DO LUGAR DAS RELÍQUIAS PARA O LUGAR DA HISTÓRIA: a Biblioteca Nacional e outras instituições de acervo na produção da historiografia brasileira no final do século XIX
Authors: Oliveira Josiane Roza de
Published: January 2022

Resumo A preocupação mobilizada na pesquisa que resultou esse artigo foi identificar como o estatuto do documento se alterou no século XIX para se tornar o centro de novos procedimentos necessários para a elaboração da história moderna no Brasil. As instituições de salvaguarda de acervos documentais, como a Biblioteca Nacional, o Instituto Histórico e Geográfico Brasileiro e o Arquivo Nacional foram os objetos da investigação por meio dos quais pude perceber movimentos específicos que denotaram transformações nas práticas, técnicas e atitudes para com as materialidades do passado. Dentre as instituições, ganhou destaque na análise a atuação da Biblioteca Imperial e Pública - atual Biblioteca Nacional - BN, por ter iniciado sua trajetória institucional no país no início do século XIX como símbolo da realeza portuguesa e, aos poucos, se afirmado como emblema da nova nação independente. A BN se estabeleceu como um lugar importante de salvaguarda de acervos que seriam os mediadores para a elaboração da história do país ao introduzir a organização e a crítica documental como um trabalho profissionalizado indispensável para garantir a autenticidade dos documentos.

RESUMO Objetivo Este estudo visa conhecer o cenário atual da atuação fonoaudiológica em serviços de TAN no Brasil, identificando seus obstáculos e perspectivas, bem como verificar a adequação dos Programas de TAN nacionais aos indicadores de qualidade pré-estabelecidos. Método Estudo observacional analítico, realizado com fonoaudiólogos no exercício da TAN no Brasil, entre agosto de 2018 e agosto de 2019, por meio de um questionário online estruturado. Foram realizadas análises descritivas e correlacionais dos dados no programa SPSS versão 22.0. Resultados A prática efetiva da TAN entre os profissionais não foi condizente, na sua totalidade, com os protocolos oficiais. 48,5% dos fonoaudiólogos afirmaram interrupção da TAN em algum momento nos locais de trabalho, principalmente pela necessidade de reparo do equipamento (64,7%). Quanto aos registros do fluxo e dados de atendimento, que contemplam os indicadores de qualidade, houve maior controle do número total de neonatos que realizaram a TAN (87,9%) e menor controle quanto aos resultados falsos positivos (21,2%). 81,8% dos fonoaudiólogos afirmaram ter disponibilidade para utilizar um sistema para registro e controle de dados da TAN. Conclusão Apesar de as práticas dos profissionais estarem em geral condizentes com protocolos oficiais, a não linearidade do processo e a falta de controle dos dados constituem obstáculos importantes para a qualidade dos serviços de TAN. A maioria dos programas de TAN nacionais apresentados não cumprem os indicadores de qualidade pré-estabelecidos. Considera-se que a informatização dos registros poderá beneficiar os profissionais e potencializar a implementação da TAN como prevista na legislação e políticas públicas nacionais.
A Biblioteca Escolar no Brasil e na Colômbia: análise comparativa de estudos
Authors: Flores Helen Rose , Conte Elaine
Published: January 2022

