The effects of gross domestic product and energy consumption on carbon dioxide Emission in Uganda (1986-2018)

This study examines the effects of energy consumption and per capita gross domestic product on carbon dioxide emission which is a precursor for global warming due to its large scale impact on the environment. The effect of per capita gross domestic product and per capita energy consumption on carbon emission per capita in Uganda is not clearly known. This study fills the empirical gap for Uganda for 1986-2018. The study used Vector Error Correction techniques and the results suggest evidence of a long-run relationship between the variables at a 5% significance level using the Johansen cointegration test. The estimated elasticity of carbon dioxide emission per capita with respect to gross domestic product per capita is 1.856. The results for the existence and direction of Granger causality show a unidirectional causality running from gross domestic product per capita to carbon dioxide emission per capita and the environmental Kuznets curve hypothesis is supported. In addition, there is no causal link between energy consumption per capita and gross domestic product per capita, which supports the growth neutrality hypothesis. The overall results indicate that gross domestic product per capita has a positive effect on carbon dioxide emission in Uganda while energy consumption does not Granger cause carbon dioxide emission.
Nurturing innovative behaviour among knowledge workers : the role of social interaction mediated by human capital resources
(International Journal of Sociology and Social Policy, 2025-12-30) Kintu, Gerald Joseph; Kaberuka, Will; Mafabi, Samuel; Watundu, Susan; Bagoroza, Janet Kyogabiirwe; Kagaari, James
Purpose As the global economy transitions into a knowledge-based economy, labour demand is shifting from manual workers to knowledge workers whose cardinal role is to create innovative solutions. This has forced organizations to pursue alternative mechanisms that promote innovative behaviour among knowledge workers. This study examined the relationship between social interaction and innovative behaviour among knowledge workers, mediated by human capital resources. Design/methodology/approach The study used a cross-sectional research design. Data were collected from information and communication technology (ICT) professionals working in various companies in Uganda. The structural equation modelling technique using analysis of moment structures (AMOS) was adopted to carry out data analysis. Findings Study results have shown that the relationship between social interaction dimensions of coordination and communication with innovative behaviour is partially mediated by human capital resources. However, results showed that while mutual support enriches innovative behaviour, human capital resources do not mediate this relationship. Practical implications Organizations need to create workplace environments built on collective actions while harnessing the power of interactive learning that emerges from coordinated tasks and information sharing. This will create a platform that nurtures knowledge sharing and learning of skills collectively, which builds competencies for generating innovative ideas aligned to the business context. Originality/value While empirical research has concentrated on showing the direct relationship between social interaction and innovative behaviour, the current study investigates this relationship by examining the indirect effect of human capital resources.
