Authors: Лутков С.А. , Тезиков А.В.
Published: July 2021

Работа посвящена изучению влияния формы отражающей поверхности на результаты картографирования дна и съемки подводных объектов гидроакустическими средствами. Проведена сравнительная оценка качества картирования дна однолучевыми эхолотами и многолучевыми эхолотами. Опыт применения гидроакустических средств измерения глубины показывает, что в районах с выровненным рельефом глубины, измеряемые однолучевыми эхолотами, многолучевыми эхолотами, интерферометрическими эхолотами и механическими лотами, совпадают. В районах со сложным рельефом глубины, измеренные однолучевыми эхолотами, превышают глубины, измеренные многолучевыми эхолотами, и сильно варьируются. Разработана математическая модель для исследования искажений отображения гидролокатора донной поверхности в зависимости от кривизны отражающей поверхности. Получены аналитические зависимости, позволяющие восстановить форму отражающей поверхности по результатам гидроакустических измерений.

The work is devoted to the study of the influence of the shape of the reflecting surface on the results of bottom mapping and underwater objects survey using hydro acoustic means. A comparative assessment of the quality of bottom mapping performed by single-beam echo sounders and multi-beam echo sounders was performed. The experience of using hydro acoustic depth measurement tools shows that in areas with leveled terrain, the depths measured by single-beam echo sounders, multi-beam echo sounders, interferometric echo sounders and mechanical lots coincide. In areas with complex terrain, the depths measured by single-beam echo sounders exceed the depths measured by multi-beam echo sounders, and vary greatly. A mathematical model is developed for studying the distortions of the bottom surface sonar display depending on the curvature of the reflecting surface. Analytical dependences are obtained that allow us to restore the shape of the reflecting surface based on the results of sonar measurements.

В статье рассматривается процесс предварительной прокладки судна. Показаны подходы к процессу, а также современное состояние дел. В результате делается промежуточный вывод о том, что современная система коридоров безопасности может быть не совсем адекватна в реальных условиях использования с системами искусственного интеллекта. Сделана классическая постановка задачи выбора элементов планирования пути. Были рассмотрены факторы, влияющие на безопасность, и поставлены 2 задачи. Первая связана с подбором элементов и оценкой их отдельного влияния на риски и безопасность. Выведены две формулы, позволяющие оценить коэффициенты, характеризующие точку поля, где идёт судно. В рамках второй задачи рассчитаны примерные графики величин. График рисков из-за близости к опасности был построен разложением на соотвествующие дискреты. При этом, график целесообразности нахождения в пространстве был сделан для плеча в 10 миль с максимальным отклонением в полмили. Показан совершенно разный темп падения/роста параметров. Как следствие, показана их сочетаемость.

The article deals with the process of preliminary plotting of a vessel's route. Approaches to the process are shown, as well as the current state of Affairs. As a result, an intermediate conclusion is made that the modern system of security corridors may not be quite adequate in real conditions of use with artificial intelligence systems. The classical formulation of the problem of selecting elements of path planning is made. Factors affecting safety were considered and 2 tasks were set. The first is related to the selection of elements and the assessment of their individual impact on risks and security. Two formulas are derived that allow us to estimate the coefficients that characterize the point of the field where the ship is going. In the second task, approximate graphs of values are calculated. The risk graph due to proximity to the hazard was constructed by decomposing it into the appropriate discrete values. At the same time, the graph of the expediency of being in space was made for a leg of 10 miles with a maximum deviation of half a mile. A completely different rate of decline/growth of parameters is shown. As a result, their compatibility is shown.

