Leadership and Perceiver Cognition: Examining the Role of Self-Identity in Implicit Leadership Theories

We investigated whether priming individuals' self-identities to be interdependent or independent influences their ratings of leadership prototypicality. Specifically, we predicted that participants receiving an interdependent prime would rate items associated with transformational leadership as being more prototypical of effective leadership than would participants receiving no prime. We also predicted that participants receiving an independent prime would rate transactional leadership items as being more prototypical of effective leadership. Undergraduate psychology students were randomly assigned to one of three conditions (interdependent prime, independent prime, and control). Results support the idea that self-identity can be primed to influence ratings of leadership prototypicality. We discuss implications and suggest directions for future research.     

Mediation of Cognitive Appraisal on Combat Exposure and Psychological Distress

Applying Cognitive Appraisal Theory (Lazarus &; Folkman, 1984 Lazarus, R. S. and Folkman, S. 1984. Stress, appraisal, and coping, New York, NY: Springer Publishing Company.  [Google Scholar]), this study sought to determine the mediating effect of cognitive appraisal on combat exposure and psychological distress. A total of 3,002 military personnel completed measures of combat exposure, cognitive appraisal of combat-related events, and psychological distress either during or soon after combat operations in Afghanistan. Bootstrapping was employed to test the mediation model. Cognitive appraisal mediated the relationship between combat exposure and psychological distress, suggesting that the impact of a potentially stressful event on well-being is contingent on one's appraisal of that event. Implications for future research and training are presented.     

Characteristics and Correlates of Cigarette Use Among Recent U.S. Veterans

Little is known about the smoking habits and cessation efforts of veterans returning from Iraq and Afghanistan, many of whom will seek health care services in the public sector. This project documents rates of smoking and quit attempts among veterans receiving Veteran's Health Administration (VHA) health care and describes the relationship between current smoking use/cessation and demographic characteristics, quality of life, and potential alcohol misuse.

A large representative sample of Iraq/Afghanistan era veterans was surveyed using the VA Survey of Healthcare Experiences of Patients (Wright, Craig, Campbell, Schafer, &; Humble, 2006 Wright, S. M., Craig, T., Campbell, S., Schaefer, J. and Humble, C. 2006. Patient satisfaction of female and male users of Veterans Health Administration services. Journal of General Internal Medicine, 21(Suppl. 3): S26–S32. [Crossref], [PubMed] , [Google Scholar]). One third of respondents reported smoking during the past year and 24% reported currently smoking. Current smoking status was more prevalent among those who reported less education and lower household income. Current smoking status was also related to lower mental and physical health quality of life and higher potential alcohol misuse scores. Quit attempts were significantly less common among reserve component veterans and quitters reported higher incomes and were slightly older. The frequency of cigarette smoking among recent veterans underscores the importance of addressing smoking cessation efforts within this population. Individual characteristics associated with current smoking, cessation efforts, and relapse may help tailor cessation treatment for this growing cohort of new veterans.     

The Performance of the AUDIT-C and the Examination of Risks Associated With Postdeployment Alcohol Misuse in Air Force Medical Service Personnel

This study assessed the performance of the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) in diagnosing a postdeployment alcohol disorder in a cohort of Air Force Medical Services personnel (N = 13,353). The prevalence of alcohol disorders in this population of previously deployed military healthcare personnel was 1.26% based on medical record data. Assessing the AUDIT-C as a screening tool, the following characteristics were found: sensitivity was 23.81%, specificity was 91.48%, positive predictive value was 3.44%, and negative predictive value was 98.95%. The positive and negative likelihood ratios were 2.80 and 0.83, respectively. Classification accuracy of the AUDIT-C was improved by accounting for officer status and female gender. The area under the receiver operating characteristic curve was 0.69 for the multivariable model, indicating poor to fair classification accuracy. However, this model was significantly improved over the univariate model. Thus, taking rank and gender into account when conducting screening may improve the utility of the AUDIT-C.     

A Systematic Review of the Biopsychosocial–Spiritual Health of Active Duty Women

Women make up approximately 15% of today’s active duty (AD) military. Not only are more women volunteering for military service now than ever before in America’s history, but due to recent policy changes, they are also allowed to apply for more jobs. Therefore, since the number of women in the military is continuing to rise and there are more job opportunities for women in the military, it is important to understand the unique health effects they experience that differ from civilian women and AD males. Although there is current literature on the biological, psychological, social, and spiritual health of veteran women, few researchers have explored the biopsychosocial–spiritual effects of military service on AD women. Thus, the purpose of this systematic review was to explore the existing research on the biopsychosocial–spiritual health factors associated with military service in AD women. The results of this study indicated that there is more data on the biological health compared to the psychological and social health of AD women. There is even less research demonstrating the interconnectedness among biological, psychological, social, and spiritual health with AD women. Future research recommendations and policy implications are provided.     

