An analysis of the development and use of theory in library and information science research articles     

Sung-Jin Kim  Dong Y. Jeong 《Library & information science research》2007,28(4):548-562

This study identifies the state and characteristics of theoretical research in library and information science journals by examining the number and the quality of theory incidents. Theory incident is characterized as an event in which the author contributes to the development or the use of theory in his/her own paper. This study assumes that both theory building and theory use are intertwined to construct a cohesive body of knowledge in the filed. Theory incidents were identified by a content analysis of 1661 articles in four LIS journals from 1984 to 2003. The findings suggest that 41.4% of the articles contributed to the development or use of theory. The overall proportion of theoretical articles has increased. They showed a tendency to converge into a few subfields, such as information seeking and use or information retrieval. However, the declining share of theory development articles in recent journal issues and the overall low level of theory incidents are urging LIS researchers to the importance of continuous and creative research in LIS.  相似文献   

Where do alliances come from?: The effects of upper echelons on alliance formation     

Jerry W. Kim  Monica C. Higgins 《Research Policy》2007,36(4):499-514

Alliances with established organizations provide young firms with resources necessary for survival. We build on recent organizational research examining the effect of upper echelons on attracting powerful intermediaries to understand how young biotechnology firms establish alliances with established organizations. Drawing upon the concept of homophily, we test hypotheses regarding the extent to which young firms and partners match along specific homophily dimensions. Our findings from an event-history analysis of 3,200 career histories of managers who took biotechnology firms public between 1979 and 1996 show that alliance formation is related to status homophily and role-based homophily between young and established organizations.  相似文献   

Patent document categorization based on semantic structural information     

Jae-Ho Kim  Key-Sun Choi 《Information processing & management》2007

The number of patent documents is currently rising rapidly worldwide, creating the need for an automatic categorization system to replace time-consuming and labor-intensive manual categorization. Because accurate patent classification is crucial to search for relevant existing patents in a certain field, patent categorization is a very important and useful field. As patent documents are structural documents with their own characteristics distinguished from general documents, these unique traits should be considered in the patent categorization process. In this paper, we categorize Japanese patent documents automatically, focusing on their characteristics: patents are structured by claims, purposes, effects, embodiments of the invention, and so on. We propose a patent document categorization method that uses the k-NN (k-Nearest Neighbour) approach. In order to retrieve similar documents from a training document set, some specific components to denote the so-called semantic elements, such as claim, purpose, and application field, are compared instead of the whole texts. Because those specific components are identified by various user-defined tags, first all of the components are clustered into several semantic elements. Such semantically clustered structural components are the basic features of patent categorization. We can achieve a 74% improvement of categorization performance over a baseline system that does not use the structural information of the patent.  相似文献   

Governance Initiatives Creating a Demand-Driven E-Commerce Approach: The Case of Denmark     

Kim Viborg Andersen  Niels Bj  rn-Andersen  Jason Dedrick 《The Information Society》2003,19(1):95-105

The Danish e-commerce strategy is a highly ambitious effort to become the world's leading IT nation. Instead of a production-led approach aimed at stimulating domestic hardware and software production, Denmark has pursued a demand-oriented approach focused on promoting the widespread adoption of e-commerce in the Danish society. The Danish government has developed a number of e-commerce initiatives via public-private sector partnerships--an approach we refer to as "governance." So far, it appears that Denmark has been successful in promoting business-to-business (B2B) e-commerce, with a number of Danish companies being global leaders in the use of B2B applications. On the other hand, Denmark has had less success in achieving widespread use of business-to-consumer (B2C) e-commerce. This article analyzes the Danish national environment for e-commerce, discusses four sets of governance initiatives aimed at the development of e-commerce, and analyzes the reasons for its success in B2B and relative failure in B2C adoption.  相似文献   

Student plagiarism in higher education in Vietnam: an empirical study     

Khang Do Ba  Khai Do Ba  Quoc Dung Lam  Dao Thanh Binh An Le  Phuong Lien Nguyen  Phuong Quynh Nguyen 《高等教育研究与发展》2017,36(5):934-946

This paper assesses and compares the prevalence of plagiarism across different student and assignment characteristics at a university in Vietnam, using the similarity index reported by the text-matching software Turnitin as a proxy measure of plagiarism on a sample of 681 student papers. The findings present a level of match higher than reported in earlier studies at universities outside of Vietnam, with an average similarity index of 29.06%. Controlling for the gender and major of the students, the extent of plagiarism is implied to be negatively correlated with the students’ academic performances and with the likelihood of being caught, and positively correlated with the length of the assignments. Thus, this study, relying on actual text-matching data rather than self-reported surveys, provides the first empirical test of two theoretical plagiarism models proposed in the literature. The explanatory factors confirmed by this study illustrate the potential benefits of the use of software tools to detect plagiarism and can help refine academic integrity policy formulations for universities.  相似文献   

