Livro «Implicações do otimismo, esperança e funcionalidade na qualidade de vida em indivíduos com esclerose múltipla», da autoria de Luísa Maria Reis Pedro
No full textA Professora Doutora Luísa Maria Reis Pedro em boa hora decidiu divulgar o trabalho de investigação que sustentou a sua dissertação de doutoramento: resultou, assim, o livro “Implicações do otimismo, esperança e funcionalidade na qualidade de vida em indivíduos com esclerose múltipla”. É um livro importante porque divulga uma doença que, não sendo das mais conhecidas, é uma das doenças que tem beneficiado das evoluções tecnológicas mais recentes, principalmente no diagnóstico
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
A Perspective on the Revival of Structural (In) Stability With Novel Opportunities for Function: From Buckliphobia to Buckliphilia
Full text linkBuckling of slender structures is traditionally regarded as a first route toward failure. Here, we provide an alternative perspective on a burgeoning movement where mechanical instabilities are exploited to devise new classes of functional mechanisms that make use of the geometrically nonlinear behavior of their postbuckling regimes. Selected examples are highlighted across length-scales to illustrate some of the exciting opportunities that lie ahead.National Science Foundation (U.S.) (CMMI-1129894)National Science Foundation (U.S.) (Faculty Early Career Development (CAREER) Program Award CMMI-1351449
Localization through Surface Folding in Solid Foams under Compression
No full textWe report a combined experimental and theoretical study of the compression of a solid foam coated with a thin elastic film. Past a critical compression threshold, a pattern of localized folds emerges with a characteristic size that is imposed by an instability of the thin surface film. We perform optical surface measurements of the statistical properties of these localization zones and find that they are characterized by robust exponential tails in the strain distributions. Following a hybrid continuum and statistical approach, we develop a theory that accurately describes the nucleation and length scale of these structures and predicts the characteristic strains associated with the localized regions.European Union MechPlant NESTAdventure progra
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
E-Portefólios no 1º Ciclo do Ensino Básico - Estratégia de promoção e certificação de competências
Full text link"Durante os últimos anos tem-se verificado um interesse crescente pela utilização de e portefólios em contexto educativo, em resultado das potencialidades que lhes são atribuídas na promoção e avaliação de competências.Esta investigação interpretativa, de tipo qualitativo, pretendeu estudar as potencialidades e limitações da utilização de portefólios electrónicos em escolas do 1º Ciclo do Ensino Básico e propor modelos de e-portefólios adequados à realidade deste nível de ensino. Procedeu-se: 1) à análise global dos e-portefólios produzidos no Distrito de Santarém no âmbito do Projecto CBTIC@EB1 - Projecto de Competências Básicas em TIC - durante o ano lectivo de 2005-2006; e 2) à construção de três estudos de caso, onde se analisa e discute a forma como professores, alunos e monitores se envolveram na dinamização de e-portefólios. Com base nos resultados obtidos, procedeu se à concepção de dois modelos de e-portefólio que procuram adequar-se à realidade específica das escolas do 1º Ciclo portuguesas, potenciando as vantagens educativas desta metodologia e ultrapassando as dificuldades detectadas no estudo empírico prévio.--Palavras-chave: Certificação de competências, e-portefólios, portabilidade, reflexão.--MARQUES, Cidália & REIS, Pedro (2009).

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
