For processing signals in the time area an efficient tool is the acousto-optic delay line (AODL). The smoothly controlled delay of signals in a broad time interval permits to build high-performance radiolocation simulators. In the work, the design of the AODL has been considered, and the parameters, determining the limit of using its potential have been noted. The features of photoelastic interaction in AODL have been considered for the case when the duration of the input pulse is shorter than the time of crossing the optical beam by an elastic wave packet. It has been found that under these conditions the duration of the output response is determined by the time of crossing the optical beam by an elastic wave packet and does not depend on the duration of the input action. It has been shown that the AODL response to the input action in the form of a rectangular pulse is determined as the sum of three terms. In this case, the process of the entry of the elastic wave packet into the optical beam determines the first term, the second one – by the process of propagation of the elastic wave packet in the optical beam aperture, and the third – by the process of the exit of the elastic wave packet from the optical beam aperture. The corresponding equations have been obtained for calculating the pulse parameters at the AODL output. It has been shown that for a sufficiently short input pulse duration, the output signal parameters contain the information on the energy-geometric characteristics of the laser radiation. The results of numerical simulation have been tested experimentally on AODL layout with the direct detection. A comparative analysis of the results of theoretical and experimental studies have unambiguously has confirmed that AODL can also be used at frequencies above the cutoff frequency, both in terms of its main functional purpose and for solving a number of other engineering problems.

While solving the tracking of objects for infrared range images the obtaining of the necessary volume relevant basis for neuron network training is problematic enough. The main obstacles are the absence of the far infrared range images base and the complexity of calibration of cameras of various manufacturers for composing the base. Due to these causes and the complexity of marking the borders of the given range objects using the neuron networks, at the moment, is not expedient. In the paper the principles of object tracking on the infrared range images, based on obtaining the key points using the SIFT, SURF, ORB algorithms, have been considered. The specific features of the given methods have been distinguished, and also, the specifics of far infrared range images and of the objects observed on it, has been emphasized. The analysis of the approaches to preserve the features of tracking an object in transition to a new frame of a video image has been performed, their main advantages and disadvantages have been revealed. Based on the obtained results the modernization of the tracking algorithm using the Jarvis algorithm modification has been proposed. The estimation of the influence on speed of additional processing in the tracking algorithm has been experimentally performed. The proposed approach to tracking an object on the infrared image, composed on the ORB algorithm key points and the application of the modified Jervis algorithm, is invariant to turns and scaling of the sought for object and allows to watch it in conditions of high nonhomogeneity of the background and presence of similar objects. The application of the developed algorithm permits to avoid a considerable loss of speed with a significant increase of the object tracking efficiency.

Researching of the main migration trends, their factors and management tools are relevant. The aim of the study is to develop a model of management of international migration flows in the modern conditions. Scientific and practical significance of work is in introducing the term of “world-migration” on the basis of the migration concept clarification. New trends in international migration have been identified and factors have been highlighted. The state management model of international migration has been developed, and indicators of its efficiency have been proposed. The results of this study is identification of sedentary lifestyle besides the traditional determinants of migration processes and the lack of breakthrough technologies for displacement. The role of the State had been transformed. Key role is ensuring migration security. The basis for an effective model of international migration public management is the search for a balance between openness and exclusion in a world of migration. The range of borders of the migration security indicator is defined. It ranges from the migration capacity of the labour market, which prevents the decline of the gross domestic product to the migration capacity of the labour market, which increases gross domestic product.

Published: March 2021

The analysis of the linguistic situation in the self-consciousness of the population with bi-ethnic Russian-Ukrainian identity in the south of Western Siberia is presented. The mixed Russian-Ukrainian language (“khokhlyatskiy” or surzhik), formed in places of concentration of the Ukrainian population, and the peculiarities of its existence are analyzed. Based on the data obtained during in-depth interviews in the summer of 2020, sociolinguistic factors affecting the linguistic situation in the region are described: the size of the ethnic group, the age of native speakers, the ethnic nature of marriages and the type of family education, language teaching at school. The level of proficiency in the Ukrainian language and surzhik depends on the period of resettlement, place of residence and age of the respondents. The author comes to the conclusion that the Ukrainian or “Khokhlyatskiy” language in the south of Western Siberia is assigned a more symbolic role in defining ethnic identity.

