Pictobana: Una herramienta para la comunicación con niñosautistas

Introducción: Los avances actuales en el campo de las TICs han permitido un importante impulso en el desarrollo de sistemas que traducen texto plano en español en pictogramas. Sin embargo, las soluciones actuales no pueden ser comprendidas por una persona con dificultades del lenguaje en Cuba, debido a que algunas terminologías no están presentes en el lenguaje cotidiano. Objetivo: Desarrollar el modelo Pictobana para el análisis semántico de un Pictotraductor que integre la semántica del lenguaje cubano. Métodos: El modelo fue desarrollado aplicando técnicas de procesamiento del lenguaje natural. Se realiza un análisis lingüístico con el objetivo de proporcionar las mejores representaciones posibles de los textos en pictogramas. Resultados: El modelo es implementado en una aplicación web que proporciona una herramienta que ayuda a promover las competencias y habilidades de comunicación a personas con dificultades del habla en Cuba y a sus familiares. Conclusiones: Las pruebas realizadas mediante experimentos y criterio de expertos, demuestran que el analizador desarrollado, aumenta la ajustabilidad de los pictogramas al contexto y a la semántica, aminorando la incoherencia y la ambigüedad semántica del futuro sistema.

Introduction: Current advances in the field of ICTs have allowed an important boost in the development of systems that allow translating plain text in Spanish into pictograms. However, the current solutions cannot be understood by a person with language difficulties in Cuba because some terminologies are not present in everyday language. Objective: To develop the Pictobana model for the semantic analysis of a Pictotranslator that integrates the semantics of the Cuban language. Methods: The model was developed by applying natural language processing techniques. A linguistic analysis was carried out with the aim of providing the best possible representations of the texts in pictograms. Results: The model is implemented in a web application that provides a tool that helps promote communication skills and abilities for people with speech difficulties and their families in Cuba. Conclusions: The tests carried out through experiments and expert criteria show that the developed analyzer increases the adjustability of the pictograms to the context and the semantics, reducing the incoherence and semantic ambiguity of the future system.

El estudio de los efectos de la modalidad lingüística en el léxico mental / The study of the effects of linguistic modality on the mental lexicon

Resumen El estudio se cuestiona sobre un abordaje fructífero en el estudio de los efectos de la modalidad lingüística (de señas versus oral) en la organización de la memoria semántica. Para responder la pregunta de investigación, un aspecto central es definir criterios y procedimientos capaces de distinguir entre los factores transportados por la modalidad lingüística de los que le son propios. Entre los primeros, se encuentran la edad de exposición a la lengua natural y su distribución funcional, etaria o geográfica. Entre los aspectos propios de la modalidad se incluyen la iconicidad y el grado de concreción/abstracción de las piezas léxicas. Se sugiere centrarse en el uso de dicho gradiente para evocar dominios conceptuales. Si lo concreto/abstracto es un continuo, entonces hay que preguntarse qué forma de organización es predominante en el léxico mental de las poblaciones señantes u oyentes y qué factores modulan el perfil de esa organización.

Abstract The efforts to understand the relationship of the meaning of a lexical piece to the object to which it refers, the relationship between the lexical pieces and the concepts, and the understanding of the meanings shared between two speakers who use the same lexical pieces have all constituted major problems for the semantic memory models. According to contemporary literature, perceptual-motor, linguistic, and social information have different weights in the formation of concepts, whether concrete or abstract, stored in the aforementioned memory. Regardless of the models developed so far, it is interesting to note that semantic knowledge is represented by various ways of relating the concepts and the types of relationships between them. In this context, studies in sign languages and comparative studies between spoken and sign languages are scarce. Thus, little is known about the effect of linguistic modality on the semantic networks. After all, the theory on semantic networks and norms for the production of features has been grounded on theories of language and its processing adjusted to spoken languages. As the incorporation of the sign language and the Deaf population has shown in other psycholinguistic and linguistic topics, the importance of including these languages and populations, and comparatives with spoken languages, might increase the explanatory power of the theory to account for the universal and contextual aspects of language and its processing. In this effort, there is a latent risk: the linguistic modality can be only a vehicle for more well-known or studied cross-modal variables (e. g., age of acquisition, functional distribution of language, size of the available lexicon, etc.). If it is considered that languages are not stored together, but similar processes can occur in them, it is essential to find out what may be a singular feature of each modality (spoken versus sign) that might ground differentiated processes. Considering the high iconicity of the sign languages and the possibility of a high concreteness of the lexical pieces in the sign language as distinctive features -not collapsible into well-known variables such as the aforementioned-, this article suggests a careful approach to avoid the aforementioned risk in the study of the effects of the linguistic modality (sign versus oral) in the organization of semantic memory. Since perceptual-motor and social information are the main sources of iconicity, a balanced instrument is necessary in the evocation of perceptual-motor, social, and linguistic information. Repeated free word association tasks seem like an appropriate paradigm for a suggested approach. The reasons for this are that, by not censoring the types of response, then free association tasks allow capturing all kinds of concepts (concrete or abstract), all kinds of semantic relationships/organization (paradigmatic versus thematic) and all kinds of processes (comparison versus interaction). This type of task therefore makes it possible to collect meanings related to linguistic information and non-linguistic experience because affective and experiential information is accessible by doing the task in different repetitions. The approach and the tool are exemplified by an ongoing comparative study between Deaf signing and hearing populations. The partial findings of this study also serve to focus on the expected effects of the difference in iconicity and the level of concreteness/abstractness of the lexical pieces of each linguistic modality; namely, the differences between an abstract and a concrete conceptualization of the conceptual domains. Taxonomic and introspective labels might appear as indicative of paradigmatic relationships, of a taxonomic organization, and of underlying comparison processes. On the other hand, the situational and entity labels, indicative of syntagmatic relationships, of a thematic organization and of underlying interaction processes, might suggest a predominantly concrete organization.

Current vision on diagnosis and comprehensive care in hepatic encephalopathy.

