This dissertation explores the cultural and socioeconomic factors that influence adult role transitions in Ghana. Guided by a life course theoretical framework, and using a nationally representative survey (2003-2008 Ghana Demographic and Health Surveys), I estimate accelerated failure-time (AFT) log-normal models that control for the potential effects of unobserved heterogeneity due to the possible omission of certain relevant covariates. The models reveal that when the most optimal hazard distribution function is specified in an event history model, the problem of unobserved heterogeneity becomes significantly reduced. Results from both non-parametric and parametric models suggest a convergence in marriage and parenthood timing among contemporary young women and young men in Ghana compared with their older cohort, highlighting the salience of sociocultural timing on individuals’ life course decisions. The study also utilizes qualitative data from 30 in-depth interviews conducted in Aburi in the Eastern Region of Ghana, during the summer of 2010. The qualitative approach complements the survey methods by uncovering the influential role of the religious institution, a growing sense of individualism, as well as an emerging consumerist culture on family formation decisions in Ghana. Overall, the findings from this study indicate that the spread of information technology in the rapidly globalizing world has had differential effects on two birth cohorts in Ghana. / Thesis (Ph.D, Sociology) -- Queen's University, 2013-12-19 15:00:23.689

This thesis investigates whether adoption of partnerships between water utilities and Community Based Organisations (CBOs) in Sub-Saharan Africa can improve water services to informal urban settlements. The study is particularly relevant because over 1 billion of the world's population have no access to clean water supply with many living in urban areas. The lack of adequate resources coupled with insufficiency of conventional approaches has rendered it impossible for urban utilities to deliver sustainable water services to all customers, including the informal settlements. The thesis proposes that partnership between water utilities and CBOs is a viable approach for improving water services to informal settlements. The thesis enhances understanding of the context in which such partnerships could be developed.

This thesis investigates the effects of rangeland management systems on savanna ecosystems under different environmental conditions in Botswana, Southern Africa. The soil sampling and vegetation assessment were conducted in twenty–three transects located in communal and ranching grazing lands across three sites. Pastoralists were also interviewed on vegetation change on their respective grazing lands. Soil texture, pH, bulk density and soil organic carbon differed between sites, but not between communal and ranching lands. Soil organic carbon was positively affected by soil clay content. The herbaceous vegetation composition showed heterogeneity between sites, but Matlolakgang and Xanagas rangelands were in poor condition, particularly the communal grazing land that had high cover of increasers II species. Higher herbaceous biomass was observed in ranches than communal lands and biomass also increased with increasing soil organic carbon. Bush encroachment was observed in communal and ranching grazing lands at Matlolakgang and Xanagas, but not Goodhope. Woody plant cover, density and diversity increased with decline in soil clay content, but not linearly. Pastoralists indicated that herbaceous vegetation compositions had changed in some areas, with increase of unpalatable grass species and bush encroachment especially in communal land. Pastoralists considered bush encroachment a problem as it suppress herbaceous vegetation productivity, but they also considered woody vegetation as a valuable grazing resource. The long-term indicators of ecosystem degradation (soil and woody cover) showed that communal and ranching grazing did not affect the savanna ecosystem differently. This is contrary to assumptions of Tribal Grazing Land Policy of Botswana, which promote ranching as a more sustainable management system. The results revealed that rainfall and soil clay strongly influence rangeland condition. These results have implications for the management policies of communal grazing lands throughout sub-Saharan Africa and in similar arid habitats across the world.

Determining the conditions that lead to the formation of radical Islamist groups will help analysts and policymakers prioritize countries within sub-Saharan Africa that may need monitoring to prevent the onset of indigenous terrorism. This thesis attempts to produce knowledge toward that end by determining causal variables hypothesized to be associated with radical Islamist group formation through inductive analysis. A narrative describing the formation of a known Islamist movement in Nigeria is compared against a narrative describing the conditions in Zanzibar, where radical groups have yet to emerge given different structural conditions. The goal of the thesis is to try and generate an initial understanding of the underlying conditions that cause radical group formation to help tailor U.S. policy goals toward fighting radical Islamist group emergence through prevention.

