The thesis focuses on the problem of Oromo Christianity's lack of indigenous character with special focus on the Ethiopian Evangelical Church Mekane Yesus (EECMY). It examines the methods of mission used by the Ethiopian Orthodox Church (EOC) that introduced Christianity to the Oromo people for the first time. It also examines the methods of mission used by three Protestant mission societies who followed the EOC, evangelised the Wollaga Oromo and established the EECMY. These mission bodies were, the Swedish Evangelical Mission (SEM), the United Presbyterian Mission (UPCNAM) and the Hermannsburg Mission (HM). The Study seeks to investigate whether the four above mentioned Christian mission bodies' methods of mission contributed to the Oromo Christianity's lack of indigenous character. Moreover, the study examines whether the apparent language of worship problem within the EECMY has historical root linked to the mission methods. It is the emphasis of the researcher of this study that the Christian mission methods used to evangelise the Wollaga Oromos were generally inadequate due to missionaries' lack of sensitivity to the culture. The study calls the EECMY to revise her traditional methods of mission that she inherited from the missionaries and root her message within the culture of the Oromo people. Christianity must identify with certain norms and values of Oromo culture. This can be done through contextual model of evangelism. Out of different sub models of contextual theology, this study suggests inculturation model as a method for incarnating the Church in the culture of the Oromo people. It is the writer's belief that inculturation model may be answer to the Oromo Christianity's lack of indigenous character and the apparent problem within the EECMY. Also inculturation can be helpful method in reaching out the non-Christian Oromos with the Gospel. Though the study focuses on the Oromo Christianity and the EECMY, the question and the problems concerning Christianity's being foreign to the culture might be similar in many Churches in the entire Ethiopia and also in Africa.

The overall aim of the research described in this thesis was to evaluate the effect of vitamin A supplementation on respiratory health, assessed by lung function in children aged 6--9 years. It comprises three studies. / The first study determined the magnitude of vitamin A deficiency in the target population in Wukro wereda, Northern Ethiopia. Of the 1339 eligible children identified by house to house surveys, 824 had complete data for vitamin A indicators and anthropometry. Xerophthalmia was detected in 5.8% of the children, 8.4% had serum retinol levels <0.35 mumol/L and 51.1% between 0.35--0.70 mumol/L. Liver vitamin A reserve was also found to be low in 41.0% of the children using the Modified Relative Dose Response (MRDR) and in about 85% of the children, the daily vitamin A intake was below the FAO/WHO basal requirement (<250 RE/day). / The second study found that in comparison with children with adequate vitamin A reserve (MRDR < 0.06), those with low reserve (MRDR &ge; 0.06) had forced expiratory volume in one second (FEV1) 48.8 ml (p = 0.006) lower when unadjusted, 23.1 ml (p = 0.04) when partially adjusted for age, gender and height and 14.1 ml (p = 0.20) when fully adjusted for demographic, general health, lung function and household related characteristics. / The third study describes the results of a randomized controlled trial (RCT) to evaluate the impact of vitamin A supplementation on respiratory health as assessed by change in FEV1 at 4 months. The average change was 53.3 ml (n = 496) and 53.8 ml (n = 501) in the vitamin A and placebo groups respectively. After adjusting for baseline covariates, the difference between them was -3.6 ml (95%CI: -21.6, 14.4). In sub-analysis of the data, gender and vitamin A status subcategories were found to be effect modifiers. / In conclusion, high dose vitamin A supplementation did not show an effect on change in FEV1 at 4 months in children aged 6--9 years with high prevalence of vitamin A deficiency. Sub-analysis findings suggest that the benefits to vitamin A intervention in the study setting can probably be achieved if the other nutritional deficiencies such as zinc are addressed. Moreover, the results also suggest that the effects of vitamin A supplementation on respiratory health status are complex and these need to be taken into account in future studies to assess the clinical and public health implications of vitamin A supplementation in this age group.

