Novel approaches to improving domestic solar panel energy yields in Sub-Sahara Africa

Kanyarusoke, Kant Eliab January 2017 (has links)
Thesis (DTech (Mechanical Engineering))--Cape Peninsula University of Technology, 2017. / This thesis contains innovations that could help homesteads in sub-Sahara Africa (SSA) to ‘harvest’ more energy from flat solar energy collection surfaces. The thesis makes the assumption that universal resolution of energy poverty is a long term issue – and may not realistically be achieved using the traditional electrification route of: Fossil fuel/Hydro potential → electricity → transmission/distribution → paid for/free usage. Using a combination of literature search, Transient System Simulation (TRNSYS) modelling and experimental validation, the thesis notes the bi-hemispherical tropical location of most of the region and the abundant solar resource. It therefore advocates extensive use of the resource at home level for both electricity generation, and fluid heating/preheating purposes. Using mathematical models, the thesis critically examines relationships among energy incidence, transformation and yield from a flat surface for both Photovoltaic (PV) and Solar Thermal (ST) usage. It suggests the first set of innovations for the region: the two azimuths installations. The second set uses TRNSYS and Operations Research (OR) modelling to optimise selection of PV equipment meeting a starter–home’s energy loads throughout the region. Recommendations for both sets of innovations are presented in the form of colour coded maps. The third innovation in the thesis is the patented gravity driven, hydro-mechanical solar tracker, a novel solar tracking device in three different operation and control modes. In summary, one patent, 4 journal papers and 5 peer-reviewed international conference papers comprise the work.

Strategizing for Sustaining Small Business Enterprises in Nigeria

Gumel, Babandi Ibrahim 21 March 2018 (has links)
<p> Small business enterprises are important to the economic growth of Nigeria because they make up 97% of the economy and contribute 70% of the country&rsquo;s job opportunity. Notwithstanding the importance of small businesses in the Nigerian economy, 80% fail within the first five years. Based on system theory developed by Ludwig von Bertalanffy, the purpose of this multi-unit qualitative case study was to investigate the strategies owners and managers used to sustain operations longer than first five years. Twelve senior managers of small businesses in Dutse Nigeria participated in an interview. Methodological triangulation of interview questions was used to collect the data. Review of transcribed data and member checking were used to affirm the validity, credibility, and reliability of the study. Ten dominant themes emerged as findings: managers with educational and professional qualifications, skills, and experience; written business and strategic planning; additional financing; commitment of owners; and improved working conditions and good employees manager rapport. Other findings include the use of word of mouth and maintaining a close relationship with top 20% and high spending customers; use of local FM radio stations, social media, and face-to-face contacts marketing; and the use of e-commerce and e-payment platforms. The findings also include the use of support services; and knowledge of seasonality, cutting cost, and financial discipline. Findings might be utilized by small business owners and managers to develop success strategies to sustain operations longer than first five years which might mitigate small business failure. Mitigating small business failure might contribute to the growth of Nigerian economy.</p><p>

Unmet Need for Sexual and Reproductive Health Services| Results from the 2013 Liberia Demographic and Health Survey

Sobiech, Kathleen L. 10 October 2017 (has links)
<p> Although the association between poor sexual and reproductive health (SRH) and sociodemographic indicators has been explored in many resource-poor settings, limited information exists specific to Liberia. The two studies in this document seek to describe unmet need for SRH services using three critical indicators of SRH services: knowledge of HIV status (sexual health); use of skilled provider for antenatal care and delivery (reproductive health); and use of modern contraception when there is a desire to limit or space reproduction (family planning). Data from Liberia&rsquo;s 2013 Demographic and Health Survey (LDHS) was used to summarize individual-level profiles according to key sociodemographic and sexual health characteristics for sexually active women and men aged 15-49 (N<sub>women</sub>=7,787; N<sub>men</sub>=3,426). Frequency distributions from log-binomial regressions show the prevalence of unmet need for sexual health services for women is 51.9% and 72.8% for men; 39.7% for reproductive services (women only); and prevalence of unmet need for family planning is 70.7% for women and 76.1% for men. Results show wide disparities in unmet need for sexual health services by wealth and educational attainment for both men and women. Differences in unmet need for reproductive services were disparate based on educational attainment, wealth, and urban/rural residence. Although the unmet need for family planning is high, the disparities among subgroups is not as dramatic as other unmet needs. Results indicate the need to evaluate the gaps between national policy and service utilization with special attention to subgroups with a high-burden of unmet need.</p><p>

Sub-Saharan Africa and a Crisis of Sustainability| Exploring Wellbeing and the Role of Ecological Economics in Sustainable Development

