- We sought to determine if sickness behaviors (decreased social interaction and pain) are induced in a rat model of work-related overuse and effectiveness of anti-inflammatory treatments. Rats first trained to learn a high force reaching task (15 min/week day for 6 wks), with subsets treated prophylactically with ibuprofen or anti-TNFalpha. Others performed a high repetition high force (HRHF) task for 6 or 12 weeks (2 hrs/day, 3 days/wk) untreated, or with ibuprofen, anti-TNFalpha or rest treatments beginning task week 5. Untreated HRHF rats had increased IL-1beta, IL-6 and TNFalpha in serum and brain, increased Substance P in spinal cord, decreased social interaction and increased forepaw allodynia. Secondary antiinflammatory treatments attenuated social interaction and brain changes, but not allodynia or spinal cord changes; rest provided partial attenuation. Prophylactic treatments prevented all changes. Thus, inflammatory mechanisms mediate the development of sickness behaviors induced by work-related overuse, but not maintenance of allodynia.

- In modern military organizations teamwork performance is central, yet the underlying factors contributing to such performance are debated. The purpose of this paper was to investigate how several known teamwork measures relate to a prior model of operator performance (Nählinder et al, 2004). This study expands this model to the team level and in the command and control domain. Specifically, this paper studies the relationship between individual and team workload measures, situation awareness measures, and performance measures in 18 two-person teams. The study has two major findings: Firstly, the various team cognition measures statistically cluster into four meaningful concepts (workload, teamwork, situation awareness and performance). Secondly, a Structural Equation Model indicates that the relationship between the various individual and team measures can be described in a model resembling the model found in previous studies (Nählinder et al, 2004). In particular, the results show that the general workload in the microworld study has a negative effect on both teamwork and situation awareness. Teamwork, in turn, also affects situation awareness, which has major impact on performance.

"Safety is everywhere" : The Constituents of Maritime Safety

- Although maritime safety is one of the key terms in regulation, guidelines and recommendations, such as SOLAS (International Convention for the safety of life at sea (IMO, 1974), in the shipping domain, there is, to the best of our knowledge, neither an explanation of this specific type of safety nor any explicit understanding on how it is promoted by those who work on board of merchant vessel. This qualitative study approaches maritime safety from a crew perspective and discusses what constituents should be considered to be part of maritime safety.

Spatial Judgments from Different Vantage Points: A Different Perspective

- Todorovic (2008) reported that there are systematic errors in the perception of 3-D space when viewing 2-D linear perspective drawings depending on the observer’s vantage point. Because Todorovic’s findings were restricted to the horizontal plane, the current study was designed to determine whether the magnitude of these errors would be similar in the vertical plane. Participants viewed a 2D image containing rows of columns aligned on parallel converging lines receding to a vanishing point. They were asked to judge where in the physical room the next column should be placed. The results support Todorovic (2008) in that systematic deviations in the spatial judgments depended on vantage point for both the horizontal and vertical planes. However, the pattern of deviation differed between the two planes. While judgments in both planes failed to compensate adequately for the vantage point shift, the vertical plane induced greater distortions of the stimulus image itself within each vantage point.

- The purpose of this study was to gain a better understanding of driver's perceptions of Head-Up Displays (HUD). Many HUD studies have been conducted but few have allowed drivers to test a HUD in their own vehicle, allowing them to choose the best HUD location for themselves. Forty participants drove their own vehicles using a portable HUD device, testing different HUD locations, and then rated the HUD using the Technology Acceptance Model. The results showed that the HUD was rated as easy to use and the drivers intended to use it in continuation. The drivers wanted the HUD to be located outside of the traffic scene, below their line of sight. These results give support for new HUD locations and for increased HUD implementation.
