Diseño de una escala de ADN organizacional y engagement aplicada en dos empresas del estado de Nuevo León por Rojas Torres, Stephany María

“…It is concluded that the levels of Organizational DNA and Engagement are very high, that the type of DNA are distributed proportionally without any specific type, and that for this first approach from the sample obtained there is no significant correlation between the variables or dimensions, so it is recommended to extend the evaluation with a larger sample in order to determine how the scale is going to behave and what important variations it may present.…”

Mineralogical and geochemical evidence of magma mingling/mixing in the Sierra de las Cruces volcanic range, Mexican Volcanic Belt por Velasco Tapia, Fernando, Rodríguez Saavedra, Pedro, Márquez, A., Navarro de León, Ignacio, De Ignacio, Cristina, Marroquín Guerra, Sylvia Gabriela, Quintanilla Garza, Jesús, Rangel Alvarez, Oscar Mario

“…The evidences of magma mixing and mingling include: (a) normal and sieved plagioclases in the same sample, rounded and embayed crystals, and armoured rims over the dissolved crystal surfaces; (b) subrounded, vesicular magmatic enclaves, ranging from a few millimeters to ~20 centimeters in size, with plagioclase + orthopyroxene + amphibole + quartz ± olivine ± Fe-Ti-oxides assemblage; (c) mineral chemistry evidence such as crystals with reaction rims or heterogeneous plagioclase compositions (inverse and oscillatory zoning or normally and inversely zoned crystals) in the same sample; and (d) elemental geochemical variations and trace-element ratio more akin to magma mixing and to some extent diffusion process. …”
