Dissertations / Theses on the topic 'The Pashto Language'

The purpose of this paper is to examine potential similarities in Hindi1 and Pashto grammar as regards to the arial feature of lexical reduplication, and to give a brief explanation of the phenomenon. It is my belief that this feature appears in both languages and that it functions in a similar way when it comes to: full reduplication, distribution and partial reduplication, so called echo-words. I will try to explain how these features function in Pashto based on the research already done in Hindi and the limited amount of description found in Pashto grammars that discuss this subject. The object of the paper is to prove that reduplication in Pashto takes similar form with similar meaning to the reduplications found in Hindi. To analyse this I will look at literary language in Hindi and Pashto using examples found in books, grammars, papers of other researchers, as well as examples found online in blogs and on newspaper sites. The first section of this paper will deal with full reduplication of nouns, pronouns, adjectives and adverbials, numerals and participles. It will show that various types of semantic meanings can be derived from reduplication such as intensification, attenuation, continuation or distribution. The second section will deal with partial reduplication and it will show that these also appears in the different word categories mentioned (though apparently not in both languages) and it aims to give an explanation as to what forms these partial reduplications can take, that is, how they are constructed, as well as how they may function.

Le pashto, langue iranienne du nord-est parlee en afghanistan et au pakistan par environ quinze millions de locuteurs, se repartit en trois grandes aires dialectales: a(orientale), b(centrale), c(occidentale). Cette division repose essentiellement sur des criteres phonologiques. Une mutation vocalique : la metaphonie "waziri", se retrouve toute entiere dans la zone b. Cette etude s'attache a la description d'un parler pashto de la zone centrale, le parler des ethnies "djadran" et "tani" (paktya, afghanistan), dans lequel la metaphonie waziri est complete. La premiere partie est consacree a la phonologie : le trait le plus saillant en est la reduction du systeme vocalique : cinq voyelles, pas d'oppositions de quantite. La seconde partie, qui concerne le verbe, est le centre de la description. Les verbes se repartissent en deux grandes classes : les verbes simples et les verbes composes. Ils ne sauraient etre confondus : les verbes simples forment leur perfectif par prefixation d'un morpheme ; les verbes composes excluent ce morpheme, mais leur base en possede toutes les proprietes (accentuelles et tactiques). Verbes simples et verbes composes sont a distinguer des locutions verbales. La transcription s'efforce d'integrer ces donnees par l'usage de quelques signes conventionnels. Suit une presentation de la valeur des formes. Une place particuliere est accordee a la categorie de l'eventuel et aux relations entre imperatif et injonctif. La troisieme partie est consacree aux mots pronominaux. La quatrieme partie est consacree a la flexion du nom et a celle de l'adjectif. La cinquieme partie traite de diverses particules : relateurs, adverbes, etc. La sixieme partie est une esquisse rapide de l'ordre des termes dans le groupe verbal : c'est-a-dire des diverses combinaisons du verbe avec d'une part des particules clitiques, d'autre part des particules accentogenes. Dans un second tome sont presentes (transcrits et traduits) deux textes du repertoire traditionnel : l'histoire de sayf ol-molouk (at 400) et celle des quatre compagnons (at 976 a - at 503 - at 916). Suit un glossaire du parler d'environ seize cents entrees<br>Pashto is a north-eastern iranian language spoken in afghanistan and in pakistan by about fifteen million speakers. It is divided into three great dialectological areas : a (east), b (central), c (west). This classification basically implies phonological criteria. A vowel change : the "waziri metaphony" is entirely found in zone b. The object of this study is the description of a variety of pashto in which the "waziri metaphony" is fully represented. This language is spoken by the "djadran" and the "tani" tribes (paktya, afghanistan). In the first volume a grammatical description will be found. In the second volume, we will present two folk stories (these stories are transcribed and translated) : the story of "sayf ol-molouk" (at 400) and the story of "the four friends" (at 976 - at 503 - at 916). In addition we will provid a glossary of this dialect

L ‘objectif poursuivi est de montrer que l'opposition du Pasado Compuesto au Pasado simple repose sur celle, modale, qui émerge de la structuration des énoncés. Dans cette hypothèse, on essaie d'aboutir à une caractérisation modo-aspectuelle des prédications d'existence intégrant chacune des formes en question. Le traitement de ce problème doit beaucoup aux outils élaborés par l'actuelle de formalisation de A. Culioli. Les indications de référence temporelle fournies par le pasado compuesto et le pasado simple font néanmoins apparaître que cette formalisation repose sur une sérieuse interversion des valeurs concernant la définition des repères qui fondent la construction de la "situation de co-énonciation" d'un côté, la construction des situations aoristiques, d'un autre côté. Ces problèmes sont au travail dans la totalité de la thèse. En ce qui concerne le pasado compuesto, on montre la profonde contingence des prédications qui sont de son ressort, à travers l'étude des zones d'indifférenciation qualitative et ou quantitative rattachées à la présence de marqueurs syntaxiques co-occurrents. On analyse les répercussions de ce phénomène au plan de la relation intersujets. A travers le concept de quantification des procès (interessant les déterminateurs de l'objet syntaxique), on aborde la question des déterminateurs aspectuelles concernant la distinction classique de "l'entier pas entier" (perfectif imperfectif). Avec le pasado simple seul, il est question de "prédication de conformité" et d'une caractérisation modale de type "nécessaire" de la relation "procès-objet. La totalité de ces conclusions se fonde sur l'analyse d'un corpus d'énoncés attestés<br>The objective pursued is to that opposition of the pasado compuesto to the pasado simple is based on a modal opposition which emerges from the structure of the utterances. Using this as hypothesis we try to arrive at a modal-aspectual characterisation of the predication of existence concerning the forms in question. The treatement of this problem owers much to the technical implements developped by formalisation team of a culioli. The indications of temporal reference furnished by the pasado. Compuesto and the pasado simple reveal nontheless that this formalisation is based on a serious interversion of the concerning the definition of "locators" are founded the construction of the enonciative situation, on the hand, and that of the aorist situations, on the other hand. As regards the pasado compuesto, we show the profound contingency of the predication of existence which this form introduces, throug studvng the qualitative and quantitative zones of indifferenciation attached to the presence of co-occurring syntatic markers we analyse the repercussions of this phenomenon on the level of inter-subject relations. Using the concept of quantification of processus (concerning the determinartion of the syntactic object. We approch the classic distinction of "entire non-entre" (perfective imperfective). With the pasado simple alone, it is a question of "predication of conformity" and a modal characterisation of "necessardy" type o the "process-object" relationship

U disertaciji je izvr&scaron;ena voltametrijska karakterizacija i određivanje pet&nbsp;neonikotinoidnih insekticida (imidakloprida, tiametoksama, klotianidina, nitenpirama i&nbsp;acetamiprida) na različitim elektrodama na bazi ugljenika, kao &scaron;to su elektroda od&nbsp;ugljenične paste, elektroda od staklastog ugljenika i bizmut-filmom modifikovani&nbsp;staklasti ugljenik. Pored ispitivanja u model-rastvorima, razvijene visokoosetljive&nbsp;diferencijalne pulsne voltametrijskemetode su primenjene za određivanje neonikotinoida&nbsp;u realnim uzorcima. Neonikotinoidi su određivani u uzorcima rečne vode i komercijalnim&nbsp;formulacijama, a praćena je i njihova fotolitička i fotokatalitička razgradnja. Radi&nbsp;potvrđivanja voltametrijskih rezultata, izvedena su komparativna merenja uz primenu&nbsp;tečne hromatografije sa detektorom od niza dioda i infracrvenespektrometrije. Detekcija&nbsp;pojedinih degradacionih proizvoda nastalih u toku ispitivanih fotodegradacionih procesa&nbsp;je praćena tečnohromatografskom metodom sa tandemskom masenospektrometrijskom&nbsp;detekcijom. Proučavana je povr&scaron;inska struktura CR 5 grafitnog praha, elektrode od&nbsp;ugljenične paste na bazi trikrezil-fosfata i elektrode od staklastog ugljenika pomoću&nbsp;skenirajuće elektronske mikroskopije.<br>This thesis is concerned with the voltammetric characterization and&nbsp;determination of five neonicotinoid insecticides (imidacloprid, thiamethoxam,&nbsp;clothianidin, nitenpyram and acetamiprid) at different carbon-based electrodes such as&nbsp;carbon paste, glassy carbon and bismuth-film modified glassycarbon. In addition to the&nbsp;investigations in model solutions, the developed highly sensitive differential pulse&nbsp;voltammetric methods were applied for the determination of neonicotinoids in real&nbsp;samples. Neonicotinoids were determined in river water samples, commercial&nbsp;formulations, and their photolytic and photocatalytic degradation was also monitored. To&nbsp;confirm the voltammetric results, comparative measurements were performed by liquid&nbsp;chromatography with diode-array detector and infrared spectrometry. Detection of some&nbsp;degradation products formed during the photodegradation processes was monitored using&nbsp;liquid chromatography with tandem mass-spectrometric detection. The surface structure&nbsp;of CR 5 graphite powder, tricresyl phosphate-based carbon paste electrode and glassy&nbsp;carbon electrode was investigated by scanning electron microscopy.

The Hindu Kush region stretches from Afghanistan over Pakistan to North India and is home to what is commonly known as the Dardic languages. The Dardic langagues are a group of Indo-Aryan languages that have in isolation and under contact developed or retained features that can not be found in Indo-Aryan languages outside the region. In the ongoing project ”Language contact and relatedness in the Hindu Kush region” data on over 50 languages has been collected including nine varieties of northwest Indo-Aryan Pashai spoken in west Afghanistan. A cognate analysis and an analysis of phonological, morphological, syntactical and lexical features were conducted. The cognate analysis shows that the Pashai varieties build two clusters, a western group consisting of the three western Pashai varieties and an eastern group consisting of six eastern varieties. The structural analysis shows a more diverse picture with three potential clusters, a group of the two most western varieties, a northeastern group and a central group consisting of one western variety and two southeastern varieties. Some features found to be shared by languages in the region are also found in all Pashai varieties like a subject-object-verb order and postpositions.<br>Hindukushregionen sträcker sig från Afghanistan över Pakistan till norra Indien och hyser de vanligtvis så kallade dardiska språken. De dardiska språken tillhör de indo-ariska språken vilka i isolation och genom kontakt utvecklade eller bevarade drag som inte längre finns i indo-ariska språk utanför regionen. I det pågående projekt “Språkkontakt och språksläktskap i Hindukushregionen” samlades data från mer än 50 språk inklusive nio varietéer av det nordvästra indo-ariska språket Pashai som talas i västra Afghanistan. En kognatanalys och en analys av fonologiska, morfologiska, syntaktiska och lexikala drag genomfördes. Kognatanalysen visar att Pashai varieteterna formar kluster, en västragrupp av de tre västra varieteterna och en östra grupp av de sex östra varieteterna. Struktruanalysen visar en mer skiftande bild av tre potentiella kluster, en grupp av de två mest västra varieteterna, en nordöstra grupp och en centergrupp bestående av en västra varietet och två sydöstra varieteter. Några drag som anses vara delad av språken i regionen kan också konstateras i alla Pashaivarieteter som ensubjekt-objekt-verb följd och postpositioner.

Although Andrew Marvell wrote and published relatively little, his poetry collects from the full range of “schools” and idiosyncratic styles present in the seventeenth century: echoes of Herbert, Donne, Milton, Traherne, Herrick, Lovelace, and Jonson, among others, permeate throughout his work. Although much of his imagery seems novel, if not strange, it is clear that Marvell has a deep engagement with several important long-running traditions. His work is conversation with Ovid, Horace, and Theocritus as much as it responds directly to the poets whose lives overlapped with his own. In his engagement with such varied sources, Marvell demonstrates an astounding degree of poetic flexibility. He is a master of imitating voice and style.

Pastor Pete Peters is a minister in La Porte, Colorado. He operates a small church, an Internet website, a newsletter, and a worldwide cassette tape ministry. He teaches Christian Identity, the belief that the white race is Israel of the Bible. His rhetoric contains open derision of Jews, homosexuals, and racial minorities, although he never openly advocates violence toward any group. After tracing the roots of the Christian Identity movement and reviewing the literature on the movement, this thesis examines Peters' rhetoric at the metaphoric level, analyzing the metaphors in four of Peters' key works for their underlying meaning. Metaphoric criticism as a method of rhetorical analysis is introduced and then applied to the metaphors extracted from America the Conquered, Baal Worship, The Greatest Love Story Never Told, and Whores Galore. These books, all by Peters, employ his metaphor of Jews corrupting the United States government and attempting to destroy white Christians through media, courts, and banking, of which Peters asserts they control. Through extracting and analyzing the metaphors in the four books, it was found that Peters does more than warn against corrupt systems: through metaphor and Biblical parallels, he subversively condones and nearly commands violence against Jews, homosexuals, and the government.

Past tense verb production in children with specific language impairment and language-matched children with typical language was compared using language samples and a standardized probe (Rice/Wexler Test of Early Grammatical Impairment). Analyses revealed accuracy and error type differences between elicitation types and groups. Results have important clinical practice implications.

The goal of this thesis is to investigate whether and in which respect self-repairs can provide information on how non-native speakers of Spanish acquire regular and irregular past tense verb forms. According to Pinker and Prince's (1988, 1992) 'Dual Mechanism model' regular and irregular forms are not represented the same way in the speakers' mind: regular forms are computational, i.e. they respond to rule-governed mechanisms (as in look-ed, walk-ed). On the other hand, irregular forms are vocabulary items which are concatenated in the lexicon as one-piece units (as in the case of went, spoke). In this thesis we investigate whether this proposal is also valid in the case of Spanish past tense verb forms. Spanish verbs, unlike English verbs, are highly inflected and irregular forms not only have an irregular stem but they also have person, number, tense and aspect morphemes. By analysing the oral production of Spanish learners with different ages and from different learning environments, we have tried to contribute to the debate around the so-called 'Dual Mechanism' model.

