Development Paradigm for Ecological Civilization and Reform of Economics Theory Towards Ecological Development
Authors: PAN Jiahua
Published: December 2020

In the context of integrating the ecological development into all aspects and the whole process of economic, political, cultural and social development, and striving to create a new era of China’s socialist ecological civilization, one important aspect is that we need to construct a paradigm transformation theory for the development of ecological civilization. In establishing theories for the paradigm of ecological development, what we need most is an economic theory. However, the problem is that traditional and conventional economics, including political economics, cannot provide theoretical and methodological support for the current ecological development in China or even the world. Based on the concept, cognition and China’s practice of ecological civilization, the author reflects on the economic theory and its development direction in future.

Published: December 2020

Cardiovascular disorders cause nearly one in three deaths in the United States. Short- and long-term care for these disorders is often determined in short-term settings. However, these decisions are made with minimal longitudinal and long-term data. To overcome this bias towards data from acute care settings, improved longitudinal monitoring for cardiovascular patients is needed. Longitudinal monitoring provides a more comprehensive picture of patient health, allowing for informed decision making. This work surveys sensing and machine learning in the field of remote health monitoring for cardiovascular disorders. We highlight three needs in the design of new smart health technologies: (1) need for sensing technologies that track longitudinal trends of the cardiovascular disorder despite infrequent, noisy, or missing data measurements; (2) need for new analytic techniques designed in a longitudinal, continual fashion to aid in the development of new risk prediction techniques and in tracking disease progression; and (3) need for personalized and interpretable machine learning techniques, allowing for advancements in clinical decision making. We highlight these needs based upon the current state of the art in smart health technologies and analytics. We then discuss opportunities in addressing these needs for development of smart health technologies for the field of cardiovascular disorders and care.

Authors: Milosz Marek , Kęsik Jacek , Montusiewicz Jerzy
Published: December 2020

The development of information technology (IT) now allows for rapid, semi-automatic digitization of cultural heritage objects, both typical museum exhibits and architectural monuments. However, the same IT development makes it possible to disseminate the results of digitization, i.e., to reach a wide audience. This article presents the methodology of 3D scanning and processing of the acquired data on the surface condition of large architectural objects to develop their models and make various variants of their visualization. The developed methodology was divided into many stages and steps. It provides methods, techniques, and recommendations on how to solve specific problems that interfere with the process of data acquisition under typical conditions of continuous access to the objects by tourists and the impossibility of turning the object off from the visitors. The methodology prepared was used and tested during field trips to Kazakhstan and Uzbekistan in 2018--2019 to prepare digital visualizations of objects belonging to the group of monuments called Timurid architecture. Preparation and
in situ
verification of 3D data acquisition procedures under different traditions, cultures, religions, customs, administrative procedures, time constraints, technical resources, and climatic conditions is of great importance for effectively equipping research expeditions dealing with the digitization of architecture in different areas of the world.

Published: December 2020

The antipsychotic medication olanzapine causes rapid and large increases in blood glucose. We demonstrate that a prior bout of voluntary overnight wheel running can protect against this harmful side effect and is likely mediated by reductions in olanzapine-induced increases in the circulating glucagon to insulin ratio. This study highlights the powerful effects of voluntary activity in conditions of treatment with antipsychotic medications.

