Given the rise in obesity and the positive exercise effects in curbing obesity levels, exercise promoters are expected to use technological applications—social media and fitness applications—in their exercise motivational programs. The purpose of this article is to critique the use of social media and fitness apps as both ineffective and potentially harmful. An alternative approach is proposed where phronesis (practical wisdom) in exercise participation can be achieved via physical and cognitive mastery of the action for its own sake (real techne-art, embodiment). Emphasizing exercise outcomes (e.g., energy expenditure) captured by external devices distracts from embodied and phronetic action. Drawing on the philosophies of phronesis, techne, and embodiment, exercise promoters should emphasize embodied exercise experiences via mastery of action, social interactions, and connectedness to nature. They should target real action in real communities, and not emotionless and meaningless online forums about how to become the ultimate virtual fitness buff.  相似文献

The news media plays a vital role in providing child protection information and resources, shaping the public’s understanding and perceptions of child maltreatment, and exposing system failures and setting policy agendas. To date, little is known about how child maltreatment is portrayed in the media in societies where these issues remain largely hidden and under-recognized. The purpose of the present study was to systematically examine newspaper coverage on child abuse and neglect in Hong Kong in order to assess how child maltreatment is currently presented and framed within public discourse.A total of 579 newspaper reports relevant to child maltreatment from four local newspapers in 2016 were reviewed. Similar to prior findings, cases involving sexual abuse received disproportionately more attention compared with other maltreatment types. The vast majority of news reports focused on specific cases or events, and seldom discussed child maltreatment as a broader social issue. Differences in reporting style and media framing were also compared by newspaper credibility, and for free versus paid newspapers.As a mass communication tool, more guidelines are needed to formulate public messages about child maltreatment that can improve individual, community, and structural capacities to prevent, identify, and respond to children who are victimized by abuse and neglect. This is especially important in jurisdictions where no mandatory reporting framework exists to help identify vulnerable children, and where the majority of child maltreatment is brought to the attention of authorities by families and those living within the child’s community.  相似文献

The media analysis is situated in the larger body of studies that explore the varied reasons why different policy actors advocate for international large-scale student assessments (ILSAs) and adds to the research on the fast advance of the global education industry. The analysis of The Economist, Financial Times, and Wall Street Journal covers publications on ‘PISA’, ‘TIMSS’, and related search items over the period 1996–2016. The three media outlets vary in terms of ILSA reporting. The Economist and Financial Times tend to focus on PISA, whereas the Wall Street Journal pays greater attention to TIMSS than PISA. The content analysis of 59 articles yields interesting results about how the business-oriented readership of the three media outlets frames public education and why it sees education as a profitable business opportunity. The three most common narratives, reflecting the business logic, are the following: (i) public education is in crisis; (ii) there is no correlation between spending and education outcome; and (iii) school accountability, teacher performance, and decentralisation represent the most effective policies to improve the quality of education. Drawing on these three common narratives, the financial media outlets present a particular vision of how to improve education; a vision in which the private sector is supposed to play a major role.  相似文献

Video production offers a way for students to learn content-area knowledge while simultaneously developing technology skills deemed important in contemporary society. Yet, the research has not been examined in a systematic way to reveal how these types of projects are oriented to align to instructional goals or how learning is investigated when they are implemented as part of content-area pedagogy. A scoping study was conducted to review the research literature on implementation of student video production in content-area classrooms. A total of 61 studies published from 2006 through 2017 were selected and analyzed through a systematic process. Findings suggest that video production projects were conducted to meet information, performance, composition, literacy, or creativity learning goals in content-area classrooms. Strategies used to investigate student learning included evaluation of learner perceptions, analysis of the process of creating video, assessment of the final video project, or a combination of these approaches.  相似文献

This article aims to contribute new knowledge about the media literacies children assemble as they play the digital game Minecraft which it describes as a children's digital making platform. The article argues media literacy's tendency to use socio-cultural and humanist accounts of media participation limit its ability to fully explain digital making practices. Socio-material and performative literacy theories are used to introduce a framework for exploring digital media literacies across four nodes: digital materials, media production, conceptual understanding and media analysis [Dezuanni, M. 2015.“The Building Blocks of Digital Media Literacy: Socio-material Participation and the Production of Media Knowledge.”Journal of Curriculum Studies 47 (3): 416–419]. The article's second half outlines how the author uses digital ethnography in his home to understand children's Minecraft digital making and the article's theoretical claims are explored using empirical data. The conclusion considers the ramifications of digital making for media literacy research and practice.  相似文献

Effective teamwork, knowledge coordination, and knowledge creation are recognized as essential sources of team effectiveness and creativity in modern organizations. Nowadays, social media is significantly modifying the patterns in the use of technology to support knowledge management practices in teams. At the same time, the literature shows that transactive memory system (TMS), which refers to how team members share their distributed knowledge and expertise, is an important factor affecting team performance. However, minimal effort has been made to elaborate on the precise role of social media in supporting TMS for enhancing absorptive capacity (ACAP) and knowledge creation capability (KCC) of the team, which in turn might influence team creative performance (TCP). Therefore, to address this gap in the literature, a theoretical model is developed and validated. Survey data collected from 334 members of 68 knowledge work teams indicated that social media use at work has a positive relationship with TMS and both social media use at work and TMS are positively related to ACAP and KCC of the team. Results further indicated that ACAP positively influenced KCC, and both have a direct relationship with TCP. This study shows that careful investment in social media by an organization can enhance meta-knowledge of “who knows what” within teams. Finally, exploring external knowledge alone is not enough. Instead, organizations must ensure external knowledge is utilized to create new knowledge to improve TCP.  相似文献

The literature on trolling has viewed trolling as discrete instances of transgression undertaken by antagonistic individuals. We identify three main issues with current theorizations: diffuse definitions of “trolling,” blurred boundaries between trolling and other online anti-social behaviors, and the context dependency of trolling. To address these unresolved issues, we adopt a practice-based theoretical approach. Informed by this approach, we analyze trolling behaviors not as products of individuals' attitudes, values, and decisions, but rather as behaviors embedded within and occurring as part of social practices. Specifically, we conduct a practice-based theoretical analysis in a multi-site exploratory study involving online archival research and in-depth interviews with online community members. Based on this analysis, we propose that trolling be conceived as a constellation of three social practices: learning, assimilating, and transgressing. Also, we find that practices of trolling transgression can have a dual pro-social and anti-social impact in online communities.  相似文献

In the 1990s the aphorism “information wants to be free” reigned supreme, limiting our thinking in consequential ways. In actuality this aphorism was a fragment of a much more nuanced statement by Steward Brand, who also talked about “information wants to be expensive.” It seemed for quite a while that there was no resolution to the contradiction: information as both free and expensive. Eventually Web 2.0 resolved this contradiction by providing an architecture where information could be both free and expensive. Web 2.0 was not a product of technological advances: social media, wikis, big data platforms, and so forth. It was borne out of the understanding that free information on media platforms could yield profitable data on users. This article lays bare the discursive moves through which this understanding came about.  相似文献
