This is a short expository account of the regularity lemma for stable graphs proved by the authors, with some comments on the model theoretic context, written for a general logical audience.

The phenomenon whereby severely disabled persons self-report a higher than expected level of subjective well-being is called the “disability paradox.” One explanation for the paradox among brain injury survivors is “response shift,” an adjustment of one’s values, expectations, and perspective in the aftermath of a life-altering, disabling injury. The high level of subjective well-being appears paradoxical when viewed from the perspective of the non-disabled, who presume that those with severe disabilities experience a quality of life so poor that it might (...) make their lives not worth living. This presumption has profound consequences, for it may inform end-of-life choices made in advance directives, or influence decisions made by surrogates on behalf of persons who are unable to direct their own medical treatment. -/- Peterson et al propose a cautious, well-considered plan to use fMRI-based brain-computer interfaces to assess the decision making capacity of covertly aware, behaviorally non-responsive individuals who retain high levels of preserved cognition. Their plan, if it succeeds, could eventually restore autonomy and empower some severely disabled persons, allowing them to participate in clinical decision making. Peterson et al discuss possible in-principle objections to their proposal, among them the “argument from psychological health,” and the “changing sets of values” objection. These objections both presume that deviations from a pre-injury norm could indicate diminished decision making capacity. This presumption threatens the autonomy of the patient who is capable of making decisions, but whose post-injury decisions appear to diverge from pre-injury preferences or values. In light of the potential for response shift, and the disability paradox, it should not be inferred that changes in values or preferences are unreflective of the true current preferences of a brain-injured person, nor are they conclusive evidence of diminished capacity. Presuming diminished capacity on the basis of unexpected or unconventional preferences has, in the past, been used to disempower patients whose autonomy and capacity would not have been doubted had they made choices that accorded with the expectations or values of others. We must be cautious, and vigilant, to prevent similarly diminishing the autonomy of covertly aware, behaviorally non-responsive individuals on the basis of empirically and ethically questionable inferences about their decision making capacity.

As contribution to a recent debate (James, 1998; Murphy etal., 1997, 1998) the proportion of twins following ovulation induction (OI) or assisted conception (AC) in 1994 in Oxfordshire and West Berkshire was estimated, and by extrapolation the natural twinning rate in England and Wales was judged to have maintained a plateau phase since the 1970s. Similar figures for 1995 and 1996 from the same study, and hence a more stable local estimate, are now provided. The proportions, as before, were estimated (...) from women's responses to a questionnaire within a case[hyphen]control study, with ascertainment from general practitioners' records or hospital case[hyphen]notes for non[hyphen]responders or for those excluded from the study originally. In 1994, 1995 and 1996 the proportion of twins following OI/AC was overall 27% (24%, 30% and 27% respectively). Restriction to the 87% locally resident made no difference. The national crude twinning rate for those years was overall 13·3 per 1000 maternities (12·8, 13·6 and 13·4 respectively). (shrink)

This paper defends a neorepublican account of civic virtue as consisting of stable traits of character, understood in broadly Aristotelian terms, that exhibit excellences associated with the role of citizen, and that contribute to the secure protection of freedom as non-domination. Such an account is important for the neorepublican project because neither laws nor social norms can yield reliable support for republican freedom without a parallel input from civic virtue. The paper emphasizes the need to distinguish civic virtue from desirable (...) norms, which can operate in tandem. Against other neorepublican accounts of civic virtue, it argues that the primary function of such virtue is not to support the stability of republican regimes. Rather, it has a corrective function, and may in fact challenge institutions, laws, and informal norms if they allow for the exercise of arbitrary power. Finally, the paper argues that this account of civic virtue is better positioned than a stability-focused account to shed light on the relationship between civic virtue and the common good. (shrink)

Implicit processes almost certainly preceded explicit processes in our evolutionary history, so they are likely to be more resistant to disruption according to the principles of evolutionary biology [Reber, A. S. . The cognitive unconscious: An evolutionary perspective. Consciousness and Cognition, 1, 93–133.]. Previous work . Knowledge, nerves and know-how: The role of explicit versus implicit knowledge in the breakdown of a complex motor skill under pressure. British Journal of Psychology, 83, 343–358.]) has shown that implicitly learned motor skills remain (...) stable under psychological pressure and concurrent cognitive demands, and recently [Poolton, J. M., Masters, R. S. W., & Maxwell, J. P. . Passing thoughts on the evolutionary stability of implicit motor behaviour: Performance retention under physiological fatigue. Consciousness and Cognition, 16, 456–468.] showed that they also remain stable under conditions of anaerobic fatigue that would have significantly challenged the survival skills of our ancestors. Here we examine the stability of an implicitly learned motor skill under fatigue conditions that primarily tax a different physiological system , but which have equally strong evolutionary connotations. Participants acquired a throwing task by means of an errorless learning method or an errorful method. Motor performance in the errorless condition, but not the errorful condition, remained stable following an exhaustive VO2 max. running test. Our findings replicate and extend the work of Poolton et al., providing further support for Reber’s evolutionary distinction between implicit and explicit processes. (shrink)

