Authors: Sedelnikova L.L.
Published: May 2019

As a result, the study using the method of x-ray fluorescence analysis with synchrotron radiation (SRX RF), for the first time obtained reliable data on the content of 20 elements in the above-ground (leaves) and underground (rhizome) plant organs Hemerocallis hybrida (sort Regal Air) growing in an urban environment in the Novosibirsk oblast. It is shown that the maximum concentration of most elements falls on the organs of plants that live in a man-made environment. The high content of heavy metals – lead, zinc, iron, manganese, copper – in the leaves was noted. The increased concentration of chemical elements in the organs of plants Hemerocallis hybrida, which suggests that they are bioindicators of the ecological state of industrial transport zones.
evaluación de los académicos a debate: comentarios desde la sociología de la ciencia. Apuntes para un análisis integrado
Authors: Pérez Chavarría Eduardo
Published: May 2019

Este ensayo tiene como finalidad realizar un comentario crítico al libro La evaluación de los académicos. Instituciones y Sistema Nacional de Investigadores, aciertos y controversias, coordinado por Giovanna Valenti y Graciela Bensusán, publicado en 2018 por la Flacso-México. El objetivo consiste en presentar apuntes para un análisis integrado (teórico-empírico) de la problemática abordada por las autoras y sus hallazgos. Se busca hacer una contribución al debate teórico desde la perspectiva de la sociología de la ciencia, que permita vincular los hallazgos empíricos encontrados sobre los modelos de evaluación a las discusiones contemporáneas de la sociología de la ciencia, especialmente a aquellas que tratan sobre la dimensión política y la constitución de una práctica evaluativa global y sistémica, anclada en mecanismos digitales y analógicos. Si bien cabe mencionar que este no fue nunca el objetivo del trabajo, una reflexión en este sentido resulta indispensable dada la temática del libro.
Optimization of grain quality parameters for winter rye breeding
Authors: Ponomareva M. L. , Ponomarev S. N.
Published: May 2019

The purpose of this work was to evaluate the phenotypic variability of grain quality indicators and to identify the set of the most informative indicators for the selection of different use varieties of winter rye. The research was carried out in Tatar Scientific Research Institute of Agriculture – Subdivision of the “Kazan Scientific Center of Russian Academy of Sciences” in 2001–2015 on 15 varieties of winter rye. Twenty parameters defining quality of grain and raw value were estimated: technological indicators (thousand grain mass, full-scale weight and grain uniformity), parameters preharvest sprouting (falling number, rate of amylogram, temperature of peak of starch gelatinization), kinematic water extract viscosity (WEV) of grain meal, baking properties (organoleptic assessment of trial baking bread). The greatest influence of genotype was found on WEV (34.8 %) and protein content (27.8 %). These features should be primarily the subject of phenotypic evaluation in the breeding process. Phenotypic variability of criteria of carbohydrate-amylase complex, α-amylases activity and technological parameters was determined predominantly (68.6…82.5 %) by environmental factors. There was no significant relationship between falling number and protein content. The falling number correlated with the rate of amylogram and the temperature of gelatinization. Positive conjugation of the average power of WEV with the rate of amylogram and falling number was found. On the basis of a prolonged phenotypic evaluation using principal component analysis we have optimized the analyzed indicators of quality properties of winter rye grain. For breeding evaluation of winter rye it is proposed to use four integral indi cators having the greatest weight load: protein content, falling number, water extract viscosity and thousand grain mass. This complex of features will provide objectivity and completeness of the evaluation of the breeding material. It was shown that the kinematic viscosity of the water extract should become an important selection index, both for determining the baking qualities of rye, and for revealing the fodder grain advantages.

