Korean Executive Trust, Social Responsibility, and Financial Performance: A Moderated Mediation Model

Sumi Jang 강원대학교 경영경제연구소 2021 Asia-Pacific Journal of Business Vol.12 No.1

Purpose - The purpose of this study is to explore the impacts of Korean executives’ trust on a firm’s corporate social responsibility (CSR) activities and corporate financial performance (CFP), which depends on their individual social responsibility (ISR). Design/methodology/approach - A survey was conducted, and 273 Korean executives were recruited. I used SPSS version 25.0, AMOS version 26.0, SmartPLS version 3.2., and PROCESS Macro 3.4. to analyze the moderated mediation model. And, the Structural Equation Modelling (SEM) was employed to confirm the proposed relationships in the model. Findings - The results show that Korean executives’ trust is positively related to CSR. I also found that Korean executives’ trust is positively related to CFP. Moreover, I found that there is a mediating effect of a firm’s CSR activities on the trust-CFP relationship. However, I didn’t find conditional indirect and direct effects on the relationships among the proposed constructs. The findings overall suggest that Korean executives’ trust is such an important mechanism that will affect firm-level CSR and CFP. Research implications or Originality - Although prior studies reveal that executives’ trust in their subordinates positively influences cooperation, creativity, and innovation among subordinates in a team, it is still unclear whether executives’ trust in their employees or strangers impacts firm-level CSR and CFP. Moreover, not many studies examined the mediating effect of CSR on executives’ trust and CFP especially in the Korean context. Therefore, this study intends to fill the knowledge gap by focusing on South Korea. This study also contributes to extant CSR and trust literature, and practically contributes to executives, policy makers, and practitioners in South Korea.

Korean Executives’ Religiosity, Corporate Social Responsibility (CSR) Attitude and Behavior

Sumi Jang 한국전문경영인학회 2020 專門經營人硏究 Vol.23 No.4

심리경제학 및 행동경제학에서 태도와 행동의 차이가 생기는 이유에 대한 연구가 많지만, 개인의 종교성을 태도와 행동의 차이에 영향을 주는 요인으로 보는 연구는 거의 없다. 많은 연구들은 태도와 행동의 차이에 영향을 주는 요인으로 개인적 가치, 도덕적 가치, 윤리적 의무 등을 조사해 왔다. 게다가, 한국에서는 많은 사람들이 종교를 가지고 있는데, 이것은 한국인의 사고방식과 기업의 사회적책임이 일치하는 경향이 있다는 것을 말해준 다. 그러므로, 기업의 사회적책임과 관련된 태도와 행동의 차이에 대한 한국 경영인의 동기는 무엇인지 조사해 볼 필요가 있다. 가치-태도-행동 모델을 바탕으로, 이 연구는 한국 경영자 개인의 종교성이 그들의 기업의 사회적책임에 관한 태도와 행동에 주는 영향 을 조사한다. 이 연구의 결과는 한국 경영인의 종교성과 기업의 사회적 책임에 관한 행동 사이의 관계에서 기업의 사회적 책임에 관한 태도가 부분적으로 매개효과가 있다는 것을 보여주며, 개인의 종교성이 기업의 사회적 책임에 관한 태도를 통해 행동에 영향을 준다는 것을 주장하는 바이다. 이 연구는 기업의 사회적 책임에 관한 연구와 사회 심리학적 연구 에 기여하며, 한국 경영자의 종교성과 기업의 사회적 태도와 행동에 관련된 관계성을 연구함으로, 한국기업 및 한국 사회에 기여한다. While there has been a lot of investigations of reasons behind the gap between attitude and behavior in the economic psychology or behavioral economic literature, only a few studies looked at an individual’s personal religiosity as a factor that can explain the gap between attitude and behavior. Moreover, there are many people who have religion in South Korea, and corporate social responsibility (CSR) tends to be in line with the mentality of Korean people. Therefore, it is important to investigate the motivations of Korean managers that result in the gap between their attitude and behavior towards CSR. Drawing on the value-attitude-behavior (VAB) model, this paper elaborates the influences that the personal religiosity of Korean executives have on their CSR attitude and behavior. The results of this study show that there mostly is a partial mediation impact of CSR attitude on the relationship between Korean executives’ religiosity and CSR behavior. This research adds to the CSR literature and the social psychology literature, and also practically contributes not only to business settings in South Korea but also to Korean society in general.

CHARACTERIZATIONS OF GABOR FRAMES

Sumi JANG,Byeongseon JEONG,Hong Oh KIM 한국산업응용수학회 2009 한국산업응용수학회 학술대회 논문집 Vol.2009 No.5

For positive integers N, M ∈ N, let gn, ∈ L²(R) with supp(Dbgn) ∪ supp(Dbgn) ⊂ [0, M], where Dbg(t) := b<SUP>?1/2</SUP>g(t/b), b > 0 and n = 1, 2, ...,N. We give another set of necessary and sufficient conditions for the multiwindow Gabor system (GN; a, b) := {gn;k,l(t) := gn(t ? ka)e<SUP>2πilbt</SUP>}n=1,...,N; k,l∈Z and the corresponding Gabor system (GN; a, b) to form a pair of dual frames for the rational sampling ab = P/Q with P,Q ∈ N, in addition to the Zibulski-Zeevi and Janssen conditions. The conditions come from the back transform of Zibulski-Zeevi condition to the primal domain but are more informative for the applications. As an applications, we show that the Gabor system (GN; 1, 1) forms an orthonormal basis for L²(R) if and only if N = 1 and |g₁(t)| = ∑M?1m=0 xm+Em(t) a.e. where {Em m=0,...,M?1 forms Lebesgue measurable partition of the unit interval [0, 1). Our criterions provides a rich family of multiwindow dual Gabor frames and multiwindow tight Gabor frames for L²(R) for the particular choices of P, Q, N, M ∈ N.

