Published: January 2021

The title of this paper is The Analysis of Conflict of the Main Character in the Movie “I am Sam”. This study focuses on describing the category and function of the main character and the external conflicts of the main character. The movie I am Sam was analyzed by categorizing the main character. The data of this study were taken from a movie entitled I Am Sam. The data were collected through documentary method, by watching the movie and were then by marking and taking notes of parts of the movie which are related to the study. The data then were categorized based on the theories. The American drama film I am Sam which is the compelling story of Sam, a mentally-challenged father raising his daughter Lucy with the help of a unique group of friends. The category and function were analyzed based on the theory proposed by Wellek and Warren (1995: 227) who divide character into two types, static and dynamic characters; the analysis also included Protagonist and Antagonist characters. The conflict was analyzed based on the theory of literature proposed by Kenney (1996) who divides conflicts into two types, external and internal conflicts. But in the movie, the only external conflict occurs. The analysis brought some conclusions. Sam, as the main character, has a mental disorder, described as a really kind-hearted person. He also had a big willing, even so many challenges he should pass to live with his daughter, he still tried so hard to do it. After so many people hurt his feeling, he was still kind and did not do bad things to them. The conflicts all passed with him being a kind and honest person.

The Role of Quality Management System in Promoting Innovation in Companies
Authors: Marouane Saadia
Published: January 2021

This article makes it possible to verify the role of quality management in strengthening the innovation process. The first hypothesis, according to which the quality (certification ISO 9001) influences the innovation positively, is confirmed for certain innovation indicators. Another hypothesis indicates that there are the levels of quality which develop the innovation process in diverse ways. The results indicate that for some domains of innovation, the performance of innovation of enterprises that have a very increased level of quality is higher than those of enterprises with an average quality, which in return is higher than those enterprises having a low quality level. Therefore, we discovered that the difference of performance innovation among enterprises having an average quality and those having a low level quality is not significant. This study suggests, thus, that in order to significantly ameliorate its innovation performance, the company must possess a quality system that is solidly established.
Highly-Performed Fuzzily-logicized Edge Detecting Algorithm for Noisy Handwritings
Authors: Sami Hasan  , Shereen S. Jumaa
Published: January 2021

The main targets for using the edge detection techniques in image processing are to reduce the number of features and find the edge of image based-contents. In this paper, comparisons have been demonstrated between classical methods (Canny, Sobel, Roberts, and Prewitt) and Fuzzy Logic Technique to detect the edges of different samples of image's contents and patterns. These methods are tested to detect edges of images that are corrupted with different types of noise such as (Gaussian, and Salt and pepper). The performance indices are mean square error and peak signal to noise ratio (MSE and PSNR). Finally, experimental results show that the proposed Fuzzy rules and membership function provide better results for both noisy and noise-free images.

Authors: Kędzia Bogdan , Hołderna-Kędzia Elżbieta
Published: January 2021

The pharmacological tests presented in the first part of this work clearly indicate the beneficial effect of propolis extracts and their components on the heart and blood vessels. The propolis extracts and the components present in them, such as caffeic acid phenylethylester (CAPE), artepillin and pinocembrin, are characterized by multidirectional effects on the heart and blood vessels. The publications cited earlier indicate that propolis extracts direct impact on the heart, and confirmed anti-ischemic activity, diastolic blood vessel activity, preventing hypertrophy of vessels, inhibiting blood capillary permeability, lowering blood pressure, preventing cardiomyopathy as well as hypolipemia. This part of the paper discusses anticoagulant, anti-angiogenic activity of propolis extracts and prevention of ischemic necrosis of the brain tissue. On the basis of the provided pharmacological research data, it can be assumed that the described properties of propolis extracts and substances isolated from them will contribute to the application of these products in the treatment of heart and blood vessel diseases.
Local competing in interpolation problems
Authors: Znamenskij Sergej Vital'evich
Published: January 2021

A simple example illustrates the insufficiency of the known approaches to interpolation in the problem of recovering a function from a few given specific values that clearly convey the form.

