Der DAS-Basisdienst "Klima und Wasser". Zentrale Informationsgrundlagen für die Anpassungspraxis in Deutschland - Ein Erfahrungsbericht nach drei Jahren Laufzeit
Authors: Nilson Enno ,   DAS-Basisdienst "Klima und Wasser"
Published: January 2024

Die Anpassung an den Klimawandel gewinnt auch in Deutschland zunehmend an Bedeutung. Die 2008 durch den Bundestag verabschiedete "Deutsche Anpassungsstrategie an den Klimawandel" ("DAS1.0") setzt auf Bundesebene einen Rahmen für die Erfassung des bereits erfolgten und für die Zukunft projizierten Klimawandels und gibt einen Überblick über Anpassungsmaßnahmen in verschiedenen Handlungsfeldern. Eine "DAS2.0" zielt - basierend auf einem neuen Klimaanpassungsgesetz - auf die Konkretisierung von Anpassungskonzepten, das "Messen" sowie die Zielerreichung der Anpassungsbemühungen.
In diesem Kontext sind konsolidierte Daten zum Klimawandel und seinen Folgen, leicht zugängliche Nutzerschnittstellen und eine zielgruppengerechte Beratung eine wesentliche Voraussetzung für ein einheitliches und transparentes Vorgehen. Diese Aufgaben übernimmt der DAS-Basisdienst für die zentralen Themengebiete "Klima" und "Wasser". In diesem Dienst stellen DWD, BfG, BSH und BAW seit 2020 (Pilotphase "PROWAS" seit 2016) dauerhaft und regelmäßig entsprechende Leistungen bereit. Zentrale Themen sind unter anderem der Einfluss des Wandels meteorologischer Größen auf den Wasserhaushalt, das Abflussgeschehen und den ökologischen Zustand der größeren Flüsse Deutschlands sowie der Einfluss des globalen Meeresspiegelanstiegs auf die deutschen Küsten und Ästuare.
Nach drei Jahren liegen neben zahlreichen Datenprodukten, die unter anderem in die "Klimawirkungs- und Risikoanalyse" des Bundes (KWRA2021) eingeflossen sind, umfangreiche Erfahrungen zu den Möglichkeiten und Herausforderungen der Überführung von Klimawissen in die Anpassungspraxis vor. Der Beitrag gibt einen Einblick in das Produktportfolio des DAS-Basisdienstes. Er nennt Beispiele einer erfolgreichen (d.h. konkreten und einfachen) Einbeziehung von Klimawissen in die Geschäftsprozesse von Institutionen, die für die Umsetzung von Anpassungsmaßnahmen verantwortlich sind. Er gibt einen Überblick über etablierte Strukturen der Zusammenarbeit, die für die Abstimmung von Vorgehensweisen, Datengrundlagen und letztlich Anpassungsfortschritte unverzichtbar sind.

Predicting climate impacts for the cause of anticipatory action - climate services for the disaster relief and humanitarian aid sector
Authors: Geiger Tobias , Potzauf Merle , Detring Igor , Castino Fabiana , Krüger Moritz , Kreienkamp Frank
Published: January 2024

The variability of meteorological extreme events in Europe is strongly affected by climate change. As a result, the frequency, duration and intensity as well as the place of occurrence of extremes is changing alongside the socio-economic impacts for European communities. As climate change continues, climate forecasts represent a valuable tool for predicting upcoming high-risk climate conditions in advance to support decision-makers in the implementation of preventive and preparatory measures, also known as anticipatory action. Anticipatory action links weather and climate predictions with risk information to initiate early actions to mitigate potential disaster impacts before a shock occurs and to strengthen long-term emergency preparedness. 
Here, we present an anticipatory action project jointly conducted by Deutscher Wetterdienst (DWD) and Deutsches Rotes Kreuz (German Red Cross). The project aims at co-developing DWD’s German Climate Forecast System (GCFS) towards climate impact forecasting, initially for heat-related impacts but also for various other hazards, e.g., cold, wind or precipitation. These impact forecast products are intended to help the authorities as well as relief organizations such as the Red Cross to pre-define measures that can mitigate anticipated impacts, e.g., on particularly vulnerable people. 
As a first step, the GCFS is currently extended to include the forecast of selected temperature extreme indices, including the number of hot days and warm spells, which are key for the evaluation of health and mortality risks. In subsequent steps, the forecast products are jointly evaluated and refined in collaboration with the specific user community (e.g. informing communities and disaster authorities about potential health impacts in care facilities, hospitals, or on rescue and relief personnel) within a co-design process. In our poster we will detail how our transdisciplinary procedure contributes to increasing the performance and usefulness of climate forecasts in order to effectively support decision-makers, emergency and health workers about the expected impacts to mitigate impacts and protect vulnerable groups.
Was sind die Ursachen der exorbitanten Rekorde der globalen Temperaturmittel von bodennaher Atmosphäre und Meeresoberfläche im Rekordjahr 2023?
Authors: Becker Andreas , Friedrich Karsten , Niermann Deborah , Imbery Florian
Published: January 2024

