The first article examines how recent changes in the governance of employment services in three European countries (Denmark, Germany and Norway) have influenced accountability relationships from a very wide-ranging perspective. It starts from the overall assumption in the literature that accountability relationships are becoming more numerous and complex, and that these changes may lead to multiple accountability disorder. The article explores these assumptions by analyzing the different actors involved and the information requested in the new governance arrangements in all three countries. It concludes that the considerable changes in organizational arrangements and more managerial information demanded and provided have led to more shared forms of accountability. Nevertheless, a clear development towards less political or administrative accountability could not be observed. The second article analyzes how the structure and development of reform processes affect accountability relationships and via what mechanisms. It is distinguished between an instrumental perspective and an institutional perspective and each of these perspectives takes a different view on the link between reforms and concrete action and results. By taking the welfare reforms in Norway and Germany as an example, it is shown that the reform outcomes in both countries are the result of a complex process of powering, puzzling and institutional constraints where different situational interpretations of problems, interests and administrative legacies had to be balanced. Accountability thus results not from a single process of environmental necessity or strategic choice, but from a dynamic interplay between different actors and institutional spheres. The third article then covers a specific instrument of public sector reforms, i.e. the increasing use of performance management. The article discusses the challenges and ambiguities between performance management and different forms of accountability based on the cases of the reformed welfare administration in Norway and Germany. The findings are that the introduction of performance management creates new accountability structures which influence service delivery, but not necessarily in the direction expected by reform agents. Observed unintended consequences include target fixation, the displacement of political accountability and the predominance of control aspects of accountability. The fourth article analyzes the accountability implications of the increasingly marketized models of welfare governance. It has often been argued that relocating powers and discretion to private contractors involve a trade-off between democratic accountability and efficiency. However, there is limited empirical evidence of how contracting out shapes accountability or is shaped by alternative democratic or administrative forms of accountability. Along these lines the article examines employment service accountability in the era of contracting out in Germany, Denmark and Great Britain. It is found that market accountability instruments are complementary instruments, not substitutes. The findings highlight the importance of administrative and political instruments in legitimizing marketized service provision and shed light on the processes that lead to the development of a hybrid accountability model. The fifth and sixth articles focus on the diagonal accountability relationships between public agencies, supreme audit institutions (SAI) and parental ministry or parliament. The fifth article examines the evolving role of SAIs in Denmark, Germany and Norway focusing particularly on their contribution to public accountability and their ambivalent relationship with some aspects of public sector reform in the welfare sector. The article analyzes how SAIs assess New Public Management inspired reforms in the welfare sector in the three countries. The analysis shows that all three SAIs have taken on an evaluative role when judging New Public Management instruments. At the same time their emphasis on legality and compliance can be at odds with some of the operating principles introduced by New Public Management reforms. The sixth article focuses on the auditing activities of the German SAI in the field of labor market administration as a single in-depth case study. The purpose is to analyze how SAIs gain impact in diagonal accountability settings. The results show that the direct relationship between auditor and auditee based on cooperation and trust is of outstanding importance for SAIs to give effect to their recommendations. However, if an SAI has to rely on actors of diagonal accountability, it is in a vulnerable position as it might lose control over the interpretation of its results.}, language = {en} } @unpublished{LyTarkhanov2015, author = {Ly, Ibrahim and Tarkhanov, Nikolai Nikolaevich}, title = {Asymptotic expansions at nonsymmetric cuspidal points}, volume = {4}, number = {7}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {2193-6943}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-78199}, pages = {11}, year = {2015}, abstract = {We study asymptotics of solutions to the Dirichlet problem in a domain whose boundary contains a nonsymmetric conical point.

