description: Physically Unclonable Functions (PUF) are hardware-based security primitives whose unique challenge and response behavior serves as a "fingerprint" for device authentication, key generation, and anti-counterfeiting. Modeling and estimating the entropy of PUF responses to random challenges is the first step in formalizing the security of PUF-based cryptographic protocols. In this thesis, we consider the Arbiter PUF (APUF), a widely used and studied PUF construction. We propose a novel approach to modeling and estimating APUF entropy as a special type of randomness source, known as the (α,k) source. These sources had been previously used to model low-entropy rate biometric data, such as iris codes. We show that APUFs can be modeled as an (α,k) source by developing a framework to estimate extractable, inter-PUF, and intra-PUF entropies of a large number of simulated APUFs. We use the (α,k) source model of APUF to design a novel mutually Authenticated Key Exchange (mAKE) protocol that uses a single (large) multi-bit APUF response. Our mAKE has proved post-quantum cryptographic security in the random oracle model. The main building block of our construction is a new hash-based robust and reusable Fuzzy Extractor (rrFE) that is obtained by extending the reusable FE in Canetti et al. We implement our protocol and show its performance results.

description: Current political research on peace negotiations is fundamentally incomplete because it lacks the capacity to explain individual intents, choices and actions. This dissertation asks what impact individual negotiators, their approaches and choices of tactics have on peace talks and their outcomes. Individual people—be they representatives of rebel groups, non-governmental organisations or states—negotiate peace agreements. Consequently, an examination of individual motivations and actions in negotiations yields important knowledge. A fuller understanding of political negotiations, negotiators, and their tactics in Sierra Leone and Liberia is facilitated through a multidisciplinary consideration of the psychology, law and management studies literatures that consider individual motivations, biases, and behaviours. Based on extensive field research in Sierra Leone and Liberia, including numerous interviews with key players, I argue that individuals and their specific approaches and tactics influenced and altered the course of these peace negotiations, as well as their outcomes. Negotiators engaged in peace talks with underlying approaches (such as competitive, collaborative and cooperative styles) and then came to use various tactics (including shifting goalposts, hardball, silence, and bad faith), many of which were influenced by their innate biases and frames. Exploring these individuals’ conduct gives us previously unexplored insight into peace processes.
Personality in work humour: only when people are pleasant

description: The approaches taken in the development of most questionnaires in the area of humour studies involved the assumption of major dimensions and then the creation of items tailored for them, for example, Martin et al. (HSQ; 2003), Thorson and Powell (MSHS; 1993) and Booth-Butterfield and Booth-Butterfield (HOS; 1991). In particular, Ruch and Kohler's (STCI: 1998) model was strongly influenced by the Five Factor Model of personality (Costa & McCrae, 1992). Specific items within each questionnaire typically refer to a range of different environments, making the assumption that people behave somewhat similarly across situations. Theories of 'Emotional Labour' (Hoschchild, 2003) and 'Impression Management' (Goffman, 2004), however, suggested that in some situations personality characteristics are suppressed. The present study describes the development of an instrument specifically constructed to gauge a person's use of and reaction to humor in the work-place. Correlations with personality measures were found to be 'practically' significant in those scales which made up a 'Pleasant Climate' at work, whereas those scales which indicated an 'Unpleasant Climate' only showed trends in their relationships with personality measures. These findings accord with Foster's (2004) review that when groups are under pressure, conformity is essential to survival.

The Religion of Constantine I: An Analysis of the Modern Scholarly Hypotheses and Interpretations of the Contemporary Evidence

description: This thesis examines the hypotheses that modern historians have developed about the religion of the emperor Constantine I. Its aim is to elucidate the different methodologies historians have employed to interpret the contemporary evidence, which has often led to the development of conflicting hypotheses. The first chapter will discuss interpretations of the contemporary evidence that has led Barnes, Drake, and Bardill to hypothesize that Constantine converted to Christianity after the Battle of the Milvian Bridge. This chapter will primarily discuss possible familial and political influences and the narratives of Eusebius and Lactantius in order to elucidate the circumstances surrounding Constantine’s conversion. Then Constantine’s military insignia and his possible sacrifice after battle will be discussed in order to demonstrate any alterations in his religious mentality. The second chapter will examine the different interpretations of Constantine’s religious policy and legislation in order to clarify why Barnes proposes that Constantine became intolerant of religious diversity after his conversion, while Drake, Potter, and Bardill believe that he had remained as tolerant as he had been as a pagan. The third chapter will present the interpretations of the contemporary evidence that has led Burckhardt and Kee to assert that Constantine never converted to Christianity. This thesis will demonstrate that the vague and sometimes contradictory contemporary evidence supports multiple and even competing hypotheses. For this reason, there can be no “correct” answer about the religion of Constantine.