Bereits im Jahr 2022 lag das globale Mittel der Temperatur 1,15 Kelvin über dem vorindustriellen Niveau (1850-1900) und damit nur noch 0,35 K unter der 1,5-Grad-Schwelle des Pariser Klimaabkommens. Schon ohne das Rekordjahr 2023 waren die vergangenen acht Jahre global die wärmsten seit Beginn der Aufzeichnungen und das, obwohl die Jahre 2020-2022 ausgeprägte La Niña Jahre waren, von denen wir wissen, dass sie eher kühlend auf das globale Mittel wirken.
Im Laufe des Jahres 2023 endete aber die La Niña Phase und wurde von einem zumindest mäßig ausgeprägtem El Niño Ereignis abgelöst. Gleichzeitig hat es exorbitante positive Abweichungen der globalen Mittel der Temperaturen der bodennahen Atmosphäre und der Meeresoberflächen gegeben, die so weit über allen bisherigen Aufzeichnungen liegen, dass eine vollständige Attribution zum anthropogenen Klimawandel, selbst zuzüglich des vorübergehenden Zusatzeffektes durch das vorbenannte El Niño Ereignis, nicht schlüssig ist. So liegt das globale Oktobermittel 2023 bereits über der 1,5 Grad Schwelle des Pariser Klimaabkommens und Mitte November übertrafen (mindestens) zwei Tagesmittel sogar die 2,0 Grad Schwelle. Das Jahr 2023 wird somit global mit weitem Abstand alle vorherigen Rekordjahre übertreffen und es müssen entweder weitere Einflussfaktoren eine Rolle gespielt oder die globale Erwärmung sich massiv beschleunigt haben. Im Einklang mit der Thematik der Session 1 sollen daher die natürlichen und anthropogenen Einflussfaktoren auf diese Rekorderwärmung besprochen werden. Dazu gehören auch Ursache und Einfluss der marinen Hitzewellen und der Erhöhung des stratosphärischen Wasserdampfeintrages im Nachgang der Unterwassereruption des Hunga Tonga im Pazifik.
Was bedeutet dies für das globale Jahresmittel in den nächsten beiden Jahren und darüber hinaus? Wie stark reduziert sich der Abstand zur vorbenannten ambitionierten Schwelle schon in den nächsten beiden Jahren, oder überschreiten wir diese gar nachhaltig? Was sind die charakteristischen Zeitskalen einer Überschreitung und wie vermeiden wir eine erneute „Hiatus“ Diskussion wie im Nachgang des El Niño 1998? 
Sommertrockenheit in Nordostdeutschland im europäischen historischen Kontext–Einblicke durch stabile Isotope in Baumjahrringen.
Authors: Helle Gerhard , Freund Mandy , Nagavciuc Viorica , Heinrich Ingo , Balanzategui Daniel
Published: January 2024

