Language establishes itself as one of the oldest branches - since Ancient Greece -  of systematic investigation. Thus, it is important to emphasize that language is a frequent object of academic analysis in both the social sciences and the exact sciences, but without a consensual understanding of its "nature". The debate focuses mainly on how language emerges in the species and its relation to human thought. So, we analyze two of the main currents of thought that have undertaken linguistic studies with respect to this issue, such as 1. The school of linguistic relativity; and 2. The school of linguistic universalism. For this purpose, it was fundamental to conduct a bibliographic research - in journals, theses and books - which allowed us to grasp the theoretical approach of both schools. Thereby, throughout this article, we seek to understand the different approaches to the relationship between language and thought, in such a way that we  conduct a general analysis of relativism and then address linguistic universalism. Therefore, the debate about language and its relation with thought is establishes as one of the most relevant elements in the history of human society.

Socio-economic systems worldwide suffer effects due to issues of capitalism, generating inequality gaps; Faced with these events, the associative Popular and Solidarity Economies (EPS) is a key tool for the sustainability of enterprises; same that reached relevance in the quarantine and states of exception (COVID-19), a large part of people had shortages before the closure of the commercial chains, the entrepreneurs, assuming risks and possible contagion, made possible the supply, of food, medicines and other products to homes. However, as the large stores began to open to the public, many businesses were disappearing. The present aims to analyze the key factors in the sustainability of enterprises, applying a methodology with a social hermeneutic approach, to analyze the behavior of entrepreneurs in the face of challenges, maintain a decent and supportive job. The results and discussion determine that associativity with innovative capacity, good governance, and social commitment, create sustainable business models and levels of competitiveness. Therefore, transformational leadership behaviors must coexist in cooperative and community enterprises, in order to adequately generate trade and fair prices. The current rulers, based on optimal social equity, must distribute resources so that the most disadvantaged sectors have the same opportunities for a healthy, productive life

American trypanosomiasis, known as Chagas disease, is a potentially fatal disease caused by the unicellular flagellated protozoan Trypanosoma cruzi, and its intermediate host is the hematophagous insect named the triatomine. In Brazil, 10 genera of triatomines are of epidemiological importance for the disease. Because of the preventive measures and epidemiological monitoring, this study aimed to verify the triatomine species in the municipality of Santana do Ipanema, belonging to the state of Alagoas, since there is no data in the literature with such information. For this, a cross-sectional descriptive study was conducted with data from the secretariat of the municipality of Santana do Ipanema to verify the species of captured and positive triatomines, between the years 2016 and 2020. During the study period, a total of 405 triatomines collected in the municipality were recorded, and three species were identified. It was observed that most of the collections occurred in the rural area of the municipality with almost 15 times more collections than in the urban area; however, the highest rate of positivity occurred in the urban area. The most common triatomine found in the municipality studied was Rhodnius domesticus, while Triatoma brasiliensis obtained more positive specimens. Although there are no confirmed cases of Chagas disease in the population of Santana do Ipanema, it was found that there is the presence of vectors that transmit Chagas disease and positive vectors for Trypanosoma cruzi. Therefore, our study suggests that entomological surveillance should be more present and continuous in both areas of the municipality for the effective control of Chagas disease

Star fruit (Averrhoa carambola L.) is an exotic fruit originating in Southeast Asia and has seeds with low germination. The objective was to evaluate the effect of gibberellin on the emergence and initial development of star fruit seedlings. The seeds were removed from the fruits and washed in running water, and placed in gibberellin solution 1,000 mg.L-1, 2,000 mg.L-1, 3,000 mg.L-1, 4,000 mg.L-1 and pure water as a control. for 30 minutes. Sowing was carried out by placing 1 seeds per 280 mL tube in a substrate containing ravine soil + tanned manure (3:1) in a randomized block experimental design. Thirty days after the emergence of the first seedling, the percentage of emergence, emergence speed index and mean emergence time were evaluated. Ninety days after the emergence of the first seedling, the seedling height, collar diameter, number of leaves, root length were evaluated; green and dry mass of the leaves, green and dry mass of the roots. The star fruit seed has a low percentage of germination, with low emergence rates, and the use of gibberellin was efficient to increase and accelerate emergence, showing a positive response to the variables plant height, number of leaves, stem diameter and length of the seed. source. The treatment with gibberellic acid had a positive effect on the emergence and development of star fruit seedlings, and on the mass production of leaves and roots, with the concentration of 1,000 mg.L-1 showing the best results.

The research aims to identify social representations of digital technologies of information and communication, shared by pedagogy graduates, permeated by the context of the pandemic in their initial formation. For its cognitive and subjective character, the theoretical field that supports this study is the Social Representation Theory. The methodology of this research has a qualitative character, using the Technique of Free Association of Hierarchical Words (ABRIC, 2005), a strategy which conditions the respondents to a hierarchy of the terms based on their importance in the representation of this group. The results showed the internet, computer, cellphone and innovation as possible components of the core of the social representation shared by the group of students; while the difficulty, learning, distance learning, adaptation, education, resource, access, conection, tools, google meet, google classroom, challenge and inequality figure in the periphery field of this representation. In addition, the production of these social representations would be associated with moments of tension, little connection with technologies, distance and social inequality.

