Effects of nitrogen and phosphorus availability on the early growth of two congeneric pairs of savanna and forest species
Authors: Paganeli B. , Batalha M. A.
Published: June 2021

Abstract In the tropical region, savannas and seasonal forests, both highly diverse biomes, occur side by side, under the same climate. If so, that mosaic cannot be explained solely by climatic variables, but also by fire, water availability and soil status. Nutrient availability in the soil, especially nitrogen and phosphorus, has been postulated to explain the abrupt transitions between savannas and seasonal forests in tropical regions. Plants from these two biomes may present different nutritional strategies to cope with nitrogen and phosphorus limitation. We used two congeneric pairs of trees — each pair with a species from the savanna and another from the neighboring seasonal forest — to test whether savanna and forest species presented different nutritional strategies during their early development. We cultivated 56 individuals from each of these species in a hydroponics system with four treatments: (1) complete Hoagland solution, (2) Hoagland solution without nitrogen, (3) Hoagland solution without phosphorus, and (4) Hoagland solution without nitrogen and phosphorus. After 45 days, we harvested the plants and measured total biomass, root to shoot ratio, height, leaf area, and specific leaf area. Overall, savanna species were lighter, shorter, with smaller leaves, higher specific leaf areas, and higher root to shoot ratios when compared to the forest species. Nitrogen increased the performance of species from both biomes. Phosphorus improved the performance of the forest species and caused toxicity symptoms in the savanna species. Hence, savanna and forest species presented different demands and were partially distinct already as seedlings concerning their nutritional strategies.

Abstract Artemisia absinthium L. is an important herb that is widely cultivated in different parts of the world for its medicinal properties. The present study evaluated the effects of four concentrations of nanoparticles treatment (0, 10, 20 and 30 mg L-1) and NaCl salinity stress (0, 50, 100 and 150 mM NaCl) and their interactions with respect to the expression of two key genes, i.e. DBR2 and ADS, in the biosynthesis pathway of artemisinin in A. absinthium. Total RNA was extracted and a relative gene expression analysis was carried out using Real-Time PCR. The amount of artemisinin was also determined by HPLC. All the experiments were performed as factorial in a completely randomized design in three replications. The results revealed that salinity stress and nanoparticles treatment and their interaction affected the expressions of these genes significantly. The highest levels of ADS gene expression were observed in the 30 mg L-1 nanoparticles–treated plants in the presence of 150 mM salinity stress and the lowest levels in the 10 mg L-1 nanoparticles–treated plants under 50 mM salinity stress. The maximum DBR2 gene expression was recorded in the 10 mg L-1 nanoparticles–treated plants in the absence of salinity stress and the minimum expression in the 100 mM salinity-stressed plants in the absence of nanoparticles treatment. Moreover, the smallest amounts of artemisinin were observed in the 150 mM salinity-stressed plants in the absence of nanoparticles and the highest amounts in the 30 mg L-1 nanoparticles–treated plants. The maximum amounts of artemisinin and ADS gene expression were reported from the plants in the same nanoparticles treatment and salinity stress conditions. In this regard, the amount of artemisinin was decreased by half in the plants containing the highest DBR2 gene expression. Meanwhile, no significant correlation was observed between these gene expressions and the artemisinin amount in the other nanoparticles–treated plants under different levels of salinity stress. The biosynthetic pathway of secondary metabolites appears to be very complex and dose not directly dependent on these gene expressions.

