As reações ameríndias à conquista, segundo Florestan Fernandes
Authors: Amparo Sandoval Dos Santos 
Published: May 2022

O objetivo deste texto é apresentar três tipos de reações ameríndias ao processo de conquista territorial no Brasil, com base em Florestan Fernandes, Ruy Moreira e Rogério Haesbaert. Assim, na primeira parte discorrosobre o processo de disponibilização territorial, para em seguida, apresentar os processos de a) preservação da autonomia, submissão e reterritorialização. A importância da compreensão histórico-geográfica destas três formas de reação decorre do fato de que todas elas se mostram contemporâneas dos dias atuais, estando presente nas formas de reação de um ou outro grupo/nação indígena em relação ao avanço do processo de de territorialização.
Estado capitalista versus campesinato: reflexões sobre a questão agrária na região do Cariri Cearense
Authors: Piancó Ana Roberta Duarte , Nobre Francisco Wlirian 
Published: May 2022

O Presente artigo objetiva discutir as relações contraditórias entre o Estado capitalista e o campesinato caririense. Tomamos como ponto de partida o período colonial para contextualizar historicamente, as principais ações do Estado em diferentes momentos de invasões, apropriações e lutas pela propriedade das terras entre as populações locais, como índios e camponeses contra invasores portugueses e aqueles oriundos de outros estados do Nordeste. Realizamos a pesquisa com o aporte teórico dos autores Brito (2016), Fernandes (2001), Jonh Locke (2002), Martins (1995) e Oliveira (2007), utilizando como técnica de coleta de dados estudo bibliográfico, documental e pesquisa de campo. É fato que os camponeses foram aos poucos sendo esmagados pelo poder do Estado devido à dificuldade de unificação de suas pautas, contudo, é indiscutível a resiliência do campesinato na questão agrária brasileira, conforme veremos nas lutas e resistências, passadas e atuais dos camponeses caririenses.
Agroecologia e organizações sociais: os desafios da convivência com o semiárido no sertão de Pernambuco
Authors: Rapozo Bruna Maria da Silva 
Published: May 2022

Agroecologia é um campo de conhecimento em disputa, havendo assim correntes de pensamentos distintas e falta de consenso na definição do conceito, mas não se pode negar que o conhecimento e as práticas agroecológicas sempre estiveram presentes no modo de produzir e viver dos agricultores e agricultoras camponesas do sertão Semiárido. Por meio de saberes e conhecimentos oriundos da cultura tradicional de seus antepassados, os camponeses e as camponesas, em parceria com alguns agentes e atores sociais estão construindo estratégias para conviver com as condições naturais do Semiárido nordestino. Os conhecimentos agroecológicos sobre as formas de cultivar, cuidar da terra, das águas e das sementes, assim como as técnicas de captação e armazenamento das águas da chuva foram apreendidos a partir da leitura da natureza e experimentação que levaram a construção das estratégias para viver melhor e com condições de produção de alimentos de forma diversificada nos territórios e comunidades rurais. Mediante o exposto, esse artigo foi construído com base nos resultados da pesquisa de Mestrado em Geografia realizado pela autora do trabalho.

Published: May 2022

El objetivo del trabajo fue determinar la planificación del ecoturismo en la comunidad campesina de Huancaya. Se realizó el diagnostico Físico, Socioeconómico, Cultural y ubicación de los recursos ecoturísticos por coordenadas geográficas y su altitud. Se utilizo el método deductivo, descriptivo y de análisis – síntesis, así como el método de observación, en tres salidas de campo utilizando planos básicos, GPS, hojas de ruta. Los resultados obtenidos nos permitió elaborar cualitativamente un listado de lugares de interés turístico de la comunidad campesina de Huancaya acorde con los lineamientos del Plan estratégico Nacional de turismo sostenible, ya que la zona posee recursos y atractivos eco turísticos como sitios naturales, manifestaciones culturales que motivan corrientes turísticas nacionales e internacionales desarrollando en el futuro una oferta ecoturística nacional competitiva y sostenible, manteniendo inalterable la biodiversidad y las manifestaciones culturales del área trabajada. El ecoturismo en el distrito de Huancaya se presenta como un una alternativa de desarrollo pues cuenta con recursos turísticos excepcionales para su manejo y planificación; la limitación es la falta de preocupación de los pobladores sobre los atractivos turísticos, mejoramiento de la infraestructura vial para el traslado de visitantes y de los servicios que tienen una baja calidad tanto en la presentación y prestación, el cual se verá superada con la capacitación permanente, la planificación y puesta en valor de los recursos de la comunidad de Huancaya.
A nova ordem conservadora e o desmonte das políticas públicas de promoção da igualdade racial e combate ao racismo no Brasil
Authors: Muniz Aristóteles Veloso da Silva 
Published: May 2022

