Compensation for Non-Economic Loss, the Tort-Liability Insurance System, and the 21st Century

Les indemnités pour préjudice moral ont connu une hausse exponentielle aux États-Unis depuis la reconnaissance de ce préjudice il y a environ 150 ans. Les tribunaux ont non seulement étendu les cas où de tels montants peuvent être réclamés, mais ils ont également élargi la définition des notions de « souffrances et douleurs ». Cette évolution s'explique en partie par l'organisation du système judiciaire après la Révolution américaine, par le rôle joué en ce domaine par les avocats et par le niveau de richesse du pays. En conséquence, les indemnités pour préjudice moral ont pris une place de plus en plus importante en droit américain, place qui n'augure rien de bon quant aux chances de voir adopter des régimes d'assurance automobile sans égard à la responsabilité qui réduiraient ces indemnités. Le présent texte donne un aperçu des facteurs qui ont historiquement influé sur le droit de l'assurance responsabilité aux États-Unis et résume les développements plus récents en matière de compensation du préjudice moral. L'auteur s'interroge ensuite sur les possibilités d'adoption d'une loi fédérale présentement à l'étude devant le Congrès américain, loi qui accorde aux victimes de la route le droit d'être indemnisées sans égard à la responsabilité, en échange d'une renonciation préalable au droit de réclamer une indemnité pour préjudice moral. Finalement, l'auteur met de l'avant des propositions de réforme envisageables en matière de responsabilité civile aux États-Unis, à l'aube du 21e siècle.Tort awards for non-economic loss have grown in an almost geometric progression in the United States since first recognized nearly 150 years ago. Not only have courts constantly expanded the areas in which claimants are permitted to recover pain and suffering awards, but at the same time they have liberalized the definition of pain and suffering itself This may be traced in part from the way the judicial system was designed after the American Revolution, the role of lawyers in the system, and the affluence of the country. Consequently, awards for non-economic loss have taken on ever increasing importance, an importance that does not bode well for the prospects for future adoptions of no-fault auto insurance plans that would curtail such recoveries. This article sketches historical influences on the tort-liability insurance system and summarizes modern developments in the law of damages for non-economic loss in the United States. It then raises questions regarding the prospects for adoption of the federal Choice No-Fault Auto Reform Act now pending in the U.S. Congress, a plan that would offer auto accident victims the choice of being compensated on a no-fault basis, while waiving their right to recover for pain and suffering. It concludes by offering a possible scenario of how future efforts to reform the tort-liability system in the United States may occur as we move into the 21st century

The Tort of Bad Faith in First-Party Insurance Transactions: Refining the Standard of Culpability and Reformulating the Remedies by Statute

This Article explores the common-law and statutory background of the tort of bad faith in first-party insurance situations analyzes the varying standards of culpability that have been developed by the courts and suggests a uniform statutory solution to the problems created by the varying standards. The statute also tailors the remedies more closely to the particular type of insurer wrongdoing. The proposed remedies recognize the dual nature of the insurer-insured relationship, that is, one based upon contract and tort concepts. Such a statute would eliminate many of the ambiguities and other deficiencies in the common law of those states that already have adopted the new tort. In addition, the proposed statutory solution would provide clear guidelines to those states where the courts so far have refused to adopt the new tort or have not faced all of the issues

Arc and path consistency revisited

Journal ArticleMackworth and Freuder have analyzed the time complexity of several constraint satisfaction algorithms [4]. We present here new algorithms for arc and path consistency and show that the arc consistency algorithm is optimal in time complexity and of the same order space complexity as the earlier algorithms. A refined solution for the path consistency problem is proposed. However, the space complexity of the path consistency algorithm makes it practicable only for small problems. These algorithms are the result of the synthesis techniques used in ALICE (a general constraint satisfaction system) and local consistency methods

