Our lives are entirely digitalized. These changes make many things faster, easier, and more efficient. But keeping pace with these changes demands a lot from us, and not everyone succeeds. There are people who prefer to go to the bank to make a transfer, leave the programming to the experts, send their tax return by mail, and only use their smartphone to make phone calls. They don't want to keep pace, or maybe they can't. They haven't learned these things. Others, younger people, grow up as "digital natives" surrounded by digital devices, tools, and processes. But does that mean they really know how to use them? Or do they also need digital education? But what does successful digital education actually look like? Does it teach us how to use a tablet, how to google properly, and how to write Excel spreadsheets? Perhaps it's about more than that. It's about understanding the comprehensive change that has been taking hold of our world since it was broken down into digital ones and zeros and rebuilt virtually. But how do we learn to live in a world of digitality - with all that it entails, and to our benefit? For the new issue of "Portal Wissen", we looked around at the university and interviewed researchers about the role that the connection between digitalization and learning plays in the research of various disciplines. We spoke to Katharina Scheiter, Professor of Digital Education, about the future of German schools and had several experts show us examples of how digital tools can improve learning in schools. We also talked to computer science and agricultural researchers about how even experienced farmers can still learn a lot about their land and their work thanks to digital tools. We spoke to educational researchers who are using big data to analyze how boys and girls learn and what the possible causes for differences are. Education and political scientist Nina Kolleck, on the other hand, looks at education against the backdrop of globalization and relies on the analysis of large amounts of social media data. Of course, we don't lose sight of the diversity of research at the University of Potsdam. We learn, for example, what alternatives to antibiotics could soon be available. This magazine also looks at stress and how it makes us ill as well as the research into sustainable ore extraction. A new feature of our magazine is a whole series of shorter articles that invite you to browse and read: from research news and photographic insights into laboratories to simple explanations of complex phenomena and outlooks into the wider world of research to a small scientific utopia and a personal thanks to research.

Despite its high prevalence, the precise origins of PMS remain elusive, with influences ranging from hormonal fluctuations to cognitive, social, and cultural factors (Hunter, 2007; Matsumoto et al., 2013). Biologically, hormonal fluctuations, particularly in gonadal steroids, are commonly believed to be implicated in PMS, with the central factor being varying susceptibilities to the fluctuations between individuals and cycles (Rapkin \& Akopians, 2012). Allopregnanolone (ALLO), a neuroactive steroid and progesterone metabolite, has emerged as a potential link to PMS symptoms (Hantsoo \& Epperson, 2020). ALLO is a positive allosteric modulator of the GABAA receptor, influencing inhibitory communication (Rupprecht, 2003; Andr{\´e}en et al., 2006). Different susceptibility to ALLO fluctuations throughout the cycle may lead to reduced GABAergic signal transmission during the luteal phase of the menstrual cycle. The GABAergic system's broad influence leads to a number of affected physiological systems, including a consistent reduction in vagally mediated heart rate variability (vmHRV) during the luteal phase (Schmalenberger et al., 2019). This reduction in vmHRV is more pronounced in individuals with high PMS symptoms (Baker et al., 2008; Matsumoto et al., 2007). Fear conditioning studies have shown inconsistent associations with cycle phases, suggesting a complex interplay between physiological parameters and PMS-related symptoms (Carpenter et al., 2022; Epperson et al., 2007; Milad et al., 2006). The neurovisceral integration model posits that vmHRV reflects the capacity of the central autonomous network (CAN), which is responsible for regulatory processes on behavioral, cognitive, and autonomous levels (Thayer \& Lane, 2000, 2009). Fear learning, mediated within the CAN, is suggested to be indicative of vmHRV's capacity for successful VI regulation (Battaglia \& Thayer, 2022). Given the GABAergic mediation of central inhibitory functional connectivity in the CAN, which may be affected by ALLO fluctuations, this thesis proposes that fluctuating CAN activity in the luteal phase contributes to diverse aversive symptoms in PMS. A research