Makroekonomik Değişkenlerin Kamu Harcamaları Üzerindeki Etkisi: Wagner Yasası Geçerliği
Authors: MUHARREM Şamil , UYSAL Doğan
Published: May 2023

Bu çalışmanın amacı makro değişkenlerin kamu harcamaları üzerindeki etkisinin olup olmadığını araştırmaktır. Bu bağlamda 2006-2020 dönemine ilişkin 11 AB üyesi olan OECD ülkesi seçilerek kamu harcamalarıyla makro değişkenler arasında ilişkinin olup olmadığı belirlenmeye çalışılmıştır. Wagner Yasası’nın geçerliğini; yani ekonomik büyümeden kamu harcamalarına doğru ilişkinin belirlenmesinde Panel Nedensellik test yöntemi kullanılmıştır. Bazı ön koşullar sağlandıktan sonra yapılan Panel Nedensellik test sonuçlarına göre, kamu harcamalarıyla ekonomik büyüme arasında tek yönlü bir ilişkinin olduğu gözlemlenmiştir (Keynesyen hipotezi geçerlidir). Diğer taraftan kamu harcamaları ile enflasyon oranı arasında çift yönlü nedensellik ilişkinin olduğu görülmüştür. Araştırmadan elde edilen son sonuç ise, enflasyon oranı ile iktisadı büyüme arasında karşılıklı nedensellik ilişkisinin olduğudur.

This clinical case shows the diagnosis of 22q11.2 Deletion Syndrome in an 11-year-old child with symptomatic hypocalcemia and emphasizes the possibility of a late diagnosis of 22q11.2 Deletion Syndrome.
Distorted Korean Idol’s Scandal, Deceitful Media, and The Role of Forensic Linguistics
Authors: Zulfie Vivian , Asrumi Asrumi , Sariono Agus
Published: May 2023

A celebrity’s scandal can be an enthralling theme for the media to produce news, either factual or fabricated. This research primarily focuses on distorted content or media manipulation to report it. It explores the correlation between misleading news and the motives behind twisted reality. The method used in this research is a descriptive qualitative method through the lens of the forensic linguistics approach, supported by Villa’s interpretative pragmatics (2010). The collected data were from selected sources of distorted media reporting, especially about a highly considered Korean singer’s crime, known Seungri of Bigbang. His charge was not direct link with sexual abuse and systematic drugs, which is in fact unrevealed wealthy people committing them. Even nonconsensual disclosure of sexually-explicit videos was committed by other celebrities. Yet, the media fraudulently blended and misrepresented Seungri as the key figure of the scandal in a club named ‘Burning Sun’. Society was misled to hate and blame him. This research shows that passive constructions, lexical references, and subject matters of the texts become linguistic evidence of fact distortion. Manipulating celebrity’s scandal is driven by political goals, such as creating mistrust and bewildering larger audiences, especially in South Korea about proving the justice system as the actual culprits are withdrawn. This research is noteworthy since there are interwoven claims of the power of media to wriggle out of legal punishments after spreading distorted facts. Hence, it implies that pragmatics is applicable and efficacious to prove the case. It leads to defamation by media, correlated with forensic linguistics. To reveal the distorted facts by deceitful media, this study expectantly contributes in enhancing social awareness of the truth behind blatant public outrage and its social consequences.
Domestic workersâ€™ lived realities of empowerment and disempowerment within the South African labour legislative context: Two sides of the same â€œcoinâ€
Authors: Marais Christel , Van Wyk Christo
Published: May 2023

South Africa is heralded as a global ambassador for the rights of domestic workers. Empowerment, however, remains an elusive concept within the sector. Fear-based disempowerment still characterises the employment relationship, resulting in an absence of an employee voice. The dire need to survive renders this sector silent. This article explores the role that legislative awareness can play in the everyday lives of domestic workers. By means of a post-positive, forwardlooking positive psychological and phenomenological research design the researchers sought to access the voiced experiences of domestic workers within their employment context. Consequently, purposive, respondent-driven selfsampling knowledgeable participants were recruited. In-depth interviewing generated the data. The distinct voice of each participant was noted during an open inductive approach to data analysis. Findings indicated that empowerment was an unknown construct for all participants. They lacked the confidence to engage their employers on employment issues. Nevertheless, domestic workers should embrace ownership and endeavour to empower themselves. This would sanction their right to assert their expectations of employment standards with confidence and use the judicial system to bring about compliant actions. The article concludes with the notion that legislative awareness could result in empowered actions though informed employee voices.

