The Great Recession: on the Ineffectiveness of Domestic Policies and the Need of Multilateral Arrangements
Authors: Rojas Jorge
Published: March 2023

The Great Recession is the manifestation of some fundamental problems in the real sector of the global economy, related basically to the loss of competitiveness of the U.S. and other central economies, reflected in continuous external disequilibria in the form of parallel current account deficits and financial account surpluses. Domestic monetary and fiscal (or domestic adjustment) policies have not reached a solution to the problem because we are now dealing with a global problem that requires multilateral solutions seeking to adjust some fundamental relative prices and the closing of some key structural imbalances in order to make a sustainable recovery possible. Besides, the difficulties in finding and engineering a solution show the need to reassess the theoretical paradigms underlying the economic policies that preceded the current crisis (e.g., supply-side economics).

El objetivo de este artículo es analizar qué determina que los jóvenes que aún viven en la casa de sus padres se encuentren estudiando, trabajando, combinado ambas actividades, o fuera del sistema educativo y de la fuerza laboral. Nos interesa determinar qué mantiene a los jóvenes en el sistema educativo, aun si están trabajando, y si existen diferencias por género. Partimos de un modelo de negociación cooperativa eficiente entre los padres y el joven, y estimamos una regresión Logit Multinomial con datos del Perú Urbano para el año 2014. Encontramos que los jóvenes se mantendrán en el sistema educativo aun si están trabajando, mientras mayor sea su poder de negociación en el hogar, menor su costo de oportunidad, y más años de estudios tengan sus padres.
Tres cineastas regionales del sur andino en el campo cinematográfico peruano
Authors: Gutiérrez Gonzalo
Published: March 2023

El objetivo principal de este artículo es brindar un panorama general sobre el llamado cine regional peruano. En particular, se define una lógica del campo cinematográfico en el Perú y se busca ubicar allí a tres cineastas regionales del sur andino: Jacqueline Riveros (Huancayo), Jaime Huamán (Abancay) y Flaviano Quispe (Juliaca). Ahora bien, ¿en qué consisten y de qué manera ocurren estas luchas por la legitimidad en el campo cinematográfico peruano? Esta investigación sostiene que uno de los factores que determina las luchas por la legitimidad en el campo cinematográfico es el origen sociocultural y las condiciones (adversas) de los cineastas regionales en el campo cinematográfico peruano. Estos son examinados en relación con categorías y conceptos trabajados desde la sociología de la cultura; en particular, por los autores Pierre Bourdieu y Néstor García Canclini, y desde un enfoque metodológico cualitativo. Los hallazgos sustanciales giran en torno a la perspectiva con la que se aborda el problema en cuestión. La escasa literatura respecto del cine regional peruano ha optado en buena cuenta por enfoques de comunicación descriptiva, o por el análisis de discurso y contenido de las representaciones en los filmes. En el caso de este artículo, se opta por centrarse en los propios actores (los cineastas) e identificar sus objetivos, apuestas, estrategias de posicionamiento y diferentes tensiones en la búsqueda de la legitimidad en el campo referido.

Methods: A total of 2590 insemination including 1776 first time insemination was carried out during the period of 2018-2020 in the Gir cattle distributed in the semi-arid region of RajasthanNRR90F and CR were analysed as binary variable and INS as multi-nominal trait. Generalized linear models were used to for the evaluation of non-genetic factors and generalized linear mixed models for genetic effects. Result: The average success rate of artificial insemination was estimated as 0.35 for NRR90F and 0.41 for CR. Further, cumulative logit link function was used to analyse the number of successful insemination to conception (INS) and cumulative estimates was observed as 0.95 for two number of insemination to conception. Period and season were the non-genetic factors that influenced the traits studied. Decreasing trend was observed over the period for success of insemination for all studied traits. Summer season showed highest odd ratio and estimated as 1.213 for NRR90F, 1.388 for CR and 1.440 for INS with reference to autumn season. Heritability was estimated as 0.015 for NRR90F, 0.028 for CR and 0.086 for INS.
Field Performance of Some Soybean [Glycine max (L.) Merr.] Cultivars Sown on Different Dates
Authors: IZGI M. Necat
Published: March 2023

