Face models based on a guided PCA of motion-capture data: speaker dependent variability in /s/-/R/ contrast production
Creators: name: Maeda, Shinji
Publisher: name: ZAS Papers in Linguistics
Year: 2005

description: We measure face deformations during speech production using a motion capture system, which provides 3D coordinate data of about 60 markers glued on the speaker's face. An arbitrary orthogonal factor analysis followed by a principal component analysis (together called a guided PCA) of the data has showed that the first 6 factors explain about 90% of the variance, for each of our 3 speakers. The 6 derived factors, therefore, allow us to efficiently analyze or to reconstruct with a reasonable accuracy the observed face deformations. Since these factors can be interpreted in articulatory terms, they can reveal underlying articulatory organizations. The comparison of lip gestures in terms of data derived factors suggests that these speakers differently maneuver the lips to achieve contrast between /s/ and /R/. Such inter-speaker variability can occur because the acoustic contrast of these fricatives is shaped not only by the lip tube but also by cavities inside the mouth such as the sublingual cavity. In other words, these tube and cavity can acoustically compensate each other to produce their required acoustic properties.

description: Per un docente di italiano L2 può essere molto utile conoscere il background sociolinguistico dei propri apprendenti, al fine di comprenderne i comportamenti linguistici e di selezionare alcune forme pragmalinguistiche e varietà oggetto di insegnamento. Partendo da questo presupposto, la presente ricerca intende delineare in maniera esplorativa il profilo sociolinguistico dell’apprendente srilankese di italiano L2 a Napoli. I dati raccolti attraverso la somministrazione di un questionario sociolinguistico a 40 srilankesi adulti (di cui 19 donne) hanno permesso di ricavare informazioni sugli usi linguistici in Sri Lanka, di osservare le trasformazioni nel repertorio linguistico post-immigratorio di tali apprendenti e di ipotizzare il ruolo dei diversi codici di cui esso si compone, con uno sguardo anche al dialetto napoletano. Sri Lankan learners of L2 Italian in Naples: notes for a sociolinguistic profile Gathering information about the sociolinguistic background of learners could be very helpful for an L2 Italian teacher, in order to understand linguistic behaviors and select pragma-linguistic forms and L2 varieties to focus on. Starting from this assumption, this study aims to outline a possible sociolinguistic profile of Sri Lankan learners of L2 Italian in Naples. Data was collected through the administration of a sociolinguistic questionnaire to 40 adult Sri Lankan immigrants (of which 19 were female). The learners’ linguistic repertoires before migration to Italy was described and its restructuring after migration was observed, trying to explain the relationship between the different languages and with a specific focus on the Neapolitan dialect.

description: A visual articulatory model based on static MRI-data of isolated sounds and its application in therapy of speech disorders is described. The model is capable of generating video sequences of articulatory movements or still images of articulatory target positions within the midsagittal plane. On the basis of this model (1) a visual stimulation technique for the therapy of patients suffering from speech disorders and (2) a rating test for visual recognition of speech movements was developed. Results indicate that patients produce recognition rates above level of chance already without any training and that patients are capable of increasing their recognition rate over the time course of therapy significantly.

Learning to control an articulatory synthesizer by imitating real speech
Creators: name: Howard, Ian S.
name: Huckvale, Mark A.
Publisher: name: ZAS Papers in Linguistics
Year: 2005

description: The goal of our current project is to build a system that can learn to imitate a version of a spoken utterance using an articulatory speech synthesiser. The approach is informed and inspired by knowledge of early infant speech development. Thus we expect our system to reproduce and exploit the utility of infant behaviours such as listening, vocal play, babbling and word imitation. We expect our system to develop a relationship between the sound-making capabilities of its vocal tract and the phonetic/phonological structure of imitated utterances. At the heart of our approach is the learning of an inverse model that relates acoustic and motor representations of speech. The acoustic to auditory mappings uses an auditory filter bank and a self-organizing phase of learning. The inverse model from auditory to vocal tract control parameters is estimated using a babbling phase, in which the vocal tract is essentially driven in a random manner, much like the babbling phase of speech acquisition in infants. The complete system can be used to imitate simple utterances through a direct mapping from sound to control parameters. Our initial results show that this procedure works well for sounds generated by its own voice. Further work is needed to build a phonological control level and achieve better performance with real speech.

