Cultures of Citizenship in the Twenty-First Century: Literary and Cultural Perspectives on a Legal Concept
In the early twenty-first century, the concept of citizenship is more contested than ever. As refugees set out to cross the Mediterranean, European nation-states refer to "cultural integrity" and "immigrant inassimilability," revealing citizenship to be much more than a legal concept. The contributors to this volume take an interdisciplinary approach to considering how cultures of citizenship are being envisioned and interrogated in literary and cultural (con)texts. Through this framework, they attend to the tension between the citizen and its spectral others - a tension determined by how a country defines difference at a given moment

Fictocritical Cyberfeminism: A Paralogical Model for Post-Internet Communication
This dissertation positions the understudied and experimental writing practice of fictocriticism as an analog for the convergent and indeterminate nature of “post-Internet” communication as well a cyberfeminist technology for interfering and in-tervening in metanarratives of technoscience and technocapitalism that structure contemporary media. Significant theoretical valences are established between twen-tieth century literary works of fictocriticism and the hybrid and ephemeral modes of writing endemic to emergent, twenty-first century forms of networked communica-tion such as social media. Through a critical theoretical understanding of paralogy, or that countercultural logic of deploying language outside legitimate discourses, in-volving various tactics of multivocity, mimesis and metagraphy, fictocriticism is ex-plored as a self-referencing linguistic machine which exists intentionally to occupy those liminal territories “somewhere in among/between criticism, autobiography and fiction” (Hunter qtd. in Kerr 1996). Additionally, as a writing practice that orig-inated in Canada and yet remains marginal to national and international literary scholarship, this dissertation elevates the origins and ongoing relevance of fictocriti-cism by mapping its shared aims and concerns onto proximal discourses of post-structuralism, cyberfeminism, network ecology, media art, the avant-garde, glitch feminism, and radical self-authorship in online environments. Theorized in such a matrix, I argue that fictocriticism represents a capacious framework for writing and reading media that embodies the self-reflexive politics of second-order cybernetic theory while disrupting the rhetoric of technoscientific and neoliberal economic forc-es with speech acts of calculated incoherence. Additionally, through the inclusion of my own fictocritical writing as works of research-creation that interpolate the more traditional chapters and subchapters, I theorize and demonstrate praxis of this dis-tinctively indeterminate form of criticism to empirically and meaningfully juxtapose different modes of knowing and speaking about entangled matters of language, bod-ies, and technologies. In its conclusion, this dissertation contends that the “creative paranoia” engendered by fictocritical cyberfeminism in both print and digital media environments offers a pathway towards a more paralogical media literacy that can transform the terms and expectations of our future media ecology
Modern meat: the next generation of meat from cells
Modern Meat is the first textbook on cultivated meat, with contributions from over 100 experts within the cultivated meat community.
The Sections of Modern Meat comprise 5 broad categories of cultivated meat: Context, Impact, Science, Society, and World.
The 19 chapters of Modern Meat, spread across these 5 sections, provide detailed entries on cultivated meat. They extensively tour a range of topics including the impact of cultivated meat on humans and animals, the bioprocess of cultivated meat production, how cultivated meat may become a food option in Space and on Mars, and how cultivated meat may impact the economy, culture, and tradition of Asia
Repeated Game Dynamics in Population Protocols
We initiate the study of repeated game dynamics in the population model, in
which we are given a population of nodes, each with its local strategy,
which interact uniformly at random by playing multi-round, two-player games.
After each game, the two participants receive rewards according to a given
payoff matrix, and may update their local strategies depending on this outcome.
In this setting, we ask how the distribution of player strategies evolves with
respect to the number of node interactions (time complexity), as well as the
number of possible player states (space complexity), determining the stationary
properties of such game dynamics.
Our main technical results analyze the behavior of a family of Repeated
Prisoner's Dilemma dynamics in this model, for which we provide an exact
characterization of the stationary distribution, and give bounds on convergence
time and on the optimality gap of its expected rewards. Our results follow from
a new connection between Repeated Prisoner's Dilemma dynamics in a population,
and a class of high-dimensional, weighted Ehrenfest random walks, which we
analyze for the first time. The results highlight non-trivial trade-offs
between the state complexity of each node's strategy, the convergence of the
process, and the expected average reward of nodes in the population. Our
approach opens the door towards the characterization of other natural
evolutionary game dynamics in the population model
Behavior quantification as the missing link between fields: Tools for digital psychiatry and their role in the future of neurobiology
The great behavioral heterogeneity observed between individuals with the same
psychiatric disorder and even within one individual over time complicates both
clinical practice and biomedical research. However, modern technologies are an
exciting opportunity to improve behavioral characterization. Existing
psychiatry methods that are qualitative or unscalable, such as patient surveys
or clinical interviews, can now be collected at a greater capacity and analyzed
to produce new quantitative measures. Furthermore, recent capabilities for
continuous collection of passive sensor streams, such as phone GPS or
smartwatch accelerometer, open avenues of novel questioning that were
previously entirely unrealistic. Their temporally dense nature enables a
cohesive study of real-time neural and behavioral signals.