Background: Identifying biomarkers for cells harboring replication-competent HIV is a major research priority. Recently, there have been mixed reports addressing the possibility that CD32-expressing T-cells are enriched for HIV. There is growing evidence that CD32 expression increases with cellular activation that may be related to, but not necessarily specific for, infection with HIV.  However, the relationship of CD32 expression to HIV-infection in subtypes of tissue-resident leukocytes is unclear.  Methods: First, we used duplex chromogenic in situ hybridization to identify cells actively transcribing RNA for both CD32 and HIV on human gut tissues. Then we performed multiplexed immunofluorescence and in situ hybridization (mIFISH) on sections from the same tissues to determine the phenotype of individual cells co-expressing HIV-RNA and CD32-RNA.  Results: HIV-RNA+ cells were more abundant in tissues from viremic individuals compared to those on suppressive anti-retroviral therapy (ART). However, staining by both methods indicated that a higher proportion of HIV-RNA+ cells co-expressed CD32-RNA in ART-suppressed compared to viremic individuals. The majority of HIV-RNA+ cells were CD3+.Conclusions: Our data suggest that the transcription of CD32-RNA is correlated with HIV transcriptional activity in CD3+ cells found within human gut tissue. Whether or not up-regulation of CD32-RNA is a direct result of HIV reactivation or more global T cell activation remains unclear.

Photosynthetic Function and the Photoprotective Mechanism of Leaves of Morus alba L. Seedlings under NaCl and NaHCO3 Stress Revealed by Proteomics
Authors: Zhang Huihui , Xu Nan , Li Xin , Sun Guangyu , Shi Guangliang
Published: May 2019

Photosynthetic function, photoprotection, and the response of related proteomics of mulberry (Morus alba L.) seedling leaves under NaCl and NaHCO3 stress with the same Na+ concentration (100 mmol•L-1) were studied by using photosynthetic gas exchange and chlorophyll fluorescence techniques combined with TMT proteomics. The results showed that NaCl stress had no significant effect on photosystem II (PSII) activity in mulberry seedling leaves, and the expressions of the related proteins, OEE3-1 and PPD4, of the PSII oxygen-evolving complex (OEC) and the antenna proteins, CP24 10A, CP26, and CP29, of LHCII in the leaves also increased to varying degrees. The photosystem I (PSI) activity in the leaves of mulberry seedling also increased, and the expressions of some proteins, PsaF, PsaG, PsaH, PsaL, PsaN, and Ycf4, in PSI increased significantly under NaCl stress. Under NaHCO3 stress, the activity of PSII and PSI and the expression of their protein complexes and the electron transfer-related proteins significantly decreased. NaCl stress had little effect on RuBP regeneration during dark reaction in the leaves and the expressions of glucose synthesis related proteins and net photosynthetic rate (Pn) did not decrease significantly. The leaves could adapt to NaCl stress by reducing stomatal conductance (Gs) to increase water use efficiency (WUE). Under NaHCO3 stress, the expression of dark reaction-related proteins was mostly down-regulated, and Gs was significantly reduced, which indicated that non-stomatal factors were important reasons for the significant inhibition of carbon assimilation. In the photoprotective mechanism under NaCl stress, the expression of cyclic electron flow (CEF) related proteins, ndhH, ndhI, ndhK, and ndhM, involved in NAD(P)H dehydrogenase (NDH) and the key enzyme of the xanthophyll cycle, violaxanthin de-epoxidase (VDE) were up-regulated. In addition, the ratio of xanthophyll cycle components (A+Z)/(V+A+Z) was increased. The expressions of proteins FTR and Fd-NiR, which are related to Fd-dependent ROS metabolism and nitrogen metabolism, were also significant up-regulated under NaCl stress, which can effectively reduce the electronic pressure on Fd. Under NaHCO3 stress, the expressions of CEF-related proteins, VDE, ZE, FTR, Fd-NiR, Fd-GOGAT, SGAT, and GGAT, were significant down-regulated, and the photoprotective mechanism, like the xanthophyll cycle, CEF, and photorespiration, might be damaged, resulting in the inhibition of PSII activity and carbon assimilation in leaves of mulberry seedling under NaHCO3 stress.
An Empirical Oil, Steam, and Produced-Water Forecasting Model for Steam-Assisted Gravity Drainage With Linear Steam-Chamber Geometry
Authors: Dixon David , Nguyen Anthony
Published: May 2019

