<p>South Africa&rsquo / s Language-in-Education Policy is one of additive multilingualism, but in reality this policy is not adhered to, in that most black children are being educated through the medium of English from Grade 4. This type of instruction affects the development of academic language proficiency in their primary language, as these children are not engaging in cognitively demanding tasks in their primary or first language. The Woodcock Mu&ntilde / oz Language Survey (WMLS) is a test to assess academic language proficiency in Additive Bilingual Education, and is extensively used in the United States of America (USA) for this purpose. It is important to note that the proposed study is a sub-study of a larger study, in which the original WMLS (American-English version) was adapted into English and Xhosa, to be used in South Africa to assess additive bilingual programmes. For this sub-study, the researcher was interested in examining the overall equivalence of the adapted English version of the WMLS. Owing to insufficient tests evaluating academic language proficiency in the South African context, the significance, as well as the overall aim, of the study is to ensure that the issues of group difference and item bias have been assessed to ensure that the adapted English version of the WMLS is suitable to be used across English first-language and Xhosa first-language speakers. Because this is a sub-study, the researcher (of the sub-study) has conducted an exploratory quantitative study with the use of Secondary Data. The researcher has used the framework of equivalence as a theoretical framework in order to examine the research question. Given the use of existing data, the procedures of the collection of the data by the researcher of the larger study have been outlined in the Methodology section of the present study. The sample consisted of 198 English and 197 Xhosa first-language speakers...</p>

<p>The diversity embodying South Africa has emphasized the importance and influence of language in education and thus the additive bilingual programme is being implemented in the Eastern Cape by the ABLE project in order to realize the South African Language in education policy (LEiP). In accordance with this, the Woodcock Munoz Language Survey (which specializes in measuring cognitive academic language proficiency) was chosen as one of the instruments to evaluate the language outcomes of the programme and was adapted into South African English and isiXhosa. The current study was a subset of the ABLE project, and was located within the bigger project dealing with the translation of the WMLS into isiXhosa and the successive research on the equivalence of the two language versions. This study evaluated the structural equivalence of the English and isiXhosa versions of the WMLS on matched sample groups (n= 150 in each language group). Thus secondary data analysis (SDA) was conducted by analyzing the data in SPSS as well as CEFA (Comprehensive Exploratory Factor Analysis). The original data set was purposively sampled according to set selection criteria and consists of English and isiXhosa first language learners. The study sought to confirm previous research by cross-validating the results of structural equivalence on two subscales, namely the Verbal Analogies (VA) and Letter-Word Identification (LWI) subscale. The research design reflects psychometric test theory and is therefore located in a bias and equivalence theoretical framework. The results of the exploratory factor analysis found that one can only accept structural equivalence in the first factor identified in the VA subscale, while structural equivalence was found in the factor for the LWI subscale. The use of scatter-plots to validate the results of the exploratory factor analysis indicated that one can tentatively accept these results. The study thus contributed to the literature on the translation of the WMLS, and the adaptation of language tests into the indigenous languages of South Africa,as well as additive bilingual programmes.</p>

La thèse présente une description géométrique d’un germe de famille générique déployant un champ de vecteurs réel analytique avec un foyer faible à l’origine et son complexifié : le feuilletage holomorphe singulier associé. On montre que deux germes de telles familles sont orbitalement analytiquement équivalents si et seulement si les germes de familles de difféomorphismes déployant la complexification de leurs fonctions de retour de Poincaré sont conjuguées par une conjugaison analytique réelle. Le “caractère réel” de la famille correspond à sa Z2-équivariance dans R^4, et cela s’exprime comme l’invariance du plan réel sous le flot du système laquelle, à son tour, entraîne que l’expansion asymptotique de la fonction de Poincaré est réelle quand le paramètre est réel. Le pullback du plan réel après éclatement par la projection monoidal standard intersecte le feuilletage en une bande de Möbius réelle. La technique d’éclatement des singularités permet aussi de donner une réponse à la question de la “réalisation” d’un germe de famille déployant un germe de difféomorphisme avec un point fixe de multiplicateur égal à −1 et de codimension un comme application de semi-monodromie d’une famille générique déployant un foyer faible d’ordre un. Afin d’étudier l’espace des orbites de l’application de Poincaré, nous utilisons le point de vue de Glutsyuk, puisque la dynamique est linéarisable auprès des points singuliers : pour les valeurs réels du paramètre, notre démarche, classique, utilise une méthode géométrique, soit un changement de coordonée (coordonée “déroulante”) dans lequel la dynamique devient beaucoup plus simple. Mais le prix à payer est que la géométrie locale du plan complexe ambiante devient une surface de Riemann, sur laquelle deux notions de translation sont définies. Après avoir pris le quotient par le relèvement de la dynamique nous obtenons l’espace des orbites, ce qui s’avère être l’union de trois tores complexes plus les points singuliers (l’espace résultant est non-Hausdorff). Les translations, le caractère réel de l’application de Poincaré et le fait que cette application est un carré relient les différentes composantes du “module de Glutsyuk”. Cette propriété implique donc le fait qu’une seule composante de l’invariant Glutsyuk est indépendante. / The thesis gives a geometric description for the germ of the singular holomorphic foliation associated with the complexification of a germ of generic analytic family unfolding a real analytic vector field with a weak focus at the origin. We show that two such germs of families are orbitally analytically equivalent if and only if the germs of families of diffeomorphisms unfolding the complexified Poincaré map of the singularities are conjugate by a real analytic conjugacy. The Z2-equivariance of the family of real vector fields in R^4 is called the “real character” of the system. It is expressed by the invariance of the real plane under the flow of the system which, in turn, carries the real asymptotic expansion of the Poincaré map when the parameter is real. After blowing up the singularity, the pullback of the real plane by the standard monoidal map intersects the foliation in a real Möbius strip. The blow up technique allows to “realize” a germ of generic family unfolding a germ of diffeomorphism of codimension one and multiplier −1 at the origin as the semi-monodromy of a generic family unfolding an order one weak focus. In order to study the orbit space of the Poincaré map, we perform a trade-off between geometry and dynamics under the Glutsyuk point of view (where the dynamics is linearizable near the singular points): in the resulting “unwrapping coordinate” the dynamics becomes much simpler, but the price we pay is that the local geometry of the ambient complex plane turns into a much more involved Riemann surface. Over the latter, two notions of translations are defined. After taking the quotient by the lifted dynamics we get the orbit space, which turns out to be the union of three complex tori and the singular points (this space is non- Hausdorff). The Glutsyuk invariant is then defined over annular-like regions on the tori. The translations, the real character and the fact that the Poincaré map is the square of the semi-monodromy map, relate the different components of the Glutsyuk modulus. That property yields only one independent component of the Glutsyuk invariant.

Multilingual terminological resources do not always include valid equivalents of legal terms for two main reasons. Firstly, legal systems can differ from one language community to another and even from one country to another because each has its own history and traditions. As a result, the non-isomorphism between legal and linguistic systems may render the identification of equivalents a particularly challenging task. Secondly, by focusing primarily on the definition of equivalence, a notion widely discussed in translation but not in terminology, the literature does not offer solid and systematic methodologies for assigning terminological equivalents. As a result, there is a lack of criteria to guide both terminologists and translators in the search and validation of equivalent terms. This problem is even more evident in the case of predicative units, such as verbs. Although some terminologists (L‘Homme 1998; Lerat 2002; Lorente 2007) have worked on specialized verbs, terminological equivalence between units that belong to this part of speech would benefit from a thorough study. By proposing a novel methodology to assign the equivalents of specialized verbs, this research aims at defining validation criteria for this kind of predicative units, so as to contribute to a better understanding of the phenomenon of terminological equivalence as well as to the development of multilingual terminography in general, and to the development of legal terminography, in particular. The study uses a Portuguese-English comparable corpus that consists of a single genre of texts, i.e. Supreme Court judgments, from which 100 Portuguese and 100 English specialized verbs were selected. The description of the verbs is based on the theory of Frame Semantics (Fillmore 1976, 1977, 1982, 1985; Fillmore and Atkins 1992), on the FrameNet methodology (Ruppenhofer et al. 2010), as well as on the methodology for compiling specialized lexical resources, such as DiCoInfo (L‘Homme 2008), developed in the Observatoire de linguistique Sens-Texte at the Université de Montréal. The research reviews contributions that have adopted the same theoretical and methodological framework to the compilation of lexical resources and proposes adaptations to the specific objectives of the project. In contrast to the top-down approach adopted by FrameNet lexicographers, the approach described here is bottom-up, i.e. verbs are first analyzed and then grouped into frames for each language separately. Specialized verbs are said to evoke a semantic frame, a sort of conceptual scenario in which a number of mandatory elements (core Frame Elements) play specific roles (e.g. ARGUER, JUDGE, LAW), but specialized verbs are often accompanied by other optional information (non-core Frame Elements), such as the criteria and reasons used by the judge to reach a decision (statutes, codes, previous decisions). The information concerning the semantic frame that each verb evokes was encoded in an xml editor and about twenty contexts illustrating the specific way each specialized verb evokes a given frame were semantically and syntactically annotated. The labels attributed to each semantic frame (e.g. [Compliance], [Verdict]) were used to group together certain synonyms, antonyms as well as equivalent terms. The research identified 165 pairs of candidate equivalents among the 200 Portuguese and English terms that were grouped together into 76 frames. 