In the early 1970s, the major industrial states were preparing to shift to nuclear fission as their principal source of electrical power. But that change has not occurred. In part, this is due to a growing public recognition that techniques and institutions for management of spent nuclear fuel, separated plutonium, and long-lived radioactive wastes are not yet fully developed. The consequent pressures for resolution have spurred a series of often ill-defined and sometimes contradictory attempts to promote international cooperation and control (...) of hazardous activities. How are these varied suggestions to be compared and evaluated? By what criteria can plans be selected that are likely to be both effective and negotiable? In this study, Gene I. Rochlin, physicist and social scientist, explores the technical, political, and institutional aspects of international nuclear export and fuel cycle policies. He categorizes existing proposals and suggests way to develop new ones that better promote both national and international goals. Dr. Rochlin argues neither for nor against the use of nuclear power or plutonium fuels. Instead, he addresses the question of how international arrangements could be reached that might jointly satisfy the objective of the several key nations, yet not be too difficult to negotiate. He concludes that a major fault has been the tendency to improvise arrangements for specific technical or industrial operations. As a result, overall social and political goals have become the bargaining points for compromise. Yet attempts to simultaneously resolve all problems are unlikely to prove fruitful. Dr. Rochlin suggests instead the formation of institutions organized around more limited social, political, and technical objectives, even at the expense of excluding some nations or omitting some aspects of the nuclear fuel cycle. Only by so doing, he argues, can immediate agreements be reached that preserve the potential for more comprehensive future arrangements without sacrificing industrial, environmental, or nonproliferation goals. This important book will be of interest to scientists, social scientists, government officials, and others concerned with the problems of plutonium management and nuclear wastes. (shrink)

Bohmian mechanics, which is also called the de Broglie-Bohm theory, the pilot-wave model, and the causal interpretation of quantum mechanics, is a version of quantum theory discovered by Louis de Broglie in 1927 and rediscovered by David Bohm in 1952. It is the simplest example of what is often called a hidden variables interpretation of quantum mechanics. In Bohmian mechanics a system of particles is described in part by its wave function, evolving, as usual, according to Schrödinger's equation. However, the (...) wave function provides only a partial description of the system. This description is completed by the specification of the actual positions of the particles. The latter evolve according to the.. (shrink)

This edited volume draws upon Lacanian psychoanalytic theory to examine the conscious and unconscious forces underlying race as a social formation, conceptualizing race, racial identity, and racism in ways that go beyond traditional modes of psychoanalytic thought Featuring contributions from Lacanian scholars from diverse geographical and disciplinary contexts, chapters span a wide breadth of topics including white nationalism and contemporary debates over confederate monuments; emergent theories of race rooted in Afropessimism and postcolonialism; Latinx and other racialized groups; apartheid and American (...) slavery; and applications of Lacan's concepts of the lamella, drive and sexuation to processes of racialization. The collection both reorients readers' understandings of race through its deployment of Lacanian theory and redefines the Lacanian subject through its theorizing of subjectivity in relation to race, racism and racial identification. Lacan and Race will be a definitive text for psychoanalytic theorists and contemporary scholars of race and appeal to readers across the fields of psychology, cultural studies, humanities, politics, and sociology.

For a quarter of a century, the Council for Responsible Genetics has provided a unique historical lens into the modern history, science, ethics, and politics of genetic technologies. Since 1983 the Council has had leading scientists, activists, science writers, and public health advocates researching and reporting on a broad spectrum of issues, including genetically engineered foods, biological weapons, genetic privacy and discrimination, reproductive technologies, and human cloning. Biotechnology in Our Lives examines how these issues affect us daily whether we realize (...) it or not. Written for the nonscientist, it looks at the many applications of genetics on the world around us by posing questions such as: What should we know about genetics and childbirth? Can our genes keep us from qualifying for health insurance? Can gene therapy cure cancer? Is behavior genetically determined? Why would the FBI want our genes? Are foreign genes in our food? And much more Ultimately, this definitive book on the subject also encourages us to think about the social, environmental, and moral ramifications of where this technology is taking us. (shrink)

The introduction of genetically engineered crops in agriculture in the mid-1990s has been heralded as the advent of the Second Green Revolution. Among the expectations were high yields, fewer inputs like pesticides, and new nutritionally enhanced foods. Around the same period that traditional breeding was eclipsed by molecular breeding, the concept of sustainability was introduced into the working lexicon of many disciplines, practitioners, and corporations. This chapter discusses the principles of sustainability and their applications to agriculture, evaluates specific GMOs against (...) the criteria for sustainable agriculture, and argues that GMO crops must be understood within an agro-ecological system.

There is no grander topic for us today, and Wolin's treatment is penetrating, thorough, and authoritative. This is a major work of political theory.

