However, there is vast evidence for decadal to centennial scale oscillations and millennial scale climate trends, which are within and beyond a human lifetime perception, respectively. Within the Baltic realm, a transitional zone between oceanic and continental climate influence, the impact of Holocene and Lateglacial climate and environmental change is currently partly understood. This is mainly attributed to the scarcity of well-dated and high-resolution sediment records and to the lacking continuity of already investigated archives. The aim of this doctoral thesis is to reconstruct Holocene and Late Glacial climate variability on local to (over)regional scales based on varved (annually laminated) sediments from Lake Czechowskie down to annual resolution. This project was carried out within the Virtual Institute for Integrated Climate and Landscape Evolution Analyses (ICLEA) and funded by the Helmholtz Association and the Helmholtz Climate Initiative REKLIM (Regional Climate Change). ICLEA intended to gain a better understanding of climate variability and landscape evolution processes in the Northern Central European lowlands since the last deglaciation. REKLIM Topic 8 "Abrupt climate change derived from proxy data" aims at identifying spatiotemporal patterns of climate variability between e.g. higher and lower latitudes. The main aim of this thesis was (i) to establish a robust chronology based on a multiple dating approach for Lake Czechowskie covering the Late Glacial and Holocene and for the Trzechowskie palaeolake for the Lateglacial, respectively, (ii) to reconstruct past climatic and environmental conditions on centennial to multi-millennial time scales and (iii) to distinguish between local to regional different sediments responses to climate change. Addressing the first aim, the Lake Czechowskie chronology has been established by a multiple dating approach comprising information from varve counting, tephrochronology, AMS 14C dating of terrestrial plant remains, biostratigraphy and 137Cs activity concentration measurements. Those independent age constraints covering the Lateglacial and the entire Holocene and have been further implemented in a Bayesian age model by using OxCal v.4.2. Thus, even within non-varved sediment intervals, robust chronological information has been used for absolute age determination. The identification of five cryptotephras, of which three are used as unambiguous isochrones, is furthermore a significant improvement of the Czechowskie chronology and currently unique for the Holocene within Poland. The first findings of coexisting early Holocene H{\"a}sseldalen and Askja-S cryptotephras within a varved sequence even allowed differential dating between both volcanic ashes and stimulated the discussion of revising the absolute ages of the Askja-S tephra. The Trzechowskie palaeolake chronology has been established by a multiple dating approach comprising varve counting, tephrochronology, AMS 14C dating of terrestrial plant remains and biostratigraphy, covers the Lateglacial period (Aller{\o}d and Younger Dryas) and has been implemented in OxCal v.4.2. Those age constraints allowed regional correlation to other high-resolution climate archives and identifying leads and lags of proxy responses at the onset of the Younger Dryas. The second aim has been accomplished by detailed micro-facies and geochemical analyses of the Czechowskie sediments for the entire Holocene. Thus, especially micro-facies changes had been linked to enhanced productivity at Lake Czechowskie. Most prominent changes have been recorded at 7.3, 6.5, 4.3 and 2.8 varve kyrs BP and are linked to a stepwise increasing influence of Atlantic air masses. Especially, the mid-Holocene change, which had been widely reported from palaeohydrological records in low latitudes, has been identified and linked to large scale reorganization of atmospheric circulation patterns. Thus, especially long-term changes of climatic and environmental boundary conditions are widely recorded by the Czechowskie sediments. The pronounced response to (multi)millennial scale changes is further corroborated by the lack of clear sediment responses to early Holocene centennial scale climate oscillations (e.g. the Preboreal Oscillation). However, decadal scale changes at Lake Czechowskie during the most recent period (last 140 years) have been investigated in a lake comparison study. To fulfill the third aim of the doctoral thesis, three lakes in close vicinity to each other have been investigated in order to better distinguish how local, site-specific parameters, may superimpose regional climate driven changes. All lakes haven been unambiguously linked by the Askja AD1875 cryptotephra and independent varve chronologies. As a result, climate warming has only been recorded by sedimentation changes at the smallest and best sheltered lake (Głęboczek), whereas the largest lake (Czechowskie) and the shallowest lake (Jelonek) showed attenuated and less clear sediment responses, respectively. The different responses have been linked to morphological lake characteristics (lake size and depth, catchment area). This study highlights the potential of high-resolution lake comparison for robust proxy based climate reconstructions. In summary, the doctoral thesis presents a high-resolution sediment record with an underlying age model, which is prerequisite for unprecedented age control down to annual resolution. Sediment proxy based climate reconstructions demonstrate the importance of the Czechowskie sediments for better understanding climate variability in the southern Baltic realm. Case studies showed the clear response on millennial time scale, while decadal scale fluctuations are either less well expressed or superimposed by local, site-specific parameters. The identification of volcanic ash layers is not only used for unambiguous isochrones, those are key tie lines for local to supra regional archive synchronization and establish the Lake Czechowskie as a key climate archive.}, language = {en} } @book{LudwigMarxTaschetal.2018, author = {Ludwig, Joachim and Marx, Silvia and Tasch, Markus and Utech, Henry}, title = {d.art}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-413642}, publisher = {Universit{\"a}t Potsdam}, pages = {149}, year = {2018}, abstract = {Der Konzeptband dokumentiert den Aufbau und die Durchf{\"u}hrung der p{\"a}dagogischen Weiterbildung „d.art".

During the data processing these time series are divided into small segments and for each segment spectral values are computed which are typically averaged in a statistical manner to obtain MT transfer functions. Unfortunately, the presence of man-made EM noise sources often deteriorates a significant amount of the recorded time series resulting in disturbed transfer functions. Many advanced processing techniques, e.g. robust statistics, pre-stack data selection or remote reference, have been developed to tackle this problem. The first two techniques reduce the amount of outliers and noise in the data whereas the latter approach removes noise by using data from another MT station. However, especially in populated regions the data processing is still quite challenging even with these approaches. In this thesis, I present two novel pre-stack data confinement and selection criteria for the detection of outliers and noise affected data based on (i) a distance measure of each data segment with regard to the entire sample distribution and (ii) the evaluation of the magnetic polarisation direction of all segments. The first criterion is able to remove data points that scatter around the desired MT distribution and furthermore it can, under some circumstances, even reject complete data cluster originating from noise sources. The second criterion eliminates data points caused by a strongly polarised magnetic signal. Both criteria have been successfully applied to many stations with different noise contaminations showing that they can significantly improve the transfer function estimation. The novel criteria were used to evaluate a MT data set from the Eastern Karoo Basin in South Africa. The corresponding field experiment is part of an extensive research programme to collect information of the current e.g. geological setting in this region prior to a potential shale gas exploitation. The aim was to investigate whether a three-dimensional (3D) inversion of the newly measured data fosters a more realistic mapping of physical properties of the target horizon. For this purpose, a comprehensive 3D model was derived by using all available data. In a second step, I analysed parameters of the target horizon, e.g. its conductivity, that are proxies for physical properties such as thermal maturity and porosity.}, language = {en} } @phdthesis{Seppelt2018, author = {Seppelt, Svetlana}, title = {Novellierungsbedarf im Recht der privaten Sicherheitsdienste}, series = {Schriftenreihe Studien zur Rechtswissenschaft}, journal = {Schriftenreihe Studien zur Rechtswissenschaft}, number = {418}, publisher = {Dr. Kovač}, address = {Hamburg}, isbn = {978-3-339-10340-6}, school = {Universit{\"a}t Potsdam}, pages = {XXVII, 343}, year = {2018}, language = {de} } @masterthesis{Haug2018, type = {Bachelor Thesis}, author = {Haug, Frederik}, title = {Verbrannte Erde}, series = {WeltTrends Thesis}, journal = {WeltTrends Thesis}, number = {21}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-434-0}, issn = {1866-0738}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-411237}, school = {Universit{\"a}t Potsdam}, pages = {74}, year = {2018}, abstract = {Innerhalb des {\"o}ffentlichen und politischen Diskurses in Deutschland nehmen die Verbrechen in den ehemaligen Kolonien des Deutschen Kaiserreichs einen kaum wahrnehmbaren Platz ein.

