Over Exposure – Under Observation. Eine Berner Momentaufnahme zeitgenössischer Partizipation
Authors: Wehrle Annika
Published: March 2021

Stimme ab, nimm teil, teile Dich mit, sei dabei! Der Ruf nach Partizipation ist heute allgegenwärtig. Sind damit aber auch Räume wirkmächtiger Beteiligung und Entscheidung verbunden, oder handelt es sich um scheindemokratische Inszenierungsstrategien? Wer erhält nach welchen Spielregeln Zugang zu den (politischen) Bühnen der Gegenwart? 

Die heutige Landschaft performativer Künste hat sich zu einer Spielwiese ausdifferenzierter Partizipationsformen entwickelt. War das Theater im Laufe seiner langen Geschichte immer schon ein Ort der Teilhabe und Interaktion, wandelten sich mit den politischen Kontexten, den Machtdispositiven und medialen Verschiebungen stets die Rollen, Funktionen und Kommunikationsanordnungen des Publikums. So stehen heutige Künstler_innen vor der Aufgabe, theatrale Partizipation vor der Folie digitalisierter, globalisierter und mobilisierter Lebenswelten neu zu denken und nach Räumen und Beteiligungsformen zu suchen, mittels derer die performativen Künste ihr politisches, diskursives Potenzial entfalten können. 

Entlang des assoziationsreichen Bedeutungsspektrums des Begriffs ›overexposure‹, den das internationale Theaterfestival AUAWIRLEBEN in Bern 2017 zum Motto gewählt hat, fragt der Beitrag nach den Wechselwirkungen performativer und gesellschaftlicher Partizipation im 21. Jahrhundert und legt neuralgische Punkte, Widersprüchlichkeiten und Spannungsfelder offen, die eine Reperspektivierung des zeitgenössischen Publikumsbegriffs mit sich bringt.
Ethical values in jujutsu of Japanese origin
Authors: Cynarski Wojciech J. , Yu Jong-Hoon
Published: March 2021

Background. The broad humanistic and socio-cultural theoretical perspectives applied to this research effort provides a foundation for the Humanistic Theory of Martial Arts and the anthropological Focus on martial arts used in this paper. Hence, conceptual language has been adopted for this investigation. The aim is to assess and identify the ethical values and pro-social perspectives accentuated by high ranking masters in the martial art of jujutsu. Specifically, this paper seeks to answer the question of which values are most often prioritized or stressed? Method. The discussion involves the analysis of a broad survey of scientific and expert literature. Quoted and compared are the opinions and perspectives of 11 Grand Masters of jujutsu, holders of the highest titles and master's degrees (i.e, 9-10 dan), are analyzed and presented as evidence. Results. Classical schools and their representatives uniformly accentuate the value of tradition. On the other hand, there is a trend toward modernization both in the content of teaching and in technical ideas. This modernization began with Jigoro Kano, whose followers are today seen as reformers. All present Grand Masters pay attention to the ethical values and educational aspects of martial arts, particularly with regard to jujutsu. Conclusions. Ethics in jujutsu extends, as a kind of continuum between the traditionalist Butoku (i.e, knightly virtues resulting from Bushido) and the axiology of Christian Europe. A general consensus exists as to its educational and pro-social values. Aspects may also include self-control, self-discipline, perseverance, and responsibility, which are shaped by long-term educational processes.

Published: March 2021

The aim of the study is to determine the effects of a multidisciplinary lifestyle intervention (including a short period of physical exercise) on some health-related variables, particularly on blood pressure, in an overweight/obese adult group. The main outcome was blood pressure lowering. The study involved 378 subjects affected by obesity or type 2 diabetes. The intervention included exercise, nutrition and psychological aspects. Before and after the intervention, several anthropometrics, cardiovascular risk related measures (height, body weight, body mass index, waist circumference, body composition and WHTR index) and physical exercise measures (aerobic capacity, flexibility and dynamic muscle strength) were evaluated through fitness tests. We observed a significant reduction in: blood pressure values, body weight, BMI, waist circumference, WHTR, fat mass and an improvement of fat free mass and physical exercise measures. The C.U.R.I.A.Mo. multidisciplinary approach is effective for reducing blood pressure, after relatively few exercise sessions (three weeks), particularly in patients with hypertension. The intervention can ameliorate the health status and physical performance in the short term, in normotensive and hypertensive adult subjects with overweight/obesity.

