ПРОБЛЕМА ВИБОРУ МЕТОДУ МІКРОЕКОНОМІЧНОГО ДОСЛІДЖЕННЯ ДЛЯ МЕНЕДЖЕРА
Authors: Панченко В. А.
Published: October 2021

В статті докладно проаналізовано, які існують на сьогоднішній день методи наукових до-сліджень. У результаті проведеного дослідження автором виявлено, що загальні методи наукових досліджень не всі підходять для економічної теорії. Це може призвести до перекручування результатів, неправильного тлумачення виявлених факторів. Визначено основні наукові категорії мікроекономіки: “метод економічного аналізу”, “методика проведення економічного аналізу”. Метою статті є провести науковий аналіз та порівняння існуючих методів економічних досліджень і вибрати такий метод чи групу методів, які б найкраще підходили для проведення мікроекономічних досліджень і достовірності аналітичних результатів. Встановле-но, що мікроекономічні дослідження розпочинаються зі збирання та вивчення фактів економічного життя, а дослідження причинно-наслідкових зв’язків дає змогу встановити мотиви поведінки економічних суб’єктів та побудувати модель. Визначено, що метод економічного аналізу – сукупність прийомів та способів дослідження господарської діяльності будь-якого економічного об’єкта шляхом виявлення та визначення впливу окремих факторів і параметрів, кількісних та якісних змін економічних показників у часі. З’ясовано, які застосовують методи економічних досліджень для побудови економічних моделей, та запропоновано групу спеціальних ме-тодів досліджень як найбільш достовірний інструментарій проведення мікроекономічних досліджень. Доведе-но, що для мікроекономічних досліджень доцільно використовувати групу спеціальних методів дослідження. До спеціальних методів дослідження відносять: методи збору інформації; методи обробки інформації; мето-ди проведення аналітичної роботи; методи планових розрахунків і обґрунтувань; методи прогнозування. Спеціальні методи дослідження, які будуть використовуватися при проведенні мікроекономічних досліджень, базуються на економіко-математичному аналізі та математичному програмуванні. Розглянуто основні еко-номічні моделі фірми, які ґрунтуються на мікроекономічних показниках: “модель максимізації продажів”, “модель максимізації зростання бізнесу”, “модель управлінської поведінки”.

The Gravitational Fields of J.M Coetzee’s Fiction
Authors: ELGARHI Nabit
Published: October 2021

The novels of J.M. Coetzee, South African novelist, have always been a source of inspiration for both readers and critics. A distinctive feature of his writing is the ability to converse with a wide range of disciplines amongst which is the scientific field stands distinguishingly appealing. This paper will explore the use of cosmology terminology to see its underpinnings in J.M Coetzee’s fiction as well as in Derek Attridge’s insightful criticisms. The gravitational velocity of J.M Coetzee’s fiction stems from his text’s singularity. Singularity remains Coetzee’s hallmark to engage with ethics and politics of otherness. The deconstruction of the simplistic and the normative comprehensions of post-apartheid establishes Coetzee’s singularity as his ethical defense of the singularity of literature on a large scale.
A Quasi-experimental Study on the Impact of BlendedLearning on EFL Students’ Language Proficiency
Authors: BENHADJ Yassine
Published: October 2021

The study aimed at examining the effect of adopting blended learning on Moroccan high school students’ English language proficiency. This has been essentially achieved through relying both on face-to-face classroom interactions and using “Google classroom”, which is a free online learning platform.  The researcher opted for a quasi-experimental design to gauge the impact of implementing a blended learning model on the research sample. This study enlisted the participation of 79 Moroccan first-year Baccalaureate students who were divided into two separate but homogenous groups. The experimental group was taught using the blended learning model, and the control group was tutored in a traditional learning environment. The mean scores’ differences of the pre-test and the post-test asserted that, in comparison to the face-to-face learning, the blended learning model adopted was significantly impactful in improving the language proficiency level of the treatment group. However, no significant gender differences were observed in this regard. In essence, this piece of research has placed much emphasis on the idea that the efficient incorporation of ICT, particularly blended learning, into the learning/teaching process can help satisfy students’ needs, increase their motivation, and eventually enhance their language mastery.
TED Talks as a Listening Resource in the EFL College Classroom
Authors: Al-Jarf Reima
Published: October 2021