Authors: Khaeva O. E. , Ikoeva L. P.
Published: July 2021

In conditions of multiple drug resistance of microorganisms to recently used drugs, the search for new chemotherapeutic agents with a pronounced bactericidal or bacteriostatic effect with low toxicity and teratogenicity remains relevant. Chromone derivatives with a wide spectrum of pharmacological activity (membrane-stabilizing, antiviral, antibacterial, anti-inflammatory, cardioprotective, antioxidant) are promising compounds for the search for new generation chemotherapeutic drugs.
As a result of the study, it was found that gram-positive bacteria Staphylococcus aureus shows the highest sensitivity to the studied compounds when growing on a liquid nutrient medium. The studied compounds are also active against pathogenic strains of Bacillus cereus, Escherichia coli. The minimum inhibitory concentration (IPC) of the most active substances in relation to St. strains aureus is 10 μg/ml for 7-acetoxy-3-(p-bromophenyl)iminomethylchromone, and for 3-(p-bromophenyl)-iminomethylchromone and 7-acetoxy-3-(p-sulfamidophenyl)iminomethylchromone – 20 μg/ml. For 7-acetoxy-3- (p-bromophenyl)iminomethylchromone and 3-(p-bromophenyl)iminomethylchromone, a high antibacterial activity was revealed with respect to the spore-forming bacteria Bacillus subtilis – MPC – 20 μg / ml. The synthesized compounds exhibit a low bacteriostatic activity with respect to the Pseudomonas aeruginosa strain.
Experimental studies have shown that the nature and position of substituents in the structure of 3–aryliminomethylchromones affects their antibacterial activity against strains of gram-positive bacteria Staphulococcus aureus and Bacillus subtilis, a strain of gram-negative bacteria: Escherichia coli. The presence in the series of synthesized 3–aryliminomethylchromones of compounds with high bacteriostatic activity at the level of an antibacterial drug from the group of sulfonamides – norsulfazole was established.

The study is devoted to ontomorphogenesis and the structure of cоenopopulations of the rare species Crepis purpurea (Willd.) M. Bieb., protected by the Red Data Book of Sevastopol, the Republic of Crimea, Turkey and I Appendix of the Berne Convention.
The duration, morphological and anatomical features of the age states in the pregenerative, generative and senile periods of C. purpurea ontogenesis are established. The total duration of ontogenesis is 5–6 years, which includes 4 ontogenetic periods and 9 age states. C. purpurea is characterized by the structural type of polyvariance with the formation of 3 ontobiomorphic variants: individuals with one-, two-, or many-headed caudex. The features and the period of the onset of anatomical partition in the shoot part caudex were revealed. Germination of C. purpurea seeds was determined.
The ontogenetic, vitality and spatial structure of 11 Crimean cоenopopulations of C. purpurea were carried out. The lack of the pregenerative and senile individuals fractions is observed in coenopopulations. The basic ontogenetic spectrum of the studied populations is bimodal with a peak on virgin and mature generative individuals. The indices of renewability, generativeness, aging, the general age of the population, as well as the age indices of A. A. Uranov and the efficiency of L. A. Zhivotovsky were calculated for each population. In the vital structures there is a dynamic on the increase in the values of the index of vital quality of populations from the eastern foothills to the western foothills and further – to the mountain plateaus variants of populations. It was established that individuals of C. purpurea have a tendency to tend to a group type of distribution in the population. The data on areas of coenopopulations, the number and density of individuals of C. purpurea in the studied communities are presented.

Published: July 2021

Stem Bark, Root and fruit of Ziziphus oenoplia (Rhamnaceae) has been used in traditional health systems to treat diabetes and many more disorders in southern Asia as India, Sri Lanka and Burma. However hypoglycemic and hypo-lipidemic potential of fruit of this valuable plant is not scientiﬁcally validated till date. The aim of present study is to evaluate hypoglycemic and hypo-lipidemic effect of ethanol extracts and solvent fractions of Ziziphus oenoplia fruit. The ethanol extracts and solvent fractions in different dose concentration 100, 200, 400 mg/kg of Ziziphus oenoplia fruit were evaluated for hypo-glycemic effect in single dose and multiple dose study for 21 days as well as for hypo-lipidemic potential in streptozotocin induced diabetic rats. The outcome of present study indicates, crude extract and solvent fractions significantly reduce blood glucose level on normoglycemic and diabetic rats.The acute oral toxicity study of Z. oenoplia fruit extract did not show mortality in the animals at the limit dose of 2g/kg. In STZ induced diabetic rat, maximum BGL lowering effect produced by EEZO400 followed by CF400 after 21 days of treatment. Total cholesterol, triglycerides and low-density lipoprotein was also significantly decreased. The observed result may be due to active principles present in extract and fractions. The result showed the potential effects of Z.oenoplia fruit extract and fractions as hypoglycemic and anti hyper-lipidemic in dose dependant manner compare to glibenclemide as standard drug. The claimed traditional use as anti-diabetic has scientiﬁc back ground.

