ABSTRACTIn social work education there have been very few attempts to empirically capture and measure how professional training programmes prepare students to work with ‘race’ equality and cultural diversity issues. This paper interrogates the experiences and outcomes of anti-racist social work education and evaluates the pedagogic relevance and practice utility of teaching social work students about ‘race’, racism and anti-racism. The data presented in this paper suggests that it is possible to discover the situated experiences of learning about anti-racism and measure how this teaching can affect and lead to knowledge, skills and attitudinal change. The triangulated mixed methods evidence presented in this paper combines nomothetic and idiographic approaches with quantitative data for a matched pair sample of 36 social work students and uses non-parametric statistical tests to measure at two time intervals (before and after teaching); knowledge, skills and attitudinal change. The paper explores how anti-racist social work education enables students to move from ‘magical consciousness’, where racism and racial oppression is invisible and thereby left unchallenged and maintained, to more critical and reflexive level of awareness where it is named, challenged and no longer shrouded in a culture of professional denial and silencing. 相似文献

The notion of minority community group (henceforth group) rights has become firmly entrenched in the constitutional vocabulary in many countries in recent years Yet liberal political theorists continue to define rights in individualistic terms. For some liberals, while it is meaningful to talk about individual rights, it is meaningless to talk about group rights. For communitarians, on the other hand, since individuals are embedded in some shared social context and since some groups do have legal and moral rights and responsibilities, it makes sense to speak of group rights. In some societies, community groups are treated as a unit‐‐potentially as a right‐and‐duty‐bearing unit. The paper attempts to show how some recent liberals attempt to justify group rights by recognising “culture” as a “primary good”, thus basing cultural rights on a foundation consistent with liberal theory. The “cases” selected for discussion attempt to illustrate how liberal societies have wrestled with linguistic group rights within individualistic liberal frameworks. 相似文献

Suppose that a density fθ (x) belongs to an exponential family, but that inference about θ must be based on data that are obtained from a density that is proportional to W(x)fθ(x). The authors study the Fisher information about θ in observations obtained from such weighted distributions and give conditions under which this information is greater than under the original density. These conditions involve the hazard- and reversed-hazard-rate functions. 相似文献

The present work suggests some effective linear combinations of exponential estimators to estimate the current population mean in two occasion successive sampling in presence of non response. Using the subsampling technique of non respondents, estimation procedures have been developed by utilizing information on an auxiliary variable, which is readily available on both occasions. Properties of the proposed estimation procedures have been examined and related optimum replacement strategies are suggested. Empirical studies are carried out to justify the preposition of estimators. Suitable recommendations have been made. 相似文献

The crux of this paper is to estimate the mean of the number of persons possessing a rare sensitive attribute based on the Mangat (1992) randomization device by utilizing the Poisson distribution in survey sampling. It is shown that the proposed model is more efficient than Land et al. (2011) when the proportion of persons possessing a rare unrelated attribute is known. Properties of the proposed randomized response model have been studied along with recommendations. We have also extended the proposed model to stratified random sampling on the lines of Lee et al. (2013). It has been also shown that the proposed estimator is better than Lee et al.'s (2013) estimator. Numerical illustrations are also given in support of the present study. 相似文献

Taking clue from the pioneer work of Singh and Sedory (2013), we have suggested a new stratified randomized response (RR) model. The properties of the suggested stratified RR model have been studied under proportional and “Neyman” allocations. The study has been also carried out in the presence of crude prior estimates. Numerical illustrations are also given in support of the present study. 相似文献

In this paper, an attempt has been made to present some efficient classes of estimators of population mean on current occasion in two-occasion successive sampling under random non response in two-phase setup. Effectiveness of the proposed classes of estimators has been studied under the assumptions that sampling units follow a distribution under the random non response. To check the performances, the proposed classes of estimators are compared with an estimator under the similar situation under the complete response. Results are demonstrated through empirical studies which show the reliable nature of the proposed classes of estimators. Suitable recommendations have been made to the survey practitioners. 相似文献

This article considers the problem of estimating the population mean on the current (second) occasion using multi-auxiliary information in successive sampling over two occasions. A general class of estimators is proposed for estimating population mean on the current occasion and expressions for bias and mean square error for these estimators are obtained up to first degree of approximation. The minimum variance bound estimator in the proposed class is discussed. Many popular estimators have been shown to belong to this class. Optimum replacement policy is also discussed. Finally, the superiority of the proposed class of estimators over multivariate version of chain type ratio estimator envisaged by Singh (2005) is established empirically. 相似文献

Present investigation deals with the problem of random non response in estimation of population variance on current occasion in two-occasion successive sampling. To reduce the negative impact of random non response on both occasions, regression type imputation method has been suggested. Using auxiliary information, efficient estimation strategies have been developed for estimation of population variance on the current occasion. Estimator for the population variance is also derived as a special case when random non response occurs only on the current occasion. Empirical studies are carried out to show the dominance of suggested estimators over sample variance and exponential type estimators. Results are interpreted. 相似文献

This paper addresses the problem of estimating the population variance S2y of the study variable y using auxiliary information in sample surveys. We have suggested a class of estimators of the population variance S2y of the study variable y when the population variance S2x of the auxiliary variable x is known. Asymptotic expressions of bias and mean squared error (MSE) of the proposed class of estimators have been obtained. Asymptotic optimum estimators in the proposed class of estimators have also been identified along with its MSE formula. A comparison has been provided. We have further provided the double sampling version of the proposed class of estimators. The properties of the double sampling version have been provided under large sample approximation. In addition, we support the present study with aid of a numerical illustration. 相似文献
