This paper reports on efforts aimed toward the development of more effective procedures for identifying mothers who are at elevated risk for problems in parenting. We present data from two independent samples of known maladaptors and corresponding comparison mothers and report on our attempts to cross-validate a promising screening instrument composed of items that index social support and parenting attitudes. The resultant 20-item scale correctly identified over 90% of maladaptive and comparison mothers. When this scale was cross-validated on a second independent sample of maladaptors and comparison mothers, it was again almost 90% accurate. Issues concerning the field application of this promising instrument are discussed and its possible limitations are considered. 相似文献

Research Findings: To test children’s use of testimony of others, 3 – 9 years (N = 227) made judgments about a potential peer transgression in which the intentions of the protagonist were ambiguous, after hearing two different forms of testimony. The 2 forms of testimony were (a) opposing opinion-based testimony from an adult authority versus a peer consensus group and (b) knowledge-based testimony (eyewitness testimony) that was counter to the participants’ initial judgments. Findings revealed that when testimony was presented in an opinion-based format, children were likely to side with the opinion that reflected their own interpretation of the peer encounter, regardless of whether the opinion came from a peer consensus or an adult authority. However, when knowledge-based testimony was introduced in support of the opposite of children’s initial interpretation of the ambiguous peer encounter, children most often changed their initial judgment to align with the new testimony. That is, children used knowledge-based testimony but not opinion-based testimony to evaluate a potential transgression. Practice or Policy: These findings demonstrate that the way in which testimony is delivered to children has a direct influence on their decision making about peer interactions and has relevance for teacher–student discourse in the classroom. 相似文献

The purpose of this article is to provide insights into the effects of Internet Protocol Television (IPTV) service quality and reveal mediation effects in the process of forming the repurchase intention. This study incorporates additional theoretical construct, perceived enjoyment, to reflect IPTV characteristics using extended technology acceptance model (TAM). This study empirically investigated a research model and conducted a survey of IPTV service users. The results of this study are as follows. First, IPTV service quality is summarized as design, security, and customer service, which is supported by second-order factor analysis. Service quality had an influence on perceived usefulness, perceived ease of use, and perceived enjoyment. Second, perceived ease of use had a significant effect on perceived enjoyment, and perceived usefulness also had an effect on repurchase intention. Third, attitude, trust, and satisfaction had a positive effect on repurchase intention. To reveal the impact on repurchase intention of the IPTV service quality, this study proposes customer acceptance on IPTV service based on a modified TAM. 相似文献

The purpose of this study is to develop the evaluation factors for the Subject Guide for Korean Modern Literature, which is provided by the National Library of Korea, to enhance the guides as an effective public service. In the study, the following final evaluation factors were identified: four evaluation domains (use, content, format, and collaboration), 23 evaluation components, and 67 evaluation items and questions. The results of the study showed that key evaluation components included the reliability of the website, user communication, accessibility to the subject guides, book search capability, provision of information in a consistent format, and the scope of the subject guides. When the subject-specific bibliography system of the National Library of Korea was examined by applying the developed evaluation factors, it was found that the system satisfied only 37 (55.2%) of 67 evaluation items: 8 (40%) of 20 items on use, 13 (66%) of 20 items on content, 15 (88%) of 17 items on format, and 1 (10%) of 10 items on collaboration. Accordingly, the entire subject-specific bibliography system that is currently in use needs to be reviewed, and changes and improvements need to be made utilizing the derived evaluation factors. In particular, it is imperative to develop a strategy to facilitate collaboration among users and librarians in charge, and a more effective subject guide system. 相似文献

The current study examined how planned happenstance skills (i.e., curiosity, flexibility, persistence, optimism, and risk-taking) changed during school-to-work transition and how career-related variables were associated with the initial levels and change rates of planned happenstance skills. In a sample of 307 South Korean college students, all planned happenstance skills except for risk-taking decreased over time. Furthermore, some of the career-related variables were associated with the initial level and the change rates of planned happenstance skills. In sum, the current study suggests that utilizing planned happenstance skills may be a worthwhile pursuit during school-to-work transition. 相似文献

