‘Don't you know. They're talkin' 'bout a revolution. It sounds like a whisper.’ For an anthropological reading of the ‘Arab Spring’

The paper analyses the common sentiment created around the so-called Arab spring, upon the basis of a narrative developed and disseminated by the mass media as well as in the specialist literature with regard to these complex, varied, and consequential events. It concerns a vision which gathers and promotes an awakening of social dignity through actions of popular revolt and protest, a demand for political change which has cost the peace and lives of too many people, of entire societies.     

阿凡提“话语”的土地情结和金钱意识——在多重交往中的“腹地效应”

阿凡提“话语”表现的良知和德行、勤劳和智慧、公平和正义等内涵,实际上是积淀于西域人生命最深层的一种无意识的“土地情结”演绎的精神特征;而其中描写的人性堕落和贪欲以及西域人对金钱的渴望和财富创造欲,又是“土地”结出的“另类之果”。不过,阿凡提“话语’’的金钱意识刻有阿拉伯商业文化的烙印,更与本土的沙漠文化、绿洲文化及中原文化融合而不断生成新质,形成了一种永不衰竭的“腹地效应”。     

基础会计课程螺旋式教学过程的设计探究——以会计要素为例

基础会计是会计专业的入门课程,如何上好专业入门课,许多教师都提出了好的方法.文章通过在基础会计其中一个单元——会计要素的教学中运用螺旋式教学法,从实践的角度验证了其可行性及优越性,为同行利用螺旋式教学法提供借鉴.     

同乡的力量：同乡聚集对农民工工资收入的影响

中国的城乡流动中存在同一籍贯或同一来源地的农村流动人口的就业聚集现象--“同乡聚集”。本研究使用2010年珠三角和长三角外来务工者调查的数据,采用倾向分数匹配和异质性干预模型等方法,考察了以籍贯为族群基础的同乡聚集对城市农民工经济收入的影响。研究发现,尽管同乡聚集者的收入优势受到异质性和自我选择机制的影响,但同乡聚集仍有助于提高农民工的工资收入。越倾向于同乡聚集的农民工,从同乡聚集中获得的收入回报越高。     

FDI 对我国就业影响的动态效应与区域差异u1——基于动态面板数据模型的广义矩(GMM)分析方法

本文选取1996—2011年我国的省际面板数据,利用动态面板数据模型广义矩(GMM)分析方法,对 FDI 对我国就业影响的动态效应与区域差异进行了实证分析.研究结果发现,FDI 对我国就业影响的区域差异显著,整体上具有显著的挤出效应;仅滞后1期 FDI 对中部地区当年就业的创造效应显著,而其他时域的 FDI 对当年就业的影响均是负向的.因此,引进 FDI 无法吸纳更多的劳动力,依靠 FDI 很难缓解国内的就业压力.     

Meta-Analysis as a Research Synthesis Methodology: Cause for Concern

ABSTRACT

The use of meta-analysis is growing in popularity. It is based on the fundamental notion of the effect size, and a critical assumption is that effect sizes based on different measures are directly comparable. In this article it is argued that the direct comparability of effect sizes across measures implies the invariance of the effect sizes across these measures. A model of standardized mean difference (SMD) effect size invariance is developed, based on multifacet generalizability theory, which shows that SMD effect size invariance requires certain validity invariance conditions to hold. One implication of these findings is that the direct comparability of SMD effect sizes based on different measurement procedures is an empirical matter requiring testing prior to conducting a meta-analysis. Findings are also discussed suggesting that violations of one of these conditions—universe score validity invariance—can bring about substantial differences across SMD effect sizes as a function of measurement procedure. These findings suggest the need for a more refined use of meta-analysis since meta-analytic results may be adversely impacted by the lack of direct comparability of effect sizes based on different measures.     

“帝王作家”的人文情怀——二月河历史小说论

本文阐述了二月河作品的人文情怀:指出了他的人文情怀首先摆脱了狭隘的阶级论、汉族中心的观念,对历史的评价更显人性化;其次在人物形象的塑造上,突出了人性内涵,表现出了人文精神;第三他怀着对我国传统文化的钟爱与敬仰之情,对古典文化进行了尽情展示;第四他"关注弱势人群的心理渴望与需求企盼",寄托了现实中日益远去的人文关怀。     

基于牛鞭效应的供应链信息共享集成优化研究

供应链信息共享是缓解牛鞭效应的重要途径之一,但在实际应用中,成功实现供应链信息共享的案例却很少。针对这种情况,分析了供应链信息共享失败的原因,对当前解决方案存在的不足,提出了一种基于客户反馈修正的供应链信息共享模型,对该模型的可行性进行了讨论,并给出了该信息共享模型的一个具体应用案例。     

城门失火殃及池鱼吗？来自债券违约的分析

近年来,我国债券违约事件频发,对债券市场的平稳运行造成威胁。以2020年11月永煤债券违约为外部冲击,从地区、行业、评级机构与承销商四个层面,基于2020年债券市场日度数据,利用事件研究法与双重差分模型分析了AAA级国有企业债券违约对债券市场影响的溢出效应。研究发现,永煤债券违约事件导致债券一级市场发行规模缩小与发行成本提升,并显著提高了二级债券市场存续债券的回报。从短期市场反应来看,违约事件造成的负面溢出效应(异常回报提升)同时存在于地区、行业、评级机构与承销商层面;从长期影响来看,违约事件导致的存续债券收益率提升的负面冲击仅在地区和行业间存在。异质性分析表明,违约事件对低承付能力地区、低市场竞争程度行业、由内资背景机构评级以及低声誉机构承销的债券负面影响更加显著。进一步检验发现,上述短期负面溢出效应在高等级(AAA)债券组中更加显著,并且评级机构的评价标准并没有受到该违约事件的影响,说明信用评级膨胀问题仍然严重。因此,监管部门应加强对债券市场的引导,从债券市场信息中介(评级机构与承销商等)角度采取措施来防范与降低债券违约风险。     

Single-machine scheduling with general sum-of-processing-time-based and position-based learning effects

In this paper, we propose a new learning effect model in which the actual job processing time is a general function of the normal processing time of jobs already processed and its scheduled position. This model has the advantage that different learning curves can be constructed easily, such as the plateau function. It is found that most of the models in the literature are special cases of our proposed model. The optimal sequences for some single-machine problems are then provided.
