Copias de copias: la apropiación de la apropiación en Arte Contemporáneo

Resumen Este artículo estudia la apropiación como repetición y copia. Propone un análisis del Apropiacionismo desde dos enfoques: la desviación de significados debida a cambios de temporalidad de la obra y su contexto, y la desviación generada con la aparición de la conectividad global gracias a la web 2.0, y a la materialización del Arte Digital. El artículo propone, en primer lugar, un análisis temporal de la obra After Walker Evans de Sherrie Levine, como forma de apropiación clásica derivada de la desviación contextual. En segundo, un acercamiento al mundo del Arte Digital para analizar la apropiación de la apropiación, copias de copias, como forma de remediación basada en el concepto de “Arte como bien común” y su enfoque hacia la materialización del Arte Digital. Para ello serán estudiadas las obras aftersherrielevine.com y Printwikipedia de Michael Mandiberg y Street Ghost y Overexposed Series de Paolo Cirio.Abstract This article studies appropriation as a form of repetition and copy. The text proposes an analysis of Appropriationism from two points of view: the deviation of meanings derived from changes on the temporality of the work and its context, the deviation generated by the appearance of global connectivity thanks to Web 2.0, and by the materialization of Digital Art. The article proposes, firstly, a temporal analysis of Sherrie Levine’s work After Walker Evans as a form of classic appropriation derived from the contextual deviation. Secondly, an approach to Digital Art to analyse the appropriation of appropriation, copy of copy, as a form of remediation based on the concept of "Art as a common good" and its focus on the materialization of Digital Art. Michael Mandiberg’s works Aftersherrielevine. com and Printwikipedia and Paolo Cirio’s works Street Ghost and Overexposed Series will be set to study

Telos and Repetition: Spirit and Banausia as an Art Quest

Este artículo está enmarcado en una investigación sobre el uso de la repetición como recurso plástico en arte contemporáneo. El análisis se centra en el estudio de las motivaciones que llevan a los artistas a utilizar la repetición más allá de intencionalidades conceptuales o de significación. Para ello, se estudia de forma comparativa la obra de dos artistas: Wolfgang Laib, quien desarrolla una búsqueda de la espiritualidad a través de la instauración de hábitos y rituales, e Ignacio Uriarte, quien busca la alienación mediante obras realizadas con actos burocráticos rutinarios. Este trabajo plantea el uso de la repetición partiendo desde enfoques psicológicos hasta consideraciones sobre la instauración de hábitos, mitos y ritos, y la creación de espacios delegados y campos de fuerzas, así como ideas sobre la sacralización del arte y el rol del artista en nuestra sociedad. Palabras clave: repetición; Wolfgang Laib; Ignacio Uriarte; banausia; arte y espiritualidad. This article is framed in a wider research about the use of repetition as a plastic resource in Contemporary Art. The article focuses on the study of the motivations that lead artists to use repetition, without focusing on conceptual intentions. With this purpose, the essay proposes a comparative analysis of two artists: Wolfgang Laib, who develops a search for spirituality through the use of habits and rituals. And, Ignacio Uriarte; who searches alienation working with bureaucratic routines. This text proposes the use of repetition from psychological approaches to considerations about the establishment of habits, myths and rites and the creation of delegated spaces and fields of forces, as well as ideas about the sacredness of art and the role of the artist in our society. Keywords: Repetition; Wolfgang Laib; Ignacio Uriarte; Banausia; Art and Spirituality.Facultad Experimental de Arte de la Universidad del Zulia Maracaibo - Venezuel

