Applications of Gaming Techniques to Coastal Zone Problems

The boundary between sea and land is an area which presents enormous management challenges. It is an area of fragile ecology, dense and growing population, multiple competing demands for resource use, a multitude of regulatory agencies, and far from complete scientific understanding. Given these difficulties, planning for coastal zone management frequently suffers from incomplete data, lack of consensus among users, and lack of support from government authorities. This paper proposes gaming as a tool for assisting in the information gathering, education, consensus building, and communications elements of planning. This is achieved by developing a planning game which is designed to consider coastal zone management issues arising from climate change. The game is designed specifically to be used for educational purposes from the perspective of state planners, but could be modified for educational or analytical play at the local, regional, or national level

Cell Phone-Induced Perceptual Impairments During Simulated Driving

Our research assessed the effects of cellular phone conversations on driving performance. When subjects were deeply involved in cellular phone conversations using either a hand-held or hands-free device, they were more than twice as likely to miss simulated traffic signals presented at the center of fixation than when they were not distracted by the cell phone conversation. By contrast, performance was not disrupted by listening to radio broadcasts or listening to a book on tape. One might argue that when subjects were conversing on a cell phone that they detected the simulated traffic signals, but that the responses to them were suppressed. To assess this, we examined the implicit perceptual memory for items that were presented at fixation but called for no response. Implicit perceptual memory was strong when subjects were not engaged in a cellphone conversation but impaired when they were so engaged. We suggest that active participation in a cell phone conversation disrupts performance by diverting attention to an engaging cognitive context other than the one immediately associated with driving

State Imperiled Species Legislation

State wildlife conservation programs are essential to accomplishing the national goal of extinction prevention. By virtue of their constitutional powers, their expertise, and their on-the-ground personnel, states could—in theory—accomplish far more than the federal agencies directly responsible for implementing the Endangered Species Act (ESA). States plausibly argue that they can catalyze collaborative conservation that brings together key stakeholders to improve conditions for imperiled species. Bills to revise the ESA seek to delegate greater authority to states. We evaluated states’ imperiled species legislation to determine their legal capacity to employ the key regulatory tools that prompt collaborative conservation. All but four states possess statutory programs to identify species on the brink of extinction. Most of them include both animals protected under the ESA and wildlife imperiled just within the boundaries of the state. Thirty-four states legislate imperiled plant protection programs. States generally fail to prohibit habitat impairment by private parties, lack permit programs to minimize incidental harms to species and spur habitat conservation, and do not restrict state agency actions that undermine species recovery. Compared to the key regulatory programs of the ESA that prompt stakeholders to collaborate on conservation, state laws—in general—reflect a more permissive attitude. Though state laws, in the aggregate, only weakly support cooperative federalism, some state legislative provisions are very strong. Illinois, Massachusetts, and Wisconsin even go beyond the ESA in their protective measures. Major funding increases to pay for conservation measures could overcome weak agency regulatory authority, but prospects for a spending spree are dim. Therefore, some state legislative reform will be necessary to implement stronger cooperative federalism under the ESA

The Evaluation of a Graphical Pulmonary Display in Anesthesiology

We have developed graphic technology to display data from the respiratory monitors used during anesthesia. The display uses color, texture, shape and emergent features to highlight abnormal pulmonary physiology. Nineteen anesthesiologists participated in a simulator based evaluation (METI, Sarasota, FL.). Half the subjects used the metaphor display and half did not. Each subject was trained for 10 minutes on the pulmonary display. The time difference during the obstructed endotracheal tube did prove significant (p=0.02) in favor of the pulmonary display condition. During the intrinsic PEEP scenario, the subjects treated the patient earlier (positive trend p=0.l) with the pulmonary display compared to the control condition. The group that used the pulmonary display treated a restricted upper airway more quickly (2.3 min vs. 3.9 min). Subjects liked the simplicity of the design. In future studies, we hope to further reduce the time for the detection and treatment of all scenarios by improving the design\u27s intuitiveness, integration, and emergent features

Method and apparatus for monitoring dynamic cardiovascular function using n-dimensional representatives of critical functions

A method, system, apparatus and device for the monitoring, diagnosis and evaluation of the state of a dynamic pulmonary system is disclosed. This method and system provides the processing means for receiving sensed and/or simulated data, converting such data into a displayable object format and displaying such objects in a manner such that the interrelationships between the respective variables can be correlated and identified by a user. This invention provides for the rapid cognitive grasp of the overall state of a pulmonary critical function with respect to a dynamic system

Evaluation of a Graphical Anesthesia Drug Display for Space Travel

As the frequency and duration of space travel increase, the potential need for emergency medical care in space grows, and with it the need for patient monitoring devices supporting therapeutic treatment. Providing emergency care to an injured astronaut may necessitate immediate surgery. During such events, the timely administration of anesthetic agents will need to be performed by someone who is not a formally trained anesthesiologist. The availability of usable real-time displays of intravenous anesthetic concentrations and effects could significantly enhance intraoperative clinical decision-making both in space and on earth. The effectiveness of the real-time anesthesia display on the management of total intravenous anesthesia was determined by 31 anesthesiologists participating in a simulation study. In the presence of the anesthesia drug display, clinicians maintained physiologic indicators such as blood pressure and heart rate closer to baseline levels. Participants also reported an increase in perceived performance when using the drug display. The results indicate that surgeries on earth and in orbit would benefit from the implementation of this display

Self-control or social control - what determines sleep hygiene in bed-sharing couples?