The first clinical guidelines on hepatic encephalopathy were published in 2009. Almost 14 years since that first publication, numerous advances in the field of diagnosis, treatment, and special condition care have been made. Therefore, as an initiative of the Asociación Mexicana de Gastroenterología A.C., we present a current view of those aspects. The manuscript described herein was formulated by 24 experts that participated in six working groups, analyzing, discussing, and summarizing the following topics: Definition of hepatic encephalopathy; recommended classifications; epidemiologic panorama, worldwide and in Mexico; diagnostic tools; conditions that merit a differential diagnosis; treatment; and primary and secondary prophylaxis. Likewise, these guidelines emphasize the management of certain special conditions, such as hepatic encephalopathy in acute liver failure and acute-on-chronic liver failure, as well as specific care in patients with hepatic encephalopathy, such as the use of medications and types of sedation, describing those that are permitted or recommended, and those that are not.

Estandarización de la batería de Evaluación de la Memoria Semántica (EMSEA) en adultos mayores institucionalizados de Lima / Standardization of the Semantic Memory Evaluation Battery (EMSEA) in institutionalized elderly adults of Lima

Objetivo: Determinar si la memoria semántica es un factor asociado al deterioro cognitivo en adultos mayores de Lima. Método: Se aplicaron la batería de Evaluación de la Memoria Semántica para Adultos Mayores (EMSEA), el Mini-mental State Examination (MMSE) y otros instrumentos que fueron utilizados como criterios externos. La muestra estuvo constituida por 158 adultos mayores de Lima Metropolitana entre 60 a 95 años de edad. La EMSEA diferencia entre una muestra normal y clínica, siendo la sensibilidad de 80% y la especificidad de 100% para un punto de corte de 251. Se evidencia validez concurrente y se demuestra un modelo EMSEA de dos factores. La confiabilidad fue adecuada con valor Alfa de Cronbach de .75 y Theta de .80. Resultados: Los datos descriptivos señalaron un 28% de prevalencia de deterioro cognitivo y 23% de nivel de memoria semántica bajo. El modelo predictivo señala que tres áreas de la memoria semántica están asociadas al deterioro cognitivo con un R2 de 25%, quedando el modelo establecido por: Verificación, denominación de dibujos y analogías. Conclusión: Se concluye que la batería EMSEA presenta evidencia de validez de criterio y constructo, así como consistencia interna. (AU)

Objective: To determine if semantic memory is a factor associated with cognitive impairment in older adults in Lima. Method: The Semantic Memory Assessment Battery for Older Adults (EMSEA), the Mini-mental State Examination (MMSE) and other instruments that were used as external criteria were applied. The sample consisted of 158 older adults from Metropolitan Lima between 60 and 95 years of age. EMSEA differentiates between a normal and clinical sample, with a sensitivity of 80% and a specificity of 100% for a cut-off point of 251. Concurrent validity is evidenced and a two-factor EMSEA model is demonstrated. Cronbach's Alpha value is .75 and Theta is .80. Results: Descriptive data indicated a 28% prevalence of cognitive impairment and a 23% low semantic memory level. The predictive model indicates that three areas of semantic memory are associated with cognitive impairment with an R2 of 25%, leaving the model established by: Verification, naming of drawings and analogies. Conclusion: It is concluded that the EMSEA battery presents evidence of criterion and construct validity, internal consistency and a predictive. (AU)

Research strategy search in Cochrane Library, MEDLINE via PubMed, Scopus, Web of Science, EMBASE databases. Selection criteria comparative, longitudinal or case-control clinical studies that included analysis of the expressive and receptive vocabulary of children with stuttering aged between 2 and 9 years. Results most of the analyzed studies report a relationship between lexical development or performance and stuttering in children, however there is no consense about the relationship between greater or lesser lexical development. Conclusion there is not enough evidence to relate stuttering and lexical development. More studies are needed in order to understand the relationship between lexical performance and stuttering in children.

Desarrollo y validación de una tarea experimental de Memoria Episódica verbal en español / Development and validation of an experimental verbal Episodic Memory task in Spanish

RESUMEN Propósito Elaborar y validar una tarea experimental de memoria episódica verbal en español. Método Se elaboraron seis bloques de codificación: tres profundos y tres superficiales, cado uno con distintas demandas de esfuerzo cognitivo. Los bloques fueron revisados por cuatro jueces expertos y examinados en una aplicación piloto. Se evaluó la concordancia respecto a si la tarea permitía manipular combinadamente el nivel de procesamiento y el esfuerzo cognitivo durante la codificación incidental de palabras, así como la claridad de las instrucciones, ejemplos y dinámica de trabajo. Resultados Variables como la disponibilidad léxica, metría y fuerza de asociación fueron útiles para diferenciar el esfuerzo cognitivo entre cada bloque. Los jueces concordaron que los bloques de procesamiento admiten una manipulación combinada del nivel de procesamiento y esfuerzo cognitivo y que las instrucciones son precisas. Luego del pilotaje, los participantes concordaron que las instrucciones, ejemplos y forma de trabajo eran fácil de comprender y realizar. Conclusión Los resultados proporcionan evidencia de validez relacionada con el contenido para la tarea experimental propuesta, transformándose con ello en una alternativa viable de considerar en investigaciones orientadas a identificar factores ambientales que contribuyan a compensar los defectos que muestra la memoria episódica con la edad.

ABSTRACT Purpose To develop and validate an experimental verbal episodic memory task in Spanish. Methods Six encoding blocks were elaborated, three deep and three superficial, each one with different demands of cognitive effort. The blocks were reviewed by four expert judges and tested in a pilot application. The agreement was assessed on whether the task allowed combined processing level and cognitive effort to be manipulated during incidental encoding of words, as well as clarity of instructions, examples, and workflow. Results Variables such as lexical availability, metrics, and strength of association were useful to differentiate the cognitive effort between each block. The judges agreed that the processing blocks allowed a combined manipulation of the level of processing and cognitive effort and that the instructions are precise. After the pilot, the participants agreed that the instructions, examples, and way of working were easy to understand and perform. Conclusion The results provide evidence of validity related to the content for the proposed experimental task, thus becoming a viable alternative to consider in research aimed at identifying environmental factors that contribute to compensating the defects shown by episodic memory with age.

