The interactional work of configuring a mathematical object in a technology-enabled embodied learning environment

We present a detailed account of interactional mechanisms that support participation in STEM disciplinary practices as an adult and a child explore a technology-enabled embodied learning environment for mathematics. Drawing on ethnomethodological studies of technologyrich workplaces, we trace the process of transforming a vague reference into a mutually available mathematical object: a covariant variable. Our analysis reveals that this mathematical object is an interactional achievement, configured via a reciprocal process of instructing one another's attention. In particular, we demonstrate how participants' explicit responsiveness to indexical and multimodal resources achieves this object

Enskilment in the digital age: The interactional work of learning to debug

We present a detailed account of the interactional work between a programming instructor and a middle school student that leads to the resolution of an elusive error in the student’s code. By tracing the fine details of how this resolution came to be, we demonstrate how learning to debug in face-to-face interactions resembles a process of enskilment

Characterization of the vaginal microbiota of healthy Canadian women through the menstrual cycle

The intestinal immune system is severely affected by HIV and circulating microbial products from the intestinal tract that provide an ongoing source of systemic inflammation and concomitant viral replication. In addition, HIV-infected individuals can have a deregulated immune response that may hamper the anti-viral capacity of the host. Various probiotic organisms and prebiotic agents have been shown to enhance intestinal epithelial barrier functions, reduce inflammation, and support effective Th-1 responses. As these characteristics may benefit HIV patients, this review aims to provide a theoretical framework for the development of probiotic and prebiotic interventions specifically for this population. © 2010 Informa Healthcare USA, Inc
