Valutazione di due differenti tipologie di stress in ambito oncologico veterinario
Full text linkVeterinary oncology is a specialized branch in continuous growth thanks to the prolongation of the life of
affection animals, which frequently incur tumor pathologies. In addition, pets are increasingly regarded as
family members and for this reason owners have higher expectations of the veterinary services provided.
This document concerns the issue of stress in the field of veterinary oncology, analyzed on two different
fronts. The types of stress analyzed are: “oxidative stress” and the respective role in oncogenesis, but also
the “psychosocial stress” suffered by a group of dog owners for whom a tumor diagnosis was made.Oxidative stress is a complex and debated topic in the medical field and the techniques for its measurement
are different. In the present study the aim was to measure the redox state in canine cancer patients
through the use of the d-ROMs test and the BAP test. The values of d-ROMs and BAP were measured in 31
dogs with cancer and 28 healthy dogs. The age of all the subjects analyzed had an inverse relationship with
respect to the BAP value, but the group of sick dogs had higher levels, while d-ROMs did not differ between
sick and healthy. No differences were observed between local disease and metastatic or systemic disease,
and no differences were identified between dogs with carcinomas and dogs with lymphoma, but the mean
of the BAP values of these two groups differed significantly from the mean of the BAP values of the healthy
dogs. For both groups the BAP values were found to be within the normal limits. This result could indicate a
compensatory mechanism for oxidative stress. The average of the d-ROMs values, on the other hand, was
increased compared to the normal limits, probably due to a cumulative effect of oxidative stress with
advancing age and any other pathologies not easily diagnosed with the tests performed to select the dogs
healthy. In any case, the number of cases obtained is reduced and there was discrepancy between the
subjects regarding the tumor histotype, the clinical stage and the histological grade. Further studies, with
more patients, could help confirm a possible role of reactive oxygen substances in the development and
progression of tumors and the mechanisms through which the antioxidant barrier acts. Such studies could
also serve to investigate the prognostic value of d-ROMs and BAP and their role in monitoring antitumor
treatment strategies, whether or not associated with a possible therapeutic role of diet-supplemented
antioxidants.The second part of this document is aimed at investigating the stressful impact that the diagnosis of cancer
on a dog can have on its owner, through the use of the IES-R (Impact of Event Scale - Revised). The IES-R is
not a diagnostic tool, but is used as an indicator of a probable PTSD and is used on different occasions due
to its versatility. In the present study, the diagnosis of cancer on the dog, communicated to the owner, is
considered a stressful event. The people who completed the questionnaire were 21, 12 women and 9 men,
with an average age of 47 years. An IES-R score above 33 indicates a probable post traumatic stress
disorder (PTSD) and the mean score of the people who filled out the questionnaire was 42.7. Sixty-seven
percent of people had a score above 33, with an average of 67. People under the age of 50 had a higher
score than people over the age of 50. Women experienced more avoidance symptoms than men. Based on
these results, it is possible to suspect probable PTSD in most people who have received the news of the
disease in their pet and this reinforces the hypothesis that a pet is considered in all respects a member of
the family. Such findings can be of interest to mental health professionals, but also to veterinarians who
have to deliver bad news to the client. To the author's knowledge, there are currently no similar studies in
veterinary medicine, therefore it might be useful to expand the number of people who fill out the
questionnaire in order to study the many variables that can affect the assessment of people's mental state
and their adaptivity after receiving bad news from their veterinarian
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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.
