Ohjaamon jälkeen ‒ tutkimus Ohjaamon asiakkaina olleiden nuorten siirtymistä ja toimeentulotuen saannista
Authors: Vauhkonen Teemu , Latvala Antti
Published: June 2023

Tutkimuksessamme tarkastelimme rekisteriaineiston avulla Ohjaamo­asioinnin yhteyttä nuorten työssäoloon, opiskeluun, palkkatuettuun työhön osallistumiseen sekä toimeentulotuen asiakkuuteen 0–3 vuoden aikavälillä. Vertasimme OhjaamossaTE-­asiakkaina asioineita nuoria tavanomaisessa TE­-palveluprosessissa asioineisiin nuoriin. Tutkimusaineistona käytimme hallinnollisista rekistereistä koottua pitkittäisaineistoa (n =14 141) ja menetelmänä lineaarista todennäköisyysmallinnusta. Verrokkiryhmä muodostettiin niistä nuorista, joiden asuinkunnassa ei ollut Ohjaamoa. Ohjaamoissa TE­asiakkaina olleet nuoret päätyivät seurantajakson ensimmäisten vuosien aikana opiskelemaan ja palkkatuettuun työhön todennäköisemmin kuin tavanomaisessaTE-­palveluprosessissa olleet nuoret. Seuranta-­ajan lopulla ryhmien välillä ei kuitenkaan enää ollut eroa opiskelun todennäköisyydessä. Avoimilla työmarkkinoilla työskentely oli Ohjaamossa asiakkaina olleilla nuorilla epätodennäköisempää kuin vertailuryhmän nuorilla seuranta­-ajan alkupuolella, mutta seuranta­-ajan lopulla ryhmien välillä ei enää ollut eroa avoimilla työmarkkinoilla työssä olon todennäköisyydessä. Sen lisäksi, että Ohjaamossa asiakkaina asioineet nuoret päätyivät seuranta-­aikana todennäköisemmin opiskelemaan kuin tavanomai­sessa TE-­palveluprosessissa olleet nuoret, heillä oli pienempi todennäköisyys jäädä toimeentulotuen asiakkaaksi seuranta-­ajan loppuun mennessä. Tämä viittaa siihen, että tavanomaisessa palveluprosessissa TE-­asiakkaina olevat nuoret putoavat ja jäävät todennäköisemmin toimeentulotuen varaan kuin Ohjaamossa, jossa nuorille tarjotaan laaja­-alaista moniammatillista tukea.
Paradoxical evidence weighting in confidence judgments for detection and discrimination
Authors: Mazor Matan , Maimon-Mor Roni O. , Charles Lucie , Fleming Stephen M.
Published: June 2023

When making discrimination decisions between two stimulus categories, subjective confidence judgments are more positively affected by evidence in support of a decision than negatively affected by evidence against it. Recent theoretical proposals suggest that this “positive evidence bias” may be due to observers adopting a detection-like strategy when rating their confidence—one that has functional benefits for metacognition in real-world settings where detectability and discriminability often go hand in hand. However, it is unknown whether, or how, this evidence-weighting asymmetry affects detection decisions about the presence or absence of a stimulus. In four experiments, we first successfully replicate a positive evidence bias in discrimination confidence. We then show that detection decisions and confidence ratings paradoxically suffer from an opposite “negative evidence bias” to negatively weigh evidence even when it is optimal to assign it a positive weight. We show that the two effects are uncorrelated and discuss our findings in relation to models that account for a positive evidence bias as emerging from a confidence-specific heuristic, and alternative models where decision and confidence are generated by the same, Bayes-rational process.
Cultivating Inquiry in Advanced Mathematics with the Next Generation of Mathematics Professors
Authors: Alexander Anita N.
Published: June 2023

How can we shift the culture of lecture in university mathematics? The purpose of this study was to provide an intervention for mathematics majors on effective practice in teaching advanced mathematics, inspiring the next generation of mathematics professors to engage in inquiry and discourse so their future students can internalize critical concepts. This workshop will reflect those weekly seminars, beginning with puzzles to motivate topics, followed by exploring Introduction to Analysis, Number Theory, and Topology through the 5E Model. Participants completed weekly exit tickets, providing positive feedback regarding the Think-Pair-Share approach, and the Engage, Explore, and Explain aspects of the 5E Model. Survey responses indicated a strong belief in providing students with opportunities in class to collaborate and engage in discourse.
Mathematics for Everybody
Authors: Alpaslan Nurten , Alpaslan Emre
Published: June 2023

It is a big mistake to think like someone who is not good at mathematics, more precisely school mathematics, has a problem with his perception. Regardless of their academic success, every individual with a developed mathematical thinking system is successful in her/his job and is happy that her/his problem solving skills have also improved. It is a prejudice to think that mathematics is difficult. In childhood, each speech and behavior that emphasize the importance of mathematics in the environment send a message to the subconscious. Doing mathematics in art, music and physical education classes in primary education, also strengthens the subconscious mathematics anxiety. Avoiding mathematics in choosing subjects in secondary education, not being able to choose the right profession in the future, and doing a job that one does not like cause the individual to be unhappy and unproductive.

