Institutional open access repositories: adapting to new web metrics

Institutional open access repositories are essential in today’s scholarly communication system. It´s observed significant growth of its use by public institutions of higher education in Brazil in the last fifteen years. The use of the web environment for production, storage, dissemination and access to scientific and technological information grows, impacting the entire structure of scientific communication. This new format needs new indicators for the metric studies of scientific and technological information, as webometric and altmetrics indicators. Through exploratory and descriptive research, it shows how these institutions are adapting their repositories to the new scenario. It was identified that 70% of the repositories provide statistical data on access and download of its items, 22% offer altmetric data, 83% use “identifiers resolution system” of digital objects. It shows that public higher education institutions are now adapting their repositories to the new scenario of metric information studies, and altmetrics presents incipient results

Personal data usage and privacy considerations in the COVID-19 global pandemic

Data has become increasingly important and valuable for both scientists and health authorities searching for answers to the COVID-19 crisis. Due to difficulties in diagnosing this infection in populations around the world, initiatives supported by digital technologies are being developed by governments and private companies to enable the tracking of the public’s symptoms, contacts and movements. Considering the current scenario, initiatives designed to support infection surveillance and monitoring are essential and necessary. Nonetheless, ethical, legal and technical questions abound regarding the amount and types of personal data being collected, processed, shared and used in the name of public health, as well as the concomitant or posterior use of this data. These challenges demonstrate the need for new models of responsible and transparent data and technology governance in efforts to control SARS-COV2, as well as in future public health emergencies

Preservação da privacidade no enfrentamento da COVID-19: dados pessoais e a pandemia global

Data is becoming ever more critical and valuable for both scientists and health authorities searching for answers to the COVID-19 crisis. Due to difficulties in diagnosing this infection in populations around the world, initiatives supported by digital technologies have been developed by governments or private companies which enable the tracking of the public’s symptoms, contacts and movements. Considering the current scenario, these initiatives, designed to support the surveillance and monitoring of contagion, are essential and necessary.  Nonetheless, ethical, legal and technical questions remain unanswered regarding the amount and types of personal data being collected, processed, shared and used in the name of public health, as well as the concomitant or later use of this data. These challenges demonstrate the need for new models of responsible and transparent data and technology governance in efforts to control Sars-Cov2 as well as future public health emergencies.Dados ganham cada vez mais importância e valor na busca de respostas para enfrentar a COVID-19 tanto para ciência quanto para as autoridades sanitárias. Em virtude da dificuldade de realizar diagnóstico da infecção na população em geral, iniciativas apoiadas em tecnologias digitais vem sendo desenvolvidas por governos ou empresas privadas para possibilitar rastreamentos de sintomas, contatos e deslocamentos para apoiar estratégias de acompanhamento e avaliação na vigilância de contágios. A despeito da importância e necessidade dessas iniciativas, questionamentos acerca da quantidade e tipos de dados pessoais coletados, processados, compartilhados e utilizados em nome da saúde pública, bem como os concomitantes ou posteriores usos desses dados, suscitam questionamentos éticos, legais e técnicos. Desafios que apontam para a necessidade de novos modelos de governança de dados e de tecnologias, responsáveis e transparentes, para controlar o Sars-Cov2 e as futuras emergências de saúde pública

Moderately hypofractionated post-operative radiation therapy for breast cancer: Preferences amongst radiation oncologists from countries in Latin America and the Caribbean

Background: The safety and effectiveness of moderately hypofractionated post-operative radiation therapy for breast cancer were demonstrated by several trials. This study aimed to evaluate the current patterns of practice and prescription preference about moderately hypofractionated post-operative radiation therapy to assess possible aspects that affect the decision-making process regarding the use of fractionation in breast cancer patients in Latin America and the Caribbean (LAC). We also aimed to identify factors that can restrain the utilization of moderately hypofractionated post-operative radiation therapy for breast cancer. Materials an methods: Radiation oncologists from LAC were invited to contribute to this study. A 38-question survey was used to evaluate their opinions. Results: A total of 173 radiation oncologists from 13 countries answered the questionnaire. The majority of respondents (84.9%) preferred moderately hypofractionated post-operative radiation therapy as their first choice in cases of whole breast irradiation. Whole breast plus regional nodal irradiation, post-mastectomy (chest wall and regional nodal irradiation) without reconstruction, and post-mastectomy (chest wall and regional node irradiation) with reconstruction hypofractionated post-operative radiation therapy was preferred by 72.2% 71.1%, and 53.7% of respondents, respectively. Breast cancer stage, and flap-based breast reconstruction were the factors associated with absolute contraindications for the use of hypofractionated schedules. Conclusion: Even though moderately hypofractionated post-operative radiation therapy for breast cancer is considered a new standard to the vast majority of the patients, its unrestricted application in clinical practice across LAC still faces reluctance

