This article examines changes in employed African American mothers' use of relatives for child care. Data from nationally representative pooled cross sections show that the proportion of Black mothers relying on extended kin for care of their preschool-age children declined significantly between 1977 and 1994. Multivariate analyses reveal that the decline characterized all subgroups of employed African American mothers but was less pronounced for young, single, mothers living outside the South. Thus, by 1994, employed Black mothers who most needed relatives' (...) child care support received it, while those who could manage without such help did so. This change suggests that African Americans' use of kin-provided support responds to shifts in broader social and economic conditions that affect the balance of resources and needs within extended families.

The co-occurrence of stress-induced posttraumatic stress disorder and obesity is common, particularly among military personnel but the link between these conditions is unclear. Individuals with comorbid PTSD and obesity manifest other physical and psychological problems, which significantly diminish their quality of life. Current understanding of the pathways connecting stress to PTSD and obesity is focused largely on behavioral mediators alone with little consideration of the biological regulatory mechanisms that underlie their co-occurrence. In this work, we leverage prior knowledge to systematically (...) highlight such bio-behavioral mechanisms and inform on the design of confirmatory pilot studies. We use natural language processing to extract documented regulatory interactions involved in the metabolic response to stress and its impact on obesity and PTSD from over 8 million peer-reviewed papers. The resulting network describes the propagation of stress to PTSD and obesity through 34 metabolic mediators using 302 documented regulatory interactions supported by over 10,000 citations. Stress jointly affected both conditions through 21 distinct pathways involving only two intermediate metabolic mediators out of a total of 76 available paths through this network. Moreover, oxytocin, Neuropeptide-Y, and cortisol supported an almost direct propagation of stress to PTSD and obesity with different net effects. Although stress upregulated both NPY and cortisol, the downstream effects of both markers are reported to relieve PTSD severity but exacerbate obesity. The stress-mediated release of oxytocin, however, was found to concurrently downregulate the severity of both conditions. These findings highlight how a network-informed approach that leverages prior knowledge might be used effectively in identifying key mediators like OXT though experimental verification of signal transmission dynamics through each path will be needed to determine the actual likelihood and extent of each marker’s participation.

Background: One of the barriers to interprofessional ethics education is a lack of resources that actively engage students in reflection on living an ethical professional life. This project implemented and evaluated an innovative resource for interprofessional ethics education. Objectives: The objective of this project was to create and evaluate an interprofessional learning activity on professionalism, clinical ethics, and research ethics. Design: The Brewsters is a choose-your-own-adventure novel that addresses professionalism, clinical ethics, and research ethics. For the pilot of the book, (...) a pre-test/post-test design was used. Once implemented across campus, a post-test was used to evaluate student learning in addition to a student satisfaction survey. Participants and research context: A total of 755 students in six academic schools in a health science center completed the activity as part of orientation or in coursework. Ethical considerations: The project was approved as exempt by the university’s Committee for the Protection of Human Subjects. Findings: The pilot study with 112 students demonstrated a significant increase in student knowledge. The 755 students who participated in the project had relatively high knowledge scores on the post-test and evaluated the activity positively. Discussion: Students who read The Brewsters scored well on the post-test and had the highest scores on clinical ethics. Clinical ethics scores may indicate issues encountered in mass media. Conclusion: The Brewsters is an innovative resource for teaching interprofessional ethics and professionalism. Further work is needed to determine whether actual and long-term behavior is affected by the activity. (shrink)

This article looks at the ways in which Spanish American women exploited the political and social turmoil of the late 18th and early 19th centuries to move beyond their traditional sphere of influence in the home. Women directly participated in the Túpac Amaru Rebellion (1780–1781) and in the Wars of Independence (1810–1825) providing funding, food supplies, infrastructure and reinforcements for the troops, and nursing the wounded. Others contributed by taking part in the physical fighting (both openly and disguised as men) (...) and a few led troops into battle. This article looks at some of the individuals behind the statistics and reveals their determination to participate despite the punishments imposed on women found guilty of disloyalty to the Spanish crown. Spanish colonial law had to be amended to ensure that women dissidents were given as equally harsh sentences as men. In the immediate post-independence period, rather than be seen as misfits or a threat to the patriarchal system, several of these women were given national awards. (shrink)