U okviru disertacije ispitani su i upoređeni pokazatelji kvaliteta integralnog p&scaron;eničnog i integralnog heljdinog bra&scaron;na dobijenog mlevenjem netretiranih (netretirano integralno heljdino bra&scaron;no) i autoklaviranih zrna heljde (autoklavirano integralno heljdino bra&scaron;no). Nakon ispitivanja nutritivnih i funkcionalnih svojstava pomenutih bra&scaron;na, kreirane su i proizvedene integralne taljatele sa različitim sadržajem integralnog heljdinog bra&scaron;na (10&ndash;30%).Pokazatelji senzorskog, nutritivnog i funkcionalnog kvaliteta proizvedenih taljatela sa integralnim heljdinim bra&scaron;nima ispitani su u poređenju sa kontrolnim uzorkom taljatela od integralnog p&scaron;eničnog bra&scaron;na.U ispitivanim uzorcima bra&scaron;na i taljatela određeni su osnovni hemijski sastav, sadržaj mineralnih materija, sadržaj ukupnih rastvorljivih polifenola, utvrđen je kvalitativni i kvantitativni sastav polifenolnih jedinjenja, ispitana je antiradikalska aktivnost na DPPH˙ i određen je sadržaj fitinske kiseline i 5-hidroksimetilfurfural.Pored analize nutritivnih i funkcionalnih svojstava, na taljatelama su sprovedena ispitivanja fizičkih osobina (dimenzije) i svojstva taljatela pri kuvanju. Instrumentalno su izmereni boja i teksturna svojstva nekuvanih i kuvanih taljatela. Senzorska ocena taljatela sprovedena je uz primenu panela utreniranih ocenjivača, metodom bodovanja i panela potro&scaron;ača, testom dopadljivosti.Dobijeni rezultati ukazuju da se supstitucijom dela integralnog p&scaron;eničnog bra&scaron;na integralnim heljdinim bra&scaron;nom (autoklaviranim ili netretiranim) postiže unapređenje nutritivnog i funkcionalnog profila uzoraka obogaćenih taljatela, uz manje ili vi&scaron;e izraženo naru&scaron;avanje senzorskog profila, u zavisnosti od stepena supstitucije i vrste integralnog heljdinog bra&scaron;na.<br>This study investigated quality parameters of wholegrain wheat flour and wholegrain buckwheat flour from non-treated buckwheat grains (non-treated wholegrain buckwheat flour) and autoclaved buckwheat grains (autoclaved wholegrain buckwheat flour). After investigation of nutritional and functional properties of aforementioned flours, new wholegrain tagliatelle formulations, with different wholegrain buckwheat flour content (10&ndash;30%) have been developed.Sensory, nutritional and functional quality parameters of buckwheat containing tagliatelle samples were analysed and compared with control tagliatelle sample from wholegrain wheat flour.Proximate composition, content of minerals, content of total polyphenols and quantitative and qualitative composition of polyphenols were investigated in both, flour samples and produced uncooked and cooked tagliatelle samples. Antiradical activity on DPPH radicals, and content of less favourable compounds, phytic acid and HMF, have been tested, as well.Tagliatelle physical properties, dimensions, cooking properties, colour and textural properties were determined by instrumental and sensory methods. Tagliatelle acceptability was evaluated by the consumers. The obtained results indicate that wholegrain buckwheat flour (autoclaved or non-treated) incorporation into tagliatelle formulation led to an improvement of nutritional and functional profiles of tagliatelle samples, followed by greater or lesser deterioaration of sensory profile, depending on substitution level and type of wholegrain buckwheat flour.

Le présent travail est une petite recherche sur l'apprentissage du français, et plus particulièrement sur l'alternance de l'imparfait et le passé composé parmi des suédophones. Le but du mémoire est de comprendre comment les apprenants appliquent la grammaire malgré la différence entre leur langue maternelle et la langue de l'apprentissage. L'étude part de la différence entre le français et le suédois. Le corpus se compose de dix récits au passé écrits par des étudiants des niveau trois et quatre du système scolaire suédois. Le titre de leur devoir était Un souvenir de mon enfance. Un exercice pris du manuel est aussi analysé. Le résultat montre que d'abord les suédophones apprennent à utiliser les verbes d'état à l'imparfait, puis les suédophones expérimentent avec l'aspect des verbes pour l’alternance entre l’imparfait et le passé composé En conclusion, l'alternance entre l'imparfait et le passé composé est un défi pour les suédophones, mais ce n'est pas un défi insurmontable.<br>The current piece of research is a study of how second language learners adapt to the distinction between imperfect and perfect in the narrative of past in the French language. The aim of the study is to find out how the learners adopt the grammar despite the difference between their native language and their learning language. The study describes the difference between Swedish and French. The corpus is defined, consisting of ten narratives by ten second language learners on the levels three and four in the Swedish school system. The title was Un souvenir de mon enfance. An exercise in the schoolbook is also analysed. The result shows that the students first learn how to use imperfect in sentences containing a state verb. Later the students attempt the aspect of the verb to practise the shift between the past tense and the perfect tense. In conclusion, the shift between perfect and imperfect is a challenge to the Swedish learner. However, it is not an unbridgeable gap.

O presente estudo objetivou analisar a legitimação do poder entre franqueados da rede CCAA na região de Passo Fundo/RS; trata-se de um processo pelo qual esses pequenos empreendedores buscam consolidar suas relações de trabalho para exercerem suas funções de direção com autoconfiança. Para tanto, foi realizada uma pesquisa qualitativa descritiva que usou como método de coleta de dados a entrevista semi-estruturada aliada a observações do ambiente. Quatro diretores de escolas de idiomas da rede CCAA na região norte do estado do Rio Grande do Sul participaram da pesquisa. Os dados coletados foram submetidos a uma análise interpretativa feita a luz do referencial teórico que resgatou a conceituação do poder, bem como seu papel na sociedade, antes de abordar o poder (e suas fontes) no contexto das organizações empresariais. O manual de gestão de pessoas da rede CCAA permitiu que uma análise documental complementasse o estudo, cujos resultados ratificaram a difícil mensuração da legitimação do poder, mas foram positivos, no sentido de que o fenômeno foi investigado dos mais diversos ângulos e identificou-se de forma não-planejada uma série de fatores correlatos, provocando, assim, uma evolução no seu entendimento, pois percebeu-se que diferentes estratégias de legitimação do poder foram adotadas variando conforme a história de vida e o estilo de liderança de cada um dos empreendedores e que essas estratégias geraram resultados semelhantes a curto prazo, mas no longo prazo, tendem a distanciar as empresas em quesitos como grau de profissionalização e capacidade de expansão, por exemplo.<br>The current study had the purpose of analyzing the legitimation of power among directors of CCAA chain units in the region of Passo Fundo/RS, it´s a process in which these small business people try to make working relationships solid to perform their functions of direction with self-confidence. For so, it was done a descriptive qualitative research that used as method of data collection a semi-structured interview together with observations of the environment. Four directors of foreign languages schools of CCAA chain in the northern region of the state of Rio Grande do Sul took part in the research. The collected data were submitted to an interpretative analysis made under the light of the academic frame that rescued the conception of power, as well as its role in the society, before approaching the power (and its fountains) in the context of business organizations. The guidebook of people management of CCAA chain allowed a documental analysis to complement the study, which results reinforced the difficulties in measuring the legitimation of power, but were good after all, since the phenomena was investigated from an array of angles and a series of related factors were identified in a non-planned way, provoking, thus, an evolution on its understanding, since it was realized that different strategies of legitimation of the power were adopted according to the history of life and leadership style of each of the directors and that these strategies may create similar results in short term, but in long term tend to increase the distance between the companies in matters such as professionalization level or capacity for expansion, for instance.

This document examines the performance practices of the chorales in Johann Sebastian Bach's (1685-1750) Passio secundum Johannem, BWV 245. While many modern-day scholars and performers believe that the congregation sang the Passion chorales and therefore perform them in an accordingly straightforward and homogenous manner, my involvement with this work has led me to consider other possibilities of performance. I am convinced by the evidence in the Ordnungen und Gesetze der Schola Thomana (Regulations and Legislations of the Thomas School), the evidence presented by three renowned Bach scholars, and the evidence of Bach’s music, that the congregation would not have sung the chorales of the Passion. Having scrutinized the musical language and text that Bach deliberately and thoughtfully laid out, I see the possibility for a more dramatic and contextualized approach to these chorales, something the congregation would not and could not have achieved. Because there is almost no published scholarship regarding the performance practice of Passion chorales, there is a need for a study of this nature. My goal is to provide conductors and performers with a historically-informed option to present Bach's chorales in a manner that reflects the drama of the Passion story. I will demonstrate that conductors should consider factors such as harmonic language, textual interpretation, and placement within the broader Passion narrative when making interpretive performance decisions for each of the twelve chorales.