Our knowledge of past climate changes is therefore almost exclusively based on indirect proxy data, i.e. on indicators which are sensitive to changes in climatic variables and stored in environmental archives. Extracting the data from these archives allows retrieval of the information from earlier times. Obtaining accurate proxy information is a key means to test model predictions of the past climate, and only after such validation can the models be used to reliably forecast future changes in our warming world. The polar ice sheets of Greenland and Antarctica are one major climate archive, which record information about local air temperatures by means of the isotopic composition of the water molecules embedded in the ice. However, this temperature proxy is, as any indirect climate data, not a perfect recorder of past climatic variations. Apart from local air temperatures, a multitude of other processes affect the mean and variability of the isotopic data, which hinders their direct interpretation in terms of climate variations. This applies especially to regions with little annual accumulation of snow, such as the Antarctic Plateau. While these areas in principle allow for the extraction of isotope records reaching far back in time, a strong corruption of the temperature signal originally encoded in the isotopic data of the snow is expected. This dissertation uses observational isotope data from Antarctica, focussing especially on the East Antarctic low-accumulation area around the Kohnen Station ice-core drilling site, together with statistical and physical methods, to improve our understanding of the spatial and temporal isotope variability across different scales, and thus to enhance the applicability of the proxy for estimating past temperature variability. The presented results lead to a quantitative explanation of the local-scale (1-500 m) spatial variability in the form of a statistical noise model, and reveal the main source of the temporal variability to be the mixture of a climatic seasonal cycle in temperature and the effect of diffusional smoothing acting on temporally uncorrelated noise. These findings put significant limits on the representativity of single isotope records in terms of local air temperature, and impact the interpretation of apparent cyclicalities in the records. Furthermore, to extend the analyses to larger scales, the timescale-dependency of observed Holocene isotope variability is studied. This offers a deeper understanding of the nature of the variations, and is crucial for unravelling the embedded true temperature variability over a wide range of timescales.}, language = {en} } @article{Hennemann2018, author = {Hennemann, Anja}, title = {Evidentiality and (Inter-) Subjectivity as (Non-) Competing Dimensions}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-414996}, year = {2018}, abstract = {The present paper discusses the relationship between evidentiality and (inter-) subjectivity and argues that the two semantic-functional categories need not be mutually exclusive.

Atom transfer radical polymerization (ATRP) as one of the most extensive studied types of RDRP has been particularly emphasized due to the high accessibility to hybrid materials, multifunctional copolymers and diverse end group functionalities via commercially available precursors. However, due to catalyst-induced side reactions and chain-chain coupling termination in bulk environment, synthesis of high MW polymers with uniform chain length (low Ɖ) and highly-preserved chain-end fidelity is usually challenging. Besides, owing to the inherited radical nature, the control of microstructure, namely tacticity control, is another laborious task. Considering the applied catalysts, the utilization of large amounts of non-reusable transition metal ions which lead to cumbersome purification process, product contamination and complicated reaction procedures all delimit the scope ATRP techniques. Metal-organic frameworks (MOFs) are an emerging type of porous materials combing the properties of both organic polymers and inorganic crystals, characterized with well-defined crystalline framework, high specific surface area, tunable porous structure and versatile nanochannel functionalities. These promising properties of MOFs have thoroughly revolutionized academic research and applications in tremendous aspects, including gas processing, sensing, photoluminescence, catalysis and compartmentalized polymerization. Through functionalization, the microenvironment of MOF nanochannel can be precisely devised and tailored with specified functional groups for individual host-guest interactions. Furthermore, properties of high transition metal density, accessible catalytic sites and crystalline particles all indicate MOFs as prominent heterogeneous catalysts which open a new avenue towards unprecedented catalytic performance. Although beneficial properties in catalysis, high agglomeration and poor dispersibility restrain the potential catalytic capacity to certain degree. Due to thriving development of MOF sciences, fundamental polymer science is undergoing a significant transformation, and the advanced polymerization strategy can eventually refine the intrinsic drawbacks of MOF solids reversely. Therefore, in the present thesis, a combination of low-dimensional polymers with crystalline MOFs is demonstrated as a robust and comprehensive approach to gain the bilateral advantages from polymers (flexibility, dispersibility) and MOFs (stability, crystallinity). The utilization of MOFs for in-situ polymerizations and catalytic purposes can be realized to synthesize intriguing polymers in a facile and universal process to expand the applicability of conventional ATRP methodology. On the other hand, through the formation of MOF/polymer composites by surface functionalization, the MOF particles with environment-adjustable dispersibility and high catalytic property can be as-prepared. In the present thesis, an approach via combination of confined porous textures from MOFs and controlled radical polymerization is proposed to advance synthetic polymer chemistry. Zn2(bdc)2(dabco) (Znbdc) and the initiator-functionalized Zn MOFs, ZnBrbdc, are utilized as a reaction environment for in-situ polymerization of various size-dependent methacrylate monomers (i.e. methyl, ethyl, benzyl and isobornyl methacrylate) through (surface-initiated) activators regenerated by electron transfer (ARGET/SI-ARGET) ATRP, resulting in polymers with control over dispersity, end functionalities and tacticity with respect to distinct molecular size. While the functionalized MOFs are applied, due to the strengthened compartmentalization effect, the accommodated polymers with molecular weight up to 392,000 can be achieved. Moreover, a significant improvement in end-group fidelity and stereocontrol can be observed. The results highlight a combination of MOFs and ATRP is a promising and universal methodology to synthesize versatile well-defined polymers with high molecular weight, increment in isotactic trial and the preserved chain-end functionality. More than being a host only, MOFs can act as heterogeneous catalysts for metal-catalyzed polymerizations. A Cu(II)-based MOF, Cu2(bdc)2(dabco), is demonstrated as a heterogeneous, universal catalyst for both thermal or visible light-triggered ARGET ATRP with expanded monomer range. The accessible catalytic metal sites enable the Cu(II) MOF to polymerize various monomers, including benzyl methacrylate (BzMA), styrene, methyl methacrylate (MMA), 2-(dimethylamino)ethyl methacrylate (DMAEMA) in the fashion of ARGET ATRP. Furthermore, due to the robust frameworks, surpassing the conventional homogeneous catalyst, the Cu(II) MOF can tolerate strongly coordinating monomers and polymerize challenging monomers (i.e. 4-vinyl pyridine, 2-vinyl pyridine and isoprene), in a well-controlled fashion. Therefore, a synthetic procedure can be significantly simplified, and catalyst-resulted chelation can be avoided as well. Like other heterogeneous catalysts, the Cu(II) MOF catalytic complexes can be easily collected by centrifugation and recycled for an arbitrary amount of times. The Cu(II) MOF, composed of photostimulable metal sites, is further used to catalyze controlled photopolymerization under visible light and requires no external photoinitiator, dye sensitizer or ligand. A simple light trigger allows the photoreduction of Cu(II) to the active Cu(I) state, enabling controlled polymerization in the form of ARGET ATRP. More than polymerization application, the synergic effect between MOF frameworks and incorporated nucleophilic monomers/molecules is also observed, where the formation of associating complexes is able to adjust the photochemical and electrochemical properties of the Cu(II) MOF, altering the band gap and light harvesting behavior. Owing to the tunable photoabsorption property resulting from the coordinating guests, photoinduced Reversible-deactivation radical polymerization (PRDRP) can be achieved to further simplify and fasten the polymerization. More than the adjustable photoabsorption ability, the synergistic strategy via a combination of controlled/living polymerization technique and crystalline MOFs can be again evidenced as demonstrated in the MOF-based heterogeneous catalysts with enhanced dispersibility in solution. Through introducing hollow pollen pivots with surface immobilized environment-responsive polymer, PDMAEMA, highly dispersed MOF nanocrystals can be prepared after associating on polymer brushes via the intrinsic amine functionality in each DMAEMA monomer. Intriguingly, the pollen-PDMAEMA composite can serve as a "smart" anchor to trap nanoMOF particles with improved dispersibility, and thus to significantly enhance liquid-phase photocatalytic performance. Furthermore, the catalytic activity can be switched on and off via stimulable coil-to-globule transition of the PDMAEMA chains exposing or burying MOF catalytic sites, respectively.}, language = {en} } @book{OPUS4-40576, title = {www.BrAnD2.Wissen.}, number = {10}, editor = {H{\"o}mke, Nicola}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-424-1}, issn = {1860-5206}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-405764}, publisher = {Universit{\"a}t Potsdam}, pages = {248}, year = {2018}, abstract = {Mit „Wissen" kommt der zweite Durchgang des insgesamt dreij{\"a}hrigen Brandenburger Antike-Denkwerks zum Abschluss, das der Zusammenarbeit zwischen der Klassischen Philologie der Universit{\"a}t Potsdam und ausgew{\"a}hlten Brandenburger Gymnasien dient und von der Robert Bosch Stiftung gef{\"o}rdert wird.

