Un proyecto latinoamericano, una propuesta nacional
Authors: Lus Bietti Gonzalo Ezequiel
Published: December 2020

El objetivo del siguiente trabajo es indagar una propuesta disciplinar de Geografía que tuvo lugar bajo la rebautizada Universidad Nacional y Popular de Buenos Aires (UNPBA). Sin embargo, aquí no sólo se pretende conocer el desarrollo de un nuevo plan de estudios de la carrera de Geografía en el año 1974 en el marco reforma universitaria peronista (Ley Taiana), sino que también la intención es analizar dicho plan en diálogo con el proyecto latinoamericano de una Nueva Geografía. Teniendo en cuenta la crítica al nacionalismo metodológico, este trabajo apunta a comprender que la propuesta de Geografía de la UNPBA se fue forjando en un contexto reformista nacional a partir de vínculos y encuentros latinoamericanos que transgredían las fronteras del Estado-Nación.
Movimientos sociales e institucionalización: la especificidad de los movimientos socioterritoriales
Authors: Torres Fernanda
Published: December 2020

El presente trabajo se propone analizar los procesos de institucionalización que llevan adelante ciertos movimientos sociales específicos: los movimientos sociales que se apropian de un espacio para el desarrollo de sus proyectos políticos, definidos como movimientos socioterritoriales. Revisar el debate en relación con los riesgos y posibilidades que la institucionalización ofrece a los procesos de movilización, politización y transformación social que protagonizan los movimientos sociales supone, en el caso de los movimientos socioterritoriales, el análisis de sus territorios. Porque es a partir de ellos que desarrollan su estrategia, constituyen su identidad y sociabilidad política y, también, sus instituciones. De allí que proponemos un acercamiento espacial, bajo una estrategia cualitativa, para repensar la idea de instituciones y de ciudadanía a partir del análisis de las instituciones territorializadas de un caso de movimiento socioterritorial urbano, la Organización Barrial Tupac Amaru en Jujuy, Argentina.
Reverse Bloom
Authors: Shelley Arthur
Published: December 2020

Bloom’s Hierarchy of learning has been the foundation of formal teaching and assessment practice since the mid 1950’s. This has resulted in higher-quality education outcomes, more consistency in delivery, and better teaching practices. However, mainstream teaching practices and teacher training have focused on the Cognitive domain, with less focus on social development (except for some societies and non-mainstream institutions). There has been little emphasis on the two other domains for comprehensive learning, which Bloom’s colleagues identified as the Psychomotor and Affective domains. These two less used domains highlight the skills and social aspects of being able to influence others and apply the learning in practice to generate value. The imbalance between the three is critical because all three domains play a role in being a competent professional and a contributing member of society, based on the capabilities built in their learning experiences. 
This paper shares three key new contributions to the learning literature that help address this imbalance: The “Reverse Bloom Learning Framework” (RBLF), a set of principles to guide learning facilitation through the RBLF, and some insights on design of inclusive learning activities (including provision of deeper feedback for better reflection and higher quality learning outcomes). Together these three elements of progressive learning can enable a more balanced approach to learning at all levels. The RBLF includes all three of Bloom’s domains in iterative social learning experiences and reverses the traditional order of Bloom’s learning elements. The author suggests this more inclusive and comprehensive approach enables facilitation of more collaborative learning and that this will generate more competent, confident and capable graduates, who are better equipped to interact in our modern challenging workplaces and our wider world.
Equipping Parents for Effective HOME Schooling
Authors: Kinzer John , Herbst Nathaniel , Pohlman Philip , Herbst Erin
Published: December 2020

The COVID-19 crisis has shuttered schools across the globe and left millions of schoolchildren quarantined. This pandemic has highlighted the importance of adequately educating homebound children. Although homeschooling has been growing in popularity in some areas of the world, particularly in the United States, it has not constituted a large percentage of the educational establishment in any part of the world. There has been debate about homeschooling for decades. This paper aims to show that success with homeschooling is possible and it will provide suggestions for empowering families to achieve that. 
Four ways to empower home educators have been summarized into the HOME acronym. This acronym stands for (H) helping families find their fit, (O) offering a diversity of teaching resources, (M) making homeschooling socially acceptable, and (E) empowering homeschool partnerships. These practices can serve as a template for organizations that wish to support families who choose to homeschool their children or who are forced to by global constraints. 
The recent crisis has provided an opportunity for nations, organizations, families, and students to share the leadership of their educational resources and practices. Collaboration and cooperation can help ensure homebound children receive the education they need. This type of collaboration will help prepare the world for the educational challenges the future might bring.
Evaluating Mandarin Language Students’ Online Experience During Covid-19
Authors: Qing Li , Diamantidaki Fotini
Published: December 2020

