Rethinking Multimodal Literacy in Theory and Practice
No full textThe wide range of scholarly works in fields of enquiry such as film and media studies, cultural studies, linguistics, and education demonstrates the exponentially expanding interest in multimodality over the past two decades (see, e.g., Bateman & Schmidt, 2012; Djonov & Zhao, 2014; Kress et al., 2014). The creation of a new SAGE journal, Multimodality & Society, whose first issue was published in 2021, testifies to the growing body of literature on multimodality. Multimodal methodologies, based on Gunther Kress’s idea that “language, whether as speech or as writing, is one as many available for representation and for making meaning” (2012, p. 37), have gained in popularity, showing beyond doubt the relevance of different theoretical perspectives and their practical application in the classroom. Unlike traditional studies in foreign language teaching, which focus mainly on language, in multimodal approaches language is just one of the multiple modes for meaning-making and communication. Although studies show that “multimodal resources integrate naturally to facilitate language teaching and learning in an orderly, structured and goal-oriented manner in classroom lessons” (Tan et al., 2016, p. 253), the multimodal turn reveals the need to integrate the development of multiliteracies in our understanding of effective communication. The changing nature of learning environments, which involve rapidly evolving digital practices and media affordances, renders certain conventional approaches obsolete and requires greater flexibility and faster adaptability of the teaching process to the new multi-semiotic and multisensory virtual learning environments
Factors affecting the frequency of citation of an article
Get PDFThe relevance of citations is clear since they constitute a substantial part of most bibliometric indicators. The aims of the present paper are to identify several factors associated with obtaining citations to explain these and, finally, to offer authors a number of useful suggestions. Those studies that have had the greatest influence on science are also those that are most frequently cited. The essential factor leading to a study being cited is that it should make a significant contribution to the advance of science; that is, the relevance of the research. But other essential dimensions exist: Accessibility; Dissemination; Scientific authority. Other predictive factors allow us to predict the number of citations a document may receive: Prior production by the authors; Structural context of the work; Scientific trends; Validity/Obsolescence (expiry) of results; Quality of formal aspects; Theoretical context of the study; Types of work. Finally, some ways are suggested to improve the citations of their works and thus contribute to a wider dissemination and development of science
Emotional management in teachers, an analysis from experience
Get PDFThis research article analyses the emotional management of 46 teachers in the department of Boyacá (Colombia) according to their level of professional teaching experience, from the theoretical perspective of Mayer and Salovey’s emotional skills. It uses a descriptive- comparative process with different perspectives across three stages: quantitative, qualitative and mixed. It also utilizes the MSCEIT emotional intelligence questionnaire, a semi-structured interview, and an observational analysis. The results show competent development of teachers’ emotional skills, but with statistically significant differences in emotional management by experience. The teachers also mention in their narratives that the emotional management that occurs in school interactions and in the educational process has two facets: difficulties and positive emotional management. Similarly, the gestures that are part of non-verbal emotional communication that supports this skill are established. Therefore, it is concluded that emotional management as a skill decreases as experience increases, given that emotional experiences in the classroom generate stress, emotional exhaustion, and even leaving the profession.Este artículo de investigación analiza el manejo emocional según la experiencia profesional docente de 46 maestros del departamento de Boyacá (Colombia), desde la perspectiva teórica de las habilidades emocionales de Mayer y Salovey. Para ello, se ha utilizado un proceso descriptivo-comparativo que integra distintas perspectivas en tres momentos: cuantitativo, cualitativo y mixto. También se ha hecho uso del cuestionario de inteligencia emocional MSCEIT, una entrevista semiestructurada y un análisis observacional. Los resultados demuestran que existe un desarrollo competente de las habilidades emocionales de los maestros, pero se encuentran diferencias estadísticamente significativas con respecto al manejo emocional en función de la experiencia. Además, los participantes mencionan en sus narrativas que el manejo emocional que ocurre en las interacciones escolares y en el proceso educativo tiene dos facetas: las dificultades y el manejo emocional positivo. De igual manera, se establecen los gestos que intervienen en la comunicación emocional no verbal que sustenta esta habilidad. De todo ello, se concluye que, con el aumento de la experiencia, disminuye la habilidad para el manejo emocional, dado que las experiencias emocionales en las aulas generan estrés, agotamiento emocional e, incluso, abandono de la profesión
