The catcher in the lie: The role of emotions and epistemic judgments in changing students’ misconceptions and attitudes in a post-truth era

We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed.     

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

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.

对新规则下直拍进攻型打法发展趋势的研究

直拍进攻型打法曾经是我国乒坛的主流打法,由于缺乏创新,在近10多年一直不太景气.但是,直拍进攻型打法有其特定的优势,具有很强的抗争能力,只要创新技术、加强实力,就能登上世界乒坛的最高峰;诚然,它自身的确也存在着很多问题,加上11分赛制和无遮挡发球的实行,必定会给这种打法带来一些影响(正负双方面).因此,在新形势下对直拍进攻型打法进行进一步的深入剖析和探讨,成为我国乒坛亟待解决的课题.通过对世界优秀男子直拍进攻型打法选手的技战术进行统计与分析,并走访乒乓界权威人士和有关专家,对新规则带来的一些问题和该打法今后的发展趋势进行深入分析与探讨,为进一步提高我国直拍进攻型打法的技术水平提供科学理论和参考依据.     

反腐败的最根本途径：发扬民主,以民制权

反腐败的本质问题是民主建设问题,要根治腐败必须下大力气加强民主政治建设,健全反腐败的民主机制,即反腐败一要靠民主,以社会制约权力,增强反腐败的基础和力量;二要讲民主,以权利制约权力,保证反腐败的效率和质量.这既是历史发展的必然趋势,也是反腐败的现实需要.

热休克反应对急性运动大鼠心肌自由基代谢的影响

目的:探讨热休克反应对急性运动大鼠心肌自由基代谢的影响。方法:SD大鼠随机分为:室温安静组,室温运动组,热休克反应安静组,热休克反应运动组。热休克反应组进行热暴露处理;热暴露处理24h后,运动组大鼠进行一次急性运动,急性运动结束16h后取样。检测各组心肌组织中MDA含量和SOD的活性,检测安静组心肌组织HSP72的含量。结果:1)与室温安静组相比,热休克安静组大鼠心肌组织中的HSP72浓度显著升高(P<0.01);热休克反应安静组大鼠心肌SOD活性升高、MDA含量降低,与室温安静组相比变化不明显(P>0.05)。2)热休克反应运动组心肌MDA含量显著低于室温运动组(P<0.01),SOD活性高于室温运动组,但无统计学意义(P>0.05)。结论:热休克反应可减轻急性运动所致大鼠心肌组织SOD活性下降的程度,抑止MDA含量的升高。说明热休克反应预处理能够减轻急性运动大鼠心肌的抗氧化能力,减少自由基的生成,减轻自由基所致的损伤,对急性运动所致心肌损伤具有一定的保护作用。