If all differences in behavior are explainable in terms of universal values pursued under variable constraints, then much ethical theorizing is pointless. A strong presumption in favor of universal values can be established by showing that differences in behavior that were previously thought to be explainable only in terms of differences in values, can in fact be explained in terms of differences in constraints. Eleven such cases are briefly discussed, including cases of differences among racial, religious and other groups in (...) crime, culinary practices and the acceptance of innovation. (shrink)

More than one third of the human brain is devoted to the processes of seeing - vision is after all the main way in which we gather information about the world. But human vision is a dynamic process during which the eyes continually sample the environment. Where most books on vision consider it as a passive activity, this book is unique in focusing on vision as an 'active' process. It goes beyond most accounts of vision where the focus is on (...) seeing, to provide an integrated account of seeing AND looking. The book starts by pointing out the weaknesses in our traditional approaches to vision and the reason we need this new approach. It then gives a thorough description of basic details of the visual and oculomotor systems necessary to understand active vision. The book goes on to show how this approach can give a new perspective on visual attention, and how the approach has progressed in the areas of visual orienting, reading, visual search, scene perception and neuropsychology. Finally, the book summarises progress by showing how this approach sheds new light on the old problem of how we maintain perception of a stable visual world. Written by two leading vision scientists, this book will be valuable for vision researchers and psychology students, from undergraduate level upwards. (shrink)

This paper is perhaps an impressionistic response to accounts of the extraordinary set-theoretical activity being undertaken by W. Hugh Woodin and colleagues in the present moment, in the context of the mathematical ontology proposed and elaborated by Alain Badiou. The argument presented is that the prevailing and sustained incoherence of the mathematical ontology underscores a contemporary deficit of humanity’s symbolic organization which, in turn, yields confusion and conflict in terms of subjective orientation. But a new axiom promises to realize a (...) coherent set theory, i.e. stable, consistent and complete. This remarkable development offers hope for the pursuit of a modern symbolic, and a consequent resolution of the general subjective disorientation. (shrink)

That Jefferson execrated Plato in an 1814 letter to friend John Adams. In it, he expresses an unsympathetic, hostile view of Plato’s Republic, and the reasons are several. Nonetheless, Plato’s views on what makes government fundamentally sound are, at base, remarkably similar to Jefferson’s both in substance and sentiment, so much so that it is inconceivable to think that Plato’s Republic had little effect on Jefferson’s political thinking. That makes his execration of Plato difficult to understand. This paper is an (...) attempt to show that Jefferson, despite the tenor of his letter to Adams, had much more than a dilettante’s grasp of the political content of Plato’s major work. Jefferson was very likely quite familiar with the work, since his own political philosophy assimilates key substratal Platonic political principles of good, stable governing. His disavowal of the work and execration of Plato, then, is due to a constellation of other factors: Adams’s feelings toward Plato, Jefferson’s views on the corruptions of Jesus’s teachings, his deep-dyed detestation of metempiricism, his view that Plato was an unoriginal thinker, and strong disagreement with Plato’s means to instantiate substratal political principles.

Neuroimaging is critical in the diagnosis and treatment of brain cancers; however, the first detection of tumors is a challenge. Detection techniques like image segmentation are heavily reliant on the segmented image’s resolution. Magnetic resonance imaging tumor segmentation has emerged as a new study area in the medical imaging field. This spongy and delicate mass of tissue is the brain. Stable conditions allow for patterns to enter and interact with each other. To put it simply, a tumor is a mass (...) of tissue that has grown unchecked by the natural mechanisms that keep it under control. When cells divide uncontrollably, they create a cancerous tumor. Brain tumors can be detected and segmented using a variety of methods. A new method for detecting brain tumors using MRI images is presented in this research. An innovative Woelfel filter is used for enhancement, and morphological segmentation approaches combined with anisotropic diffusion are used for segmentation. Segmentation of brain tumors can be accomplished using thresholding and morphological techniques, which are both effective. The tumor will be located and identified using morphological image processing. Image denoising refers to the process of removing artefacts such as noise and aliasing from digital images. Here MATLAB programming language is utilised as it incorporates all the toolboxes required for the application involved in the work. (shrink)

The purpose of the study is to conceptualise Islamic workplace rectitude. Based on a comprehensive literature review, the study proposes that Islamic workplace rectitude is composed of a harmonious blend of Islamic workplace spirituality, Islamic workplace ethics, and submission to Allah. The study involved an inductive interpretive analysis, where critical aspects of workplace rectitude were extracted based on the agreed-upon Qur’anic verses and Hadith. The study augments the literature on workplace behaviour through divine command theory by offering new theoretical evidence (...) from an Islamic perspective. As presented in the current study, Islamic workplace rectitude is a higher-order, stable psychological construct that can be distinguished from other constructs. It comprises Islamic workplace spirituality, Islamic workplace ethics, and submission to Allah. However, further research is needed to accomplish conceptual and empirical distinctiveness for the proposed construct of Islamic workplace rectitude. This study presents an alternative approach to Islamic workplace behaviour, facilitating fresh insights and further development and research in this exciting area. The study adopts a holistic approach, contributing to identifying commonalities between workplace attitudes and Islam. It introduces Islamic workplace rectitude, a novel concept not present in the existing literature. The present work is, therefore, expected to trigger further interest and research in Islamic workplace rectitude. (shrink)

This article offers reinterpretation of the current economic and political crisis through the lens of Gramsci’s concept of “interregnum,” departing from the model of “punctured equilibrium” to analyze the specific political dynamics of nonhegemonic periods between the breakdown of one ideological order and the emergence of a new one. Although political science has a range theories about periods of hegemony and paradigmatic stability, the periods between stable hegemonies remain distinctly undertheorized. A theoretical concept describing periods of interregnum is offered and (...) applied to the changes in economic ideology and political alignments that followed the breakdown of the liberal order in the interwar period and the postwar Keynesian consensus of the 1970s. The concept is then applied to the current juncture, in which the hegemony of neoliberalism has been shaken by the 2008 financial crisis but no clear successor has emerged. (shrink)

We study the handicap principle in terms of the Sir Philip Sidney game. The handicap principle asserts that cost is required to allow for honest signalling in the face of conflicts of interest. We show that the significance of the handicap principle can be challenged from two new directions. Firstly, both the costly signalling equilibrium and certain states of no communication are stable under the replicator dynamics ; however, the latter states are more likely in cases where honest signalling should (...) apply. Secondly, we prove the existence and stability of polymorphisms where players mix between being honest and being deceptive and where signalling costs can be very low. Neither the polymorphisms nor the states of no communication are evolutionarily stable, but they turn out to be more important for standard evolutionary dynamics than the costly signalling equilibrium.

Recent philosophy of measurement has emphasized the existence of both diachronic and synchronic “loops,” or feedback processes, in the epistemic achievements of measurement. A widespread response has been to conclude that measurement outcomes do not convey interest-independent facts about the world, and that only a coherentist epistemology of measurement is viable. In contrast, I argue that a form of measurement realism is consistent with these results. The insight is that antecedent structure in measuring spaces constrains our empirical procedures such that (...) successful measurement conveys a limited, but veridical knowledge of “fixed points,” or stable, interest- independent features of the world.

The purpose of this special issue and the conference that inspired it was to address the issue of conceptual integration in a science of consciousness. We felt this to be important, for while current efforts to scientifically investigate consciousness are taking place in an interdisciplinary context, it often seems as though the very terms being used to sustain a sense of interdisciplinary cooperation are working against it. This is because it is this very array of common concepts that generates a (...) sense of unity among consciousness researchers, despite the fact the concepts mean different things in different disciplines. These Concepts of Consciousness include the following: realism, representation, intentionality, information, control, memory and self. Given this list, we believed we could best approach the issue of potential conceptual integration by addressing each concept from different perspectives and asking the following: how do uses of the concept differ, must these meanings be synthesized in order for there to be a unified science of consciousness, is a unified conceptual scheme necessary to establish an independent science of consciousness, is a unified conceptual scheme possible, if it is not possible, why not, and if it is possible, what might it look like? To this end we invited, for each concept, two scholars who made extensive use of the identified concept in their work. The papers entailed in this special issue constitute the outcome of this effort, and in what follows we offer a brief examination of possible forms of integration the papers seem to collectively suggest.

If the a priori is the proper subject matter of transcendental philosophy, then the problems of the a priori are also problems for transcendental philosophy. the idea that defines transcendental philosophy is the idea that there are stable general structures which are discernible in experience, provide the foundations of our knowledge of it, and collectively constitute an a priori which transcends experience and informs it. the a priori is traditionally conceived as a nexus of relations which is held to be (...) logically/temporally prior to experience and responsible for its organization. in this essay, i challenge this traditional (kantian) understanding of the a priori and set forth an alternative to it based on the writings of maurice merleau-ponty. the intent is to provide a new conception of transcendental philosophy.

