title: Development of an Actively Cooled Large Aperture Laser Amplifier at the GSI Helmholtzzentrum
Creators: name: Patrizio, Marco
Publisher: name: UNSPECIFIED
Year: 2020

description: The development of petawatt-class lasers during the last decades has resulted in a reduction of the size and cost of such systems. This development has lead to the adoption of petawattclass lasers at facilites world-wide for the study of matter in extreme states. The energy density achieved by such systems has lead to their use as direct drivers for particle acceleration, research on inertial confinement fusion and radiation therapy. Further uses for these systems were found in their application as secondary sources for X-rays, ions, electrons, protons and neutrons. This range of applications has lead to the use of petawatt-class lasers in national as well as university laboratories. The operation as direct and indirect sources requires high repetition rates to ensure the rapid reproducibility of respective results and increased statistics. While low energy petawatt lasers featuring pulse energies below 100 J are commercially available with repetition rates greater than 1 Hz, the repetition rate of high energy petawatt systems above 100 J pulse energy is limited by the cooling behaviour of their amplifier materials. Most high energy petawatt lasers utilize glass based gain media at apertures above 20 cm in their power amplifier elements. These large apertures are chosen to minimize the occuring intensities in the system and prevent damages to optical elements. However, the low thermal conductivity of glass leads to thermal equilibration times of the gain medium in the range of hours, thus featuring low repetition rates. The goal of this scientific work is the development of a glass based power amplifier element for high energy petawatt lasers featuring an active cooling scheme to reduce the thermal equilibration time of the gain medium to improve the repetitionrate of the laser. The targeted repetition rates are in the order of 1/5 min^-1 for a gain factor of 1.5 with a focus on the high quality and reproducibility of the transmitted wavefront. To this end, a concept was used that utilizes a laminar coolant flow between two discs of the gain medium to reduce the thermal load on the discs. A set of coolants was investigated to determine their thermal, kinematic, chemical and optical properties to qualify them for use in the prototype. Simulations of the cooling process in the prototype further lead to the discovery of a steady state between the heating and cooling of the gain medium between consecutive pulses. This steady state could be used to enable repeatable wavefront patterns at repetition rates of 1/5 min^-1 in the simulations. Experimental investigations of a full scale prototype model were further used to determine the leak tightness of the coolant seals as well as to conduct the first qualitative measurements of transmitted wavefronts.
The evolution of massive and very massive stars in clusters

description: The present paper reviews massive star (initial mass smaller than 120 M0) and very massive star (initial mass larger than 120 M0) evolution. I will focus on evolutionary facts and questions that may critically affect predictions of population and spectral synthesis of starburst regions. We discuss the ever-lasting factor 2 or more uncertainty in the stellar wind mass loss rates. We may ask ourselves if stellar rotation is one of the keys to understand the universe, why so many massive stars are binary components and why binaries are ignored or are considered as the poor cousins by some people? And finally, do ultra luminous X-ray sources harbor an intermediate mass black hole with a mass of the order of 1000 M0?

description: We present results of deep echelle spectrophotometry of the brightest knot of the HH202 in the Orion Nebula --HH202-S-- using the ultraviolet Visual Echelle Spectrograph (UVES). The high spectral resolution has permitted to separate the component associated with the ambient gas from that associated with the gas flow. We derive electron densities and temperatures for both components, as well as the chemical abundances of several ions and elements from collisionally excited lines, including the first determinations of Ca^{+} and Cr^{+} abundances in the Orion Nebula. We also calculate the He^{+}, C^{2+}, O^{+} and O^{2+} abundances from recombination lines. The difference between the O^{2+} abundances determined from collisionally excited and recombination lines --the so-called abundance discrepancy factor-- is 0.35 dex and 0.11 dex for the shock and nebular components, respectively. Assuming that the abundance discrepancy is produced by spatial variations in the electron temperature, we derive values of the temperature fluctuation parameter, t^2, of 0.050 and 0.016, for the shock and nebular components, respectively. Interestingly, we obtain almost coincident t^2 values for both components from the analysis of the intensity ratios of He I lines. We find significant departures from case B predictions in the Balmer and Paschen flux ratios of lines of high principal quantum number n. We analyze the ionization structure of HH202-S, finding enough evidence to conclude that the flow of HH202-S has compressed the ambient gas inside the nebula trapping the ionization front. We measure a strong increase of the total abundances of nickel and iron in the shock component, the abundance pattern and the results of photoionization models for both components are consistent with the partial destruction of dust after the passage of the shock wave in HH202-S.

