    Ammoniacal silver stain used for light microscopy was adapted advantageously for use with very thin biological sections required for electron microscopy. Silver stain can be performed in short time, has more contrast, and is especially useful for low power electron microscopy

    The Ugly Truth About Appearance Discrimination and the Beauty of Our Employment Discrimination Law

    Get PDF
    The keynote speaker for the conference begins by reminding the audience that a mere quarter of a century earlier there was no federal law that expressly prohibited discrimination in employment based on physical appearance. Considering the difficulty of crafting and enacting an appearance-based employment discrimination law should lead to a fuller appreciation of not only our employment discrimination laws generally, but also the Americans with Disabilities Act specifically

    Globular Cluster Formation in the Virgo Cluster

    Metal poor globular clusters (MPGCs) are a unique probe of the early universe, in particular the reionization era. Systems of globular clusters in galaxy clusters are particularly interesting as it is in the progenitors of galaxy clusters that the earliest reionizing sources first formed. Although the exact physical origin of globular clusters is still debated, it is generally admitted that globular clusters form in early, rare dark matter peaks (Moore et al. 2006; Boley et al. 2009). We provide a fully numerical analysis of the Virgo cluster globular cluster system by identifying the present day globular cluster system with exactly such early, rare dark matter peaks. A popular hypothesis is that that the observed truncation of blue metal poor globular cluster formation is due to reionization (Spitler et al. 2012; Boley et al. 2009; Brodie & Strader 2006); adopting this view, constraining the formation epoch of MPGCs provides a complementary constraint on the epoch of reionization. By analyzing both the line of sight velocity dispersion and the surface density distribution of the present day distribution we are able to constrain the redshift and mass of the dark matter peaks. We find and quantify a dependence on the chosen line of sight of these quantities, whose strength varies with redshift, and coupled with star formation efficiency arguments find a best fitting formation mass and redshift of 5×108M\simeq 5 \times 10^8 \rm{M}_\odot and z9z\simeq 9. We predict 300\simeq 300 intracluster MPGCs in the Virgo cluster. Our results confirm the techniques pioneered by Moore et al. (2006) when applied to the the Virgo cluster and extend and refine the analytic results of Spitler et al. (2012) numerically.Comment: 13 Pages, 13 Figures, submitted to MNRA

    Faragher, Ellerth, and the Federal Law of Vicarious Liability for Sexual Harassment by Supervisors: Something Lost, Something Gained, and Something to Guard Against

    Get PDF
    In this Essay, the author faces his nightmare exam question: he must define sexual harassment to the satisfaction of several potential graders with different perspectives on sexual harassment law. His valiant effort to justify his response leads him to a discussion of the federal law of vicarious liability for sexual harassment by supervisors after the Supreme Court\u27s recent rejection of tort law respondeat superior analysis for such claims under Title VII. The author argues that, while the rejection of the tort standard for vicarious liability in Title VII claims removes the longstanding connection between Title VII law and state tort law, the result is appropriate given their different objectives. He further warns that, now that the ties between state tort law and Title VII have been severed, courts should not allow developments in sexual harassment cases to unduly influence state respondeat superior law

    Unmasking a Pretext for Res Ipsa Loquitur: A Proposal to Let Employment Discrimination Speak for Itself

    Has too much tort law been incorporated into the case law under the federal employment discrimination statutes? The debate on this issue has been reinvigorated by the Supreme Court’s decision in Staub v. Proctor Hospital, 131 S. Ct. 1186 (2011). In Staub the Court referred to the Uniformed Services Employment and Reemployment Rights Act, a federal employment discrimination statute, as a “federal tort.” The Court then adopted the tort doctrine of proximate cause as the standard for evaluating subordinate bias (or “cat’s paw”) liability. Staub was not the first case in which the Court has suggested that a federal employment discrimination law is a federal statutory tort, but it was the most express and direct statement. Moreover, the Court’s adoption of proximate cause, one of the most complicated, confusing, and criticized concepts in tort law, to analyze a prevalent issue in employment discrimination law is striking and provocative. Staub reinvigorates the debate about whether the Court and courts have imported too much tort law into employment discrimination law—the debate about the “tortification” of employment discrimination law. Most discussions of tortification of discrimination law trace the origin to the Supreme Court’s discussion of torts causation standards in Price Waterhouse v. Hopkins, 490 U.S. 228 (1989). However, it actually began much earlier. The ubiquitous pretext analysis, developed by the Court to analyze individual disparate treatment cases in McDonnell Douglas Corp. v. Green, 411 U.S. 792 (1973), is a thinly veiled version of the tort doctrine res ipsa loquitur. Although there have been numerous critiques of the McDonnell Douglas analysis that have called for its abrogation, none have exposed it as the much-maligned tort doctrine. Evaluating McDonnell Douglas as res ipsa helps explain its weaknesses and shortcomings. After almost forty years of the pretext analysis, it is time to expel it from discrimination law. Abrogating the McDonnell Douglas analysis should be a significant first step in reconsidering the tortification of employment discrimination law
