Aesthetics as politics: Reflections on an architecture of dissensus
Authors: Tatla Helen
Published: July 2021

Contributing to the debate for a democratic articulation of the urban environment, this paper focuses on the reinterpretation of the relation between thinking and perception in Kant's Second Moment of the Analytic of the Beautiful, by Jacques Rancière. Rancière argues that the dissensual operation implied in Kant's definition of the beautiful involves a superimposition that transforms the given form or body to a new one. Social emancipation for Rancière becomes an aesthetic matter, a matter of dismemberment of a body animated by a particular belief. When the loss of destination implicit in aesthetic experience, as explained by Rancière, disrupts the way in which bodies fit their functions in a social order, then a political effect is produced. The aesthetic effect presupposes dis-identification. Within the aesthetic community, political subjectivisation is based on a dis-identification process. Furthermore, reconsideration of modernity for Rancière means going back to Schiller's idea of the aesthetic education of man which originated in Kant's Analytic of the Beautiful. We can argue with reference to an architecture of dissensus that through a process of dislocation, dismemberment and dis-identification, tradition opens up to a constant transformation to something new, involved in a never-ending play between totally different layers that make up everyday experience.
Implications of Vattimo's 'Verwindung' of modernism in architectural theory
Authors: Stevanović Vladimir
Published: July 2021

In the postmodern era, besides new approaches to architectural practice, substantial changes happen in architectural textual production owed to the inflow of the postmodern transdisciplinary theory in architectural discourse. Theorists, critics and historians of architecture gladly use the contribution from philosophy, political sciences, sociology, art theory and literary criticism to categorize and explain postmodern architectural styles or tendencies, no longer unifying them exclusively by means of formalistic aspects dating from the same period. Now, topics and paradigms from various postmodern theories are being implemented and thus created the phenomenon of the translation of a theory into an instrument of architectural purpose. In most cases, theoretical outlooks serve as a cover which the theorists of architecture use to formulate the poetics of architects, proclaim desirable models of reception, and develop the stance on the disciplinary and socio-historical contexts. However, it becomes interesting when the same architectural works of a single or several architects are differently interpreted by different theorists of architecture. The paper examines these premises on a specific example, which is: 1) demonstrated in practice by Catalan architecture of the 1980s; 2) the point of convergence between de Solà-Morales, Rossi and Frampton; 3) underlain by Vattimo's philosophical concept of Verwindung of modernism.
"Learning from Detroit?": From materialised dreams to bitter awakening aesthetics around decayed shopping malls
Authors: Somhegyi Zoltán
Published: July 2021

Shopping malls were and are still particularly popular since the first ones were built in the 1950s. Curiously, both their frequent visitors and their most avid critics see them as the materialisation of the consumer society's dream. They are thus often considered as almost being "temples" of consumerism, where the activity of "shopping" substitutes other, more traditional forms of sociocultural engagement. In the recent years we can experience an increasing interest in the documentation of decayed malls from a melancholic-nostalgic viewpoint in dreamy visions that in certain cases makes the images similar to the classical representation of Antique ruins. Is it only by coincidence, or is there a parallel between the appreciation of ruins of the temples of Antiquity and the ruins of the temples of consumerism? In case yes, then what can we learn from the attempts of aestheticisation of this decay? What can these series of artworks reveal on our present condition and approach to space, entertainment, consuming and life? I am bringing in my examination some considerations on Detroit, not (only) on the city itself, that has become a reference point, and sometimes even a "playground" for the analyses of contemporary decay, but on Detroit as a phenomenon or symbol, as well as some considerations based on the re-reading of Venturi, Brown and Izenour's milestone-book.
Towards post-digital aesthetics
Authors: Daudrich Anna
Published: July 2021

