M. Rothbart and B. Park (1986) demonstrated that, consistent with the common negativity bias, positive traits are difficult to confirm and easy to disconfirm, whereas the opposite is true for negative traits. This article extends their analysis by showing that trait (dis-)confirmability is moderated by trait content (warmth vs. competence). Study 1 identifies a trait sample representative of warmth and competence. Study 2 shows a strong negativity effect for warmth and a reduced (or absent) negativity effect for competence. Study 3 examines trait properties related to the behavioral range of the trait possessor and to the motivational goals of the perceiver as predictors of trait (dis-)confirmability. The theoretical and practical implications of the authors' findings are discussed, and avenues for future research are suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

This paper provides simplified correlation models for CO/H2 chemical reaction times. The procedure used for the CO/H2 simplified modeling utilized the full chemical kinetics mechanism run over a range of temperatures from 700 to 1800 K, pressures from 0.5 to 50 atm, mixtures from 0% to 95% CO, and equivalence ratios from 0.2 to 2.0 to determine ignition (or reaction) time. The correlations for ignition times are given in formulas as functions of equivalence ratio, temperature, and pressure. Two different forms of correlations were obtained, one being a single, overall correlation and the other a two-stage correlation representing regions of high and low temperatures. These correlations are shown to work well over a range of chemical time scales spanning ten orders of magnitude. The correlations are also compared with measured data from the literature. 相似文献

Factors liable to limit the validity of liquid sample analysis by electron microprobe are investigated. For lyophilized samples composed of large 2–6 μm crystals, linear calibration curves may still be obtained for Na, Mg, P, Cl, K and Ca by raising the accelerating voltage to 18 kV, provided the X-ray take-off angle of the electron microprobe is 40°. Routinely prepared lyophilized samples are composed of discrete crystals. Their size is reproducible, depending on the composition of the dried deposit, and ranges from 0.1 to 0.5 μm for deposits mainly composed of NaCl. Within this range, the proportionality of X-ray intensity to concentration is not affected by particle size. The concentration range for which X-ray intensities remain proportional to concentrations is experimentally determined for the six elements above as a function of sample mass thickness and accelerating voltage. For certain elements, the proportionality constant is shown to vary with the composition of the solution. As regards chlorine concentration determinations, analysis of plasma ultrafiltrate and recovery experiments suggest that the proportionality constant is definitely 10% higher for this ultrafiltrate than for standard solutions. 相似文献

A silicon on sapphire nonlinear waveguide which can be used for all-optical logic operation is described. A theoretical analysis confirms that the fast switchings experimentally observed using this device result from a competition between electronic and thermal nonlinear effects occurring in silicon. Numerical simulations display the influence of various parameters on the device operation conditions as an optical switch or bistable device. 相似文献

Twenty-nine patients with obsessive-compulsive disorder as diagnosed in accordance with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised; American Psychiatric Association, 1987) who did not have overt compulsive rituals were randomly assigned to treatment and waiting-list conditions. Patients in the treatment condition received cognitive-behavioral therapy consisting of a detailed explanation of the occurrence and maintenance of obsessive thoughts, exposure to obsessive thoughts, response prevention of all neutralizing strategies, cognitive restructuring, and relapse prevention. Compared with waiting-list patients, treated patients improved significantly on measures of severity of obsessions, current functioning, self-report obsessive-compulsive symptoms, and anxiety. When waiting-list patients were subsequently treated, the combined group improved on all outcome measures. Treatment gains were maintained at 6-month follow-up. Results indicate that cognitive-behavioral therapy is effective in the treatment of patients with obsessive thoughts, a group that has often been considered resistant to treatment.

Modern distributed memory parallel computers provide hardware support for the efficient and reliable delivery of interprocessor messages. This facility needs to be accessed by lightweight protocols that do not waste the performance of the underlying hardware; the heavyweight layering techniques traditionally used in distributed systems are wholly inappropriate. A low-level communication interface is therefore presented which exploits modern architectures effectively, while maintaining a good match to existing parallel programming environments. The interface defines mechanisms to access an asynchronous reliable packet delivery service. It permits messaging protocols to be efficiently synthesized by considering the activity at their end-points alone. This arrangement effectively decouples the implementation of protocols from low-level architectural features, and hence aids the portability of parallel programming environments. Furthermore, the interface allows the communication network to be shared by multiple programming paradigms, giving additional flexibility over existing systems 相似文献

In recent years, cognitive–behavioural interventions have proven to be effective in the treatment of Panic Disorder with Agoraphobia (PDA). However, there is controversy concerning treatment efficacy of PDA for patients with a comorbid diagnosis of Personality Disorder (PD). This study evaluates the impact of a PD on PDA treatment response. 81 patients suffering from PDA were recruited from a cognitive–behavioural group treatment program. Diagnoses on Axis I (N?=?81) and Axis II (N?=?36) were made at treatment onset according to Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) criteria. Validated questionnaires were used to assess agoraphobia at treatment onset, following treatment, and at the 3 mo follow-up. All patients improved markedly from pretest to posttest and at the 3 mo follow-up. Grouping of patients according to the presence or absence of a personality disorder revealed significant differences between the groups on pre- and posttreatment scores on agoraphobia. Results also reveal that patients with a personality disorder improve more slowly than patients without a personality disorder. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In a recent paper [5], it was shown that dry polycarbonate craze growth kinetics are compatible with a propagation mechanism
based on the creep of craze material. Further confirmation of such a mechanism is found in the lack of variation of crazing
kinetics with thermal pretreatment, as opposed to bulk yield stress which is known to vary significantly on annealing. 相似文献
