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.

This paper is a study of the effects of foreign aid on perceptions of political corruption in Sub-Saharan Africa. In keeping with the consensus on foreign aid effectiveness, this study proposed that Sub-Saharan African countries receiving more foreign aid would be more likely to maintain high levels of perceived corruption. Hypotheses were tested using multivariate regression, controlling for a number of factors which have shown to be influential on perceptions of political corruption. Two models were tested, one to show the regression over a period of nine years, and the other to show the relationship between the foreign aid and perceptions of corruption over one year. The tests resulted in showing a significantly negative relationship over nine years, but foreign aid lost its significance with perceptions of political corruption over one year. The most influential variable on political corruption in both models was the level of political rights in a country, which indicated a significantly negative relationship between the two variables. The paper also looked at Nigeria in a case study focusing on the effects of foreign aid on governance and economic policy environments, corruption being a major factor in both of these. This study resulted in the conclusion that increases in foreign aid paralleled improved perceptions of political corruption, and that Nigeria's reform initiative during the Obasanjo regime (1999-2007) was the major determining factor in this perception shift. Overall, this study supports the consensus that foreign aid given to countries with reform-minded governments is more likely to contribute to the fight against corruption.

Why victimize civilians during civil war? Inspired by my survival of two civil wars in Liberia, I offer a theory of violence against noncombatants during armed conflicts in sub-Saharan Africa. Civil wars in post-colonial sub-Saharan Africa have a typical pattern that can be distinguished with three distinct stages: the "onset" period at the start of conflicts; the "intervention" period, marked by third-party involvement and negotiations; and the "settlement" stage, marked by an interim government with cabinet positions rationed among belligerents. I argue that the causes and motives for violence against civilians vary across these three stages of civil war. In the first "onset" stage, violence against civilians is mainly perpetuated by foreign recruits who lack ties with local populations. Principle-agent and moral hazard problems emerge as foreign recruits, young of age and disconnected from local populations, want to loot and rape civilian populations. In contrast, commanders responsible for these populations have difficulty monitoring and controlling these recruits. The second stage of "intervention" changes the calculus for combating groups, as the bargaining power of each depends on its control of strategic territory, such as ports and airports. Groups with minor territories and weak capacities are incentivized to attack the soft targets of noncombatants, who are sometimes forced to take sides at this stage. At the third "settlement" stage, the distribution of cabinet positions creates rivalries within groups, with disgruntled factions breaking away and resuming conflict. Civilians are caught in the middle, frequently accused of collaborating with the other side, leading to violence against noncombatants, including hostage-taking, as part of the bargaining process. To examine the stage theory of civilian victimization in sub-Saharan Africa's civil wars, I surveyed Liberia's two civil wars that occurred from 1989 to 1996 and 1999 to 2003. I drew on three sources of data to triangulate the causes and motives of violence against civilians: (a) archives, (b) intensive interviews of combatants and civilian victims of these wars, and (c) witnesses' testimonies from the Liberia Truth and Reconciliation Commission (TRC) hearings. These data are used to qualitatively study Liberia's two civil wars, which may be generalizable to other parts of sub-Saharan Africa. It is found that foreign recruits, strategic territories, and political positions in a power-sharing government may have contributed to violence against civilians during the onset, intervention, and settlement phases of Liberia's two civil wars. The research contributes to the general literature regarding violence against civilians during armed conflicts. According to popular opinion, violence against noncombatants is a natural outcome, but this research points out that the causes and motives of violence against civilians can vary in identifiable ways. It shows how civil wars in post-colonial sub-Saharan Africa have a unique pattern associated with foreign intervention and settlements, and these phases may account for varying motives for violence against civilians. Knowing the motivating factors for violence against civilians can help protect vulnerable populations during armed conflicts, including refugees, internally displaced persons, migrants, and victims of human trafficking. Intervening governments can make more significant efforts to protect civilian populations during the intervention phases and be more sensitive to the dangers sub-group actors pose in distributing government positions during the settlement phases of these wars.