No Brasil, a eleição para presidente de Jair Messias Bolsonaro representou, em detrimento dos avanços democráticos dos anos anteriores, o surgimento de uma nova ordem contra-hegemônica cujos objetivos políticos alimentam uma agenda de desmonte, de desqualificação e de deslegitimação das pautas das minorias buscando conter os avanços democráticos até então postos. Este trabalho tem como objetivo afirmar que, entre 2014 e 2019, no Brasil, se identifica a consolidação de uma conjuntura contaminada por processos políticos apresentados a nível internacional que estão a corroer as estruturas democráticas, a atacar os direitos das minorias e a negar a possibilidade de avanços das políticas de direitos humanos, tudo isso em favor de uma agenda econômica que busca garantir os interesses e a reprodução social e política do grande capital financeiro e do seu campo ideológico e político. Nossa afirmação se baseia em uma revisão da literatura sobre a crise democrática e o avanço de uma onda conservadora a nível local; e na observação e no acompanhamento dos fatos e processos políticos, ligados à agenda do combate ao racismo e na promoção da igualdade racial, que buscaram deslegitimar e desmontar a Secretaria de Políticas de Promoção da Igualdade Racial (Seppir), negando e impedindo o reconhecimento e regulamentação das comunidades quilombolas e incentivando ou negligenciando ataques às religiões de matriz africana e afro-brasileira.

Very low frequency IEPE accelerometer calibration and application to a wind energy structure
Authors: Jonscher Clemens , Hofmeister Benedikt , Grießmann Tanja , Rolfes Raimund 
Published: May 2022

Abstract. In this work, we present an experimental setup for very low frequency calibration measurements of low-noise integrated electronics piezoelectric (IEPE) accelerometers and a customised signal conditioner design for using IEPE sensors down to 0.05 Hz. AC-response IEPE accelerometers and signal conditioners have amplitude and phase deviations at low frequencies. As the standard calibration procedure in the low-frequency range is technically challenging, IEPE accelerometers with standard signal conditioners are usually used in frequency ranges above 1 Hz. Vibrations on structures with low eigenfrequencies like wind turbines are thus often monitored using DC-coupled micro-electro-mechanical system (MEMS) capacitive accelerometers. This sensor type suffers from higher noise levels compared to IEPE sensors. To apply IEPE sensors instead of MEMS sensors, in this work the calibration of the entire measurement chain of three different IEPE sensors with the customised signal conditioner is performed with a low-frequency centrifuge. The IEPE sensors are modelled using infinite impulse response (IIR) filters to apply the calibration to time-domain measurement data of a wind turbine support structure. This procedure enables an amplitude and phase-accurate vibration analysis with IEPE sensors in the low-frequency range down to 0.05 Hz.
Large-eddy simulation of airborne wind energy farms
Authors: Haas Thomas , De Schutter Jochem , Diehl Moritz , Meyers Johan 
Published: May 2022

Abstract. The future utility-scale deployment of airborne wind energy technologies requires the development of large-scale multi-megawatt systems. This study aims at quantifying the interaction between the atmospheric boundary layer (ABL) and large-scale airborne wind energy systems operating in a farm. To that end, we present a virtual flight simulator combining large-eddy simulations to simulate turbulent flow conditions and optimal control techniques for flight path generation and tracking. The two-way coupling between flow and system dynamics is achieved by implementing an actuator sector method that we pair to a model predictive controller. In this study, we consider ground-based power generation pumping-mode AWE systems (lift-mode AWES) and on-board power generation AWE systems (drag-mode AWES). The aircraft have wingspans of approximately 60 m and fly large loops of approximately 200 m diameter centred at 200 m altitude. For the lift-mode AWES, we additionally investigate different reel-out strategies to reduce the interaction between the tethered wing and its own wake. Further, we investigate AWE parks consisting of 25 systems organised in five rows of five systems. For both lift- and drag-mode archetypes, we consider a moderate park layout with a power density of 10 MW km−2 achieved at a rated wind speed of 12 m s−1. For the drag-mode AWES, an additional park with denser layout and power density of 28 MW km−2 is also considered. The model predictive controller achieves very satisfactory flight path tracking despite the AWE systems operating in fully waked, turbulent flow conditions. Furthermore, we observe significant wake effects for the utility-scale AWE systems considered in the study. Wake-induced performance losses increase gradually through the downstream rows of systems and reach up to 17 % in the last row of the lift-mode AWE park and up to 25 % and 45 % in the last rows of the moderate and dense-drag-mode AWE parks respectively. For an operation period of 60 min at a below-rated reference wind speed of 10 m s−1, the lift-mode AWE park generates about 84.4 MW of power, corresponding to 82.5 % of the power yield expected when AWE systems operate ideally and interaction with the ABL is negligible. For the drag-mode AWE parks, the moderate and dense layouts generate about 86.0 and 72.9 MW of power respectively corresponding to 89.2 % and 75.6 % of the ideal power yield.
Il sogno di Chopin nell’autobiografia di George Sand
Authors: Palandrani Tiziana 
Published: May 2022

