Skeletal muscle and fiber type-specific intramyocellular lipid accumulation in obese mice
Authors: Umek Nejc , Horvat Simon , Cvetko Erika
Published: May 2021

In obesity, accumulation of lipid droplets in skeletal muscle fibers and a shift towards fast muscle fiber types can both contribute to insulin resistance. However, it is not yet clear how intramyocellular lipid accumulation and fiber type changes are associated. Therefore, we investigated to what extent the lipids accumulated in a fiber type-specific manner in the functionally similar fast-, intermediate- and slow‑twitch gastrocnemius, plantaris, and soleus muscles, respectively, in high-fat diet-induced obese 54-week-old female C57BL/6JOlaHsd mice (n=9) compared to control standard-diet-treated lean mice (n=9). A high-fat diet was administered for 26 weeks. Fiber-type specific intramyocellular lipid content analysis and muscle fiber typing were performed using histochemical analysis of lipids with Sudan Black and immunohistochemical analysis of myosin heavy chains on serial sections of skeletal muscles. Compared to the lean mice, the lipid accumulation was most prominent in types 2a and 2x/d fibers (p<0.05) of fast-twitch gastrocnemius and intermediate plantaris muscles in the obese mice, while in slow-twitch soleus muscle, there was no significant lipid accumulation in the obese animals. Furthermore, the slow-twitch soleus muscle of the obese mice with no significant change in muscle fiber diameters exhibited the most pronounced shift towards fast-type myosin heavy chain isoform expression (p<0.05). In contrast, the fast-twitch and intermediate-twitch gastrocnemius and plantaris muscles, respectively, in which the muscle fiber diameters increased (p<0.05), were more resistant toward myosin heavy chain expression changes. In conclusion, we demonstrated both muscle- and fiber-type specificity in intramyocellular lipid accumulation in obese mice, suggesting that in obesity, similar muscle fiber types in different muscles accumulate lipids differentially.

Published: May 2021

Subject. In the marketing activities of enterprises in the manufacturing sector of the economy, a special place is occupied by the formation of a product policy. Its development is associated with the research of the possibilities and directions of digitalization of product development processes, product lifecycle management and product range optimization. Purpose. Analysis of the possibilities of applying digital methods in the main directions of a product policy, identification of prob-lems of accessibility of digital technologies for companies of various scales of economic activity and search for ways to solve them. Methodology. A systematic approach, general logical and empirical methods were used. The analysis of scien-tific and practical materials and experience of enterprises was carried out. Results. Тhe effectiveness of the product policy of a modern enterprise depends largely on the degree of use of digital technologies at all stages of the creation and market support of products. Their practical application is constrained by a number of fac-tors: management's underestimation of the role of marketing and marketing infor-mation; insufficient level of "digital" competence of employees engaged in infor-mation support and analytics; lack of resources to purchase expensive software products or pay for outsourcing of marketing research. Today, the most popular is the web analytics of the company's website, which mainly covers the area of prod-uct/service promotion. In the field of the product policy, the degree of digitalization of processes and methods of obtaining information is significantly lower. Digitalization of the processes of selecting ideas for new products and improving existing ones, developing a marketing concept for the product, segmenting the market and positioning the product, optimizing the production nomenclature and assortment is still an insufficiently developed area of product policy and in the fu-ture can ensure the effectiveness of the "customer value delivery system". Conclusions. The market orientation of the business involves a strategic approach to the formation of the product range, the development of new products and their introduction to the market. The use of digital technologies at all stages of the for-mation of product policy makes it possible to increase the competitiveness of products and realize the goal of marketing with lower costs. The development of a commodity policy based on digital technologies is hindered by a number of prob-lems related to the insufficient level of information systems, the lack of qualified specialists and the unavailability of technologies due to limited resources.
Comprehensive image of state power as a tool of social management
Authors: Mishon Elena V.
Published: May 2021

