The Legacies of Lockdown: Moral Logics of Exchange and Mistrust in Postpandemic China

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT When Shanghai entered an extended lockdown under China's Zero‐COVID policy in spring 2022, residents found themselves confined within their residential compounds, cut off from conventional supply chains, and dependent on improvised systems of local provisioning and state rationing. From the perspective of economic anthropology, such conditions

MO/PVDF‐HFP Electrospun Nanofiber‐Based Triboelectric Nanogenerator for Mechanical Energy Harvesting and Boundary Security Sensing

open access: yesSmall, EarlyView.
Magnesium oxide (MgO (MO)) nanoparticles (NPs) were synthesized via a hydrothermal process and MO/PVDF‐HFPnanofiber film‐based triboelectric nanogenerators (TENG) were fabricated by incorporating various concentrations of MO NPs into the PVDF‐HFP polymer via the electrospinning process..

Multidirectional load-carrying capacity of cross-laminated timber panel-to-panel orthogonal joint using self-tapping screws installed at an angle subjected to combined load

open access: yesJournal of Wood Science
This study elaborated on the potential effects of monotonic loading on a cross-laminated timber (CLT) panel-to-panel orthogonal joint. The joint was subjected to multidirectional loading at various angles when it was connected using the self-tapping ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Accommodating Women: Geographies of Citizenship in the Twentieth‐Century Campaign for Women's Jury Rights

open access: yesGender &History, EarlyView.
ABSTRACT Australian women were among the first in the world to receive electoral suffrage, yet it took until 1997 before they had full equality of jury suffrage. This article examines the debate around female jurors by focusing less on discourses of citizenship than on the subterranean spatial arrangements upon which equality depended.

An Experimental and Analytical Method for Investigating Plastic Flow in Form Tapping [PDF]

open access: yes, 2006
While threaded holes made by cutting taps result in material removal, in form tapping, the tap displaces the work material by plastic flow to form the thread section.
