Abstract: Over the last decades, the incidence of skin cancer, melanoma and non-melanoma,has increased at a continuous rate. In particular for melanoma, the deadliest type of skin cancer, early detection is important to increase patient prognosis. Recently, deep neural networks (DNNs) have become viable to deal with skin cancer detection. In this work, we present a smartphone-based application to assist on skin cancer detection. This application is based on a Convolutional Neural Network (CNN) trained on clinical images and patients demographics, both collected from smartphones. Also, as skin cancer datasets are imbalanced, we present an approach, based on the mutation operator of Differential Evolution (DE) algorithm,to balance data. In this sense, beyond provides a flexible tool to assist doctors on skin cancer screening phase, the method obtains promising results with a balancedaccuracy of 85% and a recall of 96%.

Authors: Barannikov Mikhail V. , Polyakov Igor’ V. , Vinogradova Lyubov’ A. , Polyakov Vyacheslav S.
Published: July 2022

Introduction. Faster construction and commissioning of industrial and civil facilities is a main factor affecting their operational characteristics at the stage of construction due to high-quality multifunctional additives, having plasticizing properties, coupled with the accelerated curing of composite materials in cement binders. The article addresses a study on the influence of a new multifunctional additive on the physical and mechanical properties of heavy concretes, that determines its plasticizing properties and affects concrete strength.

Materials and methods. The study focuses on concrete B30. The Vicat apparatus was used to test the cement paste to identify its normal density and setting time according to GOST 310.3. The strength of cubic specimens was tested using hydraulic press P-120 according to GOST 1080-90.

Results. The multifunctional additive was obtained by synthesizing caprolactam mixed with polyalkylene glycol and amino alcohols. The test on the setting time of the cement paste has proven that the multifunctional additive plasticizes, if added to heavy concrete mixes. The impact of the concentration of the multifunctional additive on the setting time, compressive strength and slumping of the concrete mix has been identified. These new data were applied to find the optimal interval of concentrations of the multifunctional additive, added to the concrete mix to make densely reinforced concrete products. The optimal concentration interval is 0.2–0.3 % of the cement mass.

Conclusions. The multifunctional additive made of domestic chemical products as a result of the study, improves physical and mechanical characteristics of concrete mixes to be used in the construction of civil and industrial construction facilities.

Published: July 2022

Introduction. Trends and prospects of the application of innovations in control of the construction and special equipment in construction process are considered in the article. The relevance of this subject is explained by the general orientation of domestic economy toward the innovative development without which any further improvement of the products quality, an increase in labour productivity, cost reduction of construction production, decrease in the environmental damage, accident rate, damage to workers’ health and improvement of the conditions of their work is impossible.

Materials and methods. The system approach, methods of the structural analysis, methods of classification and groups, the comparative and statistical analysis and forecasting, methods of expert estimates were used during the research. Works, published by domestic and foreign authors, experience of construction companies, statistics of Rosstat, materials of the Agency of innovations of the city of Moscow, materials of business programmes of specialized exhibitions were used as the material for the research.

Results. The authors systematized the existing innovative technologies of control of the construction and special equipment at the construction stage. These technologies are divided into two main groups: means of telematics and means of achievement of autonomy of equipment and transport. Some advantages of the use of these technologies, as well as some possible negative consequences are identified. The system of indicators of efficiency of introduction and use of innovative technologies of control of special and construction equipment is proposed for the development of an innovations efficiency assessment technique.

Conclusions. The analysis proves the efficiency and expediency of innovative technologies in control of the equipment and transport during the construction process. Certain conditions are required for the development of this innovative area, first of all, intensive production of special devices and programmes, a decrease in their price and higher availability, legal regulation improvement, professional development of the construction companies’ staff.

