Biological Motion Displays Elicit Social Behavior in 12-Month-Olds     

Jennifer M. D. Yoon  Susan C. Johnson 《Child development》2009,80(4):1069-1075

To test the hypothesis that biological motion perception is developmentally integrated with important social cognitive abilities, 12-month-olds ( N  =   36) were shown a display of a human point-light figure turning to observe a target. Infants spontaneously and reliably followed the figure's "gaze" despite the absence of familiar and socially informative features such as a face or eyes. This suggests that biological motion displays are sufficient to convey rich psychological information such as attentional orientation and is the first evidence to show that biological motion perception and social cognitive abilities are functionally integrated early in the course of typical development. The question of whether common neural substrates for biological motion perception and analysis of gaze direction underlies the functional integration seen behaviorally is discussed.  相似文献   

Beyond the learning process and toward the knowledge creation process: Linking learning and knowledge in the supportive learning culture     

Seung Won Yoon  Ji Hoon Song  Doo Hun Lim 《Performance Improvement Quarterly》2009,22(3):49-69

This integrative literature review synthesizes the concepts and process of organizational knowledge creation with theories of individual learning. The knowledge conversion concept (Nonaka & Takeuchi, 1995; Nonaka, Toyama, & Byosière, 2001) is used as the basis of the organizational knowledge creation process, while major learning theories relevant to working adult learners are newly synthesized into four types of individual learning processes: adaptive, generative, transformative, and reflective. The results suggest an integrative conceptual flow map of individual and organizational learning facilitated by culture and management system enablers. Implications for using this conceptual framework for practicing performance technology solutions are also discussed.  相似文献

Why Do We Indulge? Exploring Motivations for Binge Watching     

Yoon Hi Sung  Eun Yeon Kang  Wei-Na Lee 《广播与电子媒介杂志》2018,62(3):408-426

This study explored an expanded definition and motivations for binge-watching behavior. In addition to the number of episodes, the amount of time, frequency, and engagement in binge-watched programs were considered for the binge-watching definition. Study findings revealed that over half of the respondents of this study were light binge viewers. In addition, among a total of seven motivations identified in literature, only the entertainment motivation is a significant predictor of binge watching for those with a low level of binge watching, while both passing time and entertainment were found to be significant predictors for those with a high level of binge watching.  相似文献   

The development of search filters for adverse effects of surgical interventions in medline and Embase          下载免费PDF全文

Su Golder  Kath Wright  Yoon Kong Loke 《Health information and libraries journal》2018,35(2):121-129

Background

Search filter development for adverse effects has tended to focus on retrieving studies of drug interventions. However, a different approach is required for surgical interventions.

Objective

To develop and validate search filters for medline and Embase for the adverse effects of surgical interventions.

Methods

Systematic reviews of surgical interventions where the primary focus was to evaluate adverse effect(s) were sought. The included studies within these reviews were divided randomly into a development set, evaluation set and validation set. Using word frequency analysis we constructed a sensitivity maximising search strategy and this was tested in the evaluation and validation set.

Results

Three hundred and fifty eight papers were included from 19 surgical intervention reviews. Three hundred and fifty two papers were available on medline and 348 were available on Embase. Generic adverse effects search strategies in medline and Embase could achieve approximately 90% relative recall. Recall could be further improved with the addition of specific adverse effects terms to the search strategies.

Conclusion

We have derived and validated a novel search filter that has reasonable performance for identifying adverse effects of surgical interventions in medline and Embase. However, we appreciate the limitations of our methods, and recommend further research on larger sample sizes and prospective systematic reviews.  相似文献   

Technological opportunity discovery for technological convergence based on the prediction of technology knowledge flow in a citation network     

Inchae Park  Byungun Yoon 《Journal of Informetrics》2018,12(4):1199-1222

As technological convergence has recently become a mainstream innovation trend, technological opportunities need to be explored in heterogeneous technology fields. Most of the previous convergence studies have taken a retrospective view in measuring the degree of convergence and monitoring the converging trends. This paper proposes a quantitative future-oriented approach to technological opportunity discovery for convergence using patent information. In a future-oriented approach, technological opportunities for convergence are suggested by predicting potential technological knowledge flows (TKFs) between heterogeneous fields. The potential TKFs are predicted by a link prediction method in a directed network, which is suggested in this paper to represent the direction of the predicted TKFs by adapting the concept of bibliographic coupling and edge-betweenness centrality. Converging technological opportunities are proposed as incremental and radical technological opportunities by extracting the potential increased knowledge flow links and emerging knowledge flow links. Moreover, the direction and themes of the predicted potential TKFs are provided as technological opportunities for convergence. As an illustration of the proposed method, the technological opportunities between biotechnology (BT) and information technology (IT) are explored. Firms and researchers can use the proposed method to seek out new technological opportunities from various technologies so that R&D policymakers can plan new R&D projects on technological convergence.  相似文献   

Are model PISA pupils happy at school? Quality of school life of adolescents in Finland and Korea     