Preparing Students for Tomorrow: The Role of Technology
Authors: Burrill Gail
Published: June 2023

Research suggests technology can make a difference in mathematics teaching and learning, enabling students to build conceptual understanding and engaging them in problems of real interest. Interactive dynamic technology enables more students to have access to more mathematics, allows students to visualize mathematical ideas, and gives students agency to choose solution pathways that make sense to them. However, research also suggests many teachers allow students to use technology only after they have learned “by hand.” The increasing power of technology is a call to rethink what is important to learn in secondary mathematics, recognizing that much traditional content can be left to technology, shifting the focus to understanding and interpreting mathematical results. This paper describes ways to make such avision a reality, where we teach mathematics to prepare students for tomorrow instead of for a world that no longer exists.
Cumulative Knowledge Building in a Grade 12 Semiconductors Lesson: A Comparative Study between Online and Contact Mode of Teaching
Authors: Duma Angeline , Stephen Magdeline , Mushayikwa Emmanuel
Published: June 2023

As a consequence of the COVID-19 pandemic, most institutions in 2020 were forced to shift to online teaching. This paper seeks to understand whether the planned online sessions provided equivalent cumulative knowledge building experiences as the traditional contact sessions, particularly in Technical sciences. The study used a qualitative case study and data was collected in the form of pre-recorded observations for the online lesson and classroom observations for the contact lesson. To map the strengths of semantic gravity in both lessons, a translational device from the Legitimation Code Theory(LCT) was used. The study revealed that, while both lessons created conditions for cumulative knowledge building, contact sessions offered better opportunities because of the extended semantic gravity range and the teachers’ ability to explicitly define what constitutes knowing science. These findings suggest that online teachers could deliver effective lessons if they incorporated activities that include learner - teacher engagements to expand the semantic gravity range of their lessons. Key words: Online sessions, Contact sessions, Semantic gravity (SG), Legitimation Code Theory (LCT), Cumulative knowledge building
Developing Abstract Mathematical Thinkers Part 1 - Identifying the Challenges
Authors: Gordon John
Published: June 2023

Abstract mathematical thinkers in the fields of pure mathematics andtheoretical computer science have contributed significantly to the body ofknowledge that has fundamentally altered the course of human civilization and technological advances. Halpern and Butler [1] have stated that “our future depends on our ability to think critically in a world that is growing more complex day by day”, and that critical thinking skills “should be a priority.” They concluded that “the ability of our students to think critically and abstractly is a matter of national importance.”

Introduction to Confirmatory Factor Analysis (CFA)) using Lavaan in R Statistical Programming Language
Authors: Kanyongo Gibbs Y.
Published: June 2023

This workshop will cover how to perform a confirmatory factor analysis(CFA)using Lavaan. Lavaan, which stands for latent variable analysis is a free open-source commercial package in R, and it is developed and maintained by Yves Rosseel (Rosseel, 2012). It is used to fit a variety of latent variable models, including confirmatory factor analysis, structural equation modelling and latent growth curve models. CFA allows the researcher to test the hypothesis that a relationship between observed variables and their underlying latent constructs exists. CFA falls under the broad concept of factor analysis is divided broadly into two types, exploratory and confirmatory. Exploratory factor analysis (EFA), is used to understand the underlying dimensions or constructs of an unknown scale, while confirmatory factor analysis (CFA) is used to test hypothesis of a pre-determined factor structure of a previously developed scale.
From the Fundamental Theorem of Algebra to Monstrous Moonshine
Authors: Memling Johannes
Published: June 2023

With the use of artificial intelligence and machine learning that can solve and explain problems and can be integrated into existing workflows to support mathematical research, the focus of future courses in mathematics will be shifted towards a search for potential patterns and relations between mathematical objects and an effort to make sense of them. The AI uses the observations to guide the intuition towards solutions of potential conjectures. Future courses in mathematics will have higher levels of cognitive demand vs current technical problem-solving skills. As an example, we discuss how the Fundamental Theorem of Algebra within a small number of steps, reaches the monstrous moonshine, or moonshine theory, the unexpected connection between the monster group M and the modular j function. This connection is underlain by a vertex operator algebra, allowing physics to form a bridge between two (and more) mathematical areas.

