Authors: Demina I. F.
Published: December 2020

During the research, there were studied 186 varieties of spring soft wheat of different ecological and geographical origin to develop valuable initial material for new varieties in the conditions of Middle Volga. The studies were carried out in accordance with the methodic recommendations of VIR. According to the duration of the growing season, the samples were divided into three groups: early ripening – 29.4 %, mid-ripening – 45.0 % and mid-late-ripening – 25.6 %. The largest number of high-yielding varieties belongs to the mid-ripening group. Five groups are distinguished according to plant height: above 120 cm – tall, 120-105 cm – medium-grown, 104-85 cm – undersized, 84-60 cm – semi-dwarfs, less than 60 cm – dwarfs. A group of semi-dwarfs showed high resistance to lodging. The yield of productive genotypes in this group is 192-210 g/m2. The analysis of the elements of the yield structure showed the varieties that exceeded the standard in the number of grains in the ear (32.8 pcs.): Annet (38.2 pcs.), Baganskaya 95 (36.5 pcs.), Riks (37.7 pcs.), Lubninka (36.8 pcs.), (Russia, West Siberian Region), Biryusa (37.2 pcs.) (Russia, East Siberian Region), by grain weight per ear – Russian varieties from East Siberian, West Siberian and Lower Volga Regions (0.96-1.52 g), and varieties of foreign selection from North America (0.89-1.64 г). According to the yield the following varieties significantly exceeded the standard variety Kinelskaya Niva (310 g/m2) by 30-54 g/m2 (LSD05 = 22.5 g/m2): Russian varieties Annet, Baganskaya 95, Lavrusha, Tarskaya 10, Pamyati Maistrenko, Omskaya 39, Duet (West Siberian region), Voevoda (Lower Volga region) and Uyarochka (East Siberian region), foreign varieties Aktyube 10 (Kazakhstan) and Granit (Canada). The varieties with complex resistance to the main types of leaf diseases (leaf rust and powdery mildew) have been identified: Norwell, Granit, Dandy, CDC Merlin (Kanada), Lavrusha, Tarskaya 10 (West Siberian Region), Tybalt (Netherlands), Voevoda (Lower Volga Region), Etyud (Ukraine). The identified varieties were used as parental forms in crosses.

Authors: Traburova E. A. , Rozhmina T. A. , Andreeva I. A.
Published: December 2020

The research was carried out in 2017-2019 in the conditions of the Smolensk region on sod-podzolic medium loamy slightly acidic soil. The study included 25 varieties and lines of fiber flax of domestic and foreign selection. The mid-ripening variety Impuls (Russia) was used as a standard, whose yield, depending on the test year, was 1.07...1.29 t/ha. As shown by the calculations of the index of environmental conditions, the most favorable conditions for fiber flax developed in 2018 (Ij = +0.46), and stress conditions, caused by excessive moisture during the critical period of plant growth and development (GTC = 1.7), in 2017 (Ij = -0.55). On average, over the years of research, the yield of fiber, depending on the genotype, varied in the range of 1.00...1.97 t/ha. The highest yield on average for three years of testing (1.78...1.97 t/ha) and average yield in contrasting conditions were characteristic of the varieties Cesar, Sinel, Dobrinya (Russia), Marylin (Holland), Andrea, Altea (France). Under favorable weather conditions (2018), a high potential for the yield of flax fiber compared to the average value (121.5...133.3 %) was obtained in the varieties Cesar, Dobrinya, Sinel (Russia), Belita (Belarus), Andrea, Altea (France), Marylin (Holland). Under stressful conditions (2017), high adaptability was found in the samples of the Russian selection Cesar (173.4 %), Sinel (168.0 %), Dobrinya (151.1 %), Tost 3 (128.7 %), Alfa, Universal (127.7 %). The varieties Surskiy (bi = 2.2), Belita (Belarus), l. 323-02 (Russia), Marylin (Holland) − 1.7, Alexandrit (Russia), Andrea (France) – 1.5. Were characterized by high responsiveness to cultivation conditions (bi> 1). Russian varieties with a relatively stable yield: Cesar, Sinel – 0.7, Alpha – 0.6, Lider, Smolich, Tost 3, Universal – 0.5, Impuls – 0,2 did not show reaction to changes in growing conditions (bi <1). Thus, the domestic varieties Cesar, Dobrinya and Sinel have the highest yield of flax fiber and adaptability to the soil and climatic conditions of the Central Non–Black Earth Region. Expansion of fiber flax acreage under these varieties will provide strengthening of the domestic raw material base.

