Abstract Social mixing patterns are crucial in driving transmission of infectious diseases and informing public health interventions to contain their spread. Age-specific social is often inferred from surveys self-recorded contacts which by design have a very limited number participants. In addition, such rare, so evaluated considering only one study. Here we report detailed population contact for United Kingdom based self-reported data over 36,000 volunteers that participated the massive...
Abstract Background Isolation of symptomatic cases and tracing contacts has been used as an early COVID-19 containment measure in many countries, with additional physical distancing measures also introduced outbreaks have grown. To maintain control infection while reducing disruption to populations, there is a need understand what combination – including novel digital approaches less intensive may be required reduce transmission. Methods Using model individual-level transmission stratified...
In August 2011, several areas of London experienced episodes large-scale disorder, comprising looting, rioting and violence. Much subsequent discourse has questioned the adequacy police response, in terms resources available strategies used. this article, we present a mathematical model spatial development which can be used to examine effect varying policing arrangements. The is capable simulating general emergent patterns events focusses on three fundamental aspects: apparently-contagious...
Explaining why crime is spatially concentrated has been a central theme of much criminological research. Although various theories focus on neighborhood social processes, environmental criminology asserts that the physical environment plays role by shaping people's activity patterns and opportunities for crime. Here, we test theoretical expectations regarding road network in spatial distribution and, contrast to prior research, disentangle how it might influence offender awareness criminal...
In this paper, a unique dataset of improvised explosive device attacks during “The Troubles” in Northern Ireland (NI) is analysed via Hawkes process model. It found that past dependent model good fit to yielding key insights about the nature terrorism NI. We also present novel approach quantitatively investigate some sociological theory surrounding Provisional Irish Republican Army which challenges previously held assumptions concerning changes seen organisation. Finally, we extend our use...
We present a spatial interaction entropy maximizing and structural dynamics model of settlements from the Middle Bronze Age (MBA) Iron Ages (IA) in Khabur Triangle (KT) region within Syria.The addresses factors that make locations attractive for trade settlement, affecting settlement growth change.We explore why some sites become relatively major settlements, while others diminish periods discussed.We assess how political geographic constraints affect regional transformations, also...
An outbreak of isoniazid-resistant tuberculosis first identified in London has now been ongoing for 20 years, making it the largest drug-resistant documented to date worldwide. We culture-confirmed cases with indistinguishable molecular strain types and extracted demographic, clinical, microbiological social risk factor data from surveillance systems. summarised changes over time used kernel-density estimation k-function analysis assess geographic clustering. From 1995 2014, 508 were...
In an era of budget constraints for healthcare services, strategies provision services that improve quality whilst saving costs are highly valued. A proposed means to achieve this is consolidation into fewer specialist centres, but may lead reduced spatial accessibility. We describe a methodology which includes implementing combinatorial optimisation algorithm derive combinations optimise accessibility in the context service rationalisation, and demonstrate its use through exemplar...
In both historical and modern conflicts, space plays a critical role in how interactions occur over time. Despite its importance, the spatial distribution of adversaries has often been neglected mathematical models conflict. this paper, we propose an entropy-maximising interaction method for disaggregating impact space, employing general notion ‘threat’ between two adversaries. This approach addresses number limitations that are associated with partial differential equation approaches to...

Abstract We present human mobility data for the United Kingdom collected from “BBC Pandemic”, a public science project linked to BBC Four television documentary of same name. Mobile phone GPS trajectories submitted by users and over 24 hour period were aggregated construct anonymised origin-destination flux matrices at local administrative district (LAD). use these explore how patterns change with age employment status - unique stratifications that are not available other publicly privately...
Geographic profiling, a mathematical model originally developed in criminology, is increasingly being used ecology and epidemiology. profiling boasts wide range of applications, such as finding source populations invasive species or breeding sites vectors infectious disease. The provides cost-effective approach for prioritizing search strategies locations does so via simple data the form positions each observation, individual sightings cases In doing so, however, classic geographic...
Entropy maximising spatial interaction models have been widely exploited in a range of disciplines and applications: from trade migration flows to the spread riots understanding patterns archaeological sites interest. When embedded into dynamic system framed context retail model, dynamics centre growth poses an interesting mathematical problem, with bifurcations phase changes, which may be addressed analytically. In this paper, we present some analysis continuous model corresponding discrete...
