The Survival Force of Literature
Authors: Kowalska-Nadolna Urszula
Published: February 2021

The following review article brings a presentation of the published in 2018 encyclopaedia of Czech literary samizdat. The analysed publication consists of two parts – a comprehensive introduction discussing the question of independent literary culture in Czechoslovakia under communist regime pressure and an entry section with more than 300 entries about Czech independent self-publishing activities. The presentation of the following book provokes the need to re-examine the phenomenon of Czech samizdat, reflecting on its chronological framework, definition, meaning and role in creating and keeping alive an independent culture in the era of domination of the communist regime (1948–1989).

Authors: Mirocha Piotr
Published: February 2021

The paper presents the activity of a new Serbian journal “Novorečje” dedicated exclusively to neologisms in language. Analyses disseminated in this periodical are discussed in the context of the approaches to new vocabulary elaborated in the framework of Serbian linguistics. Parallels and divergences with respect to Polish linguistic tradition are also presented. Finally, the paper tries to summarise main research tendencies represented by the authors publishing in the journal “Novorečje”: analyses of new feminatives, discussions on derivative mechanisms, neosemantisms, semantic drives, phraseological innovations, lexemes denoting new phenomena, as well as methodological problems.
Czech Samizdat Archives – the Past and the Present
Authors: Přibáňová Alena
Published: February 2021

In the former Czechoslovakia, samizdat was not limited just to the dissident community: the big “publishing houses” like Vaculík’s Petlice soon became a model for many local followers. Under communism, they naturally made effort to keep their activities secret; after 1989 vast majority of them did not find a reason to claim credit for their work and their production remained buried in their personal archives. Therefore, the lexicographic and bibliographic research in Czech samizdat faced a lengthy problem: while a representative part of the (mostly Prague) dissident publications had been smuggled out of the CSSR and collected in specialized archives in Scheinfeld (Germany) in the 1980s, it took quite a time to identify the local samizdat publishers and get access to their production.
The resolution property via Azumaya algebras
Authors: Mathur Siddharth
Published: February 2021

Using formal-local methods, we prove that a separated and normal tame Artin surface has the resolution property. By proving that normal tame Artin stacks can be rigidified, we ultimately reduce our analysis to establishing the existence of Azumaya algebras. Our construction passes through the case of tame Artin gerbes, tame Artin curves, and algebraic space surfaces, each of which we establish independently.

Published: February 2021

Objective: to analyze the satisfaction of family members with the social support received during the care of children exposed to human immunodeficiency virus. Methods: cross-sectional study with 87 relatives of these children, in a university hospital. The Satisfaction with Social Support Scale was used. Sociodemographic and clinical variables were analyzed using the Lilliefors, Kruskal-Wallis and Mann-Whitney tests. Results: the participants, mostly mothers, showed high satisfaction with the total social support (57 out of 75 points). The average indicated that the satisfaction was high for the support received from the family (80.46), followed by that provided by friendships (72.86) and intimacy (63.36) and low for social activities (55.65). The group classified with income up to R$879.00 presented less satisfaction with social support (average=50,83) if compared with the group of income superior to R$879.00 (average=58,78) (p=0,014). Conclusion: the satisfaction with the social support of the relatives is high and influenced by income.
Profesjonalizm nauczyciela a kultura praw dziecka w szkole
Authors:   Akademia Pomorska w Słupsku, Babicka-Wirkus Anna
Published: February 2021

Artykuł porusza problematykę urzeczywistniania kultury praw dziecka w szkole i roli, jaką w tym procesie odgrywa nauczyciel profesjonalista. Praktykowanie tej kultury w codzienności szkoły jest zadaniem wymagającym posiadania przez nauczyciela nie tylko gruntownej wiedzy na temat praw dziecka i praw człowieka, ale także akceptacji tych idei oraz stworzenia możliwości doświadczania i upominania się o nie w szkole. Akademicki i potoczny dyskurs na temat profesjonalizmu nauczyciela pomija lub marginalnie traktuje ten wymiar, co skutkuje niskim poziomem praktykowania kultury praw dziecka w szkołach. Stan ten ma znaczenie również dla jakości przygotowania obywateli do życia w demokratycznym społeczeństwie obywatelskim, dla którego podstawą są prawa człowieka i prawa dziecka.

