Boruta, Luc. "Indicators of allophony and phonemehood". Paris 7, 2012. http://www.theses.fr/2012PA070089.
Texto completoAlthough we are only able to distinguish between a finite, small number of sound categories -a given language's phonemes- no two sounds are actually identical in the messages we receive. Given the pervasiveness of sound-altering processes across languages -and the fact that every language relies on its own set of phonemes- what kind of cues may, for example, English-learning infants rely on to learn that [siŋki ] and [θiŋki ] (i. E. Sinking thinking) can not refer to the same action ? The work presented in this dissertation builds upon the line of computational studies initiated by Peperkamp et al; (2006), wherein research efforts have been concentrated on the definition of sound-to-sound dissimilarity measures indicating which sounds are realizations of the same phoneme. We show that solving Peperkamp et al. 's task does not yield a full answer to the problem of the discovery of phonemes, as formal and empirical limitations arise from its pairwise formulation. We proceed to circumvent these limitations, reducing the task of the acquisition of phonemes to a partitioning-clustering problem and using multidimensional scaling to allow for the use of individual phones as the elementary objects. The results of various classification and clustering experiments consistently indicate that effective indicators of allophony are not necessarily effective indicators of phonemehood. Altogether, the computational results we discuss suggest that allophony and phonemehood can only be discovered from acoustic, temporal, distributionall, or lexical indicators at low allophonic complexities, i. E. When -on average- phonemes do not have many allophones in the quantized representation of the input

Allophane and imogolite are nanosized aluminosilicate minerals and strongly control the physical and chemical behavior of soil. They hold promise for use in technological applications. In nature, allophane and imogolite are often observed together in varying proportions. Similarly, laboratory synthesis by various methods usually does not result in pure phases. These observations suggest they form at the same time, at a wide range of solution chemical conditions. It remains unclear what factors determine how and when these phases form in solution, which limits our understanding of their occurrence in nature and the laboratory. The objective of this study is to understand and explain what solution chemical and physical conditions control the formation of synthetic imogolite and allophane. We did this by utilizing a unique approach where we systematically varied starting conditions of formation of these particles, and then used analytic and statistical methods to develop a model that describes the relationship between each of the starting conditions – concentration, size, pH, atomic ratios, and hydrolysis ratios, and how those affect the phase abundance of the particles.

This work presents the description of some phonological aspects in the southern region of Goiás State, in the cities of Orizona, Pires do Rio, Ipameri, Catalão, Três Ranchos, Corumbaíba, Buriti Alegre, Caldas Novas, Mineiros, Rio Verde, Jataí, Itumbiara, Cachoeira Dourada, Quirinópolis, São Simão, Edéia, Paraúna and Vianópolis. The analysis resulted from the answers given in the ALINGO (Linguistic Atlas of Goiás). For pedagogical reasons, these aspects were separated regarding the vowels, the syllables and the consonants. The observations performed about the vowels were related to the phonological possibilities for the phoneme /o/ in pretonic position, which analyzed the different productions of words like “armpit” (sovaco), “ankle” (tornozelo), “sob” (soluço) and “dew” (orvalho). The issue concerning the syllables approaches the nasalization and the oralization of the syllable “-gem” in the end of the words. In this analysis, it was used the realization of “rain drought” (estiagem), “swill” (lavagem) and “pod” (vagem). The chapter about the consonants addressed the oscillation between the employment of /g/ and /k/ in the word “corncob” (sabugo) in the south of Goiás speech. As theoretical fundamentals of the hypothesis worked in each phenomenon, it were used, mainly, the Historical Grammar and the Descriptive Linguistics. To introduce these descriptive chapters presented and explained the concepts of vowel sounds, syllable and consonantal sounds in order to facilitate the comprehension of occurred phenomena. Before the descriptive analysis, in the first chapter, there is a historical background of studies related to the sounds, which presents the development of the main theories in this scope, including the ones used as theoretical basis.
Este trabalho apresenta a descrição de alguns aspectos fonológicos na região sul do estado de Goiás, nas cidade de Orizona, Pires do Rio, Ipameri, Catalão, Três Ranchos, Corumbaíba, Buriti Alegre, Caldas Novas, Mineiros, Rio Verde, Jataí, Itumbiara, Cachoeira Dourada, Quirinópolis, São Simão, Edéia, Paraúna e Vianópolis. As análises partiram de respostas dadas ao questionário do ALINGO – Atlas linguístico de Goiás. Por questões didáticas esses aspectos foram separados quanto às vogais, às sílabas e às consoantes. As observações realizadas sobre as vogais se relacionaram às possibilidades fonológicas para o fonema /o/ em posição pré-tônica, que analisou as diferentes produções das palavras “sovaco”, “tornozelo”, “soluço” e “orvalho”. A questão referente às sílabas aborda a nasalização e a oralização da sílaba “-gem” em final de palavras. Para essa análise foram utilizadas as realizações de “estiagem”, “lavagem” e “vagem” O capítulo a respeito das consoantes tratou da oscilação entre o emprego de /g/ e /k/ na palavra “sabugo” no falar do sul de Goiás. Como fundamentação teórica das hipóteses trabalhadas em cada um dos fenômenos utilizaram-se, principalmente, aspectos da Gramática Histórica e da Linguística descritiva. Para introduzir esses capítulos descritivos, foram apresentados e explanados os conceitos dos sons vocálicos, das sílabas e dos sons consonantais, a fim de facilitar a compreensão dos fenômenos ocorridos. Antes das análises descritivas, no primeiro capítulo, há um percurso histórico dos estudos referentes aos sons, que apresenta o desenvolvimento das principais teorias desse âmbito, inclusive das que foram utilizadas como aporte teórico.

