Software Sensors for Order Tracking Applied to Permanent Magnet Synchronous Generator Diagnostics: A Comparative Study
Authors: Rambault Laurent , Allouche Abdallah , Etien Erik , Sakout Anas , Doget Thierry , Cauet Sebastien
Published: April 2021

The paper deals with software sensors which facilitates the diagnosis of electrical machines in non-stationary operating conditions. The technique targeted is order tracking for which different techniques exist to estimate the speed and angle of rotation. However, from a methodological point of view, this paper offers a comparison of several methods in order to evaluate their performance from tests on a test bench. In addition, to perform the tests, it is necessary to initialize the different methods to make them work correctly. In particular, an identification technique is proposed as well as a way to facilitate initialization. The example of this paper is that of a synchronous generator. Angular sampling allows the spectrum to be stationary and the interpretation of a possible defect. The realization of the angular sampling and the first diagnostic elements require the knowledge of two fundamental quantities: the speed of rotation and the angular position of the shaft. The estimation of the rotation speed as well as the estimation of the angular position of the shaft are carried out from the measurement of an electric current (or three electric currents and three voltages). Four methods are proposed and evaluated to realize software sensors: identification technique, PLL (Phase Locked Loop), Concordia transform and an observer. The four methods are evaluated on measurements carried out on a test bench. The results are discussed from the diagnosis of a mechanical fault.

Two Severe Prolonged Hydrological Droughts Analysis over Mainland Australia Using GRACE Satellite Data
Authors: Wang Wei , Shen Yunzhong , Wang Fengwei , Li Weiwei
Published: April 2021

In recent years, many droughts have happened over mainland Australia, especially the two severe prolonged droughts, from 2006 to 2009 and 2018 to 2020, resulting in serious water scarcity. Therefore, using the Total Storage Deficit Index (TSDI) from the Gravity Recovery and Climate Experiment (GRACE), we analyzed the two severe prolonged droughts from the perspective of the affected area, spatial evolution, frequency, severity and drought driving factors. The results show that the affected area of Drought 2006–2009 ranged from 57% to 95%, and that of Drought 2018–2020 ranged from 45% to 95%. Drought 2006–2009 took its rise in southeastern Australia and gradually spread to the central part. Drought 2018–2020 originated in the southwest corner of the Northern Territory and northern New South Wales, and gradually expanded to Western Australia and the whole New South Wales respectively. During Drought 2006–2009, Victoria suffered drought all months, including 59% mild drought and 41% moderate drought, North Territory had the highest drought severity of 44.26 and Victoria ranked the second high with the severity of 35.51 (cm months). For Drought 2018–2020, Northern Territory was also dominated by drought all months, including 92% mild drought and 8% moderate drought, the drought severities were in North Territory and Western Australia with 52.19 and 31.44 (cm months), respectively. Finally, the correlation coefficients between the two droughts and Indo-Pacific climate variability including El Niño-Southern Oscillation and Indian Ocean Dipole (IOD) are computed. By comparing the correlation coefficients of Drought 2018–2020 with Drought 2006–2009, we find that the impact of the El Niño on the hydrological drought becomes weaker while IOD is stronger, and the role of Southern Oscillation on droughts is diverse with the quite different spatial patterns. The results from Fourier analysis confirm that the two hydrological droughts are all related to Indo-Pacific climate variability but with slightly different driving mechanisms.
Assessing Accuracy of Land Cover Change Maps Derived from Automated Digital Processing and Visual Interpretation in Tropical Forests in Indonesia
Authors: Sari Inggit Lolita , Weston Christopher J. , Newnham Glenn J. , Volkova Liubov
Published: April 2021

This study assessed the accuracy of land cover change (2000–2018) maps compiled from Landsat images with either automated digital processing or with visual interpretation for a tropical forest area in Indonesia. The accuracy assessment used a two-stage stratified random sampling involving a confusion matrix for assessing map accuracy and by estimating areas of land cover change classes and associated uncertainty. The reference data were high-resolution images from SPOT 6/7 and high-resolution images finer than 5 m obtained from Open Foris Collect Earth. Results showed that the map derived from automated digital processing had lower accuracy (overall accuracy 73–77%) compared to the map based on visual interpretation (overall accuracy 80–84%). The automated digital processing map error was in differentiating between native forest and plantation areas. While the visual interpretation map had a higher accuracy, it did not consistently differentiate between native forest and shrub areas. Future improvement of the digital map requires more accurate differentiation between forest and plantation to better support national forest monitoring systems for sustainable forest management.