"Migrânea" or "enxaqueca": A historical and semantic review / "Migrânea" ou "enxaqueca": uma revisão histórica e semântica

Introduction: Headache is as old as the emergence of man on earth. A classification for headaches has been suggested for many centuries. After the invention of writing, numerous words were created to designate different types of headache. Objective: The objective of this review was to discuss the historical and etymological aspects of the terms "migrânea" and "enxaqueca". Methods: This study was an integrative review using articles with historical data on the etymology of the terms "migrânea" and "enxaqueca" and their evolution over the years. Results: The terms "migrânea" and "enxaqueca" have Greek and Arabic origins, respectively. Both describe a neurological syndrome characterized by headache and other associated symptoms. Usually, sufferers of this disease are more familiar with the term "enxaqueca" and confuse it with headache, while health professionals prefer the term "migrânea". Conclusions: After so many years that the term "migrânea" has been used, it would be a step backwards to use the term "enxaqueca" again, especially because "migrânea" has been adopted by young neurologists, including those from other specialties.

Introdução:A dor de cabeça é tão antiga quanto o surgimento do homem na terra. Uma classificação para dores de cabeça tem sido sugerida há muitos séculos. Após a invenção da escrita, inúmeras palavras foram criadas para designar diferentes tipos de dor de cabeça. Objetivo: O objetivo desta revisão foi discutir os aspectos históricos e etimológicos dos termos "migranânea" e "enxaqueca". Métodos: Este estudo foi uma revisão integrativa utilizando artigos com dados históricos sobre a etimologia dos termos "migranânea" e "enxaqueca" e sua evolução ao longo dos anos. Resultados: Os termos "migranânea" e "enxaqueca" têm origem grega e árabe, respectivamente. Ambos descrevem uma síndrome neurológica caracterizada por dor de cabeça e outros sintomas associados. Normalmente, quem sofre desta doença conhece mais o termo "enxaqueca" e confunde-o com dor de cabeça, enquanto os profissionais de saúde preferem o termo "migranânea". Conclusões: Depois de tantos anos de uso do termo "migranânea", seria um retrocesso usar novamente o termo "enxaqueca", até porque "migranânea" tem sido adotada por jovens neurologistas, inclusive de outras especialidades.

Tres tareas para la exploración de la fluidez verbal: evidencias de su fiabilidad test-retest en adultos argentinos / Three tasks for the exploration of verbal fluency: evidence of test-retest reliability in Argentine adults

Introducción: Las tareas de fluidez fonológica y semántica son de uso frecuente en la evaluación neuropsicológica por su fácil aplicación y buena sensibilidad al deterioro cognitivo. En Argentina es limitado el cuerpo de evidencia psicométrica para dichas tareas, con especial desconocimiento de la estabilidad temporal de sus medidas. La producción psicométrica es aún menor para la variante fluidez de acción (emisión de verbos en infinitivo en un minuto). En efecto, este estudio analiza la fiabilidad test-retest de tres tareas de fluidez en adultos argentinos. Sujetos y métodos: La muestra se compuso de 85 argentinos (medida de edad, 63,7) de población general no clínica, un 75,3% mujeres, de nivel de instrucción medio-alto. Se efectuó un diseño longitudinal-prospectivo administrando tareas de fluidez fonológica, semántica y de acción en dos momentos distintos con un intervalo hasta de cuatro meses. Se analizó el coeficiente de correlación intraclase (CCI), método estadístico sugerido para estudios de fiabilidad test-retest. Para interpretar el CCI se adoptaron los criterios de Fleiss. Resultados: Las tareas de fluidez fonológica y semántica demostraron buena fiabilidad, con un CCI de 0,77 y 0,79. La fluidez de acción obtuvo excelente fiabilidad, con un CCI de 0,9. Conclusión: Las tareas de fluidez relevadas poseen apropiada estabilidad temporal, por lo que se sugiere su uso en investigaciones neuropsicológicas prospectivas (cuando se evalúe el lenguaje en distintos momentos) o cuando se requiera un seguimiento de la evolución de pacientes afásicos en neurorrehabilitación. Basándose en su excelente fiabilidad, se recomienda utilizar con más frecuencia la variante de acción.(AU)

Introduction: The phonological and semantic verbal fluency tasks are frequently used in neuropsychological assessment due to their easy application and good sensitivity to dementia. In Argentina, the psychometric evidence for these tasks is limited, with a special lack of knowledge of the temporal stability of its measurements. The psychometric production is even lower for the action fluency variant (emission of verbs in the infinitive in one minute). In effect, this research analyzes the test-retest reliability of three verbal fluency tasks in Argentine adults. Subjects and methods: The sample was made up of 85 Argentine (average age, 63.7 years), 75,3% women and with a medium-high educational level. A prospective longitudinal design was carried out, administering phonological, semantic and action fluency tasks at two different times with an interval of up to four months. The intraclass correlation coefficient (ICC), a statistical method suggested for test-retest reliability studies, was analyzed. For the interpretation of the ICC, the Fleiss criteria were adopted. Results: The phonological and semantic fluency tasks showed good reliability, with ICCs of 0.77 and 0.79. The fluidity of action variant yielded ICC of 0.90, indicating excellent reliability. Conclusions: All fluency tasks have appropriate temporal stability, and their use is recommended when prospective neuropsychological research is planned (with language evaluation at di fferent times) or as a method of monitoring the evolution of aphasic patients undergoing neurorehabilitation. Based on its excellent reliability, it is recommended to use the action variant more frequently.(AU)

Mediación parental en el uso de tecnologías móviles en niños y niñas costarricenses: Una aproximación metodológica mixta / The meaning of concepts dealing with basic emotions in children and adults