description: To date, most efforts to demonstrate quantum nonlocality have concentrated on systems of two (or very few) particles. It is however difficult in many experiments to address individual particles, making it hard to highlight the presence of nonlocality. We show how a natural setup with no access to individual particles allows one to violate the CHSH inequality with many pairs, including in our analysis effects of noise and losses. We discuss the case of distinguishable and indistinguishable particles. Finally, a comparison of these two situations provides new insight into the complex relation between entanglement and nonlocality.

description: Using a traveling-wave OPA with two orthogonally oriented type-I BBO crystals pumped by picosecond pulses, we generate vertically and horizontally polarized squeezed vacuum states within a broad range of wavelengths and angles. Depending on the phase between these states, fluctuations in one or another Stokes parameters are suppressed below the shot-noise limit. Due to the large number of photon pairs produced, no local oscillator is required, and 3dB squeezing is observed by means of direct detection.

description: We present a 9 deg^2 map of the North American and Pelican Nebulae regions obtained in all four IRAC channels with the Spitzer Space Telescope. The resulting photometry is merged with that at JHKs from 2MASS and a more spatially limited $BVI$ survey from previous ground-based work. We use a mixture of color- color diagrams to select a minimally contaminated set of more than 1600 objects that we claim are young stellar objects (YSOs) associated with the star forming region. Because our selection technique uses IR excess as a requirement, our sample is strongly biased against inclusion of Class III YSOs. The distribution of IRAC spectral slopes for our YSOs indicates that most of these objects are Class II, with a peak towards steeper spectral slopes but a substantial contribution from a tail of flat spectrum and Class I type objects. By studying the small fraction of the sample that is optically visible, we infer a typical age of a few Myr for the low mass population. The young stars are clustered, with about a third of them located in eight clusters that are located within or near the LDN 935 dark cloud. Half of the YSOs are located in regions with surface densities higher than 1000 YSOs / deg^2. The Class I objects are more clustered than the Class II stars.

Combining analytical and quantum Monte Carlo (QMC) calculations using experimentally realistic parameters, we show that AF correlations can be detected for temperatures above and below the critical temperature for AF ordering. It is demonstrated that spin-resolved noise correlations yield important information about the spin ordering. Finally, we show how to extract the spin correlation length and the related critical exponent of the AF transition from the noise.

description: We report the discovery of a supernova (SN) with the highest apparent energy output to date and conclude that it represents an extreme example of the Type IIn subclass. The SN, which was discovered behind the Large Magellanic Cloud at z = 0.289 by the SuperMACHO microlensing survey, peaked at M_R = -21.5 mag and only declined by 2.9 mag over 4.7 years after the peak. Over this period, SN 2003ma had an integrated bolometric luminosity of 4 x 10^51 ergs, more than any other SN to date. The radiated energy is close to the limit allowed by conventional core-collapse explosions. Optical spectra reveal that SN 2003ma has persistent single-peaked intermediate-width hydrogen lines, a signature of interaction between the SN and a dense circumstellar medium. The light curves show further evidence for circumstellar interaction, including a long plateau with a shape very similar to the classic SN IIn 1988Z -- however, SN 2003ma is ten times more luminous at all epochs. The fast velocity measured for the intermediate-width H_alpha component (~6000 km/s) points towards an extremely energetic explosion (> 10^52 ergs), which imparts a faster blast-wave speed to the post-shock material and a higher luminosity from the interaction than is observed in typical SNe IIn. Mid-infrared observations of SN 2003ma suggest an infrared light echo is produced by normal interstellar dust at a distance ~0.5 pc from the SN.