Shared intention normally leads to joint action. It does this, it is commonly said, only because it is a characteristically stable phenomenon, a phenomenon that tends to persist from the time it is formed until the time it is fulfilled. However, the issue of what the stability of shared intention comes down to remains largely undertheorized. My aim in this paper is to remedy this shortcoming. I argue that shared intention is a source of moral and epistemic reasons, that responsiveness (...) to such reasons on the part of each individual reinforces her own relevant attitudes, and that this enhances the stability of the shared intention as a whole. We thus discover an important self-reinforcing and stability-enhancing mechanism at the heart of shared intention and action. It follows from this proposal that the psychological commitment that an individual exhibits in joint action is normally a function not only of her own participatory intention, as often maintained, but also of her endorsement of the reasons created by her group’s shared intention to so act.

In lieu of an abstract, here is a brief excerpt of the content:Gender Ideology and the “Artistic” Fabrication of Human Sex: Nature as Norm or the Remaking of the Human?Michele M. SchumacherUntil quite recently,” the famous English novelist C. S. Lewis remarked in 1959, “it was taken for granted that the business of the artist was to delight and instruct his public”: that is to say, to address simultaneously their passions and their intellects. “There were, of course, different publics.... And (...) an artist might lead his public on to appreciate finer things than they had wanted at first; but he could do this only by being; from the first, if not merely entertaining, yet entertaining, and if not completely intelligible, yet very largely intelligible.” This constraint—let us call it intelligent (or purposeful) design, in keeping with a basic analogy that we will draw upon in these pages—had however been lost, Lewis observed. Hence, even “in the highest aesthetic circles one now hears nothing about the artist’s duty to us. It is all about our duty to him. He owes us nothing; we owe him ‘recognition,’ even though he has never paid the slightest attention to our tastes, interests, or habits.”1 In short, the artist of modernity need not pay the slightest attention to an intention, not even his own. Modern art need not be an expression of intelligence or [End Page 363] understanding; it is expression as such (tout court): personal and autonomous.2Lewis’s remarks do not point merely to the increasingly relativist tendencies of art in the Western world, to the lack of objective criteria or norms governing the artistic disciplines. They also point to the growing disregard among artists for the sociocultural expectations of their publicum. Mediating between the two is, without a doubt, the basis upon which both artistic and social norms were traditionally founded: nature, which served as a classic analogy for both art (understood in the broad sense, so as to include not only the fine arts, but also technology and practical sciences) and ethics in virtue of nature’s intrinsic inclination towards its defining end and perfection.With regard to the first of these analogies (that of art and nature), Mark Schiefsky explains that although art does bring about “results that nature itself cannot,” it does so in the classic understanding “by acting in a natural way—the way nature would act if it could generate the products of art.”3 As for the difference between the two, nature is moved to its specifying end by way of intrinsic inclinations that are implicit to it, whereas a work of art is moved to its end extrinsically, and thus with more or less violence.4 A sculptor, for example, who introduces a form into a piece of marble, does so by chiseling [End Page 364] and hammering away at the fine stone.5 “Art is,” Aristotle explains, “the principle and form of the thing that comes to be [let us say, a sculpture]; but it is located elsewhere [in, for example, the artist’s mind or in a sketch that he has made] than in that thing, whereas the movement of nature is located in the thing itself that comes to be [a tree, for example, or a baby], and is derived from another natural organism [a tree or human parents] which possessed the form in actuality.”6This classic distinction between art and nature parallels the distinction between art and ethics. Ethics “does not affect human action in the same way as do art and technique,” Servais Pinckaers explains. Unlike art and technique, which are concerned with “the external work produced by human action”—this painting or that machine, for example—ethics is concerned with an immanent principle, qualifying the actor as such: the stable dispositions (or habitus: virtues or vices) at the origin of “the active willing that is the principle source of the action.”7 This immanent principle at the source of ethical action is—to complete our analogy—creative in only a limited sense. The human person is indeed free to choose, but he or she is not free to decide “what is good or evil” as such, nor what is “good or bad for... (shrink)

