Cuerpos que migran. desplazamientos sociales y culturales en Víctor Hugo Viscarra y Susy Shock
Authors: Miranda Ana Lía
Published: July 2021

El tema de la migración es un factor fundamental de la literatura latinoamericana, porque nos permite investigar las acciones de los sujetos que experimentan el fenómeno de muchas maneras. Me interesa examinar las expresiones literarias de Víctor Hugo Viscarra, escrita desde la periferia de la Paz (Bolivia) y de Susy Shock (Argentina) que se define como una “artista trans-Sudaca”, porque muestran una movilidad física y en sus modos de conocimiento y condición. Los espacios de escritura que se definen pueden leerse a partir de las categorías de “sujeto migrante” y “heterogeneidad” trabajados por Antonio Cornejo Polar y Raúl Bueno.A su vez, el cuerpo travesti de Susy Shock funciona como un desestabilizador del orden heteronormativo, “buceando” en los intersticios de la oposición binaria del género, mostrándose como un cuerpo que redefine en cada representación performativa; es decir, en su voz y escritura, otros procesos de desplazamiento.

Показано, що пандемія в Україні зумовила нові виклики і посилила ризики сталого поступу територіальних громад, а карантинні заходи поглибили негативні тенденції зміцнення їх фінансової спроможності. Проаналізовано процеси формування і використання фінансових ресурсів територіальних громад України в умовах пандемії. Наголошено на особливостях прояву кризи COVID-19 на місцевому рівні (асиметричний вплив на розвиток територій, негативні фінансово-економічні ефекти, невизначеність у прийнятті фінансово-управлінських рішень). Виявлено тенденції впливу пандемії на фінансові індикатори територіальних громад у розрізі обраних груп (міста обласного значення, міські, селищні та сільські ТГ): скорочення фінансової підтримки місцевих бюджетів з державного бюджету, сповільнення приросту податкових надходжень за основними податками; зменшення обсягів фінансових ресурсів на забезпечення економічного розвитку територій тощо. Ідентифіковано проблеми, які негативно впливають на зміцнення фінансової спроможності громад, серед яких: відсутність вертикальної координації та взаємоузгодженості дій органів державної влади та органів місцевого самоврядування в питаннях протидії наслідкам пандемії та забезпечення розвитку територій; несистемний характер реакції місцевих органів влади на кризові явища; надмірна орієнтація органів місцевого самоврядування на фінансування соціальних видатків і делегованих повноважень з одночасним скороченням обсягів економічного спрямування; низька комунікація органів місцевого самоврядування з мешканцями громад (особливо сільських) в умовах віддаленої роботи. Доведено вплив когнітивних, соціальних і психологічних чинників на прийняття рішень, що притаманно як окремим індивідам, так і групам осіб у частині: обґрунтування несистемного характеру і короткострокової перспективи реакції органів управління різних рівнів на кризу; неповної зайнятості найманих працівників; налагодження системної комунікації влади і мешканців; формування ефективних механізмів взаємодії та підтримки громадян з урахуванням поведінкових уявлень людей.
Aquaporins in regulation of plant protective responses to drought
Authors:   M.G. Kholodny Institute of Botany, National Academy of Sciences of Ukraine, Ovrutska I.I.
Published: July 2021

Plasmolemma permeability is an integral indicator of the functional state of plant cells under stress. Aquaporins (AQPs), specialized transmembrane proteins that form water channels and play an important role in the adaptation of plants to adverse conditions and, in particular, to lack or excess of water, are involved in the formation of the response to drought. The main function of AQPs is to facilitate the movement of water across cell membranes and maintain aqueous cell homeostasis. Under stressful conditions, there is both an increase and decrease in the expression of individual aquaporin genes. Analysis of the data revealed differences in the expression of AQPs genes in stable and sensitive plant genotypes. It turned out that aquaporins in different stress-resistant varieties of the same species also respond differently to drought. The review provides brief information on the history of the discovery of aquaporins, the structure and function of these proteins, summarizes the latest information on the role of aquaporins in the regulation of metabolism and the response of plants to stressors, with particular emphasis on aquaporins in drought protection. The discovery and study of AQPs expands the possibilities of using genetic engineering methods for the selection of new plant species, in particular, more resistant to drought and salinization of the soil, as well as to increase their productivity. The use of aquaporins in biotechnology to improve drought resistance of various species has many prospects.