The studies were carried out in the southern part of the Rostov region in 2017-2019 on typical carbonate chernozem. Studied was the efficiency of periods of ammonium nitrate application (N30, N30+30) in autumn when the vegetation season is finished, in spring in the thawed soil, and during the tillering phaseon the yield and quality of winter wheat grain of Krasa Dona variety by different seed sowing rates (500, 600, 700 pcs/m2). Soft winter wheat variety Krasa Donacultivated after sunflower has shown a good reaction to double nitrogen top-dressing in autumn and in spring (N30 in autumn when the autumn growing season is finished + N30in spring on thawed soil). In this variant there has been formed the largest yield of 6.09-6.18 t/ha. The productivity excess over the control variant (without nitrogen top-dressings) was 2.38-2.63 t/ha, depending on the seeding rate, which significantly exceeded the level of LSD05in the experiment (LSD05= 0.24 t/ha). In addition, in this variant with the seeding rate of 500 pcs/m2the maximum economic efficiency was obtained. The profitability was 121.3 %, and the contingent net income was 34,268 rub/ha. The application of nitrogen fertilizing provided an increase in the mass of 1000 grains to 42.6-43.0 g (39.8-40.2 g in the control) and increased the gluten content in the grain to 20.5-21.8 % (18.6-18.8 % in the control).

Para las mujeres actualmente nacidas y residentes en los países democráticos, acudir a las urnas se ha convertido en un evento relativamente común, casi lógico, al igual que la posibilidad de acceder a cualquier profesión y carrera formativa o poseer propiedades en exclusiva, sin que estas formen parte automáticamente del patrimonio de su esposo tras el matrimonio. Pero para obtener estos derechos civiles que hoy se consideran básicos, fue necesario un siglo de lucha constante por el reconocimiento de la ciudadanía plena. En su época, las luchadoras y luchadores que batallaron durante años para vencer los prejuicios, enraizados en la sociedad y alimentados durante siglos, con sus acciones colectivas, sus reivindicaciones y sus textos, lo llamaron “La Causa”. Con C mayúscula, porque lo consideraban el primer gran paso que necesitaban dar para llegar a alcanzar, un día, la verdadera igualdad plena, tanto ante la ley como en las costumbres…
El I Congreso Internacional de la Mujer (1970). La Sección Femenina de Falange se reinventa
Authors: Camino Rodríguez Alejandro
Published: December 2020

El Congreso Internacional de la Mujer es un marco privilegiado para analizar las tensiones que vivió la Sección Femenina de Falange durante el tardofranquismo. También ofrece un contexto ideal para estudiar en profundidad el discurso de género que sostuvo la Sección Femenina en este periodo, ya que los límites de su modelo de mujer socialmente aceptable fueron muy diferentes a los planteados en los años cuarenta y cincuenta. Aparte de los cambios producidos en el propio pensamiento de la organización, las falangistas sintieron la necesidad de adaptar este modelo a las nuevas vivencias de las españolas, que se habían visto modificadas por las transformaciones socioculturales y económicas que estaba experimentando el país. Además, la investigación del congreso permite estudiar las estrategias que desarrollaron contra el mismo las organizaciones de mujeres democráticas y de izquierdas, así como los beneficios e inconvenientes que estas actuaciones les desencadenaron.
Comunistas y católicas en Cuadernos para el Diálogo. La contribución de la revista al debate sobre la situación de la mujer en el mesofranquismo
Authors: Pando Ballesteros María de la Paz
Published: December 2020

