    Biometric Authentication in Financial Institutions: The intention of Banks to Adopt Biometric Powered ATM
    (Advances in Computer Science: an International Journal (ACSIJ), 2016-07) Mandari, Herman; Koloseni, Daniel Ntabagi
    The main purpose of this study was to assess the intention of banks to adopt biometric powered ATMs in Tanzania’s financial sector. The study adopted Electronic Data interchange (EDI) model and extended it by introducing perceived risks in order to address the issue of risk which is mostly considered as the main barrier in implementing various technologies. The study used a sample of 47 banks, using ATM in Tanzania, and a multiple respondent’s technique was used to collect 102 valid responses. Multiple regression analysis was used to analyze the data; the empirical result shows that external pressure and perceived benefit are positively influencing the adoption of biometric powered ATM while perceived risk has negative influence. However, organization readiness was found to be insignificant in this study. This study has provided a more holistic understanding on the factors affecting adoption of biometric powered ATM which may enable various banks managers to adopt and implement biometric powered ATMs in Tanzania’s financial sector.

    (International Journal of ICT Research in Africa and the Middle East, 2020-06) Mandari, Herman; Koloseni, Daniel Ntabagi
    The study examines the intention to continue using mobile banking services among SMEs in Tanzania. The study extended the ECS-IS model by adding three variables: ease-of-use, perceived trust, and attitude to address the existing challenges in continuance usage of mobile banking services. Data was collected using a self-administered questionnaire from company’s owners and managers. A total of 287 responses were used in data analysis. SEM technique was employed to evaluate the measurement and structural models. The study found that satisfaction and attitude have a direct influence on continuance usage of mobile banking among SMEs in Tanzania. Furthermore, confirmation, perceived trust, and perceived usefulness have an indirect effect on continuance usage of mobile banking services among SMEs. The study provides useful insights which could be used by mobile banking service providers to improve banking services delivered through mobile technology.

    The practice of information security: an analysis of government employees in Tanzania using the Health Belief Model (HBM)
    (Universiti Tunku Abdul Rahman, 2017-11) Koloseni, Daniel Ntabagi
    E-Government information systems need to be protected to ensure secure delivery of information services to the citizens. Lack of information security awareness, poor perceptions with regard to the susceptibility and severity of information security attacks, benefits and barriers of practicing security behavior and poor information security habits among Tanzania government employees, jeopardize the success of the e-government initiatives in Tanzania. To address the above issues, this study extends and uses the Health Belief Model (HBM) as a foundational research model of the study. To measure hypothetical relationships between the constructs of the research model, the study employed the structural equation modelling (SEM) technique. Process macro was used to test the mediation relationships. Data were collected using questionnaires from the government employees tasked to operate the e-government information systems. The study found that perceived severity, perceived susceptibility, perceived barriers, cues to action and information security habits, were key determinants iv of intention to practice information security behaviors. In addition, intention to practice information security was the key determinant of the actual practice of information security. Mediation analysis results indicate that perceived severity construct mediates the relationships between the level of education of the government employees and intention to practice information security behaviors. In order to motivate government employees to practice the acceptable information behaviors, policy and decision makers should invest more efforts in increasing the intention of government employees to practice information security and its respective determinants. To achieve this, information security training, education programs, information security awareness campaigns, rewards, sanctions, dialogue between employees and security experts and cues should be used. This study contributes to the body of knowledge in the following ways: 1) extending the model by adding two variables; information security habits and actual practice of information security behaviors, 2) examining the mediation effects of individual perceptions on the relationships between education level and intention to practice information security behaviors and 3) addressing the knowledge gap on paucity of studies which measures the influence of information security habits on the intention to practice information security behaviors.

    The Role of Personal Traits and Learner’s Perceptions on the Adoption of E-learning Systems in Higher Learning Institutions
    (The African Journal of Finance and Management, 2017-01) Koloseni, Daniel Ntabagi; Mandari, Herman
    This paper investigates the role of personal traits and learner’s perceptions through the lens of Technology Readiness Index (TRI) and Unified Theory of Acceptance and Use of Technology (UTAUT). Data were collected using questionnaire from students in six (6) higher learning institutions in Tanzania. Data analysis employed a structural equation modelling (SEM) technique. The study found that optimism, and discomfort constructs have an influence on effort expectancy and performance expectancy of e-learning systems, while insecurity has an influence on effort expectancy only. Furthermore, the study found that effort expectancy and social influence have positive influence on intention to adopt e-learning systems, while intention to adopt e-learning systems has significant relationship with actual usage of the systems. The study recommends higher learning institutions to develop e-learning policies that focus on improving effort expectancy, awareness of the benefits of elearning systems, encouraging social pressure and behavioral intention to lure more students to adopt e-learning systems. These policies should also take into account a leaner’s personal traits such as optimism, discomfort and insecurity to make them effective.
