A gedanken experiment that distinguishes locally between acceleration of rotation and linear acceleration is described and discussed.

A rotating disk with angular acceleration is given a relativistic description as observed from the rotating rest frameR of the disk. It is shown how a non-Euclidean intrinsic spatial geometry develops inR, as the disk gets an angular velocity. The explanation of this as given by anR-observer is discussed. A recent description of the geometry inR presented by Grünbaum and Janis is criticized. The motion of light as described by use of coordinate clocks inR is discussed in connection (...) with some recent work by R. C. Jennison and coworkers. The significance of the difference between directed signals and circular waves when clocks inR are to be synchronized by means of light emitted from the axis inR is made clear. (shrink)

Alternative theories of relativistic rotation considered viable as of 2004 are compared in the light of experiments reported in 2005. En route, the contentious issue of simultaneity choice in rotation is resolved by showing that only one simultaneity choice, the one possessing continuous time, gives rise, via the general relativistic equation of motion, to the correct Newtonian limit Coriolis acceleration. In addition, the widely dispersed argument purporting Lorentz contraction in rotation and the concomitant curved surface (...) of a rotating disk is analyzed and argued to be lacking for more than one reason. It is posited that not by theoretical arguments, but only via experiment can we know whether such effect exists in rotation or not. The Coriolis/simultaneity correlation, and the results of the 2005 experiments, support the Selleri theory as being closest to the truth, though it is incomplete in a more general applicability sense, because it does not provide a global metric. Two alternatives, a modified Klauber approach and a Selleri–Klauber hybrid, are presented which are consistent with recent experiment and have a global metric, thereby making them applicable to rotation problems of all types.

The subject matter of the article is a standard cosmological model of the Universe. Contemporary opinion regarding origin, structure, and evolution of the Universe is of great interest. The answer to the question of the Universe origin is given by the Big Bang Theory. Is it possible to be sure in this theory correctness, which persuading of the Universe origination from the singularity fluctuation, when the World had appeared from nowhere, that is from abstract nothingness, further accelerated expansion of the (...) Universe following the Big Bang, and its development up to present with inexplicable source of energy for that. However, in the extreme end of the meta-universe the speed of stellar formations runaway is about the light velocity. Further, there is a new problem, the finiteness of the Universe. There are two counter-opinions, if the expanding Universe is finite or infinite. A very important question arises here, the question regarding isolatedness of the Universe as a system. The problem of the Universe heat death is closely connected with it. For this reason it is the time to discuss the Universe entropy. There is a short description of notions and problems with reference to this branch of knowledge, as well as of Doppler and Ritz effects alongside with Habble Law. The authors’ detailed interpretation of an entropy is also suggested. The analysis of the existing model is followed by the idea of the authors about the Universe organization. The style of the article is popular-science. In the first part of the article the existing concept of the Expanding Universe Theory and the dynamical Friedmann-Lemaitre models are described; it deals with the existing concept of the Big Bang Theory as well as the dark energy and the dark matter notions. In the second part the author gives detailed interpretation of an entropy. In the last part the problem of theoretical basis and fact nonconformity within the Expanding Universe Model Theory and the authors’ idea about the Universe organization are considered. (shrink)

The aesthetics of everyday life, originally developed by Henri Lefebvre and other modernist theorists, is an extension of traditional aesthetics, usually confined to works of art. It is not limited to the study of humble objects but is rather concerned with all of the undeniably aesthetic experiences that arise when one contemplates objects or performs acts that are outside the traditional realm of aesthetics. It is concerned with the nature of the relationship between subject and object. One significant aspect of (...) everyday aesthetics is environmental aesthetics, whether constructed, as a building, or manipulated, as a landscape. Others, also discussed in the book, include sport, weather, smell and taste, and food. (shrink)

