The purpose of this research is to formulate a theory of self-transformation based on Avicenna’s psychology. The research method used is descriptive qualitative analysis. Self-transformation is the process of changing the soul quality as to produce better changes in perception and behavior. The background of the research includes the weaknesses of the existing self-transformation methods; Avicenna’s psychology directs the soul to perfect the transformation; Avicenna’s psychology does not discuss his self-transformation theory explicitly; Avicenna has a better formulation of self-transformation theory (...) than Aristotle implicitly; and it provides alternative self-transformation method.

Objectives: This study explored a multidimensional model of the relationships between social media use, gender, peer bullying victimization experiences, and the onset of anxiety symptoms among children. We hypothesized that greater experience of bullying would be associated with greater onset of anxiety. We also expected that gender and social media use would be linked with anxiety among elementary school children. To test this hypothesis, a structural equation modeling approach was used.Methods: A total of 456 elementary children aged 11–13 years from (...) nine schools were recruited for this research. We used two psychological measures: The Screen for Child Anxiety Related Emotional Disorders and the Personal Experience Checklist as well as a sociodemographic questionnaire.Results: The social media usage survey found that all participants used social media. Instagram and YouTube were the platforms most used by the participants. The Structural Equation Model results suggest that bullying victimization and gender predicted the onset of anxiety in elementary school children. The model explained 32.1% of the variance of the outcome with very adequate fit indicators based on most indices, χ2 = 173.56, df = 52, p < 0.001; CFI = 0.92; TLI = 0.94; RMSEA = 0.07. Instagram use was correlated positively with generalized anxiety disorder. Gender was negatively correlated with Instagram use and positively correlated with YouTube use. Girls were found to use Instagram more and boys were found to use YouTube more. It was also found that girls had higher scores onSCARED dimensions, except for school avoidance. Girls were more prone to onset of anxiety than boys, except for school avoidance, which was not related to gender. Boys were found to experience significantly more physical bullying than girls. On the other hand, girls were found to experience more panic disorder, generalized anxiety disorder, separation anxiety disorder, and social anxiety than boys.Conclusion: This study found that bullying victimization significantly influences the onset of anxiety in children. Particular attention should be paid to cyberbullying in this context. This study also found a link between gender and anxiety—girls had a greater tendency to experience the onset of various types of anxiety, including panic disorder, generalized anxiety disorder, separation anxiety disorder, and social anxiety. Gender was also correlated with the form of bullying victimization. The findings of this study suggest that boys were more likely to experience physical bullying than girls. Interestingly, we found that Instagram use was significantly correlated with developing separation anxiety. In particular, children demonstrated school avoidance when experiencing cyberbullying. Limitations and future directions are discussed. (shrink)

En este trabajo se presenta una comparación de los tiempos de respuesta, optimización de la ruta y complejidad del grafo en métodos de planificación de trayectoria para robots móviles autónomos. Se contrastan los desarrollos de Voronoi, Campos potenciales, Roadmap probabilístico y Descomposición en celdas para la navegación en un mismo entorno y validándolos para un número variable de obstáculos. Las evaluaciones demuestran que el método de generación de trayectoria por Campos Potenciales, mejora la navegación respecto de la menor ruta obtenida, (...) el método Rapidly Random Tree genera los grafos de menor complejidad y el método Descomposición en celdas, se desempeña con menor tiempo de respuesta y menor coste computacional. Palabras Clave: optimización, trayectoria, métodos de planificación, robots móviles. Referencias [1]H. Ajeil, K. Ibraheem, A. Sahib y J.
