We continue our review of issues related to measurement error and misclassification in epidemiology. further describe methods adjusting for biased estimation caused by continuous covariates, covering likelihood methods, Bayesian moment reconstruction, moment‐adjusted imputation, multiple imputation. then which can also be used with categorical covariates. Methods distributions variables are reviewed. Illustrative examples provided throughout these sections. provide lists available software...
Background: Despite reductions in exposure for workers and the general public, radon remains a leading cause of lung cancer. Prior studies underground miners depended heavily upon information on deaths among employed early years mine operations when exposures were high tended to be poorly estimated. Objectives: To strengthen basis radiation protection, we report follow-up later periods whom have more accurate accrued at intensities that are comparable contemporary settings. Methods: We...
The Pooled Uranium Miners Analysis (PUMA) study draws together information from cohorts of uranium miners Canada, the Czech Republic, France, Germany and USA.
Objectives Radon is a ubiquitous occupational and environmental lung carcinogen. We aim to quantify the association between radon progeny cancer mortality in largest most up-to-date pooled study of uranium miners. Methods The miners analysis combines 7 cohorts male with 7754 deaths 4.3 million person-years follow-up. Vital status were ascertained 1946 2014. cumulative exposure working level months (WLM) was modelled as excess relative rate (ERR) per 100 WLM using Poisson regression;...
Abstract The Pooled Uranium Miners Analysis (PUMA) study is the largest uranium miners cohort with 119,709 miners, 4.3 million person-years at risk and 7754 lung cancer deaths. Excess relative rate (ERR) estimates for mortality per unit of cumulative exposure to radon progeny in working level months (WLM) based on PUMA have been reported. ERR/WLM was modified by attained age, time since or age exposure, rate. This pattern found full 1960 + sub-cohort, i.e., hired later chronic low exposures...
Many British newspapers proclaim strongly partisan political and moral positions, with headlines such as "Get Britain out of the EU." In contrast, German newspapers, during national events refugee crisis, often take on role reflective observers. Previous comparative research has shown a link between journalists' output professional attitudes. Using data from Worlds Journalism Study, this article analyses attitudes journalists (N = 1475) across three constituents journalism culture: societal,...
UNSCEAR recently recommended that future research on the lung cancer risk at low radon exposures or exposure rates should focus more contemporary uranium miners. For this purpose, models in German Wismut cohort of miners were updated extending follow-up period by 5 years to 1946-2018. The full (n = 58,972) and specifically 1960 + sub-cohort first hired later 26,764) analyzed. is characterized protracted high quality measurements. Internal Poisson regression was used estimate excess relative...
Abstract The ultrafine particle measurements in the Augsburger Umweltstudie, a panel study conducted Augsburg, Germany, exhibit measurement error from various sources. Measurements of mobile devices show classical possibly individual–specific error; Berkson–type error, which may also vary individually, occurs, if fixed monitoring stations are used. combination site and individual exposure results mixture two types. We extended existing bias analysis approaches to linear mixed models with...
From 1946 to 1990, more than 400 000 people were employed by Wismut AG, a Soviet/Soviet-German corporation (German abbreviation: SAG/ SDAG), in the East German states of Saxony and Thuringia. In early years particular, employees exposed large amounts radon respirable crystalline silica.In cohort 35 204 former underground mortality was analyzed comparison general male population Germany, pertaining standardized ratios (SMRs) calculated.18 510 persons study died follow-up period 1960-2013....

Contemporary human geography shows an increased interest in social theory, and this is especially true for German-speaking geographers. The conference series "Neue Kulturgeographie" e. g. has had the effect to promote a debate on paradigms epistemologies, which gone beyond constructivist poststructuralist approaches. This also contributed popularity of ideas Pierre Bourdieu can be summed up as "theory practice". Against background, paper provides thematic overview works that rely explicitly...
Abstract. Within the academic field of Geography, there is an "identity crisis" facing German-language scholarship in Development Studies programs, particularly terms disciplinary characteristics, epistemological aims and methodological approaches. This critical self-reflection finds its expression use like "mid-range theory" or "global south", manifest as well repeated calls for a re-formulation discipline. Simultaneously, increasing number empirical studies this are informed by readings...
The experience of "meaning in life" (MiL) is a major aspect life satisfaction and psychological well-being. To assess this highly individual construct, idiographic measures with open-response formats have been developed. However, it can be challenging to categorize these experiences for interindividual comparisons. Our study aimed derive MiL categories from listings develop an integrative model.University students were asked rate 58 providing aspects recently found nationwide using the...
