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
L'évolution de la nuptialité des adolescentes au Cameroun et ses déterminants
No full textKuate-Defo Barthélémy. -Adolescent nuptiality in Cameroon : change and its determinants Three successive and nationally representative surveys and an event history analysis were used to test the hypothesis that marriage before age 20 is becoming less frequent in Cameroon. Assessment of the data shows that the information supplied by women in the 20- 34 age range, and in particular between 20-24, is the most reliable for studying the changes in marriage behaviour on the basis of multiround retrospective surveys. Early marriage is declining in nearly all regions of the country, and at the national level is reflected in a strong trend towards later marriage. The decline in early marriage is most pronounced among women of the younger generations, the better educated, those living in the cities of Yaounde and Douala, among Muslims and followers of the traditional religions. The fall in age at menarche is concomitant with a fall in age at first marriage, and women who experience puberty early marry earlier than those who experience puberty later. The main findings from this study and their implications are discussed in the light of research conducted elsewhere, notably in other developing countries.Kuate-Defo Barthélémy. - L'évolution de la nuptialité des adolescentes au Cameroun et ses déterminants À partir de trois enquêtes successives représentatives au niveau national et au moyen d'une analyse des biographies, on teste l'hypothèse que l'entrée en vie conjugale avant 20 ans est de moins en moins fréquente au Cameroun. L'évaluation des données montre que les informations fournies par les femmes de 20-34 ans, et surtout de 20-24 ans, sont les plus fiables pour cerner les changements matrimoniaux à partir d'enquêtes rétrospectives répétées. La nuptialité précoce diminue dans la quasi-totalité des régions du pays, induisant au plan national une forte tendance au report des unions. Le déclin de la nuptialité précoce est le plus ma- qué parmi les femmes des jeunes générations, les plus scolarisées, les résidentes des grandes villes de Yaoundé/Douala, les musulmanes et les adeptes des religions traditionnelles. Le déclin de l'âge aux premières règles est concomitant d'un recul de l'âge à la première union, et les femmes pubères précocement entrent en union plus tôt que celles dont la puberté est tardive. Les principaux résultats de cette étude et leur portée sont discutés à la lumière des travaux de recherche réalisés ailleurs, notamment dans d'autres pays en développement.Kuate-Defo Barthélémy. - La evolución de la nupcialidad adolescente en Camerun y sus déterminantes En base a très encuestas sucesivas, representativas a nivel nacionál, y a partir de un análisis biográfico, evaluamos la hipótesis según la cual el inicio de la vida conyugal antes de los 20 aňos es cada vez menos frecuente en Camerún. La evaluación de datos muestra que las informaciones proporcionadas por mujeres de entre 20 y 34 aflos de edad, y especialmente entre 20 y 24, son las más fiables para analizar los cambios matrimoniales a partir de encuestas retrospectivas repetidas. La nupcialidad precoz ha disminuido en casi todas las regiones del pais, induciendo un retraso de las uniones. La disminución de la nupcialidad precoz es más fuerte entre las mujeres de generaciones jóvenes, las de mayor nivel educativo, las résidentes en las grandes ciudades de Yaoundé/Duala, las musulmanas y las adeptas a las religiones tra- dicionales. Por otro lado, la edad de la primera régla ha disminuido de forma simultanea a la disminución de la edad a la primera union. Pero las mujeres que entran en la adolescencia a edades más précoces también entran en uniones más temprano que las mujeres cuya pubertad es más tardía. El artículo discute los resultados principales de este estudio y su alcance a la luz de estudios realizados en otros parses en desarrollo.Kuate-Defo B.

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
Defo-Net: Learning Body Deformation using Generative Adversarial Networks
No full textModelling the physical properties of everyday objects is a fundamental prerequisite for autonomous robots. We present a novel generative adversarial network (DEFO-NET), able to predict body deformations under external forces from a single RGB-D image. The network is based on an invertible conditional Generative Adversarial Network (IcGAN) and is trained on a collection of different objects of interest generated by a physical finite element model simulator. Defo-netinherits the generalisation properties of GANs. This means that the network is able to reconstruct the whole 3-D appearance of the object given a single depth view of the object and to generalise to unseen object configurations. Contrary to traditional finite element methods, our approach is fast enough to be used in real-time applications. We apply the network to the problem of safe and fast navigation of mobile robots carrying payloads over different obstacles and floor materials. Experimental results in real scenarios show how a robot equipped with an RGB-D camera can use the network to predict terrain deformations under different payload configurations and use this to avoid unsafe areas
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