The role of the financial sector in helping an economy grow has been the subject of debate for a long time. Recently, however, consensus has been reached, through empirical evidence, showing the importance of financial sector development in achieving economic growth (ADB, 2009). Using the Global Financial Development Database (GFDD) model, the study done here will provide an analysis of financial sector development in Sub-Saharan Africa and its effect on economic growth, using data for 40 countries, in the years from 2000-2014. This analysis was done using a cross-sectional regression analysis of countries in Sub-Saharan Africa (SSA) with data provided from the World Bank. The regression shows significantly positive results between economic growth and firms using banks to finance investments, bank cost to income ratio and bank credit to bank deposits, while significantly negative results are shown in financial system deposits and stock market total value traded. However, seeing as financial sector development is diverse and dynamic, these measurements and the regression done here will not provide a comprehensive picture of the state of financial sector development in SSA.

This research contributes to the growing body of research on cloud computing and addresses the paucity of research on cloud computing adoption, as well as information systems (IS) and information communication technologies (ICTs) adoption in sub-Saharan Africa. The research addresses the current state of cloud computing adoption in addition to the issues that can encourage or preclude its use by SMEs in sub-Saharan Africa. Further, the research establishes the extent to which cloud computing adoption stimulates small and medium-sized enterprises (SMEs) in sub-Saharan Africa to contribute to development. A qualitative research methodology with an interpretive viewpoint is adopted for this research comprising of two major phases that involved a total of eighteen small and medium sized enterprises (SMEs) in Nigeria. A pilot exploratory study using grounded theory was conducted in the initial phase and the development and refinement of a conceptual framework for analysis and evaluation was carried out in the second phase. The framework is theoretically grounded in the integration of two distinct theoretical traditions, i.e. institutions theory and the capability approach. This is the first research study that employs such a combination to examine cloud computing adoption. This research examines the expectations of cloud users against their fears together with other related influences to draw conclusions regarding the future of cloud computing usage in sub-Saharan Africa. The research found that SMEs considered issues like security, privacy and trust as playing a role in enabling adoption of cloud computing. This is in contrast with SMEs in the global north where these specific issues are discouraging adoption. The research recommends to policy makers and stakeholders interested in developing the cloud infrastructure in sub-Saharan Africa, that there is the need to be cautious in drafting policies (which are non-existent at present). This is in order not to draft policies and regulations with regard to cloud computing usage that will inhibit adoption. Finally, this research presents an incremental model that is used to analyse how cloud service provision was introduced in sub-Saharan Africa. The novel three-stage maturity model identified the incremental approach to the delivery of cloud services in sub-Saharan Africa which started from (i) no local provision, (ii) cloud brokers promoting foreign cloud service provision and (iii) locally-available cloud service provision over a period of three to four years. This research envisages that, with further development of the cloud infrastructure especially in terms of internet connectivity, and improved awareness, more SMEs will adopt cloud computing as part of their IS/ICT strategy.

It is gradually becoming common knowledge that, natural resources have not been able to make positive impact on economic growth of countries. In that, countries rich in natural resources grow at a slower pace than the resource-poor countries. This occurrence is one of the reasons behind many defections and militant groups against state authority in many resource-rich countries, especially those in sub-Saharan Africa. Using panel data from 1980 to 2010 on 34 sub- Saharan African countries, this paper examines whether institutionalised authority, which is a proxy for state authority, can change the negative relationship between natural resources and economic growth. The key finding is that, institutionalised authority can alter the negative relationship that exists between natural resources and economic growth.

