A syntactic-semantic analysis of English (non)-dativizable constructions in the production of a set of 2L1 English/Spanish simultaneous bilingual twins

This paper analyzes the syntactico-semantic factors which trigger Dative shift in English dativizable verbs, i.e. those verbs that allow alternation between double object and prepositional complement constructions. It also focuses on non-dativizable verbs that restrict their subcategorization framework to either double object or prepositional complement constructions. This syntactico-semantic relation between dativizable and nondativizable structures is addressed in acquisition by examining the incidence for the two verb types in a set of English/Spanish 2L1 bilingual twins. Our results show that the syntactic and semantic features that dativizable and non-dativizables present go hand in hand with the age of first occurrence and the language development of the participants. Hence, dativizable to-dative double object constructions (DOC) are the utterances produced the earliest at the age of 2, as opposed to dativizable to/for-datives and non-dativizable constructions, which begin to emerge at around the age of 3. Finally, our results also suggest that the high adult input frequency explains the twins' early production of dativizable structures and that, in the same way, the children's low exposure to non-dativizable utterances correlates with the later occurrence in the twins' spontaneous production.peer-reviewe

Study of conidia production and transmission of \u3cem\u3eBeauverza bassiana\u3c/em\u3e (balsamo) vuill. in Colorado potato beetle (\u3cem\u3eleptinotarsa decemlineata\u3c/em\u3e)

This work is an investigation of:( 1) mortality of the Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), under different modes of exposure to the pathogen Beauveria bassiana (Bals.) Vuill., (2) host and environmental factors affecting sporulation, production, and viability of B. bassiana conidia from infected cadavers of CPB larvae, and (3) transmission of the disease in CPB populations. The research leads to an improved understanding of the process of transmission of B. bassiana in CPB populations. This may enhance its use as a biological control agent for this pest insect. The highest rate of mortality of CPB larvae (77 percent) was achieved through direct spray of the insects with conidial suspensions of B. bassiana together with exposure to inoculated foliage. Direct spraying alone resulted in 76 percent mortality and exposure to inoculated foliage resulted in 34 percent. B. bassiana killed larvae sporulated within 2 days after death at 100 percent relative humidity and 25°C, and produced 1.75 x l04 to 8.7 x 108 conidid/insect. Cadaver size had the largest impact on the amount of conidia produced. Larvae treated as third and fourth instars produce significantly lower densities of conidia than larvae treated as first and seconds instars. Lower dosages of B. bassiana increased conidia production. Cadavers did not produce conidia at humidity levels lower than 95 percent. Exposure to intermediate levels of humidity resulted in a longer time to sporulation when at a later date the cadaver were transferred to optimal conditions for sporulation. Thus lower relative humidities are detrimental to the fungus. An optimum range of temperature for maximum production of conidia was observed to be between 15 and 30°C. Cadavers exposed to soil produced on average more conidia than cadavers incubated without soil for the same period of time. In the field, the most favorable environmental conditions for sporulation, production and viability of B. bassiana conidia occurred under a potato canopy. High relative humidity (\u3e95%) and soil moisture benefit sporulation and conidia production. Cadavers can persist in the field for more than 30 days and viability of conidia decreased over time but recovered after a rain event. Transmission of the disease in the potato canopy was too low to detect. Transmission was more likely to occur at the soil level where pre-pupae may encounter fallen sporulated cadavers while searching for a site to burrow for pupation

Social policies and society projects: crises, neo-liberalism and “neo-developmentalist” reconfiguration in Argentina in the 21st century

