    National research, development, test, and evaluation ground testing capabilities in the United States are at risk. There is a lack of vision and consensus on what is and will be needed, contributing to a significant threat that ground test capabilities may not be able to meet the national security and industrial needs of the future. To support future decisions, the AIAA Ground Testing Technical Committees (GTTC) Future of Ground Test (FoGT) Working Group selected and reviewed 20 seminal documents related to the application and direction of ground testing. Each document was reviewed, with the content main points collected and organized into sections in the form of a gap analysis current state, future state, major challenges/gaps, and recommendations. This paper includes key findings and selected commentary by an editing team

    This project was conducted with the help and encouragement of British Airways (BA) management. It was carried out at Heathrow Airport, Terminal 5 (T5) where a new Resource Management System (RMS) that is based upon Internet Protocol (IP) has been implemented. RMS has replaced traditional pen and paper and radio systems for allocating work tasks to 4,000 airport operational staff. This research project studied one application of the RMS system; the allocation of tasks to the coach drivers in the Ground Transport Services (GTS) department. The user acceptance of the RMS system by the drivers was evaluated. In the previous 20 years, user acceptance theories have been developed which have shown that increased user acceptance of new Information Technology (IT) projects significantly reduces costs and improves efficiency (Davis, 1980). The most comprehensive theory is that of Sun and Zhang (2006) who identify critical factors regarding individual user acceptance (gender, age, experience, cultural background and intellectual capability). This research project used a case study methodology: three days were spent airside at T5 observing and interviewing a sample of drivers. The project research question was: 'Can the degree of RMS acceptance by the GTS end-users be determined by factors identified in user acceptance theories?' Essentially, it was not possible to answer this question because of two reasons. First there was little difference in level of user acceptance; it was very high for all users. Second there was also very little difference in the sample and population. The drivers were all male, over 90% between 42 and 65 years of age, with similar levels of experience regarding the RMS technology and computers in general. In addition, it was not possible to measure any difference between the intellectual capabilities of the participants. A difference in the cultural background was identified; there were two ethnic groups, Asian and Caucasian. However, detailed analysis of the responses to the questionnaire demonstrated that there was no evidence of different levels of user acceptance of these groups. Recommendations to improve the testing of user acceptance theories are included in this report

    The Correlation of Human Capital on Costs of Air Force Acquisition Programs

    Previous studies have linked human capital with performance. The studies have shown performance, measured as output, of a firm can be increased by adding more personnel and/or increasing education levels. This research uses the Cobb-Douglas Production function to build upon that relationship of inputs to outputs. The output in this study is the average cost overrun of Aeronautical Systems Center research, development, test, and evaluation contracts managed from 1994 to 2008. The inputs are the numbers of military/government employee financial managers, program managers, engineers, rated personnel, and military/government employees in those career fields possessing a graduate degree or higher. A time series regression was conducted using those inputs to outputs while controlling for other factors such as budgetary fluctuations, inflation, and individuals doing defense related work in the private sector as a proxy for contractors working in program offices. The results indicate a negatively correlated relationship exists between human capital and cost overruns

    DEPARTMENT OF DEFENSE JOINT AIRCREW SURVIVAL FLIGHT VEST

    The purpose of this research is to analyze the feasibility of a joint aircrew survival flight vest program to satisfy the performance requirements across the military Services. The Department of Defense (DOD) has multiple type, model, and series aircraft in its inventory to meet the capabilities validated by the Joint Requirements Oversight Council. Each aircraft comes with a variety of Aviation Life Support Systems such as the aircrew survival flight vest. There are a variety of aircrew survival flight vests across the DOD performing similar functions, such as ballistic protection, signaling and communications, and providing flotation in a maritime environment. In recent years, Defense Acquisitions programs have been becoming more joint by increasing commonality to cut costs by reducing redundant programs among the different services. Currently, the various aircrew flight vests that are being used remain under the control of several program executive offices. This research examined the feasibility of a joint aircrew survival flight vest by using a combination of the case study method and the cost-effectiveness analysis. We conclude that a joint aircrew survival flight vest with a modular design would be the most effective option. The services will have the flexibility to tailor the joint vest with modules to meet performance specifications.Outstanding ThesisMajor, United States Marine CorpsCaptain, United States Marine CorpsEnsign, United States NavyApproved for public release.

