Characterizing the Temporal Regularities of Crime

There are a lot of studies that show that criminal activities exhibit certain temporal and spatial regularities. However, they often focus on either specific cities or types of crime and cannot clearly explain the patterns for the crime. What are the temporal patterns at the microlevel spatial scale? How general? Understanding the regularities of urban crime is important because it can help us improve the economy and safety of the cities and maintain harmony. This study analyzes the theft and burglary crime data from five cities in the United States. We successfully find the spatiotemporal patterns of two types of crime in different time series across cities.

Delineating Delhi: Spaces of the Neoliberal Urbanism in Tarun Tejpal’s The Story Of My Assassins

Recent Indo-Anglican literature has also seen a burgeoning of the genre of urban crime fictions set against the backdrop of India’s modernizing metropolises. While explorations of the contemporary Indian city mostly consists of non-fictional, journalistic writings, like Katherine Boo’s Pulitzer winning book Behind the Beautiful Forevers, William Dalrymple’s City of Djinns and Suketu Mehta’s Maximum City, the genre also includes fictions like Altaf Tyrewala’s critically acclaimed debut novel No God in Sight, Vikram Chandra’s bestseller Sacred Games, Tarun Tejpal’s The Story of My Assassins, Hrish Sawhney’s volume of short stories Delhi Noir, Atish Tasser’s The Templegoers and others, which deal with the dark underside of the cities. Significantly, as rapid urban growth deepens existing disparities, a distinct rhetoric conflating impoverishment and criminality emerges, further justifying the exclusion of certain sections from the vision of urbanism. This paper looks at the representation of Delhi in Tarun Tejpal’s novel The Story of My Assassins, as a dystopic space riddled with contradictions of.

On the global existence and qualitative behaviour of one-dimensional solutions to a model for urban crime

We consider the no-flux initial-boundary value problem for the cross-diffusive evolution system: \begin{eqnarray*} \left\{ \begin{array}{ll} u_t = u_{xx} - \chi \big(\frac{u}{v} \partial_x v \big)_x - uv +B_1(x,t), \qquad & x\in \Omega, \ t>0, \\[1mm] v_t = v_{xx} +uv - v + B_2(x,t), \qquad & x\in \Omega, \ t>0, \end{array} \right. \end{eqnarray*} which was introduced by Short et al. in [40] with $\chi=2$ to describe the dynamics of urban crime. In bounded intervals $\Omega\subset\mathbb{R}$ and with prescribed suitably regular non-negative functions $B_1$ and $B_2$ , we first prove the existence of global classical solutions for any choice of $\chi>0$ and all reasonably regular non-negative initial data. We next address the issue of determining the qualitative behaviour of solutions under appropriate assumptions on the asymptotic properties of $B_1$ and $B_2$ . Indeed, for arbitrary $\chi>0$ , we obtain boundedness of the solutions given strict positivity of the average of $B_2$ over the domain; moreover, it is seen that imposing a mild decay assumption on $B_1$ implies that u must decay to zero in the long-term limit. Our final result, valid for all $\chi\in\left(0,\frac{\sqrt{6\sqrt{3}+9}}{2}\right),$ which contains the relevant value $\chi=2$ , states that under the above decay assumption on $B_1$ , if furthermore $B_2$ appropriately stabilises to a non-trivial function $B_{2,\infty}$ , then (u,v) approaches the limit $(0,v_\infty)$ , where $v_\infty$ denotes the solution of \begin{eqnarray*} \left\{ \begin{array}{l} -\partial_{xx}v_\infty + v_\infty = B_{2,\infty}, \qquad x\in \Omega, \\[1mm] \partial_x v_{\infty}=0, \qquad x\in\partial\Omega. \end{array} \right. \end{eqnarray*} We conclude with some numerical simulations exploring possible effects that may arise when considering large values of $\chi$ not covered by our qualitative analysis. We observe that when $\chi$ increases, solutions may grow substantially on short time intervals, whereas only on large timescales diffusion will dominate and enforce equilibration.

Between containment and crackdown in Geylang, Singapore: Urban crime control as the statecrafting of migrant exclusion

Based on a case study conducted in Geylang, Singapore, this article explores the role of urban policing, surveillance and crime control as mechanisms of social ordering that contribute to the marginalisation of excluded groups, including low-income migrant workers and sex workers. Adopting a statecraft approach that emphasises the significance of ‘governing through crime’ for the upholding of urban political-economic projects, we examine the entanglement of political discourses and crime and social control practices as co-constructive of class- and race-based inequality in Singapore. Drawing from qualitative interviews with NGO workers and sex workers, augmented by extensive non-participant observations, we identify three processes through which state power is vectored in Geylang: the stigmatisation of the neighbourhood through association with marginalised groups, legitimising intense spatialised intervention; the enacting of performative zero-tolerance policing; and the containment and surveillance of illicit activities within the neighbourhood. Contributing to discussions that advance the statecraft approach to researching urban crime control, the article shows that seemingly contradictory practices of tolerance and intervention constitute strategies of governance. The article argues that spatially specific crime control practices in Geylang generated an exclusionary ‘spectacle’ which symbolically connects low-income migrant workers with deviance, in turn supporting citizenship exclusion, racialised marginality and a wider politics of capital accumulation resting on disempowered labour. As we argue, crime control policies are an important form of statecraft legitimising an urban political economy that is heavily reliant on low-cost labour provided by migrant workers.

Urban Crime Mapping: A Review

The imperfection of man is the banes of all criminal activities worldwide. More so, global urbanization and technological advancement seem to catalyze the frequency and complexity of criminal activities generally. Crime in its entire ramification is a critical issue that has gained significant attention in most countries of the world Nigeria inclusive. In view of the alarming rate of crime globally and the GIS utilities, this paper therefore carried out a review of the principles and theories of crime mapping, types of crime mapping and the nexus between poverty and urban crime. The paper further examined the relationship between urban design and spatial dimension of urban crime, and the implication for Urban and Regional Planning professional education as one of the key players in environmental management. It is therefore recommended that the teachings of Urban and Regional Planning in educational institutes should include the key theories within environmental criminology. While national and international conferences and workshops around urban and regional planning should presently revolve around settlement safety and urban governance.

A global analysis of the impact of COVID-19 stay-at-home restrictions on crime

The stay-at-home restrictions to control the spread of COVID-19 led to unparalleled sudden change in daily life, but it is unclear how they affected urban crime globally. We collected data on daily counts of crime in 27 cities across 23 countries in the Americas, Europe, the Middle East and Asia. We conducted interrupted time series analyses to assess the impact of stay-at-home restrictions on different types of crime in each city. Our findings show that the stay-at-home policies were associated with a considerable drop in urban crime, but with substantial variation across cities and types of crime. Meta-regression results showed that more stringent restrictions over movement in public space were predictive of larger declines in crime.
