Who do we treat when resources are scarce?

In a health service with limited resources we must make decisions about who to treat ?rst. In this paper I develop a version of the restoration argument according to which those whose need for resources is a consequence of their voluntary choices should receive lower priority when it comes to health care. I then consider three possible problems for this argument based on those that have been raised against other theories of this type: that we don’t know in a particular case that the illness is self-in?icted, that it seems that all illness is self-in?icted in the sense used in my argument, and ?nally that this type of approach incorporates an unacceptable moralising element if it is to avoid giving those like ?re-?ghters a lower priority for treatment. I argue that the position outlined here has the resources to respond to each of these objections.

We Never Give Up II

Ten years after the production of the initial 'We Never Give Up' film, this documentary filmis a follow-up film about the experiences of ten survivors of South Africa apartheid and their struggle for reparations. Produced by the Human Rights Media Centre, Cape Town, the film was directed and filmed by Cahal McLaughlin in a collaborative relationship with Khulumani Support Group Western Cape.

Further Information:

This documentary film, produced with the Human Rights Media Centre, Cape Town, and in collaboration with Khulumani Support Group Western Cape, is the ten-year follow up to We Never Give Up (2002), which addressed the issues of reparations as dealt with by the South African government and the Truth and Reconciliation Commission. We Never Give Up II (2012) returns to these themes and to the same participants, asking how life has changed in the interim. The process of collaborative practices acknowledges the importance of sharing ownership/authorship in the storytelling processes as well as in validating traumatic experiences by those who survived major and sustained political violence. Made over a two-year period, involving close consultation with participants, the film offers insights, by those most directly affected, to what might constitute legal, financial, social and psychological reparations. The film has been screened in Cape Town, Bloemfontain, Zanzibar Film Festival, Belfast (Belfast Film Festival), Brighton, Guildford, Galway and London, always accompanied by discussion of the issues raised in Q&As. To emphasise the importance of the film for debates on policy around reparations, a 25 minute edited version was selected to be screened on SABC on ‘Special Assignment’ by SABC on April 29th, 2013 (South Africa’s ‘Freedom Day’), followed by a debate with Department of Justice spokesperson, Dr Khotso De Wee. The chapter 'Maureen Never Gave Up' in Daniels, McLaughlin and Pearce (eds.) 'Truth, Dare or Promise' (2013) Cambridge Scholars Press (ISBN: 1-4438-4959-6, ISBN 13: 978-1-4438-4959-3, Release Date: 2013-09-01), which analyses the production of this film, is offered as part of the portfolio.

Valuing the talk of young people: are we nearly there yet?

This paper examines reasons why young people’s talk about themselves and their educational experiences do not seem to be valued in public discourse about education. Drawing on a national dataset of student focus groups, it illustrates how students talk about themselves in educational contexts in a way that is entirely different and more complex than how they are conceptualised by an adult audience and symbolic elites. It demonstrates, contrary to dominant adult perceptions, the critical, communicative and creative use of language offered by young people when asked about their educational experiences, and highlights the potential innovation being missed by not listening.

Can we trust mass spectrometry for determination of arsenic peptides in plants:comparison of LC-ICP-MS and LC-ES-MS/ICP-MS with XANES/EXAFS in analysis of Thunbergia alata

