dual job holding is widespread in iran’s labor market, 18% of work force are holding second job in 1993, which increased to 19% in 2003. using a rich three years panel data-set of socioeconomic characteristics of iranian households, the article aims to examine the determinants of dual job holding across the individuals who have participated in the labor market. since the issue of dual job holdi...
let $x$, $y$ and $z$ be banach spaces and $f:xtimes y longrightarrow z$ a bounded bilinear map. in this paper we study the relation between arens regularity of $f$ and the reflexivity of $y$. we also give some conditions under which the arens regularity of a banach algebra $a$ implies the arens regularity of certain banach right module action of $a$ .
The notion of strongly Lie zero-product preserving maps on normed algebras as a generalization of Lie zero-product preserving maps are dened. We give a necessary and sufficient condition from which a linear map between normed algebras to be strongly Lie zero-product preserving. Also some hereditary properties of strongly Lie zero-product preserving maps are presented. Finally the second dual of...
Let $ (A,| cdot |) $ be a real Banach algebra, a complex algebra $ A_mathbb{C} $ be a complexification of $ A $ and $ | | cdot | | $ be an algebra norm on $ A_mathbb{C} $ satisfying a simple condition together with the norm $ | cdot | $ on $ A$. In this paper we first show that $ A^* $ is a real Banach $ A^{**}$-module if and only if $ (A_mathbb{C})^* $ is a complex Banach $ (A_mathbb{C})^{...
Objective: KinesioTaping is a method for rehabilitation of patients and athletes. The efficacy of taping to enhance proprioception precision and balance has been studied. The effects on skin sensory receptors and limb consciousness are mechanisms of taping but there is an important question that if the persons pay attention to other task the effectiveness of taping is still exists or not? ...
