Purpose
This study aims to examine the usefulness of trust in e-government to influence the use and success of e-government services within the context of the information system (IS) success model and public value theory.
Design/methodology/approach
The study proposed a conceptual model comprising 17 hypotheses tested using structural equation modelling-partial least squares. Data was collected through a structured questionnaire from 369 e-government users from Nigeria.
Findings
The results show that trust in e-government is directly influenced by all information quality, service quality and actual use. Also, trust in e-government predicts the public value of e-government, among other variables. Trust in e-government mediates the relationship between the quality dimensions and the public value of e-government. Also, the quality dimensions predict the actual use and user satisfaction with e-government. The most significant effect was established in the relationship between trust in e-government and the public value of e-government.
Research limitations/implications
This study used a targeted and small sample size compared to the teledensity of Nigeria, limiting analysis that might influence the relevance of the variables’ relationships. Other individual characteristics such as self-efficacy and access to information and communication technologies (ICT) and digital literacy were not included in the study.
Practical implications
It is expected that public service managers and ICT implementers would learn and take advantage of the system’s strengths and limitations and resolve expectations to enhance its value.
Originality/value
This study extended the DeLone and Mclean IS success model to incorporate public values as the net benefits of e-government. The public value of e-government was treated as a second-order construct.
This paper explored the successes and challenges of Information and Communications Technology (ICT) adoption in the combat against bureaucratic corruption in the Nigerian public service. This study adopted a qualitative approach via in-depth interviews for data collection and thematic analysis. Interviews were conducted within purposively sampled public officials with over ten years of experience in the public service. Two major themes were identified; successes and challenges encountered in the fight against bureaucratic corruption with the use of ICT. It is discovered in this paper that ICT has played a significant role in the combat against bureaucratic corruption by increasing the revenue of the government through the Integrated Personnel Payroll Information System (IPPIS) and Treasury Single Account (TSA) systems. However, challenges faced in this regard can be attributed to the infrastructural gap, shortage of ICT skilled personnel and resistance by the public officials. It is therefore recommended that for the little success to be sustainable, those challenges must be mitigated.
Different studies have evaluated the success of e-government in developed and developing countries. However, many of these studies rely on the economic and conventional approaches to evaluate e-government like other ICT projects. Also, they do not consider citizens’ access to ICT in their studies. This study, therefore, examines the moderating effect of citizens’ access to ICT on the performance of e-government within the context of IS Success Model and public value theory. The public value of e-government represents the net benefits of e-government. Data were collected from 369 experienced e-government users through a range of selected e-government services. The results show that citizens’ access to ICT positively and significantly moderates the relationship between actual use and the public value of e-government. This finding implies that access to ICT will drive more use of e-government and increase the value of e-government services. Also, the quality dimensions affect the actual use and user satisfaction with e-government. The most significant effect was established in the relationship between service quality and the actual use of e-government. In essence, this study emphasized the efficacy of ICT access as a stimulating effect on creating public value through increased citizens’ use of e-government for interacting with the government. Ultimately, it prompts the government to improve ICT access for the citizens to use more e-government services.
This study assessed the impact of ethical leadership on employee performance in the public sector using leader-member exchange as a mediator. Data for this quantitative study was gathered using a structured questionnaire administered to Nigerian federal public officials in some selected ministries. A conceptual model was drawn and put to the test using the PLS-SEM. Based on the results, all hypotheses were significant at p < 0.001. More importantly, ethical leadership positively and significantly impacts leader-member exchange and employee productivity. More so, leader-member exchange mediates the relationship between ethical leadership and employee performance. This study’s findings improve on earlier studies on ethical leadership and leader-member exchange relationships. Also, it suggests the importance of leaders’ moral behaviour and their relationship with subordinates in the workplace, by imbibing workplace ethics. This study has added to the continuing discussion on ethical leadership and its implications in the public sector in a developing nation like Nigeria.
