The healthcare sector has undergone a number of transformations in recent years, partly due to recent advances in technology. This triggered our study to examine patients' desire to seek health information largely driven by increased access via the Internet and the cumulative impacts on value co-creation. We employed a sequential exploratory design involving a phenomenological approach in the qualitative phase, followed by a quantitative survey design to further our understanding of the influence of technology in co-creating value in healthcare at the micro level. Advances in technology have empowered patients to be informed, which enabled them to play an active role in clinical encounters with the doctor. The findings suggest pre-encounter information search impacts positively on improved service engagement and commitment to compliance with medical instructions. It does this by shaping the nature of interactions, enhancing provider-patient orientation, and increasing their involvement in a shared decision-making process. From a theoretical perspective, our study integrates multiple research perspectives (e.g., access to information, online information seeking and knowledge creation, healthcare consultation models, etc.) and extends research on patient integration, participation, and co-creation of value. The conceptualization of value co-creation activities in this study suggests a need for service providers to adopt delivery approaches that would effectively integrate patient resources to co-create value.

The information systems research on generativity promises unprompted, innovative inputs from uncoordinated audiences, whose participation with heterogeneous technological resources generates diverse outputs and opens new possibilities. The question is how to perpetuate the openness on which the outputs of generativity rely. We advance, as a potential mechanism of generativity, the concept of digital probes, which leverage human and technological resources in hybrid digital and physical environments. The aesthetically rich probes challenge values, identities, and practices, cultivating emotional tensions that can reveal previously unexplored and unimagined possibilities, resulting in novel ideas, thoughts, and expressions. The new possibilities reveal what is hidden; reconfigure practices; cross-appropriate technological and social resources; and thereby further expand what can be experienced, viewed, and imagined. Further, the new possibilities draw new actors that again view things differently and seek different experiences, thus fueling emotional tensions that in turn open new possibilities, without settling them. We illustrate digital probes and their effects at Formula E. Formula E is a new motorsports venture that leveraged eSports, social media, crowdsourcing, and driverless cars in digital probes to reveal and examine previously unimagined possibilities of what the world of motorsport could be in the digital era. We end by exploring future research directions.

We study the association between daily changes in short selling activity and financial stock prices during extreme events using TailCoR, a measure of tail correlation. For the largest European and US banks, as well as European insurers, we uncover a strong relation during exceptional (extreme) days and a weak relation during normal (average) days. Examining days with large increases in short positions and large downfalls in stock prices, we find evidence of both momentum and contrarian short selling taking place. For North American bank stocks, contrarian short selling appears more practiced than for European bank and insurance stocks. We find that the uncovered relationship decreases with firm size and increases during ban periods, which is in line with short selling becoming more informative when constrained.
The concept of degrowth aims fundamentally at reducing material and energy throughput equitably, while questioning the desirability of further economic growth. In order to achieve this reduction of society’s throughput, radical changes in the ways goods and services are produced, distributed and used are required. In this think piece, concepts of consumer integration into the value creation process and (new) enabling technologies are discussed as possible constituting elements of alternative organizational models in a degrowth society. To date, collaborative value creation concepts, such as crowdsourcing and mass customization, have been discussed almost exclusively as business model patterns for companies in economies that are set to grow. The same applies to the assessment of (new) technologies, such as additive manufacturing, web-based user interfaces for co-creation, and other flexible production technologies that allow for collaborative and individualized production. Potential positive and negative effects of these concepts and technologies with regard to the objectives of degrowth are discussed in order to initiate a debate about the inclusion of CVC for the design of alternative organizational models that are in line with degrowth thinking. This think piece illustrates that several elements of collaborative value creation and its enabling technologies coincide with degrowth objectives but do not lead per se to their attainment. Thereby, a starting point for future (empirical) work in this area is generated.

We measure systemic risk via the interconnections between the risks facing both financial and real economy firms. SIFIs are ranked by building on the Google PageRank algorithm for finding closest connections. For a panel of over 500 US firms over 2003–2011 we find evidence that intervention programs (such as TARP) act as circuit breakers in crisis propagation. The curve formed by the plot of firm average systemic risk against its variability clearly separates financial firms into three groups: (i) the consistently systemically risky (ii) those displaying the potential to become risky and (iii) those of little concern for macro-prudential regulators.
Given the lack of insights into the micro-determinants of strategic planning (SP) in public organizations, this study uses information-processing theory and self-efficacy theory to investigate individual-level predictors of commitment to strategic plans among planning team members (PTMs). Specifically, we investigate whether plan commitment is contingent upon the fit between PTMs' preferred way of information-processing (i.e. their cognitive style) and the information-processing characteristics underlying SP processes in public organizations. Based on data gathered with 439 PTMs from 203 Flemish municipalities, we find that PTMs with a creating and planning style are committed to strategic plans because they deem SP useful.

