A Preliminary Study of DSM–5 PTSD Symptom Patterns in Veterans by Trauma Type

The all-volunteer status of the military, combined with an increasing desire to employ individuals with the requisite knowledge, skills, and abilities to perform highly sophisticated tasks, has intensified competition between military and private sector organizations attempting to attract and retain qualified personnel. In an effort to remain competitive with employers in the private sector labor market, U.S. military organizations have directed their attention to various personnel support programs aimed at meeting the needs of servicemembers and contributing to their overall quality of life. More specifically, these military services have focused on the development and validation of conceptual models that link quality of life to desired military outcomes, including personnel retention, readiness, and performance. This study extended recent quality of life research efforts by determining the applicability of a model developed and validated for Navy personnel to another branch of the military, the U.S. Marine Corps. Structural equation modeling results suggested that the Navy model provided an adequate fit to the Marine Corps data for each of the subgroups considered. Results and implications are discussed.     

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.     

A new orthorhombic approximant of the icosahedral Al–Cu–Fe quasicrystal

We report on the formation of a new crystalline approximant phase of the icosahedral (i-)Al–Cu–Fe quasicrystal. This phase is formed during sintering of Al-based composites reinforced with i-AlCuFeB quasicrystalline particles. The structure of this phase has been characterized by transmission electron microscopy (TEM) and high-resolution electron microscopy (HREM). TEM revealed that it is a B-centred orthorhombic phase with lattice parameters a = 1.166 nm, b = 1.195 nm and c = 3.44 nm. Its chemical composition, as determined by electron energy loss spectroscopy (EELS), is close to Al_76.9Cu_2.7Fe_20.4, with an average number of valence electrons per atom e/a of 1.92, similar to the value in all other approximants of the i-phase discovered thus far. Initial results on local atomic arrangements along one of its pseudo-5-fold axes are also presented.