Over the past decades, digital technology and media had firmly integrated into almost all areas of contemporary culture and society. In this context, the Internet, computers or mobile phones are no longer considered products of new media, but instead are taken for granted. With this background in mind, this paper suggests taking a post-digital perspective on today's media society. The concept of post-digital refers to an aesthetics that no longer regards digital technology as a revolutionary phenomenon, but instead as a normal aspect of people's daily life. More precisely, post-digital aesthetics deals with an environment where digital technology became such a commonplace that its existence is frequently no longer acknowledged. Based on the analysis of contemporary artworks and practices inspired by their surroundings, this paper aims to bring those phenomena into consciousness that became unnoticeable in the contemporary digital environment. For this purpose, this investigation goes beyond the formal-aesthetic analysis, but instead focuses on the investigation of the receptive act. Concretely, post-digital aesthetics seeks to describe and analyze the changing modes of perception affected by the increased digitization of one's surroundings. In the context of this analysis, aesthetics is thus understood not as the goal per se, but rather as the means to enhance the understanding of contemporary digital culture.
The conjunction of art and life: Ontology of the site
Authors: Matejić Bojana
Published: July 2021

Art becoming life and its relative convergence to the ideality of autarky (aὐtάrceia), implies a maxim which coincides with the emancipatory promise of Art. NEO-Marxist authors have prescribed this maxim to Marx's early works, particularly to the thesis from his Economic and Philosophic Manuscripts of 1844, and elaborated it further on these grounds. This maxim has been applied by many avant-garde movements up to the contemporary moment: Bertold Brecht's political theatre, Guy Debord's situationism, site-specific art, fluxus, Joseph Beuys's social sculpture, etc. The common denominator of all these avant-garde practices is the imperative of an affirmation of their use-value - their realisation at the site of their own production, as opposed to the abstractness of their placement in the world. The site of this production is the site of the very production of sociability. Accordingly, the aim of this paper is to examine the maxim art becoming life in the wake of Badiou's ontology of the site by using the example of the modality of site-specific works in the conditions of contemporaneity.
"An enemy of our times": Godard's aesthetics of contemporaneity as opposition to synchronization
Authors: Lund Jacob
Published: July 2021

Towards the end of his film essay Histoire(s) du cinéma Jean-Luc Godard calls himself an "enemy of our times", of "the totalitarianism of the present as applied mechanically every day more oppressive on a planetary scale." The article regards Histoire(s) du cinéma (1988-1998) as "a thinking form" that tries to resist the synchronizing, standardizing time of global capital, the pervasive uniformity of the global super-present, brought about by today's televisual and digital communications, which threatens to trivialise the different processes of memory and history, and art and culture in general. According to philosopher Bernard Stiegler, the final stage of capitalism is the control and synchronization of what former CEO of TF1 Patrick le Lay called "available brain time". The paper argues that Godard's work opposes this control and synchronization of our minds through an aesthetics of contemporaneity. The argument is based on the development of a theoretical framework that combines recent theories of contemporaneity with theories of image-politics. Focusing on the interrelation of the individual, the social and the media environments, the paper deals with Godard's image-political creation of temporal contemporaneity through a montage of clips of old films and newsreels, photographs, stills, images of paintings, new footage, advertisements, music, sound and voice recordings, textual citation, narration and commentary.
The cinematic aspect of architecture: The role of time in discussing alternative architectural strategies
Authors: Anđelković Katarina
Published: July 2021

In the search for ways to overcome the negative connotations of applying characteristically traditional practice methods in the current regulation of spatio-visual parameters of the urban environment, we are moving towards discussing alternative 'architecture of relations'. The paper elucidates how film may offer an alternative position in architecture, where urban spaces are thought and designed in closer relation to the potentials of film to manipulate reality, change the mode of perception, provide vision and reconstruct unconscious impulses of the metropolis. The experimental designs show how resonating records of space, time and movement through space may simulate the mapping impulse that inspires an alternative approach to designing spaces. My approach relies upon various knowledge production platforms to detect temporal filiation between cinematic and real space. They are indicated here in the context of postmodern discussions to uncover a new interaction point between cinema and architecture, in order to support time-based modes of reception of architectural and urban ideas.
Above proportions: Reinterpretation of proportion: In between a conceptual and perceptive view of architecture (a communicative dimension of the city)
Authors: Mihajlović Miloš , Subotić Aleksandra , Parežanin Vladimir
Published: July 2021

