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
L'assegnazione forzata dei crediti
No full textThe garnishee order or attachment of debts order is under the execution or enforcement of the judgment process as a final phase of the operation which started with the attachment of debts process. The nature and process of such an order lies in between both procedural and substantive law. The goal of this research is making a systematic reconstruction of garnishee proceedings: a procedure which states that a judgment creditor can recover the amount of the judgment debt from the owner of the judgment debtor s money. The concept of the attachment of debts order appears in our system as a legal means that more effectively allows creditors to achieve satisfaction of their rights. It has initially been considered the historical background and context of the garnishee order. Upon this contextual basis, the nature, function and effects of the order in general are examined more closely. The core part of this work analyzes in detail the garnishee order according to four distinct profiles. The attachment of debts is studied from the object of garnishee order point of view, according to specific aspects concerning the measure effects, with a particular emphasis on the dynamics of the relationship between actors involved in the procedure (judgment creditor; judgment debtor; garnishee). In order to identify the scope of the institute, a strong effort was made in conducting a research on specific practices. It has finally been established the fundamental features of the garnishee proceedings discipline
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
Postura cranio-cervicale ed organismica nel trattamento ortognatodontico delle disgnazie
No full textOBIETTIVI: Lo scopo del lavoro è mettere in evidenza l’intima correlazione tra le funzioni posturale, respiratoria e masticatoria dell’organismo e la morfologia dell’apparato stomatognatico, introducendo un concetto tridimensionale nell’approccio diagnostico e terapeutico in odontoiatria, considerando le tre componenti dentale-scheletrica-muscolare e compatibilmente con il range di tolleranza neuromuscolare.
MATERIALI E METODI: Il concetto di postura, non si riferisce ad una condizione statica, rigida e prevalentemente strutturale. Si identifica, invece, con il concetto più generale di equilibrio inteso come “ottimizzazione” del rapporto tra soggetto e ambiente circostante, cioè quella condizione in cui il soggetto stesso assume una postura o una serie di posture ideali rispetto alla situazione ambientale, in quel determinato momento e per i programmi motori previsti.
RISULTATI: L’ipotesi di correlazione tra postura e occlusione è giustificata dall’evidenza di rapporti anatomo-funzionali tra il sistema stomatognatico e le strutture deputate al controllo della postura. I risultati degli esami elettromiografici, kinesiografici e stabilometrici confermano la correlazione tra disgnazie ed il sistema neuromuscolare-posturale.
CONCLUSIONI: Gli obiettivi del trattamento includono un adeguato spazio per una normale funzione della lingua, una corretta dimensione verticale, una buona pervietà delle vie aeree nasali e una corretta postura cervicale e della testa. L’ortodontista non può accontentarsi dei soli parametri dentali e cefalometrici, ma deve trattare l’occlusione in base ad un equilibrio funzionale e dinamico di tutte le componenti dell’apparato stomatognatico in modo da creare condizioni adatte per una corretta sinergia tra estetica e funzione
The relationship of calbindin-containing neurons with substance P, Leu-enkephalin and cholecystokinin fibres: an immunohistochemical study in the rat thalamus
No full textIn the rat thalamus, immunoreactivity for the calcium binding protein calbindin (Cb) is mostly confined to neuronal cell bodies, sometimes revealing proximal dendrites, of the midline, intralaminar and posterior regions. Substance P (SP)-, cholecystokinin (CCK)- and Leu-enkephalin (L-ENK)-immunoreactive (ir) elements in the thalamus are fibre-like structures, intermingled with punctate elements probably representing axonal arborizations and their synaptic boutons. These peptidergic fibres are unevenly distributed in several thalamic domains, including the areas that contain Cb-ir neurons. The relationship between Cb-ir cell bodies and these three different peptidergic systems of thalamic innervation was studied with immunohistochemistry. Single-labelling experiments on adjacent sections and double immunostaining on the same section were performed. A considerable overlap between Cb-ir perikarya and SP-ir fibres was found in most thalamic nuclei. In particular, in the intralaminar nuclei and posterior compl ex, SP-ir punctate elements were frequently observed in close proximity to Cb-ir cell bodies and dendrites. On the other hand, no consistent topographical correspondence between Cb-ir perikarya and CCK- or L-ENK-ir fibres was evident. Altogether, the present data suggest a selective anatomical and, possibly, functional relationship between SP and Cb in at least a subpopulation of rat thalamic neurons
