Abstract: El objetivo de este trabajo es proporcionar una guia metodologica para la determinacion de los riesgos en la ejecucion de los procesos de la organizacion, mediante la medicion del riesgo de gestion del Control Interno, el mismo que tiene como enfoque la ponderacion y evaluacion del impacto del riesgo empresariales para entidades del sector publico y privado. La metodologia utilizada permite construir una Matriz de Riesgo, con el proposito de evaluar la gestion del riesgo empresariales mediante la ponderacion del impacto y la probabilidad de ocurrencia, mediante los parametros del Enterprise Risk Management Framework conocido como COSO ERM o COSO II, que gestiona los riesgos corporativos y las disposiciones vigentes en relacion a la gestion de riesgos operativos. La Matriz de Riesgo aplica permite determinar un plan de accion para los procesos que se encuentra con mayor impacto de riesgos empresariales y con la mayor frecuencia de ocurrencia , los cuales afectan a la gestion administrativa de la organizacion. Esto permitara disenar estrategias de mitigacion de riesgo empresarial mediante la aplicacion de indicadores de cumplimiento.

TL;DR: In this article, the authors present an exploración on the estilos de aprendizaje of the discentes of the Facultades de Filosofia, Letras and Ciencias de la Educación and Cientías Agricolas de the Universidad Central del Ecuador.
Abstract: La forma como los estudiantes enfrentan los estudios universitarios da paso a esta investigacion en la que se estudio los estilos de aprendizaje de los discentes de las Facultades de Filosofia, Letras y Ciencias de la Educacion y Ciencias Agricolas de la Universidad Central del Ecuador. Este estudio incluyo estudiantes que cursaban diferentes semestres con la finalidad de observar posibles variantes en el estilo de aprendizaje. El instrumento utilizado para obtener la informacion fue el cuestionario de Estilos de Aprendizaje de Honey-Alonso (CHAEA), utilizado ampliamente en estudios universitarios. El tipo de investigacion fue descriptivo-transversal, realizado en el inicio del semestre 2017-2017, con una muestra total de 431 estudiantes sin diferenciacion de genero. Los resultados obtenidos indican la preferencia por el estilo reflexivo, seguido por el estilo pragmatico, teorico y activo. La preferencia por el estilo reflexivo se mantiene en todos los semestres. Finalmente se concluye que esta investigacion aporta datos importantes para establecer estrategias de ensenanza-aprendizaje para mejorar la educacion universitaria.

TL;DR: In this paper, the authors explain how feminist actors identified with the sumak kawsay discourse of indigenous women around the care of the environment, children and women living in communities, linking it with the decriminalization of abortion and bringing it together under the proposal of "management of life".
Abstract: This article explains how feminist actors identified with the sumak kawsay discourse of indigenous women around the care of the environment, children and women living in communities, linking it with the decriminalization of abortion and bringing it together under the proposal of “management of life” in an historical moment in which peasant and urban women had been strongly questioned by the government of the citizen revolution in Ecuador. So, after making a small historical journey through milestones of feminisms, we explain how this process of identification was.

TL;DR: In this paper, a set of seven new chromones with 2-haloalkyl and 3-bromo and bromomethyl substituents were synthesized, and they were studied by DFT calculations and characterized by vibrational spectroscopy (IR and Raman) in solid state, and NMR (1H, 13C and 19F) and UV-vis spectrograph in solution.

TL;DR: In this study, aqueous extracts of Calliandra haematocephala Hassk.
Abstract: In this study, aqueous extracts of Calliandra haematocephala Hassk. leaves and inflorescences were tested on seeds of quinoa (Chenopodium album L.) and rice (Oryza sativa L.), and on some of the most noxious-associated weeds, Chenopodium album L. and Holcus lanatus L. in quinoa, and Echinochloa crus-galli (L.) P. Beauv., Echinochloa colona L., Eclipta prostrata L. and Rottboellia cochinchinensis (Lou.) W.D. Clayton in rice. The objectives were to identify extract concentrations at which 50 and 90% of germination (GR$$_{[50,90]}$$) and radicle elongation (RR$$_{[50,90]}$$) were inhibited, to fractionate inflorescence extracts for facilitating identifying the chemical group causing allelopathic effects, and to evaluate the fraction showing the stronger weed suppression effects and the least crop damage. Increasing extract concentration rates (0, 6.25, 12.5, 25, 50 and 100% crude extract) were applied to seeds of target crops and weeds. Flower extracts at rates $$ 0.52$$ caused the RR$$_{[50]}$$ on rice and all its target weeds. Fractions were quantitatively and qualitatively analysed to detect phytochemical groups, using specific chemical reagents and thin-layer chromatography (TLC). The fraction F3 from aqueous flower extract showed a high content of flavonoids, assumed as the potential allelochemical substance. Total flavonoid content in F3 was quantified as 2.7 mg of quercetin per g F3, i.e., 12.8 mg of quercetin per g of inflorescence material. Additionally, field equivalent extract rates obtained from the harvested fresh inflorescence biomass could be determined. These rates ranged between 90 and 143 mL l−1 of F3 aqueous fraction, while for ethanol F3 were 131 mL l−1. Our results are encouraging for finding sustainable and ecologically friendly alternatives for weed management in crops of high nutritional value, contributing also to counteract the growing problem of herbicide resistance.
