N2 - Universities and their central units are increasingly concerned with research data management (RDM) in order to adequately support their researchers. Not least because of new publishing and funding policies, researchers seek advice and guidance on how to handle their research data. To enable universities to quickly and sustainably establish institutional RDM solutions, five universities from Berlin and Brandenburg have developed guidelines and tools in the joint project FDMentor funded by the German Federal Ministry of Education and Research (BMBF). The results achieved over a period of two years (2017–2019) in the areas of strategy development, research data policy, legal aspects and competence enhancement are applied beyond the project partners.

Here, we present isothermal hydrodynamic simulations of moonlet-induced propellers in Saturn's A ring that denote a further development of the original model. We find excellent agreement between these new hydrodynamic and corresponding N-body simulations. Furthermore, the hydrodynamic simulations confirm the predicted scaling laws and the analytical solution for the density in the propeller gaps. Finally, this mean field approach allows us to simulate the pattern of the giant propeller Blériot, which is too large to be modeled by direct N-body simulations. Our results are compared to two stellar occultation observations by the Cassini Ultraviolet Imaging Spectrometer (UVIS), which intersect the propeller Blériot. Best fits to the UVIS optical depth profiles are achieved for a Hill radius of 590 m, which implies a moonlet diameter of about 860 m. Furthermore, the model favors a kinematic shear viscosity of the surrounding ring material of ν0 = 340 cm2 s−1, a dispersion velocity in the range of 0.3 cm s−1 < c0 < 1.5 cm s−1, and a fairly high bulk viscosity 7 < ξ0/ν0 < 17. These large transport values might be overestimated by our isothermal ring model and should be reviewed by an extended model including thermal fluctuations.

Accretionary complexes exposed inland may comprise tectonic blocks with contrasting pressure-temperature (P-T) histories, making it possible to investigate the dynamics and thermal evolution of former subduction interfaces. With this aim, we present new Lu-Hf geochronological results for mafic rocks of the Halilbagi Complex (Anatolia) that evolved along different thermal gradients. Samples include a lawsonite-epidote blueschist, a lawsonite-epidote eclogite, and an epidote eclogite (all with counter-clockwise P-T paths), a prograde lawsonite blueschist with a "hairpin"-type P-T path, and a garnet amphibolite from the overlying sub-ophiolitic metamorphic sole. Equilibrium phase diagrams suggest that the garnet amphibolite formed at similar to 0.6-0.7 GPa and 800-850 degrees C, whereas the prograde lawsonite blueschist records burial from 2.1 GPa and 420 degrees C to 2.6 GPa and 520 degrees C. Well-defined Lu-Hf isochrons were obtained for the epidote eclogite (92.38 +/- 0.22 Ma) and the lawsonite-epidote blueschist (90.19 +/- 0.54 Ma), suggesting rapid garnet growth. The lawsonite-epidote eclogite (87.30 +/- 0.39 Ma) and the prograde lawsonite blueschist (ca. 86 Ma) are younger, whereas the garnet amphibolite (104.5 +/- 3.5 Ma) is older. Our data reveal a consistent trend of progressively decreasing geothermal gradient from granulite-facies conditions at similar to 104 Ma to the epidote-eclogite facies around 92 Ma, and the lawsonite blueschist-facies between 90 Ma and 86 Ma. Three Lu-Hf garnet dates (between 92 Ma and 87 Ma) weighted toward the growth of post-peak rims (as indicated by Lu distribution in garnet) suggest that the HP/LT rocks were exhumed continuously and not episodically. We infer that HP/LT metamorphic rocks within the Halilbagi Complex were subjected to continuous return flow, with "warm" rocks being exhumed during the tectonic burial of "cold" ones. Our results, combined with regional geological constraints, allow us to speculate that subduction started at a transform fault near a mid-oceanic spreading centre. Following its formation, this ancient subduction interface evolved thermally over more than 15 Myr, most likely as a result of heat dissipation rather than crustal underplating.

