Although many studies find that smoking bans reduce cigarette demand, arguments can be made for smoking bans also affecting alcohol demand. Accordingly, in this paper we address the determinants of state-level alcohol demand, which we treat as a function of various economic and demographic variables, as well as smoking bans. Results reveal that smoking bans reduce the demand for beer and spirits. Furthermore, smoking bans tend to intensify the complementary relationship between cigarettes and alcohol, which suggests that smoking bans have altered consumer demographics in the alcohol market. We also find the nature of the smoking ban matters, as bans specific to restaurants and bars lead to larger reductions in beer and spirits consumption, but increase the demand for wine. 相似文献

Previously reported observed data on risky everyday driving are brought together and reanalyzed in order to focus on the relation between risky driving and the size of the car being driven, as indicated by car mass. The measures of risky driving include separation between vehicles in heavy freeway traffic and speed on a two lane road. Observed seat belt use provides a third measure of driver risk. Confounding effects arising from the observed association between car mass and driver age are taken into account by segmenting the data into three driver age groups. Driver risk taking is found to increase with increasing car mass for each of these three aspects of everyday driving. The implications of these results with respect to driver fatality rates are discussed in terms of a simple model relating observed risky driving to the likelihood of involvement in a severe crash. 相似文献

Non-profit industrial development organisations (NIDOs) represent a common but little studied community response to widespread
deindustrialisation in the United States. These non-profits are organised as chartered not-for-profit corporations, public
authorities or agencies of local government. Most receive at least some public funding to promote local industrial development.
Thus, a key issue is how accountable NIDOs are to the public they have been created to serve. Data from national surveys of
NIDO executive directors in 1984 and 1994, as well as a survey of six case study boards of directors, suggest that public
accountability is an increasingly important concern among NIDOs. Public hearings, efforts to diversify the boards in terms
of gender and race, and connections to community development corporations and other local organisations are among the ways
NIDOs attempt to be accountable to the general public. Although few women or racial minorities serve on NIDO boards, those
boards with representation of these groups tend to be more concerned with public accountability. Boards containing public
officials tend to be less concerned, presumably because their presence makes the NIDOs more directly accountable as a result
of the participation of elected public representatives. 相似文献

Using a sample consisting of 4,997 married couples from the National Survey of Families and Households, individual emotional
distress, the occurrence of couple disagreements, couple fighting, and couple quality time together mediated the relationship
between financial strain and personal assessments of marital instability. The overall results suggest that financial strain
influences both positive and negative forms of couple interaction which are stronger mediators than personal emotional distress
of the relationship between financial strain and marital instability. The results further suggest that there were no gender
differences among these linkages. 相似文献

The value of listening and talking to young people with experience of the care system has been recognised as a vital and positive contribution to social work students' learning. A model of co-production was used to develop a series of speed mentoring events whereby social work students placed in local authority children and family settings were mentored by young people with experience of the care system. This tentative review of this small-scale project shares the authors' critical reflections on the value and reliability of this model, for evaluating the outcomes of co-productive mentoring relationships between young people and social work students. The reversal of the power dynamic between student and service user contributed to the unsettling of assumptions about each other and empathy for each other's role. The student authors reflect on learning about the child's experience that has influenced their practice. The mentor authors welcomed the opportunity to participate in the development of ‘young people friendly’ social workers. Suggestions are made as to how this model could be developed to contribute to a more systematic approach to the role of service users in mentoring, advising and contributing to the supervision process of students and social workers. 相似文献

The benefits of adjusting for baseline covariates are not as straightforward with repeated binary responses as with continuous response variables. Therefore, in this study, we compared different methods for analyzing repeated binary data through simulations when the outcome at the study endpoint is of interest. Methods compared included chi‐square, Fisher's exact test, covariate adjusted/unadjusted logistic regression (Adj.logit/Unadj.logit), covariate adjusted/unadjusted generalized estimating equations (Adj.GEE/Unadj.GEE), covariate adjusted/unadjusted generalized linear mixed model (Adj.GLMM/Unadj.GLMM). All these methods preserved the type I error close to the nominal level. Covariate adjusted methods improved power compared with the unadjusted methods because of the increased treatment effect estimates, especially when the correlation between the baseline and outcome was strong, even though there was an apparent increase in standard errors. Results of the Chi‐squared test were identical to those for the unadjusted logistic regression. Fisher's exact test was the most conservative test regarding the type I error rate and also with the lowest power. Without missing data, there was no gain in using a repeated measures approach over a simple logistic regression at the final time point. Analysis of results from five phase III diabetes trials of the same compound was consistent with the simulation findings. Therefore, covariate adjusted analysis is recommended for repeated binary data when the study endpoint is of interest. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Outsourcing is becoming an increasingly prevalent phenomenon not only in business life, but also in the affairs of governments and in the lives of individuals and families. But what exactly is outsourcing and what are its consequences? I will argue that outsourcing offers entities a set of freedoms (i.e., possibilities of action and non‐action) that are not considered possible in this practice’s absence. However, many of these freedoms are precarious in that they involve a multitude of risks and dangers both for those outsourcing their affairs and for those who take them on. Although there are multiple freedoms of this sort, one is focused upon here; how outsourcing allows entities to contract, in the sense of limiting, their responsibilities. Three specific ways in which outsourcing allows entities to do this are detailed. Recognizing this precarious aspect of the freedoms associated with outsourcing is important because it highlights the social risks involved in this practice. 相似文献

Women have had a long history of participating in terrorist activity. This history extends from the earliest modern terrorist group, from the nineteenth century Russian People’s Will to the current wave of suicide bombings carried out by the Chechen Black Widows and the Tamil Tiger’s Birds of Paradise. This article traces the history of female involvement in modern terrorism and then goes on to make a number of generalizations about this experience. Among other things, the writers point out that women have played strong leadership roles in left-wing, revolutionary bands, while these roles have been far fewer with right-wing and racist aggregations. Women have tended to be late-comers to contemporary, religiously-inspired terrorism: Muslim religious authorities first had to endorse their participation. 相似文献
