We examine how soda sales changed due to the campaign attention and election outcome of a local excise tax on sugar‐sweetened beverages. Using panel data of beverage sales from university retailers in Berkeley, California, we estimate that soda purchases relative to control beverages significantly dropped immediately after the election, months before the tax was implemented in the city of Berkeley or on campus. Supplemental scanner data from off‐campus retailers reveal this result is not unique to the university setting. Our findings suggest soda tax media coverage and election outcomes can have larger effects on purchasing behavior than the tax itself. (JEL D12, H20, C23, I38, Q18) 相似文献

A well-known procedure for the optimization of a second-degree response function over a spherical region of interest is that of ridge analysis. Khuri and Myers (1979) introduced a modification of this procedure by incorporating a certain constraint on the prediction variance. Both procedures, however, assume that the response variable has a constant variance throughtout the experimental region. In the present article, we consider two extensions to Khuri and Myers modifioed ridge analysis. The first extension relaxes the constant variance assumption. In the second extension. generalised linear models are used instead of the trasitional linear model. which are commenly used in responce variables that are not necessaily continusly distribution, including these have discreate distributions, Two examples are presented to illustrate the implementation of the proposed extensions. 相似文献

ABSTRACTThe efficiency of interventions in addiction is associated with the processes of practitioners’ professional development. Identity formation is studied extensively for clinical professions but little research focuses on social workers working in addiction settings. This study examined the experience of social workers working in a community treatment network in Greece. Fifteen interviews were conducted with 11 women and 4 men, ranging between 29 and 47 years οf age, who worked in different centers within the network. Data were analyzed following the guidelines of Interpretative Phenomenological Analysis, offering in-depth examinations of people’s lived experience. The results delineate a series of transformations in professional identity comprising a process of biographization. The participants highlighted intrapersonal and relational factors that influence this process which leads to self-understanding and engagement with the therapeutic community. The results contribute to deciphering the factors that influence social workers’ experience in their professional identity formation in substance abuse treatment contexts. 相似文献

In 2011, Portugal launched a residence permit programme to attract foreign investment from non-EU citizens, with Chinese business migrants representing those taking most advantage of this initiative. This paper analyses this policy measure and assesses its social consequences, as a new way that Chinese migrants have to enter Portugal. Firstly, we characterise this programme by identifying its principles and legal requirements, using official data from 2012 to 2018. We then describe the emergence of this type of residence permit as a response to the financial crisis of 2011, and as part of a neoliberal political rationality that has guided a governance model since this time. Next, we characterise the profile of Chinese citizens who benefit from this initiative and claim residence permits on the basis of their economic power. Finally, we discuss the social and political implications of this kind of entrance to Portugal, to provide some insights for policymakers. 相似文献

This article presents two major surveys, carried out in Portugal, on the inclusion of families and individuals in social networks of support and affinity. The first, dating from 1999, sought comprehensively to reconstruct families' social networks by mapping effective support relations. The second survey, fielded in 2009–10, followed a family configuration perspective which sought to reconstruct individuals' networks of close relationships, and the issue of informal support only arose as providing further insight into the characteristics of personal networks. Both surveys will be analysed from a comparative perspective which, while stressing their different but connected conceptual orientations, compares each one's methodological strategies and operationalization procedures. Finally, the main results of each survey are outlined, leading to a brief discussion of the ways in which the two surveys complement each other. 相似文献

This paper analyzes whether schooling increases intelligence measured by intelligence quotient (IQ). We use a longitudinal dataset where the individuals have conducted IQ tests both at ages 10 and 20. We estimate the effect of schooling on IQ at age 20 conditional on IQ at age 10 and other measures of early cognitive ability to account for selection into noncompulsory schooling. Ordinary least squares estimates indicate that 1 year of schooling increases IQ by 2.9–3.5 points (about 0.2 SD deviations), and instrumental variables estimates are similar. 相似文献

This article starts with a brief overview of the role of women in the workforce in the former USSR and contemporary Russia. Next, gender stereotypes in the human capital development practices of Russian companies are described. The article then presents the results of a study of the gender aspects of human capital practices (including hiring, evaluation, training and development, and promotion policies) in 60 Russian companies from nine sectors of the economy. It then reflects on some of the main features of gender issues related to human capital development in Russia. Most are determined by socio-cultural and psychological barriers in the social (public) and individual consciousness of managers and employees. 相似文献

Abstract. This paper uses a representative sample of the Russian Federation, the Russian Longitudinal Monitoring Survey, to estimate the returns to education in this ex‐communist country. We tackle this classic issue in labor economics with the realistic expectation of obtaining results for Russia comparable in quality and reliability to those available in developed countries and other economies in transition. Using standard regression techniques we find that the returns to education in Russia are quite low compared with those reported in the literature on countries throughout the world, in almost no specification reaching higher than 5 per cent. Moreover, there is virtually no improvement in returns to education in the 1992–99 period, a result somewhat at odds with other studies using Russian data from similar time periods. When we instrument our main regressor using policy experiments from the 1960s, we find comparable results. We also perform a selectivity correction and discover even lower returns to education for men, although they become slightly higher for women. Additionally, we find extremely low returns to tenure, which can even become negative in certain specifications. 相似文献

We examine birth order effects on academic achievement for ten-year-old students using data for the entire population of fifth graders in Norway 2007/2008. The analysis thus adds to a thin empirical literature focusing on birth order effects among young children. We find that being firstborn confers a significant advantage in families with two, three and four children. The analysis makes two other contributions. First, we provide evidence that unless mother's age at childbirth is included among the control variables, only small and imprecise birth order effects are revealed in families with low socioeconomic status. Second, we provide some evidence that the birth order effects differ across families with highly educated and less educated mothers, which lend support to the resource dilution model over the confluence model. 相似文献

The present article is based on a small-scale research that took place with third-year students in the department of social work at Technological Educational Institute of Patras. During class the students, who undertake the laboratory course ‘Social Work with Families’, were asked to discuss family roles and depict them on drawings. Analysing their drawings in a qualitative approach the findings suggest that students adopt traditional views on family issues and the family roles. Various gender stereotypes and prejudices were reflected in students' drawings and this is alarming for both social work education and practice. 相似文献
