White dwarf variability

There are a few different mechanisms that can cause white dwarf stars to vary in brightness, providing opportunities to probe the physics, structures, and formation of these compact stellar remnants. The observational characteristics of the three most common types of white dwarf variability are summarized: stellar pulsations, rotation, and ellipsoidal ...

“Train and Hope”: The Role of Restorative Justice Coordinators in Sustaining a Culture of Care in Schools

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article examines the role of restorative justice coordinators in supporting teachers and schools in adopting a whole‐school approach to restorative justice in education. Coordinators are often tasked with implementing a train‐and‐hope model, in which they receive initial training in restorative justice but are largely left unsupported ...

Asteroseismology of the ZZ Ceti and DAZ GD133

EPJ Web of Conferences, 2017
GD 133 is a DAZ white dwarf with an atmosphere polluted by heavy elements accreted from a debris disk, which is formed by the disruption of rocky planetesimals with orbits bringing them at the white dwarf tidal radius.

Social Media Green Marketing: How Self‐Monitoring Shapes Consumer Engagement and Eco‐Purchase Intentions

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Marketing scholars and practitioners are paying increasing attention to social media as a crucial tool for communicating firms' sustainable activities to consumers. This study examines how consumers perceive and engage with social media green marketing, and how their engagement influences their intentions to purchase green products and brands,

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

KIC 4552982: outbursts and pulsations in the longest-ever pseudo-continuous light curve of a ZZ Ceti

EPJ Web of Conferences, 2015
KIC 4552982 was the first ZZ Ceti (hydrogen-atmosphere pulsating white dwarf) identified to lie in the Kepler field, resulting in the longest pseudo-continuous light curve ever obtained for this type of variable star.