Published: December 2020

Purpose. To report on an improved botulinum toxin injection with conjunctival microincision for beginners, and to determine the effectiveness of botulinum toxin A (BTXA) in the treatment of patients with acute acquired comitant esotropia (AACE). Methods. Medical records of 29 AACE patients were retrospectively analyzed. BTXA was injected into the unilateral or bilateral medial rectus muscle with conjunctival microincision without electromyographic guidance. Success was defined as total horizontal deviation ≤10 prism diopters (PD) and evidence of binocular vision. Results. Twenty-nine patients were included, of whom 22 were male and 7 were female. The mean age at onset was 14.2 ± 7.4 (range, 4–34) years. The mean time from onset of AACE to injection was 18.4 ± 20.3 (range, 1–96) weeks. All patients completed at least 6 months of follow-up, and the mean follow-up after BTXA injection was 12.3 ± 4.8 months (range, 7–24 months). Neurological evaluation and brain magnetic resonance imaging (MRI) were unremarkable in all patients. The mean spherical equivalent refraction was −1.22 ± 2.85D and −0.97 ± 2.80D in the right and left eyes, respectively. Mean preinjective esotropia was 38.4 ± 18.9 PD (range, +10–+80 PD) at near and 40.2 ± 17.7 PD (range, +20–+80 PD) at far distance. The mean angle of deviation at 6 months after injection was 0.6 ± 4.1 PD (range, −3–+15 PD) at near and 3.0 ± 5.9 PD (range, 0–+20 PD) at far distance. There was significant difference in the angle of deviation at near and far fixation between pre-BTXA and post-BTXA 6 months (p<0.001,p<0.001, resp.). There was no significant difference in the angle of deviation at near and far fixation between post-BTXA 6 months and post-BTXA at final follow-up (p = 0.259 and 0.326, resp.). Mean stereoacuity improved from 338 to 88 arc seconds. During the follow-up period, 5 of 29 patients had recurrent esotropia. Two patients refused all further treatment, and the other 3 patients required incisional strabismus surgery. The success rates were 86.2% (25/29) at 6 months and 82.8% (24/29) at final follow-up. Conclusion. Conjunctival microincision injection of botulinum toxin is a practical and safe method for beginners to locate an extraocular muscle, which is as effective as the traditional methods. Botulinum toxin injection can be preferred as the first-line treatment for AACE patients with potential binocular vision.
A Gradient-Based Recurrent Neural Network for Visual Servoing of Robot Manipulators with Acceleration Command
Authors: Huang Zhiguan , Xie Zhengtai , Jin Long , Li Yuhe
Published: December 2020

Recent decades have witnessed the rapid evolution of robotic applications and their expansion into a variety of spheres with remarkable achievements. This article researches a crucial technique of robot manipulators referred to as visual servoing, which relies on the visual feedback to respond to the external information. In this regard, the visual servoing issue is tactfully transformed into a quadratic programming problem with equality and inequality constraints. Differing from the traditional methods, a gradient-based recurrent neural network (GRNN) for solving the visual servoing issue is newly proposed in this article in the light of the gradient descent method. Then, the stability proof is presented in theory with the pixel error convergent exponentially to zero. Specifically speaking, the proposed method is able to impel the manipulator to approach the desired static point while maintaining physical constraints considered. After that, the feasibility and superiority of the proposed GRNN are verified by simulative experiments. Significantly, the proposed visual servo method can be leveraged to medical robots and rehabilitation robots to further assist doctors in treating patients remotely.
Preeclampsia and the Risk of Pancreatitis: A Nationwide, Population-Based Cohort Study
Authors: Huang Jia-Lun , Chen Wei-Kung , Lin Cheng-Li , Kao Chia-Hung , Shih Hong-Mo
Published: December 2020

Background. Preeclampsia is a multiple organ dysfunction during pregnancy, including hepatic, renal, and neurological dysfunction, and is defined as hypertension and proteinuria occurring after 20 weeks of pregnancy. Clinical features seen in preeclampsia are due to relatively poorly perfused placenta and maternal endothelial dysfunction. Some studies have found that preeclampsia may cause acute pancreatitis due to microvascular abnormalities and visceral ischemia. This retrospective cohort study used the Taiwanese National Health Insurance Research Databases (NHIRD) to study the relationship between preeclampsia and the risk of pancreatitis. Methods. In total, 606,538 pregnant women were selected from the NHIRD between January 1, 1998 and December 31, 2010. They were divided into a preeclampsia cohort (

n
=
485,211

) and a nonpreeclampsia cohort (

n
=
121,327

). After adjusting for comorbidities that may induce pancreatitis, we analyzed and compared the incidence of pancreatitis in the two cohorts. Results. The overall incidence of pancreatitis in the preeclampsia cohort was significantly higher than that in the control cohort (4.29 vs. 2.33 per 10,000 person-years). The adjusted HR of developing pancreatitis increased 1.68-fold (95% CI: 1.19-2.36) in the preeclampsia cohort. In addition, pregnant women with preeclampsia without comorbidities had a significantly high risk of pancreatitis (

aHR
=
1.83

, 95% CI 1.27-2.63). The combined effect of preeclampsia and alcohol-related diseases resulted in the highest risk of pancreatitis (

aHR
=
43.4

, 95% CI: 6.06-311.3). Conclusion. Compared with patients without preeclampsia, the risk of pancreatitis in patients with preeclampsia is significantly increased after adjusting for demographics and comorbidities. The risk of pancreatitis is greatly increased when preeclampsia is accompanied by alcohol-related diseases, hepatitis C, gallstones, diabetes, or age of 26–35 years. Early identification and effective control of preeclampsia and the associated comorbidities can reduce the risk of pancreatitis and the associated morbidity and mortality.

