description: We construct a class of 4D `yoga' (naturally relaxed) models for which the gravitational response of heavy-particle vacuum energies is strongly suppressed. The models contain three ingredients: (i) a relaxation mechanism, (ii) a very supersymmetric gravity sector coupled to matter for which supersymmetry is non-linearly realised, and (iii) an accidental approximate scale invariance expressed through the presence of a low-energy dilaton supermultiplet. All three are common in higher-dimensional and string constructions and although none suffices on its own, taken together they can dramatically suppress the net vacuum-energy density. The dilaton's {\it vev}~$τ$ determines the weak scale $M_W \sim M_p/\sqrtτ$. We compute the potential for $τ$ and find it can be stabilized in a local de Sitter minimum at sufficiently large field values to explain the electroweak hierarchy, doing so using input parameters no larger than $O(60)$ because the relevant potential arises as a rational function of $\lnτ$. The de Sitter vacuum energy at the minimum is order $c\, M_W^8 \propto 1/τ^4$, with $c \ll O(M_W^{-4})$. We discuss how to achieve $c \sim 1/M_p^4$ as required by observations. Scale invariance implies the dilaton couples to matter like a Brans-Dicke scalar with dangerously large coupling yet because it comes paired with an axion it can evade bounds through the novel screening mechanism described in {\tt ArXiV:2110.10352}. Cosmological axio-dilaton evolution predicts a natural quintessence model for Dark Energy, whose evolution can realize recent proposals to resolve the Hubble tension, and whose axion contributes to Dark Matter. We summarize inflationary implications and some remaining challenges, including the unusual supersymmetry breaking regime used and the potential for UV completions of our approach.

description: We present an analytic approach to the dynamical friction (DF) acting on a circularly moving point mass perturber in a gaseous medium. We demonstrate that, when the perturber is turned on at $t=0$, steady-state (infinite time perturbation) is achieved after exactly one sound-crossing time. At low Mach number $\mathcal{M}~\ll~1$, the circular-motion steady-state DF converges to the linear-motion, finite time perturbation expression. The analytic results describe both the radial and tangential forces on the perturbers caused by the backreaction of the wake propagating in the medium. The radial force is directed inward, toward the motion centre, and is dominant at large Mach numbers. For subsonic motion, this component is negligible. For moderate and low Mach numbers, the tangential force is stronger and opposes the motion of the perturber. The analytic solution to the circular-orbit DF suffers from a logarithmic divergence in the supersonic regime. This divergence appears at short distances from the perturber solely (unlike the linear motion result which is also divergent at large distances) and can be encoded in a maximum multipole. This is helpful to assess the resolution dependence of numerical simulations implementing DF at the level of Liénard-Wiechert potentials. We also show how our approach can be generalised to calculate the DF acting on a compact circular binary.

description: We show, from a diabatic analysis of Lattice results for string breaking, that mixing of $Q\bar{Q}$ with open-flavor meson-meson configurations may be expressed through a mixing potential which is order $1 / m_{Q}$. A relation between the minimum string breaking energy gap and the string tension comes out naturally. Using this relation, and matching the energy gap for $b\bar{b}$ with Lattice QCD data, we study the mixing in the $c\bar{c}$ case without any additional parameter. A $1^{++}$ bound state very close below the ${D}^{0}\bar{D}^{\ast 0}$ threshold, in perfect correspondence with $χ_{c1}(3872)$, is predicted.

