In Hollenbeck, a gang-dominated region of Los Angeles, gang activity has been monitored by the LAPD. One manner has been in the form of non-criminal stops. We propose a spectral clustering algorithm to predict gang affiliation from the information obtained from these stops. Despite the sparseness of data, the combination of geography and the record of individuals involved in a stop reveals the ...

Peter Hollenbeck is Professor and Associate Head of Biological Sciences at Purdue University. He did his PhD at the University of California-Berkeley with W. Zacheus Cande, followed by postdoctoral training with Dennis Bray at the MRC Cell Biophysics Unit in London. He then served on the Harvard Medical School faculty in the Department of Anatomy and Cell Biology, and later the Department of Ne...

We introduce a point process model for inter-gang violence driven by retaliation – a core feature of gang behavior – and multi-party inhibition. Here, a coupled system of statedependent jump stochastic differential equations is used to model the conditional intensities of the directed network of gang rivalries. The system admits an exact simulation strategy based upon Poisson thinning. The mode...

In this article we identify social communities among gang members in the Hollenbeck policing district in Los Angeles, based on sparse observations of a combination of social interactions and geographic locations of the individuals. This information, coming from LAPD Field Interview cards, is used to construct a similarity graph for the individuals. We use spectral clustering to identify cluster...

This document describes an Extensible Provisioning Protocol (EPP) mapping for the provisioning and management of Internet domain names stored in a shared central repository. Specified in XML, the mapping defines EPP command syntax and semantics as applied to domain names. This document obsoletes RFC 3731. Hollenbeck Standards Track [Page 1] RFC 4931 EPP Domain Name Mapping May 2007

This document describes an application layer client-server protocol for the provisioning and management of objects stored in a shared central repository. Specified in XML, the protocol defines generic object management operations and an extensible framework that maps protocol operations to objects. This document includes a protocol specification, an object mapping template, and an XML media typ...
