Simulating Historical Flows And Connection. The Artistic Transfer During The 15th To 16th Century In The Iberian Peninsula.
The Late Gothic period (fourteenth-sixteenth century) was a phase of transition in Europe â with social, political, economic and cultural changes. Within this framework, Europe was the scene of a significant amount of mobility of artists that in some way materialised the production of architecture without borders: a "Pan-European style" (GarcĂa Cuetos, 2011) capable of reproducing and adapting models in different places. This paper will present the project ArTNet âAnalysing artistic transfer network. A social and spatiotemporal study of Late Gothic architectural production in the Iberian Peninsulaâ which was designed to identify, record and analyse artistic transfer network transcending the building scale to better understand the process of Late Gothic architecture production in the Iberian Peninsula. An integral view bringing together several factors is being studied by multiscale models, combining HGIS and Graph model, and analysis (such as SNA, spatial statistics, map visualisation and spatiotemporal analysis)
Achieving the state of research pertaining to GIS applications for cultural heritage by a systematic literature review
During the last decade, we have witnessed an increased interest in Geographic Information Systems (GIS), including the so-called âHistorical GISâ, 3D GIS heritage and its subcategory of âSDI for cultural heritageâ. Specific literature reviews, gathering and analysing the scientific production for Culture Heritage and GIS based research questions, are currently lacking. Therefore, the overall goal of this article is to provide an objective summary of the current state -of-the-art concerning how GIS has been used and what methods and analysis have been applied in the field of cultural heritage. In this sense, a Systematic Literature Review (SLR) of the literature on the application of GIS in cultural heritage is carried out. To do so, the WOS and Scopus databases were considered. The results show that the dominant application of GIS is in the realisation of inventory and cataloguing of archaeological and architectural heritage. As a result of the quantitative analysis, we also verify the principal sources in which most studies have been published, highlighting the "ISPRS Archives" with 14 publications, the "Lecture Notes in Computer Science" with 9, and "Proceedings of Digital Heritage" with 6 publications. These data show that the sources that most publis h mainly belong to the field of IT and Computer Science. In addition, the SLR shows that in the last three years there has been a greater tendency to use GIS to solve more specific problems of heritage through its use in conjunction with other tools such as BIM and photogrammetrySpainâs Ministry of Economy and Competitiveness HAR2016â78113-R HAR2016â76371-
Diasporic and Local Mainstream Media as a Tool for Intercultural Integration? The Case of Latin American Communities in Italy
In Italy, communication research on the impact of media on immigrantsâ integration dynamics has up until now privileged the sphere of national mainstream media. This paper takes into consideration the role of diasporic media as complimentary to perspective, by exploring the disposition of the two media fields towards the promotion of intercultural dialogue. In an attempt to assess whether there is in fact an intercultural media integration process occurring in both mainstream and Latin-America diasporic media players in Italy, this paper focuses on gathering evidence from the media pertaining to the society in general and from those created by and for immigrant communities. This evaluation aims to establish the degree to which majority and minorities take an interest in each other as well as the story telling they deploy or one another. Interculturalism and intercultural media integration are the main theoretical frameworks used to understand how intercultural dialogue is operationalized at the media level. Preliminary findings suggest a local mainstream media scene out of step with the de facto multicultural society, whereas only in some cases do Latin-American diasporic media demonstrate integrative potential capable ofâ bridging the gapâ with the host society rather than merely fulfilling its ingroup âbondingâ role
Innovation as a latent variable: an alternative measurement approach
In searching for improvements in the measurement of innovation, in this paper we suggest the idea of conceiving innovation as a latent variable or concept, i.e., one that cannot be accurately defined or directly measured. We propose the use of multivariate statistical analysis (a combination of cluster and discriminant analysis) as a possible way to develop indirect measures of innovation that are more appropriate to the intrinsically imprecise nature of the concept to be measured. In this way, the problem of using an ambiguous and subjective âinnovation definitionâ is limited, reducing measurement errors. We obtain an âinnovation intensity index,â which is a weighted average of ten different predictors.Measurement; Innovation; Multivariate; Discriminant analysis; Cluster analysis; Latent variable, innovation index.
A Regional Human Development Index for Portugal
In a report from 2008 the Organization for Economic Cooperation and Development came to the conclusion that Portugal is still a country very much marked by regional asymmetries and in need of better regional governance mechanisms and policies. In the face of these conclusions it becomes important to address the issue of constructing an index of regional development for Portuguese regions to better assess the evolution of the differential between regions. We propose a regional human development index for Portugal at the NUTS III level, based on the methodology of the Human Development Index (HDI) from the United Nations Development Programme (UNDP). Results show us a country that has most of the highest ranked NUTS III positioned in the coastline, although some interior NUTS III regions improve their relative positions in the ranking between 2004 and 2008. Additionally to the traditional dimensions of the HDI, we also added two dimensions, that we choose to include, given the main criticisms pointed in the literature to the HDI - governance and environment. Results show some significative differences when we add the environment dimension, but in terms of governance they don't change significantly.Human Development Index, Regional Asymmetries, Portugal.
