Career and Career-Related Educational Concerns of College Students With Disabilities

This article providas career counselors with an overview of career-related issues relevant to students with disabilities in postsecondary educational settings. Topics addressed include the impact of disability on career development, the impact of disability on postsecondary educational participation, and access and accommodation issues. The authors argue for an expanded role for career counselors who work with college students with disabilities. It is concluded that career counselors can play an important role in facilitating college students with disabilities in their adaptation to the college environment, their acquisition of appropriate accommodations, and their transition to employment.     

Perelman's rhetorical foundation of philosophy

This article is a Gadamer-Perelman's debate. The author points out the limits of the gadamerian's hermeneutic conception of philosophy and criticizes this conception from Perelman's new rhetoric point of view. Instead of speaking of truth as an ontological originary experience, the rhetorical foundation of philosophy allows us to say that in philosophy the important is the contrastation and the confrontation of criteria and that, for that reason, philosophy is above all characterized by discussibility.Philosophical argumentation, like juridical argumentation, constitutes applications, to different domains, of a theory of argumentation which we consider as a new rhetoric.By identifying this theory with the general theory of persuasive speech, which seeks to obtain the intellectual as well as the emotional adherence of an audience, no matter which, we state that all speeches which do not aspire to an impersonal validity proceed from rhetoric. (Ch. Perelman,L'empire rhétorique, p. 177).But, if one does not admit that the philosophical thesis may be founded on evident intuitions, it will be necessary to reccur to argumentative technics to make them prevail. The new rhetoric then becomes the indispensable tool of philosophy. (Ch. Perelman,L'empire rhétorique, p. 21).

The development of modern programmable pacemaker-systems has led to a series of questions which until now have apparently not existed in the treatment of cardiac rhythm disturbances. These questions touch especially on the problem of whether the relation which usually exists between a diagnostic step and its therapeutic consequence, namely its therapeutic relevance, is abolished or at least changed.     

Attention training toward and away from threat in social phobia: effects on subjective, behavioral, and physiological measures of anxiety

Social phobics exhibit an attentional bias for threat in probe detection and probe discrimination paradigms. Attention training programs, in which probes always replace nonthreatening cues, reduce attentional bias for threat and self-reported social anxiety. However, researchers have seldom included behavioral measures of anxiety reduction, and have never taken physiological measures of anxiety reduction. In the present study, we trained individuals with generalized social phobia (n = 57) to attend to threat cues (attend to threat), to attend to positive cues (attend to positive), or to alternately attend to both (control condition). We assessed not only self-reported social anxiety, but also behavioral and physiological measures of social anxiety. Participants trained to attend to nonthreatening cues demonstrated significantly greater reductions in self-reported, behavioral, and physiological measures of anxiety than did participants from the attend to threat and control conditions.     

Dorsal striatal dopamine depletion impairs both allocentric and egocentric navigation in rats

Successful navigation requires interactions among multiple but overlapping neural pathways mediating distinct capabilities, including egocentric (self-oriented, route-based) and allocentric (spatial, map-based) learning. Route-based navigation has been shown to be impaired following acute exposure to the dopaminergic (DA) drugs (+)-methamphetamine and (+)-amphetamine, but not the serotoninergic (5-HT) drugs (±)-3,4-methylenedioxymethamphetamine or (±)-fenfluramine. The dopaminergic-rich neostriatum is involved in both allocentric and egocentric navigation. This experiment tested whether dorsal striatal DA loss using bilateral 6-hydroxydopamine (6-OHDA) injections impaired one or both types of navigation. Two weeks following 6-OHDA injections, rats began testing in the Cincinnati water maze (CWM) followed by the Morris water maze (MWM) for route-based and spatial navigation, respectively. 6-OHDA treatment significantly increased latency and errors in the CWM and path length, latency, and cumulative distance in the MWM with no difference on cued MWM trials. Neostriatal DA levels were reduced by 80% at 2 and 7 weeks post-treatment. In addition, 6-OHDA increased DA turnover and decreased norepinephrine (NE) levels. 6-OHDA injections did not alter monoamine levels in the prefrontal cortex. The data support that neostriatal DA modulates both types of navigation.
