This study ascertains whether three positive organizational behaviour capacities (optimism, self-efficacy and self-monitoring) predict attitude towards organizational change. Design of this study was cross-sectional, and data were collected with self-report measure. One hundred sixty-nine employees were drawn from 21 organizations in Delta State, Nigeria. The participants were made of 108 (64%) females and 61 (36%) males, with the mean age of 40.21 years (SD, 9.13). Simple regression analysis revealed that optimism, self-efficacy, and self-monitoring, positively and significantly predicted attitude towards organizational change. While multiple regression analysis revealed that only self-efficacy positively and significantly contributed to attitude towards organizational change. It was concluded that the predictors influence employees' attitude towards organizational change with self-efficacy contributing the highest influence to organizational change attitude. It was recommended that for successful employees change acceptance, optimism, self-efficacy and selfmonitoring should be structured into policies and strategies for organizational implementation.

The need to fully exploit human resources for competitive advantage has brought spirituality into the work setting. The study set to examine the predictive relationship workplace spirituality has with perceived organizational support and job performance. The assessment is premised on Rego and Cunha's five-workplace spirituality dimension model. This study adopted a correlational design with a self-administered questionnaire of 118 university administrative employees at a university. The research hypotheses were tested with regression analysis. Results show that composite workplace spirituality correlates positively and significantly with perceived organizational support and job performance. However, only a few of the dimensions show positive and significant results. This study shows that enhancing workplace spirituality improves employees perceived organizational support and job performance. Therefore, it is recommended that human resource management practitioners recognize the influence of workplace spirituality in the effective functioning of the organization.

A fierce competitive workplace climate compels employees to work under pressure, hence, to perform requires individual's innovate positive psychological resources. This paper sets out to examine the predictive relationship between psychological capital (PsyCap) and innovative work behaviour (IWB) among public employees, and the role of task autonomy in the relationship. A cross-sectional survey design was conducted, and 125 employees from public hospitals participated in the study. The study used a questionnaire focussing on measures of PsyCap, IWB, task autonomy as well as questions on demographic characteristics. The research hypothesis was tested using regression analysis. Multiple regression analysis showed self-efficacy ( = 0.25, p < 0.01) and optimism ( = 0.14, p > 0.05) positively and significantly predict IWB. The investigation implicitly tested and confirmed the applicability of certain elements in Bandura's social cognitive theory and Vroom's expectancy theory from the examination of PsyCap-IWB link.

This study ascertains the predictive relationship that sustainable organisational practices have with organisational effectiveness and the mediating role of organisational identification and organisation-based self-esteem in this relationship. One-hundred and forty-five participants (62 males and 83 females) were sampled from 31 privately-owned organisations in Delta State, Nigeria. Regression analysis revealed that sustainable organisational practices positively and significantly predict organisational effectiveness, β = 0.42, p < 0.001, and that organisational identification and organisation-based self-esteem mediate the relationship. It was recommended that privately-owned organisations intensively implement sustainable organisational practices for organisational effectiveness, organisational identification and organisation-based self-esteem.