Reflections on the Links between Innovative Practices in Mathematics Education and Democracy
Authors: Röj-Lindberg Ann-Sofi
Published: June 2023

Mathematics education can promote democratic competences and values, but also inhibit them, and create inequalities. A basic idea behind the promotion of democratic competences and attitudes is proposed by Vithal (1999): within a mathematics classroom where it is possible for students to experience democratic life students can learn to listen to others’ ideas, argue, take decisions, and critically analyse arguments made by authorities, e.g., the teacher. Aguilar and Zavaleta (2012) found three facets of mathematics education linked to democracy: a provider of critical mathematical skills, a source of values and attitudes, and a social gatekeeper. In this paper I discuss how mathematics teachers through innovative practices can foster a democratic competence in their students.

Mathematics Teachers Using ChatGPT for Designing Lessons Plans
Authors: Shriki Atara , Lavy Ilana
Published: June 2023

In November 2022, a kind of "revolution" took place. The prototype of the ChatGPT was launched and immediately hit the headlines. Soon the interest in the software reached our elementary school prospective mathematics teachers' (ESPMTs) classrooms, and they began to wonder whether artificial intelligence models will shortly replace teachers. So we initiated an experiment in which the ESPMTs "chatted" with ChatGPT about mathematics education and used it for designing lesson plans (LPs). Reflecting on their experience, the ESPMTs found that interacting with ChatGPT for designing LPs produced higher-quality LPs in a much shorter time. Nonetheless, they realized that lacking the human-like understanding and empathy that human teachers possess, as of today, artificial intelligence models cannot replace them. This paper presents examples from the chats and the ESPMTs' reflections.

The Effect of Gender and School Location on Early-Grade Children’s Mathematics Achievement in Halaba, Ethiopia
Authors: Tesfaye Aynalem
Published: June 2023

Mathematics education plays a vital role in equipping individuals with the necessary knowledge and skills that are useful for individual life. This study investigated early-grade (grade 1-4) children’s achievement in mathematics in relation to school location and gender. Data were collected from 423 earlygrade children and 9 principals at 9 primary schools in the Halaba zone in Ethiopia, through semi-structured interviews and the Early Grade Mathematics Assessment (EGMA) test. The findings of this study revealed that early-grade children’s achievement in mathematics as measured by EGMA is average (51.5%). There is a statistically significant difference between male and female students’ mean scores and the difference in the urban area showed a large gap however, the difference in relation to school location is not significant. There is a statistically significant effect for gender on students’ achievement with a large effect size (η 2 = .055) however, the effect of school location and the interaction effect of gender and school location were not statistically significant.
Problem situations for the teaching of school mathematics
Authors: Uzuriaga López Vivian Libeth , Sánchez Bedoya Héctor Gerardo , Castro Gordillo Walter F.
Published: June 2023

The problem situations built from the needs and interests of the students are adequate for teaching and learning mathematics. The situations encourage both students to abandon their passive role and commit to the construction of knowledge and teachers to give up their leading role and assume to be learning guides through intentional questions that promote the development of mathematical thinking. The situations are part of didactic units built within the framework of the postgraduate training in Education in la Universidad Tecnológica de Pereira-Colombia- of professors who teach mathematics. The research is qualitative and of a descriptive nature, which reports on the transformation of the teaching and learning processes of mathematics at different levels of schooling.
Digital Transformation, Benefits and Impacts for Teenagers Study of Student Perceptions of Cybercrime in Yogyakarta State Islamic Senior High School Students
Authors: Muhani Jibi  , Nur Aida  , Mipasya Ratu Plamesti
Published: June 2023

Digital transformation in the field of education provides tremendous benefits for both teachers and students, enabling easy access to a wide range of knowledge and supporting the teaching and learning process, including distance learning. However, digital transformation has had an impact on students, as they often become victims of cybercrime in the form of cyberbullying, which affects the mental well-being of the individuals involved. The purpose of this research is to understand the perception of students at MAN (Madrasah Aliyah Negeri) in Yogyakarta regarding the digitally-based teaching and learning process that utilizes smartphones for activities outside of the classroom. The research method employed in this study is qualitative descriptive research, which involves gathering information about existing phenomena, clearly defining the objectives to be achieved, planning the approach, and collecting data as the basis for creating a report. The research findings indicate that students' perception of social media crime/cybercrime reflects their experiences as observers, perpetrators, and victims. Factors such as individual characteristics, environment, and friendships influence students in engaging in these criminal activities. Students tend to be loyal to their friends, and victims often choose to remain silent. Effective prevention measures have been implemented in schools through collaboration with law enforcement authorities.
Book Review
Authors: Kozlowska Wiktoria
Published: June 2023

