This article examines how institutional pressures affect the adoption of green IS & IT across organizations. From the natural-resource-based perspective, it examines green IS & IT practices with strategic foci on pollution prevention, product stewardship, and sustainable development. Each category incorporates the separate roles played by IT (as a problem) and IS (as a solution). The partial least square method was employed to analyze the survey replies from 75 organizations. The results show that mimetic and coercive pressures significantly drive green IS & IT adoption. In particular, outcomebased imitation and imposition-based coercion represent major institutional processes. The results also suggest the complementary relationship between mimetic and coercive pressures. Such interaction significantly motivates the green IS & IT adoption focusing on product stewardship. These findings contribute to existing knowledge on the proenvironmental behaviors of organizations, demonstrate the interaction between institutional forces, and further current understanding of green IS & IT adoption The study concludes with a general discussion of eco-goals and their relationship to institutional theory before considering the implications and directions for research and practice.

Purpose The purpose of this paper is to investigate whether four motives – conformity, enhancement, social and coping – mediate relationships between four personality types – agreeableness, extraversion, neuroticism and openness to experience – and social networking site (SNS) addiction. Impulse control is included as a moderator. Design/methodology/approach The paper uses a survey to collect data at two points in time from 304 SNS users. Structural equation modeling was used for data analysis. Findings Empirical results show that conformity, enhancement and coping motives act as mediators between various personality types and SNS addiction. Furthermore, impulse control weakens the effects of two motives – enhancement and social – on SNS addiction. Research limitations/implications The research model included only four motives. Future research could investigate other motivational mechanisms and moderators. The research method surveyed university students in the USA; thus, results may not generalize to a different user population. The method also included only one SNS, Facebook. Originality/value The paper contributes to the literature by showing that motives of SNS use connect personality to SNS addiction. This study also shows that self-reflective factors like impulse control can reduce the positive effects of motives on SNS addiction.
