One of reasons for introducing Building Information Modeling (BIM) is to support clash detection tasks by means of a 3D product model. In the conventional construction project process, clashes have been found during construction phase. However, it can cause cost overrun and time delay. In order to investigate and correct clash detections at design phase, relevant business process and guide for this task should be provided. This study aims to identify hindrances in clash detection tasks at the design phase and analyze its current process using IDEF0 model. Despite the convenience of IDEF0 as a systems analysis tool, professional participants might have difficulties to understand their own tasks according to business process. For this reason, in this research, Business Process Model and Notation (BPMN) is introduced to provide ideal process and required decision making governance. The provide BPMN model will provide insights for a BIM-based collaborative environment to enhance the constructability through the construction project.

A growing number of studies have examined the relevance and impact of social media in building organizational resilience, which the ability to recover from a crisis, in the field of emergency management. However, few studies have assessed how these emergency response organizations perceive their own use of social media in crisis situations. In attempting to fill this gap, this study conducted a structured survey with emergency-response organization representatives in Seoul, South Korea, to examine how such organizations evaluate their utilization of social media in an urban emergency situation and how their social media uses are related to promoting organizational resilience during adverse events such as a flood. Overall, the findings imply that organizations are not yet taking full advantage of social media. Respondent evaluations of their own social media use in all three assessment areas-information provision, information dissemination, and emotional messages-were not satisfactory. However, their perceptions of how well they utilize social media were positively related to how they view their organizational resilience. Therefore, it may be that these organizations realize the powerful role of social media in building organizational resilience but lack the knowledge and experience to make the best use of social media services.

The paper investigates the mechanism through which corporate credit ratings affect dividend payments by decomposing the mean difference of dividends into a part that is explained by the determinants of dividends and a residual part that is contributed by the pure credit group effect, in the framework of the traditional dividend model of Fama and French (2001). Historically, better credit rated firms have shown consistently higher propensity to pay dividends especially during the economic crisis period. According to the counter-factual decomposition technique of Jann (2008), better rated firms are more responsive to the firm characteristics that have positive impact on dividends and poor rated firms are more responsive to the negative dividend predictors. As a result, good (bad) credit ratings make corporate managers become more bold (timid) in their dividend payments and they tend to pay more (less) dividends than what their firm characteristics prescribe. The degree of information asymmetry increases for the poor group firms during crisis periods and they attempt to reserve more cash in preparation for future investments. The decomposition results suggest that the credit group effect can potentially exceed the effect of firm characteristics because firms of different credit ratings can respond to the very same firm characteristics in a different manner.

The aim of this study is to estimate the impact of ownership structure on the performance of listed firms in transition economy. Buiding upon agency theory, hypotheses on such relationship are proposed. A detailed panel data of 502 non-financial companies listed on Ho Chi Minh Stock Exchange and Hanoi Stock Exchange over the period from 2013 to 2018, and the system generalized method of moment estimation are employed to test the proposed hypotheses. To ensure the reliability of data, this study excludes companies that violate information disclosure regulations or that are subject to special supervision by the State Securities Commission of Vietnam. Some firms with inadequate information, firms that lack the financial data required for creating variable or firms that have inconsistent construction are also re-screened. We only collect the data of enterprises that have ownership structure of two or more components. Estimation results reveal that state ownership has an U-shaped relationship with the performance of Vietnamese listed firms, while foreign ownership and the degree of ownership concentration have an inverted U-shaped relationship with listed firms' performance. The article provides governance implications that Vietnamese listed firms should decrease state ownership and foreign ownership to improve firm performance in order to boost investors' confidence.

It was 1976 when the preparation of consolidated financial sheet was first prescribed in this nation. Since then, the prescription has been revised several times. Revised in April 1992, enforcement regulations of the Securities Exchange Act provided that every listed corporation has its consolidated financial sheets and an auditor's opinion about them attached to its business report. In other words, the outside audit of consolidated financial sheets became inevitable. The Act of the Outside Audit of Corporation was revised in December 1993 to provide that all corporations must prepare consolidated financial sheets and receive the outside audit of the documents beginning their settlement of accounts in December 1994. In case of overseas corporations, consolidated financial sheets and the Equity Law have been applied since their settlement of accounts in December 1995. Now those sheets must be prepared by all local and overseas corporations that involve relations of governance or dependence. The preparation and public notification of consolidated financial sheets has been settled as a system. This nation has not yet introduced consolidated tax return using consolidated financial sheets. Such tax return system is already being used by most of the world's economic powers such as U.S., Europe and Japan. This study shows that reduction in corporation tax is the biggest reason for avoiding consolidated tax return system, even though the system can facilitate the settlement of consolidated accounting. Consolidated tax return, which is being implemented in about 20 countries including U.S., needs to be introduced by this nation where consolidated financial sheets are publicly notified.

The purpose of this paper is to analyze the administrative system and legislation of Canada's libraries with priority given to public library. Canada is a constitutional monarchy, a federal state and parliamentary democracy with 10 provinces and 3 territories and two systems of law(civil law and common law). There are about 1,045 public libraries in total and its governance and legislation is a provincial responsibility. For that reason. federal government did not legislate on public libraries and library act is the provincial public library statute authorizing the establishment and operation of public libraries and their management by boards. In Canada. each provincial library act provides for four types of public libraries : municipal libraries, regional libraries, districts libraries, and integrated public library systems.

This paper specifically delineated the methodological application of constructivism in smart tourism studies. It explained what constructivism is and how this methodology could be applied in the study of smart tourism. In this study, residents of Seoul participated in constructivist research using the Q method to identify their subjectivities toward Seoul based on photographs most commonly found in tourism promotional material. Residents are concerned with good governance and cultural integrity, and they are aware of their role as stakeholders in tourism in their communities. However their potential contribution to destination image formation has been usually overlooked by researchers and marketers. Three clusters of subjectivities were revealed after 42 photographs of Seoul were sorted by 37 respondents. The results show how respondents perceived Seoul's destination image. The three clusters agreed that symbolic monuments were the key representations of Seoul. The paper recommends that tourism marketers and policy makers should focus on understanding and coordinating with residents' perceived image of Seoul as a destination when planning and decision making, especially in promoting Seoul as a destination market. This study, in conjunction with other constructivist research offers insight into how destination image is, especially with the rise of smart tourism, a complex social construction.
