Celebrities, violencia de género y derechos de las mujeres: ¿hacia una transformación del marco de reconocimiento?

Introducción. Ante los límites que presenta el actual marco de reconocimiento de la violencia de género, el presente trabajo analiza las posibilidades que abre la acción de celebrities en la transformación de este marco y en relación a la lucha por los derechos de las mujeres. Para ello proponemos el concepto de ethical witnessing. Metodología. Se propone un modelo de análisis a través de la operacionalización de dicho concepto para el estudio de prácticas representacionales que puedan desestabilizar los actuales parámetros de representación en aras de la resignificación del sujeto-víctima de la violencia. Las cuatro dimensiones de análisis son: el tipo de relación que se genera entre el sujeto-víctima y quien atestigua; el grado de transgresión de los modelos reificados de la identificación del sujeto-víctima; la focalización en la capacidad de agencia; y las conexiones que se establecen con las luchas por los derechos de las mujeres y con otras luchas. Este modelo se aplica a tres casos de estudio: las actuaciones musicales de Beyoncé, la entrevista periodística realizada a Carmen Maura y la campaña mediática de Emma Watson. Resultados. Se discuten las posibilidades de las prácticas discursivas que se incardinan en los principios del postfeminismo. Frente a la identidad de la mujer como víctima emerge la de la mujer exitosa que compatibiliza vindicación feminista y lucha contra la violencia de género con consumismo, materialismo y capitalismo. Esto permite desestabilizar la narrativa fijada sobre la violencia pero no llega a constituir una re-significación del marco en tanto que puede quedar co-optado por la ‘economía de las celebrities’, ser absorbido por el feminismo liberal o estar desvinculado de la lucha colectiva, lo que dificulta la aprehensión del carácter compartido de la vulnerabilidad.Introduction. Due to the limitations of the current framework of recognition of gender-based violence, this article analyses the possibilities of the actions performed by celebrities in the transformation of such framework and in the fight for women’s rights. To this end, we propose the concept of “ethical witnessing”. Methods. The study proposes an analytical model based on the operationalisation of this concept applied to the examination of the representational practices that may destabilise the current hegemonic configuration and re-signify the subject-victim relationship of violence. The four dimensions of analysis are: the relations generated between the subject-victim and the witness; the degree of transgression of the reified representational models of the subject-victim; the focus on agency; and the connection with women’s fights for their rights and other social movements. This model is applied to three case studies: Beyoncé’s musical performances; the interview with actress Carmen Maura, and Emma Watson’s #HeForShe media campaign. Results. The study discusses the possibilities of the discursive practices stemming from postfeminist principles. A new image emerges to contrast the image of women as victims: the image of successful women who find a balance between feminist vindications and the fight against gender-based violence with consumerism, materialism and capitalism. This image enables the destabilisation of the narrative about violence, but it does not constitute a re-signification of the framework of recognition, as it can be co-opted by the “celebrity economy”, can be absorbed by liberal feminism, or can be disassociated from the collective fight, which complicates the comprehension of the shared nature of vulnerability

The MUSE-Wide Survey: A first catalogue of 831 emission line galaxies

We present a first instalment of the MUSE-Wide survey, covering an area of 22.2 arcmin$^2$ (corresponding to $\sim$20% of the final survey) in the CANDELS/Deep area of the Chandra Deep Field South. We use the MUSE integral field spectrograph at the ESO VLT to conduct a full-area spectroscopic mapping at a depth of 1h exposure time per 1 arcmin$^2$ pointing. We searched for compact emission line objects using our newly developed LSDCat software based on a 3-D matched filtering approach, followed by interactive classification and redshift measurement of the sources. Our catalogue contains 831 distinct emission line galaxies with redshifts ranging from 0.04 to 6. Roughly one third (237) of the emission line sources are Lyman $\alpha$ emitting galaxies with $3 < z < 6$, only four of which had previously measured spectroscopic redshifts. At lower redshifts 351 galaxies are detected primarily by their [OII] emission line ($0.3 \lesssim z \lesssim 1.5$), 189 by their [OIII] line ($0.21 \lesssim z \lesssim 0.85$), and 46 by their H$\alpha$ line ($0.04 \lesssim z \lesssim 0.42$). Comparing our spectroscopic redshifts to photometric redshift estimates from the literature, we find excellent agreement for $z<1.5$ with a median $\Delta z$ of only $\sim 4 \times 10^{-4}$ and an outlier rate of 6%, however a significant systematic offset of $\Delta z = 0.26$ and an outlier rate of 23% for Ly$\alpha$ emitters at $z>3$. Together with the catalogue we also release 1D PSF-weighted extracted spectra and small 3D datacubes centred on each of the 831 sources.Comment: 24 pages, 14 figures, accepted for publication in A&A, data products are available for download from http://muse-vlt.eu/science/muse-wide-survey/ and later via the CD

