From 1 April 2005, UK law was changed to allow children born through gamete donation to access identifying details of the donor. The decision to abolish donor anonymity was strongly influenced by a discourse that asserted the 'child's right-to-know' their genetic origins. Under the current regulation, if would-be parents want to receive treatment in the UK, they have no option but to use gametes/embryos from identifiable donors. For a majority, this also means that they will be on lengthy waiting lists due to the donor shortage. Interestingly, the voice of would-be parents -those who would be most affected by a contraction in donor supply and would carry the burden of informing children of their origins, should they so choose-were not heard during the donor anonymity debate or thereafter.Adopting a social constructionist approach, this thesis studies removal of donor anonymity as a social problem and examines why would-be parents remained silent during the public debate.There are two major steps taken: first, examining the donor anonymity debate in the public realm through media presentations, and secondly investigating would-be parents' reactions through ethnographic studies: a virtual ethnography study and interviews.

This article responds to that appeal by focusing specifically on prison governance in the UK. It aims, first, to draw attention to a range of intersections between risk and human rights, and argues that these intersections require analysis. Secondly, it suggests some key features of a 'risk and rights' analysis by drawing upon insights from within criminology, human rights law and regulation scholarship. In order to explore these issues, we have divided the article into three parts. The first part speculates on British criminology's (non) engagement with human rights and queries why the growth in prisoner rights litigation has not registered in criminology scholarship on prisons. 2 Then, in the second part, we highlight the widespread lack of engagement with risk amongst (human rights) lawyers, both at the theoretical level and in terms of the uses of risk assessment and management in legal practice. In the final part of the article, we argue that criminologists and lawyers should be examining the co-existence of risk and rights discourses in UK prison governance and we suggest some key features of a 'risk and rights' stream of academic enquiry. Part One: Criminologists and Human Rights

The orthodontic workforce is becoming increasingly feminised. The cumulative effect of more women completing fewer cases will mean that workforce planners will need to consider increasing numbers to allow for this feminisation.

In this paper, we give an overview of the Cedar mutliprocessor and present recent performance results. These include the performance of some computational kernels and the Perfect Benchmarks@ . We also present a methodology f o r judging parallel system performance and apply this methodology to Cedar, Cray YMP-8, and Thinking Machines CM-5.

1. Exogenous enzymes such as xylanase are used in diets for broilers to eliminate anti-nutritive effects caused by the presence of non-starch polysaccharides (NSP). It has been proposed that the mechanism by which xylanases exert their effect is through reducing in vivo viscosity within the broiler digestive tract. Previous research has reported that in vitro viscosity was a reasonable predictor of in vivo viscosity and that this method could be used to assess the efficacy of xylanases. 2. The objective of this study was to examine the response of broilers offered a wheat-based diet supplemented with a range of xylanases, varying in ability to reduce in vitro viscosity. 3. A total of 18 xylanases (Syngenta Animal Nutrition) were used to investigate the effect of xylanase on wheat in vitro viscosity. For the in vitro viscosity assay, pepsin was dissolved in either 005 or 01 M hydrochloric acid (HCl). 4. A wheat-based diet was formulated, produced and split into 7 batches; xylanase (500 U/kg) was sprayed onto 6 of the batches and the 7th was the control. This was repeated three times to produce a total of 21 diets, 18 of which contained xylanase. 5. The experiment was conducted in three consecutive trials. Each trial utilised 63 male, Ross broilers from 7 to 28 d of age. Dry matter intake (DMI), liveweight gain (LWG) and gain:feed were determined weekly. Excreta were collected from d 14 to 21 for determination of apparent metabolisable energy (AME). Oil and neutral detergent fibre (NDF) digestibility and ileal digestibility of dry matter (DM) and starch were determined. 6. Regression analyses were applied to the mean intestinal viscosity against DMI, LWG, gain:feed and the ratio of metabolisable energy to gross energy (ME:GE). To compare xylanases across the three trials, the data were subjected to REML analysis (Genstat 5). 7. When 01 M HCl was used for dissolution of pepsin, considerable reductions in in vitro viscosity were achieved for the majority of the xylanases-to values less than 12% of the control treatment. When 005 M HCl was used for the dissolution of pepsin, initial viscosity values were lower and the reduction in in vitro viscosity less dramatic than that observed with 01 M HCl. 8. With the exception of diets containing xylanases 9003 and 7162, significant reductions in in vivo viscosity were observed for diets containing xylanase in comparison to the control diet. 9. In terms of gain:feed, ME:GE and AME the xylanases ranked best were 2230 and 9003. Xylanase 2230 also resulted in the highest values for ileal DM and starch digestibility. 10. There were weak but significant relationships between in vitro viscosity and in vivo jenjunal digesta viscosity when in vitro viscosity was determined using either 01 or 005 M HCl (r(2)= 0287 and 0240, respectively). 11. The relationship between jejunal viscosity and DMI was significant (P < 005) but relatively poor (r(2)= 023). There were also significant (P < 005) relationships between jejunal digestal viscosity and gain:feed and ME:GE (r(2)= 034 and 028, respec...

Consider, for example, the proliferation of references to 'preparedness'; specifically, 'public health emergency preparedness' and its more specialised variants such as 'public health emergency legal preparedness' and 'international legal preparedness'. There is also increasing use of related phrases such as 'global public health security' and 'international health security'. Of course, a proliferation of terms is not enough to prove that a new force is in play: language shifts all the time in all sorts of areas, and although such changes may reflect and contribute to deep social transformation, they can also be nothing more than passing fashions with little or no impact. But public health emergency preparedness does not feel like a superficial, short-lived trend: in fact, it seems almost the exact opposite. Indeed, as David Fidler and Laurence Gostin emphasise in their recent book, Biosecurity in the Global Age, a 'policy revolution' seems to have taken place -a revolution brought about by a 'collision' of public health and security. 1 The collision of security and public health is our focus in this article. But before explaining why, we need to define 'public health emergency preparedness', in particular its impressive-sounding correlate, 'global public health security', and its less readily comprehensible subset, 'public health emergency legal preparedness'. In the World Health Report 2007, Dr Margaret Chan, Director-General of the World Health Organization (WHO), described 'global public health security' as 'the reduced vulnerability of populations to acute threats to health'. 2 Later in the same report, more detailed definitions were provided:
