Monadic Parsing in Haskell

This paper is a tutorial on defining recursive descent parsers in Haskell. In the spirit of one-stop shopping, the paper combines material from three areas into a single source. The three areas are functional parsers, the use of monads to structure functional programs, and the use of special syntax for monadic programs in Haskell. More specifically, the paper shows how to define monadic parsers using do notation in Haskell. The paper is targeted at the level of a good undergraduate student who is familiar with Haskell, and has completed a grammars and parsing course. Some knowledge of functional parsers would be useful, but no experience with monads is assumed.

"Dal 1976 al 2006: livellazione semantica del valore dei tempi e dei modi nella didattica dell'italiano L2"

In the paper we present some of the most significant tendencies in Italian LS teaching in the past thirty years (1976 -2006). All of the simplifications concern Italian Verbal Moods: imperative, gerundio presente and gerundio passato, past and present infinitive, congiuntivo trapassato and condizionale composto. In our analysis we want to compare certain features present in the most recent Italian LS grammars with those of the seventies and nineties of the past century.

On L2 grammar and processing: the case of oblique relative clauses and the Null-Prep phenomenon

This dissertation investigates the acquisition of oblique relative clauses in L2 Spanish by English and Moroccan Arabic speakers in order to understand the role of previous linguistic knowledge and its interaction with Universal Grammar on the one hand, and the relationship between grammatical knowledge and its use in real-time, on the other hand. Three types of tasks were employed: an oral production task, an on-line self-paced grammaticality judgment task, and an on-line self-paced reading comprehension task. Results indicated that the acquisition of oblique relative clauses in Spanish is a problematic area for second language learners of intermediate proficiency in the language, regardless of their native language. In particular, this study has showed that, even when the learners’ native language shares the main properties of the L2, i.e., fronting of the obligatory preposition (Pied-Piping), there is still room for divergence, especially in production and timed grammatical intuitions. On the other hand, reaction time data have shown that L2 learners can and do converge at the level of sentence processing, showing exactly the same real-time effects for oblique relative clauses that native speakers had. Processing results demonstrated that native and non-native speakers alike are able to apply universal processing principles such as the Minimal Chain Principle (De Vincenzi, 1991) even when the L2 learners still have incomplete grammatical representations, a result that contradicts some of the predictions of the Shallow Structure Hypothesis (Clahsen & Felser, 2006). Results further suggest that the L2 processing and comprehension domains may be able to access some type of information that it is not yet available to other grammatical modules, probably because transfer of certain L1 properties occurs asymmetrically across linguistic domains. In addition, this study also explored the Null-Prep phenomenon in L2 Spanish, and proposed that Null-Prep is an interlanguage stage, fully available and accounted within UG, which intermediate L2 as well as first language learners go through in the development of pied-piping oblique relative clauses. It is hypothesized that this intermediate stage is the result of optionality of the obligatory preposition in the derivation, when it is not crucial for the meaning of the sentence, and when the DP is going to be in an A-bar position, so it can get default case. This optionality can be predicted by the Bottleneck Hypothesis (Slabakova, 2009c) if we consider that these prepositions are some sort of functional morphology. This study contributes to the field of SLA and L2 processing in various ways. First, it demonstrates that the grammatical representations may be dissociated from grammatical processing in the sense that L2 learners, unlike native speakers, can present unexpected asymmetries such as a convergent processing but divergent grammatical intuitions or production. This conclusion is only possible under the assumption of a modular language system. Finally, it contributes to the general debate of generative SLA since in argues for a fully UG-constrained interlanguage grammar.

É possível acompanhar o luto? Envolvimento associativo a famílias vulneráveis em face da perda de seres íntimos

Partindo da análise das lógicas de ação solidária, propõem-se com esta comunicação refletir sobre os princípios que poderão ter contribuído para uma alteração das sensibilidades e compaixões dos cidadãos relativamente aos quadros sociais do sofrimento humano, dando lugar a diferentes quadrantes de operações criticas na prossecução de um bem comum. O sentimento de vulnerabilidade, associado às “vítimas de luto”, poderá ser um dos fatores promotores de diferentes interpretações críticas e manifestações coletivas de indignação que é denunciada publicamente pelas associações do luto, originando controvérsias, disputas e conflitos. As controvérsias públicas, que diferentes gramáticas de motivação conduzem os atores a associar-se, em consequência do cruzamento das intenções individuais e coletivas, perseguem um fim comum sujeito a um acordo (umas vezes mais precário, outras vezes menos precário). O tipo de acordo e as modalidades de cooperação da ação são aspetos fundamentais para perceber, por um lado qual a gramática política em que se baseiam na generalidade as associações, que existem atualmente na sociedade portuguesa, e por outro lado, as novas práticas sociais por elas desenvolvidas enformadas pelos princípios da solidariedade e participação. Apresentar-se-ão alguns dados preliminares de um estudo, no sentido de compreender e explicar os diferentes regimes de envolvimento associativo em torno do luto, partindo do singular para o geral: o regime familiar, o regime de plano e o regime público, diferenciados em função do julgamento feito pelo atores em situação.

Londres et les Britanniques dans l’ancienne grammaticographie du Portugais comme langue étrangère (XVIIe- XIXe siècles)

Observant le corpus des grammaires de portugais langue étrangère, depuis la deuxième moitié du XVIIe siècle, nous constatons que Londres a été une capitale éditoriale du monde grammatical portugais et les Britanniques (étudiants et commerçants) un public cible privilégié. L’œuvre A Portuguez Grammar : or, Rules shewing the True and Perfect way to learn the said language (1662) – la première publication grammaticale connue de portugais langue étrangère – a été publiée à Londres, lors du mariage royal de l’infante portugaise Catherine de Bragance et Charles II d’Angleterre, afin de servir, selon son auteur, le militaire français Monsieur de la Molière : “a deux sortes de personne en Angleterre, aux gens de commerce (…) & aux gens de Cour” (“to two sorts of Persons in England : to people of Traffique and Commerce (…) And to Persons of the Court”). La production et la circulation de grammaires de portugais comme langue étrangère écrites en anglais et publiées à Londres continuent pendant les XVIIIe et XIXe siècles ; ville où ont été commercialisées et exportées des œuvres grammaticales portugaises comme celles de J. Castro (1731), António Vieira (1786), Richard Woodhouse (1815), Luís Francisco Midosi (1832), Alfred Elwes (1876), Charles Henry Wall (1882). Notre propos dans cette étude est, d’abord, d’analyser ce mouvement grammatical luso-britannique, notamment un ensemble de grammaires de portugais produites dans l’espace anglophone. De plus, nous estimons contribuer à l’étude des anciennes grammaires de portugais comme langue étrangère dans le cadre de l’historiographie linguistique canonique, partant du fait que ces œuvres font partie de l’historie de la grammaire des vernaculaires européens.
