The inclusion of students with impairment in higher education needs enabling legal frameworks to lay the foundation for equal opportunities for those learners in all aspects of university life (Shepherd, 2001:17). To this effect, in the past two decades several countries have revised their legal documents in order to promote inclusive education at all levels of schooling. Accordingly, in 2006 the Ethiopian government also developed a new legislative document, namely Special Needs Education Program Strategy, in order to apply inclusive education in regular schools and in higher education institutions. Following the introduction of this policy document, all regular schools and higher education institutions in Ethiopia have been required to implement inclusive education as a mandatory approach when educating students with impairment, including those who are visually impaired. However, the actual implementation of an inclusive approach is being challenged by the social, political and physical circumstances of higher education institutions. Therefore, this study aimed at examining the existing challenges and prospects towards the inclusion of students with Visual Impairment (VI) in the particular context of Addis Ababa University (AAU). The study adopted an interpretive paradigm for better understanding and in-depth interpretation of the inclusion of students with VI at AAU. An interpretive paradigm also informs the detailed judgements made by experts of a suggested action plan for progressively providing support for students with VI at AAU. The study also applied the critical disability paradigm as a complementary philosophical base in order to examine critically the challenges that students with VI face and to suggest ways to transform the inclusive policies and practices of AAU in favour of the students. The researcher undertook a Delphi investigation to address the main aim of this research (i.e. to determine how best to implement an action plan that progressively increases support for students with VI at AAU over a period of time). The action plan that comprises various support measures and the necessary resources was developed using the empirical results of this study as well as the existing findings and best practices found in the literature study. It was scrutinized and approved by a number of experts. The researcher recommends that the plan should be implemented over the next five years at AAU in order to improve the support provided to students with VI. / Inclusive Education / D. Ed.

Understanding climate change and variability at urban scale is essential for water resource management, land use planning, and development of adaption plans. However, there are serious challenges to meet these goals due to unavailability of observed and / or simulated high resolution spatial and temporal climate data. Recent efforts made possible the availability of high resolution climate data from non-hydrostatic regional climate model (RCM) and statistically downscaled General Circulation Models (GCMs). This study investigates trends in climate and urbanization and their impact on surface water supply for the city of Addis Ababa, Ethiopia. The methodology presented in this study focused on the observed and projected NIMRHadGEM2- AO model and Special Report on Emissions Scenarios (SRES) of B2 and A2 of HadCM3 model are also employed for rainfall, maximum temperature and minimum temperature data using for climate analysis. Water Evaluation and Planning (WEAP) modeling system was used for determination of climate and urbanization impacts on water. Land-Sat images were analyzed using Normalized Differencing Vegetation Index (NDVI). Statistical downscaling model (SDSM) was employed to investigate the major changes and intensity of the urban heat island (UHI). The result indicates monthly rainfall anomalies with respect to the baseline mean showing wet anomaly in summer (kiremt) during 2030s and 2050s, and a dry anomaly in the 2080s under A2 and B2 scenarios with exception of a wet anomaly in September over the city. The maximum temperature anomalies under Representative Concentration Pathways (RCPs) also show warming during near, mid and end terms. The mean monthly minimum temperature anomalies under A2 and B2 scenarios are warm but the anomalies are much lower than RCPs. The climate under the RCP 8.5 and high population growth (3.3 %) scenario will lead to the unmet demand of 462.77 million m3 by 2039. Future projection of urban heat island under emission pathway of A2 and B2 scenario shows that, the nocturnal UHI will be intense in winter or dry season episodes in the city. Under A2 scenario the highest urban warming will occur during October to December (2.5 ºC to 3.2 ºC). Under RCP 8.5 scenario the highest urban warming will occur during October to December (0.5 ºC to 1.0 °C) in the 2050s and 2080s. Future management and adaptation strategies are to expand water supply to meet future demand and to implement demand side water management systems of the city and UHI / College of Agriculture and Environmental Sciences / Ph.

