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

BackgroundHeideggerian hermeneutic phenomenology has been used widely to understand the meaning of lived experiences in health research. For midwifery scholars this approach enables deep understanding of women's and midwives’ lived experiences of specific phenomena. However, for beginning researchers this is not a methodology for the faint hearted. It requires a period of deep immersion to come to terms with at times impenetrable language and perplexing concepts.ObjectivesThis paper aims to assist midwives to untangle and examine some of the choices they face when they first come to terms with an understanding of this methodology and highlights the methodology's capacity to reveal midwifery authenticity and holistic practice.DiscussionThe illumination of a selection of various concepts underpinning hermeneutic phenomenology will inform midwives considering this methodology as suitable framework for exploring contemporary midwifery phenomena.  相似文献

The perceptual effects of varying levels of expert advice for potentially improving on strategic decisions were examined in conjunction with goals. The amounts of advice about decision alternatives, as well as assigned goals ranging from “nearly impossible” to “easy,” were manipulated. The task used was complex and functioned perceptually as an “ill-structured” problem. Mixed results indicated that more advice significantly affected satisfaction but advice in general had little influence on effort. On the other hand, as goal difficulty decreased, satisfaction and effort significantly increased. Easy goals were superior to more difficult ones within this perceptually ill-structured decision-making situation.  相似文献

This study assessed the knowledge and attitudes of young adults without children in regard to discipline and parenting practices. A qualitative design was utilized (n?=?26) with semistructured focus groups. Results indicated participants believed discipline is important, with spanking and loss of privileges being the most effective strategy for behavior change. The majority of participants reported plans to discipline future children the way in which they were disciplined, suggesting a high percentage intend to utilize spanking. Findings suggest that personal experiences shape parenting beliefs, attitudes, and knowledge. Results inform efforts at educating future parents on appropriate parenting practices and indicate the need for protocols for young adults to educate about practices that may diverge from their personal experiences.  相似文献

Abstract

Social justice is central to Australian social work. Principles of social justice underpin the definition of social work as a profession, its code of ethics, and its standards of practice and education. However, there is a dearth of empirical research regarding what social justice has meant to social work over time and how it has been enacted in practice, topical as social inequalities continue to escalate. As a first-stage study, this paper examines how social justice was represented within 19 Norma Parker Addresses delivered by Presidents of the Australian Association of Social Workers at national conferences between 1969 and 2008. Two key themes were evident: social justice as a concept and social justice as social work practice. Social justice was represented conceptually throughout the Addresses as an enduring guiding principle and moral responsibility for social work. How social justice was enacted in practice included themes of: standpoint; practices and strategies; educating social workers; and contested and constrained practice. The meanings and practices of social justice were embedded within the changing contexts within which the Addresses were delivered. Further historical studies can inform social work knowledge, practice, and critical reflection as the profession continues to evolve and confront persistent social justice challenges.  相似文献

Following previous work on inequality in health opportunity, this paper attempts to determine the contribution of circumstances, efforts and lifestyle, and demographic variables to the overall inequality in health in Luxembourg. Health is measured via the answers given to a question on self-assessed health and is considered as an ordinal variable. The educational level of each parent, the financial situation of the family during childhood, the area of birth of the individual, and of his/her parents, and the year of immigration are considered as circumstances. Effort and lifestyle variables are proxied by information on the educational level of the individual, whether he/she smoked and whether he/she had a physical activity on a regular basis. Sex and age are considered as demographic variables. To solve the issue of correlation between circumstances and effort and lifestyle the estimation is implemented in two stages. In the first stage, each effort and lifestyle variable is regressed in a separate equation against the vector of circumstances and demographic variables and, in a second stage, the individual health status is regressed against the vector of circumstances and demographic variables along with the estimated residuals of the effort equations described previously. The respective impacts of the three categories of explanatory variables (circumstances, effort and lifestyle and demographic variables) on health inequality are derived via a Shapley decomposition of the likelihood ratio of the health ordered logit regression. It appears that differences in circumstances and effort and lifestyle explain each around a quarter of this likelihood ratio.  相似文献
