Comunicar con los visitantes: una nueva faceta profesional para los conservadores-restauradores

Heritage resources are more exposed than ever to visitors. For this reason, the transmission of cultural content is not enough: the present situation demands the inclusion of some messages able to foment a sustainable relation between the visitor and the resource. And this can best be achieved with the Preventive Difusion, a sensitizing strategy to inform and persuade visitors about the extreme fragility of the heritage resources. In addition, this strategy is a magnificent tool at the service of the corporate identity of the heritage resources and of the conservators: usually, preventive conservation actions and policies are not clear to visitors. But if they are included into the visit discourse, the public receive an accurate vi-sion of the efforts done in that sense, and it allows them to have a clear idea of these efforts, leading to the image that they have about the resource in question and, by extension, of their conservators.

“¿Cómo ha ido la Feria?” Estimación del impacto económico de acontecimientos turístos: tres estudios de caso

Los acontecimientos pueden contribuir al desarrollo turístico de una ciudad y beneficiar a sus habitantes y empresas. Sin embargo, para poder diseñar los acontecimientos correctamente, es necesario comprender qué características determinan su impacto económico. Esta investigación pretende contribuir a tal entendimiento mediante la estimación y comparación del impacto económico de tres acontecimientos. Para estimar el impacto económico adoptamos un modelo básico de tres factores: (1) número de visitantes por (2) gasto medio por turista por (3) multiplicador. Primero estimamos el número de visitantes particulares y profesionales mediante diversos sistemas de conteo, encuestas personales e información suministrada por el organizador de los eventos. En segundo lugar, obtuvimos los importes y componentes del gasto de los visitantes por medio de una encuesta; también contamos los gastos de organización de los eventos a partir de sus respectivos presupuestos. Y, tercero, utilizamos multiplicadores de tablas input-output para analizar el impacto de los gastos directos sobre la producción, el valor añadido y el empleo y su distribución entre sectores económicos. Además, calculamos y comparamos ratios de rentabilidad de los tres eventos y dimos recomendaciones para aumentar su impacto económico.

Simulating fuel consumption and vehicle emissions in an Australian context

Road transport is a major source of air pollution and greenhouse gas emissions around the world. There is an increasing interest in accurate information on local vehicle emission levels for policy development and sustainable traffic management. Previous studies have shown that emission predictions for the Australian situation need to reflect both the Australian fleet and driving behaviour to avoid unreliable outcomes. This paper discusses a new Australian vehicle emission software (PΔP) and a case-study where traffic simulation software (Aimsun) is combined with PΔP to demonstrate how consistent results can be achieved for the Australian situation. The case-study is an Australian city modelled using the microscopic simulator to generate the required trajectory data of each individual vehicle for the emission model. The simulation results are used in a number of ways: to assess the impacts of urban driving behaviour on fuel consumption, to create maps showing where and when elevated emission levels occur and to compare results with another program (COPERT Australia). The paper will also discuss where further research is required.
