Authors: Carvalho Luisa Cagica , Moreira Sandrina B. , Dias Rui , Rodrigues Susana , Costa Berta
Published: June 2020

Designing circular economy (CE) implies the adoption of a set of circular principles that support a society for the future. Understanding how CE principles influence attitudes to consume green products is a key factor aligned with consumer trends. This chapter aims to study how CE principles influence attitudes to consume green products in a particular case of fashion industry. Very few empirical studies on the perceptions of the fashion “users” exist. This chapter aims to bring some inputs to this topic. The methodology uses a path analysis study based on a sample of 110 respondents collected in a higher education institution in Portugal. The estimated model allows to test the relation between a set of variables, and the study reveals that: CE principles have a direct effect on the attitudes on the green products consumption in fashion industry in the sample considered.
The Circular Economy of Plastics
Authors: Júnior Nelson Beuter , Faccin Kadígia
Published: June 2020

Plastic is an indispensable material for modern society. However, plastic waste is at the center of the current debate due to its presence and persistence in aquatic ecosystems. The literature recognizes that this problem is mainly due to the traditional linear economic model. The circular economy is a model based on the practices of reduction, reuse, recovery, and recycling of materials and energy. Circular economy solutions for plastic could hold the key to its present and future sustainability. Investigating the studies already done about plastic in the context of a circular economy is fundamental to understanding where we are and where we can go.

Published: June 2020

Computational biology is the research area that contributes to the analysis of biological information. The selection of the subset of cancer-related genes is one amongst the foremost promising clinical research of gene expression data. Since a gene can take the role of various biological pathways that in turn can be active only under specific experimental conditions, the stacked denoising auto-encoder(SDAE) and the genetic algorithm were combined to perform biclustering of cancer genes from huge dimensional microarray gene expression data. The Genetic-SDAE proved superior to recently proposed biclustering methods and better to determine the maximum similarity of a set of biclusters of gene expression data with lower MSR and higher gene variance. This work also assesses the results with respect to the discovered genes and spot that the extracted set of biclusters are supported by biological evidence, such as enrichment of gene functions and biological processes.

Authors: Shaheen Sadia , Bari Muhammad Waseem
Published: June 2020

This study investigates the relationship between learning strategies and innovative work behavior. The author chooses business organizations (e.g., textile industry, sports industry, and pharmaceutical companies) for the purpose of data collection. Particularly, those employees are targeted who avail business tours and conferences on a regular basis. Hence, the convenience sampling technique is used to collect data. A total of 800 questionnaires were distributed, but 535 proper filled questionnaires having response rate 66.87% were utilized. Data were collected in two-time waves. At T1 (Time lag 1), data were collected regarding employee demographics (e.g., gender, age, and education and work experience) as well as independent variables (e.g., cognitive learning strategies as well as behavioral learning strategies). At T2 (Time lag 2), data were collected on the dependent variable (innovative work behavior). The results of the study indicate that CLS and BLS have a positive impact on IWB. Managerial and theoretical implications are also discussed along with limitations and future directions.
Role of SOR Theory in Business Tourism Activities for Effective Knowledge Transfer
Authors: Hanif Sadia , Ahsan Ali
Published: June 2020

This study takes on a course of “phenomenon before theory” approach. For that purpose, firstly, the phenomenon regarding knowledge transfer barriers is developed, and then it is confirmed through expert suggestions. Knowledge transfer theories from project management literature are then applied and systematically reviewed against observed phenomenon to obtain the desired solutions. The systematic review of knowledge transfer theories is conducted through content analysis. The observed gaps are then filled with pluralism with components of required theories. The findings were that the discussed theories are not fully mitigating the knowledge transfer hitches. The most important factor for competence development is effective learning during the knowledge transfer activities which has not been addressed by the knowledge transfer theories. The chapter proposes a “Pluralistic Learning Theory for Project Knowledge Transfer” as a practical solution for all sorts of business tourism activities to transfer knowledge effectively.
Contribution of Social Capital to Innovation
Authors: Bengrich Mustapha , Azzahidi Adil , Omrane Amina
Published: June 2020

