Their functionalities allow users to connect and interact with others and weave complex social networks in which social information is continuously disseminated between users. Besides the social value SNSs are generating, they likewise attract companies and allow for new forms of marketing, thereby creating considerable economic value alike. However, as SNSs grew in popularity, so did concerns about the impact of their use on social interactions in general and the well-being of individual users in particular. While existing scientific evidence points to both risk as well as benefits of SNS use, research still lacks a profound understanding of which aspects of SNSs enable an impact on well-being and which psychological processes on the part of the users underly and explain this relationship. Therefore, this thesis is dedicated to an in-depth exploration of the relationship between SNS use and well-being and aims to answer how SNS use can impact well-being. Primarily, it focuses on the unique technological features that characterize SNSs and enable potential well- being alterations and on specific psychological processes on the part of the users, underlying and explaining the relationship. For this purpose, the thesis first introduces the concept of well- being. It continues by presenting SNSs' unique technological features, divided into specifics of the content disseminated on SNSs and the network structure of SNSs. Further, the thesis introduces three classes of psychological processes assumed most relevant for the relationship between SNSs and well-being: other-focused, self-focused, and contrastive processes.. It is assumed that the course and quality of these common processes change in the SNS context and that a complex interplay between the unique features of SNSs and these processes determines how SNSs may ultimately affect users' well-being - both in positive and negative ways. The dissertation comprises seven research articles, each of which focusses on a particular set of SNS characteristics, their interplay with one or more of the proposed psychological processes, and ultimately the resulting effects on user well-being or its key resilience and risk factors. The seven articles investigate this relationship using different methodological approaches. Three articles are based on either systematic or narrative literature reviews, one applies an empirical cross-sectional research design, and three articles present an experimental investigation. Thematically, two articles revolve around SNS use's effect on self-esteem. Three articles examine the specific role of the emotion of envy and its potential to establish and perpetuate a well-being-damaging social climate on SNSs. The two last articles of this thesis revolve around the established assumption that active and passive SNS use, as different modalities of SNS use, cause differential effects on users' well-being due to the involvement of different psychological processes. The results of this thesis illustrate different ways how SNSs can affect users' well-being. The results suggest that especially contrastive processes play a decisive role in explaining potential well-being risks for SNS users. Their interplay with certain SNS features seems to foster upward social comparisons and feelings of envy, potentially leading to a complex set of deleterious effects on users' well-being. At the same time, the findings illuminate ways in which SNSs can benefit users and their self-esteem - especially when SNS use promotes self- focused and social-feedback-based other-focused processes. The thesis and their findings illustrate that the relationship between SNSs and well-being is complex. Therefore, a nuanced perspective, taking into consideration both the technological uniqueness of SNSs and the psychological processes they are enabling, is crucial to understand how these technologies affect their users in good and potentially harmful ways. On the one hand, the gathered insights contribute to research, providing novel insights into the complex relationship between SNS use and well-being. On the other hand, the results enable a focused and action-oriented derivation of recommendations for stakeholders such as individual users, policymakers, and platform providers. The findings of this thesis can help them to better combat SNS-related risks and ultimately ensure a healthy and sustainable environment for users - and thus also the economic values of SNSs - in the long term.}, language = {en} } @phdthesis{Esfahani2022, author = {Esfahani, Reza Dokht Dolatabadi}, title = {Time-dependent monitoring of near-surface and ground motion modelling: developing new data processing approaches based on Music Information Retrieval (MIR) strategies}, doi = {10.25932/publishup-56767}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-567671}, school = {Universit{\"a}t Potsdam}, pages = {xiv, 107}, year = {2022}, abstract = {Seismology, like many scientific fields, e.g., music information retrieval and speech signal pro- cessing, is experiencing exponential growth in the amount of data acquired by modern seismo- logical networks. In this thesis, I take advantage of the opportunities offered by "big data" and by the methods developed in the areas of music information retrieval and machine learning to predict better the ground motion generated by earthquakes and to study the properties of the surface layers of the Earth. In order to better predict seismic ground motions, I propose two approaches based on unsupervised deep learning methods, an autoencoder network and Generative Adversarial Networks. The autoencoder technique explores a massive amount of ground motion data, evaluates the required parameters, and generates synthetic ground motion data in the Fourier amplitude spectra (FAS) domain. This method is tested on two synthetic datasets and one real dataset. The application on the real dataset shows that the substantial information contained within the FAS data can be encoded to a four to the five-dimensional manifold. Consequently, only a few independent parameters are required for efficient ground motion prediction. I also propose a method based on Conditional Generative Adversarial Networks (CGAN) for simulating ground motion records in the time-frequency and time domains. CGAN generates the time-frequency domains based on the parameters: magnitude, distance, and shear wave velocities to 30 m depth (VS30). After generating the amplitude of the time-frequency domains using the CGAN model, instead of classical conventional methods that assume the amplitude spectra with a random phase spectrum, the phase of the time-frequency domains is recovered by minimizing the observed and reconstructed spectrograms. In the second part of this dissertation, I propose two methods for the monitoring and characterization of near-surface materials and site effect analyses. I implement an autocorrelation function and an interferometry method to monitor the velocity changes of near-surface materials resulting from the Kumamoto earthquake sequence (Japan, 2016). The observed seismic velocity changes during the strong shaking are due to the non-linear response of the near-surface materials. The results show that the velocity changes lasted for about two months after the Kumamoto mainshock. Furthermore, I used the velocity changes to evaluate the in-situ strain-stress relationship. I also propose a method for assessing the site proxy "VS30" using non-invasive analysis. In the proposed method, a dispersion curve of surface waves is inverted to estimate the shear wave velocity of the subsurface. This method is based on the Dix-like linear operators, which relate the shear wave velocity to the phase velocity. The proposed method is fast, efficient, and stable. All of the methods presented in this work can be used for processing "big data" in seismology and for the analysis of weak and strong ground motion data, to predict ground shaking, and to analyze site responses by considering potential time dependencies and nonlinearities.}, language = {en} } @phdthesis{Mahto2022, author = {Mahto, Harendra}, title = {In vitro analysis of Early Starvation 1 (ESV1) and Like Early Starvation 1 (LESV) on starch degradation with focus on glucan, water dikinase (GWD) and phosphoglucan, water dikinase (PWD)}, pages = {167}, year = {2022}, abstract = {Starch is an insoluble polyglucan, comprises of two polymers, namely, the branched α-1,4: α-1,6-D-glucan amylopectin and the almost unbranched α-1,4-D-glucan amylose. The growth of all plants is directly dependent on the accumulation of transitory starch during the daytime when photosynthesis takes place and subsequently starch degradation during the night. Starch phosphorylation takes place by starch-related dikinases called α-glucan, water dikinase (GWD), and phosphoglucan, water dikinase (PWD), and is a very important step in starch degradation. The biochemical mechanisms of phosphorylation of starch are not properly understood. Recent studies have found that there are two starch binding proteins namely, Early Starvation1 (ESV1) and Like Early Starvation1 (LESV), which play an important role in starch metabolism. It has been shown that ESV1 and LESV proteins affect the starch phosphorylation activity of GWD and PWD enzymes, which control the rate of degradation of starch granules. In this thesis, various in vitro assays were performed to identify and understand the mechanism of recombinant proteins; ESV1 and LESV on the starch degradation. The starch degradation was performed by phosphorylation enzymes, GWD and PWD separately. In various enzymatic assays, the influence of the ESV1 and LESV on the actions of GWD and PWD on the surfaces of different native starch granules were analysed. Furthermore, ESV1 and LESV have specifically shown influences on the phosphorylation