This paper analyses how the interaction between social institutions on the one hand and actors’ strategies and interests on the other hand is shaping European integration in research policy. We specifically focus on the implications of the existence of different conceptions of European integration (logics) on the emerging landscape of research funding programs jointly managed by the European Union (EU) and National States (joint programs). Our results display the central role of the introduction of a logic of coordination by the EU; it created a breeding ground for a new generation of programs and, at the same time, allowed to make the integration model more flexible and acceptable to National States (as funding became only virtually integrated). Most newly created programs were characterized by largely symbolic commitments and very small budgets, while stronger commitments had to be constructed through successive steps of integration. This process was highly selective and dependent on the presence of strong interests from the research community; additional funding from the EU was critical to ensure stability of national commitments. Further, National States by large delegated to independent funding agencies the management of national participations: delegation allowed to achieve greater homogeneity among national participants, but also to decouple decisions to participate (driven by compliance to institutional pressures) from the level of resources to be committed (driven by national interests). While in the year 2000, the European Research Area (ERA) strategy of coordinating national research policies was largely an empty concept, our case study shows how in the following decade, it was filled in with specific experiences and practices, led to the redefinition of actors’ understanding of European integration and roles in European research policies and, ultimately, to the emergence of original models of integration.  相似文献

Humanoid robots have shown to provide interesting perspectives for autistic children. Yet, few studies have looked at educators' point of view on the use of such robots in educational settings. This paper presents a case study of the use of a humanoid robot, NAO, in a French preschool class dedicated to autistic children. Our work focuses on the perspectives of the adults working with these children. We interviewed the professional staff about changes in their teaching due to the presence of the robot, about the effects on the pupils' behaviour, and about the collaboration between the special needs teacher, the special needs support worker and the operational specialist from the digital education department of the district academic head office. Four themes were identified: joint reflection and collaboration when working with NAO, working with NAO, impact of NAO on pupils, impact of NAO on adults. The professionals underscored the necessity of adopting certain attitudes, in particular, the most neutral facial expression possible, so as not to disturb the children's learning process. They were under the impression that the robot had a beneficial effect on the pupils in terms of learning and social skills, and that it facilitated collaboration among them.  相似文献

In their paper on price comovements of paintings, Ginsburgh and Jeanfils show that in three important markets (London, Paris and New York), prices of well-known and lesser known painters 'move together' (are cointegrated). They conclude that therefore, an investor may be indifferent between the two groups of painters. We show that this is not the case, since well-known painters are less risky, and that though returns may be comparable, the share of well-known painters in a portfolio of paintings might be as high as 90%. We also construct long-run and short-run portfolios and show that these may be very different. These short-term portfolios give interesting insights which help in characterizing each of the three markets.  相似文献

In achievement contexts such as sport, achievement goal theory assumes that an individual's major concern is to demonstrate competence. However, competence may be expressed in two ways: as task and ego involvement (Nicholls, 1989). Seventy-eight boys (M age = 13.6 years) performed five climbing courses, and the influence of achievement goals, perceived ability, and task difficulty on effort and performance was studied. According to the achievement goal theory: (a) task-involved boys exerted more effort and performed better than ego-involved boys; and (b) exerted effort was determined by an interaction of one's achievement goal, perceived ability (PA), and task difficulty. Ego-high PA boys and task-low PA boys exerted the most effort on the moderate course; ego-low PA boys exerted least effort on the moderate and very difficult courses. Finally, task-high PA boys exerted more effort on the most difficult courses. The motivational processes underlying these findings are discussed.  相似文献

For more than three centuries broadsheets were an important means of quickly disseminating and commenting on the news of the day. They depicted a wide range of events of historical significance, including some of the more striking celestial phenomena such as the appearance of comets. Those that survive often do no more than repeat knowledge that can readily be gained from conventional sources but some have proved of direct value in making astronomical computations and deductions.  相似文献

This within‐subjects experimental study investigated the influence of the arts on cortisol for economically disadvantaged children. Participants were 310 children, ages 3–5 years, who attended a Head Start preschool and were randomly assigned to participate in different schedules of arts and homeroom classes on different days of the week. Cortisol was sampled at morning baseline and after arts and homeroom classes on two different days at start, middle, and end of the year. For music, dance, and visual arts, grouped and separately, results of piecewise hierarchical linear modeling with time‐varying predictors suggested cortisol was lower after an arts versus homeroom class at middle and end of the year but not start of the year. Implications concern the impact of arts on cortisol for children facing poverty risks.  相似文献
