Information security and journalism: mapping a nascent research field

Information security (infosec) has become a field of primary interest for journalism, especially in the wake of the 2013 Edward Snowden revelations about the ramifications of Internet mass surveillance. Following the increasing dangers posed by digital threats—and surveillance in particular—to the safety of journalists and their sources, newsrooms and reporters have shown an increased interest in technological solutions for improved protection of their work and sources. In particular, the adoption of strong encryption tools for communication purposes has become an urgent matter for journalists worldwide, becoming a niche of research in journalism studies as well. By reviewing the existing literature in the field, this article examines how journalism studies approach the use of encryption and information security tools for journalistic purposes. Based on research on the major journalism studies journals and other publications, the article offers an overview of the research advancements, highlighting current major trends and research areas

Weak systems unveiling the vulnerabilities of digitization

This article discusses digitization weaknesses, biases, and malfunctions to challenge popular, almost hegemonic visions of contemporary technologies. By focusing on examples provided by recent mediated cases, controversies, and critical research about biases, we aim to propose an analysis of anything digital starting from its vulnerabilities, to look beyond polarized deterministic views, both optimistic and pessimistic. The article generates from the thematic track: "Weak Systems. Exploring bias, bugs and the vulnerability of digitization" that took place at the VIII STS Italia Conference. The panel brought together scholars from different backgrounds, including STS, history of technology, sociology of communication and critical data and media studies to discuss instances of technological weaknesses in various contexts. The article sums up some of the panel takeaways and pleas for a cooperative and interdisciplinary effort focusing on "weak systems"

El estado de “Europeanización”: Entre conflicto y convergencia. Una comparación de cobertura de las Elecciones Europeas 2019 en siete países

The issue of the Europeanisation of national public spheres is a question as to how a discursive media space can be created within the EU. There are forces of convergence at work, such as networking within the borderless digital space. At the same time, there are counterforces: increasing nationalism and populists who identify ‘Brussels’ as a target for their criticism of elites. The vision of a European public sphere appears to share the same fate as the European project as such; as a result of years of crisis, optimism has given way to disillusion. Using coverage of the 2019 EU elections in seven European countries (a total of 57,943 articles from Germany, Hungary, Italy, Poland, Portugal, the Czech Republic, and the UK), we draw a picture of a heterogeneous EU public. What is particularly clear is that the phenomena of horizontal and vertical Europeanisation require more nuanced interpretations. While a high degree of horizontal Europeanisation indicates convergent and pro-European media coverage (as in the cases of Germany and Portugal), a high degree of vertical Europeanisation may indicate polarised publics or an unfree media landscape (as in the UK and Hungary). From a methodological point of view, the study shows that a combination of computational content analysis and international cooperation between scientists can advance research into the European public.La “europeización” de las esferas públicas nacionales es una cuestión de crear un espacio mediático discursivo dentro de la UE. Hay fuerzas de convergencia, como redes en el espacio digital. Al mismo tiempo, hay fuerzas contrarias, un creciente nacionalismo y populistas que critican las élites a “Bruselas”. Aparentemente, la visión de una esfera pública europea comparte su suerte con el proyecto Europeo: después de años de crisis, el optimismo se convirtió en desilusión. Utilizando la cobertura mediática de las elecciones de la UE de 2019 en siete países europeos (57.943 artículos de Alemania, Hungría, Italia, Polonia, Portugal, la República Checa y el Reino Unido), dibujamos cuadro de un público heterogéneo de la UE. Resulta claramente que la europeización horizontal y vertical requieren interpretaciones diferenciadas. Un alto grado de europeización horizontal indica una cobertura mediática convergente y pro-europea (como Alemania o Portugal), un alto grado vertical puede indicar un público polarizado o un panorama mediático poco libre (como el Reino Unido o Hungría)

Hypertension in children and adolescents A consensus document from ESC Council on Hypertension, European Association of Preventive Cardiology, European Association of Cardiovascular Imaging, Association of Cardiovascular Nursing & Allied Professions, ESC Council for Cardiology Practice and Association for European Paediatric and Congenital Cardiology

Definition and management of arterial hypertension in children and adolescents are uncertain, due to different positions of current guidelines. The European Society of Cardiology task-force, constituted by Associations and Councils with interest in arterial hypertension, has reviewed current literature and evidence, to produce a Consensus Document focused on aspects of hypertension in the age range of 6-16 years, including definition, methods of measurement of blood pressure, clinical evaluation, assessment of hypertension-mediated target organ damage, evaluation of possible vascular, renal and hormonal causes, assessment and management of concomitant risk factors with specific attention for obesity, and anti-hypertensive strategies, especially focused on life-style modifications. The Consensus Panel also suggests aspects that should be studied with high priority, including generation of multi-ethnic sex, age and height specific European normative tables, implementation of randomized clinical trials on different diagnostic and therapeutic aspects, and long-Term cohort studies to link with adult cardiovascular risk. Finally, suggestions for the successful implementation of the contents of the present Consensus document are also given

First detection of X-ray polarization from the accreting neutron star 4U 1820-303

This paper reports the first detection of polarization in the X-rays for atoll-source 4U 1820-303, obtained with the Imaging X-ray Polarimetry Explorer (IXPE) at 99.999% confidence level (CL). Simultaneous polarimetric measurements were also performed in the radio with the Australia Telescope Compact Array (ATCA). The IXPE observations of 4U 1820-303 were coordinated with Swift-XRT, NICER, and NuSTAR aiming to obtain an accurate X-ray spectral model covering a broad energy interval. The source shows a significant polarization above 4 keV, with a polarization degree of 2.0(0.5)% and a polarization angle of -55(7) deg in the 4-7 keV energy range, and a polarization degree of 10(2)% and a polarization angle of -67(7) deg in the 7-8 keV energy bin. This polarization also shows a clear energy trend with polarization degree increasing with energy and a hint for a position-angle change of about 90 deg at 96% CL around 4 keV. The spectro-polarimetric fit indicates that the accretion disk is polarized orthogonally to the hard spectral component, which is presumably produced in the boundary/spreading layer. We do not detect linear polarization from the radio counterpart, with a 99.97% upper limit of 50% at 7.25 GHz

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