Published: July 2021

Aim:
Although clinicians primarily diagnose dementia based on a combination of metrics such as medical history and formal neuropsychological tests, recent work using linguistic analysis of narrative speech to identify dementia has shown promising results. We aim to build upon research by Thomas JA & Burkardt HA et al. (J Alzheimers Dis. 2020;76:905–2) and Alhanai et al. (arXiv:1710.07551v1. 2020) on the Framingham Heart Study (FHS) Cognitive Aging Cohort by 1) demonstrating the predictive capability of linguistic analysis in differentiating cognitively normal from cognitively impaired participants and 2) comparing the performance of the original linguistic features with the performance of expanded features.
Methods:
Data were derived from a subset of the FHS Cognitive Aging Cohort. We analyzed a sub-selection of 98 participants, which provided 127 unique audio files and clinical observations (n = 127, female = 47%, cognitively impaired = 43%). We built on previous work which extracted original linguistic features from transcribed audio files by extracting expanded features. We used both feature sets to train logistic regression classifiers to distinguish cognitively normal from cognitively impaired participants and compared the predictive power of the original and expanded linguistic feature sets, and participants’ Mini-Mental State Examination (MMSE) scores.
Results:
Based on the area under the receiver-operator characteristic curve (AUC) of the models, both the original (AUC = 0.882) and expanded (AUC = 0.883) feature sets outperformed MMSE (AUC = 0.870) in classifying cognitively impaired and cognitively normal participants. Although the original and expanded feature sets had similar AUC, the expanded feature set showed better positive and negative predictive value [expanded: positive predictive value (PPV) = 0.738, negative predictive value (NPV) = 0.889; original: PPV = 0.701, NPV = 0.869].
Conclusions:
Linguistic analysis has been shown to be a potentially powerful tool for clinical use in classifying cognitive impairment. This study expands the work of several others, but further studies into the plausibility of speech analysis in clinical use are vital to ensure the validity of speech analysis for clinical classification of cognitive impairment.

Published: July 2021

Aim: Impaired sleep quality and sleep oxygenation are common sleep pathologies. This study assessed the impact of these abnormalities on white matter (WM) integrity in an epidemiological cohort. Methods: The target population was the Framingham Heart Study Generation-2/Omni-1 Cohorts. Magnetic resonance imaging (diffusion tensor imaging) was used to assess WM integrity. Wearable digital devices were used to assess sleep quality: the (M1-SleepImageTM system) and the Nonin WristOx for nocturnal oxygenation. The M1 device collects trunk actigraphy and the electrocardiogram (ECG); sleep stability indices were computed using cardiopulmonary coupling using the ECG. Two nights of recording were averaged. Results: Stable sleep was positively associated with WM health. Actigraphic periods of wake during the sleep period were associated with increased mean diffusivity. One marker of sleep fragmentation which covaries with respiratory chemoreflex activation was associated with reduced fractional anisotropy and increased mean diffusivity. Both oxygen desaturation index and oxygen saturation time under 90% were associated with pathological directions of diffusion tensor imaging signals. Gender differences were noted across most variables, with female sex showing the larger and significant impact. Conclusions: Sleep quality assessed by a novel digital analysis and sleep hypoxia was associated with WM injury, especially in women.

