In this paper, we explicitly point out the reasons why Special Relativity must be considered as the source of electron deep orbits, and dominates their behavior. We show that the cause is the quadratic form of the relativistic expression of energy, and this clearly appears when we explicitly develop the relativistic Schrödinger equation and compare it with the non-relativistic one.

Ethics committees are the most important practical instrument of clinical ethics in Belgium and fulfil three tasks: the ethical review of experimental protocols, advising on the ethical aspects of healthcare practice, and ethics consultation. In this article the authors examine the current situation of ethics committees in Belgium from the perspective of clinical ethics. Firstly, the most important steps which thus far have been taken in Belgium are examined. Secondly, recent opinion by the Belgian Advisory Committee on Bioethics with regard (...) to ethics committees is presented and the activities of Belgian ethics committees are discussed. Finally, the option to bring research ethics and clinical ethics under the roof of just one committee is criticised using a pragmatic and a methodological argument. Concomitantly, the authors build an argument in favour of the further development of ethics consultation. (shrink)

A major concern of public health authorities is to also encourage adults to be exposed to enriched environments during the pandemic lockdown, as was recently the case worldwide during the COVID-19 outbreak. Games for adults that require physical activity, known as exergames, offer opportunities here. In particular, the output of the gaming industry nowadays offers computer games with extended reality which combines real and virtual environments and refers to human-machine interactions generated by computers and wearable technologies. For example, playing the (...) game in front of a computer screen while standing or walking on a force plate or treadmill allows the user to react to certain infrastructural changes and obstacles within the virtual environment. Recent developments, optimization, and minimizations in wearable technology have produced wireless headsets and sensors that allow for unrestricted whole-body movement. This makes the virtual experience more immersive and provides the opportunity for greater engagement than traditional exercise. Currently, XR serves as an umbrella term for current immersive technologies as well as future realities that enhance the experience with features that produce new controllable environments. Overall, these technology-enhanced exergames challenge the adult user and modify the experience by increasing sensory stimulation and creating an environment where virtual and real elements interact. As a therapy, exergames can potentially create new environments and visualizations that may be more ecologically valid and thus simulate real activities of daily living that can be trained. Furthermore, by adding telemedicine features to the exergame, progress over time can be closely monitored and feedback provided, offering future opportunities for cognitive-motor assessment. To more optimally serve and challenge adults both physically and cognitively over time in future lockdowns, there is a need to provide long-term remote training and feedback. Particularly related to activities of daily living that create opportunities for effective and lasting rehabilitation for elderly and sufferers from chronic non-communicable diseases. The aim of the current review is to envision the remote training and monitoring of physical and cognitive aspects for adults with limited mobility, through the implementation of concurrent telehealth and exergame features using XR and wireless sensor technologies.

Because of their responsibilities for providing high-quality care, at times when they are continuously confronted with inherent professional and ethical challenges, nurses should meet high ethical standards of practice and conduct. Contrary to other countries, where codes of ethics for nurses are formulated to support those standards and to guide nurses’ professional practice, Belgian nurses do not have a formal code of ethics. Nevertheless, professional ethics is recognized as an important aspect in legal and other professional documents. The aim of (...) this article is to illustrate that codes of ethics are not the only professional documents reflecting nurses’ values, norms and responsibilities. Other documents can also set out professional nursing ethics, and as such replace codes of ethics. (shrink)

The current debate on euthanasia in the Lowlands is a perfect examplification of the predominance of the principle of respect for autonomy in present-day medical-ethical decisionmaking. The aim of this article is the exploration of the more fundamental philosophical issues concerning the current status of autonomy in medical ethics. The starting point for this exploration is an analysis of the principle of respect for autonomy. The authors argue that the view on autonomy in contemporary bioethical discussions is more related to (...) the Millian understanding of autonomy rather than to Kant’s conception of respect for autonomy. The uncompromising veneration of personal autonomy and the subsequent view on the human self as unencumbered is placed under critique because this portrayal of the human person is rather unreal especially in medical-ethical decisionmaking where the fragility of human life is at stake. Furthermore, extending the claims of autonomy risks to undermine the public sphere. The defence of the principle of autonomy is taken on by the quality-of-life ethic that values human life because of its qualities. Being capable of making autonomous decisions is one of this main qualities. By this, the quality-of-life approach runs counter to an idea that is deeply ingrained in medicine, viz. the sanctity of human life that holds both the inviolability and the equal value of human life. These two approaches can, however, be integrated in Christian ethics by adopting a view on quality-of-life judgements in which the proportionality of benefits and burdens has a pivotal function. To conclude this article, the authors argue for a non-absolutist account of autonomy based on two modes of decentrement of the human self: the fundamental passivity at the core of the human person and the intersubjectivity of the human existence.

