This paper describes an AFOSR-supported basic research program that focuses on developing a new framework for combining hard with soft data in order to improve space situational awareness. The goal is to provide, in an automatic and near real-time fashion, a ranking of possible threats to blue assets (assets trying to be protected) from red assets (assets with hostile intentions). The approach is based on Conceptual Spaces models, which combine features from traditional associative and symbolic cognitive models. While Conceptual Spaces (...) are revolutionary, they lack an underlying mathematical framework. Several such frameworks have attempted to represent Conceptual Spaces, but by far the most robust is the model developed by Holender. His model utilizes integer linear programming in order to obtain an overall similarity value between observations and concepts that support the formation of hypotheses. This paper will describe a method for building Conceptual Spaces models for threats that utilizes ontologies as a means to provide a clear semantic foundation for this inferencing process; in particular threat ontologies and space domain ontologies are developed and employed in this approach. A space situational awareness use-case is presented involving a kinetic kill scenario and results are shown to assess the performance of this fusion-based inferencing framework. (shrink)

Using the linearized Einstein gravitational field equations and the Maxwell field equations it is shown that the plane of polarization of an electromagnetic wave is rotated by the gravitational field created by the electromagnetic radiation of a ring laser. It is further shown that this gravitational Faraday effect shares many of the properties of the standard electromagnetic Faraday effect. An experimental arrangement is then suggested for the observation of this gravitational Faraday effect induced by the ring laser.

This paper examines several issues regarding deception in advertising. Some generally accepted definitions are considered and found to be inadequate. An alternative definition is proposed for legal/regulatory purposes and is related to a suggested definition of the term deception as it is used in everyday language. Based upon these definitions, suggestions are offered for detecting and regulating deception in advertising. This paper additionally considers the grounds for the generally held but largely unquestioned assumption that deceptive advertising is unethical. It is (...) argued that deceptive advertising can be shown to be morally objectionable, on the weak assumption that it is prima facie wrong to harm others. Finally, the implications of this analysis with respect to current regulation of deceptive advertising by the FTC are considered. (shrink)

This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of assessments of relative risk. To make this possible our approach draws on the fusion of both hard and soft data within a single decision support framework. Contextual data is (...) also taken into account, for example data about space weather effects, by drawing on the Space Domain Ontologies, a large system of ontologies designed to support all aspects of space situational awareness. The framework is coupled with a mathematical programming scheme that frames a mathematically optimal approach for decision support, providing a quantitative basis for ranking potential for collision across multiple satellite pairs. The goal is to provide the broadest possible information foundation for critical assessments of collision likelihood. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Contemplating the Beautiful: The Practical Importance of Theoretical Excellence in Aristotle’s EthicsJames L. Wood (bio)Aristotle, unlike plato, famously distinguishes φρόνησις from, practical from theoretical wisdom, in Book VI of the Nicomachean Ethics. He distinguishes them on the basis of both their objects and their psychic spheres: is the excellence or virtue (ἀρετή) of the scientific faculty, τὸ ἐπιστημονικόν, “by which we contemplate [θεωρου̑μεν] the sort of beings whose principles (...) [ἀρχαί] do not admit of being otherwise,” while φρόνησις is an excellence of the calculative faculty, τὸ λογιστικόν, by which we contemplate “the sort of beings that admit of being otherwise” (VI.1, 1139a6–8).1 Φρόνησις is skilled and experienced deliberation about human action and emotion, and in particular about “the sort of things that relate to (πρός) living well in general” (VI.5,1140a28); so φρόνησις guides right action, and as it turns out, directly entails excellence of character, ἠθική ἀρετή (VI.13, 1145a1–2)., on the other hand, while necessary for complete happiness (VI.12, 1144a1–6), “contemplates none of the things that make a human being happy” (VI.12, 1143b19–20), because it contemplates not changeable human affairs, circumstances, and actions, but eternal and unchanging realities (VI.6–7; X.7–8; cf. On the Soul, III.9, 432b26–433a1). Θεωρία, contemplation itself, is defined with reference to in Book X, where contemplation is made the basis of the highest human happiness as the excellent activity of intellect (νου̑ς) by which “beautiful and divine” realities are apprehended (X.7, 1177a15–18 and following). In contrast, the excellence of practical activity (both φρόνησις and ἠθική ἀρετή) is explicitly distinguished from the excellent theoretical activity of νου̑ς in θεωρία and relegated to a merely “secondary” importance (X.8, 1178a9 and following).2 [End Page 391]We might well conclude from this account that theoretical activity has nothing to do with practical activity, even if each is independently necessary for complete human happiness, and even if, as Aristotle says, practical excellence is somehow necessary to prepare the way for theoretical excellence (cf. VI.13, 1145a6–11). I wish to counter this impression, however, by showing that there is a theoretical dimension to excellent practical activity.3 More precisely, I will argue that theoretical activity contributes to practical excellence by furnishing the principles (ἀρχαί) of practical reasoning to the calculative faculty and the motivating end (τέλος) of action to the irrational-appetitive (τὸ; ἄλογον) part of the soul. The intellectual faculty that performs this theoretical activity is νου̑ς; the principles that νου̑ς apprehends are the first premises of ethical and political deliberation; and the τέλος that νου̑ς holds up to the appetitive soul as an orienting and motivating object is το καλόν.4 What distinguishes this activity from the theoretical activity that furnishes the principles of scientific reasoning (ἐπιστήμη) for the sake of knowledge is both the kinds of objects studied and the purpose of the study. One typically studies mathematics or astronomy in order to gain knowledge, not to act virtuously; however, one can certainly study the principles of human nature for the sake of virtuous action (as well as knowledge), as Aristotle himself does in the Ethics and other treatises (cf. II.2, 1103b27–29).5 Moreover, the theoretical study of the most “beautiful and divine” realities, described in Book X of the Ethics and Book XII of the Metaphysics, raises the possibility of a direct contribution of θεωρία at the highest levels to πρα̑ξις through the mediating activity of νου̑ς in the contemplation of the highest beauty and divinity.In what follows I will develop and defend these points through a close examination of Aristotle’s discussion of these concepts. My argument has three main parts. The first examines the role of thought in excellent action, the second brings out [End Page 392] the significance of το καλόν as the universal object of practical excellence, and the third argues in three subsections for the contribution in different ways of theoretical to practical excellence.1. The Dependence of Desire on Thought in Excellent ActionAs is clear from his concluding remarks in Book VI, where he declares that the possession of φρόνησις entails the possession of all the virtues of character (VI.13, 1145a1–2), Aristotle holds that the ἀρεταί of practical thought and character, φρόνησις and ἠθική ἀρετή, are interdependent and mutually implicating in virtuous choice and action. Thought needs desire in order to be practically effective... (shrink)

