Análisis descriptivo del proceso de desmonte y habilitación de tierras en el Chaco Argentina
Full text linkLa República Argentina, aún con las discontinuidades institucionales y altibajos de un país en vías de desarrollo, ha logrado crear y mantener estructuras institucionales reguladoras del patrimonio ambiental a todos los niveles de la administración pública (Morello y Rodríguez, 2007). Hacia fines del siglo xx, los eventos vinculados con el ambiente más relevante a nivel nacional y regional habían sido: a) la creación, entre 1950 y 1975 de grupos de trabajo en ambiente acuático y terrestre auspiciados y financiados por CONICET, INTA y las Univ. Nacionales; b) El creciente interés en el Gran Buenos Aires monitoreo de la contaminación aérea en áreas industriales (partidos Avellaneda, Lanús, Quilmes, La Matanza); c) la elaboración de propuestas de desarrollo sostenible en zonas áridas elaborados por grupos técnico-científicos del INTA y por lo menos 4 universidades: Bahía Blanca, La Pampa, Comahue y Cuyo; d) manejo de sobrepastoreo e incendios en ambiente serrano, Univ. de Córdoba, Univ. de Santiago del Estero; e) análisis de ambiente humano (Fundación Bariloche y desde 1972 la Secretaria de Ambiente y Desarrollo Sustentable (en adelante SAyDS); f) climatología ambiental (SMN, INTA, SAyDS, UBA); g) degradación de ambientes de bosques nativos (Univ. de Córdoba, UNLP, Univ. Misiones, Univ. Tucumán, Instituto Forestal Nacional); h) ambientes agroproductivos y agroecología (UNCO, UBA, Univ. de Cuyo y fundamentalmente INTA); i) ambiente urbano (UNNE, FADU-UBA, Univ. Rosario); j) ambiente de pastizales y arbustales (UBA, Univ. Río Cuarto, INTA, Univ. de Córdoba, Univ. de La Pampa, Univ. de Bahía Blanca); k) ambientes protegidos para conservación de la biodiversidad APN, INTA, SAyDS, Univ. de Cuyo, gobiernos provinciales en especial Santiago del Estero, San Juan y Chubut; l) ambientes de bosque nativo y plantaciones de exóticas (Univ. Comahue, APN); m) restauración de ambientes naturales y seminaturales (APN, UNLP, Univ. de Comahue, Univ. de Córdoba, Univ. Cuyo; Univ. de Tucumán); n) ordenamiento territorial y planificación ambiental, (UNNE, UBA, Univ. de Tucumán); o) estudio y control de procesos erosivos periurbanos y rurales (INTA, APN, UBA, Univ. de Bahía Blanca)...Fil: Morello, Jorge Helios.

Urbanization and the consumption of fertile land and other ecological changes: the case of Buenos Aires
Full text linkThis paper describes the conflict between agriculture and urban development in the Pampa Ondulada, the eco-region in which Buenos Aires is located, which is one of the world´s richest and most productive agricultural areas. It describes and analyzes the ecological changes brought about by urban expansion in peri-urban and rural areas between 1869 and 1991 and the form that these have taken. It also includes an analysis of the soil types where this expansion has taken place. The paper ends with a discussion of the lack of control over the continued expansion of the urban agglomeration, including that caused by the closed settlements now favored by middle and upper-income groups and the speculative parceling of land in advance of its development.Fil: Morello, Jorge Helios.

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
