This contribution focuses on legal issues raised by the audiovisual broadcasting of performing arts, which has significantly increased due to the SARS-CoV-2 pandemic. First, we contextualize this practice and briefly present the emergence and evolution of the practice of “filmed theater”, as well as any other form of performances (e.g., concert, ballet, opera) originally conceived for the stage but subsequently diffused through other channels. Secondly, we address the current legal issues that have arisen because of the increase of such practice (...) due to the containment measures taken by government. Two axes are of particular attention: the matter of copyrights and related rights, on the one hand, and the question of public financing, on the other. Concerning intellectual property, audiovisual broadcasting leads to several legal consequences and issues: effectiveness of related rights, emergence of new modes of exploitation and new authors, recognition of the recording as an original work, etc. This new practice is, moreover, likely to disrupt the categories established by public funding legal mechanisms, which are often poorly adapted to hybrid artistic objects. The objective of this part is therefore to analyze the new legal issues raised by the audiovisual distribution of performances. Finally, we go beyond exclusively legal issues to examine the very specificities of performing arts and, more specifically, the possible loss that would result from a fixation of a production on a reproducible medium, making its diffusion possible beyond the stage.

The review analyzes the book The Conscience’s Double by Georgy Chernavin. I focus on the concepts of false twins of conscience, guilt, and duty in the extended context of philosophical and artistic discourse. The problem of the difference between conscience and its ersatz forms, which give rise to a distorted ethical consciousness, is considered. The main emphasis is opportunistic conscience, neurotic guilt, and false debt. The review suggests that Chernavin’s book studies the “sad theory” of moral disorientation and requires the (...) supplementation with a hypothetical “cringe theory.” In this case, the “sad theory” makes it possible to expand the phenomenological discourse by including a discussion of conscience, illustrating the uncertainty of the boundaries between the phenomenological and the symbolic, and highlighting the subject’s dependence on what they are not. In this work, there is a potential for developing an original ontology of the relationship between conscience and its evil counterpart, especially between a “spiritually sighted” and a “blindly corporeal” person. The scrutinized guilt for the lost absence of guilt is an experience that, although not lived, is important for the subject’s self-constitution. This experience, like the inner side of the subject, determines its conscious functioning and forms something like a Mobius strip. An Evil Genius makes this bond, and I am trying to conceptualize their “weakened” being. (shrink)

Changes in healthcare financing increasingly rely upon patient cost-sharing to control escalating healthcare expenditures. These changes raise new challenges for physicians that are different from those that arose either under managed care or traditional indemnity insurance. Historically, there have been two distinct bases for arguing that physicians should not consider costs in their clinical decisions—an “aspirational ethic” that exhorts physicians to treat all patients the same regardless of their ability to pay, and an “agency ethic” that calls on physicians to (...) be trustworthy advisors to their patients. In the setting of greater patient cost-sharing, physicians' aspiration and agency roles increasingly conflict. Satisfactorily navigating the new terrain of consumer-driven healthcare requires physicians to consider these two roles and how they can best be reconciled so as to maximize quality of care while respecting the heterogeneity of patients' financial resources and willingness to pay.

In this paper, missing attribute values in incomplete data sets have three possible interpretations: lost values, attribute-concept values and ‘do not care’ conditions. For rule induction, we use characteristic sets and generalized maximal consistent blocks. Therefore, we apply six different approaches for data mining. As follows from our previous experiments, where we used an error rate evaluated by ten-fold cross validation as the main criterion of quality, no approach is universally the best. Thus, we decided to compare our six approaches (...) using complexity of rule sets induced from incomplete data sets. We show that the smallest rule sets are induced from incomplete data sets with attribute-concept values, while the most complicated rule sets are induced from data sets with lost values. The choice between interpretations of missing attribute values is more important than the choice between characteristic sets and generalized maximal consistent blocks. (shrink)

In the debates surrounding the ethical dimensions of interventions in the human genome, much attention is paid to determining whether—and if so, how—market access to these technologies ought to be managed in order to maximize social benefit. There are those who advocate a “laissez-faire” free-market approach to the development and use of genetic and genomic interventions. We are sympathetic to this view insofar as we understand the workings of the market stimulus effect. We use the term “market stimulus effect” to (...) refer to the outcome of a set of mechanisms whereby early adoption of a new technology by wealthy consumers promotes the development of versions of this product that are cheaper to produce, or are simply ..

