DYNAMICS OF THE HIV EPIDEMICS AMONG INJECTING DRUG USERS AND FEMALE SEX WORKERS IN VIETNAM

Although injecting drug users (IDUs) and female sex workers (FSWs) carry a disproportionate burden of HIV in Vietnam, little is known about the dynamics of the HIV epidemic among these high-risk populations. This thesis involved a secondary data analysis of the ‘2009 HIV/STI Integrated Biological and Behavioral Surveillance’ (IBBS) study to identify the correlates of HIV among IDUs and FSWs in Vietnam. It also involved the creation and simulation of an Agent-based model (ABM) to characterize the dynamics of the HIV epidemics among IDUs and FSWs, and to explore the effects of different intervention strategies. Data collected from 3,038 male IDUs, 2,530 street-based sex workers (SSWs) and 2,768 venue-based sex workers (VSWs) from 10 provinces in Vietnam during 2009-2010 were analyzed using descriptive statistics, bivariate and multivariate logistic regression analyses. An ABM was constructed using key behavioral data from the IBBS study. Different intervention scenarios based upon different levels of behavioral change were then simulated and compared. The aggregated prevalence of HIV infection was 30.6% (n=930) among male IDUs, 10.6% (n=267) among SSWs and 6.7% (n=186) among VSWs. Lifetime needle sharing, duration of drug injection ≥ 5 years, and having regular sexual partners who injected drugs were associated with increased risk of HIV among IDUs. Independent correlates of HIV infection in multivariate analysis, regardless of sex work types, included lifetime injecting drug use, high self-perceived HIV risk, and age ≥ 25 years. Intervention scenarios of lowering needle sharing levels among those who injected drugs resulted in the largest reductions in HIV infection in all simulated populations and across various intervention scenarios of behavioral change. The majority of the reductions occurred when needle sharing levels declined from 50% to 40% and to 30%, respectively. The HIV epidemic in Vietnam requires targeted prevention interventions among populations at high-risk of HIV infection. Results from the thesis suggest drug injection-related risks play an important role in fueling the epidemic and thus underscore the need to strengthen HIV harm reduction services in Vietnam. The thesis demonstrates that the use of ABM well complements traditional epidemiologic regression-based analysis in providing important insights into the complex dynamics of the HIV epidemics among IDUs and FSWs

The Private Life of Public Health: Managing Chronic Disease in an Era of Neoliberal Governmentality

Noncommunicable diseases (NCDs) such as heart disease and cancer account for over half of the global mortality burden, and are the leading cause of death in every region of the world except Sub-Saharan Africa. Despite this, they remain off the analytical radarscope in political science. This silence has been coupled with the tendency of public health researchers to frame NCDs as apolitical--largely a product of an individual's risk behaviors. Such an accounting depoliticizes NCDs, as well as public health approaches to their analysis and prevention. This project's central aim is to introduce a political analysis of chronic disease, demonstrating that public health approaches to NCDs exhibit political rationality. To that end, I explore several questions. How are NCDs accounted in behavioral terms, and how are their risks constructed as apolitical in the public health discourse? Additionally, if public health is presented as a domain of neutral science, how is it that its practices increasingly display market values, including a limited role for the state, a preoccupation with cost efficiency and choice, and the cultivation of the entrepreneurial self who sees her health as a site of investment? To answer these, I employ a discursive approach, specifically Foucault's framework of government rationality, or "governmentality." It is through the deployment of neoliberal governmentality in three spheres - knowledge, power, and subjectivity - that public health reveals itself not a neutral science, but rather one brimming with the values and logic of the private sector. I develop this argument through a critique of the discipline and practices of public health in three cases: the United States, United Kingdom, and Sweden. Despite exhibiting historically different approaches to health and social welfare, all three show a marked manifestation of neoliberal rationality in public health approaches to chronic disease. The consistency of these findings, in addition to the more general features of the public health discourse, thus allow a conclusion that public health approaches to NCDs are not value-neutral, and are indeed a political phenomenon

Unmet goals of tracking: within-track heterogeneity of students' expectations for

Educational systems are often characterized by some form(s) of ability grouping, like tracking. Although substantial variation in the implementation of these practices exists, it is always the aim to improve teaching efficiency by creating homogeneous groups of students in terms of capabilities and performances as well as expected pathways. If students’ expected pathways (university, graduate school, or working) are in line with the goals of tracking, one might presume that these expectations are rather homogeneous within tracks and heterogeneous between tracks. In Flanders (the northern region of Belgium), the educational system consists of four tracks. Many students start out in the most prestigious, academic track. If they fail to gain the necessary credentials, they move to the less esteemed technical and vocational tracks. Therefore, the educational system has been called a 'cascade system'. We presume that this cascade system creates homogeneous expectations in the academic track, though heterogeneous expectations in the technical and vocational tracks. We use data from the International Study of City Youth (ISCY), gathered during the 2013-2014 school year from 2354 pupils of the tenth grade across 30 secondary schools in the city of Ghent, Flanders. Preliminary results suggest that the technical and vocational tracks show more heterogeneity in student’s expectations than the academic track. If tracking does not fulfill the desired goals in some tracks, tracking practices should be questioned as tracking occurs along social and ethnic lines, causing social inequality