Belgium is the second country in the world that decriminalized euthanasia. On May 28, 2002 the Belgian Parliament approved the bill on euthanasia. With this approval, the political majority in the Belgian Parliament took a momentous decision concerning how we as a society deal with life and death.For many, euthanasia holds a promise. They take euthanasia literally as the ‘good death’. Others identify the recourse to euthanasia as a symptom of a ‘culture of death’. Given the importance of legislation on (...) euthanasia, an ethical reflection on the rationale and course of the Belgian debate on euthanasia urges itself.It is the aim of this contribution to shed light on the Belgian debate on euthanasia from an ethical perspective. The focus is thus rather on the arguments underlying the debate and their ethical assessment which implies the clarification of the values involved and the options made in the eventual legislation.To understand how and why the Belgian debate evolved as it did resulting in the final vote on the law on euthanasia, two reports of the Belgian Federal Advisory Committee on Bioethics are cardinal: the Advice n° 1 concerning the Desirability of Legislation on Euthanasia and the Advice n° 9 concerning the Termination of Life of Incompetent Patients .These two reports expressed the opinions and moral viewpoints present in Belgian society. After the presentation of the two reports and their underlying axiology we will examine what their relationship is with the eventual law on euthanasia which was the tailpiece of five years of public and political debate.In this examination, the pivotal question will be whether the legislature has succeeded in doing justice to the different moral viewpoints and the tendencies to a moral consensus that were formulated in the two reports.

Belgium and the Netherlands are the first countries in the world that have legalized euthanasia and assisted suicide. Since September 23, 2002, Belgian physicians can perform an act of euthanasia without at the same time performing a criminal act. In the Netherlands, the act on euthanasia went into force already on April 1, 2002. This special issue of Ethical Perspectives on ‘Euthanasia in the Low Countries’ offers a forum for critical dialogue on the different aspects of this new legal situation (...) in Belgium and the Netherlands.First, the legal situation will be introduced. In his contribution, Herman Nys makes a careful comparison of both laws. In spite of the fact that Belgium and the Netherlands are the first countries in the world that legalized euthanasia, the differences between the Belgian and Dutch law are fundamental. As Nys indicates, the scope of the Dutch law is more specified since it explicitly includes physician-assisted suicide while it remains unclear whether the Belgian act is also applicable in cases of assisted suicide. There are also fundamental differences regarding the persons regulated by the law, the health condition of the patient, the obligations of the physician with respect to the request and the health status of the patient, and the notification procedure.However, not only are there fundamental differences between Belgium and the Netherlands on the level of the law. Also the public debate and the values underlying the the debate show dissimilarities. In the Netherlands this debate took more than twenty years and the subsequent law on euthanasia reflected an existing medical practice. In Belgium, on the contrary, the parliament came to vote on the euthanasia law after only half a decade of debate. In our contribution , we identify the right to autonomy understood as ‘self-possession’ as the central value in the Belgian debate. Guy Widdershoven asserts that the moral basis of euthanasia in the Netherlands is different. He argues that the Dutch debate — and by now Dutch practice — cannot be reduced to the "principlist canon of autonomy and beneficence". Instead, the values of responsibility, deliberation and care are claimed to be central to Dutch euthanasia practice.In his contribution, Daniel Sulmasy offers an exhaustive analysis of the notion of dignity that constantly arises in the debate on euthanasia. For Christian churches and Catholic healthcare institutions, the recent legalization of euthanasia and assisted suicide is at least challenging. Jan Jans describes the way in which the main Christian churches in Belgium and the Netherlands engaged in the debate and reacted to the eventual legalization. Chris Gastmans presents the view of the Flemish Association of Catholic Healthcare Institutions.Law-making with respect to euthanasia is one thing. Bringing the law into practice is somewhat different. The question arises to what extent the new legal situation will bear upon the medical practice. Particularly, the responses of physicians are difficult to assess in advance. Physicians face the dilemma to report or not to report. They can take up their responsibility and report their practices of euthanasia, thereby exposing themselves to critical examination and possibly criminal prosecution. On the other hand, the physician can opt for safety and decide not to report his involvement in one of his patients’ euthanasia. In the latter case, the introduction of new legislation would have missed the mark. To this day, the only available data with regard to physicians’ reactions to an established legal framework wherein euthanasia is legalized come from the Netherlands. In his contribution, Albert Klijn presents the reactions of Dutch physicians to the new legal situation in their country and, particularly, the performance of their duty to report cases of euthanasia. Since the vote on the law in 2000 and the establishment of ‘regional review committees for termination of life on request and assisted suicide’ in 2001, the reports of euthanasia have declined. Klijn considers two possible explanations. On the one hand, there is insecurity about how the newly established regional review committees will evaluate physician' reports. On the other hand, the increased investment in research on palliative care and the availability of palliative sedation are held responsible for the drop in reported cases.This very interesting suggestion by Klijn needs further clarification. Therefore, the meaning of palliative care and the possibility of palliative sedation are elaborated in the contribution of Bert Broeckaert and Rien Janssens.With this special issue on ‘Euthanasia in the Low Countries’ we hope to have answered the numerous requests for further information on the Belgian and Dutch situation. Data, clarification and critical review may shed more light on the development of a practice, which some still consider as non-medical behaviour. This issue may therefore also function as a catalyst for further medical, ethical and legal debate. (shrink)