Zaprezentowany tekst przybliża ważną współczesną koncepcję – „model cebuli” Freda Korthagena. Wskazuje jej ugruntowanie w opracowaniach naukowych oraz adekwatność do dyskusji nad zmianami edukacyjnymi i rozważaniami dotyczącymi profesjonalizmu nauczycieli. Autorka wykorzystuje model również do opisu profilu nauczycieli akademickich, wśród których prowadziła wywiady. W efekcie tych zabiegów ukazuje harmonię pomiędzy warstwami tytułowej „cebuli” i drogę „przepływu” nauczycielskiej „jakości z wnętrza” oraz podkreśla rolę wielopoziomowego kształcenia nauczycieli.
Egzystencjał personalny nauczyciela – nowe podejście w dydaktyce ogólnej
Authors:   Uniwersytet Kardynała Stefana Wyszyńskiego w Warszawie, Paluch Michał
Published: February 2021

W artykule przedstawiona jest propozycja wykorzystania podstawowego terminu antropologii filozoficznej, jakim jest Osoba (osobotwórczość), w celu wydostania się z ciążącej na polskiej dydaktyce ogólnej bezosobowej epistemologii marksistowsko-leninowskiej. Aby zabieg ten uczynić czytelnym, autor podjął się krytycznego spojrzenia na naukową twórczość Wincentego Okonia (1914–2011), uchodzącego za niepodważalny autorytet w dziejach polskiej powojennej dydaktyki. Krytyka ta odbywa się na tle wyłaniającej się istoty Człowieka, przedstawionej przez Karola Wojtyłę (1920–2005), w dziele znanym jako Osoba i czyn (1969). Artykuł obfituje tym samym w język filozoficzny i wynikające z niego neologizmy, dawno niestosowane w polskim dyskursie dydaktycznym. Do takich autorskich pojęć należy „egzystencjał personalny”, akcentujący potrzebę wyodrębnienia nauczania jako sposobu Bycia od innych przejawów ludzkiej egzystencji. Na tej podstawie ukazane zostały profile egzystencjalne wykładowców akademickich, wyprowadzone teoretycznie z personalizmu. Wyróżniono trzy egzystencjały personalne, będące wykładnią poziomów uczestnictwa nauczyciela we własnym wykładzie: (1) dydaktyczny (gr. didáskō, nauczam); (2) heurystyczny (gr. heuriskō, odnajduję, poszukując); (3) ginetyczny (gr. ginōskō, poznaję przez doznanie samego siebie). Na każdy z trzech egzystencjałów przypada określony typ tożsamości: (1) biernego wykonawcy czynności, (2) aktywnego twórcy dzieła oraz (3) przeżywającego relację z sobą samym i innymi sprawcę czynu nauczania. Artykuł ma charakter propedeutyczny. Pełny opis wybranych cech i wskaźników każdego z profili oraz ich pogłębione założenia teoretyczne i metodologiczne stanowią główną treść rozprawy doktorskiej i przygotowywanej na jej podstawie osobnej publikacji.

Published: February 2021

Thermal detectors find a significant niche in the market of modern sensors. Bi2T3 and PbTe semiconductors are effective thermoelectrics and excellent candidates for different applications. In the present work, a technology for fabrication of p-Bi0.5Sb1.5Te3 and n-PbTe films with the high thermoelectric efficiency on thin flexible polyimide substrate has been developed. The preparation of films was performed by flash evaporation method. The high sensitivity of the devices is due to the high Seebeck coefficient of 200 mV/K and reduction of thermal conductivity of thin thermoelectric film from the bulk value. The devices operate in the Johnson-Nyquist noise limit of the thermocouple. The performance enables fast and sensitive detection of low levels of thermal power and infrared radiation at room temperature.

