Exploring the role of the Senate Majority Leader's political public relations efforts

Grounded in first- and second-level agenda building, this study explored the role of the U.S. Senate Majority Leader in shaping the salience of issues and issue attributes in news media coverage and policymaking in 2011. A total of 358 public relations messages, 164 newspaper articles, and 83 policymaking documents were analyzed. Significant correlations were found supporting agenda-building linkages at both levels. Different types of information subsidies were explored, including press releases, blog posts, Facebook posts, and Twitter messages.     

社会整合与中国社会发展

马克思有关社会的发展理论仍然是解释中国社会发展的主要模式,但是在具体解释一些中国历史现象时也会遇到一些问题.如何来解决这些问题,笔者试图以社会整合为视角,对中国的社会发展进行重新论证,以弥补马克思社会发展理论的不足.依据社会整合,中国社会可分为六个发展阶段:血缘社会、宗法政治社会、君主专制社会、半专制半殖民地社会、现代权力社会和权力与经济并重的社会.由中国漫长的发展过程,可以看出民主化以及市场经济的运作机制都没有充分发展起来,这将是中国未来社会的发展方向.     

SPECIAL ISSUE： ONLINE LITERATURE IN CHINA： PRESENT SITUATION AND THEORETICAL REFLECTIONS Online Writing in the Course of Discourse Transformation： A Review of Ten Outstanding Online Novels of the Past Decade

中国当代文学阅读层面上的价值认同正在经受前所未有的挑战。特别是新世纪以来，新的写作群体、写作方式不断涌现，使固有的理论批评体系遭到撞击、被撕裂，从而导致理论批评不时出现失语现象。随着网络文学的迅猛发展，非主流文学在阅读与消费环节中的影响日益增强，这就使得上述问题转化成了新的矛盾——互相不能包容的阅读隔膜。十多年来，网络上产生了海量的小说文本，逐渐形成了二十多种类型；本文兼顾时间跨度和创作类型，遴选了十年中不同类型的十部佳作，并针对它们区别于纸质媒体的艺术审美和创作特点进行了述评。     

人生转折的临界点--母题数字"十三"与藏族成年礼

数字“十三”在藏族早期文化中的大量出现,其背后具有深层的文化精神作支撑。文章从藏族“十三”的一系列民俗思想中发现,“十三”是人生重要转折时期———成年礼的临界点。这种成年礼习俗在周边民族中依然存在。     

Penalized proportion estimation for non parametric mixture of regressions

Abstract

In this article, we propose a penalized local log-likelihood method to locally select the number of components in non parametric finite mixture of regression models via proportion shrinkage method. Mean functions and variance functions are estimated simultaneously. We show that the number of components can be estimated consistently, and further establish asymptotic normality of functional estimates. We use a modified EM algorithm to estimate the unknown functions. Simulations are conducted to demonstrate the performance of the proposed method. We illustrate our method via an empirical analysis of the housing price index data of United States.     

不同震级作用下的设备 结构动力相互作用体系地震反应分析

为研究是否考虑设备 结构动力相互作用在不同地震阶段的差别,对建筑结构中常见的设备 结构相互作用体系进行了小震、中震和大震阶段的地震时程反应分析。分析了不同震级作用下考虑相互作用后给结构与设备的地震反应带来的变化。结果表明：考虑设备 结构动力相互作用与不考虑相互作用相比,结构的地震反应有较明显的区别,设备的地震反应有很大的区别,处于完全失真的状态。大震阶段由于设备和结构均进入了弹塑性阶段,刚度等主要参数发生了变化,导致动力相互作用的影响降低。虽然设备质量占结构总地震质量的比例很小,但仍会对结构位移与内力造成较大的影响。     

Robust Smoothed Rank Estimation Methods for Accelerated Failure Time Model Allowing Clusters

Smoothed Gehan rank estimation methods are widely used in accelerated failure time (AFT) models with/without clusters. However, most methods are sensitive to outliers in the covariates. In order to solve this problem, we propose robust approaches based on the smoothed Gehan rank estimation methods for the AFT model, allowing for clusters by employing two different weight functions. Simulation studies show that the proposed methods outperform existing smoothed rank estimation methods regarding their biases and standard deviations when there are outliers in the covariates. The proposed methods are also applied to a real dataset from the “Major cardiovascular interventions” study.     

论违约责任和侵权责任的竞合处理

违约责任与侵权责任是两种性质不同的民事责任,侵权责任保护的是固有利益,在合同签定、履行过程中可能有侵权性违约行为、违约性侵权行为发生,从而会产生违约责任和侵权责任竞合的情形。合理分析和处理违约责任和侵权责任竞合的不同情形,对最大限度地维护当事人的合法权益会起到积极作用。

Life Satisfaction of Rural Migrant Workers in Urban China: The Roles of Community Service Participation and Identity Integration

Abstract

China is home to approximately 245 million rural-to-urban migrant workers. The influx of migrants into urban areas has posed various challenges for local social service systems. Recently, increasing number of community services have been developed to meet the growing service demands from the migrant population. However, whether increase in community service use results in improved wellbeing among migrant workers remains critically unexplored. As such, this study examines the role of community service use in migrant workers’ life satisfaction and the potential mediating effect of identity integration in Shenzhen, China. Bootstrapped models were adopted to examine relationship among variables. Drawing from a sample of 1,087 rural-to-urban migrant workers, we found that community service use is positively correlated with both identity integration and migrant workers’ life satisfaction. Moreover, identity integration served as a partial mediator between community service use and life satisfaction. The mediating effect of identity integration was found to increase with age. This study highlights that diverse services should be implemented to address divergent needs of migrants in different age groups. Community service can also serve as a vehicle to foster integration among migrant workers in host communities, especially for older age groups. Future studies may further investigate the relationships between community social capital, community social support, quality of community-based organization and frequency of service use so as to optimize the life satisfaction of migrant workers.
