    Embracing Power Roles Naturally: Rand's Nietzschean Heroes and Villains.Robert Powell - 2009 - Journal of Ayn Rand Studies 10 (2):371 - 398.
    Because of Ayn Rand's problematic moral labels on her characters, Gail Wynand, not Howard Roark, should be her true Nietzschean hero. Wynand meets the criteria of both the Nietzschean Superman and Rand's Objectivism. Roark's false integrity taints his greatness and improperly vulgarizes him as a Nietzschean Superman. Rand problematically wants her heroes to accept the greatness of the Übermensch, but reject his natural existence and will to power. Dominique Francon should be her true Nietzschean villain, because, unlike Ellsworth Toohey, she (...)

    Isotope Ratios and Chemical Analysis of the 1957 Brazilian Ubatuba Fragment.Robert M. Powell, Michael Swords, Mark Rodeghier & Phyllis Budinger - 2022 - Journal of Scientific Exploration 36 (1).
    A sample from the Ubatuba fragment collected in Brazil in 1957 was tested with the intent of examining the isotope ratios of its primary element, magnesium, and the trace elements strontium, barium, copper, and zinc. As background, the history of chemical testing of the Ubatuba fragments during the 1960s-1980s at multiple labs with varying capabilities is reviewed and then the remainder of the paper examines recent tests completed in 2017 and 2018 that for the first time used HR-ICPMS techniques to (...)

    Taking Pieces of Rand with Them: Ayn Rand's Literary Influence.Robert Powell - 2012 - Journal of Ayn Rand Studies 12 (2):207 - 235.
    Despite the fact that Ayn Rand did not influence the best artists, she did leave an important legacy for the American imagination and literary establishment. Rand's influence is arguably more multi-genre than any other author. Some multi-genre authors who were possibly influenced by Rand include: John Steinbeck (literature), Mickey Spillane and Ian Fleming (detective fiction), Ira Levin, Cameron Hawley, Erika Holzer and Kay Nolte Smith (popular fiction) and Terry Goodkind (science fiction). Her influence represents an important balance between many various (...)
