This research was conducted in one of the districts in the Oromia region located in the Central Rift Valley to assess the problem of soil erosion and deforestation and to determine how these drivers of land degradation affect the livelihoods of farmers. The research was a case study undertaken in an identified micro-watershed making use of the questionnaire interview method. A household sample was obtained using a simple random sampling technique; Information interviews were conducted with community representatives, district level experts and development agents who worked in the community. The objective of the research was to assess the levels of soil erosion and deforestation and the impact on the livelihoods of the community. Research methods were questionnaire and direct observation. The results of the study indicated that the effects of soil erosion and deforestation on land productively, agriculture and livestock production at large, had a negative effect on livelihoods of the community members. Recommendations based on the research affirm the necessity to undertake large-scale natural resource management starting with community-based watershed management thereby reducing the impact of land degradation on livelihoods of farmers and ensuring food security and sustainable land management. / Agriculture, Animal Health and Human Ecology / M.A. (Human Ecology)

This study aimed at assessing factors related to male participation in PMTCT in three public hospitals in Addis Ababa, Ethiopia. A quantitative, descriptive correlational design was used to assess correlation between male participation and socio-demographics, knowledge and awareness in HIV/PMTCT, socio-cultural belief, programmatic factors and reported risk. Male partners (n=216) were interviewed and reviews of HIV counselling and testing (HCT) acceptance formats were made. The major findings were 54.5% (n=156) males reported receiving HCT during their visit to partner’s antenatal care. Some 71.5 % (n=677) of women were accompanied to labour wards by male partners; 86.5% (n=208) of males accepted intra-partum HCT; 55.1% (n=216) scored above the mean score (10) on a 15-point scale for male participation. Male participation in PMTCT was found to have a statistically significant but weak correlation with educational level (r=0.193), income (r=0.167), PMTCT knowledge and awareness (r=0.172), socio-cultural belief (r=-0.164) and reported risk (r=-0.23). / Health Studies / M.A. (Public Health)

Stigma and discrimination (SAD) attached to Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) has been recognised as a major obstacle to HIV prevention, treatment, care and support throughout the world. SAD is more devastating when it occurs in health care settings where it is least expected. Health care providers (HCPs) are supposed to provide physical, social and psychological support to people living with HIV (PLWHA) but HIV and AIDS-related SAD has been extensively documented among the HCPs. Different studies have pointed out that there are three major actionable causes of HIV-related SAD in health care settings. These are lack of awareness among HCPs, fear of casual contacts and associating the SAD to immoral behaviour. The main objective of the current study is to determine the magnitude of HIV and AIDS-related SAD and its associated factors in hospitals and then to propose appropriate SAD reduction-intervention strategy in the health care settings. The study employed pre-test-post-test design with non-equivalent control group. Two paradigms were used in this study including quantitative and qualitative approaches. The sampling method for the quantitative part of the study was probability sampling in which the respondents were randomly selected using stratified sampling technique. The study was able to determine the magnitude of HIV and AIDS-related SAD among the HCPs. Moreover, the study has identified the factors that are attributed to the prevalence of SAD in the hospitals. The major factors identified for causing the SAD in the hospitals were sex, age, work experience, low level of knowledge, negative attitudes and percieved risk of HIV infection of some HCPs toward the PLWHA. The intervention made on the respondents in the treatment group was able to reduce the overall prevalence of the SAD among the HCPs. The study suggests that to reduce the SAD, HIV and AIDS-related trainings before and after graduation is critical to improve the knowledge, attitudes and practices of the HCPs. Besides, ensuring the availability of the protective supplies in hospitals is crucial in reducing the fear of HIV infection among the HCPs while providing care for HIV positive patients. Effective implementation of the hospital policies, strategies, guidelines and protocols along with good institutional support is also vital in creating safe and user-friendly hospitals for PLWHA. / Health Studies

