A handful of highly publicized sexual assault cases served as the impetus for the passage of sex offender legislation, culminating in the Adam Walsh Child Protection and Safety Act (2006), which called for the registration of convicted sex offenders in all 50 states and the District of Columbia. The publicly accessible online registries have been the center of sex offender controversy in recent years, yet few researchers have analyzed the content of the registries. This study examined the content of the registries after the deadline for implementation of the Adam Walsh Act (AWA). An analysis of the 51 online registries was conducted to identify prevalent characteristics, search features, listing profile details, and rates of sex offenders. The most common search features included searching by name, zip code, city or town, county, and address. Nearly all registries also provide disclaimers (98%) and warnings (92%). Thirty registries (58.8%) allowed users to plot an offender’s address through a mapping option. Most sites also provided numerous case-specific characteristics including various personal details about sex offenders such as appearance, specific offense information, victim information, and place of employment. Overall, the sites varied greatly from state to state and many offered additional features not required by the AWA. However, as of December 2011 only 15 states had substantially complied with AWA mandates (National Conference of State Legislatures).
Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent of location. In reality, the success of hydrogen projects will be intimately linked to the availability of local energy resources, access to key infrastructure and water supplies, and the distance to export ports and energy markets. In this paper, we present an economic model that incorporates assessments of these regional factors to identify areas of high economic potential for hydrogen production -the so-called "Economic Fairways" for such projects. In doing so, the model provides a tool that can be used to inform investors and policy makers on the available opportunities for hydrogen development and their infrastructure requirements. The model includes analysis of the regional economic potential for both blue and green hydrogen projects. It accounts for hydrogen production from renewable (wind and solar) sources, as well as non-renewable sources (steam-methane reformation and coal gasification) combined with carbon capture and storage. Results from case studies conducted with the tool are presented, illustrating the potential for hydrogen production across Australia.
Repeat victimization can be understood as repeat targets; those targets can be persons (e.g. a victim of domestic violence), objects (e.g. motor vehicle), or property (e.g. a precise address, a business chain with several locations). According to a typology of repeat victimization, victims can be classified into four types, namely true repeat victims, near victims, virtual repeats, and chronic victims.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