Pseudoduality in Supersymmetric Sigma Models

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study the pseudoduality transformation in supersymmetric sigma models. We generalize the classical construction of pseudoduality transformation to supersymmetric case. We perform this both by component expansion method on manifold M and by orthonormal coframe method on manifold SO(M). The component expansion method yields the result that pseudoduality tranformation is not invertible at all points and occurs from all points on one manifold to only one point where riemann normal coordinates are valid on the second manifold. Torsion of the sigma model on M must vanish while it is nonvanishing on pseudodual manifold, and curvatures of the manifolds must be constant and the same. In case of super WZW sigma models pseudoduality equations result in three different pseudoduality conditions; flat space, chiral and antichiral pseudoduality.

description: We analyze the effects of noise correlations in the input to, or among, BCM neurons using the Wigner semicircular law to construct random, positive-definite symmetric correlation matrices and compute their eigenvalue distributions. In the finite dimensional case, we compare our analytic results with numerical simulations and show the effects of correlations on the lifetimes of synaptic strengths in various visual environments. These correlations can be due either to correlations in the noise from the input LGN neurons, or correlations in the variability of lateral connections in a network of neurons. In particular, we find that for fixed dimensionality, a large noise variance can give rise to long lifetimes of synaptic strengths. This may be of physiological significance.

description: Graphical models have been widely applied in solving distributed inference problems in sensor networks. In this paper, the problem of coordinating a network of sensors to train a unique ensemble estimator under communication constraints is discussed. The information structure of graphical models with specific potential functions is employed, and this thus converts the collaborative training task into a problem of local training plus global inference. Two important classes of algorithms of graphical model inference, message-passing algorithm and sampling algorithm, are employed to tackle low-dimensional, parametrized and high-dimensional, non-parametrized problems respectively. The efficacy of this approach is demonstrated by concrete examples.

Valutazione dell'impatto della farmacogenetica in ambito di Sanità  Pubblica. Analisi del polimorfismo genetico dell'enzima CYP2D6 metabolizzante xenobiotici.

description: Pharmacogenetic testing provides an outstanding opportunity to improve prescribing safety and efficacy. In Public health policy pharmacogenetics is relevant for personalized therapy and to maximize therapeutic benefit minimizing adverse events. 
CYP2D6 is known to be a key enzyme responsible for the biotransformation of about 25-30% of extensively used drugs and genetic variations in genes coding for drug-metabolizing enzymes might lead to adverse drug reactions, toxicity or therapeutic failure of pharmacotherapy. 
Significant interethnic differences in CYP2D6 allele distribution are well established, but immigration is reshaping the genetic background due to interethnic admixture which introduces variations in individual ancestry resulting in distinct level of population structure. The present thesis deals with the genetic determination of the CYP2D6 alleles actually present in the Emilia-Romagna resident population providing insights into the admixture process. A random sample of 122 natives and 175 immigrants from Africa, Asia and South America where characterized considering the present scenario of migration and back migration events. The results are consistent with the known interethnic genetic variation, but introduction of ethnic specific variants by immigrants predicts a heterogeneous admixed population scenario requiring, for drugs prescription and pharmacogenetics studies, an interdisciplinary approach applied in a properly biogeographical and anthropological frame. To translate pharmacogenetics knowledge into clinical practice requires appropriated public health policies, possibly guiding clinicians to evaluate prospectively which patients have the greatest probability of expressing a variant genotype.

description: Ab initio calculations and statistical mechanics are combined to elucidate the thermodynamics of H vacancies in MgH2. A general method based on a grand-canonical ensemble of defect configurations is introduced to model the exchange of hydrogen between crystalline MgH2 and gas-phase H2. We find that, at temperatures and hydrogen partial pressures of practical interest, MgH2 is capable of accommodating only very small concentrations of hydrogen vacancies, which consist mainly of isolated defects rather than vacancy clusters, contrary to what is expected from a simple energetic analysis.

