Basically this is a Rowbotham type connection piece with elongated stem in which the perforations have been made. A rotating inner drum with matching perforations allows partial or complete occlusion of the holes when necessary. The internal diameter of the stem is the same as in a standard Rowbotham piece. I have used the connection in clinical practice for over twelve months and have found it...

Previous studies of the connection between school enrollment size and student achievement use cross-sectional econometric models and thus do not account for unobserved heterogeneity across schools. To address this concern, I utilize school-level panel data, and generate first-differences estimates of the effect of school size on achievement. Moreover, to account for the possibility that trends ...

The current longitudinal study examines the extent to which school connectedness (i.e., students' perceptions of school support and the number of adults with whom they have a positive relationship) is associated with academic outcomes across sixth grade for students from high poverty neighborhoods.

The student resilience survey (SRS) covers a range of external supports and internal characteristics which can potentially be viewed as protective factors and can be crucial in exploring the mechanisms between...

The potential endogeneity of grade repetition is corrected for using the differences among teacher attitude to repetition as an instrument for grade repetition. The results sh...

With the implementation of the federal "No Child Left Behind" Education Act, schools in America are under increased pressure to demonstrate academic success through higher test scores. Academic leaders are increasingly recognizing that the issues that students confront are not unique to the school setting but are issues of the larger community. Stronger links need to be forged between those wor...

Few studies have presented the use of hypnosis in the treatment of school refusal. These studies haven't approached the problem of self-hypnosis during the stressful morning hours. This paper introduces a therapeutic approach, which utilizes known hypnotic techniques, but rehearses them via the telephone, while the patient is at his/her house or on the way to school and the therapist is at the ...
