"Donald Trump is my President!" The Internet Research Agency Propaganda Machine

This article presents a typological study of the Twitter accounts operated by the Internet Research Agency (IRA), a company specialized in online influence operations based in St. Petersburg, Russia. Drawing on concepts from 20th century propaganda theory, we modeled the IRA operations along propaganda classes and campaign targets. The study relies on two historical databases and data from the Internet Archive’s Wayback Machine to retrieve 826 user profiles and 6377 tweets posted by the agency between 2012 and 2017. We manually coded the source as identifiable, obfuscated, or impersonated and classified the campaign target of IRA operations using an inductive typology based on profile descriptions, images, location, language, and tweeted content. The qualitative variables were analyzed as relative frequencies to test the extent to which the IRA’s black, grey, and white propaganda are deployed with clearly-defined targets for short, medium, and long-term propaganda strategies. The results show that source classification from propaganda theory remains a valid framework to understand IRA’s propaganda machine and that the agency operates a composite of different user accounts tailored to perform specific tasks, including openly pro-Russian profiles, local American and German news sources, pro-Trump conservatives, and black lives matter activists

Robustness and the Paradox of Bridging Organizations: The Exit Problem in Regional Water Governance Networks in Central America

Bridging organizations facilitate a range of governance processes, including cooperation and social learning, and are theorized to be a key component of robust governance systems. In this article, we use node removal simulations to test structural hypotheses of robustness in a regional water governance network in Central America. We investigate the response of network measures supporting core governance processes to the targeted removal of bridging organizations and other actors, which we compare to random and centrality-based simulations. The results indicate removing bridging organizations has a greater impact on the network than any other type of actor, suggesting bridging organizations are critical to the robustness of the governance system. Furthermore, network structures supporting cooperation may be less robust than structures facilitating social learning. We conclude with policy implications of the research findings as they relate to the exit problem in governance systems with a large presence of international development actors

Produção de mudas de goiabeira.

A goiaba ocupa lugar de destaque dentre as frutas tropicais brasileiras. No Vale do São Francisco, a área plantada com a cultura é de 5.000 hectares, distribuídos entre os estados de Pernambuco e Bahia. A goiaba é uma ótima opção para a diversificação, entretanto, com os problemas surgidos por causa do nematoide, muitos pomares foram erradicados. Visando contribuir para a redução desses problemas, deve-se dar importância especial à produção de mudas livres de nematoides, pois, é no preparo delas que grande parte das áreas são contaminadas por essa praga. A produção de mudas é uma das etapas fundamentais no processo de implantação de um pomar e pode ser determinante para o sucesso da cultura a ser implantada. As técnicas de produção devem atender às necessidades do produtor, levando-se em consideração a disponibilidade e a localização de áreas, o grau de tecnologia e os recursos financeiros disponíveis.bitstream/item/54791/1/COT148.pd

Diabetic nephropathy: glomerular filtration rate and estimated creatinine clearance

OBJECTIVE: To assess in diabetic nephropathy, the accuracy of estimated creatinine clearance (calculated with the Cockroft Gault formula) and the clearance of the Tc99m-DTPA, to measure the glomerular filtration rate (GFR). PATIENTS AND METHODS: We analysed the GFR measure by Tc99m-DTPA method and the estimated by the Cockroft Gault formula, in 21 subjects with type 1 or type 2 diabetes. RESULTS: There was a strong positive correlation between the two methods but the Cockroft Gault formula underestimated the GFR. CONCLUSIONS: The formula gives a accurate estimates of GFR, when GFR is <100 ml/min/1,73 m2. Beside the underestimation, the formula could be used in the management of diabetic nephropathy because the repeated isotope assessments of renal function are impracticable