A local choice between polynomial and rational local interpolants, which minimizes the local interpolant’s errors at the nearest external nodes from one or different sides, complements the known approaches. It combines the extreme computational simplicity of local interpolants with the thorought selection of them.

The principles of constructing the algorithm are formulated in general terms for mappings of metric spaces. They provide accurate (with rare exceptions) reconstruction of mappings that locally coincide with some of the given possible interpolants.

In the one-dimensional case, the two-stage algorithm guarantees the continuity of the interpolant and accurately reconstructs polynomials of small degree, simple rational functions with a linear denominator, and broken lines of long links with knots at the ends when these requirements do not contradict each other. An additional parameter allows you to replace the exact restoration of polylines with the required smoothness of interpolation.

Background:

Melanocytomas are rare pigmented tumors of the central nervous system (CNS). They are more frequent in females in their fifties and are typically benign, but locally aggressive lesions that very are rarely found in the spine. They can occur in all the age groups.

Case Description:

A 62-year-old male presented with acute paraplegia a attributed to a C7-T1 intradural extramedullary melanocytoma. Urgent surgery, consisting of subtotal removal of the lesion, resulted in subtotal recovery of motor function with full resolution of his sensory deficit. Histologically, the lesion proved to be a melanocytoma.

Conclusion:

Rarely, patients with intradural extramedullary melanocytomas of the spine may present with acute paralytic deficits warranting emergent surgical intervention.
Localized Active Space Pair-Density Functional Theory
Authors: Pandharkar Riddhish , Hermes Matthew R. , Cramer Christopher J. , Truhlar Donald G. , Gagliardi Laura
Published: January 2021

Accurate quantum chemical methods for the prediction of spin-state energy gaps for strongly correlated systems are computationally expensive and scale poorly with the size of the system. This makes calculations for many experimentally interesting molecules impractical even with abundant computational resources. In previous work, we have shown that the localized active space (LAS) self-consistent field (SCF) method is an efficient way to obtain multi-configuration SCF wave functions of comparable quality to the corresponding complete active space (CAS) ones. To obtain quantitative results, a post-SCF method is needed to estimate the complete correlation energy. One such method is multiconfiguration pair-density functional theory (PDFT), which calculates the energy based on the density and on-top pair density obtained from a multiconfiguration wave function. In this work we introduce localized-active-space pair-density functional theory, which uses a LAS wave function for subsequent PDFT calculations. The method is tested for computing spin-state energy gaps in conjugated organic molecules and bimetallic compounds and is shown to give results within 0.05 eV of the corresponding CAS-PDFT results at a significantly lower cost.
Systematic Study of the Thermal Properties of Zeolitic Frameworks
Authors: Ducamp Maxime , Coudert François-Xavier
Published: January 2021

We report a systematic study of the thermal and mechanical properties of 134 pure SiO2 zeolites through DFT-based calculations by making use of the quasi-harmonic approximation (out of a total of 242 known fully ordered zeolitic frameworks). The comparison of our results with reported experimental data for several zeolites revealed a very good accuracy and validated our simulation methodology. We observe a wide range of thermal expansion coefficients (from −5 to −35 MK−1), highlighting the great influence of the framework topology over this physical property, while demonstrating that all pure-silica zeolites exhibit negative thermal expansion (NTE). Our simulations also provide a path for the computation of the bulk modulus for each structure, as well as its pressure and temperature dependence. Results revealed a large gamut of bulk modulus values (from 8 to 134 GPa), showing that most frameworks display pressure-induced softening — but not all! Finally, this study provides some hints to the open question of experimental feasibility of zeolitic frameworks, showing that the experimentally synthesized structures appear to have a distinct distribution of thermal and mechanical properties.