If is often taken for granted that on a rotating disk it is possible to operate a global 3+1 splitting of spacetime such that both lengths and time intervals are uniquely defined in terms of measurements performed by real rods and real clocks at rest on the platform. This paper shows that this assumption, although widespread and apparently trivial, leads to an anisotropy of the velocity of two light beams traveling in opposite directions along the rim of the disk, (...) which in turn implies some recently pointed out paradoxical consequences undermining the self-consistency of the special theory of relativity (SRT). A correct application of the SRT solves the problem and recovers complete internal consistency for the theory. As an immediate consequence, it is shown that the Sagnac effect only depends on the nonhomogeneity of time of the platform and has nothing to do with any anisotropy of the speed of light along the rim of the disk, contrary to an incorrect but widely held idea.

Institutional corruption is a normative concept of growing importance that embodies the systemic dependencies and informal practices that distort an institution’s societal mission. An extensive range of studies and lawsuits already documents strategies by which pharmaceutical companies hide, ignore, or misrepresent evidence about new drugs; distort the medical literature; and misrepresent products to prescribing physicians. We focus on the consequences for patients: millions of adverse reactions. After defining institutional corruption, we focus on evidence that it lies behind the epidemic of (...) harms and the paucity of benefits. (shrink)

Some terms identify enigmata of today’s cosmology: “Inflation” is expected to explain the homogeneity and isotropy of the cosmic background. The repulsive force of a “dark energy” shall prevent a re-collapse of the cosmos. The additional gravitational effect of a “dark matter” was originally supposed to explain the deviations of the rotation curves of the galaxies from Kepler’s laws. Adopting a theory founded on the core notion of absolute quantum information–Protyposis–being a cosmological concept from the outset, the observed phenomena (...) can be explained without postulating further unknown specific “particles” or “fields”. Moreover, this theory allows for a rationalization of the fact that huge black holes with their enormous jet structures, acting as “seeds” of the galaxies, are detected ever closer to the big bang. The problem of the rotation curves in the galaxies can be addressed outside of General Relativity within a Newtonian approximation: by an attenuation of the gravitational acceleration as in the modified Newtonian dynamics, or by the effect of additional invisible “particles of dark matter”, yet unknown and not yet established in natural sciences. Within the Protyposis theory, these problems are solved without having to invent a lot of parameters. The cosmology of the Protyposis causes the change of the gravitational acceleration in the vicinity of large masses and, at the same time, avoids a recollapse of the cosmos for which a cosmological constant or “dark energy” was invented.

Discussion of ecological restoration in environmental ethics has tended to center on issues about the nature and character of the values that may or may not be produced by restored landscapes. In this paper we shift the philosophical discussion to another set of issues: the social and political context in which restorations are performed. We offer first an evaluation of the political issues in the practice of restoration in general and second an assessment of the political context into which restoration (...) is moving. The former focuses on the inherent participatory capacity at the heart of restoration; the latter is concerned with the commodified (primarily in the United States) and nationalized (primarily in Canada) uses to which restoration is being put. By comparing these two areas of inquiry we provide a foundation for a critical assessment of the politics of restoration based on the politics in restoration. (shrink)

