The study's objective was to determine the effects of leaf litter on bacterial metabolism in the littoral water and sediment, and subsequently, the consequences for carbon cycling and food web dynamics. Therefore, in late fall, we simultaneously measured water and sediment bacterial metabolism in the littoral zone of a temperate shallow lake after adding terrestrial particulate organic matter (t-POM), namely, maize leaves. To better evaluate bacterial production (BP) and community respiration (CR) in sediments, we incubated sediment cores with maize leaves of different quality (nonleached and leached) under controlled laboratory conditions. Additionally, to quantify the incorporated leaf carbon into microbial biomass, we determined carbon isotopic ratios of fatty acids from sediment and leaf-associated microbes from a laboratory experiment using C-13-enriched beech leaves. The concentrations of dissolved organic carbon (DOC) increased significantly in the lake after the addition of maize leaves, accompanied by a significant increase in water BP. In contrast, sediment BP declined after an initial peak, showing no positive response to t-POM addition. Sediment BP and CR were also not stimulated by t-POM in the laboratory experiment, either in short-term or in long-term incubations, except for a short increase in CR after 18 hours. However, this increase might have reflected the metabolism of leaf-associated microorganisms. We conclude that the leached t-DOM is actively incorporated into microbial biomass in the water column but that the settling leached t-POM (t-POML) does not enter the food web via sediment bacteria. Consequently, t-POML is either buried in the sediment or introduced into the aquatic food web via microorganisms (bacteria and fungi) directly associated with t-POML and via benthic macroinvertebrates by shredding of t-POML. The latter pathway represents a benthic shortcut which efficiently transfers t-POML to higher trophic levels.

In recent years, however, this sector has attracted more attention due to the occurrence of severe drought periods. Irrigation scheduling systems could support adaptation strategies but little is known about current providers, performance and users. In this study we aimed to depict the current situation of the existence and functioning of irrigation scheduling systems available in Germany. Six methods were identified and assessed based on direct interviews with end-users and a comparative analysis. The results showed a positive feedback from the users. However, the recommendations were rarely implemented, while only the seasonal irrigation requirement was considered to support actual water abstraction. These results were corroborated by the comparative analysis. Five of the six irrigation scheduling systems estimated the seasonal irrigation amount consistently, while wider differences were found by looking at the irrigation season and at the number of irrigations. Overall, it is found that irrigation support systems are valuable tools for supporting adaptation strategies to fast changes in agro-environmental conditions. However, specific assessments based on real measurements should be considered in order to improve the performance of the systems and provide more consistent support to end-users.

Furthermore, we shed light on the carriers and qualification profiles of the top bureaucrats in meso-level administrations. These high-rank territorial administrators/executives—state appointed heads of administrative districts (Regierungspräsidenten) on the one hand, elected heads of county administrations (Landräte) on the other hand—can be regarded as the German ‘equivalents’ of the prefects in countries with a Napoleonic administrative tradition. Finally, we analyse major reforms that have led to (at times, profound) transformations in territorial administrations, raising the question of to what extent alternative models of territorial bundling and coordination functions are sound and sustainable.

Dementia poses a major challenge to the healthcare system and neuropharmacological service provision. The aim of this study was to determine prescription rates for anti-dementia drugs as well as for neuroleptics, sedative-hypnotics and antidepressants in dementia using the complete nationwide outpatient claims data pertaining to the services of statutory health insurance. We controlled for gender, age, dementia diagnosis, physician specialty (general practitioner GP versus neuropsychiatry specialist physician NPSP), and rural and urban living area. In about one million prevalent dementia patients (N=1,014,710) in 2011, the prescription prevalence rate of anti-dementia drugs was 24.6%; it varied with gender, age, and diagnosis (highest in Alzheimer's disease; 42%), and was higher in patients treated by NPSPs (48% vs. 25% in GPs). At the same time, we found an alarmingly high rate of treatment with neuroleptics in dementia patients (35%), with an only slightly decreased risk in patients treated exclusively by NPSPs (OR=0.86). We found marginal differences between rural and urban areas. Our results show that the majority of anti-dementia drug prescriptions appear guideline-oriented, yet prescription rates are overall comparatively low. On the other hand, neuroleptic drugs, which are associated with excess morbidity and mortality in dementia, were prescribed very frequently, suggesting excess use given current guidelines. We therefore suggest that guideline implementation measures and increasing quality control procedures are needed with respect to the pharmacotherapy of this vulnerable population.

In a preliminary re-mark, I will reflect on some recent developments in Germany, where nativist protest campaigns against immigration took place in the streets when voters were turning towards the populist radical right party Alternative für Deutschland (AfD). In the first section, I will outline an older tradition of anti-immigration protest in nineteenth and early twentieth century Germany, which is closely connected to modern antisemitism. In sections two and three, I will retrace how, from the late 1960s onward, the far right in the Federal Republic of Germany (FRG) discovered concerns about immigra-tion in the German population, addressed them in protest campaigns and developed narratives to integrate such sentiments into a broader right-wing extremist ideology, itself deeply rooted in antisemitism. Studying nativism and the radical right from an actor-oriented perspective, I will focus on traditionalist movements, including the Nationaldemokratische Partei Deutschlands (NPD) and neo-Nazi groups.

N2 - This thesis work compares civic participation in French and German urban communities. Over the last 20 years, democracy in these communities has taken different forms, continually adapting to local conditions. Citizens, administration, and elected politicians gain interest in participation. However, this requires the three players to adapt to the new structures and develop independent strategies. Participatory and cooperative democracy become more common. This thesis evaluates different instruments of civic participation in France and Germany by distinguishing between Input, Output, and Outcome. In particular, I focus on participatory budgets, advisory boards and participatory neighborhood councils/'District Committee's. The results provide insights into the future development of democracy in German cities.

This article explores the origins of the change in attitude towards nuclear energy and argues that seven years before the Chernobyl disaster, the accident at the U.S. power plant Three Mile Island near Harrisburg, Pennsylvania, in 1979, had a profound impact which nowadays seems to be largely forgotten in Europe. The article identifies the structural causes underlying the transnational reception of the Three Mile Island accident and explores international reactions, particularly in the Federal Republic of Germany. The accident near Harrisburg led to a loss of public confidence and created unease about nuclear expansion in many industrialized nations. Reactions to the accident can be understood as an attempt to tame nuclear energy both technically, by increasing safety measures and abandoning plans for new nuclear power stations, and politically, with a more critical appraisal of nuclear energy and with semantics that encouraged a long-term withdrawal from nuclear power. Critics were now also accepted as experts. Nuclear policy in all countries became closely dependent on public opinion, indicating a high level of political responsiveness. Various factors, however, including the contemporaneous oil crisis put the brakes on this critical approach to nuclear power, while safety improvements and the limited expansion of nuclear power created new confidence in the early 1980s.