Danas, u raznim analitičkim laboratorijama postoji veći broj analitičkih protokola,zasnovanih bilo na izuzetno sofisticiranim ili jednostavnijim tehnikama, koji služe zaodređivanje različitih ciljnih analita od farmakolo&scaron;kog značaja. Među tim grupama ciljnih analita pripadaju i antibiotici koji predstavljaju veliko otkriće u oblasti medicine i zahvaljujući njima spa&scaron;eno je vi&scaron;e od sedam miliona života, ali pored navedenih koristi, antibiotici mogu da izazovu&nbsp; veliki broj neželjenih efekata i žučne kiseline zajedno sa svojim derivatima, koji su fiziolo&scaron;ki deterdženti, mogu biti citotoksične za organizam ako se njihova koncentracija ne kontroli&scaron;e. U ovoj doktorskoj disertaciji prikazan je razvoj analitičkih metoda pre svega voltametrijskihmetoda u kombinaciji sa jednostavnim i savremenim elektrodama/senzorima za određivanje&nbsp; odabranih analita kao &scaron;to je antraciklični antibiotik doksorubicin (DOX), makrolidni antibioticieritromicin-etilsukcinata (EES), azitromicina (AZI), klaritromicina (CLA) i roksitromicina&nbsp; (ROX) i 3-dehidro-deoksiholne kiseline.Voltametrijska karakterizacija i određivanje gore navedenih antibiotika primenom obnovljive srebro-amalgam film elektrode (Hg(Ag)FE)rađena je direktnom katodnom&nbsp; voltametrijom sa pravougaonim talasima (SWV) i visoko osetljivom adsorptivnom voltametrijom sa pravougaonim talasima (SW-AdSV) u Briton-Robinson puferu, kao pomoćnom elektrolitu, obuhvatajući &scaron;irok opseg pH vrednosti. Odgovor DOX-a primenom&nbsp; Hg(Ag)FE&nbsp;praćen je u intervalu potencijala od -0,20 do -0,80 V.&nbsp; Za analizu tragova, optimizacija metode ukazuje da su optimalni parametri za analitički pik na potencijalu (Ep ) -0,57 V u odnosu na zasićenu kalomelovu elektrodu (ZKE): pH 6,0, potencijal&nbsp; akumulacije -0,20 V i vreme&nbsp; akumulacije 140 s. U model rastvoru, DOX je određivan u koncentracionom opsegu 4,99-59,64&nbsp; ng mL^-1. Razvijena SW-AdSV metoda je primenjena za određivanje DOX-a u obogaćenom uzorku humanog urina. Niža koncentracija DOX-a 9,89ng mL^-1&nbsp;u voltametrijskoj&nbsp; ćeliji je određivana sa relativnom standardnom devijacijom (RSD) manjom od 6,0%. &Scaron;to se ispitivanih makrolida tiče oni su pokazali redukcione signale u dalekoj negativnoj oblasti potencijala. Ispitivanja direktnom katodnom SWV rađena su u opsegu potencijala od -0,75 V do -2,00 V u odnosu na ZKE, pri čemu su dobijena jedan ili dva redukciona pika u opsegu potencijala od -1,5 V do -1,9 V. Oblik i intenzitet signala zavisi od primenjene pH vrednosti u &scaron;irokoj pH oblasti. Za analitičke svrhe, radi razvoja direktne katodne SWV i adsorptivne inverzne/striping SWV metode, pogodnim su se pokazale neutralna i slabo alkalna sredina tj. pH 7,0 sa&nbsp; E_p na -1,67 V u odnosu na ZKE za ROX i EES i pH 7,2 sa E_p na -1,85 V u odnosu na ZKE za AZI i pH 7,4 sa E_p na -1,64 V u odnosu na ZKE za CLA. Na osnovu snimljenih cikličnih voltamograma na&nbsp; optimalnim pH vrednostima, može se predložiti adsorptivno-kontrolisan kinetički proces na elektrodi u slučaju sva&nbsp; četiri ispitivana jedinjenja. Takođe,&nbsp; ¹H NMR merenja uz potiskivanje&nbsp; signala vode u pH oblasti između pH 6,0 i 10,5 ukazuju na to da su makrolidni molekuli pri optimalnim analitičkim uslovima predominantno u protonovanoj formi preko tercijerne amino grupe &scaron;to potpomaže, u sva&nbsp; četiri slučaja, njihovu adsorpciju na odgovarajuće polarizovanoj Hg(Ag)FE. Optimizovane direktne katodne SWV metode&nbsp; pokazuju dobru linearnost u koncentracionom opsegu 4,81-23,3&nbsp; &micro;g mL^-1 , 4,53-29,8&nbsp; &micro;g mL^-1 , 1,96-28,6&nbsp; &micro;g mL^-1 i 1,48-25,9 &micro;g mL^-1 za AZI, EES, CLA odnosno ROX. Razvijene SW-AdSV metode rezultiraju u linearnom odgovoru pri nižim koncentracionim intervalima 1,0-2,46 &micro;g mL^-1 ,&nbsp; 0,69-2,44&nbsp; &micro;g mL^-1, 0,05-0,99 &micro;g mL^-1 i 0,10-0,99&nbsp; &micro;g mL^-1 , za AZI, EES, CLA i ROX. RSD za sve razvijene metode nije veća od 1,5% izuzev SWV metode u slučaju AZI-a gde je 4,5%. Direktna katodna SWV metoda&nbsp; je uspe&scaron;no primenjena za određivanje EES-a u farmaceutskom proizvodu Eritromicin^&reg; dok SW-AdSV metoda je primenjena u slučaju određivanja EES-a u obogaćenom uzorku humanog urina i&nbsp;za određivanje ROX-a u farmaceutskom proizvodu Runac^&reg; . U svim pomenutim slučajevima, primenjena je metoda standardnog dodatka. Pouzdanost i tačnost elaboriranih procedura u slučaju određivanja EES-a u model sistemu i&nbsp; farmaceutskom proizvodu Eritromicin^&reg; su potvrđena poređenjem sa rezultatima dobijenim primenom HPLC-DAD metode.Nakon preliminarnih studija 3-dehidro-deoksiholne&nbsp; kiseline/3-dehidro-deoksiholata primenom elektrode od staklastog ugljenika (GCE), gde je uočeno da ne dolazi do formiranja redukcionog signala u Briton-Robinson puferu između pH 5,0 i 11,8 primenom direktne katodne SWV, bizmut-film je izdvojen&nbsp; <em>ex situ</em> na povr&scaron;ini iste elektrode od staklastog ugljenika (BiF-GCE) iz uobičajeno kori&scaron;ćenog rastvora za elektrodepoziciju (0,02 mol L^-1 Bi(NO₃)₃, 1,0 mol L^-1 HCl i 0,5 mol L^-1 KBr) i tako pripremljena elektroda je primenjena za karakterizaciju i određivanje pomenutog jedinjenja u alkalnoj sredini. Redukcioni signal ispitivanog analita od analitičkog značaja je uočen jedino primenom BiF-GCE u Briton-Robinson puferusa pH vrednostima između 9,5 i 11,8 u režimu adsorptivne inverzne/stripingvoltametrije sa pravougaonim talasima, dok u slučaju direktnih katodnih SWV eksperimentalnih uslova uočen je slab redukcioni pik sa niskom strujom maksimuma pika. Optimizovani eksperimentalni uslovi za određivanje 3-dehidro-deoksiholata obuhvataju odgovarajuće kondicioniranje elektrode uključujući kondicioniranje&nbsp; <em>ex situ</em> pripremljene BiF-GCE u Briton-Robinson pomoćnom elektrolitu pH 11,8 do stabilizacije struje bazne linije elektrohemijskim cikliranjem potencijala radne elektrode u potencijalskom opsegu između -1,00 i -2,00 V u odnosu na ZKE (blizu 15 puta) i primenu dva ključna parametara adsorptivne voltametrije sa pravougaonim talasima: vreme akumulacije od 30 s i potencijal akumulacije&nbsp; -1,00 V u odnosu na ZKE. Zbog relativne asimetričnosti dobijenih redukcionih signala ispitivanog analita sa&nbsp; E_p na -1,35 V u odnosu na ZKE, &scaron;to je takođe prisutno i u slučaju primene SW-AdSV, određivanje ispitivanog analita je zasnovano na linearnoj zavisnosti između povr&scaron;ine pika redukcionog signala&nbsp; spitivanog analita i njegove odgovarajuće koncentracije i postignuta granica detekcije je 1,43 &micro;g mL^-1 sa dva linearna opsega kalibracione krive od 4,76 &micro;g mL^-1 do 13,0 &micro;g mL^-1 i od 13,0 &micro;g mL^-1 do 23,1 &micro;g mL^-1 za razvoj analitičke metode. RSD metode je 3,22%. Dodatni eksperimenti, elektroliza ispitivanog analita na potencijalu -1,55 V (blizu maksimuma pika ciljnog analita) u odnosu na ZKE su rađeni primenom GCE u obliku ploče (povr&scaron;ina 33,52 cm 2 ) modifikovane sa&nbsp; <em>ex situ&nbsp;</em>pripremljenim bizmut-filmom. Rastvor od interesa uzorkovan je na početku eksperimenta, nakon 2,5 h i nakon 4,5 h tretmana. Ovakvi uzorci su analizirani primenom ¹H NMR merenja uz potiskivanje signala vode u puferskom rastvoru pH 11,8. Može se pretpostaviti da tokom elektrolize 3-dehidro-deoksiholata dolazi do redukcije keto grupe prisutne u strukturi ispitivanog analita.Na osnovu literaturnih podataka da neki od ciljnihmakrolidnih antibiotika kao &scaron;to je npr. azitromicin pokazuju oksidativno pona&scaron;anje na elektrodi od ugljenične paste i elektrodi od zlata deteljna karakterizacija i određivanje&nbsp; četiri makrolidna antibiotika rađena je primenom&nbsp; asične&nbsp;elektrode od ugljenične paste (CPE) koja se sastoji samo od grafitnog praha i parafinskog ulja sa optimizovanih direktnih anodnih SWV metoda. U slučaju EES-a i AZI-a diferencijalna pulsna voltametrija (DPV) je testirana za iste svrhe. Ključni&nbsp; parametar u slučaju razvoja analitičkih voltametrijskih metoda je odabir pH vrednosti pomoćnog elektrolita gde je oblik/simetričnost i intenzitet oskidacionog pika glavni kriterijum prilikom odabira. Kao odgovarajuće pH vrednosti za voltametrijsko određivanje EES-a primenom SWV metode odabrana je pH 8,0 sa E_p na 0,83V u odnosu na ZKE, dok u slučaju DPV metode pH 12,0 sa&nbsp; E_p na 0,55 V u odnosu na ZKE je bila najpogodnija za analitičke svrhe. Za određivanje AZI-a, u slučaju obe SWV i DPV metode pH 7,0 se pokazala najpogodnijom sa E_p analitičkog signala na 0,85 V odnosno 0,80 V u odnosu na ZKE, dok u slučaju CLA i ROX koji su ispitivani samo primenom SWV metode za analitičke svrhe pH 12,0 je bila najpogodnija sredina sa E_p analitičkog signala na 0,65 V odnosno na 0,63 V&nbsp;u odnosu na ZKE. Postignute granice detkcije primenom nemodifikovane CPE i direktne anodne SWV su uglavnom u submikrogramskom koncentracionom opsegu 0,17 &micro;g mL^-1 , 0,32&nbsp; &micro;g mL^-1 i 0,30&nbsp; &micro;g mL^-1, u slučaju EES-a, AZI-a i ROX-a i u niskom mikrogramskom koncentracionom opsegu 1,43&nbsp; &micro;g mL^-1 za CLA. Razvijena SWV metoda sa jednostavnom CPE pokazala se pogodnom za određivanje ROX-a u komercijalnom proizvodu Runac^&reg; tableti. U slučaju optimizovanih DPV metoda postignute granice detekcije za EES i AZI su u niskom mikrogramskom&nbsp; koncentracionom opsegu 1,03&nbsp; &micro;g mL^-1 odnosno 1,53&nbsp; &micro;g&nbsp; mL^-1 . U želji da se&nbsp;postigne niža granica detekcije za AZI, DPV metoda&nbsp; je testirana u kombinaciji sa&nbsp; CPE radnom elektrodom povr&scaron;inski modifikovanom sa zlatnim nanočesticama&nbsp; prečnika 10 nm (Au-CPE) i&nbsp; postignuta granica detekcije je 0,95&nbsp; &micro;g mL^-1 sa&nbsp; E_p analitičkog signala na 0,80 V u odnosu na&nbsp; ZKE. RSD metode u slučaju Au-CPE je 3,5%, dok je u slučaju nemodifikovane CPE 6,0%.&nbsp; Linearnost analitičke metode zasnovane na primeni Au-CPE je dva puta &scaron;ira nego u slučaju&nbsp; primene nemodifikovane CPE.Na osnovu dobijenih rezultata može se zaključiti da&nbsp; odgovarajuće kombinacije&nbsp; optimizovanih voltametrijskih tehnika sa ekolo&scaron;ki prihvatljivim i lako primenljivim radnim&nbsp; elektrodama, kao &scaron;to su Hg(Ag)FE, BiF-GCE i CPE zajedno sa Au-CPE, rezultuju razvojem&nbsp; pouzdanih analitičkih metoda, kako u oksidacionim tako i u redukcionim proučavanjima, koje&nbsp; često omogućuju&nbsp; određivanje tragova analita od farmakolo&scaron;kog značaja u jednostavnim, a u&nbsp;nekim slučajevima i u složenim sistemima.&nbsp;<br>Nowadays in different analytical laboratories there is the increasing number of analytical protocols, either based on highly sophisticated or simpler measurements techniques, which serving for determination of different target analytes of pharmacological importance. Among such target groups of the analyte belongs the antibiotics which present a great discovery in the field of medicine and thanks to them were saved more than seven million people but beside to the mentioned great benefits, antibiotics can cause a large number of side effects and bile acids together with their derivatives which are physiological detergents but if their concentration is notcontrolled they can be cytotoxic to the body. In the present doctoral dissertation the development of analytical methods, primarily analytical voltammetric methods in combination with simple and contemporary electrodes/sensors, for the determination of selected analytes as antracycline antibiotic doxorubicin (DOX), macrolide antibiotics erythromycin ethylsuccinate (EES), azithromycin (AZI), clarithromycin (CLA) and roxithromycin (ROX) and 3-dehydrodeoxycholic acid were performed.Voltammetric characterization and determination of the above mentioned antibiotics using a renewable silver-amalgam film electrode (Hg(Ag)FE) was performed by direct cathodic square-wave voltammetry (SWV) and by highly sensitive adsorptive square-wave voltammetry (SW-AdSV) in aqueous Britton-Robinson buffer solutions as supporting electrolyte covering the wider pH range. The Hg(Ag)FE response of DOX was monitored in the potential range between -0.20 and -0.80 V. For the trace level analysis the method optimization showed that the optimal conditions for the analytical peak with peak potential (E_p) at -0.57 V vs. SCE were: the pH 6.0, the accumulation potential -0.20 V, and the accumulation time 140 s. In the model solutions, DOX was determined in the concentration range of 4.99-59.64 ng mL^-1. The developed SWAdSV method was applied for the determination of DOX in spiked human urine sample. The lowest concentration of DOX of 9.89 ng mL^-1 in voltammetric vessel was determined with the relative standard deviation (RSD) less than 6%. As for the investigated macrolides, they showed reduction signals in fairly negative potential range. During direct cathodic SWV investigations conducted over the potential range from -0.75 V to -2.00 V vs. SCE, either one or two reduction peaks were obtained in the&nbsp; potential range from -1.5 to -1.9 V. For analytical purposes concerning the development of direct cathodic SWV and adsorptive stripping SWV methods the neutral&nbsp; and slightly alkaline media were suitable as pH 7.0 with E_p at -1.67 V vs.&nbsp; SCE for ROX and EES and pH 7.2 and pH 7.4 with E_p at -1.85 V and -1.64 V vs. SCE for AZI and CLA, respectively. Based on the cyclic voltammograms recorded at these pH values, adsorptioncontrolled electrode kinetics process can be proposed for all four investigated compounds. The water suppressed ¹H NMR measurements in the pH range between 6.0 and 10.5 indicated that the macrolide molecules at the optimal analytical conditions are predominantly in protonated form via their tertiary amino groups which supported in all four cases their adsorption on the appropriately polarized Hg(Ag)FE electrode. The optimized direct cathodic SWV methods showed good linearity in concentration ranges 4.81-23.3 &mu;g mL^-1, 4.53-29.8 &mu;g mL^-1, 1.96-28.6&nbsp; &mu;g mL^-1, and 1.48-25.9 &mu;g mL^-1 for AZI, EES, CLA and ROX, respectively. The SW-AdSV methods resulted in the linear responses at lower concentration ranges as 1.0-2.46 &mu;g mL^-1, 0.69- 2.44 &mu;g mL^-1, 0.05-0.99 &mu;g mL^-1 and 0.10-0.99 &mu;g mL^-1, for AZI, EES, CLA and ROX, respectively. The RSD for all developed methods was not higher than 1.5% except the SWV method for AZI with 4.7%. The direct cathodic SWV method was successfully applied for the determination of EES in the pharmaceutical preparation Eritromicin^&reg;, while SW-AdSV was tested in the case of the spiked urine sample and for determination of ROX in pharmaceutical preparation Runac^&reg;. In all above cases, the standard addition method was used. The reliability and accuracy of the above procedures in the case of EES determination in model system and pharmaceutical preparation Eritromicin^&reg; were validated by comparing them with those obtained by means of HPLC-DAD measurements.After initial study of 3-dehydro-deoxycholic acid/3-dehydro-deoxycholate by glassy carbon electrode, where the absence of any reduction peak was observed in the Britton-Robinson buffer solutions between pH 5.0 and 11.8 by direct cathodic SWV, a bismuth-film was electrodeposited ex situ on the same glassy carbon electrode surface (BiF-GCE) from the usually used plating solution (0.02 mol L^-1 Bi(NO₃)₃, 1.0 mol L^-1 HCl and 0.5 mol L^-1 KBr) and such prepared film-electrode was applied for the characterization and determination of the the target analyte in alkaline media. The reduction signal of analytical importance was observed only by BiF-GCE in Britton-Robinson buffer solutions with pH values between 9.5 and 11.8 in adsorptive stripping square-wave voltammetry working regime, while in the case of the direct cathodic SWV experimental protocol only a very poor reduction peak was obtained. The optimized experimental conditions for the 3-dehydro-deoxycholate determination consist of the optimized electrode conditioning including the electrochemical cycling of the <em>ex situ </em>prepared BiF-GCE potentials in the potential span between -1.0 and -2.0 V vs. SCE (nearly 15 times) in the Britton-Robinson supporting electrolyte pH 11.8 till the stabilization of the baseline current, and the application of two key parameters of the adsorptive square-wave voltammetric protocol: the accumulation time as 30 s and accumulation potential as -1.0 V vs. SCE. Because of the relative asymmetry of the obtained reduction signals of the target analyte with peak E_p at -1.35 V vs. SCE, which is still present in the case of the SW-AdSV, the quantification of the target analyte was based on the linear correlation between peak area of the reduction signal and its appropriate concentrations, and reached limit of detection is 1.43 &mu;g mL^-1 and with two linear ranges of calibration curve from 4,76 &mu;g mL^-1 to 13.0 &mu;g mL^-1 and from 13,0 &mu;g mL^-1 to 23,1 &mu;g mL^-1 for the development of analytical method. The RSD of the method&nbsp; was 3.22%. Additional experiments were performed applying GCE with rectangular form (area 35.32 cm²) modified with ex situ prepared bismuth-film for the electrolysis of the target analyte which was performed at the potential -1.55 V (nearly the peak maxima of the target analyte) vs. SCE. The solution of interest was sampled at the beginning of the experiment, after 2.5 h and after 4.5 h of treatment. Such samples were analysed by simply water suppressing ¹H NMR measurements in the buffered solution at pH 11.8. It can be assumed that during electrolysis of 3-dehydrodeoxycholate the reduction of the keto group present in the structure of the target analyte can be occurred.Driven by earlier literature data about the fact that some of the target macrolide antibiotics as e.g. azithromycin showed oxidation behavior at a carbon paste and gold working electrodes detailed characterization and determination of four target macrolide antibiotics were performed on classical carbon paste electrode (CPE) constituted only from graphite powder and paraffin oil with optimized direct anodic SWV methods. In the cases of EES and AZI differential pulse voltammetric (DPV) methods were tested for the same purpose as well. The key parameter in the case of the development of the analytical voltammetric methods is the selection of the pH value of the supporting electrolyte where the shape/simmetry and intensity of the oxidation peak were the criteria. As the appropriate pH value for determination of EES by SWV method the pH 8.0 was selected with E_p at 0.83 V vs. SCE while in the case of the DPV method the pH 12.0 with E_p at 0.55 V vs. SCE was the most suitable for analytical&nbsp; purpose. As for AZI determination, in the case of both SWV and DPV methods the pH 7.0 was the most appropriate supporting electrolyte with the Ep of analytical signal at 0.85 V and 0.80 V vs. SCE, respectively, while in the case of CLA and ROX which were investigated only with SWV method for the analytical purposes the pH 12.0 was the most suitable with E_p at 0.65 V and at 0.63 V vs. SCE. The obtained detection limits applying the bare CPE and the direct anodic SWV are mainly&nbsp; in submicrogram concentration range as 0.17 &mu;g mL^-1; 0.32 &mu;g mL^-1 and 0.30 &mu;g mL^-1 for EES, AZI, and ROX and in the low microgram concentration range as 1.43 &mu;g mL^-1 for the CLA, respectively. The developed method succesfully tested for the determination of ROX in the commercial formulation, Runac^&reg; tablet. In the case of the optimized DPV methods the obtained detection limits for EES and AZI are in the low microgram concentration range 1.03 &mu;g mL^-1 and 1.53 &mu;g mL^-1, respectively. For the improvement of the sensitivity for AZI the DPV method was tested in combination with a&nbsp; CPE working electrode surface modified with gold nanoparticles with diameter of 10 nm (Au-CPE) and reached the limit of detection was 0.95 &mu;g mL^-1 at E_p of 0.80 V vs. SCE. The RSD of the method in the case of the Au-CPE is 3.5% while in the case of the native CPE 6.0%. The linearity of the Au-CPE based analytical method is twice wider then it is case with the bare CPE applying protocol.Based on the obtained results it can be conclude that the appropriate combination of the optimized voltammetric pulse techniques and the environmentally friendly and easy to use working electrodes as Hg(Ag)FE, BiF-GCE and CPE together with Au-CPE resulted in the development of reliable analytical method either in the oxidation or reduction studies, often allowing trace level determination of pharmacological importance target analytes in simpler and in some case complexes systems.

