    An empirical study of critical success factors for the adoption of m-government services in Tanzania
    (Springer Singapore, 2021) Ishengoma, Fredrick; Mselle, Leonard; Mongi, Hector
    For 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.

    Blockchain technology as enablement of industry 4.0
    (IGI Global, 2022) Ishengoma, Fredrick
    Industry 4.0 (also known as smart manufacturing or industrial internet of things [IIoT]) refers to a major change in the way products are manufactured and delivered, with a focus on industrial automation and the flexible factory backed with several technologies that include the internet of things (IoT), cyber-physical systems, and artificial intelligence. Industry 4.0 gave birth to a new age of smart manufacturing, automated supply chain, and personalized goods and services. Meanwhile, the rise in the application of blockchain technology (BCT) in different sectors propels the Industry 4.0 model to extend its scope. This chapter discusses the impact of BCT as the enablement of Industry 4.0. The modified e-Delphi methodology aimed at gathering the opinions of recognized experts was used. The findings present the potential that BCT brings using a case along with emerging issues. Emerging issues such as BCT security, interoperability, smart contract issues, digital twin issues, and ethical issues are discussed, and solutions are proposed.

    Cost-aware virtual USB drive: providing cost-effective block I/O management commercial cloud storage for mobile devices
    (IEEE, 2010) Nam, Young Jin; Park, Young Kyun; Lee, Jong Tae; Ishengoma, Fredrick
    This paper addresses difficulties in mapping blocks onto cloud storage and proposes a novel cost-aware log-structured block I/O management over one of the commercial cloud storage, Amazon S3. The proposed scheme is imbedded in the virtual USB drive architecture that replaces the NAND flash of the USB memory with the capacity-free network storage. The key of the proposed scheme is to perform onto the cloud storage log-structured writes with the optimal number of data blocks that adaptively changes with I/O characteristics (the number of I/O operations and storage size) and cloud storage pricing policy. The proposed scheme also efficiently manages associate metadata by using well-organized data structures and layouts both in the memory and on the cloud storage. Performance analysis shows that the proposed scheme can reduce the total I/O costs significantly up to 54%, as compared with a simple one-to-one mapping scheme.

    Exploring the non-linear trajectories of technology adoption in the digital age
    (Emerald, 2024) Mambile, Cesilia; Ishengoma, Fredrick
    Purpose The objective of this research is to examine the accelerated adoption mechanisms of emerging technologies in information systems. Its goal is to comprehend the drivers behind the prompt assimilation of technology trends such as TikTok, ChatGPT, mobile payment schemes, cryptocurrency and VR. Design/methodology/approach The study follows the systematic literature review methodology (using the PRISMA protocol to guide the selection of scholarly materials from Google Scholar, Scopus and Springer). Specifically, the research draws on identified literature on the adoption trajectories of technologies (ChatGPT, TikTok, cryptocurrency, mobile payment systems, and virtual reality) to systematically assess pertinent insights, and draws on theoretical lenses of Disruptive Innovation Theory to reach interpretations. Findings The study indicates that the prompt assimilation of technology is shaped by several variables such as user-centered design, network effects, content powered through algorithms, viral trends, ease-of-use and accessibility features, engagement levels and retention rates. Research limitations/implications The selection of specific platforms may limit the generalizability of findings. Social implications The emergence of new technologies is causing a shift in societal behaviors and norms, which has significant social implications. While platforms such as TikTok offer opportunities for community-building, there are concerns regarding digital divide and privacy issues that need to be addressed. So understanding the impact of these changes becomes vital for achieving fairness in access and making technology's potential transformation practicalized effectively. Originality/value This research enhances the current body of literature by presenting a thorough examination of the non-linear patterns involved in adopting advanced technologies. By combining knowledge from numerous fields, this study delivers an integrated comprehension regarding what factors prompt swift adoption.

    (The Open University of Tanzania, 2024-01-28) Makolo, Renatus; Ishengoma, Fredrick; Shao, Deo
    Information and Communication Technology (ICT) has recently advanced in education sector where teachers and other educational stakeholders use learning management system (LMS) to improve students learning. Tanzania in the meantime, has implementing multiple initiatives aimed at enhancing ICT integration in education. The initiatives includes connection of National ICT broadband backbone, implementing various ICT projects such as Tanzania Education and Research Network (TERNET) and the use LMS and digital library (DL) through Tanzania Institute of Education (TIE). Apart from the government initiatives, a critical gap exists in the knowledge and proficiency of both tutors and students in utilizing LMS and DL skills to enhance creativity. This study seeks to address this issue by exploring the integration of LMS and DL to preserve the talents and skills of educators and students. The research utilized a mixed-method approach that involved questionnaires and interviews from tutors. Data were analyzed both inferentially and descriptively. The study found that 33% of tutors were competent to ICT skills related to LMS and DLs. Furthermore, the study proposed a digital library system (DiLaS) prototype as a blueprint for integrating LMS and DLs to support students in learning and assessment. The paper recommends that the government should draw policy strategies that support innovation in digital systems to preserve exceptional skills.Keywords: Retention of talented skills, learning management systems (LMS), ICT skills, and digital library

    Memory transfer language as a tool for visualization-based-pedagogy
    (Elsevier BV, 2021) Mselle, Leonard; Ishengoma, Fredrick
    In 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.