The article proposes a model for integrating TED Talks (TTs) in EFL college listening practice. It shows instructors where TTs can be located, gives reasons for using TTs, criteria for selecting TTs, the listening skills that can be developed, and an instructional strategy. TTs provide a variety of real-life themes, speakers, motivation, and inspiration. They save instructors’ time and effort as they are available on You Tube, mobile apps or in the TED website. In selecting TTs, the instructor should take into consideration the students' interests, difficulty level of the TT language and content, its length in minutes, and speed and accent of the speaker. Before watching a TT, she posts the title of the TT on an LMS or social media platform. She sets goals for listening and gives pre-questions to help the students comprehend the TT content. The students view the TTs on their smart phones in the classroom or at home; individually, in pair, or small groups; synchronously or asynchronously. While listening, the students take notes, and answer the questions. After listening, they discuss their answers. The instructor serves as a facilitator. She gives feedback, encouragement, and help with difficulties. Further recommendations for enhancing EFL college students’ listening skills and for extending the use of TTs to interpreting courses are given.

Differential Diagnostics Focal Pancreatics Masses Based on the Analysis of the Echographic Texture of Endosonograms Using Fuzzy Mathematical Models
Authors: Belozerov V. A. , Ohotnikov O. I. , Korenevskij N. A. , Grigorev S. N.
Published: October 2021

Relevance: Differential diagnosis of focal formations of the pancreas is particularly difficult due to the similarity of their echosemiotics. One of the ways to objectify and improve the accuracy of ultrasound data is to use artificial intelligence methods to interpret images.

Purpose: Improving the quality of diagnosis of focal pancreatic pathology according to endoscopic ultrasonography based on the analysis of the echographic texture using fuzzy mathematical models.

Material and methods: In the Kursk Regional Clinical Hospital, endoscopic ultrasonography was performed in 272 patients for pancreaticobiliary diseases. The endoscopic video system of the company Olympus EVIS EXERA II with the ultrasonic processor EU-ME1 was used. Solid tumors of the pancreas were detected in 109 (40.1 %) patients, focal pancreatic masses were diagnosed in 40 (14.7 %) patients. Based on the research results, the main types of reference endosonograms corresponding to differentiable pathology were identified. On the basis of endosonograms, using hybrid fuzzy mathematical decision rul, a fuzzy hybrid model of differential diagnosis of chronic focal pancreatitis and ductal adenocarcinoma of the pancreas was obtained.

Results: The selected source of information and the method of synthesis of hybrid fuzzy decision rules made it possible to obtain a fuzzy hybrid model of differential diagnosis of chronic focal pancreatitis and ductal adenocarcinoma of the pancreas. Based on the results of mathematical modeling and statistical tests on representative control samples, it was shown that the resulting model of differential diagnosis, using reference endosonograms reflecting the echographic texture of focal pancreatic masses, provides confidence in the desired diagnosis at the level of 0.6. The additional information used in the analysis of endosonograms increases the diagnostic confidence to a value of 0.9.

Conclusions: The resulting model of differential diagnosis of chronic focal pancreatitis and ductal adenocarcinoma of the pancreas provides confidence in decision-making no worse than 0.9, which is an acceptable quality indicator in clinical practice in conditions of insufficient statistics with poorly formalized data structure.

Relevance: Radionuclide bone scan signs of lesions are not specific and require radiological identification. Hybrid tomographic technology is a combination of spatial distribution of radiopharmaceuticals and its anatomical binding. Thus, makes it possible to accurately identify the affected bone structure and also determine the nature of this changes (radiological anatomy). In cancer patients, SPECT/CT method allows to visualize tumor pathology in the bones, but also keeps to a minimum errors and other excessive examinations.

Purpose: To demonstrate the most frequent diseases and conditions that simulate tumor lesions in bones on bone scan.

Material and methods: We analyzed the results of examinations of 81 patients with various tumor diseases (2015–2020). Bone scan was performed in the whole body 3 hours later, after intravenous administration of 99mTc-phosphotech on a Symbia E, T2 (Siemens, Germany). SPECT/CT was performed after WB Bone Scan.