The purpose of this article is to clarify both the role of nurses in ethics meetings and the way in which ethics meetings can function as a catalyst for good nursing care. The thoughts presented are practice based; they arose from our practical experiences as nurses and ethicists with ethics meetings in health care organizations in Belgium. Our reflections are written from the perspective of the nurse in the field who is participating in (inter)professional ethical dialogue. First, the difficulties that (...) nurses experience while participating in ethics meetings are described. Then the possibilities for support of nurses in their ethical responsibility are explored.

PART 9: GRAVITY'S ETHICSThis isn't a hospital! It's an insane asylum! And it's your fault! Shaking her head lightly, Doctor Van Tintelen leaves the room and softly closes the door. Empathy streaming through her veins, she never gets used to the unpolished grief of a patient she has to tell of inevitable death, never. She thinks, “There should be pipes to drain the tears in every room, or at least rinsing basins for grief. What a job.” The crying is that (...) of the sisters Barrio. Miranda and Monica are twins who always refer to themselves as M&M. Though Monica cries the hardest, it is Miranda who was just told that her breast cancer has spread into her liver. No more treatment available.“Don't cry, Monica, I took the risk purposely. We both knew breast cancer runs in our family. You had the test, I didn't.”“And now you see the result, Miranda, you are going to die. We aren't even fifty yet. Damn.” The irony is that the clock in the room doesn't work, its pointers silent and stiff.“Do you really think you are better off? I've never completely understood why you had the preventive double mastectomy.”“I have never felt less of a woman. You know that.”“I know, but some men felt differently about it.”The remark hurts Monica almost physically, and Miranda apologises immediately. “Sorry, sweetheart, I shouldn't have said that. The sisters embrace for the hundredth time.”“Maybe I was too much of a coward,” Miranda says, resigned, “or too proud of my breasts.” For a second she lifts the big breasts sadly with her hands. Cynically: “After all, they were my trumps in eroland.”“A coward? You? How about me?” Monica seems to calm down somewhat. “I was too afraid of the continual fear …. (shrink)

Part 10: The very old man and the sea of tears‘There is no time to waste, then, is there?' ‘He needs to be treated.’‘But he is 79 years old.’Two doctors in conflict. As happens often. The subject of the conversation is Mr Tyson, admitted to the hospital because of an aneurysm in his abdomen. Sarah Walters said ‘treat’. ‘Nonsense, too old, too risky’ is the opinion of Dr Jones. The squabble continues.Sarah: ‘So what? Does old age exclude you from society? (...) Of course we have to treat him.’‘But the investment will only last for a few years, and think of the risks, he may die from the operation. He should go home and, well, live what there is to live.’She shakes her head, her hair giving her a red aura. ‘I think he ought to have the operation.’‘I think it would be best if he should accept that time is running out, that life is finite, the whole existential rigmarole, et cetera.’‘Quite presumptuous of you to think he has not accepted that. Why? Just because he is old and did not kill himself?’ Sarah is indignant. ‘If he had done just that, we would have lamented about how we do not take care of our elderly, that society doesn't care, and that certainly there is no right to die unless your situation is totally hopeless and you're in a lot of pain. It doesn't make sense; in public health one does everything to increase life expectancy. Countries are proudly comparing themselves on the life expectancy list: mine is longer than yours. We worry because people have these unhealthy lifestyles, they are obese, they smoke, they get no exercise and they live a couch potato life. And then, lo and behold, they do grow old, in fact, and we go: …. (shrink)

