Item Da fotografia da janela ao retrato do cangaço: elaboração e validação de um documentário como instrumento didático para o ensino de ciências.(2022-06-01) Galvão, Larissa Santos; Silva, Flávia Cristiane Vieira da; http://lattes.cnpq.br/7354496286889274; http://lattes.cnpq.br/9065313312309168The present work has as main scope to present the validation steps of a documentary as a didactic resource for Science Teaching (CE). The short film, called "window to the sun: from the photography of the window to the portrait of the "cangaço", relates the presence of photography in the "cangaço" with the history and evolution of the photographic image, and the scientific phenomena associated with the capture process. Cinema can contribute significantly to the teaching and learning process, including in the natural sciences. The seventh art is able to influence people's lives, so besides contributing to the structuring of scientific knowledge, it provides opportunities for discussions about social issues. Such themes corroborate the student's citizenship education, for he immerses himself in the narratives that often express his reality on the screen. The documentary genre is the most widely used type of film in the classroom, mainly because it is associated with the effort to reproduce reality. To validate the documentary, semi-structured interviews were conducted with Nature Science teachers from a public school in the city of Serra Talhada - PE. Consequently, the transcripts of the interviews were analyzed using elements of the Textual Discourse Analysis (TDA) technique. As a result, the teachers showed that they see the "cangaço" more as history and culture, and associate the movement with Lampião, as a kind of Robin Hood style vigilante. Moreover, the teachers see not only the "cangaço" itself, but also the photograph of the "cangaço", as a possibility to apply in their classes. With this investigation, we can conclude that the documentary is a promising tool to teach Science, capable of providing more contextualized classes, stimulating especially the reflection about the "cangaço" and the presence of Science in the experiences of the "cangaceiros", and among them, practices that are part of the reality of many students. Furthermore, this material can favor activities involving more than one discipline, working together or not. This resource can also be used as a DDC (Documentary of Scientific Dissemination), to strengthen the relationship between society and the academic community, leading to a greater appreciation of science and its social roles.Item Comunidade de siris (crustacea: decapoda: portunidae) da zona de arrebentação da praia de Jaguaribe e estuário do Rio Jaguaribe, Ilha de Itamaracá, Pernambuco, Brasil(2022-06-03) Noé, Karyna Kelly Bezerra; Viana, Girlene Fábia Segundo; http://lattes.cnpq.br/3338076933519392Crustaceans are important members of tropical benthic communities, serving as food for humans. This study aimed to analyze the biometry, abundance and frequency of the population of Portunid crustaceans from Jaguaribe beach and Jaguaribe river estuary in Itamaracá-PE. The collections were carried out at three points: 1) the surf zone, 2) the river mouth and 3) the estuary. The crabs analyzed in this study are bycatch fish collected by trawling. Soon after collected, the crabs were packed in plastic bags and sent to the Bentos Laboratory (LABENTOS) at UFRPE/UAST. Individuals were identified, sexed and quantified. The data obtained were entered into an electronic spreadsheet for analysis of abundance, frequency and diversity. A total of 190 specimens were identified, distributed in five species: Callinectes danae (Smith, 1869), Callinectes ornatus (Ordway, 1863), Callinectes marginatus (Ordway, 1863), Arenaeus cribrarius (Lamarck, 1818) and Charybdis hellerii (Milne Edwards, 1867). Regarding relative abundance, C.danae was considered a dominant species at all points, obtaining 54% at point 1, 66% at point 2 and 65% at point 3. Arenaeus cribrarius was considered abundant at point 1 with 35% and common at point 2 with 20%, it was not collected at point 3. Callinectes marginatus presented 28% at point 3, being considered common, at point 1 it was classified as occasional with 5%. C. ornatus showed abundance at points 1, 2 and 3 respectively with 5%, 9% and 7%, thus being classified as occasional. Charybdis hellerii was classified as occasional with 5%. In the frequency of occurrence, it was found that C. danae is a species considered euconstant with 82% of the collected sample. C. ornatus and C.marginatus, presented 45% each, thus being constant species. A. cribrarius presented 36% and is considered an accessory species. Considered accidental, C.hellerii with only 18% of the total sample. For diversity the values were low for the river mouth (point 