Spatial asymmetries are an intriguing feature of directed attention. Recent observations indicate an influence of temperament upon the direction of these asymmetries. It is unknown whether this influence generalises to visual orienting behaviour. The aim of the current study was therefore to explore the relationship between temperament and measures of spatial orienting as a function of target hemifield. An exogenous cueing task was administered to 92 healthy participants. Temperament was assessed using Carver and White's (1994) Behavioural Inhibition System and Behavioural (...) Activation System (BIS/BAS) scales. Individuals with high sensitivity to punishment and low sensitivity to reward showed a leftward asymmetry of directed attention when there was no informative spatial cue provided. This asymmetry was not present when targets were preceded by spatial cues that were either valid or invalid. The findings support the notion that individual variations in temperament influence spatial asymmetries in visual orienting, but only when lateral targets are preceded by a non-directional (neutral) cue. The results are discussed in terms of hemispheric asymmetries and dopamine activity. (shrink)

Prior research supports the learnability of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition Alternative Model of Personality Disorders. However, researchers have yet to compare novice ratings on the AMPD’s Level of Personality Functioning Scale and the 25 pathological personality traits with expert ratings. Furthermore, the AMPD has yet to be examined with the idiographic Shedler-Westen Assessment Procedure. We compared the aggregated AMPD clinical profile of a group of psychology doctoral students who learned the AMPD to high levels (...) of reliability to that of an expert rater using the crucible of the classical case of “Madeline G.” Examination of AMPD and SWAP ratings of “Madeline G.” revealed excellent overall concordance but suggests that novice raters tend to perceive lower levels of personality impairment.

BackgroundScientists communicate progress and exchange information via publication and presentation at scientific meetings. We previously showed that text similarity analysis applied to Medline can identify and quantify plagiarism and duplicate publications in peer-reviewed biomedical journals. In the present study, we applied the same analysis to a large sample of conference abstracts.MethodsWe downloaded 144,149 abstracts from 207 national and international meetings of 63 biomedical conferences. Pairwise comparisons were made using eTBLAST: a text similarity engine. A domain expert then reviewed random samples (...) of highly similar abstracts to estimate the extent of text overlap and possible plagiarism.ResultsOur main findings indicate that the vast majority of textual overlap occurred within the same meeting and between meetings of the same conference, both of which were significantly higher than instances of plagiarism, which occurred in less than.5% of abstracts.ConclusionsThis analysis indicates that textual overlap in abstracts of papers presented at scientific meetings is one-tenth that of peer-reviewed publications, yet the plagiarism rate is approximately the same as previously measured in peer-reviewed publications. This latter finding underscores a need for monitoring scientific meeting submissions – as is now done when submitting manuscripts to peer-reviewed journals – to improve the integrity of scientific communications.

Directed cell migration is a fundamental component of numerous biological systems and is critical to the pathology of many diseases. Although the importance of secreted chemoattractant factors in providing navigational cues to migrating cells bearing specific chemoattractant receptors is now well‐established, how the function of these factors is regulated is not so well understood and may be of key importance to the design of new therapeutics for numerous human diseases. While regulation of migration clearly takes place on a number of (...) different levels, it is becoming clear that so‐called ‘atypical’ receptors play a role in scavenging, or altering the localisation of, chemoattractant molecules such as chemokines and complement components. These receptors do this through binding and/or internalising their chemoattractant ligands without activating signal transduction cascades leading to cell migration. The atypical chemokine receptor family currently comprises the receptors D6, DARC and CCX‐CKR. In this review, we discuss the evidence from in vitro and in vivo studies that these receptors play a role in regulating cell migration, and speculate that other orphan receptors may also belong to this family. Furthermore, with the advent of gene therapy on the horizon, the therapeutic potential of these receptors in human disease is also considered.

Chemokines (chemotactic cytokines) drive and direct leukocyte traffic. New evidence suggests that the unusual CCR6/CCL20 chemokine receptor/ligand axis provides key homing signals for recently identified cells of the adaptive immune system, recruiting both pro‐inflammatory and suppressive T cell subsets. Thus CCR6 and CCL20 have been recently implicated in various human pathologies, particularly in autoimmune disease. These studies have revealed that targeting CCR6/CCL20 can enhance or inhibit autoimmune disease depending on the cellular basis of pathogenesis and the cell subtype most affected (...) through different CCR6/CCL20 manipulations. Here, we discuss the significance of this chemokine receptor/ligand axis in immune and inflammatory functions, consider the potential for targeting CCR6/CCL20 in human autoimmunity and propose that the shared evolutionary origins of pro‐inflammatory and regulatory T cells may contribute to the reason why both immune activation and regulation might be controlled through the same chemokine pathway.

The essays in Part I of _Beyond Poststructuralism seek_ to demonstrate fallacies of structuralist and poststructuralist thought that remain potent even though the theoretical structures that led to their enunciation have lost much of their original influence. These fallacies include the idea that one must avoid the consideration of authorial intention; that meanings are undecidable; that there is no justification for seeking unity in a text; that all hierarchies of value are reversible; that history is no more than an open (...) contest among competing narrative constructions; and that the very nature of language makes the falsifiability of statements about human experience impossible. The essays in Part II suggest ways to bring literary study into closer relation with human experience of the world. Their authors emphasize the role of literature in providing new perspectives and broadening the range of available alternatives to what is threatening, unjust, fallacious, or absurd in social and cultural structures. Contributors are Bernard Bergonzi, John Holloway, Wendell V. Harris, A. D. Nuttall, Raymond Tallis, John Searle, Richard Levin, Robert Scholes, James Battersby, David Bromwich, Quentin Kraft, Michael Fischer, Charles Altieri, Christopher Clausen, Gayle Greene, André Lefevere, Daniel R.

Theologie und Metaphysik stehen in einem Spannungsverhältnis. Versuchen der Rehabilitierung eines starken metaphysischen Systemsdenkens steht das 'nachmetaphysische Denken' entgegen, welches das Projekt einer rationalen Metaphysik verabschiedet. Wendel und Breul unternehmen einen Vermittlungsversuch: Sie formulieren eine 'Metaphysik nach Kant' als Leitparadigma der Theologie, die ernst nimmt, dass Metaphysik für eine rationale Begründung des Glaubens unverzichtbar ist, sie zugleich jedoch methodisch nur in der Verwurzelung in einer Praxis personaler Lebensformen haltbar ist. So gelingt es diesem Neuansatz, eine an die Moderne anschlussfähige praktische (...) Begründung religiöser Hoffnung zu entwickeln."-- Back cover. (shrink)
