Moral psychology studies the features of cognition, judgement, perception and emotion that make human beings capable of moral action. Perspectives from feminist and race theory immensely enrich moral psychology. Writers who take these perspectives ask questions about mind, feeling, and action in contexts of social difference and unequal power and opportunity. These essays by a distinguished international cast of philosophers explore moral psychology as it connects to social life, scientific studies, and literature.

Our objective is to understand how parents and children perceive their roles in decision making about research participation. Forty-five children (ages 4-15 years) with or without a chronic condition and 21 parents were the participants. A semistructured interview assessed perceptions of up to 4 hypothetical research scenarios with varying levels of risk, benefit, and complexity. Children were also administered the Peabody Picture Vocabulary Test, Third Edition, to assess verbal ability, as a proxy for the child's cognitive development. The audiotaped interviews (...) were transcribed and analyzed for themes related to parent and child decision-making roles. Both parents and children varied in their perceptions of decision-making roles. Child perceptions of parental influence on decision making as knowledge-based increased with cognitive development, whereas perceptions of parental influence as power-based decreased. Both children and parents commented that they would collaborate with each other when making decisions. Collaborative decision making appeared to increase with cognitive development. These findings suggest that approaches to child assent and parent permission should consider the parent-child relationship and how children and families typically make decisions. Future research is necessary to explain variation in the process of research decision making across children and families, explore the role of collaboration on children's decision-making skills, and understand developmental trajectories and mechanisms related to research decision making.

The unique context of the rural setting provides special challenges to furnishing ethical healthcare to its approximately 62 million inhabitants. Although rural communities are widely diverse, most have the following common features: limited economic resources, shared values, reduced health status, limited availability of and accessibility to healthcare services, overlapping professional–patient relationships and care giver stress. These rural features shape common healthcare ethical issues, including threats to confidentiality, boundary issues, professional–patient relationship and allocation of resources. To date, there exists a limited (...) focus on rural healthcare ethics shown by the scarcity of rural healthcare ethics literature, rural ethics committees, rural focused ethics training and research on rural ethics issues. An interdisciplinary group of rural healthcare ethicists with backgrounds in medicine, nursing and philosophy was convened to explore the need for a rural healthcare ethics agenda. At the meeting, the Coalition for Rural Health Care Ethics agreed to a definition of rural healthcare ethics and a broad-ranging rural ethics agenda with the ultimate goal of enhancing the quality of patient care in rural America. The proposed agenda calls for increasing awareness and understanding of rural healthcare ethics through the development of evidence—informed, rural-attuned research, scholarship and education in collaboration with rural healthcare professionals, healthcare institutions and the diverse rural population.

Objective: To determine whether bioethicists are distributed along a rural-to-urban continuum in a way that reflects potential need of those resources as determined by the general population, hospital facilities and hospital beds.Methods: US members of a large, multidisciplinary professional society, the American Society of Bioethics and Humanities , the US population, hospital facilities and hospital beds were classified across a four-tier rural-to-urban continuum. The proportion of each group in rural settings was compared with that in urban settings, and odds ratios (...) were calculated with 95% confidence intervals.Results: Although 91% of ASBH members live or work in urban settings, only 66% of the US population did so. In contrast, 2% of ASBH members live or work in rural settings compared with 13% of the population. ASBH members were 10.7 times as likely to be represented in urban than in rural settings when compared with the general population, 25.6 times and 6.9 times as likely with regard to hospital facilities and hospital beds, respectively.Conclusions: Using various comparisons it was found that ASBH members are under-represented in rural as compared with urban settings. Although not all bioethicists are ASBH members, these findings suggest that the availability of professional bioethical resources may be inadequate in rural America. The disparities that were found may have considerable effect on ethics scholarship, research, ethical committees and education, and adds to the argument that rural American communities are under-served.

This book addresses identity-formation as it relates to social inclusivity. The stigmatized Other have long been marginalized in their social relations with the mainstream. This book reconstitutes the thinking which displaces social exclusiveness, replacing it with new ideas promoting social cohesiveness, reciprocity, and social inclusivity.

Somatic or inherited mutations in the adenomatous polyposis coli (APC) gene are a frequent cause of colorectal cancer in humans. APC protein has an important tumor suppression function to reduce cellular levels of the signaling protein β‐catenin and, thereby, inhibit β‐catenin and T‐cell‐factor‐mediated gene expression. In addition, APC protein binds to microtubules in vertebrate cells and localizes to actin‐rich adherens junctions in epithelial cells of the fruit fly Drosophila (Fig. 1). Very little is known, however, about the function of these (...) cytoskeletal associations. Recently, Hamada and Bienz have described a potential role for Drosophila E‐APC in cellular adhesion,1 which offers new clues to APC function in embryonic development, and potentially colorectal adenoma formation and tumor progression in humans.

