Creating a new research community on detection and classification of acoustic scenes and events: Lessons from the first ten years of DCASE challenges and workshops
Authors: Plumbley Mark , Virtanen Tuomas
Published: February 2023

Research work on automatic speech recognition and automatic music transcription has been around for several decades, supported by dedicated conferences or conference sessions. However, while individual researchers have been working on recognition of more general environmental sounds,
until ten years ago there were no regular workshops or conference sessions where this research, or its researchers, could be found. There was also little available data for researchers to work on or to benchmark their work. In this talk we will outline how a new research community working
on Detection and Classification of Acoustic Scenes and Events (DCASE) has grown over the last ten years, from two challenges on acoustic scene classification and sound event detection with a small workshop poster session, to an annual data challenge with six tasks and a dedicated annual workshop,
attracting hundreds of delegates and strong industry interest. We will also describe how the analysis methods have evolved, from mel frequency cepstral coefficients (MFCCs) or cochelograms classified by support vector machines (SVMs) or hidden Markov models (HMMs), to deep learning methods
such as transfer learning, transformers, and self-supervised learning. We will finish by suggesting some potential future directions for automatic sound recognition and the DCASE community.
Frequency response function statistics of diffuse systems
Authors: Van hoorickx Cédric , Reynders Edwin
Published: February 2023

Vibro-acoustic analysis at high frequencies is challenging due to a large sensitivity to spatial variations and short acoustical wavelengths, rendering deterministic methods expensive. At these frequencies, the wave field is usually assumed diffuse. A realization of a diffuse field
can be obtained considering that the mode shapes of the system are Gaussian random fields, and that its squared eigenfrequency spacings distribution conforms to the Gaussian orthogonal ensemble (GOE) eigenvalue spacings distribution. These diffuse field properties were for example used to
extend statistical energy analysis (SEA) towards energetic variance prediction. However, energetic methods such as SEA lack the propagation of phase information, which means that, e.g., time-domain reconstruction is not possible. In this contribution, instead of total energies, expressions
for the ensemble average and the cross-frequency covariance of frequency response functions are presented. These expressions are obtained from the generalized definition of a diffuse field, treating the eigenfrequencies of a diffuse subsystem as a collection of points randomly located on the
frequency axis, making the analysis amenable to random point process theory. These expressions are numerically validated by comparison with computationally costly detailed models where random wave scatterers are modeled explicitly.
Control and broadening of multiple noise frequencies using an assembly of sub-metamaterials connected by membranes for aircraft noise mitigation.

Published: February 2023

Simultaneously attenuation of multitonal and broadband noise at low frequencies is a challenge for the aerospace, ground transportation and building industries. The technologies proposed in the literature, using layered porous materials with embedded Helmholtz resonators (HR) with a
structured neck, exhibited considerable potential when tuned at tonal, multi-tonal or narrow frequency bands. However, the resonance frequencies due to the structured necks of metamaterial are narrow. Our recent investigations have shown that parallel arrangements of several structured metamaterials
separated by membranes can broaden the resonance frequencies and increase the number of resonance frequencies to be controlled. This paper presents a parallel assembly of four structured sub-metamaterials separated by membranes. Each of these sub-metamaterials is also a serial assembly of
a periodic unit cell (PUC) with a half-neck + cavity + half-neck configuration. The metamaterial is embedded in a layer of glass wool. Coupled fluid-structure numerical calculations in the frequency domain were used to predict the sound absorption coefficient of the metamaterial. The results
obtained show a broadening of the absorption peaks and the appearance of additional frequencies due to the membranes.
Four-element planar arrays focus a point-like source based on the artificial iterative phase conjugated processing
Authors: Li Ting , Zhang Yi , Fu Liufang
Published: February 2023

The artificial iterative phase conjugated processing is an improved algorithm of phase conjugation and has been proven to focus a sharp focal spot using linear array. Because cross-shaped four-element planar array and triangular four-element planar array are widely used in the situation
of little acoustic measuring points , their focal patterns by the artificial iterative phase conjugated processing are discussed in this paper. Theory analysis and numerical simulations gives conclusions. Based on the artificial iterative phase conjugated processing, two arrays focus a smaller
focal spot than that by phase conjugation. As their iterate number increases, focal spot size decreases but the sidelobe amplitude becomes big. Considering the focal spot size and sidelobe interference, the triangular four-element array has a clearer pattern than the cross-shaped one .
Assessment of the Noise Reduction Impact from Application Restrictions on Rail Dampers
Authors: Gramowski Christoph , Donner Roxana
Published: February 2023