Cette étude comparative porte sur un corpus de récits écrits d’apprenants chinois du français première langue (FL2) et seconde langue étrangères (FL3) en milieu scolaire. Elle a trait à deux groupes d’apprenants de même L1 (le chinois) ayant des accès différents à la langue cible, le français (avec ou sans anglais L2). L’analyse tient compte des différences entre les trois langues, une langue romane (le français), une langue germanique (l’anglais) et une L1 qui ne leur est pas typologiquement apparentée (le chinois). La thèse vise à répondre aux questions suivantes : comment les apprenants chinois en FL2 et FL3 utilisent-ils les temps verbaux du passé à différents niveaux d’apprentissage ? Quels rôles jouent respectivement la L1 et de la L2 dans l’apprentissage de la L3? L’analyse des données s’exerce au niveau sémantique (l’hypothèse de l’aspect, Andersen &amp; Shirai 1994) et fonctionnel (l’hypothèse du discours, Hopper 1979). Les résultats montrent que l’emploi de l’imparfait chez les deux groupes d’apprenants ne suit pas l’hypothèse de l’aspect. Ils montrent aussi que les apprenants ont des difficultés à distinguer trame et arrière-plan du récit. Par ailleurs, on montre quel type d’influence l’acquisition de la L2 exerce sur celle de la L3<br>This comparative study deals with a corpus of written narratives of Chinese FL2 and FL3 learners in school settings. The two groups of learners have the same L1 (Chinese), but different access to the target language, French (with or without English L2). The analysis takes into account the differences between the three languages, a Romance language (French), a Germanic language (English), and a typologically different L1 (Chinese). The thesis deals with the following research questions : how do Chinese FL2 and FL3 learners use past verbal tense at the beginner and intermediate levels. What are the roles of L1 and L2 for FL3 learners ? The data are analysed from a semantic (aspect hypothesis, Andersen &amp; Shirai 1994) and a functional (discourse hypothesis, Hopper 1979) point of view. The results show that the use of the imparfait in both groups of learners does not follow the AH. They also show that learners have difficulties distinguishing the foreground from the background of the narrative. Moreover, both L1 and L2 exert influence over L3 acquisition

Cette thèse porte sur l'apprentissage des temps verbaux du passé composé, de l'imparfait et du plus-que-parfait en français langue étrangère (L2) par des étudiants de première langue (L1) japonaise à l'université au Japon. Dans ce contexte, nous avons expérimenté une approche d'inspiration vygotskienne pour l'enseignement de ces temps, appelée « approche par concepts », où les concepts en jeu (temps physique, aspect, phase du procès) sont présentés initialement pour favoriser un emploi plus conscient, et rendre les apprenants capables d'utiliser les temps selon à la fois leur intention communicative et la norme. On rend compte de deux versions mises en œuvre en 2012 sur 21 semaines et en 2013 sur 12 semaines. Mais l'analyse des résultats nous a conduit à réorienter notre problématique pour prendre en compte le rôle de la L1 dans la conceptualisation. Cela nécessitait de décrire le processus d'énonciation tel qu'il se déroule en temps réel, en L1 et en L2. On a ainsi proposé une nouvelle hypothèse, selon laquelle les concepts médiatisés en L1 sont investis au moment de l'énonciation par l'apprenant pour constituer le niveau conceptuel du verbe au centre de la scène de l'énoncé en L2. En outre, cet investissement correspondrait au développement vers les structures conceptuelles de la L2. Suivant la méthode microgénétique, une trentaine d'extraits issus de verbalisations et de tâches de résolution de problèmes en binômes et individuelles (en pensée à voix haute) sont analysés. Les résultats montrent que pour justifier le choix du temps verbal en L2, les apprenants s'engagent dans une activité métalinguistique spécifique sur des formes de la L1 impliquées dans les renditions verbales. L'interprétation proposée est que c'est un moyen pour eux de focaliser leur attention sur des concepts du japonais jugés adéquats pour constituer le niveau conceptuel du verbe de l'énoncé en français. À la fin de la thèse, des pistes sont proposées pour élaborer une approche par concepts pour les niveaux initiaux dans ce contexte, en tenant compte de cette stratégie d'apprentissage mais aussi en la cadrant<br>This thesis deals with the learning of the compound past (passé composé), imperfect (imparfait) and pluperfect (plus-que-parfait) in French as a foreign language (L2) by Japanese first language (L1) students at a university in Japan. In this context, a vygotskyan approach, known as “concept-based approach”, was experimented with for the teaching of these tenses. The concepts that are involved (time, aspect, tense phase) were initially introduced to promote a more conscious use, and enable learners to employ the tenses according to the intended communicative goal as well as L2 norms. Two implementations with second year students in 2012 and 2013, carried out over 21 weeks and 12 weeks respectively, are reported on. An analysis of the outcomes of these implementations in turn led to a shift in focus of the research problem to also account for the role of the L1 in the process of conceptualization. As a result, this required describing the process of oral enunciation, as it unfolds in real time, in the L1 and L2. A new hypothesis is then proposed that, at the moment of speaking, L1 mediated concepts are used by learners to constitute the conceptual level of the verb at the center of the L2 utterance. Furthermore, we suggest that the use of L1 corresponds to the development towards L2 conceptual structures. About thirty extracts from verbalizations, and peer and individual (think aloud) problem-solving tasks were analyzed, using a microgenetic method. The results show that learners engage in a specific metalinguistic activity on L1 forms involved in verbal construals. An interpretation is then proposed that by doing so, it enables learners to focus on the concepts of the Japanese language they consider adequate to form the conceptual level of the verb predicated in the utterance in French. Finally, suggestions are made to improve a concept-based approach for initial levels in this context, by taking into account this learning strategy and providing a frame for it

This data study concentrates on the past tense marking in the interlanguage (IL) of Chinese speakers of English. Following the assumptions of Hawkins & Lizska, (2003), it is assumed that unlike native speakers of English, Chinese speakers of English have a higher level of optionality within the past tense marking of their grammars. It is claimed that the primary reason for this occurrence is the lack of the functional feature T(ense) [+/-past] in Mandarin Chinese. If a particular functional feature is missing in a learner's L1 grammar, it is thought that it will be absent in one's L2 grammar as well.