COVID-19 Booster Vaccine Acceptance in Ethnic Minority Individuals in the United Kingdom: a mixed-methods study using Protection Motivation Theory

Background: Uptake of the COVID-19 booster vaccine among ethnic minority individuals has been lower than in the general population. However, there is little research examining the psychosocial factors that contribute to COVID-19 booster vaccine hesitancy in this population.Aim: Our study aimed to determine which factors predicted COVID-19 vaccination intention in minority ethnic individuals in Middlesbrough, using Protection Motivation Theory (PMT) and COVID-19 conspiracy beliefs, in addition to demographic variables.Method: We used a mixed-methods approach. Quantitative data were collected using an online survey. Qualitative data were collected using semi-structured interviews. 64 minority ethnic individuals (33 females, 31 males; mage = 31.06, SD = 8.36) completed the survey assessing PMT constructs, COVID-19conspiracy beliefs and demographic factors. 42.2% had received the booster vaccine, 57.6% had not. 16 survey respondents were interviewed online to gain further insight into factors affecting booster vaccineacceptance.Results: Multiple regression analysis showed that perceived susceptibility to COVID-19 was a significant predictor of booster vaccination intention, with higher perceived susceptibility being associated with higher intention to get the booster. Additionally, COVID-19 conspiracy beliefs significantly predictedintention to get the booster vaccine, with higher conspiracy beliefs being associated with lower intention to get the booster dose. Thematic analysis of the interview data showed that barriers to COVID-19 booster vaccination included time constraints and a perceived lack of practical support in the event ofexperiencing side effects. Furthermore, there was a lack of confidence in the vaccine, with individuals seeing it as lacking sufficient research. Participants also spoke of medical mistrust due to historical events involving medical experimentation on minority ethnic individuals.Conclusion: PMT and conspiracy beliefs predict COVID-19 booster vaccination in minority ethnic individuals. To help increase vaccine uptake, community leaders need to be involved in addressing people’s concerns, misassumptions, and lack of confidence in COVID-19 vaccination

An Agent-Based Epidemic Simulation of Social Behaviors Affecting HIV Transmission among Taiwanese Homosexuals

Computational simulations are currently used to identify epidemic dynamics, to test potential prevention and intervention strategies, and to study the effects of social behaviors on HIV transmission. The author describes an agent-based epidemic simulation model of a network of individuals who participate in high-risk sexual practices, using number of partners, condom usage, and relationship length to distinguish between high- and low-risk populations. Two new concepts—free links and fixed links—are used to indicate tendencies among individuals who either have large numbers of short-term partners or stay in long-term monogamous relationships. An attempt was made to reproduce epidemic curves of reported HIV cases among male homosexuals in Taiwan prior to using the agent-based model to determine the effects of various policies on epidemic dynamics. Results suggest that when suitable adjustments are made based on available social survey statistics, the model accurately simulates real-world behaviors on a large scale

EDU-COM 2004 International conference: new challenges for sustainability and growth in higher education

EDU-COM 2004, an international conference held in Khon Kaen, Thailand from the 24th to the 26th November, 2004 took the theme: New Challenges for Sustainability and Growth in Higher Education. EDU-COM 2004 was sponsored and organised by Edith Cowan University, Khon Kaen University and Bansomdejchaopraya Rajabhat University/ The Conference was structured to address five sub-themes pertinent to the challenges facing higher education worldwide: • Collaboration between campus and community in Higher Education • Collaboration targeting multi-cultural and cross-cultural issues in Higher Education • Collaboration through new teaching and learning technologies in Higher Education • Collaboration for quality: valuing and evaluating performance in Higher Education • Collaboration for effective governance in Higher Education Contributors were invited to address on or more of these sub-themes. All papers published in these proceedings reflect the drive for richer learning experiences, improved learning environments and recognition of the importance of the local community as technology enables us to think globally. Predictably perhaps, e-education brought the most substantial response, a clear indication of the perceived potential for new technologies to influence teaching, learning and administration in higher education. The papers also highlight some of the challenges and emerging expectations for higher education in a world that is increasingly characterised by international alliances, partnerships and tensions – a search for sustainability and equity in a period of rapid social and technological change. The Proceedings are in 3 sections. Section 1 – Keynote Speakers; Section 2 – Academic Peer Reviewed Papers: Section 3 - “Work in Progress”. EDU-COM 2004 was attended by delegates from Australia, Botswana, Cambodia, China, Denmark, England, Hong Kong, Iran, Ireland, Japan, Lao, Myanamar, Singapore, Tanzania, Thailand, Vietnam
