Undercurrents: The Oversight Board's Trump decision, and Merkel's legacy Audio bhorton.drupal 25 June 2021

Was Facebook right to suspend Trump? And how will Merkel be remembered?

In the wake of the storming of Capitol Hill on 6 January 2021, social media platforms took steps to remove former President Donald Trump from their websites for infringing community standards. This step was welcomed by many, but also raised serious questions about the power of social media companies to limit free speech and censor elected officials. The suspension of President Trump from Facebook was referred to the Oversight Board, an independent body of experts set up to scrutinise the platform’s content moderation decisions.  

In this episode, Ben speaks to Thomas Hughes and Kate Jones about the outcome of the Oversight Board’s inquiry into the Trump suspension, and the wider implications for content moderation on social media.  

Then Lara is joined by Hans Kundnani to assess the political outlook in Germany and reflect on the legacy of outgoing Chancellor Angela Merkel.  

New UK bill can fight fresh wave of online racist abuse Expert comment NCapeling 21 July 2021

The Euros final and Grand Prix put online abuse once more in the spotlight. The UK’s Online Safety Bill provides a strong framework for tackling the problem.

The ugly online abuse targeted at members of the England football team following the Euros final, and then at Lewis Hamilton after the British Grand Prix, was not only hateful to the individuals concerned, but divisive for the UK more broadly.

More needs to be done to regulate online platforms to avoid the spread of such abuse at scale. Online platforms are making increasing efforts to ‘self-regulate’ in order to tackle online abuse. Over the past year, Facebook and Twitter have strengthened their policies on hateful speech and conduct, such as Facebook’s policy banning Holocaust denial. Both have become more vigilant at deplatforming those who violate their terms of service, such as Donald Trump, and at removing online abuse using a combination of machines and humans.

Twitter announced in the 24 hours following the Euros final that it had removed more than 1,000 tweets, and permanently suspended several accounts, for violating its rules. But inevitably not all abusive posts are picked up given the scale of the issue and, once the post has been seen, arguably the damage is done.

Platforms have also partnered with NGOs on initiatives to counter hate speech and have launched initiatives to tackle the rise in coordinated inauthentic behaviour and information operations that seek to sow distrust and division. But while these efforts are all laudable, they are not enough.

The root of the problem is not the content but a business model in which platforms’ revenue from advertising is directly linked to engagement. This encourages the use of ‘recommender’ algorithms which amplify divisive content by microtargeting users based on previous behaviour, as seen not just with racist abuse but also other toxic content such as anti-vaccination campaigns. Abusers can also remain anonymous, giving them protection from consequences.

Creating a legal duty of care

The UK government’s Online Safety Bill, published in May 2021, aims to tackle harmful content online by placing a duty of care on online platforms to keep users safe and imposing obligations tailored to the size, functionality, and features of the service.

Social media companies will be expected to comply with their duties by carrying out risk assessments for specified categories of harm, guided by codes of practice published by the independent regulator, OFCOM. The bill gives OFCOM the power to fine platforms up to £18 million or ten per cent of global turnover, whichever is higher, for failure to comply.

Following the Euros final, the UK government spoke of referring some racist messages and conduct online to the police. But only a small proportion of it can be prosecuted given the scale of the abuse and the fact only a minority constitutes criminal activity. The majority is ‘lawful but harmful’ content – toxic and dangerous but not technically falling foul of any law.

When addressing ‘lawful but harmful’ material, it is crucial that regulation negotiates the tension between tackling the abuse and preserving freedom of expression. The scale at which such expression can spread online is key here – freedom of speech should not automatically mean freedom of reach. But it is equally important that regulation does not have a chilling effect on free speech, as with the creeping digital authoritarianism in much of the world.

The Online Safety Bill’s co-regulatory approach aims to address these tensions by requiring platforms within the scope of the bill to specify in their terms and conditions how they deal with content on their services that is legal but harmful to adults, and by giving the regulator powers to police how platforms enforce them. Platforms such as Facebook and Twitter may already have strong policies on hate speech – now there will be a regulator to hold them to account.

