Geography of race and income shape spatial data gaps in two national participatory science projects

People and Nature, EarlyView.
Abstract Context and Need: Participatory projects where people contribute geo‐referenced biodiversity data, like eBird and iNaturalist, are commonly used tools to enhance the data collection capacity for research, management, and environmental learning. Despite their utility, demographic disparities in participation, demographic patterns of residential

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

Pest Management Science, EarlyView.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Condensation and Evaporation of Mutually Repelling Particles :Steady states and limit cycles

, 2003
We study condensation and evaporation of particles which repel each other, using a simple set of rules on a square lattice. Different results are obtained for a mobile and an immobile surface layer.A two point limit cycle is observed for high temperature

UAVs unveil the role of small scale vegetation structure on wader nest survival

Remote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Task co‐use and product improvement: An organization design perspective

Strategic Management Journal, EarlyView.
Abstract Research Summary Co‐using tasks—using the same task to produce more than one product—promises economies of scope. However, task co‐use also ties products together, changing a firm's task network by introducing cross‐product interdependencies. In light of these interdependencies, we identify an unrecognized downside of task co‐use for product ...

Hiring at the tip of the funnel: Externalizing the work of integrating and coordinating diverse human capital

Strategic Management Journal, EarlyView.
Abstract Research Summary We adopt a network‐based perspective to examine the effects of hiring strategies in terms of the diversity of hiring sources. Considering the transferability of general and firm‐specific skills, we propose that firms can reduce integration costs while gaining diversity benefits when they hire from a focused set of firms that ...

A Bird's Eye View of English Grammar: Connecting the Dots in Two Dimensions

TESOL Quarterly, EarlyView.
Abstract Over the past few decades, discussions on grammar instruction have primarily focused on teaching methodologies, such as whether grammar should be taught explicitly or implicitly, and whether the focus should be on form or forms. This paper, however, shifts the focus to grammar itself, aiming to provide a “shape” for pedagogical grammar.
