    Abstract: This study compares the utility of two measures of psychopathic traits, the Antisocial Features (ANT) scale of the Personality Assessment Inventory and the Psychopathy Checklist—Revised (PCL-R), to predict serious institutional misconduct among incarcerated sex offenders over a 2-year follow-up period. Archival disciplinary data for 58 offenders were classified as major infractions involving physical aggression, verbal aggression/acts of defiance, or nonaggressive offenses. Significant correlations were obtained between both measures of psychopathy and each type of disciplinary offense except physical aggression, the occurrence of which was rare in this sample. Regression analyses indicated that each measure accounted for unique—or incremental—variance in one of the criterion measures. Overall classification accuracy based on standard cut scores was somewhat more positive for ANT than for the PCL-R.

    Impact of 30-Day Oral Dosing with N -acetyl- l -cysteine on Sprague-Dawley Rat Physiology

    Abstract: A number of studies have demonstrated a protective effect associated with N-acetyl-l-cysteine (NAC) against toxic chemical exposure. However, the impact of long-term oral dosing on tissue pathology has not been determined. In this study, the authors assessed the impact of long-term oral NAC administration on organ histopathology and tissue glutathione (GSH) and total glutathione- S-transferase (GST) activity levels in Sprague-Dawley (SD) rats. Groups of 20 SD rats (10 males, 10 females), 8 weeks of age, were dosed daily by oral gavage with deionized H 2 O (negative controls) or NAC solution at a rate of 600 or 1200 mg/kg/day for 30 days. Animals were euthanized 6 h after treatment on study day 30. There were no significant differences in final body weights or weekly average weight gain between treatment groups. Serum alanine amino-transferase (ALT) activities were significantly elevated ( p ≤.05) in NAC-treated animals compared to controls when measured on study day 30. Histopathologic evaluation of the stomach, small intestine, liver, kidneys, spleen, thymus, and lungs revealed no lesions associated with NAC administration. When measured on study day 30, total GST activity for kidney and skin from NAC-treated animals were increased 39% to 131% as compared to controls. Tissue GSH concentrations from NAC-treated animals were increased 24% to 81% as compared with negative controls. Further studies are needed to determine if the observed increase in tissue GSH concentration and GST activity provide a degree of chemoprotection against dermal and systemic chemical toxicants.

    The Limits of Transparent Depth Perception with Restricted Field of View: Application in an Augmented Reality Surgical Microscope
    SAGE Publications ; 2001

    Abstract: This paper describes an investigation into the effect of reduced field of view and target size in transparent stereo augmented reality systems. Six subjects were asked to identify the maximum disparity limit of correct 3D perception for a random dot target of different sizes, viewed through a transparent scene with a varying field of view (FOV). The results showed that the maximum disparity limit increased linearly up to 25 degrees FOV after which it showed no significant increase for increasing FOV. There was no significant difference in the maximum disparity values obtained using a 4, 8, or 10 degree target. The maximum disparity limit of 5.9 ±1 (mean ± SD) degrees visual angle was used in an equation to predict the range in which correct depth perception occurs for transparent AR in a binocular surgical microscope. We suggest that the optimum image position to give the greatest range for correct 3D depth perception is 25cm when viewing transparent targets behind a transparent real scene.

    Nuclear enterprise performance measurement

    Abstract: The criticality of the United States Air Force nuclear enterprise demands that commanders have the best possible understanding of system performance, both in the aggregate and at the drill-down levels, sufficient to make timely corrective actions when warranted. We propose a new strategy-linked measurement system for nuclear enterprise sustainment, which includes a set of performance metrics and a new Aggregation h method for aggregating the metrics. Our metrics use United States Air Force approved or adapted metrics that accommodate weighting and enable performance comparisons between organizations or performance within the same organization over time. We demonstrate our method with generated performance data designed to test the sensitivity of our method. Our Aggregation h method provides a simple, intuitive measurement approach that enables unity of effort and influences behavior at each hierarchical level towards achieving strategic goals, and is extendable to performance measurement for other complex sustainment systems.

    Relationship Between the Risk of Suffering a First-Time Noncontact ACL Injury and Geometry of the Femoral Notch and ACL : A Prospective Cohort Study With a Nested Case-Control Analysis

    Abstract: The morphometric characteristics of the anterior cruciate ligament (ACL) and the femoral intercondylar notch within which it resides have been implicated as risk factors for injuries to this important stabilizer of the knee. Prior research has produced equivocal results with differing methodologies, and consequently, it is unclear how these characteristics affect the injury risk in male and female patients. Hypothesis: The morphometric characteristics of the ACL and femoral intercondylar notch are individually and independently associated with the risk of suffering a noncontact ACL injury, and these relationships are different in male and female patients. Study Design: Case-control study; Level of evidence, 3. Methods: Magnetic resonance imaging scans of the bilateral knees were obtained on 88 case-control pairs (27 male, 61 female) matched for age, sex, and participation on the same sports team. Patients had suffered a grade III, first-time, noncontact ACL tear. The femoral notch width at 4 locations, the thickness of the bony ridge at the anteromedial outlet of the femoral notch, the femoral notch volume, ACL volume, and ACL cross-sectional area were measured. Results: Multivariate analysis of combined data from male and female patients revealed that decreased ACL volume (odds ratio [OR], 0.829), decreased femoral notch width (OR, 0.700), and increased bony ridge thickness at the anteromedial outlet of the femoral notch (OR, 1.614) were significant independent predictors of an ACL injury. Separate analyses of male and female patients indicated that the femoral notch ridge may be more strongly associated with a risk in female patients, while ACL volume is more strongly associated with a risk in male patients. However, statistical analysis performed with an adjustment for body weight strengthened the association between ACL volume and the risk of injuries in female patients. Conclusion: Morphometric features of both the ACL and femoral notch combine to influence the risk of suffering a noncontact ACL injury. When included together in a multivariate model that adjusts for body weight, the effects of the morphometric measurements are similar in male and female patients. If body weight is not taken into consideration, ACL volume is not associated with a risk in female patients.
