余华小说的时间艺术

在八十年代中、后期,余华受西方现代派文学的启迪实现了时间意识的觉醒,开始了在时间艺术上一系列的探索。他通过对时间的割裂、扭曲,建造了自己的语言迷宫;用“宿命时间”组织小说,创造了新奇的形式感;通过词语的堆积,阻滞时间的流逝,创造了仿梦的艺术效果。     

Investigating the impact of violations of the “left and top means first” heuristic on response behavior and data quality

ABSTRACT

Web surveys are an established data collection mode that use written language to provide information. The written language is accompanied by visual elements, such as presentation formats and shapes. However, research has shown that visual elements influence response behavior because respondents sometimes use interpretive heuristics to make sense of the visual elements. One such heuristic is the ‘left and top means first’ (LTMF) heuristic, which suggests that respondents tend to believe that a response scale consistently runs from left to right or from top to bottom. We conducted a web survey experiment to investigate how violations of the LTMF heuristic affect response behavior and data quality. For this purpose, a random half of respondents received response options that followed a consistent order and the other half received response options that followed an inconsistent order. The results reveal significantly different response distributions between the two groups. We also found that inconsistently ordered response options significantly increase response times and decrease data quality in terms of criterion validity. We, therefore, recommend using options that follow the design strategies of the LTMF heuristic.

论教师在物理实验教学中的作用

结合当前实验教学情况,分析教师在实验教学中所起的作用,提出在整个教学过程中教师应作为设计者、促进者、组织管理者、反思者和研究者,以确保实验课的教学效果。     

在化学演示实验中提高学生的综合素质

做好演示性实验不仅是提高化学教学效果的重要手段,也是培养学生综合素质的良好途径。为此,必须认真钻研,做好实验前的准备工作;规范操作,培养学生的科学态度和实验素质;正确引导、培养学生的观察与思维能力;增强学生的参与意识,培养学生主动探索设计实验的能力。     

计算机网络实验教学研究

针对计算机网络实验条件差这一状况,作者结合实际情况,编写了实验教材和网络实验环境的建设方案,并在以下几个方面提高学生的专业能力:分析软、硬件产品的能力;维修软、硬件产品的能力;设计软、硬件和试验开发的能力;学习、掌握和应用现有设备的能力,特别是组织构造系统应用环境的集成能力。为此,计算机网络实验教材应将计算机网络的理论基础与实验教学内容有机地组织起来,以适应社会发展的需要。     

加强高校实验队伍建设,提高实验教学质量

实验队伍建设是高等学校的一项重要工作,直接影响实验教学的质量.但由于历史等方面的原因,高校实验队伍建设还存在一些不足.文章指出必须认识到实验教学的重要性,从管理制度、政治素养培养、业务学习、实验教学改革等方面采取相应的措施,加强实验队伍建设,提高实验教学质量.

Did the escalation of the financial crisis of 2008 affect the perception of immigration-related threats? A natural experiment

In this paper, we apply a natural experiment approach, comparing specific data from the European Values Study prior to and after the escalation of the financial crisis in 2008. The aim is to disentangle the short-term effect of the crisis on the relationship between social vulnerability and immigrant-related threat perceptions for the residents of Luxembourg (natives and foreign nationals). Propensity score matching is used to ensure the balanced composition of the control group and treated group with regard to the observed covariates. The results reveal that vulnerable foreign nationals demonstrated lower perceptions of immigration-related threats after the escalation of the crisis than their pre-crisis counterparts. No significant effect of the escalation of the crisis was found among Luxembourg nationals.
