Major bleeding of the upper aerodigestive tract due to oral anticoagulant/antibiotic interactions

INTRODUCTION Although a well-known complication in certain medical specialties, major bleeding due to the interaction between oral anticoagulants and antibiotics has been rarely reported concerning the upper aerodigestive tract. We report three cases of life-threatening bleeding of the upper aerodigestive tract in a context of antibiotic therapy in patients treated with oral anticoagulants. CASE SERIES Three male patients under coumadin anticoagulation therapy presented major bleeding in three different contexts (epistaxis, peritonsillar abscess and postoperative course after total laryngectomy). Surgical intervention for hemostasis was required in all cases, with coagulation correction in two. Complications were severe anemia (2/3) and chronic heart failure (1/3). DISCUSSION/CONCLUSIONS Interactions between two drugs commonly used in otolaryngology can result in major bleeding. The goal of this article is to raise practitioners' awareness of a potentially fatal, although rare, complication. We also review the main preventive strategies.

A case-control study of hepatitis C virus and its interaction with hepatitis B virus on the development of hepatocellular carcinoma in the USA

Objective. The aim of this study was to assess the independent risk of hepatitis C virus (HCV) infection in the development of hepatocellular carcinoma (HCC). The independent risk of hepatitis B virus (HBV), its interaction with hepatitis C virus and the association with other risk factors were examined.^ Methods. A hospital-based case-control study was conducted between January 1994 and December 1995. We enrolled 115 pathologically confirmed HCC patients and 230 nonliver cancer controls, who were matched by age ($\pm$5 years), gender, and year of diagnosis. Both cases and controls were recruited from The University of Texas M. D. Anderson Cancer Center at Houston. The risk factors were collected through personal interviews and blood samples were tested for HCV and HBV markers. Univariate and multivariate analyses were performed through conditional logistic regression.^ The prevalence of anti-HCV positive is 25.2% in HCC cases compared to 3.0% in controls. The univariate analysis showed that anti-HCV, HBsAg, alcohol drinking and cigarette smoking were significantly associated with HCC, however, family history of cancer, occupational chemical exposure, and use of oral contraceptive were not. Multivariate analysis revealed a matched odds ratio (OR) of 10.1 (95% CI 3.7-27.4) for anti-HCV, and an OR of 11.9 (95% CI 2.5-57.5) for HBsAg. However, dual infection of HCV and HBV had only a thirteen times increase in the risk of HCC, OR = 13.9 (95% CI 1.3-150.6). The estimated population attributable risk percent was 23.4% for HCV, 12.6% for HBV, and 5.3% for both viruses. Ever alcohol drinkers was positively associated with HCC, especially among daily drinkers, matched OR was 5.7 (95% CI 2.1-15.6). However, there was no significant increase in the risk of HCC among smokers as compared to nonsmokers. The mean age of HCC patients was significantly younger among the HBV(+) group and among the HCV(+)/HBV(+) group, when compared to the group of HCC patients with no viral markers. The association between past histories of blood transfusion, acupuncture, tattoo and IVDU was highly significant among the HCV(+) group and the HBV(+)/HCV(+) group, as compared to HCC patients with no viral markers. Forty percent of the HCC patients were pathologically or clinically diagnosed with liver cirrhosis. Anti-HCV(+) (OR = 3.6 95% CI 1.5-8.9) and alcohol drinking (OR = 2.7 95% CI 1.1-6.7), but not HBsAg, are the major risk factors for liver cirrhosis in HCC patients.^ Conclusion. Both hepatitis B virus and hepatitis C virus were independent risk factors for HCC. There was not enough evidence to determine the interaction between both viruses. Only daily alcoholic drinkers showed increasing risk for HCC development, as compared to nondrinkers. ^

Oral or transdermal opioids for osteoarthritis of the knee or hip.