Io e l'altro (Io) tra bilinguismo, biculturalismo e identità culturale del Sé "rappato" di seconda generazione

description: This work aims to analyze the continuously increasing rap songs of second-generation immigrants, from a multidisciplinary perspective and on an exclusively synchronic level. The second generation rappers are children of immigrants or mixed couples, born and raised in Italy, who use the language of rap as a means of constructing their own identity. Suspended "between two cultures" (Baumann 1), or between two worlds, the singers create in their songs a "third space" (Bhabha 54-56) steeped in contaminations and creolizations. Furthermore, the simultaneous use of two or more codes makes coexist in their lyrics a plurality of languages that has now become a "new plurality" (Ferrari 157). It does not reflect a specific belonging to a place or culture, but the desire to situate oneself between two places. Since this is a in continuously expanding phenomenon, the examples are numerous. For the purpose of this paper we analysed a selection of songs of five of the second-generation rappers that are much followed at a social network level. We then conducted a linguistic analysis aimed at investigating on the peculiar presence in the lyrics of both Italian and "immigrant languages" (Vedovelli 97). The cross-linguistc influence phenomena (code-switching and code-mixing) together with the choice of lexemes with a strong emotional connotation act as identity representation tools. The identity is always based on duality and on the conflict that arises from the continuous relating of the Self with the Other and from the exchange between the Self and the Other, in which the otherness refers to both the others and the other part of the Self.

Mostrare la nevrosi: la polarità del Sintomo fra Scarto e Riattivazione
Creators: name: Colopi, Valentina
Publisher: name: Altre Modernità
Year: 2020

description: Since the end of the Nineteenth Century the hysterical body has progressively invaded the medical and artistic European scene, giving birth to different kinds of ambivalent performances. On the one hand, the 'staging' of hysteria represented the attempt of power to reject the sick subject in order to cure his or her pathology and protect the collectivity by defusing its mechanism of sick mimesis. On the other hand, the hysterical body started to be investigated and performed also by the performing arts, which considered it as a manifestation of a positive and creative kind of performance: a physical-verbal alternative, a gestural language as well as a form of social iconic communication. As a consequence, the theatre scene grew more "nervous" and sick, while the most important performers of the period became more and more similar to the hysterics immortalized by medical photos. The pathological gesture prevailed and, as a consequence, theatre was obliged to deflagrate into new and hybrid languages. Thanks to its polarity, the hysterical body, sick or misshapen - an upsetting but, at the same time, attractive object - was expressed by a pantomimic and grotesque type of staging - the Grand-Guignol - which promoted a gratifying performance of pathology. By adapting to the times and changing its shape, hysteria passed into Antonin Artaud's body-theatre. Nowadays, its pathological gesture seems to have been scientifically subdued and reabsorbed into the norm of bodies.

description: The detection of artificial satellite thermal emission at millimeter wavelengths is presented using data from the 3rd-Generation receiver on the South Pole Telescope (SPT-3G). This represents the first reported detection of thermal emission from artificial satellites at millimeter wavelengths. Satellite thermal emission is shown to be detectable at high signal-to-noise ratios on timescales as short as a few tens of milliseconds. An algorithm for downloading orbital information and tracking known satellites given observer constraints and time-ordered observatory pointing is described. Consequences for cosmological surveys and short-duration transient searches are discussed, revealing that the integrated thermal emission from all large satellites does not contribute significantly to the SPT-3G survey intensity map. Measured satellite positions are found to be discrepant from their two-line element (TLE) derived ephemerides up to several arcminutes which may present a difficulty in cross-checking or masking satellites from short-duration transient searches.
Eccessi di vita: autobiografismi tra risonanza e marginalità

Publisher: name: Altre Modernità
Year: 2020

description: Although memoirs, confessions and diaries have gained huge popularity, life writing’s definition and values are not completely consolidated, as suggested by the unlimited discussion of autobiography and the different forms this genre can acquire. Moreover, since more and more non-professional authors have been publishing narratives about themselves, critics still tend to neglect these texts, which they often consider naïf and rough. This essay seeks to shed light on the dynamic mechanisms which exclude or include life writing in the literary realm. Aspects such as the influence of canonical autobiographies, the selective processes and the function of narrativity and will be scrutinized as well. The corpus will not only focus on texts by well-known authors (Annie Ernaux, Hervé Guibert), but also on works by ‘one hit wonders’ autobiographers (Fritz Zorn, Lucy Grealy).

