Item An empirical study of critical success factors for the adoption of m-government services in Tanzania(Springer Singapore, 2021) Ishengoma, Fredrick; Mselle, Leonard; Mongi, HectorFor the past decade, the Tanzanian government has started implementing m-government initiatives. However, little is known about the factors surrounding m-government adoption in Tanzania. Consequently, some m-government services have been successfully adopted while others are still struggling (having a low level of adoption). In this chapter, the authors investigate critical success factors (CSFs) that favor the adoption of m-government services from a web analytics point of view. The results show that inspecting the web analytics data from multiple viewpoints and varying levels of detail, gives insights on the CSFs towards the adoption of m-government services. The findings suggest that perceived usefulness, user needs, and usability favor the adoption of one m-government service over the other. Moreover, factors like the loading time of the service, the number of requests, and bounce rate seem not to have an effect.Item Developing an intelligent postGIS database to support accessibility tools for urban pedestrians(MPDI, 2018) Sinkonde, Daniel; Mselle, Leonard; Shidende, Nima; Comai, Sara; Matteucci, MatteoPeople with mobility impairment must travel through cities with extra care. An intelligent database of Maps for Easy Paths (MEP) project for storing and retrieving accessibility information about a particular path by using PostGIS may enable the public to enjoy the privilege of the technology that alleviates the problem of city accessibility through the Web or, more recently, through smartphones/tablet applications. The methods and techniques for intelligent database to storeand retrieve accessibility information by using a relational intelligent PostGIS database are described. The conceptual data model is designed for an intelligent database (PostGIS). Users will be able to actively participate in the process of taking pictures of obstacles, uploading them to the MEP server and giving some comments on the attributes of the picture of the barrier. The resulting data will help others to locate and evaluate paths. This paper presents the conceptual data model design as well as a review of features of the data of the existing systems. Therefore, the novelty of this approach lies in developing an intelligent database for the enrichment of geographical maps with information about the accessibility of urban pedestrian areas for people with mobility problems.Item Memory transfer language as a tool for visualization-based-pedagogy(Elsevier BV, 2021) Mselle, Leonard; Ishengoma, FredrickIn this paper, MTL, an approach for visualization-based pedagogy, is analyzed and contextualized in both Cognitive Load Theory (CLT) and Dual Coding Theory (DCT). Through MTL, lectures, tutorials, laboratory sessions and individual study in learning and teaching programming are all carried out using two cognitive channels; verbal and non-verbal. RAM diagrams together with animations are used to visualize (represent the images of) codes, while text and voice are used for verbal presentations. A class experiment was carried out to evaluate the impact of using MTL together with animations in teaching programming. The chi-square test results revealed that, students' performance on one question (question 1) was significantly (p < 0.0001) higher for the experimental group (23.53%) as compared to the control group (1.89%). Similarly, the results of the chi-square test revealed that, students' performance on another question (question 2) was significantly (p < 0.0001) higher for the experimental group (23.53%) as compared to the control group (1.14%). It is concluded that the MTL approach enhances comprehension since it allows the use of two cognitive channels, which, in turn, reduces cognitive load.Item Power distance and users behavior towards the adoption of m-Government services in Tanzania: a web analytics study(Open Information Technologies Lab (OIT Lab), 2019) Ishengoma, Fredrick Romanus; Mselle, Leonard; Mongi, HectorCitizens adoption of m-Government services can be achieved through voluntary or mandatory settings. In Tanzania, some government authorities have chosen mandatory adoption approach in order to increase adoption rate, efficiency, and reduce the costs of public administration. One of the crucial dimensions of mandatory adoption is power distance (PD). Literature review, mostly from developed countries, have shown contradicting results on the role of PD towards the adoption of m-Government services. Meanwhile, there is a lack of research studies from African developing countries. This research seeks to fill this gap by examining if PD is a success factor towards the adoption of m-Government services and model users’ behaviors. The study analyzed the 1-year transactions logs that cover before and after the mandatory electronic payment system is adopted. Furthermore, the study analyzed the 1-year traffic of data from government recruitment agency by using web analytics to understand users’ pattern. Findings show that PD is a significant success factor in the adoption of m-Government services in Tanzania. The study also reveals the existence of flash effect (FE) pattern. Finally, the study proposes a Flash Event Mitigation Algorithm (FEMA) to mitigate the impact of the FEs on m-Government services.