Identity and Concepts of History of the Bietnic Russian-Ukrainian Population of Russia
Authors:   Belgorod State University, Bublikov Vasily Valeryevich
Published: March 2021

Based on the data of a sociological survey carried out in 2020, the paper analyzes the ideas of the inhabitants of Russia with a double Russian-Ukrainian ethno-identity about the history of both (“mother” for this ethno-community) countries, as well as the connection of these ideas with identity. It was revealed that people with biethnical Russian-Ukrainian identity are much better aware of historical figures from the history of Russia than Ukraine. The history of Russia is personified primarily by military and political figures, while representatives of the cultural elite occupy a peripheral place. On the contrary, the history of Ukraine is equally associated with both politicians and military leaders, as well as with cultural figures. This perception of the history of the two countries is reflected in the identity of biethnic people. The Russian part of ethnicity is linked by them primarily with the state and those emotions that the state personifies (pride in the country, patriotism, etc.). On the other hand, the Ukrainian part is more often described by more intimate (family, private) emotions, i.e. those emotions that the cultural elite displays.

Published: March 2021

During the era of polarization in America, discussions about the role of the media in society, the objectivity, the freedom and the limitations of journalistic activity are intensifying. The position of the US journalistic community on these issues is reflected in codes of journalistic ethics. These documents point to the main priorities and values developed by journalistic collectives and organizations. The study shows the analysis of the categories of “freedom” and “restrictions” which presented in the codes of journalistic ethics of the United States. The analysis shows how often the terms associated with a particular category are found in documents. An important result of the research is an indicator of appeals to restrictions in the work of journalists. Many restrictions in journalistic activities are linked to the need to be accountable to the audience.
La dimensión material como propuesta analítica
Authors: Blanco Esmoris Maria Florencia , Ohanian María Jazmín
Published: March 2021

En este artículo proponemos la dimensión material como un clivaje significativo a analizar al momento de comprender las prácticas de diversos grupos socioculturales. Para esto, tomamos dos tramas conceptuales: la “biografía cultural de las cosas” y la noción de “situación social” y, ejemplificamos modos en que tales contribuciones permiten elaborar lecturas más densas sobre variados fenómenos como, por ejemplo: las protestas sociales. Partimos de la base que un diálogo entre el enfoque comunicativo y la mirada antropológica permite crear un fértil campo de posibilidades para entender la multiplicidad de procesos contemporáneos.
Comunicación y sentido común en sociedades latinoamericanas
Authors: Villalba Pérez Gabriel Alejandro
Published: March 2021

Las nociones sobre Sentido Común y Sociedades Democráticas se abordan desde elementos comunicacionales que permiten interpretar la realidad social multidimensionada, deconstruirla, proponer su reconfiguración y articular la Comunicación como fuente de transformaciones sociales. Se desarrolla una diferenciación de matrices, abordajes y enfoques comunicacionales que permiten entender cada elemento comunicacional en función a metas y objetivos concretos de orden cuantitativo y cualitativo. Se proponen estrategias de gestión comunicacional inherentes a las diversas formas de organización popular que permiten perfeccionar la participación democrática a través de elementos comunicacionales, entendiendo que el Sentido Común de las sociedades se encuentra en permanente disputa, construcción y reconfiguración en torno al sentido de época y los momentos históricos particulares. Se brindan nociones de interpretación de la realidad social latinoamericana a partir de la Comunicación, pero también propuestas de transformación entendiendo que las sociedades latinoamericanas son heterogéneas muy diferentes a las sociedades europeo continentales y a las anglosajonas. La Comunicación es enfocada a través de sus estrategias comunicacionales como primaria para la interpretación y transformación social, no así accesoria como se teoriza desde el Pensamiento Crítico. A la vez, todo el trabajo devela que no son únicamente los medios hegemónicos de comunicación ni exclusivamente los políticos los únicos actores constructores de Sentido Común en las sociedades.
EL margen, la violencia y sus fronteras
Authors: Mastronardi Bárbara
Published: March 2021

