Amexica Skin: an immersive digital device, at the heart of the Mexican-American border Amexica Skin: un dispositivo digital de inmersión, el corazón de la frontera mexicano-americana

A través del espacio abierto de la obra de AmeXica sKin, cuestiono mi compromiso como artista en la historia: ¿qué forma dar a mi testimonio, a mi punto de vista sobre elmundo y sobre la travesía al cruzar la frontera mexicano-americana acompañando a los inmigrantes, fuera de los clichés transmitidos por los medios de comunicación, la política, las costumbres culturales y estéticas? Escogí imaginar el cruce de la frontera como una sucesión de pruebas, una imagen simbólica de un laberinto, la materialización de la amenaza de encontrarse con la muerte, pero también de la búsqueda del sentido de la vida. La metáfora de la frontera como piel, y el concepto de la banda de Möbius, estructuran la forma del dispositivo. Este trabajo, un intercambio de flujos y experiencias sensoriales, se encuentra en el corazón de las cuestiones antropológicas y estéticas que ponen de manifiesto la transformación de las formas de movilidad y migraciones humanas contemporáneas

Art therapy and atopic dermatitis : making the invisible visible

By combining qualitative and quantitative research methodologies, the present study attempts to measure the impact art therapy might have on psychosomatic skin disorders and its symptoms. The " Visible-Invisible " model developed for this research is introduced and demonstrated through the case material of a woman living with eczema. The use of reliable tests such as the Beck Depression Inventory (BDI), the Anxiety State Traits Assessment (ASTA), the Millon Clinical Multiaxial Inventory--III(MCNI-III) and the SF-36 Health Survey are used to measure the effects of the treatment onto the eczematous symptoms and related factors such as anxiety. Following art therapy treatment, the Post-test scores indicated lower anxiety level and higher vitality, social functioning and mental health as rated by the participant. Although some of the results were found significant, they should not be generalized to the population living with psychosomatic skin disorders

Born Digital Records of Mexican Indigenous People: A Proposal to Preserve Sound and Audiovisual Documents of Raramuri ́s Culture

Each day increases the amount of digital born sound and audiovisual documents as collections in libraries, archives and museums. However are unaware how these collections must be preserved for the future. Therefore, the risk of loss is increased. All types of sound and audiovisual recordings in risk if they are not documented and preserved properly, highlights the recordings of the indigenous peoples. This is serious phenomenon because with the loss of an indigenous language will be lost knowledge, worldview, and the way of understanding the world of a social group. The diversity of the indigenous languages of Mexico as cultural heritage and as information resource, is under threat. Indeed, it has been noted that when concluded this century half of 6 thousand languages spoken in the world be it extinguished (UNESCO, 2003). Of these the most vulnerable are those who speak are in indigenous communities. Of the various strategies that have been proposed to preserve indigenous languages, emphasizes the recording of music, rituals, stories, among others. For this reason, sound and audiovisual documents of the indigenous peoples are valuable resources of information. Recordings of indigenous peoples of Mexico have a high documentary value, precisely as endangered documents. Therefore, this paper will present the progress of the project Digital preservation of born digital audiovisual and sound collections developed by UNAM and the École européenne Supérieure de l\u27image, Poitiers France; and sponsored by the PAPIIT (Programa de Apoyo a Proyectos de Investigación e Innovación Tecnológica). This international project will focus on addressing one of the priority issues in libraries and archives: the preservation of sound and audiovisual collections digital born. This project responds to the global trend characterized by the search for solutions to ensure that the sounds and images that reflect our identity should be preserved in the future

Untangling methodological and scale considerations in growth and productivity trend estimates of Canada’s forests