program was designed to empirically test these propositions. Study 1 investigated fear discrimination during different menstrual cycle phases and its interaction with vmHRV, revealing nuanced effects on acoustic startle response and skin conductance response. While there was heightened fear discrimination in acoustic startle responses in participants in the luteal phase, there was an interaction between menstrual cycle phase and vmHRV in skin conductance responses. In this measure, heightened fear discrimination during the luteal phase was only visible in individuals with high resting vmHRV; those with low vmHRV showed reduced fear discrimination and higher overall responses. Despite affecting the vast majority of menstruating people, there are very limited tools available to reliably assess these symptoms in the German speaking area. Study 2 aimed at closing this gap, by translating and validating a German version of the short version of the Premenstrual Assessment Form (Allen et al., 1991), providing a reliable tool for future investigations, which closes the gap in PMS questionnaires in the German-speaking research area. Study 3 employed a diary study paradigm to explore daily associations between vmHRV and PMS symptoms. The results showed clear simultaneous fluctuations between the two constructs with a peak in PMS and a low point in vmHRV a few days before menstruation onset. The association between vmHRV and PMS was driven by psychological PMS symptoms. Based on the theoretical considerations regarding the neurovisceral perspective on PMS, another interesting construct to consider is attentional control, as it is closely related to functions of the CAN. Study 4 delved into attentional control and vmHRV differences between menstrual cycle phases, demonstrating an interaction between cycle phase and PMS symptoms. In a pilot, we found reduced vmHRV and attentional control during the luteal phase only in participants who reported strong PMS. While Studies 1-4 provided evidence for the mechanisms underlying PMS, Studies 5 and 6 investigated short- and long-term intervention protocols to ameliorate PMS symptomatology. Study 5 explored the potential of heart rate variability biofeedback (HRVB) in alleviating PMS symptoms and a number of other outcome measures. In a waitlist-control design, participants underwent a 4-week smartphone-based HRVB intervention. The results revealed positive effects on PMS, with larger effect sizes on psychological symptoms, as well as on depressive symptoms, anxiety/stress and attentional control. Finally, Study 6 examined the acute effects of HRVB on attentional control. The study found positive impact but only in highly stressed individuals. The thesis, based on this comprehensive research program, expands our understanding of PMS as an outcome of CAN fluctuations mediated by GABAA receptor reactivity. The results largely support the model. These findings not only deepen our understanding of PMS but also offer potential avenues for therapeutic interventions. The promising results of smartphone-based HRVB training suggest a non-pharmacological approach to managing PMS symptoms, although further research is needed to confirm its efficacy. In conclusion, this thesis illuminates the complex web of factors contributing to PMS, providing valuable insights into its etiological underpinnings and potential interventions. By elucidating the relationships between hormonal fluctuations, CAN activity, and psychological responses, this research contributes to more effective treatments for individuals grappling with the challenges of PMS.

Beide Kammern m{\"u}ssen dabei der Gesetzgebung zustimmen. Dieses von Steffen Ganghof klassifizierte System erg{\"a}nzt g{\"a}ngige Regierungssystemtypologien, wie sie beispielsweise von David Samuels und Matthew Shugart genutzt werden. Der Semi-Parlamentarismus ist der logische Gegenpart zum Semi-Pr{\"a}sidentialismus, bei dem nur ein Teil der Exekutive von der Legislative abh{\"a}ngt, w{\"a}hrend im Semi-Parlamentarismus die Exekutive von nur einem Teil der Legislative abh{\"a}ngt. Der Semi-Parlamentarismus verk{\"o}rpert so ein System der Gewaltenteilung ohne einen exekutiven Personalismus, wie er durch die Direktwahl und Unabh{\"a}ngigkeit der Regierungchef:in im Pr{\"a}sidentialismus hervorgerufen wird. Dadurch ist der Semi-Parlamentarismus geeignet, Unterschiede zwischen Parlamentarismus und Pr{\"a}sidentialismus auf den separaten Einfluss der Gewaltenteilung und des exekutiven Personalismus zur{\"u}ckzuf{\"u}hren. Die Untersuchung des Semi-Parlamentarismus ist daher f{\"u}r die Regierungssystemliteratur insgesamt von Bedeutung. Der Semi-Parlamentarismus ist dabei kein rein theoretisches Konstrukt, sondern existiert im australischen Bundesstaat, den australischen Substaaten und Japan. Die