Dibattito anticipato e dicotomia risolti in Italia da un geologo-umanista
No full textIl capitolo ricostruisce la figura e il pensiero di Giuseppe De Lorenzo come anticipatore del dibattito sulle “due culture”, reso celebre da Charles Percy Snow nel 1959. Geologo e intellettuale poliedrico, De Lorenzo sviluppò una visione capace di coniugare scienza, filosofia e letteratura, trasformando la geologia in una “scienza filosofica” e intrecciando riflessione scientifica, sensibilità letteraria e ricerca spirituale. Attraverso l’analisi dei suoi scritti sul buddhismo, il contributo mostra come De Lorenzo abbia elaborato un modello unitario del sapere, in cui natura e spirito si rispecchianoThis chapter reconstructs the figure and thought of Giuseppe De Lorenzo as a forerunner of the debate on the “two cultures”, made famous by Charles Percy Snow in 1959. A geologist and multifaceted intellectual, De Lorenzo developed a vision capable of combining science, philosophy and literature, transforming geology into a “philosophical science” and intertwining scientific reflection, literary sensibility and spiritual research. Through an analysis of his writings on Buddhism, this contribution shows how De Lorenzo developed a unified model of knowledge in which nature and spirit are reflecte
Is the cold loop hysteroscopic technique a myometrial sparing treatment for placenta accreta residuals in a puerperal uterus?
No full textPlacenta accreta is a life-threatening obstetric pathology characterized by an abnormal invasion of chorionic villi into the uterine wall. The management represents a challenge for the gynecologist, especially in patients desiring to preserve their fertility. Several methods have been proposed to avoid hysterectomy. A case of a hysteroscopic conservative management with the cold loop technique in a puerpera with a large mass of placenta accreta residuals is described. The chorionic tissue was safely detached and it was subsequently removed by an electric cutting loop. Even in the absence of a clear cleavage plane, the thermal damage of surrounding healthy myometrium and dreadful complications as uterine perforation due to the electric cutting loop were avoided. The cold-loop hysteroscopic resection seems to be a safe and effective choice for the treatment of retained placenta accreta in patients desiring to preserve fertility. Moreover, it can also be proposed to patients who need to be treated immediately after delivery
Enseñar a des-naturalizar la mirada hacia la escuela secundaria : una práctica central en el proceso de formación de educadores

Instituto Superior de Formación Docente N° 41; Argentina.La siguiente experiencia se llevó a cabo durante el ciclo lectivo 2015, en el marco del Espacio de la Práctica Docente 1, del Instituto Superior de Formación Docente N° 41, de Alte. Brown, Pcia. de Buenos Aires, Argentina.
La pareja pedagógica se propuso trabajar con un grupo de jóvenes de 1er. año del Profesorado en Química, a fin de problematizar las prácticas de enseñanza naturalizadas en el nivel secundario, vinculadas al modelo tradicional.
Se parte del análisis de las biografías escolares de los/as estudiantes para reflexionar sobre las lógicas de funcionamiento institucional y las formas de enseñar que perduran en el tiempo, en contraste con los planteos renovadores del Diseño Curricular para la Educación Secundaria de la Pcia. de Buenos Aires. Se instala de este modo la tensión conservar-transformar como eje del trabajo de investigación anual, observando escuelas y entrevistando diversos actores institucionales.
A la vez, se presenta la secuencia didáctica a través de la que se abordan los propósitos planteados. Se destaca el aporte de los recursos del arte, en particular del lenguaje plástico como complemento para la expresión oral y escrita. Se ejemplifica a través de “las narrativas plásticas” creadas por los/as estudiantes para relatar las experiencias de aprendizaje del área, y de un “collage integrador”, como síntesis final del proceso de construcción colectiva del conocimiento
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
