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.

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.

T1 - Naming and war in modern Germany JF - Names : a journal of onomastics N2 - This paper analyzes naming behavior in Germany in the context of rapid social change. It begins with an overview of general developments in naming in Germany over the last one hundred years, based on data from the German Socio-Economic Panel Study (SOEP), which supplies us with almost 45,000 datasets. The paper focuses on the periods of World War II and the Cold War since we conclude that general developments in naming were disrupted by these two phenomena. Wartime brings accelerated social change in its wake and people react to this social change - often on an apparently individual level. Here, our findings are in accordance with established sociological theories.

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.
