    Peer review is one of the methods of problem-based learning, aimed at students conducting mutual assessment of written work in terms of their compliance with the structure of the study, as well as in content, style, punctuation, lexical and grammatical aspects, with a view to their further improvement taking into account the recommendations made. This method involves students to exchange brief informal comments as well as more detailed comments that contribute to improving the quality of their papers. In this paper, the author gives an analysis of the academic literature on the use of peer review in teaching foreign language writing. The analysis is presented on aspects to testify the didactic potential of the method. Every aspect is formulated as didactic function of peer review, under which the author understands the internal organization and regulation of the process of learning a foreign language on the basis of this method. As a result, the author proposes to include the following language didactic functions of peer review: a) the transfer of the share of responsibility for the result of mastering the educational material from the teacher to the students themselves; b) the role of the teacher / instructor is to monitor teaching and learning activities of pupils and students; c) the organization of students’ interaction in the course of performance of educational tasks; d) the creation of didactic conditions for increasing the amount of out of class work and its combination with the classroom activities; e) the creation of conditions for teaching students to recognize their own strengths and weaknesses; f) reduction of time for evaluation of students’ works. The article describes in detail each of their functions

    Optical measurements of mesospheric winds by Fabry‐Perot spectrometers, FPSs, at Mawson, 67.6°S 62.9°E, and Davis, 68.6°S 78.0°E, Antarctica are compared with similar measurements obtained using a spaced‐antenna MF radar at Davis. The FPSs observed the OH emission. Different analysis procedures, used to determine the mean wind, and amplitude and phase of the semidiurnal tide, have been compared. At these latitudes the diurnal tide is weak and the semi‐diurnal tide, although highly variable in amplitude, is usually the dominant periodicity. When comparing the amplitude and phase of the semidiurnal tide good agreement is obtained between measurements by the two instruments

    The 1.5-5-day eastward waves in the upper stratosphere-mesosphere as observed by the Esrange meteor radar and the SABER instrument

    Data of neutral meridional wind obtained by the meteor radar at Esrange and data of temperature and pressure measured by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on board the Thermosphere–Ionosphere–Mesosphere Energetics and Dynamics (TIMED) spacecraft were studied with respect to a day-to-day atmospheric variability with periods from 1.5 to 5 days. The detailed analysis was carried out for February 2004. Perturbations of the atmospheric parameters at the examined periods appeared mainly as eastward propagating waves of zonal wavenumbers 1 and 2. We suggested that these waves excited by the jet instability on both flanks of the polar night jet in the upper stratosphere and mesosphere interact non-linearly with each other, and this interaction generates secondary waves. The radar observed both primary and secondary waves at mesospheric heights. The data analysis supports this suggestion. Under conditions of weaker instability observed in February 2003 the perturbations of atmospheric parameters of periods from 1.5 to 5 days had smaller amplitudes at heights of the mesosphere than those in February 2004. It was found that the Eliassen-Palm fluxes calculated for the waves generated by the jet instability were mainly downward directed. This result suggests a possible dynamical influence of the mesospheric layers on the lower atmospheric levels

    Long-term variability of the mesosphere/lower thermosphere (lower E region ionosphere) since 1970 has been analyzed using wind data series obtained at Collm (52° N, 15° E) using the LF drift method and at Obninsk (55° N, 37° E) applying VHF meteor radar. Applying piecewise linear trend analysis with a priori unknown number and positions of breakpoints shows that trend models with breakpoints are generally to be preferred against straight lines. There is a strong indication for a change of trends in wind parameters around 1975–1980. Similar changes are also found in the lower atmosphere, e.g., in tropospheric temperatures. This indicates a coupling between atmospheric layers at time scales of decades

    Un capitolo della fortuna di Tasso in Russia: la traduzione della Gerusalemme Liberata di A.F. Merzljakov