Authors: Strydom Nadia , Schultz Cecile , Bezuidenhout Adele
Published: May 2023

As high turnover is costly and disruptive, all organisations aim to retain talented employees. Talented employees give organisations a competitive advantage in the complex business environment of today. The aim of this article is to report on the employeesâ€™ perceptions of talent management retention at a labour organisation in Gauteng. The population comprised 317 permanent staff members, and a convenience sample of 162 was used. A principal factor analysis was employed to determine the main factors, namely, dedication to staff and dedication of staff. Descriptive statistics were used to determine the perceptions of staff members on these two factors. In conclusion, recommendations are offered to labour relations practitioners on how human resource practices can contribute to the fair treatment and retention of talented employees in an organisation.
Examining the entry of Walmart into South Africa: A stakeholder management perspective
Authors: Bonakele Tembinkosi , Beaty Dave , Rasool Fathima , Kriek Drikus
Published: May 2023

The recent entry of the US multinational Walmart into South Africa has proved to be a source of controversy. Key stakeholders in South Africa objected to the merger and attempted to block it unless certain conditions were met. The aim of this study was to examine the controversy and the conditions surrounding the merger. The research employed a qualitative archival analysis to examine publicly available sources of information with regard to the merger. The findings revealed key stakeholdersâ€™ concerns that Walmartâ€™s entry would lead to an increase in imports which would displace local producers, increase unemployment, marginalise trade unions and lower labour standards unless certain conditions were met. The results also revealed problems relating to the firmâ€™s primary focus on â€œbusinessâ€ while neglecting â€œpublic interestâ€ issues, naively relying on their â€œlocal retailerâ€ to manage key stakeholders, and assuming that their perceived controversial reputation regarding treatment of trade unions and their views about unemployment as well as the controversies surrounding their history of entry into other global markets would not have the major negative impact it did on stakeholders in South Africa.
Return-to-work experiences of female employees following maternity leave
Authors: Brand Heinrich , Barreiro-Lucas Judite
Published: May 2023

Corporate culture seemingly does not encourage talented women to return to the workplace or continue to operate effectively in the workplace, while managing their domestic responsibilities. This has a direct influence on the progression of talented women to senior positions and their retention in those positions (Baggallay 2011).While the above statement may be a narrow view, considering shifts in many companies' policies which aim to support work-family balance, there are still many underlying concerns regarding working mothers.The primary purpose of this study is to identify common themes arising from the return-to-work experiences of female employees following maternity leave in South Africa.The results of this study revealed that despite viewing work positively, the participants in the study found the return-to-work experience after childbirth difficult. A significant change in the attitudes of the participants towards their careers after childbirth was also identified. This change is not necessarily negative and should not be interpreted as an indication of loss of interest by the employees in their careers. It does, however, highlight the need for adequate management of the whole process from â€œworkplace pregnancyâ€ to return to work of female employees.Employers open to the evolution of best practice for maternity leave will attract and retain high-calibre female talent.

Critical Assessment of pH-Dependent Lipophilic Profiles of Small Molecules for Drug Design: Which One Should We Use and In Which Cases?
Authors: Zamora Ramírez William J. , Bertsch Aguilar Esteban , Suñer Sánchez Sebastián , Pinheiro Silvana
Published: May 2023