Acoustic, kinematic and aerodynamic aspects of wordinitial and word-final vowels in pre-boundary context in French
Creators: name: Gendrot, Cédric
Publisher: name: ZAS Papers in Linguistics
Year: 2005

description: Four speakers repeated 8 times 15 sentences containing 'pVp' syllables (V being /a/, /i/ and /u/). The 'pVp' syllables were located in final, penultimate and antepenultimate position relatively to the Intonational Phrase (IP) boundary. They were embedded in lexical words of 1-3 syllables and were either word-initial or word-final. Results show that the closer the vowel in word-final position is to the IP boundary, the longer the duration and the higher the fundamental frequency of the vowel; it is also characterised by larger lip opening gestures. The potential reduction or coarticulation of vowels in wordinitial position compared to their counterparts in word-final position is discussed.

Diapycnal advection by nonlinear processes in the ocean
Creators: name: Klocker, Andreas
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Physical oceanography

description: The nonlinear nature of the equation of state of seawater leads to numerous interesting processes in the ocean. Two of the more well-known processes caused by nonlinearities in the equation of state are cabbeling and thermobaricity. Other nonlinearities lead to difficulties in analyzing water-mass transformation on continuous ‘density’ surfaces due to the ill-defined nature of neutral surfaces. This ill-defined nature of neutral surfaces describes the problem of not being able to globally connect neutral tangent planes, i.e. planes which describe the local mixing direction of fluid particles in the absence of diapycnal mixing, to form a well-defined surface in three-dimensional space. All these processes have been known to exist for quite some time but their impact on ocean circulation and its analysis remains elusive. In this work an algorithm is introduced which improves the description of existing density surfaces to ensure that the resulting surfaces are as close to approximating neutral tangent planes as possible. Because of the remaining slope errors between these continuous ‘density’ surfaces and the neutral tangent planes, even in the absence of diapycnal mixing processes fluid trajectories penetrate through any continuous ‘density’ surfaces. This leads to a fictitious diapycnal diffusivity and an extra physical mechanism that achieves mean vertical advection in the ocean through any continuous ‘density’ surface. Using these accurate density surfaces, the effects of cabbeling, thermobaricity and the diapycnal advection due to the ill-defined nature of neutral surfaces are quantified. It is shown that these processes cause a significant downward diapycnal transport on the order of 6 Sv, concentrated in the Southern Ocean. This additional production of dense water has implications on the ocean’s energetics which is discussed in this work. A new form of vertical advection, similar to the diapycnal advection due to the ill-defined nature of neutral surfaces but caused by temporal changes of the ocean’s hydrography instead of spatial changes, is also introduced here. Another consequence of the ill-defined nature of neutral surface is the non-existence of a geostrophic streamfunction. New approximate expressions for the geostrophic streamfunction are also developed and are shown to be significantly more accurate than previously available expressions. All the algorithms described and the used to quantify the diapycnal velocities caused by nonlinearities in the equation of state are implemented in Matlab. This code including a user manual is part of this work.
Anatomical structures involved in non-human vocalization

Publisher: name: ZAS Papers in Linguistics
Year: 2005

description: In order to understand the functional morphology of the human voice producing system, we are in need of data on the vocal tract anatomy of other mammalian species. The larynges and vocal tracts of four species of Artiodactyla were investigated in combination with acoustic analyses of their respective calls. Different evolutionary specializations of laryngeal characters may lead to similar effects on sound production. In the investigated species, such specializations are: the elongation and mass increase of the vocal folds, the volume increase of the laryngeal vestibulum by an enlarged thyroid cartilage and the formation of laryngeal ventricles. Both the elongation of the vocal folds and the increase of the oscillating masses lower the fundamental frequency. The influence of an increased volume of the laryngeal vestibulum on sound production remains unclear. The anatomical and acoustic results are presented together with considerations about the habitats and the mating systems of the respective species.

