In lieu of an abstract, here is a brief excerpt of the content:Fallout from Government-Sponsored Radiation ResearchCarol Mason Spicer (bio)On December 28, 1993, Energy Secretary Hazel R. O'Leary publicly appealed to both the executive and legislative branches of the United States Government to consider compensation for individuals who were harmed by their exposure to ionizing radiation while enrolled in government-sponsored studies conducted between 1940 and the early 1970s.1 The call for compensation was issued three weeks after Secretary O'Leary disclosed (...) that radiation experiments involving humans, sometimes without their consent, had occurred under the auspices of the Atomic Energy Commission (AEC), a forerunner of the Department of Energy (DOE). Secretary O'Leary directed her department to investigate the nature and extent of the experiments, report on their medical and ethical acceptability, and locate the research subjects or their families.Background to the Federal Advisory CommitteeDespite the fact that the existence of many government-sponsored radiation experiments was not a secret—much of the research was reported at the time in scientific journals, and in 1986, Representative Edward J. Markey (D-MA) conducted congressional hearings on such radiation research—Secretary O'Leary's disclosure of the AEC experiments and her call for compensation made the experiments common knowledge and sparked a swift and complex governmental response involving both the executive and legislative branches.It is curious that the "radiation experiments" have garnered so much attention now, since they were virtually ignored in the wake of the 1986 hearings. Secretary O'Leary's disclosure of the radiation studies grew out of a general reassessment of secrecy in government. In April 1993, the Clinton administration set out to review the system of government secrecy that evolved during the Cold War, and in May 1993, DOE began reviewing and declassifying files pertaining to nuclear weapons research. When Dan Reicher, a top aide to Secretary O'Leary, informed her in November of the impending publication of an Albuquerque Tribune investigative report (Welsome 1993) on an experiment conducted between 1945 and 1947 in which 18 subjects were injected with plutonium, [End Page 147] the topic of questionable research involving the exposure of human subjects to radiation was added to the DOE list of information to be disclosed. At the time, it was thought to be but one small part of a massive quantity of DOE information to be made public.As part of its effort to investigate the radiation experiments, DOE established a toll-free telephone hot line for individuals who thought they might have been the subjects of radiation exposure experiments. The hot line, originally staffed by three people to handle the anticipated few dozen calls per day, received more than 2,000 calls in the first week. By early January the hot line was flooded with 6,000 to 10,000 calls daily, and its staff had increased more than ten-fold. Although many of the calls were deemed not to be candidates for further investigation, the extent of the radiation-related experiments, sponsored not only by AEC, but also by the military and other government departments and agencies, took officials by surprise.On December 30, the Department of Defense, the Department of Veterans Affairs, and the National Aeronautics and Space Administration all announced that they were initiating thorough reviews of their files to determine the extent and nature of any radiation experiments conducted under their auspices.2 In January, the CIA and the Department of Health and Human Services, including the National Institutes of Health, followed suit.The White House publicly entered the arena in late December announcing that it would hold a meeting on January 3, 1994, to help coordinate the government's investigative effort. At the same time, Senator Edward M. Kennedy (D-MA) called for a mid-January congressional hearing to investigate experiments conducted between 1946 and 1956 in which mentally retarded boys at the Fernald State School in Massachusetts were fed radioactive iron supplements or milk containing radioactive calcium to enable researchers to trace the absorption of those nutrients. Senator Kennedy's hearing, conducted by the Subcommittee on Health of the Senate Committee on Labor and Human Resources, was the first of a number of congressional hearings held earlier this year to investigate the...

This essay introduces a special collection of papers by Angela Creager, Soraya de Chadarevian, Karen Rader, Jean-Paul Gaudillière, and María Jesús Santesmases on the theme "Radiobiology in the Atomic Age.".