Authors: Zureigat Ayed , Fattah Osama Abdel
Published: March 2021

Background: It is well known that advancing age is accompanied by many negative feelings due to the feeling of loneliness and psychological emptiness, which leads to the individual feeling that society does not need him due to his weak physical abilities and thus this, will negatively affect healthy aging. Objective: The study aimed to investigate the effect of the leisure activities on the psychological stress among the elderly during Coronavirus (COVID-19) Outbreak. Design: To achieve this, we used the quasi-experimental approach on a sample consisting of 54, with the average age of (65.4±2.3) years. Divided into two groups 27 as a control group and 27 as the experimental group and this sample was purposively selected. Because of the home quarantine and to reduce face-to-face interaction, we used a questionnaire to measure the psychological stress level by using the Google form. The study tool consisted of 7 paragraphs associated with depression and 6 paragraphs associated with anxiety, finally 6 paragraphs associated with aggression. Before applying the experiment, the psychological stress was measured among the study sample, and then the leisure activities program was sent to the experimental group by the WhatsApp application. The researchers used means, standard deviations, paired and independent sample t-test by using SPSS version 24 with a confidence level of 95% (p<0.05). Results: The results of the study have shown that the level of the psychological stress among both groups came with a high average in the pre-measurement, as well as the anxiety domain that were the most affected in a positive way through leisure activities practicing. Additionally, there were statistically significant differences between the pre and post measurement among experiment group and favor of the post measurement. Conclusion: the leisure activities practicing among the elderly have contributed positively to reducing the level of psychological stress represented by depression, anxiety.

Published: March 2021

Saif et al. (J. Math. Comput. Sci. 21 (2020) 127-135) considered modified Laplace transform and developed some of their certain properties and relations. Motivated by this work, in this paper, we define modified Sumudu transform and investigate many properties and relations including modified Sumudu transforms of the power function, sine, cosine, hyperbolic sine, hyperbolic cosine, exponential function, and function derivatives. Moreover, we attain two shifting properties and a scale preserving theorem for the modified Sumudu transform. We give modified inverse Sumudu transform and investigate some relations and examples. Furthermore, we show that the modified Sumudu transform is the theoretical dual transform to the modified Laplace transform.
Instructional Practices Affecting Learner Engagement in Blended Learning Environments
Authors: ÖNCÜ Semiral , BICHELMEYER Barbara
Published: March 2021

Learners have to engage in academically purposeful instructional endeavors to be successful in school. Latest research indicates that the learners of today are not as interested in educational deeds as they need to be. Educational stakeholders should look for means to address this tendency to have a positive influence on educational results. This study explores the instructional practices that play a role in behavioral engagement (also known as involvement) of learners in schoolwork in the Cisco Certified Network Associate (CCNA) program – an information technology certificate program. Behavioral engagement in this context refers to learners’ active learning and collaboration with peers. A two-level hierarchical linear modeling was established to predict behavioral engagement from instructional practices while controlling for certain learner level (expectancy and value motivation, gender, and age) and teacher level (teaching and networking experience) variables. Learners who attended the CCNA program in the United States, totaling 773 high school and community college students, were matched specifically with 149 teachers who taught them. Student and instructor surveys were conducted online to gather data. The results show that the level of learner involvement in the program was poor, equivalent to the national student engagement survey of the period. However, if their teachers used collaborative and learner-centered practices, learners were more involved in schoolwork behaviorally. Learners were also very involved in the program if they placed a high value on the program. Female learners were not as active as male learners. In addition to the two instructional practices implied in this study, another major takeaway is that learners should be advised as early as possible about the detrimental impact of poor motivation in the program.