O presente artigo tem como foco central a reconfiguração da matriz de desenvolvimento vigente na Argentina, como resultado do aprofundamento da crise e dos conflitos sociais a partir de 2001-02. Identifica a presença de inflexões e continuidades neste momento de recomposição hegemônica, ao qual alguns autores denominam de ?fase pós-neoliberal neodesenvolvimentista?, fruto das correlações de forças resultantes no movimento geral da sociedade. Para tanto, aborda, em primeiro lugar, a reação neoliberal no marco da crise capitalista e a configuração da lógica de acumulação sob um padrão flexível. Em segundo lugar, analisa o contexto de crise do início do século XXI, destacando as inflexões e continuidades com o neoliberalismo e caracterizando o comportamento dos principais indicadores socioeconômicos. Em terceiro lugar, discute as reações ao neoliberalismo e a recomposição neodesenvolvimentista observadas na Argentina assim como em algumas experiências nacionais na região latino-americana, identificando continuidades e rupturas. Por último, tomando como referência este contexto, analisa a orientação das políticas sociais após a crise de 2001, pondo em discussão a ação estatal e suas políticas com os projetos de sociedade que se encontram em disputa na Argentina na atualidade.This present article has as its main focus the reconfiguration of the development matrix acting in Argentina, as a result of the deepening crisis and the social conflicts from 2001-02. Identifies the presence of inflexions and continuities in this moment of hegemonic recomposition, which some authors call of “post neo-liberal neo-developmentalist phase”, fruit of the correlations of forces resulting in the general movement of the society. Therefore, addresses, in first place, the neo-liberal reaction in the mark of the capitalist crisis and the logic configuration of the accumulation in a flexible standard. In second place it analyzes the context of crisis from the beginning of the 21st century, highlighting the inflexions and continuities with the neo-liberalism and characterizing the behavior of the main socioeconomic indicators. In third place , discusses the reactions to neo-liberalism and the neo-developmentalist recomposition observed in Argentina as well in some national experiences in the latin american region, identifying continuities and ruptures. For last , taking as reference this context, it analyzes the orientation of the social policies after the 2001 crisis, putting in discussion the state action and its politics with the projects of society that are in dispute in Argentina nowadays.Fil: Fernandez Soto, Silvia.

Influence of the notch-sharpening technique on styrene-acrylonitrile fracture behavior

The Centre Catala del Plastic and Universidad Rey Juan Carlos laboratories joined forces to investigate the effect of the notch-sharpening technique on the fracture parameters of styrene-acrylonitrile. Contact notch-sharpening techniques, such as razor tapping, razor sliding, and razor broaching, and a noncontact procedure, femtolaser, were analyzed. The fracture values of the samples with notches sharpened via contact techniques were divided into two groups: one with pop-in and the other with no pop-in in the load-displacement records; this resulted in the lowest and highest fracture toughnesses, respectively. The fracture parameters of the specimens with notches sharpened via a femtolaser were between those of the samples with notches sharpened via contact procedures in which pop-in occurred and those in which it did not. To explain these results, the crack front of the nontested specimens after sharpening was investigated in depth, we identified the type of damage and measured its size and the crack tip radii. The morphology of the crack front was related to the fractographic study.Postprint (author's final draft

The development of capitalism and the new configuration of social protection: the Universal allocation per child in Argentina

En este trabajo señalamos el contexto político, económico y social en que surge y se implementa la Asignación Universal por Hijo en Argentina como un programa de “Transferencias Monetarias Condicionadas” aprobado a fines del año 2009. Caracterizamos este programa a partir de un conjunto de dimensiones de análisis, desde una perspectiva amplia y compleja sobre la política social, e identificamos problemas en relación a la orientación y sentido ético político que persigue. En relación a estos interrogantes colocamos algunas tensiones centrales que hacen al desarrollo del capitalismo y a la implementación de políticas: la relación de las condiciones y formas de organización del trabajo y las desigualdades contemporáneas con las formas de protección social; el papel de las condicionalidades y las tensiones con perspectivas universalistas. De este modo damos cuenta de la configuración de un nuevo sistema de protección social acorde con las transformaciones del capitalismo contemporáneo.In this paper we pointed out the economic, political and social context that arises and implements the Universal allocation per child in Argentina as a program of "Conditional Cash Transfers" adopted at the end of the year 2009. We characterize this program from a set of dimensions of analysis, from a broad perspective and complex on social policy, and identify problems in relation to the orientation and sense of ethics that aim. In relation to these questions we put some tensions that make central to the development of capitalism and to the implementation of policies: the relationship of the conditions and forms of work organization and inequalities with contemporary forms of social protection; the role of the conditionalities and tensions with universalist perspective. In this way do we account for the configuration of a new system of social protection in line with the contemporary transformations of capitalism.Fil: Fernandez Soto, Silvia.