Improving the Dynamic Performance of Bridgeless PFC Controllers with Zero Crossing Detector and Root-Mean-Square Calculation Blocks
No full textBridgeless Power Factor Correctors (PFC) with a controller utilizing rectified ac variables can benefit from well-established strategies and circuits employed in PFCs with diode-bridge front-end. The grid voltage polarity is detected to compute the rms value of the grid voltage, and also used to generate and route the gate signals for the power devices. However, depending on the implementation, grid voltage disturbances may propagate through the polarity detection and RMS calculation stages, leading to a degradation of the input current and output voltage. This issue is addressed in this manuscript by investigating a single-phase bridgeless totem-pole (TP) PFC through simulation and proposing the replacement of the conventional implementation with a frequency-locked loop (FLL) to enhance the converter dynamics
Loneliness, Pornography Use, Problematic Pornography Use, and Compulsive Sexual Behavior
No full textPurpose of review: Loneliness is a subjective experience characterized by distressing feelings resulting from a discrepancy between desired/expected and actual levels of social interactions. This narrative review explores the literature on relationships between loneliness, pornography use (PU), problematic pornography use (PPU), and compulsive sexual behavior disorder (CSBD), including bidirectional natures of these relationships. Recent findings: Relationships between PU/PPU and loneliness have been explored from different perspectives. Studies have found a positive association between PU/PPU and loneliness, with loneliness increasing as severity of PPU rises. PU/PPU have also been identified as potential predictors of loneliness, with individuals engaging in PU/PPU more likely to experience loneliness. Loneliness may also predict PU/PPU, with individuals experiencing higher levels of loneliness being more prone to use pornography as a maladaptive coping strategy (although this relationship is not clear in longitudinal studies). Regarding CSBD, individuals with versus without CSBD have been found to exhibit higher levels of loneliness, although these findings have not been consistently replicated. Summary: This review provides insights into complex relationships between loneliness, PU/PPU, and CSBD, highlighting a need for further research to understand underlying mechanisms and develop effective interventions
Virtual Reality in E-commerce: Brief Review of Current State
No full textSocial media and existing platforms on the Internet are resources that have improved the level of exposure of brands, products, and services; small and large companies have used these resources to the point of becoming monotonous over the years at the time of entering the digital market. This inconvenience, added to the excessive number of social profiles, the mismanagement of these platforms and the great technological advancement forces different companies to use new alternatives to innovate the process of buying and selling products or services. Virtual reality (VR) has become the tool to be used to grant a unique experience at the moment of interaction between consumers and suppliers. In this sense, this work proposes a review of the current state of the inclusion of VR in e-commerce, it has been identified that virtual reality is a resource that allows a close approximation to reality in which users have the possibility of having a unique experience with a product or service in a fast, modern, and safe way
Well-being of Older Adults in Continuing Education: Age and Gender Exploration
Get PDFThis pilot study, a precursor to more in-depth research, examines the relationship between age, gender, and well-being in older adults participating in educational programs. Employing a quantitative design, descriptive analyses, T-Tests, ANOVA, and correlations were used to assess participants' responses. The results highlight an imbalanced age and gender distribution, with a predominance of individuals aged 66–75 and a higher proportion of women. The analyses reveal significant differences in well-being based on gender and age. Correlations indicate that as age increases, so does satisfaction with past and future life, although interest in new challenging experiences decreases. This study underscores the importance of considering demographic differences when designing and implementing educational programs for older adults, emphasizing the need for specific adaptations to maximize well-being and participation
Relación entre control inhibitorio y rendimiento académico en estudiantes entre 15 y 17 años
Get PDFThere is great interest on the part of the educational community in improving student learning and
reducing school failure; likewise, to understand brain functioning and its relationship with
educational variables. The executive functions (FE), including inhibitory control (CI), are an
important part of human cognitive development, therefore, the study of its components in the
educational area is valuable, especially in adolescents, which has been little studied the relationship
between IC and academic performance (RA).
This Master's thesis proposes a research project whose objective is to determine the relationship
between CI and RA, specifically with the subjects of mathematics, language, natural and social
sciences, in a group of 35 students between 15 and 17 years of eleventh grade in the Colombian
context.
