The eight early childhood educators who participated in this study were admitted into a 60-credit statewide distance-delivered Associate of Applied Science (AAS) degree program at the University of Alaska. All eight educators were women of Alaska Native ancestry who lived and worked in remote and rural Native communities. Seven of these teachers were employed by Head Start programs and one taught preschool for a rural school district. A major goal of the statewide distance-delivered AAS program is that participants will become skilled observers of children and learn to use observation to make decisions that foster developmentally appropriate and culturally responsive services. All the course work in our AAS degree program involves actively doing and using observations of children. This study is based on a principle that intrinsic changes can occur in program management, curriculum development, and teacher practice when teachers learn how to use observation of children rather than external evaluation to make decisions about their programs. 相似文献

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as the Qinghai-Tibetan Plateau. We review research, including species catalogues; biodiversity monitoring; the origins, distributions, maintenance and threats to biodiversity; biodiversity-related ecosystem function and services; and species and ecosystems’ responses to global change. Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China''s vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations. Based on the recent rapid progress of biodiversity research, China is well positioned to become a global leader in biodiversity research in the near future. 相似文献

佛教中的体验与“家庭相似性”关联何在,为之辩护的论题包括两部分:(1)与其他方式相比,把皈依概念和神迹概念纳入体验概念可以使我们对佛教体验形成一种更为恰当的观点,而这一观点能够表明佛教的宣称与科学的经验主义的宣称之间的区别(前提1-10);(2)关于界定体验之所是的“家族相似性”理念,本文结论是,皈依与神迹是对佛教中的体验所作出的非实在论的“家族相似性”定义中的两个要素(前提11-13). 相似文献

This study investigated the influence of informational complexity and working memory capacity on problem-solving efficiency.
We examined two predictions of thesituational efficiency hypothesis, which states that the efficiency of problem solving varies as a function of situational constraints. One prediction is that
informational complexity affects problem-solving efficiency. A second prediction is that working memory capacity affects problem-solving
efficiency. Students completed a working memory task and solved abstract and concrete syllogisms. Participants solved abstract
syllogisms more accurately than concrete syllogisms and spent more time solving abstract syllogisms. Thus participants demonstrated
greater problem-solving efficiency when solving concrete syllogisms. Results indicate that there is a trade-off between problem-solving
accuracy and problem-solving time when information differs with respect to informational complexity, a phenomenon we refer
to as theefficiency paradox. Working memory capacity did not affect accuracy or efficiency. The results support the conclusion that problem-solving efficiency
is situational and a function of the complexity of information. Educational implications and directions for future research
are suggested. 相似文献

Maternal responses to infant facial expressions were examined in two socioeconomically diverse samples of South African mothers (Study I, N = 111; and Study II, N = 214; age: 17–44 years) using pupil and gaze tracking. Study I showed increased pupil response to infant distress expressions in groups recruited from private as compared to public maternity clinics, possibly reflecting underlying differences in socioeconomic status (SES) across the groups. Study II, sampling uniformly low-SES neighborhoods, found increased pupil dilation and faster orientation to expressions of infant distress, but only in the highest income group. These results are consistent with maternal physiological and attentional sensitivity to infant distress cues but challenge the universality of this sensitivity across socioeconomic diversity. 相似文献

Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two generations of British children born 30 years apart in 1970 (n = 15,676) and 2000/2 (n = 16,628) and find that both conduct and hyperactivity problems have a negative association with later vocabulary in both generations. We take advantage of rich longitudinal birth cohort data and establish that these relationships hold once family socioeconomic status and a child’s personal characteristics and earlier vocabulary acquisition are taken into account. We also find that teenagers today achieved substantively lower scores in the vocabulary assessment compared to their counterparts born 30 years earlier, and that this holds across all categories within each of the family and individual characteristics considered in this article. As vocabulary and language skills are key prerequisites for wider learning, we discuss implications the findings have for education policies. 相似文献

The present, study was conducted to determine the level of malondialdehyde (MDA) as an index of free radial induced lipid
peroxidation and antioxidant vitamins-vitamins A, vitamin C and vitamin E in 75 confirmed cases of urolithiasis. Significantly
high level of MDA (p<0.001) with significantly low levels of vitamin E (p<0.001) and vitamin A (p<0.001) with no significant
decrease in vitamin C (p>0.05) were observed in the plasma of urolithiasis cases as compared to normal controls. In conclusion,
it appears that a role of lipid peroxidation and oxidative function exists in the pathogenesis of urolithiasis. But, the exact
mechanism how this occurs remains to be elucidated. 相似文献
