A Spatial Clustering Approach of Economic Activities: An Application to the Agribusiness Sector in Brazil's Midwest Region

open access: yesGeographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT The spatial distribution of economic activities is central to regional economics. However, empirical tools for comparing industries based on the similarity of their spatial distributions remain limited. Traditional cluster analysis typically ignores geographical distance and connectivity, while spatial methods focus on clustering places rather

Evaluation of the Efficiency of a Biobased Reactive Plasticizer on the Morphology and Properties of Sustainable Flexible Films Based on Poly(Lactic Acid) (PLA) Produced by Blown Film Extrusion

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
A comparative investigation of two epoxy additives derived from cardanol (NC513 and NC514s) for production of films based on poly (lactic acid) (PLA), acetyl tributyl citrate (ATBC), and poly (butylene adipate‐co‐terephthalate) (PBAT) clarified their distinct roles, with NC513 mainly acting as a plasticizer, reducing viscosity and enhancing ductility ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

open access: yesApplied Economic Perspectives and Policy, Volume 48, Issue 4, Page 984-1004, September 2026.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2519-2533, September 2026.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by
