Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
O teorema de Morley
No full textEste trabalho tem como objetivo divulgar o teorema de Morley e suas aplicações. O teorema
afirma que os pontos de interseção das trissetrizes adjacentes dos ângulos interno de um
triângulo qualquer são vértices de um triângulo equilátero. Trissetrizes são semirretas que
dividem um ângulo em três partes iguais. Em um triângulo duas trissetrizes são adjacentes
quando partem de vértices opostos pertencente a um mesmo lado do triângulo e formam o
menor ângulo possível com este lado. Inicialmente faremos considerações sobre a origem da
geometria grega e o seu legado para a Matemática de ontem e de hoje. Destacaremos de forma
pontual alguns conceitos geométricos elaborados pelos gregos. Estes conceitos foram
organizados e publicado na obra, Os Elementos de Euclides. Abordaremos um dos três
problemas clássicos da geometria grega: a trissecção de um ângulo. Apresentaremos uma
solução para este problema usando a espiral de Arquimedes. Este problema motivou, ainda
que tardiamente, a formulação do teorema de Morley. Faremos um resumo da biografia de
Frank Morley, e em seguida apresentaremos algumas demonstrações de seu teorema. As
demonstrações apresentadas são elementares e podem ser assimiladas por alunos do ensino
médio. Ao final faremos outras considerações sobre o teorema, com a finalidade de mostrar a
sua abrangência, e apresentaremos algumas questões olímpicas relacionadas com o teorema
de Morley Palavras chave: Teorema de Morley. Trissecção. The present work aims to unveil the Morleys theorem and its applications. The theorem states that in any triangle the three points of intersection of the adjacent angle trisections form an equilateral triangle. Trisections are semi straight lines that divide an arbitrary angle into three equal parts. In a triangle two trisections are adjacent when they start from opposite vertices belonging to a same side of the triangle and form the smallest possible angle with that side. Initially we will present considerations on the origin of Greek geometry and its legacy to past and present Mathematics. In a timely manner we will approach some geometric concepts developed by the Greeks. Such concepts were organized and published in the work Euclid's Elements. We will approach one of the three classical problems of Greek geometry: the trisection of an angle. We will introduce a solution to this problem using the Archimedean spiral. Although belatedly, this problem led to the formulation of Morleys theorem. We will summarize the biography of Frank Morley followed by some demonstrations of his theorem. The demonstrations are elementary and may be assimilated by middle school students. Finally we will introduce other considerations on the theorem in order to show its scope and introduce some Olympic-related issues related to Morleys theorem. Keywords: Morleys theorem.

No full textA atividade aquícola, por se tratar de uma fonte de proteína de baixo custo, vem
ocupando seu espaço a cada dia. Com isso, há um aumento na utilização da água o
que tem gerado maiores perdas desse recurso natural, quando usado de forma
irracional. Variáveis do solo devem ser estudadas, como instrumentos para
minimizar essas perdas, favorecendo o uso racional desses recursos naturais. Esse
ensaio foi realizado em um Latossolo Vermelho Amarelo argiloso em fundo de
viveiro escavado para a aqüicultura e teve como objetivo avaliar três repetições da
permeabilidade do solo (k), e quatro repetições da densidade do solo (DS) e da
porosidade total do solo (PT) submetidos a diferentes níveis de compactação: solo
sem compactação (SN); solo compactado com três (SC3), seis (SC6) e nove (SC9)
passadas, respectivamente, do compactador de percussão e ainda três passadas do
compactador de percussão sobre a mistura de solo-cimento na proporção de 6,6%
(SCC). A testemunha foi o solo natural retirado em trincheira a 1,5m de
profundidade. Conclui-se que pelo teste Tukey (5%), as variáveis DS e PT
apresentaram diferença significativa entre o tratamento SN e os tratamentos SC3,
SC6, SC9 e SCC sendo estatisticamente iguais os tratamentos SC3, SC6, SC9 e
SCC quando comparados entre si; para a variável K, apresentaram diferença
significativa os tratamentos SN, SC3 e SC6 sendo estatisticamente iguais os
tratamentos SC9 e SCC; considerando o custo do tratamento SCC como 100%, o
tratamento SC9 foi equivalente a 7% desse custo, demonstrando sua viabilidade
econômica.Aquaculture activity, that s a source of protein with low cost, fills your space every
