Physical impacts from climate change already pose major challenges for organizations, and the trend is rising. Organization theorists, however, have barely begun to systematically consider the organizational impacts of more and increasingly intense storms, floods, droughts, fires, sea level rise or changing growing seasons as part of their domain of study. Eight organizationally relevant dimensions of climate impacts are identified: severity, temporal scale, spatial scale, predictability, mode, immediacy, state change potential and accelerating trend potential. Combined, their scale, scope and systemic uncertainty suggest future conditions of systemic hyperturbulence in organizational environments, defined here as 'massive discontinuous change' (MDC). To build a conceptual foundation for organizations to respond and adapt to MDC, the paper examines contributions from literatures on the management of sustainability, crisis, risk, resilience and adaptive organizational change. It highlights gaps for addressing both business challenges and opportunities from MDC, and suggests avenues for future research. © 2010 John Wiley & Sons, Ltd. and ERP Environment.

We revisit the characterization of the Shapley value by van den Brink (Int J Game Theory, 2001, 30:309-319) via efficiency, the Null player axiom, and some fairness axiom. In particular, we show that this characterization also works within certain classes of TU games, including the classes of superadditive and of convex games. Further, we advocate some differential version of the marginality axiom (Young, Int J Game Theory, 1985, 14: 65-72), which turns out to be equivalent to the van den Brink fairness axiom on large classes of games. © Springer Science+Business Media, LLC. 2009.

We revisit the Nowak (Int J Game Theory 26:137-141, 1997) characterization of the Banzhaf value via 2-efficiency, theDummy player axiom, symmetry, and marginality. In particular, we provide a brief proof that also works within the classes of superadditive games and of simple games. Within the intersection of these classes, one even can drop marginality. Further, we show that marginality and symmetry can be replaced by van den Brink fairness/differentialmarginality. For this axiomatization, 2-efficiency can be relaxed into superadditivity on the full domain of games. © Springer Science+Business Media, LLC. 2010.

Companies wishing to engage in multisensory marketing by adding previously unused sensory modalities to their brands need to ask how their brand identity translates into these unoccupied modalities. Identifying brand identity congruent sensory modalities in a unisensory fashion is not helpful as multisensory interaction effects change their meaning. Furthermore, existing sensory evaluation techniques do not meet the requirements of marketing managers to serve this purpose. This article addresses this gap by first analysing a multisensory marketing strategy of adding previously unused sensory modalities to an existing brand. Theory supports this strategy, because it enhances the recognition, evaluation and memory of the brand and lets the brand profit from multisensory enhancement. Paramount for this strategy to work is to guarantee the congruency between the newly added sensory modalities with the existing ones of the brand and the brand personality. Therefore, as a second goal, this article proposes a conceptual framework to assess the congruency of sensory modalities in a multisensory semantic context. A three-step process is presented that draws on evaluation techniques used to assess congruency in psychology and the sensory evaluation of food. © 2015 Macmillan Publishers Ltd.

This article focuses on how to ensure resource adequacy in Germany during the transition period away from a conventional towards a renewable based electricity supply system. Sufficient thermal capacity is currently in place, as the market has not seen a full investment cycle since the liberalization in the late 1990s. Renewable production is subsidized with a feed-in tariff reducing running hours of thermal plants significantly. Power plant owners are not responsible for resource adequacy and only keep profitable capacity available. Thermal plants are still required to balance demand and the fluctuating renewable supply. The author formulates a self-selective quantity based capacity market as safety net, which supports the ambitious climate protection targets and ensures resource adequacy. This is achieved by preferring thermal capacity with low carbon dioxide emissions and high load gradients, while assigning accruing costs on a costs-by-cause principle to the non-steerable renewables. © 2015 IEEE.

We discuss the possible nature and role of non-physical entanglement, and the classical vs. non-classical interface, in models of human decision-making. We also introduce an experimental setting designed after the double-slit experiment in physics, and discuss how it could be used to discriminate between classical and non-classical interference effects in human decisions. © 2013 Cognitive Science Society, Inc.

