Die Autonomie des Sports, die verfassungsrechtlich verbrieft ist, wird durch das Gemeinschaftsrecht der EU nicht konsequent respektiert. So wird beklagt, dass die notwendige Kooperation der Verbände im Sport nicht hinreichend berücksichtigt wird. Hier setzen die Referenten des 9. Internationalen Hamburger Symposiums „Sport und Ökonomie“ an, wenn sie rechtliche und ökonomische Fragen um Sportgroßveranstaltungen aufgreifen und Vorschläge zur Stellung des Sports im europäischen Rahmen diskutieren. Aufgezeigt wird , dass der sogenannte Sport ökonomisch geprägt wird, was noch keine angemessene Entsprechung auf europäischer Ebene gefunden hat. Das wird zum Beispiel bei Sportwetten und dem Glücksspielmonopol deutlich.
Der Band wird die durch das EU-Weißbuch Sport und die Entschließung des Bundestages zum Sport in Europa entstandene Debatte weiter beleben.

Mit der vorliegenden Publikation würdigen das Landesarchiv Schleswig-Holstein und die dänischen Staatsarchive den 75. Jahrestag der Unterzeichnung des deutsch-dänischen Archivabkommens. Wie es in der deutsch-dänischen Archivzusammenarbeit bereits Tradition ist, geschieht dies auf Deutsch und auf Dänisch. Alle Texte der Publikation liegen deshalb in beiden Sprachen vor.
Der damalige Archivar Hans Kargaard Thomsen, Kopenhagen, hat in den 1990er Jahren einen ausführlichen Bericht unter der Überschrift „Arkivoverenskomsten med Tyskland 1933 og dens forhistorie“ („Das Archivabkommen mit Deutschland von 1933 und seine Vorgeschichte“) verfasst. Er bildet das Kernstück der Veröffentlichung. Darauf folgen Handreichungen zur Benutzung der Archivalien, die aufgrund des Abkommens zwischen Deutschland und Dänemark 1936 ausgetauscht wurden. Die Archivare Malte Bischoff, Landesarchiv Schleswig-Holstein, und Hans Schultz Hansen, Landsarkivet for Sønderjylland, sind die Autoren dieser Texte.

Aim. To study the structural and functional left heart parameters in patients with severe aortic stenosis (AS) and preserved ejection fraction (EF) in order to determine the risk of atrial fibrillation (AF).Material and methods. The study included 84 patients (men, 37; mean age, 68±8 years) with severe AS and EF >55%. All patients had sinus rhythm and were asymptomatic. Echocardiography was performed to assess longitudinal strain of the left ventricle (LVLS), right ventricle, left atrium (LALS) and the left atrial stiffness (LAS) using the speckle tracking method. Left ventricular mass index (LVMI) and maximum left atrium volume index (LAVI) were also determined. Patients were followed up for 1 year.Results. AF was reported in 27 (32%) patients, of which 9 (33%) had asymptomatic AF episodes detected by 48-hour electrocardiography. Eighteen (67%) patients with AF felt palpitations. Patients with and without episodes of atrial fibrillation had non-significant differences in LVMI, LAVI, and LVLS. Patients with atrial fibrillation had a lower LALS and a higher LAS compared with patients without atrial fibrillation. Regression analysis revealed that LALS and LAS were independent predictors of AF.Conclusion. AF develops in about one third of asymptomatic patients with severe AS and normal EF. The development of AF predisposes to the onset of AS symptoms in most patients. LALS and LAS were predictors of AF in these patients. Identification of patients at risk of AF will allow for earlier aortic valve replacement.

