description: This article ties in with a previous one, Lingua è lavoro e lavoro è lingua by Matilde Grünhage Monetti, published in Italiano LinguaDue, n. 2. 2016. Both papers present the results of the project, Deutsch am Arbeitsplatz (DaA) 1/German in the Workplace 1, funded by the Volkswagen Foundation (VW) (2007-2009). The project investigated workplace communication in Germany in sectors with a high number of migrant workers. It aimed at identifying work-related language skills requirements so as to improve the development of the second language for work for migrant employees and job seekers. While the first article discussed the results of company ethnography carried out by the DaA team, this present paper presents key results of the analysis of a corpus of authentic oral interactions and documents collected during the project and discusses the practical application of choosing recorded authentic oral interactions in training for teachers, providers of work-related L2 and in diversity training for employees of local administrations and at job centers.

Sprechen ist das Allerwichtigste / Parlare è la cosa più importante

Questo articolo è strettamente correlato a quello precedente, Lingua è lavoro e lavoro è lingua di Matilde Grünhage Monetti, pubblicato in Italiano LinguaDue, n. 2. 2016.  Entrambi gli articoli presentano i risultati del progetto, Deutsch am Arbeitsplatz (DaA) 1 / German in the Workplace 1, finanziato dalla Volkswagen Foundation (VW) (2007-2009). Il progetto ha studiato la comunicazione sul posto di lavoro in Germania in settori con un elevato numero di lavoratori migranti, con l’obiettivo di identificare i requisiti delle competenze linguistiche legate al lavoro in modo da migliorare lo sviluppo della seconda lingua per scopi professionali da parte di lavoratori migranti e di persone in cerca di lavoro. Mentre nel primo articolo si sono discussi i risultati di una ricerca di etnografia aziendale effettuata dal team DaA, in questo si presentano i risultati chiave dell’analisi di un corpus di interazioni orali autentiche e di documenti raccolti durante il progetto e discute l’applicazione pratica di una selezione di registrazioni di interazioni orali nella formazione degli insegnanti e di fornitori nella L2 di servizi per il lavoro e nella formazione alla diversità per i dipendenti delle amministrazioni locali e dei centri per l’impiego.

TPACK as a conceptual framework for the integration of technology in the teaching of Italian as foreign language in the university

The advent and widespread use of mobile devices such as cell phones, tablets and laptops is affecting learning and teaching of subjects at all levels. With these devices a series of educational activities characterized by cooperation, motivation and instant feedback can be can created and evaluated. The objective of this article is to analyze the characteristics of some of these online teaching tools which were used to carry out exercises on combined pronouns during a university course in Italian as a foreign language. The article also analyses the evaluation, by the course students, of the learning path realized with these tools. Thanks to the characteristics of digital teaching technologies used to develop these exercises, personalized and learner-centered assessment was possible. We will analyze the potential, criticality and further developments of the teaching proposal in question, from game-based learning, and provide pedagogical-didactic references that underlie the planning of these activities.

Monitoring for resilience : detecting and responding to coastal wetland change at the Mission-Aransas National Estuarine Research Reserve

description: Climate change poses unprecedented potential for wetland loss and consequences to human communities. It is important to evaluate complex, multi-scale issues, such as climate change, in the context of social-ecological systems. One vital component to resilient social-ecological systems is monitoring—monitoring acts as an effective mechanism for detecting and responding to change in the environment. The primary objective of this thesis was to evaluate the Mission-Aransas National Estuarine Research Reserve’s monitoring efforts. Designated in 2006, the Mission-Aransas NERR belongs to a system of Reserves responsible for serving as researchers and educators for their coastal communities across the United States and Puerto Rico. The Mission-Aransas NERR participates in the System-wide Monitoring Program (SWMP), a standard of the system, that collects long-term monitoring data to inform effective coastal management The SWMP consists of standard abiotic and toolbox-approach biotic data collection, sentinel monitoring of sea level rise impacts, and habitat mapping to monitor long-term changes and short-term variability in estuaries. The first objective was to examine climate-driven foundation species shifts in the salt marsh-mangrove ecotone. In the Mission-Aransas Estuary, there is a general shift toward wetland homogeneity. Wetland sites are becoming less diverse in both species’ richness and species evenness. Specifically, black mangrove shrubs and unvegetated covers are increasing in abundance at the expense of succulent and grass species at monitoring sites. The local macroclimate drivers, increasing minimum temperatures and precipitation changes, appear most influential on the estuarine emergent vegetation patterns. The second objective was to understand the role long-term monitoring data plays in management decision-making. Using qualitative methods, this section focused on Mission-Aransas NERR partners who may own or manage lands within the reserve boundaries. Conversations demonstrated the importance of working beyond boundaries to connect long-term monitoring data to management needs. While partners and other stakeholders have utilized water quality data given the freshwater inflow issues of the region, there is an increasing interest in analyzing and learning about non-NOAA funded vegetation, habitat mapping, and elevation data. Leveraging relationships and building community are solutions for connecting data to end users and demonstrating the value of long-term data for multiple use

