Item Teachers' perceptions of public employees' performance management Information system effectiveness in government secondary schools in Mzumbe Ward, Tanzania(African Quarterly Social Science Review, 2024) Komba, Mercy M.The Public Employees' Performance Management Information System (PEPMIS) was the focus of this study, which evaluated its effectiveness in government secondary schools in Mzumbe Ward, Tanzania. The expectancy theory guided the study, which provided a framework for understanding employee motivation and behaviour. A qualitative case study design was used, involving qualitative interviews with 13 teachers purposively sampled from Mongola and Mzumbe Secondary Schools. Data saturation determined the sample size. Thematic analysis was used to analyze data. The findings reveal that while PEPMIS enhances administrative efficiency and supports professional development, its effectiveness is hindered by challenges related to fairness, transparency, training, technical functionality, and network reliability, necessitating improvements for greater usability and satisfaction. Addressing these challenges through targeted interventions can enhance the system's effectiveness, user satisfaction, and overall impact on organizational performance. The study recommends training programs for teachers and school administrators, addressing technical infrastructure issues, and incorporating feedback mechanisms into PEPMIS to make it more responsive to teachers' needs and expectations. This paper contributes to the understanding of PEPMIS from teachers' perspectives. It highlights important insights for policymakers and educators in improving PEPMIS implementation and its impact on the country's education sector.Item Usability and challenges of cloud storage: Perspectives of academic staff at Mzumbe University, Tanzania(East African Journal of Education and Social Sciences, 2024) Komba, Mercy Mlay; Komba, Gabriel VitusThis study aimed to explore the perspectives, preferences and challenges of Mzumbe University faculty regarding cloud storage adoption. Utilizing a case study design, the researchers conducted semistructured interviews with a purposive sample of 15 faculty members to capture diverse viewpoints. The study used the thematic analysis approach to analyse the data retrieved from interviews. Based on the findings, the study concluded that cloud storage systems have several advantages, such as easy accessibility features, robust security protocols, service compatibility and intuitive user interfaces. These benefits encourage academic personnel to collaborate and increase productivity. However, some challenges existed. These are related to internet access, cost, lack of formal training and security. The study recommends that enhancing the university internet infrastructure is critical to guaranteeing reliability and fast connectivity for effective utilization of cloud storage. The university may also think of offering financial assistance for supplementary storage requirements to academic staff.Item Factors for e-government adoption: Lessons from selected African countries(UNISA Press, 2012) Komba, Mercy Mlay; Ngulube, PThis article discusses various problematic issues of providing access to, and promoting the wider utilisation of government information as important factors in e-government adoption. The Tunisian, Mauritian and Egyptian e-government experiences are examined in this article in order to highlight both good practices and remaining challenges in e-government adoption. Some of the good practices that we can benefit from, may be summarised as: formulating a viable national information and communication technology strategy (ICT-based) for modernising the telecommunications infrastructure, developing a regulatory framework for the deployment of a digital economy, obtaining international cooperation in ICT, developing skilled human resources management in ICT, developing a national digital culture in order to overcome the problems of low individual usage and adoption of ICT, establishing an information infrastructure to connect the various local government authorities, and establishing security standards in order to address threats. The study concludes that overcoming the obstacles of providing access to, and promoting the wider utilisation of government information, remain some of the biggest challenges for any government planning to adopt and implement e-government.Item Government information seeking behaviour of citizens in selected districts of Tanzania(Journal of Library & Information Science, 2016) Komba Mercy Mlay; Lwoga Edda TandiThe study assessed the information needs and information-seeking patterns of citizens in Tanzania, focusing on three districts: Morogoro town, Njombe and Kinondoni districts. A questionnaire survey was self-administered to 450 citizens in selected districts, with a rate of return of 99.6 per cent. Findings revealed that citizens mainly required information on national examination results, followed by information on birth, death and marriage certificates, land, and health. Citizens relied on electronic sources and interpersonal communication with neighbours and friends more than explicit sources of information. Certain demographic factors related to education level and respondent’s age determined the use of various types of information sources. Common barriers of citizens’ information seeking behaviour were related to poor ICT infrastructure, difficulty in retrieving information, distant location and high costs of information sources. This is a comprehensive study that provides findings which might help the government in Tanzania and other countries with similar conditions to provide effective government information and services to their citizens.Item Factors that influence eBusiness adoption in selected districs in Tanzania(International Conference on eBusiness, eCommerce, eManagement, eLearning and eGovernance (2015): 1-19. Print., 2015) Komba, Mercy Mlay; Ngulube, PPurpose-Tanzania government has been making efforts to provide its information and services through internet. However, e-government adoption has been quite slow. Few publications explore e-government adoption in the Tanzanian context; therefore, this paper aims to assess factors that influence citizen adoption of e-government in Tanzania.Design/methodology/approach- A survey was administered to elicit factors for e-government adoption in Tanzania. Findings- The results of multiple linear regressions indicate that social influence and system quality significantly influence e-government adoption in Tanzania. Research limitation/implications- In light of these findings, researchers should conduct a similar study using other different e-government adoption models to identify more factors that influence e-government adoption in Tanzania. Practical implications- Policymakers and e-government project teams should consider these factors to facilitate e-government adoption within theItem The influence of ChatGPT on digital learning: Experience among university students(Global Knowledge, Memory and Communication, 2024) Komba, Mercy MlayPurpose This study aims to investigate the influence of ChatGPT, an AI-based chatbot, on the digital learning experience of students at Mzumbe University.