Presented here is a steam–assisted–gravity–drainage (SAGD) forecasting technique for oil and water production and steam injection based on linear steam–chamber geometry and an empirical form for the progression of the steam/oil interface with time. The oil forecast model generates full–cycle SAGD production profiles using three empirical inputs (the initial plateau oil rate qo,si, an exponent n, and the rising–phase–chamber angle θ) and volumetric parameters (well length, pay thickness, porosity, half–well spacing, and initial and residual oil saturation). Steam and produced–water forecasts are derived analytically using the resulting steam–chamber geometry and the heat required for the fluids, rock, and overburden.

Peak rate is a direct input in this methodology, and as a result only volumetric and some thermodynamic parameters are required, but not fluid or transmissibility inputs, such as viscosity and permeability. This allows for direct use of commercial SAGD production data in the forecasting process. The model predictions are validated at a high level with field data from Devon Canada Corporation's Jackfish SAGD project and numerical simulation.
Hybrid spectral speed determination method for rotary machines
Authors: Gárdonyi Gábor , Samu Krisztián
Published: May 2019

Accurate rotational speed determination for rotary machines tends to be allocated high priority in technical applications. In some cases, it is not easy to measure shaft speed directly. Vibration diagnostic tools can offer an alternative solution to the problem posed by direct rotational speed measurement. Using calculated spectra and cepstra can help to determine the rotational speed easily and accurately. This paper examines the comparison of the spectrum and cepstrum based methods in terms of their applicable ranges and rotational speed estimation accuracy. Most papers which present similar comparisons state that the speed of rotary machines can be determined better with cepstrum calculation. However, this argument does not entirely stand up to scrutiny. This paper explains how to calculate the possible speed estimation error which arises out of the resolution of the discrete output data produced by the methodologies. The novel hybrid speed estimation logic uses these equations to decide which method results in the most accurate output. Numerous vibration measurements were made to test the usability of this hybrid method. It was successfully tested on electromotive drive trains, as well as spark- and compression-ignition internal combustion engines with different cylinder numbers and arrangements.

Authors: Li Ying , Wang Jindong , Zhao Haiyang , Zhang Longyu , Ou Lingfei
Published: May 2019

According to the nonlinearity and nonstationarity characteristics of reciprocating compressor vibration signal, a fault feature extraction method of reciprocating compressor based on the empirical wavelet transform (EWT) and state-adaptive morphological filtering (SMF) is proposed. Firstly, an adaptive empirical wavelet transform was used to divide the Fourier spectrum by constructing a scale-space curve, and an appropriate orthogonal wavelet filter bank was constructed to extract the AM-FM component with a tightly-supported Fourier spectrum. Then according to the impact characteristic of the reciprocating compressor vibration signal, the morphological structural elements were constructed with the characteristics of the signal to perform state-adaptive morphological filtering on the partitioned modal functions. Finally, the MF-DFA method of the modal function was quantitatively analyzed and the fault identification was performed. By analyzing the experimental data, it can be shown that the method can effectively identify the fault type of reciprocating compressor valve.
Effect of heat transfer optimization on brake noise characteristics of automotive disc brake
Authors: Zhang Sen , Zhang Jian
Published: May 2019

Heat effect is one of the most important factors affecting the brake noise level. The finite element model for transient heat transfer analysis of disc brake is established based on heat transfer control equation and heat dissipation boundary conditions of dynamic convection. According to the NVH test and modal calculation, the brake noise characteristics are tested and analyzed. Meanwhile, the heat transfer simulation is verified and shows high accuracy. The discrete data for the response surface function are obtained by the Central Composite Design method with the peak temperature and mass as the target variables. The error of regression function is judged by fitting decision coefficient, correcting decision coefficient and root mean square error. By the optimizing mathematical model, the brake disc temperature peak can be greatly reduced and the heat transfer ability is obviously optimized without mass increasing, the time with temperature above 120 °C can be reduced by 46 %. Through the comparison of brake noise level before and after optimization, it can be known that the noise level can be significantly decreased after structural optimization, except the first order resonance frequency. The optimization result has good social and economic value.