This paper views proportion as a tool used by planners and architects to achieve a certain quality of space. Considering that proportion is used to observe the correlations between the whole and its parts, the paper examines the aspects of space from the spatial plan of a city to the architectural details. Also, despite the fact that proportion is the correlation of the dimensions of physical elements in space, the paper also perceives proportion through the correlation of the material and immaterial aspects of space. In this way, the focus is shifted onto the level of communication between the architectural - urban space and its users, that is, to orchestration through the perception and experience of space, rather than the outdated, proportional analysis of architectural form.
Beyond scale: Imprinting of everyday life in the architectural and artistic forms
Authors: Krstić Verica , Kordić Milena
Published: July 2021

As a starting point this paper questions the actualization of the concept of the atmosphere in contemporary architectural and artistic research both in theory and in practice. The concept of the atmosphere points to the possibility that the architectural and artistic practices directly operationalize their interests in the problems of everyday life and everyday culture. Architectural and artistic atmosphere are realized in the ratio 1:1, thus surpassing conditions typical for both disciplines separately. Usefulness of the scale of 1:1 is the potential for interdiscursive exchange because it includes the experience of the physical body in space and represents a medium through which the social reality is engraved into the space. We propose that the production of the atmosphere could be a mechanism to imprint everyday life into architectural and artistic forms through real-size-multimediaworks.

Authors: Stojanović Sandra , Geršak Jelka , Trajković Dušan
Published: July 2021

Compression properties of textile materials are useful for determining fullness, softness, smoothness, and stiffness. In addition, compression parameters have significant influence on fabric hand value and quality of textile materials. The present paper reports a study of the sublimation printing process influence on the change in compression properties of knitted fabrics (polyester, cotton, and cotton/ polyester) intended for sportswear manufacturing. For that purpose, the KES-FB3-A Compression Tester was used for measuring compression parameters of knitted fabrics. The parameters, which contributed to the smallest reduction percentage in compression properties of polyester knitted fabrics were yarn linear density and weight. For cotton-rich knitted fabrics sublimation coating powder was used for paper modification to bond disperse dyes to cotton fibres. The analysis of the results showed that the printing process had a smaller influence on the change of compression parameters of polyesters in relation to cotton and cotton/polyester knitted fabrics. It was noted that the printing process had the effect of thickness reduction for all knitted fabrics to varying degrees. Printing process contributed to small decrease in compressibility and specific volume values for polyester knitted fabrics. The modification process contributed to the significant reduction of the compressibility for cotton (from 34.46% to 47.89%) and cotton/polyester (from 38.81% to 50.75%) knitted fabrics. In addition, reduction in specific volume values range from 41.86% to 44.19% for cotton and from 42.37% to 45.75% for cotton/ polyester knitted fabrics was notted.
Theoretical investigation of mollusk shells: Energy landscape exploration of CaCo3 polymorphs and element substitution: A short review
Authors: Škundrić Tamara , Zagorac Dejan , Zarubica Aleksandra , Matović Branko
Published: July 2021

Due to the remarkable properties achieved under ambient conditions and with quite limited components, mollusk shells are very appealing natural bio-composites used as inspiration for new advanced materials. Calcium carbonate which is among the most widespread biominerals is used by mollusks as a building material that constitutes 95-99% of their shells. Within the investigation of calcium carbonate polymorphs present in the shells, diverse theoretical and experimental studies were performed, however, further research of these crystalline forms is required. There are very little researches on the energy landscapes of biogenic calcium carbonate which can provide us information about the free energies of already known as well as newly discovered plausible structures. To investigate the structural, mechanical, elastic, or vibrational properties and to predict new possible structures of biogenic calcium carbonate, different calculation methods could be employed. Some of these studies are presented and discussed in this paper.
Fuzzy inference system based prediction of electrical discharge machining quality
Authors: Gostimirović Marin , Rodić Dragan , Sekulić Milenko
Published: July 2021