Specifically, the study investigated major predictors of actual usage and continued usage intentions of e-learning system, and challenges of using the e-learning system. Design/methodology/approach – Data were collected through a questionnaire survey of 300 third year undergraduate students, with a rate of return of 77 per cent. A total of 20 faculty members were also interviewed. The unified theory of acceptance and use of technology (UTAUT) was utilized in the study. Findings – The results show that actual usage was determined by self-efficacy, while continued usage intentions of web-based learning system was predicted by performance expectancy, effort expectancy, social influence, self-efficacy, and actual usage. Challenges for using web-based LMS were related to information and communications technology (ICT) infrastructure barrier, LMS user interface was not user friendly, weak ICT policies, management and technical support, limited skills, lack of awareness, resistance to change, and lack of time to prepare e-content and use the e-learning system. Practical implications – The study findings are useful to e-learning managers and university management to identify important factors and develop appropriate policies and strategies to encourage long-term usage of e-learning systems for future studies and lifelong learning. Originality/value – By using UTAUT in the context of continued usage intentions and the integration of an additional construct (“self-efficacy”), the extended UTAUT model fits very well in the web-based learning systems in Tanzania, in particular where such studies are scant. The findings can be used in other institutions with similar conditions in investigating the continued usage intentions of e-learning systems.Item E-government adoption in developing countries: Trends in the use of models(ESARBICA Journal, 2011) Komba, Mercy Mlay; Ngulube, P.Like the evaluation of all other information systems initiatives, the evaluation of e-government in both theory and practice has proven to be important and complex. The importance of e-government evaluation is due to the enormous investment put in by governments for delivering e-government services and to the considerable pace of growth in the field of e-government. However, despite the importance of the evaluation of e-government services, the literature shows that e-government evaluation is still an immature area in terms of development and management. The main aim of this article is to explore various theories and models which have been used in the developing countries context to evaluate e-government adoption. Developing countries suffer from poor citizen utilization of e-government initiatives. An assessment of various theories and models for e-government adoption in developing countries may positively contribute to enhancing government understanding of the factors that influence citizen utilization of e-government systems. Moreover, the understanding of these models can be used as means for providing valuable feedback for the planning of future e-government initiatives in the developing countries.Item Diversity in employment of electric commercial vehicles in urban freight transport: A literature review(Bremen: Bundesvereinigung Logistik (BVL), 2018) Wang, Molin; Thoben, Klaus-Dieter; Bernardo, Marcella; Daudi, MoriceEmployment of Electric Commercial Vehicles (ECVs) constitutes measures to achieve sustainable Urban Freight Transport (UFT). Despite a critical need for ECVs, in industry, the market penetration of ECVs in UFT has remained relatively low. To increase such market penetration, one crucial issue to consider is to obtain a satisfactory match between characteristics of ECVs and requirements of UFT. However, matching diverse types of ECVs and various delivery tasks in UFT leads to many possibilities. The present paper refers to such possibilities as diversity and denotes them as ECV-UFT combinations. Potentials inherent in this diversity seem ignored by the majority of the literature. Therefore, the present paper explores the significance of studying such diversity for the market penetration. In particular, the paper identifies the primary areas of focus and the extent of the diversity already considered in the literature. To accomplish this identification, a Systematic Literature Review (SLR) is applied. The SLR follows a sequence of activities, including selecting sources and keywords, as well as classifying and summarizing results. Findings unveil that the literature has primarily focused on issues concerning the feasibility of ECVs, the adaptation of logistics and vehicle concepts, and support of stakeholders. Furthermore, little consideration of the diversity in the employment of ECVs in UFT is observed as a consequence accounting for the low market penetration. Finally, building on the diversity to increase market penetration, the paper proposes to extend ECV-UFT combinations in the outlined primary areas of focus as future research work.Item Behavioral factors influencing partner trust in logistics collaboration: a review(Springer Berlin Heidelberg, 2016) Daudi, Morice; Hauge, Jannicke; Thoben, Klaus-DieterLogistics collaboration has emerged a prevalent strategy to mitigate challenge individuals and organizations encounter. A successful collaboration, however, depends on certain trustworthy behaviors partner exhibit. To that end, understanding aspects constituting behavioral uncertainty and mechanisms by which such aspects affect partner trust is a necessary. This necessity counts on emergent behavioral trust uncertainties, constituted by partner’s actions and interactions occurring during collaboration. While this is a necessary requirement, most of the studies in the literature lack to take into account the influence of behavioral uncertainty on collaboration and partner trust. To that effect, this paper uncovers outlined limitation by establishing behavioral factors influencing partner trust in operational stage of logistics collaboration. To accomplish this objective, a systematic literature review (SLR) is deployed to consolidate research domains of logistics, supply chain, collaboration, and trust. SLR proceeds by defining a review protocol, followed by a search process conducted in 5 databases using 20 search terms on articles published between 2001 and 2015 inclusively. Among findings this SLR has revealed are four behavioral factors and thirteen criteria proposed to affect partner trust. Additionally, these factors constitute success and measurable criteria needed for empirical investigation which may employ experimental and/or case-study methods. Moreover, synthesized factors extend further an understanding of behavioral trust in ad hoc collaborative networks, a large part of which being supported by networks of humans and computers.