Medida de espesores faciales por ecografía y tomografía axial computarizada

La reconstrucción facial a partir de un cráneo es una de las líneas de investigación en Antropología Forense a nivel internacional. Hasta el momento se han llevado a cabo una serie de técnicas encaminadas a tratar de reconstruir a partir del cráneo el rostro del individuo en vida. Estos estudios se han realizado en su mayoría sobre cadáveres. En la actualidad se están tratando de establecer diferentes modelos faciales y para ello se han ampliado tanto las medidas clásicamente tomadas y se han incorporado otras nuevas, todas ellas realizadas en sujetos vivos. En nuestro estudio proponemos tomar estas medidas de partes blandas a partir de las imágenes obtenidas mediante ecografía y mediante TAC y comparar los resultados entre estas dos técnicas así como con los que han obtenidos otros autores. El material utilizado en este estudio han sido las imágenes tomadas mediante ecografía sobre 20 individuos y TAC sobre 5 de ellos, de población española actual. Los resultados obtenidos confirman la fiabilidad de ambos métodos en la medida de espesores de tejidos blandos faciales.The facial reconstruction from a skull is a line of research in forensic anthropology at international level. So far we have carried out different techniques to reconstruct the face from the skull of an individual from soft-tissue studies, conducted mostly over corpses. At the moment it is being tried to establish different models for the face and have expanded both the measures conventionally taken as other new, all made __in living subjects. In our study we propose to take these measurements of soft-tissue parts from the images obtained by ultrasound and by CT and compare the results between these two techniques and the results obtained by other authors. The materials used in this study were the images taken by ultrasound on 20 subjects and CT on 5 of them, current Spanish population. The results confirm the reliability of both methods in the measurement of facial soft tissue thickness

Risk factors for thrombotic microangiopathy in allogeneic hematopoietic stem cell recipients receiving GVHD prophylaxis with tacrolimus plus MTX or sirolimus

Post-transplant complications.-- et al.Transplantation-associated thrombotic microangiopathy (TA-TMA) is a feared complication of allogeneic hematopoietic SCT (HSCT) owing to its high mortality rate. The use of calcineurin inhibitors or sirolimus (SIR) for GVHD prophylaxis has been suggested as a potential risk factor. However, the impact of tacrolimus (TAC) and SIR combinations on the increased risk of TA-TMA is currently not well defined. We retrospectively analyzed the incidence of TA-TMA in 102 allogeneic HSCT recipients who consecutively received TAC plus SIR (TAC/SIR) (n=68) or plus MTX (TAC/MTX)±ATG (n=34) for GVHD prophylaxis. No significant differences were observed in the incidence of TA-TMA between patients receiving TAC/SIR vs TAC/MTX±ATG (7.4% vs 8.8%, P=0.8). Only grade III-IV acute GVHD, previous HSCT and serum levels of TAC >25 ng/mL were associated with a greater risk of TA-TMA. Patients developing TA-TMA have significantly poorer survival (P<0.001); however, TA-TMA ceased to be an independent prognostic factor when it was included in a multivariate model. In conclusion, the combination of TAC/SIR does not appear to pose a higher risk of TA-TMA. By contrast, we identified three different risk groups for developing TA-TMA.Peer Reviewe

Utilización de antibióticos en una farmacia comunitaria

La sociedad actual se caracteriza por una elevada intolerancia al malestar y una urgencia por solucionar molestias, incluso menores, que conduce a una demanda de utilización de los recursos disponibles, aunque no siempre se precisen, lo que influye en que el uso, entre otros, de antibióticos sea mucho mayor de lo deseable

Spin-state-dependent electrical conductivity in single-walled carbon nanotubes encapsulating spin-crossover molecules

