Although prior research has examined the influence of technostress creators on job outcomes, insights into the influence of personality traits on the perceptions of technostress creators and their consequent impacts on job outcomes are rather limited. Such insights would enable a deeper understanding about the effects of individual differences on salient job-related outcomes. In this research, by leveraging the distinctions in personality traits offered by the big five personality traits in the five-factor model and grounding the research in the transactional model of stress and coping, we theorise the moderating influence of personality traits on the relationships between technostress creators and job outcomes, namely job burnout and job engagement. Specifically, the study theorises the mechanisms through which each of the specific personality traits openness-to-experience, neuroticism, agreeableness, conscientiousness and extraversion interacts with technostress creators to differently influence job burnout and job engagement. We test the proposed model in a field study based on a survey of senior organisational managers who regularly use information and communication technologies for executing professional tasks. Although technostress creators are generally associated with negative job outcomes, our results also show that for individuals with certain personality traits, technostress creators may result in positive job outcomes. The study thus contributes to the technostress literature, specifically by incorporating the salient role of individual differences. The study also provides insights for managers who should pay special attention to allocating specific job roles to employees with particular personality traits in order to optimise job-related outcomes

Despite the numerous studies on the topic of IT employee turnover and recommendations to organizations on how to retain their employees, the general turnover trend of IT professionals remains high. The need for further research on IT turnover has been called for by many, but much of the literature continues to conduct similar studies using the same constructs, and these studies find similar results. Now is the time to turn our research attention to directions that have been unexplored or less explored. Newer research directions for the IT turnover literature will provide insights for refining and easing the impact of turnover on organizations. As we embark on new research frontiers in the IT turnover phenomenon, a comprehensive review and assessment of the state of the literature may facilitate future research in building off of existing knowledge. This paper reviews and assesses the existing literature on the voluntary turnover of IT employees, identifies the areas where research has matured, and raises directions for future research that are less chartered

Time series properties of the renewable energy diffusion process: Implications for energy policy design and assessment

Confronted by increasingly tight budgets and a broad range of alternative options, policy makers need empirical methods to evaluate the effectiveness of policies aimed at supporting the diffusion of renewable energy sources (RES). Rigorous empirical studies of renewable energy policy effectiveness have typically relied on panel data models to identify the most effective mechanisms. A common characteristic of some of these studies, which has important econometric implications, is that they assume that the contribution of RES to total electricity generation will be stationary around a mean. This paper reviews such assumptions and rigorously tests the time series properties of the contribution of RES in the energy mix for the presence of a unit root. To that end, we use both individual and panel unit root tests to determine whether the series exhibit non-stationary behavior at the country level as well as for the panel as a whole. The analysis, applied to a panel of 19 OECD countries over the period 1990-2012, provides strong evidence that the time series of the renewable share of electricity output are not stationary in 17 of the 19 countries examined. This finding has important implications for energy policy assessment and energy policy making, which are discussed in the paper

Despite the potential benefits, many organizations have failed in service-oriented architecture (SOA) implementation projects. Prior research often used a variance perspective and neglected to explore the complex interactions and timing dependencies between the critical success factors. This study adopts a process perspective to capture the dynamics while providing a new explanation for the mixed outcomes of SOA implementation. We develop a system dynamics model and use simulation analysis to demonstrate the phenomenon of “tipping point.” That is, under certain conditions, even a small reduction in the duration of normative commitment can dramatically reverse, from success to failure, the outcome of an SOA implementation. The simulation results also suggest that (1) the duration of normative commitment can play a more critical role than the strength, and (2) the minimal duration of normative commitment for a successful SOA implementation is associated positively with the information delay of organizational learning of SOA knowledge. Finally, we discuss the theoretical causes and organizational traps associated with SOA implementation to help IT managers make better decisions about their implementation projects

Efficient purchaser incentive when dealing with suppliers implementing continuous improvement plans

Mots clés : Continuous improvement, Dynamic programming, Purchaser incentives, Stochastic decision process

This paper presents incentive schemes in the framework of a collaborative purchasing cost reduction process with a supplier implementing a continuous improvement plan. Using a stochastic decision process formulation, we analyze the structure of the optimal policy and characterize its numerical robustness through numerical applications solved by dynamic programming. Then, we analyze two purchaser incentive schemes observed in practice. First, we describe some theoretical properties of the policies associated with these two schemes (schemes I and II) and show that these policies exhibit nonoptimal structures. Second, we estimate the quantitative loss for typical parameter values and, in particular, we show that for certain businesses this loss is significant. Then, we propose two easy-to-implement improvements (schemes III and IV), which result in near-optimal solutions and a significant impact on purchasing cost performances