In today's uncertain environment, companies should develop solutions to meet the global competition trends and the rapidly changing customer demands. In fact, to gain a competitive advantage, organizations should be equipped with knowledge, which is considered as an essential resource, rather than with traditional resources, such as durable assets or material/technical resources. In other words, investing in intangible assets that are difficult to imitate, such as social capital, promotes dissemination and exchange of accessible knowledge used by organizations. Such knowledge management processes enable firms to enhance their capacity of innovation as well as their creativity skills. The objective is therefore to develop a literature review that helps enrich and in-depth understanding the dynamics of social capital within an industrial cluster (i.e., a common geographical area).
Greenways and Sustainable Urban Mobility Systems
Authors: Zawawi Abdulrahman A. , Porter Nicole , Ives Christopher D.
Published: June 2020

This chapter describes how greenways can be a constituent of sustainable urban mobility (SUM) systems that reduce automobile dependence while simultaneously having positive environmental and social co-benefits. It begins by providing a brief background on the harmful effects of automobile dependency. A chronological review of the evolution of greenways as a typology, divided into five generations starting from pre-1900 until today, demonstrates how various economic, political, environmental, and social factors have shaped blue-green corridors in different cities, mainly in English-speaking countries. The discussion then focuses on the integration process between greenways and SUM planning, as well as highlighting some of the planning challenges and opportunities of (re)developing greenways to support as non-motorized transport corridors. By critically analyzing the evolution of greenways in relation to urban mobility and their integration process, this chapter supports green space, transport, and design professionals to work toward a shared vision of sustainable cities.

Do the professionals planning our towns and cities know? This chapter introduces an analytical tool to estimate the land-take of highways using mapping techniques to produce a plan or percentage figure and makes a comparative analysis across other urban centres. The outcome might be linked to quite different measures of civic success such as urban happiness, pedestrian safety, or retail occupancy.
Shadowing Lines of Stardom and Politics
Authors: S. Shantharaju
Published: June 2020

Rebel star Ambareesh, a popular Kannada film actor and a politician, is considered a cult figure for various reasons including his contentious political career and unquestionable stardom. He was well known for controversial, witty, and sleazy statements in public. Yet he gained considerable attention within the party as he represented dominant Vokkaliga voters in Old Mysore part of the state. A large number of films cast him in scripts comprising a rebellious young man who would take down the entire system single-handedly. In his political career as an MP and state minister, he always shocks his party leaders with his “who cares” attitude like in his films. It is not only the rhetorical, chauvinistic statements alone that gained him popularity. The on-screen jingoism towards a region, roles appealing to feudal set up also welded Ambareesh's image as a “Proud son of Mandya.” The current chapter is an attempt to deconstruct the unique model of “Rebel Star,” which needs to be evaluated in the historical context of Kannada cinema along with reception among shared ideologies.
Theorising the Politics of Yakshi in Malayalam Cinema
Authors: V. S. Chitra
Published: June 2020

The fear of the monstrous feminine, yakshi, may be read as an element of collective political fear, threatening the stability and functioning of established systems of power and normalcy. Films attempted a curious balancing of tradition with modernity. The film representations of female ghosts mark a transformation of Kerala's cultural psyche in its relation with the supernatural. One of the common characteristics of yakshi legends and their film representations in Malayalam is that class/caste identity of the woman plays a significant role in the experiences narrated. The myth of yakshi—a cultural fantasy still popular in Kerala, forming an integral part of Malayalam film industry from 1964 to 2017—is analysed through the subaltern theory popularised by Gayathri Spivak and various other theorists together with the psychological theories of the conscious evolved by Freud and Jung. The refashioning of the image from the voluptuous and monstrous one to a more realistic and relatable image proclaims the politics and the social context of fear evoked through this terrible concept.