Project Chariot, one of the first planned nuclear excavation experiments of the Atomic Energy Commission’s Plowshare program, touched off a controversy over its safety that drew in two prominent American biologists, Paul Sears and Barry Commoner, both now known mainly for their roles as environmental advocates. However, Sears, the ecologist and well-established conservationist, supported Project Chariot and the Plowshare program in general, while Commoner, unacquainted with ecology at the time, strongly opposed it. A close study of their different responses (...) to this project provides insights into the tensions and pressures on scientists during this critical period of the Cold War, 1960–1961, when fear of nuclear war and concerns over radioactive fallout from bomb tests mixed with hopes for peaceful applications of nuclear energy and the environmental movement had not yet begun. For Sears, the close connections in the United States between the science of ecology and the Atomic Energy Commission may well have played a significant role in his support for Chariot, while for Commoner, Project Chariot turned out to be his epiphany moment, the incident that transformed him from an antinuclear activist into an environmentalist.

The National Academy of Science's 1956 study on the Biological Effects of Atomic Radiation (BEAR) was designed to provide an objective analysis to assess conflicting statements by leading geneticists and by officials in the Atomic Energy Commission. Largely because of its status as a detached, non-governmental evaluation by eminent scientists, no studies have had a broader impact on the development of biological thinking in regard to nuclear policies. This paper demonstrates that despite the first BEAR study's reputation as (...) an objective and independent study, it was the product of careful negotiation between Academy scientists, the Atomic Energy Commission, and Britain's Medical Research Council. This paper also reveals the fragility of the consensus that produced the Academy's report, the range of political uses of the report, and the subsequent disaffection of the scientists who took part in it.

The postwar investments by several governments into the development of atomic energy for military and peaceful uses fuelled the fears not only of the exposure to acute doses of radiation as could be expected from nuclear accidents or atomic warfare but also of the long-term effects of low-dose exposure to radiation. Following similar studies pursued under the aegis of the Manhattan Project in the United States, the “genetics experiment” discussed by scientists and government officials in Britain soon after (...) the war, consisted in large-scale low-dose irradiation experiments of laboratory animals to assess the effects of such exposures on humans. The essay deals with the history of that project and its impact on postwar genetics. It argues that radiobiological concerns driven by atomic politics lay at the heart of much genetics research after the war and that the atomic links are crucial to understand how genetics became an overriding concern in the late 20th century.

This paper extends previous arguments against the assumption that the study of variation at the molecular level was instigated with a view to solving an internal conflict between the balance and classical schools of population genetics. It does so by focusing on the intersection of basic research in protein chemistry and the molecular approach to disease with the enactment of global health campaigns during the Cold War period. The paper connects advances in research on protein structure and function as reflected (...) in Christian Anfinsen’s The molecular basis of evolution, with a political reading of Emilé Zuckerkandl and Linus Pauling’s identification of molecular disease and evolution. Beyond atomic fallout, these advances constituted a rationale for the promotion of genetic surveys of human populations in the Third World, in connection with international health programs. Light is shed not only on the experimental roots of the molecular challenge but on the broader geopolitical context where the rising role of biomedicine and public health had an impact on evolutionary biology.

This article examines historical transformations of Japanese collective memory of the atomic bombing of Hiroshima by utilizing a theoretical framework that combines a model of reiterated problem solving and a theory of cultural trauma. I illustrate how the event of the nuclear fallout in March 1954 allowed actors to consolidate previously fragmented commemorative practices into a master frame to define the postwar Japanese identity in terms of transnational commemoration of "Hiroshima." I also show that nationalization of trauma of (...) "Hiroshima" involved a shift from pity to sympathy in structures of feeling about the event. This historical study suggests that a reiterated problem-solving approach can be efficacious in analyzing how construction of national memory of a traumatic event connects with the recurrent reworking of national identity, on the one hand, and how a theory of cultural trauma can be helpful in exploring a synthesis of psychological and sociological approaches to commemoration of a traumatic event, on the other.

