- ItemAdoption of e-learning technologies in education institutions/organizations: a literature review(Asian Journal of Educational Research, 2017-10-25) Kimwise, Alone; Jehopio, Peter; Maiga, GilbertAlthough the advent of E-Learning Technologies presents the best cost effective strategy to teaching and learning, the success of these innovations primarily depends on their adoption. Investment in E-Learning Technologies alone by different institutions/organizations is not enough as its full benefits can only be realized from their full utilization. E-Learning Technologies if well utilized have the capacity to enhance students critical thinking, eliminate geographical barriers, support lifelong learning, reduce costs and increase efficiency at education institutions. E-Learning Technologies are technologies which are based on the backbone of ICT infrastructure. For this reason the Information & Communication Technology adoption models are useful in explaining E-Learning Technologies adoption. A number of models/theories which explain and predict user behaviors and intentions to adopt technologies have been advanced. For this discussion the following models were selected and analyzed, Theory of Reasoned Action (TRA), the origin technology acceptance model (TAM), the TOE framework & the revised TAM model.
- ItemAdoption of e–tax services in Uganda: a model of citizen–based factors(Inderscience Publishers, 2013) Maiga, Gilbert; Asianzu, ElizabethDiverse benefits of e–government services are linked to its adoption and usage. E–government adoption rates in economically transiting countries remain low and so its benefits are not fully realised. This is partly due to governments focusing largely on technical supply–side factors with little emphasis on the demand or citizens' perspective of e–government adoption. The result has been a gap between what is offered and what is consumed. This paper presents the results of a study that develops a model for e–tax service adoption as an attempt to bridge the gap for this segment of e–government. Requirements for the model elicited in a field study are used to extend the technology acceptance model (TAM) which emphasizes citizen–based factors for e–tax adoption. The extended model has dimensions of adoption benefits, trust, attitudes, education, compatibility, awareness, accessibility, training, user support and local language use. It is generic and reusable for other countries in similar context.
- ItemBlended learning resources in constrained bandwidth environment: considerations for network and multimedia optimization(ACSIJ .I, 2013) Maiga, Gilbert; Suhail, Nazir Ahmad; Lubega, JudeThe potential of multimedia teaching and learning approach at higher education is well recognized by researchers, as it is a powerful tool to increase the perceived level of user satisfaction, leading to enhance the blended learning process. However, the learning process can be improved significantly by delivering the content using visual media (video, audio, and graphics). On the other hand, such multimedia contents require larger bandwidth for transmission over the Internet, which is limited in developing environments where demand always exceeds the resource. This paper constructs a framework comprising of network optimization and multimedia optimization, as two main components, aimed to improve the multimedia performance in the context of constrained bandwidth environment.
- ItemFactors for adoption of e-learning technologies in Ugandan high education institutions(RJIF, 2016-09-09) Kimwise, Alone; Maiga, Gilbert; Jehopio, PeterThis research identifies the factors that affect adoption e-learning technologies in Ugandan High Education Institutions. Despite the enormous potential that e-learning technologies have in enhancing teaching and learning at Higher Educational institutions, the adoption of such technologies in Ugandan Higher Educational institutions is low. Effective adoption of such technologies requires that a number of issues be taken into account which among these includes technological and individual factors. To attain the objective of this study, a questionnaire was used to collect data from 380 participants (students, lecturers and ICT support) from four Ugandan Higher Education Institutions. Results showed that factors that are affecting adoption of e-learning technologies in Ugandan HEIs were; Patronage, Compatibility, Trialability, Complexity, Relative Advantage, Perceived Usefulness, and Perceived Ease of Use while as Observability factor did not influence behavioral intention to adopt e-learning technologies in Ugandan HEIs. This study concludes that well-designed trainings should be provided for the students, lecturers and ICT support staff to familiarize them with the fundamental knowledge on how to use the e-learning technologies in Ugandan HEIs as well as trial opportunities to build a better understanding in the operational functions.

