A estória da galinha e do ovo: uma história de fome
Anais e artigos do 28º Fórum Acadêmico de Letras, realizado nos dias 23 a 25 de agosto de 2017 na Universidade Federal da Integração Latino-Americana (Unila) e Universidade Estadual do Oeste do Paraná (Unioeste) com tema: A pesquisa nos cursos de letras em contexto de línguas e culturas em contato.O objetivo deste trabalho é apresentar o conto “A estória da galinha e do ovo”, do livro
Luuanda (2006) de Luandino Vieira, no qual o próprio faz uma crítica a situação política e social de
Angola. O conto, que apresenta uma briga, aparentemente boba entre duas vizinhas, esconde uma
realidade de opressão de um povo negro e pobre de uma colônia governada por brancos. A briga por
um único ovo, tão séria que precisou passar até pela polícia para se tentar apaziguar, revela uma
realidade de extrema pobreza dos musseques angolanos. Para Luandino (2004), encontramos no conto
da estória da galinha e do ovo uma situação ainda colonial, mas já iluminada por fortes tons de um
otimismo libertário, onde juntos os mais velhos e mais novos procuram reconstruir dialogicamente o
mundo fragmentado. O mesmo, por sua vez, procura ser o mais fiel possível à realidade transformando
a obra em um aquário onde ele e seus personagens circulam e, provando, como a fome, a exploração e
o desemprego surgem com evidências. Trata-se de uma realidade social de Angola muitas vezes

Ergonomics evaluation of task demands among kitchen staff
The purpose of this study was to evaluate the workplace demands faced by a group of kitchen staff at six dining centers and to survey musculoskeletal complaints among this sample of workers. The dining centers were located in six different public elementary and middle schools in a city in the south of Brazil. This research was developed following qualitative research design, and the researcher made use of the “Activity Oriented Ergonomics (AOE) methodology.
The AOE focuses on the work analysis that evaluates real work situations that allows a reassessment of work demands. In this case the chosen methodology was a good fit in order to detect issues that can be harmful to workers health regarding ergonomics criteria in the kitchen workplace environment.
The researcher applied different means to conduct the data collection process which included workplace analytical observation, tasks observation, informal conversation with cooks and manager, as well as evaluating tools, forms, and questionnaires. Thus, the observation of the workplace and workers performing their functions focused in analyzing individuals’ operational behavior related to their work requirements.
Data was organized in three different topics including characteristics of participants, workplace environmental conditions, and task analysis, which contains physical and cognitive demands. The analysis of the workplace environment condition emphasized two main topics: 1) layout characteristics of the workplace area such as physical space and equipment aspects; 2) ambiance conditions, which comprises aspects of temperature/humidity, luminosity, and noise. There were essentially four activities that were performed in the workplace, which were food pre-preparation, cooking, meal distribution, and cleaning/sanitation.
Finally, recommendations were made in order to improve the working conditions of the staff as well as their knowledge and awareness regarding everyday aspects of ergonomics. The betterment of ergonomics factors, organizational matters, and environmental aspects can be ultimately beneficial to employees. Importantly, these changes will also benefit the business as a whole, since employees will not only be more productive but also willing to take on the work effectively

Credit Default and Business Cycles: an empirical investigation of Brazilian retail loans
We use microdata from the Credit Information System (SCR) of the Central Bank of Brazil to study the relationship between credit default and business cycles. In particular, we study the first part of the argument underlying the discussion about procyclicality related to the Basel II Accord: that recessions might increase credit defaults and have adverse impacts on the losses in portfolios of lender institutions. We explore both time series and cross-sectional variation in the data. Our data on the individual level are composed of retail loan transactions in two modalities—Consumer Credit and Vehicle Financing—from 2003 to 2008. Our results support the idea of a negative relationship between business cycles and credit default, but less strong than suggested in previous studies that use corporate data. We also find low and dispersed default correlations, and smaller losses in Value at Risk (VaR) experiments than those found in the literature. These results may be possibly explained by the fact that, in the retail sector, loans are given to a large number of individuals, which may help to diversify risks.
