Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Democracy and Development: The Role of Outside-of-School Experiences in Preparing Young People to Be Active Citizens

open access: yes, 2011
Public schools historically have been the primary institution responsible for preparing young people for participation in a democratic society. However, the almost exclusive focus by today’s schools on knowledge and skills hinders their ability to be ...

Do Politics in Our Democracy Prevent Schooling for Our Democracy? Civic Education in Highly Partisan Times

open access: yes, 2021
Amid hyper-partisanship, increasing critiques of civic education reform priorities from conservatives, and growing signs of democratic backsliding, can schools provide foundational support for democratic norms, commitments, and capacities?

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

The epistemology of democracy: The epistemic virtues of democracy

open access: yesFilozofija i drustvo, 2020
The new and vibrant field of the epistemology of democracy, or the inquiry about the epistemic justification of democracy as a social system of procedures, institutions, and practices, as a cross-disciplinary endeavour, necessarily encounters both epistemologists and political philosophers.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Reading Democracy and Education in the Context of World War I

open access: yes, 2017
In this historical study, the author offers a reading of Dewey’s Democracy and Education in the context of the two other books Dewey published the year before, German Philosophy and Politics and his coauthored Schools of To-morrow. Having published three

BIPOC Community Perspectives on Environmental Justice in Georgia

open access: yesJournal of Community Engagement and Scholarship
For decades, the environmental and climate justice spaces have been predominantly spearheaded by white activists and institutions, even as Black, Brown, and immigrant communities experience the brunt of climate change’s impact. The resulting exclusion of

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.