A ANTINOMIA JURÍDICA REAL ENTRE O DIREITO À MATERNIDADE DIGNA NO CÁRCERE E O PRINCÍPIO DA INTRANSCENDÊNCIA DA PENA EM FACE DA SITUAÇÃO CONCRETA DO ESTABELECIMENTO PENAL IRMÃ IRMA ZORZI
Authors: Farias Filho Marcio José
Published: July 2022

O estudo do tema parte da observação do aumento da criminalidade feminina, que ocasiona o aumento do aprisionamento de mulheres e gera um maior enfoque à maternidade na prisão. O direito à maternidade digna no cárcere garante que as mulheres permaneçam com seus filhos em âmbito prisional durante certo período de tempo. Esta situação, levando em consideração as condições das prisões brasileiras, induz ao questionamento sobre as circunstâncias as quais essas crianças se submetem quando permanecem com suas mães presidiárias, o que, por consequência, influi na análise do princípio da intranscendência da pena. Sob este enfoque, analisa-se a situação concreta do Estabelecimento Penal Irmã Irma Zorzi, fazendo-se, ao final, um contraponto entre o direito à maternidade digna no cárcere e o princípio da não transcendência penal, sob o escopo do conceito da antinomia jurídica. Para tanto, utiliza-se o método dedutivo acompanhado pela análise qualitativa da legislação sobre o tema, pela técnica documental em relação à observação de dados e pela técnica bibliográfica para caracterização dos conceitos jurídicos.

Published: July 2022

Este trabalho tem por objetivo obter evidências empíricas sobre a variação da produtividade do trabalho em cinco grandes setores da economia pernambucana durante os anos de 2010-2018, decompondo-a setorialmente com a técnica shift-share. O estudo traz trabalhos que utilizaram o método para analisar o Brasil após a abertura comercial nos anos 90 e outros que abordam outras regiões. A decomposição mostra que, mesmo com aumento da produtividade ao longo do período, as mudanças estruturais no emprego analisadas ano a ano, ocorreram mais no sentido de reduzir a produtividade do trabalho com deslocamentos da mão de obra de setores menos produtivos e com maior crescimento da produtividade para setores mais produtivos e com menor crescimento da produtividade.

Multi-omics analysis reveals a link between Brassica -specific miR1885 and rapeseed tolerance to low temperature
Authors: Xu Pengfei , Zhang Wenting , Wang Xuan , Zhu Yantao , Liang Wanqi , He Yuke , Yu Xiang
Published: July 2022

Brassica crops include various edible vegetable and plant oil
crops, and their production is limited by low temperature. The key
regulators of low-temperature resistance in Brassica remain
largely unexplored. To identify post-transcriptional regulators of plant
response to low temperature, we performed small RNA profiling, and found
that 16 known miRNAs responded to cold treatment in Brassica
rapa. The cold response of seven of those miRNAs were further confirmed
by qRT-PCR and/or northern blotting analyses. In parallel, a genome-wide
association study of 220 accessions of Brassica napus identified
four candidate MIRNA genes, all of which were cold-responsive, at the
loci associated with low temperature resistance. Specifically, these
large-scale data analyses revealed a link between miR1885 and the plant
response to low temperature in both B. rapa and B. napus.
Using 5′ rapid amplification of cDNA ends approach, we validated that
miR1885 can cleave its putative target gene transcripts,
Bn.TIR.A09 and Bn.TNL.A03, in B. napus.
Furthermore, overexpression of miR1885 in B. napus decreased the
mRNA abundance of Bn.TIR.A09 and Bn.TNL.A03 and resulted
in increased sensitivity to low temperature. Knocking down of miR1885 in
B. napus led to increased mRNA abundance of its targets and
improved rapeseed tolerance to low temperature. Together, our results
suggested that the loci of miR1885 and its targets could be potential
candidates for the molecular breeding of low temperature-tolerant
Brassica crops.
Intraoperative MRI for transsphenoidal resection of pituitary tumors: Community hospital experience
Authors: Onyewuenyi Alvin , Fishman Andrew , Chenelle Andrew , Masnyk Taras , Dewan Sheri
Published: July 2022

BACKGROUND: Intraoperative MRI (iMRI) is a definitive technology in
neurosurgery that has been used effectively to maximize outcomes for
transsphenoidal resection of pituitary tumors. IMRI has been seen to
provide optimal visualization of surrounding vital neurovascular
structures and has helped surgeons achieve gross total resection. The
use of iMRI in the community hospital setting has not been documented in
the current literature as of yet. OBJECTIVE: This study aims to provide
insight into the experiences of iMRI use in a community hospital setting
and add to the growing literature of iMRi use for transsphenoidal
resection of pituitary tumors. METHODS: A retrospective review of 56
patients who underwent iMRI guided transsphenoidal pituitary tumor
resection at Northwestern Medicine Central Dupage Hospital (from
November 2011 to April 2018) was performed. RESULTS: Gross total
resection was found in 67% (n=37) of patients who underwent iMRI. 33%
(n=19) did not achieve gross total resection of their pituitary mass.
IMRi was used exactly one time during the case in 96% (n=54) of
patients. IMRi was used more than once during the case in 4% (n=2) of
patients. Post operative tumor residual was found in 32% (n=6) of
patients who had available post-operative MRI studies (n=19).
CONCLUSIONS: Our study shows that iMRI can be useful in a community
hospital setting to achieve gross total resection during transsphenoidal
pituitary tumor resection. It also demonstrates the ability and need to
utilize iMRI only one time during a case which lends itself to operative
efficiency.
Research of black locust and common hackberry stands’ structure in Subotica-Horgos sands and proposed silvicultural measures aimed at their improvement
Authors: Andrasev Sinisa , Bobinac Martin , Susic Nikola
Published: July 2022