BACKGROUND Osteoarthritis is the most common form of joint disease and the leading cause of pain and physical disability in older people. Opioids may be a viable treatment option if people have severe pain or if other analgesics are contraindicated. However, the evidence about their effectiveness and safety is contradictory. This is an update of a Cochrane review first published in 2009. OBJECTIVES To determine the effects on pain, function, safety, and addiction of oral or transdermal opioids compared with placebo or no intervention in people with knee or hip osteoarthritis. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and CINAHL (up to 28 July 2008, with an update performed on 15 August 2012), checked conference proceedings, reference lists, and contacted authors. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials that compared oral or transdermal opioids with placebo or no treatment in people with knee or hip osteoarthritis. We excluded studies of tramadol. We applied no language restrictions. DATA COLLECTION AND ANALYSIS We extracted data in duplicate. We calculated standardised mean differences (SMDs) and 95% confidence intervals (CI) for pain and function, and risk ratios for safety outcomes. We combined trials using an inverse-variance random-effects meta-analysis. MAIN RESULTS We identified 12 additional trials and included 22 trials with 8275 participants in this update. Oral oxycodone was studied in 10 trials, transdermal buprenorphine and oral tapentadol in four, oral codeine in three, oral morphine and oral oxymorphone in two, and transdermal fentanyl and oral hydromorphone in one trial each. All trials were described as double-blind, but the risk of bias for other domains was unclear in several trials due to incomplete reporting. Opioids were more beneficial in pain reduction than control interventions (SMD -0.28, 95% CI -0.35 to -0.20), which corresponds to a difference in pain scores of 0.7 cm on a 10-cm visual analogue scale (VAS) between opioids and placebo. This corresponds to a difference in improvement of 12% (95% CI 9% to 15%) between opioids (41% mean improvement from baseline) and placebo (29% mean improvement from baseline), which translates into a number needed to treat (NNTB) to cause one additional treatment response on pain of 10 (95% CI 8 to 14). Improvement of function was larger in opioid-treated participants compared with control groups (SMD -0.26, 95% CI -0.35 to -0.17), which corresponds to a difference in function scores of 0.6 units between opioids and placebo on a standardised Western Ontario and McMaster Universities Arthritis Index (WOMAC) disability scale ranging from 0 to 10. This corresponds to a difference in improvement of 11% (95% CI 7% to 14%) between opioids (32% mean improvement from baseline) and placebo (21% mean improvement from baseline), which translates into an NNTB to cause one additional treatment response on function of 11 (95% CI 7 to 14). We did not find substantial differences in effects according to type of opioid, analgesic potency, route of administration, daily dose, methodological quality of trials, and type of funding. Trials with treatment durations of four weeks or less showed larger pain relief than trials with longer treatment duration (P value for interaction = 0.001) and there was evidence for funnel plot asymmetry (P value = 0.054 for pain and P value = 0.011 for function). Adverse events were more frequent in participants receiving opioids compared with control. The pooled risk ratio was 1.49 (95% CI 1.35 to 1.63) for any adverse event (9 trials; 22% of participants in opioid and 15% of participants in control treatment experienced side effects), 3.76 (95% CI 2.93 to 4.82) for drop-outs due to adverse events (19 trials; 6.4% of participants in opioid and 1.7% of participants in control treatment dropped out due to adverse events), and 3.35 (95% CI 0.83 to 13.56) for serious adverse events (2 trials; 1.3% of participants in opioid and 0.4% of participants in control treatment experienced serious adverse events). Withdrawal symptoms occurred more often in opioid compared with control treatment (odds ratio (OR) 2.76, 95% CI 2.02 to 3.77; 3 trials; 2.4% of participants in opioid and 0.9% of participants control treatment experienced withdrawal symptoms). AUTHORS' CONCLUSIONS The small mean benefit of non-tramadol opioids are contrasted by significant increases in the risk of adverse events. For the pain outcome in particular, observed effects were of questionable clinical relevance since the 95% CI did not include the minimal clinically important difference of 0.37 SMDs, which corresponds to 0.9 cm on a 10-cm VAS.

A STUDY OF THE ATTITUDES OF ELDERLY CONSUMERS TOWARD DENTAL CARE AND ORAL HEALTH

This paper describes a study of the attitudes of elderly consumers toward dental care and oral health. Four hundred and two respondents ages 60-97 were interviewed with a 62 item questionnaire. Attitudes were measured regarding: quality of care, sufficient utilization of care, priority of oral health, patient-provider interaction, individual control over health, powerful others control of health, and chance as the locus of control over health. Analysis of variance was performed on the sample of males and females separately. Fifty-four hypotheses were tested on each sex. Race and self-concept were excellent predictors of attitude for both sexes and SES (socioeconomic status) and self-reported health were good predictors for females. There was no statistically significant relationship between the frequency with which the elderly utilize dental care and their attitudes toward the quality of care they receive. Foremost reason for non-utilization was that of no felt need. Those selecting this reason were likely to be Anglo females, wearers of dentures, in good health. Those selecting cost as the foremost reason for non-utilization were Black, in fair health, of either sex, missing some teeth, but with no dentures. Overall attitudes toward quality of dental care were positive, despite the fact that this group was exposed to dental care in its infancy. This may suggest that the elderly recognize the importance of technological advances in dentistry. Women with low income and education levels were more likely to have positive attitudes about quality of care than other females. Attitudes about interaction between patient and provider were overall negative. The sample scored high on individual control over health, and scored lower, but nonetheless positively, on feelings that persons other than themselves are most essential to maintaining health. Overall these elderly persons did not agree that they relied on chance in matters of health. Those who did choose this locus were female, with lower SES and health status. Though males scored high on internal control of health, those with lowest scores were Mexican-American or had never been married. Sex and ethnicity were the best predictors of attitude across all measures in the study.^

