Teacher decision making in further education.

Teachers' decision making is a crucial element in the quality of delivery of teaching and learning and, therefore, of educational outcomes in the form of student performance. There is, however, a dearth of relevant studies in this area, especially in the F. E. sector. This study sets out to investigate the practice of teachers' decision making in the substantive context of the Further Education sector in Scotland. The investigation adopted two main approaches: firstly, an interpretive approach,in which qualitative and quantitative methods were combined to collect and analyse data by the protocols of individual interviews, case studies and questionnaires: secondly, a developmental approach involved the application throughout of constant comparative analysis,in the tradition of "grounded theory". The population of the study, the source of both qualitative and quantitative data, was made up of 145 practitioner- subjects, drawn from a range of subject specialisms and approximately evenly split in terms of gender. The qualitative data,when statistically analysed permitted comparisons of the responses of the subjects to be made in terms of major subject specialisms in their teaching,and also in terms of gender. The major conceptual and theoretical outcome is a descriptive model of the practice of teachers' decision making, developed on the basis of subsidiary outcomes: a new, operational definition of decision. an innovative typology of decisions; an original way of categorising decisions by their content or substance. The developed versions of these outcomes constitute the major findings of the research. Recommendations include: potential applications of the outcomes of the study; possible research routes to further development of the conceptual findings presented. The boundaries and limitations of the study are also described and discussed

Symptomatic Social Science: Reflexivity, Recognition and Redistribution in the GBCS

The article examines methodological and theoretical issues related to the GBCS. It acknowledges its importance for the public profile of sociology, whilst arguing that it needs to develop a better sense of what it stands for not only in terms of understanding societal changes, but contributing to human betterment. To achieve this it discusses the role of reflexivity in the GBCS with reference to position and disposition and accounts of its process. It then moves on to examine its normative basis in terms of an ‘existential analytics’ and suggests a series of ways in which it might advance its insights as the work develops

A machine-hearing system exploiting head movements for binaural sound localisation in reverberant conditions

This paper is concerned with machine localisation of multiple active speech sources in reverberant environments using two (binaural) microphones. Such conditions typically present a problem for `classical' binaural models. Inspired by the human ability to utilise head movements, the current study investigated the influence of different head movement strategies on binaural sound localisation. A machine-hearing system that exploits a multi-step head rotation strategy for sound localisation was found to produce the best performance in simulated reverberant acoustic space. This paper also reports the public release of a free binaural room impulse responses (BRIRs) database that allows the simulation of head rotation used in this study

Critical values of a kernel density-based mutual information estimator

Copyright © 2006 IEEERecently, mutual information (MI) has become widely recognized as a statistical measure of dependence that is suitable for applications where data are non-Gaussian, or where the dependency between variables is non-linear. However, a significant disadvantage of this measure is the inability to define an analytical expression for the distribution of MI estimators, which are based upon a finite dataset. This paper deals specifically with a popular kernel density based estimator, for which the distribution is determined empirically using Monte Carlo simulation. The application of the critical values of MI derived from this distribution to a test for independence is demonstrated within the context of a benchmark input variable selection problem.http://www.okstate.edu/elec-engr/faculty/yen/wcci/WCCI-Web_ProgramList_F.htm

Rethinking the patient: using Burden of Treatment Theory to understand the changing dynamics of illness

<b>Background</b> In this article we outline Burden of Treatment Theory, a new model of the relationship between sick people, their social networks, and healthcare services. Health services face the challenge of growing populations with long-term and life-limiting conditions, they have responded to this by delegating to sick people and their networks routine work aimed at managing symptoms, and at retarding - and sometimes preventing - disease progression. This is the new proactive work of patient-hood for which patients are increasingly accountable: founded on ideas about self-care, self-empowerment, and self-actualization, and on new technologies and treatment modalities which can be shifted from the clinic into the community. These place new demands on sick people, which they may experience as burdens of treatment.<p></p> <b>Discussion</b> As the burdens accumulate some patients are overwhelmed, and the consequences are likely to be poor healthcare outcomes for individual patients, increasing strain on caregivers, and rising demand and costs of healthcare services. In the face of these challenges we need to better understand the resources that patients draw upon as they respond to the demands of both burdens of illness and burdens of treatment, and the ways that resources interact with healthcare utilization.<p></p> <b>Summary</b> Burden of Treatment Theory is oriented to understanding how capacity for action interacts with the work that stems from healthcare. Burden of Treatment Theory is a structural model that focuses on the work that patients and their networks do. It thus helps us understand variations in healthcare utilization and adherence in different healthcare settings and clinical contexts

‘Stressed, uncomfortable, vulnerable, neglected’: a qualitative study of the psychological and social impact of the COVID-19 pandemic on UK frontline keyworkers

Objectives: Non-healthcare keyworkers face distinct occupational vulnerabilities that have received little consideration within broader debates about ‘essential’ work and psychological distress during the COVID-19 pandemic. The aim of this study was therefore to explore the impact of the pandemic on the working lives and mental health and well-being of non-healthcare keyworkers in the UK. Design: In-depth, qualitative interviews, analysed using a reflexive thematic analysis. Setting: Telephone or video call interviews, conducted in the UK between September 2020 and January 2021. Participants: 23 participants aged 26–61 (mean age=47.2) years employed in a range of non-healthcare keyworker occupations, including transport, retail, education, postal services, the police and fire services, waste collection, finance and religious services. Results: Keyworkers experienced adverse psychological effects during the COVID-19 pandemic, including fears of COVID-19 exposure, contagion and subsequent transmission to others, especially their families. These concerns were often experienced in the context of multiple exposure risks, including insufficient personal protective equipment and a lack of workplace mitigation practices. Keyworkers also described multiple work-related challenges, including increased workload, a lack of public and organisational recognition and feelings of disempowerment. Conclusions: In efforts to reduce psychosocial concerns among non-healthcare keyworkers, there is a need for appropriate support during the COVID-19 pandemic and in preparation for other infections (eg, seasonal influenza) in the future. This includes the provision of psychological and workplace measures attending to the intersections of personal vulnerability and work conditions that cause unique risks and challenges among those in frontline keyworker occupations

Non-Markovian quantum state diffusion for absorption spectra of molecular aggregates

In many molecular systems one encounters the situation where electronic excitations couple to a quasi-continuum of phonon modes. That continuum may be highly structured e.g. due to some weakly damped high frequency modes. To handle such a situation, an approach combining the non-Markovian quantum state diffusion (NMQSD) description of open quantum systems with an efficient but abstract approximation was recently applied to calculate energy transfer and absorption spectra of molecular aggregates [Roden, Eisfeld, Wolff, Strunz, PRL 103 (2009) 058301]. To explore the validity of the used approximation for such complicated systems, in the present work we compare the calculated (approximative) absorption spectra with exact results. These are obtained from the method of pseudomodes, which we show to be capable of determining the exact spectra for small aggregates and a few pseudomodes. It turns out that in the cases considered, the results of the two approaches mostly agree quite well. The advantages and disadvantages of the two approaches are discussed

The Adelaide VHF radar: Capabilities and future plans

The VHF radar at Buckland Park, South Australia commenced operation in January, 1984. The radar is located adjacent to the 2-MHz ionospheric radar. The routine method for measuring horizontal wind velocity is the space antenna technique (SA) while the Doppler technique is used to measure vertical velocities. It is possible to swing the transmitting beam in the east-west plane, allowing Doppler measurements of the EW wind component
