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

Toward Explainable Engineering Decisions: Pursuing a Descriptive Decision Theory at the Intersection of Analysis, Judgment, and Conviction

Systems Engineering, EarlyView.
ABSTRACT Engineers design the technical systems that define and sustain our society. The decision‐making scenarios they face require both quantitative analyses and the consideration of qualitative factors, which are shaped by deeply held beliefs, values, and societal contexts. However, existing engineering decision‐making models, primarily derived from

Cold solid propellant motor has stop-restart capability [PDF]

, 1966
Solid propellant rocket is kept and fired at low temperatures in launch vehicles or spacecraft. The motor is capable of developing a specific impulse comparable to that of liquid propellant motors, is started, stopped, and restarted, and is stored in ...

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting

Wildlife Biology, EarlyView.
Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...