I focus on the observation of coherent phonon propagation by time resolved Brillouin scattering: following the excition of metal transducer films with a femtosecond infrared pump pulse, coherent phonon dynamics in the GHz frequency range are triggered. Their propagation is monitored using a delayed white light probe pulse. The technique is illustrated on various thin films and multilayered samples. I apply the technique to investigate the linear and nonlinear acoustic response in bulk SrTiO_3, which displays a ferroelastic phase transition from a cubic to a tetragonal structural phase at T_a=105 K. In the linear regime, I observe a coupling of the observed acoustic phonon mode to the softening optic modes describing the phase transition. In the nonlinear regime, I find a giant slowing down of the sound velocity in the low temperature phase that is only observable for a strain amplitude exceeding the tetragonality of the material. It is attributed to a coupling of the high frequency phonons to ferroelastic domain walls in the material. I propose a new mechanism for the coupling of strain waves to the domain walls that is only effective for high amplitude strain. A detailed study of the phonon attenuation across a wide temperature range shows that the phonon attenuation at low temperatures is influenced by the domain configuration, which is determined by interface strain. Preliminary measurements on magnetic-ferroelectric multilayers reveal that the excitation fluence needs to be carefully controlled when dynamics at phase transitions are studied.}, language = {en} } @phdthesis{Rohrmann2015, author = {Rohrmann, Alexander}, title = {The role of wind and water in shaping earth's plateaus}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77938}, school = {Universit{\"a}t Potsdam}, pages = {XXV, 157}, year = {2015}, abstract = {The overarching goal of this dissertation is to provide a better understanding of the role of wind and water in shaping Earth's Cenozoic orogenic plateaus - prominent high-elevation, low relief sectors in the interior of Cenozoic mountain belts. In particular, the feedbacks between surface uplift, the build-up of topography and ensuing changes in precipitation, erosion, and vegetation patterns are addressed in light of past and future climate change. Regionally, the study focuses on the two world's largest plateaus, the Altiplano-Puna Plateau of the Andes and Tibetan Plateau, both characterized by average elevations of >4 km. Both plateaus feature high, deeply incised flanks with pronounced gradients in rainfall, vegetation, hydrology, and surface processes. These characteristics are rooted in the role of plateaus to act as efficient orographic barriers to rainfall and to force changes in atmospheric flow. The thesis examines the complex topics of tectonic and climatic forcing of the surface-process regime on three different spatial and temporal scales: (1) bedrock wind-erosion rates are quantified in the arid Qaidam Basin of NW Tibet over millennial timescales using cosmogenic radionuclide dating; (2) present-day stable isotope composition in rainfall is examined across the south-central Andes in three transects between 22° S and 28° S; these data are modeled and assessed with remotely sensed rainfall data of the Tropical Rainfall Measuring Mission and the Moderate Resolution Imaging Spectroradiometer; (3) finally, a 2.5-km-long Mio-Pliocene sedimentary record of the intermontane Angastaco Basin (25°45' S, 66°00' W) is presented in the context of hydrogen and carbon compositions of molecular lipid biomarker, and oxygen and carbon isotopes obtained from pedogenic carbonates; these records are compared to other environmental proxies, including hydrated volcanic glass shards from volcanic ashes intercalated in the sedimentary strata. There are few quantitative estimates of eolian bedrock-removal rates from arid, low relief landscapes. Wind-erosion rates from the western Qaidam Basin based on cosmogenic 10Be measurements document erosion rates between 0.05 to 0.4 mm/yr. This finding indicates that in arid environments with strong winds, hyperaridity, exposure of friable strata, and ongoing rock deformation and uplift, wind erosion can outpace fluvial erosion. Large eroded sediment volumes within the Qaidam Basin and coeval dust deposition on the Chinese Loess plateau, exemplify the importance of dust production within arid plateau environments for marine and terrestrial depositional processes, but also health issues and fertilization of soils. In the south-central Andes, the analysis of 234 stream-water samples for oxygen and hydrogen reveals that areas experiencing deep convective storms do not show the commonly observed patterns of isotopic fractionation and the expected co-varying relationships between oxygen and hydrogen with increasing elevation. These convective storms are formed over semi-arid intermontane basins in the transition between the broken foreland of the Sierras Pampeanas, the Eastern Cordillera, and the Puna Plateau in the interior of the orogen. Here, convective rainfall dominates the precipitation budget and no systematic stable isotope-elevation relationship exists. Regions to the north, in the transition between the broken foreland and the Subandean foreland fold-and-thrust belt, the impact of convection is subdued, with lower degrees of storminess and a stronger expected isotope-elevation relationship. This finding of present-day fractionation trends of meteoric water is of great importance for paleoenvironmental studies in attempts to use stable isotope relationships in the reconstruction of paleoelevations. The third part of the thesis focuses on the paleohydrological characteristics of the Mio-Pliocene (10-2 Ma) Angastaco Basin sedimentary record, which reveals far-reaching environmental changes during Andean uplift and orographic barrier formation. A precipitation- evapotranspiration record identifies the onset of a precipitation regime related to the South American Low Level Jet at this latitude after 9 Ma. Humid foreland conditions existed until 7 Ma, followed by orographic barrier uplift to the east of the present-day Angastaco Basin. This was superseded by rapid (~0.5 Myr) aridification in an intermontane basin, highlighting the effects of eastward-directed deformation. A transition in vegetation cover from a humid C3 forest ecosystem to semi-arid C4-dominated vegetation was coeval with continued basin uplift to modern elevations.}, language = {en} } @phdthesis{Niedl2015, author = {Niedl, Robert Raimund}, title = {Nichtlineare Kinetik und responsive Hydrogele f{\"u}r papierbasierte Schnelltestanwendungen}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77735}, school = {Universit{\"a}t Potsdam}, pages = {iv, 128}, year = {2015}, abstract = {Viele klinische Schnelltestsysteme ben{\"o}tigen vorpr{\"a}parierte oder aufgereinigte Analyte mit frisch hergestellten L{\"o}sungen.

