The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation. 相似文献

All countries and particularly the less developed face serious difficulties in the financing of higher education. This has also been true of Colombia, where private higher education has grown more rapidly than the official sector to the point of accounting for 60% of total enrollment due to the State's inability to increase the number of its institutions and to provide them with growing budgets.Given the greater efficiency in expenditure demonstrated by private institutions, a comparison is made of their income and expenditure structure with that of public institutions and differences are established in order to define those areas in which greater internal efficiency can be achieved.In spite of the total cost of higher education in Colombia it is relatively low due to the prevalence of low salaries and lack of equipment or sophisticated facilities and due also to the fact that research is still in an incipient stage.Faced with problems of fairness toward lower income families that must pay more than they can afford, or on the other hand, those who could pay more but are receiving free state education, a state subsidy is proposed to carry out a direct transfer to the student, while all state universities would charge tuition that would cover the cost of instruction. This subsidy should be channelled through ICETEX, a pioneer institution in the world in the field of student financing through credit. Several sources of student financing are examined that reflect a more realistic way of responsibly subsidizing study. 相似文献

Despite the growing body of research on work engagement, little is known about what drives work engagement among different age cohorts. This study aims to investigate whether engagement varies across age cohorts and examine the job resources that foster teacher engagement. A questionnaire was distributed to 537 teachers who were employed in elementary, lower and upper secondary school. Findings show that work engagement did indeed vary across the diverse age group and is influenced by different resources. In line with previous studies, data revealed that the engagement of younger teachers is driven by the opportunity for development and interaction with colleagues, while older employees appreciate the opportunity to see their competencies acknowledged. What is most noteworthy is the opportunity to design practices and to provide every age group with the appropriate set of motivators. 相似文献

Multimedia computer programmes have been found to facilitate learning in children with Autistic Spectrum Disorders (ASD). However, the effectiveness of these resources is limited due to poor design or a lack of consideration of the ASD cognitive profile, particularly at the lower functioning end of the spectrum. This article attempts to tackle the problem of the lack of design guidelines, with the aim of facilitating the development of effective educational programmes for children with severe ASD. The case study reported here evaluated two literacy educational computer programmes, by observing five low-functioning children with ASD, compared to five neurotypical children (control cases). The two types of reading-support software contrasted in the study presented different characteristics. The children’s data analysed here concern observations of child–software interactive sessions based on video recordings and coded for attention deployment to each programme, including motivation and engagement indicators. 相似文献

Academic self-concept and academic interest are crucial concepts for understanding students’ academic achievement. Yet, few
questionnaires currently exist that have been used and validated in more than one country. This study aimed at assessing these
concepts using an academic self-concept questionnaire (Marsh, 1990) and an academic interest questionnaire (Corbière & Mbekou,
1997) with French and Italian student samples. Confirmatory Factor Analyses enabled us to assess the structure of the two
questionnaires with regard to two academic subjects — Math and First Language (French or Italian) — and to determine the theoretical
directions between the concepts. Results from Confirmatory Factor Analyses of both French and Italian samples supported a
theoretical model in which academic self-concept and academic interest were intercorrelated, yet maintaining their unique
characteristics. On the other hand, results from Multi-Sample Confirmatory Factor Analyses (French and Italian samples) endorsed
a correlational model between the two concepts. Finally, the results indicated a significant and positive correlation between
academic self-concept, academic interest, and academic achievement in both academic subjects. 相似文献

Knee injuries such as anterior cruciate ligament lesions and patellar tendonitis are very frequent in volleyball, and are often attributed to micro traumas that occur during the landing phase of airborne actions. The aim of the present study was to compare different jumping activities during official men's and women's volleyball games. Twelve top-level matches from the Italian men's and women's professional leagues were analysed. The jumps performed during the games were classified according to the landing technique used by the player (left or right foot or both feet together), court position, and ball trajectory. Chi-square analyses were performed to detect differences in landing techniques between the sexes, court positions, and trajectories when serving, attacking, blocking, and setting. Significant differences (P?0.05) were found between the sexes for block, set, and spike but not for the jump serve. The frequency of landings on one foot was related to court position and the trajectory of the sets: when spiking faster sets, the players were more likely to use a one-footed landing. The present results should help coaches and physiotherapists to devise appropriate training and prevention programmes, and reveal the need for further detailed biomechanical investigations of the relationships between landings and knee injuries. 相似文献

Abstract The aim of this study was to examine the effects of exercise type, field dimensions, and coach encouragement on the intensity and reproducibility of small-sided games. Data were collected on 20 amateur soccer players (body mass 73.1 ± 8.6 kg, stature 1.79 ± 0.05 m, age 24.5 ± 4.1 years, [Vdot]O2max 56.3 ± 4.8 ml · kg?1 · min?1). Aerobic interval training was performed during three-, four-, five- and six-a-side games on three differently sized pitches, with and without coach encouragement. Heart rate, rating of perceived exertion (RPE) on the CR10-scale, and blood lactate concentration were measured. Main effects were found for exercise type, field dimensions, and coach encouragement (P < 0.05), but there were no interactions between any of the variables (P > 0.15). During a six-a-side game on a small pitch without coach encouragement, exercise intensity was 84 ± 5% of maximal heart rate, blood lactate concentration was 3.4 ± 1.0 mmol · l?1, and the RPE was 4.8. During a three-a-side game on a larger pitch with coach encouragement, exercise intensity was 91 ± 2% of maximal heart rate, blood lactate concentration was 6.5 ± 1.5 mmol · l?1, and the RPE was 7.2. Typical error expressed as a coefficient of variation ranged from 2.0 to 5.4% for percent maximal heart rate, from 10.4 to 43.7% for blood lactate concentration, and from 5.5 to 31.9% for RPE. The results demonstrate that exercise intensity during small-sided soccer games can be manipulated by varying the exercise type, the field dimensions, and whether there is any coach encouragement. By using different combinations of these factors, coaches can modulate exercise intensity within the high-intensity zone and control the aerobic training stimulus. 相似文献

The authors explored whether manipulating feedback influenced cognition, motivation, and achievement in an undergraduate chemistry course. They measured students’ (N = 250) achievement goals, test anxiety, self-efficacy, and metacognitive strategy use at the beginning and end of the semester. After completing the first set of questionnaires, students were randomly assigned to 1 of 4 conditions: (a) control, (b) mastery feedback, (c) performance-approach feedback, and (d) combined mastery/performance-approach feedback. In each condition, students received a raw performance score for each weekly quiz they completed online and, for the treatment conditions, additional feedback reflective of that specific feedback condition. Results provide evidence for the multiple goals perspective (specialized pattern) wherein performance-oriented feedback was beneficial for some outcomes, whereas mastery feedback was beneficial for other outcomes. 相似文献

Auditory Context and Memory Retrieval in Young Infants 总被引:1,自引:0,他引:1

Three-month-old infants were trained to move an overhead crib mobile while 1 of 2 musical selections was played. Retention was assessed 1 or 7 days later in the presence of either the same music or a different musical selection. in Experiment 1, the musical selections were very different (classical versus jazz); in Experiment 2, they were much more similar (two classical pieces). Infants in both experiments displayed 1 day retention regardless of wich music was played during the retention test. At 7 days, retention was seen only when the music played during the retention test matched the training music. These data are consistent with similar findings showing that 3-month-old infants'memory is disrupted at long retention intervals when the context present during retention testing does not match the learning context. As the infant's memory wanes, context appears to function as a necessary cue for the retrieval of acquired expectancies. 相似文献
