Structural change in search engine news service: a social network perspective

This research investigates structural change made by Naver's online news section and how it has impacted the overall traffic flow of Korea's online news. This paper examined 45 websites in 2008 and 2010, and the total number of pages viewed within these sites was considered in the analysis. Social network analysis was applied to study the relationships between the news sites. The analysis through degree centrality and Bonacich powers shows that there has been a shift in market leadership. In 2007, Naver, the top search engine in Korea, stepped down from its leading position after they started to provide news services. Daum, the second largest search engine, has taken over the central position as the most influential news site. Based on the results of this study, practical implications for online service markets and theoretical implications for online services are recommended accordingly.     

Wartime collaboration in question: an examination of the postwar trials of the Chinese collaborators

This paper examines the political aspects of the postwar trials of the Chinese collaborators and their arguments, at the trials, against the charges of treason. Against the dominant scholarship on their collaboration with Japan, it argues that the Chinese collaborators had a different version of nationalism, which emphasized the different roles and functions of the state during the anti‐Japanese war, and that wartime collaboration was, in part, a product of their reflections on the Guomindang’s history and its political culture since 1927. The fates of the major collaborators, as the trial cases of Zhou Fohai and Chen Gongbo show, were determined, this paper argues, not by legal crimes they committed but rather mainly by their former political affiliations in the intraparty politics, which revealed the political character of the trials. The political aspects seemed to serve to disclose further the innate problems and inability of the party and its Nationalist Government, which were the main reasons for its ‘failure’ in 1949.     

Proximity effects on the dynamics and outcomes of scientific collaborations

This paper uses path overlap, an innovative measure of functional proximity, to examine how physical space shaped the formation and success of scientific collaborations among the occupants of two academic research buildings. We use research administration data on human subject protection, animal use management, and grant funding applications to construct new measures of collaboration formation and success. The “functional zones” investigators occupy in their buildings are defined by the shortest walking paths among assigned laboratory and office spaces, and the nearest elevators, stairs, and restrooms. When two investigators traverse paths with greater overlap, both their propensity to form new collaborations and to win grant funding for their joint work increase. This effect is robust across two very differently configured buildings. Implications for scientific collaboration and the design and allocation of research space are considered.     

Influences of an inquiry-based ubiquitous gaming design on students’ learning achievements,motivation, behavioral patterns,and tendency towards critical thinking and problem solving

In this paper, an inquiry-based ubiquitous gaming approach was proposed. The objective of the study was to enhance students’ performances in in-field learning activities. To show the advantages of the approach, an experiment was carried out to assess the effects of it on students’ learning achievement, motivation, critical thinking, and problem solving. Furthermore, the students’ behavioral patterns were investigated via content and sequential analysis methods. The experimental outcomes show that the approach promoted students’ performances of learning achievement and intrinsic motivation; moreover, the students’ perceptions of their problem solving and critical thinking were significantly promoted as well. The learning behavior analysis further show that the designated approach stimulated the participants to actively engage in field observation, comparison, and data searching in the context ware in-field learning activity.     

Research Trends in Technology-Enhanced Chemistry Learning: A Review of Comparative Research from 2010 to 2019

Chemistry is a subject which involves a number of abstract concepts, making it a difficult and frustrating learning process for many students. Educators and researchers believe that technology could provide an opportunity to address this problem. However, it is challenging to find a model for appropriately and successfully integrating technology into chemistry education. Therefore, in this study, a review was conducted on the technology-enhanced chemistry learning studies published in Social Science Citation Index (SSCI) journals from 2010 to 2019. This study searched the target articles from the Web of Science (WOS) database and excluded those studies that did not adopt a comparative research design. Finally, 60 studies were included in this research trend analysis. A coding scheme was developed for the types of technology, the types of learning tools, the roles of technology in chemistry learning, learning topics, learning environments, participants, research designs, and the learning outcomes the researchers evaluated. From the analysis results, it was found that (1) inorganic chemistry and physical chemistry courses were the main learning topics, while the formal classroom was most often referred to as the research setting. The most frequently discussed issue was students’ learning achievement. (2) Regarding technology integration, offering students learning content through personal computers was the main activity mode. The technology was used for lower-level implementation, that is, providing supplementary materials for students. (3) Finally, using keyword analysis, it is possible to extract the recent concerns of the researchers, and from the results of the study, it is clear that the researchers are placing increasing emphasis on learners’ experience and skill development in the learning process. Accordingly, this study highlights the features of the research trends and then provides suggestions for researchers in the technology-enhanced chemistry learning field.

     

Inhibition: Its Stability and Correlates in Sixteen- to Forty-Month-Old Children

Inhibition was assessed in 144 Swedish children when they averaged 16 months of age using a composite measure tapping sociability toward strange adults, noninvolvement in peer play, and parental ratings of fearfulness. 91 children entered out-of-home care within 2 weeks of these initial assessments. Children were observed in this setting playing with peers; teachers and parents also rated children's adjustment to the out-of-home care settings. 1 and 2 years later, the children were assessed again, both at home and in the alternative care settings. Results showed that individual differences in inhibition were stable over the 2 years of the study. Inhibited children engaged in less high-quality peer play both at home and in the alternative care settings, and they were less able to play alone in their mothers' absence. On contemporaneous but not subsequent ratings, inhibited children had more difficulty adjusting to out-of-home care. Inhibition was not itself affected by out-of-home care experiences, and there were no sex differences in inhibition.
