Checklist usage can increase performance in complex, high-risk domains. While paper checklists are valuable, they are static, slow to access, and show both too much and too little information. We introduce <i>Dynamic Procedure Aids</i> to address four key problems in checklist usage: ready access to aids, rapid assimilation of content, professional… (More)
Insect endosymbionts influence many important metabolic and developmental processes of their host. It has been speculated that they may also help to manipulate and suppress plant defenses to the benefit of herbivores. Recently, endosymbionts of the root herbivore Diabrotica virgifera virgifera have been reported to suppress the induction of defensive… (More)
Emergency medical teams collaborate to solve problems and take care of patients under time pressure and high cognitive load, in noisy and complex environments. This paper presents preliminary work in the design and evaluation of head-mounted and multi-surface displays in supporting teams with interactive checklists and more generally dynamic cognitive aids.
Sucrose transporters (SUTs) translocate sucrose (Suc) across cellular membranes, and in eudicots, multiple SUTs are known to function in Suc phloem loading in leaves. In maize (Zea mays), the Sucrose Transporter1 (ZmSut1) gene has been implicated in Suc phloem loading based upon RNA expression in leaves, electrophysiological experiments, and phenotypic… (More)
Positional cloning in maize (Zea mays) requires development of markers in the region of interest. We found that primers designed to amplify annotated insertion-deletion polymorphisms of seven base pairs or greater between B73 and Mo17 produce polymorphic markers at a 97% frequency with 49% of the products showing co-dominant fragment length polymorphisms.… (More)
Complex, perilous domains like surgery and aviation require accurate responses under extreme time constraints. Checklists improve important outcomes in these domains. However, current designs are based largely on intuition; there is little theory or empirical work about designing effective procedure aids. Furthermore, discretionary checklist use is… (More)
In pines, self-pollination rates can be as high as 34% yet only 5% of viable seed is a product of self-fertilization. This decline in selfed seed viability is the consequence of post-fertilization exclusion mechanisms operating via the embryo lethal system. Recent molecular marker dissection studies suggest that the embryo lethal system is composed of… (More)
Cognitive aids such as checklists have been shown to benefit medical teams working in routine and crisis environments. This video presents a team of physicians reacting to a simulated operating room emergency, demonstrating potential benefits of interactive cognitive aids in medicine.
During daylight, plants produce excess photosynthates, including sucrose, which is temporarily stored in the vacuole. At night, plants remobilize sucrose to sustain metabolism and growth. Based on homology to other sucrose transporter (SUT) proteins, we hypothesized the maize (Zea mays) SUCROSE TRANSPORTER2 (ZmSUT2) protein functions as a sucrose/H+… (More)