Authors: Navarro Alejandro , Young Mary , Macreadie Peter I. , Nicholson Emily , Ierodiaconou Daniel
Published: April 2021

Coastal wetland ecosystems, such as saltmarsh and mangroves, provide a wide range of important ecological and socio-economic services. A good understanding of the spatial and temporal distribution of these ecosystems is critical to maximising the benefits from restoration and conservation projects. We mapped mangrove and saltmarsh ecosystem transitions from 1991 to 2015 in south-eastern Australia, using remotely sensed Landsat data and a Random Forest classification. Our classification results were improved by the addition of two physical variables (Shuttle Radar Topographic Mission (SRTM), and Distance to Water). We also provide evidence that the addition of post-classification, spatial and temporal, filters improve overall accuracy of coastal wetlands detection by up to 16%. Mangrove and saltmarsh maps produced in this study had an overall User Accuracy of 0.82–0.95 and 0.81–0.87 and an overall Producer Accuracy of 0.71–0.88 and 0.24–0.87 for mangrove and saltmarsh, respectively. We found that mangrove ecosystems in south-eastern Australia have lost an area of 1148 ha (7.6%), whilst saltmarsh experienced an overall increase in coverage of 4157 ha (20.3%) over this 24-year period. The maps developed in this study allow local managers to quantify persistence, gains, and losses of coastal wetlands in south-eastern Australia.

Published: April 2021

Significant challenges of the COVID-19 pandemic highlighted that features of a modern, sustainable and resilient city should not only relate to fulfilling economic and social urban strategies, but also to functional urban design, in particular, related to urban blue and green infrastructure (BGI). Using results from a web-based questionnaire survey conducted May–July 2020 in Moscow (Russia) and Perth (Australia), this paper provides insights regarding citizens’ needs for and values of urban BGI as well as their changes during and after the COVID-19 restrictions. Survey data collected during the lockdown period have captured information about people’s ability to access green and blue spaces within urban BGI, inequalities in access, feelings, and values as well as needs and perceived pathways of future development of urban natural environment. In both cities, lockdowns limited access of people to green spaces which affected their mental and physical health. Survey results revealed that the quality, functionality, and location of open green spaces illustrated a disparity in distribution, meaning that in many cases several communities from particular neighborhoods suffered from limited access to BGI. Furthermore, in addition to analyzing perceptions and values of urban nature during the COVID-19 pandemic, some suggestions for improvement of urban BGI based on the survey responses are provided.

Published: April 2021

Urban renewal is an ideal approach to promoting the value of the urban fabric and improving the sustainability of the urban environment. This study, which shows the continuity of research on sustainable urban renewal, aimed to identify sustainable urban renewal literature based on a library analysis of scientific research since 2000. A total of 3971 scientific papers from the SCIE (Science Citation Index Expanded) and SSCI (Social Sciences Citation Index) databases were reviewed to examine how research concerning “sustainable urban renewal” has emerged and developed in the past 20 years. The h-indices and impact factors of the most relevant journals in urban renewal and sustainable development since 2000 were analyzed. The most frequently cited articles were analyzed using analysis of social networks (VOSviewer). The results revealed potential future focuses of research and guidelines that link urban renewal and sustainability: the engagement of all stakeholders in the decision-making process; the involvement of residents in projects; the development of cooperation between towns and cities; the preservation and reuse of built and industrial heritage while respecting environmental law; and, finally, the search for new financing techniques. These potential future research topics were analyzed in four research areas so that sustainable development can easily be integrated into an urban renewal project.

Authors: Łukiewska Katarzyna , Juchniewicz Małgorzata
Published: April 2021

The competitiveness of the food industry, which is among the most important areas in the Central European economy, is a significant and topical research area in economics. The sector is particularly important for long-term sustainable growth in Central European national economies. Its high competitiveness is an important stabiliser in an environment of global economic instability. This study aimed to assess the relationships between elements of competitive potential and the competitive position of the food industry in E.U. countries. The relationships between these categories were examined using econometric models with the use of panel data. The results of the spatial-temporal modelling of the panel data confirmed the significant impact of production potential on the share of exports, profitability and the synthetic competitive position index, the impact of labour productivity on all analysed competitive position ratios, the impact of labour costs on the trade coverage, profitability and overall competitive position and the positive impact of innovation on profitability. It was found that labour productivity was of the greatest importance in building a competitive position. The results of the research can be used by food industry companies and government authorities in creating competitive advantages for the food industry in international markets.

