Application of Bayesian Techniques to Model the Burden of Human Salmonellosis Attributable to U.S. Food Commodities at the Point of Processing: Adaptation of a Danish Model
Mathematical models that estimate the proportion of foodborne illnesses attributable to food commodities at specific points in the food chain may be useful to risk managers and policy makers to formulate public health goals, prioritize interventions, and document the effectiveness of mitigations aimed at reducing illness. Using human surveillance data on laboratory-confirmed Salmonella infections from the Centers for Disease Control and Prevention and Salmonella testing data from U.S. Department of Agriculture Food Safety and Inspection Service's regulatory programs, we developed a point-of-processing foodborne illness attribution model by adapting the Hald Salmonella Bayesian source attribution model. Key model outputs include estimates of the relative proportions of domestically acquired sporadic human Salmonella infections resulting from contamination of raw meat, poultry, and egg products processed in the United States from 1998 through 2003. The current model estimates the relative contribution of chicken (48%), ground beef (28%), turkey (17%), egg products (6%), intact beef (1%), and pork (<1%) across 109 Salmonella serotypes found in food commodities at point of processing. While interpretation of the attribution estimates is constrained by data inputs, the adapted model shows promise and may serve as a basis for a common approach to attribution of human salmonellosis and food safety decision-making in more than one country
Survival following coronary angioplasty versus coronary artery bypass surgery in anatomic subsets in which coronary artery bypass surgery improves survival compared with medical therapy Results from the Bypass Angioplasty Revascularization Investigation (BARI)
AbstractOBJECTIVESWe sought to compare survival after coronary artery bypass graft (CABG) and percutaneous transluminal coronary angioplasty (PTCA) in high-risk anatomic subsets.BACKGROUNDCompared with medical therapy, CABG decreases mortality in patients with three-vessel disease and two-vessel disease involving the proximal left anterior descending artery (LAD), particularly if left ventricular (LV) dysfunction is present. How survival after PTCA and CABG compares in these high-risk anatomic subsets is unknown.METHODSIn the Bypass Angioplasty Revascularization Investigation (BARI), 1,829 patients with multivessel disease were randomized to an initial strategy of PTCA or CABG between 1988 and 1991. Stents and IIb/IIIa inhibitors were not utilized. Since patients in BARI with diabetes mellitus had greater survival with CABG, separate analyses of patients without diabetes were performed.RESULTSSeven-year survival among patients with three-vessel disease undergoing PTCA and CABG (n = 754) was 79% versus 84% (p = 0.06), respectively, and 85% versus 87% (p = 0.36) when only non-diabetics (n = 592) were analyzed. In patients with three-vessel disease and reduced LV function (ejection fraction <50%), seven-year survival was 70% versus 74% (p = 0.6) in all PTCA and CABG patients (n = 176), and 82% versus 73% (p = 0.29) among non-diabetic patients (n = 124). Seven-year survival was 87% versus 84% (p = 0.9) in all PTCA and CABG patients (including diabetics) with two-vessel disease involving the proximal LAD (n = 352), and 78% versus 71% (p = 0.7) in patients with two-vessel disease involving the proximal LAD with reduced LV function (n = 72).CONCLUSIONIn high–risk anatomic subsets in which survival is prolonged by CABG versus medical therapy, revascularization by PTCA and CABG yielded equivalent survival over seven years

Final Technical Report: Development of the DUSTRAN GIS-Based Complex Terrain Model for Atmospheric Dust Dispersion
Activities at U.S. Department of Defense (DoD) training and testing ranges can be sources of dust in local and regional airsheds governed by air-quality regulations. The U.S. Department of Energy’s Pacific Northwest National Laboratory just completed a multi-year project to develop a fully tested and documented atmospheric dispersion modeling system (DUST TRANsport or DUSTRAN) to assist the DoD in addressing particulate air-quality issues at military training and testing ranges

The U.S. Inland Creel and Angler Survey Catalog (CreelCat): Development, Applications, and Opportunities
Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular pastime in the USA. State natural resource agencies endeavor to provide high-quality and sustainable fishing opportunities for anglers. Managers often use creel and other angler survey data to inform state- and waterbody-level management efforts. Despite the broad implementation of angler surveys and their importance to fisheries management at state scales, regional and national coordination among these activities is minimal, limiting data applicability for larger-scale management practices and research. Here, we introduce the U.S. Inland Creel and Angler Survey Catalog (CreelCat), a first-of-its-kind, publicly available national database of angler survey data that establishes a baseline of national inland recreational fishing metrics. We highlight research and management applications to help support sustainable inland recreational fishing practices, consider cautions, and make recommendations for implementation
Colonial Archives and the Arts of Governance
