Mimicking the natural thermal environments experienced by seeds to break physiological dormancy to enhance seed testing and seedling production
Authors: Baskin Carol C. , Baskin Jerry M.
Published: April 2022

Physiological dormancy (PD) is the most common class of seed dormancy on earth. It is highly variable and is an important part of the adaptation of many species to their habitat. Often, two questions are asked about seeds that failed to germinate in a germination test: (1) are they
non-viable or dormant, and (2) if dormant do they have PD and how is it broken? We provide an overview on how to approach studies of species with PD for which few or no data are available. Information about habitat environmental conditions during the seed stage can be used to formulate hypotheses
on dormancy-breaking and germination requirements. These hypotheses can be tested by a move-along experiment. There are three levels of PD, and they are distinguished by the conditions required to break PD and promote germination. Seeds with non-deep PD (the most common level of PD) require
different conditions for dormancy-break and germination, i.e.a change in the season, while those with intermediate and deep PD germinate at the dormancy-breaking conditions, e.g.during a long period of cold stratification. Knowing how to break PD enhances testing for seed viability and helps
ensure high germination percentages of viable seeds.

Published: April 2022

Genetic testing is becoming increasingly required at almost every stage of failed female reproduction/infertility. Nonetheless, clinical evidence for the majority of identified gene–disease relationships is ill-defined, thus leading to difficult gene variant interpretation and poor translation of existing knowledge into clinics. We aimed to identify the genes that have ever been implicated in monogenic female reproductive failure in humans and to classify the identified gene–disease relationship pairs using a standardized clinical validity assessment. A PubMed search following PRISMA guidelines was conducted on 20 September 2021 aiming to identify studies pertaining to genetic causes of phenotypes of female reproductive failure. The clinical validity of identified gene–disease pairs was assessed using standardized criteria, counting whether sufficient genetic and experimental evidence has been accumulated to consider a single gene ‘characterized’ for a single Mendelian disease. In total, 1256 articles were selected for the data extraction; 183 unique gene–disease pairs were classified spanning the following phenotypes: hypogonadotropic hypogonadism, ovarian dysgenesis, premature ovarian failure/insufficiency, ovarian hyperstimulation syndrome, empty follicle syndrome, oocyte maturation defect, fertilization failure, early embryonic arrest, recurrent hydatidiform mole, adrenal disfunction and Mullerian aplasia. Twenty-four gene–disease pairs showed definitive evidence, 36 – strong, 19 – moderate, 81 – limited and 23 – showed no evidence. Here, we provide comprehensive, systematic and timely information on the genetic causes of female infertility. Our classification of genetic causes of female reproductive failure will facilitate the composition of up-to-date guidelines on genetic testing in female reproduction, the development of diagnostic gene panels and the advancement of reproductive decision-making.
Perioperative Use of Pituitrin after Cardiac Defect Repair in Adult Patients with Severe Pulmonary Hypertension
Authors: Li YunTao , Tung Mingwui , Xu Jianping , Pan Guangyu , Jiang Rui
Published: April 2022

Background: Vasopressin can constrict peripheral arteries without constricting the pulmonary artery. Theoretically, vasopressin is suitable for the perioperative treatment of pulmonary hypertension. Few studies have investigated the use of pituitrin (a substitute for vasopressin) after cardiac defect repair surgery. This study aimed to analyze the effect of pituitrin on hemodynamics and to determine whether pituitrin can be used after surgical repair in adult patients with pulmonary arterial hypertension-congenital heart disease (PAH-CHD).
Methods: A pulmonary artery catheter was used in all the patients for hemodynamic monitoring. Hemodynamic parameters were recorded before and at 0.5 h, 1 h, 6 h, 12 h and 24 h after pituitrin administration. The changes in the hemodynamic parameters before and after pituitrin use were analyzed through repeated measures analysis of variance.
Results: A total of 110 patients with PAH-CHD underwent repair surgery; 23 patients were included in further analysis, including 11 with atrial septal defect, 9 with ventricular septal defect, and 3 with patent ductus arteriosus. Ten (43.5%) were men, with a mean age of 29.4 ± 6.8 years. Hemodynamic parameters before and after the oxygen test were as follows: radial artery oxygen saturation, 91.5% ± 4.4 vs. 97.9 ± 2.4%; pulmonary vascular resistance, 10.5 ± 1.8 Wood units (wu) vs. 5 ± 1.2 wu; systemic-pulmonary blood flow ratio (QP/QS), 1.1 ± 0.2 vs. 2.1 ± 0.9. With prolonged use, the systolic blood pressure of the radial artery increased significantly (P = 0.001), that of the pulmonary artery decreased significantly (P = 0.009), and RP/s decreased significantly (P < 0.001).
Conclusion: Pituitrin as an alternative to vasopressin can increase arterial pressure, decrease pulmonary artery pressure, and reduce the pulmonary artery pressure/arterial pressure ratio after repair surgery in adult patients with PAH-CHD.
THE "STOYANIE NA KOSTYAKH" TOPOS IN ANCIENT RUSSIAN BATTLE NARRATIVES
Authors: Sokolova Lidia
Published: April 2022

