Time‐Dependent Functions for Avoidance Behaviors Made in Response to the Circulation of HIV and AIDS

Interventions aimed at preventing HIV transmission include avoidance behaviors like condom use and reduced partner acquisition. In turn., engagement in such activities might also entail changed patterns of travel to evade contact with infected individuals. One method of estimating the effects of these actions on the observed distribution of HIV/AIDS involves the specification of space‐time models that imitate the epidemic process. This paper presents an application of this procedure where prevention is construed as a continuous population response to the evolving distribution of HIV and AIDS. This task entails the construction of models with time‐dependent parameters adapted to predicted prevalence or incidence measures to represent the effects of specific avoidance behaviors. In this respect, a multiregion model is described that serves as a baseline for analyzing the impact of preventative actions on the HIV/AIDS epidemic in Western Europe. A series of adaptation functions are derived within this system for imitating both changed rates of partner acquisition and altered travel behaviors. The results elicit modifications to the behavior of the baseline epidemic that are generated by each of these functions. Then, the conditions supporting space‐time variations in rates of survival between core countries (relatively low) and those in the periphery (relatively high) are investigated. The discussion considers the implications of these results for health policies that promote avoidance behaviors.     

Wealth alone does not buy health: Political capacity,democracy, and the spread of AIDS

Although there have been have numerous studies on AIDS documenting its mortality, its epidemiological features, and its relationship to poverty and development, few studies have systematically analyzed how political factors and policies may help curtail the spread of AIDS. In this paper I consider how a variety of domestic factors influence HIV infection rates across countries. I argue that states with higher state capacity are better able to reduce the spread of the HIV/AIDS epidemic. Moreover, I argue that while strong autocracies can implement efficient policies with fewer constraints, democracies tend to be more responsive to the needs of the population and can be more efficient in curtailing the spread of HIV/AIDS. I empirically evaluate the hypotheses using a cross-sectional time-series sample of 117 countries. The empirical results indicate that greater state capacity indeed appears to help curtail HIV/AIDS infection rates.     

Reconstructing the Space-Time Structure of the HIV/AIDS Epidemic for the Countries of Western Europe

This paper applies a compartmental epidemic modelling system to the estimation of HIV infection transfers between the nations of Western Europe for the period 1973–98. This multiregional model imitates the formation of disease contacts by both local and international travel, where the latter is assumed to have the lower sensitivity to the effects of spatial separation. This system is calibrated in two stages: first, disease parameter sets are found to best fit the timing of recorded AIDS incidence in each nation; and second, these sets are entered into a multiregion setting to identify the travel parameters that support the lags between these series. The outputs include estimates for the first year of HIV incidence in each country and the subsequent pathways of infection transfer that connect these dates. The results indicate the contrasting roles of the southern and northern countries within the continental epidemic and point to national variations in the recent delaying effects on AIDS incidence of drug combination therapies.     

Great Ancestral Women: Sexuality,Gendered Mobility,and HIV among the Bamu and Gogodala of Papua New Guinea

Faced with a potentially devastating epidemic of HIV/AIDS in Papua New Guinea (PNG), sexuality and mobility have become a focus of national research and prevention programs. In Gogodala and Bamu communities in the Western Province, gendered mobility and sexuality intersect with ancestral narratives that form part of a wider series of Hero Tales found in the southern regions of PNG and Irian Jaya. In this paper we highlight the way these stories detail the travels and activities of female ancestors – known as Sagalu among the Bamui and Sawiya among the Gogodala. We outline the way such ancestral figures are now linked to understandings of contemporary STIs such HIV/AIDS as well as gendered mobility and sexuality more generally. Among the Bamu such links are sometimes directly asserted, with Sagalu represented as the origin if not cause of a uniquely defined variant of HIV/AIDS. Among the Gogodala, however, HIV/AIDS is predominantly understood as something external to the Gogodala and unrelated to ancestors like Sawiya. To explain this difference we note that, historically, Gogodala women have been less mobile and less transactable than their Bamu counterparts who have continued to enact unique understandings of the intersection of heterosexual marriage, gendered mobility, and illness. We argue that the mobility and sexuality of gendered ancestors is salient to understanding these contemporary enactments and their potential implications in light of the HIV epidemic in PNG.     