Zadok's innovative writings. According to most scholars R. Zadok continues the doctrine of his rabbi R. Mordechai Yosef Leiner of Izbica and introduces existential fatalism: man has the freedom to act against the customary law, according to God's will which is revealed in his heart, even in his passions, which exceed the Halacha; however, man does not determine the will that is revealed in the root of his soul, but only uncovers it. Many expressions, in content and form, of this fatalism can be found in R. Zadok's writings; yet, he also introduces many remarks about human free choice and its creative power to establish and determine man's root and re-establish and influence the Divine worlds and this world. This research focuses on these passages whose centrality has been so far neglected by research. Hence, its renewed understanding of his doctrine. R. Zadok's position can be explained by means of the paradoxical perception, which claims the full strength of the two opposites and even a mutual influence between them, which creates a difficult yet fertile tension: as opposed to the a priori intellectual and formal process of fatalism where Divine Foreknowledge eliminates free choice, R. Zadok introduces fatality which identifies in reality itself the Divine foreknowledge and will that exist in all things. In R. Zadok's fatality, Divine foreknowledge does not eliminate free choice; on the contrary, without Divine foreknowledge, nothing has existence. Therefore, only the existence of Divine foreknowledge within free choice enables its true and indeed free fulfillment. R. Zadok's ontological perception is realized not only in the direct content of his words but also indirectly, in the method of his exegesis and the sense he gives to the concepts he discusses. Therefore the fatality is revealed in other areas in which there is a gap between the absolute dimension ('Yedi'ah') and the contingent dimension ('Bechirah'): the lie, imagination, evil, sin, suffering etc., indeed contingent compared with the absoluteness of truth, good, etc.; however, according to R. Zadok, God wants them as such - that is to say, they have an essential existence and actuality that are not absolute, but rather as such: as contingent, temporary and relative. However, these essential existence and actuality do not confirm them as they are but create a transformation within them. For example, evil does not become absolute good or remains evil but rather turns into 'Very Good' (Tov Me'od) which includes evil and according to Rabbi Zadok is greater than regular good. From this, rises also the opposite influence: that of free choice, or contingent Bechira in general, on Divine Foreknowledge, or absolute Yediah in general. According to R. Zadok, when the contingency and relativity of "Bechirah" received its essential existence and actuality, it has the power so to speak, to add dynamism to the permanent Divine absoluteness of the 'Yedi'ah': the affliction (Nega; נגע) of sin or suffering turns by itself, by interchanging its letters, into pleasure (Oneg; ענג) which is greater than regular delight. Man has the power to influence the upper worlds by decreeing decrees or by canceling Divine decrees; he also has the power to influence the daily novelties of this world, by the novellaes of the Oral Law and the sanctification of the new month which is capable of changing the movement of the zodiac. The human creativity of the novellae of the Oral Law is included in the Divine truth which is hidden in the Written Law and it only reveals and interprets the latter; but on the other hand, according to R. Zadok, the source of the dynamic vital novellaes of the Oral Law is higher than the source of the permanent absoluteness of Written Law and they are those which create and determine the latter. R. Zadok introduces two main concepts for his paradox: On the ontological perception - Yichud Gamur, the Ultimate Unification of God, in which the contingent duality (between God and His creation, and the choice it enables) of the Lower Unification paradoxically exists with the absolute unification and Divine Foreknowledge of the Upper Unification. On the perception of man's existential situation - HaShoresh HaNe'elam, The Hidden Root: unlike Rabbi Mordechai Yosef, his rabbi, rabbi Zadok claims that man determines his destiny by his willful contingent actions - yet, simultaneously, like his rabbi, he also claims that the man's permanent root is determined by God and His Foreknowledge and it is what determines his actions for better or worse. But above these R. Zadok points to an additional Hidden Root which is higher than the permanent one: it is indeed an absolute root (Yediah) yet is determined and established by man's willful actions (Bechira), similar to the Divine creation of 'ex nihilo'.}, language = {mul} } @phdthesis{Gruetze2018, author = {Gr{\"u}tze, Toni}, title = {Adding value to text with user-generated content}, school = {Universit{\"a}t Potsdam}, pages = {ii, 114}, year = {2018}, abstract = {In recent years, the ever-growing amount of documents on the Web as well as in closed systems for private or business contexts led to a considerable increase of valuable textual information about topics, events, and entities. It is a truism that the majority of information (i.e., business-relevant data) is only available in unstructured textual form. The text mining research field comprises various practice areas that have the common goal of harvesting high-quality information from textual data. These information help addressing users' information needs. In this thesis, we utilize the knowledge represented in user-generated content (UGC) originating from various social media services to improve text mining results. These social media platforms provide a plethora of information with varying focuses. In many cases, an essential feature of such platforms is to share relevant content with a peer group. Thus, the data exchanged in these communities tend to be focused on the interests of the user base. The popularity of social media services is growing continuously and the inherent knowledge is available to be utilized. We show that this knowledge can be used for three different tasks. Initially, we demonstrate that when searching persons with ambiguous names, the information from Wikipedia can be bootstrapped to group web search results according to the individuals occurring in the documents. We introduce two models and different means to handle persons missing in the UGC source. We show that the proposed approaches outperform traditional algorithms for search result clustering. Secondly, we discuss how the categorization of texts according to continuously changing community-generated folksonomies helps users to identify new information related to their interests. We specifically target temporal changes in the UGC and show how they influence the quality of different tag recommendation approaches. Finally, we introduce an algorithm to attempt the entity linking problem, a necessity for harvesting entity knowledge from large text collections. The goal is the linkage of mentions within the documents with their real-world entities. A major focus lies on the efficient derivation of coherent links. For each of the contributions, we provide a wide range of experiments on various text corpora as well as different sources of UGC. The evaluation shows the added value that the usage of these sources provides and confirms the appropriateness of leveraging user-generated content to serve different information needs.}, language = {en} } @phdthesis{Roes2018, author = {Roes, Michel}, title = {Corporate Social Responsibility und finanzielle Performance von b{\"o}rsennotierten Unternehmen}, series = {Schriftenreihe Finanzierung und Banken}, volume = {2018}, journal = {Schriftenreihe Finanzierung und Banken}, number = {31}, publisher = {Wissenschaft \& Praxis}, address = {Sternenfels}, isbn = {978-3-89673-748-9}, school = {Universit{\"a}t Potsdam}, pages = {XVII, 284}, year = {2018}, language = {de} } @book{Holtmann2018, author = {Holtmann, Dieter}, title = {The development of living standards after the world financial crisis in 43 countries and six welfare regimes}, series = {Potsdamer Beitr{\"a}ge zur Sozialforschung}, journal = {Potsdamer Beitr{\"a}ge zur Sozialforschung}, number = {43}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-414833}, publisher = {Universit{\"a}t Potsdam}, pages = {77}, year = {2018}, language = {de} } @phdthesis{SarnesNitu2018, author = {Sarnes-Nitu, Juliane}, title = {Mit der Schuldenbremse zu nachhaltigen Staatsfinanzen?}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-413804}, school = {Universit{\"a}t Potsdam}, pages = {294}, year = {2018}, abstract = {The core question of this paper is: Does the debt brake secure fiscal sustainability in Germany? To answer this question, we will first examine the effects of the introduction of the debt brake on the German federal states in the period 2010-16. For this purpose, the observed consolidation performance and the consolidation incentive or pressure experienced by the federal states were evaluated with the help of a scorecard specifically developed for this purpose. Multiple regression analysis was used to analyze how the scorecard factors affect the consolidation performance of the federal states. It found that nearly 90\% of the variation was explained by the independent variables budgetary position, debt burden, revenue growth and pension burden. Thus the debt brake likely played a subordinate role in the 2009-2016 consolidation episode. Subsequently, the data collected in 65 expert interviews was used to analyze the limits of the new fiscal rule, and to determine which potential risks could hinder or prevent the debt brake in the future: municipal debt, FEUs, contingent liabilities in the form of guarantees for financial institutions and pension obligations. The frequently expressed criticism that the debt brake impedes economic growth and public investments is also reviewed and rejected.