Authors: Oroojan Ali Akbar , Chenani Narges , An’aam Marzieh
Published: December 2020

Background. The antioxidant system in islets of Langerhans is weak, which can lead to diabetes. Meanwhile, the main component of cloves that produce antioxidant effects is eugenol. Accordingly, the present study was conducted to investigate the antioxidant effect of eugenol on oxidative stress induced by hydrogen peroxide (H2O2) in islets of Langerhans isolated from the male mice. Materials and Methods. In this experimental study, adult Naval Medical Research Institute (NMRI) mice (20-25 g) were prepared. The collagenase digestion method was used for dissecting the islets of Langerhans. H2O2 50 μM was administered for 30 min to induce oxidative stress, with 50, 100, and 200 μM of eugenol employed for 2 hours before the administration of H2O2. The experimental groups were divided into five groups: (control, H2O2, and H2O2+eugenol 50, 100, and 200 μM). Finally, the islet’s lipid peroxidation and antioxidants levels were measured by the ELISA assay method. Results. Malondialdehyde (MDA), total antioxidant capacity (TAC), superoxide dismutase (SOD), and catalase (CAT) increased in all groups when compared to the control (

P
<
0.05

). MDA diminished in H2O2+eugenol 50, 100, and 200 μM (

P
<
0.01

) groups versus the H2O2. TAC was elevated when eugenol 50, 100, and 200 μM was administered in oxidative stress-induced islets (

P
<
0.001

). Also, CAT increased in the H2O2+eugenol 50 (

P
<
0.05

) group in comparison with the H2O2 group. Conclusions. In conclusion, H2O2 induced oxidative stress and lipid peroxidation in the islets, and administration of eugenol recovered these alterations by raising the level of TAC and CAT, while reducing MDA as a lipid peroxidation biomarker.

Published: December 2020

This paper deals with the reference trajectory tracking problem and simultaneous active disturbance suppression on a class of controlled aerial mechanical systems by processing measurable output signals. A novel dynamic control method for desired motion reference trajectory tracking for quadrotor helicopters is introduced. Measurements of position output signals for efficient and robust tracking of motion profiles specified for the unmanned aerial vehicle are only required. Thus, differentiation of signals and real-time estimation of disturbances affecting the multi-input multioutput, underactuated nonlinear dynamic system are unnecessary. The presented active control approach can be directly extended for a class of vibrating mechanical systems. Analytical, experimental, and numerical results are presented to prove the satisfactory performance of the proposed trajectory tracking control approach for considerably perturbed operating scenarios.

Published: December 2020

Retinopathy is one of the most severe diabetes-related complications, and macular edema is the major cause of central vision loss in patients with diabetes mellitus. Significant progress has been made in recent years in optical coherence tomography and angiography technology. At the same time, various parameters have been attributed the role of biomarkers creating the frame for new monitoring and treatment strategies and offering new insights into the pathogenesis of diabetic retinopathy and diabetic macular edema. In this review, we gathered the results of studies that investigated various specific OCT (angiography) parameters in diabetic macular edema, such as central subfoveal thickness (CST), cube average thickness (CAT), cube volume (CV), choroidal thickness (CT), retinal nerve fiber layer (RNFL), retinal thickness at the fovea (RTF), subfoveal choroidal thickness (SFCT), central macular thickness (CMT), choroidal vascularity index (CVI), total macular volume (TMV), central choroid thickness (CCT), photoreceptor outer segment (PROS), perfused capillary density (PCD), foveal avascular zone (FAZ), subfoveal neuroretinal detachment (SND), hyperreflective foci (HF), disorganization of the inner retinal layers (DRIL), ellipsoid zone (EZ), inner segment/outer segment (IS/OS) junctions, vascular density (VD), deep capillary plexus (DCP), and superficial capillary plexus (SCP), in order to provide a synthesis of biomarkers that are currently used for the early diagnosis, assessment, monitoring, and outlining of prognosis.

