In the context of claims that the European Aviation Safety Agency’s flight and duty- time regulations pose a threat to safety, pilot workload and fatigue were assessed on two short-haul routes using a mixed-methods approach. Data produced by the US Air Force School of Aerospace Medicine Crew Status Survey (CSS) showed that pilots rarely assessed workload and fatigue to be high-risk. Data produced by an ethnographic study somewhat contradicted the CSS findings, with some pilots claiming to be fatigued. The combined data suggested a correlation between both workload and fatigue and aviation system dynamics such as airspace manoeuvring restrictions, especially in the vicinity of busy airports. The research presented an opportunity to test claims made for the CSS, specifically that it is ‘easily understood, easy to administer and minimally intrusive’. Missing forms and errors suggest that it is not as reliable a research instrument as proponents suggest, although contextual factors may have served to reduce the volume and quality of data. It is concluded that a pre-survey, systems-thinking-informed evaluation of the host airline would suggest ways of improving buy-in. 相似文献

The relocation of the wool market from London to the major Australian port cities from the late nineteenth century required the formation of an institution to govern the auction business, namely the wool brokers' association. Regional variations, among Sydney, Melbourne, and Brisbane, occurred in the structure and effectiveness of the institution despite each regional association having been formed around the same time, for the same purpose, and with an overlap of participating firms. We draw on institution theory to guide our account and find that the impact of legacy factors and differences in market conditions explain the regional variations. 相似文献

In the year to August 2002, 15% of the New Zealand road toll was attributed to 15–19 year-old drivers. This is the highest percent of casualties by any five-year age group, with the motor vehicle accident risk peaking at 16 years of age. New Zealand has the highest road accident statistic for this age group in the motorised world. It has been proposed that the driver licensing age be raised from 15 to 17 years of age. A 1998 Parliamentary Select Committee rejected the final proposal of a minimum driver licensing age of 16, on the grounds that such a rise would disadvantage rural youth through less accessible employment, educational facilities, social, and recreational activity, due to inadequate transport alternatives. This paper presents the results of research that examined the impact of the minimum driver licensing age on youth mobility. High school students were surveyed through interviews, questionnaires and travel diaries. It was concluded that the social benefits of raising the minimum driver licensing age to 17 years of age outweighed the social benefits of the status quo, as only minimal number of essential trips were totally dependent on youth acquisition of a driver licence. 相似文献

The purpose of this study is to investigate the structural relationships among intellectual capital (INCAP) dimensions and business performance (BUPER) in upper‐upscale hotels. This study classified INCAP into three dimensions: human capital (HUCAP), organizational capital (ORCAP) and customer capital (CUCAP). This study applied a structural equation modeling to investigate the proposed model and hypotheses. The results showed that HUCAP affects ORCAP and CUCAP and that ORCAP influences CUCAP. INCAP dimensions, with the exception of HUCAP, directly affect BUPER; however, HUCAP indirectly affects BUPER via ORCAP and CUCAP. This study helps upper‐upscale hotel managers identify relevant INCAP dimensions and their indicators to enhance BUPER. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The objective of this study was to measure the immediate impacts of a film on the perceptions of viewers from different countries. The film chosen for this experiment was the Motorcycle Diaries in which South America was featured prominently in the film. Using established scales from the tourism and marketing literature, viewers from the USA, Canada and Spain were surveyed before and after seeing the film, and results showed that the film did change the viewers' perceptions of South America. After watching the film, a large percentage of the respondents expressed a desire to visit the countries seen in the film, with Canadians showing a significantly higher desire to visit South America than the US and Spanish participants. Those who were motivated to travel by the film were especially influenced by the scenery, landscape and the cultural attractions of the destination as depicted in the movie.

Previous studies have suggested that more liberal abortion laws should lead to a decrease in marriage rates among young women as ‘shotgun weddings’ are no longer necessary. Empirical evidence from the United States lends support to that hypothesis. This article presents an alternative theory of abortion access and marriage based on the cost of search which suggests that more liberal abortion laws may actually promote young marriage. An empirical examination of marriage data from Eastern Europe shows that countries that liberalized their abortion laws saw an increase in marriage rates among nonteenage women. 相似文献

This paper analyses the potential changes in the operational structure of deposit-taking financial institutions that securitize assets. Findings indicate that banks can create an asset securitization pipeline structure that enables them to increase their return on capital. In other words, through securitization banks can expand their loan provision business without increasing their liabilities or their capital levels. Using a contingent claims model, four factors that impact on the bank's decision to securitize are highlighted and analysed: (i) the level of deposit insurance; (ii) capital adequacy requirements; (iii) insolvency risk; and, (iv) the risk of credit enhancements. Furthermore, we identify key accounting and regulatory challenges that emerge for banks from the process of asset backed securitization. 相似文献

The limit order book of an exchange represents an information store of market participants’ future aims and for many traders the information held in this store is of interest. However, information loss occurs between orders being entered into the exchange and limit order book data being sent out. We present an online algorithm which carries out Bayesian inference to replace information lost at the level of the exchange server and apply our proof of concept algorithm to real historical data from some of the world’s most liquid futures contracts as traded on CME GLOBEX, EUREX and NYSE Liffe exchanges. 相似文献

Technological advances impact a firm’s investment decision, as they affect the investment cost. They can also affect the profitability due to demand shocks. We study a firm’s optimal investment decision when technological advances occur as surprises and induce uncertain reductions in the investment cost and in earnings. Despite this complex setting we derive closed-form solutions for the investment option value and the investment threshold. When technological advances only impact the investment cost, we demonstrate significant contributions compared to existing research, which restricts the analysis by keeping the expected investment cost path constant. For example, we show that, albeit the investment threshold is constant, the option value is very sensitive in the expected impact of technological advances. Leaving the restrictive setting, we obtain more intuitive results, e.g. that more frequent technological advances increase the option value. When technological advances impact future earnings we find important long-term effects: the investment threshold increases, whereas the option value decreases. Finally, earnings volatility postpones investment, while uncertainty due to technological advances expedites investment. 相似文献

Youth expeditions are associated with a range of benefits for participants. More young people are participating in overseas expeditions than ever before as vacation and gap year choices are diversified by a rising number of expedition providers. To date, there has been no systematic research effort to draw together and evaluate the evidence that underpins the benefits or, otherwise, for youths participating in overseas expeditions. This paper reviews empirical and philosophical literature which has been published in a range of journals and themes emerging are placed into a personal growth model. This review (or mapping exercise) focused on post-1990 literature and found 35 key publications which met the criteria: youth expedition; duration exceeding 14 days, self-propelled, and based overseas or out-of-state. The 35 publications (UK 26; USA 4; Australia 3; Japan 1; South Africa 1) were subjected to a thematic analysis using Greenaway’s ‘Four Arrows’ model of personal growth. Outcomes associated with overseas youth expedition participation included (1) upward personal growth (realising potential) including increased confidence; physical and social resilience; self-reliance and ability to overcome challenges, (2) outward personal growth (learning about & relating to others), (3) inward personal growth (learning about self) and (4) downward personal growth (learning about environment). The processes that were valued in overseas expeditions and which, with some caution, may be linked with some of the aforementioned outcomes include: genuine independence; group isolation and self-sufficiency; person-centred leadership; positive responses to stress and physically demanding activity. Suggestions for areas for further meaningful research are offered. 相似文献
