Framing Falun Gong: Xinhua news agency's coverage of the new religious movement in China

Falun Gong caught the eyes of the Beijing leadership when more than 10,000 of its practitioners gathered at the Zhongnanhai government compound in Beijing on April 25, 1999. It attracted the attention of the world when the Chinese Communist Party (CCP) started cracking down on the group three months later, claiming this to be the most serious political incident since the student uprising at Tiananmen Square on June 4, 1989. Scholars have attempted to contextualize the cultural, political, and economic climate in contemporary China that allowed this group to rise in a relatively short period and to assess the causes of the CCP's nationwide campaign oppressing the group. Relatively little attention, however, has been paid to exploring the media's role in supporting the government's cause in this campaign. This study examines journalistic narrative and framing of Falun Gong as a social threat in one news organization's attempt to legitimize the government's crackdown against the group. Although the economic reforms and political relaxation since the 1980s might have expanded the media's latitude, the press, especially state-owned media outlets, still functions as an agent for the Beijing regime in important political and social issues. This paper shows how journalists, through news frames, construct particular parameters within which to assess the ‘reality’ about Falun Gong.     

TiO2掺杂Ag/SnO2电接触材料物理性能的研究

采用机械混合法、溶胶-凝胶法制备TiO2掺杂Ag/SnO2电接触材料。实验结果表明,在机械混合法中,Ti4 不能进入SnO2的晶格,也没有提高SnO2的电导率;在溶胶-凝胶法中,Ti4 能够很好地进入SnO2的晶格,从而改善触头的电性能。微观组织分析表明:纳米触头中SnO2的分布要比非纳米触头中SnO2分布均匀,可以避免因SnO2的富集而降低电导率,从而提高Ag/SnO2触头的电性能和电寿命。

Changes in anatomy instruction and USMLE performance: Empirical evidence on the absence of a relationship

Anatomy instruction has evolved over the past two decades as many medical schools have undergone various types of curricular reform. To provide empirical evidence about whether or not curricular changes impact the acquisition and retention of anatomy knowledge, this study investigated the effect of variation in gross anatomy course hours, curricular approach (stand‐alone versus integrated), and laboratory experience (dissection versus dissection and prosection) on USMLE Steps 1 and 2 Clinical Knowledge (CK) scores. Gross anatomy course directors at 54 United States schools provided information about their gross anatomy courses via an online survey (response rate of 42%). Survey responses were matched with USMLE scores for 6,411 examinees entering LCME‐accredited schools in 2007 and taking Step 1 for the first time in 2009. Regression analyses were conducted to examine relationships between gross anatomy instructional characteristics and USMLE performance. Step 1 total scores, Step 1 gross anatomy sub‐scores, and Step 2 CK scores were unrelated to instructional hours, controlling for MCAT scores. Examinees from schools with integrated curricula scored slightly lower on Steps 1 and 2 CK than those from stand‐alone courses (effect sizes of 2.1 and 1.9 on score scales with SDs of 22 and 20, respectively). Examinees with dissection and prosection experience performed slightly better on Step 2 CK than examinees in courses with dissection only laboratories (effect size of 1.2). Results suggest variation in course hours is unrelated to performance on Steps 1 and 2 CK. Although differences were observed in relation to curricular approach and laboratory experience, effect sizes were small. Anat Sci Educ 6: 3–10. © 2012 American Association of Anatomists.

