Aprendizaje léxico y desarrollo de la gramática: vocabulario verbal, aceleración morfológica y complejidad sintáctica

This paper studies the initial development of certain language components. More precisely, we analyse the relation between three aspects that are closely involved in the grammar of the verb: morphological productivity, syntactic complexity, and verb vocabulary learning. The study is based on data about the relationship between lexical development and grammatical development, and also on proposals that a critical mass of vocabulary is needed in order to develop a grammatical component. The sample comprised six subjects who are monolingual or bilingual in Catalan andlor Spanish. Results show a morphological spurt some time afer the learning of a certain quantity of verbs. Moreover, syntactic complexity is only evident some months after this morphological spurt

L'ús dels clítics pronominals del català i la seva adquisició per parlants de romanès i de tagal

The thesis L’ús dels clítics pronominals del català i la seva adquisició per parlants de romanès i de tagal [The use of pronominal clitics in Catalan and their acquisition by Romanian and Tagalog speakers] analyzes the mechanisms of transfer from the L1 in the process of acquisition of Catalan (L2) in two groups of learners, one of which has Romanian and the other Tagalog as their native language. Our study lends support to the idea of transfer from the L1 to a second language in general, and, in particular, within the process of acquisition of pronominal clitics from a Romance language (Catalan). The results show that the differences between the two groups are statistically significant and are attributable to the characteristics of the L1. Moreover, starting from a detailed description of the grammar of pronominal clitics in the three languages involved, we define the specific grammatical aspects of the Tagalog and Romanian languages that can have an influence on certain productions and on certain errors in the use of pronominal clitics in Catalan, within the process of acquisition of this Romance language as L2. In the theoretical domain, we started from studies on functional markedness to determine four reference terms that allowed us to carry out a systematized study of the difficulties in acquisition of the use of Catalan clitic pronouns according to their complexity and their degree of grammaticalization.

Dissolution of Dynamic Electronic Institutions, a first approach: Relevant factors and causes

In the context of the digital business ecosystems, small organizations cooperate between them in order to achieve common goals or offer new services for expanding their markets. There are different approaches for these cooperation models such as virtual enterprises, virtual organizations or dynamic electronic institutions which in their lifecycle have in common a dissolution phase. However this phase has not been studied deeply in the current literature and it lacks formalization. In this paper a first approach for achieving and managing the dissolution phase is proposed, as well as a CBR process in order to support it in a multi-agent system

The Construction of grammar concepts at secondary school

In this study we make a general research question [1] and two specific ones [2] i [3]: [1] How can we establish a new model for teaching and learning grammar? [2] How metalinguistic knowledge is built within this model? [3] How can we elaborate an analysis model for exploring grammar knowledge?
