This month the American Journal of Bioethics examines the intersectionality of medicine, ethics, and race. In “Race, Power, and COVID-19: A Call for Advocacy Within Bioethics,” Mithani and colleagu...

What might we learn if the study of ethics focused less on hard cases and more on the practices of everyday life? In Everyday Ethics, Michael Lamb and Brian Williams gathered some of the world's leading scholars and practitioners of moral theology (including some Georgetown University Press authors) to explore that question in dialogue with anthropology and the social sciences. In a field largely begun by Michael Banner, contributors engage with and extend his ideas of ethics as it is practiced (...) in daily life. Crossing disciplinary boundaries, these scholars analyze the ethics of ordinary practices--from eating, learning, and loving the neighbor to borrowing and spending, using technology, and working in a flexible economy. Along the way, they consider the moral and methodological questions that emerge from this interdisciplinary dialogue and assess the implications for the future of moral theology. (shrink)

However, the functions of many cell wall synthesis genes, and the relationships among and the functions of cell wall components remain obscure. To better understand the patterns of cell wall accumulation and identify genes that act in grass (...) cell wall biosynthesis, we characterized 30 samples from aerial organs of rice at 10 developmental time points, 3-100 d post-germination. Within these samples, we measured 15 cell wall chemical components, enzymatic digestibility and 18 cell wall polysaccharide epitopes/ligands. We also used quantitative reverse transcription-PCR to measure expression of 50 glycosyltransferases, 15 acyltransferases and eight phenylpropanoid genes, many of which had previously been identified as being highly expressed in rice. Most cell wall components vary significantly during development, and correlations among them support current understanding of cell walls. We identified 92 significant correlations between cell wall components and gene expression and establish nine strong hypotheses for genes that synthesize xylans, mixed linkage glucan and pectin components. This work provides an extensive analysis of cell wall composition throughout rice development, identifies genes likely to synthesize grass cell walls, and provides a framework for development of genetically improved grasses for use in lignocellulosic biofuel production and agriculture.

The myf5 and myoD genes are implicated in the specification of vertebrate skeletal muscle. These genes have been thought to be functionally redundant because neonatal mice bearing homozygous null mutations in either gene show grossly normal muscle development. By analyzing the early embryonic development of the mutants, Michael Rudnicki and coworkers show that trunk muscle development is retarded in embryos bearing myf5 null mutations, while early limb and branchial arch muscle development is retarded by myoD null mutations.1 These results indicate (...) that the myoD and myf5 genes are not redundant but that each controls the early specification of distinct muscle cell lineages.

This article describes changes in conventions among social scientists undertaking research with children and young people over the last decade, and discusses the legal position and aspects of the ethics of research with people under eighteen. It includes three brief case examples which illustrate the nature of the issues involved and ethics committees' responses to them, and concludes that although differences of opinion remain, a consensus is emerging about the need to let young people speak for themselves, subject to appropriate (...) safeguards.

The Life and World of... biographies tell the life-story of key people from history - the part they played in shaping events, and how their lives touched other people.

Despite their ubiquity and widespread acceptance in contemporary education, formal grading systems are relatively recent innovations in the history and philosophy of education. Far from innocuous tools which aid the student’s academic development, grades and grading systems developed as ad hoc tools for ranking students against one another in academic competitions. This article examines the history of assessment, grades, and grading in light of the longer tradition of education and suggests alternative practices could better orient students toward the true, good, (...) beautiful, holy, healthy, and beneficial. By understanding how and why contemporary approaches to grades developed, classical educators will be equipped to mitigate the unintended and often unseen adverse consequences grades have on their students. Ultimately, this article seeks to liberate teachers and students to pursue the intrinsic goods of learning over against the fleeting and extrinsic rewards of making the grade. (shrink)

In many developing countries people and livestock suffer from preventable or curable diseases, and their agriculture is vulnerable to natural disasters. A considerable amount of technical aid is directed at alleviating these problems using modern science and technology, and yet most of these efforts either fail or even leave peasants and pastoralists worse off than before. In this paper we consider some of the problems that arise in relation to development projects, focusing our attention on the savannah regions of Africa (...) and, in particular, on the control of tsetse flies, which are the vectors of the African trypanosomiases, called nagana in cattle and sleeping sickness in people. We present a detailed case study of a project designed to enable a Maasai community in Kenya to carry out their own tsetse fly control. We examine the complex set of relationships and power structures that mediate the actions of the players in development: scientists, local communities, governmental and nongovernmental institutions, and development agencies. The purpose of this paper is not to present solutions to complex and difficult problems but rather to raise questions that should provide a framework for a debate concerning the role of science and technology in the development process.