description: Radioxenon is produced from emissions due to nuclear explosion testing and civilian sources—nuclear power plants and medical isotope facilities. Radioxenon emissions are monitored around the world by the International Monitoring System (IMS) for treaty verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). As most of the current fleet of Light-Water Reactors (LWR) will be nearing the end of their lifespan in the mid-2030s, the next generation of nuclear power reactors are being developed. One type of these next-generation reactors, molten salt reactors (MSR), and their chemical reprocessing facilities have the potential to release significant quantities of radioxenon, thus, impeding the Comprehensive Nuclear-Test-Ban Treaty Organization’s (CTBTO) ability to monitor for nuclear explosion testing. This research looked at designing an abatement system for a future 1MW MSR research reactor and its implications for nuclear explosion monitoring

Angiogenic factors in placentally-mediated pregnancy complications
Creators: name: Benton, Samantha Jayne
Publisher: name: University of British Columbia
Year: 2014

description: Placentally-mediated pregnancy complications include pre-eclampsia, intrauterine growth restriction (IUGR), placental abruption and some causes of stillbirth. These complications are believed to arise from abnormal placental development in early gestation that leads to compromised placental function in later pregnancy which can adversely affect both mother and fetus. It is a priority in obstetrics to identify these pregnancies early and accurately so that appropriate monitoring and intervention can optimise outcomes for these mothers and babies. Novel biomarkers such as angiogenic factors in the maternal circulation may improve the prediction and/or diagnosis of these complications by adding to the information gained from tools already used in clinical practice. In this thesis, I investigated angiogenic factors in 1) the diagnosis of pre-eclampsia using new clinical immunoassays, 2) the prediction of placentally-mediated complications in a high-risk pregnancy cohort and 3) the diagnosis of placental IUGR in pregnancies with small for gestational age (SGA) fetuses. Additionally, I investigated the association between levels of circulating angiogenic factors and the presence of histopathological lesions of dysfunction in the placenta after delivery. I found that angiogenic factors, particularly low circulating placental growth factor (PlGF), had high sensitivity and specificity in the diagnosis of pre-eclampsia but all markers had poor performance as predictive markers for placentally-mediated complications. In pregnancies with SGA fetuses, low maternal PlGF discriminated between fetuses with placental IUGR (defined by the presence of histological lesions of placental dysfunction) from constitutionally small fetuses (no pathological lesions present) with high sensitivity and high negative predictive value. Additionally, low maternal PlGF in the second trimester was associated with the presence of lesions of placental dysfunction in pregnancies at high-risk for placentally-mediated complications. Low maternal PlGF was also associated with lesions of placental dysfunction as well as altered placental morphology in pregnancies with SGA fetuses. Taken together, these findings suggest that PlGF may be an antenatal marker of placental dysfunction and may provide a novel clinical tool to identify pregnancies with placental dysfunction. This work improves our understanding of angiogenic factors in placentally-mediated complications and contributes to the growing body of evidence supporting their integration in clinical practice.

description: На сегодняшний день можно с уверенностью утверждать, что туризм сформировался в качестве продукта развития цивилизации. Определенный этап развития экономики поспособствовал появлению человеческой потребности в познании мира, путешествиях, в связи с чем началось формирование производителей услуг для
удовлетворения данной потребности в лице товара особого вида – туризма. На современном этапе развития туризму присущи две основные тенденции: способность к возобновлению своих объемов в неблагоприятных обстоятельствах и предрасположенность к влиянию внешних политических и экономических факторов. Уже многие годы остро стоит вопрос о развитии туризма внутри страны, поскольку должного внимания данной области как составной части национальной экономики Российской Федерации не предоставляется. В
статье рассматривается специфика развития туристической отрасли Российской Федерации на примере Новгородской области, поскольку на сегодняшний день в сфере российской туристской индустрии возлагаются большие надежды на развитие именно внутреннего и въездного туризма.