Quality and productivity are two most important performances of electrical discharge machining (EDM). This paper presents the application of a fuzzy inference system (FIS) for prediction of machining quality in the EDM process. Specifically, the FIS conducted modeling of geometrical accuracy and surface finish of EDM machined parts. With the fuzzy inference system model, the input variables are discharge current and pulse duration, while the output parameters are gap distance between the electrodes and surface roughness of the workpiece. The performance of the proposed FIS provides a more effective selection of the EDM input values, which leads to better machining conditions and quality of the final product. The fuzzy inference system based modeling of the EDM process showed a very good agreement compared to the experimental data.
Methods and working styles of companies management
Authors: Andrejić Marko , Ketin Sonja , Čabarkapa Obrad
Published: July 2021

Privatization and change of ownership structure in organizations dealing with production and services, intense competition and accelerated technological development have emphasized the importance of holders of management functions in business systems. Consequently, managers have become the subject of great interest of both private owners and the state. The work of managers is essentially a reciprocal, psychodynamic and two-way process that affects the attitudes, beliefs, behavior and motivation of employees, as well as business success. What distinguishes successful managers from unsuccessful ones is the method and style of work and life of managers, attitude towards subordinates and other influential factors in the work process.
Multicriteria assessment of renewable energy sources in Serbia
Authors: Stojčetović Bojan , Mišić Milan , Đorđević Aleksandar
Published: July 2021

The development of today's economies is inconceivable without energy. However, fossil fuel reserves are declining, climate change is accelerating and some changes in the energy sector are needed. Renewable energy sources are a potential solution for many scientists and practitioners. However, the planning and implementation of renewable energy projects requires consideration of a number of criteria, which is why multicriteria decision-making methods are often used to evaluate renewable energy sources/technologies. Goal of this paper is to evaluate four types of renewable energy sources (photovoltaic, hydro, biomass and wind energy) in Serbia. Analytical hierarchical process and seven criteria were applied. Based on the obtained results, hydro sources are ranked the best. Also, a sensitivity analysis was conducted to determine whether changes in the priority of criteria would cause changes in the range of alternatives. It was found that major changes in priorities are needed for changes to occur, so it can be concluded that the results obtained are relevant.
Fatigue in breast cancer patients during the therapy: Examining the role of demographic and clinical determinants, psychological factors and social support
Authors: Novakov Ivana
Published: July 2021

Cancer-related fatigue is one of the most prominent problems in cancer patients, which often remains inadequately treated, because the etiology of this syndrome is still relatively unknown. This study aimed to examine demographic, clinical, and psycho-social determinants of physical and mental aspects of cancer-related fatigue. The study was conducted on 64 women with a breast cancer diagnosis, aged between 33 and 79 years (M=58.36, SD=11.30) while undergoing radiation therapy. For the assessment of physical and mental fatigue, the Fatigue Assessment Scale (FAS Serbian) was used. Demographic and clinical data, symptoms of anxiety and depression (DASS-21), neuroticism (BFI), and functional and structural social support (Serbian translation MOS-SSS) were examined as well. The results showed that depression, anxiety, and neuroticism correlated positively with both physical and mental fatigue, while structural and functional social support correlated negatively only with the physical dimension. Participants who have a partner reported significantly lower levels of physical fatigue compared to those who are not in a relationship, while such a difference was not detected in the case of mental fatigue. Neuroticism and relationship status were the most important predictors of physical fatigue, while neuroticism alone was the most significant predictor of mental fatigue. The results showed that physical and mental fatigue have different correlates, and that personality traits and social support might be of greater relevance for understanding fatigue, than clinical and demographic factors. These findings may be of importance when assessing the risk factors for fatigue and planning psycho-social interventions to empower breast cancer patients.
Characterizing Long-term Disability Progression and Employment in NARCOMS Registry Participants with Multiple Sclerosis Taking Dimethyl Fumarate
Authors: Salter Amber , Lancia Samantha , Cutter Gary , Fox Robert J. , Marrie Ruth Ann , Mendoza Jason P. , Lewin James B.
Published: July 2021

Background:

Delayed-release dimethyl fumarate (DMF) is effective in relapsing-remitting multiple sclerosis (RRMS), but long-term effects of DMF on disability and disease progression in clinical settings are unknown. We evaluated disability and employment outcomes in persons with RRMS treated with DMF for up to 5 years.