In this article I take a poem by Lisa Bellear as a starting point for theorizing the possibility of a renovated feminism. I argue that the rhetorical questioning of the poem performs a mode of intersubjectivity in which the addressee/reader reflects upon their whiteness. The poem drives directly into the dense affect that saturates the troubled zone of cross-racial relations in contemporary Australia. If this zone is characterized by white anger and anxiety, it is also a zone of intense `feeling' (...) for the indigenous poet. Jean-Luc Nancy defines literature as the act of the `opening [of] community to itself', that is, of communicating our being-in-common. The cross-racial encounter that Bellear brokers between an indigenous and a white woman through the performance of address in this poem is not entirely comfortable or governable. I discuss how my students find this poem so confronting, and the fact that this discomfort underlines the necessity for a pedagogy that accommodates what Spivak refers to as `moments of bafflement'.

Competence is an active state that defines the way in which cells respond to an inductive signal. A challenge of developmental biology is to explain not just the nature of the signalling molecules that promote cell specification or differentiation, but also how cells acquire competence to respond to these signals and what that reflects in molecular terms. A recent paper by Carmena et al.(1) has revealed how several signalling mechanisms are used sequentially and in specific combinations to specify two mesodermal (...) lineages in Drosophila.

A new high‐resolution structure of a pain‐sensing ion channel, TRPA1, provides a molecular scaffold to understand channel function. Unexpected structural features include a TRP‐domain helix similar to TRPV1, a novel ligand‐binding site, and an unusual C‐terminal coiled coil stabilized by inositol hexakisphosphate (IP6). TRP‐domain helices, which structurally act as a nexus for communication between the channel gates and its other domains, may thus be a feature conserved across the entire TRP family and, possibly, other allosterically‐gated channels. Similarly, the TRPA1 antagonist‐binding (...) site could also represent a druggable location in other ion channels. Combined with known TRPA1 functional properties, the structural role for IP6 leads us to propose that polyphosphate unbinding could act as a molecular kill switch for TRPA1 inactivation. Finally, although packing of the TRPA1 membrane‐proximal region hints at a mechanism for electrophile sensing, the details of how TRPA1 responds to noxious reactive electrophiles and temperature await future studies.Also watch the Video Abstract.

An interdisciplinary theoretical framework is proposed for analysing justice in global working conditions. In addition to gender and race as popular criteria to identify disadvantaged groups in organizations, in multinational corporations (MNCs) local employees (i.e. host country nationals (HCNs) working in foreign subsidiaries) deserve special attention. Their working conditions are often substantially worse than those of expatriates (i.e. parent country nationals temporarily assigned to a foreign subsidiary). Although a number of reasons have been put forward to justify such inequalities—usually with (...) efficiency goals in mind—recent studies have used equity theory to question the extent to which they are perceived as fair by HCNs. However, since perceptual equity theory has limitations, this study develops an alternative and non-perceptual framework for analysing such inequalities. Employment discrimination theory and elements of Rawls’s ‘Theory of Justice’ are the theoretical pillars of this framework. This article discusses the advantages of this approach for MNCs and identifies some expatriation practices that are fair according to our non-perceptual justice standards, whilst also reasonably (if not highly) efficient.

It is important to talk about corporations as a class, about trade agreements, and about government policy; but without examining specific examples of how real corporations actually shape the world to suit their purposes, we stand little chance of understanding the determinative forces behind government policy and trade agreements, and even less chance of affecting them. This article uses the metaphor of “genetics” (inherent character) to examine two major transnational corporations operating at the extremes of restructuring life.

This text asks what it is to be human. Spectres, cyborgs, clones, aliens - contemporary representations of the inhuman hybrid seem more various, multiform and pressing than ever before. Increasingly the blurred distinction between human and inhuman and the attendant technisation of social life raises a series of opportunities for cultural analysis: both in terms of its current transformative refiguration of body and self and in relation to the narratives, networks and communities within which these new identities are redeployed and (...) enjoyed. In the process of mapping a cultural genealogy which stretches from romanticism to "Neuromancer", this volume examines the impact of science and technology on culture and representation - past, present and future - and resituates the inhuman as a significant contemporary conceptual motif as it resonates across and within the philosophical trajectory of modernity.