Abstract This study goal to evaluate the effects of different concentrations of lead (Pb) and silver (Ag) on germination, initial growth and anatomical alterations of Lactuca sativa L. Plants use various mechanisms to reduce the impacts caused by anthropic action, such as xenobiotic elements of soils and water contaminated by heavy metals. These metals were supplied as lead nitrate and silver nitrate and the following treatments were established: control for both metals, maximum dose of heavy metals, for arable soils, allowed by the National Council of the Environment (Ag = 25 mg. Kg-1, Pb = 180 mg. Kg-1), double (Ag = 50 mg. Kg-1, Pb = 360 mg. Kg-1) and triple (Ag = 75 mg. Kg-1, Pb = 540 mg. Kg -1) of this dosage. Vigor and germination tests of the seeds and possible anatomical changes in the leaves and roots of lettuce plants were performed. The species showed a high capacity to germinate under Pb and Ag stress, and the germination was never completely inhibited; however, the germination decreased with increasing Pb concentrations, but not under Ag stress. The use of increasing doses of metals reduced seed vigor and increased chlorophyll content. An increase in biomass was also observed in plants from treatments submitted to Pb. The phytotoxic effects of metals were more pronounced at 15 days after sowing. Anatomically, L. sativa was influenced by metal concentrations, and had a reduction of up to 79.9% in root epidermis thickness at the highest Pb concentration, although some structures did not suffer significant changes. The results suggest that L. sativa presents tolerance to high concentrations of heavy metals, showing possible mechanisms to overcome the stress caused by these metals. In this research lettuce possibly used the mechanism of exclusion of metals retaining Pb and Ag in the roots preserving the photosynthetic apparatus in the aerial part of the plants. In general, the chemical element Pb was more toxic than Ag, in these experimental conditions.

Abstract Scorpionic accidents are a major public health problem due to the high occurrence with potential seriousness. In this manner, the research aimed to analyze the occurrence of scorpionic accidents in a municipality in the northeastern of Brazil. An exploratory, descriptive study was made, with a quantitative approach, using secondary data which was gotten from the Notifiable Diseases Information System (SINAN), from 2008 to 2018. Data such as neighborhood, presence of street markets were also used, and the existence of sanitation and climatic data such as temperature and season. Geoprocessing was used to identify possible changes in the environment. In the analyzed period, 9,330 cases of scorpion accidents were recorded, with an average of 848 annual notifications. Scorpionic accidents occurred more frequently in women (5,686; 60.94%). Individuals aged 20 to 29 years (1.727; 18.51%) were more frequent to scorpion stings. Regarding the body parts where the stings were made, the highlights were on the foot (3.515; 37.67%) followed by the hand (2.818; 30.20%). No statistically significant relation was observed between climatic factors and scorpionic accidents. However, the high number of cases of scorpionic accidents was observed in the last 11 years studied. It was evident that during the study period there was no statistical relationship when climatic factors were correlated to scorpionic accidents. On its turn, when it was verified the results of the geoprocessing analysis, it was seen that anthropic factors have been motivating the potentiation of the occurrence of these accidents.

Abstract Alpha amylase, catalyzing the hydrolysis of starch is a ubiquitous enzyme with tremendous industrial applications. A 1698 bp gene coding for 565 amino acid amylase was PCR amplified from Geobacillus thermodenitrificans DSM-465, cloned in pET21a (+) plasmid, expressed in BL21 (DE3) strain of E. coli and characterized. The recombinant enzyme exhibited molecular weight of 63 kDa, optimum pH 8, optimum temperature 70°C, and KM value of 157.7µM. On pilot scale, the purified enzyme efficiently removed up to 95% starch from the cotton fabric indicating its desizing ability at high temperature. 3D model of enzyme built by Raptor-X and validated by Ramachandran plot appeared as a monomer having 31% α-helices, 15% β-sheets, and 52% loops. Docking studies have shown the best binding affinity of enzyme with amylopectin (∆G -10.59). According to our results, Asp 232, Glu274, Arg448, Glu385, Asp34, Asn276, and Arg175 constitute the potential active site of enzyme.