Results: The most frequent reasons for the focal increased uptake of radiopharmaceutical were: reactive increase in metabolism and as a result additional mineral repair: deforming osteoarthritis, osteophytes; post‑traumatic and postoperative changes; fractures (osteoporosis and stress fractures); inflammatory processes; focal uptake due to the benign neoplasms of bones and dysplasia. Combination of highly sensitive but non-specific scintigraphy with highly specific computed tomography makes it especially useful in anatomically difficult areas.

Conclusion: SPECT/CT reveals a direct pater of anatomical and structural abnormalities with changes in bone tissue metabolism in case of different injuries and minimizes a number of ambiguous conclusions. SPECT/CT in oncological practice greatly helps nuclear medicine physician in the differential diagnostic process and reduces time of examination for the patient.

A method for simulation the effect of the reduced frequency resolution of the ear in patients with sensorineural hearing loss
Authors: Porhun M. I. , Vashkevich M. I.
Published: October 2021

A method for the simulation of reduced frequency resolution of the ear in patients with sensorineural hearing loss is proposed. The method is based upon the ability to adjust it according to the audiogram of a concrete person by frame-by-frame signal processing in the frequency domain. Simulation of the effect of the reduced frequency resolution of the ear is achieved by processing the components of amplitude spectrum of the original sound signal by the "smearing" function. The "smearing" function is formed from the amplitude-frequency characteristics of the auditory filters, which bandwidth is determined by the audiogram of the deaf person. The proposed method is implemented in the MATLAB. An experimental study of the effect of the reduced frequency resolution of the ear using the speech intelligibility test was conducted. The experiment involved 15 people who listened the records processed by the proposed method with various settings and noise conditions. Experimental data have shown that reduced frequency resolution of the ear leads to the deterioration in speech intelligibility, especially in the presence of background noise. Based on the answers of the participants of the experiment, the confusion tables of sounds were compiled, reflecting the fact of indistinguishability of sounds similar in frequency, that confirms the correctness of the proposed method.
Application of first-order logic to identify organizers and perpetrators of illegal actions in teams of a limited circle of people
Authors: Sobol A. М. , Kozlova E. I. , Chernyavsky Yu. A.
Published: October 2021

There are three main families of inference algorithms in first-order logic: direct inference and its application to deductive databases and production systems; backward inference procedures and logic programming systems; theorem proving systems based on the resolution method. When solving specific problems, the most effective algorithms are those that allow you to cover all the facts and axioms and must be taken into account in the process of inference. An example is considered in which it is necessary to prove the guilt of a person in murder. On the basis of statements, a knowledge base is formed from expressions, with the help of which an expression of first-order logic is compiled and proved using direct logical inference. The proof of the reasoning obtained in direct inference using the proof tree is given. However, direct inference provides for the implementation of all admissible stages of logical inference based on all known facts. The article also considers a method based on the resolution when implementing the reverse inference, taking into account the expression obtained in the direct inference. This expression is converted into a conjunctive normal formula using the laws of Boolean algebra and is proved by the elimination of events using the conjunction operation.
Sequential statistical decision making in problems of data flows analysis
Authors: Kharin A. Y.
Published: October 2021

In the problems of data flows analysis, the problems of statistical decision making on parameters of observed data flows are important. For their solution it is proposed to use sequential statistical decision rules. The rules are constructed for three models of observation flows: sequence of independent homogeneous observations; sequence of observations forming a time series with a trend; sequence of dependent observations forming a homogeneous Markov chain. For each case the situation is considered, where the model describes the observed stochastic data with a distortion. "Outliers" ("contamination") are used as the admissible distortions that adequately describe the majority of situations appear in practice. For such situations the families of sequential decision rules are proposed, and robust decision rules are constructed that allow to reduce influence of distortion to the efficiency characteristics. The results of computer experiments are given to illustrate the constructed decision rules.

