and two anonymous referees for helpful comments. Anil Arya gratefully acknowledges assistance from the John J. Abstract Despite the influx of measures which can be customized to the demands of each business unit (e.g., customer satisfaction surveys and quality indices), many firms have been dogged in their reliance on standardized measures (e.g.,(More)
A delayed gamma distribution satisfactorily described the distribution of times to hatching of Ostertagia circumcincta eggs incubated in 0.1% saline at temperatures between 6 and 20 degrees C. Below 6 degree C hatching of eggs was extremely variable. The relationship between rates of development and temperature within the range 10 to 20 degrees C was more(More)
We study a firm's decisions to engage in socially responsible activities, voluntarily report on them and purchase external assurance of the report. In our signaling model, neither firm type nor the level of activity is observed. We show that if voluntary assurance is not too expensive, the firm that engages in more socially responsible activities purchases(More)

When IEEE Software asked me to contribute to a debate between advocates of Linux and NT, my reaction was one of genuine surprise. If IEEE thinks there is a debatable issue between open standards as illustrated by the Linux OS and the proprietary standards as implemented in NT, then, as the saying goes, Houston, we have a problem. IEEE is a standards body.(More)
While a variety of statistical models now exist for the spatio-temporal analysis of two-dimensional (surface) data collected over time, there are few published examples of analogous models for the spatial analysis of data taken over four dimensions: latitude, longitude, height or depth, and time. When taking account of the autocorrelation of data within and(More)
