Young children rely on their parents for making decisions about their child care experiences. Parents' child care arrangements are affected by the information they gather, their values and childrearing beliefs, their knowledge of child care quality, and the extent to which they are satisfied with their child care choices. Parents' decisions about child care are also influenced by ecological correlates, such as child age, maternal education and hours of employment, family ethnicity and income, and state and federal child care policies. This review addresses each of these elements and their role in parents' child care arrangements and concludes with recommendations for honoring parents' child care ideals through better child care quality information and higher professional standards for child care providers. 相似文献

We conducted four experiments in order to investigate whether pigeons' responses to a recently attended (i.e., recently pecked)
location are inhibited. In Experiments 1 and 2, stimulus displays were similar to those used in studies of inhibition of return
(IOR) with humans; responses to cued targets tended to be facilitated rather than inhibited. In Experiments 3 and 4, birds
were presented with stimulus displays that mimicked clusters of small grains and were relatively localized, which should have
been more appropriate for detecting IOR in pigeons. The results from these experiments again provided evidence for facilitation
of responding to cued targets, rather than for IOR. 相似文献

This paper describes the results from a qualitative study of 72 preservice teachers’ initial ideas about contextualizing science instruction with language minority students. Participants drew primarily on local ecological and multicultural contexts as resources for contextualizing instruction. However, preservice teachers enrolled in the bilingual certification program articulated more asset-oriented and less stereotypical ideas than those not seeking bilingual certification. Results can inform teacher education programs that aim to prepare graduates for teaching science in multilingual classrooms. 相似文献

This paper interrogates the case for improved and broadened public sustainability reporting by universities, and explores whether and how global performance measures capture the institutional attitudes and activities pertinent to universities’ contributions to sustainability. The analysis explores all stand-alone, English language reports produced by universities world-wide since 2007. The analysis focuses primarily on the Global Reporting Initiative (GRI) index. The paper finds that those universities which have adopted the GRI share a distinct conceptualisation of their role in society. The GRI framework is helpful in capturing universities’ environmental impacts and benefits, but is lacking in relation to universities’ human rights and social concerns. The paper identifies value in universities adopting a globally accepted sustainability reporting framework and makes specific suggestions as to how the framework might be better adapted for universities. 相似文献

The aim of the National Numeracy Strategy is to raise standards in numeracy. Strong evidence for its success has, however, been lacking: most of the available data come from performance on National Test assessments administered in schools or from Ofsted reports, and is vulnerable to suggestions of bias. An opportunistic analysis of data from a population cohort study extending over three school years compares school‐based scores at school entry and at age 7–8 with clinic‐based scores on similar tests. The results show a small but statistically significant rise between 1998 and 1999 and between 1998 and 2000 in scores on both KS1 arithmetic SATs taken in schools and the arithmetic component of the WISC test taken in an independent research clinic. This is evidence for a real rise in generalised arithmetic ability over this period which may be attributable to the children's experience of the National Numeracy Strategy. 相似文献

We describe a technology based on lamination that allows for the production of highly integrated 3D devices suitable for performing a wide variety of microfluidic assays. This approach uses a suite of microfluidic coupons (“microfloupons”) that are intended to be stacked as needed to produce an assay of interest. Microfloupons may be manufactured in paper, plastic, gels, or other materials, in advance, by different manufacturers, then assembled by the assay designer as needed. To demonstrate this approach, we designed, assembled, and characterized a microfloupon device that performs sodium-dodecyl-sulfate polyacrylamide gel electrophoresis on a small sample of protein. This device allowed for the manipulation and transport of small amounts of protein sample, tight injection into a thin polyacrylamide gel, electrophoretic separation of the proteins into bands, and subsequent removal of the gel from the device for imaging and further analysis. The microfloupons are rugged enough to handle and can be easily aligned and laminated, allowing for a variety of different assays to be designed and configured by selecting appropriate microfloupons. This approach provides a convenient way to perform assays that have multiple steps, relieving the need to design highly sophisticated devices that incorporate all functions in a single unit, while still achieving the benefits of small sample size, automation, and high speed operation. 相似文献