The last surviving signatory to the manifesto was Joseph Rotblat, who died on 31 August 2005. In 1995, Rotblat and the Pugwash Conferences were awarded the Nobel Prize for Peace. During World War ii, Joseph Rotblat participated in the Manhattan Project to develop an atomic bomb. An Encyclopaedia Britannica article on his Nobel prize explains that “Although he was uncomfortable about participating in the creation of an atomic bomb, Rotblat initially believed that the weapon would be used only to deter a German threat. After learning in 1944 that it would be used to contain the Soviet Union, a World War ii ally, he left the project….” Upon returning to England in 1945, Rotblat left defence work for medical research. He served as founding secretary-general and later as president of the Pugwash Conferences on Science and World Affairs, which began in 1957 and at which key scientists and others from different countries could confer about the peril of nuclear weapons facing the world. As a medical physicist at London University’s St. Bartholomew’s Hospital Medical College (1950–76), Rotblat directed attention toward the biological hazards of nuclear radiation and the severity of fallout from atmospheric testing. He worked closely with Russell in the 1950s and early ’60s and still visited him in his last years. (See his “Personal Reminiscences”, Russell, 18 [1998]: 5–24.) The book’s co-author, Robert Hinde, is the author of numerous books and articles in psychology. The book addresses the planet’s current state in terms of weapons of mass destruction. It features many tables and charts on matters ranging from the varying levels of the super-powers’ nuclear warhead stockpiles to the principal nuclear arms control treaties to estimates of military deaths in individual wars during the last 60 years. Since this book is an earnest endeavour to address the issue of weapons of mass destruction, many of its most fundamental prescriptions sound basic, even _Russell_ journal (home office): E:CPBRRUSSJOURTYPE2602\REVIEWS.262 : 2007-01-24 01:12 188 Reviews somewhat banal. To be sure, the authors acknowledge that “Any attempt to discuss ways of preventing war must address very basic issues, and in so doing lays itself open to accusations of mushy idealism” (pp. 214–15). In War No More the authors opt to err in the direction of moral truisms as a small price to pay if there is a chance of contributing to a discussion eventually compelling the world’s political leaders to heed such moral considerations. In the prevention of conflict, “Often the success of such efforts may be unknown to the wider world just because the criterion of success is simply that nothing happens” (p. 198). Hinde and Rotblat urge their readers to understand the absolute need to abolish war if humanity is to endure in this nuclear age. Their position is that “the very possession of nuclear weapons is immoral. Their enormous destructive power, inflicted on civilians even more than on the military, would make their use unforgiveable” (p. 139). The authors expressly credit Bertrand Russell and Albert Einstein with having taken the initiative for international action on this front (p. 189). And as was the view of Russell and Einstein 50 years earlier, Hinde and Rotblat proclaim in their book that “The only solution is international agreement on the total abolition of nuclear weapons” (p. 139). Hinde and Rotblat concede the ease with which people can be pessimistic about the prospects of abolishing war. However, the formidable challenge posed by such a task is deemed “no excuse for inaction”. They cite historic instances in which humanity has... (shrink)

Introductory survey -- Atomic theory and mechanics -- The quantum postulate and the recent development of atomic theory -- The quantum of action and the description of nature -- The atomic theory and the fundamental principles underlying the description of nature.

These articles and speeches by the Nobel Prize-winning physicist date from 1934 to 1958. Rather than expositions on quantum physics, the papers are philosophical in nature, exploring the relevance of atomic physics to many areas of human endeavor. Includes an essay in which Bohr and Einstein discuss quantum and_wave equation theories. 1961 edition.

In September 2003, several prominent mutual fund companies came under investigation for illegal trading practices. Allegations suggested these funds allowed certain investors to profit from short-term trading schemes at the expense of other investors. Surprisingly, regulatory authorities have known for more than two decades of the potential for such abuses, yet have taken limited steps to correct the problem. We explore investor reaction to the scandal by measuring assets under management, stock returns, and performance. Mutual funds managed by investigated firms (...) show a substantial decline in post-announcement assets under management. These firms also experienced significantly negative announcement-period returns. Finally, we discuss several policy suggestions to prevent future trading abuses and provide direction for future research. (shrink)

Current DHHS regulations require that policies and procedures developed by institutions to handle allegations of scientific misconduct include provisions for “undertaking diligent efforts to protect the positions and reputations of those persons who, in good faith, make allegations.” Analogously, institutions receiving PHS funds are required to protect the confidentiality of those accused of such misconduct or, failing that, to restore their reputations if the allegations are not confirmed. Based on two surveys, one of whistleblowers and one of individuals accused but (...) exonerated of scientific misconduct, this paper examines how well the system works to protect both sets of participants in cases of alleged misconduct. Contrary to popular impressions created by notorious cases, substantial minorities of both whistleblowers and exonerated scientists experience no adverse outcomes at the time the allegations are made and pursued. During this period, however, whistleblowers report more negative outcomes and more severe negative outcomes than their accused but exonerated counterparts. In the longer run, majorities of both groups report little impact on different aspects of their careers or professional activities, though those who report any impacts generally report negative ones. The accused but exonerated, however, appear to fare worse than whistleblowers in impacts on several aspects of their personal lives; their mental health, physical health, self-esteem, and self-identity.