2) and for the interior of the estuary (point 3), and low for the surf zone (point 1). The evenness values were equitable, J'= 0.7276 for the surf zone (point 1), J'= 0.691 for the river mouth (point 2) and J'=0.7555 for the interior of the estuary (point 3). Ancova analysis demonstrated a positive growth relationship between carapace width, carapace length, abdomen width, and weight. Differing only for Callinectes danae in relation to carapace width and abdomen width. The low abundance of Charybdis helleri shows that the species is not endangering native crabs in this locality. This study contributed to increase the knowledge about the crabs on the island of ItamaracáItem Compreendendo a importância do marketing nos empreendimentos de aquicultura(2022-05-30) Nogueira, Denise de Barros; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/4846729856694660Aquaculture is an activity that has been on the rise in recent years, however, the need for changes to allow this growth to be socially, economically and environmentally visible. During the critical periods of the pandemic caused by the COVID-19 (SARSCoV-2) virus, aquaculture as well as other sectors were affected and entrepreneurs needed to change strategies to remain effective within the market. Marketing strategies in turn have been significant in directing how to best conduct the enterprise. This study had as its main objective to understand the influence of marketing within aquaculture enterprises. The present work was developed in two stages, the first a literature review in databases, and the second was the application of a questionnaire aimed at aquaculture entrepreneurs. Most of the papers included in this study were published 17.6% in 2006 (3 studies), 17.6% in 2019 (3 studies), 11.8% in 2011 (2 studies), and 11.8% in 2017 (2 studies). During the pandemic 90.9% responded that they needed to update on social networks, WhatsApp being the main network used by all. Finally, the importance of disciplines, courses, and workshops on marketing in aquaculture enterprises is highlighted, so that future professionals can have a basis when entering the job market.Item O discurso sobre o negro propagado no livro didático de história(2021-02-22) França, Aliene maria de; Guimarães, Lílian Noemia Torres de Melo; http://lattes.cnpq.br/7778975209654541; http://lattes.cnpq.br/2827992714449677Item Evaporação no semiárido: análise de sensibilidade e comparação de 7 métodos para estimativa(2022-06-03) Barros, Tays Ferreira; Souza, Luciana Sandra Bastos de; http://lattes.cnpq.br/1186468548787818; http://lattes.cnpq.br/8217101677528263Evaporation is a key variable in understanding the water availability of an environment. Above all, in semi-arid regions, knowledge of water losses is essential and can support the development of activities in these environments. Several models have been proposed to estimate evaporation, these depend on the availability of data, time scale and conditions for which they were developed. This study sought to analyze the sensitivity of the class "A" tank and Penman methods to meteorological variables and compared 7 methods for estimating evaporation for a location in the Brazilian semiarid region. The database used was obtained from a meteorological station located in the municipality of Juazeiro-BA, and comprised the period from 1969-1999. The Penman method was considered standard and correlated with the meteorological variables: temperature (T), humidity (UR), radiation (Rg), wind (Vv) and vapor pressure deficit (DPV), through regression analysis for understanding of the relationships between them. The same procedure was performed for the evaporation measurements obtained through the Class “A” Tank (TCA). Additionally, the information was used to calculate the variable through alternative methods: Stephens–Stewart, Priestley–Taylor, Linacre, Makkink, TCA, Jensen-Haise and Camargo. This information was compared using indices for which Pearson's correlation coefficient (r), coefficient of determination (r²) and Willmont's concordance index are considered. Based on the results obtained, it was possible to verify that the variable DPV presented a high correlation with the evaporation estimated with the Penman and TCA methods. Among the alternative methods, the one that came closest to the method considered standard was Linacre's. Stephens–Stewart, Makkink and Camargo did not show good adequacy in the analyzed region.Item Avaliação da taxa de filtração da daphnia magna cultivada em sistema autotrófico (água clara) e sistema mixotrófico (biofloco) com diferentes dietas ofertadas(2022-06-03) Rodrigues, Mônica de Lima; Abreu, Jéssika Lima de; http://lattes.cnpq.br/6237276943114119; http://lattes.cnpq.br/2300244354976388In aquaculture, the larviculture phase of fish farming is one of the main challenges