The model of tenure choice in life cycle of Poles – empirical analysis
Authors: Matel Anna , Olszewski Krzysztof
Published: December 2022

We analyse tenure choice determinants of Poles for the years 2006, 2010, 2014 and 2018 on EU-SILC data, distinguishing between co-residence with the parents, renting at market rates and owning a house. The average marginal effects obtained from multinomial logistic regressions allows us to conclude that ownership is strongly connected to the family status, but this relationship weakens over time. Unmarried people without children but with better incomes become increasingly more likely to be homeowners. Thus, ownership is not anymore a main domain of conventional families. Moreover, renting becomes an option to become independent for those who cannot afford to buy a house. But it is rather a temporary solution, because renting is more costly than buying a house with a mortgage. We also find evidence of the gender gap in homeownership, as women are more likely to be owners, and less likely to co-reside with their parents than men. Along the evolution of the housing finance system, growing wages make ownership more likely. We observe that the choices are more free in densely populated regions, where the rental market develops. In this part of the paper explain the data that we use, present the empirical results and discuss them.

Authors: Zavatskyi Yuriy , Shapovalova Valentine , Zavatska Natalia , Getta Оlena , Shelest Оlena
Published: December 2022

The article discloses a systematic approach to psychosocial rehabilitation of the individual. The principles of psychosocial rehabilitation include: the feasibility of the tasks set before the rehabilitator - any patient has a huge experience of disappointments, and each new failure actualizes his traumatic experience, therefore it is extremely important to plan tasks that would guarantee the success of the rehabilitator in completing them; providing staff support to the rehabilitator in his feelings and actions related to overcoming difficulties, taking into account the long history of personal and social defeats; tolerance for "strange" behavior: requirements for it are less strict than in normal conditions, except for dangerous forms of behavior; non-reinforcement of negative expectations: employees do not show reactions of disappointment, denial, refusal, punishment expected by the rehabilitator as a result of his negative experience; selective encouragement: competent forms of behavior are encouraged, and antisocial, aggressive ones are not. The types of incentives most desirable for the rehabilitator are used. Overcoming learned helplessness and persistent avoidance motivation, as a result of negative social experience and a long stay in the conditions of a psychoneurological boarding school, is carried out on the basis of creating a safe supportive environment, training various social skills and activating techniques, based on the principles of movement in the zone of immediate development and support of the subject position rehabilitator, in the process of gradually strengthening the working alliance based on taking into account the attitude of patients to their problems and joint cognitive conceptualization in order to check and overcome dysfunctional beliefs and develop constructive ways to solve problems. The obtained data showed the effectiveness of the developed complex rehabilitation program. After six months, during which the program was carried out, a statistically significant increase in the level of competences of all rehabilitates was recorded by experts in the selected main areas of life activity by the consensus method. Positive changes in the lives of the participants in the next three years are associated with the acquisition of limited legal capacity, employment, return to the family, transition to assisted or independent living.

Published: December 2022

We investigate the relation between the topological entropy of pseudo-Anosov maps on surfaces with punctures and the rank of the first homology of their mapping tori. On the surface \(S\) of genus \(g\) with \(n\) punctures, we show that the minimal entropy of a pseudo-Anosov map is bounded from above by \(\dfrac{(k+1)\log(k+3)}{|\chi(S)|}\) up to a constant multiple when the rank of the first homology of the mapping torus is \(k+1\) and \(k, g, n\) satisfy a certain assumption. This is a partial generalization of precedent works of Tsai and Agol-Leininger-Margalit.
A note on maximal Fourier restriction for spheres in all dimensions
Authors:   School of Mathematical Sciences, University College Cork, Western Gateway Building, Western Road, Cork, Ireland, Vitturi Marco
Published: December 2022

We prove a maximal Fourier restriction theorem for hypersurfaces in \(\mathbb{R}^{d}\) for any dimension \(d\geq 3\) in a restricted range of exponents given by the Tomas-Stein theorem (spheres being the most canonical example). The proof consists of a simple observation. When \(d=3\) the range corresponds exactly to the full Tomas-Stein one, but is otherwise a proper subset when \(d>3\). We also present an application regarding the Lebesgue points of functions in \(\mathcal{F}(L^p)\) when \(p\) is sufficiently close to 1.

