description: Questa Guida, destinata ai responsabili della politica migratoria degli Stati membri, interroga la nozione d’integrazione linguistica, registra i mezzi e descrive i passi indispensabili per affrontare questa problematica, in modo che i piani e i progetti elaborati dalle autorità pubbliche rispondano alle necessità ed alle attese sia della società d’accoglienza che dei migranti stessi. Questo può realizzarsi solo se vengono rispettati i valori condivisi del Consiglio d’Europa. Il documento descrive le risorse già messe a punto dal Consiglio d’Europa e propone, a partire da esempi concreti, delle linee guida per la progettazione di programmi di formazione. Si insiste sul fatto che il termine “migrante” non definisce un unico gruppo di individui a cui offrire un tipo di apprendimento uguale per tutti. Si sottolinea come i programmi di formazione debbano essere adattati alle necessità ed alle aspettative specifiche dei loro utenti. Scopo di questi programmi è anche quello di fare comprendere ai migranti che l’acquisizione di una nuova lingua non implica in nessun modo disconoscere le lingue da loro già acquisite. Infine la Guida si interroga sugli standard di qualità richiesti perché i test risultino affidabili e sull’eccessivo ruolo che è spesso loro attribuito.

Linguistic integration of adult migrants
Guide to policy development and implementation

Council of Europe

This Guide, designed for migration policy decision makers in the member states, addresses the notion of linguistic integration, surveys the means and describes the steps that are essential in addressing the issue in a way that enables the schemes set up by public authorities to meet the needs and expectations of both the host society and the migrants themselves. This can only be truly achieved if the common values of the Council of Europe are respected. The Guide outlines the resources already developed by the Council of Europe and proposes guidelines for designing training programmes based on concrete examples. The term “migrant” does not define a single group of people requiring a single type of training and the Guide emphasises that training programmes must be tailored to meet the needs and expectations of those they cater for. It is also their duty to make it clear to migrants that learning a new language in no way implies that they have to turn their backs on the languages they already know. Finally, the book discusses the quality standards required for reliable testing and the very excessive role which it is often attributed.

description: Σκοπός της διατριβής ήταν η ιστορική τεκμηρίωση, η γεωμετρική αποτύπωση και η αποτίμηση της φέρουσας ικανότητας της γέφυρας Κονδύλη που βρίσκεται στην κω-μόπολη Πύλη, στο νομό Τρικάλων. Η γέφυρα Κονδύλη κατασκευάστηκε το 1936 και είναι μία από τις πρώτες γέφυρες, κατασκευασμένες από οπλισμένο σκυρόδεμα, στην Ελλάδα. Εξετάσαμε το ιστορικό της γέφυρας από την κατασκευή τής, έως σήμερα. Συντάξαμε αναλυτικά αρχιτεκτονικά σχέδια όψεων, κατόψεων και τομών του δομή-ματος και αναλύσαμε την κατασκευαστική του δομή. Καταγράψαμε την παθολογία της γέφυρας, όσον αφορά τις βλάβες που εμφανίζονται και τα αίτια που τις προκα-λούν. Για την αποτίμηση της φέρουσας ικανότητας της, καταστρώσαμε προσομοίωμα με το πρόγραμμα SAP2000 και λαμβάνοντας υπόψη τα κινητά φορτία που ορίζουν δύο κανονιστικά πλαίσια, ένα παλιότερο του 1982 (DIN1072) και ένα σύγχρονο του 2003 (Ευρωκώδικας 1), πραγματοποιήθηκε γραμμική ελαστική και δυναμική φασματική ανάλυση.