Authors: CANLI Suzan , KARADAĞ Nülifer
Published: March 2021

The present study aimed to investigate the motivation to teach of the teachers and to determine the factors that affect motivation to teach. Convergent parallel mixed design was used in the study. The study sample included 157 teachers who were selected with the convenience sampling method. A data collection instrument that consisted of three sections was used to collect the study data. In the first part of the instrument, questions about personal variables and school stakeholders (administrator, colleague, student and parents) are included. In the second part, "Teaching Motivation Scale" developed by Kauffman, Yılmaz-Soylu and Duke (2011) and adapted into Turkish by Ayık, Ataş-Akdemir and Seçer (2015) takes place. In the third part, there are two open-ended questions created by the researcher. Descriptive statistics, independent samples t-test, Mann-Whitney U test, one-way analysis of variance, and content analysis were used to analyze the study data. In the study, it was observed that quantitative and qualitative findings were generally consistent. It was determined that attitudes and behavior of school administrators, students, colleagues, and parents towards the teachers and attitudes and behavior of the students towards the course were the factors that affected the motivation to teach of the teachers. It was determined that the marital status and professional seniority of the teachers did not affect the motivation to teach of the teachers. While quantitative findings demonstrated that gender affected extrinsic motivation to teach, there was no qualitative evidence that gender affected motivation to teach. In the study, various recommendations such as supporting teachers, appreciation of their work, and showing respect were presented in the study to improve the motivation to teach of the teachers.

Authors: TAVŞANLI Ömer Faruk , KARA Ülkü Eda
Published: March 2021

In studies conducted to improve primary school students' writing skills, it has been determined that they make errors in the use of the punctuation marks and do not use spelling rules correctly. The purpose of this study was to reveal the effect of a qualified and planned peer and self-assessment-based editorial study [PSABES] on the success of fourth-grade elementary school students in following spelling rules and using punctuation correctly. In this study, an explanatory mixed design was used, and the research was carried out with 60 fourth-grade students attending a public school in Istanbul during the 2019-2020 academic year. According to the results of the research, it was determined that PSABES was effective in students' performance in adhering to spelling rules and using punctuation correctly. This was due to PSABES’ contribution to creating a positive attitude toward writing, increasing motivation, learning desire and communication skills, and allowing students to gain a culture of criticism, feel more valuable, recognize their mistakes, take responsibility and write more carefully. This research clearly demonstrates the effects of peer and self-assessment on the correct use of spelling rules, and punctuation marks. In subsequent research, the effects of self and peer assessment on students' overall writing success can be examined, and it can also be investigated how this process plays a role in shaping the writer identity of students.

Poland, as a member state of the European Union, made various adjustments to the education system during the coronavirus pandemic. In this process, as in many countries, distance learning came to the fore. In Poland, the positive and negative aspects of the distance learning process, the relationships between students, teachers and teaching activities have become the subject of various studies. In the first stage, these studies were carried out through official institutions in order to obtain feedback about the process. The purpose of this research is to reveal the problems, changes and application samples in the Polish education system, and to examine the impact of remote learning on gifted students. This paper was designed with a case study, which is one of the qualitative research methods. The data obtained was analyzed using content analysis. The impacts of the Covid-19 pandemic on the education system are addressed by thematic groups. It has been observed that the changes implemented as a response to the pandemic have had various effects on teachers, students, parents, technological opportunities, motivation and teaching activities. It has been determined that the pandemic has seriously affected the identification and education of gifted students. Additionally, it was observed that students gained the ability to recognize and work with a new learning-teaching process through distance learning.

Published: March 2021

The use of a storage tank to regulate the loads of the mini-CHP plant improves the technical and economic indicators of its operation. However, the results of studies of the use of a storage tank in heating systems, in contrast to hot water supply systems, are poorly represented. The purpose of the study is to determine the conditions and indicators under which the use of a storage tank to regulate the heating load of a mini-CHPP is economically viable. The study of the heat grid is based on solving the standard heat balance and heat transfer equations. Modeling of heat transfer in the heat recovery circuit of a cogeneration unit is carried out by approximating the passport specification of the equipment in the range of operating loads from 50 to 100 %. Modeling the standing time of the outside air temperatures is carried out in accordance with the method of B. Shifrinson and V.Ya. Khasilev. The conditions of the numerical study are quite typical for the heating network of Donetsk. For the first time, to satisfy the conditions of a numerical study, the dependence of the available and used thermal capacity of the storage tank on the outside air temperature has been established for different values of the design volume of the tank. The quantitative characteristics of the influence of the design volume of the storage tank on electricity generation during peak, half-peak and minimum power system loads are investigated. The reliability of the results obtained is determined by the correct use of proven methods for calculating the operation parameters of water heating system and heat devices. The study shows that the use of a storage tank to regulate the heating load of a mini-CHPP is technically and economically feasible. With the design volume of the storage tank in the range of 65–126 m3 per 1 MW of the connected heating load, the simple payback period of the mini-CHPP varies insignificantly and can be considered acceptable. The presence of a storage tank allows realizing the maneuverable capabilities of cogeneration units, while maintaining a high share of energy generation in combined mode. The district heating coefficient, equal to one, allows achieving high efficiency of fuel utilization for generation of both electrical and thermal energy. The research results can be used in municipal heat supply systems when introducing gas piston cogeneration units.
Ways of constructing of measuring and starting elements of microprocessor devices of fast acting automatic transfer switch
Authors: Derkachev S.V.
Published: March 2021

