This study evaluated the impact of supply chain optimization on the financial performance of manufacturing firms in South-East Nigeria. A descriptive survey research design was adopted, and data were collected from a sample of 147 respondents drawn from four selected manufacturing firms using a structured questionnaire. The data were analyzed using descriptive statistics and multiple regression analysis. The findings revealed that inventory management (β = 0.432, p < 0.05), logistics and distribution efficiency (β = 0.385, p < 0.05), and supply chain technology adoption (β = 0.298, p < 0.05) all have significant positive effects on financial performance, with a combined explanatory power (R²) of 0.68. The study concluded that effective supply chain optimization enhances profitability and operational efficiency. It was therefore recommended that manufacturing firms adopt efficient inventory systems, improve logistics operations, and invest in modern supply chain technologies to achieve sustainable financial growth.

Background: Hyperglycemia, a key risk factor for Type 2 Diabetes Mellitus (T2DM), has become a significant health concern globally, especially in urbanizing areas. Taxi drivers, with their sedentary work environment, long hours, and irregular eating habits, may be at higher risk for metabolic disorders such as hyperglycemia. This study aimed to evaluate the prevalence of hyperglycemia and identify associated risk factors among taxi drivers in Agblezaa-Teshie, Greater Accra, Ghana. Methods: A cross-sectional study was conducted among 133 active taxi drivers in the Teshie Agblezaa area. Fasting blood glucose levels were measured, and sociodemographic, lifestyle, and occupational data were collected using structured questionnaires. Results: The prevalence of hyperglycemia was found to be 24.1%, with older drivers (aged 50- 59 years) and those working longer hours (9-12 hours daily) exhibiting higher rates. Lifestyle factors such as sedentary behavior, poor dietary habits, work-related stress, and low physical activity were strongly associated with hyperglycemia. While the majority of drivers were aware of general health risks related to hyperglycemia, their knowledge of specific symptoms and prevention strategies was limited. Significant barriers to healthcare access included financial constraints, time limitations, and lack of health insurance. Conclusion: The study highlights a substantial burden of hyperglycemia among taxi drivers in Agblezaa-Teshie, driven by sedentary work, poor lifestyle choices, and limited healthcare access. Targeted health interventions, including regular glucose screenings, health education, and improved healthcare access, are urgently needed to address this public health concern.

This study examined the effect of supply chain optimization on the operational efficiency of manufacturing firms in South-East Nigeria, with specific focus on inventory management, logistics and distribution, and supplier relationship management. The study adopted a survey research design, and data were collected through structured questionnaires administered to 109 employees of selected firms, out of which 102 responses were valid for analysis. Data were analyzed using descriptive statistics and regression analysis. The results revealed that inventory management optimization had a significant positive effect on operational efficiency (β = 0.322, p = 0.001), logistics and distribution optimization also showed a significant effect (β = 0.287, p = 0.001), while supplier relationship management had the strongest influence (β = 0.341, p = 0.000). The study concluded that effective supply chain optimization significantly improves operational efficiency by reducing delays, minimizing costs, and enhancing productivity. It was therefore recommended that manufacturing firms strengthen supplier relationships, improve inventory systems, and adopt efficient logistics strategies to achieve better operational performance.

Profitability remains a critical concern for deposit money banks in Nigeria due to increasing exposure to financial risks and regulatory pressures. This study examined the effect of risk management on the profitability of quoted deposit money banks in Nigeria, with specific focus on credit risk, liquidity risk, and operational risk. The study employed panel data covering 2015-2024 firms and Return on Assets (ROA) was used as a proxy for profitability. Credit risk, liquidity risk, and operational risk served as the explanatory variables. Descriptive statistics, correlation analysis, and panel regression techniques were applied in the analysis. Diagnostic tests, including the Hausman specification test, Variance Inflation Factor (VIF), Breusch–Pagan heteroskedasticity test, and normality tests, were conducted to ensure robustness of the results. The Hausman test supported the use of the Random Effects Model, while the presence of heteroskedasticity necessitated the use of heteroskedasticity-robust standard errors. The findings revealed that liquidity risk has a statistically significant negative effect on profitability, indicating that inefficient liquidity management reduces banks’ earning capacity. Credit risk and operational risk were found to have statistically insignificant effects on profitability within the study period. The study concludes that effective liquidity management is central to enhancing profitability of quoted deposit money banks in Nigeria. It recommends strengthening liquidity monitoring frameworks, improving asset–liability management strategies, and sustaining prudent risk management practices to ensure financial stability and sustainable bank performance.