The article presents the analysis of the stoyanie na kostyakh (standing on bones) topos, which is present in battle narratives of the 13th—17th centuries. In battle chronicles this topos is most often expressed by the verbal formula stal na kostyakh (meaning “he has won”), referring either to a prince or to soldiers in general. Instead of the formula stali na kostyakh (they have won), it is sometimes reported how many days the victorious soldiers stoyali na kostyakh, that is, how many days they stayed at the site after the battle. The most interesting use of the topos is revealed in the The Tale of the Battle with Mamai. In this text the fixed expression stal na kostyakh refers to Prince Vladimir Andreevich, whom the author depicts as the main hero of the battle, despite tradition. At the same time, the author provides a detailed account of the stoyanie na kostyakh ritual performed by the victorious soldiers led by Dmitry Ivanovich and reports that “the great prince has been standing on the bones for eight days behind the Don.” Both ancient Russian authors and modern researchers understand the meaning of this ritual reflected in the works of poets and artists in different ways.
OBTAINING OF PLANT TISSUE CULTURE Scutellaria baicalensis GEORGI. AND ITS BIOCHEMICAL ANALYSIS
Authors:   Institute of Molecular Biology and Genetics of the National Academy of Sciences of Ukraine, Kyiv, Poronnik О. О.
Published: April 2022

Aim. To obtain a plant tissue culture of S. baicalensis as a possible source of biologically active compounds (BAC) with a wide range of pharmacological action. Methods. Plant tissue culture, photocolorimetric method, reversed-phase high performance liquid chromatography (HPLC) method. Results. Two stably productive plant tissue culture strains (16SB3 and 20SB4) of S. baicalensis were obtained from fragments of roots seedling on a specially developed agar nutrient medium 5С01. The yield of dry biomass from 1 liter of this medium per passage (21st day of growth) for strain 16SB3 is 25–30 g, for strain 20SB4 – 30–40 g. The total content of flavonoids in dry biomass was in terms of routine for strains 16SB3 and 20SB4 – 0.6–0.9 and 0.7–0.9 mg/g, respectively, and the yield of flavonoids – 18–27 and 21–36 mg/l of nutrient medium, respectively. BAC typical for plants in nature, in particular, flavonoids vogonin, baikalein, neobaikalein, skulkapfavon and their derivatives, were found in the studied biomass of both strains. Conclusions. It was found that the biomass of the two strains of S. baicalensis plant tissue culture accumulated the same BAC, in particular, flavonoids, as do plants in natural conditions. The resulting plant tissue culture is promising as a possible source of Baikal skullcap BAC.
SIMULTANEOUS IDENTIFICATION, QUANTIFICATION, AND ANALYSIS OF MAIN COMPONENTS OF “HAIRY” ROOT EXTRACTS OF Artemisia annua AND Artemisia tilesii PLANTS
Authors:   Dumansky Institute of Colloid and Water Chemistry of of the National Academy of Sciences of Ukraine, Kyiv, Kobylinska N.
Published: April 2022