Marginal likelihood-based methods are commonly used in factor analysis for ordinal data. To obtain the maximum marginal likelihood estimator, the full information maximum likelihood (FIML) estimator uses the (adaptive) Gauss–Hermite quadrature or stochastic approximation. However, the computational burden increases rapidly as the number of factors increases, which renders FIML impractical for large factor models. Another limitation of the marginal likelihood-based approach is that it does not allow inference on the factors. In this study, we propose a hierarchical likelihood approach using the Laplace approximation that remains computationally efficient in large models. We also proposed confidence intervals for factors, which maintains the level of confidence as the sample size increases. The simulation study shows that the proposed approach generally works well. 相似文献

PurposeThis study analyzed the process of changes in Korean Library and Information Science curriculum and evaluated the courses currently available by using a perception survey of librarians in the field. It also explored a possible demand for new courses, while suggesting compulsory, core, and optional courses for Bachelor's degree curriculum in Library and Information Science worldwide including Korea and the US.Design/Methodology/ApproachThis study progressed through a total of 5 steps as follows: investigating the background of why current courses of Library and Information Science were offered (interview), finding out the current courses in Library and Information Science (homepage search and phone interview), finding out which courses students have actually completed among those available (literature and resource research), evaluating the practicality of the available courses by librarians in the field (survey), and exploring the demand for new courses (survey). In addition, this study analyzed the process of change in the courses offered by investigating the curriculum over the last 20 years.FindingsFirst and foremost, it was found that the decision of which course will be offered is strongly influenced by faculty. Second, in the analysis of the process of opening up new courses, it was revealed that the number of courses is growing and the courses are becoming more diversified and more specific. Third, the survey results of the completion of curriculum for the last three years in 10 universities demonstrate that only 50% of the available courses are being completed. Fourth, in the survey of which courses the librarians in the field think are necessary among the 90 courses suggested, 21 courses scored more than 4 points in a 5-point Likert scale regarding the demand for new courses. Fifth, the new courses which scored high levels of demand points were: Practice in Organizing and Managing Web Resources, Library Planning, Marketing, and Assessment, Understanding Information Technology for Managing Digital Collections, and Information and Communication in a Digital Age. Sixth, this study shows that there is a high level of agreement between courses completed by students and those which gained high levels of demand points in the practicality evaluation.Limitations/ImplicationsAs this study was performed in Korea where the Bachelor's degree course is fundamental, it will contribute valuable information to countries where universities have recently opened or are trying to open programs for Bachelor's degrees in Library and Information Science such as the US, or to curriculum study in countries such as China and Japan which have educational environments similar to Korea. However, similar studies need to be performed in different countries.Originality/ValueThis study has great significance as it has analyzed not only the curriculum of the last 20 years but also discovered how many of the newly created courses have actually been completed by students and the opinions of librarians in the field on these courses; there has not been such an encompassing study as this either inside or outside of Korea. 相似文献

Electronic word-of-mouth (eWOM) has been identified as a key factor affecting online sales. However, the factors leading to eWOM in the open-market context are not fully understood. Since many Internet vendors have adopted the open-market business model, it is essential to understand the factors for eWOM leading to the success of open-market business. This study investigates factors affecting eWOM in the open-market context based on a sequential combination of qualitative and quantitative research methods. The exploratory findings in the qualitative study form the basis for the quantitative study survey research. The findings from this mixed methods study indicate the significance of three new factors (information-sharing desire, self-presentation desire, and open-market reward) and two established factors (open-market satisfaction and open-market loyalty) affecting eWOM directly and indirectly. This study makes a useful contribution to the broader literature on eWOM. These findings also inform open-market providers as to how to promote and manage eWOM for online business success. 相似文献