The overarching subject is concerned with the relationship between creativity, freedom, and control, considering freedom is also seen as an element of control to manage creativity. Design/methodology/approach - In-depth qualitative data gathered from at two innovative start-ups. Two ethnographic studies were conducted. The data are based on participatory observations, interviews, and secondary sources, each of which included a three months field study and a total of 41 interviews from both organizations. Findings - The thesis provides explanations for the practice of freedom and the control of creativity within organizations and expands the existing theory of neo-normative control. The findings indicate that organizations use complex control systems that allow a high degree of freedom that paradoxically leads to more control. Freedom is a cover of control, which in turn leads to creativity. Covert control even results in the responsibility to be creative outside working hours. Practical implications - Organizations, which rely on creativity might use the results of this thesis. Positive workplace control of creativity provides both freedom and structure for creative work. While freedom leads to organizational members being more motivated and committing themselves more strongly to their and the organization's goals, and a specific structure also helps to provide the requirements for creativity. Originality/value - The thesis provides an insight into an approach to workplace control, which has mostly neglected in creativity research and proposes a modified concept of neo-normative control.

Such low-relief landforms are also preferred locations for humans to settle in otherwise steep and poorly accessible terrain. Abundant water and sediment as essential sources for buildings and infrastructure make these areas amenable places to live at. Yet valley floors are also prone to rare and catastrophic sedimentation that can overload river systems by abruptly increasing the volume of sediment supply, thus causing massive floodplain aggradation, lateral channel instability, and increased flooding. Some valley-fill sediments should thus record these catastrophic sediment pulses, allowing insights into their timing, magnitude, and consequences. This thesis pursues this theme and focuses on a prominent ~150 km2 valley fill in the Pokhara Valley just south of the Annapurna Massif in central Nepal. The Pokhara Valley is conspicuously broad and gentle compared to the surrounding dissected mountain terrain, and is filled with locally more than 70 m of clastic debris. The area's main river, Seti Khola, descends from the Annapurna Sabche Cirque at 3500-4500 m asl down to 900 m asl where it incises into this valley fill. Humans began to settle on this extensive fan surface in the 1750's when the Trans-Himalayan trade route connected the Higher Himalayas, passing Pokhara city, with the subtropical lowlands of the Terai. High and unstable river terraces and steep gorges undermined by fast flowing rivers with highly seasonal (monsoon-driven) discharge, a high earthquake risk, and a growing population make the Pokhara Valley an ideal place to study the recent geological and geomorphic history of its sediments and the implication for natural hazard appraisals. The objective of this thesis is to quantify the timing, the sedimentologic and geomorphic processes as well as the fluvial response to a series of strong sediment pulses. I report diagnostic sedimentary archives, lithofacies of the fan terraces, their geochemical provenance, radiocarbon-age dating and the stratigraphic relationship between them. All these various and independent lines of evidence show consistently that multiple sediment pulses filled the Pokhara Valley in medieval times, most likely in connection with, if not triggered by, strong seismic ground shaking. The geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation tied to the timing of three medieval Himalayan earthquakes in ~1100, 1255, and 1344 AD. Sediment provenance and calibrated radiocarbon-age data are the key to distinguish three individual sediment pulses, as these are not evident from their sedimentology alone. I explore various measures of adjustment and fluvial response of the river system following these massive aggradation pulses. By using proxies such as net volumetric erosion, incision and erosion rates, clast provenance on active river banks, geomorphic markers such as re-exhumed tree trunks in growth position, and knickpoint locations in tributary valleys, I estimate the response of the river network in the Pokhara Valley to earthquake disturbance over several centuries. Estimates of the removed volumes since catastrophic valley filling began, require average net sediment yields of up to 4200 t km-2 yr-1 since, rates that are consistent with those reported for Himalayan rivers. The lithological composition of active channel-bed load differs from that of local bedrock material, confirming that rivers have adjusted 30-50\% depending on data of different tributary catchments, locally incising with rates of 160-220 mm yr-1. In many tributaries to the Seti Khola, most of the contemporary river loads come from a Higher Himalayan source, thus excluding local hillslopes as sources. This imbalance in sediment provenance emphasizes how the medieval sediment pulses must have rapidly traversed up to 70 km downstream to invade the downstream reaches of the tributaries up to 8 km upstream, thereby blocking the local drainage and thus reinforcing, or locally creating new, floodplain lakes still visible in the landscape today. Understanding the formation, origin, mechanism and geomorphic processes of this valley fill is crucial to understand the landscape evolution and response to catastrophic sediment pulses. Several earthquake-triggered long-runout rock-ice avalanches or catastrophic dam burst in the Higher Himalayas are the only plausible mechanisms to explain both the geomorphic and sedimentary legacy that I document here. In any case, the Pokhara Valley was most likely hit by a cascade of extremely rare processes over some two centuries starting in the early 11th century. Nowhere in the Himalayas do we find valley fills of comparable size and equally well documented depositional history, making the Pokhara Valley one of the most extensively dated valley fill in the Himalayas to date. Judging from the growing record of historic Himalayan earthquakes in Nepal that were traced and dated in fault trenches, this thesis shows that sedimentary archives can be used to directly aid reconstructions and predictions of both earthquake triggers and impacts from a sedimentary-response perspective. The knowledge about the timing, evolution, and response of the Pokhara Valley and its river system to earthquake triggered sediment pulses is important to address the seismic and geomorphic risk for the city of Pokhara. This thesis demonstrates how geomorphic evidence on catastrophic valley infill can help to independently verify paleoseismological fault-trench records and may initiate re-thinking on post-seismic hazard assessments in active mountain regions.}, language = {en} } @misc{Eckstein2018, author = {Eckstein, Lars}, title = {Recollecting bones}, series = {Postcolonial Studies}, journal = {Postcolonial Studies}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-413654}, pages = {15}, year = {2018}, abstract = {This article critically engages with the different politics of memory involved in debates over the restitution of Indigenous Australian ancestral remains stolen by colonial actors in the nineteenth and early twentieth centuries and brought to Berlin in the name of science.

I examine both functions of the Arctic via a reading of the dispute over the Northwest Passage (which emphasizes the Arctic as a space of transit) and the contemporary assessment of new models of sovereignty in the Arctic region (which concentrates on the circumpolar Arctic as an oceanic world). However, both of these debates frequently exclude indigenous positions on the Arctic. By reading Canadian Inuit theories on the Arctic alongside the more prominent debates, I argue for a decolonizing reading of the Arctic inspired by Inuit articulations of the "Inuit Sea."

