A Context-Aware Mobile-Based System for Crime Prevention and Emergencies

Crime is a global issue that arises as a consequence of social problems in society such as poverty and densely population due to urbanization. In large cities, governments have applied technology to support crime prevention. In this paper, a mobile-based system is proposed to increase knowledge and public awareness which may reduce the risk of crimes. A context-aware system, namely, geo-fence, is used to enable virtual fences around crime hotspots. Crime hotspots are determined using crime histories and crowd-sourced data provided by citizens. As citizens enter crime hotspots, they would be alerted and provided information. Meanwhile, if they find or experience crime, they are able to report and label the location of the crime

Conversational Sensing

Recent developments in sensing technologies, mobile devices and context-aware user interfaces have made it possible to represent information fusion and situational awareness as a conversational process among actors - human and machine agents - at or near the tactical edges of a network. Motivated by use cases in the domain of security, policing and emergency response, this paper presents an approach to information collection, fusion and sense-making based on the use of natural language (NL) and controlled natural language (CNL) to support richer forms of human-machine interaction. The approach uses a conversational protocol to facilitate a flow of collaborative messages from NL to CNL and back again in support of interactions such as: turning eyewitness reports from human observers into actionable information (from both trained and untrained sources); fusing information from humans and physical sensors (with associated quality metadata); and assisting human analysts to make the best use of available sensing assets in an area of interest (governed by management and security policies). CNL is used as a common formal knowledge representation for both machine and human agents to support reasoning, semantic information fusion and generation of rationale for inferences, in ways that remain transparent to human users. Examples are provided of various alternative styles for user feedback, including NL, CNL and graphical feedback. A pilot experiment with human subjects shows that a prototype conversational agent is able to gather usable CNL information from untrained human subjects

Safeguarding children and young people from sexual exploitation (consultation document)

An evaluation of the use of electronic monitoring as a condition of bail in Scotland

The aims of the evaluation were to assess the implementation of EM bail in replacing custodial remands, and to conduct a cost analysis of EM bail in contrast to those given custody. The study included the collection of qualitative and quantitative data, matched comparison data and cost analysis. Interviews were conducted with 10 Steering Group members and 45 professionals (comprising the police, social work, procurators fiscal, clerks of court, judges, sheriffs, defence agents, advocates, the electronic monitoring companies and victims' agencies). Interviews with 16 bailees and 15 household members were also undertaken. Quantitative data were collected from various sources, namely: court pro formas, Reliance/Serco databases, court files, social work files, police records, Scottish Criminal Record Office and data provided by the Scottish Executive Justice Statistics Branch, the Scottish Court Service and the Scottish Prison Service. Data from 3 comparison sheriff courts also provided a range of information on accused remanded in custody or bailed with or without conditions in areas outwith the pilot sites to ascertain whether EM bail is being used as a direct alternative to custodial remand and to explore differences in final sentences for the 2 groups

Pioneers in the Victorian provinces: veterinarians, public health and the urban animal economy

From the 1850s in Britain, concerns were growing about the role of animals in transmitting disease to man, whether through the food chain or through infection. While London is often seen as providing a model for public health reform, it was the great provincial cities that initiated veterinary involvement in public health in the closing years of the century. The emergence of this new strand of public health activity is the subject of this paper
