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

Evaluating mixing modelling for soil erosion hot spot identification through the use of artificial soil mixtures
No full textSoil erosion and associated sediment redistribution are key environmental problems in Central Argentina. Several land uses and managementpractices, such as intensive grazing and crop cultivation, are considered to drive and increase significantly these processes. To prove this above hypothesis, a mixing modelling approach (CSSIAR v1.00),usingEnergy Dispersive X Ray Fluorescence (EDXRF) data as fingerprint of sediment sources and sinks,is aimed to identify critical hot spots of erosion in a typical Argentinian agro-ecosystem. The study site is an Estancia Grande subcatchmentwith an area of 1235 hectares, located 23 km north east of San Luis (in the center of Argentina) and which is characterized by highly erodible Haplic Kastanozemsoils.Fil: Torres Astorga, Romina Vanesa.

C as a short-term indicator of drought stress in banana
No full textWater shortage is the most important abiotic limitation for banana. The development of climate-smart cultivars and agronomic practices is ongoing, but the process is hindered by a lack of field-applicable drought stress evaluation methods. Earlier research indicated that carbon isotope discrimination values in bulk leaf material (δ13Cbulk) could serve as a proxy for drought stress in banana. However, δ13Cbulk is a time-integrated measure of stress. Information about current and short-term conditions could be useful for early stress detection or to observe diurnal variations in stress. Phloem sap contains recently assimilated carbon. Its δ13C value (δ13Cphloem) has successfully been used as a short-term indicator of drought stress in trees. We have developed a phloem sap sampling method for banana and evaluated it in a field experiment in Arusha, Tanzania. We compared δ13Cphloem with δ13Cbulk under two different watering treatments (irrigated and rainfed) and assessed diurnal variations by sampling in the morning (08:00) and at noon (12:00). Samples were collected during the dry season. Both δ13Cbulk and δ13Cphloem were significantly affected by the watering treatments, although the effect on δ13Cphloem was greater. This indicates the more sensitive and recent nature of δ13Cphloem. In addition, δ13Cphloem differed throughout the day, while δ13Cbulk did not. δ13Cphloem was higher at noon than in the morning, likely due to the occurrence of instantaneous drought stress. This difference in δ13Cphloem between morning and noon was larger in the irrigated treatment than in the rainfed treatment. Probably, the more severe stress in the rainfed treatment already led to partial stomatal closure in the morning, resulting in a higher δ13Cphloem and a smaller difference with δ13Cphloem at noon. Such short-term diurnal variations could not be detected with δ13Cbulk. δ13Cphloem can be used as an indicator for instantaneous drought stress, creating the possibility to investigate short-term changes in stomatal dynamics at field scale and possibly the early detection of stress.sponsorship: Peaceful Uses Initiative of IAEAstatus: Published onlin

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.

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
