Signal And Substance: Why Methodological Sophistication Fails To Guarantee Inference, Aamir Rashid, Rizwana Rasheed Jul 2026

Signal And Substance: Why Methodological Sophistication Fails To Guarantee Inference, Aamir Rashid, Rizwana Rasheed

Publications and Research

Despite increasing analytical sophistication, empirical research in organization studies continues to suffer from fragile inference, uneven theoretical accumulation, and contested credibility. This paper seeks to explain why these problems persist by shifting attention from authors’ methodological choices to the evaluative dynamics of peer review. Adopting a conceptual and theory-analytic approach, the paper theorizes peer review as an inferential gatekeeping system. Drawing on research design, theory evaluation, and philosophy-of-science literatures, this study develops an analytical framework to examine how evaluative routines shape what constitutes empirical rigor during the review process. The analysis identifies five recurring reviewer blind spots: inferential scope inflation, …

Problems And Possibilities Of Continuous Forage Production In Arid Subtropical Regions, Horst Patzold Jul 2026

Problems And Possibilities Of Continuous Forage Production In Arid Subtropical Regions, Horst Patzold

IGC Proceedings (1977-2023)

The low animal performance and stocking rate in arid subtropical regions mainly depend on the discontinuity of forage production. In winter-raining steppes of North Africa, the cultivation or sod-seeding of adapted grasses, especially for forage production in the dry season. (summer), is recommended. For the dry savannas of West Africa with summer­raining, proposals are made for three different stages depending on the intensity of land use. They include a better use of grazing areas by transhumance, proposals for a ranching system, especially for meat production, and possibil­ities for milk production by stabling of cattle, including forage production under irrigation.

Optimal Combinations Off Our Large Herbivores For Short Grass Prairie, George M. Van Dyne Jul 2026

Optimal Combinations Off Our Large Herbivores For Short Grass Prairie, George M. Van Dyne

IGC Proceedings (1977-2023)

Diets of four large herbivores grazing together on a shortgrass prairie rangeland were studied. Cattle and bison consumed mainly grasses; sheep and antelope consumed mainly forbs. To maximize forage use, optimal grazing deter­mined by nonlinear programming would be 67, 20, 12, and I% of the forage grazed to be taken by cattle, bison, sheep, and antelope, respectively. Historically, this range has been grazed primarily by cattle. This study suggests more animal production could be attained with a mixture of herbivore species.
