Prematurity may cause hippocampal compromise. Therefore, hippocampus‐dependent memory processes (recollection‐based retrieval) may be more impaired than hippocampus‐independent processes (familiarity‐based retrieval). The memory of 18 children born preterm with reduced hippocampal volumes, without neonatal complications (weeks of gestation < 34, weight < 1,600 g), and 15 controls (8–10 years) was tested using an item recognition task. While groups were equal in memory performance, dissociation was found: The event‐related potential (ERP) correlate of familiarity was intact in the preterm group, whereas the correlate of recollection was attenuated. A follow‐up experiment ruled out that this was due to general cognitive deficits. Furthermore, gestational age correlated with the ERP index of recollection. Thus, recognition memory in preterm children may be characterized by a compensation of attenuated recollection by familiarity.  相似文献   

Comparing effects and side effects of different school inspection systems across Europe

In this article, different inspection models are compared in terms of their impact on school improvement and the mechanisms each of these models generates to have such an impact. Our theoretical framework was drawn from the programme theories of six countries’ school inspection systems (i.e. the Netherlands, England, Sweden, Ireland, the province of Styria in Austria and the Czech Republic). We describe how inspection models differ in the scheduling and frequency of visits (using a differentiated or cyclical approach), the evaluation of process and/or output standards, and the consequences of visits, and how these models lead to school improvement through the setting of expectations, the use of performance feedback and actions of the school's stakeholders. These assumptions were tested by means of a survey of principals in primary and secondary schools in these countries (n?=?2239). The data analysis followed a three-step approach: (1) confirmatory factor analyses, (2) path modelling and (3) fitting of multiple-indicator multiple-cause models. The results indicate that Inspectorates of Education that use a differentiated model (in addition to regular visits), in which they evaluate both educational practices and outcomes of schools and publicly report inspection findings of individual schools, are the most effective. These changes seem to be mediated by improvements in the schools’ self-evaluations and the schools' stakeholders’ awareness of the findings in the public inspection reports. However, differentiated inspections also lead to unintended consequences as principals report on narrowing the curriculum and on discouraging teachers from experimenting with new teaching methods.  相似文献   

A dynamic auction for multi-object procurement under a hard budget constraint     

Ludwig Ensthaler  Thomas Giebe 《Research Policy》2014

This contribution revisits the problem of allocating R&D subsidies by government agencies. Typically, the applicants’ financial constraints are private information. The literature has recommended the use of auctions in order to reduce information rents and thus improve the efficiency of how scarce public funds are allocated. We propose a new open clock auction for this procurement problem. This auction is strategically simple, as it exhibits truthtelling in dominant strategies and satisfies ex-post rationality, while observing the budget constraint. We test the auction in Monte-Carlo simulation and discuss its applicability and limitations. Moreover, we highlight connections to recent advances in computer science.  相似文献   

Mathe mit der Matte – Verkörperlichtes Training basisnumerischer Kompetenzen     

Tanja Link  Eva Johanna Schwarz  Stefan Huber  Dr. Ursula Fischer  Prof. Dr. Hans-Christoph Nuerk  Prof. Dr. Ulrike Cress  Prof. Dr. Korbinian Moeller 《Zeitschrift für Erziehungswissenschaft》2014,17(2):257-277

Basic numerical representations are seen as the building block for the successful development of more complex numerical and arithmetic competencies. Extending previous studies focusing on improving basic numerical representations by means of embodied training schemes, the current study focused on an embodied training of children’s place-value understanding. In this vein, 49 secondgraders were trained on solving a number line estimation task by stepping on different fields of a dance mat allowing for separate estimations of tens and units with more effort needed to step on the tens. In a partially randomized cross-over design, two control conditions were used to controll for training effects caused exclusively by the numerical content trained or the use of the dance mat. Interestingly, results revealed specific training effects after both the embodied and the control conditions. However, training effects were significantly more pronounced after the embodied training, thereby providing further evidence for the benefit of an embodied training of the place-value structure of the Arabic number system.  相似文献

Clinical medical librarian: the last unicorn?   总被引：1，自引：0，他引：1  

J M Demas  L T Ludwig 《Bulletin of the Medical Library Association》1991,79(1):17-27

In the information age of the 1990s, the clinical medical librarian (CML) concept, like many other personalized library services, is often criticized as being too labor-intensive and expensive; others praise its advantages. To determine the attitudes of medical school library directors and clinical department heads toward implementation and feasibility of a CML program, forty randomly selected medical schools were surveyed. A double-blind procedure was used to sample department heads in internal medicine, pediatrics, and surgery, as well as health sciences library directors identified by the Association of Academic Health Sciences Library Directors (AAHSLD) annual statistics. The survey instrument was designed to measure responses to the following attitudinal variables: acceptance and nonacceptance of a CML program; importance to patient care, education, and research; influence on information-seeking patterns of health care professionals; ethical issues; CML extension services; and costs. Seventy-nine usable questionnaires out of a total of 120 (66%) were obtained from clinical medical personnel, and 30 usable questionnaires out of a total of 40 (75%) were obtained from medical school library directors. Survey results indicated significant differences between clinical medical personnel and library personnel regarding attitudes toward CML influence on information-seeking patterns, ethics, alternative CML services, and costs. Survey results also indicated a continuing strong support for CML programs in the medical school setting; however, differences of opinion existed toward defining the role of the CML and determining responsibility for funding.  相似文献   

Greetings from the Editor     

Linda K. Huber  Nancy J. Hoffman 《Journal of Early Childhood Teacher Education》2013,34(2):97-101

The eight early childhood educators who participated in this study were admitted into a 60-credit statewide distance-delivered Associate of Applied Science (AAS) degree program at the University of Alaska. All eight educators were women of Alaska Native ancestry who lived and worked in remote and rural Native communities. Seven of these teachers were employed by Head Start programs and one taught preschool for a rural school district. A major goal of the statewide distance-delivered AAS program is that participants will become skilled observers of children and learn to use observation to make decisions that foster developmentally appropriate and culturally responsive services. All the course work in our AAS degree program involves actively doing and using observations of children. This study is based on a principle that intrinsic changes can occur in program management, curriculum development, and teacher practice when teachers learn how to use observation of children rather than external evaluation to make decisions about their programs.  相似文献   

中德学生数学建模能力水平的比较分析——以中国上海和德国巴登符腾堡州学生为例   总被引：1，自引：0，他引：1
