Working conditions and teacher commitment in government-aided secondary schools in Rubaga division, Kampala capital city authority, Uganda
(Kyambogo University (Unpublised work), 2025-11) Kyasiimire, Annet
This study examined the influence of working conditions on teacher commitment in government-aided secondary schools in Rubaga Division, under the Kampala Capital City Authority (KCCA). Specifically, it explored the impact of collegiality, the physical work environment, and workload on teacher commitment. Adopting a positivist approach, the study employed a cross-sectional research design and involved a sample of 177 teachers. Data were collected using a self-administered questionnaire and analyzed through descriptive statistics, correlation, and regression analyses. The findings indicated that collegiality, physical work environment, and workload each have a significant positive influence on teacher commitment. The study concluded that collegiality is essential for fostering teacher commitment; a safe, secure, and well-organized physical environment is critical; and workload, particularly in terms of teaching hours, contributes positively to commitment. Based on these findings, the study recommended that head teachers actively promote collegiality within schools. Furthermore, the Ministry of Education and Sports, along with head teachers, Boards of Governors, parents, and other stakeholders, should work collaboratively to improve the physical conditions of schools. Additionally, the Ministry and school leaders should ensure that teachers are provided with adequate non-instructional time to build meaningful relationships with students, thereby enhancing overall teacher commitment.
Investigating the dewaterability and resource recovery potential of distillery wastewater using sawdust and charcoal dust as conditioners
(Kyambogo University (Unpublised work), 2025-09) Angom, Hedina
Discharge of untreated distillery wastewater has a high impact on human and environmental health. One of the critical stages in its management is dewatering. However, understanding the dewatering characteristics of distillery wastewater is a grey area as minimal research has been done on it. This research evaluated the characteristics of distillery wastewater from various sources to identify any variations, its dewatering potential, enhancement of dewatering using conditioners and its resource recovery potential. The research was undertaken using laboratory measurements and experiments to determine the wastewater characteristics and dewaterability. Dewatering performance was measured in terms of capillary suction time (CST), and turbidity of supernatant after natural and mechanical settling. The findings of this study showed that distillery wastewater characteristics were very significant in pH (3.56-6.32) p=0.017, EC (4.22-34.77mS/cm) p=0.002, COD (63,800-148,680mg/L) p=0.004 and turbidity (18,700-45,500NTU) – p=0.167. Dewatering was noted to be CST (30-5512.64s) p=0.140 and turbidity of supernatant (14,700-87,500NTU) p=0.046. Enhancing dewatering using conditioners showed CST (60.56-9047.04s) p=0.452, 0.012, 0.207 and turbidity of supernatant (4.37-93,500NTU) p=0.002, 0.013, 0.788 with better performance observed after treatment with charcoal dust. Based on the Nitrogen (31-121mg/L), Phosphorus (195-757mg/L), Potassium (4580-13449.15mg/L) and TVS/TS ratio (0.76-0.91) values, distillery wastewater showed potential for resource recovery. Distillery wastewater needs to be treated to protect human and environmental health. Strict measures should be put in place to ensure adherence to standards for discharge into the environment.
Supplier selection and perceived contract performance in government ministries of uganda: a case of the ministry of health
(Kyambogo University (Unpublised work), 2024-11) Amumpeire, Annitah
This study examined the effect of supplier selection on contract performance in government ministries in Uganda, with a focus on the Ministry of Health. The study was guided by the Resource-Based View (RBV) and aimed to address three objectives: to determine the effect of supplier selection objectives on the contract performance of the Ministry of Health, to assess the effect of supplier identification on the contract performance of the Ministry of Health, to analyse the impact of selection evaluation criteria on the contract performance of the Ministry of Health. The study employed a case study design and included a sample of 103 staff members from the Ministry of Health. Data collection involved both quantitative and qualitative methods. Qualitative data were analysed using descriptive analysis and inferential statistics. Descriptive statistics described the response rate, respondent characteristics, and firm characteristics. Inferential statistics, including Pearson’s correlation, were used to examine the relationships between variables, while multiple regression analysis determined the effect of supplier selection on contract performance. The findings revealed that supplier evaluation criteria had the most significant impact on contract performance, followed by supplier selection objectives. Supplier identification, while still significant, had a relatively modest impact. The study concludes that a comprehensive approach to supplier management, integrating supplier selection with other procurement practices, is crucial for optimizing contract performance. The research offers valuable insights for government ministries and organizations seeking to enhance their supplier management practices and contract outcomes. The study's recommendations and suggested areas for further research aim to contribute to the development of more effective supplier management strategies in the public sector.
