    In 2013, the Vera Institute of Justice launched the Unlocking Potential: Pathways from Prison to Postsecondary Education Project (Pathways), a five-year multi-state demonstration project aiming to increase educational attainment and employment opportunities for incarcerated and formerly incarcerated individuals by supporting an expansion of educational opportunities in prison. Corrections departments in the states of New Jersey, Michigan, and North Carolina were selected to participate in the initiative. Each college-in-prison program—although executed differently and offering varying programs of study—possessed one common theme: to equip incarcerated persons with the tools necessary to end the cycle of incarceration through high-quality postsecondary education. This paper examines approaches to student recruitment the Michigan site took during its implementation phase and suggests potential outcomes for college-in-prison programs to consider when using the “return communities” approach

    KOI-142, the King of Transit Variations, is a Pair of Planets near the 2:1 Resonance

    The Transit Timing Variations (TTVs) can be used as a diagnostic of gravitational interactions between planets in a multi-planet system. Many Kepler Objects of Interest (KOIs) exhibit significant TTVs, but KOI-142.01 stands out among them with an unrivaled, 12-hour TTV amplitude. Here we report a thorough analysis of KOI-142.01's transits. We discover periodic Transit Duration Variations (TDVs) of KOI-142.01 that are nearly in phase with the observed TTVs. We show that KOI-142.01's TTVs and TDVs uniquely detect a non-transiting companion with a mass 0.7 that of Jupiter (KOI-142c). KOI-142.01's mass inferred from the transit variations is consistent with the measured transit depth, suggesting a Neptune class planet (KOI-142b). The orbital period ratio P_c/P_b=2.03 indicates that the two planets are just wide of the 2:1 resonance. The present dynamics of this system, characterized here in detail, can be used to test various formation theories that have been proposed to explain the near-resonant pairs of exoplanets