Introduction and Justification: Diarrheal disease is a leading cause of death in children in low- and moderate-income countries. Food, food waste, and water are all vehicles that can promote the spread of diarrheal disease-causing bacteria like Campylobacter, Salmonella enterica, and E. coli. Resistance to commonly used antibiotics is on the rise, making them difficult to manage. This study aimed to determine prevalence and antibiotic resistance profiles of Campylobacter, S. enterica, and E. coli isolated from food, food waste, and water samples obtained from the Chobe Region of Botswana. In addition, the survival of two common pathogens, E. coli and C. jejuni, on kale, a type of leafy green commonly consumed raw, was determined. Methods: Samples were collected from the Chobe region of Botswana in 2022 including water from the local river, food (produce, beef, pork, and poultry) from local vendors, and food scraps from the landfill. Food samples were enriched in the appropriate selective media: Brilliant Green Bile Broth for E. coli, Bolton Broth for Campylobacter, and Rappaport Vassiliadis Broth for S. enterica. Water samples were collected using modified USEPA methods1103.1 and 1604, E.coli isolation was performed by plating on RAPID E.coli2 agar and incubation at 37°C for 2h and 44°C for 16-22h. Campylobacter, S. enterica, and E. coli were isolated from meat, poultry, and water samples before being sent to Virginia Tech, while enriched bacterial pellets from the produce were shipped for screening and isolation at Virginia Tech. E.coli were confirmed by PCR detecting the phoA gene (all E. coli), and classified as pathogenic through screening for the eae (present in enterohemorrhagic and enteropathogenic E.coli), stx1 and stx2 (present in enterohemorrhagic E. coli) and est1b ( present in Enterotoxigenic E.coli) genes. Campylobacter isolates were confirmed using a genera-specific PCR while S. enterica isolates were confirmed using invA primers. These enrichment and primer sets were tested as part of a study to determine the survival of E. coli O157:H7 and C. jejuni on kale during a 21-day shelf life. E. coli and S. enterica isolates were subjected to antibiotic resistance testing using the Kirby-Bauer Disk Diffusion method. Results: Methods for detection of inoculated E. coli O157:H7 on kale indicated survival for the majority of the shelf-life (up to 19 d), in comparison, C. jejuni was undetectable by day 13 using enrichment and PCR or plating. From the Botswanan samples, E. coli was isolated from 20% of produce, 49% of meat, and 84.7% of water. Salmonella was only isolated from produce samples (2.4%, 7/294). Resistance was uncommon among the Salmonella isolates with only one isolate being resistant to chloramphenicol. No Campylobacter were isolated from the screened produce, meat, or food waste. E. coli resistant to 3 or more classes of antibiotics (MCR) were identified in 15.5% of produce, and 22.2% of meat isolates. Isolation of E. coli or Salmonella from meat was not associated with a particular food type. In contrast, isolation of E. coli was more common from certain types of vegetables and fruits. Antibiotic-resistant E. coli were isolated more commonly from beef, poultry, and pork than from produce. Multi-class resistant E. coli were isolated from fruits, greens, soil associated, and above ground associated vegetables, beef, and poultry. Water samples were collected from the same time period as the food samples. E. coli isolation, especially pathogens (based on eae presence) was more frequent from environmental water samples collected during the wet season compared to the dry season. Water samples collected during periods of increased rainfall were more likely to contain E. coli isolates, especially pathogens. S. enterica and Diarrheagenic E. coli isolates, especially MCR isolates, pose a significant risk of illness to consumers. Strategies to reduce the circulation of these pathogens in foods and water sources are needed. / Master of Science in Life Sciences / People can get sick with diarrheal diseases after consuming contaminated food and water. These illnesses are difficult to treat and control when the bacteria causing them are resistant to antibiotics. Campylobacter, Salmonella, and diarrheagenic E. coli are three types of bacteria that can cause illness from food and water. These illnesses disproportionately affect people, especially children, in low-and moderate-income countries like Botswana. Little is known about the prevalence of Campylobacter, Salmonella, and diarrheagenic Escherichia coli in Botswana. This study aimed to determine the prevalence of these microorganisms as well as how resistant they are to different types of antibiotics. Samples from produce, beef, poultry, pork, and recreational water sources were collected in the Chobe region of Botswana over the course of 2022. Food samples were collected from different vendors and food scraps were obtained from the landfill. E. coli and Salmonella were isolated out of meat and water samples in Botswana while produce samples were shipped as mixed cultures to Virginia Tech where E. coli, Salmonella, and Campylobacter isolation or confirmation was done. Once the target bacteria were isolated, their resistance to certain antibiotics was tested. Salmonella was only found in produce from samples collected during October-December. No Campylobacter was found from produce, meat, or food waste. More E. coli was isolated from fruit or vegetable food waste collected from the landfill than from produce bought at local vendors. E. coli was obtained from meat purchased from local vendors more often than samples from the landfill. E. coli was found more often in water when there was more rainfall. E. coli that causes illness was also more likely to be obtained during the wet seasons. Resistant E. coli that could not be killed by the screened antibiotics, were classified as multi-drug resistant when it was resistant to more than three antibiotics. Rainfall, season, and the food source influenced if E. coli isolates were likely to be multi-drug resistant. While more research is needed to determine how these bacteria are moving in the environment and gaining resistance to antibiotics, the findings of this study show they are present in the environment and require further research.