This meth&nbsp;od was applied for the determination of the H&nbsp;₂&nbsp;O₂consumption&nbsp; in&nbsp; samples&nbsp; of&nbsp; groundwater&nbsp; fro&nbsp;m&nbsp; the&nbsp; Central&nbsp; Banat&nbsp; region&nbsp; (Province&nbsp; of Vojvodina, Serbia) treated by the Fenton (Fe ²⁺and H ₂O₂ ) and Fenton-&nbsp; like (Fe ³⁺and H ₂O₂ ) reagents to remove natural organic matter (NOM) at&nbsp; differentinitial concentrations of iron species, and of their molar ratios to the initial concentration of H₂O₂ . It was found that the form of Fe (Fe ²⁺ or Fe ³⁺ )and the molar&nbsp; ratio to H ₂O₂influenced the degree of the H₂O₂ decomposition in the groundwater with high NOM content. Besides, in the case of the Fenton-like process, for all initial doses of Fe ³⁺ and H&nbsp;₂&nbsp;O₂, a sign&nbsp;ificant amount of H&nbsp;₂&nbsp;O₂ remained unused, whi&nbsp;ch also indicates a lower efficiency of such system compared to the Fenton process. Screen&nbsp; printed&nbsp; carbon&nbsp; electrode&nbsp; (SPCE)&nbsp; bulk-modified&nbsp; with&nbsp; MnO&nbsp;₂ as&nbsp; a&nbsp; mediator&nbsp; was applied&nbsp; for&nbsp; amperometric&nbsp; determination&nbsp; of&nbsp; the&nbsp; H &nbsp;₂&nbsp;O₂ content&nbsp; during&nbsp; the&nbsp; Fenton&nbsp; (Fe ²⁺ ,&nbsp; H &nbsp;₂&nbsp;O₂)&nbsp; and &nbsp;visible&nbsp; light-assisted&nbsp;,&nbsp; photo-Fenton&nbsp; (Fe ^2+&nbsp; ,&nbsp; H &nbsp;₂&nbsp;O₂ ,&nbsp; h&nu;)&nbsp;&nbsp; based&nbsp; removal&nbsp; of&nbsp; neonicotinoid&nbsp; insecticide acetamiprid (ACT). Under&nbsp; optimized conditions (working potential of 0.40 V vs. SCE, phosphate buffer&nbsp; pH&nbsp; 7.50&nbsp; as&nbsp; supporting&nbsp; electrolyte)&nbsp; amperometric&nbsp; determination&nbsp; of&nbsp; H &nbsp;₂&nbsp;O₂showed&nbsp; a&nbsp; linear dynamic range from 0.01 to 1.24 mmol L -1 (from 0.34 to 42.2 &micro;g mL -1) and the RSD did not exceed 4.2%. In the investigated samples (after appropriate pH adjustment from 2.8 to 7.5 instantly after the sampling&nbsp; to stop or maximum decelerate the oxidation processes, filtering, and storage of the deep- frozen sample with defrosting immediately before the measurements) the H &nbsp;₂&nbsp;O₂&nbsp; contents were determined by the standard addition method by analyzing the corresponding amperometric curves. Parallel HPLC-DAD measurements were performed to monito&nbsp;r the concentration/removal of ACT. In the case of the photo- Fenton process (initial concentrations: 0.31; 2.0 and 3.0 mmol L -1 (70.0; 111.7 and 102.1 &micro;g mL -1 ) of ACT, Fe²⁺ and H &nbsp;₂&nbsp;O₂, respec&nbsp;tively) after 10 min of irradiation H &nbsp;₂&nbsp;O₂ was&nbsp; consumed&nbsp; and&nbsp; it&nbsp; can&nbsp; be&nbsp; consi&nbsp;dered&nbsp; that&nbsp; ACT&nbsp; was&nbsp; removed&nbsp; after&nbsp; 5&nbsp; min.&nbsp; During&nbsp; the&nbsp; Fenton process ACT was removed after 20 min of treatment and around 10% of the initial concentration of the H 2O2 remained still unused.CPE&nbsp; was&nbsp; surface&nbsp; modified&nbsp; with&nbsp; a&nbsp; composite&nbsp; of&nbsp; Pt&nbsp; nanoparticles&nbsp; (&lt;&nbsp; 5&nbsp; nm)&nbsp; on&nbsp; graphitized carbon (Pt-C, 10% Pt on Vulcan XC72) by simply dropcoating method. The unmodified CPE and the&nbsp; modified&nbsp; one&nbsp; (Pt-C/CPE)&nbsp; were&nbsp; characterized&nbsp; by&nbsp;&nbsp; EM/EDS&nbsp; and&nbsp; CV&nbsp; measurements.&nbsp; The&nbsp; PtC/CPE showed remarkable electrocatalytic propertiestoward the electrochemical redox reaction of H&nbsp;₂&nbsp;O₂ compared to&nbsp; modified CPE in phosphate buffer (0.1 mol L -1 ; pH 7.50), as well in acetatebuffer&nbsp; (0.1 mol&nbsp; L -1 ; pH .50) supporting&nbsp; electrolytes. Amperometry of&nbsp; H2O2 in the concentration range from 0.15 to 1.45 &micro;g mL -1 with the Pt-C/CPE showed acceptable linearity, while the obtained values of LOQs were 0.06 &micro;g mL -1&nbsp; (pH 7.50, working potential 0.20 V) and 0.10 &micro;g mL -1 (pH 4&nbsp;.50, working potential 0.50 V). The proposed analytical&nbsp; methods were applied to the determination of the H 2O2 content in commercially available personal care products; i.e., disinfection (pH 7.50) and contact lens cleaning solutions (pH 4.50). The obtained amperometric results are in good agreement with those measured by traditional titanium sulfatereagent based spectrophotometric method with determined concentrations as 2.91% and 2.94%&nbsp; for the disinfection product, and 3.04% and 3.17% for the contact lens solution, respectively. RSD was lower than 2%. The obtained results are in a good agreement with the amounts of the H&nbsp;₂&nbsp;O₂declared by producers (3%) in the both investigated samples. The Pt-C/CPE was also tested for monitoring of the H&nbsp;₂&nbsp;O₂ residual concentration in contact lens&nbsp; solution&nbsp; during&nbsp; its&nbsp; neutralization/decomposition&nbsp; rocess.&nbsp; At&nbsp; 6&nbsp; h&nbsp; of&nbsp;&nbsp; neutralization&nbsp; treatment 24.68 &micro;g mL -1 of the H &nbsp;₂&nbsp;O₂was&nbsp; determined which is almost half of the allowedH2&nbsp;O2 concentration in the case of the contact lens solution concerningthe limit of eye irritation. CPE&nbsp; was&nbsp; surface&nbsp;&nbsp; modified&nbsp; with&nbsp; multiwalled&nbsp; carbon&nbsp; nanotubes&nbsp; (MWCNT)&nbsp; and&nbsp; with composites of MnO₂-MWCNT or Pt-MWCNT by drop coating method to prepare simply, sensitive and reliable volta&nbsp;mmetric sensors for the determination of H &nbsp;₂&nbsp;O₂in selected sample. The results of the&nbsp; SEM/&nbsp;EDS&nbsp; analysis&nbsp; of&nbsp; composite&nbsp; materials&nbsp; have&nbsp; confirmed&nbsp; that&nbsp; the&nbsp; mediators,&nbsp; MnO ₂ and&nbsp; Pt&nbsp; articles, are randomly distributed on the surface of MWCNT and represent nearly 5% (m:m) of the composite expressed as Mn and Pt. CV measurements were performed&nbsp; with prepared electrodes in acetate&nbsp; (pH&nbsp; 4.50),&nbsp; phosphate&nbsp; (pH&nbsp; 7.50)&nbsp; and&nbsp; borate&nbsp; (pH&nbsp; 9.18)&nbsp; buffers&nbsp; to&nbsp; characterize&nbsp; the&nbsp; basic electrochemical&nbsp; behavior&nbsp; of&nbsp; H &nbsp;₂&nbsp;O₂ and&nbsp; to&nbsp; select&nbsp; the&nbsp; working&nbsp; potentials&nbsp; suitable&nbsp; for&nbsp; amperometric determination&nbsp; of&nbsp; this&nbsp; target&nbsp; analyte.&nbsp; The&nbsp; Pt-MWCNT/CPE&nbsp; performs&nbsp; well&nbsp; in&nbsp; phosphate&nbsp; buffer pH .50 and acetate buffer solution pH 4.50 in the&nbsp; negative as well as in the positive polarization range with RSD mainly lower than 2.5%. In case of MnO₂-MWCNT/CPE at &nbsp;0.30 V and above the H&nbsp;₂&nbsp;O₂oxidation signal is rem&nbsp;arkable in slightly alkaline media (pH 7.50), at pH 4.50 this electrode showed poor behavior and at pH 9.18 offered acceptable performance. LOQs were in the &micro;g mL -1 concentration&nbsp; range.&nbsp; H&nbsp;₂&nbsp;O₂was&nbsp; determined&nbsp; in&nbsp; a&nbsp; spiked&nbsp; milk&nbsp; sample&nbsp; by&nbsp; standard addition&nbsp; method after&nbsp; appropriate&nbsp; sample&nbsp; preparation&nbsp; (pH&nbsp; adjustment and&nbsp; centrifugation)&nbsp; and&nbsp; using&nbsp; optimized amperometric p&nbsp;rocedure (acetate buffer pH 4.50, working potential -0.75 V) by Pt-MWCNT/CPE as a working electrode. RSD for three repeated measurements was 2.5%, while the recovery of the method was a bit higher than 71%. The&nbsp; composite&nbsp; materials&nbsp; consisting&nbsp; of&nbsp; MWCNT&nbsp; and&nbsp; Pd&nbsp; (Pd-MWCNT)&nbsp; or&nbsp; Pt&nbsp; containing particles&nbsp; (Pt-WCNT)&nbsp; were&nbsp; applied&nbsp; to&nbsp; the&nbsp; preparation&nbsp; of&nbsp; bulk- modified&nbsp; SPCEs&nbsp; (Pd-MWCNTSPCE and Pt-MWCNT-SPCE) and surface modifiedSPCE (Pd- MWCNT/SPCE). These electrodes, as well as unmodified SPCE and MWCNT-SPCE,&nbsp; were characterized by CV and&nbsp; amperometry&nbsp; in phosphate&nbsp; buffer&nbsp; solution&nbsp; of&nbsp; pH&nbsp; 7.50&nbsp; for&nbsp; the&nbsp; H&nbsp;₂&nbsp;O₂determination.&nbsp; Pd-MWCNT-SPCE&nbsp; and&nbsp; PdMWCNT/SPCEare convenient for the etermination of H 2O2 at working potentials from -0.50 to 0.50 V, and Pt-MWCNT-SPCE at investigated working potentials in the range from -0.80 to 0.70 V. These electrodes were then modified with glucose&nbsp; oxidase (GOx) by drop coating a solution of GOxand Nafion &reg; on their surface, whereby the applied amount of biococktail was optimized. GOx/PdMWCNT-SPCE&nbsp; showed&nbsp; better&nbsp; analytical&nbsp; performance&nbsp; for&nbsp; glucose&nbsp; determination&nbsp; in&nbsp; comparison with&nbsp; GOx/Pd-MWCNT/SPCE.&nbsp; The&nbsp; optimal&nbsp; working&nbsp; potential&nbsp; for&nbsp; GOx/Pd-MWCNT- SPCE&nbsp; was -0.40 V vs. SCE and &nbsp;satisfactory linearity was obtained in the investigated glucose concentration range from 0.16 to 0.97 mmol L -1 (from 29.1 to 174&nbsp; &micro;g mL -1 ), hile the LOQ was 0.14 mmol L -1 (25 &micro;g mL -1 ). The optimized method based on GOx/Pd-MWCNT-SPCE was successfully applied to the determination of glucose in multifloral honey sample.&nbsp; The results are in a good agreement with those&nbsp; obtained by commercially available equipment for determination of glucose. Optimal working potential&nbsp; for&nbsp; GOx/Pt-MWCNT-SPCE&nbsp; was&nbsp; -0.50&nbsp; V&nbsp; vs.&nbsp; SCE,&nbsp; and&nbsp; the&nbsp;&nbsp; satisfactory&nbsp; linearity&nbsp; was obtained in the investigated concentration range ofglucose from 65.8 to 260.6&nbsp; &micro;g mL -1 , with LOQ of 35&nbsp; &micro;g mL -1 . The optimized method based on GOx/Pt- MWCNT-SPCE was successfully applied for determination of glucose in white grape and glucose tablets (Traubenzucker-bonbons) samples, whereby&nbsp; the&nbsp; obtained&nbsp; results&nbsp; were&nbsp; in&nbsp; a&nbsp; good&nbsp; agreement&nbsp; with&nbsp; the&nbsp; results&nbsp; obtained&nbsp; by&nbsp; Accu-Chek device. Based on the results, the developed analytical methods are first of all simple, reliable and suitable&nbsp; for&nbsp; obtaining&nbsp; fast&nbsp; information&nbsp; about&nbsp; the&nbsp; content&nbsp; of&nbsp; H ₂O₂ in&nbsp; different&nbsp; types&nbsp; of&nbsp; samples. Certainly the selection of a suitable working electrode, as well as the optimization of experimental conditions are key factors for the successful determination of H₂O₂.

Purpose: Children with specific language impairment (SLI) lag behind children with typical language (TL) in their grammatical development, despite equivalent early exposure to recasts in conversation (M. E. Fey, T. E. Krulik, D. F. Loeb, & K. Proctor-Williams, 1999) and the ability to learn from recasts in intervention as quickly as do children with TL (K. E. Nelson, S. Camarata, J. Welsh, L. Butovsky, & M. Camarata, 1996). This experiment tested whether this apparent paradox could be attributed to variations in the density of recasts in conversation versus intervention. Method: Thirteen children (7–8 years of age) with SLI and 13 language-similar children (5–6 years of age) with TL were exposed to 3 recast densities of novel irregular past tense verbs (none, conversation-like, intervention-like) over 5 sessions. Outcomes were based on spontaneous conversational productions and a post-test probe. Results: As predicted, at conversation-like densities, children with TL more accurately produced the target verbs they heard in recasts than in nonrecast models (d = 0.58), children with SLI showed no differences, and children with TL produced the verbs more accurately than did children with SLI (d = 0.54). Contrary to expectations, at higher intervention-like recast densities, the SLI group did not improve their accuracy, and the TL group performances were significantly poorer (d = 0.47). Conclusion: At conversational levels, recasts facilitated greater verb learning than models alone but only in the TL group. Increasing recast density to the modest levels in this brief intervention experiment did not benefit children with SLI and led to poorer learning for children with TL. To optimize learning, efficiency of recast distribution as well as rate must be considered.

This dissertation studied the multifunctionality in a sociofunctional perspective of the imperfective past in the Spanish language in the contexts of use of imperfective periphrasis of past and of imperfect of indicative tense. It was also investigated the variation among these forms in the descriptive, habitual, desiderative and narrative functions. The objectives of the research were: a) to map out the encoded functions by the imperfective aspectual forms of past (imperfect of indicative tense and verbal periphrases) in literary short stories written in Spanish; b) to describe the phenomenon of linguistic variation in the functions performed by imperfective aspectual forms of past; c) to examine linguistic and extra-linguistic contexts, prototypical to each function and the factors that constrained the analyzed forms. As theoretical backgrounds, we used principles of Sociofunctionalism by Tavares (2003), as a result of a theoretical connection of the North American approach Linguistic Functionalism (HOPPER; TRAUGOTT, 1993; GIVÃN, 1995), and some assumptions of the Theory of Change and Variation (LABOV, 1972, 1978, 1994 and 2001). The research analyzed data of written language from 24 short stories by Spanish writers, selected based on extra-linguistic parameters (the linguistic zone of Spanish, the narratives and the writers). The results were the following: from 2093 cases, 1803 are in the imperfect past tense of indicative, 86,15% of the total, and 290 in imperfective periphrasis of past in Spanish, which is 13,85% of the total. These data were analyzed according to parameters of transitivity by Hopper and Thompson (1980); types of verbs by Vendler (1957,1967); types of aspectual modifiers; the foreground and background relationship by Hopper e Thompson (1980); narrative unities by Labov (1972); types of discourse; linguistic zones; short stories and selected writers; types of report and voices of the literary narrative. In addition to that, functions were mapped out, and those, which had variation, it was investigated linguistic and extra-linguistic factors, which influenced the use of variants, by subjecting these data to a statistical analysis through the computer program GOLDVARB. Concerning the multifunctionality of imperfective forms of past, it was found, in our research, the following results: descriptive (33,84%), narrative (32,07%), habitual (6%), interactive (1,53%), present (3,07%), future (1,53%), simultaneity (3,07%), courtesy (0,28%), desiderative (8,08%), contrariety (1,53%) and playful (9%). In four of these functions, the analyzed forms vary (according to Labovâs concept, 1978). The imperfect tense is more frequent in the descriptive function (constrained by the presence of two or more arguments in the sentence, discursive level background 2, object not affected by the verbal action, the style of the writers Virgilio PiÃera and Roberto BolaÃo, the absence of volitivity, and dynamic and durative verbs), and in the narrative one (constrained by modality irrealis, discursive level foreground, object not affected by the verbal action, dynamic verbs, sentences whose polarity is negative, and the evaluation of the narrative. Periphrases occur more frequently in the desiderative function (motivated by the absence of agentive subject and of individuated object in the sentence, discursive levels background 1 and 2, and durative verbs), and in the habitual function (motivated by agentive subject, the style of the writers Gabriel GarcÃa MÃrquez and Virgilio PiÃera, dynamic and durative verbs and the presence of the aspectual modifier.<br>Esta tese deteve-se no estudo da multifuncionalidade, numa perspectiva sociofuncionalista, do passado imperfectivo em LÃngua Espanhola, em contextos de uso das perÃfrases imperfectivas de passado e do pretÃrito imperfeito do indicativo. Investigou, ainda, a variaÃÃo entre essas formas nas funÃÃes descritiva, habitual, desiderativa e narrativa. Os objetivos que nortearam a nossa pesquisa foram: a) mapear as funÃÃes codificadas pelas formas aspectuais imperfectivas de passado (pretÃrito imperfeito do indicativo e perÃfrases verbais) em contos literÃrios escritos em Espanhol; b) descrever o fenÃmeno de variaÃÃo linguÃstica nas funÃÃes desempenhadas pelas formas aspectuais imperfectivas de passado e c) examinar contextos linguÃsticos e extralinguÃsticos prototÃpicos a cada funÃÃo e fatores que condicionam as formas sob anÃlise. Deram suporte a nossa pesquisa os pressupostos teÃricos do Sociofuncionalismo, de acordo com Tavares (2003), resultado do casamento teÃrico do Funcionalismo LinguÃstico de vertente norte-americana (HOPPER; TRAUGOTT, 1993; GIVÃN, 1995) e dos postulados da Teoria da VariaÃÃo e MudanÃa (LABOV, 1972, 1978, 1994 e 2001). A pesquisa analisou dados de lÃngua escrita provenientes de 24 contos literÃrios escritos por autores de LÃngua Espanhola, selecionados a partir de parÃmetros extralinguÃsticos (zona linguÃstica do Espanhol, narrativas e autores). Obtivemos um total de 2093 dados, sendo que 1803 desses sÃo de formas do pretÃrito imperfeito do indicativo, 86,15% do total, e 290 de perÃfrases imperfectivas de passado em Espanhol, o que corresponde a 13,85% do total. Esses dados foram analisados conforme os parÃmetros de transitividade, de acordo com Hopper e Thompson (1980); tipos de verbo, conforme Vendler (1957,1967); tipos de modificadores aspectuais; relaÃÃo figura e fundo, conforme Hopper e Thompson (1980); unidades da narrativa, segundo Labov (1972); tipos de discurso; zonas linguÃsticas; contos e autores selecionados; tipos de relato e vozes da narrativa literÃria. Ademais, foi realizado o mapeamento funcional e, nas funÃÃes em que houve variaÃÃo, investigamos fatores linguÃsticos e extralinguÃsticos que condicionaram o uso das variantes, submetendo esses dados a tratamento estatÃstico atravÃs do pacote computacional GOLDVARB. No que tange à multifuncionalidade das formas imperfectivas de passado, encontramos, em nossa pesquisa, os valores descritivo (33,84%), narrativo (32,07%), habitual (6%), iterativo (1,53%), presente (3,07%), futuro (1,53%), simultaneidade (3,07%), cortesia (0,28%), desiderativo (8,08%), contrariedade (1,53%) e lÃdico (9%). Dessas funÃÃes, em quatro, as formas sob anÃlise estÃo em variaÃÃo (de acordo com conceito proposto por Labov, 1978). O imperfeito à mais frequente na funÃÃo descritiva (condicionado por presenÃa de dois ou mais argumentos na oraÃÃo, plano discursivo fundo 2, objeto nÃo afetado pela aÃÃo verbal, estilo dos autores Virgilio PiÃera e Roberto BolaÃo, ausÃncia de volitividade e verbos dinÃmicos e durativos) e na funÃÃo narrativa (condicionado por modalidade irrealis, plano discursivo figura, objeto nÃo afetado pela aÃÃo verbal, verbos dinÃmicos, sentenÃas cuja polaridade à negativa e avaliaÃÃo da narrativa). As perÃfrases ocorrem, mais frequentemente na funÃÃo desiderativa (motivadas por ausÃncia de sujeito agentivo e de objeto individuado na oraÃÃo, plano discursivo fundo [1 e 2] e verbos durativos) e na funÃÃo habitual (motivadas por sujeito agentivo, estilo dos autores Gabriel GarcÃa MÃrquez e Virgilio PiÃera, verbos dinÃmicos e durativos e presenÃa de modificador aspectual).

