El marco visual del candidato político en Instagram: las elecciones autonómicas catalanas de 2021
Social networks are tools for constructing digital identity, making online impression management possible. This
study explains, in the context of the politainment age, the way in which Instagram allows political candidates to build their digital
image; that is, to perform online self-representation. Specifcally, the focus of this paper is the image of political candidates
on Instagram during the campaign of the 2021 Catalan regional elections on February 14. It links Gofman’s (1956) theory of
the presentation of the self in everyday life to both current research approaches to online self-representation and Grabe and
Bucy’s (2009) visual framing theory. The objective is to study the type of elements employed by candidates for constructing
their photographic and video stage settings and, therefore, their digital identities during the election campaign. After an
operationalization of Gofman’s and Grabe and Bucy’s theories resulting in 27 items, a content analysis was carried out on a total
of 215 Instagram posts of the eight main candidates published between 29 January and 13 February 2021. It has been observed
that all political candidates show themselves in a more professional way, and it couldn’t be afrmed that a certain visual frame is
attached to a certain ideology. In line with previous research, our results show that the ‘ideal candidate’ was the predominating
frame, although particularities corresponding to the 2021 Catalan context were observed. Implications to the current context of
online political communication are identifed and discussed.Las redes sociales son herramientas de construcción de la identidad digital que posibilitan la gestión de esta. Este
estudio explica, en el contexto de la era del politainment, el modo en que Instagram permite a los candidatos políticos construir
su imagen digital; es decir, realizar una autorrepresentación online. En concreto, este trabajo se centra en la imagen de los
candidatos políticos en Instagram durante la campaña de las elecciones autonómicas catalanas del 14 de febrero de 2021. Se
relaciona la teoría de Gofman (1956) sobre la presentación del yo en la vida cotidiana con los enfoques de investigación actuales
sobre la autorrepresentación online y la teoría del encuadre visual de Grabe y Bucy (2009). El objetivo es estudiar el tipo de
elementos empleados por los candidatos para construir sus escenarios fotográfcas y videográfcas y, por tanto, sus identidades
digitales durante la campaña electoral. Tras una operacionalización de las teorías de Gofman y Grabe y Bucy que dio como
resultado 27 ítems, se realizó un análisis de contenido de un total de 215 posts de Instagram de los ocho principales candidatos
publicados entre el 29 de enero y el 13 de febrero de 2021. Se ha observado que todos los candidatos políticos se muestran de
una forma más profesional, y no se ha podido afrmar que un determinado marco visual vaya unido a una determinada ideología.
En línea con investigaciones anteriores, nuestros resultados muestran que el “candidato ideal” fue el marco predominante,
aunque se observaron particularidades correspondientes al contexto catalán de 2021. Se identifcan y discuten las implicaciones
para el contexto actual de la comunicación política online
Adquisición de una discriminación condicional bajo diferentes historias de entrenamiento de correspondencia
El entrenamiento de correspondencia es un procedimiento cuyo propósito esfortalecer, desarrollar, eliminar o debilitar cierta conducta mediante la verbalizaciónde lo que se va a hacer o la descripción de lo que se hizo. En el presenteestudio, se modificó una tarea de igualación de la muestra de segundoorden para someter a participantes de dos poblaciones estudiantiles distintasa diferentes historias de entrenamiento de correspondencia decir-hacer, hacer-describir y decir-describir para analizar los efectos de este entrenamientosobre la adquisición y generalidad de la discriminación condicional. El entrenamientode correspondencia interfirió con la adquisición de la igualación yaque los participantes que aprendieron la discriminación condicional lo hicieronbajo la condición de prueba de transferencia. Estos resultados parecensugerir que el establecimiento de correspondencias entre lo que se dice quese va a hacer, lo que se hace y lo que se describe que se hizo puede estarasociado a la intervención funcional de la retroalimentación, es decir, a lamanera en que la retroalimentación favorece que un factor o la relación entredos factores de la tarea de igualación logre aparecer con un peso relativo mayorque los otros elementos de las relaciones contingenciales entrenadas

Ordered Mesoporous Carbon as a Support of Pd Catalysts for CO2 Electrochemical Reduction
© 2020 by the authors.Ordered mesoporous carbons (OMCs) have been used as catalyst supports of Pd nanoparticles for the electrochemical reduction of CO2 in 0.1 M KHCO3. OMC with tunable porosity and morphology were obtained by the hard-template approach using synthesized SBA-15 templates. SBA-15 materials were prepared using a mass ratio of the silica precursor (TEOS) and the surfactant (P123) of 2 or 5. After removing silica particles by a purification treatment with NaOH-ethanol or HF, different OMCs were obtained, with a developed porosity (up to 1050 m2 g−1) and ordered 2D hexagonal mesostructure (p6 mm). An increase in the TEOS/P123 ratio as well as the treatment with HF resulted in a decrease in the structural ordering of the materials. Pd nanoparticles with an average size of around 3 nm were deposited on the OMC. However, larger nanoparticles were also observed, especially for the materials obtained using a mass ratio TEOS/P123 of 5. Despite these differences, electrochemical experiments showed that CO2 was successfully reduced to other species (mainly COad) for all Pd/OMC electrocatalysts. These reduced species were adsorbed on Pd active sites, inhibiting the hydrogen evolution reactionThe authors gratefully acknowledge the financial support given to the Fuel Conversion Group by the Aragón Government (T06).Peer reviewe

Master of Science in Physics Education at the University of Guadalajara: The curricular design process
INTRODUCTION
The need for a postgraduate degree in Physics Education arises from the importance of improving science learning, in particular physics, in students from elementary to high school derived from the analysis of test results such as PISA (OECD, 2019). In addition, training high-level human resources who generate knowledge regarding the teaching-learning process of Physics at any educational level (including undergraduate and postgraduate) is important.
