Histories of hating

This roundtable discussion presents a dialogue between digital culture scholars on the seemingly increased presence of hating and hate speech online. Revolving primarily around the recent #GamerGate campaign of intensely misogynistic discourse aimed at women in video games, the discussion suggests that the current moment for hate online needs to be situated historically. From the perspective of intersecting cultural histories of hate speech, discrimination, and networked communication, we interrogate the ontological specificity of online hating before going on to explore potential responses to the harmful consequences of hateful speech. Finally, a research agenda for furthering the historical understandings of contemporary online hating is suggested in order to address the urgent need for scholarly interventions into the exclusionary cultures of networked media

Patterns of media coverage repeated in online abuse on high-profile criminal cases

What relationship do the mainstream media have with online abuse on high-profile criminal cases? This article hopes to make a start at answering this question by examining tweets containing the #McCann hashtag, utilised by a highly engaged community of users to comment on all matters related to the disappearance of British child Madeleine McCann. On #McCann, the child’s parents and other players are often singled out as the perpetrators of her disappearance and other crimes, in a blend of harassment, defamation and insults with conspiracy theories, disinformation and a strong anti-establishment vein typical of the posttruth era. Through an experimental digital ethnography blending elements of content and discourse analysis, this research has observed the #McCann conversation and analysed 500 tweets with the hashtag, observing that some of the most offensive theories posted by users on Twitter reprised themes seen in the mainstream media at the time of the disappearance, which resulted in defamation lawsuits by the McCanns and in complaints about unethical reporting at the Leveson Inquiry. This raises questions about the mainstream media’s responsibility and duty of care towards people they report on in the digital age, and showcases a symbiotic yet diffident relationship between anti-establishment online users and traditional news media

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum

Towards a research agenda for examining online gender based violence against women academics

Gender based violence in virtual environments is commonly experienced by women and girls, and online abuse has become a significant social problem. High profile women in a variety of professions often become victims of online violence. The topic of online gender-based violence has to date received scant academic attention. Little is known about how female academics are represented and treated in online and social media spaces. Academics are increasingly exhorted to disseminate their work and to engage with an audience outside academia but the online violence against female academics compromises their ability to fulfil this agenda. This paper provides insight into the literature surrounding the experiences of women academics negotiating virtual spaces and further presents a research agenda in order to explore the phenomenon more closely. In doing so, we highlight the need for greater protection and regulation of virtual environments in order to support those who use them

Vertical and horizontal distribution of regional new particle formation events in Madrid

The vertical profile of new particle formation (NPF) events was studied by comparing the aerosol size number distributions measured aloft and at surface level in a suburban environment in Madrid, Spain, using airborne instruments. The horizontal distribution and regional impact of the NPF events was investigated with data from three urban, urban background, and suburban stations in the Madrid metropolitan area. Intensive regional NPF episodes followed by particle growth were simultaneously recorded at three stations in and around Madrid during a field campaign in July 2016. The urban stations presented larger formation rates compared to the suburban station. Condensation and coagulation sinks followed a similar evolution at all stations, with higher values at urban stations. However, the total number concentration of particles larger than 2.5 nm was lower at the urban station and peaked around noon, when black carbon (BC) levels are at a minimum. The vertical soundings demonstrated that ultrafine particles (UFPs) are formed exclusively inside the mixed layer. As convection becomes more effective and the mixed layer grows, UFPs are detected at higher levels. The morning soundings revealed the presence of a residual layer in the upper levels in which aged particles (nucleated and grown on previous days) prevail. The particles in this layer also grow in size, with growth rates significantly smaller than those inside the mixed layer. Under conditions with strong enough convection, the soundings revealed homogeneous number size distributions and growth rates at all altitudes, which follow the same evolution at the other stations considered in this study. This indicates that UFPs are detected quasi-homogenously in an area spanning at least 17 km horizontally. The NPF events extend over the full vertical extension of the mixed layer, which can reach as high as 3000 m in the area, according to previous studies. On some days a marked decline in particle size (shrinkage) was observed in the afternoon, associated with a change in air masses. Additionally, a few nocturnal nucleation-mode bursts were observed at the urban stations, for which further research is needed to elucidate their origin.Peer reviewe

“It’s a terrible way to go to work:” what 70 million readers’ comments on the Guardian revealed about hostility to women and minorities online

In 2006, the Guardian opened many of its articles to readers’ comments to encourage a “conversation” between journalists and their readers. Readers responded enthusiastically, and by 2016 they had posted 70 million comments on the site. However, from the outset many journalists complained about the quality and tone of comments. Female and BAME (Black, Asian and minority ethnic) journalists in particular complained that they were subject to more abuse than their male, white counterparts. This study finds prima facie evidence to support the journalists’ claims. Using comments that had been blocked by moderators as a proxy for abuse and dismissive trolling, it was found that articles written by women did attract a higher percentage of blocked comments than those written by men, regardless of the subject of the article; this effect was heightened when the articles ran in a particularly male-dominated section of the site. There was also evidence that articles written by BAME writers attracted disproportionate levels of blocked comments, even though the research was not designed to reveal this. Preliminary research findings were published in the Guardian and readers were invited to comment on them. Guardian journalists’ experiences of comments were also surveyed. Both sets of responses are analysed here, in order to explore the contested nature of online abuse in an online news media environment, and to evaluate the potential of comments to “democratise” journalism

The BRAIN TRIAL: a randomised, placebo controlled trial of a Bradykinin B2 receptor antagonist (Anatibant) in patients with traumatic brain injury

BACKGROUND: Cerebral oedema is associated with significant neurological damage in patients with traumatic brain injury. Bradykinin is an inflammatory mediator that may contribute to cerebral oedema by increasing the permeability of the blood-brain barrier. We evaluated the safety and effectiveness of the non-peptide bradykinin B2 receptor antagonist Anatibant in the treatment of patients with traumatic brain injury. During the course of the trial, funding was withdrawn by the sponsor. METHODS: Adults with traumatic brain injury and a Glasgow Coma Scale score of 12 or less, who had a CT scan showing an intracranial abnormality consistent with trauma, and were within eight hours of their injury were randomly allocated to low, medium or high dose Anatibant or to placebo. Outcomes were Serious Adverse Events (SAE), mortality 15 days following injury and in-hospital morbidity assessed by the Glasgow Coma Scale (GCS), the Disability Rating Scale (DRS) and a modified version of the Oxford Handicap Scale (HIREOS). RESULTS: 228 patients out of a planned sample size of 400 patients were randomised. The risk of experiencing one or more SAEs was 26.4% (43/163) in the combined Anatibant treated group, compared to 19.3% (11/57) in the placebo group (relative risk = 1.37; 95% CI 0.76 to 2.46). All cause mortality in the Anatibant treated group was 19% and in the placebo group 15.8% (relative risk 1.20, 95% CI 0.61 to 2.36). The mean GCS at discharge was 12.48 in the Anatibant treated group and 13.0 in the placebo group. Mean DRS was 11.18 Anatibant versus 9.73 placebo, and mean HIREOS was 3.94 Anatibant versus 3.54 placebo. The differences between the mean levels for GCS, DRS and HIREOS in the Anatibant and placebo groups, when adjusted for baseline GCS, showed a non-significant trend for worse outcomes in all three measures. CONCLUSION: This trial did not reach the planned sample size of 400 patients and consequently, the study power to detect an increase in the risk of serious adverse events was reduced. This trial provides no reliable evidence of benefit or harm and a larger trial would be needed to establish safety and effectiveness. TRIAL REGISTRATION: This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN23625128
