O camarão-da-Amazônia Macrobrachium amazonicum (Heller, 1862) é uma espécie nativa amplamente distribuída na América do Sul. As relações biométricas possuem como finalidade estimar diferenças entre os sexos ou populações. Este estudo tem o objetivo de verificar a estrutura populacional com ênfase na razão sexual, relação peso-comprimento e fator de condição do camarão-da-Amazônia na foz do rio Amazonas. As coletas foram realizadas com armadilhas denominadas de matapi com espaçamento entre talas de (1, 2, 3, 4, 5, 6, 7, 8, 9, 10mm). Cada armadilha foi coberta com uma rede, denominada de sobrematapi. Foram registrados o comprimento da carapaça em centímetros e o peso individual em gramas de cada indivíduo. Do total de 19.967 camarões coletados 14.116 foram fêmeas, 5.806 machos e 45 de sexo indeterminado. As fêmeas variaram de 0,5 a 2,7 cm de comprimento da carapaça com média de 1,24 ± 0,47 cm e peso variando de 0,10 a 13,49 g com média de 2,09 ± 2,41 g. Para os machos a variação de comprimento foi de 0,5 a 3,3 cm com média de 1,50 ± 0,46cm, enquanto a variação de peso foi de 0,21 a 18,83 g com média de 3,19 ± 2,71 g. A variação de comprimento para os camarões de sexo indeterminado foi de 0,2 a 0,8cm com média de 0,68 ± 0,09 cm. O peso variou de 0,01 a 1,17 g com média de 0,26 ± 0,11 g. Os comprimentos da carapaça foram diferentes entre os meses e sexos. Os machos foram maiores que as fêmeas. A proporção entre os sexos foi muito diferente, sendo 2,43:1 (2,43 fêmeas para 1 macho). A proporção sexual foi diferente entre os meses, sendo as fêmeas mais abundantes. Os valores de b para machos e fêmeas diferem de 3, portanto os valores para ambos os sexos são menores que 3, indicando crescimento alométrico negativo em todos os meses. O fator de condição para machos e fêmeas diferiu de 1, quando comparados no geral entre os sexos, houve significância. Em todos os meses não houve diferença entre os sexos, exceto no mês de maio. O estudo da estrutura de população, com ênfase na relação peso-comprimento, proporção sexual e fator de condição, é uma importante ferramenta para entender a biologia de M. amazonicum.
Inclusão, Equidade, Seletividade: Que Justiça(S) Percorre (M) as Políticas Educativas e as Práticas Escolares?
Authors: Seiça Aline Bernardes
Published: February 2022

Tendo como horizonte de referênciaaAgenda 2030 para o desenvolvimento sustentável, recomendações da OCDE preconizam uma educação que forme “mão-de-obra competente e qualificada” pelo desenvolvimento de estratégias que articulem resultados da educação com necessidades das sociedades, visando “um crescimento inclusivo”. A ideia de que uma educação “de qualidade” e equitativa favorece a realização pessoal e promove o desenvolvimento económico sustenta essas recomendações. As políticas e a legislação educacionais portuguesas mais recentes denotam igualmente esta dupla finalidade e a ambivalência que a acompanha; a escola, dividida entre exigências de eficácia e sucesso e de inclusão de todos os alunos, de equidade e diversificação, enfrenta desafios de justiça que põem à prova diretores e professores quanto à capacidade de conjugação entre axiologias e éticas distintas, se não contraditórias. Integrando uma investigação de doutoramento sobre a problemática da justiça na escola, fundamentada em teorizações filosóficas e sociológicas de justiça, este artigo focaliza-se nos princípios e normas de justiça emergentes quer da legislação educacional quer dos documentos orientadores da escola.

Published: February 2022

The study investigated environmental accounting disclosure and financial performance of listed multinational companies in Nigeria. This study was conducted by firstly assessing the level of compliance, and then exploring the effect of environmental disclosure on financial performance with a focus on multinational companies in the face of continued environmental abuse witnessed in the Nigerian business space owing to the non-availability of sustainability reporting legal framework. The study used secondary data obtained from the published annual reports of the companies from 2011 to 2020. Data collected (Environmental disclosure index, return on asset, earnings per share), were analyzed using descriptive statistics and panel regression analysis. It was discovered that in assessing level of compliance, out of the three sectors assessed, oil and gas was the least compliant. Also, results showed that environmental accounting disclosure had a significant and positive effect on earnings per share (EAPS) but a negative and insignificant effect on return on asset (RETA). The study, therefore, concluded that the extent of responsiveness of companies to environmental accounting disclosure influences how the company is valued.The study, therefore, recommended that multinational companies and other Nigerian firms, should make effort to disclose their environmental-related activities even though it is not required by law, as it has shown evidence of its influence on earnings on shares of companies.