The paper analyzes the elements of the stand structure and proposes
silvicultural measures to improve conditions in the stand of black locust
(Robinia pseudoacacia L.) and common hackberry (Celtis occidentalis L.) aged
28 years in Subotica-Horgos sands. The research was performed on three
permanent experimental plots on which selective thinning (T1 and T2) was
performed experimentally in two plots, while one was left as a control plot
(C).Initially, 528 trees for tending per hectare were selected in the
studied age, of which 448 black locust and 80 common hackberry trees per
hectare were selected on T1, and 320 black locust and 208 common hackberry
trees per hectare on T2.In experimental plots T1 and T2 at least one
competing tree was cut down to each tree for tending, and a total of 912 and
1072 trees were cut down per hectare with a total volume of 53-55 m3?ha?1.In
this way, a basis was created for the assessment of the growth response of
trees to selective thinning in the upcoming period.
Tomographic changes after corneal collagen cross-linking for progressive keratoconus - one-year follow-up study
Authors: Petrovic Tiana , Stanojlovic Svetlana
Published: July 2022

Introduction/Objective. The aim of this study was to evaluate the outcome of corneal collagen crosslinking (CXL) in patients with progressive keratoconus. Methods. This retrospective single-centered interventional study included 52 eyes of 41 patients who underwent epithelium-off CXL procedure at the age > 18 years. Corneal tomography data, uncorrected, and best spectacle-corrected distant visual acuity (UDVA and CDVA, respectively) were analyzed at baseline and postoperatively over the initial 12-month period. In addition, the natural course of corneal tomographic changes was demonstrated at one, three, six, nine, and 12 months after the CXL procedure. Results. At one year, mean UDVA improved significantly from 0.15 ? 0.22 (0.3 min ? logMAR ? 0 max logMAR) at baseline to 0.06 ? 0.09 logarithm of minimum angle resolution (logMAR) (0.1 min logMAR ? 0 max logMAR) (p = 0.024). Mean CDVA was 0.45 ? 0.39 0.45 ? 0.39 logMAR (0.8 min logMAR ? 0 max logMAR) at baseline and 0.06 ? 0.13 logMAR (1 min logMAR ? 0 max logMAR) at one year (p = 0.039). Maximum keratometry showed a significant flattening of 1.36 D ? 1.53 D (p = 0.0032) at one year after CXL. Minimum keratometry significantly decreased with a mean change of 1.15 ? 1.20 (p = 0.011). Mean anterior and posterior best fit sphere (ABFS and PBFS, respectively) remained stable during the entire follow-up period. Mean reduction of corneal thickness after CXL was 47 ? 61 ?m (p = 0.003). At one year, 29 (56%) eyes showed K max regression, 22 (53%) showed stabilization, and one (2%) showed progression. Spearman correlation coefficients were calculated to assess the correlation between difference in preoperative corneal thickness (CT), in posterior elevation corneal thickness (PECT), and minimum corneal thickness, ?CT (PECT ? minCT) and radius difference ?r (r1-r2). Spearman rs > 0.3 proved statistical significance and correlation. Conclusion. In our study, CXL effectively prevented progression of keratoconus in 98% of eyes at one year, while improving visual acuity. The effect of CXL can be evaluated at the earliest after six months; at that time, the stability of the corneal shape was provided by following the CXL procedure. The main limitation of this study is the small number of patients included.
Clinical Utility of Cardiovascular Risk Scores for Identification of People With Type 2 Diabetes More Likely to Benefit From Either GLP-1 Receptor Agonist or SGLT2 Inhibitor Therapy
Authors: Sacre Julian W. , Magliano Dianna J. , Shaw Jonathan E.
Published: July 2022

OBJECTIVE

Differentiation of risk for major adverse cardiovascular events (MACE) from heart failure hospitalization (HHF) or kidney disease is important when selecting glucose-lowering therapy. We investigated the ability of separate MACE and HHF risk scores to 1) differentiate MACE from HHF risk; and 2) identify individuals more likely to benefit from either glucagon-like peptide-1 receptor agonists (GLP-1RAs) or sodium–glucose cotransporter-2 inhibitors (SGLT2is).

