Quantifying the impact of low carbon transition scenarios at regional level through soft-linked energy and economy models: The case of South-Tyrol Province in Italy
Low carbon transition agendas imposed by climate change claim for ambitious strategies grounded on non-biased information provided by energy and economic models. This is particularly relevant at local and regional scales, where environmental policies are practically implemented. To this end, this paper proposes a soft-linked model combining the EPLANopt energy simulation model with an empirical Input-Output model and applies it to assess the prospective impact of future scenarios in the Italian region of South-Tyrol. The proposed approach allows to perform scenario analysis of regional contexts with an accurate and physically detailed representation of the energy supply chain, while keeping track of the indirect and sector-specific economic and environmental impacts induced by a prospective policy action: the features and capabilities of the proposed approach are not fully covered by currently available methods and models. The EPLANopt model was setup and run for a selection of prescriptive scenarios, identifying optimal Pareto solutions in terms of minimization of economic cost of energy and carbon dioxide emissions. The results were then processed and incorporated into the Input-Output model, which allowed to evaluate the economy-wide economic and environmental impacts of such scenarios for different sectors. Results of the soft-linked model complement those of the EPLANopt model alone, as they reveal significant economic and environmental indirect effects that characterize the analysed scenario and are thus important to support decision-making
Life cycle assessment of sustainable concrete made with recycled aggregates
The results of an environmental study on concrete manufacture that follows the standard protocol of life cycle assessment are shown in this document. The study has been done for seven types of concrete: one conventional and six containing cement kiln dust (10%), marble sludge (10%) and demolition waste (10%, 80% and 100%) respectively, in partial or total substitution of natural aggregate. Six end of life scenarios have been proposed for the application of the life cycle assessment methodology. One of these is referred to the complete disposal of the waste obtained from demolition of studied concrete while in the others the treatment and recycling of demolition waste are analysed. In the latter cases the treatment plant location has been considered at different distances from the demolition site. The results show that, the life cycle of the considered concrete mainly impacts on greenhouse, summer pollution and winter pollution effects
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ARTISTE: An Integrated Art Analysis and Navigation Environment
The ARTISTE project aims to build a tool for the intelligent retrieval and indexing of high resolution images. European museums and galleries are rich in cultural treasures but public access has not reached its full potential. Digital multimedia can address these issues and expand the accessible collections. However, there is a lack of systems and techniques to support both professional and citizen access to these collections. The ARTISTE project will address professional users in the fine arts as the primary end-user base. These users provide services for the ultimate end-user, the citizen
21st-century alienation: From engineered humans to predicted humans
Emerging technologies seem to bring out unprecedented forms of human alienation, from the general issue of what we may define as engineered humans to the particular issue of what we may define as predicted humans. First, I shall reflect upon the way in which our language increasingly changes when we address our relationship with emerging technologies. More precisely, the change of our language shows a kind of optimisation that is taken to the extreme, starting with the optimisation of humans’ performances: the more engineered humans are (in that they identify their purpose not with feeling good, for instance, but with performing in faster and more profitable ways), the better they are (in that they measure themselves not against typically human values, such as feeling good, for instance, but against typically engineering values, such as efficiency). But a remarkable paradox emerges: the more humans work on optimising themselves, the more they (paradoxically) work on moving optimisation from themselves, i.e. their capabilities as autonomous humans (starting with self-perception and self-mastery), to technologies, i.e. ways of engineering, specifically automating, themselves. Second, I shall reflect upon the technological prediction of humans’ future as what may be thought of as the most extreme way to engineer them. Even though the cradle of Western culture, from scripture to mythology, continuously stresses that knowledge can be dangerous, specifically for humans, the history of Western culture coincides with the increasing effort to make knowledge the primary objective of human activities, from philosophy itself to science and technology. More precisely, the more technology develops, the more its primary objective is knowing our future, i.e. predicting our future, from our bodies’ performances to our minds’ performances. Are humans still free to determine their own future even surprisingly, i.e. against all odds
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