Resumen Aunque las emociones básicas son consideradas universales, su significado varía según las culturas y los grupos sociales. En el marco de la construcción social de los significados, aquí se analizan y comparan las representaciones semánticas de seis emociones básicas (alegría, tristeza, enojo, miedo, sorpresa, asco) activadas por 78 niños (9 a 11 años) y 78 adultos (20 a 40 años). En base a una tarea de producción de atributos semánticos, se construyó la representación semántica asociada a cada emoción para cada rango etario. Luego, utilizando la metodología provista por el análisis de redes sociales (ARS), se analizó la calidad intrínseca y las diferencias en cantidad y tipos de atributos, estructura de las redes, densidad y nivel de entropía, y el uso de la definición por negación. Los resultados indicaron que los mapas semánticos de niños y mayores demuestran que los adultos producen mayor cantidad y diversidad de atributos que los niños, pero que ambas poblaciones comparten el núcleo del significado de los conceptos evaluados. Asimismo, muestra que la escolarización conduce a la generación de más atributos taxonómicos, que en los niños prevalecen los atributos introspectivos, que la densidad y la entropía revelan cómo los conceptos se vinculan entre sí diferencialmente en ambas poblaciones y finalmente que, frente a la dificultad para encontrar definidoras de pertenencia a una clase, los niños recurren a operaciones de contraste categorial. Entre las redes semánticas de adultos y de niños se encuentran continuidades y divergencias. En ambos grupos se encuentran separadas las emociones positivas de las negativas, lo cual es consistente con las teorías que sostienen la importancia de la valencia hedónica en la comprensión de las emociones.

Abstract Although basic emotions are considered universal, their representation, associations and meaning vary among cultures and social groups. Within the framework of the socio-constructivist theory, where the meanings develop in the social context, this paper analyzes and compares the semantic representations of six basic emotions (Joy, Sadness, Anger, Fear, Surprise and Disgust), evoked by 78 children between 9 and 11 years old and 78 adults between 20 and 40 years old. Participants had to list a series of properties/features for each concept in a Property Listing Task (PLT). With the lists produced by the participants, their frequencies and other statistical properties were calculated, and the matrix of distances between concepts was obtained from the vectors defined by each of them. Thus, using the six aforementioned emotions as stimuli, the semantic representation associated with each emotion was elaborated for each age range. Once these were obtained, an analysis was carried out to evaluate the intrinsic quality and the differences in: (1) quantity and types of features produced; (2) structure of each of the semantic networks obtained, both by means of quadratic assignment procedure (QAP) and hierarchical clustering algorithms; (3) network density (that describes the portion of the potential connections in a network that are actual connections) and entropy level (that describe the level of randomness and the amount of information encoded in a network); (4) comparative use of definition by negation; (5) qualitative analysis of the features associated with each emotional concept. To carry out the bulk of these activities and analysis, we used the tools and procedures provided by Social Network Analysis (SNA). As a result: (1) regarding the number of features, adults produced significantly more associations. A chi-square analysis found significant differences between groups in the type of features evoked, with a primacy of taxonomic for adults and introspective for children; (2) the quadratic assignment procedure found a significant level of association of .59 between the two age groups. The groupings performed at the lowest level of demand for linkage between cluster members distinguish positive emotions from negative ones; higher levels of demand begin to disaggregate the groupings: first fear and sadness are separated, then anger, then the dyad constituted by both versions of disgust. The emotion of greater commonality between children and adults is joy; (3) the density of the total network is higher in children than in adults, and the concepts of joy, disgust and sadness present a lower entropy in children than in adults; (4) Children produce considerably more definitions by the negative than adults; (5) the most similar emotion between both groups is joy and the most dissimilar is disgust. In children, disgust responds to gustatory stimuli, in adults it is used with social metaphorical value. The results obtained show the semantic representation of basic emotions in children and adults, finding both continuities (e. g. joy) and divergences (e. g. disgust) associated with the context and life experience. In both age groups, positive and negative emotions are found to be separated, which is consistent with theories on the importance of hedonic valence in the understanding of emotions. There are also differences in categorization, either more thematically or taxonomically oriented.

Dificultades en la comprensión lectora de niños con TDAH / Difficulties in Reading Comprehension in Children With ADHD

Resumen Los niños diagnosticados con trastorno por déficit de atención e hiperactividad (TDAH) experimentan múltiples dificultades durante el aprendizaje de la lectura, en especial con los componentes del lenguaje que permiten un buen desarrollo del proceso lector. En este sentido, el interés de este trabajo fue evaluar la sintaxis y la semántica como componentes del lenguaje fundamentales para la comprensión lectora. Se aplicó la batería PROLEC-R a 37 niños (entre 6 - 13 años) diagnosticados con TDAH y se analizaron los índices principales junto a los baremos para determinar en qué componente lingüístico se ubica la mayor complejidad. Los resultados sugieren que los niños tienen mayores dificultades en lo sintáctico, referido a estructurar oraciones y aplicar los signos de puntuación. Por lo tanto, si se refuerza el componente sintáctico los niños con TDAH, podrían mejorar en la comprensión lectora.

Abstract Children diagnosed with ADHD experience multiple difficulties in learning to read, especially with the language components that allow a good development of the reading process. In this sense, the interest of this work was to evaluate syntax and semantics as fundamental components of language for reading comprehension. The PROLEC-R battery was applied to 37 children between 6 and 13 years old diagnosed with ADHD, and the main indexes were analyzed together with the scales to determine in which linguistic component was the greater complexity located. The results suggest that children in the sample have greater difficulties in syntax, referring to sentence structure and punctuation. Therefore, if the syntactic component is reinforced, children with ADHD could probably improve their reading comprehension.

