Entre la multiplicidad de castigos en la Duat, la situación de los que aparecen en posición invertida tanto en los textos como en las representaciones es una de las más llamativas por cuanto no tiene un correlato con la realidad, como sí lo tienen la decapitación, la incineración de cuerpos o la inmovilización por sujeción. La variedad de castigos es amplia, pero por su característica, por las reiteradas menciones en los textos y por la diversidad de explicaciones que se han ensayado al respecto, la situación de estos sxd.w es particularmente interesante. Lo que este estudio se propone, además de un recorrido por los diferentes contextos funerarios en que se los cita, es explicar su significación para entender por qué era uno de los castigos más temidos por los condenados.

During development, in her regular interaction with the child, the mother uses some techniques or procedures (i.e. instigating, asking questions, modeling behaviors) to guide, monitor, shape and/or provide feedback to the child’s behavior. Those teaching behaviors may take place in the context of normal interactions like playing or caring routines, facilitating the acquisition of different types of skills in the child. The present study analizes the effectivity of the activities of the mother in the acquisition of new cognitive achievements in the child between 29 and 54-mo.old. It discusses the trajectory of the child achievements and the dynamics of the mother-child interaction.

Introduction: The WHO states that globally there are 200,000 homicides among young people aged 10-29 years, most homicides are male. Mexico ranks first in this category of behaviors, with a higher prevalence among adolescent males. There are few studies that relate hormonal factors with behavioral factors in this population.  Objective: To evaluate the relationship between interpersonal factors, cortisol levels and aggressive behaviors in addicted adolescents with a criminal history.  Methodology: 12 adolescents with a criminal history and 12 adolescents without a criminal history were recruited. Questionnaires on general data, reactive and proactive aggression, impulsivity, aggression, and a psychopathy interview were administered. Daytime saliva samples were taken for subsequent cortisol quantification by ELISA. Results: Adolescents with a delinquent history presented significantly higher levels of reactive (t=3.29, p˂0.005) and proactive (t=6.72, p˂0.001) aggression; they also presented higher levels of general impulsivity (t=2.8, p˂0.03) and unplanned impulsivity (t=2.58, p˂0.02). This group of adolescents presented significantly high levels of physical aggression (t=6.55, p˂0.001), hostility (t=2.79, p˂0.02), anger (t=3.95, p˂0.002) and verbal aggressiveness (t=2.95, p˂0.008). Adolescents with delinquent background presented significantly high levels in interpersonal (t=4.44, p˂0.0001) and affective psychopathic traits (t=6.97, p˂0.0001), impulsivity, parasitic lifestyle and irresponsibility (t=4.95, p˂0. 0001), in antisocial behavior and lack of self-control (t=7.25, p˂0.0001); when classifying the level of psychopathy, adolescents with a criminal history present a medium level of psychopathy and those in the control group have low levels of psychopathy (t=8.33, p˂0.0001). Referring to cortisol levels, adolescents with delinquent history presented lower levels of cortisol in saliva at fifteen minutes after awakening (t=-2.53, p˂0.02) and at thirty minutes after awakening (t=-2.43, p˂0.03). Cortisol levels upon awakening were found to be inversely related to hostility (R=-0.499) and to reactive (R=-0.47) and proactive (R=-0.45) aggression. While cortisol levels before sleep also present an inverse correlation with the levels of reactive aggression (R=-0.47), proactive aggression (R=-0.57) and the hostility factor (R=-0.41). Conclusion: Adolescents with a criminal history present higher level of aggression, impulsivity, greater interpersonal psychopathic traits, affective, parasitic behavior, and a considerable lack of control. With higher mean levels of psychopathy than the control group. Cortisol levels upon awakening and before sleeping are inversely proportional to the levels of hostility, reactive and proactive aggression.

