Alfred Russel Wallace Notes 38. Alfred Russel Wallace's "Revolt Of Democracy": A Critical Analysis Of Early 20th Century Labor Theory And Its Contemporary Relevance, James Williams, Charles H. Smith Editor
Faculty/Staff Personal Papers
This article examines Alfred Russel Wallace’s political treatise The Revolt of Democracy (1913), analyzing his theoretical framework for addressing labor unrest and economic inequality in early 20th-century Britain. Wallace's work presents a comprehensive critique of competitive capitalism and proposes systematic government intervention to address structural poverty. Through close textual analysis and comparison with contemporary UK labor conditions, this study evaluates the enduring relevance of Wallace's economic theories and policy prescriptions. The analysis reveals significant continuities between early 20th-century and contemporary debates about living wages, government employment standards, and wealth redistribution, while highlighting both the prescience and limitations of Wallace’s analytical …

International Journal of Exercise Science
International Journal of Exercise Science 18(7): 971-983, 2025. The total work completed during an exercise session is often assumed to be the primary factor influencing the kinetics of post-exercise recovery. However, the duration of work and rest periods during high intensity interval training (HIIT) have been shown to impact the magnitude of physiological stress and could also impact post-exercise recovery. The aim of this study was to characterize the recovery time course of neuromuscular function following work-to-rest matched HIIT protocols with different work interval durations and conducted to task failure. Participants (n=12, n=6 females) completed a ramp incremental exercise test …