En este artículo analizo crónicas y fotografías publicadas en los diarios Clarín y La Nación que representan a la figura del joven, varón y pobre y a los territorios que habitan en relación a la violencia durante el período  2004 – 2014. Para ello, parto de una perspectiva metodológica que realiza un cruce analítico entre antropología, semiótica y análisis cultural. Entre los resultados de esta investigación se encuentran la deconstrucción del lugar de enunciación desde donde se muestran a estos sujetos y territorios, la identificación de metáforas que funcionan como organizadoras en la delimitación y marcación de fronteras y la descripción de los elementos – signos que convierten a estos sujetos y territorios en objeto de representación. La conclusión es que estas  operaciones y mecanismos discursivos colaboran en la co-producción de una imagen estigmatizada  y criminalizante que reproduce los mecanismos de legitimación de la desigualdad social.
Discurso de derecha y resistencia frente al cambio constitucional
Authors: Alarcón Silva Mauricio Esteban , Godoy Berthet Carolina Andrea
Published: March 2021

En medio del estallido social, Chile logra un acuerdo político que determina una consulta ciudadana para decidir sobre el cambio de constitución vigente desde la dictadura militar. La consulta, fijada inicialmente para el 26 de abril de 2020, encuentra al país en una polarización ideológica sustentada en la posible afectación a los pilares del modelo neoliberal, su constitución.

El presente trabajo aborda el discurso de derecha a partir de un caso de propaganda electoral a favor de la opción Rechazo el cambio. Analiza el discurso en su dimensión ideológica, también aborda recursos multimodales que son analizados mediante semiótica visual y metáfora multimodal.

Se evidencia la construcción de un nosotros (Rechazo) que valora el orden y la capacidad de elegir y soñar un país, que se distancia de un otros que engaña sobre una posible mayoría que se manifiesta en las calles. A través de elementos metafóricos apela a la amenaza de un enemigo con intenciones ocultas, representando a los políticos que usufructúan sin mayor esfuerzo de la democracia, en definitiva, tras el llamado a votar rechazo, un discurso coherente con las descripciones teóricas, que junto con restar valor a la participación, construye ideológicamente un enemigo al que se debe temer.

Las empresas periodísticas han comenzado a desarrollar nuevos modelos de negocio con el propósito de continuar haciendo del periodismo una industria rentable. Una de estas medidas, con un largo recorrido ya en el periodismo anglosajón, es el muro de pago o límite de visitas gratuitas en las ediciones digitales. El objetivo de esta investigación consiste en explorar, a través de un análisis de todos los tuits dirigidos a diario Sur durante la semana previa y primera semana desde la puesta en marcha de su muro de pago, la incidencia y reacción que generó esta medida entre sus lectores. Los resultados revelan que este asunto tuvo una incidencia moderada respecto a la interacción total, aunque la mayoría de los lectores muestran un rechazo (casi) unánime a la implantación del muro de pago. Este estudio invita a la reflexión sobre las demandas de los lectores, quienes usan las redes sociales como una vía para interactuar con los medios.
Nonlinear Mathematical Modelling of Bone Damage and Remodelling Behaviour in Human Femur
Authors: Bu Rui , Qu Chuanyong , Sánchez Yolanda Guerrero
Published: March 2021

The simulation of bone remodelling is highly complex due to the high nonlinear coupled relations between the damage and repair behaviours. In this paper, a new bone remodelling model based on the fatigue damage mechanism is proposed. Then the repair process of the human femur is simulated based on the finite element method. The results show that the new damage model can well simulate the bone damage evolution caused by overloadings. This indicates that the new mathematical model suggested in this paper can simulate the effect of external load on the cortical bone density and the related mechanical properties of the cortical bone.