Given the impact of coronavirus, all schools across all sectors public and private, in the United Kingdom closed at the end of March 2020. Closures affected every type of establishment across the UK as well as private language schools. Our case study takes place in London and looks into the student experience in a language Mandarin Chinese school. These language students, as very many across the globe, who attended face-to-face sessions up until that point, have since been studying remotely and joining virtual classrooms via Zoom, one of the multiple video conferencing platforms available. To better evaluate students’ online learning experience of remote learning, this study examines the teacher-student interactions that take place via online means and the students’ sense of ‘presence’ (i.e., cognitive, social, and teaching presence) in order to evaluate the lessons we can learn from the online learning experience, going forward in terms of teaching and learning. This study also presents how meaningful and worthwhile the experience has been and how the sense of ‘presence’ plays a significant role in the process of online teaching and learning.

İç kontrol sistemi; bir kurumda yönetim tarafından tasarlanan, varlıkların ve kaynakların korunması, faaliyetlerin etkili, verimli ve ekonomik yürütülmesi, kurum çalışanlarının yönetim politikalarına uyumlu hale getirilmesi, muhasebe kayıtlarının gerçeğe uygun tutulması, yönetime yeterli güvencenin sağlanma amacıyla oluşturulan bir sistemdir. Türkiye’de 2000’li yılların başından itibaren, AB (Avrupa Birliği) ile yapılan katılım müzakereleri sonucunda kamu alanında yapılan yasal düzenlemeler, iç kontrolün kamu idarelerinde önemini artırmıştır. Bununla beraber son yıllarda her alanda uygulama etkinliği genişleyen elektronikleşmenin iç kontrol faaliyetlerini de etkisi altına aldığı ve bu etkiyi giderek genişlettiği görülmüştür. Böylece; gelişmekte olan elektronikleşmeden etkilenen iç kontrol faaliyetlerinde kullanılmak üzere bazı yazılım firmalarınca ve kamu kurumlarınca geliştirilen e-iç kontrol yazılımları, sorumlu birimlerin kullanımına yönelik, özel sektördeki kuruluşları takiben kamu idarelerinde de yayılmaya başlamıştır. 2019 yılı sonu itibariyle dünyayı etkisine alan ve Dünya Sağlık Örgütü tarafındann pandemi olarak kabul edilen Covid-19 hastalığı, ülkemizi de etkilemiş bu süreç sonucunda kamu kurumlarında da esnek çalışma modeli kapsamında, elektronik ortamda uzaktan çalışmaya geçilmiştir. Bu süreç iç kontrol sistemini kurmakla yükümlü olan kamu idarelerinin E-İç kontrol sistemine geçmesini gerekli kılmaktadır. Literatüre yeni bir kavram olarak giren e-iç kontrolün kamu idareleri açısından kapsam ve uygulanabilirliğinin araştırılması, avantaj ve dezavantajlarının belirlenmesi, ayrıca pandemi sürecindeki öneminin tespit edilmesi bu çalışmanın temel amacını oluşturmaktadır. Çalışma kapsamında yapılan literatür çalışması ile iç kontrol sistemi kavramının kamu idareleri bazında yasal düzenlemelerdeki yeri ve önemi tespit edilmiş, yeni bir uygulama olan e-iç kontrol sisteminin özellikle pandemi döneminde kullanılabilirliği ile kullanılan yazılımların güçlü ve zayıf yönleri ve mevcutta uygulama etkinliği ortaya konulmuş ve gelecekte kullanımına yönelik öneriler geliştirilmiştir.

Authors:   D.A.  Shalikovskiy,  V.N.  Zaslonovskiy,  A.V.  Shalikovskiy
Published: December 2020

The article presents an approach to determining the flow rate of unexplored rivers depending on their order according to A. Scheidegger and the corresponding zoning. It is shown that the use of a single dependence of the flow rate on the river order gives significant errors for small streams. This is because of the fact that approximation function of the entire data file actually reflects regularities only for hydrological stations with great values of the runoff norm.For the territory of the Amur Basin within the Transbaikal cray, five regions have been identified, within which the dependences of the flow rate of small and medium rivers have values of the correlation coefficient from 0.95 to 0.97. An additional zoning scheme for the area under consideration has also been developed, which makes it possible to simplify the determination of the order of the river.The proposed scheme of flow rate determination includes the following operations: determination of the area according to the additional scheme – calculation of the river order – determination of the area according to the main scheme – calculation of the flow rate.

