基于修正的沃斯价值比率模型的开放式基金绩效评价研究 总被引：1，自引：0，他引：1

资产收益率解析 总被引：1，自引：0，他引：1
王春香 《辽宁师范大学学报(社会科学版)》2005,28(3):25-27
资产收益率是综合反映公司业绩的重要指标。将资产收益率分解出多个因子,并与同行公司比较各因子的水平,可以发现改善业绩的途径。这里尝试对资产收益率做进一步的探讨,建立了资产收益率与产品寿命周期、价值链等现代战略思想之间的逻辑关系．并设计了由资产收益率及其因子得出公司战略导向和手段的基本思路。 相似文献

影响因子是一个相对量,它是评价期刊的重要参考指标,可公平地评价和处理大、小期刊由于发文量不同所带来的偏差,期刊影响因子值越大,则它的影响力和学术作用也越大;由于我院学报受学院整体学术水平和社会影响力不高,教科研成果及学术论文水平不尽人意等因素的影响,学报被引频次、影响因子值很低;指出通过获得学院相关政策的扶持,采取办特色栏目、约专家稿、提高编辑人员业务素质等方式,提高学报质量,增加学报影响因子值。 相似文献

We examine the power associated with the test of factor mean differences when the assumption of factorial invariance is violated. Utilizing the Wald test for obtaining power, issues of model size, sample size, and total versus partial noninvariance are considered along with variation of actual factor mean differences. Results of a population study show that power is profoundly affected by true factor mean differences but is relatively unaffected by the degree of factor loading noninvariance. Inequality of sample size has a profound effect on power probabilities with power decreasing as sample sizes become increasingly disparate. Sample size variations operate such that power is uniformly lower when the group with the smaller generalized variance is associated with the smaller sample size. An increase in the number of variables yields uniformly larger power probabilities. No substantial differences are found between total and partial noninvariance. Results are related to work in the area of robustness of Hotelling's T 2 statistic and discussed in terms of asymptotic covariability of factor means and factor loadings. Implications for practice are considered. 相似文献

用"导为主"取代"为主导"--关于教师在主体性教育教学中作用定位的思考 总被引：2，自引：0，他引：2
陈仁保 《湖南师范大学教育科学学报》2003,2(4):54-57
从内国外因辨证关系上看，学生是发展的主体，是教育教学过程中惟一的起主导作用的内在因素。教育者如果总认为自己也是教育的主体，起主导作用，其后果是教师取代学习者的主体地位，干扰其主导作用的发挥。因此，教师的主要作用应定位在对学生这个惟一主体的启发和引导上。 相似文献

The Norwegian government recommends a systematic language assessment of all four-year-olds as part of the general health surveillance program for the purpose of identifying children at risk of language delay. This study aimed to investigate the construct validity of the recommended language screening tool called LANGUAGE4 [SPRÅK4] by first examining the dimensionality of the underlying construct of the tool, after which the concurrent convergent validity was established by regressing an external language factor, defined by four standardized language tests, on a single higher-order factor. The findings provide support for a higher-order model with one general language factor, suggesting that a large amount of the variance in LANGUAGE4 is attributable to a single common factor at the second-order level. Furthermore, this single factor explained a considerable amount of the variance in the external language factor. Our findings are interpreted as support for satisfactory construct validity of LANGUAGE4. 相似文献

Student evaluation of instruction and instructor performance in higher education are being accorded an increasingly prominent role in decisions concerned with faculty promotion and tenure, as well as with advisement on teaching strategies. In this context a number of factor analyses have been imposed upon student rating-instruments in order to facilitate meaningful interpretation of student judgments. The present paper reports the resul ts of a factor analysis of the rating scales used by graduate students enrolled in counselor education programs at Western Michigan University to evaluate perceived quality of instruction. A principal components factor analysis yielded three interpretable factors that were labeled Responsiveness-Rapport, Evaluation Process, and Instructional Merit. Implications of the factor structure for counselor educators are discussed. 相似文献

We present a test for cluster bias, which can be used to detect violations of measurement invariance across clusters in 2-level data. We show how measurement invariance assumptions across clusters imply measurement invariance across levels in a 2-level factor model. Cluster bias is investigated by testing whether the within-level factor loadings are equal to the between-level factor loadings, and whether the between-level residual variances are zero. The test is illustrated with an example from school research. In a simulation study, we show that the cluster bias test has sufficient power, and the proportions of false positives are close to the chosen levels of significance. 相似文献

The purpose of the present study was to test the factor structure of the McCarthy Scales of Children's Abilities in preschool children. Seventy-two boys and 69 girls between 4 and 5 years of age were tested. A factor analysis was carried out by means of the principal components method with varimax rotation. The existence of the Verbal factor and of the Perceptual-Performance factor was confirmed. The Quantitative and Memory factors appear undifferentiated. As far as the subtests which make up the Motor scale are concerned, they do not constitute a single factor. The significance of these findings is discussed. 相似文献
