Adoption and adaptation of innovationsNdah, Hycenth Tim 01 September 2014 (has links)
Die Studie mit Fokus auf die Übernahme von Fischproduktion und konservierender Bodenbearbeitung (KB) in Sub-Sahara Afrika (SSA) verdeutlicht 1) die Komplexität von Übernahme- und Diffusionsprozessen landwirtschaftlicher Innovationen in SSA, vertieft 2) den Wissensstand zur Diffusion dieser zwei Innovationen und, leistet 3) einen Beitrag zur Entwicklung eines neuen methodischen Ansatzes für den Forschungsgegenstand. Neben der Darstellung der wesentlichen Konzepte und Literatur basieren die empirischen Daten auf semi-strukturierten Interviews, Fokusgruppendiskussionen, Teilnehmerbeobachtung und QAToCA, einem in der Studie entwickelten, partizipativen und expertenbasierten Bewertungsansatz. Die Ergebnisse zeigen, dass Fischzucht – speziell im Fall von Kamerun – eine attraktive Beschäftigung für mittelständische Landwirte ist. Zur weiteren Verbreitung dieser Innovation besteht jedoch Bedarf für 1) zielgerichtete Förderung mittelständischer Landwirte, 2) Verbesserung der Organisationsstruktur der Landwirte, 3) Stärkung des Beratungssystems, und 4) Verbesserung der Forschung für Jungfischaufzucht. Mit Anwendung von QAToCA für die Übernahme von KB zeigen die Ergebnisse i) hohes Übernahmepotential in Malawi, Sambia, Tansania, Kenia – aufgrund positiver institutioneller Faktoren, ii) geringes Übernahmepotential für Simbabwe – bezüglich der instabilen Marktlage, iii) geringes Übernahmepotential in Süd-Burkina Faso – aufgrund der Konkurrenz um Ernterückstände zwischen KB und Tierproduktion, und iv) hohes Übernahmepotential für Nord-Burkina Faso – was sich darauf zurückführen lässt, dass Alternativen zu KB nicht bestehen. Für eine anhaltende Übernahme landwirtschaftlicher Innovationen in SSA zeigt die Arbeit Handlungsbedarf auf für 1) Berücksichtigung des Bedarfs für neue Absatzmärkte, 2) Anpassung von Innovationen an bestehende Managementstrukturen von Betrieben und, 3) Entwicklung von fördernden politischen und institutionellen Rahmenbedingungen auf Dorf- und Regionalebene. / Focusing on adoption of Fish farming and Conservation Agriculture (CA) in sub-Saharan Africa (SSA), this study: 1) partly demonstrate that, the reality of adoption and diffusion of agricultural innovations in SSA is a more complex issue, 2) improve on the knowledge and understanding of diffusion for these two innovations in SSA and, 3) develop and contribute to a new methodological approach in this field of study. Apart from reviewing concepts and relevant literature, empirical data for this work was obtained by using semi structured interviews, focus group discussions and participant observation alongside a participatory expert-based assessment approach (QAToCA) - developed within this work. Results revealed that, Fish Farming especially for the case of Cameroon remains an attractive activity for medium-scale farmers. However for a sustained adoption of this innovation, there is need for 1) targeted support to medium-scale farmers, 2) improving organisational structures of farmers, 3) strengthening the fragile extension system, and, 4) improving research on fingerlings production. Following application of QAToCA in assessing CA adoption, results reveal i) high adoption potential for Malawi, Zambia, Tanzania, Kenya - explained by presence of positive institutional factors, ii) low adoption potential for Zimbabwe - attributed to unstable and less secured market conditions, iii) low adoption potential for Southern Burkina Faso - explained by strong competition of CA with livestock over residue, and iv) high adoption potential for northern Burkina Faso - explained by the fact that farmers have no alternative than to adopt CA. For long lasting adoption of agricultural innovations in SSA, this work calls for 1) addressing emerging needs for new input and output market outlets, 2) adapting innovations to existing management structures of adopting farms and, 3) developing a supportive political and institutional frame condition at village and regional levels.