Authors:   A.A.  Tskhai,  V.Y.  Ageikov,  A.N.  Semchukov
Published: December 2020

The article presents a model description of spatially inhomogeneous features for the ecosystem of the Novosibirsk reservoir, the largest in Western Siberia, based on the reproduction of biogeochemical cycles of limiting elements. We have formulated the model tool set for studying quantitative and qualitative changes in the state variables of water bio/geo/cenosis. To obtain an adequate picture of environmental processes occurring in various parts of the reservoir modeling of the transformation features of nitrogen and phosphorus compounds in the waters of the Novosibirsk reservoir was performed in the box approximation. Phytoplankton biomass in a relatively shallow water area significantly exceeds concentrations in the deep-water and near-dam parts of the reservoir. A detailed dynamic picture of the variability of the content of pollutants, as well as oxygen, normalized by maximum permissible values, in the water areas of the reservoir is reproduced.The estimates obtained during the simulation generally correspond to the observed data. This study can serve as a basis for developing a model approach to monitoring and management of ecosystem processes in the Novosibirsk reservoir.

Authors:   I.I. Ivanenko, A.M. Novikova, E.Y. Lapatina
Published: December 2020

Increased hydrocarbon pollution of the natural environment and water bodies in recent decades has prompted the search for ways to reduce anthropogenic pollution. A number of modern environmental biotechnologies provide for the process of microbial introduction that is introduction of microorganisms with a useful function into the natural environment (soil and water bodies).The paper presents the results of laboratory studies on the rate of absorption of hydrocarbons by various microorganisms, the study of their hydrophilic/hydrophobic/adhesive properties, as well as the results of the search for a correlation between the degree of hydro/repellence of the cell surface and the rate of consumption of polluting hydrocarbon. Experiments on microbial separation of petroleum products from sand and Teflon surface made it possible to establish the possibility of this kind of destruction and determine the approximate treatment time depending on temperature. In terms of the degree of hydrophobicity, the bacteria strains involved in the decomposition process are placed in a series of activities that allows more successfully establishing the ratios of microorganisms-destructors in spatial communities for biological treatment of wastewater.

The paper presents the results of studies of the spectral properties of a photosensitizer based on indotricarbocyanine dye when accumulating in tissues of experimental animals. Using laser fluorescence spectroscopy, the in vivo and ex vivo fluorescence spectra of tissue-localized indotricarbocyanine dye were obtained for different time counts after intravenous administration. The profile of the pharmacokinetics of its accumulation and withdrawal was determined from the change in the intensity of fluorescence in the tumor and healthy muscle tissues of the photosensitizer. A monotonic deformation of its fluorescence spectrum was revealed in the tissues of tumor nodes and muscles of the thigh when registered through the skin over time after intravenous administration. The achievement of the maximum accumulation of the photosensitizer in the tumor correlates with the stabilization of the shape of its in vivo fluorescence spectrum. Thus, the maximum shift can be used as a diagnostic indicator of the maximum accumulation of indotricarbocyanine photosensitizer in the tumor tissues. The results were confirmed for two groups of animals: the first one – black mice of the C57Bl/6 line with an inoculated tumor of Clone M3 melanoma, the second – white mice of the ICR line with an inoculated tumor of Ehrlich ascites carcinoma. The analysis of the shape of the fluorescence spectrum of the photosensitizer during registration through the skin for animals with different colors has been carried out.

Musculoskeletal system disorders is one of the priority directions in dentistry. They can manifest as Kosten's syndrome, snapping jaw, painful dysfunction syndrome, increased tooth abrasion, splits, breaks, pain and spasms in muscles, etc. The study set the following objectives: to develop an algorithm for analyzing the movement pattern of the muscular-articular system by developing an algorithm for recording, analyzing, filtering and processing multichannel electromyograms of the maxillofacial muscles. Analysis of the proposed algorithm for processing multichannel electromyograms showed that 7.2 % of multichannel electromyograms could not be analyzed due to patients' violations of the movement algorithm; 8.7 % of electromyogram checkpoint values were corrected. The group without dysfunctions of the temporomandibular joint is characterized by the prevalence of the relaxation coefficient of the left temporal muscle over the coefficient of the right muscle. The dysfunctioned group has the opposite result. The value of the compression ratio of the temporal muscles exceeding 2.5 is typical for the group with dysfunctions of the temporomandibular joint. The studied groups differ as much as possible when analyzing the relaxation coefficients of the temporal muscles. When analyzing this coefficient, it was possible to truly determine the presence or absence of violations in 50 %, falsely – in 16 % of cases. The coefficient of relaxation of the masticatory muscles made it possible to obtain a true state of 24 %, a false one – in 8 %. We concluded that the compression ratio is less suitable for separating patients with and without dysfunction of the temporomandibular joint.

