Macau's casino sector has been expanding rapidly, particularly targeting mainland Chinese gamblers. The novelty and under-researched nature of this market is a challenge for Macau's casino and destination marketers. This study explores the characteristics of the mainland market and compares this with the second placed and more mature Hong Kong market. The profiling of visitors from Macau's main source markets including demographic, region of origin, trip behaviour and motivation characteristics provides insights into the future success of the destination. Adaption theory is used to explain the implications of differences between Gambling and Non-Gambling visitors from the two source markets. © 2012 John Wiley & Sons, Ltd.

This study was to determine the effects of five-week high-intensity interval training (HIIT) on cardiorespiratory fitness, body composition, blood glucose, and relevant systemic hormones when compared to moderate-intensity continuous training (MICT) in overweight and obese young women. Methods. Eighteen subjects completed 20 sessions of HIIT or MICT for five weeks. HIIT involved 60 × 8 s cycling at 90% of peak oxygen consumption (V - O 2 p e a k) interspersed with 12 s recovery, whereas MICT involved 40-minute continuous cycling at 65% of V - O 2 p e a k. V - O 2 p e a k, body composition, blood glucose, and fasting serum hormones, including leptin, growth hormone, testosterone, cortisol, and fibroblast growth factor 21, were measured before and after training. Results. Both exercise groups achieved significant improvements in V - O 2 p e a k (+7.9% in HIIT versus +11.7% in MICT) and peak power output (+13.8% in HIIT versus +21.9% in MICT) despite no training effects on body composition or the relevant systemic hormones. Blood glucose tended to be decreased after the intervention (p = 0.062). The rating of perceived exertion in MICT was higher than that in HIIT (p = 0.042). Conclusion. Compared with MICT, short-term HIIT is more time-efficient and is perceived as being easier for improving cardiorespiratory fitness and fasting blood glucose for overweight and obese young women. © 2016 Zhaowei Kong et al.

For an undirected complex network made up with vertices and edges, we developed a fast computing algorithm that divides vertices into different groups by maximizing the standard "modularity" measure of the resulting partitions. The algorithm is based on a simple constrained power method which maximizes a quadratic objective function while satisfying given linear constraints. We evaluated the performance of the algorithm and compared it with a number of state-of-the-art solutions. The new algorithm reported both high optimization quality and fast running speed, and thus it provided a practical tool for community detection and network structure analysis. © 2014 Wenye Li.

Global Policy | Year: 2014

While pursuing high economic growth, policy makers must be ready to bear the high economic risk accompanying that growth. The best policy is to find a realistic combination where the needed economic growth is pursued with controllable financial fluctuation. © 2014 University of Durham and John Wiley & Sons, Ltd.

This paper presents a few design considerations in implementing building block-based Computer Aided Design (CAD) for analog switched circuits. The considered synthesis include four independent levels: 1) system level, 2) building block level, 3) circuit simulation level, and 4) layout generation, which multistage can separate a larger size circuit into a few major basic building blocks. The aim of this paper is to show how to integrate a few existing programs to shorten the design period, from the user friendly interfacing to the corresponding building blocks. A CAD tool for Switched Capacitor (SC) analogue circuit is shown briefly. © 2012 IEEE.

This paper presents an overview of the recent advances in design of switched circuits, from cell-level analog circuits (e.g., op amps) to Switched Capacitor (SC) filters, using constraint-programming modeling. The different adopted optimization approaches in the designs of switched circuits are briefly reviewed and then compared. In the last part of this paper, we will discuss the possible some existing problems in optimization processing. © 2012 IEEE.

This paper describes an analysis of multi-stage and multi-rate IIR switched capacitor (SC) decimators using an interactive switched capacitor multi-rate compiler (ISCMRATE). Motivated by the experimental observations, the purpose of this paper is to explore a portion of characteristics for the multi-stage IIR SC decimators, with their implications in the context of a complete IIR SC filter. To overcome the limitations of conventional multi-stage IIR SC decimators, a novel solution has been introduced for the implementation of a multi-stage IIR SC circuit. Based on the statistical approach of the compiler, we provide the comparative analysis for different IIR SC decimators, including total capacitor area, capacitance spread and arbitrary anti-aliasing amplitude responses with a decimating factor in single and multi-stage building blocks. Examples are given to illustrate the practical feasibility of this compiler. © 2014 World Scientific Publishing Company.

The conventional web proxy servers use hard disk as their primary cache storage. However, as disks use mechanical operations, they are typically the slowest component of the servers. Though, in the last decade, various solutions have been proposed to improve the proxy performance, disks are still the performance bottleneck. Consider that the mainstream operating systems are 64-bit and the cost of memory has become economical in recent years. In this paper, a proxy server using main memory as the primary cache storage is proposed. Analytical results show that the ram-based proxy servers effectively eliminate the performance bottleneck of disk, and allow systems to scale well for higher browser rates.

Proposals for casinos usually focus on numbers of jobs without considering their quality. We surveyed 1,506 Macau residents, modelling happiness and job satisfaction. Being employed is shown to be important for happiness. But job attributes also matter, confirming the work domain as influential on wellbeing. Casino employees report similar happiness as others. However, despite relatively high pay, they report low overall job satisfaction. The particular aspects of their jobs that they rated generally negatively tended to be those inherent in casino employment rather than easily modifiable by managerial action.
