Evaluation of an intervention supporting breastfeeding among late-preterm infants during in-hospital stay

BackgroundLate-preterm infants show lower breastfeeding rates when compared with term infants. Current practice is to keep them in low-risk wards where clinical guidelines to support breastfeeding are well established for term infants but can be insufficient for late-preterm.ObjectiveThe aim of this study was to evaluate an intervention supporting breastfeeding among late-preterm infants in a maternity service in the Basque Country, Spain.MethodsThe intervention was designed to promote parents’ education and involvement, provide a multidisciplinary approach and decision-making, and avoid separation of the mother-infant dyad. A quasi-experimental study was conducted with a control (n = 212) and an intervention group (n = 161). Data was collected from clinical records from November 2012 to January 2015. Feeding rate at discharge, breast-pump use, incidence of morbidities, infant weight loss and hospital stay length were compared between the two groups.ResultsInfants in the control group were 50.7% exclusive breastfeeding, 37.8% breastfeeding, and, 11.5% formula feeding at discharge, whereas in the intervention group, frequencies were 68.4%, 25.9%, and 5.7%, respectively (p = 0.002). Mothers in the intervention group were 2.66 times more likely to use the breast-pump after almost all or all feeds and 2.09 times more likely to exclusively breastfeed at discharge. There were no significant differences in morbidities and infant weight loss between groups. Hospital stay was longer for infants who required phototherapy in the intervention group (p = 0.009).ConclusionThe intervention resulted in a higher breastfeeding rate at discharge. Interventions aimed to provide specific support among late-pretem infants in maternity services are effective.     

Whither Risk Assessment: New Challenges and Opportunities a Third of a Century After the Red Book

Six multi‐decade‐long members of SRA reflect on the 1983 Red Book in order to examine the evolving relationship between risk assessment and risk management; the diffusion of risk assessment practice to risk areas such as homeland security and transportation; the quality of chemical risk databases; challenges from other groups to elements at the core of risk assessment practice; and our collective efforts to communicate risk assessment to a diverse set of critical groups that do not understand risk, risk assessment, or many other risk‐related issues. The authors reflect on the 10 recommendations in the Red Book and present several pressing challenges for risk assessment practitioners.     

明代中后期的撒里畏兀儿

从嘉靖七年（１５２８年）明朝兵部尚书王琼总制三边、安辑东迁后的 撒里畏兀儿诸部,至明、清之交。这一时期,撒里畏兀儿失去了自"黄头田纥"以 来的左右一方的相对独立局面,因受制于人而动荡不安、艰难求生,对今日裕固 族社会产生了重大影响。     

王国维悲剧思想与悲情意识探源——论《红楼梦评论》对西学、佛学和老庄思想的熔铸

王国维受叔本华悲观主义哲学的影响,在《红楼梦评论》、《人间词话》和《宋元戏曲考》等著作中均体现了其悲剧思想对西学、佛学和老庄的熔铸性,开创中国美学研究之先河。王国维悲情思想主要体现在三方面:一是与叔本华悲剧精神的互通;二是认同佛家的涅槃,和叔本华倡导的解脱殊途同归;三是包涵老庄的"无为"、"无我"等传统底蕴。重新认识王国维的悲剧思想和悲情意识的源头,理解王国维对中西印等文化传统的沟通、合流、熔铸,才能理解和把握王国维在美学研究领域的大创制。     

新红学的开端,新典范的创始:王国维的红学研究述论--现代学人的红学研究综论之一

王国维在《红楼梦评论》中所提出的问题不仅蕴含着新锐的思想光芒,同时具有鲜明的学术启示意义,如“解脱”说、“悲剧”说、“伦理学上之价值与美学上之价值合一”说等。20世纪初期提出的这些崭新命题,具有立意新、方法新、见解新的特征,为中国小说研究的现代学术范式建立做出了可贵的学术贡献。同时,《红楼梦评论》引入叔本华哲学所建立的《红楼梦》研究的新范式,是王国维在红学批评方面建立的桥头堡,仍有待继续前行,精进日新。     

校本课程“教育文艺”教学改革刍议——《红楼梦》大观园题咏的教育启示

大观园题咏是贾政主导众清客协力配合对贾宝玉实施的一次成功的教育实验。它给予我们“教育文艺”校本课程的启示是多方面的：教学内容体系建构上要丰富多彩，更加注重应用性；教学方法手段上要多样化，尤其重在启发参与；教学考核评价上要多元开放，注重过程和实践。     

角色理论视野下医院志愿者发展定位剖析

角色理论通过对角色行为改变和及其原因的研究,解释人类社会行为的改变。在角色理论分析的视野中,医院志愿者属于自致角色、规定性角色、表现性角色,从而决定了其规范性、无偿性、非功利性特征。在角色采择和角色扮演过程中,个人只有具备相应的认知能力和自知能力,并衍生成为合格的角色技能,持有正确的角色期待,方能顺利完成医院志愿者角色行为。为防止和纠正志愿者对于自身归属医方还是患方产生困惑、不了解志愿服务内容、对志愿服务产生负担思想、作出不称职行为等角色失调情况,可通过正确定位医院志愿者角色、清晰明确医院志愿者角色行为标准、合理安排志愿服务日程、及时疏导志愿者负面情绪、建立医院志愿者激励机制、提升志愿者自我价值认知等途径以完善医院志愿者角色塑造,充分发挥角色功效。     

A general class of test statistics for Van Valen's Red Queen hypothesis

Van Valen's Red Queen hypothesis states that within a homogeneous taxonomic group the age is statistically independent of the rate of extinction. The case of the Red Queen hypothesis being addressed here is when the homogeneous taxonomic group is a group of similar species. Since Van Valen's work, various statistical approaches have been used to address the relationship between taxon age and the rate of extinction. We propose a general class of test statistics that can be used to test for the effect of age on the rate of extinction. These test statistics allow for a varying background rate of extinction and attempt to remove the effects of other covariates when assessing the effect of age on extinction. No model is assumed for the covariate effects. Instead we control for covariate effects by pairing or grouping together similar species. Simulations are used to compare the power of the statistics. We apply the test statistics to data on Foram extinctions and find that age has a positive effect on the rate of extinction. A derivation of the null distribution of one of the test statistics is provided in the supplementary material.     

Red states,blue states: How well do the recent national election labels capture state political and policy differences?

The alleged polarization between the so-called red (Republican) and blue (Democratic) states during the presidential elections has been examined using only voter surveys. Focusing on the recent thirteen national elections from 1964 to 2012, we examine social, political, institutional, and policy indicators of the 50 American states to (1) gauge the extent to which national election results reflect significant policy and political differences between the red and blue states and (2) to assess the explanatory power of the dichotomous red–blue label relative to a continuous variable of “redness” or “blueness” by the percentage of votes received. We find substantial political and some moderate social differences between red and blue states but fewer institutional and policy differences than one would expect if there were actually deep divisions between the states. We find that the red–blue state distinction performs well when compared to the explanatory power of the more precise redness or blueness of a state.