Abstract Wood-boring beetles develop in live trees and dead wood, performing ecological services such as decomposition and regulation of forest resources. Species of the Cerambycidae family, widely distributed in the world, bore into the trunks of trees and dead wood in native and cultivated areas. The objective is to report the first host plant for Thoracibidion lineatocolle (Thomson, 1865) (Coleoptera: Cerambycidae) and a new host plant for Temnopis megacephala (Germar, 1824) (Coleoptera: Cerambycidae) in the Brazilian Atlantic Forest biome. Three logs, with one-meter-long by 20 cm in diameter, were cut from the trunk of a healthy Anadenanthera colubrina (Fabaceae) tree in October 2013 and tied in the understory at 1.5m high in the Rio Doce State Park, Minas Gerais State, Brazil. The logs, exposed in the forest, were each removed after 40, 80 and 120 days and stored individually in a cardboard box in the “Laboratório de Campo do Projeto de Ecologia de Longa Duração (PELD-CNPq)” in the Rio Doce State Park. A total of 94 individuals of T. lineatocolle and 228 of T. megacephala emerged from the A. colubrina logs. This is the first report of a host plant for T. lineatocolle and a new host plant for T. megacephala.
Preocupación por el cambio climático, condiciones económicas individuales y priorización del medioambiente en América Latina
Authors: Armesto Alejandra
Published: June 2021

Los ciudadanos de América Latina se preocupan por las consecuencias del cambio climático más que los de cualquier otra región del mundo. Sin embargo, esta preocupación no siempre conduce a la priorización del medioambiente sobre el crecimiento económico. Este artículo argumenta que los constreñimientos económicos de los individuos condicionan la relación entre sus creencias acerca de la gravedad de las consecuencias del cambio climático y sus preferencias frente al dilema entre priorizar el medioambiente o el crecimiento económico. El análisis de encuestas del Barómetro de las Américas (Lapop) de 2016 en 18 países de América Latina, con modelos jerárquicos lineales y ecuaciones estructurales generalizadas, muestra que las creencias acerca de la seriedad de las consecuencias del cambio climático tienen un efecto positivo y significativo sobre la priorización del medioambiente entre los individuos con una riqueza patrimonial por encima de la media y un efecto negativo entre los individuos con riqueza patrimonial por debajo de la media. Este artículo hace dos contribuciones. Primero, el estudio analiza el efecto condicionado de la preocupación por el cambio climático sobre la priorización del medioambiente dependiendo de los constreñimientos económicos individuales. En segundo lugar, aporta a la investigación acerca de las actitudes medioambientales en América Latina.

Authors: Côrtes Pâmela de Rezende , Oliveira André Matos de Almeida
Published: June 2021

O objetivo deste artigo é saber se, entre julho de 2013, período imediatamente posterior às Jornadas de Junho, e junho de 2017, no Brasil, houve movimentos com retórica anti-establishment buscando tornarem-se partidos políticos. A avaliação foi empírico-descritiva, usando os programas dos movimentos. Para conceituar a retórica de um movimento como anti-establishment político, foram utilizados os três critérios de Abedi (2004). Concluímos que havia, no Brasil, no período estudado, partidos em formação que possuíam retórica anti-establishment político. O artigo pode contribuir tanto para o estudo da retórica anti-establishment político no Brasil quanto para o estudo dos partidos políticos em formação, um objeto que recebe pouca atenção acadêmica.
Partidos, governo e Legislativo nas disputas do Orçamento Participativo: uma análise comparativa
Authors: Souza Luciana Andressa Martins de
Published: June 2021

Este artigo amplia a discussão acerca das disputas entre o Orçamento Participativo (OP), os partidos e os atores políticos locais, ao apresentar uma análise sistemática e diacrônica dos impactos da composição de forças dos partidos governistas e oposicionistas, delineadas no âmbito da arena eleitoral, sobre a adoção, durabilidade, interrupção e o fim dessa inovação democrática, assim como sobre os seus distintos graus de institucionalização. Para tanto, analisamos três pares contrafactuais de municípios com características majoritariamente semelhantes, a saber: São Carlos e Piracicaba; Rio Claro e Leme; Matão e Sertãozinho. Esses pares se diferenciam pelo partido que esteve à frente da iniciativa do OP (PT e outros partidos). Os resultados revelam um universo pouco explorado e passível de ser replicado em outros contextos, contribuindo tanto para a ampliação do debate acerca do papel do Legislativo no grau de institucionalização de instituições participativas quanto para o aprimoramento dessa agenda de pesquisa.
Como o agente fiscalizador utiliza a comunicação online ? A ideia de transparência pública nas redes sociais da Controladoria-Geral da União
Authors: Kniess Andressa Butture , Marques Francisco Paulo Jamil
Published: June 2021

