Credit Risk Management, Institutional Quality, and Financial Performance of Commercial Banks in Sub-Saharan Africa
Full text linkPurpose
This study examines the relationship between risk management and the financial performance of commercial banks in Sub-Saharan Africa, with particular emphasis on credit risk indicators and institutional quality.
Methodology
The study adopts an ex post facto research design. It uses secondary data from audited annual reports and financial statements of publicly listed commercial banks in Sub-Saharan Africa for the period 2018–2023. A two-step Generalized Method of Moments (GMM) estimator is employed to analyze the panel data and address potential endogeneity concerns.
Findings
The empirical findings reveal that the non-performing loans ratio exerts a statistically significant effect on bank financial performance. While the ratio of total loans and advances to total deposits shows a positive but statistically insignificant impact on profitability, changes in this ratio significantly influence bank profitability. Moreover, institutional quality is found to have a negative, statistically significant relationship with the return on equity (ROE) of commercial banks in Sub-Saharan Africa.
Conclusion
The results indicate that credit risk management and institutional quality play a critical role in shaping banks' financial performance in Sub-Saharan Africa. The study recommends that banks strengthen credit appraisal and risk monitoring mechanisms and ensure strict regulatory compliance to mitigate loan default risks. Additionally, policymakers are encouraged to enhance supervisory and regulatory frameworks to promote sustainable, resilient banking operations across the region
Remittances, Financial Technology and Financial Inclusion in Nigeria
Full text linkPurpose
This study examines the influence of remittances and financial technology on financial inclusion in Nigeria over the period 1990–2024.
Methodology
The study employs the Autoregressive Distributed Lag (ARDL) modelling framework to estimate short- and long-run relationships among financial inclusion, remittances, and financial technology adoption. Annual time-series data were obtained from the World Bank’s World Development Indicators (WDI) and the International Monetary Fund (IMF). Unit root tests and the ARDL bounds testing approach were applied to establish the existence of a long-run equilibrium relationship among the variables.
Findings
The empirical results indicate that remittances and financial technology exert a statistically significant positive effect on financial inclusion in the short run, suggesting that diaspora inflows and digital technologies act as immediate facilitators of access to financial services. However, the long-run effects of remittances and financial technology are not statistically significant, indicating that these drivers are insufficient to sustain financial inclusion without complementary institutional and infrastructural support. The findings further reveal that weak regulatory frameworks, inadequate digital infrastructure, and low levels of financial literacy constrain the long-term effectiveness of remittances and financial technology in promoting financial inclusion in Nigeria.
Conclusion
The results imply that improvements in financial inclusion in Nigeria are largely policy-driven and short-term rather than structural. To transform short-run gains into sustainable financial inclusion, stronger institutional frameworks, improved regulatory oversight, expanded digital infrastructure, and enhanced financial literacy are required.
The study contributes to the literature by providing long- and short-run evidence on the roles of remittances and financial technology in financial inclusion in a developing economy context, highlighting the importance of institutional and infrastructural factors in sustaining inclusive financial development
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
