An Assessment Of The Usage And The Improvement Of Interlocking Stabilized Soil Block Technology - A Case Of Northern Uganda
(International Journal of Technoscience and Development, 2014) Owino, Ejem Noel; Lating, Peter Okidi; Alinaitwe, Henry
Northern Uganda is recovering from civil wars which have left communities without adequate housing. Attempts to introduce Interlocking stabilized soil blocks (ISSB) provide low cost housing haven‟t been very successful. The main purpose of the study was to find ways of encouraging use of ISSB. The study was both an experimental study and a survey. Tests were done on soil and block samples from projects selected from the region in the districts of Gulu, Amuru, Pader, Kole, Lira and Oyam. Questionnaires were also given to Engineers,Technicians and craftsmen from the same study location and data collected were analyzed using the Statistical Package for Social Sciences (SPSS) to test, rank and correlate them. Tests on soil samples and block samples indicated that they are of generally acceptable quality and strength however, water absorption was generally high. Low incomes and low durability of the blocks were found to be the greatest barriers, whereas the greatest enablers are the fast speed of erection, and environmental friendliness. It is recommended that: UNBS commission ISSB standards; government provides more funding; policies are developed that promote the use of ISSBs: and more research is done on the durability of the ISSBs.
Cluster Development in Low Resource Settings: the Case of Bioethanol and Fruit Processing Clusters in Uganda
(Journal of Entrepreneurship and Innovation Management, 2013) Ecuru, Julius; Trojer, Lena; Lating, Peter Okidi; Ziraba, Yasin Naku
In this paper, bioethanol and fruit processing clusters in Uganda were taken as sectoral innovation systems, and enabling conditions and barriers to their growth analysed from a technoscientific and innovation systems perspective. Active participation of entrepreneurial university scientists in the clustering process appears to be an enabling factor. Absence of goals and incentives for investing in the cluster areas and for driving formation of markets for cluster products is a major barrier. Adopting more inclusive innovation policies, and having in place good community engagement strategies, could help overcome the barriers and expand opportunities for clusters in low resource settings to grow and become competitive.
Duning in Rills on Unpaved Roads in Uganda
(Journal: Journal of Advances in Mathematics, 2014) Semwogerere, Twaibu; Lating, Peter Okidi; Kucel, Samuel Baker
Dunes on non-paved roads develop as a result of general construction designs especially in the drainage. They are active features which block up drainage rills and parts of the roads causing road rutting, deep mudding and flooding. Shear stress, erosion, and deposition due to the discharge were the main factors in the equation formation and analysis. An equation is constructed to determine their formation and effects on gravel road dunes. It is finally tested with a numerical example using cross-sectional field and laboratory results data. Various experiments like sieve analysis, measuring road dune sizes with respect to slope size, rain intensity, and road widths were used in the formulation and evaluation of the equation for this study. Key findings of this paper include among others dune formation rates in road rills and possible timely control. The model equation constructed is expected to help in various road design and maintenance practices.
Exploration of Gravel Roads Erosion Data in Uganda
(Intl. Conf. On Advances in Computing, Electronics and Electrical Technology, 2015) Semwogerere, Twaibu; Lating, Peter Okidi; Kucel, Samuel Baker
The main objective for this study was to explore the erosion data from across Uganda gravel roads. Gravel/dirt/rural roads constitute a larger part of the total road networks in developing countries and are top-listed for accumulation of wealth for such countries like Uganda. Generally, quantitative methods through experimental designs were used. Data was generated from various experiments and STATA output and used in the analysis and exploration. They include among others sieve analysis, measurement of road rill/dune sizes, Atterberg tests, and dry-density tests. These were conducted to reflect the characteristics of road subgrades and sediments from these roads. A brief comparison of one of the original erosion models, USLE/RUSLE was done with the erosion model developed for the maintenance of gravel roads, EMMOGR and conclusions reached.
Factors Affecting The Development Of Effective Water Resource Management Policies: The Case Of The Management Of Lake Victoria Basin In Uganda
(African Journal of Environmental Science and Technology, 2020) Odongtoo, Godfrey; Ssebugwawo, Denis; Lating, Peter Okidi
Partial least square-structural equation modelling (PLS-SEM) was used to evaluate the factors affecting the development of effective water resource management policies. Researchers employed a purposive sampling method to come up with the most suitable respondents. The sample size of 152 respondents was computed from a population size of 245 water experts within Lake Victoria Basin (LVB) in Uganda. The questionnaire was self-administered to 152 respondents to dig out their views based on their experiences in water resource management. The authors aimed to find out the relationship between efficiency of water allocation, natural hazards and risks, stakeholders’ participation, governance and decentralization, socio economic activities and effective water resource management policies. The findings of this study revealed that governance and decentralization, natural hazards and risks, and socio-economic activities had a significant positive effect on effective water resource management policies. Governance and decentralization had the highest path coefficient (β= 0.453 and p-values = 0.000). The R2 value was scored at 0.680, which collectively explained 68% of the overall variance in the development of the policies. The study recommends putting special attention on governance and decentralization for effective water resource management policies. These findings can support practitioners and decision makers engaged in the management of water resources within LVB and other water bodies worldwide.