Published: April 2021

The onboard training environment is important for the continuity of cadets’ maritime careers and for the wider industry. Various studies have been conducted with the aim of improving the onboard training environment of cadets in various respects including education, health and safety, and sexual harassment. However, there is a lack of research that details the problems associated with onboard training and how the safety of cadets is managed in the field. Descriptive and non-parametric statistics were used to analyze the data from 284 cadets from maritime universities and 41 shipping company employees in South Korea collected between March and July 2020. The results show that many cadets are not guaranteed enough rest time and the provision of personal protective equipment. In addition, some companies consider cadets to be crew members or temporary workers. To improve the training environment, recommendations include the evaluation of the ship’s environment to establish whether it is suitable for training, constant monitoring of whether the onboard training guidelines are maintained in the field, strengthening of preventive education on human rights violations, and expanding efforts continuously not only to physically improve the onboard training environment but systematically manage cadets as students.
An Evolutionary Game Research on Cooperation Mode of the NEV Power Battery Recycling and Gradient Utilization Alliance in the Context of China’s NEV Power Battery Retired Tide
Authors: Lyu Xichen , Xu Yingying , Sun Dian
Published: April 2021

Recycling and gradient utilization (GU) of new energy vehicle (NEV) power batteries plays a significant role in promoting the sustainable development of the economy, society and environment in the context of China’s NEV power battery retirement tide. In this paper, the battery recycling subjects and GU subjects were regarded as members in an alliance, and an evolutionary game model of competition and cooperation between the two types of subjects was established. Evolution conditions and paths of the stable cooperation modes between these two were explored. Suggestions were proposed to avoid entering a state of deadlock and promote the alliance to achieve the “win-win” cooperation mode of effective resource recovery and environmental sustainability. The results revealed four types of certain situations, two types of uncertain situations, and one type of deadlock situation for the evolution of alliance cooperation. The factors of the market environment are evident in not only changing the evolution paths and steady-states of the alliance but also in breaking the evolution deadlock. However, the sensitivity of the members in the alliance to different types of parameters varies greatly. It is difficult for the government to guide the formation of an ideal steady-state of cooperation or break the deadlock of evolution by a single strategy, such as subsidies or supervision. The combination of subsidy-and-supervision or phased regulation should be adopted. Only increasing subsidies is likely to weaken the function of the market and have a counterproductive effect.
Estimation of Genetic Parameters and Wood Yield Selection Index in a Clonal Trial of Korean Pine (Pinus koraiensis) in Northeastern China
Authors: Kombi Kaviriri David , Liu Huanzhen , Zhao Xiyang
Published: April 2021

In order to determine suitable traits for selecting high-wood-yield Korean pine materials, eleven morphological characteristics (tree height, basal diameter, diameter at breast height, diameter at 3 meter height, stem straightness degree, crown breadth, crown height, branch angle, branch number per node, bark thickness, and stem volume) were investigated in a 38-year-old Korean pine clonal trial at Naozhi orchard. A statistical approach combining variance and regression analysis was used to extract appropriate traits for selecting elite clones. Results of variance analysis showed significant difference in variance sources in most of the traits, except for the stem straightness degree, which had a p-value of 0.94. Moderate to high coefficients of variation and clonal repeatability ranged from 10.73% to 35.45% and from 0.06% to 0.78%, respectively. Strong significant correlations on the phenotypic and genotypic levels were observed between the straightness traits and tree volume, but crown breadth was weakly correlated to the volume. Four principal components retaining up to 80% of the total variation were extracted, and stem volume, basal diameter, diameter at breast height, diameter at 3 meter height, tree height, and crown height displayed high correlation to these components (r ranged from 0.76 to 0.98). Based on the Type III sum of squares, tree height, diameter at breast height, and branch number showed significant information to explain the clonal variability based on stem volume. Using the extracted characteristics as the selection index, six clones (PK105, PK59, PK104, PK36, PK28, and K101) displayed the highest Qi values, with a selection rate of 5% corresponding to the genetic gain of 42.96% in stem volume. This study provides beneficial information for the selection of multiple traits for genetically improved genotypes of Korean pine.

