Geoscience and Remote Sensing on Horticulture as Support for Management and Planning
Full text linkThe importance of horticulture around the large cities, called green belt (GB), or proximity food production area is related to its contribution to the provision of food as well as its role on social, cultural and ecological aspects. Geoscience and Remote sensing (GRS) are tools that should aid in gathering and updating the information to develop science-based management plans of this areas. Recently, the improvement in terms of spatial, temporal and radiometric resolutions has changed the performance and the approach to the horticulture remote sensing. In this work, we make a brief review on the literature exploring the use of GRS techniques in horticulture, and future trends in order to exploit the available techniques for efficient crop management in the way to improve territorial planning and management. Specifically we found a lack of academic production in this area. In addition we examine the importance of this landscape areas from different points of view (food security, health, ecology, etc.). A systematic revision of published studies on remote sensing on horticulture including different platforms, sensors and methodologies are briefly presented. Finally some aspect related with future trends are discussed.Fil: Marinelli, María Victoria. Comision Nacional de Actividades Espaciales.

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
Aportes de la geomática para el estudio de los entornos alimentarios vinculados a enfermedades cardiometabólicas: una revisión sistemática
Full text linkFil: Carrizo, Janet María. Universidad Nacional de Córdoba. Facultad de Ciencias Médicas. Escuela de Nutrición; Argentina.Fil: Mazzi, Gabriela Adriana. Universidad Nacional de Córdoba. Facultad de Ciencias Médicas. Escuela de Nutrición; Argentina.Durante las últimas décadas se observa un progresivo desarrollo en el
análisis y el manejo de datos espaciales, también aplicados al área de la salud, a
través de la Geomática. La decisión de investigar la Geomática en relación a las
enfermedades cardiometabólicas (ECM) está sustentada por ser éstas una de las
principales causas de morbi-mortalidad a nivel mundial.
Objetivo: Analizar sistemáticamente la evidencia científica relacionada con los
aportes de la geomática (sensado remoto, análisis espacial, sistemas de información
geográfica) al estudio de las ECM en relación a los entornos alimentarios.
Metodología: Se realizó una revisión sistemática de la literatura, usando diferentes
bases científicas online como Pubmed/Medline, Google Scholar, Lilacs y Scielo. Se
incluyeron aquellos artículos que contenían las palabras clave o una combinación de
ellas, durante el año 2015-2021. Se inspeccionó de forma objetiva y estructurada cada
artículo para determinar su validez y aplicabilidad. La calidad de los estudios incluidos
se realizó mediante la guía STROBE.
Resultados: Fueron analizados 14 artículos que explicitan el uso de tecnologías
geoespaciales para el estudio de ECM y sus factores de riesgo, realizados en
diferentes países y en relación al entorno, como así también sus factores de riesgo,
primando los estudios acerca de la prevalencia de obesidad y sobrepeso. Los SIG
(sistema de información geográfica) fueron los instrumentos más utilizados.
Conclusión: Las herramientas geoespaciales resultan eficaces en la recolección de
datos sobre factores del entorno que influyen en las ECM.Fil: Carrizo, Janet María. Universidad Nacional de Córdoba. Facultad de Ciencias Médicas.

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