The MUSE-Wide Survey: Survey Description and First Data Release

We present the MUSE-Wide survey, a blind, 3D spectroscopic survey in the CANDELS/GOODS-S and CANDELS/COSMOS regions. Each MUSE-Wide pointing has a depth of 1 hour and hence targets more extreme and more luminous objects over 10 times the area of the MUSE-Deep fields (Bacon et al. 2017). The legacy value of MUSE-Wide lies in providing "spectroscopy of everything" without photometric pre-selection. We describe the data reduction, post-processing and PSF characterization of the first 44 CANDELS/GOODS-S MUSE-Wide pointings released with this publication. Using a 3D matched filtering approach we detected 1,602 emission line sources, including 479 Lyman-$\alpha$ (Lya) emitting galaxies with redshifts $2.9 \lesssim z \lesssim 6.3$. We cross-match the emission line sources to existing photometric catalogs, finding almost complete agreement in redshifts and stellar masses for our low redshift (z < 1.5) emitters. At high redshift, we only find ~55% matches to photometric catalogs. We encounter a higher outlier rate and a systematic offset of $\Delta$z$\simeq$0.2 when comparing our MUSE redshifts with photometric redshifts. Cross-matching the emission line sources with X-ray catalogs from the Chandra Deep Field South, we find 127 matches, including 10 objects with no prior spectroscopic identification. Stacking X-ray images centered on our Lya emitters yielded no signal; the Lya population is not dominated by even low luminosity AGN. A total of 9,205 photometrically selected objects from the CANDELS survey lie in the MUSE-Wide footprint, which we provide optimally extracted 1D spectra of. We are able to determine the spectroscopic redshift of 98% of 772 photometrically selected galaxies brighter than 24th F775W magnitude. All the data in the first data release - datacubes, catalogs, extracted spectra, maps - are available on the website https://musewide.aip.de. [abridged]Comment: 25 pages 15+1 figures. Accepted, A&A.

Prevalence of and Risk Factors for Biliary Carriage of Bacteria Showing Worrisome and Unexpected Resistance Traits

Data on biliary carriage of bacteria and, specifically, of bacteria with worrisome and unexpected resistance traits (URB) are lacking. A prospective study (April 2010 to December 2011) was performed that included all patients admitted for<48 h for elective laparoscopic cholecystectomy in a Spanish hospital. Bile samples were cultured and epidemiological/clinical data recorded. Logistic regression models (stepwise) were performed using bactobilia or bactobilia by URB as dependent variables. Models (P< 0.001) showing the highest R2 values were considered. A total of 198 patients (40.4% males; age, 55.3 17.3 years) were included. Bactobilia was found in 44 of them (22.2%). The presence of bactobilia was associated (R2 Cox, 0.30) with previous biliary endoscopic retrograde cholangiopancreatography (ERCP) (odds ratio [OR], 8.95; 95% confidence interval [CI], 2.96 to 27.06; P< 0.001), previous admission (OR, 2.82; 95% CI, 1.10 to 7.24; P 0.031), and age (OR, 1.09 per year; 95% CI, 1.05 to 1.12; P< 0.001). Ten out of the 44 (22.7%) patients with bactobilia carried URB: 1 Escherichia coli isolate (CTX-M), 1 Klebsiella pneumoniae isolate (OXA-48), 3 high-level gentamicin-resistant enterococci, 1 vancomycin-resistant Enterococcus isolate, 3 Enterobacter cloacae strains, and 1 imipenem-resistant Pseudomonas aeruginosa strain. Bactobilia by URB (versus those by non-URB) was only associated (R2 Cox, 0.19) with previous ERCP (OR, 11.11; 95% CI, 1.98 to 62.47; P 0.006). For analyses of patients with bactobilia by URB versus the remaining patients, previous ERCP (OR, 35.284; 95% CI, 5.320 to 234.016; P<0.001), previous intake of antibiotics (OR, 7.200; 95% CI, 0.962 to 53.906; P 0.050), and age (OR, 1.113 per year of age; 95% CI, 1.028 to 1.206; P 0.009) were associated with bactobilia by URB (R2 Cox, 0.19; P<0.001). Previous antibiotic exposure (in addition to age and previous ERCP) was a risk driver for bactobilia by URB. This may have implications in prophylactic/therapeutic measures

