  • In order to develop a model for better understanding of causal relationships in resiliency factors in families of children with disabilities, 200 families participated in this adaptation of the Resiliency Model of McCubbin and McCubbin(1993). The 6 latent variables included in the hypothesized model were family stress, family hardiness, family schema, community support, family problem-solving communication, and family adaptation. The models were developed on the basis of confirmatory factor analysis and compared using covariance structure modeling (LISREL). Adequate fitness of the model was observed. Family stress showed negative effect on family schema and on family hardiness. Family schema showed positive effect on community support and on family hardiness. Family hardiness showed positive effect on family problem-solving communication, and family problem-solving communication showed positive effect on family adaptation.

  • This study investigated the effects of personal (gender, school grade and causal attribution for success and failure) and environmental (mother's evaluation of their children and mother's efficacy) variables on children's perceived competence. The subjects were 595 fourth and sixth graders and their mothers selected from 3 elementary schools in Pusan. Children's perceived competence was studied under 3 categories : scholastic, social, and athletic competence. Data were analyzed by SAS/PC+ program. Internal attribution for the success had a positive influence on perceived competence while internal attribution for failure had a negative influence on perceived competence. Mother's evaluation of their children had a stronger influence on perceived competence than mother's efficacy. Mother's evaluation of their children was the most influential variable in all 3 categories of competence while secondary and tertiary variables varied by internal attribution for success or failure and by gender.

  • In this study of the relative effectiveness of constructivist and non-constructivist approaches to shadow activity for young children, 59 children in two kindergarten classes were assigned to constructivist or non constructivist conditions. Each group participated in 12 units covering shadow search, shadow making, changing shadow size, changing shadow position, and shadow disappearance. Analysis of covariance of differences between the mean scores of the two groups on the posttests of shadow concepts and scientific attitudes revealed that the children in the constructivist group performed better than the children in the non-constructivist group. This confirms the constructivist approach to shadow activities as good science activities for young children by promoting their active experimentation using reasoning about light to foster spatio-causal relations construction.

  • The Institute of Medicine of the National Academies of Science in the United States concluded in its 2004 report that excessive indoor dampness is a public health hazard and that its prevention should be a public health goal. Water damage in buildings, such as leaks from roofs, walls, or windows, may increase indoor moisture levels. Excessive dampness may promote microbial proliferation in indoor environments, increase occupants' exposure to microbial agents, and eventually produce adverse health effects in building occupants. Epidemiological studies to demonstrate the causal association between exposure to indoor microbial agents and health effects require reliable exposure assessment tools. In this review, I discuss various sampling and analytical methods to assess human exposure to biological agents in indoor environments, their strengths and weaknesses, and recent trends in research and practice in the USA.

  • The present study was initiated under the hypotheses that value orientation of wives is closely related to their decision making style in home management and that family life satisfaction of wives varies according to their decision making style. To test the hypotheses the following procedures were undertaken; (1) developing measurement instruments for value orientation, decision making style, and family life satisfaction; (2) finding value orientation of wives, their decision making style, and their family life satisfaction by applying the measurement instruments; (3) finding the variables highly affecting value orientation, decision making style and family life satisfaction ; and (4) finding the causal mechanism among value orientation, decision making style, and family life satisfaction. In conclusion , preferences of wives for humanism in value orientation were expected to lead decision making style to person -oriented rater than task-oriented style and , furthermore, to result in higher family life satisfaction.

  • This paper empirically examines the short-run and long-run causal relationship between stock market prices and exchange rates in Chinese stock markets using monthly data from January 2002 to December 2012 retrieved from the National Bureau of Statistics of the People's Republic of China. Unit root, cointegration tests, vector error correction estimates, block exogeneity Wald tests, impulse responses, variance decomposition techniques and structural break tests are employed. This study found 1) long-run causality from exchange rates to stock prices in Chinese stock markets and 2) short-run causality from Japanese yen and Korean won exchange rates to stock prices in the Shanghai Stock Exchange strongly prevails while in the Shenzhen Stock Exchange weakly prevails. The impact of the global financial crisis from 2007 to 2009 on Chinese stock markets was insignificant.

  • In recent years, most of Supply Chain Management literature has emphasized the importance of information sharing among supply chain partners, but empirical researches are few until now, especially in Korea. The purpose of this study is to develop an empirical model focusing on information exchange among partners in supply chain, and to analyze the main factors influencing the causal relationship between information exchange and performance. Based on cross-sectional questionnaire survey on Korean manufacturing firms, this study analyzed the factors influencing information exchange such as environmental factors, organizational factors, relationship factors, and information characteristics of the sample firms. Our major findings might provide many useful insights for managers in exploring the most efficient system for information exchange among partners in the context of SCM.

  • The purposes of the study are to measure the relative importance of independent variables, to analyze relation between user satisfaction and use, and to improve the level of user satisfaction in using e-Trade system(uTradeHub). The study develops the independent variables in three dimensions(i.e the quality of system, quality of information, and quality of service), estimates the level of satisfaction on a par with these variables, and analyzes the causal relation of these variables. The major findings of the study are as follows. First, there is a significant casual relationship between the quality of system and user satisfaction, thus the hypothesis is accepted. Second, there is a significant casual relationship between the quality of information and user satisfaction, thus the hypothesis is accepted. Third, there is a significant casual relationship between the quality of service and user satisfaction, thus the hypothesis is accepted. Final, there is a significant casual relationship between the user satisfaction and use, thus the hypothesis is accepted.

  • The previous studies regarding the usability evaluation of e-government web sites focused only on deriving affecting factors and variables. They did not find the relationship of usability, user satisfaction and revisiting. The objective of this paper is to find the causal effect how the usability of e-government web sites affect to the user satisfaction and the revisiting attitude. no scope of e-government web sites included the portal site and ie liked web sites. We developed a structural equation model and performed a user test. As a result, a perceived usability affected the revisiting, but it did not intermediate the user satisfaction.