La diabetes es una enfermedad crónica que se caracteriza por una deficiencia en la producción o utilización de insulina y se encuentra entre las principales causas de muerte en México. Si no se controla adecuadamente, esta condición puede dar lugar al pie diabético, lo cual incrementa el riesgo de amputaciones, ya sean parciales o totales, en los miembros inferiores. Por ello, es fundamental que los pacientes con diabetes adopten conductas de autocuidado para prevenir esta complicación. Objetivo: Evaluar la eficacia de un programa multicomponente cognitivo conductual para desarrollar conductas de autocuidado del pie en pacientes con DM II ingresados en un hospital público. Participaron cinco pacientes. La intervención se llevó a cabo en cinco sesiones con técnicas de psicoeducación, modelado y moldeamiento. Se usó un diseño pretest, postest, con seguimientos semanales y mensual, aplicando los instrumentos: Diabetes Knowledge Questionnaire 24, una checklist sobre autocuidado, un cuestionario de conocimientos sobre autocuidado del pie y autorregistros de conductas de autocuidado. Se realizó un análisis grupal con la prueba rangos de Wilcoxon y uno individual con el Cambio Clínico Objetivo (CCO) y el Porcentaje de Datos no Solapados (PND). Los resultados obtenidos mostraron diferencias significativas en el nivel de conocimiento de autocuidado en la evaluación pretest y postest. Así como valores 20%> de CCO y PND del 100% indicando efectividad del tratamiento; aunque hubo muerte experimental y solo un paciente completó al 100% el programa. Se discute la importancia de implementar programas que fortalezcan conocimientos y autocuidados que eviten complicaciones graves como el pie diabético

Currently, there is a low rate of research preparation and execution in the Bachelor's Degree in French Teaching. Therefore, the purpose of this study is to characterize students' difficulties, based on their own opinions, when conducting research using a longitudinal-descriptive qualitative approach. To this end, eight students participated in three interviews. The results let to characterize research difficulties, grouped into three categories: 1. Training in research skills with a grasp of research concepts at a theoretical level. 2. Research skills that frame the difficulties or lack of skills at the practical level in posing the problem, formulating objectives, developing the theoretical framework, implementing methodological designs, choosing techniques and instruments, and writing an academic transcript in a foreign language. 3. Attitudes toward the research process that demonstrate interest and initiative in research despite having basic experience and difficulties conducting it. This allows for reflection on the importance of practice in relation to theory, which represents a gap between knowledge and application, emphasizing the need for a teaching methodology to address it. In conclusion, research requires both solid theoretical knowledge and investigative skills that help put what has been learned into practice, systematize information, and describe a study.

Eutudora jimenoi is a Cuban terrestrial mollusk of the Annulariidae family, local endemic to the karstic elevations at Tapaste-Jaruco in Mayabeque. In this paper, a detailed description of the E. jimenoi radula was carried out, accompanied by images of its radular anatomy obtained from Scanning Electron Microscopy. As additional information, color images of the shell, operculum and external morphology of this mollusk were incorporated. The distinctive characteristics of the radula in this species are the following: unicuspid rachidian and curved inwards teeth, triangular outline and height 1/3 greater than its base, its distal area with triangular- ovate shape and slightly shaperned cutting edges; unicuspid lateral and curved inwards teeth, triangular outline, slightly higher than rachidian teeth, with very wide bases that reach dimensions relatively equal to their heights, its distal area with a petaloid shape and rounded cutting edges; inner marginal teeth with narrow and flattened bases, curved outwards towards the outer marginal teeth of the same row, covering over or overlapping the interior cusps of the outer marginal teeth, its distal area is spatuliform with smooth cutting edges and the presence of an external lateral denticle; concave outer marginal teeth, very wide and with pectinate cutting edges that have just over 100 long and curved cusps that gradually decrease in size towards their outer sides. The results offered constitute a contribution to the taxonomic description and natural history of this mollusk included in the near-threatened category on the Red List of terrestrial invertebrates of Cuba.