Sorghum [Sorghum bicolor (L.) Moench] is a major food security crop for millions of people in sub-Saharan Africa and the fourth most important crop in Africa. The potential sorghum yields are limited due to a number of abiotic, biotic and socio-economic constraints. Among the biotic stresses is the parasitic weed, Striga hermonthica, which inflicts yield losses ranging from 30-100%. Various control options have been recommended to reduce levels of Striga damage. However, these techniques need to be integrated for effective control and to boost sorghum productivity. A series of experiments was conducted to integrate host resistance improvement and the use of a biological control agent, Fusarium oxysporum f.sp. strigae to control Striga hermonthica. These studies were also focused on improving breeders‟ awareness of the traits that farmers‟ desire, on the assumption that farmers‟ variety preference traits are the missing link in technology development and adoption process for S. hermonthica management. The objectives of the study were to: 1) determine farmers‟ views on sorghum production opportunities; threats; indigenous knowledge and perceptions; breeding priorities; Striga infestation; and the coping mechanisms of farmers in the north eastern and north western Ethiopia, 2) evaluate sorghum genotypes for compatibility to F. oxysporum inoculation where grown in Striga infested soil in controlled environments, 3) determine field responses of sorghum genotypes and F. oxysporum compatibility for integrated Striga management (ISM), 4) determine the variability present among selected sorghum genotypes exhibiting S. hermonthica resistance, and compatibility with the biological control agent using phenotypic and simple sequence repeat (SSR) markers, 5) identify F. oxysporum compatible sorghum parents and hybrids with high combining ability for grain yield, yield components, and Striga resistance for ISM, and 6) undertake farmers‟ participatory assessment, and identify their preferred traits for sorghum genotypes under ISM, simultaneously with the breeders‟ evaluation. A participatory rural appraisal (PRA) research was conducted involving 315 farmers in nine districts of three administrative zones within two provinces in Ethiopia. Sorghum landraces were preferred by >85% of participants rather than previously improved released varieties. The participating farmers listed and prioritized their sorghum production constraints. In the North Shewa and North Wello zones drought was the most important constraint, followed by Striga. In the Metekel zone Striga was the number one constraint followed by a lack of genotypes with high grain quality. Controlled environment experiments were conducted involving greenhouse and laboratory tests in order to evaluate 50 sorghum genotypes for their compatibility with F. oxysporum and for possible deployment of the bio-control agent to control Striga. Striga population was reduced by 92% through the application of F. oxysporum, resulting in yield increment of 144%. Twelve sorghum genotypes were identified as promising parents for breeding and to control Striga through integration of host resistance and F. oxysporum seed treatment. During field and sick plot plot evaluations differential responses to F. oxysporum application among the sorghum genotypes were observed for various attributes including Striga plant height. Most traits showed highly significant (p<0.001) genotype X site interactions. Similarly, the main effects of F.oxysporum application were highly significant (p<0.001) across sites for most of the traits. The genotype and genotype X environment biplot identified 13 genotypes that consistently performed well following Fusarium application. The variability present among 14 selected sorghum genotypes exhibiting S. hermonthica resistance, and compatibility with a biological control agent, Fusarium oxysporum, were determined using phenotypic and 20 polymorphic simple sequence repeat (SSR) markers. Highly significant (p<0.001) differences were detected among genotypes for phenotypic traits. Principal component analysis showed three components that accounted for 73.99% of the total variability exhibited among genotypes. Cluster analysis allocated the genotypes into two major groups, one with a further two subgroups based on morphological traits, showing clear demarcations between the genotypes. The SSR markers revealed high levels of polymorphisms among genotypes, with the mean number of alleles per locus being 6.95 and the mean polymorphic information content being 0.80. The observed genetic diversity was relatively wide, with the allele sizes ranging from 203.6-334 bp. The SSR markers allocated genotypes into two distinct clusters close to the phenotypic markers. Forty sorghum hybrids were developed through a line by tester mating design involving 