We show how more general knowledge can be built in information security, by the building of knowledge of mechanism clusters, some of which are multifield. By doing this, we address in a novel way the longstanding philosophical problem of how, if at all, we come to have knowledge that is in any way general, when we seem to be confined to particular experiences. We also address the issue of building knowledge of mechanisms by studying an area that is new to (...) the mechanisms literature: the methods of what we shall call mechanism discovery in information security. This domain offers a fascinating novel constellation of challenges for building more general knowledge. Specifically, the building of stable communicable mechanistic knowledge is impeded by the inherent changeability of software, which is deployed by malicious actors constantly changing how their software attacks, and also by an ineliminable secrecy concerning the details of attacks not just by attackers, but also by information security defenders as they protect their methods from both attackers and commercial competitors. We draw out ideas from the work of the mechanists Darden, Craver, and Glennan to yield an approach to how general knowledge of mechanisms can be painstakingly built. We then use three related examples of active research problems from information security to develop philosophical thinking about building general knowledge using mechanisms, and also apply this to develop insights for information security. We show that further study would be instructive both for practitioners and for philosophers. (shrink)

The properties of negation, in combination with those of other logical operations and structural features of the deductibility relation, serve as gateways among logical systems. Negation therefore plays an important role in selecting logical systems for particular applications. This volume provides a thorough treatment of this concept, based on contributions written by authors from various branches of logic. The resulting 14 research papers address a variety of topics including negation in relevant logics; a defense of dialetheic theory of negation; stable (...) negation in logic programming; antirealism and falsity; and negation, denial, and language change in philosophical logic. Suited to scholars and graduate students in the fields of philosophy, logic mathematics, computer science, and linguistics. Annotation copyrighted by Book News, Inc., Portland, OR. (shrink)

There are two conspicuous and inescapable features of this world in which time is real. One experiences a world in flux, a transient world in which things constantly come into existence, change and cease to be. One also experiences a stable world, one in which how things are at any given moment is permanent, unchangeable. Thus, there is transience and permanence. Yet these two features of the world seem incompatible. The primary purpose of this paper is to sketch a metaphysics (...) of time that embraces both features. Crucial to this undertaking is the notion of becoming, that is, coming into existence. I distinguish three distinct phenomena of becoming: temporal, absolute and atemporal. The last is the least familiar of these; it is the phenomenon of coming into existence outside of time. Although the idea that there are things that do not exist in time is not unfamiliar, it is largely taken for granted that if anything comes into existence, it must do so in time. (Indeed, I suspect many think that the idea of a thing coming to be outside of time is simply incoherent.) In this paper, I articulate and defend the notion of atemporal becoming. It is by means of this notion that one can develop a fully satisfactory metaphysics of time, one that honors both transience and permanence and finds for each its proper domain within the world.

Messaging from U.S. authorities about COVID-19 has been widely divergent. This research aims to clarify popular perceptions of the COVID-19 threat and its effects on victims. In four studies with over 4,100 U.S. participants, we consistently found that people perceive the threat of COVID-19 to be substantially greater than that of several other causes of death to which it has recently been compared, including the seasonal flu and automobile accidents. Participants were less willing to help COVID-19 victims, who they considered (...) riskier to help, more contaminated, and more responsible for their condition. Additionally, politics and demographic factors predicted attitudes about victims of COVID-19 above and beyond moral values; whereas attitudes about the other kinds of victims were primarily predicted by moral values. The results indicate that people perceive COVID-19 as an exceptionally severe disease threat, and despite prosocial inclinations, do not feel safe offering assistance to COVID-19 sufferers. This research has urgent applied significance: the findings are relevant to public health efforts and related marketing campaigns working to address extended damage to society and the economy from the pandemic. In particular, efforts to educate the public about the health impacts of COVID-19, encourage compliance with testing protocols and contact tracing, and support safe, prosocial decision-making and risk assessment, will all benefit from awareness of these findings. The results also suggest approaches, such as engaging people's stable values rather than their politicized perspectives on COVID-19, that may reduce stigma and promote cooperation in response to pandemic threats.

The ethical obligation to provide a reasonably safe discharge option from the inpatient setting is often confounded by the context of homelessness. Living without the security of stable housing is a known determinant of poor health, often complicating the safety of discharge and causing unnecessary readmission. But clinicians do not have significant control over unjust distributions of resources or inadequate societal investment in social services. While physicians may stretch inpatient stays beyond acute care need in the interest of their patients (...) who are experiencing homelessness, they must also consider the implications of using an inpatient hospital bed for someone without the attendant level of medical need. Caring for patients in an inpatient setting when they no longer require acute care means fewer beds for acute care patients. And when a patient who is experiencing homelessness declines a medically safer option such as a skilled nursing facility, then clinicians may be faced with the sole option of discharge to the street, which raises troubling questions of nonmaleficence and social justice. Here we investigate the different forms of injustice that play out when patients are discharged to the street, and offer a map of the interwoven ethical responsibilities of clinicians, hospitals, and skilled nursing facilities.

