Usually the Lorentz transformations are derived from the conservation of the spacetime interval. We propose here a way of obtaining spacetime transformations between two inertial frames directly from symmetry, the isotropy of the space and principle of relativity. The transformation is uniquely defined except for a constant e, that depends only on the process of synchronization of clocks inside each system. Relativistic velocity addition is obtained, and it is shown that the set of velocities is a bounded symmetric domain. If (...) e=0, Galilean transformations are obtained. If e>0, the speed 1/√e and a spacetime interval are conserved. By assuming constancy of the speed of light, we get e=1/c 2 and the transformation between the frames becomes the Lorentz transformation. If e<0, a proper speed and a Hilbertian norm are conserved.

The first principle of the Nuremberg Code requires the informed consent of the subject. Proxy consent was not addressed until the Declaration of Helsinki. U.S. policies regarding consent for the participation of children in research would not be finalized for almost two more decades in subpart D of the federal regulations that govern the participation of subjects in research. In October 2000, the Children's Health Act was passed. Title X required the Secretary of the Department of Health and Human Services (...) to conduct a review of the regulations under subpart D and “to consider any modifications necessary to ensure the adequate and appropriate protection of children participating in research, and report the findings of the Secretary to Congress.” In this article, I provide a brief overview of the current informed consent requirements in pediatric research, which include requirements for parental permission and the child's assent. I then examine the moral bases for these requirements; whether the current policies are consistent with these moral foundations; and if not, how the policies ought to be modified. a. (shrink)

In 1999, a case was described on national television in which a woman had enlisted onto an international bone marrow registry with the altruistic desire to offer her bone marrow to some unidentified individual in need of a transplant. The potential donor then was notified that she was a compatible match with someone dying from leukemia and gladly donated her marrow, which cured the recipient of the disease. Years later, though, the recipient developed end-stage renal disease, a consequence of the (...) high-dose chemotherapy she received earlier to destroy her stem cells and prepare her for the bone marrow transplant. Finding a suitable donor for a kidney transplant proved extremely difficult. Desperate, she requested that the donor registry personnel help her locate the individual who earlier was determined to be a compatible donor and asked this now-identifiable individual to consider donating one of her two normally functioning kidneys for a kidney transplant.

American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) recently provided two recommendations about predictive genetic testing of children. The Clinical Sequencing Exploratory Research Consortium's Pediatrics Working Group compared these recommendations, focusing on operational and ethical issues specific to decision making for children. Content analysis of the statements addresses two issues: (1) how these recommendations characterize and analyze locus of decision making, as well as the risks and benefits of testing, and (2) whether the guidelines conflict or (...) come to different but compatible conclusions because they consider different testing scenarios. These statements differ in ethically significant ways. AAP/ACMG analyzes risks and benefits using best interests of the child and recommends that, absent ameliorative interventions available during childhood, clinicians should generally decline to order testing. Parents authorize focused tests. ACMG analyzes risks and benefits using the interests of the child and other family members and recommends that sequencing results be examined for additional variants that can lead to ameliorative interventions, regardless of age, which laboratories should report to clinicians who should contextualize the results. Parents must accept additional analysis. The ethical arguments in these statements appear to be in tension with each other. (shrink)

The advanced donation program was proposed in 2014 to allow an individual to donate a kidney in order to provide a voucher for a kidney in the future for a particular loved one.

This book examines the ethical issues in pediatric medical research. It argues that policies and practices on the participation of children must focus primarily on minimizing risks. It offers specific recommendations to revise Subpart D of the federal regulations to provide greater protection where necessary and remove obstacles that do not provide additional protection but interfere with access. The book is divided into four sections. Section 1 focuses on the issue of access versus protection in pediatric research. Section 2 deals (...) with challenges to regulations. Section 3 discusses the strengths and limits of current regulations, while different case studies are examined in Section 4. (shrink)

Alexander Moritzi is one of the most obscure figures in the early history of evolutionary thought. Best known for authoring a flora of Switzerland, Moritzi also published Réflexions sur l’espèce en histoire naturelle, a remarkable book about evolution with an overtly materialist viewpoint. In this work, Moritzi argues that the generally accepted line between species and varieties is artificial, that varieties can over time give rise to new species, and that deep time and turnover of species in the fossil record (...) clearly support an evolutionary interpretation of biological diversity. Moritzi was also a gradualist and viewed relationships between taxa as best represented by a ramifying tree. Although Réflexions was the first full book to be written on the topic of evolution following Lamarck’s Philosophie zoologique, Moritzi’s evolutionist contribution was stillborn, read by almost no one in his lifetime and ultimately absent from the many historiographies of evolutionary thought. This is unfortunate since many of the arguments Moritzi marshaled on behalf of an evolutionary explanation of life can be found in subsequent transmutationist writings by Frédéric Gérard, Robert Chambers, Henri Lecoq, Baden Powell, Charles Naudin, Herbert Spencer, Alfred Russel Wallace, and Charles Darwin—none of whom is likely to have ever known of the existence of Réflexions. Finally, Moritzi’s arguments, along with those found in Darwin’s private essay on evolution of the same year, provide an excellent window into the state of evolutionary thought and debate over the nature of species at the beginning of the 1840s.