This article aims to analyze the specificities of the construction of algebraic thinking by deaf students in the early and final years of elementary school through a Systematic Review. The specific objectives are: to identify the curricular recommendations - National Common Curricular Base (2017) and Pernambuco Curriculum (2019) related to the construction of algebraic thinking by elementary school students; to retrieve from the CAPES Periodicals Portal, Brazilian Digital Library of Theses (BDTD) and Google Scholar research that deals with the construction of algebraic thinking or the learning of mathematical knowledge by deaf students; to point out the recommendations of the literature on the development of algebraic thinking by deaf elementary school students. The study was guided by a systematic literature review methodology based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), which started with searches for articles and dissertations in the CAPES Periodicals Portal, BDTD and Google Scholar databases. A total of 2 727 studies were identified. After applying the inclusion or exclusion criteria, nine studies were selected for review. The results indicated that deaf students, like hearing students, present particularities in the construction of mathematical knowledge, especially in the Algebraic Unit Theme.

A dislexia é um dos mais importantes transtornos de aprendizagem. É caracterizada por dificuldade de linguagem verbal, escrita e compreensiva. Seus primeiros sinais surgem no início da vida e vão aumentando quando o sujeito entra a vida escolar.  Por causa das limitações de todos os envolvidos no processo de ensino aprendizagem, no passado muitos disléxicos se evadiam a escola. E aqueles que avançavam na escolaridade não eram diagnosticados na idade escolar. Aliás, muitos disléxicos só foram diagnosticados ou autodiagnosticados na idade adulta, não recebendo apoio intelectual durante a sua formação acadêmica. Visando revelar elementos da dislexia ao longo de uma vida, neste artigo tomaremos a história de vida de uma pedagoga. Destacaremos seu percurso acadêmico e sua trajetória existencial. Mostraremos a importância da discussão acerca da dislexia, entendendo sua implicação para a vida de um grupo numeroso de pessoas. A partir do caso, enfatizaremos ser possível uma pessoa disléxica aprender, avançar e ter sucesso profissional.

The covid-19 disease, caused by the SARS-CoV-2 virus, forced the transformation of face-to-face to virtual teaching in educational institutions around the world. This is because this virus has a high potential for contagion and can cause very serious infection. This problem was associated with the lack of any effective treatment or vaccine to combat the virus and, therefore, the solution was social isolation, which in education, brought the remote mode of teaching to continue the teaching-learning process. The purpose of this review is to provide the reader with an overview of the impacts of the covid-19 pandemic on basic and higher education. Of course, making use of distance education was the best way out to not cancel the educational process for a time, until then, indefinitely, but some weaknesses and consequences emerged. For example, unequal access to an Internet connection, which results in an unequal distribution of resources and strategies, mainly affecting low-income or more vulnerable people. This crisis offers an unprecedented opportunity for the State to manage by planning effective and safe ways to act in atypical and calamitous situations.

  Currently, there is an enormous need and search for healthy food, as well as means of agricultural production that are less harmful to biodiversity. Family farming is a form of agricultural production based on family reproduction and is responsible for the production of most of the food consumed by the Brazilian population, since it is not aimed at the production of commodities. In this sense, these social analytical categories also aim at a production with more sustainable and fair guidelines. In this sense, the objective of this study was to discuss the vulnerabilities and problems faced by family farming. Through this immersion it is possible to understand that there are still needs to be faced, especially to the detriment of public policies and social education.

The use of medicinal plants for therapeutic purposes to treat various diseases is one of the first resources used by humanity, due to the existence of several plants with numerous therapeutic purposes. The present work intends to cover, in an integrative review, the use of Mikania glomerata, aiming to evaluate its potential in the treatment of respiratory allergy, in which the immunological mechanism involved is mediated by antibodies of the IgE class, and the main Factors that aggravate the allergic picture are called allergens, such as house dust, pet dander, mold and pollen. As for the research approach, it will be qualitative type. Data collection was carried out using the main database platforms such as SciELO, LILACS, MEDLINE, Virtual Health Library (BVS) and the academic search engine Google Scholar. The population and the sample will be the works found in these databases, where the data will be analyzed in a qualitative way. The search in the databases chosen for the present work resulted in 188 articles, after applying the filter, 9 articles were selected for the research, thus being able to confirm the benefits of using M. glomerata for the treatment of allergic diseases that affect the respiratory system. Studies on the side effects of herbal medicines based on the plant in question, or on toxicity, are quite scarce. Leaving evident the need for expansion of studies in order to evaluate the toxicity and side effects of the plant.