For this purpose, a study is proposed with a non-experimental quantitative approach, with a
descriptive correlational and cross-sectional design. The measurement of CI is projected through
the Stroop: colors and words test and the RA through the cumulative average of grades for each
subject in the academic bulletin. It is expected to observe a direct and statistically significant
relationship between CI and RA in the basic subjects evaluated at the school level, which are also
those subjects analyzed in the “SABER 11” state exam. In this way, the results obtained would
facilitate the design of CI training programs, as well as appropriate teaching methodologies and
strategies that contribute to learning and improvement in adolescents´ RA.Existe gran interés por parte de la comunidad educativa en mejorar el aprendizaje de los estudiantes
y reducir el fracaso escolar, así mismo por comprender el funcionamiento cerebral y su relación con
variables educativas. Las funciones ejecutivas (FE), incluido el control inhibitorio (CI), son parte
importante en el desarrollo cognitivo del ser humano, por ende, resulta valioso el estudio de sus
componentes en el área educativa, especialmente en adolescentes, donde es poco estudiado la
relación del CI con el rendimiento académico (RA).
El presente Trabajo de Fin de Máster plantea un proyecto de investigación cuyo objetivo es
determinar la relación entre el CI y el RA, específicamente con el área de matemáticas, lenguaje,
ciencias naturales y sociales, en un grupo de 35 estudiantes entre 15 y 17 años de grado undécimo
en el contexto colombiano.
Para tal fin, se plantea un estudio con enfoque cuantitativo no experimental, de diseño descriptivo
correlacional y corte transversal. La medición del CI se realiza mediante el Stroop: Test de Colores y
Palabras y el RA a través del promedio acumulado de calificaciones de cada materia en el boletín
académico. Se espera observar una relación directa y estadísticamente significativa entre el CI y el
RA en las asignaturas básicas evaluadas a nivel escolar, que además son las que se analizan en el
examen de estado “SABER 11”. De este modo, los resultados obtenidos facilitarían el diseño de
programas de entrenamiento del CI, así como metodologías y estrategias de enseñanza oportunas
que contribuyan al aprendizaje y a la mejora en el RA de los adolescentes
La mirada aguda de Ramón Irigoyen a la España del cambio de siglo en los ‘Romances satíricos’ (2011)
Get PDFLos Romances satíricos1 de Ramón Irigoyen se basan en acontecimientos y personas de los años
comprendidos entre 1995 y 2004 y fueron difundidos en el programa «Al sur de la semana» de la cadena COPE, los primeros, y en la revista humorís- tica El virus mutante los segundos, lo cual condiciona la necesidad de ajustar su com- prensión a la relativa perentoriedad de hechos muy concretos, fácilmente identificables por los lectores nacidos no más tarde de los años ochenta2. Este tratamiento es ple- namente coherente con el hecho de que Jiménez Millán, siguiendo la terminología de Castellet, ya considerase a Irigoyen, muchos años antes de la publicación de este poemario, como un ejemplo de la «razón narrativa» que caracteriza a los poetas
La estafa piramidal en el ámbito de las organizaciones criminales: cuestiones entorno a una posible necesidad de reforma legislativa
Get PDFThe successive legislative reforms of our penal code make it necessary to review the
crime of fraud and all its elements, to see what the existing legal landscape is, its evolution
and its current level of protection.
Obviously, this must be put in the context of the current criminal reality, to see what
is the dynamics of criminal organizations in the field of fraud crime, the incidence of new
technologies, and transnationalization. Especially the pyramid scam model whose
consequences sometimes become ruinous and socio-economic transcendental.
This will allow us to delve into the most important modalities of the crime of fraud,
analyse them legally from the factual perspective, the legal response offered by our legal
system, and especially from the field of comparative law, observing the example of countries
that have legislated in this regard.
Finally, on the basis of the reasoning set out above, make the proposals of lege ferenda
that are considered necessary to face it.Las sucesivas reformas legislativas de nuestro código penal hacen necesario revisar el
delito de estafa y todos sus elementos, para ver cuál es el panorama jurídico existente, su
evolución y su nivel de protección actual.
Evidentemente ello debe ponerse en contexto de la realidad delincuencial actual, ver
cuál es la dinámica de las organizaciones criminales en el ámbito del delito de estafa, la
incidencia de las nuevas tecnologías, y la transnacionalización. Especialmente las modalidades
de estafa piramidal cuyas consecuencias en ocasiones llegan a ser ruinosas y de trascendencia
socio-económica.
Ello nos permitirá adentrarnos en las modalidades más trascendentes del delito de
estafa, analizarlas jurídicamente des de la perspectiva fáctica, la respuesta jurídica que ofrece
nuestro ordenamiento jurídico, y especialmente desde el ámbito del derecho comparado,
observando el ejemplo de países que han legislado en este sentido.
Finalmente, en base a los razonamientos expuestos hacer las propuestas de lege
ferenda que se consideran necesarias para afrontarl