Aim. To develop a protocol for diagnosing exercise-induced arrhythmias and conduction disturbances in children aged 3-6 years without structural heart disease.Material and methods. The study included 20 patients (11 boys) aged 58,7±2,12 months with ventricular arrhythmias (VA) and/or atrioventricular (AV) block according to single electrocardiographic (ECG) records and/or 24-hour ECG monitoring. All patients underwent a thorough clinical and paraclinical examination, including exercise stress testing using original and Bruce protocols. The termination criteria were the first of following events: achievement of the heart rate set by the study aim; the appearance and/or aggravation of potentially dangerous arrhythmias and conduction disorders (single premature ventricular contraction (PVCs) with increasing frequency, and/or early PVCs, and/or paired PVCs, and/ or ventricular tachycardia (VT), and/or AV block); registration of allorhythmia (bigeminy) within 10 seconds.Results. The termination criteria using the original protocol were achieved in all patients (n=20, 100%) compared to the standard Bruce protocol (n=5, 25,0%), p<0,001. The number of steps passed was significantly higher using original protocol (5,0 [5,00-6,00]) than when using the standard protocol Bruce 2,0 [2,03,0], p<0,05. Exercise tolerance was significantly higher when using the original protocol than the standard Bruce protocol (p<0,05). The probability of reaching the termination criteria using the original protocol were 116 times greater than using the standard Bruce protocol (odds ratio, 116, 95% confidence interval: 5,932250, p=0,0017). VAs were registered in 20,0% (n=4) of patients using the original protocol, while AV blocks — in 20,0% (n=4). Among the five patients who achieved the termination criteria using the standard Bruce protocol, VAs were recorded in 10,0% (n=2) of patients, while AV blocks — in 5,00% (n=1).Conclusion. The use of exercise test with an original protocol makes it possible to achieve the termination criteria, increases its information content and diagnostic significance. It makes it possible to determine the nature of VAs and AV conduction dosorders.

Published: August 2022

Aim. To study the relationship between a decrease in left ventricular (LV) ejection fraction (EF) and conventional electrocardiographic (ECG) signs associated with myocardial structure changes (pathological Q wave, ventricular arrhythmias), and relatively novel and less studied (fragmented QRS (fQRS), early ventricular repolarization (EVR)) and to evaluate their significance for identifying patients with mildly-reduced EF (mrEF).Material and methods. The study included 148 patients who were treated and examined at the Almazov National Medical Research Center. During the ECG analysis, fQRS, EVR, pathological Q wave, and ventricular arrhythmias (VAs) were assessed. Echocardiography data were analyzed. Statistical processing was carried out, including Fisher and chi-squared test, as well as correlation and ROC analysis.Results. Depending on the EF level, patients were divided into three groups: group 1 — patients with reduced EF (rEF) (<40%); group 2 — patients with mrEF (40-49%); group 3 — patients with preserved EF (pEF) (>50%). In the 1st group (with rEF), fQRS was registered in 16 (51,6%) patients, in the 2nd (with mrEF) — in 13 (44,8%), in the 3rd (with EF >50%) — in 16 (18,2%). Pathological Q wave was detected in the 1st group (rEF) in 20 (65%) patients, in the 2nd (mrEF) — in 10 (35%); in the 3rd (pEF) — in 15 (18%) (p<0,001). ROC analysis found that fQRS is more important for identifying patients with mrEF. In the 1st group (rEF), EVR was registered in 2 (6,5%) patients, in the 2nd (pEF) — in 2 (6,9%), in the 3rd (EF>50%) — in 11 (12,5%); the differences were not significant (p=0,5). The relationship of EVR, the number of PVCs and the presence of ventricular tachycardia with EF was not revealed.Conclusion. FQRS is significantly more often observed with a decrease in EF and may be a marker of an mildly-reduced EF. There were no significant correlations between EVR and EF. There was also no relationship between VAs and LV systolic dysfunction.

Aim. To assess the association between changes in interventricular delay (IVD) and response to cardiac resynchronization therapy (CRT) during 24-month postoperative period in patients with quadripolar left ventricular leads.Material and methods. This retrospective non-randomized study included data from 48 patients with implanted CRT devices with quadripolar left ventricular (LV) leads, examined 3, 6, 12, 24 months after operation. CRT responders were considered patients with a decrease in end-systolic volume (ESV) by more than 10% compared with preoperative. To test the hypothesis about the rationale for choosing the maximum IVD when installing the LV lead, the group of patients was divided into two subgroups as follows: one with the maximum IVD (IVDmax, n=24), the other — without this condition (n=24).Results. A correlation was found between changes in IVD and ESV, as well as ejection fraction (EF) in the period of 6, 12 and 24 months after implantation compared to baseline. In the subgroup with IVDmax, the shortening of IVD in the postoperative period is higher at each considered period compared to the second subgroup, and in general, there is a more pronounced decrease in IVD over 24 months. At the same time, 3, 6, 12 months after surgery, patients with IVDmax show a significantly greater decrease in ESV and, accordingly, a greater increase in EF. Prognostic models of CRT response in the long term after implantation were created. Significant predictors were the initial IVD, changes in IVD in the early postoperative period and IVDmax selection. At the same time, not a single factor, taken separately, made it possible to separate responders and non-responders.Conclusion. A greater shortening of the IVD corresponds to a greater decrease in LV ESV and EDV, as well as a greater increase in EF in the long-term postoperative period. The choice of quadripolar LV lead in accordance with the maximum IVD is accompanied by a decrease in the proportion of non-responders, a more pronounced decrease in electrical ventricular dyssynchrony and an improvement in systolic function.
The immediate and short-term degradation of the wood surface in a cement environment measured by AFM
Authors: Li Juan , Kasal Bohumil 
Published: August 2022

