Le ragioni della democrazia: una congettura dimenticata a Pseudo-Senofonte, Costituzione degli Ateniesi 3,10
No full textthe paper argues that the manuscript text of Pseudo-Xenophon, Constitution of the Athenians, 3.10 δοκοῦσι δὲ Ἀθηναῖοι καὶ τοῦτό μοι οὐκ ὀρθῶς βουλεύεσθαι is not acceptable. The transmitted text gives a meaning that is inconsistent with what follows and with the text of the treatise in general. The author cannot say «It seems to me that the Athenians have a mistaken policy», since the treatise argues that the policies of the Athenians are efficacious. One should follow the conjecture first proposed by Faltin in 1872 and read δοκοῦσι δὲ Ἀθηναῖοι καὶ τοῦτό σοι οὐκ ὀρθῶς βουλεύεσθαι «It seems to you that the Athenians have a mistaken policy». The author is addressing an interlocutor, as in 1.8, 1.10, 1.11. The paper advances linguistic and philological argument in support of the conjecture
I giudizi su Cicerone nel Dialogus de oratoribus
No full textThis paper examines the attitude of the three main interlocutors of the Dialogus de oratoribus towards Cicero, highlighting how Tacitus reflects a series of current opinions on the crisis of oratory in the first century A.D., and shows himself mainly distant from Cicero and his formative and oratory model
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
Platelet monoamine oxidase molecular activity in demented patients
No full textBlood platelet monoamine oxidase activity, as well as other platelet enzyme activities, have been studied in several neuropsychiatric disorders in an attempt to identify biochemical markers of altered brain function. In this study, we determined both total and molecular monoamine oxidase activity in platelets derived from demented patients, which showed significantly greater enzyme activity than those of the controls. It therefore seems that the high degree of monoamine oxidase activity depends on the increased intrinsic activity of individual enzyme molecules. A significant positive correlation was found between monoamine oxidase activity and the severity of illness, which suggests that monoamine oxidase activity may be a state-dependent marker of neurodegeneration. These findings are discussed with reference to the central nervous system biochemical abnormalities of demented subjects: it may be that Alzheimer-type dementia involves some central biochemical changes that are reflected in certain peripheral tissues (e.g. platelets), or a systemic derangement that also affects the brain
Monoamine oxidase molecular activity in platelets of parkinsonian and demented patients
No full textPlatelet monoamine oxidase activity levels have been evaluated in several neuropsychiatric disorders, to identify biochemical markers for pathological brain functioning. In the present work, we assayed both total and molecular monoamine oxidase activity in platelets of parkinsonian and demented patients: both showed significantly higher enzyme activity values than healthy controls. Thus, high platelet monoamine oxidase activity levels seem to be related to an increased intrinsic activity of single enzyme molecules. A significant positive correlation was found between platelet monoamine oxidase activity and severity of illness in both disorders: monoamine oxidase activity, therefore, may be considered as a state-dependent marker for neuro-degeneration. Such findings are discussed with reference to central nervous system biochemical abnormalities in parkinsonian and demented subjects; it might be that in both Parkinson's Disease and in dementia of Alzheimer type some central biochemical changes are reflected in certain peripheral tissues (thrombocytes, for instance), or that a systemic derangement accompanies the cerebral involvement
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
La versione latina di Ciriaco Strozzi di Metaphysica Theta 6, 1048b18-35 e le sue fonti greche
No full textThe note scrutinizes the insertion of a Latin translation of Metaphysics Theta 6.
1048b17-36 in the 1562 Giunta Latin edition of the Metaphysics, the most influential
one during the early modern era. The passage cannot be found in the previous
Apud Iunctas edition of 1550. Its Latin translation, which is due to the Florentine
humanist Ciriaco Strozzi (1504-1565), does not seem to conflate exactly with any
extant manuscript of the Greek text, nor with its 1497 editio princeps in Aedibus

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