: The "difference position" holds that clinical research and therapeutic medical practice are sufficiently distinct activities to require different ethical rules and principles. The "similarity position" holds instead that clinical investigators ought to be bound by the same fundamental principles that govern therapeutic medicine—specifically, a duty to provide the optimal therapeutic benefit to each patient or subject. Some defenders of the similarity position defend it because of the overlap between the role of attending physician and the role of investigator in (...) a research trial. This overlap is maximal when the same physician occupies both roles with respect to a particular patient-subject. We address the ethical tensions inherent in that role conflict and argue that the tensions are real but manageable. The difference position provides a sound ethical framework within which to manage those tensions, while the similarity position is unsatisfactory because it seeks to deny the existence of the tensions.

The presence of stigmatizing language in the electronic health record (EHR) has been used to measure implicit biases that underlie health inequities. The purpose of this study was to identify the presence of stigmatizing language in the clinical notes of pregnant people during the birth admission. We conducted a qualitative analysis on N = 1117 birth admission EHR notes from two urban hospitals in 2017. We identified stigmatizing language categories, such as Disapproval (39.3%), Questioning patient credibility (37.7%), Difficult patient (21.3%), (...) Stereotyping (1.6%), and Unilateral decisions (1.6%) in 61 notes (5.4%). We also defined a new stigmatizing language category indicating Power/privilege. This was present in 37 notes (3.3%) and signaled approval of social status, upholding a hierarchy of bias. The stigmatizing language was most frequently identified in birth admission triage notes (16%) and least frequently in social work initial assessments (13.7%). We found that clinicians from various disciplines recorded stigmatizing language in the medical records of birthing people. This language was used to question birthing people's credibility and convey disapproval of decision‐making abilities for themselves or their newborns. We reported a Power/privilege language bias in the inconsistent documentation of traits considered favorable for patient outcomes (e.g., employment status). Future work on stigmatizing language may inform tailored interventions to improve perinatal outcomes for all birthing people and their families. (shrink)

This paper gives prescriptions for introducing ethical concerns into the economic theory of the firm. Topics include social responsibility, corporate governance, profit maximization, competition barriers, collusion, the market system, and welfare economics. The need for such prescriptions is based on a content analysis of 21 managerial economics texts for their coverage of ethics. My analysis finds that substantive discussions of ethics are conspicuous by their absence. As ethical breaches can involve significant monetary damages to a firm - particularly through adverse (...) market reactions - moral-reasoning abilities can complement analytical skills. Consequently, my analysis demonstrates how ethics figure into the opportunity costs of managerial decision making, which is central to the economic definition of profit. (shrink)

The fundamental tenet of modern empiricism is the view that all non-analytic knowledge is based on experience. Let us call this thesis the principle of empiricism. [1] Contemporary logical empiricism has added [2] to it the maxim that a sentence makes a cognitively meaningful assertion, and thus can be said to be either true or false, only if it is either (1) analytic or self-contradictory or (2) capable, at least in principle, of experiential test. According to this so-called empiricist (...) criterion of cognitive meaning, or of cognitive significance, many of the formulations of traditional metaphysics and large parts of epistemology are devoid of cognitive significance--however rich some of them may be in non-cognitive import by virtue of their emotive appeal or the moral inspiration they offer. Similarly certain doctrines which have been, at one time or another, formulated within empirical science or its border disciplines are so contrived as to be incapable of test by any conceivable evidence; they are therefore qualified as pseudo- [p. 42:] hypotheses, which assert nothing, and which therefore have no explanatory or predictive force whatever. This verdict applies, for example, to the neo-vitalist speculations about entelechies or vital forces, and to the "telefinalist hypothesis" propounded by Lecomte du Noüy. (shrink)

