Time for break: Understanding information workers' sedentary behavior through a break prompting system

Extended periods of uninterrupted sedentary behavior are detrimental to long-term health. While prolonged sitting is prevalent among information workers, it is difficult for them to break prolonged sedentary behavior due to the nature of their work. This work aims to understand information workers' intentions & practices around standing or moving breaks. We developed Time for Break, a break prompting system that enables people to set their desired work duration and prompts them to stand up or move. We conducted an exploratory field study (N = 25) with Time for Break to collect participants' work & break intentions and behaviors for three weeks, followed by semistructured interviews. We examined rich contexts affecting participants' receptiveness to standing or moving breaks, and identified how their habit strength and self-regulation are related to their break-taking intentions & practices. We discuss design implications for interventions to break up periods of prolonged sedentary behavior in workplaces. © 2018 Association for Computing Machinery

Denial of Choice: Group Level Disclosure of Private Information

Part 2: CommunicationsInternational audienceWhile online social networks (OSNs) allow users to selectively share content as well as limit access to information within users’ own virtual spaces, unfortunately there is little or no control on other-generated content. The full study explores an interdependent privacy regarding other-generated disclosures on OSNs from insiders’ perspectives (the ‘discloser’ and the ‘disclosed’), based upon their lived experiences. An online survey was used to recruit suitable participants who meet the purposive sampling criteria. This paper presents some preliminary findings from a current study, based on an online survey. The online survey result reveals a likelihood of activities associated with other-generated disclosure. This study makes a contribution to the scant literature on OSN interdependent privacy as well as draws attention to tackle these privacy issues in order to discover effective detection mechanisms towards practical solutions in the future

Using Cultural Representations in Video Games to Confront Stereotypes and Misconceptions About Brazil: \u3cem\u3eFavelas, Futebol,\u3c/em\u3e and \u3cem\u3eBrasilidade\u3c/em\u3e

Despite being the fifth largest country on earth, Brazil’s representation in video games, from stories to settings to characters, has been limited. Brazilian settings in video games include the exoticized Amazon or the famous shantytowns, the favelas. Portrayals of the favelas turn them into shooting galleries, built on stereotypes of lawlessness and militarism. Brazilian video game characters are built on signifiers of Brasilidade, or “Brazilian-ness,” including the hypersexualization of women and futebol (i.e., soccer) fanatic men. Characters originating from the Amazon have been portrayed as exotic literal monsters, electric green men, and fish people. This chapter explores these stereotypes and misrepresentations, as well as recent positive developments in Brazilian video game development that confront these tropes, presenting a richer, more diverse view of Brasilidade, or what it means to be Brazilian. Recommendations for how to teach around and with these representations will be discussed as a way to challenge stereotypes and move toward more critical gaming practices that unpack the role global cultural representation in gaming plays in power and social justice in online encounters, and ultimately, with the Other

Challenges to international stem cell clinical trials in countries with diverging regulations

This chapter addresses challenges to the organization and conduct of international stem cell clinical trials in a context of regulatory pluralism. Multi-country clinical trial collaborations in stem cell medicine have the potential to speed up clinical developments and to widen access to new treatments among patients. However, the regulatory procedures through which the safety and efficacy of stem cell-based treatments are determined vary widely across countries. Internationally harmonized governance frameworks are not yet in place. In this chapter we show that this high level of regulatory variation and the absence of internationally binding standards for clinical stem cell research present important challenges to multi-country clinical trial collaborations. Four types of challenges will be highlighted. First is the need to inquire into and interact with regulatory procedures and law in multiple countries. Second, the interaction with medical authorities in multiple countries is resulting in a high level of organizational complexity. Third consists of delays, increased costs, and uncertainties that result from nonexistent, unclear, or still emerging regulatory arrangements in different countries. Fourth is that the high level of regulatory variation across countries necessitates far-reaching forms of scientific self-governance, training, and procedural adjustments in participating clinical trial sites. To illustrate this point, the chapter presents a case study of project-internal self-governance and capacity building in the context of a clinical trial infrastructure that is active across the contexts of China, Hong Kong, and the USA. The chapter concludes with a call for the creation of an international support structure that systematically addresses these problems. Five measures that may help to reduce existing difficulties will be introduced