description: We obtained precise line-of-sight radial velocities of 23 member stars of the remote halo globular cluster Palomar 4 (Pal 4) using the High Resolution Echelle Spectrograph (HIRES) at the Keck I telescope. We also measured the mass function of the cluster down to a limiting magnitude of V~28 mag using archival HST/WFPC2 imaging. We derived the cluster's surface brightness profile based on the WFPC2 data and on broad-band imaging with the Low-Resolution Imaging Spectrometer (LRIS) at the Keck II telescope. We find a mean cluster velocity of 72.55+/-0.22 km/s and a velocity dispersion of 0.87+/-0.18 km/s. The global mass function of the cluster, in the mass range 0.55<=M<=0.85 M_solar, is shallower than a Kroupa mass function and the cluster is significantly depleted in low-mass stars in its center compared to its outskirts. Since the relaxation time of Pal 4 is of the order of a Hubble time, this points to primordial mass segregation in this cluster. Extrapolating the measured mass function towards lower-mass stars and including the contribution of compact remnants, we derive a total cluster mass of 29800 M_solar. For this mass, the measured velocity dispersion is consistent with the expectations of Newtonian dynamics and below the prediction of Modified Newtonian Dynamics (MOND). Pal 4 adds to the growing body of evidence that the dynamics of star clusters in the outer Galactic halo can hardly be explained by MOND.

A cardinal $κ$ is characterized by a Scott sentence $ϕ_M$, if $ϕ_M$ has a model of size $κ$, but no model of $κ^+$. The main question in this paper is the following: Are the characterizable cardinals closed under the powerset operation? We prove that if $\aleph_β$ is characterized by a Scott sentence, then $2^{\aleph_{β+β_1}}$ is (homogeneously) characterized by a Scott sentence, for all $0

description: Il rapporto tra l’uomo e la macchina nel campo della didattica delle lingue moderne si è evoluto, fin dai primi esperimenti meccanici dell’inizio del Novecento, nella convinzione che le macchine potessero fungere da insegnanti. Tale convinzione, che disumanizza il processo di apprendimento, si è alimentata nei decenni della fiducia nelle macchine, che oggi si è ulteriormente rafforzata grazie alle TIC. Proprio le TIC, però, ci offrono la possibilità di superare il paradigma della macchina insegnante, se ne sfruttiamo le potenzialità relazionali. Le e-mail, i blog, i social media consentono di costruire un ambiente virtuale, progettato (e valutato) dal docente ma autogestito dagli studenti, con prevedibili ricadute sulla motivazione e sulla percezione di autenticità del materiale studiato. Si tratta di una potenzialità non priva di controindicazioni e insidie, che, però, possono e devono essere risolte se si vuole attribuire alla tecnologia un ruolo davvero efficace, ma nello stesso tempo non invadente, nel processo di insegnamento/apprendimento delle lingue.

Teaching machines and the virtual environment: a survey of a century of language teaching with ICT and a look at the future

The relationship between man and machine in the field of teaching modern languages has evolved, starting from the first mechanical experiments of the early twentieth century, based on the belief that machines could be teachers. This conviction, which dehumanizes the learning process, has been fueled over the decades by the confidence in machines, which today has been further strengthened thanks to ICT. But ICTs, however, offer us the possibility to overcome the paradigm of the teacher machine, if we exploit its relational potentials. E-mails, blogs, social media allow us to build a virtual environment, designed (and evaluated) by the teacher and yet self-managed by the students, with predictable consequences on the motivation and perception of the authenticity of the material studied. It is a potential not without contraindications and pitfalls, which, however, can and must be resolved if we technology to have a truly effective, but at the same time non-invasive, role in the language teaching/learning process.

description: Questo contributo esplora un campo di ricerca a cui è stata riservata un’attenzione soltanto marginale: la punteggiatura nelle scritture di “semicolti”; l’indagine viene condotta su un corpus costituito da lettere di prigionieri di guerra italiani raccolte dal filologo romanzo Leo Spitzer negli anni del primo conflitto mondiale. Dopo aver illustrato le peculiarità linguistiche delle missive, si concentra l’attenzione sull’uso dei segni interpuntivi: l’analisi rileva l’affiorare di una “coscienza testuale” negli scriventi semicolti; questi ultimi riconoscono il ruolo centrale della punteggiatura nella strutturazione del testo e pertanto di essa si avvalgono seppure con esiti che talvolta si discostano dalla norma.