In this context rose also the rap music. It has a huge popularity for young people with migration background. However rappers do write a lot about their French or German identity. The goal of this work is to explain the paradox : how can people with migration background, expressing critics against the racism they regard as omnipresent, still feel fully French/German? We divided the work between following chapters: Context, methodology and theories (I); analysis of different identity forms within the text corpus (II); analysis of the way rappers see their society in three chronological steps (III-V); case studies of Kery James in France and Samy Deluxe in Germany (VI). N2 - In Frankreich sowie in Deutschland ist die Einwanderung in den letzten Jahrzehnten zu einer der wichtigsten gesellschaftlichen Themen geworden. Zur gleichen Zeit entstand auch die Rap-Musik, welche eine große Popularität bei Jugendlichen mit Migrationshintergrund genießt. Jedoch thematisieren Rapper mit Migrationshintergrund in Frankreich wie in Deutschland ihre Nationalidentität immer öfter. Ziel dieser Arbeit ist, folgendes Paradoxon zu erklären: wie können sich Menschen mit Migrationshintergrund völlig französisch/deutsch fühlen, obwohl sie eine starke Kritik am Rassismus äußern, den sie als gesellschaftlich prägend betrachten? Diese Arbeit wurde in folgende Kapitel unterteilt: Kontext, Methodik und Theorien (I); Analyse der verschiedenen Identitätsformen im Textkorpus (II); Analyse der Art und Weise, wie Rapper die Gesellschaft sehen, in drei chronologischen Etappen (III-V); Fallstudien von Kery James in Frankreich und Samy Deluxe in Deutschland (VI).

All Eastern German States (Länder) have set up inter-departmental committees (IDCs) that are expected to deliver joint strategies to tackle demographic change. IDCs provide an organizational setting for potential positive coordination, i.e. a joint approach to problem solving that pools and utilizes the expertise of many departments in a constructive manner from the very beginning. Whether they actually achieve positive coordination is contested within the academic debate. This motivates the first research question of this thesis: Do IDCs achieve positive coordination? Interdepartmental committees and their role in horizontal coordination within the core executive triggered interest among scholars already more than fifty years ago. However, we don’t know much about their actual importance for the inter-departmental preparation of cross-cutting policies. Until now, few studies can be found that analyzes inter-departmental committees in a comparative way trying to identify whether they achieve positive coordination and what factors shape the coordination process and output of IDCs. Each IDC has a chair organization that is responsible for managing the interactions within the IDCs. The chair organization is important, because it organizes and structures the overall process of coordination in the IDC. Consequently, the chair of an IDC serves as the main boundary-spanner and therefore has remarkable influence by arranging meetings and the work schedule or by distributing internal roles. Interestingly, in the German context we find two organizational approaches: while some states decided to put a line department (e.g. Department of Infrastructure) in charge of managing the IDC, others rely on the State Chancelleries, i.e. the center of government. This situation allows for comparative research design that can address the role of the State Chancellery in inter-departmental coordination of cross-cutting policies. This is relevant, because the role of the center is crucial when studying coordination within central government. The academic debate on the center of government in the German politico-administrative system is essentially divided into two camps. One camp claims that the center can improve horizontal coordination and steer cross-cutting policy-making more effectively, while the other camp points to limits to central coordination due to departmental autonomy. This debate motivates the second research question of this thesis: Does the State Chancellery as chair organization achieve positive coordination in IDCs? The center of government and its role in the German politic-administrative system has attracted academic attention already in the 1960s and 1970s. There is a research desiderate regarding the center’s role during the inter-departmental coordination process. There are only few studies that explicitly analyze centers of government and their role in coordination of cross-cutting policies, although some single case studies have been published. This gap in the academic debate will be addressed by the answer to the second research question. The dependent variable of this study is the chair organization of IDCs. The value of this variable is dichotomous: either an IDC is chaired by a Line department or by a State Chancellery. We are interested whether this variable has an effect on two dependent variables. First, we will analyze the coordination process, i.e. interaction among bureaucrats within the IDC. Second, the focus of this thesis will be on the coordination result, i.e. the demography strategies that are produced by the respective IDCs. In terms of the methodological approach, this thesis applies a comparative case study design based on a most-similar-systems logic. The German Federalism is quite suitable for such designs. Since the institutional framework largely is the same across all states, individual variables and their effect can be isolated and plausibly analyzed. To further control for potential intervening variables, we will limit our case selection to states located in East Germany, because the demographic situation is most problematic in the Eastern part of Germany, i.e. there is a equal problem pressure. Consequently, we will analyze five cases: Thuringia, Saxony-Anhalt (line department) and Brandenburg, Mecklenburg-Vorpommern and Saxony (State Chancellery). There is no grand coordination theory that is ready to be applied to our case studies. Therefore, we need to tailor our own approach. Our assumption is that the individual chair organization has an effect on the coordination process and output of IDCs, although all cases are embedded in the same institutional setting, i.e. the German politico-administrative system. Therefore, we need an analytical approach than incorporates institutionalist and agency-based arguments. Therefore, this thesis will utilize Actor-Centered Institutionalism (ACI). Broadly speaking, ACI conceptualizes actors’ behavior as influenced - but not fully determined - by institutions. Since ACI is rather abstract we need to adapt it for the purpose of this thesis. Line Departments and State Chancelleries will be modeled as distinct actors with different action orientations and capabilities to steer the coordination process. However, their action is embedded within the institutional context of governments, which we will conceptualize as being comprised of regulative (formal rules) and normative (social norms) elements. N2 - Die vorliegende Arbeit beschäftigt sich mit interministerieller Koordination der Demografiepolitik in ostdeutschen Ländern. Alle ostdeutschen Länder haben interministerielle Arbeitsgruppen (IMAGs) eingerichtet, die von der jeweiligen Landesregierung beauftragt wurden, ressortübergreifende Strategien zur Bewältigung der Folgen des demografischen Wandels zu erarbeiten. IMAGs bieten potentiell einen organisatorischen Rahmen für das Gelingen positiver Koordination, also der ressortübergreifenden Bearbeitung interdependenter Problemstellungen. Ob sie jedoch tatsächlich positive Koordination herbeiführen, ist innerhalb der akademischen Debatte umstritten, was die Motivation für die erste Forschungsfrage darstellt: Führen IMAGs zu positiver Koordination? IMAGs haben bereits vor fünfzig Jahren akademische Aufmerksamkeit erregt. Dennoch ist über ihren Beitrag zur Vorbereitung ressortübergreifender Programme kaum etwas bekannt. Bislang haben nur wenige Arbeiten IMAGs in vergleichender Perspektive behandelt. Somit fehlt es an Wissen zu Determinanten des Koordinationsprozesses und –ergebnisses interministerieller Arbeitsgruppen. Jeweils einer Organisation obliegt die Federführung für die jeweilige IMAG. Die federführende Einheit kann erheblichen Einfluss ausüben, da sie den Koordinationsprozess strukturiert und organisiert. Interessanterweise haben die ostdeutschen Bundesländer zwei unterschiedliche organisatorische Modelle gewählt: Entweder obliegt die Federführung der entsprechenden IMAG einem Fachministerien oder der Staatskanzlei des entsprechenden Landes. Diese Situation erlaubt ein vergleichendes Untersuchungsdesign, das die Rolle von Staatskanzleien im Prozess ressortübergreifender Politikformulierung im politisch-administrativen System Deutschlands zu untersuchen erlaubt. Die akademische Debatte im Hinblick darauf lässt sich etwas zugespitzt in zwei Lager teilen: Während das erste Lager argumentiert, die Regierungszentrale könne horizontale Koordination verbessern und zur effektiveren Steuerung ressortübergreifenden Politikformulierung beitragen, rekurriert das zweite Lager auf die Dominanz des verfassungsrechtlichen Ressortprinzip und geht von einer klaren Begrenzung der Steuerungskapazität von Regierungszentralen aus. Dies motiviert die zweite Forschungsfrage der vorliegenden Arbeit: Erreicht Federführung durch Staatskanzleien positive Koordination in IMAGs? Obwohl die Regierungszentrale schon frühzeitig Gegenstand verwaltungs- und politikwissenschaftlicher Forschung war, finden sich kaum Arbeiten, die explizit die Rolle von Staatskanzlei im Prozess der Formulierung ressortübergreifender Programme thematisieren. Die unabhängige Variable dieser Untersuchung ist die federführende Organisation einer IMAG (Staatskanzlei oder Fachministerium). Die abhängigen Variablen sind einerseits der Koordinationsprozess innerhalb von IMAGs als auch das entsprechende Koordinationsergebnis in Form ressortübergreifender Strategien zur Bewältigung des demografischen Wandels. Das Untersuchungsdesign entspricht einem most-similar-systems Ansatz. So finden sich in allen untersuchten Fällen Koalitionsregierungen, ein ähnlicher Problemdruck in Hinblick auf demografische Entwicklungen sowie ein nahezu identischer institutionelle Rahmen für Koordination. Der Einfluss der unabhängigen auf die abhängigen Variablen kann damit plausiblen isoliert werden. Die Studie untersucht IMAGs in den Ländern Thüringen, Sachsen-Anhalt (Federführung bei einem Fachministerium), Brandenburg, Mecklenburg-Vorpommern und Sachsen (Federführung bei der Staatskanzlei). Die Arbeit nutzt den akteurszentrierten Institutionalismus als analytischen Rahmen. Dieser erlaubt Koordinationsprozesse sowohl in Hinblick auf ihre institutionelle Einbettung zu untersuchen, die Rolle intentional handelnder Akteure mit unterschiedlichen Handlungsorientierungen und -möglichkeiten aus dem Blick zu verlieren.