10 lines selected for their compatibility with F. oxysporum and high agronomic performances and four Striga resistant tester parents. The F1s and their parents were field evaluated with complementary in-vitro tests. Field evaluations were conducted at two locations: Kobo and Shewa Robit in Ethiopia, which are well known for their severe Striga infestation. Significant (p<0.05) general combining ability (GCA) effects were observed among testers and lines at both sites for days to 50% flowering and maturity, plant height, biomass, number of Striga plants and Striga plant height. Furthermore, significant (p<0.05) specific combining ability (SCA) effects were detected for days to 50% flowering, biomass, grain yield and number of Striga plants. From the complementary in-vitro experiment, highly significant variation (p<0.01) was exhibited due to line x tester interaction for maximum Striga germination distance. The study identified paternal parents with high GCA effects including SRN-39 and Birhan and maternals 235761, 2384443, IC9830, 235466, 237289,235763, and 235929 to be useful for breeding for ISM in sorghum. At Kobo, cross 235763 x N-13 and Shewa Robit IC9830 x SRN-39 had significantly negative SCA effects for the numbers of Striga plants. Progenies of these crosses will be selected in the Striga resistance breeding program. In the participatory sorghum genotypes assessment, farmers were invited to assess and select the genotypes based on their preferences at maturity and harvesting. The standard agronomic traits and Striga parameters relevant for breeding were collected by the breeders. Earliness, Striga resistance, high yield and high grain quality and threshability were the most important farmers‟-preferred traits for sorghum genotypes. Comparative analyses between farmers‟ and breeders‟ evaluations revealed highly significant correlations (p<0.01) except between Striga resistance and Striga damage and pest resistance and insect damage. Repeatability of scoring genotypes among farmers was consistent (>0.80) for all traits except Striga and pest resistance. The prioritized traits through farmers‟ participation are important for further breeding program. Overall, the study established farmers‟ preferred traits, the effectiveness of ISM to boost sorghum productivity, and identified useful parents and crosses for effective sorghum breeding to control Striga in Ethiopia. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

The main purpose of this study is not only to prove the impact of loan interest rates on the poor in the case of Tigray, Northern Ethiopia but also to recommend improvements to address the negative effects of interest rates that could benefit both the borrowers and the lenders. Combinations of quantitative and qualitative analytical tools were used; the data were collected through administration of a questionnaire to a sample of 471 respondents from three regulated MCIs, one cooperative enterprise, and one unregulated NGO. Results were analysed by using SPSS software. A multi-dimensional approach with respect to demand for credit, return on loan, loan repayment, savings, indebtedness, multiple loans, graduation process, and wellbeing was used and results were triangulated to obtain a full picture. The study has concluded that the interest rate in general, primarily charged by DECSI, eroded the envisaged profits that poor borrowers expected to gain. This caused diversified negative impacts on the poor, those who were entrusted to MCIs. It thus brings into question the efficacy of the social responsibility of MCIs. From a simple analysis, it is found that there is a trade-off between servicing the poor with a low loan cost and securing MCIs operational self-sufficiency. Furthermore, the poor are not only sensitive to the loan interest rate but also to the saving interest rate. Therefore, not only access but also the cost of credit and savings matters to the poor. Moreover, the study identified a positive relationship between the financial capacity of MCIs and lending interest rates. Institutions with higher profitability tend to offer lower interest rates on micro loans but not when commercialization is an issue. The study grasped that socially oriented and responsible MCIs can reach the poorest without compromising financial performances, a “win-win proposition”. Finally, the study offers comprehensive recommendations on policy and practice that address potential changes to how MCIs redesign their loan and savings interest rate. The recommendations also address how MCIs develop graduation processes and self-revolving credit scheme frameworks that strengthen pro-poor microcredit modality. Additionally, the study provides a way forward in the design of future microcredit that could help MCIs deliver on their core social mandate. / Development Studies / D.

