Political Responsibility for Climate Change

Global structural injustices are harms caused by structural processes, involving multiple individuals, acting across more than one state. Young (2011) developed the concept of ‘political responsibility,’ to allocate responsibility for structural injustice. In this paper, I am going to argue that when considering the climate crisis Young’s model needs to be adapted— to have agency as a basis for allocating political responsibility instead of contribution. This is a more intuitive way to allocate responsibility for the climate crisis given its nature as a threshold problem, and the subtle structural positions occupied by the individuals involved

Automatic Zig-Zag sampling in practice

Novel Monte Carlo methods to generate samples from a target distribution, such as a posterior from a Bayesian analysis, have rapidly expanded in the past decade. Algorithms based on Piecewise Deterministic Markov Processes (PDMPs), non-reversible continuous-time processes, are developing into their own research branch, thanks their important properties (e.g., correct invariant distribution, ergodicity, and super-efficiency). Nevertheless, practice has not caught up with the theory in this field, and the use of PDMPs to solve applied problems is not widespread. This might be due, firstly, to several implementational challenges that PDMP-based samplers present with and, secondly, to the lack of papers that showcase the methods and implementations in applied settings. Here, we address both these issues using one of the most promising PDMPs, the Zig-Zag sampler, as an archetypal example. After an explanation of the key elements of the Zig-Zag sampler, its implementation challenges are exposed and addressed. Specifically, the formulation of an algorithm that draws samples from a target distribution of interest is provided. Notably, the only requirement of the algorithm is a closed-form function to evaluate the target density of interest, and, unlike previous implementations, no further information on the target is needed. The performance of the algorithm is evaluated against another gradient-based sampler, and it is proven to be competitive, in simulation and real-data settings. Lastly, we demonstrate that the super-efficiency property, i.e. the ability to draw one independent sample at a lesser cost than evaluating the likelihood of all the data, can be obtained in practice.Comment: Small edits from previous version following some minor revisions requeste

An Evaluation of the NHS England Youth Forum

More than five decades ago the Platt Report (Ministry of Health, 1959) recommended that hospitalised children needed to be treated differently to adults. It took until the 1980s for evidence to emerge that healthcare staff were beginning to implement Platt’s recommendations; Davies (2010) attributes this long awaited change of approach to a new generation of practitioners and a renewed focus from the Government that acknowledged the distinct needs of children and young people. In the early 1990s James and Prout (1990) produced work to suggest that children should not be viewed as passive recipients of care but should be recognised as having their own voice, referred to as the “emergence of children’s voice” (Hallett and Prout, 2003: 1)Peer reviewedFinal Published versio
