Noisy chaotic dynamics in commodity markets

The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003     

Order imbalance and stock returns: Evidence from China

We investigate the relation between daily order imbalance and return in the Chinese stock markets of Shenzhen and Shanghai. Prior studies have found that daily order imbalance is predictive of subsequent returns. On the two Chinese exchanges we find the autocorrelation in order imbalances is similar to that of the New York Stock Exchange as reported by Chordia and Subrahmanyam [Chordia, T., & Subrahmanyam, A. (2004). Order imbalance and individual stock returns: Theory and evidence. Journal of Financial Economics, 72, 485–518]. We also find a strong contemporaneous relation between daily order imbalances and returns. However, we do not find evidence that order imbalances predict subsequent returns. We attribute the difference in predicative power to differences in trading mechanisms on the two exchanges and to differences in the share turnover rates.     

To Screen or Not to Screen? Using the Internet for Selection Decisions

Organizations are increasingly relying on Internet searches and social networking websites to uncover detailed and private information about job applicants. Such Internet screening techniques have the potential to provide additional information beyond that found using traditional screening approaches. However, questions regarding the legality and appropriateness of this practice, as well as issues regarding the standardization, reliability, and validity of the information obtained, need to be addressed. The current work describes these issues associated with Internet screening and provides recommendations to help ensure this practice is used appropriately in organizations. Suggestions for future research on Internet screening are also discussed.     

LGBT Neighbourhoods and ‘New Mobilities’: Towards Understanding Transformations in Sexual and Gendered Urban Landscapes

In this article we apply insights from ‘new mobilities’ approaches to understand the shifting sexual and gendered landscapes of major cities in the global North. The empirical context is the purported ‘demise’ of traditional gay villages in Toronto, Canada and Sydney, Australia, and the emergence of ‘LGBT neighbourhoods’ elsewhere in the inner city. We reinterpret the historical geography of twentieth century LGBT lives and the associated ‘rise and fall’ of gay enclaves through the lens of the ‘politics of mobility’. In this reading, it is apparent that multifaceted movements — migration, physical and social mobility, and motility — underpin the formation of gay enclaves and recent transformations in sexual and gendered landscapes. After the second world war, LGBT communities in the global North were embedded in specific historical geographies of mobility and we trace these in the Canadian and Australian contexts. The ‘great gay migration’ from the 1960s to the 1980s has been joined by new LGBT constellations of mobility in the 2000s, and these have imprinted upon the sexual and gendered landscapes of Toronto and Sydney.     

Memberships Levels in U. S. Private Clubs During the 2008–2010 Economic Downturn

This study measured membership changes in private clubs in the United States during the economic downturn from 2008 to 2010. Specifically examined were the changes clubs experienced with their number of members, waiting lists, and attrition rates. A letter was sent via e-mail to the same 1,000 private clubs that were sent a survey in a similar study conducted by Ferreira and Gustafson (2006 Ferreira, R. R. and Gustafson, C. M. 2006. Declining memberships during an economic downturn in U.S. private clubs. International Journal of Hospitality & Tourism Administration, 7(2/3): 3–18. [Taylor & Francis Online] , [Google Scholar]) The managers of these clubs were members of the Club Managers Association of America. The majority of respondents managed country clubs and member-owned clubs, representing different areas of the United States. An overall response rate of 53% was achieved. Most clubs experienced a decrease in the overall number of members and an increase in annual attrition rate. Fewer clubs reported having a waiting list of members wanting to join. The clubs without waiting lists reported a larger number of membership openings in their clubs. The results of this study suggest the levels of memberships in many private clubs are heavily influenced by economic conditions. An implication from this study is that clubs need to implement membership development strategies during economic downturns because of the decline in the number of members, candidates proposed, and waiting lists during these periods.     

Hotel career management in China: Developing a measurement scale

This study aims to develop a measurement scale for organizational career management (OCM) in China's hotel industry. The scale development procedure includes four steps: developing initial items, implementing purifying measures, data collection, and assessing the reliability and validity of the proposed measurement scale. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are used to test the reliability and validity of the measurement scale thus developed. The development process results in a reliable and valid scale for hotel career management incorporating three dimensions: (1) career appraisal and advice, (2) a career development program, and (3) career training. Given the scarcity of research on career management in China, the measurement scale developed in this study will serve as a foundation for future research. The findings of this study may help to stimulate further empirical research on the relationship between hotel career management and employees’ career commitment and career satisfaction.     

Hotel school alumni’s intentions to use communication channels – a cross-generational comparison study

ABSTRACT

Alumni communication is vital in sustaining the relationship between alumni and their alma maters. This research investigated four cohorts of alumni, and their intentions to use a range of traditional and digital communication channels, including social media. An online questionnaire was sent to 8060 alumni and resulted in 595 usable responses, yielding a 7% response rate. The research results showed that alumni have the highest intentions to use the alumni e-newsletter and the alumni Website and the lowest intentions to use social media, e.g., Twitter, Instagram, and YouTube. Among alumni cohorts, significant statistical differences in their intentions to use these communication channels were identified. Given our findings, alumni communication staff are encouraged to leverage different communication channels targeting alumni in different age groups.     

The Health Consequences of Adverse Labor Market Events: Evidence from Panel Data

This study investigates the associations between self‐assessed adverse labor market events (experiencing problems with coworkers, employment changes, financial strain) and health. Longitudinal data are obtained from the National Epidemiological Survey of Alcohol and Related Conditions. Our findings suggest problems with coworkers, employment changes, and financial strain are associated, respectively, with a 3.1 percent (3.3 percent), 0.9 percent (0.2 percent), and 4.5 percent (5.1 percent) reduction in mental health among men (women). Associations are smaller in magnitude and less significant for physical health.     

How are Scope and Adding up Relevant for Benefits Transfer?

In this paper, we explore ways in which the theoretical constructs of scope and adding up can inform and improve the practice of benefit transfer. Specifically, we examine how the stated preference literature on scope and adding up can inform three critical steps in benefits transfer: study site selection, including studies to select for use in a meta-regression; calibrating benefit functions; and assessing transfer validity.
