Satisfaction of an employee in a sports entity: design and validation of a measurement scale by Reyes Robles, Marina, Medina Rodríguez, Rosa Elena, Ramírez Siqueiros, María Grethel, López Walle, Jeanette M., Ceballos Gurrola, Oswaldo

“…Satisfactory values were obtained, resulting in Kaiser-Meyer-Olkin values of .91, and the Bartlett test was statistically significant with a value (χ² = 3296.01, gl = 378; p <. 001), six factors were extracted with eigen values greater than 1 and that together explain 69.08% of the total variance. the indices of the model in the confirmatory factor analysis were satisfactory: χ2 / df = 1.29, NNFI = .99, CFI = .99, and RMSEA = .03., The results of internal consistency using Cronbach's alpha index with values in this case greater than .70, composite reliability (CR) with values between .88 and .94, and the average variance index extracted (AVE), meanwhile, alsoshowed adequate values, in a range between .60 and .83. …”

Relocation and seismotectonic interpretation of the seismic swarm of August – December of 2012 in the Linares area, northeastern Mexico by Gómez Arredondo, Carmen Maricela, Montalvo Arrieta, Juan Carlos, Iglesias Mendoza, Arturo, Espindola Castro, Victor H.

“…The fault plane solutions were generated for individual earthquakes and through the use of the composite mechanism technique. The focal mechanism solutions show pure reverse faulting; the SW dipping NNW – SSE trending nodal plane is the inferred fault plane (strike ~150°, dip ~50° and rake ~67°), which reveals that maximum horizontal stress (SHmax > Shmin > Sv) predominates in the area. …”

Caracterización de las sucesiones areno - conglomeráticas del eoceno en la región de las Choapas, Veracruz. by Coronado González, Jesús Margil

“…With the isotope geochemistry of Sm/Nd, the isotopic ratios, model ages and Nd epsilon were obtained, in order to be correlated with data of possible source areas. Rocks with compositions similar to those identified in this work have been described in the Chiapas Massif and the Guichicovi Complex, in the Maya Block; and in complexes exhumed by the Polochic-Motagua Fault System, in Chortis Block.…”

Artificial neural network modeling of phenol adsorption onto barley husks activated carbon in an airlift reactor by Loredo Cancino, Margarita

“…Purpose and method of the study: The production of activated carbon from barley husks (BH) by chemical activation with zinc chloride was optimized by using a 23 factorial design with replicates at the central point, followed by a central composite design with two responses (the yield and iodine number) and three factors (the activation temperature, activation time, and impregnation ratio). …”
