Abstract

This paper considers the advantages and disadvantages of cashless gambling technologies in the Australian gaming machine industry from supply and demand side perspectives. Exploratory interviews with key industry stakeholders formed the basis of the first stage of data collection, Analysis of these data led to the development of questionnaire items based on innovation models, which were administered to patrons (n =134) of two large gambling venues where card based gambling had recently become available. The supply side advantages of cashless technologies were strongly articulated, and include reduced venue overheads and operating costs. Regulators are primarily interested in the features that may encourage responsible gambling. All consumers acknowledge that the card is easy to use and convenient, although card and system reliability were strong concerns for non–users. These consumer disadvantages are offset where the venue and its management regime are positively perceived.  相似文献

Much effort in life-history theory has been addressed to the dependence of life-history traits on age, especially the phenomenon of senescence and its evolution. Although senescent declines in survival are well documented in humans and in domestic and laboratory animals, evidence for their occurrence and importance in wild animal species remains limited and equivocal. Several recent papers have suggested that methodological issues may contribute to this problem, and have encouraged investigators to improve sampling designs and to analyse their data using recently developed approaches to modelling of capture-mark-recapture data. Here we report on a three-year, two-site, mark-recapture study of known-aged common terns (Sterna hirundo) in the north-eastern USA. The study was nested within a long-term ecological study in which large numbers of chicks had been banded in each year for > 25 years. We used a range of models to test the hypothesis of an influence of age on survival probability. We also tested for a possible influence of sex on survival. The cross-sectional design of the study (one year's parameter estimates) avoided the possible confounding of effects of age and time. The study was conducted at a time when one of the study sites was being colonized and numbers were increasing rapidly. We detected two-way movements between the sites and estimated movement probabilities in the year for which they could be modelled. We also obtained limited data on emigration from our study area to more distant sites. We found no evidence that survival depended on either sex or age, except that survival was lower among the youngest birds (ages 2-3 years). Despite the large number of birds included in the study (1599 known-aged birds, 2367 total), confidence limits on estimates of survival probability were wide, especially for the oldest age-classes, so that a slight decline in survival late in life could not have been detected. In addition, the cross-sectional design of this study meant that a decline in survival probability within individuals (actuarial senescence) could have been masked by heterogeneity in survival probability among individuals (mortality selection). This emphasizes the need for the development of modelling tools permitting separation of these two phenomena, valid under field conditions in which the recapture probabilities are less than one.  相似文献

The Polls Trends: Twenty Years of Public Opinion about Global Warming   总被引:2,自引:0,他引:2  
Over the past 20 years, there have been dozens of news organization,academic, and nonpartisan public opinion surveys on global warming,yet there exists no authoritative summary of their collectivefindings. In this article, we provide a systematic review oftrends in public opinion about global warming. We sifted throughhundreds of polling questions culled from more than 70 surveysadministered over the past 20 years. In compiling the availabletrends, we summarize public opinion across several key dimensionsincluding (a) public awareness of the issue of global warming;(b) public understanding of the causes of global warming andthe specifics of the policy debate; (c) public perceptions ofthe certainty of the science and the level of agreement amongexperts; (d) public concern about the impacts of global warming;(e) public support for policy action in light of potential economiccosts; and (f) public support for the Kyoto climate treaty.  相似文献