faced, due to the small size of the cultured individuals and the inherent difficulties in feeding and management. The filtration rate is calculated assuming that the nutrient rate of zooplankton is proportional to the concentration of available food. It is relevant to know the filtration rate in order to know how best to produce organisms, verifying if the type of culture will interfere in the filtration rate, and to observe if there is selectivity regarding the diet offered. The culture was performed in autotrophic system, when inorganic carbon and light are used as energy sources; and mixotrophic, in the presence of organic and inorganic carbon, light, and organic compounds as energy sources. Thus, the present research aimed to know the filtration rate of Daphnia magna (cladoceran) in autotrophic and mixotrophic culture being tested different microalgae diets. The experiment was carried out with six treatments with three repetitions each, based on two factors: culture (autotrophic or mixotrophic) and diet (Chlorella vulgaris, Haematococcus pluvialis (green phase/vegetative phase) and red phase/cystic phase). The water quality variables: temperature (°C), dissolved oxygen (mg.L-1 ) and pH were measured twice a day throughout the culture. The variables analyzed for filtration rate were: filtration rate (TF), cell decay with the presence of Daphnia (K Daph ), cell decay without the presence of Daphnia (K sDaph), ratio with Daphnia (C/C0 Daph), ratio without Daphnia (C/C0 sDaph). The growth variables were: specific growth rate (SGR), doubling time (DT), maximum mean density (DMX), yield (R), and day of maximum density (DMD). As for Dissolved Oxygen, there was a significant difference only for the algae factor. However, the other variables pH and temperature showed no statistical difference, with the pH staying around 7.3 and the temperature around 29° C. As for TF, no statistical differences were found in the treatments. However, certain treatments had higher values for H. pluvialis in the cystic phase in both types of cultures and lower values for H. pluvialis in the vegetative phase. The day of maximum density (MDD) was reached on day 7 in the autotrophic culture with the diet of H. pluvialis in the green phase being fed. Thus, H. pluvialis in the green phase was found to be a well utilized food for Daphnia magnaItem O discurso da vida do sertanejo nas canções de Luiz Gonzaga.(2022-05-25) Nunes, Millena Granja; Guimarães, Lílian Noemia Torres de Melo; http://lattes.cnpq.br/7778975209654541; Não localizadoThis work seeks to investigate the discourse of the life of the sertanejo, by Luiz Gonzaga's songs show the sertão in its identity, social and cultural aspects. We used an interpretative and qualitative methodology. As a general corpus, we analyzed Luiz Gonzaga's álbum, O Rei Volta pra Casa, released in 1982 composed of 14 songs. We are theoretically based on Van Dijk (2004, 2008), Chouliaraki and Fairclough (1999), Fairclough (2001), Wodak (2004), Resende and Ramalho (2019), regarding Critical Discourse Analysis and Oliveira (1998) and Garcia (1987), referring to aspects that deal with the sertão. As a result, we verified that Luiz Gonzaga's songs composing a collection of plurality that deals with the sertão and the lives of those who live there, achieve, through their discursive construction, to give social visibility to the sertanejo as someone who has a life story represented by courage and appreciation of their cultureItem O desmanche das políticas ambientais no Brasil sob a égide do governo da extrema direita: do ativismo ambiental a inércia governamental(2022-05-26) Nunes, Laysla Mikelly Marçal; Torres, Avani Terezinha Gonçalves; http://lattes.cnpq.br/6894754635156771; Não localizadoThe motivation of this monograph was to address the main aspects related to Environmental policies, such as environmental inspection policies and the fight against deforestation and fires that occurred in the three previous governments, comparing them with those of the current government. The research shows what has happened with socio-environmental public policies over the years and what are the effects and consequences generated for the environment. In this context, the methodology used was an exploratory research with a qualitative approach, where the study for the theoretical basis had quantitative data. To achieve this purpose, a bibliographic review was carried out, presenting at first the concept and questions about the dismantling of public policies, secondly, austerity and the policies of the Environment, in a third moment the dismantling of environmental agencies, in a fourth moment , the environmental policies adopted by the Lula government, and finally, the policies adopted during the Bolsonaro government. The research was carried out from an analysis between