Importance. The practice of recent years clearly demonstrates the tendency of the population to decline in confidence in the activities of the authorities. The further development of this process is unacceptable, since in such a case the work of all state structures becomes ineffective even if it is absolutely expedient and justified. The reasons for public distrust of the authorities can be divided into three groups: communicative, organizational and cultural-historical problems. Communicative problems arise due to violations or disregard for the requirements of communication theory. Organizational difficulties in the vast majority of cases are associated with the low qualification of specialists responsible for interacting with society (usually PR specialists or public relations specialists). Cultural and historical problems are due to the dominance in our society of an established model of behavior of citizens, which stably reproduces the situation of opposition to the authorities. In our opinion, the most significant group - communication problems - requires priority attention. Perpose. Communication problems arise from the misplaced positioning of power structures, that is, from the inability to clearly and arguably explain the significance and appropriateness of planned or already implemented measures. Accordingly, it is necessary to identify/develop, in a short time, technologies, methods and tools to eliminate communication barriers, and in some cases communication failures, public-governmental interactions. Research methodology. To achieve the goal, the author's approach was applied, which is based on the principles of systematics, flexibility, mobility and adequacy (they served as the basis for the need to develop an integrated image). The theoretical base is the works of domestic and foreign scientists in the field of public relations management [11,12,14,15,16,17,18,19]. Methods for the study of soft systems are used: theoretical typology, formal extrapolation, factographic methods based on information analysis (analogy method, content analysis), forsyth modeling (technology for working with images of the future. Results. In order to increase the rating of public confidence in the activities of state structures based on the study, systematization and analysis of the causes and consequences of communicative failures and barriers to effective interaction between these switches, an approach based on the principles proposed by the author (systematics, adequacy, flexibility, mobility) and the use of such a social management tool as image is proposed. An option of developing a comprehensive image of the state structure, including a corporate and personal image, has been proposed and justified. Its development technology is recommended, providing an integrated approach to solving the problem of effective interaction using modern public relations management tools.

A new stage of innovative development based on end-to-end digital technologies, the application of artificial intelligence actualizes the study of changes in the structure of resources necessary for the successful provision of this process, and above all intellectual capital. Objectives. Research of the structure of in-tellectual capital, its changes in the conditions of digitalization of the economy. The study of the formation of digital capital of the organization, the analysis of in-stitutional transformations that provide conditions and incentives for the accumula-tion of intellectual capital of a new quality. Methods. Methods of the following scientific approaches were used for the research: dialectical, systemic and institutional, as well as methods of analysis and synthesis. The research is based on the study of current scientific and periodical economic literature. Conclusions and Relevance. The structure of intellectual capital in the modern economy is investi-gated, its elements are justified, the emergence of digital capital as a new structural element that ensures the competitiveness of firms in the period of large-scale digi-talization of the economy. The content of digital capital is revealed, the conditions and limitations of its formation in the modern Russian economy are revealed. The effectiveness of the process of forming the structure of intellectual capital requires the optimization of its structural elements in the activities of modern organizations, in some cases, large-scale restructuring. The objective need of enterprises in the conditions of digitalization to ensure competitiveness is the formation of digital capital corresponding to the scale and content of economic activity. The success of this process depends on overcoming the resistance to changes of the organization's employees, creating favorable institutional conditions that ensure, first of all, an increase in incentives and interest in the accumulation of intellectual capital of a new quality, the active formation and use of its most dynamic and significant part-digital capital.

Избыточная смертность в России в праздничные дни
Authors: Немцов Александр Викентьевич , Симонов Анатолий Никифорович , Фаттахов Тимур Асфанович , Гридин Роман Владимирович
Published: May 2021

Постановка проблемы. Известно, что праздники сопровождаются ростом заболеваемости и смертности. Целью данного исследования являлось обобщение опыта предыдущих работ, изучающих связь между национальными праздниками и временем смерти, а также анализ российских особенностей смертности в праздничные дни. Мы ставили следующие вопросы: 1) «увеличивается ли в России риск умереть в праздники?»; 2) «если да, то в какие?»; 3) «связано ли это со злоупотреблением алкоголем?»; 4) «в какой степени в это вовлечены мужчины и женщины?»; 5) «какова оценка избыточного числа смертей в праздничные дни?».

Методы. В исследовании использованы ежедневные данные о числе умерших в России от всех причин и от алкогольных отравлений с разделением по полу за 2000-2017 гг. Всего в рассматриваемый период умерло 35,4 млн человек. Исследовали 9 государственных праздников в России. За ноль отсчета принимали скользящую среднюю LOWESS, рассчитанную для непраздничных дней и экстраполированную на праздничные дни. Учитывали праздничные дни, которые превышали доверительный интервал LOWESS. Для оценки потерь в день рождения за ноль отсчета принимали линейную регрессию и ее доверительный интервал. Для косвенной оценки легального и нелегального потребления алкоголя использовали данные Росстата о помесячных продажах алкогольной продукции и данные Google Trends о популярности поисковых запросах на алкогольную продукцию.