Newtonian physics is based on Newtonian calculus applied to Newtonian dynamics. New paradigms such as ‘modified Newtonian dynamics’ change the dynamics, but do not alter the calculus.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.1 (2002) 102-108 [Access article in PDF] Symposium IntroductionEric Katz's Nature As Subject Andrew Light Can and should we distinguish between nature and culture? The question has become a perennial one in environmental ethics, as well as in allied fields in environmental history, sociology, and politics. And just when we think it is settled—as many did after William Cronon's famous deconstruction of wilderness in (...) 1995—and it feels safe to go back into the metaphysical waters of environmental philosophy, such issues pop up again to send us running.What follows extends this debate in the context of Eric Katz's well-known work in environmental ethics. Brought together here are Katz and two critics sympathetic to his positions, Wayne Ouderkirk and Ned Hettinger. While the occasion for the exchange was the publication of Katz's book, Nature as Subject: Human Obligation and Natural Community (1997), which collects his papers from 1979 to 1996, the focus quickly became somewhat narrower, centering on possible problems with Katz's ontological dualism between natural and artifactual entities.Katz has exerted a strong influence on the development of environmental ethics, particularly through his persistent arguments for a distinction between individualist and holist approaches to obligations to the nonhuman natural world and his metaphysical and moral critique of attempts [End Page 102] by humans to create, repair, or restore nature. While these positions continue to be on display here, there is also something more. In this exchange Katz throws down the gauntlet on his nature-culture dualism, admitting at the start that the accusation is true. Like the Protestants in Monty Python's The Meaning of Life, he is a dualist—and fiercely proud of it! Despite whatever misgivings I or others may have about this position, I believe that in making this claim, Katz, similar to David Chalmers's open embrace and resuscitation of dualism in philosophy of mind, has done us a great service. For it is arguably true that many environmental philosophers, along with other academics, have settled into a complacent "labeling as argument" pattern. If we can label a position as "dualist" or "essentialist," then our work is done. But surely not every form of dualism is necessarily wrong, even if, as Ouderkirk reminds us in his reading of Val Plumwood's work, the logic of many forms of dualism has tended toward a pernicious pattern. Arguments are needed in both directions. If nature-culture dualism is mistaken or wrongheaded, or leads to unfortunate conclusions, then we must know why; if dualism is the only way to make sense of the hurdles presented to us in coming to a better understanding of the value of nature and culture then we must know why as well. And further, because many in the field have assumed a nature-culture dualism without admitting to it, we can admire that Katz chooses to "fess up" and finally put the issue squarely on the table.If this is the road we are heading down with this particular exchange, then we are off to a good start. Both critics of Katz do a thorough job of pressing home their arguments, rather than only pointing accusatory fingers. Ned Hettinger, in "The Problem of Finding a Positive Role for Humans in the Natural World," avoids using the term "dualism," but nonetheless argues that Katz has a tendency to "rigidly dichotomize the natural/artifactual distinction." Additionally, Hettinger argues that Katz tends to overlook his own admission that the differences between nature and artifacts admit to degrees rather than a strict dualism. Hettinger focuses the bulk of his critique on the unfortunate upshot of such a position: given such a distinction, there is little if any place for a positive role for human intervention in nature, or for a philosophical contribution to the formation of better environmental policies.Wayne Ouderkirk, in "Katz's Problematic Dualism and its 'Seismic' Effects on His Theory," is sympathetic with Katz's intuitions that some distinction is needed between artifacts and natural entities.

As of January 1, 2008, over 98,000 people are waiting for organ transplants in the United States of America. Of those, nearly 75,000 are waiting for a kidney. In this calendar year, fewer than 15,000 will receive a kidney transplant from a deceased donor. The average waiting time for a deceased donor kidney now exceeds five years in virtually all metropolitan areas. Sadly, nearly as many people die waiting as there are deceased donors each year, despite monumental efforts by the (...) entire transplant community to increase both the number of organ donors and the number of organs recovered from each donor. The imbalance between demand and supply has led to considerable efforts to expand the criteria for what is considered an acceptable organ donor by the Organ Procurement and Transplant Network, thereby hoping somewhat to assuage the shortfall of donor organs. So-called Expanded Criteria Donors may be older than 50, have history of hypertension, or have died from intracerebral hemorrhage and/or have impaired renal function. ECDs now make up nearly 40% of the donor population. (shrink)

Can we use technology in the pursuit of a good life, or are we doomed to having our lives organized and our priorities set by the demands of machines and systems?

Contributors both sympathetic and critical examine Borgmann's work, especially his "device paradigm" apply his theories to new areas such as film, agriculture, design, and ecological restoration and consider the place of his thought within philosophy and technology studies more generally. Because this collection carefully investigates the issues at the heart of how we can take charge of life with technology, it will be a landmark work not just for philosophers of technology but for students and scholars in the many disciplines concerned with science and technology studies.

