TOPLOTNA I MIKROSKOPSKA KARAKTERIZACIJA ŽARENIH FDM UZORAKA IZRAĐENIH OD PETG KOMPOZITA SA UGLJENIČNIM VLAKNIMA
Authors: Mićunović Miljana
Published: August 2020

U radu je korišćen komercijalno raspo­loživi FDM materijal, ColorFabb XT-CF20, od kojeg su delovi izrađeni na FFF štampaču, Prusa I3 Mk2, a zatim je primenjeno termičko postprocesiranje, tj. žarenje. Dve epruvete su izrađene 3D štampom, da bi potom jedna od njih bila podvrgnuta kontrolisanom procesu žarenja. Oba uzorka su zatim analizirana u pogledu toplotnih i mikro­skopskih karakteristika, u cilju posmatranja promena u temperaturi ostakljivanja (Tg), procentu kristaliničnosti i mezostrukturi poprečnog preseka, koje su rezultat prime­njenog žarenja. Rezultati pokazuju da žarenje može biti uspešno primenjeno na ovom materijalu, sa ciljem da se poboljšaju mehaničke karakteristike delova. Uočene mezo­strukturne promene pokazale su da proces hlađenja žarenih uzoraka zahteva primenu niže, konstantne brzine hlađenja u cilju minimizacije geometrijskog izobličenja.

Penatalaksanaan hepatitis C yang umum diberikan di Indonesia adalah terapi kombinasi Peg-IFNα dan RBV, namun terapi tersebut mempunyai efek samping seperti depresi, hipotiroidisme, memperlambat motorik, risiko kardiovaskular tinggi, dan lain sebagainya. Berdasarkan hal tersebut, maka dibutuhkan alternatif yang dapat meminimalisir efek samping yang ditimbulkan dalam penatalaksanaan hepatitis C, salah satunya menggunakan bahan herbal naringenin. Naringenin adalah flavanon alami yang diketahui memiliki efek hepatoprotektif sebagai anti-viral dan anti-fibrotik pada penatalaksanaan hepatitis C.  Metode penulisan yang digunakan dalam karya tulis ilmiah ini adalah metode kajian pustaka. Data yang digunakan berasal dari beberapa sumber literatur yang relevan dan sesuai dengan topik masalah yang dibahas. Naringenin berpotensi sebagai modalitas anti-viral dan anti-fibrotik pada penatalaksanaan hepatitis C. Sebagai anti-viral, naringenin mampu menghambat sekresi virus hepatitis C sebanyak 80% melalui penghambatan aktivitas MTP, ACAT2, dan HMGR. Sebagai anti-fibrotik, naringenin mampu menghambat jalur NF-kB dan TGF-β Smad3, tetapi naringenin memiliki bioavailabilitas dan solubilitas yang rendah, sehingga penyerapannya hanya sebesar 15%. Enkapsulasi naringenin dengan liposom dapat meningkatkan jumlah serapannya pada tubuh, meningkatkan waktu paruh, meningkatkan konsentrasi obat di plasma, serta mudah terkonsentrasi di hati.Kata kunci: hepatitis C, naringenin, liposom, anti-viral, anti-fibrotik

Socio-philosophical understanding of transformation of family in the dynamics of civilization over the period from Middle Ages to Modern Age
Authors: Blokhina Nataliia Viktorovna
Published: August 2020

Understanding of reasons and consequences of ongoing transformations with modern institution of the family is impossible without gaining insight into the processes, results and concept of changes that rook place with the family in its historically observable past. The subject of this research is the family and transformation of functions of the family in a historical context. The author conducts a socio-philosophical comparative analysis in compliance with the principle of systematicity and value of functions of the family through structural-comparative analysis of a historical type of medieval family with three ideal models of transitional historical periods from Middle Ages to Modern Age. The utopic concepts of T. More, T. Companella and F. Bacon served as the foundation for this research. Having examined the acceptable for philosophers types of family structure at various stages of the indicated historical period, the author determines dominant factors that affected the qualitative and essential changes of internal environment of the family as a small group, as well as structural-functional changes of the family as an institution, which led to transformation of the family and its functions. The author sees family as the basis of harmonious and happy life of an individual and a source of social well-being. The article is written from the perspective of familialism and viewed as a social institution. The scientific novelty lies in analysis of the historical type of family with hypothetical models of family, reflected in philosophical texts of this historical period, in order to determine the dominants that transform family, and establish the peculiarities of emergence of socio-philosophical concepts of studying institution of the family depending on social processes in the historical context of development. Such approach allow identifying the inward nature of structural relationships “individual – family – society – government” in a specific society.

