Undercover journalism in social networking. Case study: Anna Erelle, in the bowels of the virtual terrorism
Get PDFEl auge de Internet en las dos últimas décadas ha tenido su impacto en el ejercicio de la
profesión periodística. En lo que respecta al periodismo de investigación, las redes sociales han
comenzado a proporcionar un nuevo escenario para la infiltración con fines informativos, tanto las
inmersiones parciales, que favorecen la toma de contacto del periodista con grupos de riesgo, como
las infiltraciones desarrolladas de manera íntegra en la red. El caso más sintomático ha sido el de la
periodista francesa Anna Erelle, que recurrió a la infiltración con un perfil falso en las redes sociales
para contactar con terroristas radicales islámicos. Su experiencia de inmersión se desarrolla
completamente en línea y consigue hacer creer al yihadista Abu Bilel que se iba a casar con él para
extraer información sobre IS y la captación de jóvenes para la yihad en las redes. A Erelle le asaltaron
las dudas éticas sobre el método utilizado pero la fragrante actividad delictiva del grupo disipó sus
planteamientos. El debate ético que siempre ha acompañado a la infiltración como método de
investigación periodística se intensifica en las redes, por su facilidad de acceso, más versátil de la red,
y su estructura descentralizada.The rise of the Internet in the last two decades has had a strong impact on journalistic
profession. In relation to investigative journalism, social networks have begun to provide a new
scenario for journalistic infiltrations and partial immersions, in which journalist use social networks to
get in touch with groups of interest, as well as complete immersions on line. The most symptomatic
case has been French journalist Anna Erelle’s infiltration using a false profile on social networks to
connect with radical Islamic terrorists. His undercover experience is fully developed online and she
manages to convince the jihadist Abu Bilel she would marry him to extract information about IS and
how yihadism recruit members through social media. Erelle hesitated about the ethics of how the truth
is revealed with this technique but flagrant criminal activities convinced her about its suitability. The
ethical debate associated to undercover journalism as an investigation method is more intense in
social networks because of their easy access, versatility and decentralized structur
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
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

Association of cervical artery stenosis with common cerebral microvascular lesions and coronary artery calcifications
No full textBackground A connection between cerebral white matter hyperintensities and coronary artery disease is widely discussed. Both conditions are more prevalent in the elderly. While white matter hyperintensities are often associated with small vessel disease, atherosclerosis is the primary cause of coronary artery disease. Methods We evaluated staging CT scans of the body and staging brain MRIs from patients with newly diagnosed malignant melanoma (without metastasis) between 01/01/2015 and 06/30/2023. CT scans were assessed for coronary artery disease using a modified overall visual assessment. Fazekas scores were used to evaluate the MRI for white matter changes. Additional clinical data were obtained from digital patient records. Results We analyzed data from 120 patients (57 females, mean age 68 years, standard deviation 14 years) and found a correlation between coronary artery disease and both age ( r = 0.48, α = 0.04) and Fazekas score (periventricular r = 0.46, subcortical and deep white matter r = 0.55). A linear model including age, coronary artery disease, diabetes and arterial hypertension served as a predictor for white matter disease and showed significant correlations. Adding (1) atherosclerosis as well as (2) carotid stenosis to the model resulted in (1) a slight decrease in significance and (2) the unmasking of a potential spurious correlation with carotid stenosis. Conclusion There is a significant correlation between white matter hyperintensities and both carotid stenoses and coronary artery disease. This finding is clinically relevant: in patients with white matter hyperintensities and coronary artery disease, carotid stenosis should be ruled out
