Las alternativas de cambio de foco

En este artículo se analiza un grupo de alternancias de diátesis que denotan la misma oposición de significado: el cambio de foco de los participantes en el evento. El estudio se ha llevado a cabo a partir de un estudio de 1.000 verbos del castellano, el inglés y el catalán. Nuestro objetivo es poner de manifiesto la relación semántica existente entre diversas construcciones que tradicionalmente han sido estudiadas de manera independiente debido a sus diferencias formales pero que expresan una misma oposición semántica. La elección de una u otra alternancia corresponde a diferentes finalidades comunicativas.

O latim, uma língua morta?: uma metáfora em análise: o olhar da lingüística aplicada e suas implicações para o ensino

The focus of this research is the teaching of the Latin language. Due to the fact that its teaching has been facing a growing crisis in the last four decades, which currently persists, we ponder about external and internal causes of its decline, aiming at pointing out an alternative that enable us to find a way out of this situation. So, our research questions mainly concern how the teaching of Latin is viewed amongst the academic society, also investigating if it has kept up with the development of the scientific reflection about human language and the new approaches on language teaching. Furthermore, we analyse the contribution that the study of Latin can provide to the academic formation of language teachers and try to identify the areas of knowledge that can contribute to a reshaping of its teaching. Based on these guidelines, we have established as the goals of this research: 1) to reflect about the current situation of the teaching of Latin and the causes of its decline; 2) to determine its social representation among teachers and students of the Language Courses, as a way of defining the role it fulfills in the academic formation of teachers; 3) to accomplish an exploratory study of some handbooks that show alternative proposals on how to teach Latin, in order to detect their adequacy to current times and to the goals of the academic study of languages; 4) to offer an alternative proposal on how to teach Latin that takes into account the principles of Applied Linguistics, considering the socio-historical and cultural aspects of the language, enabling it to meet the requirements set by modern times. This research is divided into two parts. The first part presents the theoretical framework. We map the studies about Latin teaching inside and outside Brazil and argue against the concept of Latin being a dead language, presenting arguments set on changing this view. Then we describe and comment the notions of literacy, genre and culture, which helped us understand the reasons for the decline of the teaching of Latin and to point out suitable ways to overcome the crisis. The second part is dedicated to reflecting on the literacy practices in Latin teaching. We began by examining the answers to the questionnaires given to students and teachers about the view of Latin in the Language Courses; then we reflect on the teaching-learning of Latin as an academic literacy practice followed by an analysis of the didactic material used in teaching Latin. Finally, we suggest an approach of the familiar letter genre in ancient Rome as a means of teaching Latin in a contextualized way

La competencia lingüística en el uso de los grupos nominales en inglés académico y profesional y su didáctica: estudio empírico

