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

Female adolescents who have experienced violence often struggle to maintain a sense of agency and control over their own bodies—bodies that have been objectified through direct physical assault. In order to understand more fully the impact of direct violence on the meaning of the body for female adolescents, the author discusses normative aspects of the meaning of the body and their relationship to the developmental processes of individuation and connectedness as well as subjectivity and objectivity. Case vignettes are used to explore the intersection of violence and the meaning and use of the body for female adolescents. Implications for intervention are proposed. 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 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

Springer and Hauser (An Assessment of the Construct Validity of Ryff’s Scales of Psychological Well-Being: Method, Mode, and Measurement Effects. 2006. Social Science Research 35) tested one key aspect of the validity of Ryff’s six-factor model of psychological well-being (RPWB), namely, whether there is substantial independent variation among the six factors. In several large and heterogeneous samples, under a variety of model specifications, and using various sets of RPWB items, we found very high factor correlations among the dimensions of well-being, especially personal growth, purpose in life, self-acceptance, and environmental mastery. That is, the six-factor model makes theoretical claims that do not yield large or consistent empirical distinctions when standard measures and instrumentation are used. Where Ryff and Singer’s comment (Best News Yet on the Six-Factor Model of Well-Being. 2006. Social Science Research 35) refers directly to that analysis, their methodological discussion is most often irrelevant or incorrect. Their text largely ignores and fails to challenge our strong empirical findings about the factorial structure of well-being. In this response, we reinforce these findings and their implications for the (in)validity of the six-factor well-being model as implemented by Ryff. We also explain why Ryff and Singer’s lengthy review of studies that show differential relationships of RPWB factors with other variables should be interpreted with far greater caution than Ryff and Singer recognize. We offer recommendations for analyzing RPWB items in surveys that have already been conducted, but we also emphasize the need for a thorough rethinking of the measurement and dimensionality of psychological well-being. 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
