Contemporary organizations need to dynamically adapt to their rapidly changing environment. This imposes challenges to the entire organization, including its supporting information systems (IS). However, current value management practices pay little attention to evolvability issues within the evaluation and deployment of information technology dependent strategic initiatives (ITDSIs). In this paper, we explore how the evolvability of an information technology (IT) application can be assessed and which practices might be affected if an organization is willing to address this issue. For this purpose, we propose a set of five specific management guidelines. These should lead to ITDSIs yielding more evolvable information systems to an organization, and hence enable the organization to more easily adapt to its environment, providing a competitive advantage. © 2014 IEEE.

Strategic positioning and fit theories may inform the service-based differentiation strategies that incubators use to secure external and internal alignment. External alignment relates to tenant service expectations and perceptions; internal alignment involves a competence configuration for each strategy alternative. By implementing the proposed framework, an incubator can achieve service differentiation and ultimately enhanced customer (tenant) value. Qualitative research among nonprofit economic development incubators reveals two service-based differentiation positions: specialists and generalists. Whereas extant research advocates only a specialist stance, the present analysis confirms that service-based differentiation can result from a generalist stance. This study offers the first typology of service-based differentiation strategies for incubators that aligns strategy with external and internal variables. © 2012 Elsevier Ltd.

Introduction: The aims of this study were to explore the incidence of in-hospital inappropriate empiric antibiotic use in patients with severe infection and to identify its relationship with patient outcomes. Methods: Medline (from 2004 to 2014) was systematically searched by using predefined inclusion criteria. Reference lists of retrieved articles were screened for additional relevant studies. The systematic review included original articles reporting a quantitative measure of the association between the use of (in)appropriate empiric antibiotics in patients with severe in-hospital infections and their outcomes. A meta-analysis, using a random-effects model, was conducted to quantify the effect on mortality by using risk ratios. Results: In total, 27 individual articles fulfilled the inclusion criteria. The percentage of inappropriate empiric antibiotic use ranged from 14.1% to 78.9% (Q1-Q3: 28.1% to 57.8%); 13 of 27 studies (48.1%) described an incidence of 50% or more. A meta-analysis for 30-day mortality and in-hospital mortality showed risk ratios of 0.71 (95% confidence interval 0.62 to 0.82) and 0.67 (95% confidence interval 0.56 to 0.80), respectively. Studies with outcome parameter 28-day and 60-day mortality reported significantly (P ≤0.02) higher mortality rates in patients receiving inappropriate antibiotics. Two studies assessed the total costs, which were significantly higher in both studies (P ≤0.01). Conclusions: This systematic review with meta-analysis provides evidence that inappropriate use of empiric antibiotics increases 30-day and in-hospital mortality in patients with a severe infection. © 2015 Marquet et al.; licensee BioMed Central.

This paper describes the application of Group Support Systems (GSS) in the field of Business Information Security Governance (BISG). The focus is on longitudinal small team collaboration - for instance within Boards of Directors (BoD) and groups of experts - with large amounts of items. Apart from this focus on small groups, there is an operational link to the Information Security Management cycle (Plan, Do, Check, Act i.e. ISO27000 norms). This link results for expert and management teams in collaboration on lots of items (e.g. 133 controls or in this case 228 best practices). This paper presents the findings of an initial research phase and presents a comprehensive, thoroughly selected core set of BISG practices to be used by practitioners. It shows how GSS can play a facilitating role in small team collaboration with large amounts of data. It concludes with suggestions for further empirical research into the BISG topic. © 2012 IEEE.

In two studies, we investigate how consumers cope with online reviews that are in conflict with each other. Using a 2 (review set balance: positive, negative) x 2 (review source: expert, non-expert) x 2 (review content: coherent, incoherent) experimental design, the first study investigates how readers process information when they are faced with conflicting reviews and the extent to which people use consensus heuristics (both in terms of valence and content) and source heuristics to form an impression and purchase intention. Using a 2 (valence of expert review: positive, negative) x 2 (content of expert review: coherent, incoherent) experimental design, the second study further investigates the role of expert sources and conflicting review information for impression formation and purchase intention in neutrally balanced review sets. Results indicate a strong presence of a consensus heuristic: a positive balance generates a significantly better review impression and purchase intention than a negative balance. Furthermore, our results also suggest a double discounting phenomenon: a review is more likely to be discounted when it comes from an expert and/or when the content of the review is not coherent with the rest of the reviews in the set. Implications and suggestions for further research are formulated.