In lieu of an abstract, here is a brief excerpt of the content:Life in LimboM. ChiuWhen my son was 7 years old, he began complaining of headaches. They were frequent, but never seemed severe. “I have a headache!” was always followed by “Can I watch TV?” I didn’t believe the pain was real until it woke him up in the middle of the night. I knew then that something must be wrong. I approached our pediatrician, who said it sounded like (...) migraines, but we should order an MRI to rule anything out. The appointment was scheduled several months in advance, and I always had the urge to cancel it. I was pretty sure my son just wanted to watch TV. The pediatrician told me I might as well do the MRI. He told me that if we skipped it and something was wrong, I would never be able to live with the regret. We kept the Monday morning appointment, and went to the MRI expecting reassurance that nothing was wrong. Instead, we got a phone call later that day. They needed to see us on immediately, but wouldn’t tell me why. Of course, I knew something was wrong. “Is it a tumor?” I asked. “This isn’t something we can discuss on the phone” was the answer I got. An appointment was scheduled for Wednesday. Two days might be “immediately” to medical professionals, but to a parent who just heard that her child had an abnormal MRI, it was an eternity. I planned my son’s funeral in those two days.Our meeting with the Neurologist began with reviewing the MRI. “See this spot here? It shouldn’t be there”. A tumor. 1 ½ × 1 ½ × 2 ½ cm tumor, in the right thalamus. Small, they said. Looks like a Low Grade Glioma they said. The kind of tumor you want to have, if you have to have a brain tumor. A biopsy was scheduled for two weeks later. The [End Page E2] biopsy confirmed it was a Juvenile Pilocytic Astrocytoma (JPA). The neurosurgeon was confident she could remove all of the tumor. We were at one of the best Children’s Hospitals in the world. We were in good hands.A few days before the surgery, a friend who is a medical doctor suggested we get a second opinion. “It couldn’t hurt, it could help”, my husband said. Fortunately, he just sold a start–up company, and was planning to take a few months off from work before starting his next venture. He had time to research, talk to friends in the medical field and make phone calls.Our second opinion from another leading hospital reviewed the MRI’s with us. The neurosurgeon asked, “Did they say tumor? One?” Yes, they did. “See this here?” he said, pointing to a second spot on the MRI. He said it was possibly a second tumor, or more likely, an extension of the first. It was in inoperable location. Surgery wasn’t an option. Chemo would be our best choice. Why would we cut into our son’s brain to remove part of the tumor when he would need to do chemo anyway? Why not try chemo first?I would like to say that we do not fault our original neuro–oncology team for missing this second abnormality. It is hard to notice an ant in the room when there is an elephant staring at you. People make mistakes, and tumors don’t always look the same. That’s what second opinions are for. That is why doctors should encourage patients to get second opinions.We scheduled the surgery for port implantation, and got busy educating ourselves about chemo regimes. It was going to be a long journey. 18 months of transfusions with a pretty low success rate and a high rate of secondary complications. Unsure if we were doing the right thing, we got a third opinion. I am so grateful that my husband was between jobs and had time to devote to finding the best possible treatment for our son. We were financially stable and had great insurance. What do people do when they don’t have this luxury?By now, several months had passed since our first MRI. Our... (shrink)

Recently, many comparativists and democratic theorists have argued that democracy is in imminent peril, even in countries that are thought to be its strongholds. But theorists like Andrew Gamble, Wolfgang Streeck, and David Runciman suggest that some democracies are too embedded to collapse. Instead, they argue these democracies are experiencing long-term structural crises. This article explains how this alternative kind of crisis works. It conceives of legitimacy crises as ‘chronic crises’ in which democratic procedures are contested even as the democratic (...) political system is affirmed. In these crises, democracies are threatened by distortion and deadlock rather than death. The article gives a precise account of chronic legitimacy crises. It treats legitimacy as a scalar concept, going beyond binary views where legitimacy is something a state either has or lacks. It distinguishes periods of chronic crisis from stable periods and from acute crises. It shows how chronic crises are distinctively about legitimacy. It carves out conceptual space for a different kind of legitimacy crisis, and it assists comparativists in thinking about how younger democracies differ from older ones. (shrink)