RECTIFIER ANTENNA UNTUK ENERGY HARVESTING GELOMBANG ELEKTROMAGNETIK
Authors: Buwarda Sukriyah
Published: December 2022

The results of the study have obtained rectifier antennas that can convert electromagnetic waves into DC electrical energy. One of the energy harvesting methods is to use rectenna. Rectenna is an antenna that can capture electromagnetic waves that propagate freely in the air which is integrated with a rectifier that is able to convert electromagnetic waves into electrical energy. In this study, a series of power storage has been made with the aim of storing electrical energy generated by the rectifier. Two types of antennas with different frequencies are used as test equipment, namely a WiFi antenna that works at a frequency of 2.4 GHz and a TV antenna that works at a frequency of 470-806 MHz. From the results of the tests carried out, a voltage of 5.96 V was generated in the power storage circuit with a charging process duration of 54 minutes 27 seconds using a Wi-Fi antenna integrated with a rectifier and step up dc to dc converter. Meanwhile, by using a TV antenna, a voltage of 4.25 V is produced with a charging process duration of 57 minutes 19 seconds.
Antibiotic-resistant bacteria originating from the gut may modulate the mucosal immune response during sepsis and septic shock
Authors: Kalra Swinder Jeet Singh , Hari Shankar  , Nasim Mansoori  , Gupta Dablu Lal
Published: December 2022

The enrichment and diversity of gut microbiota play an important role in sepsis, but the role of gut microbiota composition and diversity in sepsis and septic shock has not yet been characterized. The impact of gut microbiota diversity on host immunological disorders and future treatments of inflammatory diseases are not yet characterized. Further, the association between the microbiota and immune development in sepsis remains unknown, and the underlying mechanisms are not well understood. The altered composition of gut microbiota during sepsis is profoundly associated with a loss of commensal bacteria and an overgrowth of potentially pathogenic bacteria; especially antibiotics resistance bacteria. The altered composition and diversity of gut microbiota especially AMR bacteria due to treatment with antibiotics may lead to the translocation of enteric bacteria across the epithelium and causes the pathogenesis of sepsis. Disruptions of gut microbiota diversity are directly associated with susceptibility to sepsis and a higher risk of adverse outcomes. Several studies have confirmed that a mutual association between gut microbiota and the host is important for the metabolism of essential nutrients for the organism, for gut development, and the maturation and development of a fully functional immune system. Therefore, depth knowledge of the gut microbiota diversity, composition, and function during various inflammatory conditions and sepsis may provide a comprehensive understanding of the mechanisms behind the pathogenesis of gut-derived infection in diseases and the design of new treatment options (e.g., probiotics or fecal microbiota transplantation).

Emerging evidence display an important role of gut microbiota and their derived metabolites in modulating the host mucosal immune response and determining the susceptibility to, as well as outcomes of sepsis.

¿Es constitucional el voto por delegación en los Parlamentos autonómicos?
Authors: García-Escudero Márquez Piedad
Published: December 2022

La sentencia comentada se plantea la constitucionalidad del voto por delegación permitido por el Reglamento del Parlamento de Cataluña, en un recurso de amparo contra la admisión de la delegación de dos diputados que voluntariamente se encontraban fuera de España y sobre los que versaba una orden judicial de busca y captura. La doctrina contenida en esta sentencia –la cual entiende aplicable a los Parlamentos autonómicos la personalidad e indelegabilidad del voto que establece para diputados y senadores el artículo 79.3 CE, aun admitiendo excepciones para salvaguardar otros valores constitucionales merecedores de protección– impone unas condiciones para que la delegación sea conforme con la Constitución: puede delegarse solo la expresión del voto y no la decisión sobre el sentido del mismo, que el diputado delegante debe haber manifestado fehacientemente con carácter previo. Estas condiciones hacen prácticamente imposible que, en los supuestos para los que puede excepcionarse la personalidad del voto y en el marco del procedimiento legislativo, sea factible la delegación. La trascendencia de la sentencia reside en la extensión de la aplicación de la doctrina que contiene a otros Parlamentos autonómicos que asimismo admiten el voto por delegación.
¿Qué es el parlamentarismo? Gobierno parlamentario, arquetipos y experiencias (una historia europea)
Authors: López Aguilar Juan F.
Published: December 2022

