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

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

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
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Implementação do sistema de investigação, desenvolvimento e inovação na Porcel, S.A.
No full textMestrado em Engenharia e Gestão IndustrialO presente trabalho surge na sequência da implementação do Sistema de
Investigação, Desenvolvimento e Inovação (IDI), para a Porcel, S.A., uma
empresa do sector da porcelana de uso doméstico e decorativo, sendo que a
pesquisa bibliográfica permitiu identificar os conceitos importantes para a
análise e Desenvolvimento de Novos Produtos (DNP).
No caso da empresa em estudo, apenas eram realizadas actividades de
Concepção e Desenvolvimento (C&D), sem a preocupação de promover a
inovação. Nesse sentido, a elaboração e acompanhamento do sistema de
gestão de IDI, constitui uma importante ferramenta para uma melhor
orientação das acções de DNP de forma mais eficiente e segura.
Neste relatório é descrito o comportamento dos mercados para o sector em
causa, assim como as etapas do processo produtivo, para uma melhor
compreensão dos aspectos referidos no caso de estudo. São evidenciadas as
diferentes actividades de C&D na empresa e, sobretudo, o novo processo de
IDI e suas ferramentas, dando origem à primeira decoração com a filosofia
inovadora na empresa, a decoração “Tuareg”. Ainda em relação a esta, são
referidas as diferentes e inovadoras matérias-primas e método de aplicação
usado.
Relativamente ao DNP, a empresa considera ter sido dado “um passo”
fundamental para a celeridade do processo e para a implementação da
inovação.The present work is the outcome of the implementation of the System of
Research, Development and Innovation (IDI) for Porcel, S.A., a company of the
sector of the porcelain of domestic and decorative use. The bibliographical
research allowed the identification of the important concepts for the analysis
and Development of New Products (NPD).
Formerly, Conception and Development (C&D) activities were carried out, in
the case of the company under analysis, without any deliberative concern to
promote the innovation. In this direction, the elaboration and accomplishment of
a IDI management system constitutes an important tool for a better orientation
of NPD activities in a more efficient and reliable way.
This project describes the behaviour of the industry products markets as well
as the production process stages, for a better understanding of the aspects
related in the study case. The different C&D activities are evidenced in the
company and, over all, the new process of IDI and its tools, giving origin to the
first decoration with the innovative philosophy in the company, the decoration
“Tuareg”. In the final part of the project is described the different and innovative
raw materials and method used for their application.
Relatively to the NPD, the company considers to have been given a
fundamental step for the celerity of the process and for the implementation of
new product innovations