A large variety of financial instruments has emerged to allow hedging of risks associated with the underlying assets, whether it is a commodity, weather or economic indicators. However, in the information security domain, cyber-insurance products are the only financial instrument available to hedge the information security risk. Furthermore, cyber-insurance markets are unable or unwilling to accept the high probability and/or high-intensity risks. Thus, there is a need for new financial instruments and a market mechanism to facilitate risk hedging in the information security domain. This article explains the limitations of cyber-insurance market and presents a novel financial instrument and a corresponding trading mechanism to address the problems in the cyber-insurance market. The proposed instrument and trading mechanism can be implemented in an information security prediction market to facilitate the hedging of the risk associated with the underlying information security event or condition. Furthermore, the article demonstrates the application of the proposed financial instrument in an imaginary scenario. Lastly, the article presents an evaluation of the proposed financial instrument and corresponding trading mechanism in hedging the underlying risk. In our analysis, we found that the proposed financial instrument can be a solution, at least to some extent, to the problems in the existing risk hedging mechanisms available in the information security domain. © 2015 IEEE.

Information Security (IS) is increasingly becoming an integrated business practice instead of just IT. Security breaches are a challenge to organizations. They run the risk of losing revenue, trust and reputation and in extreme cases they might even go under. IS literature emphasizes the necessity to govern Information Security at the level of the Board of Directors (BoD) and to execute (i.e. Plan, build, run and monitor) it at management level. This paper describes explorative research into IS-relevant Governance and Executive management practices. Answering the main research question: "Which practices at the level of Governance are relevant for Business Information Security Maturity" The initial phase of this research consists of a review of academic and practice-oriented literature on these relevant practices. This list of practices is then examined and validated through expert panel research using a Group Support System (GSS). The paper ultimately identifies a list of 22 core principles. This list can function as frame of reference for Boards of Directors and Management Teams in order to increase their level of Business Information Security (BIS) Maturity. © 2015 IEEE.

This study explores the system of intermediate organizations in Dutch health care as the crucial system to understand health care policy-making in the Netherlands. We argue that the Dutch health care system can be understood as a system consisting of distinct but inter-related policy domains. In this study, we analyze four such policy domains: Finances, quality of care, manpower planning and pharmaceuticals. With the help of network analytic techniques, we describe how this highly differentiated system of >200 intermediate organizations is structured and coordinated and what (policy) consequences can be observed with regard to its particular structure and coordination mechanisms. We further analyze the extent to which this system of intermediate organizations enables participation of stakeholders in policy-making using network visualization tools. The results indicate that coordination between the different policy domains within the health care sector takes place not as one would expect through governmental agencies, but through representative organizations such as the representative organizations of the (general) hospitals, the health care consumers and the employers' association. We further conclude that the system allows as well as denies a large number of potential participants access to the policy-making process. As a consequence, the representation of interests is not necessarily balanced, which in turn affects health care policy. We find that the interests of the Dutch health care consumers are well accommodated with the national umbrella organization NPCF in the lead. However, this is no safeguard for the overall community values of good health care since, for example, the interests of the public health sector are likely to be marginalized. © The Author (2012).

Although several studies in the wide body of literature on technology transfer have hinted at differences across industries, this still remains an understudied issue. Our study addresses this topic and considers to what degree technology transfer processes differ across different industrial sectors. To that end, we study to what extent technology transfer processes differ along both types of transfer mechanisms and key barriers inhibiting the transfer process. Based on a survey of Dutch practitioners on both sides of the transfer process, we test a number of hypotheses that differentiates between science-based regimes and development-based regimes. While our findings confirm our hypotheses concerning differences between the regimes regarding the use of specific transfer mechanisms, we also find that both regimes share a number of mechanisms that are similar. In addition, our findings show a remarkable degree of similarity among barriers inhibiting the process. We discuss these findings within the context of the broader literature and formulate policy implications. © 2011 Elsevier Ltd.

The SPARK project aims at realizing a responsive and intuitive ICT platform that exploit the potential of Spatial Augmented Reality (SAR) to show designers and customers real-like solutions in the form of mixed prototypes (partially virtual and partially physical) during brainstorming sessions. The SPARK platform allows designers and customers to freely work together within the paradigm of open-innovation so as to support and foster creative thinking with an enriched flow of ideas in the design process. The platform, by means of adequate content management and real-like interaction with the mixed prototype, will enhance the innovation capabilities of creative industries through the facilitation of brainstorming and the early assessment of design solutions in a Co-Design environment. It will enable designers and customers to cooperate since the very beginning to create the most suitable solutions according to the prompt evaluation of customers. The SPARK platform addresses the need of the creative industries of the consortium to reduce the effects of poor communication with their customers and the inefficiencies due to the asynchronous process of ideation and validation, which results in longer design cycles and a slower pace for time-to-market. The platform will be validated, against an appropriate metrics, with control groups in relevant operational and real life environments, where creativity plays a paramount role. The groups will include also customers and other user communities. The tests will aim at demonstrating the effectiveness of the platform in: (1) reducing the time needed for generating ideas, (2) reducing the amount of creative SMEs human resources on a single project (so as to allow them to manage more projects), (3) reducing the workload of the people involved in the brainstorming sessions and (4) increasing the efficiency of the whole design process, by enhancing the direct feedback by the customers on the solution of the design task.
