Asymmetrical bargaining in the conference on security and cooperation in Europe

Bargaining relationships in formal international conferences and negotiations may involve structural asymmetries. A comprehensive analysis of these asymmetries in bargaining may be found in a synthesis of literature from formal game theory, structural-manipulative approaches to bargaining, social psychology, and the study of political influence. Propositions based on this literature focus on two factors which are likely to contribute to asymmetrical outcomes in negotiations: unequal costs to the negotiators from the failure to agree, and unequal resources available to employ in bargaining or influence attempts. An analysis of bargaining in the section of the Conference on Security and Cooperation in Europe (CSCE) dealing with the issues of European security gave qualified support to these propositions. Influence over the final text in the CSCE agreement is related to a rough index of losses which would have resulted for individual nations from the failure to reach agreement in the CSCE. In addition, influence over the final text is related to each nation's resources, especially military resources. More significantly, the two superpowers exerted considerable asymmetrical influence over what was not included in the CSCE agreement, thus exercising a substantial veto. Thus, the asymmetrical outcomes within the CSCE negotiations were reflective of both differences in "threat potential,” that is, in the losses which actors would receive if no agreement had ensued, as well as differences in resource

Научный миф как основа современного научно-популярного текста

Статья посвящена описанию научного мифа и особенностей его языкового представления в научно-популярных текстах. Основное внимание уделяется значению научного знания в жизни современного человека, особенностям формирования и бытования этого научного знания в общественном сознании. Основной проблемой при восприятии научного знания обычным человеком названа проблема сложности, специализированности научного языка. Научно-популярный подстиль рассматривается как основной способ популяризации научного знания и создания научного мифа. Особенностью современного научного знания является процесс его мифологизации, который осуществляется в языке.

Posibles consecuencias del cambio climático global en bosques de Lago Puelo

p.79-87Se caracteriza topoclimáticamente los habitats del bosque mixto de coihue (Nothofagus dom beyi) y ciprés (Austrocedrus chilensis), del mixto con especies valdivianas y del de lenga (Nothofagus pumilio) en el Parque Nacional y Reserva Estricta Lago Puelo. Se analiza la posible consecuencia del cambio climático en la distribución y composición de dichos bosques. De mantenerse las tendencias que en la actualidad se observan para la temperatura y la precipitación, el clima en el año 2030 sería más húmedo, más frío en el invierno y más caluroso en el verano. La vegetación debería sufrir cambios para alcanzar un nuevo equilibrio, el cual tentativamente favorecería a la lenga y a especies higrófilas como Pilgerodendron uviferum, Fitzroya cupressoides, Lama apiculata y Myrceugenia exsucca

Targeted gene expression profiling in European sea bass (Dicentrarchus labrax, L.) follicles from primary growth to late vitellogenesis

7 páginas, 6 figuras, 1 tabla como material suplementario.A real-time PCR-based gene expression survey was performed on isolated European sea bass follicles from primary growth to late vitellogenesis. Expression levels of 18 transcripts with demonstrated relevance during oogenesis, encoding gonadotropin, thyrotropin, estrogen, androgen, and vitellogenin receptors, steroidogenesis-related as well as growth and transcription factors were measured. Primary oocytes showed high mRNA levels of insulin-like growth factors 1 and 2, bone morphogenetic protein 4, estrogen receptor 2b, androgen receptor b, and SRY-box containing gene 17 together with low transcript amounts of gonadotropin receptors. Follicles at the lipid vesicles stage (i.e., the beginning of the secondary growth phase) showed elevated mRNA amounts of follicle stimulating hormone receptor (fshr) and anti-Mullerian hormone. Early-to-mid vitellogenic follicles showed high mRNA levels of fshr and cytochrome P450, family 19, subfamily A, polypeptide 1a while mid-to-late vitellogenic follicles expressed increasing transcript amounts of luteinizing hormone/choriogonadotropin receptor, steroidogenic acute regulatory protein, and estrogen receptors 1 and 2a. The molecular data presented here may serve as a solid base for future studies focused on unraveling the specific mechanisms orchestrating follicular development in teleost fish.Funding for the present work was provided by the Spanish Ministry of Education and Science to F.P through the grant AGL2007-61192/ACU.