My dissertation address is to describe the long distance bus (LDB) transport, its structure, service adequacy and the role it plays in linking the core to the periphery of Ethiopia. The study applied both qualitative and quantitative data analyses. The quantitative data was mainly collected by using questionnaires, from the selected passengers and operators by longitudinal survey, 384 passengers, or 10 %, from each bus took part in the survey. Of these, only 241 questionnaires (63%) were fully completed and used for this analysis. And 6 % of buses or operators (64) were selected by systematic sampling. The routes and towns were also selected by lottery method. The qualitative data was mainly collected by interview. Among these, 5 % (twenty-five) of experts from the City Transport Bureau; the heads of LDB Associations; the owners of LDB; the Federal Transport bureau; and the Mercato Bus terminal. An interview was analyzed based on their own explanations. FGDs were carried out with passengers awaiting departure in the terminal (off-journey). The secondary sources were taken from both the EFTA and Mercato bus terminal dispatch report. The analysis was made mostly by integrating method, and in some cases with separate analysis. Beside with other inferential statistical, Pearson correlation was also applied. The growth rate for level one and level two buses had risen more than 100 % per annum, whereas level three buses showed a decline of 18 % per year. The whole sector shows a 6.6 % growth rate, which is double that of the population growth (2.6 %). The rate of bus dispatch is very high, approximately 38 per day, on the Dessie and Mojo route. The average bus dispatch in all directions is about 32. In terms of service provision and area coverage, level one buses interlink about 23 major towns. Level two buses service more than 70 major towns, and level three more than 110. The highest record of both area and service coverage was occupied by first level buses servicing Dessie, Mekele, Shashemene, Hawassa, and Jimma. On average, the majority of towns are being serviced by one bus, irrespective of their levels. The area and service coverage is thus very high for level three buses, compared with levels two and one. The Dessie and Mojo lines enjoy the highest bus coverage. LDBs typically provide transport for distances of less than 400 kilometres. They contribute towards core to peripheral ties of the nation. This result is expressed by Krugman’s (1991) core-periphery theory. The service adequacy of the industry indicates that above half of the operators would have to wait approximately one hour to pick up passengers and 1 or 2 days per week to get the turn too. This reveals that Levels one, two and three operators are dormant for 1 or 2 days per week. Supply is thus greater than demand, causing the emergence of an informal LDB service. The fact that about 60 % of passengers have to wait for approximately an hour to catch a bus, after collecting tickets, indicates the demand. The buses’ downtimes in order to secure a full load on each departure are positively correlated with bus levels. The LDB provide more for mobility of goods and peoples that can be shape land use and development patterns, and it generate jobs. This enable more for economic growth. Thus, level one is more attractive than other levels. The study identifies the major challenges facing LDB transport. Integration within stakeholders, both internally and externally, is crucial to satisfy the passenger. / Geography / D. Phil. (Geography)