The concept of whole‐brain death is under attack again. Scholars are arguing that the concept of brain death per se—regardless of the focus on “higher,” “stem” or “whole”—is fundamentally flawed. These scholars have identified what they believe are serious discrepancies between the definition and criterion of brain death, and have pointed out that medical professionals and lay persons remain confused about its meaning. Yet whole‐brain death remains the standard for determining death in much of the Western world and its defenders (...) believe this concept best maps onto our everyday conception of death. (shrink)

In this interview, James L. McClelland responds to questions regarding connectionist models of cognition, a theory inspired by information processing in the brain. McClelland explains the distinction between symbolic and non-symbolic processing for a better understanding of mental processes. He argues that connectionist models can perform the computations which we know the brain can perform. In addition, he responds to several general questions on the perspectives of computational models of cognition.

Metaethical expressivism is typically characterised as the view that normative statements express desire-like attitudes instead of beliefs. However, in this paper I argue that expressivists should claim that normative statements express beliefs in normative propositions, and not merely in some deflationary sense but in a theoretically robust sense explicated by a theory of propositional attitudes. I first argue that this can be achieved by combining an interpretationist understanding of belief with a nonfactualist view of normative belief content. This results in (...) a view I call ‘interpretative expressivism’. I then argue that traditional arguments employed by expressivists that normative statements express noncognitive attitudes can just as well support the claim that normative statements express nonfactual or nonrepresentational beliefs. Finally, I argue that this view has a number of advantages to versions of expressivism that deny that normative statements express non-deflationary normative beliefs. (shrink)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

The distinction between the "permanent" (will not reverse) and "irreversible" (cannot reverse) cessation of functions is critical to understand the meaning of a determination of death using circulatory–respiratory tests. Physicians determining death test only for the permanent cessation of circulation and respiration because they know that irreversible cessation follows rapidly and inevitably once circulation no longer will restore itself spontaneously and will not be restored medically. Although most statutes of death stipulate irreversible cessation of circulatory and respiratory functions, the accepted (...) medical standard is their permanent cessation because permanence is a perfect surrogate indicator for irreversibility, and using it permits a more timely declaration. Therefore, patients properly declared dead in donation after circulatory death (DCD) protocols satisfy the requirements of death statutes and do not violate the dead donor rule. The acronym DCD should represent organ "donation after circulatory death" to clarify that the death standard is the permanent cessation of circulation, not heartbeat. Heart donation in DCD does not retroactively negate the donor's death determination because circulation has ceased permanently. (shrink)

