A controversy on moral judgment: Fifteen historian-reviewers in the controversy on Hannah Arendt’s book Eichmann in Jerusalem in the US, West Germany and France, 1963-1967. A historical and a pragma-dialectical perspective
This dissertation consists of two parts. The first part is the result of thorough historical research into the development and content of the discussion of Hannah Arendt’s book ‘Eichmann in Jerusalem’ between 1963 and 1967, in three countries: the US, West Germany and France. This part corrects and enhances the historiography of the controversy on several important points. The second part looks specifically at the participation of fifteen historian-reviewers in the debate. These fifteen texts were analysed with help of the pragma-dialectical argumentation theory and method. The first result of this is a structured presentation of the precise differences of opinion between Arendt and the fifteen reviewers, and of the arguments that keep recurring in their discussion. Secondly, these textual analyses provide insight into the procedural problems that can occur in a heated discussion of the Holocaust, as well as the ways that discussants attempt to overcome these obstacles. These results are starting points for further research into the problematic nature of so-called Holocaust controversies, especially for research into the participation of historians in these notoriously difficult discussions
Identification and evaluation of linear damping models in beam vibrations
Sensitive method, identifying effective damping mechanisms, involves comparing experimentally determined ratio of first to second mode magnification factors related to common point on beam. Cluster size has little effect on frequencies of elements, magnification factor decreases with cluster size, and viscous and stress damping are dominant damping mechanisms
Haze in the Klang Valley of Malaysia
Continuous measurements of dry aerosol light scattering (Bsp) were made at two sites in the Klang Valley of Malaysia between December 1998 and December 2000. In addition 24-h PM2.5 samples were collected on a one-day-in-six cycle and the chemical composition of the aerosol was determined. Periods of excessive haze were defined as 24-h average Bsp values greater than 150 Mm-1 and these occurred on a number of occasions, between May and September 1999, during May 2000, and between July and September 2000. The evidence for smoke being a significant contributor to aerosol during periods of excessive haze is discussed and includes features of the aerosol chemistry, the diurnal cycle of Bsp, and the coincidence of forest fires on Sumatra during the southwest (SW) monsoon period, as well as transport modelling for one week of the southwest Monsoon of 2000. The study highlights that whilst transboundary smoke is a major contributor to poor visibility in the Klang Valley, smoke from fires on Peninsular Malaysia is also a contributor, and at all times, the domestic source of secondary particle production is present
Bogoliubov speed of sound for a dilute Bose-Einstein condensate in a 3d optical lattice
We point out that the velocity of propagation of sound wavepackets in a Bose-Einstein condensate filling a three-dimensional cubic optical lattice undergoes a maximum with increasing lattice depth. For a realistic choice of parameters, the maximum sound velocity in a lattice condensate can exceed the sound velocity in a homogeneous condensate with the same average density by 30%. The maximum falls into the superfluid regime, and should be observable under currently achievable laboratory conditions
A complete representation of uncertainties in layer-counted paleoclimatic archives
Accurate time series representation of paleoclimatic proxy records is
challenging because such records involve dating errors in addition to proxy
measurement errors. Rigorous attention is rarely given to age uncertainties
in paleoclimatic research, although the latter can severely bias the results
of proxy record analysis. Here, we introduce a Bayesian approach to represent
layer-counted proxy records – such as ice cores, sediments, corals, or tree
rings – as sequences of probability distributions on absolute, error-free
time axes. The method accounts for both proxy measurement errors and
uncertainties arising from layer-counting-based dating of the records. An
application to oxygen isotope ratios from the North Greenland Ice Core
Project (NGRIP) record reveals that the counting errors, although seemingly
small, lead to substantial uncertainties in the final representation of the
oxygen isotope ratios. In particular, for the older parts of the NGRIP
record, our results show that the total uncertainty originating from dating
errors has been seriously underestimated. Our method is next applied to
deriving the overall uncertainties of the Suigetsu radiocarbon comparison
curve, which was recently obtained from varved sediment cores at Lake
Suigetsu, Japan. This curve provides the only terrestrial radiocarbon
comparison for the time interval 12.5–52.8 kyr BP. The uncertainties
derived here can be readily employed to obtain complete error estimates for
arbitrary radiometrically dated proxy records of this recent part of the last
glacial interval
