This study is part of a larger research project at the Image Permanence Institute dedicated to digital print preservation issues – the Digital Print Preservation Portal (DP3). Previous DP3 studies determined that certain digital print types are prone to cracking and/or abrasion, and that factors such as low relative humidity, pollutants, and light increase the brittleness of the ink-receiving layer of some inkjet papers. The purpose of this investigation was to explore if light also increases the propensity of inkjet prints to abrade, and to examine the potential of framing glazings to mitigate light-induced physical damage (cracking and abrasion) by attenuating some portion of the UV spectrum. Inkjet papers and prints were subjected to xenon lighting (to simulate daylight through window glass) without glazing, or in sealed framing packages with plain framing glass (soda-lime) or UV filtering glass. Before and after light exposure, brittleness, and abrasion resistance were evaluated independently using two tests: ISO 18907 (Imaging materials – Photographic films and papers – Wedge test for brittleness) and a rub test utilizing a Sutherland® Rub Tester. In this study, exposure to light increased the cracking and/or abrasion tendency of some specimens. The use of UV filtering glass reduced this light-induced propensity in all cases. Plain glass protected all samples from at least one of these two types of surface damage, but was less effective than UV glass. Light-induced brittleness and sensitivity to abrasion were mostly, though not exclusively, caused by UV radiation. It was also seen that some prints may become brittle and/or prone to abrasion in the absence of image fade. Budgeting the amount of light these objects can be exposed to, protecting them from UV radiation, and handling prints with caution especially after exhibition, is essential in order to limit physical damage. 相似文献
Background: School Health and Physical Education (HPE) and sport has increasingly become a complex cultural contact zone. With global population shifts, schools need policies and strategies to attend to the interests and needs of diverse student populations. School HPE and sport is a particularly significant site as it is a touchpoint for a range of cultural values and practices related to physical activity, the body, health and lifestyle proprieties.
Purpose: While there is a high Chinese student population in Australian schools, little research has been undertaken to understand their needs, experiences and perceptions in schools HPE and sport. In addition, research in the physical activity field is accentuated by paradigms that assume and perpetuate the binary notion of cultural beliefs and practices such as ‘West’ versus ‘East’ and in association with ‘Normal’ versus ‘Problematic’ lifestyles in relation to physical activity. We argue that, without conceding the epistemological understanding of ‘difference’, policies and practices that promote diversity can remain socially unjust and superficial.
Research design: This paper focuses on two schools in Queensland. The data collection process was underpinned by critical and interpretive ethnographic methods. The participants in Sage College consisted of seven girls of whom three were in Year 8, three in Year 9 and one in Year 10. At Routledge State High, a state-owned, secular and coeducational secondary school, the cohort consisted of two girls in Year 8, one girl and two boys from Year 9.
Results: This paper draws on Bourdieu's concepts of habitus, capital, field and doxa and the Chinese Confucianism philosophy of ‘Complementary difference’ to understand the various perceptions and experiences of young Chinese Australians in schools HPE and sport. Results invite us to seek an understanding of students’ subjectivities and disrupt the binary differences in cultural values and attributes to promote multicultural education.
Conclusion and recommendation: Moving beyond the Australia's Anglo-Celtic centred HPE and the limitations of a Western view of exclusive opposites, this paper makes an original contribution to knowledge by presenting a ‘heuristic of difference’ model that accommodates Western and Chinese perspectives in Australian HPE research. 相似文献