    The impact of an intervention to introduce malaria rapid diagnostic tests on fever case management in a high transmission setting in Uganda: A mixed-methods cluster-randomized trial (PRIME).

    Rapid diagnostic tests for malaria (mRDTs) have been scaled-up widely across Africa. The PRIME study evaluated an intervention aiming to improve fever case management using mRDTs at public health centers in Uganda. A cluster-randomized trial was conducted from 2010-13 in Tororo, a high malaria transmission setting. Twenty public health centers were randomized in a 1:1 ratio to intervention or control. The intervention included training in health center management, fever case management with mRDTs, and patient-centered services; plus provision of mRDTs and artemether-lumefantrine (AL) when stocks ran low. Three rounds of Interviews were conducted with caregivers of children under five years of age as they exited health centers (N = 1400); reference mRDTs were done in children with fever (N = 1336). Health worker perspectives on mRDTs were elicited through semi-structured questionnaires (N = 49) and in-depth interviews (N = 10). The primary outcome was inappropriate treatment of malaria, defined as the proportion of febrile children who were not treated according to guidelines based on the reference mRDT. There was no difference in inappropriate treatment of malaria between the intervention and control arms (24.0% versus 29.7%, adjusted risk ratio 0.81 95\% CI: 0.56, 1.17 p = 0.24). Most children (76.0\%) tested positive by reference mRDT, but many were not prescribed AL (22.5\% intervention versus 25.9\% control, p = 0.53). Inappropriate treatment of children testing negative by reference mRDT with AL was also common (31.3\% invention vs 42.4\% control, p = 0.29). Health workers appreciated mRDTs but felt that integrating testing into practice was challenging given constraints on time and infrastructure. The PRIME intervention did not have the desired impact on inappropriate treatment of malaria for children under five. In this high transmission setting, use of mRDTs did not lead to the reductions in antimalarial prescribing seen elsewhere. Broader investment in health systems, including infrastructure and staffing, will be required to improve fever case management

    The Use Of Pc Based Simulation Systems In The Training Of Army Infantry Officers - An Evaluation Of The Rapid Decision Trainer

    Get PDF
    This research considers two modes of training Army infantry officers in initial training to conduct a platoon live fire exercise. Leaders from groups that were training with the current classroom training methods were compared to leaders from groups whose training was augmented with a PC based training system known as the Rapid Decision Trainer (RDT). The RDT was developed by the US Army Research Development and Engineering Command for the purpose of aiding in the training of tactical decision making and troop leading procedures of officers in the initial levels of training to become rifle platoon leaders. The RDT allows the leader in training to run through platoon level operations prior to live execution in a simulated combat environment. The focus of the system is on leadership tasks and decision making in areas such as unit movement, internal unit communication and contingency planning, and other dismounted infantry operations. Over the past year, some Infantry Officer Basic Course platoons at Ft. Benning have used the RDT in an experimental manner. Anecdotal evidence suggests that the system is beneficial in training IOBC officers. The Army Research Institute (ARI) conducted a preliminary evaluation of the RDT in March 2005 (Beal 2005). However, no quantitative measures were used in the evaluation of the RDT, only subjective evaluations of the users. Additionally, there were no formal evaluations by the training cadre, only the users themselves. This experiment continues the work of ARI and uses qualitative and quantitative data from both users and the evaluating cadre. In this experiment, the effectiveness of the RDT was evaluated through measuring leader behaviors and personal preferences. Three measurement approaches were used; (1) quantitative performance measures of leader actions, (2) qualitative situational awareness and evaluations of inclusion in the non leader players, and (3) a qualitative evaluation of the system\u27s usability and effectiveness by system users. Analysis reveals statistically significant findings that challenge the current norms
