Res et signa: los fundamentos de la cultura cristiana. Una aproximación a De Doctrina Christiana de San Agustín
No full textLa concepción agustiniana del texto sacro afirma la fecundidad de la razón humana: la inteligencia que se planta ante el misterio, al tiempo que lo reconoce como tal, podrá alcanzar reflexiones cada vez más profundas. La meditación de san Agustín acerca de la expresión creed y multiplicaos recorre, precisamente, el camino que señalamos con anterioridad; la causa por la cual necesitamos de la materialidad fónica del lenguaje echa raíces en la corporeidad de la persona humana. Gráficamente expresa San Agustín que el abismo del mundo impide que veamos los pensamientos, por lo que resulta necesario la obra de las palabras.Fil: Calabrese, Claudio.

Subcutaneous Tissue Expander Placement with Synthetic Titanium-Coated Mesh in Breast Reconstruction: Long-term Results
Get PDFA subcutaneous, prepectoral, muscle-sparing approach has been recently described for implant-based breast reconstruction. This is a preliminary series of 2-stage breast reconstructions by means of tissue expander placed subcutaneously with the support of a titanium-coated polypropylene mesh. A pilot series of cases was started in 2012. Inclusion criteria were informed consent, age less than 80 years, normal body mass index (range, 18.5-24.9), no T4 and metastatic cancers, no comorbidities, and nonsmoking patients. Expander losses, infections, seromas, skin/nipple necrosis, wound dehiscence, and reinterventions were registered in follow-up visits. Furthermore, patients were followed up in second-stage procedures and for at least 1 year from implant positioning to collect any surgical complication, reinterventions, cosmetic outcome, and oncological data. Between June 2012 and March 2014, 25 cases were enrolled in the study. Expander/implant loss rate was 0%. Skin/nipple necrosis rate was 4%. Infections rate was 12% after first-stage and 4% after second-stage procedure. Seromas rate was 0%. Five (20%) fat graft procedures were performed over the expander before second-stage reconstruction, and no reinterventions were required after second stage. Patients mean score was 99 for cosmetic outcome satisfaction, in a 0-100 scale. Subcutaneous 2-stage reconstruction with synthetic mesh proved safe and feasible. Patients satisfaction is very good after 14 months median follow-up form definitive implant placement. Although the present study involved only a small number of cases, a tissue-expander subcutaneous reconstruction seems to have promising results. Whenever pectoralis major muscle can be spared, a conservative reconstruction might be an option
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
sLayer: a System for Multi-Layered Material Sculpting
No full textMany real world materials have a stratified structure, composed by the proximity and the interaction of multiple highly-detailed layers. Example of these materials are peeling paint, old tree bark and rusted metals. While digital sculpting is particularly well-suited to model these aged surfaces, the interaction between layers is not accounted for. We present a system for sculpting multi-layers materials where collision between layers are handled interactively while brushing meshes that scales up to the million of polygons necessary to model aged surfaces. We do so by observing that if the average mean edge length is maintained constant throughout the modeling session, we can use a single data structure, namely a uniform grid, to accelerate all the sculpting operations.We present a brush rasterization pipeline that uses this data structure for multi-layer editing.We also show that by adding a few interface tools for layer creation and selection, we can create detailed surface similar to real-world ones. To the best of our knowledge, our work is the first to show sculpting of highly-detailed, multi-layered materials in real-time
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
Fat Graft Enhanced With Adipose-Derived Stem Cells in Aesthetic Breast Augmentation: Clinical, Histological, and Instrumental Evaluation
Get PDFFat graft enhanced with adipose-derived stem cells (FG-e-ASCs) has been utilized in outcomes of radiotherapy after mastectomy, breast soft tissue defects, ulcers, and loss of substance. The authors present their experience using FG-e-ASCs in breast augmentation.Background: Fat graft enhanced with adipose-derived stem cells (FG-e-ASCs) has been utilized in outcomes of radiotherapy after mastectomy, breast soft tissue defects, ulcers, and loss of substance. The authors present their experience utilizing FG-e-ASCs in breast augmentation.Objectives: The aim of this study was to evaluate the safety and efficacy of a study group (SG) regarding utilization of FG-e-ASCs in breast augmentation for aesthetic improvement, comparing the results with a control group (CG).Methods: A total of 46 patients affected by breast hypoplasia were treated with FG-e-ASCs, comparing results with those of a CG (n = 30) treated with fat graft not enhanced with adipose-derived stem cells (FG-ne-ASCs). The preoperative evaluation included a complete clinical evaluation, a photographic assessment, magnetic resonance imaging of the soft tissue, ultrasound, and mammography. Postoperative follow-up took place at 1, 3, 7, 12, 24, and 48 weeks and then annually.Results: The patients treated with FG-e-ASCs showed 58% maintenance of the contour restoring and of 3-dimensional (3D) volume after 3 years compared with the patients of the CG treated with FG-ne-ASCs, who showed 29% maintenance. In 67.4% (n = 31) of breast augmentations treated with FG-e-ASCs, we observed a restoration of the breast contour and an increase of 10.3 mm in the 3D volume after 36 months, which was observed in only 20.0% (n = 6) of patients in the CG treated with FG-ne-ASCs. Volumetric persistence in the SG was higher than that in the CG (P < 0.0001 SG vs CG).Conclusions: Utilization of FG-e-ASCs was safe and effective in this series of cases performed
