Defining Canonical Momenta for Discretised SU(2) Gauge Fields
Get PDFIn this proceeding contribution we discuss how to define canonical momenta for SU(N) lattice
gauge theories in the Hamiltonian formalism in a basis where the gauge field operators are diagonal.
For an explicit discretisation of SU(2) we construct the momenta and check the violation of the
fundamental commutation relations
Simplicially driven simple contagion
Get PDFSingle contagion processes are known to display a continuous transition from an epidemic-free state to an
epidemic one, for contagion rates above a critical threshold. This transition can become discontinuous when two
simple contagion processes are coupled in a bidirectional symmetric way. However, in many cases, the coupling
is not symmetric and the nature of the processes can differ. For example, risky social behaviors—such as not
wearing masks or engaging in large gatherings—can affect the spread of a disease, and their adoption dynamics
via social reinforcement mechanisms are better described by complex contagion models rather than by simple
contagions, more appropriate for disease spreading. Here, we consider a simplicial contagion (describing the
adoption of a behavior) that unidirectionally drives a simple contagion (describing a disease propagation). We
show, both analytically and numerically, that, above a critical driving strength, such a driven simple contagion can
exhibit both discontinuous transitions and bistability, absent otherwise. Our results provide a route for a simple
contagion process to display the phenomenology of a higher-order contagion, through a driving mechanism that
may be hidden or unobservable in practical instances
Unforgotten Lives - Interactive Map and Unforgotten Lives: Clerkenwell walking app
No full textThese two web apps were designed for the Unforgotten Lives: Rediscovering Londoners of African, Caribbean, Asian and Indigenous Heritage 1560 – 1860 exhibition at the London Metropolitan Archives.
The Unforgotten Lives - Interactive Map, optimised for large screens, in the heart of the exhibition allows users to browse the dataset, focusing on individuals and locations. The Unforgotten Lives: Clerkenwell walking application, optimised for smartphone browsers, encourages visitors to interact with the indigenous heritage of London after leaving, extending the exhibit over the walls of the archives by directly exploring the city.

Measuring and controlling divisiveness in rank aggregation
Get PDFIn rank aggregation, members of a population rank issues to decide which are collectively preferred. Wefocus instead on identifying divisive issues that express disagreements among the preferences of individuals. We analyse the properties of our divisiveness measures and their relation to existing notions of polarisation. We also study their robustness under incomplete preferences and algorithms for control and manipulation of divisiveness. Our results advance our understanding of how to quantify disagreements in collective decision-making

Updating UK CSR legislation and potentials for voluntary application
No full textUK legislation is to follow the moral views of society, has begun to incorporate CSR into legislation, forcing companies to conform the voluntary inclusion of CSR into the business framework beyond the legislated minima. Although the incorporation of CSR is a relatively new concept, the relevant legislation does not address certain key points; this allows some companies to find loopholes within the law and perform actions that are damaging the environment, but are technically still within the constraints of the legislation. The absence of a structured assessment of legislations in the UK, against CSR guidelines has left legal escapes which some companies may exploit to avoid their social responsibility. To study the reality of this, thematic analysis was used to identify areas of CSR that are currently present within the UK legislation. Further, thematic analysis was also conducted on Carroll's sustainability pyramid to establish the main areas of CSR that are absent from the selected UK legislation. Accordingly, this study outlines a structured assessment of the current UK legislation in relation to CSR activities. Furthermore, we have provided a set of recommendations that can be espoused by the UK legislators