Published: December 2020

The study of the erosion activity of cavitation is of considerable interest for clarifying the mechanism of the effect of cavitation on biological tissues and cells. This paper proposes an improved technique for assessing the erosion activity of acoustic cavitation. The results of testing this technique in relation to the problem of studying the distribution of erosion activity in the cavitation region, generated by a radiator with a rod waveguide, are presented. The experiments were carried out using a submersible emitter with a resonant frequency of 32 kHz. It was found that erosion activity rapidly decreases with distance from the emitter and depends on the distance to the emitter L as 1/L3 when the diameter of the emitter is less than or of the order of the wavelength in the used liquid. It was shown that there is a correlation between the erosion activity of cavitation and the readings of the cavitometer with the output signal being the integral intensity of the highfrequency component of the cavitation noise in the frequency range up to 10 MHz. Piezoelectric sensors were used to register cavitation noise. In particular, in liquids characterized by a higher level of erosion activity, the output signal of the cavitometer is also higher. In this case, the readings of the cavitometer change depending on the distance to the radiator as 1/L. Based on the data obtained, a method is proposed for assessing the erosion activity of cavitation by the magnitude of the intensity of cavitation noise in a cube. It is shown that this parameter is linearly related to the results of measurements of the erosional activity of cavitation. The results obtained will be used in the development of a specialized cavitometer designed to assess the erosion activity of cavitation during in vitro studies of the effect of ultrasound on cells.

Wafers of Tb-doped GdAlO3/α-Al2O3 eutectic were fabricated by the micro-pulling-down method using an Ir crucible with a 25 × 25 mm2 die. A prototype X-ray phase imaging detector was developed using a CMOS sensor with a fiber optic plate and the eutectic wafer. X-ray spots with an 8.24 μm period were observed using the detector. X-ray phase imaging of a nylon ball with a diameter of 4 mm was also carried out. It was observed that a phase change of approximately 2 μm occurs at the air–nylon interface. This technique of X-ray phase imaging can be realized in the absence of an absorption grating.

Published: December 2020

Hyperfine interaction in a quantum dot produces a spin-coupled system between an injected electron and a few tens of thousands of nuclei in the electron wavefunction. We report here that the double bistable phenomenon of nuclear spin polarization (NSP) can be observed by sweeping three control parameters. All the observations indicate that the NSP has three stable branches under a longitudinal magnetic field, whereas the number of the stable branches of NSP has been believed to be two at most. The incorporation of the electron spin relaxation due to the nuclear spin fluctuation enables reproduction of the observed features of the NSP and the electron spin polarization.

In this research, we propose a method that can significantly improve the linearity of current–voltage characteristics (L–IV) of synapse devices. Considering that analog input data are dependent on the L–IV, synapse devices having non-linear current–voltage characteristics can result in drastic conductance variations during inference operations. It means that the L–IV is one of the key parameters in the synapse device. To improve the L–IV, a triode region of a metal oxide semiconductor field effect transistor (MOSFET) was utilized with a Li-ion-based memristor as a gate voltage divider, which results in gradual channel conductance changes (analog synaptic weights). The channel conductance of the MOSFET can be selectively controlled based on Li-ion intercalation and de-intercalation. A notably improved L–IV and analog synaptic weights were achieved, which enhanced the MNIST data set recognition accuracy from 35.8% to 92.03%.
High-efficiency scattering probe design for s-polarized near-field microscopy
Authors: Ren Richard , Chen Xinzhong , Liu Mengkun
Published: December 2020

In a conventional scattering-type scanning near-field optical microscopy setup, the atomic force microscope probe is unable to effectively couple with s-polarized light, resulting in low signal and limited in-plane sensitivity. This study aims to investigate a high-resolution probe with enhanced responsivity to both s- and p-polarized light. Full-wave electromagnetic method of moments simulations are utilized. Simulated near-field spectra on prototypical materials (SiO2, Si, SrTiO3), as well as simulated raster scans of a gap nanoantenna, indicate a two order of magnitude increase of the scattering signal for s-polarized incident and detection scheme compared to the conventional probe.

Authors: Alekhin M. Yu. , Titov A. V.
Published: December 2020

The presented study addresses the problems of managing the transformation of high-tech production systems (PS) to maintain the enterprise’s competitiveness in the long term.

Aim. The study identifies efficient approaches to forecasting the timeline, economic and social prospects of PS transformations.

Tasks. The authors assess the existing methodological framework for innovation management aimed at changing the scientific and technical potential of the PS and the government’s role in facilitating investment activity.

Methods. This study is based on the fundamental principles of systems theory and comprehensive consideration of the issues of managing changes in economic systems through analysis.

Results. The proposed assessments and comments can be taken into account when developing a methodology for forming an adequate management response to the predicted change in the external conditions of PS operation. The scientific and technical potential of high-tech enterprises is created, among other things, through long-term research, but the economic prospects of using research results are unpredictable. The experience of building the US national innovation system confirms the important role of the government in managing the commercialization of research results.

Conclusions. The development of the Russian economy depends on the timeliness and reasonable sufficiency of the formation of the scientific and technical potential of the PS. The formation of the Russian national innovation system is a prerequisite for creating a favorable institutional environment for innovation, and the authors believe that it will lay the groundwork for the reproduction of capital in real production and hedging of risks associated with these processes.
