Sexual compulsivity, erectile dysfunction, and suicidality among male survivors of military sexual violence
Although military sexual trauma (MST) is associated with an increased risk of suicide, suicide attempts, and suicidal ideation among service members and veterans, there is limited knowledge regarding the mechanisms of MST and suicidality among men. The current study examined whether MST was associated with sexual compulsivity and/or erectile dysfunction and if these, in turn, explained elevated suicidal thoughts and the likelihood of engaging in future suicidal behavior after accounting for mental health, military, and demographic characteristics. Servicemembers and veteranswho reported their gender as male (N = 508) were recruited via social media and completed online self-report measures assessing MST, erectile dysfunction, sexual compulsivity, suicidal ideation frequency, and the likelihood of engaging in future suicidal behavior. Path analysis was used to examine the study hypotheses. In total, 67 participants (13.2%) reported a history of MST; of these individuals, 27 (40.3%) reported suicidal ideation in the past 12 months, and 29 (43.9%) reported an increased likelihood of engaging in future suicidal behavior. MST was associated with increased sexual compulsivity, which, in turn, predicted more frequent suicidal ideation as well as a higher self-reported likelihood of engaging in future suicidal behavior. MST was associated with higher levels of erectile dysfunction, but erectile dysfunction was not associated with suicidal ideation in the adjusted model. Although the data were cross-sectional, precluding determinations of causality, the results support assessing and intervening with regard to sexual compulsivity tomitigate the risk for suicide-related outcomes among men who experience MST
The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficiently to enable an affordable space-based telescope mission capable of discovering and characterizing Earthlike planets orbiting nearby bright sunlike stars in order to search for signs of habitability and biosignatures. Such a mission can also be equipped with instrumentation that will enable broad and exciting general astrophysics and planetary science not possible from current or planned facilities. HabEx is a space telescope with unique imaging and multi-object spectroscopic capabilities at wavelengths ranging from ultraviolet (UV) to near-IR. These capabilities allow for a broad suite of compelling science that cuts across the entire NASA astrophysics portfolio. HabEx has three primary science goals: (1) Seek out nearby worlds and explore their habitability; (2) Map out nearby planetary systems and understand the diversity of the worlds they contain; (3) Enable new explorations of astrophysical systems from our own solar system to external galaxies by extending our reach in the UV through near-IR. This Great Observatory science will be selected through a competed GO program, and will account for about 50% of the HabEx primary mission. The preferred HabEx architecture is a 4m, monolithic, off-axis telescope that is diffraction-limited at 0.4 microns and is in an L2 orbit. HabEx employs two starlight suppression systems: a coronagraph and a starshade, each with their own dedicated instrument