RESEARCH DESIGN AND METHODS

We identified three trials in type 2 diabetes that reported cardiovascular outcomes stratified by Thrombolysis In Myocardial Infarction Risk Scores for MACE and HHF. Pooled placebo-arm rates of HHF, MACE, and their ratio and estimated GLP-1RA– and SGLT2i-mediated reductions in events (MACE and HHF combined) were compared across cardiovascular risk strata in the trial populations.

RESULTS

The HHF rate was less frequent than MACE at all risk levels but increased from 18% of the MACE rate at low-intermediate HHF risk to 61% at highest HHF risk. Similarly, with increasing MACE risk, the incidence of HHF increased from 19% of the MACE incidence in those at low MACE risk to 51% in those with the highest MACE risk. Estimated GLP-1RA– and SGLT2i-mediated reductions in cardiovascular events were similar in those at low-intermediate MACE or HHF risk but tended to favor SGLT2is at higher risk levels of both scores.

CONCLUSIONS

A greater increase in the rate of HHF relative to MACE was observed with progressively higher cardiovascular risk, regardless of the risk score applied. Consequently, SGLT2is may offer greater overall cardiovascular protection in those at highest MACE risk, not just those at highest HHF risk.
Association Between Measures of Muscle Strength and Performance of Daily Activities in Patients with Knee Osteoarthritis
Authors: De Zwart Arjan , Dekker Joost , Verberne Simon , Roorda Leo D , Van der Esch Martin , Lems Willem F , Van der Leeden Marike
Published: July 2022

Objectives: Most studies of knee osteoarthritis use isokinetic peak strength as a measure of muscle strength. However, estimated one-repetition maximum (1-RM) may have a stronger relationship than isokinetic peak strength with daily activities. The aim of this study was to test the following hypotheses: first, the estimated 1-RM is more strongly associated than isokinetic peak strength with daily activities; and secondly, the estimated 1-RM is most strongly associated with the 6-minute walk test (6MWT), followed by the Get Up and Go test (GUG test) and the stair-climb test.Methods: Data were used for 177 patients with knee osteoarthritis from a randomized controlled trial on improving muscle strength. The patients had a mean age of 67.6 ± 5.8 years. Isokinetic peak strength was measured using a dynamometer, 1-RM was estimated with the 10-RM test, and physical performance was measured with the 6-minute walk test (6MWT), get-up and go test (GUG) test and stair-climb test, at the start and end of 12 weeks of resistance training. Linear regression analyses provided standardized betas (β) that were comparable between the different associations between measures of muscle strength and daily activities. Results: Compared with the estimated 1-RM, isokinetic peak strength was more strongly associated with all performance-based measures. The associations between the estimated 1-RM and performance-based tests were not ranked in the order hypothesized (6MWT, GUG test, stair-climb test).Conclusion: Contrary to the first hypothesis, isokinetic peak strength showed stronger associations with all daily activities than did estimated 1-RM. In addition, the second hypothesis regarding the activity-specific pattern for the 1-RM with regards walking, chair rising and stair climbing measurements was not confirmed.
LAY ABSTRACTIn patients with knee osteoarthritis, greater muscle strength in the upper leg is linked with better performance in daily activities. To test muscle strength, peak muscle strength is usually measured. This study hypothesized that another test (the one-repetition maximum test) would be a more relevant measure. However, this was not confirmed, and therefore peak muscle strength remains the best measure of muscle strength at present.

