简介：【摘要】高校图书馆馆藏设计是建设图书馆最基本工作，与获取馆藏相关的工作是馆藏设计的关键内容，采购工作的质量和水平直接影响到图书馆馆藏的建设。国外高校图书馆对馆藏发展政策的认可度很高，政策内容相对成熟和完善。但是，我国只有少数高校图书馆制定了馆藏发展政策，其中馆藏采购政策的内容过于理论化，并且效率低，阻碍了其实际应用。本文的主要目标是分析三所国外大学图书馆和一所国内高校图书馆的藏书的政策，以及公共采购领域的详细原则、指南和工作标准。通过比较和学习国外三所高校图书馆馆藏发展政策，对国内高校图书馆馆藏建设进行启示，建立我国高校图书馆战略发展计划。

简介：AbstractBiosafety equipment is the key barrier enabling high containment laboratories to handle high risk agents that may cause serious and potentially lethal infections. This perspective thoroughly analyzes the development of many kinds of key biosafety technologies, and equipment for protection of laboratory workers and for high containment laboratory facilities in China. Over more than ten years of rapid development, China has had remarkable achievements in key biosafety technologies and equipment in high containment laboratories. These technologies basically meet the needs of high containment laboratories construction in China. Furthermore, according to the current global situation regarding the prevention and control of infectious diseases and the technical development level of biosafety equipment, this paper proposes targeted suggestions and notes that China still needs to increase investment in scientific research to provide further technical and equipment support enabling us to build a community with a bright future in terms of human biosafety.

简介：AbstractImportance:Parents take the lead in parent-child interactions and their emotion regulation ability and empathy during parenting may be associated with children’s emotional/behavioral problems. However, the specific mechanisms underlying these associations remain unclear.Objective:The present study aimed to explore the effect of parental empathy and emotional regulation on social competence and emotional/behavioral problems in school-age children.Methods:A questionnaire-based survey was conducted with 274 parents of 8-11-year-old children using Achenbach’s Child Behavior Checklist, the Emotion Regulation Questionnaire, and the Questionnaire of Cognitive and Affective Empathy.Results:Children with emotional/behavioral problems (n = 37) had relatively lower social competence than children in a matched control group (n = 37). Compared with the parents of children in the control group, parents of children with emotional/behavioral problems had significantly lower cognitive empathy scores, mainly manifested by low perspective-taking and online simulation abilities. Mediation analysis showed that parental cognitive empathy had an indirect effect on children’s emotional/behavioral problems through children’s social competence.Interpretation:Parental empathy may have a subtle influence on the social competence of school-aged children, which further affects the severity of children’s emotional/behavioral problems.

简介：AbstractBackground:Soil-transmitted helminthiases (STH) are part of the group of neglected tropical diseases traditionally treated with preventive chemotherapy interventions. In recent years, drug donations have been essential to expanding preventive chemotherapy and achieving progressive control of morbidity from STH. This study aims to evaluate the need for anthelminthic medicines during 2020–2030.Methods:To estimate the need for anthelminthic medicines, we considered three different scenarios: (1) the control programmes continues to expand coverage and maintains the frequency of drug administration established at baseline; (2) the programmes continues to expand coverage but adapts the frequency of drug administration when the STH prevalence is reduced and (3) the STH programme becomes self-sustainable in some endemic countries.Results:We estimate that the number of anthelmintic medicines needed to treat school-aged children will increase by 40% by 2025 and by 52% by 2030 if countries do not change the frequency of preventive chemotherapy (scenario 1); that the number of tablets needed will reduce by 32.4% by 2025 and by 49.1% in 2030 if endemic countries reduce the frequency of preventive chemotherapy (scenario 2); and drug donations could be reduced by 54.4% by 2025 and 74.4% by 2030 if some endemic countries could become independent in drug procurement (scenario 3).Conclusions:The number of anthelmintic medicines needed to achieve elimination of morbidity due to STH in school-aged children will decline during 2020–2030. The decline will be substantial if a number of "upper-middle income" countries in which STH are endemic procure, as expected, anthelminthic medicines independently.
