  1. Effects of Noise Reduction on AM and FM Perception

    Ives, DT; Calcus, A; Kalluri, S; Strelcyk, O; Sheft, S; Lorenzi, C
    The goal of noise reduction (NR) algorithms in digital hearing aid devices is to reduce background noise whilst preserving as much of the original signal as possible. These algorithms may increase the signal-to-noise ratio (SNR) in an ideal case, but they generally fail to improve speech intelligibility. However, due to the complex nature of speech, it is difficult to disentangle the numerous low- and high-level effects of NR that may underlie the lack of speech perception benefits. The goal of this study was to better understand why NR algorithms do not improve speech intelligibility by investigating the effects of NR...

  2. Competencias del bioeticista en perspectiva ricoeuriana

    Álzate Mejía, Nicolás Alberto
    Abstract: The competences of the bioethicist in a ricoeurian perspective, the title of this article, is a completely novel result of a study of hermeneutic-analytical kind, which is entitled The contributions of ricoeurian hermeneutics to the epistemological statute of bioethics, which is still in gestation, in that the same Bioethics is a discipline that is only forty years old and continues to seek its epistemological foundation, which so far has been weaved based on the interdisciplinary contributions of philosophy, religion and the medical ethics science.The article presents a series of anthropological kind competencies identified as those responsible for clarifying issues...

  3. Configuraciones retórico-lingüísticas del resumen en artículos científicos de economía: contrastes en el interior de la disciplina

    Stagnaro, Daniela
    Over the last few decades, Linguistics has made a number of contributions to the understanding of academic-scientific discourse, in particular of the linguistic-rhetorical features of core genres in scientific communication. Among those genres, the scientific article has received greater attention because of its centrality in the research process. However, the literature has often approached each discipline discourse homogenously, without taking into account the branches or perspectives within each field of knowledge. In the light of a tradition of studies of languages for specific purposes, this paper aims at contributing to our knowledge of intra-disciplinary variation. Based on the assumption that there is a relationship of mutual determination between...

  4. Uso estratégico de representaciones pictóricas en un texto de ciencias con un detalle seductor en lectores con bajo conocimiento previo

    Saux, Gastón; Irrazabal, Natalia
    The Cognitive Theory of Multimedia Learning (Mayer, 2001, 2005) argues that processing joint linguistic and pictorial information results in an integrated mental representation of the message, and that this can both benefit and lessen reading performance, depending on the function of such additions. This study examined the effect of including pictorial representations in an expository text in Spanish that included a tangential but interesting biographical fact (seductive detail). One hundred and forty seven low prior-knowledge participants read the text with the seductive verbal detail in one of three versions: non-illustrated (Verbal Detail Only condition), with an image linked to the verbal seductive detail (Seductive Multimedia condition), or with a...

  5. The impact of a linguistic intervention on rhetorical inferential comprehension and metacognition in EFL academic reading: a quasi-experimental, mixed-methods study

    Perales Escudero, Moisés; Reyes Cruz, María del Rosario; Hernández Méndez, Edith
    The connections between metacognition and metalinguistic awareness are underresearched and poorly understood in the field of foreign language reading. This paper uses a linguistic intervention to investigate the connections between rhetorical inference making, linguistic awareness inspired in Systemic-Functional Linguistics (SFL), and forms of metacognition. An intervention inspired in SFL was designed and implemented using a quasi-experimental design. The target genres were the introduction of the empirical research article and the discussion article. The control group received traditional instruction focusing on background knowledge and vocabulary. Answers to a pre-/post-test were analyzed quantitatively; answers to a written, self-report questionnaire were analyzed qualitatively. The quantitative results show gains in inferential comprehension for...

  6. Hacia una normalización de la frecuencia de los corpus CREA y CORDE

    Molina Salinas, Claudio; Sierra, Gerardo
    El Corpus Diacrónico del Español (CORDE) y el Corpus de Referencia del Español Actual (CREA) integran uno de los bancos de datos documentales más grande del español y son usados por especialistas en el estudio de la lengua española. Este recurso presenta algunas limitaciones en términos de tamaño, unidad de muestra y representatividad, que condicionan sus resultados y, por tanto, las descripciones de cualquier fenómeno lingüístico estudiado. En el presente trabajo identificamos estas limitaciones y proponemos un método de normalización de frecuencias de documento, por medio del cálculo de medias móviles. Esto permite una interpretación más realista de la lengua española, a través de los datos del corpus,...