J. Baird Callicott has thrown down the gauntlet once again in the monism?pluralism debate in environmental ethics. In a recent article he argues that his ?communitarianism? (combined with a limited intertheoretic pluralism) is sufficient to get the advantages of pluralism advocated by his critics, while at the same time retaining the framework of moral monism. Callicott's attempt to set the record straight on the monism?pluralism debate has once again derailed us from answering the most important question in this discussion: how (...) do we achieve a compatibilism among ethical theories which will inform better environmental practices? But if Callicott got it wrong, then who is getting it right? Arne Naess, whose work has heretofore been excluded from the mainstream discussion of this issue, has all along understood the heart of the monism?pluralism question. This paper updates the current state of the monism?pluralism debate, provides an answer to Callicott's latest challenge, and advances the thesis that all involved in this argument would do well to take a look at what Naess has to say on this issue.

Empathy is the combined ability to interpret the emotional states of others and experience resultant, related emotions. The relation between prefrontal electroencephalographic asymmetry and emotion in children is well known. The association between positive emotion (assessed via parent report), empathy (measured via observation), and second-by-second brain electrical activity (recorded during a pleasurable task) was investigated using a sample of one hundred twenty-eight 6- to 10-year-old children. Contentment related to increasing left frontopolar activation (p < .05). Empathic concern and positive empathy (...) related to increasing right frontopolar activation (ps < .05). A second form of positive empathy related to increasing left dorsolateral activation (p < .05). This suggests that positive affect and (negative and positive) empathy both relate to changes in prefrontal activity during a pleasurable task. (shrink)

I examine a puzzle concerning the role of humans in the appreciation of place that arises in Christoph Rehmann-Sutter's paper in this volume, specifically the problem of the irreplaceability of place. If places are designated as valuable in part because they are irreplaceable, and if any human can appreciate any place, then how can humans ever be part of a place if they are ultimately substitutable as agents who appreciate places? After identifying the puzzle I briefly discuss two possible ways (...) to answer this problem though the literature on bioregionalism. Two kinds of bioregionalism, liberal bioregionalism (LB) and communitarian bioregionalism (CB) are identified and distinguished. A brief appeal is made to embrace LB for now (which entails avoiding the irreplaceability problem by jettisoning the need to focus on the special qualities of a particular place) and to hold off on CB as a goal down the road which would re-establish the importance of specificity in the value of place.

Robert Elliot's 1982 “Faking Nature,” represents one of the strongest philosophical rejections of the ground of restoration ecology ever offered.1 Here, and in a succession of papers defending the original essay, Elliot argued that ecological restoration, the practice of restoring damaged ecosystems, was akin to art forgery. Just as a copied art work could not reproduce the value of the original, restored nature could not reproduce the value of original nature, conceived as a form of nonanthropocentric and intrinsic, as opposed (...) to merely instrumental, value.2 Eric Katz's 1992 “The Big Lie: Human Restoration of Nature,” extended this claim by further arguing that whatever was produced in a restored landscape it certainly could not count as having the original value of nature, particularly wild nature, and necessarily represented a form of disvalue and domination of nature.3 Elliot has continued to press his argument forward since the original publication of “Faking Nature,” augmenting and some would say softening his critique of restoration, in a book also called Faking Nature.4 Perhaps because both Elliot and Katz rest their claims on the defense of a strong nature-culture distinction, the two arguments are often lumped together as the Elliot-Katz rejection of the value of ecological restoration. Nonetheless, Elliot has made it clear in his recent book that his view is distinct from and even at odds with Katz’s views. In previous papers I have criticized Elliot and Katz’s work as an unhelpful philosophical contribution to the literature on restoration ecology. To my mind, restorationists are ultimately up to more good than harm, and whatever the.. (shrink)

