Does Fidelity of Implementation Account for Changes in Teacher–Child Interactions in a Randomized Controlled Trial of Banking Time?

This study examined fidelity of implementation in a randomized trial of Banking Time, a classroom-based intervention intended to improve children's behavior, specifically for those at risk for developing externalizing behavior problems, through improving the quality of teacher–child interactions. The study sample comes from a randomized controlled trial that took place over three years and included 183 teachers and 470 preschool children recruited across three sites. Results exploring fidelity of implementation indicated that Banking Time practices were present across treatment and nontreatment groups. In addition, the presence of more Positive Banking Time Practices accounted for improvements in teacher–child interactions while Restricted Banking Time Practices showed inconsistent patterns, relating both to positive and negative teacher–child interactions. Further, random assignment to Banking Time resulted in the presence of more Positive Banking Time Practices and fewer Restricted Banking Time Practices, which accounted for the improved teacher–child interactions. Thus, findings point to the critical need to better account for intervention fidelity across conditions in randomized trials, allowing for better understanding of the mechanism through which interventions lead to intended outcomes.  相似文献   

The innovative performance of in-house and contracted R&D in terms of patents and utility models     

Pilar Beneito 《Research Policy》2006,35(4):502-517

The standard empirical framework for analysing the R&D-patents relationship is widened both by examining the different role of in-house and contracted R&D in the innovative performance of firms, and by considering patents and utility models counts as measures of innovation output. Patents and utility models are considered to approximate for significant and incremental innovations, respectively. Applying count data econometrics to a panel data set of Spanish manufacturing firms surveyed in the period 1990-1996, a transcendental production function is estimated, which allows for non-constant elasticities of the R&D inputs. The results indicate that significant innovations are mainly gestated in-house, whereas contracted R&D seems more orientated towards innovations of incremental nature.  相似文献

Individual Differences in Childhood Behavior Disorders Associated With Epigenetic Modulation of the Cortisol Receptor Gene          下载免费PDF全文

Behavioral/emotional difficulties in children are the first sign of mental health problems. These problems are however, heterogeneous. A domain that may identify homogenous subgroups is hypothalamic–pituitary–adrenal function. This study tested whether epigenetic regulation of glucocorticoid receptor gene could explain the co‐occurrence of anxiety problems in children with behavior problems. Four‐ to 16‐year‐old clinically referred children (N = 241) were measured for psychiatric symptoms, methylation of target CpG sites in blood or saliva, and morning cortisol levels in those who gave blood. Increased methylation of promoter 1F CpG sites was associated with higher vulnerability to co‐occurring internalizing symptoms and morning cortisol. The results support increasing optimism that epigenetic regulation of key neuroendocrine systems might help explain hitherto unfathomable individual differences in susceptibility to psychiatric symptom profiles.  相似文献

Inducing chemotactic and haptotactic cues in microfluidic devices for three-dimensional in vitro assays     

O. Moreno-Arotzena  G. Mendoza  M. Cóndor  T. Rüberg  J. M. García-Aznar 《Biomicrofluidics》2014,8(6)

Microfluidic devices allow for the production of physiologically relevant cellular microenvironments by including biomimetic hydrogels and generating controlled chemical gradients. During transport, the biomolecules interact in distinct ways with the fibrillar networks: as purely diffusive factors in the soluble fluid or bound to the matrix proteins. These two main mechanisms may regulate distinct cell responses in order to guide their directional migration: caused by the substrate-bound chemoattractant gradient (haptotaxis) or by the gradient established within the soluble fluid (chemotaxis). In this work 3D diffusion experiments, in combination with ELISA assays, are performed using microfluidic platforms in order to quantify the distribution of PDGF-BB and TGF-β₁ across collagen and fibrin gels. Furthermore, to gain a deeper understanding of the fundamental processes, the experiments are reproduced by computer simulations based on a reaction-diffusion transport model. This model yields an accurate prediction of the experimental results, confirming that diffusion and binding phenomena are established within the microdevice.  相似文献   

Recruiting older adults as participants in applied social research: Applying and evaluating approaches from clinical studies     

Joyce Weil  Angela Nancy Mendoza  Erin McGavin 《Educational gerontology》2017,43(12):662-673

While issues of recruiting older persons in clinical trials are well known, efficacious strategies in the recruitment process in applied social research are less explored. As more research becomes community-based, it is useful to see, if effective clinical-trial recruitment strategies can be applied to social and applied research studies. The goal of this article is to examine clinical recruitment strategies used with older adults (e.g. print and electronic advertising, referrals, and community-partnered approaches) in applied social research studies and to illustrate issues arising from the use of each recruitment approach with older adults in real-life settings. Experiences from four community-based, social research studies are included to show how some of the most successful clinical recruitment strategies fare in social gerontological studies. Specific guidelines are provided about how recruitment strategies can aid in future study planning and improved recruitment of older participants in social research.  相似文献   

Becoming a tutor: student scaffolding in a game-based classroom     

Natalia Monjelat  Laura Méndez  Pilar Lacasa 《Technology, Pedagogy and Education》2017,26(3):265-282

Student interaction in school contexts is a topic that has been researched from many different perspectives. However, the role of students as tutors scaffolding other peers is not normally addressed, since studies are usually focused on the teacher. Moreover, considering the many technologies that can support students’ work nowadays, studies describing specific practices are still needed in order to understand the many possibilities and constraints that can emerge from the use of these tools in the field of education. This exploratory case study aims to extend research on scaffolding between students, presenting data from an ethnographic study where a commercial video game was introduced as part of the curricular activities. Analytically, the scaffolding metaphor is the departing point to describe in detail how the scaffolding process took place, focusing on its purposes and on the role of students as tutors. Our findings reveal how students offered mostly procedural scaffoldings, performing tutor functions such as highlighting relevant features, reducing levels of freedom or controlling the frustration. Results highlight that students can perform scaffolds, and this should be considered as part of the classroom design, making this process visible. Moreover, specific features of the video game enhanced these interactions, which should also be considered when designing game learning environments in the future.  相似文献
