During the civil war between Caesar and Pompey, the military oath which binds the soldier to his army is often openly violated. Yet despite this offense, commanders of armed struggle require recursively the oath to their men. Admittedly, this ritual act seems ineffective given the many desertions and mutinies identified, but military leaders use its symbolic and sacred meaning to legitimize one hand their “anti-republican” actions, on the other armies fighting in a context deemed impius.

The integration of cultural elements into the operational planning process is a complex task that requires practical and theroretical tools for a wide comprehension of the context to help solve the problem. This article shows the results of an empirical research which presents conflicting cultural factors as the starting point for the construction of mediating structures. The main result of our research is a partial cognitive structure, a system of ideas, represented in a template listing the basic conflictive factors at the tactical level that military could find in the development of their tasks. The template is also a valuable aid to design military training curricula and to be applied to any post-conflict stability operation in complex environments resulting from irregular or asymmetric conflicts.

Since America’s beginnings as a British colony, its musical standards have adhered to those of Western Europe. For this reason, musical forms native to America like Black folk spirituals and Gospel music have historically been marginalized in favor of music in the Western classical tradition. Today, a bias towards music of the Western classical tradition exists in those American universities that grant music degrees. While this bias is understandable, inclusion of Gospel music history and performance practice would result in a more complete understanding of American music and its impact on American nationalism. The United States Naval Academy is one of the few American universities that have consistently elevated the performance of Gospel music to the level of Western Classical music within its institutional culture. The motivations for writing this document are to provide a brief history of Gospel music in the United States and of choral music at the Naval Academy. These historical accounts serve as lenses though which the intersection of Gospel music performance practice and leadership development at the United States Naval Academy may be observed. During the last two decades of the twentieth century, Gospel music intersected American military culture at the U.S. Naval Academy. After a few student-led attempts in the 1970s, a Gospel Choir was formed in 1986 but by 1990, it had become an official part of the Music Department. Ultimately, it received institutional support and today, the Gospel Choir is one of three touring choirs authorized to represent the Academy in an official capacity. This document discusses the promotion of Gospel music by the Naval Academy in its efforts to diversify Academy culture and ultimately, Naval and Marine Corps leadership. Finally, this dissertation examines the addition of performed cultural expression (Gospel music) in light of a shift in American nationalism and discusses its impact on Naval Academy culture.

To ensure mission-readiness for military members, support for their families is essential. Military family health and health care satisfaction has been a neglected area of study in this population. Satisfaction can be defined in terms of patient-, provider-, and practice-level factors and is influenced by continuity of care, which is often poor in transient military populations. Using a modified patient satisfaction survey, this study found that both the number of moves and assigned providers were significantly associated with continuity of care in military spouses. Further, continuity of care was a significant predictor of satisfaction with military health care.

Why do states facing high levels of international threat sometimes have militaries that are heavily involved in politics and at other times relatively apolitical, professional militaries? I argue that the answer to this puzzle lies in a state's history of 'acute' international crises rather than its 'chronic' threat environment. Major international crises lead to professionalization and de-politicization of militaries in both the short- and long-term. International crises underscore the need for the military to defend the state and highlight military deficiencies in this regard. Accordingly, major international crises lead to military professionalization and withdrawal from politics in order to increase military effectiveness. This effect persists years, and decades, later due to generational shifts in the officer corps. As the "Crisis Generation" of officers become generals, they bring with them a preference for professionalization and de-politicization. They guide the military towards abstention from politics. I test this theory using a new global dataset on military officers in national governing bodies from 1964-2008 and find strong support for the theory. Major international crises lead to two waves of military withdrawal from government, years apart. Further statistical analysis finds that this effect is most strongly felt in the non-security areas of governing, while in some cases, international crises may lead to militaries increasing their involvement in security policy-making. Further, international crises that end poorly for a state — i.e., defeats or stalemates — are found to drive more rapid waves of military withdrawal from government. The statistical analysis is supported by a case illustration of civil-military relations in the People's Republic of China, which demonstrates that the crisis of the Korean War (1950-53) led to two waves of military professionalization and de-politicization, decades apart. The first occurred immediately after the war. The second wave, occurring in the 1980s, involved wholesale military withdrawal from governing bodies, which was made possible by the ascent of the "Crisis Generation" of officers in the military, who had served as junior officers in the Korean War, decades prior.

