Radiofrequency (SECCA® Procedure)
No full textMany resource materials exist for the physician or surgeon evaluating and managing
the patient with fecal incontinence. Much of the available information is
embedded in the context of an overall textbook or compendium of colorectal
surgery. There are a relatively limited amount of focused data for the practitioner
who wishes to become familiar or updated with the latest relevant diagnostic
and therapeutic information. Professor Mongardini is to be commended for
having assembled in a cogent, succinct, and imminently readable textbook all
of the abovementioned required details. He has selected 14 chapters each of
which was authored by between one and fi ve experts. This book commences
with a very surgeon-specifi c view of pelvic fl oor anatomy which I found readily
comprehensible and clinically relevant. The second chapter which I also
very much enjoyed reading is a description of physiology and physiopathology
again written from the perspective of the practicing surgeon. Studying this
chapter is an excellent prerequisite to digesting the subsequent four chapters
each of which delves into a different but important facet of evaluation.
Specifi cally, the chapters on endoanal ultrasound, magnetic resonance, anorectal
manometry, and electromyography are all very up to date, highly descriptive,
and again immediately useful in daily patient management. Reading these
four chapters allows one a comprehensive overview of the optimal available
current diagnostic tools. The remaining eight chapters describe virtually every
currently available therapeutic modality by which the practitioner can try to
assist the patient with fecal incontinence. The chapters include the gamut from
pelvic fl oor rehabilitation and radiofrequency tissue remodeling to stomas and
stem cells. In between these extremes are reviews of injectable and implantable
agents, sacral neuromodulation, the artifi cial bowel sphincter and the more
“standard” surgical therapies of sphincter repair, post anal repair, and muscle
transposition. The easy readability of the material in the textbook is further
complimented by the high-quality illustrations and photographs. It is clear that
each of the authors commands expertise in his or her respective chapter. It is
also quite apparent that Professor Mongardini edited the material to allow for
an easy narrative fl ow between chapters with minimal subject overlap but
excellent subject juxtaposition and interplay. I am very grateful to Professor Mongardini for having invited me to author this Foreword. I highly commend
this textbook to all physicians and surgeons who evaluate and/or manage
patients with fecal incontinence. This book shall certainly occupy a prominent
place in my personal library and will be enjoyed by all of my residents and
fellows.

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
