Understanding the majority opinion formation process in online environments: An exploratory approach to Facebook     

Sangwon Lee  Taehyun Ha  Daeho Lee  Jang Hyun Kim 《Information processing & management》2018,54(6):1115-1128

Majority opinions are often observed in the process of social interaction in online communities, but few studies have addressed this issue with empirical data. To identify an appropriate theoretical lens for explaining majority opinions in online environments, this study investigates the skewness statistic, which indicates how many “Likes” are skewed to major comments on a Facebook post; 3489 posts are gathered from the New York Times Facebook page for 100 days. Results show that time is not an influential factor for skewness increase, but the number of comments has a logarithmic relation to skewness increase. Regression models and Chow tests show that this relationship differs depending on topic contents, but majority opinions are significant in overall. These results suggest that the bandwagon effect due to social affordance can be a suitable mechanism for explaining majority opinion formation in an online environment and that majority opinions in online communities can be misperceived due to overestimation.  相似文献   

Lessons learned and tables turned: ‘(in)security’ and media representations in the 2018 World Cup     

Jan Andre Lee Ludvigsen 《Soccer & Society》2019,20(7-8):986-999

ABSTRACT

This essay follows up on an article published in Soccer & Society prior to the 2018 World Cup in Russia. There it was argued that this edition of the World Cup served as particularly interesting for the academic field focussed on sport-mega events (SMEs) and ‘security’, because of its uniquely securitized climate. Written immediately after the 2018 World Cup, the present essay reflects upon the event’s ‘security’ and mega-event security more broadly. It revisits some ‘security-related’ episodes. Then, special attention will be given the media discourse vis-à-vis ‘hooliganism’. The essay argues that the media discourse took an unorthodox ‘turn’ with regard to English ‘hooligans’, who, compared to past events, were portrayed as being ‘in risk’ – rather than being the group generating ‘the risk’ of football-related violence and public disorder.  相似文献   

Platform War vs. Platform Synergy? A Longitudinal Analysis of Media Substitution between Personal Computers and Mobile Devices     

Su Jung Kim  Vijay Viswanathan  Hye Mi Lee 《广播与电子媒介杂志》2020,64(2):65-88

ABSTRACT

Research on media substitution theory has examined substitutional and/or complementary relationships between new and existing media. This study focuses on the growth of mobile platforms and investigates the relationship between mobile devices and personal computers. Using Nielsen’s panel data that provide electronically recorded media usage (N = 2,396), this study analyzes yearly changes in time allocation to mobile devices and PCs at total and content-specific usage levels during mobile 4G transition. Results suggest a complementarity dynamic between mobile devices and PCs; however, the patterns were more nuanced in light of the role of individual and structural factors when determining media choice.  相似文献   

“Lies,damn lies and statistics”: a history of museum visits in Australasia     

Lee Davidson  Conal McCarthy 《Cultural Trends》2019,28(1):36-55

ABSTRACT

While a great deal of attention has been paid to museum visit data in the last few decades, very little is known about long-term trends. This article examines the distinctive history of museum visits in Australasia through a comparative study of eight key institutions from across the region. Archival research was undertaken at each institution to compile as complete as possible a data set of annual visitation from opening until present day. Any stated changes in funding, admission charges, buildings etc. were also recorded, along with comments indicating contemporary explanations for fluctuations in visitation. Sources included official documents such as annual reports and trustee minutes, as well as visitor books and attendance records. We provide an initial overview of the quantitative and contextual data we collected from the case study museums focusing on a number of key questions: How have museums in Australasia been counting and reporting visit data over the past 150 years? What does this reveal about changes over time in the perceived value of visit data and museum attitudes towards their visitors? What are the key trends in museum attendance at the local, national and regional level in Australia and New Zealand? What contemporary explanations were given for fluctuations in museum attendance and are they supported by a long-term, cross-institutional comparison of the data? The study provides insights into historical shifts in thinking about the importance of visitors, appropriate methods for recording visitation, and the value of this data. The findings are also relevant to how museums today interpret attendance figures. The ways in which visit data were included or excluded from historical narratives about the value of museums highlights the constructed nature of visitor data and raises questions about the role of visitor research in contemporary museums.  相似文献

