Black and Hispanic Men Perceived to Be Large Are at Increased Risk for Police Frisk,Search, and Force

Social justice issues remain some of the most pressing problems in the United States. One aspect of social justice involves the differential treatment of demographic groups in the criminal justice system. While data consistently show that Blacks and Hispanics are often treated differently than Whites, one understudied aspect of these disparities is how police officers'' assessments of suspects'' size affects their decisions. Using over 3 million cases from the New York Police Department (NYPD) Stop, Question, and Frisk (SQF) Database, 2006–2013, this study is the first to explore suspects'' race, perceived size, and police treatment. Results indicate that tall and heavy black and Hispanic men are at the greatest risk for frisk or search. Tall and heavy suspects are at increased risk for experiencing police force, with black and Hispanic men being more likely to experience force than white men across size categories.     

Binding of the hydrophilic beta-adrenergic antagonist [3H]CGP-12177 to cardiac tissue slices: characterization and ontogenetic studies in dogs

A new technique was developed to characterize the binding of a hydrophilic beta-adrenergic antagonist, [3H]CGP-12177, to 1-mm thick slices of canine cardiac tissue. This technique was used to quantify the density (Bmax) and the affinity (Kd) of these receptors in the right ventricular conus (RVC) and the left ventricle (LV) at day 1 to 6 weeks of age, and in the adult. Binding was found to be reversible, saturable, stereospecific, of high affinity, and thermolabile. There was an increase in the density of beta-adrenergic receptors between day 1 (Bmax = 2.2 +/- 0.3 fmol/mg tissue in RVC and 2.9 +/- 0.8 fmol/mg tissue in the LV) and 2 weeks of age postnatally, after which it remained constant until 6 weeks of age (Bmax = 7.5 +/- 0.4 and 6.8 +/- 0.9 fmol/mg tissue in RVC and LV, respectively); however, by 6 weeks of age it had not reached adult levels (10.3 +/- 1.0 fmol/mg tissue). The affinity of these receptors did not change between early neonatal life (Kd = 1.3 +/- 0.4 nM) and adulthood (Kd = 1.4 +/- 0.2 nM). The density of beta-adrenergic receptors in the RVC was similar to that in the LV. This new method of quantifying beta-adrenergic receptors in cardiac tissue is simple and fast, and requires minimal tissue handling. It proved to be useful in studying the development of cardiac beta-adrenergic receptors with age.
