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.     

"道学"与汤显祖的文体选择

汤显祖的思想相当驳杂,“道学”是最值得重视的因素。“道学”形而上的内在精神超越,赋予了汤氏独特的“思想者”气质,并进而影响他的文体选择。其古文理想和曲体价值观,均显示出重道德理性的传统“杂文学”观念在晚明时期的回潮。

从分析我国地方政府制度创新的动因入手，着重从三个方面讨论了我国地方政府制度创新的路径，即地方政府应履行自己的产权职能，以制度创新促进产权的多元化，并通过产权保护，解决微观主体的动力激励问题；以制度化规范中央与地方的制度创新关系；退出市场职能领域，实现制度创新的范式转换。     

我国十二生肖文化探源

十二生肖是一种颇具内涵的文化现象，在我国已有悠久的历史。其特点是以十二种动物配十二地支，以人之生年定所属动物。我国远古的图腾崇拜是十二生肖的滥觞，而干支的创制与中华民族的多元一体则是十二生肖形成的基础.     

Joint tests of non-nested models and general error specifications

This paper is concerned with joint tests of non-nested models and simultaneous departures from homoskedasticity, serial independence and normality of the disturbance terms. Locally equivalent alternative models are used to construct joint tests since they provide a convenient way to incorporate more than one type of departure from the classical conditions. The joint tests represent a simple asymptotic solution to the “pre-testing” problem in the context of non-nested linear regression models. Our simulation results indicate that the proposed tests have good finite sample properties.

我国农村人口出生性别比偏高的动力机制研究

B超的滥用、强烈的男孩偏好以及对非法流产行为监控的失效共同构成我国出生性别比偏高的充要条件,三者中任一条件不满足都不可能出现出生性别比偏高。尽管B超发明和滥用前出生性别比并没有异常,但也不能说出生性别比偏高与受教育水平、传统文化等因素无关。事实上,这些因素通过影响男孩偏好和B超的可获得性而影响出生性别比。由此出发,促进出生性别比回复正常,短期内应标本兼治,以治标为主———坚决禁止B超的滥用,关键是加强立法和管理;长期内则必须治本———消除男孩偏好,关键是加速农村城市化。