Soybean [Glycine max (L.) Merr.], with high oil and protein content, is one of the world's main nutritional sources and millions of hectares are given over to its cultivation. Intensive farming and producing multiple crops per year (such as second-crop soybean cultivation), can improve natural resource exploitation and productivity. The objective of this study was to examine the effects of some soybean cultivars on yield and yield components in lowland conditions in the Mardin province over the main-crop and second-crop seasons. This research was carried out in the lowland conditions of Mardin province in Türkiye in 2018 and 2019. The A-3127, Arısoy, Ataem-7, Blaze, Bravo, Cinsoy, Gapsoy-16, Lider, May-5312, Nova, SA-88, and Umut-2002 cultivars were used as plant material in this research. Since the region is suitable for growing double crops per year, soybean field trials were carried out both as a main crop and as a second-cropped. Sowing dates and 12 different soybean cultivars were taken as factors in the research. The first sowing took place on April 16, the second on April 25, the third on June 15, and the fourth on June 30 in both years of the research. Two sowings were the main crop, while the other two were second-crop. According to the results, the A-3127 (3700 kg ha-1) and Gapsoy-16 (3694 kg ha-1) cultivars produced the highest seed yield. The Arısoy (676 kg ha-1), Gapsoy-16 (676 kg ha-1), A-3127 (662 kg ha-1), and Cinsoy (662 kg ha-1) cultivars produced the most oil yield. The study determined that early sowing increases overall yield while late sowing decreases seed yield significantly (on average by 30%). For this region and in areas with similar agricultural environments where double-crop can be grown each year, early cultivars for a second crop may be recommended to reduce the vegetable food and oil deficit.

Authors: Danang Kumara Hadi  , Assadam Ahib , Widianto Zidan Eka , Renadi Berino
Published: March 2023

Industrial developments and increasing consumer concern for the environment and the issue of environmentally sound industrial concepts have forced the industry to adjust the concept of green industries in every business, including in procurement, which is better known as green procurement. Supplier selection is an important decision-making problem to get suppliers who can increase the company's competitiveness. This research was conducted in Jember regency to evaluate and select cassava suppliers based on green procurement using the AHP method. The criteria used are 6 criteria, namely quality, technology capability, pollution control, environment management, green product, and green competence. Each criterion has sub-criteria between 3 or 4 sub-criteria. The number of sub criteria is used to determine the RI value. The RI value is used to calculate the CR value of each criterion. The results of data processing show that the highest CR value is in the technology capability criteria and the lowest CR value is in environment management. The highest hierarchical criterion value for environmental management criteria is 0.273, because the selection of cassava suppliers can be expected to pay attention to environmentally sound controls.

It is possible to determine a service life of an electric-multiple unit and its assemblies by actual time of proper operation or theoretically according to results of comprehensive test of components and parts. According to standards of car calculation on strength, for parts that work in conditions of long and intense influence of dynamic loads it is necessary to determine fatigue strength at multi-cycle loading. Calculation is carried out with the consideration for probabilistic dispersion of fatigue strength characteristics and stochasticity of dynamic loading of a part, on the basis of which a life cycle is determined. Oscillograms of dynamic processes gained at tests on the line in theoretical calculations are substituted by a number of simple cycles. Study results presented in the paper allow determining static and dynamic parameters of springs of the primary spring suspension for electric-multiple unit bogie and a type of a simple cycle and its parameters.

The paper considers a problem of a real speed of movement of city residents on the example of Ekaterinburg. Comparison of various types of municipal passenger transport is usually reduced to assessment of cruising speed on a route. However, speed of passenger movement depends not only on the transport used, but on distance of a trip and distance of pedestrian approaches to stops of public transport. Besides, real speed depends on a headtime between consecutive vehicles on a route.

