Risk Perception and Information Processing: The Development and Validation of a Questionnaire to Assess Self‐Reported Information Processing

The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information‐Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15‐item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross‐validation of the results. A two‐factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information‐Processing Questionnaire. The availability of this information‐processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.     

巨额财产来源不明罪相关问题研究

2009年2月28日通过的《中华人民共和国刑法修正案（七）》（以下简称《刑法修正案（七）》）第十四项对《中华人民共和国刑法》第三百九十五条有关巨额财产来源不明罪的规定作了修改。然而,对于巨额财产来源不明罪相关问题的讨论并没有随着《刑法修正案（七）》的颁布而停止。为了进一步深化对巨额财产来源不明罪的认识,对《刑法修正案（七）》中巨额财产来源不明罪的相关规定加以探讨,以期对巨额财产来源不明罪的进一步完善能有所裨益。     

彩票的法学解析

彩票是国家为筹集社会公益资金而发行的供人们自愿购买并据以取得获奖机会的凭证。汇集闲散资金,造福社会公益事业,是彩票的本质特征,也是彩票的道德生命和法律生命所在。彩票具有国家性、财产性、合同性、社会性等法律性质。彩票运作中包含着多重法律关系,其核心问题是发行人与购彩人之间的权利、义务如何配置。

Co掺杂SnO_2纳米粉的微结构和磁学性质

采用湿化学方法制备了Co掺杂的二氧化锡纳米粉(Sn1-xCoxO2),经研究发现,Co以离子形式存在,而不是以单质形式存在,样品中除了金红石型的SnO2相之外,没有发现其他杂质的相,随着Co掺杂含量的增加,晶粒尺寸减小,光吸收谱红移,禁带宽度线性下降。钴离子磁矩随掺杂含量的增加而减小,这可能是由于占据晶格上近邻阳离子位置的磁性离子数目增加使磁性离子成反铁磁性排列的结果。     

Nonparametric estimation of the lower tail dependence λL in bivariate copulas

The lower tail dependence λ_L is a measure that characterizes the tendency of extreme co-movements in the lower tails of a bivariate distribution. It is invariant with respect to strictly increasing transformations of the marginal distribution and is therefore a function of the copula of the bivariate distribution. λ_L plays an important role in modelling aggregate financial risk with copulas. This paper introduces three non-parametric estimators for λ_L. They are weakly consistent under mild regularity conditions on the copula and under the assumption that the number k = k(n) of observations in the lower tail, used for estimation, is asymptotically k ≈ √n. The finite sample properties of the estimators are investigated using a Monte Carlo simulation in special cases. It turns out that these estimators are biased, where amount and sign of the bias depend on the underlying copula, on the sample size n, on k, and on the true value of λ_L.     

从资产评估的角度解读中国银行业的不良资产问题

帮助中国银行业走出困境的方法之一就是剥离不良资产.以企业价值为参照,考查了银行不良资产的价值评估特征,提出了为银行不良资产处理专门立法,明确赋予金融资产管理公司重组企业资产的权利;由于银行的不良资产主要集中于大企业、大项目,可考虑先剥离这类单位的不良资产进行评估重组;协调财务审计与资产评估的关系等对银行不良资产价值评估工作的若干建议.

Asymptotic properties of the maximum-likelihood estimator for a class of birth-and-death processes admitting a unique stationary distribution

The asymptotic properties of the maximum-likelihood estimator of the parameter vector for a class of birth-and-death processes admitting a unique stationary distribution are studied. Also, it is shown that identifiability of the parameter vector with respect to the likelihood implies that the Fisher information matrix is of full rank. Two special cases of biological interest are presented. One of these, the exponential birth-and-death process, is proposed as a more appropriate model of density dependence than the logistic process.     

从广西第五次人口普查看人口迁移状况

本文根据2000年人口普查10%数据带汇总的结果,认为广西人口迁移呈上升趋势,且增长速度较快;迁出人口远大于迁入人口。在迁移人口中,以劳动适龄人口为主,女性人口占多数,以初中文化程度最多,迁移者大多是商业、服务业人员,农林牧副渔水利业生产人员和生产、运输设备操作人员。务工经商是促成人口迁移最直接的动因。人口迁移是广西农村发展重要的资金来源和经济增长点,加快了广西城市化进程。但人口迁移产生了人口分布失衡、人才流失等负面影响。因此,我们应通过户籍制度改革、加强中心城市功能建设、制定和实施科学的人才流动政策等措施,促进广西人口迁移的良性运行。