Methods:

This longitudinal study included US North American Research Committee on Multiple Sclerosis (NARCOMS) Registry participants with RRMS reporting DMF initiation in fall 2013 through spring 2018 with 1 year or more of follow-up. Time to 6-month confirmed disability progression (≥1-point increase in Patient-Determined Disease Steps [PDDS] score) and change in employment status were evaluated using Kaplan-Meier analysis. Participants were censored at last follow-up or at DMF discontinuation, whichever came first.

Results:

During the study, 725 US participants with RRMS had at least 1 year of DMF follow-up data, of whom most were female and White. At year 5, 69.9% (95% CI, 65.4%–73.9%) of these participants were free from 6-month confirmed disability progression, and 84.7% (95% CI, 78.6%–89.2%) were free from conversion to secondary progressive MS. Of 116 participants with data at baseline and year 5, most had stable or improved PDDS and Performance Scales scores over 5 years. Of 322 participants 62 years and younger and employed at the index survey, 66.0% (95% CI, 57.6%–73.1%) were free from a negative change in employment type over 5 years.

Conclusions:

Most US NARCOMS Registry participants treated up to 5 years with DMF remained free from 6-month confirmed disability progression and conversion to secondary progressive MS and had stable disability and employment status. These results support the long-term stability of disability and work-related outcomes with disease-modifying therapy.
Oxygen Cost of Walking in People With Multiple Sclerosis and Its Association With Fatigue: A Systematic Review and Meta-analysis
Authors: Rooney Scott , McWilliam Gavin , Wood Leslie , Moffat Fiona , Paul Lorna
Published: July 2021

Background:

This systematic review and meta-analysis aimed to compare the oxygen cost of walking in individuals with multiple sclerosis (MS) and controls and to assess the relationship between oxygen cost of walking and fatigue in individuals with MS.

Methods:

Four databases (CINAHL, MEDLINE, ProQuest, Web of Science) were searched up to September 2020. Studies were included if they recruited adults with MS and either compared oxygen cost of walking in those with MS and a control population or determined the relationship between oxygen cost of walking and fatigue. Meta-analysis of the standardized mean difference in oxygen cost of walking between individuals with MS and controls was performed.

Results:

Nine studies were included in this review, of which 7 compared oxygen cost of walking in individuals with MS (n = 176) and controls (n = 142) and 4 investigated the relationship between oxygen cost of walking and fatigue. Meta-analysis revealed that individuals with MS (with predominantly mild-to-moderate disability) had a significantly higher oxygen cost of walking compared with controls (standardized mean difference = 2.21, 95% CI = 0.88 to 3.54, P = .001). In addition, 3 studies found a significant yet weak positive association between oxygen cost of walking and fatigue.

Conclusions:

Individuals with MS expend more energy when walking compared with controls. This increase in energy expenditure may contribute to the development of fatigue, as some studies found that higher oxygen costs of walking were associated with greater fatigue. Future studies should investigate whether reducing energy expenditure during movement improves fatigue.

Published: July 2021

Automatic differentiation is a technology to differentiate a computer program automatically. It is known to many people for its use in machine learning in recent decades. Nowadays, researchers are becoming increasingly aware of its importance in scientific computing, especially in the physics simulation. Differentiating physics simulation can help us solve many important issues in chaos theory, electromagnetism, seismic and oceanographic. Meanwhile, it is also challenging because these applications often require a lot of computing time and space. This paper will review several automatic differentiation strategies for physics simulation, and compare their pros and cons. These methods include adjoint state methods, forward mode automatic differentiation, reverse mode automatic differentiation, and reversible programming automatic differentiation.

Published: July 2021

Aims: Fungal pathogens are one of the main biological agents causing maize post-harvest loss and affect food security in the country. Thus, this study was conducted to assess fungal pathogens associated to post-harvest maize (Zea mays L.) with especial focus to mycotoxin-producing fungi at producer’s storage condition in different regions of Côte d’Ivoire.