vorliegende Dissertation untersucht erstmals umfassend die Gesetzgebung der semi-parlamentarischen Staaten als solchen. Der Fokus liegt dabei auf den zweiten Kammern, da diese durch die Unabh{\"a}ngigkeit von der Regierung der eigentliche Ort der Gesetzgebung sind. Die Gesetzgebung in Parlamentarismus und Pr{\"a}sidentialismus unterscheidet sich insbesondere in der Geschlossenheit der Parteien, der Koalitionsbildung und dem legislativen Erfolg der Regierungen. Diese Punkte sind daher auch von besonderem Interesse bei der Analyse des Semi-Parlamentarismus. Die semi-parlamentarischen Staaten unterscheiden sich auch untereinander teilweise erheblich in der institutionellen Ausgestaltung wie den Wahlsystemen oder den verf{\"u}gbaren Mitteln zur {\"U}berwindung von Blockadesituationen. Die Darstellung und die Analyse der Auswirkungen dieser Unterschiede auf die Gesetzgebung ist neben dem Vergleich des Semi-Parlamentarismus mit anderen Systemen das zweite wesentliche Ziel dieser Arbeit. Als Fundament der Analyse habe ich einen umfangreichen Datensatz erhoben, der alle Legislaturperioden der australischen Staaten zwischen 1997 und 2019 umfasst. Wesentliche Bestandteile des Datensatzes sind alle namentlichen Abstimmungen beider Kammern, alle eingebrachten und verabschiedeten Gesetzen der Regierung sowie die mit Hilfe eines Expert-Surveys erhobenen Parteipositionen in den relevanten Politikfeldern auf substaatlicher Ebene. Haupts{\"a}chlich mit der Hilfe von Mixed-Effects- und Fractional-Response-Analysen kann ich so zeigen, dass der Semi-Parlamentarismus in vielen Aspekten eher parlamentarischen als pr{\"a}sidentiellen Systemen gleicht. Nur die Koalitionsbildung erfolgt deutlich flexibler und unterscheidet sich daher von der typischen parlamentarischen Koalitionsbildung. Die Analysen legen nahe, dass wesentliche Unterschiede zwischen Parlamentarismus und Pr{\"a}sidentialismus eher auf den exekutiven Personalismus als auf die Gewaltenteilung zur{\"u}ckzuf{\"u}hren sind. Zwischen den semi-parlamentarischen Staaten scheinen vor allem die Kontrolle des Medians beider Parlamentskammern durch die Regierung und die M{\"o}glichkeit der Regierung, die zweite Kammer mitaufzul{\"o}sen, zu entscheidenden Unterschieden in der Gesetzgebung zu f{\"u}hren. Die Kontrolle des Medians erm{\"o}glicht eine flexible Koalitionsbildung und f{\"u}hrt zu h{\"o}heren legislativen Erfolgsraten.

Nevertheless, its success has so far been coupled with the availability of large annotated (labelled) datasets. This is a requirement that is difficult to fulfil in several domains, such as in medical imaging. Annotation costs form a barrier in extending deep learning to clinically-relevant use cases. The labels associated with medical images are scarce, since the generation of expert annotations of multimodal patient data at scale is non-trivial, expensive, and time-consuming. This substantiates the need for algorithms that learn from the increasing amounts of unlabeled data. Self-supervised representation learning algorithms offer a pertinent solution, as they allow solving real-world (downstream) deep learning tasks with fewer annotations. Self-supervised approaches leverage unlabeled samples to acquire generic features about different concepts, enabling annotation-efficient downstream task solving subsequently. Nevertheless, medical images present multiple unique and inherent challenges for existing self-supervised learning approaches, which we seek to address in this thesis: (i) medical images are multimodal, and their multiple modalities are heterogeneous in nature and imbalanced in quantities, e.g. MRI and CT; (ii) medical scans are multi-dimensional, often in 3D instead of 2D; (iii) disease patterns in medical scans are numerous and their incidence exhibits a long-tail distribution, so it is oftentimes essential to fuse knowledge from different data modalities, e.g. genomics or clinical data, to capture disease traits more comprehensively; (iv) Medical scans usually exhibit more uniform color density distributions, e.g. in dental X-Rays, than natural images. Our proposed self-supervised methods meet these challenges, besides significantly reducing the amounts of required annotations. We evaluate our self-supervised methods on a wide array of medical imaging applications and tasks. Our experimental results demonstrate the obtained gains in both annotation-efficiency and performance; our proposed methods outperform many approaches from related literature. Additionally, in case of fusion with genetic modalities, our methods also allow for cross-modal interpretability. In this thesis, not only we show that self-supervised learning is capable of mitigating manual annotation costs, but also our proposed solutions demonstrate how to better utilize it in the medical imaging domain.