Devil is in the detail

How successful OFCOM is in doing so will depend on the precise powers bestowed on it in the bill, and how OFCOM chooses to use them. It’s still early days - the bill will be scrutinized this autumn by a committee of MPs before being introduced to parliament. This committee stage will provide an opportunity for consideration of how the bill may need to evolve to get to grips with online abuse.

These latest two divisive and toxic episodes in UK sport are only likely to increase pressure from the public, parliament, and politicians for the bill to reserve robust powers for OFCOM in this area. If companies do not improve at dealing with online abuse, then OFCOM should have the power to force platforms to take more robust action, including by conducting an audit of platforms’ algorithms, enabling it to establish the extent to which their ‘recommender’ settings play a part in spreading hateful content.

Currently, the bill’s definition of harm is confined to harm to individuals, and the government has stated it does not intend this bill to tackle harm to society more broadly. But if racist abuse of individuals provokes racist attacks more widely, as has happened, the regulator should be able to take that wider context into account in its investigation and response.

Responses to the draft bill so far indicate challenges ahead. Some argue the bill does not go far enough to tackle online abuse, especially on the issue of users’ anonymity, while others fear the bill goes too far in stifling freedom of expression, labelling it a recipe for censorship.

Parliamentary scrutiny will need to take into account issues of identity, trust, and authenticity in social networks. While some call for a ban on the cloak of anonymity behind which racist abusers can hide online, anonymity does have benefits for those in vulnerable groups trying to expose hate.

An alternative approach gaining attention is each citizen being designated a secure digital identity, which would both provide users with greater control over what they can see online and enable social media platforms to verify specific accounts. Instituted with appropriate privacy and security safeguards, a secure digital ID would have benefits beyond social media, particularly in an online COVID-19 era.

The online public square is global so countries other than the UK and international organizations must also take measures. It is encouraging to see synergies between the UK’s Online Safety Bill and the EU’s Digital Services Act, published in draft form in December 2020, which also adopts a risk-based, co-regulatory approach to tackling harmful online content. And the UK is using its G7 presidency to work with allies to forge a more coherent response to internet regulation at the international level, at least among democratic states.

Addressing the scourge of online hate speech is challenging so the UK’s Online Safety Bill will not satisfy everyone. But it can give the public, parliament, and politicians a structure to debate these crucial issues and, ultimately, achieve more effective ways of tackling them.

Intact glycopeptide identification has long been known as a key and challenging barrier to the comprehensive and accurate understanding the role of glycosylation in an organism. Intact glycopeptide analysis is a blossoming field that has received increasing attention in recent years. Mass spectrometry (MS)-based strategies and relative software tools are major drivers that have greatly facilitated the analysis of intact glycopeptides, particularly intact N-glycopeptides. This manuscript provides a systematic review of the intact glycopeptide identification process using mass spectrometry data generated in shotgun proteomic experiments, which typically focus on N-glycopeptide analysis. Particular attention is paid to the software tools that have been recently developed in the last decade for the interpretation and quality control of glycopeptide spectra acquired using different MS strategies. The review also provides information about the characteristics and applications of these software tools, discusses their advantages and disadvantages, and concludes with a discussion of outstanding tools.

