively late for females (18.9). Mean number of partners per year is not low, and it is the same for both males and females (almost 1.7). This is not the case in Western countries. Moreover, contraception at FSI is at a low level. Sexual attitudes are permissive -- particularly concerning infidelity -- and there is a general concern regarding the spread of AIDS. However, specific knowledge about AIDS transmission is lacking.  相似文献

Passion and sexual satisfaction typically diminish in longer-term relationships, but this decline is not inevitable. We identified the attitudes and behaviors that most strongly differentiated sexually satisfied from dissatisfied men and women who had been together for at least three years (= 38,747). Data were collected in 2006 from cohabiting and married men (M) and women (W) via an online survey on a major national U.S. news Web site. The vast majority of these participants reported being satisfied with their sex lives during their first six months together (83% W; 83% M). Satisfaction with their current sex lives was more variable, with approximately half of participants reporting overall satisfaction (55% W; 43% M) and the rest feeling neutral (18% W; 16% M) or dissatisfied (27% W; 41% M). More than one in three respondents (38% W; 32% M) claimed their sex lives were as passionate now as in the beginning. Sexual satisfaction and maintenance of passion were higher among people who had sex most frequently, received more oral sex, had more consistent orgasms, and incorporated more variety of sexual acts, mood setting, and sexual communication. We discuss implications of these findings for research and for helping people revitalize their sex lives.  相似文献

The aging male is fast becoming a global concern. The problem is predicted to become a major health issue that should be addressed immediately in order to prevent disability, morbidity, and, more importantly, mortality. As part of its commitment to increase awareness and create interest in the care of Filipino aging males, The Philippine Society for the Study of the Aging Male Foundation, Inc. (PhiSSAM), a multi-specialty society established in 2000, embarked on a survey among Filipino physicians to determine their knowledge, attitudes, and practices regarding male aging. Results showed that the majority of doctors (about 87%) thought that men may experience andropause. Most would diagnose patients based on symptoms alone, while only 20–30% used testosterone levels to make a diagnosis of andropause. Decreased libido and less strong erections were the symptoms very closely associated with low testosterone. Of those doctors responding, 89% agreed that andropause can affect the quality of a man's life as much as menopause can affect a female; only 38% had already prescribed/instituted treatment for andropause. Of the 62% non-prescribers, 58% said they were either very likely or fairly likely to institute treatment in the future if there were more clinical trials, more medical information, and more information on drugs. Major concerns on testosterone replacement therapy included prostate cancer, benign prostatic hypertrophy, and heart disease. The findings in this pilot survey indicate a need among the doctors in the Philippines for education about andropause and the available treatments.  相似文献

This article reports the findings of a study of perceived barriers to volunteering to formal organizations by nonvolunteers. We examine the types of barriers, their frequencies, and their relationships with individual‐level sociodemographic characteristics of nonvolunteers. Data from a 2001–2002 national survey conducted by the U.S. Bureau of Labor Statistics are analyzed using multiple regression techniques. Contrary to general expectations, only three barriers—lack of time, lack of interest, and ill health—are fairly common. Furthermore, as expected, different social class groups identify different types of barriers. The article concludes with a discussion of the theoretical implications of the findings (for example, how indicators of social and cultural capital affect access to volunteer opportunities) and practical implications concerning recruitment of volunteers.  相似文献

In this brief article, we present the Self-Weighting Model (SWM), a new weighting model for statistical analysis. SWM allows within/between-set comparisons, producing estimates with a discriminatory power not found through current weighting strategies. The model is applicable to a wide range of statistical problems for which conditional weighted means are required.  相似文献

This article describes an effort to further infuse social justice education into doctoral programs in social welfare. It articulates the rationale and tactical approaches for aligning mission statements with the operational realities of university contexts. Within 1 school of social work, doctoral students with diverse orientations to social justice came together to articulate a vision for social justice education that expanded the educational contract between students and the institution by enhancing their respective opportunities and responsibilities in the areas of scholarship, teaching, and service. This article shares 30 learning objectives emergent from an incremental change process for enhancing social justice education at the doctoral level and reflects on the strengths and limitations of this approach to advancing social justice priorities.  相似文献