Also, a search from gray literature (academic google, Open Gray) and references from the articles found in the first stage will be conducted.
BLOWING UP THE FASHION BUBBLE, OR NINE THINGS WRONG WITH FASHION: AN OUTSIDER’S COMMENT. A CRITICAL ESSAY ON FASHION AS A CREATIVE INDUSTRY
Authors: Stankevičiūtė Kristina
Published: October 2021

The world of fashion has lived in a bubble long before the concept found its way into social networks. Well before the social networks themselves, in fact. The very emergence of fashion as an idea occurred within the bubble of the social life at Palace of Versailles, France, where the notorious Louis XIV sported great interest in the looks of his court in addition to those of his own. The article is an outsider’s attempt to have a sober look at the fashion industry that until recently seemed to have maintained the “structure of feeling” of the 17th century Palace of Versailles. Today’s social realities, however, put fashion in the state of a shock that probably equals that of the Storming of the Bastille in 1789, even though it is presumably much less sudden. Written in the manner of the most popular contemporary fashion media format – a bullet list, the text presents a conceptual analysis of the world’s second most wasteful yet poisonously attractive industry, critically reflecting on such characteristic values of the fashion field as concept and features, hierarchy, arrogance, resources and philosophy.

At the end of 2020 November, two coronal mass ejections (CMEs) erupted from the Sun and propagated through the interplanetary medium in the direction of Parker Solar Probe while the spacecraft was located at ∼0.81 au. The passage of these interplanetary CMEs (ICMEs) starting on November 29 (DOY 334) produced the largest enhancement of energetic ions and electrons observed by the Integrated Science Investigation of the Sun (IS⊙IS) energetic particle instrument suite on board Parker Solar Probe during the mission’s first eight orbits. This was also the first spatially widespread solar energetic particle event observed in solar cycle 25. We investigate several key characteristics of the energetic electron event including the time profile and anisotropy distribution of near-relativistic electrons as measured by IS⊙IS’s low-energy Energetic Particle Instrument (EPI-Lo) and compare these observations with contextual data from the Parker Solar Probe Fields Experiment magnetometer. These are the first electron anisotropy measurements from IS⊙IS/EPI-Lo, demonstrating that the instrument can successfully produce these measurements. We find that the electron count rate peaks at the time of the shock driven by the faster of the two ICMEs, implying that the shock parameters of this ICME are conducive to the acceleration of electrons. Additionally, the angular distribution of the electrons during the passage of the magnetic clouds associated with the ICMEs shows significant anisotropy, with electrons moving primarily parallel and antiparallel to the local magnetic field as well as bidirectionally, providing an indication of the ICME’s magnetic topology and connectivity to the Sun or magnetic structures in the inner heliosphere.
Global Nature of Solar Coronal Shock Waves Shown by Inconsistency between EUV Waves and Type II Radio Bursts
Authors: Fulara Aarti , Kwon Ryun-Young
Published: October 2021

We re-examine the physical relationship between extreme ultraviolet (EUV) waves and type II radio bursts. It has been thought that they are two observational aspects of a single coronal shock wave. However, a lack of their speed correlation hampers the understanding of their respective (or common) natures in a single phenomenon. Knowing the uncertainties in identifying true wave components from observations and measuring their speeds, we re-examine the speeds of EUV waves reported in previous literature and compare these with type II radio bursts and coronal mass ejections (CMEs). This confirms the inconsistency between the speeds of EUV waves and their associated type II radio bursts. Second, CME speeds are found to have a better correlation with type II radio bursts than EUV waves. Finally, type II speeds and their range tend to be much greater than those of EUV waves. We demonstrate that the speed inconsistency is in fact an intrinsic tendency and elucidate the nature of a coronal shock wave consisting of both driven and non-driven parts. This suggests that the speed inconsistency would remain even if all other uncertainties were removed.

Metal-rich near-Earth asteroids (NEAs) represent a small fraction of the NEA population that is mostly dominated by S- and C-type asteroids. Because of this, their identification and study provide us with a unique opportunity to learn more about the formation and evolution of this particular type of bodies, as well as their relationship with meteorites found on Earth. We present near-infrared (NIR) spectroscopic data of NEAs 6178 (1986 DA) and 2016 ED85. We found that the spectral characteristics of these objects are consistent with those of metal-rich asteroids, showing red slopes, convex shapes, and a weak pyroxene absorption band at ∼0.93 μm. The compositional analysis showed that they have a pyroxene chemistry of Fs40.6±3.3Wo8.9±1.1 and a mineral abundance of ∼15% pyroxene and 85% metal. We determined that these objects were likely transported to the near-Earth space via the 5:2 mean motion resonance with Jupiter. Asteroid spectra were compared with the spectra of mesosiderites and bencubbinites. Differences in the NIR spectra and pyroxene chemistry suggest that bencubbinites are not good meteorite analogs. Mesosiderites were found to have a similar pyroxene chemistry and produced a good spectral match when metal was added to the silicate component. We estimated that the amounts of Fe, Ni, Co, and the platinum group metals present in 1986 DA could exceed the reserves worldwide.
Extinct before discovered? Epactoides giganteus sp. nov. (Coleoptera, Scarabaeidae, Scarabaeinae), the first native dung beetle to Réunion island