But the period between 1938 and 1945 remained a point of contention. While some Austrian officers had been sidelined, the majority had served in the Wehrmacht and thus shared experiences and soldierly values. As Cold War realities necessitated a professional experienced army, a group around Erwin Fussenegger (1908–1986) dominated the new Bundesheer and contemplations about reforming the military culture and value system were postponed; while at the same time, the Bundesheer managed to prevent becoming a mere continuation of the Wehrmacht.

In the case of cyanobacteria, phages can reduce primary production and infected hosts release intracellular nutrients influencing planktonic food web structure, community dynamics, and biogeochemical cycles. Cyanophages may be of great importance in aquatic food webs during large cyanobacterial blooms unless the host population becomes resistant to phage infection. The consequences on plankton community dynamics of the evolution of phage resistance in bloom forming cyanobacterial populations are still poorly studied. Here, we examined the effect of different frequencies of a phage-resistant genotype within a filamentous nitrogen-fixing Nodularia spumigena population on an experimental plankton community. Three Nodularia populations with different initial frequencies (0%, 5%, and 50%) of phage-resistant genotypes were inoculated in separate treatments with the phage 2AV2, the green alga Chlorella vulgaris, and the rotifer Brachionus plicatilis, which formed the experimental plankton community subjected to either nitrogen-limited or nitrogen-rich conditions. We found that the frequency of the phage-resistant Nodularia genotype determined experimental community dynamics. Cyanobacterial populations with a high frequency (50%) of the phage-resistant genotype dominated the cultures despite the presence of phages, retaining most of the intracellular nitrogen in the plankton community. In contrast, populations with low frequencies (0% and 5%) of the phage-resistant genotype were lysed and reduced to extinction by the phage, transferring the intracellular nitrogen held by Nodularia to Chlorella and rotifers, and allowing Chlorella to dominate the communities and rotifers to survive. This study shows that even though phages represent minuscule biomass, they can have key effects on community composition and eco-evolutionary feedbacks in plankton communities.

It has been suggested that anoxic conditions in shallow marine environments, linked to the end-Permian mass extinction, limited mat-inhibiting metazoans allowing for this microbialite expansion. The presence of a diverse suite of proxies indicating oxygenated shallow sea-water conditions (metazoan fossils, biomarkers and redox proxies) from microbialite successions have, however, challenged the inference of anoxic conditions. Here, the distribution and faunal composition of Griesbachian microbialites from China, Iran, Turkey, Armenia, Slovenia and Hungary are investigated to determine the factors that allowed microbialite-forming microbial mats to flourish following the end-Permian crisis. The results presented here show that Neotethyan microbial buildups record a unique faunal association due to the presence of keratose sponges, while the Palaeotethyan buildups have a higher proportion of molluscs and the foraminifera Earlandia. The distribution of the faunal components within the microbial fabrics suggests that, except for the keratose sponges and some microconchids, most of the metazoans were transported into the microbial framework via wave currents. The presence of both microbialites and metazoan associations were limited to oxygenated settings, suggesting that a factor other than anoxia resulted in a relaxation of ecological constraints following the mass extinction event. It is inferred that the end-Permian mass extinction event decreased the diversity and abundance of metazoans to the point of significantly reducing competition, allowing photosynthesis-based microbial mats to flourish in shallow water settings and resulting in the formation of widespread microbialites.

The core-shell nanoparticles are further self-assembled with negatively charged multi-walled carbon nanotubes (MWCNTs), which results in the formation of a free-standing cathode electrode. The porous SiO2 shell not only effectively improves the stability of the linear PTMA redox polymer with low molar mass in organic electrolytes but also leads to the uniform dispersion of PTMA active units in the MWCNTs conductive network. The PTMA@SiO2@MWCNT composite electrode exhibits a specific capacity as high as 73.8 mAh g at 1 C and only 0.11% capacity loss per cycle at a rate of 2 C.