Published: December 2020

The comprehensive and effective utilization of multiple renewable sources involving water, solar, and other energies have been receiving more and more attention, and the coordinated dispatching considering multiple uncertainties has become one of the research focuses currently. To cope with the stochastic dispatching of cascaded hydro-PV-PSH (pumped storage hydropower, PSH) complementary power generation system, this paper has proposed a two-stage optimized dispatching method combining uncertainties simulation and complementary dispatching schemes optimization. Firstly, a modified PCPS (probabilistic chronological production simulation) method is proposed to simulate the uncertain power output of each energy type, and thus the complementary dispatching schemes and performance parameters are obtained. In the simulation process, a special treatment method combining overall uncertainties, overall dispatching measures, and interstage distribution for cascaded hydropower stations is given out. Secondly, a dual-objective optimized model considering reliability and economic performance and MOQPSO algorithm is introduced to calculate the optimal Pareto solution set of stochastic dispatching schemes. The results of the case study verified the feasibility and calculating performance of the proposed method in developing optimized dispatching schemes.

Two improved bispectrum methods are proposed based on fractional lower-order covariation in this paper, including fractional low-order direct bispectrum (FLODB) method, fractional low-order indirect bispectrum (FLOIDB) method. In order to decrease the estimate variance and increase the bispectral flatness, the fractional lower-order autoregression (FLOAR) model bispectrum and fractional lower-order autoregressive moving average (FLOARMA) model bispectrum methods are presented, and their calculation steps are summarized. We compare the improved bispectrum methods with the conventional methods employing second-order statistics in Gaussian and

Finally, we use the improved methods to estimate the bispectrum of the normal and outer race fault signal; the result indicates that they are feasible and effective for fault diagnosis.
Identification of 5‐Gene Signature Improves Lung Adenocarcinoma Prognostic Stratification Based on Differential Expression Invasion Genes of Molecular Subtypes
Authors: Zheng Zhimin , Deng Weijie , Yang Jiansheng
Published: December 2020

Background. The acquisition of invasive tumor cell behavior is considered to be the cornerstone of the metastasis cascade. Thus, genetic markers associated with invasiveness can be stratified according to patient prognosis. In this study, we aimed to identify an invasive genetic trait and study its biological relevance in lung adenocarcinoma. Methods. 250 TCGA patients with lung adenocarcinoma were used as the training set, and the remaining 250 TCGA patients, 500 ALL TCGA patients, 226 patients with GSE31210, 83 patients with GSE30219, and 127 patients with GSE50081 were used as the verification data sets. Subtype classification of all TCGA lung adenocarcinoma samples was based on invasion‐associated genes using the R package ConsensusClusterPlus. Kaplan‐Meier curves, LASSO (least absolute contraction and selection operator) method, and univariate and multivariate Cox analysis were used to develop a molecular model for predicting survival. Results. As a consequence, two molecular subtypes for LUAD were first identified from all TCGA all data sets which were significant on survival time. C1 subtype with poor prognosis has higher clinical characteristics of malignancy, higher mutation frequency of KRAS and TP53, and a lower expression of immune regulatory molecules. 2463 differentially expressed invasion genes between C1 and C2 subtypes were obtained, including 580 upregulation genes and 1883 downregulation genes. Functional enrichment analysis found that upregulated genes were associated with the development of tumor pathways, while downregulated genes were more associated with immunity. Furthermore, 5‐invasion gene signature was constructed based on 2463 genes, which was validated in four data sets. This signature divided patients into high‐risk and low‐risk groups, and the LUDA survival rate of the high‐risk group is significantly lower than that of the low‐risk group. Multivariate Cox analysis revealed that this gene signature was an independent prognostic factor for LUDA. Compared with other existing models, our model has a higher AUC. Conclusion. In this study, two subtypes were identified. In addition, we developed a 5‐gene signature prognostic risk model, which has a good AUC in the training set and independent validation set and is a model with independent clinical characteristics. Therefore, we recommend using this classifier as a molecular diagnostic test to assess the prognostic risk of patients with LUDA.
Hydrogen Sulfide Protects Retinal Pigment Epithelial Cells from Oxidative Stress-Induced Apoptosis and Affects Autophagy

