No full textLightcurve and Rotation Period Determination for 5318 Dientzenhofer and 9083 Ramboehm
No full textPhotometric observations of the main-belt asteroids 5318 Dientzenhofer and 9083 Ramboehm were made in 2016 March and 2015 December, respectively. Analysis of the data found a bimodal lightcurve with a synodic rotation period of 8.062 ± 0.002 h for 5318 Dientzenhofer. A trimodal lightcurve with synodic period of 10.199 ± 0.004 h for 9083 Ramboehm was found to be the most likely solution
Observation on dogs found naturally infected with Hepatozoon canis in Italy
No full textClinical, haematological and laboratory findings recorded in 16 dogs
found naturally infected with H. canis in Italy were reported. Clinical signs
included depression, anorexia/dysorexia and weight loss (100 % each),
slight and serious lymphadenomegaly (37.5 % and 25 %, respectively),
fever (25 %), pale mucous membranes and pain on palpation of muscles
(6.25 % each). Parasitaemia values ranged from < 1 % to 70 %.
Haematological abnormalities were eosinophilia (87.5 %), leukocytosis
(43.75 %), neutrophilia (31.25 %), decreased values of HCT (31.25 %),
HGB and MCV (25 % each), monocytosis (25 %), lymphocytosis
(18.75 %), thrombocytopenia and lymphopenia (6.25 % each), as well as
normochromic anaemia, which was mild and microcytic (25 %) or serious,
non-regenerative and normocytic (6.25 %). Serum biochemical analyses
demonstrated increased CPK (25 %) and total protein (12.5 %), or low A/G
ratio (37.5 %) and hypoalbuminaemia (12.5 %). Serum protein electrophoresis
revealed β2- (100 %) and β1-hyperglobulinaemia (68.75 %), α1
(68.75 %) and α2-hypoglobulinaemia (25 %), and γ-hyperglobulinaemia
(37.5 %). Concurrent pathologies were E. canis or L. infantum (12.5 %
each)
Detection of Giardia assemblage A in cats in Florence, Italy
No full textIn the present study, the assemblage of Giardia isolates from stray and owned cats was investigated. Faeces were randomly collected from 27 cats, screened by microscopy and examined by molecular methods that included DNA extraction, small subunit rRNA gene amplification and DNA sequence analysis. Ten cats were found to be infected with Giardia and harbouring cysts belonging to the zoonotic assemblage A. The cat-specific assemblage F was not found. Such a high proportion of Giardia assemblage A in cats may pose for a different geographical distribution of assemblages in the world. These findings provide insights that may be useful to map the epidemiological risk of the infection worldwide, as this may be instrumental in safeguarding human health
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
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
