Not through confusion or fear: motivational approaches for preparing Physician Associate students for post graduate study and beyond.

This is an accepted manuscript of an article published by University of Wolverhampton in Pedagogy in Practice in November 2016, available online: http://ejournal.ewlv.org/?attachment_id=101 The accepted version of the publication may differ from the final published version.This review paper explores the underlying principles of motivating Physician Associate students during both matriculation and progression points of post-graduate study. Pertinent notions of the teacher student relationship and its complexities are examined against the literature, aligned to constructionist learning theories. The impact of such motivational expressions by Higher Education teachers sets the scene for future approaches to deep learning that can impact upon safe and compassionate clinical practice. Educational novices are viewed to be in the ideal position within Higher Education and external stakeholders to explore and design an articulated curriculum that is fit for the 21st century healthcare economies. The correlation between effective motivation and enthusiasm is considered in line with student experiences and expectations resulting in safe effective patient care. The paper suggests that Higher Education teachers would better meet student expectations with more awareness of student entry level behaviour

Early Help Mechanisms – A Mere Fad Or A Ground Breaking Reformation To Child Protection Systems?

Early intervention and preventative work with children, young people and families is not a new phenomenon. It is authenticated, for example, through the introduction of Sure Start Local Area programmes which were initially established between 1999 and 2002 to support families with children aged 0-4 who resided in areas of disadvantage. Initially, 524 dedicated built children centres were established with a further 3,500 developed from 2007 onwards. Their core purpose (DE, 2012) provides outreach facilities, integrated early education, parenting programmes, child care and health care and family support services through early intervention, thus formally enshrining the professional relationships between the disciplines of health and education (Williams and Churchill, 2006)

The null energy condition and instability

We extend previous work showing that violation of the null energy condition implies instability in a broad class of models, including gauge theories with scalar and fermionic matter as well as any perfect fluid. Simple examples are given to illustrate these results. The role of causality in our results is discussed. Finally, we extend the fluid results to more general systems in thermal equilibrium. When applied to the dark energy, our results imply that w is unlikely to be less than -1.Comment: 11 pages, 5 figures, Revte

Zero Temperature Insulator-Metal Transition in Doped Manganites

We study the transition at T=0 from a ferromagnetic insulating to a ferromagnetic metallic phase in manganites as a function of hole doping using an effective low-energy model Hamiltonian proposed by us recently. The model incorporates the quantum nature of the dynamic Jahn-Teller(JT) phonons strongly coupled to orbitally degenerate electrons as well as strong Coulomb correlation effects and leads naturally to the coexistence of localized (JT polaronic) and band-like electronic states. We study the insulator-metal transition as a function of doping as well as of the correlation strength U and JT gain in energy E_{JT}, and find, for realistic values of parameters, a ground state phase diagram in agreement with experiments. We also discuss how several other features of manganites as well as differences in behaviour among manganites can be understood in terms of our model.Comment: To be published in Europhysics Letter

Ultrahigh Bandwidth Spin Noise Spectroscopy: Detection of Large g-Factor Fluctuations in Highly n-Doped GaAs

We advance all optical spin noise spectroscopy (SNS) in semiconductors to detection bandwidths of several hundred gigahertz by employing an ingenious scheme of pulse trains from ultrafast laser oscillators as an optical probe. The ultrafast SNS technique avoids the need for optical pumping and enables nearly perturbation free measurements of extremely short spin dephasing times. We employ the technique to highly n-doped bulk GaAs where magnetic field dependent measurements show unexpected large g-factor fluctuations. Calculations suggest that such large g-factor fluctuations do not necessarily result from extrinsic sample variations but are intrinsically present in every doped semiconductor due to the stochastic nature of the dopant distribution.Comment: 5 pages, 3 figure

Evidence for charge localization in the ferromagnetic phase of La_(1-x)Ca_(x)MnO_3 from High real-space-resolution x-ray diffraction

High real-space-resolution atomic pair distribution functions of La_(1-x)Ca_(x)MnO_3 (x=0.12, 0.25 and 0.33) have been measured using high-energy x-ray powder diffraction to study the size and shape of the MnO_6 octahedron as a function of temperature and doping. In the paramagnetic insulating phase we find evidence for three distinct bond-lengths (~ 1.88, 1.95 and 2.15A) which we ascribe to Mn^{4+}-O, Mn^{3+}-O short and Mn^{3+}-O long bonds respectively. In the ferromagnetic metallic (FM) phase, for x=0.33 and T=20K, we find a single Mn-O bond-length; however, as the metal-insulator transition is approached either by increasing T or decreasing x, intensity progressively appears around r=2.15 and in the region 1.8 - 1.9A suggesting the appearance of Mn^{3+}-O long bonds and short Mn^{4+}-O bonds. This is strong evidence that charge localized and delocalized phases coexist close to the metal-insulator transition in the FM phase.Comment: 8 pages, 8 postscript figures, submitted to Phys. Rev.

Synthesis of super bright indium phosphide colloidal quantum dots through thermal diffusion

Indium phosphide based quantum dots have emerged in recent years as alternatives to traditional heavy metal (cadmium, lead) based materials suitable for biomedical application due to their non-toxic nature. The major barrier to this application, is their low photoluminescent quantum yield in aqueous environments (typically < 5%). Here we present a synthetic method for InP/ZnS quantum dots, utilizing a controlled cooling step for equilibration of zinc sulfide across the core, resulting in a photoluminescent quantum yield as high as 85% in organic solvent and 57% in aqueous media. To the best of our knowledge, this is the highest reported for indium phosphide quantum dots. DFT calculations reveal the enhancement in quantum yield is achieved by redistribution of zinc sulfide across the indium phosphide core through thermal diffusion. By eliminating the need for a glove box and relying on Schlenk line techniques, we introduce a widely accessible method for quantum dots with a realistic potential for improved biomedical applications

Building local capacity in the arts

© 2016 Informa UK Limited, trading as Taylor & Francis GroupThe importance of place-based funding and local policy initiatives is evident in policy literature internationally with concepts of creative cities and cultural regeneration building in prominence since the 1990s. Such literature makes the case that investment in arts and culture will bring broader social and economic benefits at a local level, but in practice investment and research has prioritised a small number of metropolitan arts venues and mega events over a larger rural or community-based infrastructure. This paper in contrast explores two case studies of cultural planning in small towns. It analyses the relationship between policy and practice in these specific community contexts and considers the role of participatory decision-making in developing a local arts infrastructure. The findings suggest that locally based initiatives can build capacity and engagement with the arts. But it further argues that this requires long-term commitment and investment, to facilitate shared decision-making between professionals and public
