MEMORY,SELF‐EFFICACY,AND ADAPTABILITY IN KOREAN AMERICAN OLDER ADULTS: A COLLECTIVE STUDY OF FOUR CASES     

Kyung A. Kim  Daniel J. Mueller 《Educational gerontology》2013,39(5):407-423

Currently influential educational theories emphasize a causal and linear relationship among memory self‐efficacy, psychological well‐being, and memory performance. That model, however, does not consider an important mediating variable: the adaptability of the aging self. This collective study of four cases (four Korean American older adults) was conducted to provide a more comprehensive understanding of the interrelationships among these variables, with the expectation that useful insights might be gained through the in‐depth study of specific cases. Each case showed a unique pattern of the interplay of these cognitive and affective variables. The findings suggest that perceptions of memory functioning and psychological well‐being are mitigated by the adaptability of the aging self, rather than being directly related to the experiences of age‐related losses or to actual memory perfor‐  相似文献   

A deterministic resampling method using overlapping document clusters for pseudo-relevance feedback     

Kyung Soon Lee  W. Bruce Croft 《Information processing & management》2013

Typical pseudo-relevance feedback methods assume the top-retrieved documents are relevant and use these pseudo-relevant documents to expand terms. The initial retrieval set can, however, contain a great deal of noise. In this paper, we present a cluster-based resampling method to select novel pseudo-relevant documents based on Lavrenko’s relevance model approach. The main idea is to use overlapping clusters to find dominant documents for the initial retrieval set, and to repeatedly use these documents to emphasize the core topics of a query.  相似文献   

Exploring the effect of heuristic factors on the popularity of user-curated ‘Best places to visit’ recommendations in an online travel community     

Lin Li  Kyung Young Lee  Sung-Byung Yang 《Information processing & management》2019,56(4):1391-1408

In online travel communities, ‘Top-K best places to visit’ recommendations are gaining more attention from travelers due to their ubiquitous access to the Internet, but little empirical effort has been made to investigate what factors lead to the popularity of user-curated ‘best places to visit (BP2V)’ recommendations. This research therefore aims to identify and validate the heuristic factors affecting the popularity of BP2V recommendations. Based on the heuristic-systematic model (HSM) of persuasion, we derive recommender-related (i.e., recommender's identity disclosure, reputation, experience, and location of residency) and recommendation-related (i.e., number of places recommended, helpfulness rating, number of comments added, and length of recommendation) heuristic characteristics of BP2V recommendations and investigate their impact on recommendation popularity. In addition, this study examines the moderating effect of destination category (i.e., attractions, food, shopping, and activities) on the relationship between heuristic characteristics and the popularity of BP2V recommendations. Our empirical results, which were based on 565 ‘best places to visit in the U.S.’ recommendation postings from Qyer.com, a major online travel community in China, suggest that recommender's identity disclosure, reputation, number of places recommended, helpfulness rating, and length of recommendation are positively associated with recommendation popularity. We also found that the relationships between heuristic factors and the popularity of BP2V recommendations are contingent on destination category. This study will contribute to the body of knowledge on online travel communities and HSM and provide valuable implications for general travelers and managers in the tourism and hospitality industry.  相似文献   

An evaluation study on the educational value of teaching practicum in secondary schools     

Sun-Geun Baek  Eun Hye Ham 《Asia Pacific Education Review》2009,10(2):271-280

The purpose of this study is to evaluate the educational value of teaching practicum in secondary schools. For this purpose, on the basis of literature review and interviews, three evaluation criteria for measuring educational value of teaching practicum are constructed as follows: (1) practical teaching competence, (2) readiness for teacher, and (3) maturity in character. A total of 29 pre-service teachers in the College of Education at Seoul National University in South Korea participated voluntarily in this study, and their practical teaching competence, readiness for teacher, and maturity in character were measured twice before and after teaching practicum. As a result, the teaching practicum had significantly improved pre-service teachers’ practical teaching competence, readiness for teacher, and maturity in character. In other words, teaching practicum increases the educational value. This study provides a conceptual framework and three instruments for measuring the educational value of many other teaching practicums. An earlier version of this paper was presented at the 8th International Conference on Education Research, Seoul National University, Seoul, Korea, October 23–25, 2007.  相似文献   

