Abstract

Electric vehicles are being introduced as a sustainable innovative solution, aimed at eliminating the negative environmental effects by having the ability to reduce carbon emissions, air pollution and fossil fuel dependency. It is therefore important for management, marketers and government to find innovative ways to promote and increase the adoption rate of these vehicles. This paper aims to make use of the theory of consumption values to predict the purchase intention for plug-in hybrid electric vehicles (PHEVs) in Gauteng, South Africa. Using structured questionnaire and convenience sampling, data was collected from 286 respondents. Online data collection was used due to the Coronavirus pandemic restrictions, which limited the researchers’ abilities to explain items in the questionnaire. A partial least squares structural equation modelling was performed to test the proposed hypotheses. Results indicate that functional, social, emotional and conditional values are positively related to customers’ purchase intention of PHEVs, while the epistemic value is not positively related. This study will provide useful information to electric vehicle manufacturers, car dealerships, marketing managers and the government in developing strategies aimed at encouraging the adoption of PHEVs.

Abstract

This study was conducted in South Africa to identify and understand the perceptions and attitudes of young adults towards blood stem cell donation. Despite a global rise in demand for blood stem cells, less than 1% of South Africans are registered donors, indicating a severe shortage. A cross-sectional quantitative survey was carried out among 276 young adults aged 18 to 35 years across various provinces. Data were collected on attitudes, subjective norms, perceived behavioural control, and intention towards blood stem cell donation. The data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) with bootstrapping (5000 resamples). The results show that all three antecedents of the Theory of Planned Behaviour significantly influenced intention: attitude (β = 0.196, p < .001), subjective norm (β = 0.476, p < .001), and perceived behavioural control (β = 0.325, p < .001), explaining 41.2% of the variance in intention (R² = 0.412). These findings highlight that young adults who hold positive attitudes, feel social encouragement, and perceive control over the donation process are more likely to express willingness to donate. The study underscores the critical role of social marketing and awareness campaigns in enhancing donor participation and mitigating the blood stem cell shortage in South Africa.
