Behavioral Analysis Using Machine Learning Algorithms in Online Proctored Assessments; The Potential of Mobile Proctoring in E Assessments: A Review
(COMPILER, 2026-10) Oganda Bartholomew Mogoi1; John Kamau; Raymond Ongus
The rapid expansion of online learning has intensified the need for secure and reliable examination systems. While artificial intelligence (AI) and machine learning (ML) are increasingly employed to safeguard integrity through behavioral analysis, current proctoring solutions remain largely desktop-centric and poorly adapted to mobile environments, where smartphones dominate access. These limitations—spanning heterogeneous hardware, unstable lighting and connectivity, algorithmic bias, privacy concerns, and limited explainability—undermine fairness and trust in misconduct detection. This study reviews the potential of mobile-based proctoring systems that leverage ML for real-time behavioral analysis in e-assessments. A systematic search across Scopus, IEEE Xplore, SpringerLink, and Google Scholar identified 200 publications from 2015–2025. After applying inclusion and exclusion criteria, 30 peer-reviewed empirical studies were analyzed in depth. Findings reveal that ML-driven behavioral analytics enhance accuracy and fairness by detecting anomalies such as gaze aversion, facial emotion changes, and environmental inconsistencies. However, research gaps persist in mobile optimization, ethical safeguards, privacy protection, and bias mitigation. The review concludes that hybrid mobile frameworks integrating multimodal behavioral features and adaptive ML models are essential to strengthen proctoring accuracy while ensuring accessibility and privacy. Future research should prioritize context aware and explainable AI to foster equitable and trustworthy online assessment environments.

(Mount Kenya University, 2023-05-09) Sikini,Mary Bosibori; Kimani,Cecilia; Kamau, Joyce
The purpose of this study was to investigate the influence of physical facilities on the inclusion of learners with physical disabilities in Kisii Central Sub-County, Kenya. The research adopted the Social Model of Disabilities theory as its foundational framework. It employed a mixed-method approach and concentrated on 124 schools with 124 headteachers, 1949 teachers, and 92 learners with physical disabilities as its participants. The sample participants were selected by utilizing the Krejcie and Morgan (1970) table. The schools and learners with physical disabilities were selected through a simple random sampling technique, while teachers and headteachers were chosen through a stratified random sampling approach. Questionnaires and interview schedules served as the primary data collection tools, while a focus group discussion guide was utilized for engaging learners with physical disabilities. Additionally, an observation checklist was employed to assess school facilities. The piloting of instrument was conducted in a single school. The instrument's reliability was evaluated in the research study through a test-retest analysis. The researcher employed a blend of qualitative and quantitative methodologies for gathering data. The findings revealed mixed perceptions among participants regarding the effectiveness and implementation consistency of inclusive classroom practices such as accessible seating arrangements and adaptive outdoor equipment. The findings underscore the critical importance of physical facilities and in promoting inclusive educational environments. These findings suggest that investing in adequate infrastructure and providing accessible learning materials are pivotal in enhancing educational outcomes and inclusivity for students with diverse needs. Recommendations included fostering collaborative efforts among stakeholders to enhance the implementation and effectiveness of inclusive practices, thereby creating more supportive environments for learners with physical disabilities.

Strategic Leadership and Incident Response Time Among Law Enforcement Agencies in Juba City, South Sudan
(Mount Kenya University, 2026-01) Ekidor,Paul; Kiprono,Wilson; Wekesa,Peter
The purpose of this study was to investigate the dynamics of strategic leadership on incident response time among law enforcement agencies in Juba City, South Sudan. The contention of the article is that incident response time is widely recognized as a critical indicator of law enforcement effectiveness, particularly within fragile and post-conflict contexts where institutional capacity and public trust remain limited. In South Sudan, persistent insecurity and weak governance structures have heightened the demand for timely and effective law enforcement responses, especially in urban centers such as Juba City. This paper examines the influence of strategic leadership on incident response time among law enforcement agencies in Juba City, South Sudan. Anchored in strategic leadership theory and the organizational performance literature, the study posits that leadership practices including strategic planning, coordination, resource allocation, and decision-making play a decisive role in shaping operational responsiveness. Employing an exploratory qualitative approach informed by a review of relevant empirical studies and contextual evidence, the paper finds that deficiencies in strategic leadership contribute to delayed response times, fragmented operations, and ineffective interagency coordination. Conversely, effective strategic leadership is associated with improved preparedness, clearer command structures, and enhanced operational agility. The study concludes that leadership-centered reforms are essential for strengthening incident response capabilities, improving public safety, and rebuilding public trust in law enforcement institutions in South Sudan.

Strategic Leadership and Case Resolution Performance in Police Departments in Juba City, South Sudan
(Mount Kenya University, 2026-01) Ekidor, Paul
The purpose of this study was to investigate the association between strategic leadership and crime clearance performance, measured through the number of cases resolved per quarter, within police divisions in Juba City, South Sudan. The contention of the study is that crime clearance performance remains a central indicator of policing effectiveness, particularly in post conflict urban environments where institutional capacity, coordination, and leadership practices directly influence investigative outcomes. A mixed methods explanatory sequential design was adopted, integrating quantitative survey data from 235 law enforcement personnel with qualitative insights from key informant interviews. Structured questionnaires measured perceptions of leadership practices and investigative performance, while interviews provided contextual explanations of supervisory processes and operational challenges. Descriptive findings indicated moderately strong clearance performance, with a composite mean score of 3.81. Leadership contribution to case clearance recorded the highest mean of 4.05, suggesting that supervisory direction and oversight are perceived as central drivers of investigative productivity. Reliability analysis confirmed strong internal consistency of the measurement scale, with Cronbach alpha values exceeding 0.79. Pearson correlation analysis revealed statistically significant positive relationships between case resolution and all leadership dimensions, with inclusive leadership showing the strongest association (r = .659), followed by accountable leadership (r = .570), visionary leadership (r = .552), and adaptive leadership (r = .516). Multiple regression results demonstrated that leadership variables collectively explained 48.0 % of the variance in case resolution performance (R² = .480, F = 53.141, p < .001). Inclusive leadership emerged as the strongest independent predictor (β = .462, p < .001), while visionary leadership also showed a significant positive effect (β = .226, p = .001). The findings confirm that collaborative leadership practices and clear strategic direction substantially enhance investigative throughput and case completion within policing institutions operating under complex operational conditions. The study recommends strengthening participatory supervisory structures, improving communication of investigative targets, and institutionalizing routine performance monitoring systems to enhance crime clearance performance in Juba City.

Multimodal CNN–LSTM Framework for Real-Time Maize Disease Detection
(Mount Kenya University, 2026-06-03) Tonui,Mercy Chepkoech; Kamau , John; Ongus,Raymond Wafula
Maize diseases present a major challenge to agricultural productivity and food security, particularly in low-resource settings in sub-Saharan Africa. Timely detection plays an important role in reducing yield losses and enabling effective farm management. This research introduces and validates a multimodal machine learning–based system for real-time maize disease detection in Bomet County, Kenya. The system integrates maize leaf image data, environmental sensor data, and farmer-reported observations to develop a hybrid Convolutional Neural Network–Long Short-Term Memory (CNN–LSTM) model designed to automatically identify and categorize maize diseases. A mixed-methods research design was adopted, combining machine learning experiments with surveys and interviews involving farmers and agricultural officers. The findings revealed that Maize Lethal Necrosis (MLN) was the most prevalent disease (41%), followed by Gray Leaf Spot (33%) and Northern Leaf Blight (26%). Environmental variables such as humidity and temperature demonstrated strong associations with disease occurrence. The proposed multimodal CNN–LSTM framework integrates maize leaf images, environmental sensor data, and farmer observations, achieving an accuracy of 94.2%, which outperforms conventional image-only CNN models (87.5%) and environmental-data based LSTM models (81.3%). Additionally, 78% of farmers reported faster disease diagnosis using the developed system. The findings demonstrate that the proposed system supports real-time maize disease detection through an edge-enabled architecture, enabling deployment on mobile devices and facilitating practical intelligent system integration in agricultural environments.
