Adult benefits for participants in Project CARE were compared with those of the Abecedarian Project, a closely related randomized study of early childhood educational intervention for children from low-income families who were at risk of developmental delays and school failure. CARE replicated Abecedarian's young adult treatment-related educational and vocational attainment gains. CARE data also supported the Abecedarian reduction in marijuana use. Treated individuals in both studies reported adopting a more active life style. The average age at birth of a first child, the number of children, and the proportion of teen parents were positively affected in the Abecedarian sample but not in CARE. Finding significant educational and vocational gains lasting into young adulthood in the CARE study reinforces Abecedarian young adult findings and strengthens the case for early childhood intervention for children from low-income families. 相似文献

The work practices of the professional photojournalist are currently undergoing rapid change in the digital era. New technologies, new platforms and new methods of visual storytelling are exerting a range of pressures and influences that require photojournalists to adapt and respond in different ways. The changes provoke a number of questions that are critical to the future of professional photojournalism: What are the new risks being faced by photojournalists? How are the transformations in the media economy affecting photojournalists’ employment? What does this mean for image quality? How do photojournalists think about the manipulation of images or the staging of events? Given the rise of citizen journalism, digital technology and social media, will there even be professional photojournalists in the future? This paper presents some of the results and new analysis from the first international study into the current state and future of professional photojournalism, with a specific focus on risk and on perceptions of risk among photographers. The results indicate a high degree of risk is experienced among professional photographers with a very strong correlation to the country in which they are based. 相似文献

This study tested the degree to which the uncertainty management process that emerging adults go through following an adverse event predicts their perceptions of posttraumatic growth. Participants included 215 emerging adults who had experienced an adverse life event within the past year. Overall, the results largely supported the theory of motivated information management, as uncertainty discrepancies positively predicted negative emotions about the adverse event, which in turn predicted outcome expectancies, but not efficacy assessments. Outcome expectancies were predictive of efficacy assessments, which in turn were predictive of a willingness to seek information about the event from a parent. Collectively, uncertainty management behaviors predicted posttraumatic growth and included significant indirect effects for uncertainty discrepancies through communication and target efficacy, respectively. 相似文献

Preparing student teachers to teach thoughtfully and to consider carefully the consequences of their work involves creating
opportunities for these beginning teachers to learn the skills and attitudes required for reflective practive. The case study
described here explores one model of developing reflective practice and the congruent role that the source and use of knowledge
of good teaching practice has in the process of developing the reflective practices of a post-graduate pre-service science
teacher. Of particular interest are the facilitators and barriers she sees as affecting this development.

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

Prior research reveals that differential grading patterns exist among the academic disciplines. One explanation may lie in discipline-related differences in teaching goals and beliefs about the meaning grades should convey. This study examined the effects of academic discipline and teaching goals on grading beliefs. A national sample (n = 442) of undergraduate teaching faculty provided responded to a survey measuring the importance of various teaching goals and orientations toward norm-referenced or criterion-referenced grading (Frame of Reference), and beliefs about using grades to sort and select students on the basis of achievement (Gatekeeping). Both teaching goals and academic discipline were significantly related to gatekeeping beliefs, but not to beliefs about frames of reference for grading. Higher gatekeeping scores were associated with faculty in the paradigmatic fields and those who emphasized analytic skills and time management. Lower gatekeeping scores were associated with the preparadigmatic disciplines and teaching goals of synthesis and integration and developing respect for others. Faculty who identified their primary teaching role as subject matter oriented were more gatekeeping than those who identified themselves primarily as being student/personal development oriented. 相似文献

Little research has been conducted on how students work when they are required to plan, build and evaluate artefacts in technology
rich learning environments such as those supported by tools including flow charts, Labview programming and Lego construction. In this study, activity theory was used as an analytic tool to examine the social construction
of meaning. There was a focus on the effect of teachers’ goals and the rules they enacted upon student use of the flow chart
planning tool, and the tools of the programming language Labview and Lego construction. It was found that the articulation of a teacher’s goals via rules and divisions of labour helped to
form distinct communities of learning and influenced the development of different problem solving strategies. The use of the
planning tool flow charting was associated with continuity of approach, integration of problem solutions including appreciation
of the nexus between construction and programming, and greater educational transformation. Students who flow charted defined
problems in a more holistic way and demonstrated more methodical, insightful and integrated approaches to their use of tools.
The findings have implications for teaching in design dominated learning environments. 相似文献

This paper reviews changes to the key stage 3 curriculum at a leading comprehensive school. The nature and practical concerns of the changes are described. These move beyond a fresh approach to content; they include issues about engaging students actively in learning for the future, planning around the school's distinctive ethos and expertise in ICT, and using curriculum as a vehicle for providing energy for new staff and heads of department to engage in learning leadership. Theoretical models of curriculum are examined to locate thinking at Brooke Weston CTC in a conceptual framework. The paper suggests that futuristic curriculum development resonates with some classical curriculum models that have been ignored over the past two decades of the National Curriculum. 相似文献

This paper describes a new ICT assessment tool that reduces multi‐handling of marks, comments and scores specifically where professional judgement is involved. Whereas previous ICT applications in most fields of education have focused on student learning, this tool focuses on the lecturer task of the assessment process. Unlike many ICT based assessment tools, it enables the assessor to make and record professional judgements. This tool moves the marking/recording sheet off the desk and onto the desktop (computer screen). The aim in using the tool is to reduce the unproductive busy work of marking such as adding up of marks, recording, and spell checking of comments by hand, also it allow for many different views of the information, and to increase the time spent on feedback, reflection and moderation. The tool combines features of the word processor, spreadsheet and database applications, and paper‐based marking. These features are described and discussed as working examples are presented. The paper also describes other features or possible uses of the tool, including the development and refinement of rubric‐based scales; the recording of feedback by markers about the quality of the marking key during and after marking; the ability to compare one’s marks with those of the coordinator electronically; the evaluating and analysing of results; and the printing out of many different views of the data. 相似文献
