Acquisition of inflected and uninflected infinitives in child L1 European Portuguese

This study investigates the child (L1) acquisition of inflected and uninflected infinitives in European Portuguese (EP). We test and contrast properties involving two interfaces, focusing on morpho-syntactic and syntax-semantics properties of inflected infinitives, in contrast with uninflected infinitives. We present experimental results from three monolingual EP child groups, between ages 6 and 12 (n=72), compared to EP adults (n=32). Results show that children as young as 6-7 have knowledge of the morpho-syntactic properties of inflected infinitives, although at first glance they show insufficient knowledge of their syntax-semantics interface properties (i.e. non-obligatory control properties), differently from older children, who show evidence of knowledge of both types of properties. We argue that, in general, morpho-syntactic and syntax-semantics interface distinctions are also accessible to 6-7 children, but children may not show the entire range of interpretations possible for adults.

Processing coordinate subject-verb agreement in L1 and L2 Greek

The present study examines the processing of subject-verb (SV) number agreement with coordinate subjects in pre-verbal and post-verbal positions in Greek. Greek is a language with morphological number marked on nominal and verbal elements. Coordinate SV agreement, however, is special in Greek as it is sensitive to the coordinate subject's position: when pre-verbal, the verb is marked for plural while when post-verbal the verb can be in the singular. We conducted two experiments, an acceptability judgment task with adult monolinguals as a pre-study (Experiment 1) and a self-paced reading task as the main study (Experiment 2) in order to obtain acceptance as well as processing data. Forty adult monolingual speakers of Greek participated in Experiment 1 and a hundred and forty one in Experiment 2. Seventy one children participated in Experiment 2: 30 Albanian-Greek sequential bilingual children and 41 Greek monolingual children aged 10–12 years. The adult data in Experiment 1 establish the difference in acceptability between singular VPs in SV and VS constructions reaffirming our hypothesis. Meanwhile, the adult data in Experiment 2 show that plural verbs accelerate processing regardless of subject position. The child online data show that sequential bilingual children have longer reading times (RTs) compared to the age-matched monolingual control group. However, both child groups follow a similar processing pattern in both pre-verbal and post-verbal constructions showing longer RTs immediately after a singular verb when the subject was pre-verbal indicating a grammaticality effect. In the post-verbal coordinate subject sentences, both child groups showed longer RTs on the first subject following the plural verb due to the temporary number mismatch between the verb and the first subject. This effect was resolved in monolingual children but was still present at the end of the sentence for bilingual children indicating difficulties to reanalyze and integrate information. Taken together, these findings demonstrate that (a) 10–12 year-old sequential bilingual children are sensitive to number agreement in SV coordinate constructions parsing sentences in the same way as monolingual children even though their vocabulary abilities are lower than that of age-matched monolingual peers and (b) bilinguals are slower in processing overall.

Synthesis of L1(0) Fe-Pd films by electrodeposition and thermal annealing

Fe-Pd alloy films have been prepared by electrochemical deposition from an alkaline electrolyte containing Fe sulfate, Pd chloride and 5-sulfosalicylic acid onto polycrystalline titanium substrates. The as-deposited films were nanocrystalline and magnetically soft (coercivity similar to 25 Oe). L1(0) Fe-Pd films with a (111) preferred orientation were obtained by post-deposition thermal annealing of films with composition about 37 at% Fe in an (Ar + 5% H-2) gas flow at 500 degrees C. Such films exhibit hard magnetic properties, with a coercivity up to 1880 Oe, and a slightly anisotropic magnetic response, with a larger in-plane remanence. Preliminary magnetic investigations support magnetization switching through pinning of domain walls. (c) 2008 Elsevier B.V. All rights reserved.

Perpendicularly self-oriented and shape-controlled L1(0)-FePt nanorods directly synthesized by a temperature-modulated process

The synthesis and self-assembly of tetragonal phase-containing L1(0)-Fe(55)Pt(45) nanorods with high coercive field is described. The experimental procedure resulted in a tetragonal/cubic phase ratio close to 1:1 for the as-synthesized nanoparticles. Using different surfactant/solvent proportions in the process allowed control of particle morphology from nanospheres to nanowires. Monodisperse nanorods with lengths of 60 +/- 5 nm and diameters of 2-3 nm were self-assembled in a perpendicular oriented array onto a substrate surface using hexadecylamine as organic spacer. Magnetic alignment and properties assigned, respectively, to the shape anisotropy and the tetragonal phase suggest that the self-assembled materials are a strong candidate to solve the problem of random magnetic alignment observed in FePt nanospheres leading to applications in ultrahigh magnetic recording (UHMR) systems capable of achieving a performance of the order of terabits/in(2).

La noción de lo esencial en la enseñanza de lenguas modernas según los profesores. : Entrevistas con cinco profesores sobre la norma "Todo lo esencial de la enseñanza debe realizarse en la lengua meta" de Gy11.

La tesina investiga cómo cinco profesores interpretan la norma de Gy11 que indica que todo lo esencial de la enseñanza de lenguas modernas debe realizarse en la lengua meta. Las entrevistas semiestructuradas indican que los profesores interpretan la norma de maneras parecidas, es decir, que los profesores deben usar la lengua meta lo máximo posible en la enseñanza. La mayoría de los profesores están de acuerdo con la norma, sin embargo, tienen varias críticas contra Skolverket y la formulación de la norma. Ninguno de los profesores ha cambiado su uso de la lengua meta en el aula debido a la norma.

