CEC’s Standards for Classifying the Evidence Base of Practices in Special Education

Abstract: As an initial step toward improving the outcomes of learners with disabilities, special educators have formulated guidelines for identifying evidence-based practices. We describe the Council of Exceptional Children’s new set of standards for identifying evidence-based practices in special education and how they (a) were systematically vetted by expert special education researchers through a Delphi study, (b) demonstrated adequate inter-rater reliability in a pilot study, (c) delineate specific criteria in many areas and provide flexibility to tailor other criteria, (d) provide an integrated set of standards for classifying the evidence base of practices based on findings from both group comparison and single-subject studies, and (e) can be applied by independent special education researchers. We conclude by noting limitations to the standards, briefly comparing these new standards with other evidence-based practice standards, and providing recommendations for future research and for refining the standards.

Service Climate Effects on Customer Attitudes: An Examination of Boundary Conditions

Abstract: Our aim in this study was to extend theory on service climate by examining two boundary conditions for the effects of service climate on customer attitudes. We hypothesized that (1) the more proxim...

Economic Production Lot Size Model with Variable Production Rate and Imperfect Quality

Abstract: The classical economic production lot size (EPL) model assumes a constant production rate that is predetermined and inflexible, and perfect quality. Recent models have removed the assumption of perfect quality while maintaining the inflexible production rate assumption. Production rates in many cases, such as orders filled by a machine, can be changed. Moreover, unit production cost and process quality depend on the production rate. In this paper, we extend the EPL model to cases where the production rate is a decision variable. Unit production cost becomes a function of the production rate. Also, the quality of the production process deteriorates with increased production rate. We solve the proposed model for special cost and quality functions and illustrate the results with a numerical example. The results show that, for cases where increases in the production rate lead to a significant deterioration in quality, the optimal production rate may be smaller than the rate that minimizes unit production cost. For cases where quality is largely independent of the production rate, the optimal production rate may be larger than the rate that minimizes unit production cost.
