Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Ocular safety of 222‐nm far‐ultraviolet‐c full‐room germicidal irradiation: A 36‐month clinical observation

open access: yesPhotochemistry and Photobiology, EarlyView.
A 36‐month observational study evaluated the ocular safety of 222‐nm UV‐C irradiation in physicians exposed in an ophthalmic room. No acute or chronic ocular damage was detected, and key ocular parameters remained unchanged. The findings support the safe use of 222‐nm UV‐C for disinfection, aligning with safety threshold guidelines. Abstract The ocular

Inherent constraints on imagistic imagination

open access: yesPhilosophy and Phenomenological Research, EarlyView.
Abstract A common and influential view sees imagistic imagining as an inherently free and unbounded type of thought that can nevertheless be subjected to epistemic constraints in individual instances. On this view, epistemic constraints can be imposed on imagistic imaginings to varying degrees, or not at all. The application of such constraints is said

Measuring and Harmonising Coverage, Generosity and History of Work‐Injury Policies Globally

open access: yesSocial Policy &Administration, EarlyView.
ABSTRACT I present new measures of generosity, coverage and institutional characteristics of work‐injury policy across 189 countries in the Global Work‐Injury Policy Dataset (GWIP) version 2.0. To date, major research efforts produced detailed social policy data for the rich Western countries, and more recently countries of Eastern, Central and Central‐