Aim. The profiles of polyphenolic phytochemicals in extracts of “hairy” roots of Artemisia tilesii Ledeb. and Artemisia annua L. were studied. Analytical separation and quantification of main components in extracts were evaluated. Methods. “hairy” roots were grown in vitro on Murashige and Skoog medium. High-performance chromatography coupled with different types of detection (photo diode array detection (DAD) and electrospray ionization with ultra-high resolution Qq-Time-of-Flight mass spectrometry) was used to identify and quantify the main biologically active components in ethanol extracts of “hairy” roots. Results. The amount of flavonoids was 94.71–144.33 mg RE/g DW and 33.52–78.00 mg RE/g DW in “hairy” roots of A. annua and A. tilesii, respectively. In most samples of “hairy” roots, the amount of flavonoids was higher than the content in the control plant roots. The presence of Apigenin (0.168 ± 0.003 mg/L and 0.178 ± 0.006 mg/L), Quercetin (0.282 ± 0.005 mg/L and 0.174 ± 0.005 mg/L) in the extracts of A. annua and A. tilesii was shown by reverse-phase HPLC-DAD method. Chlorogenic acid, Kaempferol, and other flavonoids were detected. Conclusions. The developed HPLC-DAD method demonstrated the high percentage of recovery, low limit of detection and quantification (9,11 ng/ml ≤ LOQ ≤16,51 ng/ml), accuracy and correctness. Thus, the method is suitable for the simultaneous quantification of phenolic acids and flavonoids in various plant extracts with short time and high efficiency.
25% Dextrose Versus 24% Sucrose for Heel Lancing in Preterm Infants: A Noninferiority RCT
Authors: Sasidharan Rohit , Gupta Neeraj , Yadav Bharti , Chawla Deepak , Singh Kuldeep , Kumarendu Singh Arun
Published: April 2022

OBJECTIVES

To compare the efficacy of 25% dextrose with 24% sucrose for heel-lance analgesia in preterm infants admitted to the NICU.

METHODS

In this noninferiority, double-blind, randomized controlled trial, preterm infants born at 28 weeks and 0 days to 35 weeks and 6 days of gestation who were due for a scheduled heel-lance procedure were enrolled. Infants randomly assigned to the intervention arm received 0.5 mL 25% dextrose, whereas infants in the active control group received 0.5 mL 24% sucrose orally just 2 minutes before the heel-lance procedure. The primary outcome was Premature Infant Pain Profile (PIPP) score 30 seconds after the procedure. Secondary outcomes included PIPP scores at 60 and 120 seconds, PIPP-Revised scores at 30, 60, and 120 seconds, and any adverse events.

RESULTS

Sixty-four infants were enrolled (32 in each group). The mean (SD) PIPP score at 30 seconds was 6.41 (2.56) in the dextrose group and 7.03 (2.23) in the sucrose group (mean difference, −0.63 (95% confidence interval, −1.85 to 0.60; P = .31). The upper margin of the confidence interval did not cross the predefined noninferiority margin of 2. The mean PIPP scores at 60 (5.03 [2.18] vs 5.39 [1.48]) and 120 (4.75 [1.97] vs 4.94 [1.46]) seconds were also similar. The PIPP-Revised scores between the 2 groups at all time intervals were comparable. One infant in the intervention group had a transient coughing episode.

CONCLUSIONS

In preterm infants under intensive care, 25% dextrose is noninferior to 24% sucrose for heel-lance analgesia as assessed by PIPP score.

Telemonitoring through multiple variables measured on cardiac devices has the potential to improve the follow-up of patients with heart failure. The HeartLogic algorithm (Boston Scientific), implemented in some implantable cardiac defibrillators and cardiac resynchronisation therapy, allows monitoring of the nocturnal heart rate, respiratory movements, thoracic impedance, physical activity and the intensity of heart tones, with the aim of predicting major clinical events. Although HeartLogic has demonstrated high sensitivity for the detection of heart failure decompensations, its effects on hospitalisation and mortality in randomised clinical trials has not yet been corroborated. This review details how the HeartLogic algorithm works, compiles available evidence from clinical studies, and discusses its application in daily clinical practice.