  7. Indicadores de cambio temático en el discurso parlamentario: análisis de un discurso de Rodríguez Zapatero [2011]

    Cortés Rodríguez, Luis María; Hidalgo Downing, Raquel
    The notion of topic has received much attention in linguistics and has been studied from different perspectives, although the concept has not always been applied to the analysis of texts. In this article, we analyze a political speech delivered at the Spanish Parliament and describe the strategies used by the speaker to signal topic shift, and in particular, topic introduction. In the analysis of the data we have identified vocatives, discourse markers, verbal markers of point of view, and meta-discursive expressions as markers of such strategy. These can appear alone or combined in a synergic or accumulative process whereby certain linguistic expressions orient the hearer on discourse structure...

  8. La presencia del inglés en la red de Internet en lengua española: las ofertas de empleo en www.monster.es

    Hooft, Andreu van
    In this paper we present the results of a corpus-based synchronic study on the presence of English in 208 jobs ads placed on the Spanish website www.monster.es published during the month of November 2011. The aims of this study were to identify the presence of anglicisms used in job ads, determine their presence and quantity and establish to what extent the presence of English depends on the following extra linguistic factors: industry activity, job level (high, intermediate or low) and type of organization (international or domestic). The results indicate that the percentage of job ads that contained at least one English word (87.5%) was significantly higher for the...

  9. Transitividad en el español de Chile: exploración desde la perspectiva sistémico-funcional

    Gutiérrez, Rosa María
    The purpose of this study is to describe, from the theoretical and methodological framework of the systemic functional grammar, the lexico-grammatical realization of the congruent models used to linguistically construct the representation of experience. This involves the identification and characterization of the realizing configurations, according to range scales, axis, delicacy, continuum of the lexicogrammar and probability of occurrence. For the latter characterization, a micro-corpus of child speech, collected from spontaneous speech, is used as observation context, under the assumption that this is the context in which the most congruent forms of interaction appear. The results, which constitute part of a larger project (FONDECYT 1121082), are presented in each of...

  10. Una propuesta de taxonomía de marcadores metadiscursivos para el discurso académicocientífico escrito en español

    Salas Valdebenito, Millaray
    Drawing on the reflexive model of metadiscourse (Ädel, 2006), the present study proposes a taxonomy of three types of metadiscourse markers, namely, Personal Metadiscourse (PM), Impersonal Metadiscourse (IM) and Metatext (MT). The proposed taxonomy is derived from a close manual analysis of 238 recent empirical research articles from three different disciplines (Medicine, Economics and Linguistics) from Spanish-medium journals indexed in Web of Science. PM encompasses linguistic expressions in which the participants of the communicative event (writer and/ or reader) are explicitly mentioned. IM comprises all references to the participants which are realized obliquely, by relying on an array of depersonalizing strategies. Last, MT groups all those expressions which refer...

  11. La contribución del oyente a la interacción oral en Español como Lengua Extranjera. Un estudio comparativo

    Pérez Ruiz, Javier
    El conocimiento de los factores que pueden impulsar la adquisición de la competencia comunicativa en una segunda lengua es un tema de gran relevancia investigadora por las consecuencias teóricas y didácticas que conlleva. Desafortunadamente, el papel del oyente en la comunicación oral en Español como Lengua Extranjera (ELE) ha sido uno de los factores menos estudiado. Ante esta situación, el propósito fundamental de este artículo es analizar las aportaciones que el oyente realiza en el desarrollo de la competencia comunicativa en ELE. Dos objetivos específicos conducen la investigación: por un lado, se describe la contribución de las señales verbales del oyente a la interacción oral en ELE. Por...

  12. Funciones gramaticales de la coma. Clasificación e implantación computacional

    Koza, Walter
    Objective of present paper is to classify the comma uses focused in grammatical aspects and from a computational linguistic perspective is proposed. From this objective, some theoretical aspects based on grammatical criteria are showed, and the following classification of the comma functions are established: (i) indicator comma: it points enumerations and ellipsis, (ii) bounding comma: it delimits incidental clauses (appositions, vocatives, etcetera), and (iii) comma for disambiguation: it avoids confusion in expressions that could present more than a interpretation. Afterwards, a formalization and a computational implementation are made with the objective of getting a method of automatic detection for comma functions. In relation to the computational work, the software...

  13. Análisis de Errores Asistido por Computador basado en un Corpus de Aprendientes de Español como Lengua Extranjera

    Ferreira Cabrera, Anita; Elejalde Gómez, Jessica; Vine Jara, Ana
    This paper presents a Computer Aided Error Analysis (CEA) study based on Spanish as a Foreign Language Learners’ Corpus. The corpus is made up of 84 summary texts: 40 of them are of expository modality, 22 narrative and 22 argumentative. These were written in Spanish by 22 international students from diverse university study programs with a B1 language proficiency level, enrolled in a b-learning Spanish as a foreign language course at Universidad de Concepcion, Chile (ele.udec.cl). The writing computerized tasks involved the production of 250-word-summaries based on scientific, historical and cultural topics that learners were asked to read. The methodology included Computer Aided Error Analysis and Computer Learner...

