ABSTRACT

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.

ABSTRACT

ObjectiveTo effectively organize the interdisciplinary knowledge of traditional Chinese medicine (TCM) and evidence-based medicine contained in the clinical trial literature of TCM and facilitate the processing and mapping of multi-source data, this paper organized the knowledge of clinical trial literature of TCM by ontology modeling. MethodThe seven-step method and skeleton method were used to develop the ontology. After the structure and language characteristics of TCM clinical trial literature were analyzed, the ontological and non-ontological resources such as top-level framework of Scientific Evidence and Provenance Information Ontology (SEPIO) and TCM language system (TCMLS) were reused to determine the domain concepts and attribute relationship. Finally, the core concepts and attribute relationship such as disease, syndrome, symptom, grouping, intervention measures, outcome indicators and literature quality information were determined. ResultThe information contained in the clinical trial literature of TCM was divided into five categories. According to the Cochrane risk of bias assessment tool and CONSORT 2010 statement, the literature quality evaluation information was mapped to the ontology, and a total of 68 categories, 8 object attributes, and 38 data attributes were established, which basically realized the structured expression of clinical trial literature. ConclusionThe ontology of TCM clinical trial literature constructed in this study can well organize, utilize, and present the construction and association of internal knowledge system in TCM clinical trial literature, underpinning the reasoning of strength of evidence and information of diagnosis and treatment in the future.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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'.

ABSTRACT

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.

ABSTRACT

Resumo Este artigo analisa categorias operadas por burocratas ao classificar tipos de usuários e seus efeitos em distribuição de serviços, observando contextos de alta desigualdade e políticas universais. Para tanto, analisa de que modo professores, como burocratas de nível de rua, implementam a política categorizando diferentes tipos de alunos. Adotamos aqui a lente analítica de esquemas culturais, que considera que indivíduos internalizam associações entre categorias oficiais e sociais (informais). Os dados analisados foram coletados de vinhetas aplicadas com 40 professores da rede municipal de São Paulo. Investigamos o uso de categorias por meio de redes sociossemânticas e semânticas de categorizações e construção de cadeias de encaminhamentos. Os resultados apontam que os professores mobilizam de forma concomitante categorias oficiais e sociais, bem como que a introdução da variável "vulnerabilidade" nos casos abre espaço para introdução de categorias sociais que geram diferentes tipos de tratamento para alunos com comportamentos similares.


Resumen Este artículo analiza las categorías operadas por los burócratas al clasificar los tipos de usuarios y sus efectos en la distribución de servicios, observando contextos de alta desigualdad y políticas universales. Para ello, analiza cómo los docentes, como burócratas a nivel de calle, implementan la política categorizando diferentes tipos de estudiantes. Adoptamos aquí la lente analítica de los esquemas culturales, que considera que los individuos internalizan las asociaciones entre categorías oficiales y sociales (informales) a partir de sus experiencias. Los datos analizados se recolectaron a través de viñetas aplicadas a 40 docentes de la red municipal de São Paulo. Analizamos el uso de categorías a través de redes sociosemánticas y semánticas de categorización y construcción de redes de referencia. Los resultados muestran que los docentes movilizan simultáneamente categorías políticas y sociales y que la introducción de la variable "vulnerabilidad" en los casos abre espacio para la introducción de categorías sociales que generan diferentes tipos de tratamiento para estudiantes con comportamientos similares.


Abstract This article analyzes categories operated by bureaucrats when classifying types of users and their effects on the distribution of services, observing contexts of high inequality and universal policies. We analyze how teachers, as street-level bureaucrats, implement the policy by categorizing different types of students. We adopt an analytical lens of cultural schemes, which considers that individuals internalize associations between official and social (informal) categories from their experiences. The analyzed data were collected through vignettes applied to 40 teachers from the municipal education system of São Paulo, Brazil. We analyzed the use of categories through socio-semantic and semantic networks of categorizations and the construction of referral networks. The results show that teachers simultaneously mobilize political and social categories and that the introduction of the variable vulnerability in cases opens space for the introduction of social categories that generate different types of treatment for students with similar behaviors.