Результаты. Пять из девяти государственных праздников в России сопровождаются ростом числа смертей. Наибольший рост наблюдается 1-15 января в связи с Новым годом. В это время избыточное число смертей составило 113,6 тыс. человек за 18 лет или 6,3 тыс. человек в год с максимумом 1 января (2,0 тысячи в день). Это на 14,0% больше, чем в будни. В праздники 23 февраля, 8 марта и 9 мая избыточное число смертей составило в сумме 1,7 тыс. в год. 80,9% избыточных смертей в январе приходится на мужчин. Общая смертность и смертность при отравлении алкоголем совпадает по максимуму 1 января и в последующей динамике. После 2005 г., когда увеличилась продолжительность новогодних праздников, максимум 1 января и последующая динамика смертности не изменилась. Годовой максимум продаж алкогольных напитков приходится на декабрь. Дни рождения также сопровождаются приращением общей смертности на 11,1 тыс. в год, и это также связано с алкоголизацией.

Заключение. В России в праздники, главным образом новогодние и дни рождения, происходит значительный прирост смертности, который обусловлен преимущественно злоупотреблением алкоголем и не зависит от продолжительности праздников в январе. Снизить этот урон может уменьшение доступности крепкого алкоголя, максимум продаж которого приходится на декабрь.
Разрыв в ожидаемой продолжительности жизни мужчин и женщин: обзор генетических, социальных и ценностных факторов
Authors: Зинькина Юлия Викторовна , Коротаев Андрей Витальевич
Published: May 2021

Женское преимущество в ожидаемой продолжительности жизни (ОПЖ) встречается во всем мире, несмотря на различия в условиях жизни, положении женщин и действие других факторах. Однако это преимущество уменьшилось в последние годы в странах с низким уровнем смертности. При этом давно установлено, что, хотя женщины живут дольше мужчин, уровень заболеваемости (morbidity) у них выше. Существует значительное число исследований, позволяющих с уверенностью утверждать, что в основе данного парадокса лежат как биологические факторы, так и социальные явления и процессы. Среди биологических факторов отмечаются гормональные (преобладание эстрогенов по сравнению с андрогенами, более низкий уровень у женщин тестостерона, связанного с рискованным поведением) и кариотипические различия (к примеру, прогрессивное искажение инактивации X-хромосомы, истощение теломер, митохондриальное наследование и др.). Значительный вклад вносит поведение в области здоровья: мужчины реже обращаются к врачам, реже контролируют уровень холестерина и кровяное давление, имеют менее здоровый рацион и чаще склонны к рискованному поведению. Особый вклад вносят курение (в России, по некоторым оценкам, обусловливает до 5 лет разрыва в ОПЖ между мужчинами и женщинами, для Европы также отмечается как наиболее важная причина гендерных различий в смертности) и потребление алкоголя (мужчины пьют чаще, чем женщины, а пьющие мужчины употребляют алкоголь чаще, в больших количествах и с более высоким риском неблагоприятных последствий, чем пьющие женщины; в ряде стран этот фактор объясняет до 30% гендерного разрыва в ОПЖ). Ценностные объяснения факторов гендерных различий в ОПЖ не ограничены лишь данными кросс-национальных обследований ценностей. Представляется, что в эту же категорию целесообразно отнести объяснения, связанные с доминирующими представлениями о мужественности (маскулинности).
Ретроспектива миграционных связей региона-донора
Authors: Чернышев Константин Анатольевич
Published: May 2021

