Leading the Way?: Maine's Initial Experience in Expanding Coverage Through Dirigo Health Reforms

Examines interim indicators -- enrollment of the previously uninsured, responses from small firms and the working poor, and the impact on costs -- of Maine's progress in providing affordable health insurance through the Dirigo Health program

Charitable Immunity: The Plague of Modern Tort Concepts

It is the purpose of this paper to analyze the grounds upon which charitable institutions have been granted immunity from tort liability, to consider changing conditions and concepts affecting immunity, and finally, to discuss the extent to which the immunity exception should be abandoned

Improving cough and cold OTC medication use for children in Hardin County

Background: Ohio struggles with high infant mortality rates. This project was designed to combat incorrect use of cough and cold over-the-counter (OTC) medications. Parents or caregivers, especially those with low health literacy, often use these medications incorrectly in infants, sometimes leading to a fatal outcome. Methods: Utilizing a three-pronged approach, this IRB-approved project addresses the issue of incorrect cough and cold OTC medications use for infants in Hardin County. Passive education was provided to community members via social media/flyers, educational interventions were performed with community members (virtual or in-person), and continuing professional development (CPD) was provided to pharmacists and pharmacy technicians in Hardin County. Results: Passive education was disseminated in Hardin County. Thirty-eight community members attended the educational interventions; comparison of pre- and post-tests found statistically significant increases in knowledge (p=0.028). All participants indicated the information received was helpful, and 53% indicated they would change how cough and cold medications were administered. Thirteen professionals completed CPD; average post-test score=93%. Conclusion: It is important to teach parents and caregivers about proper use of cough and cold OTC medications. Education classes were effective in increasing community members’ knowledge, and CPD for pharmacy professionals reinforced opportunities for patient counseling

Fundamental Limits of Classical and Quantum Imaging

Quantum imaging promises increased imaging performance over classical protocols. However, there are a number of aspects of quantum imaging that are not well understood. In particular, it has so far been unknown how to compare classical and quantum imaging procedures. Here, we consider classical and quantum imaging in a single theoretical framework and present general fundamental limits on the resolution and the deposition rate for classical and quantum imaging. The resolution can be estimated from the image itself. We present a utility function that allows us to compare imaging protocols in a wide range of applications.Comment: 4 pages, 3 figures; accepted for Physical Review Letters, with updated title and fixed typo

Universal Robotic Gripper based on the Jamming of Granular Material

Gripping and holding of objects are key tasks for robotic manipulators. The development of universal grippers able to pick up unfamiliar objects of widely varying shape and surface properties remains, however, challenging. Most current designs are based on the multi-fingered hand, but this approach introduces hardware and software complexities. These include large numbers of controllable joints, the need for force sensing if objects are to be handled securely without crushing them, and the computational overhead to decide how much stress each finger should apply and where. Here we demonstrate a completely different approach to a universal gripper. Individual fingers are replaced by a single mass of granular material that, when pressed onto a target object, flows around it and conforms to its shape. Upon application of a vacuum the granular material contracts and hardens quickly to pinch and hold the object without requiring sensory feedback. We find that volume changes of less than 0.5% suffice to grip objects reliably and hold them with forces exceeding many times their weight. We show that the operating principle is the ability of granular materials to transition between an unjammed, deformable state and a jammed state with solid-like rigidity. We delineate three separate mechanisms, friction, suction and interlocking, that contribute to the gripping force. Using a simple model we relate each of them to the mechanical strength of the jammed state. This opens up new possibilities for the design of simple, yet highly adaptive systems that excel at fast gripping of complex objects.Comment: 10 pages, 7 figure

Temporality, vulnerability, and energy justice in household low carbon innovations

Decarbonisation and innovation will change the affordability of different domestic energy services. This has the potential to alleviate vulnerability to fuel poverty, but it could create new injustices unless the risks are preempted and actively mitigated. In this paper, we ask: In what ways can emerging low-carbon innovations at the household scale complement, and complicate, achieving energy justice objectives? Drawing from four empirical case studies in the United Kingdom, the paper highlights different risks that come from different types of innovation required to tackle different decarbonisation challenges. More specifically, it assesses four particular household innovations—energy service contracts, electric vehicles, solar photovoltaic (PV) panels, and low carbon heating—selected for their fit with a typology of incremental vs. radical technology and modest vs. substantial changes in user practices. It shows how in each case, such innovations come with a collection of opportunities but also threats. In doing so, the paper seeks to unveil the “political economy” of low-carbon innovations, identifying particular tensions alongside who wins and who loses, as well as the scope and temporality of those consequences

Observation of Macroscopic Structural Fluctuations in bcc Solid 4He

We report neutron diffraction studies of low density bcc and hcp solid 4He. In the bcc phase, we observed a continuous dynamical behaviour involving macroscopic structural changes of the solid. The dynamical behaviour takes place in a cell full of solid, and therefore represents a solidsolid transformation. The structural changes are consistent with a gradual rotation of macroscopic grains separated by low angle grain boundaries. We suggest that these changes are triggered by random momentary vibrations of the experimental system. An analysis of Laue diffraction patterns indicates that in some cases these structural changes, once initiated by a momentary impulse, seem to proceed at a constant rate over times approaching an hour. The energy associated with these macroscopic changes appears to be on the order of kT. Under similar conditions (temperature and pressure), these effects were absent in the hcp phase.Comment: 14 pages, 6 figure, accepted for PR