Since our environmental factors are constantly changing because of anthropogenic influences, the question arises as to how far we have an impact on the human phenotype in the very sensitive growth phase in children and adolescents. Growth and development of all children and adolescents follow a universal and typical pattern. This pattern has evolved as the result of trade-offs in the 6-7 million years of human evolution. This typically human growth pattern differs from that of other long-living social primate species. It can be divided into different biological age stages, with specific biological, cognitive and socio-cultural signs. Phenotypic plasticity is the ability of an organism to react to an internal or external environmental input with a change in the form, state, and movement rate of activity (West-Eberhard 2003). The plasticity becomes visible and measurable particularly when, in addition to the normal variability of the phenotypic characteristics within a population, the manifestation of this plasticity changes within a relatively short time. The focus of the present work is the comparison of age-specific dimensional changes. The basic of the presented studies are more than 75,000 anthropometric data-sets of children and adolescence from 1980 up today and historical data of height available in scientific literature. Due to reduced daily physical activity, today's 6-18 year-olds have lower values of pelvic and elbow breadths. The observed increase in body height can be explained by hierarchies in social networks of human societies, contrary to earlier explanations (influence of nutrition, good living conditions and genetics). A shift towards a more feminine fat distribution pattern in boys and girls is parallel to the increase in chemicals in our environment that can affect the hormone system. Changing environmental conditions can have selective effects over generations so that that genotype becomes increasingly prevalent whose individuals have a higher progeny rate than other individuals in this population. Those then form the phenotype which allows optimum adaptation to the changes of the environmental conditions. Due to the slow patterns of succession and the low progeny rate (Hawkes et al. 1998), fast visible in the phenotype due to changes in the genotype of a population are unlikely to occur in the case of Homo sapiens sapiens within short time. In the data sets on which the presented investigations are based, such changes appear virtually impossible. The study periods cover 5-30 to max.100 years (based on data from the body height from historical data sets).}, language = {en} } @book{OPUS4-41381, title = {Nachdenken {\"u}ber Europa}, editor = {Kr{\"a}mer, Raimund}, publisher = {WeltTrends}, address = {Potsdam}, isbn = {978-3-945878-93-4}, publisher = {Universit{\"a}t Potsdam}, pages = {231}, year = {2018}, language = {de} } @phdthesis{Aktan2018, author = {Aktan, Oktay}, title = {Turkish football clubs in Berlin}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-413616}, school = {Universit{\"a}t Potsdam}, pages = {221}, year = {2018}, abstract = {Es gibt in Berlin eine einzigartige Vereinslandschaft im Amateur - und semiprofessionellen Fußballsport, in der einst von t{\"u}rkischen Migranten gegr{\"u}ndete Vereine einen festen Platz einnehmen.

In Folge dessen werden in diesem Raum Anerkennungsmechanismen konstituiert. Die vorliegende Dissertation befasst sich mit dem allt{\"a}glichen Leben von t{\"u}rkisch-st{\"a}mmigen, jugendlichen Amateur- und semiprofessionellen Fußballspielern (delikanli), sowie von anderen sozialen Akteuren der t{\"u}rkischen Fußballwelt, wie zum Beispiel „{\"a}ltere" Fußballspieler (agbi) und Fußballtrainer (hoca). Hauptanliegen der Arbeit war die Rekonstruktion kollektiver Wahrnehmungs-, Deutungs - und Handlungsmuster von Mitgliedern t{\"u}rkischer Fußballvereine im allgemeinen und ihrer Selbstdarstellung aber auch ihrer Wahrnehmung der „Anderen" im besonderen. Mittels dieser Studie sollte nachvollzogen werden, ob und inwiefern sich traditionelle soziale Verhaltensmuster der gew{\"a}hlten Gruppe im technisch regulierten und stark Konkurrenz-orientierten Handlungsraum widerspiegeln und die reziproken Beziehungen zwischen dem „Selbst" und den „Anderen" regulieren. Dabei wurde die Relevanz von herkunftsbezogenen Stereotypisierungen und Vorurteilen in der kollektiven Konstitution von Selbstwahrnehmungen und Fremdverstehen im partikularen sozialen Feld (Bourdieu, 2001) des Fußballs rekonstruiert. In dieser Arbeit wurde dar{\"u}ber hinaus beleuchtet, welche Rolle t{\"u}rkische Fußballvereine auf der einen Seite bei der Entstehung sozialer Raumzugeh{\"o}rigkeit zu den Stadtquartieren in Berlin einnehmen und welche Art von Mechanismen der sozialen Integration sie in diesen Vereinen herstellen. Auf der anderen Seite wurde hinterfragt, inwiefern sie zur sozialen Koh{\"a}sion zwischen diversen Kulturen beitragen. Daher wurde gepr{\"u}ft, ob und inwiefern die negativ konnotierte ethnozentrische Wahrnehmung von „Differenz" (Bielefeld, 1998), die als soziales Konstrukt zwischen autochthonen und allochthonen Gruppen hergestellt wird, durch das Engagement der Vereinsakteure einen konstruktiven Wandel erf{\"a}hrt. {\"U}bergeordnetes Ziel all dieser Forschungsfragen war es, ein fundiertes Verst{\"a}ndnis {\"u}ber die Rolle von t{\"u}rkischen Fußballvereinen als soziale Mechanismen zu erlangen und deren Funktionsweise bei der Konstitution von Anpassungsstrategien in diesem sozialen Feld untersuchen. Detailliert wurde diese Rolle unter der Konzeptualisierung von sozialen Positionierungsmuster betrachtet, die als Gef{\"u}ge von Deutungen des Allt{\"a}glichen verstanden werden, das individuelle und kollektive Handlungsmuster und implizit Muster des Fremdverstehens sowie des othering im Migrationskontext reguliert. Eine Rekonstruktion der sozialen Positionierungsmuster bietet eine eingehende soziologische Untersuchung dieser Teilnehmergruppe, die zudem Aufschluss {\"u}ber die Bedeutung und das Verst{\"a}ndnis von ethnischer Zugeh{\"o}rigkeit f{\"u}r letztere gibt. Neben umfangreicher Feldbeobachtung wurden in dieser qualitativen Studie mit Spielern verschiedener Vereine insgesamt zehn Gruppendiskussionen (Bohnsack, 2004) innerhalb ihrer Mannschaften zu gemeinsamen allt{\"a}glichen Erlebnissen und Erfahrungen durchgef{\"u}hrt, aufgezeichnet und mittels sozialwissenschaftlichem hermeneutischem Verfahren (Soeffner, 2004) interpretiert.