Nel presente lavoro viene analizzato il sogno di Chopin raccontato da George Sand nell'ultimo volume di Histoire de ma vie, dal punto di vista della produzione letteraria dello scrittore, e includendo il contesto artistico-letterario del tempo in cui furono modificato i loro ricordi. Nell'analisi generale della sua opera di lei suscita una ricorrenza di motivi topici; Tra tutti, il Tema della morte per acqua compare dalle sue prime alle ultime produzioni, compresa la narrazione su Chopin, e segnando coincidenze estetiche con alcuni dipinti dell'epoca (in particolare con l'Ofelia di Millais, nel corpo immerso nell'acqua e nel condizione di pre-morte).
Tenendo conto dell'intenso impatto che avranno gli scritti di George Sand sulla ricezione dell'immagine del compositore, questo articolo esamina alcuni aspetti che accompagneranno la rappresentazione pittorica e letteraria di Fryderyk Chopin e ipotizza che sul racconto del sogno chopiniano pesino più accorgimenti poetici che una totale aderenza alla realtà dei fatti.

The Philosophical Advantages of Whitehead's Physics: Explanation as Primary
Authors: Athearn Daniel 
Published: May 2022

Abstract
A. N. Whitehead's approach to physical theorizing contrasts with that of mainstream or official (modern) physics in being centrally concerned with articulating a background explanation of physical facts and phenomena in general that would take the place of the “ether” of classical physics, a project otherwise unpursued by the science in its modern period (though luminaries in the field have occasionally hinted at reviving this kind of explanation under certain constraints). Unlike Einstein's, Whitehead's approach to relativity primarily seeks explanation rather than utility (in formulating laws); also, it avoids the philosophical problems with Einstein's theory alleged by Whitehead and a range of other philosophers. This stops short of a finding as to the comparative worth of Whitehead's alternative basis for quantitative formulations.
Impostor phenomenon in healthcare simulation educators
Authors: Freeman Kirsty J , Houghton Stephen , Carr Sandra E , Nestel Debra 
Published: May 2022

Impostor phenomenon is the overwhelming feeling of intellectual phoniness and has been linked to decreased job satisfaction and increased levels of stress, depression and burnout. As education and healthcare institutions rely on simulation to train the current and future healthcare workforce, there is a need to improve our understanding of impostor phenomenon in the healthcare simulation context. This study investigated the prevalence of impostor phenomenon in simulation educators and examined the effect of work-related characteristics on impostor phenomenon in the simulation educator community.
In total, 148 simulation educators from nine countries participated in an online survey. Along with questions related to demographic characteristics, impostor phenomenon was measured using two scales, the Clance Impostor Phenomenon Scale (CIPS) and the Leary Impostorism Scale (LIS). Independent variables included gender, time spent on simulation activities per week, years working in simulation and team size.
Impostorism was identified in 46.6% of simulation educators. A multivariate analysis of variance revealed no statistically significant interactions or main effects of gender, time spent on simulation activities per week, years working in simulation and team size on impostor phenomenon. Impostor phenomenon does not discriminate based on gender; it does not disappear with experience; and it is present regardless of the size of team.
Impostor phenomenon is prevalent across the healthcare simulation educator community. Given the negative impact impostor phenomenon has on well-being and career development, educators, employers and professional societies need to acknowledge the prevalence of impostor phenomenon and start a conversation to build awareness about impostor phenomenon in the healthcare simulation community. Bringing the conversation into the open is the first step to acknowledging feelings of impostorism and developing strategies to break the cycle.

The term “Mangupa-upa” means giving gifts or holding salvation. When the Mangupa-upa ceremony is held at the residence of a person or a family, there are relatives of the family, as well as friends. In this event held a banquet together, conversation, and then the delivery of gifts to someone or family who formulated. Mangupa-upa events are carried out in accordance with the context of life experienced by a person or a family which in essence can be grouped into two categories, namely the mangupa-upa event relating to the atmosphere of joy or the atmosphere of sorrow. The basic for doing the form of event-forma or also called mangupa tondi aims to provide reinforcement to someone, or a family who is formatted in the process of dealing with all kinds of threats that might endanger themselves. Vergouwen argues that the purpose of mangupa-upa is essentially to strengthen soul/tondi, increase the power residing within humans, and to strengthen the bond between humans and their homes.
