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

The school closures owing to the 2020 COVID-19 crisis resulted in a significant disruption of education provision, leading to fears of learning losses and of an increase in educational inequality. This article evaluates the effects of school closures based on standardised tests in the last year of primary school in the Dutch-speaking Flemish region of Belgium. Using a 6-year panel, we find that students of the 2020 cohort experienced significant learning losses in three out of five tested subjects, with a decrease in school averages of mathematics scores of 0.17 standard deviations and Dutch scores (reading, writing, language) of 0.19 standard deviations as compared to previous cohorts. This finding holds when accounting for school characteristics, standardised tests in Grade 4 and school fixed effects. Given the large observed effect sizes, the effect of school closures appears to be a combination of lost learning progress and learning loss. Moreover, we observe that inequality both within schools and across schools rises by 7% for mathematics and 8% for Dutch. The learning losses are correlated with observed school characteristics, as schools with a more disadvantaged student population experience larger learning losses. 相似文献

A straightforward way to prevent students from leaving education without a higher secondary diploma is increasing the compulsory education age. The idea is that, by staying longer in school, more students eventually obtain a higher secondary diploma. This paper examines the impact of a one-year increase in compulsory school-age on dropping out of secondary education by a difference-in-differences analysis. For this, we exploit a recent compulsory education policy reform in the Netherlands. After controlling for confounding factors and observable covariates, we find that the one year increase in compulsory school-age reduces dropout by 2.5 percentage points. The effect, however, is entirely situated in the group non-liable to the policy reform. We observe that native Dutch vocational students, mostly without retention in grade, but also without a higher secondary diploma at hand, more often left school in the immediate period before the policy reform. Given the economic revival at that time, this may reflect anticipation of labor market opportunities. 相似文献

Library managers are continuously urged to provide better library services at a lower cost. To cope with these cost pressures, library management needs to improve its understanding of the relevant cost drivers. Through a case study, we show how to perform time-driven activity-based costing for a library acquisition process in a Belgian university and provide evidence of the benefits of such an analysis. 相似文献

High- and low-IQ children in the first, third, and fifth grades performed two free-recall tasks: a sort-recall task with sets of categorically related pictures, and a class-recall task, with children recalling the current members of their school class. All children were deemed to be experts concerning the composition of their school class, but, unlike experts in other domains, had no special motivation associated with their expertise. Recall and clustering on both tasks were high. The high-IQ children performed better than low-IQ children only on the sort-recall task. IQ was significantly correlated with measures of performance on the sort-recall task but not on the class-recall task. The results reflect the fact that the memory benefits associated with being an expert (here, elimination of IQ effects) are related to the greater knowledge the expert possesses and not to factors of motivation. 相似文献

Estimating scale economies and the optimal size of school districts: A flexible form approach 下载免费PDF全文
下载免费PDF全文 This paper investigates estimation methods to model the relationship between school district size, costs per student and the organisation of school districts. We show that the assumptions on the functional form strongly affect the estimated scale economies and offer two possible solutions to allow for more flexibility in the estimation method. First, we introduce a model by adding higher‐degree district size polynomials, allowing for multiple optima. Second, we develop a Fourier cost function, innovative in the literature on scale economies in education. We then compare both models to classical approaches in the literature. We illustrate how a minor change in the estimation method can alter policy conclusions significantly using Flemish school district data. In doing so, we find sizeable potential cost savings from the consolidation of school districts, especially at the lower tail of the district–size distribution. The organisational transition from small to large school districts is characterised by an interval between two optima. Beyond an apparent slowdown in cost savings in medium‐sized school districts, cost savings from school district consolidation increase again, up to the optimal size of around 6,500 students. Beyond this optimum, school districts incur diseconomies of scale. The commonly used quadratic form (‘U’‐shaped cost function) overestimates scale economies, and fails to identify the interval between both optima. 相似文献

This article presents a comparative analysis of the determinants of early school leaving (ESL) at the country level. We decompose ESL rates into two components: a ‘primary’ rate reflecting unqualified school leaving from initial education, and a second component accounting for early school leavers who participate in training programmes. Both may be influenced by structural and policy determinants. We examine how the ESL rate is affected by macro-economic and social context variables such as GDP/capita, growth, poverty, and youth unemployment, as well as system characteristics of the education system (such as legal school leaving age, grade retention, early tracking, and size of vocational education) and the labour market and social protection systems (minimum wages, unemployment insurance). 相似文献

The purpose of this study was to determine the association between weightlifting performance and vertical barbell acceleration patterns. Barbell kinematic time-series data were tracked from 18 snatches from six weightlifters during a regional weightlifting competition. These data were used to calculate vertical barbell accelerations. Time-series data were normalised to 100% of lift phase, defined as the time interval between barbell lift-off and maximum height of the barbell during each snatch lift. The time-series data were then entered into a pattern recognition algorithm that extracted principal patterns and calculated principal pattern scores. Body mass-normalised lift weight, which was used to quantify weightlifting performance, was significantly correlated (r = 0.673; P = 0.033) with a pattern that captured a difference in peak vertical barbell acceleration between the transition and the second pull phase. This correlation indicated that barbell acceleration profiles of higher weight snatch lifts were characterised by smaller decreases in acceleration during the second knee bend and smaller peak acceleration during the second pull phase. Weightlifting coaches and sports scientist should monitor and track vertical acceleration of the barbell, with focus on acceleration profiles that limit (1) deceleration during the transition phase between the first and second pull and (2) peak acceleration during the second pull phase of the snatch. 相似文献

The present experiment contrasted the recall of gifted and nongifted middle-school children for sets of categorically related items. Subjects were given a single free-recall trial on each of two lists consisting of category-typical and category-atypical words. The typicality of the items for one list was based on each subject's unique typicality ratings, whereas the typicality of the items in the second list was based on adult norms. A preliminary category-rating task indicated that gifted students were somewhat more similar to adults in their ratings of category typicality than nongifted children. Recall was comparable between the gifted and nongifted subjects for typical items, but greater for the gifted subjects for atypical items. The latency between the recall of unrelated words was faster for the gifted than the nongifted children. Subjects were classified as strategic or nonstrategic on the basis of clustering and interitem latencies. Gifted subjects were less apt to be classified as strategic than nongifted subjects on the typical items of the self-generated list; there were no differences in the classification between the gifted and nongifted children for all other contrasts. These results were interpreted as indicating that the cognitive advantage of gifted relative to nongifted children is more apt to be in terms of nonstrategic rather than strategic functioning. 相似文献