The weakest step in the analytical procedure for speciation analysis is extraction from a biological material into an aqueous solution which undergoes HPLC separation and then simultaneous online detection by elemental and molecular mass spectrometry (ICP-MS/ES-MS). This paper describes a study to determine the speciation of arsenic and, in particular, the arsenite phytochelatin complexes in the root from an ornamental garden plant Thunbergia alata exposed to 1 mg As L(-1) as arsenate. The approach of formic acid extraction followed by HPLC-ES-MS/ICP-MS identified different As(III)-PC complexes in the extract of this plant and made their quantification via sulfur (m/z 32) and arsenic (m/z 75) possible. Although sulfur sensitivity could be significantly increased when xenon was used as collision gas in ICP-qMS, or when HR-ICP-MS was used in medium resolution, the As:S ratio gave misleading results in the identification of As(III)-PC complexes due to the relatively low resolution of the chromatography system in relation to the variety of As-peptides in plants. Hence only the parallel use of ES-MS/ICP-MS was able to prove the occurrence of such arsenite phytochelatin complexes. Between 55 and 64% of the arsenic was bound to the sulfur of peptides mainly as As(III)(PC(2))(2), As(III)(PC(3)) and As(III)(PC(4)). XANES (X-ray absorption near-edge spectroscopy) measurement, using the freshly exposed plant root directly, confirmed that most of the arsenic is trivalent and binds to S of peptides (53% As-S) while 38% occurred as arsenite and only 9% unchanged as arsenate. EXAFS data confirmed that As-S and As-O bonds occur in the plants. This study confirms, for the first time, that As-peptides can be extracted by formic acid and chromatographically separated on a reversed-phase column without significant decomposition or de-novo synthesis during the extraction step.

Postglacial dispersal, rather than in situ glacial survival, best explains the disjunct distribution of the Lusitanian plant species Daboecia cantabrica (Ericaceae)

Aim:

The distribution of the Lusitanian flora and fauna, species which are found only in southern and western Ireland and in northern Spain and Portugal but which are absent from intervening countries, represents one of the classic conundrums of biogeography. The aim of the present study was to determine whether the distribution of the Lusitanian plant species Daboecia cantabrica was due to persistence in separate Irish and Iberian refugia, or has resulted from post-glacial recolonization followed by subsequent extinction of intervening populations.

Location:

Northern Spain and Co. Galway, western Ireland.

Methods:

Palaeodistribution modelling using Maxent was employed to identify putative refugial areas for D. cantabrica at the Last Glacial Maximum (LGM). Phylogeographical analysis of samples from 64 locations in Ireland and Spain were carried out using a chloroplast marker (atpB–rbcL), the nuclear ITS region, and an anonymous nuclear single-copy locus.

Results:

The palaeodistribution model indicated areas with a high probability of survival for D. cantabrica at the LGM off the western coast of Galicia in Spain, and in the Bay of Biscay. Spanish populations exhibited substantially higher genetic diversity than Irish populations at all three loci, as well as geographical structuring of haplotypes within Spain consistent with divergence in separate refugia. Spanish populations also exhibited far more endemic haplotypes. Divergence time between Irish and Spanish populations associated with the putative Biscay refugium was estimated as 3.333–32 ka.

Main conclusions:

Our data indicate persistence by D. cantabrica throughout the LGM in two separate southern refugia: one in western Galicia and one in the area off the coast of western France which now lies in the Bay of Biscay. Spain was recolonized from both refugia, whilst Ireland was most likely recolonized from the Biscay refugium. On the balance of evidence across the three marker types and the palaeodistribution modelling, our findings do not support the idea of in situ survival of D. cantabrica in Ireland, contrary to earlier suggestions. The fact that we cannot conclusively rule out the existence of a small, more northerly refugium, however, highlights the need for further analysis of Lusitanian plant species.

Can we meet targets for biofuels and renewable energy in transport given the constraints imposed by policy in agriculture and energy?