Although continued investments in nanotechnology are made, atomically precise manufacturing (APM) to date is still regarded as speculative technology. APM, also known as molecular manufacturing, is a token example of a converging technology, has great potential to impact and be affected by other emerging technologies, such as artificial intelligence, biotechnology, and ICT. The development of APM thus can have drastic global impacts depending on how it is designed and used. This paper argues that the ethical issues that arise from APM (...) - as both a standalone technology or as a converging one - affects the roles of stakeholders in such a way as to warrant an alternate means furthering responsible innovation in APM research. This paper introduces a value-based design methodology called Value Sensitive Design (VSD) that may serve as a suitable framework to adequately cater to the values of stakeholders. Ultimately, it is concluded that VSD is a strong candidate framework for addressing the moral concerns of stakeholders during the preliminary stages of technological development. (shrink)

In this working paper, we discuss why researchers and policymakers need to better understand how different theoretical accounts of stability lead to different frameworks of analysis. Though ubiquitously mentioned, stability remains an under-theorized notion in security studies. Expert accounts tend to present stability as a generic description, readily applicable to most political phenomena Ð a stabilized state, a stable region, an unstable society. While seemingly equivocal, such uses exhibit different conceptualizations, exhibiting different features and demanding multiple research programs. To date, (...) most accounts of stability tend to take stability to be an (unconstructed) natural phenomenon or a non-derivative social construction. In this introductory paper, we claim that there is a third way to account for stability that remains unexplored in security studies. Simply put, it involves taking stability to be a derivative social construction (i.e., systemic fallout). We then argue that this alternative account should serve as the theoretical basis for an independent research program within stability studies. (shrink)

The quantum theory of atoms in molecules (QTAIM) uses physics to define an atom and its contribution to observable properties in a given system. It does so using the electron density and its flow in a magnetic field, the current density. These are the two fields that Schrödinger said should be used to explain and understand the properties of matter. It is the purpose of this paper to show how QTAIM bridges the conceptual gulf that separates the observations of chemistry (...) from the realm of physics and do so in a manner that is both rigorous and conceptually simple. Since QTAIM employs real measurable fields, it enables one to present the findings of complex quantum mechanical calculations in a pictorial manner that isolates the essential physics. The time has arrived for a sea change in our attempts to predict and classify the observations of chemistry, time to replace the use of simplified and arbitrary models with the full predictive power of physics, as applied to an atom in a molecule.

This book reexamines the birth of quantum mechanics, in particular examining the development of crucial and original insights of Bohr. In particular, it gives a detailed study of the development and the interpretation given to Bohr's Principle of Correspondence. It also describes the role that this principle played in guiding Bohr's research over the critical period from 1920 to 1927.

This paper argues that the field of chemistry underwent a significant change of theory in the early twentieth century, when atomic number replaced atomic weight as the principle for ordering and identifying the chemical elements. It is a classic case of a Kuhnian revolution. In the process of addressing anomalies, chemists who were trained to see elements as defined by their atomic weight discovered that their theoretical assumptions were impediments to understanding the chemical world. The only way (...) to normalize the anomalies was to introduce new concepts, and a new conceptual understanding of what it is to be an element. In the process of making these changes, a new scientific lexicon emerged, one that took atomic number to be the defining feature of a chemical element. (shrink)