Association of p21/p27 polymorphisms with risk of HPV16-associated oral squamous cell carcinoma

The increasing incidence of oral squamous cell carcinoma (OSCC) among young adults has been associated with sexually transmitted infection of human papillomavirus (HPV), particularly HPV16. Given the roles of p21 (WAF1/Cip1/CDKN1A) and p27 (Kip1/CDKNIB) in cell-cycle regulation and of HPV16 E6 and E7 oncoproteins in p53 degradation and pRb inactivation, the effect of HPV16 L1 seropositivity and three putatively functional single-nucleotide polymorphisms (SNPs) of p21 (p21 C70T and p21 C98A) and p27 (p27 T109G), individually and in combination, on the risk of OSCC was evaluated in a hospital-based case-control study of 327 cases and 401 cancer-free controls who were frequency-matched on age, gender and smoking status. Individuals with HPV16 L1 seropositivity had an overall 3-fold increased risk of having OSCC than those with HPV16 seronegativity. The increased risk of HPV16-associated OSCC was particularly found among younger people (aged ≤ 50 years), males, never smokers, never drinkers and oropharynx cancer patients. None of three p21 and p27 polymorphisms alone was significantly associated with risk of OSCC. Individuals with variant genotypes for both p21 polymorphisms were more likely to have OSCC than individuals with wild-type genotypes or variant genotypes for either one of the p21 polymorphisms (adjusted OR, 1.4; 95% CI, 0.9-2.1). There was a borderline significant or significant interaction between the p21 C70T, combined p21 and combined p21/p27 genotypes and HPV16 L1 seropositivity on risk of OSCC. The three studied p21 and p27 polymorphisms, individually or in combination, did not appear to have an effect on HPV16-related clinical outcomes (overall and disease-free survival and tumor recurrence). Despite the fact that the exact biological mechanism remains to be explored, these findings suggest possible involvement of p21variants, particularly the p21 C70T variant genotypes (CT/TT), in the etiology of HPV16-associated OPSCC. Further large and functional studies are required to validate the findings.^

Inter-acción : lenguaje oral y pedagogía teatral

Esta investigación aplicada, mantuvo la línea de trabajo que se viene sosteniendo desde el período 05/07 y pretendió profundizar el sesgo de la pedagogía teatral orientada a interaccionar con aprendizajes lingüísticos, fundamentalmente del discurso oral. Se trabajó con un grupo de muestra acotado, probando una secuencia pedagógico-didáctica que diera resultados que permitieran afirmar que el lenguaje Teatro posibilita, en la escuela, la investigación guiada de “los modos en los que el afuera interviene en la conformación del adentro" y facilita a los alumnos desarrollar su oralidad y gestualidad en el nivel interaccional, impactando positivamente en su desempeño académico y social.

User Experience in Human-Technology Interaction. Communication, context and evaluation methodology