In the last decades, rail dampers had become a commonly used rolling noise abatement measure at several mainline and metro networks. Rolling noise reductions outdoor/indoor up to 4/8 dB had been found. While the beginning of damper application was started with multiple test sections,
infrastructure managers had raised installation restrictions from other related technology departments like signaling and communication. This is leading to defined sections where one rail has to remain partially free from dampers or the track has to remain completely free from dampers. These
sections become relevant when the damper application is caused by noise tackling action plans. Therefore, the acoustic impact was assessed by a) laboratory test track analysis (partially free) and b) environmental noise prognosis software (completely free). It is shown, that also for a partially
free rail, a cancellation of the noise reduction can be expected for single 1/3 octave frequencies. This can be relevant for the overall noise emission. The effect from the completely free rail is much larger due to noise increases at several immission points. Railway noise mitigation has
to consider these results or, if possible, the rail damper technology has to be improved to avoid these restricted sections.
Indoor acoustic comfort for ASD people: from independent living to educational environments
Authors: Bettarello Federica , Caniato Marco , Pernigotto Giovanni , Gasparella Andrea
Published: February 2023

Autistic people, their families or caregivers need design processes capable of overcoming the difficulties of everyday life. In 2020, the Centre for Disease Control and Prevention reported that approximately 1 out of 54 children in the U.S. is diagnosed with an Autism Spectrum Disorder.
Buildings are designed to provide a suitable living and learning environment for humans. Indoor comfort is necessary in different types of buildings, such as living, learning, working and healing environments. Good environmental quality is important as it affects health, comfort and productivity,
significantly impacting on psychological and physiological aspects. The traditional reference could not be suitable in environments dedicated to individuals with special needs, since well-being strongly depends on individual differences in perception. It has been demonstrated that impaired
individuals offer diverse responses to indoor environmental stimuli, in comparison with traditional users. Knowing this difference world would permit the realization of more inclusive spaces. Thanks to the first results obtained, a comprehensive representative description of the peculiarities
affecting these individuals' acoustic sensitivity has been obtained. Further developments have been focused on similar acoustic aspects on collective spaces, such as schools, defining which aspects most stress autistic people, as regards building and room acoustics issues.
Main sensitivity drivers in indoor acoustic comfort for autistic individuals
Authors: Caniato Marco , Marzi Arianna , Gasparella Andrea
Published: February 2023

One challenge for railway noise predictions is to characterize noise from various auxiliary equipment, e.g., fans, compressors, transformers. The noise from such sources can be a dominating contribution under low speed operation or stand still. To better handle this problem the EU-project
TRANSIT investigates improved methods for acoustic source characterization. As a starting point it is assumed that an acoustic source is enclosed by a control surface. The surface is sub-divided into smaller areas and each area is assumed to act as an acoustic one-port coupled to all the other
areas. The properties of each area can then be described by its volume flow and internal impedance. The resulting acoustic pressure at a receiving point, can finally be expressed as a product of the source volume flows and a matrix representing the acoustic installation effects ("source+radiation
impedances"). To simplify the method one can assume uncorrelated source surfaces and use an ISO procedure for sound power to determine the volume flows. The acoustic installation effects can be obtained using a monopole point source to measure or calculate the pressure at selected receiving
positions. This simplified method has been validated under controlled laboratory conditions and tested on real equipment on trains.

