The Wigner distribution has proven to be a useful tool in many quantum problems requiring a joint distribution of position and momentum. In the present paper we develop a joint distribution for spin components within the spirit of the Wigner distribution. This distribution provides an insight into the quantum theory of measurement. We also discuss how one may write joint distributions for two arbitrary noncommuting operators.

We present, in various limits, analytical expressions for the center-of-mass wave function of a spin-1/2 atom as it is deflected by a Stern-Gerlach apparatus.

In the present paper we expand upon ideas published some time ago in connection with which path detectors based on the micromaser. Frequently questions arise concerning the time ordering of detection and eraser events. We here show, by a detailed and careful analysis of a quantum eraser experimental setup, that the experimenter can choose to ascertain particle-like which path information or wavelike interference information even after the atom has hit the screen.

We review the concepts and the physics behind electromagnetically induced transparency (EIT) and lasing without inversion (LWI) for various models of the V-type configurations.

This year marks the 50th anniversary of the birth of the celebrated Wigner distribution function. Many advances made in various areas of science during the 50 year period can be attributed to the physical insights that the Wigner distribution function provides when applied to specific problems. In this paper the usefulness of the Wigner distribution function in collision theory is described.

A Λ-type inversionless laser scheme is analyzed in which lasing is achieved under conditions when a conventional or a Raman laser would fail to operate. The dependence of gain on the parameters of the system is studied numerically. A realization in heliumlike ions is proposed which permits laser action at a wavelength of around 6 nm.

When Humpty-Dumpty had his great fall nobody could put him together again. A vastly more moderate challenge is to reunite the two partial beams of a Stern-Gerlach apparatus with such precision that the original spin state is recovered. Nevertheless, as we demonstrate, a substantial loss of spin coherence always occurs, unless the experimenter is able to control the magnetic field's inhomogeneity with an accuracy of at least one part in 105.

We have conducted an experimental study of V-type electromagnetically induced transparency in sodium. Its principles are elucidated by a simple model. Measurements show decreased fluorescence and absorption depending on the detuning of the driving and probe fields, which is in agreement with the results of numerical simulation.

Two-classes of phase-space spin quasi-distribution functions are introduced and discussed. The first class of these distributions is based on the delta function construction. It is shown that such a construction can be carried out for an arbitrary spin s and an arbitrary ordering of the spin operators. The second class of the spin distributions is constructed with the help of the spin coherent states. The connection of the spin coherent states to the Stratonovich formalism is established and discussed. It is (...) shown that the c-number phase-space description of quantum fluctuations provides a simple statistical picture of quantum fluctuations of spinoperators in terms of random directions on a unit sphere. For quantum states of the spin system the statistics of these random orientations is given by non-positive spin quasi-distribution functions. It is shown that the application of these spin quasi-distribution functions to the Einstein-Podolsky-Rosen correlations provide an insight into the quantum theory of measurement. (shrink)

It is found that a coherent state of the cavity field can be generated in a micromaser with injected atoms in a coherent superposition of the upper and lower states. The dependence of the density matrix elements of the field on the number of injected atoms indicates that due to the same initial atomic coherence the emission of separately injected single atoms in the cavity is a cooperative process.

Race, Crime, and the Law. Randall Kennedy. New York: Vintage Books/Random House, 1997, xiv + 539 pp.

abstract In this paper we question the basis on which judgements are made about the ‘quality’ of the lives of people whose embodied experience is anomalous, specifically in cases of impairments. In moral and political philosophy it is often assumed that, suitably informed, we can overcome epistemic gaps through the exercise of moral imagination: ‘putting ourselves in the place of others’, we can share their points of view. Drawing on phenomenology and theories of embodied cognition, and on empirical studies, we (...) suggest that there are barriers to imagining oneself differently situated, or imagining being another person, arising in part from the way imagination is constrained by embodied experience. We argue that the role of imagination in moral engagement with others is to expand the scope of our sympathies rather than to enable us to put ourselves in the other's place. We argue for explicit acknowledgement that our assessments of others’ QOL are likely to be shaped by the specifics of our own embodiment, and by the assumptions we make as a consequence about what is necessary for a good quality of life.

