Legacy for Children™ (Legacy) is an evidence-based program focused on promoting sensitive, responsive parenting for socioeconomically disadvantaged families. Legacy has recently been culturally and linguistically adapted for Spanish-monolingual Latino families and is being piloted in partnership with an early childhood education program. We conducted a mixed methods study to identify barriers and facilitators to engagement, using program monitoring data sources from both participant and group leader perspectives. We conducted qualitative analyses of open-ended data to identify distinct barriers (e.g., employment challenges, health-related challenges and appointments) and facilitators (e.g., other mothers in group, interest in program topics) to engagement that emerged across English and Spanish language curriculum versions; curriculum-specific barriers and facilitators were also documented. We interpret these findings in light of quantitative data on measures of engagement, showing that participants in the Spanish curriculum evidenced comparable levels of parent–group leader relationship quality relative to the English group, and higher levels of parent's group support/connectedness and overall satisfaction. These results offer promising considerations for optimizing families’ engagement in parenting programs in the context of early care and education settings. 相似文献

Wigner found unreasonable the "effectiveness of mathematics in the natural sciences". But if the mathematics we use to describe nature is simply a carefully coded expression of our experience then its effectiveness is quite reasonable. Its effectiveness is built into its design. We consider group theory, the logic of symmetry. We examine the premise that symmetry is identity; that group theory encodes our experience of identification. To decide whether group theory describes the world in such an elemental way we catalogue the detailed correspondence between elements of the physical world and elements of the formalism. Providing an unequivocal match between concept and mathematical statement completes the case. It makes effectiveness appear reasonable. The case that symmetry is identity is a strong one but it is not complete. The further validation required suggests that unexpected entities might be describable by the irreducible representations of group theory. 相似文献

Over repeated exposure to particular visual search displays, subjects are able to implicitly extract regularities that then make search more efficient-a phenomenon known as contextual cueing. Here we explore how the learning involved in contextual cueing is formed, maintained, and updated over experience. During an initial training phase, a group of signal first subjects searched through a series of predictive displays (where distractor locations were perfectly correlated with the target location), followed with no overt break by a series of unpredictive displays (where repeated contexts were uncorrelated with target locations). A second noise first group of subjects encountered the unpredictive displays followed by the predictive displays. Despite the fact that both groups had the same overall exposure to signal and noise, only the signal first group demonstrated subsequent contextual cueing. This primacy effect indicates that initial experience can result in hypotheses about regularities in displays-or the lack thereof-which then become resistant to updating. The absence of regularities in early stages of training even blocked observers from learning predictive regularities later on. 相似文献

Precipitating Circumstances of Suicide among Active Duty U.S. Army Personnel Versus U.S. Civilians, 2005–2010 下载免费PDF全文

To help understand suicide among soldiers, we compared suicide events between active duty U.S. Army versus civilian decedents to identify differences and inform military prevention efforts. We linked 141 Army suicide records from 2005 to 2010 to National Violent Death Reporting System (NVDRS) data. We described the decedents’ military background and compared their precipitators of death captured in NVDRS to those of demographically matched civilian suicide decedents. Both groups commonly had mental health and intimate partner precipitating circumstances, but soldier decedents less commonly disclosed suicide intent. 相似文献

The purpose of this study is to investigate the effects of a relational intervention (the Getting Ready intervention) on parenting behaviors supporting the parent–infant relationship for families enrolled in Early Head Start home‐based programming. Two‐hundred thirty‐four parents and their children participated in the randomized study, with 42% of parents reporting education of less than a high‐school diploma. Brief, semistructured parent–child interaction tasks were videotaped every 4 months over a16‐month intervention period. Observational codes of parent–infant relationship behaviors included quality of three parental behaviors: warmth and sensitivity, support for learning, and encouragement of autonomy; two appropriateness indicators: support for learning and guidance/directives; and one amount indicator: constructive behaviors. Parents who participated in the Getting Ready intervention demonstrated higher quality interactions with their children that included enhanced quality of warmth and sensitivity, and support for their children's autonomy than did parents in the control group. They also were more likely to use appropriate directives with their children and more likely to demonstrate appropriate supports for their young children's learning. Results indicate an added value of the Getting Ready intervention for Early Head Start home‐based programming for families of infants and toddlers. 相似文献

We used nonconcurrent and concurrent multiple baseline designs to evaluate the extent to which error correction with response repetition (RR) produced acquisition of math facts and correct math computation for four individuals diagnosed with intellectual disabilities. The results show that RR increased correct responding on (i) targeted math problems for three of four participants and (ii) math problems presented in alternative formats for two of two participants. The results are consistent with prior studies that used RR to increase correct sight‐word reading for individuals with intellectual disabilities. The findings are discussed in terms of how RR might be implemented in typical classroom settings. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Prospecting is a fundamental step in the personal selling process. However, a wide variety of prospecting approaches exists among sales organizations and there is substantial disagreement in the terms used to describe prospecting elements and relationships. This article presents a working model that identifies and defines those elements and clearly demonstrates the strategic relationships among them. Insights and implications for managers are presented, along with suggestions for analyzing and modifying existing prospect-development programs. 相似文献
