a single organ, without a clear division into segments. The problem of intestinal anastomotic leakage has not yet been resolved, and its proportion is from 3.4 to 15.3%, with a mortality rate of up to 18.6%. Identification of the anatomical features of different segments of the small intestine and their contents is of practical importance in surgery in terms of prevention of complications. Aim. Identification of morphological features of different segments of the small intestine and their microbiota. Materials and methods. An examination of 26 samples of the small intestine during autopsy was performed. The morphological features of the small intestine, its intraluminal microbiota composition, as well as leukocyte infiltration of the intestinal wall were studied at different distances from the ligament of Treitz. Results. The morphological characteristics of the small intestine are both individual (length) and common (changes in venous architectonics and a gradual decrease in intestinal diameter in the caudal direction). The number and cellular composition of leukocytes in the wall of the small intestine are approximately the same, which provides equal immunological protection regardless of the distance from the ligament of Treitz. The concentration of microbial communities and their qualitative composition change at different lengths of the small intestine, with a gradual increase towards the terminal segment. Changes in the qualitative and quantitative composition of the microbiota in the intestinal lumen do not lead to changes in the leukocyte reaction. Conclusion. When planning and performing a surgical operation, it is necessary to take into account the presence of different volumes and species composition of the bacterial load, as well as the morphological characteristics of different segments of the small intestine.

Of the various articles that have undergone changes and additions in the new Criminal Code, one of them is interesting, namely Article 54 related to forgiveness by judges. However, whether the concept of forgiveness decision by the judge in the new Criminal Code has a position as a decision in the Criminal Procedure Code or the Criminal Procedure Bill. This research uses a normative juridical research method, which examines the problem by referring to positive law. The results of this study indicate the need for additional types of forgiveness decisions in the Criminal Procedure Bill as a form of criminal law reform because the provisions related to the types of decisions in the Criminal Procedure Code and the Criminal Procedure Bill are currently unable to accommodate forgiving decisions by judges. By examining in more depth the concept of forgiveness by the judge, it will appear that neither the Criminal Procedure Code nor the Criminal Procedure Bill contains the type of forgiveness decision.

The importance of maritime development legal politics is because the Indonesian nation until now has not had a national policy on the development of an integrated archipelagic state, weak understanding and awareness of Indonesia as an archipelagic state, has not set the boundaries of territorial waters even though the territorial waters, weak defense and state resilience from the seaside. Based on these problems, efforts to protect and ensure state security by sea are absolute. How is the legal politics of maritime development within the boundaries of territorial waters in Indonesia and how the enforcement of maritime law in Indonesian maritime waters is related to the country's maritime security? This research uses empirical juridical research methods, through tracing and reviewing secondary data, in the form of laws and regulations, academic manuscripts, policy recommendations, and scientific works of experts in the field of maritime development. The results of the discussion of the internationally recognized politics of maritime development law are very important, as a rule that can be used as a reference, especially by countries that have ratified it in determining maritime policy. The government has set various development policies and development of the maritime sector and is still weak in consistency and priority of implementation of these programs. Law enforcement in the maritime sector of Indonesia related to state maritime security is indispensable for the implementation of state maritime security in inland waters, archipelagic waters, Indonesian territorial seas, sea lanes, straits for international shipping of the Indonesian continental shelf, EEZ, and additional zones due to various forms of threats and threats to the Indonesian sea which has abundant natural resource potential and geographical position and strategic geopolitics.

This research discusses the Supreme Court decision Number: 813 K/Pid/2023 regarding the criminal law enforcement of premeditated murder committed by Ferdy Sambo. This decision changed the sentence for convicts from the death penalty to life imprisonment. This penal reduction needs to be studied using a constructivist paradigm. The constructivist paradigm will examine the operation of law in society which is influenced by people's experiences, whether social, religious, cultural, including ideological. The Supreme Court's decision provides legal considerations regarding mitigating reasons for the convict. This is the difference with the decisions of the lower courts. From a constructivist perspective, this is not quite right. It is necessary to state the factors of community experience in making decisions for convicts. Moreover, there was a dissenting opinion by the judge in adjudicating the Supreme Court's cassation decision Number: 813 K/Pid/2023. The difference of opinion is based on legal considerations that the reason for self-defense is forced, the self-respect or honor of the convict does not need to be considered. Then there are allegations of immoral acts whose truth has not been clarified by the convict to the victim. The reality of the experience was not explored enough in the decision, both social factors and environmental factors of the convict.This research discusses the Supreme Court decision Number: 813 K/Pid/2023 regarding the criminal law enforcement of premeditated murder committed by Ferdy Sambo.

