The line between lifestyle and social identity in sociology is based on the distinction between traditional and modern society. In traditional societies lifestyle and social identity are based on their related features. However, in this regard, in terms of time precedence, modern societies mainly offer two different answers, each based on different theoretical approaches. The first and the olde...

Like Phenol (C 6 H 5 OH) and Urea {(NH 2 ) 2 C=O)}, Furfuryl alcohol (C 4 H 3 OCH 2 OH), a product of agricultural origin is capable of polymerization with Formaldehyde (H 2 C = 0) under suitable PH conditions. However, usable polymers, at least as no bake for Foundry applications are obtained only when the condensations are carried out in association with Urea, Phenol or both. The series of re...

in literary histories written in both iran and the west it has generally be assumed that early modern persian literary works are (technically inferior) copies of western literary works. this has been and is still a claim. almost no academically and scientifically sound works has substantiated this claim. while there is no point in denying a european influence on early modern persian literature,...

Resum The optimum portfolio selection for an investor with particular preferences was proven to lie on the normalized efficient frontier between two bounds defined by the Ballestero (1998) bounding theorem. A deeper understanding is possible if the decision-maker is provided with visual and quantitative techniques. Here, we derive useful insights as a way to support investor?s decision-making t...

Max Weber attributes the rise of modern Western society to Puritanism, noting that the Calvinist Protestant found, in his lonely attempt to communicate directly with God, a sense of human dignity and individualism in agreement with the rational structure of democracy. Weber, however, asserts that Confucianism lacks the Protestant way of thinking and hence cannot help with the rise of a modern C...

Typically portfolio analysis is based on the expected utility or the mean-variance approach. Although the expected utility approach is the more general one, practitioners still appreciate the mean-variance approach. We give a common framework including both types of selection criteria as special cases by considering portfolio problems with terminal wealth constraints. Moreover, we propose a sol...

This paper examines the so called 1/n investment puzzle which has been observed in defined contribution plans whereby some participants divide their contributions equally among the available asset classes. It has been argued that this is a very naive strategy since it contradicts the fundamental tenets of modern portfolio theory. We use simple arguments to show that this behavior is perhaps les...
