Σ _1^1 in Every Real in a Σ _1^1 Class of Reals Is Σ _1^1
We rst prove a theorem about reals (subsets of N) and classes of reals: If a real X is 1 in every member G of a nonempty 1 1 class K of reals then X is itself 1. We also explore the relationship between this theorem, various basis results in hyperarithmetic theory and omitting types theorems in !-logic. We then prove the analog of our rst theorem for classes of reals: If a class A of reals is...
متن کاملExploring Sub-Disciplinary Variations and Generic Structure of Applied Linguistics Research Article Introductions Using CARS Model
This paper explores sub-disciplinary variations and generic structure of research article introductions (RAIs) within three sub-disciplines of applied linguistics (AL); namely, English for Specific Purposes (ESP), Psycholinguistics, and Sociolinguistics, using Swales’(1990) CARS model. The corpus consisted of 90 RAIs drawn from a wide range of refereed journals in the corresponding sub-discipli...
متن کاملNTP Update
The use of heat treatment for the removal of non-specific effects in the direct radioimmunoassay of human circulatory CEA has been widely adopted have shown the existence of heat-labile determinants on CEA which may be destroyed by this assay technique. Heat-labile antigens appeared to be shared between CEA isolated from tumour and normal colon whilst the heat-stable antigens appeared to be mor...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولValued Difference Fields and Ntp
We show that the theory of the non-standard Frobenius automorphism, acting on an algebraically closed valued field of equal characteristic 0, is NTP2. More generally, in the contractive as well as in the isometric case, we prove that a σ-Henselian valued difference field of equicharacteristic 0 is NTP2, provided both the residue difference field and the value group (as an ordered difference gro...