A Benchmarking of the Undergraduate Economics Major in Europe and the United States
We compare the undergraduate Economics majors and their underlying structure in the top-ranked Economics departments of Europe and the USA, identifying the fundamental courses included in an Economics major in top-ranked universities. We further distinguish between those courses that are required and those that are usually offered as electives, finding striking differences between Europe and the USA, especially regarding the nature of the main electives offered. The insights from this comparative study may be useful for the ongoing restructuring of undergraduate Economics majors in European countries caused by the Bologna Process.
Historical SDI, thematic maps and analysis of a complex network of medieval towers (13th-15th century) in the moorish strip
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-4, 2018
ISPRS TC IV Mid-term Symposium â3D Spatial Information Science â The Engine of Changeâ, 1â5 October 2018, Delft, The NetherlandsThis work is part of an investigation into the use of GIS for the documentation and comprehension of medieval architectural heritage in the ancient Kingdom of Seville. The research was done in the framework of the project âSustainable guardianship of cultural heritage through digital BIM and GIS models: contribution to knowledge and social innovationâ, an interdisciplinary project focused on the applications of information technology in architectural heritage in Spain. The study case of this paper is located in the Guadalquivir valley during the period between 13th and 15th centuries. It concerns the Moorish Strip site, fortified by the Christian Kingdom of Castile with the aim of creating a barrier with the Moorish Kingdom. Its deteriorated state has led us to create a historical and spatial database in order to contribute to its conservation management plan. Apart from the historical documentation research and the data gathering, intensive fieldwork was also done to collect information about the buildings. In this paper we present a Historical SDI to investigate the hypothesis that the spatial patterns of the Moorish Band obey rules of âinter-visibilityâ control. Some analysis has been done on the site scale, such as: i) a thematic map of building material; ii) a spatiotemporal analysis; iii) the density of the distribution of towers over the territory; iv) a simulation of the territory visibility from the towers; v) the inter-visibility among towers; iv) thematic maps using attribute values. These analyses permitted us to highlight the need to create a preservation plan that should consider the network visibility system as an important value for heritage interpretation and knowledge.Spainâs Ministry of Economy and Competitiveness HAR2016â78113-
Geochemistry and risk assessment of street dust in Luanda, Angola, a tropical urban environment
A total of 92 samples of street dust were collected in Luanda, Angola, were sieved below 100 ÎŒm, and analysed by ICP-MS for 35 elements after an aqua-regia digestion. The concentration and spatial heterogeneity of trace elements in the street dust of Luanda are generally lower than in most industrialized cities in the Northern hemisphere. These observations reveal a predominantly ânaturalâ origin for the street dust in Luanda, which is also manifested in that some geochemical processes that occur in natural soils are preserved in street dust: the separation of uranium from thorium, and the retention of the former by carbonate materials, or the high correlation between arsenic and vanadium due to their common mode of adsorption on solid particles in the form of oxyanions. The only distinct anthropogenic fingerprint in the composition of Luanda's street dust is the association PbâCdâSbâCu (and to a lesser extent, BaâCrâZn). The use of risk assessment strategies has proved helpful in identifying the routes of exposure to street dust and the trace elements therein of most concern in terms of potential adverse health effects. In Luanda the highest levels of risk seem to be associated (a) with the presence of As and Pb in the street dust and (b) with the route of ingestion of dust particles, for all the elements included in the study except Hg, for which inhalation of vapours presents a slightly higher risk than ingestion. However, given the large uncertainties associated with the estimates of toxicity values and exposure factors, and the absence of site-specific biometric factors, these results should be regarded as preliminary and further research should be undertaken before any definite conclusions regarding potential health effects are drawn
Business Cycles, Core and Periphery in Monetary Unions: Comparing Europe and North America
We compare Europe with the USA and Canada as regards business cycle synchronization and core-periphery patterns. A long sample (1950-2005) makes it possible to study how these aspects have evolved over time. Results support the economic viability of EMU. Average cyclical correlations among European countries have risen significantly, reaching levels close to, or even higher than, those of North American regions. Applying fuzzy clustering to the analysis of core-periphery issues, we find Europe to actually outperform North America: the core-periphery divide is milder, and peripheral status seems generally less protracted.European Union, Canada, United States, Monetary Unions, Business Cycles, Fuzzy Clustering.
Services Innovation and Economic Performance An analysis at the firm level
We present a model that links innovation effort to economic performance, along the lines of the Crépon et al (1998) model. However, in contrast to Crépon et al, that analyze R&D intensive manufacturing sectors, the present application examines the relationship between innovation and performance for services sectors. This is relevant since much effort has been made to explore that relationship for manufacturing but very little is known about it in the case of services sectors. In trying to fulfill this gap the paper uses firm-level data from the Second Community Innovation Survey to estimate a simultaneous equations model for firms in ten services sectors in Portugal. The present model also differs from former approaches by the specific explanatory structure proposed to estimate the complex relationship between innovation and economic performance. Instead of estimating a direct link between innovation and labor productivity, three specific relationships were put forward. The first of them explains the innovation effort intensity (an input in the innovation process). The second one relates service innovation (an output of the innovation process) to effort intensity and to other explanatory variables. Finally, the third relationship links labor productivity to both service innovation and effort intensity considering also some other influences. Sensitivity analysis of the results to alternative estimation techniques was performed.Innovation and performance; Innovation in services; Technology; Service sectors; Labor productivity; CIS