71% of the pairs of equivalents were considered full equivalents because not only do the verbs evoke the same conceptual scenario but their actantial structures, the linguistic realizations of the actants and their syntactic patterns were similar. 29% of the pairs of equivalents did not entirely meet these criteria and were considered partial equivalents. Reasons for partial equivalence are provided along with illustrative examples. Finally, the study describes the semasiological and onomasiological entry points that JuriDiCo, the bilingual lexical resource compiled during the project, offers to future users. / Les ressources multilingues portant sur le domaine juridique n‘incluent pas toujours d‘équivalents valides pour deux raisons. D‘abord, les systèmes juridiques peuvent différer d‘une communauté linguistique à l‘autre et même d‘un pays à l‘autre, car chacun a son histoire et ses traditions. Par conséquent, le phénomène de la non-isomorphie entre les systèmes juridiques et linguistiques rend difficile la tâche d‘identification des équivalents. En deuxième lieu, en se concentrant surtout sur la définition de la notion d‘équivalence, notion largement débattue en traductologie, mais non suffisamment en terminologie, la littérature ne propose pas de méthodologies solides et systématiques pour identifier les équivalents. On assiste donc à une absence de critères pouvant guider tant les terminologues que les traducteurs dans la recherche et la validation des équivalents des termes. Ce problème est encore plus évident dans le cas d‘unités prédicatives comme les verbes. Bien que certains terminologues (L'Homme, 1998; Lorente et Bevilacqua 2000; Costa et Silva 2004) aient déjà travaillé sur les verbes spécialisés, l‘équivalence terminologique, en ce qui concerne ce type d‘unités, bénéficierait d‘une étude approfondie. En proposant une méthodologie originale pour identifier les équivalents des verbes spécialisés, cette recherche consiste donc à définir des critères de validation de ce type d‘unités prédicatives afin de mieux comprendre le phénomène de l‘équivalence et aussi améliorer les ressources terminologiques multilingues, en général, et les ressources terminologiques multilingues couvrant le domaine juridique, en particulier. Cette étude utilise un corpus comparable portugais-anglais contenant un seul genre de textes, à savoir les décisions des cours suprêmes, à partir duquel 100 verbes spécialisés ont été sélectionnés pour chaque langue. La description des verbes se base sur la théorie de la sémantique des cadres (Fillmore 1976, 1977, 1982, 1985; Fillmore and Atkins 1992), sur la méthodologie de FrameNet (Ruppenhofer et al. 2010), ainsi que sur la méthodologie développée à l‘Observatoire de linguistique Sens-Texte pour compiler des ressources lexicales spécialisées, telles que le DiCoInfo (L‘Homme 2008). La recherche examine d‘autres contributions ayant déjà utilisé ce cadre théorique et méthodologique et propose des adaptations objectives du projet. Au lieu de suivre une démarche descendante comme le font les lexicographes de FrameNet, la démarche que nous décrivons est ascendante, c‘est-à-dire, pour chaque langue séparément, les verbes sont d‘abord analysés puis regroupés par cadres sémantiques. Dans cette recherche, chacun des verbes « évoque » un cadre ou frame, une sorte de scénario conceptuel, dans lequel un certain nombre d‘acteurs obligatoires (core Frame Elements) jouent des rôles spécifiques (le rôle de juge, le rôle d‘appelant, le rôle de la loi). Mis en discours, les termes sont souvent accompagnés d‘autres renseignements optionnels (non-core Frame Elements) comme ceux des critères utilisés par le juge pour rendre une décision (des lois, des codes, d‘autres décisions antérieures). Tous les renseignements concernant les cadres sémantiques que chacun des verbes évoque ont été encodés dans un éditeur xml et une vingtaine de contextes illustrant la façon spécifique dont chacun des verbes évoque un cadre donné ont été annotés. Les étiquettes attribuées à chaque cadre sémantique (ex. [Compliance], [Verdict]) ont servi à relier certains termes synonymes, certains termes antonymes ainsi que des candidats équivalents. Parmi les 200 termes portugais et anglais regroupés en 76 cadres, 165 paires de candidats équivalents ont été identifiés. 71% des paires d‘équivalents sont des équivalents parfaits parce que les verbes évoquent le même scénario conceptuel, leurs structures actancielles sont identiques, les réalisations linguistiques de chacun des actants sont équivalentes, et les patrons syntaxiques des verbes sont similaires. 29% des paires d‘équivalents correspondent à des équivalents partiels parce qu‘ils ne remplissent pas tous ces critères. Au moyen d‘exemples, l‘étude illustre tous les cas de figure observés et termine en présentant les différentes façons dont les futurs utilisateurs peuvent consulter le JuriDiCo, la ressource lexicale qui a été compilée pendant ce projet.

