经连续五天称重法进行的膳食营养调查发现，我省皮划艇运动员（男性）以膳食中实际获得的营养素跟供给量标准比较，总热量与各营养素的摄入量除维生素Ａ不足（仅占标准的７８．１％）外，其余均超标；三大热能营养素的比例不尽合理（蛋白质２０６．９克，脂肪１７１．５克，碳水化物７０２克分别占总热量的１６％、２９．８％和５４．２％），脂肪量偏高，碳水化合物相对不足。建议在食谱中增加主食、减少脂肪，同时补充维生素Ａ，从而保证皮划艇运动员能得到合理的营养。  相似文献   

Quality,Innovation, and Financial Sustainability     

Summer Harlow 《Journalism Practice》2018,12(5):543-564

Entrepreneurial, independent digital media sites arose in response to disruption in the journalism industry brought on by emerging technologies. This study explores this trend in Latin America from the perspective of audiences. Based on surveys of readers of entrepreneurial digital news sites in Guatemala and Nicaragua, this mixed-methods study offers a snapshot of who these readers are and what they are interested in. Results showed readers of the Guatemalan and Nicaraguan news sites valued equally quality journalism and innovation, but differed when it came to the importance they placed on the sites’ business models. This study also illuminated a new dimension of innovation, one from the readers’ perspective. While some respondents associated innovation with use of new technologies, in general readers defined innovation as unique (to the region) and alternative (to mainstream media) ways of doing journalism; their definition, unlike that of journalists, was not necessarily technologically driven.  相似文献   

Health literacy and consumer health information     

Maria J. Grant PhD 《Health information and libraries journal》2023,40(1):1-2

The rigours of the past few years have demonstrated the importance of good health literacy levels with the imperative of being able to obtain and interpret information to maintain and improve one's health never more apparent. With this in mind, this issue is focused on consumer health information, the gender and population group differences that exist in information seeking behaviour, the challenges of understanding medical explanations and terminology, and existing criteria to assess and ultimately produce better consumer health information.  相似文献   

Parent Surveys for Teacher Evaluation     

Kenneth D. Peterson  Christine Wahlquist  Julie Esparza Brown  Swapna Mukhopadhyay 《Journal of Personnel Evaluation in Education》2003,17(4):317-330

Parent or guardian perceptions play a specialized role in the evaluation of school teachers. Parents are important stakeholders in teacher success, they are in some instances partners in the teachers' work, parents have unique personal information about student learning, and they can report on the teacher duties to inform parents about the classroom and child progress. This study analyzed the responses of parents to 12 survey items concerning teacher performance in 201 classrooms. The surveys were used as part of an innovative teacher evaluation program in which teachers elected to include parent feedback as one objective data source for annual review. In this study three factors emerged as important concerns for parents: humane treatment of students, support for pupil learning, and effective communication and collaboration with parents. Recommendations for use of specific survey items can be based on the empirical results of this sampling. The data gathered by parent surveys define one dimension of quality which may vary in importance from one teacher to another.  相似文献   

Library Jargon Creates Barriers for Potential Users of Health Library and Information Services     

Helen Kiely 《Health information and libraries journal》2020,37(3):228-232

This paper is based on Helen Kiely’s Masters dissertation on MA in Library and Information Service Management, successfully completed at the University of Sheffield in 2018. The aim of the study was to explore the extent to which users of a health care library service understood common terminology used by clinical librarians/information professionals. A survey was developed based on the terminology used for common services and was distributed to staff and students at an acute NHS Foundation Trust. One hundred and eight people participated over a four week period and were asked to provide definitions to the terms. Analysis of the responses for accuracy and common themes indicates that jargon can be a barrier to user access and recommendations are made with respect to the need for outreach to users and the language used in this practice for creating better accessibility.

The effect of beetroot juice supplementation on repeat-sprint performance in hypoxia     

Georgina L. Kent  Brian Dawson  Lars R. McNaughton  Gregory R. Cox  Louise M. Burke  Peter Peeling 《Journal of sports sciences》2019,37(3):339-346

This investigation assessed the effect of dietary nitrate (NO₃^?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO_2peak 53.1 ± 8.7 mL.kg^?1.min^?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYP_BR; 13 mmol NO₃^?) or NO₃^–depleted BR placebo (HYP_PLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO₂) was measured during the warm-up. There were no significant differences observed between HYP_BR and HYP_PLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYP_BR compared with HYP_PLA. There was a moderate effect for VO₂ to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO₃^? may not improve repeat-sprint performance in hypoxia but may reduce VO₂ during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.  相似文献

The Status of Literature: English teaching and the condition of literature teaching in schools     

Andrew Goodwyn 《English in Education》2012,46(3):212-227

Although the curriculum subject of English is continually reviewed and revised in all English speaking countries, the status of literature is rarely questioned: i.e. that it is of high cultural value and all students should be taught about it. The concerns of any review, in any country, are typically about what counts as literature, especially in terms of national heritage, and then how much of the curriculum it should occupy. This paper reports on three inter‐related pieces of research that examine the views of in‐service and pre‐service English teachers about their experiences of teaching literature and their perceptions of its ‘status’ and significance, both at official level and in the classroom; it draws attention to how England compares with some other English‐speaking countries and to the need to learn from the negative outcomes of political policy in England. The findings suggest that the nature of engagement with literature for teachers and their students has been distorted by official rhetorics and assessment regimes and that English teachers are deeply concerned to reverse this pattern.  相似文献   

Reconsidering the role of the primary special educational needs co-ordinator: policy, practice and future priorities     

Christine Szwed 《British Journal of Special Education》2007,34(2):96-104

This article considers the impact of recent policy designed to define the roles and responsibilities of special educational needs co-ordinators (SENCos). The international drive towards the inclusion of children with special educational needs within the mainstream has led many schools to reconsider their structures and practices. In the UK, the SENCo role lies at the heart of these structures and the Government has sought to define this role both within a revised Code of Practice for special educational needs and in a set of national standards. In this article, Christine Szwed, Director of Studies for Initial Teacher Education at the University of Birmingham, reports the findings of a survey examining the context of SENCo role management within a group of primary schools. The findings indicate that the role cannot be generalisd and that SENCos are operating in increasingly complex contexts within very different management structures. Christine Szwed argues that, to be effective, SENCos must be enabled to work at a whole-school level and that the co-ordination of special needs is a development issue for the whole staff.  相似文献

Southern Illinois University Edwardsville (SIUE) has seen a dramatic increase in international student enrollment in the last four years. To serve this rising population effectively, librarians at SIUE created a research study to explore the information needs and academic experiences of international students at SIUE. The study employed a mixed-methods approach including a survey as well as in-depth interviews and photo diaries. The results provide insight into international students’ library use and academic life.  相似文献