This review assesses Stephanie Oudghiri’s (2022) Struggling to Find Our Way: Rural Educators’ Experiences Working with and Caring for Latinx Students. Positioning her work in care and culturally responsive teaching, Oudghiri narratively examines the relationship between teachers, paraprofessionals, and Latinx students in a rural Midwestern elementary school. Story themes, analyzed under a framework of Swanson’s (1991, 1993) middle range theory of caring, uncover how educators’ personal and professional identities inform their ethics of care, or lack thereof, in the classroom. This review outlines Oudghiri’s successful use of narrative inquiry to craft an accessible, hopeful story that rural educators nationwide can learn from in order to better support their culturally diverse students.
GEÇİCİ KORUMA KAPSAMINDAKİ SURİYELİLERİN SOSYAL UYUM VE T.C. VATANDAŞLIĞINA İLİŞKİN GÖRÜŞLERİNİN DEĞERLENDİRİLMESİ: MERSİN ÖRNEĞİ
Authors: GÜNGÖR Mehmet , AÇIKYER Melek
Published: June 2023

2011 yılının Mart ayında başlayan Suriye'deki iç karışıklıklar sebebiyle, birçok Suriye vatandaşı ülkemize sığınmak zorunda kalmıştır. Türkiye bu sığınmacıları "Açık Kapı" politikası uygulayarak, geçici koruma kapsamında ülkeye kabul etmiştir. İlk yıllarda savaş mağdurundan kalıcılığa doğru ilerleyen göçmen kabulü son yıllarda yabancı düşmanlığına dönüşen toplumsal bir sorun olmuştur. Göçmenlerin toplumsal uyum konusundaki isteksizliği ve Türk toplumundaki göçmenlere ilişkin hoşnutsuzluk, yetkililer tarafından vatandaşlığa kabul kolaylaştırılarak çözülmeye çalışılmıştır. Yaşanan bu durum Mersin'de geçici koruma altında yaşayan Suriyelilerin sosyal uyum ve T.C. vatandaşlığına ilişkin görüşlerini araştırmanın nedenini de oluşturmaktadır. Çalışma, göçten en fazla etkilenen illerin başındaki Mersin ilinin Mezitli ilçesinde gerçekleştirilmiştir. Göç İdaresi Genel Müdürlüğüne göre geçici koruma altındaki Suriyeli sayısı 26.05.2022 tarihi itibariyle 3.763.652 olup Mersin’de ise bu rakam, 26 Mayıs 2022 tarihi itibariyle 243.411, Mersin’in yerel yöneticilerine göre ise bu rakam 500.000 i aşmıştır.

Bu çalışmada Mersin ili Mezitli ilçesinde yaşayan, geçici koruma kapsamındaki Suriyeli bireylerin uyum sorunlarını ve T.C. vatandaşlığı ilgili görüşlerini ve Türk vatandaşlığını tercih etme nedenlerinin tespiti amaçlanmıştır. Bunun için çalışmada nitel bir araştırma yöntemi olan Fenomenoloji (olgubilim) yöntemi kullanılmıştır. Araştırmada görüşme formu kullanılmış olup, ortak deneyimlere sahip, farklı demografik özellikteki 15 Suriyeli bireyle görüşülmüştür. Görüşme soruları yarı yapılandırılmış olarak hazırlanmış olup, çalışma sonunda değerlendirme yapılmış ve öneriler sunulmuştur.
Çağdaş Felsefi Gelişmeler Bağlamında Akıl ve Vahiy Kavramlarının Epistemolojik Öznellikleri
Authors: ÖZDEMİR Muhammet
Published: June 2023