Merging methods of speech visualization
Creators: name: Fagel, Sascha
Publisher: name: ZAS Papers in Linguistics
Year: 2005

description: The author presents MASSY, the MODULAR AUDIOVISUAL SPEECH SYNTHESIZER. The system combines two approaches of visual speech synthesis. Two control models are implemented: a (data based) di-viseme model and a (rule based) dominance model where both produce control commands in a parameterized articulation space. Analogously two visualization methods are implemented: an image based (video-realistic) face model and a 3D synthetic head. Both face models can be driven by both the data based and the rule based articulation model. The high-level visual speech synthesis generates a sequence of control commands for the visible articulation. For every virtual articulator (articulation parameter) the 3D synthetic face model defines a set of displacement vectors for the vertices of the 3D objects of the head. The vertices of the 3D synthetic head then are moved by linear combinations of these displacement vectors to visualize articulation movements. For the image based video synthesis a single reference image is deformed to fit the facial properties derived from the control commands. Facial feature points and facial displacements have to be defined for the reference image. The algorithm can also use an image database with appropriately annotated facial properties. An example database was built automatically from video recordings. Both the 3D synthetic face and the image based face generate visual speech that is capable to increase the intelligibility of audible speech. Other well known image based audiovisual speech synthesis systems like MIKETALK and VIDEO REWRITE concatenate pre-recorded single images or video sequences, respectively. Parametric talking heads like BALDI control a parametric face with a parametric articulation model. The presented system demonstrates the compatibility of parametric and data based visual speech synthesis approaches.

description: By combining the DiPerna and Lions techniques for the nonrelativistic Boltzmann equation and the Dudyński and Ekiel-Jeżewska device of the causality of the relativistic Boltzmann equation, it is shown that there exists a global mild solution to the Cauchy problem for the relativistic Boltzmann equation with the assumptions of the relativistic scattering cross section including some relativistic hard interactions and the initial data satisfying finite mass, energy and entropy. This is in fact an extension of the result of Dudyński and Ekiel-Jeżewska to the case of the relativistic Boltzmann equation with hard interactions.

description: We used the Extended Submillimeter Array (eSMA) in its most extended configuration to investigate the innermost (within a radius of 290 R* from the star) circumstellar envelope (CSE) of IRC+10216. We imaged the CSE using HCN and other molecular lines with a beam size of 0."22 x 0."46, deeply into the very inner edge (15 R*) of the envelope where the expansion velocity is only 3 km/s. The excitation mechanism of hot HCN and KCl maser lines is discussed. HCN maser components are spatially resolved for the first time on an astronomical object. We identified two discrete regions in the envelope: a region with a radius of . 15 R*, where molecular species have just formed and the gas has begun to be accelerated (region I) and a shell region (region II) with a radius of 23 R* and a thickness of 15 R*, whose expansion velocity has reached up to 13 km/s, nearly the terminal velocity of 15 km/s. The Si$^{34}$S line detected in region I shows a large expansion velocity of 16 km/s due to strong wing components, indicating that the emission may arise from a shock region in the innermost envelope. In region II, the P.A. of the most copious mass loss direction was found to be 120 +/- 10 degrees, which may correspond to the equatorial direction of the star. Region II contains a torus-like feature. These two regions may have emerged due to significant differences in the size distributions of the dust particles in the two regions.