Published: June 2020

Begging, the practice of imploring others to grant a favour, a gift of money, with little or no expectation of reciprocation, has been prevalent since before the dawn of recorded history. It has been regarded with high esteem in ancient India, the profession of begging considered as an intricate societal concern in the present-day scenario. Religious understanding of people has its contribution to the acuteness of this complex problem. However, it is interesting to observe that with the evolution of society, the mendicants have moved from their traditional methods while adopting modern approaches for begging. As intricate research conducted in the impending theme, this chapter aims to expand the panorama and investigate the psycho-socio exploration of beggars reference to select Tamil films Pichaikaran and Naan Kadavul. It also carries out an extensive study in Coimbatore and Tirupur districts of Tamil Nadu. Furthermore, this research endeavours to scrutinise the comparison and differentiation of the beggars' narratives of survival in their reel and real lives.
Representation of Marginalization in Indian and Iranian Cinema
Authors: Kamble Chandrakant Goutam
Published: June 2020

Cinema is a reproduction of reality, and it cannot separate from real life. Cinema as art can break social, cultural, and languages barriers. India is rich in cinema culture, accommodating several films in regional language. Marathi cinema, one among several local cinemas, has its own space and remains an attraction among the audiences. Starting its journey from Shree Pundalik directed by Dadasaheb Torne to Naal directed by Sudhakar Reddy, the cinema attempts to send social messages on varied subjects. However, a particular cinema depicting the issue of marginalization remains critical. It is the Marathi cinema that sincerely attempts to describe the problems of marginalization. The cinema Fandry (2014) directed by Nagraj Manjule tries to represent caste discrimination, Dalit, and marginalization. It is not the Indian cinema only, but rather cinema worldwide has been serving the issues of marginalization to break the social and economic barrier.
Exclusion and Inclusion of Tribes in Satyajit Ray's Cinema
Authors: Poddar Susmita
Published: June 2020

The Adivasis or original inhabitants of India occupy more than 8% of India's total population and contribute a rich cultural inheritance in the Indian cultural milieu. In large part of Central, East-Central, and North-Eastern India, the so-called mainstream people have intensive contact with the tribal people. They keep feelings of hatred in their mind about these tribes. This hateful and annoying attitude of the larger society towards tribal people has been inevitably reflected in the literature, art, and other expressive media of the so-called higher community. Film media also, though in a limited range, evidently reflects such feelings, such attitudes. Parallel cinema sometimes brings up the life of the forest dwellers and Dalits. Such movies mainly focus on backward peoples' struggle for survival and unbearable exploitation of their life. However, tribal people are rarely portrayed accurately, and whenever it happens, the view of the upper-class people towards the backward tribes become prominent.
Film as a Reflection of Society
Authors: Thangavelu Asha Priya
Published: June 2020

Movies have become such an integral part of man's life that it is tough to imagine a world without this form of entertainment. This world can be larger than life, or it can be about the hustle and bustle of everyday life, or it can paint the heart-wrenching stories of the ostracised and abused sections of society. Social film genres help one to awaken to a sense of responsibility and to show empathy towards emotional situations. Even though films have been able to record the different social changes, its impact has never been systematically explored. This chapter is an attempt to conduct a systematic study of applying the reader-reception theory in a few films in Tamil and to study their impact on society. The films chosen for study are Aruvi, Mercury, Mersal, Velaikaran, and Nisabdham, which were bold cinematic portrayals of sexual abuse of children. These socially enlightening films help in reaching the audience and creating awareness among them. They influence the thought process in a positive way and help one to try to do his/her bit in order to be of help to humanity.