Authors: Bernfeld David , Mietlicki Christophe , Mietlicki Fanny
Published: February 2023

The developments made by Bruitparif since 2016 around sound source localization technologies applicable to the field of environmental noise resulted in the launch on the market of a patented combined acoustic and imaging sensor called "Medusa". An article of law was voted
in France at the end of 2019 in order to enable the experimentation of noise radars in order to punish drivers causing significant noise nuisances by their behavior. The evaluation process includes track trials, roadsite tests and a final phase with fines. We will describe this national experimentation
and the context in which it takes place. We will then detail the prototype called "Hydre" that we have developed for this purpose, and will present case results showing how it solves the major difficulties of the legal measurement of the pass-by noise of vehicles in real traffic
conditions.
Estimation of Russia's GDP Losses Due to Sanctions Using the Global Vector Autoregression Model
Authors: Zubarev A. V. , Kirillova M. A.
Published: February 2023

Using mathematical and statistical methods, the authors made an attempt to estimate the losses in the domestic economy under the impact of the imposed sanctions. As a measurement tool is proposed a global vector autoregression model. In this model, the dynamics of GDP is considered as the main performance characteristic, and the rate of change in foreign trade turnover with key partners is used as the key prerequisites for the forecast. The use of this model building scheme is explained by the fact that the economic sanctions imposed on Russia have a negative impact on domestic macroeconomic indicators, and this happens through a variety of channels, key ones being the restriction of external demand and supply, leading to a decrease in trade turnover with the main trading partners, and change in oil revenues. This approach takes into account the relationship between the economies of different countries and their dependence on global markets. To obtain quantitative estimates, conditional forecasts are used as part of scenario analysis.

According to the authors’ approach the losses from economic sanctions are measured by the decrease in the volume of Russia's foreign trade with key foreign trade partners, as well as by the discount for Russian oil compared to its global price. In addition to the forecast estimates, the validity of the approach is proofed with the forecast for the crisis period of 2014–2015 as an example. Based on the analysis of the current situation in foreign trade, Russian GDP in 2022 in the baseline scenario may fall by 5.4%, but with some reorientation of trade a decrease may be around 3.7%.
Penélope e seu kéos na nova Odisseia de Margaret Atwood
Authors: Costa Lorena Lopes da
Published: February 2023

Este trabalho analisa a poesia épica antiga utilizada pela (e na) literatura contemporânea para a constituição de um tradição histórico-ficcional da feminilidade. Tal análise pretende desvendar um caso de recepção e a forma como ele funciona, uma vez que a recepção é um procedimento que cobre vastas possibilidades. Aqui, ela se dá dentro da literatura feminista com foco em Penélope - uma personagem que poderia ser vista enquanto uma alegoria da teoria da recepção como sugerido por Vanda Zajko (2011: 195) –, na releitura da Odisseia, The Penelopiad de Margaret Atwood (2005). Atwood usa uma conhecida história para examinar a avaliação que Penélope faz do próprio comportamento em relação à fama. Desejosa de uma boa reputação, a mulher que espera pacientemente por seu marido parece ainda ter medo de sua voz e de seu kléos.

Moreover, the chi-square test was used to describe the relation of rural women-owned businesses type with an education background. Food security was measured by the expenditure method. All the study sample rural women entrepreneurs were married and had large size family. With the increasing family size, cultivating land size is highly decreasing proportionally. Hence, an annually harvested product from farmland cannot feed for more than two months; the above facts push factors into entrepreneurship activities. Types of businesses owned by the sample population were retail, manufacturing, service render and others which most educated entrepreneurs operating from retail businesses: fruit, used cloths and mini-shop retail and from service render businesses: rural cafeteria, rural alcohol grocery and rural restaurant services, while illiterate entrepreneurs operating from retail businesses: flour, grain, vegetables and coffee and all manufacturing businesses (Brewing borde, baking enjera, brew kinoto, baking bread) and others such as Vegetative plant trade and Livestock Trade. The majority of entrepreneurs started operating mentioned businesses ten years. The Source of the initial capital of the study sample was self-saving and household deposit. While household food expenses in a week mean 195 Birr, businesses contribute 63% of the household total food expenditure in a week. According to food security status, most study sample populations are highly food secure. With look upon problems, lack of market and lack of credit facilities are dominating problems. Because of daily food expenses, working financial capital is not increasing. However, Rural Women Entrepreneurship is profitable and dramatically contributes to household food security.

