SNS use by the Korean government: a case of Me2Day

This study examines the debates and discussions surrounding the Korean government's Me2Day, the largest social networking and microblogging site in the country used by 26 government bureaus, including the Blue House. Me2Day users post messages composed of up to 150 characters and establish links with other users through multimedia-based information and knowledge obtained from their browsers, desktop computers, e-mail messages, and mobile phones. This study provides a better understanding of the characteristics and structures of cyberspace communication between the Korean government and citizens. The results indicate that although each bureau had different goals in terms of using Me2Day, users were more likely to use the service if their bureau actively posted messages or responded to user comments. Users tended to have critical attitudes toward the Korean government when they were allowed to freely post messages and share information.     

The impact of organizational learning capacity from the socio-cognitive perspective on organizational commitment

This study is to examine the impact of organizational learning on affective commitment in Korea. In particular, this study addressed the importance of organizational learning as an HRD strategy from the socio-cognitive perspective. Data were collected from four large companies located in the area of Seoul, South Korea. There were 233 usable questionnaires yielding a response rate of 61 %. Multiple regression analysis and principal factor analyses were applied to conduct a data analysis. The results showed that a linear relationship existed between the organizational learning capacity and affective commitment (R ² = .495). Four dimensions were statistically significant with the exception of “feedback.” Participative decision-making is the most important factor. Finally, the study discussed some implications for HRD theory and practice.     

Teaching abjection: A response to the war on terror

In this paper, the author discusses pedagogy and strategy within the current climate set by the “War on Terror”. Deploying Lacanian psychoanalysis in a critique of standardized knowledge, the author develops a theory of “abject pedagogy” that seeks to subvert the current “regimes of truth” while providing educators with a viable pedagogy during this “state of emergency”.     

The current state of human performance technology: A citation network analysis of Performance Improvement Quarterly, 1988–2010

This study conducted a citation network analysis (CNA) of human performance technology (HPT) to examine its current state of the field. Previous reviews of the field have used traditional research methods, such as content analysis, survey, Delphi, and citation analysis. The distinctive features of CNA come from using a social network analysis approach to see relational and network patterns in the citation data. This CNA found that the Performance Improvement Quarterly network showed more widely but loosely connected and less centralized structural attributes than the human resource development network; the 10 most influential articles in the field were identified; frequently co‐cited articles were recognized as having a strong relationship by subsequent researchers; and five cohesive subgroups showed key topics in the field (performance, instructional design, performance support, organization/workplace, and transfer of training). Implications from the results of the CNA were elaborated on for future research in HPT.     

Reading Instruction for English Learners in the Middle Grades: a Meta-Analysis

This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper elementary and middle school students who are ELs and (b) how the magnitude of the effect varies based on student, instructional, and study characteristics. The analysis included a total of 11 studies with 46 individual effect sizes and yielded a mean effect size of g?=?0.35 across all (i.e., standardized and unstandardized) reading measures, g?=?0.01 across standardized reading measures, and g?=?0.43 across unstandardized reading measures. For all reading, unstandardized reading, all vocabulary, and unstandardized vocabulary measures, results suggest that higher quality studies tended to have smaller effects, and these effects were even more evident for unstandardized measures (i.e., one unit increase in study quality was associated with decreased effects: g?=?0.21, g?=?0.30, g?=?0.24, g?=?0.30, respectively). For all comprehension measures, effects were larger for instruction that included both vocabulary and comprehension (g?=?0.39) than for instruction that focused on vocabulary alone (g?=?0.08). Results suggest the benefit of developing and refining high-impact approaches to reading instruction for ELs that can be delivered across content areas and grades.     

Early Malnutrition and Child Neurobehavioral Development: Insights from the Study of Children of Diabetic Mothers

In this study we sought to discern whether disturbances in mothers' metabolism during pregnancy may exert long-range effects on the neurobehavioral development of the progeny. Participants were 139 Women with diabetes in pregnancy and their singleton offspring. Serial estimates of circulating maternal fuels were obtained for each pregnancy, along with detailed records of perinatal course and outcome. Offspring were administered the Wechsler Intelligence Scale for children—Revised (WISC-R) full-scale IQ scores below 70 in our cohort did not differ significantly from national estimates. Nonetheless, after statistically controlling for other influences, WISC-R verbal, performance, and full-scale IQ scores, and Bannatyne's indices of Verbal Conceptualization Ability, Acquired Knowledge, Spatial Ability, and Sequencing Ability were inversely correlated with measures, of maternal lipid and glucose metabolism in the second and third trimesters. KTEA Arithmetic scores were similarly correlated with measures of maternal lipids in the third trimester. All correlations indicate that poorer metabolic regulation was attended by poorer child performance. The effects of maternal metabolism on fetal brain and neurobehavioral development are discussed as potential intermediary factors.     

Phonological awareness and morphological awareness: differential associations to regular and irregular word recognition in early Korean Hangul readers

A large battery of reading related skills were orally administered to 111 4-year old and 118 5-year old Korean kindergartners, who were also tested on reading of regular and irregular Korean Hangul words. In regression equations, speeded naming was uniquely associated with reading of both regular and irregular words. In contrast, only the three measures of phonological awareness at the levels of phoneme onset, coda, and syllable uniquely explained Hangul regular word recognition, whereas only morphological awareness consistently explained irregular word recognition. Results suggest somewhat different cognitive demands for reading of regular and irregular words, based on the dual-route model, in Korean Hangul.     

近二十年汉语亲属词的概念结构研究综述

对于亲属词进行深入的分析,这是汉语语义学研究的需要,也是词汇学、心理学、社会学研究的需要。笔者将近二十年的汉语亲属词的研究情况予以总结。汉语亲属词概念结构的组织维度至少有四个：亲属的亲密程度、姻亲,非姻亲、辈分和对象性别。汉语亲属词的分类既受亲属词的特性影响,也受知识和经验影响,同时还受文化影响。     

Multiple perceptions of children's aggression: Differences across neighborhood,age, gender,and perceiver

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc.