Published: March 2021

Textile and clothing sector possesses a significant place in Turkish manufacturing industry as well as in exports, investments, gross national product and employment; also maintains its locomotive sector position in development for a long time with its established production potential and labor force. However, there are serious issues about the unionization of workers in the sector. On one hand, this situation causes an increment in social and economical issues of workers and enterprises and on the other hand, it damages democracy within the enterprise. In this context, this study aims to suggest tangible solutions by revealing the economical and social differences between unionization and non-unionization in the sector. Besides, the study differs from other studies and contributes to the literature due to its two-sided research structure (workers and employers) and analysis of unionization in textile and clothing sector in terms of economical and social aspects. In accordance with the aim of the research, two separate surveys are conducted for textile and clothing enterprises, which operate throughout Turkey, and for unionized and non-unionized blue-collar workers of these enterprises. The obtained data are analyzed by using descriptive statistics, exploratory factor analysis, and independent samples t-test. As stated by the research results, the perspectives of unionized and non-unionized participants differ with regard to positive and negative aspects (both economical and social aspects) of being a union member.

On the Forms and Thorns of Linguistic Indeterminacy in Chinese Law
Authors: Mannoni Michele
Published: March 2021

This study addresses the different types and implications of linguistic indeterminacy in Chinese law. It firstly draws on the studies of scholars of different disciplines, such as linguistics and philosophy of language, to provide a taxonomy of indeterminacy in language. It then provides examples of each type, highlighting the implications in law and legal interpretation. It uses linguistic data from various texts, such as statutory laws and judgements, and analyses them with various methods, including discourse analysis and corpus linguistics. This study argues that when the language of the law is indeterminate, the legal outcomes may be particularly uncertain. It suggests that although it is difficult to ascertain whether the degree of indeterminacy is higher in some languages more than in others, some linguistic mechanisms at the word-formation level in Chinese, such as portmanteaus and the modifier-modified structure, are remarkably ambiguous. When uncertain terms are in key parts of the law, the consequences may be more serious. The study of linguistic indeterminacy in Chinese has implications for the study of forensic linguistics, and Chinese studies in general.

Smoking is the most lethal social poisoning event. The World Health Organization defines smoking as the most important preventable cause of disease. Around 4.9 million people worldwide die from smoking every year. In order to analysis this matter, we aim to investigate an e-cigarette smoking model with Atangana-Baleanu fractional derivative. We obtain the existence conditions of the solution for this fractional model utilizing fixed-point theory. After giving existence conditions, the uniqueness of the solution is proved. Finally, to show the effect of the Atangana-Baleanu fractional derivative on the model, we give some numerical results supported by illustrative graphics.
The need for a coordinated action to elucidate ecological occurrence and functions of endophytic fungal communities
Authors: Nicoletti Rosario , Vinale Francesco
Published: March 2021

Research concerning endophytic fungi has recently received a remarkable boost following a general trend to investigate and exploit biodiversity in all its forms, and because of the easier access to equipment and methods, which enables quicker identification procedures. The available data highlight that, besides the plant hosts, endophytes consistently interact with the other components of biocoenosis, and that the assortment of the microbial consortium is also to be considered on account of the reciprocal influence between the several species which are part of it. Unravelling these complex ecological relationships is fundamental because of possible translational applications, particularly regarding crop management. However, this requires that the available information concerning plant species, ecological contexts or functional categories of endophytes is examined fully. In this aim, a coordinated effort appears to be necessary to organise the current knowledge to increase the significance and the practical impact of new findings.