Published: February 2021

Purpose: to analyze the features of the participation tactics of the world's leading athletes in the system of women's wrestling competitions during the Olympic cycle of 2013-2016. Materials and methods. Theoretical analysis, documentary method, generalization of literature and Internet data allowed to identify the problematic field of tactics in martial arts, to summarize current trends in Olympic martial arts, to identify commonalities and differences in the systems of Olympic selection. Analysis of the competitive performance of the world's leading women-athletes who took first-third places at the Games XXXI of Olympiad 2016 in Rio de Janeiro in wrestling competitions (a total of 24 athletes – four in six weight categories). The results were processed using Microsoft Excel. Results: features of the competition system in women's wrestling were revealed. It is characterized by the presence of a large number of tournaments of different categories, a multi-stage system of Olympic selection, the discrepancy between the number of weight categories represented at the World Championships and the Olympic Games. During the first-third seasons of the 2013-2016 Olympic cycle, most of the world's leading athletes gradually increased their competitive practice from 3.96 to 5.13 tournaments per year, while in the fourth, they reduced it to 4.29 tournaments. Conclusions. The participation tactics of the world's leading athletes in the system of women's wrestling competitions during the season and the four-year cycle has differences depending on the dynamics of sports results. There are four types of tactics: retention of leadership, gradual increase of results, combined (during the first or second seasons - gradual increase of results, in the third-fourth - retention of leadership), return of leadership. Six types of tactics for choosing a weight category have been identified. They were used by different sportsmen within a season or the whole Olympic cycle. Keywords: competitions, Olympic Games, Olympic cycle, calendar, season, tactics, results

Authors: Romanenko V. , Tropin Y. , Veretelnikova N. , Panov P.
Published: February 2021

Purpose: to investigate the dynamics of changes in the selection reaction of combatants after performing exercises with tennis balls. Materials and methods. The study used the following methods: analysis of scientific and methodological information, Internet sources and generalization of advanced practical experience, psychophysiological research methods, methods of mathematical statistics. The study involved 21 combatants, age 19,7±1,12 years. Of these: 73 % are candidates for Master of Sports of Ukraine, 27 % are Master of Sports of Ukraine. The selection reaction was assessed using the Reaction RCHR test, developed at the Department of Martial Arts of the KSAPC for tablet personal computers. A feature of the proposed test is the ability to simultaneously obtain both the selection reaction values and the heart rate (heart rate) value using a chest heart rate sensor (Bluetooth 4.0). The test result included the following indicators: the average value of the choice reaction and heart rate for the test, the average values of the choice reaction and heart rate at the first, second and third stages (10 attempts in each stage). To study the dynamics of changes in the manifestation of the choice reaction, the participants were asked to perform the task in the following sequence: 1. Test to determine the choice reaction; 2. Exercises with tennis balls (2 minutes) 3. Test to determine the reaction of choice. Results: of the study showed that, on average, the result of passing the test after doing exercises with tennis balls was improved: the first stage – by 11 %, the second stage – by 7 %, the third stage – by 6 %. The heart rate values at the end of the test are less than at the beginning by 4,9 beats/min (at the first test run) and by 16,7 beats/min (at the second test run). This reaction of the cardiovascular system is natural and is due to the recovery process of the studied combatants after the load. Conclusions. It was found that the performance of exercises with tennis balls has a positive effect on the manifestation of the choice reaction; this is the basis for recommending these exercises to activate the mechanisms of control of specialized movements of combatants. The efficiency and convenience of the Reaction RCHR test allows it to be used as an express control of the athlete's functional state.

In this paper, a new solar distiller floating on ocean with cylindrical surface concentrator and vertical gap evaporator is proposed for solving the problem of freshwater shortage in islands. When the distiller is floating on ocean, the vertical gap will fill with seawater automatically due to the siphon effect of hydrophilic material. Then the seawater is heated to generate vapor when the incidence sunlight is concentrated to the gap by the cylindrical concentrator. Finally, the vapor reaches the arched transparent glass at the top of the device and condenses to produce fresh water. Optical simulation for the solar distiller is carried out to find the optimal radius of the cylindrical concentrator and the height of the vertical gap. The results indicate that when the radius and height is 6 cm and 5 cm respectively, 80% of the sunlight number within the incidence angle of 45° can be captured by the seawater in the vertical gap. The annual optical performance of the distiller is analyzed for the region within 17° north latitude. As the result, the device placed in east-west direction possesses superior performance. There are more than 10 working hours and 5 working hours in which the reception rate is more than 80% in summer solstice and winter solstice respectively. In autumnal equinox, there are more than 11 working hours with the reception rate exceeding 90%. Energy balance analysis for the whole system is carried out and the stable evaporation rate per unit solar collector area increases gently from 0.12 g/ (m2‧s) to 0.65 g/(m2‧s) when the solar irradiance increases from 500 W/m2 to 1000 W/m2.
Price Setting Dynamics Modeling on the One Product Market Under Uncertainty
Authors: Bizyanov Yevgeny , Podgornaya Nataliia
Published: February 2021