The increasing consumption of high-fat foods combined with a lack of exercise is a major contributor to the burden of obesity in humans. Aerobic exercise such as running is known to provide metabolic benefits, but how the over-consumption of a high fat diet (HFD) and exercise interact is not well characterized at the molecular level. Here, we examined the plasma proteome in mice for the effects of aerobic exercise as both a treatment and as a preventative regime for animals on either HFD or a healthy control diet. This analysis detected large changes in the plasma proteome induced by the HFD, such as increased abundance of SERPINA7, ALDOB, and down-regulation of SERPINA1E, CFD (adipsin). Some of these changes were significantly reverted using exercise as a preventative measure, but not as a treatment regime. To determine if either the intensity, or duration, of exercise influenced the outcome, we compared high-intensity interval training (HIIT) and endurance running. Endurance running slightly out-performed HIIT exercise, but overall, both provided similar reversion in abundance of plasma proteins modulated by the high-fat diet including SERPINA7, APOE, SERPINA1E, and CFD. Finally, we compared the changes induced by over-consumption of HFD to previous data from mice fed an isocaloric high saturated fat (SFA) or polyunsaturated fat (PUFA) diet. This identified several common changes including increased APOC2 and APOE, but also highlighted changes specific for either over-consumption of HFD (ALDOB, SERPINA7, CFD), SFA-based diets (SERPINA1E), or PUFA-based diets (Haptoglobin - Hp). Together, these data highlight the importance of early intervention with exercise to revert HFD-induced phenotypes and suggest some of the molecular mechanisms leading to the changes in the plasma proteome generated by high fat diet consumption. Web-based interactive visualizations are provided for this dataset (larancelab.com/hfd-exercise), which give insight into diet and exercise phenotypic interactions on the plasma proteome.

Exploring Transatlantic Responses to Far-right Populism in Europe: Simulation Exercise Research paper sysadmin 1 May 2018

A new paper summarizes the findings of a recent simulation exercise exploring how governments on both sides of the Atlantic might respond to a descent towards populist authoritarianism in an EU member state.

Summary

• To better understand how governments on both sides of the Atlantic might respond to a descent towards populist authoritarianism in an EU member state, Chatham House organized a simulation event involving a group of experts drawn from the public sector, academia and NGOs.
• Simulation exercises enable the testing and modelling of the responses of different actors when presented with specific situations; participants’ interactions in a given set of circumstances are explored, and patterns of negotiation are captured and analysed.
• In this simulation, European, US and multilateral representatives were given the task of managing relations with Baltia, a fictional Eastern European state on the verge of electing a far-right nationalist, Eurosceptic government. They were then challenged to manage their relationship with Baltia after it had elected such a government, which was pushing for a ‘leave’ vote in a planned referendum on the country’s continued EU membership.
• The simulation highlighted a number of issues:
  • Limited instruments are available to liberal democratic governments where there is cause for concern regarding the outcome of an election in an allied country. There are relatively few tools at the disposal of governments to support political allies, or to prevent outcomes that are perceived as threatening democratic norms. The simulation reinforced the view that interventionist moves, either from the European Commission or from individual national governments, would be more likely to come in response to an unfavourable development rather than pre-emptively.
  • The EU, and caucuses of European states, are the main international interlocutors in this type of political crisis involving an EU member state. The US opted to play a limited role in the negotiations; the same was largely true for NATO, aside from its action in sharing intelligence about a potential coup in Baltia. France and Germany formed a natural working partnership, taking meetings together and coordinating policies first before discussing them with a wider European circle, although their positions did not always align.
  • The UK’s capacity to shape the outcome of collective EU discussions appeared more restricted, while Brexit also seemed to shape the response of other EU states to the developing situation in Baltia. Although member states were undoubtedly reluctant to see another country go down this route, they were also resolute in demonstrating a unity of approach and limited flexibility in the face of the new populist government’s attempt to divide them.

