PURPOSE: Chest radiographs (CXR) are the standard method for evaluating rib fractures in abused infants. Computed tomography (CT) is a sensitive method to detect rib fractures. The purpose of this study was to compare CT and CXR in the evaluation of rib fractures in abused infants. METHODS: This retrospective study included all 12 abused infants identified from 1999 to 2004 who had rib fractures and both CXR and CT (8 abdomen CTs, 4 chest CTs). CT exams had been performed for clinical indications, and were obtained within one day of the CXR. Studies were reviewed by two pediatric radiologists to determine the number, locations, and approximate ages of the rib fractures. A total of 225 ribs were completely (192) or partially (33) seen by CT, and the matched ribs on CXR were used for the analysis. RESULTS: The mean patient age was 2.5 months (1.2-5.6), with seven females and five males. While 131 fractures were visualized by CT, only 79 were seen by CXR (p<.001). One patient had fractures only seen by CT. There were significantly (p<.05) more early subacute (24 vs. 4), subacute (47 vs. 26), and old fractures (4 vs. 0) seen by CT than by CXR. Anterior (42 vs. 11), anterolateral (21 vs. 12), posterolateral (9 vs. 3) and posterior (39 vs. 24) fractures were better seen by CT than by CXR (p<.01). Bilateral fractures were detected more often by CT (11) than by CXR (6). CONCLUSIONS: While this study group is small, these findings suggest that CT is better than CXR in visualizing rib fractures in abused infants.  相似文献

Teachers of children aged four and five years in England (the Foundation Stage), since 2000, have been bound by the Curriculum Guidance produced by central UK Government. We were interested to learn of the responses of these teachers to this newly introduced document. We found that teachers welcomed the Foundation Stage Curriculum Guidance, not least because it recognised that there exists a valuable and separate stage in children's education. Further, the teachers were relieved that there was, within the document, the acknowledgement of the importance and value of play as integral to the educational needs of young children. The teachers indicated that the document was also beneficial in that it allowed them to return openly to what they felt to be sound Early Years practice which some had felt had been undermined by previous curriculum guidance. However, concerns remained in that not all stakeholders are yet aware of the needs of young children and of the resources necessary to meet these needs. En Angleterre, depuis 2000, les enseignants des enfants de quatre et cinq ans (phase dite de 'fondation') doivent se conformer à la Curriculum Guidance (Lignes directrices des programmes scolaires) produite par le gouvernement central du Royaume-Uni. Nous souhaitions connaître les réactions de ces enseignants face à ce nouveau document. Nous avons constaté que les enseignants accueillent favorablement la Foundation Stage Curriculum Guidance tant elle reconnaît l'existence d'une phase utile et distincte d'assimilation chez les enfants. En outre, les enseignants ont été soulagés de constater que la document reconnaît l'importance et l'utilité du jeu comme faisant partie intégrante des besoins éducatifs des jeunes écoliers. Ils ont également fait savoir qu'ils trouvent ce document utile dans la mesure où il leur permet de revenir ouvertement à des pratiques qu'ils considèrent comme étant saines pendant les premières années scolaires des enfants et qui, selon certains, avaient été amoindries par les lignes directrices des programmes scolaires précédents. Ils s'avèrent néanmoins toujours préoccupés du fait que toutes les parties prenantes ne sont pas encore conscientes des besoins des jeunes enfants et des ressources nécessaires pour les satisfaire. Desde el año 2000, en Inglaterra, los profesores de niños de la edad de 4 y 5 años (la Etapa de Fundación) han tenido que conformar con las reglas de curriculum introducidas por el gobierno central del Reino Unido. Tuvimos interes de enterarnos de las respuestas de aquellos profesores a ese documento nuevo. Encontramos que los profesores estan de acuerdo con la 'Guía de Curriculum de la Etapa de Fundación', por lo menos porque reconoció que existe una etapa válida y aparte en la educación de niños. Además estuvieron contentos que el documento reconició la importancia y validez de juegos infántiles imprescindible en el desarrollo del niño. Los profesores indicáron que el documento fue beneficioso también porque les permitió volver abiertamente a lo que sentieron que fueron 'prácticas sanas' de los años primeros que algunos de ellos pensaron que habían estado desacreditadas por las 'Guías de Curriculum' previas. No obstante quedan preocupaciónes que algunos interesados todavía no estan enterados de lo que los niños necesitan y los recursos que hacen falta.  相似文献

Calibration of an item bank for computer adaptive testing requires substantial resources. In this study, we investigated whether the efficiency of calibration under the Rasch model could be enhanced by improving the match between item difficulty and student ability. We introduced targeted multistage calibration designs, a design type that considers ability‐related background variables and performance for assigning students to suitable items. Furthermore, we investigated whether uncertainty about item difficulty could impair the assembling of efficient designs. The results indicated that targeted multistage calibration designs were more efficient than ordinary targeted designs under optimal conditions. Limited knowledge about item difficulty reduced the efficiency of one of the two investigated targeted multistage calibration designs, whereas targeted designs were more robust.  相似文献

This study investigated college student perceptions of the (in)appropriateness of instructor disclosures and perceived functions of instructor disclosures. An interpretive analysis of 35 college students identified that family relationships, life experiences and background, and everyday talk and activities were forms of appropriate disclosures; whereas, intimate relationship details, personal problems, personal opinions, and drinking behavior were considered inappropriate topics for instructors to disclose. In terms of the function of instructor disclosures, students perceived that these disclosures worked to humanize instructors, make instructors approachable, and create affect for instructors and courses. Implications and future research are also discussed.  相似文献

Abstract

Teachers regularly communicate with families, yet few candidates are well-prepared for this professional activity. This gap can hinder family–school partnership and pupils’ success. Given that candidates’ opportunities to learn about family engagement (FE) depends on the decisions and values of individual teacher educators, we illustrate how FE can be integrated into an existing educator preparation programme. Specifically, we describe how to design and use simulated parent–teacher conferences (PTCs) to: foster candidates’ conference communication skills; assess their understanding of content knowledge and their ability to plan instruction. Specifically, we designed two simulation tasks that required candidates’ to analyse and respond to a given student assessment profile and then share their interpretation of the information in ways that developed parent–teacher partnership. Modelled after simulation-based medical education, we describe three steps teacher educators can take to integrate simulated PTCs into their existing curriculum. To illustrate how and why simulations impact professional readiness, we also describe the advantages, sequence and psychological processes of simulation training. A sample of candidate profiles across the two tasks are shared to illustrate what candidates take away from their experiences and the kinds of findings faculty may encounter when integrating simulation pedagogy.  相似文献

This paper focuses on academic and welfare support for students in higher education, and specifically what makes that support effective. It draws on data from a research project which aimed to explore networks of support for disabled and non‐disabled students. Part of the research focused on the nature and sources of support that were identified as important by students, as well as the kinds of support that were available within the higher education institution (HEI). What emerged as of particular interest was the question, ‘What do we mean by support?’ Drawing mainly on the voices and experiences of the students, perceptions of support were explored and the effects of support on the students’ experience of higher education were considered. Through a focus on more generic support structures as well as support which was specific to individual (disabled) students, the research aimed to understand ‘support’ and its importance from the student perspective.  相似文献
