    Predictive use of the Maximum Entropy Production principle for Past and Present Climates

    In this paper, we show how the MEP hypothesis may be used to build simple climate models without representing explicitly the energy transport by the atmosphere. The purpose is twofold. First, we assess the performance of the MEP hypothesis by comparing a simple model with minimal input data to a complex, state-of-the-art General Circulation Model. Next, we show how to improve the realism of MEP climate models by including climate feedbacks, focusing on the case of the water-vapour feedback. We also discuss the dependence of the entropy production rate and predicted surface temperature on the resolution of the model

    No measure for culture? Value in the new economy

    This paper explores articulations of the value of investment in culture and the arts through a critical discourse analysis of policy documents, reports and academic commentary since 1997. It argues that in this period, discourses around the value of culture have moved from a focus on the direct economic contributions of the culture industries to their indirect economic benefits. These indirect benefits are discussed here under three main headings: creativity and innovation, employability, and social inclusion. These are in turn analysed in terms of three forms of capital: human, social and cultural. The paper concludes with an analysis of this discursive shift through the lens of autonomist Marxist concerns with the labour of social reproduction. It is our argument that, in contemporary policy discourses on culture and the arts, the government in the UK is increasingly concerned with the use of culture to form the social in the image of capital. As such, we must turn our attention beyond the walls of the factory in order to understand the contemporary capitalist production of value and resistance to it. </jats:p

    Postgraduate education for Chinese medicine practitioners: a Hong Kong perspective

    &lt;b&gt;Background&lt;/b&gt; Despite Hong Kong government's official commitment to the development of traditional Chinese medicine (TCM) over the last ten years, there appears to have been limited progress in public sector initiated career development and postgraduate training (PGT) for public university trained TCM practitioners. Instead, the private TCM sector is expected to play a major role in nurturing the next generation of TCM practitioners. In the present study we evaluated TCM graduates' perspectives on their career prospects and their views regarding PGT.&lt;p&gt;&lt;/p&gt; &lt;b&gt;Method&lt;/b&gt; Three focus group discussions with 19 local TCM graduates who had worked full time in a clinical setting for fewer than 5 years. &lt;p&gt;&lt;/p&gt; &lt;b&gt;Results&lt;/b&gt; Graduates were generally uncertain about how to develop their career pathways in Hong Kong with few postgraduate development opportunities; because of this some were planning to leave the profession altogether. Despite their expressed needs, they were dissatisfied with the current quality of local PGT and suggested various ways for improvement including supervised practice-based learning, competency-based training, and accreditation of training with trainee involvement in design and evaluation. In addition they identified educational needs beyond TCM, in particular a better understanding of western medicine and team working so that primary care provision might be more integrated in the future. &lt;p&gt;&lt;/p&gt; &lt;b&gt;Conclusion&lt;/b&gt; TCM graduates in Hong Kong feel let down by the lack of public PGT opportunities which is hindering career development. To develop a new generation of TCM practitioners with the capacity to provide quality and comprehensive care, a stronger role for the government, including sufficient public funding, in promoting TCM graduates' careers and training development is suggested. Recent British and Australian experiences in prevocational western medicine training reform may serve as a source of references when relevant program for TCM graduates is planned in the futur

    Time, the Written Record, and Professional Practice: The Case of Contemporary Social Work

    Get PDF
    Drawing on a three year ethnographically-oriented study exploring contemporary professional social work writing, this paper focuses on a key concern: the amount of time taken up with writing, or ‘paperwork’. We explore the relationship between time and professional social work writing in three key ways. Firstly, as a discrete, measurable phenomenon - how much time is spent on writing? Secondly, as a textual dimension to social work writing – how do institutional documents drive particular entextualisations of time and how do social worker texts entextualise time? Thirdly, as a particular timespace configuration of lived experience - how is time experienced by professional social workers? Findings indicate that a dominant institutional chronotope is governing social work textual practice underpinned by an ideology of writing which is at odds with social workers’ desired practice and professional goals. Methodologically, the paper illustrates the value of combining a range of data and analytic tools, using textual and contextual data, as well as qualitative and quantitative frames of analysis

    Development of YLM, a codominant PCR marker closely linked to the Yd2 gene for resistance to barley yellow dwarf disease

    No full text
    The Yd2 gene in barley provides protection against barley yellow dwarf luteovirus (BYDV), the most economically devastating virus of cereals worldwide. Because resistance assays to identify Yd2-containing individuals from breeding populations are often difficult, we have developed a closely linked, codominant PCR-based marker for Yd2 using AFLP marker technology. The marker, designated YLM, can be amplified from barley genomic DNA prepared using a rapid and simple extraction procedure and, in a survey of more than 100 barley genotypes, was found to be polymorphic between most Yd2 and non-Yd2 lines. The YLM therefore shows excellent potential as a tool for selecting Yd2-carrying segregants in barley breeding programmes.Paltridge, N. G. ; Collins, N. C. ; Bendahmane, A. ; Symons, R. H

    Functional genomics of abiotic stress tolerance in cereals

    No full text
    Abiotic stresses such as extreme temperatures, low water availability, high salt andmineral deficiencies or toxicities severely diminish productivity of cereal crops. These stresses are becoming increasingly important because of the declining availability of good quality water, land degradation and community pressures to move away from chemical intervention in agriculture.Of the major cereals, wheat and barley are grown in the most hostile and consequently lowest yielding environments. Extensive genetic studies and surveys of landrace and wild germplasm have indicated extensive variation for abiotic stress tolerance but this has been difficult to exploit due to the relatively poor background knowledge of the molecular basis for stress in these species. Interconnected signal transduction pathways that lead to multiple responses to abiotic stresses have been difficult to study using traditional approaches because of their complexity and the large number of genes and gene products involved in the various defensive and developmental responses of the plant. Functional genomics is now widely seen as providing tools for dissecting abiotic stress responses in wheat and barley, through which networks of stress perception, signal transduction and defensive responses can be examined from gene transcription, through protein complements of cells, to the metabolite profiles of stressed tissues
