Palabras que liberan: Identidad y expresión de jóvenes en contexto de encierro

Este Trabajo Integrador Final de Reflexión de Prácticas en Comunicación surge de la necesidad de realizar un análisis colectivo sobre una experiencia concreta que transitamos como estudiantes, a partir de una intervención de comunicación en una institución de encierro. Al comenzar esta práctica, enmarcada en la cursada de una materia de la Orientación Planificación Comunicacional de la Facultad de Periodismo y Comunicación (UNLP), pudimos observar que la Unidad Penitenciaria N°45 no ofrece espacios para promover procesos de comunicación interpersonales en lxs jóvenes allí alojados. Es por esto que, a partir de nuestro trabajo como talleristas, decidimos intervenir generando el Taller “Cultura y Expresión”, como un espacio de gestión de la comunicación entre lxs jóvenes, entendiendo a la comunicación como una herramienta de construcción de nuevos sentidos y prácticas sociales. Al mismo tiempo, comprendiendo que la cultura es inseparable de la comunicación y a esta relación como un proceso histórico-social. A partir de la práctica, entendemos a lxs jóvenes que se encuentran en contexto de encierro como personas que están atravesadas por diversas vulnerabilidades y discursos estigmatizantes que se generan desde las instituciones penitenciarias, educativas,los medios de comunicación y demás sectores de la sociedad, que influyen en los modos de construir sus identidades y que ponen en tensión la situación y el destino de lxs mismos desde diferentes tipos de discriminación: desde lo social, lo laboral, y el acceso a los derechos como salud, educación y alimentación. En este sentido, como comunicadorxs consideramos que es importante que la comunicación sea también, en contexto de encierro, una herramienta emancipadora, que puedan poner en práctica mientras se encuentran dentro del sistema carcelario, como así también, para su vida cotidiana al recuperar la libertad. Por lo tanto, a partir del Taller, generamos un espacio de encuentro, de escucha, de circulación de la palabra, de estimulación de la expresión y de problematización de temas de interés desde la realización de debates y de diferentes actividades. Decidimos afrontar este Trabajo Integrador Final (TIF) de Reflexión de Prácticas con el objetivo de sistematizar la práctica y analizar las producciones discursivas realizadas por lxs jóvenes para reconocer modos de construir sus identidades. Al mismo tiempo, decidimos optar por esta modalidad de TIF, con el propósito de que la experiencia pueda ser recuperada,no sólo como un objeto de análisis y reflexión, sino también como un material teórico y práctico. Al respecto, producimos un documento descriptivo con la intención de aportar una herramienta para futuras intervenciones en territorios similares. Creemos que esta práctica pre-profesional fue necesaria para pensar desde qué lugar queremos posicionarnos como comunicadorxs sociales. Además, creemos que la carrera en Comunicación Social con orientación en Planificación Comunicacional nos brinda las herramientas teórico-metodológicas necesarias para lograr identificar los discursos identitarios que circulan entre lxs jóvenes y, por lo tanto, nos posibilita su análisis y reflexión crítica.Facultad de Periodismo y Comunicación Socia

Scientists’ Warning to Humanity: Rapid degradation of the world\u27s large lakes

Large lakes of the world are habitats for diverse species, including endemic taxa, and are valuable resources that provide humanity with many ecosystem services. They are also sentinels of global and local change, and recent studies in limnology and paleolimnology have demonstrated disturbing evidence of their collective degradation in terms of depletion of resources (water and food), rapid warming and loss of ice, destruction of habitats and ecosystems, loss of species, and accelerating pollution. Large lakes are particularly exposed to anthropogenic and climatic stressors. The Second Warning to Humanity provides a framework to assess the dangers now threatening the world\u27s large lake ecosystems and to evaluate pathways of sustainable development that are more respectful of their ongoing provision of services. Here we review current and emerging threats to the large lakes of the world, including iconic examples of lake management failures and successes, from which we identify priorities and approaches for future conservation efforts. The review underscores the extent of lake resource degradation, which is a result of cumulative perturbation through time by long-term human impacts combined with other emerging stressors. Decades of degradation of large lakes have resulted in major challenges for restoration and management and a legacy of ecological and economic costs for future generations. Large lakes will require more intense conservation efforts in a warmer, increasingly populated world to achieve sustainable, high-quality waters. This Warning to Humanity is also an opportunity to highlight the value of a long-term lake observatory network to monitor and report on environmental changes in large lake ecosystems

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 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

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