O artigo investiga se, e de que forma, a Controladoria-Geral da União (CGU) aborda a ideia de transparência em seus perfis de redes sociais. Três questões orientam a análise: Como o tema da transparência pública é mobilizado pela CGU no Facebook e no Twitter? Uma vez que Facebook e Twitter dispõem de estruturas e usuários distintos, que estratégias de comunicação são privilegiadas em cada rede? Em que medida as rotinas de comunicação digital da CGU foram transformadas na transição entre os governos Rousseff e Temer? A análise de conteúdo de 4.212 publicações no Facebook e no Twitter em 2015 e 2016 revelou que a instituição privilegia dois temas: transparência e corrupção. Ademais, autoridades públicas são pouco mencionadas, afastando-se uma perspectiva personalista de instrumentalização da comunicação. Descobriu-se, ainda, que a transição governamental efetivamente interferiu nas rotinas de publicação da entidade.

Resumen En este artículo reflexionamos en torno a los cuerpos que se encuentran en protesta: creemos que en ese momento de alianza hay una potencia para pensar la eroticidad y sus circulaciones posibles. Para ello, recuperamos intuiciones butlerianas tales como la de la condición extática de todo cuerpo y las posibilidades de acción que ello habilita, en tensión con una reflexión acerca de mecanismos jurídicos que regulan el espacio público. Analizamos así no sólo la eroticidad en el espacio de aparición, sino también el espacio de aparición como consecuencia de lazos eróticos, de ese “entre” cuerpos sexuados en alianza
Gênero, feminismo e geração: uma análise dos perfis e opiniões das mulheres manifestantes no Rio de Janeiro

Published: June 2021

Resumo O artigo aborda perfis e opiniões de mulheres presentes na manifestação do 8 de Março de 2017 no Rio de Janeiro, sondados através de uma pesquisa de survey. A análise dos dados revelou que as variáveis cor, renda, escolaridade e orientação sexual não afetaram significativamente a opinião das entrevistadas. O que se mostrou relevante foram as diferenças por idade. Os dados apontaram também transformações na composição racial, etária e socioeconômica das feministas. A partir desses achados, investigamos a relação entre gênero, feminismo e geração no que toca estratégias e repertórios de mobilização, identidade, gênero, corpo, subjetividade, sexualidade, cultura e política.
Afetividades (co)extensíveis em “periferias” urbanas: (homo)sexualidades, amizades e pertencimentos
Authors: Reis Ramon
Published: June 2021

Resumo O artigo analisa a constituição de sentidos “familiares” e da ideia de “comunidade”, entre homossexuais, em dois bares localizados em regiões “periféricas” das cidades de São Paulo e Belém. Resultado de uma pesquisa de doutorado em antropologia sobre disputas socioespaciais, mobilidades e sociabilidades, trata-se de um esforço em: I - interpelar situações que estimulam exercícios de pertencimento e reciprocidade entre proprietárias/os e clientes, com vistas a materializar a produção de repertórios afetivos; II - perscrutar a ideia de “comunidade” acionada através de economias “informais” e de um vislumbramento protetivo (sensação de acolhimento e segurança). Notei, portanto, que a mobilização de repertórios afetivos nos bares é um modo de operar relações socioespaciais balizadas pela pessoalidade, sobretudo porque tais espaços não funcionam meramente como vetores de consumo e diversão, além de serem percebidos, dependendo do grau de proximidade, como espaços (co)extensivos não circunscritos a limites físicos.

