title: Professional retention policies for teachers in the Northeast Region: implementation, turnover and regularity

description: ABSTRACT This article is the result of a post-doctoral research that had as its object of analysis the policies of professional retention of teachers in the Northeast Region of Brazil. These are policies implemented as an action to combat the turnover or absence of teachers in schools located in territories of high social vulnerability or in contexts of difficult access. The main strategy of these policies is the payment of salary bonuses conditioned to the permanence of teachers in these schools. This research aims to identify the context of emergence and implementation of these educational policies in order to better understand them. It considers the effects produced on the indicators of turnover, absence of teachers, as well as those referring to the regularity of the teaching staff. The methodological approach, of a qualitative nature, went through the stages of literature review, document research and data collection from the survey answered by the principals of Prova Brasil, and the indicators of regularity of the teaching staff. The theoretical framework is based on the academic production that problematizes the relationship between education, poverty, and their effects on the teaching work. The analyzes showed that this policy format presents weaknesses by focusing only on the teaching dimension and on the financial bonuses as a reference to face educational inequalities resulting from the lack of teachers.

title: Tax Compliance in the Wild: Critical Review of Nudging and Proposition of an Integrative Framework

description: ABSTRACT Context: There is an inflation of behavioral frameworks applied to social problems, such as tax dodging. There has been also a surge in the creation of the so-called nudge units throughout the world, following the success of the pioneer units in USA and UK. Meanwhile, there has been criticism directed at aspects such as ‘psychologism,’ paternalism, and short-termism associated with nudge approaches. Moreover, by ignoring systems thinking, complexity science and other broader approaches, nudging may lead to interventions that can be ineffective or counterproductive in the long term. Goal: To overcome such limitations, the paper proposes an integrative framework, the Nested Circles Model, which put the intended behaviors in a perspective ranging from microworlds to broader upstream influences. Method: The paper employs a qualitative approach to critically review the literature on nudging and map its shortcomings. Results and contributions: The proposed model integrates major concepts from popular behavioral frameworks and incorporates elements that influence the repertoire of behaviors adopted by individuals, including intangible stocks (trust and fairness) and complexity markers. The paper concludes by exemplifying the application of the Nested Circles Model to three problems in the context of taxation in Brazil.

title: SEX EDUCATION: AN ANALYSIS OF BRAZILIAN LEGISLATION AND OFFICIAL DOCUMENTS IN DIFFERENT POLITICAL CONTEXTS

description: ABSTRACT: The provision of Sexuality Education in schools can significantly contribute to the reduction of violence motivated by issues related to gender and sexuality. This Sexuality Education needs to go beyond purely biological issues, addressing several other themes, such as body, pleasure, consent, and violence in addition to more obvious issues of gender, sexuality and diversity. However, in order to carry it out, teachers need to have the support of official documents and legislation. This research aims to verify how issues concerning Sexuality Education, gender and sexuality appear in laws, decrees and other publications that guide Brazilian Education as well as to relate them to the socio-political contexts in which they were published. To achieve our goal, we searched for these documents, covering the period from 1990 to 2018, and we focused our analysis on twenty-eight of them. The analysis showed that, in fact, the legislation not only allows, but determines that Sexuality Education be in schools. However, different political contexts have a great impact on the way in which Sexuality Education appears in the documents, sometimes explicitly, sometimes subjectively and diluted in the discourse of diversity and recently, completely silenced. In addition, recurrent cycles of advances and setbacks in different political contexts since re-democratization have culminated in gaps and discontinuities in Sexuality Education policies, impeding the development of a specific law on the subject and preventing its consolidation within Brazilian schools.

title: Lived experiences of babies in an Early Childhood Center in Belo Horizonte

description: ABSTRACT This article analyzes the lived experiences of a group of babies in a collective context of education and care. Based on the dialogue between Cultural-Historical Theory and Ethnography in Education, we followed a group of 13 babies, aged between 10 months to 1 year and 2 months, for six months, seeking to understand their experiences in this context. The empirical material was built through filmic and photographic records, fieldnotes and semi-structured interviews with adults. The babies approached each other provoked by physical touch, cultural artifacts and initial play in the infant’s room. We argue that approaching each other can be understood as the movement performed by babies, constituting a semantic field through the lived experiences in that context and enabling the relationship between them. In this context, a representative history of the lived experiences constituted in the infant’s room was selected, which revealed acts of care through which two babies, Ícaro and Giulia, initiated and sustained their relationships in the educational space. The analyzes reveal (i) the attractive force of cultural artifacts; (ii) the diversity of activities listed in the nursery routine; (ii) the great value in the relationship with the teachers; (iii) the fleeting nature of babies’ interactive dynamics.

