This study investigates the direct and indirect effects, mediated by audit committee quality, of managerial ownership, institutional ownership, and profitability on intellectual capital (IC) disclosure. The object observed of this study is companies listed on the Indonesia Stock Exchange (IDX) in the 2014-2018 period that are classified as high intellectual capital-intensive industries. Based on the sampling method, purposive sampling, 51 companies were selected as samples. This study used path analysis techniques with IBM SPSS version 25 to study the direct and indirect influences of managerial ownership, institutional ownership, and profitability toward IC disclosure. The results of this study show that managerial ownership, profitability and audit committee quality have a significant positive effect on IC disclosure whereas institutional ownership has significant negative effect on IC disclosure. This study also provides empirical evidence, supported by the sobel test, that the audit committee quality is able to mediate the effect of institutional ownership and profitability on IC disclosure. However, the audit committee quality is not able to mediate the effect of managerial ownership on IC disclosure. These findings develop and strengthen the results of prior studies related to the implementation of signaling theory and agency theory in devoting more understanding about IC disclosure.

Purpose: The purpose of this paper was to examine the relationships between clinical practice stress and burnout, and the mediating role of empathy in nursing students. Methods: A cross-sectional research design was employed. One hundred seventeen nursing students completed questionnaires on clinical practice stress, empathy (perspective-taking, fantasy, empathic concern and personal distress) and burnout in December 2017. IBM SPSS Statistics 23 was used and descriptive statistics, frequency, Pearson correlation coefficient and multiple regression were conducted. Baron & Kenny method and Sobel test were adopted for analysis of the mediation effect (personal distress of empathy). Results: The mean scores of clinical practice stress and burnout were 3.45 and 43.09, and perspective-taking, fantasy, empathic concern and personal distress of empathy were 2.67, 2.42, 2.64 and 2.19, respectively. The highest relationship between clinical practice stress and empathy was personal distress of empathy (r=.32, p<.001). Burnout was positively associated with clinical practice stress and personal distress of empathy (r=.22, p=.015; r=.51, p<.001). Personal distress of empathy demonstrated a complete mediating effect on the relationship between clinical practice stress and burnout (Z=3.22, p=.001). Conclusion: These results showed that decreasing personal distress of empathy is important for nursing students, and may help in reducing clinical practice stress and burnout.

Purpose: This study examines the relationships among perceived stress, humor style, responding humor and depression among college students and the mediating effect of humor between perceived stress and depression. Method: During the period May 6-16, 2013, a convenience sample of 200 subjects was obtained from college K in city G. Data analysis was performed by Pearson's correlation coefficients and regression analysis. Results: The average BDI score was 7.7. There were 40 (20.0%), 16 (8.0%), 8 (4.0%), and 11 (9.0%) students with mild, moderate, and severe depression, respectively. The group with depressive symptoms constituted 3.5% of students. There was a significant positive correlation between negative stress perception and depression. Conversely, there was a significant negative correlation between adaptive humor style and negative stress perception. Ultimately, there were significant negative correlations between positive stress perception, adaptive humor style, maladaptive humor style, responding humor and depression. To test the mediating effect of adaptive humor style in the relationship between negative stress perception and depression, a Sobel test was performed and Z-score of 1.7736 (p=.076) obtained. Conclusion: Though the mediating effect of an adaptive humor style on the relationship between perceived stress and depression was not significant, considering the negative correlation with depression, strategies to increase an adaptive humor style and responding humor is recommended to prevent depression in college students.

Purpose: This study sought to investigate health behavior (HB) and its affecting factors based on Anderson's behavioral model in Lao People's Democratic Republic (PDR). Also, it attempted to identify the mediation of the health locus of control (HLC) between HB and the affecting factors. Methods: Secondary data from 694 people without noncommunicable diseases (NCDs) from a survey conducted by the Ewha Womans and the Laos University were used. The measurements included predisposing, enabling, and needs factors, HLC, HB (current non-smoking, low-risk drinking, physical activity, fruit and vegetable consumption, medical checkup). The mediating effect was analyzed using Baron and Kenny's method and the Sobel test. Results: Predisposing (gender, educational level, ethnic), enabling (social support, item ownership in household) and the needs factors (body mass index) were affecting HB. Internal HLC had a positive influence on HB. The stronger the others and chance HLC, the lower the HB. Chance HLC mediated the relationship between the educational level and HB. Conclusion: There is a need to recognize the importance of chance HLC as a mediator between the educational level and HB. Through this result, high-quality nursing education for the prevention of NCDs should be developed considering the impact of chance HLC.
