This study focuses on the evacuation and recovery problem (ERP), which is modeled by graphs. The model provides support for the design of exact and fast and practically convenient algorithms. The ERP is viewed as a constrained longest path problem in a graph whose objective is to maximize the total profit under resource and information constraints. This study develops an exact algorithm and a new fast epsilon-approximation algorithm (FPTAS), which are proved to be efficient with respect to the time complexity. Finally, some open questions are proposed for future research.

The purpose of this study focuses on the extent to which the image of Macanese gastronomy tourism and electronic word of mouth influences tourists' intentions, based on samples of those who use the Internet to search for information about Macanese gastronomy. Questionnaires were distributed to visitors to Mainland China by means of the Internet. The findings revealed that electronic word of mouth and the image of Macanese gastronomy tourism obviously indicated positive effects, suggesting that both are leading factors in attracting tourists, therefore boosting the travel industry in Macau. The findings also provided evidence for the Macau Government tourism office and website operators to effectively promote the image of gastronomy tourism in Macau. Additionally using the Internet to motivate tourists to travel for gastronomy reasons could create a reasonably valid construct to use for market segmentation purposes.

The Health Information Technology for Economic and Clinical Health Act (the HITECH Act of 2009) was enacted in 2009 to speed up the adoption of Electronic Health Record (EHR) systems among the healthcare providers in the USA, however the standards of Meaningful Use of EHR was not released until July 2010. This study uses Difference-In-Difference model to analyze the revenue growth rate of EHR software developers and finds that the HITECH Act of 2009 delayed the revenue growth of EHR firms until 2011.

The study of interest rate volatility is important for both asset pricing and financial risk management. To depict the heteroskedastic characteristic of interbank offered rate, we establish a basic SV model and estimate the parameters using a typical MCMC numerical approach named Gibbs sampling. From the empirical analysis of SHIBOR, it is concluded that the persistence of volatility is significant, however, less than the stock market, indicating the auto correlations of volatility in lending market decay more quickly.

The study investigates the role of trust in customer service attributions. Using two experiments based on scenarios of having a haircut and visiting a restaurant, data are collected for analyzing how perceived trust to the service provider impact the ways that customers attribute their service experiences. A field survey has also been designed to test the robustness the findings of the two experiments in real service setting. The findings of the studies support the effect of trust on customer service attributions. Compared to low trust customers, high trust customers are more likely to attribute negative service experiences to external, uncontrollable, and unstable factors, and attribute positive service experiences to internal, controllable, and stable causes.

In order to have one set of accounting regulations around the world, the Securities Exchange Committee (SEC) in the United States (US) asked the International Accounting Standards Board (IASB) to work in conjunction and attempt to minimize the differences between the International Financial Reporting Standards (IFRS) and Generally Accepted Accounting Principles in the United States (US GAAP). The two different sets of standards, IFRS and US GAAP, generate a lot of differences in various fields, such as financial statement presentation, revenue recognition, business combinations, etc. This paper introduces the history of the convergence between US GAAP and IFRS. In addition, this paper also summarizes the advantages and disadvantages to investors and companies regarding to the convergence. Finally, it concludes that such analysis will allow users and accounting majors to better evaluate and understand the impact of the convergence.

Corporate value is attributed from financial capital and intellectual capital. Intellectual capital is knowledge and capability of employees, which benefits for raising operation performance. This study aims to examine the impact of intellectual capital on corporate value of casino industry in Macau listed in the Hong Kong Stock Exchange based on Value Added Intellectual Coefficient (VAIC) model using semiannual data of the period form January 2009 to June 2012. The finding of this study is that financial capital has a significantly positive relationship with corporate value whereas intellectual capital has positive relationship but is not significantly related to corporate value.

This paper investigated the antecedents and influence factors of Macao residents' acceptance intention of Sport Easy Program. Using data obtained from 459 interviewers, regression analysis revealed that acquaintance, convenience, facilities, and athletics habit have positive impacts on the acceptance intention, while gender, age, and education have different moderating effects on these relationships. These findings deepened insights into the unified theory of acceptance and use of technology (UTAUT) as well as the ways for the Macao SAR government to improve the public health administration.

Dynamic Time Warping (DTW) is a powerful technique in the time-series similarity search. However, its performance on large-scale data is unsatisfactory because of its high computational cost. Although many methods have been proposed to alleviate this, they are mostly indirect methods, i.e, they do not improve the DTW algorithm itself. In this paper, we propose to incorporate the Ordered Graph Search (OGS) and the lower bound for DTW into an improved DTW algorithm and apply it on time series data. Extensive experiments show that the improved DTW algorithm is faster than the original dynamic programming based algorithm on multi-dimensional time series data. It is also especially useful in the post-processing stage of searching in large time series data based on DTW distance.
