We explore the effects of social distance in experiments conducted over the Internet on three continents, in classroom laboratory sessions conducted in Israel and Spain, and in computer sessions pairing participants from different states, one in Texas and the other in California. Our design elicits individual behavior profiles over a range of contingencies, enabling us to identify heterogeneity...

Methods We performed a nation-wide analysis of coded sepsis cases from 2007 to 2013 based on German Diagnosis Related Groups Statistics, Hospital Statistics, and Causes of Death Statistics. Sepsis cases were identified by a) clinical sepsis codes for sepsis, severe sepsis and septic shock (R65.0!, R65.1!, R57.2, respectively, as secondary diagnosis) from the DRG Statistics and b) microbiologica...

Formation and Distribution of Beachrock Beachrock is defined by Scoffin and Stoddart (1987, 401) as "the consolidated deposit that results from lithification by calcium carbonate of sediment in the intertidal and spray zones of mainly tropical coasts." Beachrock units form under a thin cover of sediment and generally overlie unconsolidated sand, although they may rest on any type of foundation....

The standard procedure in experimental economics maintains anonymity among laboratory participants, yet many field interactions are conducted with neither complete anonymity nor complete familiarity. When we are involved in interactive situations in the field, we usually have some clues concerning the characteristics of others; however, in some environments (such as e-commerce) these clues may ...

Four maize (Zea mays L.) inbreds representing genetic differences in seedling cold tolerance were used to determine the effect of growth temperatures on dry weight accumulation and mitochondrial properties, especially the alternative oxidase capacity. Seedlings were grown in darkness at 30 degrees C (constant), 14 degrees C (constant), and 15 degrees C for 16 hours and 8 degrees C for 8 hours. ...

This article answers Dr. Humphrey contention on the similarities between monetarist and Austrian approaches to neutrality of money. Monetarists at most only concentrate short term non while Austrians base their analysis in short, medium long neutrality. For more, monetarists lack a true theory capital that could let then understand thet even with flexible markets money would not be neutral term...

milton friedman’s seminal article, “methodology of positive economics”, is one of the most important and contentious works ever been discussed within the realm of economic methodology. in this article, on the basis of an instrumentalist approach to the nature of theorizing, friedman declares the tenets of positive economics, and in this vein, he professes his disputable doctrine about “unrealis...

In social-learning environments, we investigate implications of the assumption that people naively believe that each previous person’s action reflects solely that person’s private information, leading them to systematically imitate all predecessors even in the many circumstances where rational agents do not. Naive herders inadvertently over-weight early movers’ private signals by neglecting tha...

We have studied the expression of the NG2 chondroitin sulfate proteoglycan on bipotential glial precursor cells in cultures of postnatal rat optic nerve. Purified populations of these precursor cells were prepared by panning dissociated optic nerve cells on dishes coated with monoclonal A2B5 antibody. Using immunofluorescence double staining, we found that NG2 was present on almost 95% of the p...