Attracting, Recruiting, and Retaining Qualified Faculty at Community Colleges in Sierra LeoneBetts, Gloria 01 January 2017 (has links)
This case study was designed to explore policies that were in place to attract, recruit, and retain qualified faculty for 4 community colleges in Sierra Leone. The research was necessitated by the apparent inability of Sierra Leone educators to train and retain faculty possessing the required academic credentials. The research questions were designed to address the policies and strategies used to attract and recruit faculty, better prepare faculty, improve the quality of classroom instruction, and retain qualified faculty at community colleges. The literature review yielded results about the benefits of community colleges in developing countries, thus reinforcing the need for qualified faculty. Case study methodology and open-ended interviews with 12 purposely selected participants were used to ensure trustworthiness and reveal the essential characteristics of how community colleges in Sierra Leone may succeed in faculty attraction, recruitment, and retention. Participants reported that word of mouth solicitation was the primary method for faculty recruitment, and that the top challenge faced by these institutions was fiscal constraints. Although findings from this study are specific to 4 institutions, they may serve as a guide for qualified faculty retention at all community colleges in Sierra Leone, and hopefully bring about social change by improving academic excellence throughout the country.

HIV/AIDS-Related Stigma and Discrimination Toward Women Living with HIV/AIDS in Enugu, NigeriaNnajiofor, Chinyere Fidelia 01 January 2016 (has links)
HIV/AIDS-related stigma and discrimination (S&D), lack of social support, poverty, and gender inequalities have been identified as factors in the increased prevalence rate of HIV transmission in Enugu, Nigeria, especially among women ages 15 to 49 years. Despite the funding of reduction programs, HIV/AIDS-related S&D remain a major driving force in the increased rate of new HIV cases in Enugu. This study addressed a perceived need for behavioral change intervention approaches that span all societal factors to reduce the HIV infection rate in Enugu Nigeria. The study was guided by Goffman's (1963) social S&D theory. The sample was composed of 132 women living with HIV/AIDS WLWHA ages 21 to 54 years, purposefully sampled from the 4 HIV and AIDS comprehensive initiatives care centers in Enugu, Nigeria. Fifteen WLWHA were interviewed and 114 participated in an online survey. The descriptive statistics and a multiple linear regression analysis and comparison revealed a convergent significant relationship between the S&D determinants (social, political, psychological, environmental, and cultural) and HIV/AIDS-related S&D towards WLWHA in Enugu F (4,109) = 45.09, p

Exploring the Economic Relationship Between China and Sub-Saharan Africa : A Study on the Role of Chinese Foreign Direct Investments in Sub-Saharan AfricaPettersson, Axel, Patel, Rushil January 2023 (has links)
This paper adopts a quantitative and qualitative lens, through which we explore the economic relationship between the region of Sub-Saharan Africa and China as a consequence of Chinese Foreign direct investments (FDI). Primarily, the paper’s direction, analysis, and discussions are dictated by the usage of primary and secondary data. Our primary data is constructed as a panel data set including GDP for 38 countries alongside the Chinese FDIs for each country during the period 2003-2021. Our secondary data includes already existing papers on topics related to our purpose and the data found in them. The main points include the economic development of Sub-Saharan Africa, the subsequent enforced Chinese economic policy, and further the gains China see from their strides into the region. In order to prove our hypothesis and research questions we've used econometric models.The panel data was used to conduct several time series regressions, where we further used different models and tests to get the best possible result Due to the fact that our regression shows a significant and positive correlation between economic growth in the region as a result of Chinese FDI, we can establish that past research is reinforced. Through the used model we’re enabled to look at the individual effects of every country in the region. In addition, by comparing these effects with the level of corruption and which type of income group the countries belong to, we can further highlight the fact that China tends to invest in countries who can offer something in return. Examples of such cases could be South Africa and Angola who are two of the biggest receivers of Chinese FDI in the region, which we, throughout the paper, attribute to the fact that they have an abundance of natural resources.