Besides industrialization, agriculture is a major driver of global change. This change in turn impairs the agriculture sector, reducing crop yields namely due to soil degradation, water scarcity, and climate change. However, this is a more complex issue than it appears. Crop yields can be increased by use of agrochemicals and fertilizers which are mainly produced by fossil energy. This is important to meet the increasing food demand driven by global demographic change, which is further accelerated by changes in regional lifestyles. In this dissertation, we attempt to address this complex problem exploring agricultural potential globally but on a local scale. For this, we considered the influence of lifestyle changes (dietary patterns) as well as technological progress and their effects on climate change, mainly greenhouse gas (GHG) emissions. Furthermore, we examined options for optimizing crop yields in the current cultivated land with the current cropping patterns by closing yield gaps. Using this, we investigated in a five-minute resolution the extent to which food demand can be met locally, and/or by regional and/or global trade. Globally, food consumption habits are shifting towards calorie rich diets. Due to dietary shifts combined with population growth, the global food demand is expected to increase by 60-110\% between 2005 and 2050. Hence, one of the challenges to global sustainability is to meet the growing food demand, while at the same time, reducing agricultural inputs and environmental consequences. In order to address the above problem, we used several freely available datasets and applied multiple interconnected analytical approaches that include artificial neural network, scenario analysis, data aggregation and harmonization, downscaling algorithm, and cross-scale analysis. Globally, we identified sixteen dietary patterns between 1961 and 2007 with food intakes ranging from 1,870 to 3,400 kcal/cap/day. These dietary patterns also reflected changing dietary habits to meat rich diets worldwide. Due to the large share of animal products, very high calorie diets that are common in the developed world, exhibit high total per capita emissions of 3.7-6.1 kg CO2eq./day. This is higher than total per capita emissions of 1.4-4.5 kg CO2eq./day associated with low and moderate calorie diets that are common in developing countries. Currently, 40\% of the global crop calories are fed to livestock and the feed calorie use is four times the produced animal calories. However, these values vary from less than 1 kcal to greater 10 kcal around the world. On the local and national scale, we found that the local and national food production could meet demand of 1.9 and 4.4 billion people in 2000, respectively. However, 1 billion people from Asia and Africa require intercontinental agricultural trade to meet their food demand. Nevertheless, these regions can become food self-sufficient by closing yield gaps that require location specific inputs and agricultural management strategies. Such strategies include: fertilizers, pesticides, soil and land improvement, management targeted on mitigating climate induced yield variability, and improving market accessibility. However, closing yield gaps in particular requires global N-fertilizer application to increase by 45-73\%, P2O5 by 22-46\%, and K2O by 2-3 times compare to 2010. Considering population growth, we found that the global agricultural GHG emissions will approach 7 Gt CO2eq./yr by 2050, while the global livestock feed demand will remain similar to 2000. This changes tremendously when diet shifts are also taken into account, resulting in GHG emissions of 20 Gt CO2eq./yr and an increase of 1.3 times in the crop-based feed demand between 2000 and 2050. However, when population growth, diet shifts, and technological progress by 2050 were considered, GHG emissions can be reduced to 14 Gt CO2eq./yr and the feed demand to nearly 1.8 times compare to that in 2000. Additionally, our findings shows that based on the progress made in closing yield gaps, the number of people depending on international trade can vary between 1.5 and 6 billion by 2050. In medium term, this requires additional fossil energy. Furthermore, climate change, affecting crop yields, will increase the need for international agricultural trade by 4\% to 16\%. In summary, three general conclusions are drawn from this dissertation. First, changing dietary patterns will significantly increase crop demand, agricultural GHG emissions, and international food trade in the future when compared to population growth only. Second, such increments can be reduced by technology transfer and technological progress that will enhance crop yields, decrease agricultural emission intensities, and increase livestock feed conversion efficiencies. Moreover, international trade dependency can be lowered by consuming local and regional food products, by producing diverse types of food, and by closing yield gaps. Third, location specific inputs and management options are required to close yield gaps. Sustainability of such inputs and management largely depends on which options are chosen and how they are implemented. However, while every cultivated land may not need to attain its potential yields to enable food security, closing yield gaps only may not be enough to achieve food self-sufficiency in some regions. Hence, a combination of sustainable implementations of agricultural intensification, expansion, and trade as well as shifting dietary habits towards a lower share of animal products is required to feed the growing population.}, language = {en} } @misc{Kuntzsch2015, type = {Master Thesis}, author = {Kuntzsch, Christian}, title = {Konzeption und Implementierung eines multimodalen Campusroutenplaners am Beispiel der Universit{\"a}t Potsdam}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77467}, school = {Universit{\"a}t Potsdam}, pages = {XIV, 86}, year = {2015}, abstract = {Die regelm{\"a}ßige Navigation durch den Raum geh{\"o}rt f{\"u}r Studenten der Universit{\"a}t Potsdam zum Alltag.

Cell walls have been a prominent area of research for a long time, but the chemical complexity and diversity of cell walls not just between species, but also within plants, between cell-types, and between cell wall micro-domains pose several challenges. Progress accelerated several-fold in cell wall biology owing to advances in sequencing technology, aided soon thereafter by advances in omics and imaging technologies. This development provides additional perspectives of cell walls across a rapidly growing number of species, highlighting a myriad of architectures, compositions, and functions. Furthermore, rather than the component centric view, integrative analysis of the different cell wall components across system-levels help to gain a more in-depth understanding of the structure and biosynthesis of the cell envelope and its interactions with the environment. To this end, in this work three case studies are detailed, all pertaining to the integrative analysis of heterogeneous cell wall related data arising from different system-levels and analytical techniques. A detailed account of multiblock methods is provided and in particular canonical correlation and regression methods of data integration are discussed. In the first integrative analysis, by employing canonical correlation analysis - a multivariate statistical technique to study the association between two datasets - novel insight to the relationship between glycans and phenotypic traits is gained. In addition, sparse partial least squares regression approach that adapts Lasso penalization and allows for the selection of a subset of variables was employed. The second case study focuses on an integrative analysis of images obtained from different spectroscopic techniques. By employing yet another multiblock approach - multiple co-inertia analysis, insitu biochemical composition of cell walls from different cell-types is studied thereby highlighting the common and complementary parts of the two hyperspectral imaging techniques. Finally, the