activities of GWD and PWD on the starch granule surfaces in an antagonistic pattern in such a way that, the GWD mediated phosphorylation were significantly reduced while PWD mediated phosphorylation were significantly increased respectively. In another set of experiments, ISA and BAM hydrolyzing enzymes were used to alter the structure of starch, and then determine the effect of both dikinases mediated phosphorylation in the presence of ESV1 and LESV on the altered starch granules surfaces. In these results, significant decreases in both GWD and PWD mediated phosphorylation were observed in all the treatments containing either ESV1 or LESV proteins only or both ESV1 and LESV. It was also found that LESV preferentially binds to both amylose and amylopectin, while ESV1 binds to highly ordered glucans such as maltodextrins and amylopectin, which are crystalline in structure. Both ESV1 or LESV proteins either individually or in combination have shown influence on the activity of GWD and PWD phosphate incorporation into the starch granules via reduction even though at different percentages depending on the sources of starch, therefore it is difficult to distinguish the specific function between them. The biochemical studies have shown that protein-glucan interaction specifically between ESV1 or LESV or in combination with different species of starch granules has very strong surface binding, or it might be possible that both the proteins not only bind to the surface of the starch granules but also have entered deep inside the glucan structure of the starch granules. However, the results also revealed that ESV1 and LESV did not alter the autophosphorylation of the dikinases. Also, the chain length distribution pattern of the released glucan chains after treatment of starch with ISA enzyme was evaluated with respect to the degree of polymerization (DP) of the different starch granules. Capillary electrophoresis was employed to study the effect of LESV and ESV1 on the chain length distribution. In summary, this study confirms that ESV1 and LESV play an important role in organizing and regulating the starch metabolism process. In the later half, studies were performed to monitor whether the metabolism of carbohydrates and partitioning, contribute to the higher salt tolerance of the facultative halophyte Hordeum marinum when compared to glycophyte Hordeum vulgare. Seedlings with the same size from both species were hydroponically grown at 0, 150, and 300 mM of NaCl for 3 weeks. H. marinum maintained a high relative growth rate, which was found concomitant in higher aptitude plants to maintain efficient shoot tissue hydration and integrity of membrane under salt conditions when compared to H. vulgare. Hence, our data suggested that the change in the starch storage, distribution of soluble sugar concentrations between source and sink organs, and also changes in the level of enzymes involved in the starch metabolism was significant to give insights into the importance of carbohydrate metabolism in barley species with regards to the salt tolerance. Although these results are still in their nascent state, it could be vital for other researchers to formulate future studies. The preliminary results which were studies about the carbohydrate metabolism and partitioning in salt responses in the halophyte H. marinum and the glycophyte H. vulgare revealed that salt tolerance in barley species is not due to osmotic adjustments, but due to other reasons that were not explored in the past studies. However, the activity of DPE2 in H. vulgare was not hampered by the presence of NaCl as observed. While Pho1 and Pho2, activities were highly increased in cultivated barley. These findings could be suggestive of a possible role of these enzymes in the responses of carbohydrate metabolism to salinity. When sea and cultivated barley species were compared, it was discovered that the former had more versatility in carbohydrate metabolism and distribution.}, language = {en} } @phdthesis{Jung2022, author = {Jung, Jana}, title = {Does youth matter?}, pages = {176}, year = {2022}, abstract = {This dissertation is a compilation of publications and submitted publication manuscripts that seek to improve the understanding of modern partnership trajectories. Romantic relationships constitute one of the most important dimensions in a person's life. They serve to satisfy social and emotional needs (Arr{\´a}nz Becker, 2008) and have an impact on various other dimensions of life. Since the 1970s, partnership formation has been characterized by increased heterogeneity, has become less ordered and much more diverse in terms of living arrangements and the number of unions across the life course (Helske et al, 2015; Ross et al, 2009). This dissertation argues that while partnerships have become more unstable, the need for attachment and the importance of relationship have remained high, if not increased, as evidenced by the prevalence of couple relationships that have remained quite stable (Eckhardt, 2015). The life course perspective (Elder, 1994; Elder et al., 2004; Mayer, 2009) offers an appropriate framework for the understanding of partnership formations throughout the life course. This perspective stresses the path dependency of the life course as well as the interdependencies of life domains (Bernardi et al., 2019). Thus, it can be argued that conditions, resources, and experiences in youth have a substantial influence on later life course outcomes. Given the increasing heterogeneity of partnership trajectories, research to understand partnership processes cannot be based only on single events (e.g., marriage or divorce) or life stages, but must be explored in a dynamic context and over a longer period of time. In sum, this thesis argues that partnership trajectories have to be considered from a holistic perspective. Not only single transitions or events are useful to describe modern partnership histories adequately, but rather the whole process. Additionally, as partnership trajectories are linked to various outcomes (e.g., economics, health, effects on children), it is therefore highly relevant to improve our understanding of partnership dynamics and their determinants and consequences. Findings in this field of research contribute to a better understanding of how childhood and youth are of prospective importance for the later partnership trajectories and whether there are any long-term effects of the conditions and resources formed and stabilized in youth, which then help to understand and explain partnership dynamics. Thus, the interest of this thesis lies in the longitudinal description and prediction of the dynamics of partnership trajectories in light of the individual resources formed and stabilized in youth, as well as in the investigation of the consequences of different partnership trajectory patterns on individual well-being. For these objectives, a high demand on the data is required, as prospective data at the beginning of the partnership biography are needed, as well as data on current life dimensions and the detailed partnership history. The German LifE Study provides this particular data structure as it examines life courses of more than 1,300 individuals from adolescence to middle adulthood. With regard to the overall aim of this dissertation, the main conclusion is that early life conditions, experiences, and resources influence the dynamics of individual partnership trajectories. The results illustrate that youth matters and that characteristics and resources anchored in youth influence the timing of early status passages, which sets individuals on specific life paths. However, in addition to personal and social resources, partnership trajectories were also significantly influenced by individuals' sociodemographic placement. Additionally, individual resources are also linked to the overall turbulence or stability of partnership trajectories. This overall dynamic, which is reflected in different partnership patterns, influences individual well-being, with stability being associated with greater satisfaction, and instability (women), or permanent singlehood (men), having a negative impact on well-being. My analyses contribute to life course research by examining path dependency against the background of various individual factors (socio-structural and psychological characteristics) to model decision-making processes in partnerships in more detail. They do so by including also non-cohabitational union types in the analyses, by accounting for pre-trajectory life conditions and resources, and, most importantly, by modeling the partnership trajectory in a holistic and dynamic perspective, applying this perspective to appropriate and modern statistical methods on a unique dataset.}, language = {en} } @phdthesis{Folwarczny2022, author = {Folwarczny, Uwe}, title = {Lutherische Orthodoxie und konfessioneller Pragmatismus}, series = {Ver{\"o}ffentlichungen aus den Archiven Preußischer Kulturbesitz: Forschungen}, journal = {Ver{\"o}ffentlichungen aus den Archiven Preußischer Kulturbesitz: Forschungen}, number = {20}, publisher = {Duncker \& Humblot}, address = {Berlin}, isbn = {978-3-428-18263-3}, school = {Universit{\"a}t Potsdam}, pages = {625}, year = {2022}, language = {de} } @phdthesis{Herold2022, author = {Herold, Antje}, title = {Das Totenf{\"u}rsorgerecht}, series = {Juristische Schriftenreihe}, journal = {Juristische Schriftenreihe}, number = {306}, publisher = {Lit}, address = {Berlin}, isbn = {978-3-643-25006-3}, school = {Universit{\"a}t Potsdam}, pages = {1210}, year = {2022}, abstract = {Die vorliegende Untersuchung befasst sich mit den allgegenw{\"a}rtigen Fragen, welches rechtliche Schicksal der menschliche K{\"o}rper nach dem Tod nimmt, ob der Leichnam vererbt wird und wer in welchem Umfang {\"u}ber ihn bestimmen darf.