description: The aim of the present thesis was the study of the historical documentation, the geometric mapping and the assessment of the carrying capacity of the Kondylis bridge located in the town of Pyli, in the prefecture of Trikala. The Kondylis Bridge was built in 1936 and is one of the first bridges, made of reinforced concrete, in Greece. We have examined the bridge's history from its construction to the present day. We compiled detailed architectural drawings, floor plans and sections of the structure and analyzed its construction structure. We have recorded the pathology of the bridge in terms of the lesions they present and the causes that cause them. In addition, for the assessment of the load capacity, we have developed an analytical model of the carrier in the SAP2000 software, and taking into account the mobile loads that define two regulations, one older than 1982 (DIN1072) and one modern in 2003 (European Code 1), a linear elastic and dynamic analysis was performed. It followed the formation of all the components of the carrier and their adequacy factor was calculated
Global characteristics of GRBs observed with INTEGRAL and the inferred large population of low-luminosity GRBs

description: INTEGRAL has two sensitive gamma-ray instruments that have detected 46 gamma-ray bursts (GRBs) up to July 2007. We present the spectral, spatial, and temporal properties of the bursts in the INTEGRAL GRB catalogue using data from the imager, IBIS, and spectrometer, SPI. Spectral properties of the GRBs are determined using power-law, Band model and quasithermal model fits to the prompt emission. Spectral lags, i.e. the time delay in the arrival of low-energy gamma-rays with respect to high-energy gamma-rays, are measured for 31 of the GRBs. The photon index distribution of power-law fits to the prompt emission spectra is consistent with that obtained by Swift. The peak flux distribution shows that INTEGRAL detects proportionally more weak GRBs than Swift because of its higher sensitivity in a smaller field of view. The all-sky rate of GRBs above ~0.15 ph cm^-2 s^-1 is ~1400 yr^-1 in the fully coded field of view of IBIS. Two groups are identified in the spectral lag distribution, one with short lags <0.75 s (between 25-50 keV and 50-300 keV) and one with long lags >0.75 s. Most of the long-lag GRBs are inferred to have low redshifts because of their long spectral lags, their tendency to have low peak energies and their faint optical and X-ray afterglows. They are mainly observed in the direction of the supergalactic plane with a quadrupole moment of Q=-0.225+/-0.090 and hence reflect the local large-scale structure of the Universe. The rate of long-lag GRBs with inferred low luminosity is ~25% of Type Ib/c supernovae. Some of these bursts could be produced by the collapse of a massive star without a supernova or by a different progenitor, such as the merger of two white dwarfs or a white dwarf with a neutron star or black hole, possibly in the cluster environment without a host galaxy.

Research in progress: Cuban and Samaná Haitian as windows on Creole genesis
Creators: name: Jacobs, Bart
Publisher: name: JournaLIPP
Year: 2013

description: This paper provides the outlines of a postdoc project on two diasporic varieties of Haitian Creole, which is currently being carried out by the author at the Leiden University Centre for Linguistics. The project aims at documenting the Haitian Creole varieties spoken by Haitian migrants in Cuba and the Dominican Republic’s Samaná Peninsula. These two diasporic varieties have developed in relative isolation from Haiti and can thus be expected to be linguistically conservative. By documenting these varieties, the project strives to provide a window on the early stages of the development of Haitian Creole and, in doing so, to make a breakthrough in the ongoing debate on creole genesis, a debate in which Haitian Creole plays a pivotal role.

description: We study finite-size effects on the convergence time in a continuous-opinion dynamics model. In the model, each individual's opinion is represented by a real number on a finite interval, e.g., $[0,1]$, and a uniformly randomly chosen individual updates its opinion by partially mimicking the opinion of a uniformly randomly chosen neighbor. We numerically find that the characteristic time to the convergence increases as the system size increases according to a particular functional form in the case of lattice networks. In contrast, unless the individuals perfectly copy the opinion of their neighbors in each opinion updating, the convergence time is approximately independent of the system size in the case of regular random graphs, uncorrelated scale-free networks, and complete graphs. We also provide a mean-field analysis of the model to understand the case of the complete graph.

