The Relationship between Science and Religion: Complexity Rules the Day, and Many Windows and Maps Are Needed

In a recent paper, Kowalski and Mrdjenovich (2017) advised against indiscriminate dichotomization. We looked at nature vs nurture, reductionism vs holism, and several of the ways the scientific pie could be sliced in two pieces, basic vs applied, physical science vs social science, etc., arguing that focusing on one or the other of two dichotomous choices often deflects attention from a more fertile intermediate ground where more useful answers might be found, and that a better classification scheme than the basic/applied opposition would depend on the nature of the question being asked and the manner in which an answer is sought. We even ventured to include science vs poetry, recognizing that the two are often taken to be the very embodiment of polarity, the cold of rationality vs the heat of emotion. Thus we approached, but did not directly confront the elephant in the room: Science vs Religion. I attend to this now

Relationship Between Smoking and Calculus Deposition

The chi-square test for association in contingency tables is often used to analyze data gathered during the course of dental/oral experimentation. A simple procedure that makes such analyses more useful is described, and the method is applied in a study of the relationship between smoking and calculus deposition.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66590/2/10.1177_00220345710500010101.pd

Anti-Scientific Currents in American Thought

Multifarious forces have surrounded science and continue their—sometimes separate, sometimes coordinated—attempts to supplant a scientific approach to an explanation of important questions about us and the world we inhabit. We focus here on questions pertaining to biology and medicine, but no aspect of the scientific enterprise is immune from attack; and not all of the forces aligned against it are represented. The ones considered are: religion, neoliberalism, postmodernism, the “back-to-nature” movement, bioethical obstructionism, and the current POTUS, Donald Trump. We sit in amazement that at the amount of vitriol that has been leveled at science, but try to maintain civility in response. We would be irenic, not polemic; promoting true dialogue between respected scholars holding somewhat differing views. This is not as difficult as some would have you believe

Analysis of Longitudinal Data in Craniofacial Research: Some Strategies

Although it is generally acknowledged that longitudinal data provide the most information on growth and development and other time-dependent phenomena, such data are often analyzed by conventional (cross-sectional) statistical methods. This widespread practice ignores the distinctive characteristics (e.g., covariance structure) of longitudinal data and may yield misleading results. The purpose of this article is to present some strategies and make available computer programs for the appropriate analysis of longitudinal data. User-friendly PC programs for the estimation of average growth curves, computation of tracking indices, prediction of future values, diagnosis, classification, clustering, estimation of missing values, and testing hypotheses concerning individual and group differences are presented. Benefits of these methods over the usual techniques are illustrated with the example of maxillary growth in the rhesus monkey.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67976/2/10.1177_10454411940050030101.pd
