Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This article examines the landmark decision in Commonwealth v. Mattis by the Massachusetts Supreme Judicial Court, which prohibits life without parole (LWOP) sentences for individuals aged 18 to 20, categorizing them as “emerging adults.” The ruling marks a significant shift in juvenile justice by extending constitutional protections against cruel and unusual punishment to young adults, based on contemporary neuroscience research indicating that brain development continues into the mid-twenties. The article discusses the implications of this decision for both the legal system and the approximately 200 individuals currently serving LWOP sentences in Massachusetts. By analyzing the majority and dissenting opinions, the article highlights the ongoing debate about the role of neuroscience in legal determinations and the potential for this decision to influence similar cases nationwide.
