Limited attention has been directed toward examining post-adoption stages of the information system life cycle. In particular, the final stages of this life cycle have been largely ignored despite the fact that most systems eventually reach the end of their useful life. This oversight is somewhat surprising given that end-of-life decisions can have significant implications for user effectiveness, the value extracted from IS investments, and organizational performance. Given this apparent gap, a multi-method empirical study was undertaken to improve our understanding of organizational level information system discontinuance. Research commenced with the development of a broad theoretical framework consistent with the technology-organization- environment (TOE) paradigm. The resulting framework was then used to guide a series of semi-structured interviews with organizational decision makers in an effort to inductively identify salient influences on the formation of IS discontinuance intentions. A set of research hypotheses were formulated based on the understanding obtained during these interviews and subsequently tested via a random survey of senior IS decision makers at U.S. and Canadian organizations. Data obtained from the survey responses was analyzed using partial least squares (PLS). Results of this analysis suggest that system capability shortcomings, limited availability of system support, and low levels of technical integration were key determinants of increased intentions to replace an existing system. Notably, investments in existing systems did not appear to significantly undermine organizational replacement intentions despite support for this possibility from both theory and our semi-structured interviews.

In many business markets, manufacturers seek service-led growth to secure their existing positions and continue to grow in increasingly competitive environments. Using longitudinal data from 513 German mechanical engineering companies and latent growth curve modeling, this study offers a fine-grained view of the financial performance implications of industrial service strategies. By disentangling the revenue and profit implications of industrial service strategies, findings reveal that such strategies increase both the level and the growth of manufacturing firms' revenue streams. In contrast, they reduce the level but improve the growth of manufacturers' profits. Results further suggest that services supporting the clients' actions (SSC) and services supporting the supplier's product (SSP) affect performance outcomes in different ways. SSCs directly affect revenue and profit streams. In turn, SSPs display only indirect effects on financial performance mediated through SSCs. A moderator analysis identifies two organizational contingencies that facilitate service business success: Only companies with decentralized decision-making processes and a high share of loyal customers can expect favorable financial results from industrial service strategies. In summary, this research provides significant insights and managerial guidance for turning service strategies into financial successes. © The Author(s) 2013.

This study examines the performance of the Advanced Research core of Weather Research and Forecasting (ARW-WRF) model in prediction of the Bay of Bengal cyclone ‘Phailin’. The two-way interactive double-nested model at 27 and 9-km resolutions customized at Indian Institute of Technology Kharagpur (IITKGP) is used to predict the storm on real-time basis and five predictions are made with five different initial conditions. The initial and boundary conditions for the model are derived from the Global Forecasting System (GFS) analysis and forecast respectively. The track of storm is well predicted in all the five forecasts. In particular, the forecast with less initial positional error led to more accurate track and landfall prediction. It is observed that the predicted peak intensity and translation speed of the storm depends strongly on initial intensity error, vertical wind shear and vertical distribution of maximum potential vorticity. The trend of intensification and dissipation of the storm is well predicted by the model in terms of central sea level pressure (CSLP). The intensity in terms of maximum surface wind (MSW) is under-predicted by the model and it is suggested that the MSW estimated from predicted pressure drop may be used as prediction guideline. The storm intensified rapidly during its passage over the high Tropical Cyclone Heat Potential zone and is reasonably well predicted by the model. Though the magnitude of the precipitation is not well predicted, distribution of precipitation is fairly well predicted by the model. The track and intensity of the storm predicted by the customized WRF-ARW is better than that of other NWP models. The landfall (time and position) is also better predicted by the model compared to other NWP models if initialized at cyclonic storm stage. The results indicate that the customized model have good potential for real-time prediction of Bay of Bengal cyclones and encourage further investigation with larger number of cyclones. © 2015, Springer Basel.

This paper argues that Gibson's concept of affordance inserts a powerful conceptual lens for the study of sociomateriality as enacted in contemporary organizational practices. Our objective in this paper is to develop a comprehensive view of affordances that builds upon the existing conceptualizations in the psychology, human-computer interaction, sociology and information systems literatures and extend them in three important ways. First, we show that taking an integrative interpretation of affordance as dispositional and relational, rather than the standard unidimensional interpretation, provides a theoretical articulation of how the material and the social influence each other. Second, we propose to broaden the focus from the affordances of technology to the affordances for practice provided jointly by technology and organizing. This means considering social affordances alongside technological affordances. Finally, we argue that the best way to integrate the study of social and technological affordances is not to stretch Gibson's original concept to include the social but rather to complement it with a sociological concept that fits it neatly: Bourdieu's idea of habitus. Our claim is that the concepts of affordance and habitus complement and complete each other. Affordance offers a useful way of thinking about how practice is patterned by the social and physical construction of technology and the material environment and habitus offers a useful way of thinking about how practice is patterned by social and symbolic structures. We describe how affordances and habitus may be used together to provide a theoretical apparatus to study practice as a sociomaterial entanglement, thus adding to the methodological toolkit of scholars embracing a sociomaterial perspectives. © 2014 Elsevier Ltd.

As the broad link between small and medium-sized firm activity and key policy goals such as employment or economic growth has become generally accepted, the conversation has focused on a more nuanced understanding of the entrepreneurial engines of economic activity. A significant body of research looking at antecedents to venture performance has identified that entrepreneurial talent variables account for meaningful differences in venture performance and that significant heterogeneity exists across performance measures. These are important issues for institutions and policy makers seeking to achieve specific economic goals (e.g.; survival or growth of ventures, employment or revenue). Using meta-analysis, we integrate this work to view connections between aspects of entrepreneurial talent and different performance outcomes. Our investigation includes 50,045 firms (K of 183 studies) and summarizes 1002 observations of small and medium-sized firms. Analysis of these data yields an unexpectedly weak connection between education and performance. Furthermore, growth, scale (number of employees) and sales outcomes are significantly related to planning skills, while profit and other financial and qualitative measures are strongly connected with the network surrounding the firm founders. Moreover, we observe that entrepreneurial talent is more relevant in developing economies. © 2013 Elsevier B.V. All rights reserved.