ABSTRACT

Objective:To explore the developmental characteristics of Chinese semantic and orthographic processing in normal school-age children by event-related potential (ERP) technique.Methods:Children aged 7-11 in an ordinary primary school in Changzhou were randomly selected and divided into 7-year old group ( n=21 ), 8-year old group ( n=21), 9-year old group ( n=19), 10-year old group ( n=20) and 11- year old group ( n=22) according to their age.ERP was recorded while subjects completed the Chinese character semantic activation task and pseudo word judgment task. Then the N400 and P200 amplitudes of school-age children under the conditions of semantic correlation, semantic uncorrelation and pseudo word judgment were collected, and the data were analyzed by three factors mixed design ANOVA.Data of behavioral accuracy and response time were analyzed by one-way ANOVA and Bonferroni correction was used for multiple hypothesis testing. The statistical software was SPSS 25.0. Results:(1)Behavioral results: the accuracy of semantic related and semantic unrelated tasks of children in the five groups aged 7, 8, 9, 10 and 11 were statistically significant ( F=15.55, 4.01, both P<0.01), and the accuracy of children in the 7-year old group was significantly lower than those in the other four groups (all P<0.05). There was no significant difference in the accuracy of pseudo word judgment task among the five groups ( F=0.68, P=0.609). The response time of children in the five groups under semantic related and semantic unrelated tasks was significantly different ( F=3.90, 3.13, both P<0.05). The response time of the 11-year old group under semantic related tasks was significantly shorter than those of the 7-, 8- and 9-year old groups (all P<0.05). The response time of the 7-year old and 11-year old groups under semantic unrelated tasks was significantly shorter than those of the 8-, 9- and 10-year old groups (all P<0.05). (2)ERP results: N400 amplitudes of 7-, 8-, 9-, 10- and 11-year old children under semantic related tasks were significantly smaller than those under semantic unrelated tasks and pseudo word judgment tasks (all P<0.05). The N400 amplitude of the subjects gradually decreased with the increase of age, except that there was no statistical difference between the 10-year old and 11-year old groups under the semantic related task, between the 8-year old and 9-year old groups under the semantic unrelated task and the pseudo word judgment task, and between the 10-year old and 11-year old groups (all P>0.05), there were statistical differences between the other age groups (all P<0.05). P200 amplitude of semantic related task at 7-, 8-, 9- and 10-year old was significantly higher than that at semantic unrelated task (all P<0.05), and the amplitude of semantic related task at 7-, 8-, 10- and 11-year old was significantly higher than that at pseudo word judgment (all P<0.05). The amplitude of P200 gradually increased with age, and there were significant differences in pairwise comparison among other age groups ( P<0.05), except semantic related task and unrelated task among 7-, 8- and 9-year old groups, between 10- and 11-year old groups, and pseudo word task between 7- and 8- years old groups, 10- and 11- year old groups (all P>0.05). Conclusion:The semantic processing and orthographic processing of school-age children develop with age in a unique way. The age of 7 is an important period for cognitive development of Chinese language.The age of 8-9 may be a sensitive period for the development of brain plasticity, and the development slows down at the age of 10-11.

ABSTRACT

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.

ABSTRACT

ABSTRACT Depressive symptoms are associated with a decline of episodic memory, but the relationship with semantic memory remains unclear. Objective: The aim of the study was to analyze the relationship of depressive symptoms with the semantic memory in a community-based sample of elderly adults. The sample comprised two groups, namely, clinical (with depressive symptoms) and control. Methods: The following instruments were used General Evaluation Questionnaire, Montreal Cognitive Assessment-Basic, Wechsler Abbreviate Scale of Intelligence, Geriatric Depression Scale-30 (GDS-30), Beck Depression Inventory-II, Boston Nomination Test (BNT), vocabulary, verbal fluency test (fruits and animals), and Brief Cognitive Screening Battery. Results: The results showed a significant difference between groups only in BNT. A significant correlation was observed between the BNT and GDS-30. Participants with symptoms of severe depression performed poorly on BNT when compared with individuals with mild symptoms. Conclusion: These results support the hypothesis that depressive symptoms in elderly adults can affect semantic memory and may worsen with the severity of symptoms.


