This article discusses how social media research may benefit from social media companies making data available to researchers through their application programming interfaces (APIs). An API is a back-end interface through which third-party developers may connect new add-ons to an existing service. The API is also an interface for researchers to collect data off a given social media service for empirical analysis. Presenting a critical methodological discussion of the opportunities and challenges associated with quantitative and qualitative social media research based on APIs, this article highlights a number of general methodological issues to be dealt with when collecting and assessing data through APIs. The article further discusses the legal and ethical implications of empirical research using APIs for data collection. 相似文献

The present study highlights teacher stress related to student mental health promotion through the relationship between perceived competence, perceived responsibility and negative emotions. Data were derived from a mixed methods design, utilizing three focus group interviews (n = 15), followed by survey research (n = 771) amongst Norwegian K–12 teachers. The results suggest that teacher stress emerges chiefly from a mismatch between feeling responsible for and being able to help students with mental health problems. The data also point to the impact of time constraints in school context. Finally, the findings reveal significantly higher levels of perceived responsibility and negative emotions amongst female teachers, and significantly lower levels of perceived responsibility amongst teachers at higher grades. 相似文献

The article presents an analysis of 93 essays written in an upper secondary school context. The essays were collected in relation to a larger research project, which went on for 5 years in a Danish upper secondary school (2010–2015). The material represents both genders and the students are 15–17 years old. We deploy a theoretical framework taken from Norbert Elias’ notion on established-outsider relations [Elias, N., &; Scotson, J. L. (1994 [1965]). The established and the outsiders. London: SAGE] as well as his use of personal pronouns [Elias, N. (1978). What is sociology? London: Hutchinson, Elias, N. (2001). The society of individuals. New York: The Continuum International Publishing Group] in illustrating how people negotiate, position and navigate within figurational contexts [Elias, N. (1994 [1939]). The civilizing proces. Oxford: Blackwell.]. We do this in an effort to interpret how young people negotiate ‘we-I-relations’ when it comes to their sporting identity. Elias’ processual framework provides a tool for a much needed analysis of how young people continually orientate and develop their sense of selves. The web of human interdependencies and processes of change are key words when it comes to understanding the social practices and doings of the students’ constructions of self-steering. What social scientists may see as laziness and drop-outs of sports [Seippel, Ø. (2016). Prek, vekker og kjedelig? Trening og mening blant ungdom: 1985–2013. In Ø. Seippel, M. K. Sisjord, &; Å Strandbu (Eds.), Ungdom og Idrett. Oslo: Cappelen Damm Akademisk] can in the essays of students be analysed as a struggle for group connectedness and social inclusion in the classroom. The results of our research show that identity is a multiple concept and an ongoing process of emotional work [Elias, N. (1987). On human beings and their emotions: A process-sociological essay. Theory Culture Society, 4, 339–361], but also a power balance of playing and presenting what is imagined as the right performance as not being shamed as outcasts. 相似文献

Actovegin, a deproteinized haemodialysate of calf blood, is suggested to have ergogenic properties, but this potential effect has never been investigated in human skeletal muscle. To investigate this purported ergogenic effect, we measured the mitochondrial respiratory capacity in permeabilized human skeletal muscle fibres acutely exposed to Actovegin in a low and in a high dose. We found that Actovegin, in the presence of complex I-linked substrates increased the oxidative phosphorylation (OXPHOS) capacity significantly in a concentration-dependent manner (19?±?3, 31?±?4 and 45?±?4?pmol/mg/s). Maximal OXPHOS capacity with complex I and II-linked substrate was increased when the fibres were exposed to the high dose of Actovegin (62?±?6 and 77?±?6?pmol/mg/s) (p?Vmax and Km were also increased in a concentration-dependent manner after Actovegin exposure (70?±?6, 79?±?6 and 88?±?7?pmol/mg/s; 13?±?2, 25?±?3 and 37?±?4?pmol/mg/s; 0.08?±?0.02, 0.21?±?0.03 and 0.36?±?0.03?mM, respectively) (p?相似文献

Studies in the history of science and education have documented that the reception and understanding of evolutionary theory is highly contingent on local factors such as school systems, cultural traditions, religious beliefs, and language. This has important implications for teaching evolution in primary and secondary schools. No universal strategy can be applied in overcoming the barriers of learning that exist and that are part of the practical and daily life in classrooms all over the world. In light of this, a huge challenge is to make high standard teaching materials fit to specific target audiences readily available. As more and more schools require teachers to use low cost or free web-based materials, in the research community we need to take seriously how to facilitate that demand in communication strategies on evolution. This article addresses this challenge by presenting the learning experience of making a digital archive of Danish Darwin editions that marked the beginnings of a series of public engagement and teaching initiatives including, among other things, comprehensive new websites, exhibits, lecture series, television documentaries, and a computer game. 相似文献