Men i Didaktisk dialog i högre utbildning händer det!" Läs Helene Edbergs recencion av boken Didaktisk dialog i högre utbildning (2021).
Intercultural Learning and Images in ELT: Exploring Cultural Imaginaries through Photographs
Authors: Brown Cecilie Waallann , Habegger-Conti Jena
Published: July 2022

This chapter presents an argument for the relevance of using photographs for intercultural learning in English Foreign Language (EFL) classrooms. More specifically, we suggest that by activating, expanding, and challenging the cultural imaginaries learners bring to and take from photographs, a more dynamic form of intercultural learning can be encouraged. A dynamic form of intercultural learning emphasizes the “inter” of intercultural and dismantles the dichotomy between “us” and “them”, making intercultural learning a personal and transformational process. Based on theoretical explorations and classroom experiences, we propose a set of general principles as well as three specific activities which have been implemented with secondary school and university-level learners. The activities all utilize photographs as prompts for reflective dialogues surrounding cultural imaginaries and aim to create complexity and multiplicity in the learners’ understanding of themselves and others. Encouraging this type of understanding is crucial given the increasingly complex and culturally diverse environments learners need to navigate in their everyday lives, formal education, and future work lives.

Authors: Rodrigues Cíntia Régia , Mailer Valéria Contrucci de Oliveira
Published: July 2022

Neste artigo, apresentam-se análises empreendidas de resultados de um estudo que procurou construir um panorama do desenvolvimento profissional do docente da rede pública estadual de ensino de um município de Santa Catarina. Ancorado em Imbernón (2011) e Nóvoa (1992), o desenvolvimento profissional relaciona-se a um conjunto de fatores que se articulam com o desenvolvimento pessoal do sujeito professor. Os dados foram levantados a partir de um questionário distribuído aos professores. Dessa forma, o trabalho tem como objetivo refletir sobre diversos aspectos que compõem o desenvolvimento profissional do docente, como: o perfil, a formação inicial e continuada, as práticas docentes e a compreensão dos documentos curriculares. Os resultados apontam para um descompasso entre formação e práticas docentes, bem como ausência de políticas públicas de carreira, formação continuada e melhores condições de trabalho.
RESEARCH ON THE RELATIONSHIPS AMONG INVESTMENTS IN SCIENCE, TECHNOLOGY & INNOVATION AND SOCIOECONOMIC DEVELOPMENT
Authors: Seibert Caroline Heidrich , Barros Neto João Pinheiro de
Published: July 2022

The purpose of this article is to correlate socioeconomic development indicators from a sample of fourteen countries, including Brazil, and the performance indicators in Science, Technology and Innovation CT&I. Statistical techniques of correlation between Science, Technology and Innovation indicators published by International Reference Institutions were used and the results showed high correlations between gross investments in ST&I and the Gross Domestic Product - GDP, as well as the position in scientific production (R2= 0.85 in both analyzes). The correlation between investments in CT&I and the competitiveness ranking was low; however, the innovation ranking showed a median correlation (R2 = 0.61) when related to the percentages of GDP invested in CT&I. The correlations between the innovation and competitiveness rankings with the HDI were also median (R2 = 0.61 and R2 = 0.56, respectively). The ST&I indicators were not correlated with GDP growth rates and unemployment rates. The study is limited to a sample of fourteen countries, chosen due to similarities with Brazil, but it can help in directing public policies for generating knowledge through investments in science, technology and innovation. The study is particularly important due to the indication that investments in knowledge generation (science, technology and innovation) do not necessarily decrease unemployment, but improve the HDI - Human Development Index.
PROFESSIONAL SKILLS OF THE FUTURE FOR STARTUPS IN SÃO PAULO
Authors: Augusto Eryka E. Fernandes , Roble Gilmara Lima de Elua , Fernandes Gabriel Paulino , Paulo Leonardo B. Henke de
Published: July 2022

The accelerated technological advancement has rapidly changed business models and the way companies think. In less than a century, we went through three industrial revolutions, which completely changed the panorama of the competences expected from an employee. In addition, the horizontal management models practiced by startups and their formula for accelerated growth meant that the skills from the beginning of the last century were no longer a reference today. The managers’ state that the jobs and companies of the future have not yet been created, working with the perspective of uncertainty and accelerated changes. These factors explain the need to understand what will be necessary for a worker to be considered qualified in the future. With that been said, the question of this research is "What are the important skills for startups to meet their requirements in 2025?” For that, we have chosen for a qualitative and exploratory research, given the lack of a theoretical framework on the theme. The result indicates that the skills demanded by startups are related to human skills, which are made up of actions such as initiative, creativity, solving complex problems, innovation and active learning.

