  Title Rising From the Ashes: Cognitive Determinants of Venture Growth After Entrepreneurial Failure Type Journal Article
  Year 2015 Publication Entrepreneurship Theory and Practice Abbreviated Journal Entrepreneurship Theory and Practice  
  Volume 39 Issue 2 Pages 209-236  
  Keywords (up)  
  Abstract How does previous entrepreneurial failure influence future entrepreneurship? More specifically, under what conditions do entrepreneurs who rebound from failure do better in the next round? Drawing on the cognitive literature in attribution and motivation, we focus on entrepreneurs' reaction to failure and the growth of their subsequent ventures. Leveraging a survey database of new-venture founders with failure experiences, we investigate how their internal attribution of the cause of failure, their intrinsic motivation to start up another business after failure, and the extent of their failure experiences impact the growth of their subsequent ventures.

  Title Spitzer-IRS Spectroscopic Studies of Oxygen-Rich Asymptotic Giant Branch Star and Red Supergiant Star Dust Properties Type Conference Article
  Year 2015 Publication Abbreviated Journal  
  Volume Issue Pages 216.03-216.03  
  Keywords (up)  
  Abstract We analyze the dust emission features seen in Spitzer Space Telescope Infrared Spectrograph (IRS) spectra of Oxygen-rich (O-rich) asymptotic giant branch (AGB) and red supergiant (RSG) stars. The spectra come from the Spitzer Legacy program SAGE-Spectroscopy (PI: F. Kemper) and other archival Spitzer-IRS programs. The broad 10 and 20 micron emission features attributed to amorphous dust of silicate composition seen in the spectra show evidence for systematic differences in the centroid of both emission features between O-rich AGB and RSG populations. Radiative transfer modeling using the GRAMS grid of models of AGB and RSG stars suggests that the centroid differences are due to differences in dust properties. We present an update of our investigation of differences in dust composition, size, shape, etc that might be responsible for these spectral differences. We explore how these differences may arise from the different circumstellar environments around RSG and O-rich AGB stars. BAS acknowledges funding from NASA ADAP grant NNX13AD54G.

  Title Dust and metallicity in carbon stars Type Conference Article
  Year 2015 Publication Abbreviated Journal  
  Volume Issue Pages 216.04-216.04  
  Keywords (up)  
  Abstract The Infrared Spectrograph on the Spitzer Space Telescope observed over 200 carbon stars in nearby metal-poor dwarf galaxies. These spectra probe how the quantity and composition of dust produced by carbon stars depend on initial metallicity, initial mass, and pulsational properties. For stars to produce significant quantities of dust, they must be pulsating in the fundamental mode with strong amplitudes. The spectra confirm that carbon stars with longer pulsation periods produce more dust and that the amount of dust shows no strong dependence on metallicity. This sample includes more carbon stars with low mass and reveals that for a given pulsation period, higher-mass stars produce less dust. Evidence is building for the layering of dust grains, with SiC cores in grains produced by metal-rich carbon stars, and mantles of MgS around grains in all embedded stars.

  Title The Symptoms of Trauma Scale (SOTS): An Initial Psychometric Study Type Journal Article
  Year 2015 Publication Journal of Psychiatric Practice Abbreviated Journal J Psychiatr Pract  
  Volume 21 Issue 6 Pages 474-483  
  Keywords (up)  
  Abstract The Symptoms of Trauma Scale (SOTS) is a 12-item, interview-based, clinician-rated measure that assesses the severity of a range of trauma-related symptoms. This pilot study evaluated its use and psychometric properties in an outpatient setting that provides treatment to survivors of chronic interpersonal trauma. Thirty participants completed self-report measures of posttraumatic stress symptoms, depression, dissociation, self-esteem, and affect dysregulation; the participants also participated separately in a semistructured interview based on the SOTS conducted by 2 trained interviewers. SOTS composite severity scores for DSM-IV posttraumatic stress disorder (PTSD) and complex PTSD (cPTSD), DSM-5 PTSD, and PTSD dissociative subtype, and total traumatic stress symptoms generally had acceptable internal consistency and interrater reliability. Evidence of convergent, discriminant, criterion, and construct validity was found for the SOTS composite PTSD scores, although potential limitations to validity that require further research and refinement of the measure were identified for the SOTS total and DSM-IV cPTSD scores and the hyperarousal, affect dysregulation, and dissociation items. Interviewers and interviewees described the interview as efficient, informative, and well tolerated. Implications for clinical practice and research to refine the SOTS are discussed.

  Title Investigating the dissociative subtype of posttraumatic stress disorder in a sample of traumatized detained youth Type Journal Article
  Year 2015 Publication Psychological Trauma : Theory, Research, Practice and Policy Abbreviated Journal Psychol Trauma  
  Volume 7 Issue 5 Pages 465-472  
  Keywords (up)  
  Abstract In this study, we tested the validity of a dissociative subtype in a sample of 225 detained adolescents (142 boys, 83 girls) likely meeting full or partial criteria for posttraumatic stress disorder (PTSD). Competing theories of dissociation pose controversy regarding dissociation as a taxon versus a continuum, and results of the current study contribute to this debate by providing evidence of distinct group differences between those high and low in dissociation. Mixture modeling revealed 2 groups of youth with differing levels of depersonalization/derealization dissociative symptoms. Differences between the 2 groups of youth were investigated regarding trauma exposure and several posttraumatic reactions: posttraumatic stress symptoms (PTSS), emotion dysregulation, and emotional numbing. Compared with youth classified in the low-dissociation group, youth who exhibited high levels of dissociation demonstrated higher levels of total PTSS, posttraumatic symptom clusters of emotional numbing, intrusion, and associated features, as well as reporting more difficulties with emotion dysregulation. To test theory regarding the factors that increase the likelihood of persistent dissociation, bootstrapped regression analyses were performed to examine the possibility of an indirect effect of peritraumatic dissociation. Results consistent with statistical mediation suggested that the presence of peritraumatic dissociation at the time of trauma may contribute to the continuation of dissociative symptoms as a more generalized pattern. The results of the current study have implications for clinical treatment with traumatized youth.

