Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Relações dos alunos com o aprender no ensino de biologia por atividades investigativas
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina. Programa de Pós-graduação em Educação Científica e TecnológicaEsta pesquisa tem como objetivo investigar as relações de alunos com o aprender Biologia por atividades investigativas no nível médio de ensino. Como base teórica, a pesquisa se inspira nos estudos da Relação com o Saber, de Bernard Charlot. Privilegio a relação epistêmica com o aprender dos estudos de Charlot que discute que o aprender pode assumir diferentes significados para os alunos. Nas análises das relações dos alunos, identifico e discuto os sentidos que atribuem ao aprender no processo educativo. Os dados foram coletados a partir de observações de aulas de uma professora que realiza o Ensino de Biologia por atividades investigativas e, principalmente, de entrevistas semi-estruturadas com os alunos e a professora. Para analisar os dados, privilegio três formas de relação epistêmica com o aprender dos estudos de Charlot: (a) objetivação-denominação, em que aprender constitui na apropriação e enunciação de conteúdos intelectuais; (b) imbricação do eu, na qual o aprender é o domínio de uma atividade que o aluno aprendiz desempenha; (c) distanciação-regulação, em que o aprender se remete ao domínio de relações afetivas, como emoções, sentimentos e percepções que o aluno estabelece a fim de construir uma imagem reflexiva de si e, paralelamente, uma leitura do contexto em que está inserido. Nesta análise, levo em consideração questões que influenciam na constituição das relações epistêmicas dos alunos com o aprender, como as interpretações singulares dos alunos sobre o aprender e também o contexto educacional que estavam imersos: proposta pedagógica da escola que os alunos estudam, perspectiva do Ensino de Biologia por atividade investigativas que a professora ministrava e situação sócio-econômica dos alunos. Os resultados apontam que os alunos estabelecem diferentes relações epistêmicas com o aprender Biologia por atividades investigativas. Os sentidos atribuídos ao aprender se estabelecem na enunciação dos conteúdos biológicos, no domínio de atividades investigativas das Ciências Biológicas e na relação reflexiva sobre si próprios e a sociedade. Aponto que as relações com o aprender estabelecidas pelos alunos privilegiam concepções da atividade investigativa como execução de atividades experimentais de forma empírica, objetiva e afastada das relações e implicações com a Sociedade. No entanto, discuto que os sentidos atribuídos ao aprender devem superar a concepção neutra da Ciência (do conhecimento com existência em si próprio), promovendo reflexões sobre relações entre Ciência e Sociedade que são fundamentais para as relações dos alunos com o aprender Biologia por atividades investigativas na Educação Básica. This research aims to investigate the relation of students to learn Biology by investigative activities in High School level. The theoretical base for this research is the studies of the Relation to Knowledge of Bernard Charlot, privileging the epistemic relation with learning which discuss that learn can assume different meanings for students. Thus, through the analyses of the students' relations, I identify and discuss which meanings with learning students attribute in the educative process. The data were collected from observations of classrooms of a teacher who performs on the teaching of Biology by investigative activities and, mainly, by semi-structured interviews with the teacher and students. To analyse data, I raise three forms od epistemic relation with learning of Charlot's studies: (a) "objectivation-denomination" in which learning constitutes the appropriation and enunciation of intellectual contents; (b) "overlap of me" in which learning is referred to an activity, in this research, the investigative activity; (c) "distance-regulation" in which learning is referred to an affectionate (emotional) relations, such as emotions, feelings and perceptions that student establishes in order to build a reflective image of themselves and, in parallel, an interpretation of the context in which it is inserted. I consider into the analyses issues that influence the constitution of students' epistemic relations with learning, as the individual interpretation about learning and also the educational context that they were immersed: pedagogical proposal of the school, the perspective of Biology teaching by investigative activity and social-economic situation of the students. The results present that students establish different epistemic relations to learn Biology by investigative activities. The meanings attributed to learn establish in enunciation of the biological contents, in the field of investigative activities of the Biological Sciences and in the reflective relation of themselves and Society. I point out that the relations with learning established by the students focus on conceptions of investigative activity like an execution of experimental activities in empirical, objective and remote from the relations and implications with Society. However, I discuss that the meanings attributed to learn by students must overcome the neutral conception of Science (the knowledge of the existence in itself), promoting reflections on relations between Science and Society. These reflections are fundamental to the relation of students to learn Biology by investigative activities in Basic Education
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