Bäume sind weit verbreitete Archive für Umwelt- und Klimaveränderungen. Zeitreihen von Klimaparametern, die aus Baumjahresringen abgeleitet werden, bieten einen historischen Rahmen für die jüngsten Klimaerwärmungstrends und Extrema. Isotopenverhältnisse von Kohlenstoff (13C/12C) und Sauerstoff (18O/16O) in Baumringen bieten eine hervorragende Möglichkeit, die Trockenheit vergangener Sommer in verschiedenen Ökosystemen und über Klimazonen hinweg zu untersuchen. Aktuelle räumliche Rekonstruktionen hydroklimatischer Bedingungen in Europa unter Verwendung eines Netzwerks von Messungen stabiler Jahrring-Isotope haben für die letzten 400 Jahre eindeutig demonstrieren können, wie außergewöhnlich die Sommerdürren seit 2015 waren. Als besonders betroffene Regionen wurden West- und Mitteleuropa identifiziert. Anlehnend an diese Studien sollen hier neue Jahrringisotopendaten aus Nordostdeutschland präsentiert werden, um das europäische Netzwerk der stabilen Isotopendaten zu stärken und unser Verständnis der lokalen und regionalen Ausprägungen der globalen Klimaerwärmung zu vertiefen. Bei der Analyse der Jahrring-Isotopenzeitreihen fallen abgeschwächte Klimasignale in den Jahren 1960 bis 1990 für bestimmte Standorte Nordostdeutschlands auf, die wir den damaligen unkontrollierten Emissionen von sauren Luftschadstoffen zuschreiben. Darüber hinaus sollen Hinweise auf einen stärkeren Wasserbedarf durch erhöhte Transpiration an einigen Baumstandorten diskutiert werden, welcher nicht nur auf die jüngsten Dürren zurückzuführen ist, sondern auch Folge langfristiger Auswirkungen früherer Umweltverschmutzung zu sein scheint.
Wälder-Wolken-Wechselwirkungen.
Authors: Quaas Johannes , Kretzschmar Jan , Luo Hao
Published: January 2024

Wälder wechselwirken mit Wolken, indem sie die Flüsse von Partikeln, Wasser und Energie in die Atmosphäre beeinflussen. Umgekehrt regulieren Wolken die Strahlungs- und Niederschlagsflüsse von oben. Im Vortrag werden zwei Mechanismen diskutiert. Verschiedene Baumarten emittieren zu unterschiedlichen Jahreszeiten Pollen. Anhand von Satellitenbeobachtungen von Wolken und Niederschlag, in Kombination mit Pollenfallennetzwerkbeobachtungen über den USA zeigen wir, dass Wolken vermehrt aus Eis statt aus Flüssigwasser bestehen, wenn mehr Pollen in der Atmosphäre sind. Dies bedeutet u.a. eine höhere Niederschlagshäufigkeit über Wäldern. Zweitens schauen wir Klimamodellsimulationen an, die die Effekte von Entwaldung untersuchen. Hier finden wir für die Abholzung von borealen Wäldern eine Reduktion des Bedeckungsgrads mit tiefen Wolken. Dies bedeutet, dass Entwaldung - anders, als man anhand der Albedoerhöhung annehmen würde - einen erwärmenden Einfluss auf das Klima hat.
Impact of Asian aerosols on the summer monsoon strongly modulated by regional precipitation biases
Authors: Liu Zhen , Bollasina Massimo , Wilcox Laura
Published: January 2024

Abstract. Reliable attribution of Asian summer monsoon variations to aerosol forcing is critical to reducing uncertainties in future projections of regional water availability, which is of utmost importance for risk management and adaptation planning in this densely populated region. Yet, simulating the monsoon remains a challenge for climate models which suffer from long-standing biases, undermining their reliability in attributing anthropogenically-forced changes. We analyse a suite of climate model experiments to identify a link between model biases and monsoon responses to Asian aerosols, and the physical mechanism underpinning this link, including the role of large-scale circulation changes. The aerosol impact on monsoon precipitation and circulation is strongly influenced by a model’s ability to simulate the spatial distribution and temporal variability of the climatological monsoon winds, clouds and precipitation across Asia, which critically modulates the magnitude and efficacy of aerosol-cloud-precipitation interactions, the predominant driver of the total aerosol response. There is a strong interplay between South and East Asia monsoon precipitation biases and their relative predominance in driving the overall monsoon response. We found a striking contrast between the early and late summer aerosol-driven changes ascribable to opposite signs and seasonal evolution of the biases in the two regions. A realistic simulation of the evolution of the large-scale atmospheric circulation is crucial to realise the full extent of the aerosol impact over Asia. These findings provide important implications to better understand and constrain the diversity and inconsistencies of model responses to aerosol changes over Asia in historical simulations and future projections.
Stand on Dialogic Pedagogy in Our Times of Peace and War: My Perspective on December 12, 2022
Authors: Matusov Eugene
Published: January 2024

