Telomeres are protective caps for chromosome ends that are essential for genome stability. Broken chromosomes missing a telomere will not be maintained unless the chromosome is ‘healed’ with the formation of a new telomere. Chromosome healing can be a programmed event following developmentally regulated chromosome fragmentation, or it may occur spontaneously when a chromosome is accidentally broken. In this article we discuss the consequences of telomere loss and the possible mechanisms that the enzyme telomerase employs to form telomeres de novo (...) on broken chromosome ends. (shrink)

Computer and video games have become nearly ubiquitous among individuals in industrialized nations, and they have received increasing attention from researchers across many areas of scientific study. However, relatively little attention has been given to Massively-Multiplayer Online Games . The unique social context of MMOGs raises ethical questions about how communication occurs and how conflict is managed in the game world. In order to explore these questions, we compare the social context in Blizzard’s World of Warcraft and Disney’s Toontown, focusing (...) on griefing opportunities in each game. We consider ethical questions from the perspectives of players, game companies, and policymakers. (shrink)

Public discourse on race-specific medicine typically erects a wall between the scientific use of race as a biological category and the ideological battle over race as a social identity. Scientists often address the potential for these therapeutics to reinforce a damaging understanding of “race” with precautions for using them rather than questioning their very development. For example, Esteban Gonzalez Burchard, an associate professor of medicine and biopharmaceutical sciences at the University of California, San Francisco, states, “We do see racial differences (...) between populations and shouldn’t just close our eyes. Unfortunately, race is a politically charged topic, and there will be evildoers. But the fear should not outweigh the benefit of looking.” Although it is recognized that ideology influences the social meaning of race, it is usually assumed that there is a separate, prior scientific understanding of race that is not contaminated by politics.

The scientific validity of racial categories has been the subject of debate among population geneticists, evolutionary biologists, and physical anthropologists for several decades. After World War II, the rejection of eugenics, which had supported sterilization laws and other destructive programs in the United States, generated a compelling critique of the biological basis of race. The classification of human beings into distinct biological “races” is a relatively recent invention propped up by deeply flawed evidence and historically providing the foundation of racist (...) ideology and inequities of power. Social scientists’ conclusion that race is socially constructed was confirmed by genomic studies of human variation, including the Human Genome Project, showing high levels of genetic similarity within the human species. Some scholars came to believe that the science of human genetic diversity would replace race as the preeminent means of grouping people for scientific purposes. (shrink)

This chapter provides a historical reconstruction of how Alfred Schutz’s American writings were critically engaged by the feminist sociologists Dorothy E. Smith and Patricia Hill Collins. Schutz’s articulation of a phenomenological sociology in relation to, among others, the sociology of Talcott Parsons and the philosophies of science of Ernest Nagel and Carl G. Hempel proved fruitful to Smith in the development of her feminist standpoint theory in her 1987 The Everyday World as Problematic: A Feminist Sociology. Collins likewise draws (...) on Schutz’s writing in the development of her own standpoint theory in her 1986 paper “Learning from the Outsider Within: The Sociological Significance of Black Feminist Thought,” but in a way that addresses some of her own concerns with Smith’s feminist sociology. As I hope to show with the recovery of this underappreciated history, the critical insights of Smith and Collins with regard to the possible uses and limits of phenomenology for feminist theorizing, are still valuable today.

The article argues that Marx’s use of the concept of ideology in The German Ideology is incidental to a sustained critique of how those he described as the German ideologists think and reason about society and history and that this critique is not simply of an idealist theory that represents society and history as determined by consciousness but of methods of reasoning that treat concepts, even of those of political economy, as determinants. His view of how consciousness is determined historically (...) by our social being does not envisage some kind of mechanical transfer of class status to class consciousness. Rather, he works with an epistemology that takes the concepts foundational to political economy as expressions or reflections of the social relations of a mode of production. The difference between ideology and science is the difference between treating those concepts as the primitives of theory and treating them as sites for exploring the social relations that are expressed in them. Thus, the historical rather than further undermining claims to knowledge, provides both the conditions under which knowledge is possible and its limitations. (shrink)

Withholding or withdrawing life-saving ventilators can become necessary when resources are insufficient. In the USA, such rationing has unique social justice dimensions. Structural elements of dominant allocation frameworks simultaneously advantage white communities, and disadvantage Black communities—who already experience a disproportionate burden of COVID-19-related job losses, hospitalisations and mortality. Using the example of New Jersey’s Crisis Standard of Care policy, we describe how dominant rationing guidance compounds for many Black patients prior unfair structural disadvantage, chiefly due to the way creatinine and (...) life expectancy are typically considered.We outline six possible policy options towards a more just approach: improving diversity in decision processes, adjusting creatinine scores, replacing creatinine, dropping creatinine, finding alternative measures, adding equity weights and rejecting the dominant model altogether. We also contrast these options with making no changes, which is not a neutral default, but in separate need of justification, despite a prominent claim that it is simply based on ‘objective medical knowledge’. In the regrettable absence of fair federal guidance, hospital and state-level policymakers should reflect on which of these, or further options, seem feasible and justifiable.Irrespective of which approach is taken, all guidance should be supplemented with a monitoring and reporting requirement on possible disparate impacts. The hope that we will be able to continue to avoid rationing ventilators must not stand in the way of revising guidance in a way that better promotes health equity and racial justice, both to be prepared, and given the significant expressive value of ventilator guidance.

Pandemic plans are increasingly attending to groups experiencing health disparities and other social vulnerabilities. Although some pandemic guidance is silent on the issue, guidance that attends to socially vulnerable groups ranges widely, some procedural (often calling for public engagement), and some substantive. Public engagement objectives vary from merely educational to seeking reflective input into the ethical commitments that should guide pandemic planning and response. Some plans that concern rationing during a severe pandemic recommend ways to protect socially vulnerable groups without (...) prioritizing access to scarce resources based on social vulnerability per se. The Minnesota Pandemic Ethics Project (MPEP), a public engagement project on rationing scarce health resources during a severe influenza pandemic, agrees and recommends an integrated set of ways to attend to the needs of socially vulnerable people and avoid exacerbation of health disparities during a severe influenza pandemic. Among other things, MPEP recommends: 1. Engaging socially vulnerable populations to clarify unique needs and effective strategies; 2. Engaging socially vulnerable populations to elicit ethical values and perspectives on rationing; 3. Rejecting rationing based on race, socioeconomic class, citizenship, quality of life, length of life-extension and first-come, first-served; 4. Prioritizing those in the general population for access to resources based on combinations of risk (of death or severe complications from influenza, exposure to influenza, transmitting influenza to vulnerable groups) and the likelihood of responding well to the resource in question. 5. Protecting critical infrastructures on which vulnerable populations and the general public rely; 6. Identifying and removing access barriers during pandemic planning and response; and 7. Collecting and promptly analyzing data during the pandemic to identify groups at disproportionate risk of influenza-related mortality and serious morbidity and to optimize the distribution of resources.

This article addresses three questions concerning the legal regulation of the use of race as a category in biomedical research: how does the law currently encourage the use of race in biomedical research?; how might the existing legal framework constrain its use?; and what should be the law's approach to race-based biomedical research? It proposes a social justice approach that aims to promote racial equality by discouraging the use of “race” as a biological category while encouraging its use as a (...) socio-political category to understand and investigate ways to eliminate disparities in health status, access to health care, and medical treatment.
