The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

The “We” and “Me” of Identity in Hazardous Industry Organizations: Face Work Tactics Among Practicing Engineers

open access: yesSymbolic Interaction, EarlyView.
In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

Monitoring active osprey nests with drones is more time efficient and less disturbing than conventional methods

open access: yesWildlife Biology, EarlyView.
Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

open access: yesWildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Delisting the Northern Rocky Mountain gray wolf from the US Endangered Species Act: an assessment of political discourse over 20 years

open access: yesWildlife Biology, EarlyView.
Feared, revered, and politicized, wolves have long captured human imagination, and ignited fierce conservation conflicts. In the United States, the Endangered Species Act protects species at risk of extinction from human impacts. This far‐reaching legislation, which impacts development and state‐level wildlife management, has been fraught with legal ...