BACKGROUND AND OBJECTIVES

There is widespread unwarranted antibiotic use and large individual provider variation in antibiotic use in NICUs. Vignette-based research methodology offers a unique method of studying variation in individual provider decisions. The objective with this study was to use a vignette-based survey to identify specific areas of provider antibiotic use variation in newborns being evaluated for early onset sepsis.

METHODS

This study was undertaken as part of a statewide multicenter neonatal antibiotic stewardship quality improvement project led by a perinatal quality improvement collaborative. A web-based vignette survey was administered to identify variation in decisions to start and discontinue antibiotics in cases of early onset sepsis.

RESULTS

The largest variation was noted in 3 of the 6 vignette cases. These cases highlighted variation in (1) decisions to start antibiotics in a case describing a well-appearing newborn with risk factors and an elevated C-reactive protein, (2) decisions to start antibiotics in the case of a newborn with risk factors plus mild respiratory signs at birth, and (3) decisions to stop antibiotics in the case of the newborn with a history of sepsis risk factors and mild clinical respiratory signs that resolved after 72 hours.

CONCLUSIONS

Clinical vignette assessment identified specific areas of variation in individual provider antibiotic use decisions in cases of suspected early onset sepsis. Vignettes are a valuable method of describing individual provider variation and highlighting antibiotic stewardship improvement opportunities in NICUs.
Psychiatric Phenotypes of Pediatric Patients With Seropositive Autoimmune Encephalitis
Authors: Adams Ashley V. , Van Mater Heather , Gallentine William , Mooneyham GenaLynne C.
Published: July 2021

OBJECTIVES

Patients with autoimmune encephalitis (AE) often present with symptoms that are broadly characterized as psychiatric or behavioral, yet little attention is given to the precise symptomatology observed. We sought to more fully define the psychiatric symptoms observed in patients with anti–N-methyl-D-aspartate receptor (NMDAR), anti–glutamic-acid-decarboxylase 65 (GAD65), and anti–voltage-gated-potassium-channel complex (VGKC) antibody-mediated AE using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition nomenclature.

METHODS

We present a case series (n = 25) using a retrospective chart review of 225 patients evaluated for AE in a tertiary care academic medical center between 2014 and 2018. The included patients were ≤18 years old with anti-NMDAR AE (n = 13), anti-GAD65 AE (n = 7), or anti-VGKC AE (n = 5). The frequency of neuropsychiatric symptoms present at the onset of illness and time to diagnosis were compared across groups.

RESULTS

Psychiatric symptoms were seen in 92% of patients in our cohort. Depressive features (72%), personality change (64%), psychosis (48%), and catatonia (32%) were the most common psychiatric symptoms exhibited. On average, patients experienced impairment in ≥4 of 7 symptom domains. No patients had isolated psychiatric symptoms. The average times to diagnosis were 1.7, 15.5, and 12.4 months for anti-NMDAR AE, anti-GAD65 AE, and anti-VGKC AE, respectively (P < .001).

CONCLUSIONS

The psychiatric phenotype of AE in children is highly heterogenous. Involving psychiatry consultation services can be helpful in differentiating features of psychosis and catatonia, which may otherwise be misidentified. Patients presenting with psychiatric symptoms along with impairments in other domains should prompt a workup for AE, including testing for all known antineuronal antibodies.