O trabalho é resultado de uma pesquisa realizada entre 2015 e 2019, com o objetivo de analisar, comparativamente, a questão da biblioteca escolar no Brasil e na Colômbia, a partir do estudo das produções teóricas em ambos os países. Ao partir de inquietações da própria experiência profissional no espaço social da biblioteca, investigamos as semelhanças entre as produções de teses e dissertações que dizem respeito à biblioteca escolar no Brasil e na Colômbia, tecendo, assim, vias de acesso ao intercâmbio das construções teóricas, dos avanços nas leis, nas políticas e nas práticas que vêm se efetivando nestes países. Estruturamos a metodologia com bases hermenêuticas aliada à abordagem comparada, tendo como fonte de pesquisa os repositórios digitais. A hipótese é de que as bibliotecas escolares possam promover novos sentidos ao educar, para ampliar a percepção, bem como a discussão de temas que conduzem  ao  conhecimento  mútuo  dos  respectivos  sistemas  de bibliotecas escolares, que se articulam nos espaços digitais, promovendo a construção de canais formativos para realizar novas pesquisas. Os resultados sugerem que são escassas as discussões que abordam as questões da biblioteca escolar em aproximações interdisciplinares, ou são tratadas apenas por relações pontuais, pela ausência de critérios de análise, ou seja, a dimensão crítica é substituída por uma preferência binária de uma subjetividade anunciada por decretos de governos. Ainda, o panorama encontrado desconsidera aspectos da práxis na conjuntura digital, caracterizando-se como possível lacuna na literatura comparada da área.
OS DESAFIOS PARA A FORMAÇÃO DOCENTE: O CONCEITO DAS COMPETÊNCIAS NA EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA
Authors: Melo Junior Valdenir Cardoso Gomes de , Castaman Ana Sara , Garcia Amélia Maria Lima
Published: January 2022

Esta revisão integrativa de literatura abordou duas temáticas relevantes para a educação profissional e tecnológica (EPT): a lógica das competências e a atual política de formação docente brasileira. O objetivo foi conhecer e caracterizar o conceito das competências, a fim de contribuir para novas investigações, debates e reflexões sobre a temática atrelado à formação docente na EPT. A metodologia pauta-se numa pesquisa de abordagem qualitativa, por meio da revisão integrativa de literatura. Os resultados demostraram que nos últimos 21 (vinte e um) anos, foram selecionados 23 (vinte e três) documento, que relacionam as discussões sobre as competências na formação docente relacionada a EPT permaneceram presentes, mesmo que de modo inconstante no decorrer dos anos. É notável que uma quantidade significativa de autores buscou se aprofundar nessa questão, enquanto um percentual menor reproduziu o conteúdo da legislação brasileira sobre educação e as propostas de documentos de organismos internacionais, sem uma análise crítica. Portanto, as competências são uma realidade que provavelmente não será facilmente superada e deve estar acompanhada de saberes científicos que promovam a cultura, o trabalho, a ciência, a filosofia e o pensamento crítico, por aqueles docentes que querem fazer uma diferença, mesmo com todas as limitações das estruturas de ensino.
Predictors of Major Satisfaction Among Education Students
Authors: HASRET Yılmaz , ŞAHİN BALTACI Hülya
Published: January 2022

The purpose of this study was to examine whether education students' career adaptability, person–major fit, willingness to work in an area related to one’s major and voluntary choice of it are significant predictors of major satisfaction. In this study, Savickas’ career construction theory and Holland’s theory of vocational choice were used. The research was designed according to the correlational model and included 828 students from the education department of a public university. The results of the hierarchical regression analysis showed that the concern, control, and confidence subscales under career adaptability were significant predictors of major satisfaction, but the curiosity subscale was not. In addition, person–major fit, willingness to work in an area related to one’s major in the future, and voluntary choice of one’s major were significant predictors of major satisfaction among the students.

Authors: KOCAYÖRÜK Ercan , TUTKUN Tugay , GÖZÜ Hamide , ŞİMŞEK Ömer Faruk , ALTINTAŞ Emin
Published: January 2022

The current study aimed to explore in the adolescent sample the associations between parenting behaviors (maternal and paternal) and well-being in two countries: France and Turkey. A total of 607 undergraduate university students were recruited with a mean age of 20.85 ± 3.18 years: 283 French and 324 Turkish. The data were administrated by the means of the self-report questionnaires for perceived parenting behaviors (Behavioral control, psychological control, autonomy, and responsiveness) and for well-being by using two indicators: positive and negative affect, and psychological flourishing. Correlation and regression analyses revealed significant associations between parenting behaviors and well-being indicators. First, maternal and paternal psychological control in the Turkish and French groups was associated with negative-affect and this association is higher in the Turkish group than the French group. Moreover, psychological control was associated with a decrease in psychological flourishing only in the Turkish group. Second, maternal and paternal behavioral control was associated with lower negative-affect and higher psychological flourishing in the Turkish group than the French group. In addition, Turkish maternal/paternal responsiveness, as well as autonomy-support, was associated with low negative-affect and paternal autonomy-support was associated with high positive-affect. The implications of the findings for future research are discussed.
Slow Medicine and Choosing Wisely: a synergistic alliance
Authors: Bobbio Marco , Vernero Sandra , Colimberti Domenico , Gardini Andrea
Published: January 2022

