Vaginal births after caesarean: What does Google think about it?

AimVaginal birth after caesarean (VBAC) is a relatively safe alternative to repeat caesarean birth in the proper context. This important decision to undergo an elective caesarean versus VBAC is ultimately a decision of the mother. The purpose of our study was to assess the quality of online information in relation to VBAC collected using the most common search engine: Google.MethodsThe 10 most common hit sites for the keywords “VBAC” and “Vaginal birth after caesarean” were evaluated using the search engine Google. The quality of websites was rated based on the Silberg scale for accountability, the modified Abbott's criteria for presentation and the SMOG index for readability. The content of each website was compared to the Society of Obstetricians and Gynecologists of Canada (SOGC) guidelines for VBAC.Findings13 out of 20 identified websites met the adequate criteria for accountability, with 85% of the websites indicating authorship. 11 websites were deemed aesthetically agreeable. The target audience, assessed by the readability score, was notably above the non-medical population with an average SMOG index score of 14.75. Only half of the websites contained recommendations, as detailed by the SOGC guidelines.ConclusionAlmost all sites target a higher academic level, making it beyond the comprehension of the general population. Woman friendly web-assessment tools should be provided to enable pregnant women to take an active role in their decision making.     

A New Methodology for Before–After Safety Assessment Using Survival Analysis and Longitudinal Data

The widely used empirical Bayes (EB) and full Bayes (FB) methods for before–after safety assessment are sometimes limited because of the extensive data needs from additional reference sites. To address this issue, this study proposes a novel before–after safety evaluation methodology based on survival analysis and longitudinal data as an alternative to the EB/FB method. A Bayesian survival analysis (SARE) model with a random effect term to address the unobserved heterogeneity across sites is developed. The proposed survival analysis method is validated through a simulation study before its application. Subsequently, the SARE model is developed in a case study to evaluate the safety effectiveness of a recent red‐light‐running photo enforcement program in New Jersey. As demonstrated in the simulation and the case study, the survival analysis can provide valid estimates using only data from treated sites, and thus its results will not be affected by the selection of defective or insufficient reference sites. In addition, the proposed approach can take into account the censored data generated due to the transition from the before period to the after period, which has not been previously explored in the literature. Using individual crashes as units of analysis, survival analysis can incorporate longitudinal covariates such as the traffic volume and weather variation, and thus can explicitly account for the potential temporal heterogeneity.

《文心雕龙·神思》创作要义新绎

刘勰《文心雕龙·神思》篇是一篇专论艺术构思与想象的著名论文。其“神与物游”说,实即形象地阐明了“心物交融”的过程,开启了形象思维理论的先声;而形象思维的结晶便是“意象”,即“人心营造之象”,作者要像“窥意象而运斤”的“独照之匠”那样,迅摄意象,运笔于纸。而意象的酝酿与定型,其必不可少的前提又“贵在虚静”。“虚静”是对创作之前的作者必须保持境静与心静的双重要求。

论京剧的雅化及其鼎盛

文章论述了京剧在 2 0世纪 30年代达到鼎盛阶段的内外部原因。在其内部原因上 ,作者以其研究古代文学史时所提出的“原生态式的把握方式”来观察这一段京剧史 ,从而对这一段京剧史的发展作了新的勾勒 :艺术块团之形成、相互间的争锋、浮沉以及名号形成的种种情况。在其外部原因上 ,论述了京剧是如何从回应“五四”新文化运动的批评以及如何从向话剧的学习中受益的。 30年代新文化界对于当时京剧的雅化是批判的 ,作者则对此取肯定态度。最后还说明了 ,当京剧出国演出时 ,它的许多曾受“五四”新文化运动批判的特点 ,却受到了国外艺术家的肯定 ,中国的京剧艺术家们也更加开拓了视野 :由此勾勒出京剧发展过程中的一个大的回旋
