    Abstract The accurate identification of persons at risk of exiting permanent supportive housing could help maximize client success and minimize attrition and premature exits from such housing. Thus, in the present study, we developed and tested multivariable prediction models of negative and positive exits from the U.S. Department of Housing and Urban Development-Veterans Affairs Supportive Housing (HUD-VASH) program using logistic regression and random forests. We compared the performance of these models with clinical predictions made by HUD-VASH program case managers. We selected a cohort of all 92,196 Veterans who entered HUD-VASH nationwide between October 1, 2014 and September 30, 2019, 70% of whom were randomly selected to serve as the development cohort and the remaining 30% of whom served as the validation cohort. Negative and positive exits were measured until September 30, 2019. A subset of 1,264 Veterans was used to compare performance of models with clinical judgment. Predictor variables included sociodemographic characteristics, health and behavioral health diagnoses, homeless/housing history, and VA service utilization history. Performance of models and clinical judgment were assessed using an array of metrics including area under the receiver operating characteristic curve (AUROC), sensitivity, specificity, and positive predictive value. The logistic regression and random forest models had similar, modest performance in predicting negative and positive exits. These models were substantially more sensitive, yet far less specific in predicting exits than clinician ratings. Study findings highlight the challenges and tradeoffs in using actuarial models or case manager predictions to target interventions to Veterans at risk of exiting HUD-VASH.

    Abstract We reported exciton binding-energy determination using tunneling-current spectroscopy of Germanium (Ge) quantum dot (QD) single-hole transistors (SHTs) operating in the few-hole regime, under 405-1550 nm wavelength (λ) illumination. When the photon energy is smaller than the bandgap energy (1.46 eV) of a 20 nm Ge QD (for instance, λ = 1310 nm and 1550 nm illuminations), there is no change in the peak voltages of tunneling current spectroscopy even when the irradiation power density reaches as high as 10 µW/µm

    Abstract Background: Positive affect (PA) attenuates negative reactivity to stress; however, this adaptive function of PA is seldom studied in psychiatric conditions characterized by more extreme forms of affective responding. We tested distinct associations of PA and negative affect (NA) with anxiety reactivity in participants with social anxiety disorder (SAD)-a condition characterized by heightened NA and diminished PA-and non-SAD control subjects.
    Method: Adults with a principal diagnosis of SAD (n = 71) and those without a psychiatric history (n = 36) rated their PA and NA during the past week, and were exposed to a laboratory stressor wherein they delivered a video-recorded speech on a controversial topic. Anxiety reactivity was assessed in terms of anticipatory anxiety prior to the speech, and observer-rated anxiety-related behavior during the speech.
    Results: Across all participants, higher PA significantly predicted lower anticipatory anxiety and less anxiety-related behavior, beyond level of NA; lower NA significantly predicted attenuated anticipatory anxiety, but not anxiety-related behavior, beyond level of PA. The association between PA and stress reactivity was diminished for individuals with especially elevated NA, as well as for individuals with SAD compared to those without.
    Conclusions: PA may be protective against negative reactivity to social stress; however, theoretical models and clinical applications should consider possible interactive effects of PA and NA in modulating stress reactivity.
