July 5, 2023Public Health vs. Epidemiology
Epidemiology and public health are closely linked but serve distinct functions: epidemiology is the foundational science that studies the patterns, causes, and effects of disease in populations, while public health is the broader, applied field that translates that scientific evidence into community programs, policy, and prevention strategies. The CDC defines epidemiology as the study of the distribution and determinants of health-related states and events in specified populations, and the application of this study to the control of health problems, making it, at its core, the investigative science that identifies who is affected by disease, where, when, and why.

June 12, 2023The Wedding Cake Model of Criminal Justice
The wedding cake model of criminal justice is a theoretical framework developed by criminologist Samuel Walker that illustrates how the justice system treats criminal cases differently based on their perceived seriousness, not uniformly as formal law might suggest.