This essay represents the publication of my keynote address at the First DPJ online conference on December 12, 2022. In my speech, I defined how I perceive “our times” and how Dialogic Pedagogy in our times of peace and war may try to address these challenges or even if we should do so. I continued developing the concept of Ontological Dialogic Education. What is the role of Ontological Dialogic Education in addressing the challenges of our times, and is it relevant at all? Why and how can it contribute to a vision of a liberal democracy, if at all? This questioning let me introduce a key post-Enlightenment notion of education based on students’ self-determination and dignity.
The impact of libraries and informationists on patient and population care: a mixed-methods study
Authors: Shannon Carol , Freeman Jacqueline , MacEachern Mark , Rana Gurpreet , Smith Craig , Smith Judith , Song Jean
Published: January 2024

Objective: While several studies have examined the effectiveness of librarian interactions with clinicians and impact of librarians on patient care, no studies have explored a library’s effects on population care. The goal of this study was to investigate the library’s impact on both patient and population care.
Methods: Using a sequential exploratory mixed-methods design, we first interviewed a small set of clinicians and researchers active in patient and population care. Based on the themes that we discovered through coding the interviews, we created a survey that was sent to faculty in the health sciences and the health system.
Results: We collected data from a representative sample of our population. We discovered that all respondents value the library and informationists, using our services most for teaching, publishing, presenting, and professional development.
Conclusion: We now have data to support our value to our population and to show where we can do more work to improve the use of our services. Our study shows the value of doing a mixed-methods sequential exploration in which themes that are important to our user community were identified prior to launching a large-scale survey.
Negative influence of a mediatised video on low back pain-related misbeliefs and attitudes in the general population
Authors: Demoulin Christophe , Lecaillon Mathilde , Christe Guillaume , Vanderthommen Marc , Pitance Laurent
Published: January 2024

Background: Low back pain (LBP)-related misbeliefs are a risk factor for chronicity and thereby requires further attention.

Objective: To assess the influence of a video clip on low back pain (LBP)-related misbeliefs in the general population and examine whether participants intended to change their behavior to protect their back after viewing it.

Method: French-speaking adults within the general population were recruited through advertisements and asked to complete a self‐administered questionnaire online from the January to April 2021. The questionnaire asked about socio-demographic information and back pain beliefs (the 10-item Back-PAQ), then invited participants to watch a video clip conveying negative messages. Immediately after viewing, participants indicated their degree of agreement with the messages conveyed, completed the Back-PAQ a second time and indicated whether they planned to change their behavior after watching the video.

Changes in mean Back-PAQ score after viewing the video and the percentage of participants planning to protect their backs more were investigated. Influence of LBP history was also collected.

Results: 1338 participants were included. The initial mean Back-PAQ score was high and increased significantly after viewing the video (Cohen d: 0.42), indicating an increase in negative beliefs. This change was greater than the minimum detectable change for more than 10% of participants. In total, 55% of respondents reported that they would protect their backs more after watching the video. Change in Back-PAQ score post viewing was not influenced by pain history.

Conclusions: This study shows that a video clip shown on social media that conveyed negative messages about LBP reinforced LBP-related misbeliefs and may promote maladaptive behavior in a significant number of individuals. This study also confirms the prevalence of such misbeliefs in the general population and thereby, the necessity for clinicians to explore patients’ misbeliefs and their origin.

Macroeconomic Factors of Stock Market Development (The Case of Saudi Arabia)
Authors:   Assistant professor, Finance Department, Faculty of Economics and Administration, King Abdulaziz University, Jeddah, Saudi Arabia., Alalmai Somaiyah
Published: January 2024

Most economists recognize that a healthy capital market can enhance economic growth. In 2016, Saudi Arabia launched Vision 2030, and the Financial Sector Development Program is part of the Vision. The program aims to achieve economic diversification, reduce oil dependence, and trigger economic growth. Capital market development has an integral part to play in achieving Vision 2030 goals. For this reason, it is essential to investigate the factors that could influence it. The literature on the impact of macroeconomic factors on the stock market development is inconclusive; thus, it is difficult to generalize the outcome of previous studies. This research investigates the macroeconomic and institutional determinants of stock market development in Saudi Arabia from 2008 to 2021 by using a multiple linear regression approach. Following previous research, our analysis explores the impact of several factors, including Global Trade Openness, Market Depth, Macroeconomic Stability, Control of Corruption, Income level, Private capital flows, Financial intermediary development, Economic Development, Domestic Savings and investment. Among the nine evaluated factors, only four were significant. We find that the determinants of stock market development in Saudi Arabia are Economic Development, Income level, Control of corruption, and Market Depth.

