Model fitting in Multiple Systems Analysis for the quantification of Modern Slavery: Classical and Bayesian approaches [PDF]

Journal of the Royal Statistical Society Series A: Statistics in Society, Volume 183, Issue 3, June 2020, Pages 691-736, 2019
Multiple systems estimation is a key approach for quantifying hidden populations such as the number of victims of modern slavery. The UK Government published an estimate of 10,000 to 13,000 victims, constructed by the present author, as part of the strategy leading to the Modern Slavery Act 2015.

Breakdown of Strong-Coupling Perturbation Theory in Doped Mott Insulators [PDF]

Phys. Rev. Lett. vol. 93, 267004 (2004), 2003
We show that doped Mott insulators, such as the copper-oxide superconductors, are asymptotically slaved in that the quasiparticle weight, $Z$, near half-filling depends critically on the existence of the high energy scale set by the upper Hubbard band. In particular, near half filling, the following dichotomy arises: $Z\ne 0$ when the high energy scale

Continuum Strong Coupling Expansion of Yang-Mills Theory: Quark Confinement and Infra-Red Slavery [PDF]

Nucl.Phys.B418:113-130,1994, 1993
We solve Schr\"odinger's equation for the ground-state of {\it four}-dimensional Yang-Mills theory as an expansion in inverse powers of the coupling. Expectation values computed with the leading order approximation are reduced to a calculation in {\it two}-dimensional Yang-Mills theory which is known to confine. Consequently the Wilson loop in the four-

On the Reliability of Multiple Systems Estimation for the Quantification of Modern Slavery [PDF]

Journal of the Royal Statistical Society: Series A (Statistics in Society), 1 - 37 (2022), 2021
The quantification of modern slavery has received increased attention recently as organizations have come together to produce global estimates, where multiple systems estimation (MSE) is often used to this end. Echoing a long-standing controversy, disagreements have re-surfaced regarding the underlying MSE assumptions, the robustness of MSE methodology,

CCC/Code 8.7: Applying AI in the Fight Against Modern Slavery [PDF]

arXiv, 2021
On any given day, tens of millions of people find themselves trapped in instances of modern slavery. The terms "human trafficking," "trafficking in persons," and "modern slavery" are sometimes used interchangeably to refer to both sex trafficking and forced labor.

The Coulomb gauge ghost Dyson-Schwinger equation [PDF]

Phys.Rev.D82:125010,2010, 2010
A numerical study of the ghost Dyson-Schwinger equation in Coulomb gauge is performed and solutions for the ghost propagator found. As input, lattice results for the spatial gluon propagator are used. It is shown that in order to solve completely, the equation must be supplemented by a nonperturbative boundary condition (the value of the inverse ghost ...

Narratives and Counternarratives on Data Sharing in Africa [PDF]

, 2021
As machine learning and data science applications grow ever more prevalent, there is an increased focus on data sharing and open data initiatives, particularly in the context of the African continent. Many argue that data sharing can support research and policy design to alleviate poverty, inequality, and derivative effects in Africa.

The ghost propagator in Coulomb gauge [PDF]

AIP Conf.Proc.1343:197-199,2011, 2010
We present results for a numerical study of the ghost propagator in Coulomb gauge whereby lattice results for the spatial gluon propagator are used as input to solving the ghost Dyson-Schwinger equation. We show that in order to solve completely, the ghost equation must be supplemented by a boundary condition (the value of the inverse ghost propagator ...

Multiple Systems Estimation for Sparse Capture Data: Inferential Challenges when there are Non-Overlapping Lists [PDF]

Journal of the American Statistical Association, 2020, 2019
Multiple systems estimation strategies have recently been applied to quantify hard-to-reach populations, particularly when estimating the number of victims of human trafficking and modern slavery. In such contexts, it is not uncommon to see sparse or even no overlap between some of the lists on which the estimates are based.

RaFoLa: A Rationale-Annotated Corpus for Detecting Indicators of Forced Labour [PDF]

arXiv, 2022
Forced labour is the most common type of modern slavery, and it is increasingly gaining the attention of the research and social community. Recent studies suggest that artificial intelligence (AI) holds immense potential for augmenting anti-slavery action.