Hybrid E-Learning for Rural Secondary Schools in Uganda: Co- Evolution in Triple Helix Processes
(Second International Conference on Advances in Engineering and Technology, 2009) Lating, Peter Okidi
Rural secondary schools in Uganda perform poorly in Science and Mathematics due to lack of functional science laboratories and libraries. Furthermore, it is difficult for such schools to attract and retain good, committed and qualified Science and Mathematics teachers. Arua is one such District. It has two advanced level girls’ secondary schools- Muni and Ediofe. Hybrid e-learning was introduced in both schools for the benefit of 29 students who were taking either Mathematics or Physics or both. Local content for the production of interactive multimedia CD-ROMs were developed based on the national syllabus using senior teachers from Makerere College School in Kampala. The students effectively used the CDs for six months in 2007 and were repeatedly externally examined by Makerere College teachers, Arua District Examinations Committee and the Uganda National Examinations Board. The longitudinal data collected were analysed using multilevel methods. The results showed that 41% of the students passed and were eligible for university admission. However, after extrapolation of the performance of the students over twelve months, up to 72% of the students would have passed. The paper is discussed by linking the study to its contribution towards the achievement of international and national obligations of Uganda. Co-evolutions of the study into triple helix processes and ‘Mode 2’ knowledge production are also discussed. The paper concludes that it is possible to implement hybrid e-learning financially constrained rural secondary schools. However, when carrying out research in the context of the problem, co-evolutions in triple helix processes and Mode 2 production of knowledge are likely to happen.
An Integrated Solution For An Integrated Water Resource Management Of Lake Victoria Basin (LVB)
(Annals of Valahia University of Targoviste. Geographical Series, 2019) Odongtoo, Godfrey; Lating, Peter Okidi; Ssebuggwawo, Denis
Lake Victoria Basin is a very important resource for the five riparian countries: Uganda, Kenya, Tanzania, Rwanda and Burundi. The Lake Victoria Basin provides resources for fishing, agriculture, medicine, forestry, water transport and other economic activities. However, its surrounding is affected by population growth, urbanization, industrialization, increasing commercial activities and inadequate provision of sanitation services among others. These grossly affect the landscape and water resources around the lake basin. In this paper, a web based integrated solution prototype is presented. The system consists of web access, mobile access, web service handler, mobile service handler and a database. It can be used to address communication challenges by enhancing stakeholder’s participation, information sharing and enforcement of laws by timely communication and coordination of activities of good governance. The test results confirm that the system is effective and can be used to operate in real world environment in the management of water resources by providing the key actors with relevant information to facilitate decision making.
Interactions between Public Research Organizations and SMEs: A Case of Uganda Industrial Research Institute
(International Journal of Technoscience and Development, 2015) Nakamatte, Olivia; Lating, Peter Okidi; Muyanja, Charles
Knowledge Translation (KT) is important to understand how knowledge is transformed to economic value. This paper seeks to scrutinize the synthesis, dissemination, exchange and application of knowledge produced by Uganda Industrial Research Institute (UIRI). Theoretically, the study relates to the area of public research organizations (PRO) – industry linkages with regard to knowledge uptake by the SMEs in LDCs. Through a case study approach, this paper contributes to the field of KT by discussing how interactions affect the usefulness of knowledge produced by research organizations. The study is based on original data collected through interviews carried out with UIRI researchers between November 2012 and January 2013. Knowledge Translation Indices were developed for sample projects. The findings revealed that both Mode 1 and Mode 2 types of knowledge generation existed, with the former leading to underutilization of knowledge or wasted results. Generally, KT is complex and cannot be achieved through linear relationships, thus, the study concludes that more interactions with the indigenous agro-processing SMEs will lead to industrial development.
Longitudinal Analysis of Performance of Ugandan Rural Advanced- Level Students in Physics Practicals
(Second International Conference on Advances in Engineering and Technology, 2011) Lating, Peter Okidi
Hybrid e-learning was applied in two typical rural girls’ advanced-level secondary schools (Ediofe and Muni) in the rural district of Arua. The intervention was meant to support the learning and teaching of Physics and Mathematics. Multistage sampling was done to identify 19 participants from both schools in advanced-level Physics Practicals. As the project progressed, the students sat four repeated external examinations in May, June, July and September 2007. Individual growth models were used to analyse the performance data. The intraclass correlation was found to be 32% which meant that 68% of the variability in scores is attributable to withinperson factors. The hybrid e-learning was found to contribute 64% of a student’s scores, making it a very viable proposition for disadvantaged rural schools. These results were discussed in light of the Ugandan national policies on science education.
