Research by Professor John Clarke found that public service users and providers view services as distinct from market-based transactions, prioritizing personal relationships over choice. Users seek skilled, trustworthy staff and reliable assistance during critical life events.
Contrary to police reports, which attribute rising crime rates to increased surveillance and policing efforts, research shows a significant decrease in violent crime episodes in the US and a 36% fall in British violent crime since 1995. Hospital emergency data support these findings, revealing a decline in non-self-inflicted injuries.
Researchers at NIST are working on 'intelligent' building systems that provide real-time data to firefighters and police, enhancing their response to emergencies. These systems will send information such as floor plans and sensor data directly to dispatchers, enabling more accurate assessments and mitigation of emergencies.
Researchers found that a friendly-but-firm police presence, combined with preventing known troublemakers from travelling, led to an almost incident-free tournament. The study's 'low profile' tactics are credited with fostering peace among fans and reducing hooliganism.
False confessions are a significant issue in law enforcement, with various factors contributing to their occurrence. Research suggests that mandatory videotaping of police interviews and interrogations could help reduce these cases by providing an objective record of the proceedings.
A review published in Psychological Science in the Public Interest suggests that videotaping interrogations can curb false confessions. The authors propose that all interviews and interrogations should be recorded in their entirety to accurately assess confessions.
A recent study found that African-American and Latino youth are more likely to perceive the criminal justice system as unjust, with perceptions increasing as integration levels increase. However, schools with higher proportions of white students show a decrease in perceptions of injustice.
NIST's special test arena is used to train bomb and drug sniffing dogs as well as robotic rescue systems. The arenas provide a challenging environment for dogs to find hidden explosives or narcotics, while robotics experts observe police techniques.
A computer simulation study found that police officers can eliminate racial bias when trained using the program. After extensive exposure, officers became more accurate in their decisions to fire at suspects of either race due to improved weapon detection. The findings have implications for eliminating racial biases and training police...

Researchers at UH Cullen College of Engineering are developing advanced features for
Researchers at Ohio State University conducted experiments showing that white Americans are more likely to misidentify tools as guns when shown a picture of an African American before seeing the tool or gun. In contrast, they were less likely to make this mistake when shown a picture of a white person. The study suggests that unconscio...
A study by Professor Simon Holdaway found that chief officers and black police association Chairs have different ideas on 'institutional racism', with a focus on personal experiences of racism. Most minority ethnic officers agree their constabulary is institutionally racist, but the causes and effects differ between groups.

The lab also will modify a database for parole supervision, allowing corrections officers to track violations more effectively and encourage compliance.
Alcohol abuse contributes to major causes of death among college-age persons. Raising the drinking age has saved 16,500 lives in traffic crashes since 1975. Comprehensive community interventions involving public officials, private citizens, and student participation can further reduce alcohol-related problems.
A University of North Carolina study found that most NC police officers think the state law restricting tobacco sales to adults only should be changed due to its ineffectiveness in preventing youth access. Only a small percentage of officers try to enforce the law, citing barriers such as lack of manpower and poorly written legislation.
