Importance of nested models in modeling infectious diseases.

Mbabazi, Fulgensia Kamugisha; Kimathi, Mark (Strathmore University, 2017-07)

Mathematical models are believed to achieve good results in the prediction of disease prevalence. The progression of an infection within a host determines the capacity of a pathogen to spread to new hosts and to sustain ...
Modeling the within-host co-infection of influenza A virus and Pneumococcus

Mbabazi, Fulgensia Kamugisha; Mugisha, J.Y.T; Kimathi, M. (Elsevier In. - Science Direct, 2018)

In this paper a nonlinear mathematical model for a within-host co-infection of influenza A virus and pneumococcus is investigated. Conditions that explain the relations amid RIP and its relationship to the global asymptotic ...

Incorporating assessment of learning in assessment for learning :

Atibuni, Dennis Zami; Olema, David Kani (AEAA, 2018)

All efforts invested in teaching are futile without ascertaining that learning has taken place. The only proof that learning has taken place is an assessment result or outcome. In considering this single most important ...

Epistemological dynamics and incorporation of appraisal practices in Kampala archdiocesan secondary schools.

Muweesi, Charles (Scientific Journal of Education, 2018-12)

Using selected secondary schools in Kampala Archdiocese, the study was intended to establish the appraisal practices used to assess teachers’ performance in secondary schools in Kampala Archdiocese, Census and simple random ...
Quantification and characterization of cocoa pod husks for electricity generation in Uganda.

Kilama, George; Lating, Peter O.; Byaruhanga, Joseph; Biira, Saphina (Busitema University ; BMC, 2019)

Background: Due to limited coverage, the electricity power supply in Uganda is an obstacle to the country’s economic development. Utility firms in Uganda either lack the financial capacity to expand their grids to isolated ...
Trends and Status of Women in Physics in Uganda.

D’ujanga, Florence M.; Biira, Saphina; Akoba, Rashida (Busitema University ; AIP publishing, 2019)

Most women in Uganda with an advanced degree in physics find employment at a university, teaching and conducting research. Very few take jobs in by industry or at government research laboratories. This paper discusses the ...
Enhancing work-life balance and research engagement among students in higher education institutions.

Atibuni, Dennis Zami; Olema, David Kani; Ssenyonga, Joseph; Kibanja, Grace Milly (Busitema University., 2019)

Engagement in higher degree pursuit is a function of psychological constructs including core self-evaluations, academic motivation, work-life balance, and research skills proficiency. Core self-evaluations and academic ...
Education Headteachers’ Management Styles and Teachers’ Role Performance in Secondary Schools in Tororo District, Uganda.

Oketcho, Emmanuel James; Ssempala, Fredrick; Ujeyo, Margaret Stella Suubi; Atibuni, Dennis Zami (SAGE, 2019)

This mixed-methods study stems from the poor learner performance in secondary schools in Tororo District, Uganda, which connoted low teacher role performance and gaps in head teachers’ management styles. Management styles ...
Research as Assessment for Learning vs Assessment of Learning at Higher Education.

Atibuni, Dennis Zami (Busitema University., 2019)

At higher education, students are terminally assessed through a research output that demonstrates their originality, creativity, innovativeness, and contribution to knowledge and problem solving in society. However, the ...
Shifting from assessment of learning to assessment for learning in postgraduate research.

Atibuni, Dennis Zami (Busitema University, 2019)

Postgraduate students are terminally assessed through research. Depending on whether the students undertake research as an assessment by mastery orientation or performance orientation will determine whether the process ...
