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 (...) the time the supertask is due to be completed, or else they rely on the application of the time-reversal transformation to states which are not well-defined. Consequently, it is unjustified to conclude that the paradoxical results are arising from within the framework of Newtonian mechanics. In the last part of this article, we discuss various aspects of the physics of these supertasks. (shrink)

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 (...) discussing motion, only intervals, rather than instants, of time are meaningful. The approach presented here reconciles resolutions of the paradoxes based on considering a finite number of acts with those based on analysis of the full infinite set Zeno seems to require. The paper concludes with a brief discussion of the classical and quantum mechanics of performing an infinite number of acts in a finite time. (shrink)

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 (...) distinguishing genetic from nongenetic tests. In addition, barring the use by insurance companies of a genetic test but not a nongenetic test (conceivably for the same multifactorial disease) raises issues of fairness in health insurance. These arguments suggest that ultimately the problems arising from genetic discrimination cannot be solved by narrowly focused legislation but only by a modification of the entire health care system.

The rapidly changing field of genetics affects society through advances in health-care and through implications of genetic research. This study addresses the impacts of new genetic discoveries and technologies on different segments of today's society. The book begins with a chapter on genetic complexity, and subsequent chapters discuss moral and ethical questions arising from today's genetics from the perspectives of health care professionals, the media, the general public, special interest groups and commercial interests.

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 (...) Huntington disease and hemochromatosis, and to asymptomatic carriers of single gene disorders such as cystic fibrosis. Although many such single gene conditions exist, the total incidence of these conditions in the U.S. population is less than 0.4 percent. However, the question concerning the applicability of the ADA will become increasingly important because genetic tests will almost certainly be developed in the near future for common multifactorial diseases like diabetes, heart disease, and certain forms of cancer.

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 (...) interested in the social and economic implications of genetic technology realized that such genetic tests could be used by insurance companies to predict which insurance applicants were likely to become ill or even die from these diseases.

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.

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 (...) conditions were surveyed by questionnaire for reports of genetic discrimination. A total of 27,790 questionnaires were sent out by mail. Of 917 responses received, 206 were followed up with telephone interviews. The responses were analyzed regarding circumstances of the alleged discrimination, the institutions involved, issues relating to the redress of grievances, and strategies to avoid discrimination.

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 space, to determine the origin of the strange behavior. This paper provides a common framework for the discussion of both the local and global methods of analysis. Using this single framework, the areas of disagreement and agreement are made explicit. Further examples of supertasks are proposed to illuminate various aspects of the discussion. (shrink)

Yoga has come to be an icon of Indian culture and civilization, and it is widely regarded as being timeless and unchanging. Based on extensive ethnographic research and an analysis of both ancient and modern texts, Yoga in Modern India challenges this popular view by examining the history of yoga, focusing on its emergence in modern India and its dramatically changing form and significance in the twentieth century. Joseph Alter argues that yoga's transformation into a popular activity idolized for (...) its health value is based on modern ideas about science and medicine. Alter centers his analysis on an interpretation of the seminal work of Swami Kuvalayananda, one of the chief architects of the Yoga Renaissance in the early twentieth century. From this point of orientation he explores current interpretations of yoga and considers how practitioners of yogic medicine and fitness combine the ideas of biology, physiology, and anatomy with those of metaphysics, transcendence, and magical power. The first serious ethnographic history of modern yoga in India, this fluently written book is must reading not only for students and scholars but also practitioners who seek a deeper understanding of how yoga developed over time into the exceedingly popular phenomenon it is today.

What must the United States do to remain the global superpower and stop alienating the rest of the world? The author of the bestselling "The Paradox of American Power" has one clear answer: soft power.

The author of Governance in a Globalizing World probes the limits of American power, offering a compelling argument for the world's lone superpower to forge cooperative relationships with nations around the world.

In dynamic epistemic logic and other fields, it is natural to consider relativization as an operator taking sentences to sentences. When using the ideas and methods of dynamic logic, one would like to iterate operators. This leads to iterated relativization. We are also concerned with the transitive closure operation, due to its connection to common knowledge. We show that for three fragments of the logic of iterated relativization and transitive closure, the satisfiability problems are fi1 11–complete. Two of these fragments (...) do not include transitive closure. We also show that the question of whether a sentence in these fragments has a finite (tree) model is fi0 01–complete. These results go via reduction to problems concerning domino systems. (shrink)

Wisdom is peculiarly abstract, ineffable, and yet perennial. It is also temporal, stretching forwards as well is backwards in time. Wisdom is often treated as the outcome of life experience, reflection, discipline, and equanimity. Capturing the Ineffable aims to establish wisdom as an area if inquiry within anthropology and an analytic account of wisdom and its role and focus in anthropology. In addition to developing theories for an anthropology (and excavation) of wisdom, this volume argues collectively that anthropology is especially (...) well suited to engage in questioning what it is that is called wisdom, and how wisdom, as a concept, and an enacted activity, functions in metaphysical and interpersonal experiences, values, and judgements. The contributors include many key US and UK thinkers. (shrink)

