“以赛代考”的教学策略在高校健美操教学考核中的应用研究——以沈阳建筑大学为例

针对高校健美操课程传统应试教育评价模式的不足，通过运用“以赛代考”的教学策略，引导学生主动参与教学，变被动学习为主动学习，充分发挥学生的主体意识，从而提高学生的自主创新能力。     

论语篇连贯的等级性

论述了连贯是语篇的本质属性,语篇没有连贯与否的区分,只有连贯强弱之分,即语篇只存在连贯的等级性问题。并从语篇外部分析了共有知识和语域的选择以及语篇内部衔接手段的运用都是制约语篇连贯等级性的因素。

吉林省FDI影响因素的实证分析

改革开放以来,随着吉林省投资环境的不断优化,流入吉林省的FDI数量不断增多。使用因子分析与回归分析方法对吉林省FDI流入的影响因素进行实证分析,得出的结论是：影响吉林省FDI流入的综合因素在不断提高。其中,不断扩大的市场规模和较低的要素成本是影响吉林省FDI流入的重要因素,相比之下,较低的对外开放度和不稳定的能源供应阻碍了FDI的流入。     

关于上海若干要素市场发展的思考与对策

上海的要素市场是从20世纪90年代初为适应上海建设经济中心城市而发展起来的,现已初步形成了有形市场和无形市场相结合、全国市场和地方市场相结合、综合性市场与专业性市场相结合的具有相当水平软硬件设施为基础的要素市场体系,但是在要素市场建设和发展中还存在不平衡、不完善、不到位等方面的问题。本文主要分析上海若干要素市场发展的现状与特点,并提出了相应的发展对策。即：上海科技市场要按照构建完整的创新体系的要求,建设全国性的大市场;上海金融市场要按照实现国际金融中心的要求,融入国际性的金融市场体系;上海文化市场要按照统一开放竞争有序的要求,进一步发展文化创意产业;上海服务市场要按照实施服务经济战略的要求,促进长江三角洲一体化大市场的发展;上海房地产市场要按照完善住房保障体系与房地产市场体系建设的要求,在调整中发展。     

Influence in covariance structure analysis: with an application to confirmatory factor analysis

Influence functions are derived for the parameters in covariance structure analysis, where the parameters are estimated by minimizing a discrepancy function between the assumed covariance matrix and the sample covariance matrix. The case of confirmatory factor analysis is studied precisely with a numerical example. Comparing with a general procedure called one-step estimation, the proposed procedure has two advantages:1) computing cost is cheaper, 2) the property that arbitrary influence can be decomposed into a fi-nite number of components discussed by Tanaka and Castano-Tostado(1990) can be used for efficient computing and the characterization of a covariance structure model from the sensitivity perspective. A numerical comparison is made among the confirmatory factor analysis and some procedures of ex-ploratory factor analysis by using the decomposition mentioned above.     

The Secondary Traumatic Stress Scale (STSS)

SUMMARY

The Secondary Traumatic Stress Scale (STSS; Bride, Robinson, Yegidis, & Figley, 2004) is an easy to administer 17-itemself-report measure of secondary trauma. Bride et al. (2004) reported a measure of three domains of traumatic stress specifically associated with secondary exposure to trauma: intrusion, avoidance, and arousal. The STSS was reported to have high levels of internal consistency reliability and indicated evidence of convergent, discriminant, and factorial validity. The purpose of this paper is to examine the reliability and validity of the STSS with a national, random sample of mental health social workers. To assess the fit of the data to the three-factor structure proposed by Bride et al., a confirmatory factor analysis was performed on data from 275 social workers who indicated exposure to client trauma. The model fit the data adequately although high factor intercorrelations strongly suggest a unidimensional scale. Subsequent confirmatory factor analysis of a unidimensional scale and a second order factor analysis yielded similar results. Findings indicate the need for further scale validation. Challenges remain for measuring and distinctly differentiating between secondary trauma symptoms of arousal, avoidance, and intrusion. Implications and suggestions for future research are discussed.     

Case–control genome-wide joint association study using semiparametric empirical model and approximate Bayes factor

We propose a semiparametric approach for the analysis of case–control genome-wide association study. Parametric components are used to model both the conditional distribution of the case status given the covariates and the distribution of genotype counts, whereas the distribution of the covariates are modelled nonparametrically. This yields a direct and joint modelling of the case status, covariates and genotype counts, and gives a better understanding of the disease mechanism and results in more reliable conclusions. Side information, such as the disease prevalence, can be conveniently incorporated into the model by an empirical likelihood approach and leads to more efficient estimates and a powerful test in the detection of disease-associated SNPs. Profiling is used to eliminate a nuisance nonparametric component, and the resulting profile empirical likelihood estimates are shown to be consistent and asymptotically normal. For the hypothesis test on disease association, we apply the approximate Bayes factor (ABF) which is computationally simple and most desirable in genome-wide association studies where hundreds of thousands to a million genetic markers are tested. We treat the approximate Bayes factor as a hybrid Bayes factor which replaces the full data by the maximum likelihood estimates of the parameters of interest in the full model and derive it under a general setting. The deviation from Hardy–Weinberg Equilibrium (HWE) is also taken into account and the ABF for HWE using cases is shown to provide evidence of association between a disease and a genetic marker. Simulation studies and an application are further provided to illustrate the utility of the proposed methodology.     

近代上海远东国际汇兑中心的形成

综观历史上重要的国际汇兑中心的发展轨迹,虽各自所处的背景和优势不同,但一般而言,影响一个地区成为国际汇兑中心的最为主要的条件有三:经济规模、金融因素和政治环境。至20世纪二三十年代,上海正是具备了相当数量的汇兑业务量、一定数量的国际汇兑办理机构、品种齐全的汇兑业务种类、符合国际惯例的汇价体系、外汇管制的全面放开等特殊历史条件,与远东唯一的金市场、大条银市场相互套做,形成多角汇兑关系,成为远东汇兑市场之中心,在空间和功能上对伦敦、纽约等欧美国际金融中心起补充作用。上海外汇市场成为远东汇兑市场之中心,次于伦敦、纽约,而成为世界三大汇兑市场之一。
