Responding adequately to parental priorities for child care is important for shaping children’s early experiences and development, and for facilitating parenting at the nexus of work and caregiving roles. Although much research on child care choice has relied on variable-centered approaches that treat parental priorities as distinct and isolated, this article aims to understand parents’ care choices from a person-centered, holistic perspective. Using data from the National Household Education Survey of Early Childhood Program Participation of 2005 (n = 4570), we conduct latent class and multinomial logistic regression analyses, identifying four empirically and substantively distinctive classes of parents based on their scores on seven indicators of child care priority. Class 1 parents (35%) rank all seven indicators as very important. Class 2 parents (18%) prioritize practicality factors. Class 3 parents (9%) do not, on average, rank any of the indicators as highly important. Class 4 parents (37%) emphasize learning and quality-focused factors. Class membership is associated with child’s age, race/ethnicity, and parent respondent’s gender, age, employment status, and socio-economic status. After controlling for socio-demographic factors, parents in the learning-focused class are more likely to choose center-based cares whereas practicality-focused parents prefer home-based relative or non-relative care arrangements. 相似文献

Latinos have become the largest minority group in American postsecondary education, a majority of whom attend two- or four-year Hispanic-Serving Institutions (HSIs). However, little is known about labor market outcomes as result of attending these institutions. Using a unique student-level administrative database in Texas, and accounting for college selectivity, we examine whether attending an HSI influences labor market outcomes ten years after high school graduation for Latino students in Texas. We find no difference in the earnings of Hispanic graduates from HSIs and non-HSIs. This analysis represents one of the first to examine the labor market outcomes for Latino students in this sector of education accounting for critical factors that include a student’s high school and community context. 相似文献

Care in teaching has been widely investigated; however, little research has sought secondary pre-service teachers’ understandings of caring and their potential responsibility to care for students. Accordingly, semi-structured interviews were employed with four focus groups, involving 12 (2 male and 10 female) participants. Data were analysed within a qualitative paradigm using Interpretative Phenomenological Analysis (IPA) and inter-rater reliability. Five overlapping themes were identified, and although many tensions around the ambiguities of establishing appropriate boundaries to care were shown, caring was deemed central by the participants to being effective teachers. Overall, pre-service secondary teachers agreed that neither pedagogy nor discipline strategy would be effective without care. Training implications and suggestions for future research conclude this paper. 相似文献

Hornik and Woolf (1999) proposed using cross-sectional survey data to prioritize beliefs to address with communication campaign messages. The empirical component of the approach combines evidence of (1) association of beliefs with intentions and (2) current level of beliefs to calculate a “percentage to gain” as the potential promise of a belief. However, the method relies on cross-sectional data; its conclusions are open to challenge. Here, a panel study assesses whether the calculated promise of a belief actually predicts future behavior change. A nationally representative sample of 3,204 U.S. youth and young adults were interviewed twice, six months apart. Sixteen beliefs about the benefits and costs of smoking cigarettes are compared with regard to their percentage to gain (calculated from cross-sectional data) and their ability to account for subsequent cigarette use. A belief’s cross-sectional percentage to gain is substantially associated with its ability to predict subsequent behavior change (r = .53, p < .05). 相似文献

The Action on Principled Pedagogy and Learning Evaluation (APPLE) project is a cross cultural study of teaching in primary/elementary schools in England and North Carolina. The study is focused on variance in teaching, how teaching differs from the best, or most effective, that it might be, and on the relationship between professional knowledge for teaching and teachers' roles and actions. The major products of this study were: (a) a set of 16 dimensions of teaching and a model for analysis of the degree to which each dimension is an asset or barrier to learning in any given instruction and (b) a new typology of teaching, based on variance from the best that could be rather than in comparison to others. In this article we describe, briefly, the APPLE project, present the dimensions and the new typology and discuss their implications for the professionalisation of teaching. In particular, the finding that even amongst the best teachers, the ability to articulate practice in a clear, technical language is rare, is, it is argued, a major barrier to the definition of teaching as a professional activity. 相似文献

Inertial microfluidics is an emerging class of technologies developed to separate circulating tumor cells (CTCs). However, defining design parameters and flow conditions for optimal operation remains nondeterministic due to incomplete understanding of the mechanics, which has led to challenges in designing efficient systems. Here, we perform a parametric study of the inertial focusing effects observed in low aspect ratio curvilinear microchannels and utilize the results to demonstrate the isolation of CTCs with high purity. First, we systematically vary parameters including the channel height, width, and radius of curvature over a wide range of flow velocities to analyze its effect on size dependent differential focusing and migration behaviors of binary (10 μm and 20 μm) particles. Second, we use these results to identify optimal flow regimes to achieve maximum separation in various channel configurations and establish design guidelines to readily provide information for developing spiral channels tailored to potentially arbitrary flow conditions that yield a desired equilibrium position for optimal size based CTC separation. Finally, we describe a fully integrated, sheath-less cascaded spiral microfluidic device to continuously isolate CTCs. Human breast cancer epithelial cells were successfully extracted from leukocytes, achieving 86.76% recovery, 97.91% depletion rate, and sustaining high viability upon collection to demonstrate the versatility of the device. Importantly, this device was designed without the cumbersome trail-and-error optimization process that has hindered the development of designing such inertial microfluidic systems. 相似文献
