Proveedores Online
No full textProveedores Online es un sistema que mejora el proceso de pago a proveedores, desde la recepción de una factura hasta el pago de la misma y la administración de consultas y reclamos. Permite centralizar la información de pagos a proveedores dentro de una empresa y crear un solo canal más eficiente de consultas y reclamos respecto a la facturación. Al ser multiplataforma puede ser consultado por múltiples empresas y múltiples proveedores en cualquier dispositivo y en cualquier momento, agilizando los procesos.Fil: Gonzalez Soler, Juan Cruz.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Variations on the Author
Get PDF“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
Get PDFWe 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
Microfluidic control of oxygen for long-term maintenance of tissues on chip
Get PDFCurrent in vitro models used for physiological studies and drug development present several drawbacks. They are not able to accurately replicate the in vivo architectures, morphologies, cell diversity and the communications and interactions between the cells and their microenvironments. In this context, micro physiological systems (MPS) technology arises as a new opportunity to overcome these issues. This technology includes organ-on-chip, which in just a few years, they have become a key tool for the modelling of organ functions and the study of disease states and is already presenting promising results and breakthroughs. Another branch of MPS is tissue-on-chip, which instead of culturing cells in a predetermined artificial architecture, the samples are biopsies extracted directly from the body. The culture of tissue explants presents many advantages, for example, they preserve the original three-dimensional architecture, cell types and extracellular matrix of the tissues in vivo. However, this field as not been yet widely explored and still presents many challenges. The aim of this project is the development of new technologies for extending the viability of tissue biopsies in vitro. The main challenges of the long-term culture of tissue explants are the adequate supply of oxygen and nutrients, and the removal of waste. This project seeks to study the oxygen concentration affects the survival ex vivo of tissues to optimise the culture conditions and increase our understanding of the behaviour of the samples outside of the body. A microfluidic platform able to control oxygen concentrations inside culture chambers, with an integrated electronic oxygen sensor to monitor in situ and in real time the gaseous microenvironment has been developed. The system is optimised for the culture of cells in the microfluidic chambers under continuous perfusion and with the ability to subject the samples to specific oxygen tensions. The response of the tissues to hypoxic challenges is measured by looking at the changes in the expression of hypoxia-induced genes
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