Asparagus brachyphyllus Turcz. is a rare species in Russia. It’s a herbaceous perennial plant with short horizontal rhizome which gives 1-6 annual shoots. According to the literature the species grows in saline steppe and around salty lakes. In conditions of Eastern Transbaicalia vegetation lasts a little more than four months from middle May to late September, fruiting from June to September. A. brachyphyllus is listed in Red Book of Russian Federation, it is protected in Daursky State Nature Biosphere Reserve. In Transbaicalia it is limitated by small area of habitats, narrow environmental tolerance, low numerity of populations, grazing (annual shoots are eagerly eaten by animals, especially in spring). A. brachyphyllus has eastern-asian steppe (in the narrow sense) type of distribution, the main part of area is in North-East of China and in the East of Mongolia. In Russian Federation it occurs only in steppe districts of Zabaikalsky kray where there is the northern distribution limit. During our many years field expeditions new localities of A. brachyphyllus in Zabaikalsky Region were descripted, information on ecological-phytocenotic features and populations condition at the northern area limit was expanded. Localities of the species were identified at South and South-East of Zabaikalsky kray: Argun area, Aga steppe and Torey lake surroundings; most of localities are concentrated near Torey lakes, in other areas localities are sporadic. A. brachyphyllus grows mostly in Achnatherum splendens and Achnatherum splendens – Leymus chinensis saz steppe communities on solonetz soils, also on soil complexes of solonez and solonchack, sometimes it occurs on solonchacks in hyperhalophytic communities with Kalidium foliatum, Limonium aureum, Suaeda corniculata, Puccinellia tenuiflora. In plant communities A. brachyphyllus appears as a species with low abundance and coverage less 1%; due to prostrate form of shoots they place in lower layer up to 10 cm. In few-species communities on solonchacks A. brachyphyllus has low abundance, and a little higher on solonetz. In last case both species number and density of asparagus coenotic population are higher as usual. For estimation coenotic populations vitality we used a complex of criteria: density of coenotic populations, projective cover of species, markers of generativeness. Numerous Torey coenotic populations most often have medium vitality while that of coenotic populations at Aga localities higher. About a half of revealed coenotic populations suffer temperate influence of livestock grazing which lessens vitality by trampling and partial eating. Some localities at Torey lakes area need special protecting measures.

Wild ginseng Panax ginseng C. A. Mey. (Araliaceae) is a rare medicinal plant. The aim of this work is to assess the state of ginseng cenopopulations in the Ussuriysky State Nature Reserve, and to search of indicator species of its optimal habitats. The reserve is located on the southern spurs of the Sikhote-Alin ridge in the basins of the Artyomovka and Komarovka rivers. In the course of route studies in the period from 2012 to 2019, phenological observations, description of habitats, determination of the age status and morphometry of 77 plants found in 8 types of forest were carried out. A large part of the finds belong to the cedar forests hornbeam – 44.4 %. Analysis of the species composition of the immediate environment of the relic, performed on 36-meter sites, revealed 41 species of vascular plants. Based on the generalized analysis of author's and literature data, a list of 7 species–indicators of optimal habitats for ginseng reintroduction was selected: Oxalis acetosella, Phryma asiatica, Hylomecon vernalis, Thalictrum filamentosum, Maianthemum bifolium, Galium davuricum, Carex ussuriensis. The number and composition of associated species varies depending on the type of forest. Long-term observations carried out in the reserve have revealed significant changes in the phenology of P. ginseng. In recent years, there has been a shift in the beginning of the growing season, flowering and ripening of fruits to earlier dates. Modern findings of ginseng in atypical habitats are described, indicating a broader ecological amplitude of its growth than was indicated by the first researchers. The age composition of the population is normal, but incomplete, there are no senile, very few mature generative plants, the rise falls on the group of medium-generative plants. In order to construct a vitality spectrum, plants from the most numerous age group in the generative middle-aged state g2 (n = 22) are ranked according to stem height into three vitality classes: higher (> 55 cm), medium (35-55 cm) and lower (< 35 cm). Frequency distribution analysis revealed predominance plants of the higher and middle classes of vitality. The vital spectrum indicates the equilibrium state of the population. Good fruiting and renewal of ginseng indicates the preservation of the species in the protected area, and the compliance of modern conditions of natural habitats to its ecological optimum.

