A practical, adaptive compliance management framework for improving marine protected area effectiveness

open access: yesConservation Biology, EarlyView.
Abstract Noncompliance regularly undermines the effectiveness of marine protected areas (MPAs) worldwide. The reasons for and drivers of noncompliance depend on the context (e.g., insufficient funding, capacity, neocolonialism, historical conflict), but the prevalent solution offered to curtail noncompliance tends to be more or better enforcement.

An Angler‐Friendly AI Pipeline for Self‐Reporting and Automatic Catch Analysis in Recreational Fisheries

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Monitoring recreational fisheries is difficult: anglers are widely dispersed, gear and practices vary, and many species are involved, which leads to fragmented and scarce data. To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into standardised records of catch composition and ...

A method for static and dynamic load analysis of standard and modified spur gears [PDF]

open access: yes, 1983
The mesh stiffness and dynamic load characteristics for several cases of the Normal Contract Ratio and High Contact ratio gearing. The considered contact ratios were grouped in the general range of 1.7,2.0, and 2.3.

Identifying Purse Seine Vessel Operations Through Machine Learning Models for Better Spatial Fishing Effort Estimates

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Spatial fisheries management requires precise, spatial explicit information on species distribution and fishing impacts. In the NW Mediterranean, the distribution of small pelagic fish (SPF) stocks is currently assessed through annual acoustic surveys.

miştir. Design of A Two Axis Line of Sight Stabilization System for Vessels

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2017
By preventing the angular vibrations of the platform from being carried on to the axes of the attached imaging or laser systems, line of sight stabilization allows both a stable image to be obtained and a stable marker to be created. In this study, a two

Some alternative dynamic design configurations for large horizontal axis WECS [PDF]

open access: yes
The present U.S. development effort toward large horizontal axis WECS concentrates on the configuration with two rigid blades with collective pitch variation and a yaw gear drive.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

open access: yesJournal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Wind tunnel tests of a blade subjected to midchord torsional oscillation at high subsonic stall flutter conditions [PDF]

open access: yes
A mechanical drive system for oscillating blades in a wind tunnel at frequencies up to 767 hertz and amplitudes of + or - 1.2 deg is described. High-speed motion pictures of schlieren images of the flow over a double-circular arc blade oscillating in ...

How Alternative Management Ideas Are Realized for the Public Good: Performative Fabrics of Humanistic Practices

open access: yesJournal of Management Studies, EarlyView.
Abstract Repurposing management for the public good involves realizing alternative ideas to serve societal interests. Humanistic management is centred on such ideas as human dignity and well‐being. Realization refers to the generation and maintenance of social realities corresponding to these ideas.

Shaping the System Through Turbulence: Strategic Leadership and the Micro‐Foundations of Ecosystem Orchestration in Times of Disruption

open access: yesJournal of Management Studies, EarlyView.
Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...
