Great Expectations: Cost-Utility Models as Decision Criteria

One of the more puzzling features of published claims for cost-effectiveness is the popularity of claims presented in terms of quality adjusted life years (QALYs). Despite the popularity of QALYs as the ‘gold standard’ outcome measures among academic audiences, professional groups and a number of single payer health care systems, there is no evidence to suggest that cost-per-QALY based claims have ever been assessed, either through experimentation or observation, to support formulary decisions. In part this stems from the fact that cost-per-QALY claims are typically not expressed in evaluable terms; it also stems from the fact that, despite the plethora of QALY publications, QALYs are not collected on a regular basis by any health care system as part of administrative claims or electronic medical records. In the US QALYs have typically been ignored by health care decision makers. Given this, the continuing popularity of utility-based measures for studies published in the leading pharmacoeconomics journals is difficult to understand. One possible explanation is that those promoting QALY claims are locked into a relativist position that defends the publication of nontestable product claims. A position that is reinforced by recommendations from ‘peer organizations’ such as the Academy of Managed Care Pharmacy (AMCP) in their promotion of their Format for Formulary Submission standards which support the role of lifetime cost-per-QALY modeled imaginary worlds or thought experiments. Another explanation is that QALYs have been taken at face value with little though given to how they might be implemented to support both initial formulary decisions as well as ongoing disease area therapeutic class reviews. The purpose of this review is to put the case that the continued emphasis on cost-per-QALY claims has no practical benefit in formulary decision making.

The ‘saving lie’ and the saving truth

At the conclusion of Conrad’s Heart of Darkness, Marlow lies about the dying words of the grieving fiancée’s villainous lover, Kurtz. He relates what her tearful questioning shows him she longs to hear, acting from fear of destroying her faith in Kurtz’s love for her. In this context I consider aspects of the absolutist and relativist positions regarding truth and lies. I also discuss whether absolute truth is obligatory in every situation or whether, as I conclude, a lie spoken in compassion for others’ feelings, despite the moral ambiguity, can be a loving act honoured by God in that situation.

Relativistic dynamics, Green function and pseudodifferential operators

The central role played by pseudodifferential operators in relativistic dynamics is known very well. In this work, operators like the Schrodinger one (e.g., square root) are treated from the point of view of the non-local pseudodifferential Green functions. Starting from the explicit construction of the Green (semigroup) theoretical kernel, a theorem linking the integrability conditions and their dependence on the spacetime dimensions is given. Relativistic wave equations with arbitrary spin and the causality problem are discussed with the algebraic interpretation of the radical operator and their relation with coherent and squeezed states. Also we perform by means of pure theoretical procedures (based in physical concepts and symmetry) the relativistic position operator which satisfies the conditions of integrability: it is a non-local, Lorentz invariant and does not have the same problems as the “local”position operator proposed by Newton and Wigner. Physical examples, as zitterbewegung and rogue waves, are presented and deeply analyzed in this theoretical framework.

Against Relativism. The Importance of Truth in the Ethics of St. John Paul II

The main aim of the paper is the analysis and critique of axiological relativism, typical of contemporary Western culture. Its supporters deny the objective status of moral norms and values. Axiological relativism leads to moral indifference based on blurring the difference between good and evil, and negating the belief that human action may be morally better or worse. I present the anti­‑relativistic position of St. John Paul II, particularly in relation to the truth, understood as a cognitive and moral value. According to the Pope, a civilization based on the belief of the relative nature of good and evil leads to widespread hypocrisy and is destined to a slow decline.

Relativistic causality and position space renormalization

The paper gives a historical survey of the causal position space renormalization with a special attention to the role of Raymond Stora in the development of this subject. Renormalization is reduced to subtracting the pole term in analytically regularized primitively divergent Feynman amplitudes. The identification of residues with “quantum periods” and their relation to recent developments in number theory are emphasized. We demonstrate the possibility of integration over internal vertices (that requires control over the infrared behavior) in the case of the massless φ4 theory and display the dilation and the conformal anomaly.

