The partnership approach to crime reduction and antisocial behavior is now well-established in the academic literature and the operational reality of many agencies. A more recent, and still developing aspect of such initiatives in the U.K., is the use of civil statutes alongside criminal law to tackle criminal and nuisance behavior. This paper features two case studies that describe the use of ...

Multi-tenancy is a relatively new software architecture principle in the realm of the Software as a Service (SaaS) business model. It allows to make full use of the economy of scale, as multiple customers –“tenants”– share the same application and database instance. All the while, the tenants enjoy a highly configurable application, making it appear that the application is deployed on a dedicat...

This paper proposes a special System Architecture for Multi-tenancy SaaS Service (SAMSS), which studies the performance security issues at the business logic layer and data processing layer respectively. The Kalman filtering Admission Control algorithm (KAC) and the Greedy Copy Management algorithm (GCM) are proposed. At the business logic layer, Kalman filtering admission control algorithm is ...

Cloud environments reduce data center operating costs through resource sharing and economies of scale. Infrastructure-as-a-Service is one example that leverages virtualization to share infrastructure resources. However, virtualization is often insufficient to provide Software-as-aService applications due to the need to replicate the operating system, middleware and application components for ea...

While most studies looking at the consequences of tenurial insecurity on land markets in developing countries focus on the effects of tenurial insecurity on the investment behavior of landowners, this paper studies the hitherto unexplored relationship between tenurial insecurity and contract choice in land tenancy. Based on a distinct feature of the interaction between formal law and customary ...

This paper presents Distributed Systems Foundation (DSF), a common platform for distributed systems research and development. It can run a distributed algorithm written in Java under multiple execution modes— simulation, massive multi-tenancy, and real deployment. DSF provides a set of novel features to facilitate testing and debugging, including chaotic timing test and time travel debugging wi...
