| The Department of Defense (DOD) is required, by law, to maintain a core logistics capability that is government owned and government operated to meet contingency and other emergency requirements. Military depots play a key role in maintaining this core capability, although in recent years DOD has significantly increased its use of contractors. At the subcommittee's request, GAO examined the extent to which (1) DOD has accurately assessed whether it has ... |

| This thesis presents the results of research into the Boundary Avoidance Tracking (BAT) theory, which states that often pilots control an aircraft not in an attempt to maintain some condition, but to avoid some real or perceived boundaries. This pilot modeling concept was studied using over 30 pilots in simulator and flight tests. The pilot-aircraft system was evaluated with 3 different lateral-directional control models. Pilots were given a roll angle ... |

| Technology enabled non-face-to-face collaboration has the potential to enhance information sharing and shared situational awareness (SSA) by providing near real-time information to a wide audience. Collaborators require an awareness of what critical information should be shared to develop this SSA. Previous research suggested that participants, while reporting that they shared relevant information, in actuality did not. To explore this issue, the previous research was repeated with the addition of having ... |

|
| Heat acclimatization (HA) and personal body-cooling are effective methods of heat stress mitigation. HA involves conditioning the body to function under hot conditions by exposing the individual to an incremental level of heat stress daily over 10 to 14 days. Although HA improves thermoregulation during heat exposure, effective physical heat exchange between the body and environment must still take place. Operating with body armour may limit the benefits of HA ... |

| Soldiers will be required to perform missions using remote technology with increasing frequency as the U.S. Army transforms. Soldiers will be asked to carry out missions that will require them to be at greater standoff distance at the cost of degraded sensory information and resulting limited system performance. Historically, teleoperated systems have had capabilities that are twice the error rate and time required to perform a mission. This is due ... |

| Change blindness results from the absence of attention from the source of a change. Unsurprisingly, change blindness worsens in dual task and high workload conditions. Such is the environment in which teams of operators in military command and control missions operate, yet little is known about change blindness susceptibility in these conditions. A flicker task required individuals and dyads to detect changes under high and low task difficulty. Reaction time, ... |

| Distributed cognition (Hutchins, 1995a) is a theoretical framework that explains cognitive activities embodied and situated within the work setting and the artifacts used in the environment. Distributed cognition emphasizes the distributed nature of cognitive phenomena across individuals, tools/technologies, and internal/external representations. The unit of analysis goes beyond the cognitions of a single individual and focuses on the functional system as a whole. Distributed cognition examines the relation between individuals, the ... |

| The United States military relies on dental readiness as a key component of a service members' medical readiness status. Excellent oral health is a force multiplier because the dental emergency rate diminishes when the oral health status of the force increases. In recent years the Army's dental accessions have dropped to all time lows and there are an insufficient number of dentists in the Corp to handle the current workload. ... |

| In 2004, Congress passed the Intelligence Reform and Terrorism Prevention Act to reform security clearance processes. Much of GAO's experience in evaluating personnel security clearance processes over the decades has consisted of examining the Department of Defense's (DoD) program, which maintains about 2.5 million clearances on service members, DoD civilian employees, legislative branch employees, and industry personnel working for DoD and 23 other federal agencies.

| The goal of net-centric warfare (NCW) is to give soldiers an information advantage that leads to a war-fighting advantage. However, NCW systems are quite complex and dynamic, characteristics which can lead to impaired situation awareness (SA) and increased mental workload. It has been suggested that an automated alerting system would help Soldiers focus their attention on mission critical events. This series of experiments investigated how automated audio-visual alerts affect user ... |

| Visual search tasks are known to be cognitive capacity demanding and therefore may be improved by training in an augmented reality (AR) environment. During the experimental task, 64 participants searched for enemies (while cued from visual, auditory, tactile, combinations of two, or all three modality cues) and tried to shoot them while avoiding shooting the civilians (fratricide) for two 2-minute low-workload scenarios, and two 2-minute high-workload scenarios.

| Task-Centered Design (TCD) of human-systems interfaces focuses on supporting the user throughout all phases of tasks from initiation to completion. TCD typically requires software that monitors aspects of system information to trigger tasks, develop user-friendly information sets, propose task solutions and actions, and confirm actions as directed and approved by the operator. The operator monitors tasks awaiting completion on a Task Manager display. We demonstrate that moment-to-moment operator workload monitoring ... |
