State lottery revenues are shown to increase during the week transfer payments are distributed. The timing of the increase in lottery purchases suggests a portion of the transfer payments is used to purchase lottery tickets. In addition to providing information on the timing of lottery purchases, this study finds sales of Pick 3 and Pick 4 tickets increase during the period, while sales of Pick 5 and Pick 6 games do not, suggesting a general preference for the relatively higher probability, smaller jackpot games for the group.

In the nonparametric measurement of allocative efficiency, output prices are fixed. If prices are endogenous, the overall output in the market determines the allocative efficient point. We develop an alternative semi-nonparametric model that allows prices to be endogenously determined.  相似文献

Statistical Thinking in Empirical Enquiry   总被引:4,自引:0,他引:4  
This paper discusses the thought processes involved in statistical problem solving in the broad sense from problem formulation to conclusions. It draws on the literature and in-depth interviews with statistics students and practising statisticians aimed at uncovering their statistical reasoning processes. From these interviews, a four-dimensional framework has been identified for statistical thinking in empirical enquiry. It includes an investigative cycle, an interrogative cycle, types of thinking and dispositions. We have begun to characterise these processes through models that can be used as a basis for thinking tools or frameworks for the enhancement of problem-solving. Tools of this form would complement the mathematical models used in analysis and address areas of the process of statistical investigation that the mathematical models do not, particularly areas requiring the synthesis of problem-contextual and statistical understanding. The central element of published definitions of statistical thinking is "variation". We further discuss the role of variation in the statistical conception of real-world problems, including the search for causes.  相似文献

ABSTRACT

Based on the theoretical foundation of emotion regulation, this exploratory study aimed to examine changes in tourists’ perceived well-being and to determine whether these changes were due to use of emotion regulation strategies (ERSs) during their vacation. This study used travel diaries to record tourists’ use of ERSs on a daily basis, and also measured tourists’ perceived well-being one day before and after their vacation. Results indicated that tourists had significantly higher perceptions of well-being after vacation, and those who used ERSs were more likely to indicate a higher sense of well-being after vacation. The results provide new insight into which aspects of tourists’ subjective and psychological well-being can be boosted by taking vacations and how these aspects may be enhanced by using different ERSs.  相似文献

Within the professional kitchen bullying is reported as widespread, aggressive and related to a significant retention problem. This research explores negative behaviour in professional kitchens and its impact on organisational commitment. A mixed methods approach is used employing a survey among chefs followed by semi-structured interviews. An exploratory factor analysis examines the underlying constructs of bullying and job satisfaction and data are analysed through Partial Least Squares. Our research highlights that bullying behaviour is experienced most by younger, more junior chefs. However verbal bullying, the form most strongly reported, has no effect on either satisfaction or commitment. Emergent themes of communication and inclusion illustrate bullying behaviour to be a cohesive aspect of kitchen culture. Our findings suggest behavioural impacts, rather than bullying characteristics, must be considered within their context in order to establish whether or not they are actually damaging to an industry.  相似文献

Surveys of beach visitor motivation in Ireland, Wales, Turkey and the USA indicate that beach awards play an insignificant role in motivation to visit beaches. However, a number of criteria closely identified with awards, notably cleanliness and water quality, are revealed to be very important. Aesthetic and emotional factors such as scenic setting and general ambience, and practical concerns such as proximity and range of activities available are much more important than beach awards in attracting visitors to beaches. The merits of beach awards are critically reviewed and it is concluded that any benefits that might accrue are in areas other than attracting visitors.  相似文献

Using a difference-in-differences estimation framework and state-level data, we investigate the potential role of HIV/AIDS in contributing to declining abortion utilization in the United States. Our results suggest that the perceived risk of HIV contraction negatively affected unwanted pregnancies. Specifically, a 10% increase in HIV incidence is associated with 0.34–1.1% fewer abortions per live births, an effect that can account for at least one-tenth of the sharp decline in abortions observed from the early 1980s to mid-1990s.  相似文献

The charitable giving of a large sample of publicly quoted UKfirms is analysed within a model that explores the profit maximisationand managerial utility enhancement motives for giving. The empiricalmethod draws a distinction between the decision to participatein giving and the determination of the amount of corporate contributions.Firm size and advertising intensity are found to be positivelyassociated with the probability of participation in giving.Stricter corporate governance and the rate of directors' remunerationare negatively related to the probability of participation.Among givers, the rate of giving is related positively to R&Dintensity, the rate of directors' remuneration, and corporateprofitability and negatively to firm indebtedness.  相似文献