We provide a detailed history of the concepts of atomic number and isotopy before the discovery of protons and neutrons that draws attention to the role of evolving interplays of multiple aims and criteria in chemical and physical research. Focusing on research by Frederick Soddy and Ernest Rutherford, we show that, in the context of differentiating disciplinary projects, the adoption of a complex and shifting concept of elemental identity and the ordering role of the periodic table led to a (...) relatively coherent notion of atomic number. Subsequent attention to valency, still neglected in the secondary literature, and to nuclear charge led to a decoupling of the concepts of elemental identity and weight and allowed for a coherent concept of isotopy. This concept received motivation from empirical investigations on the decomposition series of radioelements and their unstable chemical identity. A new model of chemical order was the result of an ongoing collaboration between chemical and physical research projects with evolving aims and standards. After key concepts were considered resolved and their territories were clarified, chemistry and physics resumed autonomous projects, yet remained bound by newly accepted explanatory relations. It is an episode of scientific collaboration and partial integration without simple, wholesale gestalt switches or chemical revolutions. (shrink)

Philosophers routinely invoke self‐control in their theorizing, but major questions remain about what exactly self‐control is. I propose a componential account in which an exercise of self‐control is built out of something more fundamental: basic intrapsychic actions called cognitive control actions. Cognitive control regulates simple, brief states called response pulses that operate across diverse psychological systems (think of one's attention being grabbed by a salient object or one's mind being pulled to think about a certain topic). Self‐control ostensibly seems quite (...) different because it regulates complex, temporally extended states such as emotions and cravings. But critically, these complex states also exhibit important componential structure: They rely on response pulses as a key means by which they bring about action. The overall picture is that self‐control consists of skilled sequences of cognitive control directed against extended streams of response pulses that arise from states such as emotions and cravings, thus preventing these states from being effective in action. The account clarifies the “atoms” of self‐control—the elemental units that get combined in complex ways to produce different kinds of self‐control actions. Surprisingly, the account, which is derived from research in cognitive science, aligns nicely with the commonsense conception of self‐control. (shrink)

The prime objective of this study is to discuss the economic impact of the COVID-19 crisis concerning Pakistan and globally across South Asian developing countries. It also demonstrates those economic indicators through which the economic performance of the countries is influenced considering the prospective global economic costs of COVID-19 under different scenarios. The study systematically reviewed the literature on historical pandemic crises and the most recent Covid-19 fallout economic disorder in South Asian countries. Considering the history of human civilization, (...) there are varied instances of severe epidemics that are caused by numerous viruses. It is observed that the prevailing outbreak of COVID-19 has eventually affected large scale manufacturing, service sectors and arose supply side constraint to an extent. On the contrary, GDP and consumption declined sharply. Furthermore, sudden loss of service sector jobs and the rise in food prices have created an economic crisis for developing countries of South Asia. The study attempts to discuss the policy responses given by the World Bank, International Monetary Fund, Asian Development Bank, The State Bank of Pakistan, and the Ministry of finance, Pakistan encountered due to the deteriorating international environment, fiscal stress, and difficulties in financial liquidity markets and provides relevant policies for the better prospect of Pakistan's economy after comparing it with other South Asian countries affected by this pandemic vulnerabilities.

The intention of Atomic Order is to encourage and contribute to the dialogue between philosophers and scientists by discussing a concrete example of scientific discovery according to a method acceptable and understandable to both sides. This discussion takes simultaneously into account the scientific and philosophical methodologies and mentalities. By regarding "pure" science or "pure" philosophy as limiting cases, it becomes evident that basic questions are best posed and answered by emphasiz ing the deeply embedded complementary relationship between the two. (...) The example chosen is atomic physics, and a systematic method is developed to illuminate the philosophical structure of this science--and science generally--from within.The book consists of two parts. The first part is devoted to the problem of atomic order as discovered and verified by physics, from the speculations of Dalton to the consequences of modern quantum mechanics. These chapters will afford a telescopic, historical review to the scientific reader and a reliable, understandable account of the physical discoveries and theories to the nonscientist. The second part analyzes the presuppositions, guiding principles, and implications that made possible the development of atomic physics and that impart a humanistic meaning to it. In separate chapters are discussed the epistemological structure of atomic physics, the new conception of matter implicit in the quantum theory, and the ontological implications of atomic order. It is seen that, in this area, science and philosophy are inextricably interpenetrated. A philosophic problematic is immanent in creative atomic science, as is evidenced by the numerous reflections and speculations of scientists that are quoted in the book. Conversely, an interest in scientific research is indispensable for a modern philosopher, and the philosopher may well be surprised and encouraged on recognizing the role already being played by philosophy in the supposedly pragmatic world of science.Dr. Cantore brings an ecumenical cast Lof mind to the healing of the bjcultural split between the humanists and the scientists. The recipient of a doctorate in physics and another in philosophy, he has drawn from both fields in a book dedicated to "making the educated public more aware of the need and method for a new synthesis between the two cultures.".

