天津大跨椭球形展厅结构方案对比与分析

针对天津某大跨椭球形展厅双向钢拱结构和钢-混凝土组合结构2种方案,对比、分析了两种方案的受力性能、刚度特性、经济指标、碳排放等。结果表明,采用钢-混凝土组合结构进行大跨设计时,可保证与双向钢拱结构相当的受力性能,但刚度、经济指标、碳排放量明显优于双向钢拱结构,是此建筑更适合的选择。     

Re-evaluation of global innovation index based on a structural equation model

The Global Innovation Index (GII) was proposed to observe the innovation capability and efficiency levels of individual countries using input and output factors. However, it does not consider potential structural relationships among factors affecting the innovation performance of a country. In this study, we proposed a structural equation model (SEM) based on the hypothesised national innovation structure among seven factors representing inputs (institution, human capital and research, infrastructure, market sophistication, and business sophistication) and outputs (knowledge and technology outputs, and creative outputs). Using GII data from 2013, we discovered that business sophistication and infrastructure have the strongest direct and indirect effects on creative output, respectively. In addition, a new ranking is obtained based on the fitted SEM. We provide feedback information to improve innovation capabilities.

Limitations and Strengths of Pan-Asian Advertising Media: A Review for International Advertisers

Economic growth in Asia has led to a proliferation in the supply of pan-regional media. Most of these are elitist media targeting affluent businessmen and travellers. The increasing importance of the Chinese-speaking market spurs the growth of Chinese language pan-Asian media. The emergence of satellite television networks popularizes pan-regional media to a broader audience, although its penetration is still small in comparison to local media. When selecting pan-regional media for advertising in the region, advertisers are advised to use data from pan-Asian audience surveys, publication audit figures and competitive advertising expenditure reports in examining the cost-efficiency of each media vehicle. In choosing between pan-regional and local media, advertisers should consider the homogeneity and socio-economic status of their target audience, the importance of international recognition and consistency in image for the brand, geographic strengths, and other added values of the media.     

Becoming a founder: How founder role identity affects entrepreneurial transitions and persistence in founding

We develop a new theory that views organizational founding as involving a role transition. Through the construct of founder role identity, we delineate how identity centrality and complexity affect individuals' ability to exit a work role in order to undertake founding activities. We argue that individuals are challenged to adjust to the founder role requirements and incorporate the new role into an overall self-concept. We then delineate how configurations of founder role identities influence persistence, and the longer-term outcomes of dormancy and successful founding.

Information and adjustment in a local housing market

Existing studies on bubbles have been mainly concerned with investigating the stationarity properties of stock prices and market fundamentals. We develop a new method of testing for bubbles that relates the bubble component of stock prices to the probability of bursting in the context of the Weibull distribution. There were several eruptions and subsequent collapses of seeming bubbles over the past three decades: 1987 (Black Monday), 2000 (information technology (IT) boom) and 2007 (housing market boom). Using US monthly data for the S&P 500 and NASDAQ series, we have found that the S&P 500 series contained an explosive bubble only during the boom of the housing market that occurred before the 2007 global economic crisis, and the NASDAQ market contained an explosive bubble during the surge of stock prices peaking in 1987 and 2007, although our stationarity tests fail to detect the bubbles. No bubble was found in both the S&P and NASDAQ series during the 2000 IT boom. Our evidence corroborates the criticism that the traditional unit root and cointegration tests may not be able to detect some important class of bubbles.
