  1. Newtonian Supertasks: A Critical Analysis.Joseph S. Alper & Mark Bridger - 1998 - Synthese 114 (2):355-369.
    In two recent papers Perez Laraudogoitia has described a variety of supertasks involving elastic collisions in Newtonian systems containing a denumerably infinite set of particles. He maintains that these various supertasks give examples of systems in which energy is not conserved, particles at rest begin to move spontaneously, particles disappear from a system, and particles are created ex nihilo. An analysis of these supertasks suggests that they involve systems that do not satisfy the mathematical conditions required of Newtonian systems at (...)

    Individual, Family, and Societal Dimensions of Genetic Discrimination: A Case Study Analysis. [REVIEW]Lisa N. Geller, Joseph S. Alper, Paul R. Billings, Carol I. Barash, Jonathan Beckwith & Marvin R. Natowicz - 1996 - Science and Engineering Ethics 2 (1):71-88.
    Background. As the development and use of genetic tests have increased, so have concerns regarding the uses of genetic information. Genetic discrimination, the differential treatment of individuals based on real or perceived differences in their genomes, is a recently described form of discrimination. The range and significance of experiences associated with this form of discrimination are not yet well known and are investigated in this study. Methods. Individuals at-risk to develop a genetic condition and parents of children with specific genetic (...)

  3. Mathematics, Models and Zeno's Paradoxes.Joseph S. Alper & Mark Bridger - 1997 - Synthese 110 (1):143-166.
    A version of nonstandard analysis, Internal Set Theory, has been used to provide a resolution of Zeno's paradoxes of motion. This resolution is inadequate because the application of Internal Set Theory to the paradoxes requires a model of the world that is not in accordance with either experience or intuition. A model of standard mathematics in which the ordinary real numbers are defined in terms of rational intervals does provide a formalism for understanding the paradoxes. This model suggests that in (...)

    Distinguishing Genetic From Nongenetic Medical Tests: Some Implications for Antidiscrimination Legislation.Joseph S. Alper & Jon Beckwith - 1998 - Science and Engineering Ethics 4 (2):141-150.
    Genetic discrimination is becoming an increasingly important problem in the United States. Information acquired from genetic tests has been used by insurance companies to reject applications for insurance policies and to refuse payment for the treatment of illnesses. Numerous states and the United States Congress have passed or are considering passage of laws that would forbid such use of genetic information by health insurance companies. Here we argue that much of this legislation is severely flawed because of the difficulty in (...)

    Two Ways of Looking at a Newtonian Supertask.Jon Pérez Laaraudogoitia, Mark Bridger & Joseph S. Alper - 2002 - Synthese 131 (2):173 - 189.
    A supertask is a process in which an infinite number of individuated actions are performed in a finite time. A Newtonian supertask is one that obeys Newton''s laws of motion. Such supertasks can violate energy and momentum conservation and can exhibit indeterministic behavior. Perez Laraudogoitia, who proposed several Newtonian supertasks, uses a local, i.e., particle-by-particle, analysis to obtain these and other paradoxical properties of Newtonian supertasks. Alper and Bridger use a global analysis, embedding the system of particles in a Banach (...)

    Reconsidering Genetic Antidiscrimination Legislation.Jon Beckwith & Joseph S. Alper - 1998 - Journal of Law, Medicine and Ethics 26 (3):205-210.
    Until approximately twenty years ago, advances in the study of human genetics had little influence on the practice of medicine. In the 1980s, this changed dramatically with the mapping of the altered genes that cause cystic fibrosis and Huntington disease. In just a few years, these discoveries led to DNA-based tests that enabled clinicians to determine whether prospective parents were carriers of CF or whether an individual carried the Huntington gene and, as a result, would almost certainly develop the disease.Observers (...)

    Does the ADA Provide Protection Against Discrimination on the Basis of Genotype?Joseph S. Alper - 1995 - Journal of Law, Medicine and Ethics 23 (2):167-172.
    As a consequence of the problems caused by genetic discrimination, federal and state law makers are being pressured to pass a legislative remedy. A primary question is whether the Americans with Disabilities Act of 1990 applies to individuals with a potentially disabling genetic disorder who are pre-symptomatic or asymptomatic and may never become ill and to healthy individuals who are carriers of genetic conditions. At present, this question has relevance principally for individuals with the genotype for single gene disorders, like (...)

    On the Dynamics of Perez Lauraudogoitia's Supertask.Mark Bridger & Joseph S. Alper - 1999 - Synthese 119 (3):325-337.
    The supertasks described by Perez Laraudogoitia, involving the dynamics of a system containing an infinite number of particles in a bounded region of space, are characterized by the nonconservation of energy and by the spontaneous motion of particles. We argue that these features arise from the inadequacy of the local, particle-by-particle description used to analyze the supertasks. A global analysis, involving embeddings in Hilbert spaces, clarifies these supertasks and avoids what we regard as their nonphysical features.
