ABSTRACTThere is a growing body of literature describing conceptual frameworks for working with participatory visual methods. Through a global health lens, this paper examines some key themes within these frameworks. We reflect on our experiences of working with with an array of PVM to engage community members in Vietnam, Kenya, the Philippines and South Africa in biomedical research and public health. The participants that we have engaged in these processes live in under-resourced areas with high prevalence of communicable and non-communicable (...) diseases. Our paper describes some of the challenges that we have encountered while using PVM to foster knowledge exchange, build relationships and facilitate change among individuals and families, community members, health workers, biomedical scientists and researchers. We consider multiple ethical situations that have arisen through our work and discuss the ways in which we have navigated and negotiated them. We offer our reflections and learning from facil...

Death from cancer is usually due to metastasis. Fortunately, most cells that escape from a primary tumor fail to form metastases. Identifying reasons for this failure will help development of anti‐metastatic therapies. Intravital videomicroscopy (IVVM) can be used to observe cancer cells injected into live animals. Co‐injected microspheres can be used to assess cell survival. These techniques have been used to show that circulating tumor cells generally arrest in the microcirculation and may extravasate with high efficiency. While many tumor cells (...) may survive in a secondary site, only a small subset form micrometastases and only a subset of these micrometastases persist to form vascularized macrometastases. Furthermore, solitary tumor cells may remain dormant for long periods of time in secondary sites. These findings suggest that metastatic growth and angiogenesis are prime targets for anti‐metastatic therapy. BioEssays 24:885–893, 2002. © 2002 Wiley Periodicals, Inc. (shrink)

It is an experimental fact that \ -decays produce in a cloud chamber at most one track and that this track points in a random direction. This seems to contradict the description of decay in Quantum Mechanics: according to Gamow a spherical wave is produced and moves radially according to Schrödinger’s equation. It is as if the interaction with the supersaturated vapor turned the wave into a particle. The aim of this note is to place this effect in the context (...) of Schrödinger’s Quantum Mechanics. We shall see that the properties of the initial wave function suggest the introduction of a semiclassical formalism in which the \ -wave can be described as a collection of semiclassical wavelets; each of them interacts with an atom and forms an entangled state. The interaction can be regarded as a semiclassical inelastic scattering event. The measurement selects the wave function of one of the ions, with a probability given by Born’s rule. This ion interacts with the atoms nearby leading to the formation of a droplet. One can reasonably assume that also the wavelet entangled with the selected ion has probability one to remain as part of the description of the system. The measurement process is therefore represented by a unitary operator. The wavelet remains sharply localized on a classical path \ It is still a probability wave: it determines the probability that another atom be ionized. This probability is essentially zero unless the atom lies on \ . This gives the visible track. (shrink)

In a cloud chamber, the quantum measurement problem amounts to explaining the first droplet in a charged-particle track; subsequent droplets are explained by Mott’s 1929 wave-theoretic argument about collision-induced wavefunction collimation. I formulate a mechanism for how the first droplet in a cloud chamber track arises, making no reference to quantum measurement axioms. I look specifically at tracks of charged particles emitted in the simplest slow decays, because I can reason about rather than guess the form that wave packets take. (...) The first visible droplet occurs when a randomly occurring, barely-subcritical vapor droplet is pushed past criticality by ionization triggered by the faint wavefunction of the emitted charged particle. This is possible because potential energy incurred when an ionized vapor molecule polarizes the other molecules in a droplet can balance the excitation energy needed for the emitted charged particle to create the ion in the first place. This degeneracy is a singular condition for Coulombic scattering, leading to infinite or near-infinite ionization cross sections, and from there to an emergent Born rule in position space, but not an operator projection as in the projection postulate. Analogous mechanisms may explain canonical quantum measurement behavior in detectors such as ionization chambers, proportional counters, photomultiplier tubes or bubble chambers. This work is important because attempts to understand canonical quantum measurement behavior and its limitations have become urgent in view of worldwide investment in quantum computing and in searches for super-rare processes.

For many commentators in bioethics and the law, safety is the fulcrum for evaluating the ethics of human reproductive cloning. Carson Strong has argued that if cloning were effective and safe it should be available to married couples who have tried to have children through various assisted reproductive technologies but been unable to do so. On his view, cloning should be available only as reproductive last resort. I challenged that limited use by trying to show that the arguments Strong adduces (...) in favor of reproductive somatic nuclear transfer for married couples extend to same-sex couples as well, who face a different kind of infertility. I also went on to argue that his justifications would in fact extend the legitimate use of SNT to any couples regardless of whether they had fertility difficulties or not. (shrink)

In this paper two models for movement of respiratory gases in the insect trachea are presented. One model considers the tracheal system as a single flexible compartment while the other model considers the trachea as a single flexible compartment with gas exchange. This work represents an extension of Ben-Tal’s work on compartmental gas exchange in human lungs and is applied to the insect tracheal system. The purpose of the work is to study nonlinear phenomena seen in the insect respiratory system. (...) It is assumed that the flow inside the trachea is laminar, and that the air inside the chamber behaves as an ideal gas. Further, with the isothermal assumption, the expressions for the tracheal partial pressures of oxygen and carbon dioxide, rate of volume change, and the rates of change of oxygen concentration and carbon dioxide concentration are derived. The effects of some flow parameters such as diffusion capacities, reaction rates and air concentrations on net flow are studied. Numerical simulations of the tracheal flow characteristics are performed. The models developed provide a mathematical framework to further investigate gas exchange in insects. (shrink)