Published: December 2020

Age-related macular degeneration (AMD) is a major cause of visual impairment and blindness among the elderly. AMD is characterized by retinal pigment epithelial (RPE) cell dysfunction. However, the pathogenesis of AMD is still unclear, and there is currently no effective treatment. Accumulated evidence indicates that oxidative stress and autophagy play a crucial role in the development of AMD. H2S is an antioxidant that can directly remove intracellular superoxide anions and hydrogen peroxide. The purpose of this study is to investigate the antioxidative effect of H2S in RPE cells and its role in autophagy. The results show that exogenous H2S (NaHS) pretreatment effectively reduces H2O2-induced oxidative stress, oxidative damage, apoptosis, and inflammation in ARPE-19 cells. NaHS pretreatment also decreased autophagy levels raised by H2O2, increased cell viability, and ameliorated cell morphological damage. Interestingly, the suppression of autophagy by its inhibitor 3-MA showed an increase of cell viability, amelioration of morphology, and a decrease of apoptosis. In summary, oxidative stress causes ARPE-19 cell injury by inducing cell autophagy. However exogenous H2S is shown to attenuate ARPE-19 cell injury, decrease apoptosis, and reduce the occurrence of autophagy-mediated by oxidative stress. These findings suggest that autophagy might play a crucial role in the development of AMD, and exogenous H2S has a potential value in the treatment of AMD.
A Dynamic Opposite Learning Assisted Grasshopper Optimization Algorithm for the Flexible JobScheduling Problem
Authors: Feng Yi , Liu Mengru , Zhang Yuqian , Wang Jinglin
Published: December 2020

Job shop scheduling problem (JSP) is one of the most difficult optimization problems in manufacturing industry, and flexible job shop scheduling problem (FJSP) is an extension of the classical JSP, which further challenges the algorithm performance. In FJSP, a machine should be selected for each process from a given set, which introduces another decision element within the job path, making FJSP be more difficult than traditional JSP. In this paper, a variant of grasshopper optimization algorithm (GOA) named dynamic opposite learning assisted GOA (DOLGOA) is proposed to solve FJSP. The recently proposed dynamic opposite learning (DOL) strategy adopts the asymmetric search space to improve the exploitation ability of the algorithm and increase the possibility of finding the global optimum. Various popular benchmarks from CEC 2014 and FJSP are used to evaluate the performance of DOLGOA. Numerical results with comparisons of other classic algorithms show that DOLGOA gets obvious improvement for solving global optimization problems and is well-performed when solving FJSP.

The purpose of this paper is modelling and controlling the spread of COVID-19 disease in Morocco. A nonlinear mathematical model with two subclasses of infectious individuals is proposed. The population is divided into five classes, namely, susceptible (S), exposed (E), undiagnosed infectious (

I

n
c

), diagnosed patients (

I

c

), and removed individuals. To reflect the real dynamic of the COVID-19 transmission in Morocco, the real reported data are used for estimating model parameters. Two controls representing screening effort and limited treatment are considered. Based on viability theory and set-valued analysis, a Lyapunov function is constructed such that both exposed and infected populations are decreased to zero asymptotically. The corresponding controls are derived via a continuous selection of adequately designed feedback map. Numerical simulations are presented with three scenarios (cases when each control is used alone and the case when two controls are combined). Our results show that when only one control is to be applied, screening is the most effective in decreasing the number of people in the three infected compartments, whereas combining both controls is found to be highly effective and leads to a significant improvement in the epidemiological situation of Morocco. To the best of our knowledge, this work is the first one that applies the set-valued approach to a controlled COVID-19 model which agrees with the observed cases in Morocco.
Multiálogo e arco tenso: poemas intermídia de Décio Pignatari
Authors: Bomfim Monalisa Medrado
Published: December 2020

Décio Pignatari (1927-2012) era o mais irreverente do trio de poetas concretos que compunha junto com os irmãos Haroldo e Augusto de Campos. A ousadia de Pignatari está na sátira, mas também no multiálogo das mídias, que ele experimenta por meio de diferentes suportes nos poemas intermídia. O objetivo do trabalho foi trazer a poesia de Décio Pignatari para o campo de análise do suporte de inscrição, sugerindo um diálogo ativo com o contemporâneo digital. Observa-se que existe algum dado tecnomoderno nos poemas intermídia um movimento (1956), hombre hambre hambra (1957) e caviar (1959), que transitam entre os suportes da página e do áudio. Para compor a discussão teórica do conceito de intermídia foram utilizados os textos: Inter textos/ inter artes/ inter media (2006) e Concrete poetry and the new performance arts: intersemiotic, intermedia, intercultural (2000), de Claus Clüver. Já os textos: A poesia concreta como precursora da cibercultura (2006) e Décio Pignatari entre a vida, os signos e a memória (2016), de Lucia Santaella, articularam o diálogo entre os poemas e o contexto digital.

