Full text linkFil: Gonzalez, Pablo. Universidad de San Andrés. Escuela de Negocios; Argentina.Se analizará la implementación de balanzas de fiscalización utilizando el método WIM, de pesaje en movimiento, para el control de cargas en Argentina. Se abordarán estudios en el plano regional y en los principales países en el plano internacional, con el fin de analizar las mejoras que podría proporcionar este método de medición tanto en el control de cargas como así también en el costo operativo de mantenimiento de las rutas y la seguridad vial
"Models and Methaphors from Biology to Bioinformatics Tools", 4th International Workshop on NETwork Tools and Applications in Biology(NETTAB 2004)
No full textNETTAB 2004 intends to bring together bioscientists and computer scientists and to compare their approaches and their ideas for solving computational biology open problems. In particular, we expect the participation of those who are developing novel bioinformatics tools and those who are working towards the vision of biological systems as a model for designing new tools.
The workshop will also aim to inspire future collaboration between the different communities, to strengthen the relationships within the bioinformatics community, to activate a cooperation between bioscientists and computer scientists, to collect the latest ideas, achievements and proposals in computational models and metaphors from biology.
Topics to be covered will include, but not limited to, the following list:
From Biologists – Open problems in:
• Molecular evolution and theoretical biology
• Gene regulation and expression
• Functional genomics
• Comparative genomics
• Protein structure and interaction

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
Ooids forming in situ within microbial mats (Kiritimati atoll, central Pacific)
Full text linkCRUE-CSIC (Acuerdos Transformativos 2021)Ooids (subspherical particles with a laminated cortex growing around a nucleus) are ubiquitous in the geological record since the Archean and have been widely studied for more than two centuries. However, various questions about them remain open, particularly about the role of microbial communities and organic matter in their formation and development. Although ooids typically occur rolling around in agitated waters, here, we describe for the first time aragonite ooids forming statically within microbial mats from hypersaline ponds of Kiritimati (Kiribati, central Pacific). Subspherical particles had been previously observed in these mats and classified as spherulites, but these particles grow around autochthonous micritic nuclei, and many of them have laminated cortices, with alternating radial fibrous laminae and micritic laminae. Thus, they are compatible with the definition of the term ‘ooid’ and are in fact very similar to many modern and fossil examples. Kiritimati ooids are more abundant and developed in some ponds and in some particular layers of the microbial mats, which leads to the discussion and interpretation of their formation processes as product of mat evolution, through a combination of organic and environmental factors. Radial fibrous laminae are formed during periods of increased supersaturation, either by metabolic or environmental processes. Micritic laminae are formed in closer association with the mat exopolymer (EPS) matrix, probably during periods of lower supersaturation and/or stronger EPS degradation. Therefore, this study represents a step forward in the understanding of ooid development as influenced by microbial communities, providing a useful analogue for explaining similar fossil ooids.Depto. de Mineralogía y PetrologíaFac. de Ciencias GeológicasTRUEpu
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
