Food (in)security communication: a Journal of Applied Communication Research forum addressing current challenges and future possibilities     

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   

Proclaiming Library Worth in a Program Prioritization Process at a Mid-Sized Public University     

Michelle J. Oh  Robin J. Harris  Lisa C. Wallis 《图书馆管理杂志》2020,60(3):250-262

Abstract

In an economic climate when colleges can no longer presume that legislators see institutions of higher learning as tacit public goods, institutions around the country are facing budget cuts. This article presents a case study of the experience of a mid-sized public state university and its Library in a budget crisis undergoing a university-wide program prioritization process. The authors review the process of writing three reports on the Library’s value, along with the approach to engaging staff in the process including a retreat. This article raises questions about what every library should consider assessing and provide tools for libraries navigating similar terrain.  相似文献   

A meta-cognitive approach to doping in sports: The effects of thought validation on attitudes related to doping

ABSTRACT

To better understand doping-related attitude change, it is important to consider not only the amount of thinking (i.e., elaboration) done by message recipients, but also the favourability of their thoughts in response to the proposal, as well as the perceived validity in their thoughts. The main goal of the present study was to analyse the effects of a meta-cognitive process (i.e., thought validation) on attitudes related to doping. Thus, we randomly assigned participants to read a message either against or in favour of legalising several doping behaviours. Participants listed their thoughts regarding the proposal and indicated the perceived validity in their thoughts, then reported their attitudes. As hypothesised, the message against legalisation elicited more unfavourable thoughts and attitudes than the message in favour of legalisation. Most relevantly, the effects of the message direction on attitudes were greater for participants with higher (vs. lower) levels of thought validity. Furthermore, consistent with the thought validation process, results revealed that thought favourability was a better predictor of attitudes for participants with higher (vs. lower) perceived thought validity, indicating that perceiving one’s thoughts as valid plays an important role in persuasion. These findings provide novel insights for research and interventions regarding doping in sports.  相似文献   

Learner Characteristics that Influence the Treatment Effectiveness of Early Literacy Interventions: A Meta‐Analytic Review     

J. Ron Nelson  Gregory J. Benner  Jorge Gonzalez 《Learning disabilities research & practice》2003,18(4):255-267

The purpose of this article was to systematically review the available research on learner characteristics that influence the treatment effectiveness of early literacy interventions. Meta‐analytic procedures were applied to a total of 30 studies that met the inclusionary and exclusionary criteria. Mean average effect sizes were computed for seven primary learner characteristic categories: (1) rapid naming, (2) alphabetic principle, (3) phonological awareness, (4) problem behavior, (5) memory, (6) IQ, and (7) demographic. The primary learner characteristics that influenced the treatment responsiveness of early literacy interventions were, in order of magnitude, rapid naming, problem behavior, phonological awareness, alphabetic principle, memory, IQ, and demographics. With the exception of the demographic category, the obtained effect sizes for the primary learner characteristics were moderately large. The demographic primary learner characteristic (i.e., disability, ethnicity, grade‐level status) of children was not statistically (p < 0.05) distinct from zero. The findings, limitations, and future research needs are discussed.  相似文献

2008年北京奥运会的举行将大大加快北京地区乃至我国的经济现代化建设的步伐。应用实证研究的方法，对历届奥运会的经济价值进行分析，指出举办奥运会对促进北京地区乃至全国的经济增长、改善劳动力就业，加快产业结构调整的积极作用。同时从资金筹措、场馆建设、产业可持续发展等方面对北京避免奥运会后可能出现的“经济低谷效应”，实现可持续发展提出了建议。  相似文献   

克莱普冰刀速滑腿部动作运动学分析     

王小虹  陶玉晶  程湘南 《冰雪运动》2003,(3):4-5

主要研究速滑腿部动作，着重分析滑行中足部和冰刀部位细微动作。主要结论为：摆动腿着冰时间(从冰刀接触冰面到刀刃完全放平)为0．1s，着冰处靠近支撑足，从录像片未观察到着冰时足艰与冰刀座有分离现象；从足艰(蹬冰腿)开始抬起到足艰与冰刀分开最大距离(此时冰刀仍然是全刃着冰)的时问为0．05-0．067s。这正是克莱普冰刀能提高运动成绩的关键所在。采用克莱普冰刀在这段时间能仍然在全刃蹬冰，延长了蹬冰时间，提高了滑行速度。此时的蹬冰主要是依靠足尖。这种情况也预示了蹬冰足蹬离冰面的最后一段时间伸展踝关节的重要性，提高伸展踝关节的速度将有助于进一步加大蹬冰的力度而提高滑行速度。  相似文献

AMPK、能量代谢与运动的关系研究     

黄涛  孙海生  夏志 《吉林体育学院学报》2006,22(4):64-65

AMP激活的蛋白激酶（AMPK）不仅可以作为细胞水平的能量感受器，还可以通过细胞因子参与调节机体整体的能量消耗和能量摄人。运动等应激可以激活AMPK。参与调节骨骼肌葡萄糖代谢和脂肪酸氧化等能量代谢过程。运动训练可影响骨骼肌AMPK基因表达，进而参与到运动训练的机体适应机制。  相似文献
