Ethnic-Racial Identity and Social Outcomes in Childhood: A Research Review

Ethnic-Racial Identity and Social Outcomes in Childhood: A Research Review Grace Bryan, Dept. of Sculpture, Keyri Hernandez, and Chloe Walker and Eryn DeLaney, Dept. of Psychology Graduate Students, with Dr. Chelsea Williams, Dept. of Psychology Ethnic-racial Identity (ERI) is the labeling, identification, and processing regarding ethnicity-race that takes place during childhood (Umana-Taylor, 2014). Development of ERI begins as early as 4 years (Derlan et al., 2017), and may have implications for social outcomes, such as prosocial and externalizing behaviors. The aim of the current narrative review was to review research that has tested how ERI is associated with social outcomes, and identify gaps in this field. The results of the narrative review suggest that, in adolescence, higher ERI is associated with better social outcomes, such as prosocial behaviors (Armenta et al 2011:Streit et al 2020). Further, findings of the review indicated that limited work has included individuals younger than adolescents; one study that did found that lower ERI was linked with more externalizing problem behaviors (Smith et al., 2009). The review also highlighted various gaps in this literature, such as that an operational definition of prosocial behavior in the context of ERI needs to be established, and there is a lack of research that includes multiracial individuals, and individuals younger than adolescents. Future research should investigate ERI and social outcomes in childhood with diverse samples, as such research may provide important information to school systems, counselors, and caregivers about the development of ERI and its implications for development.https://scholarscompass.vcu.edu/uresposters/1299/thumbnail.jp

The Intertwined Renewable Energy–Water–Environment (REWE) Nexus Challenges and Opportunities: A Case Study of California

In our built environment, societal production of energy and clean water is inextricably linked to the natural resources from which they are derived. Acknowledgement and consideration of the coupling of energy, water, and the environment (the energy–water–environment nexus) will be critical to a sustainable future. This is particularly true as we transition away from historical energy sources (e.g., coal, petroleum, natural gas) and into the widespread adaptation of renewable energy (RE) sources (e.g., solar, wind, geothermal, hydro, bioenergy) as a strategy to decrease greenhouse gas emissions and consequently slow global climate change. This transition is fraught with both challenges and opportunities at the county, state, national, and international levels, as addressing future societal needs with respect to energy and water, and the environment requires recognition of their interdependence and development of new technologies and societal practices. In this study, the focus is on the RE–water–environment (REWE) nexus. In California, the REWE nexus is becoming increasingly important in achieving 100% clean electricity from eligible RE and zero-carbon resources by 2045 and in the face of climate change and population and economic growth. In this context, California’s RE deployment and renewable electrical generation, its RE legislative information, REWE nexus, and intertwined REWE nexus challenges and opportunities in California (e.g., administrative–legal, technology development, digitalization, and end-of-life RE waste) are comprehensively discussed to identify the knowledge gaps in this nexus and solutions

Comparison of reaction networks of Wnt signaling

Wnt signaling is a vital biological mechanism that regulates crucial development processes and maintenance of tissue homeostasis. Here, we extended the parameter-free analysis of four mathematical models of the beta-catenin-dependent Wnt signaling pathway performed by MacLean et al. (PNAS USA 2015) using chemical reaction network theory. We showed that the reaction networks of the four models considered (Lee, Schmitz, MacLean, and Feinberg) coincide in basic structural and kinetic properties except in their mono-stationarity/multi-stationarity, and their capacity for admitting a degenerate equilibrium. Moreover, we showed that the embedded networks of the Lee and Feinberg models are very similar, and the discordance of the Lee network limits its mono-stationarity to mass action kinetics, which challenge the absoluteness of model discrimination into mono-stationarity versus multi-stationarity alone. Focusing, henceforth, on the three multi-stationary networks, we showed that their finest independent decompositions are very different and can be used to study further similarities and differences among them. We also determined equilibria parametrizations of the networks and inferred the presence of species with absolute concentration robustness. Finally, direct comparison of the Schmitz and Feinberg networks with the MacLean network yielded new results in three aspects: structural/kinetic relationships between embedded networks relative to their set of common species, connections between the positive equilibria of the subnetwork of common reactions and the positive equilibria of the whole networks, and construction of maximal concordant subnetwork containing the common reactions of the networks under comparison. Thus, this work can provide general insights in comparing mathematical models of the same or closely-related systems

Estudio de normativas de seguridad en robótica industrial y su aplicación a una estación robotizada de un laboratorio docente

Aquest projecte té la finalitat de tractar el tema de la seguretat en la robòtica industrial. Principalment, es farà la síntesi de la normativa necessària per al disseny del sistema de seguretat del robot SCARA “RH-3FH5515-D1-S15”, que es troba al laboratori de robòtica A5.4 de l'EEBE. Així mateix, es plantejarà un disseny de seguretat fent servir la quantitat més gran de dispositius possibles perquè el sistema compleixi amb dos objectius: El primer objectiu és vetllar per la seguretat de les persones i el segon és servir com a material didàctic perquè els estudiants entenguin millor els conceptes de seguretat industrial. També s'explicarà el procés de programació i muntatge del sistema de seguretat utilitzant els recursos disponibles del laboratori de robòtica. Finalment, aquest treball de fi de grau d'enginyeria electrònica industrial i automàtica s'enfocarà com a guia per a fer futurs treballs referents a la seguretat en la robòtica industrial.El presente proyecto tiene la finalidad de abarcar el tema de la seguridad en la robótica industrial.
