Full text linkEste trabalho tem como objetivo avaliar como a geografia territorial da Rota de Integração Latino-Americana contribui para a construção e a formatação de roteiro para o turismo de observação de aves, com enaltecimento de paisagens, de práticas culturais, de territorialidades e da sociobiodiversidade como um todo representadas na Rota. A área de estudo envolve municípios brasileiros, paraguaios, argentinos e chilenos atingidos diretamente por esse Corredor Rodoviário. O território abarcado pela Rota de Integração Latino-Americana é contemplado por vários ambientes propícios para a prática do turismo de observação de aves, em especial aqueles contemplados por Áreas Protegidas e arredores. O roteiro proposto percorre diferentes topografias, ecorregiões e ecossistemas singulares da América do Sul, tais como: Cerrado, Pantanal, Mata Atlântica, Chaco (seco e úmido), Yungas, Deserto de Montanhas, Campos de Altitude, Puna, Lagoas Altoandinas, Deserto e Vales desérticos, Costa do Pacífico e Tamarugales. Em cada localidade a biodiversidade compõe o espaço junto das práticas culturais e de territorialidades singulares. Tamanha riqueza e diversidade projeta esse percurso como um excelente roteiro para o turismo de observação de aves, pronto a ser percorrido, contemplado e apreciado em suas múltiplas possibilidades.The objective of this work is to evaluate how the territorial geography of the Latin American Integration Route contributes to the construction and formation of a route for birdwatching tourism, with the enhancement of landscapes, cultural practices, territorialities and socio-biodiversity as a whole represented in the Route. The study area involves Brazilian, Paraguayan, Argentine and Chilean municipalities directly affected by the Bioceanic Route Corridor. The territory covered by the Latin American Integration Route is covered by several sites suitable for the practice of birdwatching tourism, especially the protected areas in its direct and indirect influence area. The territory includes environments such as: Cerrado, Pantanal, Atlantic Forest, Dry and Humid Chaco, Yungas, Monte Desert, High Altitude Grasslands, Puna, High Andean Lagoons, Desert and Desert Valleys, Pacific Coast and Tamarugales. The great variety of landscape characteristics makes it an excellent route for ornithological tourism, ready to be explored and contemplated in its innumerable possibilities.Fil: Batista Mamede, Simone.

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
Comunidades de aves del bosque atlántico del Paraguay
Full text link[ES]La presente tesis ha sido desarrollada en uno de los últimos fragmentos mayores de Bosque
Atlántico del Paraguay. El Bosque Atlántico es una de las ecorregiones más importantes y
amenazadas en el planeta, quedando menos del 10% de su cobertura original. Esta tesis
tiene el principal propósito de aumentar nuestros conocimientos sobre los patrones que
caracterizan a las comunidades de aves del Bosque Atlántico, de manera a identificar
atributos importantes que deban ser considerados en los esfuerzos de conservación de esta
ecorregión. Entre agosto de 2004 y diciembre de 2006, se ha realizado un estudio de una
comunidad de aves de Bosque Atlántico en el Área de reserva para Parque Nacional San
Rafael. Dentro del estudio se realizó un relevamiento ornitológico de la reserva para
determinar su importancia para la conservación de aves a nivel regional, se analizó la
influencia de factores en la eficiencia del método de puntos de conteo utilizado para censar
comunidades de aves en el Bosque Atlántico, se describió patrones en la estructura y
organización de la comunidad de aves y se lo comparó con otras comunidades
neotropicales, y se analizó la influencia de variables estructurales de la vegetación en las

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
Status of the avifauna of San Rafael National Park, one of the last large fragments of Atlantic Forest in Paraguay
Full text linkWe provide new information on all birds known from San Rafael National Park, Paraguay. Ornithological records from the period 1997 to 2006 have been reviewed, adding 112 new species to the reserve's avifauna. We provide data on the presence of 405 species in seven basic habitats types, and on their relative abundance. Biogeographically, San Rafael has a mixed avifauna, consisting of 70 Atlantic Forest endemic species, two Mesopotamian Grassland endemics, and many with a wider distribution in South America. At least 12 species are threatened and 16 near-threatened, including important populations of Dryocopus galeatus, Platyrinchus leucoryphus, Alectrurus tricolor and Xanthopsar flavus. We provide brief comments on records of these 28 species within the study site. The avifauna of the reserve is one the most important in Paraguay, due to its high diversity and endemism. At the same time, it is under great threat and its viability is at risk unless urgent actions are taken. Fragmentation of the Atlantic Forest in Paraguay has left the San Rafael block almost totally isolated from other forests. The degradation of its forests through selective logging and clearance for agriculture still has severe impacts, as do hunting and frequent fires in grasslands and forests. Unfortunately, the legal situation of the National Park is extremely precarious, creating great uncertainty and problems for its conservation.Fil: Esquivel Mattos, Alberto.