title: Dietary polymer-coated urea enhances the goats lactational performance, excretion of microbial purine derivatives and blood metabolites in the semi-arid zone of Iran

description: ABSTRACT. This study aimed to determine the effect of using different sources of nitrogen to supply part of degradable intake protein needs in lactating goat performance and its effect on excretion of microbial purine derivatives and blood metabolites. Thirty-two lactating Saanen goats (body weight 38.85 ± 2.14 kg and 1979 ± 0.25 g day-1 milk yield) were used in a one-way ANOVA completely randomized design. Goats were assigned to the following treatments for a 10-wk experimental period: 1) Control (canola meal as a nitrogen source); 2) Urea (0.5% urea); 3) Optigen (0.55% Optigen- Alltech. Inc., Lexington, KY) and 4) Polymer-Coated Urea (PCU- international patent number: A01K5/00, 0.7% PCU) based on dry mater intake. Non-protein nitrogen groups had a comparative effect (p &gt; 0.05) between control and other treatments on milk composition, microbial protein synthesis and they affected on blood factors including urea, cholesterol, and ALT. Dry matter intake decreased (p &gt; 0.05) in PCU, Optigen, Urea than Control goats. Synthesis of microbial protein in PCU goats was 22.5 g day-1 and it was greater (p &gt; 0.05) than other treatments. Plasma cholesterol was increased in PCU and Optigen, whereas urea concentration was increased in Urea and Control goats. Milk production was higher in PCU than Urea and Control. Feed conversion ratio was improved (p &gt; 0.05) in PCU and Optigen goats versus other treatments. This study demonstrated that polymer-coated urea can be utilized as a nitrogen source and improve goats milk performance.

title: Sobre a interpretação econômica da história em Gilberto Freyre (1933-1956)

description: ABSTRACT This article aims to analyze the relationship between economics and history in the work of Gilberto Freyre, particularly in The Masters and the Slaves and The Mansions and the Shanties. During his studies at Columbia University in the 1920s, the author came into contact with the American New History. Similar to the Annales movement in France, it proposed a new way of thinking History, different from 19th century historiography, which claimed to be scientific in the same sense of any other science. Influenced by Barnes and Seligman, both his professors at Columbia, Gilberto Freyre conceived Brazilian social formation as based on the patriarchy, a category he used as a criterion of periodization. The development and decay of rural patriarchy were analyzed from the viewpoint of its materiality - architectural forms, food diets, clothing, furniture, ecology - making for a very unique vision of Brazilian history, understood by Freyre as an economic interpretation of history.

title: Selection parameters for improvement of yield and quality in tomatillo

description: ABSTRACT The extended use of the same variety by farmers over successive generations and reuse of the “seeds” caused natural variability that can be a magnificent opportunity for genetic improvement of tomatillo. Two successive seasons were accomplished to select genotypes with good performance from a heterogeneous population of the local tomatillo “Balady”. The results revealed significant differences in early yield as fruit number and average fruit weight over the original population. Additionally, the results revealed a highly significant correlation between fruit set percentage and total soluble solids (TSS) at 60 days and the marketable yield with fruit length and TSS at 60 days. In conclusion, the path analysis along with heritability and selection genetic gain showed that early yield and fruit set are the two most critical component traits for fruit yield in tomatillo. In addition, the average fruit weight showed a low indirect effect on fruit yield per plant. Twenty promising genotypes were selected as a kernel for pure line development through further breeding programs.

title: Trinta anos da Convenção do Clima

description: ABSTRACT In this paper, we review briefly the commitments made by the signatories of the CONVENTION ON CLIMATE CHANGE since 1992, which led to the PARIS AGREEMENT where there are no mandatory goals for reducing greenhouse gases, as those of the 1997 KYOTO PROTOCOL. In addition, an analysis is made of the evolution of the CO2 emissions showing that substantive reductions were achieved by the European Union and the United States through the adoption of energy efficiency measures, unlike other countries. The average annual investment in these activities for 2011-2019 was $480 billion, but only 16% are concessional funds and the remaining are loans and investments. As for the transfer of funds from industrialized to developing countries, the amount was approximately $83 billion per year less than the target of $100 billion accorded at COP15 in Copenhagen, a small part in concessional terms. At COP27 in Sharm-el-Sheik, Egypt, in 2022, little progress was made to limit global warming to 1.5 ºC by 2050, except the creation a new FUND to help more vulnerable countries face the consequences of global warming.