RESUMO Sintomas depressivos estão associados ao declínio da memória episódica, mas sua relação com a memória semântica permanece obscura. Objetivo: O objetivo deste estudo foi analisar a relação dos sintomas depressivos à memória semântica em idosos que vivem na comunidade. A amostra foi composta de dois grupos: clínico (com sintomas depressivos) e controle. Método: Foram utilizados os seguintes instrumentos: Questionário de Avaliação Geral, Montreal Cognitive Assessment-Basic (MoCA-B), Wechsler Abbreviate Scale of Intelligence (WASI), Geriatric Depression Scale-30 (GDS-30), Beck Depression Inventory-II (BDI-II), Teste de Nomeação de Boston (TNB), Vocabulário, Fluência Verbal (Frutas e Animais) e Bateria Breve de Rastreio Cognitivo. Resultados: Os resultados evidenciaram diferença significativa entre os grupos apenas no BNT. Foi observada uma correlação significativa entre TNB e GDS-30. Os participantes com sintomas de depressão grave tiveram um desempenho pior no BNT, quando comparados aos indivíduos com sintomas leves. Conclusão: Esses resultados apoiam a hipótese de que os sintomas depressivos em idosos podem afetar a memória semântica e aumentam com a gravidade dos sintomas.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Abstract Work experiences during undergraduate studies can be remarkable in the journey of undergraduate students. The objective of this study was to assess, by analyzing semantic networks, the role of work experiences in the meanings those individuals attribute to professional identity. The sample consisted of 2291 students (60% women) divided into three groups: do not work, work in a field related to their course, work in a field not related to their course. The semantic networks of these groups were composed of words uttered from the professional identity prime. We chose to work with the critical network, obtained from the analysis of the incidence-fidelity indexes of the word pairs. The results evidence that work experiences are related to how undergraduate students attribute meaning to professional identity, in such a way that three different networks were formed for these groups. The network of those who work outside their field was the only one that integrated words with negative content, while the semantic networks of those who do not work and those who work in their field, despite containing words that do not always coincide, present a similar macrostructure. We conclude that work experiences play an important role in the meanings that undergraduate students attribute to professional identity. The study innovates by revealing elements of professional-identity construction, besides allowing for reflections on the effects of work experiences during the college period.

ABSTRACT

Abstract Analogous to the spectacular growth of information-superhighway, The Internet, demands for coherent and economical crawling methods are translucent to shoot up. Consequently, many innovative techniques have been put forth for efficient crawling. Among them the significant one is focused crawlers. The focused crawlers are capable in searching web pages that are suitable for the topics defined in advance. Focused crawlers attract several search engines on the grounds of efficient filtering, reduced memory and time consumption. This paper furnishes a relevance computation based survey on web crawling. A bunch of fifty two focused crawlers from the existing literature survey is categorized to four different classes - classic focused crawler, semantic focused crawler, learning focused crawler and ontology learning focused crawler. The prerequisite and the mastery of each metric with respect to harvest rate, target recall, precision and F1-score are discussed. Future outlooks, shortcomings and strategies are also suggested.