Published: July 2021

Visual development begins at birth and continues throughout childhood. Ocular pathology can lead to permanent visual impairment and subsequent problems in overall development and school performance as well as signify serious systemic disease or even life-threatening malignancies. Prompt identification of congenital or early acquired ocular pathology via regular bedside ocular examinations and assessments of visual behaviors by neonatal clinicians is a critical component of newborn care. The goal of this article is to review the components of the newborn eye examination, describe key ocular findings and diagnoses that are common or critical to identify in the newborn period, and offer guidance on necessity and timing of ophthalmology referral.
Educação inclusiva

Published: July 2021

Este artigo se propõe a relacionar o debate da educação com o modelo de sociedade do capital e, para isso, parte de uma determinada experiência de atuação na área do ensino superior público. Esse ponto é disparador para adentrar no modelo de educação e, consequentemente, no campo da inclusão na educação. Faz-se sinalizações sobre a contradição inerente aos conflitos e complexidades que constituem essas temáticas, demarcando o antagonismo do que é preconizado na concepção de educação inclusiva, com a declarada intenção do capital em subordinar a educação, cada vez mais, à mercadoria. Ao estender a análise, são realizados apontamentos sobre as barreiras de acesso, bem como o desenvolvimento de medidas que possibilitam melhores condições de acessibilidade aos estudantes com deficiência no ensino superior.
A atualidade da estratégia baseada na dualidade de poder
Authors: Dillenburg Fernando Frota
Published: July 2021

O objetivo desse artigo é tratar do significado do fenômeno do “duplo poder”, algo presente desde as revoluções burguesas até as revoluções proletárias. Os sovietes (conselhos) de trabalhadores das Revoluções Russas de 1905 e 1917 ganham destaque no texto como exemplos da dualidade de poder. A questão que surge é se toda a revolução proletária deve necessariamente passar por um momento de duplo poder, ou, ao contrário, o choque entre dois Estados é algo que se tornou anacrônico. O texto contém observações de autores que participaram ativamente de revoluções, como Marx, Engels, Lênin, Trotsky, Zinoviev, Rosa Luxemburgo e Gramsci, além de diversos comentadores. Com este texto pretende-se contribuir com o debate sobre a estratégia a ser assumida pelo proletariado mundial.

News Text: Genre Transformation
Authors: Volkova Yana , Panchenko Nadezhda
Published: July 2021

The article considers a news text as a secondary type of text where news content undergoes modifications as a result of humorous interpretation. New trends in media coverage, which lead to a change in its format and linguistic content, are analyzed. The creation of a secondary news text / genre is shown as performed through transforming the main (primary) news text. The secondary media text belongs to the comic picture of the world, the modeling of which becomes possible due to various means of the comic which fulfill social-critical, aesthetic and entertainment functions. The empirical material of the study comprises 530 news texts telecast at the beginning of the program "Evening Urgant" on Channel One in 2017–2020. The identified mechanism of news transformation includes the use of irony, sarcasm, comic exaggeration and understatement, references to precedent phenomena, the techniques of allegory, comic dissonance and comic surprise, comic exposure, etc. The analysis of the news transformation mechanism revealed a reduction in the primary news component with a simultaneous "build-up" of a pragmatic component through the use of various means and techniques of the comic. This leads to the construction of a secondary news text, which, in turn, is characterized by a recombined semantic content and subjective interpretation of the primary news piece.

Authors: Cho Yong Jin , Song Dong Won
Published: July 2021

Objective: Several studies suggested that heart rate variability (HRV) is a risk factor for metabolic syndrome. The objective of this study was to evaluate the association between HRV and metabolic syndrome among Korean adults.Methods: We included 6,945 people who visited the Soonchunhyang University Cheonan Hospital Health Examination Center and tested HRV, from March 2016 to November 2019. Among them, 6,827 subjects were included. We excluded those who had a history of hypertension, diabetes, stroke, or other disease and excluded them from the omission of questionnaires. We examined HRV with machine WISE-8000 (MooYoo Instruments, Seongnam, Korea) and divided three groups of HRV results. The diagnosis of metabolic syndrome was made using criteria modified National Cholesterol Education Program Adult Treatment Panel III. Logistic regression analysis was used to calculate odds ratios between HRV results and metabolic syndrome.Results: The odds ratio for metabolic syndrome in low HRV result was 2.87 (95% confidence interval [CI], 1.87–3.34) compared with high HRV result. After adjustment for age, smoking, alcohol consumption, and physical activity, the odds ratio for metabolic syndrome in low HRV result was also 3.37 (95% CI, 2.44–4.65) compared with high HRV result.Conclusion: Low HRV result using WISE-8000 (MooYoo Instruments) showed an increased risk for metabolic syndrome. HRV was associated with an increased risk of metabolic syndrome in Korean adults.

