    In this paper we explore whether countries led by women have fared better during the COVID-19 pandemic than those led by men. Media and public health officials have lauded the perceived gender-related influence on policies and strategies for reducing the deleterious effects of the pandemic. We examine this proposition by analyzing COVID-19-related deaths globally across countries led by men and women. While we find some limited support for lower reported fatality rates in countries led by women, they are not statistically significant. Country cultural values offer more substantive explanation for COVID-19 outcomes. We offer several potential explanations for the pervasive perception that countries led by women have fared better during the pandemic, including data selection bias and Western media bias that amplified the successes of women leaders in OECD countries

    Global urban environmental change drives adaptation in white clover

    Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale

    Seeing the Forest and the Trees: AI Bias, Political Relativity, and the Language of International Relations

    Biases in machine learning (ML) and artificial intelligence (AI) are well known, namely that AI systems learn bias from word embeddings and replicate human-like biases such as gender and racial/ethnic stereotypes. In international politics, biases in AI can generate erroneous and inaccurate forecasting models that miss critical events such as the Arab Spring, or get the direction or magnitude of predictions wrong. Event data is a particular genre of political data that reports and encodes the actions and relationships between actors in the international system, including countries, NGOs, individuals, and groups of people. Event data sets represent a significant conceptual, technological, and financial investment and are used to inform government policy decisions, but its algorithms ignore temporal and linguistic nuances that bias event code generation and political forecasting models. This chapter will focus on the theoretical foundations of bias in AI for international relations research, examining how political events are described and encoded differently depending on the source and perspective of the source, language, and culture of the author

    Online social cohesion reflects real-world group action in Syria during the Arab Spring

    No full text
    In recent years, political activists have taken to social media platforms to rapidly reach broad audiences. Despite the prevalence of micro-blogging in these sociopolitical movements, the degree to which virtual mobilization reflects or drives real-world movements is unclear. Here, we explore the dynamics of real-world events and Twitter social cohesion in Syria during the Arab Spring. Using the nonlinear methods cross-recurrence quantification analysis and windowed cross-recurrence quantification analysis, we investigate if frequency of events of different intensities are coupled with social cohesion found in Syrian tweets. Results indicate that online social cohesion is coupled with the counts of all, positive, and negative events each day but shows a decreased connection to negative events when outwardly directed events (i.e., source events) were considered. We conclude with a discussion of implications and applications of nonlinear methods in political science research

    Grant Writing and the Hidden Curriculum: Mentoring and Collaborating Across Disciplines

    Submitting grant proposals is becoming an increasingly common expectation - and, in some cases, a requirement - in the discipline of political science as well as other social sciences and the humanities. However, writing a grant with a good chance of success at getting funded is not part of standard mentorship or pedagogy in our discipline. It is a part of the hidden curriculum, where grant-writing skills often are taught informally in working with a principal investigator. This article describes the process and structure of writing a grant to provide a roadmap for scholars to follow in submitting externally funded projects. The article describes an Institutional Review Board-approved survey about mentorship and grant writing and discusses the importance of socialization, professionalization, and administration in supporting scholars in writing and obtaining grants

    Populism and Popular Support: Vertical Accountability, Exogenous Events, and Leader Discourse in Venezuela

    No full text
    As a populist leader, Hugo Chavez famously used emotionally charged populist rhetoric to appeal to a broad base of poor and working-class Venezuelans. Was his choice of linguistic discourse a tool of popular control, response to public opinion, or both? Answering this question sheds light on the effectiveness of classical democratic conceptions of vertical accountability for populist leaders. Using a theoretical framework incorporating macro implications of Zaller’s receive-accept-sample (RAS) model, the concept of Erikson, Mackuen, and Stimson’s mood, and latent public opinion, we develop several competing expectations regarding rhetoric and presidential approval in Venezuela. Using computational sentiment analysis on a unique dataset of transcripts from Chavez’s Aló Presidente broadcasts, we evaluate Chavez’s quarterly public approval ratings with vector autoregression (VAR) and Koyck models. Results indicate presidential approval levels are causally linked to not only exogenous economic factors but also leader discourse. Results also indicate that leader language is not shaped by approval levels, illustrating the power of messaging and media control for populist leaders and the potential limits of democratic accountability

    Best Practices for Normalizing Parents in the Academy: Higher- And Lower-Order Processes and Women and Parents\u27 Success

    Our research on bias in family formation is rooted in the extant literature of gender and academia but moves beyond discussion of the leaky-pipeline metaphor to explore less frequently addressed issues including pregnancy loss, illness, lactation, and challenges faced by academic parents who are the partners of those who have given birth. We explore the lower-order processes that inform the gap in professional achievement between men and women in political science specifically and in academia more broadly. In turn, these lower-order processes manifest as more observable higher-order outcomes such as the disparate rates of tenure and promotion. We conducted a 100-question survey from November 2017 through July 2019 involving more than 300 respondents. Through analysis of open-ended survey responses, we identified a common theme uniting faculty experiences at a range of universities: family formation and parenting can be isolating processes for academics, and there often is a gross lack of both formal and informal support within universities, which creates the potential for setbacks in both personal and professional life. We highlight the challenges confronting academic parents - especially women - and suggest potential avenues to a more inclusive and balanced approach to academia

    Women and Minorities Encouraged to Apply (Not Stay)

    The Coronavirus 2019 (COVID-19) pandemic has deepened gender and racial diversity problems in academia. Mentorship shows women and other under-represented groups where the ladders to success are, and helps them avoid the chutes, a revised leaky pipeline metaphor. Here, we identify tangible strategies that will improve gender equity, including increasing active mentorship by male academics