The solar activity exhibits a cyclic behaviour with a period of about 11 years. The solar cycle properties are governed by the dynamo taking place in the interior of the Sun, and they are distinctive. Extending the knowledge about solar cycle properties into the past is essential for understanding the solar dynamo and forecasting space weather. It can be acquired through the analysis of historical sunspot drawings. Sunspots are the dark areas, which are associated with strong magnetic fields, on the solar surface. Sunspots are the oldest and longest available observed features of solar activity. One of the longest available records of sunspot drawings is the collection by Samuel Heinrich Schwabe during 1825-1867. The sunspot sizes measured from digitized Schwabe drawings are not to scale and need to be converted into physical sunspot areas. We employed a statistical approach assuming that the area distribution of sunspots was the same in the 19th century as it was in the 20th century. Umbral areas for about 130 000 sunspots observed by Schwabe were obtained. The annually averaged sunspot areas correlate reasonably well with the sunspot number. Tilt angles and polarity separations of sunspot groups were calculated assuming them to be bipolar. There is, of course, no polarity information in the observations. We derived an average tilt angle by attempting to exclude unipolar groups with a minimum separation of the two surmised polarities and an outlier rejection method, which follows the evolution of each group and detects the moment, when it turns unipolar as it decays. As a result, the tilt angles, although displaying considerable natural scatter, are on average 5.85° ± 0.25°, with the leading polarity located closer to the equator, in good agreement with tilt angles obtained from 20th century data sets. Sources of uncertainties in the tilt angle determination are discussed and need to be addressed whenever different data sets are combined. Digital images of observations printed in the books Rosa Ursina and Prodromus pro sole mobili by Christoph Scheiner, as well as the drawings from Scheiner's letters to Marcus Welser, are analyzed to obtain information on the positions and sizes of sunspots that appeared before the Maunder minimum. In most cases, the given orientation of the ecliptic is used to set up the heliographic coordinate system for the drawings. Positions and sizes are measured manually displaying the drawings on a computer screen. Very early drawings have no indication of the solar orientation. A rotational matching using common spots of adjacent days is used in some cases, while in other cases, the assumption that images were aligned with a zenith-horizon coordinate system appeared to be the most likely. In total, 8167 sunspots were measured. A distribution of sunspot latitudes versus time (butterfly diagram) is obtained for Scheiner's observations. The observations of 1611 are very inaccurate, but the drawings of 1612 have at least an indication of the solar orientation, while the remaining part of the spot positions from 1618-1631 have good to very good accuracy. We also computed 697 tilt angles of apparent bipolar sunspot groups, which were observed in the period 1618-1631. We find that the average tilt angle of nearly 4° does not significantly differ from the 20th century values. The solar cycle properties seem to be related to the tilt angles of sunspot groups, and it is an important parameter in the surface flux transport models. The tilt angles of bipolar sunspot groups from various historical sets of solar drawings including from Schwabe and Scheiner are analyzed. Data by Scheiner, Hevelius, Staudacher, Zucconi, Schwabe, and Spörer deliver a series of average tilt angles spanning a period of 270 years, in addition to previously found values for 20th-century data obtained by other authors. We find that the average tilt angles before the Maunder minimum were not significantly different from modern values. However, the average tilt angles of a period 50 years after the Maunder minimum, namely for cycles 0 and 1, were much lower and near zero. The typical tilt angles before the Maunder minimum suggest that abnormally low tilt angles were not responsible for driving the solar cycle into a grand minimum. With the Schwabe (1826-1867) and Spörer (1866-1880) sunspot data, the butterfly diagram of sunspot groups extends back till 1826. A recently developed method, which separates the wings of the butterfly diagram based on the long gaps present in sunspot group occurrences at different latitudinal bands, is used to separate the wings of the butterfly diagram. The cycle-to-cycle variation in the start (F), end (L), and highest (H) latitudes of the wings with respect to the strength of the wings are analyzed. On the whole, the wings of the stronger cycles tend to start at higher latitudes and have a greater extent. The time spans of the wings and the time difference between the wings in the northern hemisphere display a quasi-periodicity of 5-6 cycles. The average wing overlap is zero in the southern hemisphere, whereas it is 2-3 months in the north. A marginally significant oscillation of about 10 solar cycles is found in the asymmetry of the L latitudes. This latest, extended database of butterfly wings provides new observational constraints, regarding the spatio-temporal distribution of sunspot occurrences over the solar cycle, to solar dynamo models.}, language = {en} } @phdthesis{Paasche2018, author = {Paasche, Hendrik}, title = {Addressing uncertainty in geophysical parameter estimation}, school = {Universit{\"a}t Potsdam}, pages = {341}, year = {2018}, language = {en} } @phdthesis{Kruse2018, author = {Kruse, Sebastian}, title = {Scalable data profiling}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-412521}, school = {Universit{\"a}t Potsdam}, pages = {ii, 156}, year = {2018}, abstract = {Data profiling is the act of extracting structural metadata from datasets. Structural metadata, such as data dependencies and statistics, can support data management operations, such as data integration and data cleaning. Data management often is the most time-consuming activity in any data-related project. Its support is extremely valuable in our data-driven world, so that more time can be spent on the actual utilization of the data, e. g., building analytical models. In most scenarios, however, structural metadata is not given and must be extracted first. Therefore, efficient data profiling methods are highly desirable. Data profiling is a computationally expensive problem; in fact, most dependency discovery problems entail search spaces that grow exponentially in the number of attributes. To this end, this thesis introduces novel discovery algorithms for various types of data dependencies - namely inclusion dependencies, conditional inclusion dependencies, partial functional dependencies, and partial unique column combinations - that considerably improve over state-of-the-art algorithms in terms of efficiency and that scale to datasets that cannot be processed by existing algorithms. The key to those improvements are not only algorithmic innovations, such as novel pruning rules or traversal strategies, but also algorithm designs tailored for distributed execution. While distributed data profiling has been mostly neglected by previous works, it is a logical consequence on the face of recent hardware trends and the computational hardness of dependency discovery. To demonstrate the utility of data profiling for data management, this thesis furthermore presents Metacrate, a database for structural metadata. Its salient features are its flexible data model, the capability to integrate various kinds of structural metadata, and its rich metadata analytics library. We show how to perform a data anamnesis of unknown, complex datasets based on this technology. In particular, we describe in detail how to reconstruct the schemata and assess their quality as part of the data anamnesis.

The group of Prof. Nicolae Hurduc supports the model claiming that the cyclic isomerization of azobenzenes may cause an athermal transition of the glassy azobenzene containing polymer into a fluid state, the so-called photo-fluidization concept. This concept is quite convenient for an intuitive understanding of the deformation process as an anisotropic flow of the polymer material. The group of Prof. Svetlana Santer supports the re-orientational model where the mass-transport of the polymer material accomplished during polymer deformation is stated to be generated by the light-induced re-orientation of the azobenzene side chains and as a consequence of the polymer backbone that in turn results in local mechanical stress, which is enough to irreversibly deform an azobenzene containing material even in the glassy state. For the debate we chose three polymers differing in the glass transition temperature, 32 °C, 87 °C and 95 °C, representing extreme cases of flexible and rigid materials. Polymer film deformation occurring during irradiation with different interference patterns is recorded using a homemade set-up combining an optical part for the generation of interference patterns and an atomic force microscope for acquiring the kinetics of film deformation. We also demonstrated the unique behaviour of azobenzene containing polymeric films to switch the topography in situ and reversibly by changing the irradiation conditions. We discuss the results of reversible deformation of three polymers induced by irradiation with intensity (IIP) and polarization (PIP) interference patterns, and the light of homogeneous intensity in terms of two approaches: the re-orientational and the photo-fluidization concepts. Both agree in that the formation of opto-mechanically induced stresses is a necessary prerequisite for the process of deformation. Using this argument, the deformation process can be characterized either as a flow or mass transport.}, language = {en} } @misc{Scianna2018, author = {Scianna, Bastian Matteo}, title = {A blueprint for successful peacekeeping?}, series = {The International History Review}, journal = {The International History Review}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-412937}, pages = {24}, year = {2018}, abstract = {On 6 June 1982, Israel invaded Lebanon to fight the Palestinian Liberation Organization (PLO).

The prosocial versus egoistic intentions attributed to the idea presenter are proposed to mediate the latter effect. We conducted three scenario-based studies in which supervisors evaluated fictitious ideas voiced by employees that - if implemented - would have power-related consequences for them as a supervisor. Results show that the higher a supervisors' explicit power motive was, the less likely they were to support a power-threatening idea (Study 1, N = 60). Moreover, idea support was less likely when this idea was proposed by an employee that was described as high (rather than low) on power motivation (Study 2, N = 79); attributed prosocial intentions mediated this effect.

