Metafisica e immaginazione. Da Suárez a Vico
No full textQuello fra metafisica e immaginazione è uno strano connubio. L’immaginazione è legata al corpo e ai sensi: come può far conoscere ciò che è incorporeo e sottratto alla percezione sensibile?
Eppure Vico nella Scienza nuova parla di una «metafisica fantasticata» dai giganti dopo il diluvio, intrisa di corporeità e immaginazione, contrapponendola alla metafisica astratta dei filosofi, colpevole ai suoi occhi proprio di aver smarrito il nesso con la fantasia e l’immaginazione. Unendo metafisica e immaginazione, Vico prende le distanze da un lessico filosofico che era anche il suo. Come giunge a questa posizione? Quali sono le sue condizioni di possibilità storico-filosofiche? Quali le implicazioni per una “scienza” della politica, della retorica, della storia?
Questo volume prova a rispondere a tali domande. Lo fa a partire da quel Francisco Suárez che Vico lesse con passione in gioventù, allargando poi l’indagine ad altri autori dell’età moderna: Locke e Spinoza, Galileo o Cartesio. Studiare il dibattito sul rapporto tra immaginazione, ragione e metafisica è dunque anche una maniera di riflettere su cosa sia stata (o sia) la modernità filosofica e sul modo in cui Vico vi contribuì o vi appartenne
Learning diaries and learning analytics, tools that can be integrated to understand study processes? Difficulty ratings and online activity tracking
No full textThe aim of this research was to analyze the contribution that a self-observation tool (the diary) can offer in a Blended University course with university students. A group of 67 university students observed their listening, reading and study behaviors by recording it in a lecture diary. These behaviors were also tracked and recorded as Log data by the Learning Management System used (Moodle). The research questions we tried to answer were about: a) the ability of students to judge the difficulty of the teaching material and to regulate their behavior on this judgment, assuming that a growth in the judgment of difficulty (indicated through the diary) should have corresponded to an increase in the number of performed activities (recorded via the logs); furthermore: b) they concern the possibility of relating effort to performance, assuming that an increase of the number of activities (recorded by log and declared through the diary) would have improved memory and learning. The main factor underlying the research can be defined as the consistency between student judgments and data obtained from the tracking of logs. Finally: c) we considered the relationship between profit and participation in presence or at a distance. Cues from self-observation and automatic recording of behaviors were then compared. The hypothesis was only partially confirmed by the results obtained. The ability to evaluate the different effort required by the proposed teaching material was problematic. The information contribution that can be obtained from the proposed tool for self-observation, the diary, is also under discussion, although it is useful in order to involve the end user in the evaluation and self-regulation process
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
Definizione di interventi per il controllo dell’inquinamento delle acque nel bacino urbanizzato del torrente Gravina
No full textIl presente articolo descrive uno studio finalizzato alla definizione di interventi per il controllo dell’inquinamento originato dagli effluenti urbani nelle acque del torrente “Gravina di Matera”. Nel bacino idrografico è ubicata un’importante area naturalistica, il “Parco della Murgia” (Directive 92/43/CEE “Habitat”, European Communities Natural Network); il torrente lambisce i “Sassi”, sito ampiamente noto per il rilevante interesse sociale, archeologico e religioso, e patrimonio dell’Unesco.
Lo stato naturale delle acque è oggi degradato in ampie tratti del torrente per la forte pressione antropica esercitata dalle aree urbanizzate delle città di Matera e di Altamura. Nei periodi di magra la portata idraulica è costituita prevalentemente dagli scarichi delle acque di drenaggio e delle acque reflue presenti sul bacino nelle aree urbane, industriali e commerciali.
In questo scenario, le potenzialità di un’azione pianificata di riqualificazione ambientale, correttamente impostata, divengono evidenti e consentirebbero, una volta concretizzate ed abbinate ad interventi anche di carattere architettonico, di prospettare un più conveniente uso dell’area eventualmente inserita in una struttura di parco urbano.
Lo studio, inquadrato in un piu’ ampio scenario di azioni tese alla tutela dello stato naturale del torrente nel bacino urbanizzato, è stato sviluppato attraverso un’attività preliminare di monitoraggio e di modellazione della qualità delle acque, condotta al fine di valutare lo stato ambientale, e su un’analisi tesa a verificare l’applicazione di sistemi di trattamento degli effluenti urbani, con particolare riferimento a processi naturali e terziari avanzati
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