Our 1350 km(2) study area is undisturbed, primarily forested terrain that has not experienced road building or timber harvesting. Our inventory of landslide polygons is based on optical airborne and spaceborne images acquired between 2007 and 2018, from which we extracted and mapped 446 individual landslides (an average of 33 landslides per 100 km(2)). The landslide rate in years without major earthquakes averages 19.4 per year, or 1.4/100 km(2)/year, and the annual average area covered by non-seismically triggered landslides is 35 ha/year. The number of landslides identified in imagery closely following the 2012 earthquake, and probably triggered by it, is 244 or an average of about 18 landslides per 100 km(2). These landslides cover a total area of 461 ha. In the following years-2013-2016 and 2016-2018-the number of landslides fell, respectively, to 26 and 13.5 landslides per year. In non-earthquake years, most landslides happen on south-facing slopes, facing the prevailing winds. In contrast, during or immediately after the earthquake, up to 32% of the landslides occurred on north and northwest-facing slopes. Although we could not find imagery from the day after the earthquake, overview reconnaissance flights 10 and 16 days later showed that most of the landslides were recent, suggesting they were co-seismic.

The development of the ecosystem depends on the activity of several reef builders, including red crustose coralline algae (CCA) such as Neogoniolithon brassica-florida. Despite its importance, little is known about Neogoniolithon sp. acclimation to rapid changes in light intensity and corresponding photosynthetic activity. To overcome the large spatial variability in the light field (due to location and the porous nature of the rocks) we grew Neogoniolithon sp. on glass slides and characterized its photosynthetic performance in response to various light intensities by following O-2 exchange and fluorescence parameters. This was also performed on rock-inhabiting thalli collected from the east Mediterranean basin. Generally, maximal photosynthetic rate was reached when Neogoniolithon sp. thalli grown under low illumination (such as in protected niches where the light intensity can be as low as 1% of surface illumination) were examined. When exposed to light intensities higher than those experienced during growth, Neogoniolithon sp. activates adaptive/protective mechanisms such as state transition and nonphotochemical fluorescence quenching and increases the dark respiration thereafter. We find that the Fv/Fm parameter (variable/maximal fluorescence) is not suitable to assess photosynthetic performance in Neogoniolithon sp. and propose using instead an alternative parameter recently developed. Our findings help to clarify why Neogoniolithon sp. is usually observed in shaded niches along the reef surfaces.

I propose that these deciduous and evergreen boreal forests represent alternative quasi-stable states, triggered by their different northern tree refugia that reflect the different environmental conditions experienced during the Last Glacial. Evidence This view is supported by palaeoecological and environmental evidence. Once established, Asian larch forests are likely to have stabilized through a complex vegetation-fire-permafrost soil-climate feedback system. Conclusion With respect to future forest developments, this implies that Asian larch forests are likely to be governed by long-term trajectories and are therefore largely resistant to natural climate variability on time-scales shorter than millennia. The effects of regional human impact and anthropogenic global warming might, however, cause certain stability thresholds to be crossed, meaning that irreversible transitions occur and resulting in marked consequences for ecosystem services on these human-relevant time-scales.

We studied the physiological, antioxidant and metabolic responses to three temperature conditions (4, 15, and 23 degrees C) of Colobanthus quitensis (CQ), one of the only two native vascular species in Antarctica. We also employed Dianthus chinensis (DC), to assess the effects of the treatments in a non-Antarctic species from the same family. Using fused LASSO modelling, we associated physiological and biochemical antioxidant responses with primary metabolism. This approach allowed us to highlight the metabolic pathways driving the response specific to CQ. Low temperature imposed dramatic reductions in photosynthesis (up to 88%) but not in respiration (sustaining rates of 3.0-4.2 mu mol CO2 m(-2) s(-1)) in CQ, and no change in the physiological stress parameters was found. Its notable antioxidant capacity and mitochondrial cytochrome respiratory activity (20 and two times higher than DC, respectively), which ensure ATP production even at low temperature, was significantly associated with sulphur-containing metabolites and polyamines. Our findings potentially open new biotechnological opportunities regarding the role of antioxidant compounds and respiratory mechanisms associated with sulphur metabolism in stress tolerance strategies to low temperature.

