This study investigated school factors that impact attendance. Interviews and focus groups with over 60 key stakeholders from five Maryland counties were conducted. Respondents indicated that despite individual, family, and community factors that contribute to non-attendance, students will attend a school that is intentional about creating a welcoming climate that is supportive and academically stimulating. Attendance can be improved when schools evaluated policies that may unintentionally deter student attendance, when students feel heard by school personnel, and when students are given opportunities to establish supportive relationships with caring adults in and out of the classroom.  相似文献

A case study in Cape Town, South Africa, explores the right to health for signing Deaf 1 1. By Deaf (capitalised) we understand those permanently sensorily disabled people who are born deaf or who become deaf as children and whose first language is sign – South African Sign Language (SASL) in this country. View all notes patients attending health services and who are unable to communicate in a language they understand. It argues that, without language, Deaf South Africans’ dignity and right to health is violated, resulting in serious consequences such as incorrect diagnosis, improper treatment and standard of care not being applied. It critiques the provisions of the Convention on the Rights of Persons with Disabilities (CRPD) and the limits of General Comment 14 of the International Covenant on Economic, Social and Cultural Rights. The paper demonstrates that Deaf patients do not have informational access to healthcare. It argues that language via professional interpreter services is essential to their South African constitutional right of access to healthcare. General Comment 14 addresses informational accessibility, but this is insufficient without addressing language as a pre-requisite. The CRPD imposes on the South African government human rights obligations to provide professional interpreter services for Deaf people, but unfortunately it allows a loophole by enabling cost to serve as reasonable grounds to defer action.  相似文献

The association between parental military work factors and adolescent's well‐being was examined. Data were collected from 1036 military youth. Using a within‐group design, we examined adolescent's well‐being related to parental absence, school and neighbourhood transitions, paygrade/rank and participation in military‐sponsored activities, and differentiated outcomes by sex and age. Two parental work factors primarily influenced adolescent's well‐being, parental paygrade/rank and engagement in military‐sponsored activities. Parental paygrade/rank was the only factor uniformly related to poorer well‐being, and this variable likely represents a more complex set of family circumstances. Engaging in military‐sponsored activities served as a resource and was related to enhanced well‐being. Individual‐level differences and implications for social workers are discussed.  相似文献

Over the years, cognitive biases have been examined throughout the decision-making literature, but little work has investigated the cognitive biases operating in ethical decision making. The present effort explores a taxonomy of biases through interviews with university faculty members. Additionally, this study identifies the psychological processes giving rise to these biases in ethical decision making. Results suggest that the biases listed in the taxonomy are indeed operating in the ethical decision making of university faculty. Implications of these results are discussed.  相似文献

Methods for constructing simultaneous confidence intervals for contrasts of treatment effects in analysis of covariance (ANCOVA) models are discussed and compared. A simple procedure is given by which, under a normality assumption made on the covariates, any method appropriate in an analysis of variance (ANOVA) may be applied to a corresponding ANCOVA by means of a simple adjustment of the required critical values. Some properties of this procedure are noted.  相似文献

In this paper a test for model selection is proposed which extends the usual goodness-of-fit test in several ways. It is assumed that the underlying distribution H depends on a covariate value in a fixed design setting. Secondly, instead of one parametric class we consider two competing classes one of which may contain the underlying distribution. The test allows to select one of two equally treated model classes which fits the underlying distribution better. To define the distance of distributions various measures are available. Here the Cramér-von Mises has been chosen. The null hypothesis that both parametric classes have the same distance to the underlying distribution H can be checked by means of a test statistic, the asymptotic properties of which are shown under a set of suitable conditions. The performance of the test is demonstrated by Monte Carlo simulations. Finally, the procedure is applied to a data set from an endurance test on electric motors.  相似文献

Ridge versions of an ill-conditioned system are alleged to “act more like an orthogonal system” than the system itself. Alternatives, called surrogates and based on the conditioning of linear systems, are shown to yield smaller expected mean squares than OLS, and uniformly smaller residual sums of squares than ridge. Ridge and surrogate solutions are compared on several marques of orthogonality to include conditioning of dispersion arrays, variance inflation factors, isotropy of variances, and sphericity of contours of the estimators. For these, ridge typically exhibits erratic divergence from orthogonality as the ridge scalar evolves, often reverting back to OLS in the limit. In contrast, surrogate solutions converge monotonically to those from orthogonal systems. Invariance considerations constrain the computations to models in canonical form. Case studies serve to illustrate the central issues.  相似文献

Jensen C. The forgotten half: analysing the politics of welfare services Int J Soc Welfare 2011: 20: 404–412 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and the International Journal of Social Welfare. This article discusses the welfare state and argues that the service component has been neglected in the mainstream literature. A main reason for the neglect is the lack of theorising on the distinction between the politics of welfare services and the politics of transfers. An analytical framework that may help overcome this problem is presented.  相似文献

Abstract Underemployment, which goes beyond unemployment to include the working poor, discouraged workers, and involuntary part-time workers, is a useful measure of employment hardship. We argue that underemployment should be included with other conventional indicators of the disadvantaged circumstances of nonmetropolitan (nonmetro) labor, in terms not only of prevalence, but also of the likelihood of transitions into and out of underemployment. We take advantage of the quasi-longitudinal nature of the U.S. Current Population Surveys to estimate models of year-to-year employment transitions for the quarter century 1968 to 1993. We find that (1) adequately employed nonmetro workers are more likely than their more urban counterparts to become underemployed; (2) the nonmetro underemployed are less likely to become adequately employed; (3) statistical controls only strengthen these nonmetro disadvantages; (4) the employment transitions of nonmetro workers are less affected by shifts in the direction of the national economy than are those of metro workers; and (5) nonmetro women are more disadvantaged than women residing elsewhere.  相似文献