third integrative analysis facilitates gene expression analysis of the Arabidopsis root transcriptome and translatome for the identification of cell wall related genes and compare expression patterns of cell wall synthesis genes. The computational analysis considered correlation and variation of expression across cell-types at both system-levels, and also provides insight into the degree of co-regulatory relationships that are preserved between the two processes. The integrative analysis of glycan data and phenotypic traits in cotton fibers using canonical methods led to the identification of specific polysaccharides which may play a major role during fiber development for the final fiber characteristics. Furthermore, this analysis provides a base for future studies on glycan arrays in case of developing cotton fibers. The integrative analysis of images from infrared and Raman spectroscopic approaches allowed the coupling of different analytical techniques to characterize complex biological material, thereby, representing various facets of their chemical properties. Moreover, the results from the co-inertia analysis demonstrated that the study was well adapted as it is relevant for coupling data tables in a symmetric way. Several indicators are proposed to investigate how the global and block scores are related. In addition, studying the root cells of \textit{Arabidopsis thaliana} allowed positing a novel pipeline to systematically investigate and integrate the different levels of information available at the global and single-cell level. The conducted analysis also confirms that previously identified key transcriptional activators of secondary cell wall development display highly conserved patterns of transcription and translation across the investigated cell-types. Moreover, the biological processes that display conserved and divergent patterns based on the cell-type-specific expression and translation levels are identified.}, language = {en} } @article{Denz2015, author = {Denz, Rebekka}, title = {Fragen und Antworten zu Gott und den Menschen}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77388}, pages = {145 -- 163}, year = {2015}, language = {de} } @article{MuellerSowa2015, author = {M{\"u}ller, Monika and Sowa, Oliver}, title = {Ein Blick hinter die Schult{\"u}re?}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77357}, pages = {135 -- 143}, year = {2015}, language = {de} } @article{Rudolf2015, author = {Rudolf, Gabi}, title = {„Sechzehn Gulden zwanzig Kreuzer"}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77348}, pages = {127 -- 133}, year = {2015}, language = {de} } @article{MuellerRudolf2015, author = {M{\"u}ller, Monika and Rudolf, Gabi}, title = {Tabakt{\"u}ten und Zigarettenschachteln}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77334}, pages = {109 -- 124}, year = {2015}, language = {de} } @article{Sowa2015, author = {Sowa, Oliver}, title = {„Teuerste Altern"}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77322}, pages = {103 -- 108}, year = {2015}, language = {de} } @article{MuellerRudolf2015, author = {M{\"u}ller, Monika and Rudolf, Gabi}, title = {Von t{\"o}dlichen Krankheiten, Totgeburten und Mania Stupita}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77317}, pages = {95 -- 101}, year = {2015}, language = {de} } @article{SingerBrehm2015, author = {Singer-Brehm, Elisabeth}, title = {Historie von der Sch{\"o}nen Melusina}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77302}, pages = {85 -- 93}, year = {2015}, language = {de} } @article{Sowa2015, author = {Sowa, Oliver}, title = {Lateinische Drucke in der Genisa Veitsh{\"o}chheim}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77290}, pages = {61 -- 82}, year = {2015}, language = {de} } @article{Stellmacher2015, author = {Stellmacher, Martha}, title = {Das Antlitz der Tora empfangen}, series = {Genisa-Bl{\"a}tter}, journal = {Genisa-Bl{\"a}tter}, editor = {Denz, Rebekka and Rudolf, Gabi}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-77283}, pages = {45 -- 59}, year = {2015}, language = {de} } @phdthesis{Duemke2015, author = {D{\"u}mke, Christian}, title = {Daseinsvorsorge, Wettbewerb und kommunale Selbstverwaltung im Bereich der liberalisierten Energiewirtschaft}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-314-5}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-73914}, school = {Universit{\"a}t Potsdam}, pages = {175}, year = {2015}, abstract = {Die Arbeit befasst sich zun{\"a}chst mit der Analyse und Einordnung des Begriffs der Daseinsvorsorge und deren Erbringung durch den Staat.

Zerovalent iron (ZVI) is highly reactive with chlorinated hydrocarbons (CHCs) and renders them into less harmful substances. Application of nZVI instead of granular ZVI can increase rates of dechlorination of CHCs by orders of magnitude, due to its higher surface area. This approach is still difficult to apply due to fast agglomeration and sedimentation of colloidal suspensions of nZVI, which leads to very short transport distances. To overcome this issue of limited mobility, polyanionic stabilisers are added to increase surface charge and stability of suspensions. In field experiments maximum transport distances of a few metres were achieved. A new approach, which is investigated in this thesis, is enhanced mobility of nZVI by a more mobile carrier colloid. The investigated composite material consists of activated carbon, which is loaded with nZVI. In this cumulative thesis, transport characteristics of carbon-colloid supported nZVI (c-nZVI) are investigated. Investigations started with column experiments in 40 cm columns filled with various porous media to investigate on physicochemical influences on transport characteristics. The experimental setup was enlarged to a transport experiment in a 1.2-m-sized two-dimensional aquifer tank experiment, which was filled with granular porous media. Further, a field experiment was performed in a natural aquifer system with a targeted transport distance of 5.3 m. Parallel to these investigations, alternative methods for transport observations were investigated by using noninvasive tomographic methods. Experiments using synchrotron radiation and magnetic resonance (MRI) were performed to investigate in situ transport characteristics in a non-destructive way. Results from column experiments show potentially high mobility under environmental relevant conditions. Addition of mono-and bivalent salts, e.g. more than 0.5 mM/L CaCl2, might decrease mobility. Changes in pH to values below 6 can inhibit mobility at all. Measurements of colloid size show changes in the mean particle size by a factor of ten. Measurements of zeta potential revealed an increase of -62 mV to -82 mV. Results from the 2D-aquifer test system suggest strong particle deposition in the first centimetres and only weak straining in the further travel path and no gravitational influence on particle transport. Straining at the beginning of the travel path in the porous medium was observed with tomographic investigations of transport. MRI experiments revealed similar results to the previous experiments, and observations using synchrotron radiation suggest straining of colloids at pore throats. The potential for high transport distances, which was suggested from laboratory experiments, was confirmed in the field experiment, where the transport distance of 5.3 m was reached by at least 10\% of injected nZVI. Altogether, transport distances of the investigated carbon-colloid supported nZVI are higher than published results of traditional nZVI.}, language = {en} } @book{Chirico2015, author = {Chirico, Rosaria}, title = {Workshop: Schreiben will gelernt sein!}, issn = {2364-3927}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-74694}, publisher = {Universit{\"a}t Potsdam}, pages = {11, VII}, year = {2015}, abstract = {Dieser Workshop wurde im Anschluss an den Workshop „Arbeiten bewerten" im Rahmen des sqb-Weiterbildungsangebots als eint{\"a}gige Veranstaltung angeboten, um die Einf{\"u}hrung in die prozessorientierte Schreibdidaktik zu vertiefen.

