A Computer Scientist's Perspective on Chaos and Mystery

James E. Huchingson's Pandemonium Tremendum draws on a surprisingly fruitful analogy between metaphysics and thermodynamics, with the latter motivated through the more accessible language of communication theory. In Huchingson's model, God nurtures creation by the selective communication of bits of order that arise spontaneously in chaos.     

Vers une nouvelle appréhension des mathématiques par traitement EMDR : actualités et perspectives

ObjectiveEMDR for Eye Movement Desensitization and Reprocessing developed since 1989 by F. Shapiro has demonstrated its effectiveness in the treatment of Post Traumatic Stress Disorder (PTSD). In Science of Education, no study has been previously developed in the application of EMDR protocols. The purpose of this article is to demonstrate the relevance and effectiveness of EMDR in supporting cognitive and emotional remediation of students in Master 1, with respect to mathematics, preparing Schools Teacher contest. The first encounters with the students revealed, through their discourse, an aversion to mathematics linked to one or more particularly painful experiences in a learning situation. Mathematics may cause anguish, sometimes tinged beliefs such as “I’ll never be able to… I am very bad at math”. This represents even an insurmountable obstacle in the professional life of some.MethodsNearly 170 students in Master 1 “Professor of the Schools” registered on the ESPE (College of the Teaching profession and Education) were asked about their relation to mathematics, both in their emotions as their self-efficacy. Among those who suggested a traumatic memory in a learning situation in mathematics, forty were selected and divided into two groups. The control group received two hours of information about relaxation techniques that could be used before mathematics. The other group benefited of the EMDR treatment according to the standard protocol in eight phases.ResultsThe results showed that students who received EMDR treatment experienced after treatment and one month later, a significant decline in their negative emotions with mathematics and an increase in the strength of their self-efficacy, unlike the control group.DiscussionEMDR demonstrates its effectiveness in reprocessing beliefs and emotions of students with respect to mathematics and opens ways of research in Educational Sciences. So, it will be necessary, from the principle of alternated bilateral stimulation, to develop specific protocols for the struggling students, to measure the effects in the long term and develop them in a group situation.     

From an axiological standpoint

I maintain that intrinsic value is the fundamental concept of axiology. Many contemporary philosophers disagree; they say the proper object of value theory is final value. I examine three accounts of the nature of final value: the first claims that final value is non‐instrumental value; the second claims that final value is the value a thing has as an end; the third claims that final value is ultimate or non‐derivative value. In each case, I argue that the concept of final value described is either identical with the classical notion of intrinsic value or is not a plausible candidate for the primary concept of axiology.     

Talking Health With a Machine: How Does Message Interactivity Affect Attitudes and Cognitions?

By affording interactive communication and natural, human‐like conversations, can media tools affect the way we engage with content in human–machine interactions and influence our attitudes toward that content? A between‐subjects experiment (N = 172) examined the effects of two communication variables: (a) message‐interactivity and (b) conversational tone, in an online health information (Q&A) tool. Findings suggest that informal conversational tone lowers perceptions of relative susceptibility to health risks. Perceived contingency positively mediates the influence of message interactivity on individuals' health attitudes and behavioral intentions whereas perceived interactivity negatively mediates the relationships between these variables. These contrasting mediation effects are further explored via a phantom model analysis that tests two theoretically distinct paths, with implications for both theory and practice.     

p27和Cyclin E在子宫内膜腺癌中的表达及相关性分析

探讨p27和cyclinE蛋白表达在子宫内膜腺癌的发生、发展中的关系。采用免疫组织化学sP法,测定20例正常子宫内膜、10例不典型增生、40例内膜腺癌中p27、cyclin E蛋白的表达情况。p27蛋白在正常子宫内膜与内膜腺癌的阳性表达比较差异有显著性（P〈0．05）;cyclinE蛋白在正常子宫内膜与不典型增生及子宫内膜腺癌的表达相比较差异均有显著性（P〈0．05）。在子宫内膜腺癌中p27阳性表达率与cyclin E阳性表达率之间存在反向关系。     

Neuropsychological Contributions to the Early Identification of Alzheimer’s Disease

A wealth of evidence demonstrates that a prodromal period of Alzheimer’s disease (AD) exists for some years prior to the appearance of significant cognitive and functional declines required for the clinical diagnosis. This prodromal period of decline is characterized by a number of different neuropsychological and brain changes, and reliable identification of individuals prior to the development of significant clinical symptoms remains a top priority of research. In this review we provide an overview of those neuropsychological changes. In particular, we examine specific domains of cognition that appear to be negatively affected during the prodromal period of AD, and we review newer analytic strategies designed to examine cognitive asymmetries or discrepancies between higher-order cognitive functions versus fundamental skills. Finally, we provide a critical examination of the clinical concept of Mild Cognitive Impairment and offer suggestions for an increased focus on the impact of cerebrovascular disease (CVD) and CVD risk during the prodromal period of AD.     

Valuing time: Moderate download times can improve online goal pursuit

This research examines how the length of time for which a goal is interrupted affects goal pursuit, in an online context. Goal interruption duration in the form of long download time duration has been identified as a significant impediment to electronic commerce. It is believed that a faster download time is always better to motivate web users to keep surfing. We challenge this belief. In three studies, we find that, under certain circumstances, longer rather than shorter download times motivate web users to keep surfing longer. The counterintuitive pattern of effects can be explained by web users' fit experiences (Higgins, 2000) while surfing. In particular, our findings suggest that when online surfing “feels right”, web users think that online information is right.     

Achievement and self-concept of students with learning disabilities

The internal/external frame of reference (I/E) model by Marsh (Am Educ Res J 23:129–149, 1986) assumes that, besides social comparisons with their classmates, students engage in intraindividual, dimensional comparisons, comparing their own achievement in one subject with their achievement in other subjects. These dimensional comparison processes are assumed to result in negative paths from achievement in one subject (e.g., math) to self-concept in another (e.g., the verbal domain). In a study with N = 270 students, we investigated the generalizability of the I/E model to students with learning disabilities. Analyses showed positive correlations between math and German achievement and positive effects of achievement in both subjects on the corresponding domain-specific self-concept. Verbal and math self-concepts were almost uncorrelated. Moreover, there were negative effects of achievement in one domain on self-concept in the other. Our results therefore indicate that the I/E model can be generalized to students with learning disabilities.     

Perelman, ad Hominem Argument, and Rhetorical Ethos

Perelman’s view of the role of persons in argument is one of the most distinctive features of his break with Cartesian assumptions about reasoning. Whereas the rationalist paradigm sought to minimize or eliminate personal considerations by dismissing them as distracting and irrelevant, Perelman insists that argumentation inevitably does and ought to place stress on the specific persons engaged in an argument and that the relationship between speaker and what is spoken is always relevant and important. In taking this position, Perelman implicitly revives the classical conception of proof by character (ethos or “ethotic” argument), but despite an extended discussion of act and person in argument, The New Rhetoric does not give much consideration to the classical concept and confuses differing approaches to it within the tradition. The result is that Perelman treats the role of the speaker in argument only by reference to abstract techniques and does not recognize the importance of examining particular cases in order to thicken understanding of how ethotic argument works in the complex, situated context of its actual use. Consequently, Perelman’s account of the role of persons in argument should be supplement by reference to case studies, and to that end, I consider ethotic argument in W.E.B. Du Bois’ famous essay “Of Mr. Booker T. Washington and Others”.
