Filone di Larissa - Testimonianze - Introduzione testo e traduzione
No full textIl lavoro costituisce una proekdosis delle testimonianze corredate da traduzione – non si può parlare di frammenti in senso proprio – su Filone di Larissa, vissuto tra il II e il I sec. a. C., filosofo della cosidetta Nuova Accademia e maestro di Cicerone. Nell’introduzione sono illustrati la vita e le opere e gli aspetti principali del suo insegnamento: gnoseologia, in rapporto alle precedenti posizioni scettiche assunte dall’Accademia a partire da Arcesilao, etica e retorica.

La "dolce ansa" del Nilo (Platone, Fedro 257d-e): un segnale di articolazione interno al testo platonico?
No full textL’articolo presenta una nuova esegesi e un’inedita interpretazione di un passo controverso e lungamente discusso del Fedro platonico (257 d-e). Si propone di intendere l’espressione “dolce ansa” presente nel passo come riferita al discorso tra Fedro e Socrate e, di riflesso, allo stesso dialogo platonico che proprio in quel punto presenta una ‘svolta’: dopo i discorsi sull’eros contenuti nella prima parte del dialogo, inizia qui infatti la discussione intorno alla retorica che occupa la seconda parte. In tal senso l’espressione“dolce ansa” rappresenta uno dei tanti ‘segnali di articolazione’ dei dialoghi posti da Platone all’interno degli stessi dialoghi, dei quali viene offerta qui una prima esemplificazione. This paper presents a new exegesis and interpretation of a much debated passage of the platonic Phaedrus (257 d-e). It proposes to interpretate the expression “pleasant bend” there present as referred to the conversation between Socrates and Phaedrus and, as a consequence, to the platonic dialogue itself which, just there, presents a turning-point: after the talks about eros in the first part of the dialogue, begins here the discussion upon the rhetoric which fills its second part. In that sense the expression “pleasant bend” represents one of the so many articulation’s signals placed by Plato inside the dialogues, of which a first exemplification is here offered.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Extraction of Bio-chemicals for Pharmaceutical and Food Industry from Myrocarpus frondosus, Robinia presudoacacia and Three Quercus Species
No full textThe amount of phytochemicals of interest for the pharmaceutical and food industry extractable from wooden biomasses largely exploited in the furniture and construction sectors as Myrocarpus frondosus, Robinia presudoacacia and three Quercus species were investigated. Adopting modified methanol based extraction protocols, particularly high amounts of antioxidant as ferulic acid 1.596 mg/g, syringaldehyde 0.74 mg/g, vanillic acid 0.327 mg/g and gallic acid 0.114 mg/g were extracted. (E)-coniferyl alcohol, ranging from 0.006 mg/g to 0.099 mg/g, was found in all the samples suggesting its use as an indicator of lignin degradation under alkali hydrolysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Analysis of bio-chemicals extractable from untreated wood waste
No full textGas-chromatography combined with mass spectroscopy was used to identify low-molecular weight organic compounds in two arboreal species. The woody extracts of seasoned heartwood of Quercus petraea and Myrocarpus frondosus, of interest to the parquet industry and the environmental field, were investigated. Different alkali extraction procedures were carried out using a CH3OH/H2O (1:1, v/v) solution. Particularly high extraction rates were obtained for antioxidant compounds such as ferulic acid (1.596 mg/g), syringaldehyde (0.74 mg/g), vanillic acid (0.327 mg/g) and gallic acid (0.114 mg/g). (E)-coniferyl alcohol, ranging from 0.006 mg/g to 0.099 mg/g, was found in all the samples, depending on the sample and extraction procedure, suggesting its use as an indicator of lignin degradation under alkali hydrolysis
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