Positioning systems such as GPS enable the tracking of various moving objects' trajectories, which are usually represented by a chronologically ordered sequence of observed locations. The analysis of movement patterns based on detailed positional information creates opportunities for applications that can improve business decisions and processes in a broad spectrum of industries (e.g., transportation, traffic control, or medicine). Due to the large data volumes generated in these applications, the cost-efficient storage of spatio-temporal data is desirable, especially when in-memory database systems are used to achieve interactive performance requirements. To efficiently utilize the available DRAM capacities, modern database systems support various tuning possibilities to reduce the memory footprint (e.g., data compression) or increase performance (e.g., additional indexes structures). By considering horizontal data partitioning, we can independently apply different tuning options on a fine-grained level. However, the selection of cost and performance-balancing configurations is challenging, due to the vast number of possible setups consisting of mutually dependent individual decisions. In this thesis, we introduce multiple approaches to improve spatio-temporal data management by automatically optimizing diverse tuning options for the application-specific access patterns and data characteristics. Our contributions are as follows: (1) We introduce a novel approach to determine fine-grained table configurations for spatio-temporal workloads. Our linear programming (LP) approach jointly optimizes the (i) data compression, (ii) ordering, (iii) indexing, and (iv) tiering. We propose different models which address cost dependencies at different levels of accuracy to compute optimized tuning configurations for a given workload, memory budgets, and data characteristics. To yield maintainable and robust configurations, we further extend our LP-based approach to incorporate reconfiguration costs as well as optimizations for multiple potential workload scenarios. (2) To optimize the storage layout of timestamps in columnar databases, we present a heuristic approach for the workload-driven combined selection of a data layout and compression scheme. By considering attribute decomposition strategies, we are able to apply application-specific optimizations that reduce the memory footprint and improve performance. (3) We introduce an approach that leverages past trajectory data to improve the dispatch processes of transportation network companies. Based on location probabilities, we developed risk-averse dispatch strategies that reduce critical delays. (4) Finally, we used the use case of a transportation network company to evaluate our database optimizations on a real-world dataset. We demonstrate that workload-driven fine-grained optimizations allow us to reduce the memory footprint (up to 71\% by equal performance) or increase the performance (up to 90\% by equal memory size) compared to established rule-based heuristics. Individually, our contributions provide novel approaches to the current challenges in spatio-temporal data mining and database research. Combining them allows in-memory databases to store and process spatio-temporal data more cost-efficiently.}, language = {en} } @phdthesis{Frank2024, author = {Frank, Mario}, title = {On synthesising Linux kernel module components from Coq formalisations}, doi = {10.25932/publishup-64255}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-642558}, school = {Universit{\"a}t Potsdam}, pages = {IX, 78}, year = {2024}, abstract = {This thesis presents an attempt to use source code synthesised from Coq formalisations of device drivers for existing (micro)kernel operating systems, with a particular focus on the Linux Kernel. In the first part, the technical background and related work are described. The focus is here on the possible approaches to synthesising certified software with Coq, namely the extraction to functional languages using the Coq extraction plugin and the extraction to Clight code using the CertiCoq plugin. It is noted that the implementation of CertiCoq is verified, whereas this is not the case for the Coq extraction plugin. Consequently, there is a correctness guarantee for the generated Clight code which does not hold for the code being generated by the Coq extraction plugin. Furthermore, the differences between user space and kernel space software are discussed in relation to Linux device drivers. It is elaborated that it is not possible to generate working Linux kernel module components using the Coq extraction plugin without significant modifications. In contrast, it is possible to produce working user space drivers both with the Coq extraction plugin and CertiCoq. The subsequent parts describe the main contributions of the thesis. In the second part, it is demonstrated how to extend the Coq extraction plugin to synthesise foreign function calls between the functional language OCaml and the imperative language C. This approach has the potential to improve the type-safety of user space drivers. Furthermore, it is shown that the code being synthesised by CertiCoq cannot be used in kernel space without modifications to the necessary runtime. Consequently, the necessary modifications to the runtimes of CertiCoq and VeriFFI are introduced, resulting in the runtimes becoming compatible components of a Linux kernel module. Furthermore, justifications for the transformations are provided and possible further extensions to both plugins and solutions to failing garbage collection calls in kernel space are discussed. The third part presents a proof of concept device driver for the Linux Kernel. To achieve this, the event handler of the original PC Speaker driver is partially formalised in Coq. Furthermore, some relevant formal properties of the formalised functionality are discussed. Subsequently, a kernel module is defined, utilising the modified variants of CertiCoq and VeriFFI to compile a working device driver. It is furthermore shown that it is possible to compile the synthesised code with CompCert, thereby extending the guarantee of correctness to the assembly layer. This is followed by a performance evaluation that compares a naive formalisation of the PC speaker functionality with the original PC Speaker driver pointing out the weaknesses in the formalisation and possible improvements.

