Propuesta e implementación de una intervención educativa para el abordaje de la biotecnología desde la controversia sociocientífica
Get PDFEl desarrollo de la biotecnología moderna en las últimas décadas ha desempeñado un
papel fundamental en diversas áreas como la medicina, la agricultura o la industria. Sin
embargo, este auge no ha estado exento de polémicas en diversos sectores de la sociedad,
confiriendo a la biotecnología un papel destacado entre las denominadas controversias
sociocientíficas: problemáticas sociales de raíz científica que también abarcan otros
aspectos éticos, políticos, medioambientales y sociales. En este contexto, resulta
fundamental la alfabetización científica —competencia STEM en la legislación educativa
vigente— para comprender la base científica subyacente y evaluar las implicaciones de
estas controversias.
El objetivo principal de este Trabajo Final de Máster (TFM) ha sido presentar una
propuesta didáctica innovadora para el alumnado de 4º de ESO que ofrezca a los
estudiantes un escenario en el cual puedan enfrentarse a las controversias sociocientíficas
en el ámbito de la biotecnología desde la reflexión crítica, permitiendo así el desarrollo
de habilidades y competencias necesarias para una ciudadanía informada y participativa.
La propuesta, la cual integra elementos del Aprendizaje Basado en Proyectos junto con el
uso de noticias reales y las tecnologías de la información y comunicación, se ha
implementado durante el transcurso de las prácticas, con una evaluación favorable por
parte del alumnado.The progress of biotechnology over the past few decades has played a crucial role in
multiple fields such as medicine, agriculture and industry. However, this development has
always been surrounded by controversy in diverse sectors of society, granting
biotechnology a prominent position among the socioscientific issues: social controversies
presenting a scientific foundation that comprise other ethical, political, environmental and
social concerns. In such context, scientific literacy —STEM competence in the current
educational legislation— becomes essential in order to understand the underlying
scientific framework and evaluate the implications of these controversies in other areas.
The main goal of this work has been to present an innovative educational proposal for 4th
graders of secondary education that provides students with a scenario to engage with
socioscientific issues in the field of biotechnology from a critical perspective, thus
enabling the development of the necessary skills for an informed and participatory
citizenship. The proposal, which integrates elements of Project-Based Learning along
with the use of real news and information and communication technologies, has been
implemented during the course of the practicum, receiving positive feedback from the
students

Electric Field Effects on Curved Graphene Quantum Dots
Get PDFThe recent and continuous research on graphene-based systems has opened their usage to a wide range of applications due to their exotic properties. In this paper, we have studied the effects of an electric field on curved graphene nanoflakes, employing the Density Functional Theory. Both mechanical and electronic analyses of the system have been made through its curvature energy, dipolar moment, and quantum regeneration times, with the intensity and direction of a perpendicular electric field and flake curvature as parameters. A stabilisation of non-planar geometries has been observed, as well as opposite behaviours for both classical and revival times with respect to the direction of the external field. Our results show that it is possible to modify regeneration times using curvature and electric fields at the same time. This fine control in regeneration times could allow for the study of new phenomena on graphene.This work was supported by the Regional Government of Castilla y León (Junta de Castilla y León), by the Ministry of Science and Innovation MICIN (grant PGC2018-097831-B-I00), and by the European Union NextGenerationEU (PRTR C17.I1)
The Boomerang Effect of Suppression of Emotional Expression: Relationship Power, Affectivity and Adolescent and Youth Male-To-Female Dating Violence
Get PDFScarce research has been performed on the role of power, affectivity, and suppression of emotional expression in the use of dating violence by adolescents and young men. This study aims to analyze a model of the associations between perceived power (control and dominance), affectivity (positive and negative affect), suppression of emotional expression and the frequency of use of male-to female dating violence. Participants in this cross-sectional and correlational study were 786 Spanish students aged between 13 and 25 years (M = 18.80; SD = 2.93) divided in two groups: 13–18 (316 adolescents, M = 15.58; SD = 1.02) and 18–25 (462 young men, M = 20.79; SD = 1.98) with 8 participants not stating their age. Different sequential mediation models confirmed that, only in young men, affectivity (negative and positive affect) and suppression of emotional expression mediate the relationship between power and the use of dating violence. Fostering equal relationships, associating them with positive emotional states, avoiding the frustration derived from low power perception, and providing young men with strategies for appropriately expressing their emotions may help decrease the use of dating violence.This work is supported by a grant awarded to the iR&D project PID2020-116658GB-I00PSI, financed by MCIN/ AEI/10.13039/501100011033/.

Evaluation of uncertainty in the measurement of the stress-optic coefficient
Get PDFIn this study, a method for evaluating the uncertainty of stress-optic coefficient measurements of photoelastic materials on a uniaxial tension/compression specimen is presented. The same problem is also approached in other previously used methods, in which multiple data fitted with ordinary least squares are considered. However, only the repeatability contribution to uncertainty is considered in those other methods, which are therefore not consistent with the ISO–Guide to the expression of Uncertainty in Measurement. All possible contributions to uncertainty can be taken into account using the General Least Squares-Lagrange Multipliers (GLS-LM) method presented here. The application of the method is illustrated with an example, from which it can be seen that uncertainty has been underestimated in the other methods used to date. As well as the estimate of the stress-optic coefficient and its corresponding standard uncertainty, the method also provides a data consistency test and an outlier identification tool
Single and multispecies microalgae toxicological tests assessing the impact of several BPA analogues used by industry
Get PDFBPA is a hazard for human and environmental health and recently BPA was added to the Candidate List of substances of very high concern by European Chemical Agency (ECHA). In accordance with this proposal, the authorities have encouraged the replacement of BPA by BPA analogues; however, little is known about the impact of these compounds on the environment. Due to this situation five BPA analogues (BPS, BPAP, BPAF, BPFL and BPC) were chosen in order to study their effects on marine primary producers. Three marine microalgae species (Phaeodactylum tricornutum, Tetraselmis suecica and Nannochloropsis gaditana) were selected for single and multispecies tests concerning the ecotoxicological effects of these BPA analogues. Microalgae were exposed to BPs over 72 h at different dosages (5, 20, 40, 80, 150 and 300 μM). Responses such as: growth, ROS production, cell complexity, cell size, autofluorescence of chlorophyll a, effective quantum yield of PSII and pigment concentrations were assessed at 24, 48 and 72 h. The results revealed that BPS and BPA showed lower toxicity to microalgae in comparison with BPFL > BPAF > BPAP and >BPC for the endpoints studied. N. gaditana was the least sensitive microalgae in comparison to P. tricornutum and T. suecica. However, a different trend was found in the multispecies tests where T. suecica dominated the microalgae community in relation to N. gaditana and P. tricornutum. The results of this work revealed for first time that present day BPA analogues are a threat and not a safe substitute for BPA in terms of the marine phytoplanktonic community. Therefore, the results of their impact on aquatic organisms should be shared.Marta Sendra thanks to the Juan de la Cierva Incorporación (IJC 2020-043162-I) contract funded by MCIN/AEI/10.13039/501100011033, European Union NextGenerationEU/PRTR