It is time for a new paper about open questions in the currently very active area of randomness and computability. Ambos-Spies and Kučera presented such a paper in 1999 [1]. All the question in it have been solved, except for one: is KL-randomness different from Martin-Löf randomness? This question is discussed in Section 6.Not all the questions are necessarily hard—some simply have not been tried seriously. When we think a question is a major one, and therefore likely to be hard, (...) we indicate this by the symbol ▶, the criterion being that it is of considerable interest and has been tried by a number of researchers. Some questions are close contenders here; these are marked by ▷. With few exceptions, the questions are precise. They mostly have a yes/no answer. However, there are often more general questions of an intuitive or even philosophical nature behind. We give an outline, indicating the more general questions.All sets will be sets of natural numbers, unless otherwise stated. These sets are identified with infinite strings over {0, 1}. Other terms used in the literature are sequence and real. (shrink)

We call A weakly low for K if there is a c such that $K^A(\sigma)\geq K(\sigma)-c$ for infinitely many σ; in other words, there are infinitely many strings that A does not help compress. We prove that A is weakly low for K if and only if Chaitin's Ω is A-random. This has consequences in the K-degrees and the low for K (i.e., low for random) degrees. Furthermore, we prove that the initial segment prefix-free complexity of 2-random reals is infinitely (...) often maximal. This had previously been proved for plain Kolmogorov complexity. (shrink)

Solves Vann McGee's counterexample to Modus Ponens within classical logic by disclosing the suppressed premises and bringing them /within/ the argument.

In this volume, Joseph Catalano offers an in-depth exploration of Jean-Paul Sartre's four major philosophical writings: Being and Nothingness, Saint Genet: Actor and Martyr, The Critique of Dialectical Reason, and The Family Idiot. These works have been immensely influential, but they are long and difficult and thus challenging for both students and scholars. Catalano here demonstrates the interrelation of these four works, their internal logic, and how they provide insights into important but overlooked aspects of Sartre's thought, such as (...) the body, childhood, and evil. The book begins with Sartre's final work, The Family Idiot, and systematically works backward to Being and Nothingness. Catalano then repeats the study by advancing chronologically, beginning with Being and Nothingness and ending with The Family Idiot and an afterword on Flaubert's Madame Bovary. Readers will appreciate Catalano's subtle readings as well as the new insights that he brings to Sartre's oeuvre. (shrink)

Sartre’s Critique of Dialectical Reason ranks with Being and Nothingness as a work of major philosophical significance, but it has been largely neglected. The first volume, published in 1960, was dismissed as a Marxist work at a time when structuralism was coming into vogue; the incomplete second volume has only recently been published in France. In this commentary on the first volume, Joseph S. Catalano restores the Critique to its deserved place among Sartre’s works and within philosophical discourse as (...) a whole. Sartre attempts one of the most needed tasks of our times, Catalano asserts—the delivery of history into the hands of the average person. Sartre’s concern in the Critique is with the historical significance of everyday life. Can we, he asks, as individuals or even collectively, direct the course of our history? A historical context for our lives is given to us at birth, but we sustain that context with even our most mundane actions—buying a newspaper, waiting in line, eating a meal. In looking at history, Sartre argues, reason can never separate the historical situation of the investigator from the investigation. Thus reason falls into a dialectic, always depending upon the past for guidance but always being reshaped by the present. Clearly showing the influence of Marx on Sartre’s thought, the Critique adds the historical dimension lacking in Being and Nothingness. In placing the Critique within the corpus of Sartre’s philosophical writings, Catalano argues that it represents a development rather than a break from Sartre’s existentialist phase. Catalano has organized his commentary to follow the Critique and has supplied clear examples and concrete expositions of the most difficult ideas. He explicates the dialogue between Marx and Sartre that is internal to the text, and he also discusses Sartre’s Search for Method, which is published separately from the Critique in English editions.

Medical decision making often utilizes subjective observations to arrive at concrete judgments. The decisions frequently affect who receives scarce medical treatments and, thus, who lives or dies. In this paper, a model health status index is described. It is specific for the problem of choosing patients for hemodialysis or transplantation. Such a health status index may be designed for any medical decision involving such issues as drug treatment priorities, identification of salvageable patients, and selection of patients for scarce medical treatment. (...) This index (1) incorporates a physician''s own medical criteria and values, (2) can be modified as the data base improves, (3) assures consistency from decision to decision, and (4) can be developed and used without the help of a mathematician or computer.

The main purpose of this paper is to bring out some significant humanistic characteristics of Chinese religious thought. My account is limited to what is originally and typically Chinese. That is to say, it will exclude what has been influenced by Buddhism from India or Christianity from the Western world. Some of the theses of this paper are based on scholarly works, while others are drawn from the author's primary experience.

We study reals with infinitely many incompressible prefixes. Call $A \in 2^{\omega}$ Kolmogorot random if $(\exists^{\infty}n) C(A \upharpoonright n) \textgreater n - \mathcal{O}(1)$ , where C denotes plain Kolmogorov complexity. This property was suggested by Loveland and studied by $Martin-L\ddot{0}f$ , Schnorr and Solovay. We prove that 2-random reals are Kolmogorov random. Together with the converse-proved by Nies. Stephan and Terwijn [11]-this provides a natural characterization of 2-randomness in terms of plain complexity. We finish with a related characterization of 2-randomness.