AbstractThis study aims to measure the pit torus and border to monitor the immediate and short-term degradation of wood surfaces after the concrete is cast and the cement hydration releases heat. The surface morphology and adhesion force curves were measured by atomic force microscopy during the treatments in saturated calcium hydroxide solutions ranging from 1 h to 27 days. The results showed that the pit torus and pit border showed different degradation processes. The adhesion force was sensitive to the type of the surface chemical components exposed during the degradation, while the surface modulus, deformation and jump-off force ratio were sensitive to the surface structural strength. The surface modulus of the pit torus degraded to 0.61–0.66 of the untreated original (95% CI) after 7-h treatments, and degraded almost completely after 48-h treatments. The surface modulus of the pit border degraded to 0.83–0.95 of the untreated original (CI) after 10 days and to 0.20–0.23 of the untreated original (95% CI) after 27 days of treatments. The treatment temperature 50 °C caused a 10-times faster degradation in the torus modulus compared to the temperature 20 °C.

Published: August 2022

Este estudo objetivou compreender como discentes cotistas de uma universidade federal do sul do Brasil percebem a influência das características/configurações institucionais em seu processo de integração e permanência universitária. Foram realizadas entrevistas semiestruturadas com 10 discentes de três áreas (humanas, saúde, tecnologia). Os dados passaram por análise de conteúdo. Identificou-se a existência de apoios – empréstimo de materiais didáticos, bolsas estudantis voltadas ao auxílio financeiro, isenção no restaurante universitário, serviços de apoio pedagógico e psicológico especializados, diversidade de atividades extracurriculares, etc. Também se verificou a existência de obstáculos – horários restritos de funcionamento em alguns setores/serviços voltados ao apoio estudantil, elitização de processos seletivos para atividades extracurriculares, desconhecimento ou divulgação ineficaz sobre a existência de serviços de apoio pedagógico institucional, falta de oferta de café da manhã no restaurante universitário, etc. Discute-se a necessidade de desconstrução de um processo de “inclusão excludente” por meio de políticas públicas e institucionais que visem um processo formativo com a qualidade adequada a todos os discentes.
KARL SCHMITT AND HANS KELSEN'S DISCUSSION ON THE GUARANTOR OF THE CONSTITUTION IN THE CONTEXT OF THE CONFLICT OF POLITICAL AND LEGAL DOCTRINES
Authors: Ukhanov Anton D. 
Published: August 2022

Aim. To establish common and diverging points of Karl Schmitt's decisionism and Hans Kelsen's pure theory of law, which manifested themselves during the discussion on the guarantor of constitution.Methodology. The approach of the Cambridge School of Conceptual History, described in the methodological works of the political thought historian Quentin Skinner, is used as the methodological basis of the study. The key approach is complemented by the use of special methods, which include comparative, formal-legal, and historical-biographical methods.Results. It is revealed that the discussion about the guarantor of the constitution demonstrates a high degree of antagonism between the political and legal teachings of K. Schmitt and G. Kelsen. These contradictions concern not so much specific political and legal requirements (recognition of the Reich President as the guarantor of the constitution or the establishment of a constitutional court for the same purpose), but theoretical and methodological objectives and interpretations of key concepts on which thinkers base their positions, as well as the argumentative strategies that seem convincing and are used by them to defend their own points of view.Research implications. The theoretical significance lies in the establishment of the factors underlying the contradictions between the doctrines, as well as the role of discussion in the formation of each of them. At the same time, the acuteness of the disagreements revealed during the polemic problematizes the construction of the state-legal theory as a kind of integral structure. In addition to this, it seems that the propositions put forward have significant heuristic potential and, subject to further refinement, can partially be used to explain the development of the history of political and legal thought.

