A partial differential equation for pseudocontact shift
No full textIt is demonstrated that pseudocontact shift (PCS), viewed as a scalar or a tensor field in three dimensions, obeys an elliptic partial differential equation with a source term that depends on the Hessian of the unpaired electron probability density. The equation enables straightforward PCS prediction and analysis in systems with delocalized unpaired electrons, particularly for the nuclei located in their immediate vicinity. It is also shown that the probability density of the unpaired electron may be extracted, using a regularization procedure, from PCS data

THE PLACE FROM WHICH I SEE: a practice-led investigation into the role of vision in understanding solo performance improvisation as a form of composition.
No full textThe Place From Which I See is a practice-led investigation into performance improvisation in which I have asked the question: ‘What is the role of vision in understanding solo performance improvisation as a form of composition?’ The research is encompassed and presented in two different, but interwoven, modalities, which function as a total thesis. These are: (1) a written thesis, which is divided into the four main chapters outlined in the Introduction and (2) a sharing of studio-based investigations and performances - included on the accompanying DVD - and a live performance. This sharing of practical work is designed to illuminate how the practice has functioned as a methodology for research and as a means of embodying and making public the research outcomes. Together, it is intended that these different articulations form a clear and useful prism through which the practical and theoretical terrain of the project can be distilled.
In this thesis I argue that working pragmatically and creatively with vision within the specificity of the immediate space and situation of performance can function as an efficacious means of understanding solo improvised performance as a form of composition, and the research offers five strategies that collectively function as a template of approaches for generating and shaping improvisational material. The strategies have been developed through instigating a practice/theory feedback loop with the phenomenology and artistic paradigm offered by French philosopher Maurice Merleau-Ponty. I introduce his model of painterly composition as a particular rubric of what I call vision/action responsiveness against which I situate my own compositional approaches. I also outline five of the key ideas that infuse both this rubric and his phenomenology more generally - the significance of the entwining of a ‘questioning’ vision with movement; the chiasm; the visible; the ‘invisible’ and the ‘I can’ - and illuminate the way in which the practice has been developed and refined through a pragmatic interaction with these ideas. The thesis also outlines how these aspects of the phenomenological discourse have been re-framed through this interaction with the practical investigations and I situate my working of Merleau-Ponty’s ideas within the context of other treatments within both dance and theatre. More broadly, I relate this doctorate’s methodological approach and aesthetic concern with vision as a core compositional tool in and for performance to the compositional strategies, aesthetics, methodologies and philosophies of a range of other practitioners, locating the research within the wider field of improvisational performance. As an outcome, this research offers the template of strategies, layered with my particular re-framings of Merleau-Ponty’s phenomenology, as an original contribution to the practice and discourse of solo performance improvisation
SDG 13 and the entwining of climate and sustainability metagovernance:an archaeological-genealogical analysis of goals-based climate governance
No full textPurpose – This paper brings insights from accounting scholarship to the measurement and reporting challenges of metagovernance approaches to sustainable development. Where scholarship on metagovernance—the combination of market, hierarchical and network governance—proposes deductive approaches to such challenges, we contend that a historically-informed ‘abductive’ approach offers valuable insight into the realpolitik of intergovernmental frameworks.Design/methodology/approach – The paper adopts a Foucauldian ‘archaeological-genealogical’ method to investigate the inclusion of climate change as a Sustainable Development Goal (SDG). It analyses more than 100 documents and texts, tracking the statement forms that crystallise prevailing truth claims across the development of climate and SDG metagovernance.Findings – We show how the truth claims now enshrined in the Paris Agreement on Climate Change constrained the conceptualisation and operationalisation of SDG 13: Take urgent action to combat climate change and its impacts. The paper thereby reframes recent measurement and reporting challenges as outcomes of conceptual conflicts between the technicist emphasis of divisions within the United Nations and the truth claims enshrined in intergovernmental agreements. Originality/value – This paper demonstrates how an archaeological-genealogical approach may start to address the measurement and reporting challenges facing climate and SDG metagovernance. It also highlights that the two degrees target on climate change has a manifest variability of interpretation and shows how this characteristic has become pivotal to operationalising climate metagovernance in a manner that respects the sovereignty of developing nations.<br/
The Space of International Political Economy: On Scale and its Limits
No full textThis article introduces the contribution made by scholars writing on the 'new political economy of scale'. It explains how this approach shares with neo-Gramscian approaches a concern with challenging the problematic assumptions of much international political economy theorising. Moreover, if the achievement of scholars such as Robert Cox has been to show how social forces shape and reshape world orders over time, then the new political economy of scale also reveals how social forces do not simply operate within and across national state space, but also politicise space itself. The final part of the article reviews two sets of criticisms of the approach and concludes that, while it has been significant in challenging IPE scholars to reflect upon their spatial assumptions, its status as a critical alternative may well be compromised by its own foundational tenets. © 2010 The Author.