Nesta conversa realizada em meio à crise gerada pela Covid-19, a entrevista tece considerações a respeito de sua relação com José Saramago, da possibilidade de a pandemia ser uma nova cegueira, e mesmo se o escritor português teria previsto esta distopia presente. Focada nas Humanidades em geral, a entrevista abrange vários temas importantes, como a distopia, o papel da literatura e o processo de escrita de Saramago, o lugar das memórias, passa pelos projetos de vida, pela busca da autoafirmação, alcançando também outros escritores, como Fernando Pessoa e Miguel de Cervantes.
Três poemas de procura
Authors: Mostazo João
Published: December 2020

Os três poemas aqui apresentados elaboram, cada um à sua maneira, a ideia da literatura como encontro. Em "A bússola", reflete-se sobre a possibilidade de que o ato poético ou a escrita sejam capazes de promover o encontro com o leitor a partir da criação de um símbolo. O poema, em busca desse símbolo, procede a partir de um movimento de construção/desconstrução da imagem de uma bússola, inserindo-se em uma tradição de poemas que poderíamos chamar de "poemas de procura". Em "O mesopotâmio", a procura pelo encontro se dá não no espaço, mas no tempo. Em "Se soubéssemos diríamos melhor", pergunta-se sobre a pertinência final do gesto da escrita em vista da realidade vivida, povoada pela diversa e estranha criatura a quem chamamos "gente". Diante da inexorável finitude da experiência, haveria mais verdade no que se escreve e perdura, ou no que se diz e fenece? Formalmente, os três poemas lançam mão das ferramentas conquistadas pelo verso livre e/ou polimétrico do poema modernista brasileiro, buscando aplicá-las ao léxico e à sintaxe coloquial contemporânea.

O artigo aborda o processo de aprendizagem da investigação no jornalismo, quando o repórter busca informações para construir uma notícia ou reportagem. O fazer jornalístico emprega diversos meios controversos para obter informações, atingindo de maneira anti-ética tanto camadas sociais mais marginalizadas quanto as mais poderosas. A partir de três situações etnográficas apresentadas para a reflexão (a palestra de uma jornalista consagrada; a aula de um “araponga”, detetive contratado por uma empresa jornalística; e, por fim, a palestra de um ex-“araponga”, agente do SNI, sobre etiqueta e marketing pessoal) serão discutidas as relações entre múltiplas agências sociais de investigação, incluindo o próprio ato de pesquisar o jornalismo.

Que gênero de grupo são as raças?
Authors: Bessone Magali , Silva Diana Mendes Machado
Published: December 2020

A questão do estatuto dos grupos racializados está no centro das discussões sobre os construtivismos: enquanto alguns argumentam que a existência socio-política de grupos racializados se refere a uma construção de coletivos realizada sob a influência de determinantes sociais (objetivismo), outros insistem em micro-processos subjetivos que levam a reivindicar ou negociar atribuições raciais. Nos dois casos, trata-se, primeiramente, de se opor a uma concepção essencialista de raça, segundo a qual todos os membros de um grupo racial herdam o mesmo conjunto de propriedades determinantes impossíveis de modificar, de perder ou de não transmitir. A posição essencialista, baseada em uma ontologia naturalista de raças, defende a ideia de um elevado grau de coesão social do grupo racial, fechado e homogêneo. Inversamente, as posições construtivistas devem levar em conta o estatuto de entidade coletiva do grupo racial construído, bem como sua função normativa em uma teoria da justiça social: trata-se então de abandonar tais categorizações para neutralizar seus efeitos ou de ajustá-los aos objetivos de justiça social que a consideração de tais entidades coletivas permite realizar? “Que tipo de grupo são as raças?” Essa é, pois, uma questão ontológica, cuja resposta é indispensável para resolver a questão normativa: “O que devemos fazer com os grupos racializados?”

