Beginning with Einstein's special and general theories of relativity, the authors give a detailed mathematical description of fundamental astrophysical radiation processes, including Compton scattering of electrons and photons, synchrotron radiation of particles in magnetic fields, and much more.

Although consumers increasingly claim to demand ethical products and state that they are willing to reward firms that are ethical, studies have highlighted that there is a significant gap between consumers’ explicit attitudes toward ethical products and their actual purchase behavior. This has major implications for firm policies revolving around business ethics. This research contributes to the understanding of the attitude–behavior gap in ethical consumption that literature has identified but not explored much. We utilize the model of dual attitudes as (...) a basis for the arguments presented in the paper and test them. We suggest that the gap in ethical consumerism exists because individuals have implicit as well as explicit attitudes, which are impacted differentially by stimuli and elicit dissimilar behavioral responses and thus have different implications for business ethics policies. Two longitudinal studies are conducted to better understand the impact of an individual’s dual attitudes on preferences and choice. Our findings support the presence of dual attitudes in consumers. Explicit attitudes are found to be easily influenced by the nature of the stimuli. On the other hand, implicit attitudes are relatively unaffected by the nature of the stimuli present and remain relatively constant. Based on the findings, implicit attitudes guide behavior and determine an individual’s preferences. Even though explicit attitudes react to the stimuli presented, our findings suggest they have no impact on the choice of consumers. These findings improve the understanding of ethical consumption, provide a reason as to why the attitude–behavior gap exists, provide a foundation for future researchers and help firms better understand the impact of perceived business on creating a behavioral shift in ethical consumption.

Ethical workplace climate has been extensively researched in the for-profit context but neglected in nonprofits. Perhaps because nonprofits promote shared values, engage with people, and implement development interventions creating public good, they are considered implicitly ethical. This assumption has been questioned in recent studies. We attempted to develop a psychometrically valid scale measuring ethical workplace climate following a sequential research design to fill this gap. We interviewed 74 employees from 30 nonprofit organizations using the critical incident technique to generate statements (...) on ethical workplace climate. The statements generated were categorized with expert judges' help, followed by a survey of 507 nonprofit employees across India. The exploratory factor analysis (EFA) and subsequent confirmatory factor analysis (CFA) resulted in a 43-item scale, further reduced to 26 items using stepwise regression. Results of subsequent application of EFA and CFA confirmed a four-factor solution: self-interest, collegiality, internal legitimacy, and stewardship. A follow-up study of 243 members of nonprofit organizations confirmed the hypothesized relationships that ethical work climate has a significant effect on affective commitment and job engagement. Finally, we discussed our findings along theoretical contributions, implications, limitations, and future direction. (shrink)

In response to a crisis, policymakers face the decision of whether to enumerate specific actions the public must do or, instead, to aim at an overall outcome while leaving room open for choice. This essay evaluates the merits and demerits of crisis response that leaves room open for choice, with a particular focus on pandemic response. I evaluate two approaches: trades and offsets. Trades allow individuals or groups to exchange protection against harm or entitlement to engage in risky activity. Offsets (...) allow the same actors to pay to mitigate the effects of decisions that increase risk for others. Choice-friendly approaches can free people to better align their actions with their values, harness local knowledge for better social outcomes, and act as natural experiments. However, they also are subject to objections, including negative externalities, agency problems, exploitation, and exacerbating inequality. (shrink)

Health policy is only one part of social policy. Although spending administered by the health sector constitutes a sizeable fraction of total state spending in most countries, other sectors such as education and transportation also represent major portions of national budgets. Additionally, though health is one important aspect of economic and social activity, people pursue many other goals in their social and economic lives. Similarly, direct benefits—those that are immediate results of health policy choices—are only a small portion of the (...) overall impact of health policy. This chapter considers what weight health policy should give to its “spill-over effects,” namely non-health and indirect benefits. (shrink)