Authors: Mukherjee Das Mou
Published: June 2020

With the emergence of digital media, prosumers are providing a new direction of film funding. Enthusiastic cine-goers are ready to invest in scripts that they believe in by identifying alternative financial resources. Crowdfunding has recently emerged as a funding option for all the creative-cultural industries in general. Although the Indian market is still a novice, the creative explorers are ready to take on the chances to vent their artistic expressions. Therefore it is essential to understand what drives people to either create or fund these projects. In this context, this chapter aims to study the basic premise of crowdfunding in Indian films and analyse the concept of prosumers.
Identification Criteria of Heritage
Authors: Passeiro Vanessa Batalha
Published: June 2020

At a decisive moment in the life of humankind on Earth, when the destruction of its natural and cultural heritage becomes an imminent threat, an ontological reflection reveals itself crucial. There is a lack of clarity in the current paradigm regarding the identification of natural environments, cultural landscapes, and artificial environments, so this chapter aims to contribute for a debate about them. More precisely, a methodology developed by Machado in the context of ecosystems, establishing relationship with the different typologies of tangible heritage, is proposed. The importance of distinction between various typologies of environments and heritage is supported by the fundamentals of environmental ethics. Founded upon them, the concept of cultural landscape is discussed. The chapter also addresses the concept of artificiality, which is a key tool to comprehend the biosphere state of damage and the genesis of the geological epoch in which we live, the Anthropocene. This is, after all, the reason why it is urgent to protect natural and cultural heritage.

Authors: Nazir Sajid , Patel Shushma , Patel Dilip
Published: June 2020

The increased processing power of graphical processing units (GPUs) and the availability of large image datasets has fostered a renewed interest in extracting semantic information from images. Promising results for complex image categorization problems have been achieved using deep learning, with neural networks comprised of many layers. Convolutional neural networks (CNN) are one such architecture which provides more opportunities for image classification. Advances in CNN enable the development of training models using large labelled image datasets, but the hyper parameters need to be specified, which is challenging and complex due to the large number of parameters. A substantial amount of computational power and processing time is required to determine the optimal hyper parameters to define a model yielding good results. This article provides a survey of the hyper parameter search and optimization methods for CNN architectures.

Authors: Meddouri Nida , Maddouri Mondher
Published: June 2020

Knowledge discovery in databases (KDD) aims to exploit the large amounts of data collected every day in various fields of computing application. The idea is to extract hidden knowledge from a set of data. It gathers several tasks that constitute a process, such as: data selection, pre-processing, transformation, data mining, visualization, etc. Data mining techniques include supervised classification and unsupervised classification. Classification consists of predicting the class of new instances with a classifier built on learning data of labeled instances. Several approaches were proposed such as: the induction of decision trees, Bayes, nearest neighbor search, neural networks, support vector machines, and formal concept analysis. Learning formal concepts always refers to the mathematical structure of concept lattice. This article presents a state of the art on formal concept analysis classifier. The authors present different ways to calculate the closure operators from nominal data and also present new approach to build only a part of the lattice including the best concepts. This approach is based on Dagging (ensemble method) that generates an ensemble of classifiers, each one represents a formal concept, and combines them by a voting rule. Experimental results are given to prove the efficiency of the proposed method.

DRESS: A Distributed RMS Evaluation Simulation Software
Authors: Agate Vincenzo , De Paola Alessandra , Lo Re Giuseppe , Morana Marco
Published: June 2020

Distributed environments consist of a huge number of entities that cooperate to achieve complex goals. When interactions occur between unknown parties, intelligent techniques for estimating agent reputations are required. Reputation management systems (RMS's) allow agents to perform such estimation in a cooperative way. In particular, distributed RMS's exploit feedbacks provided after each interaction and allow prediction of future behaviors of agents. Such systems, in contrast to centralized RMSs, are sensitive to fake information injected by malicious users; thus, predicting the performance of a distributed RMS is a very challenging task. Although many existing works have addressed some challenges concerning the design and assessment of specific RMS's, there are no simulation environments that adopt a general approach that can be applied to different application scenarios. To overcome this lack, we present DRESS, an agent-based simulation framework that aims to support researchers in the evaluation of distributed RMSs under different security attacks.