Es handelt sich hierbei um eine Hypersensitivit{\"a}tsreaktion vom Typ IV, die sich nach Allergenkontakt durch Juckreiz, R{\"o}tung, Bl{\"a}schenbildung und Absch{\"a}lung der Haut {\"a}ußert. Zahlreiche Xenobiotika besitzen das Potenzial, Kontaktallergien auszul{\"o}sen, darunter Konservierungsstoffe, Medikamente, Duftstoffe und Chemikalien. Die wirksamste Maßnahme zur Eind{\"a}mmung der Erkrankung ist die Expositionsprophylaxe, also die Vermeidung des Kontakts mit den entsprechenden Substanzen. Dies wiederum setzt die Kenntnis des jeweiligen sensibilisierenden Potenzials einer Substanz voraus, dessen Bestimmung aus diesem Grund eine hohe toxikologische Relevanz besitzt. Zu diesem Zweck existieren von der OECD ver{\"o}ffentlichte Testleitlinien, welche auf entsprechend validierten Testmethoden basieren. Goldstandard bei der Pr{\"u}fung auf hautsensibilisierendes Potenzial war {\"u}ber lange Zeit der murine Lokale Lymphknotentest. Seit der 7. {\"A}nderung der EU-Kosmetikrichtlinie, welche Tierversuche f{\"u}r Kosmetika und deren Inhaltsstoffe untersagt, wurden vermehrt Alternativmethoden in die OECD-Testleitlinien implementiert.. Die bestehenden in vitro Methoden sind jedoch alleinstehend nur begrenzt aussagekr{\"a}ftig, da sie lediglich singul{\"a}re Mechanismen bei der Entstehung einer Kontaktallergie abbilden. Die Entwicklung von Testmethoden, welche mehrere dieser Schl{\"u}sselereignisse ber{\"u}cksichtigen, erscheint daher richtungsweisend. Einen vielversprechenden Ansatz liefert hierbei der Loose-fit coculture-based sensitisation assay (LCSA), welcher eine Kokultur aus prim{\"a}ren Keratinozyten und PBMC darstellt. Bei der Kokultivierung von Immunzellen mit anderen Zelltypen stellt sich allerdings die Frage, inwiefern die Nutzung von Zellen derselben Spender*innen (autologe Kokultur) bzw. verschiedener Spender*innen (allogene Kokultur) einen Einfluss nimmt. Zu diesem Zweck wurden im Rahmen dieser Arbeit Hautzellen spenderspezifisch aus gezupften Haarfollikeln isoliert und der LCSA mit den generierten HFDK in autologen und allogenen Ans{\"a}tzen verglichen. Zus{\"a}tzlich wurde auch ein Vergleich zwischen der Nutzung von HFDK und NHK, welche aus humaner Vorhaut isoliert wurden, im LCSA durchgef{\"u}hrt. Dabei ergaben sich keine signifikanten Unterschiede zwischen autologen und allogenen Kokulturen bzw. zwischen der Verwendung von HFDK und NHK. Die Verwendung allogener Zellen aus anonymem Spendermaterial sowie die Nutzung von Keratinozyten aus unterschiedlichen Quellen scheint im Rahmen des LCSA problemlos m{\"o}glich. Einige der getesteten Kontaktallergene, darunter DNCB und NiCl2, erwiesen sich im LCSA jedoch als problematisch und konnten nicht zufriedenstellend als sensibilisierend detektiert werden. Daher wurde eine Optimierung der Kokultur durch Verwendung ex vivo differenzierter Langerhans Zellen (MoLC) angestrebt, welche ein besseres Modell prim{\"a}rer epidermaler Langerhans Zellen darstellen als die dendritischen Zellen aus dem LCSA. Zus{\"a}tzlich wurden weitere, den Erfolg der Kokultur beeinflussende Faktoren, wie die Art und Zusammensetzung des Mediums und die Kokultivierungsdauer, untersucht und angepasst. Das schlussendlich etablierte Kokultivierungsprotokoll f{\"u}hrte zu einer maßgeblich verst{\"a}rkten Expression von CD207 (Langerin) auf den MoLC, was auf eine wirkungsvolle Interaktion zwischen Haut- und Immunzellen in der Kokultur hindeutete. Des Weiteren konnten DNCB und NiCl2 im Gegensatz zum LCSA durch Verwendung des kostimulatorischen Molek{\"u}ls CD86 sowie des Reifungsmarkers CD83 als Ausleseparameter eindeutig als Kontaktallergene identifiziert werden. Die Untersuchungen zur Kokultur von MoLC und HFDK wurden jeweils vergleichend in autologen und allogenen Ans{\"a}tzen durchgef{\"u}hrt. {\"A}hnlich wie beim LCSA kam es aber auch hier zu keinen signifikanten Unterschieden, weder hinsichtlich der Expression von Charakterisierungs- und Aktivierungsmarkern auf MoLC noch hinsichtlich der Zytokinsekretion in den Zellkultur{\"u}berstand. Die Hinweise aus zahlreichen Studien im Mausmodell, dass Zellen des angeborenen Immunsystems zur Erkennung von und Aktivierung durch allogene Zellen bzw. Gewebe in der Lage sind, best{\"a}tigten sich im Rahmen dieser Arbeit dementsprechend nicht. Aus diesem Grund wurden abschließend CD4+ T-Lymphozyten, die Effektorzellen des adaptiven Immunsystems, in die Kokultur aus MoLC und autologen bzw. allogenen HFDK integriert. {\"U}berraschenderweise traten auch hier keine verst{\"a}rkten Aktivierungen in allogener Kokultur im Vergleich zur autologen Kokultur auf. Die Nutzung autologer Prim{\"a}rzellen scheint im Rahmen der hier getesteten Methoden nicht notwendig zu sein, was die Validierung von Kokulturen und deren Implementierung in die OECD-Testleitlinien erleichtern d{\"u}rfte. Zuletzt wurde eine Kokultivierung prim{\"a}rer Haut- und Immunzellen auch im 3D-Vollhautmodell durchgef{\"u}hrt, wobei autologe MoLC in die Epidermis{\"a}quivalente entsprechender Modelle integriert werden sollten. Obwohl die erstellten Hautmodelle unter Verwendung autologer Haarfollikel-generierter Keratinozyten und Fibroblasten eine zufriedenstellende Differenzierung und Stratifizierung aufwiesen, gestaltete sich die Inkorporation der MoLC als problematisch und konnte im Rahmen dieser Arbeit nicht erreicht werden.}, language = {de} } @phdthesis{Zhou2022, author = {Zhou, Shuo}, title = {Biological evaluation and sulfation of polymer networks from glycerol glycidyl ether}, school = {Universit{\"a}t Potsdam}, pages = {96}, year = {2022}, abstract = {Cardiovascular diseases are the main cause of death worldwide, and their prevalence is expected to rise in the coming years. Polymer-based artificial replacements have been widely used for the treatment of cardiovascular diseases. Coagulation and thrombus formation on the interfaces between the materials and the human physiological environment are key issues leading to the failure of the medical device in clinical implantation. The surface properties of the materials have a strong influence on the protein adsorption and can direct the blood cell adhesion behavior on the interfaces. Furthermore, implant-associated infections will be induced by bacterial adhesion and subsequent biofilm formation at the implantation site. Thus, it is important to improve the hemocompatibility of an implant by altering the surface properties. One of the effective strategies is surface passivation to achieve protein/cell repelling ability to reduce the risk of thrombosis. This thesis consists of synthesis, functionalization, sterilization, and