ABSTRACTIn 1994, the Committee on Assessing Genetic Risks of the Institute of Medicine published their recommendations regarding the ethical issues raised by advances in genetics. One of the Committee's recommendation was to inform women when test results revealed misattributed paternity, but not to disclose this information to the women's partners. The Committee's reason for withholding such information was that “'genetic testing should not be used in ways that disrupt families”. In this paper, I argue that the Committee's conclusion in favour (...) of nondisclosure to the male partner is unethical. I argue that both parties ought to be informed. (shrink)

The fundamental principle of modern-day bioethics is that “the competent adult has the right to accept or refuse all medical care, including life-saving medical care,” a principle that has been upheld by the U.S. Supreme Court in Bouvia v. Superior Court ) and Cruzan v. Director, Missouri Department of Health ). If the adult lacks decision-making capacity, a surrogate can speak on his or her behalf. The adult may have chosen his or her surrogate through an advance directive; if not, (...) laws assign guardianship based on a hierarchy of relationships. Surrogates are expected.. (shrink)

The term “exceptionalism” was introduced into health care in 1991 when Bayer described “HIV exceptionalism” as the policy of treating the human immunodeficiency virus different from other infectious diseases, particularly other sexually transmitted diseases. It was reflected in the following practices: pre- and post-HIV test counseling, the development of specific separate consent forms for HIV testing, and stringent requirements for confidentiality of HIV test results. The justification for these practices was the belief that testing was essential for prevention and that (...) patients might not seek HIV testing if confidentiality were not guaranteed. Confidentiality was believed to be particularly important given the degree of discrimination and stigmatization associated with the illness. Anonymous testing was a further step in ensuring strict confidentiality, even though such a practice prevented public officials from contacting partners and others who were at risk. (shrink)

The argument for children's rights in health care has been long in the making. The success of this position is reflected in the 1995 American Academy of Pediatrics recommendations for the role of children in health care decisionmaking, which suggest that children be given greater voice as they mature. But there are good moral and practical reasons for exercising caution in these health care situations, especially when the child and parents disagree. Parents need the moral and legal space within which (...) to make decisions that will facilitate their child's long‐term autonomy, not only her present‐day autonomy. Moreover, third‐party intrusion, by physicians or the state, should be resisted unless negligent and abusive decisions are in the making. (shrink)

Virtually every infant in the United States (U.S.) undergoes a heel stick within the first week of life to test for a variety of metabolic, endocrine, and hematological conditions as part of state-run universal newborn screening (NBS) programs. In the U.S., NBS began in the 1960s for phenylketonuria (PKU), a metabolic condition that causes intellectual disability if left untreated. I review the history of how NBS came to be a mandatory public health program that did not require parental consent1 and (...) examine whether the policy was morally justifiable. I then examine how three changes to NBS programs are prompting a re-evaluation of the mandatory nature of NBS. The three changes are: (1) the implementation of .. (shrink)

Healthcare decision making for children has adopted the best interest of the child standard, a principle originally employed by judges to adjudicate child placement in the case of parental death, divorce, or incompetence. Philosophers and medical ethicists have argued whether the best interest principle is a guidance principle (informing parents on how they should make healthcare decisions for their child), an intervention principle (deciding the limits of parental autonomy in healthcare decision making), or both. Those who defend it as only (...) a guidance principle often cite the harm principle as the appropriate intervention principle. In this article, I challenge current use of the best interest principle in pediatric decision making as a guidance principle and as an intervention principle. I propose a model that I call constrained parental autonomy, which focuses on promoting and protecting the child’s primary goods or basic needs. I show that constrained parental autonomy can serve as both a guidance principle and an intervention principle in making decisions. I conclude by examining a case study involving bone marrow donation by a young child to her sister. (shrink)

In February 1997, the Committee on Bioethics of the American Academy of Pediatrics updated its position on religious exemptions to medical care. In its earlier statement, the committee noted that forty-four states have religious exemptions to the child abuse and neglect statutes, and they argued for the repeal of these exemptions. The committee did not indude in its statement a position on religious exemptions to childhood immunization requirements that exist in forty-eight states, although this issue was discussed in committee meetings. (...) In its revised statement, the committee concluded that “The AAP does not support the stringent application of medical neglect laws when children do not receive recommended immunizations.” In this paper, we consider whether failure to immunize one's child is a form of medical neglect and, if so, whether states should repeal their religious exemptions to the immunization statutes. We argue that failure to vaccinate a child properly is medical neglect. (shrink)

In August 2000, Arthur Matas and his colleagues de scribed a protocol in which their institution began to accept as potential donors, individuals who came to the University of Minnesota hospital offering to donate a kidney to any patient on the waiting list.