Published: June 2020

This study had two objectives - firstly, to analyze the total static and dynamic capacity of agricultural storage in Paraná State, Brazil and secondly, to verify if the storage followed the growth of grain production. The study was performed by mesoregion for the 2013/2014 and 2014/2015 crop years. The methodology used was descriptive from an agricultural database of the Secretariat of Agriculture and Supply (SEAB), of the National Register System of Storage Units (SICARM), interviews were also made with agroindustrial cooperatives and official agencies. It was identified that in Paraná State there is an insufficiency of 17.75% of total static capacity of warehouses to comply with the total grain production (soybean, 1st and 2nd corn crops, and wheat). The results showed that the total dynamic capacity of warehouses is sufficient in the mesoregions of Eastern Center, Southern Center, Northern Center, and Metropolitan. Therefore, storage units vary uniformly in most municipalities, not following the growth of total grain production in the state of Paraná.

Phytosociological studies are essential for the elaboration of conservation strategies for the Cerrado. The goal of this study was to survey two areas of cerrado stricto sensu: Fazenda Canaã and Fazenda Providência, located in the Municipality of Porto Nacional, State of Tocantins. There were 10 plots of 100 m2 allocated in each area. All individuals with circumference equal to or greater than 10 cm, at ground height ≥10 cm were sampled, soil samples were taken for physical-chemical analysis. Sampling in Canaã resulted in 379 individuals belonging to 28 families and 50 species. In Providência, there were 300 individuals from 27 families and 49 species. The Shannon-Wiener Index for the Canaã was 3.48 and for Providência, 3.45. The studied areas presented a large number of small sized individuals, presenting a reverse J-shaped diameter structure. The Canonical Correspondence Analysis showed significant scores for the first axes (p < 0.05) according to the Monte Carlo test, which explained 70% total variability of the data. The variables with the highest structure coefficient in axis 1 were clay (0.94), pH (0.62) and magnesium (-0.32). On axis 2, the most important variables were aluminum (0.29), silt (0.25) and potassium (-0.078). These soil variables show a differentiation of the study areas.

Published: June 2020

In addition to several local pathophysiological consequences, intestinal injury that is caused by ischemia and reperfusion can result in the development of lesions in remote organs. Curcumin has therapeutic potential because of its antiinflammatory and antioxidant effects. The present study evaluated the effects of curcumin on oxidative and inflammatory parameters in the liver and kidneys in rats that were subjected to intestinal ischemia and reperfusion. The rats were subjected to 45 min. of ischemia followed by 7 days of reperfusion and treated daily with 60 mg kg-1 curcumin. The liver and kidneys were collected, weighed, and biochemically analyzed. Intestinal ischemia and reperfusion increased levels of lipid hydroperoxide (LOOH), decreased levels of reduced glutathione (GSH), and increased the enzymatic activity of superoxide dismutase (SOD), glutathione S-transferase (GST), and myeloperoxidase (MPO) in the liver. Intestinal ischemia and reperfusion decreased kidney weight and increased GST activity in the kidneys. Curcumin prevented these changes in the liver and kidneys. Intestinal ischemia and reperfusion mainly affected the liver, promoting inflammation and oxidative stress. The kidneys underwent repair much earlier than the liver, in which they did not present alterations of MPO or main parameters of oxidative stress after 7 days of reperfusion. Treatment with curcumin had beneficial effects, ameliorating or even preventing injury that was caused by intestinal ischemia and reperfusion in the liver and kidneys in rats

Published: June 2020

The present study describes the length/weight ratio (LWR) of 20 fish species caught in an intertidal area of the Paranaguá Estuarine Complex, southern Brazil. Fish were caught with three beach seine nets, with 2m high, 70m long and distance between knots of 2.5; 4 and 5cm. A total of 880 individuals of 21 species belonging to 11 families were captured, ranging from 5 to 75.5cm in total length. All species analyzed are widely distributed throughout the Southwestern Atlantic. Positive allometric growth (b > 3) was predominant, occurring in 60% species, 35% presented negative allometry (b < 3) and only 5% had isometric growth (b = 3). Many factors could be influencing the distinct growth patterns observed between the literature and the present study, such as the environmental influences, the reduced number of specimens, the sampling methods, the sampling periods and the estimation of the LWR with grouped sexes.

