A survey of behavioural characteristics of pure-bred dogs in Italy
No full textThe selection of dog breeds for functionality has progressively lost its importance and behavioural attributes originally selected are often now considered problems in household contexts. This study investigated behavioural characteristics of the 49 most popular breeds of dogs in Italy. Questionnaires were sent to 112 Italian veterinarians and 56 non-veterinarians (trainers, behaviour counsellors and animal charity officers) who rated breed behavioural characteristics and compared the behaviour of males and females. Females were considered more trainable for obedience, more demanding of affection and more housetrainable. Males were rated higher than females for all other traits except playfulness and general activity. Principal factor analysis with varimax rotation generated two principal factors (labelled aggressivity and reactivity/immaturity) that accounted for 56% of the total variance. Nine breed groups with different behavioural characteristics were generated by K-means cluster analysis. These groupings had similarities with the groupings presented in the USA and UK, e.g. of the seven breeds rated as high in aggressivity in this study, five were rated high in all three countries, the Miniature Schnauzer was rated high for aggressivity in Italy and the US, but the Yorkshire Terrier was rated high only in Italy. These results provide further evidence of the need for care when transposing breed behavioural advice or treatments between countries.<br/

No full textLethal multiple pterygium syndrome (LMPS) is an
autosomal recessive disorder characterized by fetal hy
pokinesia wit]h consequent j oint contractures , pterygia
and intrauterine death . Retronuchal cystic hygroma
and hydrops are frequent as sociated findings [De Die
Smulders et al . , 1 9 90] . The pathogenesis of LMPS is
still unknown . An abnormal fragile collagen constitu
tion [Hartwig et al . , 1 989] and, more recently, a pri
mary aplasia of the developing muscle fibers [Moerman
et al . , 1 990 ] have been proposed .
We report on a case of LMPS in a 22 -week-old fetus
of healthy, unrelated parents with a history of fetal
death in 2 of 3 former pregnancie s and one normal

Familial congenital bicuspid aortic valve. a disorder of uncertain inheritance.
No full textCongenital bicuspid aortic valve (BAV) is one of the most frequent heart defects detected by echocardiographic investigation and necropsy (0.9-1% of the general population), but only 16 families with familial congenital BAV have been described up to now. We report on a family in which 4 members of two generations (2 brothers, 1 sister, and her son) are affected with BAV. The BAV mode of inheritance is discussed
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
