Purpose The purpose of this paper is to investigate how buyer–supplier social capital may help mitigate operational supply risk (OSR) of small- and medium-sized enterprises (SMEs). It empirically examines a framework that posits the direct and mediated impacts of three dimensions of buyer–supplier social capital – structural, relational and cognitive – and supplier integration on the OSR of SMEs and consequently their operational performance. Design/methodology/approach This study uses data collected via a questionnaire from 485 manufacturing SMEs in Bangladesh for analysis using structural equation modeling. Findings The analysis reveals that all the three dimensions of buyer–supplier social capital can effectively reduce the OSR of SMEs, either directly or indirectly through supplier integration. The mediating role of supplier integration in the relationship between social capital and OSR is confirmed and the negative impact of OSR on operational performances of SMEs is verified. Research limitations/implications Generalization of the findings needs to be prudent since the study gathered information only from manufacturing SMEs in Bangladesh on the buyer side of the buyer–supplier dyad. Practical implications Findings of this study can provide references for SME practitioners to formulate their OSR mitigation strategies for enhancing operational performance. Originality/value This study adds to the currently scarce literature on OSR of SMEs by combining antecedents and consequences of OSR in a single framework. It also extends the use of buyer–supplier social capital to risk mitigation research.

The realization that legacy information technology (IT) systems have environmental footprint has elevated the sustainability of IT (Green IT) as a significant IT management issue. However, there is a lack of empirical research to explain Green IT capabilities of organizations and the maturity of those capabilities. This article reports a Green IT Readiness framework to capture the input, transformational and output capabilities that organizations need to nurture in sustainable management of IT. It identifies five components of G-readiness and provides an exploratory framework and a research-ready instrument. The instrument is validated based on data collected from a crosssectional and crosscountry survey of IT managers.

Corporations continue to see a growing demand for Bring-Your-Own-Device (BYOD) programs which allow employees to use their own computing devices for business purposes. This study analyses the demand of digital natives for such programs when entering the workforce and how they perceive the benefits and risk associated with BYOD. A theoretical model building on net valence considerations, technology adoption theories and perceived risk theory is proposed and tested. International students from five countries in their final year and with relevant work experience were surveyed. The results show that the intention to enroll in a BYOD program is primarily a function of perceived benefits while risks are widely ignored. Only safety and performance risks proved to contribute significantly to the overall perceived risk. The knowledge acquired from this study is particularly beneficial to IT executives as a guide to deciding whether and how to set up or adjust corporate BYOD initiatives.

This study explores antecedents to sector based e-business use. Sectoral e-business studies are valuable to understand the absorption of e-business in dzferent economic sectors, the speczj?c challenges of using e-business across different sectors and the potential of dzferent sectors to integrate into the global digital value chain. Drawing from the perceived e-readiness model (PERM) and the Organizational, Technological and Environmental (OTE) framework, an integrated e-business use model is proposed. Data were collected from a survey offirms in the horticulture sector inAustralia. Empirical analysis of the integrated model show that e-business use within the horticulture sector is at the initial state of maturity. In terms of the antecedent factors, this research shows that technology competence, financial commitment, perceived environmental e-readiness and organizational size are influential factors that directly affect e-business use. Perceived organizational e-readiness has an indirect influence on e-business use. The implications of these findings to both global IT management and e-business research are discussed. Practitioners such as governments, horticulture associations, growers and growers associations and digital marketplace operators, through understanding these factors affecting e-business use, can make effective decisions to develop their support, capabilities and oferings respectively.