Published: April 2022

Cultured buttermilk is a dairy beverage with a high nutritive value. In the current study, functional cultured buttermilk was formulated using probiotic Lactobacillus plantarum and flaxseed fortification to improve the potential health benefits. The cultured buttermilk samples were analysed for pH, lactic acidity, colour, phase separation, viscosity, microbiology and sensory properties. The results showed non-significant changes in acidity and pH. However, flaxseed fortification decreased phase separation and increased viscosity of buttermilks. In addition, a significant difference in colour attributes was revealed between samples. Sensory characteristics of cultured buttermilks were acceptable to produce a functional food.
Theology Giving Back
Authors: Fortin Jean-Pierre
Published: April 2022

This essay lays foundations for a postmodern theology of donation by supplementing Jacques Derrida’s philosophy of the gift with Marcel Hénaff’s analysis of ceremonial gift exchange, John Milbank’s theology of reciprocal exchange and Hans Urs von Balthasar’s Trinitarian kenotic theology. Derrida’s philosophy of the gift provides normative criteria for the experience of transcendence within human conscious awareness. Hénaff and Milbank nuance and expand Derrida’s theory of the gift by demonstrating the asymmetrical and open-ended character of human interactions. Balthasar’s kenotic theology fleshes out Milbank’s communal understanding of donation. Jesus Christ embodies the gift, empowering human beings to bear witness before God and one another as a community able to give and receive unconditional love.
Making microteaching matter
Authors: Rieker Jacob
Published: April 2022

Microteaching is a core second language teacher education practice. Yet, there is a lack of consensus surrounding what exactly it means to engage in microteaching and how teacher educators can intentionally make this practice relevant for teacher development. Addressing these issues, the present study utilizes Vygotskian sociocultural theory (Vygotsky, 1978, 1986, 1987) to reconceptualize the microteaching simulation as play activity. Contrary to the colloquial understanding of play, a Vygotskian perspective frames play as a serious activity with developmental consequences. Using a novel conceptualization of play as (1) artificial, (2) futureoriented, and (3) mediational, I analyze dialogic episodes from the practice teach, a Vygotskian inspired microteaching simulation embedded within an MA TESL course. I demonstrate how play was co-constructed by the teacher educator, teachers enacting microteaching lessons, and teacher peers, and show how this play led the teachers to become aware of the reasoning behind their pedagogical activities. These episodes illustrate how engagement in the practice teach opened up possibilities for the teachers to function ahead of their current developmental levels through play. Ultimately, a Vygotskian perspective grounded in the value of play offers the potential to reclaim the relevance of microteaching as a meaningful second language teacher education practice.
Operationalizing reflective practice in second language teacher education (SLTE)
Authors: Farrell Thomas S C
Published: April 2022

Reflective practice in the field of TESOL has been warmly embraced in many teacher education and development programs worldwide. However, one of the important issues that is still not clear to many educators is how reflection should be implemented. In this article, I argue that one of the reasons for the confusion about operationalizing reflective practice is that most of the existing approaches that have blossomed since the 1990s are restrictive. Thus, a more holistic approach to reflection should be adopted through the framework for reflecting on practice in SLTE.

Study of aerodynamic characteristics of an aircraft during approach to landing in a disturbed atmosphere
Authors: Vyshinsky Victor V. , Chinh Doan Cong
Published: April 2022

An approximate method is proposed for determining the aerodynamic effect of coherent vortex structures (CVS) of atmospheric turbulence on an aircraft. As a source of the CVS the vortex wind wakes arising when the atmospheric wind flows around the mountain massif of the Son Tra peninsula, located near the Da Nang airport, and the vortex wake behind the Su-27 type aircraft in the landing configuration are considered. Modeling the formation of a vortex structure is carried out by the grid method within the framework of the boundary value problem for the Reynolds-averaged Navier—Stokes equations. The evolution and stochastics of the far wake are modeled in a two-dimensional approximation by discrete Rankine vortices. The assessment of the increment of forces and moments from the effect of the vortex system on the aircraft was carried out within the framework of the panel method. The situation is considered when a light transport aircraft gets into a vortex wake behind an aircraft with a swept wing and a passenger aircraft of the MS-21 type, approaching for landing at the CVS from a mountainous terrain.
Taxation-Based Indicators as a Measure of Income Inequality in Russian Regions
Authors:   P.G. Demidov Yаroslavl State University, Yаroslavl, Russian Federation, Pugachev A. A.
Published: April 2022