This convergent parallel mixed methods study based on Social Ecological Model investigated substance abuse among undergraduate university students at one of the universities in Ethiopia. For quantitative strand of study, data was collected from 422 randomly selected undergraduate students. Data were analysed using Statistical Package for Social Sciences version 17. For qualitative strand, face-to-face interviews were conducted with 17 purposefully selected participants directly involved with students abusing substances. The findings revealed that factors at individual, interpersonal, institutional, community and societal levels affect substance abuse among university students. The study also uncovered loopholes in the policies, guidelines, and programme implementations in the prevention, control, and management of substance abuse at the university. Based on the findings, the researcher developed guidelines based on the findings of the study, the critical literature review, and the inputs from the experts who reviewed the guidelines. The researcher assumes that implementation of the guidelines will reduce substance use and substance abuse among university students. / Health Studies / D. Litt. et Phil. (Health Studies)

In this thesis, a mathematical model for HIV and TB co-infection with TB treatment among populations of Ethiopia is developed and analyzed. The TB model includes an age of infection. We compute the basic reproduction numbers RTB and RH for TB and HIV respectively, and the overall repro- duction number R for the system. We find that if R < 1 and R > 1; then the disease-free and the endemic equilibria are locally asymptotically stable, respectively. Otherwise these equilibria are unstable. The TB-only endemic equilibrium is locally asymptotically stable if RTB > 1, and RH < 1. How- ever, the symmetric condition, RTB < 1 and RH > 1, does not necessarily guarantee the stability of the HIV-only equilibrium, but it is possible that TB can coexist with HIV when RH > 1: As a result, we assess the impact of TB treatment on the prevalence of TB and HIV co-infection. To derive and formulate the nonlinear differential equations models for HIV and TB co-infection that accounts for treatment, we formulate and analyze the HIV only sub models, the TB-only sub models and the full models of HIV and TB combined. The TB-only sub model includes both ODEs and PDEs in order to describe the variable infectiousness and e ect of TB treatment during the infectious period. To analyse and solve the three models, we construct robust methods, namely the numerical nonstandard definite difference methods (NSFDMs). Moreover, we improve the order of convergence of these methods in their applications to solve the model of HIV and TB co-infection with TB treatment at the population level in Ethiopia. The methods developed in this thesis work and show convergence, especially for individuals with small tolerance either to the disease free or the endemic equilibria for first order mixed ODE and PDE as we observed in our models. / Mathematical Sciences / Ph.

This study describes the technique and procedures used for the simultaneous determination of elements involved in Instrumental Neutron Activation Analysis, applied to some geological samples as a sensitive and non-destructive tool. Using Isotopic Neutron Source, the delayed gamma-rays emitted due to neutron capture have been applied for the investigation of the elemental constituents and concentrations of major, minor and trace elements in such samples. The experimental investigations were carried out at the scale of researcher's practices at the chosen site by measuring soil/rock nutrient contents from hydrologically isolated farmland/site plots. Using detailed sampling procedures with special precautions, against contaminations, to yield meaningful results, soil/rock samples have been collected from selected areas of East Gojjam, pulverized, homogenized and prepared for irradiation. The samples were properly prepared together with known standards of potassium iodide or cupric sulphate or arsenic trioxide (one /or both at a time), and simultaneously irradiated in to isotopic neutron ux in the same irradiation position. After activation, the samples were subjected to gamma-ray spectrometry, using a high-purity germanium detection system and computerized multichannel analyzer. The gamma-ray spectra from the irradiated samples were measured by high resolution gamma-ray spectrometry with a calibrated germanium detector. Both qualitative and quantitative approach to data collection and analysis were used in order to gain insight into what should be acceptable to the community. The results obtained have a practical interest in view of possible applications to the technology of extraction and exploration of a variety of industrial, metallic, cement minerals, and geothermal energy and coal deposits. These results tend to agree with the lowest values reported in the literature, and the analytical precision is su cient for the determination of the standard deviation of the distribution of all elements in East Gojjam and these results were brie y discussed within the text of this research work. In carrying out the analysis, the best and most convenient method being the Instrumental and /non-destructive Neutron Activation Analysis was adopted, and NAA has matured and attained analytical competence providing not only rapid, quantitative, qualitative, simultaneous, multi􀀀element analysis but also crucial validation support to programmes using di erent analytical techniques. This method of analysis is generally multi-element and experimental conditions can be designed to be non􀀀destructive to the sample, and it plays a leading role among analytical techniques in the eld of environmental research related to human, animal and plant health. Studies of di erent radionuclide and trace elements in the environmental samples are very important for health physics, research and education. Many forms of elements are possible in environmental samples which may be hazardous for human being, animals and also plants. Most of them have the potential for both benefcial and harmful effects / Environmental Sciences / D. Phil. (Environmental Science)