To address this, we present a novel method for the comprehensive and near-real-time monitoring of drought socio-economic impacts based on media reports. We tested its application using the case of the exceptional 2018/19 German drought. By employing text mining techniques, 4839 impact statements were identified, relating to livestock, agriculture, forestry, fires, recreation, energy and transport sectors. An accuracy of 95.6% was obtained for their automatic classification. Furthermore, high levels of performance in terms of spatial and temporal precision were found when validating our results against independent data (e.g. soil moisture, average precipitation, population interest in droughts, crop yield and forest fire statistics). The findings highlight the applicability of media data for rapidly and accurately monitoring the propagation of drought consequences over time and space. We anticipate our method to be used as a starting point for an impact-based early warning system.

Dabei erweist sich die französische Verwaltungsgerichtsordnung aus rechtsvergleichender Sicht als progressiv, da das Verfahrensinstrument hier – im Gegensatz zur deutschen Rechtslage – bereits positiv-rechtlich normiert ist. Diese Fortschrittlichkeit hat sich bisher jedoch nicht merklich auf die Drittinterventionspraxis niedergeschlagen, besitzen Amicus Curiae-Stellungnahmen doch in beiden Ländern und über alle verwaltungsgerichtlichen Instanzen hinweg noch immer Seltenheitswert. Da mithin keine Generalisierungen zur dieser Rechtspraxis erlaubt sind, kann sich eine Analyse der möglichen funktionalen Rolle derartiger Amicus Curiae-Stellungnahmen nur auf theoretische Überlegungen stützen. Danach ist eine Informationsfunktion gegenüber dem Gericht in Bezug auf Tatsachen- und Rechtsfragen klar zu bejahen. Auch dürfte der Verfahrensmechanismus ein zusätzliches – wenngleich nicht demokratisches – Legitimationspotential für gerichtliche Entscheidungen besitzen: Indem dieser gesellschaftliche Teilhabe und damit gleichzeitig die Einbettung verwaltungsgerichtlicher Verfahren in den jeweiligen sozialen Kontext ermöglicht, kann er zur Steigerung der gesellschaftlichen Akzeptanz der zunehmend unter Rechtsfertigungsdruck geratenden Richtermacht beitragen. N2 - Ces dernières années, le concept de l’amicus curiae, qui puise ses racines dans le droit anglo-américain, a fait son entrée dans la juridiction administrative tant en Allemagne qu’en France, bien que sous des formes différentes. Du point de vue du droit comparé, le système judiciaire administratif français est relativement progressif à cet égard, car cet instrument procédural y est déjà codifié – contrairement à la situation juridique allemande. Toutefois, cette progressivité n'a pas eu jusqu'à présent d'effet notable sur la pratique procédurale, car l’application du concept d’amicus curiae demeure relativement rare dans l’ensemble des instances des juridictions administratives des deux pays. En conséquence, dans la mesure où une généralisation par rapport à cette pratique juridique n'est donc pas possible, la question de savoir quel est le rôle fonctionnel potentiel d’amici curiae ne peut être analysée que sur le plan théorique. Sur cette base, on peut affirmer clairement un rôle d'information vis-à-vis du tribunal par rapport aux questions de fait et de droit. En outre, ce mécanisme procédural semble avoir une capacité de légitimation supplémentaire du pouvoir judiciaire, bien qu’il ne s’agisse pas d’une légitimation démocratique : en permettant une participation sociale, et en reliant ainsi les procédures devant les juridictions administratives à leur contexte social respectif, l’amicus curiae contribue à augmenter l’adhésion sociale au pouvoir judiciaire, qui est de plus en plus contraint de s’auto-justifier vis-à-vis des justiciables. N2 - In recent years, the amicus curiae, which has its roots in Anglo-American law, has found its way into the administrative court systems in Germany and France, albeit in different forms. From a comparative law perspective, the French administrative court system proves to be progressive, since the procedural instrument of amicus curiae is already legally standardized here - in contrast to the German legal situation. However, this progressiveness has not yet had a noticeable impact on third-party intervention practice, given that amicus curiae briefs are still a rarity across all administrative court instances in both countries. Since no generalizations about this legal practice are hence permitted, an analysis of the possible functional role of such amicus curiae briefs can only be based on theoretical considerations. According to these considerations, an informational function vis-à-vis the court with respect to questions of fact and law can clearly be affirmed. The procedural mechanism of amicus curiae intervention is also likely to have an additional - albeit non-democratic - legitimizing potential for judicial decisions: By enabling social participation and thus at the same time embedding administrative court proceedings in the respective social context, it can contribute to enhanced social acceptance of the power of judges, which is under increasing pressure to justify itself.