En esta Tesis se presentan dos líneas de investigación relacionadas y que contribuyen a las áreas de Interacción Hombre-Tecnología (o Máquina; siglas en inglés: HTI o HMI), lingüística computacional y evaluación de la experiencia del usuario. Las dos líneas en cuestión son el diseño y la evaluación centrada en el usuario de sistemas de Interacción Hombre-Máquina avanzados. En la primera parte de la Tesis (Capítulos 2 a 4) se abordan cuestiones fundamentales del diseño de sistemas HMI avanzados. El Capítulo 2 presenta una panorámica del estado del arte de la investigación en el ámbito de los sistemas conversacionales multimodales, con la que se enmarca el trabajo de investigación presentado en el resto de la Tesis. Los Capítulos 3 y 4 se centran en dos grandes aspectos del diseño de sistemas HMI: un gestor del diálogo generalizado para tratar la Interacción Hombre-Máquina multimodal y sensible al contexto, y el uso de agentes animados personificados (ECAs) para mejorar la robustez del diálogo, respectivamente. El Capítulo 3, sobre gestión del diálogo, aborda el tratamiento de la heterogeneidad de la información proveniente de las modalidades comunicativas y de los sensores externos. En este capítulo se propone, en un nivel de abstracción alto, una arquitectura para la gestión del diálogo con influjos heterogéneos de información, apoyándose en el uso de State Chart XML. En el Capítulo 4 se presenta una contribución a la representación interna de intenciones comunicativas, y su traducción a secuencias de gestos a ejecutar por parte de un ECA, diseñados específicamente para mejorar la robustez en situaciones de diálogo críticas que pueden surgir, por ejemplo, cuando se producen errores de entendimiento en la comunicación entre el usuario humano y la máquina. Se propone, en estas páginas, una extensión del Functional Mark-up Language definido en el marco conceptual SAIBA. Esta extensión permite representar actos comunicativos que realizan intenciones del emisor (la máquina) que no se pretende sean captadas conscientemente por el receptor (el usuario humano), pero con las que se pretende influirle a éste e influir el curso del diálogo. Esto se consigue mediante un objeto llamado Base de Intenciones Comunicativas (en inglés, Communication Intention Base, o CIB). La representación en el CIB de intenciones “no claradas” además de las explícitas permite la construcción de actos comunicativos que realizan simultáneamente varias intenciones comunicativas. En el Capítulo 4 también se describe un sistema experimental para el control remoto (simulado) de un asistente domótico, con autenticación de locutor para dar acceso, y con un ECA en el interfaz de cada una de estas tareas. Se incluye una descripción de las secuencias de comportamiento verbal y no verbal de los ECAs, que fueron diseñados específicamente para determinadas situaciones con objeto de mejorar la robustez del diálogo. Los Capítulos 5 a 7 conforman la parte de la Tesis dedicada a la evaluación. El Capítulo 5 repasa antecedentes relevantes en la literatura de tecnologías de la información en general, y de sistemas de interacción hablada en particular. Los principales antecedentes en el ámbito de la evaluación de la interacción sobre los cuales se ha desarrollado el trabajo presentado en esta Tesis son el Technology Acceptance Model (TAM), la herramienta Subjective Assessment of Speech System Interfaces (SASSI), y la Recomendación P.851 de la ITU-T. En el Capítulo 6 se describen un marco y una metodología de evaluación aplicados a la experiencia del usuario con sistemas HMI multimodales. Se desarrolló con este propósito un novedoso marco de evaluación subjetiva de la calidad de la experiencia del usuario y su relación con la aceptación por parte del mismo de la tecnología HMI (el nombre dado en inglés a este marco es Subjective Quality Evaluation Framework). En este marco se articula una estructura de clases de factores subjetivos relacionados con la satisfacción y aceptación por parte del usuario de la tecnología HMI propuesta. Esta estructura, tal y como se propone en la presente tesis, tiene dos dimensiones ortogonales. Primero se identifican tres grandes clases de parámetros relacionados con la aceptación por parte del usuario: “agradabilidad ” (likeability: aquellos que tienen que ver con la experiencia de uso, sin entrar en valoraciones de utilidad), rechazo (los cuales sólo pueden tener una valencia negativa) y percepción de utilidad. En segundo lugar, este conjunto clases se reproduce para distintos “niveles, o focos, percepción del usuario”. Éstos incluyen, como mínimo, un nivel de valoración global del sistema, niveles correspondientes a las tareas a realizar y objetivos a alcanzar, y un nivel de interfaz (en los casos propuestos en esta tesis, el interfaz es un sistema de diálogo con o sin un ECA). En el Capítulo 