description: Recently proposed nonholonomic deformation of the KdV equation is solved through inverse scattering method by constructing AKNS-type Lax pair. Exact and explicit N-soliton solutions are found for the basic field and the deforming function showing an unusual accelerated (decelerated) motion. A two-fold integrable hierarchy is revealed, one with usual higher order dispersion and the other with novel higher nonholonomic deformations.

description: Il contributo illustra e discute lo sviluppo di competenze metalinguistiche in alunni di classi plurilingui di scuola primaria italiana, come esito di laboratori di esplorazione linguistica secondo la modalità dell’ Éveil aux langues (Candelier et al. 2007). I risultati della prova finale dei laboratori, condotta individualmente e in piccolo gruppo, mostra che gli alunni sono in grado di riadoperare efficacemente, con un approccio metalinguistico esplicito nell’analisi di fenomeni morfologici in lingue sconosciute, le conoscenze e abilità acquisite nel corso dei laboratori attraverso l’esposizione e la riflessione induttiva intorno a una varietà di lingue; mostrano inoltre come gli alunni sappiano, a questo scopo, richiamare in modo autonomo e sfruttare dove opportuno conoscenze relative alle lingue del proprio repertorio. L’approccio di éveil aux langues utilizzato si conferma quindi promettente non solo per sviluppare un atteggiamento positivo nei confronti del plurilinguismo e della diversità linguistica, ma anche per l’acquisizione di competenze metalinguistiche mature. When children are linguists. Observing metalinguistic competence in an Éveil aux langues workshop The paper shows how metalinguistic competences developed in Italian primary school pupils thanks to linguistic workshops organized according to the Éveil aux langues (Candelier et al. 2007) program. Results from the final session activities show that pupils were able to exploit knowledge and abilities developed during the workshop in order to draw hypothesis and analyze morphosyntactic phenomena of unknown languages; they were also able to recall their linguistic competences in their own language repertoire in order to further advance and check hypotheses about language structures. The Éveil aux langues approach proves, therefore, to be helpful not only in developing a positive attitude towards languages and multilingualism, but also in developing more mature metalinguistic competences.

description: We study a physical system consisting of non-interacting quasiparticles in disordered superconductors that have neither time-reversal nor spin-rotation invariance. This system belongs to class D within the recent classification scheme of random matrix ensembles (RME) and its phase diagram contains three different phases: metallic and two distinct localized phases with different quantized thermal Hall conductances. We find that critical exponents describing different transitions (insulator-to-insulator and insulator-to-metal) are identical within the error of numerical calculations and also find that critical disorder of the insulator-to-metal transition is energy independent.

description: Prolonged experimental attempts to find magnetic monopoles (i.e., elementary particles with an isolated magnetic charge in three dimensions) have not yet been successful despite intensive efforts made since Dirac's proposal in 1931. Particle physicists have predicted the possible collision and pair annihilation of two magnetic charges with opposite signs. However, if such annihilation exists, its experimental observation would be difficult because its energy scale is predicted to be tremendously high ($\sim$10$^{16}$ GeV). In the present work, we theoretically predict using the Floquet theory that a pair of slightly gapped Dirac-cone bands in a weakly-charge-ordered organic conductor $α$-(BEDT-TTF)$_2$I$_3$, which behave as magnetic charges with opposite signs in the momentum space, exhibit pair annihilation under irradiation with linearly polarized light. This photoinduced pair annihilation is accompanied by a non-topological phase transition to the Floquet normal insulator phase in contrast to the well-known circularly-polarized-light-induced topological phase transition to the Floquet Chern insulator phase. We discuss that $α$-(BEDT-TTF)$_2$I$_3$ has a peculiar band structure capable of realizing a suitable experimental condition (i.e., off-resonant condition) and a charge ordered state providing a required staggered site potential and thereby provides a rare example of materials that can be used to observe the predicted pair annihilation phenomenon. The feasibility of experimental observation is also discussed.

