新青年派对青年人生观的重塑与现代价值

社会转型对青年人的影响具有历史的共性。20世纪初,以陈独秀、胡适、李大钊等为主体的新青年派主张青年人要树立正确的人生观,要以积极进取、奋发有为的人生态度追求幸福、承担社会责任。当前,我国社会正进入从传统型社会向现代型社会转变的转型期,但新青年派的人生观对青年人生观的影响仍然存在。新青年派的人生观主张既反映了转型期社会的特点,也反映了转型期中青年人应该具有的人生观,因此具有重要的现代价值。     

Bayesian adjustment for unidirectional misclassification in ordinal covariates

In this paper, we study the identification of Bayesian regression models, when an ordinal covariate is subject to unidirectional misclassification. Xia and Gustafson [Bayesian regression models adjusting for unidirectional covariate misclassification. Can J Stat. 2016;44(2):198–218] obtained model identifiability for non-binary regression models, when there is a binary covariate subject to unidirectional misclassification. In the current paper, we establish the moment identifiability of regression models for misclassified ordinal covariates with more than two categories, based on forms of observable moments. Computational studies are conducted that confirm the theoretical results. We apply the method to two datasets, one from the Medical Expenditure Panel Survey (MEPS), and the other from Translational Research Investigating Underlying Disparities in Acute Myocardial infarction Patients Health Status (TRIUMPH).     

以党建促脱贫: 一项政治社会学视角的中国减贫经验研究

1986年，党建扶贫作为中国扶贫开发国家行动起步的标志，同步于改革开放的伟大历史进程中。经过30年的演进，形成当下精准扶贫、精准脱贫国家战略的核心引擎。从学理上看，以党建促脱贫所包含的将贫困治理、社会治理整合一体的发挥制度优势相嵌合，为政治社会学研究社会内聚和国家权威整合及一致性的当代主题转向，形成本土建树，提供了最为前沿的鲜活案例。     

轻与重：美丽的悔——读张枣《镜中》

张枣很早就开始尝试对古典诗学传统的吸收和借鉴,并进行了比较成功的试验,《镜中》便是一例。通感和＂词义借用＂使＂悔＂变得美丽轻盈,人称转换造成了心理空间腾挪,＂镜中＂这一出色运用的意象统摄了全诗,三者共同织就一个复杂的文本。这些技巧帮助平衡了诗中的轻与重,取得了良好的效果。     

宏观经济调控机构之间相对权力的实证分析——基于履历的部长相对地位之估计

我国政府对宏观经济运行有着较强的影响力。通过宏观经济政策调控经济是政府主要的影响途径之一。显然,由于调控的跨部门色彩,了解各部委在国务院的相对权力对理解我国宏观经济调控有着重要的帮助。在官本位的中国,部长的地位与其所在机构的相对权力有着密切的关系。本文从这点出发,通过履历法分析了四大宏观经济调控机构的相对权力。最近五届政府官员的履历表明:发改委的相对权力高于其他部门,人民银行次之,两者的差距相对较小;商务部第三,财政部第四。     

被神经性毒剂染毒的蛋白IgG中有机磷加合物的研究

本文对IgG与神经性毒剂的加合物进行了研究。用过量的神经性毒剂(沙林、梭曼、VX、环沙林)对IgG(人、大鼠IgG)进行体外染毒,用胰蛋白酶进行酶解,所得样品用Q Exactive LC-MS/MS方法进行分析鉴定,发现了IgG与神经性毒剂的加合物肽段。其中,从人的IgG中发现了4个被标记的肽段,从大鼠的IgG中发现了1个被标记的肽段,另外,还从肽段的二级谱图中发现了酪氨酸加合物的特征离子碎片。本文首次发现了被神经性毒剂标记的IgG肽段,进而说明IgG是鉴定神经性毒剂中毒的一类重要的标记蛋白。     

Fitting competing risks data to bivariate Pareto models

This paper revisits two bivariate Pareto models for fitting competing risks data. The first model is the Frank copula model, and the second one is a bivariate Pareto model introduced by Sankaran and Nair (1993 Sankaran, P. G., and N. U. Nair. 1993. A bivariate Pareto model and its applications to reliability. Naval Research Logistics 40 (7):1013–1020. doi:10.1002/1520-6750(199312)40:7%3c1013::AID-NAV3220400711%3e3.0.CO;2-7.[Crossref], [Web of Science ®] , [Google Scholar]). We discuss the identifiability issues of these models and develop the maximum likelihood estimation procedures including their computational algorithms and model-diagnostic procedures. Simulations are conducted to examine the performance of the maximum likelihood estimation. Real data are analyzed for illustration.     

Stemming retail leakage with a sense of community: Leveraging the links between communal ties and shopping decisions

Retail business development is a broad goal for both private business interests as well as local policymakers, yet the goal of retail opportunities for local residents themselves is often seen as secondary. This paper considers the argument that retail opportunities and sense of community are in fact linked in important ways, links that reinforce the social fabric of a community and/or neighborhood. The paper first briefly reviews the inherent linkages between retail shopping and local development patterns, and then considers the sense of community in the context of Garfield County in western Colorado. Based on the key questions derived from this background, we formally test the inter-relationship between local retail spending and sense of community from detailed survey data, then more broadly consider the factors that critically shape a locality's “sense of community.” These findings shape several important policy implications.     

用工业CT技术测量储层岩芯饱和度分布

认识储层岩石中含油饱和度及饱和度分布,对驱替机理的深入研究是非常重要的。为了搞清储层岩石在驱替过程中的饱和度分布情况,应用工业CT技术,提出了一种储层含油岩芯被驱替后的饱和度分布的CT密度差测量方法。在岩样的同一断面,分别对干岩样、饱和岩样及在驱替后的岩样进行CT扫描,重建相应的断层图象,测量所建图象的灰度值,计算出相应的密度值,用密度差法计算出饱和度及其分布值。在γ射线工业CT机“CD-300BG”上对某油田岩样进行了实际测量,获得的结果说明,采用CT密度差法测量饱和度分布是有效的。该方法与常规驱替法相比较,具有快速、精度高、无损岩样和能模拟地层状态测量等特点,是油田开发、油藏描述和地层评价的一种新的有效方法。