description: Since its first demonstration in graded-index multimode fibers, spatial beam self-cleaning has attracted a growing research interest. It allows for the propagation of beams with a bell-shaped spatial profile, thus enabling the use of multimode fibers for several applications, from biomedical imaging to high-power beam delivery. So far, beam self-cleaning has been experimentally studied under several different experimental conditions. Whereas it has been theoretically described as the irreversible energy transfer from high-order modes towards the fundamental mode, in analogy with a beam condensation mechanism. Here, we provide a definitive theoretical description of beam self-cleaning, by means of a semi-classical statistical mechanics model of wave thermalization. This approach is confirmed by an extensive experimental characterization, based on a holographic mode decomposition technique, employing laser pulses with temporal durations ranging from femtoseconds up to nanoseconds. An excellent agreement between theory and experiments is found, which demonstrates that beam self-cleaning can be fully described in terms of the basic conservation laws of statistical mechanics.
“American National Literature. Is there any such thing – or, can there ever be?”: Walt Whitman e le strategie di selezione del canone tra discorso metaletterario e politica culturale
Creators: name: Razzi, Francesca
Publisher: name: Altre Modernità
Year: 2020

description: The present contribution deals with the strategies of selection, which lay at the basis of the so-called national literary canons, by examining a number of critical prose essays written by the American poet Walt Whitman. Under a sociological perspective, Whitman’s essays may be considered not only as mere literary texts, but also as a specimen of meta-literary discourse, fostering the development of the American literary field of the late-Nineteenth century, in its entangled relations with and within the literary marketplace (authors, readers, and publishing industry). Through their publication on the periodical press, Whitman’s essays enact complex strategies of selection, aimed at constructing a national literature by means of references to previous traditions – either by choosing or discarding their aesthetic and ideological paradigms. At the same time, the cultural role performed by magazines and newspapers in post-Civil War America testifies to the double process of legitimization of literary authorship, and commodification of the literary work available to a wide audience mainly made up of middle-class readers.

description: Chiral phonons are vibrational modes in a crystal that possess a well-defined handedness or chirality, typically found in materials that lack inversion symmetry. Here we report the discovery of chiral phonon modes in the kagome ferromagnetic Weyl semimetal Co3Sn2S2, a material that preserves inversion symmetry but breaks time-reversal symmetry. Using helicity-resolved magneto-Raman spectroscopy, we observe the spontaneous splitting of the doubly degenerate in-plane Eg modes into two distinct chiral phonon modes of opposite helicity when the sample is zero-field cooled below the Curie temperature, in the absence of an external magnetic field. As we sweep the out-of-plane magnetic field, this Eg phonon splitting exhibits a well-defined hysteresis loop directly correlated with the material's magnetization. The observed spontaneous splitting reaches up to 1.27 cm-1 at low temperatures, progressively diminishes with increasing temperature, and completely vanishes near the Curie temperature. Our findings highlight the role of the magnetic order in inducing chiral phonons, paving the way for novel methods to manipulate chiral phonons through magnetization and vice versa. Additionally, our work introduces new possibilities for controlling chiral Weyl fermions using chiral phonons.
Il caso “L’Iguana”: scelte editoriali, scarti, misteri e soluzioni da un testo di Anna Maria Ortese
Creators: name: Ceravolo, Marco
Publisher: name: Altre Modernità
Year: 2020

description: Anna Maria Ortese’s L’Iguana is one of the most enigmatic pieces of her entire work. At the National Archive of Naples, where all Ortese’s unpublished works are kept, one may find a large collection of papers on L’iguana: scraps, notes and several discarded finals. Initially, in 1963, eight chapters of the book were published by the magazine “Mondo”. L’Iguana went through a difficult destiny: three different publishing houses contended over its publication, and finally the novel was published by Vallecchi Editions in 1965. Later on, in 1980, Ortese wrote to Natalia Ginzburg, mentioning a “new version of Iguana, entitled Miseria e solitudine di una Iguana” (Spadaccini, Archivio di Stato di Napoli, 2006, doc. 54). The present study starts from the editorial case of the novel, passing through the investigation of the original papers from Fondo Ortese: our attempt is to examine Anna Maria Ortese’s modus operandi, taking in consideration the different editions, revisions and the discarded finals. In order to get a better understanding of this mysterious and grotesque novel, we will follow the notes written by the author, marking the history of the author’s scraps, the reasons which led Ortese to the different ending.

