    (2024) Juan-Ramón Cuadros-Muñoz; Juan Antonio Jimber del Río; Rafael Sorhegui-Ortega; Michelle Zea-De la Torre; Arnaldo Vergara-Romero
    An econometric model was developed to analyze the contribution of various factors to the gross value added to the agricultural, manufacturing, and service sectors in the United States. The study found that variables such as rare earth element mining, the employment it generates, the domestic consumption, imports, and prices of certain elements significantly impact economic sectors. The models showed a good fit and met the necessary statistical assumptions. Rare earth elements are essential for a wide range of technological products, with China being the leading producer and consumer. This has raised concerns about the dependence on other countries. These elements significantly impact the economy’s primary, secondary, and tertiary sectors used in agriculture, manufacturing, and services. Rare earth elements’ mining and processing are complex and expensive processes, and demand is expected to continue to increase in the future.

    (Multidisciplinary Digital Publishing Institute, 2024) Mohamed Al Hammadi; Juan Antonio Jimber del Río; María-Salomé Ochoa-Rico; Orlando Arencibia Montero; Arnaldo Vergara-Romero
    Financial technology (fintech) innovations are transforming banking globally. Their adoption poses new opportunities and risks for Islamic banks with unique requirements. This study examines fintech’s implications for risk management effectiveness in United Arab Emirates Islamic banks. A conceptual model incorporates factors like fintech adoption, emerging capabilities, digital maturity, and IT security influencing outcomes. Primary data were collected via survey from nine UAE Islamic banks and analyzed using PLS-SEM. Results show that fintech adoption and capabilities positively impacted effectiveness, while digital transformation alone did not. The findings also show that the regulatory environment did not moderate relationships as hypothesized. The findings provide empirical evidence on optimizing risk management through responsible fintech enablement and oversight alignment in the UAE context.