    No full text
    Questa tesi intende approfondire la figura del poeta, critico e traduttore Aleksej Fëdorovič Merzljakov (1778‒1830), concentrandosi, in particolare, sulla sua traduzione della Gerusalemme liberata, a cui egli lavorò per vent’anni e che pubblicò nel 1828, solo due anni prima della sua prematura scomparsa. Personaggio aspramente criticato in Russia già negli ultimi anni della sua vita e presto relegato a un ruolo secondario nella storia della letteratura russa, Merzljakov è in realtà degno di essere studiato, poiché la sua opera, classicista con suggestioni sentimentali e romantiche, ben raffigura la varietà e anche le contraddizioni del panorama culturale nei primi trent’anni dell’Ottocento, periodo caratterizzato da accese dispute tra tendenze poetiche differenti che contribuirono tra l’altro allo sviluppo della lingua letteraria e dell’epica in Russia. Negli stessi anni in cui si sviluppò la carriera letteraria di Merzljakov, la figura di Torquato Tasso risultava centrale in Russia. Il tema della ricezione della Gerusalemme liberata in questo paese e delle sue traduzioni è da lungo tempo oggetto di interesse per gli studiosi. Tuttavia, nessuno si è ancora dedicato esclusivamente al rapporto tra Merzljakov e Tasso o all’esame della sua traduzione. La ragione di ciò è forse da ricercare, oltre che nel ruolo marginare cui l’autore russo fu relegato negli ultimi anni di vita, anche nello scarso successo della sua versione del poema, già criticata dalla quasi totalità dei suoi contemporanei del traduttore per lo stile eccessivamente arcaicizzante, troppo lontano dal linguaggio solenne ed elegante dell’originale italiano. Ciò ne ha decretato una fama in gran parte negativa e quasi l’oblio già pochi anni dopo la sua pubblicazione. Come si vedrà, le riflessioni sulla sua traduzione esposte in questo lavoro, che ne evidenziano alcuni tratti essenziali, portano a concordare sostanzialmente con le critiche sulla lingua e sullo stile avanzate dai contemporanei di Merzljakov. Malgrado ciò, la versione della Liberata di Merzljakov merita di essere studiata in quanto originale testimonianza della fortuna tassiana in Russia, che, come quasi tutta l’opera di Merzljakov, ricerca la ricerca dell’armonia e della grandiosità del Classicismo, contemperate da elementi già romantici. La tesi si articola in cinque capitoli.This thesis aims to delve into the figure of the poet, critic, and translator Aleksey Fyodorovich Merzlyakov (1778–1830), focusing on his translation of Torquato Tasso’s Jerusalem Delivered, which was published in 1828, just two years before his untimely death. Harshly criticized in Russia in the last years of his life and soon relegated to a secondary role in the history of Russian literature, Merzlyakov is indeed worthy of study. His work, combining Classicism with Sentimental and Romantic influences, effectively represents the variety and contradictions of the cultural landscape in the early decades of the 19th century. This period was marked by heated disputes among different poetic trends, contributing to the development of the literary language and epic in Russia. During the same years of Merzlyakov's literary career, the figure of Torquato Tasso was central in Russia. The topic of the reception of Jerusalem Delivered in Russia and its translations has long been of interest to scholars. However, no one has exclusively studied the relationship between Merzlyakov and Tasso or examined his translation yet. The reason could be the marginal role to which the Russian author was relegated in the last years of his life and the limited success of his version. Indeed, Merzlyakov’s translation was criticized by almost all his contemporaries for its excessively archaic style, too far from the solemn and elegant language of the source text, leading to a largely negative reputation and almost oblivion shortly after its publication. As this work will show, the analysis of his translation, highlighting some essential features, largely aligns with the critiques of the language and style made by Merzlyakov's contemporaries. Nevertheless, Merzlyakov's version of Jerusalem Delivered deserves study as it represents an original testimony to Tasso's influence in Russia, reflecting his quest for harmony and grandeur, which is a typical feature of Classicism, tempered by elements already romantic. The thesis is divided into five chapters

    International audienceResults from the analysis of MLT wind measurements at Dixon (73.5°N, 80°E), Esrange (68°N, 21°E), Castle Eaton (UK) (53°N, 2°W), and Obninsk (55°N, 37°E) during summer 2000 are presented in this paper. Using S-transform or wavelet analysis, quasi-two-day waves (QTDWs) are shown to appear simultaneously at high- and mid-latitudes and reveal themselves as several bursts of wave activity. At first this activity is preceded by a 51?53h wave with S=3 observed mainly at mid-latitudes. After a short recess (or quiet time interval for about 10 days near day 205), we observe a regular sequence of three bursts, the strongest of them corresponding to a QTDW with a period of 47?48h and S=4 at mid-altitudes. We hypothesize that these three bursts may be the result of constructive and destructive interference between several spectral components: a 47?48h component with S=4; a 60-h component with S=3; and a 80-h component with S=2. The magnitudes of the lower (higher) zonal wave-number components increase (decrease) with increasing latitude. The S-transform or wavelet analysis indicates when these spectral components create the wave activity bursts and gives a range of zonal wave numbers for observed bursts from about 4 to about 2 for mid- and high-latitudes. The main spectral component at Dixon and Esrange latitudes is the 60-h oscillation with S=3. The zonal wave numbers and frequencies of the observed spectral components hint at the possible occurrence of the nonlinear interaction between the primary QTDWs and other planetary waves. Using a simple 3-D nonlinear numerical model, we attempt to simulate some of the observed features and to explain them as a consequence of the nonlinear interaction between the primary 47?48h and the 9?10day waves, and the resulting linear superposition of primary and secondary waves. In addition to the QTDW bursts, we also infer forcing of the 4-day wave with S=2 and the 6?7day wave with S=1, possibly arising from nonlinear decoupling of the 60-h wave with S=3. The starting mechanism for this decoupling is the Rossby wave instability (e.g. Baines, 1976). This result is consistent with the day-to-day wind variability during the observed QTDW events. An interesting feature of the final stage of the observed QTDW activity in summer 2000 is the occurrence of strong 4?5 day waves with S=3. Key words.

    On the longitudinal structure of the transient day-to-day variation of the semidiurnal tide in the mid-latitude lower thermosphere ? I. Winter season

    International audienceThe longitudinal structure of the day-to-day variations of semidiurnal tide amplitudes is analysed based on coordinated mesosphere/lower thermosphere wind measurements at several stations during three winter campaigns. Possible excitation sources of these variations are discussed. Special attention is given to a nonlinear interaction between the semidiurnal tide and the day-to-day mean wind variations. Data processing includes the S-transform analysis which takes into account transient behaviour of secondary waves. It is shown that strong tidal modulations appear during a stratospheric warming and may be caused by aperiodic mean wind variations during this event.Key words.