A stable democracy requires a shared identity and political culture. Its citizens need to identify as one common demos lest it fracture and balkanise into separate political communities. This in turn necessitates some common communication network for political messages to be transmitted, understood and evaluated by citizens. Hence, what demarcates one demos from another are the means of communication connecting the citizens of those demoi, allowing them to debate and persuade each other on the proper conduct of government and on (...) issues of common interest. For the ancient Athenians, their public sphere was the agora (marketplace); for the Federalists in the American colonies, the newspaper; for us today, it is the Internet. Until now, the physical nature of these communication networks has resulted in a trade-off between the reach of political messages (the numeric and geographic composition of the demos who receive political messages and may participate in the public sphere) and the ability to target the content of a message on that network towards individual citizens. One-to-one interpersonal conversation in the agora was highly targeted but could reach only as far as a voice could carry. The speakers and audience were well known to each other through personal interaction. As the printing press and later television allowed for greater and greater reach, the content of these messages became more generic as the speakers became more distant from their audience. The wider the audience grew, the less a message could be targeted at a particular audience segment without alienating others. (shrink)

Sacred Harp singers the world over gather weekly to sing out ofThe Sacred Harp, a collection of shape-note songs first published in 1844. Their tradition is highly ritualized, and it plays an important role in the lives of many participants. Following the implementation of lockdown protocols to combat the COVID-19 pandemic, groups of Sacred Harp singers quickly and independently devised a variety of means by which to sing together online using Zoom, Jamulus, and Facebook Live. The rapidity and creativity with (...) which Sacred Harp singers developed ways to sustain their activities attests to the strength and significance of this community of practice, and in this article I describe each modality and provide an account of how it came to be developed and widely used. As a participant-observer, I completed extensive fieldwork across these digital sites and conducted semi-structured interviews with 22 other singers. I found that online singing practices have reshaped the Sacred Harp community. Many singers who did not previously have the opportunity to participate now have access, while others have lost access due to technological barriers or lack of interest in online activities. At the same time, geographical barriers have disintegrated, and singing organizers must make an effort to maintain local identity. A stable community of singers has emerged in the digital realm, but it is by no means identical to the community that predated the pandemic. I also identify the ways in which online singing has proven meaningful to participants by providing continuity in their personal and communal practice. Specifically, online singing allows participants to access and celebrate their collective memories of the Sacred Harp community, carry out significant rituals, and continue to grow as singers. While no single modality replicates the complete Sacred Harp singing experience, together they function “like pieces in a puzzle”, allowing individual participants to access many of the elements of Sacred Harp singing that are most meaningful to them.

The description Ausonius has given us of his family and of the teachers and professors of Bordeaux in the mid-fourth century is exceptional among our sources because of its detail and completeness. There is no reason to suppose that the picture he gives is untypical of life in the provinces and it makes a welcome change from the histories of aristocratic politics at Rome or Constantinople. It provides an excellent opportunity for a pilot study in which we may see how (...) the conflicting elements of social status were in practice reconciled and applied. In the traditional, and still prevalent view, the society of the Later Roman Empire was ‘crushed … in the iron clamp of castes separated from one another by barriers which could not be passed’. The evidence of Ausonius suggests that this judgement should be qualified. The society of the fourth century may have been stable. It was not static. (shrink)

This dissertation contends that emotions are subject to ethical assessment, not simply as motives or overt expressions, but in their own right. Emotions, I argue, are subject to assessment because they are aspects of a person's character. Specifically, emotions involve voluntary acts of attention, which are due to habituation. These acts show character by manifesting certain stable, deeply-held desires called 'concerns.' This view, dubbed 'Attentional Voluntarism,' is opposed to the prevalent view, dubbed 'Rationalism,' that emotions are subject to assessment because (...) of their propositional content. Rationalism is unable to account for certain kinds of irrational emotion, where one forms an unwarranted emotion to avoid anxiety and secure pleasure. It exaggerates how mature and adaptive these emotions are. Attentional Voluntarism, by contrast, accounts for the childish and even infantile character behind such emotions, because the relevant habits of attention may simply be the residue from previous developmental stages.

In this paper we show that there are certain limits as to what applications of Maynard Smith’s concept of evolutionarily stable strategy can tell us about evolutionary processes. We shall argue that ESS is very similar in spirit to a particular branch of rational choice game theory, namely, the literature on refinements of Nash equilibrium. In the first place, ESS can also be viewed as a Nash equilibrium refinement. At a deeper level, ESS shares a common structure with other rational (...) choice equilibrium refinements. An equilibrium is evaluated according to whether it persists under specific kinds of perturbations. In the case of ESS, these perturbations are mutations. However, from a dynamical point of view, focusing exclusively on perturbations of equilibria provides only a partial account of the system under consideration. We will show that this has important consequences when it comes to analyzing game-theoretic models of evolutionary processes. In particular, there are non-ESS states which are significant for evolutionary dynamics. (shrink)

The Moral Foundations of Trust seeks to explain why people place their faith in strangers, and why doing so matters. Trust is a moral value that does not depend upon personal experience or on interacting with people in civic groups or informal socializing. Instead, we learn to trust from our parents, and trust is stable over long periods of time. Trust depends on an optimistic world view: the world is a good place and we can make it better. Trusting people (...) are more likely to give through charity and volunteering. Trusting societies are more likely to redistribute resources from the rich to the poor. Trust has been in decline in the United States for over 30 years. The roots of this decline are traceable to declining optimism and increasing economic inequality, which Uslaner supports by aggregate time series in the United States and cross-sectional data across market economies.