Published: April 2021

High-precision CO2 emission data by sector are of great significance for formulating CO2 emission reduction plans. This study decomposes low-precision energy consumption data from China into 149 sectors according to the high-precision input–output (I–O) table for 2017. An economic I–O life cycle assessment model, incorporating sensitivity analysis, is constructed to analyze the distribution characteristics of CO2 emissions among sectors. Considering production, the electricity/heat production and supply sector contributed the most (51.20%) to the total direct CO2 emissions. The top 10 sectors with the highest direct CO2 emissions accounted for >80% of the total CO2 emissions. From a demand-based perspective, the top 13 sectors with the highest CO2 emissions emitted 5171.14 Mt CO2 (59.78% of the total), primarily as indirect emissions; in particular, the housing construction sector contributed 23.97% of the total. Based on these results, promoting decarbonization of the power industry and improving energy and raw material utilization efficiencies of other production sectors are the primary emission reduction measures. Compared with low-precision models, our model can improve the precision and accuracy of analysis results and more effectively guide the formulation of emission reduction policies.
Heavy Tetraquarks in the Relativistic Quark Model
Authors: Faustov Rudolf N. , Galkin Vladimir O. , Savchenko Elena M.
Published: April 2021

We give a review of the calculations of the masses of tetraquarks with two and four heavy quarks in the framework of the relativistic quark model based on the quasipotential approach and QCD. The diquark-antidiquark picture of heavy tetraquarks is used. The quasipotentials of the quark-quark and diquark-antidiquark interactions are constructed similarly to the previous consideration of mesons and baryons. Diquarks are considered in the colour triplet state. It is assumed that the diquark and antidiquark interact in the tetraquark as a whole and the internal structure of the diquarks is taken into account by the calculated form factor of the diquark-gluon interaction. All parameters of the model are kept fixed from our previous calculations of meson and baryon properties. A detailed comparison of the obtained predictions for heavy tetraquark masses with available experimental data is given. Many candidates for tetraquarks are found. It is argued that the structures in the di-J/ψ mass spectrum observed recently by the LHCb collaboration can be interpreted as ccc¯c¯ tetraquarks.

Published: April 2021

In Brazil, the correct measurement of the individual firm energy of a plant is important, since it influences directly the determination of its assured energy which is used to establish contracts between power plants and distribution companies, free consumers, and traders. With increasing technological development and greater reliability in the use of automated techniques for monitoring, the use of the Acoustic Doppler Current Profiler (ADCP), has become a reality in Brazil. The ADCP has many advantages over the traditional techniques used for monitoring flows in gage stations of the national hydrometeorological network. In this context, the purpose of this work is to evaluate the impact of the streamflow rating curve measurement on the evaluation of the firm energy of a hydropower plant. A linear optimization model based on dynamic programming was used to calculate the firm energy and it was considered possible measurement errors in the plant’s inflow values and in the parameters of its polynomials that defines the upward and downward elevation. The results pointed that the two considerations had an impact on the calculated firm energy: the inflow measurements and the streamflow rating curve. Therefore, it is shown the importance of an accurate measurement of inflows for the evaluation of the plant’s firm energy.
Integration of Constructed Floodplain Ponds into Nature-Like Fish Passes Supports Fish Diversity in a Heavily Modified Water Body
Authors: Pander Joachim , Nagel Christoffer , Geist Juergen
Published: April 2021

Fish passes facilitate fish movement in fragmented river systems, yet they can also provide important habitat functions. This study investigated the fish community composition of different constructed habitat types (fluvial habitats, floodplain ponds) within fish passes in relation to habitat characteristics in order to deduce recommendations for fish-friendly designs of such structures. Fish community structures within passes differed significantly from those in the main river, comprising a high number of rheophilic species in fluvial habitats (Thymallus thymallus, Hucho hucho, Salmo trutta, Cottus gobio, Chondrostoma nasus, and Barbus barbus), and of stagnophilic species in floodplain ponds (Rhodeus amarus, Scardinius erythrophthalmus, Misgurnus bipartitus, and Tinca tinca). During summer, floodplain ponds also provided important juvenile habitats for the target species C. nasus and B. barbus. Differences between the two habitat types in fish abundance were mostly explained by differences in macrophyte coverage, gravel, boulders, temperature, and current speed. The findings of this study stress the important habitat functions of fish passes. They also suggest that integration of diverse habitat structures, especially of currently hardly considered constructed floodplain ponds into fish passes, can greatly enhance their fish communities and contribute to the restoration of several declining target species of conservation.