The Performance of the PHQ-2 and the Examination of Risks Associated With Postdeployment Depression in Air Force Medical Service Personnel

This study assessed the performance of the 2-item Patient Health Questionnaire (PHQ-2) in identifying postdeployment depressive disorders in a cohort of Air Force Medical Services personnel (N = 18,398). The prevalence of depressive disorders in the cohort was 9.00% based on medical record data. The area under the receiver operating characteristic curve was 0.56, indicating very poor classification accuracy. Sensitivity was 15.53%, specificity was 95.57%, positive predictive value was 25.75%, and negative predictive value was 91.97%. The positive and negative likelihood ratios were 3.51 and 0.88, respectively. Several risk factors associated with postdeployment depressive disorders were identified that could potentially improve screening in this population.     

Frequency of Scale Elevations and Factor Structure of the Behavior Rating Inventory of Executive Function (BRIEF) in Children and Adolescents With Intractable Epilepsy

The Behavior Rating Inventory of Executive Function (BRIEF) is a standardized rating scale that provides information about the nature and extent of executive function deficits displayed by children and adolescents in daily life. BRIEF protocols completed by parents of 80 children with intractable epilepsy were evaluated with respect to prevalence and severity of scale elevations in the sample, and also with respect to factor structure. Overall, the sample was rated as having significantly more executive function problems than healthy children in the BRIEF standardization sample; elevations on the Working Memory and Plan/Organize scales were most frequently seen. Fully 36% of the sample had four or more significantly elevated scales. However, 31% of the sample had no clinically elevated scales, indicating that executive difficulties, though frequent, are not necessarily characteristic of all children with severe epilepsy. As in the validation studies reported in the manual, a two-factor solution emerged from a principal factor analysis of BRIEF scales. However, the factor structure as given in the manual was not entirely replicated; specifically, the Monitor scale was found to load equivalently on both factors. The results of this study suggest that a substantial proportion of children with intractable epilepsy display significant executive function deficits in daily life. Research into the relationship of BRIEF scores to other measures of executive functioning in children with epilepsy is needed to further clarify its clinical utility.     

Hydrogenation of Ti50Zr25Co25 amorphous ribbons and its effect on their structural and mechanical properties

Changes in the structure and mechanical properties of Ti₅₀Zr₂₅Co₂₅ melt-spun ribbons upon electrolytic hydrogenation have been investigated. Structural analyses of the as-spun ribbons revealed the sporadic presence of icosahedral (i) quasicrystalline short-range order (SRO) in the amorphous structure. Upon cathodic charging with hydrogen, the i-SRO vanished for a hydrogen content of about 21 at.% (hydrogen-to-metal atom ratio, H/M: 0.26), resulting in a fully amorphous structure. Simultaneously, the fracture strength was found to increase while the ribbons preserved their bending ductility. However, a significant reduction in the fracture strength and ductility of the ribbons was observed for hydrogen concentrations larger than 26 at.%. Variations in the mechanical stability are discussed based on a structure-property correlation.     

Prediction of termination migration of a rod-type particle in Ti–6Al–4Fe alloy

The kinetics for the termination migration of a rod-type alpha particle in a two-phase Ti alloy was predicted on the basis of the edge recession theory. The developed model quantified the effect of geometrical dimensions and diffusional factors on the spheroidization rate. Comparison with the experimental results of Ti–6Al–4Fe showed that the model can provide a reasonable prediction of the time to complete the static spheroidization of rod-type particles.     

Effect of a nanoporous surface on photoluminescence from nanopatterned GaN thin films fabricated by anodic alumina templates

GaN photonic crystal slabs on InGaN/GaN multi-quantum well light-emitting diodes have been formed by dry etching using nanoporous anodic alumina templates, which have a periodic lattice constant of 105 nm and a hole diameter of 45 nm. The photonic crystal slab shows an enhanced intensity of photoluminescence due to the nanohole pattern array producing Fabry–Perot like interference. A rough surface of nanoholes results in a broad spectrum with a small oscillation, and well-ordered multiple facets of nanoholes results in a relatively sharp spectrum with a large oscillation.
