The number of students entering higher education started to increase significantly in the mid-1960s. This sharp growth has gone together with diversification in the social background of those attending, creation of new tracks (mainly in technology) and, more recently, a number of pedagogical innovations. Consequently, higher education students in the 1990s have little in common with those described by Pierre Bourdieu and Jean-Claude Passeron in Les héritiers, published in 1964: they are not just young bourgeois whose university career confirms ex-post the social position of his or her family. The relative democratization of access to higher education has allowed young people from other social classes to continue their studies after the baccalauréat. However, this democratization has also created new problems for higher education institutions. They must make financial, organizational and pedagogical adaptation to mass schooling. Higher education students also confront new problems in adapting to such demands of university work as autonomy and initiative. Students' living conditions have also changed: while remaining economically dependent on their parents, they enjoy, especially in the provinces, considerable freedom in the running of their personal lives.  相似文献

Who are the NEET? How much do we know about this? What do institutions and the media know about them? How different definitions could get to shared policies? This paper tries to provide an initial overview of the situation regarding the NEET, through an analysis of the emerging international literature on the subject. Different definitions across nations are analyzed in order to reflect on the cultural differences and economics-work policies, in order to then analyze more in deep the Italian situation. In Italy, the phenomenon is still little known in society and, often, not recognized by the acronym NEET, with the many variables that define it, despite statistics showing a rise in numbers (26 % of the total population for the age group considered).  相似文献

Education for sustainable development (ESD) and higher education for sustainable development (HESD) are complex, multidisciplinary fields of enquiry, drawing on concepts and terms from different disciplines and languages. Although the fields are advancing in their acceptability within educational systems worldwide, they are currently struggling to achieve sought-after graduate and societal outcomes such as environmentally-responsible or sustainability-focussed-citizenship. The research described in this article explores the possibility that miscommunication or misunderstanding of basic concepts within these fields is contributing to slow progress towards their objectives. We used a philosophical hermeneutic analysis to explore how the terms ‘competence’ and ‘capability’ are used within selected ESD/HESD papers. We identify substantial internal contradictions and inconsistencies with respect to differences between learners’ abilities and their willingness to perform these abilities, and to the educational context in which these outcomes are sought. We emphasise the importance of linking educational objectives with pedagogical approaches to teaching and assessment.  相似文献

This paper analyzes the link between cultivation of taste and tourist satisfaction during vacations. A simple model shows that, when cultural capital accumulation matters, customers are ready to sacrifice some of their current utility in order to get higher returns in future, and therefore, the relation between satisfaction and the demand for cultural goods may be convex. On the contrary, when cultivation of taste comes from learning by consuming behavior, the relation is concave. An analysis based on 1,749 interviews in Aosta Valley in Summer 2008 provides some evidence in favor of the cultural capital accumulation hypothesis.  相似文献

This study contributes to the recent empirical literature on the innovation-firm performance relationship by investigating the effect of product introduction on firm growth in a sample of Italian firms from 2000 to 2006. We adopted a novel approach that exploits the interpretative content of the tenure of the last product introduced (i.e., the number of years since its first introduction) as an additional variable into the explanatory scheme of firm sales growth rate. This variable aims to capture peculiar characteristics of new goods, such as their novelty and complexity. The estimated results confirmed the relevance of this model specification and helps in understanding the reason why previous studies have failed to find a statistically robust relationship between product innovation and growth. Moreover, we found the following: first, the release of a new product enhances growth opportunity among multiproduct firms; second, product development promotes the growth of firms belonging to sectors with stronger commitment to research and development; and third, new product development enhances firm growth substantially in those sectors that absorb externally originated patents.  相似文献