One of the historically marginalized populations in the United States (US) is the Black population. This marginalization extends into higher education, where Black students are underrepresented and continue to experience challenges, especially at Predominantly White Institutions (PWI) and in science, technology, engineering, and mathematics (STEM) programs. However, the current constitution of the Black population, including Black students in the US, is inherently culturally and ethnically diverse. The Black student population includes domestic US students and various groups of foreign-born students such as Black Sub-Saharan African (BSSA) students whose educational trajectories, outcomes, and experiences are unique based on their cultural orientations. Given the within-group differences in this population, prior research has demonstrated the need to disaggregate the experiences in research among different groups for precise research outcomes. This dissertation contributes to that effort by explicitly focusing on the lived experiences of BSSA graduate students pursuing STEM degrees at a PWI through two studies from an assets-based approach: 1) the meaning BSSA graduate students in STEM make of their lived experience with the campus climate at a PWI, using community cultural wealth as a conceptual framework; and 2) the role of family and other funds of knowledge in the educational trajectories and persistence of BSSA doctoral students pursuing STEM degrees at a PWI. I used different qualitative methodologies across both studies, including a blended case study with tenets of participatory action research in the first study in the first study and narrative analysis in the second. The results of these studies revealed that BSSA graduate students in STEM and at PWIs possessed a variety of assets that enable them to resist challenges and persist in their education. Second, the educational environments were not holistically supportive of students. Finally, there was a lack of cultural awareness and validation of students' assets and ways of knowing. The results offered implications for the BSSA graduate students in STEM in the US, scholars, practitioners at PWIs and in STEM departments who work with them, especially in creating inclusive and supportive academic environments. / Doctor of Philosophy / One of the underrepresented populations in the United States (US) is the Black population. The underrepresentation of the Black population extends into universities and colleges. Black students are underrepresented and continue to experience challenges, especially at White populated institutions (PWIs) and in science, technology, engineering, and mathematics (STEM) programs. However, the current body of the Black population, including Black students in the US, is made of many internal groups with different cultures and ethnicities. The Black student population includes domestic students from the US and other groups with international backgrounds who migrate to the US, such as Black students from Sub-Saharan Africa (BSSA), whose educational paths, performances, and experiences are different based on their cultural background. Given the internal group differences in this population, prior research has advanced the need to separately engage with the experiences among the different groups for specific research results and services for each group. This dissertation contributes to that effort by only focusing on the lived experiences of BSSA graduate students pursuing STEM degrees at a PWI through two studies on BSSA students' assets: 1) the meaning BSSA graduate students in STEM make of their lived experience with the campus climate at a PWI, using community cultural wealth as a conceptual approach; and 2) the role of family and other wealth of knowledge in the educational journeys and success of BSSA doctoral students pursuing STEM degrees at a PWI.

The results of these studies showed that BSSA graduate students in STEM and at PWIs possessed a variety of assets that enable them to resist challenges and persist in their education. Second, the educational environments were not entirely supportive of students. Finally, there was a lack of cultural awareness and support of students' assets and ways of learning.