Published: May 2019

The proposed research involves the design and implementation of a novel hybrid topology for power quality improvement using multilevel inverter fed induction motor by reducing vibration for Textile applications. Various modern applications have started to require higher power gadgets as of late. Staggered inverter is equipped for giving wanted substituting voltage level at output utilizing different low-level DC voltage as an input. In H-connect staggered inverter, the quantity of output level is characterized by the quantity of exchanged capacitor cells. A small amount of voltage can be utilized to produce a supported output voltage by exchanging the capacitor in parallel and in series. Staggered inverter produces less Total Harmonic Distortion (THD), less electromagnetic interference and less voltage inrush on switches. The proposed topology delivers a staircase waveform with higher number of output level utilizing less segments contrasted with a few existing exchanged capacitor multilevel inverter. The task manages cascaded H-connect staggered inverter that can be utilized for both single and three stage change. The structure is created with H-bridge inverter including DC-DC converter. A sine pulse width twist is decided on PWM pulses. The inverter essentially takes care of the issue of capacitor voltage adjusting as every capacitor is charged to the esteem equivalent to one of the information voltages at each cycle. Recreation is finished with the assistance of MATLAB Simulink programming and the exploratory outcomes for current and voltage at various THD esteems are appeared and the equivalent is done for equipment. The prototype structure is conceded and analysed for various parameters of proposed method, which results in reduced switches and proves more efficient than other conventional methods and in addition it is more proficient for pumping process in textile industry for wastewater treatment.
Consistency in efficiency benchmarking: urban water utility regulation with performance improvement
Authors: Gidion Dickson K. , Hong Jin , Hou Bojun , Shillamkwese Samson S. , Adams Magdalene Z. A. , Khoveyni Mohammad
Published: May 2019

For more than 20 years, urban water utility (UWU) regulators have been using key performance indicators to monitor water supply services. In many circumstances, the empirical methods used to rank UWU performance are different between regulators of different countries, although the benchmarking basics are the same. The diversity of benchmarking methods limits the sharing of management strategies between countries. Using data envelopment analysis (DEA), this paper presents a consistency analysis of the performance score method used by the Energy and Water Utilities Regulatory Authorities of Tanzania. DEA is appropriate for this purpose because of its demonstrated flexibility in applications with diverse production environments. Thus, this paper proposes methods for benchmarking strategies to assess UWU efficiency- and management-specific goals within and between countries. The assessment shows that network DEA (NDEA) outperforms empirical methods; regulators using the proposed NDEA technique will benchmark UWU efficiency under a yardstick competition regime and, at the same time, identify the most efficient and weak UWUs using pure variable values. This innovation monitors UWU performance progress and promotes sharing of quality management strategies between UWUs and countries.

Microwave Facilitated Green Synthesis and Characterization of Acrylamide Grafted Copolymer of Kheri (Acacia chundra) Gum Polysaccharide
Authors: Malviya Rishabha , Sharma Pramod Kumar , Dubey Susheel Kumar
Published: May 2019

Objective:

In the present study, an attempt was made to synthesize biodegradable, hemocompatible,
antimicrobial and pH-responsive hydrogel.

Methods:

Microwave facilitated green synthesis was carried out for the grafting of acrylamide over
Kheri Gum Polysaccharide (KGP) backbone. The grafted hydrogel was characterized in terms of
FTIR spectra, 1H NMR spectra, SEM image, contact angle, chemical resistant, biodegradation, blood
clotting time, thrombogenicity, hemolytic activity and cytotoxic effect.