Russia is one of the most unequal of the world’s major economies, with its wealth and income inequalities having drastically increased in recent years. This study aims to describe the influence of the flat personal income tax on income inequality in Russia and its regional characteristics by analyzing per capita tax revenues. The hypothesis is that the system of income taxation that existed in Russia until 2021 did not help reduce income inequality but on the contrary, exacerbated it, which is particularly evident on the regional level. Methodologically, the article relies on statistical analysis of concentration indices, time series analysis, index method, and comparative analysis. The calculations were made with the help of the Analysis ToolPack in MS Excel by using the data on 85 Russian regions. To test the hypothesis, 7 indicators were calculated: the range of variation, standard deviation, coefficient of variation, decile ratio of funds, decile ratio of differentiation, quintile ratio of funds, and the Gini index for 85 Russian regions for the period from 2006 to 2020. In the given period, these indicators remained steadily at a high level with a slight decrease in 2008–2010. Judging by the dynamics of the Gini index calculated by Rosstat, income inequality tended to decline although there were no significant changes in the regional differences in income while regional inequality also remained high. Monetary income and gross regional product are distributed more evenly across Russian regions in comparison with the personal income tax revenues and tax revenues in general of the regional governments’ consolidated budgets. The findings confirm the hypothesis and show that the personal income tax, which is an essential element of the tax system, exacerbated the situation of inequality in Russian regions. These findings can be of use to policy-makers and contribute to further research on taxation instruments and their potential to reduce or mitigate inequality.
Determinants of the Proportional Income Tax Revenue: A Comparative Assessment of Russia and Bulgaria
Authors:   Southwest University “Neofit Rilski”, Blagoevgrad, Bulgaria, Tanchev S.
Published: April 2022

Initially flat-rate income taxes only existed in tax havens, but presently, 26 countries have adopted the proportional tax as a fiscal instrument to increase budget revenues and accelerate economic growth. This article empirically examines the determinants affecting the revenues from a proportional income tax with non-taxable minimum (negative flat tax) used in Russia and a proportional income tax without non-taxable minimum (pure flat tax) used in Bulgaria. The research objective is to estimate the impact of the macroeconomic variables such as gross disposable income, employment, gross capital formation and government expenditures on the revenue from the proportional income tax in Russia and Bulgaria. The study employs an ordinary least square (OLS) method and quarterly seasonally adjusted data for the period 2008–2020. For Russia, quarterly seasonally adjusted data for the period from March 2008 till December 2020 were used, including 52 observations. For Bulgaria, quarterly seasonally adjusted data for the period from March 2008 till March 2020 were used, including 49 observations. Basing on the results, it may be inferred that the increase of the gross disposable income and higher marginal tax rate of the proportional tax with a non-taxable minimum collect more nominal revenue in the budget, as Russia’s example showed. The increase of the employment related with a lower marginal tax rate of the proportional income tax without a non-taxable minimum collect less nominal revenue as Bulgaria’s example shows. A standpoint of the revenue in the budget the proportional income tax with non-taxable minimum is more effective than proportional income tax without non-taxable minimum.
Aspectos institucionais da performance fiscal de estados e municípios
Authors: MENDES MARCOS
Published: April 2022

RESUMO Este artigo mostra que as regras estabelecidas para controlar a dívida estadual e municipal no Brasil são ineficientes. Eles não podem impedir o crescimento excessivo da dívida nem evitar a aprovação de empréstimos que tenham uma relação benefício-custo negativa. O artigo utiliza modelos teóricos propostos por Shepsle e Weingast (1981) e Niou e Ordershook (1985), relacionados a projetos de barril de porco, para mostrar que o Senado Federal, responsável pelo controle da dívida, não possui incentivos suficientes para restringir a dívida. A estratégia escolhida pela maioria dos senadores, tentando maximizar a probabilidade de ser reeleito, resulta na aprovação de todos os pedidos feitos pelos estados e municípios que desejam obter empréstimos. O artigo propõe mudanças nas regras de controle, para torná-las eficientes.

