The Climate Policy of the European Union

There is now almost universal agreement that climate change, with potentially disastrous consequences, is happening and that it is contributed to by human activities. This Forum is dedicated to the discussion of various aspects of the European Union's climate policy, e.g. the EU's future role in the global effort to combat global warming, the efficiency of its climate strategy, the design of a new rule for sharing the corresponding burdens fairly among member states, and the interrelationships between the Union's climate policies, on the one hand, and its energy and transport policies, on the other. * and member of the German Advisory Council on Global Change (WBGU).

ENERGY EFFICIENCY EVALUATION IN MANUFACTURING THROUGH AN ONTOLOGY‐REPRESENTED KNOWLEDGE BASE

Improving energy efficiency in a manufacturing company through an energy management system requires active participation of different stakeholders and involvement of different organizational entities and technical processes. Interoperability of stakeholders and entities is the key factor to achieve a successful implementation of an energy management system. Researchers have been developing approaches in applying ontologies to address interoperability issues among humans as well as machines. Ontologies have also been used for knowledge representation in different domains, such as energy management and manufacturing. In recent years, researchers have developed knowledge‐based intelligent energy management systems in buildings, especially households, which use ontologies for knowledge representation. In the manufacturing domain, ontologies have been used for knowledge management in order to provide a common formal understanding between the stakeholders, who have different background knowledge. This paper proposes an approach to apply ontology to allow knowledge‐based energy efficiency evaluation in manufacturing companies. The ontology provides a formal knowledge representation that addresses the interoperability issues due to different human stakeholders as well as machines involved in the energy management system of the company. This paper also describes the methods used to construct and to process the ontology. Copyright © 2013 John Wiley & Sons, Ltd.     

Statistic problems regarding tuberculosis infection and morbidity of tuberculosis

The statistic relations between tubercular infection and morbidity are comparatively complicated, partly because the infection rate will depend on age and calendar time, partly because of the varying interval (latent period) which may pass from the time of infection to the disease. A theoretical analysis of these relations may possibly count on a certain amount of interest to future statistic investigations regarding tuberculosis. It is my opinion that too little attention lias been paid to them in many of the investigations which have hitherto been carried out.     

Wissenstransfer in der Betriebswirtschaftslehre: Eine Untersuchung anhand ausgewählter akademischer Zeitschriften in Deutschland und Frankreich

Reviewing and analyzing new research outcomes are important prerequisites for scientific progress. If one interprets science as a universal pursuit of knowledge development, transparency and communication between national scientific systems are indispensable in order to realize international knowledge transfer and diffusion. This article examines on the basis of scientific journals in business administration in Germany and France how and to what extent such a transfer is currently taking place. The results show a high degree of isolation.     

Strategy,political regulation and management control in the public sector: Institutional and critical perspectives

This paper mobilizes institutional and critical theories in examining how evolving management control practices, inspired by the balanced scorecard, mediated the process of strategy formation in a Swedish central government agency. Particular attention is paid to how this process was conditioned by external, political regulation of the organization. Contrary to popular conceptions of strategy and strategic management as emerging alternatives to political regulation in the public sector, the study shows how the meaning of the notion of strategy became intricately intertwined with government regulation. Whilst this affirms the tendency of organizations to comply with institutional pressures exerted by dominant constituencies, the analysis also shows how the unfolding strategy discourse gradually narrowed the meaning of the notion of strategy permeating the organization. The extension of an institutional perspective to incorporate more critical insights highlights how this process fostered some “unintended” consequences with a detrimental impact on organizational practices aimed at achieving broader social objectives. In so doing, I draw attention to how the unobtrusive power of evolving strategy discourses conditions conceptions of organizational performance and relevant constituent interests. The implications for future management accounting research combining institutional and critical theories are discussed.     

A note on the connection between factorial series distribution and zero-truncated power series distribution

Summary

The main purpose of this note is to call attention to the close relationship between the problem of estimating the parameter of a zero-truncated power series distribution and the problem of estimating the parameter of an associated factorial series distribution. We also extend a known recurrence property for the Poisson case to the binomial and negative binomial cases.     

Optimal Experimentation in a Changing Environment

This paper studies optimal experimentation by a monopolist who faces an unknown demand curve subject to random changes, and who maximizes profits over an infinite horizon in continuous time. We show that there are two qualitatively very different regimes, determined by the discount rate and the intensities of demand curve switching, and the dependence of the optimal policy on these parameters is discontinuous. One regime is characterized by extreme experimentation and good tracking of the prevailing demand curve, the other by moderate experimentation and poor tracking. Moreover, in the latter regime the agent eventually becomes "trapped" into taking actions in a strict subset of the feasible set.     

Regional currency arrangements in North America

Choosing an exchange-rate regime is largely a matter of choosing the variables that will bear the brunt of adjustment to shocks and disturbances. Floating rates, supported by inflation-targeting regimes of varying degrees of transparency, have dominated currency arrangements in North America, especially after the peso crisis of 1994. Although the member countries have pursued their policy goals without formal coordination, their objectives have been very similar. Meanwhile, de facto integration of the three economies has continued, especially in the realm of cross-border production sharing. The result has been reduction of asymmetries and convergence of business cycles, as well as changes in balance of payments behavior and in the sensitivity of trade to the exchange rate. This paper explores the implications for monetary union.     

Randomized decision rules in voting games: a model for strict proportional power

The concept of strict proportional power is introduced, as a means of formalizing a desire to avoid discrepancy between the seat distribution in a voting body and the actual voting power in that body, as measured by power indices in common use. Proportionality is obtained through use of a randomized decision rule (majority rule). Some technical problems which arise are discussed in terms of simplex geometry. Practical implications and problems in connection with randomized decision rules are indicated.
