Magister ludens: Der Erzähler in Heinrich Wittenweilers "Ring"

In this closely argued and admirably lucid study of the late medieval didactic epic "Der Ring", Christa Wolf Cross analyzes the dynamics of the narrator-reader relationship. Wittenweiler's narrator presents himself at times as the omniscient and methodical teller of his tale, an authoritative teacher in command both of his material and his audience, and at other points as a playful master who feigns ignorance, appears to mock his own versifying, and challenges the reader to become vigilant to an extraordinary degree and to recognize that he must judge independently what to accept as Wittenweiler's teachings. Cross's investigation leads her to propound new answers to a number of questions that have long perplexed Wittenweiler scholars. While she has much to say to other specialists, her study addresses itself not to them alone but to a larger audience of students of medieval literature as well

Spectral cinema from a phantom state: film aesthetics and the politics of identity in Divided Heaven and Solo Sunny

In this essay I draw on close textual analysis to consider the interface between film aesthetics and the politics of identity in Konrad Wolf’s Der geteilte Himmel / Divided Heaven (1964) and Solo Sunny (1979). Both films focus on women who have to confront painful processes of self realisa-tion in specifically East German contexts. They also show Wolf and his collaborators working in two very different modes, from a nouvelle vague-inspired mix of location shooting and self-conscious formal artifice to a more laconic style and mobile camera that borrow from documentary aesthetics. Viewed from the perspective of today, the films resist the reductive stereotyping of what Christa Wolf in 1991 called the 'phantom' East Germany, and offer a more productive haunting. As living ghosts in the post-reunification era, they are a reminder of the necessity of remembering, and so confound both a negative 'master narrative' of the GDR and a collective amnesia with no interest in this history

Risk of contralateral second primary breast cancer according to hormone receptor status in Germany

Introduction: Hormone receptor (HR) status has become an established target in treatment strategies of breast cancer. Population-based estimates of contralateral breast cancer (CBC) incidence by HR subtype in particular are limited. The aim of this study was to provide detailed data on CBC incidence for Germany. Methods: Invasive breast cancer data were extracted on 49,804 women yielding 594 second primaries from the cancer registries of the Federal States of Brandenburg and Saarland and the area of Munich for the period from 1998 to 2007. Multiple imputation was used on missing values for HR status. We estimated standardized incidence ratios (SIRs) with 95% confidence intervals (95% CIs). Results: SIR estimates of CBC among women diagnosed with an invasive first primary breast cancer (FBC) of any HR subtype ranged from 1.0 to 1.5 in the three registries. Pooling three registries' data, the SIR of HR-positive CBC was 0.7 (95% CI: 0.6 to 0.8) among women with HR-positive FBC. For those women with HR-negative FBC, the SIR of HR-negative CBC was 8.9 (95% CI: 7.1 to 11.1). Among women with FBC diagnosed before the age of 50 years, incidence of CBC was increased, especially for HR-negative FBC (SIR: 9.2; 95% CI: 7.1 to 11.9). Conclusions: HR status of the first primary and age at first diagnosis is relevant for predicting risk of CBC. Particularly, patients with HR-negative FBC had elevated risks

DFT Calculations of Isotropic Coupling Constants of Phenoxyl and Aroxyl Radicals

Hybrid density-functional calculations were carried out to corroborate the identity of phenoxyl radicals observed by EPR spectroscopy after oxidation of selected mono- and polyphenols with horseradish peroxidase/hydrogen peroxide or after alkaline autoxidation. Whereas quantitative correlations of experimental and theoretical coupling constants were less satisfactory, we could confirm formation of a bi-radical after initial oxidation of 2,4,6-trimethylphenol, the mesomeric structures of gallate ester aroxyl radicals and identify the radical site of a model gallotannin, hamamelitannin

Hourly exposure to ultrafine particle metrics and the onset of myocardial infarction in Augsburg, Germany

BACKGROUND: Epidemiological evidence on the health effects of ultrafine particles (UFP) remains insufficient to infer a causal relationship that is largely due to different size ranges and exposure metrics examined across studies. Moreover, evidence regarding the association between UFP and cardiovascular disease at a sub-daily timescale is lacking.OBJECTIVE: We investigated the relationship between different particle metrics, including particle number (PNC), length (PLC), and surface area (PSC) concentrations, and myocardial infarction (MI) at an hourly timescale.METHODS: We collected hourly air pollution and meteorological data from fixed urban background monitoring sites and hourly nonfatal MI cases from a MI registry in Augsburg, Germany, during 2005-2015. We conducted a time-stratified case-crossover analysis with conditional logistic regression to estimate the association between hourly particle metrics and MI cases, adjusted for air temperature and relative humidity. We also examined the independent effects of a certain particle metric in two-pollutant models by adjusting for copollutants, including particulate matter (PM) with an aerodynamic diameter of >= 10 mu m or 2.5 mu m (PM10 and PM2.5, respectively), nitrogen dioxide, ozone, and black carbon.RESULTS: Overall, a total of 5,898 cases of nonfatal MI cases were recorded. Exploratory analyses showed similar associations across particle metrics in the first 6-12 h. For example, interquartile range increases in PNC within the size range of 10-100 nm, PLC, and PSC were associated with an increase of MI 6 h later by 3.27% [95% confidence interval (CI): 0.27, 6.37], 5.71% (95% CI: 1.79, 9.77), and 5.84% (95% CI: 1.04, 10.87), respectively. Positive, albeit imprecise, associations were observed for PNC within the size range of 10-30 nm and 100-500 nm. Effect estimates for PLC and PSC remained similar after adjustment for PM and gaseous pollutants.CONCLUSIONS: Transient exposure to particle number, length, and surface area concentrations or other potentially related exposures may trigger the onset of nonfatal myocardial infraction

The selection and definition of indicators in public health monitoring for the 65+ age group in Germany

Selecting relevant indicators is an important step in the development of public health monitoring for older people. Indicators can be used to combine information comprehensively from various data sources and enable recurring, comparable findings to be made about the health of older people. Indicators were systematically compiled from existing international monitoring systems. An indicator set on health in old age was developed using a multistage, structured consensus-based process together with an interdisciplinary panel of experts. The resulting 18 indicators were assigned to three health areas: (1) environmental factors, (2) activities and participation, and (3) personal factors. Data sources that can be used for the indicators are the health surveys within the framework of the Robert Koch Institute’s (RKI) health monitoring system, as well as surveys from other research institutes and official statistics. In the future, the indicator set is to be developed further and integrated into an overall approach that is geared towards health reporting and the monitoring of chronic diseases in all phases of life
