Few studies have focused on how youth develop agency to organize and participate in online unstructured creative collaborations. This paper describes and analyzes how youth programmers organized collaborative groups in response to a programming “Collab Challenge” in the Scratch Online Community and in an accompanying workshop with high school students. The analyses focused on modalities of onli...

Pairs of eyewitnesses with a content-focused interaction style remember significantly more about witnessed incidents. We examined whether content-focused retrieval strategies can be taught. Seventy-five pairs of witnesses were interviewed thrice about an event. The first and third interview were conducted individually for all witnesses. The second interview was individual, collaborative without...

High-intensity focused ultrasound (HIFU) is a minimally invasive therapy modality in which ultrasound beams are concentrated at a focal region, producing a rise of temperature and selective ablation within the focal volume and leaving surrounding tissues intact. HIFU has been proposed for the safe ablation of both malignant and benign tissues and as an agent for drug delivery. Magnetic resonanc...

This communication reports a new theranostic system with a combination of capabilities to both enhance the contrast of photoacoustic (PA) imaging and control the release of a chemical or biological effector by high-intensity focused ultrasound (HIFU). The fabrication of this system simply involves filling the hollow interiors of gold nanocages with a phase-change material (PCM) such as 1-tetrad...

The advancement of professional nursing requires integration of theory, practice and research. One realistic mechanism to achieve this integration is collaborative nursing research. A collaborative experience between clinical nurse specialists and faculty researchers is described and evaluated. The collaborative research project focused on contraceptive nursing care and self-care conceptualized...

multiple sclerosis (ms) is a complex disease which is correlated with increasing inflammatory factors, demyelination and axonal loss. in this auto-immune disease, neuroinflammation is mediated by different types of t cells with macrophage/microglial activation and b cells involvement that interact in a collaborative manner. focal inflammation is the main cause for the onset of relapses and coul...

Memory research has primarily focused on how individuals form and maintain memories across time. However, less is known about how groups of people working together can create and maintain shared memories of the past. Recent studies have focused on understanding the processes behind the formation of such shared memories, but none has investigated the structure of shared memory. This study invest...

According to Dillenbourg et al. (1996), collaborative learning occurs when two or more people try to learn something together. This process consists of four successive stages, one of which concerns collaborative interactions. In this paper we present two studies that implemented two different ways of increasing the number of collaborative interactions. To increase the number of collaborative in...

The workshop “Web Infrastructure for Collaborative Applications” at WETICE’96 brought together 37 attendees from academia and industry. 14 selected papers were presented in the sessions named “Case Studies”, “Tools, Methods, Techniques”, “Application Requirements”, and “Collaborative Engineering”. A final discussion session and the collaborative effort of all participants to produce a summary o...

Interprofessional teamwork is widely advocated in health and social care policies. However, the theoretical literature is rarely employed to help understand the nature of collaborative relations in action or to critique normative discourses of teamworking. This paper draws upon Goffman's (1963) theory of impression management, modified by Sinclair (1997), to explore how professionals 'present' ...