Study Design: A total of 1 500 samples of maize as grains, cobs and husks were collected at rate of 500 samples by region (Gbêkê, Poro, Hambol, Indénié-Djuablin and Gontougo) and sent to the laboratory in order to analyse their sanitary quality.

Place and Duration of Study: This study was carried out during March 2016 to January 2017. The analyses of the collected sample carried out at the Biotechnology, Agriculture and Valorisation of Biological Resources Laboratory of the Félix Houphouët-Boigny’s University, Abidjan.

Methodology: Microbiological analysis was assessed by recording the number of colony in the plate. The contents of aflatoxin and ochratoxin A in the different samples were determined using standard methods.

Results: The total microbial species isolated ranged from 104 to 1011 cfu/g with thermotolerants coliforms (103 – 104) and fecal coliforms (102 – 103). The stored maize samples contained also high amount of yeast and molds (104 to 107 cfu/g). Aspergillus genus was the predominantly fungal isolated in all maize samples with tree species which are A. flavus, A. niger and A. versicolor potential producers of mycotoxins. More importantly, stored maize sample as grain, cobs and husks were affected by aflatoxins (B1, B2, G1 and G2) and ochratoxin A. Sixty per cent of the maize samples, mostly husks, showed aflatoxin B1 (from 12.73 to 130.31 µg/kg) and OTA (from 16.75 to 134.21 µg/kg) concentrations above the Maximum Authorized Limit of 5 µg/kg.

Conclusion: A significant variability from one region to another can be noticed at level of maize quality regardless the type of maize. The sanitary quality of maize seems to be tied to postharvest treatments (drying), type of storage (grains, cobs and husks) and structure of storage.

Neste trabalho, procuramos desenhar os mapas das diversas culturas digitais de meninos e meninas, em Portugal e no Brasil, a partir dos dados de duas pesquisas representativas nacionais: TIC Kids Online e Net Childen Go Mobile. Usamos o termo no plural porque entendemos que os acessos das crianças às tecnologias do online e os usos que fazem delas são diferentes de acordo com o estatuto socioeconômico dos meninos e das meninas (o que implica diferenças também em relação aos níveis de desigualdade social dos países em que elas vivem). Porém, para além do fato de que a utilização da internet está mais bem distribuída pelas crianças portuguesas do que pelas brasileiras e de que a nação da América do Sul apresenta um salto da conexão fixa para a móvel, sem passar pelos portáteis, pode-se afirmar que há uma cultura digital relativamente comum aos dois países, no sentido de que cresce em ambos o uso dos media individualizados, com acesso à internet, como celulares e tablets. Este trabalho é derivado de pesquisa de doutoramento (bolsa Capes), que trata da participação do leitorado no jornalismo infantil no Brasil e em Portugal.

Adolescentes infratores na cena pública: como os media alimentam o debate sobre a redução da maioridade penal // Juvenile delinquents on the public arena: how media influence the debate on the reduction of criminal age
Authors: Cal Danila Gentil Rodriguez , Dos Santos Breno Augusto Mendes
Published: July 2021

Este trabalho pretende compreender como os media mobilizam discursos sobre os adolescentes em conflito com a lei e de que maneira a competição entre esses discursos na esfera de visibilidade midiática contribui para a formação de opiniões públicas sobre a redução da maioridade penal. Focamos a análise nos principais jornais diários do estado do Pará, onde, de acordo com o Mapa da Violência, os índices de violência têm crescido de modo exponencial. Como fundamentação teórica, partimos da ideia do caráter sistêmico dos media (MAIA, 2012) e do conceito discursivo de debate público (DRYZEK, 2004; MENDONÇA, 2010). Para realização da pesquisa, coletamos 426 matérias que abordavam atos infracionais publicadas entre de abril a setembro de 2012 nos jornais O Liberal e Diário do Pará e realizamos análise de conteúdo e dos discursos sobre adolescentes infratores. Os resultados apontam que adoção de uma perspectiva sistêmica dos media complexifica o processo analítico, afastando-o de perspectivas notadamente sensacionalistas, e permite a compreensão nuançada dos modos pelos quais os media investigados participam do debate público sobre a redução da maioridade penal.