Choosing Wisely® is an initiative of the American Board of Internal Medicine Foundation to help physicians and patients engage in conversations about the overuse of tests and procedures and support physician efforts to help patients make smart and effective care choices. Choosing Wisely campaigns are now active and present in 25 countries around the world, on five continents. Italy is the only country where a Choosing Wisely campaign was launched, and it is currently steered by a Nationwide association (Slow Medicine), creating a synergistic alliance. The Slow Medicine Association was founded in 2011 when a group of health professionals and citizens shared a new paradigm of values, methodology, and interventions and decided to establish an association with the mission of working for a health system driven by ethics and quality principles. Three keywords summarize the philosophy of Slow Medicine: measured because it acts with moderation, gradualness, and without waste; respectful because it is attentive to the dignity of individuals recognizing their values; and equitable because it is committed to ensuring appropriate care based on the best available evidence. Slow Medicine allowed the spread of Choosing Wisely in Italy involving several professional societies and participating at the National meetings of the Societies as well as numerous other meetings, in which the mission of the Association is combined with the principle of the ‘do not’ recommendations. Numerous other initiatives were carried out, and new projects were planned in synergy with Choosing Wisely.
Digital learning for disadvantaged students during COVID-19
Authors: Fejes József Balázs , Szűcs Norbert
Published: January 2022

The digital learning instituted in Hungary in the spring of 2020 to halt the spread of the coronavirus there arguably encountered stumbling blocks as regards disadvantaged students. However, we have no information about the details, and mitigating these disadvantages is therefore fraught. The aim of our research is to shed light on the experience of digital learning among disadvantaged students. We analysed responses to an online questionnaire completed by teachers at 48 of Hungary’s after-school programmes (ASPs) who were in contact with over 1000, mostly disadvantaged children. We discussed the questionnaire-based analysis with ten ASP representatives in online workshops. In addition to ICT devices and Internet access, the lack of a learning space is also worth considering in promoting the establishment of objective conditions. In maintaining contact with parents, it is recommended that communication habits that differ from those of the middle class should be taken into account. Developing time management and other skills necessary for independent learning (e.g. reading comprehension, digital literacy) as well as alleviating the psychological burden represent a central task in similar situations. Our recommendations may be of use in the event of future school closures and in terms of facilitating digital learning among disadvantaged students.
Getting married in times of COVID-19 : Structure, agency, and individual decision making
Authors: Balatonyi Judit Flóra
Published: January 2022

Based on my digital anthropological research (nethnography, online surveys, and in-depth interviews) this paper will examine the individual decision-making processes and choices related to getting married during times of COVID-19 in Hungary. The paper raises questions about the extent to which these choices and decisions were individual and reflexive, and how they were influenced or restricted by legal structures and contexts. Using classical and contemporary social theories about decision-making (structuralist and reflexive approaches), on the one hand I aim to explore the structural and contextual circumstances of making decisions about whether to go ahead with, hold-off, modify, postpone, or cancel wedding plans. On the other hand, I study the individual ‘decision horizons’ as well. Through examining discourses surrounding weddings as well as through case studies, I look at how social actors identify and perceive their options and how they perceive and interpret the related structural constraints, contexts, and rules. The results emphasize that despite – or rather in the face of – changing circumstances, many couples sought new opportunities and new means of adapting, but in the meantime they recognized and interpreted the structural constraints that could potentially influence their weddings, maneuvered between them, or just overcame or circumvented them, and at other times sought to create new structures through their individual and community practices.
The economic context of the COVID-19 pandemic in the Mediterranean countries : A comparative analysis
Authors: Urbanovics Anna , Teleki Bálint
Published: January 2022

