The relatively high failure rates, with important consequences in many cases, suggest that the implicitly acceptable risk levels corresponding to temporary civil engineering structures and activities might exceed the bounds of normally acceptable levels associated with different societal activities. Among other reasons, this may be attributed to the lack of a rational approach for the assessment of risks associated with the different technologies supporting these activities in general, and for structures in particular. There is a need for establishing appropriate target reliability levels for structures under temporary use taking into account specific circumstances such as reduced risk exposure times. This issue is being addressed in this article. Acceptance criteria for building-structure-related risks to persons obtained in prior studies are adapted to the special circumstances of nonpermanent risk exposure. Thereby, the general principle followed is to maintain the same risk levels per time unit as for permanently occupied buildings. The adaptation is based on the statistical annual fatality rate, a life safety risk metric that allows for a consistent comparison of risks across different societal activities and technologies. It is shown that the target reliability indices taking account of the temporary use of buildings might be significantly higher than the values suggested for permanently used structures. 相似文献

The aim of this research was to adapt and validate the Concern with Acting Prejudiced (CAP) scale for a Spanish sample. This measure evaluates concern about appearing prejudiced to others or oneself and the motivation not to deviate from personal egalitarian standards. First, we completed the translation and an item content validity analysis. Then, in Study 1 (N = 198), we conducted an exploratory factor analysis. In Study 2 (N = 383), we conducted a confirmatory analysis of the unifactorial structure of the Spanish version of the scale and examined its validity. In Study 3 (N = 89), we explored the moderating role of participants’ concern with acting prejudiced in the relation between implicit prejudice and explicit prejudice. The results confirmed the unifactorial structure of the scale, its appropriate psychometric properties and its predictive validity. Moreover, we confirmed that the CAP moderated the relation between implicit and explicit prejudice. In participants with a low concern with acting prejudiced, implicit prejudice was positively related with modern prejudice; in participants with a high concern with acting prejudiced, these variables were not related. 相似文献

Qualified competences in social science and humanities are required across the various deliverables of the intergovernmental science-policy platform on biodiversity and ecosystem services (IPBES) in order to fully address the objectives of IPBES. Building integrative approaches has long been acknowledged as a scientific challenge. Hence, new paths have to be forged, including revisiting basic ontological and epistemological considerations, such as how we understand the world, what knowledge is, and the role of science. Constructive interdisciplinary dialogues in IPBES supports the development of innovative frames and terminologies. One example is the evolution from the Millennium Ecosystem Assessment ecosystem service framework to the Nature’s Contributions to People classification now applied in IPBES assessments. IPBES is still in a learning phase and critical examination of what is accomplished this far is useful when refining ongoing modes of work and in long-term strategic considerations. 相似文献

王国维用“意境”“境界”等概念建构起自己的美学体系。他认为作为抒情文学的词作必须有作者的真情实感蕴藏于内,“真情”是“境界”说的重要组成部分。出于对“真情”的看重,王国维着力于对元剧的研究,从戏剧艺术的角度,他对元剧十分鄙视,但从文辞的角度,他对元剧十分欣赏。王国维称元曲为“活文学”,与元曲作者蕴于其中的“真情”有莫大关系。王国维对元曲的研究基本延续了治词的角度和观点,论曲仍以“真情”为首要标准。不同之处在于,“当行”也是他的“本色”观的组成部分,是其“本色”观比“意境”说在理论范围上更为广阔之处。相比较而言,吴梅的“本色”观亦注重“真情”,对作品的评论,他更多的是从排场角度分析、评价作品。对作品的用字,吴梅亦崇尚自然,同时又有所保留。 相似文献

Robust Bayesian nonlinear mixed‐effects modeling of time to positivity in tuberculosis trials 下载免费PDF全文
Early phase 2 tuberculosis (TB) trials are conducted to characterize the early bactericidal activity (EBA) of anti‐TB drugs. The EBA of anti‐TB drugs has conventionally been calculated as the rate of decline in colony forming unit (CFU) count during the first 14 days of treatment. The measurement of CFU count, however, is expensive and prone to contamination. Alternatively to CFU count, time to positivity (TTP), which is a potential biomarker for long‐term efficacy of anti‐TB drugs, can be used to characterize EBA. The current Bayesian nonlinear mixed‐effects (NLME) regression model for TTP data, however, lacks robustness to gross outliers that often are present in the data. The conventional way of handling such outliers involves their identification by visual inspection and subsequent exclusion from the analysis. However, this process can be questioned because of its subjective nature. For this reason, we fitted robust versions of the Bayesian nonlinear mixed‐effects regression model to a wide range of TTP datasets. The performance of the explored models was assessed through model comparison statistics and a simulation study. We conclude that fitting a robust model to TTP data obviates the need for explicit identification and subsequent “deletion” of outliers but ensures that gross outliers exert no undue influence on model fits. We recommend that the current practice of fitting conventional normal theory models be abandoned in favor of fitting robust models to TTP data. 相似文献

