Objective: Law enforcement officers often encounter alcohol-intoxicated suspects, suggesting that many suspects are presented with the challenge of grasping the meaning and significance of their rights while intoxicated. Such comprehension is crucial, given that is intended to minimize the likelihood of coercive interrogations resulting in self-incrimination and protect suspects' constitutional rights. Yet, the effects of alcohol on individuals' ability to understand and appreciate their rights remain unknown-a gap that the present study sought to address.

Article Synopsis
  • The developing vertebrate eye cup consists of three main parts: the neural retina (NR), retinal pigmented epithelium (RPE), and ciliary margin (CM).
  • Single-cell analysis indicates that fibroblast growth factor (FGF) signaling is crucial for maintaining the stem cell-like properties of the CM, while Wnt signaling plays a pivotal role in differentiating the NR into CM or RPE based on FGF levels.
  • The research highlights that the relationship between FGF and Wnt signaling is essential for the transition from NR to CM during eye development, revealing a complex regulatory system that influences retinal formation.

Rationale: It is not uncommon for police to question alcohol-intoxicated witnesses and suspects; yet, the full extent to which intoxication impacts individuals' suggestibility in the investigative interviewing context remains unclear.

Objective: The present study sought to measure the effect of alcohol-intoxication on interviewee suggestibility by implementing a standardized suggestibility test with participants whose intoxication-state was the same at both encoding and recall.

Methods: We randomly assigned participants (N = 165) to an intoxicated (mean breath alcohol level [BrAC] at encoding = 0.

The Scale for the Assessment of Developmental Assets in the Neighborhood (SADAN) has shown acceptable psychometric properties for use in Spain and Chile. However, the original factor structure of five correlated factors and a second-order factor is not yet entirely clear. This study aimed to evaluate the scale's psychometric properties of reliability and validity in a sample of Chilean adolescents.
