Can public arts education replace arts subsidization?     

Luc Champarnaud  Victor Ginsburgh  Philippe Michel 《Journal of Cultural Economics》2008,32(2):109-126

The debate about whether the arts should be supported or not is far from new, and most governments support the arts in one way or the other. The literature considers several arguments in favor of such interventions. Public education may seem to be an action which could, in the long run, lead to possible reductions of subsidies. Surveys show that those who have been exposed to the arts when young participate more when adult. However, the “non-market” transmission from parents to children generates an external effect, which has to be taken into account to reach first-best situations. We construct an overlapping generations model in which young consumers are exposed to both public education toward the arts and to non-altruistic transmission of such a taste from their parents. We show that the first-best can be reached only if there is both public cultural education and subsidization of arts consumption. Therefore, education cannot be considered as a substitute for subsidies to arts consumption. However, as is often the case in European countries, government intervention is usually below the first-best level. Using a model calibrated on French data, we show that it is then preferable to subsidize education, while consumption, especially of the older generations, should be taxed rather than subsidized.

Hooligans,Casuals, Independents: Decivilisation or Rationalisation of the Activity?     

Dominique Bodin  Luc Robène 《国际体育史杂志》2014,31(16):2013-2033

If there is one phenomenon which highlights the lack of role distance of certain sport actors, it is obviously hooliganism. In the mid-1980s, Norbert Elias and Eric Dunning became interested in the role played by modern sports in the ‘civilising process’ and, analysing the violence of sport crowds, introduced a culturalist interpretation of the actions. They were considered to be the work of members of the ‘rough working class’, who were less advanced in the ‘civilising process’ and had still not achieved sufficient self-control. In these groups, characterised by social functioning in the form of a segmentary bond, violence was thought to be a traditional way of resolving conflicts, a significant aspect and essential part of their ethos. This is an over-determined interpretation of the violence of sports crowds which naturalises and socialises this violence. This vision poses a problem, that of the negation of any logic on the part of the actors involved. This viewpoint leads us to consider violence as a social product and a ‘practical accomplishment’, the result of the way in which supporters interpret and live in the world that surrounds them, and, as such, it is the individual and collective motives and purposes that should be investigated.  相似文献   

Prices for superstars can flatten out     

Luc Champarnaud 《Journal of Cultural Economics》2014,38(4):369-384

We reconsider Rosen’s economics of superstars model establishing, in the case of single-type consumers, a constant price-to-quality ratio. Rosen also conjectured that, in the case of multiple-type consumers, the normal course of consumer behavior forces the price-to-quality relationship to be convex and prevents it from being concave. We show that this conjecture is false and explain why there is no a priori reason to rule out concavity in the price-to-quality relationship. In this model, the market matches consumers to artists on the basis of quality: consumers of each type select only one level of quality, supplied by artists endowed with a specific level of talent. The concavity or convexity of the price-to-quality relationship is non-trivially related to the way both populations are matched. Consumers with poor knowledge have greater fixed costs above and beyond the price they have to pay on the market. They are therefore less reluctant when prices rise sharply and they specialize in levels of quality that entail a high marginal appreciation of quality: this can mean either a high or a low level of quality, depending on price curvature. With convexity, as Rosen pointed out, they turn toward superstars. Symmetrically, convexity encourages connoisseurs to turn toward low quality. But concavity too is fully possible: consumer–artist matching, for the same reasons, simply has the reverse effect. Connoisseurs go for great talents, whose price of quality flattens out. The global shape of the price-to-quality relationship (concave or convex) is determined by market clearing conditions and, more crucially, by the distribution of agents on both sides.  相似文献   

Design of a fast real-time LPV model predictive control system for semi-active suspension control of a full vehicle     

Marcelo Menezes Morato  Manh Quan Nguyen  Olivier Sename  Luc Dugard 《Journal of The Franklin Institute》2019,356(3):1196-1224

This article is concerned with the control of a Semi-Active suspension system of a 7DOF Full Vehicle model, equipped with four Electro Rheological (ER) dampers, taking into account their incipient dissipativity constraints. Herein, a real-time, fast, advanced control structure is presented within the Model Predictive Control framework for Linear Parameter Varying (LPV) systems. The control algorithm is developed to provide a suitable trade-off between comfort and handling performances of the vehicle in a very limited sampling period ($T_s=5\text{ms}$), in view of a possible realtime implementation on a real vehicle. The control structure is tested and compared to other standard fast control approaches. Full nonlinear realistic simulation results illustrate the overall good operation and behaviour of the proposed control approach.  相似文献

A System of Student Feedback: Considerations of Academic Staff Taken into Account     

Veerle Hulpiau  Evelien Masschelein  Luc Van Der Stockt  Piet Verhesschen  Kim Waeytens 《Tertiary Education and Management》2013,19(1):35-45

As a consequence of the suspension of a system of yearly evaluations of individual courses with student questionnaires, the University of Leuven organised a broad consultation of the academic community focussing on what they expect from a system based on student feedback. The study revealed that this community attaches great importance to a clear definition of the goals of student feedback, improvement and accountability, and a logical translation of these goals into a concrete approach. The study also confirmed the need of academic staff for a concrete response to the importance they give to quality improvement and enhancement besides accountability.  相似文献   

Study of Post-World War II French Aeronautical Aluminium Alloy and Coatings: Historical and Materials Science Approach

ABSTRACT

In many countries, collections of historic aircraft, conserved in Air and Space museums or local associations, reflect the importance of a national or local history. Mostly parked outdoors, aircraft suffer from significant corrosion requiring conservation operations. During renovation, metallic parts are often replaced by association members. This can lead to a major loss of information since industrial archives dealing with materials and processes do not always survive. However, if these elements can be considered, they could be a fundamental source of information on the materials originally used and of the technical history of aeronautics. This work reports a thorough study of aluminium-based alloy parts collected on a Breguet aeroplane dating from the 1950s, during its recent renovation. Thanks to an approach coupling multi-scale material characterisation and research in archives, information on the industrial knowledge is revealed. Several historic grades of aluminium-based alloys were found, namely A-U4G, A-U4G1, and A-U3G, depending on the role of the part. Similarly, different protective coatings were identified (anodic oxidation, primers, and paintings), depending on the role of the metallic part and its location in the plane. Knowledge of the materials from bulk metal to the coated surface is necessary for good conservation practices regarding aeronautical heritage artefacts. Related documents and archives also fundamentally help in understanding such complex artefacts.  相似文献   

A cultural lens on Yucatec Maya families’ COVID-19 experiences     

Lucía Alcalá  Suzanne Gaskins  Lindsey E. Richland 《Child development》2021,92(5):e851-e865

Health guidance during the COVID-19 pandemic led families around the world to spend more time isolated together, disrupting leisure activities, schooling, social interactions, and family work (UNICEF, 2021). Using the lens of Yucatec Maya families’ cultural values and practices, semi-structured interviews were conducted with 18 Yucatec Maya rural women in Mexico (M_age = 32; and for comparison, 13 middle-class European-American women (M_age = 41)), with children 6–7 years old, to analyze families’ experiences during the pandemic. Faced with the same isolation as in the United States, our exploratory analysis revealed Maya families experienced external stresses but at the same time were generally comfortable with their children's everyday activities and their social-emotional well-being, illuminating consequences of the communities’ cultural theories about development.  相似文献