The existence of the State Administrative Court is one of the characteristics that shows that Indonesia is a rule of law country. The State Administrative Court has an important role in ensuring the validity of the law in the implementation of state administration, which in this case is adjudicating the actions of officials or state apparatus which are contrary to the principles of good governance and completing the rescue of the KTUN. In the process of resolving the KTUN resolution, the principles of State Administrative Justice are of course used, one of which is the principle of examining legal validity (rechtmatigheid principle) which has an important role in making decisions regarding the release of KTUN. Therefore, this article tries to explain again the essence and influence of the implementation of the principle of legal validity. The writing method used in this research is juridical-normative using a statutory approach and a conceptual approach. This paper uses a normative research method, namely an approach based on legal materials by examining concepts, theories, legal principles and statutory regulations, as well as relevant literature in this paper.

Indonesia is a state of law, where all actions or deeds carried out by each individual or group have been regulated in laws and regulations. The conception of the State of Law or Rechtsstaat is listed in the Explanation of the 1945 Constitution, formulated explicitly in Article 1 paragraph (3) which states that Indonesia is a State of Law. Indonesia is a country that has a diversity of ethnicities and cultures as well as different beliefs but still has one goal, mutual respect and tolerance for every difference that exists. In a group of Betawi people in Bekasi, there is a custom called Uang Pelangkah. Indonesia is a state of law, where all actions or deeds carried out by each individual or group have been regulated in laws and regulations. The conception of NUang pelangkah is money or goods given by the younger brother to his sister to marry first, money pelangkah is a custom that is believed to be hereditary from ancient times to the present. The community believes that pelangkah money is a disaster repellent and as a tribute to an older brother who will be stepped over by his younger brother, the community believes that if a younger brother does not give pelangkah money when going to step over his brother to get married then, a brother will get a mate in a very long time and his family will get a disaster. So the stepping money has become a habit of the Betawi Indigenous people. The purpose of this writing is to find out Betawi customs, namely stepping money in the perspective of Customary Law and Islamic Law and aims to find out how the application of Receptio A Contrario Theory in relation to Stepping Money. This writing is made to facilitate the development of legal and cultural sciences, especially stepping money in Betawi customs in the perspective of Customary Law and Islamic Law. It is hoped that it can be an input for legal practitioners and the community, especially regarding the customs of stepping money. The method that the author makes in this research is normative-empirical, namely combining normative law which is then supported by additional data or empirical elements.

CLINICAL PROTOCOL FOR THE PREPARATION AND ELECTRON MICROSCOPIC ANALYSIS OF THE OBTAINED PRODUCTS OF AUTOLOGOUS MESOCONCENTRATE – PLASMA RICH IN GROWTH FACTORS (PRGF)
Authors: Oshurko Anatolii P. , Oliinyk Ihor Yu. , Kerimova Tetiana M. , Pompii Elina S.
Published: December 2023