Microprocessor devices of fast-acting automatic transfer switch (FATS) are widely spread in modern net-works to increase the reliability of power supply of industrial plants in case of short-term violations of normal power supply mode. Presence of motor load in such networks requires minimizing the power interruption time to provide more favorable conditions for self-starting of electric motors. However, currently existing operation algorithms of measuring elements of FATS devices are based on the decomposition of the measured signal by using a Fourier integral, and require observation interval equals to the period of the industrial frequency. The known directional elements that are used in microprocessor-based FATS devices do not ensure reliable operation of the device with asymmetric and nearby fault. Therefore, the purpose of the work is to increase the speed of operation of the algorithms of the measuring elements of microprocessor devices of FATS, as well as to increase the reliability of the starting directional element in case of nearby fault and deep voltage drops. To achieve this goal the author uses the method of computer simulation. The method of a full-scale experiment on a laboratory bench to verify the obtained theoretical results is used. The author improves the algorithm to determine the orthogonal components of the measured current and voltage signals by integral averaging of instantaneous discrete values of the measured signals and their derivatives over the observation interval with a duration of less than a half-period of the industrial frequency. The algorithm of the operation of the starting directional element in case of deep voltage drops caused by nearby fault in both the external and internal power supply network has been improved by using the main power supply voltage from the added memory element of the pre-fault measurement cycle as a reference voltage to determine the power direction. The obtained results show that the proposed algorithm for the operation of the measuring elements will make it possible to obtain the value of the phase and amplitude of the measured signal in a time equals to 0,005 s. and use of an improved starting directional element makes it possible to increase its reliability in case of deep voltage drops and asymmetric short circuits. The proposed algorithms of operation of the measuring elements and the starting directional element can be used in FATS devices.

AimTo analyze cases of idiopathic recurrent pericarditis (IRP) in the structure of pericardial diseases of various origins from patient visits to the Multidisciplinary Federal Center.Material and methodsA retrospective analysis of case records was performed for patients admitted to the V.A. Almazov National Medical Research Center from January 1, 2015 through January 1, 2020 for pericardial effusion of different etiologies.ResultsFor the study period, 4 981 new cases of pericardial damage of different etiologies were found. Among these cases, postpericardiotomy syndrome accounted for 4 360 cases and pericarditis for 621 cases. IRP was detected in 34 cases, which amounted to 5.4 %. Based on the study data, the estimated IRP prevalence in the Russian Federation can be 1.1 cases per 100 thousand population.ConclusionIRP should be regarded as a new autoinflammatory disease, the prevalence of which borders on that of adult Still disease and should be addressed within the concept of orphan diseases. Current knowledge of the pathogenesis and data from recent studies demonstrated a great importance of interleukin-1 blockade as a leading mechanism for achieving remission. This has justified conduction of a randomized clinical study at the Center.

