Improving sedentary measurement is critical to understanding sedentary-health associations in youth. This study assessed agreement between the thigh-worn activPAL and commonly used hip-worn ActiGraph accelerometer methods for assessing sedentary patterns in children. Both devices were worn by 8–12-year-olds (N = 195) for 4.6 ± 1.9 days. Two ActiGraph cut-points were applied to two epoch durations: ≤25 counts (c)/15 s, ≤75c/15s, ≤100c/60s, and ≤300c/60s. Bias, mean absolute deviation (MAD), and intraclass correlation coefficients (ICCs) tested agreement between devices for total sedentary time and 11 sedentary pattern variables (usual bout duration, sedentary time accumulated in various bout durations, breaks/day, break rate, and alpha). For most sedentary pattern variables, ActiGraph 25c/15s, 75c/15s, and 100c/60s had poor ICCs, with bias and MAD >20%. ActiGraph 300c/60s had a better agreement than the other cut-points, but all ICCs were <0.587. ActiGraph underestimated sedentary time in longer bouts and usual bout duration, and overestimated sedentary time in shorter bouts, breaks/day, and alpha. For total sedentary time, ActiGraph 25c/15s, 300c/60s, and 75c/15s had good/fair ICCs, with bias and MAD <20%. Sedentary patterns derived from two commonly used ActiGraph cut-points did not appear to reflect postural changes. These differences between measurement devices should be considered when interpreting findings from sedentary pattern studies.  相似文献   

Carrying out research across the arts and humanities and social sciences: developing the methodology for Dementia and Imagination     

Andrew Newman  Michael Baber  Dave O’Brien  Anna Goulding  Catrin Hedd Jones  Teri Howson 《Cultural Trends》2016,25(4):218-232

This paper analyses how the methodological approach for a major Arts and Humanities Research Council and Economic and Social Research Council-funded project entitled Dementia and Imagination ¹1. http://dementiaandimagination.org.uk/View all notes was formulated. This multidisciplinary project brings together the arts and humanities with the social sciences with their different epistemological philosophies and subsequent understandings of research methods. The main objective was to determine how visual arts activities may change, sustain and catalyse community cultures, beliefs, attitudes and behaviours to create dementia-friendly communities. This project involves 6 different UK universities, 14 researchers, 10 formal partners, 7 project artists, 3 research artists and a large number of civil society organisations. The analysis presents a series of themes that have been identified as influencing the approach taken to develop methods which aimed to speak to different audiences in the social sciences, arts and humanities, policy/practice and public domains. It is concluded that a research project of this type needs to embrace a wide variety of epistemological positions if it is to successfully achieve its objectives. This paper contributes to knowledge about how the methodology of large-scale multidisciplinary projects may be constructed which will be of value to those building research consortia across different universities and between universities and community partners.  相似文献   

Networks of value in electronic music: SoundCloud,London, and the importance of place     

Daniel Allington  Byron Dueck  Anna Jordanous 《Cultural Trends》2015,24(3):211-222

While recent debate has often focused on a reified “cultural value” (whether opposed to or aligned with monetary value), this article treats “value” as a verb and investigates the acts of valuing in which people engage. Through ethnographic research in London's electronic music scene and social network analysis of the SoundCloud audio sharing website (which is dominated by electronic dance music and, to a lesser extent, hip hop), it uncovers substantial patterns of geographical inequality. London is found at the very centre of a network of valuing relationships, in which New York and Los Angeles occupy the next most privileged locations, followed by Berlin, Paris, and Chicago. Cities outside Western Europe and the Anglophone world tend to occupy peripheral positions in the network. This finding suggests that location plays a major role in the circulation of value, even when we might expect that role to have been curtailed by an ostensibly “placeless” medium for the distribution and valuing of music. While there are reasons for the metropolitan emplacedness of dance music – given the importance of the relationship between production, consumption, and live DJing – the privileging of particular cities also mirrors patterns of inequality in the wider cultural economy. That London should appear so supremely privileged reflects both the exporting strength of British creative industries and the imbalanced nature of the UK's cultural economy.  相似文献   

Sex differences in injury rates in team-sport athletes: A systematic review and meta-regression analysis