Published: January 2024

This study examines the complex relationships between Cash Conversion Cycle and firm profitability using a dataset of seven companies. The primary goal is to assess the subtle impact of the Cash Conversion Cycle (CCC) on two key dependent variables: Return on Assets (ROA) and Earnings Per Share (EPS). The focus of this investigation is on four independent variables: leverage ratio, quick ratio, current ratio, and debt to service ratio. In a departure from conventional wisdom, our findings call into question established financial theories by demonstrating the CCC's insignificant impact on ROA. However, the CCC's critical role in influencing EPS highlights the CCC's diverse implications for financial performance. The alignment of the Leverage Ratio with financial theories has a significant impact on ROA. This research provides nuanced insights into the complex dynamics of financial ratios and their collective impact on firm profitability. The findings provide strategic guidance for financial decision-makers, emphasizing the importance of a customized and sophisticated approach to working capital management in navigating the complexities of today's dynamic business environment, and the study recommended to create CCC strategies that are unique to each company's industry dynamics, Take into account industry benchmarks when optimizing the CCC for improved financial performance.
Fulani Nationalism and the Use of Herdsmen to Forcibly Acquire Land Belonging to Natives in Nigeria
Authors:   Ph.D. International Relations Candidate, Department of Political Science and International Relations, Faculty of Business and Economics, Eastern Mediterranean University, North Cyprus, Turkey, Igwenyere Frederick
Published: January 2024

Fulani people can be found in many African states, especially in West Africa. The Fulani who are mainly nomads and Muslims, migrated to Nigeria in the 13th Century and conquered the Hausa ethnic group in the 18th Century. Thereafter, they established their rule over the Hausa and other ethnic groups in Northern Nigeria through the Sokoto Caliphate. The study analyses how the sedentary Fulani use the nomads, herding cattle across the country to acquire land from the natives through intimidation and violence forcibly. The sedentary Fulani who are often well educated and sophisticated use their positions in government to protect and defend the herdsmen. Many authors have attributed climate change as the main reason causing the conflicts between Fulani herdsmen and farmers in Nigeria. The study does not support this assertion. Rather it finds that the attempts by native farmers to resist land grabbing by the nomads lead to conflicts. The study adopted a qualitative method to review some earlier literature on the phenomenon and proffer solutions to the avoidable and unnecessary clashes that have led to the deaths of many farmers and other natives across the country.

AVALIAÇÃO DO COMPORTAMENTO REOLÓGICO DAS MATRIZES CIMENTÍCIAS COM A ADIÇÃO DE NANOTUBOS DE CARBONO: UMA REVISÃO SISTEMÁTICA DA LITERATURA (RSL) – PARTE 2
Authors: Gomes Martins Bárbara , Oliveira Andrielli Morais de , Cascudo Oswaldo
Published: January 2024

RESUMO: Os nano-materiais têm sido cada vez mais empregados nos compósitos cimentícios, visto que estes são tipicamente caracterizados como materiais frágeis com baixa resistência à tração e baixa capacidade de deformação. Dentro da categoria de nano-materiais encontram-se os nanotubos de carbono (NTCs). Este trabalho faz uma continuação da Parte 1, trazendo os resultados bibliométricos dessa RSL e as contribuições adquiridas para o estado da arte dos parâmetros reológicos das matrizes cimentícias reforçadas com NTCs. Diante dos resultados é possível concluir que a string de busca foi eficaz para encontrar pesquisas que estudam reologia de matrizes cimentícias incorporadas com NTCs. Contudo, a correlação dos artigos visando isolar o efeito dos NTCs se torna inviável diante da vasta disponibilidade de variações nas composições das matrizes cimentícias. De uma forma geral, foi verificada uma maior tendência no aumento da viscosidade ao introduzir NTCs nas matrizes, o que geralmente é atribuído à grande superfície específica dos NTCs. Diante da natureza hidrofóbica do NTCs, existe uma variedade de: matrizes cimentícias; características do NTC; funcionalização da superfície; aditivo utilizado no processo; método para dispersão adotado e suas características; teor de NTC incorporado em relação à massa de cimento; relação a/c; entre outros. Portanto, mais pesquisas devem ser desenvolvidas de forma a correlacionar as variáveis que circundam os NTCs para potencializar seu uso nos compósitos cimentícios.
Analysis of the Prospects for Overcrowded Classes in Elementary and Secondary Schools According to Future Population Changes
Authors:   Korea Society Of The Politics Of Education, Yoon Ki Hyun
Published: January 2024

