Given the environmental problems humanity is currently facing, and considering that the future of the planet lies in the hands of children and their actions, research on the determinants of sustainable behaviors in children has become more relevant; nonetheless, studies on this topic focusing on children are scarce. Previous research on adults suggests, in an isolated manner, the relationship between connectedness to nature, the development of behaviors in favor of the environment, and positive results derived from them, such as happiness and well-being. In the present research, connectedness to nature was considered as a determinant of sustainable behaviors, and happiness was considered as a positive consequence of the latter. This research aimed to demonstrate the relationship between these variables in children. Two hundred and ninety-six children with an average age of 10.42 years old participated in the study, in which they responded to a research instrument that measured connectedness to nature, sustainable behaviors (pro-ecological behavior, frugality, altruism, and equity), and happiness. To analyze the relationships between these variables, a model of structural equations was specified and tested. The results revealed a significant relationship between connectedness to nature and sustainable behaviors, which, in turn, impact happiness. This suggests that children who perceive themselves as more connected to nature tend to perform more sustainable behaviors; also, the more pro-ecological, frugal, altruistic, and equitable the children are, the greater their perceived happiness will be. The implications for studying and promoting sustainable behaviors are discussed within the framework of positive psychology.

Esta investigación tuvo como objetivo probar empíricamente un modelo para explicar la dedicación al estudio y el rendimiento académico, a través de variables cognitivas de estudiantes universitarios, tales como autorregulación, orientación hacia el futuro y estrategias de aprendizaje. Participaron ciento ochenta y siete estudiantes de una universidad al sur de México. En el modelo propuesto se predijo que, la orientación hacia el futuro, autorregulación y estrategias de aprendizaje, influirían en la dedicación al estudio y el rendimiento académico de los estudiantes. El modelo teórico fue probado a través de ecuaciones estructurales y los resultados mostraron indicadores de bondad de ajuste, por lo que los datos respaldan las relaciones propuestas. La relevancia de este estudio radica en su naturaleza integradora, ya que las variables en cuestión han sido estudiadas y su relación con el rendimiento académico ha sido comprobada; sin embargo, la generalidad de las investigaciones ha medido esta relación a través de correlaciones aisladas.

The purpose of the study was to identify the characteristics associated to the good teacher who teaches presential and virtual mode. A total of 713 students participated, distributed in two groups (493 and 220), from different academic programs of a Mexican institution of higher education participated. For data collection, the technique of semantic networks was used, they were presented as stimulus phrase "good presential teacher" and "good virtual teacher". Two semantic networks were obtained, one for presential teacher, generating 269 definers and a network core of 39. The other semantic network was for the virtual teacher, where 118 words and a network nucleus of 37 were generated. The three words that resulted in greater semantic weight were: responsible, respectful and comprehensive for the presential, accessible and available for the virtual. This study concludes that the definition the students do of the good teacher, regardless of the modality, is determined by personal values.

The aim of the study was to adjust the measurement model of an instrument of sources of Self-efficacy for Mathematics to sample of university students from Northeast of Mexico and the sex measurement invariance. A second-order modeling was performed, which shows convergent and discriminant validity, which corresponds to the original Bandura theory of self-efficacy and contains four factors: experience in mastery, social persuasion, vicarious learning, and physiological state (emotional activation). There was adequate goodness of fit of the model in the confirmatory analysis. The advantages of the use of this instrument are discussed for its simplicity and ease of applications, qualification, and interpretation, to be used by teachers, tutors, and advisors of mathematics.

Las investigaciones acerca del bienestar psicológico y su relación con el rendimiento académico de los estudiantes han reportado resultados diversos. La presente investigación tuvo como objetivo determinar la relación entre el bienestar psicológico, el tener éxito en los estudios y el rendimiento académico. Participaron 383 estudiantes universitarios, quienes respondieron a la Escala de Bienestar Psicológico de Ryff. En los resultados se observó que los estudiantes mostraban un alto bienestar psicológico al tener un propósito en la vida y dominar su entorno, y además se consideraban exitosos. Se encontraron relaciones positivas y significativas entre el bienestar psicológico, el número de materias aprobadas y el considerarse un estudiante exitoso. El promedio de calificaciones se asoció con las dimensiones de propósito en la vida, crecimiento personal y dominio del entorno del bienestar psicológico. Los resultados apoyan la premisa de que dicho bienestar se relaciona con el rendimiento académico.

Beyond the challenges presented by obesity itself, a considerable portion of the population encounters prejudice and discriminatory behavior based on their weight and size. This phenomenon, termed weight stigma and weight bias, appears to be perpetuated not only by the broader society but also by healthcare providers, leading to distrust and alienation among individuals with obesity, thereby exacerbating a global issue. Recognizing weight stigma as a violation of human rights and its association with declining health outcomes, there is a pressing need to explore evidence-based strategies for mitigating it within healthcare. This is especially crucial at the early stages of professional development. Methodology: A randomized controlled trial employing a 60 min lecture experimental design was conducted to evaluate changes in conceptions, beliefs, and prejudices toward obesity among healthcare undergraduates (n = 242). Results: Semantic network analysis revealed participants’ conceptualization of obesity as a condition closely linked to diet and sedentary habits. Moreover, three out of four healthcare students considered obesity a disease for which the individual is responsible. While individuals with obesity were described as weak, lazy, and having a high affinity for food, these prejudices decreased following the educational intervention. Conclusion: Following an educational intervention based on the multifactorial nature of obesity and weight stigma, it was possible to modify prejudices and conceptions about obesity among future healthcare professionals.