It reduces the risk of changing their software and allows them to manage different configurations and to collaborate with others more efficiently. This is amplified by code sharing platforms such as GitHub or Bitbucket. Most version control systems track files (e.g., Git, Mercurial, and Subversion do), but some programming environments do not operate on files, but on objects instead (many Smalltalk implementations do). Users of such environments want to use version control for their objects anyway. Specialized version control systems, such as the ones available for Smalltalk systems (e.g., ENVY/Developer and Monticello), focus on a small subset of objects that can be versioned. Most of these systems concentrate on the tracking of methods, classes, and configurations of these. Other user-defined and user-built objects are either not eligible for version control at all, tracking them involves complicated workarounds, or a fixed, domain-unspecific serialization format is used that does not equally suit all kinds of objects. Moreover, these version control systems that are specific to a programming environment require their own code sharing platforms; popular, well-established platforms for file-based version control systems cannot be used or adapter solutions need to be implemented and maintained. To improve the situation for version control of arbitrary objects, a framework for tracking, converting, and storing of objects is presented in this report. It allows editions of objects to be stored in an exchangeable, existing backend version control system. The platforms of the backend version control system can thus be reused. Users and objects have control over how objects are captured for the purpose of version control. Domain-specific requirements can be implemented. The storage format (i.e. the file format, when file-based backend version control systems are used) can also vary from one object to another. Different editions of objects can be compared and sets of changes can be applied to graphs of objects. A generic way for capturing and restoring that supports most kinds of objects is described. It models each object as a collection of slots. Thus, users can begin to track their objects without first having to implement version control supplements for their own kinds of objects. The proposed architecture is evaluated using a prototype implementation that can be used to track objects in Squeak/Smalltalk with Git. The prototype improves the suboptimal standing of user objects with respect to version control described above and also simplifies some version control tasks for classes and methods as well. It also raises new problems, which are discussed in this report as well.}, language = {en} } @techreport{Verlaan2018, type = {Working Paper}, author = {Verlaan, Stephanie}, title = {Male victims of wartime sexual violence: an ignored phenomenon}, series = {Staat, Recht und Politik - Forschungs- und Diskussionspapiere}, journal = {Staat, Recht und Politik - Forschungs- und Diskussionspapiere}, number = {6}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {2509-6974}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-412632}, pages = {13}, year = {2018}, abstract = {The phenomenon of male-to-male sexual assault undoubtedly occurs, both in domestic and conflict contexts.

The strength with which the feminist discourse has embedded itself into the agendas of relevant actors is obstructing attempts at unbiased analysis of gender-based violence and the development of a discourse dedicated to understanding male sexual assault. It appears to be a prevailing sector-wide perception that females are the only victims of sexual violence and that creating space for a discussion on male-sexual assault will detract worth from the feminist discourse on female sexual assault.

Further, their use as carrier for controlled release purposes was explored. Polyzwitterion-based block copolymers were synthesized by atom transfer radical polymerization (ATRP) via a macroinitiator approach with varied molar masses and co-monomer contents.

Their (co)polymers were characterized with respect to their molecular structure by proton nuclear magnetic resonance (1H-NMR) and gel permeation chromatography (GPC). Their phase behaviors in pure water as well as in physiological saline were studied by turbidimetry and dynamic light scattering (DLS). These (co)polymers are thermoresponsive with UCST-type phase behavior in aqueous solution. Their phase transition temperatures depend strongly on the molar masses and the incorporation of co-monomers: phase transition temperatures increased with increasing molar masses and content of poorly water-soluble co-monomer. In addition, the presence of salt influenced the phase transition dramatically. The phase transition temperature decreased with increasing salt content in the solution. While the PSPE homopolymers show a phase transition only in pure water, the PZPE homopolymers are able to exhibit a phase transition only in high salinity, as in physiological saline. Although both polyzwitterions have similar chemical structures that differ only in the anionic group (sulfonate group in SPE and sulfate group in ZPE), the water solubility is very different. Therefore, the phase transition temperatures of targeted block copolymers were modulated by using statistical copolymer of SPE and ZPE as thermoresponsive block, and varying the ratio of SPE to ZPE. Indeed, the statistical copolymers of P(SPE-co-ZPE) show phase transitions both in pure water as well as in physiological saline. Surprisingly, it was found that mPEG-b-PSBE block copolymer can display "schizophrenic" behavior in pure water, with the UCST-type cloud point occurring at lower temperature than the LCST-type one. The block copolymer, which satisfied best the boundary conditions, is block copolymer mPEG114-b-P(SPE43-co-ZPE39) with a cloud point of 45°C in physiological saline. Therefore, it was chosen for solubilization studies of several solvatochromic dyes as models of active agents, using the thermoresponsive block copolymer as "smart" carrier. The uptake and release of the dyes were explored by UV-Vis and fluorescence spectroscopy, following the shift of the wavelength of the absorbance or emission maxima at low and high temperature. These are representative for the loaded and released state, respectively. However, no UCST-transition triggered uptake and release of these dyes could be observed. Possibly, the poor affinity of the polybetaines to the dyes in aqueous environtments may be related to the widely reported antifouling properties of zwitterionic polymers.}, language = {en} } @phdthesis{Markmann2018, author = {Markmann, Friedrich}, title = {Lokale Leistungserbringung im kommunalen Interesse}, series = {Kommunalrechtliche Studien ; 6}, journal = {Kommunalrechtliche Studien ; 6}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {978-3-8487-4929-4}, school = {Universit{\"a}t Potsdam}, pages = {239}, year = {2018}, abstract = {Genossenschaften haben wieder Konjunktur.

In dieser Arbeit wurde das Schwingungsverhalten von Streichinstrumenten durch den Einsatz minimal-invasiver piezoelektrischer Polymerfilmsensoren untersucht. Die studierten Kopplungsph{\"a}nomene umfassen den sogenannten Wolfton und Schwingungstilger, die zu dessen Abschw{\"a}chung verwendet werden, sowie die gegenseitige Beeinflussung von Bogen und Instrument beim Spielvorgang. An Dielektrischen Elastomeraktormembranen wurde dagegen der Einfluss der elastischen Eigenschaften des Membranmaterials auf das akustische und elektromechanische Schwingungsverhalten gezeigt. Die Dissertation gliedert sich in drei Teile, deren wesentliche Ergebnisse im Folgenden zusammengefasst werden. In Teil I wurde die Funktionsweise eines abstimmbaren Schwingungstilgers zur D{\"a}mpfung von Wolft{\"o}nen auf Streichinstrumenten untersucht. Durch Abstimmung der Resonanzfrequenz des Schwingungstilgers auf die Wolftonfrequenz kann ein Teil der Saitenschwingungen absorbiert werden, so dass die zu starke Anregung der Korpusresonanz vermieden wird, die den Wolfton verursacht. Der Schwingungstilger besteht aus einem „Wolft{\"o}ter", einem Massest{\"u}ck, welches auf der Nachl{\"a}nge der betroffenen Saite (zwischen Steg und Saitenhalter) installiert wird. Hier wurde gezeigt, wie die Resonanzen dieses Schwingungstilgers von der Masse des Wolft{\"o}ters und von dessen Position auf der Nachl{\"a}nge abh{\"a}ngen. Aber auch die Geometrie des Wolft{\"o}ters stellte sich als ausschlaggebend heraus, insbesondere bei einem nicht-rotationssymmetrischen Wolft{\"o}ter: In diesem Fall entsteht - basierend auf den zu erwartenden nicht-harmonischen Moden einer massebelasteten Saite - eine zus{\"a}tzliche Mode, die von der Polarisationsrichtung der Saitenschwingung abh{\"a}ngt. Teil II der Dissertation befasst sich mit Elastomermembranen, die als Basis von Dielektrischen Elastomeraktoren dienen, und die wegen der Membranspannung auch akustische Resonanzen aufweisen. Die Ansprache von Elastomeraktoren h{\"a}ngt unter anderem von der Geschwindigkeit der elektrischen Anregung ab. Die damit zusammenh{\"a}ngenden viskoelastischen Eigenschaften der hier verwendeten Elastomere, Silikon und Acrylat, wurden einerseits in einer frequenzabh{\"a}ngigen dynamisch-mechanischen Analyse des Elastomers erfasst, andererseits auch optisch an vollst{\"a}ndigen Aktoren selbst gemessen. Die h{\"o}here Viskosit{\"a}t des Acrylats, das bei tieferen Frequenzen h{\"o}here Aktuationsdehnungen als das Silikon zeigt, f{\"u}hrt zu einer Verminderung der Dehnungen bei h{\"o}heren Frequenzen, so dass {\"u}ber etwa 40 Hertz mit Silikon gr{\"o}ßere Aktuationsdehnungen erreicht werden. Mit den untersuchten Aktoren konnte die Gitterkonstante weicher optischer Beugungsgitter kontrolliert werden, die als zus{\"a}tzlicher Film auf der Membran installiert wurden. {\"U}ber eine Messung der akustischen Resonanzfrequenz von Elastomermebranen aus Acrylat in 1Abh{\"a}ngigkeit von ihrer Vorstreckung konnte in Verbindung mit einer Modellierung des hyperelastischen Verhaltens des Elastomers (Ogden-Modell) der Schermodul bestimmt werden. Schließlich wird in Teil III die Untersuchung von Geigen und ihrer Streichanregung mit Hilfe minimal-invasiver piezoelektrischer Polymerfilme geschildert. Es konnten am Bogen und am Steg von Geigen - unter den beiden F{\"u}ßen des Stegs - jeweils zwei Filmsensoren installiert werden. Mit den beiden Sensoren am Steg wurden Frequenzg{\"a}nge von Geigen gemessen, welche eine Bestimmung der frequenzabh{\"a}ngigen Stegbewegung erlaubten. Diese Methode erm{\"o}glicht damit auch eine umfassende Charakterisierung der Signaturmoden in Bezug auf die Stegdynamik. Die Ergebnisse der komplement{\"a}ren Methoden von Impulsanregung und nat{\"u}rlichem Spielen der Geigen konnten dank der Sensoren verglichen werden. F{\"u}r die Nutzung der Sensoren am Bogen - insbesondere f{\"u}r eine Messung des Bogendrucks - wurde eine Kalibrierung des Bogen-Sensor-Systems mit Hilfe einer Materialpr{\"u}fmaschine durchgef{\"u}hrt. Bei einer Messung w{\"a}hrend des nat{\"u}rlichen Spielens wurde mit den Sensoren am Bogen einerseits die {\"U}bertragung der Saitenschwingung auf den Bogen festgestellt. Dabei konnten außerdem longitudinale Bogenhaarresonanzen identifiziert werden, die von der Position der Saite auf dem Bogen abh{\"a}ngen. Aus der Analyse dieses Ph{\"a}nomens konnte die longitudinale Wellengeschwindigkeit der Bogenhaare bestimmt werden, die eine wichtige Gr{\"o}ße f{\"u}r die Kopplung zwischen Saite und Bogen ist. Mit Hilfe des Systems aus Sensoren an Bogen und Steg werden auf Grundlage der vorliegenden Arbeit Studien an Streichinstrumenten vorgeschlagen, in denen die Bespielbarkeit der Instrumente zu den jeweils angeregten Steg- und Bogenschwingungen in Beziehung gesetzt werden kann.