Lipophilicity is a physicochemical property with wide relevance in drug design and also applied in areas such as food chemistry, environmental chemistry, and computational biology. This descriptor strongly influences the absorption, distribution, permeability, bioaccumulation, protein-binding, and biological activity of bioorganic compounds. Lipophilicity is commonly expressed as the n-octanol/water partition coefficient (PN) for neutral molecules, whereas for molecules with ionizable groups, the distribution coefficient (D) at a given pH is used. The logDpH is usually predicted using a pH correction over the logPN using the pKa of ionizable molecules, while often ignoring the ionic partition (PI) because of the challenge of predicting the partitioning of the charged species. In this work, we studied the impact of PI on the prediction of lipophilicity of small drug-like molecules by modeling 225 logDpH of a set of experimental values using both the formalism that takes into account a pH correction (see Eq. 1) and the one considering the partition of ionic species (see Eq. 2). Our findings show that a better calculation is obtained by considering the ionic partition while ignoring its contribution can lead to inadequate computational predictions. In this context, we developed machine learning algorithms to determine in which cases the PI should be considered. The results indicate that small, compact, and hydrophobic molecules with a higher likelihood of being in their ionic state at specific pH values, were better modeled using Eq. 2. Finally, we validated our findings using a test and external set where the logistic regressions, random forest classifications, and support vector machine models predicted the better formalism to determine the logDpH for each molecule with high accuracies, sensitivities, and specificities.

Published: May 2023

Three novel bis-dansyl derivatives bearing a sulfur bridge have been synthesized and fully characterized. Their photophysical characterization has been studied in solution as well as in the solid state. All compounds exhibit fluorescence emission with quantum yields up to 60%, which vary significantly depending on the solvent used, and the inherent molecular structure. Moreover, these compounds demonstrate positive solvatofluorochromic behaviour emitting from bluish-green to yellow. Kamlet-Taft studies were performed to understand the solute-solvent interactions better. Due to the intrinsic characteristics of the compounds, efforts were made to understand their potential usefulness for environmental remediation, and thus metal ion sensing studies were investigated. Compounds L1 and L2 showed high sensitivity to Cu2+ and Hg2+ ions and were found to modulate their emission extensively, with L2 capable of detecting and quantifying up to 4 µM of Hg2+. Considering the solid-state emission of these compounds, the application towards temperature sensing was put forth. L3 was found to quench its emission linearly with temperatures up to 170 ºC. Several doped polymer thin films were fabricated, which served as a platform to establish a linear relation with temperature beyond their melting point. Polymethylmethacrylate (PMMA) films emitted up to temperatures of 218 ºC, which could be fully restored at room temperature. These results suggest the potential application of these bis-chromophoric compounds as molecular thermometers.
Environmental and Nuclear Quantum Effects on Double Proton Transfer in Guanine-Cytosine Base Pair
Authors: Angiolari Federica , Huppert Simon , Pietrucci Fabio , Spezia Riccardo
Published: May 2023

In the present work, we investigate the double proton transfer (DPT) tautomerization process in Guanine-Cytosine (GC) DNA base pairs. In particular, we study the influence of the biological environment on the mechanism, the kinetics and thermodynamics of such DPT. To this end, we present a molecular dynamics (MD) study in the tight-binding density functional theory framework, and compare the reactivity of the isolated GC dimer with that of the same dimer embedded in a small DNA structure. The impact of nuclear quantum effects (NQEs) is also evaluated using Path Integral based MD. Results show that in the isolated dimer, the DPT occurs via a concerted mechanism, while in the model biological environment, it turns into a step-wise process going through an intermediate structure. One of the water molecules in the vicinity of the proton transfer sites plays an important role as it changes H-bond pat- tern during the DPT reaction. The inclusion of NQEs has the effect of speeding up the tautomeric-to-canonical reaction, reflecting the destabilization of both the tautomeric and intermediate forms.
CONFPASS: fast DFT re-optimizations of structures from conformation searches
Authors: Lam Ching Ching , Goodman Jonathan M.
Published: May 2023