In quantum field theory, coherent states can be created that have negative energy density, meaning it is below that of empty space, the free quantum vacuum. If no restrictions existed regarding the concentration and permanence of negative energy regions, it might, for example, be possible to produce exotic phenomena such as Lorentzian traversable wormholes, warp drives, time machines, violations of the second law of thermodynamics, and naked singularities. Quantum Inequalities have been proposed that restrict the size and duration of the (...) regions of negative quantum vacuum energy that can be accessed by observers. However, QIs generally are derived for situations in cosmology and are very difficult to test. Direct measurement of vacuum energy is difficult and to date no QI has been tested experimentally. We test a proposed QI for squeezed light by a meta-analysis of published data obtained from experiments with optical parametric amplifiers and balanced homodyne detection. Over the last three decades, researchers in quantum optics have been trying to maximize the squeezing of the quantum vacuum and have succeeded in reducing the variance in the quantum vacuum fluctuations to \ dB. To apply the QI, a time sampling function is required. In our meta-analysis different time sampling functions for the QI were examined, but in all physically reasonable cases the QI is violated by much or all of the measured data. This brings into question the basis for QI. Possible explanations are given for this surprising result. (shrink)

Representation theorems are often taken to provide the foundations for decision theory. First, they are taken to characterize degrees of belief and utilities. Second, they are taken to justify two fundamental rules of rationality: that we should have probabilistic degrees of belief and that we should act as expected utility maximizers. We argue that representation theorems cannot serve either of these foundational purposes, and that recent attempts to defend the foundational importance of representation theorems are unsuccessful. As a result, we (...) should reject these claims, and lay the foundations of decision theory on firmer ground. (shrink)

_Winner of the Fabian Dorsch ESA Essay Prize._ Julian Dodd defends the view that, in musical work-performance practice, interpretive authenticity is a more fundamental value than score compliance authenticity. According to him, compliance with a work’s score can be sacrificed in cases where it conflicts with interpretative authenticity. Stephen Davies and Andrew Kania reject this view, arguing that, if a performer intentionally departs from a work’s score, she is not properly instantiating that work and hence not producing an authentic performance (...) of it. I argue that this objection fails. A detailed analysis of work-performance practice reveals, first, that the normative scope of interpretive authenticity encompasses the practice of composing musical versions and that, second, when performers sacrifice score compliance to maximize interpretive authenticity, they are performing the target work by means of performing a version of it. By means of the nested types theory, I then show how performances produced in this way can be properly formed instances, and hence authentic performances, of their target work. (shrink)

In this paper incomplete data sets, or data sets with missing attribute values, have three interpretations, lost values, attribute-concept values and ‘do not care’ conditions. Additionally, the process of data mining is based on two types of probabilistic approximations, global and saturated. We present results of experiments on mining incomplete data sets using six approaches, combining three interpretations of missing attribute values with two types of probabilistic approximations. We compare our six approaches, using the error rate computed as a result (...) of ten-fold cross validation as a criterion of quality. We show that for some data sets the error rate is significantly smaller (5% level of significance) for lost values, for some data sets the smaller error rate is associated with attribute-concept values, and sometimes with ‘do not care’ conditions. Again, for some approaches the error rate is significantly smaller for saturated probabilistic approximations than for global probabilistic approximations, while for some approaches it is the other way around. Thus, for an incomplete data set, the best approach to data mining should be chosen by trying all six approaches. (shrink)

A criticism of Frankfurt-counterexamples presented by David Widerker and known as the W-defense has been resilient for years and has been considered one of the strongest challenges these counterexamples have to face. In this paper I intend to offer an explanation of one of the appeals on the W-Defense, mainly, that it allows us to pass over the intricate debate on whether a successful Frankfurt counterexample can be presented or not. I defend this debate, although interesting and fruitful, misses the (...) main point Frankfurt counterexamples intend to make. Next I offer a defense of Frankfurt counterexamples from Widerker’s attack by presenting a dilemma for the Principle of Alternative Expectations, it’s main premise: either on the one hand, this principle rests on the Kantian maxim ought implies can, which makes the principle, and Widerker’s whole argument, redundant and unnecessary; or the principle does not rest on such maxim, but then there is no good reason to accept it a valid.

