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 ...

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 ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Development of a correction unit based on fuzzy logic for the control system of the load movement mechanism of an overhead crane

open access: yesPower engineering: research, equipment, technology
The purpose. Introduction into the bridge movement drive control system of a bridge support movement synchronization unit, developed in stages on the basis of fuzzy logic to eliminate bridge tilt arising as a result of the movement of a flexible suspension load along the bridge by a trolley.Methods. The objectives set in the study were achieved through

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

open access: yesWildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Agricultural Vulnerability Assessment: Climate and Non‐Climate Interactions in Crop Production Systems

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Recent climate phenomena show that Spain is one of the most vulnerable countries to climate change impacts, with varied regional effects from flash floods to drought. This study assesses the vulnerability of four major crops (cereal, rice, grape and olive) in Catalonia to climate change through a comprehensive vulnerability index incorporating
