The choice argument for proportional representation

American Journal of Political Science, EarlyView.
Abstract What electoral system should a democracy choose? I argue for proportional representation (PR). My main empirical premise is Duverger's law: Under PR there are more viable candidates in district‐level elections than there are under single‐member plurality (SMP) systems.

Strategic litigation as a challenge for deliberative democracy

American Journal of Political Science, EarlyView.
Abstract Strategic litigation is a growing public concern, but remains understudied in democratic theory. In strategic litigation, collectives go to court with a political agenda that goes beyond their specific case. How should we assess the legitimacy of strategic litigation? Building on Lafont's model of deliberative democracy and Klein's distinction

Traffic adversarial example attack and defense method based on explainable artificial intelligence

Tongxin xuebao
An adversarial example attack method based on XAI was proposed for AI-based NIDS. By identifying critical perturbation features with XAI and applying targeted perturbations while preserving traffic functionality, malicious traffic was gradually altered ...

Family‐Led Decision‐Making Meetings as an Alternative to Initial Child Protection Conferences: Findings From a Realist Evaluation of the Safeguarding Family Group Conferencing Pilot in England

Child &Family Social Work, EarlyView.
ABSTRACT Safeguarding Family Group Conferencing (FGC) is a family‐led decision‐making process offered to some families in England as an alternative to an Initial Child Protection Conference when Children's Services have safeguarding concerns. A realist evaluation was conducted within three local authorities piloting this approach to build understanding

Between Care and Control: Age Assessments and the Regulation of Unaccompanied and Asylum‐Seeking Children

Child &Family Social Work, EarlyView.
ABSTRACT This article offers a critical conceptual review of age assessments in England and examines their implications for unaccompanied asylum‐seeking children (UASC). Drawing on Foucault's theories of biopower and governmentality, age assessments are conceptualied as technologies of control that set the parameters for who is deemed ‘deserving’ of ...