In this article, we present how Barco, a global technology company, used an operations research optimization model, which was supported by an efficient solution method, to implement platforms—common structures from which sets of products could be made—for the design and production of its high-tech medical displays. Our optimization model captures all cost aspects related to the use of platforms, thus, it is an objective tool that considers the input from marketing, sales, research and development (R&D), operations, and the supply chain. This comprehensive view allowed Barco to avoid the excessive costs that may result from the implementation of an incorrect platform. Our model supported Barco in determining the elements that should comprise each platform, the number of platforms to develop, and the products to derive from each platform. The results of the project led to reductions in safety stock and increased flexibility due to the use of platforms: R&D can now introduce twice as many products using the same resources, thus increasing Barco's earnings by over 5 million euros annually and reducing product introduction time by nearly 50 percent.

In this paper we develop a theoretical framework about how leaders help shape the impact of HR diversity practices on employee inclusion. So far, the HR literature has given leaders a relatively passive role in that they are mainly seen as enactors and communicators of HR policies and practices. We expand this view by suggesting that leaders can respond to HR's (diversity) practices with various levels of alignment (or misalignment), and clarify the respective implications for felt inclusion. Informed by literature on multiple identities at work, we derive four potential responses of leaders to HR's diversity practices—deletion, compartmentalization, aggregation, and integration. We show how these responses shape the eﬀects of diversity practices on employee inclusion, and in doing so, we also question a commonly held assumption that leaders' full alignment with HR's diversity practices is the most conducive for employees' felt inclusion. Our frameworkhasimportant implications fortheoryand practice,asit speciﬁesthe roleof leadersin leveraging the inclusive potential of HR diversity practices.

In a paper written by by Vanhoucke et al. (2016), an overview of artificial and empirical project databases has been given for integrated project management and control. These databases are collections of the most well-known and widespread data instances available in literature for the construction of a baseline schedule, the analysis of schedule risk or the use for project control. The current paper serves as a follow-up study to further elaborate on the use of these data instances, and to give researchers an incentive to use these datasets for their research on the development and validation of new algorithms for project scheduling. Therefore, unlike the general focus of the previous paper on baseline scheduling, schedule risk analysis and project control, the focus on the current paper is restricted to resource-constrained project scheduling. The intention of this follow-up overview is fourfold. First and foremost, a procedure is proposed to facilitate the reporting of best known solutions for the well-known single- and multi-mode resource-constrained project scheduling problem to minimize the project makespan. Secondly, the paper reports our best known solutions we obtained so far, and reflects on the network and resource parameters that increase the project complexity. In doing so, areas to focus on for future research are detected, and an attempt to define hard problem instances is given. Thirdly, a new dataset is presented for the resource-constrained project scheduling problem that is much more diverse in both the network topology and resource scarceness and will enable the future researcher to develop algorithms to solve a wider range of project problems. Finally, the paper also adds some links to tutorials and other relevant information to stimulate researchers to download the data and update best known solutions once available.

Greater use of multimodal transportation can substantially improve the environmental performance of freight transportation. Despite strenuous efforts by public policy-makers to alter the freight modal split, most companies still rely heavily on road transportation, and modal shifts to rail and water have remained modest at best. In this paper we argue that this is partly the result of a failure to take a holistic supply chain view of the modal shift process. Synchromodality provides a framework within which shippers can manage their supply chains more flexibly to increase the potential for shifting mode. On the basis of a literature review, we broaden the conventional focus of multimodal transportation to give it a supply chain dimension, and propose the concept of ‘Synchromodality from a Supply Chain Perspective' (SSCP). Using a case study we show that when the supply chain impacts are taken into account, it is possible to significantly increase the share of intermodal rail transportation within a corridor, without necessarily increasing total logistics cost or reducing the service level. In this way the environmental impact of freight activities can be significantly reduced.