Cellulose microfibrils, the principal load-bearing components is the major component of the primary cell wall, whose synthesis is mediated by microtubule-associated CELLULOSE SYNTHASE (CESA) COMPLEXES (CSC). Previous studies have shown that CSC interacting proteins COMPANION OF CELLULOSE SYNTHASE (CC) facilitate sustained cellulose synthesis during salt stress by promoting repolymerization of cortical microtubules. However, our understanding of cellulose synthesis during salt stress remains incomplete. In this study, a pull-down of CC1 protein led to the identification of a novel interactor, termed LEA-like. Phylogenetic analysis revealed that LEA-like belongs to the LATE EMBRYOGENESIS ABUNDANT (LEA) protein family, specifically to the LEA_2 subgroup, showing a close relationship with the CC proteins. Roots of the double mutants lea-like and its closest homolog emb3135 exhibited hypersensitivity when grown on cellulose synthesis inhibitors. Further analysis of higher-order mutants of lea-like, emb3135, and cesa6 demonstrated a genetic interaction between them indicating a significant role in cellulose synthesis. Live-cell imaging revealed that both LEA-like and EMB3135 migrated with the CSC at the plasma membrane along microtubule tracks in control and oryzalin-treated conditions which destabilize microtubules, suggesting a tight interaction. Investigation of fluorescently labeled lines of different domains of the LEA-like protein revealed that the N-terminal cytosolic domain of LEA-like colocalizes with microtubules, suggesting a physical association between the two. Considering the established role of LEA proteins in abiotic stress tolerance, we performed phenotypic analysis of the mutant under various stresses. Growth of double mutants of lea-like and emb3135 on NaCl containing media resulted in swelling of root cell indicating a putative role in salt stress tolerance. Supportive of this the quadruple mutant, lacking LEA-like, EMB3135, CC1, and CC2 proteins, exhibited a severe root growth defect on NaCl media compared to control conditions. Live-cell imaging revealed that under salt stress, the LEA-like protein forms aggregates in the plasma membrane. In conclusion, this study has unveiled two novel interactors of the CSC that act with the CC proteins that regulate plant growth in response to salt stress providing new insights into the intricate regulation of cellulose synthesis, particularly under such conditions.}, language = {en} } @phdthesis{Apodiakou2024, author = {Apodiakou, Anastasia}, title = {Analysis of the regulation of SDI genes, unravelling the role of the SLIM1 transcription factor, and the SNRK3.15 kinase in Arabidopsis under sulfur deprivation}, school = {Universit{\"a}t Potsdam}, pages = {141}, year = {2024}, language = {en} } @phdthesis{Hagemann2024, author = {Hagemann, Justus}, title = {On the molecular evolution of sengis (Macroscelidea)}, doi = {10.25932/publishup-64197}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-641975}, school = {Universit{\"a}t Potsdam}, pages = {xiii, 144}, year = {2024}, abstract = {This thesis focuses on the molecular evolution of Macroscelidea, commonly referred to as sengis. Sengis are a mammalian order belonging to the Afrotherians, one of the four major clades of placental mammals. Sengis currently consist of twenty extant species, all of which are endemic to the African continent. They can be separated in two families, the soft-furred sengis (Macroscelididae) and the giant sengis (Rhynchocyonidae). While giant sengis can be exclusively found in forest habitats, the different soft-furred sengi species dwell in a broad range of habitats, from tropical rain-forests to rocky deserts. Our knowledge on the evolutionary history of sengis is largely incomplete. The high level of superficial morphological resemblance among different sengi species (especially the soft-furred sengis) has for example led to misinterpretations of phylogenetic relationships, based on morphological characters. With the rise of DNA based taxonomic inferences, multiple new genera were defined and new species described. Yet, no full taxon molecular phylogeny exists, hampering the answering of basic taxonomic questions. This lack of knowledge can be to some extent attributed to the limited availability of fresh-tissue samples for DNA extraction. The broad African distribution, partly in political unstable regions and low population densities complicate contemporary sampling approaches. Furthermore, the DNA information available usually covers only short stretches of