In nucleotide excision repair, bulky DNA lesions such as UV-induced cyclobutane pyrimidine dimers are removed from the genome by concerted dual incisions bracketing the lesion, followed by gap filling and ligation. So far, two dual-incision patterns have been discovered: the prokaryotic type, which removes the damage in 11–13-nucleotide-long oligomers, and the eukaryotic type, which removes the damage in 24–32-nucleotide-long oligomers. However, a recent study reported that the UvrC protein of Mycobacterium tuberculosis removes damage in a manner analogous to yeast and humans in a 25-mer oligonucleotide arising from incisions at 15 nt from the 3´ end and 9 nt from the 5´ end flanking the damage. To test this model, we used the in vivo excision assay and the excision repair sequencing genome-wide repair mapping method developed in our laboratory to determine the repair pattern and genome-wide repair map of Mycobacterium smegmatis. We find that M. smegmatis, which possesses homologs of the Escherichia coli uvrA, uvrB, and uvrC genes, removes cyclobutane pyrimidine dimers from the genome in a manner identical to the prokaryotic pattern by incising 7 nt 5´ and 3 or 4 nt 3´ to the photoproduct, and performs transcription-coupled repair in a manner similar to E. coli.

Hope, Peace and Reconciliation: Pope Francis in Mozambique Expert comment sysadmin 4 September 2019

A papal visit will highlight the importance of the recently signed peace agreement between the government and opposition.

Pope Francis’ visit to Mozambique on 4–6 September comes at a critical political moment. The theme for the papal Africa trip (which also includes Madagascar and Mauritius) is ‘pilgrim of hope, peace and reconciliation’. This is especially relevant for Mozambique, as this is the first week of the official campaign for Mozambique’s sixth national elections on 15 October.

It is also the one-month anniversary of the Maputo Accords for Peace and Reconciliation between the government and the armed opposition, RENAMO (and the fifth anniversary of the previous such agreement in 2014).

What is unusual is that the pope accepted to visit Mozambique just after a peace accord and in the run-up to national elections. Something similar has happened only once, when Pope John Paul II visited Angola in June 1992 (following the Bicesse Accords) prior to the country’s first ever national elections in September. Unfortunately Pope John Paul’s preaching of reconciliation and pluralism failed and civil war resumed some months later, following rejection of the preliminary election results. Angola’s civil war only finally ended a decade later in 2002.

The last papal visit to Mozambique was also by Pope John Paul II in 1988, when civil war was still ongoing, and the country was still a single party state. Despite the war, massive congregations attended and RENAMO reached local ceasefires and agreements to maintain electricity supply to honour the visit. Some of the seeds for the Rome peace process were laid during this trip – especially as it also represented a formal reconciliation of FRELIMO, the ruling party, with the Catholic Church.

This papal visit to Mozambique is equally anticipated, as was highlighted several times during speeches at the 6 August peace agreement signing in Maputo. When I was in Maputo last month, sales of papal-pictured capulanas (a Mozambican sarong) were brisk and Mozambican television carried countdown clocks on many programmes for the touchdown of Pope Francis on national soil.

The Catholic Church has played an instrumental role in promoting peace in Mozambique over the years. The 1977–92 civil war ended through negotiations hosted at the Sant’ Egidio lay community in Rome, and the current Archbishop of Bologna, Dom Matteo Zuppi (who led the Sant’ Egido negotiations in 1992 and is soon to be made a cardinal) was an official witness to 6 August accords signing.

When targeted armed conflict resumed in 2013, faith groups once more re-engaged and in 2016 Sant’ Egidio once more co-led mediation efforts, less successfully than in 1991–92. Sant’ Egidio (including during a presidential visit to Rome in July) contributed to convincing the Vatican that this papal visit should occur before the October elections.

President Filipe Nyusi anxiously wanted this visit to occur before the elections. He is seeking re-election for his second and final term and a papal visit should help win some votes. His party, FRELIMO, is also worried about securing a majority in the national assembly, as it has been weakened by patchy delivery of services and ongoing high-level corruption scandals.

This year, President Nyusi’s priorities have been to show that he can attract international investment (such as Andarko’s recently announced final investment decision on its gas project), a peace agreement with RENAMO (the August agreements) and a papal visit, so a successful trip would complete his goals.

The pope’s ‘hope, peace and reconciliation’ message of his visit is important. Twice previously, the FRELIMO-led government and RENAMO have reached definitive agreements, in Rome (1992) and Maputo (2014), but failed to fully end bloodshed. This new August 2019 agreement is the third attempt, and if it is to last, it will require political goodwill, compromise and an acceptance of more inclusive national politics by both parties.