Between relativism and pluralism: Philosophical and political relativism in Feyerabend's late work

Relativism is one of the most problematic terms associated with philosophical discourse, with Feyerabend considered among the most important twentieth century theorists subscribing to it. This paper provides a detailed overview of relativist positions advanced in Feyerabend's mid-to-late work and investigates the associated epistemic and political applications. Emphasis is placed on how Feyerabend supported certain aspects of relativism, and at what stage he rejected others. It is noted that Feyerabend had already imposed limitations on relativism in Farewell to Reason, in which he entertained the possibility of epistemic definition within stable contexts, and advanced the notion that opportunities and equality associated with political and cultural units could only be valid within a democratic system. In Conquest of Abundance, political relativism is largely discarded, while epistemological relativism is increasingly treated as an appeal for diversity in all areas.In this re-reading of his work, it becomes clear that Feyerabend was already advocating a moderate form of epistemic and political relativism in the middle of his career, which he subsequently developed in the direction of “ontological pluralism” in his later work. This paper thus shows that Feyerabend's relativism should not be completely rejected, but rather that it continues to offer interesting food for thought.

Vom Unwesen der Lüge

Lying in the sense of declaring as true what you believe to be false takes a special position within ethical discourse concerning truthfulness and the virtues and vices of communication. None of the many other ways in which people lack truthfulness is considered nearly as vicious as lying. However, in everyday life our attitude towards lying is far from consistent insofar as we tend to take both an absolutist and a relativist position towards lying. The article shows that our inconsistency derives from several philosophical traditions which have developed widely different concepts and moral attitudes with regard to lying. And with respect to the challenges of present life it is argued that instead of bending all our thoughts on lying, we should rather follow Michel Foucault and Bernard Williams in distinguishing the virtues of veracity we should cultivate in the different areas of modern life.

Approaches to relativistic positioning around Earth and error estimations

In the context of relativistic positioning, the coordinates of a given user may be calculated by using suitable information broadcast by a 4-tuple of satellites. Our 4-tuples belong to the Galileo constellation. Recently, we estimated the positioning errors due to uncertainties in the satellite world lines (U-errors). A distribution of U-errors was obtained, at various times, in a set of points covering a large region surrounding Earth. Here, the positioning errors associated to the simplifying assumption that photons move in Minkowski space–time (S-errors) are estimated and compared with the U-errors. Both errors have been calculated for the same points and times to make comparisons possible. For a certain realistic modeling of the world line uncertainties, the estimated S-errors have proved to be smaller than the U-errors, which shows that the approach based on the assumption that the Earth’s gravitational field produces negligible effects on photons may be used in a large region surrounding Earth. The applicability of this approach – which simplifies numerical calculations – to positioning problems, and the usefulness of our S-error maps, are pointed out. A better approach, based on the assumption that photons move in the Schwarzschild space–time governed by an idealized Earth, is also analyzed. More accurate descriptions of photon propagation involving non symmetric space–time structures are not necessary for ordinary positioning and spacecraft navigation around Earth.

Relativistic Positioning System in perturbed spacetime

We present a variant of a Global Navigation Satellite System called a Relativistic Positioning System (RPS), which is based on emission coordinates. We modelled the RPS dynamics in a spacetime around Earth, described by a perturbed Schwarzschild metric, where we included the perturbations due to Earth multipoles (up to the 6th), the Moon, the Sun, Venus, Jupiter, solid tide, ocean tide, and Kerr rotation effect. The exchange of signals between the satellites and a user was calculated using a ray-tracing method in the Schwarzschild spacetime. We find that positioning in a perturbed spacetime is feasible and is highly accurate already with standard numerical procedures: the positioning algorithms used to transform between the emission and the Schwarzschild coordinates of the user are very accurate and time efficient—on a laptop it takes 0.04 s to determine the user’s spatial and time coordinates with a relative accuracy of and respectively.