day. Thus, there is an increase in water use which has caused major losses of this
natural resource, when used irrationally. Soil variables should be studied, as
instruments to minimize these losses, encouraging the rational use of these natural
resources. This test was conducted in a Yellowish-red clayey Latosol in deep
Nursery excavated for aquaculture aimed to evaluate three repetitions of soil
permeability (k) and four repetitions of the density (SD) and total soil porosity (TP)
under different levels of compression: uncompressed soil (SN), compacted soil with
three (CS3), six (CS6) and nine (CS9) footfalls, respectively, of the compactor drum
and three footfalls of this compactor on mixture of soil-cement at a rate of 6.6%
(SCC). The witness was the native soil removed from the trench 1.5 m deep. Was
concluded that the Tukey test (5%), the variables SD and TP showed significant
differences between the treatment SN and treatments CS3, CS6, CS9 and SCC was
statistically equal the treatment CS3, CS6, CS9 and SCC when compared with each
other; for the variable K, showed a significant difference the treatments SN, CS3 and
CS6 was statistically equal the treatments CS9 and SCC, considering the cost of
treating SCC as a 100%, the treatment CS9 was equivalent to 7% of this cost,
demonstrating its economic viability
O rompimento dos laços de autoridade parental (pais e filhos perante o Estado Juiz)
Get PDFOrientador: Luiz Edson FachinDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências JurídicasA dissertação versa sobre a autoridade parental, termo que se preferiu em substituição a "pátrio poder", absorvido pela dogmática civil clássica do Direito Romano, mas que não corresponde ao sentido hodierno do munus que é atribuído aos pais. Rejeita-se a idéia de um poder que se exerce sobre os filhos, assim como se repele a redução de tal munus a um mero "dever" dos pais em relação à prole. No contexto da relação intersubjetiva entre pais e filhos é que se vai buscar o sentido e as novas dimensões da autoridade parental. A partir da análise de situações peculiares, quais se verifica o rompimento dos laços entre pais e filhos, ou sua distorção, são demarcados novos traços da autoridade parental, tendo em conta, especialmente, as radicais mudanças operadas com a promulgação da Constituição Federal de 1988 e do Estatuto da Criança e do Adolescente(1990). A reflexão desenvolvida toma a pessoa humana como critério último, fundamental e anterior ao Direito que regula suas relações e conduta. Ao adotar esta diretriz personalista, intenta-se proceder em nível teórico, à libertação da pessoa do conceito a que foi reduzida pela Dogmática Jurídica herdada do século XIX. Toma relevo, neste contexto, de um lado, a publicação do Direito de Família, com a criaçã de diversos mecanismos de intervenção do Estado e mesmo da sociedade civil numa esfera, antes, quase inatingível, com o fim de atender e resguardar o melhor interesse dauqeles que estão em fase de desenvolvimento, a infanto-juventude, e, de outro, a emergência da criança e do adolescente como sujeitos de direito. Estes significativos câmbios desafiam o repensar da relação paterno-filial. Sem a pretensão de reduzir a autoridade parental a um conceito, são apontadas, neste trabalho, algumas linhas de seu novo perfil.Abstract: The dissertation approaches the parental authority, term that was selected instead of "paternal power", taken by the classic civil dogmatic from the Roman law, but that cannot be related to the hodiernal munus which is attributed to the parents. It is not accepted the idea of a "power" that is carried out on children, as it is incompatible with the reduction of such munus to parents’ responsibility for kids. Through the intersubjective relationship among parents and children, it is proposed to look for the meaning and the new dimensions of the parental authority. Through the analysis of peculiar situations, which can be verified by the rupture of contact among parents and children, or through the distortion implied, new traces of parental authority are delimited, considering specially the radical changes caused by the promulgation of the Federal Constitution of 1988 and through the "Estatuto da Criança e do Adolescente" (1990). The developed reflection considers the human being first as a relevant criterion, fundamental and prior to the law that regulates its procedures and use. By adopting this personal perspective, it is expected to act, in the theoretical level, towards