In the first instance, we suggest that qualitative interviews and focus groups with stakeholders at surgical trials departments will be important.
"We are confident that we would have proven his guilt beyond a reasonable doubt at a criminal trial," a department spokesman, Dean Boyd, said.
But as the second-degree murder case against the defendant, George Zimmerman, moves from the glare of a public spectacle to the grinding procedures of the court system and eventual trial, the department's performance, roundly criticized by Mr. Martin's family as bungling and biased, will be scrutinized once again, though in more meticulous detail.
The Los Angeles Police Department depicted during the trial — a department that employed a high-profile detective caught on tape saying the "N-word" word repeatedly and investigators and criminalists who bungled the handling of forensic evidence — has been transformed over the years into a far more diverse, more trusted force.
Fifteen departments from six construction companies participated in this cluster randomized controlled trial; 8 departments (n=171 workers) were randomized to an intervention group and 7 departments (n=122 workers) to a control group.
Below it are the Appeals Court and various trial court departments, including those of the superior courts (which conduct felony jury trials) and district courts.
In one of three steps to be trialled, the department will cut down on face-to-face referrals by getting its own staff to determine whether people are eligible for PIP using paper-only evidence.
In total, 924 participants enrolled in a 2-year cluster randomized controlled trial, with departments (n = 74) within companies (n = 6) as the unit of randomization.
However, the study's design – a controlled trial with departments allocated to conditions and two follow-up measurements - is as rigorous as possible in a practice-based study in (vocational) education.
In theory, a better design could be to run a cluster-randomized clinical trial, randomizing departments and clinics to program participation or not, but at the time when it was decided to run this study the SfW program was already established in many settings in Scandinavia.