Privileging prevention,gendering responsibility: an analysis of the Ghanaian campaign against HIV/AIDS

This article focuses on the discourses around HIV/AIDS in the national Ghanaian ‘Stop AIDS Love Life!’ public health campaign, within non-governmental HIV/AIDS publications, and the Ghanaian national print media. I have used critical discourse analysis to interpret and deconstruct a range of these social texts collected between June and September of 2001 and 2003 in and around Greater Accra, Ghana. I argue, firstly, that these discourses are shaped by an international politics of funding for HIV/AIDS that privileges prevention through behaviour change over treatment action under the premise that prevention is a more cost-effective option for the Global South. I critique this stance, highlighting the emerging possibilities for integrated prevention–treatment efforts in resource-poor settings such as Ghana. Secondly, I argue that the discourses around HIV/AIDS presented in prevention campaign materials powerfully construct normative and gendered subjectivities with assigned roles and responsibilities. The fight against HIV/AIDS is constructed as a national project in which an idealized, and often very young, female citizen is positioned as educator, volunteer, carer and protector of herself and society. This discursive coding of responsibility places the many burdens of HIV upon some of the most vulnerable in society, ignoring the structural constraints of gender, generational and economic inequality. I conclude my paper by arguing that efforts to reduce transmission rates, stigma, and the burden of care for those living with HIV/AIDS in Ghana must integrate both preventative efforts and treatment action. Where prevention campaigns are utilized I suggest that these must recognize the limitations of behaviour change initiatives that primarily target women and acknowledge the gendered constraints faced by those very subjects identified as responsible for the protection and education of the nation.     

Securitising HIV/AIDS in the Xinjiang Uyghur Autonomous Region

For the People's Republic of China, the localised HIV/AIDS epidemics in the Xinjiang Uyghur Autonomous Region are emerging as threats to those persons affected by the disease, but also to the stability of Xinjiang. This article examines the HIV/AIDS epidemic in Xinjiang and considers the impacts it may have on human and political security. The authors argue that due to its remote location and the religious, cultural and ethnic diversity of its population, and current political situation, Xinjiang poses difficult obstacles to effective programs in tackling HIV/AIDS, and the pandemic has disproportionately affected the minority nationalities in the region compared to their Han counterparts. If the HIV/AIDS pandemic among minority nationalities in Xinjiang continues to grow, it has the potential to further weaken social cohesion there, as well as Uyghur human security. Therefore, a HIV/AIDS pandemic in Xinjiang could tip the balance in terms of ethnic and regional stability.     

AIDS Activism in Pakistan: Diminishing Funds,Evasive State

This article draws on a year of ethnographic fieldwork in the HIV/AIDS sector of Pakistan at the moment of rolling back a World Bank‐financed programme. Classified by UN agencies as at ‘high risk’ of a generalized HIV epidemic, Pakistan has an epidemiology driven by injecting drug use, and a Penal Code and Islamist legislation which criminalize non‐therapeutic drug use and extra‐marital sex. In recent years, a sharp increase in the numbers of registered HIV‐positive people has necessitated a shift from HIV prevention among ‘high risk groups’ to the provision of care to those living with HIV/AIDS. The rolling back of external funding, which was further compounded by the effects of devolution on the Ministry of Health, created challenges for AIDS activism in Pakistan, as reflected in the everyday lives — and deaths — of the patient‐activists and their community‐based organizations. This article recounts the story of one such aspiring AIDS activist caught in multiple dilemmas emanating from these macro‐processes. This story throws light on the limitations of the complex agency of actors in development, and shows how the shifting loci of power from the state to non‐state entities in the global neoliberal order impacts the provision of vital services like HIV prevention and AIDS control.     