Актуальность темы исследования. Большинство пролетных железобетонных конструкций испытывают повторяющиеся нагрузки различные по величине и знаку, то есть сложного напряженно-деформационного состояния. При этом расчету прочности, деформативности и трещиностойкости нормальных сечений исследователями уделяется значительно большее внимание, чем расчетам их приопорных участков, включая наклонные сечения, из-за его сложности и недостаточной изученности. Постановка проблемы. В процессе эксплуатации или в ходе боевых действий пролетные железобетонные конструкции испытывают значительные повреждения и существенное снижения несущей способности, особенно при действии малоцикловой повторной нагрузки. В связи с этим возникает необходимость восстановления их работоспособности и/или увеличения несущей способности. Анализ последних исследований и публикаций. В действующих нормах проектирования отсутствуют рекомендации по определению остаточной несущей способности таких конструкций и расчета их усиления. Известны способы восстановления работоспособности и усиления конструкции за счет увеличения сечения путем присоединения к ним дополнительных металлических или железобетонных элементов. Но методики расчета такого усиления также несовершенны. Выделение неисследованных частей общей проблемы. Восстановление работоспособности указанных конструкций предлагается осуществлять путем усиления растянутых их частей ФАП, а выполненные экспериментальные исследования лягут в основу совершенствования авторами деформационного метода расчета их несущей способности. Постановка задачи. Основной задачей является выявить особенности напряженно-деформированного состояния обычных однопролетных балок, испытанных на действие ступенчато возрастающей нагрузки до наступления предельного состояния или разрушения (серия I), малоцикловой знакопостояной (серия III), а также предварительно поврежденных и усиленных углепластиковыми обоймами (серия V) исследовательских элементов, доведенных до предельного состояния в предыдущих (серия III) экспериментах и сделать обобщенную оценку влияния указанного исследовательского фактора на их несущую способность. Изложение основного материала. Цель заключается в изучении влияния прочности (класса) бетона на прочность,
деформативность и трещиностойкость усиленных углепластиком пролетных железобетонных конструкций с учетом влияния других конструктивных факторов, величины и уровня повторной малоцикловой нагрузки высоких уровней с совершенствованием деформационного метода их расчета и разработкой аналогов расчетных моделей их утомительного силового сопротивления действующим нагрузкам и учетом физической нелинейности использованных материалов. Выводы в соответствии со статьей. Значения прогибов железобетонных образцов-балок больше зависят от величины относительного пролета среза.

Pyrrolotriazine 1 is an important precursor to Remdesivir, and an efficient synthesis is disclosed. This route features atom economy and reduced derivatization of starting materials, by making use of highly abundant, commoditized raw material inputs. The yield of triazine was doubled from 31% to 59%, and the synthetic step count was reduced from 4 to 2. A one-pot cascade sequence was developed for direct cyanation of pyrrole. Amination and cyclization with formamidine acetate complete the synthesis. The problematic nature of typically dilute electrophilic aminations was solved with semi-continuous processing. Moreover, development of a continuous platform afforded access to the ideal yet non-commercial aminating reagent, monochloramine. These efforts help to secure the Remdesivir supply chain.
Linkage Memory in Underivatized Protonated Carbohydrates

Published: August 2020

Carbohydrates are among the most complex class of biomolecules and even subtle variations in their structures are attributed to diverse biological function. Mass spectrometry has been essential for large scale glycomics and glycoproteomics studies, but the gas-phase structures and sometimes anomalous fragmentation properties of carbohydrates present longstanding challenges. Here we investigate the gas-phase properties of a panel of isomeric protonated disaccharides differing in their linkage configurations. Multiple conformations were evident for most of the structures based on their fragment ion abundances by tandem mass spectrometry, their ion mobilities in several gases, and their deuterium uptake kinetics by gas-phase hydrogen deuterium exchange. Most notably, we find that the properties of the Y-ion fragments are characteristically influenced by the precursor carbohydrate’s linkage configuration. This study reveals how protonated carbohydrate fragment ions can retain ‘linkage memory’ that provides structural insight into their intact precursor.