description: The Q matrix invented by Baxter in 1972 to solve the eight vertex model at roots of unity exists for all values of N, the number of sites in the chain, but only for a subset of roots of unity. We show in this paper that a new Q matrix, which has recently been introduced and is non zero only for N even, exists for all roots of unity. In addition we consider the relations between all of the known Q matrices of the eight vertex model and conjecture functional equations for them.

description: Il presente contributo si inserisce nel panorama degli studi sull’educazione linguistica intesa come ambito integrato di studio di tutte le lingue che si parlano e si apprendono a scuola (L1, L2, LS) e, più in generale, di tutti i codici e le varietà con cui gli alunni entrano in contatto. Nel triennio 2014-2017 è stato implementato un Modulo Glottodidattico Sperimentale (MGS) in alcune classi multietniche (alunni di 11-13 anni), con lo scopo di promuovere e valorizzare la diversità linguistica e culturale degli alunni attraverso metodologie d’insegnamento e modalità di verifica adeguate alle caratteristiche di eterogeneità linguistica di queste classi. Seguendo i principi dell’approccio dialogico e della didattica integrata delle lingue il MGS si è avvalso, nella fase implementativa, dell’insegnamento contemporaneo di quattro lingue curricolari, del ricorso a pratiche spontanee e guidate di translanguaging, di confronti intra- e interlinguistici, di narrazioni e real life task. Nella fase di verifica sono stati progettati test in grado di tener conto sia della competenza plurilingue degli alunni, sia dell’interdipendenza tra le lingue che compongono il loro repertorio. Dopo aver fornito alcune coordinate teorico-metodologiche, vengono presentate le diverse fasi di implementazione del MGS e i risultati raggiunti. Cooperative methodologies and mobile technologies for a plurilingual education This article is part of a series of studies on language education, in the sense of an integrated field of study of all languages that are spoken and learned at school and, more generally, of all the languages and their varieties which students come into contact with. From 2014-2017, a Modulo Glottodidattico Sperimentale (MGS) was implemented in some multiethnic classes (11-13 y/o pupils), with the aim of promoting and enhancing the linguistic and cultural diversity of pupils, through appropriate teaching and assessment methods suitable to the linguistic heterogeneity of these classes. Following the principles of the “dialogical approach” and the “integrated didactic approach to languages”, the MGS availed itself, during the implementation phase, of the simultaneous teaching of four languages, the use of spontaneous practices and guided translanguaging, intra- and interlinguistic comparisons and real-life tasks. During the assessment phase, tests were designed that took into account both the pupils' plurilingual competence and the interdependence between languages that made up their repertoire. After providing some theoretical-methodological coordinates, the different implementation phases of the MGS and the results achieved are presented.

description: We compare mid-IR and ALMA far-IR images of 12 nearby Seyferts selected from GATOS. The mid-IR unresolved emission contributes more than 60% of the nuclear emission in most galaxies. By contrast, the ALMA 870micron continuum emission is mostly resolved and typically along the torus equatorial direction (Paper I, Garcia-Burillo et al. 2021). The Eddington ratios and nuclear hydrogen column densities NH of half the sample are favorable to launching polar and/or equatorial dusty winds, according to simulations. Six show mid-IR extended emission in the polar direction as traced by the NLR and perpendicular to the ALMA emission. In a few, the nuclear NH might be too high to uplift large quantities of dusty material along the polar direction. Five galaxies have low NH and/or Eddington ratios and thus polar dusty winds are not likely. We generate new CAT3D-WIND disk-wind model images. At low wind-to-disk cloud ratios the far-IR model images have disk- and ring-like morphologies. The X-shape associated with dusty winds is seen better in the far-IR at intermediate-high inclinations for the extended-wind configurations. In most models, the mid-IR emission comes from the inner part of the disk/cone. Extended bi-conical and one-sided polar mid-IR emission is seen in extended-wind configurations and high wind-to-disk cloud ratios. When convolved to our resolution, the model images reproduce qualitative aspects of the observed morphologies. Low-intermediate wind-to-disk ratios are required to account for the large fractions of unresolved mid-IR emission. This work and Paper I provide observational support for the torus+wind scenario. The wind component is more relevant at high Eddington ratios and/or AGN luminosities, and polar dust emission is predicted at NH of up to $10^{24}$cm$^{-2}$. The torus/disk component, on the other hand, prevails at low luminosities and/or Eddington ratios. (Abridged)

