Cooperation between firms is often addressed from the perspective of relationship organizing; however, we know little about people’s working-level engagement in collective action during interfirm projects. Focusing on cooperation between rival firms (coopetition), this paper explores how knowledge can be shared among participants. We conduct a case study of a joint-project team composed of staff from rival firms. Using the principles of grounded theory, we identify four distinct modes of knowledge sharing. By interpreting these modes in terms of temporalities and influential social structures, we develop an understanding of how individual engagement promotes knowledge sharing in an inter-firm coopetitive project. The study reexamines emerging orientations (cooperation and competition) according to institutional logics (market, corporation, and community) and temporalities. It also offers insight into the management of inter-organizational projects that are viewed as temporary organizations. [less ▲]

Recently, Christoffersen et al. (2013) argue that the overreaction puzzle of Stein (1989) can be explained by a variance-dependent pricing kernel. In this note, we challenge this view. Our theoretical results are in line with their argument that the variance under risk-neutral measure is more persistent than the variance under physical measure due to a negative variance risk premium. But our results do not support their argument that the more persistent variance is able to qualitatively explain Stein’s findings. We show theoretically that the persistence of the volatility cannot amplify the movements of long-term variance to short-term fluctuations in variance, and, therefore, conclude that Stein’s overreaction puzzle is still unsolved.

Dieser Beitrag rekonstruiert den Einfluss der Hochschulentwicklung und der wissenschaftlichen Kapazitätsbildung auf die wissenschaftliche Wissensproduktion in Deutschland, einem der weltweit stärksten Produzenten wissenschaftlichen Wissen seit 1900. Folgende Forschungsfragen sollen beantwortet werden: Wie haben institutionalisierte Strukturen, und darin verschiedene Organisationsformen, die langfristige Entwicklung wissenschaftlicher Produktivität beeinflusst und verändert? In welchen organisationalen Netzwerken entwickelt sich aktuell die Wissenschaft weiter? Die Annäherung an den Forschungsgegenstand erfolgt auf der Makroebene anhand von Indikatoren zur Erfassung der globalen Expansion, Kooperation und Produktion der Wissenschaft. Vor dem Hintergrund dieses Untersuchungsrahmens wird dann auf der Mesoebene das Zusammenspiel von Organisationsformen in Deutschland mittels netzwerkanalytischer Verfahren betrachtet. Ziel des Beitrags ist, die Orte und institutionellen Settings wissenschaftlicher Produktion zu identifizieren und anhand ihrer Aufgaben und Ziele voneinander abzugrenzen sowie ihre Beziehungen zueinander herauszuarbeiten. Als theoretische Basis werden neo-institutionalistische Ansätze zur Untersuchung und Erklärung der Expansion des Hochschulwesens und der Wissenschaft und zur Analyse von organisationalen Netzwerken herangezogen. Grundlage der empirischen Analyse bilden Publikationen in peer-reviewed Zeitschriften als Kennzeichen wissenschaftlicher Produktion. [less ▲]

Many older people have functional limitations. One possibility to overcome these limitations is assistive technology (AT), but their usage rate is still low. Existing models of AT use provide some insight into possible reasons for use and non use of ATs, but the predictive value of these models in samples of older people is modest. This could be due to a neglect of relevant reasons in the predictor sets. To find further predictors we performed a systematic literature search in Google Scholar, MEDLINE, and PsycINFO databases and – applying an action-theoretical approach – a meta-synthesis of seven qualitative studies about older people´s reasons for use or non-use of ATs. We found 25 reasons referring to user´s beliefs and desires (e.g., about demand, act of using ATs, its consequences) of which 18 were not contained in existing AT use models. More of these reasons referred to the non-use than to the use of ATs. Some reasons generalized across ATs (e.g., perceived unreliability), whereas others (e.g., privacy concerns, desire to avoid burden to others) appeared specific to tele-alarm or smart home technology. We suggest integrating the newly identified reasons as additional predictors in existing AT use models to arrive at a more comprehensive model with improved predictive value and increased practical usefulness for developmental counseling.

Screening powers of arbitral institutions over requests initiating investment arbitrations are often justified by the need to prevent embarrassment of states and to avoid unnecessary costs. This Chapter examines possible effects of such powers, particularly on the arbitral development of the jurisdictional standards governing investment arbitration. Can administrative organs filter the demands for legal change that will be heard before tribunals, and if so, does this diminish the legitimacy of their screening powers? It is argued that screening powers offer possibilities of setting arbitrators’ agenda in terms of which demands for legal change will be considered. This could affect their legitimacy, but it does not mean that screening powers have completely lost their justification. It is suggested that such powers must be exercised with an extreme level of diligence, requiring an almost complete elimination of legal considerations, in order to safeguard their legitimacy.

Regional foreign banks expanded quickly over the past decade in developing and emerging countries and have a growing influence in banking systems. We question whether the development of African regional foreign banks, also called Pan-African banks, influences financial inclusion of firms and households. To this end, we combine the World Bank Global Findex database and the World Bank Enterprise Surveys with a hand-collected database on the presence of regional foreign banks. We find that Pan-African banks presence increases firms’ access to credit and limited evidence that they favor financial access of the middle class by restoring confidence in banks. We suggest that this impact is related to the adoption of an aggressive strategy aiming at gaining market shares rather than through the exploitation of informational and technological advantages.

The aim of this chapter is to highlight the different issues that one faces when trying to ensure the fundamental right to data protection of blockchain users. The provisions of the General Data Protection Regulation are used as an example of the difficulties. Here, two principal issues are addressed: issues regarding the addressees of the General Data Protection Regulation's provisions and issues regarding the qualification and treatment of data available on permissionless and permissioned blockchains. Finally, this article highlights the consequences that these uncertainties may have on the protection of users’ fundamental rights and the necessity to ensure legal certainty through additional guidance from the European legislator or upcoming case-law.

In the light of the recently renovated interest in returning humans to the Moon, this paper addresses the main legal challenges related, with the goal to show practical solutions under the current system of international space law. In order to do so, the paper first presents an overview of current lunar exploration programs, arguing that public and private missions raise different challenges and thus require specific models. Following, it accordingly assesses possible legal solutions for the regulation of these programs. On the one hand, States’ exploration programs may be governed by a revised version of the Intergovernmental Agreement already concluded for the International Space Station. On the other hand, private activities could be better organized relying on Articles VI-IX OST as integrated by a new UNGA Resolution, ad hoc bilateral agreements and specific provisions in national space legislations. Finally, the paper concludes underlining the importance of international cooperation as the key to ensure the peaceful use and exploration of outer space. [less ▲]