Introduction. Ensuring control over regenerative processes by using the patient's blood is a unique concept of an autogenous transplant product, a universal and safe method of application that contains growth factors and cytokines stored in the fibrin matrix and provides stimulating properties of tissue regeneration through the processes of angiogenesis, proliferation, cell migration, and extracellular matrix synthesis.
The aim. To substantiate the effectiveness of the protocol for collecting, preparing, and forming autocellular mesoconcentrate products in the analysis of the results of their electron microscopic examination.
Materials and methods. Based on our own clinical experience of using the Endoret-PRGF technique (Human Technology, BTI, Spain) to collect, prepare, and form autocellular transplant products rationally, we used the method of morphological study of objects using a stream of electrons that passed through thin films under high voltage, allowing us to study the structure of these objects at the macromolecular and subcellular levels – transmission electron microscopy, which contributed to the study of the density (number of occurrences in 10 μm2 ), diameter (Ø) of the formed fibrin fibers in the PRGF – F1 and F2 fractions of mesoconcentrate products, namely, isolating membranes (M) and obturating blocks (B). An equally important step in PRGF technology is to follow the step-by-step instructions for preparing and using autocellular transplants.
Results. Protocol for the collection, preparation, and formation of autocellular transplants using the KMU15 kit (Human Technology, BTI) for the application of the Endoret – PRGF technique, platelet-rich plasma, as a unique and first scientifically proven technique recognized worldwide and patented by the Institute of Human Biotechnology, Spain. The results of the clinical application of mesoconcentrate products, namely isolating membranes widely used in targeted tissue regeneration and obturating blocks, confirm their biological effectiveness. The results of the median (Me) and interquartile range (IQR) during the statistical analysis were obtained, where F1-M = 0.196 (0.176; 0.286) compared to F1-B = 0.344 (0.325; 0.394); F2-M = 0.180 (0.168; 0.214) - F2-B = 0.254 (0.202; 0.338), which gives us the right to assert the reliability of the data set and confirms the quantitative characterization of interfraction differences, and, accordingly, the quality in the sequence of protocol stages.
Conclusions. The protocol for the efficiency of autocellular graft collection and formation is synchronized with the analysis of electron microscopic images characterizing the density and diameter of fibrin fibers, which differ in the fractional products of the mesoconcentrate and are higher in the obturating blocks than in the isolating membranes, indicating its completeness and compliance.
MESENCHYMAL STEM CELLS: EXOSOMES AND CONDITIONED MEDIA AS INNOVATIVE STRATEGIES IN THE TREATMENT OF PATIENTS WITH AUTOIMMUNE DISEASES
Authors: Hladkykh Fedir V.
Published: December 2023

Introduction. Autoimmune diseases are a class of immunopathological conditions heterogeneous in clinical manifestations, characterized by immune disorders that cause the loss of the body's autoimmune tolerance and, as a result, abnormal reactivity of B-cells and T-cells, which leads to damage to own tissues. Today, about 10% of the population suffers from diseases of this class, which are clinically manifested in the form of more than 80 forms of autoimmune diseases.
The aim of the study. Summarize current ideas about the therapeutic potential of conditioned media and exosomes of MSCs in the treatment of patients with autoimmune diseases based on data from open sources of information.
Materials and methods. Publications were selected based on PubMed, Clinical Key Elsevier, Cochrane Library, eBook Business Collection and Google Scholar databases, which covered information on the use of conditioned media and MSC exosomes in the treatment of diseases of premature newborns using the
Keywords:
mesenchymal stem cells, conditioned media, secretion, autoimmune diseases.
Results. The technical complexity and high costs associated with the production and regulatory approval procedures of MSC therapy create barriers to their clinical use. Studies have shown that the cell-free secretome of MSCs, which consists of a wide range of growth factors, cytokines, chemokines and extracellular vesicles, exhibits a pluripotent effect. Today, extracellular vesicles are classified according to their diameter into apoptotic bodies (>1000 nm), microvesicles (100–1000 nm) and exosomes (30–150 nm). Exosome activity can be easily manipulated by preconditioning MSCs, by simply adding cytokines or chemicals to the culture medium, by introducing gene modifications, or by using hypoxic culture conditions. A number of studies have demonstrated the comparable effectiveness of conditioned media and MSC exosomes in the treatment of patients with autoimmune diseases.
Conclusions. Exosomes and conditioned media with MSCs have the potential to replace cell therapy or serve as a comparable clinical strategy to biological therapy in neonatology. MSC preconditioning will allow modulating the therapeutic effects of exosomes and will become the basis for establishing recommendations and standards for effective and safe cell-free therapy.
Jazz Improvisation and Creolizing Phenomenology
Authors: Matarrese Craig
Published: December 2023

Jazz improvisation requires a set of phenomenological practices, through which musicians confront their own sonic situatedness. Drawing on writings from Paget Henry, Mike Monahan, and Storm Heter, these phenomenological practices can be characterized as creolizing, and can reveal a sense in which, as Sidney Bechet says, music gives you its own understanding of itself. Specifically, improvising musicians engage their own situatedness by slowing things down, and through repetition. Bass players can listen through other players’ hands, and audiences can hear more of what's happing in jazz by understanding the ways musicians practice.

