胡适与民国时期安徽大学的初创

作为一位皖籍著名学者,胡适并不仅仅关注中国和世界,他同样十分关注家乡安徽的教育文化事业.1921年8月,胡适首先发出筹建安徽大学的呼吁.之后,他对推动安徽大学的筹建起了重要和积极的作用.1928年4月安徽大学成立后,他曾是安徽大学首位校长的主要人选,并且与安徽大学最初几位校长关系密切,对他们有重要影响.

Child protection decision-making

The effects of interagency collaboration on risk assessment in child protection practice were analysed in respect of the decision-making processes in child death inquiries. Universal features in the assessment of risk as identified in psychological literature were applied; in particular, the concepts of ‘groupthink’, the ‘certainty effect’ and ‘group polarization’. It is suggested that case conference decisions are inherently more risky than those taken by professionals with individual responsibility because of the way in which cases are framed in terms of losses.

高校图书馆与新时期信息素质教育

信息是当今社会最重要的资源之一,人们对信息的需求正呈现出多层次、多样化的形式。在新的信息环境下,高校图书馆应与时俱进地积极转变观念,拓展教学内容,规范相关要求,在信息素质教育中作出突出的贡献。     

论褚伯秀《南华真经义海纂微》注庄“视脚”

褚伯秀的《南华真经义海纂微》纂集了从西晋的郭象至南宋的林希逸等十三家注,是现存最早的《庄子》集注作品。该书纂集众注,断以己意;兼顾音训,注重义理;擘肌分理,唯务折衷,在庄学研究史上意义重大。褚伯秀身为道教中人,却以独特之“视脚”涵摄了儒释道诸多视角,努力克服以偏概全、挂一漏万的弊端,他的这种通化的根性值得我们重视。     

Issue Information

In 2017, the number of applications for care orders in England and Wales was the highest ever recorded at 14,207. This is a significant factor, contributing to the rise in the number of children who are looked after, which is at the highest level since 1985. The authors reflect on the recently published Care Crisis Review 2018, a sector‐led review, which examines the reasons for the rise in care proceedings and the number of children in care. The review sought to identify changes to policy and practice within local authorities and the family justice system, in an attempt to divert cases away from the family courts and to reduce the number of children in care, where it is safe to do so. Whilst the legislative framework is largely effective and the system generally works well, there is insufficient funding and resources to meet the needs of children and their families when they seek help, regardless of whether this is at an early stage or when they are in crisis and most in need of care and protection.     

中国城市趋同化及其治理

中国城市现代化过程中,必然产生的城市趋同化现象,造成城市资源巨额浪费、城市间恶性竞争、公共利益受到侵蚀,加之政治经济转型期的特殊社会背景、管理体制缺陷及特有的“失误放大效应”,使其负面效应不断加剧,引发社会矛盾加剧,威胁城市和谐健康发展。在正确认识城市趋同的正面意义与负面影响的基础上,立足于城市特色和比较优势,理顺城市管理中各方利益关系,以建立城市创新机制为核心,营造积极和谐的管理文化,建立科学的评估评价标准体系和城市管理体系,促使城市趋同的边际收益最大化,促进城市的良性发展。     

Graphical representation of survival curves in the presence of time-dependent categorical covariates with application to liver transplantation

Graphical representation of survival curves is often used to illustrate associations between exposures and time-to-event outcomes. However, when exposures are time-dependent, calculation of survival probabilities is not straightforward. Our aim was to develop a method to estimate time-dependent survival probabilities and represent them graphically. Cox models with time-dependent indicators to represent state changes were fitted, and survival probabilities were plotted using pre-specified times of state changes. Time-varying hazard ratios for the state change were also explored. The method was applied to data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL). Survival curves showing a ‘split’ at a pre-specified time t allow for the qualitative comparison of survival probabilities between patients with similar baseline covariates who do and do not experience a state change at time t. Time since state change interactions can be visually represented to reflect changing hazard ratios over time. A2ALL study results showed differences in survival probabilities among those who did not receive a transplant, received a living donor transplant, and received a deceased donor transplant. These graphical representations of survival curves with time-dependent indicators improve upon previous methods and allow for clinically meaningful interpretation.     

Demographic differences in response rates for PHQ9 in a university student population

Objective: To examine differences in complete response rates for depression screening questions based on demographic characteristics. Methods: Cross-sectional study examining associations between demographic characteristics and completely responding depression-screening questions. Participants: “Healthy Minds Study” data, collected in a public University in February 2016, where 7,326 students participated. Results: women (AOR: 0.69; 95% CI =0.57–0.83) and gay/lesbian students (AOR: 0.24; 95% CI =0.10–0.60) had better complete response rates. Non-US (AOR: 1.46; 95% CI =1.03–2.07), black (AOR: 3.32; 95% CI =1.92–5.77), and Middle-Eastern students (AOR: 3.73; 95% CI =1.73–8.02) had lower complete response rates. Conclusions: Our study shows sex, gender, citizenship, and race categories have significant differences in complete response rates for the outcome. Our findings have several implications; including recognizing interventions for depression based on responders may not target those that tend to be “partial-responders”. Efforts in survey design, recruiting and completion of surveys should be maximized.
