Framing Modern Slavery: Do Stakeholders Talk Past Each Other?

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, EarlyView.
ABSTRACT Modern slavery literature has thus far mostly adopted a downstream perspective, in the sense that researchers investigated corporate actors' responses after the enactment of transparency legislation. The common finding is that corporate disclosure is poor and ineffective, contributing to a failure to eradicate modern slavery.

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick

The Astrophysical Journal Letters
The surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems.

Relativistic cross sections of tidal disruption events

EPJ Web of Conferences, 2012
In this contribution I introduce and discuss the so-called cross sections of tidal disruption and partial mass stripping of stars after a tidal encounter with a rotating supermassive black hole. The presented approach is fully relativistic.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Repeating Partial Tidal Encounters of Sun-like Stars Leading to Their Complete Disruption

The Astrophysical Journal
Stars grazing supermassive black holes on bound orbits may produce periodic flares over many passages, known as repeating partial tidal disruption events (TDEs).

Underluminous tidal disruption events

Monthly Notices of the Royal Astronomical Society
ABSTRACT We have evidence of X-ray flares in several galaxies consistent with a star being tidally disrupted by a supermassive black hole (MBH). If the star starts on a nearly parabolic orbit relative to the MBH, one can derive that the fallback rate follows a $t^{-5/3}$ decay.

Reviews of High‐Longevity Aqueous Zinc Metal Batteries Achieved by Programmable Interface Architectures

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review focuses on the mechanisms of Zn2+ electrodeposition and interfacial failure together with systematical artificial interphase layer design strategies from carbon materials, zincophilic alloys, to inorganic/organic compound layers, regulating ion flux and desolvation and providing guidance for programmable interface construction in aqueous ...

Repeated Partial Disruptions in a White Dwarf–Neutron Star or White Dwarf–Black Hole Merger Modulate the Prompt Emission of Long-duration Merger-type GRBs

The Astrophysical Journal Letters
The progenitors of gamma-ray bursts (GRBs) have long been an unresolved issue. GRB 230307A stands out as an exceptionally bright event, belonging to the long-duration GRBs but also exhibiting a late-emission component reminiscent of a kilonova.
