This article seeks to critically re-open the closed structure of news coverage of ethnic minorities by proposing a dialogical model of representation, which evokes mutual understanding across differences through well-crafted narratives of minority experiences. Informed by Mikhail Bakhtin and Charles Taylor, it explores the notion of “dialogue” within journalistic narratives and delineates two dialogical approaches, namely the evaluative articulation of moral values and the polyphonic incorporation of different voices. The former suggests that journalists should employ nuanced languages to situate ethnic minorities’ aspirations and experiences in a common “horizon of significance”. The latter challenges the hegemonic monologue of an ostensibly objective narration and accentuates the manifold voices from ordinary people, urging the journalists to rethink their positionality as narrators. Two cases are analyzed to reveal how the dialogic representation can be realized in news reporting, calling for a transition from “ethics of inarticulacy” to ethics of care in journalism practices.  相似文献

When children are placed into foster care the caseworker must give preference to an adult relative, many of whom are grandparents, over an unrelated caregiver. This kinship preference is based in evolutionary biology, which suggests that the imperative to care for a child should be greater for kin versus non-kin. However, not all kin are related to a child in the same way, and level of paternity uncertainty may influence level of care provided. For instance, maternal grandparents can be assured that they share genetic material with their grandchild, while paternal grandparents may not have the same level of certainty. Owing to the possibility of paternity uncertainty, we hypothesize that out-of-home placements with paternal grandparents will be at a greater risk of subsequent investigations than placements with maternal grandparents or with foster parents. We secured data on placements n = 560 of children ages 1.5 to 17 following a maltreatment investigation from a merger of the National Survey of Child and Adolescent Well-Being NSCAW II and the National Child Abuse and Neglect Data System NCANDS. Kaplan-Meier and multivariate Cox regression were used to examine the difference in time to the first new investigation by type of out-of-home placement while controlling for covariates. Consistent with our hypothesis, placements with paternal grandparents were at a higher risk of a subsequent investigations than placements with maternal grandparents or non-kin foster parents. Results suggest a need for further considerations of child safety in foster care based on genetic relatedness of caregivers.  相似文献

Adoption is one of a range of options that can provide children in out-of-home care with permanency when they are unable to be reunified with their birth parents. This paper reports on how the adoption of children from out-of-home care is understood by professionals involved in making decisions about the permanent placement of children in out-of-home care in Victoria, Australia, where adoption is rarely used. Data were collected through a single, face-to-face semi-structured interview with 21 professionals; eight child welfare specialists, eight adoption and permanent care specialists and five judicial officers. The adoption of children from out-of-home care was primarily understood as a child-centered practice that can afford children stability and a sense of belonging. Adoption was largely viewed as a voluntary process dependent upon the consent of a child’s birth parents. Adoption and permanent care specialists were the only group to refer to the dispensation of parental consent as a means of obtaining an adoption order. Most decision makers understood that contact between children and their birth parents is possible following adoption, but this was not understood by all judicial officers or all child welfare specialists. Children’s connection to their cultural heritage was viewed as important to the consideration of adoption for children in out-of-home care. This research provides insight into the foundations upon which decision makers may appraise adoption, within a hierarchy of options, as a potential outcome for children in need of permanency.  相似文献

This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals’ performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study’s inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p = .001), who were more familiar with consultation (p = .002), who had more positive attitudes and beliefs about consultation (p = .011) and who reported being more susceptible to the behavior (p = .001) and expectations/opinions (p = .025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals’ responses to CAN are discussed.  相似文献

Young children under 6 years old are over-represented in the U.S. child welfare system (CWS). Due to their exposure to early deprivation and trauma, they are also highly vulnerable to developmental problems, including language delays. High quality early care and education (ECE) programs (e.g. preschool, Head Start) can improve children's development and so policymakers have begun calling for increased enrollment of CWS-supervised children in these programs. However, it is not a given that ECE will benefit all children who experience maltreatment. Some types of maltreatment may result in trauma-related learning and behavior challenges or developmental deficits that cause children to respond to ECE settings differently. The current study uses data from a nationally representative survey of children in the U.S. child welfare system, the National Survey of Child and Adolescent Well-Being II, to assess whether young CWS-supervised children (N = 1,652) who were enrolled in ECE had better language development outcomes 18 months later than those not enrolled in ECE. We also explore whether the type of maltreatment that brought children to the CWS’ attention moderates the relationship between ECE and children's language development. After controlling for children's initial scores on the Preschool Language Scale (PLS-3), type(s) of maltreatment experienced, and child and caregiver demographics, we found that ECE participation predicted better PLS-3 scores at follow-up, with a positive interaction between ECE participation and supervisory neglect. ECE seems to be beneficial for CWS-involved children's early language development, especially for children referred to the CWS because they lack appropriate parent supervision at home.  相似文献

Foster parents need access to supports and resources in order to be satisfied with their caregiving role and continue providing foster care services. However, they often experience multiple demands in their role as a substitute caregiver that could lead to stress. Child behaviors especially may be a significant factor when considering sources of strain and may be a potential risk factor for negative outcomes such as dissatisfaction or the decision to discontinue providing foster care. The purpose of this study was to examine whether child disruptive behaviors moderated or influenced the nature or strength of the relationship between foster parent supports and satisfaction as a caregiver as well as intent to continue fostering. The sample consisted of 155 licensed foster caregivers from across the United States. Child behaviors served as a significant moderator between some types of supports and satisfaction. Implications for future research, practice, and policy are discussed.  相似文献