Véu, nudez e o feminino na dança iraniana
Authors: Yunis Leandra
Published: December 2020

O presente artigo apresenta uma síntese histórica sobre a exposição do corpo feminino na dança persa e suas consequências para o desenvolvimento das artes do palco no Irã no século XX. Destaca-se o papel central do cinema e da literatura para o desenvolvimento da dança nacional iraniana, especialmente no que diz respeito à inspiração em obras clássicas, cujo princípio zoroastriano da equidade de gênero estabelece um contraponto à condição da mulher no direito familiar xiita. A importância desse estudo se deve ao fato de que a protagonização da mulher nas artes performáticas e dramatúrgicas iranianas, incluindo o cinema, se inicia pela dança e é em torno desta linguagem artística que se concentra a discussão moral sobre a exposição do corpo e a obrigatoriedade do véu.
Entre memória e ativismo político: contribuições de Nawal El Saadawi para o feminismo egípcio e transnacional
Authors: Luz Flávia Abud
Published: December 2020

Resenha comentada de “A Face oculta de Eva: as mulheres do mundo árabe” e “A Mulher com olhos de fogo – odespertar feminista” (publicações brasileiras, de 2002 e de 2019, respectivamente).
A partir de reflexões acerca da obra da ativista feminista egípcia Nawal El Saadawi e do desenvolvimento de discussões entre memória, trajetória e a busca das mulheres muçulmanas por direitos em Estados do Oriente Médio e Norte da África o texto visa apresentar as possibilidades e os desafios de problematizar a agência feminina com foco em questões como a normatização dos corpos femininos pelo viés da tradição, a discussão das leis de família, o acesso à educação, assim na intersecção entre gênero, cultura e religião que é uma característica da obra de Nawal El Saadawi.
Mulheres no mundo muçulmano e o ativismo para os direitos humanos
Authors: Luz Evelyn Faria da Silva
Published: December 2020

Os Direitos Humanos surgiram com caráter universal e generalista. Dessa forma, seus preceitos deveriam ser úteis para todos e todas. Todavia, no primeiro momento em que foi pensado – a partir de um ponto de vista masculinista – não foram incluídos direitos e demandas específicas das mulheres. Esse contexto foi mudado a partir do processo de especificação do sujeito de direito, que resultou em documentos voltados exclusivamente para elas, a partir do ativismo, incluía-se os Direitos Humanos das mulheres no cenário internacional. No entanto, o referencial criado foi criticado por feministas de fora do norte global por representar demasiadamente uma ótica branca e ocidental. Este artigo traz o caso específico das muçulmanas, apresentando como o ativismo delas se dá no sentido de trazer o instrumental de Direitos Humanos para sua realidade. Para tanto, nesse trabalho, abordam-se os desafios em geral enfrentados por esse grupo de mulheres e como estas agem. Destaca-se a importância dessas novas vozes, tanto no cenário internacional quanto no processo de internalização no âmbito local, para a maior eficácia e legitimidade dos Direitos Humanos.
gênese das hostilidades entre o Irã e os Estados Unidos.
Authors: Alves Tamires Maria
Published: December 2020

Este trabalho procura entender o que levou o Irã a passar de um papel de “aliado” ao de um “inimigo” dos Estados Unidos. Busca entender como as hostilidades que passaram a existir somente entre Irã e Estados Unidos foram produzidas como uma “ameaça” para toda “comunidade internacional”. O ponto de ruptura entre estas nações ocorreu, segundo a visão norte-americana, no ano de 1979 com a chamada Revolução Iraniana – e, por conseguinte, com o sequestro da embaixada americana no Irã-, em contrapartida o momento de ruptura desta relação na visão iraniana se deu em 1953 com o Golpe de Estado que depôs o primeiro-ministro Muhammad Mossadeq. Este trabalho tenta desnaturalizar essa imagem “ameaçadora” que o Irã tem na “comunidade internacional”, que, cria as condições de possibilidade para práticas violentas dirigidas a esse Estado. Para isso, será utilizada a teoria pós-colonial, uma vez que os autores pós-coloniais acreditam que a dominação econômica do Ocidente sobre o Oriente, viabilizada principalmente pelo colonialismo, foi capaz de abarcar também a dominação cultural destes povos.
Relações entre ciência, literatura e mundo da vida social: a problemática do progresso técnico a partir de algumas noções iniciais de Jürgen Habermas
Authors: Oliveira Raiany
Published: December 2020

