    Statistical Modelling of Inflation Rate and Economic Stability in Uganda (1989-2022)
    (2024) Abdirahman Abdi Nor
    This study examines the impact of inflation rates on key indicators of economic stability in Uganda from 1989 to 2022, focusing on growth domestic product (GDP) growth rate, trade, balance of payments (BoP), and investment. Using a cross-sectional and ex-post facto research design, time series econometric techniques were applied to analyze the relationships between inflation and these economic variables. Descriptive statistics indicated a minor symmetry in the data, with average inflation rates at 6.33%, trade at 37.14%, BoP at -1.77%, investment at 2.94%, and GDP growth at 6.5%. Stationarity tests showed that all variables became stationary after first differencing, enabling the use of co-integration analysis. However, the results from the unrestricted co-integration trace rank test revealed no long-term relationship between inflation and economic stability. Regression analysis demonstrated that inflation had a moderate negative effect on GDP growth, accounting for 17.3% of its variability. Inflation also significantly impacted the balance of payments, contributing to 58.6% of its variation. The influence of inflation on investment was less pronounced, explaining only 10% of its change. In the short run, a statistically significant relationship between inflation and economic stability was observed, as confirmed by the Error Correction model(ECM) and bound tests. In the long run, inflation had a negative but statistically insignificant effect on Uganda’s economic stability. The findings highlight that inflation adversely affects economic stability, with more substantial impacts on the balance of payments and GDP growth. The study recommends policy measures to control inflation in order to promote long-term economic stability in Uganda.

    Modelling of key performance indicators for staff advancement in higher institutions of learning using fuzzy logic technique
    (Kampala International University, School of Computing and Information Technology (SCIT), 2019-04) Peter, Ese Ruth
    Performance appraisal is a formal management system that provide for the evaluation of the qualities o1 an individual’s performance in an organization. One of the viable means of motivating staff in higher institutions of learning is to ensure that staff are rewarded with promotion and other benefits as at when due in practice, this is not automatic as staff advancement is usually based on a number of criteria or indicators that should be aggregated to achieve a fair and transparent judgment. However, the judgment is subjective and not transparent in many higher institutions of learning. The objective of this study, therefore, is to model some key performance indices required to achieve staff advancement in a typical higher institution of learning using a transparent approach. The concept of fuzzy logic techniques being a knowledge representation approach is used in this study, and in the process, the required attributes are identified, transformed and modeled. Specifically, the method follows the following procedures: fuzzifications, application of the fuzzy operators, rule generation, aggregation of the rule output and defuzzification. The implementation is carried out in Matlab software environment and in the process a number of rules were generated, The study shows a standard way of representing staffs achievements to pave way for advancement by following procedures that is free of subjectivity, This study further illustrates graphically the surface view of the relationship that exists among the indicators and the output (decisions); the surface view unveils a resulting output that is directly proportional. By using an interactive interface, it is recommended that the rules generated and other models represented in this study should be developed to a system using any suitable high level language. As an extension of this work, the model developed can achieve a learning capability if the technique of neural network is introduced to the fuzzy logic technique used.

    Database -driven and web-based information systems: Harnessing the Maturity of Free and Open Source Software (FOSS) in the Design and Implementation of Information System: case study: school of computer studies-KIU
    (Kampala International University, School of Computing and Information Technology, 2006-10) Kimani, J.; Njoroge
    Many organizations fail to connect business requirements with Information System development and acquisition. This disconnect is especially troublesome for database driven and web-based Information Systems because they are pervasive and critical to the operation of an organization. The resulting Information systems are slow, buggy, hard to maintain, and awkward to evolve. This disconnect is compounded further by the complexity of the platform on which the application is developed and on which it is implemented — a phenomenon that brings about the distinction between proprietary software and Free and Open Source Software (FOSS). Proprietary software has dominated the largest percentage of the world market. It is not possible to change the source code or even get access to it. Once it is developed, there is very limited customization that can be done on the original product. To acquire and use it, in most cases, one needs to purchase a licence. It is this drawback that has changed the trend and has forced many software developers and designers to embrace the Free and Open Source Software (FOSS). This, however, begs the question: Have Free and Open Source Software(FOSS) matured to a level of developing effective and efficient Information Systems? Our research has tried to answer the above question by looking at how an Information System can be developed using FOSS tools: MySQL, PHP and APACHE. To model the system at the conceptual level, we have used Object Oriented Modeling Methodology (ORM). ORM helps us to examine the information in terms of simple elementary facts. By examining the model in terms of natural concepts, like objects and roles, ORM provides a conceptual approach to modeling unlike Entity-Relationship(ER) diagrams, which do not use natural language in its mode and cannot be populated with fact instances.The research reveals that the developed Information System has the three attributes of an effective and efficient Information System: namely, reliability, stability and scalability. Therefore, given a chance, non-proprietary software performs equally well and in some cases better than the proprietary software

    Information, communication and technology (ICT) usage for District service delivery enhancement case study: local district administration (Kampala District- Uganda)
    (Kampala International University, School of Computing and Information Technology, 2006-10) Nalubega, Concepta; Maria
    New information and communication technologies can make a significant contribution to the achievement of good governance goals. This re-governance’ can make governance more efficient and more effective, and bring other benefits too. This paper aims to construct theoretical framework for ICT usage in service delivery for local district administration. It outlines the three main contributions of c-governance: improving government processes (c-administration); greater and more active citizen participation (c-democracy); and connecting citizens (e citizens and c-services). It also investigates the level of ICT usage in local district administration and the challenges of ICT usage faced by local district administration

    The adoption information and communication technologies (ICTS) in small and medium enterprises in Uganda: case study small and medium enterprises in Kampala
    (Kampala International University; School of Computing and Information Technology, 2006-10) Musonge, Message
    There have been innumerable studies of the benefits and problems associated with the adoption of Information and Communication Technologies (ICTs). Unfortunately, few studies have focused on the Small and Medium business Enterprises (SMEs), for whom the adoption rate of ICTs is far slower than for their larger counterparts. This study assessed how the adoption of ICTs in SMEs can facilitate operations and enhance business strategies for the development and enhancement of the economy of Uganda as a whole. From the research carried out in selected business enterprises within Kampala City, Uganda's capital, it argues that the SMEs, being the dominant sector of the economy, like in other developing countries, could be transformed through the adoption of ICTs. The study looked into those factors influencing ICT adoption for companies and how the government has facilitated its use. It also pointed out those needs that were identified and how to address them. Questionnaire survey was conducted to study the adoption of ICTs for SMEs in Uganda. Discussed are the adoption constraints for SMEs' and focus on the requirements gathering process relating to the development and implementation of a Web Portal initiative. The ICT needs were identified and a suggested training design guide was laid out for the entrepreneurs to show them how digital technologies are instruments for developing business skills, getting more productive information to conduct and expose businesses locally and globally
