This paper reports on the findings of an in-depth genealogical study of the discourse of quality in Australian Early Childhood Education and Care (ECEC) policy. Quality reform has become the foremost global policy agenda for ECEC due to assumptions about the economic potentials of quality services. In Australia, the recent National Quality Framework elevated early childhood policy in Australia from the margins as the lynchpin of a broader economic reform agenda. However, quality ECEC – what it is and does – is a complex, contestable notion that could be considered problematic for the sector to execute, particularly through market models of provision. Drawing on Foucauldian notions of discourse as the ‘already said’, the truth assumptions that have underpinned policy uses of quality ECEC in Australia are identified and critiqued. It is shown that the discourse of quality has been tactically deployed in Australian ECEC policy to realign quality ECEC outcomes with educative outcomes, as a means for government to selectively grow and govern human capital. This positions quality as a high-stakes reform discourse for early childhood stakeholders, entwined with the expanded reach and intensification of selective, performance-related standards and incentives. 相似文献

Child maltreatment (CM) in foster care settings (i.e., institutional abuse, IA) is known to have negative effects on adult survivor’s mental health. This study examines and compares the extent of CM (physical, emotional, and sexual abuse; physical and emotional neglect) and lifetime traumatization with regard to current adult mental health in a group of survivors of IA and a comparison group from the community. Participants in the foster care group (n = 220) were adult survivors of IA in Viennese foster care institutions, the comparison group (n = 234) consisted of persons from the Viennese population. The comparison group included persons who were exposed to CM within their families. Participants completed the Childhood Trauma Questionnaire, the Life Events Checklist for DSM-5, the PTSD Checklist for DSM-5, the International Trauma Questionnaire for ICD-11, and the Brief Symptom Inventory-18 and completed a structured clinical interview. Participants in the foster care group showed higher scores in all types of CM than the comparison group and 57.7% reported exposure to all types of CM. The foster care group had significantly higher prevalence rates in almost all mental disorders including personality disorders and suffered from higher symptom distress in all dimensional measures of psychopathology including depression, anxiety, somatization, dissociation, and the symptom dimensions of PTSD. In both groups, adult life events and some but not all forms of CM predicted PTSD and adult life events partly mediated the association of PTSD and CM. Explanations for the severe consequences of CM and IA are discussed. 相似文献

The school transition model suggests that children's transitions into formal schooling can have lasting and profound implications for their educational careers, though this model is rarely used to understand the outcomes of children of immigrants. Using data from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K), a nationally representative sample of kindergarteners in 1998–1999, we examine the pre-kindergarten child care arrangements of children of immigrants and how these care arrangements are associated with children's behavior. We find that minority and immigrant children are less likely than their native-born white counterparts to be enrolled in center-based care and other care, compared to parental care, prior to kindergarten. We also find that ethnic origin is an important predictor of child care usage. Finally, though center-based care, on average, is not independently associated with children's behavior in kindergarten, the association between center-based care and behaviors varies by race and immigrant status. Broadly, these findings underscore the importance of understanding how native- and foreign-born children experience the transition to schooling, a critical period in the life course. 相似文献

Caregivers’ use of metacognitive language in child care centers: Prevalence and predictors 总被引:1,自引:0,他引:1

Use of metacognitive language by child care center staff in classrooms that serve preschool-aged children was examined. Staff's use of mental-state talk, perspective-taking talk, and activity-relevant questioning with children were coded in a series of 20-s snapshots taken over the course of one full morning per classroom. A total of 3401 snapshots were observed for 393 teachers in 103 classrooms. Staff used mental-state talk in 22% of the snapshots, activity-relevant questions in 12%, and perspective-taking talk in 3%. Structural and process predictors of staff's metacognitive language were examined for full-time staff (n = 148 in 95 classrooms) using multilevel modeling and ordinary least squares regression. Caregiver positive interaction style predicted caregivers’ engagement in all three types of language. Caregiver punitive interaction style was also a positive predictor of caregivers’ talk about others’ perspectives. In general, structural characteristics of the classroom were not significant predictors of staff's language. However, the proportion of children receiving a child care subsidy in the center negatively predicted perspective-taking discourse. Results indicate the importance of caregiver relational style in providing a more discourse-rich child care context. 相似文献

An important aspect of the transnational lives of Polish migrants in the Netherlands is their frequent use of healthcare services in Poland. Transnational care use may be detrimental for the continuity and the quality of the care migrants receive. The current study aims to shed light on the antecedents of migrants' doctor visits in Poland. Drawing on a representative population-based sample of Polish migrants in the Netherlands (n = 1,082), logistic regression is used to assess whether length of stay in the Netherlands is negatively associated with the likelihood of doctor visits in Poland. The KHB decomposition method is used to determine the extent to which this potential association is mediated by three specific acculturation factors: ethnic identification, trust in the Dutch healthcare system and Dutch language proficiency. The models show that migrants who stayed in the Netherlands longer were less likely to visit doctors in Poland. Mediation analyses indicated that this effect was largely attributable to their greater Dutch language proficiency compared to their counterparts who arrived in the Netherlands more recently. Strong ethnic self-identification as Polish and lower trust in the Dutch healthcare system were also associated with a higher likelihood of visiting doctors in Poland. However, no significant mediation of the effect of length of stay via ethnic self-identification or Dutch language proficiency was found. The findings suggest that voluntary language programs may foster inclusion of Polish migrants in the Dutch healthcare system and reduce the need migrants perceive to seek care in their country of origin. 相似文献