A method of comparative assessment of the influence of the features of dynamic interaction in the «block wheel-set - rail track» system on the wear rate of the rolling surfaces of wheels, axle bearings, and the support of the freight car bogie due to new design solutions implemented in the block wheelset is presented. A block wheelset differs from a typical pair in that it has separated the functions of holding and directing movement (ridge) and ensuring the movement of the wheelset in a straight section of the track (straight and winding). In the process of simulation modeling of interaction of block and standard wheel pairs with the rail track, the parameters of this interaction (motion trajectories, wave-lengths and their amplitudes) are established. As an external disturbance in the mathematical model of the dynamic system «wheelset - track», geometric deviations of the rail track obtained under real operating conditions of main lines were used. The comparative calculated assessment of the levels of wear intensity of the rolling surfaces of the support wheel of the block and standard wheel pairs was carried out according to the developed methodology of a specific comparative indicator - the coefficient of the energy factor of wear. The resource of the bogie pivot bearing with block wheel pairs increases due to the growth in the wagging wavelength by six times compared to the typical wheel pairs, that is, the friction path in the «pivot bearing-axle bearing» component from a typical wheel pair increased proportionally.

In railway transport, the response time to abnormal and emergency situations, including acts of unlawful interference, is a very significant parameter that determines the level of safety. The reason is the direct dependence of the response time and the amount of damage from the incident. The speed of processing and transmission of incident data by the involved official is a parameter that determines the response time. Increasing this speed will reduce the response time and, as a result, reduce the damage caused. The paper considers the implementation of a simulation model that studies the response of structural units of subsystems for ensuring safety on the railway. The model was developed using MatLAB application programs. Response is a sequence of notification of officials involved in the elimination of abnormal and emergency situations on the railway and ensuring the safety of its operation. Officials of the response system are represented by multiphase links. The links reproduce the processes of receiving, processing and transmitting information about the incident. The link architecture takes into account the technical capabilities of communication systems to handle the call flow. The paper also reflects the basic rules of functioning of the simulation model and presents the interface of a software product that automates the process of obtaining simulation results.
Development of linguistic communicative competence of students of the Transport University in English classroom through the use of professionally-oriented texts
Authors:   Ural state university of railway transport (USURT), Lopatin M. A.
Published: March 2023

In accordance with the current foreign language program for non-linguistic universities, training of future specialists in a foreign language should be professionally oriented. Special emphasis is placed on implementation of the transition from learning a foreign language as an academic discipline to its practical use for professional purposes, since this is the main task of the program. Modern graduates should have professional and communicative competence, which is a necessary quality for subsequent effective professional activity, which will require them to speak a foreign language within the framework of professional communication. This may include reading special original texts, participating in discussions, presentations, and situations of scientific and professional communication in a foreign language. Professionally-oriented foreign language teaching means education, the essence of which is its integration with the core disciplines and can be considered as a means of improving professional competence and personal and professional development of students. Professionally-oriented teaching of a foreign language implies, first of all, the professional orientation of the content of educational materials, as well as activities containing techniques for the formation of professional phenomena. Future engineers and scientists can acquire extensive modern knowledge in English classes in order to get acquainted with the results of the latest research and achievements in the field of science and technology. Reading in this case becomes the main way of obtaining such information. Therefore, we can say that reading in transport universities is both a tool and a goal of teaching a foreign language. In this paper, we tried to consider the need to develop reading skills of specialized literature for students of transport universities and to determine the role of reading in the process of teaching/learning English. We look upon professionally-oriented foreign language teaching as part of teaching students of railway specialties of the Ural State University of Railway Transport to read special authentic texts. The main criteria for the selection of authentic texts for professionally oriented reading, methodological approaches to organization, presentation of the text material and the most effective methods of working with such texts are considered. Practical examples of tasks are presented when working on a text, with the use of a communicative approach in teaching as a priority. The statement about the importance of teaching reading texts in the specialty, facilitating to develop the professional and communicative competence of students, is grounded.

