Valuing cultural heritage: the social benefits of restoring and old Arab tower

2005

Abstract Cultural heritage protection is a key issue around the world today. In this paper, the contingent valuation method has been applied to obtain the social benefits that stem from the restoration of an old Arab tower in the Valencia Region of Spain. Due to a current and past lack of protection, the remains of this historic monument are few. Therefore, 252 individuals were randomly interviewed. On conducting our study we distinguished between low, average, and high consumers of cultural goods. Our main finding is that the mean willingness to pay (WTP) is considerably higher for the second group. To give further credence to this observation both parametric and non-parametric approaches …

Producción, comunicación, comercio y moneda en la Lusitania romana: el caso de la villa romana de Clavellinas (Torremejía, Badajoz)

2015

Las obras de la A-66 (Autovía de Extremadura) descubrieron un gran número de yacimientos arqueológicos que fueron excavados y documentados en su totalidad. La Villa Romana de Clavellinas es uno de estos ejemplos. Excavada entre junio del 2001 y enero de 2002, aportó gran número de estructuras y de restos materiales, suficientes para considerarla como un centro productivo rural romano. A su vez, también se documentaron un gran número de monedas con una cronología del siglo I d.C. al IV d.C. La catalogación de estas monedas y la valoración conjunta de todos los elementos exhumados nos permiten aproximarnos a la economía rural de la Lusitania Romana. When the A- 66 (Silver highway) was build, …

Is the NZEB Benchmarking Approach Suitable for Assessing Energy Retrofit Design?

2013

Currently, many effort have been done to enable energy saving issues in building design and many definitions have been introduced for most performing constructions based on energy balance between energy demand and supply. Recently, the Net Zero Energy Building theory has bypassed old Passive House concept but many questions still remain open. Present work aims to estimate how NZEB requirements matching could be affected by the choice of their definition and the choice of weighting factor system, to be count in the energy balance. NZEB concept is mainly referred to new buildings design. Its application to existing buildings is for sure an hard task provided the architecture and physical cons…

Environmentally Assessing Buildings Characterized by Complex Shape and Innovative Materials

2013

This paper addresses the emerging problem consisting in a correct energy and environmental evaluation of buildings belonging to the new architectural tendency. In fact, innovative buildings are often characterized by new materials that, not rarely, are not contemplated in current environmental databases. Moreover, unconventional shapes of these buildings could require further manufacturing processes that involve additional energy consumption not included in the commercial environmental database. Through the work a spotlighting of the problem is presented with reference to a real innovative building.

Improvement of Energy Efficiency for Indoor Lighting in a Big Shopping Center

2018

As the progressive diffusion of shopping centers in Italy, the paper analysis the potential energy savings in the indoor lighting plant, thanks to new technologies as LED lamps and Building Automation System. The case study, applied to a big shopping mall in the middle of Italy, shows great results, thanks to the high efficiency of LED technology, high number of operating hours and the implementation of a control system. An economic and environmental evaluation is reported.

Study of the performance of a resolution criterion to characterise complex chromatograms with unknowns or without standards

2017

The search for best conditions in liquid chromatography is routinely carried out with information provided by chemical standards. However, sometimes there are samples with insufficient knowledge about their chemical composition. In other cases, identities of the components are known, but there are no standards available, and in other cases the identities of peaks in chromatograms taken under different conditions are ambiguous. Most resolution criteria used to measure separation performance cannot be applied to these samples. In this work, a global resolution function valid for all situations was developed based on automatic measurements of peak prominences (area fraction exceeding the line …

The Evaluation of Social and Professional Life Competences of University Students Through Service-Learning

2021

The view previously held in the university regarding teaching-learning processes has changed significantly over the past few years. Undoubtedly, in the case of Europe, this change of pedagogical model has gone hand in hand with the creation of the European Higher Education Area (EHEA). Some of the pivotal areas of EHEA are the independent work of the individual student, the social dimension of learning, and the acquiring of skills, which are not reduced to the mere technical and/or subject matter knowledge. Generic competences and the so-called “soft skills” have also become important, given their significant contribution to the students’ academic, personal, social, and professional develop…

Student evaluations of the credibility and argumentation of online sources

2021

This study investigated upper secondary school students’ skills in evaluating the credibility and argumentative content of a blog text and a YouTube video. Both sources concerned child vaccination, the blog text opposing and the YouTube video supporting it. Students rated each source as credible, fairly credible or non-credible, justified their ratings, and analyzed the argumentation of both sources. Their justifications were analyzed for trustworthiness and expertise and their argument analyses for identification of the main position of the source and the reasons supporting it. Students’ justification skills proved fairly weak, and they also struggled with recognizing unbalanced argumentat…

DeepEva: A deep neural network architecture for assessing sentence complexity in Italian and English languages

2021

Abstract Automatic Text Complexity Evaluation (ATE) is a research field that aims at creating new methodologies to make autonomous the process of the text complexity evaluation, that is the study of the text-linguistic features (e.g., lexical, syntactical, morphological) to measure the grade of comprehensibility of a text. ATE can affect positively several different contexts such as Finance, Health, and Education. Moreover, it can support the research on Automatic Text Simplification (ATS), a research area that deals with the study of new methods for transforming a text by changing its lexicon and structure to meet specific reader needs. In this paper, we illustrate an ATE approach named De…