Definición de consumo de hombres universitarios. Exploración desde las redes semánticas naturales / Definition of university men's consumption. Exploration from natural semantic networks

Resumen Frente al dominio del neoliberalismo en las sociedades contemporáneas, las posibilidades de consumo resultan abrumadoras, en tanto mecanismo de configuración identitaria y evidencia de nuevas formas de inclusión/exclusión de los sujetos respecto de los grupos sociales. Esta investigación aborda un segmento de la sociedad chilena que no escapa de esta lógica: los hombres jóvenes. Los jóvenes, en general, constituyen un segmento propenso al riesgo financiero, con altos niveles de endeudamiento, al menos en la sociedad chilena. En este escenario, el artículo explora los significados de consumo que construyen hombres universitarios de pregrado, de tres áreas de formación profesional de una universidad de la Región de La Araucanía (Chile). Se utiliza una metodología cualitativa, aplicando la técnica de redes semánticas naturales. La muestra estuvo conformada por estudiantes de las áreas de las Ciencias Sociales, Ciencias de la Salud y Ciencias de la Ingeniería, de edades entre 18 y 24 años, con un total de 51 sujetos. Los resultados indican una red semántica general abundante, cuyo núcleo está representado por la palabra "alimentarse", seguido por significados asociados a dinero, comprar y necesidad, que dan cuenta de la dimensión material del consumo. Son relevantes, además, los conceptos asociados a drogas y alcohol. A propósito de los hallazgos, se sugiere explorar la relación de la alimentación con el cuerpo masculino, así como la posesión de bienes materiales y las orientaciones al éxito en los hombres jóvenes, sobre todo en lo referente al proceso de construcción de masculinidades juveniles.

Abstract In the face of the dominance of neoliberalism in Western societies the possibilities of consumption are overwhelming. This type of societies are associated with a consumerist culture and lifestyle, where the capacity of consumption is the fundamental criterion of inclusion/exclusion of the subjects. Consumption intervenes significantly in the construction of people's personal and social identity. The desires and longings generated by the consumer society are related to the acquisition of lifestyles. In this sense, subjects give meaning to objects and experiences. The interest of this research is in young people. Young people represent a segment of interest for the economic market; therefore, they constitute a group that is financially in risk. The high levels of indebtedness of the youth population in Chile must be considered. Specifically, men handle money from a young age and carry out certain paid activities, especially in popular sectors. Men are projected as active consumers in the economic market, an area where the traditional gender division has diminished, directing men to production and women to consumption. On the other hand, empirical evidence shows the association between masculinities and material possessions, money and orientation to success. It is also possible to mention a relative scarcity of studies linking men and consumption in Latin America. In this context, the present article explores the meaning of consumption as constructed by university men in three areas of professional training, who are pursuing undergraduate careers, in the Araucanía Region. A qualitative methodology is used to achieve the research objective, applying the technique of natural semantic networks. A case study is carried out. The sample was conformed by students of Social Sciences (18 subjects), Health Sciences (15 subjects) and Engineering Sciences (18 subjects), aged between 18 and 24 years old, with a total of 51 subjects. All students are from a private university in the Araucanía Region, Chile.

Representação da informação sobre a covid-19: rede semântica de títulos de artigos na Web of Science / Representation of the information about covid-19: semantic network of article titles in the Web of Science / Representación de la información sobre covid-19: red semántica de títulos de artículos en la Web of Science

Este artigo busca representar as relações entre termos de maior relevância nas pesquisas indexadas na Web of Science sobre o novo coronavírus (SARS-CoV-2), de dezembro de 2019 a maio de 2020. Caracterizada como pesquisa exploratória e descritiva, o método de investigação e os procedimentos técnicos adotados são fundamentados na teoria do conceito, de Ingetraut Dahlberg, para a análise conceitual, e na abordagem de análise de redes sociais e complexas para análise estrutural da rede semântica de títulos de artigos criada. Os resultados apontaram uma rede de estrutura topológica caracterizada como mundo pequeno, com uma certa quantidade de conexões similares. O termo 'covid-19' apresenta transitividade alta em grupos fortemente conectados, os quais compreendem termos de domínios do conhecimento distintos e, por vezes, pouco relacionados no contexto disciplinar da ciência. A relação conceitual entre os termos é funcional. Concluiu-se que a interconexão entre termos de diferentes domínios do conhecimento forma grupos de termos emergentes, potencializando a urgência de pesquisas interdisciplinares para a compreensão do termo em destaque neste trabalho ­ 'covid-19'.

This article seeks to represent the relationships between the most relevant terms of the researches about the new coronavirus (SARS-CoV-2) indexed in the Web of Science from 2019 December to 2020 May. Characterized as an exploratory and descriptive research, the investigation method and technical procedures are based on the Concept Theory, by Ingetraut Dahlberg, for the conceptual analysis, and on the Social Network Analysis approach as well as on complex networks, for the structural analysis of the semantic network created from article titles. The results showed a network with a topological structure characterized as a small world, with some similar connections. The term 'covid-19' presents high transitivity in strongly connected groups, which comprise terms from different domains of knowledge and, sometimes, little related in the disciplinary context of the science. The conceptual relationship between the terms is functional. It was concluded that the interconnection between terms from different domains of knowledge generates groups of emerging terms, enhancing the urgency of interdisciplinary researches to understand the term that in this work is in focus ­ 'covid-19'.

Este artículo busca representar las relaciones entre los términos más relevantes en las investigaciones sobre el nuevo coronavirus (SARS-CoV-2) indexadas en la Web of Science desde diciembre de 2019 hasta mayo de 2020. Caracterizada como una investigación exploratoria y descriptiva, el método de investigación y los procedimientos técnicos practicados se basan en la teoría del concepto, de Ingetraut Dahlberg, para el análisis conceptual, y en el enfoque de análisis de redes sociales y de redes complejas, para el análisis estructural de la red semántica de títulos de artículos creada. Los resultados mostraron una red con una estructura topológica caracterizada como un mundo pequeño, con algunas conexiones similares. El término 'covid-19' presenta una alta transitividad en grupos fuertemente conectados, que comprenden términos de diferentes dominios del conocimiento y, en ocasiones, poco relacionados en el contexto disciplinario de la ciencia. La relación entre los términos es funcional. Se concluyó que la interconexión entre términos de diferentes dominios del conocimiento forma grupos de términos emergentes, lo que aumenta la urgencia de investigaciones interdisciplinarias para comprender el término destacado en este trabajo: 'covid-19'.