This article discusses various options for studying the classic Evans model for assessing the dynamics of price setting for a new good in the conditions of uncertainty in the behavior of the market and the producer. The Evans model with fuzzy coefficients for supply and demand curves was used for modeling. As a result, it was found that when the level of opportunity for the parameters of the supply and demand curves change, the ranges of the equilibrium price will change, as well as the time of its establishment – the achievement of the equilibrium level. In addition, modeling was produced taking into account the lag in the supply from around the delay in the receipt of information on sales. The introduction of a fuzzy lag into the Evans model at a certain ratio of supply and demand parameters leads to significant price fluctuations, which can upset the equilibrium in the market, as well as lead to significant fluctuations in profit for the producer. The implementation of the Evans model with a lag in the proposal was carried out using the Simulink program of the Matlab. As a result of modeling, the dependences of the time for establishing the equilibrium price and the elevation of the price amplitude over its equilibrium value were obtained as a function of the opportunity’s level.
Economic Entities in the Context of Technological Modernization of Economy: Priority Trends Taking into Account Digital Transformation
Authors: Shkalenko Anna , Tymchuk Yulia
Published: February 2021

The basis of this study is the use of elements of an innovative methodology of post-institutional analysis based on the interdisciplinary synthesis, which involves overcoming the monodimensionality, dichotomization and dogmatism of many concepts of orthodox neo-institutionalism. The main idea of this study is to apply an interdisciplinary approach to study the impact of technological modernization on economic entities and identify priority trends taking into account digital transformation of public relations. The assessment of the current problems under study and the conceptual framework of the study were carried out on the basis of studying and rethinking the results of numerous works by European and Russian scientists, as well as the legislation of the Russian Federation. The regulatory framework covers current domestic legislation in the field of civil, business and tax law, which regulates innovative activities. As a result of the conducted research, it is established that innovative activity is managed by a large number of regulations of various industry affiliation, which do not have any systemic connection with each other. The existing terminological intricacy is revealed in innovation legislation. The current legislation, including at the level of the constituent entities of the Russian Federation, does not set the criteria and the indicators of an innovative organization. This serves as a factor that both complicates obtaining state support and hinders the wider introduction of innovations. The mechanisms of stimulating innovative activity provided by the tax legislation are investigated, and their effectiveness is also evaluated. The article proves the need for adoption of a special Federal Law aimed at regulating innovative legal relations. The need to improve the tax legislation is justified in terms of creating a special tax regime for subjects of innovative activity. It is proposed to expand the measures of state support for innovation activity within the subjects in the Russian Federation by introducing the institute of innovation voucher. The role of responsible innovations for sustainable business development in the period of digital transformation of society is defined.
Development of Forecasting Models Suitable for Metal Trading Companies
Authors: Paytyan Karen
Published: February 2021

The volume of world metal consumption is one of the main indicators of the state of economy as a whole. This is explained by the fact that such an industry as construction presents a great demand for these products. At the same time, the volume of construction is growing along with the economy growth, because a healthy market attracts more investment. Therefore, the state of the global metal market is one of the indicators of the state of the global economy as a whole, and the challenges facing this industry are relevant for the entire world market. One of them is forecasting metal prices to make right business decisions. The article presents a practical task that shows the need for forecasting. At the next step, the author developed a criterion for the quality of forecasting, if satisfied, we can talk about the applicability of the model in practice. On a randomly selected time interval, the quality of common statistical forecasting models, such as the pair regression equation and linear models, is analyzed. New models have also been developed that are based both on a technical analysis of exchange quotations of metal prices and on a fundamental one. At the final step, the results of all the models presented in the work were compared with the criterion of applicability developed in practice by the author and the most promising of them were selected.
Honoring Languages: Review of Creole Composition: Academic Writing in the Anglophone Caribbean
Authors: Baird Pauline
Published: February 2021