JUSTIFICATION
The problems experienced by contemporary society are complex, their solution and understanding require the articulation of different skills, knowledge, attitudes and values related to science and technology due to the constant progress of these areas. The curricular team, based on this scenario and considering what is stated in the educational model of the University of Guadalajara (Castellanos et al., 2007) about focusing activities on what the student does, decided that the postgraduate training process would be based on the development of skills.
THE CURRICULAR DESIGN PROCESS
For this reason, the work for the curricular design of the Master of Science in Physics Education at the University of Guadalajara was developed through nine phases (Díaz-Barriga, 1990): Formation of a curricular team; Detection of Physics Education needs; Identification of potential demand; Detection of similar programs; Delimitation of the graduate's field of action; Definition of competencies; Identification of knowledge necessary for the professional performance of the graduate; Definition of Learning Units and curriculum plan; Determination of an evaluation plan for the program (internal and external). In this work, the generalities related to the curricular design process of the Master of Science in Physics Education program at the University of Guadalajara are presented. From this process we have obtained a proposal of the program, now we are waiting for the suggestions and approval by the highest government authority at our University, Consejo General Universitario (the creation project can be viewed here).

El Efecto De La Implantación Temprana En Niños Con Hipoacusia
Hearing loss in pediatric population is a major health concern, taking into account the immediate repercussions on the cognitive, emotional and language development (serious difficulties in communication and language development). Therefore, it is of crucial importance its early diagnosis and implantation. The objective of this study is to know the effect of cochlear implant on the development of oral language in implanted children in the Province of Santa Cruz de Tenerife (Canary Islands). In order to carry out this research, the psycholinguistic profiles of children who were implanted between 2011 and 2014 were studied, through the use of two standardized tests, Peabody Picture Vocabulary Test and The Illinois Test of Psycholinguistic Abilities (ITPA). As regards the age of implantation, we could observe a significant tendency to use the visual channel in the communication of those children who were implanted at a later age and a tendency to use the auditory channel at an early age of implantation. Children who were implanted at a later age showed a nonfunctional use of the implant and a limited development of their speaking skills
Autoimmune vitiligo in rheumatic disease in the mestizo Mexican population
Vitiligo is a chronic disease characterized
by the dysfunction or destruction of melanocytes with
secondary depigmentation. The aim of the present study
was to determine the prevalence of vitiligo associated with
autoimmune rheumatic diseases. The clinical records from
a 10-year database of patients with rheumatic diseases
and associated vitiligo was analysed, with one group of
patients having autoimmune rheumatic disease and another
non-autoimmune rheumatic disease. Available serum samples
were used to assess the anti-melanocyte antibodies. A total
of 5,251 individual clinical files were archived in the last
10 years, and these patients underwent multiple rheumatology
consultations, with 0.3% of the group presenting with vitiligo.