El parlamentarismo describe tanto la teoría como la práctica de la forma parlamentaria de Gobierno, una de las múltiples opciones de la democracia representativa. Resultado de un proceso acumulativo, el parlamentarismo ha conocido diversas expresiones políticas e institucionales. A pesar de que el tipo ideal de parlamentarismo se ha ligado tradicionalmente a la vía inglesa y británica, resulta indiscutible que esta forma de gobierno ha superado el alcance de los territorios que encuentran su origen democrático bajo la influencia de la cultura británica. De este modo, en la Europa continental se encuentran tanto un amplísimo abanico de sistemas parlamentarios con sus diversas especificidades como el espacio de referencia geopolítica de la integración supranacional europea. En este sentido, entre los casos en los que se ha materializado y consolidado este esquema institucional destaca el Parlamento Europeo, siendo el único Parlamento supraestatal del mundo. A lo largo del presente artículo se repasan no solamente los pilares de la democracia representativa y el parlamentarismo, así como diversas nociones imprescindibles para el entendimiento de estos, sino que también se analizan y exponen las peculiaridades del Parlamento Europeo, órgano particular que ha ido evolucionando y adaptándose a la naturaleza única del proceso y de la experiencia de la integración europea.

Authors: Freire Regina Maria , Cunha Maria Claudia , Mori Juliana de Souza Moraes , Palladino Ruth Ramalho Ruivo
Published: December 2022

Objetivo: investigar níveis de estresse e qualidade de vida em mães de crianças cardiopatas. Método: estudo de caráter exploratório com 23 mães de crianças cardiopatas que responderam os questionários Parental Stress Scale: Neonatal Intensive Care Unit (PSS: NICU) e Qualidade de Vida (WHOQOL-BREF). Resultados: as respostas ao WHOQOL-BREF indicaram que 17% das mães reconhecem a sua qualidade de vida como boa; 21% como precisa melhorar e 60% como regular. A escala de estresse na UTI aponta que as áreas aparência e comportamento do bebê e alteração no papel de mãe são as que causam maior estresse durante a hospitalização, considerando que entre 84% e 100% das respostas tiveram o nível máximo (nível 5) de estresse como resposta prevalente. Conclusão: Este estudo apontou alguns fatores que são, potencialmente, estressores e podem alterar a qualidade de vida das mães de crianças cardiopatas: o diagnóstico da cardiopatia infantil, as cirurgias, a hospitalização, os cuidados iniciais que se prolongam em uma doença crônica. Além disso, é provável que esta afetação esteja associada, também, a elementos constituintes de cada relação parental e familiar e que são sustentados por diferentes histórias de vida.
Determination Of Personality Types in Software Industry by Using an Expert System: A Pilot Study

Published: December 2022

The personalities of the group members working on a software development project affect the success of the work result, depending on the suitability of the team members for their roles. Therefore, it is important to determine the roles of team members in software projects according to their personality differences. This study proposes an innovative and creative expert system for determining the appropriate roles of software engineers in software projects and talent management in the software industry. The most obvious aspect of the proposed system is that it consists of questions that do not evoke the feeling of personality analysis for those who take the test. The questions are designed to be relevant to the tasks and natural behaviors of the software engineers in their projects. Software engineers often do not believe in psychometric tests and try to manipulate them. Furthermore, the number of questions in these tests is quite large, so they can get bored. The proposed test was compared with the results of the Jung-Based Software Talent Management (JBSTM) and the Keirsey Temperament Sorter test. These two tests were applied to 20 software industry employees in a single session in a random order. A comparison questionnaire was completed after the tests. A moderate correlation between JBSTM and the Keirsey test appeared in E / I, T / F and J / P. The JBTSM and Keirsey test results were also compared in terms of test completion times. Using the results of the comparison questionnaire, the JBTSM and Keirsey test were also compared in terms of easiness, suitability, comfort and usefulness, and it was found that the JBTSM received higher scores compared to the Keirsey test in all four respects.