The underlying mechanisms of the association between letter knowledge and reading skills are, however, not fully understood. Acquiring letter knowledge depends on the ability to learn and retrieve sound–symbol pairings. In the current study, this process was explored by setting preschool children’s (N = 242, mean age = 5.57 years) performance in the acquisition and retrieval of a paired associate learning (PAL) task in relation to their letter knowledge as well as to their performance in tasks assessing precursors of reading skills (i.e., phonological awareness, rapid automatized naming, phonological short-term memory, backward recall, and response inhibition). Multiple regression analyses revealed that performance in the acquisition of the PAL task was significantly associated with phonological awareness and backward recall, whereas performance in the retrieval of the PAL task was significantly associated with rapid automatized naming, phonological awareness, and backward recall. Moreover, PAL proved to be mediating the relation between reading precursors and letter knowledge. Together, these findings indicate that the acquisition of letter knowledge may depend on a visual–verbal associative learning mechanism and that different factors contribute to the acquisition and retrieval of such visual–verbal associations.

T1 - Shift in the Raman symmetric stretching band of N-2, CO2, and CH4 as a function of temperature, pressure, and density JF - Journal of Raman spectroscopy : JRS N2 - The Raman spectra of pure N-2, CO2, and CH4 were analyzed over the range 10 to 500 bars and from -160 degrees C to 200 degrees C (N-2), 22 degrees C to 350 degrees C (CO2), and -100 degrees C to 450 degrees C (CH4). At constant temperature, Raman peak position, including the more intense CO2 peak (nu+), decreases (shifts to lower wave number) with increasing pressure for all three gases over the entire pressure and temperature (PT) range studied. At constant pressure, the peak position for CO2 and CH4 increases (shifts to higher wave number) with increasing temperature over the entire PT range studied. In contrast, N-2 first shows an increase in peak position with increasing temperature at constant pressure, followed by a decrease in peak position with increasing temperature. The inflection temperature at which the trend reverses for N-2 is located between 0 degrees C and 50 degrees C at pressures above similar to 50 bars and is pressure dependent. Below similar to 50 bars, the inflection temperature was observed as low as -120 degrees C. The shifts in Raman peak positions with PT are related to relative density changes, which reflect changes in intermolecular attraction and repulsion. A conceptual model relating the Raman spectral properties of N-2, CO2, and CH4 to relative density (volume) changes and attractive and repulsive forces is presented here. Additionally, reduced temperature-dependent densimeters and barometers are presented for each pure component over the respective PT ranges. The Raman spectral behavior of the pure gases as a function of temperature and pressure is assessed to provide a framework for understanding the behavior of each component in multicomponent N-2-CO2-CH4 gas systems in a future study.

