Alfred Russel Wallace Notes 35. Natural Selection By Evolution., Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823?1913) is remembered, with Charles Darwin, as the co-originator of the concept of evolution by natural selection. But Wallace’s framing of the idea increasingly became one in which natural selection itself was regarded as a law of nature, not a theory per se.

Alfred Russel Wallace Notes 34. Did Alfred Russel Wallace’S Chief Assistant From His Expedition To The Malay Archipelago Really Name Himself Ali Wallace?, George Beccaloni, Charles H. Smith Editor

Faculty/Staff Personal Papers

In 1907, Thomas Barbour met Alfred Russel Wallace’s former chief assistant Ali on Ternate Island, Indonesia. Ali apparently told him that he had adopted “Wallace” as his second name. This claim has been questioned by historian John van Wyhe and anthropologist Gerrell Drawhorn, probably because it appeared unprecedented. However, this was not an isolated example; in 1872, John Thomas Cockerell recorded that a man from the Aru Islands, Indonesia, employed by Wallace in 1857, along with his eldest son, had similarly adopted “Wallace” as part of their personal names.

Cerebral Vascular Response During A Hypercapnic Challenge With And Without Simultaneous Activation Of The Sympathetic Nervous System, Sajjad Moradi, James E. Brown, John Kolade, Hannah E. Nagib, R Matthew Brothers

International Journal of Exercise Science: Conference Proceedings

Cerebral vascular function/health is crucial for the maintenance of neurocognitive function and prevention of various neurocognitive and cerebral vascular conditions/diseases. Cerebral vascular function is commonly assessed by evaluating the vasodilatory response to a hypercapnic stimuli. A larger vasodilatory response is associated with more positive outcomes, while a blunted response is associated with an increased risk of cerebral vascular and neurocognitive diseases in the future. However, it remains unclear whether simultaneous activation of the sympathetic nervous system (SNS) can attenuate cerebral vasodilation during a hypercapnic challenge. PURPOSE: Therefore, this study tested the hypothesis that cerebral vascular vasodilatory responsiveness to a …