THE USE OF TIME DELAYS IN THE PRIMARY SOUND SIGNALS PROCESSING
Authors: МИШЕНКОВ С.Л. , ЕПИФАНОВА Е.С.
Published: February 2022

Показано, что применение современных многомикрофонных технологий первичной обработки звуковых сигналов приводит к уничтожению «глубинной» локализации звуковой картины в звуковых каналах вещания и при звукоусилении. Цифровые методы обработки сигналов позволяют дополнить звукорежиссерские пульты программами управляемых временных задержек сигналов от микрофонов и их групп, а также в канале реверберации. Анализируются значения временных задержек сигналов от источников при реальном исполнении и выбираются аналогичные значения задержек, которые обеспечивают глубинное восприятие звуковой картины и плавность их регулировок. Рекомендуется введение специальных индикаторов 2D/3D местоположения воспринимаемых слушателем источников звука.

It has been shown that the use of modern multi-microphone technologies of primary sound signals processing leads to the destruction of the "deep" localization of the sound picture in sound broadcasting channels and during sound amplification. Digital signal processing methods allow you to supplement the sound consoles with programs of controlled time delay signals from microphones and groups of microphones, as well as in the reverberation channel. The values of time delays of signals from sources in real performance are analyzed and similar delay values are selected, which provide a deep perception of the sound picture and smoothness of their adjustments. The introduction of special indicators of the 2D/3D location of sound sources perceived by the listener is recommended.

A Multi-Criteria Approach to Sustainable Risk Management of Supplier Portfolio: A Case Study at Defense Industry
Authors: ÖZTEK Gözde , KABAK Mehmet
Published: February 2022

Supply Chain Management plays an important role in the success and performance of businesses. Supply chains have to adapt to changes in technological advancements and customer expectations to maintain competitive advantage. On the other hand, driving factors such as risk reduction, increasing the financial performance of the supply chain, societal influence, governmental requirements and attracting customers who give importance to sustainability have been influential in the increasing interest in the concept of Sustainable Supply Chain. Therefore, businesses maintain their supply chain operations while focusing on economic, environmental and social dimensions. Additionally, the risk evaluation methods employed in supply chain management are considered to be more qualitative rather than quantitative. This study conducted in a Turkish defense industry company introduces a quantitative framework that allows the evaluation of risks and risk management practices required for sustainable supplier performance with the help of a Multi Criteria Decision Making (MCDM) approach. In this study, Analytical Hierarchy Process (AHP) and Rating Methods are applied together in order to evaluate risks through classification of critical suppliers with respect to business volume, capabilities and schedule certainty. Using this framework, Sustainable Supplier Risk Scores (SSRS) of each class of suppliers have been calculated and specific risk management practices have been determined for each class. The objective is to establish effective supply chain risk management practices, which provide long term partnership with suppliers in a business with strategic customers, high cost of production, high expectations in terms of quality and high level of supply chain risks.

Turismo médico: Revisión sistematizada de la literatura y evidencia
Authors:   , Ciupik Ana Celeste
Published: February 2022

Este trabajo realiza una revisión sistematizada de la literatura sobre turismo médico con el fin de conocer sus características principales y encontrar evidencia del mismo, para luego contribuir a la evidencia cuantitativa en el ámbito internacional. Para ambos objetivos se tiene particular interés en América Latina y Caribe y Argentina. El término turismo médico carece de una definición consensuada y las cuestiones de volumen e impacto son discutidas por la literatura de forma principalmente narrativa y teórica. Tres artículos seleccionados analizan el fenómeno en América Latina y Caribe, aunque no para Argentina y sin un análisis cuantitativo. Luego del análisis de las metodologías aplicadas en la literatura seleccionada, se toma como base a Loh (2013) para analizar las tendencias mundiales del turismo médico usando las series de viajes personales relacionados con la salud del Fondo Monetario Internacional para 2008-2017 e incorporando efectos fijos y variables de control al modelo de regresión lineal. No existe evidencia concluyente de una tendencia creciente de las importaciones y exportaciones de turismo médico. Los países de mayores ingresos son los que más comercian estas actividades. Casi todas las regiones superan en volumen de comercio internacional de turismo médico a América Latina y Caribe.