This paper examines the general prospects for conceptual role expressivism, expressivist theories that embrace conceptual role semantics. It has two main aims. The first aim is to provide a general characterisation of the view. The second aim is to raise a challenge for the general view. The challenge is to explain why normative concepts are not a species of defective concepts, where defective concepts are those that cannot meaningfully embed and participate in genuine inference. After rejecting existing attempts to answer (...) the challenge, I propose an alternative solution. However, the solution leaves conceptual role expressivism a far less distinctive and interesting position than its proponents claim. I conclude that we should be sceptical about how much expressivists gain by appealing to conceptual role semantics. (shrink)

Abstract:Disturbing cases continue to be published of patients declared brain dead who later were found to have a few intact brain functions. We address the reasons for the mismatch between the whole-brain criterion and brain death tests, and suggest solutions. Many of the cases result from diagnostic errors in brain death determination. Others probably result from a tiny amount of residual blood flow to the brain despite intracranial circulatory arrest. Strategies to lessen the mismatch include improving brain death determination training (...) for physicians, mandating a test showing complete intracranial circulatory arrest, or revising the whole-brain criterion.

A combination of emerging life support technologies and entrenched organ donation practices are complicating the physician's task of determining death. On the one hand, technologies that support or replace ventilation and circulation may render the diagnosis of death ambiguous. On the other, transplantation of vital organs requires timely and accurate declaration of death of the donor to keep the organs as healthy as possible. These two factors have led to disagreements among physicians and scholars on the precise moment of death. (...) In this article, I suggest that the debate about exactly when a person dies can benefit from distinguishing the strict biological concept of death from the medical standards for determining human death, and I show how an appreciation of the difference between the permanent and irreversible cessation of circulation is helpful in understanding the reasons for the two approaches to determining when death should be declared.

Organ donation after the circulatory determination of death requires the permanent cessation of circulation while organ donation after the brain determination of death requires the irreversible cessation of brain functions. The unified brain-based determination of death connects the brain and circulatory death criteria for circulatory death determination in organ donation as follows: permanent cessation of systemic circulation causes permanent cessation of brain circulation which causes permanent cessation of brain perfusion which causes permanent cessation of brain function. The relevant circulation that (...) must cease in circulatory death determination is that to the brain. Eliminating brain circulation from the donor ECMO organ perfusion circuit in thoracoabdominal NRP protocols satisfies the unified brain-based determination of death but only if the complete cessation of brain circulation can be proved. Despite its medical and physiologic rationale, the unified brain-based determination of death remains inconsistent with the Uniform Determination of Death Act. (shrink)

The publicity surrounding the recent McMath and Muñoz cases has rekindled public interest in brain death: the familiar term for human death determination by showing the irreversible cessation of clinical brain functions. The concept of brain death was developed decades ago to permit withdrawal of therapy in hopeless cases and to permit organ donation. It has become widely established medical practice, and laws permit it in all U.S. jurisdictions. Brain death has a biophilosophical justification as a standard for determining human (...) death but remains poorly understood by the public and by health professionals. The current controversies over brain death are largely restricted to the academy, but some practitioners express ambivalence over whether brain death is equivalent to human death. Brain death remains an accepted and sound concept, but more work is necessary to establish its biophilosophical justification and to educate health professionals and the public. (shrink)

Expressivists about normative thought and discourse traditionally deny that there are nondeflationary normative propositions. However, it has recently been suggested that expressivists might avoid a number of problems by providing a theory of normative propositions compatible with expressivism. This paper explores the prospects for developing an expressivist theory of propositions within the framework of cognitive act theories of propositions. First, I argue that the only extant expressivist theory of cognitive propositions—Michael Ridge's ‘ecumenical expressivist’ theory—fails to explain identity conditions for normative (...) propositions. Second, I argue that this failure motivates a general constraint—the ‘unity requirement’—that any expressivist theory of propositions must provide a unified nonrepresentational explanation of that in virtue of which propositional attitudes have the content that they have. Third, I argue that conceptual role accounts of content provide a promising framework in which to develop an expressivist theory of cognitive propositions. (shrink)

The study of human intelligence was once dominated by symbolic approaches, but over the last 30 years an alternative approach has arisen. Symbols and processes that operate on them are often seen today as approximate characterizations of the emergent consequences of sub- or nonsymbolic processes, and a wide range of constructs in cognitive science can be understood as emergents. These include representational constructs (units, structures, rules), architectural constructs (central executive, declarative memory), and developmental processes and outcomes (stages, sensitive periods, neurocognitive (...) modules, developmental disorders). The greatest achievements of human cognition may be largely emergent phenomena. It remains a challenge for the future to learn more about how these greatest achievements arise and to emulate them in artificial systems. (shrink)