description: Iatrogenic factors play an important role in H. pylori eradication failure, whereas it can be easily missed. Therefore, we aimed to investigate and analyze these related iatrogenic factors of H. pylori eradication failure. A total of 508 patients who experienced H. pylori eradication failure were included in this study conducted from December 2019 to February 2022. All the patients filled out a questionnaire including demographic characteristics, duration of treatment, regimens, dosage, and time intervals in rescue treatment. In the first-line treatment, 89 patients (17.5%, 89/508) used at least one antibiotic with high resistance rate in triple therapy and 57 patients (11.2%, 57/508) used two antibiotics with high resistance rates or other not recommended antibiotics in quadruple therapy. In the rescue therapy, 85 regimens were repeatedly used as salvage regimens in 58 patients (22.6%, 58/257) and 178 regimens containing antibiotics with high resistance rates were repeatedly used in 85 patients (33.1%, 85/257). To decrease the risk of H. pylori eradication failure, iatrogenic factors need to gain more attention. Clinicians should enhance their education and training to standardize the treatment regimens, better manage the H. pylori infection, and improve the eradication rate eventually.
The policy cycle of polychlorinated biphenyls (PCBs) in Canada
Creators: name: Lee, Michael L.
Publisher: name: University of British Columbia
Year: 2008

description: This paper uses the case of Polychlorinated Biphenyls (PCBs) to examine the dynamics of the public policy cycle in Canada. A process approach is applied to examine the principal stages of the cycle: problem identification, agenda-setting, decision-making, and implementation. In examining these stages, the factors that drive the policy cycle and those that impede its progress are identified. The regulatory history of PCBs is traced to demonstrate some of the complexities of the policy cycle. As one of the better known hazardous wastes in Canada, PCBs have been the catalyst for the introduction of new toxic chemical regulations throughout the 1970s and 1980s. Since the late 1970s, regulatory policies have been developed and implemented for PCB use and handling. After major PCB accidents occurred during the second half of the 1980s, regulations were introduced for their transport, storage and disposal. This case study provides seven major conclusions: (1) before the right policy solution is found and implemented, several stages in the cycle may need to be repeated; (2) public perception is a key determinant of the policy problem; (3) focusing events are a critical factor in setting the agenda; (4) decision-making often takes an incremental approach due to incomplete information and divided policy jurisdictions; (5) successful implementation, particularly in divided jurisdictions, requires sympathetic officials who are supportive of the enabling legislation; (6) constituency group support is a necessary condition for policy implementation; and (7) to deal with public concerns which may impede the implementation process, officials need political and managerial skills.

description: The gap probabilities at the hard and soft edges of scaled random matrix ensembles with orthogonal symmetry are known in terms of $τ$-functions. Extending recent work relating to the soft edge, it is shown that these $τ$-functions, and their generalizations to contain a generating function parameter, can be expressed as Fredholm determinants. These same Fredholm determinants also occur in exact expressions for gap probabilities in scaled random matrix ensembles with unitary and symplectic symmetry.

description: We examine the transformation of noise under a quantum error correcting code (QECC) concatenated repeatedly with itself, by analyzing the effects of a quantum channel after each level of concatenation using recovery operators that are optimally adapted to use error syndrome information from the previous levels of the code. We use the Shannon entropy of these channels to estimate the thresholds of correctable noise for QECCs and find considerable improvements under this adaptive concatenation. Similar methods could be used to increase quantum fault tolerant thresholds.

What can be learned from a proto-neutron star's mass and radius?

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We make extensive numerical studies of masses and radii of proto-neutron stars during the first second after their birth in core-collapse supernova events. We use a quasi-static approach for the computation of proto-neutron star structure, built on parameterized entropy and electron fraction profiles, that are then evolved with neutrino cooling processes. We vary the equation of state of nuclear matter, the proto-neutron star mass and the parameters of the initial profiles, to take into account our ignorance of the supernova progenitor properties. We show that if masses and radii of a proto-neutron star can be determined in the first second after the birth, e.g. from gravitational wave emission, no information could be obtained on the corresponding cold neutron star and therefore on the cold nuclear equation of state. Similarly, it seems unlikely that any property of the proto-neutron star equation of state (hot and not beta-equilibrated) could be determined either, mostly due to the lack of information on the entropy, or equivalently temperature, distribution in such objects.