biological evaluation of bulk poly(glycerol glycidyl ether) (polyGGE), which is a highly crosslinked polyether-based polymer synthesized by cationic ring-opening polymerization. PolyGGE is hypothesized to be able to resist plasma protein adsorption and bacterial adhesion due to analogous chemical structure as polyethylene glycol and hyperbranched polyglycerol. Hydroxyl end groups of polyGGE provide possibilities to be functionalized with sulfates to mimic the anti-thrombogenic function of the endothelial glycocalyx. PolyGGE was synthesized by polymerization of the commercially available monomer glycerol glycidyl ether, which was characterized as a mixture of mono-, di- and tri-glycidyl ether. Cationic ring opening-polymerization of this monomer was carried out by ultraviolet (UV) initiation of the photo-initiator diphenyliodonium hexafluorophosphate. With the increased UV curing time, more epoxides in the side chains of the monomers participated in chemical crosslinking, resulting in an increase of Young's modulus, while the value of elongation at break of polyGGE first increased due to the propagation of the polymer chains then decreased with the increase of crosslinking density. Eventually, the chain propagation can be effectively terminated by potassium hydroxide aqueous solution. PolyGGE exhibited different tensile properties in hydrated conditions at body temperature compared to the values in the dry state at room temperature. Both Young's modulus and values of elongation at break were remarkably reduced when tested in water at 37 °C, which was above the glass transition temperature of polyGGE. At physiological conditions, entanglements of the ployGGE networks unfolded and the free volume of networks were replaced by water molecules as softener, which increased the mobility of the polymer chains, resulting in a lower Young's modulus. Protein adsorption analysis was performed on polyGGE films with 30 min UV curing using an enzyme-linked immunosorbent assay. PolyGGE could effectively prevent the adsorption of human plasma fibrinogen, albumin, and fibronectin at the interface of human plasma and polyGGE films. The protein resistance of polyGGE was comparable to the negative controls: the hemocompatible polydimethylsiloxane (PDMS), showing its potential as a coating material for cardiovascular implants. Moreover, antimicrobial tests of bacterial activity using isothermal microcalorimetry and the microscopic image of direct bacteria culturing demonstrated that polyGGE could directly interfere biofilm formation and growth of both Gram-negative and antibiotic-resistant Gram-positive bacteria, indicating the potential application of polyGGE for combating the risk of hospital-acquired infections and preventing drug-resistant superbug spreading. To investigate its cell compatibility, polyGGE films were extracted by different solvents (ethanol, chloroform, acetone) and cell culture medium. Indirect cytotoxicity tests showed extracted polyGGE films still had toxic effects on L929 fibroblast cells. High-performance liquid chromatography/electrospray ionization mass spectrometry revealed the occurrence of organochlorine-containing compounds released during the polymer-cell culture medium interaction. A constant level of those organochlorine-containing compounds was confirmed from GGE monomer by a specific peak of C-Cl stretching in infrared spectra of GGE. This is assumed to be the main reason causing the increased cell membrane permeability and decreased metabolic activity, leading to cell death. Attempts as changing solvents were made to remove toxic substances, however, the release of these small molecules seems to be sluggish. The densely crosslinked polyGGE networks can possibly contribute to the trapping of organochlorine-containing compounds. These results provide valuable information for exploring the potentially toxic substances, leaching from polyGGE networks, and propose a feasible strategy for minimizing the cytotoxicity via reducing their crosslinking density. Sulfamic acid/ N-Methyl-2-pyrrolidone (NMP) were selected as the reagents for the sulfation of polyGGE surfaces. Fourier transform attenuated total reflection infrared spectroscopy (ATR-FT-IR) was used to monitor the functionalization kinetics and the results confirmed the successful sulfate grafting on the surface of polyGGE with the covalent bond -C-O-S-. X-ray photoelectron spectroscopy was used to determine the element composition on the surface and the cross-section of the functionalized polyGGE and sulfation within 15 min guarantees the sulfation only takes place on the surface while not occurring in the bulk of the polymer. The concentration of grafted sulfates increased with the increasing reaction time. The hydrophilicity of the surface of polyGGE was highly increased due to the increase of negatively charged end groups. Three sterilization techniques including autoclaving, gamma irradiation, and ethylene oxide (EtO) sterilization were used for polyGGE sulfates. Results from ATR-FT-IR and Toluidine Blue O quantitative assay demonstrated the total loss of the sulfates after autoclave sterilization, which was also confirmed by the increased water contact angle. Little influence on the concentration of sulfates was found for gamma-irradiated and autoclaving sterilized polyGGE sulfates. To investigate the thermal influence on polyGGE sulfates, one strategy was to use poly(hydroxyethyl acrylate) sulfates (PHEAS) for modeling. The thermogravimetric analysis profile of PHEAS demonstrated that sulfates are not thermally stable independent of the substrate materials and decomposition of sulfates occurs at around 100 °C. Although gamma irradiation also showed little negative effect on the sulfate content, the color change in the polyGGE sulfates indicates chemical or physical change might occur in the polymer. EtO sterilization was validated as the most suitable sterilization technique to maintain the chemical structure of polyGGE sulfates. In conclusion, the conducted work proved that bulk polyGGE can be used as an antifouling coating material and shows its antimicrobial potential. Sulfates functionalization can be effectively realized using sulfamic acid/NMP. EtO sterilization is the most suitable sterilization technique for grafted sulfates. Besides, this thesis also offers a good strategy for the analysis of toxic leachable substances using suitable physicochemical characterization techniques. Future work will focus on minimizing/eliminating the release of toxic substances via reducing the crosslinking density.