This review will look at whether that is indeed the case. Social-science handbooks naturally are very broad. This also applies to the particular handbook under review. It comprises six content-thematic parts with 33 chapters by 73 authors from 21 countries, with the UK and USA dominant. The focal points, discussed in more detail below, are local elections and local governance, local governments in different jurisdictions, the challenges of local government services, citizen engagement in local affairs, and local authorities in multi-level finance systems that shape how municipal governments ‘get and spend’ public money. These are exactly the topics actually discussed in the international community of political scientists. As a preliminary, the editors work out the theoretical-methodological foundations of the topic. They define ‘the local’ as ‘geographically defined sub-national state administrative or political divisions’ (p. 3). As next steps, they analyse the difference between government and governance, and investigate whether local government is globally important and relevant. Fortunately, they conclude that this is indeed the case. Part I of the handbook illustrates ‘substantive variations’ in the local electoral systems and ‘notable divergences in the values and assumptions of local governance among democratic countries’ (p. 23). That topic is indeed central to local authorities’ legitimacy in democratic political systems. The focus of this part of the handbook is on current research and debates around local electoral systems, the challenges of local political leadership and the councillor’s role in modern local policy. Current trends at the local level are analysed from the actors’ perspectives or from an economic point of view by comparing institutionalised differences in city managers, mayors and council members across different jurisdictions. Sections that investigate traditional leadership and local government in Pacific Island countries are of particular interest to most Western readers, because in Europe and North America we know too little about such issues in that part of the world. Part II of the handbook presents current development processes and challenges in various local government systems. The chapters are territorially oriented around nation states or sub-national regions. This part of the handbook deal with local government in the Pacific Islands, Latin America, and New Zealand and in the Caribbean. However, the rationale behind country selection is not always clear; important countries like China, India and Nigeria, just to name a few, are absent. Unfortunately, there is no summary article highlighting similarities and differences, as well as the challenges in local government, relating to the countries studied in the book. The development of local services is the focus of Part III of the handbook, however, the definition of local services remains highly controversial and their scope varies widely between the countries. From the 1980s onwards, there was a long-term trend towards the marketisation and economisation of local politics, but since the turn of the millennium, there has been a counter-trend of the return of municipalities and third sector in the fields of local public services (Wollmann 2018). The book analyses the US and Georgia as case studies for development trends, finding that local government entrepreneurship remains an important factor in promoting economic development and strengthening capacities. I was pleased to see that Part IV, the next and most extensive part of the handbook, deals with citizen engagement, because the future of local self-government across the world depends not only on top down activities by local governing elites, but above all on the commitment of the inhabitants of cities and municipalities. Practices and challenges of citizen participation in local government are analysed in inspiring case studies of mid-sized cities in Russia and the United States. The contribution on urban governance of austerity in Europe is also of particular interest. The 2008 global financial crash and the subsequent severe budgetary pressure on municipalities in many countries was a key event in the history and development of local self-government, confronting municipalities with ‘the harsh realities of political economy’ (p. 293). Several articles analyse the causes of the declining confidence of the citizens in local authorities in some countries. In contrast, the open budget tool in Brazil is as a positive example of collaborative stakeholder engagement. Part V deals with multi-level governance. With the exception of Australia, it is all about Europe, especially the role of municipalities in the EU’s multilevel system. The authors conclude that ‘local authorities are essential for executing EU legislation, and this turn allows them to shape EU policies’ (p. 401). This part of the handbook includes the issue of local territorial reforms, which are central to local autonomy, combined with analyses of redesigning regional government and local-level Europeanisation. Subsequently, by comparing the local government systems of Southern Europe (France, Italy, Portugal and Spain), the authors underline convincingly the role of traditions, identity, legal frameworks and institutions in local government. Part VI of the book deals with the financial dimension of local self-government under the heading ‘Getting and spending’. This is indeed the ‘key source of dispute between local and central government’ (p. 467) and the crucial factor shaping true local autonomy. Meritoriously, this part also contains a chapter on the fight against corruption and unethical behaviour by public servants. Based on research linking corruption to transparency and accountability, two case studies describe how Tbilisi (Georgia) and Lviv (Ukraine) try to reduce corruption in government budgeting and procurement. Enhancing Value-For-Money audit in local government highlights another important side of local finance. An interesting comparison reveals significant differences in local government revenues in European Union member states between 2000 and 2014. Of course, even in a 530-page book, some important aspects remain underexposed. Above all, I would have liked more attention on some of the enormous future challenges facing democratic systems and with them local governments all over the world, such as digitisation (e.g. in smart cities), the integration of migrants or climate change. The international networking of municipalities should also be given greater prominence. To sum it up, The Routledge Handbook on International Local Government is indeed ‘ambitiously titled’ as the editors underline. Yet, despite my critical objections about its focus on current issues rather than future challenges, they largely fulfil this promise and their general approach has worked well. Across continents and political-administrative cultures, illustrated with many new research findings, they have created an outstanding publication focusing on the challenges and policy of local self-governmental authorities and other local stakeholders. There is a good chance that this handbook will belong in future to the social science standard works on local issues, and be included in academic political science teaching. May the publisher’s wish come true; that this book stimulates its readers to develop further research ideas. Finally, I come back to my initial question. ‘Old fashioned’ printed handbooks like these continue to make sense, even in modern digital times.