This work aims to understand how the media mobilize discourses on adolescents in conflict with the law and how the competition between these discourses in the media sphere of visibility contributes to the formation of public opinions on the reduction of criminal age. We focus the analysis in the major daily newspapers in the state of Pará, where, according to the Map of Violence, violence rates have grown exponentially. As theoretical foundation, we start from the idea of the systemic character of the media (MAIA, 2012) and of the discursive concept of public debate (DRYZEK, 2004; MENDONÇA, 2010). To conduct the investigation, we collected 426 media materials published between April to September 2012 in the newspapers O Liberal and Diário do Pará and performed content and discourses analysis. The results show that adoption of a systemic perspective of the media improve the analytical process, especially rejecting sensationalist perspectives, and allows nuanced understanding of the ways in which the media participate in the public debate the reduction of criminal age.

Authors: Nascimento Fabricio Holanda do , Silva Amanda Fernandes
Published: July 2021

Esta pesquisa tem o objetivo de identificar e analisar a variação das temperaturas de superfície do Município de Viana, Espírito Santo, Brasil, por meio de técnicas de Sensoriamento Remoto, em dois episódios, chuvoso e seco, de 2019, bem como relacionar as classes de temperatura com o uso e a cobertura do solo e a morfologia do terreno. Para tanto, foram feitos levantamentos bibliográficos entre livros, teses, dissertações e artigos científicos que discorrem sobre os principais conceitos aqui tratados (Clima, Climatologia Geográfica, Sensoriamento Remoto, Sistemas de Informações Geográficas etc.), aquisição de bases cartográficas (vetoriais e raster) para a elaboração dos mapas e para aplicação de recursos técnicos de geoprocessamento de imagens de satélite. Os resultados mostraram diferenças significativas na variação das temperaturas, mais elevadas nas áreas urbanas comparativamente às áreas de agricultura/pastagens (8°C) e providas de cobertura florestal (9,5°C), tanto no verão quanto no inverno, associadas às propriedades diferenciadas quanto à produção, à propagação e à conservação de calor no ambiente.

Abstract

SPATIAL VARIATION OF SURFACE TEMPERATURE: CASE STUDY OF TWO EPISODES IN THE MUNICIPALITY OF VIANA, ESPÍRITO SANTO, BRAZIL, IN 2019

This research aims to identify and analyze the variation in surface temperatures in the municipality of Viana, Espírito Santo, Brazil, using Remote Sensing techniques, in two episodes, rainy and dry 2019, as well as to relate the temperature classes with the land use and cover and the terrain morphology. To this end, bibliographical surveys were made between books, theses, dissertations and scientific articles that discuss the main concepts treated here (Clima, Geographic Climatology, Remote Sensing, Geographic Information Systems, etc.), acquisition of cartographic bases (vector and raster) for the preparation of maps and for the application of technical resources for geoprocessing satellite images. The results showed significant differences in the variation of higher temperatures in urban areas compared to areas of agriculture / pasture (8°C) and provided with forest cover (9.5°C) both in summer and in winter associated with different properties as to production, propagation and heat conservation in the environment.
Redes de pendularidade estudantil dos polos sub-regionais do interior de Minas Gerais
Authors: Soares Rafael Santiago , Lobo Carlos , Meneses Isabela Lopes
Published: July 2021

No interior do estado de Minas, o crescimento total bruto de matrículas no ensino superior, entre 1991 e 2010, foi de 371,82%, relativamente maior do que o nacional (309,41%). Cabe, portanto, uma análise sobre as formas de polarização e as características da mobilidade pendular de estudantes na rede de centros regionais no estado. Neste artigo, avaliam-se os fluxos e os padrões de distribuição das redes de pendularidade de estudantes entre os centros regionais do interior do estado de Minas Gerais, tendo como base os dados do Censo Demográfico de 2010. Foram analisados os movimentos de pendularidade de estudantes de vinte e dois centros considerados de alta centralidade, aqui denominados sub-regionais. A interpretação foi elaborada por meio da avaliação das redes de distribuição espacial, conjugada com a mensuração de indicadores como a Distância Média ponderada (DMp) e a Razão de pendularidade escolar (RPe), o que permitiu a distinção dos movimentos estudantil e laboral. Os resultados indicam a magnitude de deslocamentos intrarregionais e maior abrangência espacial de polarização de cinco sub-centros regionais. Quinze municípios apresentaram RPe maior que um, ou seja, possuem a prevalência na atração da pendularidade estudantil, o que mostra a relevância do papel das instituições de ensino na atração populacional.