We derive absolute branching fractions for these decays, and also set a limit on the influence of a low mass CP-odd Higgs boson in the decay of the Upsilon(1S).

Prospects of newly detecting nearby star-forming galaxies by the Cherenkov Telescope Array

description: Prospects of the Cherenkov Telescope Array (CTA) for the study of very high energy gamma-ray emission from nearby star-forming galaxies are investigated. In the previous work, we constructed a model to calculate luminosity and energy spectrum of pion-decay gamma-ray emission produced by cosmic-ray interaction with the interstellar medium (ISM), from four physical quantities of galaxies [star formation rate (SFR), gas mass, stellar mass, and effective radius]. The model is in good agreement with the observed GeV--TeV emission of several nearby galaxies. Applying this model to nearby galaxies that are not yet detected in TeV (mainly from the KINGFISH catalog), their hadronic gamma-ray luminosities and spectra are predicted. We identify galaxies of the highest chance of detection by CTA, including NGC 5236, M33, NGC 6946, and IC 342. Concerning gamma-ray spectra, NGC 1482 is particularly interesting because our model predicts that this galaxy is close to the calorimetric limit and its gamma-ray spectral index in GeV--TeV is close to that of cosmic-ray protons injected into ISM. Therefore this galaxy may be detectable by CTA even though its GeV flux is below the {\it Fermi} Large Area Telescope sensitivity limit. In the TeV regime, most galaxies are not in the calorimetric limit, and the predicted TeV flux is lower than that assuming a simple relation between the TeV luminosity and SFR of M82 and NGC 253, typically by a factor of 15. This means that a more sophisticated model beyond the calorimetric limit assumption is necessary to study TeV emission from star-forming galaxies.

Paradigmatische Asymmetrie im altkirchenslavischen Passiv

description: Der folgende Artikel befasst sich mit dem altkirchenslavischen Passivsystem. Ausgangspunkt bildet die Frage, ob die beiden Verbformen, welche zur Bildung passiver Sätze verwendet werden konnten (reflexive Verben sowie analytische Bildungen mit passivem Partizip und Hilfsverb), tatsächlich gleichberechtigte Substituenten für griechische Passiva und daher beliebig gegeneinander austauschbar waren, oder ob ein parameterabhängiges Verteilungsmuster gefunden werden kann. Die sorgfältige Analyse aller im Codex Marianus enthaltenen Passivsätze zeigt, dass die beiden Bildungstypen im Präsens und im Aorist eine weitgehend komplementäre Verteilung aufweisen. Dies bestätigt die These, dass eine Kombination aus aspektuellen und temporalen Merkmalen ihre Distribution regulierte. Die minimale Überlappung im Funktionsbereich der reflexiven und analytischen Formen lässt darauf schließen, dass im AKS die ‘Arbeitsteilung’ zwischen ihnen schon relativ weit fortgeschritten, aber noch nicht vollständig abgeschlossen war.

description: I describe the dynamics in recently revealed phases with vector condensates of gauge fields in dense QCD (gluonic phase) and other gauge models. In this case, the Higgs mechanism is provided by condensates of gauge (or gauge plus scalar) fields. Because most of the initial symmetries in such systems are spontaneously broken, their dynamics is very rich. In particular, by using the Ginzburg-Landau approach, the existence of a gluonic phase with both the rotational symmetry and the electromagnetic U(1) being spontaneously broken was established. In other words, this phase describes an anisotropic superconductor. In the dual (confinement) description of this dynamics in dense two-flavor QCD, there are light exotic vector hadrons in the spectrum, some of which condense. There are also vortex-like and roton-like excitations in these phases.

