august wilson is undoubtedly one of the rare black playwrights whose works have attracted streams of attention and worldwide audience. the present study aims at analyzing fences and piano lesson which are two of the most successful plays in his pittsburgh cycle from the perspective of michel foucault’s theories and ideas. studying these two plays from foucault’s perspective opens new windows in...

The concept of “Innovation” has changed considerably in recent years. According to new theories, the innovation emerges in a system of interrelated elements and determinants during which the idea changes to a commercialized output or process. The literature on the innovation has concentrated mainly on various aspects of innovation chain separately. In this paper we tried to investigate the gene...

Adipose tissue is an active endocrine organ that produces substances having local and systemic actions on blood vessels, kidneys, and the heart. Leptin, adiponectin, resistin, angiotensin II, adipsin, TNF, IGF-1, plasminogen-activator inhibitor 1, and prostaglandins compose an incomplete list.1 Resistin, an adipokine belonging to the cysteine-rich secretory protein family, was described as an a...

The purpose of this article was to estimate the effect of higher education on total productivity changes and technical efficiency in the 4-digit classification code of ISIC in Iran during the period of 1994-04. In this regard, a two-way stage approach was used. In the first stage, Malmquist Productivity Index (MPI) and technical efficiency index by Data Envelopment Analysis (DEA) and Stochastic...

the index is excellent by the malmquist index as extended to productivity measurement. the index developed here is defined in terms of input cost rather than input quantity distance functions in supply chain. therefore, we propose productivity change is decomposed into overall efficiency and cost technical change. these decompositions provide a clearer situation of the root sources of supply ch...

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

The paper begins with an objection to the DesireBased Reasons Model. The argument from reason-based desires holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of this argum...