We propose a memory-based computational model that derives offline and online complexity profiles in terms of a top-down parser for minimalist grammars (Stabler, 2011). The complexity metric reflects the amount of time an item is stored in memory. The presented architecture links grammatical representations stored in memory directly to the cognitive behavior by deriving predictions about sentence processing difficulty. Results from five different sentence comprehension experiments were used to evaluate the model's assumptions about memory limitations. The predictions of the complexity metric were compared to the locality (integration and storage) cost metric of Dependency Locality Theory (Gibson, 2000). Both metrics make comparable offline and online predictions for four of the five phenomena. The key difference between the two metrics is that the proposed complexity metric accounts for the structural complexity of intervening material. In contrast, DLT's integration cost metric considers the number of discourse referents, not the syntactic structural complexity. We conclude that the syntactic analysis plays a significant role in memory requirements of parsing. An incremental top-down parser based on a grammar formalism easily computes offline and online complexity profiles, which can be used to derive predictions about sentence processing difficulty.}, language = {en} } @misc{Klinnert2015, type = {Master Thesis}, author = {Klinnert, Anne}, title = {Die Politik Deutschlands gegen{\"u}ber Zentralasien}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-286-5}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-70548}, school = {Universit{\"a}t Potsdam}, pages = {102}, year = {2015}, abstract = {Seit 1990 ist die vereinte, wieder souver{\"a}ne Bundesrepublik Deutschland auf der Suche nach ihrer Rolle in der Welt.

In SOV languages, however, the opposite effect has been found: antilocality (see discussion in Levy et al., 2013). Antilocality effects can be explained by the expectation-based approach as proposed by Levy (2008) or by the activation-based model of sentence processing as proposed by Lewis and Vasishth (2005). We report an eye-tracking and a self-paced reading study with sentences in Spanish together with measures of individual differences to examine the distinction between expectation- and memory-based accounts, and within memory-based accounts the further distinction between DLT and the activation-based model. The experiments show that (i) antilocality effects as predicted by the expectation account appear only for high-capacity readers; (ii) increasing dependency length by interposing material that modifies the head of the dependency (the verb) produces stronger facilitation than increasing dependency length with material that does not modify the head; this is in agreement with the activation-based model but not with the expectation account; and (iii) a possible outcome of memory load on low-capacity readers is the increase in regressive saccades (locality effects as predicted by memory-based accounts) or, surprisingly, a speedup in the self-paced reading task; the latter consistent with good-enough parsing (Ferreira et al., 2002). In sum, the study suggests that individual differences in working memory capacity play a role in dependency resolution, and that some of the aspects of dependency resolution can be best explained with the activation-based model together with a prediction component.}, language = {en} } @book{HerbstMaschlerNiephausetal.2015, author = {Herbst, Eva-Maria and Maschler, Fabian and Niephaus, Fabio and Reimann, Max and Steier, Julia and Felgentreff, Tim and Lincke, Jens and Taeumel, Marcel and Hirschfeld, Robert and Witt, Carsten}, title = {ecoControl}, number = {93}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-318-3}, issn = {1613-5652}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-72147}, publisher = {Universit{\"a}t Potsdam}, pages = {viii, 142}, year = {2015}, abstract = {Eine dezentrale Energieversorgung ist ein erster Schritt in Richtung Energiewende.

A precursor in this field was the study by Buccino et al. (2005) combining transcranial magnetic stimulation (TMS) and behavioral measures (reaction times, RTs) to study the effect of listening to hand- and foot-related sentences. In the TMS experiment, the authors showed a decrease of motor evoked potentials (MEPs) recorded from hand muscles when processing hand-related verbs as compared to foot-related verbs. Similarly, MEPs recorded from leg muscles decreased when participants processed foot-related as compared to hand-related verbs. In the behavioral experiment, using the same stimuli and a semantic decision task the authors found slower RTs when the participants used the body effector (hand or foot) involved in the actual execution of the action expressed by the presented verb to give their motor responses. These findings were interpreted as an interference effect due to a simultaneous involvement of the motor system in both a language and a motor task. Our replication aimed to enlarge the sample size and replicate the findings with higher statistical power. The TMS experiment showed a significant modulation of hand MEPs, but in the sense of a motor facilitation when processing hand-related verbs.

