Residential-Based Discrimination in the Labor Market
Authors: Mikula Štěpán , Reggiani Tommaso 
Published: April 2022

Abstract
Through a correspondence study, this paper investigates whether employers discriminate job applicants based on their living conditions. Exploiting the natural setting provided by a Rapid Re-housing Program, we sent 1347 job applications for low-qualified front-desk jobs in Brno, Czech Republic. The resumes exogenously differed in only one main aspect represented by the address of the applicants, signaling both the quality of the neighborhood and the quality of the housing conditions in which they were living. We found that while the higher quality of the district has a strong effect in increasing the hiring chances (+20%) the actual improvement of the living conditions standards, per se, does not generate any significant positive effect.
Scalar and vector tomography for the weighted transport equation with application to helioseismology
Authors: Thompson Nathan L. , Bukhgeim Alexander L. 
Published: April 2022

Abstract
Motivated by the application to helioseismology, we demonstrate uniqueness and stability for a class of inverse problems of the weighted transport equation.
Using 𝐴-analytic functions, this inverse problem is expressed as a Cauchy problem.
In this form, we show that, for a finite even trigonometric polynomial weight function, the resulting system is well-conditioned numerically and permits a Carleman-like estimate with boundary terms.
Education and employment in America: my quest for self-actualization as a person with hearing loss
Authors: Eleweke C. Jonah 
Published: April 2022

Abstract
Evidence indicates that some Africans, with or without special needs or disabilities highly target attending U.S. colleges and universities for further education. Typically, most of these people had obtained their bachelor’s degrees in institutions of higher education in their countries. The desire to travel to U.S. for graduate studies could be due to factors such as the absence of desired graduate programs, limited admission opportunities in institutions of higher education, and social, political, and economic instabilities in African countries. For Africans with special needs or disabilities, the lack of support services in tertiary institutions in their countries is a major factor for their strong desire to go the U.S. for higher education. Some Africans educated in U.S. colleges and universities may, on completion of their programs of study, decide to seek suitable employment opportunities in the U.S. From afar, they are still able to make positive contributions to the social, economic, and political developments of their home countries. I am one of those graduates who decided to work in the U.S. In this article, I share my experiences.
Dual-band composite right/left-handed metamaterial lines with dynamically controllable nonreciprocal phase shift proportional to operating frequency
Authors: Kaneda Takumi , Ueda Tetsuya 
Published: April 2022

Abstract
Dual-band composite right/left-handed transmission lines with the nonreciprocal phase shift approximately proportional to the operating frequency are proposed and demonstrated by using normally magnetized ferrite microstrip lines. The nonreciprocal phase shift can be dynamically controlled by changing the externally applied dc magnetic field. Dynamic change in the nonreciprocal phase gradient along the line enables us to realize dual-band and unidirectional beam-scanning leaky-wave antennas without suffering from frequency-dependent change in the beam direction. A prototype nonreciprocal metamaterial line using polycrystalline yttrium iron garnet was fabricated and measured for verification of our basic concept.
Influence of irrigation regime on gas exchange, growth, and oil quality of field grown, Texas (USA) olive trees
Authors: Parks Staci , Montague Thayne 
Published: April 2022

Abstract
Olive (Olea europaea L.) oil production is an emerging industry in Texas (USA). However, limited research has been conducted to determine best irrigation practices for Texas growers. In this study, established “Arbequina” olive trees from three south Texas orchard locations were used to investigate effects of irrigation volume on olive tree gas exchange, growth, and oil quality. Twelve-year-old trees were exposed to three irrigation regimes. Over the course of two growing seasons, leaf gas exchange, shoot growth, and oil quality were measured. Data from a single orchard and growing season are presented. Differences in monthly and overall leaf gas exchange data were not found. Based on soil surface area under each tree’s dripline, depth of total water applied to each tree (irrigation plus precipitation) ranged from 1,451 (three-emitter irrigation treatment) to 759 mm (one-emitter irrigation treatment). Trees exposed to the three-emitter irrigation treatment produced the greatest shoot growth. Fruit mass and fruit volume were greatest for trees which had the fewest emitters (lowest irrigation volumes). Oil pressed from each experimental tree rendered extra virgin olive oil. Oil chemical analysis indicates total phenols tended to be greatest from trees receiving the least volume of irrigation. For Texas olive growers, research suggests there are opportunities to reduce irrigation, yet maintain olive oil quality.
The Coronavirus and the Earth’s Thinking: An Anthropological Issue
Authors: Quiroga Tiago 
Published: April 2022

