The expressibility of modality in representational complement clauses in Brazilian Portuguese

This paper deals with the (im)possibility of expressing a variety of modal categories within the context of the layering approach to complementation in Functional Discourse Grammar (FDG).Our hypothesis is that modal expressions in complement clauses only pertain to operator or modifier classes of the highest layer relevant for that type of embedded construction and for all lower levels. In order to test this hypothesis, occurrences of complement clauses in two databases of spoken Brazilian Portuguese are analyzed. The investigation of this hypothesis is restricted to representational complement clauses.

Passives without actives: evidence from verbless complement clauses in Spanish

This paper proposes a constructionist analysis à la Goldberg (1995, 2003, 2006) of passive verbless configurations in Spanish lacking a felicitous active counterpart.Under the paradigmatic – rather than syntagmatic – view of passives invoked in this paper, configurations of the type in (1) above, attested with a number of verba cogitandi et dicendi, are handled as instances of the Impersonal Subjective-Transitive construction, whose general skeletal meaning is X (NP1) attributed Y (XPCOMP) by Z (NP2) in a direct, categorical way. Moreover, the analysis proposed here also provides a satisfactory account of the distribution of grammatical subjects and the XPCOMPs, while also capturing the commonalities with “regular” passives (i.e. those with a felicitous active counterpart). In addition, Spanish passive verbless complement configurations with se dice (‘is said’) are shown to illustrate a three-point continuum consisting of (i) non-grammaticalized configurations with an active counterpart, (ii) non-grammaticalized configurations without an active counterpart, and (iii) grammaticalized configurations without an active counterpart. From a synchronic point of view, the structural and semantico-pragmatic properties exhibited by the lower-level lo que se dice XPFOCUS construction, involving a focusing/emphasizer subjunct function (e.g. verdaderamente ‘really’) as well as a reformulatory connective use (e.g. o sea ‘that is’, en otras palabras ‘in other words’) appear to point to an early process of grammaticalization, exhibiting decategorialization as well as generalization of meaning in conjunction with a prominent increase in pragmatic function and subjectification (cf. Traugott 1988, 1995a, 1995b, 2003).

Interface vulnerability and knowledge of the subjunctive/indicative distinction with negated epistemic predicates in L2 Spanish.

Much recent research in SLA is guided by the hypothesis of L2 interface vulnerability (see Sorace 2005). This study contributes to this general project by examining the acquisition of two classes of subjunctive complement clauses in L2 Spanish: subjunctive complements of volitional predicates (purely syntactic) and subjunctive vs. indicative complements with negated epistemic matrix predicates, where the mood distinction is discourse dependent (thus involving the syntax-discourse interface). We provide an analysis of the volitional subjunctive in English and Spanish, suggesting that English learners of L2 Spanish need to access the functional projection Mood P and an uninterpretable modal feature on the Force head available to them from their formal English register grammar, and simultaneously must unacquire the structure of English for-to clauses. For negated epistemic predicates, our analysis maintains that they need to revalue the modal feature on the Force head from uninterpretable to interpretable, within the L2 grammar.With others (e.g. Borgonovo & Prévost 2003; Borgonovo, Bruhn de Garavito & Prévost 2005) and in line with Sorace's (2000, 2003, 2005) notion of interface vulnerability, we maintain that the latter case is more difficult for L2 learners, which is borne out in the data we present. However, the data also show that the indicative/subjunctive distinction with negated epistemics can be acquired by advanced stages of acquisition, questioning the notion of obligatory residual optionality for all properties which require the integration of syntactic and discourse information.

Alternância no uso dos modos indicativo e subjuntivo em orações subordinadas substantivas: uma comparação entre o português do Brasil e o francês do Canadá

The purpose of this work is to analyze the use of the indicative mood, instead of the subjunctive prescribed by the normative grammar, in complement clauses introduced by the conjunction que in Brazilian Portuguese. Contexts of use of the subjunctive according to grammatical prescription, and contexts of fluctuation on the use of that verbal mood were analyzed, in an attempt to investigate what interferes on the choice of the mood by the user of the language. This study is based on North-American Functional Linguistics theoretical perspective, oriented to analyzing language in use, in the light of the principles of grammaticalization and markedness. The results obtained support that the contexts that favor the indicative over the subjunctive are those composed by a complement clause functioning as a direct object the unmarked clause of all complement clauses and by a verb on the main sentence that belongs to the semantic field of low certainty, corresponding to the epistemic sub-mode the unmarked category of the deontic sub-mode. The results indicate that pragmatics and semantics factors influence the language user on the choice of the verbal mood. This research also presents comparative data on the use of the indicative mood in place of the subjunctive in Brazilian Portuguese and Canadian French, aiming to providing suggestions on language teaching