Published: March 2021

It is important to consider the use of the epigenome as source of complementary data for genome knowledge, which is suitable for the diagnosis of schistosomiasis. Usually, a laboratory diagnosis of schistosomiasis is performed by means of 1. Egg detection in the stool or urine by microscopy remains with limited sensitivity; 2. Immunological screening, in which positivity persists after treatment, and 3. Molecular appraisals prevail over the disadvantages of the currently used methods. In this sense, molecular methodologies are being developed based on epigenetic biomarkers, aiming to improve the diagnosis of the disease and clinical treatment as early as possible to prevent the occurrence of serious liver damage.
The Effect of Thermal Modulation on Double Diffusive Convection in the Presence of Applied Magnetic Field and Internal Heat Source
Authors: Manjula S.H. , Suresh P. , Rao M.G.
Published: March 2021

The investigation of thermal modulation on double-diffusive stationary convection in the presence of an applied magnetic field and internal heating is carried out. A weakly nonlinear stability analysis has been performed using the finite-amplitude Ginzburg-Landau model. This finite amplitude of convection is obtained at the third order of the system. The study considers three different forms of temperature modulations. OPM-out of phase modulation, LBMO-lower boundary modulation, IPM-in phase modulation. The finite-amplitude is a function of amplitude δT, frequency ω and the phase difference θ. The effects of δT and ω on heat/mass transports have been analyzed and depicted graphically. The study shows that heat/mass transports can be controlled effectively by thermal modulation. Further, it is found that the internal Rayleigh number Ri enhances heat transfer and reduces the mass transfer in the system.

In this paper, a methodology is presented for determining the stress and strain in structural concrete sections, also, for estimating the ultimate combination of axial forces and bending moments that produce failure. The structural concrete member may have a cross-section with an arbitrary configuration, the concrete region may consist of a set of subregions having different characteristics (i.e., different grades of concretes, or initially identical, but working with different stress-strain diagrams due to the effect of indirect reinforcement or the effect of confinement, etc.). This methodology is considering the tensile strain softening and tension stiffening of concrete in addition to the tension stiffening of steel bars due to the tensile resistance of the surrounding concrete layer. A comparison of experimental and numerical data indicates that the results, obtained based on this methodology, are highly reliable and highly informative.
Competitive spirit as a form of behavioral addiction: the case study of Michael Jordan
Authors: Jacheć Tomasz
Published: March 2021

When studying biographical narratives constituting “The Michael Jordan Myth,” certain patterns emerge. For example, it is possible to identify mythemes corresponding with Campbell’s concept of the hero’s journey monomyth. This study focuses on a particular pattern, which is a progression of addiction with its phases, axial points, and list of symptoms. One of the most frequently used epithets in regard to the hero of this particular myth is “competitive.” While this is a quality of numerous outstanding athletes, in Jordan’s case competitiveness appears as a dominant quality and a driving force throughout his entire career.

The premise of my study is the assumption that Jordan’s competitive spirit is a symptom of behavioral addiction and winning/defeating rivals is the behavior of an addict. The goal of the study is to use Jordan’s biographies and, based on Jellinek’s model of addiction progression, to verify whether Jordan’s accomplishments on and off the court can be viewed as symptoms of unclassified behavioral addiction.

Sepiolite and the sepiolite-based materials were studied in terms of carbon dioxide adsorption. The pore structure and the surface characterization of the obtained materials were specified based on adsorption-desorption isotherms of nitrogen measured at –196oC and carbon dioxide at 0oC. The specific surface area (SSA) was calculated according to the BET equation. The pore volume was estimated using the DFT method. Pristine sepiolite has shown the following value of SSA and CO2 uptake at 0oC – 105 m2/g and 0.27 mmol/g, respectively. The highest value of these parameters was found for material obtained by KOH activation of mixture sepiolite and molasses (MSEP2) – 676 m2/g and 1.49 mmol/g. Sample MSEP2 also indicated the highest value of total pore volume and micropores volume with a diameter up to 0.8 nm.

Background

Ovarian cancer is the seventh most common cancer in women worldwide and the eighth most common cause of cancer death. Due to the lack of effective early detection strategies and the unspecific onset of symptoms, it is diagnosed at an advanced stage in 75% of cases. The cancer antigen (CA) 125 is used as a prognostic marker and its level is elevated in more than 85% of women with advanced stages of epithelial ovarian cancer (EOC). The standard treatment is primary debulking surgery (PDS) followed by adjuvant chemotherapy (ACT), but the later approach is neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS). Several studies have been conducted to find out whether preoperative CA-125 serum levels influence treatment choice, surgical resection and survival outcome. The aim of our study was to analyse experience of single institution as Cancer comprehensive center with preoperative usefulness of CA-125.