Numerical analysis of instability failure modes of cellular steel beams in fire conditions
Beams with long spans are increasingly used in the steel building constructions and usually are used with openings for technical equipment and ventilations systems cut in their web. These elements are structural steel beams that are deeper than normal rolled sections, with distributed circular openings, or other like squared or hexagonal, that are produced by cutting and welding hot rolled steel sections (Westok method). The split halves are then offset and welded together to form a deeper beam with full circular or hexagonal shaped web openings. This method reduces the floor height and therefore the overall height of building.info:eu-repo/semantics/publishedVersio
Control sustentable poscosecha: extractos de Larrea cuneifolia mediados por nades frente a Botrytis cinerea
Botrytis cinerea es un hongo ubicuo que ocasiona la podredumbre gris, una de las principales enfermedades de fruta en poscosecha, siendo responsable de pérdidas económicas. Debido a la creciente preocupación por los efectos adversos del uso de pesticidas, la búsqueda de alternativas se presenta como una meta prioritaria. En este contexto, los extractos de plantas representan una rica fuente de biocompuestos con atractivas propiedades antimicrobianas. Recientemente, los solventes eutécticos naturales (NADES) se han propuesto como agentes extractantes sustentables de compuestos bioactivos a partir de plantas. En el presente estudio, se evaluó un bioextracto de L. cuneifolia basado en NADES hacia B. cinerea. Para este propósito, se usó un NADES compuesto por ácido láctico, glucosa y agua (LGH) como agente de extracción y se comparó con solventes tradicionales en términos de capacidad antioxidante y contenido fenólico total. Además, la actividad antimicrobiana del bioextracto se evaluó in vitro e in vivo en uvas inoculadas artificialmente. A una concentración del 2% el bioextracto fue capaz de inhibir el crecimiento miceliar de B. cinerea en un 92%. Interesantemente, L. cuneifolia mostró un excelente rendimiento para el control de la podredumbre gris en uvas, demostrando su potencial como alternativa sustentable a los fungicidas sintéticos.Botrytis cinerea is a ubiquitous fungus causing gray mold, the main postharvest disease in fruit, which implies important economic losses in agriculture. With growing concern over health and environmental effects of pesticides, the search for eco-friendly alternatives is a clear priority. Plant extracts represent a rich source of biocompounds with attractive antimicrobial properties. In the last decade, Natural Deep Eutectic Solvents (NADES) has emerged as an auspicious green extraction media to achieve bioextract for a sustainable postharvest control. In the present study, a novel L. cuneifolia NADES-based bioextract was evaluated against B. cinerea. To this purpose, a NADES composed by lactic acid, glucose and water (LGH) was used as extracting agent and compared with traditional solvents in terms of antioxidant capacity and total phenolic content. Furthermore, the bioextract antifungal activity was tested in vitro and also in vivo on artificially inoculated grapes, in order to obtain preliminary data about the efficacy on gray mold development. The antimicrobial activity of the bioextract was assessed using agar diffusion method against B. cinerea, inhibition of 92% was achieved with the bioextract at 2%. Notably, L. cuneifolia bioextract showed an excellent performance for gray mold control on grapes, supporting their potential as alter-native green fungicide.Fil: Boiteux, Joana Jaqueline.

The Influence of Collateral on Capital Requirements in the Brazilian Financial System: an approach through historical average and logistic regression on probability of default
Using data drawn from the Brazilian Central Bank Credit Information System, this paper evaluates the impact of the use of collateral on the probability of default and, consequently, on capital requirement levels in the Brazilian financial system. Literature suggests that the existence of collateral in some credit operations increases the debtor's readiness to honor its commitment and, therefore, could result in a lower probability of default. The methodology used to calculate capital requirements is based on the Basel II IRB-Foundation Approach, although the probabilities of default have been estimated by historical averages following Basel II orientation, and corroborated by a logistic regression model. The test of hypothesis about difference between collateralized and uncollateralized probabilities of default for each risk class indicates that they are statistically different. This result was obtained both from historical average probability of default as from logistic regression model.Sob condições específicas, incluindo o requerimento de capital de 11% adotado no Brasil e a Perda dado Default (ou LGD da sigla em inglês) estabelecida em 45%, este artigo também procura identificar um fator de equivalência da razão entre os requerimentos de capital para risco de crédito na Abordagem Padronizada Simplificada e aqueles calculados pela Abordagem Básica do IRB. Para a amostra utilizada, os resultados indicam que operações de não-varejo com garantia possuem uma probabilidade média de default de 2,46% e um fator de equivalência de 60%. Em contrapartida, operações não garantidas possuem uma probabilidade média de default de 6,66% e um fator de equivalência de 93%, aproximando-se bastante do fator de ponderação de 100% da Abordagem Padronizada Simplificada.