The paper reviews the topicality and practical significance of the implementation of processing technology of plastic with the purpose of obtaining raw material for manufacturing motor benzene. It is shown that this case is the advantageous strategy for the damage reduction to the environment from the oil-gas complex and usage of commercial gasoline based on the fossil hydrocarbon crude and for the utilization of plastic wastes as well. The perspective technologies of plastic processing including pyrolysis, catalytic cracking, hydrothermal liquefaction based on the bibliographic review and the recommendations on the improvement of benzene component obtained as a basis for industrial production of motor benzene are presented. In the capacity of the last ones, the implementation of alcohol mixed octane-increasing additives based on the ethanol is justified. It is shown that using alcohol not only increases octane number of the fuel, but also saves expensive hydrocarbon components, allows reducing the toxic high-octane aromatic hydrocarbons in the gasoline, improves the distribution of octane numbers by benzene fractions based on the reformat, as well as expands the crude base for fuel production due to the non-oil raw. The studies showed that adding 10 % of alcohol is the optimum concentration, as on the one hand it provides the growth of knock characteristics and phase stability of the gasoline, on the other hand does not require additional regulation of motor engine for using such fuel.

The hydrodynamic flow of gas-liquid mixture was investigated in the vertical pipeline. It is confirmed by the existing experiment in technical references that to obtain theoretical work, taking into account B.A. Arkhangelsky`s theoretical basis dependence γfix/γl of friction is necessary. A new pressure gradient model tested in a great number of wells was chosen as well. Pressure losses for liquid and gas mediums are calculated by the Blazius formula, where the components in the mixture move in turbulent regime. The accuracy of the dependencies was verified using A.P Krylov`s experimental dependencies. A calculation method differ from A.P. Krylov`s has been developed. Via proposed method it was defined that each regime has its specific pressure gradient and there cannot be constant gradient for various regimes as A.P. Krylov shows.

Authors:   Azerbaijan State University of Oil and Industry, Zeynalova G.A.
Published: July 2021

The analysis justifies that the hydraulic properties of pipelines collecting and transporting difficult-to-decompose oil emulsions should be taken into account for their calculation and increasing operational efficiency of the pipelines. The structural sustainability of water-oil emulsions in various temperatures and watercut degrees of oils in technological pipelines based on the study of abnormal rheological properties have been analyzed. It was defined that these systems with relaxation behavior as well in the motion through the pipelines may lose the structural stability. It was revealed that the transition to the turbulent mode of oil emulsions with various watercut degrees takes place in the generalized Reynolds number Re * = 1200.

Published: July 2021

Allah Al-Mighty send the human beings in this universe with a complete code of guidance in the form of the Qur’┐n and Sunnah of the Prophet (╗AWS). Both these sources guide different fields of life principally. The commandments of the Qur’┐n and Sunnah are unchangeable. No one can ignore them, but the problems of life are endless. And solution of all these problems cannot be presented in a single book. So, the Shar┘‘ah has introduced the principle of ijtih┐d to resolve all these issues.  Ijtih┐d is not to create something new in religion rather it is to tell the point of view of religion about the newly born problems. But it should also be kept in mind that to perform Ijtih┐d there are certain terms and conditions, which if not fulfilled will spoil the concept of ijtih┐d. These terms and conditions have been discussed and modified time to time. The former Scholars of Isl┐m have a detailed discussion on this topic. The Scholars of present era also have focused this topic and have presented its requirements in the current era but in this paper, the opinions of former scholars are going to be discussed in detail. The opinions of the scholars of present era will be presented in the other paper.

This study aims to assess the Hadith: “There is hesitation in everything except in the actions of the next world.” After picking the said Hadith from its original source, its isnaad and graded along with its transmission. The fundamental contemporary challenge is the eagerness for matters of this life and disregard of matters of the Afterlife. This hadith teaches us that happiness and success are contrary to such an approach. Rather, happiness can only occur with hesitation towards matters of this life and ambition and hastiness towards matters of the Afterlife.
Al-Ghazali And Hume On Natural Causal Necessity And Miracles
Authors: Syed Jawad Ali Shah  , Ahmad Shuja
Published: July 2021

This paper argues that Al-Ghazali and Hume arrived at same conclusion i.e.both reject natural causality as a logical necessity however they provide very different premises for this conclusion. Moreover, Hume’s rejection of the natural causal necessity leads him to religious skepticism whereas, Al-Ghazali’s rejection of natural causal necessity leads him to have a strong faith in God and Miracles. The paper discusses the problem of causation in their philosophies focusing on the issues such as: causation as habit; uniformity in the natural order; causation is a mere sequence of observed things; whether causal relation is ontological or epistemological; issues related to miracles and diverse possibilities. Furthermore, the paper also focuses on the issue of Occasionalism and free will with special reference to Al-Ghazali and Hume.