Drag, glamour, filth: gênero e monstruosidade em Rupaul’s Drag Race e Dragula
Authors: Gadelha Dilermando , Maia Yasmim , Lima Regina Lucia Alves de
Published: June 2021

Resumo A partir de Foucault, o artigo pergunta: “Quem são os monstros de hoje?” e qual o potencial político dessas monstruosidades, principalmente nas suas relações com o gênero e a sexualidade? Parte-se do princípio de que a construção da monstruosidade contemporânea é um “nó em uma rede” (Foucault, 2013a) que compreende regularidades e dispersões com relação aos discursos anteriores sobre a monstruosidade, o gênero e o sexo. Tomamos dois realities shows americanos: RuPaul's Drag Race e Dragula e, a partir de alguns enunciados, propomos uma análise discursiva da forma como as dragqueens tensionam as noções de gênero e de monstruosidade por meio de suas próprias vidas e da construção de suas aparências.

Results for the older adults, care was linked to three main dimensions: technical care related to the institution, family care, and self-care. The meaning of care from the perspective of family members was related to the moment experienced with the institutionalization of the aged family member, mainly characterized by the dimensions of affective care, when providing comfort and technical care. For the professionals, technical care was related to the affective character. Conclusion care could be understood in different ways, from different perspectives, but it also made it possible to identify points of synchrony among the participants.

RESUMO À luz do aporte teórico da Linguística Sistêmico-Funcional (LSF), esta investigação visa, tomando como corpus de análise notícias de jornais e revistas digitais brasileiros publicados entre 2016 e 2018, refletir acerca do processo de formação de construções neológicas contemporâneas a partir do acréscimo do sufixo -aço a bases nominais, de origem portuguesa ou não. Tendo em vista esse propósito, fazemos primeiramente uma breve revisão bibliográfica com vistas a depreender o funcionamento e os valores semânticos atribuídos ao sufixo -aço em nossas gramáticas e em manuais linguísticos para, em seguida, verificar se os usos contemporâneos desse afixo são condizentes com os previstos nos compêndios especializados. A análise nos possibilitou depreender o funcionamento polissêmico desse afixo, bem como, em algumas situações, a sua metaforização decorrente da tensão estabelecida em diferentes estratos linguísticos, seja no plano da metafunção interpessoal, seja no da metafunção ideacional. Já no tocante ao plano da metafunção textual, propomos uma descrição do funcionamento na oração dos neologismos criados a partir do acréscimo de -aço a bases adjetivas e substantivas
A QUESTÃO DE ESCOLHA LINGUÍSTICA EM AMBIENTES DOMÉSTICOS NUM CONTEXTO MULTILINGUE DE MOÇAMBIQUE
Authors: LINDONDE Lourenço Mateus
Published: June 2021

RESUMO O presente estudo examinou os padrões de escolhas linguísticas em ambientes domésticos de Montepuez, Moçambique, apoiando-se em abordagens sociolinguísticas que tratam da seleção linguística em contextos multilingues, nomeadamente as noções da diglossia e domínio. Os dados foram recolhidos através de um inquérito. O estudo observou que as várias línguas são usadas em ambientes caseiros, com maior predominância o Português e o Emakhuwa, sendo nula a relação entre a formalidade e a informalidade da situação. Assim, no ambiente caseiro a tendência é o uso das línguas maternas, que incluem o Português. Do ponto de vista teórico, o estudo concluiu que nenhuma abordagem é bastante e suficientemente forte para explicar o fenómeno da escolha linguística na totalidade, apelando para uma abordagem mais integrada, De facto, observou-se que o contexto real de comunicação é construído à medida que se faz a interação, pois se considera um processo negocial, que ocorre durante e não antes ou depois do ato comunicativo. Propõe-se estudos sobre escolhas linguísticas em outros espaços territoriais da província de Cabo Delgado, incluindo estudos subordinados a atitudes linguísticas com vista ao alargamento da informação relativa aos fatores que influenciam os usos linguísticos tanto em Montepuez quanto em outras regiões da província.
The importance of Dentistry in COVID-19 pandemic and the role of saliva as a diagnostic tool
Authors: MOURA Nathalya Maria Vilela , GONZALEZ Amanda Ferreira , TABA JUNIOR Mario
Published: June 2021

