TUDGE, JONATHAN R. H. Processes and Consequences of Peer Collaboration: A Vygotskian Analysis. CHILD DEVELOPMENT, 1992, 63, 1364-1379. A sample of 162 children aged from 5 to 9 was pretested to discover each child's "rule" for predicting the movement of a mathematical balance beam. Children then worked alone, with a partner who used the same rule, with a partner who was more competent, or with ...

OBJECTIVE To detect temporal case clustering in patients with pityriasis rosea in different geographic locations. DESIGN Regression analysis of dates on which 1379 patients were diagnosed as having pityriasis rosea in 3 different geographic locations. The control data consisted of dates of diagnosis of patients with psoriasis in the same settings. SETTING Dermatology clinics in Kuwait, Minn...

In the setting of partially ordered metric spaces, using the notion of compatible mappings, we establish the existence and uniqueness of coupled common fixed points involving a (φ ,ψ )-contractive condition for mixed g-monotone operators. Our results extend and generalize the well-known results of Berinde (Nonlinear Anal. TMA 74:7347-7355, 2011; Nonlinear Anal. TMA 75:3218-3228, 2012) and weake...

In this work, ultrafine SnO2 nanoparticles were prepared by a facile solvothermal route using SnCl4.5H2O as initial materials. Phase compositions and microstructures of as-prepared have been investigated X-ray diffraction (XRD), scanning electron microscopy (SEM), the particle size analyzer. It was found that obtained with good dispersibility exhibited pure rutile structural phase an average cr...

Multi-drug therapy (MDT) and Leprosy Elimination Campaigns (LEC) are the major strategies for eliminating leprosy. We report the results of a LEC conducted in 2006 in Qazvin. A total of 1987 individuals (1379 household contacts of 319 registered leprosy patients and 608 people from 3 endemic villages with a high prevalence of leprosy) were examined for detection of new cases of leprosy. All new...