ABSTRACT

As one of the non-invasive imaging techniques, myocardial perfusion imaging provides a basis for the diagnosis of myocardial ischemia in coronary heart disease. Aiming at the bull-eye image in myocardial perfusion imaging, this paper proposed a branching structure, which included multi-layer transposed convolution up-sampling concatenate module and four-channel weighted channels attention module, and the output results of the branch structure were fused with the output results of trunk U-Net, to achieve accurate segmentation of the cardiac ischemia missing degree in myocardial perfusion bull-eye image. The experimental results show that the multi-layer transposed convolution up-sampling concatenate module realizes the fusion of different depth feature maps, and effectively reduces the interference of the severe sparse degree which is similar to the missing degree on the segmentation. Four-channel weighted attention module can further improve the ability to distinguish between the two similar degrees and the ability to learn edge details of the targets, and retain more abundant edge details features. The experimental data came from Tianjin Medical University General Hospital, Tianjin TEDA Hospital, Tianjin First Central Hospital and Third Central Hospital. The Jaccard scores in the self-built dataset was 5.00% higher than that of U-Net. The model presented in this paper is superior to other optimized models based on U-Net, and the subjective evaluation meets the accuracy requirements for clinical diagnosis.

ABSTRACT

Objective:To explore the feasibility of machine vision and deep learning methods in intelligent screening of pieces of Chinese medicine, so as to meet the needs of modern screening of pieces of Chinese medicine and overcome the problems of strong subjectivity and low efficiency in traditional screening based on manual experience. Method:An image set containing 11 125 images for 60 kinds of pieces of Chinese medicine was constructed, and the network architectures for high- and low-frequency feature learning were designed. Specifically, the parallel convolutional network was employed to obtain the low frequency feature and the deep multi-scale convolutional neural network to uncover the high-frequency feature. The semantic network was used to realize the feature learning mode with generalization ability. In this study, Wasserstein distance was introduced into the generative adversarial networks (GANs) to complete the screening of pieces of Chinese medicine, and the conditional parameters were added to the generation and discrimination networks to make the network training more reliable and improve the accuracy of identification. Result:The experiment results showed that when the ratio of training samples to test samples was greater than 6∶4, the identification accuracy of pieces of Chinese medicine was relatively stable. The identification accuracy of images captured in different states and environments by bi-view multi-feature network Wasserstein generative adversarial network (BMFnet-WGAN) reached up to 85.9% on average and the stability was high, demonstrating that BMFnet-WGAN was superior to VGG-Net and AlexNet. Conclusion:The BMFnet-WGAN method enables the revealing of rich and typical characteristics of decoction pieces and the introduced WGAN model and Wasserstein distance make the network training more reliable. The resulting accuracy, robustness, and batch effects in the intelligent screening of pieces of Chinese medicine were good, which has provided the technical support for the sorting and quantitative quality screening of pieces of Chinese medicine.

ABSTRACT

Resumen: Introducción. Como una iniciativa para mejorar la calidad de la atención sanitaria, en la investigación biomédica se ha incrementado la tendencia centrada en el estudio de las disparidades en salud y sexismo. Objetivo. Caracterizar la evidencia científica sobre la disparidad en salud definida como la brecha existente entre la distribución de la salud y el posible sesgo por sexo en el acceso a los servicios médicos. Materiales y métodos. Se hizo una búsqueda simultánea de la literatura científica en la base de datos Medline PubMed de dos descriptores fundamentales: Healthcare disparities y Sexism. Posteriormente, se construyó una red semántica principal y se determinaron algunas subunidades estructurales (comunidades) para el análisis de los patrones de organización de la información. Se utilizó el programa de código abierto Cytoscape para el analisis y la visualización de las redes y el MapEquation, para la detección de comunidades. Asimismo, se desarrolló código ex profeso disponible en un repositorio de acceso público. Resultados. El corpus de la red principal mostró que los términos sobre las enfermedades del corazón fueron los descriptores de condiciones médicas más concurrentes. A partir de las subunidades estructurales, se determinaron los patrones de información relacionada con las políticas públicas, los servicios de salud, los factores sociales determinantes y los factores de riesgo, pero con cierta tendencia a mantenerse indirectamente conectados con los nodos relacionados con condiciones médicas. Conclusiones. La evidencia científica indica que la disparidad por sexo sí importa para la calidad de la atención de muchas enfermedades, especialmente aquellas relacionadas con el sistema circulatorio. Sin embargo, aún se percibe un distanciamiento entre los factores médicos y los sociales que dan lugar a las posibles disparidades por sexo.