In traditional Caribbean villages, the bell crier made important announcements from street to street. People listened and carried the news further. Like the proverbial bell crier, Milson-Whyte, Oenbring, and Jaquette, along with fourteen contributors announced “We are here. And we doin’ dis—‘write [ing] our way in” to academic spaces (Creole Composition, 2019, p. x). Creole Composition provides current perspectives on post-secondary composition pedagogy, academic literacies, and research across multiple academic disciplines. Indeed, this intersectionality addresses Browne’s (2013) argument that Caribbean vernacular orientations and practices fly beneath the radar of the discipline of Rhetoric and Composition. Caribbean institutions of higher learning must embrace Caribbean students’ creole-influenced languages.

Published: February 2021

Compreender a consolidação das Diretrizes Curriculares Nacionais (DCN) demanda contextualizar a realidade de cada instituição. Sua implantação pressupõe (re) orientação do processo de formação na Saúde, com integração entre Projeto Pedagógico do Curso (PPC), Sistema Único de Saúde (SUS) e envolvimento docente. Para captar a percepção docente sobre o alinhamento entre PPC e DCN, realizou-se estudo exploratório com metodologia qualitativa e os docentes respondendo a um questionário. Utilizou-se análise de conteúdo para construção de categorias temáticas. Os docentes de uma escola reconhecem que o PPC não está alinhado às DCN. Revelam trabalho docente determinado por perfil profissional e pessoal. Em outra escola, cuja reforma curricular já adota metodologia de ensino-aprendizagem ativa, os docentes se sentem apropriados às DCN. Concluímos, portanto, que as mudanças no PPC são processos que demandam tempo, dedicação e comunicação, ou seja, maior mudança na instituição de ensino.
Preconditions for a General-Purpose Central Bank Digital Currency
Authors: Cheng Jess , Lawson Angela N , Wong Paul
Published: February 2021

Over the last few years, interest in the potential issuance of a general-purpose central bank digital currency (CBDC) has increased. Introducing and operating a CBDC would require actions by many stakeholders and not just the central bank. In view of the far-reaching implications of introducing a new form of money to the public, the decision cannot be taken lightly. This paper outlines foundational preconditions and proposes areas of work that may help achieve them prior to the possible implementation of a potential future general-purpose CBDC in the United States. These foundational preconditions include clear policy objectives, broad stakeholder support, a strong legal framework, robust technology, and readiness for market acceptance and adoption.
Life history traits of five ground beetle (Coleoptera: Carabidae) species common in Honshu Island, Japan
Authors: Shibuya Sonomi , Kiritani Keizi , Fukuda Kenji
Published: February 2021

Ground beetles have been used as bioindicators for monitoring environmental changes. However, to interpret monitoring results, we need further information on their life history traits. We selected Harpalus griseus, H. eous, H. tridens, Synuchus cycloderus and Carabus procerulus, species common in Honshu Island, Japan. We examined their hind wings, flight muscles, gut contents and ovarian eggs to understand their flight activity, feeding traits and reproductive strategies. The three Harpalus species showed wing length / body length ratios (W/B) of 0.88 - 0.99. In H. tridens, the proportion of individuals with flight muscles and caught in aerial traps was lower than in the other two. S. cycloderus was macropterous with a W/B ratio of 0.75, but no individuals were caught in aerial traps, and none possessed flight muscles. C. procerulus was brachypterous. The three Harpalus species fed mainly on seeds and partly on arthropods. S. cycloderus was a generalist predator. Gut contents of C. procerulus consisted of amorphous fluid, suggesting extra-oral digestion. Egg type was categorized by the number and size of ovarian eggs. S. cycloderus had many-small eggs, while the other four had few but large eggs.

