Resumo: A ascensão de lideranças autoritárias de extrema direita nas democracias contemporâneas catalisou processos de retrocesso democrático com profundas e diversas implicações políticas. Uma das dimensões menos exploradas desse fenômeno é o impacto das ações desses líderes políticos no funcionamento das burocracias públicas. Nesse sentido, a questão que orienta nossa análise é: como se dá a dinâmica entre controle político e reações burocráticas em contextos de retrocesso democrático? A análise se baseia em 165 entrevistas com burocratas de médio escalão entre dezembro de 2020 e julho de 2021 em 15 organizações diferentes das áreas social, econômica, ambiental e de planejamento do governo federal brasileiro durante o governo Bolsonaro. Os achados sugerem que o controle político e a reação burocrática estabelecem uma dinâmica que envolve interações e um processo de aprendizagem ao longo do tempo. Abstract: The rise of far-right authoritarian leaders in contemporary democracies has catalyzed processes of democratic backsliding, with profound and diverse political implications. One of the least explored dimensions of this phenomenon is the impact of the actions of these political leaders on the functioning of government bureaucracies. The question that guides our analysis is: how does the dynamic between political control and bureaucratic reaction take place in contexts of democratic backsliding? The analysis is based on 165 interviews with mid-level bureaucrats between December 2020 and July 2021 in 15 different social, economic, environmental and planning organizations of the Brazilian federal government during the Bolsonaro government. The findings suggest that political control and bureaucratic reaction is a dynamic relationship that involves interactions and learning over time.

The measurement of conducted emissions in the 2 kHz to 150 kHz frequency range, also referred to as High Frequency (HF) Emissions (HFEs) or Supraharmonics, is gaining more and more importance. This is due to highly increasing switching frequency of power converters. In low voltage power systems, Light Emitting Diode (LED) lamps are a widespread diffused loads with switching frequency up to some tens of kilohertz. HFEs from LED lamps are in the same frequency range of Power Line Communications (PLCs), widely used for vital grid operations as protection or meter reading. This paper presents the results of a preliminary experimental study focused on the evaluation of the effects of HFEs from LED lamps on the reliability of PLCs.

The large and diverse availability of mobility data enables the development of predictive models capable of recognizing various types of movements. Through a variety of GPS devices, any moving entity, animal, person, or vehicle can generate spatio-temporal trajectories. This data is used to infer migration patterns, manage traffic in large cities, and monitor the spread and impact of diseases, all critical situations that necessitate a thorough understanding of the underlying problem. Researchers, businesses, and governments use mobility data to make decisions that affect people's lives in many ways, employing accurate but opaque deep learning models that are difficult to interpret from a human standpoint. To address these limitations, we propose Geolet, a human-interpretable machine-learning model for trajectory classification. We use discriminative sub-trajectories extracted from mobility data to turn trajectories into a simplified representation that can be used as input by any machine learning classifier. We test our approach against state-of-the-art competitors on real-world datasets. Geolet outperforms black-box models in terms of accuracy while being orders of magnitude faster than its interpretable competitors.

Resumo O texto retrata as disputas interpretativas em torno da “natureza jurídica” das medidas protetivas de urgência da Lei Maria da Penha, que se dão na doutrina e nos tribunais. Ao privilegiar o ponto de vista das mulheres na interpretação do direito, chama a atenção para o fato de que uma disputa interpretativa aparentemente anódina de taxonomia conceitual esconde consequências cruciais para a vida e segurança das mulheres. Por meio de entrevistas com atrizes do sistema de justiça e da rede de atendimento às mulheres vítimas de violência, mostra como as interpretações que veem as medidas protetivas como acessórias ao processo impõem ônus injustificado às mulheres para que tenham acesso a um direito conquistado. Além de deixá-las desprotegidas, submetem-nas a procedimentos revitimizadores, limitam as suas alternativas de apoio e suprimem seu espaço de escolha. Abstract This article portraits the interpretative (doctrinal and judicial) disputes concerning the “legal nature” of urgent protective measures, which are prescribed by the Maria da Penha Statute. By giving privilege to the women's point of view regarding the interpretation of law, this work draws attention to the fact that an interpretative dispute about conceptual taxonomy, although seemingly anodyne, hides crucial consequences to women's lives and safety. We utilized interviews with actresses from the justice system and from assistance network to victims of violence to demonstrate how the interpretation which considers the urgent protective measures accessories to the judicial procedure imposes on women an unjustified burden to a conquered legal right. Besides leaving them unprotected, such interpretation submits women to revictimizing procedures, limits the alternatives of support to the victims and suppresses their choices.