AIM: To evaluate the role of a single intravitreal injection of tissue plasminogen activator alone (TPA) for treatment of vitreomacular traction and the effect of combined intravitreal TPA and bevacizumab on retinal vascular diseases.
METHODS: In this prospective, interventional case series a total of 24 eyes from 24 patients were studied. There were 5 eyes with symptomatic vitreomacular traction syndrome (VMT) and 19 eyes with retinal vascular diseases including diabetic macular edema (DME), diabetic vitreous hemorrhage (VH), central retinal vein occlusion (CRVO) and neovascular age related macular degeneration (AMD). Measurement of visual acuity, B-scan and OCT were performed at the baseline and 1mo after injections. Three eyes with VMT received a single intravitreal injection of 50 μg and two eyes received 100 μg TPA. Totally 19 eyes with retinal vascular diseases received combined intravitreal TPA (50 μg) and Bevacizumab (1.25 mg).
RESULTS: The mean ages for retinal vascular diseases and VMT patients were 56.8y and 60.4y, respectively. Ten patients (41.7%) were male and 14 patients (58.3%) were female. 22 eyes (91.7%) were phakic and 2 eyes (8.3%) were pseudophakic. The incidence of posterior vitreous detachment (PVD) was 0% (0 of 5) and 57.8% (11 of 19) for VMT and retinal vascular diseases, respectively (P=0.04). Improvement of best corrected visual acuity (BCVA) and decrement of central macular thickness (CMT) were significantly greater in PVD positive eyes compared with PVD negative eyes.
CONCLUSION: Intravitreal injection of TPA was not successful to induce complete PVD in VMT patients. Combined intravitreal injection of TPA and Bevacizumab can induce PVD and improve BCVA and decrease central macular thickness in eyes with retinal vascular diseases.

AIM: To evaluate advantages of chandelier illumination system during scleral buckling (SB) procedures for rhegmatogenous retinal detachment (RRD) surgery.
METHODS: In this comparative, retrospective study, 72 eyes of 72 patients undergoing SB for RRD at Minerva Hospital (Santa Maria Capua Vetere, Italy), divided in 2 groups of 36 eyes each were collected. In one group (A) eyes underwent SB with chandelier, in the other one (B) eyes underwent SB without using chandelier illumination system. Every eye of both groups was checked before surgery and at 1, 3, 7, 14, 30, 90 and 180d follow up. Parameters such as additional procedures, best spectacles visual acuity (BSVA; measured with Snellen Lines as decimal fraction), surgical time and retinal breaks recurrences had been analyzed before and after surgery and statistical comparison have been run between two groups.
RESULTS: A significant (P<0.01) improvement in BSVA was observed at 6mo follow up in both groups; comparing groups A and B, no significant clinical differences was found in recurrences rate whereas mean surgical time in group A was statistically lower than the group B ones.
CONCLUSION: According to results observed, even if they need to be confirmed in further studies with larger population, chandelier illumination system could be considered a valuable tool for SB surgery in eyes affected by RRD.

AIM: To explore the safe movement angle of a 23-gauge (G) cannula in double-channel silicone oil (SO) removal surgery.
METHODS: From March 2017 to September 2017, 15 patients with SO filled eyes were enrolled in this retrospective analysis. Based on ultrasound biomicroscopy (UBM), the distance from the front surface of the sclera at the 2 o’clock and the 10 o’clock positions to the SO bubble at 4 mm behind the corneal limbus was measured and defined as “A”. The length of the 23G cannula (4 mm) was defined as “C”. The width of the scleral inner wall at the maximum operating angle of the scleral trocar was defined as “B”. The safe movement angle of the 23G cannula was determined according to the trigonometric function table. Using the self-made SO removal device connected to the 23G puncture cannula, the SO was successfully removed from all patients.
RESULTS: The average SO removal time for all patients was 4.78±0.13min. The trigonometric function was used to work out the distance from the scleral front surface to the SO bubble, which was 0.82-2.81 mm (1.62±0.41 mm) at the 2 o’clock position, and 0.98-2.19 mm (1.71±0.34 mm) at the 10 o’clock position. Finally, the verification analysis using geometric model calculation showed that the optimal movement angle of the cannula was 52°.
CONCLUSION: Combining the trigonometric function and UBM measurement to calculate the safe movement angle of a 23G cannula can effectively guide the moving range of the trocar during SO removal. A movement angle of the cannula larger than 50° may avoid the occurrence of a retinal tear.