Censura, autocensura e malapartiana revisione: storie di una corrispondenza scartata e recuperata ne Il Volga nasce in Europa

description: Between 1941 and 1942 Curzio Malaparte, one of the most troubled writers in Fascist Italy, was sent by Il Corriere della Sera on the Russian Front as a war correspondent, to write under the supervision of redactor Aldo Borelli and the harsh control of fascist censorship. His correspondences, collected in The Volga Rises in Europe in 1943, were extraordinarily vivid and sharp; nevertheless, too many elements have led to tarnish the memory of this work, as the unstable credit earned by the author with his readers, and the editorial itinerary of the collection, which was published, censored and modified in an ideologically sensitive time. Several studies have dealt with this collection, judging in different ways the honesty of its author but always acknowledging its literary and historical value. In this essay, we try to retrace the philological history of The Volga Rises in Europe, showing that not all the changes operated by the author on the text are led by the attempt at distancing himself from Fascism. One certain correspondence, “Una tomba nei sobborghi di Leningrado”, which has been reinserted in the latest edition, has probably a whole different story. The essay intends to present some hypotheses on this story and to show how this correspondence can be considered as a sensitive topic for all involved parts: the subject, the censorship, and the author himself.

description: The phase function is a key element of a light propagation model for Monte Carlo (MC) simulation, which is usually fitted with an analytic function with associated parameters. In recent years, machine learning methods were reported to estimate the parameters of the phase function of a particular form such as the Henyey-Greenstein phase function but, to our knowledge, no studies have been performed to determine the form of the phase function. Here we design a convolutional neural network to estimate the phase function from a diffuse optical image without any explicit assumption on the form of the phase function. Specifically, we use a Gaussian mixture model as an example to represent the phase function generally and learn the model parameters accurately. The Gaussian mixture model is selected because it provides the analytic expression of phase function to facilitate deflection angle sampling in MC simulation, and does not significantly increase the number of free parameters. Our proposed method is validated on MC-simulated reflectance images of typical biological tissues using the Henyey-Greenstein phase function with different anisotropy factors. The effects of field of view (FOV) and spatial resolution on the errors are analyzed to optimize the estimation method. The mean squared error of the phase function is 0.01 and the relative error of the anisotropy factor is 3.28%.

"Us Refugees, the Flotsam and Jetsam of Death”: the Monsters of Being Human as Ethnic Outsiders, Migrants and Asylum Seekers
Creators: name: Villa, Ilaria
Publisher: name: Altre Modernità
Year: 2020

description: Being Human was a British television series broadcast by BBC Three between 2008 and 2013. Its main characters are a ghost, a vampire and a werewolf, who live together and try to lead a normal life among humans; however, their integration into society is a constant struggle. Since Being Human is centred on inclusion, exclusion and belonging, the story evokes real-life situations of marginalisation; following Lampert-Weissig’s suggestion about the relevance of the characters’ ethnicity (an Irish, a Jewish and a mixed-race person), which makes them “double outsiders” (65), my essay proposes an analysis of the three main characters in seasons 1-3 of Being Human as tropes for ethnic outsiders, migrants and asylum seekers in the UK. I will first consider each character individually, because each one of the three tropes (werewolf, vampire, ghost) has its own history and evolution in folklore, literature and cinema and, therefore, each one of the three protagonists is particularly suited for introducing different perspectives on foreignness and marginalisation. I will then discuss how Being Human addresses the issue of social exclusion and how the show’s final message, while progressive at first sight, is actually problematic and ambiguous.

