Let (𝓛, 𝒜) be a complete duality pair. We give some equivalent characterizations of Gorenstein (𝓛, 𝒜)-projective modules and construct some model structures associated to duality pairs and Frobenius pairs. Some rings are described by Frobenius pairs. In addition, we investigate special Gorenstein (𝓛, 𝒜)-projective modules and construct some model structures and recollements associated to them.

Duality in the optimal harvesting for a nonlinear age-spatial structured population dynamic model is studied in the framework of optimal control problem. In this paper the duality theory that displays the conjugacy of the primal problem is established and an application is given. Duality theory plays an important role in both optimization theory and methodology and the results may be applied to a realistic biological system on the point of optimal harvesting.

In this paper, a class of nonlinear bilevel programs, i.e. the lower level problem is linear programs, is considered. Aiming at this special structure, we append the duality gap of the lower level problem to the upper level objective with a penalty and obtain a penalized problem. Using the penalty method, we give an existence theorem of solution and propose an algorithm. Then, a numerical example is given to illustrate the algorithm.

This study was intended to define the spatial concept of the boundary structure of the architectural space as well as evaluate the Hyangdan which well represents the features of Korean traditional building in such a way of reviewing the building structure of Korean traditional residential space. The boundary is categorized into visible boundary and invisible boundary which was also functionally classified into the features of isolating, passing, mediating and overlapping. The major elements comprising the boundary structure was analyzed by the characteristic of the pattern so as to define them as the concept of surrounding, duality, hierarchism, continuity and overlapping. Based on such concepts, a boundary structural characteristics of Hyangdan were reevaluated and outlined as follows. The surrounding feature was seen through the outer side of the structure surrounded, two courtyards and eaves, and a duality showing both the closure of main house and openness of detached house was seen through the characteristics of surrounding structure. And the continuous activities toward the inner room and the empty space to link them in a systematic way and repeatedly aligned rooms reveal the overlapping as continuous and transitional space. And finally, an elevated stylobate demonstrates the hierarchical features of the structure.

This study examines the effect of board structure and audit committee structure on financial reporting timeliness among Malaysia's top 100 public listed companies. Specifically, this study examines whether board independence, CEO duality, board ownership, audit committee independence, audit committee competence, and audit committee diligence influence the financial reporting timeliness of the public listed companies. This study selects the top 100 public listed companies by market capitalization listed on the Main Market of Bursa Malaysia as the sample since the main board has more public reprimands on financial reporting timeliness compared to other boards. The content analysis on annual reports for five years from 2015 to 2019 is utilized. The results show that audit committee competence and audit committee diligence significantly affect financial reporting timeliness. In contrast, board independence, CEO duality, board ownership, and audit committee independence have insignificant relationships with financial reporting timeliness. The findings in this study are helpful for compliance analysis and strategy formation in enhancing financial reporting timeliness. This study contributes to the agency theory by providing a new perspective on how different sections of corporate governance features interact together to influence financial reporting timeliness. In addition, the findings can assist the regulators in establishing quality corporate governance.