Like many other economic and social activities that are infrastructure-intensive, the transport sector is an important component of the economy impacting on national, regional and local development as well as the welfare of citizens. An efficient transport infrastructure provides a multitude of socioeconomic opportunities and benefits with positive multiplier effects such as better accessibility to markets, employment, education and health. If it is well managed, transport infrastructure transforms the quality of life of residents through dynamic externalities it generates. But when infrastructure is deficient in terms of capacity, efficiency or reliability, it can have unwarranted economic costs due to reduced or missed opportunities. Despite its central role in rural development, little is known about the extent and impact of the various benefits that arise from the development of roads, particularly in developing countries. A large body of literature exists documenting the spatial patterns of socioeconomic development which can be induced by road infrastructure development processes and are in most cases dynamic and temporal. The impacts of a given road infrastructure development can also be analysed at the local, regional or national perspectives. The local impact is expected to be limited to the immediate neighbourhoods of the highway including tukuls, towns and villages to be found on both sides of the road within a distance of 5kms defining the influence zone. Based on this, the main objective of this research is to assess socioeconomic impacts of road infrastructure development of three newly developed highways on their respective surrounding communities 5-10 years after the interventions. Two of the highways are gravel surfaced and one is paved type. The respective study names are: Gendewuha – Gelago road (Corridor 1), Mile – Weldiya road (Corridor 2) and Ginchi – Kachisi road (Corridor 3). Their respective lengths are 165; 125; and 105 kilometres, while the study refers 10 kilometres on both sides of the roads. The study had focused on primary data on selected variables that describe socioeconomic conditions both before and after the intervention by using mixed methods of data collection considering quasi experimental design (QED). The main methods of analysis employed are descriptive and inferential statistics. Models such as: Random model approach and double-difference regression were used. The research had utilized two types of impact analyses (temporal and spatial) for comparison and also tested by using paired sample t tests: First: for each of the three corridors, comparisons between current conditions and the situation before the road intervention and, second: comparing conditions in the zone of influence (ZOI) situated within 5kms with control zone (COZ) situated beyond 5kms which are considered not to benefit much from road improvements during the period covered by the study. The research is based on data collected from 392 household heads, 77 key informants, 69 FGD participants from seven different localities, traffic counts from seven points, physical observations, outputs of GIS analysis utilizing satellite imageries and vast secondary data. The findings show that there are more positive and less negative temporal and spatial socioeconomic impacts generated by the three corridors notwithstanding disparities among the different locations. Accordingly, the paved highway is found to have more powerful positive impacts than the gravel roads, which are of low standards and functioning poorly. The status of truck and bus terminals which should have been integrated in the highway development projects are still underdeveloped with obvious effects on the sustainability of their socioeconomic impacts in the study areas. Furthermore, certain natural and more importantly manmade factors are found to have pre-empted the realization of certain positive socioeconomic impacts to be obtained from road interventions. In a nutshell, the dissertation had proofed the importance of conducting impact evaluation in the study areas by answering the questions of ‘what works and what doesn’t? and what is the extent of the impact?; measuring the impacts and relating the changes in the dependent variables to developmental policies; investigating the positive and negative effects of road development interventions and their sustainability; producing information that is relevant from transparency and accountability perspective; and finally contributing to individual and organizational level learning that can be inspired by conducting impact evaluations from the perspectives of change theory, programme theory and central place theory. These also offer possibilities of informing decision makers as to whether to expand, or improve road development related interventions by way of programmes, projects and policies. Therefore, from the perspective of Transport Geography, it is the primary interest of the researcher to contribute towards filling the aforementioned gaps in the existing body of the knowledge in Ethiopia and elsewhere. / Geography / D.

The adoption of eHealth is very slow despite evidences showing its benefits. This research examines the individual, clinical, technical and organizational challenges for eHealth adoption from healthcare provider‟s perspectives. A cross-sectional study design with a quantitative paradigm was used. The study was conducted on 312 doctors and nurses randomly selected from ten hospitals in Addis Ababa, Ethiopia. Most respondents viewed eHealth positively with no significant differences in terms of profession or gender. Computer skill, workload, patient interaction, management support, cost and infrastructure were the main concerns. Privacy and security were not the main concerns. Knowledge of eHealth applications and utilization was low, even for evidence-based medicine and online databases. Specialists and males were better aware of eHealth applications. The study showed that eHealth acceptance was good. Increasing eHealth literacy was recommended as a cost effective means for improving access to updated information to improve the quality of healthcare. / Health Studies / M.A. (Public Health (Medical Informatics))

