The authors examined whether the influence of reading purpose on reported use of text-processing strategies was moderated by students' prior knowledge about the topic of the text. Using multiple regression analyses with interaction terms, they found that the effect of reading purpose on reported use of memorization and elaboration strategies depended on students' level of topic knowledge. For participants who read for the purpose of discussing text content, reported use of memorization and elaboration was positively related to topic knowledge, whereas no relation between reported use of such strategies and topic knowledge was found for participants who read for the purposes of test taking or summary writing. This suggests that students' flexible use of text-processing strategies may depend on their topic knowledge. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The work-hardening behavior of a range of aluminum-magnesium alloys, from 0.5 to 4.55 wt pct Mg, is followed up to large strains
using compression testing and cold rolling. At large strains, stage IV, an unexpectedly low work-hardening rate of high-Mg
alloys is observed, and the work-hardening rate in stage IV is almost unaffected by the Mg content. A model for work hardening
is applied and discussed in relation to the experimental observations. Based on microstructural observations of the cold-rolled
materials, the low work-hardening rate of high-Mg alloys is ascribed to a different storage pattern of dislocations caused
by an increased amount of shear bands and a higher dislocation density inside subgrains. 相似文献

The article presents information gained from a survey among Norwegian hospitals in March 1997 concerning their treatment of infections with Helicobacter pylori. Altogether 52 hospitals answered the questionnaire. A combination of proton pump inhibitors, metronidazole and clarithromycin was used by 59% as first choice and urea quick test (94%) and urea breath test (42%) as the primary diagnostic procedures, whereas serology was in little use (17%). Besides ordinary ulcer disease, indications for treatment were: ulcer induced by non-steroid anti-inflammatory drugs (79%), gastrooesophageal reflux (37%), non-ulcer dyspepsia (14%) and cancer prophylaxis (14%). The gastro group at the Department of Pharmacotherapeutics at the University of Oslo invited specialists from all health regions to discuss indications for treatment of H pylori, the diagnosis and the role of general practitioners. The extensive use of clarithromycin might be doubtful due to development of resistance. Indications for treatment of H pylori other than ulcer disease and mucosa associated lymphoid tissue lymphoma are still uncertain. Uncritical use of serological tests in primary care should be discouraged. At present there is no uniform strategy for the diagnosis and treatment of H pylori infection, and a coordinated strategy between general practitioners and specialists is needed. 相似文献

Reinforced 6 autistic, 5 retarded, and 5 normal children for responding to a complex stimulus involving the simultaneous presentation of auditory, visual, and tactile cues. After discrimination was established, elements of the complex were presented separately to assess which aspects of the complex stimulus had acquired control over the S's behavior. It was found that (a) the autistics responded primarily to only 1 of the cues, normals to all 3 cues, and retardates to 2 cues; and (b) conditions could be arranged such that a cue which had remained nonfunctional when presented in association with other cues could be established as functional when trained separately. Data fail to support theories that any 1 sense modality is impaired in autistic children. When presented with a stimulus complex, autistic Ss' attention was overselective. Findings are related to the literature on selective attention. Since much learning involves contiguous or near-contiguous pairing of 2 or more stimuli, failure to respond to 1 of the stimuli may be an important factor in the development of autism. (27 ref.)

The treatment of choice for transsexualism and transvestism is early identification and prevention, but the treatment of children with gender disturbances raises potential risks associated with the arbitrary nature of some sex-role distinctions in our culture. Potential risks are weighed against the potential benefits in the treatment of gender-disturbed boys. The psychological profession should promote greater social tolerance for individuals with deviant sex roles and individual tolerance in children for androgyny in their own sex roles.

Objective: Transference interpretation is considered as a core active ingredient in dynamic psychotherapy. In common clinical theory, it is maintained that more mature relationships, as well as a strong therapeutic alliance, may be prerequisites for successful transference work. In this study, the interaction between quality of object relations, transference interpretation, and alliance is estimated. Method: One hundred outpatients seeking psychotherapy for depression, anxiety, and personality disorders were randomly assigned to 1 year of weekly sessions of dynamic psychotherapy with transference interpretation or to the same type and duration of treatment, but without the use of transference interpretation. Quality of Object Relations (QOR)–lifelong pattern was evaluated before treatment (P. H?glend, 1994). The Working Alliance Inventory (A. O. Horvath & L. S. Greenberg, 1989; T. J. Tracey & A. M. Kokotovic, 1989) was rated in Session 7. The primary outcome variable was the Psychodynamic Functioning Scales (P. H?glend et al., 2000), measured at pretreatment, posttreatment, and 1 year after treatment termination. Results: A significant Treatment Group × Quality of Object Relations × Alliance interaction was present, indicating that alliance had a significantly different impact on effects of transference interpretation, depending on the level of QOR. The impact of transference interpretation on psychodynamic functioning was more positive within the context of a weak therapeutic alliance for patients with low quality of object relations. For patients with more mature object relations and high alliance, the authors observed a negative effect of transference work. Conclusion: The specific effects of transference work was influenced by the interaction of object relations and alliance, but in the direct opposite direction of what is generally maintained in mainstream clinical theory.

A solid superacidic Nafion-H polymer was examined as a catalyst for isobutane/2-butene alkylation and compared with a cerium-exchanged Y zeolite. Both catalysts demonstrate initial alkylation activity with rapid decrease in alkylation selectivity. The total product distributions were found to be significantly different after three hours of reaction. Nafion-H showed less selectivity towards iso-octanes, but formed relatively more 2,2,4-trimethylpentane. The differences between the two catalysts suggest dissimilar favoured reaction mechanisms. 相似文献

A particular version of a spectral integrator has been designed. It consists of a xenon lamp whose light is dispersed into a color spectrum by dispersing prisms. Using a transmissive LCD panel controlled by a computer, certain fractions of the light in different parts of the spectrum are masked out. The remaining transmitted light is integrated and projected onto a translucent diffusing plate. A spectroradiometer that measures the generated light is also attached to the computer, thus making the spectral integrator a closed-loop system. An algorithm for generating the light of a specified spectral power distribution has been developed. The resulting measured spectra differ from the specified ones with relative rms errors in the range of 1%-20% depending on the shape of the spectral power distribution. 相似文献