Longitudinal data from general practices (n=1072) throughout Germany were analyzed. Individuals initially diagnosed with RA (2009-2013) were identified, and 7301 patients were included and matched (1:1) to 7301 controls. The primary outcome measure was the initial diagnosis of depression within 5 years after the index date in patients with and without RA. Cox proportional hazards models were used to adjust for confounders. The mean age was 72.2 years (SD: 7.6 years). A total of 34.9 % of patients were men. Depression diagnoses were present in 22.0 % of the RA group and 14.3 % of the control group after a 5-year follow-up period (p < 0.001). In the multivariate regression model, RA was a strong risk factor for the development of depression (HR: 1.55, p < 0.001). There was significant interaction of RA and diagnosed inflammatory polyarthropathies (IP) (RA*IP interaction: p < 0.001). Furthermore, dementia, cancer, osteoporosis, hypertension, and diabetes were associated with a higher risk of developing depression (p values < 0.001). The risk of depression is significantly higher in patients with late-onset RA than in patients without RA for subjects treated in primary care practices in Germany. RA patients should be screened routinely for depression in order to ensure improved treatment and management.

However, the basis of successful plant invasion is not conclusively understood, especially since these plant species can adapt to the new range within a short period of time despite impoverished genetic diversity of the starting populations. In this context, DNA methylation is considered promising to explain successful adaptation mechanisms in the new habitat. DNA methylation is a heritable variation in gene expression without changing the underlying genetic information. Thus, DNA methylation is considered a so-called epigenetic mechanism, but has been studied in mainly clonally reproducing plant species or genetic model plants. An understanding of this epigenetic mechanism in the context of non-native, predominantly sexually reproducing plant species might help to expand knowledge in biodiversity research on the interaction between plants and their habitats and, based on this, may enable more precise measures in conservation biology. For my studies, I combined chemical DNA demethylation of field-collected seed material from predominantly sexually reproducing species and rearing offsping under common climatic conditions to examine DNA methylation in an ecological-evolutionary context. The contrast of chemically treated (demethylated) plants, whose variation in DNA methylation was artificially reduced, and untreated control plants of the same species allowed me to study the impact of this mechanism on adaptive trait differentiation and local adaptation. With this experimental background, I conducted three studies examining the effect of DNA methylation in non-native species along a climatic gradient and also between climatically divergent regions. The first study focused on adaptive trait differentiation in two invasive perennial goldenrod species, Solidago canadensis sensu latu and S. gigantea AITON, along a climate gradient of more than 1000 km in length in Central Europe. I found population differences in flowering timing, plant height, and biomass in the temporally longer-established S. canadensis, but only in the number of regrowing shoots for S. gigantea. While S. canadensis did not show any population structure, I was able to identify three genetic groups along this climatic gradient in S. gigantea. Surprisingly, demethylated plants of both species showed no change in the majority of traits studied. In the subsequent second study, I focused on the longer-established goldenrod species S. canadensis and used molecular analyses to infer spatial epigenetic and genetic population differences in the same specimens from the previous study. I found weak genetic but no epigenetic spatial variation between populations. Additionally, I was able to identify one genetic marker and one epigenetic marker putatively susceptible to selection. However, the results of this study reconfirmed that the epigenetic mechanism of DNA methylation appears to be hardly involved in adaptive processes within the new range in S. canadensis. Finally, I conducted a third study in which I reciprocally transplanted short-lived plant species between two climatically divergent regions in Germany to investigate local adaptation at the plant family level. For this purpose, I used four plant families (Amaranthaceae, Asteraceae, Plantaginaceae, Solanaceae) and here I additionally compared between non-native and native plant species. Seeds were transplanted to regions with a distance of more than 600 kilometers and had either a temperate-oceanic or a temperate-continental climate. In this study, some species were found to be maladapted to their own local conditions, both in non-native and native plant species alike. In demethylated individuals of the plant species studied, DNA methylation had inconsistent but species-specific effects on survival and biomass production. The results of this study highlight that DNA methylation did not make a substantial contribution to local adaptation in the non-native as well as native species studied. In summary, my work showed that DNA methylation plays a negligible role in both adaptive trait variation along climatic gradients and local adaptation in non-native plant species that either exhibit a high degree of genetic variation or rely mainly on sexual reproduction with low clonal propagation. I was able to show that the adaptive success of these non-native plant species can hardly be explained by DNA methylation, but could be a possible consequence of multiple introductions, dispersal corridors and meta-population dynamics. Similarly, my results illustrate that the use of plant species that do not predominantly reproduce clonally and are not model plants is essential to characterize the effect size of epigenetic mechanisms in an ecological-evolutionary context. N2 - Die zunehmende Eintragung nicht-heimischer Pflanzenarten kann eine Gefahr für die lokale Artenvielfalt darstellen. Die Grundlagen einer erfolgreichen pflanzlichen Ausbreitung sind jedoch nicht abschließend geklärt, zumal sich diese Arten innerhalb kurzer Zeit an das neue Verbreitungsgebiet anpassen können trotz anfänglich reduzierter genetischer Vielfalt der Startpopulationen. In diesem Kontext gilt DNA-Methylierung als vielversprechend, um erfolgreiche Anpassungsmechanismen im neuen Lebensraum zu erklären. Bei der DNA-Methylierung handelt es sich um eine vererbbare Variation der Genaktivität, ohne dass die zugrundeliegende genetische Erbinformation verändert wird. Damit gehört DNA-Methylierung zu den sogenannten epigenetischen Mechanismen, wurde jedoch vorwiegend bei sich klonal vermehrenden Pflanzenarten oder genetischen Modellpflanzen untersucht. Ein Verständnis dieses epigenetischen Mechanismus im Zusammenhang mit nicht-einheimischen, sich vorwiegend sexuell reproduzierenden Pflanzenarten erweitert das Wissen in der Biodiversitätsforschung zur Interaktion zwischen Pflanzen und ihrem Lebensraum und kann, darauf aufbauend, präzisere Maßnahmen in der Naturschutzbiologie ermöglichen. Für meine Studien kombinierte ich die chemische DNA-Demethylierung von im Freiland gesammeltem Samenmaterial sich vorwiegend sexuell fortpflanzender Arten und die Aufzucht unter gemeinsamen klimatischen Bedingungen, um DNA-Methylierung im ökologisch-evolutionären Kontext zu untersuchen. Der Kontrast von chemisch behandelten (demethylierten) Pflanzen, deren Methylierungsvariation nun künstlich verringert war, und unbehandelten Kontrollpflanzen derselben Art ermöglichte mir die Auswirkung dieses Mechanismus auf adaptive Merkmalsvariationen und lokale Anpassung zu studieren. Vor diesem experimentellen Hintergrund führte ich drei Studien durch, um die Auswirkung von DNA-Methylierung bei nicht-einheimischen Pflanzenarten entlang eines klimatischen Gradienten und zwischen zwei klimatisch unterschiedlichen Regionen zu untersuchen. Die erste Studie konzentrierte sich auf adaptive Merkmalsveränderungen bei Nachkommen von zwei invasiven, mehrjährigen Goldrutenarten, Solidago canadensis sensu latu und S. gigantea AITON, entlang eines Klimagradienten von mehr als 1000 km Länge in Zentraleuropa. Ich fand graduelle Unterschiede im Blühzeitpunkt, in der Pflanzenhöhe und der Biomasse bei der zeitlich länger etablierten S. canadensis, bei S. gigantea jedoch nur in der Anzahl der nachwachsenden Triebe. Während S. canadensis keinerlei Populationsstruktur aufwies, konnte ich bei S. gigantea drei genetische Gruppen entlang dieses Klimagradienten identifizieren. Überraschenderweise zeigten demethylierte Pflanzen beider Arten keine Veränderung in der überwiegenden Anzahl der untersuchten Merkmale. In der darauffolgenden zweiten Studie konzentrierte ich mich auf die länger etablierte Goldrutenart S. canadensis und verwendete molekulare Analysen, um räumliche epigenetische und genetische Populationunterschiede aus den Exemplaren der vorhergehenden Studie abzuleiten. Ich fand schwache genetische aber keine epigenetische räumliche Variation zwischen den Populationen. Zusätzlich konnte ich einen genetischen und einen epigenetischen Marker identifizieren, welcher potentiell unter Selektion stehen könnte. Allerdings bestätigten die Ergebnisse dieser Studie erneut, dass DNA-Methylierung bei S. canadensis kaum in die Anpassung an das neue Verbreitungsgebiet involviert zu sein scheint. Schließlich führte ich eine dritte Studie durch, in welcher ich Samen kurzlebiger Pflanzenarten reziprok zwischen zwei klimatisch unterschiedlichen Regionen in Deutschland transplantierte, um lokale Anpassung auf Ebene der Pflanzenfamilien zu untersuchen. Zu diesem Zweck nutze ich vier Pflanzenfamilien (Amaranthaceae, Asteraceae, Plantaginaceae, Solanaceae), wobei ich hier auch zwischen nicht-heimischen und heimischen Pflanzenarten verglich. Beide Regionen lagen mehr als 600 Kilometer voneinander entfernt und wiesen entweder ein gemäßigt-ozeanisches oder gemäßigt-kontinentales Klima auf. In dieser Studie zeigte sich für einige—sowohl nicht-einheimische als auch einhimische—Arten eine Fehlanpassung an die eigenen lokalen Bedingungen. In demethylierten Individuen der untersuchten Pflanzenarten wirkte sich die DNA-Methylierung widersprüchlich, aber artspezifisch auf das Überleben und die Biomasseproduktion aus. Die Ergebnisse dieser Studie unterstreichen, dass DNA-Methylierung einen vernachlässigbaren Beitrag zur lokalen Anpassung bei den untersuchten nicht-heimischen, aber auch einheimischen Arten leistete. Zusammenfassend konnte ich mit dieser Arbeit festellen, dass DNA-Methylierung bei nicht-einheimischen Pflanzenarten eine untergeordnete Rolle sowohl bei der adaptiven Merkmalsvariation entlang von Klimagradienten als auch der lokalen Anpassung an klimatisch unterschiedliche Regionen spielt, wenn diese Pflanzenarten eine hohe genetische Vielfalt aufweisen und sich hauptsächlich sexuell vermehren. Ich konnte zeigen, dass der Anpassungserfolg dieser nicht-einheimischen Pflanzenarten kaum durch DNA-Methylierung erklärbar ist, sondern vielmehr eine mögliche Folge mehrfacher Eintragungen, von Ausbreitungskorridoren und Meta-Populationsdynamiken sein könnte. Die Ergebnisse dieser Studien verdeutlichen ebenso, dass die Verwendung von Pflanzenarten, die sich nicht überwiegend klonal vermehren und keine genetischen Modellpflanzen sind, unerlässlich ist, um die Effektstärke epigenetischer Mechanismen im ökologisch-evolutionären Kontext zu charakterisieren.