the mitochondrial genome and thus a single genetic locus with limited informational content. Developments in DNA extraction and library protocols nowadays offer the opportunity to access DNA from museum specimens, collected over the past centuries and stored in natural history museums throughout the world. Thus, the difficulties in fresh-sample acquisition for molecular biological studies can be overcome by the application of museomics, the research field which emerged from those laboratory developments. This thesis uses fresh-tissue samples as well as a vast collection museum specimens to investigate multiple aspects about the macroscelidean evolutionary history. Chapter 4 of this thesis focuses on the phylogenetic relationships of all currently known sengi species. By accessing DNA information from museum specimens in combination of fresh tissue samples and publicly available genetic resources it produces the first full taxon molecular phylogeny of sengis. It confirms the monophyly of the genus Elephantulus and discovers multiple deeply divergent lineages within different species, highlighting the need for species specific approaches. The study furthermore focuses on the evolutionary time frame of sengis by evaluating the impact of commonly varied parameters on tree dating. The results of the study show, that the mitochondrial information used in previous studies to temporal calibrate the Macroscelidean phylogeny led to an overestimation of node ages within sengis. Especially soft-furred sengis are thus much younger than previously assumed. The refined knowledge of nodes ages within sengis offer the opportunity to link e.g. speciation events to environmental changes. Chapter 5 focuses on the genus Petrodromus with its single representative Petrodromus tetradactylus. It again exploits the opportunities of museomics and gathers a comprehensive, multi-locus genetic dataset of P. tetradactylus individuals, distributed across most the known range of this species. It reveals multiple deeply divergent lineages within Petrodromus, whereby some could possibly be associated to previously described sub-species, at least one was formerly unknown. It underscores the necessity for a revision of the genus Petrodromus through the integration of both molecular and morphological evidence. The study, furthermore identifies changing forest distributions through climatic oscillations as main factor shaping the genetic structure of Petrodromus. Chapter 6 uses fresh tissue samples to extent the genomic resources of sengis by thirteen new nuclear genomes, of which two were de-novo assembled. An extensive dataset of more than 8000 protein coding one-to-one orthologs allows to further refine and confirm the temporal time frame of sengi evolution found in Chapter 4. This study moreover investigates the role of gene-flow and incomplete lineage sorting (ILS) in sengi evolution. In addition it identifies clade specific genes of possible outstanding evolutionary importance and links them to potential phenotypic traits affected. A closer investigation of olfactory receptor proteins reveals clade specific differences. A comparison of the demographic past of sengis to other small African mammals does not reveal a sengi specific pattern.}, language = {en} } @phdthesis{Rogge2024, author = {Rogge, Franziska}, title = {Multiprofessionelle Kooperation an inklusiven Schulen im Bundesland Brandenburg: Vorkommen, Profile, Auswirkungen}, doi = {10.25932/publishup-63919}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-639190}, school = {Universit{\"a}t Potsdam}, pages = {202}, year = {2024}, abstract = {Die Zusammenarbeit zwischen Lehr- und anderen Fachkr{\"a}ften stellt in Modellen inklusiver Schul- und Unterrichtsentwicklung sowie Schuleffektivit{\"a}t ein wichtiges Element dar. Wenngleich Kooperation als bedeutsam postuliert wird, so belegen Studien, dass diese bisher {\"u}berwiegend in autonomieerhaltenden Formen praktiziert wird. Als entwicklungsf{\"o}rderlich gelten jedoch v.a. komplexere Formen der Zusammenarbeit. Vor dem Hintergrund inklusiver Bildung und dem Anspruch einer bestm{\"o}glichen individuellen Entwicklung der Sch{\"u}ler*innen stellt die Zusammenarbeit von Lehr- und Fachkr{\"a}ften folglich ein sehr bedeutsames Thema dar. Es ist zu hinterfragen, wie sich die Zusammenarbeit zwischen Lehr- und Fachkr{\"a}ften im Primar- wie Sekundarstufenbereich an inklusiven Schulen gestaltet, welche Faktoren diese beeinflussen und welche Relevanz die unterschiedlichen Formen der Zusammenarbeit im Prozess inklusiver Schulentwicklung