Asymptotic Minimax Risk for the White Noise Model on the Sphere

Estimation of an unknown function on the unit sphere of the Euclidean space is considered. The function is observed in Gaussian continuous time white noise. Uniform norm is chosen as a loss function and exact asymptotic minimax risk is derived extending the result of Korostelev (1993). The exact asymptotic minimax risk is also given for the L ₂-loss, applying the result of Pinsker (1980).     

Interviewing parents of children in care: Perspectives, discourses and accountability

The ‘parental perspective’ in child care work is a matter of concern and is actively solicited by practitioners, managers, policymakers and researchers for differing reasons. This paper argues that the search for such a stable “parental perspective” should be abandoned and suggest that research should embrace a social constructionist turn by concentrating on how parents' views are negotiated conversationally in discourse. Using data drawn from research interviews with parents of children in care and employing conversation and discourse analytic methods, the paper demonstrates how there are critical issues of accountability, blame, and testing at stake in the interview encounter, as interviewer and interviewee jointly produce a moral version of the client, the institution, the case and its attributes. The implications of this argument are delineated.     

Patterns and Predictors of Early Care and Education for Children in Foster Care

Patterns and predictors of center-based early care and education (ECE) of children in foster care were examined. Participants included 192 pre-Kindergarten age children in foster care. Foster parents reported demographics, ECE and other service use. Foster care history data was abstracted from case files. High rates of attendance in ECE prior to Kindergarten, including Head Start, other center-based ECE, or both were found. Children who attended Head Start were younger when first placed in foster care. Children who attended other center-based ECE services were more likely to live with kinship foster parents and foster families with higher incomes. Latent class analysis of ECE quantity, quality, type, and duration revealed three patterns: part-time Head Start, part-time other ECE, and full-time mixed ECE. Child and foster family characteristics predicted these patterns, illustrating distinct groups with potential implications for the development of children in foster care.
