A Comparison of Responsive Interventions on Kindergarteners’ Early Reading Achievement

This study compared the effects of Tier 2 reading interventions that operated in response‐to‐intervention contexts. Kindergarten children (N = 90) who were identified as at risk for reading difficulties were stratified by school and randomly assigned to receive (a) Early Reading Intervention (ERI; Pearson/Scott Foresman, 2004) modified in response to student performance or (b) their schools’ typical supplemental reading intervention (regrouping and curriculum pacing adjustments). In both conditions, intervention was provided 30 minutes per day in small groups for approximately 100 sessions. Results indicated no statistically significant group differences on any outcome measures. Between‐group effect sizes revealed substantively important differences (Valentine & Cooper, 2003) favoring the ERI responsive condition on multiple measures with effect sizes ranging from .35 to .59. Overall, findings indicated that the majority of students in both Tier 2 intervention conditions performed above the 30th percentile on posttest measures of word reading measures.     

Rapid demand curves for behavioral economics

A method for determining the relationship between food consumption and the price of food (demand function) in behavioral economic experiments is described. Although previous methods have generally required as long as 40 days, the present method can generate a complete demand function within 7 days, and therefore may be more suitable for use in the evaluation of drugs, toxins, and physiological/anatomical interventions. Moreover, measures of circadian rhythmicity, post-reinforcement pause durations, and interresponse times can also be generated. Three experiments tested the stability of the method in a variety of procedural manipulations: repeated exposure to the procedure, increasing versus random daily food price, and size of daily changes in food price. The procedure generated demand functions that were similar to those that require more extended testing, and the demand functions were not generally affected by procedural manipulations. Body weight, which can also affect consumption, generally decreases with increases in the price of food; so this variable should be recorded and used as a covariate in analyzing demand functions. With the exception of circadian rhythmicity, the other measures were stable across procedural variations and showed expected changes as a function of food price: postreinforcement pause durations increased as price increased, but interresponse times did not.     

Curriculum Alignment with a Mission of Social Change in Higher Education

Institutions of higher education frequently acknowledge their role in contributing to the common good through their mission statements. The current literature suggests that in order to be effective mission statements must be clearly articulated and reflected in all the activities of the institution including its curriculum. Faculty members at Walden University developed a Curriculum Guide for Social Change that could serve as a tool for reviewing current course offerings and developing new courses to reflect its mission of “creating positive social change.” Those involved in piloting the Guide report on the process in this article. The general consensus is that it was time-consuming and frequently subjective; but the Guide gave substance to the institution’s mission, opening the way for its fuller implementation.     

Home advantage and the debate about competitive balance in professional sports leagues

A recurrent theme in sports economics is the extent to which overall league attendances will be raised by measures, such as revenue sharing, which aim to improve competitive balance. This debate has ignored the phenomenon of home advantage, which may, however, be important to the extent that, if all teams had equal talent, all matches may then be weighted heavily in favour of the home team. We present an analysis of the relationship between attendance and match-level uncertainty in the English Football League. A simulation from our model indicates that equality of playing talent would in fact lower aggregate attendance. This result is explained by the loss of prospectively the most uncertain games, where weak teams have home advantage over strong teams.