In this paper I discuss some consequences and manifestations of a mereology of structured wholes in chemistry, with particular reference to the concept of atoms in molecules.

Research into learners' ideas aboutscience suggests that school and collegestudents often hold alternative conceptionsabout `the atom'. This paper discusses whylearners acquire ideas about atoms which areincompatible with the modern scientificunderstanding. It is suggested that learners'alternative ideas derive – at least in part –from the way ideas about atoms are presented inthe school and college curriculum. Inparticular, it is argued that the atomicconcept met in science education is anincoherent hybrid of historical models, andthat this explains why learners commonlyattribute to atoms properties (...) (such as beingthe constituent particles of all substances, orof being indivisible and conserved inreactions) that more correctly belong to otherentities (such as molecules or sub-atomicparticles). Bachelard suggested that archaicscientific ideas act as `epistemologicalobstacles', and here it is argued thatanachronistic notions of the atom survive inthe chemistry curriculum. These conceptualfossils encourage learners to develop an`atomic ontology' (granting atoms `ontologicalpriority' in the molecular model of matter); tomake the `assumption of initial atomicity' whenconsidering chemical reactions; and to developan explanatory framework to rationalisechemical reactions which is based on thedesirability of full electron shells. Theseideas then act as impediments to thedevelopment of a modern chemical perspective onthe structure of matter, and an appreciation ofthe nature of chemical changes at the molecularlevel. (shrink)

This paper suggests that the cases made for atoms and the aether in nineteenth-century physical science were analogous, with the implication that the case for the atom was less than compelling, since there is no aether. It is argued that atoms did not play a productive role in nineteenth-century chemistry any more than the aether did in physics. Atoms and molecules did eventually find an indispensable home in chemistry but by the time that they did so they were different kinds (...) of entities to those figuring in the speculations of those natural philosophers who were atomists. Advances in nineteenth-century chemistry were a precondition for rather than the result of the productive introduction of atoms into chemistry. (shrink)

In this paper I shall explore a novel alternative to these familiar views. In his recent book Sub ects of Ex erience, E. J. Lowe argues, as many others have done before, that you and I are not animals. It follows from this, he says, that we must be simple substances without parts. That may sound like Cartesian dualism. But Lowe is no Cartesian. He argues from premises that many present-day materialists accept. And he claims that our being mereologically simple (...) is consistent with our having such paradigmatically physical properties as being six feet tall and weighing 160 pounds. You and I, he claims, are mereological atoms shaped like human beings. (shrink)

The concepts of atoms and bonds in molecules which appeared in chemistry during the nineteenth century are unavoidable to explain the structure and the reactivity of the matter at a chemical level of understanding. Although they can be criticized from a strict reductionist point of view, because neither atoms nor bonds are observable in the sense of quantum mechanics, the topological and statistical interpretative approaches of quantum chemistry (quantum theory of atoms in molecules, electron localization function and maximum probability domain) (...) provide consistent definitions which accommodate chemistry and quantum mechanics.

"Atom," "byte" and "gene" are metonymies for techno-scientific developments of the 20th century: nuclear power, computing and genetic engineering. Resistance continues to challenge these developments in public opinion. This book traces historical debates over atoms, bytes and genes which raised controversy with consequences, and argues that public opinion is a factor of the development of modern techno-science. The level and scope of public controversy is an index of resistance, examined here with a "pain analogy" which shows that just as pain (...) impacts movement, resistance impacts techno-scientific mobilization: it signals that something is wrong, and this requires attention, elaboration and a response to the challenge. This analysis shows how different fields of enquiry deal with the resistance of social-psychological mentalities in the face of industrial, scientific and political activities inspired by projected futures.

