Contingent Valuation and Semiparametric Methods: A Case Study of the National Museum of Sculpture in Valladolid, Spain   总被引：1，自引：0，他引：1  

José Ángel Sanz  Luis César Herrero  Ana María Bedate 《Journal of Cultural Economics》2003,27(3-4):241-257

Research on cultural economics is very interested in the economic valuation of non-market goods, particularly in the field ofcultural heritage where contingent valuation techniques are currently being used with both parametric and non-parametric statistical methods to estimate the willingness to pay for cultural goods. In the literature analysed, the number of studies using semiparametric methods, however, is very limited. Our analysis is intended to help fill this gap by offering a parametric, non-parametric and semiparametric economic valuation of the National Museum of Sculpture (Museo Nacional de Escultura), located in Valladolid,Spain. In addition, we also gain insight on a controversial issue affecting most European museums, particularly those located in Latin countries: the role voluntary donations might play in the funding of public museums.  相似文献   

Collaborative digital government in Mexico: Some lessons from federal Web-based interorganizational information integration initiatives     

Luis F. Luna-Reyes  J. Ramon Gil-Garcia  Cinthia Betiny Cruz   《Government Information Quarterly》2007,24(4):808

The use of information and communication technologies in government has been characterized as one powerful strategy for administrative reform. From recent experiences around the world, it seems clear that in order to enjoy some of the greatest benefits of digital government, the integration of information across organizational boundaries is necessary. However, these digital government initiatives face additional challenges, since the required level of interorganizational collaboration and trust is often not supported by existing institutional arrangements, organizational structures, and managerial processes. In fact, many institutions and administrative structures found in government contexts offer incentives for single-agency work only, which produces stove-pipe systems. Based on an extensive case study in the Mexican federal government, this paper explores how certain institutional arrangements and organizational structures can enable or hinder cross-agency collaboration and consequently, interorganizational information integration.  相似文献

Gaining Visitor Consent for Research III: A Trilingual Posted‐Sign Method     

Lisa Sindorf  Joshua Gutwill  Veronica Garcia‐Luis 《Curator: The Museum Journal》2015,58(4):369-381

When studying museum visitors, researchers sometimes collect data by video‐ and audio‐taping large high‐traffic areas. In order to inform visitors that they are being recorded, researchers post signs in the area. This article describes the Exploratorium's efforts to design and test trilingual signs that would effectively inform visitors when video‐based research is in progress. Interviews with 255 adult museum visitors, conducted across six versions of the recording area's setup and signage, revealed several effective design elements. The posted sign was more noticeable and welcoming when it included a large headline, a realistic camera icon, and a colorful background. The most effective setup of the area contained many cues to videotaping beyond the large posted sign, such as visible recording equipment and small signs on exhibits and cordons. In the most successful trilingual setup we tested, 92% of visitors leaving the research area knew they had been videotaped.  相似文献   

Linking university and industry: An organizational experience in Mexico     

Mario Waissbluth  Gustavo Cadena  Jose Luis Solleiro 《Research Policy》1988,17(6)

This paper describes the experience gained in the Center for Technological Innovation since its creation three years ago within the National Autonomous University of Mexico. By offering the services of locating clients, drafting and negotiating contracts, providing specialized information services, and project follow-up, the Center pursues the establishment of effective ties between University projects and industrial production. In so doing, its staff informally assumes the critical “dgate-keeper” and “entrepreneur” roles, not easily accepted in other areas of the University.The main difficulties encountered so far have been in developing interdisciplinary projects, providing due academic recognition for technological activities and extending knowledge about innovation throughout the University. On the other hand, a great advantage is the interest shown by the academic community; likewise is UNAM's stability and autonomy, structural characteristics which have stimulated the development of technically sound teams over several decades. To date, the Center has provided support services for 125 projects and has participated in establishing 44 contracts between the University and industry.  相似文献   

Invention in the city: Increasing returns to patenting as a scaling function of metropolitan size     

Luis M.A. Bettencourt  Deborah Strumsky 《Research Policy》2007,36(1):107-120

We investigate the relationship between patenting activity and the population size of metropolitan areas in the United States over the last two decades (1980-2001). We find a clear superlinear effect, whereby new patents are granted disproportionately in larger urban centers, thus showing increasing returns in inventing activity with respect to population size. We characterize this relation quantitatively as a power law with an exponent larger than unity. This phenomenon is commensurate with the presence of larger numbers of inventors in larger metropolitan areas, which we find follows a quantitatively similar superlinear relationship to population, while the productivity of individual inventors stays essentially constant across metropolitan areas. We also find that structural measures of the patent co-authorship network although weakly correlated to increasing rates of patenting, are not enough to explain them. Finally, we show that R&D establishments and employment in other creative professions also follow superlinear scaling relations to metropolitan population size, albeit possibly with different exponents.  相似文献   

History of Spanish Mathematics Education Focusing on PhD Theses     

Mónica Vallejo-Ruiz  Antonio Fernández-Cano  Manuel Torralbo  Alexander Maz  Luis Rico 《International Journal of Science and Mathematics Education》2008,6(2):313-327

This article offers an overview of mathematics education in Spain, analyzing the production of PhD theses over the last 30 years. This period has been divided into four cycles that describe the evolution of Spanish research in the field of mathematics education, together with changes in university and social politics. This paper also includes a forecast of the number of theses that will be produced over the next 7 years, thus predicting the future progress and development of this area of research.  相似文献   

An adaptive controller for nonlinear teleoperators with variable time-delays     

Ioannis Sarras  Emmanuel Nuño  Luis Basañez 《Journal of The Franklin Institute》2014

In most real-life bilateral teleoperators the available physical parameters are uncertain and the communications exhibit variable time-delays. In order to confront these situations and only assuming that a bound of the time-delays is known, the present work reports an adaptive controller which ensures asymptotic convergence of both position errors and velocities to zero, provided that a sufficient condition on the control gains is met. Compared to previous related works that only treated constant time-delays, the stability analysis does not rely on the cascade interconnection structure of the local and remote nonlinear dynamics and the linear interconnection map. Instead, the paper employs a different Lyapunov candidate function that incorporates a strictly positive term, the local and remote position error. Some simulations, in free space and interacting with a rigid wall, and experiments, using two nonlinear manipulators, illustrate the performance of the proposed control scheme in the presence of uncertain parameters and variable time-delays.  相似文献
