Medical Countermeasures for Radiation Induced Health Effects: Reports of an Interagency Panel Session Held at the NASA Human Research Program Investigator's Workshop, January 26, 2017

An Interagency Panel Session organized by the NASA Human Research Program Space Radiation Program Element (SRPE) was held during the NASA Human Research Program (HRP) Investigators Workshop (IWS) in Galveston, Texas on January 26, 2017 to identify complementary research areas that will advance the testing and development of medical countermeasures (MCM) in support of radioprotection and radiation mitigation on the ground and in space. There were several areas of common interest identified among the various participating agencies. This report provides a summary of the topics discussed by each agency along with potential areas of intersection for mutual collaboration opportunities. Common goals included repurposing of pharmaceuticals, neutraceuticals for use as radioprotectors and/or mitigators, low-dose/chronic exposure paradigms, late effects post-radiation exposure, mixed-field exposures of gamma-neutron, performance decrements, and methods to determine individual exposure levels

Perception is Everything: Repairing the Image of American Drone Warfare

This thesis will trace the United States’ development of unmanned warfare from its initial use in the World Wars through the Cold War to its final maturation in the War on Terror. The examination will provide a summary of unmanned warfare’s history, its gradual adoption, and concerns regarding the proliferation of drones use to understand the emphasis on unmanned weapons in the American Military. In each phase of development, a single program will be focused on to highlight special areas of interest in the modern day. Finally, the modern era of unmanned systems will focus on the growing integration of new weapon systems which no longer fulfill niche roles in the armory but act as fully vetted frontline combatants. Brought together, this examination will show drones have earned their place as integral tools in the American military inventory as faithful defenders of democracy

Admission of Deaf Soldiers to the Military: Rethinking the Undifferentiated Soldier Paradigm

Keith Nolan, a deaf man with undergraduate and graduate degrees, asked to be admitted to military training to become a uniformed American soldier. The military said no, and the issue was joined. Nolan’s application presents the Department of Defense (DOD) with an opportunity to reconsider its historical bar to people who are deaf. The Article suggests a new paradigm in thinking about the selection criteria used to screen out deaf applicants for military service, a paradigm rooted in a disability studies framework. With a few exceptions in the Civil War, the United States armed forces have barred people with disabilities, including those who are deaf, from serving in the military. The current recruitment model is based on the “undifferentiated soldier,” which requires an applicant for military service to become combat-ready, that is, someone who can serve on the front line of fighting even if ultimately the soldier never enters the theater of war in his or her military career. As Keith Nolan’s case demonstrates, the military assumes deaf applicants are incapable of military service because they cannot become combat ready. These assumptions underline a DOD report to Congress last year that militates against deaf soldiers in the United States armed forces. It is time to rethink these assumptions

Software Architecture: Managing Design for Achieving Warfighter Capability

Proceedings Paper (for Acquisition Research Program)Software engineers will typically spend 50% or more of the total software development time designing software architecture, and that architecture may provide up to 80% of a modern weapon system''s functionality. Increasingly, these systems will operate within a network or other system-of-systems architecture. Obviously, the requirements driving that architectural design effort and the process for tracing requirement to functions, insight into the process, and control of the effort are critical for the successful development of the capability needed by the warfighter.Naval Postgraduate School Acquisition Research ProgramApproved for public release; distribution is unlimited

Horizontal Integration of Warfighter Intelligence Data: A Shared Semantic Resource for the Intelligence Community

We describe a strategy that is being used for the horizontal integration of warfighter intelligence data within the framework of the US Army’s Distributed Common Ground System Standard Cloud (DSC) initiative. The strategy rests on the development of a set of ontologies that are being incrementally applied to bring about what we call the ‘semantic enhancement’ of data models used within each intelligence discipline. We show how the strategy can help to overcome familiar tendencies to stovepiping of intelligence data, and describe how it can be applied in an agile fashion to new data resources in ways that address immediate needs of intelligence analysts

Impact of Increased Load Carriage Magnitude on the Dynamic Postural Stability of Men and Women