Punctuation in the writing of semi-literate italians: the “letters” of Leo Spitzer

This paper explores a field of research which has been given only marginal attention: punctuation in the writing of the “semi-literate”. The investigation was conducted based on a corpus consisting of letters from Italian prisoners of war collected by the Romance language philologist Leo Spitzer during the First World War. After having illustrated the linguistic peculiarities of the missives, attention is focused on the use of inter-punctuation. The analysis reveals the emergence of a "textual conscience" in the semi-literate writers, who recognize the central role of punctuation in the structuring of the text and therefore make use of it even with outcomes that sometimes deviate from the norm.

description: We generalize the classical cow-path problem [7, 14, 38, 39] into a question that is relevant for collective foraging in animal groups. Specifically, we consider a setting in which k identical (probabilistic) agents, initially placed at some central location, collectively search for a treasure in the two-dimensional plane. The treasure is placed at a target location by an adversary and the goal is to find it as fast as possible as a function of both k and D, where D is the distance between the central location and the target. This is biologically motivated by cooperative, central place foraging such as performed by ants around their nest. In this type of search there is a strong preference to locate nearby food sources before those that are further away. Our focus is on trying to find what can be achieved if communication is limited or altogether absent. Indeed, to avoid overlaps agents must be highly dispersed making communication difficult. Furthermore, if agents do not commence the search in synchrony then even initial communication is problematic. This holds, in particular, with respect to the question of whether the agents can communicate and conclude their total number, k. It turns out that the knowledge of k by the individual agents is crucial for performance. Indeed, it is a straightforward observation that the time required for finding the treasure is $Ω$(D + D 2 /k), and we show in this paper that this bound can be matched if the agents have knowledge of k up to some constant approximation. We present an almost tight bound for the competitive penalty that must be paid, in the running time, if agents have no information about k. Specifically, on the negative side, we show that in such a case, there is no algorithm whose competitiveness is O(log k). On the other hand, we show that for every constant $ε\textgreater{} 0$, there exists a rather simple uniform search algorithm which is $O( \log^{1+ε} k)$-competitive. In addition, we give a lower bound for the setting in which agents are given some estimation of k. As a special case, this lower bound implies that for any constant $ε\textgreater{} 0$, if each agent is given a (one-sided) $k^ε$-approximation to k, then the competitiveness is $Ω$(log k). Informally, our results imply that the agents can potentially perform well without any knowledge of their total number k, however, to further improve, they must be given a relatively good approximation of k. Finally, we propose a uniform algorithm that is both efficient and extremely simple suggesting its relevance for actual biological scenarios.
Denaturing nature : philosophical and historical reflections on the artificial-natural distinction in the life sciences
Creators: name: Inkpen, S. Andrew
Publisher: name: University of British Columbia
Year: 2014

description: The philosopher Georges Canguilhem observed that the “physician’s thought and activity are incomprehensible without the concepts of the normal and the pathological.” I argue similarly regarding the biologist, only it is “the artificial” and “the natural” that are indispensable. Whether it is their objects of study, the methods used to investigate those objects, or even fellow researchers, biologists have habitually classified aspects of their discipline in a way that reflects the artificial-natural distinction. Why this way of classifying? What purpose does it serve? What principles guide its application? With what repercussions? Tracing the transformation of these concepts through a series of historical episodes, I explore the reasons why biologists use this distinction and how it has influenced the practices and directions of certain biological fields—specifically evolutionary biology and ecology. The argument of this dissertation is that in biology decisions concerning the choice and evaluation of experimental and evidential practices, objects of study, and even assessments of scientific personas betray the artificial-natural distinction. Invocations of this distinction, like the normal-pathological, code normative contentions about proper biological practice. “The natural,” I argue, often functions as an epistemic authority. The methodology I employ in this dissertation is conceptual and historical. The arguments marshalled are supported by conceptual-philosophical analysis, close readings of primary texts, and archival work. In the end I aim to problematize a set of widely invoked, but heterogeneously used, biological concepts. My arguments undermine a commonplace view according to which the collapse of the artificial-natural distinction is a prerequisite for contemporary science. This distinction is not, I argue, an outdated, pernicious relic; it has continued to exert a significant influence on scientific practice, and should not be ignored.
DA “I CLASSICI IN DIALETTO” AI “CLASSICI DEL DIALETTO” NELLA MANUALISTICA SCOLASTICA E POPOLARE TRA IL 1861 E IL 1930

