The present study identifies characteristics of individuals and work settings that influence Asian international faculty members’ intentions to continue their employment in US research universities. Given the demand for researchers in science, technology, engineering and mathematics fields (STEM), the higher rate of turnover among untenured faculty, and the replacement costs associated with turnover in STEM, the sample is limited to assistant professors employed in these areas. Multinomial regression analyses are conducted to identify variables that “pull” and “push” uncertain faculty toward intentions stay and leave their current institutions. The results suggest that faculty who are more satisfied with time available for research and those who express stronger organizational commitment are more likely to say they will stay. Those dissatisfied with the fairness of work evaluations and believe tenure decisions are not merit-based, are more likely to say they will leave. 相似文献

The objective of this study is to determine the prevalence and correlates of obesity among youth investigated for maltreatment in the United States. Participants were drawn from the National Survey of Child and Adolescent Well-Being II, a national probability study of 5,873 children aged birth to 17 years under investigation for maltreatment in 2008. From child weight reported by caregivers, we estimated obesity (weight-for-age ≥95th percentile) prevalence among children aged 2 through 17 (n = 2,948). Sex-specific logistic regression models by developmental age were used to identify obesity risk factors, including child age, race/ethnicity, and maltreatment type. Obesity prevalence was 25.4% and was higher among boys than girls (30.0% vs. 20.8%). African American adolescent boys had a lower risk for obesity than white boys (OR = 0.28, 95% CI [0.08, 0.94]). Compared with girls aged 2–5 with a neglect allegation, girls with a sexual abuse allegation were at greater risk for obesity (OR = 3.54, 95% CI [1.01, 12.41]). Compared with adolescent boys with a neglect allegation, boys with a physical abuse allegation had a lower risk for obesity (OR = 0.24, 95% CI [0.06, 0.99]). Adolescent girls with a prior family history of investigation were at greater risk for obesity than those without a history of investigation (OR = 3.97, 95% CI [1.58, 10.02]). Youth investigated for maltreatment have high obesity rates compared with national peers. Opportunities to modify and evaluate related child welfare policies and health care practices should be pursued. 相似文献

In two experiments undergraduate students were shown maps with features located either along an edge or within the interior of the map. Next, participants were asked to read a related text. Thereafter, they were asked to recall as much of the text information as possible and to reconstruct the map. In both experiments, the results consistently showed that students recall significantly more information when features are located along the edges of the maps. These findings will help give teachers and designers of classroom displays a better understanding of how to create maps that will facilitate the recall of related information.

In this qualitative study of mathematical discourse between elementary teachers, we examined linguistic invention and semantic warrant production as participants made successive attempts to communicate mathematical ideas. Linguistic invention is a creative practice of describing mathematics in terms of personal experience. We introduce semantic warrant production, which emerged as part of our analysis of substantial arguments produced by teachers learning mathematics. Participants engaged in linguistic invention and semantic warrant production to convince themselves and others of the validity of their mathematical inferences about a graph of rate of change versus time. Personal experiences that are taken-as-shared in a learning community can support accurate mathematical inference if connections between conventional language, common experiences, and mathematical representations are made explicit by learners. 相似文献

Positive Transitions for Student Athletes is a program designed to address the psychosocial and career‐related issues surrounding the inevitable sport retirement transition faced by the majority of collegiate athletes. A rationale for the development of sport retirement programs is provided, as is the Positive Transitions program and outcome data. 相似文献

This study investigated normative precision in 14 preschool tests representing four domains: cognitive, language, adaptive behavior, and early academic skills. The purpose was to explore the consequences of using tests with more‐ vs. less‐precise age norms to identify disabilities in preschool children. As expected, on tests with more precise norms, standard scores associated with the same raw score shifted gradually across age groups. On the other hand, tests with less precise norms showed more dramatic standard score shifts across age groups. Examination of the degree of shift found in each test indicated that many preschool tests have norm tables that are potentially problematic for diagnosing disabilities, particularly for children near norm group cut‐off ages. On high stakes tests, an optimal span is one to three months. This standard can be achieved by using interpolation and/or increasing the size of norming samples at the preschool level. © 1999 John Wiley & Sons, Inc. 相似文献

Teacher-conducted assessments of practical skills are a compulsory component of GCSE examinations in science in England and Wales. The paper presents some of the findings of a research project that investigated this aspect of a science teacher's work. The project was concerned principally with the ways in which science teachers interpreted and operationalised the policy decision of central government and examination boards that teachers assume responsibility for the internal assessment of the practical competence of pupils aged 14–16 preparing for GCSE examinations in science.
