From a Civic‐Tech to a Problem‐Centered Approach to Open Government Data: Implementation of Environmental Justice Dashboards

open access: yesPublic Administration Review, Volume 86, Issue 1, Page 217-234, January/February 2026.
ABSTRACT This research investigates the configurations of openness and policy conditions influencing the implementation of environmental justice (EJ) open government data (OGD) dashboards across U.S. states. EJ dashboards represent a shift from a civic‐tech approach to OGD, which emphasizes the public release of vast amounts of data, to a problem ...

Bayesian population‐based assessment of ascertainment bias in flea‐borne typhus surveillance in California, 2011–2019

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 4, Page 765-775, December 2025.
Although flea‐borne typhus is historically associated with poorer living conditions, FBT surveillance reporting is associated with greater socioeconomic advantage at the population level. FBT surveillance may be biased towards socioeconomic advantage in its ascertainment of surveillance data.

Minimax Theory: A Summary [PDF]

open access: yes, 1982
We present here classical minimax inequalities as well as more recent ones, as the Ky Fan inequality and its variants, which play an important role not only in game theory, but in convex and non convex ...

On the deep‐water and shallow‐water limits of the intermediate long wave equation from a statistical viewpoint

open access: yesTransactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We study convergence problems for the intermediate long wave (ILW) equation, with the depth parameter δ>0$\delta > 0$, in the deep‐water limit (δ→∞$\delta \rightarrow \infty$) and the shallow‐water limit (δ→0$\delta \rightarrow 0$) from a statistical point of view.

The domination theorem for operator classes generated by Orlicz spaces

open access: yesMathematische Nachrichten, Volume 298, Issue 11, Page 3576-3598, November 2025.
Abstract We study lattice summing operators between Banach spaces focusing on two classes, ℓφ$\ell _\varphi$‐summing and strongly φ$\varphi$‐summing operators, which are generated by Orlicz sequence lattices ℓφ$\ell _\varphi$. For the class of strongly φ$\varphi$‐summing operators, we prove the domination theorem, which complements Pietsch's ...

Remarks on Nash equilibria for games with additively coupled payoffs (revision, previous title: An unusual Nash equilibrium result and its application to games with allocations in infinite dimensions) [PDF]

open access: yes, 1995
If the payoffs of a game are affine, then they are additively coupled. In this situation both the Weierstrass theorem and the Bauer maximum principle can be used to produce existence results for a Nash equilibrium, since each player is faced with an ...

Federated Learning With Differential Privacy Based on Summary Statistics

open access: yesEngineering Reports, Volume 7, Issue 10, October 2025.
As society progresses, the significance of data becomes increasingly prominent, and simultaneously, the privacy preserving of data is gaining more attention. We apply the Functional mechanism to federated learning and extend their method to (ϵ,δ)$$ \left(\epsilon, \delta \right) $$‐DP by adding Gaussian noise to the coefficient vector of polynomial ...

SOME MATRIX INEQUALITIES OF KY FAN TYPE

open access: yesTamkang Journal of Mathematics, 1995
Oneofthewell-knowngeneraliztionsoftheKantorovichinequalitywas given by Ky Fan who established his results for one positive definite matrix but for several vectors. Here we give corresponding results for several matrices and vectors. As well, a number of related inequalities are established.

On the inequalities of Ky Fan, Wang–Wang and Alzer

open access: yesJournal of Mathematical Analysis and Applications, 2002
Let \(A\), \(G\) and \(H\) (or \(A(a)\), \(G(a)\) and \(H(a)\)) be, respectively, the unweighted arithmetic, geometric and harmonic means of the real numbers \(a_1,\dots, a_n\) (\(a_i>0\), \(i= 1,\dots, n\)). Let \(1= (1,\dots, 1)\) and \(A^+= A(1+ a)\), \(G^+= G(1+a)\), \(H^+= H(1+ a)\), then \[ {1\over H^+}- {1\over H}\leq {1\over G^+}- {1\over G ...
