Gender comparisons of injection drug use practices in shooting galleries

Previous research studies and anecdotal evidence portray shooting galleries as locales that place injection drug users at great risk for HIV infection, drug use and violence. Collectively, these studies highlight the need to intervene with injectors who frequent shooting galleries. However, few researchers have studied an often-forgotten risk group – women injecting drug users who frequent shooting galleries – and compared their risk behaviors to their male counterparts. To address this gap in the research literature and to evaluate the functionality of the shooting gallery as a setting for HIV prevention, we collected data on risk practices from 201 injectors (101 men and 100 women) who were recruited from eight shooting galleries in Miami, Florida. Results indicate that, compared with men, women injectors engaged in a similar variety and frequency of injection risk behaviors and had more shooting companions. While only minor gender differences were apparent, relatively few injectors – male or female – adhered to current recommendations for needle hygiene practices. Needle hygiene practices existed equally among injectors of both sexes, however very few adhered to current recommendations. Furthermore, contrary to common images of shooting galleries, use of other drugs was infrequently reported, episodes of violence or victimization were uncommon, and sexual contact almost never occurred. Operators of shooting galleries, both men and women, indicated their willingness to participate in HIV prevention efforts. Implications of these findings for HIV intervention indicate that (1) there is a great need to intervene with both men and women IDUs who frequent shooting galleries and that (2) shooting galleries can be an optimal setting for HIV prevention.     

HIV risk behavior and drug use among heterosexual male crack users by prostitution involvement

Crack and prostitution, or sex exchange, have been linked to the heterosexual spread of HIV (e.g. Inciardi 1993, 1995). Previous studies have found that among female crack users there are subgroups who do and do not become involved in prostitution (e.g. Logan, Farabee & Leukefeld 1998; Logan & Leukefeld 1998). However, there has been little focus in the literature on subgroups of male heterosexual crack users who are or are not involved in prostitution. The purpose of this study was to examine differences in male heterosexual crack users who reported no involvement in prostitution as clients (n = 4,208), males who reported involvement in prostitution as clients but not in the month preceding the interview (n = 2,774), and males who reported involvement in prostitution as clients the month preceding the interview (n = 2,283) from a multi-site sample of male crack users who participated in the National Institute of Drug Abuse (NIDA) AIDS Cooperative Agreement Project from 20 sites across the nation. Results of the logistic regression indicated that having an STD three or more times and using drugs during sex were associated with ever being involved in prostitution as clients, while using drugs during sex and having 5 or more sexual partners the month preceding the interview were significantly associated with being involved in prostitution as clients at the time of the interview. Implications for interventions are discussed.     

HIV testing,perceptions of AIDS risk,and condom use motivation among US women

As STD infections including HIV increase in the United States, it has become increasingly important to policy makers to ascertain the extent to which knowledge and perceptions of AIDS risk affect an individual's probability of altering their sexual or contraceptive behavior to avoid infection. This paper examines the extent to which women's perceptions of their own and their partners' risk of HIV infection affects the probability of using a condom for protection against sexually transmitted diseases. This paper also examines the extent to which HIV testing may affect motivation for condom use. Crosstabulations reveal that prophylactic condom use is more prevalent among women who have been tested for HIV and increase as perceptions of their chance (and their partner's chance) of being positive increases. The multivariate results from this study indicate that having an HIV test significantly predicts the likelihood of using a condom for STD prevention for US women. Furthermore, women who perceive themselves to be at least somewhat likely to be HIV positive have a higher probability of using a condom to prevent sexually transmitted disease, and women who perceive their partners to be HIV positive are twice as likely as other women to use a condom for STD prevention. However, women who consider themselves likely to be HIV positive are no more likely to use a condom than those who consider themselves not at risk.     

The prevalence and incidence of HIV among injection drug users: A five year panel study

Six hundred and one injection drug users (IDUs) who attended drug treatment programs in Miami, Florida, were enrolled in a panel study to determine the prevalence and incidence of human immunodeficiency virus (HIV) and associated risk factors. A structured questionnaire which elicited injection and sexual behaviors was administered and blood was obtained by venipduncture. All participants were reassessed at six month intervals for 5 years. The baseline prevalence of HIV was 16.3%. African–Americans had a prevalence of HIV (37.1%) that was significantly higher than that of non-Hispanic whites (7.6%); the prevalence of HIV among Hispanics was 27.2%. Persons who were more than thirty years of age were more likely to test HIV positive (17.8%) than were younger participants (9.7%). The annual incidence per 1000 person-years of exposure for the 503 initially seronegative participants was consistently low for each year of the study. The 5 year incidence was 4.1 per 1000 person years; 7.5 for men and 1.7 for women, 7.5 for African–Americans and 3.8 for non-Hispanic whites. No Hispanic participants seroconverted. Multivariate logistic techniques were used to identify the independent risk factors for HIV prevalence. Earlier injection, ethnicity, and income were independently associated with HIV serostatus. A history of a sexually transmitted disease was marginally associated with HIV prevalence. Low incidence probably is a function of the reduction of risk behavior that occurred over the course of the study and the stage of the epidemic.     

