The management of digital resources has become a critical function of university libraries in the digital age. However, Library Management Systems (LMS) plays a vital role in facilitating the organization, access, and preservation of these resources. The main objective of the study is to identify the types of library management systems adopted for digital resource management in university libraries in South-west, Nigeria. Resource-Based View (RBV) Theory was the theory adopted. Convergent parallel Mixed Method design was employed. The population of the study consisted of 354 librarians and 7 system analysts in selected university libraries using total enumeration techniques which gives a total of 361 respondents out of which 7 e-librarians were interviewed. Questionnaire and interview form are the research instruments for data collection and was validated using face and content validity with the help of two research experts. Reliability test was done by using Cronbach's Alpha method with an average reliability coefficient of 0.74. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were transcribed using TurboScribe software and analyzed thematically. Findings revealed that KOHA and Dspace are the major LMS adopted. Librarians used LMS to a great extent (x ̅=3.27). Results showed that technical know-how, user friendliness and ease of use jointly have a significant influence on digital resource management practices (F= 18.234, p< 0.05). The study concludes that library management systems applications influence digital resource management. The study recommends continuous capacity building for librarians and e-librarians, particularly in system configuration, integration, and troubleshooting.

Modeling the compressible flow field of an impulsively started circular cylinder with refined potential flow theory

Understanding compressible flows over bluff bodies, such as circular cylinders, is critical for applications in aerospace engineering, space exploration, and astrophysics. However, the complexity of viscous and unsteady flows, compounded by compressibility effects, remains a challenge for experimental and computational methods. This study explores the compressible flow field of an impulsively started circular cylinder using Refined Potential Flow Theory (RPT), an analytical model that extends classical potential flow theory to include compressibility effects. The governing equations, boundary conditions, and refined stream function are developed to capture the density, velocity, and pressure fields in subsonic and transonic regimes. The results demonstrate that compressibility marginally increases vortex enstrophy at low Reynolds numbers, while its influence on wake flow stability diminishes at higher values. The study reveals that compressibility suppresses shear layer instability, reduces wake velocity deficits, and introduces smaller-scale structures that disrupt the inertial range of turbulence in the low subsonic regime. At higher Mach numbers (M∞≥0.6), local supersonic pockets and shock waves emerge, forming complex λ-shock systems and bow shocks. The predictions of the Strouhal number from RPT show marginal changes for 0.2≤M∞≤0.5, consistent with experimental and computational trends. Although RPT aligns with existing methods to capture key flow features, discrepancies in wake stability and recirculation zone dimensions highlight areas for further refinement. This research underscores the potential of RPT in developing optimization tools that complement experimental and numerical studies, offering valuable insights into compressible flow physics for engineering applications in high-altitude flight and space exploration.

Business Cycle Synchronisation and Regional Migration: Testing the OCA Criteria in the West African Region
(Springer, 2024-12-07) Sodiq Olaiwola JIMOH; Chua Soo Yean
The West African region is on the verge of forming a monetary union. Many studies have examined the feasibility of monetary unions using criteria such as trade and financial integrations. However, labour migration which is one of the criteria has been neglected in previous studies. This study filled the gap by using Abel and Cohen's (Bilateral international migration flow estimates for 200 countries 6(1):1–13, 2019) data between 1996–2019 to examine the impact of migration flows on business cycle synchronisation using the IV-2SLS technique in the West African region. The study reveals that migration flow, specialisation of industry, and financial integrations spur business cycle synchronisation, while regional trade integration does not significantly impact business cycle synchronisation. However, the interactive terms of trade integrations and migration flow positively influenced business cycle synchronisation in the region. These findings suggest a likelihood of optimum currency area in the West African region.

Consumerism Activities and Brand Equity: An Empirical Analysis of Selected Fast-Moving Consumer Goods (FMCG) Manufacturing Companies in Nigeria
(2026-08-01) Adebayo Adeyemi Abdulwasiu; Ajayi, E. O; Olowookere, M. T.
This study examined the effect of Consumerism Activities and Brand Equity: An empirical Analysis in Nigerian fast-moving consumer goods sector with Unilever Nigerian Group of companies as a case study. Survey design was used for the study as data were collected using questionnaires administered on a sample of two hundred and fifty-nine questionnaires (259) received from respondents. The data analysis for the study was undertaken through PLS-SEM. Accordingly, the findings of the study revealed perceived Consumer Right Awareness positively influence the brand loyalty of the consumers of Unilever Group of companies with beta (β = 0.616), t-statistic (t = 17.813) and p value (p = 0.000), while regulatory compliance also has positive and significant relationship with product quality (β = 0.466), t statistics (t = 10.081) and p value (p = 0.000). The study concluded that empowering consumers and adhering to regulations serve as strategic catalysts that transform transparency and legal standards into competitive assets for loyalty and quality. By leveraging these benchmarks as internal controls, firms minimize operational errors while fostering secure, long-term consumer commitment. The study recommends that Unilever should prioritize consumer education and transparent rights policies fosters long-term brand retention and market growth by transforming informed customers into strategic assets. Similarly, integrating regulatory compliance into early production stages secures product reliability and elevates overall market performance through standardized quality excellence.

Marketing Circular Economy Practices and Consumer Perception of Recycled Products from Nigerian Manufacturers: Extended Triple Bottom Line Approach
(Al-Zaytoonah University Journal of Business (ZJJB), Al-Zaytoonah University of Jordan, 2026-08-02) Adebayo Adeyemi Abdulwasiu
The research focused on analyzing the impact of marketing circular economy practices and recycled products from Nigerian FMCG producers. Survey was the research design for the study as questionnaire was used in gathering data from the respondents and a total of one hundred and seventynine copies of questionnaires (179) were inputted for analysis. Data analysis was conducted using PLSSEM for the study. Accordingly, the findings of the study showed that Eco-Branding Appeal positively affect Perceived Environmental Benefit, but not significantly with positive path coefficient (β = 0.073), with statistical insignificant effect (t = 1.032, p = 0.302), while Reverse Logistic Ease was positively significant on Perceived Environmental Benefit (β = 0.354, t = 4.799, p < 0.001) which indicates that customers have an easier time identifying the environmental benefits of recycled products when they have access to simple recycling and returning procedures. The study concluded that although green branding affects consumers’ perception of the convenience of reverse logistics, but in practical term, it does not convince them of actual environmental benefits as consumers are naturally skeptical of sustainability claims made through marketing, and perceive functional sustainability infrastructure as proof of organizational integrity. The research further recommended that among others that the company should combine eco-branding with transparency of operations, by explaining how return and recycling policies are turned into concrete environmental results, closing the gap between brand love and perceived benefit