Published: July 2021

In the proliferation and spread of Islam, the part of the financial manager and busninessmen has stayed extremely huge. The Holy Prophet (PBUH) was a celebrated and legit Arab busninessman, and his high-height colleagues were considered among the conspicuous and effective Arab financial specialists. Numerous sacred rewards have been said in support of authentic and genuine trade in the Holy Prophet's sayings (conventions). Today the manipulation of consumers through advertisement has also become a routine practice. Therefore, it is essential for the businessmen while advertising to maintain the rules and principles set for it by Shariāh  to promote their business and fulfil the rights of the consumers. Advertising of items and services, in itself is not prohibited in Islam because its purpose is to keep the masses aware and to provide them with related information. This paper aims to study the ethics of business from the practical aspect of Prophet’s life (PBUH).

Polyparadigmality of modern Kazakhstan education in the formation of a competent teacher
Authors:   Kyrgyz Academy of Education, Dobaev K. , Sergeeva V. ,   Innovative University of Eurasia, Ramazanova N. ,   Innovative University of Eurasia
Published: July 2021

In recent years, several trends can be recorded in the educational space. There is a great variety, including the emergence of new competing educational theories and practices that represent different educational paradigms. This situation makes it relevant to address the issue of the nature of the existence of educational paradigms and their role in the formation of future teachers ' competencies, including social and personal ones. The purpose is to analyze the polyparadigmality of modern Kazakh education and its role in the formation of the teacher's social and personal competence. We used methods of analysis, synthesis and deduction. The analysis of the competence approach is based on the descriptive-analytical method. Polyparadigmality in the field of education is analyzed as a natural phenomenon. The methodological basis for the analysis of various positions of researchers and teachers was the general scientific definition of the paradigm given by T. Kuhn. According to him, it is a set of theoretical and methodological attitudes, a concept more general than a theory, concept or approach. Several pedagogical theories, concepts, or approaches may correspond to the same paradigm that serves as their ideological basis. Returning to the general scientific interpretation of the paradigm will eliminate confusion in understanding the accumulated experience and prospects of education, and will help to adequately perceive the pedagogical reality in the formation of competencies. The expansion and development of knowledge in the field of formation of teachers' competencies is inevitable, so a change in the pedagogical paradigm is inevitable and necessary. The synthesizing core in it should be a culture that combines science, art and spiritual teachings into the integrity of the noosphere. Today, in pedagogy, much attention is paid to the combination and complementarity of pedagogical paradigms. Competent perception of the polyparadigmality of education by both teachers and students, as well as awareness of the complex nature of the polyparadigm approach in the education of the future teacher, in our opinion, will provide a qualitative level of formation of a competent teacher at the stage of their training at the university. Most modern scientists (S. V. Belova, O. S. Gazman, I. G. Fomicheva, etc.) admit the simultaneous existence of several paradigms in the same conditions of education, possibly with the dominant role of one of them at a particular stage. Thus, as the main strategy for the formation of the teacher's social and personal competence, we assume the harmonization of various educational paradigms.

