Publication Global Digital Analysis for Science Diplomacy(MDPI AG, 2023-11-08) ;Miguel Fuentes ;Juan Pablo Cárdenas ;Gastón Olivares ;Eric Rasmussen ;Soledad Salazar ;Carolina Urbina ;Gerardo VidalDiego LawlerAddressing climate change requires innovative, collective action and robust international collaboration. Through joint efforts, nations can significantly reduce greenhouse gas emissions, pioneer sustainable technologies, and implement effective adaptation measures. Science diplomacy and knowledge sharing hold the potential to bolster global stability and peace by directly confronting climate change challenges. Therefore, it becomes imperative to evaluate a country’s alignment of its scientific knowledge system (SKS) with international guidelines. This study delineates the global scientific discourse on climate change and juxtaposes the alignment between an individual nation’s research endeavors and United Nations resolutions concerning climate change and sustainable development. Our methodology integrates data extraction from scientific research databases with advanced textual analysis tools, highlighting this study’s unique focus on the intersection of climate change and UN resolutions. To deliver an empirical analysis, we leveraged complex network theory and advanced text-processing techniques. Our findings demonstrate the trajectory of global scientific output related to these themes, segmented by countries and coupled with CO2 emissions data, key disciplines, and collaboration networks. These insights are instrumental for leaders, policymakers, and stakeholders, highlighting areas of convergence and divergence in national research initiatives essential for achieving global climate goals. Such knowledge is strategically useful for crafting purpose-driven public policies and honoring enduring multilateral pledges to address the climate crisis proactively. - Some of the metrics are blocked by yourconsent settings
Publication Opinion Polarization during a Dichotomous Electoral Process(Wiley, 2019-01) ;Gastón Olivares Fernández ;J. P. Cárdenas ;J. C. Losada ;J. BorondoDimitrios StamovlasisPolitical polarization can emerge on electoral campaigns where the population faces a dichotomous decision, with only two voting alternatives. In this paper, we analyze the Twitter conversation around the second round of the 2017 Chilean elections, where voters had to choose between the final two candidates. First, we have estimated the opinions of Twitter users obtaining a distribution of opinions for each day. Next, we have measured the resulting political polarization from the cited opinion distributions and track its evolution during a full week that includes the voting day. We found the conversation to be highly polarized, reaching its maximum during the previous day to the election and significantly decreasing the day after due to the presence of new users who only participated during that day.