In this paper I address two important objections to the theory called ‘ Composition as Identity’ : the ‘wall-bricks-and-atoms problem’, and the claim that CAI entails mereological nihilism. I aim to argue that the best version of CAI capable of addressing both problems is the theory I will call ‘Atomic Composition as Identity’ which consists in taking the plural quantifier to range only over proper pluralities of mereological atoms and every non-atomic entity to be identical to the plurality (...) of atoms it fuses. I will proceed in three main steps. First, I will defend Sider’s Composition as identity.

Second, I will argue that CAI-theorists should uphold an ‘atomic comprehension principle’ which, jointly with CAI, entails that there are only proper pluralities of mereological atoms. Finally, I will present a novel reading of the ‘one of’ relation that not only avoids the problems presented by Yi Composition as identity.

: This paper examines the debate in the late 19th and early 20th centuries over the acceptability of atomic and molecular physics. It focuses on three prominent figures: Maxwell, who defended atomic physics, Ostwald, who initially rejected it but changed his mind as a result of experiments by Thomson and Perrin, and Duhem, who never accepted it. Each scientist defended the position he did in the light of strongly held methodological views concerning empirical evidence. The paper critically evaluates (...) each of these methodological positions. (shrink)

A possible atomic mechanism underlying the Re- and Ru-induced strengthening effects on the n - n ' interface in Ni-based single-crystal superalloys has been investigated using the DMol3 molecular orbital package based on density functional theory. The calculation of bonding properties has been performed on a cluster designed to model Re and Ru strengthening effects within the interface. The stronger Re--Ni bonds are formed mainly as a result of d- hybridization, while the Ni--Ni bonding become weaker accompanying the Re (...) substitution. The vertical and horizontal bond orders for a local environmental cluster are proposed and developed for the description of the strengthening effect on the n - n ' interface, with larger bond order values achieving better effect. Results show that both Re and Ru significantly strengthen the interface. It is also shown that the strengthening effect of Re is better than that of Ru, and this is explained in terms of the charge transfer of electrons between orbitals of Ru atom according to Mulliken population analysis. The calculation results provide a basis for understanding the atomic mechanism of Re- and Ru-induced n - n ' interfacial strengthening. (shrink)

Event concepts are unstructured atomic concepts that apply to event types. A paradigm example of such an event type would be that of diaper changing, and so a putative example of an atomic event concept would be DADDY'S-CHANGING-MY-DIAPER.1 I will defend two claims about such concepts. First, the conceptual claim that it is in principle possible to possess a concept such as DADDY'S-CHANGING-MY-DIAPER without possessing the concept DIAPER. Second, the empirical claim that we actually possess such concepts and (...) that they play an important role in our cognitive lives. The argument for the empirical claim has the form of an inference to the best explanation and is aimed at those who are already willing to attribute concepts and beliefs to infants and nonhuman animals. Many animals and prelinguistic infants seem capable of re-identifying event-types in the world, and they seem to store information about things happening at particular times and places. My account offers a plausible model of how such organisms are able to do this without attributing linguistically structured mental states to them. And although language allows adults to form linguistically structured mental representations of the world, there is no good reason to think that such structured representations necessarily replace the unstructured ones. There is also no good reason for a philosopher who is willing to explain the behavior of an organism by appealing to atomic concepts of individuals or kinds to not use a similar form of explanation when explaining the organism's capacity to recognize events. -/- We can form empirical concepts of individuals, kinds, properties, event-types, and states of affairs, among other things, and I assume that such concepts function like what François Recanati calls ‘mental files’ or what Ruth Millikan calls ‘substance concepts’ (Recanati 2012; Millikan 1999, 2000, 2017). To possess such a concept one must have a reliable capacity to re-identify the object in question, but this capacity of re-identification does not fix the reference of the concept. Such concepts allow us to collect and utilize useful information about things that we re-encounter in our environment. We can distinguish between a perception-action system and a perception-belief system, and I will argue that empirical concepts, including atomic event concepts, can play a role in both systems. The perception-action system involves the application of concepts in the service of (often skilled) action. We can think of the concept as a mental file containing motor-plans that can be activated once the individual recognizes that they are in a certain situation. In this way, recognizing something (whether an object or an event) as a token of a type, plays a role in guiding immediate action. The perception-belief system, in contrast, allows for the formation of beliefs that can play a role in deliberation and planning and in the formation of expectations. I distinguish between two particular types of belief which I call where-beliefs and when-beliefs, and I argue that we can model the formation of such perceptual beliefs in nonlinguistic animals and human infants in terms of the formation of a link between an empirical concept and a position on a cognitive map. According to the account offered, seemingly complex beliefs, such as a baby's belief that Daddy changed her diaper in the kitchen earlier, will not be linguistically structured. If we think that prelinguistic infants possess such concepts and are able to form such beliefs, it is likely that adults do too. The ability to form such beliefs does not require the capacity for public language, and we can model them in nonlinguistic terms; thus, we have no good reason to think of such beliefs as propositional attitudes. Of course, we can use sentences to refer to such beliefs, and thus it is possible to think of such beliefs as somehow relations to propositions. But it is not clear to me what is gained by this as we have a perfectly good way to think about the structure of such beliefs that does not involve any appeal to language. (shrink)