Midiatização e identidade territorial: pressupostos teóricos para a análise das festividades e seus processos de mediação como construtores da identidade territorial no Brasil Meridional
The article aims to understand how mediated processes, used by social actors to mediate relations during the planning and execution of festivities, contribute to the construction of local identity. Mediatization refers to communicative processes guided by technical means and with a collective involvement, which delineate the social phenomena today and build the senses. Territorial Identity is a substrate for building recognition devices, through geographical indications or designations of origin, representing a territory.Objetiva-se compreender como os processos midiatizados, utilizados pelos atores sociais para mediar relações no decorrer do planejamento e execução de festividades, contribuem para a construção da identidade territorial. Midiatização refere-se aos processos comunicativos pautados pelos meios técnicos e com um envolvimento coletivo, os quais delineiam os fenômenos sociais da atualidade e constroem sentidos. Identidade Territorial trata-se de um substrato para a construção de dispositivos de reconhecimento, através de indicações geográficas ou de denominações de origem, que representem um territorio
Participação, representação e representatividade dos povos e comunidades tradicionais nos Conselhos Estaduais de Recursos Hídricos da Amazônia Oriental
This article analyzes the participation, representation, and representativeness of Traditional Peoples and Communities (PCTs) in the State Water Resources Councils (CERHs) of the Eastern Amazon to verify whether such spaces have been the stage for debates, defense of collective interests, and decisions which are relevant to these populations. For this purpose, documental research was carried out regarding the laws, decrees, regulations, resolutions, and minutes published between the years 1997 and 2022 on the websites of the environmental secretariats of the states of Amapá, Maranhão, Mato Grosso, Pará, and Tocantins, resulting in the identification and analysis of 34 terms of office, 23 regulatory decrees, 169 resolutions, 30 minutes, etc. The results obtained indicated that the councils of Amapá, Tocantins, and Maranhão do not have in their decrees the projections of vacancies for PCTs, unlike the councils of Pará and Mato Grosso. Nevertheless, in these councils, the definition of vacancies for representatives of the PCTs was not addressed in 88.89 and 100% of the meetings held, respectively. In the end, it was found that the projections of vacancies for PCTs representatives in the councils do not guarantee effective participation, representation, and representativeness. Therefore, strategies that promote the inclusion and full participation of PCTs in CERHs of the Eastern Amazon are urgently needed.Este artigo apresenta análise da participação, representação e representatividade dos Povos e Comunidades Tradicionais (PCT) nos Conselhos Estaduais de Recursos Hídricos (CERH) da Amazônia Oriental, com o objetivo de verificar se tais espaços têm sido palco de debates, de defesa dos interesses coletivos e de decisões relevantes a essas populações. Para tanto foi realizada pesquisa documental referente às leis, decretos, regimentos, resoluções e atas publicados entre os anos de 1997 e 2022, nos sites das Secretarias de Meio Ambiente dos estados do Amapá, Maranhão, Mato Grosso, Pará e Tocantins, resultando na identificação e análise de 34 mandatos, 23 decretos de regulamentação, 169 resoluções e 93 atas. Os resultados obtidos mostraram que os conselhos do Amapá, Tocantins e Maranhão não possuem em seus decretos a previsão de vagas para os PCT, diferentemente dos conselhos do Pará e do Mato Grosso, em que foi identificada a definição de vagas para os representantes dos PCT, porém estes não estiveram presentes em 88,89 e 100% das reuniões realizadas, respectivamente. Ao fim, constatou-se que a previsão de vagas aos representantes dos PCT nos conselhos não garante a efetiva participação e a representatividade, sendo premente o desenvolvimento de estratégias que possam promover a inclusão e a participação plena dos PCT nos CERH da Amazônia Oriental