Results:

More swelling was observed by graft copolymers (KGP-g-Am) in all the solvent systems
such as double distilled water, 1 N NaOH and 0.1 N HCl than KGP. Graft copolymers showed more
swelling in 1 N NaOH than in 0.1 N HCl, followed by distilled water. Blood clotting studies showed
longer clotting time for KGP-g-Am as compared to the uncoated glass surface and KGP coated glass
surface. Results obtained after molecular docking predict that TLR-4 receptors are considerably
more liable than TLR-2 receptors for antimicrobial activity of both KGP-g-Am and KGP. Experimental
data evidently explains the better antimicrobial efficacy of KGP-g-Am (K1) against Escherichia
coli and Aspergillus niger than KGP. In molecular docking studies, KGP-g-Am showed prominent
anticancer activity than KGP at the protease-activated receptor (PAR1). Results of in vitro cytotoxic
activity against breast cancer cell lines (MCF 7) predict better control over cell growth by
KGP-g-Am (K1) as compared to KGP.

Conclusion:

It can be elicited from the data that microwave assisted grafting over KGP backbone
modulates and introduces prerequisite properties within the polymer and can be utilized for various
biomedical, pharmaceutical and cosmeceutical applications.
Microwave-assisted Synthesis of Water-soluble Fluorescent Carbon Nanoparticles as an Effective Crosslinker to Control the Water Absorption and Moisture Transmission Behavior of Chitosan/Carbon Nanocomposite Film
Authors: Bajpai S.K. , Kandra R. , Namdeo M.
Published: May 2019

Background:

Carbon dots are a new class of biomaterials that have found a wide range of biomedical
applications like cell imaging, targeted delivery, and bio-sensing. A review of the literature reveals
that there are fewer reports on nanocomposites prepared by entrapment of carbon dots into polymers.

Objective:

A tetra carboxylic acid compound, can conveniently be used as a precursor to synthesize
negatively charged carbon dots.

Methods:

Carbon dots have been prepared by microwave induced treatment of BTCA so as to have
carboxylic groups onto the surface of the carbon dots. Their size distribution was determined by TEM
analysis. These CNPs are loaded into chitosan films by solvent casting approach. The water absorption
behavior of chitosan/carbon dots nanocomposite films is investigated by gravimetric method.

Results:

The size of the CNPs was found to be in the range of 50 to 60 nm with almost spherical geometry.
Their zeta potential was found to be -20.2 mV, thus indicating the presence of negative charges
on their surface. The contact angle measurements revealed that wettability of plain chitosan film reduced
due to the addition of carbon dots. It was found that impregnation of carbon nanoparticles
(CNPs) into chitosan film resulted in an almost seven-fold decrease in the water absorption capacity of
the film. The equilibrium moisture uptake (EMU) data of plain chitosan and CNPs-loaded chitosan
films were interpreted by GAB isotherm and related parameters were also evaluated.

Conclusion:

It may be concluded from the above study that BTCA, a tetra carboxylic acid compound,
can conveniently be used as a precursor to synthesize negatively charged carbon dots. These carbon
dots, when loaded into plain chitosan film, cause an effective crosslinking within the chitosan film
matrix. The CNPs-loaded films produce green fluorescence when exposed to UV light.
Os Estudos Culturais como novas Humanidades
Authors: Martins Moisés de Lemos
Published: May 2019

É meu propósito, neste estudo, argumentar a ideia de que os Estudos Culturais podem ser encarados como novas humanidades. Os Cultural Studies centram a atenção nos estudos étnicos, pós-coloniais, comunicacionais, antropológicos, etnográficos e feministas, e apenas “muito marginalmente” têm-se interessado pela literatura e pelos estudos literários (Aguiar e Silva, 2008). Mas são precisamente esses domínios, investidos pela ‘Social Science’, e não pelas ‘Arts’, que se constituem como pedra de toque da modernidade. E é neles que se joga, hoje, em grande medida, a ideia que temos do humano. A interrogação que hoje é feita, tanto sobre o humano como sobre a modernidade, tem como pano de fundo a translação tecnológica da cultura, da palavra para a imagem (Martins, 2011a). A minha proposta tem em atenção esse debate, sublinhando entretanto o compromisso que os Estudos Culturais têm com atual e o contemporâneo, o que também quer dizer, com o presente e o quotidiano.

