Fuzzy linguistic model for evaluating the risk of neonatal death

OBJECTIVE: To introduce a fuzzy linguistic model for evaluating the risk of neonatal death. METHODS: The study is based on the fuzziness of the variables newborn birth weight and gestational age at delivery. The inference used was Mamdani's method. Neonatologists were interviewed to estimate the risk of neonatal death under certain conditions and to allow comparing their opinions and the model values. RESULTS: The results were compared with experts' opinions and the Fuzzy model was able to capture the expert knowledge with a strong correlation (r=0.96). CONCLUSIONS: The linguistic model was able to estimate the risk of neonatal death when compared to experts' performance.

Children's metalinguistic activity in the construction of linguistic existence

In this paper we examine the construction of first entities in narratives produced by children of 5, 7, 10 years and adults1 . The study demonstrates that when children reformulate they try to construct entities detached from the situation of enunciation, which means that they construct a detached or a translated plane and they construct linguistic existence of entities. Entities must first be introduced into the enunciative space and then comments will be made in subsequent utterances. Constructing existence supposes extraction. This consists of “singling out an occurrence, that is, isolating and drawing its spatiotemporal boundaries” (Culioli, 1990, p. 182) . Once the occurrence of the notion is constructed (which means it has become a separate occurrence with situational properties), children can predicate about it. However, there are children who do not construct the linguistic existence of entities. I hypothesize that the mode of task presentation influences the success of constructing linguistic existence. Sharing the investigator’s knowledge about the stimulus images, children do not ascribe an existential status to the occurrence of the notional domain.

Fuzzy linguistic controllers applied to decouple control loop effects

A fuzzy linguistic controller has been developed and implemented with the aim to cope with interactions between control loops due to coupling effects. To access the performance of the proposed approach several experiments have also been conducted using the classical PID controllers in the control loops. A mixing process has been used as test bed of all controllers experimented and the corresponding dynamic model has been derived. The successful results achieved with the fuzzy linguistic controllers suggests that they can be an alternative to classical controllers when in the presence of process plants where automatic control as to cope with coupling effects between control loops. © 2014 IEEE.

Ethno-pragmatique et prosodie. Présentation d'une hypothèse de recherche pluridisciplinaire dans le domaine des sciences du langage et de la culture

L'hypothèse de recherche que nous souhaitons vous présenter ici a pour objet l&s fonctions pragmatiques de Ia prosodie. L'ensemble de notre Projet de Recherche s'organise en effet autour d'une seule (mais fondamentale) hypothèse de travail: c'est dans et par Ia prosodie que pour Vessentiel le langage contribue activement à Ia construction du lien social. La formulation de cette hypothèse resulte des travaux que nous avons menés dans le champ de FAnthropologie des rites, étudiés dans une perspective sémiologique (au sens large), visant à mieux saisir dans quelle mesure et selon quelles modalités, dans et par le rite, Vordre du signe est signe de 1'ordreK Le rite constitue un système complexe de comrpunication symbolique qui contribue en effet activement à definir sur le plan sémantique et à structurer sur le plan dramaturgique les situations d'interaction sociale.

Markets and linguistic diversity

The choice of language is a crucial decision for firms competing in cultural goods and media markets with a bilingual or multilingual consumer base. To the extent that multilingual consumers have preferences over the intrinsic characteristics (content) as well as over the language of the product, we can examine the efficiency of market outcomes regarding linguistic diversity. In this paper, I extend the spokes model and introduce language as an additional dimension of product differentiation. I show that: (i) if firms supply their product in a single language (the adoption model) then the degree of linguistic diversity is inefficiently low, and (ii) if some firms supply more than one linguistic version (the translation model) then in principle the market outcome may exhibit insufficient or excessive linguistic diversity. However, excessive diversity is associated to markets where the fraction of products in the minority language is disproportionately high with respect to the relative size of the linguistic minority.

Linguistic and maternal genetic diversity are not correlated in native mexicans

Mesoamerica, defined as the broad linguistic and cultural area from middle southern Mexico to Costa Rica, might have played a pivotal role during the colonization of theAmerican continent. It has been suggested that the Mesoamerican isthmus could have played an important role in severely restricting prehistorically gene flow between North and SouthAmerica. Although the Native American component has been already described in admixedMexican populations, few studies have been carried out in native Mexican populations. In thisstudy we present mitochondrial DNA (mtDNA) sequence data for the first hypervariable region (HVR-I) in 477 unrelated individuals belonging to eleven different native populations from Mexico. Almost all the Native Mexican mtDNAs could be classified into the four pan-Amerindian haplogroups (A2, B2, C1 and D1); only three of them could be allocated to the rare Native American lineage D4h3. Their haplogroup phylogenies are clearly star-like, as expected from relatively young populations that have experienced diverse episodes of genetic drift (e.g. extensive isolation, genetic drift and founder effects) and posterior population expansions. In agreement with this observation is the fact that Native Mexican populations show a high degree of heterogeneity in their patterns of haplogroup frequencies. HaplogroupX2a was absent in our samples, supporting previous observations where this clade was only detected in the American northernmost areas. The search for identical sequences in the American continent shows that, although Native Mexican populations seem to show a closer relationship to North American populations, they cannot be related to a single geographical region within the continent. Finally, we did not find significant population structure on the maternal lineages when considering the four main and distinct linguistic groups represented in our Mexican samples (Oto-Manguean, Uto-Aztecan, Tarascan, and Mayan), suggesting that genetic divergence predates linguistic diversification in Mexico.
