Fish Wars: Cooperative and Non-Cooperative Approaches

Mirman (1979) and Levhari and Mirman (1980) suggested a simple two person multistage game-theoretical model which sheds some light on the economic implications inherent in the fishing conflicts where the decisions of the competitors have an effect on the evolution of the fish population and so, on the future expected profit of the competitors. In this paper we consider a generalization of the Levhari and Mirman Fish War Game for the case of n participants of the conflict for different scenarios of hierarchical and coalition structures of countries. We derive the equilibrium and its steady-state behavior for all these scenarios and analyze the impact which the hierarchical and coalition structures can have on fishery and ecology.Nash equilibrium, multistage game, fish war game, cooperative behavior

On K-stability of P3 blown up along the disjoint union of a twisted cubic curve and a line

We find all K-polystable smooth Fano threefolds that can be obtained as blowup of projective space along the disjoint union of a twisted cubic curve and a line

The New Aesthetics and Traditions of the Russian Stone and Jewellery Art in the Collections of Yekaterinburg Jewellery Houses

This article presents a review of the leading jewellery companies in Yekaterinburg. We present a comparative analysis of the range of products, focussing on the new stylistic design techniques and technological features of the jewellery collections and stone-cutting works produced by the leading jewellery houses. Examples of the most significant works in the premium class segment are discussed. We demonstrate how modern Russian jewellery art creatively combines and develops Russian and European historical jewellery tradition while striving to absorb and utilize cutting-edge techniques, materials and technologies. The wide range of resulting artworks and approaches to modern jewellery-making highlights the successful combination of historical and modern approaches. More sophisticated technology allows the jewellery artists to implement new ideas while creating increasingly technically complex works. We analyse the works by the leading Yekaterinburg jewellery houses: MOISEIKIN, CHAMOVSKIKH, Natasha Libelle, Ringo, Maxim Demidov, Jewellers of Ural. Keywords: jewellery collection, design, translation method, quatation method, transformatio

Institutional corruption in Russian universities

Russia is about to become an academic superpower, which makes it very successful at least in the context of the BRIC countries—Brazil, Russia, India, China. After various effective reforms, including the Bologna process and the modernization of admissions procedures, the Russian government is now working hard on remedying corruption in higher education

K-stable smooth Fano threefolds of Picard rank two

We prove that all smooth Fano threefolds in the families 2.1, 2.2, 2.3, 2.4, 2.6 and 2.7 are K-stable, and we also prove that smooth Fano threefolds in the family 2.5 that satisfy one very explicit generality condition are K-stable.Comment: 63 page

An experimental evaluation of an anti-corruption intervention among Ukrainian university students

In this paper, we investigate experimentally the effect of an anti-corruption intervention -an info folder based on materials developed by Transparency International- on Ukrainian university students’ willingness to participate in an anti-corruption campaign and their general attitude toward corruption. In a survey of 600 students in the Ukrainian city of Lviv, individuals were randomly exposed to either the anti-corruption folder (treatment group) or a folder with information about Lviv (control group). The results suggest that students who have previous experience with bribing are more open to the campaign, while the effect on the total sample is not statistically significant. Furthermore, the intervention increases the overall perception that corruption is a (long-term) part of society rather than a temporary phenomenon. Finally, students with experience in corrupt practices tend to adopt a more negative view of corruption. For those without such experiences, however, we find some indication that the treatment could bolster the acceptance of corruption by instructing the students about its dissemination. The effects of this intervention are therefore ambivalent and appear to depend on the students’ previous exposure to corruption

Managing Business Corruption: Targeting Non-Compliant Practices in Systemically Corrupt Environments

This article focuses on strategies of ‘managing business corruption’ at the firm level and offers insights for practitioners in systemically corrupt environments. Our study of 110 CEOs and owners of companies operating in Russia tested a new, ethnographic approach to managing corruption at a firm level. We conceptualize ‘managing business corruption’ as devising and implementing strategies that mitigate corruption-related risks in an effective way. We argue that such strategies have to target specific non-compliant practices, identified bottom-up, yet also amount to a pragmatic, problem-solving framework at the firm level, implemented top-down. Leadership is a key factor which defines effectiveness of corruption management in systemically corrupt environments. While the latter are generally conducive to tolerance and passive attitudes to corruption among business leaders, we identify proactive modes (preventive and controlling) and possible channels (formal hierarchy and informal networks) for leadership action. The proposed approach can also be used for leadership training

Korruption und informelle Praktiken im russischen Geschäftsleben: Fallbeispiele aus der Sicht ausländischer Unternehmer

Korruption wird als eines der größten Hindernisse für die Wirtschaftsentwicklung und auch für die Tätigkeit ausländischer Investoren in Russland angesehen. Zentrale Probleme sind in diesem Zusammenhang die selektive Anwendung von Recht, die Unsicherheit von Eigentumsrechten, die Belastung durch Bestechungszahlungen und die Abhängigkeit von Netzwerken. Zu beachten ist aber auch, dass Korruption im russischen Kontext teilweise mit gesellschaftlichen Fragen wie der sozialen Verantwortung von Unternehmen verknüpft wird
