The emergence and organisation of amateur networks of observation in Britain in the period between 1920 and 1940 are addressed in this paper. It examines the geographical, organisational and epistemological associations between networks of ornithological observation (traced through the British Trust for Ornithology), which emerged from the 1920s, and amateur ethnography (traced through Mass-Observation) which emerged in the late 1930s. I approach these ‘observational cultures’ as spaces which brought together new concepts of the local, of everyday nature and society, as well as the possibilities of changing the everyday. The paper suggests that popular observation during the period partly constituted a reframing of ways of knowing Britain differentiated through the everyday production of natural and social knowledge and the construction of the active citizen and new communities of practice.  相似文献

The quantitative analysis of glass, ceramics and related silicate systems by means of energy dispersive X-ray fluorescence spectrometry is considered and problems arising from the selective absorption of X-rays in multi-element specimens are discussed. A computer programme written in FORTRAN and based upon a “semi-fundamental parameters” approach to the correction of matrix effects in glass and chemically similar materials is fully described. Model data are provided to enable the programme to be run and tested. An “empirical coefficients” computer programme for the quantitative analysis of silicate systems is outlined and the limitations of this type of programme are pointed out. The importance of adequate sample preparation prior to X-ray spectrometric analysis is stressed.  相似文献

Tom Stoppard is a playwright most noted for his ferocious wordplay and playful approach to reality. In the 1970s and 1980s, his concern for like-minded prisoners of conscience in the Soviet bloc informed his activism on their behalf, utilising his public profile in an attempt to reposition their plight in the West. Stoppard’s activism was largely informed by his involvement with a number of non-governmental organisations (NGOs) working to publicise human rights violations in the Soviet Union, who provided him with the most up to date information on these abuses, and gave him access to dissidents. This article explores Stoppard’s activism on behalf of Soviet prisoners of conscience, highlighting the impact that these organisations had on his activism. Through an assessment of Stoppard’s efforts, it highlights the important role that NGOs and celebrity politics played during the cold war.  相似文献

This paper opens up a dialogue between mindfulness and the discipline of geography. As a meditative practice that cultivates ‘present-centred non-judgmental awareness’, we claim that the practices and insights of mindfulness have important implications for various forms of geographical enquiry. This paper argues that mindfulness can inform geographical practices in relation to epistemology and methodology, and contribute towards geographically informed critical psychological theory and action. More specifically, we claim that mindfulness could offer a practice-based context to support the study of affects, extend the application of psychoanalytical geographical methods beyond the therapeutic, and contribute to emerging geographical studies of behavioural power and empowerment. This analysis explores these sites of interaction through a series of reflections on the Mindfulness, Behaviour Change and Engagement in Public Policy programme that was developed and delivered by the authors. This more-than-therapeutic mindfulness programme has been delivered to approximately 47 civil servants working in the UK Government.  相似文献

Studies of the ‘geographies of students’ have become increasingly prevalent across the social sciences and are particularly concerned with the predilection for young UK University undergraduates to be mobile in their institutional choice. A more recent focus within this work has been upon student identities, with attention given to how the spaces to which students move and in which they settle can have both positive and negative consequences for the evolution of the student identity, and how such identities are often framed within the context of social activities; learning environments; friendship networks; or other sociocultural factors. This paper contributes to these discussions by considering the role of student accommodation – a site which often remains on the periphery of discussions of student identities – in offering students opportunities to construct, adapt and manage their student identities. This adds to the important contemporary geographies of student accommodation, which are currently debating, among others, purpose-built student accommodation and the broad housing ‘careers’ and strategies of students. In contrast, this paper explores the micro-geographies of student accommodation (and more specifically, the bedroom) to highlight its value in providing young, mobile students with an anchor within which they can draw together their learner, social and domestic dispositions into one geographical location.  相似文献
