The special requirements for HIV-prevention programmes by armed forces or insurgency groups in very poor countries that are in active conflict have not been well described. Customary military programme components include: education on sexually transmitted diseases, condom distribution, and HIV testing. Programmes for these armed forces must address: a command structure that may not prioritize this activity, severe resource and logistical constraints, weak health systems for treating sexually transmitted illness, beliefs in traditional medicines for symptoms of sexually transmitted illness, illiteracy that diminishes the utility of educational pamphlets, rape and sexual bartering by soldiers, battlefield transfusions, tattooing and the co-epidemic of tuberculosis.

Some denialists, widely reviled, contend that HIV does not cause AIDS. Other denialists, widely respected, contend that HIV transmits so poorly through trace blood exposures that iatrogenic infections are rare. This second group of denialists has had a corrosive effect on public health and HIV programmes in sub-Saharan Africa. Guided by this second group of denialists, no African government has investigated unexplained HIV infections. Denialists have withheld and ignored research findings showing that non-sexual risks account for substantial proportions of HIV infections in Africa. Denialists have promoted invasive procedures for HIV prevention in Africa – injections for sexually transmitted infections, and adult male circumcision – without addressing unreliable sterilization of reused instruments. By denying that health care causes more than rare infections, denialists blame (stigmatize) HIV-positive African adults for causing their own infections through sexual behaviour. Denialism must be overcome to ensure safe health care and to combat HIV-related stigma in Africa.

The condom is the only known method that provides simultaneous protection against unplanned pregnancy and some sexually transmitted infections (STIs), including HIV, among sexually active people. Using data from the Demographic and Health Surveys from 18 Sub-Saharan African countries, this study examined condom use and reasons for using the method at last intercourse among sexually active young men aged 15 to 29. Most young men were aware of the condom (73%-98%), but its use at last intercourse was quite variable, ranging from 6% in Madagascar to 74% in Namibia. In 10 countries, more young men reportedly used condoms for preventing STIs alone than they did for preventing pregnancy alone. In 6 countries, at least one third of the users used the method for both purposes. Use of the condom at last intercourse was associated with union status, education, residence, and exposure to television in at least two thirds of the countries.

We create a dynamic network model to replicate more closely the population network structures of interest. Network, Norms and HIV/STI Risk Among Youth (NNAHRAY) is a community relationship survey data set, which provides a rare sample of a human risky-behavior contact network. Combining disease compartmental models with our dynamic network model, we simulate the spread of Human Immunodeficiency Virus (HIV) and Herpes Simplex Type 2 Virus (HSV2) with consideration of HSV2's synergistic impact on HIV's transmission. Our model reproduces HIV prevalence, HSV-2 prevalence, and the contact network close to those observed in NNAHRAY, with HIV annual prevalence closer to the estimated values from the literature than those of any disease spread model based on static networks. The success of fitting our model to the target data shows the importance of considering the data sampling process, contact dynamics, and contact network structures. Our model, under certain conditions, has prevalence prediction results that are insensitive to changes in network size. The analysis of various prevention/intervention strategies targeting different risky groups gives important insights into strategy prioritization and illustrates how our model can be used to assist in making public health policy decisions in practice, both for individual diseases and in the more-recent area of study that considers synergy between two diseases.

The aim of this thesis is to propose suitable mathematical models for the analysis of sexually transmitted disease epidemics. We are interested in a closed population, where infections are only transmitted through heterosexual contacts. The population is hence divided into two groups: male and female. Individuals are classified according to gender, relationship and disease status. Both stochastic and deterministic SIS models are employed. The stochastic models are formulated in terms of a Markov process with a finite state space. Two main models are constructed and quantities of interest such as the basic reproduction number and endemic level of the sexually transmitted disease (STD) are obtained. The first model is formulated to describe dynamics of STDs, where the sexual behaviour is considered “faithful”. By being faithful, we mean individuals are monogamous, and there are no casual sexual contacts (one-night stands). The early stages of the epidemic are approximated by a 2-type branching process. This allows us to compute the following quantities of interest, the threshold parameter (R0) and the probability of extinction. In order to study the endemic level, it is helpful to use the deterministic (ODE) approximation of the stochastic SIS epidemic. The behaviour about the endemic equilibrium is studied using an Ornstein-Uhlenbeck process. Stochastic simulations are utilised to obtain the mean time to extinction. The second model is an extension of the first model, where casual sexual contacts (one - night stands) are included in the model. The model is again a Markov process but its analysis is more involved. A key difference is now a 5 type branching process is used to approximate the initial stages of the epidemic, to determine the threshold parameter (R0) and the probability of extinction. Other quantities of interest are studied through similar approaches. Medication use is studied as a control measure in this thesis. We introduce a new parameter (v) governing the medication use into both models. Throughout we study the effect of the control strategies on the key quantities of interest highlighted above.
Wingo, Michelle L. "SOCIAL UNDERDEVELOPMENT IN SUB-SAHARAN AFRICA." Master's thesis, University of Central Florida, 2001. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/4365.
For the past thirty years Africa has produced a more noticeably inferior reserve of human capital than other developing regions. This is puzzling because at the inception of independence, the future of Africa looked promising. However, during the 1970s both the political and economic situation in Africa began to deteriorate, and since 1980, the aggregate per capita GDP in sub-Saharan Africa has declined at almost one percent per fiscal year. Thirty-two countries are poorer now than they were twenty years ago, and sub-Saharan Africa is now the lowest-income region in the world despite the fact that during the last two decades Africa has attracted more aid per capita than other developing regions. I hypothesize that focusing primarily on economic growth as the primary means of development has undermined and deterred social development in sub-Saharan Africa. I believe that as foreign investment and debt increase, social development stagnates and even declines. I argue that because of the focus on economics and lack of focus on social and cultural considerations sustained economic growth has been devitalized in sub-Saharan Africa. For this research I employed time-series, cross-sectional regression analysis to test the relative importance of the economic development model on social development in sub-Saharan Africa. My analysis of the forty-eight countries over thirty years gives leverage to the critique of economic growth centered development policies.

