Revesz, Peter, and Shasha Wu. “Spatiotemporal reasoning about epidemiological data.” Artificial Intelligence In Medicine no. 2 (2006): 157.

Abstract: In this article, we propose new methods to visualize and reason about spatiotemporal epidemiological data. Efficient computerized reasoning about epidemics is important to public health and national security, but it is a difficult task because epidemiological data are usually spatiotemporal, recursive, and fast changing hence hard to handle in traditional relational databases and geographic information systems. We describe the general methods of how to (1) store epidemiological data in constraint databases, (2) handle recursive epidemiological definitions, and (3) efficiently reason about epidemiological data based on recursive and non-recursive Structured Query Language (SQL) queries. We implement a particular epidemiological system called West Nile Virus Information System (WeNiVIS) that enables the visual tracking of and reasoning about the spread of the West Nile Virus (WNV) epidemic in Pennsylvania. In the system, users can do many interesting reasonings based on the spatiotemporal dataset and the recursively defined risk evaluation function through the SQL query interfaces. In this article, the WeNiVIS system is used to visualize and reason about the spread of West Nile Virus in Pennsylvania as a sample application. Beside this particular case, the general methodology used in the implementation of the system is also appropriate for many other applications. Our general solution for reasoning about epidemics and related spatiotemporal phenomena enables one to solve many problems similar to WNV without much modification.

Abstract: Responds to a comment by Franco Orsucci (see record 2007-00094-005) on the original article by Karen Klein Villa et al (see record 2007-00094-002). The authors are grateful to the commentators for their scholarly and thought-provoking response to our target article and for the interesting theoretical and technical questions their response has generated. The Shevrin group has engaged in a long tradition of subliminal perception studies addressing a number of phenomena regarding primary- and secondary-process mentation, including physiological markers of unconscious conflict, affect, defense, and the attributional vs. relational nature of these two modes of processing. The current study focuses on the nature of language processing in the unconscious, where we hypothesized that words would be treated as perceptual stimuli and processed in a bidirectional manner. We sought to determine if the structural aspect of a lexical item was processed separately from its referent or semantic associate. This type of lexical modularity was postulated early on by Freud and has been outlined in contemporary models of language architecture. As stated previously, our palindrome finding did not emerge as a main effect; however, once the moderating variables of stimulus detectability and anxiety were taken into account, the perceptual treatment of words in the subliminal condition did emerge. In particular, high anxiety activated semantic associations and low anxiety inhibited semantic associations to the palindrome prime. We propose, therefore, that novel and creative sequencing of linguistic units (i.e., the word is treated as a perceptual object) predominates in unconscious cognitive processing and that this novel sequencing potentially contributes to ambiguity exploitation and resolution for such processes as condensation and displacement.

Abstract: One of Freud’s seminal hypotheses first appearing in his monograph On Aphasia (1891) posited that word meaning and word presentation (e.g., phonemic and graphemic properties) needed to be distinguished if aphasic symptoms were to be accurately understood. In his later psychoanalytic writing, this supposition was generalized to refer to the primary-process uses of language in dreams, symptom formation, and unconscious processes (1900, 1915). To test Freud’s hypothesis that word meaning and word presentation are functionally distinct when processed unconsciously (Freud, 1891, 1915), 50 participants were tested with a priming paradigm in which a “palindrome” prime, presented either subliminally or supraliminally, was followed by two target alternatives. In the forward condition, the prime (e.g. DOG) was followed with a semantic associate (e.g. CANINE) and a distractor. In the “palindrome” condition, the prime was followed with a semantic associate of the reversed word (e.g. ANGEL) and a distractor. The participants’ task was to choose the word they preferred. The supraliminal results confirm classical semantic priming, but only in the forward condition. Subliminally, however, while no main results emerged, there were interaction effects with self-rated personality factors and stimulus detectability. High trait anxiety induced priming facilitation, while in low anxiety there was inhibition, for both forward and palindrome conditions. On the other hand, high scores on the Hysteroid-Obsessoid Questionnaire, a measure of repressiveness, led to inhibition of the priming effect while facilitation was observed with low scores–but only for forward priming. Consistently, these interaction effects were even stronger when stimulus detectability was low than at higher levels of detectability, ruling out any skeptical account that the measured effects might be due to residual conscious perception. Taken together, these findings support Freud’s hypothesis that the perceptual object dimension of a word, being functionally distinct from its meaning, can give rise to novel sequential processing, an effect that is more likely to occur unconsciously (i.e., d́′ ≤ 0) and under conditions of anxiety.

White, Charles Edward.God by the numbers: coincidence and random mutation are not the most likely explanations for some things.” Christianity Today 50, no. 3 (March 1, 2006): 44-47.

Abstract: Math and theology have had a long and checkered relationship. The Babylonians and Mayans both associated numbers with God. In fact, both societies named their gods with numbers. The Mayans used 13 and the Babylonians used 60. In the Greek world, followers of Pythagoras prayed to the first 4 numbers and thought they were the creator. On the other hand, in the 18th century, the French mathematician Laplace told Napoleon he had no need of God even as a hypothesis, and in 1744, John Wesley confessed: “I am convinced, from many experiments, I could not study either mathematics, arithmetic, or algebra … without being a deist, if not an atheist.”

Buratovich, Michael. “Dawkin’s God: Genes, Memes, and the Meaning of Life.” Christian Scholar’s Review 35, no. 2 (Winter, 2006): 280-283.

Abstract: With respect to Dawkins’ refutation of William’Paley’s “God as the Divine Watchmaker” hypothesis, McGrath points out that Paley’s Natural Theology “represents the late and final flowering of a movement that came into being in the aftermath of the great Newtonian revolution of the late seventeenth century, and which had completely lost its way by the middle of the eighteenth century” (69). Finally, the quote from River out of Eden that speaks of DNA as digital information and creatures as survival machines that act as mere vessels to carry this information can hardly mean that Dawkins wishes to reduce all social behavior to kin selection, since he said as much about human behavior in The Selfish Gene.

Abstract: This Michigan Family Review explores the influence of technology on developing individuals and families. Technologies examined include domestic technologies, information technologies, and mass media. Individual development, family tasks, peer relationships, gendered work and communication, and family interventions are discussed through the lens of technological change.