Construindo nós: paralelos e lições entre HIV/aids e covid-19 a partir da análise de redes semânticas no Twitter / Building knots: parallels and lessons between HIV/aids and covid-19 from the analysis of semantic networks on Twitter / Construyendo nudos: paralelismos y lecciones entre el VIH/sida y covid-19 del análisis de redes semánticas en Twitter

O presente artigo busca analisar postagens na rede social digital Twitter que contêm os termos 'HIV/aids' e 'covid-19' publicadas em abril de 2021, quando o Ministério da Saúde amplia a vacinação contra a covid-19 para pessoas com HIV/aids. Nosso objetivo foi o de comparar os dois acontecimentos epidemiológicos do país, evidenciar paralelos, subjetividades e lições a partir do corpus. Para tanto, optamos por um método quantiqualitativo de análise de redes semânticas baseada na coleta de conteúdos digitais, identificandose os pares ou o conjunto de palavras que mais se conectam, formando redes de significações análogas, denominadas clusters. Como resultado, identificamos a polarização político-partidária dos comentários sobre covid-19 e HIV/aids no Twitter, a reemergência dos estigmas associados a grupos específicos, como de homossexuais e asiáticos, o espalhamento em larga escala de desinformação sobre as duas doenças, revelando um campo de tensões e de disputas narrativas e midiáticas como ferramenta 'necropolítica'.

This article seeks to analyze posts on the digital social network Twitter containing the terms 'HIV/aids' and 'covid-19' published in April 2021, when the Ministry of Health expands vaccination against covid-19 for people with HIV/aids. Our objective was to compare the two epidemiological events in the country, highlighting parallels, subjectivities and lessons from the corpus. In order to do that, we chose a quanti-qualitative method of analysis of semantic networks based on the collection of digital content, identifying the pairs or sets of words that most connect, forming networks of analogous meanings, called clusters. As a result, we identified the political-partisan polarization of comments on covid-19 and HIV/aids on Twitter, the re-emergence of stigmas associated with specific groups, such as homosexuals and Asians, the largescale spread of misinformation about the two diseases, revealing a field of tensions and narrative and media disputes as a 'necropolitical' tool.

Nuestro objetivo fue comparar los dos eventos epidemiológicos en el país, destacando paralelos, subjetividades y lecciones del corpus. Por ello, optamos por un método cuanticualitativo de análisis de redes semánticas basado en la recolección de contenido digital, identificando los pares o conjuntos de palabras que más conectan, formando redes de significados análogos, llamados clusters. Como resultado, identificamos la polarización político-partidista de los comentarios sobre el covid-19 y el VIH/sida en Twitter, el resurgimiento de estigmas asociados con grupos específicos, como los homosexuales y los asiáticos, la difusión a gran escala de información errónea sobre las dos enfermedades, revelando un campo de tensiones y disputas narrativas y mediáticas como herramienta 'necropolítica'.

Maestras de preescolar: características reconocidas en niños y niñas con aptitudes sobresalientes / Preschool teachers: recognized characteristics in gifted children / Professores de pré-escolar: características reconhecidas em meninos e meninas excepcionais

Resumen (analítico) El presente trabajo tuvo como objetivo identificar las características que las profesoras de preescolar reconocían en las niñas y los niños con aptitudes sobresalientes. Es una investigación cuantitativa, transversal y exploratoria. Participaron 58 profesoras de preescolar. Se empleó la técnica de redes semánticas naturales modificadas a través de cuatro preguntas estímulo: qué características tienen los niños con aptitud sobresaliente en el área cognitiva, en el área crea-tiva, en el área psicomotriz y área socioemocional. Los resultados mostraron que las profesoras lograron reconocer algunos rasgos de los niños sobresalientes que coinciden con lo reportado en la litera-tura, lo que sugiere que ellas pueden ser un elemento clave en la detección de la población si se les proporcionan los instrumentos apropiados con las características del alumnado sobresaliente.

Abstract (analytical) This study had the objective of identifying characteristics that preschool teachers recognize in gifted boys and girls through a quantitative, cross-sectional and exploratory investigation. A total of 58 preschool teachers participated in the research. A modified natural semantic networks technique was used by asking four stimulus questions: What characteristics do gifted children have in the cognitive area?; in the creative area?; in the psychomotor area; and in the socio-emotional area. The results showed that the teachers were able to recognize some characteristics of gifted children that coincide with what is reported in scientific literature. This suggests that they may be a key element in detec-ting the population of gifted children if they are provided with the appropriate instruments outlining the characteristics of outstanding students.

Verbal fluency in school-aged Spanish children: analysis of clustering and switching organizational strategies, employing different semantic categories and letters / Fluidez verbal en niños españoles en edad escolar: análisis de las estrategias organizativas de agrupación y cambio, empleando diferentes categorías semánticas y letras

The verbal fluency task is a measure of cognitive flexibility and search strategy within the lexicon and semantic topic. The use of organizational strategies was tested in healthy Spanish children divided in two groups: group 1 of younger children and group 2 of older children introducing different letters and semantic categories. Semantic fluency was greater than phonological fluency in both age groups. In addition, older children showed better performance of both fluencies than younger children. From the phonological analyses, younger children evoked more word with the PMR letter group than with the FAS one. Moreover, an improvement of semantic fluency associated with the animal's category faced to meals and drink was observed only in the younger children group. In respect to organizational strategies, older children used more switches specifically in FAS group and more clusters for the meals or drinks category compared with the older children group. The relationships between the number of words evoked and the number of clusters and switches for both VF tasks were significant and positive. These data suggest that the type of letter and the semantic category employed in the VF evaluation modulate the verbal fluency performance in both groups of age.