In recent centuries Christians of various denominations have endorsed many different political philosophies that they see as being truly biblical in their approach. Over this time there has been an increasing hostility, by some Christians, towards free markets and political philosophies that hold human liberty as the highest goal such as libertarianism and classical liberalism. This criticism is unwarranted and misplaced as libertarianism and free markets are not only compatible with Christianity, they are also the most biblically sound of all (...) economics systems and political philosophies endorsed by Christians today. Therefore, this paper will argue that Christians of all denominations should endorse free markets and libertarianism if they wish to create a world that follows biblical principles and the teachings of Jesus.

Ned Hettinger, in "The Problem of Finding a Positive Role for Humans in the Natural World," avoids using the term "dualism," but nonetheless argues that Katz has a tendency to "rigidly dichotomize the natural/artifactual distinction." Additionally, Hettinger argues that Katz tends to overlook his own admission that the differences between nature and artifacts admit to degrees rather than a strict dualism. Hettinger focuses the bulk of his critique on the unfortunate upshot of such a position: given such a distinction, there is little if any place for a positive role for human intervention in nature, or for a philosophical contribution to the formation of better environmental policies.Wayne Ouderkirk, in "Katz's Problematic Dualism and its 'Seismic' Effects on His Theory," is sympathetic with Katz's intuitions that some distinction is needed between artifacts and natural entities. The problem [End Page 103] he sees is that such... (shrink)

How do we ready ourselves to intervene responsively in the contingent situations that arise in co-designing to make change? How do we attune to group dynamics and respond ethically to unpredictable developments when working with 'community'? Participatory Design can contribute to social transitions, yet its focus is often tightly tuned to technique for designing ICT at the cost of participatory practice. We challenge PD conventions by addressing what happens as we step into a situation to alter it with others, an (...) aspect of practice that cannot be replicated or interchanged. We do so to argue that practices of readiness are constituted by personal histories, experiences, philosophies and culture. We demonstrate this political argument by giving reflexive accounts of our dimensions of preparation. The narratives here are distinct, yet reveal complementary theories and worldviews that shape PD ontologies. We have organized these around the qualities of punctuation and poise as a way to draw out some less easily articulated aspects of PD practice. (shrink)

T. C. Boyle’s A Friend of the Earth (2001), tells the story of Tyrone Tierwater, a one time monkeywrencher and environmental avenger for “E. F.!” (Earth Forever!) who we first meet in 2025 in his mid-seventies. Tierwater is now working for a character based on Michael Jackson, who in his semi-retirement has employed the elder eco-warrior to help save some of the last remnants of a few dying species – warthogs, peccaries, hyenas, jackals, lions and what is likely the last (...) Patagoninan fox. The not too distant environmental future painted by Boyle is a disaster. Global warming has finally caught up to us with a vengeance and even the secure shores of the U.S. are wracked by unmitigated cycles of flooding and drought seriously degrading most semblances of life as we know it. To be sure, though, people, and some versions of progress, go on. While most affordable food and drink is limited to some combination of catfish and sake (very little else having survived decades of disastrous weather and a series of crop blights), and there are constant threats of new strains of life-threatening and highly contagious diseases, suburban development continues and new humans come into existence with the promise, at least in the developed world, of longer life spans. But Boyle does not give us anything like the overly optimistic views expressed by some conservative columnists who dismiss the need for global climate treaties; this is not an environmental future that is only felt with difficulty in the underdeveloped south requiring simpler economic readjustments for Americans without a substantial shift in lifestyle. The world.. (shrink)

