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
Parque Estadual da Serra Dourada : uma opção para o ecoturismo, seu cenário atual e perspectivas futuras
Full text linkMonografia (especialização)—Universidade de Brasília, Centro de Excelência em Turismo, 2004.Esse projeto de monografia analisou a viabilidade de implantação do ecoturismo no
Parque Estadual da Serra Dourada, situado nos arredores da Cidade de Goiás. Para tanto, se
fez necessário pesquisar junto aos turistas, sobre o interesse, para com essa atividade dentro
dessa unidade de conservação, bem como, realizar um estudo de percepção junto aos
moradores da cidade, como forma de verificar se são favoráveis a implantação da mesma,
nessa área. O projeto revela ainda a situação atual da área do parque a fim de propor
alternativas para o seu desenvolvimento.
Apresento também nesse projeto, a proposta de implantação do turismo regionalizado
para a Cidade de Goiás, tendo como estudo de caso, o “Circuito da Estrada Real”, programa
de turismo desenvolvido nos Estados de Minas Gerais, Rio de Janeiro e São Paulo. Dessa
forma, sugiro que o ecoturismo no Parque Estadual da Serra Dourada seja um dos produtos a
serem comercializados dentro de um roteiro, já existente, que é chamado de “Caminhos do
Ouro”.This project analysed the viability of introduction the ecotourism in Parque Estadual
da Serra Dourada, situated in the outskirts of Cidade de Goiás. So that, was necessary to
research with tourists, if they want to practice this activitiy inside this conservationt unity, as
well as, a perception study with the local residents, to check if they are favorable to introduce
this activity in this area. The project reveal this area present’s situation, and so that, intend to
offer some development alternatives.
I also present in this project, a proposal, of introctuction a regional tourism for Cidade
de Goiás, having with case study, the “Circuito da Estrada Real”, a tourism program that is
developed in the States of Minas Gerais, Rio de Janeiro and São Paulo. I suggest, that the
ecoturism in Parque Estadual da Serra Dourada, could be just one of the products to be market
inside an itinerary, that already exist, that is called “Caminhos do Ouro”
Paleogeographical interpretation of archaeological sites in sandy soils: the case of MT1 site in the basin of the middle Tocantins river (TO)
No full textFrom Geoarchaeology, discipline that results from the interface between Archaeology and
Geosciences, with an emphasis on Physical Geography and Paleogeography, as well as the
formation process of archaeological record, this research analyzed the natural factors that
conditioned archaeological site formation of Miracema do Tocantins 1 (MT1), currently,
under Cerrado domain. The site, seated on sandy sediments on the left bank, of the middle
course of Tocantins river, Miracema do Tocantins (TO), has been occupied since the
beginning of the Holocene, just over 10.000 years BP, with intervals of no occupation. This
study tested the idea that, the geological substrate of the site was a member of a supposed
Quaternary paleodunes field in the region, now mischaracterized by Cerrado coverage and
soil that it developed. The study started by the environmental characterization of the area,
with emphasis on compilation and adaptation of geology, pedology and geomorphology
information, followed by data collection in the field, which included the observation of the
landscape, the exposure and description of geopedological substrate, collecting material for
physical, pedostratigraphics and geochronological analysis, and the observation of the
sedimentary structures, to identify the site substrate and post-depositional processes related to
pedogenesis. The studies and analysis of pedologic materials indicated that the bedrock’s
natures is sedimentary petrographic, dated from the Lower Carboniferous, associated with a
wet environment sedimentation, of marine and fluvial facies; with absence of cross
stratification, typical of wind dunes; and the sandy pedologic material exhibits textural
homogeneity with medium sand fraction domain, is poorly sorted, of subrounded grains, subangular
and high sphericity, but asymmetrically positive pattern. The soil morphology and
composition exhibited progressive pedogenetic process without lithological or erosive
discordance, with grains exposed to solar radiation at about 9.100 years and 4.870 years BP,
according to OSL dating. In conclusion, the sandy material of the soil site comes from the
change of the source material from rocks inherited from Carboniferous formation, giving rise
to Quartzarenic Neosol, which was reworked during the Holocene by gravity displacement
(colluvial deposition) and low-power wind process (not formed dunes), covering the layers of
archaeological occupation dated from 10.530 years BP and 5.980 years BP.A partir da Geoarqueologia, disciplina que resulta da interface entre a Arqueologia e as
Geociências, com ênfase na Geografia Física e Paleogeografia, bem como, nos processos de
formação do registro arqueológico, esta pesquisa analisou fatores naturais que condicionaram
a formação do sítio arqueológico Miracema do Tocantins 1 (MT1), atualmente sob domínio
de Cerrado. O sítio, implantado sobre sedimentos arenosos na margem esquerda do médio
curso do rio Tocantins, município de Miracema do Tocantins (TO), foi ocupado desde o
Holoceno Inicial, há pouco mais de 10.000 anos AP, com intervalos de não ocupação. O
presente estudo testou a ideia de que o substrato geológico do sítio era integrante de um
suposto campo de paleodunas Quaternárias na região, atualmente descaracterizado pela
cobertura de Cerrado e de solos que nele se desenvolveram. O estudo iniciou-se pela
caracterização geoambiental da área, com ênfase na compilação e adaptação das informações
sobre a geologia, pedologia e geomorfologia, seguido do levantamento de dados em campo,
que incluiu a observação da paisagem, a exposição e descrição do substrato geopedológico, a
coleta de material para análises físicas, pedoestratigráficas e geocronológicas, além da
observação de estruturas sedimentares visando identificar o substrato do sítio e os processos
pós-deposicionais relacionado à pedogênese. Os estudos e as análises dos materiais
geopedológico indicaram que o substrato rochoso é de natureza petrográfica sedimentar
datado do Carbonífero Inferior, associada à sedimentação em ambiente úmido, de fácies
marinha e fluvial, com ausência de estratificações cruzadas típicas de dunas eólicas; e que o
material pedológico arenoso apresenta homogeneidade textural com domínio da fração areia
média, é mal selecionado, com grãos subarredondados, subangulosos de alta esfericidade, mas
de padrão assimetricamente positivo. A morfologia e constituição do solo exibiram processo
pedogenético progressivo sem discordância litológica ou erosiva, com grãos expostos à
radiação solar há cerca de 9.100 anos AP e 4.870 anos AP, segundo a datação LOE realizada.
Concluiu-se que, o material arenoso do solo do sítio é proveniente da alteração do material de
rochas herdadas das formacões Carboníferas, dando origem ao Neossolo Quartzarênico, o
qual foi retrabalhado no Holoceno por deslocamento gravitacional (coluvionamento) e
processo eólico de baixa energia (não formou dunas), soterrando as camadas de ocupação
arqueológica datadas de 10.530 anos AP e 5.980 anos AP
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