description: People diagnosed with acute myeloid leukemia (AML) face an acute life-threatening cancer for which treatment side effects, response, and progression may be unpredictable based on individual person and disease characteristics. Unfortunately, due to the aggressive and life-threatening nature of the disease, treatment decisions must be made within weeks of diagnosis, as untreated AML is universally fatal. However, recent literature has demonstrated that many people with AML have a discordant prognosis understanding wherein they overestimate their chance of cure compared to physician estimates. The purpose of this qualitative research was to gain a better understanding of individuals’ experience during their initial diagnosis and how these experiences influenced treatment decision-making. Using interpretive description methodology, 20 newly diagnosed AML participants were interviewed. Participants were universally shocked and overwhelmed due to the abrupt diagnosis and urgent treatment required. The complexities of AML as a disease resulted in a high volume of disease-specific information provided, impacted treatment options based on personal characteristics, and, in some cases, required treatment at specialized cancer centers. Most participants could not recall a clear definition of the term “cure” being provided in relation to their treatment goals. Participants voiced the need for dedicated time and continued reinforcement to learn disease-specific medical terminology. Participants found strength through personal coping strategies and support networks. Trusted relationships with healthcare providers were deemed essential; they were often seen as the most critical resource for disease information and, in some cases, were entrusted to make all treatment decisions.

description: Numerose dichiarazioni di Amelia Rosselli istituiscono un rapporto saldo tra l’ultimo suo poemetto, Impromptu, edito nel 1981, e le poesie di Ingeborg Bachmann. Alla luce dei documenti conservati nel Fondo Amelia Rosselli del Centro di Tradizione Manoscritta di Pavia, analizziamo le convergenze testuali tra le due produzioni poetiche e le premesse teoriche affini. Concludiamo che l’ispirazione alla Bachmann è piuttosto labile e che di contro l’insistenza nel proclamare un’ascendenza genetica da una parte convalida una corrispondenza maggiormente retrospettiva, dall’altra rientra nella strategia di autocostruzione di una figura autoriale da parte della Rosselli.

Creators: name: Pourzadi, Negar
Publisher: name: Science

Subjects: subject: Education--Sciences

description: The increasing emission of mercury (Hg) into the global environment necessitates a deeper understanding of its bioinorganic chemistry in mammals and the development of robust analytical methods to quantify inorganic mercury (Hg²⁺) and methylmercury (MeHg⁺) in environmental samples. This thesis addresses these challenges by exploring advanced separation and detection techniques. In the first project, anion-exchange high-performance liquid chromatography (AEXHPLC) coupled with flame atomic absorption spectrometry (FAAS) was employed to investigate the retention behavior of Hg²⁺ and MeHg⁺ across a pH range of 5.0–8.0, using a mobile phase containing 10 mM L-cysteine in 100 mM phosphate buffer. The addition of methanol (5–20%) to the mobile phase revealed that while the Hg²⁺ retention remained largely unaffected, the retention of MeHg⁺ was significantly reduced. A 15% methanol-containing mobile phase was identified as optimal to enable a rapid baseline separation of Hg²⁺ and MeHg⁺ in under 400 s. The method's robustness was validated using inductively coupled plasma atomic emission spectrometry (ICPAES), which allowed achieving a detection limit of 1.5 ppm for Hg²⁺ and 2.9 ppm for MeHg⁺. The developed method was successfully applied for wastewater spiked with both mercurials. In the second project, the interactions of gold nanoparticles (AuNPs) with plasma proteins were investigated to address challenges in targeted drug delivery. Size-exclusion chromatography (SEC) and transmission electron microscopy (TEM) revealed the formation of large (>670 kDa) AuNP-plasma protein aggregates, which would restrict effective drug delivery. To mitigate this, AuNPs were surface-modified with dithiols, including dithiothreitol (DTT), meso-2,3-dimercaptosuccinic acid (DMSA), and 2,3-dimercapto-1-propanesulfinic acid (DMPS). DMSAand DMPS-modified AuNPs demonstrated a superior reduction of the protein corona formation compared to DTT-modified AuNPs, suggesting their potential to enable their targeted delivery to the intended tissues. Excess dithiols, left over after the coating step, were found to mobilize iron from plasma metalloproteins, underscoring the need for their removal before any clinical application of dithiols-modified AuNPs. Together, these results advance the fields of environmental mercury analysis and nanomedicine by developing innovative separation techniques and surface modification strategies, to address critical challenges in environmental monitoring and targeted drug delivery.