Longitudinal Analysis of Performances of Beneficiaries of Affirmative Action Policy in Higher Education: A Case of Female Engineering Students of Makerere University in Uganda
(Intl' Conference on Advances in Engineering Sciences and Applied Mathematics, 2014) Lating, Peter Okidi
In order to improve the participation of women in higher education, in 1990 Government of Uganda introduced 1.5 bonus marks for every female student applying for vacancies in public universities and other tertiary institutions. The policy has remained in force up to now. However, no systematic study has been done to demonstrate how the beneficiaries of the Government affirmative policy perform while they are in the universities. Makerere University, the most dominant public university in Uganda, has been implementing the policy from 1990/1991 academic year. The aim of the study was to investigate the changes in the performances of the female engineering students of Makerere University, College of Engineering, Design, Art and Technology (CEDAT) for the entire four-year duration of their stay on the engineering programmes. From the office of the Senior Academic Registrar of CEDAT, 30 female students who were admitted into Mechanical, Civil and Electrical Engineering programmes in 2004 were identified. Of these, 11 were found to be beneficiaries of the 1.5 bonus marks. The Cumulative Grade Point Average (CGPA) of each of the participants in the study was collected. For successful students who finally graduated from the University, eight sets of results were collected. Multilevel analysis methods were used for the analysis of the longitudinal data collected. Three models were specified: the fully unconditional means model (Model A), the fully unconditional growth model (Model B) and the fully conditional model (Model C). The models were fitted to data. Deviances of the models were calculated. To answer the researchquestion, the models B and C were compared by getting their deviance differences and were found to be – 26.5 (2 df, p < 0.995). Since  0.995 cal p is > p= 0.05, we failed to reject the null hypothesis at 95% level. The paper concluded that there was no significant difference in performances between the beneficiaries and non-beneficiaries of the 1.5 bonus marks. While at the beginning the female students were admitted on lower grades, their rate of improvement with increasing stay of the programmes was 32% higher that that of the nonbeneficiaries.
A Mobile Application Tool To Mitigate Communication Challenges In Water Resource Management Of Lake Victoria Basin
(4th International Conference Water resources and wetlands, 2018) Odongtoo, Godfrey; Lating, Peter Okidi; Ssebuggwawo, Denis
Lake Victoria Basin is a very important resource for the five riparian countries: Uganda, Kenya, Tanzania, Rwanda and Burundi. The Lake Victoria Basin provides resources for fishing, agriculture, medicine, forestry, water transport and other economic activities. However, its surrounding is affected by population growth, urbanization, industrialization, increasing commercial activities and inadequate provision of sanitation services among others. These grossly affect the landscape and water resources around the lake. In this paper, a web based mobile application tools (MAT) prototype is presented. The system consists of web access, mobile access, web service handler, mobile service handler and a database. It can be used to mitigate communication challenges by enhancing stakeholder’s participation, information sharing and enforcement of laws by timely communication and coordination of activities of good governance. The test results confirm that the system is effective and can be used to operate in real world environment in the management of water resources by providing the key actors with relevant information to facilitate decision making.
Optimal Ordering Policies for Supermarkets under Static Pricing and Stochastic Demand: A Case Study of Milk Powder Product
(International Journal of Scientific Research Engineering & Technology, 2013) Mubiru, Kizito Paul; Buhwezi, Bernard Kariko; Lating, Peter Okidi
Demand uncertainty affects a significant portion of sales revenue in supermarkets. In this paper, we develop a new approach to formulate and optimize the single-item, finite horizon, periodic review revenue problem of milk powder product under stochastic demand. A special case of our model is where sales price and scheduled inventory replenishment periods are uniformly fixed at all supermarkets. Adopting a Markov decision process approach, the states of a Markov chain represent possible states of demand for milk powder product. The decision of whether or not to order additional units is made using dynamic programming over a finite period planning horizon. Numerical results demonstrate the existence of an optimal state-dependent ordering policy and the corresponding sales revenue of milk powder product in supermarkets.
A Technological Innovation Systems Perspective On The Emerging Shea Butter Cluster In Uganda
(IJTD, 2014) Ecuru, Julius; Lating, Peter Okidi
This paper uses a technological innovation systems perspective to analyse the emerging shea butter cluster in east and northern Uganda. The aim of the paper is to describe the structure of the innovation system for shea butter and its associated products. In so doing, it highlights the system‟s functionality and the underlying policy issues affecting growth of the shea butter cluster in the region. Data was collected through interviews with 20 key informants in the shea districts, three focussed group discussions with farmers‟ group leaders, processors, local government officials, private sector and development aid practitioners, and observations of shea butter processing in firms. Findings reveal that shea butter production and processing is very much a cottage industry, which is supported mainly by women groups. It could evolve rapidly into a dynamic business cluster if actors and institutions, which currently exist in isolation, start to interact more intensely It means that local governments, universities, private businesses and the community in the shea districts should be willing to interact and learn from each other. The findings point to the need for universities and research organizations in the area to work collaboratively with local government, businesses and the community to promote growth of the shea butter cluster.
