Cette thèse prend ses racines dans la tradition sémantique montagovienne et dynamique standard. L’objet est les conditions dans lesquelles un syntagme nominal peut agir comme antécédent d'une expression anaphorique. Le travail porte sur l'accessibilité des référents de discours dans un système formel de la sémantique dynamique. Le cadre choisi est celui proposé par De Groote, type théorique Dynamic Logic (TTDL) car il fait appel à des outils mathématiques et logiques standards, qui permettent de conserver le principe de compositionnalité. Nous étendons la couverture de la gestion de l’accessibilité des référents dans TTDL à deux cas naturellement problématique pour les théories sémantiques dynamiques classiques, en particulier, l'anaphore sous la double négation et les modalités. Une adaptation est définie pour chaque cas et enfin, l'intégration des différentes solutions est proposée, ce qui montre la souplesse de TTDL. / This thesis has its roots in the standard Montagovian and dynamic semantic tradition. The subject is conditions under which a noun phrase may act as antecedent of a particular anaphoric expression. The work thesis deals with the accessibility of discourse referents using a formal system of dynamic semantics. The framework used is the one proposed by De Groote, Type Theoretic Dynamic Logic (TTDL) because it follows the Montagovian tradition and only makes use of standard mathematical and logical tools which allows to maintain compositionnality. We extend the coverage of TTDL to cases which are naturally problematic for classical dynamic semantic theories. In particularly, this thesis aims to extend TTDL's coverage of the accessibility of referents to two exceptions of classical dynamic theories, namely anaphora under double negation and modality. An adaptation is defined for each case and finally, an integration of various solutions is proposed, which shows the flexibility of TTDL

The purpose of this study is a comparison of the socio-economic status with the school status of the seventh, eighth, and ninth-grade pupils of the Montague, Texas, public schools. In this study the socio-economic status is interpreted as meaning the position that the individual, or family, occupies with reference to average standards based on the home status indexes.

I present a simple Simultaneous Abstraction Calculus, where the familiar lambda-abstraction over single variables is replaced by abstraction over whole sets of them. Terms are applied to partial assignments of objects to variables. Variants of the system are investigated and compared, with respect to their semantic and proof theoretic properties. The system overcomes the strict ordering requirements of the standard lambda-calculus,and is shown to provide the kind of "non-selective" binding needed for Dynamic Montague Grammar and Discourse Representation Theory. It is closely related to a more complex system, due to Peter Aczel and Rachel Lunon, and can be used for Situation Theory in a similar way. I present versions of these theories within an axiomatic, property-theoretic framework, based on Aczels Frege Structures. The aim of this work is to provide the means for integrating various semantic theories within a formal framework,so that they can share what is common between them, and adopt from each other what is compatible with them.

Health is a primary objective of modern education. It was named as the first of the seven cardinal principles of education. Over a period of years the health and safety of the school children have gradually become more firmly fixed as a part of the school program. Modern schools, when adequately staffed and administered, provide experiences in healthful daily living, an opportunity to become acquainted with good health services, a chance to learn something about the care of ones own body, the maintenance of health, and the prevention of disease. Thus the schools have come to contribute to community health through their planned programs of health service and through cooperation with other health and safety agencies.

Historical gold mine tailings at several sites in Nova Scotia, Canada are publicly accessible and may pose a threat to human and ecosystem health because of high arsenic (As) concentrations in the tailings (max 25 wt.%) and associated pore waters (up to 100 mg/L). Two of these sites, Montague and Goldenville, are under consideration for remediation. Similar tailings sites have been cleaned up by covering the mine wastes with soil. However, the tailings at Montague and Goldenville have been weathering for at least 70 years, leading to a wide range of As-bearing secondary minerals which may dissolve under a soil cover, releasing As to local waters. The challenge of remediating these heterogeneous tailings lies in the different Eh-pH niches in which iron arsenates (oxidizing, acidic), calcium-iron-arsenates (oxidizing, alkaline), and sulfides (reducing) are stable. The main objectives of this study were to: 1) characterize pre-remediation geochemical controls on As mobility in subsurface tailings; 2) establish hydrogeological influences on As mobility; and 3) identify geochemical changes that result when a low organic soil cover is applied to the tailings. Pore water measurements were combined with bulk chemistry, scanning electron microscopy, and synchrotron micro-X-ray diffraction analyses, which were used to characterize the mineralogical composition of the tailings. Groundwater and surface water flow regimes throughout the tailings were defined through the use of piezometers and hydraulic conductivity measurements. Laboratory leaching experiments were used to assess the effects of a soil cover on the tailings. Variable weathering conditions over time have resulted in a continuum of saturation and redox environments and a range of As hosts in the tailings. In some areas, tailings pore waters are mixing with stream waters leading to As transport beyond the tailings. Applying a low organic soil cover does not induce reducing conditions in the tailings or cause dissolved As concentrations to increase compared to field pore water concentrations. This type of soil cover is effective in slowing sulfide mineral oxidation while maintaining stable conditions for secondary As-phases. The results of this research can be used to inform remediation decisions and guide ongoing environmental management of historical gold mine sites. / Thesis (Ph.D, Geological Sciences & Geological Engineering) -- Queen's University, 2014-06-04 10:22:43.838

The problem of this thesis is to examine the Gilmer-Aikin plan as it will affect the Montague County, Texas, schools in order to ascertain whether present inequities, if any, will be corrected, and to present additional remedial proposals if needed.

Le but de cette thèse est de caractériser ce qui se passe à la jonction entre le système linguistique et le système conceptuel de notre esprit. Nous défendons la thèse selon laquelle le système linguistique de notre esprit encode des règles permettant de manipuler directement des représentations mentales dotées d'un contenu sémantique. Après avoir examiné les propositions des formalistes du début du XXe siècle (Frege, Russell), des sémanticiens formels (Montague, Lewis) et de la pragmatique de Grice, nous développons notre propre théorie. Nous nous servons des travaux de Chomsky pour développer une théorie unifiée de l'interface langage/pensée dont nous montrons qu'elle rend compte des données neuropsychologiques concernant le traitement linguistique. Nous testons alors notre théorie en l'appliquant au problème des implicatures enchâssées et terminons en signalant ses applications possibles en TALN, à la clarification de l'hypothèse du langage de la pensée et à la distinction sémantique/pragmatique.