7 se presenta una evaluación empírica del sistema descrito en el Capítulo 4. El estudio se apoya en los mencionados antecedentes en la literatura, ampliados con parámetros para el estudio específico de los agentes animados (los ECAs), la auto-evaluación de las emociones de los usuarios, así como determinados factores de rechazo (concretamente, la preocupación por la privacidad y la seguridad). También se evalúa el marco de evaluación subjetiva de la calidad propuesto en el capítulo anterior. Los análisis de factores efectuados revelan una estructura de parámetros muy cercana conceptualmente a la división de clases en utilidad-agradabilidad-rechazo propuesta en dicho marco, resultado que da cierta validez empírica al marco. Análisis basados en regresiones lineales revelan estructuras de dependencias e interrelación entre los parámetros subjetivos y objetivos considerados. El efecto central de mediación, descrito en el Technology Acceptance Model, de la utilidad percibida sobre la relación de dependencia entre la intención de uso y la facilidad de uso percibida, se confirma en el estudio presentado en la presente Tesis. Además, se ha encontrado que esta estructura de relaciones se fortalece, en el estudio concreto presentado en estas páginas, si las variables consideradas se generalizan para cubrir más ampliamente las categorías de agradabilidad y utilidad contempladas en el marco de evaluación subjetiva de calidad. Se ha observado, asimismo, que los factores de rechazo aparecen como un componente propio en los análisis de factores, y además se distinguen por su comportamiento: moderan la relación entre la intención de uso (que es el principal indicador de la aceptación del usuario) y su predictor más fuerte, la utilidad percibida. Se presentan también resultados de menor importancia referentes a los efectos de los ECAs sobre los interfaces de los sistemas de diálogo y sobre los parámetros de percepción y las valoraciones de los usuarios que juegan un papel en conformar su aceptación de la tecnología. A pesar de que se observa un rendimiento de la interacción dialogada ligeramente mejor con ECAs, las opiniones subjetivas son muy similares entre los dos grupos experimentales (uno interactuando con un sistema de diálogo con ECA, y el otro sin ECA). Entre las pequeñas diferencias encontradas entre los dos grupos destacan las siguientes: en el grupo experimental sin ECA (es decir, con interfaz sólo de voz) se observó un efecto más directo de los problemas de diálogo (por ejemplo, errores de reconocimiento) sobre la percepción de robustez, mientras que el grupo con ECA tuvo una respuesta emocional más positiva cuando se producían problemas. Los ECAs parecen generar inicialmente expectativas más elevadas en cuanto a las capacidades del sistema, y los usuarios de este grupo se declaran más seguros de sí mismos en su interacción. Por último, se observan algunos indicios de efectos sociales de los ECAs: la “amigabilidad ” percibida los ECAs estaba correlada con un incremento la preocupación por la seguridad. Asimismo, los usuarios del sistema con ECAs tendían más a culparse a sí mismos, en lugar de culpar al sistema, de los problemas de diálogo que pudieran surgir, mientras que se observó una ligera tendencia opuesta en el caso de los usuarios del sistema con interacción sólo de voz. ABSTRACT This Thesis presents two related lines of research work contributing to the general fields of Human-Technology (or Machine) Interaction (HTI, or HMI), computational linguistics, and user experience evaluation. These two lines are the design and user-focused evaluation of advanced Human-Machine (or Technology) Interaction systems. The first part of the Thesis (Chapters 2 to 4) is centred on advanced HMI system design. Chapter 2 provides a background overview of the state of research in multimodal conversational systems. This sets the stage for the research work presented in the rest of the Thesis. Chapers 3 and 4 focus on two major aspects of HMI design in detail: a generalised dialogue manager for context-aware multimodal HMI, and embodied conversational agents (ECAs, or animated agents) to improve dialogue robustness, respectively. Chapter 3, on dialogue management, deals with how to handle information heterogeneity, both from the communication modalities or from external sensors. A highly abstracted architectural contribution based on State Chart XML is proposed. Chapter 4 presents a contribution for the internal representation of communication intentions and their translation into gestural sequences for an ECA, especially designed to improve robustness in critical dialogue situations such as when miscommunication occurs. We propose an extension of the functionality of Functional Mark-up Language, as envisaged in much of the work in the SAIBA framework. Our extension allows the representation