the governments of former PT ex presidents Lula and Dilma/Temer in contrast with the government of the current president Jair Bolsonaro, where a drop in the budget linked to an increase in the number of fires and deforestation was verified during the Bolsonaro government, reaching alarming numbers. As a result, in addition to the lack of commitment to environmental policy agendas, the government has shown itself to be careless with environmental crises, causing great discontent among environmentalists. It comes to the conclusion that the environmental policies adopted during previous governments have lost their effectiveness in the face of the current government's lack of commitment: the numbers of fires and deforestation have risen again, and parallel to that, the number of inspectors has been falling year after year. Thus, the prospects under the Environment and the Bolsonaro government are increasingly worrying.Item Analisando a opinião de usuários do Twitter em relação ao lockdown no Brasil: um estudo frente à mídia convencional(2022-05-23) Silva, Paulo Alves da; Belo, Ítalo César de Souza; Oliveira, Marcelo Iury de Sousa; http://lattes.cnpq.br/2328386382232459; http://lattes.cnpq.br/3240928244006916; Não localizadoIn the pandemic scenario, several countries sought alternatives to reduce the high rates of contagion and mortality caused by COVID-19. Among the means used was lockdown, which is characterized as the most stringent measure of social isolation. Although lockdown is considered by many to be an excellent tool for health protection, the adoption of this measure divides opinions. In this sense, sentiment analysis emerges as a mechanism that can be used to understand the population's opinion about the lockdown. The social impact caused by this measure contributes to the emergence of articles from the most diverse media vehicles, which can strongly influence the critical thinking of the population. In this context, the present work performed a sentiment analysis to understand how Twitter users reacted to the lockdown implementation in Brazil during the COVID-19 pandemic. In addition, the results of the Twitter analysis were compared with the content coming from the gray literature, focusing on the articles authored by the conventional media, which addressed information about the theme. To carry out this research, data were extracted from the social network Twitter and processed through an ensemble composed of the following machine learning algorithms: Multinomial Naïve Bayes, SVM, Random Forest, MLP neural network, and the Logistic Regression classifier. In addition, Active Learning techniques, through the uncertainty approach, were combined with the ensemble to obtain higher accuracy of the classified data. According to the results, an interesting predominance of sentiments in favor of lockdown was noticed, as well as conflicts between the data obtained by the Twitter sentiment analysis process and information published in the gray literatureItem Explorando o sentimento no twitter sobre a implementação do ensino virtual no Brasil em face da covid-19 .(2022-05-27) Leite, Felipe Antonio Alves; Belo, Ítalo César de Souza; Oliveira, Marcelo Iury de Sousa; http://lattes.cnpq.br/2328386382232459; http://lattes.cnpq.br/3240928244006916; http://lattes.cnpq.br/2530370455196055The high risk of COVID-19 contamination made several countries take social distancing and isolation measures. As a result of these policies, virtual education was the alternative chosen by many schools and higher education institutions to continue their classes. However, that situation, COVID-19-induced, raised some questions about the adequacy of virtual learning concerning students' and teachers' expectations. This work conducted a study of sentiment analysis in Twitter messages to understand the feeling of Brazilian users (teachers and students) about the first months of virtual education in Brazil during a COVID-19 pandemic. Also, it was sought to identify the factors responsible for certain feelings and the consequences of virtual teaching at the beginning of the pandemic. In order to achieve these objectives, sentiment analysis was performed using an ensemble and the Active Learning technique to ensure better accuracy in the classification of the data and, consequently, have an understanding of the current scenario. When analyzing the data, the rejection of teachers and students concerning virtual education during the pandemic was noticeable. It is essential to highlight that factors responsible for this rejection were identified, such as excessive activities, mental exhaustion, and procrastination. In addition, it was found that the adoption of emergency remote teaching had consequences such as anxiety crises, emotional stress, low self-esteem, sleep deprivation, and depression.