T1 - Leptospira genomospecies and sequence type prevalence in small mammal populations in Germany JF - Vector-Borne and Zoonotic Diseases N2 - Leptospirosis is a worldwide emerging infectious disease caused by zoonotic bacteria of the genus Leptospira. Numerous mammals, including domestic and companion animals, can be infected by Leptospira spp., but rodents and other small mammals are considered the main reservoir. The annual number of recorded human leptospirosis cases in Germany (2001-2016) was 25-166. Field fever outbreaks in strawberry pickers, due to infection with Leptospira kirschneri serovar Grippotyphosa, were reported in 2007 and 2014. To identify the most commonly occurring Leptospira genomospecies, sequence types (STs), and their small mammal host specificity, a monitoring study was performed during 2010-2014 in four federal states of Germany. Initial screening of kidney tissues of 3,950 animals by PCR targeting the lipl32 gene revealed 435 rodents of 6 species and 89 shrews of three species positive for leptospiral DNA. PCR-based analyses resulted in the identification of the genomospecies L. kirschneri (62.7%), Leptospira interrogans (28.3%), and Leptospira borgpetersenii (9.0%), which are represented by four, one, and two STs, respectively. The average Leptospira prevalence was highest (approximate to 30%) in common voles (Microtus arvalis) and field voles (Microtus agrestis). Both species were exclusively infected with L. kirschneri. In contrast, in bank voles (Myodes glareolus) and yellow-necked mice (Apodemus flavicollis), DNA of all three genomospecies was detected, and in common shrews (Sorex araneus) DNA of L. kirschneri and L. borgpetersenii was identified. The association between individual infection status and demographic factors varied between species; infection status was always positively correlated to body weight. In conclusion, the study confirmed a broad geographical distribution of Leptospira in small mammals and suggested an important public health relevance of common and field voles as reservoirs of L. kirschneri. Furthermore, the investigations identified seasonal, habitat-related, as well as individual influences on Leptospira prevalence in small mammals that might impact public health.

Rickettsiae are obligately intracellular bacteria transmitted by arthropod vectors. The ecology of Rickettsia species has not been investigated in detail, but small mammals are considered to play a role as reservoirs. Aim of this study was to monitor rickettsiae in wild small mammals over a period of five years in four federal states of Germany. Initial screening of ear pinna tissues of 3939 animals by Pan-Rick real-time PCR targeting the citrate synthase (gltA) gene revealed 296 rodents of seven species and 19 shrews of two species positive for rickettsial DNA. Outer membrane protein gene (ompB, ompAIV) PCRs based typing resulted in the identification of three species: Rickettsia helvetica (90.9%) was found as the dominantly occurring species in the four investigated federal states, but Rickettsia felis (7.8%) and Rickettsia raoultii (1.3%) were also detected. The prevalence of Rickettsia spp. in rodents of the genus Apodemus was found to be higher (approximately 14%) than in all other rodent and shrew species at all investigated sites. General linear mixed model analyses indicated that heavier (older) individuals of yellow-necked mice and male common voles seem to contain more often rickettsial DNA than younger ones. Furthermore, rodents generally collected in forests in summer and autumn more often carried rickettsial DNA. In conclusion, this study indicated a high prevalence of R. helvetica in small mammal populations and suggests an age-dependent increase of the DNA prevalence in some of the species and in animals originating from forest habitats. The finding of R. helvetica and R. felis DNA in multiple small mammal species may indicate frequent trans-species transmission by feeding of vectors on different species. Further investigations should target the reason for the discrepancy between the high rickettsial DNA prevalence in rodents and the so far almost absence of clinical apparent human infections.

Applying the nonlinear Blinder-Oaxaca decomposition technique, we find that the main factors driving these changes in the overall level of self-employment are demographic developments, the shift towards service sector employment and a larger share of population holding a tertiary degree. While these factors explain most of the development in self-employment with employees and the overall level of self-employment in West Germany, their explanatory power is much lower for the stronger increase in solo self-employment and in self-employment in former socialist East Germany.