The study was aimed at investigating challenges hampering mother-tongue education with special reference to Afan Oromo in the Eastern Hararge Zone, the Oromia Regional State, Ethiopia. The study mainly explored the available learning materials and the skilled teachers in mother-tongue education, attitudinal factors, the extent of stakeholders’ support for mother-tongue education, parents’ education and their awareness about education through mother tongue and parent school involvements. In the study, the researcher used a mixed method approach in which both quantitative and qualitative research designs were employed to corroborate the data obtained through one method by using other methods to minimise limitations observed in a single design. In the quantitative design, survey questionnaires were employed. Accordingly, 634 primary school teachers and 134 students were randomly selected and asked to fill the questionnaires. These quantitative data were analysed through the SPSS software and responses were analysed using the percentages and the chi-square. Qualitative data obtained through in-depth interviews and observations were analysed using thematic approaches. Documents on education policy, constitutions of the country and reports of the Ministry of Education of Ethiopia were also consulted and integrated with the analyses of the data. The study generally suggests unless strong political and administrative supports are given and public awareness about the mother tongue use in education and development is created, the effort to make Afan Oromo the language of education, intellectuals and development may remain fruitless. In this respect, all the stakeholders, intellectuals and leaders must work together to overcome challenges and dilemmas that impede the implementation of mother-tongue education. The practical works on the ground should match with the language policy of the country. Popular awareness raising activities and mobilization of the communities should be carried out carefully to involve all the communities / African Languages

The transformation of rural people and land to urban land and culture is a natural discourse and inevitable process. In the process, more than half of the current world population are living in urban centres. The number of urban centres and their population is rapidly increasing while the situation of integrated development of urban centres and rural areas such URELs for sustainable development have given less attention in agricultural based countries (ABCs). Multi-disciplinary (agriculture and agro-industries) integration, multi-spatial (urban centre and its hinterlands) linkages, multiscalar (micromeso and macro) levels, multi-actors and stakeholders involvement are the noteworthy innovations in the field of development studies. This study mainly focused on URELs for agribusiness and value chains under the development themes of governance and development as well as contemporary debates. Policies, institutional settings and practical implementation strategies of integrated and balanced development discourse of basic sectoral and urban-rural economic linkages (URELs) missed in ABCs such as Ethiopia‟s comprehensive development policy ADLI neglecting the rapidly growing urban centres. Owing to this, this study is designed to examine the challenges and problems, status and agribusiness and efficiencies of URELs for exploring theoretical empirical model for virtuous circle URELs. Methodologically, the study used sequential explanatory mixed methods research and cross-sectional survey design. The sequential approach was quantitative method, qualitative method and integrating the two findings on interpretation and discussion. The findings present truncated BPLs and FPLs of agriculture and agroindustries. It was was mainly due to poor and greater ranges of efficiency from TE, AE and EE for both agriculture and agro-industries, form of government as ethnic-federalism and regionalism, violation of the existing institutional frameworks, dejure-defacto discrminatin, government businesses, policy and institutional settings, lack of R&D, many paradoxical acts and poor resources mobilization and utilization. These problems and challenges are taken as potential opportunities for improvement and new lens of developing empirical model. The overall recommendation lies on creating enabling environment for virtuous circle URELs and integrated regional development using regional development approach, avoiding illegal interventions, import-export balance, proper resource mobilization and utilization. / Development Studies / D.