En 1965 la revista Cuadernos para el Diálogo publicaba un número monográfico titulado “La mujer” en el que colaboraba un nutrido número de mujeres y hombres de diferente orientación, que dejaron constancia de su percepción y de la de los distintos grupos ideológicos a los que pertenecían, acerca de la situación de las mujeres en la España del momento. El análisis de este interesante número, muchas veces citado aunque nunca objeto de un análisis específico, nos permite valorar la contribución de la revista, entonces de orientación democristiana, al debate teórico, a la construcción de un nuevo pensamiento sobre la mujer y a la renovación del modelo femenino de la dictadura, que despegaba en España en las fechas señaladas. Por otro lado, su análisis nos permitirá apreciar la entidad de la movilización de las españolas y su capacidad de acción, a través de los incipientes grupos organizados, en un momento en el que la dictadura iniciaba su recta final.
Del Génesis a Christian Dior. Tensiones y cambios en el matrimonio franquista a través del cine (1958-1963)
Authors: Rincón Aintzane
Published: December 2020

En el tránsito de los años cincuenta a los sesenta, y dentro del cambiante contexto del régimen franquista de la autarquía al consumo de masas, se dieron importantes transformaciones en el terreno de las relaciones de género que afectaron, también, a la institución matrimonial. El análisis de la película ‘Los derechos de la mujer’ (Sáenz de Heredia, 1963), centrada en las agitadas relaciones matrimoniales de María José y Juan, me servirá como eje argumental para el estudio de las tensiones y las resistencias que en aquellos años se produjeron en las formas de comprender la masculinidad y la feminidad y la relación conyugal entre ambas. Además, plantearé la posibilidad de que el relato de la ‘guerra de sexos’ pudo ser utilizado para responder a un estado de malestar incipiente al que más tarde se le daría un carácter colectivo y político en clave feminista.

Majority of UAE construction works were reported experiencing changes during execution process which exerts adverse effects to project success. Among the negative impacts is the failing in achieving satisfactory schedule performance. This poor schedule performance is also common issue faced by construction works globally. This paper addressed a study on various client related factors causing changes and parameters that affecting project schedule performance. The study was conducted through quantitative method. The data was gathered through questionnaire survey amongst the practitioners from contractor and consultant organization engaged in construction project of UAE and analysed statistically using significant index value. Results obtained in this study highlighted lack of coordination, replacement of key personnel by clients and inadequate understanding of clients need as three major issues related to client which are responsible for changes in construction works. While delay in completion schedule, slower project progress and dispute between owner & contractor are as major parameters affecting schedule performance. For correlation analysis, it was found that lack of coordination between the parties has significant correlation with delay in completion schedule, and dispute between owner & contractor. Also replacement of key personnel from client has significant correlation with schedule delay that are additional works and re-work/redesign. These finding will be helpful for practitioner in prioritizing the factors of change and schedule measuring parameters for improving schedule performance.

Authors: Plyakin Vladislav , Protasov Vladislav
Published: December 2020

The problem of formalizing and automating the process of recognizing human faces was touched upon at the earliest stages of the development of image recognition systems and remains relevant to this day. Moreover, over the past ten years, the number of scientific studies and publications on this topic has increased several times, which indicates an increase in the urgency of this problem. This can be explained by the fact that modern computing technology opens up new possibilities for its application in various fields, and, accordingly, a lot of applied problems have appeared that require their speedy resolution. One of the practical applications of the pattern recognition theory is face recognition, the task of which is to automatically localize a face in an image and identify a person by face. The interest in the procedures underlying the process of localization and face recognition is quite significant due to the variety of their practical applications in areas such as security systems, verification, forensic examination, teleconferences, computer games, etc. For example, the face recognition system developed at Beijing Tsinghua University has been certified by the Chinese Ministry of Public Security for use in public places. Omron Japan, which specializes in recognition, automation and control technologies, has developed a human face recognition system for mobile phones. Riya, founded by a group of specialists in facial recognition algorithms from Stanford University, has begun open testing of a Web service for contextual search of facial images in digital photo albums. The abundance of such examples indicates the practical importance and relevance of face recognition methods.

Authors: Kurilov A.
Published: December 2020

Analysis and interpretation of multidimensional data is a very important problem in many spheres of human life, such as production of products, diagnosis of diseases, marketing, information security, etc. However, sometimes the analysis of multidimensional data using traditional approaches is difficult. Since a person perceives visual information better and faster, visualization is used to analyze the data and identify patterns in the data. There are many ways to visualize multidimensional data. However, visual models built in these ways show different degrees of effectiveness for different tasks. Therefore, it is necessary to identify criteria by which to evaluate the effectiveness of the resulting visual model. This article describes the process of obtaining comparison criteria for visualization metaphors by examining visual models of multidimensional data and their visualization metaphors.

