Experience in designing and evaluating a teleconsultation system supporting shared care of oncological patients
No full textThis poster presents our experience in designing, developing and deploying a Web-based Teleconsultation System based on a Patient Centred Oncological Electronic Medical Record (PEMR) specifically designed to provide clinicians a cooperative work tool supporting the oncological patient management. An evaluation phase in a clinical setting was performed when the system was deployed in the hospitals. A second evaluation phase after two years of utilization is on goin
Exploiting clinical knowledge for supporting early diagnosis of melanoma
No full textNowadays there is an increasing availability of Information and Communication Technologies in the health care sector. This can represent a great opportunity to exploit Intelligent Data Analysis (IDA) in order to build effective tools for supporting medical decision-making.
In this paper we will describe our approach to the use of IDA technique in the dermatology domain. In particular we will show how we have handled the different knowledge and expertise of dermatologists in order to build an effective decision support system for early diagnosis of melanoma. The early diagnosis is a key feature for the successful treatmento of this disease, and it is still a difficult task.
Our approach was the development of several systems, each of those was "tuned" on the specific skill of the dermatologist, by first weighting more the dermatologist's miscrìlassified cases, and then combining the systrem outputs with the clinical diagnosis.
Our preliminary results show that, taking adequately into account different diagnostic skills of single dermatologists, it is possible to develop systems that could enhance the recognition of early malignant skin lesions; it means that the combination fo support system + dermatologist yields better results than the dermatologis
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
Information Technology in Pathology: from Telemicroscopy application up to date
No full textGiven the rapidly increasing number of ancillary technologies available to the medical community, there is a growing opportunity for their application, to address specific challenges. The development of new technologies for pathology such as robotic microscopes, and the availability of increasingly more powerful technologies for medical application is having profound impact in the research/diagnostic field in surgical Pathology [Wein_1].
In particular robotic microscopy in tandem with digital imaging stand for powerful technology to support and improve research studies and routine work in pathology field. Robotic microscopes let each microscope movement (x, y stage movements, objectives turret changes, auto-focus system, etc.) be controlled by local and/or remote computers and at the same time, images taken by video and/or photo-cameras mounted on the microscope, can be processed.
The first application area where robotic microscopy has been strongly engaged was teleconsultation (remote diagnosis as first or second opinion), as reported by a considerable number of recent studies [Wolf, Dunn]. The system that we developed in our lab as telepathology application for remote frozen section service was designed to address specific constraints given by local orography and regional network [Dem_1]. This system, called STeMiSy (Static TeleMicroscopy System), has been used between a district general hospital and the central hospital in Trento during the last year.
Moreover these technologies allow to manage histo-pathological glass slides as sets of digital data, thanks to completely automated systems, that acquire, store and manage digital images of the tissue on a slide. Digital representation of entire slide has been named in literature virtual slide [Wein_2][Saltz] and virtual case [Dem_2]. A virtual case is composed of a collection of digital images entirely representing a histological/cytological slide at all magnification levels, supplemented by all relevant clinical data. In comparison to glass slides it offers some advantages arising from its digital nature. Virtual case can be: a) reproduced in an indefinite number of identical copies stored in several different archives without any loss of sample technical quality in time, b) viewed and discussed simultaneously by many different distant users for different purposes without any times restriction, c) implemented with additional clinical and pathological data.
This kind of approach can be considered the common basis for multiple purposes in the fields of teleconsultation, education, research (quantitative pathology), and quality control and proficiency tests [Dem_3].
Doubtless information technology through the introduction of robotic microscope, digital imaging and data mining techniques is becoming a essential component in Pathology and will arise more and more importance in every Pathology department in the next year
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
