Abstract

While analysis of the effectiveness of the Convention on International Trade in Endangered Species (CITES) often focuses on its ability to ensure sustainable trade in the species it regulates, the treaty also contains many provisions intended to ensure the welfare of species introduced into international trade. While such provisions serve salutary objectives, they are often complied with only in the breach. Efforts should be made by the Parties to CITES to ensure implementation of the animal welfare provisions of CITES through stricter enforcement measures, enactment of national legislation and an interpretation of treaty provisions that furthers the underlying welfare objectives of the Convention.  相似文献

The Bahamian archipelago has been influenced by a wide array of settlers (Lucayans, Eleutherian Adventurers, British Loyalists, Creoles from the United States and African slaves) throughout its short but dynamic history. Nevertheless, the Bahamas remains poorly characterized genetically and little is known about each group's contribution to the island chain. In the current study, the population of New Providence was analyzed based on 15 autosomal STR loci routinely employed in forensic DNA fingerprinting applications. A comparison of this collection with African groups reveals similar genetic profiles to West African populations from Equatorial Guinea and Angola, possibly resulting from the importation of slaves from West African ports during the Transatlantic Slave Trade. Although the New Providence collection exhibits strong genetic affinities to the two US African American reference populations, the detection of unique alleles among them may necessitate the utilization of population-specific databases in forensic cases especially when the STR profiles include these specific variants.  相似文献

Food security is political. The identification of food insecurity and the development and implementation of responses to it are enveloped in layers of politics and power. This politics might not be as readily apparent in emergency situations where broad agreement on the need for a response is evident. But in the everyday governance of food it must not be forgotten that food security is a contested concept. This article offers a preliminary elucidation of this politics in the Central African context. To do so it presents findings from an analysis of publicly available information and media reports. This analysis hones in on the perspectives of differently situated stakeholders on food security imperatives in the Central African Economic and Monetary Community. To identify similarities and differences in the levels of emphasis different stakeholders place on different aspects of food security, the authors employ Olivier De Schutter's understanding of the relevant dimensions. Specific terms used in the presentation of food security information are associated with one of the three dimensions of food security advanced by De Schutter: availability, accessibility and adequacy. In light of this analytic approach, the article finds that stakeholders – including businesses, civil society groups, governments and multilateral and bilateral partners – do not necessarily articulate similar viewpoints on food security. There is simply no unified view on what should be done to advance food security in Cameroon, Central African Republic, Chad, Congo-Brazzaville, Equatorial Guinea or Gabon. That being said, the article does identify intriguing areas of convergence.  相似文献

The rapid progression of the Internet has impacted dramatically on contemporary society, transforming communications, business and trade. The global nature of the Internet has challenged traditional models of regulation. What has emerged is a new international framework, governed by an increasing number of actors and regulatory processes. By drawing upon the regulatory experience of the Internet, including an examination of the forces and dynamics that have shaped the regulatory framework, this paper considers the regulatory developments of another emerging and ubiquitous technology, nanotechnologies. It examines the rapid advancement and promise of nanotechnology-based products and processes, and the policy and regulatory challenges facing government, regulators, and industry alike. The paper argues that while the regulatory future for nanotechnologies appears to be uncertain, and highly contested, regulatory regimes will most likely reflect the commodities and services that the technology helps to produce. Anything other than this is unlikely because the ‘nanotechnology genie’ is already out of the bottle, and regulatory issues will evolve as the nature of the technology itself evolves.  相似文献

This article assesses current work in criminal justice theory and identifies two criteria for theory—that which appeals to empirical validation, and that which appeals to historical tradition. Appeals to empirical validation are consistent with a scientific model, while appeals to historical tradition are consistent with an interpretive model of social science. Both models are described and the way in which each contributes to theory in criminal justice is discussed.  相似文献

This article discusses the phenomena of nanotechnology, and notes that despite high investment levels for global research and development, the public presently understands neither the implications of this emerging technology nor how it might be best governed. It considers the notion of the public interest and its place in the public policy cycle, and notes some of the specific challenges posed by this new technology. Adopting a comparative jurisdictional approach, this article maps a range of policy and dialogue activities currently underway within the United Kingdom and Australia and concludes that policy dialogue is an essential component of public policy development for all emerging technologies. While the Australian government is currently beginning this process, compared to countries such as the United Kingdom, such efforts here are still embryonic. A fuller engagement in wide‐ranging public debate is suggested as a part of protecting the public interest.  相似文献

Legal Treatment of Cohabitation in the United States*   总被引:2,自引:0,他引:2  
This article discusses the variety of ways state legal systems in the United States treat cohabitation, both by same-sex and heterosexual couples. The different approaches are described along a spectrum that ranges from one extreme, under which cohabitants have essentially no rights against one another or against third parties, to the other extreme, under which cohabitants are to be treated as though they were married under state law. Different areas of law are discussed, including the rights of cohabitants both against one another (remedies upon dissolution, inheritance) and against third parties, such as state benefits, tort claims, health-related benefits, and rights concerning children. The article concludes with speculations concerning why the remedies offered to cohabitants in the United States are so limited, as compared with other countries.  相似文献