description: Recent measurements of the temperature fluctuations of the cosmic microwave background (CMB) radiation from the WMAP satellite provide indication of a non-Gaussian behavior. Although the observed feature is small, it is detectable and analyzable. Indeed, the temperature distribution P^{CMB}(Delta T) of these data can be quite well fitted by the anomalous probability distribution emerging within nonextensive statistical mechanics, based on the entropy S_q = k (1 - \int dx [P(x)]^q)/(q - 1) (where in the limit case q -> 1 we obtain the Boltzmann-Gibbs entropy S_1 = - k \int dx P(x) ln[P(x)]). For the CMB frequencies analysed, ν= 40.7, 60.8, and 93.5 GHz, P^{CMB}(Delta T) is well described by P_q(Delta T) \propto 1/[1 + (q-1) B(ν) (Delta T)^2]^{1/(q-1)}, with q = 1.04 \pm 0.01, the strongest non-Gaussian contribution coming from the South-East sector of the celestial sphere. Moreover, Monte Carlo simulations exclude, at the 99% confidence level, P_1(Delta T) \propto e^{- B(ν) (Delta T)^2} to fit the three-year WMAP data.

description: Darstellungen des Althochdeutschen basieren oftmals auf teleologischen Vorannahmen. Anhand der Diskussion zweier Modelle, denen solche Perspektivierungen zugrunde liegen, zeigt dieser Artikel, wie hierbei die damalige Sprachrealität verzerrt dargestellt und ein Großteil der Überlieferung ausgeblendet wird. Konsequenzen daraus werden in der Althochdeutschen Grammatik sichtbar, wo u.a. die Graphien einiger Glossen auf Grund ihrer Abweichung von einer am Vorbild literarischer Texte gesetzten Norm abgewertet werden. Anhand der Griffelglossen im Freisinger Codex Clm 6300 wird gezeigt, dass derartige Graphien systematisiert und in diesem Beispiel erklärt werden können als Resultate nähesprachlicher Verschriftungsakte. Nimmt man derartige Überlieferungsquellen ernst, so liefern sie neue Einblicke in die soziokulturellen Kontexte der frühesten Verschriftung des Deutschen sowie in historische Sprachwandelprozesse.

description: Terahertz time-domain spectroscopy (THz TDS) is a well-known tool for material analysis in the terahertz frequency band. One crucial system component in every time-domain spectrometer is the delay line which is necessary to accomplish the sampling of the electric field over time. Despite the fact that most of the uncertainty sources in TDS have been discussed, the delay line uncertainty has not been considered in detail. We model the impact of delay line uncertainty on the acquired THz TDS data. Interferometric measurements of the delay line precision and THz time-domain data are used to validate the theoretical model.

description: In the standard model production of on-shell Z boson at a photon collider (or Z decays into $γγ$) is strictly forbidden by angular momentum conservation and Bose statistics (the Yang's Theorem). In the standard model with noncommutative space-time this process can occur. Therefore this process provides an important probe for the noncommutative space-time. The $γγ$ collision at the ILC by laser backscattering of the electron and positron beams offers an ideal place to carry out such a study. Assuming an integrated luminosity of 500 fb$^{-1}$, we show that the constraint which can be achieved on $Γ(Z\to γγ)$ is three to four orders of magnitude better than the current bound of $5.2\times 10^{-5}$ GeV. The noncommutative scale can be probed up to a few TeVs.

The innovation and adoption of English lexical blends
Creators: name: Connolly, Patrick
Publisher: name: JournaLIPP
Year: 2013

description: This article focuses on how innovation and adoption, two commonly-cited processes of language change, can be discerned in the emergence and spread of lexical blends. Lexical blending is a productive process in English by which parts of two lexemes are combined in order to create a new lexeme. Brunch, which is formed through the combination of parts of breakfast and lunch, is a typical example. This article describes an experiment which investigated the ways in which speakers assign meaning to unfamiliar blends. Participants were presented with a number of unfamiliar blends, some attested and some invented, and asked to cite their source lexemes and meanings. A number of hypotheses were tested: (1) where a majority of speakers agree on the source lexemes of an unfamiliar blend, they will also agree on its meaning (2) the higher the number of syllables in an unfamiliar blend, the more likely it is a consensus will be achieved with regard to its source lexemes; (3) where the unfamiliar blend rhymes with one of its source lexemes, the more likely it is a consensus will be achieved with regard to its source lexemes. I conclude with an attempt to relate these findings to the speaker’s involvement in broader processes of language change.

