In questioning Kamstra, Kramer, and Levi’s (2003) finding of an economically and statistically significant seasonal affective disorder (SAD) effect, Kelly and Meschke (2010) make errors of commission and omission. They misrepresent their empirical results, claiming that the SAD effect arises due to a ‘‘mechanically induced’’ effect that is non-existent, labeling the SAD effect a ‘‘turn-of-year’...

There is a growing acknowledgement that many countries face serious social inequalities in health, identified as one of the greatest challenges to public health today. ‘‘Social inequalities in health’’ in this article are defined as systematic differences in health between different socioeconomic groups within a society. As they are socially produced, they are potentially avoidable and are wide...

This paper investigates the processing of conditional sentences and sentences with ‘since’ in two respects. Firstly, we investigate the clausal implicature originating from the scale . Secondly, we investigate how modals can affect the interpretation of these sentences. A reading time experiment is reported which involved these two factors. It appears that ‘since’ is pr...

In situ methods for estimating water quality parameters would facilitate efforts in spatial and temporal monitoring, and optical reflectance sensing has shown potential in this regard, particularly for chlorophyll, suspended sediment, and turbidity. The objective of this research was to develop and evaluate relationships between hyperspectral remote sensing and lake water quality parameters-chl...

Digital image data are now commonly used throughout the field of solar physics. Many steps of image data analysis, including image co-alignment, perspective reprojection of the solar surface, and compensation for solar rotation, require re-sampling original telescope image data under a distorting coordinate transformation. The most common image re-sampling methods introduce significant, unneces...

This commentary offers several directions for the development of Chinese management research based on the penetrating analyses provided by Barney and Zhang (2009) and Whetten (2009). First and foremost, Chinese management researchers can develop novel, seminal ideas and theories that are not necessarily tied to the Chinese cultural context but are applicable in diverse cultural contexts. The su...

While the Surgeon General's Consumer Guide lists weight-gain as an important relapse trigger, the 2001 Surgeon General's Report on Women and Smoking concludes, paradoxically, that "actual weight-gain during cessation does not appear to predict relapse." This dichotomous view reflects longstanding scientific uncertainty about the role of weight-gain in triggering relapse. This scientific uncerta...

Economics is primarily a non-experimental science. Typically, we cannot generate new data sets on which to test hypotheses independently of the data that may have led to a particular theory. The common practice of using the same data set to formulate and test hypotheses introduces data-snooping biases that, if not accounted for, invalidate the assumptions underlying classical statistical infere...
