Enhancing Research Impact in Heritage Conservation     

Theocharis Katrakazis  Cath Dillon  Petra Juvan  Stavroula Golfomitsou 《文物保护研究》2018,63(8):450-465

This paper examines how research impact is defined, measured, and generated – with a view to understanding how it can be enhanced within heritage conservation. It examines what is meant by ‘impact’ and how it can be promoted within heritage science through effective inter-disciplinary collaboration. Following a general examination of the current discourse concerning research impact, the study examined: (i) active research networks within heritage science; (ii) research planning and evaluation practices within heritage science; and (iii) the experiences of users (i.e. conservators and other heritage professionals) within research collaborations. Terminologies surrounding the notion of impact and the various phases of the research process were reviewed – from the initial identification of a knowledge gap to the eventual application of new findings in practice. Next, the reach and diversity of research collaborations (as identified through publication co-authorship) were studied to characterise the inter-disciplinary nature of heritage science and its connectedness to users. Findings showed substantial growth in international research collaborations over recent years, predominantly involving academic- and research-oriented institutions – although the engagement of heritage institutions has proportionally decreased. In addition, a worldwide survey of institutional planning and evaluation practices revealed a general reliance on processes driven by the interests of researchers – the systematic consideration of stakeholder opinion and evaluation of research outcomes being less common. Finally, a series of semi-structured interviews with senior heritage professionals explored their experience of collaborative research. The results identified key areas where strategic support is needed to promote user participation and enhance impact. These include training for research readiness, engagement, and impact for both researchers and users; better methods for needs and outcome assessment; affordable open access options and greater diversity of knowledge exchange opportunities. Finally, the need for ethical guidelines for responsible research, and greater emphasis on non-academic impact within research rating systems are discussed.  相似文献   

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   

Pathways of Immigrant Political Socialization: Examining the Role of News Media,Social Connections,and Community Interaction     

Wenlin Liu  John Gastil 《Journal of Intercultural Communication Research》2014,43(3):238-263

Going beyond the traditional socioeconomic status model of political participation, this study examines pathways that lead to the sociopolitical incorporation of immigrants in the USA, with a focus on the role of communication socialization agents. Using a Current Population Survey sample of 7,626 first-generation immigrants in the USA, results show that communication socialization agents significantly contribute to immigrants’ political socialization, and an important mediating path translates political learning into greater political engagement. Results also identify ethnic differences in how socialization variables affect immigrants’ socialization.  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