description: Magnetic dipole strength functions are determined for the series of germanium isotopes from $N = Z = 32$ to $N$ = 48 on the basis of a large number of transition strengths calculated within the shell model. The evolution of the strength with increasing neutron number in the $1g_{9/2}$ orbital is analyzed. A bimodal structure comprising an enhancement toward low transition enery and a resonance in the region of the scissors mode is identified. The low-energy enhancement is strongest near closed shells, in particular at the almost completely filled $1g_{9/2}$ orbital, while the scissorslike resonance is most pronounced in the middle of the open shell, which correlates with the magnitude of the also deduced electric quadrupole transition strengths. The results are consistent with previous findings for the shorter series of iron isotopes and proves the occurrence and correlation of the two low-lying magnetic dipole modes as a global structural feature.

“Ask the Author”: notes on authorial philology and contemporary playwriting

description: Correspondence between the company and the playwright, different versions of the script, rehearsal notes, prompt books: a theatre’s archive can preserve the traces of a creative workshop ideally characterized by an ongoing dialogue, of which the recurring reminder “ask the author” can be a telltale sign. Additions, changes and cuts, in the case of a text intended for performance, are generally negotiated by the writer and other members of the creative team according to their respective style choices, knowledge and needs, so the analysis of the resulting palimpsest can help not only to unveil the story of a single play and to assess the role of variants and variations (when present), but also to reconstruct such complex artistic practices as those of contemporary theatre. In the present paper I mean to illustrate and discuss opportunities and problems of authorial philology applied to contemporary playwriting with particular reference to the new texts produced by Shakespeare’s Globe Theatre and the documents held by its archive.

description: Current fluctuations related to the discreteness of charge passing through small constrictions are termed shot noise. This unavoidable noise provides both advantages - being a direct measurement of the transmitted particles' charge, and disadvantages - a main noise source in nanoscale devices operating at low temperature. While better understanding of shot noise is desired, the technical difficulties in measuring it result in relatively few experimental works, especially in single-atom structures. Here we describe a local shot-noise measurement apparatus, and demonstrate successful noise measurements through single-atom junctions. Our apparatus, based on a scanning tunneling microscope operates at liquid helium temperatures. It includes a broadband commercial amplifier mounted in close proximity to the tunnel junction, thus reducing both thermal noise and the input capacitance that limit traditional noise measurements. The full capabilities of the microscope are maintained in the modified system and a quick transition between different measurement modes is possible.

Storie di rifiuti, rifiuti nelle storie: due prospettive sullo scarto
Creators: name: Carati, Simone
Publisher: name: Altre Modernità
Year: 2020

description: Scrap, as a residual and not easy to place element, is a common topic in a great number of works in contemporary fiction, where it takes on a precise meaning: waste. This paper aims to analyse this theme focusing on some emblematic passages of two maximalist novels published at the end of 20th Century: Underworld, by Don DeLillo, and Infinite Jest, by David Foster Wallace. In the former, Nick Shay’s job consists of the disposal of waste, which becomes something that questions the concept of functionality (Scaffai 139). Moreover, waste becomes the tangible equivalent of adolescent traumas, surfacing all over again. In Infinite Jest, the stories told by the drug addicts who live in Ennet House, the real “scraps” of the novel, represent an effort made by characters to re-elaborate narratively their suffering, giving voice to their own experience. Waste symbolizes the return of the rejected, what was relegated to the margins of the community or characters' lives; it becomes a means to advocate for space in the complex plots of the novels.

