Expression of bovine viral diarrhea virus glycoprotein E2 as a soluble secreted form in a mammalian cell line
No full textBovine viral diarrhea virus (BVDV) membrane-anchored type I glycoprotein E2 is an ∼53-kDa immunodominant glycoprotein inducing the production of neutralizing antibodies in the animal host after natural infection or following immunization with live or killed vaccines. The E2 coding region lacking the transmembrane domain was constructed in a soluble secreted form (secE2) and expressed in the medium of a transiently transfected human cell line. The crude conditioned medium containing secE2 can be potentially employed to develop an enzyme-linked immunosorbent assay antigen for the diagnosis of BVDV infection or for vaccine purposes.

Admissions test for the degree course in veterinary medicine in Italy, 2005.
No full textIn Italy, access to the degree course in veterinary medicine is regulated each academic year by a government decree that sets the maximum student intake number for each of the 14 existing faculties. Candidates are selected by means of a multiple-choice test on the following subjects: logic and general knowledge, biology, chemistry, physics, and mathematics. Data for the 2005/2006 academic year are presented here. Overall, 4,495 candidates took the test and 1,415 (31.5%) qualified. The questions relating to physics and mathematics were more difficult than those in other subjects (p < 0.001). Logic and general knowledge was the subject in which candidates' knowledge was best. Separate data for each of the 14 Italian faculties are presented, along with the cut-off score for admission. In addition, a "difficulty admission index" has been calculated for each faculty centre

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