Ihr Einfluss auf das beobachtete Ungleichgewicht zwischen pro- und anti-inflammatorischen Cytokinen ist hingegen weitgehend unerforscht. Einige der wichtigsten immunmodulatorischen Cytokine sind die Mitglieder der heterodimeren Interleukin- (IL-) 12-Familie, die durch das Kombinieren einer der drei α-Ketten (IL-12p35, IL-27p28, IL-23p19) mit den ß-Untereinheiten IL-12p40 oder EBI3 (Epstein-Barr Virus-induziertes Gen 3) charakterisiert sind. IL-35 (IL-12p35/EBI3) spielt eine bedeutende anti-inflammatorische Rolle bei verschiedenen Erkrankungen, wohingegen seine Level bei chronischen Entz{\"u}ndungen erniedrigt sind. Eine m{\"o}gliche Ursache k{\"o}nnte eine transkriptionelle Stilllegung {\"u}ber epigenetische Modifikationen sein. Tats{\"a}chlich konnte durch die Stimulation mit dem DNA-Methyltransferase-Inhibitor (DNMTi) Decitabin (DAC; Dacogen®) eine Induktion von EBI3 in humanen Epithelzellen aus gesundem Colon (HCEC) erreicht werden, die als Modell f{\"u}r ein lokales Entz{\"u}ndungsgeschehen dienten. Diese Regulation {\"u}ber DNA-Methylierung konnte in weiteren humanen Zellen unterschiedlichen Ursprungs sowie durch Stimulation von HCEC-Zellen mit zwei weiteren DNMTi, dem Cytosin-Analogon Azacytidin (AZA; Vidaza®) und dem nat{\"u}rlich vorkommenden, epigenetisch wirksamen Polyphenol Epigallocatechingallat (EGCG), verifiziert werden. Die kombinierte Inkubation mit Tumor-Nekrose-Faktor α (TNFα) resultierte jeweils in einer {\"u}ber-additiven Induktion von EBI3. Weiterf{\"u}hrende Untersuchungen zeigten, dass TNFα trotz Beeinflussung der epigenetischen DNMT- und Ten-eleven Translocation- (TET-) Enzyme keinen Einfluss auf die globalen Methylierungs- oder Hydroxymethylierungslevel hatte, jedoch eine genspezifische DNA-Hypomethylierung im EBI3-Promotor induzierte. Durch Nutzung verschiedener Inhibitoren konnte dar{\"u}ber hinaus nachgewiesen werden, dass der beobachtete synergistische Effekt der gemeinsamen DAC und TNFα-Stimulation haupts{\"a}chlich {\"u}ber NFκB (Nuclear factor "kappa-light-chain-enhancer" of activated B-cells) vermittelt wird. Ein Teil verl{\"a}uft dabei {\"u}ber p38 MAPK (mitogen-activated protein kinases), w{\"a}hrend die JNK- (c-Jun N-terminale Kinasen-) und ERK- (extracellular-signal-regulated kinases) Signalwege keine Rolle spielen. In der vorliegenden Arbeit wurde zudem gezeigt, dass die DNA-Hypomethylierung w{\"a}hrend eines entz{\"u}ndlichen Zustandes auch in einer erh{\"o}hten EBI3-Proteinexpression resultiert. Die H{\"o}he der immunologisch detektierten Banden wies auf eine Dimerbildung sowohl im Zelllysat als auch im {\"U}berstand hin. Humane Colonepithelzellen sind demnach in der Lage, Cytokine zu bilden und zu sezernieren, was die Bedeutung von Nicht-Immunzellen bei der lokalen Immunantwort unterstreicht. Mittels Genexpressionsanalysen wurden IL-12p35 und IL-23p19 als m{\"o}gliche Bindungspartner identifiziert. Aufgrund kreuzreaktiver Antik{\"o}rper ist ein direkter Nachweis der EBI3-Dimere derzeit nicht m{\"o}glich. Die stattdessen genutzte Kombination verschiedener Methoden dient als geeigneter Ersatz f{\"u}r die problematischen Antik{\"o}rper-basierten Analysen wie Immunpr{\"a}zipitation oder ELISA. Durch molekularbiologische, immunologische und massenspektrometrische Methoden konnte IL-35 identifiziert werden, w{\"a}hrend IL-39 (IL-23p19/EBI3) nicht detektiert wurde. Dies ist in Einklang mit den Erkenntnissen mehrerer Forschungsgruppen, die eine Bildung des nativen humanen Dimers aus IL-23p19 und EBI3 bezweifeln. Des Weiteren wurde die biologische Aktivit{\"a}t des behandlungsinduzierten IL 35-Proteins durch einen Funktionsassay nachgewiesen. Neben einer DNMTi-bedingten transkriptionellen Aktivierung konnte eine Regulation von EBI3 {\"u}ber Histonacetylierungen gezeigt werden. Der EBI3-induzierende Effekt des Histondeacetylasen-Inhibitors (HDACi) Trichostatin A (TSA) wurde durch SAHA (suberoylanilide hydroxamic acid (Vorinostat; Zolinza®)) verifiziert. {\"A}hnlich zu der Stimulation mit den hypomethylierenden Substanzen wurde ein synergistischer Effekt bei paralleler Inkubation mit TNFα beobachtet, der in einer gesteigerten Bildung des EBI3-Proteins resultierte. Um die Befunde in einem komplexeren in vivo-Modell zu untersuchen, wurde eine chronische Colitis in Ebi3-defizienten M{\"a}usen und dem dazugeh{\"o}rigen Wildtypstamm C57BL/6 durch zyklische Applikation von Natriumdextransulfat (Dextran sodium sulfate (DSS)) induziert. Der Vergleich klinischer Parameter wie Mortalit{\"a}tsrate und K{\"o}rper- sowie Milzgewicht wies bei Abwesenheit von Ebi3 signifikant st{\"a}rkere colitische Symptome auf. Dies best{\"a}tigte die zentrale Rolle von Ebi3 in der Colitisentwicklung und deutete auf eine bevorzugte Bildung des anti-inflammatorisch wirkenden IL-35 statt des pro-inflammatorischen IL-39 in den Wildtyptieren hin. Durch zus{\"a}tzliche therapeutische Behandlung der C57BL/6-M{\"a}use nach der DSS-Gabe konnte die in der Literatur beschriebene positive Wirkung von SAHA auf die Colitismanifestation best{\"a}tigt werden. Im Gegensatz dazu war der HDACi in den Ebi3-defizienten Tieren nicht in der Lage, die colitischen Parameter zu verbessern beziehungsweise verschlimmerte den Krankheitsph{\"a}notyp. Expressionsanalysen von Up- und Downstream-Target-Genen lieferten weitere Hinweise darauf, dass bei Anwesenheit von Ebi3 IL-35 statt IL-39 gebildet wird, was in Einklang mit den in vitro-Untersuchungen steht. Die vorliegende Arbeit konnte durch den Vergleich der C57BL/6-M{\"a}use mit den Ebi3-defizienten Tieren neue Erkenntnisse {\"u}ber die Wirkungsweise von SAHA erbringen. Histonacetylierende Bedingungen verbessern colitische Symptome {\"u}ber einen Mechanismus, der die epigenetische Induktion von Ebi3 mit nachfolgender IL-35-Bildung involviert. Durch Kooperation der epigenetischen Mechanismen Hypomethylierung und Histonacetylierung wurde der st{\"a}rkste Effekt auf die EBI3-Induktion bewirkt. Insgesamt konnte in der vorliegenden Arbeit durch in vitro- und in vivo-Analysen die epigenetische und NFκB-vermittelte Induktion von EBI3 {\"u}ber DNA-Demethylierung und Histonacetylierung mit nachfolgender IL-35-Bildung und -Sezernierung nachgewiesen werden. Da IL-35 in der Lage ist, colitische Symptome zu mildern, stellt die epigenetische Reaktivierbarkeit von EBI3 durch DNMTi und HDACi eine vielversprechende Alternative f{\"u}r die derzeit genutzten, oft nicht oder nur kurzfristig wirksamen Therapien bei der Behandlung einer CU dar.