There are two immediate threats to this agreement. The first is the forthcoming 15 October elections and their conduct could make or break it. Accepting reconciliation and greater pluralism underpins this agreement, but RENAMO expects to increase its share of the parliamentary vote and win a majority in some provinces (and therefore indirectly elect their choice for governor).

A second threat is the ‘Military Junta’, a RENAMO splinter group that claims to be 500 strong, but probably accounts for 80 armed persons. It rejects the 6 August agreement and warns that it could disrupt the elections. This group has asked for mediation, and hopefully can be accommodated in a side deal to the main one agreed in August, which already provides for the reintegration of over 5,000 RENAMO supporters and combatants.

A recent Chatham House research paper on elite bargains in Mozambique concluded that the October elections will be the first immediate test of the August agreement. If the elections pass without significant electoral manipulation or violence and this August deal sticks on the third attempt, the domestic focus should then move onto poverty reduction, combating inequality, education and solving the new security crisis with Islamic militants in Cabo Delgado province.

Neural responses are naturally variable from one moment to the next, even when the stimulus is held constant. What factors might underlie this variability in neural population activity? We hypothesized that spontaneous fluctuations in cortical stimulus representations are created by changes in arousal state. We tested the hypothesis using a combination of fMRI, probabilistic decoding methods, and pupillometry. Human participants (20 female, 12 male) were presented with gratings of random orientation. Shortly after viewing the grating, participants reported its orientation and gave their level of confidence in this judgment. Using a probabilistic fMRI decoding technique, we quantified the precision of the stimulus representation in the visual cortex on a trial-by-trial basis. Pupil size was recorded and analyzed to index the observer's arousal state. We found that the precision of the cortical stimulus representation, reported confidence, and variability in the behavioral orientation judgments varied from trial to trial. Interestingly, these trial-by-trial changes in cortical and behavioral precision and confidence were linked to pupil size and its temporal rate of change. Specifically, when the cortical stimulus representation was more precise, the pupil dilated more strongly prior to stimulus onset and remained larger during stimulus presentation. Similarly, stronger pupil dilation during stimulus presentation was associated with higher levels of subjective confidence, a secondary measure of sensory precision, as well as improved behavioral performance. Taken together, our findings support the hypothesis that spontaneous fluctuations in arousal state modulate the fidelity of the stimulus representation in the human visual cortex, with clear consequences for behavior.

Key event-related potentials (ERPs) of perceptual decision-making such as centroparietal positivity (CPP) elucidate how evidence is accumulated toward a given choice. Furthermore, this accumulation can be impacted by visual target selection signals such as the N2 contralateral (N2c). How these underlying neural mechanisms of perceptual decision-making are influenced by the spatial congruence of distractors relative to target stimuli remains unclear. Here, we used electroencephalography (EEG) in humans of both sexes to investigate the effect of distractor spatial congruency (same vs different hemifield relative to targets) on perceptual decision-making. We confirmed that responses for perceptual decisions were slower for spatially incongruent versus congruent distractors of high salience. Similarly, markers of target selection (N2c peak amplitude) and evidence accumulation (CPP slope) were found to be lower when distractors were spatially incongruent versus congruent. To evaluate the effects of congruency further, we applied drift diffusion modeling to participant responses, which showed that larger amplitudes of both ERPs were correlated with shorter nondecision times when considering the effect of congruency. The modeling also suggested that congruency's effect on behavior occurred prior to and during evidence accumulation when considering the effects of the N2c peak and CPP slope. These findings point to spatially incongruent distractors, relative to congruent distractors, influencing decisions as early as the initial sensory processing phase and then continuing to exert an effect as evidence is accumulated throughout the decision-making process. Overall, our findings highlight how key electrophysiological signals of perceptual decision-making are influenced by the spatial congruence of target and distractor.