description: L’intervento intende mettere in luce il rapporto tra i classici e il dialetto nella manualistica scolastica e popolare tra il 1861 e il 1930. In particolare, dalla disamina del corpus di testi raccolto per l’intervento, raffrontato con gli studi esistenti sull’argomento, si intende mostrare l’evoluzione del binomio classico-dialetto nel suddetto arco cronologico. Nel secondo Ottocento le versioni dialettali della Commedia dantesca e le versioni di alcuni passi dei classici greci e latini sono accomunate da un generico scopo pedagogico e istruttivo; inoltre, costituiscono il primo passo per una nobilitazione riflessa dei vernacoli (in particolare di quelli che non possono vantare una solida tradizione letteraria) tramite il confronto con i classiciper eccellenza. Questa fase è propedeutica al ribaltamento di prospettiva, nel rapporto italiano-dialetti, avvenuto negli anni Venti del Novecento, quando è incentivata la costituzione di un canone della letteratura orale popolare e dialettale. Negli eserciziari impostati sul metodo comparatistico è l’italiano a doversi misurare col potenziale espressivo dei vernacoli, tanto delle future Fiabe italiane, quanto dei classici dialettali già consacrati.

From “classics in dialect” to “classics of dialect” in school and popular manuals between 1861 and 1930

This paper highlight the relationship between the classics and dialect in school and popular manuals between 1861 and 1930. In particular, from the examination of the corpus of texts collected, compared with the existing studies on the topic, we intend to show the evolution of the classical-dialect binomial in the aforementioned time period. In the second half of the nineteenth century, versions of Dante’s Commedia in dialect and some passages of Greek and Latin classics shared a generic pedagogical and instructive purpose; moreover, they constituted the first step in the refinement of the vernacular (in particular for those that did not have a solid literary tradition) through comparison with classics par excellence. This phase was propaedeutic to the reversal of perspective, in the Italian-Dialect relationship, which took place in the 1920s, when the establishment of a canon of popular and dialectal oral literature was encouraged. In a comparative light, Italian had to measure itself with the expressive potential of the vernacular, also for the future Italian Tales, which were already consecrated dialectal classics.

A complete view of complex chemistry in gas and ice using ALMA and JWST
Creators: name: Yang, Yao-Lun
Publisher: name: Zenodo

description: The discovery of complex organic molecules (COMs) in solar-type protostars highlights the extensive chemical evolution at the onset of planet formation.  These molecules, which are potential precursors to pre-biotic molecules, are also found in comets that contain the most pristine matter in the solar system.  In recent years, the increasing detection of COMs by ALMA suggests a common presence of COMs in the early stage of star formation.  However, the formation pathways of COMs and whether most protostars undergo similar chemical evolution remain open questions with incomplete observational constraints.  It is thought that COMs form in the ice mantles on dust grains followed by thermal sublimation near protostars, but direct observational constraints are scarce.  While ALMA provides sub-100 au resolution, a resolution necessary to resolve sites of planet formation, to characterize gaseous COMs in nearby embedded protostars, measurements of chemical composition in ices had been limited by low-resolution and limited sensitivity spectroscopy until JWST.  Thus, it is imperative to probe both gas and ice chemistry related to COMs, which can only be achieved with both ALMA and JWST.  In this presentation, I show the results of gas+ice chemical analysis in a Class 0 protostar, IRAS 15398-3359, using multi-configurations ALMA observations and the JWST CORINOS program, latter of which shows potential signatures of icy COMs.  I also present an overview of the ice chemistry characterized by the JWST CORINOS program.
Strong existence and uniqueness for stochastic differential equation with H{ö}lder drift and degenerate noise
Creators: name: de Raynal, Paul-Eric Chaudru
Publisher: name: arXiv
Year: 2012
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: In this paper, we prove pathwise uniqueness for stochastic degenerate systems with a H{ö}lder drift, for a H{ö}lder exponent larger than the critical value 2/3. This work extends to the degenerate setting the earlier results obtained by Zvonkin, Veretennikov, Krylov and R{ö}ckner from non-degenerate to degenerate cases. The existence of a threshold for the H{ö}lder exponent in the degenerate case may be understood as the price to pay to balance the degeneracy of the noise. Our proof relies on regularization properties of the associated PDE, which is degenerate in the current framework and is based on a parametrix method.