Данная работа оценивает миграционные связи региона-донора за максимально возможный отрезок времени (1946–2018 гг.) на примере Кировской области – одном из наиболее крупных миграционных доноров в России. Из всех источников данных о территориальной структуре внутренней межрегиональной и международной безвозвратной миграции в России только формы текущего учёта миграции, отражающие передвижение населения по территориям прибытия и выбытия, охватывают изучаемый период полностью. Изменение границ регионов, в разрезе которых осуществлялся учёт прибытий и выбытий, стало существенным ограничением для осуществления ретроспективного анализа миграции. Миграционные связи региона-донора рассматриваются в обмене с 60 укрупнёнными регионами на территории России, границы которых в основном соответствуют границам современных субъектов РФ, и 14 пространствами в ближнем зарубежье. Многократный пересмотр порядка регистрации мигрантов сделал несопоставимыми во времени данные о числе переселений. В результате для ретроспективного анализа межтерриториальных миграционных связей региона-донора приходится прибегать к расчёту коэффициентов результативности миграционного обмена и коэффициентов интенсивности миграционных связей. Это позволяет оценить для каждого периода интенсивность и результативность миграционных связей Кировской области с регионами России и странами бывшего СССР. Наиболее интенсивно жители Кировской области переселялись в соседние республики Коми и Марий Эл, а также в Мурманскую, Свердловскую, Тюменскую, Калининградскую области и на Камчатку. Наименее результативным для региона-донора был обмен с московским и петербургским регионами, Краснодарским краем и Крымом.
Efficacy and safety of endovascular arteriovenous fistula creation with comparison to surgically created fistulas: a systematic review and meta-analysis protocol v1
Authors: Shimamura Yoshinosuke , Kuniyoshi Yasutaka , Yamazaki Hajime , Tsujimoto Yasushi
Published: May 2021

Functional vascular access is the lifeline of hemodialysis patients. The Kidney Disease Outcomes Quality Initiative guideline strongly recommends the creation of arteriovenous fistulas for long-term vascular access. Although arteriovenous fistulas have been created using open surgery, endovascular techniques, the Ellipsys Vascular Access System (Avenu Medical, San Juan Capistrano, California) and the everlinQ endovascular arteriovenous fistula system (TVA Medical, Austin, Texas), were approved by the Food and Drug Administration in 2018. A recent meta-analysis of the endovascular devices reported that the 90-day maturation rate and procedure-related complication rate were 97.5 % and 5.46 %, respectively. Despite the comprehensive search, this meta-analysis did not consider patient-centered outcomes such as patient satisfaction, and it did not directly compare endovascular techniques and surgical arteriovenous creation. To the best of our knowledge, there have been no reviews directly comparing endovascular arteriovenous fistula creation and surgical arteriovenous fistula creation to investigate clinically relevant outcomes, including vascular access maturation, complications, and patient satisfaction. This systematic review and meta-analysis aimed to critically evaluate existing evidence on the clinical efficacy and safety of endovascular arteriovenous fistula creation for the management of chronic kidney disease requiring hemodialysis.
Polarimetry of anisotropic surface layer on glass
Authors: Yampolskiy A. L. , Makarenko O. V.
Published: May 2021

Investigating the Stokes vector of light reflected from the surface of the optical glass, the presence of an anisotropic surface layer was established. The phase difference between radiation p- and s-components is revealed, which varies depending on the angle of incidence. This shows a weak anisotropy. Assuming that the anisotropic layer has an increased refractive index due to its chemical-mechanical treatment, it can be considered as some near-surface weakly guiding gradient burried waveguide. The possibility of coming radiation into such a planar waveguide using a coupling total reflection prism was investigated. The inspection showed a violation of the total internal reflection, unequal for p- and s-polarizations, which confirms the presence of the subsurface layer and its anisotropy. The absorption of radiation, which could be compared with the excitation of modes, is small. This is due to the properties of the prism material. Also, higher order modes are absorbed better. There is no significant angular dependence of the polarization degree of the output beam; however, it is higher in the case of s-polarization.
Probabilistic models of water resources management on urbanized areas
Authors: Kizilova N. M. , Rychak N. L.
Published: May 2021

Gradual global climate change poses new challenges to the mathematical sciences, which are related to forecasting of meteorological conditions, preparing the infrastructure for possible rains, storms, droughts, and other climatic disasters. One of the most common approaches is synthetic regression-probability models, which use the spatio-temporal probability density functions of precipitation level. This approach is applied to the statistics of precipitation in the Kharkiv region, which shows the tendency to a gradual increase in air temperature, high indices of basic water stress, indices of drought and riverside flood threats. Open data on temperature distributions and precipitation were processed using various probability statistics. It is shown that the lognormal distribution most accurately describes the measurement data and allows making more accurate prognoses. Estimates of drought and flood probabilities in Kharkiv region under different scenarios of climate change dynamics have been carried out. The results of the study can be used for management of water resources on urban territories at global climate warming.
Fast pattern matching method for a bitstream
Authors: Zavadskyi I. O.
Published: May 2021