Prospects for Nonlinear Laser Diagnostics in the Jet Noise Laboratory

Two experiments were conducted to test whether optical methods, which rely on laser beam coherence, would be viable for off-body flow measurement in high-density, compressible-flow wind tunnels. These tests measured the effects of large, unsteady density gradients on laser diagnostics like laser-induced thermal acoustics (LITA). The first test was performed in the Low Speed Aeroacoustics Wind Tunnel (LSAWT) of NASA Langley Research Center's Jet Noise Laboratory (JNL). This flow facility consists of a dual-stream jet engine simulator (with electric heat and propane burners) exhausting into a simulated flight stream, reaching Mach numbers up to 0.32. A laser beam transited the LSAWT flow field and was imaged with a high-speed gated camera to measure beam steering and transverse mode distortion. A second, independent test was performed on a smaller laboratory jet (Mach number < 1.2 and mass flow rate < 0.1 kg/sec). In this test, time-averaged LITA velocimetry and thermometry were performed at the jet exit plane, where the effect of unsteady density gradients is observed on the LITA signal. Both experiments show that LITA (and other diagnostics relying on beam overlap or coherence) faces significant hurdles in the high-density, compressible, and turbulent flow environments similar to those of the JNL

1 Versus 2-cm Excision Margins for pT2-pT4 Primary Cutaneous Melanoma (MelMarT): A Feasibility Study

Abstract Background There is a lack of consensus regarding optimal surgical excision margins for primary cutaneous melanoma &gt; 1 mm in Breslow thickness (BT). A narrower surgical margin is expected to be associated with lower morbidity, improved quality of life (QoL), and reduced cost. We report the results of a pilot international study (MelMarT) comparing a 1 versus 2-cm surgical margin for patients with primary melanoma &gt; 1 mm in BT. Methods This phase III, multicentre trial [NCT02385214] administered by the Australia &amp; New Zealand Medical Trials Group (ANZMTG 03.12) randomised patients with a primary cutaneous melanoma &gt; 1 mm in BT to a 1 versus 2-cm wide excision margin to be performed with sentinel lymph node biopsy. Surgical closure technique was at the discretion of the treating surgeon. Patients’ QoL was measured (FACT-M questionnaire) at baseline, 3, 6, and 12 months after randomisation. Results Between January 2015 and June 2016, 400 patients were randomised from 17 centres in 5 countries. A total of 377 patients were available for analysis. Primary melanomas were located on the trunk (56.9%), extremities (35.6%), and head and neck (7.4%). More patients in the 2-cm margin group required reconstruction (34.9 vs. 13.6%; p &lt; 0.0001). There was an increased wound necrosis rate in the 2-cm arm (0.5 vs. 3.6%; p = 0.036). After 12 months’ follow-up, no differences were noted in QoL between groups. Discussion This pilot study demonstrates the feasibility of a large international RCT to provide a definitive answer to the optimal excision margin for patients with intermediate- to high-risk primary cutaneous melanoma. </jats:sec

Wild-type sTREM2 blocks Aβ aggregation and neurotoxicity, but the Alzheimer's R47H mutant increases Aβ aggregation.

TREM2 is a pattern recognition receptor, expressed on microglia and myeloid cells, detecting lipids and Aβ and inducing an innate immune response. Missense mutations (e.g., R47H) of TREM2 increase risk of Alzheimer's disease (AD). The soluble ectodomain of wild-type TREM2 (sTREM2) has been shown to protect against AD in vivo, but the underlying mechanisms are unclear. We show that Aβ oligomers bind to cellular TREM2, inducing shedding of the sTREM2 domain. Wild-type sTREM2 bound to Aβ oligomers (measured by single-molecule imaging, dot blots, and Bio-Layer Interferometry) inhibited Aβ oligomerization and disaggregated preformed Aβ oligomers and protofibrils (measured by transmission electron microscopy, dot blots, and size-exclusion chromatography). Wild-type sTREM2 also inhibited Aβ fibrillization (measured by imaging and thioflavin T fluorescence) and blocked Aβ-induced neurotoxicity (measured by permeabilization of artificial membranes and by loss of neurons in primary neuronal-glial cocultures). In contrast, the R47H AD-risk variant of sTREM2 is less able to bind and disaggregate oligomeric Aβ but rather promotes Aβ protofibril formation and neurotoxicity. Thus, in addition to inducing an immune response, wild-type TREM2 may protect against amyloid pathology by the Aβ-induced release of sTREM2, which blocks Aβ aggregation and neurotoxicity. In contrast, R47H sTREM2 promotes Aβ aggregation into protofibril that may be toxic to neurons. These findings may explain how wild-type sTREM2 apparently protects against AD in vivo and why a single copy of the R47H variant gene is associated with increased AD risk.European Unio