RECOVERY OF ABSOLUTE PERMEABILITY OF HYDROCARBON DEPOSITS WITH SECONDARY POROSITY–PERMEABILITY PROPERTIES USING WAVELET TRANSFORMS
Authors:   Tomsk Polytechnic University (Tomsk, Russian Federation), A.A. Orlov , A.S. Russkikh ,   Tyumen Branch of SurgutNIPIneft of Surgutneftegas (Tyumen, Russian Federation)
Published: February 2021

Due to depletion of hydrocarbon reserves in “traditional” porous reservoirs, it becomes necessary to study and evaluate the prospects for the development of reservoirs with secondary porosity–permeability properties (SPP). Permeability in reservoirs with SPP is described in a hydrodynamic simulator using a dualenvironment model represented as a set of porous blocks (matrix) separated by a system. One of the most important hydrodynamic model (HDM) parameters is the absolute reservoir permeability coefficient. However, recovery of the latter for reservoirs with SPP by standard methods is impossible. The purpose of this research is to restore a cube of the absolute permeability of a hydrocarbon reservoir with SPP using the wavelet transform method which accounts for the structure, to reproduce well dynamics in the HDM, and to analyze the applicability of the obtained maps when predicting distribution of productive zones. Wavelet-decomposition maps give a detailed description of the structural surface amplitude corresponding to the geological representation: the most productive zones are those with structural failures such as bending or dome. The downhole historical matching for bottom-hole pressure measurements and the dynamics of the work implemented using the wavelet transform method are performed in accordance with regulation requirements, which allow one to use a hydrodynamic model in the calculation of predictive options.
NUMERICAL SIMULATION OF UNSTABLE MODES FOR A SAFETY VALVE

When designing pressure regulators, one needs to have a complete understanding of gasdynamic processes. The numerical algorithm for three-dimensional gas-dynamic modeling of a full cycle of spring safety valve operation is proposed, which allows one to significantly reduce the computing time. Grid reconfiguration during CFD modeling is provided by interpolation procedure using previously calculated grids. Calculations show that gas-dynamic numerical simulation should account for a three-dimensional structure of the unsteady flow and the motion of the disc. These factors are taken into account when calculating full cycle of the valve on a coarse grid with the use of correction functions for the force and flow characteristics of the valve. The correction functions are calculated by the false transient method in the three-dimensional formulation. Cyclograms of the valve operation demonstrate satisfactory agreement of the experimental and numerical simulation results. The agreement in the variation of gas-dynamic forces with time is observed, except for the transitional regime before the valve starts to close. In the main work area, the calculated values of the reduced force belong to a confidence interval.
Противоречивость толерантности в контексте этики автономии и этики сообщества
Authors: Сычев О.А. , Протасова Н.
Published: February 2021

В статье представлены результаты анализа толерантности в ее взаимосвязях с моралью на основе теории моральных оснований Дж. Хайдта. Обзор литературы показал, что общим для многих исследователей является признание противоречивости толерантности, в том числе в моральном аспекте. С точки зрения теории моральных оснований такая противоречивость может быть следствием того, что толерантность хорошо согласуется с этикой автономии, включающей нормы заботы и справедливости, но при этом противоречит этике сообщества, включающей нормы лояльности группе, уважения и чистоты. Подобное противоречие должно заметно проявляться, когда речь идет о толерантности по отношению к потенциально опасным группам. Для проверки этой гипотезы было проведено исследование с участием 202 студентов (в возрасте от 18 до 46 лет, 36% мужчин), ответивших на вопросы методики многофакторного исследования толерантности (МИТ) и опросника моральных оснований (MFQ). С помощью эксплораторного факторного анализа шкал МИТ были выделены два типа объектов толерантности: «уязвимые» группы (старшие, маргиналы, больные, противоположный пол) и «опасные» группы (религиозные, национальные, чужаки, преступники). Для проверки гипотезы о противоречивых отношениях толерантности с этикой автономии и этикой сообщества была построена структурная модель, в которой этика автономии была прямо связана с толерантным отношением к уязвимым и опасным группам, в то время как этика сообщества связана с интолерантностью в отношении опасных групп. Хорошая согласованность этой модели с данными позволяет сделать вывод о том, что этика автономии поддерживает толерантность по отношению к любым группам, в то время как этика сообщества противоречит толерантному отношению к опасным группам. Разнонаправленные связи толерантности с моральными основаниями раскрывают противоречивость толерантности в контексте этики автономии и этики сообщества.
Design in Planning: Reintegration through Shifting Values
Authors: Rivera Danielle Zoe
Published: February 2021