ABSTRACT News of the symptoms caused by a coronavirus in humans began to be documented in December 2019, when several cases of pneumonia caused by the virus occurred in China. Studies are showing the increasing role of saliva and oral cavity in the transmission of the virus, because the receptors of epithelial cells in this region play a critical role by allowing the virus to enter those cells. The standard method to diagnose the coronavirus is based on the collection of samples in the nasopharynx and oropharynx to detect viral RNA. However, this method results in the interaction between health care professionals and patients, which increases risk of transmission; moreover, this collection can be painful for the patient and cause bleeding. As an alternative, diagnosis can be made using saliva, which only requires patients to deposit the saliva sample in a sterile container. Thus, the objective of this literature review is to present the main forms of contagion and to describe the diagnosis tools, emphasizing the risk that dental professionals are exposed to and, therefore, the growing need for better and faster diagnostic methods for coronavirus, especially using saliva. Medline, PubMed, SciELO, and Bireme databases were used for the literature search with the descriptors: Salivary diagnosis, COVID-19, and Contagion. The review explored the scientific race to develop more effective forms of diagnosis, including saliva tests, and prevention methods taking into account time, accessibility, and cost-benefit and, as a consequence, the role of dentistry has been continuously increasing.
MUCH BEYOND THE MINIMUM why do brazilian municipalities overallocate their own revenues to healthcare?
Authors: Machado José Angelo , Quaresma Guilherme , Araújo Carmem E. Leitão
Published: June 2021

Abstract This article identifies reasons for Brazilian municipalities overallocating their own revenues to healthcare which, since the promulgation of Constitutional Amendment 29/2000, have progressively expanded them until they far exceed the constitutional minimum. Linear regression models with mixed panel effects were used for the period of 2008-2017. The tested hypotheses are related to the effects of the population scale of the municipalities; the level of economic and social development of the region in which they operate; the degree of incorporation of technological resources of medium and high complexity; the effort spent on basic care; political guidance from municipal governments; and, finally, to allocation to other budgetary functions and sub-functions of interest to healthcare. The results point to two factors which better explain the dependent variable: the population scale in inverse relation, and the concentration of greater technologically complex services in a direct relation.
A Agenda de Segurança Internacional no BRICS (2009-2019)
Authors: Ramos Leonardo , Rocha Pedro D. , Zahreddine Danny
Published: June 2021

RESUMO Desde sua criação, predominaram no BRICS discussões relativas à economia política internacional, especialmente as ligadas ao desenvolvimento internacional. Entretanto, a partir das cúpulas de Sanya (2011) e Delhi (2012), questões de segurança internacional passaram a paulatinamente ocupar maior espaço dentro do grupo. Tais cúpulas são aqui entendidas como marco desse processo, e particularmente a temática da segunda, BRICS Partnership for Global Stability, Security and Prosperity, como essencial para o argumento proposto. O objetivo geral do artigo é analisar as discussões sobre segurança internacional dentro das cúpulas dos BRICS de 2009 a 2019. De modo a cumpri-lo, discute a aproximação do grupo ao nexo desenvolvimento-segurança, bem como os limites desta aproximação, e realiza uma análise de conteúdo das declarações de cúpula dos BRICS. Destacam-se na análise seis unidades temáticas e dentro de cada uma delas se sublinha a evolução das discussões e a abordagem do grupo às problemáticas.