En esta tesina haremos un aproximamiento a El cuarto de atrás a través de un doble análisis del tiempo. Por una parte, analizamos el dominio y control del tiempo en el relato que demuestra Carmen Martín Gaite, quien lo hace pausar y retroceder a su antojo haciéndonos casi perder el hilo del tiempo. Por otro, haremos un viaje en el tiempo, por esas pausas del relato principal, por medio de distintos objetos para analizar la situación de la mujer de la España de la postguerra.<br>This thesis on El cuarto de atrás (The back room, City Light Publishers) will focus on a double analysis of time. Firstly we will look at Carmen Martín Gaite’s command and control of time in the narrative where by pausing it and travelling back in time she leads the reader to almost lose track of it. Secondly, using different objects we will move through the time lapses in the main narrative to analyse the status of women in post war Spain.

El pretérito indefinido (PIN) y el pretérito imperfecto (PIM) del indicativo del español son dos formas de tiempos aspectuales simples del pasado que han sido frecuentemente objeto de estudio en el terreno de la adquisición del español como L2/LE. La investigación previa establece que existen varios factores que intervienen en distintos niveles lingüísticos y que afectan al uso de PIN y PIM de los aprendices, como son: i) los factores que actúan en el nivel léxico-semántico; ii) en el léxico- sintáctico; iii) en el semántico-discursivo; iv) y en el pragmático-discursivo; así como los factores ligados a v) la transferencia de la primera lengua (L1); vi) al contexto de adquisición (instrucción con inmersión o sin ella) o incluso los vii) ligados al tipo de pruebas usadas para la extracción de datos de estudio. No obstante, entre estos estudios, hay pocos que se centren en aprendices chinos de español. Por ello, todavía carecemos de estudios sistemáticos que analicen su producción lingüística desde la perspectiva de todos o incluso algunos de los factores mencionados en el párrafo anterior. Partiendo de esta situación descrita y con el fin de rellenar este vacío de estudios, el objetivo de esta tesis ha sido recoger datos (que constituyen el corpus Gushi-ELE) y analizar a partir de ellos si los patrones y marcos propuestos por estudios previos para aprendices de español cuyas L1 son indoeuropeas pueden dar cuenta, también, del comportamiento lingüístico de los aprendices chinos. Además, también se analiza si el patrón aspectual de la L1 (chino mandarín) de los aprendices se transfiere a su uso de PIN y PIM en español y si, por esa razón, muestran un patrón de uso característico. Esta tesis se presenta como un compendio de 10 artículos, agrupados en tres bloques relacionados temáticamente. El primer bloque consiste en trabajos que se centran en los datos escritos de 78 aprendices chinos de español del corpus Gushi-ELE. Se analizan los factores que influyen en el uso de PIN y PIM desde cada una de las perspectivas (i) a (v) indicadas en el primer párrafo de este resumen. Siguiendo las líneas abiertas por estudios previos, se analiza qué papel juegan cada uno de esos factores poniendo el foco siempre en el desarrollo del uso de PIN y PIM en la producción escrita de los aprendices chinos. El segundo bloque está compuesto por artículos que también se apoyan en datos escritos de Gushi-ELE pero, a diferencia de los artículos del primer bloque, la perspectiva adoptada es comparativa. Mediante distintos tipos de prueba para la elicitación de los datos, esto es, prueba de huecos (o cloze), de redacción, de opción múltiple y de juicios de aceptabilidad, se llevan a cabo análisis comparativos del uso de PIN y PIM, y se describen los el patrón de desarrollo a lo largo de los niveles de ELE estudiados (B1 a C1 del Marco Común Europeo de Referencia, 2001). También contamos con el análisis entre datos de aprendices de español L2/LE cuya L1 es chino mandarín y de aprendices cuya L1 es inglés para la comparación interlingüística. Así mismo, se presentan y analizan datos de aprendices chinos que aprenden español en el contexto de su L1, chino, en el aula y datos de los que aprenden en contexto de inmersión en la L2 en Barcelona (comparación intralingüística en contextos distintos). Por último, el tercer bloque consiste en un trabajo sobre la relación entre la producción oral y las dificultades de procesamiento. A partir del estudio de las pausas detectadas en la producción de simulaciones orales de anglófonos y de hablantes de español de herencia, se describen y analizan estas en tanto que indicadores de dificultad en el procesamiento (del output). Las pausas (y alargamientos y rellenos) ayudan a localizar qué aspectos de la comunicación (pragmáticos, léxicos, morfosintácticos) resultan problemáticos interlingüísticamente para cada grupo de aprendices, comparados con un grupo de control nativo. Este artículo constituye la etapa inicial de la investigación con datos orales que se abordará, posteriormente, con los datos de los aprendices chinos de Gushi-ELE. La aportación de esta tesis, por tanto, no solo consiste en el estudio de la adquisición de los tiempos aspectuales del pasado en español por aprendices chinos desde distintas perspectivas, sino también en la materialización del propio corpus de producción lingüística de aprendices chinos de español, Gushi-ELE, que pone a disposición de la comunidad investigadora una base de datos relevante para futuros estudios sobre la adquisición del español por este creciente tipo de aprendices de ELE, los sinohablantes.<br>This thesis is presented as a compendium of 10 articles and is grouped into three thematically related blocks. The first block consists of works that focus on written data produced by 78 Chinese learners of Spanish taken from the Gushi-ELE corpus. The factors that influence the use of PIN and PIM are analyzed from each of the perspectives (i) to (v) indicated in the first paragraph of this abstract. The papers in this block analyze the role of each of these factors, concentrating on the development of the use of PIN and PIM in written production by Chinese learners. The second block is composed of articles that are also based on written data from Gushi-ELE. However, unlike the papers in the first block, the perspective adopted in this block is comparative analysis. By means of different types of tests for the elicitation of the data, that is, a cloze test, writing test, multiple choice test and judgments of acceptability test, we carried out comparative analyzes of the use of PIN and PIM and described the development pattern observed from B1 to C1 levels as defined by the Common European Framework of Reference (2001). We also carried out an interlanguage comparison from L2 Spanish learners whose L1 is Mandarin Chinese and learners whose L1 is English. Moreover, we present and analyze data from L1 Chinese learners studying in an at-home context in China in the classroom and data from those who are studying in a context of L2-immersion environment in Barcelona. Finally, the third block consists of study on the relationship between oral production and processing difficulties. In this study of the pauses detected in the non-spontaneous production of L1 English learners and Spanish heritage speakers, pauses are described and analyzed as indicators of difficulty in language processing. Pauses (and lengthenings and fillings) help to locate which aspects of communication (pragmatic, lexical, morpho-syntactic) are inter-linguistically problematic for each group of learners, compared with a native control group. This paper constitutes the initial stage of a research project using oral data that will, at a later date, takle the oral data of Chinese learners in the Gushi-ELE corpus. The contribution of this thesis, therefore, not only consists of the study of the acquisition of past tense aspect in Spanish by Chinese learners from different perspectives, but also of the creation of the Gushi-ELE corpus, which will provide the research community with a useful database for further studies of the acquisition of Spanish by the growing community of L1 Mandarin Chinese learners.

An important strand of research has investigated the question of how children acquire a morphological system using offline data from spontaneous or elicited child language. Most of these studies have found dissociations in how children apply regular and irregular inflection (Marcus et al. 1992, Weyerts & Clahsen 1994, Rothweiler & Clahsen 1993). These studies have considerably deepened our understanding of how linguistic knowledge is acquired and organised in the human mind. Their methodological procedures, however, do not involve measurements of how children process morphologically complex forms in real time. To date, little is known about how children process inflected word forms. The aim of this study is to investigate children’s processing of inflected words in a series of on-line reaction time experiments. We used a cross-modal priming experiment to test for decompositional effects on the central level. We used a speeded production task and a lexical decision task to test for frequency effects on access level in production and recognition. Children’s behaviour was compared to adults’ behaviour towards three participle types (-t participles, e.g. getanzt ‘danced’ vs. -n participles with stem change, e.g. gebrochen ‘broken’ vs.-n participles without stem change, e.g. geschlafen ‘slept’). For the central level, results indicate that -t participles but not -n participles have decomposed representations. For the access level, results indicate that -t participles are represented according to their morphemes and additionally as full forms, at least from the age of nine years onwards (Pinker 1999 and Clahsen et al. 2004). Further evidence suggested that -n participles are represented as full-form entries on access level and that -n participles without stem change may encode morphological structure (cf. Clahsen et al. 2003). Out data also suggests that processing strategies for -t participles are differently applied in recognition and production. These results provide evidence that children (within the age range tested) employ the same mechanisms for processing participles as adults. The child lexicon grows as children form additional full-form representations for -t participles on access level and elaborate their full-form lexical representations of -n participles on central level. These results are consistent with processing as explained in dual-system theories.<br>Ein wichtiger Forschungsbereich hat anhand von offline Daten erforscht wie Kinder das morphologische System erwerben. Die meisten dieser Studien haben berichtet, dass Kinder die regelmäßige und die unregelmäßige Flexion unterschiedlich anwenden (Marcus et al. 1992, Weyerts & Clahsen 1994, Rothweiler & Clahsen 1993). Diese Studien haben dazu beigetragen den Erwerb und Organisation von linguistischem Wissen besser zu verstehen. Die offline Methoden messen morphologische Verarbeitung allerdings nicht in Echtzeit. Bis heute ist wenig darüber bekannt wie Kinder flektierte Wortformen in Echtzeit verarbeiten. Die vorliegende Arbeit hat diese Frage in 6- bis 11jährigen monolingualen Kindern (in zwei Altersgruppen) und in einer Erwachsenen-Kontrollgruppe anhand von -t Partizipien (z.B. gemacht), -n Partizipien ohne Stammveränderung (z.B. geschlafen) und -n Partizipien mit Stammveränderung (z.B. gebrochen) untersucht. Dekomposition von Partizipien und deren ganzheitliche Speicherung in assoziativen Netzwerken wurden auf zwei Repräsentationsebenen (zentrale Ebene, Zugriffebene) und, auf der Zugriffsebene, in zwei Modalitäten (Produktion, Verstehen) experimentell getestet. Ein cross-modal priming experiment untersuchte die zentrale Repräsentation von Partizipien. Volle morphologische Primingeffekte sprechen für eine dekomponierte Repräsentation, partielle Primingeffekte für ganzheitliche aber verbundene Repräsentationen. In einem speeded production experiment wurde die auditive Zugriffsrepräsentation und in einem lexical decision experiment die visuelle Zugriffsrepräsentation von Partizipien untersucht. (Ganzwort-) Frequenzeffekte wurden als Beleg für Ganzwortrepräsentationen gewertet. Bezüglich der zentralen Ebene zeigen die Ergebnisse, dass -t Partizipien aber nicht -n Partizipien dekomponiert repräsentiert sind. Bezüglich der Zugriffsebene zeigen die Ergebnisse, dass -t Partizipien entsprechend ihrer Morpheme repräsentiert sind und zusätzlich Ganzwortrepräsentationen haben können, zumindest im Altersbereich von Neun- bis Elfjährigen (Pinker 1999 and Clahsen et al. 2004). Weitere Ergebnisse zeigten, dass -n Partizipien auf der Zugriffsebene Ganzwortrepräsentationen haben, und dass -n Partizipien ohne Stammveränderung die morphologische Struktur enkodieren können (cf. Clahsen et al. 2003). Die Daten weisen auch darauf hin, dass die Verarbeitungsstrategien für -t Partizipien, zumindest in Neun- bis Elfjährigen, unterschiedlich angewandt werden. Die Ergebnisse werden als Evidenz dafür interpretiert, dass Kinder (in dem getesteten Altersbereich) dieselben Verarbeitungsmechanismen für Partizipien nutzen wie Erwachsene. Das kindliche Lexikon wächst, wenn Kinder zusätzliche Ganzwortrepräsentationen für -t Partizipien auf der Zugriffsebene bilden und ihre Ganzwortrepräsentationen für -n Partizipien auf der zentralen Ebene ausdifferenzieren. Diese Ergebnisse sind konsistent mit den Annahmen dualer Verarbeitungstheorien.

