Aplicación del análisis de regresión lineal simple para la estimación de los precios de las acciones de Facebook, Inc

Abstract: The linear regression analysis, is a tool that is extremely important in the world of finance, since it allows to carry out projections and forecasts of a dependent variable that is explained by one or more independent variables. The objective of this study was to determine an equation that would allow to estimate the average monthly price of the shares of the company Facebook, Inc., through a simple linear regression model. The betas for the model coefficients were significant for the descent, measured through statistical test both constant t. Likewise, global test of significance of the beta coefficients, determined through statistical test F, this proved to be highly significant, which allowed the validation of the model.

A new species and immature stages of the skiff beetle genus Yara Reichardt and Hinton (Coleoptera: Myxophaga: Hydroscaphidae) from Nicaragua.

Abstract: Yara marmontsedu, a new species in the family Hydroscaphidae (Coleoptera: Myxophaga), is described and illustrated. Specimens of Y. marmontsedu were collected at the Pijibay Creek, tributary of the Mico River in Chontales, Nicaragua. The immature stages are described and illustrated for the first time for a species of Yara. This is a contribution to the knowledge of the water beetle fauna of Nicaragua.

Hacia un modelo de clases participativas de Ciencias Sociales en Educación Secundaria

Abstract: The 21st century has been a century of substantial educational changes; teachers have been involved in a deep process of pedagogical self-reflection that has led to the appropriation of the discourse of educational innovations as an essential element to obtain improvements in educational results. Among this network of innovations placed at the center of discussion of the academic debate, the present essay aims to generate a space for educational reflection among practicing and training teachers, around the participatory methodologies of students in social science classes as an essential factor within pedagogical innovation. To do this, the essay begins by making a dense journey through the problems related to didactic methodologies and the little role that the student has in them, then raises the issue of participatory methodologies as an element of educational innovation in learning processes, in order to finally lay the foundations of the challenges faced by teachers regarding the implementation of participatory methodologies in the classroom, taking as a main reference the context of the society that advances and innovates day by day.

Gestión de los recursos hídricos

Abstract: El presente trabajo se basa en resultados presentados por especialistas en recursos hidricos sobre experiencias de los sectores mas vulnerables a sequia y aquellos que demandan agua de calidad tomando como referencia las zonas cafetaleras del norte de Nicaragua. Con base a una recopilacion de informacion existente asi como de entrevistas y talleres participativos utilizando plataformas de dialogo territorial con el objetivo de identificar las trayectorias mas probables que podrian disminuir la vulnerabilidad de los productores de cafe ( Coffea arabica ) al cambio y variabilidad climatica. En las conclusiones del estudio mencionamos que la tecnologia de produccion de cafe multiestrato con banano es un tema ampliamente estudiado utilizando un enfoque que aplica herramientas de toma de decision para manejar la productividad del sistema - manejo del recurso luz, ciclos de nutrientes y optimizacion del banano como cultivo secundario, entre otros. Es necesario desarrollar un proceso participativo innovador para mejorar la gestion de los recursos hidricos en comunidades cafetaleras para incrementar su capacidad de adaptacion y resiliencia frente al cambio climatico (variabilidad de las lluvias y las sequias).