Subjects: subject: Genomic LLM
subject: Computer Science

description: In genomics, much like human language, raw DNA sequences are not directly interpretable by most machine learning algorithms. Consequently, it is essential to transform these sequences into a numerical format suitable for computational processing. Recent research has concentrated on developing foundational models for DNA sequences, often relying on large-scale pre-training. However, given that DNA sequences consist of a finite set of elements, we argue that it is not always necessary to pre-train models from scratch to enhance the downstream tasking performance. Instead, significant improvements can be achieved through fine-tuning existing models. This study introduces a lightweight fine-tuning method aimed at enhancing genomic representations using unsupervised contrastive learning. We apply this method to DNABERT and DNABERT-2, two state-of-the-art genomic language models, and evaluate its performance on the publicly available GUE dataset. Our results demonstrate that this fine-tuning approach consistently surpasses the performance of pre-existing models.

description: In order to realize effective infotainment systems for vehicles, we need to have context-aware applications that use the latest (live) information for an enhanced user experience. Such up-to-date information is now abundantly available on the Internet, due to the explosive growth of the Web 2.0. In earlier times, it was difficult and expensive for vehicles to connect to the Internet. Recent advances in vehicular ad-hoc networks (VANETs) have enabled vehicles to connect to the Internet through road side infrastructures, with little to no additional cost. However, there are several problems with directly using Internet data in a vehicle, such as (1) Internet data sources have their own interfaces, which keep changing over time, needing frequent application updates, (2) information provided by multiple data sources needs to be preprocessed and fused before use, and (3) vehicles employ propriety platforms for infotainment systems, which makes an application update even more cumbersome. Furthermore, accessing multiple Internet sources may cause unnecessary overhead over the VANET bandwidth. In this thesis, we propose a cloud-based middleware framework for vehicular infotainment application development. The proposed framework follows service oriented architecture in which data filtering and fusion functionalities are delegated to the cloud. Data filtering and fusion reduce the data flow over VANET. Furthermore, because most the the processing is done on the cloud, the client becomes lightweight and loosely coupled with Internet resources and underlying platforms. We also propose a class based fusion method to combine information from multiple sources. The efficacy of the proposed framework is validated by developing an enhanced navigation (eDirection) application for the vehicle, as well as three infotainment applications: context-aware music, news, and weather.

description: Approximately 43% of Canada’s population reside in urban centres at most seismic risk.This research creates practical and proactive tools to support decision making in emergency management regarding earthquake risk. This proactive approach evaluates the potential impact of future earthquakes for informed mitigation and preparedness decisions. The overall aims are to evaluate a community’s operational readiness, reveal limitations and resources gaps in the emergency plan, test potential mitigation and preparedness strategies and provide a realistic earthquake scenario for training activities. Two models, the CanRisk injury model and a disaster Spatial Decision Support System (SDSS), were designed and developed to further evaluate seismic risk on a community scale. The injury model is an extension of the engineering-based CanRisk tool and quantifies an individual’s risk to injury, the number of injuries, and provides an injury profile of life-threatening injuries at the building scale. The model implements fuzzy synthetic evaluation to quantify seismic risk, mathematical calculations to estimate number of injuries, and a decision-matrix to generate the injury profile. The SDSS is an evidence-based model that is designed for the planning phase to evaluate post-earthquake emergency response. Loss estimations from Hazus Canada and the CanRisk injury model are combined with community geospatial data to simulate post-earthquake conditions that are important for immediate post-earthquake response. Fire services, search and rescue operations (including urban search and rescue and police services), emergency medical services, and relief operations are all modelled. A case study was applied to 27 neighbourhoods in Ottawa, Canada, using a M6.0 and M7.25 scenarios. The models revealed challenges to all emergency response units. A critical threshold exists between the M6.0 and M7.25 scenarios whereby emergency response moves from partial but manageable functionality to a complete system breakdown. The models developed in this research show great utility to emergency managers in Canada.

description: Tarnavazan is a four-movement piece that is shaped through a hybrid approach, blending Persian classical music and Western contemporary classical music. The Persian material is derived from the dastgāh Shur and dastgāh Nava (two Persian modes), while the Western material is based on a mode called the Partials mode, which is derived from the harmonic spectrum of the note D4 on the Tār (a traditional Persian instrument). The tempos of the first two movements are moderate—neither particularly fast nor slow—while the third and fourth movements are slower. The thesis contains an introductory essay explaining the composer’s approach to these materials as well as the performance score.