We describe a new species of dung beetle,Epactoides giganteussp. nov., from a single female specimen allegedly collected in the 19thcentury on Réunion island and recently found at the Muséum national d’Histoire naturelle, Paris. This species differs from other species ofEpactoidesby larger size and a set of other distinctive morphological characters.Epactoides giganteussp. nov.is the first native dung beetle (Scarabaeinae) of Réunion, and its discovery expands the known area of distribution of the genusEpactoides, which was hitherto believed to be endemic to Madagascar. Like other taxa from Madagascar and peripheral islands (e.g., Comoro, Seychelles, Mascarenes),E. giganteussp. nov.may have reached Réunion by over-water dispersal. Given the rapid loss of biodiversity on Réunion island and the fact that no additional specimens were re-collected over the last two centuries, it is very likely thatE. giganteussp. nov.has gone extinct. However, we have unconfirmed evidence that the holotype ofE. giganteussp. nov.might be a mislabeled specimen from Madagascar, which would refute the presence of native dung beetles on Réunion. We discuss both hypotheses about the specimen origin and assess the systematic position ofE. giganteussp. nov.by examining most of the described species of MadagascanEpactoides. Additionally, we provide a brief overview of the dung beetle fauna of Mascarene Archipelago.

Objective

To determine the indication and risk of 30-day rehospitalization after hip or knee replacement among patients with rheumatoid arthritis (RA) and osteoarthritis (OA) by Medicare and non-Medicare status.

Methods

Using the Nationwide Readmission Database (2010–2014), we defined an index hospitalization as an elective hospitalization with a principal procedure of total hip (THR) or knee replacement (TKR) among adults aged ≥ 18 years. Primary payer was categorized as Medicare or non-Medicare. Survey logistic regression provided the odds of 30-day rehospitalization in RA relative to OA. We calculated the rates for principal diagnoses leading to rehospitalization.

Results

Overall, 3.53% of 2,190,745 index hospitalization had a 30-day rehospitalization. Patients with RA had a higher adjusted risk of rehospitalization after TKR (OR 1.11, 95% CI 1.02–1.21) and THR (OR 1.39, 95% CI 1.19–1.62). Persons with RA and OA did not differ with respect to rates of infections, cardiac events, or postoperative complications leading to the rehospitalization. After TKR, RA patients with Medicare had a lower venous thromboembolism (VTE) risk (OR 0.58, 95% CI 0.58–0.88), whereas those with RA had a greater VTE risk (OR 2.41, 95% CI 1.04–5.57) after THR.

Conclusion

Patients with RA had a higher 30-day rehospitalization risk than OA after TKR and THR regardless of payer type. While infections, postoperative complications, and cardiac events did not differ, there was a significant difference in VTE as the principal diagnosis of rehospitalization.

Objective

We examined the association between schizophrenia genetic susceptibility loci and neuropsychiatric systemic lupus erythematosus (NPSLE) features in childhood-onset SLE (cSLE) participants.

Methods

Study participants from the Lupus Clinic at the Hospital for Sick Children, Toronto, met ≥ 4 of the American College of Rheumatology and/or SLE International Collaborating Clinics SLE classification criteria and were genotyped using the Illumina Multi-Ethnic Global Array or the Global Screening Array. Ungenotyped single-nucleotide polymorphisms (SNPs) were imputed, and ancestry was genetically inferred. We calculated 2 additive schizophrenia-weighted polygenic risk scores (PRS) using (1) genome-wide significant SNPs (P < 5 × 10–8), and (2) an expanded list of SNPs with significance at P < 0.05. We defined 2 outcomes compared to absence of NPSLE features: (1) any NPSLE feature, and (2) subtypes of NPSLE features (psychosis and nonpsychosis NPSLE). We completed logistic and multinomial regressions, first adjusted for inferred ancestry only and then added for variables significantly associated with NPSLE in our cohort (P < 0.05).