Published: December 2023

No ensino de Biologia o ensino tradicional ainda é o método mais usado na educação brasileira, principalmente no ensino de jovens e adolescentes, o que provoca um desinteresse da maioria dos discentes, pois a disciplina de Biologia é considerada uma das mais complexas abrangendo diversos conteúdos de difíceis compreensão e entendimento. Os jogos didáticos são a melhor estratégia para complementar o tradicionalismo, principalmente em escolas escassas de laboratório de ciências. Visto que, a ludicidade é aplicada de maneira mais simples e objetiva, além se ser o método que os alunos mais gostam, ela também desenvolve a liderança, o raciocínio lógico e a interação entre alunos e professor. Para a comprovação dessa teoria a pesquisa foi feita com os estudantes do 3º ano “A’’ da Escola de ensino Médio em Tempo Integral Simão Ângelo localizada no município de Penaforte-CE. O objetivo desta pesquisa é elevar consideravelmente a média geral da turma e tornar o conteúdo de Biologia mais divertido e prazeroso, para isto, foram necessárias pesquisas quantitativas e qualitativas. Foram usados, dois Jogos didáticos o tabuleiro educacional inspirado nas regras do tabuleiro indiano e um jogo virtual chamado Kahoot que possibilita a elaboração de perguntas com limite de caracteres, as quais os estudantes acessam e respondem as questões ao mesmo tempo, aquele que acertar o maior número de questões e mais rápido ganha o jogo. A implementação de jogos lúdicos realmente obteve resultados positivos não somente na média dos educandos, mas também despertou o interesse pela disciplina. Contudo conclui-se que os jogos lúdicos são eficazes no ensino de Biologia, ensina muito, porém não ensina tudo mas facilita a o aprendizado e a fixação do conteúdo.

There is a potential to enhance both the efficiency and the quantity of explosives in limestone excavation utilising deck charge patterns in the Aruwakkalu limestone quarry in Sri Lanka. To achieve this a series of combinations with ANFO and deck charge patterns were simulated using a numerical analysis software named JKSimblast – 2D bench. This study entails simulating and validating the existing blasting geometry in the rock blasting practice. The fragmentation curves of the real world blast events were analysed and plotted using an AI platform called “Streyos”. Subsequently, the blasting geometry was optimised by adjusting the spacing and burden with different charge amounts. A comparison was made between the explosive energy distribution figures of the simulated blast with optimised blasting geometry and the deck charging blast series. To simulate the limestone condition for the rock mass, throughout different simulations, the rock specific gravity (SG) was defined as 2.6. Optimised spacing and burden for a 10.3 m deep and 72 mm diameter blast hole pattern were found as 2.9 m and 2.4 m respectively, ensuring favourable conditions with controlled ground vibration (5 mms-1) and air blast overpressure (120 dB). The optimal configuration for minimising boulder formation in the upper section of the hole was 23.17 kg of ANFO quantity per hole with a two-charge deck pattern.

Wildfires and extreme precipitation scenarios are an increasing trend in the global context. Elevated risks of floods are expected to occur due to fire-induced land cover alterations. Hence, it is important to identify the impact of wildfire upon extreme runoff scenarios, under changing climate. This study focuses on the impact of the 2018 Ranch fire and the possibility of downstream flood risk in the Lake County of North - Central California. The soil and water assessment tool (SWAT) is used to estimate potential extreme flood scenarios brought on by high precipitation after wildfires downstream of Lake County. Using hydrological and meteorological data from 2000-2018, the SWAT model is set up and calibrated on a daily and monthly basis. Model calibration was performed after identifying 9 sensitive parameters, including the soil conservation service curve number (SCN-CN), and the model for pre-fire conditions agreed well with R2=0.83, NSE=0.81, and PBIAS=-17.8 values. The soil conservation service (SCS) curve number, wildfire burn severity, and land use are considered in determining the variation of discharge under the post-fire condition. Further research can be used to identify probable flood scenarios even in the context of post-fire low precipitation levels and to enhance simulation outcomes under various parameter modifications.