Authors: Jung Yoo Ra , Lee Sun Hyang , Park Ga Young , Kim Sung Shin
Published: July 2021

In the case of hemodynamically stable broad complex tachycardia, it is essential to evaluate the causes and to diagnose correctly in the selection of appropriate management and drugs. We report two neonates diagnosed with idiopathic ventricular tachycardia, which is extraordinarily rare. One presented with idiopathic fascicular ventricular tachycardia (right bundle branch block pattern with a superior axis), and the other presented with right ventricular outflow tract ventricular tachycardia (left bundle branch block pattern with an inferior axis). These two forms are representative of benign ventricular tachycardia. No features of cardiovascular shock were observed. While the recommended initial drug treatments are different, the conditions were well controlled by propranolol without the development of any adverse events. There was no recurrence of arrhythmia for several months in the outpatient clinic.
Postoperative Thrombotic Microangiopathy with the Combined Administration of Tranexamic Acid and Batroxobin: Two Case Reports
Authors: Heo Min Hee , Kim Jung Hyeon , Kim Ji Yeon
Published: July 2021

Thrombotic microangiopathy (TMA) is a clinical syndrome characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage. When TMA is suspected, accurate diagnosis is required; however, differential diagnosis is often difficult because each patient has various clinical features, and the causes of triggers may overlap. We report two cases of TMA that developed after surgeries in patients, with the combined administration of tranexamic acid and batroxobin intraoperatively. We need to consider the risk of adverse effects of the concomitant use of tranexamic acid and batroxobin for anesthetic management.
Sodium-Ion Batteries: Current Understanding of the Sodium Storage Mechanism in Hard Carbons
Authors: Fitzpatrick Jack R. , Costa Sara I. R. , Tapia-Ruiz Nuria
Published: July 2021

In recent years, sodium-ion batteries (NIBs) have been explored as an alternative technology to lithium-ion batteries (LIBs) due to their cost-effectiveness and promise in mitigating the energy crisis we currently face. Similarities between both battery systems have enabled fast development of NIBs, however, their full commercialisation has been delayed due to the lack of an appropriate anode material. Hard carbons (HCs) arise as one of the most promising materials and are already used in the first generation of commercial NIBs. Although promising, HCs exhibit lower performance compared to commercial graphite used as an anode in LIBs in terms of reversible specific capacity, operating voltage, initial coulombic efficiency and cycling stability. Nevertheless, these properties vary greatly depending on the HC in question, for example surface area, porosity, degree of graphitisation and defect amount, which in turn are dependent on the synthesis method and precursor used. Optimisation of these properties will bring forward the widespread commercialisation of NIBs at a competitive level with current LIBs. This review aims to provide a brief overview of the current understanding of the underlying reaction mechanisms occurring in the state-of-the-art HC anode material as well as their structure-property interdependence. We expect to bring new insights into the engineering of HC materials to achieve optimal, or at least, comparable electrochemical performance to that of graphite in LIBs.
Nonlinear Unemployment Effects of the Inflation Tax
Authors: Ait Lahcen Mohammed , Baughman Garth , Rabinovich Stanislav , van Buggenum Hugo
Published: July 2021

We argue that long-run inflation has nonlinear and state-dependent effects on unemployment, output, and welfare. Using panel data from the OECD, we document three correlations. First, there is a positive long-run relationship between anticipated inflation and unemployment. Second, there is also a positive correlation between anticipated inflation and unemployment volatility. Third, the long-run inflation-unemployment relationship is not only positive, but also stronger when unemployment is higher. We show that these correlations arise in a standard monetary search model with two shocks – productivity and monetary – and frictions in labor and goods markets. Inflation lowers the surplus from a worker-firm match, in turn making it sensitive to productivity shocks or to further increases in inflation. We calibrate the model to match the U.S. postwar labor market and monetary data, and show that it is consistent with observed cross-country correlations. The model implies that the welfare cost of inflation is nonlinear in the level of inflation and is amplified by the presence of aggregate shocks.
Strategic significance of port infrastructure in social and economic development of the Russian Federation and its regions
Authors: Goncharova A. R. , Stoyanova I. А.
Published: July 2021