After the Exception: HIV/AIDS Beyond Salvation and Scarcity

Abstract: Access to treatment for HIV/AIDS became a flashpoint for global justice struggles in the late 1990s. An expanding international response, premised to a significant extent on the idea of HIV/AIDS as an exceptional global problem, has since delivered treatment, care and prevention to growing numbers of people. HIV/AIDS exceptionalism, however, has increasingly been questioned, many aspects of the response have been critiqued and donor funding has started to decline. I argue that, having been framed as an exceptional humanitarian emergency, the question of HIV/AIDS as a global problem is increasingly located within a discourse of scarcity. Tracking the growing entanglement of global HIV/AIDS relief with neoliberal governmentality and the emergence of something I term therapeutic neoliberalism, I argue that the shift from a rationality of salvation to one of administration poses new challenges for global health activism. Questioning the discourse of scarcity remains essential to an alternative global health agenda.     

AIDS. Grim news for Asia

While Asia was the last region to be exposed to the global spread of HIV and AIDS, the incidence of HIV infection there is increasing fastest. The Asian Development Bank predicts mortality from AIDS will cause some town and village populations to begin declining by the year 2000. With an estimated 1 million people infected in India, and 400,000 in Thailand, these 2 countries are particularly exposed to the risk of epidemic HIV spread. In 5 years, more people may be affected by AIDS in India than anywhere else in the world. Concern over a growing presence of HIV is also merited for the Philippines, Indonesia, China, and the drug trade's Golden Triangle. The Second International Conference on AIDS in Asia and the Pacific in November 1992 stressed that AIDS no longer affects only homosexual and IV drug using populations. 50% of new infections worldwide in the first half of 1992 were among women, 65% of Thailand's AIDS cases are among heterosexuals, and 3-5% of Thailand's long-haul truck drivers have tested positive for HIV infection. HIV and AIDS robs economies and societies of their best workers. The immediate costs of caring for AIDS patients will pale next to the far greater losses to be realized in private sector economic productivity. Asia's more developed economies will probably be able to survive the epidemic, but small, poor countries like Laos will wilt. Prompt action must be taken to overcome public and religious ignorance and objections to promoting and using condoms throughout the region. For the first time, Beijing has organized an AIDS awareness conference for male homosexuals. Further, Singapore has implemented compulsory testing for lower-income foreign workers. Pakistan has even solicited educational assistance and support from Islamic religious leaders; similar action is being considered in Bangladesh.     

Medical Research Council Programme on AIDS in Uganda – the first 10 years

Abstract

The Medical Research Council (MRC) Programme on AIDS in Uganda is based at the Uganda Virus Research Institute of the Ugandan Ministry of Health in Entebbe on the shores of Lake Victoria. The programme was established following a request in 1988 from the Ugandan Government to the UK Government for assistance with AIDS, which had recently been discovered to be a large and growing health problem in the country. At that time Uganda had the worst published rates of HIV infection in the world. Over the past 10 years, Uganda has to some extent controlled its AIDS problem while other countries have been overtaken by even worse epidemics. From the outset of the epidemic Ugandan political leaders have discussed the dangers that HIV infection presented to the country and looked for support from community and opinion leaders, including religious groups. They have used available human resources in a relevant manner to trigger important social changes. Sex education is becoming integrated into the school curriculum, programmes have been established to improve the treatment of sexually transmitted diseases throughout the country, and the use of condoms has been actively and widely promoted through free distribution and social marketing. In Uganda today, experts estimate that 10–25% of the urban population and 4–10% of the rural population are infected with HIV.     

Alternative Population Dynamics in Selected HIV/AIDS Modeling Systems: Some Cross-National Comparisons

This paper examines how demographic representations for the different risk populations influence the epidemic outputs of a simple process-based HIV/AIDS model. Alternative demographic specifications are presented in conjunction with transmission rules for both community and regional settings. Then, the existence, or nonexistence, of equilibrium solutions to these various models is determined to evaluate whether the forecast AIDS series will persist indefinitely or eventually terminate. Last, simulations for countries with distinctive birth and death rates are used to summarize the effect of this variation on the timing and size of the epidemic. All the results assume an epidemic that is unaffected by the practice of safer sex.     

Spatial Diffusion of the HIV/AIDS Epidemic: Modeling Implications and Case Study of AIDS Incidence in Ohio

This paper extends a compartmental epidemiological model for HIV transmission and AIDS incidence to include hierarchical and expansion spatial diffusion. An implication of the resultant model is that hierarchical diffusion causes the large infection growth rates of densely populated areas at the top of the central places hierarchy to “chain” down and dominate small local growth rates during the exponential-growth phase of the epidemic. Also, hierarchical diffusion causes a high transient growth rate in the first few years of a local epidemic. The spatial compartmental model fits observed AIDS incidence spatial diffusion patterns in Ohio reasonably well.     

