Anonymity and Democracy: Absence as Presence in the Public Sphere

Although anonymity is a central feature of liberal democracies—not only in the secret ballot, but also in campaign funding, publishing political texts, masked protests, and graffiti—it has so far not been conceptually grounded in democratic theory. Rather, it is treated as a self-explanatory concept related to privacy. To overcome this omission, this article develops a complex understanding of anonymity in the context of democratic theory. Drawing upon the diverse literature on anonymity in political participation, it explains anonymity as a highly context-dependent identity performance expressing private sentiments in the public sphere. The contradictory character of its core elements—identity negation and identity creation—results in three sets of contradictory freedoms. Anonymity affords (a) inclusion and exclusion, (b) subversion and submission, and (c) honesty and deception. This contradictory character of anonymity’s affordances illustrates the ambiguous role of anonymity in democracy

Making a Difference: Toward a Feminist Democratic Theory in the Digital Age

This essay asks how the democratic ideal of inclusion can be achieved in societies marked by pow-er asymmetries along the lines of identity categories such as gender and race. It revisits debates of difference democracy of the 1990's, which promoted inclusion through a politics of presence of marginalized social groups. This strategy inevitably entails essentializing tendencies, confining the democratic subject within its physically embodied identity. Difference democrats did not take notice of the parallel emerging discourse on cyberfeminism exploring novel identity configurations on the internet. This essay augments the politics of presence with digital identity reconfigurations. Neither difference democrats nor cyberfeminists distinguished between various participatory sites. Drawing on conceptions of participatory spaces from development studies and deliberative democracy, this essay generates a typology differentiating between empowered spaces such as parliaments, invited spaces such as citizens' assemblies, and claimed spaces of social movements. The democratic func-tions these spaces fulfil are best facilitated by three different modes of identity performance: identity continuation, identity negation, and identity exploration. A pluralization of participatory sites and modes of identity performance facilitates inclusion while tackling the essentializing tendencies in difference democracy

Subject to Change: Democracy, Disidentification, and the Digital

Radical democratic politics in the digital age is characterized by the widespread emergence of participatory spaces generated by state actors and social movements. These new formats of citizen engagement are situated in the context of social inequalities and discrimination of marginalized identities. To counter this problem, feminist debates in democratic theory associated with the term “difference democracy” advocate a politics of presence through physically embodied representation of marginalized groups, providing visibility in the space of appearance. This strategy, however, entails essentializing tendencies as subjects are judged by their physical appearance rather than the content they utter, a problem described as the “dilemma of difference”. This thesis seeks ways out of the dilemma of difference by advancing both freedom and equality in participatory spaces. It explores the relations of freedom and equality that are described as competing values in the democratic paradox. To make the freedom to explore the multiple self compatible with the equality facilitated through the presence of the marginalized, the thesis engages with a range of radical democratic perspectives. To the established participatory, deliberative, and agonistic approaches it adds feminist and transformative perspectives. On these grounds, it develops the concept of a politics of becoming, which is seen as part of a progressive strategy of systemic transformation. Inspired by queer and gender theory, the politics of becoming reinterprets presence as the performative act of self-constitution. To enlarge the free spaces of the subject to change, the thesis suggests radical democratic practices of disidentification through anonymity that affords the opportunity to reject hegemonic identity interpellations and contributes to a democratization of self-constitution. Drawing on new materialist thought allows for an interpretation of both spatial configurations and the subject as agentic assemblages. Anonymity and other modes of disidentification enable an interruption of such assemblages and reassemble spaces and the self. Digital means of communication provide new affordances for identity expressions. The emerging cyborgian subjects reassemble identity and reconfigure the space of appearance. This results in a new politics of presence that expresses embodied difference but still provides freedom for the subject to change

Revisiting E-topia: Theoretical Approaches and Empirical Findings on Online Anonymity