description: It has been shown that visual cues play a crucial role in the perception of vowels and consonants. Conflicting consonantal stimuli presented in the visual and auditory modalities can even result in the emergence of a third perceptual unit (McGurk effect). From a developmental point of view, several studies report that newborns can associate the image of a face uttering a given vowel to the auditory signal corresponding to this vowel; visual cues are thus used by the newborns. Despite the large number of studies carried out with adult speakers and newborns, very little work has been conducted with preschool-aged children. This contribution is aimed at describing the use of auditory and visual cues by 4 and 5-year-old French Canadian speakers, compared to adult speakers, in the identification of voiced consonants. Audiovisual recordings of a French Canadian speaker uttering the sequences [aba], [ada], [aga], [ava], [ibi], [idi], [igi], [ivi] have been carried out. The acoustic and visual signals have been extracted and analysed so that conflicting and non-conflicting stimuli, between the two modalities, were obtained. The resulting stimuli were presented as a perceptual test to eight 4 and 5-year-old French Canadian speakers and ten adults in three conditions: visual-only, auditory-only, and audiovisual. Results show that, even though the visual cues have a significant effect on the identification of the stimuli for adults and children, children are less sensitive to visual cues in the audiovisual condition. Such results shed light on the role of multimodal perception in the emergence and the refinement of the phonological system in children.

description: Multisite covalent modification of proteins is omnipresent in eukaryotic cells. A well-known example is the mitogen-activated protein kinase (MAPK) cascade, where in each layer of the cascade a protein is phosphorylated at two sites. It has long been known that the response of a MAPK pathway strongly depends on whether the enzymes that modify the protein act processively or distributively: distributive mechanism, in which the enzyme molecules have to release the substrate molecules in between the modification of the two sites, can generate an ultrasensitive response and lead to hysteresis and bistability. We study by Green's Function Reaction Dynamics, a stochastic scheme that makes it possible to simulate biochemical networks at the particle level and in time and space, a dual phosphorylation cycle in which the enzymes act according to a distributive mechanism. We find that the response of this network can differ dramatically from that predicted by a mean-field analysis based on the chemical rate equations. In particular, rapid rebindings of the enzyme molecules to the substrate molecules after modification of the first site can markedly speed up the response, and lead to loss of ultrasensitivity and bistability. In essence, rapid enzyme-substrate rebindings can turn a distributive mechanism into a processive mechanism. We argue that slow ADP release by the enzymes can protect the system against these rapid rebindings, thus enabling ultrasensitivity and bistability.
South-east Australian Indigenous space and its cosmological origin
Creators: name: Power, Jacqueline
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Architectural history, theory and criticism

description: Purpose: The purpose of this thesis is to investigate Australian Indigenous spatial ordering. The central question guiding the research is: how does south-east Australian Indigenous spatial ordering differ from the European concept of spatial ordering? The hypothesis is that south-east Australian Indigenous occupation of space can be understood as interiority; in addition, it is also hypothesised that colonising western Europeans failed to understand this occupation and as a result, sought to impose western European spatial ordering in its place. The thesis presents a new narrative that is specifically associated with the discipline of interior architecture. Methodology: The overall research framework adopted in the thesis is a ‘spatial approach.’ An interpretive-historical research methodology is operating in a majority of the thesis chapters, bar one (Chapter 8), which diverges from this approach and adopts an ethnographic-type research methodology. A number of research methods have been utilised in order to gather and analyse the empirical material contained in this thesis. Results: Empirical material has been gathered and considered in relation to, but not only, the Sky Dome, palawa buildings, the site of Wybalenna, and Ring Trees. The aforesaid examples contribute to the thesis by allowing a questioning of the following: how cosmology lays the foundation for physical spatial ordering, how building types play a role in defining spatial ordering, the resistance of the palawa peoples to western European spatial ordering, and how Ring Trees in Wadi Wadi Country illustrate a spatial organising principle. Conclusions: The thesis concludes that western European spatial ordering, concerned with an inside and outside, finds expression differently in south-east Australian Indigenous buildings. These buildings are argued to operate as artefacts within spatial divisions enacted at a much larger scale defined by cosmology and inhabitation of the cultural landscape. The contribution that this thesis makes is to enable the western European spatial ordering model to transform and accommodate variations of its expression, as well as to contribute more broadly to the dialogue regarding Australian Indigenous buildings and space.

