Stock market response to changes in movies’ opening dates

How does the market react to news regarding large uncertain projects? We analyze stock market reactions to information about changes in opening dates of movies, and present two main findings. First, we find systematic negative stock price responses to the scheduling changes we consider, suggesting that any changes are interpreted as bad news by the market. Second, we find that the market reaction is greater for movies with higher production costs, but is unrelated to subsequent box office revenues. This may point to a limited ability of the market to predict the box office performance of a movie, and to increased sensitivity of the market to cost effects, which are easier to forecast.     

Child care quality matters: how conclusions may vary with context

Three studies examined associations between early child care and child outcomes among families different from those in the National Institute of Child Health and Human Development (NICHD) Early Child Care Research Network study. Results suggest that quality is an important influence on children's development and may be an important moderator of the amount of time in care. Thus, the generalizability of the NICHD findings may hinge on the context in which those results were obtained. These studies, conducted in three national contexts, with different regulatory climates, ranges of child care quality, and a diversity of family characteristics, suggest a need for more complete estimates of how both quality and quantity of child care may influence a range of young children's developmental outcomes.     

The effect of an historical perspective on prospective teachers’ beliefs in learning mathematics

Many learners hold traditional beliefs about mathematics that can hamper their learning in the discipline. To address this issue, a “history-based” intervention program entailing problem-solving and writing activities that instigate cognitive conflict was implemented. Data sources were pretest and posttest scores of a 12-theme questionnaire designed for this study called “Prospective teachers’ beliefs questionnaire about mathematics learning” and written reflections of prospective teachers. The survey of the prospective teachers beliefs related to the nature of mathematics and the way it is learned, taught, and practiced showed a great majority of them failed to hold progressive beliefs. Fortunately, the intervention program has helped the prospective teachers revise and correct their beliefs, thoughts, and understandings. Study of the prospective teachers’ written reflections and observations of their oral presentations during whole-class discussions strengthen the results of the quantitative study.     

Taking the Next Step: Ways Forward for Coaching Science

Coaching is no longer a subset of physical education or sport psychology but is rather an established vocation for research. In reaching such a position, we argue that a broad range of epistemologies have been used to investigate coaching such as sociology and cognitive psychology. However there is danger that, in the search for new ground, research becomes increasingly esoteric, having less and less impact on the domain that it is researching—namely coaching. As a step against this trend, we argue for and attempt to establish the commonalities across these research approaches suggesting that coaching is social, political, and pedagogical in nature. We accept that coaching is inherently complex but argue that coaches can be educated to cope with complexity through a professional judgment and nested decision making process. To facilitate this process, we offer a model for coaching that is inclusive of the commonalities across coaching research, summarizes our major theoretical points yet practical enough for application by coach educators and coaches.