The relationship between stock market returns and inflation : new evidence from Sub-Saharan AfricaMpofu, Bekithemba January 2010 (has links)
The literature investigating the relationship between stock market returns and inflation is long and has produced diverse findings. This thesis examines the nature of stock–inflation relations in Sub-Saharan countries whose stock markets were established before 1992. Evidence in this thesis shows that in the short term there is a positive relationship between stocks and inflation. Using the Johansen (1988) evidence, a long-run stock–inflation relationship is confirmed only in Nigeria and South Africa, where it is found to be negative. However, accounting for structural breaks provides evidence for a long-run relationship in Botswana, Ghana and Kenya. The evidence of the effects of regimes in the relationship is further supported by a nonparametric cointegration analysis which finds a long-run relation in countries where the Johansen (1988) method had failed. Unexpected inflation is also found to be related to stock returns in Botswana, Ghana, Kenya, Nigeria and Mauritius, which raises concerns about the use of month-end stock data in analysing this relationship. The thesis confirms the existence of hidden inflation in Kenya, Mauritius, Nigeria and Zimbabwe. Imported inflation, interest rates and the exchange rate are found to have useful information about inflation movements in Sub-Saharan Africa.

The engineering and optimization of expression of rotavirus-like particles in insect cells using a South African G9P[6] rotavirus strain / by Maria J. van der Westhuizen.Van der Westhuizen, Maria Jacoba January 2012 (has links)
Rotavirus infection causes gastroenteritis, specifically severe gastroenteritis, affecting children younger than five globally, regardless of hygiene and water quality. Current licensed, live, attenuated vaccines do not contain the G9 genotype, which is a prevalent rotavirus strain circulating in sub-Saharan Africa, a region that carries a high rotavirus disease burden. Rotavirus-like particles (RV-VLPs) is an attractive non-live vaccine candidate, which has shown promising results in animal studies. Previously, dsRNA was extracted from a stool sample containing a South African human G9P[6] neonatal strain, and amplified cDNA using a sequence-independent procedure. The consensus sequence was obtained for the genome segments using 454® pyrosequencing. The insect-cell-codon-optimized genome segments 2 (VP2), 4 (VP4), 6 (VP6) and 9 (VP7) were cloned into a modified pFASTBACquad vector (pFBq). Several combinations of the genome segments were cloned to produce double-layered particles (DLP; pFBqVP2VP6) or triple-layered particles (TLP; pFBqVP2VP6VP7). In the current study, a ΔTLP (pFBqdVP2-VP8*VP6VP7) construct was generated. The first 92 amino acids of VP2 are not necessary for the conformation of recombinant RV-VLPs. The ORF of VP8*, which contains immune important epitopes, was fused to the 5’ end of the dVP2 coding region resulting in a dVP2-VP8* fused protein which was expressed in the presence of VP6 and VP7 to produce ΔTLPs. The Bac-to-Bac® Baculovirus Expression System and Spodoptera frugiperda (Sf) 9 insect cells were used for expression. All the proteins were successfully expressed. VP2, VP6, VP4 and the dVP2-VP8* fused protein were visible on Coomassie stained SDS-PAGE. Expression of VP7 could only be confirmed with western blot analysis. Particle formation, as assessed by transmission electron microscopy (TEM), was observed for DLPs. No TLPs of dVP2-8*/6/7 or VP2/6/7 were visualized due to the lower expression level of VP7 and the lack of calcium supplements during the assembly process. In conclusion, it was possible to produce RV-DLPs derived from the consensus sequence determined for a G9P[6] rotavirus directly from stool without prior propagation in cell culture or virus isolation. This strain contains both the G9 and P[6] genotypes that are currently prevalent in sub-Saharan Africa. / Thesis (MSc (Biochemistry))--North-West University, Potchefstroom Campus, 2013.