Ellen Johnson Sirleaf of Liberia is the only woman in Africa that has ever been voted into presidential office. Uncovering the dynamics perpetuating men's continued dominance in presidential office-holding in this region requires a deeper understanding of presidential candidacies particularly as they relate to gendered patterns of major party support that often occur due to party gatekeeping. As such, this thesis poses the following questions: How prevalent are women candidates in sub-Saharan African presidential elections? To what extent do women run for major party labels versus minor party labels or as independent candidates? What factors explain those patterns of party representation for women presidential candidates in the region? I hypothesize that women are altogether less likely than men to run for president. When women do run, I posit that they forge minor party candidacies as opposed to major party or independent candidacies. While minor parties may signal legitimacy, consolidate policy platforms, and provide resources for women candidates who face gatekeeping from major parties, they will ultimately be unlikely to propel them into viable candidacies let alone presidencies. Using a mixed methodological approach, this thesis aims to assess ways party representation differs between men and women presidential candidates in 26 sub-Saharan African countries that were considered "free" or "partly free" as of their 2020 elections (Freedom House). As the role of women in democratization continues to be in question, this research is vital to understanding how women are incorporated into the politics of new democracies. / Master of Arts / Ellen Johnson Sirleaf of Liberia is the only woman in Africa that has ever been voted into presidential office, likely because women face disadvantages in gaining political party support. While major parties have significant dominance over minor parties, minor parties may be more likely to support women due to discrimination from major parties. As such, this thesis poses the following questions: How prevalent are women candidates in sub-Saharan African presidential elections? To what extent do women run for major party labels versus minor party labels or as independent candidates? What factors explain those patterns of party representation for women presidential candidates? I hypothesize that women are altogether less likely than men to run for president. When women do run, I posit that they forge minor party candidacies as opposed to major party or independent candidacies. Minor party representation may have important benefits that independent candidacies do not have due to lack of party support. Party representation, even from minor parties, can signal candidate legitimacy, present a clear policy agenda, and provide resources, but minor parties will ultimately be unlikely to propel women into presidencies. This thesis aims to assess ways party representation differs between men and women presidential candidates in 26 sub-Saharan African countries that were considered "free" or "partly free" as of their 2020 elections, denoting their statuses as democracies or at least semi-democracies (Freedom House). I further substantiate the quantitative evidence with evidence from interviews, surveys, and historical context. As the role of women in democracy-building continues to be in question, this research is vital to understanding how women are incorporated into the politics of new democracies.

Yes / Purpose: Although start-ups have gained increasing scholarly attention, we lack sufficient understanding of their entrepreneurial strategic posture (ESP) in emerging economies. The purpose of this study is to examine the processes of ESP of new technology venture start-ups (NTVs) in an emerging market context. Design/methodology/approach: In line with grounded theory guidelines and the inductive research traditions, the authors adopted a qualitative approach involving 42 in-depth semi-structured interviews with Ghanaian NTV entrepreneurs to gain a comprehensive analysis at the micro-level on the entrepreneurs' strategic posturing. A systematic procedure for data analysis was adopted. Findings: From the authors' analysis of Ghanaian NTVs, the authors derived a three-stage model to elucidate the nature and process of ESP Phase 1 spotting and exploiting market opportunities, Phase II identifying initial advantages and Phase III ascertaining and responding to change. Originality/value: The study contributes to advancing research on ESP by explicating the process through which informal ties and networks are utilised by NTVs and NTVs' founders to overcome extreme resource constraints and information vacuums in contexts of institutional voids. The authors depart from past studies in demonstrating how such ties can be harnessed in spotting and exploiting market opportunities by NTVs. On this basis, the paper makes original contributions to ESP theory and practice.

Using feminist theory and comparative analysis, this thesis will investigate why women in sub-Saharan Africa are more vulnerable to HIV/AIDS than men. Among non-governmental organizations and inter-governmental organizations, HIV/AIDS has always been a gender issue because it is clear that women are more vulnerable to the disease, socially, culturally and biologically. Through two case studies -- one on Uganda where the HIV prevalence rate has dropped considerably in recent years, and one on Botswana, where the HIV prevalence rate has drastically increased in recent years â I will shed light on women's vulnerability to HIV, how this vulnerability can be counteracted, and how these counteractive efforts are implemented by women and state governments (if they are implemented at all). It is hypothesized that the empowerment of women may stifle the spread of HIV. / Master of Arts
