ABSTRACTPreventive conservation, with its origins grounded in the material fabric of cultural material, is in a period of transformation, with numerous practitioners, in and outside of the field of conservation, considering its broader and holistic objectives. The conventional tools for the assertion of preventive conservation principles, namely the assessment and management of risks to cultural material from the ‘ten agents of deterioration’, have a central focus on the primacy of physical materials and degradation, with less clear relationships with people, place, and time in their modelling. With a case study focus on collections in the Philippines, this paper argues for a practice of preventive conservation that incorporates a balanced assessment and broader thinking around the contexts of objects, people, place, and time. The case studies of ecclesiastical Church collections, and museum environments in the Philippines, demonstrate how the interdependency of objects, people, place and time forms a holistic and conceptual preventive conservation framework. Through a cyclic renegotiation of these four parameters, this paper speculates on the gaps and opportunities for an inclusive view of preventive conservation that is current and more sustainable. 相似文献

This paper builds upon previous research that examines participatory forms of “reciprocal journalism” and “public communication” led by high school and college students in Miami, Florida, USA, in the fall of 2014. In this study, the students’ assessment of local and national media coverage is used to reveal greater details inherent in examining participatory methods of newswork. Collectively, students said that media coverage emphasis on local and national public officials instead of residents and community members who experience sea-level rise first-hand, combined with a lack of scientific explanation of and solutions for sea-level rise reduced the event's potential to build reciprocal relationships with younger audiences. 相似文献

This study investigated interpersonal coordination tendencies in 1vs.1 dyads in rugby union, here expressed by participants' movement velocity towards or away from the sideline as they competed to score or prevent a try. We examined whether coupling tendencies of members of each dyad shaped key performance outcomes (try or successful tackle). Data on movement displacement trajectories of eight male rugby union players (aged 11–12 years) were analysed during performance in 47 trials. To assess coordination tendencies during exploratory behaviours in the dyads, analyses of performance time series data were undertaken using variable time graphs, running correlations and cross-correlations. Results revealed distinct coupling patterns characterised by shifts between synchronous coordination and asynchronous coordination tendencies and uncoordinated actions. Observed behaviours were interpreted as attempts of competing participants to create and perceive possibilities for action while seeking to achieve specific performance goals. Findings also revealed that a variety of patterned relations between participants resulted in different performance outcomes. 相似文献

The app for the System for Observing Play and Recreation in Communities (iSOPARC®) was developed to enhance System for Observing Play and Recreation in Communities data collection and management. The study aim was to examine the usability and inter-rater reliability of iSOPARC®. Trained observers collected data in 16 park areas in two Latin America cities (Curitiba, Brazil; Bogotá, Colombia) using both the original System for Observing Play and Recreation in Communities (mechanical counter) and new iSOPARC® (electronic counter) methods. A total of 8,707 park users (3,958 females and 4,749 males) were observed. Reliabilities among observers were determined using the intraclass correlation coefficient and relative overall agreement (%) in three ways: (a) mechanical versus mechanical, (b) mechanical versus electronic, and (c) electronic versus electronic. When both used mechanical counters comparisons overall agreement was over 78% (intraclass correlation coefficient = .982; p < .001) for variables in all analysis. When one used a mechanical counter and the other used electronic (iSOPARC®) comparisons overall agreement was higher for age (84%; p < .001) than for physical activity (83%; p < .001) variables and average intraclass correlation coefficient was .965. Using both used iSOPARC® comparisons overall agreement was 81% to physical activity and 83% to age group. Results suggest iSOPARC® can be used reliably for examining variables previously validated in System for Observing Play and Recreation in Communities. 相似文献

The determination of a cyclist’s lactate threshold (LT) has become an important test performed in sports science laboratories around the world. A limitation of such testing is that it is relatively expensive and invasive, requiring multiple blood samples. The purpose of the current study was to evaluate a commercially available, wearable lactate threshold sensor (WLT) that uses near infrared LED technology to measure gastrocnemius muscle oxygenation and predict LT. The WLT was compared to four traditional calculations of determining LT following an incremental exercise test. Ten male and five female recreational to elite cyclists (mean ± SD; age 24 ± 8, body mass 69.7 ± 7.3 kg, VO2max; 59.7 ± 9.9 ml kg?1 min?1) performed an incremental cycling test to exhaustion. Blood lactate samples were taken at the end of each 3-min stage during the test to determine lactate threshold using four traditional methods (TradLT, Dmax, mDmax, OBLA). Traditional methods were then compared against the WLT predicted value. The correlation between the WLT and TradLT, Dmax, mDmax and OBLA were all >r = 0.96. The highest level of agreement for the WLT was with the Dmax method (95 % limits of agreement: ±17 W, TEE = 8.6 W, 4.4 %). The 95 % level of agreement between the WLT and all other traditional methods was <±40 W (TEE <18 W, 8 %). In summary, the WLT is practical, easy to use and exhibits an acceptable level of agreement with four of the traditionally accepted methods of determining lactate threshold. 相似文献

The objective of this study is to evaluate the effect of interdisciplinary therapy in the parameters of the oxidative stress and the anti-inflammatory responses of obese adolescents. We selected 57 participants, who were randomly divided into 2 groups: interdisciplinary therapy group and a control group. After 6 months of intervention, 17 participants of the interdisciplinary therapy group and 8 of the control group returned for re-evaluation. The interdisciplinary therapy group participated in a treatment with 4 weekly sessions of exercise, a weekly group therapy session and a weekly nutritional education session. Blood parameters of oxidative stress and anti-inflammatory response were evaluated. The results demonstrated that there were significant increases in the interdisciplinary therapy group for superoxide dismutase activity (6.56 ± 3.22 to 11.40 ± 7.49) and ferric-reducing antioxidant potential concentration (532.91 ± 106.48 to 573.25 ± 112.57), although adiponectin levels did not reduce (40.9 ± 29.34 to 49.05 ± 41.22). A significant decrease in nitrite levels was also found (14.23 ± 8.48 to 11.45 ± 6.05). In the control group, significant reduction was found in adiponectin (31.56 ± 18.88 to 18.01 ± 11.66). This study suggests that interdisciplinary therapy for 6 months was effective in improving the anti-inflammatory responses and the antioxidant defences in obese adolescents. 相似文献

Differences in curriculum and teaching styles across disciplines in higher education courses are also evident in online courses. This study used two widely available sources of data, CMS tool usage logs and course evaluations, to analyze differences between online courses in disciplinary quadrants (hard-pure, hard-applied, soft-pure, soft-applied) at a large metropolitan university, over five years (2002 and 2007). For 2007, results revealed significant differences in tool usage between disciplines, particularly for assessment tools. Hard-pure courses used Tests and Pool tools more often than did soft-pure courses. The Document tool was used most extensively in applied courses. Data from course evaluations, for spring 2007 online courses, suggested that applied disciplines had a shorter learner–instructor transactional distance than did pure disciplines. Results suggest that over five years, e-learning in pure disciplines has become more commoditized, while e-learning in applied disciplines has become more diversified and more oriented to community practice. 相似文献