L1 Use in the EFL-classroom : A Literature Review on Teachers’ Use of the L1 in the EFL-classroom on Upper Secondary Level

Even though English should mainly be used in the EFL-classroom according to the Swedish national curriculum, some recent scholars have argued that a judicious use of the students’ L1 by the teachers in some particular situations may benefit the learning environment there. From this context, this thesis examines what research says about in what particular situations the L1 is used by teachers in upper secondary EFL-classrooms as well as the teachers’ and the students’ attitudes towards this practice. The method used was a systematic literature review, where seven articles from all across the globe were analyzed, compared and synthesized. The results show that the L1 was mainly used by the teachers when managing discipline, when explaining grammar and when teaching vocabulary. However, the articles did not conclude how the L1 could be used strategically by the teachers. Concerning the teachers’ and students’ attitudes, the majority of these were positive towards L1 use by the teacher in the above mentioned situations. However, the teachers were not aware of how the L1 could be used by them in a judicious and a strategic way. Lastly, it can be concluded that more research is needed on how the L1 can be used more strategically by the teachers as well as on the students’ perspective on this.

Using Swedish in the EFL-classroom : An Interview Study on Swedish Upper Secondary Students’ Attitudes towards Teachers’ L1 use in the EFL-classroom

There is very little focus in previous research on first language (L1) use by teachers in the upper secondary English as a foreign language (EFL) classroom from the students’ perspective. In this context and from a Swedish perspective, this thesis examines what attitudes students in the Swedish upper secondary school have towards their teachers’ use of L1 (Swedish) in the EFL-classroom. The method used was qualitative semi-structured interviews, where nine students in total were interviewed. The collected data was then coded, thematized and categorized. The results show that the students mainly believed Swedish should be used when teaching vocabulary, when teaching grammar and for classroom management. They did not believe the L1 should be used by them in questions and answers and in general talk in the classroom. They also endorsed an overall judicious use of Swedish by their teachers and that their use of this language should be adjusted to the specific teaching group. Finally, it can be concluded that further research is needed on how the L1 can be used judiciously in particular situations and on what attitudes students of varying proficiency and age, as well as students who do not have Swedish as their L1 have towards teachers’ L1 use in the EFL-classroom.

Avaliação do erro das coordenadas de localização estereotáctica guiada por tomografia computadorizada do encéfalo

São analisados 106 pacientes submetidos a localização estereotáctica. Os procedimentos variaram de biópsias cerebrais, orientação de craniotomias, colocação de cateter em cavidade tumoral, drenagem de hematoma intracerebral e drenagem de abscesso cerebral. As orientações de craniotomias foram para MAVs, tumores e processos inflamatórios, em 21 pacientes. As biópsias cerebrais estereotácticas para diagnóstico anatomopatológico apresentaram um índice de positividade de 87,50 % com complicações em 1,20 %, em 82 casos. São analisadas estatisticamente as variáveis como: idade, sexo, procedimento realizado, diagnóstico anatomopatológico e volume das lesões. É discutida a imprecisão na aquisição e cálculo das coordenadas estereotácticas com a TC do encéfalo e verificada a precisão do método estereotomográfico com a utilização de um phanton. O maior erro das coordenadas foi de 6,8 mm.

Proposta de utilização do planejamento estratégico na preparação de um modelo geral de estrutura de mudança para implantação de um sistema da qualidade baseado na norma ISO série 9000

A competitividade do mercado tem levado empresas, pressionadas por concorrentes e com recursos limitados, a tomarem ações imediatas para garantir sua sobrevivência. Os escassos recursos materiais e humanos disponíveis necessitam ser investidos na operacionalização de estratégias bem planejadas que possam garantir a competitividade no curto, médio e longo prazos. Um erro no posicionamento estratégico pode comprometer de forma bastante significativa uma organização. Este trabalho apresenta o estudo de caso efetuado em uma empresa de componentes eletrônicos sobre a proposta de utilização do Planejamento Estratégico na preparação de um modelo geral de mudança de estrutura para Implantação de um Sistema da Qualidade baseado na Norma ISO Série 9000. Este estudo serve como alerta aos administradores quanto aos riscos e perdas a que podem estar se expondo quando alocam tempo, capital e pessoas, para somente obter o certificado ISO, sem enfatizar o aprendizado decorrente desta certificação. A implantação de um sistema da qualidade passa a ser visto como uma ferramenta e não só com um conjunto de normas que permitem obter um certificado. O estudo possibilitou a constatação, na prática, das várias fases que conduzem uma empresa a introduzir em suas atividades o Sistema da Qualidade.

A indeterminação de senior e o curriculo minimo de economia

Expõe-se um programa de pesquisa sobre a natureza incompleta do conhecimento científico, estendendo-o para análise do currículo mínimo de economia no Brasil, e a consequente formulação de propostas de mudança. Considerando os diferentes níveis de abstração na tricotomia ciência pura, aplicada e arte da ciência, observa-se que o currículo mínimo prescreve formação apropriada para a economia social ou aplicada. Conclui-se pela conveniência de mais dois anos, um para reforço da economia pura no ciclo básico, outro para a arte da economia no profissionalizante. Considera-se ainda uma especialização em economia pura, voltada apenas para ensino e pesquisa.