The purpose of the study was to identify and transform, as necessary, constructs of communication satisfaction and to develop a hybrid quantitative audit of organisational communication satisfaction for collectivist contexts that is both reliable and valid, using Amos Graphics for structural equation modelling. The objective was also to develop a full latent variable model and to test its fitness to the data collected from a random sample of civil servants across Addis Ababa’s civil service bureaus. The study comprised three sequential parts, namely pilot, exploratory factor analysis (EFA) (Main Study One) and confirmatory factor analysis (CFA) (Main Study Two). These were used as per the existing framework in instrument development and validation. The pilot study indicated the need for more robust data. After a series of tests, principal factor axis factoring with oblique rotation was used as the most appropriate for perceptual data, out of several options on the EFA menu. The initially hypothesised six-factor solution with the dimensions of horizontal communication, personal feedback, supervisory communication, communication climate, relational trust and job satisfaction was found to be unfit for the data on conceptual and statistical grounds and psychometric analyses which involved the use of eigenvalues and the scree plot. A more appropriate two-factor solution based on the more precise parallel analysis strategy was consistent with current research that communication satisfaction is best conceptualised in terms of informational and relational domains as operationalised using the EFA procedure. The two-factor solution led to the formation of a 17-item scale out of the original 30-item measure, with two latent dimensions namely relational satisfaction and informational satisfaction. The items of the new EFA-generated organisational communication satisfaction scale were renumbered consecutively and the scale was cross-validated on a xiv new sample of 288 civil servants from the Addis Ababa City Administration. The cross-validation necessitated model respecification and re-estimation. The respecified model underwent validation at different levels. All seven aspects of validity, namely content validity, construct validity, factorial validity, reliability, convergent validity, discriminant validity and nomological validity, were addressed and found to be adequate. However limitations are also indicated as avenues for further enquiry. / Communication Science / D. Litt. et Phil. (Communication)

Text in English with abstracts and keywords in English and Setswana / Aim: The purpose of the research was to determine the magnitude and factors associated with gestational diabetes mellitus (GDM), and to explore the experiences of gynaecologists/obstetricians and midwives in the monitoring and prevention of GDM- related adverse maternal outcomes in order to propose best practice guidelines which may be implemented to overcome the problem. Methods: A concurrent mixed methods design was used. Participants for the quantitative study were selected using systematic random sampling, with purposive sampling being used for the qualitative part of the study. A total of 2000 medical records were reviewed using a checklist, in addition to which 7 gynaecologists/obstetricians and 12 midwives were interviewed using an in-depth interview guide. Descriptive and inferential statistics were used for the quantitative part, while Colaizzi’s manual qualitative data analysis method wasused for the qualitative part of the study. Findings: The magnitude of GDM was found to be 2.2%. Age and family history of diabetes mellitus were found to be factors associated with GDM (at p < 0.001). Other factors such as obesity, previous GDM, previous history of fetal macrosomia and multiple gestations were identified by respondents as factors related with GDM. In addition, the study explored the experiences of health professionals (HPs) in the monitoring and prevention of adverse maternal outcomes related to GDM, with the results showing some differences in screening and diagnostic techniques. It was also shown that lifestyle modification (physical exercise, diet management) and medication were utilised for managing women with GDM. In this regard, all the HPs agreed that creating awareness is the best intervention for preventing GDM as well as its adverse maternal outcomes. Conclusions: The magnitude of GDM is increasing, and much needs to be done to draw attention to the burden that GDM places on the health of pregnant women and the public. Since GDM is not considered a public health problem, little is being done to monitor the condition and its adverse maternal outcomes. It is hoped that the best practice guidelines developed from this research study may assist in reducing the adverse maternal outcomes of GDM in Ethiopia / Maikaelelo: Lebaka la patlisiso e ne e le go tlhotlhomisa go nna teng le mabaka a a golaganeng le bolwetsi jwa sukiri jwa baimana (GDM), le go tlhotlhomisa maitemogelo a dingaka tsa malwetsi a basadi (gynaeologists/ obstetricians) le babelegisi mo go tlhokomeleng le go thibeleng ditlamorago tse di maswe mo baimaneng tse di amanang le GDM gore go tshitshinngwe dintlhakaelo tse di gaisang tse di ka diragadiwang go fenya bothata.