CONFPASS (Conformer Prioritizations & Analysis for DFT re-optimisations) has been developed to extract dihedral angle descriptors from conformational searching outputs, perform clustering and return a priority list for DFT re-optimisations. Evaluations were conducted with DFT data of the conformers for 150 structurally diverse molecules, most of which are flexible CONFPASS gives a confidence estimate that the global minimum structure has been found, and based on our dataset, we can have 90% confidence after optimizing half of the FF structures. Re-optimizing conformers in order of the FF energy often generates duplicate results; using CONFPASS, the duplication rate is reduced by a factor of two for the first 30% of the re-optimisations, which includes the global minimum structure about 80% of the time.
Predicting nearest neighbor free energies of modified RNA with LIE: Results for pseudouridine and N1-methylpseudouridine within RNA duplexes
Authors: Dutta Nivedita , Sarzynska Joanna , Deb Indrajit , Lahiri Ansuman
Published: May 2023

Pseudouridine and N1-methylpseudouridine are the key modifications in the field of mRNA therapeutics and vaccine research. The accuracy of the design and development of therapeutic RNAs containing such modifications requires the accuracy of the secondary structure prediction, that depends on the nearest neighbor (NN) thermodynamic parameters for the standard and modified residues. The development of such NN thermodynamic parameters requires expensive and time-consuming experimental studies. There were some earlier attempts to predict the NN free energies of modified RNA using computational methods but those are either computationally expensive or not accurate enough. Here, we propose a new protocol based on MD simulations, which is able to predict the NN free energy parameters (ΔG◦37) for U-A, Ψ-A and m1Ψ-A pairs in general agreement with the recent experimental reports. We report the NN thermodynamic parameters for different U, Ψ and m1Ψ base pairs, which might be helpful for a deeper understanding of the effect of these modifications in RNA. The presence of m1Ψ resulted in more stable NN pairs compared to those containing U or Ψ. The predicted NN free energy parameters in this study are able to closely reproduce the folding free energies of duplexes containing internal Ψ for which the thermodynamic data were available. Additionally, we report the predicted folding free energies for the duplexes containing internal m1Ψ.

Teaching and learning activities in South African schools are a focus of several research on the use of Information and Communications Technology (ICT) resources during the COVID-19 crisis. However, more studies are required to examine how the school principals and the parent-members of the School Governing Bodies (SGBs) used the ICT tools to undertake communication on school governance activities during the COVID-19 lockdown. In the wake of the COVID-19 crisis in South African schools, this study examined the use of ICT technologies for decision-making communications relating to issues of school governance between the principals and the SGBs. Utilising a quantitative research methodology, information was gathered from 126 school principals who were chosen at random from the Buffalo City Municipality (BCM) in East London, South Africa. The data analysis method employed was descriptive statistics. The findings showed that the majority of SGB parent members had basic ICT skills, could read and write, used ICT tools like smartphones, voice calls, and SMS messaging, which enabled them to interact with school principals and take part in decision-making related to school governance activities during the COVID-19 crisis. The participants described some of the difficulties associated with their choice of ICT tools, including broken smart phones, a lack of expertise with WhatsApp and Telegram, and slow message answers. The study concludes that the SGBs need to align their school policies with the Fourth Industrial Revolution (4IR) and adopt more ICT platforms for effective communications, governance, teaching, and learning activities in the new normal. It also recommends that, school principals and other SGB members still need to be trained and retrained for the use of ICT tools for efficient virtual or online participation in meetings; and there is also a need to equip SGB members with digital devices such as tablets, laptops, smartphones, and internet data subscriptions to encourage their participation in meetings from homes, offices or any other locations outside of school premises.

The South African government has developed and incorporated African Indigenous Knowledge (AIK) in the school curriculum however, efforts to integrate AIK in teaching and learning have not yielded the desired results. The study, sought to investigate how AIK is integrated into teaching using Ubuntu values and the implications on teaching and learning in the classroom. Premised on Ubuntu theory, the study adopted an integrated literature review approach, and a comprehensive electronic search was done which led to the discovery of articles that are relevant to the study. A total of 36 out of 54 articles published between 2010-2021 were selected and reviewed. The findings from the literature revealed that much research has not been done to develop strategies that assist teachers to integrate AIK into their lessons. The data also showed that there was a lack of professional teacher development programs meant to equip teachers teaching AIK with the necessary pedagogical skills required in their classrooms. The study concluded that the integration of AIK in teaching and learning at classroom level was still not adequate. The study, therefore, that more continuous professional teachers' development programs be implemented on a regular basis while adopting strategies used to integrate AIK in teaching and learning.

