Adoption Rates and Yield Enhancements in Kenyan Dryland Villages via Climate-Resilient Seeds
type: item
description: This study examines the adoption rates of climate-resilient seeds in Kenyan dryland villages to enhance agricultural yields and resilience against climate variability. A mixed-methods approach combining quantitative surveys with qualitative interviews was employed. Farmers were surveyed using structured questionnaires to gather data on their experiences with climate-resilient seeds, while in-depth interviews explored deeper insights into their motivations and challenges. Data analysis utilised descriptive statistics for yield measurements, thematic analysis for qualitative data, and regression models to identify predictors of adoption. The survey results indicated that approximately 60% of farmers adopted climate-resilient seeds, with higher adoption rates among those who perceived greater benefits in terms of drought tolerance (r = -0.53; p < 0.01). Findings suggest that farmer perceptions significantly influence the uptake of climate-resilient seeds, highlighting the need for targeted educational initiatives to improve seed acceptance. Recommendations include developing tailored agricultural extension programmes focused on improving drought tolerance education and providing financial incentives for seed adoption in dryland areas. climate-resilient seeds, sustainable agriculture, yield enhancement, farmer perceptions, mixed-methods approach

Methodological Evaluation of Secondary Schools Systems in Kenya Using Bayesian Hierarchical Models for Adoption Rate Measurement
type: item
description: Secondary schools in Kenya are a significant part of the education system, with varying degrees of adoption of modern educational practices. The review synthesizes existing studies on secondary schools adoption rates, employing Bayesian hierarchical models as a novel approach to measure these rates with improved precision and robustness. A key finding is the significant variation (32-45%) in reported adoption rates across different regions and educational initiatives, highlighting the need for more localized data collection methods. The proposed Bayesian hierarchical model offers a methodological advancement by accounting for both within-school and school variability, enhancing the accuracy of adoption rate measurements. Educational policymakers should consider implementing this novel model to improve the reliability and comparability of assessment results across different contexts in Kenya's secondary school systems. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

In particular, these variations can affect navigation and communication technologies that rely on magnetic field data. The methodology involves a systematic review of published literature, including observational data from magnetometers and satellite observations. A quantitative analysis will be conducted using statistical models to evaluate the impact of geomagnetic variations on local technologies. Recent studies have identified significant fluctuations in the geomagnetic field direction over Benin, with changes exceeding ±0.5° in some regions during solar activity cycles. The review underscores the importance of understanding geomagnetic variability for ensuring reliable technological operations in remote areas of Africa. Future research should focus on developing more robust models to predict and mitigate geomagnetic-induced disruptions. Investigate the development of adaptive technologies that can automatically adjust to geomagnetic changes, thereby maintaining the accuracy of navigation systems and communication devices. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Renewable Energy Microgrids in Ethiopian Rural Communities
type: item
description: Renewable energy microgrids are increasingly being deployed in rural communities to address power reliability issues and stimulate economic development. A mixed-method approach combining surveys with case studies was employed to gather data from targeted rural communities. Statistical models were used to assess the effectiveness of microgrid systems in terms of energy supply stability and socio-economic benefits. Microgrids demonstrated a significant improvement (p<0.05) in power reliability, leading to a 20% increase in productive activities and an average annual growth rate of 8% in local businesses within the communities studied. The integration of renewable energy microgrids has had substantial positive effects on both economic activity and community well-being in Ethiopian rural areas. Further deployment should prioritise inclusive planning processes that involve local stakeholders, ensuring equitable access to benefits from renewable energy investments.

Methodological Assessment of Manufacturing Plant Systems in Ethiopia Using Bayesian Hierarchical Models for Reliability Measurement
type: item
description: Manufacturing plants in Ethiopia face significant challenges related to system reliability, which can impact productivity and economic growth. A systematic literature review approach was employed to identify relevant studies and apply Bayesian hierarchical models to analyse data from these sources. The study aimed to evaluate the effectiveness of existing methodologies and propose improvements. Bayesian hierarchical models demonstrated improved accuracy in predicting system failures compared to traditional methods, with a predictive accuracy rate exceeding 90% for critical components. The use of Bayesian hierarchical models provided significant insights into enhancing reliability measurement in Ethiopian manufacturing plants. Manufacturing plant managers should adopt these models as part of their quality assurance processes. Policymakers can also leverage this methodology to improve the design and operation of future infrastructure projects.

Time-Series Forecasting Model for Evaluating Secondary School Systems Adoption Rates in Ethiopia
type: item
description: Secondary school systems in Ethiopia have been under significant scrutiny for their adoption rates over time, with limited empirical studies providing a comprehensive analysis. A time-series forecasting model, specifically an autoregressive integrated moving average (ARIMA) model, will be employed to forecast adoption rates based on historical data from the Ethiopian Ministry of Education. This theoretical framework establishes a robust methodological approach to evaluating secondary school systems in Ethiopia using time-series forecasting models, providing insights into educational system dynamics and potential policy implications. The findings from this study should inform policymakers on the most effective strategies for improving adoption rates of secondary education systems in Ethiopia. Future research could focus on validating these predictions with actual data over a longer period. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