Despite its extraordinary predictive successes, quantum mechanics has, since its inception some seventy years ago, been plagued by conceptual di culties. The basic problem, plainly put, is this: It is not at all clear what quantum mechanics is about. What, in fact, does quantum mechanics describe?

In [3] John S. Bell proposed how to associate particle trajectories with a lattice quantum field theory, yielding what can be regarded as a |Ψ|2-distributed Markov process on the appropriate configuration space. A similar process can be defined in the continuum, for more or less any regularized quantum field theory; such processes we call Bell-type quantum field theories. We describe methods for explicitly constructing these processes. These concern, in addition to the definition of the Markov processes, the efficient calculation of (...) jump rates, how to obtain the process from the processes corresponding to the free and interaction Hamiltonian alone, and how to obtain the free process from the free Hamiltonian or, alternatively, from the one-particle process by a construction analogous to “second quantization.” As an example, we consider the process for a second quantized Dirac field in an external electromagnetic field.

In the last quarter of the nineteenth century, Ludwig Boltzmann explained how irreversible macroscopic laws, in particular the second law of thermodynamics, originate in the time-reversible laws of microscopic physics. Boltzmann’s analysis, the essence of which I shall review here, is basically correct. The most famous criticisms of Boltzmann’s later work on the subject have little merit. Most twentieth century innovations – such as the identification of the state of a physical system with a probability distribution on its phase space, (...) of its thermodynamic entropy with the Gibbs entropy of , and the invocation of the notions of ergodicity and mixing for the justification of the foundations of statistical mechanics – are thoroughly misguided.

For centuries, philosophers have debated the question of free will. Do we make our own choices? Or are we more like rudderless ships drifting on the ocean, buffeted by winds and currents outside ourselves? In TK, research psychologist Ken Sheldon reveals that the way we answer these questions has serious implications for our wellbeing. We may never know for certain whether free will exists, Sheldon argues, but recent studies have found that believing in free will matters-indeed, it's an (...) essential component of psychological health. Freely Determined offers an argument for embracing our capacity to choose our own destiny, and a guide for how we might recognize our freedom and use it wisely. Drawing on his own groundbreaking work on motivation, as well as recent research in personality science and social psychology, Sheldon shows us that far from being in the thrall of animal urges and unconscious biases, we humans are constantly making conscious choices: whether to eat the nachos or the salad, whether to shoot the basketball or pass it to a teammate, whether to take that job or marry that person or write that novella. Indeed, over decades of research, Sheldon has established that seeing ourselves as change-makers in our own lives, and in the world, helps us feel happier and even behave more ethically. By identifying and pursuing our deepest values, he argues, we can set and achieve meaningful goals, ones that will help us and our communities flourish. Offering readers insight into how they can live a more self-directed, satisfying life, Freely Determined demystifies the science of choice and reveals that we are radically free to live with greater purpose.

This is a significantly expanded edition of one of the greatest works of modern political theory. Sheldon Wolin's Politics and Vision inspired and instructed two generations of political theorists after its appearance in 1960. This new edition retains intact the original ten chapters about political thinkers from Plato to Mill, and adds seven chapters about theorists from Marx and Nietzsche to Rawls and the postmodernists. The new chapters, which show how thinkers have grappled with the immense possibilities and dangers (...) of modern power, are themselves a major theoretical statement. They culminate in Wolin's remarkable argument that the United States has invented a new political form, "inverted totalitarianism," in which economic rather than political power is dangerously dominant. In this new edition, the book that helped to define political theory in the late twentieth century should energize, enlighten, and provoke generations of scholars to come. Wolin originally wrote Politics and Vision to challenge the idea that political analysis should consist simply of the neutral observation of objective reality. He argues that political thinkers must also rely on creative vision. Wolin shows that great theorists have been driven to shape politics to some vision of the Good that lies outside the existing political order. As he tells it, the history of theory is thus, in part, the story of changing assumptions about the Good. In the new chapters, Wolin displays all the energy and flair, the command of detail and of grand historical developments, that he brought to this story forty years ago. This is a work of immense talent and intense thought, an intellectual achievement that will endure. (shrink)

By using tissue typing in conjunction with preimplantation genetic diagnosis doctors are able to pick a human embryo for implantation which, if all goes well, will become a “saviour sibling”, a brother or sister capable of donating life-saving tissue to an existing child.This paper addresses the question of whether this form of selection should be banned and concludes that it should not. Three main prohibitionist arguments are considered and found wanting: the claim that saviour siblings would be treated as commodities; (...) a slippery slope argument, which suggests that this practice will lead to the creation of so-called “designer babies”; and a child welfare argument, according to which saviour siblings will be physically and/or psychologically harmed.