On conditional "safety grades" of power units of NPPs of the Russian Federation
Authors: Arzhaev Alexey
Published: December 2020

The energy obtained at nuclear power plants is considered environmentally friendly, so an increase in the number of nuclear power plants is inevitable both in Russia and abroad. But the memory of accidents and incidents at nuclear power plants, their causes and destructive consequences should force all responsible participants in the process to follow the basic principles of defense in depth and safety culture. Analysis of the factors considered in the article indicates that the approach to the implementation of the principle of safety culture on the part of officials of the State Atomic Energy Corporation Rosatom and the world's second operating organization, Rosenergoatom Concern JSC, is subject to emasculation to the greatest extent. This indicates that the lessons of past accidents at nuclear power plants are not fully absorbed in the nuclear industry of the Russian Federation and the existing bureaucratic nihilism in relation to the fulfillment of the requirements of federal norms and rules requires urgent overcoming.

Development of the scoring model for assessing the probability of expulsion of university students
Authors: Slavyanova Yana , Lagerev Dmitriy
Published: December 2020

The work of most information systems involves the processing of data, its accumulation during operation and subsequent analysis. However, the analysis of such a large amount of information by a person is impossible without its preliminary automatic processing. For this purpose, Data Mining is used, which includes descriptive and predictive modeling. The statistical classification is one of the most understandable data analysis technologies for humans and relates to predictive modeling. This task consists in dividing the set of observations into classes based on their formal description. One of the methods for solving the classification problem is logistic regression, while scoring is a common area of application. This article discusses the application of scoring to the problem of assessing the probability of students' expulsion from the University based on data on their attendance and academic performance. The solution of this problem will allow curators of groups, directions and other interested parties to identify the tendency to expulsion in time, identify a risk group among students and take early measures to prevent the event predicted by the built model from becoming a fact. The built scoring model is subject to publication as a web service for further use in the software package for supporting the work of a University teacher. In this case, the model input receives aggregated characteristics obtained from accumulated data on student performance and attendance by the software package, which results in an integrated indicator of the probability of an event, namely, deductions. As a result of building a scoring model, a subsequent assessment of its quality is performed.
Study of the residual uncertainty of messages circulating in hierarchical systems
Authors: Baskakov A. , Klimenko Igor
Published: December 2020

It is shown that when performing operational control procedures that ensure the routine operation of hierarchical systems, the task of maintaining controllability is reduced to fulfilling the conditions for isomorphism of the set of its states and the set of control actions. With the implementation of hierarchical management at the tactical and strategic levels, proceeding under conditions of in-complete certainty, the probability of a positive feedback objectively increases, which can lead to a further increase in uncertain-ty and, ultimately, to a loss of control.

Authors: Viunova A. , Zolotarev Oleg
Published: December 2020

Currently, the problem of improving satellite navigation systems has gained sufficient popularity. This is due to the fact that a lot of both civilian and military objects are somehow connected with satellites (navigators for civilians, tracking systems in the military sphere, etc.). Unfortunately, when implementing satellite navigation systems in various industries, one has to face a number of problems. Namely, with very low positioning accuracy of the required objects. This is due to the dynamism and mobility of satellites relative to the Earth. That is why stationary ground objects are introduced to improve positioning accuracy. In connection with the above problems, the topic of the work is quite relevant today.

This project is aimed at developing models, algorithms and a software package for measures to improve safety and reduce risk in the design of new and operation of existing nuclear power plants. The principal novelty of the project is the development of a methodological apparatus for assessing radiation risk at nuclear power plants during the most dangerous (beyond design basis) accidents involving the emission of thermal neutron sources with a low flux density. Nuclear reactors based on the use of fission energy of heavy nuclei are powerful sources of gamma radiation and neutrons. The project is aimed at computer modeling and the development of new methods, algorithms and a software package for solving the problems of assessing safety and risk at nuclear power plants in the most dangerous (beyond design basis) accidents with the emission of thermal neutron sources with a low flux density. To implement the project, it is necessary to develop a methodological approach to solving the problems of assessing the doses of external and internal radiation and assessing the damage to the population living around nuclear power plants during the most dangerous (beyond design basis) accidents with the emission of thermal neutron sources with a low flux density; make cal-culations for the population, given its age composition. Based on these decisions, measures will be proposed to reduce the risk and improve the safety of nuclear power plants.