description: In this paper, Estimation of Distribution Algorithm (EDA) is used for Zone Routing Protocol (ZRP) in Mobile Ad-hoc Network instead of Genetic Algorithm (GA). It is an evolutionary approach, it is used when the network size grows and the search space increases. When the destination is outside the zone, EDA is applied to find the route with minimum cost and time. Finally, the implementation of proposed method is compared with Genetic ZRP, i.e., GZRP and the result demonstrates better performance for the proposed method. Since the method provides a set of paths to the destination, it results in load balance to the network. As both EDA and GA use random search method to reach the optimal point, the searching cost reduced significantly, especially when the number of data is large.

description: This special issue of the ZAS Papers in Linguistics contains a collection of papers of the French-German Thematic Summerschool on "Cognitive and physical models of speech production, and speech perception and of their interaction". Organized by Susanne Fuchs (ZAS Berlin), Jonathan Harrington (IPdS Kiel), Pascal Perrier (ICP Grenoble) and Bernd Pompino-Marschall (HUB and ZAS Berlin) and funded by the German-French University in Saarbrücken this summerschool was held from September 19th till 24th 2004 at the coast of the Baltic Sea at the Heimvolkshochschule Lubmin (Germany) with 45 participants from Germany, France, Great Britain, Italy and Canada. The scientific program of this summerschool that is reprinted at the end of this volume included 11 key-note presentations by invited speakers, 21 oral presentations and a poster session (8 presentations). The names and addresses of all participants are also given in the back matter of this volume. All participants was offered the opportunity to publish an extended version of their presentation in the ZAS Papers in Linguistics. All submitted papers underwent a review and an editing procedure by external experts and the organizers of the summerschool. As it is the case in a summerschool, papers present either works in progress, or works at a more advanced stage, or tutorials. They are ordered alphabetically by their first author's name, fortunately resulting in the fact that this special issue starts out with the paper that won the award as best pre-doctoral presentation, i.e. Sophie Dupont, Jérôme Aubin and Lucie Ménard with "A study of the McGurk effect in 4 and 5-year-old French Canadian children".

description: L’articolo si propone di descrivere e valutare un’attività didattica informatizzata volta allo sviluppo della competenza ortografica, qui proposta a un gruppo di studenti polacchi del primo anno di italianistica. La struttura bersaglio considerata è la variabile pronuncia della lettera a seconda del contesto grafico. L’esercizio chiedeva di esprimere le regole ortografiche corrispondenti in termini di espressioni regolari, uno strumento comunemente usato in informatica per l’elaborazione di testi. Dai risultati non emergono differenze statisticamente significative tra il gruppo sperimentale e quello di controllo, da cui si deduce che l’attività non pare adeguata per la didattica dell’ortografia nelle fasi iniziali dello studio di una L2. Non si esclude tuttavia che l’esercizio possa essere utilmente impiegato in altri contesti didattici, per esempio al fine dello sviluppo delle competenze metalinguistiche e informatica nell’ambito dei corsi di umanistica digitale. Metalinguistic activities on computers support the development of spelling competence in Italian L2 learners The paper describes and evaluates a computer-based activity aimed at improving the orthographic competence of a group of Polish first-year L2 Italian students. The target structure was the pronunciation of the letter , which varies depending on the orthographic context. The purpose of the exercise was to elaborate the corresponding set of rules using regular expressions, a tool used in IT for string processing. The results do not highlight any significant differences between the experimental and the control group. It is argued that, while the activity is not appropriate for the teaching of orthography in the initial stages of acquisition, it could be useful in developing metalinguistic and IT skills within a degree course in digital humanities.

