Mexican B(order) movies en Tijuana: ironía como crítica a la hegemonía en las fotos de Fabio Cuttica

The intention of this work is to analyze the photographic reportage “Mexican (B)order movies” by Fabio Cuttica as a product of the imaginary about violence in Mexico. By means of a theoretical approach focusing on the use of the device of irony, we aim to understand the various strategies with which a journalistic photo is able to build, deconstruct or criticize the imaginary about violence as well as the hegemonic discourses on narcoculture.La intención de este trabajo es analizar el reportaje fotográfico “Mexican (B)order movies” de Fabio Cuttica en tanto producto del imaginario sobre la violencia en México. A través de un enfoque teórico que se centra en el uso del dispositivo de la ironía, el intento es entender cómo funcionan las diversas estrategias con las que una foto periodística construye, deconstruye o critica el imaginario y los discursos hegemónicos sobre la violencia en general y sobre la narcocultura en particular

NARCOCULTURAS La construcción de un imaginario entre discurso hegemónico y nuevas narrativas de la violencia

El objetivo de este dossier es explorar las implicaciones del aparato discursivo del “narco” en sus dimensiones culturales, sociales, políticas, literarias, artísticas, geográficas, antropológicas, históricas, fotográficas, audiovisuales y de la producción material de la cultura para  ofrecer una mirada crítica que ayude a darle la justa dimensión a un concepto que ha sido y sigue siendo central en la explicación de relaciones de poder y violencia en el continente latinoamericano, también en su relación con el resto del mundo

A framework for culture-aware robots based on fuzzy logic

Cultural adaptation, i.e., the matching of a robot's behaviours to the cultural norms and preferences of its user, is a well known key requirement for the success of any assistive application. However, culture-dependent robot behaviours are often implicitly set by designers, thus not allowing for an easy and automatic adaptation to different cultures. This paper presents a method for the design of culture-aware robots, that can automatically adapt their behaviour to conform to a given culture. We propose a mapping from cultural factors to related parameters of robot behaviours which relies on linguistic variables to encode heterogeneous cultural factors in a uniform formalism, and on fuzzy rules to encode qualitative relations among multiple variables. We illustrate the approach in two practical case studies

Narrativas hegemónicas de la violencia : el crimen organizado y el narcotráfico entre el periodismo y las ficciones televisivas

