From possessive pronoun to emphatic determiner: 'so' in Mauritian Creole

This paper argues that at a particular stage in the genesis of Mauritian Creole (MC), the 3sg possessive pronoun 'so', inherited from the French 'son' was used as a definite determiner as well as a possessive pronoun. It was used when there was a need to single out a unique element in the discourse, or to introduce a new referent which was to become the focus of attention. 'So' was mostly used with genitive constructions, where a phonologically null determiner was equally grammatical. This paper argues that, in the early creole, genitive constructions licensed the determinative use of this pronoun. The use of 'so' with genitive constructions is no longer grammatical in modern MC, but this particle continues to be used as an emphatic determiner, where it now modifies both singular and plural NPs.

The emergence of the determiner system in Mauritian Creole: a syntax semantics mapping

This paper describes the emergence of new functional items in the Mauritian Creole noun phrase, following the collapse of the French determiner system when superstrate and substrate came into contact. The aim of the paper is to show how the new language strived to express the universal semantic contrasts of (in)definiteness and singular vs. plural. The process of grammaticalization of new functional items in the determiner system was accompanied by changes in the syntax from French to creole. An analysis within Chomsky’s Minimalist framework (1995, 2000, 2001) suggests that these changes were driven by the need to map semantic features onto the syntax.

Duplication and concerted evolution in a master sex determiner under balancing selection.

The transformer (tra) gene is a key regulator in the signalling hierarchy controlling all aspects of somatic sexual differentiation in Drosophila and other insects. Here, we show that six of the seven sequenced ants have two copies of tra. Surprisingly, the two paralogues are always more similar within species than among species. Comparative sequence analyses indicate that this pattern is owing to the ongoing concerted evolution after an ancestral duplication rather than independent duplications in each of the six species. In particular, there was strong support for inter-locus recombination between the paralogues of the ant Atta cephalotes. In the five species where the location of paralogues is known, they are adjacent to each other in four cases and separated by only few genes in the fifth case. Because there have been extensive genomic rearrangements in these lineages, this suggests selection acting to conserve their synteny. In three species, we also find a signature of positive selection in one of the paralogues. In three bee species where information is available, the tra gene is also duplicated, the copies are adjacent and in at least one species there was recombination between paralogues. These results suggest that concerted evolution plays an adaptive role in the evolution of this gene family.

Determiner spreading as DP-predication

Determiner Spreading (DS) occurs in adjectivally modified nominal phrases comprising more than one definite article, a phenomenon that has received considerable attention and has been extensively described in Greek. This paper discusses the syntactic properties of DS in detail and argues that DS structures are both arguments and predication configurations involving two DPs. This account successfully captures the word-order facts and the distinctive interpretation of DS, while also laying the groundwork towards unifying it with other structures linking two DPs in a predicative relation.

On the (un)-ambiguity of adjectival modification in Spanish determiner phrases: informing debates on the mental representations of L2 syntax.

This study contributes to a central debate within contemporary generative second language (L2) theorizing: the extent to which adult learners are (un)able to acquire new functional features that result in a L2 grammar that is mentally structured like the native target (see White, 2003). The adult acquisition of L2 nominal phi-features is explored, with focus on the syntactic and semantic reflexes in the related domain of adjective placement in two experimental groups: English-speaking intermediate (n = 21) and advanced (n = 24) learners of Spanish, as compared to a native-speaker control group (n = 15). Results show that, on some of the tasks, the intermediate L2 learners appear to have acquired the syntactic properties of the Spanish determiner phrase but, on other tasks, to show some delay with the semantic reflexes of prenominal and postnominal adjectives. Crucially, however, our data demonstrate full convergence by all advanced learners and thus provide evidence in contra the predictions of representational deficit accounts (e.g., Hawkins & Chan, 1997; Hawkins & Franceschina, 2004; Hawkins & Hattori, 2006).

Indefinite determiner introducing definite referent: a special use of 'yi 'one' + classifier' in Chinese

The indefinite determiner yi 'one'+ classifier' is the most approximate to an indefinite article, like the English a, in Chinese. It serves all the functions characteristic of representative stages of grammaticalization from a numeral to a generalized indefinite determiner as elaborated in the literature. It is established in this paper that the Chinese indefinite determiner has developed a special use with definite expressions, serving as a backgrounding device marking entities as of low thematic importance and unlikely to receive subsequent mentions in ensuing discourse. 'yi+ classifier' in the special use with definite expressions displays striking similarities in terms of semantic bleaching and phonological reduction with the same determiner at the advanced stage of grammaticalization characterized by uses with generics, nonspecifics and nonreferentials. An explanation is offered in terms of an implicational relation between nonreferentiality and low thematic importance which characterize the two uses of the indefinite determiner. While providing another piece of evidence in support of the claim that semantically nonreferentials and entities of low thematic importance tend to be encoded in terms of same linguistic devices in language, findings in this paper have shown how an indefinite determiner can undergo a higher degree of grammaticalization than has been reported in the literature-it expands its scope to mark not only indefinite but also definite expressions as semantically nonreferential and/or thematically unimportant.