We hypothesize that aspects of animal multicellularity originated before the divergence of metazoans from fungi and social amoebae. Polarized epithelial tissues are a defining feature of metazoans and contribute to the diversity of animal body plans. The recent finding of a polarized epithelium in the non‐metazoan social amoeba Dictyostelium discoideum demonstrates that epithelial tissue is not a unique feature of metazoans, and challenges the traditional paradigm that multicellularity evolved independently in social amoebae and metazoans. An alternative view, presented here, is (...) that the common ancestor of social amoebae, fungi, and animals spent a portion of its life cycle in a multicellular state and possessed molecular machinery necessary for forming an epithelial tissue. Some descendants of this ancestor retained multicellularity, while others reverted to unicellularity. This hypothesis makes testable predictions regarding tissue organization in close relatives of metazoans and provides a novel conceptual framework for studies of early animal evolution.Editor's suggested further reading in BioEssays Searching for Eve: Basal metazoans and the evolution of multicellular complexity Abstract.

Summary A provocative examination of the consequences of Levinas’s and Adorno’s thought for contemporary ethics and political philosophy. This book sets up a dialogue between Emmanuel Levinas and Theodor W. Adorno, using their thought to address contemporary environmental and social-political situations. Eric S. Nelson explores the “non-identity thinking” of Adorno and the “ethics of the Other” of Levinas with regard to three areas of concern: the ethical position of nature and “inhuman” material others such as environments and animals; the (...) bonds and tensions between ethics and religion and the formation of the self through the dynamic of violence and liberation expressed in religious discourses; and the problematic uses and limitations of liberal and republican discourses of equality, liberty, tolerance, and their presupposition of the private individual self and autonomous subject. Thinking with and beyond Levinas and Adorno, this work examines the possibility of an anarchic hospitality and solidarity between material others and sensuous embodied life. “This is an extremely impressive, original, and thorough treatment of two key twentieth-century thinkers and their applicability to the most pressing social and political issues of our time.” — Jeffrey A. Bernstein, author of Leo Strauss on the Borders of Judaism, Philosophy, and History “This book is an excellent and timely contribution to political and environmental philosophy, located around a nuanced historical and philosophical approach to Levinas and Adorno. It will be of great interest to anyone concerned with these figures or with the current moment.” — Martin Shuster, author of Autonomy after Auschwitz: Adorno, German Idealism, and Modernity.

Integrins are ubiquitous trans‐membrane adhesion molecules that mediate the interaction of cells with the extracellular matrix (ECM). Integrins link cells to the ECM by interacting with the cell cytoskeleton. In cases such as leukocyte binding, integrins mediate cell‐cell interactions and cell‐ECM interactions. Recent research indicates that integrins also function as signal transduction receptors, triggering a number of intracellular signaling pathways that regulate cell behavior and development. A number of integrins are known to stimulate changes in intracellular calcium levels, resulting in (...) integrin activation. Although changes in intracellular calcium regulate a vast number of cellular functions, this review will discuss the stimulation of calcium signaling by integrins and the role of intracellular calcium in the regulation of integrin‐mediated adhesion.

Beta‐catenin is a multifunctional protein with critical roles in cell‐cell adhesion, Wnt‐signaling and the centrosome cycle. Whereas the roles of β‐catenin in cell‐cell adhesion and Wnt‐signaling have been studied extensively, the mechanism(s) involving β‐catenin in centrosome functions are poorly understood. β‐Catenin localizes to centrosomes and promotes mitotic progression. NIMA‐related protein kinase 2 (Nek2), which stimulates centrosome separation, binds to and phosphorylates β‐catenin. β‐Catenin interacting proteins involved in Wnt signaling such as adenomatous polyposis coli, Axin, and GSK3β, are also localized at (...) centrosomes and play roles in promoting mitotic progression. Additionally, proteins associated with cell‐cell adhesion sites, such as dynein, regulate mitotic spindle positioning. These roles of proteins at the cell cortex and Wnt signaling that involve β‐catenin indicate a cross‐talk between different sub‐cellular sites in the cell at mitosis, and that different pools of β‐catenin may co‐ordinate centrosome functions and cell cycle progression.

The generation of asymmetric cell shapes is a recurring theme in biology. In budding yeast, one form of cell asymmetry occurs for division and is generated by anisotropic growth of the mother cell to form a daughter cell bud. Previous genetic studies uncovered key roles for the small GTPase Cdc42 in organizing the actin cytoskeleton and vesicle delivery to the site of bud growth,1,2 but a recent paper has also raised questions about how control of Cdc42 activity is integrated into (...) a proposed hierarchical regulatory pathway that specifies a unique site of bud formation.3 BioEssays 25:833–836, 2003. © 2003 Wiley Periodicals, Inc.
