个人教育收益率的估计与比较: 一个半参数方法

 本文运用一种变系数部分线性模型扩展了传统的明瑟人力资本收入函数,并提出了对明瑟函数中“平行性”假设的一种检验方法,以分析个人教育收益率如何受到工龄等因素的影响。通过对1991、2000以及2004等年度国家统计局城镇居民收入调查数据的分析,揭示出近二十年来我国城镇居民中不同工龄的人们的教育收益率存在明显区别,其中人教育收益率最高的始终是在1980年代中后期参加工作的群体。对导致我国教育收益率这种特殊现象的原因作了分析。     

Detecting homogeneous segments in DNA sequences by using hidden Markov models

In recent years there has been a rapid growth in the amount of DNA being sequenced and in its availability through genetic databases. Statistical techniques which identify structure within these sequences can be of considerable assistance to molecular biologists particularly when they incorporate the discrete nature of changes caused by evolutionary processes. This paper focuses on the detection of homogeneous segments within heterogeneous DNA sequences. In particular, we study an intron from the chimpanzee α-fetoprotein gene; this protein plays an important role in the embryonic development of mammals. We present a Bayesian solution to this segmentation problem using a hidden Markov model implemented by Markov chain Monte Carlo methods. We consider the important practical problem of specifying informative prior knowledge about sequences of this type. Two Gibbs sampling algorithms are contrasted and the sensitivity of the analysis to the prior specification is investigated. Model selection and possible ways to overcome the label switching problem are also addressed. Our analysis of intron 7 identifies three distinct homogeneous segment types, two of which occur in more than one region, and one of which is reversible.

No Mind Reading Necessary: Conducting Evidence-Based Electronic Resource Marketing and Outreach Using Marketing Research Assessment

Abstract

In her presentation entitled “No Mind Reading Necessary: Conducting Evidence-Based Electronic Resource Marketing and Outreach” at the North Carolina Serials Conference April 2019, Kate Hill discussed marketing research strategies and outreach tools used to increase online users’ access to electronic resources and primary resources. In an effort to connect users to seldom-used resources, Jackson Library collaborated with university partners to develop surveys to identify the information-seeking behavior of its users and apply the gathered marketing research to strategically plan outreach activities.     

新文类与亚文化

新媒体和文学的结合催生出一批迥然有别于传统纸媒文学的新文类作品,而被流行化的亚文化构成了它们的重要话语资源,新文类中最常见的亚文化种类有同性恋亚文化、神秘亚文化和游戏动漫亚文化等,这些亚文化中蕴涵的抵抗和边缘因素在消费时代成为商业文化的卖点,被流行化快餐化之后作为一种＂奇观＂投合了都市青少年群体追求新奇刺激的猎奇心态,因而在新媒体平台上成为新的时尚和潮流。

Neo‐liberalism by Decay? The Evolution of the Czech Welfare State

In this article we analyse the evolution of the Czech welfare state and we examine the factors explaining its path. We show that although the Czech welfare regime exhibits a 'mixed profile' that includes conservative and universalist elements, it is increasingly moving in a more liberal, residualist direction – not because of conscious steps but rather through decay. Governments have often zig-zagged in their policies and resorted to symbolic reforms at times rather than implementing ideologically based, consistent policies. We argue that historical and sociological institutionalism combined with a social-capital approach can explain this decay better than the more common arguments about economic pressures combined with ideological hegemony or the protest-avoidance strategy. In particular, the social capital approach adds to our institutional framework by explaining why cutbacks in welfare programmes have not met much opposition, even though public opinion surveys consistently show support for more generous welfare policies, and why policies have deviated so much from political rhetoric.     

累积的异质性：生命历程视角下的老年人分化

本文以生命历程理论为研究视角，以深度访谈的方法收集老年人“主诉”的关于过去的生活资料，试图通过对个人能动性与生命历程时间性的强调，来分析个体生命历程与社会变迁的相互嵌入过程，以及这一过程中不断分化的内部机制。研究发现，老化的过程是一个随时间推移不断累积与分化的过程，累积因素的先后顺序对个体之间的分化具有重要意义，累积是生命历程资本遭遇生命历程风险的结果，是社会结构与个人能动性相互作用的动态过程，其中社会政策的变迁对累积过程具有决定性的影响。

社区仪式及其在社区社会资本创建中的作用--以西北弓村"转灯"仪式的实地研究为例

本文通过对西北弓村"转灯"仪式的实地研究与描述,分析了仪 式在社区社会资本创建中的意义,认为社区民间仪式促进了居民之间的交往与沟通,有利于提高居民的参与、合作水平和自组织能力.文章同时指出,社区仪式的衰退会造成社区社会资本的缺失,只有通过仪式创新或创建其他形式的组织或活动,才能从一定程度上弥补这种缺失所造成的影响.
