Cinema Demand in Spain: A Cointegration Analysis   总被引:4,自引:3,他引:1  
In this paper we explain the decline in cinema attendance in Spain since 1968. We use a cointegration analysis to estimate an individual demand function for cinema, with annual data and in terms of average attendance per inhabitant. We find that cinema is a luxury good and that its demand is elastic with respect to its price. We also show that television acts as a deterrent with regard to cinema attendance. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

Finding an appropriate temporary storage location for books and providing access to them is a significant challenge for libraries undergoing renovations. The current article describes the use of a document management company by an academic library to store 430,000 books for 8 months and provide a retrieval-on-demand service. Aspects covered include the selection of a commercial storage provider with its own retrieval service; details of the move to and from offsite storage; the integration of the service with library processes; communications and user feedback; book usage during the storage period; overall costs; and lessons learned from the experience.  相似文献

Future teachers must notice, navigate, and address ideologies in order to counter inequities in the literacy classroom. This article presents the findings of two teacher educators who have taken up the call to critically reflect on their own underlying beliefs and discourses regarding writing instruction. Through an education design framework, they analysed important components of the course, arguing for a higher degree of visibility of the ideologies and social forces that impact writing instruction. They found that despite encouraging a fairly complex and all-encompassing view of learning to write to the future teachers in their course, the creativity discourse was present passively and the socio-political was downright absent, despite clear social justice aims in the course. They discuss how well-established discourses can serve as gateways to embed the socio-political into the course and address more granularly the question of exclusion through selected mentor texts.  相似文献

The educational needs of eastern and central Europe can be met by distance education methods. The need to reform and to expand open and distance education possibilities led in 1990 to the founding in Budapest of EDEN, the European Distance Education Network. After 1990, the proponents of open and distance education were able to expand the scope of their activities as the result of expanding possibilities provided by the rapidly developing information and communication technologies. The pedagogical possibilities offered by these technologies are described with an emphasis on their democratizing tendencies, their ultimate inexpensiveness in terms of the total costs of different types of higher education, and their commercial possibilities. The setting up of the Distance Education Centre of the Technical University of Budapest is presented as a case study. Governments and institutions must find the best ways to use the information and communication technologies to integrate traditional higher education with open and distance learning techniques so as to offer the best possibilities at regional, national, and institutional levels.  相似文献

In distributed and cooperative systems, the network structure is determinant to the success of the strategy adopted to solve complex tasks. Those systems are primarily governed by consensus protocols whose convergence is intrinsically dependent on the network topology. Most of the consensus algorithms deal with continuous values and perform average-based strategies to reach cohesion over the exchanged information. However, many problems demand distributed consensus over countable values, that cannot be handled by traditional protocols. In such a context, this work presents an approach based on semidefinite programming to design the optimal weights of a network adjacency matrix, in order to control the convergence of a distributed random consensus protocol for variables at the discrete-space domain, based on the voter model. As a second contribution, this work uses Markov theory and the biological inspiration of epidemics to find out a dynamical spreading model that can predict the information diffusion over this discrete consensus protocol. Also, convergence properties and equilibrium points of the proposed model are presented regarding the network topology. Finally, extensive numerical simulations evaluate the effectiveness of the proposed consensus algorithm, its spreading model, and the approach for optimal weight design.  相似文献

This paper contributes to the ongoing debate on the impact of academic patenting on publishing and knowledge transfer. Drawing upon two separate surveys of academics, and their CV information, we provide empirical evidence for UK academics in engineering and physical sciences. The contribution of this paper is two-fold. First, our findings show that (the intensity of) academic patenting complements publishing up to a certain level of patenting output, after which we find evidence of a substitution effect. We also find weak evidence of important differences across scientific fields with the more basic-oriented fields showing indications of a crowding-out effect. Second, our analysis of the potential impact of patenting on knowledge transfer shows a positive correlation between the stock of patents and engagement in knowledge transfer channels. However, we find that a substitution effect sets in, indicating an inverted U-shaped relationship between patenting and several knowledge transfer channels.  相似文献
