Anspruch und Wirklichkeit eines Beziehungsberufes Eine Analyse von Verbands-und Fachzeitschriften der Supervision

The debate on the professionalisation and development of the Counselling/Supervision field is considered. An analysis of the major professional journals shows that the focus of attention is on the expansion of the profession into new fields, as more and more Counsellers/Supervisors are working in the profit sector. However, the new experiences gained there are not to be found among the published articles and the debate continues without considering actual facts. The central claim is that members of a profession that defines itself through reflective thought, are indeed not reflecting on their own profession and position.

Buying used products for remanufacturing: negotiating or posted pricing

Product reclamation is a critical process in remanufacturing. It is generally assumed in the literature that customers simply want to get rid of their used products without expecting any compensation for them. Some authors have only recently started looking into firms that offer a posted (fixed) price for them. Following recent reports suggesting that customers are increasingly open to bargaining, we compare using a posted price and bargaining to obtain used products. In our analysis, we consider an original manufacturer acting as a monopolist as well as a manufacturer and an independent remanufacturer acting in a duopoly. We analytically show that bargaining is always beneficial to the monopoly manufacturer. In the duopoly case, we distinguish a Cournot competition and a market with the manufacturer as Stackelberg leader. The results of a numerical study show that both firms will use posted pricing in the Cournot competition, especially if bargaining is not costless. By contrast, the remanufacturer can significantly increase his profit by using negotiations if he is the Stackelberg follower.     

Perceptions of Legitimacy in Nordic Regional Development Networks

This article examines actors’ views on legitimacy in governance networks in four Nordic countries. The analysis is based on a survey of similar regional development networks in Denmark, Norway, Sweden and Finland. The countries form a continuum, in which the connection between legitimacy and representative democracy is strongest in Denmark and weakest in Finland. Norway and Sweden fall in between the two. Not only the strength, but also the form of the connection, and the weight given to it vary among the countries. Article contributes to the debate on democracy in network governance.     

A Branch and Cut solver for the maximum stable set problem

This paper deals with the cutting-plane approach to the maximum stable set problem. We provide theoretical results regarding the facet-defining property of inequalities obtained by a known project-and-lift-style separation method called edge-projection, and its variants. An implementation of a Branch and Cut algorithm is described, which uses edge-projection and two other separation tools which have been discussed for other problems: local cuts (pioneered by Applegate, Bixby, Chvátal and Cook) and mod-k cuts. We compare the performance of this approach to another one by Rossi and Smiriglio (Oper. Res. Lett. 28:63–74, 2001) and discuss the value of the tools we have tested.     

Pluralism in Project Management: Navigating the Crossroads of Specialization and Fragmentation

Project management is a rapidly expanding subfield of management and organization studies. This paper seeks to make sense of this development and the current state of project management research. It reviews the literature published over the last five decades in 30 leading management and organization journals. In total, 305 articles were included in the data set. The paper proposes a categorization of the published articles into seven ‘schools of thought’: Optimization School, Factor School, Contingency School, Behaviour School, Governance School, Relationship School and Decision School. The schools vary in terms of their main focus and use of the project concept, major research questions, methodological approaches and type of theorizing. It is suggested that a better awareness on how to make use of the schools and the identified perspectives would stimulate cross‐fertilization, unification and thus enhance a pluralistic understanding of projects and project management at the same time as it would prepare research to frame more accurately the problems of contemporary projects. In that respect, the paper offers ideas on how to navigate at the crossroads between specialization and fragmentation, between the search for novel topics and improvements of existing knowledge.     

Will this voluntary project be successful?: Validation of an instrumental model of volunteering behavior

This study examines whether instrumental considerations influence people's decision to start volunteering. Using social dilemma theory as a basis, the authors assume that the decision to start volunteering is contingent on whether a voluntary program will be successful in achieving a collective goal. The study's findings underscore the importance of anticipated success likelihood perceptions, which appear to have a major impact on potential volunteers' decision‐making process. Furthermore, social consensus beliefs relating to proximate referents have a more distinct impact than do social consensus beliefs relating to distant referents. Finally, the study reveals interesting gender‐specific differences. On the basis of the results from the empirical analysis, the study offers implications for management and avenues for further research.
