Parenting,Uncertainty, and Expert Advice: How Privileged American Families Work with Private Counselors in Their Children's College Race

This article uses privileged families who hire Independent Educational Consultants (IECs) as an instance to examine how privileged parents collaborate with individuals whom they consider educational experts to support their children in the college race. We argue that advantaged parents' anxieties about their children have created a market for IECs who provide expert advice in order to mitigate the uncertainties that these parents experience and to manage various goals that they want to achieve at an important turning point in their children's lives. Drawing primarily on interviews with parents who work with IECs, we introduce the concept of “collaborative cultivation” to analyze the processes whereby advantaged parents rely on the expertise and expert status of private counselors to cope with their and their children's vulnerability in the college race while at the same time preparing their children for the unknown future. The parental method of “concerted cultivation” reveals how elite parents rely on individuals they perceive as experts to establish “bridges” between their own social worlds and the academic worlds that appear to beyond their control. This bridging labor points to the myriad cultural beliefs enacted to justify the child‐rearing goals that privileged parents wish to accomplish by working with IECs.     

武汉城市圈建设中的“三农”问题：机遇、挑战与对策

武汉城市圈,是指以武汉为中心,以100公里为半径的城市群落,它包括武汉及其周边的黄石、鄂州、孝感、黄冈、咸宁、仙桃、潜江、天门8个城市。2007年12月,国务院批准武汉城市圈为全国资源节约型和环境友好型社会（简称“两型社会”）建设综合配套改革试验区。武汉城市圈“两型社会”的获批,在给武汉经济带来希望的同时,也给湖北“三农”问题的解决带来新的机遇秘挑战。     

青藏高原藏族民间宗教信仰生态伦理意识的思考

全球性生态危机是生态伦理得以诞生的决定性原因.生态伦理的重要使命就在于审视和反思人类对待自然环境的态度及其深层的哲学、宗教和文化根源,进而使人类和自然之间的关系得到调适和改善,在自然和人类之间建立一种新型的和谐关系.青藏高原藏族民间宗教信仰中——诸如图腾崇拜与禁忌;对神山的崇拜与禁忌;对土地的崇拜与禁忌;对神湖的崇拜与禁忌等的观念,渗透着或隐性或显性的生态伦理意识,不仅在客观上达到了人与自然的沟通,同时这种古老的智慧也许真的会成为人类走出生态危机的重要途径,从而达到人类与自然的真正和谐.

自媒体时代童书出版社群营销的逻辑研究

近年来,众多专营童书出版及分享推广的微信公众号开始崛起并引发大量关注.以微信公众号为例,从自媒体童书出版的社群营销这一角度入手,试图探讨自媒体童书出版社群营销的逻辑.研究认为,以“趣缘群体”为核心建构的社群以及通过人格化的意见领袖而形成的凝聚力,是童书社群营销的基础;社群的认同感以及由此引发的消费行为,是童书社群营销的核心:通过社群内部成员的分享和交流而建构认同感,从而让成员的消费意愿在不知不觉中得以产生,改变了传统图书“硬广告”的生硬之感;而社群的维护和发展则主要通过注重人际传播与群体传播、鼓励核心成员分享互惠、保持社群黏性以及强化意见领袖的“人格背书”等方式来促进童书出版社群营销的可生长点.     

新罗花郎道之思想特色及其审美趋向

朝鲜古代三国中期以后,新罗人及时敏锐地意识到更新意识形态的必要性。他们将从中国借鉴来的儒、佛、道思想与固有的传统思想文化糅合在一起,用于构筑自己独特的新的思想文化体系。作为一种新的思想文化形态,新罗花郎道呈现出多重复杂的内外结构。新罗人以人美为美,而这种“人美”以人内在的真、善、美和外在的容貌美、才质美为核心。这样的人物品藻之风,真实地反映着那个时代新罗人的人物评价机制和思想文化风貌,具有极其重要的研究价值和美学意义。

A new alternative to the standard F test for clustered data

The data collection process and the inherent population structure are the main causes for clustered data. The observations in a given cluster are correlated, and the magnitude of such correlation is often measured by the intra-cluster correlation coefficient. The intra-cluster correlation can lead to an inflated size of the standard F test in a linear model. In this paper, we propose a solution to this problem. Unlike previous adjustments, our method does not require estimation of the intra-class correlation, which is problematic especially when the number of clusters is small. Our simulation results show that the new method outperforms the existing methods.     

Confidence interval estimation of the difference between paired AUCs based on combined biomarkers

In many diagnostic studies, multiple diagnostic tests are performed on each subject or multiple disease markers are available. Commonly, the information should be combined to improve the diagnostic accuracy. We consider the problem of comparing the discriminatory abilities between two groups of biomarkers. Specifically, this article focuses on confidence interval estimation of the difference between paired AUCs based on optimally combined markers under the assumption of multivariate normality. Simulation studies demonstrate that the proposed generalized variable approach provides confidence intervals with satisfying coverage probabilities at finite sample sizes. The proposed method can also easily provide P-values for hypothesis testing. Application to analysis of a subset of data from a study on coronary heart disease illustrates the utility of the method in practice.