of communication acts that carry intentions that are not for the interlocutor to know of, but which are made to influence him or her as well as the flow of the dialogue itself. This is achieved through a design element we have called the Communication Intention Base. Such r pr s ntation of “non- clar ” int ntions allows th construction of communication acts that carry several communication intentions simultaneously. Also in Chapter 4, an experimental system is described which allows (simulated) remote control to a home automation assistant, with biometric (speaker) authentication to grant access, featuring embodied conversation agents for each of the tasks. The discussion includes a description of the behavioural sequences for the ECAs, which were designed for specific dialogue situations with particular attention given to the objective of improving dialogue robustness. Chapters 5 to 7 form the evaluation part of the Thesis. Chapter 5 reviews evaluation approaches in the literature for information technologies, as well as in particular for speech-based interaction systems, that are useful precedents to the contributions of the present Thesis. The main evaluation precedents on which the work in this Thesis has built are the Technology Acceptance Model (TAM), the Subjective Assessment of Speech System Interfaces (SASSI) tool, and ITU-T Recommendation P.851. Chapter 6 presents the author’s work in establishing an valuation framework and methodology applied to the users’ experience with multimodal HMI systems. A novel user-acceptance Subjective Quality Evaluation Framework was developed by the author specifically for this purpose. A class structure arises from two orthogonal sets of dimensions. First we identify three broad classes of parameters related with user acceptance: likeability factors (those that have to do with the experience of using the system), rejection factors (which can only have a negative valence) and perception of usefulness. Secondly, the class structure is further broken down into several “user perception levels”; at the very least: an overall system-assessment level, task and goal-related levels, and an interface level (e.g., a dialogue system with or without an ECA). An empirical evaluation of the system described in Chapter 4 is presented in Chapter 7. The study was based on the abovementioned precedents in the literature, expanded with categories covering the inclusion of an ECA, the users’ s lf-assessed emotions, and particular rejection factors (privacy and security concerns). The Subjective Quality Evaluation Framework proposed in the previous chapter was also scrutinised. Factor analyses revealed an item structure very much related conceptually to the usefulness-likeability-rejection class division introduced above, thus giving it some empirical weight. Regression-based analysis revealed structures of dependencies, paths of interrelations, between the subjective and objective parameters considered. The central mediation effect, in the Technology Acceptance Model, of perceived usefulness on the dependency relationship of intention-to-use with perceived ease of use was confirmed in this study. Furthermore, the pattern of relationships was stronger for variables covering more broadly the likeability and usefulness categories in the Subjective Quality Evaluation Framework. Rejection factors were found to have a distinct presence as components in factor analyses, as well as distinct behaviour: they were found to moderate the relationship between intention-to-use (the main measure of user acceptance) and its strongest predictor, perceived usefulness. Insights of secondary importance are also given regarding the effect of ECAs on the interface of spoken dialogue systems and the dimensions of user perception and judgement attitude that may have a role in determining user acceptance of the technology. Despite observing slightly better performance values in the case of the system with the ECA, subjective opinions regarding both systems were, overall, very similar. Minor differences between two experimental groups (one interacting with an ECA, the other only through speech) include a more direct effect of dialogue problems (e.g., non-understandings) on perceived dialogue robustness for the voice-only interface test group, and a more positive emotional response for the ECA test group. Our findings further suggest that the ECA generates higher initial expectations, and users seem slightly more confident in their interaction with the ECA than do those without it. Finally, mild evidence of social effects of ECAs was also found: the perceived friendliness of the ECA increased security concerns, and ECA users may tend to blame themselves rather than the system when dialogue problems are encountered, while the opposite may be true for voice-only users.