Not one size fits all: µ FTIR and pyrolysis GC MS for complementary analysis of microplastics in eutrophic surface water
(Analytical and Bioanalytical Chemistry, 2026-03-22) Omara, Timothy; Benetková, Barbora; Sumerskii, Ivan; Ssebugere, Patrick; Kyarimpa, Christine; Omwoma, Lugasi Solomon; Rosenau, Thomas; Nagawa, Christine Betty; Böhmdorfer, Stefan
This study reports large microplastics found in Lake Victoria through an analytical workflow that combines the complementary methods stereomicroscopy, micro-Fourier transform infrared (µ-FTIR) spectroscopy and pyrolysis gas chromatography-mass spectrometry (Pyr-GC-MS) for the quantification of 11 environmentally relevant microplastic polymers. Algae-rich surface water samples (n = 18) were trawled using a 0.3 mm manta net from Lake Victoria, the world’s largest tropical lake. Stereomicroscopy as a determinant analytical technique detected 191 particles, which were primarily blue fragments and fibres. Polyethylene and polypropylene were the dominant polymers identified by µ-FTIR. Pyr-GC-MS allowed the detection and quantification of microplastics (MPs) with LOD and LOQ of 0.01–14.7 µg and 0.03–49.1 µg. Polyethylene (0.058–0.34 µg/L), polypropylene (0.024 µg/L and 0.043 µg/L), nylon 6 (0.0051–0.064 µg/L), nylon 66 (0.0022–0.084 µg/L), poly(ethylene terephthalate) (0.0029–0.027 µg/L) and poly(methyl methacrylate) (0.0036 µg/L) were quantified. µ-FTIR was found to be suitable for the identification of the most abundant polymers in the 0.3–4.9 mm size range whereas Pyr-GC-MS afforded the quantification of seven polymers, most of which were not detected by µ-FTIR. This complementary workflow gave a wider perspective on MP loading, providing both polymer concentrations and physical characteristics (sizes, colours, forms and count) of the MPs.
Parents’ participation in education of children with cerebral palsy in Ongino sub-county, Kumi district, Uganda
(Kyambogo University (Unpublised work), 2025-10) Alupo, Caroline
The purpose of the study was to examine parents’ participation in the education of children with cerebral palsy in Ongino Sub-County, Kumi District. The objectives of the study were; to establish parents’ understanding of the education of children with cerebral palsy, to examine the education support parents give to children with cerebral palsy, to examine the challenges faced by parents in supporting the education of children with cerebral palsy, and to explore how parents can be empowered to effectively support the education of children with cerebral palsy. The study, guided by the Social-Ecological Theory, employed a qualitative research approach supported by a case study design. Data were collected using an open-ended interview guide from 22 purposively selected participants, including 10 parents of children with cerebral palsy, 6 teachers from inclusive UPE schools, and 6 pupils with cerebral palsy. The study ensured rigor and trustworthiness by adhering to qualitative criteria: credibility, dependability, confirmability, and transferability, through participant engagement, detailed documentation, audit trails, rich contextual descriptions, and peer debriefing, producing reliable insights on parents’ participation in the education of their children with cerebral palsy. The study findings revealed that most parents of children with cerebral palsy have a clear understanding of their children’s educational needs and actively ensure their participation in both academic and non-academic school activities. The findings also revealed that parental involvement goes beyond meeting basic needs such as feeding, security, and psychological support, extending to moral, material, and financial assistance, often sourced domestically before seeking external support. Additionally, parents face significant challenges, including poverty, illness, high educational costs, limited knowledge of their roles, and lack of awareness of effective support strategies. Lastly, the study revealed that empowering parents improves their ability to make informed decisions, support their children independently, implement educational strategies effectively, and enhance overall educational outcomes for children with cerebral palsy. The study recommends strengthening parental understanding, enhancing educational support, addressing economic and informational challenges, and empowering parents through training, community programs, and collaboration with schools, NGOs, and development partners to sustainably support children with cerebral palsy.
