Comparison of two Actigraph models for assessing free-living physical activity in Indian adolescents     

Corder K  Brage S  Ramachandran A  Snehalatha C  Wareham N  Ekelund U 《Journal of sports sciences》2007,25(14):1607-1611

This aim of this study was to compare the new Actigraph (GT1M) with the widely used Model 7164. Seven days of free-living physical activity were measured simultaneously using both the Model 7164 and GT1M in 30 Indian adolescents (mean age 15.8 years, s = 0.6). The GT1M was on average 9% lower per epoch than model 7164, thus a correction factor of 0.91 is suggested for comparison between the two monitors. The differences between monitors increased in magnitude with intensity of activity (P < 0.001) but remained randomly distributed (r = 0.01, P = 0.96). No significant difference was observed between monitors for time spent in moderate (P = 0.31) and vigorous (P = 0.34) physical activity when using the same epoch length. The Model 7164 classified less time as sedentary (P < 0.001) and more time as light-intensity activity (P < 0.001) than the GT1M. In conclusion, data from the GT1M can be compared with historical data using average counts per minute with a correction factor, and the two models might be comparable for assessing time spent in moderate to vigorous physical activity in children when using the same epoch length.  相似文献   

Small Circles: Mobile Telephony and the Cultivation of the Private Sphere     

Rich Ling  Johannes Bjelland  Pål Roe Sundsøy  Scott W. Campbell 《The Information Society》2014,30(4):282-291

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius.  相似文献

Identity Challenges in Field Research: Three Stories     

Jan-Oddvar Sørnes  Ingunn Dahler Hybertsen  Larry Browning 《Journal of Applied Communication Research》2013,41(1):136-140

We tell of our struggles in completing ethnographic field research by showing the hurdles and difficult interactions we faced on our different projects. We interpret the obstacles as threats to our identities and show how we responded to them. Our conclusion shows how we preserved the independence of our interpretations while completing the data collection and interpretation.  相似文献

Justification beliefs and multiple-documents comprehension     

Ivar Bråten  Leila E. Ferguson  Helge I. Strømsø  Øistein Anmarkrud 《European Journal of Psychology of Education - EJPE》2013,28(3):879-902

Building on the multidimensional framework of epistemic cognition proposed by Greene et al. (Educational Psychologist 43:142–160, 2008), this study examined beliefs about justification of knowledge claims in science among 65 Norwegian 10th graders. The first research question asked whether beliefs in personal justification, justification by authority, and justification by multiple sources differed in strength among the participants. It was found that the students most strongly believed in justification by authority, followed by justification by multiple sources and personal justification. The second research question asked whether the three types of justification beliefs differentially and uniquely predicted the comprehension of multiple conflicting documents on a science issue. In a multiple regression analysis with multiple-documents comprehension indicated by essay performance as the dependent variable, both personal justification and justification by multiple sources emerged as unique predictors when topic knowledge was controlled for. Specifically, beliefs in personal opinion as a means of justifying knowledge claims in science was negatively related to multiple-documents comprehension, whereas beliefs in justification through corroboration across multiple sources of information were positively related to multiple-documents comprehension. This study provides new evidence about relationships between epistemic beliefs and new literacy competencies needed in an information society, such as integrating across multiple conflicting sources of information; relationships that may also have practical implications.  相似文献   

Legitimation,performativity and the tyranny of a ‘hijacked’ word     

Bjørn Stensaker 《教育政策杂志》2013,28(6):757-769

Accreditation is fast becoming the dominant method of evaluation used in the European Higher Education Area. This paper traces the political process supporting the introduction of this method in Europe and identifies different theoretical understandings and practices which shed light on how we can interpret the spread and role of accreditation in Europe, before discussing current trends in European and US accreditation, which could pave the way for a joint research agenda. In the conclusion, some possible implications of current developments are briefly presented.  相似文献   

Using action research to improve health and the work environment for 3500 municipal bus drivers     

Kjeld B. Poulsen  Søren H. Jensen  Elsa Bach  John F. Schostak 《Educational Action Research》2013,21(1):75-106

During the past five decades occupational researchers have documented that bus drivers’ health is worse than in almost any other profession. The authors suggest that the reason there has not been any successful attempt to change this situation is because the focus until now on removing statistically associated external risk factors has been too narrow. The article describes a project whose purpose was to improve the health and well‐being of 3500 Copenhagen bus drivers. At the end, more than 200 interventions were implemented. The authors adopted a new approach of combining epidemiological results and qualitative methodologies, creating a broader explanatory foundation for action, linked by repetitive processes of critical reflection, which was central to defining problems, explaining causes, developing sufficiently effective interventions and measuring effects. The project revealed the importance of several new and potentially preventable factors involving such issues as lifestyle, private stressors and inappropriate management. During the project period an evaluative framework was developed to explore and measure the complex effects of multiple interventions. Three years after the interventions were launched, follow‐ups revealed remarkable improvements such as reductions in stress and body pains, an increase in satisfaction, and improvements in management and the drivers’ cabin. This article is the story of a methodological journey, from classical epidemiology to an approach combining the strengths of survey (broad coverage), qualitative methods (in‐depth focus) followed by critical reflections and ending with action research.  相似文献
