A comparative perspective on "The Life Sentence and Parole"

Especially given changes to LWOP sentencing in the United States now required by the Supreme Court's Eighth Amendment work in Graham and Miller, this new article appearing on SSRN provides interesting and important comparative insights on long prison terms.  The article by Diarmuid Griffin and Ian O'Donnell is titled "The Life Sentence and Parole," and here is the abstract:

Taking the life sentence as the new ‘ultimate penalty’ for many countries, this paper explores the factors associated with the release of life-sentence prisoners on parole. The Republic of Ireland is selected as a case study because it is in the unusual position of being influenced by European human rights norms as well as by the Anglo-American drive towards increased punitiveness.  As an apparent outlier to both the human rights and punitive approaches, or perhaps as a hybrid of sorts, the relative impact of the two models can be elucidated.  The article also provides an example of how small penal systems can be resistant to broader trends and the value of directing the criminological gaze upon countries where it seldom falls.
