A randomized controlled trial was used to examine the impact of an attachment‐based, teacher–child, dyadic intervention (Banking Time) to improve children's externalizing behavior. Participants included 183 teachers and 470 preschool children (3–4 years of age). Classrooms were randomly assigned to Banking Time, child time, or business as usual (BAU). Sparse evidence was found for main effects on child behavior. Teachers in Banking Time demonstrated lower negativity and fewer positive interactions with children compared to BAU teachers at post assessment. The impacts of Banking Time and child time on reductions of parent‐ and teacher‐reported externalizing behavior were greater when teachers evidenced higher‐quality, classroom‐level, teacher–child interactions at baseline. An opposite moderating effect was found for children's positive engagement with teachers. 相似文献

Associations between relational aggression and mutual, dyadic friendships during early childhood were assessed in the context of a year-long, short-term longitudinal study. Children's mutual friendships were determined via sociometric ratings and their relationally aggressive behavior among peers was assessed via naturalistic, free play observations. Generally, children who were more relationally aggressive had more mutual friends, although this relation differed by gender and time of assessment. Future work should include measures of friendship quality and investigate the role of relational aggression within friendship dyads. 相似文献

We studied the effect of psyching-up on one-repetition maximum (1-RM) performance and salivary cortisol responses during the squat exercise. Ten men (age 21.6+/-1.4 years; mean+/-s) and ten women (age 22.4+/-2.8 years) with weight training experience of 4.5+/-2.0 years participated in this study. One-repetition maximum squats were performed on a Smith machine during each of two different intervention conditions that were counterbalanced and consisted of a free choice psych-up and a cognitive distraction. Saliva samples were obtained at the beginning of each test session and immediately after the final 1-RM attempt. No significant difference in 1-RM was identified between psyching-up (104+/-50 kg) and cognitive distraction (106+/-52 kg). Performing a 1-RM in the squat exercise significantly increased salivary cortisol concentrations during both conditions (P<0.05). There was no significant difference in salivary cortisol responses between conditions. These results suggest that psyching-up does not increase 1-RM performance during the squat exercise in strength-trained individuals. 相似文献

Parents' Socialization of Children's Injury Prevention: Description and Some Initial Parameters 总被引:2,自引:0,他引:2
In a year-long participant observation study of remediative action following actual injury, 61 8- and 9-year-old children and their 27-46-year-old mothers wrote records and reported on more than 1,000 minor injuries in branching biweekly interviews. Mothers reported that 80.1% of injuries received no parent-initiated remediation, 14% received only a lecture, and less than 3% of injuries were followed by parental action. Children reported that 96.1% of their injuries were followed by no remediative action and recalled lectures after only 1.2% of injuries. Remediative action was related to type of child activity (e.g., unstructured play was followed by remediation more often than more purposive behavior) and to mother's affect (e.g., anger) and beliefs (e.g., that injury was the child's fault or due to rule violation). The parameters that influenced remediative consequences, and thus that may influence future injury, are discussed. 相似文献

Successful recruiting for collegiate track & field athletes has become a more competitive and essential component of coaching. This study aims to determine the relationship between race performances of distance runners at the United States high school and National Collegiate Athletic Association (NCAA) levels. Conditional inference classification tree models were built and analysed to predict the probability that runners would qualify for the NCAA Division I National Cross Country Meet and/or the East or West NCAA Division I Outdoor Track & Field Preliminary Round based on their high school race times in the 800 m, 1600 m, and 3200 m. Prediction accuracies of the classification trees ranged from 60.0 to 76.6 percent. The models produced the most reliable estimates for predicting qualifiers in cross country, the 1500 m, and the 800 m for females and cross country, the 5000 m, and the 800 m for males. NCAA track & field coaches can use the results from this study as a guideline for recruiting decisions. Additionally, future studies can apply the methodological foundations of this research to predicting race performances set at different metrics, such as national meets in other countries or Olympic qualifications, from previous race data. 相似文献