the person’s freedom of the concept that anyone was reduced due to the Dogmatic law inherited from the XIX century. It must be considered, in this context, the growing absorption of Family Law into the public sphere, through the creation of several intervention mechanisms of the State and also through the civil society which was almost intangible, aiming at supporting and protecting the best interest of those that are growing up, the infant and also, the importance of the teenagers’ growth as well as subjects of rights. These relevant changes challenge to reconsider a new relationship among parents and children. Without the pretension to reduce the parental authority to a concept, some characteristics of its new profile are pointed out in this work
Experiências sensoriais com crianças do berçario de um CMEI de Maceió/Al: a água como meio de descoberta do mundo na perspectiva das crianças muito pequenas
Get PDFThe present article was conceived through the experience provided by the supervised internship II that developed in Early Childhood Education, on the occasion, having as locus the Nursery of a CMEI in the city of Maceió in the state of Alagoas. This internship provided the experience with babies in the process of adaptation and socialization in the nursery, in the room and with the reference educator, as well as their insertion in society beyond the family scope. The aim of this article is to report on the possibility of how playing using the water element may be able to help young children in early childhood education, through their sensory perception and interaction with their peers, to appropriate the world that surrounds them, developing and improving the children's autonomy present in the games. The approached methodology was of a qualitative nature, with literary revision in order to promote critical comments, directed to the idea for which the theme is proposed, in addition to the systematic observation and reporting of the babies' behavior in the activities proposed in 5 Supervised Stage II. The theoretical basis was based on the authors CORSARO (2009); WALLON (2007) and VYGOTSKY (2008), as well as the Curricular Guidelines for Early Childhood Education in the Municipal Education Network of Maceió. This article intends to collaborate for the valorization of spaces in early childhood education that enhance children's autonomy in the perspective of building their own discoveries in the perception and appropriation of the world, emphasizing the basic importance of play as a pedagogical strategy for the significant development of young children in what their belonging to a social environment that requires decision-making and mutual collaboration from the subjects.O presente artigo foi idealizado mediante a vivência proporcionada pelo estágio supervisionado II que se desenvolveu na Educação infantil, por ocasião, tendo como lócus o Berçário de uma CMEI do município de Maceió do estado de Alagoas. Este estágio proporcionou a vivência com bebês em processo de adaptação e socialização na creche, na sala e com o educador de referência, bem como a sua inserção na sociedade para além do âmbito familiar. Tem-se como objetivo deste artigo relatar a possibilidade de como a brincadeira utilizando o elemento água, pode ser capaz de auxiliar as crianças pequenas inseridas na educação infantil, por meio de sua percepção sensorial e interação com seus pares, a se apropriar do mundo que as cerca, desenvolvendo e aprimorando a autonomia infantil presente nas brincadeiras. A metodologia abordada foi de cunho qualitativo, com revisão literária a fim de promover comentários críticos, direcionados a ideia para a qual o tema se propõe, além da observação sistemática e relatoria do comportamento dos bebês nas atividades propostas no Estágio supervisionado II. A fundamentação teórica teve como base principal os autores CORSARO (2009); WALLON (2007) e VYGOTSKY (2008), assim como também as Orientações Curriculares para a Educação Infantil da Rede Municipal de Ensino de Maceió. Este artigo pretende colaborar para a valorização dos espaços na educação infantil que potencializam a autonomia infantil na perspectiva da construção de suas próprias descobertas na percepção e apropriação do mundo, ressaltando a importância basilar da brincadeira como estratégia pedagógica para o desenvolvimento significativo das crianças pequenas no que tange seu pertencimento a um meio social que exige dos sujeitos à tomada de decisão e a colaboração mútua
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