"How do you spell critical eloquence" : investigations of poetry and prose in the theoretical writings of Gertrude Stein
Creators: name: Elsted, Crispin
Publisher: name: University of British Columbia
Year: 2010

description: Gertrude Stein's writing has not received an accurate critical reading. Critics have contented themselves with biographical studies, with attacks on her obscurity, and with philosophical or psychological theorizing which treats the writings as phenomena rather than as literature. A central preoccupation of Stein's writing is the difference between poetry and prose. Critics and readers have looked to Lectures in America, particularly to "Poetry and Grammar," for the clarification of her theories, but the complete answer to the problems of reading Stein cannot be found in the popular theoretical writings. In these she writes about her difficult work; Stein soon saw that she could only explain her most difficult writing in its own terms. In contrast to the "exegetical" Lectures in America and Narration, Stein created a remarkable body of "exemplary" writings, works which themselves exemplified the writing style they set out to explore. These "exemplary" works are concerned with the essential natures of poetry and prose. These works were written from 1923 to 1932, beginning with An Elucidation and ending with Stanzas in Meditation. The pieces collected in How To Write (1931) are concerned with prose. Through vocabulary, grammar, sentences and paragraphs, Stein explored the structural elements which make up prose. Her discovery that prose was inherently linear led her to suppose that the primary difference between prose and poetry might be that prose was progressive, and poetry, static. Her first attempt to "stop" poetry, in "Winning His Way," was mechanical and unsuccessful. It was only when she realized the use to which prepositions could be put that she was enabled to write Stanzas in Meditation, her greatest poem. In this, through her use of the relational elements of language, the sense of the writing moves between and among groups of objects, rather than from a beginning through a middle to an end, which is the basic movement of prose because of the linear quality of sentences and paragraphs. The poem's form, in closed stanzas, contributes to its non-linear effect. In Stanzas in Meditation, Stein unequivocally states her belief that the essence of the artistic object -- in this case, the poem itself -- can be realized by writing it "as a thing in itself without at all necessarily using its name." The struggles with language and form which make up the "exemplary" writings of Gertrude Stein enabled her to create a perfect marriage of technique and intention. Through this, she came to realize the importance of seeing that her subject was always in control" of its form, that her writing was "organic." Her final position on the subject was that "poetry and prose is not interesting. What is necessary now is not form but content."

Cosmological perturbations in generalized theories of gravity
Creators: name: Cerioni, Alessandro <1982>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: FIS/02 Fisica teorica, modelli e metodi matematici

description: The first part of the thesis concerns the study of inflation in the context of a theory of gravity called "Induced Gravity" in which the gravitational coupling varies in time according to the dynamics of the very same scalar field (the "inflaton") driving inflation, while taking on the value measured today since the end of inflation. Through the analytical and numerical analysis of scalar and tensor cosmological perturbations we show that the model leads to consistent predictions for a broad variety of symmetry-breaking inflaton's potentials, once that a dimensionless parameter entering into the action is properly constrained. We also discuss the average expansion of the Universe after inflation (when the inflaton undergoes coherent oscillations about the minimum of its potential) and determine the effective equation of state. Finally, we analyze the resonant and perturbative decay of the inflaton during (p)reheating.

The second part is devoted to the study of a proposal for a quantum theory of gravity dubbed "Horava-Lifshitz (HL) Gravity" which relies on power-counting renormalizability while explicitly breaking Lorentz invariance. We test a pair of variants of the theory ("projectable" and "non-projectable") on a cosmological background and with the inclusion of scalar field matter. By inspecting the quadratic action for the linear scalar cosmological perturbations we determine the actual number of propagating degrees of freedom and realize that the theory, being endowed with less symmetries than General Relativity, does admit an extra gravitational degree of freedom which is potentially unstable. More specifically, we conclude that in the case of projectable HL Gravity the extra mode is either a ghost or a tachyon, whereas in the case of non-projectable HL Gravity the extra mode can be made well-behaved for suitable choices of a pair of free dimensionless parameters and, moreover, turns out to decouple from the low-energy Physics.