Published: March 2021

Прогнозирование является важным инструментом в деятельности ученых и исследователей социально- экономической сферы. Его использование позволяет предполагать варианты будущего и находить на них своевременные адекватные и эффективные ответы. Прогнозирование показателей регионального развития в свою очередь позволяет формировать необходимую национальную политику в отношении субъектов хозяйствования, которые нуждаются в государственной поддержке, либо перераспределении ресурсов из элементов экономической системы, имеющих их в свою очередь в избытке. Целью данной статьи является разработка и апробация соответствующего инструментария, моделирующего прогнозные сценарии динамики показателей развития, являющихся социально- экономическими характеристиками региона. В качестве базиса построения прогнозов взяты трендовые модели, выраженные элементарными математическими функциями. Помимо этого, представлен алгоритм моделирования сценариев и коридора значений прогнозируемой величины. Апробация разработанного инструмента проделана на статистических показателях Российской Федерации и Пермского края, характеризующих развитие и уровень влияния IT-технологий на исследуемой территории.
Роль рынка государственных и муниципальных закупок в региональной экономике
Authors: Аничин Владислав Леонидович , Ващейкин Игорь Викторович
Published: March 2021

Закупочная деятельность для государственных и муниципальных нужд практикуется во всех странах. В ряде публикаций указывается, что в развитых странах общая сумма заключаемых контрактов составляет значительную долю от ВВП. Такое сопоставление следует признать некорректным, поскольку сопоставляемые величины различаются по своей структуре. Более обосновано использовать в качестве базы сравнения совокупный оборот организаций. В исследовании определены параметры статистической связи между оборотом организаций и доходной частью региональных бюджетов ЦФО, между среднедушевыми бюджетными доходами и суммой размещенных контрактов в расчете на одного жителя. Оценена динамика соотношения общей суммы размещенных контрактов и оборота организаций. С учетом того, что размещение контрактов по итогам конкурсных процедур среди организаций нерезидентов региона влечет недополучение бюджетных доходов в размере 3,3 руб. на 100 руб. суммы контракта, имеются основания для установления дифференцированных цен в зависимости от того, является ли подрядчик резидентом или нет.

Дискурсивный сетевой анализ: дискурсивно-динамический аспект исследования публичной политики
Authors: Корюшкин Александр Иванович
Published: March 2021

Объектом анализа статьи является концепт дискурсивного сетевого анализа, предложенный британским политологом Филипом Лейфелдом, и, прежде всего, его сущностные характеристики, позволяющие оценить объяснительный потенциал такого концепта, представляющего собой комбинацию качественного контент-анализа и количественного сетевого анализа. Здесь интерпретируется принципиальная важность определения в этом концепте публичных политических дебатов в качестве динамичных дискурсивных сетей, дискутирующих проблемы конкретных политических курсов в их развитии, детальной творческой разработки в нем центрального понятия «политический дискурс», подчеркивающей его динамическую природу, также значимость объединения в его методологии актор-ориентированных и контент- ориентированных подходов к изучению политических дискурсов конкретных политических курсов, что позволяет концептуализировать и замерять ко-эволюцию акторов и их контентов в процессе динамичных изменений выработки, реформирования и смены политических курсов, обеспечивая возможность их долгосрочного мониторинга.
La primacía de los derechos sociales relacionados con un nivel de vida adecuado: una reivindicación (in)esperada de la pandemia

Published: March 2021

Este trabajo se propone mostrar cómo la pandemia originada por el COVID-19 ha provocado el replanteamiento de la mirada liberal de los derechos humanos que venía invalidando ya todo discurso acerca de su interdependencia e indivisibilidad. Al legitimar la limitación de ciertas libertades, a la vez que se ponderaba la urgencia de asegurar un nivel de vida adecuado para todos, la particular situación de emergencia mostró la postergación de la cual los derechos sociales vienen siendo objeto en el modelo jurídico vigente desde la Modernidad. La primacía y fundamentalidad de los derechos relacionados con un nivel de vida adecuado se ha postergado por un derecho que los dio por presupuestos. La situación de crisis presenta una nueva oportunidad para su reivindicación, en cuanto condición de realización de cualquier otro derecho, de cualquier convivencia social.