Junghyun Yoon  Tero Järvinen 《比较教育学》2016,52(4):427-448

This paper explores the quality of school life (QSL) of two ‘model pupils’ in Programme for International Student Assessment (PISA) tests, Finland and Korea, and investigates students’ views on the central aspects of QSL (general satisfaction, peer relations and teacher–student relations) using PISA 2012 data. It also seeks to interpret how specific institutional and sociocultural aspects are linked to QSL. The analyses show that Finnish and Korean adolescents’ views on QSL are less positive compared with the OECD average; Finnish adolescents’ views on QSL are more positive than those of Korean adolescents regarding general satisfaction and peer relations but are not clearly related to teacher–student relations. Since Finnish and Korean adolescents’ views on QSL partly differ from those of their Nordic and East Asian counterparts, the distinct Nordic or East Asian image of QSL could not be revealed in the study. This article proposes that QSL demands more attention in the era of ‘rankings and benchmarked educational models’, with consideration to the universality and uniqueness of institutional, sociocultural and historical factors of one’s own and others’ schooling.  相似文献   

Haunted Trauma Narratives of Inclusion,Race, and Disability in a School Community     

Irene H. Yoon 《Educational Studies A Journal of the American Educational Studies Association》2019,55(4):420-435

By typical definitions in the special education world, inclusion would not be recognizable as it exists at Memorial Elementary. Memorial is responding to a widely documented trend in public schools: over-representation of students of color, particularly Black and Brown students, in high-incidence special education categories, including emotional and behavioral disabilities (EBD). I conceptualize EBD as unacknowledged suppression of hauntings from transgenerational trauma—legacies of institutional racism, poverty, and attempts at dehumanization. My primary hypothesis is that Memorial’s practice and ethic of unconditional belonging has been a transformation afforded by being haunted. I argue that haunted trauma narratives affirm and reconstruct the personhood of students of color with ghosts of trauma. Through narrativizing, students of color and educators rebuild inclusion from difference-as-allowed toward Martin Luther King Jr.’s (2001) “beloved community” (p. 458). That is, Memorial has redesigned school structures, educators’ beliefs and practices, interactions with children and their families, and other aspects of everyday systems to be organized around the intersections of race, trauma, identity, and community. Though dreaming is undeniably difficult, Memorial also illustrates the transformative power of affective forces from ghosts that demand hope, justice, and healing.  相似文献   

Science-specialist Student-teachers Consider Promoting Technological Design Projects: Contributions of Multi-media Case Methods   总被引：1，自引：0，他引：1  

Bencze  Larry  Hewitt  Jim  Pedretti  Erminia  Yoon  Susan  Perris  Kirk  van Oostveen  Roland 《Research in Science Education》2003,33(2):163-187

In school science, students often experience simplistic representations of knowledge-building practices in science and technology – which, in reality, are complex, unpredictable and theory-limited. While there are a great variety of reasons (many of which are beyond teachers' direct control), this occurs partly because teachers of science generally have not had such realistic experiences. While student-teachers can develop this kind of meta-scientific literacy in university-based science teacher education programmes, this depends on the extent to which activities are legitimised through close associations with authentic school contexts. In this paper, we report effects on science-specialist student-teachers' conceptions about science and technology, and corresponding priorities for school science, after interacting with a case documentary that depicted students collaborating in development and evaluation of pneumatic-controlled robotic arms. Data, including video footage of student-teachers' interactions with cases and audio recordings of interviews with them and their teacher, indicated that many student-teachers developed more naturalistic perspectives on knowledge development in science and technology and corresponding pedagogical priorities. At the same time, most also recommended an apprenticeship for students, gradually moving them from unrealistic (e.g., following a linear model for technological design) to more realistic (e.g., accommodating flexibility in design, while pointing out such limits to creativity as techno-determinism) problem solving contexts.  相似文献   

Social scientists' data reuse behaviors: Exploring the roles of attitudinal beliefs,attitudes, norms,and data repositories     

Ayoung Yoon  Youngseek Kim 《Library & information science research》2017,39(3):224-233

Many disciplines within the social sciences have a dynamic culture of sharing and reusing data. Because social science data differ from data in the hard sciences, it is necessary to explicitly examine social science data reuse. This study explores the data reuse behaviors of social scientists in order to better understand both the factors that influence those social scientists' intentions to reuse data and the extent to which those factors influence actual data reuse. Using an integrated theoretical model developed from the theory of planned behavior (TPB) and the technology acceptance model (TAM), this study provides a broad explanation of the relationships among factors influencing social scientists' data reuse. A total of 292 survey responses were analyzed using structural equation modeling. Findings suggest that social scientists' data reuse intentions are directly influenced by the subjective norm of data reuse, attitudes toward data reuse, and perceived effort involved in data reuse. Attitude toward data reuse mediated social scientists' intentions to reuse data, leading to the indirect influence of the perceived usefulness and perceived concern of data reuse, as well as the indirect influence of the subjective norm of data reuse. Finally, the availability of a data repository indirectly influenced social scientists' intentions to reuse data by reducing the perceived effort involved.  相似文献