Organic diradicals are uncommon species that have been intensely studied for their unique properties and potential applicability in a diverse range of innovative fields. While there is a growing class of stable and well characterized organic diradicals, there has been recent focus on how diradical character can be controlled or modulated with external stimuli. Here we demonstrate that a diiron complex bridged by the doubly oxidized ligand tetrathiafulvalene-2,3,6,7-tetrathiolate (TTFtt2−) undergoes a thermally induced Fe-centered spin-crossover which yields significant diradical character on TTFtt2−. UV-vis-Near-IR, Mössbauer, NMR, and EPR spectroscopies with magnetometry, crystallography, and advanced theoretical treatments suggest that this diradical character arises from a shrinking TTFtt2− π-manifold from the Fe(II)-centered spin-crossover. The TTFtt2− centered diradical is predicted to have a singlet ground state by theory and variable temperature EPR. This unusual phenomenon demonstrates that inorganic spin transitions can be used to modulate organic diradical character.
Ultrafast Pump-Probe Spectroscopy of Finite-Sized Neutral Iron Oxide Clusters
Authors: Garcia Jacob , shaffer ryan , Sayres Scott
Published: August 2020

Neutral iron oxide clusters (FenOm, n,m ≤ 16) are produced in a laser vaporization source using O2gas seeded in He. The neutral clusters are ionized with a sequence of femtosecond laser pulses and detected using time-of-flight mass spectrometry. Small clusters are confirmed to be most prominant in the stoichiometric (n = m) distribution, with m = n + 1 clusters observed above n = 4. Pump-probe spectroscopy is employed to study the dynamics of an electron transfer from an oxygen orbital to an iron nonbonding orbital of iron oxide clusters that is driven by absorption of a 400 nm photon. A bifurcation of the initial wavepacket occurs, where a femtosecond component is attributed to electron relaxation assisted through internuclear vibrational relaxation, and a slow relaxation shows the formation of a bound excited state. The lifetime and relative ratio of the two pathways depends on both the cluster size and iron oxidation state. The femtosecond lifetime decreases with increased cluster size until a saturation timescale is achieved at n > 5. The relative population of the long-lived excited state decreases with cluster size and suggests that the excited electron remains on the Fe atom for > 20 ps.
The Earth Mover’s Distance as a Metric for the Space of Inorganic Compositions
Authors: Hargreaves Cameron , Dyer Matthew , Gaultois Michael , Kurlin Vitaliy , Rosseinsky Matthew J
Published: August 2020

It is a core problem in any field to reliably tell how close two objects are to being the same, and once this relation has been established we can use this information to precisely quantify potential relationships, both analytically and with machine learning (ML). For inorganic solids, the chemical composition is a fundamental descriptor, which can be represented by assigning the ratio of each element in the material to a vector. These vectors are a convenient mathematical data structure for measuring similarity, but unfortunately, the standard metric (the Euclidean distance) gives little to no variance in the resultant distances between chemically dissimilar compositions. We present the Earth Mover’s Distance (EMD) for inorganic compositions, a well-defined metric which enables the measure of chemical similarity in an explainable fashion. We compute the EMD between two compositions from the ratio of each of the elements and the absolute distance between the elements on the modified Pettifor scale. This simple metric shows clear strength at distinguishing compounds and is efficient to compute in practice. The resultant distances have greater alignment with chemical understanding than the Euclidean distance, which is demonstrated on the binary compositions of the Inorganic Crystal Structure Database (ICSD). The EMD is a reliable numeric measure of chemical similarity that can be incorporated into automated workflows for a range of ML techniques. We have found that with no supervision the use of this metric gives a distinct partitioning of binary compounds into clear trends and families of chemical property, with future applications for nearest neighbor search queries in chemical database retrieval systems and supervised ML techniques.

Symmetric, Robust, and High-voltage Organic Redox Flow Battery Model Based on a Helical Carbenium Ion Electrolyte
Authors: Moutet Jules , Veleta Jose M , Gianetti thomas
Published: August 2020

Redox flow batteries (RFBs) represent a promising technology for grid-scale integration of renewable energy. Redox-active molecular pairs with large potential windows have been identified as key components of these systems. However, cross-contamination problems encountered by the use of different catholyte and anolyte species still limits the development of reliable organic RFBs. Herein, we report the first use of a helical carbenium ion, with three stable oxidation states, as electrolyte for the development of symmetric cells. Cyclic voltammo-amperometric studies were conducted in acetonitrile to assess the essential kinetic properties for flow battery performance and cycling stability of this molecule. The selected [4]helicenium ion was then evaluated by using mono- and bi-electronic cycling experiments, resulting in 745 and 80 cycles respectively, with near-perfect capacity retention. This helical carbenium ion based electrolyte achieved a proof-of-principle 2.12 V open circuit potential as an all-organic symmetric RFB.
Long-range Stacking Effects of Nucleobases in Charge Transfer
Authors: Li Zhongwei , Han Keli
Published: August 2020