Much research has been done on the job satisfaction of secondary school teachers in Addis Ababa, Ethiopia. The aim of this research was to investigate factors that influence the job satisfaction of these teachers. A literature review of theories on job satisfaction was undertaken. In the empirical investigation, a mixed-methods sequential explanatory design was used. In the quantitative phase, the data collection was done by means of a self-constructed structured questionnaire that focused on four work factors that were identified during the literature review, namely salary and benefits, management, work characteristics, and interpersonal relationships. The stratified, random sample consisted of 300 secondary school teachers in Addis Ababa. The data were statistically analysed using the Statistical package for the Social Sciences (SPSS) computer software programme, and the results were appropriately interpreted. In the second, namely the qualitative phase, interviews were conducted with a sample of 10 teachers who were purposefully selected from a larger sample. The data were analysed by using the constant comparative method. The results make a significant contribution to new knowledge and understanding of current issues relating to the job satisfaction of teachers in selected secondary schools in Addis Ababa. The results indicated that the teachers were significantly dissatisfied with most aspects of their work. Salary and benefits emerged as the primary dissatisfying aspect of all the work factors. Other areas of dissatisfaction related to poor fringe benefits and opportunities for promotion, the management style of the principals, the lack of decision-making opportunities for the teachers, as well as the opportunity to develop personally, and the poor relationships teachers have with the principals and the parents. The data also indicated that teachers who were 50 years and older, were significantly more satisfied with their work than the younger teachers. Accordingly, teachers with 21 years and more experience were also significantly more satisfied with their work than the less experienced teachers. In addition, all four of the identified factors were found to have statistically significant correlations with job satisfaction. Qualitative data confirmed the quantitative results. Finally, recommendations were made in order to enhance the job satisfaction of secondary school teachers in Addis Ababa, and for further research. / Psychology of Education / D. Ed.

Cette thèse questionne les liens entre les territoires urbains et la valorisation non institutionnelle des déchets dans deux capitales africaines, Dakar au Sénégal et Addis Abäba en Éthiopie. Ces relations sont interrogées à l’aune du contexte actuel de modernisation de ces agglomérations, qui ont fait du « vert » et surtout du « propre », de nouveaux paradigmes de leur développement. Tandis que la plupart des études portent sur les carences ou les défaillances de la gestion officielle des services urbains, cette recherche se focalise sur la valorisation des déchets, qui considère ces derniers comme une ressource. Celle-ci, de plus en plus mise en avant au Nord, est une forme de traitement qui redonne de la valeur aux ordures. Au Sud, et dans les deux capitales étudiées, elle est aux mains du secteur informel et des ménages. Dans ce cadre, cette thèse a pour ambition de comprendre, à travers leur valorisation non institutionnelle, comment les déchets participent à la construction de territoires et influent sur les évolutions urbaines actuelles à Dakar et Addis Abäba. La dimension spatiale du processus est étudiée à travers l’analyse et la mise en relation de ce que nous appelons les « lieux de l’ordure » (décharges, marchés des déchets, etc.) perçus comme marginaux. La comparaison et les enquêtes de terrains qualitatives (questionnaires et entretiens) donnent à voir les modalités du développement de la valorisation, ses spécificités et les dynamiques territoriales qu’elle produit. Cette thèse montre que ces dernières peinent à s’insérer dans les nouvelles donnes urbaines, voire interfèrent négativement avec les tentatives de régulation en cours. En revisitant la thématique de l’informel, ce travail questionne les possibilités de développement pour ‐ et les risques encourus par ‐ un processus fondamental pour faire des déchets une ressource urbaine en Afrique. / This thesis examines the links between urban areas and non-institutional recycling in two African capitals : Dakar, Senegal and Addis Ababa, Ethiopia. These connections are studied regarding the current state of modernisation of these metropolises, which have been going green and above all keeping it clean and became models of development. Most of the studies are about the lacks and the flaws of the bureaucratic management of the urban transit. This research focuses on recycling, which they see as resource. The latter, more and more promoted in the North, is a way of handling the rubbish that puts more value into it. As for the South and in those two capitals in particular, recycling is the hands of the informal sector and households. In this case, this thesis aims to understand through informal recycling how rubbish plays a part in the creation of territories and the current expansions of Dakar and Addis Ababa. The spatial dimension of the procedure is studied through the analysis and the links of what we call “rubbish spots” (rubbish tips, the waste market) are considered marginal. The comparison and qualitative field surveys (questionnaires and interviews) sho how recycling is developed, its specific features and the regional dynamism coming out of it. This thesis shows that the latter can barely be part of the new urban deal and that they have negative interference with the current regulations attempt. By revisiting the platform of the informal, this job questions the possible developments for – and the risks taken – for a fundamental process to trun rubbish into an urban resource on the African continent.