固定辙叉区轮轨静态接触几何关系计算

针对固定辙叉特殊的轨线布置及复杂的轮轨接触关系,建立固定辙叉区轮轨接触几何关系算法,分析固定辙叉区沿辙叉走行方向主要接触参数的变化规律以及各关键断面轮轨接触点变化情况。结果表明:在辙叉轮载过渡段轮轨接触参数变化规律复杂,结构不平顺变化幅值最大且波长较短;轮对横移量增加,轮轨接触几何参数增大,轮轨动力作用增强;辙叉咽喉区和轮载过渡段辙叉侧轮轨接触点变化存在突变。提出应合理设计辙叉区轮载过渡段结构参数,优化轮轨接触几何关系,进而改善列车通过时辙叉的受力性能。     

传统道德与现代经济伦理的内在关涉

以“可持续发展”、“科学的资源价值”和“生态生产”为主题内容的现代经济伦理深深地扎根于深厚的儒道互补的传统道德之中，其内在关涉不仅表现在对传统道德精髓的一脉相承，更重要的还是在对传统道德的辩证扬弃，执著于实现在经济活动中“经济人“与“道德人”的和谐统一。     

黄土隧道衬砌背后空洞对隧道衬砌结构影响分析

衬砌裂损是隧道病害中常见的问题,也是严重威胁结构安全的一个重要因素。文章针对铁路运营隧道病害的检测结果,对衬砌背后空洞进行平面弹塑性计算分析,得出不同位置、不同大小的空洞以及空洞群对结构各截面受力及位移影响的系统认识,明确提出衬砌结构与围岩结合的不紧密性是恶化衬砌受力条件、造成围岩进一步松动、进而造成衬砌裂损的一个重要原因;还对直墙式及曲墙式衬砌所受到的不同影响进行了比较分析,认为曲墙式衬砌拱部结构能较好地将内力传递给边墙,由边墙部分承受较大的水平抗力,优化了整体结构的受力,从而降低背后空洞对衬砌结构的影响。通过对计算结果的系统分析和研究,合理解释了实际检测中的问题。     

二重变奏:论明代任瀚的政治人生

本文主要论述了明代任瀚积极求取功名以“用世”，但他为人正直公正，不阿附权贵，当时的政坛没有他施展政治抱负的客观环境。由于秉公办事开罪权贵，受到打击排挤，不得不“恬退”归隐以获取政治人格的独立，他以各种方式潜在地或明或暗与政治发生关系。任瀚一方面高歌用世，另一方面又浅唱隐退的二重变奏，其“用世”与“恬退”这一矛盾的政治人生态度在他身上却发生了符合逻辑的关联。     

Preliminary Analysis of Crystallization of Na2SO4 Solution in Silicate Cultural Relics

ABSTRACT

Currently, there is a lack of research on the migration and distribution of soluble salt solutions in the pores of fragile silicate cultural relics, especially the thermodynamic changes during crystallization, and the forces causing the destruction of cultural relics. Thus, this paper used infrared thermal imaging analysis and extended depth-of-field microscopy to observe the changes in temperature, morphology, migration, and crystallization rate of Na₂SO₄ solution – the most typical solution that causes damages to cultural relics – in the crystallization process and in different capillary pores. The results show that the formation of soluble salt crystal nuclei and subsequent crystal growth mainly occurred in the liquid phase region below the ambient temperature, and then the salt crystals in the deliquescent state became more compact due to the attractive force generated from liquid-phase water evaporation. Additionally, three stages of migration and crystallization of the salt solution in different capillary pores were found. Large-area crystals appeared in the capillary pore with a large diameter, and bubbles were generated. This is likely because the surface tension of the Na₂SO₄ solution decreased with increasing concentration, and the solubility of the air dissolved at the solid–liquid interface of the mouth of the capillary pore and the pressure in the capillary pore decreased. A self-designed double-layer contact surface internal pressure method and extended depth-of-field microscopy were used to carry out real-time online observation of the force applied on the contact surface during the crystallization of the salt solution. It was found that the airflow determined the direction of capillary movement of the solution, and water migration determined the laminar flow in the capillary pore. Salt crystallization played a role in distortion and shape-fixation of pores. Small spikes in the mass indicated that the expansion–contraction force generated by the salt solution during the crystallization process was in a state of constant change, and the degree of expansion was always slightly more significant than the change caused by contraction. Expansion forces dominated the surface of the sample. In this paper, the change in crystallization and the forces of the soluble salt solution were analyzed.