  14. Alfabetismos digitales para una escuela multicultural

    Moreno Herrero, Isidro; Muñoz, Valentín Gonzalo
    This article describes a proposal which is in keeping with one of the actions of our current research project: the adoption of linguistic support to promote the incorporation of allophone students (who can not communicate in the language of the host country) to the ordinary curriculum, and more concrete, the use of the new technologies as literacy tools, particularly the applications of the Web.2.0. It is made a brief review of the social and digital context in which the school is involved and a multiliteracy model that attends the linguistic and cultural diversity of the schools is proposed. Moreover, it also...

  15. Una visita con invitación: ¿por qué no convertirla en un proyecto de trabajo?

    Llamazares Prieto, María Teresa; Alonso-Cortés Fradejas, María Dolores
    In this article we explore the possibility of producing texts for pupils of pre-primary education based on the constructivist principle that the meaning of texts can be achieved through the application of various strategies and techniques. To demonstrate this, we present a written invitation as a sample text and then we outline the different task which were carried out by the pupils on this text as well as the different stages of the activities. We conclude that it is necessary to combine various communicative task which involve inferring the meaning of written language through graphical aspects of the text with...

  16. Alfabetização matemática e literatura infantil: possibilidades para uma prática pedagógica integrada

    Colins Silva, Fabio; Gonçalves Machado, Arthur; Gonçalves, Tadeu Oliver
    This paper aims to present, describe and discuss the integrated teaching math literacy and linguistic literacy through children's literature regarding specifically the teaching of geometry. Didactic proposals in this research approach the teaching of geometry (Space and Shape), specifically the skills related to the location and movement in space, recognition, composition and decomposition of plane figures and their elements (edge, vertex, side, etc.) from reading two Children's literature texts. The teaching experience was given by two sequences of activities built with the purpose of developing an integrated teaching math literacy and linguistic literacy in a multisseriate class composed of students...

  17. "Delos sos oios tan fuerte mientre lorando": un cambio sintáctico examinado a través de un corpus digitalizado

    Blake, Robert J.; Sánchez Lancis, Carlos Eliseo
    In this study, we extend the idea of a synchronic sociolinguistic continuum to a diachronic framework in order to examine the origin and evolution of a particular Spanish syntactic change - the possessive construction article + possessive adjective + noun, for example los sos oios - with data extracted from a digitalized corpus of early medieval notarial documents from the Sahagun Monastery on the border of Castile and Leon (9th to 12th centuries). These texts are written in a mixed or Latinate style that employs both Latin morphology and lexis along with other forms rendered in completely reformed, phonetic spellings...

  18. Dos problemas en el uso de corpus diacrónicos del español: perspectiva y comparabilidad

    Enrique-Arias, Andrés
    This paper addresses a number of methodological problems related to corpus-based research in language variation. It is shown through a number of case studies using data from Biblia medieval (a parallel corpus of Old Spanish bible translations) how this kind of research can profit from parallel texts. To begin with, the perspective afforded by parallel corpus methodology is more open as it is possible to analyze all the forms used to express contents in the source language. Likewise, parallel texts offer direct comparability of concrete examples across different historical periods, as translation equivalents are likely to be inserted in the...

  19. Corpus digitales y palabras gramaticales

    Garachana Camarero, Mar; Artigas Alvarez, Esther
    The aim of this paper is to address the advantages and disadvantages of working with electronic corpora to study the grammaticalization of verbal constructions in the history of Spanish. The data on which we base our study have been extracted from the corpora compiled by the Real Academia Española, i.e., corde and crea. These corpora lack lemmatization and tagging. Hence, when these corpora are consulted for a given expression, concordance searches often yield an unwieldy amount of irrelevant occurrences. Another difficulty we have encountered when working with these corpora, especially corde, has to do with the fact that, all too...

  20. Desarrollo y explotación del "Corpus de Documentos Españoles Anteriores a 1700" (CODEA)

    Sánchez-Prieto Borja, Pedro
    This paper aims to present the current status of the "Corpus de Documentos Españoles Anteriores a 1700" (CODEA, http://www.textoshispanicos.es) prepared by the "Grupo de Investigación de Textos para la Historia del Español" (GITHE) of the University of Alcalá. CODEA offers 1500 documents from different archives produced in all of the non-bilingual peninsular provinces of Spain, spanning from the 12th to the 17th centuries. The triple presentation (facsimile, paleographic transcription and edition with normalized spelling) facilitates its use in various disciplines, from palaeography to historical syntax. In the paper we also present further developments that will be available in the near...