En este texto defiendo los contraejemplos tipo-Frankfurt de este ataque de Widerker presentando un dilema en el que su premisa fundamental, el Principio de expectativas alternativas, se ve envuelta: o bien la plausibilidad de este principio depende de la máxima kantiana "deber" implica "poder", lo cual haría (...) que el principio mismo, y con él todo el argumento de Widerker, sea redundante y prescindible; o bien no se basa en esta máxima, pero entonces no hay ninguna razón de fuerza por la cual se pudiera defender que este principio debe ser aceptado como válido.

This study examines the deliberations of professional MBA students when presented with a dilemma that weighs the difference between commitments to profit-maximization against concerns for fired workers who would need to seek a new job during a recession. Using content analysis, accounting, economic, and ethically based rationales that differ from the profit-maximizing recommendation are categorized. Results also show that those who make non-profit-maximizing recommendations consider, but ultimately reject the profit-maximizing approach to layoffs.

A market may be defined as a set of competitive relationships in which agents strive, within limits set by ground rules, to better their own economic positions, not necessarily at the expense of other people, but not necessarily not at their expense either. A degree of indifference to the market fates of others is, manifestly, an inevitable feature of the market practice, so defined. But though indifference is clearly logically endemic to markets, it has been denied that selfishness is necessarily (...) involved in the raw competition of market activity. Thus, Hayek maintains that market behaviour is not selfish on the grounds that the market is a competitive non zero-sum ‘wealth-creating game’ in which individuals ‘use their own knowledge for their own ends’ in a system whose operations,viathe ‘Invisible Hand’, also produce unintended benefits for others. But for behaviour to be selfish it clearly need not necessarily disbenefit other people; it is enough that it is pursued, or persisted in, regardless of its effects upon others. And this is precisely what the institutional ‘indifference’ of market activity amounts to. Admittedly individuals who understand the Hayekian logic of the market know that the long-run chances of everyone's benefiting are maximized by acting in a rigorously competitive manner, and so they at least in one sense act with a ‘regard for others’. Butipso factothis category of market agents has an even stronger reason than the ignorantly selfish for disregarding thespecificinterests of all theparticularindividuals with whom they have economically to do. ‘Market selfishness’, the disregard for others' market interests, is thus a logically inevitable feature of market activity.

BackgroundThe expectation of pandemic-induced severe resource shortages has prompted authorities to draft and update frameworks to guide clinical decision-making and patient triage. While these documents differ in scope, they share a utilitarian focus on the maximization of benefit. This utilitarian view necessarily marginalizes certain groups, in particular individuals with increased medical needs.Main bodyHere, we posit that engagement with the disability critique demands that we broaden our understandings of justice and fairness in clinical decision-making and patient triage. We propose the capabilities (...) theory, which recognizes that justice requires a range of positive capabilities/freedoms conducive to the achievement of meaningful life goals, as a means to do so. Informed by a disability rights critique of the clinical response to the pandemic, we offer direction for the construction of future clinical triage protocols which will avoid ableist biases by incorporating a broader apprehension of what it means to be human.ConclusionThe clinical pandemic response, codified across triage protocols, should embrace a form of justice which incorporates a vision of pluralistic human capabilities and a valuing of positive freedoms.

In that case it leads to a purely classical relation between G and the classical string coupling constant α′ and the velocity of light c which (...) does not involve Planck's constant. (shrink)

Revisionist interpretation of Mill needs to be extended to deal with a residue of puzzles about his moral theory and its connection with his theory of liberty. The upshot shows his reinterpretation of his Benthamite tradition as a form of ‘philosophical utilitarianism’; his definition of the art of morality as collective self-defence; his ignoring of maximization in favour of ad hoc dealing in utilities; the central role of his account of the justice of punishment; the marginal role of the internal (...) sanction in his criterion of moral wrong; his deep respect for common-sense morality; and his restriction of the scope of morality so as to claim for the utilitarian tradition the whole realm of the aesthetics of conduct as part of a general theory of practical reason.