O presente artigo tem por objetivo discutir a memória como projeção para o futuro e não como simples repositório do passado. Deste modo, a memória será estudada como o tempo do devir. A escrita desempenha um papel fundamental nesse processo de preservação e alongamento do presente, que passa a ser narrado como memória para ser lida no futuro. Contribuem para a discussão sobre o tempo e, portanto, sobre a memória, autores como Anne Cauquelin (2008), ao conceituar os ‘incorporais’, e Norbert Elias (1998), que enfatiza a capacidade de síntese do ser humano em apreender o tempo. Após o percurso de revisão bibliográfica, discutiremos o romance Caderno de um ausente, de João Anzanello Carrascoza (2017), como representação da necessidade de construir uma memória para o futuro, para o tempo da ausência. Neste sentido, a narrativa de Carrascoza problematiza a questão do tempo presente, a ausência e o silêncio, que permitem ao narrador-personagem João, um professor universitário com mais de cinquenta anos, agora pai de uma recém-nascida, apreender o presente corroído pelo tempo no momento em que surgem os eventos, o que o leva a uma obsessão por registrar cada movimento como passado, encontrando nas frágeis palavras o único mecanismo para preservar os primeiros anos que testemunha da vida de sua filha. Por fim, tempo e memória serão vistos como ‘incorporais’ que ganham corpo no ato da narrativa, concretizando-se em palavras como representações momentâneas da preservação dos fatos, mas com a capacidade de reduzirem a angústia despertada pela sensação incômoda de ‘não-estar’ que corrói o narrador do romance.
Ressonâncias da épica greco-latina no Ubirajara de José de Alencar
Authors: Dezotti Maria Celeste
Published: June 2020

Este artigo analisa o romance Ubirajara, de José de Alencar, e mostra o débito do autor para com a tradição clássica. Focaliza as relações intertextuais que ele mantém com as epopeias homéricas no tocante a um conjunto de temas, dentre os quais se destacam a excelência guerreira e a hospitalidade. Mostra também como tais temas estão artisticamente entretecidos com os epítetos, recurso estilístico marcante nas epopeias clássicas, de modo a compor uma trama complexa, sustentada em peripécia e reconhecimento. Com base nessa matéria clássica, o discurso do narrador se estrutura como aition, forma narrativa que se propõe a explicar o porquê das coisas, muito apreciado pelos gregos e romanos. O Ubirajara se define no subtítulo como 'lenda tupi'; essa lenda, construída pelo autor, explica as causas que deram origem a um povo indígena chamado Ubirajara, cuja existência histórica é documentada no séc.XVI pelo cronista português Gabriel Soares, conforme registra o próprio Alencar no conjunto de notas que ele apõe à narrativa ficcional. Esta, por sua vez, visa a mostrar os feitos gloriosos do guerreiro Ubirajara, que o tornaram herói epônimo desse povo.
A pragmatic view of hashtags: the case of impoliteness and offensive verbal behavior in the Brazilian Twitter

Studies on impoliteness have encompassed a wide range of social relations and scenarios, including some in which the means for achieving impoliteness is solely, or at least, more saliently linguistic. Among these scenarios, Digital Communication (DC) media, such as Twitter and blogs may incite linguistic manifestations of impoliteness. Since hashtags are ubiquitous in the interpersonal spaces of Twitter, the aim of this study is to investigate how hashtags were used to express offensive behavior and to convey impoliteness in the Brazilian Twitter. We compiled a corpus of 512 hashtags extracted from Brazilian Twitter in 2017 and 2018. Hashtags were manually collected from Twitter ‘trending topics’, and from 3 media sources, written in Brazilian Portuguese. Hashtags associated with offense, including derogatory language, taboo words and mockery were analyzed. Our findings suggest that hashtags served as strategies of impoliteness, since they intensified the contents of the tweets and framed the interpretation of verbal aggressiveness. While they did that, they also helped maximize face attacks in that they inscribed the tweets in a bounded communicative sphere of aggressiveness, mockery and derogatory language. Verbal attacks were mainly intended to politicians and to Brazilian public figures in general. While this permissiveness allowed for greater spontaneity and agility in the exchanges, it also encouraged outrageous uses, which would not be otherwise accomplished were it not for the transient and ephemeral framework of DC. This study shed light on the Pragmatics of DC, showing how ‘new’ features of the medium can be used to convey impoliteness.
O O que mostram e o que apagam os discursos publicitários da indústria da carne brasileira

