Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
TRIBUTAÇÃO E CONCORRÊNCIA: O PARADOXO DAS EMPRESAS PÚBLICAS
The State has, among its many ways of intervening in the economy, the constitutional prerogative to actively act as an economic agent. Through public entities, exerts function to meet standards of economic efficiency and also be aligned with the corollaries of social welfare. The porpoise of this article is to identify the paradox that arises when the tax burden on these entities is shown as costly as the incident on the private sector. And afford the taxes as a private company, when guided by social elements, the competitive element may be impaired. This scenario means that this bill is passed on to taxpayers.O Estado possui, entre suas diversas formas de intervir na economia, a prerrogativa constitucional de atuar ativamente como um agente econômico. Por meio de empresas públicas e sociedades de economia mista, exerce função de mercado visando atender padrões da eficiência econômica e, também, estar alinhada a corolários do bem–estar social. O problema surge quando a carga tributária sobre tais entidades mostra-se tão onerosa quanto a incidente sobre a iniciativa privada. E arcar com os tributos tal como uma empresa privada, quando pautada por elementos sociais, o fator concorrencial pode ser prejudicado. O problema é que a falta de produtividade gera perdas que são repassadas aos contribuintes
Social development and private health care system: three ways for success
A deep analysis in the Brazilian health care system shows how Government depends from private companies. State has the Constitutional duty to implement and develop the health care system, but its goal only is possible if Interact with the private sector. In this way, there are three ways for success: increase tax incentives, adopt an information economics and recognize health as a scarce resource. In fact, nowadays, private sector are assuming a duty without a public incentive policy, and it may impact in the sustainability of all health care system, as for private as for Government
Vigência E Prorrogação Dos Contratos Por Escopo Celebrados Com Entes Públicos
Brazilian Government is guided by the principles of legality and effectiveness. For example, there are the administrative contracts and tender procedures, according to the provisions of Law n. 8.666/1993. It happens that there is legislative omission about the scope contracts, in particular regarding the validity period and renovation. In this vacuum, Tribunals has followed the guidance of the Union General Attorney, which requires new bidding process whenever expires the contract. But that guidance can not be followed without restriction, under penalty of violation of effectiveness indicated in Article 37 of the Constitution. This occurs, for example, in hiring law firms and accounting advice in scope, with fees tied to the success. : A Administração Pública pauta-se pelos corolários da legalidade e efetividade. Assim o é com relação aos contratos administrativos e procedimentos licitatórios, consoante as disposições da Lei 8.666/1993. Ocorre que existe omissão legislativa acerca dos contratos por escopo, em específico com relação ao prazo de vigência e prorrogação. Nesse vácuo, a jurisprudência pátria tem seguido a orientação da Advocacia Geral da União, que exige novo procedimento licitatório sempre que vencido o prazo contratual. Ocorre que essa orientação não pode ser seguida de forma irrestrita, sob pena de violação da efetividade indicada no artigo 37 da Constituição. Isso ocorre, por exemplo, na contratação de escritórios de advocacia e assessoria contábil por escopo, com honorários atrelados ao êxito.
Agência nacional de saúde suplementar : o Estado e a saúde privada no Brasil
Não obstante o Estado deter o dever de prestar assistência universal, gratuita e integral à saúde do cidadão, o marco regulatório da saúde suplementar, consubstanciado pela Lei 9.656/1998, pautado por uma análise histórico-estrutural, permite concluir pela transferência de parte desta responsabilidade à iniciativa privada, em especial as operadoras de planos de saúde, que hoje possuem 48,7 milhões de beneficiários e detêm características ímpares. Desta forma que a avaliação do segmento deve pautar-se, a partir de sua ótica constitucional, pela relação estrutural existente entre operadoras de saúde e as políticas governamentais. Neste caminho, perceber-se que a constituição de uma agência reguladora e a forma de atuação da Agência Nacional de Saúde Suplementar (ANS) desvendam que o objetivo do Estado é desafogar o Sistema Único de Saúde (SUS) mediante a transferência de obrigações primárias às operadoras de saúde. Os beneficiários dos planos de saúde, mediante disposições regulatórias, passaram a se tornar suportados pela iniciativa privada. Ocorre que a substituição do Estado pela saúde suplementar sem considerar as peculiaridades do setor vem resultando no esgotamento da idoneidade financeira das operadoras de saúde, o que indica que o modo de regulação delineado para o segmento pode não estar em consonância com a otimização deste recurso escasso.Notwithstanding the State holds the obligation to provide an universal, free and full health service for the citizens, the actual regulatory act 9.656/1998 enforced by a structural analysis, emphasizes that the health service has been delegated to private, embodied in the health insurance, which currently has 48.7 million beneficiaries and has unique characteristics. Thus, the analysis of the segment needs to be viewed, first from the constitutional formalisms, and after by the relationship view the government policy. The establishment of a regulatory agency and the policies adopted by the Agência Nacional de Saúde Suplementar (ANS) reveals that the goal of the State is vent the public health system (SUS) by transfer primary obligations to healthcare operators. The beneficiaries of health insurance plans through regulatory provisions, went on to become privately funded initiative. It happens that the replacement of the State to private without considering the peculiarities of the sector has resulted in the depletion of the financial ability of health insurance companies, indicating that the mode of regulation designed for the segment may not be consistent with the optimization of this scarce resource
Dispelling the Myths Behind First-author Citation Counts
We 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