Últimamente se ha enriquecido la terapéutica de la Endocrinología con el descubrimiento de las drogas tiroinhibídoras del grupo del tiouracilo. De los estudios por los cuáles se ha llegado al conocimiento del tiouracilo y sus propiedades debe destacarse que las observaciones de Chesney y sus colaboradores, en el año 1918 se demostró que el repollo, administrado oomo dieta exclusiva a los conejos, era capaz do producir bocio en estos animales. Esta observación fue confirmada y ampliada por Marine, Bauman y Cipra en 1929, Mac Carrison en 1931, Spende en 1934 y posteriormente otros autores, que demostraron que también otros vegetales oono el repollito de Bruselas, el coliflor, etc. tenían propiedades bocígenas. Este fenómeno también se producía por la administración de hojas y semillas de berzas y semillas de colza, según fue demostrado por Marino y colaboradores en 1929, por Kennedy y Parres en 1941. Con ciertas reglones do la Europa Central, en la que la alimentación con repollo es predominante, se observa bocio endémico según fue comunicado por Suk en 1931.

The current patronages in the dyeing industry recent are going down and discouraging due to the black box effect of the dyes’ fastness and their reactive quality. This was not on unconnected with the exits of the older generations who are better adjudged experienced and well knowledgeable in the ionic and covalent bond structures of the existing ranges of fabrics in the market. This is done by making the right choice of the reactive dyes combinations or their preparations and applying the appropriate processing technologies implying skill issues. The broad objective of this study was to examine the effect of skill acquisition on the dyeing industry while the specific objective includes first investigating the effect of high education on the marginal returns in the dyeing industry. The second specific objective was to examine the effect of practice on the marginal returns in the industry. These two variables are considered crucial to organizational effective performance, particularly, in the dyeing industry. This survey was based on the population of 146 respondents drawn from the five zones (A to E, Abeokuta South Local Government) in the industry. The research method was quantitative. The research design was a cross-sectional one. The analysis technique used for the study was the multiple regression analysis. Stratified sampling techniques were adopted to carry out the research survey.The study revealed that practice as a variable had a very strong effect (found to be 0.2) on the marginal returns in the dyeing industry. High education also had a significant effect (abstracted to be 0.05) on the marginal returns in the dyeing industry. The study concluded that skill acquisition had a significant effect on the performance of the dyeing industry in terms of the marginal returns in the industry and therefore recommended that technical education should be subsidized or be free. Government should also encourage secondary and tertiary levels of education by an increase in the budget share of high vocational education. Measures for individuals, corporate organizations, and government revitalizing and preferring technical, and vocational training (TVET) to complement the conventional education type should be instituted by the policymakers, and the decision drivers, which will go a long way to aid the unemployed especially the university graduates as well as the other army of the jobless people.

The increasing global employee mortality rate has called for concern among organisations stakeholders, particularly the trade unions. This is because of high employee’s mortality rate caused by work-related accidents with resultant effect on death, injury and sometimes permanent occupational diseases. These developments have led to the creation of a compensation packages known as ‘Employment Injury Benefits’ for those employees’ that suffer fatal accident, but the administration and implementation of this schemes were erroneously carried out in some countries especially developing economies such as Nigeria. This paper examines administration and implementation of the Employment Injury Benefits (EIB) in Nigeria. It also seeks to find out objectives of the EIB viz-a-viz its main scope as a compensation mechanism for employees with injuries, diseases and even death. Descriptive research method is employed to review Employees’ Compensation Act of 2010 and its relationship with ILO Convention 121 of 1964. This approach helps to achieve employee protection, promote sustainable employee security, wellbeing and development. The paper concludes by discussing the procedure for laying claims and the challenges facing the EIB as well as suggesting solutions in order to achieve sustainable society in Nigeria context.
Statistical-mechanical analysis of adaptive filter with clipping saturation-type nonlinearity
Authors: Miyoshi Seiji
Published: February 2022

