A Review of Plant Specific PRAs

A large number of PRA studies have been completed for specific plants at specific sites. From these studies, taken individually or collectively, many significant insights have evolved into items important to risk and safety. The content of this paper is primarily based on the material contained in the EPRI funded review of five PRA studies: Big Rock Point, Zion, Limerick, Grand Gulf, and Arkansas Nuclear One. The first three were the utility sponsored studies publicly available at the time of project initiation while the other two were deemed representative of the NRC's RSSMAP and IREP programs respectively. The results of PRA studies are usually expressed in terms of core melt frequencies, radionuclide release frequencies, and frequencies of occurrence of different reactor accident consequences (e.g., early and latent fatalities) depending on the level of PRA. These subjects are prominently addressed in this paper. One of the results of a PRA study is identification of a relatively small number of accident sequences that represent the dominant contributors to core melt. An analysis of the salient features of the dominant accident sequences from eleven PRA's yielded a characterization of accident sequence categories discussed at some length. Impact of external events is discussed very briefly. Next to an explicit quantification of public risk or core melt frequency, the identification of specific safety concerns and the evaluation of possible solutions to implement risk management are probably the best recognized and most widely used applications of PRA. Several illustrative examples are briefly discussed. Human interactions are extremely important contributors to safety and reliability of the plants. A review of PRA studies concluded that it was necessary to account for five types of human interactions; some of which may mitigate while others may exacerbate an accident sequence.     

美国未成年人前科记录封存探析

自少年法院创设伊始,美国少年司法长期秉承保密性原则而对未成年人前科记录予以封存,以避免给未成年人带来污名化后果。然而,随着各州未成年人前科记录封存呈松动趋势,部分原先严格保密并限制公布于众的前科记录,除了可向执法及司法部门开放外,亦可在一定条件下向被害人、学校及媒体开放。与此同时,依移送法律而从少年法院移送至刑事(成人)法院的未成年人,其先前少年法院记录亦可作为后者加重刑罚的考量因素之一。

我国近二十五年来的学前教育研究进展——以《学前教育研究》杂志发文的可视化分析为依据

以《学前教育研究》近25年（1994—2018）刊登的文章作为分析样本,通过Cite Space绘制有关学前教育文献的关键词共现时区视图、关键词共现知识图谱、高频发文机构、发文作者统计表等,并且根据CNKI文献计量可视化分析软件绘制1994-2018年期间我国学前教育发文量折线图。分析发现,我国学前教育研究经历了持续快速发展、艰难曲折发展、得到一定发展、取得较大进步以及快速发展五个阶段;经历了表层研究阶段、专业性有了一定改善、专业化倾向进一步加强、专业化水平大幅度提升四个阶段;南师大、北师大以及华东师大是学前教育领域的高频发文机构,是该领域专业发展的中坚力量;冯晓霞、庞丽娟、杨晓萍、刘焱、皮军功等是高频核心作者,是我国学前教育研究的主要标志;研究的热点主题主要有：幼儿教师研究、幼儿学习与发展研究、幼儿园课程研究、幼儿园管理研究、幼儿园教学研究、城乡幼儿教育研究、学前教育专业研究、学前家庭教育研究以及早期阅读研究。     

国内专门用途英语研究述评(2000—2021年)——基于CiteSpace的可视化分析

借助文献计量工具CiteSpace对2000—2021年间CNKI收录的中文核心期刊、CSSCI来源期刊及辑刊《中国ESP研究》发表的专门用途英语（ESP）相关论文进行可视化梳理,探究国内ESP研究的整体趋势、内容和特点,旨在为相关研究的进一步开展提供参考和启示。研究结果表明：21世纪以来国内ESP研究整体呈上升趋势,热点主题涵盖ESP本体研究、相关教材研究、相关理论与教学研究等;语言学和社会语言学构成了ESP研究的主体领域,跨学科特征虽有所凸显,但研究深度和广度仍有待拓展;从历时发展来看,ESP研究曾涌现商务英语、专业英语、英语教学等多个前沿领域,其中学术写作教学研究是近年关注焦点。     

汉阳陵新出土印章封泥考述

汉承秦制,汉代的印章封泥是在继承秦代印章封泥制度的基础上发展起来的,汉代曾出现了中国印文化史上的高峰。20世纪80年代初以来,陕西汉阳陵区和阳陵邑先后出土了大量的汉代印章封泥,为中国印制与官制、印章与陵园建筑等方面的研究,提供了难得的实物资料,开辟了新的研究途径。     

地方政府创新研究的热点主题与理论前瞻

地方政府创新是我国重要的政治现象与理论研究的热点议题。对国内涉及地方政府创新的研究文献进行系统梳理,运用文献计量方法,结合因子分析、聚类分析和社会网络分析之后,可归纳出地方政府创新研究的四个热点主题:地方政府创新的基本理论研究、地方政府创新与政府改革研究、地方政府创新与政府绩效研究、地方政府创新中的动因研究。据此可提出此研究的前沿性领域:政府创新管理的理论研究、地方政府创新的持续力研究、地方政府创新的制度化研究、公共服务创新研究。在区分显性公共需求和隐性公共需求的基础上,可得出创新性公共服务与回应性公共服务的分析框架。

The spatial distribution of smoking violations on a no-smoking campus: Implications for prevention

ABSTRACT

Objective: The present study extends research on campus smoking bans by examining where smokers are violating the policy at a large university in the southeastern region of the United States. Participants: The data collection was conducted by one graduate student from the university in August of 2014. Methods: A global positioning system device was used to collect the geo-coordinates of littered cigarette butts as a proxy measure for smoking violations. Results: A hot spot analysis found a number of spatial concentrations on campus, largely around classroom and administrative buildings along with parking lots and garages. Conclusions: The implications of such findings can direct enforcement to target these areas in order to reduce offenses and fulfill the initial goals of policy-makers and university administrators who support smoke-free campuses.