Invariantes del pensamiento en los arquitectos de Madrid. Primera década del siglo XXI. Una historia de transmisión oral

Invariantes del pensamiento en los arquitectos de Madrid. Primera década del siglo XXI. Una historia de transmisión oral es una Tesis Doctoral que parte de la elaboración de un archivo documental inédito, archivo que aglutina los testimonios de los más importantes arquitectos de Madrid presentes durante los primeros diez años del siglo XXI. Estos testimonios se recogen ordenadamente a modo de conversaciones transcritas, reflexiones puntuales y audios. La incorporación de los audios al trabajo documental permite comprobar a futuros investigadores, de manera directa, la certeza de las conclusiones o, incluso, establecer interpretaciones distintas. Los documentos sonoros son el germen de este trabajo. La Tesis Doctoral ordena e interpreta los testimonios en su apartado de ANÁLISIS/ DESARROLLO permitiendo entender a través de constantes demostraciones un hilo conductor del pensamiento en los arquitectos de Madrid. Se trata de una Tesis Doctoral que se entiende como un documento vivo, abierto y que gracias a su carácter inédito descubre matices y reflexiones de los arquitectos nunca antes recogidos en otros trabajos. Se ha conseguido reunir y ordenar por primera vez la voz y el pensamiento de los más importantes arquitectos de Madrid, muchos de ellos ya fallecidos. Se ha establecido un árbol genealógico ordenado y completo de los arquitectos de referencia indiscutibles desde el año 1939. Se ha conseguido reunir en un solo documento a los arquitectos y personajes más citados y recurrentes en el discurso de los arquitectos de Madrid, pudiendo constatar así sus referentes culturales más utilizados. Se ha descubierto y argumentado un pensamiento común dividido en cuatro conceptos: Oportunidad, Orden, Compromiso y Contención. Se produce una aproximación al arquitecto y a su pensamiento de la manera más natural y espontánea. Las grabaciones nos permitirán introducirnos, sin imposturas, no solo en el fondo, sino también en la forma de lo que se comunica, en el cómo. Una vez seleccionados los documentos sonoros más adecuados para el objetivo de este trabajo se ha procedido a su transcripción al papel. En este proceso se depura el lenguaje y se liman defectos de forma, al mismo tiempo se resumen las conversaciones y se recogen solo los comentarios más interesantes. En el proceso de transcripción, así como en la elección de las preguntas, existe una labor editorial, la aplicación de un criterio a la hora de seleccionar, resumir, corregir, completar, etc. Para abordar las conversaciones se ha recurrido a la bibliografía de referencia de cada uno de los arquitectos. Una vez transcritas las entrevistas, se establece una valoración crítica, una aproximación teórica al tema principal de la conversación. Bien puede tratarse de una reflexión sobre el arquitecto y su trabajo o sobre algunas de las opiniones o temas vertidos durante la charla. Para situar a cada uno de los arquitectos que se citan, se ha establecido un apartado genealógico completo donde cada uno se coloca en su lugar correspondiente conforme a sus apariciones en los textos principales de la historiografía reciente desde Carlos Flores hasta el año 2010. Esta Tesis Doctoral es un testigo de la diversidad de pensamientos y actitudes así como de las coincidencias. Las conversaciones mantenidas, las reflexiones y las opiniones vertidas al respecto han tocado reiteradamente muchos temas que aparecerán ordenados en el ANÁLISIS/DESARROLLO y en el apartado DESCRIPTORES. A partir de estos y otros temas genéricos, los pensamientos se aglutinan en torno a cuatro puntos que resumen las actitudes y los planteamientos conceptuales más recurrentes y coincidentes. Estos cuatro puntos definen de una manera concreta al arquitecto de Madrid. Oportunidad, Orden, Compromiso y Contención. Identidad generada a través de una historia de transmisión oral, desde los arquitectos de las primeras generaciones de posguerra hasta hoy. ABSTRACT Invariable thought in the architects of Madrid. First decade of the XXI century. A history of oral transmission is a Doctoral Thesis that starts with the development of a new documentary file, a file which brings together the testimonies of the most important architects of Madrid present during the first ten years of this century. These testimonies include conversations, punctual reflections and audio bites. Incorporating audio allows future researchers to check certain conclusions directly or even to have different interpretations. Sound bites are the seed of this work. This Doctoral Thesis orders and interprets the testimonies in the ANALYSIS / DEVELOPMENT section, through which a common thread of thought in Madrid architects can be ascertained. This doctoral thesis is meant as a living, open document, which, thanks to its unprecedented nature, discovers nuances and reflections of architects that had never been collected in previous studies. It has brought together and sorted for the first time the voice and thoughts of the most important architects of Madrid, many of them already deceased. It has established an orderly and comprehensive reference guide to the most important architects since 1939. It has brought together in one document the most cited and recurring architects and characters in the discourse of the architects of Madrid, which enables us to observe the cultural references they used the most. We have discovered and put forward a common thought divided into four concepts: Opportunity, Order, Commitment and Containment. The architect and his thoughts are revealed as naturally and spontaneously as possible. The recordings allow us to ascertain, without impositions, not only the substance but also the form of what is communicated. After selecting the most appropriate sound bites for the purpose of this work, we have proceeded to transcribe them to paper. In this process the language has been purified and formal defects have been dealt with, and at the same time the conversations have been summarized and only the most interesting comments have been kept. The transcription process and the choice of questions entails editorial work, applying a criterion when selecting, summarizing, amending, supplementing, etc. To address the conversations, the bibliographic reference of each of the architects has been used. Once the interviews have been transcribed, a critical appraisal and a theoretical approach to the main topic of conversation are established. It may be a reflection on the architect and his work or some of the views or issues discussed during the talk. In order to place each of the cited architects, a complete family tree has been devised in which each architect is situated according to his appearances in the main text of recent historiography, from Carlos Flores until 2010. This Doctoral Thesis is a witness to the diversity of thoughts, attitudes and coincidences. The conversations, reflections and opinions expressed in this regard have repeatedly touched many issues that will be sorted in the ANALYSIS/DEVELOPMENT and the KEYWORDS section. From these and other generic issues, thoughts coalesce around four points which summarize the attitudes and the most recurrent and similar conceptual approaches. These four points define the architect of Madrid in a concrete way. Opportunity, order, engagement and containment. An identity generated by a history of oral transmission, from the architects of the first post-war generations until today.