A hydrodynamic study of the circumstellar envelope of alpha Scorpii

Context: Both the absolute mass-loss rates and the mechanisms that drive the mass loss of late-type supergiants are still not well known. Binaries such as alpha Sco provide the most detailed empirical information about the winds of these stars. Aims: The goal was to improve the binary technique for the determination of the mass-loss rate of alpha Sco A by including a realistic density distribution and velocity field from hydrodynamic and plasma simulations. Methods: We performed 3D hydrodynamic simulations of the circumstellar envelope of alpha Sco in combination with plasma simulations accounting for the heating, ionization, and excitation of the wind by the radiation of alpha Sco B. These simulations served as the basis for an examination of circumstellar absorption lines in the spectrum of alpha Sco B as well as of emission lines from the Antares nebula. Results: The present model of the extended envelope of alpha Sco reproduces some of the structures that were observed in the circumstellar absorption lines in the spectrum of alpha Sco B. Our theoretical density and velocity distributions of the outflow deviate considerably from a spherically expanding model, which was used in previous studies. This results in a higher mass-loss rate of (2 +/- 0.5) x 10^-6 M_sun/yr. The hot H II region around the secondary star induces an additional acceleration of the wind at large distances from the primary, which is seen in absorption lines of Ti II and Cr II at -30 km/s.Comment: 12 pages, 14 figures, accepted for publication in A&

Preliminary results in anterior cervical discectomy and fusion with an experimental bioabsorbable cage - clinical and radiological findings in an ovine animal model

Background: Bioabsorbable implants are not widely used in spine surgery. This study investigated the clinical and radiological findings after anterior cervical discectomy and fusion (ACDF) in an ovine animal model with an experimental bioabsorbable cage consisting of magnesium and polymer (poly-ε-caprolactone, PCL) in comparison to a tricortical bone graft as the gold standard procedure. Materials and Methods: 24 full-grown sheep had ACDF of C3/4 and C5/6 with an experimental bioabsorbable implant (magnesium and PCL) in one level and an autologous tricortical bone graft in the second level. The sheep were divided into 4 groups (6 sheep each). After 3, 6, 12, or 24 weeks postoperatively, the cervical spines were harvested and conventional x-rays of each operated segment were conducted. The progress of interbody fusion was classified according to a three-point scoring system. Results: There were no operation related complications except for one intraoperative fracture of the anterior superior iliac spine and two cases of screw loosening and sinking, respectively. In particular, no vascular, neurologic, wound healing or infectious problems were observed. According to the time of follow-up, both interbody fusion devices showed similar behaviour with increasing intervertebral osseointegration and complete arthrodesis in 10 of 12 (83.3%) motion segments after 24 weeks. Conclusions: The bioabsorbable magnesium-PCL cage used in this experimental animal study showed clinically no signs of incompatibility such as infectious or wound healing problems. The radiographic results regarding the osseointegration are comparable between the cage and the bone graft group.Arbeitsgemeinschaft industrieller Forschungsvereinigungen (AiF)German Federal Ministry of Economy and Technology (BMWi

Media and campaign effects on vote choice at national elections in Europe : a review of a multilingual research landscape

This article reviews the empirical research literature on campaign and media effects on vote choice at national elections in European countries for the post-World War II period. Particular efforts are undertaken to obtain a comprehensive picture by including publications in many different languages. With regard to the amount of research, but also the topics addressed, the survey reveals considerable differences between countries. Studies of campaign effects have focused on the temporal dynamics of campaigns, on the modes of campaign communications (such as personal contacts at the local level, advertising on TV and in the press or online social media) and on certain aspects of its content. Research on media effects has explored the role of partisan bias and certain topical categories of news (climate of opinion, issue and candidate coverage) as well as specific new media formats, notably televised candidate debates and vote advice applications (VAA). Overall, the review reveals that there is little in the way of an integrated and consolidated body of campaign and media effects research on national elections in Europe. While political communication research increasingly acknowledges the potential importance of news media and political parties’ electioneering for voting behaviour, there appears as of yet to be little convergence regarding approaches and research findings. Particularly striking is the degree to which research questions are guided by national institutional contexts
