In 2005 the Texas 79th legislature passed Senate Bill 6, which included mandates to address disproportionality. This article will describe how the Texas Department of Family Protective Services in collaboration with Casey Family Programs' Texas State Strategy systems improvement initiative is addressing disproportionality statewide through promising practices and innovations in undoing racism trainings, values-based leadership development, and community engagement strategies. 相似文献

The identification of members of a visible minority in early twentieth century Britain not only shows something of their participation in working class life but also that black people were not solely resident in towns and cities. As Britain was highly urbanized, the presence of such migrants in rural areas suggests that the number of black people in Britain was higher than has been assumed. 相似文献

Student assessment is an important component of social work education, and consumes considerable effort on behalf of both students and staff members. Social work educators in higher education face the challenge of constructing assessment methods, which encourage the development of reflective and critical learning, as well as enabling students to demonstrate acquisition of required knowledge and/or skills. While there is now a substantial literature on field education, the assessment of classroom-based units has warranted less attention. This paper examines the range of assessment methods reported in the social work education literature, the evidence which supports the use of these methods and issues associated with the identified assessment methods. 相似文献

This study documented the parenting styles among African migrants now living in Melbourne, Victoria, Australia, and assessed how intergenerational issues related to parenting in a new culture impact on family functioning and the modification of lifestyles. A total of 10 focus group discussions (five with parents and five with 13–17‐year‐old children; N = 85 participants) of 1.5–2 hours duration were conducted with Sudanese, Somali and Ethiopian migrant families. The analysis identified three discrete themes: (i) parenting‐related issues; (ii) family functioning and family relations; and (iii) lifestyle changes and health. African migrant parents were restrictive in their parenting; controlled children's behaviours and social development through strict boundary‐setting and close monitoring of interests, activities, and friends; and adopted a hierarchical approach to decision‐making while discouraging autonomy among their offspring. Programmes seeking to improve the health and welfare of African migrants in their host countries need to accommodate the cultural and social dimensions that shape their lives. Such programmes may need to be so broad as to apply an acculturation lens to planning, and to assist young people, parents and families in addressing intergenerational issues related to raising children and growing up in a different social and cultural milieu. 相似文献

Ridge regression is often discussed as an estimation procedure for producing estimators which are biased but with a smaller mean squared error than the usual least square estimators. In this paper we show that this procedure can also be used to reflect the nature of dependency among a set of highly collinear regressor variables. In particular, we prove that, when data are severely multicollinear, the ridge estimators can be made very close to the principal component estimators. Examples are given to illustrate the point. 相似文献

Invasive aspergillosis (IA) is a major cause of mortality in immunocompromized hosts, most often consecutive to the inhalation of spores of Aspergillus. However, the relationship between Aspergillus concentration in the air and probability of IA is not quantitatively known. In this study, this relationship was examined in a murine model of IA. Immunosuppressed Balb/c mice were exposed for 60 minutes at day 0 to an aerosol of A. fumigatus spores (Af293 strain). At day 10, IA was assessed in mice by quantitative culture of the lungs and galactomannan dosage. Fifteen separate nebulizations with varying spore concentrations were performed. Rates of IA ranged from 0% to 100% according to spore concentrations. The dose‐response relationship between probability of infection and spore exposure was approximated using the exponential model and the more flexible beta‐Poisson model. Prior distributions of the parameters of the models were proposed then updated with data in a Bayesian framework. Both models yielded close median dose‐responses of the posterior distributions for the main parameter of the model, but with different dispersions, either when the exposure dose was the concentration in the nebulized suspension or was the estimated quantity of spores inhaled by a mouse during the experiment. The median quantity of inhaled spores that infected 50% of mice was estimated at 1.8 × 104 and 3.2 × 104 viable spores in the exponential and beta‐Poisson models, respectively. This study provides dose‐response parameters for quantitative assessment of the relationship between airborne exposure to the reference A. fumigatus strain and probability of IA in immunocompromized hosts. 相似文献

Although performance-based contracts have become increasingly popular in child welfare, administrators are developing these contracts with little empirically guided information about how internal work conditions may influence the services families receive. This study examines how child welfare caseworker role overload moderates associations between child welfare agencies' use of performance-based contracting and services provided to families. Analyses using data from the National Survey of Child and Adolescent Well-Being suggest that when caseworkers experience high role overload, use of performance-based contracts may decrease caregivers' likelihood of receiving necessary social and behavioral health services. These findings and their implications are discussed. 相似文献

This research studies how organizational adoption of three different types of change – change in products, in technological processes and in administrative processes – is influenced by environmental factors such as industry regulation and market concentration and by the prior adoption of different types of change. We tested our hypotheses in the service sector, examining a sample of bank holding companies in the USA for the period 1975–1995. We found that (1) environmental factors influence rates of change in products, in technological processes and in administrative processes differently; (2) changes in products are followed by changes in both technological and administrative processes; and (3) the three types of change exhibit momentum, as firms are more likely to implement changes similar to those they have recently undertaken. We discuss the implications of our findings for the theory and management of change in organizations. 相似文献
