This paper explores the role played by cognitive and processing limitations in language acquisition and the relevance of bilingual rst language acquisition for the ongoing debate on the ontogeny of functional categories. 1 Deening bilingual rst language acquisition Over the past twenty years the eld of language acquisition studies has beneetted enormously from the shift from an English-centred ...

While demonstratives and other determiner-like words in English are part of the functional system, their Japanese counterparts are simple lexical categories. The semantic theory (e.g. Brown & Fraser 1963) predicts that these elements must emerge at a later stage in both languages since they denote relatively abstract and complex meanings; whereas Radford's (1990) maturational theory makes no su...

Homology-based approaches are often used for the annotation of microbial communities, providing functional profiles that are used to characterize and compare the content and the functionality of microbial communities. Metagenomic reads are the starting data for these studies, however considerable differences are observed between the functional profiles-built from sequencing reads produced by di...

All three properties are not instantiated in Bulgarian. Only the first two properties are explicitly taught in English classrooms in Bulgaria, while the third is not. A Truth Value Judgement Task, a guided composition task and a proficiency test were administered to 112 Bulgarian learners of English and 24 native speaker controls. Results indicate that L2 learners at all proficiency levels are ...

Ready access to emerging databases of gene annotation and functional pathways has shifted assessments of differential expression in DNA microarray studies from single genes to groups of genes with shared biological function. This paper takes a critical look at existing methods for assessing the differential expression of a group of genes (functional category), and provides some suggestions for ...

In this paper I argue that syntactic categories are not part of UG but are acquired during first language acquisition as a result of doubling effects. In short, it is argued that a semantic operator OpF can only be (re-)analysed as a formal feature (that may yield a functional projection) if the language input exhibits doubling effects with respect to F. After providing a theoretical motivation...
