No full textDistribución social de los conocimientos de medicina tradicional en los Andes: Estudios de caso de Perú y Bolivia
No full textLos factores socio-económicos que influyen sobre los conocimientos de plantas medicinales de la población (personas no especialistas que se auto medican con plantas medicinales) han sido poco estudiado en la investigación etnobotánica. En este marco, el objetivo del trabajo de investigación fue analizar la distribución social del conocimiento sobre plantas medicinales en comunidades rurales de los Andes peruanos y bolivianos. Se realizaron entrevistas detalladas y ejercicios de listados libres en idioma Quechua con la ayuda de un intérprete local con 18 familias de un distrito rural de los Andes peruanos y 18 familias de una subcentral rural de los Andes bolivianos. Se recolectaron muestras botánicas de las plantas junto con los informantes en las dos áreas de estudios de caso. Un análisis cuantitativo de clasificación mostró que, en los dos estudios de caso, los vínculos de parentesco y la historia personal influye sobre las especies de plantas conocidas y usadas, en vez de otros factores como la edad, el nivel de educación, el estatuto socio-económico o la religión. El proceso de migración hacía los centros urbanos y las tierras bajas amazónicas, generalmente considerado como un factor importante en la pérdida de los conocimientos de medicina tradicional, solo tiene un impacto sobre el conocimiento de la población en el caso de familias que migran más de seis meses por año o de manera permanente. La migración no influye sobre los niveles de conocimientos de plantas medicinales ni sobre las estrategias terapéuticas de las familias que migran de forma temporal o por periodos más cortos de tiempo. Se demuestra que el impacto de factores socio-económicos externos que son generalmente considerados como la causa de la pérdida de los conocimientos de medicina tradicional en las altas tierras andinas es limitado. Además, los resultados de investigación implican que en zonas rurales donde la migración tiene un impacto sobre los conocimientos locales, la medicina tradicional podría ser mejor fortalecida si se trabaja estrechamente con familias y su red de parentesco extendida
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
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