Walton, Jeff S. 01 July 2017 (has links)
<p> This case study explores wellbeing and sustainable development in rural sub-Saharan Africa &ndash; a culturally and ecologically diverse and vibrant region devastated by colonial and postcolonial injustices that have created persistent and pervasive social, economic, and ecological crises. The growth-oriented capitalist economic model that has shaped the operative understanding of wellbeing and perpetuated the invented reality of underdevelopment also guides large-scale sustainable development efforts that persistently fail to significantly improve wellbeing among rural communities. Ecological economics may provide a paradigm for sustainable development that is culturally, ecologically, and economically more appropriate &ndash; and more effective &ndash; for both assessing and improving wellbeing. Twenty-seven participants from two rural, forest-dependent communities in Cameroon&rsquo;s Southwest Province were surveyed to assess perceptions of wellbeing and social-ecological resilience. These communities are heavily invested in a sustainable agriculture initiative that reflects an ecological economics worldview and key dimensions of community resilience. Results indicate that perceptions of wellbeing are influenced by both gender and occupation, and that the sustainable agriculture initiative positively impacts perceptions of wellbeing for farmers more than non-farmers, and female farmers more than male farmers. This suggests that participation in the program may positively influence perceptions of subjective and community wellbeing. Further study in these communities, and across similar communities may shed light on how ecological economics might provide a practical basis for broadening an understanding of wellbeing and for informing the approach, design, and implementation of sustainable development initiatives.</p>

The role of human rights lawyers in rights based approach to reduction of poverty in Sub-Saharan Africa

Akintayo, Akinola Ebunolu January 2007 (has links)
Magister Legum - LLM / Sub-Saharan Africa is a region where extreme poverty is prevalent in spite of the regions apparent commitment to the philosophy of human rights, in that all fifty-three countries in the region ratified the African Charter in addition to several international human rights instruments ratified by countries in the region. This state of affairs is traceable to the lack of or ineffective enforcement mechanism of the human rights obligations of countries in the region. Too much attention had been given to post facto intervention of human rights in form of judicial enforcement of these rights to the neglect of other effective methods of enforcement which can be employed in addition to curial enforcement of the rights for a more effective result. This neglect and the ensuing increase in poverty level prompted this research which was aimed at identifying additional methods of pro-active rights enforcement mechanism and the roles of human rights lawyers in their utilisation to reduce poverty in the region. / South Africa

The effects of remittances on economic growth in sub-Saharan Africa

16 October 2012 (has links)
M.Comm. / The subject of the growth effects of remittances is characterised by different and conflicting perspectives. While migration optimists believe in positive growth effects of remittances, migration pessimists, on the other hand, challenge this position and claim that remittances have either a negative or statistically insignificant effect on economic growth. Those for remittances argue that remittances have a positive effect on economic growth mainly through subsequent increases in investment capital and human capital. Migration pessimists, however, stress that remittances negatively impact economic growth, mainly, because of inflationary pressures and moral hazards that result in reduced labour supply. Given such contrasting literature, this study makes an attempt to contribute to the existing literature by assessing the growth-effects of remittances in twenty-nine Sub-Saharan Africa countries over the period 1980-2008. The Arellano-Bover/Blundell-Bond GMM one-step estimator is used in the assessment. Empirical results from the study reveal evidence supporting for statistically significant positive growth effects of remittances in Sub-Saharan Africa. The study further reveals that these positive growth effects of remittances in Sub-Saharan Africa happen through the human capital channel. Even when heterogeneity of sub-regions is taken into account, there is still evidence showing positive growth effects of remittances in Sub-Saharan Africa. Results, however, reveal that in West Africa, remittances have a low positive effect on economic growth.

Accountability of child soldiers in conflict situations in Sub Saharan Africa

Fritzen, Johannes January 2010 (has links)
Throughout the world, but especially in the African continent, international, cross-border and national conflicts are ongoing. In the majority of these conflicts child soldiers are involved in various ways. Judicial problems concerning the prosecution of commanders and leaders of armed groups, irrespective of governmental or not are being solved. Thus, underlying concern is left to the issue of accountability of child soldiers. International, Regional and National protection measures provide for certain judicial standards dealing with children under the age of eighteen. In order to fully understand the difficulties arising from the existence of universal binding measurement dealing with the accountability of child soldiers, one has to be aware of the international, regional and national legislative frameworks. In Sub Saharan Africa, especially in Rwanda, Uganda and the Democratic Republic of Congo, governments face various difficulties, such as the implantation process of international protection measures and ongoing conflicts, making it very difficult to examine the status of accountability measures for child soldiers. States have different minimum ages for accountability for child soldiers. Only a process of international co-operation between governments and non state actors can attempt to deal with the accountability of child soldiers. Not only deterrent, but rather restitution approaches and reintegration programmes should be followed in order to bring justice and achieve results in peace processes.

A Quiet Revolution? Youth Perception of State and Church Ideology in Zaire

Romaldi, Christa January 2010 (has links)
This thesis focuses on the power struggle between Mobutu's administration and the Catholic Church as it played out in the realm of education. In particular, it focuses on how state ideology, meaning authenticity and Mobutism, pervaded education through textbooks and teaching materials in 1970s Zaire and how the Catholic Church attempted to resist state ideology through education as well. Discourse analysis was used to determine how state dogma and Church opposition were disseminated to youth via educational materials. Furthermore, I examine how and why youth responded to this power struggle through the examination of painting, music and literature created by the 1970s cohort as they aged. Again, discourse analysis is used to understand the meanings conveyed through the art. Youth, I argue, have rejected Mobutu and his ideologies and remain uncertain, perhaps even suspicious, of the Catholic Church's role in Zaire (Democratic Republic of the Congo).