We study team decision problems where communication is not possible, but coordination among team members can be realized via signals in a shared environment. We consider a variety of decision problems that differ in what team members know about one another's actions and knowledge. For each type of decision problem, we investigate how different assumptions on the available signals affect team performance. Specifically, we consider the cases of perfectly correlated, i.i.d., and exchangeable classical signals, as well as the case of quantum signals. We find that, whereas in perfect-recall trees (Kuhn 1950 Proc. Natl Acad. Sci. USA 36, 570-576; Kuhn 1953 In Contributions to the theory of games, vol. II (eds H Kuhn, A Tucker), pp. 193-216) no type of signal improves performance, in imperfect-recall trees quantum signals may bring an improvement. Isbell (Isbell 1957 In Contributions to the theory of games, vol. III (edsMDrescher, A Tucker, PWolfe), pp. 79-96) proved that, in non-Kuhn trees, classical i.i.d. signals may improve performance. We show that further improvement may be possible by use of classical exchangeable or quantum signals. We include an example of the effect of quantum signals in the context of high-frequency trading. © 2015 The Author(s) Published by the Royal Society. All rights reserved.

Advances in Health Care Management | Year: 2015

Purpose-Hospitals worldwide are facing the same opportunities and threats: the demographics of an aging population; steady increases in chronic diseases and severe illnesses; and a steadily increasing demand for medical services with more intensive treatment for multi-morbid patients. Additionally, patients are becoming more demanding. They expect high quality medicine within a dignity-driven and painless healing environment. The severe financial pressures thatthese developments entail oblige care providers to more and more cost-containment and to apply process reengineering, as well as continuous performance improvement measures, so as to achieve future financial sustainability. At the same time, regulators are calling for improved patient outcomes. Benchmarking and best practice management are successfully proven performance improvement tools for enabling hospitals to achieve a higher level of clinical output quality, enhanced patient satisfaction, and care delivery capability, while simultaneously containing and reducing costs. Approach-This chapter aims to clarify what benchmarking is and what it is not. Furthermore, it is stated that benchmarking is a powerful managerial tool for improving decision-making processes that can contribute to the above-mentioned improvement measures in health care delivery. The benchmarking approach described in this chapter is oriented toward the philosophy of an input-output model and is explained based on practical international examples from different industries in various countries. Findings-Benchmarking is not a project with a defined start and end point, but a continuous initiative of comparing key performance indicators, process structures, and best practices from best-in-class companies inside and outside industry. Benchmarking is an ongoing process of measuring and searching for best-in-class performance: • Measure yourself with yourself over time against key performance indicators • Measure yourself against others • Identify best practices • Equal or exceed this best practice in your institution • Focus on simple and effective ways to implement solutions Comparing only figures, such as average length of stay, costs of procedures, infection rates, or out-of-stock rates, can lead easily to wrong conclusions and decision making with often-disastrous consequences. Just looking at figures and ratios is not the basis for detecting potential excellence. It is necessary to look beyond the numbers to understand how processes work and contribute to best-in-class results. Best practices from even quite different industries can enable hospitals to leapfrog results in patient orientation, clinical excellence, and cost-effectiveness. Originality/value-Despite common benchmarking approaches, it is pointed out that a comparison without "looking behind the figures" (what it means to be familiar with the process structure, process dynamic and drivers, process institutions/rules and process-related incentive components) will be extremely limited referring to reliability and quality of findings. In order to demonstrate transferability of benchmarking results between different industries practical examples from health care, automotive, and hotel service have been selected. Additionally, it is depicted that international comparisons between hospitals providing medical services in different health care systems do have a great potential for achieving leapfrog results in medical quality, organization of service provision, effective work structures, purchasing and logistics processes, or management, etc. © 2015 by Emerald Group Publishing Limited.

Both the logistics as well as the production management have to face challenging requirements nowadays. Not only evolutions in markets and new organizational structures induce important both systems and methods adaptations, but especially the enhanced application of information and communication technologies along the worldwide distributed value creation chain results in a sustainable paradigmatic change. While in the field of production an already field-tested concept, the production system approach exists to meet the various demands, a similar concept is lacking in the area of IT-based Logistics. The given resemblances between the two disciplines favor a transfer of concept by reference modeling of an IT-based Logistics System depending on the production system framework. © 2010 Springer-Verlag.

This papers addresses the question how mass customization firms use communities to improve customer interaction and thus making mass customization more productive. Out of a pool of 118 mass customization firms and their communities, we selected representative companies (in terms of community size, - integration and openness) within an iterative approach for in-depth interviews. We found that communities can serve as levers for mass customization productivity, but companies seem to exploit them differently: Companies with a small customer base tend to limit communities merely on marketing communication to increase sales output. Providers with large and integrated communities realize a broader productivity potential from communities, exploiting them not only for increasing productivity output but for decreasing input factors in customer interaction processes (such as support in product configuration).