Published: April 2021

The quality of aquaculture waters is directly related to water management and aquaculture efficiency, which puts forward higher requirements for water quality evaluation. Based on the consideration of the influence of temporal and spatial changes on the water quality, this paper proposed an improved fuzzy comprehensive evaluation method for aquaculture water quality evaluation. Specifically, constructing a new membership function in the first place, and then selecting dissolved oxygen, pH, temperature and ammonia nitrogen content as water quality indexes for aquaculture, after that, collecting 60 sets of water quality index for different seasons in the past three years, finally, evaluating the water quality of Yangjiabo Aquaculture Base. Meanwhile, comparing it with the evaluation results of the single factor evaluation method and the traditional fuzzy evaluation method. The results show that the water quality of the Yangjiabo Aquaculture Base is at the worst level in winter, and the water quality has improved significantly in spring, summer and autumn. Compared with the other two method, the improved method can comprehensively reflect the changes in water quality with time and space, which is more practical, and so it can be considered to provide a scientific basis for efficient aquaculture and water quality classification.
Habitat-Diversity Relations between Sessile Macrobenthos and Benthic Copepods in the Rocky Shores of a Marine Protected Area

Published: April 2021

In rocky shore systems, sessile macrobenthic assemblages may act as “ecosystem engineers” for many smaller benthic organisms. Thus, the influence of macrobenthic coverage on the diversity and assemblage structure of the harpacticoid copepod fauna was investigated in the rocky shores of a Marine Protect Area (MPA) in the Ligurian Sea (NW, Mediterranean Sea). Two sampling sites were investigated in two seasons at three different depths on both sub-vertical and inclined reefs. A total of 61 species of copepods mainly represented by Miraciidae, Laophontidae, Longipediidae and Thalestridae were found. The complex micro-topography of these substrata provided a wide variety of niches for many species with different lifestyles that suggests the important role of rocky shores to ensure the functioning of coastal ecosystems. The harpacticoid assemblage structure seemed mainly influenced by season and depth. The temporal spread observed is likely one of the underlying mechanisms of niche segregation that allows many species to co-occur in this specific environment along with a subordinate spatial segregation corresponding to the depth gradient. The results seem to support the hypothesis that the different species composition of the “ecosystem engineer” (and consequently its structure changes) are relevant in structuring the copepod assemblages. The comparison with previous data on general meiofauna underlines that higher surrogacy of the taxonomic identification could be used to study rocky shore communities, but the rich diversity that these systems host can only be understood at the lower taxonomic levels. The same holds for future evaluations of impact of environmental changes (including MPA regulations) on meiofaunal assemblages.
A televisão aos Pedaços: O Video Music Awards 2007 e a estratégia discursiva da MTV1
Authors: Soares Thiago
Published: April 2021

O artigo discute a estratégia discursiva da Music Television (MTV) num momento de impasse do mercado musical. Com o consumo de produtos musicais migrando para a internet através do que podemos chamar de uma “cultura líquida”, a emissora adotou, a partir de 2006, o conceito de “televisão expandidada”. Os programas e videoclipes da MTV poderiam ser vistos não só na televisão, mas através da plataforma de compartilhamento de vídeos da internet, o MTV Overdrive. O Video Music Awards 2007, a maior premiação da emissora, é examinado como um exemplo do novo posicionamento discursivo da Music Television.