Die militêre betrokkenheid van die Verenigde State van Amerika in Sub-Sahara Afrika : 1993-2001 (Afrikaans)Esterhuyse, Abel Jacobus 12 February 2004 (has links)
The aim of this study is to investigate and analyse the military involvement of the USA in the security of sub-Saharan Africa (SSA) during the era of the Clinton administration (1993-2001). The study is based on the assumption that the US did not have that much interest in the security of SSA during the Clinton era and that it did not want to become militarily involved in SSA. Its position as the only remaining superpower in the post-Cold War era, however placed a responsibility on the US to be militarily involved in the creation of a more secure SSA. The study relies on two theoretical constructs. On the one hand the changing nature of security in the post-Cold War world in general, but specifically in SSA, serves as a theoretical starting point. This is, on the other hand, supported by a theoretical focus on the nature of military involvement globally, but also specifically in SSA in the era after the Cold War. The latter is to a large extent related to the changing nature of military force and the use thereof in the post-Cold War era. The military involvement of the US in the management of the security of SSA during the Clinton era is analysed against the background of the US interests, policy, and strategy – specifically its security strategy – in SSA. The reality of the absence of concrete US interests in SSA is highlighted. This lack of interest led to a situation whereby SSA could not be a priority in US foreign policy. The US policy objectives in SSA were nevertheless aimed at the promotion of democracy, the improvement of the security situation and the support of economic progress. The reluctance of the US to deploy military forces in SSA underpins its security strategy and military involvement in SSA. The security strategy of the US was in essence preventive in nature since it aimed at preventing the manifestation of threats from SSA against the US by promoting the stability of SSA. However, the US was still militarily involved in SSA in a variety of ways, from the provision of military training and the conduct of military exercises to military operations. Military involvement centred around the empowerment of armed forces in SSA. It was argued that the capacity of the armed forces of SSA should be developed to support democratic governance and economic progress. The capacity building programmes of the US armed forces in SSA concentrated on defence reform, military professionalism, the creation of indigenous conflict resolution and peace support capabilities, the provision of equipment, and the improvement of health and environmental conditions. / Dissertation (MA (Security Studies))--University of Pretoria, 2005. / Political Sciences / unrestricted

A Comparative Study of Institutional Responses to Sustainable Mobility for Public Transport in cities in Ghana and TanzaniaBonsu, Christine 12 May 2023 (has links)
Städte sind aufgrund der zunehmend negativen Auswirkungen des Verkehrs auf die Umwelt an vorderster Front der nachhaltigen Entwicklung und der nachhaltigen Mobilität. In den Städten Subsahara-Afrikas scheinen jedoch die Akteure und Hauptvertreter nachhaltiger Mobilität den Herausforderungen bei der Erreichung nachhaltiger Mobilitätsziele im öffentlichen Verkehr nicht gewachsen zu sein. Vor diesem Hintergrund untersucht diese vergleichende Studie die institutionellen Antworten auf das Erfordernis nachhaltiger Mobilitätslösungen im öffentlichen Verkehr in der Stadtregion Accra (Ghana) und der Stadt Dar es Salaam (Tansania) im Hinblick auf die vorhandenen Kapazitäten der Institutionen, Koordinations sowie Kommunikationsmechanismen. Die Studie folgt einem qualitativen Forschungsdesign und wendet Methoden an, die mit den wesentlichen Grundannahmen qualitativer sozialwissenschaftlicher Forschung übereinstimmen.