Los relatos que buscan explicar fenómenos como el narcotráfico en México o Colombia, o la camorra en Italia suelen enfocarse en el papel central que el llamado "crimen organizado" desempeñaría en la generación de la violencia. Las narrativas binarias en torno al crimen organizado son difundidas desde instancias gubernamentales y establecen una clara distinción entre los grupos criminales y un estado que intenta someterlos a través de una política "de seguridad nacional". Esta forma de comprender el contexto constituye una narrativa hegemónica que se difunde acríticamente a través de ciertos trabajos periodísticos publicados en medios generalistas, pero también en algunas crónicas muy celebradas que privilegian sus recursos literarios por encima del rigor investigativo. Partiendo del caso mexicano, este artículo propone una revisión de las repercusiones de estas narrativas periodísticas en las series televisivas de ficción Gomorra (2014), Narcos (2015) y El Chapo (2017), series que coinciden en enunciarse a sí mismas como basadas en hechos periodísticamente registrados. Desde una perspectiva crítica, este análisis busca explorar los modos en que las narrativas de ficción naturalizan un discurso hegemónico de la violencia generado en ámbitos gubernamentales y empresariales, y reproducido acríticamente, para evidenciar cómo la ficción televisiva termina llenando las partes de la historia ausentes en el periodismo. La combinación de documento, periodismo y ficción confiere un sentido narrativo a la trama televisiva, pero a la vez coadyuva en la construcción de un imaginario colectivo que deforma la historia y fortalece el discurso securitario construido desde el poder.The stories that seek to explain phenomena such as drug trafficking in Mexico or Colombia, or the Camorra in Italy, often focus on the central role that so-called "organised crime" plays in the generation of violence. The binary narratives on organised crime are disseminated by government agencies and establish a clear distinction between criminal groups and a state that attempts to suppress them through "national security" policy. This manner of understanding the context becomes a hegemonic narrative that is uncritically diffused by certain journalistic works published in the general media, but also by some celebrated pieces of narrative journalism that privilege their literary resources above their investigative rigour. Based on the Mexican case, this paper proposes a review of the repercussions of these journalistic narratives in the fictional television series Gomorra (2014), Narcos (2015) and El Chapo (2017), which coincide in enunciating themselves as based on journalistically- recorded facts. From a critical perspective, this analysis seeks to explore the ways fictional narratives naturalise a hegemonic discourse of violence, which is generated in government and business circles, and which is uncritically reproduced, in order to evidence how television fiction ends up filling in parts of the story that are absent in the journalism. The combination of document, journalism and fiction confers a narrative sense to the television plot, but at the same time contributes to the construction of a collective imaginary that deforms history and strengthens the securitarian discourse built from power.Els relats que busquen explicar fenòmens com el narcotràfic a Mèxic o a Colòmbia, o la camorra a Itàlia solen enfocar-se en el paper central que l'anomenat "crim organitzat" desenvoluparia en la generació de la violència. Les narratives binàries entorn del crim organitzat es difonen des d'instàncies governamentals i estableixen una clara distinció entre els grups criminals i un estat que intenta sotmetre'ls a través d'una política "de seguretat nacional". Aquesta manera de comprendre el context constitueix una narrativa hegemònica que es difon acríticament a través de certs treballs periodístics publicats en mitjans generalistes, però també en algunes cròniques molt celebrades que privilegien els seus recursos literaris per damunt del rigor investigatiu. Partint del cas mexicà, aquest article proposa una revisió de les repercussions d'aquestes narratives periodístiques en les sèries televisives de ficció Gomorra (2014), Narcos (2015) i El Chapo (2017), sèries que coincideixen a enunciar-se a si mateixes com basades en fets periodísticament registrats. Des d'una perspectiva crítica, aquesta anàlisi busca explorar la manera en què les narratives de ficció naturalitzen un discurs hegemònic de la violència generat en àmbits governamentals i empresarials, i reproduït acríticament, per evidenciar com la ficció televisiva acaba omplint les parts de la història absents en el periodisme. La combinació de document, periodisme i ficció confereix un sentit narratiu a la trama televisiva, però alhora coadjuva en la construcció d'un imaginari col·lectiu que deforma la història i enforteix el discurs securitari construït des del poder

A method to search for long duration gravitational wave transients from isolated neutron stars using the generalized FrequencyHough

We describe a method to detect gravitational waves lasting $O(hours-days)$ emitted by young, isolated neutron stars, such as those that could form after a supernova or a binary neutron star merger, using advanced LIGO/Virgo data. The method is based on a generalization of the FrequencyHough (FH), a pipeline that performs hierarchical searches for continuous gravitational waves by mapping points in the time/frequency plane of the detector to lines in the frequency/spindown plane of the source. We show that signals whose spindowns are related to their frequencies by a power law can be transformed to coordinates where the behavior of these signals is always linear, and can therefore be searched for by the FH. We estimate the sensitivity of our search across different braking indices, and describe the portion of the parameter space we could explore in a search using varying fast Fourier Transform (FFT) lengths.Comment: 15 figure

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

Al borde de lo indecible. Ironia y regimenes de visibilidad en el fotoperiodismo de Fabio Cuttica

En esta tesis concentro mi atención en observar, describir y analizar los modos en que pueden cuestionarse o incluso subvertirse los regímenes de visibilidad hegemónicos del concepto de frontera en México en la imagen fotoperiodística que usa la ironía como estrategia discursiva. De esta forma será posible explorar alternativas discursivas que desde la subalternidad tengan la capacidad de evidenciar características y contradicciones de la industria de los medios periodísticos hegemónicos. Como periodista e investigador la intención es entender de qué forma es posible cuestionar la hegemonía desde el fotoperiodismo, estando el fotoperiodismo presionado por unas industrias mediáticas que tienen intereses comerciales, con agendas políticas definidas. Es decir, si es posible y en qué modo puede ejercerse una crítica al sistema desde el propio sistema
