Russia’s role in ‘animation’ of the Kyoto Protocol was crucial. Its initial vacillation on ratification was predominantly
due to political bargaining with the EU. Domestic economic rationales [i.e. impacts of emission trading and Joint Implementation
(JI) projects] were important to a much lesser extent and environmental motives did not seem to play any role in the decision.
Since the Protocol entered into force, there have been significant delays in complete establishment of policy implementation
frameworks, which are necessary for Russia to start benefiting from JI and emission trading. Only recently, in 2007, have
GHG inventories and a national registry been established and the responsibilities for implementation of the Protocol and JI
among the government departments have been distributed only to a certain extent. Some constraints hindering JI projects, such
as vague legislation, an unfavourable economic climate, lack of commitment to JI projects, corruption, xenophobia, state and
agency ‘capture’ still remain.

This article contributes to the ongoing debate on the economic determinants of fertility behavior by addressing the role of
job insecurity in couples’ intentions concerning parenthood and its timing. It starts from the hypothesis that cultural values
moderate individuals’ reactions to job insecurity and the way it is related to family formation. With a systematic thematic
content analysis of a set of semi-structured interviews with childless men and women around the age of 30 in eastern and western
Germany, we are able to show that there are substantial differences in the consequences of job insecurity on intentions to
have a first child. In western Germany, a relatively secure job career is expected to precede family formation, and this sequence
of transitions is rather rigid, whereas in eastern Germany job security and family formation are thought of and practiced
as parallel investments. We suggest that the lack of convergence in family formation patterns between eastern and western
Germany after the unification of the country in 1990 is partially related to different attitudes toward job insecurity in
the two contexts. 相似文献

American options in discrete time can be priced by solving optimal stopping problems. This can be done by computing so-called
continuation values, which we represent as regression functions defined recursively by using the continuation values of the
next time step. We use Monte Carlo to generate data, and then we apply smoothing spline regression estimates to estimate the
continuation values from these data. All parameters of the estimate are chosen data dependent. We present results concerning
consistency and the estimates’ rate of convergence. 相似文献

This paper proposes an experimental test to evaluate the performance of the serial cost sharing rule, originally proposed
by Shenker [Sigmetrics, 241–242 (1990)] and then analyzed by Moulin and Shenker [Econometrica 60, 1009–1037 (1992)]. We report
measures of the performance and efficiency of the serial mechanism by comparing the choices and payoffs attained by the subjects
to the expected equilibrium allocations. Experimental evidence shows that learning is needed for the subjects to converge
to the equilibrium strategy. However, in terms of efficiency, the serial mechanism leads to almost efficient allocations. 相似文献

机会是企业战略的实体,企业战略生命周期的本质体现为"机会创造性毁灭"的过程;企业家精神通过机会识别、机会资本化、资源获取与控制、结构优化作用于"机会创造性毁灭"的过程,从而形成企业战略演化;战略的平滑化演化创造出企业的持久竞争优势;当前中国企业家精神从"制造至上"过于偏向"市值至上"的断裂与浮躁,已经对以实业为基础的中国企业战略演化造成了紊乱. 相似文献

Gay affirmative practice has recently been introduced into the social work literature as a culturally sensitive model for
working with gay, lesbian, and bisexual (GLB) adults, however, this model has rarely been applied to practice with GLB youth.
In this article, the authors review the literature to present the main tenets of gay affirmative practice, outline the challenges
that GLB youth face, and delineate the environmental and individual strengths that can be enhanced to promote well-being.
The authors then apply the gay affirmative practice model to GLB youth, offering concrete information about the specific knowledge,
attitudes, and skills that social workers should acquire to better serve the unique, yet diverse, needs of GLB youth. 相似文献