More than 20 cameras focus on him, and one journalist yells “there he is!” Even Gordon is not used to that much attention, but vanity is a speedy advisor. Within seconds he has clad himself in the aura of important person, and knowledgeable ethicist, even if (...) he has no idea what that many journalists expect from him at precisely this moment. Particularly when he has little time, preparing for the world conference on bioethics in Singapore. Then a wave of disappointment hits the gathered gossip-mongering press. The floodlights are turned off, microphones are lowered, the buzzing quiets down.“Guys, this is not Testosterone Tony.”This Tony, the athlete who participated in the Olympic Games in Beijing, at that moment leaves the hospital by a back door, far away from the paparazzi. The armoured car of his sponsor Nanosock disappears from sight softly humming and brings him to a private clinic where he will be pampered and detoxified. His career in sports is over, but his reputation can certainly sell sports socks with nanofibres against sweaty feet. The only price he has to pay is to admit he has sweaty feet, not true, but a small price to pay considering the alternatives. In front of the hospital the disappointed and somewhat offended Gordon tries to save his ego and asks the journalists:“Maybe I can be of help? Do you want an ethical analysis of Testosterone Tony and enhancing evolution? My name is Gordon Mc….” Nobody listens, nobody reacts.A day later. Nurses Jake and Gwen return from the medication round.

Health care systems have four objectives: (1) the provision of the best possible care for all; while (2) guaranteeing equal access to health care; (3) maintaining freedom of choice for health care providers and patients; and (4) controlling the costs. In an ideal world with abundant resources the realization of these objectives would pose no significant problems. However, any actual health care system will need a trade-off between the different objectives because resources are limited. In Setting Limits Fairly, Norman Daniels (...) and James Sabin investigate how limits can be set in the allocation of health care resources. (shrink)

A precise formulation of the structure of modern evolutionary theory has proved elusive. In this paper, I introduce and develop a formal approach to the structure of population genetics, evolutionary theory's most developed sub-theory. Under the semantic approach, used as a framework in this paper, presenting a theory consists in presenting a related family of models. I offer general guidelines and examples for the classification of population genetics models; the defining features of the models are taken to be their state (...) spaces, parameters, and laws. The suggestions regarding the various aspects of the characterization of population genetics models provide an outline for further detailed research. (shrink)

The paper explores the promise of ethical codes as a means to control unethical behavior in business. After a review of arguments for ethical codes from outside the business system, the paper outlines the arguments for codes from inside the business system at the level of the industry, firm and individual executive.The paper then discusses the problems of code design — the dilemma between specific practices and general precepts — and offers a model for a thoroughgoing code. This is followed (...) by a discussion of the problems of promulgation and code enforcement. (shrink)

A structure which generalizes formulas by including substitution terms is used to represent proofs in classical logic. These structures, called expansion trees, can be most easily understood as describing a tautologous substitution instance of a theorem. They also provide a computationally useful representation of classical proofs as first-class values. As values they are compact and can easily be manipulated and transformed. For example, we present an explicit transformations between expansion tree proofs and cut-free sequential proofs. A theorem prover which represents (...) proofs using expansion trees can use this transformation to present its proofs in more human-readable form. Also a very simple computation on expansion trees can transform them into Craig-style linear reasoning and into interpolants when they exist. We have chosen a sublogic of the Simple Theory of Types for our classical logic because it elegantly represents substitutions at all finite types through the use of the typed -calculus. Since all the proof-theoretic results we shall study depend heavily on properties of substitutions, using this logic has allowed us to strengthen and extend prior results: we are able to prove a strengthen form of the firstorder interpolation theorem as well as provide a correct description of Skolem functions and the Herbrand Universe. The latter are not straightforward generalization of their first-order definitions. (shrink)

