Applying the structure‐conduct‐performance framework in the media industry analysis

Abstract

This article reviews the application of the Industrial Organization (10) framework of Structure‐Conduct‐Performance (S‐C‐P) in media market research. The constructs and premises of this economic model are restated, and the orthodox economic notions of market performance and the logic that underlies the model are clarified. Alongside these elucidations, this article discusses common conceptualizations and interpretations found in media market studies. Media issues such as content diversity and media concentration, which are often studied through the S‐C‐P approach, are also re‐examined. These deliberations are intended to contribute toward a more consistent framework for the study of media industries and markets.     

A hedonic model of player wage determination from the Indian Premier League auction: Further evidence

A range of cross-sectional models are estimated with a view to establishing the factors that determine the valuation of professional athletes in a highly-specialised sport, with an application to cricket's Indian Premier League (IPL). We distinguish between personal characteristic and playing ability factors, and with respect to the former, between ability in different forms of the sport. We find a number of interpretable variables that have explanatory power over auction values, while decomposition according to batting and bowling specialisations produces very different results depending on the use of either Test or One-Day International (ODI) variables. There is also possible evidence of inefficient bidding, insomuch that overbidding was somewhat correlated with players with higher realised values.     

Benefits of omega‐3 supplementation for schoolchildren: Review of the current evidence

Despite the potential impact nutrition may have on learning, there have been surprisingly few papers published directed towards the educational research community. In contrast, omega‐3 supplementation studies are being frequently cited in the media, leading to parents asking for advice and guidance. The purpose of this article is to review the evidence to date for any effect of using omega‐3 supplementation in school‐aged children. This article focuses on the research that has been undertaken, particularly in relation to behaviour, education and cognitive development, in both typically developing populations as well as in children with specific learning difficulties and developmental disorders. Recommendations for future studies in this area have been highlighted in view of current knowledge. In conclusion, it was found that there is a shortage of properly controlled omega‐3 supplementation trials, particularly with typically developing children, to advocate the supplementation of all children with omega‐3 fatty acids, but due to the known importance of omega‐3 fatty acids in the brain and early development, further research is required.     

Male teacher shortage: black teachers’ perspectives

In this paper the authors draw on the perspectives of black teachers to provide a more nuanced analysis of male teacher shortage. Interviews with two Caribbean teachers in Toronto, Canada, are employed to illuminate the limits of an explanatory framework that foregrounds the singularity of gender as a basis for advocating male teachers as role models. The study concludes that educational policy attempting to address male teacher shortage would benefit from engaging with both analytic frameworks and empirical research that is capable of unravelling the politics of representation and intersectionality as they relate to addressing questions of male teacher shortage in elementary schools.     

The ABCs of New Zealand Sign Language: Aerial Spelling

Aerial spelling is the term given here for the way many deaf people in New Zealand, especially the elderly, manually represent letters of the alphabet. It is simply a system using the index finger to write letter(s) "in the air" and is an integral part of New Zealand Sign Language (NZSL). Unfortunately, recent research into NZSL is either dismissive of it or fails to acknowledge it. This article describes aerial spelling and discusses its nature, as well as its indifferent treatment in current literature.     

The precision of data obtained in large-scale science assessments: An investigation of bootstrapping and half-sample replication methods

Powerful computational procedures are now available to better determine the accuracy of statistical estimates derived from data that have unknown distributions or do not meet parametric requirements. These techniques are generally called resampling plans and include the recently developed bootstrap. Science educators often face the problem of nonnormal distributions especially when conducting large-scale assessments or evaluating national curriculum projects that require complex sampling plans. Resampling techniques permit the researcher to make inferences without the strong distributional assumptions needed for more traditional parametric approaches. In this study, the bootstrap and a simplified version of a half-sample replication are used to examine the precision of science test scores obtained in a large-scale evaluation of Scope, Sequence, and Coordination, a national science curriculum project. The resampling plans are described in some detail and the results are compared with those obtained from parametric methods. © 1998 John Wiley & Sons, Inc. J Res Sci Teach 35: 697–704, 1998.