Jim Joyce has presented an argument for Probabilism based on considerations of epistemic utility [Joyce, 1998]. In a recent paper, I adapted this argument to give an argument for Probablism and the Principal Principle based on similar considerations [Pettigrew, 2012]. Joyce’s argument assumes that a credence in a true proposition is better the closer it is to maximal credence, whilst a credence in a false proposition is better the closer it is to minimal credence. By contrast, my argument in that (...) paper assumed (roughly) that a credence in a proposition is better the closer it is to the objective chance of that proposition. In this paper, I present an epistemic utility argument for Probabilism and the Principal Principle that retains Joyce’s assumption rather than the alternative I endorsed in the earlier paper. I argue that this results in a superior argument for these norms. (shrink)

Lainie Friedman Ross suggests that clinicians increase our efforts to meet children’s most basic needs in several ways.

Virtue ethics, the authors believe, is distinct and superior to other options because it considers, in the first place, which preferences are worth pursuing, rather than just blindly maximizing preferences, and it takes into account intuitions, emotions and experience, instead of acting solely on abstract universal principles.

The 3Rs, or the replacement, reduction, and refinement of animal research, are widely accepted as the best approach to maximizing high-quality science while ensuring the highest standard of ethical consideration is applied in regulating the use of animals in scientific procedures. This contrasts with the muted scientific interest in the 3Rs when they were first proposed in The Principles of Humane Experimental Technique. Indeed, the relative success of the 3Rs has done little to encourage engagement with their original text, which (...) remains little read and out of print. By adopting a historical perspective, this article argues that one explanation for this disjunction may be found in another, more celebrated, event of 1959: C. P. Snow’s Rede lecture on The Two Cultures. The moral outlook of The Principles of Humane Experimental Technique derived from an earlier ethos wherein humanistic and scientific values occupied a shared culture. While the synthetic style of The Principles has hindered its readership, this article concludes that there is value to recovering the notion that the humanities and social sciences can contribute to the improvement of animal research.

The purpose of this paper is to show how a MacIntyre-inspired business school could contribute to developing practical wisdom in students through its curriculum, methods, faculty, student selection criteria, and governance. Despite MacIntyre's critiques, management can be presented, in MacIntyrean terms, as a second-order, domain-relative practice, with practical wisdom as corresponding virtue. Management education consists in developing practical wisdom. How? Primarily by initiating students and enabling them to participate in communal traditions of inquiry focused on, although not limited to, the (...) purposes and ends of business. The transmission of objective knowledge, analytical skills, and techniques is subordinated to the end goal. We consider traditions centered on shareholder value maximization, the balancing of stakeholder interests, and the fulfillment of the common good of firms. Each gives rise to a particular kind of business school. A MacIntyrean business school is one that seeks the common good of firms. (shrink)

The universality test is a significant reflective procedure, owing to which Kant’s categorical imperative is brought into proximity with moral practice and with an agent’s decisions made in particular circumstances and at the face of value collisions. The test is to be done in every single case by a moral agent her/himself and it aims to examine a selected maxim for its universality, that is to its congruity to universal and necessary moral law and hence to its moral dignity. (...) This issue has been broadly developed during the last century either within Kant studies, or in positive philosophical discussions, often sharply polemical. The paper represents some positions in those discussions. No matter how important the universality test in an agent’s moral decisions, so far universality signifies one of three embodiments of the categorical imperative, it would be wrong to consider the test the only criterion of moral dignity. This is true both within the Kantian conception of morality and more so beyond it. The paper proposes the Golden Rule as a critical correlation to the categorical imperative with its universality test. The rule also presupposes a kind of universalizability procedure. However, if the universality test set up by the categorical imperative is based on congruence of a maxim with the universal law, universalizability grounded on the Golden Rule consists in delocalization of intentions by taking into consideration the Other in her/his general and particular dispositions.

