Du tout au rien:libre-choix et polarité negative

This monograph proposes a general model for the analysis of polysemy. The underspecified content of polysemic items produces interpretations in relation with characterised contextual indicators. This ternary set of schematic representations applies to the meaning organisation of French indefinite qui que ce soit ('any'). Universal positive readings, existential and opposition readings are generated by modalised predicate, a modalised proposition and syntactically adjoined functions. "Affective" contexts yield a negative polarity interpretation, the interpretation is generated through concessive reasoning, which explains how scalar values can be evoked by an item representing arbitrary selection. Such contextual reasoning and characterised contextual indicators are the two modes for the calculation of the contextual interpretation of polysemous items.

La politique linguistique et l'avenir du Francais au Mexique:etude du cas de l'universite de Veracruz

In a linguistic context where it seems the entire world is only interested in learning English, it is worth considering the idea of whether French still has a place in Mexico. In spite of the predominance of English, there is nevertheless a feeling that French remains alive in Mexico, and indeed in certain areas has retained its strength and appeal. This hypothesis was to put to the test by exploring the current linguistic environment prevalent in the state of Veracruz. An investigation in the form of questionnaires and interviews of all those connected to the teaching of French (including students, teachers and employees and directors of language schools) shows that the desire of the Mexican government of promoting English for everyone is not necessarily consistent with the desire and expectations of the general populace. This in turn suggest the need of adopting a policy that enables us not only to take into consideration what people seem to be telling us regarding the learning of foreign learning but also of what they are not telling us. If the teaching and learning of French as a foreign language remains strong in Veracruz, it is explained much more by the long and friendly relationship that people in the state have had with French people (and their culture) than it is by any instrumental needs of learning their language. This is seen in the fact that students here consistently describe their motivation for learning French from an emotional or affective standpoint rather than from professional one. It seems that the ties between the Mexican and French people remain solid. Another interesting characteristic of students of French in Veracruz is the positive attitude they seem to have regarding languages in general, which in turn enables them to take further advantage of the benefits made available from globalization. In reality, there exists no rivalry between French and English and therefore it is unnecessary to adopt measures that would address such struggle. It is however a matter of great urgency that authorities in the arenas of politics and academia take a closer look at the policies they design regarding the study of foreign languages in general, and that they consider, specifically, a wholly alternative to the one language model of teaching and learning of foreign language – in this case English-, a model that for all intents and purposes has failed. In the midst of a globalized world, and during this current period of increased linguistic activity, the aforementioned assertions serve not only to support my initial hypothesis, but also to help shake off the dust of some out-dated belief systems and lay down the framework for a new, better informed and well thought-out policy of foreign languages planning.

Brain connectivity in positive and negative syndrome schizophrenia

If, as is widely believed, schizophrenia is characterized by abnormalities of brain functional connectivity, then it seems reasonable to expect that different subtypes of schizophrenia could be discriminated in the same way. However, evidence for differences in functional connectivity between the subtypes of schizophrenia is largely lacking and, where it exists, it could be accounted for by clinical differences between the patients (e.g. medication) or by the limitations of the measures used. In this study, we measured EEG functional connectivity in unmedicated male patients diagnosed with either positive or negative syndrome schizophrenia and compared them with age and sex matched healthy controls. Using new methodology (Medkour et al., 2009) based on partial coherence, brain connectivity plots were constructed for positive and negative syndrome patients and controls. Reliable differences in the pattern of functional connectivity were found with both syndromes showing not only an absence of some of the connections that were seen in controls but also the presence of connections that the controls did not show. Comparing connectivity graphs using the Hamming distance, the negative-syndrome patients were found to be more distant from the controls than were the positive syndrome patients. Bootstrap distributions of these distances were created which showed a significant difference in the mean distances that was consistent with the observation that negative-syndrome diagnosis is associated with a more severe form of schizophrenia. We conclude that schizophrenia is characterized by widespread changes in functional connectivity with negative syndrome patients showing a more extreme pattern of abnormality than positive syndrome patients.