Base-stacked structure is an important feature of DNA molecules. Previous studies on the stacking effect concerning DNA-mediated hole transfer have revealed the influence of neighboring bases on onsite energies. But the neighboring base effect acts only in a short-distance. Besides it, a long-range (longer than three base pairs) stacking effect called squeezing effect in this paper has not yet been reported. Such a squeezing effect causes the bases near the middle of a sequence consisting of same type base pairs have lower onsite energies than the bases near the terminals. We predict it by H ̈uckelanalysis in an unconventional way and confirmed it by semiempirical calculations combinated with molecular dynamics simulations. The results suggest that in order to obtain a reasonable onsite energy map when study charge transfer on DNA, the stacking effects should be considered in a long-distance as possible. The consideration of squeezing effect also provides a new suggestion on the driving force of fluctuation-assisted DNA charge transfer. The method used to calculate the onsite energies in abase stack can be generalized to other π-stacked systems.

Published: August 2020

COVID-19, a disease caused by SARS-Cov-2 virus, has become pandemic and is spreading widely across the world, and resulted in deaths of millions in just few months. Statistically, it is noted that worldwide deaths has occurred due to outbreak of infectious diseases. There is list of epidemics caused by infectious diseases like Ebola, Severe Acute Respiratory Syndrome (SARS), swine flu, bird flu, etc. But, spread of COVID-19 is much more remarkable in very short period of time. Modern system of medicine, do not have any definitive management. Now, we need to think about other systems of medicine to break this chain. So in Ayurvedic perspective, the COVID-19 can be considered as Aupasargika/ AgantujaVyadhi (Infectious disease). Present study aims to understand the principles of Ayurveda, in view of concept, epidemiology, etiopathology, prognosis, prevention and management of infectious diseases. It comprises of probable approaches of infectious diseases through Ayurveda. References established on data pertaining to available in Ayurveda classics, modern texts, peer review journals regarding the same. The speedily spread of COVID-19 is due to indulgence in the etiological factors, by people of this era. The onset period of this pandemic wasVasantaRutu(spring), hence KaphaPrakopa(vitiation of Kapha) is there. And the further pathogenesis is like ShwasanakaSannipatikaJwara(fever due to vitiation of all humors). So, Panchakarma (Internal purification), Rasayana Chikitsa (Rejuvenating treatment) and Sadvritta (Good regime) can be included in the management of such diseases. From this study it can be concluded that disease is produced due to an imbalance between physical and mental elements, as it reduces resistance of body against disease. If we cure or prevent this imbalance and the strengthen host's defense system by Ayurvedic drugs, lifestyle modifications, and diet modifications, the body will be immune to diseases.

En su propuesta Isaac Newton considera que se puede hablar de dos tipos de puntos: los puntos sin dimensiones y aquellos que surgen del movimiento y que pueden tener alguna clase de medida/magnitud/métrica, es gracias a la existencia de estos últimos que Newton puede realizar el cálculo de la fluxión aun cuando al final del procedimiento, vuelva a considerarlo como un punto sin dimensiones. Una vez expuesta la propuesta de Newton sobre las fluxiones, presentaré la crítica de Berkeley a diversos elementos tanto conceptuales como metodológicos del trabajo de su predecesor, Finalmente ofreceré algunas conclusiones acerca de la validez de las críticas del obispo de Cloyne a Newton.

Contenido de nitrógeno y fibra cruda, en tres periodos de rebrote de erythrina sp. establecidos como bancos de proteína, en Satipo
Authors: Bazán Alonso Luis Enríque , Gavilán A. Liliana , Chávez Y. Kely , Sánchez P. Williams
Published: August 2020

El estudio se realizó en la provincia de Satipo para determinar la producción y relación entre los contenidos de nitrógeno y fibra cruda, con tres periodos de rebrote pos poda, en la erythrina sp., establecidas como bancos de proteína. Se utilizó un área de 360 m2 de un banco de erythrina sp. establecido en un año de anterioridad. La variable independiente fue: Período de rebrote, a 30 días de rebrote, 60 días de rebrote y 90 días de rebrote, para el cual se realizó la poda de uniformización a una altura de 100 cm, que fue considerada como el día cero de rebrote.