Let's get real: a critical semiotic analysis of Irish print media discourses

ABSTRACTIn what follows, I critically assess the merits of the relativist and realist positions in the social and human sciences, and argue that the relativisation of truth claims operates to mask relations of power and inequality, and also offers impunity to discursive mystifications denying the existence of both. Alternatively, I argue that the Critical Realist position, with its realist ontology and relativist epistemology, allows for the identification of such structures, and as a consequence of its emphasis on the materiality of discourse, for the identification of mystificatory meaning-making. And I operationalise my argument through critical analysis and commentary on four texts drawn from newspapers across the range for such in Ireland on the related issues of wealth and welfare.

Between Indifference and the Regimes of Truth. An Essay on Fundamentalism, Tolerance and Hypocrisy

There are two basic positions where tolerance as political strategy and moral viewpoint is rejected or made redundant. We are hostile to tolerance when we hold that we are defending an objective truth—religious or secular—which should also be defended and maintained by means of political and legal power. And tolerance become superfluous also when the affirmation of plurality becomes total, and tolerance identical to a vive la difference. As recent developments in my own country—the Netherlands—have demonstrated, the political outcome of this last position is remarkably enough not necessarily an all-inclusive relativistic tolerance. It may just as well be one of intolerance towards ‘believers’ of all kinds, in short: tolerance becomes polemical and belligerent. Turning to religious fundamentalism or ultra-orthodoxy could then become a possible (extreme) reaction to this relativistic and subjectivist position, as demonstrated in Isaac Bashevis Singer’s novel The Penitent. Between these two positions of hostility or indifference towards tolerance, we can situate that democratic attitude which may rightly be called ‘tolerance’. As ethical position, the tolerant citizen accepts the democratic disjunction between my (private) truth and the symmetrical justice between citizens. As political strategy, a tolerant democratic regime is based upon a political act of exclusion of what I will here call ‘political fundamentalism’.

Relativistic positioning in Schwarzschild space-time

In the Schwarzschild space-time created by an idealized static spherically symmetric Earth, two approaches -based on relativistic positioning- may be used to estimate the user position from the proper times broadcast by four satellites. In the first approach, satellites move in the Schwarzschild space-time and the photons emitted by the satellites follow null geodesics of the Minkowski space-time asymptotic to the Schwarzschild geometry. This assumption leads to positioning errors since the photon world lines are not geodesics of any Minkowski geometry. In the second approach -the most coherent one- satellites and photons move in the Schwarzschild space-time. This approach is a first order one in the dimensionless parameter GM/R (with the speed of light c=1). The two approaches give different inertial coordinates for a given user. The differences are estimated and appropriately represented for users located inside a great region surrounding Earth. The resulting values (errors) are small enough to justify the use of the first approach, which is the simplest and the most manageable one. The satellite evolution mimics that of the GALILEO global navigation satellite system.

An evolutionary logic towards the convergence of international business ethics

The fundamental problem in developing a theory of international business ethics, without imposing ethnocentric assumptions, lies in the inherent conflict between the need for universal ethics and the reality of diverse national cultures. Integrative social contracts theory holds an intermediate position between ethical universalist and relativist positions — recognizing universal hypernorms on the one hand and moral free space on the other. We argue that all businesses share a common objective of sustaining long-run economic value for their stakeholders. We develop this argument using an evolutionary logic into a hypernorm along three propositions: First, the firm influences, and is influenced by, members of the society (social context proposition). Second, managers maximize profit subject to joint constraints of technical feasibility and ethical norms (managerial decision proposition). Third, ethical norms evolve from interactions among the stakeholders without a central authority. Natural selection favors norms that maximize long run economic value for the society (natural selection proposition). We show that the hypernorm can spawn widely agreed authentic ethical norms. However, moral bounded rationality when interpreting the hypernorm generates different authentic norms in the moral free space. The evolutionary logic is testable along the dimensions of variation, inheritance and selection of ethical norms.

Fear of Relativism

Although scholars toss around the word “relativism” when debating the merits of various methodological approaches in international studies, there is a lack of clarity about what it might mean to have a relativist position on the production of social-scientific knowledge. As a result, a lot of the ink spilled about the potential dangers of relativism is overblown. A little philosophical and logical clarity goes a long way towards dispelling that particular bogeyman.

Dissociation among Psychoanalysts about Sexual Boundary Violations

The official condemnation of all sexual contact between psychotherapists and patients can be called the “absolutist position.” Some therapists harbor private views that differ from the absolutist position, such as the view that such relations may be more acceptable if they lead to a happy marriage, the “relativist position” or the “empathic-sentimental” position. A few clinicians have condoned such relationships, claiming that they are helpful to patients at least half the time, which is not supported by research. Mending the disconnection among public, private, and unconscious views may lead to more consistent and fair handling of sexual boundary violations.

Relativistic positioning: errors due to uncertainties in the satellite world lines

Global navigation satellite systems use appropriate satellite constellations to get the coordinates of an user—close to Earth—in an almost inertial reference system. We have simulated both GPS and GALILEO constellations. Uncertainties in the satellite world lines lead to dominant positioning errors. In this paper, a detailed analysis of these errors is developed inside a great region surrounding Earth. This analysis is performed in the framework of the so-called relativistic positioning systems. Our study is based on the Jacobian (J) of the transformation giving the emission coordinates in terms of the inertial ones. Around points of vanishing J, positioning errors are too large. We show that, for any 4-tuple of satellites, the points with J=0 are located at distances, D, from the Earth centre greater than about 2R/3, where R is the radius of the satellite orbits which are assumed to be circumferences. Our results strongly suggest that, for D-distances greater than 2R/3 and smaller than 105 km, a rather good positioning may be achieved by using appropriate satellite 4-tuples without J=0 points located in the user vicinity. The way to find these 4-tuples is discussed for arbitrary users with D<105 km and, then, preliminary considerations about satellite navigation at D<105 km are presented. Future work on the subject of space navigation—based on appropriate simulations—is in progress.

Note sulla teoria della politica monetaria

The theoretical foundations of monetary policy are made up from the analysis of the essential properties of money and the relations that link currencies to the economic system. From this double set of closely related principles derive the behavioural norms set for monetary authorities. The ongoing and unresolved debate on the actions of policymakers has its origins in the contrast between different approaches to the theory of money. This is due not so much to the dependence of the assumptions from the institutional framework, typical of a relativist position, as it is to the intrinsic complexity of the phenomena considered. The purpose of the present work is to discuss the limits and the significance of the different rules of conduct through a survey about the main characteristics of the underlying models.

Is “Non-Western Theory” Possible? The Idea of Multipolarity and the Trap of Epistemological Relativism in Russian IR

An important recent development in the discipline of International Relations (IR) has been the growing interest in the national schools and “non-core” theorizing. Even though this interest is fully justified, we argue that the tendency to describe all such schools as invariably promising and helpful in overcoming the Eurocentrism of the discipline is misguided. It originates in the false assumption that the infinite diversity of collective experiences throughout the world can only be approached on the basis of epistemological pluralism. We explore the confusion between the ontological and epistemological aspects of the problem by looking at the state of international studies in Russia. The development of Russian IR is defined by a controversy between pro-Western transitological approaches and the dominant relativist position centered around the doctrine of multipolarity. The latter is translated into the epistemological domain, leading to a totally counterproductive assertion that “Western” science is unable to understand Russia's specificity.

Factorization method for Schrödinger equation in relativistic configuration space and q-deformations

Review paper is devoted to the relativistic configuration space (RCS) concept, a version of the relativistic Quantum Mechanics in RCS, the generalization of the Dirac-Infeld-Hall factorization method in the framework of the noncommutative differential calculus natural for RCS, different versions of the deformed oscillators, emerging as the generalization of the harmonic oscillator for RCS. In the formulation of the Newton-Wigner postulates for the relativistic localized states the hypothesis of commutativity of the position operator components is silently accepted as an evident fact. In the present work it is shown that commutativity is not necessary condition and the alternative (noncommutative) approach to the relativistic position operator and localization concept can be realized in a framework of the physically as well as mathematically comprehensive scheme. The different generalizations of the Dirac-Infeld-Hall factorization method for this case are constructed. This method enables us to find out all possible generalizations of the most important nonrelativistic integrable case—the harmonic oscillator. It is shown also that the relativistic oscillator = q—oscillator.