In the conditions of modern economy, factors that affect the security of the business, but relate to external resources in relation to the company or opportunities, become significant. These resources and opportunities in economics have traditionally been identified with macro-economic (economic growth, inflation, exchange rates, government support) and institutional parameters (regulatory framework, transaction costs). The influence of the quality of economic space on economic security of business through the evaluation of opportunities that are tied to the specifics of the economic space is the least researched, including in our country. In this case, according to the latest research in the field of economic geography, economic space acts as a structure-forming platform that can form local markets, with intensive interaction of business agents. The purpose of this study is ensuring of economic security by building business networks in a single economic space. The research area focuses on indicators that characterize economic space, which are successfully used in international practice to determine the quality of economic space. The realization of this approach requires the use of traditional methods of scientific research, such as analysis, comparison, graphical method for visualizing obtained results, which allows determining the agglomeration zone and the space of business networks in it. When considering economic space in relation to building a business network in improving business security, main focus is on the quality of economic space that the region has. The proposed methods of evaluating the quality of economic space are actively used to determine the possibility of building business networks in this space. The authors conclude that business networks play a crucial role in improving the economic security of business in a particular economic space. The set of proposed measures provides additional opportunities and increases the influence of economic space on business security and creates the zone of maximum external security.

The sharp deterioration of the environmental situation in the Republic of Kazakhstan, associated with human activity and the impact of harmful factors on the environment, affected the quality of food consumed by insufficient consumption of domestic fruit and vegetable products containing vitamins, minerals of an alkaline nature, carbohydrates, vegetable proteins, pectin substances and active fiber. The problem of improving the quality of growing and processing fruits and vegetables is one of the main tasks of the food independence of the Republic of Kazakhstan. Currently, the share of large vegetable farms in the Republic of Kazakhstan is only 10%. The volume of industrial processing of fruit and vegetable crops in Kazakhstan is insignificant. The demand for domestic fruit and vegetable products in the country is met only by 35-40%, most of it is imported from countries such as Russia, Kyrgyzstan, Uzbekistan and China. There is a need for the development of organic vegetable growing in Kazakhstan and the creation of new types of domestic fruit and vegetable products containing a sufficient amount of useful and active substances that can bind and remove toxic substances and radioactive elements from the human body. The purpose of the work is to improve the technology of fruit and vegetable semi-finished products with natural spicy and aromatic additives, to develop a multi-component recipe for vegetable mixtures and a method for producing quick-frozen vegetable mixtures with high quality indicators. These studies were aimed at studying the chemical composition and functional and technological properties of vegetables and spicy - aromatic plants for the content of biogenic compounds: carbohydrates, proteins, vitamins, essential oils, minerals and other substances. The structure of plant tissues was studied and the mass fraction of moisture, dry matter, fiber, mono - and disaccharides, pectin substances, vitamin C was determined, the formulation and production technology of Assorted vegetable mixtures were developed, and quality indicators were determined.

Published: July 2021

El cantón Rocafuerte, fundado en el año1852, es una localidad ubicada en la zona central oeste de la provincia de Manabí. Su principal actividad económica se desarrolla en los ámbitos de la agricultura, ganadería y producción artesanal de dulces, que tienen mucha acogida a nivel nacional e internacional. Uno de los principales problemas de la zona que inciden en su normalidad es el déficit de agua durante los periodos de estiaje, que se presenta, por lo general, entre los meses de junio y noviembre de cada año. Este artículo realiza una valoración del recurso hídrico que se genera en la cuenca donde está asentado el cantón Rocafuerte; esta valoración constituye una información básica para el control, optimización de obras y proyectos tendentes al manejo y uso de dicho recurso. Para el análisis se utilizaron métodos estadísticos y probabilísticos sobre los registros de precipitaciones mensuales que genera el Instituto Nacional de Meteorología e Hidrología del Ecuador (INAMHI). Entre estos métodos se destacan el registro de datos mediante el método de correlación ortogonal; el análisis de consistencia y de variabilidad; la estimación de la precipitación media multianual; la aplicación del método del Servicio de Conservación de Suelos de los E.E.U.U. (SCS) para el cálculo de la escorrentía y la distribución media mensual multianual de la precipitación. Las estaciones meteorológicas, que se consideraron dentro del área de estudio, fueron 4: Estación Rocafuerte (M165), Portoviejo (M005), Río Chico (M454) y Junín (M462).