Do direito à educação e da sua circunstância: reflexões sobre educação em democracia e seus obstáculos
Authors: Cunha Paulo Ferreira da
Published: May 2019

O direito à educação é um direito não apenas constitucionalmente consagrado e, como tal, um direito fundamental positivo, mas também um direito natural, decorrente da natureza das coisas e da necessidade vital de aperfeiçoamento da Pessoa. Ao contrário de alguns direitos que são concebidos como meras prerrogativas atribuíveis diretamente a beneficiários praticamente sem obstáculos ou refração, o direito à educação, pela sua natureza, também necessita para se efetivar de um ambiente propício e de mediadores: não apenas os veículos educativos, familiares, mediáticos e escolares, como ainda pessoas que desejem ser titulares ativos desse direito. No presente artigo são assinalados diversos aspetos da contextualização dessa “circunstância”, como diria Ortega, deste direito singularíssimo, que tanto demanda a ação do Estado, como dos agentes educativos e culturais, como ainda e fundamentalmente dos cidadãos sujeitos e não objetos da educação. Pretende-se, assim, refletir de forma originária e sem complicadores ou preconceitos politica ou educacionalmente corretos sobre o Direito à Educação e os seus protagonistas, bem como sobre as suas dificuldades, que existem mesmo em contexto democrático.

POLÍTICAS CULTURAIS DO GOVERNO LULA
Authors: Rubim Antonio Albino Canelas
Published: May 2019

Para serem avaliadas, as gestões de Gilberto Gil (2003-2008) e Juca Ferreira (2008 em diante) no Ministério da Cultura do Brasil não devem ser comparadas apenas com a gestão Francisco Weffort (1995-2002). Um estudo rigoroso requer que elas sejam confrontadas com as três tristes tradições que marcam as políticas culturais nacionais: a ausência, o autoritarismo e a instabilidade. O trabalho analisa as políticas culturais desenvolvidas pelo Governo Luiz Inácio Lula da Silva com este foco.
Selfies de vítimas: imagem e autenticidade em postagens de redes sociais
Authors: Biondi Angie Gomes
Published: May 2019

Este texto procura refletir sobre a exposição crescente que o autorretrato, nomeadamente, as selfies, de pessoas que se enunciam vítimas têm adquirido em sites de redes sociais. As vítimas de violência se declaram e se apresentam em fotografias que expõem situações marcadas pela dor e sofrimento. Pensadas como gesto que configura uma forma de relato de si, estes materiais indicam os aspectos que participam do processo de visibilidade no contexto on-line. Deste modo, dois pontos se destacam no exame deste material: a) funcionam como recurso à afirmação da autenticidade como um dos índices culturais da moral que define o que seria aceitável à declaração daquele que se diz vítima; b) promovem formas de interação afetiva com os demais usuários. O exercício de análise privilegia exemplares recentes veiculados através de uma hashtag de campanha, pelo Instagram.
ENCANTARIA MARANHENSE DE DOM SEBASTIÃO
Authors: Ferretti Sergio F.
Published: May 2019

Nas noites de lua, nas areias da Ilha dos Lençóis no Maranhão, Dom Sebastião aparece como touro encantado, e alguns conseguem ver seus tesouros nas dunas. A família de Dom Sebastião, com filhos, nobres de sua corte, cavaleiros, vaqueiros e soldados, é constituída de seres encantados que são recebidos em transe nos rituais de cura e de tambor de mina. O touro de Dom Sebastião constitui uma das vertentes formadoras do festival do bumba-meu-boi e de outras manifestações populares no Maranhão. Através de observações no batizado do boizinho de Dom Sebastião, num ritual de cura, procuramos compreender elementos do sebastianismo maranhense, analisando a presença do sincretismo e do hibridismo como forma de compreensão da religião e da cultura.
Religião e economia como culturas universalistas
Authors: Costa Joaquim
Published: May 2019

