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

No full textVariations 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
Detection of chronic endometritis at fluid hysteroscopy
No full textAbstract
STUDY OBJECTIVE:
Chronic endometritis is a subtle condition that is difficult to detect; however, it may cause abnormal uterine bleeding and infertility. Few data exist about the appearance of chronic endometritis at fluid hysteroscopy and about the value of diagnostic fluid hysteroscopy in the detection of this condition. In our experience, at fluid hysteroscopy chronic endometritis is characterized by consistent association of stromal edema and either focal or diffuse hyperemia; in some cases, this finding is associated with endometrial micropolyps (less than 1 mm in size). This study attempted to describe diagnostic criteria for chronic endometritis at fluid hysteroscopy and assess the diagnostic accuracy of fluid hysteroscopy in the detection of this condition.
DESIGN:
Retrospective Study (Canadian Task Force classification II-2).
SETTING:
University hospital.
PATIENTS:
Nine hundred-ten women in whom hysteroscopy was indicated.
INTERVENTIONS:
Fluid hysteroscopy followed by endometrial biopsy.
MEASUREMENTS AND MAIN RESULTS:
Sensitivity, specificity, positive and negative predictive values, and accuracy of fluid hysteroscopy in the detection of chronic endometritis, based on the association of edema; hyperemia; and, if present, micropolyps were calculated. Based on the presence of hyperemia and edema, chronic endometritis was diagnosed in 158 patients (17.4%); in 61 patients (6.7%), micropolyps also were present. Histology confirmed the diagnosis in 101 patients (63.9% of positive cases at hysteroscopy) and was positive in 9 additional cases not detected by hysteroscopy. Chronic endometritis at histology was found in approximately 30% of infertile women and 35% of cases related to abnormal uterine bleeding. The sensitivity, specificity, and positive and negative predictive values of hysteroscopy for chronic endometritis based on detection of only hyperemia and edema were 91.8%, 92.9%, 63.9%, and 98.8%, respectively; the diagnostic accuracy was 92.7 %. The combination of hyperemia, edema, and micropolyps had sensitivity, specificity, and positive and negative predictive values of 55.4%, 99.9%, 98.4%, 94.5%, respectively, with a diagnostic accuracy of 93.4%.
CONCLUSIONS:
Fluid hysteroscopy is very reliable in diagnosing no inflammation, while detection of micropolyps is a very reliable sign of inflammation. When performing hysteroscopy for abnormal uterine bleeding or infertility, signs of chronic endometritis should always be sought