A family of algorithms for fast pattern matching in a bitstream is described. A bitstream is assumed to be stored in a memory and divided into bytes and machine words. The proposed algorithms are based on RZ-family of algorithms for fast pattern matching in a 256-ary text and inherit such their properties as ‘1.5-byte read’, double skip loop, right-to-left text processing as well as a special technique of multiple sliding windows. Beyond that, the new algorithms provide longer average shifts than the best known Binary Faro-Lecroq algorithm and more efficient technique of match checking. Applied to a text close to random, our algorithms outperform all known analogues for all pattern lengths from 20 up to 500.

Authors: Ivanov S. M.
Published: May 2021

The article deals with analytical solution and adaptation to the parameter estimation of the SIR model of the epidemic. By a special replacement of the exponential function by inverse proportionality, the approximate general solution of the SIR model is found. It is spoken in detail about the process of integration of ordinary differential equations of the SIR model. The equality of the sum of the obtained analytical solutions and population size is checked. The obtained solutions are simple and understandable. To parametrically estimate the SIR model, its general solution is adapted to paired linear regressions. The article is of interest for students, graduate students and scientists involved in mathematical epidemiology.
The optimal algorithm for dynamic support of the Voronoi Diagram for a set of points
Authors: Tereshchenko V. N. , Marchenko A. A. , Tereshchenko Y. V. , Tara A. N.
Published: May 2021

The article is devoted to the development of a dynamic data structure for solving proximity problems based on the dynamic Voronoi Diagram. This data structure can be used as the core of the common algorithmic space model for solving a set of visualization and computer modeling problems.

The data structure is based on the strategy of "divide and rule" for Voronoi diagram construction. Similar to the original algorithm, we store a binary tree that represents the Voronoi diagram, but define three new operations: insert, delete, and balance. To ensure the efficiency of operations, it is proposed to use red-black tree. In general, the proposed data structure shows much better results than the original static algorithm. Compared to existing algorithms, this data structure is both simple and efficient.

Authors: Fatikhova L.F. , Sayfutdiyarova E.F.
Published: May 2021

The article is devoted to the problem of studying mechanisms of responding to danger and recognizing emotional states of participants in dangerous situations in the process of regulating safe behavior in students of adolescent and youthful age with intact and impaired intelligence. It was assumed that there are differences in the emotional component structure of psychological safety among students, due to age-related characteristics (adolescence and youth) and the presence (absence) of intellectual disabilities in these students. The study involved students of adolescent and youthful age with intact and impaired intelligence. To achieve the goal of the study, the authors used a questionnaire test by V.G. Maralov to identify types of attitude towards danger, the methodology “Emotional attitude of adolescents to dangerous situations”, and the methodology “Adolescents in dangerous situations”, designed to study the ability to recognize emotional states of people in dangerous situations. Through correlation analysis, the authors revealed the relationships between the elements of the emotional component in the students' perception of a dangerous situation, namely, between the parameters of emotional attitude to dangerous situations, and the ability to recognize the emotional states of participants in dangerous situation. Such relationships are more represented in adolescents with impaired intelligence than in their peers without intellectual disabilities. The results of the study allow us to state the differences in the mechanisms of formation of psychological safety in students of adolescent and youthful age with impaired and intact intelligence. The data obtained can be used in the development of programs for formation of psychological mechanisms that allow students to avoid dangerous situations.
The Influence of the Type of Educational Environment on Preschool Children's Mental Development
Authors: Shishova E.O.
Published: May 2021

The article is devoted to the study of the developing potential of educational environments and their impact on the formation of personality in the modern educational space. Based on the theoretical and methodological analysis of the types of educational environment, it is concluded that in the structural plan the educational environment of preschool childhood is a system of interconnected components, the main components include object-spatial, socio-psychological, cognitive-active, communicative and subjective components. Based on cluster analysis, four distinctive modern types of educational environment with various capabilities are identified and the author's typology of educational environments in the system of preschool education is proposed, depending on the severity of each component. The tendencies to the conjugation of the quality parameters of the educational environment (according to the ECERS-R scales) and the personal characteristics of children, as well as significant differences in the subjective characteristics and initiative of preschoolers in different learning environments have been identified. The efficiency and feasibility of using the cluster analysis method in the study of the qualitative characteristics of the educational environment and their developing potential is shown. Empirical data were obtained on the basis of 16 preschool educational organizations in the Republic of Tatarstan, on a sample of subjects in 876 people (50 teachers, 413 preschool children and 413 parents (mothers) of preschool children).