As social hierarchies along identity markers of gender, race, age etc. are replicated within participatory spaces, the question arises as to how online participation and its modes of identity reconfiguration might affect this dilemma. This paper first revisits the discussions about cyberdemocracy in the 1990s, which focused on the liberating effects of anonymity facilitating an inclusive sphere of equals. It then moves on to the arguments of cyberfeminist debates, criticizing the naivety of cyberdemocracy by pointing to the persistence of offline inequalities in cyberspace. Current discussions pick up this criticism and focus on visual re-embodiment and the persistence of identity online. After giving an overview of these theoretical debates, the paper turns to empirical findings on the effects of online anonymity. Various studies from different disciplines show that anonymity has both democratic and anti-democratic effects. It both liberates the democratic subjects and at the same time contributes to new modes of domination. Thus, the theoretical accounts of optimistic cyberdemocrats and pessimistic cyberfeminists together contribute to a holistic understanding of online anonymity in participatory spaces

Master Equation for the Motion of a Polarizable Particle in a Multimode Cavity

We derive a master equation for the motion of a polarizable particle weakly interacting with one or several strongly pumped cavity modes. We focus here on massive particles with complex internal structure such as large molecules and clusters, for which we assume a linear scalar polarizability mediating the particle-light interaction. The predicted friction and diffusion coefficients are in good agreement with former semiclassical calculations for atoms and small molecules in weakly pumped cavities, while the current rigorous quantum treatment and numerical assessment sheds a light on the feasibility of experiments that aim at optically manipulating beams of massive molecules with multimode cavities.Comment: 30 pages, 5 figure

The masked demos: Associational anonymity and democratic practice

The increased use of anonymous digital platforms raises substantive concerns about accountability in digital spaces. However, contemporary evaluations of anonymity focus too narrowly on its protective function: its ability to protect a diversity of speakers and ideas. Drawing on two examples of anonymous political engagements – Publius’s writing of the Federalist Papers and college students’ use of the social media platform Yik Yak – we develop an account of anonymity’s associational function: the processes by which people generate and negotiate collective identities, discussions, and actions in wider publics. As we argue, anonymity’s associational function can (1) generate conditions under which individuals develop collective interests and identities to foster collective action, and (2) enable novel interactions between these individuals and communities and the larger publics of which they are part. We conclude with a discussion of how attention to associational anonymity can contribute to a more nuanced account of democracy in practice

Cyborg Activism: Exploring the reconfigurations of democratic subjectivity in Anonymous

This article develops the concept of cyborg activism as novel configuration of democratic subjectivity in the Information Age by exploring the online collectivity Anonymous as a prototype. By fusing elements of human/machine and organic/digital the cyborg disrupts modern logics of binary thinking. Cyborg activism emerges as the reconfiguration of equality/hierarchy, reason/emotion, and nihilism/idealism. Anonymous demonstrates how through the use of contingent and ephemeral digital personae hierarchies in cyborg activism prove more volatile than in face-to-face settings. Emotions appear as an essential part of a politics of passion, which enables pursuing laughter and joy, expressing anger, and experiencing empowerment as part of a reasoned, strategic politics. Anonymous’ political content reconfigures nihilist sentiments, frustration, and political disenchantment on the one hand with idealist world views on the other. This enables the cohabitation and partial integration of a great diversity of political claims rooted in various ideologies

The Brexit Botnet and User-Generated Hyperpartisan News

In this paper we uncover a network of Twitterbots comprising 13,493 accounts that tweeted the U.K. E.U. membership referendum, only to disappear from Twitter shortly after the ballot. We compare active users to this set of political bots with respect to temporal tweeting behavior, the size and speed of retweet cascades, and the composition of their retweet cascades (user-to-bot vs. bot-to-bot) to evidence strategies for bot deployment. Our results move forward the analysis of political bots by showing that Twitterbots can be effective at rapidly generating small to medium-sized cascades; that the retweeted content comprises user-generated hyperpartisan news, which is not strictly fake news, but whose shelf life is remarkably short; and, finally, that a botnet may be organized in specialized tiers or clusters dedicated to replicating either active users or content generated by other bots

