Multicast research has so far been focused on routing and network-level group management. Conditions on the composition of multicast groups have however been kept simple, with little efforts to specify requirements in terms of membership, member roles and group organization. Integrity conditions on multicast groups have been largely neglected despite the fact that it is often desirable to expre...

Recent research in group cognition points towards the existence of collective cognitive competencies that transcend individual group members' cognitive competencies. Since rationality is a key cognitive competence for group decision making, and group cognition emerges from the coordination of individual cognition during social interactions, this study tests the extent to which collaborative and...

This paper offers an empirical analysis of the relationship between income sharing rules and heterogeneity in medical group practices. The economies to group formation associated with risksharing, mutual monitoring, and internal referral are served by sharing at least a portion of group income equally. Sharing group income equally is problematic, however, when group members differ in their cont...

An iconic member of the Ediacara Biota, Dickinsonia Sprigg is one few such taxa with multiple species. Here we use Gaussian finite mixture models to assess validity species distinctions for this genus. Our results indicate that five described from Member, South Australia are better classified as two based on approaches. Two different methods dimension reduction both provide strong support group...

BACKGROUND The World Health Organization recommends direct observation of treatment (DOT) to support patients with tuberculosis (TB) and to ensure treatment completion. As per national programme guidelines in India, a DOT provider can be anyone who is acceptable and accessible to the patient and accountable to the health system, except a family member. This poses challenges among children with ...

OBJECTIVES To compare learning outcomes and perceptions of facilitator behaviours and small-group process in problem-based learning (PBL) groups led by students and those led by faculty. DESIGN A prospective, Latin-square cross-over design was employed. Second-year medical students participated in 11 PBL cases over the course of the academic year. For each case, half the student groups were l...

a comparison between design codes i.e. aci and aisc-lrfd in evaluation of flexural strength of concrete filled steel tubular columns (cfts) is examined. for this purpose an analytical study on the response of cfts under axial-flexural loading is carried using three-dimensional finite elements with elasto-plastic model for concrete with cracking and crushing capability and elastoplastic kinemati...

leadership is important for nurturing employee creativity. although how leaders can influence employee creativity is somehow unclear, previous studies show that leadership can enhance employees’ willingness to share knowledge. this study examines how leader-member exchange (lmx) affects employees’ creative work involvement through knowledge sharing. data (n=385) was collected utilizing a questi...

Much of human learning happens in the social world. A person's social identity-the groups to which they belong, the people with whom they identify-is a powerful cue that can affect our goal-directed behaviors, often implicitly. In the present experiment, we explored the underlying neural mechanisms driving these processes, testing hypotheses derived from social identity theory. In a within-subj...