‘Let's talk about sex,baby…’: Conversing with Zimbabwean children about HIV/AIDS1

The lack of HIV/AIDS research with children under 15 in Zimbabwe indicates that most researchers believe children are too young to ‘talk about sex’. However, some are already sexually active, the rest soon will be and children constitute 45% of Zimbabwe's population. This mixed methods study surveyed 118 children and interviewed 36 about their understanding of sex and HIV/AIDS. The study revealed that the children had a range of knowledge levels about HIV/AIDS and sexual issues. It established that children can and want to discuss these sensitive issues, and that their attitudes towards safer sex are often more advanced than those of adults.     

The Response to HIV/AIDS and the Construction of National Legitimacy: Lessons from Uganda

Uganda faces continual challenges as a low‐income nation reliant on international donors and non‐state actors. It was also one of the first countries to face a population‐wide HIV epidemic, a disease that can strain state capacity to its limits. One would expect that such a combination would weaken the governance structures in a developing country; yet, if anything, the Ugandan state has emerged from its HIV crisis with its legitimacy bolstered. This article reviews the Ugandan response to HIV/AIDS, analysing the ways in which the epidemic has provided a new arena for the Ugandan state to engage with international actors.     

The Ryan White Act in Dallas

Virtually every locality affected by the AIDS epidemic has had to confront changes in the demographics of the disease, shifts in federal priorities, and medical advances in AIDS treatment. Creating a consistent federal policy has proven difficult because the epidemic manifests itself differently in virtually every locality it invades. As a result, some local caseloads increasingly are dominated by intravenous drug users and others by gay men. In recognition of this reality, the primary federal program to fund AIDS services relies on local decisionmakers to make allocation decisions for serving the needs of their caseload. Under the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act of 1990, local Health Services Planning Councils were assigned the task of creating an effective continuum of care for persons with HIV I AIDS and were empowered with the task of allocating federal funds to accomplish that objective. In some cases creating and fostering an effective continuum of care proved to be an essentially noncontroversial managerial task, while in other localities political turmoil and rampant self-interest served as barriers to program effectiveness. This article explores the relationship between local political culture and the development of AIDS programs in Dallas County, Texas. Specifically, we compare the provision of AIDS services in Dallas before passage of the Ryan White Act in 1990, how these services were affected by the Ryan White program, and the experiences since the reauthorization of the Ryan White Act in 1996.     

‘Turning Sex into a Game’: Gogodala Men's Response to the AIDS Epidemic and Condom Promotion in Rural Papua New Guinea

ABSTRACT Rugby league is the national sport of Papua New Guinea and the game's huge popularity and international profile has been used in recent condom promotion campaigns in the nation's fight against the HIV/AIDS epidemic. In this paper, I argue that the promotion of condom use through rugby league requires a national campaign strategy that includes understandings of condom use and masculinity at the rural level. I demonstrate this through a study of Gogodala men's understandings of the epidemic and condom use in Western Province. The Gogodala are a Christian‐based society and many blame the national condom promotion strategy for an increase in promiscuity and for ‘turning sex into a game’. Condom availability in this rural area continues to be restricted to a family planning program that promotes Christian values and excludes unmarried men. I explore the male condom dilemma where young men are more concerned with avoiding accusations that their sexual behaviour puts them at risk of contracting HIV despite acknowledging the preventative value of using condoms. In this context young men disassociate themselves from the disease and condom use through a process of calculated risk or risk minimisation.     

The Impact of AIDS on Rural Households in Africa: A Shock Like Any Other?

In areas where HIV prevalence is high, household production can be significantly affected and the integrity of households compromised. Yet policy responses to the impact of HIV/AIDS have been muted in comparison to outcomes of other shocks, such as drought or complex political emergencies. This article looks at the reasons for the apparent under–reaction to AIDS, using data from Zambia, and examines recent calls to mitigate the effects of AIDS at household level. Critical consideration is directed at proposals relating to community safety nets, micro–finance and the mainstreaming of AIDS within larger poverty alleviation programmes. It is argued that effective initiatives must attend to the specific features of AIDS, incorporating both an assault on those inequalities which drive the epidemic and sensitivity to the staging of AIDS both across and within households. A multi–pronged approach is advocated which is addressed not just at mitigation or prevention, but also at emergency relief, rehabilitation and development.     

