The Stanford Prison Experiment03:20

The Stanford Prison Experiment

23.7K
The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Actuarial Approach01:20

Actuarial Approach

135
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Applications of Life Tables01:22

Applications of Life Tables

124
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Regression Toward the Mean01:52

Regression Toward the Mean

6.5K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Assumptions of Survival Analysis01:15

Assumptions of Survival Analysis

197
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Kaplan-Meier Approach01:24

Kaplan-Meier Approach

264
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Summary
This summary is machine-generated.

Incarceration significantly lowers mortality risk, especially from murder and overdose, leading to increased longevity for incarcerated individuals. This highlights the dangerous environment outside of prison and suggests policy changes.

Area of Science:

  • Criminology
  • Public Health
  • Sociology

Background:

  • Incarceration's impact on mortality is a critical public health and sociological concern.
  • Previous research has not fully elucidated the mortality risks associated with incarceration and release.

Purpose of the Study:

  • To analyze the effect of incarceration on mortality using administrative data.
  • To investigate the differential mortality risks between incarcerated and non-incarcerated individuals.
  • To examine the impact of release from incarceration on mortality risk.

Main Methods:

  • Analysis of administrative data from Ohio (1992-2017).
  • Event study designs centered around the time of release from incarceration.
  • Comparison of survival rates between incarcerated and similar non-incarcerated defendants.

Main Results:

  • Long-run survival is higher among incarcerated individuals compared to similar non-incarcerated defendants.
  • Mortality risk is halved during incarceration, with significant reductions in deaths from murder, overdose, and natural causes.
  • Incarceration does not increase post-release mortality, resulting in overall increased longevity.

Conclusions:

  • The findings suggest that the period of incarceration offers protective effects against high-risk behaviors and environments.
  • The study underscores the elevated mortality risks faced by defendants in non-incarcerated settings.
  • Results imply that non-carceral policies aimed at reducing risks in the community could mitigate mortality disparities.