Design is increasingly entering planning beyond the subfield of urban design. At a larger scale, designers are moving into the social sciences to apply design skills at intersections with the social sciences. This article offers an overview of research and practice at the forefront of both interpreting design fields and understanding their growing importance within planning. This transcends examinations of urban design to incorporate the potential of design more broadly in planning, with particular emphasis on community development and engagement. The article does this through a case study of an existing design-based nonprofit (bcWORKSHOP) which leverages techniques across design and planning to generate new forms of community planning practice in the State of Texas. Ultimately, this case study begins to ask whether planning can fully address a number of issues (like social/racial justice and climate change) without understanding these issues from both design and planning perspectives simultaneously. It also emphasizes the importance of training planners to both envision and build alternate possible worlds, a skillset fundamental to design that could reshape planning education and practice.
Urban Planning Academics: Tweets and Citations
Authors: Sanchez Thomas W.
Published: February 2021

This article discusses the relationship between Twitter usage and scholarly citations by urban planning academics in the U.S. and Canada. Social media and academic publications may be considered separate activities by some, but over the past decade there has been a convergence of the two. Social media and scholarship can be complementary not only when social media is used to communicate about new publications, but also to gather research ideas and build research networks. The analysis presented here explores this relationship for urban planning faculty using data for faculty who had active Twitter accounts between March 2007 and April 2019. Measures of Twitter activity were combined with Google Scholar citation data for 322 faculty with Twitter accounts. As expected, the results highlight that there are different patterns of Twitter activity between junior faculty and senior faculty both in terms of proportions of each rank using Twitter as well as activity levels on the social media platform. The results also suggest that Twitter activity does not have a statistically significant relationship with overall scholarly productivity as measured by citation levels.

Innovations and Development in Urban Planning Scholarship and Research
Authors: Sanchez Thomas W.
Published: February 2021

Urban planning is characterized by involving a wide range of experts from a variety of fields. Therefore, planning research draws upon each of these fields in how it interprets an examines the natural and built environment as elements of human settlement activities. As a small professional and academic discipline incorporating aspects of design, policy, law, social sciences, and engineering, it is understandable that research outcomes are published in a broad range of academic outlets. It is useful for us to reflect on our research intentions, processes, and outcomes, which is also referred to as ‘research about research,’ with a focus on the scholarly products of urban planning academics. We can do this by examining our methodologies, subdomains, application of research to practice, research impact, and bibliometrics. The purpose of reflecting on our research helps us better understand research processes and the resulting body of urban planning research and scholarship as a whole.

Authors: Rosso Fernando Luis de , Huff Alexandre Ausani , Dal-Farra Rossano André , Bayer Arno
Published: February 2021

Background: The study of the history of mathematics teaching can be approached from different perspectives, defining contours from which the researcher performs the analysis focused on a process characterised by continuity, or by adopting periodisation. Objective: In this article, we seek to conduct a study based on the delimitation of periods, according to Le Goff’s (2014) argument, and in the light of the depth hermeneutics, based on Thompson (2011). Design: Given the premises above, we conducted a documentary analysis of two historical processes within the scope of mathematics teaching, one focusing on the municipal public schools of Canoas, and the other on a technical course in chemistry of a school in the city of Novo Hamburgo, both in the state of Rio Grande do Sul. Setting and participants: A timeline with conspicuous events used to periodicise both historical processes analysed by the authors. Data collection and analysis: Analysis of documents relevant to the history of the technical school investigated and education in the municipality of Canoas. Results:  In both cases, it was possible to characterise the historical processes in periods based on events and official documents that generate changes in mathematics teaching. Conclusions: The historical processes analysed are characterised by ruptures resulting from changes, especially in the legislation, both in the municipal public network and in the technical education institution researched, enabling the realisation of changes and the characterisation of distinct periods, with their nuances.

Published: February 2021

The article is devoted to the results of using system-defined geological modeling for forecasting gold deposits on the territory of the oldest gold mining region in the Republic of Kazakhstan – the West Kalba gold belt (East Kazakhstan). Research is aimed at developing forecast criteria and searches for new ore objects in favorable geological structures. The main attention of the conducted research was focused on a system-defined analysis of geological factors, the interaction of which provides a synergy effect and reveals the patterns of formation of gold ore objects. To solve this problem, the authors made a quantitative assessment of the development sustainability of the ore-generating elements of the system according to S.V. Vasiliev methodology.