Background:Team-sport players have a particularly high injury risk.Although female sex is considered a risk factor,it is still unknown whether female and male team-sport players,in fact,differ in their injury rates.We aimed to compare injury rates between female and male players by systematically reviewing and meta-analyzing injury surveillance studies of both sexes in order to evaluate sex-specific differences in team-sport injuries.Methods:Studies that prospectively collected injury data for high-level female and male players(age≥16 years)in basketball,field hockey,football(soccer),handball,rugby(union and sevens),and volleyball were included.Two reviewers(AZ and ALR)independently assessed study quality and extracted data for overall,match,training,and severe injuries(>28 days’time loss)as well as data regarding injury locations and types.Incidence rate ratios(IRRs)were pooled in a meta-analysis,and meta-regression analysis was performed when 10 or more studies were available.Results:Of 20 studies,9 studies reported injury data from football,3 studies from rugby,3 studies from handball,1 study from basketball,1 study from field hockey,2 studies from volleyball,and 1 study from basketball and field hockey.For overall injuries,the pooled IRR=0.86(95%confidence interval(95%CI):0.76-0.98)indicated significantly more injuries in male than in female players.For injury location,the pooled IRR showed higher injury rates in male athletes than in female athletes for upper extremity,hip/groin,thigh,ande foot injuries.Female players had a significantly higher rate of anterior cruciate ligament injuries(IRR=2.15,95%CI:1.27-3.62)than male players.No significant sex-specific differences in IRR were found for match,training,severe injuries,concussions,or ankle sprains.Conclusion:Our meta-analysis provides evidence for sex-specific differences in the injury rates in team sports.Further epidemiological studies including both sexes in sports other than football are needed in order to strengthen the evidence.  相似文献

Coining Offences in England and Wales,c. 1675–1750: The Practical and the Personal     

Anna Field 《Cultural and Social History》2018,15(2):177-196

This article argues for a departure from previous conceptual frameworks that have categorised early modern coining offences as ‘social crimes’ similar to poaching, smuggling and riot. It seeks instead to complement the work undertaken by Malcolm Gaskill, Carl Wennerlind and Nicholas Tosney by contributing to their holistic interpretations of the offences from a variety of legal, economic and cultural perspectives. Through an analysis of elite views, cheap print, and the textual content of Mint depositions and trial summaries, this article argues that the ways in which contemporaries understood the practicalities of clipping, counterfeiting, and uttering as illicit depended largely on individual factors. These included the morality of work and labour, and specific roles and relationships of coiners.  相似文献

Combining the travel cost and contingent behavior methods to value cultural heritage sites: Evidence from Armenia     

Anna Alberini  Alberto Longo 《Journal of Cultural Economics》2006,30(4):287-304

This paper combines the travel cost method (TCM) with contingent behavior questions to estimate domestic visitors’ use values for cultural heritage sites in Armenia, a transition economy in which conservation of cultural monuments is hampered by limited resources. Respondents intercepted at four cultural monuments provided information on their visitation patterns, experience at the site, perception of the state of conservation of the monuments, and rating of the quality of the services and infrastructure. We combine actual trips with stated trips under hypothetical programs that would enhance the conservation of the monuments and improve one of (i) the cultural experience at the site, (ii) the quality of the infrastructure, or (iii) the quality of the services, and use the combined actual and stated trips to fit a panel data model. Our study is one of the few applications of the TCM to value cultural heritage sites. Our investigation shows that (i) significant use values are associated with the four study monuments, and (ii) conservation programs and initiatives that improve the cultural experience, or simply make it easier for the respondent to reach and spend time at the monument, are valued by domestic visitors and would encourage higher visitation rates. Actual and intended trips reported by the respondents exhibit good construct validity, in the sense that they are well predicted by price, location, hypothetical scenario and other individual characteristics of the respondents.

Reducing the grade disparities between American Indians and Euro-American students in introduction to psychology through small-group,peer-mentored,supplemental instruction     

Morris Alan Okun  Anna Berlin  Jeanne Hanrahan  James Lewis  Kathryn Johnson 《教育心理学》2015,35(2):176-191

Supplemental instruction (SI) is a small-group, peer-mentored programme which is compatible with the learning preferences of American Indian students. We tested the hypothesis that SI is a compensatory strategy that reduces the differences in the grades earned in introduction to psychology by Euro-American and American Indian students. The sample consisted of 129 American Indian students and 4588 Euro-American students enrolled in introduction to psychology at a US university. As hypothesised, a multi-level model yielded a significant (p < .01) interaction between SI and ethnicity on course grade. Whereas for non-SI users, the gap between Euro-American and American Indian students was .71 grade points, for SI users, it was only .15 grade points. Strategies should be devised for increasing SI visits by students enrolled in introduction to psychology, particularly those who belong to American Indian tribes.  相似文献