Knowledge complementarity and knowledge exchange in supply channel relationships     

Kyung Kyu Kim  Narayan S. Umanath  Joo Young Kim  Fred Ahrens  Beomsoo Kim 《International Journal of Information Management》2012

Existing literature on knowledge exchange in inter-organizational relationships (e.g., a supply channel) reveals two opposing forces at work: (1) collaborative behavior and (2) opportunistic behavior. A concurrent assessment of the opposing perspectives and the contingencies under which each is relevant for supply channel performance can add valuable insights about the dynamics of knowledge exchange. We juxtapose the two behavior patterns using social capital theory and transaction cost economics (TCE) respectively as the explicators and employ knowledge complementarity as the contingency to reconcile the opposing behavior patterns. The choice of knowledge complementarity in this role stems from ample theoretical and empirical support in prior literature about the criticality of this factor in inter-firm knowledge exchange.  相似文献   

A Cross-Cultural Test of Implicit Theories of Re-requesting     

Min-Sun Kim  Atsushi Oshio  Eun Joo Kim  Katsuya Tasaki  Kenton Bruce Anderson  Ayano Yamaguchi 《Communication Research Reports》2019,36(1):14-23

Extant U.S. research shows that when a persuader’s initial message is rebuffed, the next requesting message will tend to be ruder and more aggressive than the initial appeal. The robustness of these results has rarely been tested cross-culturally. Using conversational constraints theory, we further explicate implicit theories by investigating the perceived importance of constraints of re-requesting styles across two cultural-linguistic groups (i.e., Korean and American English speakers). Consistent with the “rebuff phenomenon,” results revealed that people rated the task constraint (“clarity”) as significantly more important, and the three face-related constraints (“concern for the other’s feelings,” “minimizing imposition,” and “avoiding negative evaluation”) as significantly less important for the second-attempt requesting than for the initial requesting. Some of these tendencies were more pronounced among American English speakers than among Korean speakers.  相似文献   

Reading motivation in two languages: an examination of EFL college students in Korea     

Kyung Ja Kim 《Reading and writing》2011,24(8):861-881

This study was designed to identify underlying factors that motivate language learners to read in a foreign language (L2) context. It also examined the relationships between L1 and L2 reading motivation and any differences in reading motivation based on the learners?? academic majors and L2 reading proficiency. 259 Korean EFL college students participated in this study. Participants?? L1 and L2 reading motivation was measured using a Likert scale questionnaire and their L2 proficiency was estimated by test scores in their reading classes. This study yielded a four-factor solution for L2 reading motivation: learning goal-oriented motivation, intrinsic motivation, avoidance of reading, and utility value of L2 reading. The results indicated that learning goal-oriented motivation and utility value of L2 reading were the two primary indicators for the participants?? desire to read in English. The study also demonstrated that the factor-based L2 reading motivation scales correlated with some of the L1 reading motivation scales in the relatively low range but statements about the connection or transfer issue of reading motivation between the two languages must be tentative. All L2 reading motivation scales revealed significant differences between English and non-English majors except in utility value of L2 reading. Furthermore intrinsic and avoidance scales also differed significantly depending on the participants?? L2 reading proficiency.  相似文献

An online authoring tool for creating activity-based learning objects     

Jeong Yong Ahn  Gil Seong Mun  Kyung Soo Han  Sook Hee Choi 《Education and Information Technologies》2017,22(6):3005-3015

As higher education increasingly relies on e-learning, the need for tools that will allow teachers themselves to develop effective e-learning objects as simply and quickly as possible has also been increasingly recognized. This article discusses the design and development of a novel tool, Enook (Evolutionary note book), for creating activity-based learning objects (LOs). This tool has three general foci: 1) creation of various activity-based objects for experimental learning or learning by doing while simultaneously offering as many learning resources as a real e-book that services as both a textbook and a notebook, dual functions that paperback books can never provide; 2) management of all aspects of live instructor-led classroom training in a network environment, such the Web and or a mobile network; 3) facilitated use of data on students’ progress to monitor their understanding of the material and to provide other meaningful information through learning analytics.  相似文献
