Pilot weather advisor

The results of the work performed by ViGYAN, Inc., to demonstrate the Pilot Weather Advisor cockpit weather data system using a broadcast satellite communication system are presented. The Pilot Weather Advisor demonstrated that the technical problems involved with transmitting significant amount of weather data to an aircraft in-flight or on-the-ground via satellite are solvable with today's technology. The Pilot Weather Advisor appears to be a viable solution for providing accurate and timely weather information for general aviation aircraft

Protecting Research: Copyright, Common-Law Alternatives, and Federal Preemption

Under federal copyright law, an author\u27s expression is protected but his ideas and discoveries are not. Professor Shipley explores the possibility of expanding copyright to protect the research of nonfiction authors, but concludes that such an expansion would undermine federal copyright policy. State-law remedies exist that will provide such protection if they are not preempted by federal law. Professor Shipley concludes that most contract claims and some misappropriation claims will survive preemption and therefore are a means by which nonfiction authors can protect their research

Clinician and patients’ views about self-management support in arthritis: a cross-sectional UK survey

Objective The overall aims of the study are to (a) establish receipt and provision of self-management support for patients with inflammatory arthritis in the UK; and (b) establish if receipt of selfmanagement support is associated with patient’s knowledge, skills and confidence to selfmanage. Methods Questionnaire for patients and healthcare professionals were sent to members and associates of the National Rheumatoid Arthritis Society (NRAS). Patients completed the Patient Activation Measure (PAM), and questions about receipt of self-management support. Healthcare professionals completed the Clinician Support PAM and questions about provision of self-management support. Results A total of 886 patients and 117 healthcare professionals completed a questionnaire. Only 15% of patients had attended a structured self-management programme. Over half of patients reported having the skills, confidence and knowledge to self-manage and this was associated with receipt of self-management support embedded in routine care. All healthcare professionals felt that patients should be actively involved in their own care, however, 60% were unable to offer structured self-management support. Healthcare professionals reported engaging in more embedded self-management support than patients reported receiving in routine care

Perspectives on optimizing local delivery of drugs to peripheral nerves using mathematical models

Drug therapies for treating peripheral nerve injury repair have shown significant promise in preclinical studies. Despite this, drug treatments are not used routinely clinically to treat patients with peripheral nerve injuries. Drugs delivered systemically are often associated with adverse effects to other tissues and organs; it remains challenging to predict the effective concentration needed at an injured nerve and the appropriate delivery strategy. Local drug delivery approaches are being developed to mitigate this, for example via injections or biomaterial-mediated release. We propose the integration of mathematical modeling into the development of local drug delivery protocols for peripheral nerve injury repair. Mathematical models have the potential to inform understanding of the different transport mechanisms at play, as well as quantitative predictions around the efficacy of individual local delivery protocols. We discuss existing approaches in the literature, including drawing from other research fields, and present a process for taking forward an integrated mathematical-experimental approach to accelerate local drug delivery approaches for peripheral nerve injury repair.

Reorienting with terrain slope and landmarks

Orientation (or reorientation) is the first step in navigation, because establishing a spatial frame of reference is essential for a sense of location and heading direction. Recent research on nonhuman animals has revealed that the vertical component of an environment provides an important source of spatial information, in both terrestrial and aquatic settings. Nonetheless, humans show large individual and sex differences in the ability to use terrain slope for reorientation. To understand why some participants—mainly women—exhibit a difficulty with slope, we tested reorientation in a richer environment than had been used previously, including both a tilted floor and a set of distinct objects that could be used as landmarks. This environment allowed for the use of two different strategies for solving the task, one based on directional cues (slope gradient) and one based on positional cues (landmarks). Overall, rather than using both cues, participants tended to focus on just one. Although men and women did not differ significantly in their encoding of or reliance on the two strategies, men showed greater confidence in solving the reorientation task. These facts suggest that one possible cause of the female difficulty with slope might be a generally lower spatial confidence during reorientation