Uterine tubes (UTs) are essential during physiological reproduction. The most intriguing part of its wall is the mucosa. Apart from the epithelial cells vital for its normal function, the connective tissue lamina propria contains wide spaces whose function, morphology and structure are yet to be elucidated. The present study used bioptic samples from 25 premenopausal (mean age 48.3 years, σ=3.56) and 25 postmenopausal women (mean age 57.8 years, σ=7.79). In both study groups, samples were obtained from two anatomically distinct parts of the UT – ampulla and infundibulum with fimbriae. The specimens were processed for scanning electron microscopy (SEM) and immunohistochemical detection of podoplanin (clone D2-40) and VEGFR-3 – two markers of lymphatic endothelial cells. The results showed that specimens from premenopausal and postmenopausal women contain wide lymphatic spaces, also known as lymphatic lacunae. The most probable function of the lacunae in the fimbriae is oocyte pick-up upon ovulation thanks to their ability to get engorged with lymph, thus serving as an erectile-like tissue. The ampullary lacunae are probably responsible for tubal fluid maintenance and recirculation. These results indicate that they are vital for normal reproduction because tubal fluid dynamics are as important as fluid composition. Further research on this topic is highly warranted because more detailed insights into UT function have a great potential to refine the methods of reproductive medicine, e.g. in vitro fertilization (IVF), which are still far from optimal regarding fertility outcomes.
A unique anatomical variation of the vascular supply of the ovary, uterine tube, and uterus from the greater omentum – an anatomical case study

Published: December 2022

It is well known that the blood supply of the greater omentum and female internal genital organs are not physiologically connected. There is also no mention of such anatomical variation in anatomical, radiological, or surgical textbooks. Here we present a very rare case report of atypical double arterial anastomosis (the first and second variant artery) between the right limb of the omental arcade of Barkow, uterus, and right ovary, which was found during a routine student anatomical dissection course. It is very challenging to find a proper explanation for the presence of the described anatomical variation; however, we hypothesized that it is based on their common embryonic origin - the mesentery. The first and second variant arteries could be remnants of transient anastomoses or collateral circulation, which were present during embryonic development and persisted until adulthood. Moreover, during our literature review, we noticed that the general description of omental blood supply and its possible variations is relatively poor; therefore, we emphasize the need for more precise knowledge regarding these anatomical parts, which could help surgeons who are performing abdominal or pelvic surgeries in preventing avoidable bleeding.
The struggle of world powers and the future of democracy
Authors: Antonovich Ivan I.
Published: December 2022

The problem of the future of democracy is of serious concern for the academic community of the Western countries, where democracy has been a stable form of political power. Today it is possible to discern two schools of the study of democracy – European, which is represented mostly by the researches from Germany and France, and the American one. European scholars construct a unified system of the global democratic governance, when democratic countries develop an autonomous system from bottom to top, which produces a unitary, universal model on the basis of the egalitarian cooperation. American researchers in fact envision a similar model of the global democratic governance while suggesting that it is constructed on the basis of the American model of democracy.

Published: December 2022

The object of the research is Soviet animation of the period of 1950–1990. The author examines the stages of animation development, as well as the transformation of the main artistic methods and images used by Soviet animators. The relationship between the features of the development of animation and cultural and historical processes in the USSR is revealed. The influence of the ideological foundations broadcast from above on the industry is shown. In the course of the study, the main tasks of Soviet animation were identified, which can be traced in the cartoons of the period under review. Content analysis is used as a research method. The main films of each decade of the Soviet era were selected and analysed, and a secondary analysis of research on animation was carried out. The idea of the article is, firstly, to show how ideology changed in the Soviet era, and secondly, how these ideological attitudes were broadcast through cartoons. In the article, Soviet animation is analysed as a means of ideological influence of the authorities on society and the formation of a Soviet citizen. The author’s contribution consists in an attempt to systematise a number of animated films in accordance with their intended ideological content.
