Testing the limits of freedom of contract: the commercialization of reproductive materials and services

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.     

Physiologic Responses to Racial Rejection Images Among Young Adults from African-American Backgrounds

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.

Repression and Monarchical Resilience in the Arab Gulf States

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.     

20世纪国际关系领域的基准时间:历史视角中的三次世界大战

基准时间是宏观历史过程中的临界点,标志着一连串的重大变革可能会在较长时间内延续。基准时间具有九条标准,可以分为一等基准时间、二等基准时间和三等基准时间。20世纪的基准时间主要包括三次世界大战(一战、二战和冷战),第二次世界大战前后发生的变革比第一次世界大战和冷战前后的变革都要来得更为深远。将20世纪的三个基准时间置于两个世纪的视角中加以审视,可以突出现代性革命,这种视角能够观察20世纪的三个基准时间在正在展开的"全球性变革"这一大的主题下是否会相互联接、是如何相互联接的。20世纪国际政治的关键事件,都应该被视为19世纪"全球性变革"所引发的发展态势和挑战的后期结果。