RESUMO É apresentada uma descrição de um programa de pesquisa sobre a natureza incompleta do conhecimento científico e ampliado para analisar o currículo mínimo de economia no Brasil e a consequente mutação de propostas de mudança. Considerando os diferentes níveis de abstração na ciência pura, na ciência aplicada e na arte da tricotomia científica, observa-se que o currículo mínimo prescreve treinamento adequado para a economia social ou aplicada. Conclui-se que um período adicional de dois anos é recomendado, um para fortalecer a economia pura no ciclo básico e outro para a arte da economia na fase destinada ao treinamento profissionalizado. Consideração também é dada à especialização em economia pura voltada exclusivamente para o ensino e pesquisa

Authors: Cunha Neide de Brito , Ferraz Adriana Satico , Santos Acácia Aparecida Angeli dos
Published: April 2022

Abstract This study aimed to investigate the association between intrinsic and extrinsic motivation for the use of cognitive and metacognitive learning strategies in technologists. Possible differences in both constructs in terms of sex and course were also analyzed. Participants were 96 students from two technological courses at a public education institution in the state of São Paulo. The Motivation to Learn Scale for University Students and the Scale for Learning Strategies for University Students were used. The results showed the prevalence of intrinsic motivation and metacognitive strategies. The motivational orientations were positively related to cognitive and metacognitive strategies. There were no differences regarding gender, or the course attended. New studies should broaden the knowledge about the characteristics of this public, whose course curricula are directed toward inclusion in the labor market and include practical activities as a reality.

Published: April 2022

Abstract Social isolation due to the global pandemic influenced not only the way how people interact, but it also brought a huge impact on the population’s mental health, regardless of their age. This study aimed to evaluate the intensity of symptoms of depression and anxiety, perceived stress, levels of loneliness, and psychological well-being in the elderly during social distancing due to the COVID-19 pandemic. The study included 86 elderlies, aged 60 to 90 years old (M=70.95; SD=7.08), living in the southern region of the country. They were interviewed by a WhatsApp video call and responded about symptoms of stress, anxiety, loneliness, depression, and positive mental health. The results showed that 55.8% had high stress symptoms, 18.6% anxiety symptoms, 16.3% depression symptoms, and 5.82% moderate to severe loneliness. It was found that participants who felt more alone had lower well-being scores.

Published: April 2022

Abstract Purpose: To analyze how the Covid-19 has impacted the financing, capital structure, and investment policies of Brazilian companies from a behavioral finance perspective. Originality/value: The study focused on the behavioral finance literature, Prospect Theory, Big Five Theory, and Pecking Order Theory, in order to substantiate and explain the consequences of the emotions implicit in corporate decisions and their impacts on organizations during the Covid-19 crisis. Design/methodology/approach: A questionnaire was used, containing 26 questions spread over three sections: 1. investment, financing, and capital structure decisions made in the first half of 2020; 2. personality dimensions of the respondents; and 3. sociodemographic profiles of the respondents. A total of 120 responses was obtained and the ordinary least squares econometric model was applied to identify the influence of biases on corporate decisions. Findings: The results found showed that managers’ decisions have been influenced by heuristics and biases, especially decisions on starting new projects and raising funds, as it was found that overconfidence bias has prevailed in investment and financing decisions. The study also demonstrated that the decline in sales and lost profitability of Brazilian companies due to Covid-19 have led to bold behavior by managers, as they have sought to reverse the impacts of the pandemic.

Obtiveram-se 120 respostas, e aplicou-se o modelo econométrico mínimos quadrados ordinários para identificar a influência dos vieses nas decisões corporativas. Resultados: Os resultados encontrados evidenciaram que as decisões dos administradores têm sido influenciadas pelas heurísticas e pelos vieses, principalmente nas decisões de iniciação de novos projetos e captação de financiamento, pois identificou-se que o viés do excesso de confiança tem prevalecido nas decisões de investimento e financiamento. O estudo também demonstrou que as quedas nas vendas e as perdas na lucratividade das empresas brasileiras decorrentes da Covid-19 proporcionaram um comportamento arrojado nos administradores, já que eles buscaram reverter os impactos da pandemia.
Academic women: A study on the queen bee phenomenon
Authors: Gomes Neto Manoel B. , Grangeiro Rebeca R. , Esnard Catherine
Published: April 2022

Abstract Purpose: In masculine and extremely competitive organizational contexts, women who succeed in their careers exhibit behaviors that hinder, rather than help, other women to develop professionally. This phenomenon is called queen bee. In this article, we aim to identify whether the queen bee phenomenon is present in higher education institutions (HEI) in Brazil. Originality/value: Although the queen bee phenomenon as a gender inequality metaphor is not a recent topic in scientific literature, its analysis in Brazilian HEI reveals the original character of the study. Design/methodology/approach: The quantitative study has a sample of 495 women who work in HEI. The MANOVAs test was used to verify the hypotheses. Findings: The results show that the knowledge domain impacts more on the queen bee phenomenon than the variables of the organizational context. In addition, women in leadership positions are more engaged at work, have more masculine traits, identify themselves with women at the top of the hierarchy, deny gender discrimination and tend to be more adept at meritocratic discourse than women who are not in leadership positions, confirming that women who hold leadership positions in Brazilian HEI present queen bee traits.