Early diagnosis and prompt treatment is one of the malaria control strategies used to minimize malaria morbidity and mortality. One of the mechanisms to implement early diagnosis and prompt treatment is community access to diagnostic services and effective antimalarial drugs. However, in Ethiopia the health system is underdeveloped and much of the rural population has limited access to modern health services. Therefore, the Ethiopian government introduced the Health Extension Programme(HEP) which is a community-based health care delivery system aimed at accessing essential health services through its health extension workers (HEWs). Involvement of the HEWs in prescribing and dispensing antimalarial drugs is shown to have improved community access to antimalarial drugs. However, there is insufficient knowledge of HEWs compliance to malaria treatment guidelines and patient adherence of patients treated by HEWs. The objectives of this study has been to describe the HEWs practice in malaria treatment, to evaluate adherence of patients to antimalarial drugs, to explore the factors influencing the HEWs malaria treatment practice and patient adherence, and to develop the guidelines to support the HEWs in malaria treatment practice. A qualitative study design was used to study the HEWs practice in malaria treatment along with patient adherence. Data were collected using in-depth face-to-face interviews, focus group discussion and patient medical record review and were analysed according to Tesch’s steps. The study revealed that the HEWs adequately comply with malaria treatment guidelines during diagnosis of malaria, as well as during the prescribing and dispensing of antimalarial drugs. However, there are some factors influencing the performance of HEWs. These are: shortage of diagnostic kit/RDT, shortage of antimalarial drugs, patient pressure to obtain coartem, work load, and community beliefs with regard to antimalarial drugs effectiveness. This study also revealed that the HEWs follow up after treatment of patients and good community support systems improved patient adherence to antimalarial drug use. Factors negatively influencing patient adherence were identified to include: forgetfulness, fear of shortage of drugs, adverse drug effects, duration of treatment, rapid relief of malaria symptoms and inadequate awareness of the consequence of incomplete dosage. Guidelines were developed to support the HEWs in malaria treatment practice with the aim to improve patient adherence to antimalarial drugs / Health Studies / D. Litt. et Phil. (Health Studies)

Since the late eighties, BPR has established itself as one of the attractive radical change management option for coping and adapting to the new competitive market environment and become popular both in the public and private organisations throughout the world . Cognizant of this fact, all Ethiopian public (government owned) institutions including the public financial institutions have embarked on large-scale change projects since 2004 in which Business process re-engineering(BPR) is a central element . This research examined whether implementation of Business Process Reengineering (BPR) projects have improved operational performance of the selected case public commercial banks in Ethiopia by collecting and analyzing both quantitative and qualitative comprehensive data set, using mixed research approach through questionnaires, interviews, observations and review of secondary sources of information. The operational performance measures utilized in this study are cost reduction, speed of service delivery, service quality, customer satisfaction as well as innovation. A total of 837 (84% response rate) questionnaires were returned from respondents of the selected branches and head offices. In addition, in-depth interviews were conducted with eight senior managers of the respective banks, who were also members of their respective banks reform team and were involved in the design and implementation of BPR. The third method that was used to collect qualitative data was personal observation of the selected bank branches in order to measure the speed of service delivery and convenience of the waiting places. The researcher measured the service delivery time of selected busy bank branches for five consecutive days, for half an hour spent in each branch. This study found that the introduction of BPR in the case banks was met with mixed reactions from employees and some managers. The main achievements of BPR were: service delivery time reduced dramatically as a result of the new process redesign and introduction of information and communication technology services(introduction of e-banking); introducing a single customer contact point through employee empowerment to make all the necessary decisions at that point of contact which resulted in improving the satisfaction of employees and customers. The challenge was that resistance from employees and some managers (labelled the initiative as “Blood pressure raiser” due to their assumptions it will result in employee lay off or the change brings increased workloads for some remaining employees without compatible rewards following the new process redesign. The study also revealed that telecom infrastructure and power interruption considered as main problem areas in providing banking services efficiently and effectively through branch net workings. The researcher recommends that for a better BPR design and implementation as well as sustainability of improvement gains in the banking sector, a forum should be established to discuss and share good practices and technology in the banking sector ; establish strong change management offices to continuously assist and monitor results; and continuously involve and communicate key stakeholders in the design and implementation of change initiatives. / Business Management / D.B.L.