Teachers consistently identify working with “diverse learners” as challenging. This raises questions about how teacher educators conceptualize and enact preparation of teachers for heterogeneous populations. This article provides a systematic review of literature relating to both “teacher education” and “diverse learners,” to identify knowledge claims regarding the way this “problem” and possible “solutions” should be framed. Analyzing 209 peer-reviewed journal articles (2009–2019), the article identifies groups most frequently described as diverse, three qualitatively different clusters of claims regarding how teachers can be prepared for diversity, and factors identified as constraining preparation. Analysis reveals a literature broad in focus—referencing many groups—but shallow in depth. The majority describe strategies for teaching about or catering to diversity with only few considering teaching for diversity. There is also limited engagement with specialist literature relating to concepts such as gender or race and little attention to teacher educators’ own knowledge. The article concludes with implications for teacher educators, arguing for enhanced critical epistemic reflexivity.

Published: December 2020

Contingency Theory merupakan teori yang mengadopsi pendekatan kontingensi untuk memahami dampak Strategic Orientation (SO) terhadap performa perusahaan dalam konteks Turbulensi Teknologi (TT) yang dinamis. Mendefiniskan Teknologi sebagai Variabel Moderasi menawarkan konsep teknologi yang holistik bagi nilai bisnis. Kemampuan teknologi meningkatkan harapan perusahaan untuk mencapai kinerja yang lebih baik. Turbulensi Teknologi (TT) berfungsi sebagai faktor kontingensi primer atau Independen yang difokuskan pada SO sebagai determinan utama FP.Pandangan tradisional menunjukkan bahwa resiko tinggi berpotensi menawarkan hasil yang tinggi dengan memperkenalkan Turbulensi teknologi informasi sebagai variable moderasi dan juga Risk Taking Behavior sebagai variable Independent. Mediating effect disini diartikan sebagai efek yang dihasilkan dari adanya Variabel mediator yang saling menghubungkan Independent variable dan Dependent Variabel. Tujuan Variabel mediator adalah menjelaskan hubungan antara IV dan DV. Variabel Mediator merupakan variable perantara atau penengah antara Independent variable (IV) dengan Dependent variable (DV) hal ini diperlukan sehingga antar variable bisa bekerja secara baik atau mediating effect dikatakan sukses

The Brokerage Roles of City-Regions in Global Corporate Networks

Published: December 2020

City-regions are conferred economic advantage through their brokerage roles, which close structural holes between other city-regions that would otherwise not be connected within firm networks. Here, we identify city-regions whose brokerage roles are defined by their network positionality as intermediaries using flows based on ownership relations between headquarters and subsidiary locations. Applying Gould and Fernandez’s framework of five potential brokerage types, we find city-regions play one or more brokerage roles characterised by both global and domestic flows. Moving beyond understandings of brokerage as a position, we explain diversity in brokerage as defined by economic processes underlying urban networks.
Does spacetime inherently has von Neumann entropy?
Authors: Icefield William
Published: December 2020

There has been considerable difficulty in equating thermodynamic entropy, suggested in classical and black hole thermodynamics, with von Neumann entropy. Successful derivations of black hole entropy from purely classical origins and recent doubts as to whether we can really equate von Neumann entropy with thermodynamic entropy open up the possibility that spacetime inherently encodes entropy. In this understanding, any quantum theory defined on some spacetime or worldsheet inherently calls for another quantum theory that explains entropy encoded by spacetime.

