This paper shows how relevant concepts in educational effectiveness can support public policy in order to improve the performance
of educational systems. Specifically, value-added indicators and the property of their stability over time is addressed with
reference to application to school/teacher improvement. Findings of a longitudinal study developed in Portugal concerning
primary education in mathematics are presented. Variance component models are fitted in order to obtain those indicators yearly
to class-school units. Results of this study reveal that value-added indicators can be a useful instrument for progressive
improvement in education, particularly in countries with high rates of student retention and evasion. The novelty of this
paper is to measure value added over a single year rather than all stage of schooling that refers to more than 1 year. 相似文献

In this article, public art is proposed as creative agency mobilized to form urban imaginaries. These alternate visions are largely facilitated by artists and art collectives using urban communities as performative grounds. These projects promote a view of art as an effective channel for ‘recentering’ — the identification of a multitude of centers that endlessly fracture and shift, very much resembling the nature of cities themselves. An alternate vision of the city through cartography informed by contrast, temporality and ephemerality is proposed alongside dominant representations of the city. Works by artists Alma Quinto, Mark Salvatus and Wire Tuazon are representative examples of such strategies. Diverse in tactics and platforms, defined by site‐specific mediations, the projects facilitated by these artists reveal the uneven conditions that beset Metro Manila and its outlying areas. Quinto's altered Urban Plan/Duyan is the result of her engagement with women in an informal settler community in San Andres Bukid, Manila, while Salvatus's web‐based Neo‐Urban Planner is an astute observation of the obsessive yet futile ordering of people and space by the state. Tuazon's Amphibian installation is a commentary on the encroachment of multinational interests in local communities. These interventions are foils to state‐ and private‐led urban development schemes. Their strength lies in their direct engagement with the sphere of public dialogue and self‐determination. These artistic practices and strategies are shaped by community interaction, revealing that meanings residing in urban forms are relentlessly negotiated by the numerous actors that inhabit the city. 相似文献

Whilst it is well established to think of international tourism as a type of exports, namely ‘home’ exports, the potential of tourism flows as an engine for fostering trade among countries is a poorly studied topic. In this paper, we show that this relationship can be studied at a very detailed level by exploiting the disaggregation of existing information on international trade and inbound tourism. We consider a sample of 25 countries belonging to the European Union, a region that has been interested by common shocks such as the establishment of the euro as the new currency for many countries and the liberalisation in the air transport market. We carry out a panel data analysis by means of which we assess whether international tourist arrivals by a given country activate additional exports towards the same country. We find not only that tourism can promote exports, but also that this effect displays important differences depending on whether or not consumption goods are considered. This finding is consistent with the idea that the experience of tourists in a given destination reduces the fixed costs of trade, thus facilitating access to the advantages of international trade for more peripheral economies. 相似文献

This paper makes an attempt to determine the factors influencing exchange rate and exchange rate uncertainty, as well as output and output variability. In the context of a small open economy under flexible exchange rates regime it is found that the level both of exchange rate and output is affected by monetary and inflationary shocks, as well as shocks in government spending, output, and trade balance. Further, the uncertainty of exchange rate and output is associated positively with the uncertainty of all shocks while the contemporaneous occurrence of selected shocks imposes either a positive or negative impact on exchange rate and output volatility. Finally, it is shown that the effect of the determinants either of exchange rate volatility or output volatility is very sensitive to the parameter values. 相似文献

Technological Specialization in Industrial Countries: Patterns and Dynamics. — This paper employs distribution dynamics and
patent data to study the empirical dynamics of technological specialization in industrial countries. Large countries spread
innovation activities across a wider range of technologies, and their specialization level in a field displays lower probability
to move around its initial level (country size effects). Mobility is high and asymmetric: it is difficult to improve specialization
in very disadvantaged technologies, while high comparative advantages revert towards lower specialization levels. These findings
undermine the theory of technological accumulation and path dependence, its implication of persistence in trade specialization
patterns and the effectiveness of targeted industrial and technology policies. 相似文献

This paper presents further evidence on the empirical regularity known as the "45-degree rule." Income and price elasticities of trade are estimated for 21 countries in a cointegration framework. More specifically, the autoregressive distributed lag (ARDL) modeling approach and the DOLS procedure are adopted to estimate the long-run structure. The empirical results confirm the existence of a systematic relationship between growth rates and income elasticity estimates: faster growing economies have high income elasticities of demand for their exports but lower import elasticities, which implies that faster growth can be observed without any marked secular trend in real exchange rates. 相似文献

This study describes the development and validation of an instrument to measure organizational learning. Starting out from a comprehensive analysis of the main organizational learning models in the specialized literature, the organizational learning scale in this study consists of 18 items forming five dimensions: the ontological levels of learning, modes of knowledge conversion, learning sub-processes, types of learning, and feedback and feed-forward flows of learning. A survey to large Spanish companies provides data from 167 companies. Confirmatory factor analysis tests the construct measurement model and validates the scale. The results of the study indicate that the scale satisfies the criteria for reliability, and validity. The exploratory factor analysis permits the identification of four factors which make theoretical sense: information systems, the existence of a framework for consensus, procedures for the institutionalization and broadening of knowledge, and forms of management and the genesis of knowledge. The new construct promises to be more comprehensive, integrative and eclectic than previous constructs, achieving its broad scope by incorporating a number of the main theoretical perspectives on the matter. For practitioners, the scale could form the basis of an auditing tool, as well as being a useful target for organizational change initiatives. 相似文献