The deployment of biofuels is significantly affected by policy in energy and agriculture. In the energy arena, concerns regarding the sustainability of biofuel systems and their impact on food prices led to a set of sustainability criteria in EU Directive 2009/28/EC on Renewable Energy. In addition, the 10% biofuels target by 2020 was replaced with a 10% renewable energy in transport target. This allows the share of renewable electricity used by electric vehicles to contribute to the mix in achieving the 2020 target. Furthermore, only biofuel systems that effect a 60% reduction in greenhouse gas emissions by 2020 compared with the fuel they replace are allowed to contribute to meeting the target. In the agricultural arena, cross-compliance (which is part of EU Common Agricultural Policy) dictates the allowable ratio of grassland to total agricultural land, and has a significant impact on which biofuels may be supported. This paper outlines the impact of these policy areas and their implications for the production and use of biofuels in terms of the 2020 target for 10% renewable transport energy, focusing on Ireland. The policies effectively impose constraints on many conventional energy crop biofuels and reinforce the merits of using biomethane, a gaseous biofuel. The analysis shows that Ireland can potentially satisfy 15% of renewable energy in transport by 2020 (allowing for double credit for biofuels from residues and ligno-cellulosic materials, as per Directive 2009/28/EC) through the use of indigenous biofuels: grass biomethane, waste and residue derived biofuels, electric vehicles and rapeseed biodiesel. © 2010 Elsevier Ltd.

How much gas can we get from grass?

Grass biomethane has been shown to be a sustainable gaseous transport biofuel, with a good energy balance, and significant potential for economic viability. Of issue for the designer is the variation in characteristics of the grass depending on location of source, time of cut and species. Further confusion arises from the biomethane potential tests (BMP) which have a tendency to give varying results. This paper has dual ambitions. One of these is to highlight the various results for biomethane potential that may be obtained from the same grass silage. The results indicated that methane potential from the same grass silage varied from 350 to 493 L CH4 kg−1 VS added for three different BMP procedures. The second ambition is to attempt to compare two distinct digestion systems again using the same grass: a two stage continuously stirred tank reactor (CSTR); and a sequentially fed leach bed reactor connected to an upflow anaerobic sludge blanket (SLBR–UASB). The two engineered systems were designed, fabricated, commissioned and operated at small pilot scale until stable optimal operating conditions were reached. The CSTR system achieved 451 L CH4 kg−1 VS added over a 50 day retention period. The SLBR–UASB achieved 341 L CH4 kg−1 VS added at a 30 day retention time.

Diagnosing diabetes mellitus - Do we need new criteria?

The current classification and diagnostic criteria for diabetes mellitus were introduced by the United States National Data Group in 1979 and endorsed by the World Health Organization in 1980, with modifications in 1985 and 1994. The criteria, chosen to reflect the risk of complications, were the synthesis of considerable thought and expertise and represented a consensus which, it was hoped, would prove helpful to all those involved with diabetes practising clinician, research scientist and epidemiologist alike. The inconvenience, variability and nonphysiological nature of the oral glucose tolerance test (OGTT) are well-recognised. In spite of these limitations the 2-h post-load plasma glucose has remained the standard against which all other tests have been evaluated. This article reviews the original justification for the OGTT, and in the light of more recent epidemiological research seeks to place the current diagnostic criteria for diabetes into a pathophysiological, diagnostic and prognostic perspective.

“Shall we playe the good girles”: Playing Girls, Performing Girlhood on Early Modern Stages

This essay investigates the extent to which girlhood functions as a queer category in two theatrical representations of schoolgirls in early seventeenth-century England. It focuses on the depictions of schoolgirls in the anonymous The Wit of a Woman (1604), written for the all-male stage of the professional theatre, and in Robert White’s masque, Cupid’s Banishment (1617), performed by the young Ladies of Deptford Hall before Queen Anna of Denmark, to examine the intersections of age, gender, sexuality and education in early modern concepts of girlhood. Situating these plays within wider debates about female education and the history of the contested role of performance in the schooling of early modern girls, it argues that they deploy the category of girlhood to demonstrate the subversive potential of educating girls. Yet, this essay proposes, these plays simultaneously reveal the potential agency of young women who manipulate girlhood to claim their distinct sexual, aged and gendered states as girls. It argues that early modern girlhood is a state that might be performed by young women to disrupt normative expectations of feminine behaviour and desire. Placing dramatic representations of schoolgirls and the experiences of schoolgirls on the early modern stage side by side, this essay demonstrates that the schoolroom and performance are sites in which this transgressive potential is realised.
