(Kenyatta University, 2024-06-14) Olumu, Japheth Akello; Ngéno, Weldon K.
The research aimed to explore the association
between occupational stress and job
performance. The research objectives were; to
explore the relationship between
organizational demands and job performance,
to examine the effects of management style on
job and to establish the extent to which
workload affect job performance of NGAO
officers in Tharaka-Nithi County. The Person Environment Fit theory (P.E. FIT), Demand Control theory, and Herzberg's Two-Factor
theory anchored the study. In order to explore
the association between occupational stress
and NGAO job performance in Tharaka-Nithi
County, Kenya, the research utilized both
descriptive and exploratory research design.
The study's target population consisted of 83
individuals who were selected from various
NGAO officers in Tharaka-Nithi County.
These individuals included chiefs, deputy
county commissioners, assistant county
commissioners, and county commissioners.
Through convenience and random sampling,
68 respondents in total were found. In order to
provide both qualitative and quantitative data,
the questionnaires that were utilized to gather
primary data will include both structured and
open-ended questions. The respondents were
given the questionnaires, and they had
fourteen days to complete them before the
answers were gathered. Participants were
asked to take part and indicate their readiness
to contribute to the questionnaire items.
Regression analysis was utilized to do
inferential statistics while the mean and
standard deviation were employed to code and
analyze the gathered data. The data was
represented using percentages, and frequency
tables. The outcomes uncovered that the
research factors had a substantial impact on
the job performance of National Government
Administrative Officers, as evidenced by the
coefficient of correlation of 0.879. The
modified determination coefficient came out
to be 0.746, or 74.6%. This demonstrates how
changes in the independent variables;
workload, management style, and
organizational demands explained differences
in the dependent variables. The findings also
revealed that P-value was 0.003<0.05
indicating that job performance among
National Government Administrative Officers
was significantly influence by the study
variables. The study concludes that
organizational demands, management style
and workload positive significant impacted
the job performance among National
Government Administrative Officers. The
study recommends that government agencies
should conduct comprehensive assessments of
organizational demands to identify areas of
inefficiency and opportunities for
improvement. This entails reviewing
processes, procedures, and workload
distribution to ensure alignment with
organizational goals while minimizing
unnecessary burden on NGAO officers.
Implementing streamlined workflows,
prioritizing tasks, and allocating resources
effectively can help mitigate workload
pressures and enhance job performance

Thermal Applications of Carbon Nanotubes in Polyethylene Glycol in the Presence of Magnetic Field on Electronic Devices
(IOSR Journal of Mathematics (IOSR-JM), 2025-04) Muteti, Winfred; Chepkwony, Isaac
Background: In this study, the thermal management of electronic devices, specifically CPUs, using carbon nanotubes (CNT) dispersed in polyethylene glycol (PEG-400) under the influence of a magnetic field was studied. The research aims to optimize cooling performance by enhancing efficiency, extending the operating temperature range, and improving the reliability of such systems. Materials and Methods: The study modeled impingement cooling using a Darcy-Brinkman-Forchheimer approach and considered the effects of viscous dissipation. The governing nonlinear partial differential equations were converted into nonlinear ordinary differential equations (ODEs) by utilizing similarity variables and solved using numerical methods. CNT-PEG-400 nanofluid flowing via a porous metal foam CPU cooler with a fan and a heated CPU surface was simulated. Results: The investigation of key parameters like Hartmann number, Reynolds number, Darcy number, and porosity revealed that increasing the Darcy number significantly enhances heat transfer. The Hartmann number’s effect varies with porosity, where stronger magnetic fields are advantageous for highly porous metal foams, ultimately improving cooling efficiency. Conclusion: CNTs increase both the density and viscosity of PEG-400, leading to enhanced heat transfer characteristics, which improve overall cooling performance. These findings contribute to optimizing cooling strategies for CPUs and other electronic devices, especially when using CNT-PEG-400 nanofluids in the presence of magnetic fields.
Entrepreneurial orientation, learning orientation, cost focus and innovation in agri-food SME of Uganda
(African Journal of Rural Development, 2022-04) Ajer, B.; Ngare, L.; Macharia, I.
Agri-food Small and Medium Enterprises (SMEs) play a key role in the economies of most developing countries. With increasing challenges and competitiveness, innovation has been shown to play a critical role in sustaining growth of the numerous agri-food SMEs in developing countries. This innovation is influenced by several factors including entrepreneurial orientation (EO) of the firm. This study introduces learning orientation and cost focus into the EO-Innovation paradigm with the aim of understanding the relationship among EO, learning orientation, cost focus and innovation. The study was conducted in the districts of Kampala, Mukono, Wakiso and Jinja in Uganda. These districts collectively have the highest concentration of agri-food firms in the country. Primary cross-sectional data were collected using semi structured questionnaires from a cross-section of 521 SMEs spread across the study area. Data were analyzed using multivariate structural equation modeling in AMOS v.23. Results suggest the importance of proactiveness in enhancing learning orientation, cost focus and innovation. On the other hand, entrepreneurial proclivity was seen to have significant influence on learning orientation and cost focus but not on innovation. The findings of this study have implications in agri-food SME learning orientation and cost focus. In essence, helping SMEs to become proactive or have high levels of proclivity would also increase their cost focus and learning orientation which are all important for the sustainability of agri-food SMEs. Keywords: Agri-food, entrepreneurial proclivity, learning orientation, proactiveness, small and medium enterprise, Uganda
