Dark Sides of Digital Asset Consumption and Consumer Well‐Being: Impact of Psychological Ownership

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT This research contributes to the literature on consumer digital asset consumption by developing a novel model that examines the effects of psychological ownership on two dark‐side consumption behaviors: digital hoarding and digital piracy. It further examines how these behaviors influence consumer psychological outcomes, specifically, anxiety ...

Brown dwarfs as Galactic chronometers [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
AbstractBrown dwarfs are natural clocks, cooling and dimming over time due to insufficient core fusion. They are also numerous and present in nearly all Galactic environments, making them potentially useful chronometers for a variety of Galactic studies.

The Versatility of Diazirines: Properties, Synthetic and Modern Applications

open access: yesChemistry – A European Journal, EarlyView.
Diazirines are 3‐membered heterocycles containing two nitrogen atoms connected by a double bond. They possess a multi‐faceted reactivity that holds great potential for organic synthesis. This review discusses their properties, modes of activation, and their many modern uses, underlining their underappreciated versatility: as carbene precursors, but ...

Where lies the peak of the brown dwarf binary separation distribution ?

open access: yes, 2008
Searches for companions of brown dwarfs by direct imaging probe mainly orbital separations > 3-10 AU. On the other hand, previous radial velocity surveys of brown dwarfs are mainly sensitive to separations smaller than 0.6 AU.

The Dynamics of ESG Peer Pressure and Corporate Resilience: Examining Through Firm‐Perceived EPU and Governance Efficiency Perspectives

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores how environmental, social, and governance (ESG) performance‐based peer pressure influences corporate resilience, with a focus on the moderating effects of firm‐perceived economic policy uncertainty (FEPU) and governance efficiency (GE).

Shaping the Brown Dwarf Desert: Predicting the Primordial Brown Dwarf Binary Distributions from Turbulent Fragmentation

open access: yes, 2013
The formation of brown dwarfs (BDs) poses a key challenge to star formation theory. The observed dearth of nearby ($\leq 5$ AU) brown dwarf companions to solar-mass stars, known as the brown dwarf desert, as well as the tendency for low-mass binary ...

Cloud Atlas: Discovery of Rotational Spectral Modulations in a Low-mass, L-type Brown Dwarf Companion to a Star [PDF]

open access: yes, 2017
Observations of rotational modulations of brown dwarfs and giant exoplanets allow the characterization of condensate cloud properties. As of now, rotational spectral modulations have only been seen in three L-type brown dwarfs.