The Copa : an introduction and commentary
Creators: name: Gruenewald, Frances J.
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis is two-fold: firstly, to make a general study of the Copa with a view to determining, as far as is possible, its authorship and date, and, secondly, to attempt a detailed exegesis of its contents. The first Chapter contains an introduction to the MSS tradition of the Appendix Vergiliana, and a brief discussion of the statements of Donatus and Servius concerning Vergilian authorship of the poems. In Chapter 2 the question of the authorship of the Copa is considered. The views of various scholars, who use as tests of authenticity studies of content and style, vocabulary, metre and parallel passages, are discussed. Particular worth is assigned the evidence afforded by the historical references to the Copa. The Chapter concludes that there is a strong case for Vergilian authorship. A possible date for the Copa is the subject of Chapter 3. Although there are varying opinions on this problem, it is found that certain features of metre (the apparent avoidance of the dissyllabic pentameter ending, for example), vocabulary (such as the use of diminutives and the present participle) and the use made of literary sources tend to indicate a "pre-Eclogue" date for the poem, that is, a date around 47 B.C. Chapter 4 contains a discussion of Vergil's study of Epicurean philosophy under Siro at Naples. The possibility that the Copa was written under the influence of Epicureanism is suggested; it appears that the poet manipulates various aspects of the philosophy for humorous purposes. In the Commentary, emphasis is concentrated on textual and lexical problems. There follow three short appendices and a bibliography.
Structure of the Southern Tyrrhenian subduction system: insights from seismological analysis of anisotropy and attenuation

description: The Southern Tyrrhenian subduction system shows a complex interaction among asthenospheric flow, subducting slab and overriding plate. To shed light on the deformations and mechanical properties of the slab and surrounding mantle, I investigated seismic anisotropy and attenuation properties through the subduction region. I used both teleseisms and slab earthquakes, analyzing shear-wave splitting on SKS and S phases, respectively. The fast polarization directions φ, and the delay time, δt, were retrieved using the method of Silver and Chan [1991. SKS and S φ reveal a complex anisotropy pattern across the subduction zone. SKS-rays sample primarily the sub-slab region showing rotation of fast directions following the curved shape of the slab and very strong anisotropy. S-rays sample mainly the slab, showing variable φ and a smaller δt. SKS and S splitting reveals a well developed toroidal flow at SW edge of the slab, while at its NE edge the pattern is not very clear. This suggests that the anisotropy is controlled by the slab rollback, responsible for about 100 km  slab parallel φ in the sub-slab mantle. The slab is weakly anisotropic, suggesting the asthenosphere as main source of anisotropy. To investigate the physical properties of the slab and surrounding regions, I analyzed the seismic P and S wave attenuation. By inverting high-quality S-waves t* from slab earthquakes, 3D attenuation models down to 300 km were obtained. Attenuation results image the slab as low-attenuation body, but with heterogeneous QS and QP structure showing spot of high attenuation , between 100-200 km depth, which could be due dehydration associated to the slab metamorphism. A low QS anomaly is present in the mantle wedge beneath the Aeolian volcanic arc and could indicate mantle melting and slab dehydration.

description: We have performed IRS low resolution 5-12 micron spectroscopy on a sample of galaxies selected to be at 3 distinct post-starburst evolutionary stages based on their optical spectral indices. The resulting IRS spectra show distinctive PAH emission line structures at 6.2, 7.7, 8.6 and 11.3 micron and little silicate absorption, indicative of ongoing star formation. However the PAH inter-line ratios, in particular the 11.3/6.2 micron and 7.7/6.2 micron ratio, show large variations. These variations are found to correlate with both time since the most recent starburst and AGN activity. We speculate that the evolution observed in these PAH ratios is related to an increase in AGN activity with time since star burst.

Reasoning with incomplete and imprecise preferences
Creators: name: Gelain, Mirco <1975>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: INF/01 Informatica

description: Preferences are present in many real life situations but it is often difficult to quantify them giving a precise value. Sometimes preference values may be missing because of privacy reasons or because they are expensive to obtain or to produce. In some other situations the user of an automated system may have a vague idea of whats he wants.
In this thesis we considered the general formalism of soft constraints, where preferences play a crucial role and we extended such a framework to handle both incomplete and imprecise preferences. In particular we provided new theoretical frameworks to handle such kinds of preferences.
By admitting missing or imprecise preferences, solving a soft constraint problem becomes a different task. In fact, the new goal is to find solutions which are the best ones independently of the precise value the each preference may have. With this in mind we defined two notions of optimality: the possibly optimal
solutions and the necessary optimal solutions, which are optimal no matter we assign a precise value to a missing or imprecise preference. We provided several algorithms, bases on both systematic and local search approaches, to find such kind of solutions. 
Moreover, we also studied the impact of our techniques also in a specific class of problems (the stable marriage problems) where imprecision and incompleteness have a specific meaning and up to now have been tackled with different techniques.
In the context of the classical stable marriage problem we developed a fair method to randomly generate stable marriages of a given problem instance.
Furthermore, we adapted our techniques to solve stable marriage problems with ties and incomplete lists, which are known to be NP-hard, obtaining good results both in terms of size of the returned marriage and in terms of steps need to find a solution.
Energetic and entropic cost due to overlapping of Turing-Hopf instabilities in presence of Cross Diffusion