Published: July 2022

The purpose of this article is presenting a reflection on Leadership Models and their positive or negative impacts on the quality of life of employees in the company. To carry out the study, the theoretical part and bibliographic research were initially started, thus having an approximation of concepts, in addition to the identification of key factors to be evaluated. A quantitative descriptive methodology was used with a survey applied to employees of companies in several different areas of work. The field research took place between June 25, 2019and July 3, 2019. Regarding the nature of the data, the method used was an exploratory research with 20 questions on the subject of Leadership Models and the impacts on the quality of life of the worker. Questions were selected regarding the type of market the worker works in, gender, types of leadership, and autonomy at work, incentives and quality of life. The results show that it is possible that the leadership model has a significant impact on the quality of life at work and that even workers having access to their leaders most of the time and even having incentives at work, believe that the participatory leadership model interferes positively in the perception of quality of life at work.

Authors: Abbud Ricardo Hares , Grander Gustavo , Silva Luciano Ferreira da
Published: July 2022

The purpose of this article was to identify the relationship between motivation and engagement and project management. For that, we performed a cluster analysis with 529 articles. As a result of this research, the increase in the number of publications and the formation of 5 large groups that indicate different discussions on the theme, with emphasis on sustainability and local participation of interested parties, were evidenced, suggesting that these factors impact on the motivation of project teams. This research contributes to studies on motivation by pointing out its relationship with other issues of importance for project management with greaterefficiency and effectiveness.
cost-effectiveness of fibre optic technology deployment in rural area
Authors: Oki Olukayode , Lawrence Morolake Oladayo
Published: July 2022

Studies have shown that the majority of the global population are migrating from rural to urban areas. People are leaving rural areas due to poor services such as poor broadband service. Fibre optic technology has been introduced as a solution to poor broadband quality. However, as a result of the peculiar characteristics of South Africa's rural areas, the majority of the telecommunication operators are hesitant to invest in ICT in rural areas because it tends to be much less profitable. Hence, the study of how cost-effective it would be to deploy a fibre optic network in rural areas as compared to the current wireless (LTE) network remains an open issue. This study investigates the cost-effectiveness of deploying a fibre optic network in the rural area of Mdantsane township, by analysing the installation and operation costs of fibre optic networks in comparison to the cost of wireless (LTE) networks. The finding of the study amongst others showed that while fibre optic networks seem to be great, however, they come at a cost. The cost of drilling and trenching associated with the deployment of fibre optic networks was reported as the key reason why the network deployment is costly. Hence, reducing the cost of drilling and trenching would reduce the cost significantly. The study suggests that, to lower fibre optic deployment costs, network operators should collaborate and share costs through a customised pricing model that benefits both the operators and rural internet users.

Published: July 2022

Devido à escassez de água e da preocupação com a sua existência no futuro, há necessidade de aprimorar os sistemas de gestão e de apoio à decisão para que a água não venha faltar. Quando se fala em processo decisório, não há como concebê-lo sem o uso de Tecnologias da Informação e Comunicação (TIC). Além das existentes, duas TIC emergentes parecem ser úteis nesse processo, a Internet das Coisas (IoT) e o Big Data. Assim, esse trabalho tem como objetivo verificar como o uso de Tecnologias da Informação e Comunicação, principalmente IoT e Big Data, podem auxiliar o processo decisório na gestão dos recursos hídricos em bacias hidrográficas. O presente estudo caracteriza-se como uma pesquisa exploratória, de caráter qualitativa e prescritiva. Como resultado, pretende-se relacionar esses conceitos e apresentar como as TIC podem auxiliar na gestão dos recursos hídricos em bacias hidrográficas.
Missa do Galo de Machado de Assis e a Avaliatividade Implícita
Authors: Montinegro Maria do Socorro Suzano
Published: July 2022

Missa do Galo, conto de Machado de Assis, trata do diálogo entre Nogueira, um jovem pensionista, e Conceição, a hospedeira, em uma noite de Natal em que uma simples conversa pode apresentar um jogo sublime e indireto, aparentemente banal, mas que intriga Nogueira. Este estudo apoia-se Na Linguística Sistêmico-Funcional, que oferece um instrumento analítico específico para o exame sistemático das motivações, propósitos, suposições e interesse dos produtores do texto e tem como objetivo a análise crítica das escolhas lexicogramaticais feitas no conto a fim de desvendar o que subjaz ao diálogo entre as personagens.
