Evaluating the risk of patent infringement by means of semantic patent analysis: the case of DNA chips

In this paper, we are going to present a method for detecting the risks of patent infringement by evaluating similarities between patent documents on the basis of semantic patent analysis. This approach enables the user to visualize similarities in the contents on a semantic patent map by means of multi‐dimensional scaling. The effectiveness of the semantic patent map has already been demonstrated by Dressler (2006) with regard to patents of seal technology, in which documents are commonly kept short and the extracted contents are concise. This paper will open out to the field of biotechnology, where patents can easily comprise several hundreds of pages. The method presented here conveys an interdisciplinary approach and combines computer‐aided natural language processing with domain‐specific expertise of biochemical processes. This is illustrated by an authentic case of infringement involving two manufacturers of DNA chips. Our experiment will show how the infringement case is visualized on a patent map based on semantic patent analysis. This experiment can be compared with the search for a needle in a haystack, the two competitive patents representing significantly conflicting ‘needles.’ From an approximate number of 4,000 patents in the current US Class 435/6, a set of patents was selected that included the ‘needles’ mentioned. This paper will point out how such mutual interference can be detected by way of semantic patent analysis, and what advice may be given to R&D managers who are faced with the risk of patent infringement.     

Cognitive,Emotional, and Sociocultural Processes in Consumption

This article examines deliberative, emotional, and sociocultural processes in consumption. The authors draw upon basic processes from two leading theories in social psychology, the theory of planned behavior (TPB) and the model of goal‐directed behavior (MGB), to develop a comprehensive approach to decision making more appropriate for many consumption decisions, and revise the representation and modeling of key variables to better reflect how social psychological processes relate to consumer behavior. A survey was conducted among real adult consumers of bacalhau in Portugal. Because it is most common for women to prepare bacalhau meals in Portugal, 153 female participants were recruited for this survey. The results show that the TPB, and especially the MGB, are found to explain food consumption decisions well but only after the approaches are modified in form and content to accommodate the complex emotional and social aspects of the consumption context. The results also show that the effects of key determinants of desire in the MGB are contingent on the traits of food involvement and cultural orientation (i.e., degree of vertical individualism). The approach taken herein overcomes limitations of existing theories by synthesizing relevant processes across two leading theories and by introducing new variables and processes, thereby showing that the organization of these processes and their contingency on cultural variables regulate consumption.     

ERP On Demand Platform

Platforms for SaaS-based enterprise applications are prospering and the number of on-demand ERP vendors is increasing. We combine both phenomena for the first time and illustrate how the integration of a sustainability benchmarking service into an on-demand ERP platform provides added value beyond pure cost savings. By applying a qualitative system dynamics approach we identify self-reinforcing mechanisms which allow a faster and more comprehensive market penetration compared to providing these services separately.

Energiewende: Alles eine Frage der Partizipation? Governance-Herausforderungen zwischen Zentralität und Dezentralität

The interaction of centralised and decentralised elements is not only a challenge for the technical und functional implementation of the energy transition, but also for the political and social assignment of developing adequate governance strategies for future energy systems. While “participation” is of capital importance for all governance approaches mediating centralising and decentralising trends, it is far from clear, how participation is to be realized in order to promote energy transition and avoiding pitfalls and flaws of participative decision making processes. Against the backdrop of a multi-dimensional understanding of “participation” comprising procedural, factual, legitimatory and meta-reflective functions, the paper considers the tense relations of participation and efficiency, legitimacy and professionalized expertise, thereby identifying structural challenges for participation in democratic societies. Finally, some suggestions are made, how the governance of the energy transition can be shaped in the future.     

Revealed comparative advantages in Greece, Ireland, Portugal and Spain

Greece, Ireland, Portugal and Spain were all hit by the economic downturn in the course of the financial crisis and have been struggling with national debt crises and recession. A problem common to all of these countries is the collapse of national demand. Foreign trade might seem a logical way to restore economic strength, but little is known about the international competitiveness of these countries’ industries. This paper sheds light on their export structures using the revealed comparative advantage indicator.     

Qualitätserwartungen,Qualitätswahrnehmungen und die Nutzung von Fernsehserien

Ziel des Beitrags ist die Beantwortung der Frage, welche Faktoren die Nutzung von Fernsehserien erkl?ren k?nnen. Kann sie im Wesentlichen auf Habitualisierung und strukturelle Rahmenbedingungen zurückgeführt werden, oder l?sst sie sich dadurch erkl?ren, dass die Erwartungen an die Qualit?t von Fernsehserien und die Wahrnehmung von Qualit?tseigenschaften der verschiedenen Serien zwischen den Rezipienten variieren? Zun?chst werden die theoretisch relevanten Faktoren für ein Modell der subjektiven Qualit?tsauswahl identifiziert und operationalisiert. Anschlie?end wird in einer empirischen Studie geprüft, ob diese Faktoren einen Einfluss auf die Nutzung der Fernsehserien haben. Die Untersuchungsergebnisse zeigen, dass die drei Elemente des theoretischen Ansatzes — Qualit?tserwartungen, Qualit?tswahrnehmungen und Qualit?tsurteile — die Seriennutzung zu einem betr?chtlichen Teil erkl?ren k?nnen. Der Vorteil dieses Ansatzes gegenüber dem Uses and Gratifications Approach besteht darin, dass die Eigenschaften des Angebots im Mittelpunkt stehen. Damit wird es m?glich, Aussagen darüber zu machen, welche wahrgenommenen Merkmale des Angebots für die Nutzungsentscheidungen der Rezipienten relevant sind.     

Cost information sharing with uncertainty averse firms

Summary. A homogeneous Cournot duopoly with asymmetric information is analyzed. Every firm learns its own marginal cost parameter, but not the marginal cost parameter of the opponent. Every firm can commit to revealing its private information to the other firm, i.e. to share information. The influence of uncertainty aversion on the readiness of the duopolists to share cost information is analyzed. Uncertainty aversion is modeled according to the Choquet utility theory. It is shown that low uncertainty aversion leads the firms to share information, while high uncertainty aversion leads the firms not to share. A simple economic explanation for this result is given.Received: 5 January 2001, Revised: 7 May 2003, JEL Classification Numbers: D43, D81, D82.I wish to thank Jürgen Eichberger, Volker Krätschmer, Willy Spanjers, seminar participants at Universität des Saarlandes, seminar participants at University College London, participants in the conference of the Verein für Socialpolitik in Mainz 1999 and an anonymous referee for helpful comments.

The end of the Ghent system as trade union recruitment machinery?

During the past 15 years, membership rates in many unions have been declining in Denmark, Finland and Sweden. Reasons for this decline may be similar to what has happened in other countries—occupational change and neoliberal ideology and policies—but in the three Ghent countries, changes in the unemployment insurance system may also have affected trade union membership losses. The major part of the decline has taken place in a period of low unemployment, which may have reduced the employee incentive to take unemployment insurance, but will increasing unemployment rates mean more trade union members? At least for the LO‐ and SAK‐affiliated trade unions, it seems that trade union independent unemployment funds may be alternatives for workers who take unemployment insurance.
