This article aims to introduce and explain a guideline to plan and perform health campaigns through social marketing. The model is based on the social marketing principles and its objective is to help professionals develop an action plan setting step-by-step the processes to produce health campaigns to achieve the ultimate goal behavior change. Three levels of action 10 have been set: (i) diagnosing the social problem; (ii) designing the benefits of changing behavior; and (iii) setting the marketing mix. This social marketing plan is an option to introduce customer orientation backed by integrated marketing aimed at generating consumer satisfaction as the key to behavior change in the public health policies. 相似文献

Financial and political factors are widely considered to be an explanatory factor of the privatisation of public services. However, the empirical evidence in this respect is not convincing. This paper considers elements of long-term financial condition and ideological and political strength, together with other socio-economic factors and the effects of the current global financial crisis, to address the financial stress–privatisation relationship, with respect to urban water services, observed during the period 2002–2012 in Spanish municipalities. A discrete time survival model is applied, and the results obtained show that certain elements of financial condition, together with political and ideological factors, are decisive influences in decisions to privatise urban water services. We also highlight the major impact of the Great Recession and its effect on the financial stress–privatisation relationship. 相似文献

Organized activity participation provides important opportunities for adolescents to develop assets and resources related to positive youth development. Predisposing factors, in addition to sociodemographics and self-selection factors, may influence how youth participate over time. In this study, we used growth mixture modeling with longitudinal data from African American adolescents attending urban high schools in Flint, MI to identify subgroups of participation trajectories (Wave 1 N = 681, mean age at Wave 1 = 14.86 years, 51 % female). We measured activity participation using psychological and behavioral engagement across multiple contexts over the 4 years of high school. We examined how predisposing risk and promotive factors were related to these trajectories, accounting for sociodemographic and self-selection factors. The results indicated three participation trajectories: a low group decreasing over time (74 %), a moderate, consistent participation group (21 %) and a moderate, increasing group (5 %). More substance use was associated with lower odds of being in the moderate/consistent versus low/decreasing participation group. More parental support was associated with lower odds of being in the moderate/increasing versus the moderate/consistent group. Our results suggest that addressing predisposing factors such as substance use may help facilitate participation over time. 相似文献

ABSTRACTThis article takes at its starting point the idea that maternalism and entrepreneurialism are necessarily antithetical as Julie Stephens argues in Confronting Postmaternal Thinking: Feminism, Memory, and Care [2012. New York: Columbia University Press]. Building on scholarship which shows how motherhood has become commercialised and commodified in contemporary culture, we extend this field by investigating how mothers who are providers of services to other mothers and pregnant women are negotiating neoliberalism and entrepreneurialism. Through an empirical investigation of birth and parenting entrepreneurs – including hypnobirthing classes and placenta pill businesses – in Bristol, UK we argue that our self-employed participants were building community and care economies within neoliberal modes of self-production, thus suggesting a more complex and ambivalent relationship between entrepreneurialism and postmaternalism. We suggest that the experiences of women entrepreneurs or ‘mumpreneurs’ offer insights into how the spaces of work might be, counter to Stephens’ characterisation, places of negotiation and struggle for the politics of feminism, rather than sites of ‘anti-maternalism’ or the ‘forgetting’ of maternalism. Moreover, our participants’ accounts were strongly shaped by feminist ethics of care thus challenging the representation of such services as therapeutic postfeminist technologies of self-work. 相似文献

Positive school climates have been found to have favorable effects on adolescent health risk behaviors and mental health outcomes.
However, the mechanisms by which teacher behavior may promote such effects in high schools have not been extensively studied.
Based on social control theory and a social developmental-contextual model, it was predicted that by respecting students’
points of view and decision making capabilities, teachers can help build respectful school climates that encourage healthy
norms of behavior. Structural equation modeling with a nationally representative sample of 476 youth ages 14–18 supported
the model. Adolescents who reported higher teacher support and regard for student perspectives in their high schools were
more likely to see their schools as having respectful climates and healthy norms of drug use which was associated with lower
levels of personal drug use. Students in such schools also reported greater social belonging and fewer symptoms of depression.

The purpose of this paper is to empirically analyze the effects of political instability, social polarization and the quality of institutions on inflation volatility over time and across countries. Using the system-GMM estimator for linear dynamic panel data models on a sample covering 160 countries, analyzed in the period from 1960 to 1999, this paper finds that higher degrees of political instability and social polarization, less democracy, and lower de facto central bank independence are associated with more volatile inflation rates. Furthermore, political instability has greater effects on inflation volatility in developing countries with lower degrees of central bank independence and economic freedom. 相似文献

In the European Union, for the first time, lay people can participate directly in the procedure of assessment of GMO (genetically modified organisms) products, an exercise normally reserved for scientists and legal experts. What makes this a unique strategy of participation is that for each single application for authorization, lay people have the opportunity to express their views. This article presents the result of the first in‐depth analysis of this type of Internet participatory exercise in the first years of its implementation. It shows that, despite generally participatory technology assessment aims at deliberative consensus on technical questions, this forum is instead a way to expose the work of regulative authorities to public scrutiny and to express dissent and opposition to the European Commission policy on GMOs. 相似文献

In this article, we examine the difficult leadership position President Barack Obama inherited as he took office with respect to science and technology policy making and implementation, particularly following the Bush administration and years of the so‐called “war on science.” We contend that the Obama administration's challenge is not only to take substantive policy action, but also to reform certain administrative practices, particularly in light of the previous administration's practice of the politics of strategic vacancies, a managerial technique that rearranges an agency's ideological inclinations not through the usual forms of active politicization (i.e., by filling the appointee ranks with like‐minded ideologues) but instead by “starving” the agency of staff and co‐opting its agenda that way. 相似文献
