Disciplining the “Queen of the World”? Responsible Innovation as a Way of Life
Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT This paper offers a critical reflection on the concept of responsible innovation as defined during the last decades. We argue that the emphasis on innovation as a process risks neglecting the very goals of innovation, namely societal desirability and acceptability. Thus, we suggest reconsidering the role of imagination, the “Queen of the world”

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway
Boreas, EarlyView.The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

Comparative review of entanglement risk assessments for cetacean conservation and management
Conservation Biology, EarlyView.Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Study on the Nonlinear Vibration Characteristic of Bending-torsional Coupled Single-stage Gear
Jixie chuandong, 2019 Taking spur gear pair as the research object, a 6-DOF coupled bending-torsion nonlinear vibration model including time-varying meshing stiffness, comprehensive error, backlash and input torque is established. Based on the bifurcation diagram and Poincare

Research on the Influence of Backlash on Mesh Stiffness and the Nonlinear Dynamics of Spur Gears
Applied Sciences, 2019 In light of ignoring the effect of backlash on mesh stiffness in existing gear dynamic theory, a precise profile equation was established based on the generating processing principle. An improved potential energy method was proposed to calculate the mesh

Dimensional Chain and Dynamics Analysis of the Gear System with Backlash based on CETOL
Jixie chuandong, 2015 By using the 3- Dimension tolerance analysis software CETOL 6σ,taking the gear backlash in the gear system as closed- loop,considering the actual assembly sequence and the standard normal distribution of the processing size of each part,the 3D dimension ...

Fisheries Management and Ecology, EarlyView.ABSTRACT In fisheries management, socioeconomic data, specifically qualitative data analysis, is often underutilized. This study qualitatively analyzed a primary federal data collection effort in the Northeast United States, The Greater Atlantic Region Commercial Fishing Business Cost Survey.

The Howard Journal of Crime and Justice, EarlyView.ABSTRACT The cultures and governance of security markets in the United Kingdom are often characterised through a paradoxical narrative of simultaneous state retreat and progressive advance. In the face of repeated recent high‐profile security failures, and global changes in material political economy, we argue that UK security governance is adapting to