We consider an isolated, macroscopic quantum system. Let H be a microcanonical “energy shell,” i.e., a subspace of the system’s Hilbert space spanned by the (finitely) many energy eigenstates with energies between E and E + δE. The thermal equilibrium macro-state at energy E corresponds to a subspace Heq of H such that dim Heq/ dim H is close to 1. We say that a system with state vector ψ H is in thermal equilibrium if ψ is “close” to Heq. (...) We show that for “typical” Hamiltonians with given eigenvalues, all initial state vectors ψ0 evolve in such a way that ψt is in thermal equilibrium for most times t. This result is closely related to von Neumann’s quantum ergodic theorem of 1929. (shrink)

In Bohmian mechanics the distribution |ψ|2 is regarded as the equilibrium distribution. We consider its uniqueness, finding that it is the unique equivariant distribution that is also a local functional of the wave function ψ.

The Great Divide in metaphysical debates about laws of nature is between Humeans, who think that laws merely describe the distribution of matter, and non-Humeans, who think that laws govern it. The metaphysics can place demands on the proper formulations of physical theories. It is sometimes assumed that the governing view requires a fundamental / intrinsic direction of time: to govern, laws must be dynamical, producing later states of the world from earlier ones, in accord with the fundamental direction of (...) time in the universe. In this paper, we propose a minimal primitivism about laws of nature (MinP) according to which there is no such requirement. On our view, laws govern by constraining the physical possibilities. Our view captures the essence of the governing view without taking on extraneous commitments about the direction of time or dynamic production. Moreover, as a version of primitivism, our view requires no reduction / analysis of laws in terms of universals, powers, or dispositions. Our view accommodates several potential candidates for fundamental laws, including the principle of least action, the Past Hypothesis, the Einstein equation of general relativity, and even controversial examples found in the Wheeler-Feynman theory of electrodynamics and retrocausal theories of quantum mechanics. By understanding governing as constraining, non-Humeans who accept MinP have the same freedom to contemplate a wide variety of candidate fundamental laws as Humeans do. (shrink)

Conway and Kochen have presented a “free will theorem” [4, 6] which they claim shows that “if indeed we humans have free will, then [so do] elementary particles.” In a more precise fashion, they claim it shows that for certain quantum experiments in which the experimenters can choose between several options, no deterministic or stochastic model can account for the observed outcomes without violating a condition “MIN” motivated by relativistic symmetry. We point out that for stochastic models this conclusion is (...) not correct, while for deterministic models it is not new. In the way the free will theorem is formulated and proved, it only concerns deterministic models. But Conway and Kochen have argued [4, 5, 6, 7] that “randomness can’t help,” meaning that stochastic models are excluded as well if we insist on the conditions “SPIN”, “TWIN”, and “MIN”. We point out a mistake in their argument. Namely, the theorem is of the form deterministic model with SPIN & TWIN & MIN ⇒ contradiction , (1) and in order to derive the further claim, which is of the form stochastic model with SPIN & TWIN & MIN ⇒ contradiction , (2) Conway and Kochen propose a method for converting any stochastic model into a deterministic one [4].

Disclosure of financial interests in scientific research is the centerpiece of the new conflict of interest regulations issued by the U.S. Public Health Service and the National Science Foundation that became effective October 1, 1995. Several scientific journals have also established financial disclosure requirements for contributors. This paper measures the frequency of selected financial interests held among authors of certain types of scientific publications and assesses disclosure practices of authors. We examined 1105 university authors (first and last cited) from Massachusetts (...) institutions whose 789 articles, published in 1992, appeared in 14 scientific and medical journals. (shrink)

I will contrast the two main approaches to the foundations of statistical mechanics: the individualist approach and the ensemblist approach. I will indicate the virtues of each, and argue that the conflict between them is perhaps not as great as often imagined.

Bohmian mechanics is arguably the most naively obvious embedding imaginable of Schr¨ odinger’s equation into a completely coherent physical theory. It describes a world in which particles move in a highly non-Newtonian sort of way, one which may at first appear to have little to do with the spectrum of predictions of quantum mechanics. It turns out, however, that as a consequence of the defining dynamical equations of Bohmian mechanics, when a system has wave function ψ its configuration is typically (...) random, with probability density ρ given by |ψ|2, the quantum equilibrium distribution. It also turns out that the entire quantum formalism, operators as observables and all the rest, naturally emerges in Bohmian mechanics from the analysis of “measurements.” This analysis reveals the status of operators as observables in the description of quantum phenomena, and facilitates a clear view of the range of applicability of the usual quantum mechanical formulas.