Gli “oggetti-spazzatura” ne L’Herbier des villes e Lieux di Georges Perec
Creators: name: Iannetti, Sara
Publisher: name: Altre Modernità
Year: 2020

description: In the second half of the nineteenth century appears the figure of the "chiffonnier", daughter of the modern metropolis, where, according to Benjamin, the fragments of the consumer society are deposited and preserved every day. Baudelaire gives the first definition of the "ragtag" in a famous passage of the essay Du vin et du haschisch of 1851, useful for the analysis of two Perecquien projects, L'Herbier des villes and Lieux, which present themselves as real archives. Perec collected the derisory traces of urban life, to which we generally do not give any importance, cinema, subway, museum tickets, posters, flyers, receipts that constitute "signes d'ancrage" or "objets témoins" in constant dialogue with the writing. Especially since the 1960s, the art world, by eliminating every distance that separates it from everyday life, reintegrates the junk object. Perec's work thus fits into a wider artistic revolution, which manifests a different attention to the value of everyday objects. Starting from the theoretical observations of Foucault, Derrida, Benjamin and Baldacci, the contribution proposes a reflection on the memorial practices and on the forms of knowledge that distinguish the two Perecquien projects, which have remained unfinished.

description: The primordial Universe might be highly inhomogeneous. We perform the 3+1D Numerical Relativity simulation for the evolution of scalar field in an initial inhomogeneous expanding Universe, and investigate how it populates the landscape with both de Sitter (dS) and AdS vacua. The simulation results show that eventually either the field in different region separates into different vacua, so that the expanding dS or AdS bubbles (the bubble wall is expanding but the spacetime inside AdS bubbles is contracting) come into being with clear bounderies, or overall region is dS expanding with a few smaller AdS bubbles (which collapsed into black holes) or inhomogeneously collapsing.

Long Live the Weeds!: gli scarti vegetali nella poesia di Theodore Roethke degli anni ’30 e ’40
Creators: name: Paparoni, Ginevra
Publisher: name: Altre Modernità
Year: 2020

description: Vegetal flotsam – undesirable or discarded and dead vegetation – holds and important position in the poetic imagery of Theodore Roethke’s production of the 1930s and ’40. In Roethke’s first two volumes (Open House and The Lost Son and Other Poems), weeds and dead plants are the protagonists of poems that are strikingly different from each other in style and content. “Long Live the Weeds” – Roethke’s “rewriting” of Gerard Manley Hopkins’ “Inversnaid” – expresses a reassuring worldview where “the ugly of the universe” is a necessary and even joyfully welcomed part of the universe’s natural order. In the “Lost Son Narratives” the faith in such idea is cyclically lost and reconquered by the conscience perceiving nature in its concreteness. In the Greenhouse Poems the interaction between the crude and simple representation of uprooted and decomposing plants, in particular poems like “Weed Puller” and “Flower Dump”, and the sequence’s portrayal of the entire vital balance of the greenhouse conveys an even more problematic and open-ended view of nature. As a thorough analysis and comparison of “Long Live the Weeds!” (first published in 1936) and sections the two aforementioned poetic sequences (published in their entirety in 1948) will show, in Roethke’s first two collections, the evolution of his modes of representation of vegetal flotsam mirrors the evolution of his conception of nature and existence.

Il collezionismo degli scarti e resti: chiffonniers contemporanei
Creators: name: Valdinoci, Francesca
Publisher: name: Altre Modernità
Year: 2020

description: Since the 19th century, along with the expansion of the capitalist system, we see a growing attention to industrial waste as well as an increasing interest for the refuses of history. The recovery of these fragments, left aside from the official narration, represents the condemnation of a selection system which has often been an instrument of power and oppression. Thanks to the developing awareness of this mechanism, art takes on the task of exhuming and enhancing those waste materials through an archaeological perspective. The chiffonier, characterized by this archaeological vocation, is an emblematic figure of Paris during the Second Empire and a collector of the fragments of history. The main characters of Homer & Langley by Doctorow and Raymond Isidore e la sua cattedrale by Franzosini are contemporary chiffonniers who, through their works, create a monument to the objects of waste, while these biographical fictions rehabilitate the narration of these “wasted lives” dominated by mental alienation