This article examines a fundamental question of justice in global health. Is it ethically preferable to provide a larger number of people with cheaper treatments that are less effective (or more toxic), or to restrict treatments to a smaller group to provide a more expensive but more effective or less toxic alternative? We argue that choosing to provide less effective or more toxic interventions to a larger number of people is favored by the principles of utility, equality, and priority for (...) those worst-off. Advocates are mistaken to demand that medical care provided in low-income and middle-income countries should be the same as in high-income countries. (shrink)

This paper takes a novel approach to the active bioethical debate over whether advance medical directives have moral authority in dementia cases. Many have assumed that advance directives would lack moral authority if dementia truly produced a complete discontinuity in personal identity, such that the predementia individual is a separate individual from the postdementia individual. I argue that even if dementia were to undermine personal identity, the continuity of the body and the predementia individual’s rights over that body can support (...) the moral authority of advance directives. I propose that the predementia individual retains posthumous rights over her body that she acquired through historical embodiment in that body, and further argue that claims grounded in historical embodiment can sometimes override or exclude moral claims grounded in current embodiment. I close by considering how advance directives grounded in historical embodiment might be employed in practice and what they would and would not justify. (shrink)

Este ensaio pretende explorar a hipótese de que haveria subjacente à indistinção criada na figura do monstro de Frankenstein, entre o humano e não-humano, um princípio mimético que embora não necessariamente implique o monstruoso, foi a ele associado. Entender que algo que imita a perfeição de um ser humano, em todas as suas características, sobretudo linguísticas, seria um ser humano, ou seja, ter a imitação como critério para se definir o humano, é colocado em questão no romance de Mary Shelley.

Recognising that offers of payment to research participants can serve various purposes—reimbursement, compensation and incentive—helps uncover differences between participants, which can justify differential payment of participants within the same study. Participants with different study-related expenses will need different amounts of reimbursement to be restored to their preparticipation financial baseline. Differential compensation can be acceptable when some research participants commit more time or assume greater burdens than others, or if inter-site differences affect the value of compensation. Finally, it may be permissible (...) to offer differential incentive payments if necessary to advance the goals of a study. We encourage investigators and Institutional Review Boards to think about whether to offer payment, in what amounts and for what purpose, and also to consider whether differential payment can help promote the scientific and ethical goals of clinical research.

Allocation of very scarce medical interventions such as organs and vaccines is a persistent ethical challenge. We evaluate eight simple allocation principles that can be classified into four categories: treating people equally, favouring the worst-off, maximising total benefits, and promoting and rewarding social usefulness. No single principle is sufficient to incorporate all morally relevant considerations and therefore individual principles must be combined into multiprinciple allocation systems. We evaluate three systems: the United Network for Organ Sharing points systems, quality-adjusted life-years, and (...) disability-adjusted life-years. We recommend an alternative system—the complete lives system—which prioritises younger people who have not yet lived a complete life, and also incorporates prognosis, save the most lives, lottery, and instrumental value principles.

This article proposes a novel strategy, one that draws on insights from antidiscrimination law, for addressing a persistent challenge in medical ethics and the philosophy of disability: whether health systems can consider quality of life without unjustly discriminating against individuals with disabilities. It argues that rather than uniformly considering or ignoring quality of life, health systems should take a more nuanced approach. Under the article's proposal, health systems should treat cases where quality of life suffers because of disability-focused exclusion or (...) injustice differently from cases where lower quality of life results from laws of nature, resource scarcity, or appropriate tradeoffs. Decisionmakers should ignore quality-of-life losses that result from injustice or exclusion when ignoring them would improve the prospects of individuals with disabilities; in contrast, they should consider quality-of-life losses that are unavoidable or stem from resource scarcity or permissible tradeoffs. On this proposal, while health systems should not amplify existing injustice against individuals with disabilities, they are not required to altogether ignore the potential effects of disability on quality of life.

