Comprehensive school-linked services: Implications for school psychologists

This article reviews the primary concepts underlying the current movement toward the provision of comprehensive school-linked services for children and families in low-income communities and the implications of this movement for school psychologists. The development of collaborative partnerships involving schools, public, and community-based agencies is an attempt to increase the availability and accessibility of needed services to children and families. The adoption of collaborative governance and a case management system is intended to offer an alternative to the proliferation of separate categorical programs and the associated lack of coordination among programs. The hope is to emphasize prevention and efficient early intervention. Collaborative efforts can provide an opportunity for role expansion among school psychologists. This possibility is discussed within a consultation model of service delivery that is consistent with the collaborative nature of school-linked services and with the preventive stance that orginated them. School psychologists are in a position to contribute to team consultation, case management, and needs assessment. Implications for training are drawn.     

Color characterization of roofing slates from the Iberian Peninsula for restoration purposes

Substitution of slate roofing tiles is a conventional operation during building restoration, since tiles are very difficult to restore or clean because of the high degree of alteration they suffer. Criteria for replacement of historical building stones must be based on geological, geotechnical and esthetic parameters, among which color is of great importance. In this sense, this paper constitutes a comprehensive and useful colorimetric study of roofing slates from the Iberian Peninsula, for the purposes of restoration. The color of 50 commercial varieties of roofing slate mined in quarries from the 12 mining districts in the Iberian Peninsula was analyzed with a spectrophotometer device, by considering the CIELAB color space. The results of the study were used to develop a protocol for characterizing the color of roofing slate and to define the color range of roofing slate from the Iberian Peninsula. In addition, the similarities and differences in the color and microstructure of the different commercial varieties of Iberian roofing slate were established and the limit of acceptability of replacement of one type of slate by another was determined. Parameter h_ab was found to be the most important CIELAB color coordinate as regards the formation of homogeneous color groups, and the specular component excluded (SCE) mode was most sensitive as regards detecting color differences between two samples.     

Acoustic sounding of the atmosphere

Measurement of vertical and horizontal wind velocity is of great importance in many contexts, such as investigation of air pollution, weather forecasting, and air-traffic control. In recent years continuously recording acoustic sounders have been developed which give reliable results at reasonable cost: some 200 are now in use in at least 15 countries.