Les pays africains au sud du Sahara ont vu leur nombre de patients sous traitement antirétroviral (ARV) croître de façon rapide depuis 2005. Si l’impact individuel et collectif de cette montée en puissance des traitements est positif dans l’ensemble, les défis demeurent nombreux en termes de dépistage, d’observance, d’adhésion aux soins, de résistance aux ARV, de dépendance vis-à-vis des bailleurs de fonds, et de disponibilité des personnels. Dans ce contexte, la question du moment idéal pour proposer le début du traitement ARV doit être abordée de façon médicale individuelle (quel est le rapport bénéfices/risques individuel à débuter à des seuils différents ?), mais également de façon collective en terme de bénéfices et risques pour la communauté, d’organisation des soins, d’analyse médico-économique, de prioritisation et d’équité. Cette thèse, qui est une thèse de recherche clinique, aborde le premier volet de la question, celui des bénéfices et des risques pour l’individu à débuter un traitement plus tôt. Sur ce sujet, le raisonnement a beaucoup évolué au cours des 15 dernières années. Après l’arrivée des multithérapies ARV à la fin des années 1990, la crainte de la toxicité des médicaments a d’abord incité à une approche prudente, et à recommander le seuil de début à 200 CD4/mm3 chez les personnes asymptomatiques. Cette crainte de la toxicité a conduit au début des années 2000 à essayer de pratiquer des « interruptions programmées » d’ARV, pour tenter d’obtenir le maintien au dessus d’un seuil de 200 CD4/mm3, tout en limitant l’exposition aux médicaments. Nous avons participé à un de ces essais d’interruptions programmées en Côte d’Ivoire, au cours duquel nous avons contribué à affiner les connaissances sur la toxicité des ARV (Moh, Antivir Ther 2005). Les essais d’interruptions programmées ont conduit à constater que : (i) les personnes qui interrompaient entre 350 et 250 CD4/mm3 avaient plus de risque de morbidité sévère que celles qui n’interrompaient pas, (ii) les personnes qui débutaient leur premier traitement avant 350 CD4/mm3 avaient moins de risque de morbidité que celles qui débutaient plus tard (Moh, AIDS 2007), et (iii) dans l’essai d’interruption Trivacan réalisé en Côte d’Ivoire, cette morbidité sévère intermédiaire était plus fréquente que dans l’essai SMART réalisé sur d’autres continents, et avait un spectre différent, dominé par la tuberculose et les maladies bactériennes sévères. Les conclusions de ces essais ont donc été que le traitement ARV devait être débuté beaucoup plus tôt que ce qui était auparavant recommandé, et que ceci était probablement encore plus vrai en Afrique sub-Saharienne que dans le reste du monde. En 2008, nous avons lancé en Côte d’Ivoire l’essai Temprano ANRS 12136, dont l’objectif est d’évaluer les bénéfices et risques d’un traitement ARV précoce avec ou sans 6 mois de prophylaxie par isoniazide (INH) chez des adultes infectés par le VIH-1 ayant entre 250 et 800 CD4/mm3. De Mars 2008 à Juillet 2012, 2076 adultes ont été inclus dans l’essai Temprano, dont le suivi se terminera en décembre 2014. L’état du suivi est bon, et les incidences de morbidité et mortalité actuellement constatées sont conformes aux hypothèses du protocole. La pratique de la prophylaxie par INH s’avère bien tolérée, et la procédure choisie par notre équipe (radiographie de thorax systématique et période tampon d’observation de un mois avant le début de l’INH) apporte une grande sécurité de prescription (Moh, Plos One, manuscrit en révision). Notre équipe a traversé une crise politico-militaire au 1er semestre 2011, qui n’a pas eu de retentissement sur la qualité de l’essai en cours. Cette crise a par contre eu des effets délétères pour les patients sous traitement ARV, puisque les échecs virologiques retardés sont significativement associés au fait d’avoir été sous traitement pendant cette période (Moh, manuscrit soumis). . / The African countries situated in the South of the Sahara have seen their number of patients under antiretroviral therapy (ART) grow rapidly since 2005. If the individual and collective impact of this rise of the treatments is positive overall, challenges remain in terms of screening, compliance, accession to care, resistance to ARTs, dependence on donors, and availability of the staff. In this context, the question of the ideal time to propose initiation of ART must be addressed in the individually medical way (what is the individual benefit-harm ratio to start at different thresholds?) but also collectively in terms of benefits and risks for the community, organization of care, medico-economic analysis, prioritization and equity. This thesis, which is a clinical research thesis, addresses the first part of the question, the benefits and risks for the individual to start treatment earlier. On this subject, the rationale has changed considerably over the past 15 years. After the arrival of ART multitherapy at the end of the 1990s, the fear of drug toxicity first prompted a cautious approach, and to recommend the threshold from beginning to 200 CD4/mm3 in the asymptomatic people. This fear of toxicity led in the early 2000s to try to practice "scheduled interruptions" of ARTs, to try to get the maintenance above a threshold of 200 CD4/mm3, in limiting exposure to the drug. We have participated in one of these trials of interruptions programmed in Côte d'Ivoire, in which we have helped to refine the knowledge on the toxicity of ARTs (Moh, Antivir Ther 2005). Testing scheduled interruptions led to see that: (i) persons who interrupted between 350 and 250 CD4/mm3 had greater risk of severe diseases than those who didn’t interrupt, (ii) persons who started their first treatment prior to 350 CD4/mm3 had less risk of morbidity than those who started later (Moh, 2007 AIDS), and (iii) in trial interruption Trivacan launched in Côte d'Ivoire, this intermediate severe morbidity was more frequent than in the SMART trial carried out on other continents, and had a different spectrum dominated by tuberculosis and severe bacterial diseases. The findings of these trials were that the ART should be started much earlier than was previously recommended, and that this was probably even truer in sub-Saharan Africa than in the rest of the world. In 2008, we launched in Ivory Coast the clinical trial, Temprano ANRS 12136, whose objective is to assess the benefits and risks of early ART with or without 6 months of prophylactic isoniazid (INH) in HIV-1 infected adults with CD4 250 and 800/mm3. From March 2008 to July 2012, 2076 adults were included in the trial Temprano, which follow-up will be completed by December 2014. The state of the follow-up is good, and the impact of morbidity and mortality currently observed are consistent with the assumptions of the Protocol. The practice of INH prophylaxis is well tolerated, and the procedure chosen by our team (systematic chest x-ray and period buffer observation of one month before the beginning of the INH) brings a prescription safety (Moh, Plos One manuscript in review). Our team went through a crisis politico-military 1St half 2011, which had no impact on the quality of the ongoing trial. This crisis has however had deleterious effects for patients under ART, since delayed virological failure are significantly related to the fact of having been under treatment during this period (Moh, submitted manuscript).