Este texto faz uma breve leitura crítica do artigo Progresso técnico e mundo da vida social (1965) de Jürgen Habermas, buscando explicitar as ideias do autor acerca dos limites existentes entre os conceitos “ciência” e “literatura”, dentro do processo de construção de sua tese sobre a racionalidade comunicativa [kommunikative Vernunft], com o objetivo de fazer refletir algumas de suas ideias de modo a colaborar com as discussões dos problemas caros à historiografia da ciência e, mais amplamente, aos estudos sociais de ciência e tecnologia na contemporaneidade. O texto examina, também de forma breve, as principais referências utilizadas por Habermas em seu ensaio para tratar da cisão das chamadas ciências empírico-analíticas e das ciências histórico-hermenêuticas, principalmente ao longo da segunda metade do século XX.
Palavras-chave: História da Ciência, Progresso técnico e científico, Jürgen Habermas, Literatura, Modernidade.
Do Zero a Bovero: História e ativação dos arquivos referentes à Escola boveriana de Anatomia
Authors: Closs Jose Guilherme Veras , Miglino Maria Angelica , Liberti Edson Aparecido
Published: December 2020

A ativação de um arquivo prescinde o conhecimento da história das instituições que os produziram. Foi no sentido de capacitar os arquivos da Escola boveriana, ao trabalho de historiadores e demais pesquisadores, que desenvolvemos nossa pesquisa. Dessa maneira, pensando na trajetória dos atores e cenários referentes ao recorte proposto sob a luz das preocupações e métodos da arquivologia, pudemos dar os primeiros passos em direção ao pleno funcionamento dos serviços arquivísticos das instituições sede – Museu de Anatomia Humana do ICB-USP (MAH) e Departamento de Cirurgia da FMVZ- USP (VCI) – que guardam os vestígios materiais da Escola boveriana. É certo que ainda estamos apenas começando a ter contato com esse vasto conteúdo material, mas é possível afirmar que já existe o mínimo de tratamento e conhecimento processual arquivístico para dar suporte às pesquisas que pretendam utilizar os arquivos aqui trabalhados.
O Verbo Entoado: Uma breve reflexão sobre a palavra cantada e seus desdobramentos
Authors: Amaral Jorge Fernando Barbosa do
Published: December 2020

O artigo analisa a palavra cantada como um elemento que comporta, na sua essência, a música e a poesia, mas que, na verdade, é anterior a ambas, pois está na base do processo de manifestação dos sentimentos humanos. Para isso, o trabalho toma como base teórica tanto o pensamento de Jean-Jacques Rousseau (que defende a ideia de que apenas cantando o ser humano consegue, na sua plenitude, se manifestar emocionalmente), quanto o de Luiz Tatit (que encara a canção como uma cristalização dos recursos entoativos da fala). Como o artigo toma como base a palavra cantada no Ocidente, optou-se por um recorte histórico que teve a Idade Média como ponto de partida para as reflexões mais estritamente musicais.
Música de Mbira: Lentes e reflexões ampliadoras de conceito(s) e significado(s) da Música
Authors: Silambo Micas Orlando
Published: December 2020

Este trabalho apresenta, discute e propõe, através da Música de Mbira, uma abordagem integrativa como parte da compreensão aberta dos conceitos de músicas em suas dimensões socioculturais. Para isso, tomo como base uma pesquisa bibliográfica em torno dos estudos de (Etno)musicólogos, Antropólogos e afins, articulando com minha observação participante e prática na cultura musical africana. Os resultados apontam para uma  compreensão mais consolidada dos conceitos das Músicas abrangendo outros conhecimentos e saberes não sonoros que são estabelecidos, compartilhados e ressignificados musicalmente, culturalmente e socialmente dentro de um grupo específico inserido na sociedade. Reintero que os elementos sonoros não acontecem por si só, eles se articulam por inúmeras motivações e memórias  que nos direcionam para o seu papel como produto e processo social que esquematiza situações corriqueiras de uma rede mais ampla de relações humanas.
Perspectives on Beethoven’s Middle and Late Periods: Developments in his Writing for Cello in the Op. 69 and Op. 102 Sonatas
Authors: Pittenger Elise
Published: December 2020

This article explores the developments in Beethoven’s writing for the cello in the Op. 69 and Op. 102 sonatas, with the premise that they reflect the overall shift in his style from his Middle to Late Periods. In order to place the cello sonatas in context, the traditional framing of Beethoven’s work into three phases is described and well as the current state of cello writing at the turn of the century. The cello part in the Op. 69 sonata is then discussed, with attention to the role of the cello as compared to the piano and to the interaction between the two instruments. The Op. 102 sonatas are presented, also with attention to the interaction between the instruments. The suggestion is made that these sonatas illustrate Beethoven’s increasingly radical treatment of form, a treatment that results in challenging instrumental writing that, while not as gratifying as that of his Middle Period, nonetheless allows him to attain a new kind of expressivity as well as formal complexity.