In view of the economic, social and ecological importance of Canada's forest ecosystems, there is a growing interest in studying the response of these ecosystems to climate change. Accurate knowledge regarding growth trajectories is needed for both policy makers and forest managers to ensure sustainability of the forest resource. However, results of previous analyses regarding the sign and magnitude of trends have often diverged. The main objective of this paper was to analyse the current state of scientific knowledge on growth and productivity trends in Canada's forests and provide some explanatory elements for contrasting observations. The three methods that are commonly used for assessments of tree growth and forest productivity (i.e. forest inventory data, tree-ring records, and satellite observations) have different underlying physiological assumptions and operate on different spatiotemporal scales, which complicates direct comparisons of trend values between studies. Within our systematic review of 44 peer-reviewed studies, half identified increasing trends for tree growth or forest productivity, while the other half showed negative trends. Biases and uncertainties associated with the three methods may explain some of the observed discrepancies. Given the complexity of interactions and feedbacks between ecosystem processes at different scales, researchers should consider the different approaches as complementary, rather than contradictory. Here, we propose the integration of these different approaches into a single framework that capitalizes on their respective advantages while limiting associated biases. Harmonization of sampling protocols and improvement of data processing and analyses would allow for more consistent trend estimations, thereby providing greater insight into climate-change related trends in forest growth and productivity. Similarly, a more open data-sharing culture should speed-up progress in this field of research

Stable isotope characterization of pedogenic and lacustrine carbonates from the Chinese Tian Shan: constraints on the Mesozoic - Lower Cenozoic palaeo-environmental evolution

International audienceIn the Mesozoic–Cenozoic continental deposits of the Tian Shan area, two main levels containing pedogenic carbonates have been identified on both the southern and northern foothills of the range: one in the Upper Jurassic series and one in the Upper Cretaceous–Lower Palaeocene series. In order to reconstruct the palaeoenvironmental and palaeotopographic characteristics of the Tian Shan area during these two periods, we measured the oxygen and carbon isotope composition of these pedogenic carbonates (calcrete and nodules). The stable isotope compositions are homogeneous: most δ18O values are between 21 and 25‰ and most δ13C values are between −4 and −6‰. No distinction can be made between the calcrete and nodule isotopic compositions. The constancy of isotopic values across the Tian Shan is evidence of a development of these calcification features in similar palaeoenvironmental conditions. The main inference is that no significant relief existed in that area at the Cretaceous−Palaeogene boundary, implying that most of the present relief developed later, during the Cenozoic. In addition to the pedogenic carbonates, few beds of limestones interstratified in the Jurassic series of the southern foothills display oxygen and carbon isotope compositions typical of lacustrine carbonates, ruling out brackish water incursion at that period in the regio

Review: Adaptation of Beneficial Propionibacteria, Lactobacilli, and Bifidobacteria Improves Tolerance Toward Technological and Digestive Stresses

This review deals with beneficial bacteria, with a focus on lactobacilli, propionibacteria, and bifidobacteria. As being recognized as beneficial bacteria, they are consumed as probiotics in various food products. Some may also be used as starters in food fermentation. In either case, these bacteria may be exposed to various environmental stresses during industrial production steps, including drying and storage, and during the digestion process. In accordance with their adaptation to harsh environmental conditions, they possess adaptation mechanisms, which can be induced by pretreatments. Adaptive mechanisms include accumulation of compatible solutes and of energy storage compounds, which can be largely modulated by the culture conditions. They also include the regulation of energy production pathways, as well as the modulation of the cell envelop, i.e., membrane, cell wall, surface layers, and exopolysaccharides. They finally lead to the overexpression of molecular chaperones and of stress-responsive proteases. Triggering these adaptive mechanisms can improve the resistance of beneficial bacteria toward technological and digestive stresses. This opens new perspectives for the improvement of industrial processes efficiency with regard to the survival of beneficial bacteria. However, this bibliographical survey evidenced that adaptive responses are strain-dependent, so that growth and adaptation should be optimized case-by-case

Philadelphie

1. Preamble In 2018, we succeeded in identifying two significant quarters in the urban area of Philadelphia: a quarter of potters (sector 37) and a quarter of storehouses (sector 15, sector 40). Their remains are limited at relatively early Ptolemaic strata (mid. 3rd–2nd century BC). Two other quarters, though with less distinctive and coherent traits, also emerged: a quarter of water reservoirs (S12, S13, S39) still uncertainly dated, as well as a quarter (S38) which may or may not be relate..