A revista Ícone publica nesta primeira edição de 2009 um núcleo temático dedicado à reflexão sobre o “cinema mundial”. A definição ampla do espectro da temática revelou abordagens distintas de análise de produções cinematográficas feitas fora do contexto brasileiro. Do clássico cinema soviético ao spaghetti italiano, passando por produções chinesas e hollywoodianas, a diversidade dos temas aciona uma instigante complexidade das pesquisas nacionais e internacionais sobre a arte cinematográfica. Acreditando na importância cultural de nossa produção e na possibilidade concreta de uma inserção internacional dos filmes rodados no país, este número tem a intenção de debater tendências estéticas e produtivas do cinema em pontos diversos do planeta, sublinhando semelhanças e diferenças, rupturas e continuidades com a estética e os modos de fazer do cinema nacional.
Orson Welles na Perspectiva do World Cinema
Authors: Paiva Samuel
Published: April 2021

É objetivo deste trabalho compreender em que medida o cinema de Orson Welles poderia ser inscrito no chamado “World Cinema”. Em pauta de discussão teórica na contemporaneidade, ou seja, em um contexto de globalização, esse cinema, ainda que não esteja definido precisamente, vem sendo cogitado como algo que diz respeito a um “multiculturalismo policêntrico”. Nesse sentido, a figura da “viagem”, perseguida como elemento propulsor de um deslocamento internacional, será o ponto a partir do qual aspectos da vida e obra de Orson Welles serão observados como indicadores de um cinema que sinaliza uma perspectiva mundial.
‘Reading’ the Cinema of Zhang Yimou: Between the Chinese and the Global
Authors: De la Garza Armida
Published: April 2021

How are national identities transformed? If they are mostly narratives of belonging to a community of history and destiny to which people subscribe, those boundarymaking procedures that constitute the political field by instituting difference can provide a tentative answer to this question. This paper is concerned with one such cultural practice, namely film viewing. Globalisation, a boundary-blurring practice, has been the backdrop against which transformations in national identity are often discussed, either bemoaned as cultural imperialism or celebrated as ongoing hybridisation. This piece of research took Zhang Yimou’s controversial film “Hero” as a point of departure, and asked groups of Chinese audiences how they understood the Chinese identity it conveys. Although it is still a work in progress, provisional results are reported below.

Claves para la reforestación de los medios
Authors: Palomo Bella
Published: April 2021

Uno de los acontecimientos más difíciles de olvidar de estos primeros diez años de historia del periodismo del siglo XXI será la crisis estructural que ha tambaleado al sector al final de esta década. Cientos de medios han desaparecido y decenas de miles de periodistas han perdido sus empleos. Durante 2009, profesionales y académicos se han unido para realizar una crítica constructiva que aporte soluciones viables para reinventar los medios. Los ejes fundamentales de este rescate son el reencuentro de los medios con Internet, influido en parte por los imperativos de la convergencia; la aproximación a la audiencia; la creación de productos hiperlocales y el rediseño tanto de las publicaciones en papel como de los cibermedios. Con el mismo objetivo se ha realizado este artículo, donde se utiliza la metáfora de la reforestación para fijar pautas racionales sobre el tipo de medio a ‘plantar’ para que tenga futuro y a qué tipo de cuidados debe someterse para que crezca saludablemente.

A problematização teórica contribui para des-naturalizar essa dimensão tão presente na rotina produtiva.
Rede Record e Teledramaturgia: entre a inovação e a tradição
Authors: Marakami Mariane Harumi
Published: April 2021

O artigo possui como objetivo discutir o modo de produção de telenovelas pela Rede Record, especialmente após o processo de renovação da sua grade de programação ocorrida em meados de 2005, em uma tentativa de competir com a hegemonia de sua principal concorrente, a Rede Globo. Conferimos especial atenção à trama Vidas Opostas (2006), que representou o maior fenômeno da teledramaturgia da Record nesse período, seja no quesito audiência, seja na inovação temática e discursiva.
A Potência do Irrepresentável nas Fotografias de Fait!
Authors: Lombardi Kátia Hallak
Published: April 2021

Este artigo propõe a discussão de algumas mudanças no estatuto da fotografia contemporânea em contexto de conflito, insegurança e instabilidade e suas implicações no espectador. Imagens da dor e da guerra são publicadas constantemente pelos veículos de comunicação, acabando por gerar uma verdadeira iconografia do sofrimento. É possível uma imagem menos atrelada ao drama, ao acontecimento em si e à noção de testemunho e objetividade, características consideradas indispensáveis no fotojornalismo cotidiano, também conter traços que nos levem à reflexão e à rememoração de conflitos passados? O livro Fait (2009), de Sophie Ristelhueber – que apresenta uma série de 71 imagens da Guerra do Golfo, no deserto do Kuwait – é usado para apontar novas configurações da fotografia de guerra. O silêncio e uma certa fragilidade da inscrição dessas imagens abrem espaço para problematizar a potência do irrepresentável.
A Reportagem Fotográfica e a Publicidade Governamental: o caso da revista Era Nova/1925
Authors: Golzio Derval Gomes
Published: April 2021