The article conducts a legal analysis of the case-law of the European Court of Human Rights on the protection of the right to non-discrimination, which is a fundamental and general principle concerning human rights protection. During the period of functioning of the ECtHR, the Court has processed a huge amount of cases concerning violation of the right to equality and the inextricably linked principle of non-discrimination under Art. 14 and Art. 1 of Protocol № 12 of the ECHR. The evolution of the interpretation of the ECtHR shows the transformation of approaches to the interpretation of the right to non-discrimination. The court gradually began to expand the range of possible violations, from outright prohibition to the detection and the statement of indirect discrimination, and its decisions contributed to the normative formulations of the principle of non-discrimination in national systems and its gradual transformation from a purely declarative to a coherent effective mechanism of protection of discrimination victims and a mechanism of the approval of democracy, human dignity. The rule of law forms the central principle of interpretation of the Convention. A consensual investigation allows the ECHR to tie its decisions to the pace of change in national law, recognizing the political sovereignty of the respondent States and, at the same time, legitimizing its own decisions against them, adhering to the principles of a democratic state governed by the rule of law. The purpose of this article is to analyze peculiarities of the ECtHR's interpretive practice in cases concerning the right to non-discrimination.
Doctrinal Differences in the Definition of the Principles of Public International Law

The ambiguity of scholars' vision of the content of the principles of international law and their corresponding definition in doctrinal discussions can be reduced to two main directions. First, it is a problem of coverage of the concepts of principles of international law of generally accepted principles of law, and, secondly, the problem of limiting the category of principles of public international law to only ten basic principles of international law. These discussions confirm the relevance and urgency of its solution. The general principles of international law, as the inheritance of all mankind, are the result of the development of all legal systems of the world in its legal unity. These principles represent the unity of the general principles of international law, which are inherent only in the international legal system; general principles of law inherent in both national and international legal systems, as the ideological foundations of law; and common principles of national legal systems, which with certain comments can be applied to international legal relations. If we take as a basis Art. 38 of the Statute of the UN ICJ as a conditional list of sources of international law, where generally accepted principles of international law are not provided as such, the interpretation of this article can be imagined as conclusions that the principles of international law as special to general principles of law are norms of international law its reflection in any of the sources of international law, including those, which are unforeseen articles 38 of the Statute of the UN ICJ. The main difference between the principles of international law and general principles of law is that they contain specific rights and obligations for subjects of international law and are directly a regulator of international relations. Such unity can be deduced from the normative interpretation of Art. 38 of the UN Statute, in particular: the sources of enshrining the general principles of international law are customs and international treaties in accordance with paragraph a and paragraph b of Art. 38; the source of the general principles of law is paragraph c of Art. 38 of the Statute of the UN ICJ (general principles of law recognized by civilized nations); the source of identification or the legal basis for the application of the common principles of national law is paragraph d - ex aequo et bono, their application by an international court on the basis of the principle of justice.

The current stage of civilization development is characterized by fundamental transformations in almost all spheres of human existence, mainly economic, social, political, and cultural. All of them take place under a huge influence of the global information society. With the undoubted success of modern technology, which has achieved the most impressive results in the field of information technology, the philosophical community is growing a genuine and justified anxiety about the moral and ethical threats to human existence, which tend to be a result of scientific and technological development. As a result, false communication, alienation and loneliness define the moral flaws of the modern information society. In this situation, the revival of basic ethical principles and ethical bedrocks of human existence and culture becomes especially acute and necessary.

The article examines the phenomenon of mediation as a value of a developed civil society from the ideological and methodological positions of the anthroposociocultural approach. The general historical conditions of the emergence of mediation and its anthroposociocultural code, paradigmatic types of mediation and the most important properties of each of them are analyzed. The article reveals the value nature of mediation as a Copernican revolution in ideology and methods of constructive resolution of conflicts between individuals and their communities. The conclusions are substantiated that: mediation belongs to the genus of anthroposociocultural values as their qualitatively distinguished type; mediation is functionally related to fundamental universal human values - human rights, the rule of law and pluralistic democracy - as a tool for their protection by human beings themselves in the form of a joint solution of interpersonal conflicts by their own carriers with the help of professional mediators; modern science distinguishes at least two paradigmatically different types of mediation - traditional mediation and narrative mediation; mediation of the first type as a value is applied mainly to the solution of interpersonal conflicts, and mediation of the second type is mainly applied to the solution of conflicts between human communities in polyidentical societies.

We live in a postmodern society, characterized by an individual morality, ethical minimalism, etc., or we could call it liquid modernity, twilight of debt or late modernity, as Jürgen Habermas stated. Considering the conditions of such a society, where even education is achieved through ICT technologies, we consider it appropriate to make a brief review of subjective civil rights. Hence, we considered it opportune to discuss non-patrimonial rights, namely those concerning the dignity and physical and moral integrity of the person.