Esta tesis doctoral consiste en un estudio empírico de la competencia lingüística del alumnado de la Escuela Técnica Superior de Ingenieros Industriales (ETSII), de la Universidad Politécnica de Madrid (UPM) en el uso de los grupos nominales (GN) en inglés profesional y académico (IPA). Mediante el análisis estadístico de los datos de las pruebas de nivel de inglés general y de conocimiento de los rasgos lingüísticos diferenciadores del IPA, se ha buscado constatar que los GN, tan presentes en los textos ingleses de carácter científico-técnico, son uno de los rasgos IPA que más dificultad presenta para el alumnado de ingeniería de habla española, cuya enseñanza es necesario abordar de forma diferenciada para que se puedan usar correctamente. El trabajo comienza presentando las características lingüísticas generales del IPA, entre las que destaca la frecuente presencia de los GN en las comunicaciones de carácter científico y técnico. Comprueba la hipótesis de que la comprensión y el uso de los GN es el rasgo lingüístico que ofrece mayor dificultad para esta población. Se detiene en explicar las propiedades de los GN en inglés y de las palabras que lo forman; es decir, muestra clases de palabras, regularidades y excepciones que están presentes en los textos científico-técnicos. También expone y razona el comportamiento de las distintas categorías gramaticales que pueden figurar como premodificadoras y se centra en ejemplos reales y datos objetivos, para llegar a conclusiones cuantitativas sobre el uso y la frecuencia de los GN en el discurso científico-técnico, así como en los diferentes grados de dificultad que dichas construcciones presentan al alumnado. El método de investigación seguido consiste en la recopilación y análisis estadístico de los datos procedentes de una muestra de población de alumnos de 5º curso de la ETSII de la UPM utilizando el análisis de la varianza ANOVA. Los datos se han tratado teniendo en cuenta el nivel general de inglés de cada alumno, según el Marco Común Europeo de Referencia para las Lenguas (MCERL), que oscila entre el nivel A2 y el C1, con una mayor frecuencia de B1 y B2. Las conclusiones se basan en el análisis de los datos empíricos obtenidos, que nos permiten deducir unos principios generales relevantes respecto al uso de los GN –simples y complejos- en el inglés para la ciencia y la tecnología (ICT) y al grado de dificultad que sus distintos tipos presentan al alumnado, con un grado de confianza superior al 95%. A partir de estos datos se ofrece un planteamiento didáctico que facilite la comprensión y elaboración de los distintos tipos de GN. La estructura general de la tesis se divide en seis capítulos. El capítulo 1 es una introducción en la que se presentan las razones que han motivado esta tesis, las hipótesis, los objetivos y la metodología de la misma. En el capítulo 2 se recogen los rasgos lingüísticos distintivos del ICT, incidiendo en la relación competencia comunicativa/competencia lingüística. En el capítulo 3 se analizan los GN profundizando en aspectos lingüísticos. El capítulo 4 se centra en el estudio empírico propiamente dicho y en el análisis estadístico de los datos. Del análisis se extraen las conclusiones objetivas sobre la dificultad que presentan los diferentes rasgos IPA analizados, con detenimiento en los GN simples y complejos. El capítulo 5 ofrece un planteamiento didáctico práctico sobre la enseñanza de los GN en el contexto del ICT, con una investigación sobre el terreno y el análisis estadístico de los resultados obtenidos antes y después de la aplicación didáctica. En el capítulo 6 se comentan los resultados obtenidos a lo largo del estudio, aportando las conclusiones, las limitaciones y las recomendaciones para futuros trabajos de investigación sobre el tema de la tesis. ABSTRACT This doctoral thesis consists of an empirical study of the linguistic competence of the Technical University of Madrid (UPM) industrial engineering students on the use of nominal groups (NG) in English for Academic and Professional Purposes (EAPP). In order to confirm that NG is the EAPP linguistic feature that presents the greatest difficulty to Spanish engineering students, a statistical analysis of the data obtained from the application of a general English test and the EAPP linguistic features tests -developed for this purpose- was carried out. Consequently, this linguistic feature needs to be specifically taught in order to be used correctly by Spanish engineering students. The study begins by presenting the general language characteristics of EAPP, among which the frequent presence of NG in scientific and technical writings stands out. It verifies the hypothesis that the understanding and use of NG in English is the most difficult linguistic feature for Spanish engineering students. It explains the features of English NG analyzing the words they are composed of by depicting the types of words, regularities and exceptions that are present in technical and scientific English. It also explains the behavior of the different grammar categories that act as pre-modifiers of the noun and focuses on real examples taken from authentic publications and quantitative data, to reach objective conclusions about the use and degree of difficulty of the NG for the students. The research methodology includes the gathering of data from the 5th year industrial engineering students´ tests and analyzing them by means of the ANOVA statistical application. The data have been treated in relation to the students’ Common European Framework of Reference for Languages (CEFRL) levels, which range from A2 to C1, although the majority lye between B1 and B2 levels. The conclusions are based on the results, which allow us to obtain relevant information about the understanding and use of NG –simple and complex- by the focus group, with a 95% confidence level. From these data, a methodological approach to NG teaching has been tested to help students to acquire such linguistic feature. The general structure of this thesis is divided into six chapters. The first is an introduction containing the reasons that have motivated this piece of research, the hypotheses, objectives and methodology employed. The second deals with the distinctive linguistic features of EST underlying the concepts of linguistic and communicative competence. Chapter three focuses on the grammar aspects of NG. Chapter four contains the empirical study and the statistical analysis of the data. Results allow us to reach objective conclusions about the degree of difficulty of the EAPP linguistic features studied, focusing on simple and complex NG. Chapter five discusses a methodological approach to the teaching of NG in an EST context, comparing students’ test results before and after the NG teaching application. Finally, chapter six discusses the findings obtained along the study, presenting the conclusions, limitations and recommendations for future research in this area.

Lingüística e arqueologia

This retrospective paper will shed light on the relations between Linguistics and Archaeology by drawing special attention to the history of Archaeology and the influence of Linguistic models for the development of archaeological interpretive frameworks. Reference will be made to culture history theoreticians, like Gordon Childe, to processual archaeologists influenced by Structuralism and to post-processual discourse analysis. The paper will conclude stressing the importance of Linguistics to archaeological thought.

A lingüística indígena no Brasil

This article presents a panorama of the area of the linguistics of the indigenous languages in Brazil within the discipline of Brazilian linguiistics as a whole. Special attention is given to those aspects related to its specific development. It is argued that in contrast to what is commonly supposed, the arrival of the Summer Institute of Linguistics (1959) not only was not the beginning of this area of study in the country, but it even contributed to the delay in its establishment. It was only after the return of Brazilian scholars educated abroad who were interested in the study of the national indigenous languages that a specialized branch of linguistics directed to the study of these languages began to take form. The present situation of the area and perspectives for future development are both explored.

Os caminhos da pragmática no Brasil

This paper traces the history of the study of pragmatics in Brazil. It is shown that Brazilian researches have, by and large, remained attentive to major developments in the field taking place elsewhere in the world. Of particular importance is the burgeoning tendency to focus attention on social issues affecting the day-to-day lives of ordinary people. More and more researchers are realizing the need to assume a critical role in relation to the theories they encounter in the literature.