In vitro growth and genetic manipulation of hemopoietic repopulating cells

description: The adult bone marrow contains stem cells capable of reconstituting all hemopoietic lineages for the life-time of a recipient following lethal irradiation and bone marrow transplantation. Despite more than two decades of research to characterize this population of pluripotent stem cells, mechanisms that regulate the survival, proliferation and differentiation in the initial stages of hemopoietic development in vivo remain poorly understood. Methods for maintaining, expanding and following the fate of the most primitive hemopoietic cells in vitro thus offers major opportunities for the investigation into these mechanisms. The major objectives of this work were therefore initially to determine if totipotent stem cells capable of repopulating hemopoiesis in lethally irradiated mice could be maintained and proliferate for extended times in vitro, and subsequently to quantitate stem cell numbers in these cultures and assess their in vivo repopulating potential in lethally irradiated hosts. Initial studies were aimed at determining if stem cells capable of repopulating all hemopoietic lineages in lethally irradiated mice could be maintained and proliferate when grown in a long-term culture (LTC) system. Marrow cells from 5-fluorouracil treated male mice were infected with a helper-free recombinant virus carrying the neomycin resistance gene and seeded onto irradiated adherent layers of pre-established, long-term marrow cultures of female origin. At 4 weeks, cells from individual cultures were transplanted into multiple recipients. Southern blot analysis of hemopoietic tissues 45 days post transplant demonstrated large clonal populations common to lymphoid and myeloid tissues as indicated by the presence of unique retroviral insertion fragments. In a number of cases it was found that multiple recipients of a single flask were repopulated with the same clonally marked totipotent cells indicating expansion of such cells during culture prior to their injection into irradiated recipients. These results demonstrated for the first time both maintenance and expansion in vitro of totipotent stem cells with in vivo repopulating ability.

description: Estimating the contribution from axial-vector intermediate states to hadronic light-by-light scattering requires input on their transition form factors (TFFs). Due to the Landau-Yang theorem, any experiment sensitive to these TFFs needs to involve at least one virtual photon, which complicates their measurement. Phenomenologically, the situation is best for the $f_1(1285)$ resonance, for which information is available from $e^+e^-\to e^+e^- f_1$, $f_1\to 4π$, $f_1\to ργ$, $f_1\to ϕγ$, and $f_1\to e^+e^-$. We provide a comprehensive analysis of the $f_1$ TFFs in the framework of vector meson dominance, including short-distance constraints, to determine to which extent the three independent TFFs can be constrained from the available experimental input, a prerequisite for improved calculations of the axial-vector contribution to hadronic light-by-light scattering. In particular, we focus on the process $f_1\to e^+e^-$, evidence for which has been reported recently by SND for the first time, and discuss the impact that future improved measurements will have on the determination of the $f_1$ TFFs.

description: In this talk we review how a dilute gas of magnetic monopoles in the adjoint describes the spatial k-Wilson loops. We formulate an effective theory from $S_{MQCD}$ by integrating out dof's down to scales in between the magnetic screening mass and the string tension and relate the 3d pressure and the string tension. Lattice data are consistent with the gas being dilute for all temperatures.

description: The article reviews the physics of Anderson localization on random regular graphs (RRG) and its connections to many-body localization (MBL) in disordered interacting systems. Properties of eigenstate and energy level correlations in delocalized and localized phases, as well at criticality, are discussed. In the many-body part, models with short-range and power-law interactions are considered, as well as the quantum-dot model representing the limit of the "most long-range" interaction. Central themes -- which are common to the RRG and MBL problems -- include ergodicity of the delocalized phase, localized character of the critical point, strong finite-size effects, and fractal scaling of eigenstate correlations in the localized phase.
First-principles investigation of the electron-phonon interaction in OsN$_2$: Theoretical prediction of superconductivity mediated by N-N covalent bonds

