Thirty-two semen samples from four rams were frozed using two antioxidants, Tempo (2,2,6,6 tetramethyl-1-piperidinyloxyl) and Tempol (4-hidroxi 2,2,6,6 tetramethyl-1- piperidinyloxyl), each one in concentrations of 0.5, 1.0, and 2.5 mM, to evaluate the effects on post-thawing motility, viability, acrosomal integrity, and earlier sperm capacitation. Eight replications for each antioxidant concentration and control group, were done using four semen samples per replication. Semen samples were diluted on a Tris extender. Results showed that Tempo 0.5 mM improved frozen semen quality in comparison with control group (p<0.05), by increasing progresive motility (79 vs. 67%), viability and acrosomal integrity (70 vs. 58%), and decreasing earlier sperm capacitation (9 vs. 15%). On the other hand, Tempol decreased frozen semen quality. In conclusion, the use of Tempo 0.5 mM on a Tris extender, ...

Se emplearon 32 muestras de semen procedentes de cuatro ovinos a fin de ser criopreservadas con la adición dos antioxidantes: Tempo (2,2,6,6 tetrametil-1-piperidiniloxil) y Tempol (4-hidroxi 2,2,6,6 tetrametil-1-piperidiniloxil), en concentraciones de 0.5, 1.0 y 2.5 mM, para evaluar el efecto postdescongelamiento que pudieran tener sobre la motilidad progresiva, la viabilidad e integridad acrosomal y la capacitación espermática prematura. En cada concentración de los dos antioxidantes y del grupo control se utilizó un dilutor en base a Tris, realizándose ocho repeticiones, cada una con cuatro muestras de semen. Los resultados obtenidos demuestran que la adición de Tempo a una concentración de 0.5 mM mejora significativamente la calidad del semen criopreservado en comparación con el grupo control (p<0.05), incrementado los porcentajes de motilidad progresiva (79 vs. 67%), viab...

Introduction: The variations of the intentional monitoring carried out by university students on attributes and temporalities of complex learning are analyzed. Objective: to identify the structural relationships between affective and cognitive attributes considered at different times of performance in two tasks of academic skills. Method: intentional sample of 420 students of Higher Education of Mexico and Colombia, of both sexes, answered: a) an inventory of the self-report on variations in attributes and temporal moments in two different tasks and b) two tests, one of comprehension of texts and another of mathematical skills. The theoretical models underlying the assumed academic performance were validated, empirically, through path analysis. Results: high rates of practical fit in all models, which allows identifying differential influences depending on the temporal condition in which...

El término “timing” es comúnmente utilizado en la formación actoral y el trabajo escénico; no obstante, su concepto no ha sido sistematizado bajo la denominación mencionada. Por ende, no se explica a los actores y actrices cómo llegar a obtenerlo. Por lo tanto, con esta investigación, se propone un concepto de timing y se busca sistematizar un entrenamiento del mismo, mediante el género musical jazz y lo propuesto por Jacques Lecoq en la máscara neutra. De esta manera, será necesario analizar el jazz como estímulo para el principio de ritmo trabajado en el uso de la máscara neutra como herramienta de entrenamiento para el timing actoral. Además, se contará con otras investigaciones que aportan al ámbito musical y al actoral. Entre las fuentes principales de este trabajo, resaltan Jacques Lecoq, quien expone su pedagogía con la máscara neutra; Henkjan Honing, que prof...

Introduction: The COVID-19 pandemic modified all aspects of life including the educational field, where higher education institutions implemented classes through digital platforms, in all areas of knowledge, including Law. Objective: To describe the assessment of law students regarding the virtual teaching-learning process and teaching innovation in the context of the COVID-19 pandemic in a higher education institution in northern Chile. Method: A questionnaire was applied to evaluate the participants’ evaluation of the e-learning and teaching innovation process in the context of the COVID-19 pandemic. Descriptive analyses and differences in proportions were performed. Results: The evaluation of the teaching-learning process was mostly regular. On the other hand, among the advantages, the organization of time and the possibility of visualizing the class recordings were highlighted. Con...

In the current socio-political situation in Colombia and in the post-agreement scenario (2016), in coexistence with the internal armed conflict, the relationship between memory and space is reflected; it is formulated from its communicative and political character, taking into account, as a starting point, that memory is a social construction, anchored in space-time in the daily life of communities, formulated as a subjective interaction, which, when socialized, becomes collectivized; that is, it has an intersubjective nature, managing dialogic and social networks, updating ways of knowing reality and influencing the transformations of communities. The objective is to formulate a reflection on the socio-discursive and political-cultural construction of memory, to address space-time in a place of memory in Bogotá; relationship that is characterized by having a communicative, symbo...

In the face of the COVID-19 pandemic, economies are shutting down and paralyzed, and societies are facing rigid health measures such as social isolation, with its own effects, e.g., the suspension of face-to-face classes (which is a necessary protective measure for all students and teachers). We are living in uncertain times and we do not have an answer for everything, but the acceleration of virtualization is evident. This phenomenon has made it possible to sustain personal communications, entertainment activities at home and, in education, infodemia is expanding, with a heterogeneity of information through virtual and technological resources available for the teaching-learning process; however, unequal access has revealed the deep inequality that exists among students (Gallo, 2020), with a high digital gap between the richest and poorest quintiles.

The education of programming has between its main objectives, the development and the formation of skills on the part of the students, who make possible the resolution of problems of the school, professional or of the practical life taking into account the different resources that offer the languages of programming. In the training course of computer teachers, this process has some characteristics that distinguish it. The teachers to be must develop the skill and at the same time to appropriate of the necessary procedures to direct this process in the school. This article presents the main results obtained regarding this topic during the teaching learning process of several subjects of Programming in the training of Informatics teachers, with the systematization of living experiences, during nine years.

The main aim of this exploratory and pre-experimental study is to establish the variations in the distribution of visual attention of translators in training during a reading task with Specialized Extensive Nominal Phrases (hereinafter SNEE). To achieve this goal, a case study was conducted with four translators in training who had to read 10 contexts of a Human Genome corpus that contains SNEE of three and five tokens. Data collection was performed through the eye movement technique and a Likert scale-type questionnaire. The results of this study showed that the distribution of the visual attention of the translators in training presented variations according to the length of the SNEE. Longer time and number of fixations were observed in the SNEE of five tokens in contrast to the SNEE of three tokens. Likewise, the length variable is a factor that affects visual attention during the p...

This article presents an experience carried out by the faculty of the third year of the Infant Education degree at the Ramon Llull University in Barcelona (Spain). A proposal for multidisciplinary intervention that joins two modules: one for arts (musical, corporal, visual, and plastic education) and another for sciences (mathematics, and experimental and social sciences). The intervention stems from a generating idea—the book “Alice in Wonderland”—which allows for connections between the contents of the modules, involves co-teaching, multidisciplinary work, and shared evaluation experiences. The aim of the study is to get to know the perception of the participating faculty about the changes in the didactic components involved in the experience. For data collection, semi-structured interviews were carried out at three moments of the process and a discussion group at the end. The ...