Published: March 2023

Limiting the mobility of urban residents during the COVID-19 pandemic (April, May, June 2020 - the full lockdown; other periods of 2020-2022 - the limited lockdowns) became a serious test for urban public transport management systems (UPT). The collapse in demand for UPT services from the citizens caused a managerial attempt to build the carrying capacity of the transport system in order to find a new level of supply-demand balance. On the example of the UPT system in Tyumen, the issues of the quality of such managerial adjustment and methodology for quantitative assessment of the transportation process stability during the first year of the COVID-19 life cycle are considered.

Assessment of the strength of structures, machines and mechanisms. Analysis of methods and ways of improvement
Authors:   Ural state university of railway transport (USURT), Antropova Tatiana A.
Published: March 2023

The article analyzes the existing approaches to calculation of structural strength: deterministic and statistical. The method of approaches allows us to study the change in mechanical characteristics, to determine the safety margin of the part, which depends on these characteristics. Both methods are quite extensive studies, and the processing of results has a number of conditional assumptions. It is established that these approaches do not allow to take into account to full extent the random nature of occurrence of a number of parameters of machines, mechanisms and their parts. It is proposed to improve the methodology for calculating structural elements for strength, using an integrated approach which takes into consideration the random distribution of initial data.

Formulation of a radiological scoring system to prognosticate patients with primary intracerebral haemorrhage
Authors: Kumar Krishna , Gopalan Harison , Jayaprakash Jayalakshmi
Published: March 2023

Background. Primary intracerebral haemorrhage is a neurological condition associated with high morbidity and mortality. Outcome prediction is necessary to allocate the available resources in such cases judicially. Our study aims to identify the radiological predictors of in-hospital mortality based on a plain CT study of the brain at admission and to develop a prognostic scoring system based on them. Material and methods. We collected the clinical and radiological data from 182 consecutive patients who presented with primary spontaneous ICH. Bivariate analysis of radiological predictors of in-hospital mortality was undertaken using unadjusted logistic regression. Those variables found to have significance were put into a multivariate logistic regression model. The Results of multivariate logistic regression were treated as a foundation for developing the scoring system.   Results. The mortality rate in our series was 23.6% (N = 43). After multivariate analysis, Midline shift (MLS), presence or absence of intraventricular haemorrhage (IVH), Volume of ICH and Location of haematoma were significant predictors of mortality. Based on the identified radiological variables, a five-score prognostic scoring system (AUROC = 0.925, 95% CI 0.887–0.964)) was developed, with higher scores indicating higher mortality. Conclusions. The established scoring system, MIVL, may help physicians to do better patient counselling regarding outcomes.

A revolução anarquista ibérica noventa anos atrás: uma experiência única e irrepetível?
Authors: Solà i Gussinyer Pere
Published: March 2023

Por que um poderoso movimento anarquista não renasceu na Catalunha e na Espanha na transição da chamada "sociedade de bem-estar" para o neoliberalismo? Por um momento, parece que as coisas poderiam ser diferentes. Nos territórios da língua catalã e na Espanha pós-franquista, mas mesmo franquista, a primavera libertária dos anos setenta foi frustrada. Não há possibilidade objetiva de emendar com o que tinha sido o movimento de massas anarco-sindicalista das primeiras décadas do século. Este artigo de Pere Solà enfoca vários dos fatores do eclipse da perspectiva libertária no Estado espanhol desde os anos setenta. Tal eclipse choca com uma tendência internacional de considerar que a anarquia, o modo de pensar e viver que proclama a liberdade individual e a igualdade coletiva, desperta um renovado interesse na esfera cultural, política, filosófica e educacional. A questão do poder e da violência a partir da perspectiva democrática voltou a ficar em primeiro plano, ecoando reflexões clássicas como as de Noam Chomsky e outras contemporâneas, como as dos filósofos Cathérine Malabou ou Giorgio Agamben.