Bu çalışmada akıl ile vahiy arasındaki ilişkilere yoğunlaşmış İslam felsefesi araştırmacısı, okuru ve düşünürlerinin öznellikleri incelenmektedir. Immanuel Kant araştırmalarında görünür olan “epistemolojik öznellik” kavramı bu metinde çağdaş özne felsefeleri çerçevesinde İslam felsefesi öznesine uygulanmaktadır. Söz konusu öznellik, bir taraftan Kant’ın “sentetik a priori” kavramını ilgilendirdiği için epistemolojinin meşruiyetini etkileyecek boyuttadır, diğer taraftan post-yapısalcı felsefede bilginin nesnesini dönüştürdüğü için merkezi bir öneme sahiptir. Post-kolonyal teoriden yararlanılarak gelişmekte olan ekonomi toplumlarının öznel tiniyle özdeşleştirilen İslam felsefesi yorumcusu akıl ve vahyi güncelleştirme pratikleri bakımından değerlendirilmektedir. Bu değerlendirmede önce bilgi sorununun geldiği çoklu hakikat içeriği anlatılmaktadır. İkinci olarak İslam felsefesindeki epistemolojinin içeriğine yer verilmektedir. Bu epistemolojide çoklu hakikat içeriği yerine evrensel bir hakikat arayışından kaynaklanan çıkmazın öznel koşulları eleştirel değerlendirilmektedir. Öznelliğin nesnel görünme şartları toplumsal süreçler ve kazanımlarla dolaylanmaksızın yeterince geçerli ve tutarlı oluşturulamamaktadır. Bu nedenle yerel kültüre ait dinamiklerin çağdaş epistemoloji içerisindeki konumlandırılması için akıl ve vahyin bağlam ve işlevine yoğunlaşmak gerekmektedir. Üçüncü olarak akıl ve vahyin bağlam ve işlevinden söz edilmektedir. Bu noktada akıl ve vahyin ayrı ayrı tanımları yapılmaya çalışılmaktadır. Dördüncü olarak akıl ile vahiy arasındaki ilişkilerin bu iki kavramı temsil eden insanların vücuda getirdikleri ilişkilerden ibaret olduğu gerçeği saptanıp açımlanmaktadır. Çalışmanın savına göre, epistemoloji büyük ölçüde öznel önerilerle toplumsal gereksinimlerin giderilebilmesi arasındaki alışverişten beslenmektedir. İslam felsefesi öznesi açısından akıl ve vahiy tarihten günümüze taşınırken gerçekçi toplumsal gereksinimlerle ilişkilendirme çerçevesinin ihmal edilmemesi gerekmektedir. Burada tarihin içerisine döndüğünü söyleyen epistemolojik öznellikler asıl yaptıklarını söylemiş olmamaktadırlar. Çalışma özne felsefelerinin tartışma bağlamından hareketle İslam felsefesi öznesini akıl ve vahye dayanan epistemoloji çerçevesinde bilgi sosyolojisinin içine çekmeye gayret etmektedir.

Patrones espaciotemporales de la población en España (1998-2021).
Authors: De Cos Guerra Olga
Published: June 2023

La despoblación es un tema de investigación consolidado y más recientemente también es protagonista en las agendas políticas. En este contexto, se propone una metodología de análisis de patrones emergentes para revelar tendencias espaciotemporales significativas y matizar los patrones de la pérdida de población a nivel municipal entre 1998 y 2021. A partir de fuentes convencionales, como el Padrón Municipal de Habitantes, los resultados demuestran un comportamiento sistémico bipolar frío-caliente, más equilibrado en su dimensión superficial que poblacional. Se confirma la existencia de dos realidades norte-sur en la España que se despuebla, concentrándose en la mitad norte los patrones fríos más marcados (crecientes y consecutivos). El estudio aporta una metodología escalable y exportable a otros periodos y/o territorios.
CAN INVESTOR ATTENTION DEFUSE THE RISK OF CORPORATE ZOMBIFICATION? – EMPIRICAL EVIDENCE FROM LISTED COMPANIES IN CHINA
Authors: Lin Yan , Zhang Xinjing
Published: June 2023

Solving the risk of zombification of enterprises and relieving their business difficulties, as a key element of supply-side structural reform, is the pain point of the conversion of old and new dynamic energy and the difficulty of economic transformation and upgrading. In the Internet era, the impact on business operations is also expanding with the widening of investor attention channels. This paper selects Chinese listed companies from 2011–2020 as a research sample, and the empirical results show that, first, investor attention can effectively reduce the risk of transforming enterprises into zombie enterprises, i.e., the risk of corporate zombification decreases as the level of investor attention increases; second, there is heterogeneity in the role of investor attention in resolving the risk of corporate zombification; third, further mechanism tests find that along with Third, further mechanistic tests reveal that as the level of investor attention increases, the level of environmental uncertainty decreases and the annual market value of individual stocks increases, thereby reducing the risk of corporate zombification. The findings of this paper provide theoretical support and empirical evidence for further improving the risk mitigation of corporate zombification, promoting the “de-emphasis” of enterprises, and leading the high-quality and healthy development of enterprises.