The Possible Molecular Mechanism of SARS-CoV-2 Main Protease: New Structural Insights from Computational Methods
Authors: Tasneem Alvea , Rai Gyan Prakash , Reyaz Saima , Bairagya Hridoy R.
Published: January 2021

Main protease (Mpro) is one of the key enzymes in the life cycle of SARS-CoV-2 that plays a pivotal role in mediating viral replication, transcription, and makes it an attractive drug target for this virus.  The catalytic site of this enzyme comprises of a dyad His41 and Cys145 and lacks the third catalytic residue, which is replaced by a stable water molecule (W). The computational structural analysis on crystal data for Mpro protein suggests that W1, W2, His163, and Tyr161 may also play a vital role in the activity of this enzyme and they may act as catalytic partners along with Cys(145)-His(41) catalytic dyad. The thiolate–imidazolium ion-pair between Cys145 (-SH---NE2-) His41 and Cys145 (-SH---NE2-) His163 have been stabilized by W1 (with W2) and Tyr161, respectively. Therefore, unique interactions of W2---W1---ND1-His41-NE2---SH-Cys145 or Cys145-SH---NE2-His163-ND1---OH-Tyr161 in Mpro serve as an excellent drug target for this enzyme and suggest a rethink of the conventional definition of chemical geometry of inhibitor binding site, its shape, and complementarities. Our computational hypothesis suggests two essential clues that may be implemented to design a new inhibitor for Mpro protein. The strategies are: (i) ligand should be occupied either W1 or W2 or both of these position to displace these water molecules from the catalytic region, and (ii) ligand should be made H-bonds with Cys145 (-SH), His41 (NE2/ND1) and His163(NE2) to inhibit Mpro. The results from this computational study could be of interest to the experimental community and also provide a testable hypothesis for experimental validation. Doi: 10.28991/SciMedJ-2020-02-SI-11 Full Text: PDF

Penser au-delà du binarisme: Étude des stratégies de reconnaissance et de ré/conciliation des altérités dans « Aux États-Unis d’Afrique » d’Abdourahman Waberi
Authors: Boum Make Jennifer
Published: January 2021

Dans  « Aux États-Unis d’Afrique » (2006), Abdourahman Waberi renverse le monde et instaure de nouveaux rapports de force. L’espace géographique alors renommé Etats-Unis d’Afrique, est une fabrique du pouvoir politique, social et culturel qui domine le Nord géographique des dépossédés. Dans le récit, la mise en place d’un patrimoine culturel africain suggère en premier lieu le dépouillement de ceux associés à d’anciennes puissances coloniales et dans en second lieu, une pratique conjointe de destitution et de restitution du nom. Le Nord de l’envers et les États-Unis d’Afrique de l’endroit sont non seulement les vecteurs de rapports de domination mais tracent plus précisément les contours d’un binarisme: le Sud géographique impose l’hégémonie africaine au reste du monde. Au coeur de cet espace mondial redessiné, Maya/Malaïka (prénom d’adoption), personnage central du récit, est en mouvement; quittant les États-Unis d’Afrique en quête de ses origines, elle se met en route vers le Nord, et prend le chemin du re(/dé)tour dans les dernières pages du récit.
S’agirait-il là de la subversion du binarisme géographique, d’une distortion d’un modèle d’espace frontalier figé par le biais du motif de l’errance ? Ainsi, en quoi peut-on déceler dans l’oeuvre de Waberi plusieurs niveaux de déstabilisation de toute proposition binaire, qui atteignent leur culmination avec le motif de l’errance ? Dans quelles mesures, le voyage de Maya tend vers une remise en question des moules identitaires géographiques et culturels, et à quels effets ?

