    In the US, female physicians have lower hourly incomes than their male counterparts, across specialties and after adjusting for physician and practice characteristics; however, female physicians work fewer hours than their male counterparts. We wanted to determine whether a simple method of valuing leisure time - overtime pay - might help explain sex-based wage gaps among US primary care physicians. Therefore, we used Community Tracking Study Physician Survey data from 1996-2005 to model the impact of overtime pay on sex-based wage gaps. As overtime premiums increased in our models, sex-based wage disparities decreased: they become statistically insignificant when overtime wages reached 0%, 32%, and 61% premiums using the ordinary least squared model and with 0%, 62%, and 55% premiums using the propensity score weighted model, for internal medicine, family practice, and pediatric physicians, respectively. We conclude that modest overtime premiums reduced sex-based hourly wage gaps for the salaried primary care physicians we examined. Future analyses of sex-based wage gaps should account for leisure time and its trade for work hours when it becomes scarce

    Statutory Reform to Protect Migrations as Phenomena of Abundance

    Animal migrations capture the human mind and heart like few other natural phenomena. Migrations provide ecological, psychological (e.g., aesthetic), cultural, and economic benefits. Increasingly, though, migrations are being recognized as threatened phenomena-that is, spectacular aspects of the life history of animal species often involving large numbers of individuals, but which are threatened with impoverishment or demise, even though the species per se may not be in peril. Migration phenomena are themselves worthy of protection, as a category of biodiversity Yet, conserving migratory populations and their migrations is particularly problematic. Migratory animals are especially vulnerable to a variety of threats because they come into contact with multiple ecosystems and jurisdictions, tend to congregate in large numbers in discrete and often vulnerable areas, and require considerable fuel for their long-distance journeys. In addition, migration is essentially a phenomenon of abundance-the benefits and values of migrations depend on an abundance of animals taking part and conserving species\u27 populations before they become rare has always been an uphill battle. This Article presents an idea for a new federal law that reflects the perspective that conserving migratory behaviors and processes as phenomena of value in and of themselves, and not only of value for species persistence, can provide unique and important benefits. Current conservation laws generally serve the species-based conservation perspective and, with a few exceptions, are not designed or implemented to protect benefits of abundant animal migrations. The existing fragmented framework of laws and authorities also is insufficient to protect most migratory populations against a diversity of threats across multiple jurisdictions and broad geographic scales. Our proposed federal law would offer a unified framework, require abundance targets, and authorize a comprehensive set of legal tools, including both carrots and sticks, for conserving a limited set of nationally or regionally significant migrations. Such a law would likely improve the current situation for the nation\u27s most notable migratory populations and generally promote the conservation of all migrations as phenomena of abundance

    Space Station Freedom automation and robotics: An assessment of the potential for increased productivity

    Get PDF
    This report presents the results of a study performed in support of the Space Station Freedom Advanced Development Program, under the sponsorship of the Space Station Engineering (Code MT), Office of Space Flight. The study consisted of the collection, compilation, and analysis of lessons learned, crew time requirements, and other factors influencing the application of advanced automation and robotics, with emphasis on potential improvements in productivity. The lessons learned data collected were based primarily on Skylab, Spacelab, and other Space Shuttle experiences, consisting principally of interviews with current and former crew members and other NASA personnel with relevant experience. The objectives of this report are to present a summary of this data and its analysis, and to present conclusions regarding promising areas for the application of advanced automation and robotics technology to the Space Station Freedom and the potential benefits in terms of increased productivity. In this study, primary emphasis was placed on advanced automation technology because of its fairly extensive utilization within private industry including the aerospace sector. In contrast, other than the Remote Manipulator System (RMS), there has been relatively limited experience with advanced robotics technology applicable to the Space Station. This report should be used as a guide and is not intended to be used as a substitute for official Astronaut Office crew positions on specific issues

    Inequity in access to personalized medicine in France: Evidences from analysis of geo variations in the access to molecular profiling among advanced non-small-cell lung cancer patients: Results from the IFCT Biomarkers France Study

    In this article, we studied geographic variation in the use of personalized genetic testing for advanced non-small cell lung cancer (NSCLC) and we evaluated the relationship between genetic testing rates and local socioeconomic and ecological variables. We used data on all advanced NSCLC patients who had a genetic test between April 2012 and April 2013 in France in the frame of the IFCT Biomarqueurs-France study (n = 15814). We computed four established measures of geographic variation of the sex-adjusted rates of genetic testing utilization at the “départment” (the French territory is divided into 94 administrative units called ‘départements’) level. We also performed a spatial regression model to determine the relationship between département-level sex-adjusted rates of genetic testing utilization and economic and ecological variables. Our results are the following: (i) Overall, 46.87% lung cancer admission patients obtained genetic testing for NSCLC; département-level utilization rates varied over 3.2-fold. Measures of geographic variation indicated a relatively high degree of geographic variation. (ii) there was a statistically significant relationship between genetic testing rates and per capita supply of general practitioners, radiotherapists and surgeons (negative correlation for the latter); lower genetic testing rates were also associated with higher local poverty rates. French policymakers should pursue effort toward deprived areas to obtain equal access to personalized medicine for advanced NSCLC patients

    Ordered subset linkage analysis supports a susceptibility locus for age-related macular degeneration on chromosome 16p12

    BACKGROUND: Age-related macular degeneration (AMD) is a complex disorder that is responsible for the majority of central vision loss in older adults living in developed countries. Phenotypic and genetic heterogeneity complicate the analysis of genome-wide scans for AMD susceptibility loci. The ordered subset analysis (OSA) method is an approach for reducing heterogeneity, increasing statistical power for detecting linkage, and helping to define the most informative data set for follow-up analysis. OSA assesses the linkage evidence in subsets of potentially more homogeneous families by rank-ordering family-specific lod scores with respect to trait-associated covariates or phenotypic features. Here, we present results of incorporating five continuous covariates into our genome-wide linkage analysis of 389 microsatellite markers in 62 multiplex families: Body mass index (BMI), systolic (SBP) and diastolic (DBP) blood pressure, intraocular pressure (IOP), and pack-years of cigarette smoking. Chromosome-wide significance of increases in nonparametric multipoint lod scores in covariate-defined subsets relative to the overall sample was assessed by permutation. RESULTS: Using a correction for testing multiple covariates, statistically significant lod score increases were observed for two chromosomal regions: 14q13 with a lod score of 3.2 in 28 families with average IOP ≤ 15.5 (p = 0.002), and 6q14 with a lod score of 1.6 in eight families with average BMI ≥ 30.1 (p = 0.0004). On chromosome 16p12, nominally significant lod score increases (p ≤ 0.05), up to a lod score of 2.9 in 32 families, were observed with several covariate orderings. While less significant, this was the only region where linkage evidence was associated with multiple clinically meaningful covariates and the only nominally significant finding when analysis was restricted to advanced forms of AMD. Families with linkage to 16p12 had higher averages of SBP, IOP and BMI and were primarily affected with neovascular AMD. For all three regions, linkage signals at or very near the peak marker have previously been reported. CONCLUSION: Our results suggest that a susceptibility gene on chromosome 16p12 may predispose to AMD, particularly to the neovascular form, and that further research into the previously suggested association of neovascular AMD and systemic hypertension is warranted
