社会主义制度文明论略

人们习惯于把人类文明看成物质文明和精神文明之和 ,而忽视了人类文明中还有一种独立的文明形态 ,即制度文明。当前 ,我国推行依法治国 ,大力建设社会主义民主法制 ,既表达了对制度文明形态的肯定 ,更是社会主义制度文明建设的一种关键性实践。具体来说 ,社会主义制度文明建设应从制度观念、制度文化、制度规则、制度组织等方面全面展开     

从“统战体制合作”到“政党体制合作”——新世纪新阶段多党合作发展的前瞻性思考

中国共产党领导的多党合作制度是我国一项基本政治制度,党派合作模式问题是多党合作制度发展的核心问题。新中国成立后,我国选择＂统战体制合作＂的党派合作模式,不仅体现了社会历史条件的客观要求,而且显示出了这一制度安排的长处和优势。新世纪、新阶段,多党合作制度的完善与发展,应坚持科学发展观,遵循人类政治文明发展的总趋势,逐步实现向＂政党体制合作＂的合作模式转变。     

论地方高校人力资源的优化配置

地方高校人力资源的开发与优化,应该选择在制度创新上下工夫。针对地方高校人力资源现状的特点,选择制度安排与创新探索,从“官”念组织层面、人事制度层面、心理机制层面进行有益思考,以实现系统内部各要素之间的整合,达到才尽其用、人适其事的目的。     

“异域”之异表现在哪里?——解析萨伏伊《异域》

萨伏伊在《异域》里把美国南方视为一个不同于美国北方的“异域”,从系统力量之异、种族关系之异和种族心理之异的角度展现“异域”之异,揭露黑人的悲剧人生和白人种族主义制度的非人性和非理性.政治之异、司法之异和大众媒体之异显示了美国社会系统力量的冲突和内耗,抨击了不合理社会制度的反人类性和反文明性.种族情结、种族疏离和信用危机引发的种族关系之异严重威胁着社会稳定和人身安全,恶化了美国的种族关系;身份焦虑、歧视焦虑和越界焦虑通常会深化美国社会的种族心理之异,加剧黑人的双重意识危机,妨碍美国多元化社会的建立和发展.     

Approximate reference priors for Gaussian random fields

Reference priors are theoretically attractive for the analysis of geostatistical data since they enable automatic Bayesian analysis and have desirable Bayesian and frequentist properties. But their use is hindered by computational hurdles that make their application in practice challenging. In this work, we derive a new class of default priors that approximate reference priors for the parameters of some Gaussian random fields. It is based on an approximation to the integrated likelihood of the covariance parameters derived from the spectral approximation of stationary random fields. This prior depends on the structure of the mean function and the spectral density of the model evaluated at a set of spectral points associated with an auxiliary regular grid. In addition to preserving the desirable Bayesian and frequentist properties, these approximate reference priors are more stable, and their computations are much less onerous than those of exact reference priors. Unlike exact reference priors, the marginal approximate reference prior of correlation parameter is always proper, regardless of the mean function or the smoothness of the correlation function. This property has important consequences for covariance model selection. An illustration comparing default Bayesian analyses is provided with a dataset of lead pollution in Galicia, Spain.     

Personalized Neural Networks Underlie Individual Differences in Ethnic Identity Exploration and Resolution

This study examined how ethnic identity relates to large-scale brain networks implicated in social interactions, social cognition, self-definition, and cognitive control. Group Iterative Multiple Model Estimation (GIMME) was used to create sparse, person-specific networks among the default mode and frontoparietal resting-state networks in a diverse sample of 104 youths aged 17–21. Links between neural density (i.e., number of connections within and between these networks) and ethnic identity exploration and resolution were evaluated in the full sample. Ethnic identity resolution was positively related to frontoparietal network density, suggesting that having clarity about one’s ethnic group membership is associated with brain network organization reflecting cognitive control. These findings help fill a critical knowledge gap about the neural underpinnings of ethnic identity.     

手机App列表信息在信用风险评价中的应用——基于互联网借贷平台的实证研究

随着互联网的发展和智能手机的普及，用户手机数据被用来评估借款人的信用风险，使用到的数据有通讯记录、短信息接发、移动轨迹、用户行为数据等，而本文研究了手机上所安装的App列表和借款人信用风险之间的关系。通过对某大型互联网借贷平台上的个人借贷数据以及借款人手机上安装的App列表数据的分析发现，手机上安装的App和借款人的信用状况存在关联关系。安装生活类、金融类和买房买车类App的借款人比没有安装这些App的借款人信用风险低；其中，记账类App、外卖类App、股票类App和买房类App对借款人的信用风险有较强的识别能力。把手机App列表信息加入信用风险评价模型之后，信用风险评价模型的区分能力得到显著提高。     

周期波动与需求不足--我国有效需求不足的系统分析

从短缺经济到相对过剩是我国经济发展的重大进步.我国需求不足是国内经济周期与世界经济周期共同作用的结果.形成需求不足的原因既有外部性的亚洲金融危机引起的出口下降,也有国内特定经济制度造成的投资和消费需求不足,而起决定作用的是长期计划经济和粗放式增长方式造成的经济低效率和居民低收入.应将宏观经济管理手段与制度创新相结合,加快实现两个转变,才能从根本上克服有效需求不足的问题.     

Term Structures of Credit Spreads with Incomplete Accounting Information

We study the implications of imperfect information for term structures of credit spreads on corporate bonds. We suppose that bond investors cannot observe the issuer's assets directly, and receive instead only periodic and imperfect accounting reports. For a setting in which the assets of the firm are a geometric Brownian motion until informed equityholders optimally liquidate, we derive the conditional distribution of the assets, given accounting data and survivorship. Contrary to the perfect‐information case, there exists a default‐arrival intensity process. That intensity is calculated in terms of the conditional distribution of assets. Credit yield spreads are characterized in terms of accounting information. Generalizations are provided.