Published: June 2020

O artigo pretende analisar discursos do agronegócio nacional materializados em campanhas publicitárias audiovisuais desse setor econômico e disseminados pela grande mídia em seus canais, a fim de melhor compreender um paradoxo da sociedade contemporânea: o consumo acentuado de carnes e outros produtos de origem animal, a matança sistemática de milhões de animais simultâneos a um recrudescimento da sensibilidade dos humanos em relação à causa animal. Com base na Análise do discurso derivada de Michel Pêcheux e em contribuições de Michel Foucault, procuraremos identificar o que é dito nos anúncios de indústrias alimentícias e como esses enunciados são formulados. Mais precisamente, nosso propósito é o de analisar a produção de determinados sentidos relacionados à comercialização dos produtos das marcas e o silenciamento de outros considerados disfóricos pelo setor e apagados do seu discurso. O material de análise compreende uma publicidade da Friboi (Figoríficos Fibroi, 2014) com o cantor Roberto Carlos, e um comercial da Sadia (Sadia, 2007) ambientado em um supermercado e protagonizado pelo Seu Juvenal, açougueiro do estabelecimento, e pela Dona Elvira, cliente que procura pelo presunto da marca. Analisaremos esse material mediante um procedimento muito conhecido na AD, a saber: a formação de relações entre os enunciados dos vídeos, entre os vídeos do material e entre eles e outros já ditos do interdiscurso. Essas relações são feitas mediante a identificação e montagem de cadeias parafrásticas: a polissemia constitutiva da linguagem é passível de ser interpretada a partir da produção das paráfrases construídas pelo discurso em suas diferentes condições de produção. Além disso, analisaremos os recursos linguísticos e imagéticos usados na constituição dos audiovisuais sob análise, como as escolhas lexicais, os encadeamentos sintáticos e as modalidades enunciativas. As análises nos permitem observar a produção de sentidos gastronômicos e econômicos, e o silenciamento de outros que assinalam o caráter animal das mercadorias alimentícias.
Solar fraction used in water heating systems for south Brazilian climate changes scenarios

Solar thermal systems consist of water heating from the global solar radiation. Increasing atmospheric concentrations of greenhouse gases tend to increase the earth's surface temperature. The main objective of this work was to estimate the solar fraction obtained by means of solar heating systems for dwellings, for eight locations in the State of Paraná, in scenarios of possible climate changes projected until the end of the 21st century. F-Chart method was used to simulate the performance of solar heating systems based on the monthly average of solar radiation data, which determines the annual solar fraction or percentage of the energy demand that is covered by the solar installation. The results showed that with the impact of the climate changes, the decrease in the percentage of energy demand average that is covered by the solar installation was on average 14.3%, for both scenarios. The simulated values showed a slight decrease trend of radiation data and an increase of the solar fraction. All localities presented a characteristic seasonal behavior, with annual values of solar fraction between 82.4 and 129.8%, according to the studied localities. In relation to the monthly solar fraction, the values between November and March presented averages of solar fraction between 104 and 147.2%. But from May to August, the percentage of energy demand served by the solar installation does not reach the totality, with values between 53.6 and 99.9%. The results prove that the State of Parana has favorable climatic conditions for the installation of solar heating systems, even if it is installed for aggregation purposes, in order to reduce the electric power consumption.