The COVID-19 pandemic and the related political and economic crisis had serious negative effects on most Mediterranean countries. The paper aims to examine the measures introduced by the governments concerned to ease the crisis both from a quantitative and qualitative perspective. The impact of the activities of similar purpose of the institutions of the European Union are also the focus of the research, with emphasis on the state-aid framework of the European Commission aimed at supporting the economy, and the unfortunate speech of 12 March, 2020 of ECB president Christine Lagarde, which endangered the euro and caused an extreme increase in the sovereign spreads in most of the countries concerned, endangering their banking systems. The main expected results of the research are as follows. Based on the analysis of legislative measures and communications, an evaluation of the relevant actors (governments and EU institutions) will be established. This will be supplemented with the potential implications of the research for future decision-makers concerning how they can learn from how the crisis in these countries was (mis)treated.
Paradoxes of populism during the pandemic
Authors: Brubaker Rogers
Published: January 2022

Populist protests against Coronavirus-related restrictions in the US appear paradoxical in three respects. Populism is generally hostile to expertise, yet it has flourished at a moment when expertise has seemed more indispensable than ever. Populism thrives on crisis and indeed often depends on fabricating a sense of crisis, yet it has accused mainstream politicians and media of overblowing and even inventing the Corona crisis. Populism, finally, is ordinarily protectionist, yet it has turned anti-protectionist during the pandemic and challenged the allegedly overprotective restrictions of the nanny-state. I address each apparent paradox in turn before speculating in conclusion about how populist distrust of expertise, antipathy to government regulation, and skepticism toward elite overprotectiveness may come together – in the context of intersecting medical, economic, political, and epistemic crises – in a potent and potentially dangerous mix.
Resilience against counterterrorism?
Authors: McNeil-Willson Richard
Published: January 2022

This article examines how repression is being wielded by the Russian Federation in Crimea against Muslim Tatar communities under the guise of countering terrorism and violent extremism, and how non-violent resistance and grassroots resilience is being fostered as a means of countering securitisation. The case demonstrates how language developed within a Western security context are co-opted by authoritarian actors, how Islamic activist groups engage in activities that can be framed as ‘resilience-building’ through the language of human rights, freedom of press and democracy, and the issues raised by applying the term ‘resilience’ within a counterterrorism context—both in illiberal and liberal settings. The article finds that techniques comparable to concepts of resilience-building are being conducted in an illiberal setting by communities in response to, and as a counter against highly repressive articulations of counterterrorism. It also suggests that the term ‘resilience’ is problematic in this context, failing to adequately account for—and often actively obscuring—organisational activism of communities and their interaction with the political context. This offers an understanding of community-led responses against counterterrorism and counter-extremism as a tool of repression as well as examining the credibility of terms such as ‘resilience’ within CVE in Crimea and elsewhere.
Roggeband, C. & Krizsán, A. (2021) Politicizing gender and democracy in the context of the Istanbul Convention. Palgrave MacMillan
Authors: Gilby Lynda
Published: January 2022

The Council of Europe Convention on Violence Against Women and Domestic Violence, commonly referred to as ‘the Istanbul Convention,’ came into force in 2014, and is one of the most extensive legal and policy instruments on tackling violence against women (p. 2). However, opposition to the Istanbul Convention has become a focal point of broader opposition to gender equality in the European Union. This book explores the emergence and dynamics of this opposition. It investigates its implications for policies combating violence against women and contributes to scholarship of social movements, particularly their transnational qualities and their interaction with opponents and the state.

