The effect of smoothing functions on data obtained from a FFT

This research investigated the effect on power spectra when data-smoothing functions were used on EEG data prior to submitting them to a FFT. We used two smoothing function options: not using any smoothing function and using the Parzen smoothing function. We developed a program to evaluate each of these functions with real and standard data. When a set of data is submitted to smoothing prior to being submitted to a FFT, there are statistically significant differences in the power spectra obtained from the FFT. This finding holds true for standard waveforms as well as for real EEG data.     

Theology's munus triplex? Reconsidering Theology's Relationship to the Sciences

Despite the complicated history of exchange between theology and science, the relation between the two can perhaps be summarized succinctly by Ian Barbour's influential taxonomy: conflict, independence, dialogue or integration. This article explores an alternative route by demonstrating how three recent theologians (Barth, Van Huyssteen and Webster) offer recognizably distinct visions for Christian theology's interdisciplinary encounters which can be characterized respectively as prophetic, priestly and royal. A second section of this article discusses the fruitfulness of adopting a munus triplex approach to the interdisciplinary question, as well as anticipating potential objections to transferring the ‘offices’ of Christ to the task of theology.     

A cross-validation of sex differences in the expression of depression

A considerable amount of evidence has accumulated indicating a greater rate of depression among females compared to males. In addition, recent investigations have revealed distinct patterns of depressive responding as a function of sex. The present study provided a cross-validational test of findings reported by Funabiki and colleagues. Male and female college students indicated the likelihood that they would engage in 79 behavioral analytically derived behaviors or cognitions if depressed. Stepwise discriminant function analyses were performed to determine maximum separation of male and female responses. This procedure yielded a 55.6% overall variable cross-validation rate. Many of the findings were consistent with Radloff and Rae's theoretical view of sex differences in learned susceptibility to depression. The data also suggest several avenues for future research and support the utility of investigating theories of depression within the context of a continuity between normal mood states and depressive phenomena.Useful comments on an earlier draft of this article were provided by Mark Hammarlund and Lorence S.
