This article describes the innovative use of a pop culture source-song lyrics to augment the teaching of qualitative methods in social work research. The use of pop culture sources as learning tools in the MSW curriculum has the potential to enhance the learning experience for students. These techniques have not been applied in the content of MSW research classes. This approach could be advantageous over other typical data sources because it is more accessible to students while also being reflective of a collective identity of people in society. Future work should assess student and educator responses to this pedagogical approach.  相似文献

The contributions that adult men and women make to households in terms of paid and unpaid work have undergone substantial change, particularly in respect of women's responsibility for income generation, and have been seen as part of the processes of individualization. Recent contributions to the literature have suggested that children are now acquiring independence earlier as part of those same processes. The paper uses qualitative methods to explore the way in which parents in two-parent families, where both are employed, perceive the risks attached to children's exercise of greater independence, how they seek to ‘manage’ those risks and how far the perceptions of parents accord with those of children. We find parents’ perceptions of risk to be strong, but to have little to do with working patterns. In addition, they are often at odds with the actual behaviour of the child. Risks are managed by negotiation, in which children played an active part. We are also able to make some preliminary comments on the difficulties of interpreting scale measures in relation to interview evidence.  相似文献

Parametric incomplete data models defined by ordinary differential equations (ODEs) are widely used in biostatistics to describe biological processes accurately. Their parameters are estimated on approximate models, whose regression functions are evaluated by a numerical integration method. Accurate and efficient estimations of these parameters are critical issues. This paper proposes parameter estimation methods involving either a stochastic approximation EM algorithm (SAEM) in the maximum likelihood estimation, or a Gibbs sampler in the Bayesian approach. Both algorithms involve the simulation of non-observed data with conditional distributions using Hastings–Metropolis (H–M) algorithms. A modified H–M algorithm, including an original local linearization scheme to solve the ODEs, is proposed to reduce the computational time significantly. The convergence on the approximate model of all these algorithms is proved. The errors induced by the numerical solving method on the conditional distribution, the likelihood and the posterior distribution are bounded. The Bayesian and maximum likelihood estimation methods are illustrated on a simulated pharmacokinetic nonlinear mixed-effects model defined by an ODE. Simulation results illustrate the ability of these algorithms to provide accurate estimates.  相似文献

Abstract

In 2012, the NGO Save the Children launched its No Child Born to Die campaign with the tagline, “Breastfeeding Saves Lives.” The press release explains that in the first hours and days after a baby is born, their mother produces colostrum, a substance known to improve immunity, which must be delivered to infants in the first sixty minutes of life; this is referred to as “the power of the first hour.” Invoking a sense of urgency and a crisis of infant mortality, which breastfeeding is positioned to resolve, the campaign cites staggering medical statistics of infant deaths in the campaign targets of Africa, Asia and Latin America, and also Northern Indigenous and Inuit reserves in Canada. More than misrepresenting racialized women in the developed world as uneducated on infant health, childcare and child rearing and as lacking agency and empowerment, the campaign mobilizes the erroneous conflation of medical science, morality, capitalism and public health – a linkage typically mobilized by the development industry to the detriment of globally marginalized women. In order to understand how this conflation is mobilized to manufacture crisis at the expense of examining the root causes of infant mortality globally, we collect theories of crisis temporalities to develop a “feminist politics of crisis.”  相似文献

Recently, there have been advances in the development of multidimensional poverty measures. Work is needed however on how to implement such measures. This paper deals with the process of selecting dimensions and setting weights in multidimensional poverty measurement using qualitative and quantitative methods in a participatory framework. We estimate the multidimensional poverty measures developed by Alkire and Foster for a particular group: persons with psychiatric diagnoses in the United States. To select relevant dimensions and their relative ordering, two discussion groups are convened: one consisting of persons with lived-experience expertise and the other consisting of people with mental health service provision or research expertise. Several methods are used to convert dimension rankings into weights. The selection and ordering of dimensions differed between the two discussion groups, as did the resulting poverty measures. For instance, the poverty headcount using the dimensions and weights of the ‘lived experience’ group ranged from 20.61 to 26.96% as compared to a range of 18.62–33.19% using those of the ‘provider/researcher’ group. One of the main results of this study is that the Alkire Foster method is sensitive to the selection of dimensions and the methods used to derive rankings and weights. It points toward the limitation of relying exclusively on small scale qualitative methods for the selection and ranking of dimensions. In addition, the participatory framework used in this study was found to be essential in interpreting results, in particular with respect to the limitations of the data set in measuring relevant dimensions.  相似文献

A societal decision to protect over 9 million acres of land and water for its wilderness character in the early 1960s reflected US wealth in natural resources, pride in the nation’s cultural history and our commitment to the well-being of future generations to both experience wild nature and enjoy benefits flowing from these natural ecosystems. There is no question that our relationship with wilderness has changed. Individually it is probably quite easy to examine differences in the role wilderness plays in the quality of our lives today compared to some previous time. But how the role of wilderness protection has changed for society is more difficult to describe. In only a few places do we have data across multiple decades that would allow us to even examine how users or their use may have changed over time. At the Boundary Waters Canoe Area Wilderness in northern Minnesota we are fortunate to have multiple studies that can give us some 40 years of insight into how some aspects of use have changed there. For example, an analysis of results of visitor studies at the Boundary Waters Canoe Area Wilderness in 1969, 1991 and 2007 reveal some big differences in who is out there today, most notably the presence of a much older, more experienced and better educated user population, almost exclusively white and predominantly male. It is time to decide whether the best thing for wilderness and or society is to try to restore historic patterns of use (to include younger people, the less wealthy and lower educated) in greater numbers, to try to identify new markets within growing underrepresented populations, or adapt our perception of wilderness stewardship to better include planning for emerging social values of a new generation with other indicators of well-being. A growing population with greater dependence on ecosystem services provided by protected nature could lead to wilderness protection becoming an important quantitative and qualitative element of quality of life indices in the very near future.  相似文献

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing  相似文献