What nominal phrases are all about: the atypical case of indefinite pronouns with a determiner

This paper presents novel data that challenge the traditional categorial understanding of the nominal phrase. The established use of an indefinite pronoun with a determiner in French (ce quelqu'un, du n'importe quoi, un je ne sais quoi) contravenes assumptions both about pronouns, which should not be embedded, and nominal phrases, which should be headed by a noun. Analysed here for the first time, the embedding of a pronoun under a determiner is shown to find its justification in the semantic import of the construction. The anaphoric role guaranteeing referential continuity is promoted by a strong determiner; weak determiners typically contribute to constructing a designative use of the pronoun when a more precise characterisation cannot or will not be provided. How this construction would be analysed in the Minimalist Programme is presented to suggest that the phrase satisfies semantic requirements, which resolves the paradoxes of its traditional definition

Exploring the relation between the qualitative and quantitative uses of the determiner some

This article attempts to repair the neglect of the qualitative uses of some and to suggest an explanation which could cover the full range of usage with this determiner - both quantitative and qualitative - showing how a single underlying meaning, modulated by contextual and pragmatic factors, can give rise to the wide variety of messages expressed by some in actual usage. Both the treatment of some as an existential quantifier and the scalar model which views some as evoking a less-than-expected quantity on a pragmatic scale are shown to be incapable of handling the qualitative uses of this determiner. An original analysis of some and the interaction of its meaning with the defining features of the qualitative uses is proposed, extending the discussion as well to the role of focus and the adverbial modifier quite. The crucial semantic feature of some for the explanation of its capacity to express qualitative readings is argued to be non-identification of a referent assumed to be particular. Under the appropriate conditions, this notion can give rise to qualitative denigration (implying it is not even worth the bother to identify the referent) or qualitative appreciation (implying the referent to be so outstanding that it defies identification). The explanation put forward is also shown to cover some's use as an approximator, thereby enhancing its plausibility even further. © Cambridge University Press 2012.

The predicate marker li in Mauritian Creole

There is a morpheme 'li' in Mauritian Creole (MC), which is homophonous with the 3sg pronoun, and which, in the early creole, occurs frequently between the subject and the predicate in affirmative, present tense clauses. I propose that that 'li' may have originated as a resumptive pronoun, co-referential with the subject, but following the grammaticalization of new determiner elements to mark the semantic contrasts of [±definite] and singular vs. plural, 'li' has now grammaticalized into a predicate marker. Its presence is sensitive to both the nature of the predicate, and to the definiteness and specificity features of the subject NP. My analysis is within the framework of Truth Conditional Semantics, where indefinite NPs are analyzed as variables that get introduced into the discourse, and must be bound by an operator to yield a closed proposition, with a truth value. Drawing on a comparison with a cognative morpheme 'i' in Seychellois Creole, I claim that its path to grammaticalization is linked to that of the specificity marking 'la'.

A conspiracy theory for clefts : the syntax and interpretation of cleft constructions