The insula is particularly involved in neural processes underlying iA. However, iA-related neural activity in the insula during the acute state of major depressive disorder (MDD) and in remission from depression has not been explored. Methods: A well-established fMRI paradigm for studying (iA; heartbeat counting) and exteroceptive awareness (eA; tone counting) was used. Study participants formed three independent groups: patients suffering from MDD, patients in remission from MDD or healthy controls. Task-induced neural activity in three functional subdivisions of the insula was compared between these groups. Results: Depressed participants showed neural hypo-responses during iA in anterior insula regions, as compared to both healthy and remitted participants. The right dorsal anterior insula showed the strongest response to iA across all participant groups. In depressed participants there was no differentiation between different stimuli types in this region (i.e., between iA, eA and noTask). Healthy and remitted participants in contrast showed clear activity differences. Conclusions: This is the first study comparing iA and eA-related activity in the insula in depressed participants to that in healthy and remitted individuals. The preliminary results suggest that these groups differ in there being hypo-responses across insula regions in the depressed participants, whilst non-psychiatric participants and patients in remission from MDD show the same neural activity during iA in insula subregions implying a possible state marker for MDD.

Methods To this end, we had prepubescent children (mean age: 8.7 ± 0.5 years, age range: 7-9 years) walk in single task (ST) and while concurrently conducting an arithmetic subtraction task (DT).

Furthermore, stepwise regressions indicate that leg lean tissue mass is closely associated with step time and the variability thereof during DT (R2 = 0.44, p = 0.009). These associations between gait measures and leg lean tissue mass could not be observed for ST (R2 = 0.17, p = 0.19).

The investigations done within this dissertation are one small step to shed some more light on this mystery. Locating the sources of cosmic rays is not trivial due to the interstellar magnetic field. However, the Hillas criterion allows us to arrive at the conclusion that supernova remnants are our main suspect for the origin of galactic cosmic rays. The mechanism by which they are accelerating particles is found within the field of shock physics as diffusive shock acceleration. To allow particles to enter this process also known as Fermi acceleration pre-acceleration processes like shock surfing acceleration and shock drift acceleration are necessary. Investigating the processes happening in the plasma shocks of supernova remnants is possible by utilising a simplified model which can be simulated on a computer using Particle-in-Cell simulations. We developed a new and clean setup to simulate the formation of a double shock, i.e., consisting of a forward and a reverse shock and a contact discontinuity, by the collision of two counter-streaming plasmas, in which a magnetic field can be woven into. In a previous work, we investigated the processes at unmagnetised and at magnetised parallel shocks, whereas in the current work, we move our investigation on to magnetised perpendicular shocks. Due to a much stronger confinement of the particles to the collision region the perpendicular shock develops much faster than the parallel shock. On the other hand, this leads to much weaker turbulence. We are able to find indications for shock surfing acceleration and shock drift acceleration happening at the two shocks leading to populations of pre-accelerated particles that are suitable as a seed population to be injected into further diffusive shock acceleration to be accelerated to even higher energies. We observe the development of filamentary structures in the shock ramp of the forward shock, but not at the reverse shock. This leads to the conclusion that the development of such structures in the shock ramp of quasi-perpendicular collisionless shocks might not necessarily be determined by the existence of a critical sonic Mach number but by a critical shock speed. The results of the investigations done within this dissertation might be useful for further studies of oblique shocks and for studies using hybrid or magnetohydrodynamic simulations. Together with more sophisticated observational methods, these studies will help to bring us closer to an answer as to how particles can be accelerated in supernova remnants and eventually become cosmic rays that can be detected on Earth.}, language = {en} } @phdthesis{Schirmack2015, author = {Schirmack, Janosch}, title = {Activity of methanogenic archaea under simulated Mars analog conditions}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-73010}, school = {Universit{\"a}t Potsdam}, pages = {VI, 108}, year = {2015}, abstract = {Assumed comparable environmental conditions of early Mars and early Earth in 3.7 Ga ago - at a time when first fossil records of life on Earth could be found - suggest the possibility of life emerging on both planets in parallel. As conditions changed, the hypothetical life on Mars either became extinct or was able to adapt and might still exist in biological niches. The controversial discussed detection of methane on Mars led to the assumption, that it must have a recent origin - either abiotic through active volcanism or chemical processes, or through biogenic production. Spatial and seasonal variations in the detected methane concentrations and correlations between the presence of water vapor and geological features such as subsurface hydrogen, which are occurring together with locally increased detected concentrations of methane, gave fuel to the hypothesis of a possible biological source of the methane on Mars. Therefore the phylogenetically old methanogenic archaea, which have evolved under early Earth conditions, are often used as model-organisms in astrobiological studies to investigate the potential of life to exist in possible extraterrestrial habitats on our neighboring planet. In this thesis methanogenic archaea originating from two extreme environments on Earth were investigated to test their ability to be active under simulated Mars analog conditions. These extreme environments - the Siberian permafrost-affected soil and the chemoautotrophically based terrestrial ecosystem of Movile cave, Romania - are regarded as analogs for possible Martian (subsurface) habitats. Two novel species of methanogenic archaea isolated from these environments were described within the frame of this thesis. It could be shown that concentrations up to 1 wt\% of Mars regolith analogs added to the growth media had a positive influence on the methane production rates of the tested methanogenic archaea, whereas higher concentrations resulted in decreasing rates. Nevertheless it was possible for the organisms to metabolize when incubated on water-saturated soil matrixes made of Mars regolith analogs without any additional nutrients. Long-term desiccation resistance of more than 400 days was proven with reincubation and indirect counting of viable cells through a combined treatment with propidium monoazide (to inactivate DNA of destroyed cells) and quantitative PCR. Phyllosilicate rich regolith analogs seem to be the best soil mixtures for the tested methanogenic archaea to be active under Mars analog conditions. Furthermore, in a simulation chamber experiment the activity of the permafrost methanogen strain Methanosarcina soligelidi SMA-21 under Mars subsurface analog conditions could be proven. Through real-time wavelength modulation spectroscopy measurements the increase in the methane concentration at temperatures down to -5 °C could be detected. The results presented in this thesis contribute to the understanding of the activity potential of methanogenic archaea under Mars analog conditions and therefore provide insights to the possible habitability of present-day Mars (near) subsurface environments. Thus, it contributes also to the data interpretation of future life detection missions on that planet.

