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
Maurizio Luisetti : in memoriam
No full textOn October 20, 2014, Maurizio Luisetti MD, Professor of Respiratory Diseases, University of Pavia, Italy,
passed away at his home in Pavia. He was 61 years old. We are all shocked and saddened by the
unexpected and untimely death of Maurizio, a good friend, a great researcher and an excellent doctor.
He was a very young researcher when, in 1985, he was appointed Head of the Biochemical and Genetic
Laboratory University of Pavia. He was among the founding members of Alpha One International
Registry, a member of the Coordinating Committee from 1997 to 1999 and a member of the Council from
2000. In 2010, Maurizio was appointed Head of the Respiratory Diseases Unit of Fondazione IRCCS
Policlinico San Matteo Pavia and Professor of Respiratory Diseases, University of Pavia
An upsteam enhancer and a negative element in the 5' flanking region of the human urokinase plasminogen activator gene
No full textThe 5' flanking region of the human urokinase (uPA) gene has been fused to the reporter chloramphenicol acetyl transferase (CAT) gene and its activity assayed by transfection in two human cell lines. Progressive deletions of the uPA regulatory region from the 5' end maintain a high level of expression provided at least 1870 (in A1251 cells) or 1963 (in HFS10 cells) nucleotides of the 5' flanking region are retained. A DNA fragment from -2350 to -1824 has enhancer properties, stimulating transcription of an enhancerless SV40 early promoter independently of orientation and distance. Internal deletions that still retain the enhancer element reveal the presence of negative cis-acting sequences between -1824 and -1572. Their removal, in fact, increases uPA transcriptional activity. Differences of expression of the uPA-CAT fusion genes in the two cell lines are also observed, indicating the presence of cell-specific cis-acting sequence
Il commento etimologico nelle voci del DESN, con un esercizio su strèuzo 'bizzarro'
No full textIl saggio chiarisce che nel commento alle voci del DESN è necessario esaminare le precedenti proposte etimologiche, anche quelle prive di fondamento proprio per mettere i nluce ch esi tratta di ipotesi non accettabili. Nel caso specifico sono qui esaminato ed escluse una serie di ipotesi che riguardano la voce strèuzo 'bizzarro'. Per questa voce si ipotizza qui una possibile provenienza dal russo
Pneumonia in frail older patients: An up to date
No full textDespite advances in diagnosis, antimicrobial therapy and supportive care modalities, community-acquired pneumonia (CAP) remains an important cause of morbidity and mortality, especially in patients who require hospitalization. Elderly patients with poor functional status are characterized by a higher risk of developing severe CAP, due to the frequent presence of underlying respiratory and cardiac diseases, alteration of mental status, and immunosuppression. In recent years, changes in the healthcare system have shifted a considerable part of older patient care from hospitals to the community, and the traditional distinction between community- and hospital-acquired infections has become less clear. Pneumonia occurring among outpatients in contact with the healthcare system has been termed healthcare-associated pneumonia. Older frail patients have a high frequency of aspiration pneumonia and pneumonia due to gram-negative bacilli and other multidrug resistant pathogens. The contemporary presence of renal impairment usually requires specific dose adjustment of antibiotic therapy, which may be toxic in this specific patient population. This review produces a summary of therapeutic recommendations on the basis of the most updated clinical and pharmacological data. © 2012 SIMI
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
