高职院校“双师型”师资培养策略

在国家大力发展高等职业教育政策的引导下,我国高等职业教育事业得到了迅速发展。在高职教育发展过程中,师资问题已成为制约高职教育快速、健康发展的“瓶颈’,最突出表现为“双师型”师资的缺乏。面对高职院校“双师型”师资队伍建设的主要困难,有必要加强“双师型”师资队伍建设,拓宽“双师型”师资队伍的培养途径。     

从《圆圆曲》与《长恨歌》看梅村体与长庆体之区别

《圆圆曲》和《长恨歌》分别是梅村体和长庆体的代表作品。在创作上，《圆圆曲》受到《长恨歌》的很大影响，但是两诗在作者感情的抒发、表现手法、用典、叙述方式与叙述视角等方面有很明显的区别。

Analysis of Covariance and Randomized Block Design with Heterogeneous Slopes

The authors compared the Type I error rate and the power to detect differences in slopes and additive treatment effects of analysis of covariance (ANCOVA) and randomized block (RB) designs with a Monte Carlo simulation. For testing differences in slopes, 3 methods were compared: the test of slopes from ANCOVA, the omnibus Block × Treatment interaction, and the linear component of the Block × Treatment interaction of RB. In the test for adjusted means, 2 variations of both ANCOVA and RB were used. The power of the omnibus test of the interaction decreased dramatically as the number of blocks used increased and was always considerably smaller than the specific test of differences in slopes found in ANCOVA. Tests for means when there were concomitant differences in slopes showed that only ANCOVA uniformly controlled Type I error under all configurations of design variables. The most powerful option in almost all simulations for tests of both slopes and means was ANCOVA.     

成就动机对自信与A型行为关系的解释作用

为了检验成就动机能否解释自信与Type A的相关，确定自信与Type A相关的性质，采用总体自信问卷、中国人A型量表和成就动机量表为工具，对自信与Type A的关系进行了探讨。结果发现，自信确实与Type A存在先前研究发现的正相关，但与其敌意因子呈负相关；控制成就动机成分后，自信与Type A的正相关关系消失，而与敌意因子的负相关关系不受影响。自信与Type A的关系体现了自信的成就动机功能，是积极的而不是消极的。     

WebCT and Its Growth as a Type II Application

Abstract

Maddux, Johnson, and Willis mentioned in 1992 some “yet-to-be-developed types” that “have the potential to be Type II software if they are used in such a way that the user is given the ability to learn in new and better ways.” The authors of this paper will frame the discussion of learning management systems (LMS) around the concept of Type I and Type II applications of computers in education. We suggest that with the new trends of interoperability within WebCT, more researchers will accept WebCT as a potential Type II application. As more interactive learning objects are developed and shared on the WebCT format, it should be easier for instructors to create and teach courses that reflect the value systems expressed in the concept of Type II learning.

Influence of Type D personality on quality of life in university students: The mediating effect of health-promoting behavior and subjective health status

This study aimed to test a hypothetical path model estimating the influence of Type D personality on health-promoting behaviors (HPB), subjective health status, and quality of life (QoL) in university students, and to verify the mediating effects of HPB and subjective health status between Type D personality and QoL. A structural equation model involving 380 university students was used. Data were collected between November and December 2018 via structured questionnaires and analyzed using SPSS 25.0 and Amos 23.0. The model's fit indices were adequate. Type D personality had a direct effect on QoL and an indirect effect on QoL via HPB and subjective health status. Type D personality, HPB, and subjective health status explained 67.6% of the total variance in QoL. Intervention programs that consider Type D personality, HPB, and subjective health status may be useful to improve university students' QoL.     

论战国问对体文献起源于“访问”制度

战国问对体文献有众多独特的言说方式,其中最为本质的特征应该是主动性咨询、请教行为。流行于整个春秋时期的＂访问＂制度,在言说方式上与战国问对体文献有着众多本质特征的一致性。具体考察＂访问＂行为的文本事例,可以断定问对体文献应直接来源于＂访问＂制度。在从＂访问＂行为走向诸子问对体文献的过程中,孔子及稍后的七十子著述起着重要的桥梁,对战国问对体散文而言,他们的努力无疑具有开创性质。

Why We (Usually) Don't Have to Worry About Multiple Comparisons

Abstract

Applied researchers often find themselves making statistical inferences in settings that would seem to require multiple comparisons adjustments. We challenge the Type I error paradigm that underlies these corrections. Moreover we posit that the problem of multiple comparisons can disappear entirely when viewed from a hierarchical Bayesian perspective. We propose building multilevel models in the settings where multiple comparisons arise. Multilevel models perform partial pooling (shifting estimates toward each other), whereas classical procedures typically keep the centers of intervals stationary, adjusting for multiple comparisons by making the intervals wider (or, equivalently, adjusting the p values corresponding to intervals of fixed width). Thus, multilevel models address the multiple comparisons problem and also yield more efficient estimates, especially in settings with low group-level variation, which is where multiple comparisons are a particular concern.

Evaluating Model Fit With Ordered Categorical Data Within a Measurement Invariance Framework: A Comparison of Estimators

A paucity of research has compared estimation methods within a measurement invariance (MI) framework and determined if research conclusions using normal-theory maximum likelihood (ML) generalizes to the robust ML (MLR) and weighted least squares means and variance adjusted (WLSMV) estimators. Using ordered categorical data, this simulation study aimed to address these queries by investigating 342 conditions. When testing for metric and scalar invariance, Δχ² results revealed that Type I error rates varied across estimators (ML, MLR, and WLSMV) with symmetric and asymmetric data. The Δχ² power varied substantially based on the estimator selected, type of noninvariant indicator, number of noninvariant indicators, and sample size. Although some the changes in approximate fit indexes (ΔAFI) are relatively sample size independent, researchers who use the ΔAFI with WLSMV should use caution, as these statistics do not perform well with misspecified models. As a supplemental analysis, our results evaluate and suggest cutoff values based on previous research.     

More Powerful Tests of Simple Interaction Contrasts in the Two-Way Factorial Design

For the two-way factorial design in analysis of variance, the current article explicates and compares three methods for controlling the Type I error rate for all possible simple interaction contrasts following a statistically significant interaction, including a proposed modification to the Bonferroni procedure that increases the power of statistical tests for deconstructing interaction effects when they are of primary substantive interest. Results indicate the general superiority of the modified Bonferroni procedure over Scheffé and Roy-type procedures, where the Bonferroni and Scheffé procedures have been modified to accommodate the logical implications of a false omnibus interaction null hypothesis. An applied example is provided and considerations for applied researchers are offered.     

高职院校“双师型”教师终身发展的制度设计