Examining the degree to which GST is perceived is the study’s major goal. 200 questionnaires were used to perform the main survey, and 153 participants answered them. Utilizing a virtual platform, data were gathered (Monkey survey and Google form). When the assumptions (Hypothesis) were put to the test, the majority of respondents (85.50%) accepted the lower-rate GST (<10%). While several nations around the world have implemented the GST at a lower rate, Government of India has directly implemented at the highest rate (18 –28%), which has had a major long-term impact on the Indian economy (R2=0.93, P = 0.01). The majority of respondents (19.61%) were in favour of VAT, while only (3.27%) were in favour of GST. At the 1% level of significance, it was concluded that none of the assertions were related to either GST or VAT (Z= 4.49, P=0.001). Both manufacturers and consumers will be hamper if the price of the goods and services tax is continually raised.

Sobre el perfil físico del guerrero mexica. Una aproximación osteobiográfica
Authors: Serrano Sánchez Carlos
Published: February 2023

La construcción del Cemanáhuac implicó una política expansionista del Estado mexica, de acuerdo con el pensamiento cosmogónico que condujo su desarrollo histórico. La sociedad mexica estuvo organizada en función de su eficiencia militar; tanto los jóvenes de la esfera noble, que acudían al calmécac, como los de estratos bajos, que se incorporaban al telpochcalli, recibían una educación que miraba al desarrollo de las habilidades requeridas para la acción bélica. Las fuentes mencionan el entrenamiento al que eran sujetos para fortalecer su carácter y obtener las habilidades propias de un guerrero.
Los estudios realizados en restos esqueléticos mexicas muestran condiciones físicas de desarrollo satisfactorias y un buen estado de salud. El perfil físico de un guerrero mexica se puede ejemplificar, desde los actuales estudios de osteología antropológica, con un caso descrito en detalle, en el cual se registraron rasgos de gran fortaleza física y huellas de traumatismos por confrontaciones violentas, quizás relacionadas a actividades bélicas. Estas observaciones tienen que ver con la capacidad física desplegada por el pueblo mexica, en particular de los guerreros, al momento del asedio hispano a su capital; defensa férrea que no logró superar las adversidades del contexto sociopolítico que marcó este suceso.
Los tarascos rivales de Tenochtitlan. Una década en la ruta conquistadora de Michoacán, el norte y el noroccidente de Mesoamérica
Authors: Paredes Martínez Carlos
Published: February 2023

En la última etapa de la época prehispánica, tarascos y mexicas estaban en guerra respondiendo a impulsos expansionistas y conquistadores en el occidente de Mesoamérica. Al arribo de los españoles a las costas de Veracruz en 1519, Moctezuma II propuso a los tarascos una alianza con ellos, que permitiera enfrentar a los invasores y expulsarlos de tierra firme. Esta propuesta es rechazada por los tarascos, por razón de la desconfianza y animadversión hacia el poder mexica que prevalecía hasta ese momento. De esta manera mexicas y tarascos viven su propia conquista, Tenochtitlán mediante el violentoenfrentamiento de los ejércitos y sus aliados en 1521, mientras que Tzintzuntzan y su poder político uacúsecha, por medio de la negociación, el engaño y finalmente la rendición. En este trabajo se analizan estos acontecimientos, así como el llamado proceso de conquista de Michoacán propuesto por Benedict Warren, sucedido en la década de mil quinientos veinte. En algunos aspectos estamos ante una historia paralela que llevaron a la conquista de Tenochtitlán y en otros temas, asistimos a las formas tempranas de la imposición del dominio español. De esta manera se muestran los insaciables apetitos por parte de losespañoles por los metales preciosos y la búsqueda de nuevas tierras, reales e imaginarias, al noroccidente y al norte de Mesoamérica.

Authors: Derevianko I.O. , Turchynova N.Р.
Published: February 2023

The results of three annual studies on the studied reaction of spring barley plants to the level of moisture supply during the growing season have already been covered. In order to study the diversity of collection samples of spring barley in response to drought, we used an index approach, which is widely used by foreign scientists. With the help of the seven most common of them. These are: drought susceptibility index, tolerance index, average yield, yield stability index, yield index, stress tolerance index and geometric mean yield. 37 samples of spring barley from the collection have already been evaluated to establish the selection value of these samples for drought resistance. According to the results of the evaluation of the collection of spring barley cuttings according to dry resistance indices, it has already been established that the samples: Vodohrai (UKR), Nutans 108 (RUS); Nutans 553 (RUS), Nutans 642 (RUS), Omskyi 90 (RUS), Orenburhskyi 35 (RUS), Karabalykskyi 43 (KAZ); Nutans 89 (KGZ) had a higher level of dry resistance compared to other samples from the collection. These samples can be involved in breeding programs to create competitive varieties of spring barley, which will be adapted to the conditions of the eastern part of the ForestSteppe of Ukraine.