Published: January 2021

Introduction: Mammography (MMG) reduces breast cancer mortality. Positioning is a critical factor for the quality of the test. Objective: To evaluate a positioning training program (PTP) to improve MMG quality. Methods: This is a case-control study of an MMG PTP. This study was performed in a private service specialized in breast diagnosis. We evaluated 200 projections from 50 MMGs carried out by two experienced technicians (6 years and 17 years of practice) – 25 screenings each. Performance criteria were evaluated in the mediolateral oblique (MLO) and craniocaudal (CC) views. In CC, we considered adequate positioning a good projection of outer quadrants (OQ), visualization of the pectoralis major (PM), centered nipples (CN), good projection of inner quadrants (IQ), no folds or creases, nipples in profile, and symmetrical breasts (SB). The low positioning of the Bucky was considered an error criterion. In the MLO evaluation, the criteria for an adequate positioning were the visualization of inframammary angles (IMA), nipples in profile and at the PM level, SB, no folds or creases, and symmetrical PM. Hanging breasts and visualization of the pectoralis minor (Pm) were considered positioning failures. An 11-hour theoretical and practical training was provided: 7 hours of practice and 4 hours of theory; new tests were performed, and the quality criteria were evaluated. Results: Positioning errors significantly decreased after the PTP. CC errors dropped from 39% to 11%. MLO errors decreased from 36% to 13%. After the PTP, the CC criteria evaluated improved: good projections of OQ – from 50% to 94%; visualization of the PM – from 21% to 62%; CN – from 49% to 79%; good projections of IQ – from 45% to 100%; lack of folds or creases – from 74% to 88%; nipples in profile – from 91% to 95%; SB – from 86% to 98%. The low positioning of the Bucky dropped from 19% to 0%. The MLO criteria evaluated also improved after the PTP: visualization of IMA – from 45% to 82%; nipples in profile – from 93% to 95%; nipples at the PM level – from 24% to 84%; lack of folds or creases – from 39% to 70%; SB – from 90% to 100%; symmetrical PM – from 56% to 82%; symmetrical nipples – from 72% to 86%; visualization of the Pm – from 13% to 7%. Conclusions: The MMG PTP improved the quality of the test, the gold standard in the early detection of breast cancer. PTP acts in a vulnerable part – the human. The results indicate that a simple and low-cost intervention of low technological complexity can significantly affect the quality of MMGs and screening programs in our country.

Introduction: There are no randomized studies that assess the role of risk-reducing mastectomy in decreasing the mortality of mutated patients; however, major prospective studies show a decrease in the incidence of breast cancer. The absolute reduction in the risk of breast cancer ranges from 2% to 7%, but the reduction of the risk of developing breast cancer is higher than 90%. The increasing mortality caused by contralateral breast cancer in the mutated patient is 1.7%, in 10 years, and 6.8%, in 20 years. Objectives: To analyze the cases of risk-reducing mastectomy in patients with BRCA mutation. Method: This is a retrospective study. We included all patients who had positive BRCA mutation test, assisted from 1999 to 2019. The study was approved by the Research Ethics Committee of Universidade Federal do Piauí, report n. 2.817.502. Results: We studied 23 patients who had a mutation in the BRCA gene, being 15 (65.2%) in BRCA 1, and 8 (34.8%) in BRCA 2. All participants were female, with mean age of 46 years, and mean of three cases of cancer in the family. Seven (30.4%) risk-reducing bilateral or contralateral mastectomy procedures were performed. The mean age at the performance of surgery was 38 years. There were six cases of previous breast carcinoma in one of the breasts, and one patient who had not been diagnosed with breast cancer. All of them were submitted to immediate reconstruction with inclusion of a silicone prosthesis. Laparoscopic bilateral salpingo-oophorectomy was performed in three patients. The histological type in the six patients with cancer was invasive carcinoma of no special type, being four triple negatives. Neoadjuvant chemotherapy was performed in four cases; in 6 cases, the mutation was in BRCA1. All patients remain without complains and free of disease, with mean follow-up of 29.5 months. Twelve (52.1%) patients are being followed-up with mammography, resonance and annual clinical examination, and did not accept risk-reducing mastectomy or salpingo-oophorectomy. Conclusions: Risk-reducing mastectomy was performed in 30.4% of the patients with deleterious mutation of BRCA. The main mutation was BRCA, and in 85.7% of the cases, the patient presented with previous breast cancer in one of the breasts.
Breast cancer in patients with brca mutation: case series
Authors: Vieira Sabas Carlos , Fontinele Danilo Rafael da Silva
Published: January 2021

