"The goal of the present project is to provide governments and related organizations with a methodology to increase insight into the determinants of actual and perceived security, and into which interventions are effective for increasing security. The deliverables of this project represent practical and ready-to-use tools, which can be employed by policy makers and other end-users, to formulate policy regarding security. This project is a re-submittal of a proposal for PASR in 2006. In this project we will develop 1) a conceptual model of actual and perceived security and their determinants, 2) a methodology to collect, quantify, organize, analyse and interpret security-related data, 3) a data warehouse to store and extract for analysis data amassed using the methodology, and 4) carry out a validation study to test the model, methodology and data warehouse. We will test if it is possible to answer relevant security-related questions from the field using the methodology. The project deliverables can be used by end-users to assess security at the international, national and local levels and to draw conclusions regarding such issues as: What are the levels of actual and perceived security in specific locations?, Which interventions work where?, and Which interventions should be implemented in which locations?"