The conflation of two fundamentally distinct issues has generated serious confusion in the philosophical and biological literature concerning the units of selection. The question of how a unit of selection of defined, theoretically, is rarely distinguished from the question of how to determine the empirical accuracy of claims--either specific or general--concerning which unit(s) is undergoing selection processes. In this paper, I begin by refining a definition of the unit of selection, first presented in the philosophical literature by William Wimsatt, which (...) is grounded in the structure of natural selection models. I then explore the implications of this structural definition for empirical evaluation of claims about units of selection. I consider criticisms of this view presented by Elliott Sober--criticisms taken by some (for example, Mayo and Gilinsky 1987) to provide definitive damage to the structuralist account. I shall show that Sober has misinterpreted the structuralist views; he knocks down a straw man in order to motivate his own causal account. Furthermore, I shall argue, Sober's causal account is dependent on the structuralist account that he rejects. I conclude by indicating how the refined structural definition can clarify which sorts of empirical evidence could be brought to bear on a controversial case involving units of selection. (shrink)

Probably to most students of Moral Philosophy there comes a time when they feel a vague sense of dissatisfaction with the whole subject. And the sense of dissatisfaction tends to grow rather than to diminish. It is not so much that the positions, and still more the arguments, of particular thinkers seem unconvincing, though this is true. It is rather that the aim of the subject becomes increasingly obscure. "What," it is asked, "are we really going to learn by Moral (...) Philosophy?" "What are books on Moral Philosophy really trying to show, and when their aim is clear, why are they so unconvincing and artificial?" And again: "Why is it so difficult to substitute anything better?" Personally, I have been led by growing dissatisfaction of this kind to wonder whether the reason may not be that the subject, at any rate as usually understood, consists in the attempt to answer an improper question. And in this article, I shall venture to contend that the existence of the whole subject, as usually understood, rests on a mistake, and on a mistake parallel to that on which rests, as I think, the subject usually called the Theory of Knowledge.

A key concern of global ethics is the equitable distribution of benefits and burdens amongst persons belonging to different populations. Until recently, the philosophical literature on global distribution was dominated by the question of how benefits and burdens should be divided amongst contemporaries. Recent years, however, have seen an increase in research on the scope and content of our duties to future generations. This has led to a number of innovative attempts to extend principles of distribution across time while retaining (...) a focus on the entitlements of the existing poor. In this article, I examine a key aspect of intergenerational justice, namely, the appropriate 'pattern' of well-being that should be obtained across generations. With the aid of research into the impacts of global climate change, I evaluate a number of rival accounts of the pattern of justice and go on to explore the merits of a 'global sufficientarian' ethic, which holds that as many persons as possible should enjoy a satisfactory level of well-being regardless of when or where they live.

The vast majority of contributions to the literature on spirituality in nursing make extravagant claims about transcendence, eternity, the numinous, higher powers, higher levels of existence, invisible forces, cosmic unity, the essence of humanity, or other supernatural concepts. Typically, these assertions are made without the support of argument or evidence; and, as a consequence, alternative ways of theorizing ‘spirituality’ have been closed off, while the lack of consistent scholarship has turned the topic into a metaphysical backwater. In this paper, I (...) adopt a different premise, rejecting unsupported claims, and surveying the ‘spirituality’ terrain from a naturalistic and reductionist perspective. I argue that, if we rid ourselves of non‐naturalistic assumptions, we will discover theoretical and clinical resources in health psychology, social psychology, neuropsychology, and pharmacopsychology – resources which confirm that it is possible to conceptualize the study of existential concerns, and how health professionals might respond to them, in a properly scientific manner. In order to illustrate the potential usefulness of these resources, I will take palliative care as an example. (shrink)

The study of the autonomic nervous system (ANS) function has shown to provide useful indicators for risk stratification and early detection on a variety of cardiovascular pathologies. However, data gathered during different tests of the ANS are difficult to analyse, mainly due to the complex mechanisms involved in the autonomic regulation of the cardiovascular system (CVS). Although model-based analysis of ANS data has been already proposed as a way to cope with this complexity, only a few models coupling the main (...) elements involved have been presented in the literature. In this paper, a new model of the CVS, representing the ventricles, the circulatory system and the regulation of the CVS activity by the ANS, is presented. The models of the vascular system and the ventricular activity have been developed using the Bond Graph formalism, as it proposes a unified representation for all energetic domains, facilitating the integration of mechanic and hydraulic phenomena. In order to take into account the electro-mechanical behaviour of both ventricles, an electrophysiologic model of the cardiac action potential, represented by a set of ordinary differential equations, has been integrated. The short-term ANS regulation of heart rate, cardiac contractility and peripheral vasoconstriction is represented by means of continuous transfer functions. These models, represented in different continuous formalisms, are coupled by using a multi-formalism simulation library. Results are presented for two different autonomic tests, namely the Tilt Test and the Valsalva Manoeuvre, by comparing real and simulated signals. (shrink)

