The knowledge production provided by universities is essential to sustaining a country’s long-term economic growth and international competitiveness. Many nations are thus driving to create sustainable and effective funding environments. The evaluation of university knowledge, productivity and research quality becomes critical, with ever increasing share of public funding allocated on the basis of research assessment exercises. Nevertheless, the existing methods to assess the universities’ knowledge production are often affected by limits and biases, extensively discussed in the scientific literature.In this paper we study how to reduce the effect of size-related bias due to university size on the indicators of knowledge performance used in evaluation exercises. We propose an innovative utilization of the scale-free property of the power laws as a scaling relationship, to normalize research productivity indicators, and provide results independent by the university size. Our method has evident policy implications and gives a contribution for the future design of assessment exercises.We apply our findings in a recent Italian research assessment exercise. 相似文献

According to dual-route models of reading,consistency effects in pseudoword reading areevidence for the activation of lexicalinformation. We investigated whether thislexical interference has a semantic or anon-semantic origin. In Experiment 1,participants named aloud a set of words andpseudowords. The consistency effect in readingpseudowords co-occurred with associativepriming effects in reading words but not withsemantic priming effects. In Experiment 2, onlywords were presented. Comparable effects ofboth associative priming and semantic primingin naming words were found. This patternprovides evidence for the existence of alexical non-semantic pathway in reading aloud.It also shows that this pathway is sensitive toassociative relations among words. Finally, itcalls into question the likelihood of afeedback mechanism from the semantic system tothe orthographic input lexicon. 相似文献

AbstractEffects of reward pedagogy (competitive, cooperative, individualistic, cooperative-competitive, and cooperative-individualistic) on spelling scores and prosocial behavior in Singapore students were examined alongside its interplay with ability level. A total of 1005 Primary 3 and 4 students were randomly assigned to one of the five reward pedagogies, with students rewarded based on their spelling scores. An ABABA design (A?=?implementation; B?=?withdrawal) was used for each reward pedagogy. Results revealed an interaction between reward pedagogy and ability level on both spelling scores and prosocial behavior, such that different pedagogies were more effective for different ability levels. One promising way forward, however, draws from the finding that cooperative-competitive reward pedagogy was effective for both outcomes across all ability groups. 相似文献

The aim of this study is that of reaching a better comprehension of the topic of children’s rights within educational relationships. In a first stage, we analysed the representational field of children’s rights produced through free associations by the two partners who are in conflict in everyday life, namely adults (n=267) and adolescents (n=143). In a second stage, we chose a sample of 690 adult subjects that were all parents, half of whom were also teachers; through a structured questionnaire we investigated the role of several aspects (responsibility, respect, values, conditions influencing children’s growth and sense of justice) in the organisation of social representations of children’s rights. The results outlined different contrasts in the organisation of the representational scenario. The first opposes adults and adolescents, in the sense that adults emphasise their duties of offering protection and care, while the youngsters describe rights in terms of autonomous field of experience. Within the group of adults, several differences emerged between teachers and parents: the first seem more doubtful about the positive outcomes of personal involvement, while parents are moved by a general feeling of optimism, anchored in the faith in the family’s strength and integrity. 相似文献

A sample of 364 mothers were interviewed with a questionnaire investigating 4 topics: developmental conceptions, socialization rules, parental social roles and sexual stereotypes. A subsample of 107 of the same mothers was then submitted to an attitude scale testing the importance they attributed to 19 traits of children's behaviour and the influence they perceived as having on the development of the same traits. The results give evidence of a social representation shared by our sample; this representation refers to a traditional way of rearing children and to a traditional division of parental social roles. The mothers' working positions and levels of instructions are found to discriminate as to their agreement on such a view. Analyses on the degree of importance and of perceived influence on the behavioural traits confirm the same results, but they also define a new emerging image of the child, which stresses different values from the traditional ones. 相似文献

The purpose of this study was to investigate the changes in selected biomechanical variables in 80-m maximal sprint runs while imposing changes in step frequency (SF) and to investigate if these adaptations differ based on gender and training level. A total of 40 athletes (10 elite men and 10 women, 10 intermediate men and 10 women) participated in this study; they were requested to perform 5 trials at maximal running speed (RS): at the self-selected frequency (SFs) and at SF ±15% and ±30%SFs. Contact time (CT) and flight time (FT) as well as step length (SL) decreased with increasing SF, while kvert increased with it. At SFs, kleg was the lowest (a 20% decrease at ±30%SFs), while RS was the largest (a 12% decrease at ±30%SFs). Only small changes (1.5%) in maximal vertical force (Fmax) were observed as a function of SF, but maximum leg spring compression (ΔL) was largest at SFs and decreased by about 25% at ±30%SFs. Significant differences in Fmax, Δy, kleg and kvert were observed as a function of skill and gender (P < 0.001). Our results indicate that RS is optimised at SFs and that, while kvert follows the changes in SF, kleg is lowest at SFs. 相似文献

The impact of lighting, heating and people in re-using historical buildings are discussed for the case study concerning the ceremony room (i.e. the Giant Hall) of a mediaeval palace in Padova. The Hall has substantially four major problems for conservation: (i) the impact of heating, lighting and people when the room is used; (ii) many cracks on the oak panels of the coffered ceiling; (iii) the soiling by dust and soot particles deposited on the frescoes; (iv) the stained glass windows. A microclimate study was performed to know the impact of the environmental variables, and the use of the room, on the artworks preserved inside. The study has proved the impact of the lamps (both incandescence and compact fluorescent lamps) on the ceiling, the penetration of external air in the room, the heat and the moisture released by people, the impact of sunshine through windows and the scatter diagram of the daily cycles in temperature (T) and relative humidity (RH). During winter concerts, the strips of lead which are wrapped round the edge of the cut glass pieces in stained glass windows easily drop below the dew point and form condensation, starting corrosion. A discussion concerns the allowed variability, which should not exceed risk thresholds. A safe interval can be established within the area determined by the most frequent T and RH natural cycles. In fact, both of the cycles were compatible with the artefacts, or the artefacts were already damaged to allow the exceeding dimensional changes. Attention should be paid in the variability external to this area, especially approaching or exceeding a limit equal to twice the mode of the natural variability. 相似文献

Understanding what factors foster young people's aspirations to work as teachers is critical for designing effective recruitment policies, and for ensuring that enough youngsters enter the teaching profession. We examine what factors explain between-country differences in the percentage of 15-year-old students who expect to work as teachers as adults. We focus on two factors: (1) the salaries teachers can expect to earn compared to professionals in science, technology, engineering and mathematics (STEM); and (2) the skill levels teachers have compared to STEM professionals. Relative salaries indicate if (and to what extent) the financial returns associated with teaching careers are higher or lower than professional STEM careers dominated by men. Relative skills highlight the investment in human capital that teachers are expected to make to be able to enter the profession, as well as the social and cultural status that is associated with teaching. We used data from 29 countries that participated in the Programme for International Student Assessment and the Programme for International Assessment of Adult Competencies. In countries where teacher salaries and numeracy skills were high compared to those commanded by STEM professionals, gender gaps in teaching career expectations were smaller. High-ability students in science and mathematics were more likely to expect to work as teachers in countries where teachers have comparatively higher numeracy skills. Our findings show that when teacher salaries are competitive in relationship to the salaries of STEM professionals, more students overall expect to work as teachers. However, whilst low- and middle-performing students in science and mathematics were attracted by economic incentives, high-performing students in science and mathematics were not. 相似文献
