固有无序蛋白是一类具有柔性结构的蛋白质,许多情况下通过与其它物质相互作用形成稳定结构来发挥重要生物功能.本文分别利用基于序列特征和结构特征的蛋白质结合位点预测程序对固有无序蛋白有序区和无序区与核酸分子的结合位点进行了预测分析.结果发现,基于结构特征的结合位点预测方法整体上要优于基于序列特征的预测方法,表明无序区尽管缺少稳定空间结构,结构特征依然在固有无序蛋白结合位点中发挥了重要作用.因此,可以为今后固有无序蛋白序列特征及结构特征的提取提供可靠依据.  相似文献

This study measured unilateral, tachistoscopic naming reaction times of normal and reading disordered children to objects representing two levels of picture vocabulary age. Results of an ANCOVA procedure on the latency data showed main effects for group and stimuli, but not visual field. The latency results suggested parallel, central picture naming operations for each group, with the reading disordered children evidencing significantly longer naming reaction times to each level of stimuli. Arc Sine transformed error data were submitted to an analysis of co-variance procedure and showed a significant stimuli x group interaction. Post hoc tests showed accelerated error rates following right hemispheric stimulation, suggesting anomalous interhemispheric transfer of visual images in the present group of reading disordered children. In addition, left hemispheric stimulations produced significantly more naming errors for the reading disordered subjects as compared to the normal children. Such findings may suggest that a group of higher-ordered processing operations may accompany reading disorders.  相似文献

INTRODUCTION Williamson (1975), Jensen and Meckling (1976),and Fama and Jensen (1983) held that incentive con-tracts and organizational form are closely tied, andthat organizational form is an optimal response toagency problem. Stiglitz (1986) argued that the in-centive structure of an organization ought to respondquickly to changes in the economic environment inorder to provide appropriate managerial incentives.Corporate divestment is certainly one of the mostdrastic changes in th…  相似文献

The purpose of this article was to evaluate theories that (1) weight-related abuse (WRA) plays a unique role in the development of disordered eating, above and beyond general childhood verbal abuse and weight-related teasing, and (2) the perceived emotional impact of WRA mediates the relationship between WRA and current disordered eating. Self-report questionnaires on childhood trauma, weight-related teasing, WRA, and current eating behaviors were administered to a total of 383 undergraduate students. In initial regressions, WRA significantly predicted binge eating, emotional eating, night eating, and unhealthy weight control. WRA continued to significantly predict all 4 forms of disordered eating following the introduction of measures of weight-related teasing and childhood verbal abuse into the regression. Latent variable analysis confirmed that perceived emotional impact of WRA mediated the relationship between WRA and disordered eating, and tests for indirect effects yielded a significant indirect effect of WRA on disordered eating through perceived emotional impact. In sum, WRA is a unique construct and the content of childhood or adolescent maltreatment is important in determining eventual psychopathology outcomes. These findings support the necessity of incorporating information on developmental history and cognitive factors into assessment and treatment of individuals with disordered eating.  相似文献

The purpose of this study was to determine if there is a difference between the self-perceptions of the behaviorally disordered child and the perceptions of the child by his/her teacher and mother. A related purpose was to determine if there are specific areas (factors) with greater discrepancies. Normal and behaviorally disordered children, matched by grade and sex, were evaluated using the Piers-Harris Children's Self-concept Scale. There were significantly lower scores given by the three evaluator groups for the behaviorally disordered. The teachers evaluated the behaviorally disordered children significantly lower than did the other evaluators. For the normal children, there were no significant differences between the three evaluator groups. The pattern of evaluations was the same for all factors. The only exception in each of these findings was Factor III—Physical Appearance and Attributes—in which both normal and behaviorally disordered children evaluated themselves lower than did their teachers and mothers. Implications of these findings for school personnel are discussed.  相似文献

College students may be misdiagnosed as personality disordered when in fact their problems are better explained by their upbringing. Growing up with a personality disordered parent may cause them to initially present with what appear to be personality disordered traits due to issues such as not learning adequate coping skills. Accurate diagnosis is important because it affects current treatment and referrals for longer-term treatment.  相似文献

Abstract

The article examines the use of information and communication technology to enhance the educational achievement of a group of students evidencing a variety of EBD in a mainstream school setting. It is believed that ICT will have just as important a part to play in the education of students with EBD as it will with other sensory or physical special educational needs. The article examines within-child factors which make a cognitive-behavioural approach potentially powerful. It suggests that ICT can enhance the educational experience of EBD pupils if careful attention is paid to the creation of a therapeutic teaching environment and the interaction of the student/curriculum and teacher/student interfaces. The article discusses the implementation of an integrated learning system in an inner London comprehensive school and its effects on those pupils presenting with emotionally disordered learning difficulties.  相似文献

固有无序蛋白质是一类在生理状态下没有固定三维结构,却可以发挥正常生物学功能的蛋白质.对这类蛋白质系统深入的研究丰富了人们对蛋白质生物学功能的认识.固有无序蛋白质预测经过十多年发展,已经成为发现新固有无序蛋白质的重要工具;而分子动力学模拟则为我们从微观上研究固有无序蛋白构象变化过程、分析固有无序蛋白与其他分子的相互作用,以及揭示这类蛋白质的特征等发挥了不可替代的作用.  相似文献

The fracture behavior of disordered and ordered Ni4Mo alloy was investigated by tensile tests in hydrogen gas or during hydrogen charging. The results show that the ductility of the disordered alloy decreased slightly with the hydrogen pressure increasing, while that of the ordered alloy decreased rapidly with the hydrogen pressure increasing. However, the ductility of both disordered and ordered alloys reduced similarly seriously with the charging current density increasing. Therefore, the mechanism of order-induced embrittlement of Ni4 Mo alloy in hydrogen gas is supposed to be that atomic order accelerates the kinetics of the catalytic reaction for the dissociation of molecular H2 into atomic H.  相似文献

1IntroductionNickel-based alloys containing 20 -30 wt % Mo isknown to be essential for corrosion resistance in re-ducing media[1],especially for resistance to HCl at alltemperatures and concentrations[2]. However , uponexposure to elevated temperatures in the range of600 -800 ℃,these alloys suffer an al most completeloss of roomtemperature ductility as a result of long-range ordering (LRO) to Ni4Mo .It is considered thatthe loss of ductility mainly results from the environ-mental embrittle…  相似文献
