俄罗斯强势复兴及其战略影响

2006年,俄罗斯呈现出强势复兴势头,经济崛起势头强劲,治国理念进一步成熟,外交的自信心与独立性显著增强,军事力量继续提升.强势复兴使普京对俄的国际角色重新定位:在国际政治中,不仅要成为"全球议事日程"的"参与者",更要成为"制定者";在世界经济中,不再做"被剥削者",而要做"得利者";在对原苏联国家关系中,不再做"供养者",而要充当"主导者".俄罗斯复兴及其相应的战略调整对国际格局及中俄关系将产生重大影响.但俄罗斯复兴引起外部强烈反应,俄面临的国际环境未见明显好转.

The Politics of Foreign Direct Investment into Developing Countries: Increasing FDI through International Trade Agreements?

The flow of foreign direct investment into developing countries varies greatly across countries and over time. The political factors that affect these flows are not well understood. Focusing on the relationship between trade and investment, we argue that international trade agreements—GATT/WTO and preferential trade agreements (PTAs)—provide mechanisms for making commitments to foreign investors about the treatment of their assets, thus reassuring investors and increasing investment. These international commitments are more credible than domestic policy choices, because reneging on them is more costly. Statistical analyses for 122 developing countries from 1970 to 2000 support this argument. Developing countries that belong to the WTO and participate in more PTAs experience greater FDI inflows than otherwise, controlling for many factors including domestic policy preferences and taking into account possible endogeneity. Joining international trade agreements allows developing countries to attract more FDI and thus increase economic growth.

蓝舌病病毒单克隆抗体的制备及生物学特性鉴定

以纯化的蓝舌病病毒(BTV)11型VP7免疫BALB/c小鼠,运用淋巴细胞杂交瘤技术,借助间接ELISA筛选,获得了3株分泌抗BTV11 VP7的群特异性单克隆抗体(McAb)的杂交瘤细胞株,命名为C12D9、B4 F3、E1 A7.这3株杂交瘤细胞株连续传代3个月再经液氮冻存6个月后复苏培养,仍能稳定分泌特异性McAb.3株McAb均具有ELISA特性和免疫沉淀特性,其中C12D9株上清液的ELISA效价为1256,腹水的ELISA效价为10-6.亚类鉴定,C12D9株为小鼠IgG1,B4F3、E1 A7为IgG2a和IgG2b.琼脂免疫扩散试验和间接ELISA试验表明,这3株均与BTV11型VP7发生特异性反应,为BTV群特异性McAb.     

Urban Regeneration Policy from the Integrated Urban Development Model in the European Union: an Analytical Approach Based on the Study of Spanish Cities

For several years, local governments have been tackling new challenges related to the regeneration of their cities within the physical sphere, as well as in their economic and social aspects. This task is developed in accordance with what has been called the Integrated Urban Development Model, understanding the integrated nature of this approach not only in terms of the spheres of public policy involved, but also in relation to their management. In this paper, this management is analysed in terms of the development of mechanisms for New Local Governance and New Public Management (NPM). Using Spanish municipalities as a case study, this paper develops an analytical tool for the analysis of this model of urban intervention within the European context, paying close attention to the development of mechanisms for New Local Governance from a multilevel perspective, as well as the development of mechanisms for NPM.
