This article examines the cases for and against commercializing, or "commodifying," reproductive materials and services. Using a supply/demand third-party framework, three basic scenarios in which commercial-exchange relationships may be possible--exchange of gametes and zygotes, exchange of gestational services, and exchange of fetal material--and the major parties of interest, or stakeholders, are identified. The study sketches the liberal, essentialist, and radical contingency theories that shape the debate over the commercialization of reproductive materials and services. The article then attempts to derive some basic governing principles that reflect as much common ground as possible amongst these various normative perspectives, while recognizing that complete reconciliation is impossible. Taken together, these principles are designed to reflect a strategy of "constrained commodification," where commercialization or commodification, that is, financial remuneration, plays a relatively neutral role in the utilization of reproductive materials and services. In light of these principles, the article concludes by sketching legal and regulatory regimes with respect to the exchange of gametes and zygotes, gestational services, and fetal tissue.  相似文献

While its economic dynamism stimulates continued growth in Asia, China's increasing demand for energy is creating intense competition, particularly with Japan, over international sources of supply. Domestic fields have generally been disappointing, as have efforts to pipe gas from Central Asia and Russia to the east coast. Consequently, China is not only paying greater attention to potential petroleum resources in the East and South China Seas, but also considering the vulnerability of its sea-lanes to the Middle East and beyond. Its need to diversify has promoted closer relations with Central Asia, the Middle East, and the oil producing countries of Africa and Latin America, but the jury is out on whether China's concerns for secure energy supply will lead to international cooperation against terrorism or fuel the already heated competition for oil and gas. As China continues to assure its future energy security in Asia and many areas of the world, sustained bilateral and multilateral diplomacy to reconcile disputes and avoid conflict will become more important than ever.  相似文献

Brexit and the coronavirus pandemic have put relationships between the UK government and its devolved counterparts under growing strain. Tensions generated by both of these developments have exposed the inadequacies of the existing, under-developed system for bringing governments together in the UK. The limitations of the current system include the ad hoc nature of intergovernmental meetings, and their consultative rather than decision-making character. Drawing upon an analysis of how intergovernmental relationships are structured in five other countries, the authors offer a number of suggestions for the reconfiguration of the UK model. They explore different ways of enabling joint decision making by its governments, and argue against the assumption that England can be represented adequately by the UK administration. Without a serious attempt to address this dysfunctional part of the UK’s territorial constitution, there is every prospect that relations between these different governments will continue to deteriorate.  相似文献

Physiologic reactivity to racially rejecting images was assessed in 35 young adults (10 males, 25 female) from African-American backgrounds using the startle probe paradigm. In a laboratory setting, participants viewed 16 images depicting racial rejection, racial acceptance, nonracial negative, and nonracial positive themes. While viewing these images, startling bursts of noise were presented and the magnitude of the eyeblink responses were measured. Results supported an attentional mechanism which suggests that, while viewing both racially rejecting and nonracial positive images, individuals may be so absorbed in processing the images that they appear less distracted by the startling noise. However, these patterns were only found for participants low in racial regard. Young adults who felt positively about their racial background did not exhibit differential processing of startle stimuli as a function of slide themes. Race-rejection sensitivity did not moderate startle reactivity. Developmental implications, particularly in light of coping with racial discrimination, are discussed.

Historian, activist and campaigner Edward Thompson is seen as an exemplar of an English radicalism which some see as a lineage with which the contemporary Labour party might fruitfully reconnect. This article examines how Thompson himself understood and characterised the ‘English radical idiom’ and traces his use and then abandonment of this idea in the middle years of his career. It offers some wider reflections about what the insights and lessons associated with his historical writings and reflections on the distinctive nature of English cultural and social thought.  相似文献

Why the uprisings that broke out across the Middle East and North Africa in 2010-11 ousted the leaders of republics but left monarchies largely intact remains puzzling. One promising explanation for the resilience of monarchical regimes argues that monarchs exercise repression in a comparatively restrained and largely effective fashion. Proponents of this theory tend to conflate two crucial causal factors: the level of state coercion exercised against opposition activists and the degree of indiscriminateness with which coercion is deployed. By treating these variables as analytically distinct, a more compelling explanation for monarchical resilience can be advanced. The advantages of the revised argument are illustrated by revisiting the divergent trajectories of the uprisings in Bahrain, Oman, Saudi Arabia and Kuwait.  相似文献