Child Marriage: A Blow to Human Dignity and Women’s Liberty
Authors: Das Madhushree
Published: March 2023

The current editorial discusses child marriage, a human rights violation and a chronic problem across India. Despite several laws and acts against the practice, and recent arrests made in Assam, India, the problem still persists and has been found to be dominant in the rural areas, among poor families with lower education levels. This study makes an attempt to deliberate upon various reasons leading to child marriage and the implications of child marriage which is negatively affecting the health and well–being of women and children, thereby triggering the maternal and infant mortality rate across the country. The study stresses that to achieve the target set by Sustainable Development Goal 5.3 on gender equality to eliminate child marriage by 2030, effective interventions from all quarters, along with stringent laws and proper policies are essential.
Roosting and breeding behaviour of Tawny Frogmouths Podargus strigoides in central-coastal Queensland
Authors:   BirdLife Capricornia, 192 Palm Valley Road, Coowonga QLD 4702, Australia, Briggs Allan
Published: March 2023

The roosting and breeding behaviour of a pair of Tawny Frogmouths Podargus strigoides was observed on the central Queensland coast over a period of 4 years (2018–2021). The study was conducted in a subtropical climate near Rockhampton, and provides data from a different geographical and climatic area compared with previous studies that were conducted in temperate southern Australia (New England Tablelands, Moree, and Sydney, New South Wales, and the Australian Capital Territory). Breeding data matched other studies: breeding in November–December, incubation of 28–30 days, fledging at 27–31 days, care of fledglings from 1–3 months, nests located in a horizontal fork of a tree on the edge of a clearing. Breeding success was high at 80% (8 of 10 nestlings survived). Roost sites were generally in tree species with a fibrous dark bark that provided camouflage, and were mostly within the leafy canopy (average height 9.11 m above ground), which provided protection from high daytime temperatures in both winter and summer. Only early in the morning on very cool days in winter did Frogmouths seek lower perches where sun exposure was greatest. These findings are consistent with other studies identifying thermoregulation and camouflage as important determinants of roost selection, although the need for greater sun exposure in winter was much lower in this study, reflecting the generally warm winter days. Fidelity to roost trees was high (90% of roosts were in four trees) and Frogmouths nested in a different tree each year. Both roosts and nests were confined to a home range of 1.6 ha. The frequency of feeding increased with nestling age, and was higher during the early part of the night. Overall, these findings advance understanding of the breeding biology of the Tawny Frogmouth in subtropical Australia.
Time Crystals, Their Networks, and Self-Organized Vacuum
Authors: Manasson Vladimir A.
Published: March 2023

The phenomenon of dissipative self-organization is studied on the example of time-crystal networks. Par-ticular attention was given to transient processes, attractor topologies, phase transitions, and asymptotic stability. New concepts were introduced, including topological phases, spinorial states, and bond flavors. Concepts such as ground states, chemical potentials, elastic forces, temperature, and statistical distribu-tions were endowed with a new meaning associated with asymptotic stability. Phenomena usually at-tributed exclusively to quantum physics have been shown to occur in this essentially classical environment. They coexist with, and in some cases, such as charge quantization, are related to the phenomenon of time dilation. The approach was applied to model vacuum self-organization. We have shown that under the ac-tion of competing forces, such as gravity and antigravity, a cascade of phase transitions can transform an unorganized vacuum into phases in which interactions, fields and waves resemble electromagnetic, weak, and strong, and their elements can be used as building blocks for prototype particles. In addition, some interrelation field parameters and probabilities of particle transmutations were calculated, which are not predicted by the standard model. The results are consistent with the experiment. The presented material and methodology may be of interest for studying self-organization in different environments.

Social media has revolutionized the way we communicate and interact with each other. While it has brought many benefits, it has also presented many ethical challenges. Social media platforms have access to an enormous amount of personal data, and there are concerns about how this data is being stored, collected, and used. Users often need to fully understand the risks of sharing sensitive information. Social media platforms have made it easy for fake news to spread rapidly, which can be dangerous and have serious consequences. Misinformation and propaganda can influence people's decisions and beliefs. In this paper, we will analyze the issues and challenges that may arise, and it will be necessary for individuals and society to address these challenges ethically and responsibly.