Analyzing and Forecasting of Electricity Consumption by Integration of Autoregressive Integrated Moving Average Model with Neural Network on Smart Meter Data
Authors: Et. al. M. Suresh,
Published: May 2021

Smart metering is a recently developed research area over the globe and it appears to be a remedy for increasing prices of electricity. Electricity consumption forecasting is an essential process in offering intelligence to smart girds. Rapid and precise forecasting allows a utility provider to plan the resources and also to take control actions to balance the electricity supply and demand. The customers will advantage from the metering solutions by a greater understanding of their own energy utilization and forthcoming projections, allowing them to effectively manage the cost of their consumption. In this view, this paper presents an Integration of Autoregressive Integrated Moving Average (ARIMA) Model with Neural Network (NN) for Electricity Consumption Forecasting using Smart Meter Data. As the time series data often does not hold linear as well as nonlinear patterns, ARIMA or NN models are not enough to model and predict the time series data. The ARIMA-NN model will be trained using the data and generates a model. Afterward, the generated model can be utilized to predict the electricity consumption by the application of new building data. The proposed ARIMA-NN model is evaluated and the simulation outcome strongly pointed out its superior performance over the compared methods. The presented model has obtained effective testing performance with the MAPE of 25.53, an accuracy of 48.38, and MSE of 0.21.
The mild weapon of the crown: making the constitutional value of pardon with public opinion and the interference of the moderating power over the judiciary (Brazil, 1823-1889)
Authors: Barrêtto de Almeida Costa Arthur
Published: May 2021

Resumo: A graça é um instrumento ambivalente, com raízes tanto no direito penal como no constitucional. O objetivo deste trabalho é compreender a dimensão constitucional da clemência real no Brasil império. Analisei duas de suas principais expressões. Em primeiro lugar, tratei da opinião pública, que foi um dos principais elementos da teoria constitucional do século XIX e investiguei como a sociedade civil interagia com os comportamentos do Estado em relação ao perdão. Os principais aspectos abordados foram discussões sobre a legitimidade da própria existência da graça e a pertinência de perdões específicos. Em segundo lugar, tentei entender como o monarca interferiu em certas partes do direito brasileiro para conduzi-lo a um melhor desempenho. A principal área analisada foi o funcionamento do júri. O lugar especial do perdão na paisagem constitucional brasileira do século XIX só pode ser efetivamente compreendido com referência à particular separação de poderes do Brasil oitocentista, que concedia ao imperador um poder especial: o moderador. As principais conclusões foram que a opinião pública, expressa principalmente na imprensa e no parlamento, teve um papel importante tanto na formação do perdão quanto na sua legitimação; e que o imperador, através do poder moderador, usou o perdão para lidar com alguns maus funcionamentos da legislação brasileira.Palavras-chave: graça, misericórdia real, poder moderador, constitucionalismo oitocentista, Constituição de 1824.Abstract: Pardon is an ambivalent tool, with roots both in criminal and constitutional law. This paper aims to understand the constitutional characteristics of royal clemency in imperial Brazil. I analyzed two of these features that can be deemed more prominent. First, I looked into the public opinion, which was one of the crucial mechanisms of 19th-century constitutional theory and investigated how civil society interacted with the state's impulses regarding pardon. The main aspects I dealt with were discussions on the legitimacy of the very existence of royal mercy and the pertinence of specific pardons. Second, I investigated how the monarch interfered in certain parts of Brazilian legislation to push it into a better performance. The main aspect handled with recourse to pardon was the functioning of the jury. The special place of pardon in Brazilian 19th-century constitutional landscape can only be understood taking into consideration its connection with the particular Brazilian separation of powers, which granted the emperor a unique moderating power. The main conclusions were that the public opinion, expressed mainly in the press and the parliament, had an important role in both shaping pardon and legitimizing it; and that the emperor, through the moderating power, used pardon to cope with some malfunctioning of Brazilian legislation.Keywords: Pardon, royal mercy, moderating power, 19th-century constitutionalism, 1824 Constitution.
Who has Shown Solidarity With Whom in the EU During the COVID-19 Pandemic of 2020? Lessons for Teaching Solidarity to Students
Authors: Wallascheck Stefan
Published: May 2021

