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
Social value of gender-neutral HPV vaccination in Italy
Get PDFOver the last decade, the main theme underlying my research in Health
Economics has been to estimate how the Value for Money of breakthrough
pharmaceutical innovation evolves with the availability of new clinical
information.
In 2008, Prof. H. Zur Hausen received the Nobel Prize for discovering the
cancerogenic role of HPV that he initially discovered in 1976. Following that, in
1989, Prof. Ian Frazer discovered the HPV vaccine that later in 2006 became
available globally. After the introduction of the vaccine, the clinical information
concerning the HPV changed considerably. At the time of its introduction, the
HPV vaccine was mostly used for the prevention of cervical cancer in women. A
few years later, the role of HPV as causative agent of gender-neutral cancers was
proved, namely anal, oral and head and neck cancers. In 2015, a new version of
the vaccine was introduced, active on a larger number of HPV strains causing
malignancies.
The five publications included for examination describe the historical
contribution of my research to the assessment of the economic value to the
payor (National Health System) of the HPV immunisation following the
availability of new clinical information. The setting is constant: the Italian
population covered by the NHS. The analytical approach varies according to the
availability of new inputs informing the economic models, aimed to
demonstrate the match between economic assessment and the availability of
new clinical evidence about the HPV immunization.
First, an original Markov model [1] demonstrated that vaccinating adolescent
girls against HPV would be beneficial and cost-effective as a public health
programme in Italy. To provide inputs to the model relevant to Italy, both terms
of the economic assessment were drawn from original NHS data that were used
in two publications. Specifically, a standardized time trade-off (TTO)
methodology was used [2] to quantify the utility loss in health states affected by
HPV- induced pathologies in Italy. On the other hand, an innovative Bound
Optimisation Model [3] was developed to determine whether the allocation of
resources was efficient for the prevention of HPV induced diseases ex-ante.
The outcomes of the cost-effective analyses [1,2,3] were included in the pricing
dossier leading to the initial reimbursement of HPV vaccine in Italy.
Furthermore, the BEST II study [4] evaluated the cost-effectiveness of universal
vaccination compared with selective vaccination of 12-year-old girls and the
economic impact of immunization on various HPV-induced diseases. In this
paper, a dynamic Bayesian Markov model was developed to investigate the
transmission of HPV virus in cohorts of females and males. As a result, genderneutral
HPV vaccination was found to be a cost-effective alternative when
compared with either cervical cancer screening or female-only vaccination.
Based on this new evidence, the Italian Government was the first among the G8
Countries to extend the HPV national immunisation programme to 12-year- old
boys (2017).
Finally, a systematic review of the extant literature [5] showed that the inclusion
of additional HPV types in the non-violent (active on nine strains of the virus)
vaccine offers a significant potential to expand protection against HPV infection.
The study was included in the pricing dossier for the reimbursement of the 9-
valent HPV vaccine as a replacement of the currently available quadrivalent
formulation
My main contribution to research has been the use of triangulation to augment
the internal validity of the outcomes. Triangulation has benefited investigators,
methods and data collection. In addition to my contributions to the
development of the overarching research plan, I also directly contributed to the
research output of each published paper submitted for examination.
My contributions reflect the expected research skills to be demonstrated upon

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