A quantitative assessment of the stability of individual factors and their interaction made it possible to assess the qualitative state of individual sections and define the natural boundaries of the areas of the corresponding hierarchical level, promising for the search of certain mineral deposits.

The specific work was carried out to define the areas promising for the search of deposits based on a quantitative assessment of the individual factors stability. Using geological materials, results of geophysical work, space-geological data, the localization of promising areas within the West Kalba structural-formation zone and the Zhumba ore-magmatic system in East Kazakhstan was done.

Forecasting Induced Earthquake Hazard Using a Hydromechanical Earthquake Nucleation Model
Authors: Rubinstein Justin L. , Barbour Andrew J. , Norbeck Jack H.
Published: February 2021

In response to the dramatic increase in earthquake rates in the central United States, the U.S Geological Survey began releasing 1 yr earthquake hazard models for induced earthquakes in 2016. Although these models have been shown to accurately forecast earthquake hazard, they rely purely on earthquake statistics because there was no precedent for forecasting induced earthquakes based upon wastewater injection data. Since the publication of these hazard models, multiple physics-based methods have been proposed to forecast earthquake rates using injection data. Here, we use one of these methods to generate earthquake hazard forecasts. Our earthquake hazard forecasts are more accurate than statistics-based hazard forecasts. These results imply that fluid injection data, where and when available, and the physical implications of fluid injection should be included in future induced earthquake hazard forecasts.
Tests of Remote Dynamic Aftershock Triggering by Small Mainshocks Using Taiwan’s Earthquake Catalog
Authors: Peng Wei , Toda Shinji
Published: February 2021

To understand earthquake interaction and forecast time-dependent seismic hazard, it is essential to determine which static or dynamic stress change due to a mainshock plays a major role in triggering its aftershocks and subsequent mainshocks. Using small mainshocks (2≤M<3) and their aftershocks, Felzer and Brodsky (2006) argued that mainshock induced dynamic stress change is responsible for earthquake triggering in a form of power-law decay within 50 km. Richards-Dinger et al. (2010), however, studied the foreshock decay and claimed that mainshock had no effect at distances outside its static stress triggering range, which required an alternative explanation. We tested these hypotheses using Taiwan’s earthquake catalog by taking advantage of its lack of large events and the absence of active volcano and associated significant seismic swarm. In examining earthquakes occurring in 1994–2010, following Felzer and Brodsky’s method, we found a linear aftershock density with a power-law decay of −1.12±0.38 that is very similar to the one seen in Felzer and Brodsky (2006). None of the mainshock–aftershock pairs were associated with an M 7 rupture event or M 6 event. We further demonstrated that the density decay in a short time period is more likely a randomized behavior than mainshock–aftershock triggering. These pairs were located mostly in high geothermal gradient areas, which are probably triggered by a small-scale aseismic process.

This research was developed in the frame of the VOLTO JÁ Project, which aims to implement a senior social exchange program in Portugal, among social economy organizations to promote tourism experiences for the elderly. The main goal of the research is to present a three-stage model of designing and evaluating tourism experiences in senior mobility, named as the OEC Model. This model was established based on a set of data collection instruments, which were chosen according to the goals of each stage of the process, in the context of the VOLTO JÁ Project. The results of stage one and three of the model considered as a more integrated approach on designing and evaluating senior tourism experiences are presented. The findings highlight the importance of a pre-stage in what concerns organizing the tourism experience (supply perspective); and a post-stage assessing senior´s perceptions after the experience (demand perspective).

Nowadays, the Internet of Things is used to transfer information from human to human and from human to machine. In this paper, we propose the use of IoT platforms to link those homes that are equipped with IoT capabilities, in order to increase security and prevent from a crime to a fire, and even monitor health status of a person. Using a microcontroller, it is possible to send information to a cloud server capable of sharing this information with other households connected to the platform, as well as allowing linking this data to one of the most used social networks in the world: Facebook. Linking smart homes with social network, allows to consult the status of sensors and IoT devices empowering citizen security against crime, violence and events that could put the integrity of people at risk both in their property and their health. The study is carried out for a particular region of Latin America, given its high rates of violence against citizens that have occurred in recent years.
