Purpose The purpose of this paper is to examine the mediating role of goal clarity in the relationship between leadership styles and project success. The paper draws on full-range leadership theory, and contextualizes leadership styles such as transformational leadership style, and transactional leadership style (active management by exception, and contingent reward) to temporary project environment. Design/methodology/approach Data are collected (in year 2017) from 248 individuals working in ten large project-based organizations from different sectors, each having multiple units in Pakistan. Respondents comprise functional managers and individuals (who have lead or worked on projects), as well as dedicated project managers. Findings Goal clarity partially mediates the relationship between transformational leadership style and project success. However, in case of the transactional leadership style, there is no mediation as transactional leadership style is not associated with goal clarity. Furthermore, contingent reward is positively associated to project success, while active management by exception is negatively associated to project success. Originality/value Research suggests that the underlying mechanisms of the relationship between leadership styles (transactional and transformational) and project success are less clear and need to be further explored. This study contributes to literature by answering such calls, and examines possible underlying mechanisms (i.e. goal clarity) in the relationship between leadership styles and project success.

PurposeThe purpose of this study was to examine the impacts of consumers’ motivations (i.e. remuneration, social, and empowerment) on online purchase intentions mediated through trust towards retailers present on social media.Design/methodology/approachData were collected from consumers residing in the three metropolitan cities of Pakistan, and the research model was tested using the covariance-based structural equation modelling in Amos.FindingsThe results showed that remuneration and social motivations positively influenced consumers’ online purchase intentions directly, as well as indirectly mediated through trust. However, trust fully mediated the relationship between empowerment motivation and consumers’ online purchase intentions.Originality/valueThe existing literature reveals that only a handful of studies have endeavoured to understand consumers’ trust in the context of social media marketing, and the literature in this field is not matured yet. The novelty of this research lies in its contribution to understanding the impacts of consumers’ motives (i.e. remuneration, social, and empowerment) on trust towards retailers present on social media, which have not been explored before. In addition, it examines trust towards retailers present on social media as an underlying mechanism that affects the relationships between consumers’ motives and online purchase intentions.

The study aimed at exploring the mediating effects of job satisfaction on role stressors namely, role overload and role conflict as sources of stress, on one hand, and affective commitment, on the other. Using a self-administered questionnaire, 151 branch managers of private sector commercial banks in Pakistan were randomly selected and surveyed to examine the mediating role of job satisfaction. Results revealed that role overload and role conflict directly and negatively influence job satisfaction. It was also found that role overload and role conflict directly and negatively influence affective commitment. The causal steps method along with correlation tests revealed that job satisfaction partially mediated the effects of role overload and role conflict on affective commitment. Implications, limitations, and future lines of research are also discussed in the paper.

Organizations need to be innovative for their long-term survival and this can be achieved when their employees demonstrate innovative behaviors at the workplace. Innovative behavior has thus received considerable attention from researchers, particularly on exploring the factors which foster employee innovative behaviors. Based on human resource system strength theory, the objective of this study is twofold. First, it examines the direct and indirect relationship between perceptions of performance appraisal quality (PPAQ) and innovative behavior mediated through psychological empowerment. Second, it examines the moderating effect of perceptions of HRM system strength in the hypothesized links. A total of 360 faculty members participated in the study from twelve public sector higher education institutes in Islamabad, Pakistan. Partial least squares structural equation modeling (PLS-SEM) is used for statistical analysis of the quantitative data collected through self-administered questionnaire. Results demonstrated that PPAQ is positively related with innovative behavior. The findings also support the mediating role of psychological empowerment and the moderating role of perceptions of human resource management (HRM) system strength. We contribute to the literature by demonstrating that HRM content and process are two complementary facets of an HRM system in bringing out positive work behaviors. A number of practical implications and directions for future research are outlined.