description: La ricerca esplora il ruolo dei segnali discorsivi (SD) di tipo interazionale nella dinamica delle conversazioni di apprendenti spagnoli di italiano (di livello di competenza A2) impegnati in due diversi tipi di interazione: nativo-non nativo (asimmetrico) e non nativo-non nativo (simmetrico). L’analisi prende in considerazione due contesti conversazionali: nel primo, gli apprendenti sono impegnati in un’attività più guidata consistente nello scambio di informazioni, nel secondo nella costruzione un dialogo basato su uno scenario predefinito, come quello di decidere un regalo o organizzare una festa per un amico. Nelle conversazioni asimmetriche il dominio dei nativi nel guidare la conversazione dei non nativi emerge dalla presenza di un maggior numero di segnali di accordo e conferma di ricezione da parte degli apprendenti. D’altra parte, nelle interazioni simmetriche, la varietà e la frequenza dei vari SD utilizzati dai non nativi, come la presa di turno, la richiesta di conferma, mostrano un maggiore coinvolgimento degli stessi nell'interazione, soprattutto nel caso delle interazioni più libere (role-play). Native/non-native and non-native/non native interaction: discourse markers in Spanish-speaking learners of Italian L2 This study explores the role of interactional DM in the dynamics of conversations of Spanish native speakers (with A2 level of proficiency) engaged in two different interaction types: native/ non-native (asymmetric) and non-native/non-native (symmetric). Eight learners and two native speakers were involved in two conversational settings: in the first, pairs were engaged in an information exchange activity, in the second they had to construct a dialogue based on a predefined scenario, such as deciding on a gift or organizing a party for a friend. In asymmetrical conversations the dominance of natives in guiding the conversation of non-natives can be shown based on the greater number agreement and acknowledgment signals used by the learners. On the other hand, in symmetrical interactions, the variety and the frequency of various DMs used by non-natives, such as turn taking and requesting confirmation, shows greater involvement in the interaction, especially in role-play situations.

Supralaryngeal mechanisms of the voicing contrast in velars

description: This study investigates supralaryngeal mechanisms of the two way voicing contrast among German velar stops and the three way contrast among Korean velar stops, both in intervocalic position. Articulatory data won via electromagnetic articulography of three Korean speakers and acoustic recordings of three Korean and three German speakers are analysed. It was found that in both languages the voicing contrast is created by more than one mechanism. However, one can say that for Korean velar stops in intervocalic position stop closure duration is the most important parameter. For German it is closure voicing. The results support the phonological description proposed by Kohler (1984).

description: We present a multiwavelength radio study of a sample of nearby Fanaroff-Riley class II (FRII) radio galaxies, matched with the sample of known X-shaped radio sources in size, morphological properties and redshift, using new Giant Metrewave Radio Telescope (GMRT) data and archival data from the Very Large Array (VLA). Our principal aim in this paper is to provide a control sample for earlier studies of samples of `X-shaped' radio sources, which have similar luminosities and small-scale radio structures to our targets but exhibit large-scale extensions to their lobes that more typical FRII sources lack; earlier spectral work with the GMRT has suggested that these `wings' sometimes have flat spectral indices at low frequencies, in contrast to expectations from models in which the wings are formed hydrodynamically or by jet reorientation. In our new observations we find that almost all of our target FRII radio galaxies show standard spectral steepening as a function of distance from the hotspot at the low frequencies (610 MHz and 240 MHz) provided by the GMRT data, even when transverse extensions to the lobes are present. However, one source, 3C321, has a low-surface-brightness extension to one lobe that shows a flatter spectral index than the high-surface-brightness hotspots/lobes, as found in X-shaped sources.

“PENSO CHE CI SONO PROBLEMI CON ARTICOLI E PREPOSIZIONI”: DISAGIO LINGUISTICO NELLA CLASSE DI ITALIANO L2
Creators: name: De Tommaso, Valeria