    (Lomonosov Moscow State University, 2014) Ishengoma, Fredrick; Mtaho, Adam
    The main delivery system in Tanzanian education has been face-to-face approach relying on printed educational materials. High cost of books and insufficient teaching materials are still the major challenges. Recently, Online Social Networks (OSN) have gained popularity across the world and they are used for sharing information, news, chatting, messaging, and keeping in touch with friends. Studies have shown that OSNs can be used as tools for facilitating learning, supplementing face-to-face approach. Currently, there is an increase in the number of local OSN sites and subscribers in Tanzania. This paper examines to what extent are local OSNs in Tanzania exploited as e-learning platforms. Moreover, it addresses the student’s perceived challenges and discusses the opportunities of using local OSNs towards fostering students' academic development.

    Sustenance of the digital transformations induced by the COVID-19 pandemic response: lessons from Tanzanian public sector
    (Emerald Insight, 2022) Shao, Deo; Mwangakala, Hilda; Ishengoma, Fredrick; Mongi, Hector; Mambile, Cesilia; Chali, Frederick
    The emergency of the COVID-19 pandemic has affected organizations differently, leading to adopting alternative business operation models, including digital technologies. The rapid adoption of digital technologies during the COVID-19 pandemic demonstrates how adaptive technologies intersect with human and social institutions in potentially risky or inequitable ways. However, the sustenance of the digital transformations (DTs) induced by the COVID-19 crisis is still unclear. Thus, this study aims to evaluate the sustenance of DTs accelerated by the emergence of the COVID-19 pandemic response in the Tanzanian context amid the crisis. The study used a qualitative approach that included a literature review and semi-structured interviews with Information and Communication Technology (ICT) personnel from selected public institutions in Tanzania. The interviews elicited interviewees’ perspectives on the following: the digital revolution that occurred during the COVID-19 outbreak; how it affects their work; and the country’s future digital landscape. Additionally, a literature analysis established and generalized the practices used by the governments during the COVID-19 crisis. The results show that there is enormous, colossal press toward adopting digital solutions. The use of digital technologies, such as digital payments, e-commerce, telemedicine and online education, has attracted the attention of businesses and individuals in Tanzania. Consequently, the move has enabled the country to cope with the cascading impacts of the COVID-19 pandemic and progressive economic recovery to achieve its development goals. Furthermore, the findings offer policy strategies for taking the induced DTs to the next level and sustaining it. This study reports the lessons from the DTs induced by COVID-19 and their sustenance. It also contributes toward forward-thinking reforms and policy measures that could help Tanzania and the likes harness the DTs'’ potential in the wake of the pandemic.

    Towards academic computer emergency response teams in African developing countries
    (ASCEE, 2021) Mutembei, Leonard; Ishengoma, Fredrick
    The increasing number of cyberattacks on African universities demonstrates the critical need for a more profound shift in perspective from a simple IT problem to the implementation of more resilient security measures and policies, and thus, Computer Emergency Response Teams (CERTs). Fortunately, even though there are numerous CERTs worldwide, there are relatively few studies in the literature that address academic-CERT in the African context. This article summarizes the CERT landscape in African countries and proposes a framework for academic-CERT. The proposed framework aims to fortify African academic institutions' resilient security measures. The paper will serve as a foundation for developing academic CERTs in African countries, which will eventually result in the implementation of national CERTs and the protection of online users.

    Value co-creation (VCC) and value co-destruction (VCD) via open government data (OGD): Empirical case of Tanzania
    (Wiley & Sons, 2024-02-19) Ishengoma, Fredrick; Shao, Deo; da Silva, Raphael Gouvea; Wiedenhoft, Guillherme Costa; Alexopoulos, Charalampos; Rizun, Nina; Saxena, Stuti
    Having emphasized upon the potential benefits of Open Government Data (OGD) initiatives via value derivation and innovation pursuits of the stakeholders, it falls in place to complement this line of OGD research in the specific case of Tanzania, a developing country, to support the inferences. Specifically, it is important to understand the manner in which OGD VCC-one of the hinges of OGD initiatives- and OGD VCD-a possible fall out of OGD initiatives-happens to pass. Thus, a content analysis of the interviews of 15 public officials and managers associated directly with the management and operationationalization of OGD initiatives is being done to arrive at the conclusions. Thus, the interviewees aver that OGD Value Co-creation (VCC) may be facilitated on top-priority bases by consistent marketing efforts by the government as also the partnerships with the key stakeholders of the OGD ecosystem, and, among the prominent Value Co-Destruction (VCD) factors may be counted the issues linked with data privacy and resource restriction. Literature on OGD VCC is at a nascent stage and the one on OGD VCD is evolving. As an atypical empirical validation case vis-a-vis the emerging OGD VCC-VCD research, the study is an additional contribution to the extant literature with specific reference to the developing country's experiences.
