Abstract

fetched live from OpenAlex

ANY HIKER YOU MEET IN THE BROOKS RANGE of Alaska if he or she has heard about Bob Marshall, and I am sure you will be amazed how well known this name is.His writing inspired many people, set a standard for conservation in northern Alaska, and ultimately led to the establishment of Gates of the Arctic National Park and Preserve, an eight-million-acre wilderness in the central Brooks Range of Alaska.The man later known as a great conservationist and wilderness advocate, Bob Marshall, was born in 1901.As the son of activist lawyer Louis Marshall, he inherited from his father the urge to stand for what he believed in, be it civil rights or wilderness protection (for a comprehensive tale of Bob Marshall's life, see Glover, 1986).Bob grew up hiking in the Adirondack Mountains, where he developed a special sense for untamed places and the desire to keep them unspoiled.He chose forestry as a profession.In 1930 he came to Alaska for the first time and spent a winter in Wiseman, a small community on the southern slope of the Brooks Range.Back on the East Coast in 1931, he began to write about wilderness issues, deforestation, and conservation.In 1933 he became director of the division of forestry in the Bureau of Indian Affairs.In 1935, Marshall was among the principal founders of the Wilderness Society.Others included Aldo Leopold and Benton MacKaye, who helped establish the Appalachian Trail.Bob Marshall's plot in Barrenland Creek, Brooks Range, Alaska, with members of the expedition.Left to right: Joerg Sommer, Martin Wilmking, and Jens Ibendorf.No seeds sprouted and survived from Marshall's planting in 1939, but two seedlings planted by Sam Wright in 1968 are alive and show recent growth on their tips.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
