This dissertation aims to investigate determinants and to map the research landscape in Africa. Methodologically, the dissertation employs a survey design comprising (i) three quantitative studies using survey data collected from Addis Ababa and analyzed through PLS-SEM, and (ii) two bibliometric reviews (2004–2024) using Bibliometrix and VOSviewer to assess Ethiopian and African EV research trends. The first empirical study surveyed 394 potential buyers using Extended Unified Theory of Acceptance and Use of Technology (UTAUT2) model; the second surveyed 347 respondents applying Theory of Planned Behaviour (TPB) and Technology Acceptance Model (TAM) to assess public attitudes; and the third analyzed 326 EV users basing Consumer Satisfaction Theory (CST) and Expectation Confirmation Theory (ECT,) and incorporating perceived value and government incentives as mediators and moderators respectively. Findings show that performance expectancy and social influence significantly shape adoption intention, while effort expectancy is insignificant and price value has a modest effect. Meanwhile, public attitudes are strongly driven by performance and social influence. Moreover, user satisfaction is enhanced by charging infrastructure; price negatively influenced users‘ satisfaction, and perceived value ha as full mediated role on performance. Government incentives moderated the relationship. The Bibliometric analysis shows a rapid global rise in EV research but limited researches in Ethiopia and Africa. The study strengthens the theoretical foundations of UTAUT2, TAM, TPB, CST, and ECT in emerging-economy contexts while providing practical, actionable insights for policymakers on infrastructure development, incentive design, and awareness strategies. Future research should broaden coverage, apply mixed-methods and integrate emerging variables.

Mechanization enhances productivity and efficiency, reduces post-harvest losses, enables deeper ploughing, and allows for more precise input application. It also reduces labor intensity, making it possible for households to reallocate labor toward education and non-farm activities, thereby improving overall household welfare. Nevertheless, mechanization may negatively affect farm diversification and nutritional security, issues often underrepresented in policy discourse. In response to these complexities, this study was initiated to investigate the determinants and impacts of mechanization on production efficiency, multidimensional rural poverty, and food and nutrition security in Ethiopia’s Arsi Zone. To achieve this, data were gathered from 413 randomly selected households between June and August 2023. Primary data were collected through household surveys, focus group discussions, and key informant interviews, while secondary data were sourced from relevant institutions. The analysis employed a range of quantitative models, including multivariate probit, Tobit, ESR, CESR, ESRpo, IV fractional probit, PSM, and MESR, to ensure robust and comprehensive insights. Descriptive analysis revealed that 59% of households use combine harvesters, 51% use tractors, and 40% adopt both, with labor shortages and productivity gains cited as primary drivers. According to the multivariate probit and Tobit models, education, access to credit, and cooperative membership significantly increased both adoption and intensity of mechanization, whereas land fragmentation and crop diversification negatively influenced uptake. The MESR model demonstrated that mechanization, whether adopted individually or jointly, substantially improved wheat technical efficiency, boosted productivity, and reduced poverty. Moreover, ESR results indicated a 70% increase in the likelihood of higher income for adopters, while CESR and ESRpo models revealed a 43% increase in food security likelihood and a 23.86% reduction in HFIAS scores, thereby affirming mechanization’s role in supporting Sustainable Development Goals such as “No Poverty” and “Zero Hunger.” However, results from the IV fractional probit and PSM models showed that mechanization significantly reduced agricultural diversification among mechanized farmers, as indicated by PSM result declines in the Agricultural Diversification Index (−0.0993), Crop Diversification Index (−0.119), and Livestock Diversification Index (−0.0789), which has important implications for dietary diversity. Based on Multitreatment Endogenous Switching Regression, diversification in the absence of mechanization improved dietary diversity (HDDS) by 0.761 units (t = 4.15) and food consumption scores (FCS) by 5.60 units (t = 12.60), while diversification in mechanized households increased HDDS by 0.65 units and FCS by 1.41 units, both significant and positive. However, mechanization improved food access for non-diversified households (FCS + 1.15, t = 2.224) but reduced dietary diversity (HDDS − 0.609, t = −5.985) and food consumption scores (FCS − 1.24, t = −4.16) among diversified households, indicating a potential trade-off between mechanization and nutrition. Based on these findings, the study concludes that mechanization adoption is a multifaceted process shaped by household assets and technology attributes. While mechanization improved rural households’ welfare, its interaction with diversification and nutrition warrants careful policy consideration. Mechanization policies should be accompanied by complementary measures that expand credit access, strengthen cooperatives, and improve extension services, while addressing potential adverse effects on diversification and nutrition.