To develop comprehensive neurobiological models of psychiatric disease, it
will be critical to first develop strong methods for behavioral quantification.
There is huge potential in what can theoretically be captured by current
technologies, but this in itself presents a large computational challenge --
one that will necessitate new data processing tools, new machine learning
techniques, and ultimately a shift in how interdisciplinary work is conducted.
In my thesis, I detail research projects that take different perspectives on
digital psychiatry, subsequently tying ideas together with a concluding
discussion on the future of the field. I also provide software infrastructure
where relevant, with extensive documentation.
Major contributions include scientific arguments and proof of concept results
for daily free-form audio journals as an underappreciated psychiatry research
datatype, as well as novel stability theorems and pilot empirical success for a
proposed multi-area recurrent neural network architecture.Comment: PhD thesis cop
Synchronization of data in heterogeneous decentralized systems
Data synchronization is the problem of reconciling the differences between large data stores that differ in a small number of records. It is a common thread among disparate distributed systems ranging from fleets of Internet of Things (IoT) devices to clusters of distributed databases in the cloud. Most recently, data synchronization has arisen in globally distributed public blockchains that build the basis for the envisioned decentralized Internet of the future. Moreover, the parallel development of edge computing has significantly increased the heterogeneity of networks and computing devices. The merger of highly heterogeneous system resources and the decentralized nature of future Internet applications calls for a new approach to data synchronization. In this dissertation, we look at the problem of data synchronization through the prism of set reconciliation and introduce novel tools and protocols that improve the performance of data synchronization in heterogeneous decentralized systems.
First, we compare the analytical properties of the state-of-the-art set reconciliation protocols, and investigate the impact of theoretical assumptions and implementation decisions on the synchronization performance. Second, we introduce GenSync, the first unified set reconciliation middleware. Using GenSync's distinctive benchmarking layer, we find that the best protocol choice is highly sensitive to the system conditions, and a bad protocol choice causes a severe hit in performance. We showcase the evaluative power of GenSync in one of the world's largest wireless network emulators, and demonstrate choosing the best GenSync protocol under a high and low user mobility in an emulated cellular network. Finally, we introduce SREP (Set Reconciliation-Enhanced Propagation), a novel blockchain transaction pool synchronization protocol with quantifiable guarantees. Through simulations, we show that SREP incurs significantly smaller bandwidth overhead than a similar approach from the literature, especially in the networks of realistic sizes (tens of thousands of participants)
Financial reporting in Europe: Accounting for regulatory and technical challenges
This thesis explores the challenges facing financial reporting in Europe both regulatory and technical in nature. This has involved research into the background of European legislation and conducting face to face semi-structured interviews with senior elite actors from institutions governing the regulatory and technical arrangements of general-purpose financial reporting practice in Europe. European companies are required to disclose information about their financial affairs. The European legislation governing company financial reporting was delegated to the International Accounting Standards Board (IASB) by the EU institutions via Regulation 1606/2002. This thesis argues that European agencies (represented by EFRAG) are caught in a devolved regulatory relationship where the International Accounting Standards Board (IASB) has been able to assume a relatively strong self-regulatory position. This weakens the agency that European legislative institutions have over their own legislation with regards to financial reporting practice. This thesis argues this loss of agency by European institutions over their legislation governing accounting practice is not a fait accompli but is challenged and contested as European institutions seek and need a more co-regulated arrangement. A key argument developed in this thesis is that regulatory arrangements governing accounting practice are evolving in terms of the distribution of responsibilities and control over European financial reporting practice. To understand how the regulatory landscape governing European accounting practice is changing we employ an investigative lens that is grounded in accounting. This investigative lens employs three elements that are regarded in the literature review as significant technical challenges facing accounting practice in Europe. The first of these is retaining or not prudent accounting practice, the second is concerned with the development of non-financial reporting and the third, concerns with installing the public interest not just investor interests in financial disclosures. It is through this investigative lens that this thesis assesses the extent to which regulatory arrangements and agency governing accounting practice in Europe are shifting sands