Published: May 2023

İş kazalarının temel nedenlerinden birinin çalışanların güvensiz davranışları olduğu bilinmektedir. Buradan hareketle çalışanların güvenli davranışlarının iş kazalarını azaltmada büyük rol oynayacağı açıktır. Araştırmanın amacı, bir ilaç firmasındaki çalışanların güvenlik kültürü ve güvenli davranış düzeylerinin belirlenerek, güvenlik kültürünün güvenlik davranışı üzerine etkisinin değerlendirilmesidir. Bu tespitler de kurumların davranış odaklı güvenlik yönetim sistemi kurmalarını sağlayacaktır. Çalışma, Tekirdağ ve Kocaeli illerindeki bir ilaç firmasının 3 ayrı tesisinde 610 çalışanın katılımıyla anket uygulayarak gerçekleştirilmiştir. Çalışanların %61.14’ü kazaların nedenlerinin çalışanın güvenli (emniyetli) olmayan davranışı olarak yanıtlamışlardır. Ayrıca güvenlik kültürünün, yönetimin sürdürülebilir
güvenlik desteği, çalışma alanı-iş çevresi ve güvenlik farkındalığı olarak üç ayrı faktör başlığı altında toplandığı belirlenmiştir. Regresyon analizi sonucuna göre, güvenlik kültürünü en iyi açıklayan faktör gruplarının, çalışma alanı-iş çevresi ve güvenlik farkındalığı olduğu görülmüştür. Yine regresyon analizine göre, güvenli davranışı etkileyen en önemli faktörün ise güvenlik uyumu olduğu ve üç önemli güvenlik kültürü faktörünün ise güvenlik uyumu üzerine etkisinin %39 civarında olduğu belirlenmiştir. Kadercilik algısı ile herhangi bir faktör arasında %95 anlamlılık düzeyinde bir ilişki olmadığı bulunmuştur. Bu durum bize kadercilik algısını açıklayan faktörün regresyon analizi için kullanılamayacağını göstermiştir. Çalışma sonuçları doğrultusunda, çalışanların güvenli davranışlarının arttırılması için güvenlik uyumu kapsamında güvenli davranışların alışkanlığa dönüştürülmesi gerekmektedir.

Corporate governance is highlighted as an important aspect of developing economies. The literature well explained the relationship between corporate governance and capital structure, but little is known about the role of debt as a takeover defense and disciplinary tool, particularly for a debt-based economy such as Pakistan. This study used data from 173 non-financial firms listed on a stock exchange in Pakistan from 2008 to 2017. For the empirical investigation, the study incorporated the Orthogonal Generalized Method of Momentum approach to unbalanced panel data owing to endogeneity. The findings show that in over-levered firms, the adjustment speed of capital structure is slower with weak corporate governance. This result indicates that managers use debt as a takeover defense tool to protect their jobs, even at the cost of shareholders’ benefits. However, for under-levered firms, the adjustment speed of capital structure with weak governance is slower. This aspect specifies that the disciplinary effect of debt is more important for managers. This study concludes that managers with weak corporate governance take benefits at the cost of shareholders’ wealth. The study recommends that managers should develop an understanding of corporate governance to safeguard the rights of the shareholders.
Quantitative Portfolio Management Through Carbon Budgeting in a PSX Perspective
Authors: Majeed Muhammad Irfan , Arif Unbreen
Published: May 2023