In most practical adaptive signal processing systems, e.g., active noise control, active vibration control, and acoustic echo cancellation, substantial nonlinearities that cannot be neglected exist. In this paper, we analyze the behaviors of an adaptive system in which the output of the adaptive filter has the clipping saturation-type nonlinearity by a statistical-mechanical method. We discuss the dynamical and steady-state behaviors of the adaptive system by asymptotic analysis, steady-state analysis, and numerical calculation. As a result, it has become clear that the saturation value has the critical point at which the system's mean-square stability and instability switch. The obtained theory well explains the strange behaviors around the critical point observed in the computer simulation. Finally, the exact value of the critical point is also derived.
On the Impact of Probabilistic Shaping on Fiber Nonlinearities
Authors: Tanha Ahmad , Rabbani Hami , Beygi Lotfollah
Published: February 2022

This paper addresses probabilistic shaping (PS) which has been a latest key technique to approach capacity of fiber-optic channels. We investigate the impact of PS on nonlinear interference (NLI), including self channel interference (SCI), cross channel interference (XCI), and multi channel interference (MCI) for a polarization multiplexed 16-ary quadrature amplitude modulation format in a wavelength division multiplexed (WDM) system. To this end, we consider performing PS in two scenarios: (i) Solely on the channel of interest and (ii) over all C-band WDM channels of a fiber-optic link by analyzing the effective signal to noise ratio and symbol error rate. It is demonstrated that using the enhanced Gaussian noise model with merely 10% overhead in the first scenario, the applied PS scheme increases the SCI and the total experienced NLI by about 19.23%, and 6.6%, respectively. Interestingly, despite enhancing the NLI in this scenario, the simulated PS technique leads to about 47.6% increase in the transmission reach. In the second scenario, the numerical results show increase of the SCI, XCI, and total NLI around 19.8%, 23.34%, and 20.2%, respectively, but resulting in an increase of 32.3% in the transmission reach.

Published: February 2022

Non-orthogonal multiple access (NOMA) has received an enormous attention in the recent literature due to its potential to improve the spectral efficiency of wireless networks. For several years, most of the research efforts on the performance analysis of NOMA were steered towards the ergodic sum rate and outage probability. More recently, error rate analysis of NOMA has attracted massive attention and sparked massive number of researchers whose aim was to evaluate the error rate of the various NOMA configurations and designs. Therefore, the large number of publications that appeared in a short time duration made highly challenging for the research community to identify the contribution of the different research articles. Therefore, this work aims at surveying the research work that considers NOMA error rate analysis and classifying the contributions of each work. Therefore, work redundancy and overlap can be minimized, research gabs can be identified, and future research directions can be outlined. Moreover, this work presents the principles of NOMA error rate analysis.

Authors: Iqbal Muhammad Zahid , Fuchs Beatrice , Hahn Nathan , Fortna Max , Cobb Elijah
Published: February 2022

Invasion of locust swarms has affected the crops in
many countries in Africa and Asia which is a major threat to food
security. According to the Food and Agriculture Organization
(FAO), locusts have the ability to fly over 130 km a day and stay
in the air for a long time. There are different approaches adopted
in the different parts of the world to monitor and control the
locust swarms to save the crops. It has been proved in various
studies that technology can help in agriculture through drones,
real-time data monitoring or teaching the farmers with latest
tools.
Following the UN sustainability goals for food security, this
research has presented a virtual reality based educational game
to teach sustainable locust management strategies. Hand tracking
technology in the Oculus Quest enables users to learn the
ways that farmers deal with pests without using pesticides. The
methods shown are not only profitable for the farmers but also
free of any harm for crops in terms of food security. This game
can help to motivate the adoption of these sustainable locust
control strategies in broader interventions for environmental
recovery.
Miniaturized Fully-Passive Wireless Neural Recording with Heterogeneous Integration in Thin Packages
Authors: Been Sayeed Sk Yeahia , Pulugartha Markondeyaraj
Published: February 2022

Wireless
fully-passive neural recording systems are demonstrated with heterogeneous
integration of sensing, mixing and communication components in flexible polymer
dielectric films. The recording neurosensor has an antenna, antiparallel diode,
and a by-pass capacitor to modulate an incoming carrier signal with the neuropotentials
and backscatter the mixed signal to an external reader circuit. Planar antennas
are realized on Liquid Crystal Polymer (LCP) flexible substrates with low dielectric
constant. The designed antenna topology is
realized with a single metal layer and eliminates the dependency on substrate
thickness and leads to thinner sensors. This is a major advance compared to
prior passive neural recording with rigid and thicker substrates and components.
Approximately 80% thickness reduction and 20% volume reduction are achieved
with similar performance compared to earlier studies. Our approach thus leads
to low-cost and disposable wireless neurosensors on a flexible platform with
heterogenous integration.

