Buchanan and the Social Contract: Coordination Failures and the Atrophy of Property Rights

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT James Buchanan advocated that societies should be based on a social contract. He rejected anarchy, seeing it as a “Hobbesian jungle” that calls for government intervention to maintain social order. He also opposed theories of spontaneous order. These views led to debates about the compatibility of Buchanan's works with classical liberalism and

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without

Joint Radar Jamming and Communication System Design Based on Universal Filtered Multicarrier Chirp Waveform

open access: yesRemote Sensing
In this article, we propose a joint waveform based on universal filtered multicarrier (UFMC) chirp for radar jamming and communication joint systems. Modulation of radar jamming chirp signals and communication signals on different subcarrier groups in ...

“I'm a Good Guy Who Deserves Better, Yet Nobody Wants to Give me Better”: The Accounts of Nice Guys

open access: yesSymbolic Interaction, EarlyView.
Within Western popular culture and online discourse, a “Nice Guy” is someone who enacts niceness for which they believe they are owed, deserving of, or entitled to something in return—especially the romantic or sexual attention of women. In this study, we examine the use of accounts in personal narratives told in an anonymous online discussion forum ...

William E. Walling and the Pragmatist Foundations of Proto‐Western Marxism: A Re‐Evaluation and Critique

open access: yesConstellations, EarlyView.
ABSTRACT This article reevaluates Walling as a neglected precursor to American Western Marxism, arguing that his 1912–1914 trilogy synthesized Marxist theory of his time and Deweyan pragmatism into a distinct “pragmatist conception of history.” Born into “aristocracy” yet radicalized, Walling's unique trajectory—as a co‐founder of the NAACP and critic ...