Update on the United States Nuclear Strategy: from NPR 2018 to NPR 2022
Authors: Potočňák Adam
Published: June 2023

The article follows the author's comparative analysis of American and Russian nuclear doctrines and armaments from the fall of 2021. It presents the current nuclear strategy of the United States of America based on a content analysis of three specific areas of the updated version of the Nuclear Posture Review. Applying interpretive analysis and a rich secondary sources apparatus, the author also reflects on his 2021-formulated assumptions and expectations about the further development of American nuclear strategy under President Joe Biden. The author analyzes the influence of the presidential administration's ideological and political ambitions together with the decisive geopolitical events of 2022 and concludes that mainly due to the second factor, the current shape of American nuclear strategy has not undergone any revolutionary changes and continues to maintain a long-standing continuity and consensus about its basic principles.
Does the government's defence funding bill really only create an unenforceable political commitment?
Authors: Kudrna Jan
Published: June 2023

The article is devoted to the draft law on defence financing, which aims to oblige the government to allocate an amount of at least 2% of GDP to defence in every draft law on the state budget. During the inter-ministerial comment procedure, the Supreme Audit Office expressed doubts whether the draft means anything more than an unenforceable political commitment in relation to the Chamber of Deputies". The article convincingly demonstrates, with the help of legal argumentation and interpretation of the Constitution of the Czech Republic, the Rules of Procedure of the Chamber of Deputies, as well as the established case law of the Constitutional Court of the Czech Republic, that if approved, the Chamber of Deputies will also be bound by the Defence Financing Act when approving the state budget. To do otherwise would violate constitutionality.
French military interventions in MENAP countries during the 2010s
Authors: Eichler Jan
Published: June 2023

The article is about six French Special Military Operations (SMOs) that were conducted in Islamic countries in the MENA region between 2011 and 2022. It provides an explanation of their historical, geopolitical, and military contexts while also assessing their compliance with international law. The text introduces two innovative concepts, the Holland doctrine and the Macron doctrine, and analyses both their successes and failures. Ultimately, the article concludes by addressing the question of why these SMOs achieved military success but failed to meet political objectives, resulting in a significant disillusionment among French political and military elites, as well as the participating soldiers.
Preface to the Second Koala Retrovirus Workshop online 25–27 May 2021. In Proceedings of the Second Koala Retrovirus Workshop, ed. D. E. Alquezar-Planas, D. P. Higgins, C. L. Singleton, and A. D. Greenwood

Published: June 2023

In 2013, the first Koala Retrovirus Workshop was held in San Diego, bringing together biology and veterinary specialists to assess and discuss the state of knowledge on koala retrovirus (KoRV) and to form professional bridges and networks. Tremendous progress has been made in the years following the San Diego meeting, in large part due to ongoing international collaborations that were fostered to study KoRV. This volume presents peer-reviewed papers from most of the oral presentations and discussions held during the Second Koala Retrovirus Workshop in 2021. Unfortunately, the COVID-19 pandemic forced the workshop into an online only format. Despite this limitation, three days of discussions based on workshop presentations highlighted current knowledge and important information gaps, culminating in suggested ways forward, all summarized in this volume.
Koala retrovirus infection and disease in South Australian koala (Phascolarctos cinereus) populations. In Proceedings of the Second Koala Retrovirus Workshop, ed. D. E. Alquezar-Planas, D. P. Higgins, C. L. Singleton, and A. D. Greenwood
Authors: Speight Natasha
Published: June 2023

Koala retrovirus (KoRV) infection, endogenous in all northern koalas (Phascolarctos cinereus), has been found to occur at lower, but increasing, prevalence in the Kangaroo Island and Mount Lofty Ranges koala populations in South Australia. Proviral and viral loads are also lower than in Queensland koalas, which may be due to exogenous spread of infection, or may be related to the variable presence of viral genes and fragmented expression that has been found in positive Mount Lofty Ranges koalas. However, high proviral loads and full expression across the KoRV genome in South Australian koalas has been found in individuals with neoplasia, particularly lymphoma, which can be as extensive and as severe as that observed in northern koalas. KoRV-A is the predominant subtype and no association with chlamydial status has been found except that high viral loads correlate with severity of chlamydiosis. Based on the complexity of KoRV infections in South Australian koalas, further research is needed to understand the differences in transmission and pathogenesis that occur.
Evolution of Tourist Regionalization in Bulgaria: Objectives, Approaches and Results
Authors: Marinov Vasil , Dogramadjieva Elka , Assenova Mariana
Published: June 2023

