Purpose: This research aims to investigate the impact of corporate integrity on stock price crash risk. Research design, data, and methodology: Taking 1419 firms listed in Shenzhen Stock Exchange in China as a sample, this paper empirically analyzed the relationship between corporate integrity and stock price crash risk. The main integrity data was hand-collected from Shenzhen Stock Exchange Website. Other financial data was collected from CSMAR Database. Results: Findings show that corporate integrity can significantly decrease stock price crash risk. After changing the selection of samples, model estimation methods and the proxy variable of stock price crash risk, the conclusion is still valid. Further research shows that the relationship between corporate integrity and stock price crash risk is only found in firms with weak internal control and firms in poor legal system areas. Conclusions: Results of the study suggest that corporate integrity has a significant influence on behaviors of managers. Business ethics reduces the likelihood of managers to overstate financial performance and hide bad news, which leads to the low likelihood of future stock price crashes. Meanwhile, corporate integrity can supplement internal control and legal system in decreasing stock price crash risks.

Generic medicine (GM), which is an alternative drug product for branded medicine (BM), is used less in Japan than in other OECD countries. Therefore, we investigate why the medical consumers of Japan avoid the use of GMs even though the efficacy and safety of the medicines have already been proven. We theorize that effectiveness or risk of GMs are related to the consumer attitude toward GMs is affected by the behavioral approach/activation system (BAS) which promotes actions to reach the desired state, and the behavioral inhibition system (BIS) which suppresses behaviors to avoid negative outcomes. To see which of the BAS and BIS dimensions are related to GM usage, we surveyed 374 Japanese consumers and found that Quality, Efficacy, Safety, & Cost-effectiveness with the BAS, and Functional Risk, Financial Risk, Social Risk, Physical Risk, Psychological Risk, & Time Risk with the BIS had a significant effect on consumer attitude to GMs. These results are important in that they 1), confirm the role of BAS/BIS in attitudes to GMs, 2), provide guidelines when marketing GMs, 3), help governments promote the use of GMs as a cost-saving measure, and 4), guide future surveys regarding consumer attitudes to GMs.

This paper illustrates a new nodal effective load model for nodal probabilistic production cost simulation of the load point in a composite power system. The new effective load model includes capacities and uncertainties of generators as well as transmission lines. The CMELDC based on the new effective load model at HLII has been developed also. The CMELDC can be obtain from convolution integral processing of the outage capacity probabilistic distribution function of the fictitious generator and the original load duration curve given at the load point. It is expected that the new model for the CMELDC proposed. In this study will provide some solutions to many problems based on nodal and decentralized operation and control of an electric power systems under competition environment in future. The CMELDC based on the new model at HLII will extend the application areas of nodal probabilistic production cost simulation, outage cost assessment and reliability evaluation etc. at load points. The characteristics and effectiveness of this new model are illustrated by a case study of a test system.

In this paper, we provide an overview of financial development in Vietnam. Particularly, a new approach of this study is to measure financial development through improvements in depth, efficiency and access of the banking system and stock market. Further, the study examines the factors significantly affecting financial development in Vietnam. The data are collected in Vietnam, an emerging country with a limited financial development. We employ the Autoregressive Distributed Lag (ARDL) approach, which generates a high reliability and suits data characteristics of emerging countries like Vietnam. We observe that Vietnam's banking system plays a key role in supplying credits to the economy while the nascent stock market at a limited size shows its potential for a considerable growth in the future. We also find the influential determinants of financial development in Vietnam including real estate market (RE), economic growth (EG), consumer price index (CPI), and global financial crisis (GFC). These findings are essential for Vietnamese authorities in providing practical solutions in order to build a sustainable and synchronous financial development. They are also first empirical evidence relating to an overview of financial development in an emerging country, so they are not only valuable to Vietnam but also crucial to other emerging economies.

This work firstly aims to analyse how the policy makers had been able to sort out the two policy issues, 'how did the MOST establish the inter-departmental project' and 'why did the MOST give a legal power to the private experts', in the process of policy making for Highly Advanced National(HAN) project, called G7 Project, which had been implemented for 10 years in 1990s. Then, this will discuss the policy implications available to the similar policy areas in the future. The result shows that the agenda setting of the G7 Project, one of the successful national R&D projects in Korea, had been initiated by a few leaders who had have the perspective of pioneer. In addition, this explains that private experts had more played than civil servant did in the process of policy formation, which had been backed up by the R&D plannin4g system then introduced in R&D management process for the frist time. This case study will provide policy makers with the opportunities to remind 'the necessities of the policy management by the system not actors', 'more effective management of distribution policy' and 'the better role of related experts in the policy making process'. Also, above issues will make both the practitioners and the researchers again consider how to improve the rationality and effectiveness of the policy making process in the field of science and technology.

At present, companies write daily work record or use bar-code in order to collect distribution flow data in real time. However, it needs additional works to check the record or read the bar-code with a scanner. In this case, human error could decrease accuracy of data and it would cause problems in reliability. To solve this problem, RFID (Radio Frequency Identification) is introduced in many automatic recognition sector recently. RFID is a technology that identification data is inserted into micro-mini IC chip and recognize, trace, and manage object, animal, or person using wireless frequency. This is being emerged as the core technology in future ubiquitous environment. This study is intended to suggest RFID application method in franchise business. Traceability and visibility of individual product are supplied based on EPCglobal network. It includes DW system which supplies various assessment data about product in supply chain, financial transaction system which is based on product transaction and position information, and RFID middleware which refines and divides product data from RFID tag. With the suggested application methods, individual product's profile data are supplied in real time and it would boost reliability to customer and make effective cooperation with existing operation systems (SCM, CRM, and e-Business) possible.
