Online resources for mathematics in the scientific virtual reference desk
No full textThe present work briefly describes the Virtual Reference Desk for mathematics elaborated during the time I worked at the CERN Library (European Laboratory for Particle Physics or Laboratoire européen pour la physique des particules) in Geneva. This instrument is dedicated to the CERN librarians, with whom I have shared important moments of my professional career. In particular, I would like to gratefully acknowledge their valuable co-operation and assistance during our time spent working together. The Web metasource is comprised of three directories, annotated and interrelated with dual application: The first is intended as a work tool for librarians working in mathematics libraries, but above all for librarians of high energy physics, who more often than not must turn to mathematics and the use of mathematical applications and models for the physical sciences and in particular particle physics. The second is an on-line resource for mathematics; that is, a Virtual Reference Desk for the community of mathematicians, with whom I have been collaborating for some twenty years at the University of Padova. The bibliographical instrument is born from the need to have at our disposal a scientific Virtual Reference Desk created according to the needs of those working in physics and mathematics libraries – a tool which is comprised of materials collected during years of work as much as material available on-line through the use of new technologies
Intervista con Antonella De Robbio, Responsabile del Settore Progetti e Biblioteca Digitale del Centro d'Ateneo per le Biblioteche CAB dell' Università di Padova e Referente per il diritto d'autore del Sistema Bibliotecario di Ateneo
No full textThe interview with Antonella De Robbio – manager of the “Project Sector and Digital Library” for CAB (Centro di Ateneo per le Biblioteche) of the University of Padua and copyright expert for Sistema Bibliotecario di Ateneo – was published in Pinali news.
Antonella De Robbio answered the following questions:
1) How to deal with the issues of author’s intellectual and economic rights in the context of scientific publishing and digital library?
2) What is the influence of the digital approach on the traditional ways to create and disseminate scientific communication?
3) In your opinion, can the experiences of University Press and the Open Archives represent the path to follow in order to overcome the paradox that a scientific author is also the user of his publisher?
4) Which are the outcomes of the fight between copyright and copyleft?
5) Which of these approaches are more suitable to label the metaphor of the “Society of Knowledge”
Literacy in Neapolitan Women's Convents in the Middle Ages and the Contribution of Digital Archives on Monasterium.Net
No full textAntonella Ambrosio seeks a viable way of carrying out research on this topic: the palaeographic analysis of the few available sources using a multidisciplinary approach that combines diplomatics, archival, and historical research. This approach ensures the appropriate contextualization of the source both historically and culturally. In "Literacy in Neapolitan Women's Convents: An Example of Female Handwriting in a Late Fifteenth-Century Accounts Ledger", Ambrosio provides a case study, analysing a single piece of handwriting evidence. The source is an accounts ledger from the Dominican convent of Santi Pietro e Sebastiano compiled in the second half of the fifteenth century, from 1485 to 1496. Using an analytical approach, the author has identified the handwriting of a particular (anonymous) nun from the convent; Ambrosio studies the script the nun used and formulates hypotheses about her cultural background and how she learned to write. The palaeographic analysis is fully contextualized thanks to the reconstruction of the old convent archive, a reconstruction helped by using digital technologies now accessible online at Monasterium.net. As Ambrosio's work demonstrates, technological advances may aid codicological work but careful palaeographic analysis is necessary to ascertain the participation of female scribes. In this case we witness the scribal development of a nun who began with a basic knowledge of writing and who went on to perform her practical task not well but adequately for the purpose
Literacy in Neapolitan Women’s Convents: An Example of Female Handwriting in a Late Fifteenth-Century Accounts Ledger
No full textThis paper is about a research i on the literacy and writing skills of Neapolitan sisters in medieval convents, due to the lack of adequate historical study of such nuns and the extremely complex nature of the documentary sources. Surviving evidence is scattered far and wide, and the old convent archives have been dispersed. Given the state of the survivals, Antonella Ambrosio seeks a viable way of carrying out research on this topic: the palaeographic analysis of the few available sources using a multidisciplinary approach that combines diplomatics, archival, and historical research. This approach ensures the appropriate contextualization of the source both historically and culturally. In ‘Literacy in Neapolitan Women’s Convents: An Example of Female Handwriting in a Late Fifteenth-Century Accounts Ledger’, Ambrosio provides a case study, analysing a single piece of handwriting evidence. The source is an accounts ledger from the Dominican convent of Santi Pietro e Sebastiano compiled in the second half of the fifteenth century, from 1485 to 1496.

