The purpose of this research is to analyze the psychometric properties of the scale of family parenting styles (ECF-29), supported by structural equations, a multivariate statistical analysis to compare models that propose causal relationships between variables. The sample consisted of 609 students of public educational institutions, from the 1st to 5th year of high school, and whose ages were between 11 and 18 years, from the districs of Los Olivos and Independencia. There were selected by intentional sampling and the estimation model used is the maximum plausibility. The results revealed the covariances, variances and factorial saturations as adequate; likewise, the styles are estimated according to the absolute adjustment indexes (GFI, AGFI>0.95, RMSEA and RMR<0.05) and increase or comparative values (TLI, NFI and IFC>=0.95) with optimal values corroborate the pertinence of a...

The largest and most successful companies in the world have not always been that way. The challenges they have faced in order to become what they are today may have been countless. In contrast, while many companies have achieved significant levels of growth, they have not all been able to maintain their success in the long term, even to the point of starting to fail. This Thesis provides a conceptual framework that tends to explain the effect of CE that encompass I and SR on BP in Colombian companies, so the lack of CE, I and SR moderated by size of and sector/industry, might lead the Colombian companies to BF or OD. The research was developed using the information provided by regulatory entities in Colombia. The information gathered included both financial and managerial information submitted to the Colombian Superintendency of Corporations by companies that have entered into the restru...

El bienestar subjetivo constituye uno de los temas centrales en la agenda de las ciencias sociales y en la política internacional. Es también un tema central en la psicología contemporánea, en donde se ha acumulado evidencia acerca de sus componentes. El reto es integrar ese conocimiento en un modelo. Se parte del modelo multidimensional de bienestar subjetivo y se adapta para una muestra representativa de Lima Metropolitana. Dado que los estudios previos se basaron en muestras no representativas de zonas rurales y peri urbanas peruanas, el presente estudio constituye un avance en la línea de investigación. Se propone un modelo en donde los valores influyen en las metas y en la percepción de logro de las metas; y que los recursos son mediadores entre las metas y su percepción de logro. Se encuentra evidencia confirmatoria del modelo. Se utilizó la técnica del análisis de camin...

En el contexto económico actual, la eficiencia en la ejecución de los proyectos de construcción es crucial, y la adopción de Lean Construction (LC) se destaca como una estrategia para maximizar el valor agregado al usuario final, reducir el desperdicio y optimizar el flujo de producción en los proyectos. La implementación de LC implica un viaje progresivo que requiere evaluaciones periódicas para verificar el progreso y abordar las debilidades. Sin embargo, la falta de consenso en la ruta de implementación de LC y la escasa disponibilidad de modelos y/o herramientas para evaluar la adopción de LC, son áreas de preocupación identificadas en la literatura. En este documento el autor de la presente tesis propone abordar la problemática mencionada, a partir de un estudio riguroso sobre el conocimiento existente de LC y sus buenas prácticas en el mundo. Para lograr dicho fin, est...

Las redes cooperativas a través de relays son una técnica prometedora utilizada para mejorar las comunicaciones inalámbricas en términos de diversidad, cobertura y ahorro de energía. AAmplify-and-forward (AF) y Detect-and-forward (DF) son los protocolos de cooperación más utilizados, que operan en dos fases: la fase de transmisión y la fase de retransmisión. En AF, el relay recibe la señal de la fuente durante la primera fase, la amplifica y la retransmite al destino. Mientras tanto, en DF, el relay recibe la señal, la detecta y envía el símbolo detectado al destino. Por otro lado, en las redes celulares, la interferencia cocanal (CCI) es uno de los principales problemas que degradan el rendimiento, especialmente cuando se utiliza una alta reutilización de canal. En este escenario, el combinador óptimo surge como la técnica que maximiza la relación señal-interferencia-m...

Academic behavior currently represents an important variable to be addressed, it is greatly linked to the family environment; however, when the interaction is inadequate it can trigger reactive behaviors. The present study aimed to analyze the scientific literature in relation to reactive academic behavior in adolescents because of family violence. A literature review was carried out in five databases Scopus (392), PubMed (462), SciELO (5), Redalyc (2788) and Web of Science (118) with a total of 3765 articles, of which 18 documents were systematized that met the selection criteria established by the PRISMA model. The results showed that 22.2% of the articles came from Brazil, 16.7% from the United States, 11.1% from China, Mexico and Turkey, and 5.6% from countries such as Canada, Spain, Peru, Sweden and Thailand. The review shows that 100% were quantitative studies, 55.6% were cross-sec...

Argumentation is a process in which reasons and justifications are produced to support a point of view. It has been widely studied due to its relationship with cognitive change and its significance in education at all levels. The present research aimed to explore three cases of university students engaged in debates across three distinct contexts (persuasion, consensus, and free debate) and their influence on the development of dialogue. The study analyzed argumentation and socio-cognitive integration, defined as the ability of students to incorporate information contributed during the debate. The findings align with previous studies but emphasize the importance of examining individual student characteristics in achieving effective socio-cognitive integration and dialogue development. Furthermore, potential theoretical and methodological implications are discussed.

The aim of this study was to determine the effect of papain treatment on the kinetics of llama sperm. Four 5-8-year-old Ch'aku male llamas were selected and semen was collected using an artificial vagina and a dummy. Four semen collections were made per animal with intervals of one week. The semen samples were separated into two aliquots. One for fresh analysis and the other to be treated with papain (20 minutes). The volume, filancia, concentration of sperm, percentage of live sperm, percentage of functionality of the sperm membrane, and percentage of sperm with acrosomal reaction were evaluated. Sperm mobility and its kinetics were evaluated using a CASA-Mot system (ISAS®), determining the total motility (MT) and progressive motility (MP), as well as the sperm kinetic parameters: curvilinear velocity (VCL), straight-line velocity (VSL), average path velocity (VAP), and the indices of ...

Las viviendas con condiciones adecuadas son una necesidad básica de las personas debido a que son primordiales para la seguridad, la salud y la dignidad humana, elementos que contribuyen a desarrollar su potencial. A pesar de que el Índice de Progreso Social (IPS) 2017 ubicó al Perú dentro de una clasificación «Alta» (Porter & Stern, 2017), los resultados del IPS Regional pusieron en evidencia las grandes diferencias sobre las condiciones habitacionales que existen al interior del país, con mejores condiciones en los hogares de la mayoría de las regiones de la costa, ubicándolas en las clasificaciones «Alta» y «Muy alta»; y, por el contrario, las escasas condiciones en la mayoría de las regiones de la sierra y selva, ubicándolas en las categorías «Baja» y «Muy baja» (CENTRUM Católica Graduate Business School [CENTRUM] & Social Progress Imperative [SPI], 2016a). La p...

Esta investigación ha identificado los factores que favorecen o dificultan la implementación del Programa de Educación para la Sexualidad y Construcción de la Ciudadanía (PESCC) en los colegios públicos del municipio de Guateque (Boyacá, Colombia), partiendo del supuesto de que la institucionalidad de una política o programa, es un componente de carácter trasversal cuyo estudio contribuye a lograr mayor eficacia y eficiencia en la gestión de las políticas sociales. Las políticas atraviesan un ciclo y tienen un conjunto de componentes, en la base de todo ello, se encuentra la institucionalidad que la gestiona e implementa, y constituye un elemento clave para su funcionamiento, en la medida que es su soporte. Esta institucionalidad posee una lógica y características propias y es también susceptible de constituirse en campo de análisis (Tovar, 2013). Los aspectos relativos a...
