This study examines the role of the UN’s programmes for environment and development (UNEP and UNDP) in the genesis and implementation of multilateral environmental agreements (MEAs). This is set in the wider context of the changing dominant focus of the international agenda, from ‘environment’ at the Stockholm Conference in 1972, to ‘environment and development’ at Rio in 1992, and ‚sustainable development’ in Johannesburg in 2002. UNDP is a development organisation strongly rooted in its country office network. Its role is becoming increasingly normative however, particularly since 2002 when UNDP opted to root most of its activities on the Millennium Development Goals. UNEP, as an environmental organisation has been successful at catalysing MEAs at the global and regional level; but without a significant increase in its budget over 30 years, its capacity has been spread very thinly. Many of the institutional arrangements for MEAs have effectively become independent of UNEP resulting in a very loosely and sometimes poorly coordinated network. Two case studies are used to illustrate the current institutional arrangements: UNEP’s Regional Seas Conventions and Protocols, and the Convention for Biological Diversity. These illustrate the fragmentation of current institutions, the need for strengthened technical and scientific support, the importance of addressing problems at their root causes and the need to increase the devolution of global governance to the regional level. Satisfying the identified needs requires actions within the remit of both UNEP and UNDP. It is argued that current institutional arrangements have not kept pace with the requirements of evolving policy. As part of a reform process, one option may be to merge the two programmes into a single structure that conserves and strengthens vital technical functions but enables a balanced and integrated approach to sustainable development.  相似文献

The extent of strategic voting in the Spanish general elections of 2000, 2004 and 2008 is estimated using a new measure of strategic incentives suitable for proportional representation systems that avoids some of the problems associated with lagged variables. Strategic behaviour increased from 12 to 33 per cent of the electoral base of the United Left Party, the major victim of strategic defection. This estimate is a conservative one as elite mobilisation is controlled for in the constituencies, which is unusual in the literature on strategic voting that uses regression‐based methods.  相似文献

How quickly, to what extent and under what conditions do voters and elites adapt to new electoral institutions in order to not waste their votes and effort on hopeless competitors? A latent‐curve model of strategic adaptation is developed and fitted to district‐level election data from Spain. The extent of strategic adaptation is generally found to vary with the strength of the electoral system. However, grave ethnic tensions are demonstrated to seriously retard adaptation even under favourable institutional conditions.  相似文献

正Chinese Premier Li Keqiang’s four-day trip to Britain in June is expected to energize the China-Britain comprehensive strategic partnership,which sees its 10th anniversary this year,and whose strategic,reciprocal and global signif icance continues to grow.The trip,Li’s f irst to Britain since taking off ice in March last year,marks another major diplomatic event between China and Europe following President Xi Jinping’s Europe tour in late March.During his visit the Chinese premier met with Queen Elizabeth II  相似文献

Historical experience of resolving territorial disputes in all parts of the world shows that the disputed territory itself has neither the strategic depth nor sufficient maneuvering space. It is hard to make any progress when solely focusing on resolving the territorial issue. How to keep the territorial issue in a controllable and appropriate place has posed a great challenge to the Northeast Asian countries.  相似文献

An STR null allele is an allele at a microsatellite locus that fails to amplify. A possible cause is poor primer annealing due to nucleotide sequence divergence in the flanking primers. In this study, a woman (ZAM) wanted to know whether a man (PGAF) was the father of her child (ZGC). During the court settlement, PGAF died. PGAF’s parents refused to undergo DNA investigation and denied the access to biological fragments from their dead son. Although, DNA specimens were obtained from buccal swabs of ZAM, ZGC and PGAF’s paternal sister (PTFS). Initially, only autosomal profiles were studied, and kinship assignment was inconclusive. Following our requests, PGAF’s parents (PRGF and LLGM) led us to obtain their DNA specimens. Only with the PTFS genetic profile, we were not able to demonstrate a kinship assignment. PTFS showed a homozygosis at D8S1179 locus. Then, merely comparing PTFS, LLGM and ZGC autosomal genetic profiles it was possible to underline that they were three different homozygous at D8S1179 locus. Hence, comparing the peak heights in different loci and according to literature, they had to carry a null allele at this locus. Parental studies were completed by Y haplotype analysis.  相似文献
