Sovereign Debt, Austerity, and Regime Change The Case of Nicolae Ceausescu’s Romania
Historically, high sovereign debt and austerity policies have coincided with regime-changing popular uprisings. Nicolae Ceausescu’s Romania was no exception. Why, when faced with a sovereign debt crisis in the 1980s, did his regime choose to pay its foreign debt as early as possible, at the cost of economic recession and dramatically compressed consumption? How did these choices relate to the regime’s failure to survive the end of the decade?
Read moreEconomic transnationalism and its ambiguities: the case of Romanian migration to Italy
aking the case of migratory flows between Romania and Italy as a case study, this article investigates the ways in which spaces of economic transnationalism emerge and are reproduced over time. While the article finds that the role of the state in regulating the flow of money, people and goods across borders remains significant, it nevertheless provides evidence that state authority is systematically challenged by private actors even in the case
Read moreBrazil’s liberal neo-developmentalism: New paradigm or edited orthodoxy?
Is Brazil's economic policy regime a mere tinkering of the Washington Consensus? The evidence suggests that Brazilian governments institutionalized a hybrid policy regime that layers economically liberal priorities originating in the Washington Consensus and more interventionist ones associated with neo-developmentalist thinking. To capture this hybridity, the study calls this regime ‘liberal neo-developmentalism’. While defending the goal of

Aims. The aim of this study was to evaluate the leading causes of discrepancies between imaging studies [contrast enhanced ultrasound (CEUS) and contrast enhanced computer tomography (CECT)] diagnosis and histology in patients presenting to a tertiary referral center with previously detected pancreatic masses by standard abdominal ultrasound. Methods. We performed a prospective longitudinal observational study on 76 patients with pancreatic masses:
Read moreIntelligent decision-making for liver fibrosis stadialization based on tandem feature selection and evolutionary-driven neural network.
Hepatic fibrosis represents the principal pointer to the development of liver diseases. The correct evaluation of its degree, based on both recent non-invasive procedures and machine learning models, is of current major concern. One of the latest medical imaging methodologies for assessing it is the Fibroscan, supported by biochemical and clinical examinations. Since the complex interaction between the Fibroscan stiffness indicator and the biochemical

Pseudoaneurysm represents a rare complication in chronic pancreatitis, caused by enzymatic digestion of peripancreatic arteries or the erosion of a visceral artery by pseudocysts. The presence of multiple pseudoaneurysms is rarely seen and their association with splenic infarction has been rarely reported. This case presentation reports the concomitant presence of two pseudoaneurysms with different mechanisms of formation, one of them diagnosed by

High-frequency ultrasound is a noninvasive tool that offers characteristic markers, quantifying the cutaneous changes of the physiological senescence process. Aims: The aim was to assess the changes in skin thickness, dermal density and echogenicity, as part of the ageing process, with different age intervals. Methods : The study was performed on 160 patients, aged 40.4 ± 21.2, divided into four age categories:
Read moreThe role of i.v. and oral contrast enhanced ultrasonography in the characterization of gastric tumors. A preliminary study
To identify the diagnosis benefits of harmonics optimized i.v. contrast enhanced ultrasonography (CEUS) in the detection and characterization of several gastric neoplasms. Material and method: The study group included 10 patients with gastric neoplasms, either epithelial or stromal. The examination included grey scale ultrasonography combined with hydrosonography and harmonics ultrasonography with i.v. contrast media, centered on the tumor, using