A "problem" book which reads, throughout too many of its pages, like an almanac of distinctions. Yet Bunge's discussions of partial truth, causality and chance, and especially of metanomological statements restore the balance and lend support to his thesis: science as a body of knowledge must be regarded as a set of systems of propositions and proposals of many kinds with the aim of "the maximization of the degree of truth."--G.

Four well-known claims about the nature of scientific knowledge can be conjoined to challenge the traditional value-neutrality thesis. These are the Duhem-Quine thesis, the Kuhnian thesis, the "publicity of science" claim, and the "reflexivity of social inquiry" claim. Maximal objectivity reqnires not value-neutrality, but a commitment by the researcher to certain social values—namely those which tend to equalize political advantage in a community. This is an epistemological, not an ethical, argument.

Ethics, in the sense of a recognized branch of inquiry, reputedly began with Socrates and the Sophists, at least for the western world. Ethics, understood as a set of moral standards, traditionalized by maxims and admonitions, has existed in human cultures from so early a time that it would be hazardous indeed to conjecture the date of its probable origin. The "Hopi Ethics" which Mr. Brandt has studied is obviously that of this second sense, whereas his own study, at least (...) insofar as it is a "theoretical analysis" and goes beyond mere description, is "ethics" in the first sense. That the Hopi Indians were somewhat astonished and perplexed by Mr. Brandt's line of inquiry is indicated by some of their quoted remarks, such as their mention of the "hard questions" being put to them, and their amazement at the suggestion of the possibility that "there is no right answer to ethical questions." One gathers, thus, that while the problem of ethical relativism was of high concern to Mr. Brandt, such an idea was nigh unthinkable to the Hopi. (shrink)

Two years ago, astrophysicists studying Type Ia supernovas discovered that our universe is a much stranger place than we had imagined, with invisible vacuum energy accelerating its expansion. (See my column about this in the May-1999 Analog.)

This book develops dynamic economic models using the perspective and analytic framework provided by psychological learning theory. This framework is used to resolve apparent contradictions between optimization theory, which lies at the heart of all modern economic theory, and day-to-day evidence that short-run economic behaviour cannot reasonably be described solely as the outcome of efficiently implemented self-interest. The author applies this viewpoint to a number of problem areas in which literal applications of maximization theory have not usually proved to be (...) satisfactory. These include analyses of decision-making under uncertainty and gambling behaviour, the role of consumer-oriented advertising in influencing behaviour, the persistence of price dispersions in markets, and inflation.

Theories that use expected utility maximization to evaluate acts have difficulty handling cases with infinitely many utility contributions. In this paper I present and motivate a way of modifying such theories to deal with these cases, employing what I call “Direct Difference Taking”.

I then compare my account to the most plausible alternative, (...) a proposal offered by Arntzenius :31–58, 2014). I argue that while Arntzenius’s proposal has many attractive features, it runs into a number of problems which Direct Difference Taking avoids. (shrink)

The aim of this paper is to verify whether step aerobics training has an impact on the temperature of deep muscles of the spine of young, healthy subjects and if there exists a relationship between the maximal oxygen uptake and thermal results. The study was conducted in a group of 21 subjects of both sexes, aged 20.2 ± 0.38. The step aerobics training sessions lasted 30 weeks, one training session per week, 60 minutes per session. Thermograms of the spine were (...) taken with the use of an infrared thermographic camera. Instrumental measurements included BMI, vital capacity of the lungs, and maximal oxygen uptake. After a 30-weeklong SAT, a statistically significant increase in the average temperature of the muscles of the thoracic and lumbar spine was observed in subjects of both sexes. The relationship between VO2max and temperature of the muscles of the thoracic and lumbar spine after the 30th SAT was not statistically significant. The study showed that a 30-weeklong step aerobics training had a positive impact on thermoregulation of apparently healthy male and female subjects aged 20. Furthermore, it can be safely assumed that thermography may be used as a non-invasive method of examination of the thermoregulation mechanism of SAT participants. (shrink)