Die Ergebnisse der Studie zeigen, dass nachhaltiger ÖPNV in beiden Städten als die Nutzung von Fahrzeugen mit höherer Auslastung, klar definierten lokalen Zielen für nachhaltigen ÖPNV und ganzheitlichen Regulierungssystemen wahrgenommen wird. Die vergleichende Analyse der beiden Städte in Bezug auf das Schlüsselthema Governance zeigt, dass im Fall der Stadt Accra das Fehlen eines Stadtrats mit einem entsprechenden Stadtoberhaupt oder einem Champion wie im Fall der Stadt Dar es Salaam ein wichtiger limitierender Faktor ist, der Entwicklungsprogramme, -pläne und -projekte verzögert. Die unzureichende Koordinierung zwischen den Institutionen wiederum führt im Fall von Dar es Salaam trotz des Vorhandenseins eines Stadtrats zu doppelten Strukturen und zur Zersplitterung der knappen Ressourcen. Folglich werden kurzfristige, mittelfristige und langfristige Strategien für Entwicklungsmaßnahmen in der Stadtregion Accra und der Stadt Dar es Salaam vorgeschlagen. / Cities are at the forefront of sustainable development and sustainable mobility due to the rising negative impacts of transportation to the environment. Actors and key stakeholders for sustainable mobility in cities in Sub-Sahara Africa however seem not ready for the associated challenges towards the attainment of sustainable mobility for public transport. It is against this background that this study comparatively investigates the institutional responses to sustainable mobility for public transport in Accra city-region (Ghana) and Dar es Salaam city (Tanzania) in the light of existing capacity of the institutions, coordination and communication mechanisms. This study adopts the qualitative research design and methodological choices that are in conformity with the ideologies of this design in Social Science Research.
Findings from the study reveal that both cities perceive sustainable public transport as use of higher occupancy vehicles, clearly defined local goals on sustainable public transport and holistic regulation regime. The comparative overview analysis of the two cities in line with the key issue of governance indicates that in the case of Accra city region, the absence of a city council with a respective city head or champion as in the case of Dar es Salaam city is a major limiting factor retarding development programmes, plans, and projects. Inadequate coordination among institutions, on the other hand, results in duplication of efforts and dispersal of scarce resources in the case of Dar es Salaam despite the presence of a city council. Consequently, short term policies, medium term policies, and long-term policies are proposed for development interventions in Accra city-region and Dar es Salaam city.

Financial Analysis and Fiscal Viability of Secondary Schools in Mukono District, UgandaTanner, Janet Jeffery 08 December 2006 (has links) (PDF)
Within the worldwide business community, many analysis tools and techniques have evolved to assist in the evaluation and encouragement of financial health and fiscal viability. However, in the educational community, such analysis is uncommon. It has long been argued that educational institutions bear little resemblance to, and should not be treated like, businesses. This research identifies an educational environment where educational institutions are, indeed, businesses, and may greatly benefit from the use of business analyses. The worldwide effort of Education for All (EFA) has focused on primary education, particularly in less developed countries (LDCs). In Sub-Saharan Africa, Uganda increased its primary school enrollments from 2.7 million in 1996 to 7.6 million in 2003. This rapid primary school expansion substantially increased the demand for secondary education. Limited government funding for secondary schools created an educational bottleneck. In response to this demand, laws were passed to allow the establishment of private secondary schools, operated and taxed as businesses. Revenue reports, filed by individual private schools with the Uganda Revenue Authority, formed the database for the financial analysis portion of this research. These reports, required of all profitable businesses in Uganda, are similar to audited corporate financial statements. Survey data and national examination (UNEB) scores were also utilized. This research explored standard business financial analysis tools, including financial statement ratio analysis, and evaluated the applicability of each to this LDC educational environment. A model for financial assessment was developed and industry averages were calculated for private secondary schools in the Mukono District of Uganda. Industry averages can be used by individual schools as benchmarks in assessing their own financial health. Substantial deviations from the norms signal areas of potential concern. Schools may take appropriate corrective action, leading to sustainable fiscal viability. An example of such analysis is provided. Finally, school financial health, defined by eight financial measures, was compared with quality of education, defined by UNEB scores. Worldwide, much attention is given to education and its role in development. This research, with its model for financial assessment of private LDC schools, offers a new and pragmatic perspective.