Abstract Bourdieu and Passeron defended the thesis that the school was the main locus to legitimate and perpetuate class differences. This is reinforced by the multiple proficiency tests used to monitor public policies, which privilege the use of the formal language as part of the instruments and, therefore, penalizes participants with less mastery of the language. We adjusted two hierarchical models with Enade’s results on standard Portuguese grades, using as covariates, indicators of students’ socioeconomic status and economic independence and average values for these variables for the knowledge areas. The linguistic performance is disaggregated into three aspects: textual, orthographic and vocabulary/morphosyntactic. More affluent socioeconomic groups have greater proficiency in the Enade Portuguese Language component, even when controlling for the knowledge area average socio-economic level and financial autonomy of the students. The socioeconomic effect is not as strong as on lower educational level: university students constitute a rather homogeneous group. This reinforces Bourdieu’s thesis that through the social, cultural and economic capital still prevails the domination of wealthier classes over more popular classes, reinforcing the inequality.
Alumnado (a)normal y marginalidad en la enseñanza media chilena: qué dice el profesorado1
Authors: Doña Alberto Moreno , García Enrique Rivera , Arévalo Sergio Toro
Published: June 2021

Resumen El artículo que a continuación se presenta es el resultado de una investigación centrada y focalizada en comprender e interpretar las percepciones que los profesores(as) jefes de cuarto medio han construido con relación a los estudiantes situados en las zonas del no ser de las instituciones educativas formales. Entendemos como jóvenes situados en la zona del no ser a aquellos estudiantes que no son considerados dentro de ese concepto de normalidad por el que suele regirse la institución educativa. Bajo un enfoque paradigmático interpretativo y una metodología cualitativa, se han entrevistado a treinta docentes, todos ellos profesores jefes del curso de 4° de enseñanza media chilena y que presentan características diversas en función de variados criterios profesionales y personales. Con la ayuda del software NVivo 11.0 se realizó análisis de contenido de carácter, preponderantemente, inductivo. Se concluye que los docentes no sólo no cuestionan la conceptualización normalidad y anormalidad desde la que opera el sistema escolar, sino que la usan de manera acrítica para clasificar al alumnado. Son los resultados académicos obtenidos por los jóvenes el factor principal a partir del cual se caracteriza a los estudiantes como próximo o alejados de lo que los docentes consideran como normal. Lo humano se cosifica, se instrumentaliza y se aborda como un deber ser que debiera dirigir, según el profesorado, el quehacer de los y las estudiantes. El profesorado encuentra en la familia la principal causa en la comprensión de los motivos por los que esos jóvenes son menos normales.
The Internal Capital Markets of Global Dealer Banks
Authors: Gupta Arun
Published: June 2021

This study uncovers the existence of a trillion-dollar internal capital market that played a central role in the financing of dealer banks during the 2008 Global Financial Crisis. Hand-collecting a novel set of dealer microdata at the subsidiary level, I present the first set of facts on the evolution of interaffiliate loans between U.S. primary dealers and their (primarily foreign) siblings. First, the aggregate size of these dealer internal capital markets quadrupled from $335 billion in 2001 to $1.2 trillion by 2007. Second, 25 percent of total repurchase agreements and 61 percent of total securities lending reported on U.S. primary dealer balance sheets were sourced internally from sibling dealers by year-end 2007. Third, internal securities lending collapsed by 55 percent during the 2008 crisis. These facts suggest that incorporating internal capital market dynamics may be fruitful for future research on dealer behavior and market liquidity.

Authors:   Perm State University, Kovrizhnykh S. B. , Naumova O. B. ,   Perm State University
Published: June 2021

The features of the geomorphological structure of the Koyva River valley in the Gornozavodskiy district of Perm Krai are considered. The leading role of tectonics in formation of terraces and development of the valley of the longitudinal (relative to the folded structures of the Urals) area of the upper and middle courses is shown. The development of regional faults and thrusts at the base of the valley is associated with the formation of the Vishersko-Visimskaya depression. The formation of gold - and platinum-bearing placers is associated with the terraces location and the orientation of the Koyva River Valley.