Results

We included 513 participants with cSLE. Median age at diagnosis was 13.8 years (IQR 11.2–15.6), 83% were female, and 31% were of European ancestry. An increasing schizophrenia genome-wide association PRS was not associated with NPSLE (OR 1.04, 95% CI 0.87–1.26, P = 0.62), nor with the NPSLE subtypes, psychosis (OR 0.97, 95% CI 0.73–1.29, P = 0.84) and other nonpsychosis NPSLE (OR 1.08, 95% CI 0.88–1.34, P = 0.45), in ancestry-adjusted models. Results were similar for the model including covariates (ancestry, malar rash, oral/nasal ulcers, arthritis, lymphopenia, Coombs-positive hemolytic anemia, lupus anticoagulant, and anticardiolipin antibodies) and for the expanded PRS estimates.

Conclusion

We did not observe an association between known risk loci for schizophrenia and NPSLE in a multiethnic cSLE cohort. This work warrants further validation.

L’exiguïté de l’espace et les ressources limités, la relation spécifique avec la mer, les frontières bien définies, l’endémisme et la particularité sociale sont quelques-unes des caractéristiques associées aux îles. Cependant, dans l’univers insulaire, il existe de nombreuses situations et l'utilisation de chorotypes, c'est-à-dire de formes spatiales complexes et répétitives formées d'une composition de chorèmes, permet d’explorer certaines des possibilités de l'insularité. À cette fin, nous avons eu recours à des exemples d’îles et d’archipels du Brésil et du monde entier.
IGEPAC-Bela Vista e o tombamento do Teatro Oficina: Representação, governo e contestação no Bixiga
Authors: Cadena Dirceu
Published: October 2021

O objetivo deste trabalho é discutir a produção da representação do Bixiga no Inventário Geral do Patrimônio Ambiental, Cultural e Urbano de São Paulo-Bela Vista (IGEPAC-Bela Vista). Considera-se que a geografia política contemporânea pode ser analisada a partir de representações, decisões governamentais e movimentos de contestação, aspectos analisados no Bixiga no quadro da política patrimonial. A análise dos documentos produzidos para exigir o tombamento do Teatro Oficina ou o pedido de criação de um parque público no terreno adjacente ao edifício mostrará que o grupo associado ao teatro mobilizou diversas legislações patrimoniais para contestar as decisões governamentais e construir novas representações para o bairro.

Neste artigo buscamos apresentar que os(as) gays, apesar de historicamente invisibilizados, patologizados e/ou criminalizados, se constituem de agentes importantes na produção do espaço geográfico. Após uma breve historicidade sobre a questão homossexual no Ocidente e o estado da arte da discussão desta temática na Geografia, buscamos sintetizar os dados disponíveis sobre esta população no Brasil na saúde e na demografia. A partir de mapas, discutimos como o fato urbano-metropolitano é importante para a compreensão da realidade gay do Rio Grande do Sul e provocamos sobre a necessidade de trazer à tona, na Geografia, o debate sobre as LGBT, removendo estes grupos da invisibilidade e de forjar novas interpretações sobre produção do espaço e da dinâmica urbana-metropolitana, exaltando a necessidade de ampliar a coleta de dados nos sistemas de informação existentes.

Este trabalho objetiva demonstrar os resultados da espacialização das concentrações hidrogeoquimicas na água subterrânea da 17ª Regional de Saúde de Londrina-PR obtidas a partir da amostragem em campo e análise química instrumental por meio de Espectometria de Emissão Atômica (ICP-AES). Esta espacialização visa evidenciar áreas que possam sugerir um cuidado maior por parte das autoridades publicas com vistas a evitar possíveis agravos à saúde da coletividade decorrentes do consumo da água subterrânea com teores anormais de substâncias químicas tais como o Bário (Ba), Cálcio (Ca), Cromo (Cr), Ferro (Fe), Magnésio (Mn) e Silício (Si). A partir das ocorrências encontradas, verificou-se que algumas porções do território apresentam anomalias geoquímicas que suscitam cuidado por parte dos governos locais visto que concentrações anômalas destes elementos podem promover agravos à saúde coletiva regional.
