Youth curfew ordinances are a widely touted, yet little studied policy tool available to local police departments. This paper evaluates the effectiveness of curfew ordinances by comparing the arrest behavior of various age groups within a city before and after curfew enactment. The evidence suggests that curfews are effective at reducing both violent and property crimes committed by juveniles b...

Targeting sustainability in our industrial society requires integrating specific criteria the design process of products and processes. A paradigm shift is necessary economical, social political systems to ensure natural ecosystems preservation on planet while fulfilling needs. Various research methods have therefore emerged change way services are designed, developed, used discarded considerin...

My story begins on the third day of July in the year 1960. Early that morning, one could have seen Bill Wilson driving a heavily loaded, 18-wheel cattle truck as he began his ascent up the winding road that leads to the summit of the mountain. However, his destination was Summit Lake Flats (Fig. 1A), a broad stretch of tundra lying just below the peak but well above tree line at an elevation of...

Begins by creating a vision for dynamic performance measurement systems and goes on to describe the background to the work. Develops a model for integrated and dynamic performance measurement systems. Provides a critical review of existing frameworks, models and techniques against the model. Identifies that current knowledge and techniques are sufficiently mature to create dynamic performance m...

We develop a new method for analyzing the motion of the left ventricle (LV) of a heart from tagged MRI data. Our technique is based on the development of a new class of physics-based deformable models whose parameters are functions allowing the definition of new parameterized primitives and parameterized deformations. These parameter functions improve the accuracy of shape description through t...
