Commoning in dynamic environments: community-based management of turtle nesting sites on the lower Amazon floodplain

open access: yesEcology and Society, 2018
Community-based natural resource management (CBNRM) involves a system of local practices designed to regulate access to, and use of, natural resources through rules and norms shared by a set of users.

Vernal Pool Conservation: Enhancing Existing Regulation Through the Creation of the Maine Vernal Pool Special Area Management Plan [PDF]

open access: yes, 2019
Conservation of natural resources is challenging given the competing economic and ecological goals humans have for landscapes. Vernal pools in the northeastern US are seasonal, small wetlands that provide critical breeding habitat for amphibians and ...

Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

The influence of working memory load on response inhibition in children with attention-deficit/hyperactivity disorder or reading disorder [PDF]

open access: yes, 2011
The aim of the present study was to examine the relationship between response inhibition and working memory in 8-12-year-old children with attention-deficit/hyperactivity disorder (ADHD; n = 19), reading disorder (RD; n = 17), ADHD + RD (n = 21), and ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Technology-dependent commons: The example of frequency spectrum for broadcasting in Europe in the 1920s

open access: yesInternational Journal of the Commons, 2011
The aim of this paper is to test the design principles, identified as crucial for institutions governing long enduring common pool resources, on the use of the electromagnetic spectrum, a peculiar resource in many respects.

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Cultural norms, cooperation, and communication: Taking experiments to the field in indigenous communities

open access: yesInternational Journal of the Commons, 2013
Extensive experimental research has been devoted to the study of behaviour in laboratory settings related to public goods, common-pool resources, and other social dilemmas.

Regulation and Evolution of Compliance in Common Pool Resources [PDF]

open access: yes
The paper jointly models the evolution of compliance with regulation and the evolution of a CPR stock, by combining replicator dynamics describing compliance with harvesting rules, with resource stock dynamics.
