  • This study was conducted to identify factors that influenced teachers' adoption of digital textbooks and causal relationships among the factors identified. Chasm theory was used in developing strategies for adoption of digital textbooks that consider teachers' innovativeness. This study also employed the information technology adoption model of Davis (1989) that illustrates decision making processes for the adoption of instructional media such as digital textbooks. Based on these two theories, a measurement instrument measuring teachers' innovativeness, perceived usefulness, perceived ease of use, and intention of use was developed and validated through a series of reliability and validity tests. Causal relationships among the factors were examined using structural equation modeling. The result indicated that: a) perceived ease of use had a directional effect on perceived usefulness and an indirect effect on intention of use; and b) perceived usefulness had a direct effect on intention of use. Implications of this finding are discussed especially for the efforts in developing strategies for teachers' adoption of digital textbook. For example, when digital textbooks are introduced into public schools, teachers' perception of the usefulness of digital textbooks, beyond just ease of use, should be considered.

  • The purpose of this study is to investigate the trend of the familism and the awareness of parent-supporting, showing how personal background variables affect the familism and how the familism affect the awareness of parent-supporting, The data were collected from May 20, 1998 till June 5, 1998 for 621 college students consisted of 300 male strdents and 321 female students. SOSS-PC was used for data analysis, and the data were tested by ANOVA, t-Test, Pearson's Correlation, Multiple Regression Analysis, and Duncan Test. The major findings are as follows: 1) The college students' familism generally tends to show low scores (M=2.79), indicating the modern familism-individualism. 2) The college students' awareness of parent-supporting is reported to be high(M=4.23); the highest awareness of parent-supporting is financial supporting, the next is service supporting, then emotinal supporting. 3) For personal background variables, male students rather than female students, the students who have parents with more monthly income, and those who have experience in living with grandparents tend to have more traditional familism. 4) Older students, the students with more traditional familism, those who find more satisfaction in family relations, and male students rather than female students tend to show higher awareness of parent-supporting. 5) In causal relations among the personal background variables, the familism, the awareness of parent-supporting, the variables with a significant impact on the familism are gender, parents' monthly income, and experience in living with grandparents, in order of impact. Age, the familism, satisfaction in family relations, and gender, in order of impact, affect the awareness of parent-supporting. Especially, the familism has the highest correlations with the awareness of financial, emotional, and service supporting, and shows considerable causal impact on the awareness of parent-supporting in general. That is to say, the more the familism, the more the awareness of the parent-supporting.

  • The purpose of this study was to explore a causal model of mother's parenting and children's locus of control to self-control in elementary school children. The subjects were 582 children of 4th, 5th and 6th grade. The instruments were Self-Control Rating Scale for Children, Locus of Control Scale for Children and Parenting Scale. The major findings of this study were as follows. 1) Children's locus of control, mother's warmth-acceptance and permissiveness-nonintervention , mother's education level and children's sex predicted children's self-control. 23% of the variance of children's self-control was explainer by these variables. 2) Mother's warmth-acceptance had a direct and an indirect positive effect through children's locus of control on children's self-control and was the first contribution factor. Children's locus of control had a first direct effect on children's self-control. 3) Mother's permissiveness-nonintervention had a direct and an indirect negative effect through children's locus of control on children's self-control. Mother's education level had a direct and an indirect effect through children's locus of control on children's self-control. Children's sex had a direct and an indirect effect through mother's rejection-restriction on children's self-control. Mother's rejection-restriction had an indirect effect through children's locus of control on children's self-control. Family income had an indirect effect through mother's parenting on children's self-control. Father's education level had an indirect effect through mother's permissiveness-nonintervention on children's self-control.

  • The present research aimed at researching the relationships among place attachment, residential evaluations and satisfaction in a medium-sized post-communist Romanian city. Studies on post-communist cities are scarce and this research tried to fill that gap. This research is part of a government project that intended to significantly reform three medium-sized cities in the Western part of Romania and transform the urban space. Since the three of them are relatively small-sized and close spatially, the project intends to undertake massive reforms of the communications and services of the three cities. In this article, we report findings on the city of Hunedoara. A representative random sample was selected, and a total of 384 people were interviewed, with an overall reliability of the sample of 95%. The instruments used to gather the data were the Neighbourhood Perceived Environmental Quality Scale and a composite measure of place attachment was also included. The structure of each scale was checked using exploratory factor analysis. We tested alternative causal models using structural equations modelling. Our model showed a good fit to the data and explains satisfaction in the city adequately. Results show that satisfaction is directly predicted by the general evaluation of the city and by residential privacy. Residential noise and place attachment influence satisfaction indirectly. The results are discussed and some policy recommendations are formulated.

  • The purpose of this study was to investigate the effects of students' prior knowledge on scientific reasoning process performing a task of controlling variables with computer simulation and to identify a number of problems that students encounter in scientific discovery. Subjects for this study included 60 Korean students: 27 fifth-grade students from an elementary school; 33 seventh-grade students from a middle school. The sinking objects task involving multivariable causal inference was used. The task was presented as computer simulation. The fifth and seventh-grade students participated individually. A subject was interviewed individually while the investigating a scientific reasoning task. Interviews were videotaped for subsequent analysis. The results of this study indicated that students' prior knowledge had a strong effect on students' experimental intent; the majority of participants focused largely on demonstrating their prior knowledge or their current hypothesis. In addition, studnets' theories that were part of one's prior knowledge had significant impact on formulating hypotheses, testing hypothesis, evaluating evidence, and revising hypothesis. This study suggested that students' performance was characterized by tendencies to generate uninformative experiments, to make conclusion based on inconclusive or insufficient evidence, to ignore, reject, or reinterpret data inconsistent with their prior knowledge, to focus on causal factors and ignore noncausal factors, to have difficulty disconfirming prior knowledge, to have confirmation bias and inference bias (anchoring bias).

  • This study aimed to demonstrate 'moderated mediation' effect of self-control on the relationship of neuroticism-smart phone addiction-school adaptation. For this purpose, we carried out a survey targeting middle school students who were vulnerable to smart phone addiction, and 1,400 middle school students responded to questionnaire. The results showed that the moderated mediation effect of self-control was statistically significant. In detail, school satisfaction and school performance, the sub-factors of school adaptation, showed significant results but social relation non-significant. Concerning moderating effect of self-control, results supported significantly moderating effect, demonstrating that high level of self-control showed consistently lower level of smart phone addiction than low level of self-control regardless of level of neuroticism. We can find the meanings of this study in having demonstrated, on the one hand, the causal process of smart phone addiction, and on the other, moderating effect and moderated mediation effect on this causal process through interaction between neuroticism and self-control. Finally, limitations and suggestions for future research were discussed.

  • The purpose of this paper is to identify the causal role both emotionally based satisfaction and service reputation by examining the relationships among each dimensions of service quality, cognitive satisfaction, emotionally based satisfaction, service reputation and service loyalty in mobile telecommunication company. The results of the study are as follows: First, conviction quality had not influence on both cognitive satisfaction and emotionally based satisfaction, but tangibles quality had more influence on cognitive satisfaction than emotionally based satisfaction and responsiveness quality had more influence on emotionally based satisfaction than cognitive satisfaction. It found that there was a significant positive relationship between dimensions of the service quality, cognitive satisfaction and emotionally based satisfaction, and dimensions of the service quality affect satisfaction either directly or indirectly through emotion. Second, consumer satisfaction had more effect on service loyalty through service reputation than direct effect. Therefore, service loyalty can be build by increasing emotionally based satisfaction and service reputation to customer who is perceived as good service.

  • This study attempted to test the scale effect of MAUP, particularly focusing on the spatial autocorrelation of sex crime, correlations among neighborhood structural variables, and causal mechanism leading to sex crime. Analysis results of nation-wide Eup-Myon-Dong and Si-Gun-Gu data discovered that the spatial autocorrelation, correlations among independent variables, and determinant coefficient of multiple regression of Si-Gun-Gu level were generally bigger and stronger than those of Eup-Myon-Dong, which appeared to be due to the averaging effect. Regarding the causal effect to sex crime, two interesting results were found: First, the ratio of non-apartment residency lowered sex crime at both levels contrary to the hypothesis. Second, the ratio of food and lodging increased sex crime only at Eup-Myon-Dong level. These suggested that future research need to perform more detailed analyses dividing data into subsets such as urban vs. rural and/or economically advantaged vs. disadvantaged areas.
