Avaliação de políticas públicas no Brasil e nos Estados Unidos : análise da pesquisa nos últimos 10 anos

Este estudo compara a pesquisa sobre avaliação de políticas públicas no Brasil e nos Estados Unidos. No intuito de examinar o grau em que a pesquisa em avaliação está estabelecida nesses países, este artigo usa os métodos bibliométrico e de análise de rede social para comparar as publicações recentes da pesquisa em avaliação em ambos os países. Os resultados mostram que o Brasil e os Estados Unidos têm pesquisado e publicado nas mesmas áreas, em especial, nas áreas de saúde, de educação e de bem-estar social. Observou-se também que os pesquisadores dos dois países utilizam métodos de investigação similares, embora os americanos façam maior uso de métodos quanti-quali e suas redes de pesquisa apresentem características semelhantes, apesar de as redes americanas serem de tamanho e densidade maiores. A partir das evidências encontradas, conclui-se que a pesquisa em avaliação no Brasil evoluiu durante o período investigado e que está em vias de consolidação como um campo de estudo e prática.This study compares research on evaluation of public policies in Brazil and the United States. To examine the extent to which evaluation research has been established in these countries, this article uses the methods of bibliometric and social network analysis to compare recent use of evaluation research in these countries.

Rapid evolution of A(H5N1) influenza viruses after intercontinental spread to North America

Highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b underwent an explosive geographic expansion in 2021 among wild birds and domestic poultry across Asia, Europe, and Africa. By the end of 2021, 2.3.4.4b viruses were detected in North America, signifying further intercontinental spread. Here we show that the western movement of clade 2.3.4.4b was quickly followed by reassortment with viruses circulating in wild birds in North America, resulting in the acquisition of different combinations of ribonucleoprotein genes. These reassortant A(H5N1) viruses are genotypically and phenotypically diverse, with many causing severe disease with dramatic neurologic involvement in mammals. The proclivity of the current A(H5N1) 2.3.4.4b virus lineage to reassort and target the central nervous system warrants concerted planning to combat the spread and evolution of the virus within the continent and to mitigate the impact of a potential influenza pandemic that could originate from similar A(H5N1) reassortants

Organizational Complexity in American Local Governance: Deploying an Organizational Perspective in Concept and Analytic Framework Development

Organizational complexity is a distinguishing characteristic of local governance in America\u27s urban areas. Organizationally complex arrangements among jurisdictions, agencies, and private for-profit and not-for-profit organizations are frequently involved in the production and delivery of local public goods and services in the United States. In this dissertation study the author seeks useful explanations regarding emergence, operation and consequences of organizational complexity found in local public economies in the United States. The study draws on the author\u27s professional practice and researcher experience and organizational theory to develop a conceptual platform for better understanding local public sector organizational complexity. The conceptual platform is operationalized through an analytic framework designed for study of hybrid organization in local governance. The study uses drug courts in a multi-site empirical test application of the analytic framework. Finally, the results of the study, conclusions drawn and implications for public administration and policy theory, research, education and practice are offered

Targeting Investments To Cost Effectively Restore and Protect Wetland Ecosystems: Some Economic Insights

USDA has spent more than $4.2 billion on wetland restoration and protection over the last two decades. One challenge in allocating these funds is the lack of information on variations in wetland benefits and costs across the Nation. This report discusses the biophysical impacts of new wetlands for eight benefit categories: duck hunting, carbon sequestration, flood protection, nitrogen removal, species protection, open space, sediment removal, and groundwater recharge, as well as the value of these impacts for some categories. In addition, it presents county-level estimates of the costs of restoring and preserving wetlands for some parts of the United States. Although the estimates range in precision and are not comprehensive, they call attention to some areas where the benefits of new wetlands are likely to exceed costs or perhaps may be insignificant. For example, the benefits of restoring and preserving wetlands near the Missouri River in central North and South Dakota are likely to exceed costs. Findings underscore the need for additional information that may increase the number, accuracy, and spatial resolution of wetland benefit estimates

Rapid evolution of A(H5N1) influenza viruses after intercontinental spread to North America

Abstract Highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b underwent an explosive geographic expansion in 2021 among wild birds and domestic poultry across Asia, Europe, and Africa. By the end of 2021, 2.3.4.4b viruses were detected in North America, signifying further intercontinental spread. Here we show that the western movement of clade 2.3.4.4b was quickly followed by reassortment with viruses circulating in wild birds in North America, resulting in the acquisition of different combinations of ribonucleoprotein genes. These reassortant A(H5N1) viruses are genotypically and phenotypically diverse, with many causing severe disease with dramatic neurologic involvement in mammals. The proclivity of the current A(H5N1) 2.3.4.4b virus lineage to reassort and target the central nervous system warrants concerted planning to combat the spread and evolution of the virus within the continent and to mitigate the impact of a potential influenza pandemic that could originate from similar A(H5N1) reassortants

Assessing the fitness of distinct clades of influenza A (H9N2) viruses

Influenza A (H9N2) viruses are a genetically diverse population that infects wild and domestic avian species and mammals and contributed the internal gene segments to the A/H5N1 and A/H7N9 viruses associated with lethal human infections. Here we comprehensively assess the potential risk to mammals of a diverse panel of A/H9N2 viruses, representing the major H9N2 clades, using a combination of in vitro assays (e.g., antiviral susceptibility and virus growth in primary differentiated human airway cells) and in vivo assays (e. g., replication, transmission and/or pathogenicity of viruses in ducks, pigs, mice and ferrets). We observed that viruses isolated from humans, A/Hong Kong/1073/1999 and A/Hong Kong/33982/2009, had the highest risk potential. However, the A/swine/Hong Kong/9A-1/1998 and A/chicken/Hong Kong/G9/1997 viruses also displayed several features suggesting a fitness profile adapted to human infection and transmission. The North American avian H9N2 clade virus had the lowest risk profile, and the other viruses tested displayed various levels of fitness across individual assays. In many cases, the known genotypic polymorphisms alone were not sufficient to accurately predict the virus' phenotype. Therefore, we conclude that comprehensive risk analyses based on surveillance of circulating influenza virus strains are necessary to assess the potential for human infection by emerging influenza A viruses
