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

Selecting new Brachiaria humidicola hybrids for western Brazilian Amazon.
No full textBrachiaria humidicola is a perennial and stoloniferous forage grass, with excellent adaptation to infertile soils and waterlogging. Producers in northern Brazil have become interested in this species, especially after the degradation of large areas of lowly permeable soils sown with B. brizantha cv. Marandu, which is highly intoler-ant of soil waterlogging (Andrade and Valentim 2006). However, since only 3 cultivars of B. humidicola are registered in Brazil (Mapa 2013), there is a need to de-velop new cultivars adapted to the range of environ-mental conditions experienced. Recently, Embrapa Beef Cattle obtained intraspecific hybrids of B. humidicola that need to be evaluated agronomically, aiming at sub-sequent grazing trials and future releases. The objective of this study was to evaluate and select apomictic and sexual hybrids of B. humidicola under the environmental conditions of the state of Acre, in western Brazilian Amazon.Publicado também nos Anais do 22º INTERNATIONAL GRASSLAND CONGRESS, Sidney, 2013
Modelagem de conhecimento estratégico nos processos de negócio: proposta de um modelo suportado pela metodologia CommonKADS
No full textDissertação (mestrado) - Univesidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Engenharia e Gestão do ConhecimentoOs processos de negócio abrigam conhecimento em diversos formatos e níveis de importância. Esse conhecimento necessita ser mapeado de acordo com as diretrizes estratégicas da organização. Desta forma, este estudo pretende resolver, através da Engenharia do Conhecimento, o seguinte problema: Como modelar o conhecimento estratégico presente nos processos de negócio? O objetivo geral é propor um modelo organizacional que permita priorizar o conhecimento estratégico presente nos processos de negócio, representando-o de forma a obter diretrizes que orientem os software a suportar a gestão do conhecimento, ampliando a performance organizacional. Os objetivos específicos são: identificar e definir critérios para determinar o que é conhecimento estratégico nos processos de negócio; alinhar a visão estratégica à formalização do conhecimento estratégico presente nos processos de negócio; estabelecer indicadores para a avaliação da aderência da modelagem do conhecimento estratégico com os sistemas de apoio às práticas de GC; estabelecer a aplicação da metodologia CommonKADS para verificação do modelo proposto. Este estudo classifica-se como uma pesquisa exploratória, com a aplicação do modelo criado através de estudos de caso nas empresas Docol Metais Sanitários e Claris Portas e Janelas. Como resultados alcançados têm-se a formulação de um modelo com orientação estratégica, estruturado para modelagem de conhecimento nos processos de negócio; a aplicação do modelo através de estudo de caso e a contribuição para o desenvolvimento de propostas de modelos que auxiliem as organizações a sustentar suas estratégias de Gestão do Conhecimento através de técnicas de Engenharia do Conhecimento
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
Effect of environmental factors and management practices on nitrogen fixation of rhizoma peanut and transfer of nitrogen from the legume to an associated grass.
No full textThis research was conducted to test the hypotheses that a) environmental factors (soil temperature and soil moisture) and mangement practices (defoliation and nitrogen fertilization) affect growth and nitrogen fixation of Florigraze rhizoma peanut (Arachis glabrata Benth.) and that b) during the establishment of rhizoma peanut the legume transfers symbiotically fixed nitrogen to an associated grass.Dissertation (Doctor of Philosophy) - Graduate School, Universidade of Florida, Gainesville.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
