The purpose of this study was to examine the role of profitability as a mediating variable in influencing firm value. This study uses a sample of manufacturing companies listed on the Indonesia Stock Exchange from 2016 to 2018. The data used is panel data, with data analysis using multiple regression. Based on the Sobel test, profitability plays a role in mediating the effect of firm size on firm value. The effect of firm size on firm value is indirect, however, through profitability. Therefore, the market price of the shares of large-scale companies will increase if the resulting profitability is high. The capital structure and managerial ownership directly influence firm value. The results showed that managerial ownership and firm size had a positive effect on profitability, while capital structure had no effect on profitability. Capital structure and managerial ownership have a negative effect on firm value, while firm size and profitability have a positive effect on firm value. The main finding of this study is that profitability acts as an intervening variable in mediating the relationship between firm size and firm value.

본 연구는 부모의 방임 및 학대와 청소년의 학교생활적응 사이의 관계에서 자아탄력성의 매개효과를 확인하기 위하여 시행되었다. 이를 위해 "한국아동청소년패널조사"의 초 4패널 4차년도 중학교 1학년 2,092명의 데이터를 사용하였다. 자료 분석을 위해 기술적 통계, Pearson 상관계수 및 위계적 회귀분석을 실시하였고, 매개효과의 유의성 검증을 위해 Sobel test를 실시하였다. 연구 결과는 다음과 같다. 첫째, 부모의 방임 및 학대는 청소년의 학교생활적응에 부정적인 영향을 미치는 것으로 나타나 부모의 방임과 학대를 경험한 청소년은 학교생활적응이 낮음을 알 수 있었다. 둘째, 부모의 방임과 학교생활적응 간의 관계에서 자아탄력성은 부분매개 효과를 갖는 것으로 나타났다. 셋째, 학대와 학교생활적응 간의 관계에서 자아탄력성은 부분 매개효과를 갖는 것으로 나타났다. 이러한 연구결과는 부모의 방임과 학대를 경험하고 있는 청소년들의 학교생활적응을 위해서는 부모의 방임과 학대를 감소시키고, 청소년들의 자아탄력성을 증진시키기 위한 노력이 가정, 학교 및 지역사회에서 필요함을 시사한다.

Purpose - This study empirically validates the theoretical argument of the effect of authentic leadership on organizational citizenship behavior, and the mediating roles of followers' self-awareness and psychological ownership between authentic leadership and followers' organizational citizenship behavior. Research design, data, and methodology - A total of 380 office workers in Korea were surveyed through on-line, and the result was analyzed using confirmatory factor analysis and structural equational modeling. Results - The authentic leadership was shown to be related positively to followers' self-awareness and psychological ownership, both of which were associated positively with their organizational citizenship behavior. The complete mediating effects of followers' self-awareness and psychological ownership were verified between authentic leadership and follower's organizational citizenship behavior. Conclusions - While followers' self-awareness was rarely studied in the authentic leadership study to date, it was found to play a role in the authentic leadership process into organizational outcome. It is argued that the followers' self-awareness as a mediating role between authentic leadership and organizational outcome seems to be more appropriate than the leader' s identification of previous thesis in explaining the authentic leadership effect.
