Purpose: Entrepreneurship is a vital source of job creation and a key driver in promoting economic growth. The Malaysian government encourages higher educational institutions (HEIs) to develop more competitive and innovative graduates for the economy so that Malaysia achieves high-income nation status by 2025. This study aims to investigate the mediating role of attitude toward entrepreneurship (ATE) in the relationship between key psychological factors, that is, subjective norm (SN), perceived behavior control (PBC), big-five (BF) personality traits, entrepreneurial motivation (EM) and educational factors (EFs) with entrepreneurial intention (EI) among Malaysian university students. Design/methodology/approach: This study used a quantitative design based on a positivist approach. The adopted questionnaire was used as the survey instrument. The primary data were collected from a sample of 251 final-year students in the management field who were enrolled in research-intensive Malaysian universities. Data were analyzed through the structural equation modeling (SEM) technique using AMOS 24 software. Findings: Findings confirmed that the BF personality traits, EM, PBC, SN, ATE and EFs were positively related to EI. Furthermore, ATE mediated the relationship between BF personality traits, EM, PBC, SN, EF, and EI among Malaysian university students. Research limitations/implications: This research provides critical insights into the key antecedents, for example, psychological and EFs, in explaining the EI of university students and future graduates. However, results can only be generalized to research-intensive Malaysian universities. Originality/value: This study investigated the relationship between psychological factors, that is, BF personality traits, EM, PBC, SN and EFs in predicting EI of Malaysian university students. ATE mediated the relationship between BF personality traits, EM, PBC, SN, EF and EI among these students.

Purpose: Organizational citizenship behavior for the environment (OCBE) is vital for manufacturing firms' ability to improve their triple bottom line (TBL) performance. This study's objective was to examine the direct relationship between three OCBE key dimensions, i.e. eco-initiatives (EIs), eco-civic-initiatives and eco-helping (EH) and TBL performance, i.e. economic (ECOP), social (SOP) and environmental (ENP). Design/methodology/approach: The quantitative design was used based on the positivist approach. A sample of 350 manufacturing firms was targeted using random probability sampling via a survey questionnaire. The data were analyzed through the structural equation modeling (SEM) technique employing AMOS 24 software. Findings: Research findings confirmed a significant direct positive relationship between components of OCBE, i.e. EIs, eco-civic- initiatives and EH and TBL performance within ISO14001-certified Malaysian manufacturing firms. Research limitations/implications: This research presents vital implications for both managers and organizations. The findings revealed that the three OCBE key dimensions, i.e. (EIs, eco-civic-initiatives and EH) are essential for enhancing TBL performance (ECOP, SOP and ENP), respectively. Manufacturing firms should modify the traditional OCB toward pro-environmental OCBE to improve TBL performance. Originality/value: This research focuses on the impact of OCBE key types, i.e. EIs, eco-civic-initiatives and EH on TBL performance (ECOP, ENP and SOP) dimensions among ISO14001-certified Malaysian manufacturing firms.