This chapter discusses how justice applies to public health. It begins by outlining three different metrics employed in discussions of justice: resources, capabilities, and welfare. It then discusses different accounts of justice in distribution, reviewing utilitarianism, egalitarianism, prioritarianism, and sufficientarianism, as well as desert-based theories, and applies these distributive approaches to public health examples. Next, it examines the interplay between distributive justice and individual rights, such as religious rights, property rights, and rights against discrimination, by discussing examples such as mandatory (...) treatment and screening. The chapter also examines the nexus between public health and debates concerning whose interests matter to justice (the “scope of justice”), including global justice, intergenerational justice, and environmental justice, as well as debates concerning whether justice applies to individual choices or only to institutional structures (the “site of justice”). The chapter closes with a discussion of strategies, including deliberative and aggregative democracy, for adjudicating disagreements about justice. (shrink)

The assumption that procuring more organs will save more lives has inspired increasingly forceful calls to increase organ procurement. This project, in contrast, directly questions the premise that more organ transplantation means more lives saved. Its argument begins with the fact that resources are limited and medical procedures have opportunity costs. Because many other lifesaving interventions are more cost‐effective than transplantation and compete with transplantation for a limited budget, spending on organ transplantation consumes resources that could have been used to (...) save a greater number of other lives. This argument has not yet been advanced in debates over expanded procurement and could buttress existing concerns about expanded procurement. To support this argument, I review existing empirical data on the cost‐effectiveness of transplantation and compare them to data on interventions for other illnesses. These data should motivate utilitarians and others whose primary goal is maximizing population‐wide health benefits to doubt the merits of expanding organ procurement. I then consider two major objections: one makes the case that transplant candidates have a special claim to medical resources, and the other challenges the use of cost‐effectiveness to set priorities. I argue that there is no reason to conclude that transplant candidates’ medical interests should receive special priority, and that giving some consideration to cost‐effectiveness in priority setting requires neither sweeping changes to overall health priorities nor the adoption of any specific, controversial metric for assessing cost‐effectiveness. Before searching for more organs, we should first ensure the provision of cost‐effective care. (shrink)

ExcerptThe following essay is an investigation into the nature of the contract, the way in which the contract indexes “right” and equality, and the textual and historical expressions—as well as echoes—that this has taken from Thomas Hobbes to Karl Marx.1 The opening set of conceptual remarks will lead to a reading of Hobbes's Leviathan and Marx's On the Jewish Question, with the intent of arguing that both texts were concerned with theoretically explicating the relationship between right and equality, germane to (...) which was the problematic of the “nation,” which was itself conceived via the “Jewish question.” It will be argued….

ExcerptModernity has been identified with progress and with the idea of progress.1 The identification of progress as fact and idea conceal a two-fold problematic: the nature of time and the subject being characterized. If progress is its characteristic, the subject cannot in turn be said to be in fact progressing, and if it is not, it will be indiscernible from regression. This is not unrelated to modernity construing itself as distinct, distinguishing itself from the past while, at the same time, (...) defining such distinction only in the possibility of (self-)cancellation, i.e., opening an unanticipated future.

Robustness arguments hold that hypotheses are more likely to be true when they are confirmed by diverse kinds of evidence. Robustness arguments require the confirming evidence to be independent. We identify two kinds of independence appealed to in robustness arguments: ontic independence —when the multiple lines of evidence depend on different materials, assumptions, or theories—and probabilistic independence. Many assume that OI is sufficient for a robustness argument to be warranted. However, we argue that, as typically construed, OI is not a (...) sufficient independence condition for warranting robustness arguments. We show that OI evidence can collectively confirm a hypothesis to a lower degree than individual lines of evidence, contrary to the standard assumption undergirding usual robustness arguments. We employ Bayesian networks to represent the ideal empirical scenario for a robustness argument and a variety of ways in which empirical scenarios can fall short of this ideal. (shrink)

