Training professionals for the new 21st century requires universities to make major changes in their conception of teaching, which, through the active, committed participation of teachers and students, will lead to the building and developing of the competencies needed by students for them to perform efficiently, ethically and with social commitment in their future jobs. The participation of teachers and students and their commitment to quality in the teacher training process are essential elements in the search for alternative ways to enhance university teaching. This article discusses the teacher training experiences had by the author in the ICE of Madrid Polytechnic University with the inclusion of data from a study undertaken on the Environmental Sciences course of this university where teachers, students and postgraduates’ perception of the quality of their vocational training at university is an important starting point for the design of strategies aimed at enhancing the quality of teaching.  相似文献

The concept of Orientalism has served to define post-colonial thinking, reflecting the West's interpretation of non-Western individuals and cultures. In this binary set, the West/us is approached as representing the standard, while the East/them represents that which is outside the norm. For the last few decades, Orientalism has continued to influence discussions in tourism studies; nevertheless, there is a dearth of empirical studies examining how the discourse lives out in daily tourism practices. Therefore, employing quantitative research methods, this study explores what Orientalism means to contemporary Americans and how it affects their attitudes toward Asian destinations. The result indicates that the imaginary construct of the East has reflected three different dimensions, namely contempt, curiosity, and fear, through which the Western world has traditionally framed the non-Western world; however, Americans generally believe that contemporary Asia cannot be adequately explained in these traditional and fixed ways. This study suggests that two terms, Asia and the East, connote very different meanings in contemporary American society, revealing how the traditional discourse of Orientalism is transformed and reinterpreted, although not totally changed, within the changing nature of the contemporary global environment.  相似文献

This paper reviews the theoretical literature on bank capital regulation and analyzes some of the approaches to redesigning the 1988 Basel Accord on capital standards. The paper starts with a review of the literature on the design of the financial system and the existence of banks. It proceeds with a presentation of the market failures that justify banking regulation and an analysis of the mechanisms that have been suggested to deal with these failures. The paper then reviews the theoretical literature on bank capital regulation. This is followed by a brief history of capital regulation since the 1988 Basel Capital Accord and a presentation of both the alternative approaches that have been put forward on setting capital standards and the Basel Committee's proposal for a new capital adequacy framework.  相似文献

This paper shows the simultaneous optimally of debt and equity contracts in a principal-agent model. The agent (an entrepreneur) has an investment project but does not have the necessary funds to finance it. There is moral hazard in the model, generated by the dependence of the project's expected return on the (unobservable) agent's effort. Key to the optimality of these financial instruments is the nonassignable rent produced by the project and captured by the entrepreneur when the investment is successful.  相似文献

Abstract:

This study focuses on the measurement of spillover effects from macroeconomic factors to commodity volatility. It argues that such measurement is sensitive to volatility computation and to causality testing. To this end, I analyze two commodity data sets-gold and the Continuous Commodity Index (1969-2011), and twenty-four Dow Jones futures indexes (1991-2011)-and various macroeconomic indicators. I conclude that the macroeconomic factors that influence volatility generally depend on the commodity under consideration. I also explore whether commodities of the same class experience volatility shifts around the same dates, and find that this is not the case except for energy commodities.  相似文献

Biodiversity loss is a serious and ongoing global environmental problem. Economic instruments in biodiversity policies can contribute towards reconciling the conservation costs encountered at local level with the benefits of biodiversity conservation at higher levels of governance, from regional and national levels up to the global level. This paper outlines the theoretical foundations of fiscal transfers in conservation policies and also offers a concise account of existing international experience and future prospects. The recently amended Portuguese Local Finances Law (LFL) of 2007, with its groundbreaking new article on the promotion of local sustainability, is analysed in terms of the significance of fiscal transfers for municipal budgets. It is compared with its predecessor law, highlighting changes in fiscal revenues for selected municipalities in the country in relation to their designated conservation areas. The analysis shows that these ecological fiscal transfers can be significant for those municipalities with a large proportion of land under protected status. However, because it also introduces a considerable number of changes to the Portuguese fiscal transfer scheme, the ecological impact of the new LFL is difficult to grasp due to the presence of several crossover effects. The results obtained offer significant insights both for improving the Portuguese LFL and for designing new ecological fiscal transfer schemes.  相似文献

We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market.  相似文献

We examine the higher order properties of the wild bootstrap (Wu, 1986) in a linear regression model with stochastic regressors. We find that the ability of the wild bootstrap to provide a higher order refinement is contingent upon whether the errors are mean independent of the regressors or merely uncorrelated with them. In the latter case, the wild bootstrap may fail to match some of the terms in an Edgeworth expansion of the full sample test statistic. Nonetheless, we show that the wild bootstrap still has a lower maximal asymptotic risk as an estimator of the true distribution than a normal approximation, in shrinking neighborhoods of properly specified models. To assess the practical implications of this result we conduct a Monte Carlo study contrasting the performance of the wild bootstrap with a normal approximation and the traditional nonparametric bootstrap.  相似文献

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.