The definition of death was clearer one hundred years ago than it is today. People were declared dead if diagnosed with permanent cessation of both cardio‐circulatory function and respiratory function. But the definition has been muddled by the development of new technologies and interventions—first by cardiopulmonary resuscitation and ventilators, which were introduced in the mid‐twentieth century, and now by extracorporeal membrane oxygenation, which creates the ability to keep oxygenated blood circulating, with or without a beating heart or functioning lungs. In (...) Defining Death: The Case for Choice, Robert Veatch and I argue that the definition of death should focus on “what change in a human being is so fundamental that we can say the individual is no longer with us as a member of the human community bearing rights such as the right not to be killed.” We assert that this decision is a normative issue about which different stakeholders may believe that different changes are fundamental, and we therefore propose that the optimal policy solution may be to allow stakeholders to choose their own definition within a reasonable range of options. There are three caveats that need to be highlighted regarding this approach. (shrink)

The traditional living donor was very healthy. However, as the supply-demand gap continues to expand, transplant programs have become more accepting of less healthy donors. This paper focuses on the other extreme, asking whether and when individuals who have life-limiting conditions should be considered for living organ donation. We discuss ethical issues raised by 1) donation by individuals with progressive severe debilitating disease for whom there is no ameliorative therapy; and 2) donation by individuals who are imminently dying or would (...) die by the donation process itself.

The "best interest of the child" standard is central to both pediatric bioethics and the child rights community. In pediatric bioethics in the United States, the best interest of the child standard is cited as the guidance principle for parental decision-making.1 Likewise, in the child rights community, the best interest of the child standard is "of paramount consideration" ). Both approaches also recognize parental rights and responsibilities and support a role for the maturing child in the decision-making process. Why, then, (...) do members of the pediatric bioethics community and the child rights communities not speak the same language?This article was developed out of... (shrink)

In this paper, I defend Rudolf Carnap's Principle of Tolerance from an accusation, due to Michael Friedman, that it is self-defeating by prejudicing any debate towards the logically stronger theory. In particular, Friedman attempts to show that Carnap's reconstruction of the debate between classicists and intuitionists over the foundations of mathematics in his book The Logical Syntax of Language, is biased towards the classical standpoint since the metalanguage he constructs to adjudicate between the rival positions is fully classical. (...) I argue that this criticism is mistaken on two counts: (1) it fails to fully appreciate the freedom with regard to the construction of linguistic frameworks that Carnap intended his Principle to embody, and (2) Friedman's objection underestimates the extent to which the evaluation of a framework is task-relative. I conclude that Tolerance is not self-undermining in the way that Friedman claims it is. While this is a restricted conclusion -- and is not a vindication of Carnap's views on logic and mathematics tout court -- it nonetheless suggests that his tolerant perspective has been dismissed too quickly, even by his supporters.

: The past decade has witnessed the emergence of novel methods to increase the number of living donors. Although such programs are not likely to yield high volumes of organs, some transplant centers have gone to great lengths to establish one or more of them. I discuss some of the ethical and policy issues raised by five such programs: (1) living-paired and cascade exchanges; (2) unbalanced living-paired exchanges; (3) list-paired exchanges; (4) nondirected donors; and (5) nondirected donors catalyzing cascade exchanges. (...) I argue that living-paired and cascade exchanges are ethically sound, but will lead to only a few additional transplants. Unbalanced exchanges and list-paired exchanges raise ethical issues that should limit their permissibility. Nondirected donations can be ethically sound with adherence to strict eligibility criteria and fair allocation procedures. Nondirected donors catalyzing cascade exchanges can be ethically sound provided that individuals with blood types O and B are not made worse off. (shrink)

: Subpart D of 45 CFR 46 focuses on research involving children. Section 46.407 addresses research that is not otherwise approvable. The research is not otherwise approvable because either (1) it seeks to enroll healthy children, but offers no prospect of direct benefit and entails more than minimal risk; or (2) it seeks to enroll children with a disorder or condition, but offers no prospect of direct benefit and entails more than a minor increase over minimal risk. According to 46.407, (...) such research can be permissible if it is approved by a panel of experts. Prior to 2000, only two 407 panels had been convened, but in 2001, the Office for Human Research Protections received more than 20 protocols for 407 review. The first, entitled "Precursors to Diabetes in Japanese American Youth," serves here as a case study in human subject protections. (shrink)