The definition of death is one of the oldest and most enduring problems in biophilosophy and bioethics. Serious controversies over formally defining death began with the invention of the positive-pressure mechanical ventilator in the 1950s. For the first time, physicians could maintain ventilation and, hence, circulation on patients who had sustained what had been previously lethal brain damage. Prior to the development of mechanical ventilators, brain injuries severe enough to induce apnea quickly progressed to cardiac arrest from hypoxemia. Before the (...) 1950s, the loss of spontaneous breathing and heartbeat were perfect predictors of death because the functioning of the brain and of all other organs ceased rapidly and nearly simultaneously thereafter, producing a unitary death phenomenon. In the pretechnological era, physicians and philosophers did not have to consider whether a human being who had lost certain “vital functions” but had retained others was alive, because such cases were technically impossible.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 35.2 (2002) 138-152 [Access article in PDF] Respecting the Rupture: Not Solving the Problem of Unity in Plato's Phaedrus James L. Kastely Plato's Phaedrus is a particularly instructive example of the double nature and status of rhetoric, for it embodies a tension at the heart of rhetoric. The first half of the dialogue presents three examples of rhetorical practice, while the second develops a theoretical (...) justification of rhetoric as an art. Thus, the dialogue would seem to offer a productive negotiation of the practice/theory tension. What makes the dialogue interesting, however, is the fact that this negotiation does not occur. The dialogue does not bring theory and practice into a harmonious relation, for there is a troubling discontinuity between its two halves, and rhetorical practice feels fractured. The exploration of eros that had occupied the first half of the dialogue is abandoned before the beginning of the second half, and then, following a logic that is at best associational, Socrates and Phaedrus explore the standards that should govern the practice of rhetoric. The infelicity of this transition raises a question: why did Plato structure the Phaedrus in such a way that it emphasized the dissonance between the two halves of the dialogue? To pose the question this way, however, is to go in a direction different from many of the best contemporary interpretations of the dialogue, which either argue that the dialogue is unified (Griswold 164) or suggest that the dissonance between its two halves reflects a shift in Plato's approach to philosophy (Kahn 373; Nehamas 352). In contrast, I will argue that the rupture in the dialogue is thematically purposive, for it points to an inescapable schism within rhetoric that makes rhetoric philosophically interesting.Socrates' second speech, his palinode to Eros, is a rhetorical tour de force that closes the first half of the dialogue. The importance of the palinode, however, is not limited to its role as an exemplary rhetorical performance, [End Page 138] for it also plays a crucial role in resolving the problem of erotic madness that organizes the intellectual drama of the first half. It would seem reasonable to expect that such an important and powerful moment in the dialogue would, at the very least, play a significant role in the philosophical discussion that composes the dialogue's second half. But that doesn't happen. While Socrates does refer to the palinode in his theoretical discussion of rhetoric, he makes little use of it, and, more important, he is silent on the subject of eros. Both the dramatic organization of the second half of the dialogue and its theoretical discussion cooperate to turn the rhetorical triumph of the palinode into a problem. Why has eros been abandoned as a philosophic topic, and what does this abandoning imply about the erotically grounded rhetoric that Socrates practiced and defended?To make matters worse, Socrates himself dismisses the palinode as a serious effort. He characterizes the speech as little more than a pleasant game, one that is not without value only because "these two certain forms (of gathering and dividing) were stated by chance" (265c). Far from viewing the palinode as possessing philosophical significance, Socrates appears to value it principally for its being a so-so example of a work of rhetoric that has been shaped by dialectic. While it is hard not to take Socrates' dismissal of the seriousness of the speech as partially disingenuous (just prior to his dismissal, he refers to the palinode as serious and reverent [265b]), he also does seem to mean what he says. Whether he is being straightforward or ironic does not finally matter because in either case the problem that occupies him and Phaedrus in the first half has disappeared from the dialogue. And that creates a problem: for if the philosophic issues of the first half of the dialogue drop out, then the dialogue is not coherent.This incoherence is especially troubling given Socrates' explicit endorsement of coherence as an important rhetorical value. In fact, when he begins his... (shrink)

Notwithstanding these wise pronouncements, my project here is to characterize the biological phenomenon of death of the higher animal species, such as vertebrates. My claim is that the formulation of “whole- brain death ” provides the most congruent map for our correct understanding of the concept of death. This essay builds upon the foundation my colleagues and I have laid since 1981 to characterize the concept of death and refine when this event occurs. Although our society's well-accepted program of multiple (...) organ procurement for transplantation requires the organ donor first to be dead, the concept of brain death is not merely a social contrivance to permit us to obtain the benefits of organ procurement. Rather, the concept of whole- brain death stands independently as the most accurate biological representation of the demise of the human organism. (shrink)