Transit communications and infrastructure facilities are basic conditions of countries’ spatial social and economic development. Cargo transportation services make up more than 50 per cent of the global export of transport services. Unique geographical position of Russia between Europe and Asia, existing border sea routes provide the country with the opportunity to become a part of global traffic flows and, thus, maintain the development of transit and export-import potential bound to the “entry points” into the world transport system. Domestic sea ports’ activities and their rapid modernization development can be predicted due to the fact that being part of the infrastructure they maintain communication in the area and the national economy’s integration into the global economy. Each sea bordering region of the Russian Federation solves the problems of developing separate ports. In the south they pay great attention to development of transport potential of the region by means of complex development of regional transport hubs, in particular, creating special economic port areas. Northern regions are more oriented towards developing the Northern Sea Route ports which provide exploration and production of hydrocarbons, and arrange northern supply to hard-to-reach regions. The Baltic region is characterized by tough competition with the Baltic states’ ports, and they have to reinforce import-export and transit potential of the country connected with the emerging positive changes in the direction of freight traffic. In perspective, the North-West Federal District is supposed to become a platform for several large-scale strategic infrastructural projects. As a result, a transport and transit area will be created to increase the volume of international and domestic transportation and the throughput of the regional seaports. Life-supporting function of port infrastructure is the strategic factor of the development of the total transport system of Russia due to its vast territory. Therefore, strategic regulation and programs have been developed at the federal level. They function as valid regulatory legal acts, are part of the total state government system and maintain national security and connectedness of Russian territory and stable economic growth. Strategic significance of these documents for sustainable social and economic development of the Russian Federation and its regions required analysis and systematization of Decrees, Strategies and Programs from the viewpoint of infrastructural factor of construction and modernization of Russian sea ports.
Management of based on public private partnership auto-recycling projects
Authors: Savon D. Yu. , Kolotyrin K. P. , Sakhno E. S.
Published: July 2021

The article is devoted to the acute problem connected with managing autorecycling projects in accordance with the environmental security requirements and economic effectiveness. Lately, the problem of environmentally-friendly recycling of used automotive components has become very urgent in Russia due to the increasing number of cars in the country. The existing car recycling programs do not solve this problem as they deal with cars and do not recycle separate car components. Environmental fee (or eco fee) existing in our country does not cover all range of used automotive components as well, and the existing organizational and economic autorecycling mechanism makes it impossible to solve environmental problems according to the market approach in full. Therefore, it is essential to develop a mechanism for managing autorecycling projects which would involve both effective market approaches and the state ones. To this end, the authors suggest exploiting public-private partnership (PPP) to increase environmental and economic efficiency in implementing autorecycling projects. The focus is made on such forms of public-private partnership as delegation of control and concession. It is suggested to make concession of infrastructure facilities and areas for stocking used automotive components which are not recyclable. Some government functions in managing automotive components’ sorting can be delegated as well as management of finance. As a result, exploiting PPP tools in managing autorecycling projects will provide the opportunity for maintaining “transparency” of financial flows in handling used automotive components, recyclers will be encouraged to introduce safe and modern recycling technologies and the level of environmental risks in managing autorecycling projects will be reduced.

Comparing critical speed modelling approaches and exploring relationships with match-play variables in elite male youth soccer players
Authors: Liu Ka-Chun , Sheard Jake , Piatrikova Eva , Williams Sean , Parr James , Roe Gregory , Kramer Mark , Luna Eva , Milton Paddy , Frixou Theo
Published: July 2021

Background: A novel bi-exponential method has emerged to estimate critical speed (CS) and D-prime (D′) from a 3-min all- out test (3MT).

Objectives: To compare CS analysis methods to determine whether parameter estimations were interchangeable. Reference values and relationships with key soccer match- play variables were explored.