Abstract
The article develops the hypothesis that Covid-19 is one of the most significant results of the Anthropocene era. Indifferent to nature’s veiled, but not inactive conditions, the human era advances over woods and forests, intensifying the increase of emerging infectious diseases, especially those caused by pathogens that generate zoonoses. In addition to health matters, this circumstance implies the urgent revision of the cultural tradition that conceives the energies of nature as availability. Based on these findings, the text criticizes the cultural determination of anthropocentrism, suggesting that the crisis caused by the coronavirus also represents the possibility of new mediations with nature. The thesis defends that, despite the anguish caused by the proximity to death, the pandemic is an opportunity to open our ears anew to listen to the Earth’s thinking.
The Social Background of the Enlightenment in Russia in a Comparative Perspective
Authors: Artemyeva Tatiana V. 
Published: April 2022

SummaryThe Age of Enlightenment is identified as an eighteenth-century intellectual and philosophical movement that produced a variety of ideas ranging from the conservative to the radical, and from rational to mystical or even counter-enlightenment. This article discusses the social structure of intellectual elites in different countries during the Enlightenment. It argues that the different systems of ideas that were generated during this period, and the different forms these ideas took, are a result of the different configurations of intellectual elites in each country. It turns to examples from Scotland, France, German lands, and Russia to show the social background of enlightenment ideas.
Zum 100. Geburtstag von Igor’ Cholin: Die Werkauswahl der Edition Aspei (Bochum) zwischen Avantgarde und Konzeptualismus
Authors: Hofmann Tatjana 
Published: April 2022

Summary
The following article was originally meant to be a review of the German Cholin edition. During my correspondence with the editors the text developed in dependence on my reception process: I started to read Cholin in an intertextual chain of (post-)avant-garde art and life practices that are situated around documentarism. Cholin’s poetics builds upon language experiments of Zaumniki and the absurd writing of Obėriu. Besides, I argue, we can also find some references to the simultaneously emerged, yet contrary avant-gardistic movement of Factography. Cholin’s mediators reinforce this tradition as they set in motion the continuation of the factographic discourse via Moscow Conceptualism and its reception aesthetics in (Western) Germany and in Western Europe. The edition by aspei applies practices of publishing, translating and researching next to artistic ones, thus integrating documenting as well as commenting.
Translationally invariant exact steady flows of gas and fluid
Authors: Bogoyavlenskij Oleg 
Published: April 2022

Abstract
New exact 3-D steady translationally invariant (or z-invariant) flows of isentropic gas and ideal incompressible fluid are constructed. New exact solutions for steady magnetohydrodynamics equations are derived. We show that Euler equations for steady z-invariant flows of isentropic gas are equivalent to a coupled system of a partial differential equation of second order for the streamfunction ψ(x, y) which contains an arbitrary differentiable function H(ψ) and a transcendental equation connecting gas density ρ(x, y) with function ψ(x, y) and depending on equation of state p(ρ) = cρ

γ
and on the function H(ψ). We prove that functions ψ(x, y) and ρ(x, y) satisfy a universal nonlinear equation that is independent of equation of state p = p(ρ) and of the function H(ψ).
Similarity solution for one dimensional motion of a magnetized self-gravitating gas with variable density under the absorption of monochromatic radiation
Authors: Sahu Praveen Kumar 
Published: April 2022

Abstract
The impendence of azimuthal or axial magnetism in one-dimensional shock wave prevalence via a gas with monochromatic radiation for cylindrical and spherical geometry is examined. The travelling piston supplies the varying input of energy continuously and conditions of equilibrium flow through the whole field are retained. A regime of ODEs is derived by means of the regime of governing motion’s equations using the similarity process. The distributions of gas-dynamical quantities, obtained by their numerical integration, are discussed through figures. It is observed that the adiabatic index and the impendence of magnetism, as well as gravitation, lessen the shock intensity, however, the initial density variation index has the opposite behaviour on it.
Low but not undetectable early postoperative nadir serum cortisol predicts sustained remission in Cushing’s disease
Authors: Stroud Anna , Dhaliwal Pearl , Harvey Richard J , Alvarado Raquel , Jonker Benjamin P , Winder Mark J , Grayson Jessica W , McCormack Ann 
Published: April 2022

Objective
Transsphenoidal surgery (TSS) is the first-line treatment for Cushing’s disease. The objectives of the study were to determine remission and recurrence rates after TSS for Cushing’s disease, identify factors that predict these outcomes, and define the threshold for postoperative morning serum cortisol (MSeC) that most accurately predicts sustained remission.

Methods
Records were retrospectively reviewed for consecutive adults undergoing TSS for Cushing’s disease at a tertiary centre (1990–2019). Remission was defined as MSeC <138 nmol/L by 6 weeks postoperatively. Recurrence was defined as elevated 24-h urine free cortisol, lack of suppression after dexamethasone or elevated midnight salivary cortisol.

