Research findings regarding general self-concept, academic self-concept, and self-awareness in students with learning disabilities have varied, and results are still inconclusive regarding the consistency between students' and teachers' judgments of academic performance. The current study focuses on students' and teachers perceptions of the students' strategy use and performance in nine different academic and organizational domains. Six hundred sixty-three students and their 57 teachers were involved in the study. Findings indicated that the students with learning disabilities considered themselves appropriately strategic and competent in the five domains of reading, writing, spelling, math, and organization. These students also rated their academic performance and organization as average to above-average in seven of nine domains, with the exception of checking and planning their work. Nevertheless, the self-ratings of the students with learning disabilities were still significantly lower than the self-ratings of average achievers in virtually all domains. The second major set of findings revealed a sharp discrepancy between the self-assessments of the students with learning disabilities and their teachers' judgments. Teachers rated the students with learning disabilities as weak in their strategy use and below-average in their performance in all nine academic and organizational domains. Finally, gender differences were not evident in eight of the nine domains. These results have added to the increasing body of literature indicating that students with learning disabilities frequently perceive themselves as capable and effective and often rate themselves as academically stronger than their teachers judge them to be. 相似文献

The energy spectra of the secondary ion emission (SIE) for transition metals of the fourth period are calculated under the assumption that SIE is caused by the joint action of electron-exchange and kinetic ion emission (KIE) mechanisms. Some improvement of the KIE theory is carried out for the cases of high (of the order of tens of keV) and low (less than 2 keV) energies EO of bombarding ions. It is found that the KIE plays an essential role in SIE, starting from the EO value of the order of tens of keV. It is shown that the KIE energy spectra (1) are broader than the sputtering energy spectra by an order of magnitude, (2) differ essentially in both cases indicated, (3) show a peak (at high EO in accordance with an experiment) or a break (at low EO) near to the secondary ion energy corresponding to the KIE threshold. 相似文献

The combined anterolateral osteoplastic fixation of the spine was carried out on 17 cases out of 73 operated upon for pathological spinal changes of various etiology. The tibial crest rigid homograft and the rib autograft on vasoneuromuscular feeding pedicle were used. Such a combination of bone grafts possessing different mechanic and osteogenic properties permitted to obtain a reliable fixation of the spine for all the period necessary for anatomic and functional reconstruction of the grafts. 相似文献

In a 4 month study, a group of 16 patients with stable renal graft function receiving triple immunosuppressive therapy including cyclosporin A (Cy A) were investigated for the levels of calcium, magnesium and zinc in erythrocytes. The patients were randomized to be converted to the new microemulsion formulation (Sandimmun Neoral) in a 1:1 fashion (n = 8) or to continue with the classical formulation (Sandimmun) (n = 8). The concentrations of creatinine, phosphate, alkaline phosphatase activity, calcium, magnesium and zinc were measured twice a month in blood plasma. The concentration of calcium, magnesium and zinc in erythrocytes was also measured. The concentration of magnesium in blood plasma and erythrocytes during the study showed no deviation from normal values. The level of zinc in erythrocytes was almost twice as high as in normal healthy controls and was not dependent on Cy A formulation. Calcium content in erythrocytes of patients receiving Sandimmun was 27.6% higher than in healthy persons. Conversion of the patients to Sandimmun Neoral normalized the calcium concentration in erythrocytes and caused a transient increase of calcium levels in blood plasma. 相似文献

In this paper, characterization is given of clinical and biochemical features of VH B course against the background of narcomania. Recordable in such patient populations are high percentage of delta hepatitis (14.2%), unusual severity of the intoxication syndrome, protracted course with exacerbations (12.2%) and recurrences (8%), outcome being a chronic hepatitis (14.2%), slower normalization of biochemical indicators, persistently low ratio of AIAT activity in diluted and whole blood sera. The persistence of viral markers in drug addicts discharged from the hospital (68%) is fraught with danger of spreading viral hepatitis of prophylactic measures are not strictly observed. 相似文献