The surfaces of section $Σ$ that we construct are either Birkhoff sections, meaning that they intersect every sufficiently long orbit segment of the geodesic flow, or at least they have some hyperbolic components in $\partialΣ$ as limit sets of the orbits of the geodesic flow that do not return to $Σ$. In order to prove these theorems, we provide a study of configurations of simple closed geodesics of closed orientable Riemannian surfaces, which may have independent interest. Our arguments are based on the curve shortening flow.

description: Bedforms with wavelengths on the order of a metre made by the wind interacting with deformable sediment are found on Earth and Mars. The properties of metre-scale bedforms, which include their morphology, grain size, and structure, are known to vary significantly on each planet and between the two planets. This thesis uses a case study on Mars, a case study on Earth, a statistically-oriented review, and a philosophically-oriented review to provide new insights into how this variability can be understood and how it has been approached in previous literature. The Martian case study used a revised method to produce volumetric grain size distributions (GSDs) from images of Martian ripple sediment in Gale crater. These data are leveraged to argue that the variability of ripple sizes in Gale crater covaries with GSDs, implying that these ripples are analogous to the impact ripples and megaripples of Earth. The terrestrial case study expands the idea of GSDs as a primary control on metre-scale bedform variability and used a simple spatial analysis of bedform properties to show that variability can be partially understood as a function of sediment state varying over space. The statistical review addresses the ripple index and shows that it varies enormously between individual bedforms and locations. Consequently, the hypothesis that the ripple index allows for simple bedform classification is falsified. Finally, the philosophical review argues that bedform classification has not achieved the benchmark of a clear, paradigmatic science. From this premise, it argues that the terms large Martian ripple and transverse aeolian ridge and the largely inductive approach associated with them are flawed and have not been scientifically productive. The use of hypothesis-driven, falsifiable case studies is suggested to improve the present situation. As a whole, the findings of this thesis highlight that GSDs are likely the most under-theorized sources of metre-scale bedform variability, that understanding the statistical properties of bedform variability via residual analysis or spatial analysis is an underutilized approach in the science of metre-scale bedforms, and that more falsifiable, hypothesis-driven case studies are needed.

description: By taking up this research, I sought to acquire a deeper understanding of the cultural integration experiences of first-generation Canadian parents. In particular, I focused on the retention of cultural mores and norms that participants held when arriving in Canada and the integration (into their parenting) of the cultural mores and norms in their new country and the reasons associated with the aforementioned. I explored the internal thinking processes, and both participant self-perceptions and my perceptions of the cognitive changes of the first-generation immigrants who navigate the interplay between their culture of origin and Canadian culture when parenting their children. On the understanding that culture, over time and through exposure, affects cognition, the research focused solely on immigrants who have spent a minimum of 10 years in Canada and are functionally fluent in English. This allowed for sufficient exposure to the culture of their surroundings in Canada. This research is an autoethnography, which allowed me to draw from and reflect on my own experiences as both a first-generation immigrant child and parent. I believe this added richness to the study. An autoethnographic approach to this inquiry also allowed me to delve deeper into the thought processes of the participants through open-ended discussions, aiding a richer exploration of immigrant parent perception of cognitive changes and thought processes in relation to parenting choices. Based on the participants’ conscious analysis, not just of the changes they underwent, but also the reasons for the changes and the conscious choice to make the changes, I argue that all participants underwent a transformative learning journey. All participants were able to offer a perspective about their own perspective regarding the changes within them. The ability to do this is an essential condition of transformative learning.

