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
Treatment of acute rheumatic-articular diseases with nabumetone
No full textTwenty patients, 10 males and 10 females, age range 32-76, mean age 57.80 years, with diagnoses of acute multiple joint disorders (9 cases), flare-ups of rheumatoid arthritis (4 cases), low back pain due to lumbosacral disc pathology (4 cases), osteoarthritis of large joints (3 cases), all with severe pain and corresponding functional limitation of the joints involved, were treated with a nabumetone preparation (1 g capsules; one capsule at night before going to bed) for 8-12 days. During treatment, symptoms subsided gradually with adequate recovery of joint function. Parameters concerning general tolerability did not reveal clinically relevant changes compared to baseline. Local tolerability was mostly satisfactory. Two patients complained of mild side effects (gastric pain and skin phenomena). Treatment was considered effective in 15 cases, scarsely effective in 4, and ineffective in on
Legumes in nutrition: understanding and applying scientific data today
No full textDuring the last decades, a huge amount of data has been made available to the scientific community and to the society about the effects of legume consumption on human and livestock nutrition and health. Attention was especially placed on grain legume as such or on single isolated components. As a consequence, legumes have been seen under a new light in Western countries. This positive perception also bathes legume byproducts.
It is now accepted that several molecules from le- gumes that have been described as toxic or unhealthy components may have positive functions if considered from a wider point of view. The role of some of these molecules have been reconsidered and their biological activities exploited in pharmacological, medical, cosmetic and food applications. Because of the vastity of the seed components and the many facets of the topic, two very different approaches are feasible to produce scientific results about the biological activities and the effects of legume-derived molecules.
The first one is to put forth the most prominent results about each legume class of molecules, namely proteins,
carbohydrates and non-nutrient compounds. The second one is to analyze separately every disease against whom legume seed components have been proved to be effective. Both have pros and cons.
The topic is hot and thus this area of study is rapidly expanding and new knowledge has been accumulating from day to day. The search for novel activities is pursued along with the elucidation of the underlaying molecular mechanisms of the observed effects, including intestinal absorption and bioavailability. One reason for this alive- ness is the burst of consumers’ interests toward nutritional/ dietary issues and the increased industrial expectations that ensue. Another reason is the growing availability of analytical in vivo/in vitro methodologies, which allow more accurate analyses even on minor food components or when the sample is very small. Searching for a direct cause/effect relationships between food components and bioactivities has been providing a deeper understanding of the effects themselves and of the related mechanisms of action. The role of synergic effects of several legume seed components is now emerging
[Efficacy and tolerability of nabumetone in the treatment of painful symptomatology of rheumatoid arthritis and osteoarthrosis].
No full textWe evaluated the effectiveness and the tolerability of a new non steroidal antiinflammatory drug (NSAID), nabumetone (1 g/daily for at least 8 days), in 20 patients (10 males and 10 females), 4 with rheumatoid arthritis and 16 with osteoarthritis. During the treatment we observed a progressive reduction of pain and swelling with improvement of articular movements. Our results showed an appreciable effectiveness of nabumetone treatment in 75% of patients. Excluding two patients with transient mild side effects (gastric and cutaneous symptoms), the tolerability has been satisfactory
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
Introduzione. (Saggio introduttivo)
No full textI linguaggi visivi proprii dell’espressione artistica rivelano, più di ogni altra forma di comunicazione umana, le profonde strutture della conoscenza. Le forme dell’arte traducono e condensano in oggetti concreti le sottili connessioni che legano pensiero, tecnica, scienza, estetica, cultura, etc. di ogni epoca e di ogni luogo. Ecco perché trasmettere il sapere per formare giovani consapevoli, dotati di capacità critiche, deve avvenire attraverso strumenti didattici scaturiti da nuovi più intensi scambi tra la scuola e le istituzioni preposte alla tutela dei beni culturali.
Nell’attuale momento di crisi della scuola e del sistema museale, pertanto, l’Anisa per l’educazione all’arte ritiene necessario ripensare il rapporto tra il museo e i suoi fruitori perché si possa rifondare, con una diversa ottica un sistema didattico basato su valori quali l’arte, la storia, la cultura del proprio territorio, al fine di rafforzare il senso di appartenenza al contesto sociale, per scoprire se stessi, il proprio passato determinato da dinamiche storiche scaturite anche dalla creatività dell’uomo.
Una nuova centralità nella didattica si chiede oggi ai musei: centri di produzione culturale per comprendere il passato proiettandosi nel futuro
From Medellín to Aparecida: the 'lesson' of a regional experience in searching for forms and styles of effective collegiality
No full textThe contribution proposes a historical excursus on the five general conferences of the Latin American episcopate from the constitution of CELAM, in Rio de Janeiro, in 1955, to the assembly of Aparecida, in Brazil, in 2007, with particular attention to the peculiarities of this singular experience of episcopal collegiality on a continental scale

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