The issue of defining tourist regions in Bulgaria and their management has been discussed in the country over the last 50 years and is still relevant nowadays. So far, many attempts have been made to develop an acceptable solution in regards of the nature, functions and scope of the tourist regions in the country but for a number of reasons and in different political and economic context they have not been successful. At the same time, the need for tourist regionalization in Bulgaria has been recognized by almost all stakeholders in the tourism sector over the last 10-15 years. The aim of this article is to review and compare the existing tourist regionalization schemes of the country, thus allowing to trace the evolution of tourist regionalization and to highlight the main theoretical deficiencies, as well as the underestimation of scientific principles and approaches that underlie its practical inapplicability. The comparative analysis covers all concepts developed over the last 50 years that present a specific scheme of tourist regions, taking into account the relevant explanatory notes. For the purpose of the comparison, 9 criteria have been selected, which refer both to the approach and objectives, and to the specific schemes and their compliance with basic practical requirements. The results of the comparative analysis are chronologically presented in a table for their clearer and easier perception. The analysis has shown that the numerous tourist regionalization concepts of Bulgaria differ greatly in objectives, approaches and tools applied, and respectively provide different results in terms of country coverage, taxonomy, degree of the schemes’ details, etc. It has also shown significant differences in the tourist structuring of the country’s territory, which are more visible in the period after 1990. The development of a methodologically sound, politically acceptable and applicable scheme of tourist regions is a difficult political and scientific task but it is achievable through a reasonable compromise between the theory and the views of key stakeholders, in compliance with legislation and in the context of its objectives. The effectiveness of tourist regionalization for the purposes of tourism policy and destination marketing ultimately depends on its practical implementation. Otherwise, it could be considered merely as an “academic” exercise, which may have a scientific but not an applied value.
Characteristics of the information provision of spatial planning

Published: June 2023

One of the spheres where our country marked the most serious stagnation during theperiod of transition tomarket economy is the spatial and urban planning. Currently the campaign of preparation of new urban master plans for Bulgarian municipalities is in its peak. The better knowledge of the sources of information and all the specific characteristics of the different information arrays, as well the specific procedures of data processing, is very important for achieving good results. The purpose of this study is to mark all the specific characteristics of the data,that we need, and the procedures of their processingwith a view to providing the necessary information base for the development of the municipality's Master Plan. Here we mark all the main problems which may occur in the process of information provision of the project,the compatibility of the data from different sources with a view to achieving the required quality of the final products.
Development of the land cover in Mala Planina
Authors: Assenov Assen , Grigorov Borislav
Published: June 2023

The current study investigates the development of the land cover in the mountainous territory of Mala Planina, located in the western part of Stara Planina. It focuses on cameral and terrain research in which basis is the CORINE Land Cover (CLC), initiated by the European Union. All existing databases for the country were applied (CLC 1990, 2000, 2006 and 2012). Each updated version of the CLC data shows typical transformation in Mala Planina’s land cover. A thorough investigation is made about all parts of the mountain and published within the results. Four GIS derived maps are published. The results show that the most significant dissonance occurs between CLC 1990 and the rest CORINE Land Cover data sets (CLC 2000; 2006; 2012) and the reason for the imparity lies mainly in the extensive timeframe. Almost no distinction is observed, when we compare CLC 2006 and 2012. The most common changes are connected with the transition to land principally occupied by agriculture, with significant areas of natural vegetation, which is explained by the decreasing number of population and abandonment of the agricultural areas.

Global megalopolis: problems and trends or how much can a city grow?
Authors: Naydenov Kliment
Published: June 2023

The number of countries that are considered highly urbanized has increased dramatically in recent decades and is expected to continue to grow in the coming decades. The world is entering the era of sustainable urbanization. By 2030, the world is predicted to have 41 mega cities. Megalopolis is the laboratory of a new urban way of life that spreads out into the civilized world. Today, it is a uniting of all activities related to the production of value added. They are the basis of what we call the globalization of the economy. Continued urbanization means that societies must continue to provide more food, more employment, more housing and more transport to the growing number of citizens. Megalopolis today is becoming a vulnerable place and is directly affected by climate change. If climate change continues and the appropriate measures are not taken, the urban way of life will depend on different natural cataclysms such as storms, droughts, as well as rising sea levels and heat waves. Today, urbanization is uncontrollable, megalopolises are growing without planning, and the urban spaces in the world are extremely small.
Karst Waters in Northwestern Bulgaria
Authors: Temelkova Maria
Published: June 2023