As the classroom is not only a spatial concept in which learning activities are carried out together by teachers and students, but also a basic condition for professional educational activities of teachers, it is important to analyze overcrowded classes and establish policy directions for them. Accordingly, this study examined the changes in the school-age population and the current status of overcrowded classes in elementary and secondary schools, and projected the future overcrowded classes for elementary and secondary schools, and presented policy directions and implications related to overcrowded classes in the future. To this end, the school-age population provided by the National Statistics Office and the Ministry of Public Administration and Security was analyzed using the cohort factor method using basic data, and compared with the actual population changes in the area for major school districts where overcrowded classes occurred. As a result of the analysis, the number of students and the number of future classes is expected to gradually decrease due to the decrease in the school-age population, and the overcrowded class will continue to decline until 2036 except for 2025 according to this trend, and it will rebound from 2037 but decline again, and the overcrowded class in 2040 is expected to decrease by 65.2% compared to 2023. Based on these results, we proposed future policy recommendations related to overcrowded classrooms.
The ‘Educational’ Effects of Parent-Inclusive School Culture: Focusing on Economically and Culturally Disadvantaged Students
Authors:   Korea Society Of The Politics Of Education, Cho Yejin , Song Hyojune
Published: January 2024

This study emphasizes the role of parental involvement as a valuable school-level resource rather than just a private matter. As previous studies have explored the benefits of parental involvement, this study focuses on a broader view of parental involvement in school education as a shared educational asset for all students. Specifically, this research explores the positive impacts of cultivating a parent-inclusive school culture, with a particular focus on students facing economic and cultural disadvantages. Using South Korean subset of PISA 2018 dataset, this study conducted multi-level logistic regression analysis for 839 students from 169 schools. As a result of the study, this study suggests that actively promoting and supporting parental involvement at school level can help alleviate some of the educational challenges faced by these disadvantaged students. In the context of South Korea, where addressing the educational disparities related to families' economic and cultural backgrounds is a significant societal concern, this study offers valuable insights for future educational reforms.
“The power of collaboration is remarkably potent!”: A Qualitative Case Study on the Formation of Collaborative Relational Structure of a Global Citizenship Education Research Team at Moonlight Primary School
Authors:   Korea Society Of The Politics Of Education, Lee Sung Hoe
Published: January 2024

This qualitative case study explored the collaborative relational structure of a research team of educators at Moonlight primary school (pseudonym), which enabled the mainstreaming of global citizenship education(hereafter, GCED) into the school over the past three years. To do so, this research employed the relational AGIL scheme(Donati, 2022) as a theoretical framework to analyze changes in the purpose, values, means, and norms of the research team’s relational structure. The findings revealed that the research team underwent transition from an initially contrived collegiality to a later reciprocal one, with the turning point marked by a change in leadership. The late-stage research team’s reciprocal relational structure was characterized by a pursuit of situational goals (G) related to the mainstreaming of GCED at Moonlight primary school, grounded in values of mutual respect(L), a sophisticated planning of various means(A) meticulously designed for mainstreaming GCED, and an emphasis on ethical responsibilities within teacher relationships(I), forming an AGIL relational structure. The key mechanism in shaping this reciprocal relational structure(AGIL) was the relational reflexivity of the research team members. They, as relational subjects, were able to recognise the relational order of reality, that is, we-‘relation’, a third entity constructed by team members that remains invisible but embodies the potential for teacher collaboration.
Analysis of University of Seoul’s Tuition Fee Policy Changes Using the Modified Multiple Streams Framework and Advocacy Coalition Framework
Authors:   Korea Society Of The Politics Of Education, Kim Kyuseok , Jo Seongbin , Kim Soohyuk , Lim Karam
Published: January 2024

In this study, we employ an analytical framework that combines the modified multiple streams model, based on Kingdon’s original multiple streams framework with the advocacy coalition framework to investigate the agenda-setting and decision-making process of University of Seoul’s half-price tuition policy. We describe characteristics found within the debates concerning the abolition of this half-price tuition at the case institution. Central to our argument is the theoretical and conceptual validity of the modified multiple streams model when applied to real-world policy phenomena. In addition, we elucidate the changing patterns and reasons for change in advocacy coalition activities based on political streams. This study’s model proves beneficial for analyzing South Korea’s educational policy, especially as the modified multiple streams framework introduces a concept of political entrepreneurs that prior research did not highlight. We argue the need for a critical reflection on the traditional multiple stream framework’s concept of policy entrepreneurs in addition to that the explanatory power of the advocacy coalition model may diminish in contexts where political streams exert stronger influence than policy streams. Furthermore, it is essential to contextualize foreign-developed policy analysis models to fit South Korean circumstances and to adopt and utilize the concept of ‘entrepreneurship’ in a flexible and dynamic manner.
Analyzing the Discourse of the High School Credit System Through the Policy Argument Model
Authors:   Korea Society Of The Politics Of Education, park kyunyeal
Published: January 2024