- ItemFlexible approach for user evaluation of biomedical ontologies(Makerere University, 2008) Maiga, Gilbert; Ddembe, WilliamThere has been an emergence of various ontologies describing data from either the clinical or biological domains. Associated with this are attempts to develop systems that integrate clinical and biological ontologies using various strategies to overcome issues of scope, differing levels of granularity and conflicting user needs. However, lack of knowledge about user needs for such integration systems, and absence of a general framework to assess their suitability for specific application remain obstacles to their reuse and wide adoption in distributed computing environments. This paper describes a study that aims to address this problem by proposing an evaluation framework for ontology integration to suit user needs. The framework draws on existing ontology evaluation approaches in relating user objectives to ontology characteristics. Systems theory is used to explain the dynamics of a biomedical environment. The framework therefore includes feedbacks from the evaluation process to the user characteristics of the integrated systems. This framework was validated by a study using structured interviews and questionnaires in a survey. The results indicate that it is sufficiently flexible for evaluating ontology based biomedical integrated systems, taking into account the conflicting needs of different users interested in accessing complex libraries of biomedical data.
- ItemA knowledge management model for pediatric health care practice: A paper presented at theScience, Computing, Telecomminucations(PACT): Pan African Conference Arusha on 14-18 July 2014(IEEE, 2014) Mutuwa, P.L.; Maiga, GilbertPediatric care practitioners are faced with increasing amounts of knowledge that is not matched by an equivalent ability to manage and apply it for improved healthcare. This is largely attributed to the lack of tools, systems and models that aide in Knowledge Management. The study aimed to describing a model that focuses on integrating the Knowledge Management processes that contribute to improved Pediatric care delivery in the context of Uganda. A field study was conducted to gather requirements for the model. The data collected was analyzed and the results used to extend existing Knowledge Management models in order to describe a suitable model for pediatrics Knowledge Management. The study identified technology, People, Storage and pediatrics knowledge integration as important requirements for successful implementation of Knowledge Management in pediatrics healthcare practice. An evaluation of the proposed model was done and the results indicated its suitability for Knowledge Management in pediatric practice.
- ItemPredicting adoption of Health technology in resource constrained environments: a coference preceedings on 7-9 May 2014 at Le Meridien Ile Maurice 1ST Conference(IEEE, 2014) Maiga, Gilbert; Namagembe, F.Health technology is an important form of Information Technology enabled delivery for health care. However, its adoption and use by healthcare providers faces challenges that include the lack of understanding of what motivates user acceptance and adoption of its applications. In this study, the Unified theory of Acceptance and Use of Technology is used to model the prediction and explain user acceptance of m - health tools in resource constrained en vironments. The model was validated using a descriptive field study The results confirm that performance expectancy, effort expectancy and disturbance concerns as presented in the unified theory for the acceptance and use of technology are important consid erations for healthcare professionals to adopt m - health tools in Uganda. The results also help to validate the Unified theory of Acceptance and Use of Technology as an underlying predictive model for - health technology adoption in similar environments.
- ItemA technique for strengthening weak passwords in electronic medical record systems(Springer Berlin Heidelberg, 2012) Maiga, Gilbert; Kalyango, Samuel TusubiraThe internet has accelerated access to and sharing of electronic medical records (EMR). EMRs are meant to be confidential and only accessed or shared with authorization from the owner. A combination of UserID and a Password is the most widely used mechanism to assure user authentication and access to EMRs. However, these mechanisms have been greatly compromised by guessing and hacking of weak passwords leading to increased cases of medical identity theft, cyber terrorism and information systems attacks. This has resulted in false financial claims, debts due to unauthorized disclosure of the private and confidential EMRs leading to huge losses for the victims. This study developed a technique to strengthen weak passwords that integrates UserIDs, weaker password, salts, challenge responses and random variables to derive a stronger password for authentication. A system prototype to test the technique was built, tested and validated by users.