In the typical single-stimulus perceptual identification task, accuracy is improved by prior study of test words, a repetition priming benefit. There is also a cost, inasmuch as previously studied words are likely to be produced as responses if the test word is orthographically similar but not identical to a studied word. In two-alternative forced-choice perceptual identification, a test word is flashed and followed by two alternatives, one of which is the correct response. When the two alternatives are orthographically similar, test (...) words identical to previously studied items are identified more accurately than new words but tests words orthographically similar to studied words are identified less accurately than new words . Ratcliff and McKoon argue that these are bias effects that arise in the decision stage of word identification. We report five experiments that examined the alternative hypothesis that these bias effects arise from postperceptual guessing strategies. In single-stimulus perceptual identification, repetition priming benefits were equally great for young and older adults who claimed to use deliberate guessing strategies and those who did not . In contrast, only groups of young and older people who claimed to deliberately guess studied words in a two-alternative forced-choice task showed reliable benefits and costs. Costs and benefits were abolished in the two-alternative forced-choice task when a very long study list was used, presumably because the increased retrieval burden made the use of deliberate guessing strategies less attractive . Under conditions similar to those of Experiment 3, repetition priming was observed in single-stimulus perceptual identification . These results are consistent with the view that costs and benefits in the forced-choice perceptual identification task arise from deliberate guessing strategies but that those in the single-stimulus task do not. The possibility that the observed relationship between strategy reports and priming effects reflects erroneous postexperimental assessments of strategies by participants is also considered. (shrink)

This chapter discusses the methods of studying the nature of time, particularly the story method. It presents a discussion of time as related to identity and tells the story of a person put on trial for committing a murder five years ago who puts forward an unorthodox defense. The accused person claims to remember committing the murder, but argues that “the murderer is not the same person as me, for I have changed. I am not the same person as that (...) murderer of five years ago. Therefore you cannot punish me, for no one is guilty of a crime committed by someone else.” This defense, though not accepted by the court, raises the question of whether a person who changes over time, either physically or psychologically, remains the same person.

The collection of papers that comprise this thesis explore three sets of questions important to environmental philosophy, broadly construed. All three topics are explored through the theoretical device of environmental pragmatism, the argument that philosophical disagreements on environmental questions can sometimes be set aside in order to achieve compatible strategies to work toward improving environmental conditions. As part of this strategy, pragmatists also call for the abandonment of the existing prejudices of environmental philosophy, in particular nonanthropocentrism and commitments to moral (...) monism. Part I of the thesis looks at two sets of debates in environmental philosophy: the social ecology-deep ecology divide in political ecology, and the debate between monists and pluralists in environmental ethics. Both debates are used as a vehicle to advance the pragmatist position, as well as demonstrate the connection between this thesis and other attempts to articulate a workable form of pluralism in environmental philosophy. Next, the first half of Part II uses the pragmatist premise to launch applied investigations of two environmental questions: the privatization of environmental regulations, and the political appropriation of restoration ecology. The second half of Part II explores questions concerning urban space and political identity, which come to the center of environmental philosophy following a pragmatist assault on its existing prejudices. Finally, Part III continues the themes of the last half of Part II to look at issues concerning technology and built space, topics which have traditionally been ignored by environmental philosophers. These final chapters present a set of issues concerning space and place which must be integral to an environmental philosophy which has been tempered by pragmatic concerns. (shrink)

Foremost in importance among these changes has been a transition in many governments' attitudes to fulfilling their role as caretaker of environmental quality. A question remains, however, concerning the propriety of managing a publicly provided good, such as the regulation of water and air quality, through market mechanisms such as optimal taxes and transferable quotas. There are a number of options open to us if we wish to object to the privatization of the regulation of environmental quality from an ethical (...) perspective. This chapter suggests that the shift to privatization of environmental regulation can be challenged closer to its own economic ground, a move considered somewhat unusual by many environmental ethicists. It argues that inside the economic definition of a "pure public good" resources already exist for challenging the privatization of environmental regulation. Publicly provided goods are goods that may not be traded as commodities, as determined by a public policy. (shrink)