An international public health crisis: can global institutions respond effectively to HIV/AIDS?

The United Nations Millennium Project (2005 UN Millennium Project , 2005 . Combating AIDS in the developing world ( London : Taskforce on HIV/AIDS, Malaria, TB, and Access to Essential Medicines: Working Group on HIV/AIDS, Earthscan ). [Google Scholar]) describes the HIV/AIDS epidemic as a ‘global catastrophe, threatening social and economic stability in the most affected areas, while spreading relentlessly into new regions’. Multilateral institutions under the leadership of the Joint United Nations Program on HIV/AIDS and World Health Organization have been charged with coordinating the worldwide response. Yet with attention and funding diverted between bilateral, regional and multilateral aid providers, and little discernible success in containing the global epidemic to date, it remains an open question whether traditional global institutions are able to effectively combat HIV/AIDS. It is argued that bilateral relationships are still heavily relied upon at present as traditional multilateral arrangements struggle for resources and political attention. The critical questions discussed here are whether global institutions should, can and will respond effectively to the HIV/AIDS crisis. This analysis finds that the most readily organised and deployed global response will likely involve an alliance of public and private agencies that can escape some of the domestic, political and organisational constraints inherent in existing HIV/AIDS funding arrangements. Ultimately, newer hybrid arrangements that have emerged recently, like the Global Fund to Fight AIDS, Tuberculosis and Malaria, may offer a more enduring global regime to control the HIV/AIDS epidemic. The corollary is that UN agencies alone in their traditional form, hampered by multilateral practicalities, will be less effective.     

Ryan White CARE Act Title I Funding Priorities and Unmet Service Needs in Baltimore, Maryland

The analysis presented in this paper explores the similarities and differences between the services selected as priorities for funding by the Baltimore Ryan White CARE Act Title I Planning Council during the first 2 years of the program in this metropolitan area, and services perceived by HIV/AIDS service providers and people living with HIV/AIDS to be unmet needs. The data used for these analyses were collected as part of a study to assess the implementation and impact of the CARE Act legislation in the Baltimore eligible metropolitan area( EMS ). This project includes three interrelated components: (a) a case study of the legislatively mandated Planning Council, (b) a survey of providers representing HIV/AIDS service organizations, and (c) a qualitative field study of the perceptions of people living with HIV/AIDS about the service delivery system. Taken together, the data from these three sources describe the similarities and differences among these three groups involved in HIV/AIDS care in Baltimore, in terms of their perceptions of services needed by people living with HIV / AIDS. The conclusions drawn from this study can be used to strengthen needs assessments in Title I-EMAs throughout the United States.     

Impact of the Ryan White CARE Act on the Availability of HIV/AIDS Services

This article assesses the extent to which the availability of HIV/AIDS services in the Baltimore and Oakland eligible metropolitan areas (EMAs) increased after receipt of funding under Title I of the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act. Survey data on the availability of HIV/AIDS services in each EMA were collected from samples of organizations at two points in time: 1 year before (1991) and 1 year after (1993) the Oakland and Baltimore EMAs received their first installments of CARE Act Title I funds. Cross-sectional and longitudinal analyses of the data were performed to assess changes in the availability of HIV/AIDS services. The results showed that after CARE Act Title I funding became available, the availability of ambulatory medical and social support services in the Baltimore and Oakland EMAs increased. However, the way service availability increased varied significantly, reflecting differing opportunities and constraints present in each community. In Baltimore, the increase in the availability of HIV/AIDS services was due largely to the creation of new organizations that used Title I funds to provide services (system expansion). In Oakland, relatively few new organizations were created, but existing organizations added new HIV/AIDS services (service line expansion). Our data also indicated that in both EMAs the majority of HIV/AIDS organizations receiving Title I funds expanded the capacity of their existing services to meet growing demand.