A década de 1920 é de fundamental importância para o cenário da fotografia no Estado da Paraíba, situado no Nordeste do Brasil. Em 27 de março de 1921 surgiu “ERA NOVA – Revista Quinzenal Ilustrada”, pioneira no impulso da fotografia de imprensa e, já em seu primeiro número, expõe em sua capa uma imagem fotográfica de dimensões 10X15 centímetros. A característica predominante nesta fase da imprensa na Paraíba é de distanciamento entre fotografias e textos, porém em 1925 os editores de Era Nova inauguram uma nova maneira de editar imagens fotográficas. Neste artigo nos propomos apresentar o uso das imagens fotográficas na formação da opinião pública em proveito do poder constituído, em uma época em que as limitações tecnológicas dificultavam a edição e o emprego da fotografia nos jornais e revistas.

A Montagem das Assinaturas nos Arquivos e Coleções de Fotografias
Authors: Pimentel Leandro
Published: April 2021

Enquanto a apropriação das fotografias pela História valoriza o seu poder ilustrativo e a memória factual, no âmbito da arte e outras abordagens históricas menos ortodoxas são evidenciados e assumidos os apagamentos, lacunas, opacidades e anacronismos das lembranças evocadas pelas coleções e arquivos fotográficos. Este ensaio, ao buscar perceber a latência de vozes caladas pela história oficial, visa repensar a potência política desses acervos e a capacidade da fotografia produzir memórias e afetos partilháveis, que cintilam discretos como relíquias veladas que aguardam uma nova montagem para se manifestar.
Comunicação e Semiótica da Cultura: cinema como texto cultural
Authors: Vargas Gilka
Published: April 2021

O presente artigo, inserido no campo de estudos da Comunicação, buscou nos estudos da Semiótica da Cultura de origem russa, através das formulações teóricas de Yuri Lotman, subsídios teóricos para compreender o cinema, meio de comunicação de massa, como um texto cultural. Partindo deste recorte, procuramos apontar como Claúdio Assis, cineasta brasileiro e sua equipe construíram, através da articulação dos textos (sistemas de signos) característicos da linguagem cinematográfica a sequência de abertura da personagem Wellington Canibal, do filme Amarelo Manga (2003, Brasil).
Semiótica da propagabilidade: Uma abordagem sistemática de memes e virais de Internet
Authors: Marino Gabriele , Lima Cecília Almeida Rodrigues
Published: April 2021

Este artigo propõe uma abordagem semiótica aos memes de Internet, um domínio discursivo que, embora represente uma importante e crescente forma de letramento, tem sido largamente ignorado pela Semiótica. Desde o início dos anos 2000, a expressão ‘meme de Internet’ tem se referido a uma ampla variedade de conteúdos de mídia em circulação na Internet, como bordões, imagens com legendas e os chamados vídeos ‘virais’. Memes de Internet são “propagáveis” – são eficazes, desmontáveis, personalizáveis e replicáveis. De uma perspectiva semiótica, eles são tipos diferentes de textos que circulam graças à disseminação hipertextual: notadamente, por um processo de transformação (samples, remixes) e imitação (remakes). Sua sintaxe exibe estruturas que espelham as diferentes operações de manipulação (bricolagem) de seus criadores e isso serve como um gancho para a agência dos usuários, convidando-os, por sua vez, a espalhar, modificar ou recriar o texto. No nível semântico, apesar da variedade de temas e figuras que carregam, todos possuem um elemento marcante (punctum), geralmente lúdico (uma incongruência, um ‘erro’), que serve como gancho para o engajamento dos usuários.
Confissão positiva, polêmica e agir racional nas práticas e interações do pastor Silas Malafaia no Facebook
Authors: Freire Adriana do Amaral
Published: April 2021

