Methods for identifying students with learning disabilities continue to be an area of controversy. The present investigation examined the impact of implementing statewide guidelines for the identification of these students. Data were collected from multidisciplinary team reports on 718 students with learning disabilities who were referred and labeled during the 1983-84 school year (before implementation of statewide learning disability guidelines) and 790 students who were identified during 1987-88 (after implementation of the guidelines). The results of the study revealed that the statewide guidelines significantly changed the characteristics of students who were identified. After the implementation of the guidelines, students with much more severe academic problems were identified. These students were much more likely to have a severe discrepancy and be chronically failing in the regular classroom. However, even with explicit, widely accepted guidelines, approximately one third of all students identified in 1987-88 failed to meet the stated criteria for identification. The implications of these findings for professional practice and future research are discussed. 相似文献

Persistent school shootings have generated ongoing pressure to assess and enhance crisis communication effectiveness via strategies such as resilience-building and post-crisis restoration. A network perspective offers a robust, multilevel approach for examining complex information flows among community, campus, and individual actors affected by crises. Drawing on relational and structural embeddedness and Uncertainty Management Theory, we offer nine propositions that help explain structural and relational changes in a network over time. Although theoretically driven, these propositions are primarily functional, offering practical implications for safety officials and administrators trying to understand, prepare for, and respond to crises. Thus, we suggest measures and recommendations to improve information flow, uncertainty management, and resilience before, during, and after a crisis. 相似文献

The unforeseen trials of arts-based research may suppress creative and innovative explorations. Photovoice, a visual method of investigation employing participatory photography, presents a host of apprehensions. Yet, photovoice is both a valid and rich methodology that can greatly expand the reach and scope of applied communication research. In this essay, we – three applied communication researchers – discuss the complexities of photovoice, highlighting areas of consideration that interested researchers should contemplate before utilizing this methodology. Briefly exploring three of our research studies and their varying topics (i.e. long-term cancer survivors, domestic violence organizational advocacy, male body culture), we discuss three broad areas of difficulty in photovoice research: analysis, control, and exposure. Despite the unique obstacles that photovoice presents, we argue that it, along with other forms of arts-based research, are profitable and definitely worth the challenge. 相似文献

Rapid advances in technology have provided the potential to connect citizens to their surroundings in unprecedented ways. While many scholars examine different types of efficacy as a predictor of behavior (e.g., internal, external, and political), it is essential to examine how confident citizens feel in their ability to use the technology before understanding how they will use it politically. Research shows that perceived competence increases motivation, which is correlated with behavior. This study examined how traditional measures of efficacy and a new measure affect online political behaviors, concluding that technological efficacy is a reliable construct predicting online news use and expression. 相似文献

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect. 相似文献