Com base em revisão de literatura e em entrevistas, foi elaborado um questionário composto de 40 itens, com respostas padronizadas em escala do tipo Likert, o qual continha também uma seção destinada a identificar variáveis demográficas e funcionais dos respondentes. Após validação semântica e de conteúdo, o referido questionário foi respondido por 585 gestores da organização pesquisada, que representam cerca de 10% do universo. A análise fatorial realizada revelou a existência de dois fatores: preditores de resistência e preditores de expectativas, tendo permanecido 38 dos 40 itens do questionário. As análises estatísticas mostraram também que os respondentes que estão estudando e os que ocupam o cargo de gerente de Ponto-de-Venda apresentam expectativas mais positivas a respeito da remuneração por competências. Além disso, a pesquisa gerou um instrumento que poderá ser replicado por outras organizações. Ao final são apresentadas recomendações à organização pesquisada a respeito de remuneração por competências e sugestões de novas pesquisas.

Abstract Introduction Endodontically treated teeth are usually affected by extensive structure loss requiring the use of intraradicular posts to provide retention and restoration. Objective An in vitro assessment was performed on the bonding of glass fiber posts to the root dentin. Material and method Ninety (n = 10) single bovine roots were used in a 3 x 3 x 3 factorial study with subdivided plots: post customization varying the presence and type of resin (without customization, conventional resin, and Bulk Fill resin), light-curing device (Valo, Radii-Cal, Rainbow), and root third (cervical, middle, and apical). Result For the customization factor, Tukey’s test (5%) showed the superiority of the Bulk Fill (8.16 MPa) and Z350 (7.40 MPa) groups compared to the control group (4.92 MPa), without differing from each other. All light-curing devices differed, showing the superiority of Valo (9.36 MPa), Radii (6.96 MPa) as an intermediate, and the inferiority of Rainbow (4.17 MPa). The cervical root third (7.81 MPa) was superior, the apical third was inferior (5.80 MPa), and the middle third (6.88 MPa) was an intermediate without differing from the others. Conclusion The customization of glass fiber posts increases the bond strength to the root dentin, regardless of the resin used. There was a compromise in the apical third and when using light-curing devices with lower light intensity.
COMO UM COMPASSO. O CONSELHEIRO AIRES E A FORMA LIVRO EM MACHADO DE ASSIS

Resumo Os dois últimos romances machadianos distinguem-se por terem um autor ficcional comum, o Conselheiro Aires. Obedecem, no entanto, a uma forma literária diferente: Esaú e Jacó, ao romance, sendo a narração atribuída a um narrador omnisciente, em terceira pessoa; Memorial de Aires, ao diário, narrativa em nome próprio e que se mostra em curso de escrita. Apesar da diferença de forma narrativa, é possível reconhecer-lhes características comuns. Neste texto, discutirei o modo como a forma livro é tratada nestes romances finais de Machado de Assis, defendendo, a este propósito, ser possível delimitar um projecto literário próprio do Conselheiro Aires, identificável e isolável no universo da poética machadiana.

RESUMO A evasão no Ensino Superior constitui preocupação internacional com impacto nas Instituições de Ensino Superior, em geral, e nos percursos de carreira individuais, em específico. Para prevenir esse fenômeno e apoiar tanto instituições como estudantes na sua tomada de decisão, urge identificar fatores de evasão no ensino superior. Apresenta-se revisão de artigos publicados em revistas científicas internacionais entre janeiro 2014 e dezembro 2018, com base no Modelo Longitudinal de Evasão Institucional. A pesquisa foi realizada em quatro bases de dados, com combinações das palavras-chave dropout, departure, academic adjustment, college adjustment, academic integration, social integration e higher education. Foram lidos integralmente 24 artigos que satisfaziam critérios de inclusão. Procedeu-se à descrição dos artigos e o conteúdo foi sistematizado em meta-síntese. Identificaram-se fatores relativos a atributos prévios à entrada no ensino superior; objetivos e compromissos prévios e posteriores a essa entrada; experiências institucionais; integração acadêmica e social. Identificaram-se ainda medidas de sinalização de evasão. Discutem-se implicações para a investigação, para serviços e políticas das Instituições de Ensino Superior.

