高校实验室档案规范化管理探讨

高校实验室档案管理是实验管理中不可缺少的一部分,直接反映高校的教学质量、科研及管理水平。建立和完善高校实验室档案,将其纳入高校管理的基础性、日常性工作,进行科学化、规范化管理,是提升高等学校办学水平和质量的必要前提。本文就高校实验室档案管理的范畴、高校实验室档案规范化管理的重要性及具体措施进行了探讨。     

强身合剂对大鼠血液、生化指标及脏器系数的比较研究

目的:强身合剂与生理盐水对大鼠血液、生化值及内脏器官(心、肝、脾、肺、肾上腺、胸腺)重量的比较研究.方法:将SD大鼠60只分成3组,给强身合剂10.0和20.0g/kg(指含生药量)剂量,对照组给等量生理盐水,连续给药31天,每周称体重一次,给药结束时采血测定血液指标和生化指标.解剖后,用电子天平称各个脏器器官的重量,并计算脏器系数.结果:SD大鼠的血红蛋白(HGB)、红细胞计数(RBC)、白细胞计数(WBC)、与生理盐水组比较无显著性差异(P＞0.05);血清生化指标天冬氨酸氨基转移酶(AST)、ALT、Cr、BUN与生理盐水组比较无显著性差异(P＞0.05);脏器系数给药组与生理盐水组比较无显著性差异(P＞0.05).结论:强身合剂10.0、20.0g/kg组连续给药31天,其血液血清生化指标及胜器系数与给生理盐水组比较均无显著差异.

基于知识媒体的建构主义学习环境设计

学习环境设计是教学理论领域的两大主题之一。随着知识媒体概念的提出及不断发展,它对学习环境的影响也越来越明显。主要表现在呈现教学信息、构造仿真情境、创建虚拟学习空间、丰富的信息资源和学生评估等几个方面。     

优化科学中心对ＳＴＥＭ 教育的贡献

STEM教育能够发展学科知识和智力技能,这对于推动创新从而应对全球经济、社会和环境挑战是十分重要的。在全球化和数字技术颠覆传统科学教育的情况下,STEM教育的能力也是年轻人掌控就业主动权的关键。科学中心在直接实施STEM教育以及间接提升社区对STEM重要性认识的方面发挥着重要作用。本文主要阐述三个问题:亚太地区国家实行STEM教育的现状如何？新的就业环境如何影响年轻人对STEM教育能力方面的预期和他们的要求是什么？科学中心如何优化其对STEM的贡献？     

南充市同域分布的白腰文鸟白颊噪鹛和白头鹎巢和巢材比较研究

2011年2—9月对四川省南充市西山风景区人工林白腰文鸟、白颊噪鹛和白头鹎3种同域分布鸟类鸟巢及巢材进行了相关研究．结果表明：在该研究区域内,3种鸟的总营巢数为19个．鸟巢参数测量结果显示,3种鸟巢离地高、巢干重、外长半径、外短半径、内短半径之间的差异不显著,巢深、巢高2种指标在自腰文鸟和另2种鸟巢之间存在的差异达到极显著水平,而内长半径的极显著性差异出现在白腰文鸟和白颊噪鹛两种鸟之间;3种鸟巢均可明显分为3层,固定层、沥水层和调温层;3种鸟的巢材选择较为广泛,白腰文鸟、白颊噪鹛和白头鹎巢材选择种类依次为16种、27种和25种,分属禾本科、莎草科、樟科、桑科、十字花科、柏科、苔藓植物门石竹亚纲、苋科、葡萄科、木犀科、芸香科、蓼科和豆科植物．其中：3种鸟共同选择的巢材有白茅、风尾竹叶、荩草、天竺桂树叶、矛叶荩草、小叶榕气生根、薄菜、侧柏、构树叶、獯草、慈竹叶和密序野古草等12种植物;白腰文鸟、白颊噪鹛和白头鹎各自选择最多的巢材依次是小糠草、枇杷树叶和荩草,占其各自干重的比例为43．68％、13．98％和14．05％．     

Facilitators and Barriers to Movement Integration in Elementary Classrooms: A Systematic Review

Purpose: A systematic review was conducted to identify facilitators and barriers to movement integration (MI) in elementary school classrooms. Method: Online databases (Educational Resources Information Center, Google Scholar, PsycINFO, and PubMed) served as data sources for the study. Following the PRISMA guidelines, relevant published research on MI was identified and screened for inclusion in a qualitative synthesis. Content analysis of the included articles (N = 28) was used to identify themes of MI facilitators and barriers. Facilitators and barriers were then categorized using a social-ecological framework. Results: A total of 12 themes of MI facilitators and barriers were identified and categorized into two social-ecological levels: institutional factors (e.g., administrative support, resources) and intrapersonal factors (e.g., teacher confidence, ease of implementation). Conclusion: This review can inform research and practice aimed at supporting the implementation of MI in elementary classrooms.     

‘Motivate’: the effect of a Football in the Community delivered weight loss programme on over 35-year old men and women’s cardiovascular risk factors

The purpose of this study was to examine whether an innovative, inclusive and integrated 12-week exercise, behaviour change and nutrition advice-based weight management programme could significantly improve the cardiovascular risk factors of overweight and obese men and women over the age of 35. One hundred and ninety-four men and 98 women (mean age?=?52.28?±?9.74 and 51.19?±?9.04) attending a community-based intervention delivered by Notts County Football in the Community over one year, took part in the study. Height (m), weight (kg), fitness (meters covered during a 6?min walk) and waist circumference (cm) were measured at weeks 1 and 12 as part of the intervention. Changes in body weight, waist circumference and fitness for men and women were measured by a 2-way repeated measures ANOVA, with significance set to p?<?0.05.Weight, waist circumference and fitness significantly improved over time in both men (4.96?kg, 6.29?cm, 70.22?m; p?<?0.05) and women (4.26?kg, 5.90?cm, 35.29?m; p?<?0.05). The results demonstrated that the FITC lead weight loss intervention was successful in significantly improving cardiovascular risk factors in both men and women. In particular, the weight loss reductions achieved were comparable to those seen in similar, more costly men-only programmes. This is the first study to demonstrate the efficacy of such an intervention in an inclusive, mixed gender programme and more specifically, in women.
