An Informed and Systematic Method to Identify Variable Mid-L Dwarfs

The Astrophysical Journal
Most brown dwarfs show some level of photometric or spectral variability. However, finding the most variable dwarfs more suited for a thorough variability monitoring campaign remained a challenge until a few years ago with the design of spectral indices ...

L'envolée épistémique de la recherche comptable en économie financière : une étude historique sur la conception de l'utilité de la comptabilité* The Epistemic Rise of Accounting Research in Financial Economics: A Historical Study on the Conception of the Usefulness of Accounting

Contemporary Accounting Research, EarlyView.
RÉSUMÉ L'étude publiée par Ball et Brown en 1968 (ci‐après « BB68 ») est principalement reconnue pour son affirmation selon laquelle la comptabilité de l'époque était utile pour les investisseurs, s'inscrivant alors en contradiction avec la littérature comptable normative faisant office d'autorité. Or, une telle affirmation n'allait pas de soi.

Inspecting Cloudy Substellar Atmospheres with JWST MIRI Synthetic Magnitudes from Spitzer Mid-infrared Spectra

The Astrophysical Journal
We examine the positions of substellar objects in mid-infrared color–magnitude and color–color diagrams to distinguish between cloudy and cloud-free atmospheres.

Spectacle and Spy Stories: The 1954 Royal Commission on Espionage

Australian Journal of Politics &History, EarlyView.
ABSTRACT The Menzies government's 1954 royal commission, established to investigate Soviet espionage in Australia, is well known as the backdrop to the Labor Party split. It saw opposition leader H.V. Evatt's demise and ushered in an almost 20‐year period of Liberal Party governance.

The WIRC+Pol Brown Dwarf Survey: A J-band Polarimetric Survey of 22 Brown Dwarfs

The Astrophysical Journal
We present a near-infrared spectropolarimetric survey of brown dwarfs conducted with the WIRC+Pol instrument on the Palomar 200 inch Hale Telescope. The primary survey goal was to investigate the presence of polarization signatures arising from cloudy ...

Australian Royal Commissions Into Child Welfare, Abuse and Protection

Australian Journal of Politics &History, EarlyView.
ABSTRACT Both nationally and internationally, the Australian Royal Commission into Institutional Responses to Child Sexual Abuse (RCIRCSA) is widely viewed as a remarkably successful public inquiry. Unlike many other commissions, it was stable, attracted little controversy, was highly regarded, and led to extensive legal, regulatory and policy reform ...

Phosphine Depletion in Brown Dwarf Atmospheres Explained due to Metal Phosphide Formation

The Astrophysical Journal Letters
Phosphine (PH _3 ) is predicted to be the dominant phosphorus-bearing gas in cool substellar atmospheres, yet observations have revealed a puzzling pattern.

The Mutable Original: How Chinese Counterfeits Become Nigerian Originals in African Markets

American Anthropologist, EarlyView.
ABSTRACT Affordable Chinese copies of Western brands are ubiquitous in African markets. Despite democratizing consumer access, these goods appear to cement hegemonic value hierarchies that rank Chinese or local products as inferior to Western goods.

The Polar Vortex Hypothesis: Evolving, Spectrally Distinct Polar Regions Explain Short- and Long-term Light-curve Evolution and Color–Inclination Trends in Brown Dwarfs and Giant Exoplanets

The Astrophysical Journal Letters
Recent studies revealed viewing-angle-dependent color and spectral trends in brown dwarfs, as well as long-term photometric variability (∼100 hr). The origins of these trends are yet unexplained.
