Determining Satisfaction with Access and Financial Aspects of Care for Persons Exposed to Libby Amphibole Asbestos: Rural and National Environmental Policy Implications

Libby, Montana is a Superfund site and epicenter of one of the worst environmental disasters in the USA history in terms of asbestos-related mortality and morbidity. Perceptions of access and financial aspects of care were explored among a national cohort of persons postasbestos exposure and prior to a 2009 Public Health Emergency Declaration. Our findings indicated the Libby cohort was significantly less satisfied with access and financial aspects of care as measured by two PSQ-III scales when compared to an adult, chronically ill patient sample. Participants with higher levels of respiratory morbidity and depression had significantly lower satisfaction scores

The Transformation of Social Institutions in the North American Southeast

Corporate institutions, which transformed in the American Southeast over some 14,000 years, include social heterarchies and hierarchies that arose within the institutional contexts of descent groups, ritual sodalities, and social houses. The strategic and tactical actions of competitive and cooperative agents contributed to differing expressions of organizational changes through a variety of forms, including feasting, feuding/warfare, inalienable goods circulation, indebtedness, monumental constructions, mortuary events, processions/rogations, strategic marriages, and additional ritual and social practices. The nexus of social institutions that evolved along these pathways served as a catalyst for social changes, including the ways through which social institutions became transformed. Such social processes inform archaeologists of the agency, organization, and practice of people who not only invented and manipulated cosmologies, ideologies, institutions, and resources to achieve varying degrees of inequality, power, and wealth, but also those who resisted the efforts of aggrandizers. The author’s arguments focus on aristocratic social actions and actors, and the practices that enabled them to gain power and wealth through exclusive and restrictive corporate institutions

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu
