This study aims to alleviate this puzzle by investigating how managers and employees in German public sector organisations make sense of agile as a spreading management fashion in the form of narratives. This is important because narratives function as innovation carriers that ultimately influence the manifestations of the concept in organisations. Based on a multi-case study of 31 interviews and 24 responses to a qualitative online survey conducted in 2021 and 2022, we provide insights into what public sector managers, employees and consultants understand (and, more importantly, do not understand) as agile and how they weave it into their existing reality of bureaucratic organisations. We uncover three meta-narratives of agile government, which we label 'renew', 'complement' and 'integrate'. In particular, the meta-narratives differ in their positioning of how agile interacts with the characteristics of bureaucratic organisations. Importantly, we also show that agile as a management fad serves as a projection surface for what actors want from a modern and digital organisation. Thus, the vocabulary of agile government within the narratives is inherently linked to other diffusing phenomena such as new work or digitalisation.}, language = {en} } @phdthesis{Pfalz2024, author = {Pfalz, Gregor}, title = {Advancing knowledge of Arctic lake system dynamics: A data-driven perspective on spatiotemporal patterns}, doi = {10.25932/publishup-63655}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-636554}, school = {Universit{\"a}t Potsdam}, pages = {xiii, 136}, year = {2024}, abstract = {Ecosystems play a pivotal role in addressing climate change but are also highly susceptible to drastic environmental changes. 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} } @phdthesis{Richly2024, author = {Richly, Keven}, title = {Memory-efficient data management for spatio-temporal applications}, doi = {10.25932/publishup-63547}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-635473}, school = {Universit{\"a}t Potsdam}, pages = {xii, 181}, year = {2024}, abstract = {The wide distribution of location-acquisition technologies means that large volumes of spatio-temporal data are continuously being accumulated. 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} } @misc{Wiesmeier2024, type = {Master Thesis}, author = {Wiesmeier, Rebekka}, title = {Cultural conceptualisations relating to DEATH in Irish English from a diachronic perspective}, doi = {10.25932/publishup-63871}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-638719}, school = {Universit{\"a}t Potsdam}, pages = {104}, year = {2024}, abstract = {The present thesis looks at cultural conceptualisations in relation to DEATH in Irish English from a Cultural Linguistic perspective and puts a special focus on the diachronic development of these conceptualisations. For the study, a corpus consisting of 1,400 death notices from the Dublin-based national newspaper The Irish Times from 14 historical periods between 1859 and 2023 was compiled, resulting in a highly specialised 70,000-word corpus. First, the manual qualitative analysis of the death notices produced evidence for eight superordinate cultural conceptualisations surrounding DEATH, namely, in the order of their frequency THE DEAD ARE TO BE REMEMBERED OR REGRETTED, DEATH IS SOMETHING POSITIVE, DEATH IS REST, DEATH IS A JOURNEY, DYING IS THE BEGINNING OF ANOTHER LIFE, DEATH IS (NOT) A TABOO, DEATH IS GOD'S WILL, and DEATH IS THE END. These conceptualisations were derived from linguistic expressions in the death notices that have these conceptualisations as a cognitive basis. Second, the quantitative comparison of the individual conceptualisations detected diachronic variation, which is interconnected with historical and social developments in Ireland. The thesis, therefore, illustrates the applicability of Cultural Linguistics as an adequate method for diachronic studies interested in culturally determined developments of conceptualisations.}, language = {en} } @masterthesis{Schulz2024, type = {Bachelor Thesis}, author = {Schulz, Florian}, title = {Game Design im Kontext von Kunst und Kunstunterricht}, doi = {10.25932/publishup-64177}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-641773}, school = {Universit{\"a}t Potsdam}, pages = {50}, year = {2024}, abstract = {Im Kontext der zunehmenden Relevanz des Umgangs mit Digitalit{\"a}t im schulischen Unterricht und der daraus resultierenden Popularit{\"a}t von Gaming und Gamification als Lehrmethoden ist das Ziel dieser Arbeit, Game Design als konstruktivistische Herangehensweise an Computerspiele zu untersuchen.

First, we uncover a high rate of fully computationally reproducible results (over 85\%). Second, excluding minor issues like missing packages or broken pathways, we uncover coding errors for about 25\% of studies, with some studies containing multiple errors. Third, we test the robustness of the results to 5,511 re-analyses. We find a robustness reproducibility of about 70\%. Robustness reproducibility rates are relatively higher for re-analyses that introduce new data and lower for re-analyses that change the sample or the definition of the dependent variable.

With the continued global rise in forced displacement, not appearing welcoming to migrants has become a guiding principle for the asylum policy of many large receiving countries.

Werden Proteine nichtmenschlichen Ursprungs verwendet, kann es jedoch zu einer Immunreaktion kommen, sodass das Protein sehr schnell aus dem K{\"o}rper ausgeschieden oder abgebaut wird. Um die Zirkulationszeit im Blut signifikant zu verl{\"a}ngern, werden die Proteine mit synthetischen Polymeren modifiziert (Protein-Polymer-Konjugate). Die Proteine aller heute auf dem Markt erh{\"a}ltlichen Medikamente dieser Art tragen eine oder mehrere Polymerketten aus Poly(ethylenglycol) (PEG). Ein Nachteil der PEGylierung ist, dass viele Patienten bei regelm{\"a}ßiger Einnahme dieser Medikamente Antik{\"o}rper gegen PEG entwickeln, die den effizienzsteigernden Effekt der PEGylierung wieder aufheben. Ein weiterer Nachteil der PEGylierung ist die oftmals deutlich verringerte Aktivit{\"a}t der Konjugate im Vergleich zum nativen Protein. Der Grund daf{\"u}r ist die Herstellungsmethode der Konjugate, bei der meist die prim{\"a}ren Amine der Lysin-Seitenketten und der N-Terminus des Proteins genutzt werden. Da die meisten Proteine mehrere gut zug{\"a}ngliche Lysine aufweisen, werden oft unterschiedliche und teilweise mehrere Lysine mit PEG funktionalisiert, was zu einer Mischung an Regioisomeren f{\"u}hrt. Je nach Position der PEG-Kette kann das aktive Zentrum abgeschirmt oder die 3D-Struktur des Proteins ver{\"a}ndert werden, was zu einem teilweise drastischen Aktivit{\"a}tsabfall f{\"u}hrt. In dieser Arbeit wurde eine neuartige Methode zur Ligation von Makromolek{\"u}len untersucht. Die Verwendung eines Enzyms als Katalysator zur Verbindung zweier Makromolek{\"u}le ist bisher wenig untersucht und ineffizient. Als Enzym wurde Sortase A ausgew{\"a}hlt, eine gut untersuchte Ligase aus der Familie der Transpeptidasen, welche die Ligation zweier Peptide katalysieren kann. Ein Nachteil dieser Sortase-vermittelten Ligation ist, dass es sich um eine Gleichgewichtsreaktion handelt, wodurch hohe Ausbeuten schwierig zu erreichen sind. Im Rahmen dieser Dissertation wurden zwei zuvor entwickelte Methoden zur Verschiebung des Gleichgewichts ohne Einsatz eines großen {\"U}berschusses von einem Edukt f{\"u}r Makromolek{\"u}le {\"u}berpr{\"u}ft. Zur Durchf{\"u}hrung der Sortase-vermittelten Ligation werden zwei komplement{\"a}re Peptidsequenzen verwendet, die Erkennungssequenz und das Nukleophil. Um eine systematische Untersuchung durchf{\"u}hren zu k{\"o}nnen, wurden alle n{\"o}tigen Bausteine (Protein-Erkennungssequenz zur Reaktion mit Nukleophil-Polymer und Polymer-Erkennungssequenz mit Nukleophil-Protein) hergestellt. Als Polymerisationstechnik wurde die radikalische Polymerisation mit reversibler Deaktivierung (im Detail, Atom Transfer Radical Polymerization, ATRP und Reversible Addition-Fragmentation Chain Transfer, RAFT polymerization) gew{\"a}hlt, um eine enge Molmassenverteilung zu erreichen. Die Herstellung der Bausteine begann mit der Synthese der Peptide via automatisierter Festphasen-Peptidsynthese, um eine einfache {\"A}nderung der Peptidsequenz zu gew{\"a}hrleisten und um eine Modifizierung der Polymerkette nach der Polymerisation zu umgehen. Um die ben{\"o}tigte unterschiedliche Funktionalit{\"a}t der zwei Peptidsequenzen (freier C-Terminus bei der Erkennungssequenz bzw. freier N-Terminus bei dem Nukleophil) zu erreichen, wurden verschiedene Linker zwischen Harz und Peptid verwendet. Danach wurde der Ketten{\"u}bertr{\"a}ger (chain transfer agent, CTA) zur Kontrolle der Polymerisation mit dem auf dem Harz befindlichen Peptid gekoppelt. Die f{\"u}r die anschließende Polymerisation verwendeten Monomere basierten auf Acrylamiden und Acrylaten und wurden anhand ihrer Eignung als Alternativen zu PEG ausgew{\"a}hlt. Es wurde eine k{\"u}rzlich entwickelte Technik basierend auf der RAFT-Polymerisation (xanthate-supported photo-iniferter RAFT, XPI-RAFT) verwendet um eine Reihe an Peptid-Polymeren mit unterschiedlichen Molekulargewichten und engen Molekulargewichtsverteilungen herzustellen. Nach Entfernung der Schutzgruppen der Peptid-Seitenketten wurden die Peptid-Polymere zun{\"a}chst genutzt, um mittels Sortase-vermittelter Ligation zwei Polymerketten zu einem Blockcopolymer zu verbinden. Unter Verwendung von Ni2+-Ionen in Kombination mit einer Verl{\"a}ngerung der Erkennungssequenz um ein Histidin zur Unterdr{\"u}ckung der R{\"u}ckreaktion konnte ein maximaler Umsatz von 70 \% erreicht werden. Dabei zeigte sich ein oberes Limit von durchschnittlich 100 Wiederholungseinheiten; die Ligation von l{\"a}ngeren Polymeren war nicht erfolgreich. Danach wurden ein Modellprotein und ein Nanobody mit vielversprechenden medizinischen Eigenschaften mit den f{\"u}r die enzymkatalysierte Ligation ben{\"o}tigten Peptidsequenzen f{\"u}r die Kopplung mit den zuvor hergestellten Peptid-Polymeren verwendet. Dabei konnte bei Verwendung des Modellproteins keine Bildung von Protein-Polymer-Konjugaten beobachtet werden. Der Nanobody konnte dagegen C-terminal mit einem Polymer funktionalisiert werden. Dabei wurde eine {\"a}hnliche Limitierung in der Polymer-Kettenl{\"a}nge beobachtet wie zuvor. Die auf Ni-Ionen basierte Strategie zur Gleichgewichtsverschiebung hatte hier keinen ausschlaggebenden Effekt, w{\"a}hrend die Verwendung von einem {\"U}berschuss an Polymer zur vollst{\"a}ndigen Umsetzung des Edukt-Nanobody f{\"u}hrte. Die erhaltenen Daten aus diesem Projekt bilden eine gute Basis f{\"u}r weitere Forschung in dem vielversprechenden Feld der enzymkatalysierten Herstellung von Protein-Polymer-Konjugaten und Blockcopolymeren.

The age of genomics provides an opportunity to investigate evolution using whole nuclear genomes. Decreasing sequencing costs enable the recovery of multiple loci per genome, giving more power to single specimen analyses and providing higher resolution insights into species and populations that can help guide conservation efforts. This age of genomics has only recently begun for African antelopes. Many African bovids have a declining population trend and hence, are often endangered. Consequently, contemporary samples from the wild are often hard to collect. In these cases, ex situ samples from contemporary captive populations or in the form of archival or ancient DNA (aDNA) from historical museum or archaeological/paleontological specimens present a great research opportunity with the latter two even offering a window to information about the past. However, the recovery of aDNA is still considered challenging from regions with prevailing climatic conditions that are deemed adverse for DNA preservation like the African continent. This raises the question if DNA recovery from fossils as old as the early Holocene from these regions is possible. This thesis focuses on investigating the evolutionary history and genetic diversity of two species: the addax (Addax nasomaculatus) and the blue antelope (Hippotragus leucophaeus). The addax is critically endangered and might even already be extinct in the wild, while the blue antelope became extinct ~1800 AD, becoming the first extinct large African mammal species in historical times. Together, the addax and the blue antelope can inform us about current and past extinction events and the knowledge gained can help guide conservation efforts of threatened species. The three studies used ex situ samples and present the first nuclear whole genome data for both species. The addax study used historical museum specimens and a contemporary sample from a captive population. The two studies on the blue antelope used mainly historical museum specimens but also fossils, and resulted in the recovery of the oldest paleogenome from Africa at that time. The aim of the first study was to assess the genetic diversity and the evolutionary history of the addax. It found that the historical wild addax population showed only limited phylogeographic structuring, indicating that the addax was a highly mobile and panmictic population and suggesting that the current European captive population might be missing the majority of the historical mitochondrial diversity. It also found the nuclear and mitochondrial diversity in the addax to be rather low compared to other wild ungulate species. Suggestions on how to best save the remaining genetic diversity are presented. The European zoo population was shown to exhibit no or only minor levels of inbreeding, indicating good prospects for the restoration of the species in the wild. The trajectory of the addax's effective population size indicated a major bottleneck in the late Pleistocene and a low effective population size well before recent human impact led to the species being critically endangered today. The second study set out to investigate the identities of historical blue antelope specimens using aDNA techniques. Results showed that six out of ten investigated specimens were misidentified, demonstrating the blue antelope to be one of the scarcest mammal species in historical natural history collections, with almost no bone reference material. The preliminary analysis of the mitochondrial genomes suggested a low diversity and hence low population size at the time of the European colonization of southern Africa. Study three presents the results of the analyses of two blue antelope nuclear genomes, one ~200 years old and another dating to the early Holocene, 9,800-9,300 cal years BP. A fossil-calibrated phylogeny dated the divergence time of the three historically extant Hippotragus species to ~2.86 Ma and demonstrated the blue and the sable antelope (H. niger) to be sister species. In addition, ancient gene flow from the roan (H. equinus) into the blue antelope was detected. A comparison with the roan and the sable antelope indicated that the blue antelope had a much lower nuclear diversity, suggesting a low population size since at least the early Holocene. This concurs with findings from the fossil record that show a considerable decline in abundance after the Pleistocene-Holocene transition. Moreover, it suggests that the blue antelope persisted throughout the Holocene regardless of a low population size, indicating that human impact in the colonial era was a major factor in the blue antelope's extinction. This thesis uses aDNA analyses to provide deeper insights into the evolutionary history and genetic diversity of the addax and the blue antelope. Human impact likely was the main driver of extinction in the blue antelope, and is likely the main factor threatening the addax today. This thesis demonstrates the value of ex situ samples for science and conservation, and suggests to include genetic data for conservation assessments of species. It further demonstrates the beneficial use of aDNA for the taxonomic identification of historically important specimens in natural history collections. Finally, the successful retrieval of a paleogenome from the early Holocene of Africa using shotgun sequencing shows that DNA retrieval from samples of that age is possible from regions generally deemed unfavorable for DNA preservation, opening up new research opportunities. All three studies enhance our knowledge of African antelopes, contributing to the general understanding of African large mammal evolution and to the conservation of these and similarly threatened species.}, language = {en} } @phdthesis{Fischer2024, author = {Fischer, Florian}, title = {Hardy inequalities on graphs}, doi = {10.25932/publishup-64773}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-647730}, school = {Universit{\"a}t Potsdam}, pages = {vi, 160}, year = {2024}, abstract = {Die Dissertation befasst sich mit einer zentralen Ungleichung der nicht-linearen Potentialtheorie, der Hardy-Ungleichung.

Verb-final languages have a reputation for a high amount of word order variability. However, that reputation amounts to an urban myth due to a lack of systematic investigation. This thesis provides such a systematic investigation by presenting original data from several verb-final languages with a focus on four Uralic ones: Estonian, Udmurt, Meadow Mari, and South S{\´a}mi. As with every urban myth, there is a kernel of truth in that many unrelated verb-final languages share a particular kind of word order variability, A-scrambling, in which the fronted elements do not receive a special information-structural role, such as topic or contrastive focus. That word order variability goes hand in hand with placing focussed phrases further to the right in the position directly in front of the verb. Variations on this pattern are exemplified by Uyghur, Standard Dargwa, Eastern Armenian, and three of the Uralic languages, Estonian, Udmurt, and Meadow Mari. So far for the kernel of truth, but the fourth Uralic language, South S{\´a}mi, is comparably rigid and does not feature this particular kind of word order variability. Further such comparably rigid, non-scrambling verb-final languages are Dutch, Afrikaans, Amharic, and Korean. In contrast to scrambling languages, non-scrambling languages feature obligatory subject movement, causing word order rigidity next to other typical EPP effects. The EPP is a defining feature of South S{\´a}mi clause structure in general. South S{\´a}mi exhibits a one-of-a-kind alternation between SOV and SAuxOV order that is captured by the assumption of the EPP and obligatory movement of auxiliaries but not lexical verbs. Other languages that allow for SAuxOV order either lack an alternation because the auxiliary is obligatorily present (Macro-Sudan SAuxOVX languages), or feature an alternation between SVO and SAuxOV (Kru languages; V2 with underlying OV as a fringe case). In the SVO-SAuxOV languages, both auxiliaries and lexical verbs move. Hence, South S{\´a}mi shows that the textbook difference between the VO languages English and French, whether verb movement is restricted to auxiliaries, also extends to OV languages. SAuxOV languages are an outlier among OV languages in general but are united by the presence of the EPP. Word order variability is not restricted to the preverbal field in verb-final languages, as most of them feature postverbal elements (PVE). PVE challenge the notion of verb-finality in a language. Strictly verb-final languages without any clause-internal PVE are rare. This thesis charts the first structural and descriptive typology of PVE. Verb-final languages vary in the categories they allow as PVE. Allowing for non-oblique PVE is a pivotal threshold: when non-oblique PVE are allowed, PVE can be used for information-structural effects. Many areally and genetically unrelated languages only allow for given PVE but differ in whether the PVE are contrastive. In those languages, verb-finality is not at stake since verb-medial orders are marked. In contrast, the Uralic languages Estonian and Udmurt allow for any PVE, including information focus. Verb-medial orders can be used in the same contexts as verb-final orders without semantic and pragmatic differences. As such, verb placement is subject to actual free variation. The underlying verb-finality of Estonian and Udmurt can only be inferred from a range of diagnostics indicating optional verb movement in both languages. In general, it is not possible to account for PVE with a uniform analysis: rightwards merge, leftward verb movement, and rightwards phrasal movement are required to capture the cross- and intralinguistic variation. Knowing that a language is verb-final does not allow one to draw conclusions about word order variability in that language. There are patterns of homogeneity, such as the word order variability driven by directly preverbal focus and the givenness of postverbal elements, but those are not brought about by verb-finality alone. Preverbal word order variability is restricted by the more abstract property of obligatory subject movement, whereas the determinant of postverbal word order variability has to be determined in the future.}, language = {en} } @book{CurielMartinez2024, author = {Curiel Mart{\´i}nez, Geishel}, title = {Rumbo a Venecia}, editor = {Ette, Ottmar}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-558-3}, issn = {2629-2548}, doi = {10.25932/publishup-58696}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-586964}, publisher = {Universit{\"a}t Potsdam}, pages = {212}, year = {2024}, abstract = {Esta investigaci{\´o}n explora la representaci{\´o}n de viajes a Venecia en la literatura latinoamericana y de lengua alemana del siglo XX.

Importantly, the human brain inherits from evolution a predisposition to map cardinality onto space, as revealed by the presence of spatial-numerical associations (SNAs) in humans and animals. Here, the mapping of cardinal information onto physical space is addressed as a hallmark signature characterizing numerical cognition. According to traditional approaches, cognition is defined as complex forms of internal information processing, taking place in the brain (cognitive processor). On the contrary, embodied cognition approaches define cognition as functionally linked to perception and action, in the continuous interaction between a biological body and its physical and sociocultural environment. Embracing the principles of the embodied cognition perspective, I conducted four novel studies designed to unveil how SNAs originate, develop, and adapt, depending on characteristics of the organism, the context, and their interaction. I structured my doctoral thesis in three levels. At the grounded level (Study 1), I unfold the biological foundations underlying the tendency to map cardinal information across space; at the embodied level (Study 2), I reveal the impact of atypical motor development on the construction of SNAs; at the situated level (Study 3), I document the joint influence of visuospatial attention and task properties on SNAs. Furthermore, I experimentally investigate the presence of associations between physical and numerical distance, another numerical property fundamental for the development of efficient mathematical minds (Study 4). In Study 1, I present the Brain's Asymmetric Frequency Tuning hypothesis that relies on hemispheric asymmetries for processing spatial frequencies, a low-level visual feature that the (in)vertebrate brain extracts from any visual scene to create a coherent percept of the world. Computational analyses of the power spectra of the original stimuli used to document the presence of SNAs in human newborns and animals, support the brain's asymmetric frequency tuning as a theoretical account and as an evolutionarily inherited mechanism scaffolding the universal and innate tendency to represent cardinality across horizontal space. In Study 2, I explore SNAs in children with rare genetic neuromuscular diseases: spinal muscular atrophy (SMA) and Duchenne muscular dystrophy (DMD). SMA children never accomplish independent motoric exploration of their environment; in contrast, DMD children do explore but later lose this ability. The different SNAs reported by the two groups support the critical role of early sensorimotor experiences in the spatial representation of cardinality. In Study 3, I directly compare the effects of overt attentional orientation during explicit and implicit processing of numerical magnitude. First, the different effects of attentional orienting based on the type of assessment support different mechanisms underlying SNAs during explicit and implicit assessment of numerical magnitude. Secondly, the impact of vertical shifts of attention on the processing of numerical distance sheds light on the correspondence between numerical distance and peri-personal distance. In Study 4, I document the presence of different SNAs, driven by numerical magnitude and numerical distance, by employing different response mappings (left vs. right and near vs. distant). In the field of numerical cognition, the four studies included in the present thesis contribute to unveiling how the characteristics of the organism and the environment influence the emergence, the development, and the flexibility of our attitude to represent cardinal information across space, thus supporting the predictions of the embodied cognition approach. Furthermore, they inform a taxonomy of body-centred factors (biological properties of the brain and sensorimotor system) modulating the spatial representation of cardinality throughout the course of life, at the grounded, embodied, and situated levels. If the awareness for different variables influencing SNAs over the course of life is important, it is equally important to consider the organism as a whole in its sensorimotor interaction with the world. Inspired by my doctoral research, here I propose a holistic perspective that considers the role of evolution, embodiment, and environment in the association of cardinal information with directional space. The new perspective advances the current approaches to SNAs, both at the conceptual and at the methodological levels. Unveiling how the mental representation of cardinality emerges, develops, and adapts is necessary to shape efficient mathematical minds and achieve economic productivity, technological progress, and a higher quality of life.}, language = {en} } @phdthesis{Aral2024, author = {Aral, Tuğ{\c{c}}e}, title = {Socialization and development of racial knowledge among youth in inequitable societies}, doi = {10.25932/publishup-64855}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-648559}, school = {Universit{\"a}t Potsdam}, pages = {175}, year = {2024}, abstract = {Background: Societies worldwide have become more diverse yet continue to be inequitable. Understanding how youth growing up in these societies are socialized and consequently develop racial knowledge has important implications not only for their well-being but also for building more just societies. Importantly, there is a lack of research on these topics in Germany and Europe in general. Aim and Method: The overarching aim of the dissertation is to investigate 1) where and how ethnic-racial socialization (ERS) happens in inequitable societies and 2) how it relates to youth's development of racial knowledge, which comprises racial beliefs (e.g., prejudice, attitudes), behaviors (e.g., actions preserving or disrupting inequities), and identities (e.g., inclusive, cultural). Guided by developmental, cultural, and ecological theories of socialization and development, I first explored how family, as a crucial socialization context, contributes to the preservation or disruption of racism and xenophobia in inequitable societies through its influence on children's racial beliefs and behaviors. I conducted a literature review and developed a conceptual model bridging research on ethnic-racial socialization and intergroup relations (Study 1). After documenting the lack of research on socialization and development of racial knowledge within and beyond family contexts outside of the U.S., I conducted a qualitative study to explore ERS in Germany through the lens of racially marginalized youth (Study 2). Then, I conducted two quantitative studies to explore the separate and interacting relations of multiple (i.e., family, school) socialization contexts for the development of racial beliefs and behaviors (Study 3), and identities (Studies 3, 4) in Germany. Participants of Study 2 were 26 young adults (aged between 19 and 32) of Turkish, Kurdish, East, and Southeast Asian heritage living across different cities in Germany. Study 3 was conducted with 503 eighth graders of immigrant and non-immigrant descent (Mage = 13.67) in Berlin, Study 4 included 311 early to mid-adolescents of immigrant descent (Mage= 13.85) in North Rhine-Westphalia with diverse cultural backgrounds. Results and Conclusion: The findings revealed that privileged or marginalized positions of families in relation to their ethnic-racial and religious background in society entail differential experiences and thus are an important determining factor for the content/process of socialization and development of youth's racial knowledge. Until recently, ERS research mostly focused on investigating how racially marginalized families have been the sources of support for their children in resisting racism and how racially privileged families contribute to transmission of information upholding racism (Study 1). ERS for racially marginalized youth in Germany centered heritage culture, discrimination, and resistance strategies to racism, yet resistance strategies transmitted to youth mostly help to survive racism (e.g., working hard) by upholding it instead of liberating themselves from racism by disrupting it (e.g., self-advocacy, Study 2). Furthermore, when families and schools foster heritage and intercultural learning, both contexts may separately promote stronger identification with heritage culture and German identities, and more prosocial intentions towards disadvantaged groups (i.e., refugees) among youth (Studies 3, 4). However, equal treatment in the school context led to mixed results: equal treatment was either unrelated to inclusive identity, or positively related to German and negatively related to heritage culture identities (Studies 3, 4). Additionally, youth receiving messages highlighting strained and preferential intergroup relations at home while attending schools promoting assimilation may develop a stronger heritage culture identity (Study 4). In conclusion, ERS happened across various social contexts (i.e., family, community centers, school, neighborhood, peer). ERS promoting heritage and intercultural learning, at least in one social context (family or school), might foster youth's racial knowledge manifesting in stronger belonging to multiple cultures and in prosocial intentions toward disadvantaged groups. However, there is a need for ERS targeting increasing awareness of discrimination across social contexts of youth and teaching youth resistance strategies for liberation from racism.}, language = {en} }