description: Representing graphs as quantum states is becoming an increasingly important approach to study entanglement of mixed states, alternate to the standard linear algebraic density matrix-based approach of study. In this paper, we propose a general weighted directed graph framework for investigating properties of a large class of quantum states which are defined by three types of Laplacian matrices associated with such graphs. We generalize the standard framework of defining density matrices from simple connected graphs to density matrices using both combinatorial and signless Laplacian matrices associated with weighted directed graphs with complex edge weights and with/without self-loops. We also introduce a new notion of Laplacian matrix, which we call signed Laplacian matrix associated with such graphs. We produce necessary and/or sufficient conditions for such graphs to correspond to pure and mixed quantum states. Using these criteria, we finally determine the graphs whose corresponding density matrices represent entangled pure states which are well known and important for quantum computation applications. We observe that all these entangled pure states share a common combinatorial structure.

description: This year also marks the tenth anniversary of the VLBI effort at ALMA, so it is timely to review what has been accomplished, where we are, and what the future is likely to have in store. The ALMA Phasing System (APS) is a complex one which we attempt to describe here, its . The scientific outcome together with GMVA and EHT is well known, but aside from the noteworthy supermassive black hole images, we have also made considerable advances making use of ALMA-only interferometric data mostly due to the long full-polarization session observations during VLBI campaigns. With the recent additions of spectral-line VLBI observations and ALMA-standalone Phased-Array observations, while the wide-band sensitivity upgrade is gaining momentum, we can only expect that a great future is ahead.

description: We derive some restrictions on the topology of a monotone Lagrangian submanifold $L\subset\mathbf{C}^n$ by making observations about the topology of the moduli space of Maslov 2 holomorphic discs with boundary on $L$ and then using Damian's theorem which gives conditions under which the evaluation map from this moduli space to $L$ has nonzero degree. In particular we prove that an orientable 3-manifold admits a monotone Lagrangian embedding in $\mathbf{C}^3$ only if it is a product, which is a variation on a theorem of Fukaya. Finally we prove an h-principle for monotone Lagrangian immersions.

LA 'BATRACOMIOMACHIA' DI ALESSANDRO GARIONI TRA GRECO, ITALIANO E MILANESE
Creators: name: Sironi, Francesco
Publisher: name: Italiano LinguaDue
Year: 2019

description: Nel 1793 il domenicano Alessandro Garioni pubblicò a Milano un’edizione della Batracomiomachia corredata di traduzione letterale italiana e “parafrasi” poetica in milanese. Nell’introduzione, Garioni attribuisce con convinzione il poemetto ad Omero. In quest’ottica, si tratta dunque del primo tentativo di tradurre Omero in milanese. L’analisi di quest’opera e del suo rapporto con la letteratura precedente, erudita e non solo, si propone di collocarla nella storia della fortuna dei Classici e della letteratura milanese. In particolare, si evidenzia come la parafrasi milanese non possa considerarsi parodia del poemetto greco.

The ‘Battle of mice and frogs’ by Alessandro Garioni between greek, italian and milanese

In 1793 the Dominican monk Alessandro Garioni published an edition of the Battle of mice and frogs with a literal Italian translation and poetic “paraphrasing” in Milanese. In the introduction, Garioni ascribes the poem to Homer. In his view, this was the first attempt to translate Homer into Milanese. The analysis of the work and its relationship to earlier literature, both scholarly and not, aims to place it within the tradition of Classical and Milanese literature. In particular, it is noted that the paraphrasing in Milanese is not a parody of the Greek poem.

description: The Recreational Linguistics (Ludolinguistica) is a discipline which stimulates language learning through word games and lexical combinations. The pedagogical approach, created by da Anthony Mollica, is a “non-traditional” method to acquire linguistic and cultural skills. The method includes acrostics, mesostichs, tongue twisters, crossword puzzles, word searches, riddles, which Mollica advocates to teach language (vocabulary and grammar) as well as culture. “Motivate, amuse, teach” are the keywords suggested for ludolinguistica, a term which Nicola Zingarelli includes in his Vocabolario della lingua italiana in l998. The various pedagogical suggestions are aimed at providing a motivational tool in a relaxing environment for students learning another language or reinforcing the structures of their mother tongue.
