OILANDSCAPES. Coupling ecological and social dimensions with oil infrastructures in Adriatic-Ionian region
No full textThe aim of the paper is to explore the potential of oil industry landscapes if ‘coupled’ with new socio-ecologic realms, for the definition of a innovative local development processes. It will lead the reader in understanding, firstly, the conceptual transition from previous ‘oil infrastructures’ to ‘oil meshes’, necessary to set the analytical and designing scale of our proposed OILANDSCAPES. Starting from the assumption that ‘oil infrastructures’ have always played an important role in the definition of the stratified territorial morphology and that can be considered as cultural heritage because of their socio-cultural values, in the first part the paper focuses on the definition of three kinds of oil landscapes: upstream, midstream and downstream landscapes. Then, it leads the reader’s attention on ‘oil infrastructures’ concept which is tightly related to an engineering approach in territorial planning. In the second part, the paper wants to introduce the suggested transition from ‘oil infrastructures’ to ‘oil meshes’ concept, supporting the idea that these three kinds of landscape have to be studied as a unique realm, so enlarging our point of view towards the territorial scale. After, the paper introduces the two current issues which are differently affecting oil industry on the Western coasts of Adrion region and on the Eastern ones:
the crisis of the downstream sector in the first case, and the increasing in exploration
and production oil activities in the second one. The effects of these local and regional dynamics will influence the territorial ‘oil meshes’ in their entirety. Therefore, ‘oil meshes’
are questioned to be responsive to a de-engineering reconversion process in one case and
to be sensitive to innovative planning tools in the other one. In the third part, two case studies, representative of the opposite outlined current trends, are identified thanks to their concentration of oil infrastructures: the South-Eastern Sicilian oil district (Gela-Ragusa- Syracuse) in Italy and the Myzeqe plain oil district (Fier-Patos-Marinza-Ballsh-Kucova) in Albania. The two oil regions, defined by a 130x130 km area, are comparatively analysed thanks to some thematic GIS cartographies. In the conclusion the paper evokes the socio- ecologic potential for local development processes of our shaped ‘oil meshes’ in defining new urban and ecologic centralities. Some results of the IDAUP PhD workshop in Tirana have been taken as examples to briefly sketch how we could imagine new possible scenarios for ‘oil meshes’ only coupling them with socio-ecologic territorial strategic vision. In this sense the paper proposes to ‘explore the new domain of OILANDSCAPES’
Integrating scheduling process for Italian ancillary services and balancing markets, considering uncertainties of RES-based DG
Full text linkThe proliferation and diffusion of Renewable Energy Systems (RESs), along with their associated uncertainties, have had an impact on the management of electrical grids and electricity markets. The focus of my doctoral thesis, carried out in collaboration with the Italian Transmission Operator (TSO) Terna, was on studying how the impact of RESs on the national transmission grid could be contained by reviewing the rules of the electricity market and the management of conventional thermal power plants.
The main issue examined was whether it was possible to devise a new algorithm for ancillary markets to better manage the evolution of RESs. The presence of RESs necessitates the implementation of measures for integrating scheduling processes for ancillary services and balancing markets, taking into account the uncertainties of RESs.
To achieve this goal, a comprehensive review of Optimum Power Flow (OPF) algorithms was conducted. Subsequently, a Projected Assessment of System Adequacy (PASA) simulation was carried out using the PLEXOS software to analyze how solar and wind generation could impact the choice of scheduling maintenance for conventional thermal power plants. This manuscript is divided into five sections and one appendix. The Introduction will provide an overview of the current state of the Italian electrical grid, outlining the different interconnections between Italy and neighboring countries and anticipating the main challenges that RESs could introduce into the operation of the electrical grid.
In Section 2, titled “The power flow algorithms in electricity markets”, the problem under consideration will be introduced by providing a description of the Italian electricity market. Section 3, titled “The state of art about the Optimum Power Flow algorithms”, will analyze the current state of OPF algorithms, distinguishing between classic OPF problems and stochastic OPF methods. Section 4, titled “Projected Assessment of System Adequacy (PASA)”, will describe the PASA simulation, how the model was implemented, and the results will be presented in Section 5, titled “PASA simulation results”. Finally the “Other research activities” writes in appendix will illustrate the
parallel activities that I have been conducted during this three year of work
Intersezioni urbane, Indagini e proposte per la rigenerazione urbana di un’area postindustriale
No full textIl progetto illustrato in questo libro è parte integrante di una ricerca che ha condotto alla definizione di uno studio di fattibilità per la rigenerazione urbana di un’area originariamente destinata, nella seconda metà del XIX secolo, a infrastrutture energetiche (ex officina per la produzione di gas e luce) e attualmente utilizzata come sede di un’azienda municipalizzata responsabile della gestione di un insieme di servizi di livello territoriale (distribuzione energia, energie rinnovabili, rifiuti, onoranze funebri) della città di Rovigo.
Coerentemente con la metodologia dello studio di fattibilità, nella ricerca sono state approfondite per la stessa area due alternative progettuali, veri e propri scenari di trasformazione urbana volti a definire possibili criteri di aggregazione di residenze, attività compatibili alla residenza (co-working, commerciale al dettaglio, ristorazione) e servizi locali a scala di quartiere (servizi socio-sanitari, spazi per giovani e associazioni)
Paesaggi culturali agroalimentari nel territorio cordobese
No full textTramite il concetto di “paesaggio culturale associativo”, la caratteristica unicità della realtà produttiva legata alla filiera alimentare di influenza italiana nei territori rurali cordobesi potrebbe divenire il legante intorno al quale costruire, attraverso una collaborazione formale tra attori pubblici e privati, un modello di sviluppo economico locale, in grado di configurarsi come distretto culturale dei paesaggi produttivi della provincia di Cordoba. I casi di Colonia Caroya e San Francisco, nella regione di Cordoba, mostrano gli effetti di tale sovrapposizione culturale italo-argentina all’interno della filiera produttiva alimentare dell’inizio del XX secolo
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