Online communities bring together individuals with shared interest in joint action or sustained interaction. Power lawdistributions of user popularity appear ubiquitous in online communities but their formation mechanisms are not wellunderstood. This study tests for the formation of power law distributions via the mechanisms of preferential attachment,least efforts, direct reciprocity, and indirect reciprocity. Preferential attachment, where new entrants favor connectionswith already popular participants, is the predominant explanation suggested by prior literature. Yet, the attribution ofpreferential attachment or any other mechanism as a single unitary reason for the emergence of power law distributionsruns contrary to the social nature of online communities and does not account for diversity of participants’ motivation.Agent-based modeling is used to test if a single social mechanism alone or multiple mechanisms together can generatepower law distributions observed in online communities. Data from 28 online communities is used to calibrate, validate,and analyze the simulation. Simulated communication networks are randomly generated according to parameters foreach hypothesis. The fit of the power law distribution in the model testing subset is then compared against the fit forthese simulated networks. The major finding is that, in contrast to research in more general network settings, neitherpreferential attachment nor any other single mechanism alone generates a power law distribution. Instead, a blendedmodel of preferential attachment with other social network formation mechanisms was most consistent with power lawdistributions seen in online communities. This suggests the need to move away from stylized explanations of networkemergence that rely on single theories toward more highly socialized and multitheoretic explanations of communitydevelopment

Contemporary offshore Information System Development (ISD) outsourcing is becoming even more complex. Outsourcing partner has begun ‘re-outsourcing’ components of their projects to other outsourcing companies to minimize cost and gain efficiencies. This paper aims to explore intra-organizational Information Asymmetry of re-outsourced offshore ISD outsourcing projects.Design/methodology/approach - An online survey was conducted to get an overall view of Information Asymmetry between Principal and Agents (as per the Agency theory).Findings - Statistical analysis showed that there are significant differences between the Principal and Agent on clarity of requirements, common domain knowledge and communication effectiveness constructs, implying an unbalanced relationship between the parties. Moreover, our results showed that these three are significant measurement constructs of Information Asymmetry.Research limitations/implications - In our study we have only considered three main factors as common domain knowledge, clarity of requirements and communication effectiveness as three measurement constructs of Information Asymmetry. Therefore, researches are encouraged to test the proposed constructs further to increase its precision.Practical implications - Our analysis indicates significant differences in all three measurement constructs, implying the difficulties to ensure that the Agent is performing according to the requirements of the Principal. Using the Agency theory as theoretical view, this study sheds light on the best contract governing methods which minimize Information Asymmetry between the multiple partners within ISD outsourcing organizations.Originality/value - Currently, to the best of our knowledge, no study has undertaken research on Intra-organizational Information Asymmetry in re-outsourced offshore ISD outsourcing projects

We study the operational implications from competition in the provision of healthcare services, in the context of national public healthcare systems in Europe. Specifically, we study the potential impact of two alternative ways through which policy makers have introduced such competition: (i) via the introduction of private hospitals to operate alongside public hospitals and (ii) via the introduction of increased patient choice to grant European patients the freedom to choose the country they receive treatment at. We use a game-theoretic framework with a queueing component to capture the interactions among the patients, the hospitals and the healthcare funders. Specifically, we analyze two different sequential games and obtain closed form expressions for the patients’ waiting time and the funders’ reimbursement cost in equilibrium. We show that the presence of a private provider can be beneficial to the public system: the patients’ waiting time will decrease and the funders’ cost can decrease under certain conditions. Also, we show that the cross-border healthcare policy, which increases patient mobility, can also be beneficial to the public systems: when welfare requirements across countries are sufficiently close, all funders can reduce their costs without increasing the patients’ waiting time. Our analysis implies that in border regions, where the cost of crossing the border is low, “outsourcing” the high-cost country’s elective care services to the low-cost country is a viable strategy from which both countries’ systems can benefit

Les filiales d’une multinationale doivent concilier adaptation locale et intégration globale. Pour analyser cela, nous proposons la notion de déploiement d’innovations inter-filiales que nous définissons comme l’enchaînement des commercialisations d’une innovation par des filiales situées dans des contextes locaux différenciés, et nécessitant ainsi à chaque fois son adaptation. A partir d’une analyse longitudinale de cinq déploiements d’innovations dans une multinationale, nous mettons en évidence quatre facteurs critiques que nous relions à des dispositifs de construction et de partage de connaissances. Nous discutons ainsi le modèle théorique de transfert de connaissances de Tallmann et Chacar (2011) et en précisons les conditions de mise en oeuvre

Motivated by an increasing adoption of evidence-based medical guidelines in the delivery of medical care, we examine whether increased adherence to such guidelines (typically referred to as higher process quality) is associated with reduced resource usage in the course of patient treatment. In this paper, we develop a sample of US hospitals and use cardiac care as our context to empirically examine our questions. To measure a patient's resource usage we use the total length of stay, which includes any additional inpatient stay necessitated by unplanned readmissions within thirty days after initial hospitalization. We find evidence that higher process quality, and more specifically its clinical (as opposed to its administrative) dimensions, are associated with a reduction in resource usage. Moreover, the standardization of care that is achieved via the implementation of medical guidelines, makes this effect more pronounced in less focused environments: higher process quality is more beneficial when the cardiac department's patient population is distributed across a wider range of medical conditions. We explore the implications of these findings for process-oriented pay-for-performance (P4P) programs, which tie the reimbursement of hospitals to their adherence to evidence-based medical guidelines