Keywords: spring barley, selection, dry resistance, indices of dry resistance, tolerance, stress, adaptation.

Authors: Kuchiji Hiroyuki , Masumoto Naoki , Baba Akiyoshi
Published: February 2023

In this study, we developed an acoustic sensor with a structure in which a piezoelectric cantilever array is covered with an organic film. For this, we used AlN and polyurethane as the piezoelectric material and organic film, respectively. The results suggested that the sensitivity in the low-frequency region improved, and the resonance frequency increased. We investigated the resonance frequency based on a simulation and verified that it matched the measured value. Further, we created a broadband acoustic sensor by covering the space between the cantilevers with an organic film.

Published: February 2023

A transparent, optically observable microfluidic device for microwave-induced chemical reactions using 24.125 GHz ISM band incorporating was developed. The microfluidic channels can pass through gaps in the post-wall waveguide. The post-wall waveguide allows microwave irradiation to be applied to designed area of the microfluidic channel. In this study, Polydimethylsiloxane (PDMS), commonly used in microfluidic devices, was used as the microwave waveguide material. A glass plate sputtered with indium tin oxide was used to shield microwave leakage to the top and bottom. 4 W of microwave input power was used to heat ethylene glycol, which is used as a solvent in chemical synthesis, in the channels of the fabricated device, and a temperature rise to 100 °C was observed in 70 s. We believe that the use of PDMS as a waveguide material will facilitate observation during microwave irradiation using optics and combination with other microreactors.
Crystalline phase control of BiVO4 thin films using RF sputtering

Published: February 2023

A selective fabrication method for monoclinic-scheelite (m-s) BiVO4 and tetragonal-zircon (t-z) BiVO4 thin films using radio fRequency (RF) sputtering from a single target was developed. The kinetic energy of the sputtered atoms was controlled by varying the sputtering power to obtain BiVO4 films with m-s and t-z crystalline phases. Although the band gap of the t-z BiVO4 phase (3.0 eV) was larger than that of m-s BiVO4 (2.5 eV), the deposited t-z BiVO4 films showed a comparable photocurrent density (1.5 mA cm−2) at 1.23 V versus the reversible hydrogen electrode (400 W Xe lamp). This was mainly because of the reduced sputtering damage in the t-z BiVO4 crystal, which originated from the low sputtering power as well as the deep valence-band position in t-z BiVO4 that enabled the efficient utilization of the photocarriers. This work provides insights into crystalline phase control using the particle kinetic energy in sputtering.

The propagation and resonance properties of longitudinal leaky surface acoustic waves on structures consisting of a LiTaO3 (LT) thin plate bonded to a quartz (Qz) similar-material bonded structure were investigated theoretically. It was found by surface acoustic wave (SAW) propagation analysis that a small attenuation can be obtained by combining an LT thin plate and a Qz similar-material bonded structure with appropriate Euler angles. Furthermore, regarding SAW resonance analysis, resonances with admittance ratios exceeding 50 dB and Q factors exceeding 1000 were obtained in the LT/Qz/Qz bonded structure. Such a small propagation loss and high Q can be obtained with a larger LT plate thickness than in the case of the LT/Qz bonded structure.
Effects from imaging parameters of sub-aperture averaging in minimum variance adaptive beamforming using outputs of delay-and-sum beamformer
Authors: Nagaoka Ryo , Omura Masaaki , Hasegawa Hideyuki
Published: February 2023

We proposed a reduction method of the computational cost for the minimum variance (MV) adaptive beamforming. In the method, a receiving aperture was divided into several sub-apertures, and outputs of the delay-and-sum (DAS) beamformer in the divided sub-apertures were used as inputs of the MV beamformer. Lateral resolutions were evaluated under different division numbers, distances between sub-apertures, and their overlapping ratios in sub-aperture averaging. As a result, the resolution was improved by 44.3% compared with the DAS method at a distance between sub-apertures of 1 mm (5 elements) when dividing the aperture by 5 in sub-aperture averaging.