A proof of ‘correctness’ for a mathematical algorithm cannot be relevant to executions of a program based on that algorithm because both the algorithm and the proof are based on assumptions that do not hold for computations carried out by real-world computers. Thus, proving the ‘correctness’ of an algorithm cannot establish the trustworthiness of programs based on that algorithm. Despite the (deceptive) sameness of the notations used to represent them, the transformation of an algorithm into an executable program is a (...) wrenching metamorphosis that changes a mathematical abstraction into a prescription for concrete actions to be taken by real computers. Therefore, it is verification of program executions (processes) that is needed, not of program texts that are merely the scripts for those processes. In this view, verification is the empirical investigation of: (a) the behavior that programs invoke in a computer system and (b) the larger context in which that behavior occurs. Here, deduction can play no more, and no less, a role than it does in the empirical sciences. (shrink)

Work in the setting of the recursively enumerable sets and their Turing degrees. A set X is low if X', its Turning jump, is recursive in $\varnothing'$ and high if X' computes $\varnothing''$ . Attempting to find a property between being low and being recursive, Bickford and Mills produced the following definition. W is deep, if for each recursively enumerable set A, the jump of $A \bigoplus W$ is recursive in the jump of A. We prove that there are no (...) deep degrees other than the recursive one. Given a set W, we enumerate a set A and approximate its jump. The construction of A is governed by strategies, indexed by the Turning functionals Φ. Simplifying the situation, a typical strategy converts a failure to recursively compute W into a constraint on the enumeration of A, so that $(W \bigoplus A)'$ is forced to disagree with Φ(-; A'). The conversion has some ambiguity; in particular, A cannot be found uniformly from W. We also show that there is a "moderately" deep degree: There is a low nonzero degree whose join with any other low degree is not high. (shrink)

In a recent series of articles, and in his latest book, James Cornman has proposed and defended a definition of ‘observation term’. The original definition appeared in [3]; in [4] Cornman defended this definition against some criticisms offered by P. K. Machamer, and also revised it somewhat; the revised definition is restated in [2] and used there in Cornman's discussion of the identity theory of the mind. Finally, in [1], Cornman again invokes his definition in defending scientific instrumentalism, and defends (...) it against various generalized attacks on the very possibility of drawing a distinction between observational and theoretical terms which will do the sort of work Cornman wants it to do.

Suppose that entities composed of two distinct components can be qualitatively ordered in two ways, such that each ordering relation satisfies the axioms of conjoint measurement. Without further assumptions nothing can be said about the relation between the pair of numerical scales constructed for each component. Axioms are stated that relate the two measurement theories, and that are sufficient to establish that the two conjoint scales on each component are linearly related.

After defining integrity capacity and framing it as part of a strategic resource model of sustainable global competitive advantage, the stakeholder costs of integrity capacity neglect are delineated.

Finally, the authors (...) recommend two leadership practices to build competence in business leaders to enhance integrity capacity as an organizational strategic asset. (shrink)

Scientists generally record their laboratory activities and experimental results in notebooks, from which they construct scientific papers. The Johns Hopkins physiologist William Henry Howell kept a laboratory notebook from 1913 to 1914, in which he recorded experiments on the blood clotting factor prothrombin. In 1914 he published a paper using this notebook, to justify his theory of prothrombin activation. Howell's paper is reconstructed, in terms of its narrative and argument elements, from the laboratory activities and experimental results recorded in the (...) notebook. This reconstruction reveals an intimate connection between the two texts and the process by which Howell constructed a scientific paper. The generation of scientific knowledge by Howell is then evaluated, especially in terms of theory formation and justification. (shrink)