The goal of the thesis "Conversion of a Micro, Glow-Ignition, Two-Stroke Engine from Nitromethane-Methanol Blend Fuel to Military Jet Propellant (JP-8)" was to demonstrate the ability to operate a small engine on JP-8 and was completed in two phases. The first phase included choosing, developing a test stand for, and baseline testing a nitromethane-methanol-fueled engine. The chosen engine was an 11.5 cc, glow-ignition, two-stroke engine designed for remote-controlled helicopters. A micro engine test stand was developed to load and motor the engine. Instrumentation specific to the low flow rates and high speeds of the micro engine was developed and used to document engine behavior. The second phase included converting the engine to operate on JP-8, completing JP-8-fueled steady-state testing, and comparing the performance of the JP-8-fueled engine to the nitromethane-methanol-fueled engine. The conversion was accomplished through a novel crankcase heating method; by heating the crankcase for an extended period of time, a flammable fuel-air mixture was generated in the crankcase scavenged engine, which greatly improved starting times. To aid in starting and steady-state operation, yttrium-zirconia impregnated resin (i.e. ceramic coating) was applied to the combustion surfaces. This also improved the starting times of the JP-8-fueled engine and ultimately allowed for a 34-second starting time. Finally, the steady-state data from both the nitromethane-methanol and JP-8-fueled micro engine were compared. The JP-8-fueled engine showed signs of increased engine friction while having higher indicated fuel conversion efficiency and a higher overall system efficiency. The minimal ability of JP-8 to cool the engine via evaporative effects, however, created the necessity of increased cooling air flow. The conclusion reached was that JP-8-fueled micro engines could be viable in application, but not without additional research being conducted on combustion phenomenon and cooling requirements.

It is remarkable that there are no deployed military hybrid vehicles since battlefield fuel is approximately 100 times the cost of civilian fuel. In the commercial marketplace, where fuel prices are much lower, electric hybrid vehicles have become increasingly common due to their increased fuel efficiency and the associated operating cost benefit. An absence of military hybrid vehicles is not due to a lack of investment in research and development, but rather because applying hybrid vehicle architectures to a military application has unique challenges. These challenges include inconsistent duty cycles for propulsion requirements and the absence of methods to look at vehicle energy in a holistic sense. This dissertation provides a remedy to these challenges by presenting a method to quantify the benefits of a military hybrid vehicle by regarding that vehicle as a microgrid. This innovative concept allowed for the creation of an expandable multiple input numerical optimization method that was implemented for both real-time control and system design optimization. An example of each of these implementations was presented. Optimization in the loop using this new method was compared to a traditional closed loop control system and proved to be more fuel efficient. System design optimization using this method successfully illustrated battery size optimization by iterating through various electric duty cycles. By utilizing this new multiple input numerical optimization method, a holistic view of duty cycle synthesis, vehicle energy use, and vehicle design optimization can be achieved.

The aim of this special issue is to widen the existing debates on security privatization by looking at how and why an increasing number of private actors beyond private military and/or security companies (PMSCs) have come to perform various security related functions. While PMSCs produce security for profit, most other private sector actors make profit by selling goods and services that were originally not connected with security in the traditional understanding of the term. However, due to the continuous introduction of new legal and technical regulations by public authorities, many non- security related private businesses nowadays have to perform at least some security functions. Little research, however, has been done thus far, both in terms of security practices of non- security related private businesses and their impact on security governance. This introduction explains how this special issue contributes to closing this glaring gap by 1) extending the conceptual and theoretical arguments in the existing body of literature; and 2) offering a range of original case studies on the specific roles of non- security related private companies of all sizes, areas of businesses, and geographic origin.

Minimal research has explored what comprises a quality physical activity (PA) participation experience, particularly among military Veterans with a physical disability for whom evidence of the benefits of PA is growing. To address this research gap, this dissertation examines quality PA participation among military Veterans with a physical disability. Manuscript 1 explores the views of Veterans with a physical disability regarding what elements constitute a quality PA experience, and how these elements may be fostered. Eighteen Veterans with various physical disabilities and PA experiences participated in interviews. Four quality elements were identified via thematic analysis: group cohesion, challenge, having a role, and independence and choice. A further three factors (the physical and social environments, and program structure) were identified as precursors for a quality experience. Manuscript 2 explores how PA programs for Veterans with a physical disability are delivered, and how these delivery strategies link conceptually to quality participation. Interviews were conducted with program staff from three PA programs for Veterans, and program documentation collected, to develop an understanding of program delivery strategies. Four strategies with potential links to quality participation were identified through thematic analysis: foster social connections, challenge participants, tailor programs and outcomes to match participant needs, and include knowledgeable coaches and instructors. Manuscript 3 evaluates the participation of Veterans with functional impairments in PA events, and examines the relationships among quality precursors, quality elements, and participation outcomes. Results indicate that program participation did not promote long-term increases in PA indicators. However, an indicator of the quality element belongingness mediated the relationship at particular time-points between coach interpersonal skills and three participation outcomes: family integration, PA intentions, and PA planning. These findings suggest that a quality participation experience created by coaches may positively impact the transition to civilian life, and promote efforts to engage in ongoing PA. Overall, this dissertation contributes towards a greater depth in understanding of the experiences of Veterans with a physical disability in PA programs. The findings begin to provide a foundation for researchers and practitioners aiming to create, deliver, and promote quality PA interventions and programming for Veterans with a physical disability.