CONSTRUCTION OF A NON-STATIONARY BIORTHOGONAL WAVELET SYSTEM USING A SUBDIVISION SCHEME

Sumi JANG,Jungho YOON,Hong Oh KIM 한국산업응용수학회 2007 한국산업응용수학회 학술대회 논문집 Vol.2 No.1

We present the 4-point Gaussian based non-stationary interpolatory subdivision scheme which approximates the given data in the span of translations for the Gaussian function with the parameter λ. Different choice for the parameter leads to a different set of masks. The sequence of the refinable functions converges to the refinable function for the 4-point Deslauriers-Dubuc scheme in L<SUP>p</SUP>(0 < p < ∞). Using the subdivision mask as the lowpass filter, we construct the non-stationary biorthogonal Multiresolution Analysis(MRA) which has the approximation order of 4. Then we derive the corresponding non-stationary biorthogonal wavelet system. The resulting scaling functions and the wavelets are symmetric and compactly supported.

The Effect of Corporate Social Responsibility on Religiosity, Individual Social Responsibility, and Corporate Financial Performance in South Korea

Sumi JANG 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.8

The study investigates the mediating effect of Korean firms’ corporate social responsibility (CSR) in the relationship between Korean executives’ religiosity, their individual social responsibility (ISR), and corporate financial performance (CFP). As executives lead the firms’ strategies and policies, their religiosity or ISR may have a significant influence in attaining the firm’s CSR and influencing CFP. The upper echelon theory, agency theory, and stakeholder theory are used to explain the link between individual-level drivers of CSR, a firm’s CSR, and CFP. The upper echelon theory, agency theory, and stakeholder theory are integrated into the conceptual model, which explains the relationships between proposed constructs in this study. This study employs survey data of 421 Korean companies. The confirmatory factor analysis (CFA) technique was used to test the proposed hypotheses. The main result shows that Korean executives’ religiosity and their ISR positively influence CFP when mediated by CSR. The findings of this study suggest that Korean executives’ personal values such as their religiosity and ISR can impact the firm’s CSR activities or financial performance. Overall, this paper responds to the recent calls in the CSR literature to examine the individual-level drivers from non-western contexts by shedding more light on the Korean context.

NON-STATIONARY BIORTHOGONAL WAVELET SYSTEMS CONSTRUCTED FROM INTERPOLATORY SUBDIVISION SCHEMES

Sumi JANG,Hong Oh KIM,Yeon Ju LEE,Jungho YOON 한국산업응용수학회 2007 한국산업응용수학회 학술대회 논문집 Vol.3 No.2

Interpolatory non-stationary subdivision schemes reproducing a certain class of basis functions are used to present the refinable functions and the assocaited dual functions. It generalizes the known interpolatory refinable functions reproducing polynomials. The new refinable functions are based on exponential polynomials and the integer shifted Gaussian functions respectively. With these refinable functions at hand, we construct the orthogonal and biorghogonal wavelet system. Our ultimate future goal is to perform the associated mathematical analysis including regularity, stability, and vanishing moments as well.

대학생의 성인애착과 대인관계 유능성의 관계에서 정서표현의 매개효과

장수미(Jang, Sumi),이동훈(Lee, Donghun) 한국재활심리학회 2021 재활심리연구 Vol.28 No.3

본 연구는 초기 성인기에 해당하는 대학생을 대상으로 성인애착과 대인관계 유능성의 관계에서 정서표현의 매개효과를 확인하고자 하였다. 이를 위해 전국의 대학생 286명을 대상으로 성인애착척도, 대인관계 유능성척도, 정서표현척도에 관해 수집된 자료를 분석에 활용하였다. 정서표현이 성인애착 및 대인관계 유능성과의 관계에서 매개하는지 살펴보기 위해 구조방정식을 통해 매개모형을 검증하였다. 연구의 결과를 요약하면 다음과 같다. 첫째, 애착불안이 대인관계 유능성으로 가는 직접 경로를 제외한 모든 경로들이 유의미한 것으로 나타났다. 둘째, 애착불안과 대인관계 유능성의 관계에서 정서표현이 완전매개하고 있는 것으로 나타났다. 셋째, 애착회피는 대인관계유능성에 직접 영향을 미치거나 정서표현을 매개로 간접 영향을 미쳤다. 이를 통해 성인애착(애착불안, 애착회피)과 대인관계 유능성의 관계에서 정서표현의 영향력을 확인할 수 있었다. 결론적으로, 이러한 결과는 대학생들의 대인관계 유능성을 향상시키기 위한 개입 프로그램을 설계할 때 정서표현을 고려하고 검토해야 함을 보여주었다. 연구의 결과를 바탕으로 시사점과 연구의 제한점 및 후속연구를 위한 제언을 논의하였다 The purpose of this study was to investigate the mediating effect of emotional expression on the relationship between adult attachment and interpersonal competence for college students. A sample of 286 college students were asked to complete the Adult Attachment Scale, the Interpersonal Competence Scale, and the Emotional Expressivity Scale. Results are as follows: First, the examination of structural relations among the major variables showed that all of the paths were significant, except for the direct path from attachment anxiety to interpersonal competence. Second, it was found that emotional expression fully mediates the relationship between attachment anxiety and interpersonal competence. Third, attachment avoidance had direct effect on interpersonal competence, or it had indirect effect on interpersonal competence via the mediated path of emotional expression. These findings suggest that emotional expression plays an important role in the relationship between adult attachment and interpersonal competence. The limitations of the present study and the implications for further research are discussed.