Introduction: Influenza infections contribute to excess healthcare utilization, morbidity, and mortality in individuals with glomerular disease (GD); however, influenza vaccination may not yield protective immune responses in this high-risk patient population. The objective of the present study was to describe influenza vaccine administration from 2010 to 2019 and explore the effectiveness of influenza vaccination in patients with GD. Methods: We conducted an observational cohort study using healthcare claims for seasonal influenza vaccination (exposure) as well as influenza and influenza-like illness (outcomes) from commercially insured children and adults <65 years of age with primary GD in the Merative MarketScan Research Databases. Propensity score-weighted cox proportional hazards models and ratio-of-hazard ratios (RHR) analyses were used to compare influenza infection risk in years where seasonal influenza vaccines matched or mismatched circulating viral strains. Results: The mean proportion of individuals vaccinated per season was 23% (range 19%-24%). In pooled analyses comparing matched to mismatched seasons, vaccination was minimally protective for both influenza (RHR 0.86, 95% confidence interval [CI]: 0.52-1.41) and influenza-like illness (RHR 0.86, 95% CI 0.59-1.24), though estimates were limited by sample size. Conclusion: Rates of influenza vaccination are suboptimal among patients with GD. Protection from influenza after vaccination may be poor, leading to excess infection-related morbidity in this vulnerable population.
LA DIVERSITÀ DELLA TRADIZIONE GLOTTODIDATTICA COME OSTACOLO AL RINNOVAMENTO DELL’INSEGNAMENTO DELLA LINGUA ITALIANA IN RUSSIA

description: L’articolo presenta i risultati dell’analisi di due manuali di italiano LS che sono da tempo presenti sul mercato editoriale russo, ciascuno figlio della propria tradizione glottodidattica, quella russo-sovietica e quella italiana. Si riflette sulle ragioni per le quali il manuale tradizionale russo ha ancora tanto successo tra gli insegnanti di rilievo mentre invece quello italiano, nonostante i suoi numerosi meriti, stenta a diffondersi nelle cattedre più prestigiose. Per l’analisi comparativa è stata elaborata una lista di criteri che, per mancanza di fonti italofone, prende spunto da lavori di autori russi, britannici e polacchi e può essere utilizzata per la valutazione di qualsiasi manuale di lingua straniera. Alla fine dell’articolo si propone una soluzione per poter riconciliare le due tradizioni glottodidattiche in modo che gli studenti russi possano godere pienamente di materiali aggiornati, autentici e altamente motivanti senza dover rinunciare al meglio della tradizione russo-sovietica radicata così profondamente sul territorio nazionale. Traditional language teaching as an obstacle to the renewal of the Italian language teaching in Russia The article summarizes the results of the analysis of two coursebooks for Italian as a foreign language available on the Russian publishing market. One of them was written by a Russian author and represents a quintessence of the Soviet-Russian cognitive comparative approach to teaching foreign languages. The other is a product of a team of Italian experts. We ponder on the reasons why the older Russian textbook is still so successful among teachers of Italian and why it is still difficult to convince them of the need to adopt newer materials and reform the old curricula. A list of criteria was developed in order to carry out a comparative analysis of the two coursebooks. Some works by Russian, British and Polish authors turned out to be useful for the compilation of the list, since there are no works on the subject in Italian. The list could be useful for the evaluation of almost any foreign language textbook. At the end of the article, we propose a solution for reconciliation between the two didactic traditions that could give Russian students a chance to take advantage of modern, authentic and highly motivating materials without the need to abandon the local teaching tradition that is so deeply rooted in Russia.

