An empirical examination of firearm users in Brasilia, DF
Economia Aplicada, 2009 This paper relates individuals' characteristics to the probability of possessing firearms: a) inside the home; b) outside the home; and c) inside and outside the home. Extending the literature on the demand for firearms whose focus is on the first trait,

Journal of Crime and Justice, 2021 Given notable recent spikes in gun purchases in the U.S., we revisit the ‘fear and loathing’ hypothesis of firearm demand by (1) establishing how crime/victimization fears are shaped by broader economic, cultural, and racial status anxieties (those ...

Advanced Functional Materials, EarlyView.Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

The segregated gun as an indicator of racism and representations in film
Humanities & Social Sciences Communications, 2020 Film emphasizes an ironic history of racism in gun control and ownership and a justification for seeking justice among the Black community, but film also perpetuates structural racism and bias, segregating Black from White, and failing to promote ...

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing
Advanced Materials, EarlyView.This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Advanced Materials, EarlyView.We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Dependence of the firearm-related homicide rate on gun availability: a mathematical analysis. [PDF]
PLoS ONE, 2013 In the USA, the relationship between the legal availability of guns and the firearm-related homicide rate has been debated. It has been argued that unrestricted gun availability promotes the occurrence of firearm-induced homicides.

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays
Advanced Materials, EarlyView.An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...