Primarily through qualitative data and document analysis, this article compares the restructuring of labour market service delivery in the UK and Germany. The comparison suggests the emergence of complex governance arrangements that seek to balance public regulation and accountability with the creation of room for market competition. As a result, we can observe in both countries a greater use of markets, but also of rules. While in both countries the relationships between different providers of labour market services can best be described as a mixture of cooperation and competition, differences exist in terms of instruments and the comprehensiveness of coordination initiatives.

Based on case studies, the authors analyze the appropriateness of the performance information provided in the newly established performance budgets of municipalities in Germany and Italy. They also examine the interest of politicians and senior managers in using such information for decision-making and monitoring within the municipal budget cycle. They find that the use of performance information is generally quite modest, and that the interest of different local actors varies to a great extent. Politicians are generally less interested in such information than top managers, particularly chief financial officers. The results are discussed by applying a theoretical framework based on institutional and legitimacy theories, and are compared with the literature on performance information use.

This 2016 version of the national seismic hazard assessment for Germany is based on a comprehensive involvement of all accessible uncertainties in models and parameters and includes the provision of a rational framework for integrating ranges of epistemic uncertainties and aleatory variabilities in a comprehensive and transparent way. The developed seismic hazard model incorporates significant improvements over previous versions. It is based on updated and extended databases, it includes robust methods to evolve sets of models representing epistemic uncertainties, and a selection of the latest generation of ground motion prediction equations. The new earthquake model is presented here, which consists of a logic tree with 4040 end branches and essential innovations employed for a realistic approach. The output specifications were designed according to the user oriented needs as suggested by two review teams supervising the entire project. Seismic load parameters, for rock conditions of nu(S30) = 800 m/s, are calculated for three hazard levels (10, 5 and 2% probability of occurrence or exceedance within 50 years) and delivered in the form of uniform hazard spectra, within the spectral period range 0.02-3 s, and seismic hazard maps for peak ground acceleration, spectral response accelerations and for macroseismic intensities. Results are supplied as the mean, the median and the 84th percentile. A broad analysis of resulting uncertainties of calculated seismic load parameters is included. The stability of the hazard maps with respect to previous versions and the cross-border comparison is emphasized.

When the Science of Judaism (Wissenschaft des Judentums) evolved at the beginning of the nineteenth century, it intended, through both theological and secular studies, to demonstrate the general value of Jewish culture and civilization. Although denied a place in the public university system until after the Shoah, Jewish Studies departments have since been established at various German universities, and, in 2013, the School of Jewish Theology of the University of Potsdam was opened as the first Jewish divinity school in the history of the German university system. With this, what was once a utopian dream became a reality, and both branches of the Science of Judaism, religious and secular, became undisputed parts of the German academic scene, using similar tools for differing aims. Two prime examples of the intersection of the secular and religious in Germany today are the proliferation of divinity schools at state universities, on the one hand, and the development of military chaplaincy in the armed forces, on the other. Both of these, through contractual agreements, aim to regulate and facilitate religious pluralism within a secular state. While the one has already begun to take place, the other is currently under discussion.

The main objective of the present study is to project climate change impacts on the seasonal dynamics of water fluxes, spatial changes in water balance components as well as the future flood and low flow conditions in Germany. This study is based on the modeling results of the process-based eco-hydrological model SWIM (Soil and Water Integrated Model) driven by various regional climate scenarios on one hand. On the other hand, it is supported by statistical analysis on long-term trends of observed and simulated time series. In addition, this study evaluates the impacts of potential land use changes on water quality in terms of NO3-N load in selected sub-regions of the Elbe basin. In the context of climate change, the actual evapotransipration is likely to increase in most parts of Germany, while total runoff generation may decrease in south and east regions in the scenario period 2051-2060. Water discharge in all six studied large rivers (Ems, Weser, Saale, Danube, Main and Neckar) would be 8 – 30% lower in summer and autumn compared to the reference period (1961 – 1990), and the strongest decline is expected for the Saale, Danube and Neckar. The 50-year low flow is likely to occur more frequently in western, southern and central Germany after 2061 as suggested by more than 80% of the model runs. The current low flow period (from August to September) may be extended until the late autumn at the end of this century. Higher winter flow is expected in all of these rivers, and the increase is most significant for the Ems (about 18%). No general pattern of changes in flood directions can be concluded according to the results driven by different RCMs, emission scenarios and multi-realizations. An optimal agricultural land use and management are essential for the reduction in nutrient loads and improvement of water quality. In the Weiße Elster and Unstrut sub-basins (Elbe), an increase of 10% in the winter rape area can result in 12-19% more NO3-N load in rivers. In contrast, another energy plant, maize, has a moderate effect on the water environment. Mineral fertilizers have a much stronger effect on the NO3-N load than organic fertilizers. Cover crops, which play an important role in the reduction of nitrate losses from fields, should be maintained on cropland. The uncertainty in estimating future high flows and, in particular, extreme floods remain high due to different RCM structures, emission scenarios and multi-realizations. In contrast, the projection of low flows under warmer climate conditions appears to be more pronounced and consistent. The largest source of uncertainty related to NO3-N modelling originates from the input data on the agricultural management. N2 - Wasserressourcen werden in Quantität und Qualität von Veränderungen in der Umwelt, insbesondere von Änderungen des Klimas und der Landnutzung, in signifikantem Maße beeinflusst. In dieser Arbeit wurden die Auswirkungen von Klimavariabilität und Klimawandel auf die Wasserressourcen und Extremereignisse wie Hoch- und Niedrigwasser in Deutschland untersucht. Die Analyse erfolgte auf der einen Seite modellgestützt, wobei die Ergebnisse aus verschiedenen regionalen Klimamodellen durch ein ökohydrologisches Modell in Änderungen in den hydrologischen Prozessen transformiert wurden, zum anderen aber auch datengestützt, z.B. durch die statistische Interpretation von beobachteten und simulierten Zeitreihen. Zusätzlich wurden die Auswirkungen von Landnutzungsänderungen auf Umsatz von Stickstoff in der Landschaft und im Wasser untersucht, wobei dasselbe ökohydrologische Modell zum Einsatz kam. Im Rahmen des Klimawandels wird zur Mitte dieses Jahrhunderts die aktuelle Evapotranspiration in den meisten Teilen Deutschlands mit großer Wahrscheinlichkeit zunehmen. Die täglichen Abflussmengen der fünf größten Flussgebiete in Deutschland (Ems, Weser, Elbe, Obere Donau und Rhein) werden dieser Untersuchung zur Folge im Sommer und Herbst um 8%-30% geringer sein als in der Referenzperiode (1961-1990). 80% der Szenariensimulationen stimmen darin überein, dass die 50-jährigen Niedrigwasserereignisse zum Ende dieses Jahrhunderts mit großer Wahrscheinlichkeit häufiger in den westlichen, den südlichen und den zentralen Teilen Deutschlands auftreten werden. Die gegenwärtige Niedrigwasserperiode (August-September) könnte sich zudem dann bis in den späten Herbst ausweiten. Für alle Flüsse werden höhere Winterabflüsse erwartet, wobei diese Zunahme für die Ems am stärksten ausfällt (ca. 18%). Mit größerer Unsicherheit sind dagegen die Aussagen zur Entwicklung der Hochwasser behaftet. Aus den Ergebnissen, die durch unterschiedliche regionale Klimamodelle und Szenarien getrieben wurden, kann jedoch kein allgemeingültiges Muster für die Änderungen der 50-jährigen Hochwässer ausgemacht werden. Eine optimierte Landnutzung und ein optimiertes Landmanagement sind für die Reduzierung der NO3-Einträge in die Oberflächengewässer essentiell. In den Einzusgebieten der Weißen Elster und der Unstrut (Elbe) kann eine Zunahme von 10% in der Anbaufläche von Winterraps zu einer 12-19% höheren NO3 Fracht führen. Mais, eine weitere Energiepflanze, hat hingegen einen mäßigeren Effekt auf die Oberflächengewässer. Die Höhe der Gabe von mineralischen Düngern beeinflußt zudem in starkem Maße die Nitratbelastung von Flüssen. Zwischenfrüchte können den NO3-Austrag im Sommer zusätzlich erheblich verringern. Insgesamt bleibt die Unsicherheit in der Vorhersage von Spitzenabflüssen und im Besonderen von Extrem-Hochwässern als Folge unterschiedlicher regionaler Klimamodelle, Emissionsszenarien und Realisationen sehr hoch. Im Gegensatz dazu erscheinen die Projektionen zu den Niedrigwasserereignissen unter wärmeren Bedingungen sehr viel deutlicher und einheitlicher. Die größte Unsicherheit in der Modellierung von NO3 dagegen sind die Eingangsdaten z.B. für das lokale landwirtschaftliche Management.