A ideia deste artigo persegue-me desde o momento em que, preparando um colóquio, li, num artigo de um economista, que “a economia é uma teologia”; especificava ele, ainda, que Marx, Hayek e Keynes foram “os teólogos mais influentes do século XX”. Aos poucos, comparando a expansão dos grandes monoteísmos universalistas com a da moderna economia de mercado, apercebi-me de que o paralelismo entre religião e economia é mais do que um ocioso exercício de analogia. No expansionismo universalista que os alimenta, na linguagem com que invadem e descrevem o mundo, ambas impregnam as nossas vidas e tornam-se a infraestrutura somática das sociedades que conquistaram. Não por acaso, o problema da pobreza e do seu valor teológico tem gerado cismas na Igreja Católica. É coisa atávica e não nos deveria surpreender, pois a pobreza é, a um tempo, economia e teologia.
O ENCONTRO ENTRE O ÓCIO E A CULTURA: Reflexões sobre o ócio criativo desde a investigação empírica
Authors: Cuenca Cabeza Manuel , Cuenca Amigo Macarena
Published: May 2019

O ócio é um setor significativo pela sua importância económica e a sua incidência no bem-estar ou nos estilos de vida atuais. O desfrute da cultura, como decisão pessoal do sujeito que a experiencia, também é considerado ócio; mas nem a cultura como facto humano é toda ócio, nem o ócio é todo cultura.O artigo estuda o encontro entre ambos os conceitos a partir da ideia de ócio criativo e os dados que são obtidos da investigação empírica. Desde um ponto de vista humanista, a relação ócio-cultura tem um dos seus grandes referentes no ócio criativo, que vem a ser a realização atual do conceito de ócio herdado da cultura clássica. O desenvolvimento do tema é baseado na análise do estudo sobre Atividades Culturais em Espanha 2010-11 e de dados referidos em duas investigações concretas, realizadas no Instituto de Estudos de Ócio da Universidade de Deusto, Bilbau (Espanha): uma sobre as práticas e experiências de ócio na Região Autónoma do País Basco e outra focada na Experiência de Ócio em pessoas que praticam um ócio consolidado. Entre as conclusões destaca-se o desequilíbrio que existe entre a cultura da receção e a suavertente criativa, pelo que se torna necessário diferenciar entre práticas de ócio associadas a uma visão ampla do ócio humanista, e práticas culturais, cujo significado se tem vindo a reduzir ao consumo das chamadas indústrias culturais. Mesmo assim, é evidente que há um amplo leque de confluência e, em ambos os casos, é possível diferenciar as duas vertentes, criação e recriação, como âmbitos diferenciados da mesma realidade.
NOVOS DESAFIOS PARA A INVESTIGAÇÃO SOBRE CULTURA: Prioridades de investigação no domínio cultural da EU
Authors: Ortega Nuere Cristina , Verdet Peris Isabel
Published: May 2019

O objetivo deste artigo é identificar quais são as prioridades da pesquisa sobre a cultura no início do século XXI, no âmbito da União Europeia. Para conseguir isto, as prioridades dos programas Europeus e as políticas públicas são extraídas dos principais documentos políticos relacionados com a cultura. São analisados os programas europeus que financiam projetos culturais e também são fornecidos alguns exemplos de projetos já financiados. A análise dos dois tipos de fontes bibliográficas torna possível a dedução dos desafios enfrentados pelos investigadores hoje em dia no domínio da cultura na UE. Os resultados desta análise de comparação mostram que as novas áreas temáticas são uma das áreas de culturas em que há alguns "nichos de pesquisa". Embora este artigo se focará nas novas áreas temáticas, a análise mostra que a internalização e o networking, bem como a transferência de conhecimentos, também são prioridades de pesquisa. Em outras palavras, deverá haver mais iniciativa nestes campos e projetos de investigação que abordem estas questões, encontrando assim financiamento através de programas da UE nos próximos anos.
Pós-verdade, neoliberalismo e cinismo institucional
Authors: Silveira Sergio Amadeu da
Published: May 2019

