过敏性紫癜是儿童常见的免疫系统疾病。西医治疗过敏性紫癜已形成常规模式,并有一定疗效,但也有一定局限性。本病易反复,易损伤肾脏,严重时可导致紫癜性肾炎。本文拟研究中西医结合方法治疗过敏性紫癜及预防肾脏损伤的临床效果。研究表明,中西医结合治疗该病存在一定优势,能有效治疗过敏性紫癜,并降低肾脏损害及紫癜性肾炎的发生率。但应看到本研究结论主要是通过临床经验取得,样本量小,未进行远期随访,缺乏系统深层次实验室论证,还有待进一步研究。 相似文献

This research examined the impact of dialectical thinking (DT) on perceived training outcomes in commercial leadership training using a quasi‐experimental design. Study 1 found that high‐DT individuals had better perceived on‐site training outcomes when compared with individuals with low DTs, regardless of training methods. But there was no significant difference between low and high DTs on subsequent behavioral improvements. It was also found that self‐reported training outcomes were consistent with others' observation. To further validate the on‐site effect of DT, we introduced a cognitive style manipulation prior to training to increase DT levels among trainees in Study 2. Individuals following the cognitive style manipulation reported significantly better perceived training outcomes. The implications of this research for field training are discussed. 相似文献

Teacher commitment: a comparative study of Malaysian ethnic groups in three types of primary schools
Commitment is a complex attitude that is potentially influenced by the nature of the groups and is contingent on the context in which an individual functions. Thus, different sociocultural environments will prescribe different imperatives for individuals’ or groups’ attitudes toward their work, particularly teachers’ commitment in a multi-ethnic educational setting. However, previous teacher commitment studies have predominantly been applied to single-sample studies in a multiracial Malaysian context. Therefore, this study attempts to compare the teacher commitment levels and the four dimensions of teacher commitment across Malay, Chinese and Indian teachers who are the dominant ethnicities in three different types of Malaysian primary schools. Questionnaires were administered to 1,154 primary school teachers in Penang, and the obtained data were analysed using AMOS 20.0 and SPSS 20.0. The findings revealed nonsignificant differences for commitment to school, commitment to students, commitment to teaching and commitment to profession for any pair of ethnic groups. Limitations and suggestions for future studies are discussed. 相似文献

This study examined the impact of relationship distress in a sample of 637 African American young adults from the Family and Community Health Study. Using data from privately collected, in-depth interviews, we assessed how distress in nonmarital romantic partnerships and best friendships influence anger. While social support researchers have examined the stress buffering influence of supportive relationships, we utilized the principle of negative potency to test the stress amplification effect of relationship distress through an assessment of stressful life events and racial discrimination. Our analysis showed that distress in relationships was associated with anger, while the presence of these relationships was not. Support for the stress amplification hypothesis was found as men and women who experience intense racial discrimination coupled with a more hostile best friend had elevated levels of anger. Gender differences were also evident and discussed. 相似文献

Despite growing interest in early intervention, there are few measures available to monitor the progress of early academic skills in preschoolers. The Early Arithmetic, Reading, and Learning Indicators (EARLI; DiPerna, Morgan, & Lei, 2007) were developed as brief assessments of critical early literacy and numeracy skills. The purpose of the current study was to examine the factor structure of the EARLI probes via confirmatory factor analysis (CFA) in a sample of Head Start preschoolers (N = 289). A two-factor model with correlated error terms and a bifactor model provided comparable fit to the data, although there were some structural problems with the latter model. The utility of the bifactor model for explaining the structure of early academic skills as well as the utility of the EARLI probes as measures of literacy and numeracy skills in preschool are discussed. 相似文献

Inferences about moral character may often drive outrage over symbolic acts of racial bigotry. Study 1 demonstrates a theoretically predicted dissociation between moral evaluations of an act and the person who carries out the act. Although Americans regarded the private use of a racial slur as a less blameworthy act than physical assault, use of a slur was perceived as a clearer indicator of poor moral character. Study 2 highlights the dynamic interplay between moral judgments of acts and persons, demonstrating that first making person judgments can bias subsequent act judgments. Privately defacing a picture of Martin Luther King, Jr. led to greater moral condemnation of the agent than of the act itself only when the behavior was evaluated first. When Americans first made character judgments, symbolically defacing a picture of the civil rights leader was significantly more likely to be perceived as an immoral act. These studies support a person‐centered account of outrage over bigotry and demonstrate that moral evaluations of acts and persons converge and diverge under theoretically meaningful circumstances.

The present study compared single and dual adaptation to visuomotor rotations in different cueing conditions. Participants adapted either to a constant rotation or to opposing rotations (dual adaptation) applied in an alternating order. In Experiment 1, visual and corresponding postural cues were provided to indicate different rotation directions. In Experiment 2, either a visual or a postural cue was available. In all cueing conditions, substantial dual adaptation was observed, although it was attenuated in comparison to single adaptation. Analysis of switching costs determined as the performance difference between the last trial before and the first trial after the change of rotation direction suggested substantial advantage of the visual cue compared to the postural cue, which was in line with previous findings demonstrating the dominance of visual sense in movement representation and control. 相似文献

选择题中的作答选项能提供额外诊断信息, 为充分利用选项信息, 研究提出认知诊断计算机自适应测验(CD-CAT)中两种处理选择题选项信息的非参数选题策略和变长终止规则。模拟研究的结果发现:(1)定长条件下两种非参数选题策略的分类准确性整体要高于参数选题策略; (2)两种非参数选题策略较参数选题策略具有更加均衡的题库使用情况; (3)非参数选题策略在两种新的变长终止规则下具有更高的分类准确率; (4)两种非参数选题策略均适用于选择题CD-CAT情境, 使用者可任选其一进行测验分析。 相似文献