Online Teaching Resources     

Annis Lee Adams 《Public Services Quarterly》2020,16(3):172-178

Abstract

Because of the global COVID-19 pandemic during the spring of 2020, colleges and universities found themselves rapidly moving all courses to online modalities, a format that many instructors were not experienced in or comfortable with. Academic librarians were called upon to help support faculty in this sudden transition, as well as migrating their own library services and instruction online. For many, it felt like a mad scramble to find best practices for online teaching, or even just “good-enough” practices, as well as specific tools that instructional faculty and librarians could utilize to keep their students engaged and learning during such a trying time. At the time of this writing, some universities have announced that they will continue to hold most, if not all, courses online in the fall 2020 term. Resources to support online teaching are critical now, and they will continue to be important going forward even after the global pandemic subsides. The reviews in this column cover a variety of online instructional tools and instructional support sites. The resources reviewed range from providing best practices for online pedagogy, creating engaging formative assessment tools, developing video discussion boards, creating interactive images, using virtual bulletin boards for student collaboration, and ensuring online content meets accessibility requirements. These resources will be useful for librarians and instructional faculty as they continue to teach in the online environment.  相似文献   

Validation of the swimming competence questionnaire for children     

Derwin K. C. Chan  Alfred Sing Yeung Lee  Duncan J. Macfarlane  Martin S. Hagger  Kyra Hamilton 《Journal of sports sciences》2020,38(14):1666-1673

ABSTRACT

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequency), which supported SCQ’s concurrent and criterion validity. Average variance extracted for the SCQ factors exceeded cut-off criteria supporting discriminant validity. In Study 2, pre-test SCQ scores correlated significantly and positively with the SCQ scores, self-efficacy, intention, and swimming frequency at post-test, which supported SCQ’s test-retest reliability and predictive validity. Positive intraclass correlation between SCQ scores and coach ratings at post-test provided evidence for SCQ’s inter-rater reliability. SCQ scores significantly improved at post-test, which supported SCQ’s ecological validity. In conclusion, findings indicate that the SCQ is a valid and reliable measure to assess primary school children’s swimming competence, in terms of swimming distance and basic water survival skills.  相似文献

The Shaping of a Gendered School     

Lee Shu-Ching 《Chinese Education & Society》2014,47(4):46-52

Gender education has been emphasized in Taiwan in recent years. Related research undertaken such as textbook reviewing and teachers' gender consciousness has pointed out potential problems in regard to gender in education. The process of shaping gender in a school per se has not yet been explored. This article aims to elaborate on how school authorities produce/reproduce stratification of school organization through the differentiation of male-strong/female-weak traits and through the segregation of educational work. An examination of school discourses and institutional arrangements demonstrates the underlying gendered nature of a school culture and the reproduction of differentiation, segregation, and stratification.  相似文献   

Evaluating and comparing Singaporean and Taiwanese eighth graders’ conceptions of science assessment     

Tzung-Jin Lin  Aik-Ling Tan  Min-Hsien Lee 《Research in Science & Technological Education》2017,35(4):391-408

Background: Researchers have indicated that assessment practices and methods should support learners’ construction of meaningful understanding of knowledge. Understanding students’ conceptions of assessment will enable us to construct more realistic, valid and fair assessments. Learners’ conceptualization of assessment would be imperative to serve as an essential reference to evaluate their learning progress.

Purpose: This study evaluated and compared the Singaporean and Taiwanese middle school students’ conceptions of science assessment. Within-country gender comparisons were also explored.

Sample: 424 Taiwanese and 333 Singaporean eighth graders were invited for a cross-country comparison.

Design and methods: The participants completed a questionnaire named Conceptions of Science Assessment.

Results: The findings showed that the summative assessment dominates in the Taiwanese classrooms, while formative and summative assessment are usually perceived in Singaporean classrooms. The Singaporean students had a greater tendency than their Taiwanese counterparts to perceive the purpose of assessment as a way of reproducing knowledge, and the formative assessment as improving learning, problem-solving, and critical judgment. No gender differences were found among either the Singaporean or the Taiwanese students.

Conclusions: Educators in both countries should provide learners with more opportunities to experience process-oriented science assessment activities and de-emphasize the usage of examination-oriented practices to achieve the sophistication of conceptions.  相似文献