Patients and methods

At the Institute of Oncology Ljubljana a retrospective analysis of 253 women with stage FIGO IIIC and IV ovarian cancer was conducted. Women were divided into two groups based on their primary treatment. The first group was the NACT group (215 women) and the second the PDS group (38 women). The differences in patient characteristics were compared using the Chi-square test and ANOVA and the Kaplan-Meier method was used for calculating progression-free survival (PFS) and overall survival (OS).

Results

The median serum CA-125 level was higher in the NACT group than in the PDS group, 972 IU/ml and 499 IU/ ml, respectively. The PFS in the NACT group was 8 months (95% CI 6.4–9.5) and 18 months (95% CI 12.5–23.4) in the PDS group. The median OS was lower in the NACT group than in the PDS group, 25 months (95% CI 20.6–29.5) and 46 months (95% CI 32.9–62.1), respectively.

Conclusions

Preoperative CA-125 cut off value of 500 IU/ml is a promising threshold to predict a successful PDS.
Does Renewable Energy Matter for Economic Growth in Central and Eastern European Countries? Empirical Evidence from Heterogeneous Panel Cointegration Analysis
Authors: Neagu Olimpia , Haiduc Cristian , Anghelina Andrei
Published: March 2021

The aim of the paper is to provide empirical evidence in support of the relationship between renewable energy consumption and economic growth in eleven Central and Eastern European (CEE) countries over the period 1995-2015 within a multivariate panel data analysis. Based on World Bank data, the panel cointegration analysis reveals that renewable energy consumption and economic growth are positively associated in the long run in CEE countries. The heterogeneous panel causality test indicates a bi-directional causality relationship in support of the feedback hypothesis between economic growth and renewable energy consumption in Central and Eastern European countries.
Inventory Routing Analysis for Maritime LNG Supply of German Ports
Authors: Prause Felix , Prause Gunnar
Published: March 2021

After the implementation of Emission Control Areas (ECA) in Northern Europe in 2015, ship operators have to decide for new compliance methods. Among different abatement technologies, also the use of LNG as maritime fuel is one option. Hence, the number of LNG-fueled vessels plying in North Sea and Baltic Sea is growing, so ports have to cope with the increasing demand for LNG. Until now, German ports have been a little bit delayed in the installation of LNG infrastructure. Currently, a new LNG-terminal at Brunsbüttel, the western entrance to the Kiel Canal, is under construction.

The distribution of LNG from the new LNG-hub to the other German ports can be modelled as an Inventory Routing Problem (IRP) that is usually solved by combinatorial optimization methods. This paper investigates the research question, how the distribution can be modeled as an IRP, which distribution mode is the most economic for the German ports and which modal mix for the LNG supply leads to the greenest distribution. The results of this paper are empirically validated by data that were collected in several EU-projects on sustainable supply chain management and green logistics.
Nudges: diseño y evaluación
Authors: Costas-Pérez Elena , Tucat Pablo
Published: March 2021

La literatura sobre nudges y su evaluación es extensa, y destaca la diversidad de sesgos de comportamiento y posibles intervenciones. Los nudges buscan modificar la arquitectura de las decisiones individuales, intentando cambiar el comportamiento de las personas en una dirección concreta y a un bajo coste. Su impacto debe tener en cuenta el coste-efectividad del dinero invertido, en comparación a otras intervenciones públicas más tradicionales que persiguen el mismo objetivo. El uso de experimentos en su evaluación ha convertido a los nudges en una importante herramienta de la política basada en la evidencia, mejorando así el diseño y efectividad de la acción pública. En este artículo buscamos revisar el conocimiento actual en torno al diseño y evaluación de los nudges, y su importancia para el desarrollo de políticas basadas en evidencia.
