    Do transparency and accountability enhance regulatory compliance in public procurement? Evidence from Tanzania
    (The University of Dodoma, 2023) Ntangeki, Goodluck G.; Changalima, Ismail A.; Justus, Scholastica N.; Kawishe, Denis C.
    With an increasing emphasis on ethical practices among public procurement practitioners, transparency and accountability will remain critical in ensuring effective and efficient procurement operations. This paper examines the influence of transparency and accountability in enhancing regulatory compliance in public procurement. This study was quantitative in nature and utilised a quantitative analysis approach to analyse data from 202 public procurement practitioners in Dodoma, Tanzania. The study applied structural equation modelling to examine the relationship between transparency, accountability, and regulatory compliance in public procurement. The results indicate a positive and significant relationship between transparency and regulatory compliance (β = 0.148, p = 0.048). The study also reveals that accountability is a significant and positive factor that promotes regulatory compliance (β= 0.366, p < 0.001). The study’s findings offer valuable insights for public procurement practitioners to establish well-defined standards of practice concerning transparency and accountability in procurement operations, with the aim of improving regulatory compliance. The research contributes to the existing literature on enhancing procurement compliance in the public sector by exploring the role of transparency and accountability in procurement regulatory compliance in Tanzania.

    It's fine for them, but what about us? Exploring the role of supplier management practices on public buyer satisfaction
    (Elsevier BV, 2024) Changalima, Ismail A.
    Supplier management practices, such as supplier selection and evaluation, monitoring, and development, are multifaceted strategies aimed at enhancing supplier performance for the benefit of buyers. However, their role in explaining buyer satisfaction within the realm of public procurement is not well understood. The study addresses this gap by exploring the predicting role of supplier management practices on public buyer satisfaction. Data obtained through questionnaires from 179 public buyers in Tanzania and was analyzed by using partial least squares structural equation modeling (PLS-SEM) so as to test three main hypotheses. The results showed positive and significant relationships between all supplier management practices and buyer satisfaction. Notably, among these practices, supplier selection and evaluation emerged as the strongest predictor on explaining buyer satisfaction. This study offers valuable empirical evidence on the impact of supplier management practices on public buyer satisfaction. Public organizations (buyers) should consider effective implementation of supplier management practices by giving much attention to supplier selection and evaluation, monitoring and development as they are relevant for enhancing buyer satisfaction. The study holds significant implications for policy makers in public procurement undertakings, especially in Tanzania, where robust public procurement practices are essential for the country’s development.

    Unveiling the role of entrepreneurship education on green entrepreneurial intentions among business students: gender as a moderator
    (Informa UK Limited, 2024) Makuya, V; Changalima, Ismail A.
    The research investigates the impact of entrepreneurship education (EE) on green entrepreneurial intentions (GEI) among business students. Additionally, the study conducted a moderation analysis to examine whether gender influences the relationship between EE and GEI among female and male business students. Data were collected from 204 Tanzanian business students who had completed an entrepreneurship course as part of their major, using structured questionnaires. Quantitative data analysis and moderation effect testing were performed using PLS-SEM in SmartPLS 4. The findings reveal a significant positive relationship between EE and GEI. Moreover, gender was found to be significantly related to GEI, with males exhibiting a stronger effect compared to females. However, despite this, the study found that gender does not moderate the relationship between EE and GEI. This study offers unique insights into the influence of EE on GEI and the moderating effect of gender in the Tanzanian context. Furthermore, the study contributes to Sustainable Development Goal 4 by addressing the importance of enhancing education quality and ensuring inclusive and equitable learning opportunities for all individuals. The research also carries policy implications for promoting green business initiatives among future entrepreneurs. While the study provides valuable contributions, it is limited by its sample size, which solely consists of business students from Tanzania. Future research should consider expanding the sample to include students from various academic programs and diverse geographical locations to enhance the generalizability of the findings.