Programa de estimulação de linguagem oral para crianças com atraso de linguagem

A aquisição e o desenvolvimento da linguagem são primordiais na vida de uma criança, especialmente porque a linguagem possibilita a comunicação com o mundo, sendo um dos principais meios de integração social. Por isso é de grande importância que se assegure que as crianças tenham um bom desenvolvimento da linguagem e, quando necessário, uma boa intervenção em suas dificuldades. Atualmente, em linguagem infantil no Brasil, discute-se diferentes abordagens terapêuticas, mas se verifica a necessidade da elaboração de programas terapêuticos estruturados, confeccionados com qualidade técnica e cientifica que, estimulem as diversas habilidades de linguagem, de forma a considerar as especificidades de cada criança, a fim de minimizar as dificuldades na comunicação destas. Programas de intervenção deste tipo norteariam os fonoaudiólogos a planejarem suas terapias e proporcionaria maior eficácia no processo terapêutico. O objetivo principal deste trabalho foi elaborar, e testar a aplicabilidade de um programa de estimulação de linguagem oral para crianças com atraso de linguagem, na faixa-etária de 3 a 6 anos. Para isso, após a elaboração do programa de estimulação, o mesmo foi julgado por dois juízes, fonoaudiólogos mestres em Linguagem com experiência em Intervenção em Linguagem Infantil, quanto: (a) coerência das estratégias propostas com relação a meta de estimulação; e, (b) com relação ao nível de dificuldade de tais estratégias para o perfil das crianças. Em seguida o programa foi aplicado em 10 crianças com atraso de linguagem sem outros comprometimentos (sensoriais e/ou neurológicos), este programa foi composto de 20 sessões terapêuticas, realizadas com frequência de três vezes por semana, durando em média 60 minutos. As crianças realizaram uma pré-testagem e foram submetidas ao programa de estimulação proposto, ao termino foi realizada uma pós-testagem. Nesta avaliação pré e pós-estimulação, foram avaliados a organização fonológica, vocabulário receptivo e expressivo, habilidades pragmáticas e habilidades psicolinguísticas da criança. O programa foi julgado como adequado pelos juízes e as crianças submetidas à ele tiveram desempenho de acordo com esperado durante as sessões de estimulação. Observou-se também melhora estatisticamente significante (p<0,05) na pós-testagem na Linguagem Global, Linguagem Receptiva, Linguagem Expressiva, Vocabulário Expressivo, Memória de trabalho fonológica e habilidades comunicativas verbais. Conclui-se que o programa atingiu seus objetivos, sendo que o mesmo pode vir a nortear e aprimorar a estimulação fonoaudiológica nos casos de alterações em linguagem infantil, enfatizando a estimulação dos níveis fonético-fonológico, sintático, semântico-lexical e pragmático da linguagem e habilidades psicolinguisticas.

An approach to verbal humor in interaction

I propose a method to study interactional ironic humorous utterances in Spanish. In GRIALE research group consider this method can be applied to humorous ironic utterances in different textual genres, from the violation of conversational principles. Futhermore, we present the General Theory of Verbal Humor proposed by Attardo that it will be taken in our analysis. Therefore, I study irony and humor in examples of conversations from Peninsular Spanish real sample corpuses (COVJA, Corpus de conversaciones coloquiales [Corpus of Colloquial Conversations] and CREA, Corpus de Referencia del Español Actual [Reference Corpus of Present-Day Spanish]). In this article, I will focus on the application of this theory to humorous ironic statements which arise in conversation and examine the effects caused by them, which will additionally verify if irony and humor coexist in the same conversational exchange with a communicative aim and conversational strategies.

Theory-of-mind development in oral deaf children with cochlear implants or conventional hearing aids

Background: In the context of the established finding that theory-of-mind (ToM) growth is seriously delayed in late-signing deaf children, and some evidence of equivalent delays in those learning speech with conventional hearing aids, this study's novel contribution was to explore ToM development in deaf children with cochlear implants. Implants can substantially boost auditory acuity and rates of language growth. Despite the implant, there are often problems socialising with hearing peers and some language difficulties, lending special theoretical interest to the present comparative design. Methods: A total of 52 children aged 4 to 12 years took a battery of false belief tests of ToM. There were 26 oral deaf children, half with implants and half with hearing aids, evenly divided between oral-only versus sign-plus-oral schools. Comparison groups of age-matched high-functioning children with autism and younger hearing children were also included. Results: No significant ToM differences emerged between deaf children with implants and those with hearing aids, nor between those in oral-only versus sign-plus-oral schools. Nor did the deaf children perform any better on the ToM tasks than their age peers with autism. Hearing preschoolers scored significantly higher than all other groups. For the deaf and the autistic children, as well as the preschoolers, rate of language development and verbal maturity significantly predicted variability in ToM, over and above chronological age. Conclusions: The finding that deaf children with cochlear implants are as delayed in ToM development as children with autism and their deaf peers with hearing aids or late sign language highlights the likely significance of peer interaction and early fluent communication with peers and family, whether in sign or in speech, in order to optimally facilitate the growth of social cognition and language.

Parent-child interaction and road behaviour:An exploratory study

The relationship between parent-child interaction and child pedestrian behaviour was investigated by comparing parent-child communication to road-crossing behaviour. Forty-four children and their parents were observed carrying out a communication task (the Map Task), and were covertly filmed crossing roads around a university campus. The Map Task provided measures of task focus and sensitivity to another's current knowledge, which we predicted would be reflected in road-crossing behaviour. We modelled indices of road behaviour with factor scores derived from a principal-component analysis of communication features, and background variables including the age, sex and traffic experience of the child, and parental education. A number of variables were significantly related to road crossing, including the age and sex of the child, the length of the conversation, and specific conversational features such as the checking and clarification of uncertain information by both parent and child. The theoretical and practical implications of the findings are discussed.
