Effect of rearing system on carcass traits and meat quality of rabbits
No full textWe have developed a working protocol in order to evaluate the air contamination in different kinds of rabbitries for breeding rabbit used for experimental procedures using an easy instrument for sampling, the SAS® System (PBI International, Italy) and plates filled with different types of cultural media. [1‐2]
The two trials have been performed in a rabbit farm located in the NW of Italy. White New Zealand rabbits (NZR) were housed in two different rooms of the same building, with forced ventilation, one for does and one for fatteners. For air sampling we have used the SAS® System that is an impaction method that allows to enumerate the number of microorganisms directly in elevated convex plates filled with cultural media. A known volume of air is thrown onto a Surfair plate; then the sample is incubated depending on the microorganisms we want to isolate. The results are expressed as CFU (Colony Forming Unit)/m3.
During the first trial developed in the rabbit farm, the bacterial charge we have observed was always above 50 CFU/m3 of aspired air; Micrococcus luteus and Staphylococcus spp. were the most isolated microorganisms in both kind of samples. For fungi, 100% of plates were positive for environmental fungi and yeasts such as Aspergillus spp., Penicillium spp., Alternaria spp. and Rhodotorula rubra but their number remained under 50 CFU/m3. The percentage of dermatophytes isolated was between 50 and 70 and the only species identified was
Trichophyton mentagrophytes as in opened plates. [3] During the second trial, the microbiological results showed a total bacterial charge between 50 and 100 CFU/m3 air flow, using the SAS® System. On the contrary, the total fungal charge (environmental fungi and dermathophytes), keeps below 50 CFU/m3. These values could be considered low (50‐100 CFU/m3) and very low (<50 CFU/m3) with regards to the environmental risk according to the parameters supplied by the SAS System’s producer. The isolated microorganisms were Bacillus (100%), Alternaria (11,09%), Aspergillus
niger (36,12%) and Microsporum gypseum (41,67%). None of the bacteria/fungi that we have isolated was strictly pathogens.
So, the method we have applied for the evaluation of the microbial air quality allows us to obtain good and reproducible qualitative and quantitative results while opened plates allow only a qualitative results. Moreover, the SAS® System is portable and noiseless and it is optimal for sampling air in the nests and in cages or in a facility room.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
