A statistical method for the serial comparison of vector cardiograms

In the absence of quantitative clinical standards to detect serial changes in cardiograms, statistical procedures are proposed as an alternative. These procedures are preceded by a dimension reducing orthonormal transformation of the original digitized cardiogram into a lower dimensional feature space. In feature space, mul-tivariate test criteria are given for the detection of changes in covariance matrices or mean vectors of the cardiograms. The flexibility is provided to compare the cardiograms of the same individual pairwise or simultaneously. Some pertinent remarks are also made about controlling the overall level of significance and its impact on the application of these techniques to cardiograms of USAF pilots.     

The geometry of legal principles

We discuss several possible legal principles from the standpoint of Bayesian decision theory. In particular, we show that a compelling legal principle implies compatibility with decisions based on maximizing the expected utility.     

The protestant ethic and the religious tattoo

This research illustrates how basic ideas from Weber's Protestant Ethic and the Spirit of Capitalism are reflected in religious individuals’ choices in obtaining tattoos. Qualitative responses to survey questions show that, among 60 university students who indicated they have one, religious tattoos reflect asceticism in their lives, point them to service (calling) in the name of God, or provide a level of assurance (or anxiety) regarding life after death. We offer this work as an illustration of how the essence of Weber's work persists in the popular culture of the 21st century.