The value-free ideal for science holds that values should not influence the core features of scientific reasoning. We defend the difference-to-inference model of value-permeation, which holds that value-permeation in science is problematic when values make a difference to the inferences made about a hypothesis. This view of value-permeation is superior to existing views, and it suggests a corresponding maxim—namely, that scientists should strive to eliminate differences to inference. This maxim is the basis of a novel value-free ideal for science. -/- (...) . (shrink)

This chapter argues that rather than viewing transparency as a right, we should regard it as a finite resource whose allocation involves tradeoffs. It then argues that those tradeoffs should be resolved by using a multi-principle approach to distributive justice. The relevant principles include maximizing welfare, maximizing autonomy, and giving priority to the worst off. Finally, it examines some of the implications for law of recognizing the tradeoffs presented by transparency proposals.

This chapter explores two questions in detail: How should we determine the threshold for costs that individuals are asked to bear through insurance premiums or care-related out-of-pocket costs, including user fees and copayments? and What is an adequate relationship between costs and benefits? This chapter argues that preventing impoverishment is a morally more urgent priority than protecting households against income fluctuations, and that many health insurance plans may not adequately protect individuals from health care costs that threaten to drop their (...) financial status below a decent minimum. A design that places greater emphasis on preventing impoverishment and finances the achievement of that goal by reducing unnecessary subsidies to better-off households would better accord with a sufficientarian approach to health care. -/- .

The value-free ideal in science has been criticised as both unattainable and undesirable. We argue that it can be defended as a practical principle guiding scientific research even if the unattainability and undesirability of a value-free end-state are granted. If a goal is unattainable, then one can separate the desirability of accomplishing the goal from the desirability of pursuing it. We articulate a novel value-free ideal, which holds that scientists should act as if science should be value-free, and we argue (...) that even if a purely value-free science is undesirable, this value-free ideal is desirable to pursue.

We propose six guideposts that states and hospitals should follow to respect disability rights when designing policies for the allocation of scarce, lifesaving medical treatments. Four relate to criteria for decisions. First, do not use categorical exclusions, especially ones based on disability or diagnosis. Second, do not use perceived quality of life. Third, use hospital survival and near-term prognosis (e.g., death expected within a few years despite treatment) but not long-term life expectancy. Fourth, when patients who use ventilators in their (...) daily lives (e.g., home ventilation) present to acute care hospitals, their personal ventilators should not be reallocated to other patients. Fifth, designate triage officers to assess patients individually on the basis of objective medical evidence, not stereotypes or assumptions. Sixth, include disability rights advocates in policy development and dissemination. (shrink)

Technological and societal changes have made downward social and economic mobility a pressing issue in real-world politics. This article argues that a Rawlsian society would not provide any special protection against downward mobility, and would act rightly in declining to provide such protection. Special treatment for the downwardly mobile can be grounded neither in Rawls’s core principles—the basic liberties, fair equality of opportunity, and the difference principle—nor in other aspects of Rawls’s theory. Instead, a Rawlsian society is willing to sacrifice (...) particular individuals’ ambitions and plans for the achievement of justice, and offers those who lose out from justified change no special solicitude over and above the general solicitude extended to all. Rather than guaranteeing the maintenance of any particular individual or group’s economic position, it provides all of its members—the upwardly mobile, the downwardly mobile, and the immobile—a form of security that is at once more generous and more limited: that they will receive the liberties, opportunities, and resources promised by the principles of justice.

Brown and Pooley’s ‘dynamical approach’ to physical theories asserts, in opposition to the orthodox position on physical geometry, that facts about physical geometry are grounded in, or explained by, facts about dynamical fields, not the other way round. John Norton has claimed that the proponent of the dynamical approach is illicitly committed to spatiotemporal presumptions in ‘constructing’ space-time from facts about dynamical symmetries. In this article, I present an abstract, algebraic formulation of field theories and demonstrate that the proponent of (...) the dynamical approach is not committed, in special relativity, to the illicit presumptions to which Norton refers.

