This study reports an application of the assimilation model, a theory of psychotherapeutic change, to an analogue study in which 43 students were asked to write for 20 minutes a day for 4 days ("Pennebaker paradigm") about a traumatic experience. Contrary to expectations based on previous research, participants who showed the greatest change in assimilation level and achieved the highest levels of assimilation during the study subsequently had more health-center visits than participants whose assimilation was less. Qualitative exploratory work suggested that there may be negative consequences of exposing traumatic experiences in the absence of supportive therapy to contain and fully integrate the experiences. A more measured approach to the benefits of brief exposition of traumatic experiences may be warranted. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A theoretical analysis of stress intensity factors and crack opening displacements for the double cleavage drilled compression specimen (DCDC) is presented. This specimen exploits a well known fact that the stress field around a circular hole in a plate subjected to uniaxial stress reverses sign at points on the hole which are parallel to the applied stress. Under uniaxial compression, tensile stresses exist at the edge of the hole and this tensile stress propagates a crack in the DCDC specimen. Because this tensile region is very localized, catastrophic crack growth cannot occur and it is not necessary to groove the specimen to promote straight crack growth. The controlled crack growth possible with this specimen should make it possible to examine fracture mechanisms in detail. The simplicity of this test specimen also makes it an ideal candidate for studying environmental effects on fracture.
Résumé On présente une analyse théorique des facteurs d'intensité de contraintes et des déplacements d'ouverture de fissure pour une éprouvette donnée de compression à double clivage (DCDC). Ce type d'éprouvette exploite le fait bien connu que le champ de contraintes autour d'un trou circulaire dans une plaque soumise à contraintes uniaxiale change de signe dans les zones du trou parallèle à la tension appliquée. Sous compression uniaxiale, des tensions existent au bord du trou et ces tensions induisent la propagation d'une fissure dans l'éprouvette DCDC. Comme la zone concernée est trés localisée, il ne peut survenir de croissance catastrophique de la fissure, et il n'est pas nécessaire d'entailler l'éprouvette en vue de provoquer une propagation droite de la fissure. Le fait de pouvoir contrôler la croissance de la fissure dans ce type d'éprouvette devrait rendre possible l'examen en détail des mécanismes de rupture. La simplicité de cette éprouvette d'essai en fait également une candidate idéale pour l'étude de effets de l'environnement sur la rupture.相似文献

Assessed 25 outpatients via the Rorschach assessment prior to short-term, dynamic therapy to see whether patient characteristics would predict outcome in intrapsychic organization, as measured with L. S. Benjamin's (see record 1975-02991-001) Structural Analysis of Social Behavior (SASB). SASB and other outcome measures were administered after termination of psychodynamic therapy. Findings show good predictive value of the Rorschach developmental dimensions Differentiation and Articulation in predicting an Introject change outcome index.

The effects of 0.3 and 0.6 mg/kg methylphenidate were analyzed in a double-blind, placebo-controlled, cross-over study in which 17 boys (ages 7.8–9.9 yrs) with attention deficit hyperactivity disorder (ADHD) played in baseball games. Drug effects were evaluated on children's attention during the game, as indictated by their on-task behavior on the field and their ability to answer questions about the status of the game at all times. Judgment during batting, batting skill during the game, and performance on skill drills prior to the game were also assessed as a function of medication. Results revealed that methylphenidate had a beneficial effect on attending during the game. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Responds to R. P. Sloan and E. Bagiella's (see record 2001-06506-009)comments on the M. E. McCullough, et al (see record 2000-03769-001) article regarding religious involvement and morality. McCullough et al note that Sloan and Bagiella compared their findings with results from individual studies of hopelessness and physical activity that used criteria other than morality. The present authors argue that such comparisons are meaningless. Sloan and Bagiella's questioning of the statistical nonsignificance of the fully adjusted association is addressed. Methodological issues are also discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

This paper documents the effect of stress and temperature on the cyclic minimum strain rate at two different loading frequencies
for the oxide dispersion strengthened (ODS) superalloy, INCONEL* MA 6000. The apparent stress exponent and activation energy
for cyclic creep at both frequencies studied are shown to be greater than values observed for static creep. The large values
of the stress exponent and activation energy for cyclic creep are proposed to result from anelastic strain storage delaying
nonrecoverable creep during the on-load portion of the cyclic creep loading, such that the “effective stress” driving nonrecoverable
creep is only a small fraction of the applied stress. In addition, the temperature dependence of the anelastic relaxation
that occurs during the off-load portion of the cyclic creep loading is determined. The activation energy found for the relaxation
process is equal to about one-half that for self-diffusion in nickel. A mechanism of localized climb of dislocations over
the oxide dispersoids present in INCONEL MA 6000 is postulated to account for the observed activation energy of the relaxation
process.

We empirically examined S. H. Budman and A. S. Gurman's (see record 1984-04498-001) theoretical proposals concerning major differences in the value systems of long- vs. short-term therapists. Ss were 222 randomly selected licensed psychologists who indicated their preferred approach (short-term or long-term). Values were assessed with a scale designed for the study. Overall, results indicate that therapists who prefer a short-term approach are more likely to endorse the proposed values of the short-term therapist than are therapists who prefer a long-term approach. This finding held even after the authors controlled for the significant contributions of theoretical orientation and therapeutic practice variables. Specifically, short-term (vs. long-term) therapists believed more that psychological change could occur outside of therapy and that setting time limits would intensify the therapeutic work. Implications for the practice of brief therapy are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