Purpose This study aims to understand the allure and danger of fake news in social media environments and propose a theoretical model of the phenomenon. Design/methodology/approach This qualitative research study used the uses and gratifications theory approach to analyze how and why people used social media during the 2016 US presidential election. Findings The thematic analysis revealed people were gratified after using social media to connect with friends and family and to gather and share information and after using it as (...) a vehicle of expression. Participants found a significant number of fake news stories on social media during the 2016 US presidential election. Participants tried to differentiate between fake news and real news using fact-checking websites and news sources and interacted with the social media users who posted fake news and became part of the echo chamber. Behaviors like these emerged in the analysis that could not be completely explained by UGT and required further exploration which resulted in a model that became the core of this study. Research limitations/implications This is a small-scale exploratory study with eight diverse participants, findings should not be generalized to larger populations. Time-specific self-reporting of information from social media and fake news during the 2016 US presidential election. Upgrading public policies related to social media is recommended in the study, contributing to burgeoning policy discussions and provides recommendations for both purveyors of social media and public policymakers. Practical implications Upgrade in public policies related to social media is recommended in the study and contributes to burgeoning policy discussions and provides recommendations for both purveyors of social media and public policymakers. Social implications Social media users are spending increased time on their preferred platforms. This study increases the understanding of the nature, function and transformation of virtual social media environments and their effects on real individuals, cultures and societies.What is original/of value about the paper?This exploratory study establishes the foundation on which to expand research in the area of social media use and fake news. Originality/value This exploratory study establishes the foundation to expand research in the area of social media use and fake news. (shrink)

Palace of the End is a dense triptych of monologues exploring alternative narratives - albeit based in real facts - behind the events and the headlines surrounding the war in Iraq. Borrowing its title from the former royal palace where Saddam Hussein’s torture chamber was located, Thompson’s docudrama is structured as a chain of monologues telling three real-life stories set in the context of the war in Iraq. The play conveys three unconventional interpretations of the realities of war: that of (...) a young American soldier convicted for her misconduct at Abu Ghraib, the prison that stands as one of the most controversial symbols of the American-led Iraq invasion; a British scientist and weapons inspector who denounces what he understands as the false arguments given by his country’s leaders for engaging in a distant war; and an Iraqi mother whose life was shattered firstly by Saddam Hussein’s authoritarian regime, and later by the American first Gulf War. Each story is an enthralling and gut-wrenching reflection of one of the contemporary world’s most studied and controversial conflicts. The play gives voice to three different kinds of war victims, insofar as their political subjectivities and their moral conundrums are concerned. (shrink)

Jean E. Chambers and Timothy F. Murphy responded to my article “Cloning and Infertility” and extended the debate over human cloning in interesting ways. I had argued that none of the objections to cloning by somatic cell nuclear transfer are successful in the context of infertile couples who use cloning to have genetically related children, assuming the issue of safety is overcome by scientific advances.

This paper offers an account of collective epistemic vices, which we call the “group identification account”. The group identification account attributes collective epistemic vices to the groups that are constituted by “group identification”, which is a primitive and non-doxastic self-understanding as a group member (Turner, 1982; Brewer, 1991; Brewer & Gardner, 1996; Pacherie, 2013; Salice & Miyazono, 2020). The distinctive feature of the group identification account is that it enables us to attribute epistemic vices not just to established social groups (...) (e.g. committees, research teams, juries) but also to loose social groups (e.g. loosely connected people in an echo chamber) when they are constituted by group identification. The group identification account is contrasted with Fricker’s (2010, 2020) influential account, the “joint commitment account”, which focuses on established social groups, and has difficulty in making sense of collective epistemic vices of loose social groups. The group identification account is motivated by the fact that collective epistemic vices can be useful to diagnose not only the epistemic performance of established groups but also that of loose groups in real-life cases, such as echo chamber (Nguyen, 2020), implicit bias (Holroyd, 2020), group polarization (Broncano-Berrocal & Carter, 2021), etc. (shrink)

The war on terrorism, say America's leaders, is a war of Good versus Evil. But in the minds of the perpetrators, the September 11 attacks on New York and Washington were presumably justified as ethically good acts against American evil. Is such polarization leading to a violent "clash of civilizations" or can differences between ethical systems be reconciled through rational dialogue? This book provides an extraordinary resource for thinking clearly about the diverse ways in which humans see good and evil. (...) In nine essays and responses, leading thinkers ask how ethical pluralism can be understood by classical liberalism, liberal-egalitarianism, critical theory, feminism, natural law, Confucianism, Islam, Judaism, and Christianity. Each essay addresses five questions: Is the ideal society ethically uniform or diverse? Should the state protect, ban, or otherwise intervene in ethically based differences? How should disagreements on the rights and duties of citizens be dealt with? Should the state regulate life-and-death decisions such as euthanasia? To what extent should conflicting views on sexual relationships be accommodated? This book shows that contentious questions can be discussed with both incisiveness and civility.