description: Recent theoretical studies have shown that heavy-tails can emerge in stochastic optimization due to `multiplicative noise', even under surprisingly simple settings, such as linear regression with Gaussian data. While these studies have uncovered several interesting phenomena, they consider conventional stochastic optimization problems, which exclude decentralized settings that naturally arise in modern machine learning applications. In this paper, we study the emergence of heavy-tails in decentralized stochastic gradient descent (DE-SGD), and investigate the effect of decentralization on the tail behavior. We first show that, when the loss function at each computational node is twice continuously differentiable and strongly convex outside a compact region, the law of the DE-SGD iterates converges to a distribution with polynomially decaying (heavy) tails. To have a more explicit control on the tail exponent, we then consider the case where the loss at each node is a quadratic, and show that the tail-index can be estimated as a function of the step-size, batch-size, and the topological properties of the network of the computational nodes. Then, we provide theoretical and empirical results showing that DE-SGD has heavier tails than centralized SGD. We also compare DE-SGD to disconnected SGD where nodes distribute the data but do not communicate. Our theory uncovers an interesting interplay between the tails and the network structure: we identify two regimes of parameters (stepsize and network size), where DE-SGD can have lighter or heavier tails than disconnected SGD depending on the regime. Finally, to support our theoretical results, we provide numerical experiments conducted on both synthetic data and neural networks.

The use of BMP2 in surgical applications ranges from spinal fusion procedures to off-label uses such as dental implant augmentation. Currently, 1.5 mg/ml of BMP2 are necessary for these surgical procedures. The use of such relatively high concentrations of BMP2 leads to ectopic bone formation, provokes immune reactions hence rendering treatments ineffective and adds greatly to the overall expense of these therapeutic treatments. An engineered mutant BMP2 designed to have higher biological potency over the current wild type recombinant human BMP2 would reduce both dosages and costs in biomedical applications. The synthesis of a codon optimized DNA sequence designed for expression in rice would ensure high fidelity expression of such recombinant protein products in a biotech rice protein production platform. Although designed for rice recombinant protein expression, the codon optimized DNA sequence produces a fragment that corresponds to the theoretical fragment size of the C-terminal, mature monomeric peptide of BMP2 when expressed in E. coli. Results from in silico modelling of mutant BMP2 ligands docked with BMP receptors suggested that only certain mutations are tolerated at the L51 and D53 positions. Only certain mutants might have the same affinity for the receptor as the wild type due to steric interactions with other side chains on both the ligand itself and the receptor. For those mutants that did not possess steric conflicts, the recombinant L51-series BMP2 mutants produced a circular dichroism spectrum that was unique and differed from the spectrum of wild-type BMP2. C2C12 alkaline phosphatase activity assays of the wild-type BMP2 protein produced activity similar to previously published results, while the thirteen L51 substituted BMP2 mutant collection samples showed no bioactivity similar to a known negative activity mutant at this position. The expression potential of the codon optimized DNA BMP2 sequence in rice was calculated by comparing several computer generated sequences from online programs. Such models were used to assess whether the recombinant BMP2 possesses similar bioactivity to the BMP2 expressed in mammalian expression systems currently used.

description: L’articolo “Il sapere inquietante di Elvio Fachinelli: una psicoanalisi ‘anni Settanta’” propone una riflessione sull’avvento, lo sviluppo e la ricezione della psicoanalisi in Italia durante gli anni Settanta. L’analisi della figura dello psicoanalista italiano Elvio Fachinelli e della sua peculiare pratica psicoanalitica è finalizzata ad una più ampia comprensione del clima politico, sociale e culturale del decennio caldo italiano, a partire dal Sessantotto in poi. In questo periodo, infatti, la psicoanalisi di Elvio Fachinelli non rimane affatto una questione clinica avulsa dal contesto sociale, al contrario legandosi strettamente ad alcune delle questioni più peculiari e rappresentative dell’epoca considerata. Un’analisi delle posizioni di Fachinelli, dunque, oltre a mettere in luce svariati e significativi aspetti dei rapporti della psicoanalisi con il contesto socio-culturale degli anni Settanta, illuminerà quest’ultimo tramite una rilettura dal punto di vista di quel «sapere inquietante» –così Fachinelli definì la psicoanalisi- capace di restituire un’innovativa mappa del momento storico, del background culturale e dei suoi rapporti con il presente.

description: This work focuses on a class of general decentralized constraint-coupled optimization problems. We propose a novel nested primal-dual gradient algorithm (NPGA), which can achieve linear convergence under the weakest known condition, and its theoretical convergence rate surpasses all known results. More importantly, NPGA serves not only as an algorithm but also as a unified algorithmic framework, encompassing various existing algorithms as special cases. By designing different network matrices, we can derive numerous versions of NPGA and analyze their convergences by leveraging the convergence results of NPGA conveniently, thereby enabling the design of more efficient algorithms. Finally, we conduct numerical experiments to compare the convergence rates of NPGA and existing algorithms, providing empirical evidence for the superior performance of NPGA.
Lampi di possibili tempeste. Arte e letteratura nel Foucault degli anni Settanta.
Creators: name: Melegari, Diego
Publisher: name: Università degli Studi di Milano

