Experimentation and Innovation in U.S. Publishing Today: Findings from the Book Industry Study Group

In February 2008 the Book Industry Study Group (BISG) conducted a survey of U.S. publishers to determine the extent of technology-driven innovation and experimentation. The survey findings were published alongside a set of 10 case studies in May 2008 as “From experimentation to innovation in the digital age—case studies from the North American Book Industry 2008”. This article, written by Michael Healy, Executive Director of the BISG, summarizes the circumstances that led to the survey and shares the key findings.     

e-Trust and reputation

Trust online can be a hazardous affair; many are trustworthy, but some people use the anonymity of the web to behave very badly indeed. So how can we improve the quality of evidence for trustworthiness provided online? I focus on one of the devices we use to secure others’ trustworthiness: tracking past conduct through online reputation systems. Yet existing reputation systems face problems. I analyse these, and in the light of this develop some principles for system design, towards overcoming these challenges. In providing better evidence for trustworthiness online, so we can also encourage people actually to be trustworthy more often, which is an ethically welcome outcome.     

Using Variables in School Mathematics: Do School Mathematics Curricula Provide Support for Teachers?

This study employed content analysis to examine 3 popular middle-grades mathematics curricula in the USA on the support they provide for teachers to implement concepts associated with variables in school mathematics. The results indicate that each of the 3 curricula provides some type of support for teachers, but in a varied amount and quality. More specifically, whereas the University of Chicago School Mathematics Project (UCSMP) curriculum provides support for teachers on several aspects of using variables in school mathematics, the support found in the Connected Mathematics 2 and the Math Connects curricula focused mainly on one conception of variables—namely, the use of variables as quantity that varies in the Connected Mathematics 2 curriculum and the use of variables as specific unknowns in the Math Connects curriculum. Overall, the UCSMP curriculum provides the most support for teachers, followed by the Connected Mathematics 2 curriculum, with the Math Connects curriculum recording the least support for teachers to enact variable concepts. It is worth pointing out that, although the 3 curricula collectively provide guidance for teachers to implement variable ideas within meaningful real-world contexts, the supports identified in the respective curriculum were not sufficient in addressing all of the areas that are essential for teaching the many concepts associated with variables in school mathematics effectively. Recommendations for curriculum developers and for international researchers with interest in the roles of variables in school mathematics are provided.     

Voluntarily exiled? Korean state’s cultural politics of young adults’ social belonging and Korean students’ exile to a US community college

This study examines the complicated interlink between the Korean state’s neoliberal identity politics and working- and lower middle-class Korean students’ study abroad as a form of voluntarily exile. Drawing on a critical discourse analysis and a 14-month ethnographic study, this study discusses how these students’ decisions to study abroad are inextricably intertwined with the authoritarian Korean state’s neoliberal political-economic strategies of pushing out seemingly less-profitable citizens (namely, students and graduates of low-ranking 4-year institutions). This study also examines students’ strategies for simultaneously resisting and conforming to this neoliberal ethos. For working-class and lower middle-class Korean community college students, study abroad means a deviation from the normal educational and life trajectories in Korea while, at the same time, their education in the USA opens a pathway for reentering the Korean neoliberal system as more profitable citizens. Their being recognized as members of a profitable workforce indicates their achievement of neoliberal normalcy.