Karst waters are widespread in the studied area. In the area of the Misia Platform karst aquifers are formed, and in the zones of the Pre-Balkan and the Western Balkans are numerous karst basins formed. The aim of this work is to evaluate the resource in the area and the possibilities for its use in the water management sector. A map of the karst basins in the area is drawn up and a table with their characteristics is made. For this purpose, cartographic methods have been applied using GIS technology. On the basis of the collected data, recommendations have been made for the more efficient utilization of karst waters in the area.
Landscape-Geochemical Research of the Mud Volcanoes in the Sazliyka River Valley
Authors: Penin Rumen , Zhelev Dimitar
Published: June 2023

The mud volcanoes in the valley of the Sazliyka River and its tributaries are a geological phenomenon that has attracted scientific attention for decades. They are a specific element for the local lowland landscapes. This study focuses on the content of heavy metals in mud volcanoes. The total content of the elements: copper (Cu), zinc (Zn), lead (Pb), manganese (Mn), nickel (Ni), cobalt (Co) and chromium (Cr) in mg/kg (ppm) has been identified. The obtained contents have been analyzed by the clarke of concentration indicator (KK) - the ratio between the content of a given element in a given natural component (soil horizon, vegetation, surface water, etc.) - Ci, and a clarke of the same element in the lithosphere - K: The researched geochemical nature of the local litho-geochemical and soil-geochemical conditions may have been influenced by the geochemical specifics of the materials entering the earth’s surface upon activation of mud volcanoes in the area of study. They might have an impact on the geochemical structure of the bottom sediments in the local river currents and hence the influence on the main river artery Sazliyka River. The obtained results give to some extent information about the geochemical nature of this rare phenomenon for our country.

Practice-applied aspects of the regional research methods in the territorial unit exploration
Authors: Vladeva Rositsa , Vladev Ivaylo
Published: June 2023

A characteristic feature of the scientific toolkit of geographic science is the ability to study objects, phenomena and processes simultaneously in their vertical and horizontal hierarchy. It is precisely such territorial configurations that can be identified by exploring one of the components of the territorial systems that is related to the population, its location and the specifics of the particular demographic situation. The results are aimed at creating and applying a model that can more effectively manage territorial systems and administrative units of different rank and hierarchy. The proposed model will complement the researches in the methodology for determining the gravitational zones, their typology and prognosis for the development of the demographic situation.
The need for changes in the administrative-territorial division in the Republic of Bulgaria in the context of its membership in the European Union
Authors: Lichev Tihomir
Published: June 2023

The present study examines the main features of the implemented regional policy in the Republic of Bulgaria. The main stages of its implementation are followed. Its relationship with the separate administrative-territorial divisions is being established. The peculiarities of the spatial planning of the country, which was conducted with the purpose of rational development of the territory, are considered. In its history, the country's ATD is constantly changing. In the present study, in a chronological way, the ideas on the division of the country into separate territorial units - municipality, district, planning regions, (statistical regions) are being chronologically analyzed. Due to the ongoing acute demographic crisis and the lack of economic and administrative capacity of individual territorial units, their consolidation is necessary. The opportunities for this process are outlined. In recent years, in connection with the country's membership in the EU and the requirements for absorption of European funding, it is necessary to consolidate the statistical regions in the country. The different options, as well as their advantages and disadvantages are mentioned.
The painting – unproven or little-known talent of professor Anastas Ishirkov
Authors: Mihaylov Pelo
Published: June 2023

Prof. Anastas Ishirkov, apart from a remarkable scientist, was also a good writer. Only recently did it become known that he was among the first tourists to have climbed Cherni Vrah in August 1894. The object of the article is Ishirkov's other talent – painting. A small drawing on a postcard is testified to him. An unknown archivist considers Anastas Ishirkov as its creator. Because of this, in the only one account to his authorship the adjective ’unproven’ is used. And his pictorial talent, albeit a little, is already known, as the watercolor have already been seen by a considerable number of people. The drawing is a seal of a lifetime of Bulgarian students in Leipzig. Memorable texts testify that an important part of the student's being was formed by the picnics on Sunday in the vicinity of the city. Among the characters of the painting are the poet Pencho Slaveikov, the lawyer Joseph Fadenhecht, the author of the Bulgarian anthem Tsvetan Radoslavov and Ishirkov himself. Two pictures also show the recipient of the card – Ivan Ivanchev from Lovech. It is possible that unsigned cartoons in the humorous newspaper „Farkat List“ are also the result of the drawing talent of Anastas Ishirkov.