The research adopted a positivist paradigm, employing a quantitative and discriptive-explanatory approach. Data collection involved a standardized, self-administered questionnaire distributed to 381 selected brewery employees through simple random sampling. Statistical methods were utilized via SmartPLS, SEM, and SPSS version 27 to test hypotheses regarding the relationships between the study variables. The findings revealed a positive and significant relationship between employees' dynamic capability and performance. This held even when dynamic capability scores were relatively low, suggesting a consistently positive influence. Additionally, a positive and significant relationship was found between employee dynamic capability (independent variable) and entrepreneurial orientation (mediating variable). Furthermore, entrepreneurial orientation demonstrated a positive and significant relationship with employee performance. While the direct effect analysis indicated a positive relationship between employees’ dynamic capability and performance, the inclusion of entrepreneurial orientation as a mediator strengthened this association. The data analysis and presentation revealed that considering entrepreneurial orientation as a mediator increased the explained variance in employee performance, confirming partial mediation. Based on these findings, the dissertation offers practical recommendations for Brewery factories of Addis Ababa, managers, employees, and future researchers. Recommendations for Factories include fostering a culture that encourages employee learning and innovation to enhance dynamic capabilities. Managers are advised to develop programs that promote proactive problem-solving and opportunity identification among employees. Employees are encouraged to embrace continuous learning and actively seek opportunities to contribute their ideas.

These days, many organizations have been turning to the implementation of knowledge management. This is because the use of knowledge inside an organization is enhancing its performance. This study has been conducted to examine the effect of knowledge management on organizational performance and the mediation role of organizational learning in the Amhara Region Agricultural Research Institute. The study employed a descriptive and explanatory research design with a mixed research approach. For the quantitative method, data were collected from a survey of 216 experts and analyzed using the structural equation model (SEM). Using Amos 23.0 software, the reliability and validity of the study were tested utilizing confirmatory factor analysis. Moreover, confirmatory factor analysis was utilized to test the measurement model, and structural equation modeling was employed to measure the conceptualized hypotheses. The direct and indirect effects of knowledge management on organizational performance were rigorously tested through a quantitative approach, and the variables under the study were articulated employing the qualitative approach so as to obtain more conprehensive findings. The descriptive result revealed that knowledge acquisition, knowledge creation, and knowledge implementation had modest mean values, while knowledge transfer and storage were the lowest. With respect to the correlation value of the variables, the finding revealed that there was a strong correlation between knowledge management, organizational learning, and organizational performance. In addition, the major quantitative results demonstrated that knowledge management has a direct, significant effect that improves the Amhara Region Agricultural Research Institute in part through organizational learning, and organizational learning has also a significant direct effect on organizational performance. In aspect of the mediation effect, organizational learning has also a positively significant partial complementary mediation role in the relationship between knowledge management and organizational performance. Lastly, the qualitative research findings obtained from the interview demonstrated that the knowledge management themes, typically knowledge acquisition and knowledge creation, had been practically implemented in the institution, whereas the institution has limited practice in knowledge transfer, knowledge storage, and knowledge application. From the organizational learning theme, the result revealed that managers were committed to employing different agricultural technologies, and the system was clearly designed. In view of organizational performance, the qualitative result also revealed that the institute did a lot only on human development and research and development endeavors. Therefore, the qualitative findings had partially supported the quantitative study findings. The study has contributed additional empirical evidence of the importance of improving organizational performance through executing valuable knowledge. Thus, it is suggested that the Amhara Region Agricultural Research Institute would do better to adopt sophisticated knowledge management dimensions and broaden competency-based management, and future research would also look into other likely mediating and moderating factors such as engagement, innovation, and commitment.
