Pedofilia em museus: Quando o antigo conceito de pânico moral se faz presente

Tendo como material de análise a reação que levou ao fechamento da exposição Queermuseu: Cartografias da diferença na arte brasileira, em Porto Alegre, o texto tem como objetivo falar sobre pedofilia a partir do conceito de pânico moral. Para isso, faço algumas considerações a respeito desse conceito, inserindo-o na nova dinâmica do século XXI. Em seguida, busco responder qual foi, efetivamente, a questão de fundo que amparou a campanha contra a mostra. Por fim, trago a discussão para a seara da sociologia processual, buscando explicar quais os processos e figurações que possibilitaram sua ocorrência

A prominence eruption from the Sun to the Parker Solar Probe with multi-spacecraft observations

In the early hours of 2021 April 25, the Solar Probe Cup on board Parker Solar Probe registered the passage of a solar wind structure characterized by a clear and constant He2+/H+ density ratio above 6% during three hours. The He2+ contribution remained present but fainting and intermittent within a twelve-hour window. Solar Orbiter and Parker Solar Probe were in nearly perfect quadrature, allowing for optimal observing configuration in which the material impacting the Parker Solar Probe was in the Solar Orbiter plane of the sky and visible off the limb. In this work, we report the journey of the helium-enriched plasma structure from the Sun to the Parker Solar Probe by combining multi-spacecraft remote-sensing and in situ measurements. We identify an erupting prominence as the likely source, behind the Sun relative to the Earth, but visible to multiple instruments on both the Solar-Terrestrial Relations Observatory-A and Solar Orbiter. The associated CME was also observed by coronagraphs and heliospheric imagers from both spacecrafts before reaching the Parker Solar Probe at 46 R⊙, 8 h after the spacecraft registered a crossing of the heliospheric current sheet. Except for extraordinary helium enhancement, the CME showed ordinary plasma signatures and a complex magnetic field with an overall strength enhancement. The images from the Wide-field Imager for Solar Probe (WISPR) aboard Parker Solar Probe show a structure entering the field of view a few hours before the in situ crossing, followed by repetitive transient structures that may be the result of flying through the CME body. We believe this to be the first example of a CME being imaged by WISPR directly before and during being detected in situ. This study highlights the potential of combining the Parker Solar Probe in situ measurements in the inner heliosphere with simultaneous remote-sensing observations in (near) quadrature from other spacecrafts

Potential of Core-Collapse Supernova Neutrino Detection at JUNO

JUNO is an underground neutrino observatory under construction in Jiangmen, China. It uses 20kton liquid scintillator as target, which enables it to detect supernova burst neutrinos of a large statistics for the next galactic core-collapse supernova (CCSN) and also pre-supernova neutrinos from the nearby CCSN progenitors. All flavors of supernova burst neutrinos can be detected by JUNO via several interaction channels, including inverse beta decay, elastic scattering on electron and proton, interactions on C12 nuclei, etc. This retains the possibility for JUNO to reconstruct the energy spectra of supernova burst neutrinos of all flavors. The real time monitoring systems based on FPGA and DAQ are under development in JUNO, which allow prompt alert and trigger-less data acquisition of CCSN events. The alert performances of both monitoring systems have been thoroughly studied using simulations. Moreover, once a CCSN is tagged, the system can give fast characterizations, such as directionality and light curve

Detection of the Diffuse Supernova Neutrino Background with JUNO

As an underground multi-purpose neutrino detector with 20 kton liquid scintillator, Jiangmen Underground Neutrino Observatory (JUNO) is competitive with and complementary to the water-Cherenkov detectors on the search for the diffuse supernova neutrino background (DSNB). Typical supernova models predict 2-4 events per year within the optimal observation window in the JUNO detector. The dominant background is from the neutral-current (NC) interaction of atmospheric neutrinos with 12C nuclei, which surpasses the DSNB by more than one order of magnitude. We evaluated the systematic uncertainty of NC background from the spread of a variety of data-driven models and further developed a method to determine NC background within 15\% with {\it{in}} {\it{situ}} measurements after ten years of running. Besides, the NC-like backgrounds can be effectively suppressed by the intrinsic pulse-shape discrimination (PSD) capabilities of liquid scintillators. In this talk, I will present in detail the improvements on NC background uncertainty evaluation, PSD discriminator development, and finally, the potential of DSNB sensitivity in JUNO

