TL;DR: The findings offer a roadmap for disseminating green purchasing across the subsidiaries of an MNC, as well as highlighting the importance of both clear communication about the benefits of green purchasing and internal audits.
Abstract: To examine the essential determinants of green purchasing by multinational corporations� (MNC) subsidiaries, this study takes institutional theory as a foundation and focuses on the institutional duality associated with localization and globalization. Specifically, we develop a model to explain subsidiaries� green purchasing and empirically test the model with data from 141 purchasing managers and senior purchasing staff members from subsidiaries in 39 countries. Our results suggest that pressures from headquarters and the local environment do not affect subsidiaries� green purchasing directly; rather, they exert indirect influences through local tailoring. This study contributes to extant literature by revealing the significance of local tailoring in an MNC context. In addition, our findings offer several implications for practice by providing a roadmap for disseminating green purchasing across the subsidiaries of an MNC, as well as highlighting the importance of both clear communication about the benefits of green purchasing and internal audits.

TL;DR: An integrated framework that offers an infrastructure necessary for accessing, integrating, and analyzing multilingual user-generated content from different social media sites is proposed and the Dark Web Forum Portal (DWFP) is developed that supports the gathering and analyses of social media content concerning security.
Abstract: The growth of Web 2.0 has produced enormous amounts of user-generated content that contains important information about individuals' attitudes, perceptions, and opinions toward products, social events, and political issues. The volume of such content is increasing exponentially, making its search, analysis, and use more difficult and thus favoring advanced tools that aid in information search and processing. We propose an integrated framework that offers an infrastructure necessary for accessing, integrating, and analyzing multilingual user-generated content from different social media sites. Building on this framework, we develop the Dark Web Forum Portal (DWFP) that supports the gathering and analyses of social media content concerning security. Our evaluation results show that users supported by DWFP complete tasks better and faster than those using the benchmark forum. Participants consider DWFP to be better in terms of system quality, usefulness, ease of use, satisfaction and intention to use.

TL;DR: The IDT appears capable of explaining workers' technology acceptance better than does TPB or TAM, and both perceived usefulness and perceived ease of use remain significant determinants of attitude and intention.
Abstract: Cultural considerations could affect individuals' behaviors, including their technology acceptance. This study analyzes the acceptance of computer technology by 1,088 workers in 56 Arabian organizations to reexamine and compare the theory of planned behavior (TPB), technology acceptance model (TAM), and innovation diffusion theory (IDT). The explanatory power of each theory or model seems lower among Arabian workers, as compared with users in Western, developed countries. The IDT appears capable of explaining workers' technology acceptance better than does TPB or TAM. Perceived behavioral control and subjective norms constitute more important acceptance determinants than does attitude. Both perceived usefulness and perceived ease of use remain significant determinants of attitude and intention; however, considering findings reported by previous research, their total effects are comparable in magnitude and statistical significance. The findings are incongruent with the results of several representative prior studies that examine the same theories and models, which in turn offer several implications from a sociocultural perspective.

TL;DR: It is documented that a firm’s investments in IT components exhibit different impacts on its profitability conditional on the level of investments in complementary components, which is unique in that it examines complementarities between distinct IT components.
Abstract: Prior research has documented that IT investment increases market returns. Economic theories predict such returns to be recognized in accounting profitability; this relationship remains ambiguous in prior literature. We reexamine the relationship between IT investment and firm profitability. Our approach is unique in that we examine complementarities between distinct IT components. We document that a firm’s investments in IT components exhibit different impacts on its profitability conditional on the level of investments in complementary components.
