The first international proficiency test on ketamine and norketamine in hair

This paper discusses the organization of the first international proficiency test (PT) programme on ketamine (K) and norketamine (NK) in hair samples. The primary objective of the programme was to evaluate the analytical capability of participating laboratories on hair analysis for K and NK via comparison of results. Authentic samples, instead of spiked samples were used in the programme to mimic the analysis of incorporated illicit drugs in real-life situations. Eight of the ten participating medical or forensic laboratories from Australia, France, Hong Kong, Italy, Singapore and the USA returned results to the organizer. Quantification methods from these laboratories were confined to GC-MS and LC-MS/MS. Performance assessment based on z-score indicated that only three laboratories achieved satisfactory results for both the analysis of K and NK. It was concluded that the overall performance of the participating laboratories was fair and there is still room for further improvement. Additional similarly designed PT programmes are recommended to be organized in order to encourage reliable measurements of illicit drugs in hair samples. Taking into account the substantial effect on the consensus values within limited number of data points, a recommendation on the provision of reference values assigned by accurate methods will be of benefit to small size PT programmes in the forensic field.     

Umbilical cord blood banking: beyond the public-private divide

Umbilical cord blood is a source of haematopoietic progenitor cells, which are used to treat a range of malignant, genetic, metabolic and immune disorders. Until recently, cord blood was either collected through donations to publicly funded cord blood banks for use in allogeneic transplantation, or stored in commercial cord blood banks for use in autologous transplantation. The line between public and private cord blood banking is being blurred by the emergence of "hybrid" models that combine aspects of both the public and private systems. The authors describe these hybrid models and argue that their emergence is explained by both market forces and public sector policy They propose that the future of the sector will depend heavily on several key developments that will differentially affect public, private and hybrid banking models.     

Racially conditional donation: the example of umbilical cord blood

While direction of donated tissue to family members has long been accepted, direction to members of specific racial groups has been opposed, on the basis that it is discriminatory and contrary to the ethos the institution of organ donation seeks to promote. It has, however, recently been proposed that racially conditional donation may provide a useful--and ethically acceptable--way to address the social inequalities and injustices experienced by certain cultural groups. This article examines the ethical, legal and cultural arguments for and against racially conditional donation, concluding that the practice is more likely to undermine the values of equity and justice than to promote them and that it may also lead to other unfavourable personal and social outcomes.     

The Resurgence of Chinese Anti-Americanism in the 1990s： State Policy or Popular Expression？

While Western observers typically attribute the population＇s nationalist anti-Americanism largely to government propaganda or manipulation, they misunderstand the roots of anti-American behavior in China. As depicted by Peter Hay Gries in China＇s New Nationalism and by Michael H. Hunt in The Genesis of China＇s Foreign Policy, a more nuanced portrayal is in order. While the two books utilize distinct socialpsychological and historical perspectives, an integrative reading of the two suggests that popular expression is in fact largely responsible for China＇s anti-Americanism. At first this conclusion in favor of popular expression may seem at odds with Hunt＇s state-centered analysis of the roots of foreign policy. Nevertheless, after a brief summary of each book and a comparative application to the issue of anti-Americanism, the authors demonstrate that applying a comparative historical reappraisal to Hunt＇s study suggests that both scholarly works support the predominant role of popular expression on contemporary China＇s nationalist anti- Americanism.     

Kevin Kelly's Complexity Theory: The Politics and Ideology of Self-organising Systems

Regarded as a contemporary prophet of the new technology and economy, widely acclaimed author and editor of Wired , Kevin Kelly argues that the realms of nature and human construction are becoming one. Human-made things are becoming more lifelike and life is becoming more engineered. Utilising complexity theory and other concepts fashioned on the paradigmatic logic of biological systems, Kelly envisions a future with radically different forms of social and organisational control. In this future world, control is dispersed in highly pluralistic, open, and decentralised systems. Natural, technological, economic and social elements of the system co-evolve towards a superior, neo-biological civilisation that (among other things) will foster bottom-up control, co-ordinated change and co-operation among all elements. We contest Kelly's metaphysic of the new economy and new technology, arguing that he illicitly collapses technology and the economy into nature, using nature metaphors to legitimate the new forms of economy and organisation. We argue that Kelly fails to factor in the logic of capital into his scenario and does not explore the consequences of the new organisation of economy and new technology for the environment and society.