In this paper we analyse the approach to interpreting atomic spectra in the framework of classical physics from the discovery of the electron in 1897 to Bohr's atomic model of 1913. Taken as a whole, efforts in this direction are part of a remarkable intellectual endeavour in which the classical theoretical framework seems to have been exploited to its full potential. By demonstrating the limits and weaknesses of classical physics in solving the problem of spectral emissions, these attempts (...) opened the way to a complete break from traditional thought and the introduction of the new quantum ideas.

We give an account of some relationships between the principles of Constant and Atom Exchangeability and various generalizations of the Principle of Instantial Relevance within the framework of Inductive Logic. In particular we demonstrate some surprising and somewhat counterintuitive dependencies of these relationships on ostensibly unimportant parameters, such as the number of predicates in the overlying language.

This article examines the attempt by the Kingdom of Morocco—a country of pivotal geopolitical importance in the late 1970s and early 1980s—to secure a research reactor. It finds that by treating that reactor as a diplomatic object, we can observe the different diplomatic frameworks in which that object was conceived of, contextualized, and negotiated. The historical emergence of these frameworks occurred in close relationship with the IAEA, which acted as an intermediary linking various administrations, programs, and countries, including Morocco. In (...) the end, this history reveals that the late Cold War nuclear world involved multilateral actions and forces, some of which encouraged Morocco in its bid to acquire a reactor, but others of which left that same reactor orphaned and unfinished.

For any finite n 3 there are two atomic n-dimensional cylindric algebras with the same atom structure, with one representable, the other, not.Hence, the complex algebra of the atom structure of a representable atomic cylindric algebra is not always representable, so that the class RCAn of representable n-dimensional cylindric algebras is not closed under completions. Further, it follows by an argument of Venema that RCAn is not axiomatisable by Sahlqvist equations, and hence nor by equations where negation can (...) only occur in constant terms.Similar results hold for relation algebras.

It is customary practice to define ‘x is composed of the ys’ as ‘x is a sum of the ys and the ys are pairwise disjoint ’. This predicate has played a central role in the debate on the special composition question and on related metaphysical issues concerning the mereological structure of objects. In this note we show that the customary characterization is nonetheless inadequate. We do so by constructing a mereological model where everything qualifies as composed of atoms even (...) though some elements in the domain are gunky, i.e., can be divided indefinitely into smaller and smaller proper parts.

For this eighth edition he also wrote a new chapter on the quantum theory of solids.

It has been known for six years that the restriction of Girard's polymorphic system $\text{\bfseries\upshape F}$ to atomic universal instantiations interprets the full fragment of the intuitionistic propositional calculus. We firstly observe that Tait's method of “convertibility” applies quite naturally to the proof of strong normalization of the restricted Girard system. We then show that each $\beta$-reduction step of the full intuitionistic propositional calculus translates into one or more $\beta\eta$-reduction steps in the restricted Girard system. As a consequence, we (...) obtain a novel and perspicuous proof of the strong normalization property for the full intuitionistic propositional calculus. It is noticed that this novel proof bestows a crucial role to $\eta$-conversions. (shrink)
