This paper examines how a limit on foreign players has influenced national football in Russia. For this purpose, the effects on competition in the league, number of new young players in the national team and commercial value are investigated. Both positive and negative effects are examined. On the one hand, a quota on foreign players raised the competition in the Russian Premier League and captured attention of club owners on the development of youth academies. On the other hand, the negative effects included the reduction in the number of young players in the Russia national team, and the restriction in the invitation of international stars slowed down the growth of match attendance and commercial value. Therefore, because of the current limit, Russia became less competitive. However, if some of the measures suggested in this paper were to be implemented, Russia might improve its development of national football. 相似文献

A problem for a central crack in a plate subjected to plane strain conditions is investi-gated. Mode Ⅰ crack loading is created by a dynamic pressure pulse applied at a large distance from the crack. It was found that for a certain combination of amplitude and duration of the pulse applied, the energy transmitted to the sample has a strongly marked minimum, meaning that with the pulse amplitude or duration moving away from the optimal values, minimum energy required for initiation of crack growth increases rapidly. The results obtained indicate a possibility to optimise energy consumption of different industrial processes connected with fracture. Much could be gained in, for example, drilling or rock pounding where energy input accounts for the largest part of the process cost. Presumably further investigation of the effect observed can make it possible to predict optimal energy saving parameters, i.e. frequency and amplitude of impacts, for industrial devices, e.g. bores, grinding machines, and hence significantly reduce the process cost. The pre-diction can be given based on the parameters of the media fractured (material parameters, preva-lent crack length and orientation, etc.). 相似文献

In this paper, quantitative measures for the assessment of the hydraulic excavator digging efficiency are proposed and developed. The following factors are considered: (a) boundary digging forces allowed for by the stability of an excavator, (b) boundary digging forces enabled by the driving mechanisms of the excavator, (c) factors taking into consideration the digging position in the working range of an excavator, and (d) sign and direction of potential digging resistive force. A corrected digging force is defined and a mathematical model of kinematic chain and drive mechanisms of a five-member excavator configuration was developed comprising: an undercarriage, a rotational platform and an attachment with boom, stick, and bucket. On the basis of the mathematical model of the excavator, software was developed for computation and detailed analysis of the digging forces in the entire workspace of the excavator. By using the developed software, the analysis of boundary digging forces is conducted and the corrected digging force is determined for two models of hydraulic excavators of the same mass (around 17 000 kg) with identical kinematic chain parameters but with different parameters of manipulator driving mechanisms. The results of the analysis show that the proposed set of quantitative measures can be used for assessment of the digging efficiency of existing excavator models and to serve as an optimization criterion in the synthesis of manipulator driving mechanisms of new excavator models. 相似文献

This article focusses on the types of assistance which the universities in the western European countries could render to their peers in Eastern Europe. It explores the ways in which this aid would contribute to the elaboration of the transnational culture of the New European Home. Stress is laid on the need to integrate the educational and research activities of European universities for the training of new intellectual élites. A considerable expansion of student exchanges is suggested, particularly the training of foreign language teachers in foreign universities. The universities should rediscover and lay stress on humanism and end their participation in military research. They should prepare bachelor's and master's degree holders capable of working as teachers in other types of higher education institutions and as researchers and theorists in various types of cultural establishments. The article concludes with an examination of the scope and the operation of the International Environmental and Cultural Centre of Norway which is operated by the Byelorussian State University and the Folk High School of Agder, Norway. This centre is cited as an example of the type of inter‐university centre which should be established all over Europe so as to further the integration of European universities. 相似文献

The paper questions some of the premises in studying academic spin-offs in developed countries, claiming that when taken as
characteristics of ‘academic spin-offs per se,’ they are of little help in understanding the phenomenon in the Eastern European
countries during the transitional and post-transitional periods after 1989. It argues for the necessity of adopting a path-dependent
approach, which takes into consideration the institutional and organisational specificities of local economies and research
systems and their evolution, which strongly influence the patterns of spin-off activity. The paper provides new findings and
original arguments in support of Balazs’ seminal theses (Balazs 1995, 1996) about the emergence of academic spin-offs during the early transition. It reveals key economic and policy mechanisms bearing
on academic entrepreneurship in Eastern Europe, such as the tensions between economic and political nomenclatures of former
Communist Parties, where the dismantling or preservation of the power of political nomenclature resulted in different patterns
of development—rapid reforms in the ‘first wave’ of EU accession countries or the establishment of rent-seeking and assets-stripping
economies in countries like Bulgaria and Romania, making the transition period especially difficult. In the latter, a specific
economic environment emerged, unknown in Western Europe and in the ‘champions’ of transition—such as suppression of the authentic
entrepreneurship in a number of economic sectors, disintegration of corporate structures, etc. Thus, the paper reveals the
common ground behind the two conflicting tendencies in post-socialist academic spin-offs, partially outlined in other research
(Simeonova 1995; Pavlova 2000): as an authentic form of academic entrepreneurship grasping the opportunities opened up by the economic crisis and compensating
failures in science and technology policy on the one hand, and as specific rent-seeking strategy draining valuable public
assets on the other (the latter, in turn, boosting the negative attitudes in local scientific communities). The paper provides
new findings about the evolution of the academic spin-offs in Bulgaria along the two polar trends and their positive and negative
repercussions on parent research institutions. The results were achieved in the PROKNOW Project, EC 6th Framework Program. 相似文献

UK higher education is undergoing a period of significant change that generates a series of tensions and difficulties for universities and university leaders. This paper explores these tensions through analysis of findings from a study comprising 152 semi‐structured face‐to‐face interviews in 12 UK universities. Building on from theories of ‘distributed leadership’ in schools, five main constituent elements of leadership practice in higher education are identified (personal, social, structural, contextual and developmental) and explored to show how they shape perceptions and experiences of leadership. The paper concludes with a refined model that teases apart the multilayered nature of higher education leadership at individual, group and organisational levels. In particular, it is argued that ‘social capital’ and ‘social identity’ act as important bridges between individual agency and organisational structure and that although widely distributed, higher education leadership may be best regarded as ‘hybrid’. 相似文献

This paper outlines the activities of the Interstate Coordination Council for Scientific and Technical Information (ICCSTI),
which is aimed at coordination of the actions of states-participants of the CIS in the exchange of scientific and technical
information, for the informational support of interstate scientific and technical cooperation. It examines the strategy and
structure of information support of innovation processes as part of the innovative integration of the CIS, which is implemented
together with the formation of an integrated information environment, as well as shaping the information infrastructure of
the innovative integration of states-participants of the CIS based on the concept of scientific information to ensure programs
and projects of states-participants of CIS in the sphere of innovations. We describe a distributed multilevel system of information
support of innovation, which is designed for the integrated management of information resource sharing. 相似文献