RESUMO O presente estudo foi produzido para conhecer como os professores universitários vivenciaram a transição da educação superior presencial para a docência no ensino à distância, focalizando a subjetividade docente nas variações decorrentes da nova situação de trabalho. Metodologicamente trata-se de uma pesquisa qualitativa conduzida pela realização de entrevistas semiestruturadas e que adotou como estratégia o estudo de caso visando a caracterização detalhada das mudanças produzidas nos modos de trabalhar. A discussão dos resultados revelou a enorme distância existente entre o ensino presencial e a EAD (Educação à Distância) o que evidenciou a adoção de estratégias de inserção de manutenção nas novas condições laborais. Foram evidenciados os processos de subjetivação dos docentes assim como os procedimentos de controle que passam a incidir sobre o trabalho docente na nova modalidade. Como conclusão provisória destacou-se o desaparecimento da relação presencial e a precarização do trabalho docente.

Abstract: The size of soybean seeds needs further study because its relationships with physiological quality, field establishment, and yield are controversial. The aim of this study was to evaluate the effects of seed size on soybean establishment and seed physiological quality. In the field, a 2x3x3 factorial design was used, with two cultivars (M 5947 IPRO and 59HO124 IPRO), three seed sizes (5.5, 6.0, and 6.5 mm), and three sowing densities (280,000, 320,000, and 360,000 plants.ha-1). Agronomic traits and grain yield were evaluated. After harvest, only seeds from plots with a population of 320,000 plants were classified by size using circular sieves with 5.5-mm, 6.0-mm, 6.5-mm, and 7.0-mm mesh sizes. For the evaluation of physiological quality, a 2x4 factorial design was applied, with two cultivars and four seed sizes. Germination, seedling emergence, accelerated aging, seedling dry matter, and emergence speed index were evaluated. Smaller seeds gave rise to shorter plants with a lower first pod insertion height. Larger seeds had higher physiological quality. The M 5947 IPRO cultivar showed better seed performance and quality.

Abstract: Representative seed lot sampling is important in analyzing seed quality. This study aimed to determine whether sampling during processing and after packaging using samplers interferes in analyzing the physiological quality and health of soybean seed lots. The study was conducted with six and twelve soybean seed lots produced in the 2017/2018 and 2018/2019 growing seasons, respectively. Two sampling methods were used, according to the Rules for Seed Testing: a) sampling during processing; b) sampling of seed lots stored in bags using a sampler. Seed quality was assessed by germination percentage, accelerated aging, and tetrazolium tests to determine vigor, and seed health using the blotter test. Sampling during processing and after storage in bags differ in the expression of seed vigor and health. Seed lot homogeneity is essential to determine the difference between sampling methods. Sampling in the processing flow is more representative and may be indicated for the germination test.

RESUMO Objetivo caracterizar o desempenho de adolescentes em consciência fonêmica e verificar a associação entre essa habilidade e a leitura de palavras. Métodos participaram do estudo 83 adolescentes, sendo 58 do gênero feminino e 25 do gênero masculino, com idades entre 11 e 16 anos, matriculados do 6º ao 9º ano do ensino fundamental II de duas escolas públicas de Belo Horizonte. Foram aplicados testes de consciência fonêmica e a prova de leitura de palavras e pseudopalavras. Resultados os adolescentes apresentaram maior dificuldade em realizar a tarefa de segmentação fonêmica. Em contrapartida, na execução das tarefas de subtração de consoante/vogal/consoante e inversão, houve efeito teto. Observou-se correlação positiva entre as tarefas da consciência fonêmica e a leitura de palavras e pseudopalavras. Conclusão O desenvolvimento da consciência fonológica ainda é necessário na adolescência e, além disso, se pode dizer que o desenvolvimento dessa habilidade contribui de forma significativa para o bom desempenho da leitura no ensino fundamental II