The prevalence of vitiligo in the autoimmune rheumatic
disease group was 0.672%, which was mainly associated with
lupus and arthritis. However, patients with more than one
autoimmune disease had an increased relative risk to develop
vitiligo, and anti-melanocyte antibodies were positive in 92%
of these patients. By contrast, the prevalence was 0.082% in
the group that lacked autoimmune rheumatic disease and
had negative autoantibodies. In conclusion, the association
between vitiligo and autoimmune rheumatic diseases was
relatively low. However, the relative risk increased when there
were other autoimmune comorbidities, such as thyroiditis or
celiac disease. Therefore, the presence of multiple autoimmune
syndromes should be suspected
Análise do discurso didático empregando uma tarefa de igualação da amostra da segunda ordem
Learning to teach seems to be a product of direct experiential learning. Therefore, in this study, a second-order matching-to-sample task was used to evaluate the didactic discourse that a person can elaborate from his own learning. The research design involved two different phases, learning and teaching. During the learning phase, the participants were trained in the matching task with a procedure that gradually increased its complexity .During the teaching phase, each trained participant had to teach another two participants on how to perform effectively in similar tasks. Results were analyzed in terms of the trained participants performance on the task, transference of learning, processes involved in the elaboration of didactic discourse, and the effects of teaching on he apprentices. Data suggest that all participants learned the matching task, either by direct training or by being exposed to didactic discourse. However, differences on performance during transfer tests were found among participants due to the different ways of verbalizing task criteria and effective performance involved in didactic discourse.Aprender a enseñar parece ser resultado de un aprendizaje vivencial y directo. Por ello, en el presente estudio, se utilizó una tarea de igualación de la muestra de segundo orden para evaluar la construcción de un discurso didáctico a partir del propio aprendizaje. El diseño experimental consideró dos momentos, uno de aprendizaje y otro de enseñanza. En el primero, se entrenó la tarea de igualación con un procedimiento de complejidad creciente. En el segundo, cada participante entrenado tuvo que enseñar a otros dos cómo contestar tareas similares a las que se sometieron. Los resultados se analizaron en términos del dominio de la tarea por los participantes expuestos al entrenamiento de aprendizaje, las posibilidades de transferencia de lo aprendido, los procesos implicados en la elaboración de un discurso didáctico, y los efectos del acto de enseñar sobre los aprendices. Todos los sujetos aprendieron la igualación, ya sea por entrenamiento directo o mediante la exposición al discurso didáctico. Sin embargo, hubo diferencias en el desempeño durante las pruebas de transferencia debido a las distintas formas de verbalizar los criterios de ejecución correcta implicados en el discurso didáctico.Aprender a ensinar parece o resultado de uma aprendizagem vivencial e direito. Portanto, neste estudo, utilizou-se uma tarefa de igualação da amostra de segunda ordem para avaliar a construção de um discurso didático a partir da aprendizagem própria. O desenho experimental considerou dois momentos. No primeiro, treinou-se a tarefa de igualação com um procedimento de complexidade crescente. No segundo, cada participante treinado tive que ensinar a outros dois como responder a tarefas semelhantes às que foram submetidos. Os resultados se analisaram em relação ao domínio da tarefa pelos participantes expostos ao treinamento de aprendizagem, as possibilidades de transferência do aprendido, os processos envolvidos na elaboração de um discurso didático e os efeitos que ato de ensinar produze nos aprendizes. Todos os sujeitos aprenderam a igualação, bem seja por treinamento direito ou através da exposição ao discurso didático. No entanto, apresentaram-se diferenças no desempenho durante as provas de transferência, devido as diferentes formas de verbalizar os critérios de execução correta envolvidos no discurso didático
Índices demográficos sintéticos a nivel local: un acercamiento a la relación población-desarrollo
The indexes suggested in this paper are local demographic behavior and specific local demographic behavior; the latter was adapted from the former. Their determination is a step in advance within the population-development relationship. Its single value allows for observation of behaviors of demographic and population aging variables, and their effects on municipal development. Index calculation and computer tools like MAPINFO were used for statistical analysis. The aim of this paper is to design synthetic indexes capable of providing information to local governments for decision-making to set up development strategies. The novelty of this research is that no previous national or international reports have been issued about this topic.En este trabajo se proponen los índices: del comportamiento demográfico local y del comportamiento demográfico local específico, este último una adaptación del primero. La determinación de ambos constituye un paso de avance en la interrelación población-desarrollo, en tanto permite, a través de un solo valor, observar el comportamiento, tanto de las variables demográficas como del envejecimiento de la población y su incidencia en el desarrollo de los municipios de una provincia o de un municipio en específico. Se utilizó el método estadístico para el cálculo de los índices; así como herramientas informáticas tales como el MAPINFO. El trabajo tiene como objetivo diseñar índices sintéticos que brinden, desde el punto de vista demográfico, información a los gobiernos locales para la toma de decisiones en la elaboración de la estrategia de desarrollo. Cabe resaltar que estos resultados no tienen antecedentes nacionales ni internacionales, de ahí su novedad científica
