This paper provides evidence that the banking sector reforms of 2004 and 2009 enhanced prudential performance of the banking industry and financial system stability in Nigeria.

This study uses regression analysis with regime shift to confirm results from tests of two means and variances model to examine the effectiveness of banking sector reforms in Nigeria.

Evidence from the regression model agrees with findings from the test of means model (not controlling for trend effects) that capital to assets ratio rose while non-performing loan ratio declined after the reforms, and that capital to earning assets ratio rose when trend effects were accounted for. Both the regression model and the tests of means model controlling for trend effects show that return on asset, return on equity and return on earning assets ratios declined after the reforms.

This paper evaluated the effectiveness of banking sector reforms in Nigeria using models that avoid weaknesses that besieged many previous studies. It however used data covering 1983–2020 period, due to data availability. A larger scope of data may improve the results, and future research may re-examine this theme as more data become available. Furthermore, banking stability issues could be examined using specialised techniques such as the generalised autoregressive conditional heteroscedasticity model and related family.

These results suggest that the reforms led to improvement in the sector’s resilience (risks-absorbing capacity) and asset quality, and that profitability had not been the primary focus of the reforms.

The authors recommend that regulatory and supervisory authorities in Nigeria continue to implement and improve on banking sector reforms for a more resilient and functional banking system. As a contribution to social research, this study shows that studies on policy evaluation should be located within appropriate theoretical framework: the theory of change. It shows that an appropriate use of attribution analysis and contribution analysis within this theoretical framework engenders robust analysis and results. Otherwise, the analytical findings would be erroneous and policy advice misguided.

The statistical significance of our findings establishes that the banking sector reforms in Nigeria have been effective in promoting financial system stability in Nigeria. By deploying both the test of means with and without trend effects (an attribution analysis) and the multivariate regression analysis with regulatory shift (a contribution analysis), and relying more on the later for its superiority, this study contributes to the body of knowledge in that, it not only determined the true effects of banking sector reforms in Nigeria for appropriate policy guidance but also demonstrated that, in research, an inappropriate methodology produces results that may diverge from the more accurate ones that were derived from the correct methodology.

Sustainable supply chain management (SSCM) practices and green entrepreneurial preference (GEP) have gained increasing attention from academicians; however, their impacts on business' competitive performance (BCP) post-coronavirus disease of 2019 (COVID-19) remain unclear. Although SSCM is vital for supporting BCP, the previous publications indicate the absence of significant relationships among GEP, SSCM and BCP. This study tries to fill this literature gap by investigating if GEP and SSCM can shape BCP. This study also suggests the moderation effect of digital innovations such as artificial intelligence and big data analytics (AIBD) on those relationships from a COVID-19 viewpoint.

Data were collected from 245 Halal food firms in Yemen, and the research framework was assessed using structural equation modeling (SEM).

The empirical findings show that there are significant impacts of GEP on SSCM and subsequently on BCP. The findings also reveal that SSCM practice mediates GEP-BCP link. Besides, digital innovations such as AIBD positively moderate the link of GEP-SSCM.

This study is the first attempt that advises Halal food firms to formally adopt GEP, SSCM and digital innovations to boost BCP, especially in uncertain times like post-COVID-19. Unlike earlier studies that observe SSCM usage as a direct predictor of firm performance, this study delivers an innovative insight that digital innovations can assist in GEP and SSCM incorporation in the in-house operations of the firms post-COVID-19.

The purpose of this paper is to examine the relationships between quality education and human resource management practices of faculty supervisor’s support, job autonomy and working condition in the private universities. Specifically, how does the working atmosphere in the private universities in Bangladesh play a mediating role in the links between faculty supervisory support and job autonomy toward excelling quality education?

To answer this question, a theoretical framework using the strategic contingency theory as its basis was established. Data (n = 515) were analyzed using structural equation modeling.

The findings of the study indicate that faculty supervisor’s support and working condition have significant positive relations with quality education and the working condition has an important mediating role in the links between supervisor’s support, job autonomy and quality education in the private universities in Bangladesh.

First, the study used faculty as respondents from only 19 private universities in Bangladesh where more than 100 universities are in active operation at present. Second, the study included only top-ranking private universities and ignored other low-grade local private universities ranked by the university grant commission and they should be included in the study. Third, this study did not include public universities in the survey. Fourth, only two antecedents to the working environment toward quality education were included. Finally, this study collected data only from the faculty of the school of business and economics for examining their opinion.

From an academic and practical perspective, as a cumulative body of study on the relationship between different HRM practices and quality education, this paper will be better able to advise concerned authorities of higher education intuitions on the elements they need to address to ensure quality teaching and learning in their institutes.

Several factors that directly and indirectly influence quality education through pleasant working environments appear to the surface. Thus, to create a vital working condition in private universities, academic leaders or authorities should be aware to make some improvements.

The study reveals a paramount finding that can help academicians and authorities of private higher education institutes.