吸毒人群对艾滋病防治的接纳现状与影响因素

近年来我国已经把吸毒人群作为艾滋病防治的重要干预对象之一,然而现状不容乐观,吸毒人群传播艾滋病的风险远未得到有效控制。探讨影响吸毒人群对艾滋病防治措施的认同和接纳的因素,以便为完善艾滋病防治措施提供新的思路。研究表明,吸毒人群的认知水平、社会支持、政策保障、人生态度等因素对其接纳艾滋病防治措施有影响。只有将吸毒人群视为弱势群体予以增权和关爱,以"合作"的社会政策导向和"平等"的社会工作价值介入,从其需求入手开展务实多样的防治措施,才有可能真正改变吸毒人群的观念与行为,从而获得艾滋病防治的良效。     

新型农村合作医疗的参合补助——悖论及路径优化

新农合的财政补助水平与农民需求存在较大缺口,客观上需要政府提高补助水平。但由于农民有限理性的存在,在个人缴费在先且与财政补助同比增长的制度安排下,形成了农民既需要参合补助,又不愿因增加个人缴费以获得补助的悖论,且此情况会因制度供给缺陷而激化。因此,需要对新农合的参合补助路径进行优化。设计灵活的参合缴费模式,调整农民缴费与政府补助的增长幅度,提高农民医疗补偿的比例都是可行的选择。     

Technological change and sociocultural models in China: A case study of train commuters in Beijing

ABSTRACT

China’s mobility turn has created the world’s largest public rail system, contributing extensively to citizens’ economic, social, and spatial mobility. Concurrently, this technological transformation has introduced many opportunities for individuation, which could potentially challenge the social, collectivistic, and Confucian foundations of China’s sociocultural and political ideology. While the notion that ‘mobility produces culture’ is readily accepted, research on train mobility in China is rare. In this study, we use Albert Bandura’s Model of Triadic Reciprocal Causation to conceptualize mobility as agency. We employ Hermeneutic Content Analysis, a mixed methods framework, to study how this rapidly evolving mobility environment connects to the lives of 31 regular train users living in Beijing. Studying agency in China enables us to systematize the sociocultural models within which mobility practices are embedded and how they manifest. We find that our interviewees embed agentive practices in a cultural model that is intertwined with collectivistic aspirations of the country. Technological developments are thus integrated into existing sociocultural models and political expectations, contradicting existing debates on the fracturing impact of disruptive technologies.

Population Dynamics and Tropical Deforestation: State of the Debate and Conceptual Challenges

What is the role of population in driving deforestation? This question was put forth as a discussion topic in the cyberseminar hosted by Population Environment Research Network (PERN) in Spring, 2003. Contributors from diverse backgrounds weighed in on the discussion, citing key factors in the population-deforestation nexus and suggesting further courses of action and research. Participants explored themes of their own choosing, with many coming to the forefront. Scale, time, and place-based effects were cited as areas in need of particular attention. Consumption patterns as the mechanism for spurring deforestation were discussed, drawing attention to the differential patterns associated with urban vs. rural demands on forest resources and land. The applicability of the IPAT formula and the influence of its component parts, affluence and technology, when operating in tandem with population, was debated. The relation of demographic factors to these pathways was critically examined. Institutional and governmental influence, such as infrastructure and policies affecting access and incentives, the valuation of resources, and institutional failures such as mismanagement and corruption emerged as a crucial set of factors. This article synthesizes the critical debates in the population-deforestation literature, makes suggestions for future paths of research, and discussed possible policy and direct action initiatives.     

Women's empowerment as a public problem: A case study of the 1994 International Conference on Population and Development

Using the 1994 International Conference on Population and Development (ICPD) as a case study, I examine how women's empowerment amassed public attention. I investigate feminist preparations for the conference and suggest that by playing an active role in preparatory meetings and the conference, women gained recognition from governments throughout the world and from the United Nations, and helped frame issues in a way that motivated the press to highlight women's empowerment. I argue empowering women became a catch phrase for media coverage and that abortion surfaced as a symbol of this empowerment. UN publications and reports of proceedings prior to, and during the 1994 ICPD, and articles from The New York Times illustrate use of this media package. The paper raises questions about types of policies governments will use to improve the position of women and the political power women will have in decisions.