(Not) Very Important People: Millennial Fantasies of Mobility in the Age of Excess
Authors: Hopkins Susan
Published: January 2022

In her fascinating but frustrating new book, Very Important People: Status and Beauty in the Global Party Circuit, American sociologist, Ashley Mears (2020) offers both academic and mainstream readers a titillating, cross-over tour around the “cool” nightclub and party scene of the “global elite.” It is perhaps not so much global, however, as American, in the sense of the heteropatriarchal, middle-aged, male, working rich of America (or more precisely of its financial capital New York), jetting into their traditional party hotspots of Miami, Saint-Tropez, or the French Riviera, to party with young women who are (indirectly) paid (in-kind) to pose with them. Whether intentional or unintentional, along the way Mears also offers a dark mirror to the fears and fantasies of a rather lost millennial generation, raised in a new media, image age, which has coupled fast and furious performative excess to old fashioned sexual objectification, in the guise of fun and empowerment for the beautiful people.
Welfare Mediators as Game Changers? Deconstructing Power Asymmetries Between EU Migrants and Welfare Administrators
Authors: Ratzmann Nora , Heindlmaier Anita
Published: January 2022

Under EU law, EU citizens constitute a particular group of immigrants, as they can, mostly without restrictions, move to, and reside in, another EU country, enjoying equal treatment with nationals in terms of accessing employment and social rights. However, as this article demonstrates, the settlement of EU citizens in another member state does not happen without hurdles. Through a careful in‐depth study of access to transnational welfare rights in practice, we analyse knowledge and resulting power asymmetries impacting interactions between certain EU migrant claimants and street‐level bureaucrats in Austrian and German social administrations. Following an inductive approach, based on an extensive data set of 144 qualitative interviews, this article first unpacks the different types of knowledge asymmetries relating to administrative procedures, formal social entitlements and the German language. We then analyse how such knowledge asymmetries may open space for welfare mediation in order to compensate for a lack of German language skills and to clarify misunderstandings about legal entitlements and obligations embedded in the claims system. Finally, our contribution offers a typology of welfare mediators and their characteristics, as not all types can be regarded as equally effective in reshaping power asymmetries. Overall, this article allows for insights into how welfare mediators, as more or less institutionalised opportunity structures, can shift policy outcomes in unexpected ways, enabling access to social benefits and services for otherwise excluded EU migrant citizens working, or seeking to work, in another EU member state.

Published: January 2022

Sideroxol, a kaurene diterpene, was obtained from the acetone extract of Sideritis stricta plant. The ground-state molecular geometry, vibrational frequencies, and NMR chemical shifts were also investigated by using various density functional theories and Pople basis sets. The computed geometries are in good conformity with the experimental data. The comparison between theory and experiments indicates that B3LYP and M06 methods with the 6-31G(d) basis set are able to provide satisfactory results for predicting vibrational and NMR properties. There seems to be no significant effect of addition of diffuse and polarization functions in the basis set used herein.

Design Simulation and Performance Assessment of Improved Channel Estimation for Millimeter Wave Massive MIMO Systems
Authors: Sharma Aditi , Sharma Ashish Kumar , Balai Laxmi Narayan
Published: January 2022

In this paper, we have optimize specificities with the use of massive MIMO in 5 G systems. Massive MIMO uses a large number, low cost and low power antennas at the base stations. These antennas provide benefit such as improved spectrum performance, which allows the base station to serve more users, reduced latency due to reduced fading power consumption and much more. By employing the lens antenna array, beam space MIMO can utilize beam selection to reduce the number of required RF chains in mm Wave massive MIMO systems without obvious performance loss. However, to achieve the capacity-approaching performance, beam selection requires the accurate information of beam space channel of large size, which is challenging, especially when the number of RF chains is limited. To solve this problem, in this paper we propose a reliable support detection (SD)-based channel estimation scheme. In this work we first design an adaptive selecting network for mm-wave massive MIMO systems with lens antenna array, and based on this network, we further formulate the beam space channel estimation problem as a sparse signal recovery problem. Then, by fully utilizing the structural characteristics of the mm-wave beam space channel, we propose a support detection (SD)-based channel estimation scheme with reliable performance and low pilot overhead. Finally, the performance and complexity analyses are provided to prove that the proposed SD-based channel estimation scheme can estimate the support of sparse beam space channel with comparable or higher accuracy than conventional schemes. Simulation results verify that the proposed SD-based channel estimation scheme outperforms conventional schemes and enjoys satisfying accuracy even in the low SNR region as the structural characteristics of beam space channel can be exploited.

