The purpose of the present study was to understand, from parents' perspectives, the process of entry to community‐based services for children with developmental disabilities and to explore the relationship between patterns of entry and parent‐reported needs and priorities for service. Qualitative interviews were conducted with 43 mothers and 29 fathers of children with developmental disabilities approximately 6 months after the families entered community‐based childhood disability support services in Manitoba, Canada. Analysis of the coded interview data resulted in the identification of three process factors influential in the entry of families to community‐based support services: recognition of problems in child development, formal diagnosis of child disability and linkage between diagnostic services and the community‐based support system. Analysis of these processes identified four patterns of service entry associated with differing family needs for service: early entry, prompt entry, delayed entry and atypical entry. The results can be understood as a typology useful for social workers in the assessment of family needs and priorities at the point of entry to community‐based services.  相似文献

Burnout is a frequent and well-documented consequence of social work practice. The literature suggests that mindfulness-based interventions might help develop the mental states and emotional skills that are indicators of resilience. This mixed-methods, non-randomised controlled, exploratory study with 14 social workers in Canada investigated differences in social workers’ levels of stress, resilience, and burnout after a mindfulness-based intervention, compared to a waitlist group. The intervention group was also interviewed about changes in their relationships within the workplace, their perceived sense of mental health, and wellbeing. Results suggested that the mindfulness-based intervention significantly decreased the treatment group’s perceived stress compared to those on the waitlist and continued to decline for 26 weeks post-intervention. Intervention participants reported positive changes in attitudes, perspectives, behaviours, and energy in relation to their workplace relationships with peers and supervisors. Mindfulness-based interventions for reducing stress and building resilience to burnout in social workers and other helping professionals hold promise, and invite further research.  相似文献

Accurate volatility forecasting is a key determinant for portfolio management, risk management and economic policy. The paper provides evidence that the sum of squared standardized forecast errors is a reliable measure for model evaluation when the predicted variable is the intra-day realized volatility. The forecasting evaluation is valid for standardized forecast errors with leptokurtic distribution as well as with leptokurtic and asymmetric distributions. Additionally, the widely applied forecasting evaluation function, the predicted mean-squared error, fails to select the adequate model in the case of models with residuals that are leptokurtically and asymmetrically distributed. Hence, the realized volatility forecasting evaluation should be based on the standardized forecast errors instead of their unstandardized version.  相似文献

It has been proposed that the negative association between wives' earnings and their time in housework is due to greater outsourcing of household labor by households with high-earning wives, but this hypothesis has not been tested directly. In a sample of dual-earner married couples in the Consumption and Activities Mail Survey of the Health and Retirement Study (N = 796), use of market substitutes for women's housework was found to be only weakly associated with wives' time cooking and cleaning. Furthermore, expenditures on market substitutes explain less than 15% of the earnings-housework time relationship. This suggests that use of market substitutes plays a smaller role in explaining variation in wives' time in household labor than has previously been hypothesized.  相似文献

From 2005 through 2008, we undertook a participatory research project involving graziers from 8 farms in Southern Wisconsin, all of whom practice management intensive grazing. We used semi-structured interviews and participant observation during research and field days to investigate graziers’ engagement with university research. Grazing farms demonstrate rich variability and individuality as a result of their position within a number of biophysical and social contexts. Graziers emphasized the importance of finding ways to work with the variables of their specific context, rather than trying to control that variability. This effort entails the development and use of local knowledge, as graziers respond to the idiosyncrasies of their farms. It also leads graziers to reject mainstream agricultural research that has produced formulas for agricultural uniformity. The picture of grazing that emerged from our interviews leads us to propose the search for agroecological principles and agroecological tools, embedded in context, as an alternative to conventional research. We argue that this proposal speaks to the greater conundrum of how to relate the general knowledge of science to the place-specific, experience-based knowledge of grass-based farmers.  相似文献
