批评性语篇分析应用摭谈——以解读希拉里竞选演说为例

批评性语篇分析主要研究语言、权力和意识形态之间的关系。作为一种“工具语言学”,批评性语篇分析着重分析符号及其交流意义之间的关系,以揭示语篇中含而不露的意识形态意义。借助批评性语篇分析这一重要的语言工具,分析希拉里的竞选演说,有助于我们更好地把握美国政治人物竞选过程中的语言策略。

The modality effect tested in children in a user‐paced multimedia environment

The modality learning effect proposes that learning is enhanced when information is presented in both the visual and the auditory domains (e.g. pictures and spoken information) compared with presenting information solely in the visual channel (e.g. pictures and written text). Most of the evidence for this effect comes from adults in a laboratory setting. Therefore, we tested the modality effect with 80 children in the highest grade of elementary school in a naturalistic setting. In a between‐subjects design, the children either saw representational pictures with speech or representational pictures with text. Retention and transfer knowledge was tested at three moments: immediately after the intervention, one day after and after one week. The present study did not find any evidence for a modality effect in children when the lesson was learner‐paced. Instead, we found a reversed modality effect directly after the intervention for retention. A reversed modality effect was also found for the transfer questions one day later. This effect was robust, even when controlling for individual differences.     

Compatibility of motion facilitates visuomotor synchronization.

Prior research indicates that synchronized tapping performance is very poor with flashing visual stimuli compared with auditory stimuli. Three finger-tapping experiments compared flashing visual metronomes with visual metronomes containing a spatial component, either compatible, incompatible, or orthogonal to the tapping action. In Experiment 1, synchronization success rates increased dramatically for spatiotemporal sequences of both geometric and biological forms over flashing sequences. In Experiment 2, synchronization performance was best when target sequences and movements were directionally compatible (i.e., simultaneously down), followed by orthogonal stimuli, and was poorest for incompatible moving stimuli and flashing stimuli. In Experiment 3, synchronization performance was best with auditory sequences, followed by compatible moving stimuli, and was worst for flashing and fading stimuli. Results indicate that visuomotor synchronization improves dramatically with compatible spatial information. However, an auditory advantage in sensorimotor synchronization persists.

盾构掘进中刀盘振动分析

针对不均匀地层中盾构施工引起的刀盘振动问题,建立刀盘有限元计算模型,并基于振动结构模态分析理论,分析盾构刀盘的模态特性,得到刀盘振型分析的结果同盾构掘进中出现的实际问题现象相一致。另外,以模态分析的结果为依据,分别从刀盘底座直径及柔度变化的角度分析对刀盘模态的影响,提出增大刀盘模态的方法及对刀盘结构设计的建议,从而可避免由于刀盘所受冲击与振动所致的联接螺栓松动及联接部件裂纹。此设计建议可应用于其它盾构刀盘的结构设计中,具有较大的工程实用价值。     

Modality options for renal replacement therapy: the integrated care concept revisited

As the End-stage renal disease population continues to grow, innovative strategies that optimize patient outcomes while capitalizing on the relative strengths of the existing modalities must be sought. Renal transplantation remains the preferred form of renal replacement therapy, but given the limited supply of donor organs, dialytic therapies will continue to constitute a large part of the modality mix. Matching patients to the most suitable modalities requires that a number of factors be considered. These include the patient's autonomy, medical and social factors, system-related issues, patient outcomes, and finances. While peritoneal dialysis and hemodialysis (HD) have traditionally been viewed as competing modalities, we propose that they, along with home and frequent HD regimens, may be used in a complementary manner, which is based on current evidence, and may provide optimal outcomes while containing treatment costs. In this review, we attempt to synthesize the current literature describing the various issues that affect modality selection, and offer an approach to achieving a balance between these many competing factors.

标准的起源和发展的形式(上)

本文对人类历史上标准的起源和标准产生形式进行了深入的讨论,建立了人类历史上具有里程碑意义的标准形成关系。这些重要的标准形式为动作行为标准、语言标准、工具标准、文字标准、度量衡标准、文件标准等。本文深入讨论了每类标准产生的背景原因、形成的形式、特点、作用等。论证得出标准的起源形式不是以往所说的语言形式的标准,而是动作行为形式的标准,研究将标准的起源结论提前了两个历史阶段。本文还分析了标准发展的综合关系。