Este artigo propõe analisar os discursos presentes na fan page do Facebook do pastor Silas Malafaia, da igreja neopentecostal Assembleia de Deus Vitoria em Cristo, à luz das teorias da ação comunicativa e interação simbólica, tomando como base o conceito de Habermas (2012), e do poder em Foucault (1979; 2001) e Bordieu (2003). A presença do discurso religioso nos ambientes digitais da internet é favorável a questionamentos, contudo, são as construções das falas religiosas e as suas marcas ideológicas, corporificadas no ambiente do ciberespaço, que se destacam na análise. Assim, para localizar os indícios dessas práticas e delimitar um vasto conteúdo religioso na web, a fim de observar tais fenômenos ideológicos, elegemos a fan page do pastor evangélico Silas Malafaia, como espaço digital de observação. Destacamos na pesquisa as falas atribuídas ao pastor e as interações dos seus seguidores para revelar como as categorias citadas emergem no conteúdo extraído do ciberespaço. Observou-se que no polo do emissor o conteúdo apresentou um gênero mercadológico amparado na Teologia da Prosperidade e que, também, são utilizadas expressões e frases que trazem um sentido de superioridade como conotação principal. A pesquisa evidencia ainda os comportamentos dos atores que compõem a rede e que legitimam a diversidade cultural e, inclusive, religiosa, do ambiente digital.
Truth Study Center e as condições para o pensamento a partir de fotografias.
Authors: Feldhues Marina
Published: April 2021

Este trabalho procura refletir sobre se é possível pensar sobre a realidade do mundo, procurar compreender a realidade, por meio da fotografia. Para tanto, parte das proposições levantadas por Susan Sontag sobre o assunto. Na sequência, faz uma revisão teórica das proposições de Sontag à luz das reflexões trazidas por Jacques Rancière sobre imagem, operações de arte e montagem; Walter Benjamin sobre o ato de narrar; Gerry Badger e László Moholy-Nagy sobre narrar como fotos; e Gilles Deleuze sobre o pensamento como experiência.  Por último, procuramos analisar, com base nas reflexões trazidas pelos autores mencionados, como as operações artísticas da instalação Truth Study Center de Wolfgang Tillmans, contribuem para refletirmos sobre a experiência de pensar a realidade do mundo a partir de fotografias.
Imagens que contam: guerra e memória em Moçambique
Authors: Andrade Catarina Amorim de Oliveira , Jácome Márcia Larangeira
Published: April 2021

Este artigo se debruça sobre o filme Terra Sonâmbula (Teresa Prata, 2007) para buscar a potencialidade da imagem de guerra, desde sua proveniência à destinação (MONDZAIN, 2017). Nesse sentido, questionamos: o que constitui uma imagem de guerra? Como se configura essa imagem no filme? De que modos tal imagem tangencia e/ou se contrapõe a uma narrativa hegemônica no contexto de conflitos de guerra, evidenciando-se como dimensão importante nos processos de (re)construção da história e da memória individual e coletiva em uma nação independente? A partir dessas indagações, importa pensar a imagem considerando que a sua construção de sentidos se dá por meio do imbricar de domínios – afetivo, político, sociocultural, estético, econômico, tecnológico - e, sobretudo, que envolve processos como o pensamento, a percepção, a memória (BERGSON, 2011), engendrando narrativas que se movem entre a permanência de tradições e mudanças nas práticas sociais para tratar da experiência da guerra.
Carta ao Leitor
Authors: Duarte Eduardo
Published: April 2021

Nesta presente edição a revista Ícone apresenta em seu dossiê uma reunião de trabalhos que articulam - de lugares, autores e abordagens distintas - o exercício de observar as imagens a partir de dinâmicas em que elas contam suas próprias histórias. As imagens sempre assim o fizeram, independentemente dos enquadramentos de significação que as epistemologias representativas impuseram sobre elas.
Fotografia e Representação da Memória: do olhar de Vishniac à instalação de Rosângela Rennó
Authors: Nino Maria do Carmo , Farache Ana , Gondim Rosemary M.
Published: April 2021

Este texto pretende, precisamente, abordar dois casos em que há uma passagem da fotografia para o fotográfico e entre duas estratégias de representação da memória. No primeiro caso tratamos de algumas fotografias do russo Vishniac e sua peculiar maneira de remeter o observador para um tempo que aparentemente não mais existe, mas que se reinventa através da visão atual das próprias imagens produzidas no contexto da Segunda Guerra Mundial. O segundo caso refere-se à instalação Hipocampo, de Rosângela Rennó, na qual, apesar da "ausência" de imagens fotográficas, é pela instauração do fotográfico que a memória se rearticula e permite a relação do observador com a obra.
