Megan K. Schraedley  Hamilton Bean  Sarah E. Dempsey  Mohan J. Dutta  Kathleen P. Hunt  Sonia R. Ivancic 《Journal of Applied Communication Research》2020,48(2):166-185

ABSTRACT

This forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities.  相似文献   

职业足球改革困境：一种非均衡国家治理模式的反思     

周嘉豪 《河北体育学院学报》2020,34(2):1-5

运用文献资料法和逻辑分析法,从非均衡国家治理角度对我国职业足球改革面临的困境进行研究。通过梳理相关文献提出,当前国家治理模式具有非均衡性,存在各主体参与失范、治理权责分配失衡的问题,市场、社会、个人主体话语权较弱、参与性不足,形成了较强的政府依赖路径。对职业足球改革各主体之间的关系进行阐述,认为政府和足协是改革话语权的掌握者和资源的分配者,其他主体参与改革作用较小。指出,尚未明确职业足球的发展动机、足协组织能力与管理效能不足、各主体缺乏有效联系与合作是非均衡国家治理模式的具体表现;政府的非市场手段治理、市场失灵与第三部门失灵、个体意识与自我治理不足是其深层次原因。在此基础上提出相应的发展对策。  相似文献   

基于深度学习的MOOC论坛探索型对话识别方法研究     

董庆兴  李华阳  曹高辉  夏立新 《图书情报工作》2019,63(5):92-99

[目的/意义]大规模在线开放课程论坛具有丰富的用户评论数据。从大量未区分的评论数据中，自动识别出知识密度较高的探索型对话并挖掘其潜在价值，对于改善教师教学质量以及提高学生知识水平具有重要影响。[方法/过程]首先利用GloVe方法训练词向量，加强对文本语义的理解，然后利用卷积神经网络自动学习文本特征，提出一种基于深度学习的探索型对话自动识别模型，并在学堂在线平台《心理学概论》课程论坛标注数据集上进行实证与对比研究。[结果/结论]实验结果显示，利用GloVe方法预训练词向量以及在训练过程中不断对词向量进行学习修正能够提高模型效果。该模型识别探索型对话的F1值为0.94，相较于传统的朴素贝叶斯方法（0.88）、逻辑斯谛回归方法（0.89）、决策树方法（0.88）以及随机森林方法（0.88）取得较大提升，具有较高的实用性和较低的学习成本。  相似文献   

Blended learning in higher education: professional development in a Hong Kong university     

Jennifer Catharine Evans  Hennie Yip  Kannass Chan  Christine Armatas  Ada Tse 《高等教育研究与发展》2020,39(4):643-656

ABSTRACT

Online learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning.  相似文献

关于我国引入足球职业裁判制度的思考          下载免费PDF全文

何博芳 《河北体育学院学报》2019,33(4):24-28

职业裁判制度是足球职业化发展到一定阶段的必然产物，其引入将有力提升我国裁判执法水平，助推我国足球事业发展。认为，职业裁判是职业联赛健康发展的关键力量，是足球运动技术发展的客观要求，是提升足球裁判整体水平、统一集中管理的需要。目前，我国的足球裁判存在基数小、水平低、待遇低、环境差等问题。只引入足球职业裁判制度而无配套措施，可能无法解决根本矛盾；目前的国内联赛规模也还无法满足职业裁判发展需求，职业转换难度大及退休保障不足，也阻碍着我国职业足球裁判制度的实施。指出，应加快足球联赛发展，与职业裁判发展互促互进；健全体育裁判法律法规，改革职业裁判组织管理方式；建立健全职业裁判员的薪酬和退休保障体系；注重青少年裁判培养，全面提升在职裁判员业务水平。多管齐下，使足球职业裁判制度发挥更好的效果。  相似文献

Exploring the work and learning stories of para‐teachers in a college for further education in England     

Benita McLachlan 《Support for Learning》2014,29(3):230-243

This paper reports findings from a research project which developed and introduced the Enhanced Learning Support Assistant Programme (ELSAP). This was a source of professional development for learning support assistants who were supporting students with additional learning needs in a college for further education in England. The purpose of this paper is to share findings from the project and to report on how learning support assistants experienced their work in inclusive college classrooms. The research project was a mixed methods study with participants drawn from learning support assistants within one college for further education in England. Data was collected throughout the 14‐week intervention. Findings indicate that issues exist around the uniqueness of the vocational curriculum and the implications this has for classroom support. It also shows how conflicting classroom procedures can generate feelings of confusion and how learning support workers often feel lonely in their role with no natural opportunity to mix with others. Furthermore, it indicates how a general lack of knowledge about teaching and learning contribute to them experiencing difficulty when performing their role which feed their views that a college for further education can be a complex and hostile environment to work in.  相似文献   

Unconscious and unnoticed professional practice within an outstanding school for children and young people with complex learning difficulties and disabilities     

Richard Crombie  Lesley Sullivan  Kate Walker  Rebecca Warnock 《Support for Learning》2014,29(1):7-23

This article describes a three‐year project undertaken at Pear Tree School for children and young people with severe and multiple and profound learning difficulties. Lesley Sullivan, the school's head teacher, believed that much of the value within the work of this outstanding school went unidentified by existing approaches to planning, monitoring and evaluation. Richard Crombie, educational psychologist, was engaged to work on the project. Also involved were Kate Walker and Rebecca Warnock, deputy head teachers, as well as the whole staff, children and some parents. The project takes as its starting point that essential, but very often unnoticed and unconscious, professional practice is rooted in implicit processes learnt experientially. We set ourselves the task of finding meaningful frameworks for identifying and developing that practice. This meant close observation within and outside school coupled with feeding back to staff, and their subsequent engagement with and use of explanatory frameworks.  相似文献