O objetivo final deste estudo é contribuir para a discussão sobre qual a medida em que conceitos semânticos e discursivos estão sintaticamente codificados. Mais especificamente, investiga-se se existe alguma correlação consistente entre alguns aspetos interpretativos e sintáticos de quatro construções clivadas do Português Europeu, e como se deve dar conta teoricamente destas potenciais correlações. As clivadas consideradas são as clivadas canónicas, as pseudoclivadas, as clivadas de é que e as clivadas de SER. Sintaticamente podemos distinguir dois tipos: clivadas bioracionais (canónicas e pseudoclivadas) e clivadas mono-oracionais (clivadas de é que e de SER). Todas as estruturas têm um constituinte clivado focalizado que pode constituir tanto um foco informacional como um foco contrastivo, e uma oração clivada que introduz uma pressuposição existencial. Adicionalmente, o constituinte clivado identifica exaustivamente uma posição vazia na oração clivada. Adota-se a semântica alternativa para o foco (Rooth 1985), segundo a qual o foco entoacional contribui uniformemente um conjunto de alternativas na Forma Lógica. Regras pragmáticas operando neste conjunto dão origem a duas implicaturas que podem ser suspensas: pressuposição existencial e exaustividade. Dado que as clivadas de é que e as de SER têm a mesma interpretação que orações não-clivadas, conclui-se que a sua estrutura sintática particular não contribui para estas propriedades interpretativas. Em contrapartida, as clivadas bioracionais, que são orações copulativas especificacionais, têm uma presuposição existencial e uma interpretação exaustiva que não pode ser suspensa, tal como as orações especificacionais não-clivadas. Argumenta-se que isto se deve ao facto de o constituinte clivado identificar uma variável introduzida por uma descrição definida. Demonstra-se que a oração clivada, uma relativa em posição de complemento de um determinador definido nas clivadas canónicas e uma relativa livre nas pseudoclivadas, tem a mesma denotação que um DP definido, e portanto tem uma pressuposição existencial inerente. A interpretação exaustiva deve-se à relação identificacional entre o constituinte clivado e a descrição definida. Além disso, defende-se que em Português Europeu um traço de foco não desencadeia movimento-A’ para um FocP especializado. Os constituintes focalizados movem-se antes por razões independentes do foco. Isto é confirmado pelo facto de apenas o constituinte clivado das clivadas de é que ter propriedades de movimento A’, os outros parecem estar in situ. Propõe-se que o constituinte clivado das clivadas de é que é um tópico com um traço de foco que se move para um TopP. Esta análise dá conta da existência de restrições discursivas semelhantes para tópicos não focalizados e para o constituinte clivado das clivadas de é que. O traço quantificacional de foco arrastado pela topicalização dá origem a efeitos de intervenção, causando a não-recursividade do foco na periferia esquerda e a sua incompatibilidade com movimento de outros constituintes com traços quantificacionais. A análise prediz as restrições de encaixe observadas para as clivadas de é que. Finalmente, desenvolve-se uma análise sintática das clivadas de SER que aproxima estas estruturas das estruturas com partículas de foco. Propõe-se que a cópula é um operador sensível ao foco que é merged juntamente com o constituinte clivado. As restrições distribucionais da cópula devem-se a requisitos selecionais de núcleos.

Contribuição para o conhecimento da intoxicação pelo veneno dos "escorpiões"