So far, only few studies have taken this approach, and, in particular, no such assessments exist for Germany, the most populated country of Europe. Methods: We assess temperature-related mortality in 12 major German cities based on daily time-series of all-cause mortality and daily mean temperatures in the period 1993-2015, using distributed-lag non-linear models in a two-stage design. Resulting risk functions are applied to estimate excess mortality in terms of GMT rise relative to pre-industrial levels, assuming no change in demographics or population vulnerability. Results: In the observational period, cold contributes stronger to temperature-related mortality than heat, with overall attributable fractions of 5.49% (95%CI: 3.82-7.19) and 0.81% (95%CI: 0.72-0.89), respectively. Future projections indicate that this pattern could be reversed under progressing global warming, with heat-related mortality starting to exceed cold-related mortality at 3 degrees C or higher GMT rise. Across cities, projected net increases in total temperature-related mortality were 0.45% (95%CI: -0.02-1.06) at 3 degrees C, 1.53% (95%CI: 0.96-2.06) at 4 degrees C, and 2.88% (95%CI: 1.60-4.10) at 5 degrees C, compared to today's warming level of 1 degrees C. By contrast, no significant difference was found between projected total temperature-related mortality at 2 degrees C versus 1 degrees C of GMT rise. Conclusions: Our results can inform current adaptation policies aimed at buffering the health risks from increased heat exposure under climate change. They also allow for the evaluation of global mitigation efforts in terms of local health benefits in some of Germany's most populated cities.

Neben den allgemeinen Gegebenheiten des Marktes werden vor allem die Finanzierungsbedingungen sowie das Investitionsverhalten einzelner Beteiligungsgesellschaften analysiert. In den Jahren 2008 - 2009 zeigt sich einerseits eine weitestgehend unveränderte Struktur der Refinanzierungsquellen. Privatpersonen und Banken sowie der öffentliche Sektor nehmen weiterhin einen hohen Stellenwert ein. Andererseits werden deutliche Veränderungen der strukturellen Merkmale, wie auch im Investitionsverhalten einzelner Beteiligungsgesellschaften deutlich. Besonders auffällig für die Branche sind das Rationalisierungsbestreben beim Einsatz von Investmentmanagern sowie die zunehmende Spätphasenspezialisierung. Aus dem festgestellten Konsolidierungs- und Reifeprozess erwächst die Herausforderung und offene Frage, wie der Markt eine solche strukturelle Angebotslücke im Frühphasensegment begegnen will. Auch das Einwerben neuer Finanzmittel sowie die aktuellen Exit-Bedingungen werden in der vorliegenden Studie kritisch beleuchtet. Als ein reizvolles Instrument zur Reduzierung der aufgezeigten Problemfelder wird dabei die aktuell unterentwickelte Syndizierung von Beteiligungsinvestitionen angesehen. Die effizientere Ausgestaltung derartiger Finanzierungsstrukturen sollte dazu beitragen, dass das private Beteiligungskapital künftig stärker bei der Transformation betrieblicher Forschung und Entwicklung zum Einsatz gelangt. N2 - This paper presents another in a continuing research program initiated at the University of Potsdam in 2001. The current study surveys the current status of the German private equity market. The effects of the financial crisis generally, especially their consequences for the financial conditions and investment strategies of private equity firms are examined. On the one hand, the paper observes little change in the refinancing structure during 2008-2009. Private individuals, banks and the public sector still play an important role. On the other hand, changes in structural characteristics of the investment companies as well as in their investment behaviors are significant. Most noticeable are attempts to reduce human resource costs and a shift towards greater late-stage investment. Apparent consolidation and developing maturity portend a future challenge, to ameliorate an emerging structural supply gap in earlystage segment. In addition, the paper critically examines the current condition of fundraising activities and exit conditions. Syndication, though underdeveloped at present, might offer one way to address these troubling issues. More efficient financing structures should allow private equity to play an increasing role in the commercial transformation of corporate research and development.

Im Fokus stehen die Verfügbarkeit konkreter Finanzierungsinstrumente für KMU und deren Akzeptanz im Mittelstand. Dies soll die derzeitigen Möglichkeiten und Grenzen des heimischen Banken- und Finanzsystems verdeutlichen. Darüber hinaus werden verschiedene Aspekte des Innovationsverhaltens der befragten Unternehmen beleuchtet. Es zeigt sich, dass die Finanzierung aus erwirtschafteten Gewinnen einen überragenden Stellenwert besitzt. Zudem werden neben dem traditionell verankerten Bankdarlehen, vor allem kurzfristige, flexible, aber teure Kontokorrent- und Lieferantenkredite für Investitionszwecke genutzt. Alternative Finanzierungsinstrumente, wie Mezzanine, Beteiligungskapital sowie auch Kapitalmarktfinanzierungen haben bisher nur eine marginale Bedeutung erlangt. Als mögliche Ursachen hierfür sind mangelnde Kenntnisse und persönliche Vorbehalte auf Unternehmensseite, aber auch die grundsätzliche Nichteignung dieser Alternativen festzustellen. So liegt das nachgefragte Finanzierungsvolumen bei KMU häufig unter den Mindestgrenzen derartiger Kapitalgeber. Staatliche Förderinstrumente, welche vor allem von größeren mittelständischen Unternehmen in Anspruch genommen werden, können dabei nur einen Teilbeitrag leisten, um die Finanzierungsrestriktionen zu reduzieren. Im Bereich der Innovationsfinanzierung zeigt sich daher vor allem bei mittelgroßen Projekten ein besonderer Finanzierungsengpass. N2 - This study analyzes the results of a nationwide survey on the corporate financing behavior of German SMEs. The availability of specific financial instruments for SMEs and their acceptance from an entrepreneurial perspective is investigated. Therefore, the current possibilities and limitations of the domestic banking and financial system are illustrated. Moreover, various aspects of the innovation behaviour of the companies are highlighted. It is shown that funding from earned profits has an outstanding importance. Furthermore, beside the traditional Bank loan, especially the short-term, flexible but also expensive overdraft and supplier credit are frequently used for investment purposes. Yet alternative financing capital such as mezzanine, private equity as well as capital market financing instruments had only a marginal importance. Possible reasons for these findings are on the one hand a lack of knowledge and personal reservations from the entrepreneurial perspective. On the other hand, a general unsuitability of these alternatives partially is noted, e.g. the funding volume from SMEs is often below the requested minimum limits of these alternatives. State subsidies, which are taken mainly from larger SMEs, can only make a partial contribution to reduce these financing constraints. Finally, a special funding shortfall is highlighted for medium-sized project´s in the field of innovation financing.