Este texto trata da conjuntura política brasileira e do processo que redundou no golpe de Estado que destituiu a presidente eleita Dilma Rousseff. Articulando as noções de regime de verdade, práticas discursivas e política de escândalo, o texto avança na descrição da formação de uma articulação das classes dominantes, corporações da mídia, Ministério Público e Poder Judiciário para destruir as possibilidades eleitorais das forças de esquerda no Brasil, abrindo caminho para a implementação do receituário neoliberal. Apropriando-se principalmente da ideia do combate à corrupção, os velhos esquemas do poder econômico organizam a construção de discursos e ações de Estado que compõem o cinismo institucional como política de Estado.
Música eletrónica de dança: ambiguidades discursiva
Authors: Ferreira Alexandre , Rabot Jean-Martin
Published: May 2019

Este artigo reflete sobre as ambiguidades que constituem os discursos em torno da música eletrónica de dança, pondo em evidência o carácter socialmente construído dos mesmos. Sob o ponto de vista dos Estudos Culturais, incidiremos particularmente no house e no techno. A sua estreita ligação com a tecnologia constituiu uma mudança paradigmática na forma como se faz e entende música no século XXI. Pretendemos posicionar o nosso olhar para a importância que este género pode representar na formação dos estudantes de música em Portugal, designadamente no ensino superior.
Aceleração, desaceleração, tortura sônica e inércia: temporalidades de partidas de futebol
Authors: Marra Pedro Silva
Published: May 2019

Este artigo explora as relações temporais da disputa futebolística, buscando evidenciar como o controle da passagem do tempo e das mudanças de andamento da partida – o que introduz transformações rítmicas a partir de eventos e lances do jogo – tanto por parte dos jogadores quanto da torcida por meio do som são fundamentais para a constituição do resultado esportivo. A pesquisa da qual parte o trabalho visa compreender como torcida e jogo constroem-se mutuamente no espetáculo futebolístico por meio da manipulação de sonoridades, compreendidas como mediações técnicas entre corpos diferentes. Aqui, quatro destas técnicas são delimitadas e exploradas: a aceleração, a desaceleração, a inércia e a tortura sônica. As observações partem de trabalho de campo realizado em partidas do Clube Atlético Mineiro, entre 2008 e 2015, nos Estádios Independência e Mineirão, em Belo Horizonte.
Transcrição do Vale do Ave em som: criação de uma linguagem espácio-sonora
Authors: Silva Cidália Ferreira , Leite Eugénia Aguiar
Published: May 2019

A transcrição do Vale do Ave em som (Leite, 2014) surge do cruzamento da representação do território com a representação sonora, aplicada à interpretação de duas amostras do Vale do Ave – o centro de Guimarães e o “entre Brito e Silvares” –, através da criação de notações gráficas ambivalentes, que simultaneamente representam o espaço e o som. Neste artigo, apresenta-se o processo de transcrição criado, o qual tem como questão geradora: como transcrever o espaço urbano em som? Aquilo que tradicionalmente se denomina de paisagem sonora (Augusto, 2014; Schafer, 1993) reflete sobre o som existente nos lugares. Este artigo inverte esta proposição, pretendendo transcrever a espacialidade dos lugares em som. Assim neste contexto, o termo “ouvir” o território não se refere aos sons reproduzidos pelos carros, pelo vento, pelas folhas das árvores, etc., mas sim ao som resultante da composição espacial. Os resultados da investigação comprovaram o vínculo entre o espaço e o som, uma vez que a composição musical correspondente a cada amostra não só é distinta, como nos remete para a sua espacialidade, abrindo um campo interdisciplinar passível de novas interseções em outros lugares, com possibilidades mútuas de inovação tanto ao nível da composição espacial como da composição musical.
