Under the common-law "tort" or fault-finding system, after an accident between Smith and Jones, if Smith is an "innocent" party claiming loss against a "wrongdoer," he is paid not only for his economic loss, but for the monetary value of his pain and suffering. But it is often very difficult to establish not only who was at fault in an accident but the pecuniary value of pain. Under the no-fault solution, after an accident between Smith and Jones, each is paid for eco nomic losses by his own insurance company, regardless of any one's fault. As a corollary, each is required to surrender his claim based on fault against the other. No-fault insurance then, was designed to make the following improvements in auto accident compensation: (1) to assure that everyone injured in auto accidents is eligible for auto insurance payments, regard less of whether he was able to prove fault-based claims; (2) to spend less on smaller, relatively trivial claims, and more on serious injury; (3) to pay claims promptly; (4) to pay more efficiently by using less of the premium dollar on insurance overhead and legal fees; (5) to reduce, or at least to stabilize, the pertinent costs of auto insurance. In essence, no-fault auto insurance has succeeded in all these goals. Consideration is given to extending no-fault to all kinds of accidents.

Under the common-law tort or fault-finding system, the innocent party in an accident between two persons can claim damages from the wrongdoer not only for economic losses but for pain & suffering. It is often difficult, however, to determine who was at fault or to place a monetary value on pain. Under the no-fault system, both parties are paid by their own insurance companies, & are required to surrender claims against each other. No-fault insurance was intended to assure that everyone injured in auto accidents receives insurance payments, to spend less on smaller claims & more on serious injury, to pay claims promptly, to reduce insurance company overhead on legal fees, & to stabilize costs. That it has achieved these goals with auto insurance suggests its applicability for other kinds of accidents. Modified HA.

This Element is a philosophical history of Social Darwinism. It begins by discussing the meaning of the term, moving then to its origins, paying particular attention to whether it is Charles Darwin or Herbert Spencer who is the true father of the idea. It gives an exposition of early thinking on the subject, covering Darwin and Spencer themselves and then on to Social Darwinism as found in American thought, with special emphasis on Andrew Carnegie, and Germany with special emphasis on Friedrich von Bernhardi. Attention is also paid to outliers, notably the Englishman Alfred Russel Wallace, the Russian Peter Kropotkin, and the German Friedrich Nietzsche. From here we move into the twentieth century looking at Adolf Hitler - hardly a regular Social Darwinian given he did not believe in evolution - and in the Anglophone world, Julian Huxley and Edward O. Wilson, who reflected the concerns of their society.

The concentrations of high- and low-density-lipoprotein cholesterol and triglycerides are influenced by smoking, but it is unknown whether genetic associations with lipids may be modified by smoking. We conducted a multi-ancestry genome-wide gene–smoking interaction study in 133,805 individuals with follow-up in an additional 253,467 individuals. Combined meta-analyses identified 13 new loci associated with lipids, some of which were detected only because association differed by smoking status. Additionally, we demonstrate the importance of including diverse populations, particularly in studies of interactions with lifestyle factors, where genomic and lifestyle differences by ancestry may contribute to novel findings. © 2019, This is a U.S. government work and not under copyright protection in the U.S.; foreign copyright protection may apply. ; This project was largely supported by a grant from the US National Heart, Lung, and Blood Institute of the National Institutes of Health (R01HL118305) and by the Intramural Research Program of the National Human Genome Research Institute of the National Institutes of Health through the Center for Research on Genomics and Global Health (CRGGH).

BACKGROUND AND PURPOSE: Polymorphisms in coagulation genes have been associated with early-onset ischemic stroke. Here we pursue an a priori hypothesis that genetic variation in the endothelial-based receptors of the thrombomodulin-protein C system (THBD and PROCR) may similarly be associated with early-onset ischemic stroke. We explored this hypothesis utilizing a multi-stage design of discovery and replication. METHODS: Discovery was performed in the Genetics-of-Early-Onset Stroke (GEOS) Study, a biracial population-based case-control study of ischemic stroke among men and women aged 15-49 including 829 cases of first ischemic stroke (42.2% African-American) and 850 age-comparable stroke-free controls (38.1% African-American). Twenty-four single-nucleotide-polymorphisms (SNPs) in THBD and 22 SNPs in PROCR were evaluated. Following LD pruning (r2≥0.8), we advanced uncorrelated SNPs forward for association analyses. Associated SNPs were evaluated for replication in an early-onset ischemic stroke population (onset-age<60 years) consisting of 3676 cases and 21118 non-stroke controls from 6 case-control studies. Lastly, we determined if the replicated SNPs also associated with older-onset ischemic stroke in the METASTROKE data-base. RESULTS: Among GEOS Caucasians, PROCR rs9574, which was in strong LD with 8 other SNPs, and one additional independent SNP rs2069951, were significantly associated with ischemic stroke (rs9574, OR = 1.33, p = 0.003; rs2069951, OR = 1.80, p = 0.006) using an additive-model adjusting for age, gender and population-structure. Adjusting for risk factors did not change the associations; however, associations were strengthened among those without risk factors. PROCR rs9574 also associated with early-onset ischemic stroke in the replication sample (OR = 1.08, p = 0.015), but not older-onset stroke. There were no PROCR associations in African-Americans, nor were there any THBD associations in either ethnicity. CONCLUSION: PROCR polymorphisms are associated with early-onset ischemic stroke in Caucasians. ; This study was supported in part by NIH grants U01 NS069208, R01 NS100178, and R01 NS105150; an Epidemiology of Aging Training Program Grant, NIH/NIA T32 AG000262; the U.S. Department of Veterans Affairs, and the American Heart Association Cardiovascular Genome-Phenome Study (grant# 15GPSPG23770000), and an American Heart Association Discovery Grant supported by Bayer Group (grant# 17IBDG33700328).

Lean body mass, consisting mostly of skeletal muscle, is important for healthy aging. We performed a genome-wide association study for whole body (20 cohorts of European ancestry with n = 38,292) and appendicular (arms and legs) lean body mass (n = 28,330) measured using dual energy X-ray absorptiometry or bioelectrical impedance analysis, adjusted for sex, age, height, and fat mass. Twenty-one single-nucleotide polymorphisms were significantly associated with lean body mass either genome wide (p < 5 x 10(-8)) or suggestively genome wide (p < 2.3 x 10(-6)). Replication in 63,475 (47,227 of European ancestry) individuals from 33 cohorts for whole body lean body mass and in 45,090 (42,360 of European ancestry) subjects from 25 cohorts for appendicular lean body mass was successful for five single-nucleotide polymorphisms in/ near HSD17B11, VCAN, ADAMTSL3, IRS1, and FTO for total lean body mass and for three single-nucleotide polymorphisms in/ near VCAN, ADAMTSL3, and IRS1 for appendicular lean body mass. Our findings provide new insight into the genetics of lean body mass. ; NIH [N01 AG 12100, U01 HL72515, U01 GM074518, R01 HL088119, R01 AR046838, U01 HL084756, N01-AG-12100, U24AG051129]; NIA Intramural Research Program, Hjartavernd (the Icelandic Heart Association); Althingi (the Icelandic Parliament); Mid-Atlantic Nutrition and Obesity Research Center of Maryland [P30 DK072488]; NIH/NIAMS [F32AR059469]; American Heart Association [10SDG2690004]; NHLBI [N01-HC-85079, N01-HC-85080, N01-HC-85081, N01-HC-85082, N01-HC-85083, N01-HC-85084, N01-HC-85085, N01-HC-85086, N01-HC-35129, N01 HC-15103, N01 HC-55222, N01-HC-75150, N01-HC-45133, N01-HC-85239, HL080295, HL087652, HL105756, HL103612, HL120393, HL130114]; NINDS; NIA [AG-023629, AG-15928, AG-20098, AG-027058, 1R01AG032098-01A1]; National Center for Research Resources [UL1RR033176]; CTSI [UL1TR000124]; National Institute of Diabetes and Digestive and Kidney Disease grant [DK063491]; Southern California Diabetes Endocrinology Research Center; GlaxoSmithKline; Faculty of Biology and Medicine of Lausanne; Swiss National Science Foundation [33CSCO-122661, 33CS30-139468, 33CS30-148401]; deCODE Genetics, ehf; Cancer Research United Kingdom; Medical Research Council; EU [LSHM-CT-2003-503041]; Wellcome Trust [WT098051, WT089062, WT098017]; Netherlands Organisation for Scientific Research (NWO); Erasmus MC; Centre for Medical Systems Biology (CMSB); European Community's Seventh Framework Programme (FP7), ENGAGE Consortium [HEALTH-F4-2007-201413]; Wellcome Trust; Support for Science Funding programme; CamStrad; Danish Council for Independent Research [DFF-1333-00124, DFF-1331-00730B]; US National Institute for Arthritis, Musculoskeletal and Skin Diseases; National Institute on Aging [U24AG051129, R01 AR 41398, R01AR057118]; FP7-PEOPLE-Marie Curie Career Integration Grants (CIG); National Heart, Lung, and Blood Institute's Framingham Heart Study [N01-HC-25195]; Affymetrix, Inc.
