The recent literature on idiosyncratic volatility has documented three main empirical findings. First, Campbell, Lettau, Malkiel, and Xu (2001) show that idiosyncratic volatility exhibits an upward trend between 1962 and 1997. Second, Goyal and Santa-Clara (2003) find that aggregate measures of idiosyncratic volatility predict one-month-ahead excess market returns from 1962 to 1999. Third, Ang,...

Using standard speech corpora for development and evaluation has proven to be very valuable in promoting progress in speech and speaker recognition research. In this paper, we present an overview of current publicly available corpora intended for speaker recognition research and evaluation. We outline the corpora’s salient features with respect to their suitability for conducting speaker recogn...

This paper gives a historical overview of the ways various trends in the philosophy of science dealt with models and their relationship with the topics of heuristics and theoretical dynamics. First of all, N. Campbell’s account of analogies as components of scientific theories is presented. Next, the notion of ‘model’ in the reconstruction of the structure of scientific theories proposed by log...

1. What exactly is an evidenced-based practice? It usually means an approach that has established itself better than placebo or treatment as usual in two clinical trials. Such demonstrations are nothing to write home about; intervention of nearly any kind has demonstrated its superiority over placebo for 50 years! This research tells us nothing that we already do not know: Treatment works. So, ...

This paper reports on one dimension of a longitudinal study that researched the impact on student creativity of a unique intervention program for elementary students. The intervention was based on the National Profile and Statement (Curriculum Corporation, 1994a, 1994b) for the curriculum area of Technology. The intervention program comprised project-based, collaborative and thematically-integr...

The year was 1997. The news was amazing: a team of Scottish scientists that included Ian Wilmut and Keith Campbell had cloned a lamb from an adult sheep. Although Dolly had been born on July 5, 1996, the team had delayed the announcement to protect their ability to publish their work,1 which they did nearly eight months later in the science journal Nature.2 Dolly promptly became a media sensati...

Economists have recently argued recessions play a useful role in fostering growth. Yet a major source of growth, R&D, is procyclical. This paper argues one reason for procyclical R&D is a dynamic externality inherent to R&D that makes entrepreneurs short-sighted and concentrate their innovation in booms even when it is optimal to concentrate it in recessions. Additional forces may imply that pr...