A dam is a structure constructed across a river or stream to store water upstream from the obstruction. Dams are susceptible to damage for various reasons, which can lead to many catastrophic disasters. Therefore, identifying the dam's structural failures prior to a disaster is crucial. Drilling can be used for dam failure identification. But it is costly and destructive. Integrated geophysical methods have always helped in identifying subsurface features. In the current investigation, the applicability of ground penetrating radar (GPR) to detect potential failures in earthen dams was assessed. The Uyanwatta Lake earthen dam was selected as the study area during this investigation, considering the reported water leakage in this dam. A GPR survey was conducted with 100 MHz and 300 MHz antennas along five survey paths. Those are the top of the dam, 1.5 m below the top of the dam, and three distinct paths for the lake's spill. During the interpretation process, clay layers, fractured zones, gravel layers, and water seepage areas were identified. Those water leakage areas indicate that there has been a leak in the dam. Those results were compared with exploratory drill hole data from the Uyanwatta Lake Dam. Drill hole data has only presented information about the rock types present in the dam. But GPR data was able to provide information on loose sediments in the shallow depths of the dam as well. That indicates GPR data has the potential to provide additional information related to earthen dams.

Water hyacinth (WH) is an invasive aquatic plant that has established its presence in tropical and subtropical regions around the globe. Its widespread existence has resulted in societal, economic, and ecological impacts that are mostly intolerable. Understanding and monitoring the spatial and seasonal dynamics of WH in the respective environments could provide insights to mitigate its environmental impact. This study attempts to identify seasonal patterns of WH within north Bolgoda Lake over four years (2019-2022). The methodology includes a pixel-based random forest (RF) classification utilising five distinct spectral indices in conjunction with raw Sentinel-2 spectral bands, operationalised through the Google Earth Engine (GEE) platform. The aerial imageries were classified using Esri ArcGIS Pro software. The outcomes of this study indicate an increase of WH proliferation during the wet season (May-November) over the dry season (December- April) with an overall accuracy of 82% for aerial imagery and 98% for satellite imagery. Data fusion techniques are proposed to overcome the limitations of employing two different forms of remote sensing data individually. Despite the challenges, this study reveals important insights into the scalability of input data to specific requirements and under restricted conditions.

This research paper investigates the potential impact of hill shade on tea yield at the Dambatenne tea estate using unmanned aerial vehicles (UAVs). Drones were used to take high-resolution aerial photos of the location that was selected. The data were processed using Pix4D software to generate accurate 3D surface models, ortho mosaic maps, and vegetation indices. Additionally, the main goal of this study was to evaluate the impact of hill shade on tea yield. By analysing the obtained data, including vegetation indices derived from the multispectral imagery, the correlation between hill shade and tea yield was examined. Various mapping techniques and statistical analyses were employed to investigate this relationship. The findings suggested that there may be a relationship between hill shade and tea yield and that different levels of shading brought on by topographic characteristics may influence the development and production of tea. The findings from this research contribute to the understanding of how hill shade affects tea yield and provide insights for sustainable tea estate management practices. The results of this study are significant for tea estate owners and managers, as it highlights the importance of considering hill shade factors in optimizing tea cultivation and maximising yield.

In recent years, there has been growing interest in geopolymer cement as a more sustainable alternative to traditional concrete. Metakaolin-based geopolymers have a high capacity to immobilise radioactive cations such as Cs+ and Sr2+ via an ion exchange mechanism. In the meantime, the geopolymer has a high potential to solidify organic liquid waste and has been considered for developing porosity-controlled materials. However, the interaction mechanism between organic liquid and metakaolin-based geopolymer has not been fully understood. In this study, the appropriate control of organic liquid in the geopolymer has been studied. Firstly, alkali-activated solution (K2O:SiO2:H2O molar ratio of 1:1:13) was mixed with the lubricant (FBK Turbine 32) and cationic surfactant (CTAB) to form an emulsion. Then metakaolin-based (Sobueclay) geopolymers were synthesised in the emulsion (Al: Si molar ratio of 1:1). The interaction mechanism between the oil with emulsion and geopolymer (with or without surfactant) was evaluated using the zeta potential, paste slump flow, SEM, and compressive strength. The metakaolin-based geopolymer could not solidify the oil. However, the geopolymer can successfully solidify oil content with the help of a surfactant that changes the surface of the oil from negative to positive, allowing it to interact with the opposing surface of the geopolymer. However, the compressive strength of the resulting composite decreased as the oil content increased due to an increase in porosity, and as the hydration products filled the pores over time, the strength increased. These findings suggest that geopolymer could be a promising solution for solidifying oil. However, careful consideration must be given to the porosity induced by the presence of oil to ensure that the resulting composite has sufficient strength for its intended application.

