ion (Vitalari and Dickson, 1983). These concepts from the psychology literature converge, and are extended to social interaction, in the notion of a "frame" (Goffman, 1974; Tannen, 1993). The framing concept operates at the intersection of a psychological-cognitive and a social-behavioral approach to human interaction (Ensink and Sauer, 2003). People behave according to "structures of expectati...
This chapter examines the role of leadership in overcoming social dilemmas within groups. First, based on prior theorising and research we present two alternative perspectives on leader endorsement in social dilemmas, an instrumental and relational perspective. Next, we systematically compare these perspectives in a series of experiments investigating leadership in social dilemmas created withi...
This paper examines learning in interdisciplinary action teams. Research on team effectiveness has focused primarily on single-discipline teams engaged in routine production tasks and, less often, on interdisciplinary teams engaged in discussion and management rather than action. The resulting models are of limited use for explaining differences in learning in interdisciplinary action teams. Me...
The present research examined social loafing in groups across different stages of group development. Individuals working in newly formed groups worked harder in the group setting than alone, although this difference was non-significant. However, individuals working in groups that were at the midpoint or end of their existence performed better when working by themselves. This latter finding is c...
Tumor necrosis factor (TNF)is a well validated therapeutic target for the treatment of rheumatoid arthritis. TNFis initially synthesized as a 26-kDa membrane-bound form (pro-TNF) that is cleaved by a Zn-metalloprotease named TNF-converting enzyme (TACE) to generate the 17-kDa, soluble, mature TNF. TACE inhibitors that prevent the secretion of soluble TNFmay be effective in treating rheumatoid a...
Members of eight single-sex groups each consisting of three proand three anti-capital punishment adherents discussed their views for 30 minutes, and afterwards individually rated ingroup and outgroup members on social in ̄uence ranking, prototypicality, and social attractiveness. From the intragroup hypothesis that speaking turns are a resource for in ̄uence (Ng & Bradac, 1993), we predicted and ...
The psychology of science typically lacks integration between cognitive and social variables. We present a new framework of team innovation in multidisciplinary science and engineering groups that ties factors from both literatures together. We focus on the effects of a particularly challenging social factor, knowledge diversity, which has a history of mixed effects on creativity, most likely b...
Pecan bacterial leaf scorch (PBLS) and the pathogen Xylella fastidiosa were identified in 20 pecan cultivars observed in Louisiana commercial orchards over a twoyear period. The disease occurred in the majority of orchards observed and was distributed throughout the pecan growing areas of the state. Leaf scorch was most prevalent in the Cape Fear cultivar. A few other cultivars sometimes exhibi...
How does memory affect surface-colour matching and is there any advantage with familiar scenes? A computercontrolled colour display system was used to present images of natural scenes and Mondrian patterns under two different daylights of correlated colour temperatures 25000 K and 6500 K, each lasting 1 s and separated by an interval lasting 0, 0.1, 0.2, 0.5, 1, 2, or 5 s, with a gradual transi...
The current paper provides insight into the learning strategies adopted by children working at Minimally Invasive Education (MIE) Learning Stations. Previous research has clearly indicated the attainment of basic computer literacy by groups of young children in the age groups of 7–14 years. This learning takes place due to the emergence and development of group social processes, an aspect cruci...