This study analyzes the discourse through the policy argument model and proposes implications for policy implementation under the recognition that the policy means and contents are important for the correct implementation of the policy purpose of the high school credit system. To achieve the research purpose, this study reorganized and utilized Toulmin et al.’s (1979) analysis framework.The conclusions of the analysis using the policy argument model are as follows. First of all, since the high school credit system is an education policy that requires public consensus in consideration of its linkage with university entrance examinations, it is necessary to solidify the foundation for a soft landing sequentially through the process of social consensus and public discussion. Next, we need to move away from the tendency to take a piecemeal approach to the issues of the high school credit system’s curriculum, teaching and learning, educational evaluation, and teachers and facilities, and move toward the holistic approach. There needs to be a soft landing for unit schools with an organic approach. As suggested in the argumentative analysis of this study, it seems necessary to have a strategy that can comprehensively enhance the technical feasibility and political feasibility.
Estimation of Higher Education Institution Expenditure by Cost-Function: Focus on 4-year Domestic Universities
Authors:   Korea Society Of The Politics Of Education, Hwang Youngsik , Joo YoungHyeo
Published: January 2024

The purpose of this study was to estimate the expenditure of universities by using cost function. For the research purpose, this study used indicators related to major education and research functions of 125 universities in Korea in the 2022 disclosure data of Academy Information System. The analysis results are as follows. First, the number of enrolled students had an effect on the expenditure of the university and that there was an economy of scale for the estimated cost according to the increase in the number of enrolled students. However, the economy of scope did not appear meaningful. In addition, the number of students per full-time faculty, the annual salary of full-time faculty, the rate of securing full-time faculty, and the education expenditure per student also showed significant influence. It can be seen that these results show differences in the influence depending on whether the interaction between variables is considered and the nature of the dependent variable. Second, the marginal cost per student of private universities in the metropolitan area were relatively high. Finally, there are some differences between actual and estimated expenditures in the institutions. The difference may exist depending on the characteristics of various universities. Based on the above research results, this study discussed policy and academic implications related to cost estimation for higher education institutions.

This paper purposed to analyze the marketization of education according to education policy determined by political factors by presenting changes in private education investment and private school enrollment rates in European and North American countries according to government partisanship. As with other policies, it was derived that fundamental changes occur in educational policies because of political factors rather than fragmentary educational considerations.
Based on the main support of the high-income class, the right-wing party revitalizes the education market. It lowers education regulations to increase the effectiveness of private investment in education. As a result, there is a high possibility that education marketization will intensify. On the contrary, the left-wing party supported by the low-income class tries to reduce the effect of private investment. Rather than segmentation according to the special separation of secondary education, integration and education regulation are strengthened to reorganize the system to lower the marketization of education.
This article, I looked at education marketization according to government partisanship and analyzed changes in education policy. Regarding education marketization, the ratio of private education expenditure and the ratio of private school student enrollment were used as dependent variables, and the cabinet composition ratio of left-wing and right-wing parties was used as independent variables. Through panel statistical analysis, this article obtained significant results on the changes in education marketization that differ depending on the left and right-wing government partisanship.
In conclusion, it can be seen that the partisanship of the governments of the left and right has changed the education policies to realize the policies of their constituencies.

In the middle part of Central Kazakhstan there are linear copper-bearing riftogenic-orogenic zones of sublatitudinal strike (Spassk and Uspensk zones) with numerous sulfide and porphyritic deeply eroded deposits and ore occurrences of copper not currently presenting commercial interest due to insignificant reserves and Zhezkazgan basin conjugated with them in which first-rate deposits of cupriferous sandstones are located. Formation of sulfide deposits occurred in the process of riftogenesis, and porphyritic deposits were formed in orogeny. Copper was carried away by river waters together with broken rocks, minerals and organic matters from the mentioned zones with humid climate into arid littoral-deltoid areas of the Zhezkazgan sea basin in the Carboniferous-Permian, where water soluble copper compounds sedimented under the influence of hydrogen sulphide of biogenic sulfate-reduction. Gradual upthrusting of the north side of the basin shifted the riverbed in the undercurrent many times. This resulted in forming of deposits of different ages: from the Middle (The North group) and Middle-Upper Carboniferous (Zhezkazgan) to the Upper Permian (Taskora). It is possible that between the latter ones there are some large deposits localized in lenses of alluvial deposits controlled by paleofaults situated in multiple distances. To discover them a complex of geological and geophysical prospecting methods is proposed.