During a transverse acceleration of a light clock from rest, the mirrors must be tilted so as to retain the light pulse. The mirrors therefore have a normal velocity which increases the frequency of the pulse at each reflection. If a mirror is annihilated, the frequency of the escaping pulse, as a result of many reflections, is that of the relativistic Doppler effect. This holds for any acceleration, if the Fitzgerald contraction is assumed, thereby furnishing a (...) new mechanism for such frequencies. The traditional mechanism, in which the source (subject to the time dilation) generates a pulse modulated by the source motion, is therefore not a unique explanation of the Doppler effect. The new mechanism permits the speculation that radiation preexists in atomic sources, rather than being generated at the instant of release. (shrink)

Anthropogenic climate change poses a direct and imminent threat to the stability of modern society. Recent reports of the probable consequences of climate change paint a grim picture; they describe a world environmentally much less stable than the world to which we have become accustomed. As we begin to adapt to our changing climate, we will need to identify new sources for the stability necessary for a flourishing society. I suggest that this stability should come from the ideals of the (...) good life we seek to promote when we focus on capabilities, on the substantial freedoms humans need to flourish. These ideals serve as a stable foundation for well-being in a time of great environmental and social instability; they should serve as guides for our policies, practices and institutions. I conclude by appealing to capabilities as a means of integrating well-being into our adaptation strategies, and show how doing so may well provide a way of formulating a powerful moral justification for adaptation strategies appropriate for both the developed and the developing world.

Biobanks are increasingly being linked together into global networks in order to maximise their capacity to identify causes of and treatments for disease. While there is great optimism about the potential of these biobank networks to contribute to personalised and data-driven medicine, there are also ethical concerns about, among other things, risks to personal privacy and exploitation of vulnerable populations. Concepts drawn from theories of globalisation can assist with the characterisation of the ethical implications of biobank networking across borders, which (...) can, in turn, inform more ethically sophisticated responses. Using the China Kadoorie Biobank as a case study, we show how distinguishing between the subnational, transnational, supranational and extranational spheres of operation and influence can help researchers, institutions and regulators to understand and manage the ethical issues raised by the globalisation of biobanking.

In a new and important book entitled TheManagedCareBluesandHowtoCureThem, a lifetime consumer advocate and a surgeon who witnessed the excesses and unaccountable errors of his colleagues under fee for service explain with deft hands the promise of managed care, its problems, and solutions to them. Walter Zelman and Robert Berenson show empathy for the consumer backlash, provider resentment, and the patients' rights movement that has spawned a thousand bills to prevent possibly unethical actions. Yet they believe these efforts to regulate managed (...) care are misdirected and will prevent it from realizing its potential. (shrink)

This paper gives two complete and elementary proofs that if the speed of light over closed paths has a universal value c, then it is possible to synchronize clocks in such a way that the one-way speed of light is c. The first proof is an elementary version of a recent proof. The second provides high precision experimental evidence that it is possible to synchronize clocks in such a way that the one-way speed of light has a (...) universal value. We also discuss an old incomplete proof by Weyl which is important from an historical perspective. (shrink)

We describe the case of an eighty‐four‐year‐old man with disseminated lung cancer who had been receiving palliative care in the hospital and was found by nursing staff unresponsive, with clinically obvious signs of death, including rigor mortis. Because there was no documentation to the contrary, the nurses commenced cardiopulmonary resuscitation and called a code blue, resulting in resuscitative efforts that continued for around twenty minutes. In discussion with the hospital ethicist, senior nurses justified these actions, mainly citing disciplinary and medicolegal (...) concerns. We argue that moral harms arise from CPR performed on a corpse and that legal concerns about failing to perform it are unfounded. We contend that such efforts are an unintended consequence of managerialist policies mandating do‐not‐resuscitate orders and advance care plans and of defensive practices that can value the interests of institutions and practitioners over those of patients. Health management teaching should include managerialism and its pitfalls, while clinician training should prioritize ethical reasoning and legal knowledge over defensive practice. (shrink)

I. C. Jarvie interprets Popper's philosophy of science as a theory of the institution of science, explains how the social aspect of his theory developed, and suggests that an updated version of Popper's social theory should be used to study both scientific and nonscientific societies today. Although (1) Jarvie's description of the emergence of Popper's theory suffers because he takes no account Popper's research conducted before Logik der Forschung (1994), (2) his portrayal of Popper's framework overlooks important problems, and (3) (...) his program is by no means new, his essay throws light on the relation between Popper's philosophy of science, his social theory, and his social studies of science.