This book reconceives disability as a set of social relations and practices, as experienced embodiment, and as an emancipatory movement, as well as a biomedical phenomenon. The author brings new attention to complex ethical questions surrounding disability, looking at not only the biomedical understanding of impairment, but also its cultural representations and social organization.

Y a-t-il un art communiste? was given as a talk at the Grand Palais in Paris on 10 April 2019 on the occasion of a special exhibition, Red: Art and Utopia in the Land of the Soviets (Rouge: Art et utopie au pays des Soviets). The exhibition ran from 20 March 2019 to 1 July 2019. Red displayed works produced in the wake of the October Revolution of 1917 to the death of Joseph Stalin in 1953. This covers early experiments (...) by avant-garde artists such as Vladimir Mayokovsky and Kazimir Malevich, the grand-scale construction of public monuments, and the mass-produced art of Vladimir Tatlin and Alexander Rodchenko. Like many of Jacques Rancière’s recent publications on art, this article closely engages the material of its source exhibit, and, in it, he addresses the full range of art staged by the Grand Palais, offering a direct and provocative confrontation with the question of whether there can be a communist art.

The sharing economy has been examined from many angles, including the engagement of customers, the capabilities of the technological platforms, and the experiences of those who sell products or services. We focus on labor in the sharing economy. Labor has been regarded as one type of asset exchanged in the sharing economy, as part of the customer interface when services are sold, or as a party vulnerable to exploitation. We focus on labor as a position in relationship to owners of (...) capital. While new typologies to characterize the sharing economy are emerging, we argue that a well-established framework that has been applied across historic types of work arrangements can offer a robust analysis of enduring and new labor issues. We draw upon labor process theory from early formulations to recent applications to guide an analysis appropriate to the sharing economy. We use both central and less explored concepts from LPT and use Uber as a case to illustrate application of the framework. By considering labor, capital, and the power dynamics between them, we draw attention to unequal exchange and distributive justice, fundamental for taking a business ethics approach to labor in the sharing economy.

"And God said, Let us make man in our image, after our likeness and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth." --Genesis 1:24-26 In this crucial passage from the Old Testament, God grants mankind power over animals. But with this privilege comes the grave responsibility to respect life, to treat animals with (...) simple dignity and compassion. Somewhere along the way, something has gone wrong. In Dominion , we witness the annual convention of Safari Club International, an organization whose wealthier members will pay up to $20,000 to hunt an elephant, a lion or another animal, either abroad or in American "safari ranches," where the animals are fenced in pens. We attend the annual International Whaling Commission conference, where the skewed politics of the whaling industry come to light, and the focus is on developing more lethal, but not more merciful, methods of harvesting "living marine resources." And we visit a gargantuan American "factory farm," where animals are treated as mere product and raised in conditions of mass confinement, bred for passivity and bulk, inseminated and fed with machines, kept in tightly confined stalls for the entirety of their lives, and slaughtered in a way that maximizes profits and minimizes decency. Throughout Dominion , Scully counters the hypocritical arguments that attempt to excuse animal abuse: from those who argue that the Bible's message permits mankind to use animals as it pleases, to the hunter's argument that through hunting animal populations are controlled, to the popular and "scientifically proven" notions that animals cannot feel pain, experience no emotions, and are not conscious of their own lives. The result is eye opening, painful and infuriating, insightful and rewarding. Dominion is a plea for human benevolence and mercy, a scathing attack on those who would dismiss animal activists as mere sentimentalists, and a demand for reform from the government down to the individual. Matthew Scully has created a groundbreaking work, a book of lasting power and importance for all of us. (shrink)

The work of a bioethicist carries distinctive responsibilities. Alongside those of any worker, there are responsibilities associated with giving guidance to practitioners, policy makers and the public. In addition, bioethicists are professionally exposed to and required to identify situations of moral trouble, and as a result may find themselves choosing to work as advocates or activists, with responsibilities that are distinct from those generally acknowledged within academia. The requirement for bioethics to make normative judgements entails taking a stance, which means (...) there cannot be a sharp line between ‘academic’ or ‘objective’ bioethics, and advocacy/activism, but a continuum of bioethicists’ engagement and an associated continuum of responsibilities.

