Blue and Red Cathodoluminescent Emission of Y2O3:Eu Phosphor Studied as a Function of Temperature in a Transmission Electron Microscope

Combined EELS, CL and STEM imaging are used to characterize and study Y2O3:Eu to confirm the variation in CL properties and photo-luminescent properties observed. The synthetic procedures used have facilitated this material to manifest a strong blue emission at low temperature with the expected red emission dominating at room temperature

Copyright and cultural work: an exploration

This article first discusses the contemporary debate on cultural “creativity” and the economy. Second, it considers the current state of UK copyright law and how it relates to cultural work. Third, based on empirical research on British dancers and musicians, an analysis of precarious cultural work is presented. A major focus is how those who follow their art by way of “portfolio” work handle their rights in ways that diverge significantly from the current simplistic assumptions of law and cultural policy. Our conclusions underline the distance between present top-down conceptions of what drives production in the cultural field and the actual practice of dancers and musicians

Nano-cathodoluminescence reveals the effect of electron damage on the optical properties of nitride optoelectronics and the damage threshold

Nano-cathodoluminescence (Nano-CL) reveals optical emission from individual InGaN quantum wells for applications in optoelectronic devices. We show the luminescent intensity decays over time with exposure to the electron beam for energies between 80 and 200 keV. Measurements of the CL intensity over time show an exponential decline in intensity, which we propose is due to the formation of nitrogen Frenkel defects. The measured CL damage decreases with reductions in the electron accelerating voltage and we suggest that the electron induced structural damage may be suppressed below the proposed damage threshold. The electron beam induced damage leads to a non-radiative region that extends over the measured minority carrier diffusion length. Nano-CL may thus serve as a powerful technique to study III-nitride optoelectronics.This work was carried out with the support of the United Kingdom Engineering and Physical Sciences Research Council under Grant Nos.

Superhuman? Perceptions of accelerated students and graduates working in health care

Background: Accelerated university courses were developed in response to consumer demand and educational advances, yet a lack of research exists related to the impact of accelerated health care courses in the United Kingdom. Objectives: This study explored clinicians' perceptions of accelerated pre-registration courses in physiotherapy. Method: Senior clinicians were recruited by purposive sampling from several National Health Service hospitals across northeast England. Data from face-to-face semi-structured interviews were recorded, transcribed verbatim and analysed using Interpretive Phenomenological Analysis. Findings: Findings from fourteen participants indicated their admiration of accelerated students’ attributes to complete what they considered to be an intense and in-depth course. Such graduates were described as ‘superhuman.’ Participants noted that accelerated graduates were likely to ‘hit the ground running’ in clinical settings. However, concerns were raised that some accelerated graduates' over-confidence affected team dynamics and/or affected some aspects of clinical reasoning. Conclusions: Participants valued the varied routes to graduation while recognising their strengths and limitations. Findings from the study suggested the need for different types of clinical supervision to support each route

Moebius strip enterprises and expertise in the creative industries: new challenges for lifelong learning?

The paper argues that the emergence of a new mode of production – co-configuration is generating new modes of expertise that EU policies for lifelong learning are not designed to support professionals to develop. It maintains that this change can be seen most clearly when we analyse Small and Medium Size (SMEs) enterprises in the creative industries. Drawing on concepts from Political Economy - ‘Moebius strip enterprise/expertise’ and Cultural Historical Activity Theory - project-object’ and the ‘space of reasons’, the paper highlights conceptually and through a case study of an SME in the creative industries what is distinctive about the new modes of expertise, before moving on to reconceptualise expertise and learning and to consider the implications of this reconceptualisation for EU policies for lifelong learning. The paper concludes that the new challenge for LLL is to support the development of new forms expertise that are difficult to credentialise, yet, are central to the wider European goal of realising a knowledge economy

Using a meta-ethnographic approach to explore the nature of facilitation and teaching approaches employed in interprofessional education.

BACKGROUND: Interprofessional facilitators and teachers are regarded as central to the effective delivery of interprofessional education (IPE). As the IPE literature continues to expand, most studies have focused on reporting learner outcomes, with little attention paid to IPE facilitation. However, a number of studies have recently emerged reporting on this phenomenon. AIM: To present a synthesis of qualitative evidence on the facilitation of IPE, using a meta-ethnographic approach. METHODS: Electronic databases and journals were searched for the past 10 years. Of the 2164 abstracts initially found, 94 full papers were reviewed and subsequently 12 papers were included. Teams of two reviewers independently completed each step in the review process. The quality of these papers was assessed using a modified critical appraisal checklist. RESULTS: Seven key concepts embedded in the included studies were synthesized into three main factors which provided an insight into the nature of IPE facilitation. Specifically, the synthesis found that IPE facilitation is influenced by "contextual characteristics"; "facilitator experiences"; and the "use of different facilitation strategies". CONCLUSIONS: IPE facilitation is a complex activity affected by contextual, experiential and pedagogical factors. Further research is needed to explore the effects of these factors on the delivery of IPE