Hayek's substantial contribution to theoretical psychology has been addressed in the work of Thomas Szasz, Gerald Edelman, and Joaquin Fuster.

Following her abdication, Queen Christina of Sweden took up residence in the Palazzo Farnese, Rome from 1655. She had already developed a keen interest in music, gained from tuition from a French dancing master, and playing the star role in the ballet The Captured Cupid in honour of her mother's birthday in 1649. Christina's arrival in Rome was marked by performances in her honour in the Palazzo Barberini and Palazzo Pamphili of specially commissioned works by contemporary composers Marco Marazzoli and (...) A.F. Tenaglia, and by her favourite Giacomo Carissimi. Inspired by the chamber music proportions of the cappella of the Collegio Germanico, many of Carissimi's secular arias were composed for his royal Swedish patron. After two years in France, Christina returned to Rome, where she took up residence in the Palazzo Riario on the Janiculum. Inventories record her musical instruments and describe the contents of the Great Hall in which concerts were held. (shrink)

With a new foreword by Paul Kelly 'I regard Hayek's work as a new opening of the most fundamental debate in the field of political philosophy' - Sir Karl Popper 'This promises to be the crowning work of a scholar who has devoted a lifetime to thinking about society and its values. The entire work must surely amount to an immense contribution to social and legal philosophy' - Philosophical Studies Law, Legislation and Liberty is Hayek's major statement of political philosophy (...) and one of the most ambitious yet subtle defences of a free market society ever written. A robust defence of individual liberty, it is also crucial for understanding Hayek's influential views concerning the role of the state: far from being an innocent bystander, he argues that the state has an important role to play in defending the norms and practices of an ordered and free society. His arguments had a profound influence on the policies of Thatcher in the 1980s and resonate today in visions of the 'Big Society'. First published in three separate volumes, this Routledge Classics edition makes one of his most important books available in a single volume. Essential reading for understanding the background to the recent world economic turmoil and financial crisis, it also foreshadows the subsequent heated debate about regulation and political governance if such disasters are to be avoided in the future.

This essay examines the relationship between the novelist/philosopher Ayn Rand (TheFountainhead,AtlasShrugged) and the broader conservative movement in the twentieth-century United States. Although Rand was often dismissed as a lightweight popularizer, her works of radical individualism advanced bold arguments about the moral status of capitalism, and thus touched upon a core issue of conservative identity. Because Rand represented such a forthright pro-capitalist position, her career highlights the shifting fortunes of capitalism on the right. In the 1940s, she was an inspiration to (...) those who struggled against the New Deal and hoped to bring about a new, market-friendly political order. As a second generation of conservatives built upon these sentiments and attempted to tie them to a defense of Christian tradition, Rand's status began to erode. Yet by the late 1960s, Rand's once-revolutionary defense of capitalism had become routine, although she herself remained a controversial figure. The essay traces the ways in which Rand's ideas were assimilated and modified by key intellectuals on the right, including William F. Buckley, Jr, Whittaker Chambers, and Gary Wills. It identifies the relationship between capitalism and Christianity as a fundamental dilemma for conservative and right-wing thinkers. By treating Rand as an intellectual and cultural leader of significant import, the essay broadens our understanding of the American right beyond the confines of conservatism, and re-establishes the primacy of the 1930s, and 1940s, to its ideological formation. Responding to a paucity of scholarship on Rand, the essay offers an analysis and summary of Rand's ideas, and argues that despite her outsider status, Rand's work both embodied and shaped fundamental themes of right-wing thought throughout the century.

The growing prominence of computers in contemporary life, often seemingly with minds of their own, invites rethinking the question of moral responsibility. If the moral responsibility for an act lies with the subject that carried it out, it follows that different concepts of the subject generate different views of moral responsibility. Some recent theorists have argued that actions are produced by composite, fluid subjects understood as extended agencies (cyborgs, actor networks). This view of the subject contrasts with methodological individualism: the (...) idea that actions are produced only by human individuals. This essay compares two views of responsibility: moral individualism (the ethical twin of methodological individualism), and joint responsibility (associated with extended agency theory). It develops a view of what joint responsibility might look like, and considers the advantages it might bring relative to moral individualism as well as the objections that are sure to be raised against it.

RésuméCet article a été inspiré par l'opposition qui semble exister entre les deux grands courants animant l'œuvre de M. Bachelard.Les auteurs rappellent la différence existant entre une organisation predicative et une organisation dialectique de la connaissance. La connaissance objective est de structure dialectique. Il en résulte que l'évolution de cette connaissance s'accompagne d'un processus obligé de dévalorisation et de revalorisation relative de ses formes antérieures.Ce même processus rend aussi compte des rapports de la pensée poétique et de la pensée objective (...) et scientifique.Dans cette perspective, l'unité d'inspiration de l'œuvre de M. Bachelard est parfaitement évidente. — F. et J.‐P. G. (shrink)