The impact of load carriage on dynamic postural stability affects the survivability of the Warfighter by influencing performance capabilities and injury incidence. Further, sex may interact with the relationship between load carriage and dynamic postural stability to further compromise survivability. PURPOSE: To investigate the effect of load carriage magnitude on dynamic postural stability of men and women and its relationship to jumping ability. METHODS: 32 subjects (16 men, 16 women) were investigated for maximum jump height and dynamic postural stability. Dynamic postural stability was assessed by subjects jumping a horizontal distance of 40% their height over a 30cm hurdle, landing on one leg on a force plate (sample rate = 1200 Hz). 3 trials were completed for 3 load conditions: +0, +20 and +30% body weight (BW). Dynamic postural stability was determined from ground reaction force data during landings, by calculation of the dynamic postural stability index (DPSI). Maximum jump height was assessed by subjects performing 3 countermovement jumps (sample rate = 1000 Hz). Two-way repeated measures ANOVA were used to compare mean DPSI scores between sexes and conditions (α = 0.05). Pearson’s Correlation Coefficients were used to determine the relationship between jump height and change in DPSI scores between conditions (α = 0.05). RESULTS: Load condition significantly affected DPSI (F = 100.304, p = 0.001). DPSI scores increased between the 0% (0.359 ± 0.041), 20% (0.396 ± 0.034) and 30% (0.420 ± 0.028) BW load conditions. No significant effect of sex on DPSI was found (F = 0.131). No significant sex by load interaction on DPSI was found (F = 0.393). No significant correlations were found between jump height and change in DPSI scores between conditions. CONCLUSION: Increased load was found to negatively affect dynamic postural stability, most likely as a result of modifying the demands of the task. Therefore, the dynamic postural stability of men and women changes comparably in response to increased load carriage magnitude. Future research should focus on the effects of load on dynamic postural stability under higher loads and during more military-specific tasks

Development vs. Deployment: How Mature Should a Technology be Before it is Considered for Inclusion in an Acquisition Program?

Proceedings Paper (for Acquisition Research Program)Modern military systems increasingly rely on the integration of multiple advanced technologies. While these technologies vastly increase warfighter capabilities, they also introduce risk into the system design and development process that tends to increase both its cost and duration. As acquisition cycle-times increase, warfighters must make do with dated technology for longer periods. Thus, there is an incentive to push as many advanced technologies as possible into each program to maximize warfighter capability over the next acquisition cycle. Unfortunately, the more new technologies a system has, the more risky its acquisition becomes, and consequently, its duration and cost increase even further. Thus, there is a feedback effect that exacerbates the problem. Open-architecture designs can partially alleviate this problem, but some technology decisions are so integral to a system''s design that they cannot be relegated to future upgrades. Consequently, there is a tradeoff between incorporating these technologies now and increasing program risk or developing and evaluating them further but potentially postponing their application to future acquisition cycles. Our paper will examine this tradeoff by considering a new technology''s contribution to program risk.Approved for public release; distribution is unlimited.Naval Postgraduate School Acquisition Research Progra

Cost and Risk Considerations for Test and Evaluation of Unmanned and Autonomous Systems of Systems

The evolutionary nature of Unmanned and Autonomous systems of systems (UASoS) acquisition needs to be matched by evolutionary test capabilities yet to be developed. As part of this effort we attempt to understand the cost and risk considerations for UASoS Test and Evaluation (T&E) and propose the development of a parametric cost model to conduct trade-off analyses. This paper focuses on understanding the need for effort estimation for UASoS, the limitations of existing cost estimation models, and how our effort can be merged with the cost estimation processes. We present the prioritization of both technical and organizational cost drivers. We note that all drivers associated with time constraints, integration, complexity, understanding of architecture and requirements are rated highly, while those regarding stakeholders and team cohesion are rated as medium. We intend for our cost model approach to provide management guidance to the T&E community in estimating the effort required for UASoS T&E

Metrics Pilot Project for Military Avionics Sustainment: Experimental Design and Implementation Plan

This working paper outlines the design of an experiment, employing a pilot project, for identifying and validating new metrics for managing the US Air Force military avionics sustainment system. The paper also presents a plan for implementing the pilot project. The experimental design allows for the quantitifation of the effects of the new metrics, while controlling for the effects of other factors impacting the observed outcomes. Underlying the pilot project, and the proposed experimental design, are three main hypotheses derived from earlier research: (a) currently used metrics foster local optimization rather than system-wide optimization; (b) they do not allow measures of progress towards the achievement of system-wide goals and objectives, and, hence, do not allow visibility into the impact of depot maintenance on the warfighter; and (c) they are driving the “wrong behavior,” causing suboptimal decisions governing maintenance and repair priorities and practices and, as a result, undermining the efficiency and effectiveness of the sustainment system, despite the fact that the Air Force sustainment system has a dedicated and highly skilled workforce supporting the warfighter
