论传统文化与大学生核心价值观的培育

五千年生生不息的历史文化积淀是中华民族的根和魂。新时代高校如何用优秀传统文化涵养社会主义核心价值观,成为必须解决的重要课题。文章以山西警官高等专科学校2012、2013级学生为对象,进行了深入调查与研究,着重从教育改革新理念的树立、理想信念教育的加强、加大传统文化教育软硬件设施的投入和多元化教学渠道的开辟等四个方面进行了初步探索。文章认为传统文化教育与大学生社会主义核心价值观培育具有内在统一性。     

中国留英博士毕业生的社会流动

近年来,中国高等教育国际化的脚步越来越快,出国留学和留学归国人数逐年增长。基于一手访谈数据,探究海外博士教育是否能带给海归博士带来预期的职业发展和社会流动,并分析出海归博士归国工作后的社会流动到底呈现出什么样的特征。深入地研究了海归博士的社会流动的影响因素以及国家留学基金委奖学金在其中的作用。研究发现,海归博士的社会流动性比较小,大部分的海归博士都守住了原有的中产阶级社会地位,并没有取得很明显的向上流动;关于社会流动的影响因素,奖学金和家庭背景在博士海归归国后的社会流动中扮演重要角色。     

利用非齐次指数函数构造GM(1,1)模型背景值的新方法

文章以灰色GM(1,1)模型背景值的优化为研究目的,讨论了传统背景值构造方法适用于低增长指数序列、对高增长指数序列拟合产生滞后误差的原因,提出了利用非齐次指数函数x(1)(t):A.eBt+C在区间[k-1,k]上与横坐标轴所围实际面积来构造背景值的新方法,并对其合理性进行了证明;在不同发展系数a条件下,比较了背景值构造方法对模拟和预测精度的影响,给出了新背景值条件下GM(1,1)模型的适用范围;大量的数据模拟和模型比较表明,新背景值构造方法提高了背景值的精确性及灰预测模型的拟合精度和预测精度.     

不完全数据多重插补的Bootstrap方差估计

当对插补所得的“完整数据集”使用标准的完全数据统计方法的时候,往往会低估插补估计量的方差.Bootstrap方法(自助法)是非参数统计中的一种重要的统计方法,是基于原始观测数据进行重复抽样,能充分的利用已知数据,不需要对未知总体进行任何的分布假设或增加新的样本信息,进而再利用现有的统计模型对总体的分布特性进行统计推断.本文首先运用多重插补的方法对缺失数据进行了插补,之后利用Bootstrap方法对插补之后的数据进行了插补统计量的方差估计,结果表明运用Bootstrap方法进行插补统计量的方差估计更科学更准确.     

Inequality in Social Insurance Participation and Generosity: Do Firm Characteristics Matter?

Income inequality in China has been much documented and debated. However, one important aspect of income inequality – social insurance inequality – has been largely understudied. We use a large national panel of firm data to examine the possible influence of various firm characteristics on the inequalities in social insurance participation and generosity in the period 2004–07. Our findings reveal substantial ownership sector and regional gaps in social insurance provision by firms, with the private domestic sector and those in the central region lagging behind. Unionized firms, larger firms, and firms with greater market shares also tend to provide better social insurance to their employees. While being an exporting firm is linked with greater social insurance participation and generosity, being a purely exporting firm, however, is associated with reduced social insurance generosity. Lastly, highly educated workers receive substantially better social insurance coverage than their less educated peers. These social insurance inequalities are highly relevant as China pushes forward with establishing a unified social insurance system across urban‐rural boundaries, ownership sectors and industries.     

异质性产品质量与出口加成率

相对于已有研究分析生产率、目的市场选择和市场竞争等因素对出口加成率影响的视角,本文采用2000-2007年企业层面数据测算了28个细分制造业出口产品质量指数及按照会计方法处理的出口加成率,对中国制造业行业产品质量与出口价格加成率的关系进行实证分析.研究结果表明:出口加成率总体并没有随产品质量而提升,但影响因产品质量的异质性而存在差异,劳动密集型制造业出口产品质量显著提高了加成率,而技术和资本密集型产业仍处于阶段性“加成率陷阱”.     

Control‐based imputation for sensitivity analyses in informative censoring for recurrent event data

In clinical trials, missing data commonly arise through nonadherence to the randomized treatment or to study procedure. For trials in which recurrent event endpoints are of interests, conventional analyses using the proportional intensity model or the count model assume that the data are missing at random, which cannot be tested using the observed data alone. Thus, sensitivity analyses are recommended. We implement the control‐based multiple imputation as sensitivity analyses for the recurrent event data. We model the recurrent event using a piecewise exponential proportional intensity model with frailty and sample the parameters from the posterior distribution. We impute the number of events after dropped out and correct the variance estimation using a bootstrap procedure. We apply the method to an application of sitagliptin study.     

Linguistic instrumentalism and national language policy in Mainland China’s state print media coverage of the Protecting Cantonese Movement

This article examines the Chinese government’s use of the print media to justify the national language policy and address individuals’ concerns about the vitality of regional varieties of the Chinese language (i.e., Cantonese) in its coverage of the Protecting Cantonese Movement (July 2010) in Guangzhou. The analysis revealed that the Chinese government adopted a relatively reconciliatory response to the Movement, which apparently contested the relevant language policy. However, the media texts maintained the national policy of promoting Putonghua as inviolable, whereas they assigned Cantonese the role of the carrier of cultural tradition and stressed that the rise or fall of particular regional language depended on regional socioeconomic developments. Such media discussions showed that the state carefully managed relevant discussions about the vitality of regional Chinese varieties within the discursive space defined by legalistic, cultural, and socioeconomic development discourses. These discursive boundaries reflect the dominance of linguistic instrumentalism in the Chinese government’s language policymaking.     

非主流主流化:大学生兼职的社会学分析

社会发展、学校改革、家庭贫困、个人原因等使大学生兼职由非主流化走向主流化,甚至庸俗化。大学生兼职的动机由锻炼自己变为养活自己,在社会贬低大学生与大学生自我贬低的双重打压下,大学生兼职主流化、庸俗化不可避免,这要求社会、学校与家庭认真对待大学生兼职主流化、庸俗化问题,积极引导大学生兼职,防止因为兼职所带来的负面影响制约大学生成长与进步。     

创新、升级与培育——2013上海文化消费报告

在全国文化消费方兴未艾的背景下,上海文化消费尤为繁盛。在载体方面,创新与多元化趋势增强。由政府主导的基础型公共文化服务体系进一步完善,消费产品更加多样化,但仍存在公共文化机构数量不足、消费理念薄弱等问题。电影节、书展、动漫节、艺术节、艺博会五大节庆类公共文化平台在消费产品多元化、亲民化、国际化方面的趋势更加明显。新媒体作为市场主导的自主型文化消费载体,发展迅猛。网购、APP、微博经济、网络文学消费稳步增长。在客体方面,假日旅游和出境游消费火爆,私人影院等体验式消费备受青睐,演艺、奢侈品消费呈爆发式增长。在主体方面,上海已形成高、中、低3类消费主体并存的文化消费格局,阶层化倾向日趋明显。