The COVID-19 pandemic has caused a significant set of challenges for healthcare providers. Therefore, it is of utmost importance to determine the anxiety, depression, stress, and burnout levels of employees and to identify subfactors that directly impact physicians’ well-being. This is a cross-sectional online survey evaluating the impact of the COVID-19 pandemic on work-life balance, in particular, psychological distress on practising primary care physicians at Primary Healthcare Corporation, Qatar. We designed an online survey using the stress component of DASS-21, GAD-7, PHQ-9, and the Stanford Professional Fulfilment Index (PFI). A total of 150 (21%), of which 58.7% were males and 47% were 25-44 years old, completed the questionnaire. Stress was reported by (26.7%), anxiety (32.7%), depression (45.3%), burnout (38.7%) and low professional fulfilment (80%). Stress and burnout were more prevalent among physicians aged < 44 years. Physicians who were concerned about the impact of COVID-19 on themselves reported higher levels of stress, anxiety, and depression (p < .05). Physicians who expressed burnout were more likely to order the wrong medication (p = .046) and those with stress, anxiety, and depression were more likely to cause major medical errors that could have resulted in patient harm (p <.05). The level of satisfaction with salary was associated with stress (p = .047) and depression (p = .005). Telephone consultation dissatisfaction was significantly associated with stress (p = .006), anxiety (p = .028), depression (p = .010) and burnout (p = .038). Gender, marital status, number of dependents, choice of the medical profession willingly or unwillingly, availability of PPE, and the rapidly changing COVID-19 guidelines were not associated with the variables. Stress, anxiety, depression, burnout, and low professional fulfilment were common among PHCC physicians. The PHCC has an excellent support system for primary care physicians. However, further effective co

Malignant mesotheliomas are rare types of cancers that affect the mesothelial surfaces, usually the pleura and peritoneum. They are associated with asbestos exposure, but due to a latency period of more than 30 years and difficult diagnosis, most cases are not detected until they reach advanced stages. Treatment options for this tumor type are very limited and survival ranges from 12 to 36 months. This review discusses the molecular physiopathology, current diagnosis, and latest therapeutic options for this disease.

كان رابح بن فضل الله واحدا من ضباط الزعيم السوداني المعروف الزبير باشا رحمة منصور، الذي تمكن من اقامة امارة خاصة به في أقليم بحر الغزال ثم امتدت لتشمل كردفان ودارفور ، وبسبب التحريض البريطاني باتهامه بتجارة الرقيق بدأت السلطات المصرية في الخرطوم بمضايقته ، فرحل مع حاشية ضخمة الى القاهرة ليؤكد للخديوى اسماعيل بانه موال لمصر وليس لديه اية نوايا انفصالية ، لكنه احتجز هناك ومنع من العودة ، فتولى ابنه سليمان ادارة البلاد الا ان غوردون حاكم السودان مالبث ان دبر ضده مؤامرة فاتهمه بمحاولة الانفصال هو الآخر، وارسل اليه قوة بقيادة الضابط الايطالي جسي ، وبناء على نصيحة والده الزبير استسلم سليمان لجسي مؤكدا حسن نواياه الا ان الأخير سرعان ما غدر به وقتله مع عدد من اقاربه ، وكان رابح احد ضباط سليمان البارزين الذي لم يأمن جانب هؤلاء الاجانب فرفض الاستسلام مع سليمان ، واتجه غربا مع نحو الف مقاتل من اتباعه المسلحين بالبنادق ، واستولى على مناطق متعددة في جنوب مملكة وداي ثم اخذ يتوسع تدريجيا حتى تمكن من تكوين مملكة واسعة سنة 1892ضمت اجزاء من مملكة وداي وكل من مملكتي باكرمي وبرنو واجزاء من مملكة سوكوتو، واتخذ من مدينة دكوة عاصمة له ، وشكل جيشا قويا وبذلك اسس او دولة عربية اسلامية حديثة في تشاد واجزاء من الكامرون والنيجر الحالية ، وهذا ما ادى الى اصطدامه بالتغلغل الاستعماري الفرنسي في وسط القارة الافريقية ودارت بينهما معارك طاحنة استمرت على مدى ثماني سنوات انتهت باستشهاد رابح والقضاء على مملكته سنة 1900 بعد ان استقدمت فرنسا قوات كبيرة من الجزائر وغرب افريقيا . فتولى ابنه فضل الله قيادة المقاومة العربية هناك حتى استشهد هو الاخر سنة 1902.
تحليل الرواية المكسيكية "مثل الماء للشوكولاتة" لورا اسكويفيل
Authors: Abd Mithal Ahmed

