Understanding Cumulative Risk Perception from Judgments and Choices: An Application to Flood Risks

Catastrophic events, such as floods, earthquakes, hurricanes, and tsunamis, are rare, yet the cumulative risk of each event occurring at least once over an extended time period can be substantial. In this work, we assess the perception of cumulative flood risks, how those perceptions affect the choice of insurance, and whether perceptions and choices are influenced by cumulative risk information. We find that participants' cumulative risk judgments are well represented by a bimodal distribution, with a group that severely underestimates the risk and a group that moderately overestimates it. Individuals who underestimate cumulative risks make more risk‐seeking choices compared to those who overestimate cumulative risks. Providing explicit cumulative risk information for relevant time periods, as opposed to annual probabilities, is an inexpensive and effective way to improve both the perception of cumulative risk and the choices people make to protect against that risk.     

也谈"错案追究制"

Children's gender- and age-based categorization in similarity and induction tasks

The present studies examined children's and adults' preferences for gender- or age-based categorization using similarity and inductive inference tasks. Four-year-olds, 6-year-olds, and adults looked at pictures of people and decided which of two was more like a target (similarity condition) or which shared a novel age- or gender-related property with the target (inference condition). Age or gender-based matches were possible. The results are consistent with previous findings that gender-based classification decreases with age. However, they also demonstrate that children use gender more for judging similarity than for making inferences about novel properties. Distinct patterns emerge from the two tasks: 6-year-olds and adults in both conditions categorize more by age than gender; 4-year-olds categorize by gender more than age in the similarity task, but by age more in the induction task. Only adults differentiated by property in the inference condition. These findings suggest that the salience of gender categories cannot entirely be attributed to their inductive potential. Gender has a salience beyond what would be predicted by its power for directing novel generalizations.     

西部青年对西部大开发的社会判断研究

本研究采用自编问卷就西部青年对西部大开发的社会判断情况进行了调查。结果表明:(1)大部分西部青年对西部大开发的社会判断呈一定的消极趋向;(2)西部青年对西部大开发的社会判断在农业与农民问题、民族交往问题、进城民工的权益保障问题上存在显著的地域差异,在工人下岗问题、腐败与经济犯罪问题上存在显著的职业差异,在环境问题上存在显著的文化程度差异。     

中国出入境管理体制的抉择

近年来,出入中国边境口岸的人员和货物陡增,与国际社会出入境管理体制相比较,中国的出入境管理体制还欠完善.具体表现为专属中央管理的出入境事务由各级公安部门代为管理,公安部门的属地管辖、多层管理导致区域化壁垒、政令不畅;同时,公安、外交部门在护照管理上信息不通,多头执法,易产生管理漏洞.为与国际移民法接轨构建科学的出入境管理体制,中国应尽早出台<出入境法>;改革现有的多头管理体制,争取在北京奥运会前,逐步将全国出入境管理统一置于中央政府监管之下;利用<护照法>刚刚出台之契机,统一出入境证件种类和发放程序,增加并细化签证类别,简化出入境手续;重视人员素质提升,实现从管理职能向服务职能的目标转变.     

一种新的刑法解释学观点——以刑事政策为中心的分析

刑法解释远非一种单纯探寻刑法文本含义的学究式思维游戏,而且刑法解释的依据不应当是刑法文本.刑法解释本身是一种利益衡量的活动.在这个利益衡量游戏中,无论是刑法有权解释还是刑法适用解释,刑事政策通过各种组织化的力量起着决定性的作用.
