To mine or not to mine the deep seabed?: The relative influence of competing NGO views in defining “serious harm” to the marine environment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-24)Several studies have noted that the International Seabed Authority (ISA) scores low on public participation. However, none have studied the efforts of non-governmental organizations to exert influence on the ISA’s rulemaking processes. I examine how environmental NGOs and private mining contractors attempt to sway one narrow, but existential, part of the ISA’s draft exploitation regulations between ... -
Martingale Hardy Spaces and Some New Weighted Maximal Operators of Fejér Means of Walsh–Fourier Series
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-19)In this paper, we introduce some new weighted maximal operators of the Fejér means of the Walsh–Fourier series. We prove that for some “optimal” weights, these new operators indeed are bounded from the martingale Hardy space H<sub>p</sub>(G)to the Lebesgue space L<sub>p</sub>(G), for 0 < p < 1/2. Moreover, we also prove sharpness of this result. As a consequence, we obtain some new and well-known ... -