description: We consider a mixed stochastic control problem that arises in Mathematical Finance literature with the study of interactions between dividend policy and investment. This problem combines features of both optimal switching and singular control. We prove that our mixed problem can be decoupled in two pure optimal stopping and singular control problems. Furthermore, we describe the form of the optimal strategy by means of viscosity solution techniques and smooth-fit properties on the corresponding system of variational inequalities. Our results are of a quasi-explicit nature. From a financial viewpoint, we characterize situations where a firm manager decides optimally to postpone dividend distribution in order to invest in a reversible growth opportunity corresponding to a modern technology. In this paper a reversible opportunity means that the firm may disinvest from the modern technology and return back to its old technology by receiving some gain compensation. The results of our analysis take qualitatively different forms depending on the parameters values.

L1 E TRADUZIONE DIDATTICA NEL TEACHER TALK DEGLI INSEGNANTI DI ITALIANO E DI INGLESE COME LINGUE STRANIERE PER SCOPI SPECIALISTICI

description: Nelle ricerche glottodidattiche di lingue straniere/seconde relativamente scarsa l’attenzione è indirizzata alla ricerca empirica del teacher talk, il parlato degli insegnanti usato in classe, particolarmente scarsa risulta quella riferita al parlato degli insegnanti di lingue straniere per obiettivi specialistici. Inoltre, in quest’ambito le ricerche sull’utilizzo intenzionale di L1 e della traduzione didattica tra gli insegnanti di LSsp sono quasi inesistenti. Pertanto, il presente studio si premette di indagare sull’uso di L1 e traduzione didattica, in base all’analisi qualitativa in classi ‘italiane’ e ‘inglesi’ osservate, mirando in particolare alle differenze tra gli insegnanti d’italiano e d’inglese, e agli usi di traduzione didattica come tecnica per sviluppare competenze produttive nei generi testuali della LSsp. Gli esiti ci inducono alla conclusione che la traduzione didattica si usa occasionalmente, per la precisazione terminologica in entrambe le lingue, invece le modalità ‘sussurrate’ tra le insegnanti d’italiano LSsp suggeriscono più disagi rispetto alle colleghe d’inglese. In comune a entrambi gruppi di docenti osservate è una forte tendenza a non usare la Traduzione didattica o L1, neanche come sostegno per far imparare a scrivere generi settoriali. L1 and didactic translation in the teacher talk of teachers of Italian and English as foreign languages for special purposes In foreign/second language teaching research, relatively little attention is paid to empirical studies on teacher talk, i.e. FL teachers’ speech used in the classroom, and even fewer analyses refer to the teacher talk of FL teachers for specific purposes. Furthermore, research on the intentional use of L1 and pedagogical translation (PT) among FLsp teachers is almost absent. Therefore, the present study investigates the use of L1 and pedagogical translation based on qualitative analyses of observations in 'Italian' and 'English' classes that focus in particular on differences between teachers of Italian and English, as well as on the uses of pedagogical translation as a technique to develop productive skills in professional genres. The results lead to the conclusion that pedagogical translation is used occasionally, mainly for terminological clarifications in both languages, however the ‘whispered’ modalities of L1 use among Italian LSsp teachers seem to indicate greater insecurity with respect to English colleagues. Both groups of FLsp teachers displayed strong tendencies to avoid using L1 and PT, not even as support in learning to write in professional genres.

LA COMUNICAZIONE DELL’INSEGNANTE DURANTE LA LEZIONE D’ITALIANO IN CONTESTO SCOLASTICO UNGHERESE: CARATTERISTICHE COMUNI E STRATEGIE INDIVIDUALI
Creators: name: Huszthy, Alma
Publisher: name: Italiano LinguaDue