The composite electrode was fabricated from Kraft lignin and conductive carbon and the charge storage contribution was determined in terms of electrical double layer (EDL) and redox reactions. The important factors at play for achieving high faradaic charge storage capacity contribute to high surface area, accessibility of redox sites in lignin and their interaction with conductive additives. A thinner layer of lignin covering the high surface area of carbon facilitates the electron transfer process with a shorter pathway from the active sites of nonconductive lignin to the current collector leading to the improvement of faradaic charge storage capacity. Composite electrodes from lignin and carbon would be even more sustainable if the fluorinated binder can be omitted. A new route to fabricate a binder-free composite electrode from Kraft lignin and high surface area carbon has been proposed by crosslinking lignin with glyoxal. A high molecular weight of lignin is obtained to enhance both electroactivity and binder capability in composite electrodes. The order of the processing step of crosslinking lignin on the composite electrode plays a crucial role in achieving a stable electrode and high charge storage capacity. The crosslinked lignin based electrodes are promising since they allow for more stable, sustainable, halogen-free and environmentally benign devices for energy storage applications. Furthermore, improvement of the amount of redox active groups (quinone groups) in lignin is useful to enhance the capacity in lithium battery applications. Direct oxidative demethylation by cerium ammonium nitrate has been carried out under mild conditions. This proves that an increase of quinone groups is able to enhance the performance of lithium battery. Thus, lignin is a promising material and could be a good candidate for application in sustainable energy storage devices.}, language = {en} } @article{Dornfeldt2018, author = {Dornfeldt, Matthias}, title = {Oslo zwischen Berlin und Moskau}, series = {Welt-Trends : das außenpolitische Journal}, volume = {26}, journal = {Welt-Trends : das außenpolitische Journal}, number = {140}, publisher = {WeltTrends}, address = {Potsdam}, isbn = {978-3-945878-85-9}, issn = {0944-8101}, pages = {40 -- 44}, year = {2018}, language = {de} } @phdthesis{Warner2018, author = {Warner, Greta J.}, title = {Personal initiative in childhood and early adolescence}, school = {Universit{\"a}t Potsdam}, pages = {235}, year = {2018}, language = {en} } @phdthesis{Jurewicz2018, author = {Jurewicz, Grażyna}, title = {Moses Mendelssohn {\"u}ber die Bestimmung des Menschen}, publisher = {Wehrhahn}, address = {Hannover}, isbn = {978-3-86525-632-4}, school = {Universit{\"a}t Potsdam}, pages = {244}, year = {2018}, abstract = {Die Lebensgeschichte des j{\"u}dischen Gelehrten und Aufkl{\"a}rers Moses Mendelssohn (1729-1786), der allen Hindernissen zum Trotz in den Rang einer allseits anerkannten intellektuellen Autorit{\"a}t aufstieg, wurde innerhalb der Geschichte des deutschen Judentums zum Inbegriff einer individuellen Emanzipation im Medium der Bildung.

In the present pilot study, we investigated whether repetitive conditioning hops can also increase reactive jump and sprint performance in sprint-trained elite athletes competing at an international level. Methods: Jump and sprint performances of 5 athletes were randomly assessed under 2 conditions. The control condition (CON) comprised 8 DJs and 4 trials of 30-m sprints. The intervention condition (HOP) consisted of 10 maximal repetitive two-legged hops that were conducted 10 s prior to each single DJ and sprint trial. DJ performance was analyzed using a one-dimensional ground reaction force plate. Step length (SL), contact time (CT), and sprint time (ST) during the 30-m sprints were recorded using an opto-electronic measurement system. Results: Following the conditioning activity, DJ height and external DJ peak power were both significantly increased by 11 \% compared to the control condition. All other variables did not show any significant differences between HOP and CON. Conclusions: In the present pilot study, we were able to demonstrate large improvements in DJ performance even in sprint-trained elite athletes following a conditioning activity consisting of maximal two-legged repetitive hops. This strengthens the hypothesis that plyometric conditioning exercises can induce performance enhancements in elite athletes that are even greater than those observed in recreationally active athletes.. In addition, it appears that the transfer of these effects to other stretch-shortening cycle activities is limited, as we did not observe any changes in sprint performance following the plyometric conditioning activity.}, language = {en} } @misc{WippertWiebking2018, author = {Wippert, Pia-Maria and Wiebking, Christine}, title = {Stress and Alterations in the Pain Matrix}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {438}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-412058}, pages = {11}, year = {2018}, abstract = {The genesis of chronic pain is explained by a biopsychosocial model.

Some studies report good tone discrimination abilities for all tested age groups, others report decreased or enhanced discrimination with increasing age, and still others report U-shaped developmental curves. Since prior studies have used a wide range of contrasts and experimental procedures, it is unclear how specific task requirements interact with discrimination abilities at different ages. In the present work, we tested German and Cantonese adults on their discrimination of Cantonese lexical tones, as well as German-learning infants between 6 and 18 months of age on their discrimination of two specific Cantonese tones using two different types of experimental procedures. The adult experiment showed that German native speakers can discriminate between lexical tones, but native Cantonese speakers show significantly better performance. The results from German-learning infants suggest that 6- and 18-month-olds discriminate tones, while 9-month-olds do not, supporting a U-shaped developmental curve. Furthermore, our results revealed an effect of methodology, with good discrimination performance at 6 months after habituation but not after familiarization. These results support three main conclusions. First, habituation can be a more sensitive procedure for measuring infants' discrimination than familiarization. Second, the previous finding of a U-shaped curve in the discrimination of lexical tones is further supported. Third, discrimination abilities at 18 months appear to reflect mature perceptual sensitivity to lexical tones, since German adults also discriminated the lexical tones with high accuracy.}, language = {en} }