In the last five years, the world has experienced unexpected tragic events and natural disasters. However, international tourism is expected to grow continually and tourists are therefore becoming more concerned with safety and security during their international travel. This dissertation investigated individualsâ risk perception of vacationing at two scenario international destinations, Australia and Japan. While ten dimensions of perceived risk in international leisure travel were identified in the literature and one additional dimension of â Communication Riskâ was proposed for this study, only seven dimensions were found in this study: â Health Risk,â â Value Risk,â â Psychological Risk,â â Social Risk,â â Terrorism Risk,â â Equipment Risk,â and â Communication Risk.â The other four dimensions â â Financial Risk,â â Time Risk,â â Satisfaction Risk,â and â Political Instability Riskâ â were either merged into other dimensions or did not appear as an independent dimension in this study. The â Communication Riskâ which was proposed in this study was found to be a valid dimension of perceived risk in vacationing at international destinations. The relationships of perceived risk to other factors were also examined. Individualsâ characteristics of novelty seeking were negatively related to their risk perception, as were individualsâ proficiency of the destinationâ s native language. Those who have experience visiting the destination tended to perceive less risk in vacationing at the destination; the more familiarity/expertise with the destination, the less risk was perceived. When an individual perceived a higher level of risk towards a destination, s/he was less likely to vacation at the destination. Individuals were more likely to choose a packaged tour than independent travel when they had a higher level of risk perception towards vacationing at a particular international destination.<br>Ph.

Most Brazilian students learning English face difficulty when studying thepresent perfect. It is one of the most challenging aspects of the Englishlanguage for Portuguese speakers due to the similar form with a divergentsemantic value. The Brazilian Portuguese present perfect forces iteration andthe student automatically transfers the same meaning when translating anEnglish sentence literally. Brazilian learners get confused about when and inwhat situations to use the English present perfect and frequently are not able todistinguish it from the simple past use. This study is comprised of two parts.First, a comparative study was done to investigate which Portuguese tensetranslators of famous literary books consider to be equivalent to the Englishpresent perfect according to the message which is being conveyed. Thedatabase used was the bidirectional parallel corpus of English and PortugueseCOMPARA. Second, textbooks developed to teach English in Brazil wereanalyzed in order to verify from what perspective students were beinginstructed concerning the present perfect and whether the semantic differencesbetween the two languages were pointed out. According to the translationcorpus, the English present perfect is mostly equivalent to Brazilian Portuguesesimple past. Adverbs are also often needed to express the English presentperfect meaning in Portuguese. The textbooks were found to present poorexplanations and seem not to call the learners’ attention to the source of the problems. Textbooks do not stress the importance of the semantic value and thecontext, and do not call attention to the different meanings between theBrazilian and the English present perfect.

O presente trabalho pretende dissertar sobre a construção narrativa dos conceitos de estrutura e sujeito no livro A miséria da teoria do historiador inglês Edward Palmer Thompson (1924 – 1993). Com a crise do marxismo em 1956 intelectuais de esquerda começam a repensar o marxismo como teoria e como prática política. Nas décadas de 1960 e 1970 o filosofo francês Louis Althusser (1918 – 1990) adquire um grande prestigio na historiografia marxista inglesa através dos integrantes da segunda new left. O livro aqui analisado é uma resposta à infiltração do marxismo althusseriano na Inglaterra. Os conceitos de estrutura e sujeito são avaliados a partir de três pontos constitutivos. Primeiro, o mercado linguístico da época de Thompson; segundo, a gramática do livro o que possibilita compreender as regras semânticas e pragmáticas do texto; por último, uma análise dos nomes próprios e conceitos que compõe o texto, a partir da problemática dos usos do passado contido nas palavras. Desta forma pode-se compreender que a constituição narrativa dos conceitos configura-se como uma forma de um reenquadramento do passado na escritura historiadora para recompor a temporalidade fissurada com a crise marxista de 1956.<br>This work intends to elaborate on the narrative construction of the concepts of structure and subject in the book The Poverty of Theory of the English historian Edward Palmer Thompson (1924-1993). With the crisis of Marxism in 1956, left-wing intellectuals started to rethink Marxism as theory and as political practice. In the 1960s and 1970s the French philosopher Louis Althusser (1918-1990) acquired a great prestige in the English Marxist historiography through the members of the second new left. The book here analyzed is a response to the infiltration of Althusserian Marxism in England. The concepts of structure and subject are evaluated from three points of incorporation. First, the language market of the Thompson times; second, the book grammar which enables to understand the semantic and pragmatic rules of the text, and finally, an analysis of proper names and concepts that compose the text, from the problematic uses of past contained in words. Thus one can understand that the narrative constitution of concepts appears as a way of reframing the past in the historian writing to reconstruct the temporality cracked with Marxian crisis of 1956.

About fifty out of approximately 250 irregular English verbs have regular alternatives in the past tense and/or the past participle. There are often marked preferences for using the irregular or the regular form of the verbs, influenced by several factors. The present corpus-based study investigates the distributions in contemporary British (BrE) and American English (AmE) of the two alternative past tense forms for the two verbs “light”, and “speed” as well as the two past participle variants for the verb “prove”. The factors which are considered in the study are (1) language variety, (2) past tense vs. past participle, and (3) transitive vs. intransitive use of the verbs. It is demonstrated that there are (verb specific) significant differences in frequencies across the factors. Some issues for the study are discussed, in particular unreliable tagging in the corpora used as well as potential sources for random or systematic errors. Some avenues for additional research are proposed.

En esta tesina mostramos algunos de los recursos narrativos que utiliza el autor Juan Marsé para trasmitir una noción de cómo era la vida en España de los años 40. Nos deja conocer la lectura de los protagonistas, cuáles son las películas los atraen, los nombres de las estrellas de fútbol del día, etc. Marsé describe detalles de la vida barcelonesa mencionando, por ejemplo, las calles, los bares, los cines, las paradas de tranvía. Utiliza además unas medidas paratextuales para trasmitir al lector un sentimiento adecuado del lugar y del tiempo, Barcelona en 1945. Nos permitimos reflexionar a partir de la hipótesis de que esta novela histórica del pasado reciente pudiera ayudar a cicatrizar las heridas inflingidas por el franquismo en la sociedad española. Un rasgo destacado de la novela  es la ausencia del padre. El resultado de la Guerra Civil privó a muchos jóvenes de modelos de rol masculinos diferentes de los falangistas. Los hombres que restaron fueron los policías, representantes de la opresión. Era un tiempo sin esperanza. Además, la novela ofrece varios puntos de vista sobre el carácter de la memoria. La pregunta que se plantea es ¿podemos confiar en nuestra memoria? La respuesta que, según nuestra interpretación, sugiere el autor es que debemos considerar con dudas lo que imaginamos recordar. Y que la frontera entre mentira y realidad es, por lo menos, borrosa.

Notre thèse a pour objet les temps du passé de l’indicatif en français (en particulier le passé simple, l’imparfait et le passé composé). Les approches sur le temps sont multiples et elles utilisent des concepts variés qui tentent d’expliquer le fonctionnement de ces formes à travers de nombreux paradigmes. Ainsi, la grammaire scolaire se contente de stipuler que les temps du passé de l’indicatif ont pour rôle de situer les événements dans l’époque passée. Mais, si l’on confronte les théories traditionnelles avec les approches linguistiques plus récentes sur la sémantique des temps verbaux, on observe que l’emploi de ces temps implique à la fois une référence temporelle, une visée illocutoire et discursive ainsi qu’une attitude psychologique et pragmatique. Nous étudions donc dans ce travail les usages en discours des temps du passé à partir de leurs valeurs en langue en essayant de montrer de quelle manière les contenus temporel, aspectuel et modal interfèrent et se complètent dans l’expression verbale du passé. Nous mettons en évidence le fait que le choix des temps du passé est motivé également par la manière de se représenter les événements et par le type d’information que veut faire passer le locuteur à son interlocuteur. L’emploi des temps du passé caractérise également des types particuliers de discours et participe à la cohérence informationnelle du texte. Enfin, le traitement d’approches aspectuo-temporelles, textuelles et pragmatiques nous conduira à adopter le modèle essentiellement praxématique pour une étude du fonctionnement des temps du passé en langue et en discours dans un texte littéraire, Thérèse Desqueyroux de François Mauriac<br>Our work has for object the times of the past in French (in particular the simple past, the imperfect and the present perfect). The approaches at the time are multiple and they use varied concepts which try to explain the functioning of these forms through of many paradigms. So, the grammar contents with stipulating that the times of the past have for role to place the events in the past time. But, if we confront the traditional theories with the more recent linguistic approaches on semantics of the tenses of the verb, we observe that the use of these times implies at the same time a temporal reference, an aim illocutoire and discursive as well as a psychological and pragmatic attitude. We study in this work the uses in speech of the past time from their values in language by trying to show, first of all, how temporal, aspectual and modal contents interfere and complement each other in the verbal expression of past. We highlight the fact that the choice of the past times is motivated by the way of representing itself the events and by the type of information that the speaker wants to introduce to his interlocutor. The employment of the past times also characterizes particular types of speech and participates in the informative coherence of the text. The treatment of aspectuo-temporal, textual and pragmatic approcaches leads us to adopt the model primarily praxematic for a study of the use of the past times in language and speech in a literary text, Thérèse Desqueyroux of François Mauriac

The purpose of this essay is to investigate the translation stategies chosen by the translator when translating present and past participles in contracted sentences in a French scientific article into Swedish. Previous research shows that the French language has a predilection for an elliptical sentences structure, whereas the Swedish language prefers complete clauses. This difference could eventually cause problems during the translation process when translating the French present and past participles in contracted sentences into Swedish. The source text has been translated into Swedish. The translation of the participles has then been categorized according to the strategy chosen by the translator and then analyzed according to the theoretical models by Eriksson (1997, 2015) and Ingo (2007). Our study shows that the majority of the present and past participles in contracted sentences in the source text has been translated into complete causes in the target text. The relative clause seems to be the most common choice by the translator. However, other strategies have sometimes been chosen, often as a consequence of an already complicated sentence structure in the target text or due to stylistic choices.

Nous traitons ici de l’enseignement en Irak sous l'Empire Ottoman, aux XIXe et XXe siècles, dans un pays autrefois multi-ethnique et pluri-confessionnel. Pendant les Tanzimat, l'Irak bénéficia des réformes du gouverneur Midhat Pacha. Plusieurs écoles Chrétiennes, Juives et des différentes communautés existaient avant les missions religieuses occidentales (Carmes, Dominicains. Alliance Israélite Universelle). L'évolution des différents établissements et leurs liens éventuels sont décrits ici. À partir d'archives françaises et iraquiennes, un panorama précis de l'enseignement irakien s'établit après 1908. Nous mettons en évidence le rôle des écoles privées des missions françaises catholiques et juives qui ont diffusé la langue et la culture (laïcité) françaises en Irak (imprimerie, traductions, presse), avec l'appui de la diplomatie française au-delà du gouvernement de Vichy. Sept portraits d'intellectuels irakiens illustrent l'influence française en même temps que la réhabilitation de la langue arabe. Nous pensons contribuer ainsi à une meilleure connaissance de l'Irak au XIXe siècle et revivifier les échanges culturels entre notre pays et la France<br>We are dealing here with education in Iraq under the Ottoman Empire, in the nineteenth and twentieth century's, in a once multi-ethnic and multi-confessional country. During the Tanzimat, Iraq benefited from the reforms of Governor Midhat Pasha. Several Christian, Jewish and different communities' schools existed before Western religious missions (Carmelites, Dominicans, Alliance Israelite Universally). The evolution of the different institutions and their possible links are described here. From French and Iraqi archives, a precise panorama of Iraqi education is established since 1908. We highlight the role of the private schools of the French Catholic and Jewish missions which disseminated French language and culture (secularism) in Iraq (printing, translations, press), with the support of French diplomacy till and after the government of Vichy.Seven portraits of Iraqi intellectuals illustrate the French influence as well as the rehabilitation of the Arabic language. We believe we contribute in this way to a better knowledge of Iraq in the nineteenth century and to revitalize the cultural exchanges between our country and France

L’intégration du contexte dans l’analyse de la subordonnée participiale au participe passé permet d’établir plusieurs catégories de cette construction, selon qu’elle est employée seule, qu’elle contient un marqueur temporel ou l’auxiliaire étant. Lorsqu’elle n’a pas ces éléments, la construction est toujours en relation de coréférence événementielle avec son contexte d’apparition. Elle est toujours composée de verbe résultatif, borné à gauche et à droite, et est séparée de la proposition qui l’héberge par un intervalle. Deux types de constructions participiales se dégagent de cette catégorie. La première n’apporte aucune information nouvelle dans le discours. Elle indique une Généralisation du contexte antérieur et est en relation de Consécutivité avec la proposition qui l’héberge. Elle peut être un connecteur ou un introducteur de cadre temporel. La seconde est rhématique par l’aspect de son procès. C’est une Particularisation du contexte antérieur qui est souvent en relation de Narration avec la PH. La construction qui contient un marqueur temporel se rapproche de celle qui n’en a pas dans plusieurs aspects. Mais elle diffère de celle-ci parce que le marqueur peut servir à conférer au participe le caractère résultatif s’il n’en a pas, ou une autonomie syntaxique. En ce qui concerne celle qui est composée de l’auxiliaire étant, elle se distingue des deux autres dans plusieurs angles. D’abord, si elle est contextuelle, son procès est souvent distinct de celui de son contexte d’apparition. Ensuite, théoriquement, elle peut contenir n’importe quel participe passé, avec un procès borné seulement à droite, mais pas à gauche. Enfin, elle entretient avec ce contexte et avec la proposition qui l’héberge plusieurs types de relations de discours qu’on ne peut avoir avec les autres types de subordonnées participiales<br>The typology of French subordinate participial clauses studied here is grounded in their context, which is shown to partially determine their distribution (‘pure’ or naked, introduced by a temporal adverbial, or yet containing the auxiliary étant ‘being’). When naked, the clause always entertains a relationship of coreference with the events denoted in the preceding context, and its verb is resultative, yielding a temporal interval between the two eventualities. In some cases, the participial clause does not introduce any new information : it simply generalises the contents of the (not necessarily immediately) preceding sentence, indicates that the main clause is consequent upon it, and functions like a discursive connective or a pure temporal adjunct. In other cases, it is rhematic, at least in so far has it provides aspectual specifications, and thus play anundeniable narrative rôle. When a temporal expression (une fois, sitôt…) introduces the clause, the semantic value of the participle is also specified, and the clause acquires a form of syntactic autonomy it does not have otherwise. Finally, when the auxiliary étant occurs, the subordinate clause can denote a hitherto unknown eventuality, whose aspectual properties are distinct from the aforementioned cases ; in particular, reference is only made to the end point, never to the beginning of the action thus described. This third type of participial clause is also shown to entertain textual and/or discursive relations with the context that are crucially different from the other types