Rio de Janeiro, RJ, BrasilCampo das metrias da informação com nove anos de existência, a altmetria existe no Brasil há seis anos. Se o campo for considerado de forma mais ampla, tomando-se, como exemplo, estudos cientométricos a partir de dados cibermétricos ou webométricos, é possível identificar trabalhos mais antigos. Entretanto, o processo de delimitação do referido campo se deu em 2010, quando Jason Priem cunhou o termo “altmetrics” via Twitter, tendo o mencionado vocábulo chegado ao Brasil como “altmetria” em 2013. No estudo bibliométrico exploratório aqui apresentado é utilizada a base de currículos Lattes para identificar artigos e comunicações em congressos de pesquisadores, com ou sem doutorado, que atuam no campo da altmetria no Brasil. Ademais, serão também identificadas as suas grandes áreas, além de áreas de atuação, distribuição geográfica e a evolução de fontes de dados e as temáticas ao longo dos anos. Para tanto, foi efetuada a identificação dos currículos por intermédio da busca avançada na Plataforma Lattes, utilizando-se os termos “altmetria”, “altmétrico”, “altmétrica”, “altmetric” ou “altmetrics”. Os 94 currículos encontrados, sendo 37 de doutores e 57 de não doutores, tiveram seus conteúdos filtrados pelos termos de busca utilizados. Foram identificados 26 artigos em periódicos e 36 comunicações em congressos. Dos 94 pesquisadores, 53 deles produziram apenas em altmetria e 41 produziram valendo-se da intercessão com Facebook, Twitter ou Mendeley. O campo é dominado por pesquisadores da grande área de Ciências Sociais Aplicadas, destacando-se a Ciência da Informação e, em menor grau, a área da Comunicação. As abordagens vêm evoluindo, percorrendo um caminho que vai desde aquelas mais teóricas até as práticas, avaliativas, críticas e as contextualizações institucionais e regionais.Field of the information metrics studies with nine years of existence, altmetrics has in Brazil a history three years more recent. If, on the other hand, we consider the field more broadly, such as scientometric studies based on cybermetric or web-based data, we could identify older works. However, delimitation of the field occurred in 2010, when Jason Priem coined the term “altmetrics” via Twitter having arrived in Brazil as “altmetria” in 2013. In the exploratory bibliometric study here presented, we used the Lattes curriculum to identify articles and communications in congresses of researchers, with or without a doctorate degree, who work in the field of altmetrics in Brazil, their large areas and areas of expertise, geographical distribution and the evolution of data and thematic sources over the years. To this end, the identification of curricula was made through the advanced search in the Lattes Platform by the terms “altmetria”, “altmétrico”, “altmétrica”, “altmetric” or “altmetrics”. The 94 curricula found, 37 of which were doctors and 57 of non-doctors, had their contents filtered by the search terms used. Twenty-six articles were identified in periodicals and 36 communications in events. From the 94 researchers it is verified that 53 of them produced only in altmetrics and 41 with intercession with Facebook, Twitter or Mendeley. The field is dominated by researchers from the large area of Applied Social Sciences with emphasis on Information Science and to a lesser extent for Communication. Research focus have been evolving from more theoretical approaches towards practical, evaluative, critical and institutional and regional contexts

Altmetria: métricas de produção científica para além das citações │ Altmetrics: scientific production metrics beyond citations

Resumo Métricas baseadas em citações têm sido historicamente utilizadas para avaliação da produção científica. Entretanto, diante da revolução da Web 2.0 surge uma Cientometria 2.0, que busca celeridade na percepção do impacto das publicações científicas, bem como de campos emergentes e estratégicos. Neste contexto se inserem os estudos com métricas alternativas (altmétricas) que tem o potencial de aprimorar o entendimento das dinâmicas de citação, levando em consideração o contexto e o papel das diferentes publicações na academia. Neste artigo apresentamos uma discussão sobre o campo da “altmetria” propondo sua definição como uso de dados webométricos e cibermétricos em estudos cientométricos. Palavras-chave Altmetria, Cibermetria, Webometria, Cientometria, Bibliometria. Abstract Citations based metrics have historically been used to evaluate scientific production. However, before the revolution of Web 2.0 arises Scientometrics 2.0, which seeks to expedite the perception of the impact of scientific publications, as well as strategic and emerging fields. In this context fall within studies with alternative metrics (altmetrics) that has the potential to enhance the understanding of the citation dynamics, taking into account the context and the scholarly role of different publications. This article presents a discussion on the field of “altmetrics” proposing its definition as webometrics and cybermetrics data usage in scientometric studies.
