Ciclo de conversaciones antropologías del sur: Pedro Mege Rosso
No full textEn esta quinta entrevista del ciclo de conversaciones Antropologías del Sur, cuyo fin es revisar y pensar formas no hegemónicas de la disciplina, se presenta la trayectoria académica e intelectual de Pedro Mege Rosso (Viña del Mar, 1957), quien realizó sus estudios de antropología en la Universidad de Chile a fines de los años setenta, relatándonos las diversas experiencias de haber estudiado antropología en plena dictadura militar y cómo dicho contexto marcó la disciplina. La entrevista nos muestra los diversos lugares en que Pedro ha ejercido la antropología, desde sus inicios en el museo Precolombino, hasta su paso por distintas entidades académicas como la Universidad de la Republica, la Universidad Academia de Humanismo Cristiano, donde fue director de la Escuela de Antropología y la Pontificia Universidad Católica de Chile, donde actualmente es director del Centro de Estudios Interculturales e Indígenas (CIIR). En este recorrido, Pedro ha sido multifacético y se ha especializado en diferentes temáticas como son la lingüística, la etnolingüística, la semiótica, los textiles mapuche, la iconología, entre otros; y ha sido pionero en el desarrollo de la antropología poética, la antropología jurídica y la antropología visual en nuestro país. La entrevista y los relatos que de ella emergen son una invitación para conocer parte de la historia de la antropología en Chile, su presente y sus proyecciones

Eficacia acaricida del extracto vegetal MEGE contra los ácaros Tetranychus urticae y Panonychus ulmi (Acari: Tetranychidae)
No full text[ES] Este trabajo se enmarca en una de las primeras fases de un proyecto de investigación desarrollado en la empresa SEIPASA S.A. En este estudio se ha evaluado la eficacia acaricida de la microemulsión de extracto de ajo (MEGE) formulada por la empresa a tres dosis, 1,5, 3 y 4,5 L / ha sobre los ácaros Panonychus ulmi en cultivo de nectarino y manzano y Tetranychus urticae en berenjena y fresa. En los ensayos se ha comparado el plaguicida biológico con acaricidas comerciales y testigos sin tratar. El MEGE ha obtenido resultados positivos, con diferencias significativas respecto al testigo en todos los ensayos realizados, tanto en la evaluación del porcentaje de hojas ocupadas por ácaros como en el número medio de ácaros por hoja. En la mayor parte de ensayos, los acaricidas de referencia fueron más eficaces en reducir el porcentaje de hojas ocupadas por ácaros y en reducir su densidad poblacional que el MEGE, en cualquiera de las dosis empleadas. En los ensayos en frutales, con Panonychus ulmi, el formulado biológico no alcanzó una eficacia comparable a la del acaricida de referencia y su acción se manifestó tarde, al final del ensayo y tras tres aplicaciones del producto. En el caso de Tetranychus urticae, la eficacia del MEGE fue mayor en fresa que en berenjena, reduciendo en el primer caso las poblaciones de araña roja en un porcentaje similar al del acaricida comercial a las dosis intermedia y mayor ensayadas.[EN] The present work is part of a research project developed in the company SEIPASA S.A. This study evaluated the acaricidal efficacy of the garlic extract microemulsion (MEGE) at three doses, 1.5, 3 and 4.5 L / ha on the spider mites Panonychus ulmi in nectarine and apple trees and Tetranychus urticae in aubergine and strawberry. In the trials, the biopesticide was compared with commercial acaricides and untreated controls. MEGE has obtained positive results, with significant statistical differences with respect to the control in all the tests carried out, both in the evaluation of the percentage of leaves occupied by mites as in the average number of mites per leaf. In most trials, the commercial acaricides were more effective in reducing the percentage of leaves occupied by mites and their population density than MEGE, at any of the doses used. In fruit trials, with Panonychus ulmi, the biological formulation did not reach an efficiency comparable to that of the commercial acaricide and its action was delayed, at the end of the trial and after three applications of the product. In the case of Tetranychus urticae, the efficacy of MEGE was higher in strawberry than in eggplant, reducing in the first case the two-spotted spider populations in a percentage similar to commercial acaricide at the intermediate and higher doses tested.Muñoz Usero, M.

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
MEGE - An Educational Partnership Supporting Migrant Entrepreneurship
Get PDFThis article describes the implementation and lessons learned from MEGE—Multicultural Encounters, Growth and Entrepreneurship, an educational project aimed at better utilizing the expertise of migrant communities and international professionals in Finland, to foster entrepreneurship among those who migrate or return to the country from abroad. The 3-year project helped build bridges between communities by connecting different educational institutions and bringing together migrant communities and actors in the local entrepreneurship ecosystem. The resulting entrepreneurship training package was developed in cooperation with migrant participants and was offered free of cost to all international professionals, regardless of employment/residence status or cultural background. Key lessons learned suggest that the impact of such programs should be understood broadly, and that best results can be achieved by considering entrepreneurship education as both a service and a community. Such programs should contribute to participants’ business acumen and bring together migrants and members of local entrepreneurship ecosystems
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
Peritoneal perforation is less a complication than an expected event during transanal endoscopic microsurgery. experience from 194 consecutive cases
No full textBackground: Indications for transanal endoscopic microsurgery (TEM) have been extended to technically challenging tumors, which may be associated with an increased risk of peritoneal perforation (PP). The aim of the present study was to investigate the occurrence, management and outcome of PP in patients having TEM. Methods: All the patients who had TEM for rectal adenoma or adenocarcinoma in our unit were included. Patients in whom PP occurred (Group A) were compared to those without PP (Group B). Results: From 2007 to 2015, 194 TEM (116 men, median age 66 [range 21–100] years) were divided into Groups A (n = 28, 14%) and B (n = 166). The latter group included four patients, in whom a laparoscopy did not confirm suspicion of PP made during TEM. In 2 of 28 patients (7%), the diagnosis of PP was made postoperatively during reoperation for peritonitis. For the 26 other patients (93%), routine exploratory laparoscopy was performed with suture of the peritoneal defect on the pouch of Douglas in 24 cases and a rectal suture alone in 2 cases. Independent predictive factors for PP were: distance from the anal verge >10 cm (OR = 3.6), circumferential tumor (OR = 3.0) and anterior location (OR = 2.7). Hospital stay was significantly longer in Group A (7.5 [3–31] days) than in Group B (4 [1–38] days; p < 0.0001), whereas there was no significant difference regarding postoperative morbidity and recurrence rate. Conclusions: Our results suggested that PP is not a very rare event during TEM, especially in anterior, circumferential and/or high rectal tumors. Laparoscopic treatment of PP is feasible and safe. The occurrence of PP is not associated with poor oncologic results
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
