    Notes: Wavelength dispersive x-ray measurements on cobalt and krypton ions were presented to determine the ion charge state distribution (CSD) inside the electron cyclotron resonance (ECR) plasma of the 14.5 GHz ECR ion source of the TU Dresden. For clearly from the parent diagram lines separating x-ray satellites a comparison between calculated wavelength shifts and measured ones allows it to deduce the ion CSD of the analyzed ions. In the case of small line shifts (lower ionization states) a comparison with x-ray spectra derived from plasma modeling is done. By approximating the modeled spectra to the measured ones a most probable ion CSD was derived. © 1998 American Institute of Physics.

    Notes: Energy dispersive x-ray spectroscopy of Kα transitions of neon and chlorine ions inside an electron cyclotron resonance (ECR) plasma is used to analyze the ion charge state distribution (CSD) inside the plasma. Basing on a computer code describing time dependent and stationary solutions of the balance equations for the CSD in ECR plasmas (considering single and multiple ionization and charge exchange processes, radiative recombination, vacancy cascades, and electron shake-off) and considering atomic properties (fluorescence yields, transition rates, x-ray energy shifts, x-ray production cross sections) of ions with different charge states, an approximation of simulated x-ray spectra to measured ones is possible. Thus the result we get is the corresponding CSD and information about the electron energy distribution function in the low energy region in the plasma. © 1998 American Institute of Physics.

    Notes: The Comparison of Balloon versus Rotational Angioplasty (COBRA) study is a prospective, randomized study to compare short- and long-term effects of PTCA and high speed PTCRA (or rotablation) in patients with complex coronary stenoses. Patients with angiographically defined complex coronary stenoses (〉 70% diameter reduction) are included in the study. The trial has recruited 501 patients who will have detailed follow-up for 6 months. The primary end points are: (1) procedural success, defined as angiographically proven residual stenoses 〈 50% and stenosis reduction of ± 20% in absence of new myocardial infarction, emergency CABG, or death; (2) 6-month restenosis in the treated segment; and (3) major cardiac events during the follow-up period. Additionally, improved exercise tolerance will be scored. The final results of the study are expected by late 1997.

    Notes: Summary We report three cases of acute generalized exanthematous pustulosis (AGEP) following oral administration of nystatin. All cases showed similar clinical features and hislopathological findings, and a delnyed-type hypersensitivily to nystatin could be demonstrated in patch and prick testing. Drug eruptions to nystatin are extremely rare, and, to our knowledge, AGEP has not been reported previously.

    Notes: Thomas' paper and manuscript are ambitious. He aims at nothing less than opening up for discussion fundamental concepts which have informed archaeological writings to date. While in principal laudable and exciting, the chosen concepts – time, culture and identity – are broad, each one on its own of daunting complexity. The vastness of the project is handled by setting up an opposition at the outset between the Cartesian and modernist reading of these concepts adopted by archaeology and an anti-Cartesian and anti-modernist reading facilitated by Heidegger. At issue is less the validity of Heidegger's writings or their deployment in contemporary theory-making, a fact which the author is at pains to defend, though leaving the novice at pains guessing what his writings are actually about; at issue is whether the future of archaeology should rest on developing an anti-Cartesian theory in the first place. The mind/body dualism associated with Descartes has been the subject of much critical work, so much so that it seems at best unnecessary to have to revive Heidegger to give Cartesianism the final blow. One may further question the opposition itself; is it not Kant who is the foundation of post-Enlightenment thought, rather than Descartes, and would thus not his writings be the point of departure for any rethinking of theoretical assumptions that may have guided archaeological theory and practice? A third reservation may be voiced about the validity of the interpretative approach itself; it rests on the assumption, also known as the logocentric paradigm, which holds that a relation exists between an object or image and a narrative description of it which is ‘found’ outside the object and thus may vary according to the context in which the object is seen. The most serious criticism to this assumption is that it ignores the immediacy of understanding which allows images to play a fundamental role in social transmission. Thomas' use of Heidegger's notion of Being appears to strive towards precisely such an immediacy of understanding, yet fails to do so by leaving accounted for the materiality of images. In advocating the interpretative approach, Thomas sets out less a new direction for archaeological theory than captures post-modernist writing which dominated across disciplines for the past decade and left a whole generation of scholars trained during this period ill-equipped to deal with artefacts in more than an exemplary manner. In the late 90s, however, due to advances in cognitive psychology and our day to day experience with cyberspace, this neglect of the image, material and conceptual, and its role in transmission has become glaringly obvious and unacceptable. Critical in their inception, however, paper and manuscript are intently thought provoking, stimulating and timely in calling for a rethinking of archaeological theory to accommodate the contemporary perception of material things. In my discussion I aim to both paraphrase the main points of Thomas's paper and manuscript and to offer comments and questions.

    Notes: Abstract Exponential families of stochastic processes are usually curved. The full exponential families generated by the finite sample exponential families are called the envelope families to emphasize that their interpretation as stochastic process models is not straightforward. A general result on how to calculate the envelope families is given, and the interpretation of these families as stochastic process models is considered. For Markov processes rather explicit answers are given. Three examples are considered some in detail: Gaussian autoregressions, the pure birth process and the Ornstein-Uhlenbeck process. Finally, a goodness-of-fit test for censored data is discussed.

    Notes: Abstract. Quality of life (QOL) in patients with gastric cancer who underwent total gastrectomy has so far not been studied using the EORTC QLQ-C30 (Quality of Life Core Questionnaire of the European Organization for Research and Treatment of Cancer) as a standardized European QOL instrument. The aim of this study was to evaluate the effect of radical procedures such as extensive lymph node resection and combined resection of adjacent organs on patients' QOL. From 1992 to 1996, 152 patients underwent total gastrectomy. All patients alive on July 1, 1996 were included in the study (77/152). For assessing QOL, the EORTC QOL questionnaire QLQ-C30 version 2.0 and a validated gastric cancer module were sent home to the patients for self-completion. The response rate was 91%. It was possible to evaluate the questionnaires of 62 patients who had undergone resection with curative intent including 13 extended gastrectomies (21%). Of the 62 resections, 50 were combined with D2 lymphadenectomy (80.6%). The global health status was not negatively influenced by D2 lymphadenectomy and extended gastrectomy. Patients with splenectomy were more affected by treatment than patients without splenectomy. Radical gastrectomy combined with D2 lymphadenectomy is the treatment of choice for gastric cancer patients, concerning not just survival but QOL as well.