The Spockian Mother: Images of the “Good” Mother in Dr. Spock’s The Common Sense Book of Baby and Child Care, 1946–1992     

Catherine A. Dobris  Kim White-Mills  Rachel D. Davidson  Toula V. Wellbrook 《Communication quarterly》2017,65(1):39-59

Dr. Spock’s, The Common Sense Book of Baby and Child Care, one of the best-selling self-help texts of all-time, “second only to the Bible in popularity” (Meakin & Tattersall, 2004) was one of the most influential childcare books in American culture. The author has been both heralded and disparaged as instrumental in the shaping of untold generations. In the present study, we address the rhetorical construction of the Spockian Mother as she is developed during Spock’s tenure from 1946–1992. We employ a feminist rhetorical perspective to examine the progression of Spock’s texts in order to understand how patriarchal images of motherhood are constructed and maintained through Spock’s lifetime and the first 46 years of its publication. We argue that Spock both reinforced and challenged the institution of motherhood; he challenged institutionalized motherhood by encouraging mothers to “trust themselves” while simultaneously conforming to a patriarchal model of motherhood which is at odds with empowered mothering.  相似文献   

Culture matters in educational policy transfer: the case of curricular reforms in the two Koreas during the Soviet and US military occupation     

Sun Kim 《教育政策杂志》2017,32(3):372-385

This paper investigates the influence of cultural and historical factors on educational policy transfer, drawing on an analysis of the curricular reforms made during the Soviet and US military occupation of the two Koreas. In South Korea, curricular changes were made, such as the introduction of the subject of social studies, in order to teach democratic procedures and concepts. In North Korea, a socialist–communist ideology was extensively promoted, along with an attraction to the Soviet Union as a model state to follow. In both contexts, the localization of the reforms was influenced by the authoritarian legacy of Confucianism and Japanese colonization, and the nationalism that had been fostered for the purpose of state formation. The Korean case indicates that while investigating the influence of culture on educational policy transfer, it is important to identify the unique characteristics of educational traditions and nationalism of a country, and to analyze how the newly transferred policies and ideas are received by local actors in their searches for meaning and power.  相似文献   

Evaluating the outcomes of a school based Theraplay® project for looked after children     

Yvonne J. Francis  Kim Bennion  Sarah Humrich 《Educational Psychology in Practice》2017,33(3):308-322

Research shows that Looked After Children (LAC) may experience emotional instability which can reduce their capacity to engage with education. This study evaluates an attachment based therapeutic Theraplay® intervention designed to bridge the gap between the emotional well-being of LAC and their engagement in education. Twenty LAC between the ages of five to 11 from nine schools participated in the project over eight months. The mixed method study used a repeated measures design. Strengths and difficulties questionnaires were used pre- and post-intervention; semi-structured interviews with teaching staff were conducted and children’s views were gathered. Quantitative results show a reduction in the children’s total strengths and difficulties stress scores post-intervention. Qualitative feedback shows noticeable changes in the children’s relationship skills, confidence and engagement with education. The complexities of supporting LAC in education and implications for educational psychology practice are explored.  相似文献   

The impact of resilience on L2 learners’ motivated behaviour and proficiency in L2 learning     

Tae-Young Kim  Yoon-Kyoung Kim 《Educational studies》2017,43(1):1-15

This exploratory study focused on the factors that constitute second language (L2) learners’ resilience, and how these factors are related to L2 learning by investigating what relation resilience may have to motivated behaviour and proficiency in English learning. A total of 1620 secondary school learners of English participated in a questionnaire survey. By analysing the quantitative data, five resilience factors were extracted: perceived happiness, empathy, sociability, persistence, and self-regulation. Confirmative factor analysis using AMOS proved that these five factors are distinctive constructs. Among the factors, persistence was identified to play the most influential role in L2 learning. Persistence showed the highest correlations with, and the strongest explanatory power for, motivated behaviour and English proficiency. It is suggested that resilience can be further explored as an individual differences factor in L2 learning, which is involved in L2 learning process and outcomes.  相似文献   

A Hierarchical Rater Model for Constructed Responses,with a Signal Detection Rater Model     

Lawrence T. DeCarlo  YoungKoung Kim  Matthew S. Johnson 《Journal of Educational Measurement》2011,48(3):333-356

The hierarchical rater model (HRM) re‐cognizes the hierarchical structure of data that arises when raters score constructed response items. In this approach, raters’ scores are not viewed as being direct indicators of examinee proficiency but rather as indicators of essay quality; the (latent categorical) quality of an examinee's essay in turn serves as an indicator of the examinee's proficiency, thus yielding a hierarchical structure. Here it is shown that a latent class model motivated by signal detection theory (SDT) is a natural candidate for the first level of the HRM, the rater model. The latent class SDT model provides measures of rater precision and various rater effects, above and beyond simply severity or leniency. The HRM‐SDT model is applied to data from a large‐scale assessment and is shown to provide a useful summary of various aspects of the raters’ performance.  相似文献