Subjects were randomly assigned to resistance training (n = 19), balance training (n = 14), or a control group (n = 20). Bilateral heavy-resistance training for the lower extremities was performed for 13 weeks (3 × / week) at 80\% of the one repetition maximum. Balance training was conducted using predominately unilateral exercises on wobble boards, soft mats, and uneven surfaces for the same duration. Pre- and post-tests included uni- and bilateral measurements of maximal isometric leg extension force. At baseline, young subjects outperformed older adults in uni- and bilateral MIF (all p < .001; d = 2.61-3.37) and in measures of BLD (p < .001; d = 2.04). We also found significant increases in uni- and bilateral MIF after resistance training (all p < .001, d = 1.8-5.7) and balance training (all p < .05, d = 1.3-3.2). In addition, BLD decreased following resistance (p < .001, d = 3.4) and balance training (p < .001, d = 2.6). It can be concluded that both training regimens resulted in increased MIF and decreased BLD of the leg extensors (HRT-group more than BAL-group), almost reaching the levels of young adults.}, language = {en} } @phdthesis{Friedmann2015, author = {Friedmann, Ronald}, title = {Arthur Ewert (1890-1959)}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-73024}, school = {Universit{\"a}t Potsdam}, pages = {485}, year = {2015}, abstract = {Arthur Ewert (1890-1959) war in den zwanziger und fr{\"u}hen dreißiger Jahren ein wichtiger Funktion{\"a}r der Kommunistischen Partei Deutschlands und der Kommunistischen Internationale. Er wurde in der Familie eines armen Bauern in Ostpreußen geboren. Nach dem Abschluß der Schule ging er nach Berlin, um hier eine Lehre als Sattler zu absolvieren. {\"U}ber die Berliner Arbeiterjugendbewegung fand er Kontakt zur Sozialdemokratischen Partei Deutschlands, deren Mitglied er 1908 wurde. Im Mai 1914 emigrierte er gemeinsam mit seiner langj{\"a}hrigen Lebensgef{\"a}hrtin und sp{\"a}teren Ehefrau Elise Saborowski (1886-1939) nach Nordamerika, wo er sich sofort der sozialistischen Bewegung anschloß. Anfang 1919 geh{\"o}rte er zu den Mitbegr{\"u}ndern der ersten Kommunistischen Partei Kanadas. Im Sommer 1919 kehrte er nach Deutschland zur{\"u}ck und wurde Mitglied der wenige Monate zuvor gegr{\"u}ndeten KPD. Auf dem Leipziger Parteitag der KPD im Februar 1923 wurde er in die zwanzigk{\"o}pfige Zentrale seiner Partei gew{\"a}hlt und stieg damit in den engeren F{\"u}hrungszirkel auf. Nach der gescheiterten »Deutschen Oktoberrevolution« im Herbst 1923 k{\"a}mpfte er gemeinsam mit Ernst Meyer, Hugo Eberlein, Wilhelm Pieck und anderen um das {\"U}berleben der KPD, doch gelang es seiner Gruppe nicht, den Sieg der Linken und Ultralinken im parteiinternen Machtkampf zu verhindern. Ewert wurde politisch »kaltgestellt« und schied f{\"u}r mehr als ein Jahr aus der Parteif{\"u}hrung aus. In dieser Zeit erf{\"u}llte er verschiedene Aufgaben f{\"u}r die Kommunistische Internationale. Bereits im Juni 1923 war er Berichterstatter zur Lage in der Norwegischen Arbeiterpartei gewesen, ab Ende 1924 war er Abgesandter bei der KP Großbritanniens. Im Sommer und Fr{\"u}hherbst 1927 hielt er sich mehrere Monate in den USA auf. Im Sommer 1925 wurde er auf Veranlassung der Kommunistischen Internationale in die F{\"u}hrung der KPD zur{\"u}ckgeholt. Er trug wesentlich dazu bei, die Parteif{\"u}hrung unter Ernst Th{\"a}lmann zu stabilisieren und sie - zumindest zeitweise - auf einen realpolitischen Kurs zu orientieren. Mit dem erneuten »Links«-Schwenk der KPD ab Anfang 1928 wurde er als »Vers{\"o}hnler« stigmatisiert und zunehmend zur Zielscheibe innerparteilicher Attacken. Der Versuch eines »Befreiungsschlages« unter Ausnutzung der sogenannten Wittorf-Aff{\"a}re im Herbst 1928 scheiterte, bis zum Sommer 1929 wurde Arthur Ewert auf Dr{\"a}ngen Stalins und mit ausdr{\"u}cklicher Zustimmung Th{\"a}lmanns aus allen Funktionen in der KPD entfernt. Nach der Aufl{\"o}sung des Reichstags und dem damit verbundenen Verlust seines Reichstagsmandats im Juli 1930 schied Ewert endg{\"u}ltig aus der deutschen Parteiarbeit aus. Ende 1930 wurde er zum Leiter des S{\"u}damerikanischen B{\"u}ros der Kommunistischen Internationale in Montevideo, der Hauptstadt Uruguays, ernannt. Er trug damit Verantwortung f{\"u}r die unmittelbare Anleitung der Kommunistischen Parteien im sogenannten S{\"u}dkegel S{\"u}damerikas. In diese