Time pressure has been shown to have a negative impact on ethical decision-making. This paper uses an experimental approach to examine the impact of an antecedent of time pressure, whether it is anticipated or not, on participants’ perceptions of unethical behaviour. Utilising 60 business school students at an Australian university, we examine the differential impact of anticipated and unanticipated time deadline pressure on participants’ perceptions of the likelihood of unethical behaviour occurring. We find the perception of the likelihood of unethical (...) behaviour occurring to be significantly reduced when time pressure is anticipated rather than unanticipated. The implications of this finding for both professional service organisations and tertiary institutions are considered. (shrink)

Susan has been profoundly deaf since childhood. She is a hearing aid wearer, and likes to use the induction loops built into some public spaces, such as theaters and cinemas, to help cut down the background noise that can make hearing speech very difficult. But this depends on the building having an induction loop fitted and properly maintained. Like many other induction loop users, Susan frequently finds that the advertised loop system is either working poorly or not working at all. (...) Almost as often, she then has the experience of making a complaint about it only to have the problem denied. If she persists, she is often then met... (shrink)

Pandemics such as COVID-19 place everyone at risk, but certain kinds of risk are differentially severe for groups already made vulnerable by pre-existing forms of social injustice and discrimination. For people with disability, persisting and ubiquitous disablism is played out in a variety of ways in clinical and public health contexts. This paper examines the impact of disablism on pandemic triage guidance for allocation of critical care. It identifies three underlying disablist assumptions about disability and health status, quality of life, (...) and social utility, that unjustly and potentially catastrophically disadvantage people with disability in COVID-19 and other global health emergencies.

Schools are interesting as complex organizations in and of themselves but even more so for how they refract the societal dynamics by which inequality is reproduced, an enduringly vexing question (Fligstein & McAdam, 2012:3). Educational attainment is core to socioeconomic status and connected to outcomes in housing, health, and employment. Unequal schools in fields characterized by stratification are often the subject of reform attempts (Tyack, 1974). We examine how a wealthier and a poorer school responded to a state-level regulatory mandate (...) for change, in the U.S. context of schools as putative engines of opportunity. Bourdieu’s “master concepts” of field, habitus, and cultural capital (Swartz, 2008) are often applied, and we used them to answer frequent but still relatively unanswered calls in the literature: first, to use the master concepts together rather than singularly, and second, to attend specifically to the organization level and what it refracts (Dobbin, 2008; Emirbayer & Johnson, 2008; Hallett & Gougherty, 2018; Lounsbury & Ventresca, 2003; Mohr, 2013). For this integrative and organizational level approach, we derived the concept of “class signature,” which enabled us to focus on practices in organizations. This lens revealed “resistant compliance” in the wealthier school and “compliant resistance” in the poorer school, both of which reshaped the stratified field, even if stratification was not rectified. These responses appeared to reproduce inequality, not simplistically, we argue, but along a winding path fraught with practical experiments, protection against penalties, redefinition of the reform’s terms, and some small gains to remedy intra-organizational inequalities.

The question of whether activism should be overtly embraced as part of the bioethicist's role deserves serious consideration. Like others, we agree that bioethics is inescapably partisan; bioethical deliberation is based on trying to determine morally relevant features of situations and morally justifiable outcomes. Where disagreement arises is over the degree to which bioethicists should be activists. Meyers argues for a somewhat circumscribed role, limited to action on ethically concerning institutional matters, for those who are financially independent of the institutions. (...) We take a broader view, arguing that some issues are so morally egregious that there is a duty to take a stand against them, even if the prospects of success are dim. There is a need for further debate, sharing of experiences, and analysis of case studies, to support bioethicists who take a stand. (shrink)

While most business ethics texts focus exclusively on individual decision making--what should an individual do--this resource presents the whole business ethics story. Highly realistic, readable, and down-to-earth, it moves from the individual to the managerial to the organizational level, focusing on business ethics in an organizational context to promote an understanding of complex influences on behavior. The new Fifth Edition is the perfect text for students entering the workplace, those seeking to become professionals in training, communications, compliance, in addition to (...) chief ethics officers, corporate counsel, heads of human resources, and senior executives.