Four ethical values — maximizing benefits, treating equally, promoting and rewarding instrumental value, and giving priority to the worst off — yield six specific recommendations for allocating medical resources in the Covid-19 pandemic: maximize benefits; prioritize health workers; do not allocate on a first-come, first-served basis; be responsive to evidence; recognize research participation; and apply the same principles to all Covid-19 and non–Covid-19 patients.

Supersymmetry (SUSY) is a proposed symmetry between bosons and fermions. The structure of the space of SUSY generators is such that the distinction between internal and spacetime symmetries is blurred. As a result, there are two viable candidates for the correct spacetime setting for a flat supersymmetric field theory---Minkowski spacetime and superspace. an extension of four- dimensional Minkowski spacetime to include (at least) four new dimensions, coordinatised by mathematical objects known as supernumbers. These objects are, in one significant way, quite (...) different from real or complex number---some of them have the property that their order of multiplication makes a difference; in mathematical terms, they are said to have nontrivial commutation properties. This paper argues for two theses: first, that one standard set of arguments, related to universality of symmetry behaviour, that motivate a particular choice of spacetime structure in familiar spacetime theories motivates the choice of superspace as the appropriate spacetime for SUSY field theories. And second, that the metaphysical utility of the concept of spacetime requires more than just the satisfaction of this universality condition; in supersymmetric theories, the spacetime concept is not as useful as in special relativity.

Recent work in the physics literature demonstrates that, in particular classes of rotating spacetimes, physical light rays in general do not traverse null geodesics.

Initial vaccine allocations for the coronavirus disease 2019 (COVID-19) will be limited. It is crucial to assess the ethical values associated with different methods of allocation, as well as important scientific and practical questions. This Viewpoint identifies three ethical values, benefiting people and limiting harm; prioritizing disadvantaged populations; and equal concern for all. It then explains why these values support prioritizing three groups: health care workers; other essential workers and people in high-transmission settings; and people with medical vulnerabilities associated with (...) poorer COVID-19 outcomes. In contrast, two other groups, people over 65 without medical vulnerabilities and participants in clinical research, present more complex ethical questions. This prioritization also encompasses valuing direct benefits to vaccinated individuals, indirect benefits to individuals protected from spread of infection, and indirect health and socioeconomic benefits to those protected from harm as health system and societal functioning improve. Vaccine allocation that recognizes important ethical values and avoids arbitrariness, waste, and corruption can ensure that the distribution of a COVID-19 vaccine is both fair and perceived as fair.

Recent disputes over whether older people should pay more for health insurance, or receive lower priority for transplantable organs, highlight broader disagreements regarding the legality of using age-based criteria in health care. These debates will likely intensify given the changing age structure of the American population and the turmoil surrounding the financing of American health care. This Article provides a comprehensive examination of the legality and normative desirability of age-based criteria. I defend a distributive justice approach to age-based criteria and (...) contrast it with two prevailing theoretical approaches to age-based criteria, nondiscrimination and discretion. I propose a detailed normative framework for the use of age-based criteria in health care, the lifetime justice approach, that considers the future life patients can gain from treatment and the past years of life they already have experienced. -/- This paper is available by open access from the Boston College Law School Digital Commons.

Phase transitions are an important instance of putatively emergent behavior. Unlike many things claimed emergent by philosophers, the alleged emergence of phase transitions stems from both philosophical and scientific arguments. Here we focus on the case for emergence built from physics, in particular, arguments based upon the infinite idealization invoked in the statistical mechanical treatment of phase transitions. After teasing apart several challenges, we defend the idea that phase transitions are best thought of as conceptually novel, but not ontologically or (...) explanatorily irreducible to finite physics; indeed, by looking at ongoing work on “smooth phase transitions” we even suggest that they’re not even conceptually novel. In the case of renormalization group theory, consideration of infinite systems and their singular behavior provides a central theoretical tool, but this is compatible with an explanatory reduction. Phase transitions may be “emergent” in some sense of this protean term, but not in a sense that is incompatible with the reductionist project broadly construed. (shrink)