يمتاز الأدب بشكل عام سواء الأدب الإسباني أو الأدب العالمي بوجود الكثير من الشخصيات الأدبية العملاقة التي تمكنت من إدارة عملها المستمر الذي يترك انطباعًا دائمًا وواضحًا في جميع مجالات العالم الأدبي عبر التاريخ ، ومن بين هؤلاء الكتاب يمكننا أن نذكر الكاتبة المكسيكية (Laura Esquivel) التي وضعت لمسات أدبية واضحة ودقيقة من خلال روايتها الشهيرة (مثل ماء الشوكولاتة) (como agua para chocolate) ، هذه الدراسة تدور حولها. الرواية (مثل الماء للشوكولاتة) (como agua para chocolate) هي واحدة من القصص المثيرة التي تدين بإلهامها والتي تتمتع بسمعة طيبة. تروي هذه الرواية إحساس الطفلة الرقيقة (تيتا) وهي من الشخصيات الرئيسية التي تدور حول أحداث هذه الرواية ، حيث أنهم يرون بأعينهم كيف يتزوج صديقها (بيدرو) من أختها (روزورا) ، وفي ذلك الوقت يجب عليهم ذلك. الاستمرار في العمل في المطبخ ، حيث يجب احترام التقاليد التي كانت سائدة في ذلك الوقت ، والتي تنص على أن الفتاة يجب أن تظل متناهية الصغر دون زواج لمساعدة والدتها في الأعمال المنزلية. الجدير بالذكر أن عنوان هذه الرواية مشهور مثله تناوله السكان في بلدان أمريكا اللاتينية وخاصة في المكسيك. كنت أبحث عن هذا التحليل الجديد الذي يشمل كل شيء افتراضيًا وصوفيًا ، لا سيما تلك المتعلقة بالظروف الاجتماعية التي سادت في هذه الفترات. ووجد البحث أن هذه الرواية وبواسطة الكثير من النقاد والباحثين هي من الجواهر الأدبية سواء على المستوى المحلي أو المستوى العالمي حيث تمتزج بين ما هو دنيوي وما هو خارق من خلال تناولها لواقع الساحر. لتلك البنية الاجتماعية السائدة في ذلك الوقت. وقد حير النقاد الباحثين إذا أرادوا البدء في تصنيف هذه الرواية ، ورأى بعضهم أنها من الأعمال التاريخية ، لأنها شرعت في جمع الكثير من العادات والتقاليد في تلك الفترة. ومنهم من يعد بعمل رومانسي ، فهو يروي حياة وصعوبات الجنس اللطيف ، ويعرضه للصعوبات والمآسي ، خاصة النساء اللواتي يعملن كما يكرسن حياتهن للعمل في المطبخ. ومنهم من يعد من كتبه للطبخ لأنه يحتوي على الكثير من الوصفات السحرية الخاصة بالمطبخ.
Hannah Arendt e o nascimento dos conselhos
Authors: Neves Barbosa Vicente José João
Published: February 2022

Em sua teoria política, especialmente em sua obra Da revolução, Hannah Arendt não apenas analisou e discutiu o sentido e o significado das revoluções (especialmente a Francesa e a Americana) e criticou o funcionamento da democracia representativa baseada no sistema de partidos políticos, mas também destacou os conselhos como espaços propícios onde os homens possam agir por meio de ação e do discurso, na presença de seus pares e se ocuparem juntos da vida política de seu país. Neste artigo, o objetivo principal é analisar o nascimento desses conselhos à luz da teoria política de Hannah Arendt, como verdadeiros espaços de liberdade que sempre surgiram no curso das grandes revoluções de forma espontânea e fora do âmbito dos partidos políticos ou de qualquer líder e que podem proporcionar aos cidadãos condições para uma efetiva participação política.