This paper analyses the solidarity relations among European Union (EU) member states in the first phase of the COVID-19 pandemic of 2020. The pandemic affected European countries differently and also questioned the problem-solving capacity of the EU in such an unprecedented crisis. Based on the European solidarity tracker data collected by the European Council for Foreign Relations, I reconstruct the solidarity relations between the member states. I demonstrate that the EU receives most of the solidarity attention from almost all member states. Moreover, publicly declaring solidarity and showing actions of solidarity are closely linked to each other in this time period. Experiencing and observing the pandemic across Europe has crucial implications on how solidarity as relation can be taught, included in future curricula, and discussed between teachers and students.

Esta investigación tuvo como objetivo analizar evidencias psicométricas de la Escala de Satisfacción con la Vida (SWLS) en población adulta Lima Metropolitana, 2020. Se evaluó a 314 personas, entre ellos 166 mujeres y 148 hombres con un rango de edad entre 18 a 59 años. Asimismo, se aplicó el tipo de muestreo no probabilístico por conveniencia, donde las personas participaron de manera voluntaria. Por otro lado, se emplearon los siguientes instrumentos PANSI, SHS, UCLA para correlacionarlos con la satisfacción. Entre los resultados se evidenció correlación con diferentes variables; además, la varianza total fue de 70% del instrumento, los índices de ajustes (TLI= .997, CFI= .998, RMSEA= .021 y SRMR= .021) indicaron la unidimensional de la SWLS; por consiguiente, los coeficientes (α= .79 y ω= .80) demuestran la confiabilidad de la escala SWLS. En conclusión, el instrumento posee adecuadas evidencias psicométricas para su uso en población adulta de Lima Metropolitana.

Este trabajo es consecuencia de la interrogante que los autores se hacen frente una problemática creciente, que está tomando cada vez más adeptos; las conductas autolesivas o autodestructivas sin intención suicida, esta práctica consiste en causarse daño al propio cuerpo de forma deliberada, particularmente mediante cortes, quemaduras, pellizcos, rasguños, abuso de drogas y de otras sustancias, incluso de alimentos, puede tener, según manifiestan, diversas intenciones, en las que no está considerada el suicidio. Estas conductas, son producto de algunas anomalías en la percepción principalmente de los adolescentes, en las que, el individuo busca esconder un sentimiento de incomodidad, de dolor emocional, el cual aliviará por un instante esa sensación que puede estar sintiendo, pero que al ser reiterativo puede desencadenar en una gran depresión y un probable suicidio. Se ponen en evidencia, factores condicionantes, factores de riesgo, y algunas estrategias que apuntan hacia la necesidad de promoción de la salud mental de manera urgente, principalmente en los jóvenes.

La presente investigación tuvo como objetivo identificar las evidencias métricas de la escala de miedo percibido relacionado con la pandemia covid-19 en adultos de Tacna, 2020. La investigación fue de tipo instrumental, se realizó un muestreo no probabilístico por conveniencia, participaron 157 adultos de la ciudad de Tacna, cuya edad oscilaba entre los 20 a 59 años, siendo el 68,2% de sexo femenino y el 31,85% de sexo masculino. Se utilizó la escala de miedo relacionado a la pandemia covid-19 (FCV-19S) de Ahorsu et al. (2020) y la recolección de información fue de modo virtual. Los resultados indican que la escala de miedo en su propuesta original es unidimensional pero que al momento de traducirla al español es conveniente tratarla como bidimensional debido a que la primera no presenta buenos índices de ajuste, en cambio la nueva propuesta sí los presenta de modo tal que se concluye que tiene buena validez de constructo (X2/gl = 3.286; CFI=0.943; GFI=0.926; TLI=0.907; SRMR=0.0504). Esta propuesta fue elegida (AIC=72.712) al compararla con otras dos que no alcanzaron los criterios óptimos. El índice de ajuste de la propuesta de bifactorial presentó evidencias de validez de constructo y con índices del modelo bifactor adecuados (X2/gl=1.713, CFI=0.992, GFI=0.981, TLI=0.971, SRMR=0.0260; wh=0.703; Hng=0.955); aunque el ECV=0.521 y PUC=0.571 fueron bajos. Sin embargo, debería ser puesta a prueba en futuras investigaciones. La escala presenta un alfa ordinal de 0.856 y un coeficiente omega = 0.836 demostrando que el instrumento posee alta confiabilidad. El estudio reporta que la versión en español del FCV-19S aplicada a población de Tacna, Perú, demostró un modelo bifactor con propiedades psicométricas adecuadas. Por lo tanto, se recomienda utilizarlo dentro de la población general.

