Aliens and Equal Protection: Why Not the Right To Vote?

A constitutional right of at least some aliens to vote does not seem to me at all unthinkable. Throughout much of the nineteenth century and part of the twentieth, aliens enjoyed the right to vote in a great many states. The states that extended the franchise to aliens plainly did not believe that they were acting under constitutional compulsion. But given our present understanding of the mission of the equal protection clause, much can now be said in defense of such a constitutional right. My purpose here is to outline the case that might be made for the right of aliens to vote. I should make clear at the outset, however, that this is an area where one must proceed with caution, for the Supreme Court, despite its now numerous incursions into the thicket of politics and voting, has barely begun to construct a framework for analyzing questions concerning the nature of political representation and the definition of a political community. Indeed, the inscrutability of these questions and the sense of unease produced by discussion of them may account for the general reluctance to face squarely the issues raised by alien suffrage

Cost per case or total cost? The potential of prevention of hand injuries in young children – Retrospective and prospective studies

<p>Abstract</p> <p>Background</p> <p>Health-care costs for hand and forearm injuries in young children are poorly documented. We examined costs in 533 children injured years 1996–2003.</p> <p>Methods</p> <p>Health-care costs and costs for lost productivity were retrospectively calculated in children from three catchment areas in Sweden. Seven case categories corresponding to alternative prevention strategies were constructed.</p> <p>Results</p> <p>Over time, diminishing number of ward days reduced the health-care cost per case. Among children, the cost of lost productivity due to parental leave was 14 percent of total cost. Fingertip injuries had low median costs but high total costs due to their frequency. Complex injuries by machine or rifle had high costs per case, and despite a low number of cases, total cost was high. Type of injury, surgery and physiotherapy sessions were associated with variations in health-care cost. Low age and ethnic background had a significant effect on number of ward days.</p> <p>Conclusion</p> <p>The costs per hand injury for children were lower compared to adults due to both lower health-care costs and to the fact that parents had comparatively short periods of absence from work. Frequent simple fingertip injuries and rare complex injuries induce high costs for society. Such costs should be related to costs for prevention of these injuries.</p

Nerve excitability in the rat forelimb: a technique to improve translational utility

Background Nerve excitability testing by threshold-tracking is the only available method to study axonal ion channel function and membrane potential in the clinical setting. The measures are, however, indirect and the interpretation of neuropathic changes remains challenging. The same multiple measures of axonal excitability were adapted to further explore the pathophysiological changes in rodent disease models under pharmacologic and genetic manipulations. These studies are typically limited to the investigation of the “long nerves” such as the tail or the tibial nerves. New method We introduce a novel setup to explore the ulnar nerve excitability in rodents. We provide normative ulnar data in 11 adult female Long Evans rats under anaesthesia by comparison with tibial and caudal nerves. Additionally, these measures were repeated weekly on 3 occasions to determine the repeatability of these tests. Results Nerve excitability assessment of ulnar nerve proved to be a longitudinally repeatable measure of axonal function mature in rats, as were measures in tibial and caudal nerves. Comparison with existing method: Ulnar nerve motor excitability measures were different from the caudal and tibial excitability measures. Most notably, ulnar nerve showed the largest threshold changes during both depolarizing and hyperpolarizing threshold electrotonus. Conclusions Ulnar nerves demonstrate a distinct nerve excitability profile than the caudal and tibial nerves which could have functional and pathological implications

Observation of surface gap solitons

We predict, in the framework of a nonlinear discrete model, and demonstrate experimentally in defocusing waveguide arrays, that self-localization near the edge of a photonic lattice can result in the formation of surface gap solitons

Surface gap solitons at fabricated photonic lattice interfaces

We generate surface gap solitons with staggered phase structure at the edge of a semi-infinite LiNbO3 waveguide array with defocusing nonlinearity. We characterize self- localization dynamics and identify the threshold power for soliton formation

Discrete self-trapping vs. defocusing in nonlinear waveguide arrays

We predict a sharp crossover from self-defocusing to discrete localization in photonic lattices with defocusing nonlinearity for increasing index contrast. We demonstrate experimentally discrete self-trapping of light by single site excitation in LiNbO3 waveguide arrays

Observation of two-dimensional lattice interface solitons

We report on the experimental observation of two-dimensional solitons at the interface between square and hexagonal waveguide arrays. In addition to the different symmetry of the lattices, the influence of a varying refractive index modulation depth is investigated. Such variation strongly affects the properties of surface solitons residing at different sides of the interface.Comment: 14 pages, 5 figures, to appear in Optics Letter

Observation of surface solitons in chirped waveguide arrays

We report the observation of surface solitons in chirped semi-infinite waveguide arrays whose waveguides exhibit exponentially decreasing refractive indices. We show that the power threshold for surface wave formation decreases with an increase of the array chirp and that for sufficiently large chirp values linear surface modes are supported.Comment: 12 pages, 3 figures, to appear in Optics Letter

Current trends in the surgical management of Dupuytren’s disease in Europe: an analysis of patient charts

Introduction: Dupuytren's disease (DD) causes progressive digital flexion contracture and is more common in men of European descent. Methods: Orthopaedic and plastic surgeons in 12 European countries (the Czech Republic, Denmark, Finland, France, Germany, Hungary, Italy, The Netherlands, Poland, Spain, Sweden and the UK) with >3 and <30 years experience reviewed the medical charts of five consecutive patients they had treated surgically for DD in 2008. Descriptive statistics are reported. Results: In total, 3,357 patient charts were reviewed. Mean (standard deviation) patient age was 61.9 (10.2) years; 81% were men. At the time of the procedure, 11% of patients were at Tubiana stage Ia (0-20° total flexion); 30%, stage Ib (21-45°); 34%, stage II (46-90°); 17%, stage III (91-135°); and 5%, stage IV (&135°). Percutaneous needle fasciotomy was performed in 10%, fasciotomy in 13%, fasciectomy in 69% and dermofasciectomy (DF) in 6% of patients. After surgery, fingers improved a mean of 1.9 Tubiana stages, and 54% of patients had no nodules or contracture. The rate of reported complications during the procedure was 4% overall (11% in patients undergoing DF). The most common postoperative complications reported were haematoma (8%), wound healing complications (6%) and pain (6%). No postoperative complications were reported in 77% of patients. Conclusions: In this European study of more than 3,000 patients with DD, most patients were diagnosed at Tubiana stage I or II, the majority received fasciectomy and more than half had no nodules or contracture remaining after surgery