Abstract: Introduction: As an initiative to improve the quality of health care, the trend in biomedical research focused on health disparities and sex has increased. Objective: To carry out a characterization of the scientific evidence on health disparity defined as the gap between the distribution of health and the possible gender bias for access to medical services. Materials and methods: We conducted a simultaneous search of two fundamental descriptors in the scientific literature in the Medline PubMed database: healthcare disparities and sexism. Subsequently, a main semantic network was built and some structural subunits (communities) were identified for the analysis of information organization patterns. We used open-source software: Cytoscape to analyze and visualize the semantic network, and MapEquation for community detection, as well as an ad hoc code available in a public access repository. Results: The core network corpus showed that the terms on heart disease were the most common among the descriptors of medical conditions. Patterns of information related to public policies, health services, social determinants, and risk factors were identified from the structural subunits, but with a certain tendency to remain indirectly connected to the nodes of medical conditions. Conclusions: Scientific evidence indicates that gender disparity does matter for the care quality in many diseases, especially those related to the circulatory system. However, there is still a gap between the medical and social factors that give rise to possible disparities by sex.

ABSTRACT

RESUMEN La situación de violencia en Colombia ha producido dinámicas que escapan al control del Estado y dificultan la construcción de la agenda pública de las instituciones estatales, ya que estas poseen limitaciones para describir el entorno social y político que influye en el territorio. Para suplir estas limitaciones, es pertinente generar redes semánticas que describan información sobre las comunidades víctimas del conflicto armado. Lo anterior permitirá generar un insumo que las instituciones y autoridades locales puedan emplear para reconocer pilares en la formación de políticas públicas coherentes a las necesidades de cada comunidad. En el presente artículo, se expone el proceso para la generación semiautomática de una red semántica a partir del tratamiento de datos textuales. Para tal fin, se han empleado herramientas de minería de textos y técnicas de análisis multivariado. La red semántica generada es una primera aproximación para la descripción de las características del caso de estudio de la comunidad de Arauca durante los años 2013-2018.


ABSTRACT The situation of violence in Colombia has produced dynamics that are beyond the control of the State and make it difficult for state institutions to build the public agenda. These institutions have limitations to describe the social and political environment that influence the territory To overcome these limitations, it is pertinent to generate semantic networks that describe information about communities victims of the armed conflict and, thus, generate an input that local institutions and authorities can use to recognize pillars in the formation of public policies consistent with the needs of each community. In this document is presented the process for the semi-automatic generation of a semantic network from the processing of textual data, using text mining tools and multivariate analysis techniques. The semantic network generated is a first approximation for the description of the characteristics of the Arauca community during the years 2013-2018, which was selected as a case study.


RESUMO A situação de violência na Colômbia tem produzido dinâmicas que estão além do controle do Estado e dificultam a construção de uma agenda pública por parte das instituições estatais, já que estas têm limitações na descrição do ambiente social e político que influencia o território. Para superar essas limitações, é pertinente gerar redes semânticas que descrevam as informações sobre as comunidades vítimas do conflito armado. Isto permitirá gerar um input que as instituições e autoridades locais possam utilizar para reconhecer pilares na formação de políticas públicas que sejam consistentes com as necessidades de cada comunidade. Neste artigo, é apresentado o processo para a geração semiautomática de uma rede semântica baseada no processamento de dados textuais. Para isso, foram utilizadas ferramentas de mineração de texto e técnicas de análise multivariada. A rede semântica gerada é uma primeira abordagem para descrever as características do estudo de caso da comunidade Arauca durante os anos 2013-2018.
