In this paper, a new single exponentially weighted moving average (EWMA) control chart based on the weighted likelihood ratio test, referred to as the WLRT chart, is proposed for the problem of monitoring the mean and variance of a normally distributed process variable. It is easy to design, fast to compute, and quite effective for diverse cases including the detection of the decrease in variability and individual observation case. The optimal parameters that can be used as a design aid in selecting specific parameter values based on the average run length (ARL) and the sample size are provided. The in-control (IC) and out-of-control (OC) performance properties of the new chart are compared with some other existing EWMA-type charts. Our simulation results show that the IC run length distribution of the proposed chart is similar to that of a geometric distribution, and it provides quite a robust and satisfactory overall performance for detecting a wide range of shifts in the process mean and/or variability. 相似文献

ABSTRACTThe importance of fathers' involvement in their children's lives is irrefutable. Supportive, warm, and positive involvement of fathers leads to children being well-adjusted. Indeed, involved fathers positively influence their children's cognitive ability, social behavior, psychological well-being, and educational achievement. For children in foster care, when fathers are involved they have significantly shorter stays in foster care than those whose fathers are not involved. For parents to demonstrate fitness to parent they must show the successful completion of goals specified in a case plan that promotes safety and permanence of their child. This cross-sectional study investigated how fathers' perception of social workers' attitude and practice skills was associated with fathers' understanding and confidence with regard to completing the case plan goals. A purposive sample of 56 child welfare-involved fathers completed the Child Welfare Father Involvement Questionnaire. The findings indicated that the more positive fathers perceived social workers' attitude and skills, the greater their understanding about the case plan goals and greater confidence to complete case plan goals. The results were statistically significant. These results have implications for child welfare training to build the social worker-client relationship in a compassionate manner while maintaining a rigorous assessment and monitoring of fathers' parenting capabilities. 相似文献

Abstract British cultural studies has, in an innovative and exciting way over the last three or four decades, opened up spaces for the serious analysis of many aspects of culture, including those inextricably related to questions of ‘race’, ethnicity and subordinated groups in urban environments in Britain. However, there have been a number of weaknesses and omissions with regard to Britain's black, Caribbean-descended population. Some of these are possibly the result of earlier, unresolved theoretical and methodological disputes within the field of cultural studies; others stem, perhaps, from an over-reliance on approaches arising out of youth subcultural analytical frameworks. Consequently, less than the required attention has been paid to the active cultures of achievement developed by the adult, black working-class population of Caribbean descent in Britain from the 1950s to the 1990s. 相似文献

Abstract This study interviewed 115 MSWs with substance abuse training working in general social service agencies to determine if they viewed their settings as facilitating or hindering their work with substance-abusing clients. This study builds on the work of Lightfoot and Orford (1986) who found that social workers were more hindered than helped by their agencies' practices regarding substance-abusing clients. Results: A majority of workers viewed their agencies as facilitating substance abuse-related work through support from supervisors and administrators, availability of substance abuse training, workers' freedom to choose clients, and opportunities to supervise others on substance abuse-related issues. Supervisor data corroborated these findings. This is a hopeful sign for the profession contrasting with considerable social work literature documenting the profession's historic ambivalence toward substance-abusing clients. 相似文献

ABSTRACTIn the era of global workflows and massive migrations, it has been suggested that the notion of home is breaking free from its material aspects to become a set of exportable routines and practices. On the other hand, it is argued that the materiality of spaces and objects can support migrants' well-being in the new destination. Drawing on the ethnography of a Moroccan household in Rome, Italy, we illustrate how actions pertinent to the material home can favor identity development and the exercise of agency. First, we discuss squatting as a collective action of appropriation and transformation, which led to the identification with a transnational, intercultural category of migrant. Second, we illustrate the activities of furnishing as the locus of syncretic and reflexive processes, in which elements of the host country and themes from the migratory experience are mixed and reinterpreted in novel ways. Our analysis supports the view that the materiality of the home and the actions it affords play a major role in the socio-psychological adjustment of migrants and—on a wider scale—in processes of cultural dynamism and renovation. 相似文献

ABSTRACT This paper considers the academic achievement gap between African American and White students at the elementary and high school levels. It attempts to determine if race or lower socioeconomic status impact results of standardized test results at high performing and low performing schools. It presents research involving regression analysis of data for the state of Illinois. Results indicate race is not a negative factor at high performing or low performing schools for both elementary or high school years, given the samples. Also, low socioeconomic status is not a negative factor at high performing or low performing schools for both the elementary and high school years. High performing schools had low to moderate quantities of the identified variables, while low performing schools had high levels of the identified variables. Societal biases toward Blacks-rich or poor-are challenged in this paper. 相似文献

ABSTRACT This article reports the results of a longitudinal study of the changing openness-related practices of private U.S. adoption agencies. Staff from private adoption agencies were interviewed at three points in time, in 1987–89, 1993, and 1999, about their current practices and attitudes regarding openness in adoption and any changes that may have taken place since the previous interview. From 1993 to 1999 agencies continued a trend toward offering and encouraging more open adoptions. During this period fully disclosed arrangements became more common and had the greatest growth since 1987, while confidential adoptions continued to decrease in frequency. Mediated adoptions remain the predominant arrangements. Changes in the adoption options offered by the agencies at all three time periods have been driven primarily by the demands of the birthmother for greater openness. However, by final data collection in 1999, most agencies in this sample changed from viewing the birthmother as their primary client to viewing the adopted child as their primary client. Implications for agency practices are discussed. 相似文献

AbstractThe 2006 war in Lebanon that erupted between Hezbollah and Israel marked the largest evacuation of Americans abroad since World War II. This article captures the experiences of Lebanese-American women and investigates how gender identity was expressed during these evacuations. Presented from the point of view of a participant-observer and personal interviews, findings show that gender became a master identity that influenced these women's choices regarding how to escape the country and return to the United States. Some embraced dependency upon masculinist exercises of power while others claimed agency as they determined their own fate and carried out their own evacuation without waiting to be rescued by the state or male kin members. The evacuation stories in this article confirm and illuminate the complexity of ethnic citizenship and gendered agency. 相似文献

The use of images is central to Amnesty International's 2004 campaign ‘Stop Violence against Women’. Looking at how Amnesty International uses images to show women's agency reveals a conflation of the terms sex and gender. Despite its best efforts, Amnesty International's goal of empowering women ultimately remains out of reach because it fails to read violence against women in a gendered context. Through interviews and analyses of the images, this article claims that Amnesty International's concept of agency is trapped in a heterosexist, masculinist grammar that perpetuates non-agential articulations of women in human rights discourse. This article offers an alternative reading of gender and agency that contextualizes violence, opening up spaces in human rights discourse to begin to look at what causes individuals to resort to violence and at how violence may be perpetrated because of the presence of particular genders. 相似文献
