Support for restricting civil rights remains a central concern in psychological science. Among these rights, access to information has increasingly been regulated, including through policies limiting adolescents' use of social media. Yet little is known about how adolescents themselves evaluate such measures or how ideological dispositions structure their support. Drawing on research linking Right-Wing Authoritarianism (RWA) to endorsement of restrictive policies, the present study examined whether RWA and age predict support for a new Brazilian law that prohibits unsupervised social media use for individuals under 16 (the so-called Felca Law). A sample of 308 Brazilian adolescents (ages 11–19; 48.4% female) completed measures of RWA and support for the Felca Law. Higher RWA and older age independently predicted greater support for the law, with no significant interaction between them. These findings indicate that authoritarian ideological dispositions operate during adolescence and extend to contemporary digital regulation. Support for the Felca Law appears to be shaped less by developmental maturation than by stable ideological mechanisms, even in a policy domain framed around youth protection.
Rare-Earth-Magnesium(RE-Mg)-based hydrogen storage alloys exhibit high hydrogen capacity and low material cost, while their hydrogen storage behavior is governed by the interplay between thermodynamic stability and kinetic characteristics. Among the relevant thermodynamic parameters, formation enthalpy (ΔH) provides an important descriptor for evaluating hydride stability and hydrogen storage feasibility. This review examines the formation-enthalpy characteristics of RE-Mg systems, with particular emphasis on the extended Miedema model for estimating alloy formation enthalpy and its application to multicomponent compositions. Different approaches for determining ΔH are compared, including theoretical calculations and experimental measurements, and their relationships with phase transformations and hydrogen absorption/desorption thermodynamics are discussed. The role of hydride formation enthalpy in microstructural regulation is further examined, with emphasis on complex surface hydrides involving amorphous, nanocrystalline/metastable, and multiphase structures. The effects of elemental composition, phase constitution, interfaces, and chemical states on thermodynamic and kinetic behavior are discussed. Based on these considerations, strategies for improving the hydrogen storage properties of RE-Mg alloys through compositional, microstructural, and interface regulation are summarized. The potential of machine learning and multiscale approaches for describing multicomponent and multiphase systems is also discussed. Overall, this review establishes a framework linking formation enthalpy with phase structure, microstructure, and hydrogen storage behavior, providing a basis for understanding and designing RE-Mg-based hydrogen storage materials with appropriate thermodynamic stability and improved absorption/desorption characteristics.
Covering: January to the end of December 2024This review covers the literature published in 2024 for marine natural products (MNPs), with 617 citations (578 for the period January to December 2024) referring to compounds isolated from marine microorganisms and phytoplankton, green, brown and red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, the submerged parts of mangroves and other intertidal plants. The emphasis is on new compounds (1256 in 336 papers for 2024), together with the relevant biological activities, source organisms and country of origin. Pertinent reviews, biosynthetic studies, first syntheses, and syntheses that led to the revision of structures or stereochemistries, have been included. An analysis of the role of artificial intelligence in marine natural products research is discussed.
Climate change and rising global temperatures are significantly affecting energy consumption patterns and carbon emissions. This study directly contributes to the United Nations Sustainable Development Goals (SDGs), particularly SDG 13 (Climate Action), SDG 7 (Affordable and Clean Energy), and SDG 12 (Responsible Consumption and Production). This study investigates the relationship between temperature and energy-related emissions from coal, diesel, electricity, and natural gas using panel data from eight Chinese provinces covering the period 1990-2022. Advanced econometric techniques including Panel Autoregressive Distributed Lag (ARDL), Panel Generalized Method of Moments (GMM), Panel Least Squares (PLS), and Panel Quantile Regression (PQR) are employed to analyze the temperature-emission dynamics. The ARDL long-term results indicate a significant and positive relationship between temperature and electricity-driven emissions, while a negative association is observed for coal- and diesel-driven emissions. However, natural gas-driven emissions exhibit more complex behavior, showing a negative long-term relationship with temperature but a positive short-term effect. The ARDL findings are consistent with the results obtained from GMM, PLS, and PQR models, and this consistency strengthens the reliability and robustness of the results. The findings suggest that although fossil fuel consumption is a major driver of rising temperatures, temperature alone does not lead to immediate changes in energy consumption patterns. The study underscores the need for robust policy measures aimed at promoting energy efficiency, accelerating the transition to renewable energy, and developing climate-resilient energy systems to mitigate the impact of rising global temperatures on energy demand and emissions.