In a country like Ethiopia, where information and communication systems are in the early stage of development, software projects may face several challenges. Projects may suffer from schedule or budget overrun or unmet specifications, leading to failure. Risk is one of the factors that challenges project performance, and even causes failure. Hence, risk management helps project managers to control the effect of risks. However, risk management appears to be the least practiced component of project management. This study aims at assessing the risk management practice in the Ethiopian software projects. This study was undertaken using a survey conducted on 45 banks, insurance companies and UN agency offices in Addis Ababa, Ethiopia. The findings of the study suggest that formal risk management is not widely practiced in Ethiopian software projects. Only 16% of organisations reported that they applied one or more documented formal risk management techniques. Overall, 67% of organisations were found to exercise one or more risk management process steps. Though the risk management practice was found to be reasonably high, the proportion of organisations that carry out all the risk management process phases, through formal or informal methods, was only 27%, showing that risk management practice in Ethiopia cannot be considered adequate. The study thus recommends that Ethiopian software project managers should give more emphasis for risk management in their project management. The risk items that Ethiopian software projects face most were found to be technical complexity risks, with the highest risk item being use of new technology. This may be an indication that project managers should give adequate attention to the risks arising from technical complexity. No statistically significant relationship was observed between formal risk management and project success, and also between risk management practice and project success. / College of Engineering, Science and Technology / M.Sc.

One of the most significant urban transport problems is traffic congestion. All major cities both in developed and developing countries are facing the problem due to increasing travel demand caused by increasing urbanization and the attendant economic and population growth. Recognizing the growing burden of traffic congestion, community leaders and transportation planners in Addis Ababa are still actively promoting large-scale road constructions to alleviate traffic congestion. Although Intelligent Transportation Systems(ITS) applications seem to have the potential to improve signalization performance, highly congested intersections in Addis Ababa are still controlled by a timed signal and manual operation. Moreover, these pre-timed signal controls are functioning sub-optimally as they are not being regularly monitored and updated to cope with varying traffic demands. Even though the benefits are well known theoretically, at the time of writing of this thesis, Adaptive Traffic Signal Controllers (ATSC) haven’t been deployed in Ethiopia and no research has been conducted to demonstrate and quantify their effectiveness. This master’s research thesis, therefore, intends to fill the identified gap, by undertaking a microscopic traffic simulation investigation, to evaluate the benefits of adopting a Traffic-responsive Urban Control (TUC) strategy and optimizing traffic signal timings. For the purpose of this study, an oversaturated three-intersection test corridor located in the heart of Addis Ababa city is modeled in VISSIM using real-world traffic data. After validating the calibrated model, the corridor was evaluated with the existing pre-timed, TRANSYT optimized pre-timed plan and TUC strategy. Multiple simulation runs were then made for each scenario alternatives and various measures of effectiveness were considered in the evaluation process. Simulation evaluation has demonstrated an average delay reduction of 24.17% when the existing pre-timed alternative is compared to TRANSYT optimized plan and 35% when compared to the TUC strategy. Overall evaluation results indicate that deploying the TUC strategy and optimizing the aging pre-timed signal plans exhibits a significant flow improvement. It is expected that the result of the thesis work will be an input for future comprehensive policy development processes.

This study attempted to identify personal (patient-related) factors influencing anti-retroviral therapy (ART) adherence in Addis Ababa, Ethiopia. A quantitative, descriptive, cross-sectional and analytical design was used. Structured interviews were conducted with 355 ART patients. The findings revealed that stigma, discrimination, depression and alcohol use negatively affected patients’ ART adherence levels. However, patients’ knowledge levels had no influence on their ART adherence levels, contrary to other researchers’ reports. Addressing stigma and discrimination at community levels might enhance patients’ abilities to take their medications in the presence of others. Healthcare professionals should be enabled to diagnose and treat depression among ART patients during the early stages. Non-adherent ART patients should be counseled about possible alcohol abuse. / Health Studies / M.A. (Public Health with specialisation in Medical Informatics)