description: A first-principles investigation of the electron-phonon interaction in the recently synthesized osmium dinitride (OsN$_2$) compound predicts that the material is a superconductor. Superconductivity in OsN$_2$ would originate from the stretching of covalently bonded dinitrogen units embedded in the transition-metal matrix, thus adding dinitrides to the class of superconductors containing covalently bonded light elements. The dinitrogen vibrations are strongly coupled to the electronic states at the Fermi level and generate narrow peaks in the Eliashberg spectral function $α^2F(ω)$. The total electron-phonon coupling of OsN$_2$ is $λ=0.37$ and the estimated superconducting temperature T$_c \approx 1$ K. We suggest that the superconducting temperature can be substantially increased by hole doping of the pristine compound and show that T$_c$ increases to 4 K with a doping concentration of 0.25 holes/OsN$_2$ unit.

Movierte Substantive als Prädikatsnomina in historischen und gegenwartsdeutschen Korpora

description: Dieser Aufsatz untersucht die Herausbildung und Gebrauchsbedingungen von Genuskongruenz bei prädikativ verwendeten femininen Substantivformen. Anhand kurzer historischer und gegenwartsdeutscher Korpusanalysen wird gezeigt, dass die ursprünglich vermutlich metaphorische Struktur im 19. Jh. erschienen ist und seit dem 20. Jh. immer mehr verbreitet wird. Aus heutiger Sicht kann trotzdem noch nicht von einer obligatorischen Genuskongruenz gesprochen werden, aber es können semantische und morpholexikalische Faktoren (höherer Grad an Lexikalisiertheit, nichtmetaphorische Verwendung, Ausdruck einer relativ stabilen Eigenschaft) gezeigt werden, die die Genuskongruenz bei Prädikatsnomina begünstigen.

UNO STUDIO DI CASO SULL’ELABORAZIONE E L’UTILIZZO DEL FEEDBACK  SCRITTO IN APPRENDENTI DI ITALIANO L2

description: Attraverso uno studio di caso che coinvolge due studentesse di italiano L2 di livello elementare/intermedio, si prendono in esame alcuni dei fattori che possono influire sull’utilizzo del feedback scritto da parte degli apprendenti. La raccolta dei dati si è svolta in tre giornate: nella prima le partecipanti hanno scritto un testo collaborativo a partire da una storia per immagini; nella seconda i testi, corretti con un intervento di feedback implicito, sono stati riconsegnati e la coppia ha prima analizzato le segnalazioni ricevute e poi riscritto il testo; nella terza le apprendenti hanno prodotto testi individuali a partire dallo stesso stimolo visivo. Oltre a confrontare le diverse stesure del testo, si analizzano le interazioni avvenute tra le apprendenti durante il lavoro di coppia finalizzato a utilizzare il feedback per produrre il secondo testo collaborativo. I risultati mostrano da un lato che un elevato livello di coinvolgimento nell’elaborazione del feedback non ne garantisce un utilizzo efficace, dall’altro che hanno un peso non trascurabile anche fattori più “personali” come le convinzioni sulla lingua bersaglio e l’atteggiamento nei confronti del lavoro di coppia.

A case study on the development and use of written feedback in Italian L2 learners

Through a case study involving two female elementary/intermediate Italian L2 students, we examine some of the factors that may affect the use of written feedback by the learners. Data collection took place over three days: on the first day, the participants wrote a collaborative text from a picture story; on the second the texts, corrected using implicit feedback, were returned, and the students first analyzed the reports received and then rewrote the text; on the third day the learners produced individual texts from the same visual stimulus. In addition to comparing the various drafts of the text, we analyzed the interactions between the learners during pair work aimed at using feedback to produce the second collaborative text. The results show, on the one hand, that a high level of involvement in interpreting the feedback does not guarantee efficient use. On the other, more “personal” factors, like beliefs about the target language and attitudes about pair work, have strong impact.