A mathematical model of coal’s self-heating in the stack is presented, where the heat exchange and gas exchange processes are described by a system of two non-linear differential equations of the second order concerning temperature t of coal’s self-heating and volume fraction C of oxygen in the cavities of the stack with boundary and initial conditions. The differential equations took into account that self-heating of coal in the stack and initiation of self-ignition are observed in a relatively small layer adjacent to the surface of the stack and called the zone of oxygen influence. In this mathematical model authors have taken into account the influence on the process of coal’s self-heating of parameter Ф – specific heat release power, which in addition characterises the preservation of coal during storage. There were also used such physical parameters as thermal conductivity, diffusion coefficient, specific heat capacity of coal in the stack, bulk density, thermal effect of oxidation, stack cavity, temperature coefficient of exponential growth of heat release power when compiling the differential equations. For numerical implementation of this mathematical model, there were introduced dimensionless variables and criteria, which allowed to apply the grid method. Analysis of the final results allowed to obtain: changes in stack temperature profiles in time; changes in stack oxygen concentration profiles in time; influence on stack temperature profile of specific heat release power; influence on stack temperature profile of the parameter characterising exponential growth of heat release intensity with increasing temperature. It has been found that the greatest influence on the dynamics of self-heating of coal in the stack has the Lykov criterion, proportional to the diffusion coefficient, and the Nusselt criterion related to the effective thermal conductivity and the effective thermal diffusivity of coal. The results obtained suggest that self-heating in the stack is due, on the one hand, to intensive penetration of air oxygen and, on the other hand, to impaired heat dissipation. Self-heating and the transition of self-heating into ignition is associated with the occurrence of turbulent diffusion in the stack, arising from increased heat blowing, the effect of which can be enhanced when directed perpendicular to the surface of the stack.

Kokshetau ore district is a large rare-metal ore province with a tungsten-tin mineralization profile, including such deposits as Sarymbet, Sarybulak, Donetsk, Usken and a number of other small objects. The most studied deposit of the district is Sarymbet, the rest are poorly studied and require further study. The tin ore objects of the district are associated with the granites of the Orlinogorsk intrusive complex and are confined to the supra-intrusive zones. Mineralization is localized in the modified rocks of the Sharyk formation. The Kokshetau ore district has sufficient prospects for the discovery of new objects.

The article is devoted to the study of the optimal parameters of the cleaning chambers and targets during the processing of low-power ore bodies by the system of a sub-storey collapse. A detailed analysis of existing methods for calculating the permissible parameters of cleaning chambers and tselikov was carried out. On the basis of an analytical comparison, the effectiveness of leaving inter-chamber and inter-floor targets in the fight against over-planned dilution during mining of ore bodies with a low power of no more than 2.5-3.0 meters is estimated. Special attention was paid by the authors to the results of foreign researchers. As a result of the research, a stability graph was constructed to determine the permissible parameters of the cleaning chambers depending on the geological strength index. The purpose of the article is to substantiate the optimal parameters of purification chambers and tselikov in order to reduce the dilution of ore during the development of low-power ore deposits.Methodology. The analysis of existing methods and design solutions used to substantiate the optimal parameters of cleaning chambers and tselikov is carried out. Geomechanical studies of the rock mass have been carried out using recognized methods of the International Society for Rock Mechanics (International Society for Rock Mechanics). By mapping the walls of the workings, the geological index of the GSI array is determined. Based on the Mathews graphical stability method based on the rock classification system, the hydraulic radius was measured, characterizing the ability of the rock mass to remain stable under given conditions of stress, structural organization of violations of the massif and orientation of the cleaning space. Numerical analysis of the rock mass by finite element methods is performed. On the basis of the performed studies, a dependence graph is constructed that allows determining the permissible parameters of the chamber depending on the geological strength index.
