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

Symbolic 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

The creation of T-shaped gate for low noise field effect UHF transistors

Технологія та конструювання в електронній апаратурі, 2006
The process of forming T-shaped gates in low-noise field-effect transistors for millimeter and submillimeter wavelength ranges has been investigated. A technological scheme for gate formation is proposed, based on electron-beam exposure of a three-layer ...

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

Geostandards and Geoanalytical Research, EarlyView.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Striking for a Just Transition? North American Auto Unions and the Electric Vehicle Transition

Industrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT Decarbonization heightens risks for workers, but union strategies shape how these risks are managed and whether new jobs offer quality employment. This paper compares U.S. and Canadian auto unions during the 2023 Detroit Three bargaining, focusing on strategic capacities and internal politics to explain their divergent responses to the EV ...

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...
