The main aim of this article is to analyse the change of adult skills, as captured by cognitive skills assessed in PIAAC, across age cohorts, taking into account that the quality of schooling may change from one cohort to another. We estimate a model that relates numeracy and literacy skills to age, schooling, gender and variables related to both family background and labour market performance. The specification allows us to control for changes in the efficiency of the transformation of schooling into skills when drawing age‐skill profiles. Our results show that the effect of ageing on skills, once isolated from cohort effects related to schooling, decreases monotonically across consecutive cohorts. The change of the efficiency of the transformation of schooling into both numeracy and literacy skills shows a remarkably similar pattern. Nonetheless, this change differs substantially between education levels, with the efficiency of the transformation of schooling into skills showing a steadier profile for intermediate than for higher education. Finally, empirical evidence is provided for the decomposition of the differences in the skill levels of the older vs. the prime age generations. The results suggest that the progressive expansion of schooling across younger generations partially offsets the negative effect of the irrepressible ageing of society on skills. 相似文献

In this paper the authors present a preliminary discussion on some of the results from a survey aimed to explore, describe and explain some of the usability characteristics in digital libraries evaluation in the Mexican context. The study is framed in the evaluation of a multinational and monolingual digital library: the Miguel de Cervantes Virtual Library, from the University of Alicante in Spain. The evaluators were Mexican “expert” users (i.e. Spanish-speaking professional university librarians specialized in electronic reference services) who were asked to carry on an evaluation instrument based on usability criteria as taken from some models in developed countries. Some questions that might be answered with future research are outlined in this paper. 相似文献

The aim of this study was to investigate, for typical shoes and surfaces used in tennis, the relative role of the shoe and
surface in providing cushioning during running. Five test surfaces ranging from concrete to artificial turf were selected,
together with two shoe models. Impact absorbing ability was assessed mechanically using drop test procedures and biomechanically
using peak magnitude and rate of loading of impact force and peak in-shoe pressure data at the lateral heel. Differences in
biomechanical variables between shoe-surface combinations were identified using a two-way ANOVA (p < 0.05). Mechanical test results were found to rank the surfaces in the same order regardless of the shoe model, suggesting
that the surface is influential in providing cushioning. However, for all mechanical and biomechanical (p < 0.05) variables representing impact absorbing ability, it was found that the difference between shoes was markedly greater
than the differences between surfaces. The peak heel pressure data were found to rank the surfaces in the same order as the
mechanical tests, while impact force data were not as sensitive to the changes in surface. Correlations between mechanical
and biomechanical impact absorption highlighted the importance of testing the shoe-surface combination in mechanical tests,
rather than the surface alone. In conclusion, mechanical testing of the shoe-surface combination was found to provide a strong
predictor of the impact absorbing ability during running if pressure data were used. In addition, for typical shoe-surface
combinations in tennis, the shoe was found to have more potential than the surface to influence impact loading during running.
Finally, in-shoe pressure data were found to be more sensitive than force plate data to changes in material cushioning. 相似文献

This paper investigates the relationship between ability to detect changes in prosody and reading performance in Spanish. Participants were children aged 7–8 years. Their tasks consisted of reading words, reading non‐words, stressing non‐words and reproducing sequences of two, three or four non‐words by pressing the corresponding keys on the computer keyboard. Non‐word sequences were constructed with minimal non‐word pairs differing in a single phoneme (/kúpi/ ‐ /kúti/) or in the stress pattern (/mípa/ ‐ /mipá/). Results showed that performance on phoneme contrast sequences (e.g. /kúpi/ ‐ /kúti/) predicted word reading. In contrast, performance on stress contrast sequences (e.g. /mípa/ ‐ /mipá/) predicted non‐word reading, but only when two‐non‐word sequences were analysed. This suggests that stress sensitivity may be one of the factors related to reading fluency as most errors at reading non‐words consisted of false starts and pauses between syllables. Results also showed that stress sensitivity (scored in two non‐word sequences) predicted stress assignment, and that knowledge of stress rules predicted both word and non‐word reading. This suggests that stress sensitivity may help in learning stress rules, and that knowledge of stress rules is relevant for reading. 相似文献

Aims: The aims of this research were to determine the background, education, training experience, roles and responsibilities of practising Clinical Librarians (CL) in the UK. This paper reports the findings of a survey undertaken in 2007 at the third Clinical Librarian conference. This research builds on research undertaken by Harrison and Sargeant in 2002 and Ward in 2004, and can be considered as part of a longitudinal study of the role of the CL in the UK. Objectives: The objectives of the research were to define and gain a broad understanding of the role of the CL in the UK highlighting similarities and differences amongst the professionals and provide evidence for a baseline of skills and activities for the CL role. The type of sampling used was Judgemental. Results/analysis: Results/analysis detail the skills and activities undertaken by CLs. Searching for information for Clinicians was the activity most frequently undertaken. Developing good relationships with other healthcare professionals was considered essential. Two‐thirds of the respondents held a postgraduate library qualification. Conclusions: Crucially a new model for the UK CL role is derived drawing on the findings of this study and the existing literature. 相似文献

This study examined the effect of (a) high- and low-level questions and (b) reading the text before the questions asked on performance, delayed text recall, and deep text comprehension, as well as on specific text-inspection patterns. Participants were 37 undergraduate students who answered either high- or low-level questions using the software Read&Answer to read and answer questions on the computer screen. Additionally, half of the sample read first a text and then answered the questions (reading-first condition), whereas the other half answered the questions without having read the text in advance (no-reading-first condition). All participants had the text available to search for the answer. Results indicated that high-level questions facilitated deep comprehension but not immediate performance or delayed recall of text, independently of the reading condition, and that high- and low-level questions differentially affected text-inspection patterns. 相似文献

This paper aims to analyze gender verifications in sport from a socio-historical approach. These medical controls intended to keep men from competing in women's international competitions. Some female athletes are put through a masculinization trial, because of morphologies and performances judged as too masculine. Facing these athletes who disrupt the representation of a binary construction between the male sex and the female sex, sports institutions attempt to maintain a sexual bi-categorization. More precisely, this paper will present the ‘symbolic’ suppression of tests since 2000. Thereafter, authorities only rely on an aesthetic and visual assessment of female bodies and no longer use tests in a systematic and obligatory fashion. This reveals the moving boundary subjectively plotted between the masculine and the feminine, which become all the more blurred when the ‘race and class markers’ interfere with the ‘sex markers’. 相似文献