Deterministic models in population dynamics often are really approximations to stochastic models, justified by an appeal to the law of large numbers. It is proposed to call such models pseudodeterministic. Four questions are discussed in this article: (1) What errors may be made by equating deterministically predicted values to expectations? (2) When, and in what sense, may numbers be assumed to be large? (3) How large are the variances, coefficients of variations, etc., as assigned to the variables in the stochastic (...) versions of the models? (4) What role may pseudodeterministic models play in empirical research, where problems of statistical reliability arise?As an example, a modified Nicholson-Bailey model of the interaction between insect parasitoids and their hosts is discussed; the modification consists of assigning a random (density-independent) mortality to the parasitoid population. A stochastic version of this model is discussed. The expectation of the final host density is compared with the value computed from the deterministic model. The latter value is systematically lower than the former. The magnitude of the difference depends on parameter values. The variability to be expected with the stochastic model is characterized by the coefficient of variation of the final host density; its dependence on parameter values and initial conditions is discussed. It is concluded that it is worthwhile in practical applications to estimate parasitoid mortality, and that the coefficient of variation in real situations may be far from negligible. (shrink)

[A. W. Moore] Criteria of ineffability are presented which, it is claimed, preclude the possibility of truths that are ineffable, but not the possibility of other things that are ineffable—not even the possibility of other things that are non-trivially ineffable. Specifically, they do not preclude the possibility of states of understanding that are ineffable. This, it is argued, allows for a reappraisal of the dispute between those who adopt a traditional reading of Wittgenstein’s Tractatus and those who adopt the new (...) reading recently championed by Cora Diamond, James Conant, and others. By maintaining that what the nonsense in the Tractatus is supposed to convey is ineffable understanding, rather than ineffable truth, we can do considerable justice to each of these readings. We can also do considerable justice to the Tractatus. /// [Peter Sullivan] Moore proposes to cut between 'traditional' and 'new' approaches to the Tractatus, suggesting that Wittgenstein's intention is to convey, through the knowing use of nonsense, ineffable understanding. I argue, first, that there is indeed room for a proposal of Moore's general kind. Secondly, though, I question whether Moore's actual proposal is not more in tune with Wittgenstein's later thought than with the attitude of the Tractatus. (shrink)

This paper discusses the vast continuum between the letter of the law (legality) and the spirit of the law (ethics or morality). Further, the authors review the fiduciary duties owed by the firm to its various publics. These aspects must be considered in developing a corporate code of ethics. The underlying qualitative characteristics of a code include clarity, comprehensiveness and enforceability. While ethics is indigenous to a society, every code of ethics will necessarily reflect the corporate culture from which that (...) code stems and be responsive to the innumerable situations for which it was created. Several examples have been provided to illustrate the ease of applicability of these concepts. (shrink)

Many nonanthropocentric environmental ethicists subscribe to a ``principle-ist'''' approach to moral argument, whereby specific natural resource and environmental policy judgments are deduced from the prior articulation of a general moral principle. More often than not, this principle is one requiring the promotion of the intrinsic value of nonhuman nature. Yet there are several problems with this method of moral reasoning, including the short-circuiting of reflective inquiry and the disregard of the complex nature of specific environmental problems and policy arguments. In (...) the present paper, we advance an alternative, pragmatic contextualist approach to environmental ethics, one grounded in the moral theory of John Dewey. We present the results of an empirical study of public environmental ethics and natural resource management attitudes to support our position, and we conclude with a few recommendations for future inquiry in the field of environmental ethics.

I begin with Kant's notion of a maxim and consider the role which this notion plays in Kant's formulations of the fundamental categorical imperative. This raises the question of what a maxim is, and why there is not the same requirement for resolutions of other kinds to be universalizable. Drawing on Bernard Williams' notion of a thick ethical concept, I proffer an answer to this question which is intended neither in a spirit of simple exegesis nor as a straightforward exercise (...) in moral philosophy but as something that is poised somewhere between the two. My aim is to provide a kind of rational reconstruction of Kant. In the final section of the essay, I argue that this reconstruction, while it manages to salvage something distinctively Kantian, also does justice to the relativism involved in what J. L. Mackie calls 'people's adherence to and participation in different ways of life'. (shrink)

Kendall's (1956) approach to the general epidemic is generalized by dropping the assumptions of constant infectivity and random recovery or death of ill individuals. A great deal of attention is paid to the biological background and the heuristics of the model formulation. Some new results are: (l) the derivation of Kermack's and McKendrick's integral equation from what seems to be the most general set of assumptions in section 2.2, (2) the use of Kermack's and McKendrick's final value equation to arrive (...) at a finite time version of the threshold theorem for the general case, comparable to that for the case of only one Markovian state of illness in section 2.5, (3) the analysis of the behaviour of the solutions of the integral equation when the starting infection approaches zero in section 2.7, (4) the derivation of the probability structure of a general branching process, after conditioning on extinction in section 3.6, (5) the statement of the generalized versions of Kendall's ideas in the form of precise limit conjectures in section 4, (6) the derivation of a closed expression for the limit epidemic resulting from (3) in appendix 4.

