Las habilidades de un investigador, son condiciones básicas, cuya actividad principal es buscar nuevos conocimientos en el campo científico; La presente investigación tuvo como objetivo principal, diagnosticar el nivel de desarrollo de habilidades investigativas de los maestrandos. El diseño de investigación fue descriptivo evaluativo y la muestra de 65 sujetos, a quienes se les aplicaron un cuestionario con respuestas en escala de Likert. De acuerdo a las habilidades observadas, los resultados evidencian lo siguiente, en el conocimiento empírico analítico un 13,8% demuestran un desarrollo muy alto; medio un 30,8% y bajo el 33,8%. En el conocimiento histórico hermenéutico el 1,5% alcanzo un desarrollo muy alto, medio el 20% y bajo el 35,4% y; por último, en conocimiento crítico el 4,6% muestran un desarrollo muy alto, medio el 30,8%, y bajo el 43,1% . Se concluye que, no exist...

Objective: To determine the effects of the “Free of COVID-19” educational program on the preventive social skills of teenagers treated at a provincial hospital in Peru. Materials and methods: An explanatory, pre-experimental, longitudinal and prospective research with a pretest and posttest intact group design. The population consisted of 40 male and female teenagers aged between 13 and 19, who were treated at the Tayabamba provincial hospital. The inclusion criteria were a) teenagers aged between 13 and 19, b) teenagers with complete medical records and c) teenagers treated at the Tayabamba provincial hospital. The variables (before and after the program) were the preventive social skills and their dimensions: assertiveness, communication, self-esteem and decision-making. The “Free of COVID-19” educational program was implemented with a pretest and a posttest. A questionnaire ma...

Currently, great importance has been given to the study of external morphology, especially in fish, when it is used as a means of identifying hybrids. This paper considers a LASSO model based on the truss protocol to compare morphological covarion patterns between specimens of Colossoma macropomum and the hybrid C. macropomum (♀) x P. orinoquensis (♂). In this study, 25 specimens of C. macropomum and 20 specimens of the hybrid C. macropomum (♀) x P. orinoquensis (♂), respectively, were analyzed. The method "Truss protocol" or "trusses" Strauss and Bookstein (1982) was used. LASSO model achieved to reduce the mean squared error. The final model obtained contains only seven covariates. LASSO model fitted on the morphological covariation patterns between specimens of C. macropomum and the hybrid C. macropomum (♀) x P. orinoquensis (♂) showed a good fit and allowed to correctly c...
