Random risk aversion and the cost of eliminating the foreign exchange risk of the Euro

This paper answers the following questions. If the Euro foreign exchange risk is given, what is the cost of eliminating such a risk? How does risk aversion affect this cost? What is the relation between the insurance premium on the Euro and this cost? Is it possible to find out the level of risk aversion by looking upon actual risk-free yields? If risk aversion is random, how do risk-free yields move with the return on the Euro currency? Economists usually take for granted that preferences are stable. By contrast, business news networks mention frequently changing risk appetite, or changing investor sentiment, in order to explain market behavior. This paper shows that it is worthwhile to presume that risk aversion is random, because such randomness provides direct answers to the questions raised above.The Euro, foreign exchange risk, expected utility, cost of risk, risk aversion, risk compensation, insurance premium, risk-free yields, Monte Carlo simulations, bootstrap sampling, EU financial markets

Pancreatitis following Olanzapine Therapy: A Report of Three Cases

CONTEXT: Atypical antipsychotic agents (clozapine, olanzapine) have been linked to metabolic effects and acute pancreatitis. CASE REPORT: We reviewed the inpatient and outpatient records of three patients who developed acute pancreatitis while being treated with olanzapine. The mean age of the patients was 37.7 years (range 18–54 years, 2 female, 1 male). No alternative cause of acute pancreatitis was found in two of the three patients. In the remaining patient, olanzapine may have contributed to acute pancreatitis in the setting of hypertriglyceridemia. Olanzapine was discontinued in all instances. Over a mean follow-up of 14 months, one patient has had a relapsing course, but the remaining two patients have been symptom free without recurrence of acute pancreatitis. CONCLUSIONS: Our case series adds further support to the potential link between olanzapine use and acute pancreatitis. Close monitoring of metabolic parameters is suggested in patients treated with olanzapine. Alternative antipsychotic agents should be considered in patients at high risk for pancreatitis

Scheduling Packets with Values and Deadlines in Size-bounded Buffers

Motivated by providing quality-of-service differentiated services in the Internet, we consider buffer management algorithms for network switches. We study a multi-buffer model. A network switch consists of multiple size-bounded buffers such that at any time, the number of packets residing in each individual buffer cannot exceed its capacity. Packets arrive at the network switch over time; they have values, deadlines, and designated buffers. In each time step, at most one pending packet is allowed to be sent and this packet can be from any buffer. The objective is to maximize the total value of the packets sent by their respective deadlines. A 9.82-competitive online algorithm has been provided for this model (Azar and Levy. SWAT 2006), but no offline algorithms have been known yet. In this paper, We study the offline setting of the multi-buffer model. Our contributions include a few optimal offline algorithms for some variants of the model. Each variant has its unique and interesting algorithmic feature. These offline algorithms help us understand the model better in designing online algorithms.Comment: 7 page

Structure and Dynamics of the Instantaneous Water/Vapor Interface Revisited by Path-Integral and Ab-Initio Molecular Dynamics Simulations

The structure and dynamics of the water/vapor interface is revisited by means of path-integral and second-generation Car-Parrinello ab-initio molecular dynamics simulations in conjunction with an instantaneous surface definition [A. P. Willard and D. Chandler, J. Phys. Chem. B 114, 1954 (2010)]. In agreement with previous studies, we find that one of the OH bonds of the water molecules in the topmost layer is pointing out of the water into the vapor phase, while the orientation of the underlying layer is reversed. Therebetween, an additional water layer is detected, where the molecules are aligned parallel to the instantaneous water surface.Comment: 9 pages, 5 figure

Pengaruh Harga dan Penataan Produk (Display)terhadap Keputusan Pembelian dengan Kepuasan Konsumen sebagai Variabel Intervening pada Ud. Rejeki Agung Lamongan

This research was conducted at UD. REJEKI AGUNG Lamongan is engaged in marketing children\u27s toys. The purpose of this study was to determine how the influence of displays on purchasing decisions with customer satisfaction as an intervening variable at UD. REJEKI AGUNG Lamongan. The purpose of this study was to determine how much influence the display (product arrangement) on purchasing decisions with consumer satisfaction as an intervening variable. The population in this study were all consumers who had purchased the product in  2017. While the sample was 98 respondents using the Convinience Sampling method, which is a sampling technique that is easy to find. The results of this study indicate that the price and display partially affect Consumer satisfaction and Purchasing Decisions. And simultaneously also shows that price and display influences consumer satisfaction and purchasing decisions. Price variables give a greater influence on customer satisfaction and purchasing decisions