Oral Reactive Lesions Associated to Incomplete Removal of Natal Teeth: Case Report
Authors: Cunico Letícia Aparecida , de Meira Caroline Scheliga , Moura Dutra Beatriz Miranda , de Lima Antonio Adilson Soares , de Araujo Melissa Rodrigues
Published: January 2022

Natal teeth are infrequent at birth. Dental extraction is the most recommended treatment to avoid complications. Reactive soft tissue lesions associated to natal tooth or its incomplete removal are rare. A five-month-old female presented natal teeth #71 and #81 which were removed the day after the birth. The baby evolved with two nodules in the region of #71 and #81, pedunculated, 10 and 9 mm, respectively, covered by a pink mucosa, firm in consistency. Periapical radiography showed two radiopaque areas, suggestive of root fragments. After 30 days the nodule located in the region of #81 became purple in color and ulcerated. Both lesions were removed with high intensity diode laser. Histopathological analysis was compatible with inflammatory fibrous hyperplasia (#71) and pyogenic granuloma (#81). Early diagnosis of oral lesions in newborns by means of histopathological examination and a minimum invasive treatment, such as laser surgery, should be of primary concern.

Authors: Hussein Alaa Sabah , Almoudi Manal Mohamed , Abu-Hassan Mohamed Ibrahim , Schroth Robert J , Saripudin Bahruddin , Mohamad Mohd Shawal Firdaus
Published: January 2022

Objective: Several studies have reported that low levels of vitamin D (25(OH)D) are associated with an increased risk of dental caries and that optimal levels may offer protection This study aimed to assess the relationship between serum and saliva 25(OH)D levels and caries among young children.

Study design: A total of 120 healthy children were recruited; 93 with caries and 27 caries-free. Dental caries status was evaluated using decayed, missing and filled in primary teeth (dmft) index. Blood and unstimulated whole saliva samples were collected. Laboratory analysis was performed using Enzyme-Linked Immunosorbent Assay Kit. Data were analyzed with descriptive statistics, bivariate and Spearman’s rank correlation analysis.

Results: There were no significant associations between serum and saliva 25(OH)D levels and caries status (P > 0.05). Levels of 25(OH)D in serum were significantly higher than levels found in saliva (P < 0.05), and a correlation between serum and saliva 25(OH)D levels was observed (P < 0.05).

Conclusions: The association between serum and saliva 25(OH)D and dental caries in young children was inconclusive. However, a positive and significant correlation was observed between serum and saliva 25(OH)D levels. Further studies are warranted to investigate the definite relation between 25(OH)D levels and dental caries and using saliva 25(OH)D as a non-invasive alternative method over blood samples.
The Right to Repair Goods in the Era of Digitalization and Globalization
Authors: Likhter P. L.
Published: January 2022

Today, large companies are increasingly using controversial strategies related to the violation of the buyer’s rights to repair the goods both during and after the expiration of the warranty period. This is primarily manifested in the restriction of access to the necessary information on the product repairing, hindering the work of independent service organizations, intentional complication of parts during their design, unreasonably high degree of integration of units, lack of a sufficient number of spare parts on the market, etc. As a rule, such actions distort the principles of integrity and transparency, which, in turn, entails risks to consumer and environmental safety. This issue is of particular relevance in the context of the COVID-19 pandemic, when sellers of medical equipment restrict the possibility of its restoration by independent specialists, and also prevent the distribution of the necessary software. Based on the results of the work, it is concluded that it is advisable to establish boundaries for the conduct of market participants to stimulate the production of durable and maintainable goods in order to transit to a circular economy.

A case of children's diplegia complicated by bilateral athetosis
Authors: Osokin N. E.

