Incidental findings in preoperative chest radiograph: is it an effective tool on patient outcome?
No full textClinical Data Management: A Web-based Electronic Folder for Oncological Patients
No full textBackground
Hospitals are taking advantage of Electronic Patient Report (EPR) technology to improve information sharing in the medical environment, thus providing better patient care and enhanced workflow efficiency. The aim of our work is to show a web-based EPR designed to improve information management in oncology.
Evaluation
We chose three main areas of interest (breast, liver, and colon cancer) by developing a user-friendly and interactive system following the detailed requirements of a multidisciplinary team of physicians. The result is a Web-based application that allows to share information stored in a central database containing a repository of clinical data and images. The system is accessible through dedicated web pages that are structured like conventional clinical records. Data can be retrieved from all local network connection points via a common web browser. In this way, information can be shared among different hospital departments; clients can log in to the system with personal accounts that give them different privilege levels. In the exhibit the accessibility of the database through mobile devices (such as the iPad2®; Apple Inc, Cupertino, CA) will be demonstrated.
Discussion
We developed an electronic patient folder that allows clinicians and radiologists to insert data and images into a remote database. In this way, each step of the clinical workflow can be organized for every patient, thus facilitating multidisciplinary case management. All web pages are built following strict rules for generation of structured data, which is essential for proper operation of the statistical data tools embedded in the system. The electronic folder also operates as a RIS add-on module, allowing to schedule follow-up appointments.
CONCLUSION
By utilizing a Web-based application, a low cost EPR has been created to facilitate clinical data sharing and to provide a cooperative working environment aimed at supporting the oncological workflow. Indeed, our electronic folder contains the complete clinical history of every patient, and therefore it can be useful for decision support and treatment planning, allowing users to get information quickly and concisely
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
