This paper analyzes the impact of biased beliefs on the structure of informational equilibria in classical self-selection models. Using the intuitive insurance market example of Rothschild-Stiglitz (1976) I show that biases of high-risk individuals have fundamentally different effects on equilibrium contracts than biases of low-risk individuals. Whereas equilibrium contracts of both groups are ...

INTRODUCTION Suicide is one of the most prominent problems in health care system in current Iran. It could be impacted by various factors such as social, economic, individual and so on. Researchers show that socio-economic factors and suicide has significantly related. The people in low social class may more engage with social problems than higher social class. They may confront to problems suc...

Through joined two sensitive methods solvation and cloud point extraction separated and determined micro amount of Ce(III) from aqueous solutions by using organic reagent 2,4-Dimethyl pentan-3-one (2,4-DMP) as extractant and non-ionic surfactant 1% TritonX-100 , the experimental study shows the solvation species of Ce+3 extracted into cloud point layer (CPL) have a wavelength for maximum absorb...

The new species is a member of an apparently monophyletic group within the genus that includes R. flexile, R. walga, R. himanturi, R. burgeri, R. euzeti, R. hawaiiensis, R. urobatidium, R. paratrygoni, R. ditesticulum, R. tetralobatum, R. margaritense, R. biorchidum, and R. spinicephalum. All of these species have bothridia with medial longitudinal septa, a constriction at mid-bothridium, and, ...

VarietyCash is a new electronic money system which strikes a balance between functionality, security, and user privacy. The system can encompass both network and stored-value card based payment mechanisms, with transferability between them, hence the name. Department of Computer Science & Engineering, Mail Code 0114, University of California at San Diego, 9500 Gilman Drive, La Jolla, CA 92093, ...

IDEA is a block cipher designed by Xuejia Lai and James L. Massey and was first described in 1991. IDEA does not vary the constant in its key schedule. In [1], Donghoon Chang and Moti Yung showed that there may be a weakness of hash function based on block cipher whose key schedule does not use various constants. Based on their result, we investigate the security of double block length compress...

We ll a gap in the theory of zero-knowledge protocols by presenting NP-arguments that achieve negligible error probability and computational zero-knowledge in four rounds of interaction, assuming only the existence of a one-way function. This result is optimal in the sense that four rounds and a one-way function are each individually necessary to achieve a negligible error zero-knowledge argume...

Addit ion of either 25% or 50% bovine follicular fluid (FF) to Krebs Ringer phosphate buffer, with .5% fructose added (KRPF), maintained higher percentages (P<.05) of motile sperm throughout 9-hr incubation at 37 C than did 100% KRPF or 100% FF. Accelerated sperm moti l i ty and head-to-head agglutination of sperm cells were consistently observed in all diluents that contained FF. The percentag...

Predicting and characterizing the crystal structure of materials is a key problem in materials research and development. We report the results of ab initio LDA/GGA computations for the following systems: AgAu, AgCd, AgMg, AgMo∗, AgNa, AgNb∗, AgPd, AgRh∗, AgRu∗, AgTc∗, AgTi, AgY, AgZr, AlSc, AuCd, AuMo∗, AuNb, AuPd, AuPt∗, AuRh∗, AuRu∗, AuSc, AuTc∗, AuTi, AuY, AuZr, CdMo∗, CdNb∗, CdPd, CdPt, CdR...

El objetivo del artículo es dar cuenta proceso de construcción y validación un instru- mento diseñado para conocer las motivaciones causas por cuales los académicos uni- versitarios en Chile, habiéndose pensionado o no, retrasan el inicio la etapa jubilación. Para estos efectos se construyó cuestionario compuesto 62 ítems, agrupados siete sub-dimensiones. Dicho ha sido respondido 94 universitar...