Identifying and Measuring Conditional Policy Preferences: The Case of Opening Schools During a Pandemic

Published: December 2020

An individual’s issue preferences are non-separable when they depend on other issue outcomes (Lacy 2001a), presenting measurement challenges for traditional survey research. We extend this logic to the broader case of conditional preferences, in which policy preferences depend on the status of conditions with inherent levels of uncertainty -- and are not necessarily policies themselves. We demonstrate new approaches for measuring conditional preferences in two large-scale survey experiments regarding the conditions under which citizens would support reopening schools in their communities during the COVID-19 pandemic. By drawing on recently-developed methods at the intersection of machine learning and causal inference, we identify which citizens are most likely to have school reopening preferences that depend on additional considerations. The results highlight the advantages of using such approaches to measure conditional preferences, which represent an underappreciated and general phenomenon in public opinion.
EFEK MEDIASI TERHADAP KEPUASAN KINERJA KARYAWAN DENGAN HUBUNGAN KEPEMIMPINAN YANG EFEKTIF DALAM SITUASI TERTENTU

Sistem pengawasan manajemen yang baik, dapat mengindikasikan wujudnya satu sistem pengawasan yang dapat memaksimalkan pengaruh manajemen (Lowe, 1971). Selaras dengan pandangan tersebut, (Fisher, 1995) menjelaskan pengawasan merupakan suatu aktivitas dalam keadaan tertentu dapat mendorong organisasi untuk mencapai apa yang dicita-citakan atau diharapkan pada waktu tertentu dimasa depan. Seterusnya, menurut (Hambrick, 1985) terdapat tiga asas pendekatan di dalam mengkaji pengaruh sistem pengawasan manajemen ke atas kinerja yaitu pendekatan kontingensi, pendekatan keadaan umum dan perdekatan keadaan khusus.
Analytical relationships for re-entrant honeycombs
Authors: Hedayati Reza , Ghavidelnia Naeim
Published: December 2020

Mechanical metamaterials have emerged in the last few years as a new type of artificial material which show properties not usually found in nature. Such unprecedented properties include negative stiffness, negative Poisson’s ratio, negative compressibility and fluid-like behaviors. Unlike normal materials, materials with negative Poisson’s ratio (NPR), also known as auxetics, shrink laterally when a compressive load is applied to them. The 2D re-entrant honeycombs are the most prevalent auxetic structures and many studies have been dedicated to study their stiffness, large deformation behavior, and shear properties. Analytical solutions provide inexpensive and quick means to predict the behavior of 2D re-entrant structures. There have been several studies in the literature dedicated to deriving analytical relationships for hexagonal honeycomb structures where the internal angle θ is positive (i.e. when the structure has positive Poisson’s ratio). It is usually assumed that such solutions also work for corresponding re-entrant unit cells. The goal of this study was to find out whether or not the analytical relationships obtained in the literature for θ>0 are also applicable to 2D-reentrant structures (i.e. when θ<0). Therefore, this study focused on unit cells with a wide range of internal angles from very negative to very positive values. For this aim, new analytical relationships were obtained for hexagonal honeycombs with possible negativity in the internal angle θ in mind. Numerical analyses based on finite element (FE) method were also implemented to validate and evaluate the analytical solutions. The results showed that, as compared to analytical formulas presented in the literature, the analytical solutions derived in this work give the most accurate results for elastic modulus, Poisson’s ratio, and yield stress. Moreover, some of the formulas for yield stress available in the literature fail to be valid for negative ranges of internal angle (i.e. for auxetics). However, the yield stress results of the current study demonstrated good overlapping with numerical results in both the negative and positive domains of θ.

Due to the change from mass production to mass personalized production and the resulting intrinsic product flexibility, the automotive industry, among others, is looking for cost-efficient and resource-saving production methods to combining global just-in-time production. In addition to geometric manufacturing flexibility, additive manufacturing offers a resource-saving application for rapid prototyping and small series in pre-development. In this study, the FDM process was utilized to manufacture the tooling to draw a small series of sheet metal parts in combination with the rubber pad forming process. Therefore, a variety of common AM polymer materials (PETG, PLA and ABS) is compared in compression tests, from which PLA is selected to be applied as sheet metal forming die. For the rubber pad forming process, relevant processing parameters, i.e. press force and rubber cushion hardness, are studied with respect to forming depth. The product batch was examined by an optical evaluation using a metrological system. The scans of the tool and sheet metal parts confirm the mechanical integrity of the additively manufactured die from polymer and thus the suitability of this approach for small series in sheet metal drawing processes, e.g. for automotive applications.
