This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers’ physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from Edmonton, Canada in The Parents’ Role in Establishing healthy Physical activity and Sedentary behaviour habits study (PREPS). The PREPS questionnaire encompassed 21 variables across the constructs of the socialization model of child behaviour. Of the nine variables assessed for internal consistency reliability, eight had good (α ≥ 0.70) reliability. Of the 15 continuous variables assessed for 1-week test–retest reliability, 10 had moderate (intra-class correlation = 0.50–0.74) and 5 had good (intra-class correlation ≥ 0.75) reliability. Of the six categorical variables assessed for 1-week test–retest reliability, two had fair (К = 0.21–0.40), one had moderate (К = 0.41–0.60), one had substantial (К = 0.61–0.80), and two had almost perfect (К = 0.81–1.00) reliability. Of the 12 sedentary behaviour variables assessed for convergent validity, 7 were significantly correlated with children’s screen time, of which three were small (r ≤ 0.29), two were medium (r = 0.30–0.49), and two were large (r ≥ 0.50) effect sizes.  相似文献

Managing Discovery and Linking Services     

Leanna Jantzi  Jennifer Richard  Sandra Wong 《期刊图书馆员》2016,70(1-4):184-197

There is a growing trend toward a consolidation of services for electronic resources management, A–Z journal listings, full text link resolving, and discovery services under a single service provider. In many cases, the adoption of a discovery service from a provider that is not the same as the libraries’ existing link resolver service means managing multiple knowledgebases. In this session, three librarians gave an overview of their experiences and strategies for maintaining separate link resolving and discovery services in lieu of adopting a full suite of services from a single service provider. Each speaker presented a case study on the advantages and challenges of managing their chosen discovery service: EBSCO Discovery Service, Ex Libris’ Primo and ProQuest’s Summon, in conjunction with the CUFTS/GODOT open source knowledgebase and link resolver service.  相似文献

国际社会视角中的美国公司犯罪问题评析     

张曼  王思锋 《河南广播电视大学学报》2007,20(2):59-60

公司刑事责任是对目前越来越多以公司名义触犯刑法的法律管制,世界各国为了规范这一领域问题提出了很多有益对策。文章详细分析美国政府打击公司犯罪的微观与宏观法律措施,指出公司死亡并不是有效解决办法,关键在于制定指导公司守法行为原则后,不断补充和完善其内部法律的构建,使原则精神落实在每个具体操作环节上。其中有些法律规定也可以考虑被我国司法实践所借鉴,同时也为了向那些想多了解域外公司行为规制的人们提供必要信息。  相似文献   

Tracking Pre-service Teachers’ Changing Conceptions of Good Science Teaching: The Role of Progressive Reflection with the Same Video     

Benny Hin Wai Yung  Siu Ling Wong  Man Wai Cheng  Ching Sum Hui  Derek Hodson 《Research in Science Education》2007,37(3):239-259

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit, develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on their changing conceptions of good science teaching. PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree.  相似文献   

Being and becoming a university teacher     

Wendy McMillan 《高等教育研究与发展》2017,36(4):777-790

This study examined how one academic framed the enablements and constraints to her project of being and becoming an academic. Complexity facilitated reflection in that it provided a visual representation of data, which was used to generate a concept map, which represented as equal all the component parts of her landscape. Five spaces with emancipatory potential to assist the academic in her professional development emerged, namely: communities of practice, academic freedom, position statements, development opportunities and a supportive environment. Rather than suggesting any generalisability in the findings, the authors argue that the significance of this study is theoretical and methodological. Complexity theory has the potential to help academic development practitioners understand the landscapes in which their academics operate, and guide appropriate development opportunities.  相似文献   

绝望的反抗与时间价值的失效——《围城》与《活动变人形》比较     

张曼 《石家庄学院学报》2003,5(2):50-53

《围城》与《活动变人形》分别是钱钟书和王蒙的代表作,二者在内容上有着某些相似之处,但在结尾艺术、象征意象、叙述视角方面又有很大差异。从而显示出其主题思想存在不同。《围城》是哲学—生命层面的,《活动变人形》是社会—文化层面的,显然前者要比后者深刻得多。其原因表现在作家气质、社会环境等诸多方面。现当代作家中的同类题材中也有类似现象。  相似文献