Methods: Thirteen elite male youth (14-15 years old) players completed a 30 m shuttle run 3MT to estimate CS, D′, rate of speed decline time constant, maximal speed (Smax), time to Smax (tmax), and fatigue index (FI), using the traditional method and bi-exponential model on average (Bi-ExpAverage) and max speed settings (Bi-ExpMax-Speed). High-speed running (HSR) and sprinting distances and counts, and the number of accelerations were collected from two matches. Magnitude- based inferences (p < 0.05) with smallest worthwhile change of 0.2 effect sizes were used to analyse differences. Pearson’s and Spearman’s correlation coefficients were used to measure associations between CS model variables and match-play parameters.

Results: There were significant differences between the traditional method and both bi-exponential models for CS and D′, as well as between the bi-exponential models for all variables except tmax. Using the Bi-ExpAverage model, strong correlations (r = 0.70-0.73; p < 0.05) were observed for D′ and FI with the number of standardised and individualised HSRs, respectively. With the Bi-ExpMax-Speed model, there were strong correlations (r/ρ = 0.64-0.68; p < 0.05) between D′ and the number of standardised HSRs and sprints, and the number of individualised sprints.

Conclusion: There is a lack of interchangeability between analysis methods. It appears that D′ and FI from the bi- exponential models could be associated with high-intensity actions in soccer match-play.
The use of 4-methylbenzenesulfonate ionic liquid derivatives as environmentally friendly corrosion inhibitors for mild steel in hydrochloric acid
Authors: Nesane T. , Mnyakeni-Moleele S.S. , Murulana L.C.
Published: July 2021

The effectiveness of two synthesized ionic liquids, 1-(benzyloxy)-1-oxopropan-2-aminium 4-methylbenzenesulfonate (1-BOPAMS) and 4-(benzyloxy)-4-oxobutan-1-aminium 4-methylbenzenesulfonate (4-BOBAMS), were evaluated for mild steel corrosion inhibition in 1.0 M hydro-chloric acid solution, using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and gravimetric techniques. Organic moieties responsible for the adsorption process on mild steel surface were investigated using Fourier transform infrared spectroscopy (FTIR). Gravimetric analysis revealed that the inhibition efficiency of 1-BOPAMS and 4-BOBAMS increased with concentration, with maximum inhibition values of 90.32% and 97.91%, respectively, at the highest concentration of the inhibitors. Gibbs free energy (nG°ads) values indicated a strong interaction between the mild steel surface and the molecules of the ionic liquids, and that the adsorption process was spontaneous. These values also show that the inhibitive nature of ionic liquids against mild steel corrosion is caused by a mixedtype of adsorption film formed on the steel surface. The Langmuir adsorption isotherm was used to describe the adsorption of ionic liquid molecules onto the mild steel surface. Polarization curves showed that 1-BOPAMS and 4-BOBAMS have a similar effect on both the anodic and cathodic half-reactions, indicating that they prevent the dissolution of mild steel through both physical and chemical process. Nyquist plots were defined by incomplete semicircle capacitive loops, showing that the charge transfer mechanism controls the corrosion of mild steel in acidic solution.
A new grade-capping approach based on coarse duplicate data correlation
Authors: Dutaut R.V. , Marcotte D.
Published: July 2021

In most exploration or mining grade data-sets, the presence of outliers or extreme values represents a significant challenge to mineral resource estimators. The most common practice is to cap the extreme values at a predefined level. A new capping approach is presented that uses QA/QC coarse duplicate data correlation to predict the real data coefficient of variation (i.e., error-free CV). The cap grade is determined such that the capped data has a CV equal to the predicted CV. The robustness of the approach with regard to original core assay length decisions, departure from lognormality, and capping before or after compositing is assessed using simulated data-sets. Real case studies of gold and nickel deposits are used to compare the proposed approach to the methods most widely used in industry. The new approach is simple and objective.

Projects or project-orientated approaches have become a common form of work in nearly all sectors of economies. This has led to concepts such as 'projectified' and 'project orientated' organizations. By defining projectification of a company, industry, or economy as the share of project work in total work, one can reasonably determine the impact that project management, and by default projectification, has had on that company, industry, or economy in terms of staff optimization and allocation. This paper presents the results for such a projectification study of the South African mining industry. This sector has long been a significant contributor to the country's economy from a gross value added (GVA) and employment point of view. Understanding the impact of projectification and the project management way of work on this industry may potentially add significant value to both the mining and project management knowledge areas. We show that although the mining industry is considered by some to operate in archaic ways, the level of projectification has increased over time, and now represents approximately one third of all work conducted.