Nous avons travaillé à Bello Horizonte, Etat de Minas, avec le venin de 4 espèces de Scorpions: Tityus bahiensis (C. L. KOCK, 1836). Tityus serrulatus (LUTZ-MELLO, 1922). Tityus dorsomaculatus (LUTZ – MELLO, 1922). Bothriurus (espèce em étude), sur un total de 13.640 individus. Nous avons essayé et observe l’action du venin sur 97 espèces differentes d’êtres vivants – depuis les chlamydozoaires jusqu’à l’«Homo sapiens». Nous avons cherché à déterminer une unité toxique «plus précise, plus régulierè». Les étalons dits «unité vésicule», «unité morsure» sont inconstants et sans rigueur. Tout au plus, peuvent ils server à l’étude de l’action générale du venin, et cela meme, dans certains cas seulement. Nous avons employé la pesée pour determiner l’unité toxique. Ce qui est important pour qui étudie ces sujets ce n’est pás lê nombre de vésicules, mais bien la quantité de venin humide ou desséché qu’elles contiennent. La balance, pour notre travail, est um moyen indicateur de bien plus grande précision que la «vésicule» ou la «morsure». Nous sommes parvenus à prouver qu’il existe une relation constante entre le poid brut des vésicules et la quantité de venin humide ou desséché qu’elles contiennent dans leur intérieur. Donc em pesant les vésicules, nous pesons indirectement le venin. Peu nous importe qu’il y ait 10 ou 100 vésicules. Il nous importe seulement de savoir combien elles pèsent, et de déterminer par ce fait, la quantité proportionnelle de vain pur. La technique générale est la suivante: Nous pesons um certain nombre de vésicules. Nous triturons ensuite, dans um mortier stérilisé et nous emulsionnons, par l’addition consécutive d’eau distillée, stérilisée. Nous filtrons l’émulsion sur le papier filtre employé em chimie, préalablement taré et desséché dans une atmosphere de chlorure de calcium. Après le filtrage on sèche à nouveau les papiers filtre employés d'abord à l'étuve et ensuite dans la même atmosphère de chlorure de calcium. Nous pesons plusieurs fois et on obtient la moyenne de ces pesées. On soustrait de cette dernière pesée le taux des substances non venimeuses, glandulaires, également dissoutes et calculées à 23 du poids brut et celles retenues par les papiers,-on obtient ainsi la moyenne réelle du venin pur contenu dans les vésicules utilisèés. Une simple divisiôn suffit pour fixer la moyenne de chacune. Ces données ont été vérifiées par les expériences faites avec du venin pur, largement obtenu dans notre Laboratoire. Nous avons trouvé de la sorte pour une vésicule de Tityus serrulatus: 0,gr.000,386 de T. bahiensis: 0,gr.001.261.24 de venin pur ce qui donne. 7/15,96 pour la 1ère. 1/8,36 pour la 2ème du poids sec de chaque vésicule. Le poids sec, pour une moyenne obtenue de 1.000 vésicules, fut de 0,gr.008,236 pour Tityus bahiensis. Maximum 0,gr.011. Minimum 0,gr.004.4 pour chacun. Pour Tityus serrulatus, en 1.049 vésicules le poids fut de 0,gr.006,08. Maximum 0,gr.014.03. Minimum 0,gr.003,1 pour chacun. C'est pour cette raison que l'unité-vésicule est incertaine. 2 poules A et B.; l'une, A, pesant 2 K.030 gr. reçoit dans une veinè, une émulsion en sèrum physiologique à 8,50/%, stérilisé, de 19 vésicules totales de Tityus serrulatus, et présence de légers phénomènes toxiques. L'autre, B, pesant 2 K.320 gr. meurt avec tous les phénomènes classiques de l'empoisonnement, par l'injection endoveineuse del'émulsion de 16 vésicules totales de venin de Tityus serrulatus! Les premières 19 vésicules pesaient 0,gr.58; les 16 derniéres-84 milligrammes. Les premières contenaient 0,gr.003. 634 et les secondes 0,gr.005.263 de venin pur! La moyenne obtenue de 6346 scorpions, (entre T. bahiensis et T. serrulatus) nous a fourni pour chacun: 0,gr.000,131,53 de venin pur, par piqûre. Si l'on spécifie: Pour 5.197 T. bahiensis. La moyenne pour une piqûre est 0,gr.000.106.15. Pour 1.149 T. serrulatus, la moyenne pour une piqûre est.......0,gr.000.246.30. La quantité a varié, selon les individus, de 0,gr.000.035.71, à 0,gr.000.436.01 de venin pur, pour une piqûre. D'après ce qui vient d'étre dit, on peut voir combien la quantité de venin éjaculé varie, chaque fois, chez les scorpions. L'unité-piqûre ne peut done pas ètre utiliseé pour des expériences dèlicates. Le mieux est de se servir de venin pur, et c'est ce que nous avons fait pour les expériences minutieuses. Quand on n'en possède pas, on peut établir pour chaque série des expériences à tenter-la dose minima mortelle en poids (grammes et fractions) de vésicules. D'après les bases ici consignées, et avec une trés petite erreur, on peut calculer la quantité de venin pur de cette dóse. Ce calcul est d'ailleurs dispensable. On peut s'en rapporter simplement au poids sec des vésicules totales et dire que la D. m. m. est de tant de milligr. secs. Comme le venin se conserve mal dans les vésicules, il faut, dans ce procédé, doser la D. m. m. toutes les fois que l'on veut procéder á une sériê d'expériences. Le venin desséché rappelle, d'après le temps de conservations au Laboratoire, celui de Crotatus terrificus et celui des Lachesis (quand il est vieux). Il est retenu au passage en partie, par les bougies Berkfeld et Chamberland. La conservation en état de dessication est la meilleure. Ainsi gardé, à l'abri de la lumierè, aux approches de 0,gr., pendant 8 mois, il perd à peine 1,2 à 1,4 de sa valeur primitive. L'echauffement à 100 gr. trouble une dissolution de venin dans l'eau distilleé; sans atteindre toutefois son pouvoir toxique, quand on l'injecte par la voie intra-cérébrale. Nous avons fait l'experience par 11 voies diverses. Sur des animaux sensibles, nous n'avons pas obtenu de phénomènes toxiques, apparemment, par les voies suivantes: 1) buccale; 2) gastrique; 3) rectale; 4) chambre oculaire antérieure; 5) cornéenne; 6) trachéenne; 7) meningée {sur; intra; 8) simple contact, bien que direct, avec le systemè nerveux central. La gravité des phènomènes décroît suivant l'échelle ci-dessous: 1) intra-cérébrale...

Effects of Bilingualism on Multi-Word Production

It has been shown that bilinguals are disadvantaged on some language production tasks when compared to monolinguals. The present study investigated the effects of bilingualism on lexical retrieval in single and multi-word utterances. To this purpose, we tested three groups of 35 participants each (Spanish monolinguals, highly proficient Spanish-Catalan and Catalan-Spanish bilinguals) in two sets of picture naming experiments. In the first one, participants were asked to name black-and-white object drawings by single words. In the second one, participants had to name colored pictures with determiner adjectival noun phrases (NP) like “the red car”. In both sets of experiments, bilinguals were slower than monolinguals, even when naming in their dominant language. We also examined the articulatory durations of both single word and NP productions for this bilingual disadvantage. Furthermore, response onset times and durations of all groups in both experiments were affected by lexical variables of the picture names. These results are consistent with previous studies (Ivanova & Costa, 2008, Gollan et al., 2005) showing a bilingual disadvantage in single word production and extend these findings to multiword-utterances and response durations. They also support the claim that articulatory processes are influenced by lexical variables.
