Deriving Dg Categories
, 1993
"... We investigate the (unbounded) derived category of a differential Zgraded category (=DG category). As a first application, we deduce a 'triangulated analogue` (4.3) of a theorem of Freyd's [5, Ex. 5.3 H] and Gabriel's [6, Ch. V] characterizing module categories among abelian categori ..."

Selfconcordance at work: Toward understanding the motivational effects of transformational leaders.
 Academy of Management Journal,
, 2003
"... We extend existing theories by linking transformational leadership to "selfconcordance" at work. In two studies using diverse samples and methods, leader behaviors were associated with follower tendencies to set selfconcordant goals. In general, followers of transformational leaders vie ..."

Violence and risk of PTSD, major depression, substance abuse/ dependence, and comorbidity: results from the National Survey of Adolescents. J Consult Clin Psychol
"... With a national household probability sample of 4,023 telephoneinterviewed adolescents ages 12–17, this study provides prevalence, comorbidity, and riskfactor data for posttraumatic stress disorder (PTSD), major depressive episode (MDE), and substance abuse/dependence (SA/D).
