As Digital Media develops into a mature market, the proper referencing of digital content is increasingly critical. The Identification of Parties who contributes to content is key to ensure efficient discovery services and royalty tracking. Far from being simple numbers, Party Identifiers such as International Standard Name Identifiers (ISNI) are built on rigorous structures meeting the requirements of diverse media such as books, music or films. Designed to accurately identify Natural Persons and Legal Entities alike, Party Identifiers must also support language variances, cultural diversity and stringent data privacy regulations. 相似文献

Social media allows for the creation of bottom-up online communities that encourage the government to utilize a two-way participatory media model, rather than a traditional broadcast media model. The purpose of this study is to examine the current status of social media usage in both Korean and U.S. governments, present several issues and suggest future directions. 相似文献

In this study, a two‐tier diagnostic test for understanding malaria was developed and administered to 314 Bruneian students in Year 12 and in a nursing diploma course. The validity, reliability, difficulty level, discriminant indices, and reading ability of the test were examined and found to be acceptable in terms of measuring students' understanding and identifying alternative conceptions with respect to malaria. Results showed that students' understanding of malaria was high for content, low for reasons, and limited and superficial for both content and reasons. The instrument revealed several common alternative conceptual understandings students' hold about malaria. The MalariaTT2 instrument developed could be used in classroom lessons for challenging alternative conceptions and enhancing conceptions of malaria. 相似文献

Previous studies have provided mixed results for the effects of social constraints on career maturity. However, there has been growing interest in these effects from the time perspective. Few studies have examined the effects of social constraints on the time perspective which in turn influences career maturity. This study examines the mediating effect of the present-oriented perspective on the relation between social constraints and career maturity. The results based on a panel survey of middle and high school students in Korea indicate that the time perspective mediates the relation between socioeconomic status (SES) and career maturity regardless of the level of academic achievement. The results have important implications for intervention programs for low-SES children’s time perspective, which may mitigate the transmission of social constraints, thereby raising the bar for their academic and career goals: Such programs may be useful for enhancing low-SES children’s career readiness. 相似文献

This study analyzes US and South Korean news coverage of the H1N1 pandemic to examine cross-cultural variations in attention cycle patterns, cited sources, and news frames. A content analysis was conducted on 630 articles from US and Korean newspapers during the period of April to October 2009. It found that attention cycle patterns, news frames, and sources varied across the two countries according to professional norms, cultural values, social ideologies, and occurrences of relevant events. While US news coverage showed two phases of waxing and waning attention, Korean news coverage showed five phases. The frames used in US news stories placed more emphasis on attribution of responsibility, action, and reassurance. Other framing variations were found as news attention in each country rose and fell. Regarding sources used, Korean news stories relied more on governmental sources, while US news stories used a greater diversity of sources. This study advances research on variations in the attention cycle for transnational issues by specifying how journalists’ framing of social problems can differ according to the following: cultural factors, the shape of the news attention cycle, and the occurrence of events related to the issue at hand. 相似文献

This study assessed the association between preservice teacher-related variables [i.e., age, adapted physical education (APE) and special education (SPED) coursework, experience teaching students with disabilities and perceive competence] on measures of the Physical Educators' Intention toward Teaching Individuals with Disabilities II – Preservice Survey (PEITID-II-PS). The PEITID-II-PS used the Theory of Planned Behavior (TpB) ( Ajzen, 2002) on preserive physical education teachers (n = 213) purposely selected from universities in China, Korea, and the United States. Results indicated that both intention and perceived behavioral control were predicted by teaching experience and perceived teaching competency. Attitude toward the behavior variable was predicted by prior teaching experience, special education coursework, and age. Age and perceived teaching competency were associated with behavioral beliefs. 相似文献

In the last few decades, changing socioeconomic and family structures have increasingly left children alone without adult supervision. Carefully prepared and limited periods of unsupervised time are not harmful for children. However, long unsupervised periods have harmful effects, particularly for those children at high risk for inattention and problem behaviors. In this study, we examined the influence of unsupervised time on behavior problems by studying a sample of elementary school children at high risk for inattention and problem behaviors. The study analyzed data from the Children's Mental Health Promotion Project, which was conducted in collaboration with education, government, and mental health professionals. The child behavior checklist (CBCL) was administered to assess problem behaviors among first- and fourth-grade children. Multivariate logistic regression analysis was used to evaluate the influence of unsupervised time on children's behavior. A total of 3,270 elementary school children (1,340 first-graders and 1,930 fourth-graders) were available for this study; 1,876 of the 3,270 children (57.4%) reportedly spent a significant amount of time unsupervised during the day. Unsupervised time that exceeded more than 2 h per day increased the risk of delinquency, aggressive behaviors, and somatic complaints, as well as externalizing and internalizing problems. Carefully planned afterschool programming and care should be provided to children at high risk for inattention and problem behaviors. Also, a more comprehensive approach is needed to identify the possible mechanisms by which unsupervised time aggravates behavior problems in children predisposed for these behaviors. 相似文献

Research on second-generation diasporic reception practices is rare, and it is the goal of this article to continue the nascent inquiry on multiple-generation diasporic audiences. The complicated ways in which diasporic identity is negotiated allows for greater understanding of the border zones that multiple-generation diasporas inhabit. Fully acculturated but not fully included, second-generation diasporas infuse their identities with meanings drawn in part through reception of transnational popular media and the development of fan communities. For Korean Americans, it is a way of identifying with a transnational home identity that allows for counterhegemonic identification. Boundaries of fan communities, however, exclude as well as include. Intraethnic taste hierarchies define what counts as authentically ethnic and who counts as sufficiently Korean. 相似文献

Photo-crosslinkable gelatin methacrylate (GelMa) microspheres are applicable to deliver cells or drugs in biological or biomedical applications. To fabricate GelMa microdroplets, a flow focusing technique with advantages of size control and rapid production was used in a T-junction microfluidic device. Instability played an important role in promoting microdroplet uniformity. 5 wt. % GelMa prepolymer solution mixed with cells affected cell-induced instability. At low flow rate ratio of GelMa to mineral oil below 0.200, stability was maintained regardless of GelMa concentration (5 and 8 wt. %) and cell presence, which led to uniform microdroplet generation. In contrast, instability at high flow rate ratio above 0.200 was worsened by cell presence and unstable jetting length, resulting in the generation of non-uniform cell-laden microdroplets. Therefore, the effect of cell-induced instability on microdroplet generation was minimized at a low flow rate ratio. 相似文献

In operational equating situations, frequency estimation equipercentile equating is considered only when the old and new groups have similar abilities. The frequency estimation assumptions are investigated in this study under various situations from both the levels of theoretical interest and practical use. It shows that frequency estimation equating can be used under circumstances when it is not normally used. To link theoretical results with practice, statistical methods are proposed for checking frequency estimation assumptions based on available data: observed‐score distributions and item difficulty distributions of the forms. In addition to the conventional use of frequency estimation equating when the group abilities are similar, three situations are identified when the group abilities are dissimilar: (a) when the two forms and the observed conditional score distributions are similar the two forms and the observed conditional score distributions are similar (in this situation, the frequency estimation equating assumptions are likely to hold, and frequency estimation equating is appropriate); (b) when forms are similar but the observed conditional score distributions are not (in this situation, frequency estimation equating is not appropriate); and (c) when forms are not similar but the observed conditional score distributions are (frequency estimation equating is not appropriate). Statistical analysis procedures for comparing distributions are provided. Data from a large‐scale test are used to illustrate the use of frequency estimation equating when the group difference in ability is large. 相似文献