Challenging New State Spatialities: The Open Marxism of Henri Lefebvre
No full textIt is possible to identify a subterranean tradition within Marxism-one in which dialectical thought is harnessed not only to expose the necessarily exploitative and inherently crisis-prone character of capitalism as an actual system of social organisation, but also to critique the very categories that constitute capitalism as a conceptual system. This paper argues that Henri Lefebvre's work can be included within this tradition of "open Marxism". In demonstrating how Lefebvre's work on everyday life, the production of space and the state derives from his open approach, the paper flags a potential problem of antinomy in an emergent new state spatialities literature that draws upon Lefebvre to supplement its structuralist-regulationist ("closed") Marxist foundations. A Lefebvre-inspired challenge is therefore established: that is, to develop a critique of space which does not substitute an open theory of the space of political economy with a closed theory of the political economy of the regulation of space. © 2010 The Author Journal compilation © 2010 Editorial Board of Antipode
An Ethnography of the Ecology of Applied Sport Psychology Practice in English Professional Youth Football
No full textThe thesis outlines a research project that was undertaken by a practitioner-researcher operating in an elite youth academy full-time in a professional football club. The author conducted an ethnography to critically explore the role and function of an applied sport psychology practitioner in a Category 1 Premier League academy. Throughout the PhD research, the practitioner-researcher was responsible for the delivery of a psychological development programme to youth athletes aspiring to become professional footballers. The data on which the thesis was based was drawn from multiple methods including observation, field notes, individual interviews, and focus groups. The incredibly complex role of the practitioner-researcher in the professional football club is outlined and an authentic account of their day-to-day existence in the environment is provided. Key events over a longitudinal period are discussed to inform an ecological approach to sport psychology provision in the football academy. The research was conducted via a critical lens in which the research not only described experiences as a practitioner-research but ultimately helped to inform a ecologically informed approach to psychology services at the football club. The thesis aimed to close the ‘gap’ between theory and practice and provide a more realistic and authentic picture of applied sport psychology practice at the coalface in a professional football club. The thesis provides insight into the importance of successfully gaining entry into elite football clubs and how micropolitical literacy is necessary to practice effectively in such settings. Furthermore, the preparedness, professional training and supervision of trainees is discussed to better prepare young practitioners seeking to work in the world of football
Update Offshore Wind Atlas: Implementing a variable sea surface roughness
No full textIn 2005 the Energy research Centre of the Netherlands (ECN) published its first version of the Offshore Wind Atlas of the Dutch part of the North Sea [3]. This version has been updated and improved using longer time series and another approach for the calculation of the roughness of the sea surface. In contradiction to other Wind Atlases which are based on measurements [28], use is made of data from the Numerical Weather Prediction model Hirlam. Measurements of wind speeds and directions are only used to validate the Wind Atlas. For the Offshore Wind Atlas, the Hirlam data is interpolated where for the vertically interpolation use is made of the Businger-Dyer profiles in combination with the Monin-Obukhov length [3]. One of the required parameters for the interpolation is the surface roughness. For land, it can be assumed constant while for sea it is variable. In the previous version of the Offshore Wind Atlas, the sea surface roughness has been determined using Charnock’s relation [9], where the so-called Charnock parameter is constant. In the new version, the equation of Hsu is introduced which states that the Charnock parameter is variable and dependent on the wave steepness i.e. the wave height divided by the wave length [19]. Assuming that the North Sea is a shallow sea and using the general wave equation, which relates the sea depth and wave length to the phase velocity of the waves, it was found that the wave steepness can be rewritten in a fraction of the wave height over the wave period multiplied by the square root of the sea depth times the gravitational acceleration. These quantities are derived from measured values which are interpolated to the location of interest. Using this approach, it is tried to improve the prediction of the wind speed distributions for a given location and altitude. Using wind measurements at several locations it was found that adding the wave data to the computations show a small improvement in the estimation of the wind speed distribution compared to the previous version of the Offshore Wind Atlas. For each measurement location and method, a two parameter Weibull distribution has been made, after which a comparison was done between the various shape and scale parameters. Generally, the scale parameter was overestimated by both versions of the Offshore Wind Atlas compared to the measurements. The cause of this behavior might be found in the data used to make the Atlas. The shape parameter is well predicted by the new version of the Offshore Wind Atlas due to the use of wave data. The influence of the wave data is found to be larger for lower altitudes than for higher altitudes. Besides Weibull distributions, also maps with average wind speeds are given by the Offshore Wind Atlas which are compared to older maps.Aerospace Engineerin