Results
In this study, 42 patients (age 47 ± 13 years, 83% female) were assessed with 55 ± 56 months of follow-up. Remission occurred after 77% of primary (n = 30) and 42% of revision operations (n = 12). After primary surgery, remission was associated with lower MSeC nadir (26 ± 36 nmol/L vs 347 ± 220 nmol/L, P  < 0.01) and lower adrenocorticotropin nadir (2 ± 3 pmol/L vs 6 ± 3 pmol/L, P = 0.01). Sustained remission 5 years after surgery was predicted by MSeC <92 nmol/L within 2 weeks postoperatively (sensitivity 100% and specificity 100%). After revision surgery, remission was predicted by lower MSeC nadir (70 ± 45 nmol/L vs 408 ± 305 nmol/L, P = 0.03), smaller tumour diameter (3 ± 2 mm vs 15 ± 13 mm, P = 0.05) and absence of cavernous sinus invasion (0% vs 71%, P = 0.03). Recurrence after primary and revision surgery occurred in 17% and 20% of patients respectively.

Conclusions
Lower postoperative MSeC nadir strongly predicted remission after both primary and revision surgery. Following primary surgery, an MSeC <92 nmol/L within 2 weeks predicted sustained remission at 5 years. MSeC nadir was the most important prognostic marker following TSS for Cushing’s disease.

Published: April 2022

Gonadectomy (caponization) of cockerels is an important way of increasing their productivity, improving the quality and taste properties of the meat, and obtaining dietary products. The objective of the study was the influence of gonadectomy of cockerels on their clinical condition, morphological composition of blood, hemoglobin content and anabolism in the tissues, their productivity and chemical content of the muscles. In the experiment, we used 30 Adler silver cockerels aged 4 weeks, which were divided into two groups: control (intact) and experimental (gonadectomized) according to the analogue principle, with 15 individuals in each. The experiment lasted for 185 days, including the main period of 175 days. We determined that the body temperature of cockerels after gonadectomy increased as early as days one and three. In the blood of gonadectomized cockerels, the number of leukocytes decreased by 36.3%, thrombocytes – by 24.7%, while hemoglobin concentration, numbers of heterophils, eosinophils, basophils, monocytes and lymphocytes did not change compared with the intact individuals. On days 20 and 185 of the experiment, the concentration of testosterone in the blood plasma of gonadectomized cockerels was lower respectively by 57.1% and 53.1%, whereas no differences were found prior to gonadectomy and on the third day of the experiment. We determined increase in uric acid concentration and decrease in the level of ionizing calcium in blood plasma of gonadectomized cockerels compared with intact individuals, while the content of cortisol, glucose, total protein, triglycerides, cholesterol, total calcium and inorganic phosphorus, and also activities of alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase did not change. Live weight of gonadectomized cockerels in the period from 45 to 105 days of the raising did not change, and was higher by 10.4–17.0% from day 115 to 145, and further remained not different from the control. Thoracic muscles of gonadectomized cockerels contained 1.8 times more fat, while the levels of moisture, dry matter, protein and ash in thoracic and thigh muscles did not change. The conducted studies have revealed the effect of gonadectomy of roosters on clinical-hematological parameters, metabolic processes, productivity of birds and chemical composition of muscles and may be used to improve the production of chicken meat with high dietary and taste properties.

Authors: Zasemkova O. F. 
Published: April 2022

The COVID-19 pandemic that has spread the whole world and the restrictive measures taken to combat it have had an unprecedented impact on all aspects of modern society, including cross-border family relations, and, in particular, situations of international child abduction. One of the most difficult question is the possibility of justifying the refusal to return a child taken to the territory of another country by one parent without the consent of the other, referring to the existence of a grave risk to his life and health (In the context of subparagraph “b”, paragraph 1 of Article 13 of the Hague Convention on the Civil Aspects of International Child Abduction) — the treat of his infliction with a new coronavirus COVID-19 pandemic in the process of his return to the country of habitual residence or a complex epidemiological situation in this country.In this regard, the author tries to answer this question, taking into account the official interpretation of the provisions of the Convention, as well as judicial acts issued by courts of various states. Based on the analysis, the author comes to the conclusion that it is impossible to justify the refusal to return the child by referring to the COVID-19 pandemic.

On Chinese Students’ English Pronunciation Problems and Countermeasures
Authors: Xiao Qinghua , Chen Ming 
Published: April 2022

Phonetic learning is the foundation of foreign language study and it is critical for the development of foreign language
proficiency. Many Chinese students have a poor command of English pronunciation, which often results in unintelligibility and
even misunderstanding in cross-cultural communication. This paper will explore Chinese students’ pronunciation problems from
segmental perspective and suprasegmental perspective, and propose effective countermeasures to cope with the problems.
