Cognitive outcomes at age 11 of 131 Romanian adoptees from institutions were compared with 50 U.K. adopted children. Key findings were of both continuity and change: (1) marked adverse effects persisted at age 11 for many of the children who were over 6 months on arrival; (2) there was some catch-up between ages 6 and 11 for the bottom 15%; (3) there was a decrease of 15 points for those over 6 months on arrival, but no differentiation within the 6-42-month range; (4) there was marked heterogeneity of outcome but this was not associated with the educational background of the adoptive families. The findings draw attention to the psychological as well as physical risks of institutional deprivation. 相似文献

In this article we present Supervised Semantic Indexing which defines a class of nonlinear (quadratic) models that are discriminatively
trained to directly map from the word content in a query-document or document-document pair to a ranking score. Like Latent
Semantic Indexing (LSI), our models take account of correlations between words (synonymy, polysemy). However, unlike LSI our
models are trained from a supervised signal directly on the ranking task of interest, which we argue is the reason for our
superior results. As the query and target texts are modeled separately, our approach is easily generalized to different retrieval
tasks, such as cross-language retrieval or online advertising placement. Dealing with models on all pairs of words features
is computationally challenging. We propose several improvements to our basic model for addressing this issue, including low
rank (but diagonal preserving) representations, correlated feature hashing and sparsification. We provide an empirical study
of all these methods on retrieval tasks based on Wikipedia documents as well as an Internet advertisement task. We obtain
state-of-the-art performance while providing realistically scalable methods. 相似文献

Framed in Michele Foucault's theories of discipline and technologies of the self, this paper explores the possibilities for teaching and researching across disciplinary boundaries within the academy. In Foucault's studies of systems of thought, he conceptualized practices – like sexuality – to be instances of what is possible to be, think, and do within a historical moment. In the ethnographic study reported on in this paper, we examined perceptions and practices of discipline-based academics seeking to work across traditional scholarly boundaries as instances of what was possible to be, think, and do in transdisciplinary teaching and research in higher education. Connecting transdisciplinary knowledge production with possibilities for critically engaging with sustainability as a social movement and imperative, we identify questions about and the promise of higher education as a place where this work can be done. 相似文献

The purpose of this study was to examine persistence in school among students with Foetal Alcohol Spectrum Disorder (FASD) from the perspectives of the students themselves and their parents. Tinto’s (1975, 1997) Student Integration Model (SIM) provided the theoretical framework for this research. This model involves an interplay between (1) background characteristics and attributes affecting the level of goal commitment, (2) level of academic integration, and (3) level of social integration into the institution that determine whether or not a student will graduate. The findings showed limited support for Tinto’s SIM and that parental advocacy is strongly linked with persistence among adolescents with FASD. A new model showing the parents’ role in encouraging persistence through their actions at home and advocacy at the schools is presented. 相似文献

Ethnic identity (EI) has long been known to supersede race as a predictor for attitudes and behaviors. However, little is known about the constituent parts that comprise and influence ethnic identity. In order to improve communications that target EI, we examine both demographic and communication variables to determine which have a greater pull on people’s attitudes and actions. Race appears to moderate the effects of age on ethnic identity, whereby age was negatively related to ethnic-identity exploration among White participants and positively related to ethnic identity commitment among Black participants (p < .05). Having a higher income, print-media use, and information-engagement orientation were also positively correlated with ethnic identity; education and gender were not. Implications and future directions are discussed. 相似文献

ABSTRACT: This paper considers the use of secondary data analysis in educational research. It addresses some of the promises and potential pitfalls that influence its use and explores a possible role for the secondary analysis of numeric data in the 'new' political arithmetic tradition of social research. Secondary data analysis is a relatively under-used technique in Education and in the social sciences more widely, and it is an approach that is not without its critics. Here we consider two main objections to the use of secondary data: that it is full of errors and that because of the socially constructed nature of social data, simply reducing it to a numeric form cannot fully encapsulate its complexity. However, secondary data also offers numerous methodological, theoretical and pedagogical benefits. Indeed by treating secondary data analysis with appropriate scepticism and respect for its limitations, by demanding that tacit assumptions about the unreliability of secondary data are applied equally to other research methods, and crucially by combining secondary data analysis with small-scale in-depth work, this paper argues for a return to prominence of secondary data analysis in its own right as well as becoming a central component of the new political arithmetic tradition of social research. 相似文献

A multilevel modeling approach was employed to investigate the relation between sex composition and developmental change in 70 urban preschool classrooms. The research represents a unique contribution as (1) few studies have examined the influence of sex composition during the preschool years, (2) it represents the first research to use a continuous (i.e., sex ratio) as opposed to binary (i.e., mixed- versus single-sex) indicator for classroom sex composition, and (3) the sample represents an important and often neglected group (i.e., low-income children from urban schools). A series of HLM models were run, addressing the nested nature of the data (children within classrooms), and relating classroom sex composition to developmental change using the cognitive, motor, and social subscales from the Child Observation Record (COR). Overall, there were no main effects at the classroom-level for sex composition. However, a cross-level interaction indicated that, while girls’ development was not influenced by classroom sex composition, boys in classrooms with proportionally more boys fared significantly worse in terms of development as assessed by combined score on the COR. More specifically, this interaction was significant when predicting the COR cognitive subscale, but nonsignificant when predicting the COR social and motor subscales. This was true when controlling for the number of students at the classroom-level, as well as child's age and baseline ability (i.e., Time 1 COR) at the child-level. Implications for early childhood education policy are discussed. 相似文献