How special are special sciences?
No full textThis essay deals with issues such as the unity of science, the autonomy of the special sciences, reductionism, physicalism, and the role that the concept of emergence plays in the debate about these topics. The author develops her point of view through critical examination of three significant perspectives held in contemporary epistemological discussion. Thus, according to Jerry Fodor, three theses are entailed by reductionism: the generality of physics, token physicalism, and reductionism itself (that is, the idea that every natural kind predicate of a special science is related to a natural kind predicate of physics). Fodor maintains that, in order to safeguard the autonomy of the special sciences, the reductionist thesis should be given up, as a consequence of the validity of the multiple realization thesis. Besides the generality of physics, only token physicalism is needed to guarantee both the autonomy of the special sciences and the unity of science on a physicalistic basis. However, reacting to Fodor’s thesis, Jaegwon Kim points out that adoption of token physicalism leads to consequences which are undesirable for the supporters of the autonomy of the special sciences. Moving from assumptions also shared by non-reductive physicalists, Kim argues that reductionism comes up again through “local reductions” and that, as a consequence, sciences such as psychology are devoid of any disciplinary unity. In the author’s view, Kim’s conclusions show that, in order to safeguard the autonomy of the special sciences, token-physicalism needs to be abandoned along with reductionism. In the context of present-day philosophy of science, John Dupre’s perspective is taken as an example of a position which gives up both of these conditions along with the unity of science thesis, as traditionally understood. The alternative to physicalism and to reductionism is an epistemological and ontological pluralism, according to which the different domains and levels of reality display autonomous characteristics and autonomous causal powers. But how should these latter be conceived? Does downward causation finds its place in the picture? The author’s aim in the final part of her essay is to show that Dupré’s allegiance to a liberalized form of empiricism is incompatible with an autonomous form of mental causation as well as with the most typical characteristics of the human being as a personal agent. The conclusion is drawn that in the particular case of psychology as the science of the mental, the last of Fodor’s conditions, the generality of physics, should also be rejected. Instead, a strong form of emergent property-dualism should, as a minimum, be accepted
Electronic Dictionaries for Information Retrieval, Automatic Textual Analysis and Semantic-Based Data Mining Software
No full textToday Lexicon-Grammar (LG) remains one of the most consistent
Natural Language Processing (NLP) approaches, especially for
Semantic-Based Data Mining (SBDM) and Semantic Web. Its main goal
is to describe all mechanisms of word combinations closely related to the
concrete use of lexical units and to sentence creation. Also, it gives an
exhaustive description of lexical and syntactic structures of several
languages. LG was set up by the French linguist Maurice Gross during
the ‘60s, and subsequently developed for and applied to Italian by
Annibale Elia, Emilio D’Agostino and Maurizio Martinelli. Its
theoretical approach is prevalently based on Zelig Sabbettai Harris’
Operator-Argument Grammar, which assumes that each human language
is a self-organizing system, and that the syntactic and semantic properties
of a given word may be calculated on the basis of the relationships this
word has with all other co-occurring words inside given sentence
contexts. Simple sentences2 are the minimal linguistic meaning structures
upon which LG founds its studies on natural language syntactic features.
In the last twenty years, LG has also reached important results in the
domain of automatic textual analysis and parsing with NLP-oriented
software such as INTEX3, UNITEX4, and more recently NOOJ5.

