FAMULI SCHOLARIUM. NOTES ON LEGAL ANTHROPOLOGY OF UNIVERSITY STUDENTS BETWEEN THE LATE MIDDLE AGES AND THE EARLY MODERN AGE|FAMULI SCHOLARIUM. NOTE DI ANTROPOLOGIA GIURIDICA SULLO STUDENTE UNIVERSITARIO FRA BASSO MEDIOEVO ED ETÀ MODERNA
No full text«Famuli», that is domestic servants, represent a category of interest for common law given their ties with the domus and the family and, therefore, paternal power. However, they have little in common with the Aristotelian view of servants being «tools», more inherent to slaves. The domestic servant in fact, is characterised by features that provide it a degree of independence, for example the payment of a wage. The «famuli scholarium», however, constitute a separate subcategory, both in literature and legal theory. They take on specific roles and enjoy certain privileges guaranteed by the status of their masters, but they are also exposed to more precarious life conditions that often characterise the «ordo studentium». The starting point for the research was legal texts such as «Tractatus de servis vel famulis» by Ippolito Bonacossa, but in order to investigate the nature and understand the role of the «famuli scholarium», it is indispensable to pose questions on certain anthropological features of the daily lives of students and the reasons for their specific needs. Indeed, it is in the servants’ daily work with students that their role stands out
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
"Terremoti" originati dal transito di convogli metropolitani: strumenti di calcolo
No full textÈ stata pubblicata recentemente la norma UNI 9916, "Criteri di misurazione e valutazione degli effetti delle vibrazioni sugli edifici", che stabilisce in termini quantitativi la valutazione degli effetti delle vibrazioni sugli edifici. Fornisce anche una guida per la scelta delle metodologie appropriate per la misurazione ed il trattamento dei dati e identifica i fattori che influenzano la risposta strutturale dell'edificio alle vibrazioni. La necessità di analisi numeriche o sperimentali offre la opportunità di affinare strumenti già messi a punto per la progettazione in zona sismica e di rivisitare alcuni criteri di progettazione.
La diversità principale tra la problematica sismica e quella inerente le vibrazioni prodotte dal transito di convogli metropolitani riguarda il livello delle vibrazioni. Danni strutturali agli edifici attribuibili alle vibrazioni originate dal traffico sono rari. Perché possano arrecare danni strutturali è necessario che le vibrazioni raggiungano livelli tali da aver già causato disturbo agli occupanti; sono peraltro frequenti forme di danno "di soglia", sotto forma di fessure nell'intonaco, accrescimenti di fessure già esistenti, danneggiamenti a elementi architettonici. Il problema è particolarmente sentito nei riguardi della conservazione degli edifici monumentali e, come vedremo, nelle ristrutturazioni dei centri storici. In qualche caso, per fondazioni su terreni sciolti o di riporto, possono verificarsi fenomeni di compattazione del terreno e assestamenti che possono essere causa di formazione di cricche nei muri.
Nell’articolo si richiama un modello di calcolo noto nelle analisi di interazione suolo-struttura per la progettazione sismica, che fa capo al programma Flush, edito dalla University of California, Berkeley. Un’applicazione mostra alcuni insegnamenti che gli studi di ingegneria sismica possono offrire al problema del contenimento del livello di queste vibrazioni
TinyNET: A Tiny Network Framework for TinyOS: Description, Implementation and Experimentation
No full textIn this paper we present TinyNET, a modular framework allowing development and quick integration of protocols and applications for Wireless Sensor Networks (WSNs) in TinyOS. The motivation behind TinyNET is two-fold: on one hand it allows to adopt a divide-and-conquer approach in the development of any TinyOS application; on the other hand it provides a flexible administration of network protocols. As a sample development using TinyNET, we consider an environmental monitoring application, and test it over a floor-wide WSN testbed. Data are converge-casted toward a sink node, which gathers all data collected by the sensors. Routing toward the sink is achieved by means of a hop count (HC) based algorithm. Our framework also integrates support for the 6LowPAN standard (providing, e.g., per-sensor queries and pings). Thanks to TinyNET, s these messages will make transparent use of the underlying network protocols. Also, TinyNET transparently manages the network components and related messages, allowing different applications to share the same network stack; furthermore, it translates TinyOS interfaces so that any previously developed application can be easily ported. These features make it possible to have a global vision over any application, as well as to focus on each of its separate components
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