einnehmen. Bestehende Forschungsdesiderata aufgrei-fend, fokussiert die vorliegende Dissertation auf die realisierte Zusammenarbeit von Lehr- und Fachkr{\"a}ften im Primar- und Sekundarstufenbereich inklusiver Schulen, am Beispiel des Landes Brandenburg. Neben den realisierten Formen der Zusammenarbeit, stehen insbesondere die Identifikation von Kooperationsmustern von Lehr- und Fachkr{\"a}ften sowie von Schulen, und deren Zusammenh{\"a}nge mit der Leistungsentwicklung von Sch{\"u}ler*innen im Kern des Forschungsinteresses. Die vorliegende Dissertation bearbeitet insgesamt sechs Forschungsfragen, welche in drei Teilstudien adressiert werden: Zun{\"a}chst werden mittels deskriptiver Analysen sowie Mehrebenenmodellierungen die Ausgangslage multiprofessioneller Kooperation (erste Forschungsfrage) sowie deren Rahmenbedingungen (zweite Forschungsfrage) im Primar- wie Sekundarstufenbereich erfasst (Teilstudie 1). Lehr- und Fachkr{\"a}fte kooperierten {\"u}berwiegend in autonomieerhaltenden, austauschbasierten Formen. Weiterhin zeigte sich, dass insbesondere die individuelle Offenheit zur Zusammenarbeit sowie die subjektiv wahrgenommene Unterst{\"u}tzung durch die Schulleitung bedeutsame Faktoren f{\"u}r die Realisierung multiprofessioneller Kooperation darstellten. Die Fragestellungen drei und vier befassen sich mit der Identifikation von Mustern im Kooperationsverhalten (Teilstudie 2). Zum einen geht es hierbei um personenbezogene Profile von Lehr- und Fachkr{\"a}ften (dritte Forschungsfrage), zum anderen um schulbezogene Profile (vierte Forschungsfrage), welche mittels des personenzentrierten Ansatzes der latenten Profilanalysen unter Ber{\"u}cksichtigung der Mehrebenenstruktur identifiziert werden. Hinsichtlich des individuellen Kooperationsverhaltens konnten vier Profile eruiert werden, bzgl. des schulspezifischen Kooperationsverhaltens drei. Die Mehrheit der Lehr- und Fachkr{\"a}fte konnte im „regularly"-Profil verortet werden, d.h. nach eigener Einsch{\"a}tzung kooperierten diese {\"u}berdurchschnittlich h{\"a}ufig im Austausch miteinander und arbeitsteilig, aber auch regelm{\"a}ßig kokonstruktiv. Auf Schulebene zeigte sich, dass etwa jede zweite inklusive Schule im Land Brandenburg {\"u}ber eine hoch ausgepr{\"a}gte Kooperationskultur verf{\"u}gte. Im Fokus der Teilstudie 3 wird den Fragen nachgegangen, in welchem Zusammenhang die schulspezifischen Kooperationskulturen mit der Leistungsentwicklung von Sch{\"u}ler*innen in der Primar- wie Sekundarstufe steht. Mittels autoregressiver Mehrebenenanalysen wird einerseits der Zusammenhang mit der Leistungsentwicklung aller Sch{\"u}ler*innen (f{\"u}nfte Forschungsfrage) untersucht, sowie spezifisch auf die Entwicklung von Sch{\"u}ler*innen mit und ohne sonderp{\"a}dagogischem F{\"o}rderbedarf (sechste Forschungsfrage) fokussiert. Ein zentrales Ergebnis war hierbei, dass Sch{\"u}ler*innen mit sonderp{\"a}dagogischem F{\"o}rderbedarf in der Primar- wie Sekundarstufe in ihrer Leistungsentwicklung am st{\"a}rksten profitierten, wenn sie an Schulen lernten, an denen sich die Lehr- und Fachkr{\"a}fte sehr regelm{\"a}ßig {\"u}ber Lernst{\"a}nde der Sch{\"u}ler*innen austauschten (Austausch), Arbeitspakete f{\"u}r differenzierte Lernangebote erarbeiteten und verteilten (Arbeitsteilung) und dar{\"u}ber hinaus gelegentlich gemeinsam Probleml{\"o}sungen entwickelten (Kokonstruktion). Die Ergebnisse werden vor dem Hintergrund der postulierten Relevanz multiprofessioneller Kooperation f{\"u}r inklusive Schul- und Unterrichtsentwicklungsprozesse eingeordnet und diskutiert.

Cultural difference was expressed in terms of temporal distance while temporal distance was attributed to spatial remoteness.

Clean-up certificates bundle the permission to emit CO2 with the obligation for its removal. We show that demand for such certificates is determined by cost-saving technological progress, the discount rate and the length of the compliance period. Introducing extra clean-up certificates into an existing ETS reduces near-term carbon prices and mitigation efforts. In contrast, substituting ETS allowances with clean-up certificates reduces cumulative emissions without depressing carbon prices or mitigation in the near term. We calibrate our model to the EU ETS and identify reforms where simultaneously (i) ambition levels rise, (ii) climate damages fall, (iii) revenues from carbon prices rise and (iv) carbon prices and aggregate mitigation cost fall. For reducing climate damages, roughly half of the issued clean-up certificates should replace conventional ETS allowances.

