Historically, state-owned commercial banks (SOCBs) in Sierra Leone have shown relatively high performance than State-Owned Utility Companies (SOUCs) in the country. While several issues may have contributed to such low performance by SOUCs, this study aims to explore whether and how (if any) compliance with corporate governance practices (based on CACG Code) varies between the high-performing SOCBs and low-performing SOUCs, and whether this variation of compliance causes performance differences. A cross-sectional research design with quantitative approach was adopted. A survey was conducted in two SOCBs and two SOUCs in 2025. Apart from questions on respondent and organizational backgrounds, a self-completion questionnaire comprising 66 questions (governance – 39 & performance -27) was successfully completed and returned by 144 participants. Further, a checklist of 19 items was constructed based on the Acts of Parliament and scored against the CACG Code provisions by the researcher. Using SPSS and Excel Programs, data was analyzed using descriptive (percentages, and mean percentages) and inferential (Pearson’s correlation, and simple linear regression) statistics. The Overall Compliance Index of SOCBs is 68% while SOUCs has an index of 45%. The correlation coefficients (r = 0.996 and r = 0.998) indicate a very strong positive linear relationship between governance and performance. Also, the regression results (adjusted r2 = 0.988, df = 3; p < 0.01) indicate a strong association between corporate governance and firm performance. The study shows that SOUCs’ rate of corporate governance compliance is weaker than SOCBs in most criteria set by the CACG Code, which might have caused low financial performance by SOUCs (40%) and high financial performance by SOCBs (64%). The findings of the study have practical and policy related implications to improve the performance of SOUCs in Sierra Leone.

Chest radiography remains the cornerstone of diagnostic imaging globally, functioning as a primary triage and diagnostic tool for a diverse array of cardiopulmonary pathologies, particularly tuberculosis and pneumonia. In resource-constrained environments like Cameroon, healthcare systems exhibit an extreme reliance on chest radiography; however, the structural frameworks necessary to optimize image quality and minimize patient radiation dose are frequently inadequate. This narrative review evaluates the clinical relevance and practical implementation of stringent European image quality guidelines specifically the EUR 16260 anatomical criteria and the European Union Directive 2013/59/Euratom within the Cameroonian context. The analysis synthesizes current methods of image quality assessment, encompassing visual grading analysis, reject and repeat audits, standardized exposure indices (IEC 62494-1), and the integration of artificial intelligence tools such as CAD4TB. Translating European standards to Cameroon encounters profound structural barriers, driven primarily by a critical shortage of radiological personnel, with a radiologist density of approximately two per million inhabitants compared to the European average of 127 per million. Additional friction points include the unmonitored transition from analogue to digital radiography, the inconsistent application of Diagnostic Reference Levels (DRLs), and the limited enforcement capacity of the National Radiation Protection Agency (ANRP). Despite these systemic hurdles, strategic opportunities exist to elevate diagnostic standards. Expanding teleradiology networks to support remote facilities, implementing low-cost quality assurance audits, and leveraging artificial intelligence for automated image assessment offer viable solutions to bridge the quality gap. The establishment of localized DRLs and the prioritized training of radiographers and medical physics experts stand as essential prerequisites for achieving sustainable diagnostic excellence and radiation safety in Cameroon. Establishing routine diagnostic reference levels for standard procedures is a universally recommended practice for adhering strictly to the ALARA principle.

This study examined the impact of Government bond on economic growth in Nigeria for the period between 1999 and 2024. An ex-post-facto research design was adopted and the study was based on the theoretical framework of the Keynesian theory of public finance. Time series data on values of amount of government bonds issued (GBA), Number of government bond issues (GBN), average government bonds issued maturity period (GBM) and average government bonds yield (GBY) as independent variables and Gross Domestic Product Growth Rate (GDPr) as dependent variable were collected from publications of CBN, NBS and World Banks. The data collected were subjected to both pre-estimation and post estimation tests for variables trend characteristics, descriptive statistics, unit root, co-integration, causality, serial correlation and normality. Secondly, a VECM technique of estimation was employed to determine the variable coefficients and T-statistic test of hypotheses was employed to determine their significance. Generally, the study found a significant relationship between the government bond variables and Nigeria’s economic growth. On the individual variables findings, while amount of government bonds issued (GBA), Number of government bond issues (GBN) and Average bonds issued maturity period (GBM) have positive and significant impact, average government bonds yield (GBY) has negative but insignificant impact on economic growth during the period under review in Nigeria. While a unit change is GBA, GBN and GBM increases GDPr by 1%, 4.32% and 39.05% respectively, a unit increase in GBY decreases GDPr by 22.57%. The study recommended in addition to others that the Nigerian government should diversify and deepen its bond market by introducing various bond types and extending maturity profiles. This can attract a broader investor base, reduce borrowing costs, and ensure that the government can finance infrastructure projects more effectively over the long term, ultimately fostering more stable economic growth.

The study investigated the impacted of external debt and capital formation on economic growth in Nigeria (1980-2025). The Autoregressive Distributed Lag (ARDL) modelling approach was used because ARDL is an appropriate modelling approach for variables that are integrated of mixed orders, I(0) and I(1). The Augmented Dickey-Fuller (ADF) unit root test and the ARDL Bounds test for cointegration were performed as preliminary analyses. The ARDL Bounds test confirms the existence of a long run relationship between the variables since the value of F-statistic (8.543949) is above both the lower and upper bounds at all the levels of significance (1%, 2.5%, 5% and 10%). The short-run error correction model suggested that the error correction term is negative and statistically significant (-0.318810, p < 0.01) which means that about 31.9% of short-run disequilibrium is corrected toward LR equilibrium per year. The results also indicated that the external debt had a negative effect on economic growth while the capital formation had a positive effect on the long-run economic growth. While inflation had both positive and negative short-run effects, the short-run effects of exchange rate and government expenditure were not statistically significant. The post-estimation diagnostic tests showed the absence of any serial correlation, heteroscedasticity and normal distribution of the residuals, thus the estimated ARDL model was robust and reliable. The study comes to the conclusion that while external borrowing is still a vital source of development financing, its impact is limited if it is not being used in a productive way or the debt management is unsustainable, whereas the quest to build more capital is still a key ingredient to a sustained economic growth in Nigeria. The study suggests that the government should implement prudent debt management of its external debt by investing the borrowed money in productive sectors with high return to the economy and improving its debt sustainability assessment.