Percy Bysshe Shelley’s Italian Poems. Flotsam in the Canon, Fragments in a Corpus
Creators: name: Canani, Marco
Publisher: name: Altre Modernità
Year: 2020

description: The concept of the literary canon has been extensively debated and questioned as the result of a process of critical negotiation including scholarly discourse as well as editorial and didactic practices. This complex network of cultural, social, and economic factors is also crucial to defining an author’s own canon, that is, the body of works that best identifies a writer’s authorial identity. With specific reference to English Romanticism, Percy Bysshe Shelley’s works represent a relevant case in point, marked as they are by a long and established tradition of textual studies and critical editions. Interestingly, Shelley’s notebooks dating to 1820-1821 include a number of poems and fragments written in Italian, either as original compositions or, more frequently, as attempts at self-translation. Until recently, Shelley’s “Italian corpus” has received only marginal critical attention, viewed as best as a token of his infatuation with Emilia Viviani while he was living in Pisa. This article examines Shelley’s Italian poetic corpus in order to discuss its relevance within his oeuvre, and it argues that these Italian fragments provide significant insights into the poet’s readings and literary models between 1820 and 1821. Moreover, these texts testify to Shelley’s constant exploration of, and engagement with, poetic conventions and poetic discourse. Viewed in this light, such “poetic flotsam” acquires new importance within Shelley’s canon.

Les Cenci e il don Giovanni: traduzione, (ri)configurazione e “scarto” in una novella Stendhaliana
Creators: name: Perego, Serena
Publisher: name: Altre Modernità
Year: 2020

description: On July 1st, 1837, Stendhal publishes a novella, Les Cenci, in La Revue des Deux Mondes. He deliberately proposes an arbitrary translation of a text from the Roman manuscript of Palazzo Caetani (BNF, Ms Italien 172). Stendhal, who is not new to translation, has already published a novella from the manuscripts, and he progressively evolves into a re-writing of the original text. Nevertheless, in Les Cenci he is still faithful to the original text and the new text shows up the first signals of a paradigmatic change, e.g. the long introduction. Textual occurrences, marks of additions or "flotsams" from the manuscript, point out his poetics of translation. My purpose is to highlight how some of these text "flotsams" are the symptom of a poetics of mystification, which in turn identifies his poetics of enunciation and reception. Eventually, a pragmatic analysis connected to textual deictics, to the enunciative scene and to textual “flotsams” can be useful to understand the whole text construction and the (dis)concordance between the fictional and the real world. Furthermore, it can show up how the text reorganization is the result of a (re)configuration: the “literary myth” of Don Giovanni.

Scrivere il corpo, ferire il testo: la rappresentazione della violenza nel romanzo La sangre de la aurora (2013)
Creators: name: Breusa, Luca
Publisher: name: Altre Modernità
Year: 2020

description: In the 1980 began the internal conflict in Peru between the armed forces, the Peruvian Communist Party-Shining Path (PCP-SL) and the Túpac Amaru Revolutionary Movement (MRTA). The civil war lasted twenty years and it caused nearly 70.000 deaths. The novel Blood of the Dawn (2013) by Claudia Salazar Jiménez was awarded the Las Americas Narrative Prize of Novel in 2014 due to its originality among the abundant literature on this difficult and polemic episode of the recent history of Peru. The fiction is about three women’s lives during the internal conflict, but given that the violence can’t be told by words, Claudia Salazar let women bodies talk and represents the tragedy of “the time of fear” by them. The way their bodies became a symbol of the war and the useless violence turns the novel into a biosemiotics system of representation. In this sense Claudia Salazar’s debut novel exceeds from what is considered the canon of the internal conflict narrative.

