课堂教学中差异性教学探微

差异性教学主要是根据学生的个别差异而进行了教学，在教学中，可以通过鉴别学生的差异，利用教学的分层和各种的教学形式来体现或达到差异性教学。     

论可能世界理论中的两个问题

在现代逻辑研究中,可能世界语义学不仅揭示了模态逻辑公理系统的直观背景,而且提供了强有力的语义工具,使模态逻辑的研究进入了一个崭新的阶段。但在可能世界语义学的研究中,也遇到了许多哲学上的难题。因此,对有关可能世界的定义与跨界识别问题进行分析、探讨确实很有必要。     

我国BOT融资项目中的风险分析

作为项目融资的后起之秀，BOT被国际金融界称为极具潜力的项目融资模式。BOT融资项目是一个比较复杂的过程，由于项目完成周期长，外部经济环境和内部操作中的意外变动都会给项目融资带来巨大的风险，因此对其进行风险分析，建立风险防范体系具有重要的意义。     

Genetic programming-based chaotic time series modeling

INTRODUCTION Chaos is based on the principle that simpledeterministic laws can exhibit complex externalbehavior (Hegger and Kantz, 2000); although it isquite difficult to reveal such simple laws from thesystem’s external behavior only. This is mainly dueto the dissipation and sensitivity to initial condi-tions (SIC) properties of the chaotic systems (Weiet al., 2002). Linear system theory has developedfor many years, but has proved to be incapable ofsufficiently modeling the chaot…

Scale for assessing undergraduates’ interdisciplinary competences related to the smart living industry

In this study, a scale was constructed to aid college educators in developing interdisciplinary courses for smart living industry–related talent cultivation. The scale, named the Undergraduate Student Interdisciplinary Competences for the Smart Living Industry (USIC_SLI) scale, was developed on the basis of a literature review and a two-phase expert survey. A pilot test was performed, and exploratory and confirmatory factor analyses were conducted to understand the scale’s reliability and validity. The final version of the scale comprises five subscales (i.e. communication, reflection, practice, technology values, and entrepreneurship) and 25 items. The Cronbach’s α of the scale was 0.92, and that of the subscales ranged from 0.82 to 0.89. Structural equation modelling revealed that the theoretical model and observation data of the scale were compatible, and the results indicated that the scale had appropriate validity and reliability.     

摩擦补偿下基于关节力矩的笛卡尔阻抗控制

为了研究基于关节力矩信息的笛卡尔阻抗控制策略及摩擦补偿的影响,利用关节本身具有的传感器,进行了辨识谐波驱动摩擦参数、摩擦补偿和笛卡尔阻抗控制的实验研究．与传统的基于机器人末端力／力矩信息的笛卡尔阻抗控制方案不同,考虑了5种基于关节力矩的笛卡尔阻抗控制方案,包括笛卡尔空间／关节空间基于力的、笛卡尔空间／关节空间基于位置的方案和刚度控制．其中,前4种方案分别在有／无摩擦补偿的条件下进行了相应的实验验证．实验比较结果表明：对于基于关节力矩信息来实现笛卡尔阻抗控制的机器人,基于力的阻抗控制策略比基于位置的策略更适合,并且摩擦对这类笛卡尔阻抗控制的稳定性有积极影响．     

Structural invariance in the associations of naming speed,phonological awareness,and verbal reasoning in good and poor readers: A test of the double deficit hypothesis

The associations of multiple measures of speeded naming, phonological awareness, and verbal intelligence with word reading were examined in 51 poor readers and 74 good readers in third and fourth grade. Structural equation modeling was used to determine the extent to which these two groups exhibited structurally invariant patterns of associations among the constructs. Results revealed that for poor readers, both speeded naming and phonological awarencess were significantly associated with word reading, but verbal intelligence had no association with it. In contrast, for good readers, phonological awareness and verbal intelligence were significantly associated with word reading, but naming speed was not. Findings are discussed in light of the double deficit hypothesis.