Spin crossover (SCO) molecules are promising nanoscale magnetic switches due to their ability to modify their spin state under several stimuli. However, SCO systems face several bottlenecks when downscaling into nanoscale spintronic devices: their instability at the nanoscale, their insulating character and the lack of control when positioning nanocrystals in nanodevices. Here we show the encapsulation of robust Fe-based SCO molecules within the 1D cavities of single-walled carbon nanotubes (SWCNT). We find that the SCO mechanism endures encapsulation and positioning of individual heterostructures in nanoscale transistors. The SCO switch in the guest molecules triggers a large conductance bistability through the host SWCNT. Moreover, the SCO transition shifts to higher temperatures and displays hysteresis cycles, and thus memory effect, not present in crystalline samples. Our results demonstrate how encapsulation in SWCNTs provides the backbone for the readout and positioning of SCO molecules into nanodevices, and can also help to tune their magnetic properties at the nanoscale.Marie Skłodowska-Curie Actions 74657Programa de Atracción del Talento Investigador 2017-T1/IND-5562Ministerio de Economia, Industria y Competitividad CTQ2017-86060-P, PID2019-111479GB-100, MAT 2017-8225, GC2018-101689-B-I00Consejo Europeo de Investigación ERC-StG-307609, ERC-PoC-842606Comunidad Autónoma de Madrid MAD2D-CM S2013/ MIT-3007, PEJD-2017-PRE/IND-4037, Y2018/NMT- 4783NANOMAGCOST P2018/ NMT-432

Epsilon iron oxide: Origin of the high coercivity stable low Curie temperature magnetic phase found in heated archeological materials

The identification of epsilon iron oxide (-Fe2O3) as the low Curie temperature high coercivity stable phase (HCSLT) carrying the remanence in heated archeological samples has been achieved in samples from two archeological sites that exhibited the clearest evidence of the presence of the HCSLT. This uncommon iron oxide has been detected by Confocal Raman Spectroscopy (CRS) and characterized by rock magnetic measurements. Large numbers of -Fe2O3 microaggregates (in CO) or isolated clusters (in HEL) could be recognized, distributed over the whole sample, and embedded within the ceramic matrix, along with hematite and pseudobrookite and with minor amounts of anatase, rutile, and maghemite. Curie temperature estimates of around 170 degrees C for CO and 190 degrees C for HEL are lower than for pure, synthetic -Fe2O3 (227 degrees C). This, together with structural differences between the Raman spectra of the archeologically derived and synthetic samples, is likely due to Ti substitution in the -Fe2O3 crystal lattice. The -Fe2O3--Fe2O3--Fe2O3 transformation series has been recognized in heated archeological samples, which may have implications in terms of their thermal history and in the factors that govern the formation of -Fe2O3

Short-Term Pilot Study to Evaluate the Impact of Salbi Educa Nutrition App in Macronutrients Intake and Adherence to the Mediterranean Diet: Randomized Controlled Trial

Promoting a healthy diet is a relevant strategy for preventing non-communicable diseases. This study aims to evaluate the impact of an innovative tool, the SAlBi educa nutrition app, in primary healthcare dietary counseling to improve dietary profiles as well as adherence to the Mediterranean diet. A multi-center randomized control trial comprising 104 participants was performed. Both control (n = 49) and intervention (n = 55) groups attended four once-weekly sessions focusing on healthy eating habits and physical activity, over one month. As well as attending the meetings, the intervention group used the app, which provides self-monitoring and tailored dietary advice based on the Mediterranean diet model. In a second intervention (one arm trial), the potential of SAlBi educa was evaluated for three months during the COVID-19 pandemic. At 4 weeks, the intervention group had significantly increased their carbohydrate intake (7.7% (95% CI: 0.16 to 15.2)) and decreased their total fat intake (−5.7% (95% CI: −10.4 to −1.15)) compared to the control group. Significant differences were also found for carbohydrates (3.5% (95% CI: −1.0 to 5.8)), total fats (−5.9% (95% CI: −8.9 to −3.0)), fruits and vegetables (266.3 g/day (95% CI: 130.0 to 402.6)), legumes (7.7g/day (95% CI: 0.2 to 15.1)), starchy foods (36.4 g/day (95% CI: 1.1 to 71.7)), red meat (−17.5 g/day (95% CI: −34.0 to −1.1)), and processed meat (−6.6 g/day (95% CI: −13.1 to −0.1)) intakes during the COVID-19 pandemic. SAlBi educa is a useful tool to support nutrition counseling in primary healthcare, including in special situations such as the COVID-19 pandemic.