description: Nel corso dell’apprendimento di una lingua straniera la comunicazione dell’insegnante risulta di primaria importanza: essa fa parte integrante dell’input linguistico a cui gli studenti sono esposti, anzi costituisce l’unico modello linguistico diretto e vivo durante le lezioni. Nel contesto scolastico fuori del paese target, il fatto che l’insegnante di lingua generalmente non sia nativo complica ulteriormente la situazione costringendolo a operare una serie di scelte riguardanti i vari processi comunicativi con gli studenti. Partendo da questa problematica in questo contributo vorrei presentare un panorama complesso per quanto riguarda la comunicazione del docente non nativo di italiano nel contesto scolastico ungherese e svelare concezioni, riflessioni e decisioni all'origine delle soluzioni individuali che ho avuto la possibilità di osservare. In base alle riprese audio effettuate durante le osservazioni in 8 licei nel quadro di 11 lezioni, e alle 8 interviste strutturate rivolte ai docenti di italiano, esamino il parlato spontaneo istituzionale del docente d’italiano non nativo. Teacher talk during Italian lessons in Hungarian schools: common characteristics and individual strategies Teacher talk is of primary importance during foreign language learning: it is part of the linguistic input to which learners are exposed, the only directly accessible and live linguistic model in the classroom. In the school context, outside the target country, that the language teacher is usually non-native complicates the situation even more: the teacher is forced to make a lot of choices about the process of communication in the classroom. Starting from this issue, the article presents a complex survey on non-native teacher talk in Hungarian schools and exposes conceptions, reflections and decisions at the origin of individual solutions which I had the chance to see. Based on audio recordings made during teacher observations in 8 high schools (during 11 lessons) and 8 interviews, I examine the spontaneous teacher talk of non-native Italian teachers.

INSEGNARE L’ITALIANO A STUDENTI CROATI: SISTEMA TEMPORALE E ASPETTO VERBALE (IMPERFETTO E PASSATO PROSSIMO)

description: L’articolo riferisce i risultati e le considerazioni, anche in termini di proposta didattica, emersi dall’analisi della produzione scritta in lingua italiana di studenti croatofoni delle università di Zagabria e di Fiume (Rijeka) riguardo l’apprendimento del sistema temporale italiano. Nello specifico sono state studiate le modalità di selezione e di uso combinato dei tempi imperfetto e passato prossimo del modo indicativo. Nonostante una certa corrispondenza tra i tempi passati delle due lingue sia a livello morfologico che aspettuale, condizioni per un transfer positivo, gli studenti hanno incontrato problemi nella scelta del tempo adeguato in determinati casi. Ciò riflette le differenze tra le due lingue riguardo la valenza di alcuni avverbiali temporali, l’uso delle perifrasi verbali, ecc. L’analisi contrastiva risulta preziosa in quanto strumento di riflessione in classe e di osservazione per l’insegnante. Ad essa però debbono affiancarsi specifiche attività didattiche (“fare con la lingua”), che vanno a integrare la componente metalinguistica della glottodidassi, rafforzando le abilità linguistiche in corso di sviluppo. In questo contributo si presentano tre attività task-based che hanno portato a un netto miglioramento nell’impiego dei due tempi passati. Teaching italian to Croatian students: time and verbal aspects (‘imperfetto’ and ‘passato prossimo’) The article reports the results and considerations, also in terms of teaching proposals, that emerged from the analysis of the written production in Italian of Croatian-speaking students at the universities of Zagreb and Rijeka regarding learning the Italian tense system. Specifically, the selection methods and combined use of the imperfect (imperfetto) and the perfect (passato prossimo) of the indicative mode were studied. In spite of a certain correspondence between the past tenses of the two languages on both morphological and aspectual levels, conditions for a positive transfer, students encountered problems in choosing the appropriate tense in certain cases. This reflects the differences between the two languages with regard to the value of some temporal adverbials, the use of verbal periphrases, etc. Contrast analysis is valuable as a classroom reflection and observation tool for the teacher. However, it must be accompanied by specific teaching activities (“doing using language”), which integrate the metalinguistic component of the language teaching, strengthening the linguistic skills being developed. The paper presents three task-based activities that led to a clear improvement in the use of the two past tenses.