A educação possui papel fundamental na formação humana e nas mudanças comportamentais que visam reduzir problemas ambientais. Este artigo busca identificar as concepções e as distintas práticas pedagógicas acerca do ensino da biodiversidade sob a perspectiva de professores e concluintes do curso de licenciatura em Biologia, verificando a importância dessa temática no ambiente escolar, sua abordagem e a forma com que marcos legislativos documentais, como a Convenção sobre a Diversidade Biológica (CDB), são levados em consideração. Utilizamos uma abordagem qualitativa por meio de entrevistas em profundidade guiadas por questionários semiestruturados, analisados por meio da análise textual discursiva. Os resultados mostram que os sujeitos investigados possuem mais de uma concepção a respeito da diversidade biológica de espécies, ecossistemas e genética. Estes resultados também evidenciam a importância dessa diversidade para a sociedade, por meio de exemplos de boas práticas da educação ambiental, com tentativas de trabalhar os conteúdos com as demais disciplinas. Sugerimos a necessidade de um olhar mais reflexivo em relação à atuação dos cursos de licenciatura ao redor da temática biodiversidade.

Using motivation to improve learning achievement with a chatbot in blended learning
Authors: Chaiprasurt Chantorn , Amornchewin Ratchadaporn , Kunpitak Piyamart 
Published: August 2022

Chatbots have the potential to be used as motivational learning tools, particularly for boosting academic performance. The purpose of this study is to construct a Facebook Messenger chatbot to promote accomplishment through the use of blended learning, guided by the ARCS (attention, relevance, confidence, satisfaction) motivation model that compares how engagement works, and explores the chatbot in terms of its usability. Integrated with Facebook Messenger, chatbot software was designed to answer inquiries based on the chatbot's communication framework. This included course alerts, a gradebook for each student, attendance statistics, and assignment feedback. Using a quasi-experimental research approach, the influence of the chatbot on student motivation and academic achievement was empirically investigated. The trial covered 18 weeks, and the sample comprised 48 students enrolled in a course on Information Technology for Learning. The results suggest that the chatbot increased the learning accomplishment of the students to a considerable extent, and that a motivational setting may lead to a better outcome than a blended learning environment. Overall, our approach produced reliable findings which validated the chatbot's capacity to communicate with students. The students agreed that the chatbot facilitated their learning, but that a few modifications were required in terms of ongoing development.

Managing a classroom consisting of students with different background knowledge in language skills has become difficult for Arabic language teachers in state universities in Sri Lanka, which has led to poor achievement in the four skills of students, in addition to that teachers face difficulty in achieving the desired goal of the lesson during the assigned class. This study aims to expose the current situation of the process of teaching Arabic in state universities in Sri Lanka, to reveal the reality of Arabic language teachers in taking into account individual differences, and to determine the extent of the students’ weak performance of language skills, and to diagnose its causes affecting it. The effect of the cognitive level variable on students’ linguistic achievement and to know the reality of teachers in the issue of taking into account individual differences. The researcher used descriptive quantitative methodology to analyse the data gathered through structured questionnaire and library works by using MS Excel. The study reached several results such as; the current curriculum in the Department of Arabic Studies is not designed in the light of psychological and social principles, and that the classroom may consist of students of different levels in age and knowledge, and there is a lack of interest among teachers with regard to taking into account individual differences. The responsible persons should consider reformulating the curriculum in accordance with modern requirements in light of psychological and social principle.
Putting an End to “Man”: Nature and the Human in Hegel, Becoming-Animal and Abolitionism
Authors: Bednarek Joanna 
Published: August 2022

The article attempts to reconstruct the diﬀerence between the ontologies of Hegel and Deleuze. The question of nature and Man (as diﬀerent from the human animal) in both philosophies can provide crucial insight into the fundamental ontological disparity between the two philosophies. Nature, according to Hegel, is truly external to the idea and (as such) is at the same time a moment in the movement of the concept becoming what it is. Deleuze, in contrast, goes back to pre-Kantian ontology without abandoning the transcendental level of analysis. This enables him to bestow upon nature real externality and to transform the dialectic into a mechanism of opening to the inexhaustible outside, not of conﬁrming the primacy of the concept. The case of becoming-animal demonstrates the political implications of this ontological choice: it can be understood as a way of putting an end to “Man,” an enterprise compatible with abolitionist postulates.