Boards of directors in SMEs: An empirical evidence of board task performance

This paper seeks to provide a better understanding of what makes boards effective. We analyse the relationships between board demography and company performance and between working structures and board tasks in small and medium-sized enterprises (SMEs). We test our hypotheses on a sample of 307 Spanish SMEs. The main empirical result is the negative impact that the proportion of outside directors and the board size have on firm performance. We also find a negative impact of outsiders’ presence and a positive impact of director tenure on the board’s service role. Our analysis of the role of board control highlights the negative relationship between this variable and CEO tenure

No More Active Galactic Nuclei in Clumpy Disks Than in Smooth Galaxies at z~2 in CANDELS / 3D-HST

We use CANDELS imaging, 3D-HST spectroscopy, and Chandra X-ray data to investigate if active galactic nuclei (AGNs) are preferentially fueled by violent disk instabilities funneling gas into galaxy centers at 1.3<z<2.4. We select galaxies undergoing gravitational instabilities using the number of clumps and degree of patchiness as proxies. The CANDELS visual classification system is used to identify 44 clumpy disk galaxies, along with mass-matched comparison samples of smooth and intermediate morphology galaxies. We note that, despite being being mass-matched and having similar star formation rates, the smoother galaxies tend to be smaller disks with more prominent bulges compared to the clumpy galaxies. The lack of smooth extended disks is probably a general feature of the z~2 galaxy population, and means we cannot directly compare with the clumpy and smooth extended disks observed at lower redshift. We find that z~2 clumpy galaxies have slightly enhanced AGN fractions selected by integrated line ratios (in the mass-excitation method), but the spatially resolved line ratios indicate this is likely due to extended phenomena rather than nuclear AGNs. Meanwhile the X-ray data show that clumpy, smooth, and intermediate galaxies have nearly indistinguishable AGN fractions derived from both individual detections and stacked non-detections. The data demonstrate that AGN fueling modes at z~1.85 - whether violent disk instabilities or secular processes - are as efficient in smooth galaxies as they are in clumpy galaxies.Comment: ApJ accepted. 17 pages, 17 figure

Stars, gas, and star formation of distant post-starburst galaxies

We present a comprehensive multi-wavelength study of 5 poststarburst galaxies with $M_\ast > 10^{11} M_\odot$ at $z\sim 0.7$, examining their stars, gas, and current and past star-formation activities. Using optical images from the Subaru telescope and Hubble Space Telescope, we observe a high incidence of companion galaxies and low surface brightness tidal features, indicating that quenching is closely related to interactions between galaxies. From optical spectra provided by the LEGA-C survey, we model the stellar continuum to derive the star-formation histories and show that the stellar masses of progenitors ranging from $2\times10^9 M_\odot$ to $10^{11} M_\odot$, undergoing a burst of star formation several hundred million years prior to observation, with a decay time scale of $\sim100$ million years. Our ALMA observations detect CO(2-1) emission in four galaxies, with the molecular gas spreading over up to $>1"$, or $\sim10$ kpc, with a mass of up to $\sim2 \times10^{10} M_\odot$. However, star-forming regions are unresolved by either the slit spectra or 3~GHz continuum observed by the Very Large Array. Comparisons between the star-formation rates and gas masses, and the sizes of CO emission and star-forming regions suggest a low star-forming efficiency. We show that the star-formation rates derived from IR and radio luminosities with commonly-used calibrations tend to overestimate the true values because of the prodigious amount of radiation from old stars and the contribution from AGN, as the optical spectra reveal weak AGN-driven outflows.Comment: Accepted by Ap

Risk assessment for the spread of Serratia marcescens within dental-unit waterline systems using Vermamoeba vermiformis

Vermamoeba vermiformis is associated with the biofilm ecology of dental-unit waterlines (DUWLs). This study investigated whether V. vermiformis is able to act as a vector for potentially pathogenic bacteria and so aid their dispersal within DUWL systems. Clinical dental water was initially examined for Legionella species by inoculating it onto Legionella selective-medium plates. The molecular identity/profile of the glassy colonies obtained indicated none of these isolates were Legionella species. During this work bacterial colonies were identified as a non-pigmented Serratia marcescens. As the water was from a clinical DUWL which had been treated with Alpron™ this prompted the question as to whether S. marcescens had developed resistance to the biocide. Exposure to Alpron™ indicated that this dental biocide was effective, under laboratory conditions, against S. marcescens at up to 1x108 colony forming units/millilitre (cfu/ml). V. vermiformis was cultured for eight weeks on cells of S. marcescens and Escherichia coli. Subsequent electron microscopy showed that V. vermiformis grew equally well on S. marcescens and E. coli (p = 0.0001). Failure to detect the presence of S. marcescens within the encysted amoebae suggests that V. vermiformis is unlikely to act as a vector supporting the growth of this newly isolated, nosocomial bacterium