In this paper, we use longitudinal data to investigate how parental death and divorce influence young women’s own experience of divorce in Malawi, a setting where women marry relatively early and unions are fragile. We find that maternal death and parental divorce are positively associated with divorce for young women but, after controlling for socio-demographic and marital characteristics, only the association with maternal death remains statistically significant. Maternal and paternal death are both strongly associated with women’s post-divorce living arrangements, which in turn affects their material well-being. This finding suggests that divorcing at a young age shapes the subsequent life chances of women; although some women return to their parental home and may have the opportunity to reset the transition to adulthood, other women begin their 20s as head of their own household and with considerable material disadvantage. 相似文献

为了让习近平新时代中国特色社会主义思想“进教材、进课堂、进头脑”,需要从方式、方法层面进行分析。在深耕教材的基础上,发现2018版《马克思主义基本原理概论》教材在融入习思想时,依据不同内容主要采取了文献参考式、引入说明式、说明原理式、补充创新式、替代更新式等方法。为有效做好教材体系向教学体系转换,针对教材中对习思想融入的不同方式,可以因内容分别或组合选择活动拓展法、课前一语法、习近平话语中心式教学法、问题式教学法、案例教学法等。在转化过程中,在方法论上必须坚持马克思主义辩证法,具体问题具体分析,做到转化有法但无定法;在转化的内容和方法的关系上,必须坚持内容和方法的有机统一,从习思想和教材整体视角审视转化,处理好整体与部分的关系;在思政课的价值引领方面,必须处理好真理与价值的关系,把转化最终落脚于价值转化,使习思想真正入脑、入心。 相似文献

Objective: This study examines the health insurance literacy, or the ability to use health insurance effectively, of college students. Participants: A total of 455 students from a large, public university completed an online questionnaire in November 2016. Methods: A questionnaire examined students’ knowledge of commonly encountered health insurance terms and ability to apply that knowledge to determine cost-sharing in a clinical setting. Results: The majority of students were able to correctly identify the most commonly encountered terms, but could not identify terms related to plan types and options. Eighty-eight percent of students could not determine their cost-sharing for two presented scenarios. Approximately half of the students indicated they had been confused about their health insurance plan, with one-quarter of students stopping or delaying medical care due to confusion. Conclusions: Outreach and education for students should target specific deficits in knowledge such as those identified in this study. 相似文献

习近平总书记在2019年3月18日主持召开全国学校思想政治理论座谈会并发表重要讲话,即“3·18”讲话。在“3·18”讲
话中,习近平总书记不仅强调了新时代我们“为什么”要办好思想政治理论课,而且明确回答了新时代我们要办“什么样”的思
想政治理论课和“如何办好”思想政治理论课等一系列重大问题。实践表明, “3·18”讲话是党中央新时代办好思想政治理论课
的重要遵循。在该讲话发表一周年之际,重温这一讲话具有重要理论和现实意义。 相似文献

我国宪法赋予了公民用自己的民族语言文字参加诉讼的权利,目的在于实现民族平等、促进民族团结、禁止民族分裂、保护中华民族语言文化的多样性,进而提高我国的文化软实力。通过调查民族语言文字诉讼司法实务,发现当前存在着少数民族语言文字诉讼程序混乱、不符合诉讼原理等问题,不利于民族语言文字诉讼权利的实现。究其原因,在于该诉讼制度缺乏程序保障。为了确保民族语言文字诉讼权利的有效实现,应设立“民汉双语诉讼规则”,以为司法机关提供统一的操作规范。民汉双语诉讼规则应该明确民汉双语诉讼的概念、类型以及民族语言文字诉讼权利的内容,并且根据不同诉讼类型有针对性地设置审判语言与诉讼语言的适用规则。 相似文献