Real-time Monitoring for the Next Core-Collapse Supernova in JUNO

Core-collapse supernova (CCSN) is one of the most energetic astrophysical events in the Universe. The early and prompt detection of neutrinos before (pre-SN) and during the SN burst is a unique opportunity to realize the multi-messenger observation of the CCSN events. In this work, we describe the monitoring concept and present the sensitivity of the system to the pre-SN and SN neutrinos at the Jiangmen Underground Neutrino Observatory (JUNO), which is a 20 kton liquid scintillator detector under construction in South China. The real-time monitoring system is designed with both the prompt monitors on the electronic board and online monitors at the data acquisition stage, in order to ensure both the alert speed and alert coverage of progenitor stars. By assuming a false alert rate of 1 per year, this monitoring system can be sensitive to the pre-SN neutrinos up to the distance of about 1.6 (0.9) kpc and SN neutrinos up to about 370 (360) kpc for a progenitor mass of 30$M_{\odot}$ for the case of normal (inverted) mass ordering. The pointing ability of the CCSN is evaluated by using the accumulated event anisotropy of the inverse beta decay interactions from pre-SN or SN neutrinos, which, along with the early alert, can play important roles for the followup multi-messenger observations of the next Galactic or nearby extragalactic CCSN.Comment: 24 pages, 9 figure

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age  6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score  652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

HORROR, HONOUR AND RIGHTS - SEXUAL VIOLENCE AGAINST CHILDREN IN THE 20TH CENTURY

Nesta tese, traço as principais transformações ocorridas na percepção e sensibilidade sociais a respeito da violência sexual contra crianças e adolescentes ao longo do século XX no Brasil. Em primeiro lugar, apresento a legislação nacional e os principais acordos internacionais (Convenções). Em seguida, discuto o contexto intelectual que reflete a sensibilidade dos diferentes períodos e que, de algum modo, acabou por influenciar as definições legais. Para tanto, analisarei algumas decorrências do positivismo na área médica e jurídica, as discussões em torno da prostituição e da polícia de costumes, sua atuação em conjunto com assistentes sociais e, por fim, a visão das organizações não governamentais e dos psicólogos. No capítulo seguinte, analiso alguns movimentos sociais internacionais ou ofensivas civilizatórias , cujo objetivo era combater a violência sexual, e seus desdobramentos no país. Por fim, resgato o que foi publicado em um jornal de grande circulação, O Estado de S. Paulo, a fim de identificar mudanças nas informações transmitidas ao público leigo (leitores), nos tipos de crimes sexuais noticiados e na abordagem ao tema. O argumento defendido é que a violência sexual contra crianças e adolescentes não era um problema desconhecido do público leigo, tampouco de especialistas como médicos, juristas, policiais e assistentes sociais. Era, entretanto, entendido como um problema esporádico e relacionado a questões morais. Aproximando-se o final do século, nas mãos das organizações não governamentais nacionais e internacionais, a violência sexual passou a ser entendida como um fenômeno", algo recorrente e que deveria ser estudado, quantificado e analisado cientificamente. O que era noticiado casualmente passou a sê-lo recorrentemente, chegando às manchetes dos jornais. A dinâmica que engendrou essas mudanças é encontrada na diminuição da desigualdade na balança de poder entre os sexos e em um aumento na distância social entre adultos e crianças cada vez mais entendidas como pessoas com necessidades específicas e que devem ser protegidas e cuidadas. A abordagem teórica é a sociologia processual de Norbert Elias. A tese contém ainda um excurso referente às transformações no tocante à violência sexual na Irlanda. As diferenças e semelhanças entre as transformações ocorridas na Irlanda e no Brasil são utilizadas para elucidar os processos sociais que levaram o tema da violência sexual ao centro das atenções no último quartel do século XX.In this thesis, I describe the main changes in social sensibility towards child sexual violence in 20th century Brazil. First of all, I present the national law and the main international agreements in regard to sexual violence. Following, I will show some expert discourses that reflect different sensibilities over this topic and that, in some way, influenced legal definitions. In order to make this discussion, the following will be analysed: some influences of positivism in the medical and legal areas; some queries and opinions on prostitution and manners police"; its work along with social workers; and, at last, the understandings of NGOs and psychologists. In the next chapter, I analyse some international social movements also called civilising offensives that intended to combat sexual violence, and its consequences in Brazil. Last, it will be shown what one of the most important daily newspapers in the country has published in this connection. Daily news will be used to discuss changes in the information published, in the kind of sexual crime depicted and how it is discussed. The main argument of this work is that child sexual violence was not an invisible problem to lay people nor to experts as physicians, people working in the legal system, police and social workers. Nevertheless, it was seen as an occasional problem related to morality. Towards the end of the 20th century, especially because of national and international NGOs, sexual violence came to be seen as a very recurrent problem and a topic that should be studied, quantified and scientifically analysed. What was occasionally portrayed in the media became a very common issue, reaching the head-lines. These changes can be explained by the shift in the balance of power between the sexes in favour of women and an increase in the social distance between adults and children, now understood as people with special need that should be protected and cared for. The theoretical approach is Norbert Eliass process sociology. The thesis contains also an excursus, discussing changes in child sexual violence in 20th century Ireland. Differences and similarities between what happened in Ireland and in Brazil will be used to discuss social processes that lead sexual violence to be a topic of great concern in the last quarter of the century