Objectives:: To investigate intimate partners’ impact on sleep hygiene with focus on the temporal dimension and differential predictors of sleep hygiene in co-sleepers and individual sleepers. Material and Methods:: Habitual co-sleepers and individual sleepers (n=102) completed a cross-sectional, self-report, in-lab, digital survey on sleep hygiene, habitual sleeping arrangement, self-control, depressiveness, and sociodemographic parameters. Results:: The relationship between sleeping arrangement and sleep hygiene in co-sleepers was time-dependent with an initial steep incline and a subsequent plateau at approximately one year of co-sleeping routine. Co-sleepers with more than one year of unaltered sleeping arrangement had significantly better sleep hygiene than co-sleepers with less than one-year or individual sleepers. More than one-year continuity of the sleeping arrangement moreover robustly predicted sleep hygiene in co-sleepers whereas self-control was the dominant predictor in individual sleepers. Conclusion:: Amongst others, our findings support the idea that insomnia treatment could be improved by becoming sensitive to the habitual sleeping arrangement

Pulmonary Metaphor Design and Anesthesia Simulation Testing

Medical decision making is a crucial process to successfully treat a critical medical emergency. During an unexpected medical event, astronauts, like anesthesiologists, must react quickly in a complex environment. Tools, such as the pulmonary metaphor display, were created to aid the medical caregiver\u27s decision making process. The pulmonary metaphor display is designed to help the caregiver collect and integrate pulmonary data to provide a more accurate, quicker diagnosis and treatment. The following outline anesthesiology simulation study will provide the data to prove that the pulmonary metaphor display is beneficial to medical decision making

Evaluating Medical Devices Remotely: Current Methods and Potential Innovations

Objective: We present examples of laboratory and remote studies, with a focus on studies appropriate for medical device design and evaluation. From this review and description of extant options for remote testing, we provide methods and tools to achieve research goals remotely. Background: The FDA mandates human factors evaluation of medical devices. Studies show similarities and differences in results collected in laboratories compared to data collected remotely in non-laboratory settings. Remote studies show promise, though many of these are behavioral studies related to cognitive or experimental psychology. Remote usability studies are rare but increasing, as technologies allow for synchronous and asynchronous data collection. Method: We reviewed methods of remote evaluation of medical devices, from testing labels and instruction to usability testing and simulated use. Each method was coded for the attributes (e.g., supported media) that need consideration in usability studies. Results: We present examples of how published usability studies of medical devices could be moved to remote data collection. We also present novel systems for creating such tests, such as the use of 3D printed or virtual prototypes. Finally, we advise on targeted participant recruitment. Conclusion: Remote testing will bring opportunities and challenges to the field of medical device testing. Current methods are adequate for most purposes, excepting the validation of Class III devices. Application: The tools we provide enable the remote evaluation of medical devices. Evaluations have specific research goals, and our framework of attributes helps to select or combine tools for valid testing of medical devices

Bed-Sharing in Couples Is Associated With Increased and Stabilized REM Sleep and Sleep-Stage Synchronization

Methods Young healthy heterosexual couples underwent sleep-lab-based polysomnography of two sleeping arrangements: individual sleep and co-sleep. Individual and dyadic sleep parameters (i.e., synchronization of sleep stages) were collected. The latter were assessed using cross-recurrence quantification analysis. Additionally, subjective sleep quality, relationship characteristics, and chronotype were monitored. Data were analyzed comparing co-sleep vs. individual sleep. Interaction effects of the sleeping arrangement with gender, chronotype, or relationship characteristics were moreover tested. Results As compared to sleeping individually, co-sleeping was associated with about 10% more REM sleep, less fragmented REM sleep (p = 0.008), longer undisturbed REM fragments (p = 0.0006), and more limb movements (p = 0.007). None of the other sleep stages was significantly altered. Social support interacted with sleeping arrangement in a way that individuals with suboptimal social support showed the biggest impact of the sleeping arrangement on REM sleep. Sleep architectures were more synchronized between partners during co-sleep (p = 0.005) even if wake phases were excluded (p = 0.022). Moreover, sleep architectures are significantly coupled across a lag of ± 5min. Depth of relationship represented an additional significant main effect regarding synchronization, reflecting a positive association between the two. Neither REM sleep nor synchronization was influenced by gender, chronotype, or other relationship characteristics. Conclusion Depending on the sleeping arrangement, couple's sleep architecture and synchronization show alterations that are modified by relationship characteristics. We discuss that these alterations could be part of a self-enhancing feedback loop of REM sleep and sociality and a mechanism through which sociality prevents mental illness