Portfolio management requires investment managers to consider investor preferences before taking any investment decisions. Some of the investors might be interested in building a clean, environmentally friendly, and carbon-free portfolio, assuming it as their corporate social responsibility (CSR) or owing to some fear of future loss arising from the ban on environment-hampering companies that might not be following the environmental, social, and governance (ESG) requirements. Historically, we have seen a ban on Chinese products because of the issues of carbon emissions. Similarly, during SMOG, many brick kilns and iron foundries are closed in Pakistan every year. The carbon budgeting on the portfolio can help achieve the CSR and sustainability goals of investors. The study attempts to develop a portfolio based on historical data, which could yield optimum results while remaining carbon conscious. The study aims to find the best-performing portfolio that could be more ESG compliant and may achieve CSR objectives to protect the environment and investors’ interests simultaneously. The findings show that companies segregated based on carbon footprint can create a carbon-free portfolio (approximately 25%) without a material impact on the expected risk and return profile. To be more ESG compliant, an investor can compromise slightly on returns, that is, only compromising 3% of the profit, we can maintain a 50% compliant portfolio in Pakistan’s environment. The study tries to improve the understanding of regulatory requirements but would also help us gain the confidence of investors who are keen to see carbon-free portfolios or in other words want to ensure investments in environmentally friendly industries.

Research This aims to develop practicum module for making soap with natural active ingredients to improve students' creative thinking skills. Practicum instructions will be applied to natural science and natural product chemistry practicum courses to provide innovations and appropriate technology for science education master students. The development of practicum instructions is a Research and Development (R & D) development with a define, design, develop, and disseminate (4D) model. The samples of this research were chemistry students and Master of Science Education students. The tests carried out were tests of physical properties (organoleptic, pH, and homogeneity) and antimicrobial tests with varying concentrations of trimyristin. Products in the form of practicum module are validated. The results showed that the validity value of the three validators obtained using the Aiken index was V = 0.84, which indicated that the natural science practicum module: the procedure for making trimyristin soap from nutmeg, was very valid and feasible to use. Meanwhile, practicality can be seen from the responses of students and lecturers, who show a positive response with average practicality of all components of 88% of student responses and 89% of lecturer responses. The results of the physical evaluation of trimyristin solid soap (organoleptic, pH, foam stability, and moisture content) produced from this study showed good results because they met several standards for the quality of solid soap SNI 3532-2016. Based on these data, the materials chemistry practicum module: procedures for making trimyristin soap from nutmeg seeds to support meaningful learning that is developed is very valid and very practical to use in the learning process
Nitrate content in roots of pepper seedlings exposed to Phytophthora capsici
Authors: KOÇ Esra , KARAYİĞİT Belgizar
Published: May 2023

Phytophthora capsici causes root rot, a deadly plant disease. Resistance to diseases is produced by the activation of many defense substances, so knowledge of this natural defense mechanism allows the development of new strategies for disease control. In this study, the response of nitrate (NO3-), which is effective in plant growth and development, in different pepper genotypes exposed to pathogen infection was investigated. For this, resistant and sensitive pepper genotypes were exposed to 102, 103, and 104 zoospore/mL of P. capsici-22 strain and changes in NO3- content were determined from root samples taken on the 2nd, 4th and 6th days after infection. All zoospore concentrations resulted in an overall increase in NO3- content in roots of CM-334 on all days. In KM-181 and SD-8 genotypes, the highest NO3- content was determined on the 6th day of 103 zoospore/mL application. In SD-8 and KM-181 genotypes, a significant decrease in the amount of NO3- was determined on the 4th and 6th days of treatment of 104 zoospore/mL. In these genotypes, a decrease in the amount of NO3- was found with the increase in infection time at high zoospore concentration. When the three pepper genotypes were compared, the highest NO3- content was determined in the resistant CM-334 genotype, which was exposed to 104 zoospore/mL on the 6th day following the infection. In this study, changes in the amount of NO3- in resistant and susceptible pepper genotypes indicated that NO3- may be effective in plant defense against P. capsici-22.