  Title Evaluating the dimensionality of PTSD in a sample of OIF/OEF veterans Type Journal Article
  Year 2015 Publication Psychological Trauma : Theory, Research, Practice and Policy Abbreviated Journal Psychol Trauma  
  Volume 7 Issue 5 Pages 430-436  
  Keywords (up)  
  Abstract Both categorical and dimensional models of mental disorders, including posttraumatic stress disorder (PTSD), are useful for diagnostic and heuristic purposes; however, few empirical studies have compared categorical and dimensional models of PTSD side-by-side or compared these models to a hybrid (dimensional and categorical) model. In the present study, the dimensionality of PTSD was examined by fitting latent profile analytic, confirmatory factor analytic, and factor mixture models in 271 Operation Iraqi Freedom/Operation Enduring Freedom veterans 6 months after return from deployment. Latent profile analysis was used to identify subgroups of individuals with similar PTSD symptom profiles and predictors of subgroup membership, confirmatory factor analysis was used to identify the underlying continuous structure of PTSD in this sample, and factor mixture modeling was used to test whether a hybrid categorical and continuous model of PTSD best fit our sample. A factor mixture model consisting of a 4-factor dysphoria model of PTSD with 2 classes characterized by low and moderate symptom severity was the best-fitting model. Dissociation and deployment concerns emerged as significant predictors of membership in the moderate symptoms class. Implications for PTSD diagnostic conceptualization and treatment planning are discussed.

  Title The Dissociative Subtype of Posttraumatic Stress Disorder: Unique Resting-State Functional Connectivity of Basolateral and Centromedial Amygdala Complexes Type Journal Article
  Year 2015 Publication Neuropsychopharmacology : Official Publication of the American College of Neuropsychopharmacology Abbreviated Journal Neuropsychopharmacology  
  Volume 40 Issue 10 Pages 2317-2326  
  Keywords (up)  
  Abstract Previous studies point towards differential connectivity patterns among basolateral (BLA) and centromedial (CMA) amygdala regions in patients with posttraumatic stress disorder (PTSD) as compared with controls. Here we describe the first study to compare directly connectivity patterns of the BLA and CMA complexes between PTSD patients with and without the dissociative subtype (PTSD+DS and PTSD-DS, respectively). Amygdala connectivity to regulatory prefrontal regions and parietal regions involved in consciousness and proprioception were expected to differ between these two groups based on differential limbic regulation and behavioral symptoms. PTSD patients (n=49) with (n=13) and without (n=36) the dissociative subtype and age-matched healthy controls (n=40) underwent resting-state fMRI. Bilateral BLA and CMA connectivity patterns were compared using a seed-based approach via SPM Anatomy Toolbox. Among patients with PTSD, the PTSD+DS group exhibited greater amygdala functional connectivity to prefrontal regions involved in emotion regulation (bilateral BLA and left CMA to the middle frontal gyrus and bilateral CMA to the medial frontal gyrus) as compared with the PTSD-DS group. In addition, the PTSD+DS group showed greater amygdala connectivity to regions involved in consciousness, awareness, and proprioception-implicated in depersonalization and derealization (left BLA to superior parietal lobe and cerebellar culmen; left CMA to dorsal posterior cingulate and precuneus). Differences in amygdala complex connectivity to specific brain regions parallel the unique symptom profiles of the PTSD subgroups and point towards unique biological markers of the dissociative subtype of PTSD.

  Title Posttraumatic stress in deployed Marines: prospective trajectories of early adaptation Type Journal Article
  Year 2015 Publication Journal of Abnormal Psychology Abbreviated Journal J Abnorm Psychol  
  Volume 124 Issue 1 Pages 155-171  
  Keywords (up)  
  Abstract We examined the course of PTSD symptoms in a cohort of U.S. Marines (N = 867) recruited for the Marine Resiliency Study (MRS) from a single infantry battalion that deployed as a unit for 7 months to Afghanistan during the peak of conflict there. Data were collected via structured interviews and self-report questionnaires 1 month prior to deployment and again at 1, 5, and 8 months postdeployment. Second-order growth mixture modeling was used to disaggregate symptom trajectories; multinomial logistic regression and relative weights analysis were used to assess the role of combat exposure, prior life span trauma, social support, peritraumatic dissociation, and avoidant coping as predictors of trajectory membership. Three trajectories best fit the data: a low-stable symptom course (79%), a new-onset PTSD symptoms course (13%), and a preexisting PTSD symptoms course (8%). Comparison in a separate MRS cohort with lower levels of combat exposure yielded similar results, except for the absence of a new-onset trajectory. In the main cohort, the modal trajectory was a low-stable symptoms course that included a small but clinically meaningful increase in symptoms from predeployment to 1 month postdeployment. We found no trajectory of recovery from more severe symptoms in either cohort, suggesting that the relative change in symptoms from predeployment to 1 month postdeployment might provide the best indicator of first-year course. The best predictors of trajectory membership were peritraumatic dissociation and avoidant coping, suggesting that changes in cognition, perception, and behavior following trauma might be particularly useful indicators of first-year outcomes.