Introduction: Women who inherit a deleterious mutation in BRCA face substantially increased risks of developing breast cancer, estimated in 70%. Even though the annual screening with magnetic resonance and mammography promotes the early detection of the disease, the gold standard for the primary prevention of breast cancer is still bilateral mastectomy. Objectives: To characterize breast cancer with mutation in the BRCA gene. Method: This is a retrospective study, case series. We included all patients who had tested positive for BRCA mutation and who had a previous or current diagnosis of breast cancer from 1999 to 2019. The study was approved by the Research Ethics Committee of Universidade Federal do Piauí, report n. 2.817.502. Results: We found 10 patients with previous breast cancer, or at the time when they had a mutation in the BRCA gene. They were all female, with mean age of 39.4 years at diagnosis, average of 3.6 cases of cancer in the family. Five (50.0%) were triple negative tumors, mean size of 6.7cm, 9 invasive carcinomas, 2 stage IIIB, 3 cases with invasion and impairment of axillary lymph nodes. Three underwent bilateral salpingo-oophorectomy, and 6 underwent bilateral or contralateral risk-reducing mastectomy procedures. All patients were submitted to chemotherapy, being 6 neadjuvant and 5 associated with radiotherapy. As to type of mutation, 6 presented mutation for BRCA1, and 4 for BRCA2. Two patients died because of the disseminated disease. Only one patient is still being followed-up, after 29 months, with annual mammography, resonance and clinical examination, and did not accept risk-reducing mastectomy or salpingo-oophorectomy. Conclusions: The mean age of breast cancer diagnosis was 39.4 years. Half of the patients were triple negative, and most had mutation in BRCA1. Two patients died because of the disseminated disease.
Anaphylactic reaction to patent blue dye during sentinel lymph node biopsy in breast cancer

Published: January 2021

Introduction: Sentinel lymph node biopsy is indicated as gold standard in the surgical treatment of initial breast cancer, presenting as a more conservative approach and preventing total lymphadenectomy. Dyes or technetium radiopharmaceuticals can be used to identify the sentinel lymph node. The most used dyes for the identification of the sentinel lymph node are patent blue and isosulfan blue, and, in lower frequency, methylene blue. However, hypersensitivity reactions to blue dye have been described, estimating its prevalence in 0.6%‒2.7%. The clinical status that characterizes the allergic reaction to the dye can range from mild skin changes to the severe condition, with circulatory collapse. Objectives: To present a severe case of allergic reaction to patent blue in a patient submitted to surgical treatment for breast cancer. Method: This is a case report study based on the analysis of medical records and literature review. Case report: T.L.O.M, female, 49-year old woman, white, married, born in Patos de Minas, MG. Patient diagnosed with Breast cancer, T1N0A0, with indication for sentinel lymph node analysis with blue patent and segmental resection of the tumor. ASA 1 pre-anesthetic evaluation, without history of allergy. The patient was submitted to general inhalation anesthesia and subcutaneous injection in the left breast of 2ml of patent blue, followed by massage. During the anesthetic plan, after 40 minutes of surgery, the patient was hypotensive (40x20 mmHg), with low saturation (ETCO2 28), tachycardia (120 bpm), associated with bluish urticariform papules, and major edema in the ear lobes, being immediately assisted with adrenaline bolus, metaraminol, and decadron. The patient became stable, and it was possible to conclude the procedure. Then, she was referred to the intensive care unit, under sedation and intubated due to the risk of laryngospasm. She evolved hemodynamically stable, and was extubated without intercurrences. Conclusions: A severe anaphylactic reaction to patent blue can risk the life of a patient in an unpredictable manner. Considering this case, it is essential that the entire staff involved in the sentinel lymph node biopsy be aware of the possibility of a hypersensitive reaction to the dye, being prepared to recognize and immediately handle the possible repercussions.