Alors que la question du « vivre ensemble » demeure dans le débat public de la société française, cette thèse retrace la formation en région bordelaise des sociabilités corporelles et sportives des immigrés africains subsahariens en période post-coloniale. Ces dernières connaissent une dynamique effective au fil du temps. Si la décennie des années 1960 reste relativement atone en la matière, dès les années 1970, se constituent plusieurs types de sociabilités fondées sur une pluralité de frontières ethno-nationales, nationales, ethniques et générationnelles. Les différents projets migratoires relatifs aux diverses vagues et types d’immigrations, associés à l’influence des liens transnationaux entre les pays d’émigration et la France expliquent prioritairement cette configuration historique. Ce résultat de recherche vient enrichir l’historiographie française de l’objet étudié. Il montre que des logiques communautaires impriment leurs marques aux pratiques corporelles et sportives à l’exception de la descendance qui tend à s’en extraire et atteste que la relation « sport et immigration » n’est en rien linéaire, mais soumise à la complexité des flux migratoires contemporains et à l’implantation durable des populations en présence. / While the question of "living together" is still a central issue in French society, this thesis recounts the creation in the Bordeaux region of social and professional sporting activities among sub-Saharan African immigrants in the post-colonial period. The dynamic of this activity has changed over time. While the 1960s were a relatively quiet period in this respect, several types of sociability based on many ethno-national, national, ethnic and generational interfaces have come to exist since the 1970s. The various projects for immigration associated with several types of immigration waves, together with the influence of transnational links between countries from which the immigrants came and France, primarily explain this historical trend. This research project adds to the French historiography of the subject under study. It shows that the logic of the community has a strong impact on sports and physical practices, with the exception of the descendants of the immigrants who tend to shun this tendency. The findings show that that the relationship between sport andimmigration is by no means linear but is subject to the complexity of contemporary migration flows and to the sustainable settlement of the populations involved.