Zeit fielen seine ersten Kontakte zu Luiz Carlos Prestes, dem legend{\"a}ren »Ritter der Hoffnung«, mit dem er ab Anfang 1935 in Brasilien zusammenarbeitete. Von 1932 bis 1934 leitete Arthur Ewert das B{\"u}ro der Kommunistischen Internationale in Shanghai und spielte dabei eine entscheidende Rolle zugunsten Mao Tse-tungs, dessen politisches {\"U}berleben er in einem innerparteilichen Machtkampf der KP Chinas sicherte. Als Vertreter der Kommunistischen Internationale war Arthur Ewert im Verlaufe des Jahres 1935 an den Versuchen beteiligt, in Brasilien - gest{\"u}tzt auf ein breites B{\"u}ndnis, die »Nationale Befreiungsallianz« - einen politischen Machtwechsel herbeizuf{\"u}hren. Nach dem Scheitern des von Prestes gef{\"u}hrten Aufstandsversuches wurde er Ende 1935 verhaftet. Arthur Ewert verlor in Folge der barbarischen Folterungen in brasilianischer Haft den Verstand. Er kam im Mai 1945 im Ergebnis einer Amnestie frei. 1947 gelang es seiner Schwester, ihn in die sowjetische Besatzungszone zur{\"u}ckzuholen. Die {\"A}rzte dort konnten nur noch feststellen, daß eine Heilung unm{\"o}glich war. Arthur Ewert verbrachte den Rest seines Lebens in einem Pflegeheim in Eberswalde, wo er 1959 starb.}, language = {de} } @book{BauerBirgMaedingetal.2015, author = {Bauer, Hartmut and Birg, Herwig and M{\"a}ding, Heinrich and Appel, Clemens and K{\"u}hnert, Uwe and Falken, Christiane and Berg, Frank and Strauch, Friedrich and Reichard, Christoph and Petry, Klaus}, title = {Demografischer Wandel}, editor = {Bauer, Hartmut and B{\"u}chner, Christiane and Gr{\"u}ndel, Olaf}, edition = {3., durchges., Aufl.}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-323-7}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-72998}, publisher = {Universit{\"a}t Potsdam}, pages = {113}, year = {2015}, abstract = {Aus dem Editorial: „Negativzuwanderung" w{\"a}hlten die {\"O}sterreicher zu ihrem Unwort des Jahres 2005. Dieser Begriff verdeutlicht einen Aspekt des gesamtgesellschaftlichen Problems des demografischen Wandels, der nicht nur in {\"O}sterreich seit einiger Zeit f{\"u}r jeden zu sp{\"u}ren ist. Verstanden wird darunter die quantitative und qualitative Ver{\"a}nderung der Bev{\"o}lkerungsstruktur, die sich f{\"u}r Deutschland und die meisten westeurop{\"a}ischen L{\"a}nder mit drei Schlagworten beschreiben l{\"a}sst: weniger Kinder, mehr Alte, also insgesamt weniger Menschen. Allein f{\"u}r Deutschland wird bis 2050 ein Bev{\"o}lkerungsr{\"u}ckgang um 20\% erwartet. Davon betroffen sind alle Politikfelder, unter anderem die Bildungs- und Sozialpolitik sowie die Arbeitsmarkt- und Infrastrukturpolitik. Eine Herausforderung, die f{\"u}r Politik und Verwaltung gleichermaßen einmalig in der j{\"u}ngeren Geschichte ist. Als „unterste" Ebene sind die Kommunen und ihre Einrichtungen besonders stark betroffen, denn sie halten die Mehrzahl der infrastrukturellen und sonstigen {\"o}ffentlichen Einrichtungen f{\"u}r die Menschen vor, sie sind {\"u}ber einwohnerbezogene Finanzzuweisungssysteme abh{\"a}ngig von „ihren Menschen" und haben gleichzeitig wenig Einfluss auf die wirtschaftlich bedingten Zu- oder Wegz{\"u}ge der Einwohner. Sind diese Entwicklungen seit l{\"a}ngerer Zeit bekannt und werden intensiv diskutiert, so sind in letzter Zeit eine Reihe von Strategien und Handlungskonzepten entwickelt worden, um mit diesem Problem umgehen zu k{\"o}nnen. Das Kommunalwissenschaftliche Institut der Universit{\"a}t Potsdam (KWI) veranstaltete am 3. April 2006 eine Fachtagung „Demografie im Wandel. Herausforderungen f{\"u}r die Kommunen". Zum 12. Mal trafen sich seit der Gr{\"u}ndung des Institutes ca. 250 Vertreter der Wissenschaft, der Politik, der Verb{\"a}nde, insbesondere aber der Kommunen, um {\"u}ber aktuelle Demografieprobleme zu diskutieren. Dabei standen sowohl die wissenschaftliche Analyse als auch politische Handlungsstrategien im Fokus der Diskussion.

Our main tool is a new iterated version of the celebrated Mecke's formula from the point process theory, which allows us to study, as transformation on the path space, the addition of random loops. Thanks to the lattice structure of the set of loops, we even obtain a sharp characterization. At the end, we discuss several examples to illustrate the richness of reciprocal classes. We observe how their structure depends on the algebraic properties of the underlying group.}, language = {en} }