This study formed part of a larger project that is concerned with the adaptation of a test of cognitive academic language proficiency, the Woodcock Muñoz Language Survey (WMLS). The WMLS has been adapted from English into isiXhosa and the present study is located within the broader study that is concerned with establishing overall equivalence between the two language versions of the WMLS. It was primarily concerned with the Verbal Analogies (VA) scale. Previous research on this scale has demonstrated promising results, but continues to find evidence of some inequivalence. This study aimed to cross-validate previous research on the two language versions of the WMLS and improve on methodological issues by employing matched groups. It drew upon an existing dataset from the larger research project. The study employed a monolingual matched two-group design consisting of 150 mainly English speaking and 149 mainly isiXhosa learners in grades 6 and 7. This study had two sub aims. The first was to investigate item bias by identifying DIF items in the VA scale across the isiXhosa and English by conducting a logistic regression and Mantel-Haenszel procedure. Five items were identified by both techniques as DIF. The second sub aim was to evaluate construct equivalence between the isiXhosa and English versions of the WMLS on the VA scale by conducting a factor analysis on the tests after removal of DIF items. Two factors were requested during the factor analysis. The first factor displayed significant loadings across both language versions and was identified as a stable factor. This was confirmed by the Tucker&rsquo;s Phi and scatter plot. The second factor was stable for the English version but not for the isiXhosa version. The Tucker&rsquo;s phi and scatter plot indicated that this factor is not structurally equivalent across the two language versions / Magister Artium (Psychology) - MA(Psych)

Le ciment est la principale source des impacts sur l'environnement de l'utilisation du matériau béton. Afin d'optimiser ce dernier d'un point de vue environnemental, il est nécessaire de réduire son dosage en ciment. Cela peut être entrepris en remplaçant une partie du ciment par des additions minérales lors de sa fabrication.Ces travaux de thèse visent à étudier les phénomènes physico-chimiques ayant lieu lors du processus de carbonatation de bétons à forts taux de remplacement du ciment par des additions minérales ainsi que leur résistance à ce type d'attaque.Une campagne expérimentale a été menée sur des bétons de référence préparés à base de ciments courants et sur des Écobétons préparés en substituant une partie du ciment par des cendres volantes ou du laitier de haut-fourneau. Les différentes études menées portent sur la durabilité des Écobétons vis-à-vis de la carbonatation, sur l'équivalence de performances des Écobétons avec celles des bétons de référence, et sur les paramètres de composition et de microstructure contrôlant la cinétique de carbonatation. La carbonatation a été étudiée en conditions accélérées et naturelles. Les résultats montrent que les Écobétons à forts taux de substitution du ciment par des cendres (50 %) ou du laitier (75 %) pourraient remplacer, dans certains cas, les bétons conformes à la norme en vigueur.En complément à l'étude expérimentale, des simulations numériques du couplage hydratation/séchage ont été menées en vue de déterminer l'effet du séchage sur les propriétés contrôlant la cinétique de carbonatation accélérée des bétons étudiés (la porosité, la quantité de Portlandite et le degré de saturation en eau liquide). Les résultats montrent que la cinétique de séchage augmente avec le taux de substitution du ciment par des additions. Ils remettent aussi en cause la pertinence du préconditionnement des échantillons lors de l'essai de carbonatation accélérée mené selon la norme française XP P 18-458 actuellement en vigueur.