Residues, consisting of original veterinary drug and transformation products, are found in food products of animal origin as well as the environment (e.g., soil or surface water). Several transformation processes can alter the original veterinary drug, ranging from biotransformation in living organism to environmental degradation processes like photolysis, hydrolysis, or microbial processes. In this thesis, four veterinary drugs were investigated, three ionophore antibiotics Monensin, Salinomycin and Lasalocid and the macrocyclic lactone Moxidectin. Ionophore antibiotics are mainly used to cure and prevent coccidiosis in poultry especially prophylactic in broiler farming. Moxidectin is an antiparasitic drug that is used for the treatment of internal and external parasites in food-producing and companion animals. The main objective of this work is to employ different laboratory approaches to generate and identify transformation products. The identification was conducted using high-resolution mass spectrometry (HRMS). A major focus was placed on the application of electrochemistry for simulation of transformation processes. The electrochemical reactor - equipped with a three-electrode flow-through cell - enabled the oxidation or reduction by applying a potential. The transformation products derived were analyzed by online coupling of the electrochemical reactor and a HRMS and offline by liquid chromatography (LC) combined with HRMS. The main modification reaction of the identified transformation products differed for each investigated veterinary drug. Monensin showed decarboxylation and demethylation as the main modification reactions, for Salinomycin mostly decarbonylation occurred and for Lasalocid methylation was prevalent. For Moxidectin, I observed an oxidation (hydroxylation) reaction and adduct formation with solvent. In general, for Salinomycin and Lasalocid, more transient transformation products (online measurement) than stable transformation products (offline measurements) were detected. By contrast, the number of transformation products using online and offline measurements were identical for Monensin and Moxidectin. As a complementary approach, metabolism tests with rat or human liver microsomes were conducted for the ionophore antibiotics. Monensin was investigated by using rat liver microsomes and the transformation products identified were based on decarboxylation and demethylation. Salinomycin and Lasalocid were converted by human and rat liver microsomes. For both substances, more transformation products were found by using human liver microsomes. The transformation products of the rat liver microsome conversion were redundant, and the transformation products were also found at the human liver microsome assay. Oxidation (hydroxylation) was found to be the main modification reaction for both. In addition, a frequent ion exchange between sodium and potassium was identified. The final two experiments were performed for one substance each, whereby the hydrolysis of Monensin and the photolysis of Moxidectin was investigated. The transformation products of the pH-dependent hydrolysis were based on ring-opening and dehydration. Moxidectin formed several transformation products by irradiation with UV-C light and the main modification reactions were isomeric changes, (de-)hydration and changes of the methoxime moiety. In summary, transformation products of the four investigated veterinary drugs were generated by the different laboratory approaches. Most of the transformation products were identified for the first time. The resulting findings provide an improved understanding of clarifying the transformation behavior.}, language = {en} } @phdthesis{Klockmann2022, author = {Klockmann, Alexander}, title = {Modifizierte Unidirektionale Codes f{\"u}r Speicherfehler}, pages = {92}, year = {2022}, abstract = {Das Promotionsvorhaben verfolgt das Ziel, die Zuverl{\"a}ssigkeit der Datenspeicherung und die Speicherdichte von neu entwickelten Speichern (Emerging Memories) mit Multi-Level-Speicherzellen zu verbessern bzw. zu erh{\"o}hen.

These factors are also linked to intestinal dysbiosis. Additionally, the chronic consumption of diets rich in saturated fats results in body weight gain, hormonal resistances and unfavorable changes in the microbiome composition. The intake of Lactobacilli has already been shown to improve dysbiosis along with metabolism and mood. Yet, the beneficial role and the underlying mechanism of Lactobacillus rhamnosus GG (LGG) to improve emotional behavior in established diet-induced obese conditions are, so far, unknown. To characterize the role of LGG in diet-induced obesity, female and male C57BL/6N mice were fed a semi-synthetic low-fat diet (LFD, 10 \% kcal from fat) or a conventional high-fat diet (HFD, 45 \% kcal from fat) for initial 6 weeks, which was followed by daily oral gavage of vehicle or 1x10^8 CFU of LGG until the end of the experiment. Mice were subjected to basic metabolic and extensive behavioral phenotyping, with a focus on emotional behavior. Moreover, composition of cecal gut microbiome, metabolomic profile in plasma and cerebrospinal fluid was investigated and followed by molecular analyses. Both HFD-feeding and LGG application resulted in sex-specific differences. While LGG prevented the increase of plasma insulin, adrenal gland weight and hyperactivity in diet-induced obese female mice, there was no regulation of anxiodepressive-like behavior. In contrast, metabolism of male mice did not benefit from LGG application, but strikingly, LGG decreased specifically depressive-like behavior in the Mousetail Suspension Test which was confirmed by the Splash Test characterizing motivation for 'self-care'. The microbiome analysis in male mice revealed that HFD-feeding, but not LGG application, altered cecal microbiome composition, indicating a direct effect of LGG on behavioral regulation. However, in female mice, both HFD-feeding and LGG application resulted in changes of microbiome composition, which presumably affected metabolism. Moreover, as diet-induced obese female mice unexpectedly did not exhibit anxiodepressive-like behavior, follow-up analyses were conducted in male mice. Here, HFD-feeding significantly altered abundance of plasma lipids whereas LGG decreased branched chain amino acids which associated with improved emotional behavior. In nucleus accumbens (NAcc) and VTA/SN, which belong to the dopaminergic system, LGG restored HFD-induced decrease of tyrosine hydroxylase, the rate-limiting enzyme in dopamine synthesis, on gene expression level. Lastly, transcriptome analysis in the NAcc identified gene expression of cholecystokinin as a potential mediator of the effect of LGG on HFD-induced emotional alterations. In summary, this thesis revealed the beneficial effects of LGG application on emotional alterations in established diet-induced obesity. Furthermore, both HFD-feeding and LGG treatment exhibited sex-specific effects, resulting in metabolic improvements in female mice while LGG application mitigated depressive-like behavior in obese male mice along with a molecular signature of restored dopamine synthesis and neuropeptide signaling.}, language = {en} } @phdthesis{Wang2022, author = {Wang, Yang}, title = {Role of the actin cytoskeleton in cellular morphogenesis at the shoot apical meristem of Arabidopsis thaliana}, doi = {10.25932/publishup-55908}, school = {Universit{\"a}t Potsdam}, pages = {130}, year = {2022}, abstract = {The morphogenesis of sessile plants is mainly driven by directional cell growth and cell division. The organization of their cytoskeleton and the mechanical properties of the cell wall greatly influence morphogenetic events in plants. It is well known that cortical microtubules (CMTs) contribute to directional growth by regulating the deposition of the cellulose microfibrils, as major cell wall fortifying elements. More recent findings demonstrate that mechanical stresses existing in cells and tissues influence microtubule organization. Also, in dividing cells, mechanical stress directions contribute to the orientation of the new cell wall. In comparison to the microtubule cytoskeleton, the role of the actin cytoskeleton in regulating shoot meristem morphogenesis has not been extensively studied. This thesis focuses on the functional relevance of the actin cytoskeleton during cell and tissue scale morphogenesis in the shoot apical meristem (SAM) of Arabidopsis thaliana. Visualization of transcriptional reporters indicates that ACTIN2 and ACTIN7 are two highly expressed actin genes in the SAM. A link between the actin cytoskeleton and SAM development derives from the observation that the act2-1 act7-1 double mutant has abnormal cell shape and perturbed phyllotactic patterns. Live-cell imaging of the actin cytoskeleton further shows that its organization correlates with cell shape, which indicates a potential role of actin in influencing cellular morphogenesis. In this thesis, a detailed characterization of the act2-1 act7-1 mutant reveals that perturbation of actin leads to more rectangular cellular geometries with more 90° cell internal angles, and higher incidences of four-way junctions (four cell boundaries intersecting together). This observation deviates from the conventional tricellular junctions found in epidermal cells. Quantitative cellular-level growth data indicates that such differences in the act2-1 act7-1 mutant arise due to the reduced accuracy in the placement of the new cell wall, as well as its mechanical maturation. Changes in cellular morphology observed in the act2-1 act7-1 mutant result in cell packing defects that subsequently compromise the flow of information among cells in the SAM.}, language = {en} } @phdthesis{Qin2022, author = {Qin, Miaojing}, title = {The role of heat shock proteins (HSP23s and HSP70-4) for heat stress memory in plants}, school = {Universit{\"a}t Potsdam}, pages = {138}, year = {2022}, abstract = {Heat is a significant climatic condition that threatens crop growth and survival. Extreme temperature occurrences in nature are becoming more severe, more frequent and longer-lasting, all of which have deleterious repercussions for agricultural production. As a result, it is critical to learn more about the mechanisms that lead to increased heat tolerance in plants. To endure and survive, higher plants have evolved complex mechanisms to respond to various amounts of heat stress. Plants have a thermal tolerance that permits them to survive rapid and dramatic temperature rises for a limited time. Plants can also be primed to withstand heat stress (HS) that would otherwise be lethal by exposing them to short, moderate, and non-lethal HS (referred to as a priming stimulus) before being exposed to severe HS. A prepared acquired thermotolerance in primed plants can be maintained for a long time under optimal circumstances, implying that plants can store information during this period. Several studies have shown that acquired thermotolerance (thermopriming) refers to the increased resistance of cells, tissues, and organisms to elevated temperatures after prior heat exposure. Maintenance of acquired thermotolerance (thermomemory) is associated with the synthesis of specialized stress proteins involved in cellular protection and accelerated tissue repair, such as heat shock proteins (HSPs). Recent studies showed a main role of heat shock proteins for turnover of protein quality components, e.g. HSP21 in the chloroplast in the regulation of thermomemory. As an important organelle, mitochondrial function is critical for plant cell responses to heat. However, it is still unknown what the molecular and physiological involvement of HSPs is in mitochondrial function and thermomemory. In our study, we showed that thermopriming induces transcript and protein levels of two mitochondrial small heat shock proteins, HSP23.5 (AT5G51440) and HSP23.6 (AT4G25200), which last for 2-3 days throughout the thermomemory phase. The morphological analysis of HSP23.5/6 transgenic plants demonstrated HSP23.5/6 function redundantly in heat stress. We showed that hsp23.5/6 double knockout plants had abnormalities in thermomemory at the seedling stage, and that mature hsp23.5/6 4 plants are more sensitive to both basal thermotolerance and thermomemory. Heat treatment significantly impacted the respiration rate of hsp23.5/6 seedlings compared to WT, indicating mitochondrial dysfunction dependent on HSP23.5 and HSP23.6. In addition, we tested and confirmed the chaperone activity of HSP23.6 toward the model substrate protein malate dehydrogenase (MDH) in vitro, indicating that HSP23.6 potentially contributes to the maintenance of cellular viability. Furthermore, we discovered a novel HSP23.6 client protein, CIB22, a mitochondrial complex-I subunit protein. According to experimental data (BiFC and Co-IP), HSP23.6 and CIB22 interact in plant cells. We also identified a heat response phenotype in the cib22 mutant compared to WT, as well as CIB22 protein degradation in the hsp23.5/6 mutant when exposed to heat. Our findings suggest that the two mitochondrial-localized heat shock proteins play a role in thermotolerance, presumably by influencing mitochondrial function and structure. More broadly, to identify novel genetic components associated with thermomemory in plants, we performed proteome profiling for Arabidopsis WT (Col-0) seedlings during thermomemory. Multiple time point samples of priming and triggering with controls were collected and analyzed to reveal the dynamic proteome changes during the memory phase in Arabidopsis cells. Among the top memory-associated proteins, we discovered that HSP70-4 was significantly upregulated after priming and remains high (at least 2-fold) for the next four days. By morphologically analyzing their heat stress behaviors, we were able to verify that HSP70-4 is involved in plant heat stress response. More intriguingly, we discovered that following priming, HSP70-4-GFP creates cytosolic foci that persist for a few days into the recovery period. We propose that these foci are linked to SGs due to cycloheximide (CHX) repressing the GFP-foci signal when exposed to heat. These findings indicate an HSP70-4-mediated transcription and translation control link (module) during basal thermotolerance and thermomemory, as well as its potential role(s) in heat stress response.

With its fluctuating nature, HS episodes are frequently interspersed by stress-free intervals. Plants can be primed by HS, allowing them to survive better a recurrent stress episode. A memory of this priming can be maintained during stress-free intervals and this memory is closely correlated with transcriptional memory at several HS-inducible loci. This transcriptional memory is evident from hyper-induction of a locus upon a recurrent HS. ASCORBATE PEROXIDASE 2 (APX2) shows such hyper-induction upon recurring HS, however, the molecular basis of this transcriptional memory is not understood. Previous research showed that the HSinduced transcriptional memory at APX2 can last for up to seven days, and that it is controlled by cis-regulatory elements within the APX2 promoter. To identify regulators involved in HS transcriptional memory, an unbiased forward genetic screening using EMS mutated seeds of pAPX2::LUC was performed from this screen. Two EMS mutants with affected transcriptional memory of LUC were identified. I confirmed that both two EMS mutants resulted from the gene mutations of HISTONE ACETYLTRANSFERASE 1 (HAC1). Besides pAPX2::LUC, the HS-induced transcription of other HS memory genes were also affected in hac1 mutants. Moreover, HAC1 may promote HS transcriptional memory by acetylating promoters of HS memory genes. On the other hand, to identify cis-regulatory elements that are required for transcriptional memory of APX2, I performed promoter analysis of the four conserved HSEs identified within a functional APX2 promoter. I found out that one of the HSEs (HSE1) is necessary for both HS-induced APX2 transcription and transcriptional memory, while another one of HSEs (HSE2) is important for HS-induced APX2 transcriptional memory. I also found out that the HSE1 itself (with 10 bp of flanking sequence) is sufficient to confer HS-induced APX2 transcriptional memory, and HSE1 is also necessary for HSFA2 to bind on APX2 promoter and activate APX2 transcription. The findings will provide important clues for the molecular mechanism of transcriptional memory and will enable engineering of enhanced stress tolerance in crops.}, language = {en} } @phdthesis{Weilandt2022, author = {Weilandt, Maria}, title = {Voil{\`a} une Parisienne!}, publisher = {Transcript}, address = {Bielefeld}, isbn = {978-3-8376-6183-5}, doi = {10.14361/9783839461839}, school = {Universit{\"a}t Potsdam}, pages = {210}, year = {2022}, abstract = {Stereotype sind als kulturgenerierende und dabei stark normierende Figurationen omnipr{\"a}sent.

Nutrient availability affects cell wall composition via uncharacterized regulatory mechanisms, and cellulose deficient mutants develop a hypersensitive root response to growth on high concentrations of nitrate. Since cell walls account for the bulk of plant biomass, it is important to understand how nutrients regulate cell walls. This could provide important knowledge for directing fertilizer treatments and engineering plants with higher nutrient use efficiency. The direct effect of nitrate on cell wall synthesis was investigated through growth assays on varying concentrations of nitrate, measuring cellulose content of roots and shoots, and assessing cellulose synthase activity (CESA) using live cell imaging with spinning disk confocal microscopy. A forward genetic screen was developed to isolate mutants impaired in nutrient-mediated cell wall regulation, revealing that cellulose biosynthesis inhibitor (CBI) activity is modulated by nutrient availability. Various non-CESA mutants were isolated that displayed CBI resistance, with the majority of mutations causing perturbation of mitochondria-localized proteins. To investigate mitochondrial involvement, the CBI mechanism of action was investigated using a reverse genetic screen, a targeted pharmacological screen, and -omics approaches. The results generated suggest that CBI-induced cellulose inhibition is due to off-target effects.

In Germany, where the research for this thesis was conducted, numerous weather extremes occurred in the recent past that caused high numbers of fatalities and huge financial losses. The focus of this research is centred around two relevant natural hazards: heat stress and flooding. Preventing negative health impacts and deaths, as well as structural and monetary damage is the purpose of risk management and this requires citizens to adapt as well. Risk communication is implemented to foster people's risk perception and motivate individual adaptation. However, methods of risk and crisis communication are often not evaluated in a structured manner. Much interdisciplinary research exists on both risk perception and adaptation, however, not much is known on the connection between the two. Furthermore, the existing research on risk communication is often not theory-driven and its impact on individual adaptation and risk perception is not thoroughly documented. This dissertation follows three research aims: (1) Compare psychological theories that contribute to natural hazard research. (2) Explore risk perception and adaptive behaviour by applying multiple methods. And (3) evaluate one risk communication method and one crisis communication method in a theory-driven manner to determine their impact on risk perception and adaptive behaviour. First, a literature review is provided on existing psychological theories which aim to explain the behaviour of individuals with regards to natural hazards. The three key theories included are the Protection Motivation Theory (PMT), the Protective Action Decision Model (PADM), and the Risk Information Seeking and Processing Model (RISP). Each of these are described and compared to each other with a focus on their explanatory power and practical significance in interdisciplinary research. Theoretical adaptations and possible extensions for future research are proposed for the presented approaches. Second, a multimethod field study on heat stress at an open-air event is presented. Face-to-face surveys (n = 306) and behavioural observations (n = 2750) were carried out at a horticultural show in W{\"u}rzburg in summer 2018. The visitors' risk perception, adaptive behaviour, and activity level were analysed and compared between hot days, summer days, and rainy days, applying correlation analyses, ANOVA, and multiple regression analyses. Heat risk perception was generally high, but most respondents were unaware of heat warnings on the day of their visit. During hot days the highest level of adaptation and lower activity levels were observed. Discrepancies between reported and observed adaptation emerged for different age groups.. Third, a telephone and web-based household survey on heat stress was conducted in the cities of W{\"u}rzburg, Potsdam, and Remscheid in 2019 (n = 1417). The PADM served as the study's theoretical framework. In multiple regression analyses the PADM factors of environmental and demographic context, risk communication, and psychological processes explained a substantial share of variance of protection motivation, protective response, and emotion-focused coping. Elements of crisis communication of a heat warning were evaluated experimentally. Results showed that understanding and adaptation intention was significantly higher in individuals that had received action recommendations alongside the heat warning. Fourth, the focus is set on a risk communication method of the flood context. A series of workshops on individual flood protection was carried out in six different settings. The participants (n = 115) answered a pretest-posttest questionnaire. Mixed-model analyses revealed significant increases in self-efficacy, subjective knowledge, and protection motivation. Stronger effects were observed in younger participants and those with lower levels of previous knowledge on flood adaptation as well as no flood experience. The findings of this thesis help to understand individual adaptation, as well as possible impacts of risk and crisis communication on risk perception and adaptation. The scientific background of this work is rooted in the disciplines of psychology and geosciences. The two theories PMT and PADM proved to be useful theoretical frameworks for the presented studies to suggest improvements in risk communication methods. A broad picture of individual adaptation is captured through a variety of methods of self-reports (face-to-face, telephone-based, web-based, and paper-pencil surveys) and behavioural observations, which recorded past and intended behaviour. Alongside with further methodological recommendations, the theory-driven evaluations of risk and crisis communication methods can serve as best-practice examples for future evaluation studies in natural hazard research but also other sciences dealing with risk behaviour to identify and improve effective risk communication pathways.}, language = {en} } @phdthesis{Wolf2022, author = {Wolf, Anne-Christine}, title = {Duales Lernen}, publisher = {Cuvillier}, address = {G{\"o}ttingen}, isbn = {978-3-7369-7648-1}, pages = {248}, year = {2022}, language = {de} } @phdthesis{Schoenfeldt2022, author = {Sch{\"o}nfeldt, Elisabeth}, title = {Giant landslides in Patagonia, Argentina}, pages = {XXII, 156}, year = {2022}, language = {en} } @phdthesis{Epe2022, author = {Epe, Melanie}, title = {Der Gef{\"a}hrdungsschaden}, series = {Nomos Universit{\"a}tsschriften Recht ; 1003}, journal = {Nomos Universit{\"a}tsschriften Recht ; 1003}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {978-3-8487-8630-5}, pages = {354}, year = {2022}, abstract = {Das Konzept des Gef{\"a}hrdungsschadens geh{\"o}rt seit mindestens 130 Jahren zum festen strafrechtlichen Repertoire.

Dabei wird deutlich, wie Programme zur Integration der W{\"a}lder in globale Finanz- und Kohlenstoffm{\"a}rkte zu neuen, experimentellen Formen der »Regierung des Waldes« f{\"u}hren.}, language = {de} } @phdthesis{Biagi2022, author = {Biagi, Enzo}, title = {Pensionskassen}, series = {Recht der Steuern und der {\"o}ffentlichen Finanzordnung = Tax law and public finance}, journal = {Recht der Steuern und der {\"o}ffentlichen Finanzordnung = Tax law and public finance}, number = {25}, publisher = {Nomos Verlagsgesellschaft}, address = {Baden-Baden}, isbn = {978-3-8487-7392-3}, doi = {10.5771/9783748913696}, pages = {314}, year = {2022}, abstract = {Die Kapitalanlage von Pensionskassen in Investmentfonds wird dadurch erschwert, dass sich die sie betreffenden aufsichts- und steuerrechtlichen Normen widersprechen.

It illustrates the use of non-finite constructions and some unique alternative strategies to express adverbial relations with authentic examples in Turkish and German.