Este estudio investiga la enseñanza del pretérito perfecto compuesto en el aula de españolcomo lengua extranjera a nivel escolar en Suecia. El objetivo de esta monografía es ver sipuede ser beneficioso enseñar el pretérito perfecto compuesto mediante canciones en español,que incluyen el pretérito perfecto compuesto en sus versos, como recurso didáctico. Losparticipantes son treinta y cuatro alumnos, divididos en dos grupos, de ELE en el octavo yocho profesores de español. Este estudio se realiza mediante observaciones en clase, dospruebas para los alumnos y una encuesta entre los profesores.Los resultados del estudio muestran que los profesores que participan en el estudio consideranque la mayoría de sus alumnos tienen problemas para aprender el pretérito perfectocompuesto. Los resultados de las pruebas indican que los alumnos que hacen parte del primergrupo de estudio, que tuvieron una enseñanza inductiva con canciones en español,aumentaron su destreza para utilizar el pretérito perfecto compuesto tanto con los verbosregulares como con los irregulares. Los alumnos que hicieron parte del segundo grupo,quienes recibieron una enseñanza deductiva, aumentaron su destreza en usar/aplicar elpretérito perfecto compuesto menos que el primer grupo cuando trata de los verbosirregulares. Sin embargo, estos alumnos aprendieron utilizar el pretérito perfecto compuestocon los verbos regulares mejor que los del primer grupo.Además, nos indigamos si se presentaba una posible diferencia en relación con el interés y lamotivación para aprender entre chicos y chicas dado el tema romántico de las canciones. Losresultados muestran una ligera mayoría en los resultados de las alumnas.<br>This study investigates the teaching of the past perfect tense in the Swedish classroom ofSpanish as a foreign language. The purpose of this essay is to see if it is profitable to teach thepast perfect tense with songs in Spanish, which include the past perfect tense in the lyrics, asan educational resource. The participants are thirtyfour students, divided into two groups, inthe eight grade who study Spanish as a foreign language, and eight Spanish teachers. Thestudy was made through observations in class, two tests by the students and a survey with theteachers.The results of the study show that the teachers who participated in the study consider that themajority of their students have problems learning the past perfect tense. Furthermore, theresults show that the students who were part of the first group, who received an inductiveeducation including Spanish music, increased their abilities of using the past perfect tenseboth with regular and irregular verbs. The students who were part of the second group andwho learnt/were taught by means of the deductive approach increased their abilities to use thepast perfect tense less than the first group when it came to the irregular verbs. However, theylearnt to use the past perfect tense with regular verbs better than the first group.Furthermore, we also investigated if there were any differences according to the interest andthe motivation to learn between the boys and the girls. The results were slightly higher amongthe girls.

De nombreuses études ont observé l’importance et l’effet de la langue maternelle dans les cours d’une langue étrangère mais celle-ci n’a pas été pleinement valorisée dans l’enseignement. Dans un cadre didactique expérimental, nous avons examiné chez des arabophones apprenants du FLE l’utilisation de la médiation par la langue arabe. Cette étude explore l’acquisition de l’imparfait sur le plan fonctionnel, qui constitue toujours un enjeu pour l’enseignement/apprentissage. Cette étude s’est penchée notamment sur l’assimilation des relations de simultanéité entre procès que l’imparfait permet de construire en contexte : la simultanéité totale, la simultanéité partielle et l’interruption. À travers un dispositif de constructions des connaissances associé à une approche médiative (et sans médiation pour le groupe contrôle) ainsi que des instruments de mesure initiaux et finaux, nous observons que la référence à la L1 arabe peut freiner l’appropriation de l’imparfait en induisant de la confusion et en provoquant un suremploi de l’IMP avec la simultanéité partielle et l’interruption. La principale difficulté réside dans les contextes perfectifs typiques du passé composé avec les verbes d’achèvement ainsi que dans les contextes imperfectifs atypiques de l’imparfait avec les verbes d’accomplissement. Le groupe expérimental a notablement moins bien réussi dans ces deux configurations, surtout lorsqu’elles se trouvaient dans un seul et même énoncé. Nous concluons ainsi que le transfert positif n’a été que très partiellement efficace, probablement du fait qu’il n’a pas pu être automatisé chez le groupe expérimental<br>Many studies have observed the importance and the effect of the mother tongue in foreign language classes, but it has not been fully valued in teaching. In an experimental didactic framework, we examined the use of mediation through the Arabic language among Arabic-speaking learners of French as a foreign language. This study focuses on the acquisition of the imperfect on the functional level, which is always a challenge for teaching/learning. This study focused in particular on the assimilation of the relations of simultaneity between processes that the imperfect may build in context: total simultaneity, partial simultaneity and interruption. Through a knowledge construction device associated with a mediative approach (and without mediation for the control group) as well as initial and final measurement instruments, we observe that the reference to the Arabic L1 can slow down the appropriation of the imperfect, by inducing confusion and causing overuse of the IMP with partial simultaneity and interruption. The main difficulty lies in typical perfective contexts of the passé composé with achievement verbs as well as in atypical imperfective contexts of the imperfect with accomplishment verbs. The experimental group performed notably less well in these two configurations, especially when they were found in a single utterance. We thus conclude that the positive transfer was only very partially effective, probably because it could not be automated in the experimental group

Este trabalho tem como objetivos facilitar a leitura da obra de Sóror Maria do Céu e contribuir para a divulgação desta escritora barroca, que possui uma vasta produção literária no século XVIII mas que permance grandemente desconhecida nos círculos literários e académicos do presente século. A introdução explora o aspecto da viagem alegórica da alma, representada por personagens de uma narrativa e tendo como protagonista uma personagem feminina -- a Peregrina. Esta embarca numa viagem à procura de uma vida eterna feliz e recompensadora, No entanto durante a sua viagem, depara-se com um conjunto de desafios que precisa ultrapassar para atingir a vida eterna. Apresentamos alguns dados históricos e socioculturais de Portugal no século XVII e XVIII e oferecemos uma pequena biografia da autora, Maria do Céu. Também está incluída uma explicação sucinta sobre o estilo artístico de escolha, ou seja, os elementos literários que constituem esta novela alegórica, assim como um resumo dos catorze capítulos de Enganos do bosque, desenganos do Rio. Durante a análise da obra de Maria do Céu, revelamos as caraterísticas principais dos personagens e consideramos Enganos do bosque, desenganos do Rio juntamente com outras duas obras: Pilgrim's Progress, do escritor inglês John Bunyan e História do Predestinado Peregrino e seu irmão Precito, do escritor português Alexandre de Gusmão. Deste modo expomos as semelhanças e diferenças entre as viagens peregrinas dos protagonistas destas obras e realçamos os objetivos originais da escritora feminina e que são distintos dos autores masculinos: através da personagem Peregrina, Maria do Céu narra o aperfeiçoamento da alma até ao ponto de união mística com o pastor do bosque, ou seja, união da alma com o seu criador, Jesus Cristo. Por fim, antes da edição da novela alegórica de Maria do Céu, oferecemos uma lista de alterações gramaticais efetuadas nesta edição, e que têm como objetivo ajudar o leitor moderno na compreensão desta obra.

Cette thèse propose une analyse du conditionnel en français basée sur des concepts énonciatifs et aspecto-temporels, dont le plus important pour ce temps grammatical se révèle être celui de « référentiel temporel ». Après avoir exposé le cadre théorique de J.-P. Desclés et Z. Guentchéva utilisé pour ce travail, nous présentons tout d’abord une application de ce modèle à des temps verbaux de l’indicatif (présent, imparfait et futur), puis nous abordons les problématiques du discours rapporté et des énoncés en si, que concernent à la fois les temps de l’indicatif mentionnés et le conditionnel. Nous passons ensuite à l’analyse du conditionnel lui-même, qui est sous-tendu par un invariant sémantique : ce temps grammatical pose la relation prédicative aspectualisée (le procès) dans un référentiel autre que le Référentiel Énonciatif, l’actualisation de ce procès vers le Référentiel Énonciatif se faisant alors de différentes manières selon les trois classes d’emplois du conditionnel que nous avons dégagées (« futur dans le passé », hypothèse, et désengagement). Chaque classe est étudiée en détail et divisée en sous-classes. Nous proposons dans une troisième partie une étude des équivalents en allemand du conditionnel. Cette langue utilise diverses formes verbales, relevant des modes Indikativ, Konjunktiv I et II, ainsi que de la forme en würde + infinitif, pour exprimer les valeurs du conditionnel. Pour finir, une comparaison entre cette dernière forme et le conditionnel met en évidence la pertinence du concept de référentiel temporel puisqu’il permet d’expliciter le rapprochement sémantique entre deux formes verbales morphologiquement différentes<br>This thesis proposes an analysis of the French conditional based on enunciative and aspecto-temporal concepts, where the most important concept for this grammatical tense is shown to be that of “temporal reference framework”. Having expounded the theoretical framework of J.-P. Desclés and Z. Guentchéva, we will first present an application of this model to verb tenses in the indicative (present, imperfect and future), after which we will take up the problematics of reported speech and si utterances which both the indicative tenses mentioned and the conditional are concerned with. We will then move on to the analysis of the conditional itself which is underlain by a semantic invariant: this grammatical tense places the aspectualized predicative relation (the process) in a reference framework other than the Enunciative Reference Framework. The actualization of this process in another reference framework different from the Enunciative Reference Framework is realized in different ways according to the three classes of usage of the conditional which we have singled out (“future in the past”, hypothetical value, disengagement). Each class is studied in detail and divided into sub-classes. In a third part we study the equivalents of the conditional in German. This language makes use of some verb forms of Indikativ and Konjunktiv I and II moods as well as the form würde + infinitive, to express the values of the conditional. Finally, a comparison of this last form with the conditional will reveal the pertinence of the concept of temporal reference framework since it explains the semantic connection between two morphologically different verb forms

The present study deals with the use of participle constructions, adverbs as well as the formal style of a French text about winemaking. The study aims to discuss my translation choices as well as studying participle constructions and adverbs while taking the cultural context in consideration. The results show that the use of present participle, gerund and past participle without auxiliary verbs as well as the use of adverbs in the beginning of a sentence, have a formal effect of the French text. However, the use of past participles with auxiliary verbs do not have such an effect. The cultural context is shown in the formal style due to grammatical choices and is also shown in the variety of the French wine vocabulary, much richer than the Swedish. To be adequate for the Swedish reader, the target text had to be less formal, to correspond to the Swedish tradition of writing clearly.

Au VIème siècle après J.-Ch., les structures de la langue latine ne correspondent plus tout à fait aux normes de la langue classique, aussi bien du point de vue morphologique et sémantique que syntaxique. A travers l’étude comparative des constructions absolues entre un corpus d’auteurs classiques et un corpus d’auteurs tardifs, nous montrons l’émergence de nouvelles valeurs du participe, particulièrement le participe passé actif de verbes non déponents, en latin tardif, ou plus exactement une fréquence accrue de valeurs parfois attestées en latin classique et archaïque<br>In the 6th century A.D., the structures of the Latin language no longer entirelycorrespond to the norms of Classical Latin, from a morphological and semantic perspective aswell as a syntactical one.By means of a comparative study of absolute constructions in a corpus of classicalauthors and a corpus of later authors, we show the emergence of new participle values, inparticular the active passive participle of non-deponent verbs in Late Latin, or more precisely,a greater frequency of values sometimes attested in Classical and Archaic Latin

L’étude présente l’histoire de la classe du participe à travers un corpus de grammaires del’espagnol, du français, de l’italien et du portugais parues entre le XVe et le XVIIIe siècle.La démarche comparative s’appuie sur le principe méthodologique de la mise en série d’une centaine d’ouvrages regroupés et confrontés selon des paramètres variables : la chronologie, le thème ou la tradition grammaticale de la langue-objet.La première partie aborde la question de la catégorisation en linguistique et s’interroge sur la nature des formes non finies du verbe, tout particulièrement du participe et de son emploi dans les formes verbales analytiques. La deuxième partie traite de l’histoire du participe sous un angle général. Ainsi, après avoir donné un aperçu des aspects problématiques qui intéressent les grammairiens grecs et latins, l’analyse se centre sur le traitement de la classe dans les grammaires des langues romanes. La troisième partie s’attache à étudier les approches et les concepts dont se servent les grammairiens de la Renaissance pour traiter les temps composés ainsi que la façon dont ils décrivent et (re)catégorisent les formes participiales de ces temps verbaux<br>The study investigates the history of the word-class of participle through a close study of a corpus of French, Spanish, Portuguese and Italian grammars which were published between the 15th and 18th centuries. The comparative approach is based on the methodological principle of “series of texts”, by grouping and collating a hundred works according to several variable parameters: the chronology, the theme or the grammatical tradition of the language in question.The first part of the study deals with the linguistic categorization and questions the nature of the non-finite verbal forms, especially the participle and its use in an analytical verbal form. The second part deals with the history of the participle from a more general point of view. Thus, after an overview of the problematic aspects of Greek and Latin grammarians, the analysis focuses on the treatment of the word-class in the grammars of the Romance languages. The third part focuses on the approaches and concepts used by the Renaissance grammarians to deal with compound tenses and on how they described and (re)-categorized the participle forms of these verbal tenses<br>El estudio presenta la historia de la clase del participio a través de un corpus de gramáticas de español, francés, italiano y portugués publicadas entre los siglos XV y XVIII.

La segunda parte propone una aproximacióna la historia del participio desde una perspectiva más general. Así pues, tras una cala en los aspectos problemáticos relacionados con el participio tratados por los gramáticos griegos y latinos, el análisis se centra en el tratamiento de la clase en las gramáticas de las lenguas romances.