A steady trend towards the development of electric power systems leads to their continuous enlargement and sophistication. As a result, new ways of their control appear. In this regard, the existing models and complexes for adequacy assessment may work inadequately and ineffectively in terms of the obtained results adequacy. To assess the current state of the existing models and complexes, we reviewed and analyzed the domestic and foreign software and computer systems. In particular, we considered mathematical models of minimizing the power shortage. This work is based on the problem of modifying mathematical models of minimizing the power shortage used in adequacy assessment of the electric power systems of one of the complexes under consideration. As a modification of mathematical models, it is proposed to exclude the existing method of using the line capacities and start use correct accounting for the maximum permissible active power flow in controlled sections. The experimental part reflected in the paper concerns the testing of options for models to minimize the power shortage, as well as the proposed modifications on various systems, including those consisting of three and seven reliability zones with a variable number of controlled sections and power lines included in them. The results of the study have shown that the proposed modifications are efficient and can be used in the future. The authors also obtained the most adequate results in terms of the physical laws of electric power system operation due to the model of minimizing the power shortage with quadratic losses which takes into account the limitations of power transmission over controlled sections.

Factors and Routes of Interregional Migration of University Graduates in Russia
Authors: Antosik Liubov , Ivashina Natalya
Published: July 2021

Data from Russia’s Portal for Monitoring Employment of University Graduates isused to analyze migration of youths between 2013 and 2015. Interregional mobility of human resources stems, in particular, from uneven distribution of universities across the country and socioeconomic disparities between regions. Migration of university graduates may deprive some regions of much of their skilled workers. The largest migration flows are observed between Moscow, St. Petersburg, and Moscow Oblast. Apart from federal cities, graduates are also attracted by industrial regions of the Russian North. This study makes use of a modified gravity model that includes various socioeconomic indicators of home and recipient regions in addition to the basic gravity model factors. Gravity modelling allows identifying a number of migration factors associated with the areas of origin and destination. Origin factors (the ones that push, or repel, graduates out of the region) include low wages and high rates of poverty and unemployment. Destination factors (the ones that pull, or attract, graduates into the region) are represented by high wages and high levels of cultural development and business innovation. Most often, university graduates migrate from south to north and from east to west. Federal subjects of Russia differ essentially by the demand for graduates in regional labor markets. Analysis reveals which regions of Russia attract or repel academic migrants. Territories with consistently diminishing populations of skilled workers are in urgent need for dedicated programs to attract young professionals from other regions, new high-performance jobs, and improvements in the quality of life.
As TIC na formação inicial de educadores e professores

Published: July 2021

A Competência Digital dos educadores e professores é cada vez mais convocada para a renovação das práticas educativas, pelo que urge preparar futuros docentes para uma escola integrada na sociedade digital. Este estudo tem como propósito conhecer a opinião de futuros docentes relativamente aos seus saberes e uso de tecnologias educativas nas práticas educativas para identificar fatores inibidores e propulsores do uso de tecnologia digital. O presente artigo surge no âmbito do Projeto IFITIC que tem como objetivo repensar a prática educativa com TIC na formação inicial de futuros docentes de modo a promover a renovação metodológica na Educação Pré-escolar e no 1.º e 2.º Ciclos do Ensino Básico. Trata-se de um estudo quantiqualitativo cujos dados foram recolhidos através de inquérito por questionário, no ano letivo de 2017/2018, com questões abertas e fechadas, aplicado em três instituições de Ensino Superior Público, responsáveis pela formação inicial docentes, duas do Norte de Portugal e uma do Norte de Espanha. Neste artigo, tratamos alguns dados relativos a 111 estudantes portugueses em formação inicial de professores, recorrendo a uma abordagem estatística descritiva. A informação obtida permite-nos concluir que existem fatores que inibem a integração de recursos digitais nas práticas educativas e outros impulsores de tais práticas. Esperámos contribuir para uma reflexão sobre o uso das TIC na formação inicial docente.
Análisis del proceso de digitalización de un centro de Enseñanza Secundaria desde el modelo DigCompOrg
Authors: Fernández-Miravete Ángel David , Prendes-Espinosa Mª Paz
Published: July 2021