Rondini, spille e altre scorie memoriali: strategie del ricordo in Helena Janeczek e Laurent Mauvignier
Creators: name: Suverato, Andrea
Publisher: name: Altre Modernità
Year: 2020

description: The neo-historical novel – literary genre which combines the use of documents, testimony and fiction – offers an ideal case study of what Francesco Orlando, in the early Seventies, called the "formal return of the repressed". Proof of this is the emergence, within the texts, of memorial waste which has been ousted from cultural memory. This article will focus on Des hommes (2009) by Laurent Mauvignier and Le rondini di Montecassino (2010) by Helena Janeczek, two récits de filiation that deal with paternal silence originated by historical trauma. Facing the double censorship of both official and familial discourse, memorial waste turns into a fundamental tool for the writers involved. These marginal sources not only become the main subject of their narratives, but they also directly affect the writing process, as shown by the analysis of narrative models (inner monologue, polyphonic epic), textual spaces and rhetorical devices (blancs, mise en abyme). I will contend that, through different approaches, both texts enable a centripetal movement by which what has been previously marginalized seeks to find its place within the cultural memory.

He towd her soe monny a mad farrant Tele: On flotsam, respellings and the enregisterment of l-vocalisation and /a/+nasal in the Late Modern Lancashire dialect
Creators: name: Ruano-García, Javier
Publisher: name: Altre Modernità
Year: 2020

description: This paper addresses the concept of flotsam in relation to language by examining the non-standard spellings used in a selection of literary representations of the Lancashire dialect written in the Late Modern English period. The analysis is placed within the framework of enregisterment and indexicality, which I explore in combination with recent sociolinguistic approaches to the study of orthography. Attention is paid to two of the frequently occurring features in these speech recreations (l-vocalisation and the rounding of /a/+nasal), arguing that the respellings employed to represent them can be taken as instances of flotsam in that they contribute to highlighting and enregistering linguistic differences.

Esporazione, problema, riciclaggio. Lo scarto come oggetto ed effetto della sua ricerca
Creators: name: Assmann, David-Christopher
Publisher: name: Altre Modernità
Year: 2020

description: The article traces the observation that waste as an object of research is at the same time an effect of its research. It examines three studies on waste: "Rubbish!" by William Rathje and Cullen Murphy, Guido Viale’s "Un mondo usa e getta", and "Das Müll-System" by Volker Grassmuck and Christian Unverzagt. These studies exemplify three types of presenting waste: ‘exploration’, ‘problem’, and ‘recycling’. Considering them as scientific arguments allows us to discuss what is considered to be ‘waste’ by asking questions of representability and at the same time questioning the consequences representation has for the concept of waste.

Posthuman Keats. Poetry as Assemblage
Creators: name: Anselmo, Anna
Publisher: name: Altre Modernità
Year: 2020

description: This article explores the notions of flotsam, jetsam and hybridity in John Keats’s poetry in order to provide a critical reading informed by posthumanist theories, and, more specifically, Donna Haraway’s cyborg. It starts with the metaphor of debris and the linguistic-literary metaphor of texture/textus. It then proceeds to elucidate how Keats deals with flotsam and jetsam in his work. A short overview of the theory of organic unity begins the last section of the article, which focuses on the poet’s penchant for hybrid poetic endeavours and envisions some of his work as a metaphorical manifestation of the cyborg myth.

Jetsam on Flotsam: Notes on Material and other Remnants and Residues
Creators: name: Byers, Thomas
Publisher: name: Altre Modernità
Year: 2020

description: In an attempt to open a conversation on the remnant, this essay proceeds as a collection of notes on the following topics: 1) Definitions of flotsam and jetsam 2) Some famous figures of waste: Defoe, Melville, Twain, myth of Hercules, A.C. Bradley, Trotsky, Walter Benjamin 3) Waste in contemporary fiction and media, with readings of some touchstone passages 4) Found materials and residues as subjects in the visual arts 5) Two final images of flotsam Underlying the discussion of these particulars are three themes based on common reactions to remnants, waste, trash, flotsam and jetsam: devastation, abjection, and bricolage.
