Original Electoral contests over voter beliefs
Dan Alexander, Alexander Evert
Abstract
Abstract Voter perceptions of candidates are the substrate on which campaigns act. It is costly, however, for voters to devote enough attention to politics to change their own perceptions of candidates. This paper views campaigns—and the time, effort, and money they expend—as subsidizing rationally inattentive voters' adoption of new beliefs about candidate platforms. We employ an all‐pay contest to model costly competition over voter perceptions. In our baseline model, campaigns seek to improve perceptions of their own candidates. In a variant, candidates engage in negative campaigning. Among other results, we observe platform divergence under more reasonable informational assumptions than previous spatial models, replacing candidate uncertainty about voters with voter uncertainty about candidates. This model serves as a bridge between behavioral research on campaigns and theoretical literature on elections, offering a richer set of empirical predictions while preserving the insights of the canonical Downsian framework as a limiting case.

Original Striking multiple balances in cross-sector collaborations: how leaders navigate institutional complexity with interdependent leadership behaviors
Sandra Henninger, Rick Vogel
Abstract
Abstract In cross-sector collaborations, leaders must navigate the complex and often conflicting demands of the public, business, and nonprofit sectors. This study explores how leaders manage this institutional complexity through a multilevel framework, drawing on a case study of a tri-sector partnership developing technology for disaster management. Based on evidence from 27 interviews, observations, and documentary material, we identify the leadership repertoire and, as our core contribution, uncover four distinct types of interdependencies between these behaviors: enabling, substituting, stabilizing, and inhibiting. Our findings reveal that leadership in cross-sector collaborations goes beyond adopting a single style; rather, it requires a strategic orchestration of how different behaviors interact. We identify two overarching strategies (selective targeting and sequential switching) that leaders use to combine complementary behaviors while preventing them from undermining each other. By focusing on leaders’ microlevel agency in response to macrolevel sector differences, this study provides a clearer understanding of how interdependent leadership behaviors converge into what we theorize as institutional leadership in CSCs.

JCC — pp. 1-16 2026-07-17 Original China’s UN Diplomacy on the Russo-Ukrainian War
Vita Golod, Nataliia Mudrenko
Abstract
This article examines how China conducts its diplomacy on Ukraine within the United Nations framework and assesses whether its stated principles align with its actual behavior. Using corpus linguistics, discourse analysis, and UN voting data from 2014 to 2025 across the United Nation Security Council (UNSC), General Assembly (UNGA), and selected UN technical bodies, it analyzes the relationship between China’s words and its deeds. A comparison with the Palestine/Gaza corpus shows that China applies more attribution and selective framing, challenging the notion of a uniform ‘principled neutrality’. The findings show that China’s abstention doctrine is conditional, and that its UN behavior reflects strategic differentiation across political and technical arenas of global governance.
