Financially Coerced ‘Self‐Produced’ Child Sexual Exploitation Material: Narratives of Accountability

Child &Family Social Work, EarlyView.
ABSTRACT Perpetrators financially coerce children to ‘self‐produce’ child sexual exploitation material (CSEM). A harmful dominant narrative has historically blamed victims by framing this form of child sexual exploitation as ‘children engaging in sex work’ obfuscating the tactics of perpetrators.

Pursuit—Evasion games on graphs

Journal of Graph Theory, 1988
AbstractTwo players, Red and Blue, each independently choose a vertex of a connected graph G. Red must then pay Blue an amount equal to the distance between the vertices chosen. In this note, we investigate the value ν(G)of this pursuit‐evasion game for various classes of graphs G, as well as those optimal mixed strategies for achieving ν(G).

A Note on Generalized Pursuit-Evasion Games

SIAM Journal on Control, 1975
Two player zero sum differential games are an extension of optimal control problems. When the cost or payoff is the integral of some function h up to the first time the trajectory enters a “terminal set” the differential game is one of survival. If $h \equiv 1$, the payoff is just the time elapsed up to the “capture time” and the game is one of pursuit

Harbor attack: A pursuit-evasion game

2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011
This paper studies a concrete pursuit-evasion game in which the evader, a.k.a. the intruder, tries to reach a harbor via a rectangular channel, while the pursuer, a.k.a. the defender, tries to stop him. Our goal is to develop insight into the nature of this game, the impact of the quality of information, and the potential evasion and defense numerical ...

Dominance in pursuit-evasion games with uncertainty

2015 54th IEEE Conference on Decision and Control (CDC), 2015
This paper studies planar pursuit-evasion games that feature a group of players moving in an environment that may contain obstacles, where some players are pursuers and others are evaders. The goal of the pursuers is to capture the evaders, which requires the distance between one of the pursuers and one of the evaders to become zero.

A Pursuit-Evasion Game with Incomplete Information

2019 27th Mediterranean Conference on Control and Automation (MED), 2019
A pursuit-evasion game with partial information is studied. The evader observes the initial conditions only. The pursuer observes both the initial conditions and the relative evader-pursuer position in additive noise. The paper shows that the optimal strategies of a partial information game may differ qualitatively from its full information counterpart.

Visibility Induction for Discretized Pursuit-Evasion Games

Proceedings of the AAAI Conference on Artificial Intelligence, 2021
We study a two-player pursuit-evasion game, in which an agent moving amongst obstacles is to be maintained within ``sight" of a pursuing robot. Using a discretization of the environment, our main contribution is to design an efficient algorithm that decides, given initial positions of both pursuer and evader, if the evader can take any ...

A pursuit-evasion game with hybrid pursuer dynamics

2007 European Control Conference (ECC), 2007
In this paper the authors study the pursuit-evasion game with hybrid dynamics of the pursuer and give a new approach to the solution of this game. The approach takes into account the ZEM (Zero-Effort Miss) discontinuity, yielding a new auxiliary game with impulsive dynamics.