Few disputes in the annals of US environmentalism enjoy the pedigree of the conservation-preservation debate. Yet, although many scholars have written extensively on the meaning and history of conservation and preservation in American environmental thought and practice, the resonance of these concepts outside the academic literature has not been sufficiently examined. Given the significance of the ideals of conservation and preservation in the justification of environmental policy and management, however, we believe that a more detailed analysis of the real-world use (...) and understanding of these ideas is needed. In this paper, we describe the results of a qualitative, semantic study of the concepts of conservation and preservation undertaken in the context of the Chattahoochee National Forest (CNF), located in northern Georgia (USA). Thirty in-depth interviews were conducted with scientists and north Georgia residents either interested or involved in the future management of the forest. Respondents were asked to define conservation and preservation in their own words and to indicate which approach they felt was more appropriate for the management of the CNF. Qualitative content analysis was used to elicit a set of recurring themes for each foundational concept. Taken together, these themes help to flesh out the meaning of conservation and preservation for citizens and scientists today, and illustrate the evolving nature of two of the more significant and venerable ideas animating US environmental policy and management.

Working in Z + KP, we give a new proof that the class of hereditarily finite sets cannot be proved to be a set in Zermelo set theory, extend the method to establish other failures of replacement, and exhibit a formula Φ(λ, a) such that for any sequence $\langle A_{\lambda} \mid \lambda \text{a limit ordinal} \rangle$ where for each $\lambda, A_{\lambda} \subseteq ^{\lambda}2$ , there is a supertransitive inner model of Zermelo containing all ordinals in which for every λ A (...) λ = {α ∣Φ(λ, a)}.

This essay involves exploration of certain repercussions of Bernard Williams’ view that there is, in Wittgenstein’s later work, a transcendental idealism akin to that found in the Tractatus—sharing with it the feature that it cannot be satisfactorily stated. It is argued that, if Williams is right, then Wittgenstein’s later work precludes a philosophically substantial theory of meaning; for such a theory would force us to try to state the idealism. In a postscript written for the reprint of the essay, reasons (...) are given for thinking that Williams is not right: Wittgenstein’s later work actually helps us to repudiate as ill-conceived all those questions whose answers invite us to embrace any such idealism. But the main thesis of the essay remains intact. Indeed the idea that Wittgenstein’s later work precludes a philosophically substantial theory of meaning is reinforced. (shrink)

Philosophers of biology, along with everyone else, generally perceive life to fall into two broad categories, the microbes and macrobes, and then pay most of their attention to the latter. ‘Macrobe’ is the word we propose for larger life forms, and we use it as part of an argument for microbial equality. We suggest that taking more notice of microbes – the dominant life form on the planet, both now and throughout evolutionary history – will transform some of the philosophy (...) of biology’s standard ideas on ontology, evolution, taxonomy and biodiversity. We set out a number of recent developments in microbiology – including biofilm formation, chemotaxis, quorum sensing and gene transfer – that highlight microbial capacities for cooperation and communication and break down conventional thinking that microbes are solely or primarily single-celled organisms. These insights also bring new perspectives to the levels of selection debate, as well as to discussions of the evolution and nature of multicellularity, and to neo-Darwinian understandings of evolutionary mechanisms. We show how these revisions lead to further complications for microbial classification and the philosophies of systematics and biodiversity. Incorporating microbial insights into the philosophy of biology will challenge many of its assumptions, but also give greater scope and depth to its investigations. (shrink)

The ‘music appreciation as contemplation’ paradigm of traditional aesthetics and music education assumes that music exists to be contemplated for itself. The resulting distantiation of music and music education from life creates a legitimation crisis for music education. Failing to make a noteworthy musical difference for society, a politics of advocacy attempts to justify music education. Praxial theories of music, instead, see music as pragmatically social in origin, meaning, and value. A praxial approach to music education stresses that appreciation is (...) seen in use; thus, it seeks to ‘make a difference’ that students and society find musically noteworthy. (shrink)
