Gender Violence: Social Structure in Latin America, the question of victim and trauma.

2014

In this article, I firstly argue that femicide is a word that indicates the psychological and physical violence against women because they belong to the female gender. I analyze in particular the femicide cases that took place in the border between Ciudad Juarez and Texas from 1993 until now, in addition to the cases on the border between Tijuana and Baja California. During this period more than 700 women were murdered in the border area between Ciudad Juarez and El Paso, still the criminals of these brutal homicides are unknown. The reason for the lack of justice can be explained through institutional corruption and the existence of a patriarchal society. Through an interdisciplinary appro…

Implementing Immersive Clustering with VR Juggler

2005

Continuous, rapid improvements in commodity hardware have allowed users of immersive visualization to employ high-quality graphics hardware, high-speed processors, and significant amounts of memory for much lower costs than would be possible with high-end, shared memory computers traditionally used for such purposes. Mimicking the features of a single shared memory computer requires that the commodity computers act in concert—namely, as a tightly synchronized cluster. In this paper, we describe the clustering infrastructure of VR Juggler that enables the use of distributed and clustered computers for the display of immersive virtual environments. We discuss each of the potential ways to syn…

A Lightweight Software Architecture for Robot Navigation and Visual Logging through Environmental Landmarks Recognition

2006

A robot architecture with real-time performance in navigation tasks is presented. The system architecture is multi-threaded with shared memory and fast message passing through static signalling. In this paper, we focused on the reactive layer components and its straightforward implementation. The proposed architecture is described with reference to an experimental setup, in which the robot task is visual logging of environmental landmarks detected on the basis of sensor readings. Our experimental results show how the robot is able to identify, make snapshots and log a set of landmarks by matching 2D geometric patterns.

Information Processing Schemes Based on Monolayer Protected Metallic Nanoclusters

2011

Nanostructures are potentially useful as building blocks to complement future electronics because of their high versatility and packing densities. The fabrication and characterization of particular nanostructures and the use of new theoretical tools to describe their properties are receiving much attention. However, the integration of these individual systems into general schemes that could perform simple tasks is also necessary because modern electronics operation relies on the concerted action of many basic units. We review here new conceptual schemes that can allow information processing with ligand or monolayer protected metallic nanoclusters (MPCs) on the basis of the experimentally de…

Signal processing and frequency-dependent associative memory based on nanoswitches

2008

A signal processing concept based on nanoscale switches whose conductance can be tuned by an external stimulus between two (ON and OFF) states is proposed and analyzed theoretically. The building block of the system is formed by a metal nanoparticle linked to two electrodes by an organic ligand and a molecular switch. When we apply an alternating potential to the system of the same frequency as the periodic variation between the ON and OFF states induced on the switch, the net charge delivered by the system exhibits a sharp resonance. This resonance can be used to process an external signal by selectively extracting the weight of the different harmonics. In addition, a frequency-dependent a…

Biopoetica

2022

Siri Hustvedt, una scrittrice che ha saputo sempre coniugare l’analisi del proprio bíos – della pro- pria “fragilità” psichica e fisica – con la teoria della narrativa, con particolare attenzione per le articolazioni della “mente narrativa”: le emozioni, l’immaginazione, la memoria. Siri Hustvedt nelle sue opere alterna profonde analisi psicologiche di carattere narrativo, in particolare autobiografico, e riflessioni saggistiche in cui centrale è il confronto con la più recente e agguerrita letteratura neuroscientifica. Siri Hustvedt, a writer who has always known how to combine the analysis of her own bios - of her psychic and physical "fragility" - with the theory of fiction, with particu…

Los archivos de distrito en Portugal: memoria administrativa, histórica y social

2018

Se presenta un análisis de la evolución histórico-jurídi ca de los Archivos de Distrito (AD) portugueses, como instituciones que asumen la salvaguarda del patrimo nio público-administrativo del país. Para ello se revisa la bibliografía más relevante sobre el tema, así como la documentación histórica, legal y política, describien do su historia desde sus orígenes y los nuevos caminos que se van trazando, en relación con el aumento de la accesibilidad a la documentación que gestionan y a las nuevas estrategias de difusión de la información entre la ciudadanía. Todo ello en el marco de las distintas ini ciativas de modernización administrativa y las nuevas tecnologías disponibles.

UV Exposure Boosts Transcutaneous Immunization and Improves Tumor Immunity: Cytotoxic T-Cell Priming through the Skin

2010

Immunologic approaches to combat cancer aim at the induction of tumor-reactive immune responses to achieve long-term protection. In this context, we recently developed a transcutaneous immunization (TCI) method using the Toll-like receptor (TLR) 7 agonist imiquimod and a peptide epitope. Application onto intact skin induces potent cytotoxic T lymphocyte (CTL) responses and protection against transplanted tumors. The purpose of this study was to explore the effects of UV irradiation on imiquimod-based TCI. Here we show that skin exposure to low-dose UV light before TCI with imiquimod strongly boosts specific CTL responses leading to memory formation and enhanced tumor protection. Toward the …

EmoTIC: Impact of a game-based social-emotional programme on adolescents

2021

[EN] Introduction Technologies provide a brilliant opportunity to promote social-emotional competences, well-being and adjustment in adolescence. Game-based programmes and serious games are digital tools that pursue an educational goal in an attractive environment for adolescents. The purpose of this study was therefore to determine the effectiveness of emoTIC, a game-based social-emotional programme designed according to Mayer, Caruso, and Salovey's model of emotional intelligence. Materials and methods The participants were 119 adolescents between 11 and 15 years, randomly assigned to the experimental group and the control group. The adolescents completed questionnaires to assess their em…
