This pilot study explores children's understanding of informed consent (IC) and the potential of participatory visual methods for improving the IC process. Strategies used to improve the IC process have generated mixed evidence as to their ability to increase understanding and willingness to participate among potential research participants. Two workshops with 13 children aged 8–12 years were held to discuss the content of IC forms, particularly confidentiality and voluntary participation, and the children took photographs to represent these concepts. Simplified written IC forms generated boredom, disengagement, and/or anxiety for some children. Preliminary results of this pilot study indicate the potential to enhance the IC process by using participatory visual methods with children to make visual IC forms. 相似文献

X光照相是一种传统的无损检测技术,广泛应用于各类文物的检测分析中。近年来,随着数字成像技术的逐步兴起,大大简化了X光照相的操作过程,得到的数字图像更容易观察、使用和存储,图像的编辑也成为可能。X光照相技术因此有了更大的发展空间。以一尊木雕造像为例,介绍了数字X光照相的操作过程,X光片经过编辑处理,最终得到了检测对象的X光照相三视图,并对其进行了分析和讨论。 相似文献

This article discusses the experience of using photography in a research project with young (prospective) migrants in Ghana and Italy. Photography can be an empowering research tool, one that offers young participants a degree of control over the research process and thus allows their points of view to emerge. However, researchers need to consider that the choice of subjects may be influenced by the children’s desire to avoid taking photographs in public, as they may attract attention and the act of pointing a camera may provoke unwanted questions and comments. Moreover, young people often lack the means to move independently, and this may further restrict the subjects they are able to photograph. Finally, they may resent adults’ intrusion into their free time and therefore see taking photographs as a chore. I argue that all these factors need to receive greater attention when choosing photography in research with young participants. 相似文献

AbstractThis paper will present research on the vulnerability mapping of coastal archaeological sites currently being undertaken in Northern Ireland. The ultimate aim of this research is improve current predictions of where archaeological sites and landscapes will be at risk in the future from coastal erosion. The initial stage of this approach uses a suite of oblique aerial photographs to construct a baseline of eroding locations and coastal geomorphology. The erosion baseline can then be integrated with existing historic environment records to obtain a coarse first-pass archaeological vulnerability assessment. Subsequent stages can then use this assessment to prioritize future mitigation such as field surveys or monitoring exercises, or conduct further refinements of vulnerability classifications by incorporating information on site type and positioning on a local scale. 相似文献

This paper discusses the way in which public photographic depictions of places and place-based communities contribute to the construction of local identity and community building. Being public and visualised statements about what a place and the people living there are and what they are not, photographs incite public debate about place and community. The paper discusses two interventions, one in Ghent, Belgium, involving professional photographers from outside the neighbourhood, and one in Bonnybridge, Scotland, involving amateur photography by local residents. Both are attempts by community workers to encourage citizens to discuss alternative realities of themselves, their neighbours and their neighbourhood. Starting from theories of place-making and public pedagogy, we reveal how both nonetheless exemplify very different strategies to democratise community-building processes. 相似文献

This paper offers a long-term reflection on the introduction of a photographic research project into a third-year undergraduate Human Geography module. The findings indicate that, whilst the students valued the project, it did impact on their overall performance, their evaluation of the module and the ways in which they spoke about it. The paper complements other discussions of photographic research methods in Human Geography by confirming their popularity and value to students' learning but argues that their introduction requires planning and reflection to mitigate some of the unintended consequences noted here and to maximize their benefits. 相似文献

Even though the sun has its peak emission of electromagnetic (EM) radiation in the visible waveband, it still produces a substantial amount of ultraviolet (UV) wavelengths (10–400 nm). However, the largest portion of this emitted energy is blocked by the ozone layer of the atmosphere, only allowing the near-ultraviolet or NUV (comprising the spectral band between 315 nm and 400 nm) to reach the earth's surface. Additionally, sensors acquiring this part of the UV wavelengths must be operated from low altitudes to minimize the effects of strong Rayleigh scattering to which the NUV radiation is subjected. Consequently, this waveband of the EM spectrum is rarely employed in aerial photography and its reflected portion only acquired in very specific applications. 相似文献

In 1910 Roger Casement was sent by the British government to investigate the alleged humanitarian abuses of the Peruvian Amazon Company in the Putumayo, a disputed border zone in North West Amazonia. Casement brought more than verbal and written testimony back to London. On 26 June, some six months after he returned from the Amazon, Casement collected two Amerindian boys – Omarino and Ricudo – from Southampton docks. This paper will reconstruct the brief period that these young men spent in Britain in the summer of 1911 and assess, in particular, to what extent they were treated as ‘exhibits’ by Casement, who not only introduced them to leading members of the British establishment but also arranged for them to be painted and photographed following contemporary ethnographic conventions. 相似文献

South Africans today inhabit a fragmented and discontinuous landscape, often despite their most cosmopolitan intentions. Grounded in the Coloured neighbourhood of Wentworth in Durban, this paper asks how remains of the past appear as differently temporalised artefacts, some buried in the archaic past and others more readily used to critique the present. In particular, I explore photographs of inmates of a concentration camp from 1902, township youth appropriating a specific commons in the early 1980s, black political photography from the late 1980s, and film wrestling with the ambiguities of post-apartheid political life in a Coloured neighbourhood next to an oil refinery. What unites these moments is not just a meta-theoretical concern with photography as both documentary and aesthetic, but the specific political uses of images, exemplified by the work of two black political photographers. Their practice provides cues for situating these other photographs in a long century of multiple dispossessions. The paper explores when and how photographs might shock the viewer into recognising resemblances, connections and potential solidarities, not just with the past, but with subaltern critique of racial space and subjectivity in the present. I suggest how we might view photographs from various moments relationally, to understand how, in one corner of contemporary South Africa, people continue to wait for justice despite uncertainty and official dissimulation, in a state of anticipatory frustration. 相似文献
