The Nigerian public sector is often characterized by low innovation, weak employee engagement, limited motivation, inadequate training, and administrative rigidity. In contrast, the private sector demonstrates higher performance through flexible management practices and continuous learning systems. This study examined the extent of cross-sector learning adoption in the Nigerian public sector and its effect on performance and employee engagement. Using a quantitative design, data from 393 respondents were analyzed with descriptive and inferential statistics. Findings showed a moderate level of cross-sector learning adoption (M = 3.47, SD = 0.52), indicating that such practices are present but not fully institutionalized. Administrative structure had a significant but weak positive relationship with cross-sector learning (r = .21, p < .05). Additionally, cross-sector learning was positively associated with performance and employee engagement (r = .22, p < .05). The study recommends formalizing cross-sector learning, restructuring administrative systems, and strengthening inter-sectoral collaboration.

: The adoption of management control tools depends on several factors, as explained in the literature on the relationship between consulting firms and businesses: the choice of the designer; factors influencing adoption in general; the designer’s assumptions regarding the results and expectations of the business leader; and the impact of the designer’s profile. However, studies examining the relationship between the designer’s profile and the adoption of management control tools do not sufficiently account for the factors that influence these tools—namely, the objectives assigned to them or the relationship with the user. This study, whose primary objective is to understand how a manager’s profile contributes to the adoption of management control tools by executives of service-sector SMEs, aims to address this limitation. The theoretical framework used in this study is actor-network theory. It posits that actors construct networks that combine technical and social elements, all of which are simultaneously shaped and formed within these networks. This study adopts an interpretive and constructivist approach, placing the designer at the center of the process of adopting management control tools.

This study examines the effects of government effectiveness and public investment on economic performance in Sub-Saharan Africa (SSA). Panel data from 22 selected countries covering the period 2007–2024 were utilized for the analysis. GDP per capita growth served as the proxy for economic performance, while government effectiveness and public investment were the main explanatory variables. Inflation, exchange rate, and trade openness were included as control variables. Data were obtained from the World Development Indicators (WDI) and Worldwide Governance Indicators (WGI) databases. Descriptive statistics, panel unit root tests, the Pedroni cointegration test, pooled ordinary least squares, fixed effects, and random effects estimation techniques were employed for the analysis. The Hausman test identified the fixed effects model as the preferred estimator, while White cross-section robust standard errors were used to test the robustness of the results. The findings revealed that government effectiveness exerts a positive and significant influence on economic performance, while trade openness also contributes positively to economic growth in the region. However, public investment, inflation, and exchange rate were found to have insignificant effects during the study period. The study concludes that effective governance remains a critical factor in improving economic performance in Sub-Saharan Africa. Therefore, policies aimed at strengthening institutional quality, enhancing public sector efficiency, and promoting greater integration into international trade are necessary for achieving sustainable economic growth in the region.