In this work, the effects of post-deposition annealing (PDA) on Al2O3/GeO
x
/(111) and (100) n-Ge structures are experimentally studied with changing annealing temperatures from 300 °C to 650 °C in a vacuum, N2 and O2 atmosphere in order to clarify the stability of the MOS interface properties under high-temperature annealing. A decrease in D
it and an increase in the oxide capacitance with increasing PDA temperature is observed up to 500 ∼ 600 °C, depending on the annealing atmosphere and surface orientation. The minimum D
it of ∼3 × 1011 eV−1cm−2 is achieved for (111) Ge after PDA at 550 °C and 600 °C in N2/O2 or vacuum. This trend is similar to the (100) MOS interfaces and a similar amount of minimum D
it is obtained. These results suggest that the present Al2O3/GeO
x
/Ge interfaces are suitable for the formation of the Ge-On-insulator (GOI) back interfaces by the wafer bonding process in the Smart-cut, where high-temperature annealing is indispensable.

Authors: Cesaroni Ilaria , Marozzi Gioele
Published: February 2023

Il contributo intende offrire una presentazione di possibili modalità con cui applicare i principi della data visualization agli studi umanistici per realizzare una mappatura digitale delle lettere spedite da Monaldo e Giacomo Leopardi. Uno sguardo particolare viene poi riservato, rispettivamente, alla costituzione della Biblioteca di Casa Leopardi e al carteggio con Antonio Fortunato Stella.
L’eterno conflitto città-campagna. Luoghi reali e paesaggi idealizzati nella poesia
di Tito Strozzi
Authors: Leidi Giulia
Published: February 2023

Il contributo propone l’analisi di un tema universalmente diffuso, la dicotomia città-campagna, nella produzione poetica di Tito Strozzi. Si esamina in prospettiva diacronica come la raffigurazione del topos classico, attualizzato attraverso l’uso di toponimi, evolva con la maturità del poeta e i mutamenti storici, da un iniziale contesto elegiaco e idealizzato ad un quadro drammaticamente reale.
La «carta delle pianure». Una mappatura della letteratura emiliana a partire dai luoghi e dai racconti di Gianni Celati
Authors: Monina Cecilia
Published: February 2023

Gli «alfabeti visivi» di Luigi Ghirri e le prose di Gianni Celati hanno contribuito a far entrare l’Emilia nell’immaginario letterario, aprendo una pista per gli autori delle generazioni successive. Si cercherà qui di tracciare un itinerario geo-letterario partire dalla «carta delle pianure» celatiana, arrivando a ricostruire una mappa della letteratura emiliana, definendone forme e temi.
La mappa come teoria: sguardo, volo e narrazione in Daniele Del Giudice
Authors: Baratta Aldo
Published: February 2023

La teoria viene sempre più frequentemente declinata secondo una prospettiva cartografica, a partire da alcune espressioni che Lukács adopera in Theorie des Romans fino ad approdare alla critical literary cartography fiorita negli ultimi decenni. Quest’intervento intende indagare la presenza della mappa in quanto dispositivo teorico e narrativo all’interno dell’opera di Daniele Del Giudice.
Forme digitali della «mappa» in letteratura italiana contemporanea
Authors: Magoni Davide
Published: February 2023

La conoscibilità del territorio non dipende dalla performatività degli strumenti con cui lo spazio viene riprodotto. Nel presente articolo si commentano alcuni romanzi italiani contemporanei che mostrano quanto la cartografia digitale, malgrado proponga riproduzioni accurate dello spazio, possa indurre interpretazioni stranianti della realtà in cui si vive.
Correzioni e variazioni autografe nel manoscritto del Paradiso degli Alberti: una questione di stile?
Authors: Mondani Paola
Published: February 2023

Il contributo prende in esame alcuni aspetti stilistici e ritmico-retorici nell’autografo del Paradiso degli Alberti: le molte cancellature, riscritture e integrazioni sono traccia della volontà stilistica dell’autore, il quale sembra operare essenzialmente in tre direzioni: la “superlativizzazione” (aggiunta di aggettivi al grado superlativo), la “poetizzazione” della prosa (inserzione di versi, cadenze ritmiche e figure retoriche) e gli emendamenti lessicali (che garantiscono il rispetto della variatio).
L’alchimia della parola. Appunti preliminari a un sondaggio linguistico nel Driadeo di Luca Pulci
Authors: Bardi Rebecca
Published: February 2023