La tarea de fluidez verbal es una medida de flexibilidad cognitiva y estrategia de búsqueda dentro del contenido léxico y semántico. Se evaluó el uso de estrategias organizativas en niños españoles sanos divididos en dos grupos: grupo 1 de niños más pequeños y grupo 2 de niños mayores introduciendo diferentes letras y categorías semánticas. La fluidez semántica fue mayor que la fluidez fonológica en ambos grupos de edad. Además, los niños mayores mostraron un mejor rendimiento de ambas fluencias que los niños más pequeños. A partir de los análisis fonológicos, los niños más pequeños evocaron más palabras con el grupo de letras PMR que con el de FAS. Además, se observó una mejora de la fluidez semántica asociada con la categoría animales frente a la categoría comidas y bebidas únicamente en el grupo de niños más pequeños. Con respecto a las estrategias organizativas, los niños mayores utilizaron más cambios, específicamente en el grupo FAS y más agrupamientos para la categoría de comidas o bebidas, en comparación con el grupo de niños mayores. Las relaciones entre el número de palabras evocadas y el número de agrupamientos y cambios para ambas tareas de VF fueron significativas y positivas. Estos datos sugieren que el tipo de letra y la categoría semántica empleada en la evaluación de la VF modulan el rendimiento en fluidez verbal en ambos grupos de edad.(AU)

Ocular fixations modulate audiovisual semantic congruency when standing in an upright position / Las fijaciones oculares modulan la congruencia semántica audiovisual cuando el cuerpo está en una posición erguida

Abstract Introduction: Multisensory audiovisual semantic congruency is the process by which visual information is perceived as integrated to auditory stimuli, because both coincide in terms of simultaneity and semantic correspondence. This study was aimed at establishing whether visual percepts, which semantically correspond to auditory stimuli, are associated with ocular fixations in modulating bottom-up areas while keeping a body posture alignment between the up-direction and the idiotropic axes, as well as in another orientation corresponding to a vectorial opposition between the up-direction and the head idiotropic axis. Method: Two groups (one for each position) were selected from a sample of 88 people. A bistable image was presented on a screen of a fixed 120 Hz eye-tracker device, providing background auditory stimuli so as to establish semantic congruencies and their relations to ocular fixations. Results: It was found that audiovisual semantic congruency is associated with fixations when idiotropic vectors are aligned with the up direction. Fixations manifested in bottom-up modulating areas are not associated with multisensory audiovisual semantic congruency when the head idiotropic vector is parallel with the gravity vector. Eye fixations decrease significantly if the head idiotropic axis is aligned with the gravity vector. Conclusion: It is concluded that body position can affect visual perceptual processes involved in the occurrence of semantic congruency.

Resumen Introducción: La congruencia semántica audiovisual es el proceso por el cual información de una modalidad sensorial visual se percibe como integrada a estímulos auditivos, porque coinciden en términos de simultaneidad y correspondencia semántica. Este estudio tuvo por objeto establecer si los perceptos visuales que se corresponden semánticamente a estímulos auditivos están asociados con las fijaciones oculares realizadas en áreas de modulación bottom-up, tanto en una postura corporal definida por la alineación entre la dirección vertical hacia arriba y los ejes vectoriales idiotrópicos, como en otra orientación definida por una oposición vectorial entre la vertical hacia arriba y el eje idiotrópico de la cabeza. Método: Dos grupos fueron seleccionados (uno por cada posición), tomados de una muestra de 88 personas. Los datos se obtuvieron por medio de un dispositivo fijo de registro de movimientos oculares de 120 Hz. Una imagen biestable se presentó, proporcionando estímulos auditivos de fondo para producir congruencias semánticas y establecer su relación con las fijaciones oculares. Resultados: Se encontró que la congruencia semántica audiovisual está asociada con áreas de fijación ocular cuando los vectores idiotrópicos están alineados con la dirección vertical ascendente. Las fijaciones oculares en áreas de modulación bottom-up no están asociadas con la congruencia semántica audiovisual cuando el vector idiotrópico de la cabeza está alineado con el vector gravitacional. En esta última posición, la cantidad de fijaciones oculares es significativamente menor. Conclusión: La posición del cuerpo puede afectar procesos perceptuales visuales que, a su vez, inciden en el efecto de congruencia semántica.

Covid-19 knowledge graphs in Health Communication and Information / Gráficos de conhecimento para Covid-19 em Comunicação e Informação sobre Saúde / Gráficos de conocimiento Covid-19 en Comunicación e Información de Salud

This commentary discusses recent developments in 'knowledge graph' technology over the course of the Covid-19 pandemic. Recently experiencing a surge in popularity, knowledge graphs are technologies that assist with data integration through structured metadata modeling. Researchers tag and collate vast amounts of diverse data using knowledge graphs, yet problems related to semantic drift and more salient issues related to the political economy of information and communication technologies persist. Researchers should anticipate that the semantics of these Covid-19 knowledge graphs can change over time. Equally important, researchers should also consider all stakeholders involved, including those stakeholders that might be excluded.

Este comentário discute desenvolvimentos recentes na tecnologia de 'gráficos de conhecimento' durante o curso da pandemia de Covid-19. Gráficos de conhecimento, que vêm tendo um aumento de popularidade, são tecnologias que auxiliam com a integração de dados através de modelamento estruturado de metadados. Pesquisadores rotulam e agregam vastas quantidades de dados diversos usando gráficos de conhecimento, entretanto persistem problemas relacionados a variações semânticas e questões mais salientes relacionadas à economia política de tecnologias de informação e comunicação. Os pesquisadores devem prever que a semântica desses gráficos de conhecimento para Covid-19 pode variar com o tempo. Igualmente importante, os pesquisadores devem também considerar todas as partes interessadas envolvidas, incluindo as que poderiam ser excluídas.

Recientemente experimentando un aumento en popularidad, los gráficos de conocimiento son tecnologías que ayudan a la integración de datos a través del modelado de metadatos estructurados. Los investigadores etiquetan y recopilan grandes cantidades de datos diversos utilizando gráficos de conocimiento, pero persisten los problemas relacionados con la deriva semántica y cuestiones más importantes relacionadas con la economía política de las tecnologías de la información y la comunicación. Los investigadores deben prever que la semántica de estos gráficos de conocimiento de Covid-19 puede cambiar con el tiempo. También es importante que los investigadores consideren a todas las partes interesadas involucradas, incluso las que podrían quedar excluidas.