The results of studying the structure of the Taoudeni sedimentary basin, the largest basin in north-west Africa, are presented. The characteristic features of the basin associated with the development of the West African craton, and manifestation of the Hercynian and Alpine tectonogenesis are revealed. Based on modeling data, the low rates of sedimentation of Proterozoic and Silurian-Carboniferous sediments were established that contributed to the formation of oil-and-gas source rocks. It is concluded that it is necessary to continue exploration in the basin in connection with the high prospects of oil-and-gas potential.
Statistical modeling of temperature operating modes of heating furnaces for hot strip mills
Authors: Bogatova M. Zh. , Chibizova S. I.
Published: June 2021

The article provides a method of mathematical modeling to improve temperature operating modes of heating furnaces for hot strip mills. The object of the research is the thermal operation of a continuous walking beam furnace for heating slabs before rolling. The subject of the research is statistical modeling of metal heating in furnaces of this type. The creation of a statistical model consists of factors selection, construction of regression model, correlation analysis and assessment of the variables signiﬁcance, adjustment of factors and obtaining regression equations. The main part of the research refers to a statistical model based on a comprehensive analysis. This model is based on the results of 15 automated industrial experiments on Russian heating furnaces of hot strip mills and describes the heating process in walking-beam furnace with acceptable accuracy. The adaptation of the statistical model and error calculation has been carried out. The article contains graphs comparing real temperatures and temperatures calculated on the basis of mathematical and statistical models for one of the experiments. The main conclusions are formulated based on the results of the research done. For the ﬁrst time in metallurgical practice, a statistical model has been developed that describes the process of metal heating in a ﬁve-zone continuous furnace with eight heating subzones. Since the regression function is deﬁned, interpreted and justiﬁed, and the assessment of the accuracy of the regression analysis meets the requirements, it can be assumed that the model and predicted values have suﬃcient reliability.
Newspaper reading habits of Hungarians in Transylvania.
Authors: Magyari Tivadar
Published: June 2021

The approximately one million and a half Hungarians in Romania use primarily the mass media accessible in their mother tongue. In his present study, Magyari Tivadar investigates on the basis of empirical data how Hungarians from Transylvania relate to the written press. The analysis reveals the details of the typical lecture act: reading the local newspaper. This constitutes one of the most widespread habitual acts of the Hungarian community from Transylvania, the basic form of media-consumption. It is a tradition for decades, a part of the everyday life. The author constructs a typology of readers, presenting the current situation of the publications and their perspectives for the future

Changes in the ethnic map of Kolozs and Bihar counties in the period between 1966–2002
Authors: Benedek József , Nagy Egon
Published: June 2021

The authors, József Benedek and Egon Nagy, university teachers of Social Geography at the University of Kolozsvár, conclude their analysis with the warning that the subject of the rates and number of Hungarians and half-Hungarians in Transylvania should be treated more delicately. It is certain that the ethnical losers of the socialist industrialization and village-to-town migration were the Transylvanian cities where, before the First World War, the Hungarian inhabitants formed a majority - in 1956 Kolozsvár, Hunyad, Nagyvárad etc. were mostly hungarian cities. In 2002, only Szalonta and Érmihályfalva could be counted as such. Previous researches failed to notice a group of communities where changes seemed to favor the numbers of the Hungarian population. Future strategies have to build upon this fact.
The ethnic homogenization of the villages was a success especially in villages lying close to the cities, and in strongly industrialized communities. But in the traditional hungarian ethnic enclosures (in Kalotaszeg, Mezőség) we can distinguish a group, where the rate of hungarian inhabitants has grown
An outline of the connections among political transformation, the change of the elites and market transformation
Authors: Lengyel György
Published: June 2021

The study deals with issues related to the types of connections between institutions and elites in the context of political transformations. Its essential message is that the asynchronies produced between elite structures and institutional structures determine whether the transformation will be peaceful or violent, controlled or of a spontaneous character. Subsequently, the paper presents the dimensions of elite circulation, and it discusses the relations between the ways of elite change and institutional changes. It reviews the theories of the connections between political changes and market transformation, concluding with the statement that real political transformation can only occur if it brings along both market and political changes