The liberalization of the railway market and the aim of fostering the interoperability among European countries makes the monitoring of the quality of the power (PQ) exchanged between trains and supply system even more important. At the moment, definitions, procedures and techniques for DC railway systems are under development. In this contest, the paper proposes a reference generation system able to reproduce the voltage and current waveforms experienced at pantograph by a DC 3 kV locomotive. The system is able to generate simultaneously voltage and current signals up to 10 kV peak and 1.2 kA peak respectively. The AC ripple which can be superimposed has a bandwidth of 30 kHz for the voltage and 600 Hz for the current. Moreover, it is able to reproduce several PQ events both with an accuracy, in the worst case of 1%.

All the measurement tasks, f.i. metering, protection and diagnostics, in electricity distribution and trasmission grids need instrument transformers (ITs) to scale voltage and current down to levels compatible with measuring instruments. Inductive voltage and current transformers (VTs and CTs) are still the most used ITs; however, their behaviour in presence of disturbances is not fully assessed. This paper analyses the behavior of CTs in presence of amplitude modulations, which is one of the disturbance under which the performance of Phasor Measurement Units (PMUs) has to be assessed. A measurement setup, able to test current transformers in accordance to the IEEE Std. C37.118.1 about the PMU performance testing, has been realized. Experimental tests on a commercial CT, changing the modulation frequency, are presented., The work reported here has received support from the EMPIR programme co-financed by the Participating States and from the European Union's

Acute exacerbations (AEs) are among the main causes of death in idiopathic pulmonary fibrosis (IPF) patients. In this study proteomic comparative analysis of bronchoalveolar lavage (BAL) fluid samples was performed in stable IPF patients versus AEs IPF group to identify AE pathogenetic mechanisms and novel potential predictive biomarkers. A functional proteomic analysis of BAL fluid samples from stable and AE-IPF patients was conducted in a population of 27 IPF patients. Fifty-one differentially abundant spots were observed and identified by mass spectrometry. Enrichment analysis found proteins of interest involved in the regulation of macrophages and lipid metabolism receptors. In acute exacerbation IPF group, differentially abundant proteins were involved in propagation of the v-catenin WNT transduction signal, and proteins up-regulated in lung carcinogenesis (IGKC, S100A9, PEDF, IGHG1, ALDOA, A1AT, HPT, CO3 and PIGR) and acute phase proteins involved in protease-antiprotease imbalance (such as A1AT fragments). Dot-blot analysis of A1AT C-36 peptide allowed validating our findings, confirming up-regulation in AE IPF patients and suggesting its potential pathogenetic role. A crucial role of protease/antiprotease imbalance, clathrin-mediated endocytosis signalling and carcinogenesis emerged in IPF patients developing acute exacerbations.

In the new electrical system scenario, the increasing presence of non-linear loads and renewable energy sources makes the measurement of harmonics an essential task. The accuracy of harmonic measurement firstly depends on the used instrument transformers for voltage and current sensing. Since the behavior of instrument transformers in non-sinusoidal conditions is not always well defined, this paper presents an experimental study on the metrological performances of current and voltage instrument transformers (CTs and VTs) in the presence of harmonics. Proper tests procedures are defined and measurement setups are developed for both CTs and VTs calibration. The analysis is carried out by using test waveforms composed of a fundamental and one harmonic component. The harmonic ratio and phase errors are evaluated; the distortion effects on the errors on the fundamental component measurement are also investigated. The obtained results show how the metrological performances in harmonics measurement are influenced by both amplitude and phase shift of the harmonics.
