Parental interactions with Latino infants: variation by country of origin and English proficiency 总被引:2,自引:0,他引:2
This study examined variation in mother-infant interactions, father engagement, and infant cognition as a function of country of origin, socioeconomic status, and English language proficiency in a national sample of Latino infants (age 9 months) born in the United States and living with both biological parents (N=1,099). Differences between Mexican-American infants, who had lower mother-infant interaction scores and less father physical play than did the other Latino infants, were associated with differences in acculturation (both parents' English proficiency). Indicators of acculturation and paternal reports of happiness with partner were associated with paternal engagement. Indicators of acculturation were also related to mother-infant interactions. Infant cognitive scores were associated with maternal interaction but not father engagement, and maternal but not paternal mental health. 相似文献

Previous research studies examining the effects of spelling and reading interventions on the spelling outcomes of students with learning disabilities (LD) are synthesized. An extensive search of the professional literature between 1995 and 2003 yielded a total of 19 intervention studies that provided spelling and reading interventions to students with LD and measured spelling outcomes. Findings revealed that spelling outcomes were consistently improved following spelling interventions that included explicit instruction with multiple practice opportunities and immediate corrective feedback after the word was misspelled. Furthermore, evidence from spelling interventions that employed assistive technology aimed at spelling in written compositions indicated positive effects on spelling outcomes. 相似文献

The relative effects of group size on reading progress of older students with reading difficulties 总被引:1,自引:0,他引:1
Vaughn S Wanzek J Wexler J Barth A Cirino PT Fletcher J Romain M Denton CA Roberts G Francis D 《Reading and writing》2010,23(8):931-956
This study reports findings on the relative effects from a yearlong secondary intervention contrasting large-group, small-group,
and school-provided interventions emphasizing word study, vocabulary development, fluency, and comprehension with seventh-
and eighth-graders with reading difficulties. Findings indicate that few statistically significant results or clinically significant
gains were associated with group size or intervention. Findings also indicate that a significant acceleration of reading outcomes
for seventh- and eighth-graders from high-poverty schools is unlikely to result from a 50 min daily class. Instead, the findings
indicate, achieving this outcome will require more comprehensive models including more extensive intervention (e.g., more
time, even smaller groups), interventions that are longer in duration (multiple years), and interventions that vary in emphasis
based on specific students’ needs (e.g., increased focus on comprehension or word study). 相似文献

Abstract This study investigated the effects of exercise on blood cholesterol and correlated those effects with estimates of body fat through experiments with 45 albino weanling rats (15 litter mate trios). The rats were confined to individual cages in a temperature-controlled room and fed a stock diet until they were 11 weeks old. At this time the trios were divided. Group A was continued on a stock diet and exercised for an hour in the morning and an hour in the afternoon by forced swimming. Group B was subjected to the same exercise but a portion of the stock diet was replaced with powdered whole milk, so that 30 percent of the caloric intake was derived from the whole milk supplement. Group C was fed the stock diet but activity was restricted. After 15 weeks blood samples were taken, the animals sacrificed, and the heart and adrenals weighed. The specific gravity of the carcass was also determined. Exercise resulted in a statistically significant decrease in total and free blood serum cholesterol concentration. These animals were also leaner and had larger hearts and adrenal glands. Serum cholesterol was negatively related to carcass specific gravity. The milk supplement had no significant effect on any of these measures. Several possible explanations for the effects of exercise on blood cholesterol are discussed. 相似文献

The Toxicology and Environmental Health Information Program (TEHIP) of the National Library of Medicine (NLM) works to organize and provide access to a wide range of environmental health and toxicology resources. In recent years, the demand for, and availability of, information on health issues related to natural and man-made emergencies and disasters has increased. Recognizing that access to information is essential in disaster preparedness, a new focus of NLM's 2006-2016 Long Range Plan calls for the establishment of a Disaster Information Management Research Center (DIMRC) that will aid in collecting, disseminating, and sharing information related to health and disasters. This paper introduces several of TEHIP's resources for emergency/disaster preparedness and response, such as the Radiation Event Medical Management Web site (REMM) and the Wireless Information System for Emergency Responders (WISER) . Several of NLM's other disaster preparedness and response resources will also be reviewed. 相似文献

During a dual-center study on obese and normal weight children and adolescents, focusing on glucose metabolism, we observed a marked difference in glucose results (N = 16,840) between the two sites, Salzburg, Austria and Uppsala, Sweden (P < 0.001). After excluding differences in patient characteristics between the two populations as cause of this finding, we investigated other preanalytic influences. Finally, only the tubes used for blood collection at the two sites were left to evaluate. While the Vacuette FC-Mix tube (Greiner Bio-One, Kremsmünster, Austria) was used in Uppsala, in Salzburg blood collections were performed with a lithium heparin tube (LH-Monovette, Sarstedt, Germany). To prove our hypothesis, we collected two blood samples in either of these tubes from 51 children (Salzburg N = 27, Uppsala N = 24) and compared the measured glucose results. Indeed, we found the suspected bias and calculated a correction formula, which significantly diminished the differences of glucose results between the two sites (P = 0.023). Our finding is in line with those of other studies and although this issue should be widely known, we feel that it is widely neglected, especially when comparing glucose concentrations across Europe, using large databases without any information on preanalytic sample handling. 相似文献

Century 21 International, like so many sales organizations, suffered lower productivity and higher attrition from new sales associates than they judged to be acceptable. The answer, Century 21 executives believed, was to develop a twenty-one module, multimedia training program. An external consultant urged them to study the situation prior to committing to any one solution. The results were clear. While new sales people certainly needed to have their field skills “buffed” after going through pre-licensing training and entering the office, that was not their most critical need. Far more important was an in-office support system, someone to tell them how to think through inevitable rejections, how to approach recurring challenges, how to maintain confidence even when sales do not occur, how to prospect portions of the community and how to integrate into the real estate community. The data revealed the need for a solution system comprised of training, incentives, performance support materials, the introduction of a new position, a coach, into each office, and a selection method for that coach. This article describes the front end study, the program, and some of its results in real estate offices across the United States. 相似文献