Published: July 2021

El objetivo de esta investigación fue concebir un cuerpo teórico y práctico para resemantizar el modelo de mantenimiento centrado en confiabilidad para su aplicación en plataformas de telecomunicaciones y transmisión de datos, lo que permite un nuevo enfoque metodológico para la gestión del mantenimiento en este tipo de infraestructura. Se trata de una propuesta innovadora en dos grandes aspectos: en primer lugar, en lo relativo a la adaptación del modelo de mantenimiento generado y su aplicabilidad en cualquier entorno tecnológico de telecomunicaciones y transmisión de datos, y, en segundo lugar, respecto de la manera en que esta propuesta se reinterpreta mediante un marco conceptual particular ampliamente probado para su aplicación inédita en otros contextos tecno-productivos. En cuanto al diseño operativo, se desarrolló una integración de la Metodología de Mantenimiento Centrado en Confiabilidad (MCC) y el Control Objetives for Information and Related Technology (COBIT). Como principal producto se generó un programa de mantenimiento con base en un nuevo esquema operativo denominado Metodología de Mantenimiento Confiable para Plataformas de Telecomunicaciones (MCPT), lo que constituye una herramienta innovadora para la prevención y el control de fallos en procesos de mantenimiento.
Trasmisión de volatilidad del covid-19 a los precios de acciones del sector bancario e industrial de Sudamérica, México y Estados Unidos
Authors: Peñafiel Chang Luis Eduardo
Published: July 2021

Este trabajo tiene como objetivo la modelización de la volatilidad de los precios de acciones del sector bancario e industrial de Sudamérica, México y Estados Unidos en el contexto de la pandemia del COVID-19. Para ello, se estiman los modelos TGARCH (1,1) y EGARCH (1,1). Estos modelos empíricos son ventajosos, porque permiten una respuesta asimétrica de la varianza condicionada en función del signo de los residuos. Es un elemento crucial para los diseños de cartera y gestión de riesgos, y la medición de la volatilidad de los mercados financieros para capturar potenciales oportunidades o pérdidas de inversión. El análisis realizado revela que Brasil fue el más volátil ante el impacto del COVID-19; lo siguen Colombia, Perú, Chile y Argentina. Un caso aparte son Ecuador y México que no tuvieron impacto significativo en la volatilidad de los precios de las acciones. Por otro lado, el shock del COVID-19 ha impactado en mayor medida a la volatilidad del sector industrial en Sudamérica y México, mientras que al bancario en los Estados Unidos.

As empresas buscam incessantemente por eficiência nas suas atividades e também na forma de dividir os seus custos para realização, procurando cada vez mais, por meio de uma otimização de seus processos, reduzir os custos e despesas aumentando seus resultados. Neste sentido, a instituição financeira estudada criou uma retaguarda centralizada de processos, que tem o nome de Back Office. Este realiza atividades operacionais de forma centralizadas em um único local, com isso retirou das Unidades de Atendimento a parte operacional, deixando-a com mais oportunidade de realizar novos negócios, atender melhor ao seu associado, aprimorar o relacionamento, a satisfação do mesmo com a instituição e com os negócios realizados. O trabalho tem o objetivo de apresentar uma proposta de rateio dos serviços prestados, isto para que de uma forma mais assertiva sejam identificados os custos de cada processo feito, e com base nos custos sejam elaborados os rateios por quantidade de serviços prestados versus custos. O maior desafio é elaborar um critério de rateio de custos envolvidos em cada serviço realizado no Back Office. A base conceitual utilizada é o custeio ABC e a metodologia abrange uma pesquisa aplicada, descritiva com coleta de dados por meio de entrevistas despadronizadas. O resultado do estudo apresenta uma proposta de rateio de custos, é feita com base em um percentual de complexidade que é dado para cada atividade e, desta forma, cada Unidade de Atendimento saberá o custo de cada serviço contratado resultando na eficiência de gerenciamento de custos e processos.
Narrativas sobre a Síndrome Pós-pólio em associações de pacientes do Brasil e da Espanha nos meios digitais
Authors: Souza Fialho da Silva Danielle
Published: July 2021

