We derive a representation theorem for time preferences (on the prize-time space) which identifies a novel notion of relative discounting as the key ingredient. This representation covers a variety of time preference models, including the standard exponential and hyperbolic discounting models and certain nontransitive time preferences, such as the similarity-based and subadditive discounting mo...

In important situations, individual decision-making is systematically biased. When deciding (rather than consuming), extrinsic attributes of choice options are more salient than intrinsic attributes. People overestimate extrinsic attributes and therefore put too much effort into acquiring income and gaining status, lowering their utility level. These mistakes are accentuated in authoritarian sy...

We study the outcome of the amendment voting procedure based on a potentially incomplete preference relation. A decision-maker evaluates candidates in a list and iteratively updates her choice by comparing the status-quo to the next candidate. She favors the status-quo when the two candidates are incomparable according to her underlying preference. Developing a revealed preference approach, we ...

delayed chondrocyte differentiation since Indian hedgehog (Ihh) is not expressed in the ulna of Ulnaless or Hoxa11//d11/ mice. Fibroblast growth factor 3 (Fgfr3), which is expressed at low levels in distal cells and at high levels in columnar chondrocytes, shows low expression in the Ulnaless and Hoxa11//d11/ zeugopod resembling the expression level in distal chondrocytes. However, the Unique c...

Abstract The aim was to explore potential differences on ghrelin plasm concentrations between efficient and inefficient lambs within a transient surge of secretion just before scheduled meal feeding. Six high- (256±19 g) six low-RFI (-242±19 Hampshire entire male (Age=168±2 d BW=63±5 kg) were taken out 25 individuals in 56-d GrowSafe SystemsÒ feeding trial. After 10-d adaptation once-daily ad-l...

Compelling evidence indicates that protein kinase CK2 plays an important role in many steps of cancer initiation and progression, therefore, the development of effective and cell-permeable inhibitors targeting this kinase has become an important objective for the treatment of a variety of cancer types including glioblastoma. We have recently identified 1,3-dichloro-6-[(E)-((4-methoxyphenyl)imin...

We introduce a search model where products differ in horizontal attributes and unobserved quality (“experience goods”), firms can establish reputation. show that the inability of consumers to observe before purchase significantly changes how frictions affect market performance. In equilibrium, higher costs reduce match values increase price but boost firms’ investment product quality. Under pla...

در بخشی از این کار تحقیقاتی گونه های آمفیفیلیک جدیدی از بتاسیکلودکسترین توسط برقراری پیوند استری زنجیره های پپتیدی با تمامی گروه های هیدروکسیل نوع اول بتا سیکلودکسترین طراحی و سنتز شد. ساختارهای آمفیفیلیک (a-d11) از تشکیل پیوند استری ما بین کربن ششم(c6) بتا سیکلودکسترین و گروه کربوکسیل ترکیبات (8 ، 6، 4، 2) تهیه شدند. مسیر سنتزی ابتدا شامل تهیه n-استیل-l-لوسین (2) از -l-لوسین در حضور استیک انید...