description: We present a survey of the ortho-H2D+(1_{1,0}-1_{1,1}) line toward a sample of 10 starless cores and 6 protostellar cores, carried out at the Caltech Submillimeter Observatory. The high diagnostic power of this line is revealed for the study of the chemistry, and the evolutionary and dynamical status of low-mass dense cores. The line is detected in 7 starless cores and in 4 protostellar cores. N(ortho-H2D+) ranges between 2 and 40x10^{12} cm^{-2} in starless cores and between 2 and 9x10^{12} cm^{-2} in protostellar cores. The brightest lines are detected toward the densest and most centrally concentrated starless cores, where the CO depletion factor and the deuterium fractionation are also largest. The large scatter observed in plots of N(ortho-H2D+) vs. the observed deuterium fractionation and vs. the CO depletion factor is likely to be due to variations in the ortho-to-para (o/p) ratio of H2D+ from >0.5 for T_{kin} < 10 K gas in pre-stellar cores to ~0.03 (consistent with T_{kin} ~15 K for protostellar cores). The two Ophiuchus cores in our sample also require a relatively low o/p ratio (~0.3). Other parameters, including the cosmic-ray ionization rate, the CO depletion factor (or, more in general, the depletion factor of neutral species), the volume density, the fraction of dust grains and PAHs also largely affect the ortho-H2D+ abundance. The most deuterated and H2D+-rich objects (L429, L1544, L694-2 and L183) are reproduced by chemical models of centrally concentrated (central densties ~10^{6} cm^{-3}) cores with chemical ages between 10^4 and 10^6 yr. Upper limits of the para-H3O+ (1_1- -2_1+) and para-D2H+ (1_{1,0}-1_{0,1}) lines are also given. (Abridged)

description: L’insegnamento della lingua italiana nella zona multietnica e multilingue del litorale sloveno – sia nelle cosiddette scuole della comunità di minoranza nazionale italiana che in quelle di lingua di maggioranza – è presente e regolarizzato con caratteristica di obbligatorietà fin dal secondo dopoguerra, conseguentemente a trattati internazionali che ne hanno definito finalità e organizzazione. Tuttavia recenti ricerche sottolineano importanti criticità evincibili sia dai risultati di test di apprendimento della lingua italiana tra i ragazzi dell’ultimo anno della scuola primaria (15 anni) con lingua di maggioranza di questa area, molto bassi rispetto a quelli del passato e molto al di sotto dei livelli minimi di apprendimento previsti ministerialmente per quanto riguarda sia gli atteggiamenti verso la stessa lingua sia gli aspetti curricolari e didattici. L’intervento descrive una nuova proposta metodologica originatasi nell’ambito di una ricerca di dottorato che ha dato inizio alla definizione e studio della “Didattica del contatto” (traduzione dell’acronimo CoBLaLT- Contact Based (Neighbouring) Language Learning and Teaching) la quale vuole presentare un approccio innovativo per l’insegnamento dell’italiano nelle scuole primarie di lingua di maggioranza nel litorale sloveno basato sull’uso metodologico dei contatti sia virtuali che reali tra ragazzi delle scuole del litorale sloveno e ragazzi delle scuole italiane nelle province di Trieste (questi ultimi apprendenti la lingua slovena). Teaching Italian and the didactics of contact in multilingual border areas: a methodological proposal The teaching of Italian in the multi-ethnic and multilingual area of ​​the Slovenian coast – both in the schools for the Italian minority community and in those of the majority language – has been mandatory since the second post-war period, following international treaties (London Memorandum; Treaty of Osimo) which defined its purpose and organization. However, recent research underlines important critical issues from the results of the Italian language learning tests among children in the last year of mainstream primary school (15 years) in this area. Their results are very low compared to past results and fall far below the minimum level of learning- both in attitudes regarding the Italian language and in curricular and didactic aspects. The paper describes a new methodological proposal, originating from a doctoral research project that invented and defined the CoBLaLT- Contact Based (Neighboring) Language Learning and Teaching methodology, in an effort to introduce an innovative approach for teaching Italian in the majority language primary schools on the Slovenian coast. The approach is based on the methodological use of both virtual and real contact between school children on the Slovenian coast and children from Italian

