Endogenous Fixprices and Sticky Price Adjustment of Risk-averse Firms
No full textA risk-averse price-setting firm which knows the quantity demanded at the status quo price but has imperfect information otherwise may choose not to change it although an otherwise identical risk-neutral firm would do so, provided the variance of the firm's subjective probability distribution over quantities demanded as a function of price displays a kink at the status quo. This is equivalent to risk aversion of order one. When no such endogenous fixprice exists, the size of price adjustment still tends to zero as risk aversion tends to infinity, and to any arbitrarily small menu cost there exists a degree of risk aversion so that the firm will not adjust.fixed prices, price adjustment, risk aversion, menu cost
Treating gastro-oesophageal reflux disease (GERD) with sense
No full textGastro-esophageal reflux disease (GERD) is a common disorder that affects an estimated 5 % to 7 % of the global population. Management of GERD often poses a number of challenges. In this article, the author presents a number of management modalities for this condition.peer-reviewe
La place de la guerre de 1914-1918 dans l'histoire culturelle de l'Allemagne
No full textThe place of the 1914-1918 war in the cultural history of Germany, Gerd Krumeich.
Through his study of war accounts and memories, the author analyses the impact of the war experience on German culture in its individual as well as its collective aspects. That impact brought about the continuation and the diffusion of militarism and nationalism in much of the German society of the 1920s and 1930s.Krumeich Gerd.

Differences in cerebral response to esophageal acid stimuli and psychological anticipation in GERD subtypes-An fMRI study
No full textBackground: To evaluate whether there are differences in the cerebral response to intraesophageal acid and psychological anticipation stimuli among subtypes of gastroesophageal reflux disease (GERD)
Augmenting a pH Medical Study with Wearable Video for Treatment of GERD
No full textIn this paper we present an augmentation to the wearable computers typically used to determine if a patient is a candidate for surgery to correct problems associated with Gastroesophageal Reflux Disease (GERD). A wearable camera was used by the first author while participating in a 24–hour stomach acid pH study. After the study’s conclusion, an examination of the captured video and pH record revealed some results that allowed the first author to avoid many of the activities that result in symptoms related to GERD. 1 GERD and Medical Testing Gastroesophageal Reflux Disease is a medical condition that affects 2 % of the adult population of the United States. GERD refers to the reflux of stomach acid into the esophagus and can lead to complications such as esophageal cancer and lung damage. The most common symptom of GERD is heartburn. Typical treatments for GERD include diet modification and medication; however, for some patients these treatments may prove ineffective, and the patient may be evaluated for more drastic measures such as surgery. If surgery to correct GERD is considered an option, the patient usually undergoes a 24 – or 48–hour pH study to measure the percentage of time that the patient is in reflux during normal daily activities. In the 24–hour study, a pH probe is inserted into the subject’s nose and lowered through the esophagus to a position above the stomach. Since the probe is attached to a line that is retained in the patient’s nose and throat, several pH sensors can be placed at varying locations along the patient’s esophagus. The probe is attached to a wearable computer which records the patient’s pH levels for 24 hours. The patient typically uses the wearable computer to record times of meals, periods spent in a supine position (e.g. sleeping), and occurrences of symptoms. The first author suffered from severe and relatively un

Modelling the vegetation of the Weser estuary in response to climate change using Classification tree analysis (CART) and GIS
No full textThe objective of this thesis was to develop a GIS-based model to predict changes of vegetation types due to climate change and sea level rise. The investigation area was the Weser estuary in northern Germany covering 50 km2. Classification tree analysis (CART) was used to test specific environmental variables affecting the land use and the dominant vegetation patterns of the tidal wetlands based on two different land use scenarios. The predictive accuracy was assessed using cross validation. The hit rate varied between 65 % for the land use types and 81 % for the vegetation types. The vegetation of the Weser estuary was modelled using explanatory topographic and hydrological variables. The CART model produced accurate and plausible predictions. The results illustrate the qualification and suitability of the modelling approach to predict changes of vegetation types for estuaries. The thesis is based upon the results of the BMBF project 'Klimaänderung und Unterweserregion' (KLIMU)
Ecotoxicological evaluation of soil remediation using a battery of bioassays: The case of TNT-contaminated soils
No full textThe objective of the presented research was to address the suitability of a battery of bioassays for a site-specific ecotoxicological evaluation of contaminated soils. Experimental fields are located at an abandoned armament site where the topsoil was contaminated by the explosive 2,4,6-Trinitrotoluene (TNT) and several co-contaminants. At this site, different soil treatments were established at technical scale to investigate the efficiency of a newly developed phytoremediation technology. Being part of an extensive monitoring programme, the test battery was intended to evaluate changes of soil toxicity in the course of remediation. The battery was compiled of five rather standardised test methods used in ecotoxicology: a phytotoxicity test with garden cress (Lepidium sativum), a springtail reproduction test with Folsomia candida (Collembola) and soil respiration measurements (basal and substrate induced respiration). In addition to these soil assays two aquatic tests based on the luminescent bacterium Vibrio fischeri (acute toxicity and mutagenicity) were included to assess the toxicity of aqueous soil extracts. Biological data generated by the test battery reveal a differentiated toxicity of complex contaminated soil samples. Observed differences in toxicity are in relative agreement with a gradient of TNT-contamination between experimental fields as described by chemical analyses. The five bioassays revealed clear differences in sensitivity. The acute luminescent bacteria toxicity test conducted with soil leachates proved to be a sensitive screening indicator of water-extractable toxicity. Bioassay data from all treatment variants largely indicate a reduction of soil toxicity during a 17 months remediation period, supposedly reflecting decreased soil concentrations of nitroaromatic compounds as shown by chemical analyses. These observations indicate a positive impact of the remediation procedures applied, but further monitoring is essential
Loss, Perseverance, and Triumph: The Story of Gerd and the von Halle Family
No full textThe following narrative details the life of Gerd von Halle. Gerd was a German Jew who moved to Amsterdam to escape Nazi persecution in 1933. The von Halle family was a prominent German Jewish family with origins dating back to the 17th century. Shortly after the invasion of Holland, Gerd and his family were torn apart by the Nazis. With the help of the Dutch Underground, Gerd and his mother Henriette survived the war. The narrative recounts the deaths of both his father and brother through recovered letters and personal testimony. The paper also contains correspondence between Eleanor Roosevelt and Under Secretary of State Sumner Welles. Both Roosevelt and Welles tried to help the von Halle family escape Europe. Gerd’s story provides an opportunity to look into the paranoia, fear, and resolution of the Jewish people during the Holocaust. After living in hiding for nearly three years, Gerd and his mother were liberated in Amsterdam in May 1945. Gerd immigrated to the United States in 1946. The paper is joined with a visual guide containing letters, false identity papers, falsified affidavits, and a multitude of photographs. The narrative is a testament to perseverance, loss, and triumph.
