Ligand depletion negatively controls the mitogenic activity of epidermal growth factor

32682.pdf (Publisher’s version ) (Closed access)EGF activates the ErbB1 receptor, but there appears only a limited correlation between its receptor binding affinity and mitogenic activity. This is indicated by our present observation that in cells with high ErbB1 expression, including SUM102 breast tumor cells, low affinity EGF/Notch chimeras have similarly high mitogenic activity as EGF, in spite of the fact that EGF is superior in inducing receptor tyrosine phosphorylation and p42/p44 MAP-kinase activity. However, as a result of receptor-mediated internalisation high-affinity ligands such as EGF are depleted much more rapidly from the extracellular medium than low-affinity EGF/Notch chimeras. As a consequence, the mitogenic activity of EGF on ErbB1 overexpressing cells is limited by substantial degradation of internalised ligand in the period before cells enter S-phase, a phenomenon that is not observed for low affinity mutant ligands. The mitogenic activity of EGF on ErbB1 overexpressing cells does therefore not only depend on the applied concentration but also on the total amount of ligand added, and is strongly underestimated when tested in a limited assay volume. No such dependence on the incubation volume was observed for EGF activity on cells with low ErbB1 expression levels and on cells for which EGF is growth inhibitory

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
Gestión curricular de la enseñanza de la resolución de problemas matemáticos en docentes del nivel Primaria de la Institución Educativa N° 32682 de Incacocha 2018
Get PDFEl presente trabajo académico denominado Gestión curricular de la enseñanza de la resolución de problemas matemáticos en docentes del nivel primaria de la Institución Educativa N° 32682 de Incacocha 2018. Cuyo objetivo es Mejorar la gestión curricular de la enseñanza de la resolución de problemas matemáticos en docentes del Nivel Primaria de la Institución Educativa N° 32682, como participantes son tres docentes del nivel primario, padres de familia y el directivo. El tipo de investigación es aplicada y su enfoque es cualitativo, es decir abierta, flexible y holística. Se aplicó la técnica de la entrevista y como instrumento la guía de la entrevista, con la finalidad de identificar su percepción sobre la limitada Gestión Curricular Limitada gestión curricular de la enseñanza de la resolución de problemas matemáticos en docentes del Nivel Primaria. Las diferentes acciones estratégicas van a permitir mejorar la práctica de la enseñanza a través de la participación activa de los docentes reflexivos y exhaustivos de su propia práctica. Entre las conclusiones se considera que el director como líder pedagógico es responsable de la Gestión Pedagógica, es el encargado de motivar a los docentes para lograr las metas propuestas, de fomentar el desarrollo de competencias con el propósito de revertir los resultados de la ECE y las actas de evaluación como resultados de aprendizaje de los estudiantes.The present academic work called Curricular management of the teaching of the resolution of mathematical problems in teachers of the primary level of the Educational Institution No. 32682 of Incacocha 2018. The objective of which is to improve the curricular management of the teaching of the resolution of mathematical problems in teachers of the Primary Level of the Educational Institution No. 32682, as participants are three teachers of the primary level, parents and the manager.
The type of research is applied and its approach is qualitative, that is, open, flexible and holistic. The interview technique was applied and the interview guide as an instrument, in order to identify their perception of the limited Curricular Management Limited curricular management of the teaching of mathematical problem solving in teachers of the Primary Level. The different strategic actions will allow to improve the teaching practice through the active participation of reflective and exhaustive teachers of their own practice.
Among the conclusions, it is considered that the principal as a pedagogical leader is responsible for Pedagogical Management, is in charge of motivating teachers to achieve the proposed goals, of promoting the development of competencies with the purpose of reversing the results of ECE and the evaluation records as student learning results.Tesis de segunda especialida
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
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