Investigating their historical dynamics can enhance our understanding of how they might respond to unprecedented future environmental shifts. With Arctic lakes currently under substantial pressure from climate change, lessons from the past can guide our understanding of potential disruptions to these lakes. However, individual lake systems are multifaceted and complex. Traditional isolated lake studies often fail to provide a global perspective because localized nuances—like individual lake parameters, catchment areas, and lake histories—can overshadow broader conclusions. In light of these complexities, a more nuanced approach is essential to analyze lake systems in a global context. A key to addressing this challenge lies in the data-driven analysis of sedimentological records from various northern lake systems. This dissertation emphasizes lake systems in the northern Eurasian region, particularly in Russia (n=59). For this doctoral thesis, we collected sedimentological data from various sources, which required a standardized framework for further analysis. Therefore, we designed a conceptual model for integrating and standardizing heterogeneous multi-proxy data into a relational database management system (PostgreSQL). Creating a database from the collected data enabled comparative numerical analyses between spatially separated lakes as well as between different proxies. When analyzing numerous lakes, establishing a common frame of reference was crucial. We achieved this by converting proxy values from depth dependency to age dependency. This required consistent age calculations across all lakes and proxies using one age-depth modeling software. Recognizing the broader implications and potential pitfalls of this, we developed the LANDO approach ("Linked Age and Depth Modelling"). LANDO is an innovative integration of multiple age-depth modeling software into a singular, cohesive platform (Jupyter Notebook). Beyond its ability to aggregate data from five renowned age-depth modeling software, LANDO uniquely empowers users to filter out implausible model outcomes using robust geoscientific data. Our method is not only novel but also significantly enhances the accuracy and reliability of lake analyses. Considering the preceding steps, this doctoral thesis further examines the relationship between carbon in sediments and temperature over the last 21,000 years. Initially, we hypothesized a positive correlation between carbon accumulation in lakes and modelled paleotemperature. Our homogenized dataset from heterogeneous lakes confirmed this association, even if the highest temperatures throughout our observation period do not correlate with the highest carbon values. We assume that rapid warming events contribute more to high accumulation, while sustained warming leads to carbon outgassing. Considering the current high concentration of carbon in the atmosphere and rising temperatures, ongoing climate change could cause northern lake systems to contribute to a further increase in atmospheric carbon (positive feedback loop). While our findings underscore the reliability of both our standardized data and the LANDO method, expanding our dataset might offer even greater assurance in our conclusions.}, language = {en} } @article{Kay2024, author = {Kay, Alex James}, title = {The extermination of Red Army soldiers in German captivity, 1941-1945}, series = {Journal of Slavic Military Studies}, volume = {37}, journal = {Journal of Slavic Military Studies}, number = {1}, publisher = {Taylor \& Francis}, address = {London}, issn = {1556-3006}, doi = {10.1080/13518046.2024.2340839}, pages = {80 -- 104}, year = {2024}, abstract = {Captive Red Army soldiers made up the majority of victims of Nazi Germany's starvation policy against Soviet civilians and other non-combatants and thus constituted the largest single victim group of the German war of annihilation against the Soviet Union. Indeed, Soviet prisoners of war were the largest victim group of all National Socialist annihilation policies after the European Jews. Before the launch of Operation Barbarossa, it was clear to the Wehrmacht planning departments on exactly what scale they could expect to capture Soviet troops. Yet, they neglected to make the necessary preparations for feeding and sheltering the captured soldiers, who were viewed by the economic staffs and the military leadership alike as direct competitors of German troops and the German home front for precious food supplies. The number of extra mouths to feed was incompatible with German war aims. The obvious limitations on their freedom of movement and the relative ease with which large numbers could be segregated and their rations controlled were crucial factors in the death of over 3 million Soviet POWs, the vast majority directly or indirectly as a result of deliberate policies of neglect, undernourishment, and starvation while in the 'care' of the Wehrmacht. The most reliable figures for the mortality of Soviet POWs in German captivity reveal that up to 3.3 million died from a total of just over 5.7 million captured between June 1941 and February 1945 — a proportion of almost 58 percent. Of these, 2 million were already dead by the beginning of February 1942. In English, there is still neither a single monograph nor a single edited volume dedicated to the subject. This article now provides the first detailed stand-alone synthesis in that language addressing the whole period from 1941 to 1945.}, language = {en} } @inproceedings{AbendrothBenderGronau2024, author = {Abendroth, Adrian and Bender, Benedict and Gronau, Norbert}, title = {The evolution of original ERP customization}, series = {Proceedings of the 26th International Conference on Enterprise Information Systems}, volume = {1}, booktitle = {Proceedings of the 26th International Conference on Enterprise Information Systems}, publisher = {SCITEPRESS - Science and Technology Publications}, address = {Set{\´u}bal}, isbn = {978-989-758-692-7}, issn = {2184-4992}, doi = {10.5220/0012305500003690}, pages = {17 -- 27}, year = {2024}, abstract = {Enterprise Resource Planning (ERP) system customization is often necessary because companies have unique processes that provide their competitive advantage. Despite new technological advances such as cloud computing or model-driven development, technical ERP customization options are either outdated or ambiguously formulated in the scientific literature. Using a systematic literature review (SLR) that analyzes 137 definitions from 26 papers, the result is an analysis and aggregation of technical customization types by providing clearance and aligning with future organizational needs. The results show a shift from ERP code modification in on-premises systems to interface and integration customization in cloud ERP systems, as well as emerging technological opportunities as a way for customers and key users to perform system customization. The study contributes by providing a clear understanding of given customization types and assisting ERP users and vendors in making customization decisions.}, language = {en} }
