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

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
Sistema de integração do conecimento organizacional pelo design thinker
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-graduação em Engenharia e Gestão do Conhecimento, Florianópolis, 2011Após a aplicação do Modelo Organizacional de Autogestão, desenvolvido para organizar administrativa e produtivamente grupos que desejassem promover a autogestão (FORNASIER, 2005), verificou-se a dificuldade para incorporá-la, ocasionada principalmente pela forma de constituição do grupo, pela falta de aprendizagem dos integrantes para formar uma organização e para assumir a autogestão o que resultou na fragmentação do grupo quando do afastamento da academia. Diante disto, o objetivo desta tese é desenvolver um Sistema de Integração do Conhecimento para ser utilizado por organizações colaborativas que desejam promover o perfil de agente de aprendizagem nos seus gestores. O sistema será realizado a partir da pesquisa do Conhecimento Organizacional preestabelecido, das organizações colaborativas referenciais da vitivinicultura, ao ser inserida a inovação, a qual o gestor deve prover a aprendizagem e a integração do conhecimento. Tem-se como premissa da pesquisa analisar quais são: os repositórios de conhecimento dessas organizações; como estes inserem a inovação na organização, da qual origina o Conhecimento Organizacional Distribuído; de que maneira ocorre a integração do conhecimento nos grupos. A pesquisa está fundamentada na metodologia de natureza descritiva e seu delineamento apoia-se em pesquisa bibliográfica, que estuda primeiramente a relação das Teorias de Aprendizagem com a Aprendizagem Organizacional e desta com a Gestão do Conhecimento, de McElroy (2003). Coloca-se, em paralelo a última, o pensamento do designer de Jones (1978), justificado pelo estudo do sistema de conhecimento pessoal do design thinker de Martin (2009). Utiliza-se a metodologia etnográfica pela abordagem mista de Milies e Huberman (1994), para a realização da pesquisa de campo, que tem na sua essência a fusão da etnografia e da teoria enraizada, reforçando o perfil analítico e sintético do designer, como instrumento para aplicação dos procedimentos gerais da pesquisa de campo. Tem-se como resultado da tese o desenvolvimento de um Sistema de Integração do Conhecimento, baseado na observação dos conhecimentos, habilidades e atitudes utilizados pelos gestores das organizações colaborativas referenciais, ao inserirem a inovação e integrá-la, relacionando-os com os conhecimentos, habilidades e atitudes dos gestores de design apresentadas por Brown (2009); Mozota (2003); Martin (2009) e Cross (2007)
Bicontinuous cubic liquid crystalline phase nanoparticles stabilized by softwood hemicellulose
No full textThe colloidal stability of lipid based cubosomes, aqueous dispersion of inverse bicontinuous cubic phase, can be significantly increased by a stabilizer. The most commonly used stabilizers are non-ionic tri-block copolymers, poloxamers, which adsorb at the lipid-water interface and hence sterically stabilize the dispersion. One of the challenges with these synthetic polymers is the effect on the internal structure of the cubosomes and the potential toxicity when these nanoparticles are applied as nanomedicine platforms. The natural polysaccharide, softwood hemicellulose, has been proved to be an excellent stabilizer for oil-in-water emulsions, partially due to the presence of hydrophobic lignin in the extract which to some extent is associated to hemicellulose. Herein, we reported for the first time cubosomes stabilized by two types of softwood hemicelluloses, where one is extracted through thermomechanical pulping (TMP, low lignin content) and the other obtained from sodium-based sulfite liquor (SSL, high lignin content). The effect of the two hemicellulose samples on the colloidal stability and structure of monoolein-based cubosomes have been investigated via DLS, SAXS, AFM and cryo-TEM. The data obtained suggest that both types of the hemicelluloses stabilize monoolein (GMO) based cubosomes in water without significantly affecting their size, morphology and inner structure. SSL-extracted hemicellulose yields the most stable cubosomes, likely due to the higher content of lignin in comparison to TMP-stabilized ones. In addition, the stability of these particles was tested under physiological conditions relevant to possible application as drug carriers
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
Wavelet Decomposition Method for L-2/TV-Image Deblurring
No full textIn this paper, we show additional properties of the limit of a sequence produced by the subspace correction algorithm proposed by Fornasier and Schonlieb [SIAM J. Numer. Anal., 47 (2009), pp. 3397-3428 for L 2/TV-minimization problems. An important but missing property of such a limiting sequence in that paper is the convergence to a minimizer of the original minimization problem, which was obtained in [M. Fornasier, A. Langer, and C.-B. Schonlieb, Numer. Math., 116 (2010), pp. 645-685 with an additional condition of overlapping subdomains. We can now determine when the limit is indeed a minimizer of the original problem. Inspired by the work of Vonesch and Unser [IEEE Trans. Image Process., 18 (2009), pp. 509-523], we adapt and specify this algorithm to the case of an orthogonal wavelet space decomposition for deblurring problems and provide an equivalence condition to the convergence of such a limiting sequence to a minimizer. We also provide a counterexample of a limiting sequence by the algorithm that does not converge to a minimizer, which shows the necessity of our analysis of the minimizing algorithm.open4
