A Study of Current Noise in Cokes, Carbons, and Graphites

This study shows that current noise occurs when there is a deviation of Ohm\u27s Law, i.e., when the applied voltage and resultant current are no longer proportional. Since most, and perhaps all, cases of occurrence of frequency and current dependent noise are associated with non-linear devices, e.g., semiconductors, diodes, vacuum tubes, insulators near breakdown, it seems reasonable to seek a mechanism involving non-linearity as an important feature. Even though it may not be justifiable to seek a single mechanism to explain all of the occurrences of current noise, nevertheless, the fact that in cases studied and discussed herein the non-linearity is not a layer phenomenon (as in semiconductor devices), nor a space-charge effect (as in vacuum tube devices), but simply a result of heating the sample does seem to point to some single underlying cause

The Economic Model of Intercollegiate Athletics and Its Effects on the College Athlete Educational Experience

The financial growth and popularity of intercollegiate athletics presents unique and challenging opportunities to institutions of higher education. Intercollegiate athletics, specifically men’s basketball and football, elicit considerable media attention and publicity for these institutions. Yet, the current economic model of intercollegiate athletics engenders challenges to the academic welfare of athletes in both revenue and nonrevenue sports. This paper examines the challenges athletes incur as a result of the current economic model of intercollegiate athletics, and it poses several thought provoking questions to continue the debate on athletic reform

Une poétique du malaise : les anciens combattants face aux mythes de l’arrière (H. Barbusse, L.-F. Céline, L. Guilloux, E. M. Remarque, L. Werth)

Un bon nombre de romans européens des années 1910 à 1930 ayant pour thème l’expérience des combattants de la Grande Guerre, mettent en scène, à l’occasion de la démobilisation ou d’une permission de ces soldats, le malaise de ceux-ci face à la représentation déformée que le monde civil a de la guerre. Les combattants découvrent des civils qui se veulent, du fait de leur engagement « moral », aussi « héroïques » qu’eux, qui contestent leur vision « partielle » de l’état du front en prétendant à une « hauteur de vue » seule offerte par le recul de l’arrière. Pour représenter ce choc, le roman est d’autant plus efficace qu’il ne se livre pas à une rhétorique de la dénonciation : les personnages de combattants en question sont à la fois révoltés et passifs, opposés mais d’une certaine manière soumis à ces discours de la manipulation. Le « contre-récit » romanesque travaille donc de l’intérieur les discours manipulés, et n’offre pas pleinement les armes intellectuelles, idéologiques, pour s’en défaire : il invite le lecteur à s’interroger sur ces discours sans lui offrir, au-delà du pacifisme commun aux auteurs cités, la solution d’un engagement politique précis

A Social Identity Approach to Sport Psychology: Principles, Practice, and Prospects.

Drawing on social identity theory and self-categorization theory, we outline an approach to sport psychology that understands groups not simply as features of sporting contexts but rather as elements that can be, and often are, incorporated into a person's sense of self and, through this, become powerful determinants of their sport-related behavior. The underpinnings of this social identity approach are outlined, and four key lessons for sport that are indicative of the analytical and practical power of the approach are presented. These suggest that social identity is the basis for sports group (1) behavior, (2) formation and development, (3) support and stress appraisal, and (4) leadership. Building on recent developments within sport science, we outline an agenda for future research by identifying a range of topics to which the social identity approach could fruitfully contribute

A Microbiological Map of the Healthy Equine Gastrointestinal Tract.

Horses are exquisitely sensitive to non-specific gastrointestinal disturbances as well as systemic and extraintestinal conditions related to gut health, yet minimal data are available regarding the composition of the microbiota present in the equine stomach, small intestine, and cecum and their relation to fecal microbiota. Moreover, there is minimal information regarding the concordance of the luminal and mucosal microbial communities throughout the equine gut. Illumina-based 16S rRNA gene amplicon sequencing of the luminal and mucosal microbiota present in seven regions of the gastrointestinal tract of nine healthy adult horses revealed a distinct compositional divide between the small and large intestines. This disparity in composition was more pronounced within the luminal contents, but was also detected within mucosal populations. Moreover, the uniformity of the gut microbiota was much higher in the cecum and colon relative to that in the stomach, jejunum and ileum, despite a significantly higher number of unique sequences detected in the colon. Collectively, the current data suggest that while colonic samples (a proxy for feces) may provide a reasonable profile of the luminal contents of the healthy equine large intestine, they are not informative with regard to the contents of the stomach or small intestine. In contrast to the distinct difference between the highly variable upper gastrointestinal tract microbiota and relatively uniform large bowel microbiota present within the lumen, these data also demonstrate a regional continuity present in mucosal microbial communities throughout the length of the equine gut