The convergence of biomedical and information technology holds the potential to alter the discourses of identity, or as is argued here, to turn us inside out. The advent of digital networks makes it possible to ‘see inside’ people in ways not anticipated and thus create new performance arenas for the expression of identity. Drawing on the ideas of Butler and Foucault and theories of performativity, this paper examines a new context for human-computer interaction and articulates potentially disturbing issues with monitoring (...) health rather than wellbeing. It argues that by adopting explicitly social framings we can see beyond the idea of medical interventions for health to recognize the political implications of the new categorizations and their implementation in code. In the process, it critiques traditional ways of understanding machine-body relations within the field of technology design. (shrink)

Universal access to health care has historically faced strident opposition from political conservatives in the United States, although it has long been accepted by most conservatives in the rest of the industrialized world. Now, in a global economy where American business is crippled by the rising cost of market-based health care, the time may be ripe for change. The key to fostering a new mindset among American conservatives is to show why universal access fulfills many of the basic values that (...) all conservatives hold. (shrink)

The promotion of human rights, the punishment of crimes against humanity, the use of force with respect to humanitarian intervention: these are some of the complex issues facing governments in recent years. The contributors to this book offer a theoretical and empirical approach to these issues. Three leading normative theorists first explore what an 'ethical foreign policy' means. Four contributors then look at potential or actual instruments of ethical foreign policy-making: the export of democracy, non-governmental organisations, the International Criminal Court, (...) and bottom-up public pressure on governments. Finally, three case studies examine more closely developments in the foreign policies of the US, the UK, and the European Union, to assess the difficulties raised by the incorporation of ethical considerations into foreign policy.

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham responds to this dilemma, his (...) razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

We live in a world confronted by mounting environmental problems; increasing global deforestation and desertification, loss of species diversity, pollution and global warming. In everyday life people mourn the loss of valued landscapes and urban spaces. Underlying these problems are conflicting priorities and values. Yet dominant approaches to policy-making seem ill-equipped to capture the various ways in which the environment matters to us. Environmental Values introduces readers to these issues by presenting, and then challenging, two dominant approaches to environmental decision-making, (...) one from environmental economics, the other from environmental philosophy. The authors present a sustained case for questioning the underlying ethical theories of both of these traditions. They defend a pluralistic alternative rooted in the rich everyday relations of humans to the environments they inhabit, providing a path for integrating human needs with environmental protection through an understanding of the narrative and history of particular places. The book examines the implications of this approach for policy issues such as biodiversity conservation and sustainability. Written in a clear and accessible style for an interdisciplinary audience, this volume will be ideal for student use in environmental courses in geography, economics, philosophy, politics and sociology.

One of the three consequences of Einstein’s theory of general relativity was the curvature of light passing near a massive body. In 1911, he published a first value of the angle of deflection of light, then a second value in 1915, equal twice the first. In the early 1920s, when he received the Nobel Prize in Physics, a violent controversy broke out over this result. It was then disclosed that the first value he had obtained in 1911 (...) had been calculated more than a century before by a German astronomer named Johann von Soldner. The aim of this article is therefore to compare the methods used by Soldner and then by Einstein leading to this first value and to explain the importance of the doubling of this value in the framework of Einstein’s theory of general relativity. Such a consequence of this theory lies at the intersection of several scientific fields such as Mathematics, Physics, Astronomy and Philosophy. (shrink)
