An omnibus two-sample test for ranked-set sampling data

We develop an omnibus two-sample test for ranked-set sampling (RSS) data. The test statistic is the conditional probability of seeing the observed sequence of ranks in the combined sample, given the observed sequences within the separate samples. We compare the test to existing tests under perfect rankings, finding that it can outperform existing tests in terms of power, particularly when the set size is large. The test does not maintain its level under imperfect rankings. However, one can create a permutation version of the test that is comparable in power to the basic test under perfect rankings and also maintains its level under imperfect rankings. Both tests extend naturally to judgment post-stratification, unbalanced RSS, and even RSS with multiple set sizes. Interestingly, the tests have no simple random sampling analog.     

Impact of support networks for breastfeeding: A multicentre study

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Replication: Revisiting Tversky and Shafir’s (1992) Disjunction Effect with an extension comparing between and within subject designs

Does uncertainty about an outcome influence decisions? The sure-thing principle (Savage, 1954) posits that it should not, but Tversky and Shafir (1992) found that people regularly violate it in hypothetical gambling and vacation decisions, a phenomenon they termed “disjunction effect”. Very close replications and extensions of Tversky and Shafir (1992) were conducted in this paper (N = 890, MTurk). The target article demonstrated the effect using two paradigms in a between-subject design: here, an extension also testing a within-subject design, with design being randomly assigned was added. These results were consistent with the original findings for the “paying to know“ problem (original: Cramer’s V = 0.22, 95% (CI) [0.14, 0.32]; replication: Cramer’s V = 0.30, 95% CI [0.24, 0.37]), yet not for the “choice under risk” problem (original: Cramer’s V = 0.26, 95% CI [0.14, 0.39]; replication: Cramer’s V = 0.11, 95% CI [−0.07, 0.20]). The within-subject extension showed very similar results. Implications for the disjunction effect and judgment and decision-making theory are discussed, and a call for improvements on the statistical understanding of comparisons of between-subject and within-subject designs is introduced.

行政法视角下的不动产登记制度--兼评《不动产登记暂行条例》

建立不动产统一登记制度,是国务院机构改革和职能转变的重要内容,是提高不动产交易效率和安全性的必要之举,也是完善社会主义市场经济体制的必然要求,对保护不动产权利人合法权益、提高政府治理效率具有重要意义。相关的法律中有关不动产登记的不同规定,应当尽快随之配套修改,做好各项规定的衔接。登记机构的职责还应进一步细化与明确,将不动产统一登记制度整体性纳入简政放权的进程中。     

中美高校学生申诉制度的比较分析--以北京邮电大学和麻省理工学院为例

高校学生申诉制度是维护学生合法权益的救济制度。针对我国高校现行申诉制度的一些不足之处,从申诉委员会的组成、委员会的权利、学生违纪处理及申诉的一般程序、受理学生申诉的范围等几个方面,以北京邮电大学和麻省理工学院为例,对比研究了中美高校的学生申诉制度,并在此基础上提出完善我国高校学生申诉制度的建议：①淡化申诉委员会的行政色彩;②适当扩大申诉委员会的权利;③在处分结论得出前要充分发挥听证会的作用;④严格执行回避制度;⑤进一步扩大受理学生申诉的范围,确保学生的各种合法权益都能得到保护。     

法语联盟语言课堂教学研究及对孔子学院的启示

在世界各国国力竞争日益激烈的今天,民族语言的国际推广成为增强本国文化软实力、提升综合国力的重要举措。作为我国汉语言国际推广龙头的孔子学院如何尽快解决对外汉语教学的现存问题从而更有成效地推进中国语言文化对外传播是汉语言国际推广中的重要命题。法国法语联盟作为世界上历史最悠久、规模最大的语言国际推广机构,其成熟语言教学理论和成功实践经验对孔子学院的对外汉语教学工作具有重要借鉴和指导意义。     

Perceptions of Randomized Security Schedules

Security of infrastructure is a major concern. Traditional security schedules are unable to provide omnipresent coverage; consequently, adversaries can exploit predictable vulnerabilities to their advantage. Randomized security schedules, which randomly deploy security measures, overcome these limitations, but public perceptions of such schedules have not been examined. In this experiment, participants were asked to make a choice between attending a venue that employed a traditional (i.e., search everyone) or a random (i.e., a probability of being searched) security schedule. The absolute probability of detecting contraband was manipulated (i.e., 1/10, 1/4, 1/2) but equivalent between the two schedule types. In general, participants were indifferent to either security schedule, regardless of the probability of detection. The randomized schedule was deemed more convenient, but the traditional schedule was considered fairer and safer. There were no differences between traditional and random schedule in terms of perceived effectiveness or deterrence. Policy implications for the implementation and utilization of randomized schedules are discussed.     

智库的大众传播操作：由胡佛研究所引申

智库要实现影响舆论、进而影响公共政策的目的，首先必须通过各种大众传播工具对外宣传推广其研究人员和研究成果，使其得到公众的认可。世界著名智库胡佛研究所通过对现代大众传播技术的充分合理运用，进一步提高了其在美国及世界上的地位和影响力，其成功经验，值得我国智库学习借鉴。     

中国文化对外传播效果研究——对5国16所孔子学院的调查

本文通过对美国、日本、俄罗斯、泰国、黎巴嫩5个国家16所孔子学院的调查发现:当前孔子学院在全球范围内取得了一定的传播效果；但不同层次的中国文化传播效果存在较大差异；中国文化在不同文化圈层,尤其是儒家文化圈层和非儒家文化圈层中的传播效果有很大不同；国与国之间也存在较大差异.本文提出,针对非儒家文化国家,要让中国的物质文化先走出去,行为文化、精神文化可暂时缓行.     

电子政务新时代与我国民主政治发展新趋势

电子政务是互联网时代信息技术与政府政务信息公开相结合的重要成果,科学运用电子政务的特殊技术平台,能极大提升政务公开程度和政务服务水平。电子政务在我国突飞猛进的发展,日益成为政府顺应民意、提高政治自觉的有效工具;也越来越成为公民知情,以及政治参与和民主监督的重要渠道。中国特色社会主义民主政治的改革在不断制度化、规范化、程序化发展过程中,也呈现出信息化的新趋势。电子政务在我国民主政治信息化的新趋势中发挥了至关重要的作用。