Monti is author of sections 1 and 2. Antonella Napoli is author of paragraph 4.2.
2 In LG, a simple sentence is formed by a unique predicative element (a verb, but
also a name or an adjective) plus all the necessary arguments it selects to achieve
acceptability and grammaticality. The study of simple sentences is completed analyzing
the rules of co-occurrence and selection restriction, which are distributional and
transformational rules based on predicate syntactic-semantic properties.

Morphometric analysis of intralobular, interlobular and pleural lymphatics in normal human lung
No full textIn spite of their presumed relevance in maintaining interalveolar septal fluid homeostasis, the knowledge of the anatomy of human lung lymphatics is still incomplete. The recent discovery of reliable markers specific for lymphatic endothelium has led to the observation that, contrary to previous assumptions, human lymphatic vessels extend deep inside the pulmonary lobule in association with bronchioles, intralobular arterioles or small pulmonary veins. The aim of this study was to provide a morphometric characterization of lymphatic vessels in the periphery of the human lung. Human lung sections were immunolabelled with the lymphatic marker D2-40, followed by blood vessel staining with von Willebrand Factor. Lymphatic vessels were classified into: intralobular (including those associated with bronchovascular bundles, perivascular, peribronchiolar and interalveolar), pleural (in the connective tissue of the visceral pleura), and interlobular (in interlobular septa). The percentage area occupied by the lymphatic lumen was much greater in the interlobular septa and in the subpleural space than in the lobule. Most of the intralobular lymphatic vessels were in close contact with a blood vessel, either alone or within a bronchovascular bundle, whereas 7\% were associated with a bronchiole and < 1\% were not connected to blood vessels or bronchioles (interalveolar). Intralobular lymphatic size progressively decreased from bronchovascular through to peribronchiolar, perivascular and interalveolar lymphatics. Lymphatics associated with bronchovascular bundles had similar morphometric characteristics to pleural and interlobular lymphatics. Shape factors were similar across lymphatic populations, except that peribronchiolar lymphatics had a marginally increased roundness and circularity, suggesting a more regular shape due to increased filling, and interlobular lymphatics had greater elongation, due to a greater proportion of conducting lymphatics cut longitudinally. Unsupervised cluster analysis confirmed a marked heterogeneity of lymphatic vessels both within and between groups, with a cluster of smaller vessels specifically represented in perivascular and interalveolar lymphatics within the alveolar interstitium. Our data indicate that intralobular lymphatics are a heterogeneous population, including vessels surrounding the bronchovascular bundle analogous to the conducting vessels present in the pleural and interlobular septa, many small perivascular lymphatics responsible for maintaining fluid balance in the alveolar interstitium, and a minority of intermediate lymphatics draining the peripheral airways. These lymphatic populations could be differentially involved in the pathogenesis of diseases preferentially involving distinct lung compartments

«Onzi tandu naro una limba mia»: Aspetti, temi e problemi della poesia in «limba» di Antonella Anedda
No full textL’articolo si propone di analizzare la produzione in lingua sarda di Antonella Anedda. A partire dalla raccolta Dal balcone del corpo si mettono in evidenza i principali snodi tematici connessi a questa particolare zona creativa della poesia aneddiana, relazionandoli con quelli maggiori presenti anche negli altri libri della poetessa. A conclusione del discorso si propone una interpretazione che indaga i motivi e le implicazioni intertestuali comportate dalla scelta del dialetto sardo, inteso dall’autrice come una lingua “ibrida” che di necessità si relaziona con il proprio vissuto esistenziale.
The article aims to analyze Antonella Anedda\u27s poems in Sardinian language. Starting from the collection Dal balcone del corpo, the article point out the major themes inside Anedda’s works and investigates reasons and intertextual implications involved in the choice of the Sardinian dialect, understood by the author as a "hybrid" language that necessarily relates to one\u27s own existential experience