Las variables dependientes fueron: rendimiento de forraje verde por planta (g), rendimiento de materia seca por planta (g), contenido de proteína (%) y contenido de fibra cruda (%). Las variables proteína y fibra cruda fueron evaluados en el Laboratorio de Nutrición Animal de la Facultad de Zootecnia - UNCP. Se usó estadística descriptiva (promedios y desviación estándar). La producción de forraje verde y materia seca aumenta a medida que se incrementa el periodo de rebrote. El contenido de fibra cruda se incrementa a medida que se incrementa el periodo de rebrote, mientras la proteína encuentra un máximo valor a los 60 días de rebrote, luego del cual decrece. Por tanto, a medida que se incrementan los días del periodo de rebrote, el contenido de fibra cruda se incrementa y el contenido de nitrógeno disminuye
The Covid-19 pandemic
Authors: Duncan Grant
Published: August 2020

This introductory article traverses the basic events since the outbreak of Covid-19 in China in December 2019, through its arrival in New Zealand and the nationwide lockdown and collective effort to eliminate it, up until the end of May 2020. The government acted decisively, with considerable public support and cooperation, and the overall response was therefore a success, albeit a very costly one.
Alone Together
Authors: Walker Holly
Published: August 2020

Even prior to Covid-19, loneliness posed a significant public policy challenge. Loneliness intersects with other wellbeing factors, so prioritising wellbeing requires policies that allow social interaction to thrive. Prolonged loneliness also creates significant public health risks. Covid-19 thrust loneliness into greater prominence with enforced social isolation compounded by considerable employment and income loss. The level 4 lockdown contributed to an increase in self-reported loneliness, especially among those already at risk. Future analysis will determine the full impact of Covid-19 on loneliness; in the meantime, policy to enable social interactions to thrive will be an important part of the recovery.
Doubling Down on Children and Young People’s Aspirations Post-lockdown
Authors: Provoost Donna , Bruce Katie
Published: August 2020

Children and young people experienced the Covid-19 lockdown differently from adults, and we need to consider these impacts as part of the recovery measures. Prior to Covid-19, cracks in our social system were already evident. At that time, children and young people told us what they wanted in order to create better future. The aspirations they shared are even more relevant post-Covid-19. Their views shaped the Child and Youth Wellbeing Strategy, and our best approach to supporting child wellbeing as part of the recovery is to double down on implementing this strategy. This will ensure that the recovery response is child-centred, holistic and aspirational.
Why the Commerce Act 1986 is Unfit for Purpose
Authors: Bertram Geoff
Published: August 2020

New Zealand’s Commerce Act 1986 overturned both common law consumer protections and previous legislation that had spelled out procedures for identifying and sanctioning the abuse of market power. Inspired by Chicago School doctrines and an anti-state philosophy, the legislation opened the way for three decades of monopoly profiteering, exploitation of the weakest consumer groups and anti-competitive conduct, while regulation has been absent or ineffective. In this article, key weaknesses in the 1986 legislation are examined, and some remedies suggested.

Digitally-Controlled Bondwire Inductor with High Quality Factor and Wide Tuning Range
Authors: Lee Yonggoo , Lee Bomson
Published: August 2020

A tunable bondwire inductor (TBI) with high-quality factor and wide tuning range is presented. The proposed TBI is fabricated on a single chip by combining a single-pole four-throw (SP4T) switch integrated circuit (IC) and four bondwire inductors on a package substrate. The SP4T switch IC is fabricated using 180 nm silicon-on-insulator (SOI) complementary metal-oxide-semiconductor (CMOS) technology. The fabricated TBI chip exhibits a 521% tuning range of inductance from 1.77 to 11 nH at 0.1 GHz and a relatively high-quality factor. To the knowledge of the authors, the results of this work demonstrate the best combined performance of inductance tuning range and quality factor.
A Disarray Around the Theme of Lesson Planning: Definition and Characterization of its Constituent Elements
Authors: Alves Milena , Bego Amadeu Moura
Published: August 2020

This paper aims to investigate the different meanings that the constituent elements of lesson planning have assumed in the works of Science Education and proposes, from a critical approach, the delimitation of its essential constituent elements, as well as their definitions. To this end, a systematic literature review was performed, involving the analysis of 403 papers from: Science Education journals in strata A1 and A2; Proceedings of Teaching and Education meetings; and theses and dissertations from the CAPES catalog. Studies were selected from 2012 to 2016. An absence of terminological equivalence was found for the terms strategy, methodology, method, technique, and resource. In addition, most of the papers use these terms unlinked from their definitions and any theoretical frameworks. Subsequently, theoretically grounded definitions were proposed for each of the terms in the context of lesson planning. It is argued that the methodological approach guides the teaching and learning process and consists of an essential element of lesson planning, which involves explaining the background conceptions about teaching and learning, the nature of science, and the social role of school education. Therefore, planning a lesson needs to be an explicit and conscious act of the teacher, in which he becomes aware of the methodological approach to be adopted. This approach will guide the requirement for the delimitation of learning objectives, the selection and arrangement of instructional and assessment strategies, as well as the teaching resources and instructional materials.