The comparative rarity of bilateral cerebral spastic palsy, a disease characteristic, as you know, exclusively of childhood, with the incompleteness of the modern doctrine of spastic diseases in general, prompts me to describe a case that I had recently observed in Pozdeevskaya Children's Hospital. This case is also of interest because of the extremely peculiar phenomena of hyperkinesis in the form of athetosis, noted in it, the origin of which, despite all the efforts spent so far by many, has not been clarified far enough.

The article addresses the issues of the modern development of judicial forms in relation to appellate proceedings in criminal proceedings in a systematic manner and in connection with the development and formation of cassation proceedings, as well as the exceptional procedures for review – judicial supervision and consideration of cases in newly discovered circumstances. This approach has not yet been developed and in terms of the systemic approach has some ambiguities and imperfections. At the same time, this use of almost all the main forms of judicial review takes place in Russia for the first time and needs in-depth analysis. In turn, the appellate procedure for judicial activity in the criminal process has reached a new level, it has significantly expanded and strengthened. A special judicial unit has been established in the judicial system, five appellate courts, which, in the light of the improvement of the procedural procedure for reviewing an appeal, significantly changes its position in the criminal justice system, due, in particular, to the properties of freedom of appeal and appellate validity of decisions and actions.

The article analyses the current level of development of the topic of "green" public procurement both in Russian legal acts and in domestic scientific literature. The authors conducted a categorical analysis of the term "green" public procurement, based on which the definition recommended for use in the Russian system was derived. The analysis of international experience in the implementation and development of green procurement was followed by a description of the specifics of legal regulation in several countries. By means of an electronic questionnaire survey of contracting system entities, the current level of application of environmental criteria in procurement was empirically assessed and the attitudes of Russian customers and suppliers towards the introduction of new environmental requirements in procurement legislation were identified. Thus, customers are not motivated to use "green" criteria, as they are not aware of them and their application may be regarded by regulatory authorities as a restriction of competition, and suppliers are not interested in producing such products, since they will not be competitive due to the high price. Based on the results obtained, recommendations were developed for the gradual, step-by-step incorporation of norms and practices related to the greening of the procurement process into the contract system.

Resumo O foco deste texto, recorte de uma pesquisa mais ampla sobre alfabetização de crianças, é a educação literária no contexto escolar. O objetivo é abordar como duas docentes, colaboradoras da pesquisa e atuantes em uma turma de 2º ano da Rede Municipal de Recife, conduziram as mediações durante a leitura de livros literários, além de evidenciar e compreender as diferenças e semelhanças nessas mediações, revelando o processo de escolarização da literatura. Metodologicamente, trabalham-se com técnicas e ferramentas etnográficas, incluindo a observação participante e entrevistas; a categoria de análise central é o evento. Argumenta-se que as interações com o livro literário, mediadas por professores, precisam ocupar um lugar de destaque nos processos de alfabetização. Os resultados obtidos indicam que, nessa turma, esses ocuparam esse lugar, mas também apontam contrastes entre as formas de mediação do texto literário, que podem resultar em aprendizagens também diferentes para as crianças; além disso, deixam claro o processo inevitável de escolarização da literatura, com as marcas da cultura escolar, próprias do trabalho pedagógico com a alfabetização.

AbstractThe focus of this text, part of a broader research on children's literacy, is literary education in the school context. The objective is to address how two teachers, research collaborators and working in a 2nd year class, from the Municipal Network of Recife, conducted mediations while reading literary books, in addition to highlighting and understanding the differences and similarities in these mediations, revealing the literature schooling process. Methodologically, it is worked with ethnographic techniques and tools, including participant observation and interviews; the central analysis category of this study is the event. It is argued that interactions with the literary book, mediated by teachers, need to occupy a prominent place in literacy processes. The results obtained indicate that, in this class, they occupied this place, but also point out contrasts among the forms of the literary text mediation, which can result in different learning for children; in addition, they make clear the inevitable schooling literature process, with the marks of school culture, typical of pedagogical work with literacy.