As these opening quotes acknowledge, the Prisoner’s Dilemma (PD) represents a core puzzle within the formal mathematics of game theory.3 Its rise in conspicuity is evident figure 2.1 above demonstrating a relatively steady rise in incidences of the phrase’s usage between 1960 to 1995, with a stable presence persisting into the twenty first century. This famous two-person “game,” with a stock narrative cast in terms of two prisoners who each independently must choose whether to remain silent or speak, each advancing (...) self-interest at the expense of the other and thereby achieving a mutually suboptimal outcome, mires any social interaction it is applied to into perplexity. The logic of this game proves the inverse of Adam Smith’s invisible hand: individuals acting on self interest will achieve a mutually suboptimal outcome. However, as this chapter illuminates, the assumptions underlying game theory drive this conclusion. (shrink)

The basic structural units of society, as a highly organized social system, are social institutions, which allow to create a strong and stable system of relations between people, to form a social order. Leadership is one of the main elements that ensures the functioning of a social institute. The specific traits and particular attributes of political leadership are actively explored by scholars, while spiritual leadership with its particular characteristics remains unaddressed. In the modern world, the institute of leadership in Judaism (...) has a significant impact on its followers, and therefore it is important to study the historical roots of this phenomenon, the mechanisms of influence of the leader on the followers of the current and directly determine the role of the spiritual leader in the preserved national traditions of Judaism.

In the process of implementing an ethical code of conduct, a business organization uses formal methods. Of these, training, courses and means of enforcement are common and are also suitable for self-regulation. The USA is encouraging business corporations to self regulate with the Federal Sentencing Guidelines (FSG). The Guidelines prescribe similar formal methods and specify that, unless such methods are used, the process of implementation will be considered ineffective, and the business will therefore not be considered to have complied with (...) the guidelines. Business organizations invest enormous funds on formal methods. However, recent events indicate that these are not, by themselves, yielding the desired results. Our study, based on a sample of 812 employees and conducted in an Israeli subsidiary of a leading multinational High-Tech corporation headquartered in the US, indicates that, of the methods used in the process of implementation, one of the informal methods (namely, the social norms of the organization) is perceived by employees to have the most influence on their conduct. This result, when examined against employee tenure, remains relatively stable over the years, and stands in contradistinction to the formalistic approach embedded in the FSG. We indirectly measure the effectiveness of the percieved most influential implementation process methods by analyzing their impact on employee attitudes (namely, personal ethical commitment and employees'' commitment to organizational values). Our results indicate that the informal methods (manager sets an example or social norms of the organization) are likely to yield greater commitment with respect to both employee attitudes than the formal method (training and courses on the subject of ethics). The personal control method (my own personal values) differs significantly from all the other methods in that it yields the highest degree of personal ethical commitment and the lowest degree of employees'' commitment to organizational values.

This forum contribution addresses two major themes in de Goede’s original essay on ‘Financial security’: (1) the relationship between stable markets and the proverbial ‘security dilemma’; and (2) the development of new decision-technologies to address risk in the post-World War II period. Its argument is that the confluence of these two themes through rational choice theory represents a fundamental re-evaluation of the security dilemma and its relationship to the rule of law governing market relations, ushering in an era of perpetual (...) physical and financial insecurity.

This manuscript considers the transmission dynamics of lymphatic filariasis with some intervention strategies in place. Unlike previously developed models, our model takes into account both the exposed and infected classes in both the human and mosquito populations, respectively. We also consider vaccinated, treated and recovered humans in the presented model. The global dynamics of the proposed model are completely determined by the basic and effective reproduction numbers. We then use Lyapunov function theory to find the sufficient conditions for global stability (...) of both the disease-free equilibrium and endemic equilibrium. The Lyapunov functions show that when the basic reproduction number is less than or equal to unity, the disease-free equilibrium is globally asymptotically stable, and when it is greater than unity then the endemic equilibrium is also globally asymptotically stable. Finally, numerical simulations are carried out to investigate the effects of the intervention strategies and key parameters to the spread of lymphatic filariasis. The numerical simulations support the analytical results and illustrate possible model behavioral scenarios. (shrink)
