Humility: Virgin or Virtue?
2021
Este trabajo considera la iconografía mariana en la que se representa a la Virgen sentada en el suelo, conocida como la Virgen de la Humildad. La creación de este tipo mariano coincide con la sistematización de las virtudes de Santo Tomás, que dio lugar a una disminución en la importancia de la virtud de la humildad. La combinación de ambas tradiciones culturales ha llevado a una correspondencia entre la virtud de la Humildad y las imágenes de la Virgen de la Humildad. La génesis de este último tipo se basa en las fuentes textuales y parte de la representación visual de la Humildad, que fue sustituida durante los siglos XIV y XV.

Mediated sacralization and the construction of postmodern communio sanctorum: The case of the Swedish foreign minister anna lindh
2005
In the media age, the linkage between mediated communities and images is established by the sacralization of images. Based on the theoretical insights of Michel Maffesoli and on an influential tradition in French sociology, which includes Emile Durkheim, Georges Bataille, and Rene Girard, this article attempts to apply the theory of sacred images to the empirical analysis of images in the media. The analysis of the Swedish and Finnish newspapers' visual coverage of the assassination of Swedish Foreign Minister Anna Lindh suggests that the process of sacralization is actually performed as a communicative behavior involving the media and the crowd as the main actors and a number of symbols wh…
A few remarks on the Inedita Pseudo-Chrysostomic Homily De transfiguratione et eleemosyna (CPG 5009; BHGn 1996t)
2021
The article presents the preliminary results of the author’s study of the unedited homily De transfiguratione et eleemosyna (CPG 5009; BHGn 1996t), ascribed to John Chrysostom. The question of the manuscript tradition is first discussed. The article shows that Maurice Sachot is right when he indicates only the manuscript Romanus Angelicus gr. 125 (T.1.7) as a manuscript witness of this homily and that the other two witnesses indicated by Pinakes are erroneous. Then, the descriptions of the folios that preserve the homily are analysed in the light of a new examination of them. This re-examination shows that hitherto several sources that inspired the compiler have gone unnoticed. This is foll…
Congenital Hepatic Fibrosis
2005
The disease presentation of autosomal recessive polycystic kidney disease (OMIM #263200, ARPKD) is highly variable and includes polycystic kidneys, pulmonary hypoplasia, and congenital hepatic fibrosis. The authors report an unusual case of ARPKD presenting with hepatosplenomegaly and cytopenia mimicking acute leukemia.
Antigen-presenting function and B7 expression of murine sinusoidal endothelial cells and Kupffer cells.
1996
Abstract BACKGROUND & AIMS: Inflammatory liver disease as well as rejection of liver allografts are thought to be mediated by resident antigen- presenting cells in the liver. At the same time, in vivo antigen presentation in the liver appears to be a more tolerogenic than systemic antigen challenge. The aim of this study was to show and characterize the antigen-presenting capability of sinusoidal endothelial cells and Kupffer cells. METHODS: Purified murine sinusoidal endothelial cells and Kupffer cells were studied for their ability to serve as accessory cells and antigen-presenting cells by proliferation assays. They were also studied for their expression of interleukin 1 and the B7 costi…
IL-10 down-regulates T cell activation by antigen-presenting liver sinusoidal endothelial cells through decreased antigen uptake via the mannose rece…
1998
SUMMARYOur study demonstrates that antigen-presenting liver sinusoidal endothelial cells (LSEC) induce production of interferon-gamma (IFN-γ) from cloned Th1 CD4+ T cells. We show that LSEC used the mannose receptor for antigen uptake, which further strengthened the role of LSEC as antigen-presenting cell (APC) population in the liver. The ability of LSEC to activate cloned CD4+ T cells antigen-specifically was down-regulated by exogenous prostaglandin E2 (PGE2) and by IL-10. We identify two separate mechanisms by which IL-10 down-regulated T cell activation through LSEC. IL-10 decreased the constitutive surface expression of MHC class II as well as of the accessory molecules CD80 and CD86 …
Coarse-Grained Barrier Trees of Fitness Landscapes
2016
Recent literature suggests that local optima in fitness landscapes are clustered, which offers an explanation of why perturbation-based metaheuristics often fail to find the global optimum: they become trapped in a sub-optimal cluster. We introduce a method to extract and visualize the global organization of these clusters in form of a barrier tree. Barrier trees have been used to visualize the barriers between local optima basins in fitness landscapes. Our method computes a more coarsely grained tree to reveal the barriers between clusters of local optima. The core element is a new variant of the flooding algorithm, applicable to local optima networks, a compressed representation of fitnes…
Iterative approach to the exponential representation of the time–displacement operator
2005
An iterative method due to Voslamber is reconsidered. It provides successive approximations for the logarithm of the time–displacement operator in quantum mechanics. The procedure may be interpreted, a posteriori, as an infinite re-summation of terms in the so-called Magnus expansion. A recursive generator for higher terms is obtained. From two illustrative examples, a detailed comparative study is carried out between the results of the iterative method and those of the Magnus expansion.
Thought and Body. An activity of Logic in primary school
2015
Abstract In the recent decades, the pedagogical debate has been formerly traversed by the emergence an then by the assertion of a matured awareness on the importance of the psychomotor skills in the educational-didactic path. The interpretive bio-psycho-social matrix has today become one of the pivotal points on which the educational-didactic activity rests and develops for the training of child's personality in its full motor, mental, perceptual, emotional, sensory development. Pedagogues, educators, and training professionals are increasingly confident that, since the birth, children are sensitive to the stimuli and to the environmental intervention, therefore it's essential to know their…
Mental Images and School Learning: A Longitudinal Study on Children
2019
Recent literature have underlined the connections between children’s reading skills and capacity to create and use mental representations or mental images; furthermore data highlighted the involvement of visuospatial abilities both during math learning and during subsequent developmental phases in performing math tasks. The present research adopted a longitudinal design to assess whether the processes of mental imagery in preschoolers (ages 4–5 years) are predictive of mathematics skills, writing and reading, in the early years of primary school (ages 6–7 years). The research lasted for two school years; in the first phase, the general group of participants consisted of 100 children, and al…