Landslides being an abundant source of risk prevailing worldwide, the mountainous regions in the central part of Sri Lanka, experience numerous slope failures throughout the year. Many such slope failures have been reported following extreme rainfall events. Comprehension of the causative factors underlying these hazardous events hold much significance in developing control strategies for future disaster mitigation efforts. Numerical modelling and machine learning are distinct approaches that are widely being used in simulating hydrogeological processes and other environmental phenomena leading to disasters, the objective of this study was to investigate the use of an integrative approach of these two disciplines in evaluating the risk of landslide susceptibility with specific application to a site near Uma Oya catchment, Sri Lanka. The model incorporates a finite difference scheme for groundwater modelling coupled with slope stability evaluations using raster-based grid operations in GIS, analysed for two historical landslide cases within the region. The gradient-descent optimisation algorithm was adopted in optimising the groundwater model in which the results were in good agreement with the true observations, where the predicted water table levels exhibited a 78% recovery rate of true positives, justifying the usability of the adopted research framework in future disaster reduction endeavours.
Conocerlos por sus palabras: los lectores argentinos del Fondo de Cultura Económica a través de su correspondencia (1945–1955)
Authors:   El Colegio de México, Guzmán Anguiano Francisco
Published: December 2023

The purpose of this article is to outline the characteristics of the reading public of the Fondo de Cultura Económica in Argentina between 1945 and 1955. Based on the correspondence exchanged by various Argentine readers with the branch and headquarters of the publisher in Mexico, it analyzes both the social profile that characterized this community and the capacity for action they had to satisfy the requests they expressed through their letters and expectations regarding what the reading exercise represented for them, thereby seeking the consummation of different goals and purposes. It is concluded that these actors had some capacity to symbolically subvert the roles within the book circuit, especially when interests and purposes were combined between them and the publisher, in addition to the fact that reading acquired a social significance related to human progress within a civilizational development and the strengthening of identity relations between national communities.
Універсальний символ хреста: геометричний мотив і релігійний символ. Вивчення порівняльної естетики
Authors: Монд-Козловська Весна
Published: December 2023

Мета статті. Це порівняльне дослідження має намір підтвердити істинність того, що форма й символ хреста є супутниками людини з часів виникнення людської цивілізації. По-перше, на розгляд буде представлено найбільш раннє вираження ідеї хреста як розумового концепту людини. Про це свідчать знахідки спеціалістів з культурної антропології всього світу, в яких наголошується на доісторичному знаку тетрагамадіону, або фільфоту, свастики. По-друге, дослідження тяжіє до розвитку символіки християнського хреста, який спочатку не мав фігури розп’ятого Божого Сина, проте яскраво демонстрував своє безпосереднє походження від місця грудей священика в єврейському храмі, що називалося урім і туммім, світло й досконалість на івриті. Розглядаючи форму християнського хреста, необхідно зважати на дві відмінні семантики та ментальні концепти його найпоширеніших зображень, а саме на грецькі й римські варіанти форм, що демонструють різні концептуальні та естетичні вираження того ж самого предмета.
Результати дослідження. Предмет дослідження розглянуто з міждисциплінарної точки зору, що охоплює перспективні хореологічні дослідження з семіотики, логіки, історії мистецтва та культурології. Проте, враховуючи повсюдне асоціювання хреста з викупною жертвою Ісуса, певні висновки зроблено завдяки опису двох надзвичайних мистецьких творів, а саме: Каталонський рух XII століття під назвою Majestat Batilo (Іспанія); Рух XIIІ століття з Камень-Поморського (Польща).
Наукова новизна. Нове дослідження символіки хреста, проведене в аспекті порівняльного підходу, дозволяє глибше зрозуміти появу цього давнього знака в культурі, долучаючи знання з точних наук, зокрема мінералогії або ж астрофізики. Подальші передумови дослідження припускають, що динаміка хреста може бути конститутивним принципом формування матерії.
Висновки. Дослідження має на меті заохотити до подальшого вивчення сакрального значення цього первісного знака, що виходить далеко за межі будь-якої конкретної конфесії.
Renaissance der Weltbilder? Wissenssoziologische Überlegungen zur Genesis und Permanenz von Ordnungsvorstellungen
Authors: Fischer Peter
Published: December 2023