How the diversity of human concepts of nature affects conservation of biodiversity.

Protecting nature has become a global concern. However, the very idea of nature is problematic. We examined the etymological and semantic diversity of the word used to translate nature in a conservation context in 76 of the primary languages of the world to identify the different relationships between humankind and nature. Surprisingly, the number of morphemes (distinct etymological roots) used by 7 billion people was low. Different linguistic superfamilies shared the same etymon across large cultural areas that correlate with the distribution of major religions. However, we found large differences in etymological meanings among these words, echoing the semantic differences and historical ambiguity of the contemporary European concept of nature. The principal current Western meaning of nature in environmental public policy, conservation science, and environmental ethics-that which is not a human artifact-appears to be relatively rare and recent and to contradict the vision of nature in most other cultures, including those of pre-Christian Europe. To avoid implicit cultural bias and hegemony-and thus to be globally intelligible and effective-it behooves nature conservationists to take into account this semantic diversity when proposing conservation policies and implementing conservation practices.

Cómo Afecta la Diversidad de los Conceptos Humanos de la Naturaleza a la Conservación de la Biodiversidad Resumen La protección de la naturaleza se ha vuelto una preocupación a nivel mundial; sin embargo, la misma idea de naturaleza es problemática. Examinamos la diversidad etimológica y semántica de la palabra que se utiliza para traducir la palabra nature en un contexto de conservación en los 76 lenguajes primarios del mundo y así identificar las diferentes relaciones entre la humanidad y la naturaleza. Sorprendentemente, el número de morfemas (raíces etimológicas distintas) usado por siete mil millones de personas fue bajo. Las diferentes superfamilias lingüísticas compartieron etimologías a lo largo de grandes áreas culturales que se correlacionan con la distribución de las religiones más importantes. Sin embargo, encontramos diferencias importantes en los significados etimológicos entre estas palabras, reflejando las diferencias semánticas y la ambigüedad histórica del concepto europeo contemporáneo de naturaleza. El principal significado occidental actual de nature dentro de la política ambiental pública, las ciencias de la conservación y la ética ambiental - aquello que no es un artefacto humano - parece ser relativamente raro y reciente, además de que contradice la visión de la naturaleza que tienen la mayoría de las demás culturas, incluyendo a aquellas de la Europa precristiana. Para evitar el sesgo y la hegemonía cultural que vienen implícitos - y así ser mundialmente entendibles y efectivos - le conviene a los conservacionistas de la naturaleza que consideren esta diversidad semántica cuando propongan políticas de conservación e implementen las prácticas de conservación.

Processamento correferencial em idosos com e sem doença de Alzheimer / Coreferential processing in elderly with and without Alzheimer's disease

RESUMO Objetivo Comparar o processamento correferencial, em idosos com e sem a Doença de Alzheimer, no Português Brasileiro. Método Participaram 12 idosos sem Alzheimer (ISA), e 06 idosos com a Doença de Alzheimer (IDA). O Mini-Exame do Estado Mental foi utilizado para triagem cognitiva dos participantes. Dois experimentos foram realizados utilizando a técnica de leitura automonitorada para analisar o processamento da correferência, cada um contendo oito frases experimentais e 24 frases distratoras, um deles utilizou pronomes e nomes repetidos, já o outro utilizou hipônimos e hiperônimos. Após a leitura, foram realizadas perguntas relacionadas ao conteúdo das frases. A principal variável de interesse foi o tempo de leitura aferido após a apresentação das retomadas anafóricas. Resultados No primeiro experimento, foram encontrados resultados estatisticamente significantes, no grupo ISA os pronomes foram processados mais rapidamente do que nomes repetidos, e no grupo IDA, os voluntários foram mais rápidos na retomada do nome repetido. No segundo experimento, os resultados demonstraram que o grupo ISA apresentou preferência, na retomada anafórica, pelos hiperônimos, já o grupo IDA não apresentou diferenças significativas entre as condições. Conclusão Os idosos sem patologia processaram mais rapidamente pronomes e hiperônimos, quando comparados a retomadas com nomes repetidos e hipônimos, respectivamente, pela menor quantidade de traços semânticos necessários para identificar os antecedentes naquelas condições, assim como pela proeminência sintática e discursiva. Nos idosos com DA, os nomes foram lidos mais prontamente que pronomes, e não houve diferença no processamento anafórico envolvendo hipônimos e hiperônimos, podendo decorrer do comprometimento na memória de trabalho.

ABSTRACT Purpose To compare coreferential processing in elderly people with and without Alzheimer's disease in Brazilian Portuguese. Methods Twelve elderly people without Alzheimer's (EA) and six elderly people with Alzheimer's disease (EWA) participated in the study. The Mini-Mental State Examination was used for cognitive screening of participants. Two experiments were performed using the self-monitored reading technique to analyze coreference processing. Each contained eight experimental phrases and 24 distracting phrases, one of them using repeated pronouns and names and the other using hyponyms and hypernyms. After reading, questions were asked related to the content of the sentences. The main variable of interest was reading time, measured after the presentation of anaphoric resuming. Results In the first experiment, there were statistically significant results. The EA group processed the pronouns more quickly than repeated names. The volunteers of the EWA group were quicker in resuming repeated names. In the second experiment, the results show that the EA group showed preference for hypernyms in anaphoric resumption, whereas the EWA group did not present significant differences between conditions. Conclusion Elderly people without pathology processed pronouns and hypernyms more quickly compared to retrievals with repeated names and hyponyms, respectively, due to the smaller amount of semantic traits necessary to identify the antecedents in those conditions, as well as syntactic and discursive prominence. Elderly people with AD read names more readily than pronouns. There was no difference in anaphoric processing involving hyponyms and hypernyms, which may result from impaired working memory.