El presente trabajo de investigación, “Programa “Decido mi futuro” en la madurez vocacional, en estudiantes víctimas de marginación social del 4to grado del ciclo avanzado del CEBA Herman Busse de la Guerra, 2095, 2018.”, buscó conocer los efectos que produce la intervención de un plan de orientación vocacional, conformado por talleres fundamentados en principios psicopedagógicos, y cuya aplicación didáctica está en función de los objetivos y principios de la propuesta. La investigación fue de tipo aplicada, de diseño pre experimental. El grupo de estudio estuvo conformado por 84 estudiantes, distribuidos en 42 en el grupo experimental y 42 en el grupo control.  Se aplicó el pretest utilizando el cuestionario de madurez emocional donde se obtuvieron puntajes en dimensión madurez emocional (t=1.21, p=0.23), en la dimensión planificación (t = 0.62, p = 0.54), la dimensión exploración (t = 1.11, p = 0.27), la dimensión información (t = 1.11, p = 0.27) y por último en la dimensión toma de decisiones (U = 844, p = 0.73) evidenciándose que no existen diferencias estadísticamente significativas en el pretest en el grupo experimental y grupo control. Los resultados del postest nos muestran que después de haber aplicado el programa vocacional los grupos control y experimental si se evidenciaron diferencias significativas en sus cinco dimensiones: En madurez emocional (t = 9.28, p = 0.00), en la dimensión planificación (t = 0.62, p = .001), en la dimensión exploración (t = 4.865, p = 0.000), en la dimensión información (U = 314.5, p = 0.000), y en la dimensión toma de decisiones (U = 71.00, p = 0.000).  El estudio comprobó la eficacia del programa “Decido mi futuro”.
Escala de estrategias de aprendizaje ACRA: Adaptación psicométrica en estudiantes universitarios peruanos
Authors: Gonzales Córdova Grecia Libertad
Published: May 2021

El estudio tuvo como finalidad adaptar la Escala de Estrategias de Aprendizaje (ACRA) de Román y Gallego (1994) en los estudiantes de una Universidad Privada-San Juan de Lurigancho. El diseño fue no experimental de corte transversal y de tipo psicométrico. Participaron 400 estudiantes seleccionados mediante un muestreo probabilístico, pues se calculó el tamaño de la muestra al 95% de intervalo de confianza y fueron distribuidos proporcionalmente de acuerdo a su carrera profesional. En cuanto a los procedimientos, se realizó el análisis de ítems, para luego someterlos al criterio de cinco jueces expertos, los que verificaron la validez de contenido de la prueba. Luego, se realizó el análisis de componentes principales, donde el KMO mostró valores desde 0,86 hasta 0,91 y el test de esfericidad de Bartlet fue menor a 0,05, lo que permitió verificar la validez de constructo, hallando porcentajes de varianza entre 52 % y 64 %. Además, la fiabilidad se estableció por consistencia interna a través del índice Alfa de Cronbach y la fórmula de Spearman-Brown, obteniendo valores para cada sub-escala, adquisición, codificación, recuperación de la información y apoyo al procesamiento, desde 0,71 hasta 0,92. Por lo tanto, es estudio concluye, que existen evidencias suficientes de validez y confiabilidad del instrumento para su aplicación. Adicionalmente, se elaboraron normas percentiles que serán de utilidad para identificar las estrategias de aprendizaje predominantes en la población de estudio y próximas investigaciones que permitan un mejor conocimiento de esta variable.