El logro de una competencia digital entre el alumnado se ha convertido en un objetivo principal dentro de las políticas educativas españolas de las últimas décadas. A este respecto, el Marco Europeo para Organizaciones Educativas Digitalmente Competentes (DigCompOrg) guía a los centros educativos en su proceso de digitalización de forma sistemática. Este trabajo evalúa el uso de las tecnologías de aprendizaje de un centro de enseñanza secundaria de la Región de Murcia (estudio de caso) según las dimensiones contempladas en el modelo europeo. El diseño de la investigación se fundamenta en el modelo ADDIE y escoge una metodología mixta en la que se aplican técnicas de tipo cuantitativo (cuestionario SELFIE) y cualitativo (grupo de discusión). Los resultados que se presentan aquí recogen el análisis de la información cualitativa del alumnado de Enseñanza Secundaria Obligatoria, profesorado y equipo directivo. Esta primera etapa de detección de necesidades ha permitido al centro establecer un proceso de autorreflexión y autoevaluación sobre su proceso de digitalización, así como la propuesta de acciones y estrategias de mejora que refuercen su compromiso con las pedagogías digitales. Entre ellas destaca el desarrollo de una estrategia digital de centro, establecer mecanismos de evaluación del progreso o trabajar con tecnologías de aprendizaje digital que fomenten la autoevaluación y coevaluación, acciones todas ellas relacionadas con las dimensiones de liderazgo y prácticas evaluativas del modelo europeo.

Background:The gut microbiota is a key player in the regulation of metabolism, immunity and brain functions. Our previous studies have shown that chronic alcohol abuse induces a leaky gut and alterations of the gut microbiota composition, which are correlated with the severity of psychological symptoms, suggesting the involvement of the gut-brain axis in the development of alcohol use disorder (AUD). Objectives:The Gut2Brain study aims at supplementing AUD patients with prebiotics (inulin) in order to 1) modulate the gut microbiota composition and 2) to evaluate its effect on gastrointestinal tolerance, patient behaviour, biological markers and nutritional intake. Design:A randomized, double-blind, placebo-controlled study included 50 AUD patients hospitalized for a 3-week detoxification program (Brussels, Belgium). Patients were assigned to the inulin (n=25) or placebo group (maltodextrin, n=25). Recruitment was completed in December 2019. Methods: Change in gut microbiota composition will be assessed using microbial 16S rRNA gene sequencing. Biological (metabolites, cytokines and liver function), psychological measurements and dietary anamnesis will be performed at the beginning and the end of the detoxification program (17 days of supplementation). Gastrointestinal tolerance will be assessed throughout the follow-up. The Gut2Brain study was approved by the local ethics committee (2017/04JUL/354) and is registered at www.clinicaltrials.gov as NCT03803709. Keywords: Prebiotic; Inulin; Alcohol use disorder; Gut microbiota; Nutrition; Psychological symptoms; Liver function; inflammation
Age-related Peculiarities of a Delinquent Personality's Preparedness to Resocialize in the Post-penitentiary Period
Authors: Soroka A.V.
Published: July 2021

This article is an incomplete presentation of the second part of the follow-up study on the evidence of age-related peculiarities of personality's preparedness to resocialize during the post-penitentiary period. Earlier, we were able to create and successfully test psychodiagnostic and psychocorrective programs for the resocialization of a delinquent person at the stage of release from prison. The A.R. Ratinov's value and standards theory of a criminal's personality is used as a basis for analysis and comparison of the subjects' system of value orientations. 201 individuals have been examined. The obtained results indicate that the subjects have lowered values in three categories of cognitive concept of personality's basic beliefs. The significance of the age factor in the subjects has been reliably found in such scales as «a tendency to force others to fit one's wants/tastes», «a tendency to change others», «categoricalness towards others», «inability to adjust oneself to others» and so on. Subjects have been found with manifestly excessive predisposition to aggression.