Abstract

NETWORKS OF STUDENTS’ PENDULAR MOVEMENTS FOR THE SUBREGIONAL POLES OF THE COUNTRYSIDE OF MINAS GERAIS

In the countryside of Minas Gerais state (MG), the absolute growth in the period between 1991 and 2010 was of 371,82%, which is a bit higher than the National growth (309,41%). Such context raises questions about the forms of polarization and the students’ pendular fluxes between regional centres. In this article I evaluate these fluxes and the patterns of distribution of the networks of students’ pendular motion among the regional centres of the countryside of MG based on the data of the Demographic Census of 2010. I analysed students’ pendular movements from 22 centres located in the exact centre of the state, which I named “subregionals” for the purposes of this paper. My interpretation was built through the evaluation of the networks of spatial distribution compared with the measurement of the Average Weighed Distance (DMp in Portuguese) and with the Rate of Students’ Pendular Movements (RPe in Portuguese), which allowed me to distinguish between the students’ and workers’ movements. The results I obtained reveal the magnitude of the interregional movements and a higher spatial encompassment of the polarization of five regional centres, seats of Federal Universities. Fifteen municipalities have shown an RPe higher than 1, which means they present a prevalence of students’ pendular movements, revealing the importance of theeducational institutions’ role in the spatial dynamics of the population.
Habitar o terroir do vinho: o sentimento da paisagem de Mendoza, Argentina
Authors: Gabardo Wagner
Published: July 2021

Este ensaio reflete sobre o terroir do vinho enquanto espaço construído a partir da relação harmônica entre seres e natureza, tomando como base o conceito de“habitar poético” de Heidegger, a fenomenologia espacial de Dardel e a geografia emocional de Andreotti. Busca-se revelar as relações emotivas que vitivinicultores estabelecem com o espaço que habitam e que alimentam as narrativas do terroir, em uma abordagem poética da paisagem. Para ilustrar esta dinâmica dialógica, recorreu-se à análise de um vídeo promocional sobre a região de Mendoza, Argentina. Os depoimentos apresentados no vídeo demonstram como as narrativas dos autóctones impregnam simbolicamente as paisagens do vinho, espelham um ideal de habitar poético e produzem lugares míticos no imaginário dos viticultores. Observou-se, ainda, o papel do sabor como uma forma de registro geográfico e o vinho como fértil objeto de análise desta relação entre a experiência do gosto e a expressão da paisagem.

Resumé

HABITER LE TERROIR DU VIN: LE SENTIMENT DU PAYSAGE DE MENDOZA, ARGENTINE

Cet essai réfléchit sur le terroir du vin en tant qu’espace construit à partir de la relation harmonique entre les humains et la nature, basé sur le concept Heidegger de «la poétique de l’habiter», la phénoménologie spatiale de Dardel et la géographie émotionnelle d’Andreotti. Il cherche à révéler les relations émotionnelles que les vignerons établissent avec l’espace qu’ils habitent et qui nourrissent les récits du terroir, dans une approche poétique du paysage. Pour illustrer cette dynamique dialogique, nous avons utilisé l’analyse d’une vidéo promotionnelle sur la région de Mendoza, en Argentine. Les témoignages présentés dans la vidéo montrent comment les récits des autochtones imprègnent symboliquement les paysages du vin, ils reflètent un idéal de la «poétique de l’habiter» et produisent des lieux mythiques dan l’imaginaire des vignerons. Nous avons également observé le rôle du goût comme forme d’enregistrement géographique et du vin comme objet fertile d’analyse de la relation entre l’expérience du goût et l’expression du paysage.