História de uma completiva: origem e desenvolvimento do complemento oracional introduzido por se do português

O propósito deste trabalho é investigar o percurso histórico da oração completiva iniciada pela conjunção se do português, que também introduz, nessa e em outras línguas românicas, uma oração adverbial condicional. Com base em registros de filólogos e romanistas, demonstra-se que a similaridade existente entre essas orações é resultado de gramaticalização da oração condicional que, no latim, passou a funcionar como oração completiva, em razão da extinção das partículas interrogativas que passaram a ser substituídas pela conjunção condicional latina si. Como oração completiva, a oração com se submete-se à gramaticalização, integrando-se à oração matriz de um modo que, conforme proposta de Hopper e Traugott (1993) e de Lehmann (1988), é próprio a construções completivas. A forma que tem essa oração de se gramaticalizar, incorporando-se à oração matriz, é, entretanto, diferente do que é previsto ocorrer a uma completiva introduzida por que, uma diferença que se deve, sobretudo, ao significado hipotético que a completiva com se preserva de sua fonte histórica. Demonstra-se, por fim, que, do português arcaico ao português contemporâneo, a gramaticalização do complemento oracional introduzido por se não se configura em mudança diacrônica, já que essa gramaticalização é atestada desde períodos mais remotos, em textos do século XIV.

Percurso diacrônico de completivas introduzidas por 'como' no português

As a more extensive issue, this paper deals with the polysemy attested in all Romance languages between interrogative pronouns and subordination markers in complex sentences. It investigates, specifically, the behavior of objective complement clauses introduced by “como” (“how”) in constructions in which they occur as equivalent to the meaning of prototypical declarative complement clause introduced by the conjunction “que” (“that”). It analyzes complement clauses introduced by “como” and “que” occurring in representative Portuguese texts from the thirteenth to the twentieth centuries. The results of the comparative analysis between the two forms of clausal complement show that in archaic Portuguese “como” was used primarily to introduce complement clauses of factive verbs. When the complement clause is introduced by “como”, the content that is presupposed as true due to the meaning of matrix verb has reinforced this factuality. In the passage from the archaic to the modern period, there was a drastic decrease in the frequency of occurrences of complement clauses with “como”, which are replaced by the form of completive introduced by the conjunction “que” in the context of factual constructions. In contemporary Portuguese, this replacement is fully established. Complement clauses with “como” remain rare and limited to specific contexts in which “como” maintains its reinforcement function of factual meaning.

Por uma abordagem funcionalista da complementação oracional

The main goal of this paper is to demonstrate the relevance of adopting a functionalist model which integrates aspects of both the main and completive clause to describe the phenomenon of clausal complementation. It is adopted the Functional Discourse Grammar theoretical framework which, unlike most approaches to the theme, focusing only on properties of the main clause, allows the analysis to combine functional aspects of both the main and the complement clauses. As a result of the discussions, the study highlights the importance of integrated analysis like this one for a broader comprehension about the formfunction relations in Portuguese complement constructions.

L'italiano neostandard nella lingua a scuola: il caso dell'alternanza fra indicativo e congiuntivo.

Il lavoro descritto in questo elaborato indaga la presenza dei tratti dell’italiano neostandard in un corpus di produzioni scolastiche scritte, con particolare attenzione all’uso di indicativo e congiuntivo nelle frasi completive. In particolare, delle tendenze di ristandardizzazione selezionate si osservano gli usi linguistici di alunni/e, le correzioni imposte dai/dalle docenti e le indicazioni delle grammatiche per la scuola; questa ricognizione permette di tracciare un quadro generale degli atteggiamenti della scuola nei confronti dei tratti del neostandard. La seconda parte dell’elaborato è dedicata a un’analisi dell’alternanza modale nelle subordinate completive; in primo luogo, si espone una revisione della letteratura sulla complementazione, sulla modalità e sul congiuntivo in italiano, con un focus particolare sulla sua recessione; in seguito, si procede all’analisi del fenomeno sulla base dei dati appositamente raccolti nelle scuole che hanno partecipato all'indagine. In secondo luogo, l’accettabilità dell’indicativo pro congiuntivo in testi scritti a scuola viene ulteriormente indagata tramite la somministrazione di un compito di correzione ai/alle docenti. L’ultima parte dell’elaborato accoglie un’analisi approfondita delle grammatiche per la scuola, la cui trattazione del congiuntivo è messa in relazione con le osservazioni della letteratura specialistica; ciò permette di completare il quadro riguardo agli atteggiamenti della scuola e di proporre riflessioni di natura glottodidattica.