Der Aufsatz zeigt die Ursprünge des modernen Weltbilds auf und setzt dies in Beziehung mit der Weltanschauungsanalyse, die vor allem in den Geisteswissenschaften und der Wissenssoziologie im ersten Drittel des 20. Jahrhunderts an Bedeutung gewann. Daraufhin werden Gründe für das Verschwinden der Diskussion um dieWeltbilder gesucht. Demgegenüber wird von einer Permanenz von Weltbildern ausgegangen, die jedoch nur unter bestimmten Voraussetzungen diskussionswürdig erscheinen. Solche Voraussetzungen sind in der Gegenwartsgesellschaft gegeben.
Kommunalpolitik in Deutschland: Mehr Konflikt als Harmonie?!
Authors: Holtkamp, Lars , Garske Benjamin Garske
Published: December 2023

Bürger:innen haben heute eine starke Position im kommunalen Willensbildungs– und Entscheidungsprozess inne. Neben Kommunalaufsicht, Koalitionspartner:innen oder (Oppositions-)Parteien kann auch die Beteiligung von (zivil-)gesellschaftlichen Akteur:innen je nach Vetospielerdichte und Handlungsrahmen Vetopositionen oder Verhandlungszwänge auslösen. Lokale Handlungsspielräume werden mitunter eingeengt. Die möglichen Ursachen sind Thema dieses Textes.

Die Fünfte Jahreszeit als Wirtschaftsfaktor
Authors: Rusche Christian
Published: December 2023

Es gibt in ganz Deutschland die Tradition, vor dem Beginn der Fastenzeit vor Ostern noch einmal zu feiern. Karneval, Fasching, Fasnacht usw. beginnen am 11.11. eines Jahres und enden am Aschermittwoch des Folgejahres. Dieser Zeitraum wird Session genannt und variiert in der Länge, was einen Einfluss auf die wirtschaftlichen Effekte hat. Diese wirtschaftlichen Effekte zu quantifizieren ist nicht trivial. Für die letzte Session 2022/23 variieren sie zwischen 1,8 und 2,8 Milliarden Euro für ganz Deutschland. Davon entfallen mehr als 40 % auf Nordrhein-Westfalen und allein auf Köln rund 23 %. Relativ gesichert ist, dass mehrere Zehntausend Arbeitsplätze an den Feierlichkeiten hängen.

Der Text formuliert eine Anfrage: Wie werden Denkmalschutz, kulturelles Erbe und kulturelle Teilhabe auf die Agenda (politischen) Lernens gesetzt, um zur Verwirklichung der in Verfassung und völkerrechtlichen Konventionen verbürgten Rechte und Pflichten sowie in Resolutionen formulierten menschheitlichen Selbstverpflichtungen beizutragen?
Zeitenwende(n) und moralische Weltordnung. Reflexionen zur Menschenrechtsbildung
Authors: Böhm Otto
Published: December 2023

In der„Zeitenwende“ werden die menschen- und völkerstrafrechtlichen Normen und Ordnungsvorstellungen erschüttert, die die internationalen Beziehungen seit dem Ende des Kalten Krieges geprägt haben. Die normsetzenden und verteidigenswerten Institutionen werden jetzt noch häufiger, auch in der politischen Bildung mit Schulklassen, Bundeswehr- oder Polizeigruppen als „zahnlose Tiger“ bezeichnet werden. Was sollte an dieser dissonanten Wahrnehmung überprüft und modifiziert werden? Hier einige Überlegungen zur Frage nach (Welt)Ordnung und Normgeltung in der politischen Bildung.