We study three topics on corruption that are of particular relevance to sub-Saharan Africa. Firstly, we address the question of why corruption is such an endemic problem in sub-Saharan Africa. Is it policy driven or "destiny"? We analyse indices of perceived corruption and test several theories regarding the causes of corruption. We find strong support for two arguments: Countries with a British heritage are perceived to be less corrupt, while those with a common law system are perceived to be more corrupt. We find weaker support for four further arguments: Countries with good quality institutions and a greater proportion of women in the labour force are perceived as less corrupt. Countries with greater natural resource abundance and with greater trade openness are perceived to be more corrupt. Secondly, we look at the supply side of bribery. Within the public procurement process, we study how a firm's uncertainty regarding the official's corruptibility and rival firms' costs influences the magnitude of the bribe it offers. Due to the illegal nature of bribery, we also explicitly consider different punishment mechanisms for corrupt firms. We find that secrecy leads to lower bribe levels, and that bribery can be completely deterred by either appropriate fixed fines or by firms being fined punitive damages. Thirdly, we investigate whether more corrupt governments receive less aid. We develop a theoretical framework that treats corruption as a tax on aid. Although we are unable to empirically test this model, we use it to motivate our empirical analysis of aid receipts using data on sub-Saharan Africa. We find a negative correlation between a country's perceived level of corruption and its aid receipts. However, we find no causal effect of perceived corruption on aid receipts. We revisit the results of an influential paper in the literature and find that their result of no evidence that countries perceived as more corrupt receive less aid is not robust to a sample of sub-Saharan African countries, although we find no evidence of a causal effect. We find no evidence that the impact of perceived corruption on aid receipts differs across sectors.
Buchholz, Kathleen B. "Energy Justice in Sub-Saharan Africa." Thesis, The American University of Paris (France), 2002. http://pqdtopen.proquest.com/#viewpdf?dispub=1527235.
Sub-Saharan Africa has the lowest rates of electrification and some of the worst education statistics worldwide. In the absence of strong infrastructure for a reliable grid system and quality universal primary schooling, the poor suffer significantly. Though substantial research has been done on both issues separately, the relationship between the two has yet to be explored. This thesis uses social justice theories to introduce the connections between energy poverty and an individual’s education capabilities through a case study in Zambia. Case study research was carried out in the urban low-resource settlements of Lusaka, Zambia over a period of two months with Lifeline Energy, using methods of participant observation.
Drawing on trends discovered in survey responses, interviews and feedback from a distribution of renewable technologies, this study demonstrates that a lack of modern forms of energy detracts from education. By synthesizing the data with Martha Nussbaum's capabilities approach and Sendhil Mullainathan and Eldar Shafir’s scarcity theory, the research reveals that energy poverty hinders an individual’s ability to study and gain a quality education and diminishes their available cognitive capacity to learn by tunneling attention to the resource deficit. Furthermore, it supports the claim that energy poverty is not gender neutral. The research concludes that the scarcity caused by energy poverty can be lessened by the investment in and use of small-scale renewable technologies which alleviates some of the daily stress and grind of poverty. This thesis lays the groundwork to recognize energy poverty as an injustice.

This thesis brings together 118 published studies on the microbiology of sexually transmitted diseases resulting from work performed in the University of Edinburgh Department of Medical Microbiology between 1973 and 1995. The main aim of these studies was to improve microbiological aspects of the diagnosis and management of syphilis and gonorrhoea. The earliest publication on syphilis serology was the first to recommend the use of a specific treponemal antigen test, the Treponema pallidum haemagglutination assay (TPHA) for routine screening. As a result of this study a screening schedule comprising the Venereal Diseases Research Laboratory (VDRL) and TPHA tests was introduced into routine practice in late 1973. Soon the same screening schedule was widely adopted in the United Kingdom and Europe. Appreciating the importance of computerised and automation I validated and standardised a prototype commercial enzyme immunoassay (EIA) as a single serological screening test and demonstrated that this gave a performance comparable to screening with the VDRL and TPHA tests while being suitable for automation and electronic report generation. Screening for syphilis by EIA is now becoming widespread throughout Europe. Because false positive EIA reactions may also show reactivity in the FTA-abs test, immunoblotting was evaluated as a confirmatory test. The possibility of syphilis reactivation and loss of treponemal markers in patients co-infected with HIV were also studied.

Sexually transmitted diseases affect millions of lives every year. In order to most effectively use prevention resources epidemiologists deploy models to understand how the disease spreads through the population and which intervention methods will be most effective at reducing disease perpetuation. Increasingly agent-based models are being used to simulate population heterogeneity and fine-grain sociological effects that are difficult to capture with traditional compartmental and statistical models. A key challenge is using a sufficiently large number of agents to produce robust and reliable results while also running in a reasonable amount of time.
In this thesis we show the effectiveness of agent-based modeling in planning coordinated responses to a sexually transmitted disease epidemic and present efficient algorithms for running these models in parallel and in a distributed setting. The model is able to account for population heterogeneity like age preference, concurrent partnership, and coital dilution, and the implementation scales well to large population sizes to produce robust results in a reasonable amount of time. The work helps epidemiologists and public health officials plan a targeted and well-informed response to a variety of epidemic scenarios.