L’intervento propone un primo confronto, per ora limitato a lemmi selezionati, tra il Vocabulista di Luigi Pulci e il Driadeo del fratello Luca. S’intende nello specifico stabilire in che modo la grande ricchezza lessicale della lingua di Luigi possa essere stata di esempio anche per Luca Pulci nella composizione della sua prima opera poetica negli anni dell’esilio in Mugello (1464-65).
Mappare il cantiere delle Historiae Venetae del Bembo. Il ms. marciano cl. x 256 (=3134)
Authors: Facchin Carlo
Published: February 2023

Il lavoro descrive il ms. autografo del Bembo marciano cl. X 256 (3134). in particolare, analizza l’aspetto del riordino delle carte. Infatti, la presenza della numerazione antica farebbe pensare a un riordino delle carte, che sono tra loro molto disomogenee, da parte dell’autore per orientarsi all’interno della sua opera. In realtà chi ha riorganizzato il codice sembrerebbe essere il Morelli.
Marino all’occhiale. La lingua dell’Adone tra «chiarezza, purità, convenienza, ornamento, diversità» secondo Tommaso Stigliani
Authors: Marincola Giampiero Giuseppe
Published: February 2023

L’articolo si propone di individuare gli aspetti più significativi della critica condotta nell’Occhiale (1627) da Tommaso Stigliani contro il lessico dell’Adone di Giovan Battista Marino (1623). Le note di Stigliani, pur definendo in negativo le regole della lingua del poema eroico, contribuiscono tuttavia a mettere in luce parte della novità e della ricchezza degli elementi lessicali, tradizionali e non, del poema mariniano.
«Diligenza» ed «esattezza» della correzione. La punteggiatura nell’evoluzione e nella trasmissione dei testi leopardiani a partire dall’Epistolario
Authors: Rosato Morena
Published: February 2023

La presente proposta mira a ricostruire il metodo compositivo leopardiano nel processo di creazione e di trasmissione del testo attraverso le correzioni riguardanti la punteggiatura. Si cerca infatti di illustrare il modus operandi di Leopardi a partire dai suoi interventi sulla punteggiatura e dalle raccomandazioni contenute in una delle opere da cui più chiaramente si può cogliere l’attitudine di Leopardi verso la chiarezza e l’accuratezza stilistica: l’Epistolario.
Le provvisorie mète. Lo «Spirito ribelle» del Lucini naturalista
Authors: Lovari Gianmarco
Published: February 2023

Il contributo intende mettere in evidenza le cospicue modificazioni subìte dalla prima prova letteraria di Gian Pietro Lucini dal titolo Spirito ribelle, rilevando le differenze fra la sua originaria struttura naturalista e la seconda stesura. Tale passaggio riesce a farsi metafora di un nuovo modo di concepire la prassi letteraria, oramai distante da qualsiasi forma di realismo in direzione propriamente novecentesca.

Published: February 2023

Il dialogo fra Carlo Facchin e Michele Bordoni riporta in forma scritta, con sostanziali rimodulazioni e ricalibrature, le principali questioni sollevate in sede di convegno: quali sono le relazioni fra la poesia (di Bordoni) e il concetto di mappa? che ruolo ha il paesaggio cittadino (in particolare quello veneto) nelle poesie di Bordoni? esiste ancora una poesia bucolica nella contemporaneità?
Fare del proprio guscio un cielo. Gli spazi dell’inermità nella scrittura di Antonella Anedda
Authors: Bello Minciacchi Cecilia
Published: February 2023

Il contributo analizza luoghi puntuali e immagini d’inermità ricorrenti nell’opera di Antonella Anedda, rivelando come oggetti miti e spazi limitati e privati diventino nuclei da cui irradiare lo sguardo fuori da sé, gusci di cui fare «un cielo». Nella sua poetica, la contrainte dello spazio minuto, della «mandorla», ove trovare vasti orizzonti proiettati all’esterno è scelta di trasparenza.