Jahrhundert wird sich so schnell verändern wie nie zuvor – und mit ihr das Gesundheitswesen. Bahnbrechende Entwicklungen in Forschung und Digitalisierung werden die Auswertung und Nutzung riesiger Datenmengen in kurzer Zeit ermöglichen. Das wird unsere Kenntnisse über Gesundheit und gesund sein, sowie über die Entstehung, Prävention und Heilung von Krankheiten vollkommen verändern. Gleichzeitig wird sich die Art und Weise, wie Medizin praktiziert wird, fundamental verändern. Das Selbstverständnis nahezu aller Akteure wird sich rasch weiterentwickeln müssen. Das Gesundheitssystem wird in allen Bereichen umgebaut und teilweise neu erfunden werden. Digitale Transformation, Personalisierung und Prävention sind die Treiber der neuen Medizin. Deutschland darf den Anschluss nicht verpassen. Im Vergleich mit anderen Ländern ist das deutsche Gesundheitswesen in vielen Punkten bedrohlich rückständig und fragmentiert. Um die Medizin und das Gesundheitswesen in Deutschland langfristig zukunftsfest zu machen, bedarf es vieler Anstrengungen – vor allem aber Offenheit gegenüber Veränderungen, sowie einen regulatorischen Rahmen, der ermöglicht, dass die medizinischen und digitalen Innovationen beim Patienten ankommen. DIE ZUKUNFT DER MEDIZIN beschreibt Entwicklungen und Technologien, die die Medizin und das Gesundheitswesen im 21. Jahrhundert prägen werden. Das Buch informiert über die zum Teil dramatischen, disruptiven Innovationen in der Forschung, die durch Big Data, Künstliche Intelligenz und Robotik möglich werden. Die Autoren sind führende Vordenker ihres Fachs und beschreiben aus langjähriger Erfahrung im In- und Ausland zukünftige Entwicklungen, die jetzt bereits greifbar sind.

A1 - Tapia, Joseline A1 - Pinto, Luisa T1 - Suspended sediments in chilean rivers reveal low postseismic erosion after the maule earthquake (Mw 8.8) during a severe drought JF - Journal of geophysical research : Earth surface N2 - We address the question of whether all large-magnitude earthquakes produce an erosion peak in the subaerial components of fluvial catchments. We evaluate the sediment flux response to the Maule earthquake in the Chilean Andes (Mw 8.8) using daily suspended sediment records from 31 river gauges. The catchments cover drainage areas of 350 to around 10,000 km(2), including a wide range of topographic slopes and vegetation cover of the Andean western flank. We compare the 3- to 8-year postseismic record of sediment flux to each of the following preseismic periods: (1) all preseismic data, (2) a 3-year period prior to the seismic event, and (3) the driest preseismic periods, as drought conditions prevailed in the postseismic period. Following the earthquake, no increases in suspended sediment flux were observed for moderate to high percentiles of the streamflow distribution (mean, median, and >= 75th percentile). However, more than half of the examined stations showed increased sediment flux during baseflow. By using a Random Forest approach, we evaluate the contributions of seismic intensities, peak ground accelerations, co-seismic landslides, hydroclimatic conditions, topography, lithology, and land cover to explain the observed changes in suspended sediment concentration and fluxes. We find that the best predictors are hillslope gradient, low-vegetation cover, and changes in streamflow discharge. This finding suggests a combined first-order control of topography, land cover, and hydrology on the catchment-wide erosion response. We infer a reduced sediment connectivity due to the postseismic drought, which increased the residence time of sediment detached and remobilized following the Maule earthquake.