Anthropologists engaged inpost-colonial studies are increasingly adoptingan historical perspective and using archives. Yet their archival activity tends to remain morean extractive than an ethnographic one.Documents are thus still invokedpiecemeal to confirm the colonial invention ofcertain practices or to underscore culturalclaims, silent. Yet such mining of the content of government commissions,reports, and other archival sources rarely paysattention to their peculiar placement and form .Scholars need to move fromarchive-as-source to archive-as-subject. Thisarticle, using document production in the DutchEast Indies as an illustration, argues thatscholars should view archives not as sites ofknowledge retrieval, but of knowledgeproduction, as monuments of states as well assites of state ethnography. This requires asustained engagement with archives as culturalagents of ``fact'' production, of taxonomies inthe making, and of state authority. What constitutes thearchive, what form it takes, and what systemsof classification and epistemology signal atspecific times are (and reflect) critical featuresof colonial politics and state power. The archive was the supreme technology of thelate nineteenth-century imperial state, arepository of codified beliefs that clustered(and bore witness to) connections betweensecrecy, the law, and power.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41825/1/10502_2004_Article_5096461.pd
Mujeres y cultura en la Argentina del siglo XIX
Este libro es el resultado de buscar y rebuscar, acuciadas en un primer momento por una natural curiosidad hacia el siglo XIX, en el baúl de nuestras abuelas o incluso bisabuelas. Y nos encontramos no sólo con el pasado sino con nuestro pasado, rico, complejo, sorprendente en su infinita variedad de hallazgos. Experimentamos un sentimiento de ternura por esas mujeres y de profunda solidaridad ante el esfuerzo que realizaron, muchas veces en condiciones inhóspitas, incomprendidas por sus contemporáneos, varones y mujeres. No sólo mujeres con nombre propio sino mujeres generalmente anónimas forman una parte esencial de la historia no contada, oculta(da) en el polvo acumulado durante el transcurso de los años. Nuestra tarea, nuestra pasión es desenvolverla, descubrirla, deconstruirla. Un acto compartido entre muchas mujeres y algunos varones. En mayor o menor grado, cada artículo en Mujeres y cultura en la Argentina del siglo XIXcontribuye a este fin y también al de la construcción –la re-construcción- de la historia de mujeres en la Argentina. Hay todavía mucho por revolver en esos arcones. Sabemos que hay nombres escondidos todavía en publicaciones que debemos encontrar. Nombres de mujeres, sus labores, que han sido muy poco investigadas o que sencillamente desconocemos. Se trata de hacer visible una producción ignorada y una tradición desdibujada
Com o diabo no corpo: os terríveis papagaios do Brasil colônia
Desde a Antiguidade, papagaios, periquitos e afins (Psittacidae) fascinaram os europeus por seu vivo colorido e uma notável capacidade de interação com seres humanos. A descoberta do Novo Mundo nada faria além de acrescentar novos elementos ao tráfico de animais exóticos há muito estabelecido pelos europeus com a África e o Oriente. Sem possuir grandes mamíferos, a América tropical participaria desse comércio com o que tinha de mais atrativo, essencialmente felinos, primatas e aves - em particular os papagaios, os quais eram embarcados em bom número. Contudo, a julgar pelos documentos do Brasil colônia, esses voláteis podiam inspirar muito pouca simpatia, pois nenhum outro animal - exceto as formigas - foi tantas vezes mencionado como praga para a agricultura. Além disso, alguns psitácidas mostravam-se tão loquazes que inspiravam a séria desconfiança de serem animais demoníacos ou possessos, pois só três classes de entidades - anjos, homens e demônios - possuíam o dom da palavra. Nos dias de hoje, vários representantes dos Psittacidae ainda constituem uma ameaça para a agricultura, enquanto os indivíduos muito faladores continuam despertando a suspeita de estarem possuídos pelo demônio. Transcendendo a mera curiosidade, essa crença exemplifica o quão intrincadas podem ser as relações do homem com o chamado “mundo natural”, revelando um universo mais amplo e multifacetado do que se poderia supor a princípio. Nesse sentido, a existência de aves capazes de falar torna essa relação ainda mais complexa e evidencia que as dificuldades de estabelecer o limite entre o animal e o humano se estendem além dos primatas e envolvem as mais inusitadas espécies zoológicas.Since ancient times, parrots and their allies (Psittacidae) have fascinated Europeans by their striking colors and notable ability to interact with human beings. The discovery of the New World added new species to the international exotic animal trade, which for many centuries had brought beasts to Europe from Africa and the Orient. Lacking large mammals, tropical America participated in this trade with its most appealing species, essentially felines, primates and birds - especially parrots - which were shipped in large numbers. It should be noted, however, that at times these birds were not well liked. In fact, according to documents from colonial Brazil, only the ants rank higher than parrots as the animals most often mentioned as agricultural pests. On the other hand, some of these birds were so chatty that people suspected them to be demonic or possessed animals, since only three classes of beings - angels, men and demons - have the ability to speak. Nowadays, several Psittacidae still constitute a threat to agriculture, and the suspicion that extremely talkative birds were demon possessed has also survived. More than a joke or a mere curiosity, this belief exemplifies how intricate man’s relationships with the “natural world” may be. In this sense, the existence of birds that are able to speak adds a further twist to these relationships, demonstrating that the problem of establishing a boundary between the animal and the human does not only involve primates, but also includes some unusual zoological species