The role of anthrax in the population biology of wildebeest in the Selous Game Reserve

description: Anthrax was associated with the death of a large number of animals in the Selous Game Reserve. The significance of this disease to the populations of these animals was of concern to the reserve's management. Models are presented of the evolutionary effects of four host-pathogen relationships. Based on a demographic study of the wildebeest and a study of the characteristics of the disease, the anthrax-wildebeest relationship was compared with the models. The results of the study indicate that even though anthrax was responsible for the death of approximately 10% of the wildebeest, it had a balanced relationship with the population. The pathogen was probably an asset to its host population's continued existence rather than a hazard, as its mortality was associated with animals that appeared to be a disadvantage to the wildebeest population. If the management of the reserve wished to reduce the occurrence of anthrax, it is suggested that they reduce the number of wildebeest older than calves. In addition to maintaining a stable age configuration, this would improve the quality of the habitat, reduce the number of animals in poor condition, and thus reduce the number dying of anthrax. In addition, I deal with several other topics in Appendices.

description: Microresonator frequency combs based on the $χ^{(3)}$ nonlinearity are nowadays well understood and making their way into different applications. Recently, microresonator frequency combs based on the $χ^{(2)}$ nonlinearity are receiving increasing attention, as they promise certain benefits, but still require further study. Here, we demonstrate the generation of a $χ^{(2)}$ frequency comb, initiated via optical parametric oscillation (OPO) in a lithium niobate mm-sized microresonator. By pumping at 532 nm with 30 $μ$W of power, we observe 1-THz-wide comb spectra around 1064 nm with degenerate and non-degenerate states. We also show that comb generation requires signal and idler waves to be degenerate in mode numbers and how the fulfillment of this condition can be identified from the temperature tuning curves. The results demonstrate the potential to directly generate frequency combs via OPO beyond 3 $μ$m wavelengths in the mid-IR by puming in the near-IR region.

description: We study evolutionary game dynamics in a well-mixed populations of finite size, N. A well-mixed population means that any two individuals are equally likely to interact. In particular we consider the average abundances of two strategies, A and B, under mutation and selection. The game dynamical interaction between the two strategies is given by the 2x2 payoff matrix [(a,b), (c,d)]. It has previously been shown that A is more abundant than B, if (N-2)a+Nb>Nc+(N-2)d. This result has been derived for particular stochastic processes that operate either in the limit of asymptotically small mutation rates or in the limit of weak selection. Here we show that this result holds in fact for a wide class of stochastic birth-death processes for arbitrary mutation rate and for any intensity of selection.

IMPACT OF MEDIA IN VOCABULARY LEARNING AND TEACHING-LEARNING SETTINGS: A QUASI-EXPERIMENT IN ITALIAN AS HERITAGE LANGUAGE CLASSES
Creators: name: Brocca, Nicola
Publisher: name: Italiano LinguaDue
Year: 2021

description: Heritage language classes comprise a favorable environment for the application of innovative methods sustained by new technologies for foreign learning acquisition. This preliminary study describes an experiment in classes of Italian as heritage language in Germany. The involved teachers employ, during the input-phase, didactical videos as opposed to traditional written material on paper. Through a small-N quantitative analysis, the groups taught by videos demonstrate a lexical improvement marginally higher than the groups taught by paper. From the qualitative analysis, significant changes in the learning environment emerge: in the groups taught by videos, higher interactions were registered and the learning process showed numerous elaborations (from an audiovisual input to written notes, which are rewritten in the working sheets). The observations confirm multifactorial implications within the didactical setting (Calvani & Vivanet, 2014) previously never studied within heritage languages classes in Germany. Impatto dei media nell’apprendimento del vocabolario e nel setting di insegnamento-apprendimento: un esperimento in classi di italiano come lingua d’origine Le classi di lingua d’origine offrono un ambiente particolarmente favorevole per l’applicazione di nuove tecnologie didattiche. Questo studio preliminare descrive un esperimento in classi di italiano come lingua d’origine in Germania dove gli insegnanti hanno usato video didattici in sostituzione di materiali cartacei tradizionali nella fase di introduzione delle informazioni. Nonostante un campione ristretto l’analisi quantitativa mostra che i gruppi che hanno fatto ricorso ai video registrano un apprendimento del lessico leggermente migliore dei gruppi che si sono basati sulla lettura. L’analisi qualitativa dimostra che l’apprendimento avviene in modo notevolmente diverso: nei gruppi che ricevono istruzioni attraverso i video le interazioni sono maggiori e il processo di apprendimento passa per numerose elaborazioni (da input audiovisivo a appunti scritti, per venire poi nuovamente trascritto nei fogli di lavoro). L’osservazione conferma l’esistenza di conseguenze multifattoriali delle tecnologie sul setting didattico (Calvani & Vivanet, 2014) anche in un ambiente mai precedentemente analizzato sperimentalmente come le classi di lingua d’origine in Germania.

The Effect of Gas Physics on the Halo Mass Function

description: Cosmological tests based on cluster counts require accurate calibration of the space density of massive halos, but most calibrations to date have ignored complex gas physics associated with halo baryons. We explore the sensitivity of the halo mass function to baryon physics using two pairs of gas-dynamic simulations that are likely to bracket the true behavior. Each pair consists of a baseline model involving only gravity and shock heating, and a refined physics model aimed at reproducing the observed scaling of the hot, intracluster gas phase. One pair consists of billion-particle re-simulations of the original 500 Mpc/h Millennium Simulation of Springel et al. (2005), run with the SPH code Gadget-2 and using a refined physics treatment approximated by preheating (PH) at high redshift. The other pair are high-resolution simulations from the adaptive-mesh refinement code ART, for which the refined treatment includes cooling, star formation, and supernova feedback (CSF). We find that, although the mass functions of the gravity-only (GO) treatments are consistent with the recent calibration of Tinker et al. (2008), both pairs of simulations with refined baryon physics show significant deviations. Relative to the GO case, the masses of ~10^{14} Msun/h halos in the PH and CSF treatments are shifted by averages of -15 \pm 1 percent and +12 \pm 5 percent, respectively. These mass shifts cause ~ 30% deviations in number density relative to the Tinker function, significantly larger than the 5% statistical uncertainty of that calibration.

description: Il presente contributo descrive i principi e gli obiettivi di materiali fraseodidattici rivolti ad apprendenti dell’italiano come L2, elaborati nell'ambito del progetto “LeKo – Combinazioni lessicali e linguaggio tipizzato in contesto plurilingue”, in collaborazione tra l’Università di Innsbruck ed Eurac Research. Frutto di un approccio multidisciplinare, il progetto integra concetti teorici, metodi e risorse della ricerca fraseologica, della didattica basata sui task e della linguistica dei corpora (in particolare dei learner corpora). Attraverso la presentazione di un’unità didattica e della cornice narrativa che fa da sfondo al libro di testo, vengono messe in luce le caratteristiche salienti di un modello fraseodidattico orientato all’azione, nel rispetto di principi fondamentali della glottodidattica moderna, quali ad esempio l’autenticità del materiale e la possibilità di sviluppare le competenze comunicative in diverse situazioni della vita quotidiana e il ricorso a contesti multimediali. Developing lexical and phraseological competence through tasks. A contribution to the development of teaching material for Italian L2 The present article describes the principles and objectives of phraseodidactic materials for L2 learners of Italian. The materials were produced as part of the research project “LeKo – Lexeme combinations and typified speech in a multilingual context”, a collaboration between the University of Innsbruck and Eurac Research. Resulting from a multidisciplinary approach, the project includes theoretical concepts, methods and resources from phraseological research, task- based language teaching, as well as corpus linguistics (especially of learner corpora). By presenting a teaching unit and the textbook’s narrative framework, we will illustrate the main characteristics of the action-oriented phraseodidactic model that also reflects fundamental principles of modern language teaching such as using authentic materials, allowing students to develop their communicative skills in different everyday situations and employing various forms of media.