Texto completoThis dissertation investigates imitation in speech, which is the general tendency shown by a speaker to become more similar to another speaker in the way they speak. Many of us have experienced this while talking to someone who is speaking the same language but with a different accent. Conversing with such a person can affect some characteristics of our speech, so that we come to sound more like them. Imitation in speech has been very extensively studied, especially over recent years. To contribute to this line of research we provide an account of imitation in speech at the allophonic level, that is at the level of the possible phonetic realisations of a phoneme. We are interested in whether imitation of the sound of a given phoneme in a particular word position can influence the other possible realisations of that phoneme in the same word position. We are also interested in determining whether imitation of a speech sound in a particular word position for a given phoneme can affect the realisations of that phoneme in a different word position

Texto completoDans un premier temps, une étude sur des composés synthétiques analogues aux aluminosilicates a permis d'approfondir nos connaissances sur la structure et les mécanismes de formation des imogolites et allophanes. La synthèse de nanotubes de type imogolite (Si-imogolite et Ge-imogolite) a pu être optimisée ouvrant ainsi les portes à de potentielles applications industrielles. Enfin, notre étude a permis de mettre en avant le rôle important des nanoparticules naturelles sur la dynamique du Ni dans un andosol de la Réunion. Ainsi, près de 80% du Ni est lié aux aluminosilicates structurés à courte distance.

Texto completoEvery year a considerable number of recently immigrated students attend the schools of Quebec. For these students, the risk of facing socio-educational difficulties is potentially high, particularly for those who are allophones and living in deprivation. Several studies highlight success of socio-educational adaptation of numerous students, but it still remains that others have difficulties and it is capital to look into better understanding how to best support them through this journey. The general objective of this research is to describe the phenomenon of educational resilience in young allophones in elementary schools who have recently immigrated in order to know how to better foster and support their social integration and educational success. The concept of resilience was used as the theoretical framework in order to capture the systemic character of socio-educational integration of these immigrant students, who at their arrival do not master the French language. The results of the data analysis show that the characteristics that have supported the socio-educational adaptation of the students we have met with, can be organized in four categories: the student (educational motivation and the importance placed on education in general, the will to learn French), his/her family environment (parents’ interest in the child’s education, parents’ positive discourse in regards to education), his/her environment outside the family (places of worship and spaces for socio-cultural development, community organisations, significant adults who can support the child’s resilience) and his/her school experience (involved and available teachers, who inspire trust and are appropriately equipped, positive psychosocial climate in class and in school).