description: Studi sul legame tra rappresentazione dell’errore e disagio linguistico in studenti universitari di lingue straniere evidenziano una visione della lingua intesa come norma e una marcata preoccupazione da parte dei discenti per la competenza linguistica (soprattutto morfosintassi, fonologia, lessico) invece che per la competenza pragmatica, flessibilità e/o efficacia comunicativa; tuttavia, gli studenti considerano l’errore un elemento costitutivo del processo di acquisizione per il quale chiedono all’insegnante un costante intervento per segnalarlo e correggerlo. Partendo da queste considerazioni, si è voluto osservare se la “paura dell’errore” corrisponda alla sua effettiva realizzazione nei testi e se una riflessione sulla distanza percepita tra L1 e L2 può essere utilizzata in favore di un processo di insegnamento/apprendimento che ridimensioni la natura dell’insicurezza linguistica. La ricerca ha coinvolto due gruppi di studenti universitari cechi e slovacchi di italiano L2. I risultati indicano che attraverso lo sviluppo della competenza metalinguistica è possibile sia rafforzare la dimensione comunicativo-pragmatica della lingua, sia rivalutare la natura dell’errore in favore di un apprendimento linguistico meno ansiogeno e più consapevole. “I think there are problems with articles and prepositions”: an experience of linguistic discomfort in an Italian L2 class Research into connections between errors and linguistic insecurity among university students in foreign language classes have drawn attention to the fact that learners concentrate on the normative aspects of language and that they are more worried about their linguistic competence (above all morphosyntax, phonology and lexicon) than pragmatic competence or communicative flexibility/efficacy. Nonetheless, they consider errors as basic elements of the learning process and therefore they ask the teacher for constant feedback and correction. Starting from these considerations, we examined whether the “fear of making errors” corresponded to the actual presence of errors in texts, and if reflection on the perceived distance between L1 and L2 can be useful in the teaching/learning process, in order to revise the nature of language insecurity. Two groups of Czech and Slovak students of Italian L2 were involved in this study. Results show that by developing metalinguistic competence, the communicative and pragmatic view on language are strengthened; in addition, errors are positively reevaluated and they are instrumental in reducing the feeling of anxiety or in increasing awareness of the language learning process.

description: Questo contributo prende le mosse da un’indagine finalizzata ad esplorare le pratiche di glottodidattica a distanza attivate da un campione di oltre 1.500 insegnanti di lingue e tutor dell’apprendimento durante il primo periodo dell’emergenza da COVID-19. In questo articolo, in particolare, si focalizzerà l’attenzione sui dati raccolti circa le problematiche relative all’inclusione degli alunni con Disturbi Specifici dell’Apprendimento (DSA) nelle attività glottodidattiche a distanza. I dati sono stati raccolti per mezzo di un questionario, e analizzati sul piano sia quantitativo sia qualitativo. Dopo una breve introduzione al contesto socio-educativo e scientifico dell’indagine, si presenterà il disegno di ricerca e si illustreranno alcuni risultati-chiave riguardanti l’esperienza sia degli insegnanti di lingue sia dei tutor che sono riusciti a seguire gli apprendenti con DSA a distanza durante il periodo di emergenza sanitaria. Distance language teaching and the inclusion of learners with dsa: a survey of language teaching practices activated during the COVID-19 emergency The present paper stems from a survey on distance language teaching practices employed by a sample of more than 1.500 Italian language teachers and tutors during the first months of the COVID-19 emergency period. Specifically, this paper focuses on the issues related to the inclusion of students with Specific Learning Differences (SpLD) in distance language education. The data were collected by means of a questionnaire and analyzed both quantitatively and qualitatively. After briefly introducing the socio-educational and scientific context of the survey, the paper outlines the research design and discusses some key results regarding the experience of both the language teachers and the tutors who supported learners with SpLD during the health emergency.

description: We show that many classical decision problems about 1-counter omega-languages, context free omega-languages, or infinitary rational relations, are $Π_2^1$-complete, hence located at the second level of the analytical hierarchy, and "highly undecidable". In particular, the universality problem, the inclusion problem, the equivalence problem, the determinizability problem, the complementability problem, and the unambiguity problem are all $Π_2^1$-complete for context-free omega-languages or for infinitary rational relations. Topological and arithmetical properties of 1-counter omega-languages, context free omega-languages, or infinitary rational relations, are also highly undecidable. These very surprising results provide the first examples of highly undecidable problems about the behaviour of very simple finite machines like 1-counter automata or 2-tape automata.