Protein-energy malnutrition alters the C3 complement factor in response to lipopolysaccharide in a murine model

A desnutrição proteico-energética modifica a resistência à infecção, modificando diversos processos fisiológicos, incluindo a hematopoiese e as funções imunológicas. Neste estudo, avaliamos as concentrações séricas do fator C3 e do Sistema Complemento total (CH50) em um modelo no qual camundongos submetidos à desnutrição proteico-energética são estimulados com lipopolissacarídeo (LPS), e avaliamos a celularidade periférica, medular e esplênica. Camundongos Swiss, machos, adultos, com dois meses de idade foram submetidos ao processo de desnutrição proteica com uma dieta contendo 4% de proteína em comparação aos animais controles com uma dieta contendo 20% de proteína. Quando os animais do grupo desnutrido alcançaram aproximadamente 20% de perda de peso, em relação ao inicial, foram inoculados endovenosamente com LPS. As células do sangue, da medula óssea e do baço foram quantificadas, bem como as concentrações circulantes de C3 e CH50 em animais estimulados com LPS. Os animais desnutridos apresentaram anemia e leucopenia, além de redução significativa da celularidade da medula óssea e do baço. Os animais desnutridos apresentaram menor taxa de sobrevivência, bem como das concentrações do fator C3 do complemento e do complemento total em relação aos animais controles. Estes resultados sugerem que animais desnutridos apresentam uma resposta deficiente aos LPS. A síntese menor do complemento pode ser em parte responsável pela imunodeficiência observada. Estes resultados conduzem-nos a inferir que a desnutrição proteico-energética interfere na ativação da resposta imune

Biomass Refinery as a Renewable Complement to the Petroleum Refinery

Biomass Refinery is a sequential of eleven thermochemical processes and one biological process with two initial basic treatments: prehydrolysis for lignocellulosics and low temperature conversion for biomass with medium-to-high content of lipids and proteins. The other ten processes are: effluent treatment plant, furfural plant, biodiesel plant, cellulignin dryer, calcination, fluidized bed boiler, authotermal reforming of cellulignin for syngas production, combined cycle of two-stroke low-speed engine or syngas turbine with fluidized bed boiler heat recovery, GTL technologies and ethanol from cellulose, prehydrolysate and syngas. Any kind of biomass such as wood, agricultural residues, municipal solid waste, seeds, cakes, sludges, excrements and used tires can be processed at the Biomass Refinery. Twelve basic products are generated such as cellulignin, animal feed, electric energy, fuels (ethanol, crude oil, biodiesel, char), petrochemical substitutes, some materials (ash, gypsum, fertilizers, silica, carbon black) and hydrogen. The technology is clean with recovery of energy and reuse of water, acid and effluents. Based on a holistic integration of various disciplines Biomass Refinery maximizes the simultaneous production of food, electric energy, liquid fuels and chemical products and some materials, achieving a competitive position with conventional and fossil fuel technologies, as well as payment capacity for biomass production. Biomass Refinery has a technical economical capability to complement the depletion of the conventional petroleum sources and to capture its GHGs resulting a biomass + petroleum ""green"" combination.

Genetic analysis of complement C1s deficiency associated with systemic lupus erythernatosus highlights alternative splicing of normal C1s gene

Deficiencies of complement proteins of the classical pathway are strongly associated with the development of autoimmune diseases. Deficiency of Clr has been observed to occur concomitantly with deficiency in Cls and 9 out of 15 reported cases presented systemic lupus erythernatosus (SLE). Here, we describe a family in which all four children are deficient in Cls but only two of them developed SLE. Hemolytic activity mediated by the alternative and the lectin pathways were normal, but classical pathway activation was absent in all children`s sera. Cls was undetectable, while in the parents` sera it was lower than in the normal controls. The levels of Clr observed in the siblings and parents sera were lower than in the control, while the concentrations of other complement proteins (C3, C4, MBL and MASP-2) were normal in all family members. Impairment of Cls synthesis was observed in the patients` fibroblasts when analyzed by confocal microscopy. We show that all four siblings are homozygous for a mutation at position 938 in exon 6 of the Cls cDNA that creates a premature stop codon. Our investigations led us to reveal the presence of previously uncharacterized splice variants of Cls mRNA transcripts in normal human cells. These variants are derived from the skipping of exon 3 and from the use of an alternative 3` splice site within intron I which increases the size of exon 2 by 87 nucleotides. (c) 2007 Elsevier Ltd.
