Academic Self-Efficacy Beliefs and Quality of Experience in Learning   总被引:1,自引:0,他引:1  
This study investigated learning activities and associated quality of experience of students with different levels of perceived academic self-efficacy. Two groups were formed out of 130 Italian adolescents (age 15–19), one with high and one with low academic self-efficacy beliefs (31 and 32 participants, respectively). Students provided valuation of academic pursuits and aspirations, and were monitored for one week with experience sampling method (ESM). Attention was paid to the association of learning activities with optimal experience, characterized by high perceived environmental challenges matched by high personal skills, involvement, concentration and intrinsic reward. High self-efficacy students reported higher academic aspirations and pursuits than low self-efficacy students. They also spent more time in homework, and primarily associated learning activities with optimal experience. Results have educational implications in fostering motivation and enjoyment in learning. They also provide empirical support for the combination of self-efficacy beliefs and quality of experience in motivational research.

There is increasing interest in the issue of informal payments for health care in low- and middle-income countries. Emerging evidence suggests that the phenomenon is both diverse, including many variants from cash payments to in-kind contributions and from gift giving to informal charging, and widespread, reported from countries in at least three continents. However, cross-national research is hampered by the lack of consensus among researchers on the definition of informal payments, and the definitions that have been proposed are unable to incorporate all forms of the phenomenon that have been described so far. This article aims to overcome this limitation by proposing a new definition based on the concept of entitlement for services. First, the various forms of informal payment observed in practice are reviewed briefly. Then, some of the proposed definitions are discussed, pointing out that none of the distinctive characteristics implied by these definitions, including illegality, informality, and corruption, is adequate to capture all varieties of the phenomenon. Next, an alternative definition is formulated, which identifies the distinctive feature common to all forms of informal payments as something that is contributed in addition to the terms of entitlement. Then, the boundaries implied by this definition are explored and, finally, the implications for research and policy making are discussed with reference to the lessons developed countries can learn from the experiences of transitional countries.  相似文献

We describe the investigation of the 1999 collapse of an apartment building in Foggia, Italy. Sixty-one victims were recovered in the rubble of the building, and five people were unaccounted for. All the bodies were well preserved except for two who had been burned. The majority of the victims were identified visually or by comparing body features, clothing, or personal effects with information collected from relatives or friends. Positive identifications of the two victims who were burned were obtained by dental comparison and DNA analysis. Approximately half of the victims (51.6%) sustained fatal injuires, while the remainder died from asphyxia. The injuries were characterized using the Abbreviated Injury Scale (AIS) and the New Injury Severity Score (NISS) systems. Injury severity associated with the location of victims inside the apartment may provide useful information for those involved in building design and/or search and rescue operations. Engineers determined that the collapse was the result of the use of inappropriate foundation material.  相似文献

In this paper we use a simple climate model for endogenous environmental technical change in order to analyse the effects on equity and efficiency of placing different degrees of restrictions on trade in the market of pollution permits. The model is obtained by incorporating in Nordhaus and Yang (1996)'s RICE model a notion of induced technical change close to the one proposed in Goulder and Mathai (2000). With the help of such a model, we assess the pros and cons of introducing ceilings on emission trading. In particular, we analyse both the cost effectiveness and the distributional effects of placing restrictions of trading emissions. The analysis takes into account the role of environmental technical change that could be enhanced by emission trade limitations. However, this effect is shown to be offset by the increased abatement cost induced by the larger than optimal adoption of domestic policy measures when ceilings are made binding. Hence, our analysis provides little support for quantitative restrictions of emission trading, even when these restrictions actually have a positive impact of technical change. Even in terms of equity, ceilings find no justification within our theoretical and modelling framework. Indeed, we find that flexibility mechanisms in the presence of endogenous technical change increase equity and that the highest equity levels are achieved without ceilings, both in the short and in the long run.  相似文献

The authors describe a particular form of football hooliganism, namely the behaviour displayed by particular groups of young fans - in Italy the so-called ultras - consisting of acts of vandalism and systematic aggression to the detriment of similar opposing groups both within and, above all, outside the stadiums. The development over the last decade is outlined and the authors try to explain the current situation and the most recent changes. They show that, in spite of the diminishing number of incidents in the last years, this violence is changing appearance: on the one hand, it turns against the police; on the other hand it declines into pure vandalism and juvenile deviance. An important moment was the crisis caused by the death of an ultras in 1995, which marked a turning point between the 'old way' of the ultras and the new developments. A brief comparison is made with the English situation, both on the appearance of hooliganism as well as on the preventive policies, the police and the legislation on acts of hooliganism and sports violence.Italian Association of Sport for All  相似文献

Although populism and technocracy increasingly appear as the two organising poles of politics in contemporary Western democracies, the exact nature of their relationship has not been the focus of systematic attention. This article argues that whilst these two terms – and the political realities they refer to – are usually assumed to be irreducibly opposed to one another, there is also an important element of complementarity between them. This complementarity consists in the fact that both populism and technocracy are predicated upon an implicit critique of a specific political form, referred to in this article as ‘party democracy’. This is defined as a political regime based on two key features: the mediation of political conflicts through the institution of political parties and a procedural conception of political legitimacy according to which political outcomes are legitimate to the extent that they are the product of a set of democratic procedures revolving around the principles of parliamentary deliberation and electoral competition. This argument is made through a close analysis of works by Ernesto Laclau and Pierre Rosanvallon, chosen as exemplary manifestations of the contemporary cases for populism and technocracy, respectively.  相似文献

Already introduced to the academic and political debate some years ago, the concept of “security governance” still needs to be clarified. In particular, four main shortcomings need to be overcome to make the concept more useful for an assessment of current security dynamics: in the first place, attention has been devoted more to “governance” than to “security”, while failing to consider the role of the understandings and perceptions of the actors involved in the governance system. Second, the literature on the actors (governmental or not) involved is still fragmented. Third, the literature on security governance has too often been detached from reflections on regionalism, while it would be useful to further explore the relationship between cognitive definitions of regional and security dynamics. Fourth, the literature has predominantly focused on Europe and the transatlantic area, overlooking processes of “region-building” in security terms in other “unexpected” geographical spaces. After proposing avenues to overcome the current gaps in the literature, the Southern Caucasus is chosen as a case study to show the different instances of security governance emerging, thanks to definitions of the region in security terms that have involved regional and external actors, of a state and non-state nature.  相似文献
