Uncertainties in discourses of consulting. Why consultees need philosophy — pragmatism for exampleThe author demonstrates, in which way the pragmatism, particularly the philosophy of John Dewey with his aspects of epistemology, theory of acting, theory of learning, theory of democracy and ethics, can help, how people in organisations can learn to act intelligently and successfully in processes of consulting, although just today uncertainties are wide-spread.     

European cultures and management styles

After the establishment of the Common Market in Europe, many companies from abroad opted for a single European headquarters and searched for European managers. That leads to the question whether one can really speak of a common European management style. The article at hand examines this issue. To do this, the legal framework and Corporate Governance background of individual European countries are assessed. Furthermore, cultural differences in Europe are considered. Referring to studies of cultural dimensions in European countries, the authors propose five different cultural areas in Europe. This leads to a concluding discussion of management styles in these regions.     

Benchmarking Safety Climate in Hazardous Environments: A Longitudinal, Interorganizational Approach

Safety climate is an important element of organizational reliability. This study applied benchmarking strategies for monitoring safety climate across nine North Sea oil and gas installations that were surveyed in consecutive years. Examination of absolute changes in safety climate complemented the benchmarking approach. Discriminant function analyses (DFA) identified the elements of safety climate predictive of self-reported accidents; correlational analyses were applied to the scale scores and accident proportions across the year period. Absolute improvements were substantial, with safety climate profiles converging in the second year. Large relative improvements were also observed. DFA highlighted perceived management commitment to safety and willingness to report accidents as significant predictors of personal accident involvement. Changes in perceived management commitment to safety were closely associated with changes in safety behavior.     

Integrated Direct and Indirect Flood Risk Modeling: Development and Sensitivity Analysis

In this article, we propose an integrated direct and indirect flood risk model for small‐ and large‐scale flood events, allowing for dynamic modeling of total economic losses from a flood event to a full economic recovery. A novel approach is taken that translates direct losses of both capital and labor into production losses using the Cobb‐Douglas production function, aiming at improved consistency in loss accounting. The recovery of the economy is modeled using a hybrid input‐output model and applied to the port region of Rotterdam, using six different flood events (1/10 up to 1/10,000). This procedure allows gaining a better insight regarding the consequences of both high‐ and low‐probability floods. The results show that in terms of expected annual damage, direct losses remain more substantial relative to the indirect losses (approximately 50% larger), but for low‐probability events the indirect losses outweigh the direct losses. Furthermore, we explored parameter uncertainty using a global sensitivity analysis, and varied critical assumptions in the modeling framework related to, among others, flood duration and labor recovery, using a scenario approach. Our findings have two important implications for disaster modelers and practitioners. First, high‐probability events are qualitatively different from low‐probability events in terms of the scale of damages and full recovery period. Second, there are substantial differences in parameter influence between high‐probability and low‐probability flood modeling. These findings suggest that a detailed approach is required when assessing the flood risk for a specific region.     

Effect of Climate Change on the Concentration and Associated Risks of Vibrio Spp. in Dutch Recreational Waters

Currently, the number of reported cases of recreational‐ water‐related Vibrio illness in the Netherlands is low. However, a notable higher incidence of Vibrio infections has been observed in warm summers. In the future, such warm summers are expected to occur more often, resulting in enhanced water temperatures favoring Vibrio growth. Quantitative information on the increase in concentration of Vibrio spp. in recreational water under climate change scenarios is lacking. In this study, data on occurrence of Vibrio spp. at six different bathing sites in the Netherlands (2009–2012) were used to derive an empirical formula to predict the Vibrio concentration as a function of temperature, salinity, and pH. This formula was used to predict the effects of increased temperatures in climate change scenarios on Vibrio concentrations. For Vibrio parahaemolyticus, changes in illness risks associated with the changed concentrations were calculated as well. For an average temperature increase of 3.7 °C, these illness risks were calculated to be two to three times higher than in the current situation. Current illness risks were, varying per location, on average between 10^?4 and 10^?2 per person for an entire summer. In situations where water temperatures reached maximum values, illness risks are estimated to be up to 10^?2 and 10^?1. If such extreme situations occur more often during future summers, increased numbers of ill bathers or bathing‐water‐related illness outbreaks may be expected.     

Robust Resource Allocation Decisions in Resource‐Constrained Projects*

The well‐known deterministic resource‐constrained project scheduling problem involves the determination of a predictive schedule (baseline schedule or pre‐schedule) of the project activities that satisfies the finish–start precedence relations and the renewable resource constraints under the objective of minimizing the project duration. This baseline schedule serves as a baseline for the execution of the project. During execution, however, the project can be subject to several types of disruptions that may disturb the baseline schedule. Management must then rely on a reactive scheduling procedure for revising or reoptimizing the baseline schedule. The objective of our research is to develop procedures for allocating resources to the activities of a given baseline schedule in order to maximize its stability in the presence of activity duration variability. We propose three integer programming–based heuristics and one constructive procedure for resource allocation. We derive lower bounds for schedule stability and report on computational results obtained on a set of benchmark problems.     

Governance of open source software: state of the art

In this overview of governance mechanisms developed within open source software (OSS) circles, three types of governance are studied: ‘spontaneous’ governance, internal governance, and governance towards outside parties. Moreover, two main ways in which lessons from OSS can be applied elsewhere are explored: peer production of products other than software, and embedding ‘peer-produced’ products and peer processes into existing institutions (‘coupling’).

Understanding Consumer Confidence in the Safety of Food: Its Two-Dimensional Structure and Determinants

Understanding of the determinants of consumer confidence in the safety of food is important if effective risk management and communication are to be developed. In the research reported here, we attempt to understand the roles of consumer trust in actors in the food chain and regulators, consumer recall of food safety incidents, consumer perceptions regarding the safety of particular product groups, personality characteristics, and sociodemographics, as potential determinants of consumer confidence in the safety of food. Consumer confidence in the safety of food was conceptualized as consisting of two distinct dimensions, namely, "optimism" and "pessimism." On the basis of a representative sample of 657 Dutch consumers, structural equation modeling was applied to simultaneously estimate the effect of the determinants on both "optimism" and "pessimism." The results indicated that, to a considerable extent, both optimism and pessimism about the safety of food arise from consumer trust in regulators and actors in the food chain and the perceived safety of meat and fish rather than other product categories. In addition, support was found for the notion that optimism and pessimism are conceptually distinct, as these dimensions of confidence were partly influenced by different determinants. The results of this study imply that consumer confidence in the safety of food could be enhanced by improving both consumer trust in societal actors, and consumer safety perceptions of particular product groups.     

Reluctant Reforms: The Case of Kazakhstan

This paper investigates what happens during reluctant reforms in which normative imperatives conflict with self-interest. In the literature one of the expected outcomes is hypocrisy. However, the claim of hypocrisy is a strong one and needs backing. The purpose of this paper is to investigate on the basis of which indicators such claims can be warranted and whether these indicators are found in the case of reforms in the Republic of Kazakhstan. The common thread in the literature about hypocrisy is the point of inconsistency. Inconsistency in two ways: in the case of reforms to claim to induce huge changes, while resulting in nominal reforms, not changing anything; and inconsistency in the reactions to and opinions about such changes showing ‘differential judgments according to contexts’. This is investigated for the reforms in Kazakhstan with regard to promoting democracy and protecting human rights during the last decade. The analysis argues that these reforms as well as the international reactions do possess all the elements indicative for hypocrisy. At the end the implications for research on reforms are discussed.