Early-stage [123I]beta-CIT SPECT and long-term clinical follow-up in patients with an initial diagnosis of Parkinson's disease

beta-CIT binding in both caudate nuclei was lower than in the group of patients with IPD. In addition, putamen to caudate binding ratios were higher in the group of APS patients. In spite of these differences, individual binding values showed considerable overlap between the groups. CONCLUSION: [(123)I]beta-CIT SPECT scanning in early-stage, untreated parkinsonian patients revealed a relative sparing of the caudate nucleus in patients with IPD as compared to patients later (re)diagnosed with APS. Nevertheless, the pattern of striatal involvement appears to have little predictive value for a later re-diagnosis of APS in individual case

PET and SPECT Imaging in Hyperkinetic Movement Disorders

Movement disorders can be classified in hypokinetic (e.g., Parkinson's disease, PD) and hyperkinetic disorders (e.g., dystonia, chorea, tremor, tics, myoclonus, and restless legs syndrome). In this chapter, we will discuss results from positron emission tomography (PET) and single photon emission computed tomography (SPECT) imaging studies in patients with tremor, tics, myoclonus, and restless legs syndrome. Most studies in patients with tremor included patients with essential tremor (ET): a bilateral, largely symmetric, postural or kinetic tremor mainly involving the upper limbs and sometimes the head. Other studies evaluated patients with orthostatic tremor (OT): an unusually high frequent tremor in the legs that mainly occurs when patients are standing still. Increased regional cerebral blood flow (rCBF) and increased glucose metabolism have been found in the cerebellum, sensorimotor cortex, and thalamus in both patients with ET and OT compared to controls. Both PET and SPECT studies have evaluated the dopamine system in patients with ET and OT. Most imaging studies in patients with ET showed no, or only subtle loss of striatal tracer binding to the dopamine transporter indicating that ET is not characterized by nigrostriatal cell loss. The serotonin and/or gamma-aminobutyric acid (GABA) systems may play a role in the pathophysiology of ET. PET and SPECT imaging of the dopamine and serotonin system in patients with OT showed no abnormalities. Tics, the clinical hallmark of Gilles de la Tourette syndrome (TS), are relatively brief and intermittent involuntary movements (motor tic) and sounds (phonic tic). The essential features of tics are that (1) they can be temporarily suppressed; after suppression a rebound usually occurs with a flurry of tics; (2) the patient experiences an urge to tic, and (3) the tic is followed by a short moment of relief. Using 18F-FDG PET, it was shown that TS is a network disorder where multiple brain areas are active or inactive at the same time. The exact composition of this network is yet to be determined. Using rCBF PET and SPECT many brain regions were found to be abnormal, however, tics mostly correlated with hypoperfusion of the caudate nucleus and cingulate cortex. Both dopamine and serotonin are likely to play a role in the pathophysiology of TS. It is hypothesized that TS is characterized by low serotonin levels that modulate increased phasic dopamine release. Myoclonus is defined as a brief muscle jerk and occurs in many neurologic and non-neurologic disorders. Imaging with PET and SPECT in patients with myoclonus mainly showed abnormalities consistent with the underlying disorder. We described PET and SPECT imaging results in patients in which myoclonus was a prominent symptom. Hypoperfusion and/or hypometabolism of the frontoparietal cortex was found in patients with negative epileptic myoclonus, Alzheimer's disease, corticobasal degeneration, Creutzfeldt-Jakob disease, fatal familiar insomnia, and posthypoxic myoclonus. Other findings that were frequently reported were decreased rCBF and/or glucose metabolism in the cerebellum and thalamus and abnormalities in the dopamine system. Restless legs syndrome (RLS) is defined as an urge to move the legs accompanied with an unpleasant sensation in the legs or in another body part that is especially present during the evening and night and that can be accompanied by periodic limb movements in sleep (PLMS). Imaging studies in these patients have mainly focused on the dopamine system. Most PET studies found decreased tracer binding to the dopamine transporter, although this was not found in SPECT studies. Both PET and SPECT studies showed conflicting results regarding dopamine D2/3 receptor binding: both increased and decreased tracer binding was reported. Furthermore, it is likely that the serotonin and opioid systems also play a role in the pathophysiology of RLS.</p