Two different analytical approaches have been taken into account to investigate the role of Si-rich phases in enhance hydraulic reactions of bedding mortar mixtures from San Lorenzo Church in Milan (Northern Italy) and from the Medicean Aqueduct in Pisa (Central Italy). In the first case, mortars show clear hydraulic type reactions in the form of coronal layers between the reacting additive and the binder mass. In the second one, the hydraulic reactions do not develop visible mineral phases and processes have been inferred from chemical, mineralogical analyses and mass balance calculation. The microstructural studies not always are sufficient to understand the complex dynamics of reaction attained during pre-industrial manufacturing processing of mortars and related binders. In fact, if the reacting raw materials are fine-grained and/or have remarkable chemical reactivity, no relicts are preserved by mortar microtextures.  相似文献

This study performed an analysis of the push-off forces of elite-short-track speed skaters using a new designed instrumented short-track speed skate with the aim to improve short-track skating performance. Four different skating strokes were distinguished for short-track speed skaters at speed. The strokes differed in stroke time, force level in both normal and lateral directions, and the centre of pressure (COP) on the blade. Within the homogeneous group of male elite speed skaters (N = 6), diversity of execution of the force patterns in the four phases of skating was evident, while skating at the same velocities. The male participants (N = 6) with a better personal record (PR) kept the COP more to the rear of their blades while hanging into the curve (r = 0.82, p < 0.05), leaving the curve (r = 0.86, p < 0.05), and entering the straight (r = 0.76, p < 0.10). Furthermore, the male skaters with a better PR showed a trend of a lower lateral peak force while entering the curve (r = 0.74, p < 0.10). Females showed a trend towards applying higher body weight normalised lateral forces than the males, while skating at imposed lower velocities.  相似文献

Twelve endurance athletes and six power athletes performed fatiguing isokinetic knee flexions/extensions. Isokinetic torque was recorded during the exercise. Isometric torque, cortisol and lactate responses, electromyographic (EMG) mean power frequency, average rectified value, and conduction velocity were analysed before and after the isokinetic exercise to determine correlations between electrophysiological variables and mechanical performances and/or blood concentrations of biomarkers in the two groups of athletes. The EMG variables were estimated from signals recorded from the vastus lateralis in both voluntary and electrically elicited isometric contractions. Power athletes recorded higher values than endurance athletes for the following variables: pre-exercise isometric maximal voluntary contraction (MVC), isokinetic MVC, rate of mechanical fatigue during isokinetic contractions, pre - post exercise variations and recovery times of conduction velocity and mean power frequency, and lactate concentrations. Moreover, conduction velocity overshooting was observed in endurance athletes during the recovery phase after exercise. The correlation analyses showed that the higher the rate of mechanical fatigue, the higher the lactate production and the reduction in conduction velocity due to the exercise.  相似文献

This study is focused on the evaluation by μRaman mapping of the penetration depth achieved by ammonium oxalate treatment in different plaster specimens, a hot issue in the conservation field. The role of the carbonatic aggregate particles and the influence of the different variables of the treatment on the penetration depth and on the distribution of the newly-formed phase (whewellite) have been ascertained. Based on the results of μRaman mapping, analyses with Field Emission Scanning Electron Microscopy have been carried out in order to observe the whewellite crystals and the carbonatic aggregate particles involved in the reaction with ammonium oxalate.  相似文献

This study is aimed at an assessment of the properties of two polymeric products applied to Norway spruce (Picea abies) and White poplar (Populus alba) wood species. It contributes to ongoing research experiments on the consolidating properties of two synthetic resins and their potential synergic action on wood, resulting from their different interaction with the substrate: Paraloid B72 and Regalrez 1126. Experiments were carried out on a series of samples of the two wood varieties. The consolidants were applied alone and one after the other, with one coat of Regalrez and then one of Paraloid. Porosity and variations in pore size distribution were ascertained by mercury intrusion porosimetry (MIP). Colorimetric and IR spectroscopic measurements were also taken before and after aging by solar radiation and freeze/thaw cycles, to verify the possible slowing of photodegradation of the treated wood and the consolidating resistance. Results confirm that both products penetrate the wood with a different behaviour. After double treatment with Regalrez + Paraloid, a significant advantage was observed in terms of mechanical resistance and pore size distribution, although no advantages as regards resistance to photo-oxidizing processes or colour changes were observed.  相似文献