NUTRITIONAL HEALTH STATUS WITH DIFFERENT ASPECT OF TARGET GROUP (PREGNANT AND LACTATING WOMEN): A LITERATURE REVIEW
Authors: Singh Dhakad Rajeev , Kumar Abhishek
Published: August 2020

The pregnant women and lactating women are considered as the nutritionally exposed group specifically in the emerging countries. The present paper is mainly focusing on nutritional intake status/behaviours with respect to the culture, beliefs, habits, socioeconomic status and the knowledge and awareness of the target group i.e. pregnant and lactating women. Method: we were review various literature and studies with the keywords such as nutrition, dietary intake, food intake behaviour, culture and practices. In this paper literature were divided it into three sections. These were (a) Nutrient and Dietary Intake; (b) Cultural Beliefs and Practices; (c) Socio-Economic Characteristics. Results: Nutrient and dietary intake were not matched with recommended RDA. Cultures beliefs and practices were very changed in the different community and economic groups such as tribal community were not taking important food during pregnancy and lactation period and Urban women had the higher knowledge of nutrition diet compared to rural women. Socio-economic condition influences the dietary behavior or food’s choice of pregnant and lactating women. Conclusions: Various studies and papers were reviews in this paper, we found gaps between recommended RDA, nutritional behavior, and practices in the target groups of developing countries such as India. This paper concludes the further research and intervention are required on pregnant and lactating women on nutritional behaviour as well as dietary practices.

Sobre o lugar de fala: Localizações, silenciamentos e autorizações
Authors: Mendonça Camila , Albuquerque Cíntia
Published: August 2020

Publicado em 2017, a obra de Djamila Ribeiro tem sua centralidade no conceito de “lugar de fala”, bastante citado nos últimos anos, especialmente em debates pela internet. Erroneamente confundido com representatividade, não diz respeito a quem pode ou não falar sobre quais assuntos, mas quais localizações sociais autorizam ou desautorizam à voz, promovendo, assim, a propagação ou o silenciamento de conhecimentos. Pela perspectiva do feminismo negro, a autora aponta a necessidade de pensar outros saberes para além das epistemologias hegemônicas, sendo a identidade um marcador fundamental para lembrar da inexistência de discursos neutros e universais, construídos nas relações de poder.Palavras-chave: Djamila Ribeiro; lugar de fala; feminismo negro; identidade; poder;
Como capturar uma world music em circulação?
Authors: Campos Lúcia
Published: August 2020

A partir das ações e negociações presentes na instalação de uma cena de música amplificada, busco apreender o que se entende por “músicas do mundo” ou “world music” em festivais da Europa. Abordo a globalização como um fenômeno situado a partir da etnografia da circulação do grupo Siba e a Fuloresta por dois festivais europeus. Discuto o palco como lugar de legitimação de práticas culturais diversas como “música” e as representações construídas nas relações entre programadores, artistas e público em torno da ideia de “diversidade”, investigando especialmente a fabricação de imaginários de Brasil nesse circuito.
A escuta opositora de canções brasileiras: Negociando sentidos entre performances e versões
Authors: Furtado Lucianna , Guimarães Corrêa Laura
Published: August 2020

A partir do conceito de olhar opositor de bell hooks e de leitura negociada em Stuart Hall, este artigo reflete sobre versões de canções brasileiras em que as ouvintes e intérpretes subvertem sentidos ao contestar discursos, masculinos em sua maioria, marcados pelo sexismo, pela heteronormatividade, pelo racismo, pelo classismo, entre outras formas de opressão, presentes na música popular; discutindo, especialmente, o samba. Compreendendo o samba como forma afro-brasileira marcada por histórias de resistência, as versões contestadoras que destacamos não pretendem anular a versão de base, mas propõem uma negociação – política, musical – com os sentidos dominantes ou preferenciais.