Introduction: Early exercises in the postoperative period of breast cancer are important to prevent motor and functional complications 1,2. However, there are no prospective studies with protocols including specific exercises for patients submitted to breast oncoplastic surgery. Objectives: To assess the amplitude of movement, pain and upper limb function; incidence of dehiscence, seroma, infection and necrosis; and occurrence of reoperation in women in the postoperative period of oncoplastic breast cancer surgery, who underwent protocol of postoperative exercises with restricted shoulder movement for 15 or 30 days. Methodology: We included 60 women with breast cancer submitted to conserving surgery using the oncoplastic technique. They were assessed in the preoperative period and 07, 15, 30, 60 and 90 days after surgery. On the day after the surgery, all patients initiated an exercise protocol limited to 90 degrees, guided by the physical therapist, and performed at home. Two weeks after the surgery, they were randomized in two groups: Amplitude Free Group (30 patients) – liberation of shoulder joint amplitude at the pain threshold or until the sensation of displacement in surgical borders; Limited Amplitude Group (30 patients) – maintenance of shoulder movement restricted to 90º until 30 days after the surgery, when they were also cleared to do free amplitude exercises. Results: there were no differences between groups regarding shoulder joint amplitude, pain and function of upper limbs. In the intragroup analysis, only the Limited Amplitude Group presented upper limb functional index worse than in the preoperative period. There were no differences between groups regarding the incidence of postoperative scar complications nor the need for reoperation. Conclusion: the free amplitude exercises 15 days after the surgery did not have an impact on the movement amplitude nor on the pain, with beneficial effect only in the intragroup analysis, regarding upper limb function. It was considered safe in relation to scar complications.
Interview during the Russian language Basic State Exam: Interpretation of assessment criteria
Authors: Maslova M. V.
Published: January 2021

This paper sets out to clarify the criteria «Performance of a communicative task» and «Ability to consider the conditions of a speech situation» used for assessing the dialogue assignment at the Basic State Exam interview in the Russian language, as well as to outline directions for training conversational vocal responsiveness. The applied methodology included a correlation and discourse analysis of 9th-grade Russian students’ responses to the questions of the interlocutor-examiner, as well as a review of research and methodological sources. The author of the paper postulates that the fulfilment of the first criterion – «Performance of a communicative task» – entails an adequate interpretation of the question and consequent formulation of a detailed vocal response correlating with the question. A correlation analysis of interviews revealed that students’ inability to interpret questions and their insufficient apperception base generate such errors as violation of the subject domain of the question, question substitution, violation of the theme-rhematic structure of the answer, tautological character of the answer, poorly defined nominal group in the answer, absence of an answer to one of the questions in the series (question pair), formalistic answer. The second assessment criterion «Consideration of the conditions of a speech situation» – is correlated with the recipient factor, expressed in the speech code through the speaker’s performance of rapport-building and metalinguistic speech actions. A discourse analysis of interviews showed that students use numerous non-speech and nominal-speech units in their responses, which enable them to regulate their own mental activity, but appear to be invalid in terms of organising their speech with regard to a recipient. Vocalised pauses, puffs of sounds and filler phrases in the responses indicate tense speech production and a low level of lamprophony, thus making such responses difficult for the examiner to perceive. On the basis of the proposed interpretation of the criteria used for assessing dialogue speech, the author postulates the necessity of training speech responses in a dialogue situation, which can be organised in the following areas: 1) enrichment of the apperception base; 2) training the interpretation of interrogative statements; 3) teaching rapport-building and metalinguistic speech actions aimed at regulating mental activity and considering a recipient. The obtained results can be used for improving the methodology of preparing students for task 4 of the final interview in the Russian language, strengthening the continuity of training for interview at the 9th and Unified State Exam at the 11th grade.