Understanding the dynamics of institutional change therefore requires an examination of the interplay of changes in formal institutional rules and how organizations respond to these changes by strategic attempts to promote or hinder further change in institutions. The macro-level political story of institutional change shows a number of paradoxes resulting in unexpected and often incomplete forms of market liberalization shaped by continued support for some core features of Germany's social market economy. The resulting erosion of Germany's co-ordinated model of economic organization through networks and business associations has gone hand-in-hand with the attempts to preserve these institutions for core workers and sectors of the economy in the face of changing environments. The result is a more varied institutional landscape characterized by international diffusion of liberal policies and the politics of their variable re-embedding within a long-term path of institutional continuity.

Methods: This study included 32,182 patients over the age of 65 years who received benzodiazepine prescriptions for the first time between January 2010 and December 2014 in general and neuropsychiatric practices in Germany. Follow up lasted until July 2016. The main outcome measure was the proportion of patients treated with benzodiazepines for >6 months. Results: The proportion of patients with benzodiazepine therapy for >6 months increased with age (65-70 years: 12.3%; 71-80 years: 15.5%; 81-90 years: 23.7%; >90 years: 31.6%) but did not differ significantly between men (15.5%) and women (17.1%). The proportion of patients who received benzodiazepines for >6 months was higher among those with sleep disorders (21.1%), depression (20.8%) and dementia (32.1%) than among those with anxiety (15.5%). By contrast, this proportion was lower among people diagnosed with adjustment disorders (7.7%) and back pain (3.8%). Conclusion: Overall, long-term use of benzodiazepines is common in older people, particularly in patients over the age of 80 and in those diagnosed with dementia, sleep disorders, or depression.

Nevertheless, up-to-date empirical studies on this issue are lacking. This paper investigates the presumption, that in recent years top bureaucrats have become more politicised, while at the same time more politicians stem from a bureaucratic background, by looking at the career paths of both. For this purpose, we present new empirical evidence on career patterns of top bureaucrats and executive politicians both at Federal and at Länder level. The data was collected from authorized biographies published at the websites of the Federal and Länder ministries for all Ministers, Parliamentary State Secretaries and Administrative State Secretaries who held office in June 2009.

We discuss the German adaption of the Identity Project, an 8-week school-based ethnic-racial identity exploration intervention developed in the United States. We use this as a concrete example of how we thought through the focal construct of ERI to figure out how and whether it is a salient social identity category for youth in Germany where, in response to the history of racially motivated genocide, discussions of "race" are taboo. Digging into the ways ERI may not be directly transferable to different contexts can help us understand its nature as a socially constructed identity with real-life implications. Our hope with this paper is to further discussion, question our conceptualizations, and acknowledge how a detailed understanding of sociohistorical contexts is needed for the study of ERI.

The longitudinal study followed 639 adolescents in Germany (65% of immigrant descent, 50% female, M-age = 12.35 years, SDage = .69) from 7(th) grade (pre-intervention at T1, five to six months post-intervention at T2) to the end of 8(th) grade (one-year follow-up at T3). We tested for direct and moderated (by heritage group, discrimination, classroom cultural diversity climate) effects using regression and latent change models. The self-affirmation intervention did not promote grades or math competence. However, in the short-term and for adolescents of immigrant descent, the intervention prevented a downward trajectory in mastery reactions to academic challenges for those experiencing greater discrimination. Further, it protected against a decline in behavioral school engagement for those in positive classroom cultural diversity climates. In the long-term and for all adolescents, the intervention lessened an upward trajectory in disruptive behavior. Overall, the self-affirmation intervention benefited some aspects of school-related adjustment for adolescents of immigrant and non-immigrant descent. The intervention context is important, with classroom cultural diversity climate acting as a psychological affordance enhancing affirmation effects. Our study supports the ongoing call for theorizing and empirically testing student and context heterogeneity to better understand for whom and under which conditions this intervention may work.

We used a longitudinal, wait-list control design pooling eight classrooms across the school years of 2018-2019 and 2019-2020. The sample included 195 seventh graders (M-age = 12.35 years, SD =.79, 39% female, 83% of migration background). Findings showed moderate support for more heritage identity exploration and greater perceptions of unequal treatment and critical consciousness climate in the intervention group. There were also important differences across conditions regarding how identity and climate related to adolescent outcomes. We conclude that the Identity Project can be adapted and applied in other cultural contexts such as Germany. It provides a necessary space for adolescents to engage in discussions about diversity, cultural heritage, social inequities, and their relevance to one's identities.

German schools adopted this movement in 1995. Decades later, racism is not yet a strong developmental science research topic for studies of youth in Germany and Europe. In this commentary we argue that it should be. With increasing hate crimes and harassment, there is also a need to understand how families are socializing young people to be prepared for, cope with, resist, and disrupt racism. This type of ethnic-racial socialization affects important developmental processes-adolescent ethnic-racial identity development and intergroup and institutional understanding and relations-and requires a more prominent place of study in a migration-diverse Germany. Studying these issues in this particular sociohistorical context will also contribute to a more context-specific understanding of youth experiences of racism.

Latent profile analysis yielded three configurations of risk factors, made up of a non-risk group, a risk group scoring high on measures of social rejection (SR), and a risk group scoring high on measures of affiliation with aggressive peers and academic failure (APAF). Latent path analysis revealed that, as predicted, only membership in the SR group at T1 predicted reactive aggression at T2 17 months later. By contrast, only membership in the APAF group at T1 predicted proactive aggression at T2.

Whereas past research has focused on social reinforcement mechanisms as the underlying processes, the present longitudinal study analysed the role of external control beliefs as an additional mediator explaining the link between peers’ acceptance of aggression and the development of aggressive behaviour. Drawing on a large community sample of N = 1,466 male and female children and adolescents from Germany aged between 10 and 18 years, results of latent structural equation modeling were consistent with the hypotheses that peer acceptance of aggression would predict external control beliefs in the social domain, which in turn, should predict aggressive behaviour over time. Additional multigroup analyses showed that the predicted pathways were consistent across gender and age groups.
