We study the effects of traditional cigarette and e-cigarette taxes on use of these products among adults in the United States. Data are drawn from the Behavioral Risk Factor Surveillance System and National Health Interview Survey over the period 2011 to 2018. Using two-way fixed effects models, we find evidence that higher traditional cigarette tax rates reduce adult traditional cigarette use and increase adult e-cigarette use. Similarly, we find that higher e-cigarette tax rates increase traditional cigarette use and reduce e-cigarette use. Cross-tax effects imply that the products are economic substitutes. Our results suggest that a proposed national e-cigarette tax of $1.65 per milliliter of vaping liquid would raise the proportion of adults who smoke cigarettes daily by approximately 1 percentage point, translating to 2.5 million extra adult daily smokers compared to the counterfactual of not having the tax.

In recent years, the subject of transactional sex among young Dutch people has generated a heated social debate in the Netherlands. However, accurate data on this phenomenon are scarce. This article describes the findings of a qualitative study on young Dutch people's experiences of having sex in return for money or a material reward. Thirty in-depth interviews were conducted with young Dutch men and women aged 14 to 24. Participants came from diverse backgrounds in terms of gender, ethnicity, sexual orientation, and socioeconomic status. Experiences of trading sex differed in terms of the motivation to trade sex, the presence or absence of coercion, and the availability of other options for earning money. Participants' feelings about their experiences varied. For most participants, the sex itself was unpleasant and required considerable emotion management. Still, some felt adequately compensated by the reward or felt trading sex was preferable to other jobs. Gender played an important role, with feelings of disgust or shame reported especially by female participants, whereas male participants reported more positive experiences. Interactions involving coercion or financial dependence on trading sex generally had a negative emotional impact. Participants stressed the differences between their own experiences and professional prostitution.  相似文献

Frank Parsons (1909) founded the vocational guidance movement more than 100 years ago within the context of a shift from an agricultural to an industrial workplace. Today, globalization, workforce diversity, and the financial instability related to the Great Recession present numerous challenges to workers across the economic spectrum. In addition to highlighting Parsons's continued influence on career counseling practice, the authors draw on David Blustein's (2006) psychology of working to enhance the understanding of the needs of dislocated workers. Using case examples, the authors demonstrate how to incorporate insights from the psychology of working to address social justice, financial, relational, and self‐determination concerns among this vulnerable population. Counseling strategies for clients in transition, especially those considering educational options, are provided.  相似文献

This pilot study examined the feasibility and potential efficacy of a self-management program for seniors with chronic back pain and assessed for possible race/ethnicity differences in program impact. Sixty-nine seniors (24 African Americans, 25 Hispanics, and 20 non-Hispanic Whites) enrolled in the 8-wk community-based program. Efficacy outcomes included pain-related disability as measured by the Roland Morris Disability Questionnaire (RMDQ), pain intensity, pain self-efficacy, depressive symptoms, social activity, and functional status. Eighty percent of enrollees completed the program. Clinically important decreases in RMDQ scores were found for non-Hispanic White (adjusted change score = -3.53), African American (-3.89), and Hispanic (-8.45) participants. Improvements in all other outcomes were observed, but only for Hispanic participants. Results confirm that implementation of the protocol in urban senior centers is feasible, and the program shows potential efficacy. The race/ethnicity differences observed in the current study merit further investigation.  相似文献

Migration is the principal demographic process shaping patterns of human settlement, and it serves an essential role in human development. While progress has been made in measuring international migration, internal migration statistics are as yet poorly developed in many countries. This article draws on a repository of data established under the IMAGE (Internal Migration Around the GlobE) project to address this deficit by constructing the first comprehensive league table of internal migration intensities for countries around the world. We review previous work, outline the major impediments to making reliable comparisons, and set out a methodology that combines a novel estimation procedure with a flexible spatial aggregation facility. We present the results in the form of league tables of aggregate crude migration intensities that capture all changes of address over one‐year or five‐year intervals for 96 countries, representing four‐fifths of the global population. Explanation for the observed differences has been sought, inter alia, in historical, structural, cultural, and economic forces. We examine the links between development and migration intensity through simple correlations using a range of demographic, economic, and social variables. Results reveal clear associations between internal migration intensities and selected indicators of national development.  相似文献

A qualitative study among 22 young adults (20–25 years old) whose parents divorced during their childhood was conducted in Israel, using semi-structured, in-depth, open-ended interviews. Qualitative data analysis led to identification of three profiles, aiming at a grounded theoretical conceptualization. Three core themes were identified: the centrality of the family; short- and long-term implications of parental divorce and its relations to supportive coping resources; and perspective at young adulthood. Further analysis led to typifying participants by three profiles, which represent the grounded theoretical conceptualizations: resilience, survival, and vulnerability. The most prominent difference among the profiles was the relationships between participants and their parents, and their perception of ongoing parental responsibility. A thorough discussion of the results and their implications for future research, theory development, and practice are presented.  相似文献

Retrospective questions on educational attainment in national surveys and censuses tend to over-estimate high school graduation rates by 15-20% points relative to administrative records. Administrative data on educational enrollment are, however, only available at the aggregate level (state, school district, and school levels) and the recording of inter-school transfers are generally incomplete. With access to linked individual-level administrative records from a very large “West Coast metropolitan school district” we track patterns of high school attrition and on-time high school graduation of individual students. Even with adjustments for the omission of out-of-district transfers (estimates of omission are presented), the results of this study show that failure in high school, as indexed by retention and attrition, are almost as common as on-time high school graduation. In addition to the usual risk factors of disadvantaged background, we find that the “9th grade shock”—an unpredicted decline in academic performance upon entering high school—is a key mechanism behind the continuing crisis of high school attrition.  相似文献

Behavioral and electrophysiological indices of memory were examined in 12‐month‐old typically developing control infants (CON) and infants with history of perinatal hypoxic‐ischemic injury (HII) across 2 days. Using a visual paired comparison (VPC) procedure, novelty preference was tested immediately after a familiarization period and then after delays of 2 min and 24 h. Both groups showed a significant novelty preference only for the no‐delay condition. On day two, event‐related potentials (ERPs) were recorded while infants viewed the VPC familiar face, a more recently familiarized face, and a novel face, and mean amplitude for components thought to reflect memory (positive slow wave, PSW) and attention (negative central, Nc) were computed. In temporal regions, HII showed a diminished Nc and enhanced PSW to the recently familiarized face, while CON showed a similar trend for the PSW only. Overall, infants showed the largest PSW over left scalp regions. Finally, a positive correlation between VPC novelty preference after 24 h and PSW was found in CON, and preliminary results suggest that this association differs as a function of group. Therefore, in comparison with CON, HII showed both similarities and differences on individual tasks of memory as well as potentially disparate relations between the behavioral and neural mechanisms underlying memory performance.  相似文献