description: A systematic introduction to nonequilibrium thermodynamics of dynamical instabilities is considered for an open nonlinear system beyond conventional Turing pattern in presence of cross diffusion. An altered condition of Turing instability in presence of cross diffusion can be best viewed in terms of the critical control parameter and wave number containing both the self and cross diffusion coefficients. Our main focus is on the entropic and energetic cost of Turing-Hopf interplay in stationary pattern formation. Depending on the relative dispositions of Turing-Hopf codimensional instabilities from the reaction-diffusion equation it clarifies two aspects: energy cost of pattern formation, especially how Hopf instability can be utilized to dictate a stationary concentration profile, and the possibility of revealing nonequilibrium phase transition. In the Brusselator model to understand these phenomena, we have analyzed through the relevant complex Ginzberg-Landau equation using the multiscale Krylov-Bogoiubov averaging method. Due to Hopf instability, it is observed that the cross diffusion parameters can be a source of huge change in free energy and concentration profiles.

Results presented here were obtained using the complete impulse approximation (CIA), which includes contributions of relativistic origin that appear as two-body corrections in a non-relativistic framework, such as "Z-graphs", but omits other two and three-body currents. We compare our results to non-relativistic calculations augmented by relativistic corrections of ${\cal O}(v/c)^2$.

Subjects: masers

description: Masers provide accurate velocity information on the movement of matter in the circumstellar shells (CSE) of late-type stars. We show here for the case of the Red Supergiant (RSG) VX Sgr, evidence for the radially outward movement of an H2O maser cloud traversing in 28 years a distance of ~90 au. The maser cloud (VXSgr-H2O-1987/14) was detected in 1987 at a distance of ~140 au from the central star moving with a velocity of v = 14 km/s away from the observer. The cloud was followed for decades during a 22 GHz H2O maser monitoring program at Medicina and Effelsberg until 2015, when the cloud was at a distance of ~230 au and had increased its velocity to v = 19 km/s. VXSgr-H2O-1987/14 was identified in MERLIN maps from 1994 and 1999 (Murakawa et al. 2003, Richards et al. 2012), and its location in the shell suggests an angle of 16+-1 degrees between the line-of sight and the outflow direction. This shows the ability of well-designed H2O maser monitoring programs to map wind motions in CSEs of RSGs at typical radial distances of 100-200 au.

Black holes and black strings in plane waves
Creators: name: Witt, Julian Le

Publisher: name: arXiv

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the construction of black holes and black strings in vacuum plane wave spacetimes using the method of matched asymptotic expansions. We find solutions of the linearised equations of motion in the asymptotic region for a general source on a plane wave background. We observe that these solutions do not satisfy our previously defined conditions for being asymptotically plane wave. Hence, the space of asymptotically plane wave solutions is restricted. We consider the solution in the near region, treating the plane wave as a perturbation of a black object, and find that there is a regular black string solution but no regular black hole solution.

