- This Special Issue of Nordicom Review discusses interactive practices of articulating and communicating uncivility in the context of recent wider anti- and post-democratic change. We consider that change as a cross-national phenomenon that has been taking place in the Nordic countries, Europe, and indeed elsewhere since the late 1990s and early 2000s, and one that has significantly accelerated with the global rise of the “anxious politics” (Albertson & Gadarian, 2015) of right-wing populism and the far-right (Moffitt, 2016; Mudde, 2019) in recent decades. While our collection joins an ongoing and growing body of research on both un- and incivility – which we describe and to some extent disentangle conceptually in detail below – it carries a few pronounced aims which characterise its contribution to the wider research on mediated and political communication in the context of a crisis of liberal democracy and the rise of nativism and far-right populism.

Tidskriftsartikel (refereegranskat)abstract
- The vector-boson production cross section for the Higgs boson decay in the H→WW*→eνμν channel is measured as a function of kinematic observables sensitive to the Higgs boson production and decay properties as well as integrated in a fiducial phase space. The analysis is performed using the proton-proton collision data collected by the ATLAS detector in Run 2 of the LHC at √s=13 TeV center-of-mass energy, corresponding to an integrated luminosity of 139 fb−1. The different flavor final state is studied by selecting an electron and a muon originating from a pair of W bosons and compatible with the Higgs boson decay. The data are corrected for the effects of detector inefficiency and resolution, and the measurements are compared with different state-of-the-art theoretical predictions. The differential cross sections are used to constrain anomalous interactions described by dimension-six operators in an effective field theory.

Luminosity determination in pp collisions at √s=13 TeV using the ATLAS detector at the LHC
- 2023

Tidskriftsartikel (refereegranskat)abstract
- The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented, with pp collisions at a centre-of-mass energy s=13 TeV. The absolute luminosity scale is determined using van der Meer beam separation scans during dedicated running periods in each year, and extrapolated to the physics data-taking regime using complementary measurements from several luminosity-sensitive detectors. The total uncertainties in the integrated luminosity for each individual year of data-taking range from 0.9% to 1.1%, and are partially correlated between years. After standard data-quality selections, the full Run 2 pp data sample corresponds to an integrated luminosity of 140.1 ± 1.2 fb - 1 , i.e. an uncertainty of 0.83%. A dedicated sample of low-pileup data recorded in 2017–2018 for precision Standard Model physics measurements is analysed separately, and has an integrated luminosity of 338.1 ± 3.1 pb - 1 . © 2023, The Author(s).

Measurement of the Sensitivity of Two-Particle Correlations in pp Collisions to the Presence of Hard Scatterings
- 2023
-
Ingår i: Physical Review Letters. - : American Physical Society. - 0031-9007 .- 1079-7114. ; 131:16
-
Tidskriftsartikel (refereegranskat)abstract
- A key open question in the study of multiparticle production in high-energy pp collisions is the relationship between the “ridge”—i.e., the observed azimuthal correlations between particles in the underlying event that extend over all rapidities—and hard or semihard scattering processes. In particular, it is not known whether jets or their soft fragments are correlated with particles in the underlying event. To address this question, two-particle correlations are measured in pp collisions at √s=13 TeV using data collected by the ATLAS experiment at the LHC, with an integrated luminosity of 15.8 pb−1, in two different configurations. In the first case, charged particles associated with jets are excluded from the correlation analysis, while in the second case, correlations are measured between particles within jets and charged particles from the underlying event. Second-order flow coefficients, v2, are presented as a function of event multiplicity and transverse momentum. These measurements show that excluding particles associated with jets does not affect the measured correlations. Moreover, particles associated with jets do not exhibit any significant azimuthal correlations with the underlying event, ruling out hard processes contributing to the ridge.

Tidskriftsartikel (refereegranskat)abstract
- This Letter reports the observation of single top quarks produced together with a photon, which directly probes the electroweak coupling of the top quark. The analysis uses 139 fb−1 of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. Requiring a photon with transverse momentum larger than 20 GeV and within the detector acceptance, the fiducial cross section is measured to be 688±23(stat) , to be compared with the standard model prediction of at next-to-leading order in QCD.

A populist turn? News editorials and the recent discursive shift on immigration in Sweden
- 2021
-
Ingår i: Nordicom Review. - : Walter de Gruyter GmbH. - 1403-1108 .- 2001-5119. ; 42:1, s. 67-87
-
Tidskriftsartikel (refereegranskat)abstract
- This article undertakes a critical discourse analysis of Swedish quality newspaper editorials and their evolving framing of immigration since the 2015 peak of the recent European “refugee crisis”. Positioned within the ongoing discursive shifts in the Swedish public sphere and the growth of discursive uncivility in its mainstream areas, the analysis highlights how xenophobic and racist discourses once propagated by the far and radical right gradually penetrate into the studied broadsheet newspapers. We argue that the examined editorials carry the tendency to normalise once radical perceptions of immigration. This takes place by incorporating various discursive strategies embedded in wider argumentative frames – or topoi – of demographic consequences, Islam and Islamisation, threat, and integration. All of these enable constructing claims against immigration now apparently prevalent in the examined strands of the Swedish “quality” press.

Media criticism as a propaganda strategy in political communication
- 2023
-
Ingår i: Nordic Journal of Media Studies. - 2003-184X. ; 5:1, s. 115-133
-
Tidskriftsartikel (refereegranskat)abstract
- Over the last decade, strategic attacks on news media institutions and journalists have become an increasingly common feature of populist political communication. The purpose of this article is to identify various strategies that politicians use to criticise the news media and illuminate how the use and circulation of these strategies vary between party types. The article builds on a content analysis of the Twitter feeds of all members of parliament with an active account during the 2018 Swedish election campaign. Results show that political media criticism in Sweden is strongly associated with political personalisation, and it is almost exclusively a right-wing phenomenon, though not restricted specifically to populist parties. Public service media rather than newspapers or commercial broadcasters constitute the prime target for political media criticism in Sweden, illustrating the need to take media systemic aspects in to account when analysing media criticism as a propaganda strategy in political communication.

Parasitic news : Adoption and adaption of journalistic conventions in hybrid political communication
- 2024

Tidskriftsartikel (refereegranskat)abstract
- This article explores how political parties and individual politicians in Sweden communicate strategically in an online environment where the close relationship between news and journalistic institutions no longer can be taken for granted. We define the adoption and adaption of journalistic conventions in political communication as a particular communication style, conceptualized as “parasitic news”. The article presents an analytical framework that explicates the role of parasitic news across five dimensions: ideological transparency/position, alternativeness, news genres, individual vs. collective media practices, and social media affordances. An analysis of three news projects, representing right-wing populist, liberal/conservative, and left-wing/green ideological positions, reveals that parasitic news is a flexible communication style that blurs the boundaries of politics and media in online spaces. Moreover, parasitic news challenges the relevance of established terms such as alternative, hyper-partisan, and fake news, pointing to the need of a renewed conceptual vocabulary in journalism, media and political communication research.