Intermediate calculus bridges secondary school and advanced university mathematics courses. Most mathematics education research literatures indicated that the conceptual knowledge in intermediate calculus has challenged first year undergraduate mathematics and science learners to a great extent through the lecture method. The content knowledge attained by them has been tremendously decreasing. Negative attitude exhibited by students toward calculus was highly influenced by the lecture method used. Generally, students have not looked at the learning of all mathematics courses offered in universities as normal as other courses. Due to this lack of background conceptual knowledge in learners, they have been highly frustrated by the learning of advanced mathematics courses. Taking the understanding of teaching and learning challenge of conceptual knowledge of calculus into consideration, Ethiopian public universities have been encouraging instructors to devise and implement active learning methods through any professional development training opportunity. The training was aimed to enhance learners’ content knowledge and attitude towards calculus. This is one of the main reasons for the motivation of this study that experimental group learners were allowed to be nurtured by the lecture method in their mainstream class, and then also the active learning intervention method integrated with GeoGebra in the mathematics laboratory class. Only conventional lecture method was used to teach the comparison group in both the mainstream and mathematics laboratory class. The purpose of the study was to explore the Gambari and Yusuf (2016) stimulus of the jigsaw co-operative learning method combined with GeoGebra (JCLGS) on statistics and chemistry learners’ content knowledge improvement and change of their attitude towards calculus. The post-positivism mixed methods tactic was used in a non-equivalent pre- and post-test comparison group quasi-experimental design. The population of the study was the whole freshman mathematics and science degree program learners of two public universities in Ethiopia in 2017. Samples of the size 150 in both the experimental and comparison groups were drawn utilizing two-stage random sampling technique. A questionnaire using a Likert-scale on attitudes and an achievement test were sources used for data collection. Data analysis employed descriptive statistics conducting an independent samples t-test and a Two Way ANOVA for repeated measures using SPSS23. Each of the findings on content knowledge, conceptual knowledge, and procedural knowledge development produced through the TWO-Way ANOVA, respectively as F(1,148)=80.917; 𝜂2=.353; p<.01, F(1,148)=106.913; 𝜂2=.419; p<.01, and F(1,148)=7.328; 𝜂2=.047; p<.01, revealed a statistically significant difference between the treatment and comparison groups from pre-test to post-test. These findings show that the experimental group participants were highly beneficial in developing their content knowledge and conceptual knowledge through the active learning approach and technology-based learning strategy using Vygotsky’s socio-cultural learning theory. The JCLGS learning environment representing Vygotsky’s socio-cultural learning theory modestly influenced the procedural knowledge learning of the experimental group learners’. Although the lecture method affected the comparison group students’ knowledge development in calculus during the academic semester, the impact was not comparable to that of the active learning approach and technology-based learning strategy. The major reason for this was the attention and care given to the active learning intervention integrated with GeoGebra by the researcher, data collectors, and research participants. Overall findings showed that the active learning intervention allowed the experimental group students to considerably enhance their conceptual knowledge and content knowledge in calculus. Learners also positively changed their opinion towards calculus and GeoGebra. The intervention was a group interactive environment that allowed students’ to be reflective, share prior experience and knowledge, and independent learners. As a matter of fact, educators are advised to model such a combination of active learning approach and technology-based learning strategy in their classroom instructional setting and practices. Consequently, their learners will adequately benefit to understand the subject matter and positively change their opinion towards university mathematics. / Mathematics Education / Ph. D.

The United Nations Economic Commission for Africa Library (UNECA Library) has a collection of more than 90,000 electronic information resources and half a million-print collection. These resources are available freely to staff members of the UNECA, United Nations agencies, diplomats, researchers, students and others. The study investigated the utilisation of electronic information resources and the challenges faced by the different users of the Library. A quantitative research approach with a survey research method was applied. The population for the study was 600 users,, out of which 500 were internal users (UNECA and United Nations agencies staff members) and 100 were external users (researchers, students, or non-staff members). From the population, 20% from each category, that is, 120 users were taken as a sample. A webbased questionnaire built on SurveyMonkey was distributed through email to collect data from randomly selected users. The total response rate was 74%. The data were analysed using built in survey monkey analysis software and reported with simple frequency and percentages. The results shows that 92% of the respondents were aware of the availability of the electronic information resources in the UNECA Library. TInstitutional Repository (IR) and e-journals were frequently accessed and utilised. Highly accessed and utilised databases were the Economist, African Journal Online, JSTOR, Ebscohost, ScienceDirect, and Financial Times. 94% of the respondents reported that the electronic information resources were useful, with 84% agreeing that the resources were easy to use. High numbers of the respondents positively agreed that the quality of their output was improved by using the electronic information resources provided by the library. The respondents also indicated that using the electronic information resources have improved their research output, and overall, the resources have increased their performances. The challenges were information overload, access restriction with IP address, lack of training and remembering login credentials. 68% of the users reported that the library services met their expectations. The study recommends the development of strategies for enhancing accessibility and discoverability of the resources, providing information literacy trainings for all users, and finding alternative measures for IP restriction access. / Information Science / M.A. (Information Science)