In this paper, I examine the claim that any physical theory will have an extremely limited domain of application because 1) we have to use distinct theories to model different situations in the world and 2) no theory has enough textbook models to handle anything beyond a highly simplified situation. Against the first claim, I show that many examples used to bolster it are actually instances of application of the very same classical theory rather than disjoint theories. Thus, there is (...) a hidden unity to the world of classical physics that is usually overlooked (by, for example, Nancy Cartwright who argues for the claims above). Against the second claim, I show that the practice of classical physics involves an enormous (infinite) number of models the use of which cannot be written off as merely ad hoc. Thus, although classical physics cannot, of course, model every situation in nature, it has a much larger domain than some would have us believe. (shrink)

Ninety-five freshmen each recruited three peers to play a "group bidding game," an N-person prisoner’s dilemma in which anyone could win movie tickets depending on their scores in the game. Prior to playing, all participants completed a measure of prosocial value orientation. Replicating and extending earlier findings (Sheldon and McGregor 2000), our results show that prosocial participants were at a disadvantage within groups. Despite this vulnerability, prosocial participants did no worse overall than asocial participants because a counteracting group-level advantage (...) arose for prosocials, who tended to be concentrated in groups. Implications of this assortative process for the egoism/altruism debate, and for hierarchical selection theory, are discussed. (shrink)

We present a quantum model for the motion of N point particles, implying nonlocal (i.e., superluminal) influences of external fields on the trajectories, that is nonetheless fully relativistic. In contrast to other models that have been proposed, this one involves no additional space-time structure as would be provided by a (possibly dynamical) foliation of space-time. This is achieved through the interplay of opposite microcausal and macrocausal (i.e., thermodynamic) arrows of time. PACS numbers 03.65.Ud; 03.65.Ta; 03.30.+p..

It is often claimed that the bulk of the laws of physics –including such venerable laws as Universal Gravitation– are violated in many (or even all) circumstances because they havecounter-instances that result when a system is not isolated fromother systems. Various accounts of how one should interpretthese (apparently) violated laws have been provided. In thispaper, I examine two accounts of (apparently) violated laws, thatthey are merely ceteris paribus laws and that they aremanifestations of capacities. Through an examination of theprimary example (...) that motivated these views, I show that given aproper understanding of the situation, neither view is optimalbecause the law is not even apparently violated. Along the way, Iam able to diagnose what has led to the mistaken belief: I showthat it originates from an element of the standard empiricistconception of laws. I then evaluate the suggestions of how tointerpret violated laws with respect to other examples and findthem wanting there too. (shrink)

This book examines Aristotle's metaphysics and his account of nature, stressing the ways in which his desire to explain observed natural processes shaped his philosophical thought. It departs radically from a tradition of interpretation, in which Aristotle is understood to have approached problems with a set of abstract principles in hand, principles derived from critical reflection on the views of his predecessors. A central example of the book interprets Aristotle's essentialism as deriving from an examination of the kinds of unity (...) that various sorts of things have: elemental motion, alteration, transformation and the growth of organisms. An important conclusion of this argument is that an essence may, under certain circumstances, lack some of its essential attributes. This is a major re-evaluation of Aristotle's metaphysics that will interest philosophers, classicists and historians of science. (shrink)

The renewed interest in the foundations of quantum statistical mechanics in recent years has led us to study John von Neumann’s 1929 article on the quantum ergodic theorem. We have found this almost forgotten article, which until now has been available only in German, to be a treasure chest, and to be much misunderstood. In it, von Neumann studied the long-time behavior of macroscopic quantum systems. While one of the two theorems announced in his title, the one he calls the (...) “quantum H-theorem,” is actually a much weaker statement than Boltzmann’s classical H-theorem, the other theorem, which he calls the “quantum ergodic theorem,” is a beautiful and very non-trivial result. It expresses a fact we call “normal typicality” and can be summarized as follows: For a “typical” finite family of commuting macroscopic observables, every initial wave function ψ0 from a micro-canonical energy shell so evolves that for most times t in the long run, the joint probability distribution of these observables obtained from ψt is close to their micro-canonical distribution.

This study examines the extent to which scientific and biomedical journals have adopted conflict of interest (COI) policies for authors, and whether the adoption and content of such policies leads to the publishing of authors’ financial interest disclosure statements by such journals. In particular, it reports the results of a survey of journal editors about their practices regarding COI disclosures. About 16 percent of 1396 highly ranked scientific and biomedical journals had COI policies in effect during 1997. Less than 1 (...) percent of the articles published during that year in the journals with COI policies contained any disclosures of author personal financial interests while nearly 66 percent of the journals had zero disclosures of author personal financial interests. Nearly three fourths of journal editors surveyed usually publish author disclosure statements suggesting that low rates of personal financial disclosures are either a result of low rates of author financial interest in the subject matter of their publications or poor compliance by authors to the journals’ COI policies.
