How Persuasive Are Health Advertisements in First-Person Shooter Games? Exploring Knowledge-Activation and Thought-Disruption Mechanisms     

Jorge Peña  Subuhi Khan  Christopher N. Burrows  Hart Blanton 《Communication Research Reports》2018,35(4):293-302

This study examined whether persuasive health messages embedded in shooter games have broad or targeted effects on players’ willingness to engage in risk behaviors (N = 145). Participants presented with in-game health messages discouraging alcohol-impaired driving of motor vehicles showed reduced willingness to drink alcohol and to operate both motor and nonmotor vehicles, compared to those in a no-message gaming control condition. There were no spillover effects on willingness to smoke cigarettes or marijuana, thus implying targeted persuasive effects. In addition, players experiencing high instead of low cognitive load showed decreased postexperiment willingness to drink and operate nonmotor vehicles, thus suggesting that playing a game under high cognitive load can influence players’ attitudes. The findings replicate previous research and further expand on knowledge-activation and thought-disruption mechanisms underlying the persuasiveness of health messages.  相似文献   

我国文化金融研究领域文献分析——来自2002-2016年CSSCI来源数据库的证据     

贺达  顾江 《图书馆杂志》2018,(3):26-32

随着文化产业的快速发展,文化金融成为新兴的研究领域。本文选择2002-2016年CSSCI数据库收录的文化金融相关研究文献,运用词频统计法、可视化知识图谱法、内容分析法等多种文献计量研究方法全面分析国内有关金融支持文化产业发展的研究现状。研究发现:现阶段有关金融支持文化产业发展的研究文献逐年增加,分布期刊和研究机构众多,研究范围较广,研究内容包含国际经验比较、经验分析和实证分析;但目前该领域的研究主题相对分散,研究不够深入,缺乏微观数据支撑和模型研究,缺乏构建金融支持体系操作层面的分析,缺乏对具象产业的差异化分析,这些是未来进一步研究的方向。  相似文献   

基于频度演化的领域知识关联关系涌现     

滕广青 《中国图书馆学报》2018,44(3):79-95

领域知识的生长演化问题一直是图书情报学界重点关注的主题。以网络科学思维探索知识生长过程中的关联关系涌现问题,能够对知识关联的生长模式与机制进行揭示。本研究提取知识关联关系累计44万余对,关联频度87万余次,共划分为11个时间窗口。在对时间序列领域知识网络结构属性初步判识的基础上,对关联频度分布进行时间序列分析。并从领域知识生长过程中的关联频度数量、关联频度占比、邻近窗口状态等方面,对知识关联关系及其频度进行跟踪与分析。研究结果表明,知识关联关系生长过程中,关联关系频度的分布符合幂律分布,且在领域知识发展的成熟期表现得更好。知识关联关系的生长过程具有频度层面的“富者更富”的属性,且主要遵循“择优强化”机制。尽管研究所使用的基于社会化标注系统的知识网络尚不足以囊括所有类型的知识网络,但是基于频度演化的知识关联关系涌现模式与机制,有助于促进知识网络、知识生长等领域的研究工作,对于社交网络、传播网络、交通网络等研究不无裨益。图5。表4。参考文献30。  相似文献

Increasing engagement of students with learning disabilities in mathematical problem‐solving and discussion     

Rachel Lambert  Trisha Sugita 《Support for Learning》2016,31(4):347-366

Engagement in problem‐solving and mathematical discussion is critical for learning mathematics. This research review describes a gap in the literature surrounding engagement of students with Learning Disabilities in standards‐based mathematical classrooms. Taking a sociocultural view of engagement as participation in mathematical practices, this review found that students with LD were supported towards equal engagement in standards‐based mathematics through multi‐modal curriculum, consistent routines for problem‐solving, and teachers trained in Mathematical Knowledge for Teaching. Using this small set of studies (7), we identify the need to deepen the engagement of students with LD in mathematical problem‐solving and discussion. This review concludes with implications for teaching and learning.  相似文献   

The effects of school-based physical activity interventions on students' health-related fitness knowledge: A systematic review     

《Educational Research Review》2015

This systematic review includes 34 studies examining the effects of school-based physical activity interventions on students' health-related fitness knowledge. The study design, methodological quality, and effectiveness of interventions on students' health-related fitness knowledge were analysed. The majority of the studies (79.4%) revealed significant positive intervention effects on students' health-related fitness knowledge. Studies examining adolescents were more frequently in a position to influence students' health-related fitness knowledge (87.5%) than studies examining children (75%), and studies with low methodological quality (88.8%) had more frequent positive effects than studies with moderate quality (75%). The effects on students' health-related fitness knowledge were independent of moderator variables such as the intervention content, duration and frequency. Only few studies were able to simultaneously positively influence students' health-related fitness knowledge and students' physical activity and/or fitness levels. These programmes can positively influence students' health-related fitness knowledge, but it remains unclear what the practical significance of these changes is. Further research is needed to clarify the influence of students' health-related fitness knowledge on reflection, understanding, physical activity behaviour, and overall physical literacy levels.  相似文献   

浅谈费希特知识学     

荆文凤 《鸡西大学学报》2005,5(2):24-25

费希特知识学的基础和核心是“自我”，费希特知识学就其特点来说是主观唯心主义的；费希特对自我积极实践性的颂扬反映了时代的呼声，肯定了实践的作用，尽管其强调实践是认识领域内的实践，还是为哲学发展起了推动作用。  相似文献   

数字人文研究演化路径与热点领域分析   总被引：3，自引：2，他引：1  

柯平  宫平 《中国图书馆学报》2016,42(6):13-30

数字人文是计算机学科和人文学科交叉研究的一个新领域,由计算人文和人文计算领域发展而来。本文以Web of Science核心数据集为来源,运用文献计量方法,结合可视化分析工具,对数字人文研究文献进行统计分析和内容挖掘,分析数字人文研究的前沿和热点领域,明确演化路径和发展趋势。①数字人文研究的热点领域有:数字人文的基本理论,技术驱动下的人文学术实践转向,新合作模式引发的人文学术文化变革,以及面向数字人文研究的基础设施建设;②数字人文研究的内涵更具兼容性,应强调计算转向,考虑重构人文知识的脉络与内容,构建当代知识系统及认知方式;③图书馆学的理论、方法及实践与数字人文研究形成协同发展趋势;④从技术应用和数据基础的角度看,图书馆学是数字人文产生的基础学科,也将是数字人文成果的主要应用学科之一。我国图书馆界应以融合的视角审视数字人文与图书馆发展的关系,进行数字人文的理论研究与实践探索。图10。表1。参考文献54。  相似文献