description: Dopo avere rivestito un ruolo fondamentale negli scritti archeologici degli anni Sessanta, i riferimenti a pittura e letteratura sembrano scomparire dalla riflessione foucaultiana. Si tratta, in realtà, di uno slittamento dalle opere maggiori a brevi interventi in cui ad emergere è soprattutto il coinvolgimento soggettivo di Foucault. Questo passaggio, però, non è che un aspetto di una radicale riformulazione della funzione storico-ontologica precedentemente attribuita a letteratura e arte in favore di forme di esperienza non-strategica, dunque irriducibile al nesso potere-resistenza, e allo stesso tempo riattivabile come critica, anche politica, nel rapporto tra tempo storico e trasformazione della soggettività.

description: What would be the ultimate compliment for an exhibition devoted to abstraction in the digital age? A ripped remix of key phrases by Ihab Hassan or George Steiner on the aesthetics of silence, a surround sampling of Susan Sontag’s styles of radical will? No. In the early 21st century, abstraction is sick. Let me tell you why. [Introduction]

description: Il cosiddetto movimento del ’77, già negli anni della sua emersione ricondotto alle esperienze delle avanguardie artistiche del primo Novecento, riconfigurò i dispositivi di produzione-fruizione della cultura producendo un capovolgimento – orientato verso l’autorappresentazione politica dell’emergente proletariato giovanile – delle tradizionali categorie e mediazioni sociali ancora agenti nella società fordista.

description: Background: In a recent high-profile case study, we used functional magnetic resonance imaging (fMRI) to monitor improvements in motor function related to neuroplasticity following rehabilitation for severe traumatic brain injury (TBI). The findings demonstrated that motor function improvements can occur years beyond current established limits. The current study extends the functional imaging investigation to characterize neuromodulation effects on neuroplasticity to further push the limits. Methods: Canadian Soldier Captain (retired) Trevor Greene (TG) survived a severe open-TBI when attacked with an axe during a 2006 combat tour in Afghanistan. TG has since continued intensive daily rehabilitation to recover motor function, experiencing an extended plateau using conventional physical therapy. To overcome this plateau, we paired translingual neurostimulation (TLNS) with the continuing rehabilitation program. Results: Combining TLNS with rehabilitation resulted in demonstrable clinical improvements along with corresponding changes in movement evoked electro-encephalography (EEG) activity. High-density magneto-encephalography (MEG) characterized cortical activation changes in corresponding beta frequency range (27 Hz). MEG activation changes corresponded with reduced interhemispheric inhibition in the post-central gyri regions together with increased right superior/middle frontal activation suggesting large scale network level changes. Conclusions: The findings provide valuable insight into the potential importance of non-invasive neuromodulation to enhance neuroplasticity mechanisms for recovery beyond the perceived limits of rehabilitation.
La “gravità” dei Settanta: reticolarità e dissidenza in Gravity’s Rainbow di Thomas Pynchon

description: Uno dei cambiamenti radicali avvenuti negli anni Settanta in ambito statunitense riguarda il concetto di soggettività e la sua relazione con i sistemi politici, mediatici ed economici impegnati a produrla e controllarla. La deriva della controcultura in frange estremiste e la svolta conservatrice imposta dalla presidenza Nixon impongono un clima paranoico e cospiratorio, in cui il soggetto critico si scopre ganglio di larghe strutture ramificate che aspira a distruggere poteri oppresivi sovraindividuali, siano essi statali, militari o informativi, ri-negoziando di volta in volta la propria identità come libera o antagonistica. Tuttavia spesso la “dissidenza” rispetto a queste strutture finisce per essere un gesto fatuo, letale, o addirittura irrealizzabile. Le possibilità e i limiti di questa autodeterminazione politico-culturale del soggetto sono variamente espressi dalla letteratura americana del decennio, in particolare da Gravity’s Rainbow (1973) di Thomas Pynchon, in cui il mondo travolto dalla Seconda Guerra Mondiale appare come una metafora della rete di trame eterogenee, concatenate e impercettibili amplificate dalla Guerra Fredda e sostenute dal potere tecnologico-informativo destinato ad esplodere negli anni Settanta. Pynchon sintetizza la complessità e l’ambivalenza del sistema culturale postmoderno, nel quale l’individuo, sadicamente manipolato, fatica a concepire spazi di libertà e ad organizzare forme collettive di resistenza.
