    New records of invasive tubeworms (Ficopomatus, Serpulidae) in Mexico by Tovar Hernández, María Ana, De León González, Jesús Ángel, Kupriyanova, Elena K.

    Published 2022
    “…Comparison of mitochondrial cytochrome b (Cytb) DNA sequences further support the notion that F. miamiensis from the type locality (Florida) and Atlantic coasts of Mexico is also found along the Pacific coast of Mexico. Morphological variability within specimens of F. uschakovi from a single locality (either Laguna del Ostión or La Encrucijada) in Mexico suggest potential presence of multiple cryptic species. …”

    Solar-driven CO2 reduction using modified earth-abundant ilmenite catalysts by Luévano Hipólito, E., Fabela Cedillo, Mayte G., Torres Martínez, Leticia M., Zarazúa Morín, María E.

    Published 2023
    “…It was found that higher synthesis temperatures promoted the formation of Fe3+ species, which decreased the efficiency for CO2 reduction. Also, the possibility of reduced the CO2 molecules in the air was studied with the NaFeTiO4 samples, which resulted in an efficiency of up to 93 μmol g− 1 h− 1 of HCOOH under visible light. …”

    Pre-competitive anxiety and self-confidence in pan american gymnasts by Ceballos Gurrola, Oswaldo, Pineda Espejel, Heriberto Antonio, López Walle, Jeanette M., Tristán Rodríguez, José Leandro, Medina Villanueva, Mireya

    Published 2013
    “…The results revealed that the intensity and direction of cognitive anxiety were positively correlated with the intensity and direction of somatic anxiety (r = .55 and r = .53, respectively), while self-confidence was negatively correlated with the intensity of cognitive anxiety (r = - 305) and also predicted it (β = - .192). Women reported significantly higher perceived somatic anxiety levels (2.79) than men (2.48). …”

    Clima motivacional percibido, motivación autodeterminada y autoestima en jóvenes deportistas mexicanos by López Walle, Jeanette M., Balaguer Solá, Isabel, Castillo Fernández, Isabel María, Tristán Rodríguez, José Leandro

    Published 2011
    “…Within the framework of the Achievement Goal Theory (Ames, 1992; Dweck, 1999; Nicholls, 1989) and Self-Determination Theory (Deci and Ryan, 1985, 2000), this study tested a model with the following sequence: perceived motivational climate (task and ego involvement), self-esteem, self-determined motivation. It also examined whether selfdetermined motivation acted as a mediator between the two dimensions of perceived motivational climate (task and ego involvement climate) and self-esteem. …”