Territory, territoriality and cultural change in an indigenous society : Old Crow, Yukon Territory
Creators: name: McSkimming, Robert James
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the research is to examine the impact of cultural, economic, and environmental factors on territory and territoriality in Old Crow, Yukon Territory. It investigates both the social and spatial changes in the society. An historical sketch provides the circumstances which led Kutchin Indians of the northern Yukon to eventually attach themselves to trading posts. The changing nature of resource-use patterns and the relationship between 'land-use' territory and 'perceived' territory is compared. The thesis framework, then, is to present an evolution of territory and territoriality in an isolated indigenous society. The territory of Old Crow is defined as that which reflects native use and perception. Territoriality, on the other hand, is the behaviour of dominating, controlling, and defending a specific space. Through use of the ecological approach the relationship between occupied territory and the group's image of its territory is explored. At the same time the present conditions of Old Crow's used and perceived territory is compared with past use and past expressions of territoriality. The ultimate purpose of this work is to shed light on the relationship between man and the environment with which he is intimately familiar. Little is known of the implications of territoriality on human behaviour and even less is known about the effect of territorial change on that behaviour. The thesis shows that territory cannot be separated from the behaviour of territoriality; the community's territory is that space which all members could identify as belonging to them. The group, essential to geographic study, is shown to be held together by common values toward the control and use of their territory and individual viewpoints could not be secured. The research supports the thesis that through cultural, social, and economic change the spatial extent of land used diminished and that there was a comparable drop in the spatial extent of territoriality. Furthermore, there has been an intensification of land use in the 'core' of the territory which has been paralleled by an intensification in the expressions of territoriality. However, although the total extent of the land is not used, it does not suggest that the people do not view the land as belonging to them. The land and its resources as perceived by the people of Old Crow are shown to be the only known and permanent commodities. Not only can the land provide a livelihood, but it is shown to be part of the people - a base for identity. In the final analysis it is the land itself now under attack which intensifies the relationship between Old Crow people and their land.
Ingénierie système d'un système d'information d'entreprise centré sur le produit basée sur un cadre de modélisation multi-échelles : application à un cas d'étude de l'AIP lorrain

description: Through its projects, the ?Atelier Inter-établissements de Productique Lorrain? (AIPL), as the owner and contractor of rank 1, is committed to provide his customers (teachers, training courses, students etc...) credible teaching materials at the scale of a real industrial flexible production of goods and services. In this changing context, its managerial team has chosen to suppress the CIM concept, which proposes an integrated enterprise, to steering distributed system information (SI), heterogeneous, autonomous and scalable depending on the ephemeral cooperation between industrial partners who now exchanges information and material flows. These aspects are studied in research on CRAN (Centre de Recherche en Automatique de Nancy ? Research Centre for Automatic Control) as part of a thesis based on the recursive aspect of systems and their models and their multi-scale aspects and multi-views, in a Model-Based-System-Engineering (MBSE) methodology proposal of an System-Engineering (SE) focused on the product. To validate this research, a MBSE has been implemented on a case study to AIPL: the "eLearning in eProduction? project.
Knowledge management in intelligent tutoring systems

Subjects: INF/01 Informatica

description: In the last years, Intelligent Tutoring Systems have been a very successful way for improving
learning experience. Many issues must be addressed until this technology can be defined mature.
One of the main problems within the Intelligent Tutoring Systems is the process of contents
authoring: knowledge acquisition and manipulation processes are difficult tasks because they
require a specialised skills on computer programming and knowledge engineering. In this thesis we
discuss a general framework for knowledge management in an Intelligent Tutoring System and
propose a mechanism based on first order data mining to partially automate the process of
knowledge acquisition that have to be used in the ITS during the tutoring process. Such a
mechanism can be applied in Constraint Based Tutor and in the Pseudo-Cognitive Tutor.
We design and implement a part of the proposed architecture, mainly the module of knowledge
acquisition from examples based on first order data mining. We then show that the algorithm can be
applied at least two different domains: first order algebra equation and some topics of C
programming language. Finally we discuss the limitation of current approach and the possible
improvements of the whole framework.
Atlante disciplinare della decostruzione. Dalla filosofia alla moda

Subjects: Derrida; Decostruzione; Moda; Decostruzionismo; Filosofia

description: Giocando sul duplice senso dell’espressione “dalla filosofia alla moda”, questo articolo si prefigge due obiettivi: da un lato, definire brevemente il concetto di decostruzione all’interno della filosofia di Jacques Derrida (1930-2004), indagandone il senso proprio e cercando di comprendere anche le ragioni che hanno portato al suo successo, oltre le aspettative dello stesso Derrida; secondariamente, illustrare appunto le varie traiettorie lungo le quali la decostruzione si è progressivamente trasformata in una “moda”, ossia in un metodo applicabile in diversi settori disciplinari. A questo punto, si cercherà quindi di fornire una sorta di “atlante disciplinare” della decostruzione, senza preoccuparsi di ortodossie filologiche, ma cercando di comprendere gli effetti prodotti dalla nozione di decostruzione. Gli ambiti presi in esame, particolarmente esemplari, saranno soprattutto la critica letteraria, l’architettura, la teoria dei media, la cultura pop e, infine, per dare un’ulteriore senso all’espressione “dalla filosofia alla moda”, la moda stessa, con un’attenzione specifica per Margiela e la scuola di Antwerp.