В статті проведений аналіз сфер групового застосування безпілотних літальних апаратів (БПЛА). Визначено, що групове використання БПЛА може бути застосовано для оптимізації вирішення завдання за критеріями мінімуму часу та максимуму вірогідності успішності його виконання. Обґрунтовано, що у військово-прикладній сфері виникає необхідність застосування БПЛА у зімкнутих бойових порядках (необхідність прольоту заданої точки простору за мінімальний час, наявність вузьких коридорів для прольоту групою БПЛА тощо), коли відстань між учасниками групи вимірюється в одиницях метрів. У статті проаналізовано існуючі методи оцінки ймовірності зіткнення БПЛА. Запропоновано метод визначення мінімальної відстані між БПЛА у групі при забезпеченні заданого рівня безпеки за рахунок оцінки ймовірності конфлікту при різних значеннях відстані між БПЛА. Наведено модель навігаційної системи (НС) БПЛА, що складається з інерційної НС та системи глобального позиціювання (GPS), а також визначено середньоквадратичні відхилення (СКВ) результату вимірювання положення БПЛА у просторі. В ході проведення розрахунків визначено, що мінімальна відстань між БПЛА типу PD-1 дорівнює 84,6 м, в той час як при використанні методу міжоб’єктової навігації, що полягає у визначенні відстані між БПЛА за рахунок вимірювання часу проходження сигналу між БПЛА та відносного положення шляхом визначення азимуту та кута схилення за рахунок фазового пеленгування мінімальна відстань дорівнює 3,33 м. Наведена модель не враховує час реакції, що необхідний автопілоту для усунення ситуації небезпечного зближення, можливість потрапляння БПЛА в супутній слід іншого учасника групи, що призведе до зниження керованості, проте може бути застосована для оцінки нижньої границі мінімальної відстані між БПЛА у групі.
Das Be_Hindernde ist politisch
Authors: Wallner Laura
Published: May 2023

Der Beitrag arbeitet mit Bezug auf das bekannte Adorno Zitat »Die Forderung, dass Auschwitz nicht noch einmal sei, ist die allererste an Erziehung« die Relevanz der Auseinandersetzung mit dem Konzept der Inklusiven Bildung im Verständnis einer »Bildung für alle« im Kontext gegenwärtiger globaler Krisen heraus. Dabei rückt insbesondere die politische Dimension der Kategorie Be_Hinderung in den Vordergrund, wenn im Sinne Klafkis Bildungsfragen als Gesellschaftsfragen behandelt werden. Nach einer menschenrechtlichen Herleitung des Begriffs der Inklusiven Bildung werden mit Bezug zu den Konzepten Intersektionalität und Othering die Operationalisierbarkeit von »alle« als Adressat*innen Inklusiver Bildung diskutiert und dem entgegenstehende Ausgrenzungsprozesse und ihre Wirkungsweisen im Bildungssystem in den Blick genommen. Pädagogisches Denken und Handeln findet diesem Verständnis nach dann stets in widersprüchlichen Verhältnissen statt, in denen jedoch subjektive Möglichkeitsräume (vgl. Riegel, 2016) ent-deckt und genutzt werden können.
Alevitisch-sunnitische Konflikte in postmigrantischen Einwanderungsgesellschaften
Authors: Tepeli Dilek
Published: May 2023

Ausgeübte und erlittene Gewalt zwischen Kollektiven verschwindet nicht einfach. Ihre psychosozialen Folgen wirken oft über Generationen hinweg fort. Sie werden bewusst und unbewusst tradiert, nonund para-verbal, interaktiv sowie sprachlich. Dies gilt für physische, psychische und symbolische Verletzungen, wie sie in stigmatisierenden Bezeichnungen, Etiketten der Gruppenschande und fantasiegeleiteten Erzählungen über ganze Kollektive zum Ausdruck kommen. Psychosoziale Spätfolgen vergangener, traumatisierender Gewaltbeziehungen zwischen Kollektiven äußern sich in bestehenden, dynamisch verlaufenden Gruppenabgrenzungen und in sozio-emotionalen Bindungsblockaden, die in vorurteilsund affektgeladenen Wissensbeständen über das Eigene und das Andere zum Ausdruck kommen. Am Fallbeispiel der fortwährenden alevitisch-sunnitischen Verletzungsverhältnisse in der postmigrantischen Gesellschaft illustriert dieser Beitrag – exemplarisch am Beziehungsmodus der alevitisch-sunnitischen Ehe – fortwirkende Folgen intergenerational übertragener, potenziell traumatisierender Gewalterfahrungen.