The effects of the experimental infection from a focus of transmission of Schistosoma mansoni in a population of Biomphalaria tenagophila (D'Orbigny, 1835) in the region of "Vale do Ribeira de Iguape", Brazil

To observe the effects of the parasitic infection on the biology of B. tenagophila, field and laboratory populations of this mollusk from Itariri, in Vale do Ribeira, Brazil, were experimentally infected. Each mollusk received 10 miracidia of Schistosoma mansoni (SJ lineage) and was observed throughout the parasite's development. The biological variables were compared according to the criteria "group" and "infectious phase". The main damage caused by the parasitic infection manifested itself in reproduction, longevity and lesions on the shell of the mollusks in the patent phase. An infection rate of 58.8% was observed. Microanatomical study of the mollusk's digestive gland and ovotestis revealed the presence of evolving larval forms and cercariae. It was concluded that the effects of the parasitic infection on both populations were moderate, despite the low survival rate of the infected mollusks, the damage did not prevent either reproduction or the elimination of cercariae, which continued for a long time.

The finding of Lutzomyia almerioi and Lutzomyia longipalpis naturally infected by Leishmania spp. in a cutaneous and canine visceral leishmaniases focus in Serra da Bodoquena, Brazil

To identify natural infections by Leishmania spp. in insect vectors of cutaneous and visceral leishmaniasis, we performed field studies in natural and anthropic environments in the Guaicurus Settlement (Bodoquena Range) of the Bonito municipality, Mato Grosso do Sul state, Brazil. From October 2002 to October 2003, a total of 1395 sandfly females were captured with Shannon and light traps and dissected in search of flagellates. The sample is composed of a total of 13 species, with Lutzomyia almerioi (59.9%) and Lutzomyia longipalpis (31.4%) predominant. Infections by flagellates were directly observed in three of the dissected of Lu. almerioi females (0.36%). To increase the sensitivity of detection, DNA extracted from pools of the 1220 dissected females (Lu. almerioi 808, Lu. longipalpis 399 and Nyssomyia whitmani 13) was subjected to small subunit rRNA-based polymerase chain reactions (SSU-PCR). DNA from Leishmania (L.) infantum chagasi was detected in at least 0.37% of Lu. almerioi females and in 0.25% of Lu. longipalpis females. The DNA of the Leishmania (Viannia) sp. was detected in 0.12% of Lu. almerioi and in 0.70% of Lu. longipalpis. Leishmania (L.) amazonensis was found in 1.25% of Lu. longipalpis. Mixed infections of L. (Leishmania) sp. and L. (Viannia) sp. were found in 0.50% of Lu. longipalpis. When considering that each positive pool contained at least a single infected specimen, we found a 1.23% rate of Leishmania spp. infection among the total population of dissected female sand flies as determined by PCR. This is the first report of natural infection by L. (L.) infantum chagasi and L. (Viannia) sp. in Lu. almerioi. It is also the first report of infection by L. (Viannia) sp. in Lu. longipalpis. The observation that Lu. longipalpis and Lu. almerioi are naturally infected by agents of both cutaneous and visceral leishmaniases suggests that these two species play a role in the transmission (continua) (continuação) of these diseases within the study area. Furthermore, the finding that Lu. longipalpis has been naturally infected by L. (L.) amazonensis and L. (Viannia) sp., and Lu. almerioi by L. (L.) infantum chagasi and L. (Viannia), suggests their participation as permissive vectors

The effects of the experimental onfection from a focus of transmissopn of Schistosoma mansoni in a population of Biomphalaria tenagophila (D'Orbigny, 1835) in the region of "Vale do Ribeira de Iguape", Brazil

Com objetivo de observar os efeitos da infecção parasitária na biologia de B. tenagophila, foram realizadas infecções experimentais em populações de campo e laboratório, ambas procedentes de Itariri, Vale do Ribeira, Brasil. Cada molusco recebeu 10 miracídios de Schistosoma mansoni (linhagem SJ), sendo observado durante o desenvolvimento dos parasitos. As variáveis biológicas foram comparadas segundo os critérios "grupo" e "fase de infecção". Os principais danos decorrentes do parasitismo se manifestaram na reprodução, na longevidade e em lesões na concha dos moluscos na fase patente. Foi encontrada uma taxa de infecção de 58,8 por cento. O estudo microanatômico da glândula digestiva e do ovoteste do molusco revelou a presença de formas larvárias em evolução e cercárias. Concluiu-se que os efeitos da infecção parasitária, sobre as duas populações, foram moderados, uma vez que os danos não impediram a reprodução e a eliminação de cercárias que se manteve por um longo período, apesar da baixa sobrevivência dos moluscos parasitados

An external focus of attention results in greater swimming speed

We examined effects of attentional focus on swimming speed. Participants` task was to swim one length of a pool (16 m) using the front crawl stroke. In Experiment 1, intermediate swimmers were given attentional focus instructions related to the crawl arm stroke or the leg kick, respectively. Participants were instructed to focus on ""pulling your hands back"" or ""pushing the instep down"" (internal focus), or on ""pushing the water back/down"" (external focus), respectively. Swim times were significantly shorter with an external focus. In Experiment 2, a control condition was included. Times were significantly faster in the external focus compared with both the internal focus and control conditions. These findings have implications for enhancing performance in swimming.