Mitochondrial replacement techniques are intended to avoid the transmission of mitochondrial diseases from mother to child. MRT represent a potentially powerful new biomedical technology with ethical, policy, economic and social implications. Among other ethical questions raised are concerns about the possible effects on the identity of children born from MRT, their families, and the providers or donors of mitochondria. It has been suggested that MRT can influence identity directly, through altering the genetic makeup and physical characteristics of the child, or (...) indirectly through changing the child's experience of disease, and by generating novel intrafamilial relationships that shape the sense of self. In this article I consider the plausibility and ethical implications of these proposed identity effects, but I focus instead on a third way in which identity may be affected, through the mediating influence of the wider social world on MRT effects on identity. By taking a narrative approach, and examining the nature and availability of identity narratives, I conclude that while neither direct genetic nor indirect experiential effects can be excluded, social responses to MRT are more likely to have a significant and potentially damaging influence on the generation of MRT children's narratives of identity. This conclusion carries some implications for the collective moral responsibility we hold to ensure that MRT, if implemented, are practised in ethically justifiable ways. (shrink)

ABSTRACT The part played by time in ethics is often taken for granted, yet time is essential to moral decision making. This paper looks at time in ethical decisions about having a genetic test. We use a patient‐centred approach, combining empirical research methods with normative ethical analysis to investigate the patients' experience of time in (i) prenatal testing of a foetus for a genetic condition, (ii) predictive or diagnostic testing for breast and colon cancer, or (iii) testing for Huntington's disease (...) (HD). We found that participants often manipulated their experience of time, either using a stepwise process of microdecisions to extend it or, under the time pressure of pregnancy, changing their temporal ‘depth of field’. We discuss the implications of these strategies for normative concepts of moral agency, and for clinical ethics. (shrink)

This paper is based on linked qualitative studies of the donation of human embryos to stem cell research carried out in the United Kingdom, Switzerland, and China. All three studies used semi-structured interview protocols to allow an in-depth examination of donors’ and non-donors’ rationales for their donation decisions, with the aim of gaining information on contextual and other factors that play a role in donor decisions and identifying how these relate to factors that are more usually included in evaluations made (...) by theoretical ethics. Our findings have implications for one factor that has previously been suggested as being of ethical concern: the role of gratitude. Our empirical work shows no evidence that interpersonal gratitude is an important factor, but it does support the existence of a solidarity-based desire to “give something back” to medical research. Thus, we use empirical data to expand and refine the conceptual basis of bioethically theorizing the IVF–stem cell interface. (shrink)

This article reviews recent developments within a number of academic disciplines pointing toward an increasing importance of imagination for understanding morality and cognition. Using elements from hermeneutics and metaphor theory, it works toward a framework for a more context-sensitive understanding of human agency, especially focusing on moral deliberation and change. The analytic framework is used to analyze the story of a patient making tough decisions in the context of prenatal diagnosis. We show how a relatively stable outlook on the world, (...) here called the “baseline of choice,” is challenged by unexpected events and how imaginative processes enter into the active creation of a new moral order. The ensuing interpretation is then placed within a broader philosophical landscape. John Dewey’s notion of “dramatic rehearsal” is put forward as one particularly promising way of understanding moral imagination, deliberation, and decision-making. (shrink)

This chapter examines the ways in which disabled people are subject to epistemic injustice. It starts by introducing how social epistemology models the creation of shared knowledge and then uses feminist epistemology to highlight the role of social and political power in producing epistemic privilege, exclusion, and oppression. The well-known concepts of testimonial and hermeneutic epistemic injustice are discussed in relation to disability, showing how these forms of injustice are frequently experienced within the lives of disabled people. In particular, disabled (...) experience has features that distinguish it from the experiences of sexism and racism most commonly used as illustrations of epistemic injustice. The chapter ends by arguing that the potential for epistemic injustice poses unprecedented risks for disabled people in the current context, which could be minimized by recognizing that ignorance about disabled lives is not inevitable, but something that can and should be challenged.

In this paper I consider one effect that disablism has on social interactions between nondisabled and disabled people: the “hidden labor” carried out by disabled people to manage or manipulate the presentation of their impairment to others, and their own and others’ emotional responses, in order to achieve their goals. Although such management may be understood as actively enhancing the disabled person’s autonomous agency, I argue that the cost of this labor to the disabled person and the fact that it (...) must be hidden from the nondisabled partner in order to be effective, create an ethical problem. Such interactions confer a form of autonomy through a connection that is fundamentally distorted by asymmetries of power, knowledge, risk, and is therefore ethically undesirable. (shrink)