Multilingual information retrieval is generally understood to mean the retrieval of relevant information in multiple target
languages in response to a user query in a single source language. In a multilingual federated search environment, different
information sources contain documents in different languages. A general search strategy in multilingual federated search environments
is to translate the user query to each language of the information sources and run a monolingual search in each information
source. It is then necessary to obtain a single ranked document list by merging the individual ranked lists from the information
sources that are in different languages. This is known as the results merging problem for multilingual information retrieval.
Previous research has shown that the simple approach of normalizing source-specific document scores is not effective. On the
other side, a more effective merging method was proposed to download and translate all retrieved documents into the source
language and generate the final ranked list by running a monolingual search in the search client. The latter method is more
effective but is associated with a large amount of online communication and computation costs. This paper proposes an effective
and efficient approach for the results merging task of multilingual ranked lists. Particularly, it downloads only a small
number of documents from the individual ranked lists of each user query to calculate comparable document scores by utilizing
both the query-based translation method and the document-based translation method. Then, query-specific and source-specific
transformation models can be trained for individual ranked lists by using the information of these downloaded documents. These
transformation models are used to estimate comparable document scores for all retrieved documents and thus the documents can
be sorted into a final ranked list. This merging approach is efficient as only a subset of the retrieved documents are downloaded
and translated online. Furthermore, an extensive set of experiments on the Cross-Language Evaluation Forum (CLEF) () data has demonstrated the effectiveness of the query-specific and source-specific results merging algorithm against other
alternatives. The new research in this paper proposes different variants of the query-specific and source-specific results
merging algorithm with different transformation models. This paper also provides thorough experimental results as well as
detailed analysis. All of the work substantially extends the preliminary research in (Si and Callan, in: Peters (ed.) Results
of the cross-language evaluation forum-CLEF 2005, 2005).

ABSTRACTCataloging digitized continuing resources is a challenging task for many libraries because of their complex cataloging rules and characteristics of format. As libraries provide their digitized content and catalog records in shared environments, like HathiTrust, and use them as an access point, libraries also have to work with holdings and item records created by each contributing institution's local practice. This article discusses common challenges imposed on libraries when creating and providing access to digitized continuing resources available in a shared environment, stresses the importance of having shareable holdings and items records, and suggests possible ways to work with those challenges. 相似文献

Prompt strategies have been used to increase the compliance of preschool-aged children to teacher directives. This paper describes two experiments conducted to determine if classroom teachers could learn to use the LtM prompt hierarchy and if child compliance would increase in response to teacher behavior. This study builds on the current literature base by using prompting, specifically LtM with the additional requirement of teacher-child proximity and teacher-child eye level prior to beginning the prompt sequence, which is consistent with recommended practice in early childhood (Copple and Bredekamp, Developmentally appropriate practice in early childhood programs (revised edition), National Association for the Education of Young Children, Washington, DC, 2009). The participants consisted of 6 preschool teachers, with varying levels of education and experience, across 2 different early childhood classrooms. Teacher prompts and children's completion of teacher directives were measured during free choice center time. Results were consistent with previous research in that compliance to teacher directives increased in preschool children with the implementation of the LtM. 相似文献

AbstractAcademic self-efficacy, the belief that one can achieve desired academic goals plays an important role in learning. This study aimed to determine the extent to which academic self-efficacy mediates relationships between students’ perceptions of feedback and their academic attainment. An opportunity sample of 232 students (123 female) in their first year of higher education reported their academic self-efficacy and evaluated their assessment experience, including the perceived quantity and quality of feedback and the extent to which this feedback elicited an active response. Positive associations were observed between academic attainment and students’ confidence that they could achieve their desired grades and adopt appropriate study behaviours. A negative association was identified between attainment and confidence to talk about their studies. Attainment was not related to the perceived quantity or quality of feedback, but did bear a significant association with the reported use to which feedback was put. Positive associations were generally identified between academic self-efficacy and perceptions of feedback. Path models revealed that inter-relationships were best represented by a model wherein academic self-efficacy mediated links between students’ perceptions of feedback and academic attainment. The findings highlight the need to incorporate characteristics of the individual into an understanding of student engagement with feedback. 相似文献