본 연구에서는 자원의존이론을 이용하여 사외이사 비중과 최고경영자의 이사회 의장직 겸임 효과가 하이테크 산업에 속해 있는 국내 상장기업의 인수합병 성과에 미치는 영향을 2004년부터 2012년까지 수행된 인수합병거래 246개를 대상으로 실증 분석하였다. 분석결과에 따르면, 사외이사 비중은 인수합병 성과에 정(+)의 영향을 미치는 것으로 나타났다. 그러나 최고경영자가 이사회 의장직을 겸임하는 경우 인수합병 성과에 부(-)의 영향을 미치는 것으로 나타났다. 사외이사의 비중과 최고경영자의 이사회 의장직 겸임이 지닌 상호작용의 효과를 살펴본 결과, 최고경영자가 이사회 의장직을 겸임하는 경우 사외이사의 비중이 인수합병 성과에 정(+)의 영향을 미치는 것으로 나타났다. 그러나 이사회 의장이 독립적인 지위를 가지는 경우 사외이사의 비중이 인수합병 성과에 부(-)의 영향을 미치는 것으로 나타났다. 아울러 연구결과의 타당성을 확보하기 위해 상호작용항을 통한 회귀분석 및 다양한 사건기간을 대상으로 실증분석을 수행하여 동일한 결과를 얻을 수 있었다. 최고경영자가 이사회 의장직을 겸임하는 경우 리더십 강화 및 조직 내 지휘체계 확립으로 인해 기업 외부의 이해관계자로부터 정당성을 확보하게 된다. 이를 통해 이사회의 자원의존 기능이 강화되며 인수합병 성과에 긍정적인 영향을 미치는 것으로 해석된다. 반대로 이사회 의장이 독립적인 지위를 가지는 경우 최고경영자의 최고책임자로서의 외부 정당성이 약화된다. 따라서 이사회의 자원의존 기능이 감소되고 인수합병 성과에 부정적인 영향을 미치는 것으로 해석할 수 있다. 기존의 선행연구에서는 최고경영자의 이사회 의장직 분리의 긍정적인 효과에 대해서 주목하였다면, 본 연구에서는 최고경영자의 이사회 의장직 겸임의 긍정적인 효과를 실증적으로 보여주었다는 점에서 그 의의가 있다고 생각한다.

The purpose of this study is to investigate the evolution of regional tourism resources from the perspective of business ecosystem network. A regional tourism structure changes due to various factors such as natural resources, facilities, festivals and events, public resources, and etc. An exploratory analysis was conducted to examine the interaction between resource characteristics and alliance complexity in the regional tourism industry. In the process, the duality of technology provides an insight into the interaction among several players within an alliance network which include regional attractions and tourism industry. As a result. we identified four types of tourism alliance network: functional, organizational, resource-oriented, and artificially-allied. The managerial implications are also discussed.

This research extends the literature on the effect of board characteristics and ownership structure on audit fees; these factors affect the firm's agency costs and how the auditor assesses various risks, hence the audit efforts and fees. The paper introduces political connections as a determinant of audit fees for the first time in Jordan, where the political connection is prevalent and affects decision making on the Jordanian boards. The sample consists of 109 manufacturing and service firms listed on the Amman Stock Exchange (ASE) over the years 2012-2019. Data is obtained from the ASE and the company's annual reports. Board characteristics are measured by board size, independence, leadership duality, meetings frequency, political connections, and audit committee. Ownership structure was measured by concentration, foreign ownership, and Institutional ownership. The study hypotheses were tested by using Generalized Least Squares regression. The Findings showed that larger boards, politically connected firms, and firms with leadership duality are more likely to pay higher fees. Besides, Firms with greater foreign ownership pay less fees, whereas the rest of the variables are insignificant. Results suggest that political connections play a major role in determining audit fees; this provides a recommendation to policymakers in Jordan to reconsider regulations regarding political connections.

This study aims to investigate the effect of the composition of the board and ownership structure on a firm's value in Jordanian firms. Specifically, it aims to determine the effect of board size, (CEO) duality, and family, foreign, institutional, and government ownership on a firm's value. An ordinary least square regression (OLS) was employed to examine the study hypotheses in a sample of 35 Jordanian industrial firms (175 firm-year observation) for a period of five years from 2016-2020. As measured by Tobin's Q (Q ratio) and market-to-book (MB ratio) for Jordanian industrial firms listed on Amman Stock Exchange (ASE). The result found that foreign ownership, institutional ownership, and family ownership have a significant and positive effect on firm value. By contrast, government ownership does not have a significant effect on firm value. With respect to board composition (CEO duality and board size), the study results found no evidence to support the effect of board composition on firm value. The study recommended the concerned authorities with several recommendations, most notably: taking the necessary measures to ensure the continuity and growth of family businesses because of their positive impact on the value of the company and economic growth, spreading awareness about how governance protects the interests of investors.