A Síndrome Pós-poliomielite (SPP) é uma patologia que afeta pessoas que tiveram pólio muitos anos depois da doença aguda. É considerada uma doença crônica e rara e seus sintomas caracterizam-se por fraqueza muscular, fadiga intensa e dores musculares e articulares, entre outros sintomas. O objetivo deste artigo é compreender que narrativas sobre a doença são divulgadas pelas associações de pacientes com Síndrome Pós-pólio e seus usos nos meios digitais. Analisaremos duas organizações de pacientes, uma do Brasil e uma da Espanha, a saber: a Associação Brasileira de Síndrome Pós-poliomielite (Abraspp), fundada em 2004 em São Paulo, Brasil, e a Asociación Afectados de Polio y Síndrome Post-polio, fundada em 2000 em Madrid, Espanha. Em nosso estudo qualitativo, analisamos as páginas institucionais de ambas as associações que se encontram em suportes digitais com acesso aberto. Tanto a Abraspp quanto a Asociación Afectados de Polio y Sindrome Post-polio sinalizam como papel principal de sua associação o caráter de divulgadoras de informações sobre a síndrome, tomando para o coletivo a co-elaboração de políticas inclusivas e defesa de direitos de pessoas com deficiência. Foi observado que nas fontes digitais analisadas das associações a SPP não é encampada como síndrome rara.
Deficiência, educação e trabalho na 1ª Conferência Nacional de Educação (1927)
Authors: da Conceição Pizolati Audrei Rodrigo
Published: July 2021

O objetivo desta pesquisa é examinar a questão da educação e da deficiência correlacionadas ao mundo do trabalho nos anos 1920 e seus reflexos na atualidade. Para tanto, lança-se mão teórica e metodologicamente do conceito de normalização em perspectiva ao campo da História da Educação e aos Estudos do Trabalho e Educação. Como materialidade empírica, elencou-se a I Conferência Nacional de Educação (I CNE), realizada em 1927, na cidade de Curitiba e decretos e leis nacionais contemporâneas concernentes à inserção social de deficientes ao mundo do trabalho. A eleição analítica da I CNE decorre do fato de que foi nesse evento que a educabilidade do brasileiro novecentista foi debatida pela primeira vez em âmbito nacional – consoante aos discursos biossociais pautados pelo fordismo e pela eugenia. Assim, todos os indivíduos deveriam contribuir com sua força de trabalho para o progresso econômico do país. Aqueles cuja educação não permitisse a emancipação socioeconômica via laboro, restá-los-iam a reclusão em instituições especializadas como escolas especiais, manicômios ou leprosários. O resultado dessas discursividades apontam, no presente, para uma educação em que o ingresso ao mundo do trabalho ainda permanece como sendo o principal balizador intersocial e de normalidade.

Line intensity mapping (LIM) provides a unique and powerful means to probe cosmic structures by measuring the aggregate line emission from all galaxies across redshift. The method is complementary to conventional galaxy redshift surveys that are object based and demand exquisite point-source sensitivity. The Tomographic Ionized-carbon Mapping Experiment (TIME) will measure the star formation rate during cosmic reionization by observing the redshifted [C ii] 158 μm line (6 ≲ z ≲ 9) in the LIM regime. TIME will simultaneously study the abundance of molecular gas during the era of peak star formation by observing the rotational CO lines emitted by galaxies at 0.5 ≲ z ≲ 2. We present the modeling framework that predicts the constraining power of TIME on a number of observables, including the line luminosity function and the auto- and cross-correlation power spectra, including synergies with external galaxy tracers. Based on an optimized survey strategy and fiducial model parameters informed by existing observations, we forecast constraints on physical quantities relevant to reionization and galaxy evolution, such as the escape fraction of ionizing photons during reionization, the faint-end slope of the galaxy luminosity function at high redshift, and the cosmic molecular gas density at cosmic noon. We discuss how these constraints can advance our understanding of cosmological galaxy evolution at the two distinct cosmic epochs for TIME, starting in 2021, and how they could be improved in future phases of the experiment.
